    Air-based fryer and accessory for an air-based fryer
    FIELD OF THE INVENTION The present invention relates to an air-based fryer.
    BACKGROUND OF THE INVENTION Air-based fryers are known, for instance from WO 2007/144432.
    Typically, they comprise a cooking chamber and an air-permeable basket for supporting food ingredients to be cooked. The basket defines a food receiving chamber. A flow of hot air is circulated around and through the food ingredients in the food receiving chamber with relatively high speed, providing the heat needed to cook the food. Thus, the food can be cooked in a healthy manner, with no or much less fat compared to conventional deep-fat frying.
    Air-based fryers can be used for preparing a large variety of food ingredients. However, the general operation involves placing the food items in a basket with a perforated base, so that air can flow through the food from beneath. The base is removable from the remainder of the basket for cleaning.
    It would be desirable to be able to cook a greater variety of food types in an air-based fryer.
    It is known to provide a cooking pot accessory which can be inserted into the cooking chamber so that food items with a liquid content can be cooked. An example is disclosed in US 2019/0045973.
    It would be desirable to provide further versatility to an air-based fryer. In particular, cooking vegetables in an air-based fryer results in drying out and loss of weight.
    SUMMARY OF THE INVENTION The invention is defined by the independent claims. The dependent claims define advantageous embodiments.
    According to examples in accordance with an aspect of the invention, there is provided an accessory for an air-based fryer, comprising: a vessel suitable for containing water;
    a support arrangement for mounting in the vessel, the support arrangement having at least one support grid for supporting a food to be steamed; and a lid, wherein the support arrangement is configurable in a first configuration with a support grid at a first height from a base of the vessel, for steaming food supported by the support grid, and in a second configuration with a support grid at a second height from the base of the vessel, for cooking food in water beneath the support grid and steaming food supported by the support grid.
    This accessory can be used for steaming food, by having a small volume of water beneath the support grid and placing food on the support grid to be steamed.
    When the support arrangement is in the first configuration, the support grid is then low down in the vessel so that there is a large space for the food to be steamed. When the support arrangement is in the second configuration, the support grid (or a different support grid) is higher up. This gives space both below the support grid for boiling food as well as above the support grid for steaming.
    If only boiling food is desired, the support arrangement may be removed and the vessel used as a boiling pot.
    Thus, accessory is versatile, allowing steaming, boiling, or both.
    The support arrangement may comprise two separate support structures (each with its own support grid), one of which is chosen to implement the first configuration and the other of which is chosen to implement the second configuration. Alternatively, a single support structure may have a support grid which can be adjusted in height. Alternatively, one of a two support grids may be selected for use in a single support structure.
    However, a preferred option is that the support arrangement comprises a single support structure and there is a single grid, wherein the support arrangement is selectively mountable in the vessel upright and upside down to define the first and second configurations respectively.
    In this way, there is a single accessory (so less storage space is needed), and it can be placed either way up in the vessel, to choose between a steaming mode or a steaming and boiling mode.
    The support grid may then be slidable between different first and second resting positions within the support structure, depending on whether the support arrangement is upright or upside down. In this way, an optimum support grid position is set when the support arrangement is upright and when it is upside down. It may for example be between one third and two thirds of the way up the vessel when the support arrangement is upside down.
    The support grid is for example less than 30 mm, for example less than 20 mm, from the base of the vessel in the first configuration, e.g. when the support arrangement is upright. Thus, only a little space is needed for the water to be used for steaming. A large space remains for the food to be steamed.
    The support grid may be between 30 mm and 80 mm from the base of the vessel when the support arrangement is in the second configuration, e.g. the support arrangement is upside down. This gives space for boiling, for example for cooking rice, as well as leaving space above for steaming as well.
    The vessel may be round when viewed from above. A typical food receiving basket of the air-based fryer is more square, and this means air flow passages are present at the corners.
    The vessel for example has a diameter in the range 150 mm to 250 mm and a height in the range 60 mm to 120 mm.
    The vessel is preferably metal, for optimum heat transfer.
    The support structure may comprise a cylindrical tube, with the support grid mounted within the tube perpendicular to the cylinder axis.
    The support grid is for example mounted between first and second ribs at different locations along the tube, and the support grid is slidable between positions in which it abuts one or other of the ribs. This provides the positional adjustment of the support grid, under gravity, when the support arrangement is moved between upright and upside down orientations.
    The vessel when closed by the lid for example has an escape vent arrangement for allowing steam to escape. This may be the interface around the lid (e.g. a poor seal), or there may be dedicated escape valves or vents. This prevent overpressure in the vessel during steaming.
    The accessory may further comprise a handle for allowing the vessel to be lifted in and out of a food receiving unit (i.e. the main basket) of the air-based fryer. Thus, the accessory is simply placed in the standard basket of the air-based fryer.
    The invention also provides an air-based fryer, comprising: a cooking chamber; a food receiving unit adapted to be removably received in the cooking chamber such that an air passage is formed all around the food receiving unit;
    a heater for heating air in the cooking chamber; a fan for circulating a flow of hot air in the cooking chamber through the air passage around the food receiving unit; and an accessory as defined above for placing in the food receiving unit. The food receiving unit is for example, viewed from above, square or rectangular, with rounded corners. The air-based fryer may have a maximum temperature setting of 200 degrees Celsius or lower, and wherein the accessory is for steaming or boiling of food with the air- based fryer at the maximum temperature setting. The invention also provides a method of using an air-based fryer, comprising: placing an accessory in a food receiving unit of the air-based fryer, the accessory comprising: a vessel suitable for containing water; a support arrangement for mounting in the vessel, the support arrangement having at least one support grid for supporting a food to be steamed; and a lid, selecting a first or second configuration of the support arrangement; for the first configuration, in which a support grid is at a first height from a base of the vessel, the method comprises using the accessory to steam food supported by the support grid, and for the second configuration, in which a support grid is at a second height from the base of the vessel, the method comprises using the accessory to cook food in water beneath the support grid and steam food supported by the support grid. Selecting a configuration for example comprises selecting an upright mounting of the support arrangement in the vessel for the first configuration or selecting an upside down mounting of the support arrangement in the vessel for the second configuration. These and other aspects of the invention will be apparent from and elucidated with reference to the embodiment(s) described hereinafter.
    BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of the invention, and to show more clearly how it may be carried into effect, reference will now be made, by way of example only, to the accompanying drawings, in which: Figure 1 shows a known design of air-based fryer in cross-sectional view;

    DETAILED DESCRIPTION OF THE EMBODIMENTS The invention will be described with reference to the Figures.
    It should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the apparatus, systems and methods, are intended for purposes of illustration only and are not intended to limit the scope of the invention. These and other features, aspects, and advantages of the apparatus, systems and methods of the present invention will become better understood from the following description, appended claims, and accompanying drawings. It should be understood that the Figures are merely schematic and are not drawn to scale. It should also be understood that the same reference numerals are used throughout the Figures to indicate the same or similar parts.
    The invention provides an accessory for an air-based fryer, comprising a vessel which receives a support arrangement having at least one support grid for supporting a food to be steamed. The accessory has two configurations, one with a small space for water beneath a support grid and a large space above for food to be steamed, and one with a large enough space beneath a support grid for boiling food but still a sufficient space above for steaming.
    Figure 1 shows a known design of air-based fryer 1 in cross-sectional view. The air-based fryer 1 comprises a cooking chamber 2 with sidewalls 3, a bottom wall 4, and a top wall 5. A food receiving unit 10 (a main basket) is disposed within the cooking chamber 2 to support food F to be cooked.
    The basket 10 comprises an air-permeable bottom 12 and solid side walls 14.
    It has an open top, although a permeable cover plate may also be provided. The bottom 12 for example comprises a wire mesh which is a snap fit into the base of the basket within the side walls 14. The wire mesh is for example removable for cleaning, e.g. in a dishwasher, whereas the remainder of the basket is typically wiped clean by the user.
    A mounting structure 15 is provided to detachably mount the basket 10 in the cooking chamber 2. The mounting structure 15 is designed to allow air to circulate all around the basket 10 in the mounted condition. The mounting structure 15 is designed such that in mounted condition a bottom gap 16a is provided between the air-permeable bottom 12 and the bottom wall 4 of the cooking chamber 2. Furthermore, a lateral gap 16b is provided between the sidewalls 3 of the cooking chamber 2 and the perimeter of the air-permeable bottom 12. The bottom gap 16a and lateral gap 16b together form part of an air circulation channel.
    The mounting structure 15 is designed to minimize obstruction of said air circulation channel.
    In some embodiments, as illustrated in Figure 1, the mounting structure 15 comprises a handle, with which the basket 10 may be suspended from a sidewall 3 of the cooking chamber 2. The handle allows a user to easily remove the basket 10 from the cooking chamber 2.
    The air-based fryer 1 further comprises an air circulation system comprising a fan 17, a motor 19 and an air heater 18 for circulating hot air in the cooking chamber 2. The air heater 18 may be disposed above the basket 10. In such a case, the air heater 18 may radiate heat directly to the food ingredients F in addition to heating the air in the cooking chamber 2.
    The air circulation system may also be disposed above the basket 10 for example above the air heater 18.
    The air circulation system is designed to pass hot air through the air-permeable bottom 12 of the basket 10 such that food F disposed thereon will be prepared by a through- streaming of hot air.
    The air circulation system in this example is designed to draw air upward through the basket 10 as shown by arrows 13. The air may subsequently be passed along the air heater 18 to heat the air. The air heater 18 may be any appropriate heating source, such as an electric heater which can heat air to, for example, between roughly 100 °C and 250 °C by controlling the power supplied to the air heater.
    As shown by arrows 11, the air circulation system is designed to pass hot air downward along an inner surface of the cooking chamber 2 and an outer surface of the basket 10. The bottom gap 16a and lateral gap 16b together form an air circulation channel for guiding the flow of hot air from the air circulation system to the bottom 12 of the basket 10.
    The bottom wall 4 of the cooking chamber 2 may be flat or as shown in Figure 1 the bottom wall 4 may be provided with an air guide member 20 configured to direct the hot air flow towards and/or through the air-permeable bottom 12 of the basket 10.
    The air guide member 20 may have a substantially conical, or frusto-conical outer contour or it may comprise ribs or arms. The air guide member 20 may be integrally formed in the bottom wall 4 of the cooking chamber or be provided as a separate insert.
    In the example shown, a deflector plate 24 is provided in an upper part of the cooking chamber 2 above the basket 10, to further enclose a volume enclosed by the basket 10, and to help guiding air from the air circulation system 6 around the basket into the air circulation channel formed by the bottom gap 16a and lateral gap 16b.
    The cooking chamber 2 is shown with an upper section 2a and a lower section 2b, separable from each other to enable access into the cooking chamber 2. The upper section 2a thus functions as a cooking chamber lid. In some embodiments, the lower section 2b may be arranged stationary and the upper section 2a may be releasably or hingedly arranged, e.g. in the form of a lid. In some embodiments, the upper section 2a may be arranged stationary and the lower section 2b may be releasably arranged, e.g. in the form of a drawer. In such case, the lower section 2b may comprise a handle 22 to aid removal of the lower section 2b from the air-based fryer 1, as illustrated in Figure 1. The handles 15 and 22 couple together to define a single handle for the user to manipulate.
    The air-based fryer 1 may comprise a vent (not shown), defining an air outlet from the cooking chamber 2 to outside the air-based fryer 1.
    In use, a variety of food types may be prepared in the air-based fryer 1. In case where the food is a bulk type of food, the individual food ingredients F may form a pile as illustrated in Figure 1, with the height, density and consequently the flow resistance being highest in the center of the pile and decreasing towards the periphery.
    The bottom 12 of the basket 10 may for example be designed to have a flow resistance that reversely mirrors the flow resistance of the pile, so is lowest in the center and increases towards the periphery. Thus, the total flow resistance of the bottom 12 and pile together may be more or less constant over the entire cross section of the basket 10, resulting in a more homogeneous air flow through the basket 10 and, ultimately, in more homogeneous cooking results.
    The invention provides an accessory for an air-based fryer, and an air-based fryer having the accessory, the accessory enabling steaming and/or boiling of food. The accessory fits inside the existing basket 10.
    Figure 2 shows the accessory 30 in schematic form mounted inside the basket
    10.
    Figure 3 shows an example of the accessory design in detail.
    The accessory 30 comprises a vessel 40 with a solid base 42 and side wall 44 such that water can be contained in the vessel 40. The vessel is for example made of metal.
    A support arrangement 45 is for mounting in the vessel 40. The support arrangement has a support grid 46 for supporting a food to be steamed. The support grid 46 is for mounting within an outer wall 48. The outer wall is termed a "support structure” in that it supports the support grid.
    In the example shown, there is a single support structure (the wall 48) and a single support grid. However, there may be multiple support structures, each with its own grid at a different height up the support structure. The term "support arrangement” thus may include a single support structure and grid or it may include multiple support structures and associated grids. However, there is typically only a single vessel 40.
    There may instead be multiple grids, for example each for mounting at a different height within the support structure, so that a suitable grid is selected and then positioned in a same support structure. Thus, there may be more than one support grid, and only one is selected for use.
    There may instead be one grid but with adjustable height, for example adjustable legs, so that a suitable grid configuration is selected and then it is positioned in a same support structure.
    The description will follow for an example of support arrangement 45 with a single support structure (the outer wall 48) and a single grid 46. Furthermore, the example below is based on a support arrangement 45 which may be mounted either way up within the vessel 40.
    The outer wall 48 is spaced from the side wall 44 of the vessel when the support arrangement 45 is in position inside the vessel so that the outer wall 48 is not heated by conduction from the vessel side wall 44.
    The vessel is covered by a lid 50 and there is a handle 52 attached to the vessel 40 for lifting the vessel, the lid and the contained support arrangement 45, in and out of the air-based fryer basket.
    In the example shown, the outer wall 48 is formed as a cylindrical tube and the support grid 46 is mounted within the tube perpendicular to the cylinder axis. The outer wall prevents vegetables touching the vessel side wall 44, which may be too hot (e.g. 200 degrees
    Celsius) for direct contact with vegetables.
    The air gap between them provides a thermal barrier, whereas the water is in contact with the base 42 of the vessel 40 and thereby heated by conduction.
    The support grid 46 is mounted between first and second ribs 53, 54 at different locations along the tube.
    These ribs project inwardly into the volume of the cylinder and thereby define ledges which function as supports for the support grid.
    The support grid 46 is slidable between positions in which it abuts one or other of the ribs 53, 54. The outer wall 48 may tor example enlarge (open) and tighten (close) using a handle (not shown) so that the support grid may be removed.
    Thus, it may have a design similar to a cake tin with a separable base and side wall.
    In this particular example, the support arrangement is selectively mountable in the vessel 40 upright (as shown in Figure 3) and upside down.
    When upright, the support grid 46 is near the base of the vessel 40, in particular nearer to the base than the lid.
    A small amount of water may be housed beneath the support grid for steaming food supported by the support grid.
    The amount of water may for example be 50ml to 100ml for steaming 200g to 600g of vegetables.
    The volume defined between the base of the vessel and the support grid may tor example be between 100ml and 600ml.
    When upside down, the support grid 46 is closer to the lid than when the support arrangement 45 is upright.
    A larger volume is beneath the support grid, for example between 500ml and 1 liter, for cooking food in water beneath the support grid.
    However, a space remains above the support grid so that food can also be steamed.
    Thus, the accessory 30 can be used for steaming food, by having a small volume of water beneath the support grid and placing food on the support grid to be steamed.
    The support grid is then low down in the vessel so that there is a large space for the food to be steamed.
    When the support arrangement 45 is placed upside down, the support grid 46 is higher up.
    This gives space both below the support grid for boiling food as well as above the support grid for steaming.
    In the particular example shown, the support grid has an adjustable position relatively to the outer wall 48. Thus, when upside down, the support grid 46 is not right at the top of the vessel, but drops down, so that the support grid is roughly half way up the vessel (e.g. between one third and two thirds of the way up the vessel). This gives space for both boiling and steaming.
    For example, the accessory may be used for cooking rice (e.g. with a ratio of rice volume to water volume of 1:2) and steaming vegetables, at the same time.
    In both orientations, the outer wall 48 provides a barrier to the vessel side wall 44. This would not be the case for an outer wall which is only a fraction of the height of the vessel side wall 44 (but which would not then need the relative movement).
    It only boiling food is desired, the support arrangement 45 may be removed and the vessel and lid may simply be used as a boiling pot.
    Figure 4 shows example dimensions of the accessory in mm. One example set of dimensions is shown.
    More generally, the support grid is for example less than 30 mm, for example less than 20 mm, from the base of the vessel when the support arrangement is upright. This is the dimension shown as 20 in Figure 4 between the lower rib 54 and the base.
    The support grid may be between 30 mm and 80 mm from the base of the vessel when the support arrangement is upside down. This gives space for boiling, for example for cooking rice, as well as leaving space above for steaming as well. This is the space between the upper rib 53 and the top of the vessel, which is 30 mm in Figure 4 (the difference between the full height 60mm and the lower rib height 30 mm).
    The vessel for example has a diameter in the range 150 mm to 250 mm and a height in the range 60 mm to 120 mm.
    Figure 4 shows that the vessel is round when viewed from above.
    However, as shown in Figure 5, a typical food receiving basket 10 of the air- based fryer is more square, and this means air flow passages are present at the corners. This assists heat transfer to the accessory.
    The vessel when closed by the lid needs to allow steam to escape to prevent pressure build up. There may be a dedicated escape vent or the lid may simply provide a poor enough seal that it can allow steam to escape, or lift in use and allow steam to escape.
    The air-based fryer with which the accessory is to be used for example has a maximum temperature setting of 200 degrees Celsius or lower. The accessory is for example designed for steaming or boiling of food with the air-based fryer at this maximum temperature setting.
    In order to use the accessory, the accessory is placed in the basket (i.e. the food receiving unit) of the air-based fryer. An upright or upside down mounting of the support arrangement is chosen in the vessel.
    When mounted upright, the accessory is used to steam food supported by the support grid.
    When mounted upside down, the accessory is used for cooking food in water beneath the support grid and steaming food supported by the support grid.
    Of course, the terms upright and upside down are arbitrary. The steaming and boiling setting could instead be thought of as the upright orientation and the steaming only setting could be thought of as the upside down orientation.
    These and other aspects of the invention will be apparent from and elucidated with reference to the embodiment(s) described hereinafter.
    The invention may be applied to different types of air-based fryer, of which Figure 1 is only one example.
    Variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure and the appended claims. In the claims, the word "comprising” does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. A single processor or other unit may fulfill the functions of several items recited in the claims.
    The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measures cannot be used to advantage. A computer program may be stored/distributed on a suitable medium, such as an optical storage medium or a solid-state medium supplied together with or as part of other hardware, but may also be distributed in other forms, such as via the Internet or other wired or wireless telecommunication systems. Any reference signs in the claims should not be construed as limiting the scope.
