    [0001]
    [0002] Domestic refrigerator appliance.
    [0003]
    [0004] The invention is in the technical field of domestic refrigeration appliances, which comprises an inner lining forming at least one refrigerated cavity surrounded by thermal insulation material having a channel-shaped conformation directed towards the material on a structural wall of the cavity of thermal insulation with two parallel facing edges and a cover to cover the conformation at least in part, which is fixed to the edges slidably in the direction of the edges by means of fixing wings arranged in the perimeter of the cover, and at less a flap facing the conformation.
    [0005]
    [0006] In the patent application EP 2950020 A1 a domestic refrigerating apparatus is provided provided with an air distribution system comprising a refrigerated cavity constituted by a structural wall and a cover fixed to the structural wall by means of fixing elements defining a channel between them. The structural wall has a plurality of air baffles and at least one hole for forced reception of refrigerated air. The cover has a plurality of openings and part of the refrigerated air that comes from the orifice that is directed through the air deflectors through the channel to said cover openings. The fixing of the cover to the structural wall by means of structural fixing elements complicates its assembly.
    [0007]
    [0008] The object of the invention is to have a domestic refrigeration apparatus with a simplified and at the same time robust assembly of the cover of the refrigerated air distribution system.
    [0009] This object is achieved by means of a domestic refrigerating apparatus, which comprises an inner lining forming at least one refrigerated cavity surrounded by thermal insulation material having a channel-shaped conformation directed towards the thermal insulation material with a wall in the cavity. Parallel parallel edges and a cover to cover the channel, at least in part, which is slidably fixed to the edges in the direction of the edges by means of fixing wings arranged on the perimeter of the cover, and at least one facing flap to the channel, where the apparatus further comprises at least one interlocking element fixedly connected to the wall of the tank by means of a Cuba interlocking part and which also has a covered interlocking part in which the sliding part is connected cover flap.
    [0010] The domestic refrigerating apparatus can be a single-cavity or multi-refrigerated cavity refrigerating apparatus. The inner lining is preferably shaped plastic although it may be of other conventional materials. The refrigerated cavity can have a main form of hexahedron with five structural walls that is surrounded by thermal insulation material such as conventional PU foam in this type of apparatus and can be closed with a hinged door also thermally insulated defining the sixth structural wall of the cavity. Preferably on the bottom wall of the cavity although not necessarily, it has a channel-shaped conformation directed towards the insulation material and in a preferably vertical direction with respect to the verticality of the domestic cooling apparatus. The channel has two parallel vertical edges to which the cover is fixed by means of fixing wings that it has on its perimeter. The fixing wings are anchored at the edges by pressure but allow sliding, preferably with friction, in the vertical direction of the edges. The friction exerted is sufficient to support the weight of the cover and that it does not move downwards by its own weight. The cover, on the face facing the channel, has a flap intended to be connected with the covered interlocking part of the interlocking element that is fixed to the structural wall of the cavity inside the canal. In this way, the flap and the interlocking element are covered by the cover, invisible looking from the outside of the cavity through the open hole towards the inside of the cavity with the cover installed.
    [0011]
    [0012] The interlocking element is preferably fixed riveted to the structural wall although it can be fixed screwed or glued. The interlocking element is preferably made of plastic and has a Cuba interlocking part that crosses the structural wall towards the insulation material and that during deformation is deformed so as not to be able to cross the wall again in the opposite direction as occurs with rivet or a block. of hole being firmly attached to the wall. This known form of joint can be replaced by other conventional fixing modes. The interlocking element also has a covered interlocking part that protrudes into the cavity and is where the cover flap is connected. The method of mounting the cover is simple, first the cover faces the channel with the flap and the interlocking element not facing perpendicular to the wall, second the cover is pushed against the edges of the channel being fixed by pressure to the channel and third the cover is moved in the direction of the edges of the channel towards the interlocking element until the flap makes contact with the interlocking element.
    [0013]
    [0014] To facilitate the assembly of the interlocking element, it is advantageous that the covered interlocking part has a conical shape, so it is not necessary that it has a specific mounting position with respect to its axis of symmetry. That is, mounted in any way perpendicular to the structural wall, the flap will be connected in the same way. It could be in the form of a plate, but the truncated conical shape also guarantees an increase in contact between the flap and the covered interlocking part.
    [0015]
    [0016] This form of fixing the cover to the structural wall of the cavity is especially robust and simple to mount. By pulling the cover in a direction perpendicular to the structural wall on which it is mounted, a force greater than 50 Nm must be exerted. For a more robust fixing, two or more interlocking elements connected with respective cover flaps are provided.
    [0017]
    [0018] In a more robust embodiment, the flap is arranged on the perimeter of the cover on one side of the fixing wing. The flap is also arranged on the perimeter of the cover so that the grip force is greater when the force exerted to remove the cover is made from its center. This arrangement also makes it more convenient and simplifies the configuration of the roof that can be made as a single sheet formed on its perimeter with the fixing wing and the flap.
    [0019]
    [0020] It is envisioned that the edge of the channel has at least one shoulder towards the opposite edge and the cover fixing wing has at least one shaped edge that fits into the shoulder. This makes pressure fixing and sliding of the cover over the edges safer. It is preferable that each edge has at least one shoulder and preferably extends in the direction of the edge. The edge formed in the fixing wing covers a large part and preferably the entire length of the fixing wing. For a firmer fixation, the one in the wall inside the channel is formed a stop that limits the movement of the perimeter of the cover towards the conduit. The stop and the shoulder are preferably not arranged at the same height to prevent the fixing from being too rigid. For a better assembly, it is provided that the cover is flexible at least in part for its fixing by pressure in the channel and it also facilitates the assembly that the cover is in addition to plastic material at least in part, preferably ABS since the cover can be an aesthetic piece facing the inside of the refrigerated cavity.
    [0021] Then, the channel and the cover form an air duct for refrigerated air and the cover has at least one window for the exit of air into the refrigerated cavity. This window directs the air outlet to the required place inside the cavity. The window is usually on the front surface of the roof, but it can be made as a cutout of its perimeter. And to boost the air inside the duct, a fan that blows air into it is provided.
    [0022]
    [0023] Inside the duct an air guide is provided to direct the air from the air inlet to the channel to the window. This air guide can be formed in the structural wall or it can be one or several independent inserts. The air guide is not made of a piece with the cover or with the structural wall, it is provided that it can be fixed by pressure between the wall of the conformation and the cover. It can also be fixed attached to one of the two and adding gaskets between the guide and the wall or the cover so that the air is directed better.
