    A blender for processing edible materials includes a base with a motor, a blade assembly and a container. The blender further comprises a first safety mechanism and a second safety mechanism. The first safety mechanism works to ensure that the container is firmly attached to the blade assembly before the blade assembly can be mounted to the base. The second safety mechanism works to ensure that the motor on the base can only be started when the container and blade assembly are firmly mounted on the base. The blender is operable by attaching the container to the blade assembly and then the base assembly, in such a way that both safety mechanisms are released to allow the motor to start.

    [0001] [0001] The application claims priority and benefit from United States Provisional Patent Application No. 62 / 527,945, filed on June 30, 2017, the content of which is incorporated by reference in its entirety. FIELD OF THE INVENTION
    [0002] [0002] The present invention relates to kitchen appliances. In particular, the present invention relates to blenders and food processors having safety features. BACKGROUND OF THE INVENTION
    [0003] [0003] Kitchen appliances such as blenders and food processors are well known. Such devices are usually capable of performing numerous operations, such as mixing, joining, pulsating, spraying, chopping and cutting, which are generally referred to here as processing. Such devices can process drinks and food, generally referred to here as edible material.
    [0004] [0004] —devices for processing edible material are usually comprised of a container, a blade assembly and an engine base. For example, a typical bench top blender will have a container for storing the edible material to be processed. The blender will have a blade assembly to perform the processing operation. In standard "vertical" blenders, the blade assembly is fully affixed to the bottom of the container. The container contains an opening at the top, which is closed by a lid. The container is mounted on the base in an upright position.
    [0005] [0005] For "inverted" blenders, the blade assembly is removably attached to the opening of the container so that it also functions as a lid. With this type of blender, the container is inverted to mount the blade assembly to the base. In vertical and inverted blenders, the container and the blade assembly are mounted on the top of the base, which contains a motor that drives the blade assembly blades to process the edible material in the container.
    [0006] [0006] To operate a typical blender, a user would place edible material in the container, attach the slide assembly to close the container, and then mount the container and slide assembly to the base. The user would activate the engine, which drives the blades to process the edible material in the container. As the blades are sharp and rotate at a very high speed and with great force, there is a risk of serious injury to the user if the blade assembly is not firmly attached to the container when the engine is started.
    [0007] [0007] For example, there is a risk that the container will separate from the blade assembly if the container is not firmly attached to the blade assembly when the engine is started. If the container separates from the blade assembly when the engine is started, this would create an extreme danger as the rotating blades would be exposed. A user can suffer serious injury if he or she comes in contact with the rotating blades. Thus, it is necessary to ensure that the container is locked in the blade assembly before the engine can be started and whenever the engine is running.
    [0008] [0008] In addition, there is also a risk of serious injury if the container and blade assembly are not firmly mounted on the base when the engine is started. For example, if the container and the blade assembly are not firmly mounted to the base when the engine is started, there is a risk that both the container and the blade assembly may come out of the base, which would also be extremely dangerous because the impeller that drives the blades would be exposed and could cause injury to the user.
    [0009] [0009] To minimize these types of risks, blenders have included safety features to protect the user. It is known that a blender includes a switching means to deactivate the engine if the container is not present in the base. There are also safety mechanisms that prevent the engine from starting unless the container is correctly mounted on the base of the engine. For example, United States Patent No. 3,786,999 teaches that "the jug must be properly inserted into a base element and twisted into a locked position to allow the base, which contains a portion of the driven blade shaft, to be connected to the blender's drive shaft ". Other blenders contain safety mechanisms to prevent engine operation when the lid is not attached (for example, United States Patent No. 8,403,556), so that the blender cannot be turned on unless the lid is attached to protect the user from rotating blades.
    [0010] [0010] However, these types of security mechanisms are inadequate to minimize the dangers described above. Most blenders known in the art teach the use of a single safety mechanism to protect against a single safety concern, such as when a container is mounted incorrectly on a stand, as described in United States Patent No. 3,786,999. Today's blenders do not employ a system of redundant safety mechanisms to minimize various hazards, such as when a container is improperly attached to a blade assembly or when the blade assembly is incorrectly mounted on the motor base.
    [0011] [0011] It is an objective of the invention to provide a blender containing safety mechanisms.
    [0012] [0012] It is an objective of the invention to provide a blender with a safety mechanism to ensure that the container is firmly attached to the blade assembly.
    [0013] [0013] It is an objective of the invention to provide a blender with a safety mechanism to ensure that the blade assembly is firmly attached to the motor base.
    [0014] [0014] It is an objective of the invention to use at least two safety mechanisms to protect against different risks when the blade assembly is not correctly attached to the container or when the blade assembly is not correctly mounted on the base.
    [0015] [0015] It is still an objective of the invention that the security mechanisms work redundantly. SUMMARY OF THE INVENTION
    [0016] [0016] In accordance with the objectives of the invention, the modalities of the present invention refer to a blender. A blender is to be understood as any device capable of processing edible material. The blender according to the present invention contains coordinated safety mechanisms to prevent the blender from being switched on if the container is not properly attached to the slide assembly or if the slide assembly is not properly mounted on the base.
    [0017] [0017] The blender according to the present invention contains a first safety mechanism, which works to ensure that the container is firmly attached to the slide assembly before the slide assembly can be mounted on the base. In one embodiment, the first safety mechanism consists of a locking mechanism that prevents the blade assembly from being mounted on the base when the container is not firmly attached to the blade assembly. The locking mechanism consists of an obstruction flap or equivalent structure that can move between a locking position and an unlocking position. In the standard locking position, the locking mechanism blocks the blade assembly from being mounted to the base.
    [0018] [0018] To move the locking mechanism so that the blade assembly can be mounted on the base, it is necessary to move the obstruction flap or equivalent structure to the unlock position. This can be done using a spring-loaded flap located on the blade assembly. When the container is attached to the blade assembly, it presses the spring-loaded tab, causing the locking mechanism to move to the unlocked position to allow the blade assembly to be mounted on the motor base. In alternative embodiments of the invention, the first safety mechanism need not be composed of a spring-loaded flap or other obstructive physical components, but it can be composed of a system of electronic emitters and detectors that can detect when the container is properly attached to the mounting of blades.
    [0019] [0019] In another embodiment of the invention, the blender includes a second safety mechanism that works to ensure that the motor on the base can only be started when the container and the blade assembly are firmly attached to the base. In a preferred embodiment, the second safety mechanism consists of an emitter and a corresponding detector that communicate to activate the engine. The emitter can be a magnetic element or any sensor element capable of communicating a signal. The detector can be a magnetic element or any element capable of receiving a signal. In a preferred embodiment, the emitter is located in the slide assembly and the detector is located at the base. (On the other hand, the emitter can be on the base and the detector in the slide assembly). The transmitter communicates with the detector to activate the motor. For the emitter to communicate with the detector, the emitter must be aligned with the detector. The transmitter and detector can only be aligned when the slide assembly is mounted on the base.
    [0020] [0020] In one embodiment, the emitter in the blade assembly is attached to a spring-loaded flap that allows the second safety mechanism to move between an "off" position and an "on" position. The default position of the emitter is in the "off" position, where it is not aligned with the detector, thus preventing the emitter from communicating with the detector to activate the motor. In order to move the second safety mechanism to the "on" position to activate the motor, it is necessary to align the emitter with the detector by pressing the spring-loaded tab. The flap can only be pressed to align the emitter with the detector when the container is properly attached to the slide assembly. That is, when the container is firmly attached to the slide assembly, the container will press the spring-loaded tab to move the emitter into alignment with the detector. When the emitter is correctly aligned with the detector, the motor at the base can be started.
    [0021] [0021] In a preferred mode, the first and second security mechanisms work together. When the container is attached to the blade assembly, it will release both the first and the second safety mechanisms. Attaching the container to the slide assembly will cause the locking mechanism of the first safety mechanism to move to an unlocked position, while at the same time causing the emitter of the second safety mechanism to align with the detector on the base. With the first safety mechanism in the unlocked position, the blade assembly can be attached to the motor base. With the second safety mechanism in the "on" position, the engine can be started.
    [0022] [0022] Not only can the first and second security mechanisms work together, but they can also be redundant. For example, in a preferred mode, the engine will be automatically turned off if the container is separated from the slide assembly because the emitter will go out of alignment with the detector. This ensures that the engine can never be started if the container separates from the blade assembly or if the blade assembly separates from the base during operation.

    [0040] [0040] The invention will now be described in more detail hereinafter with reference to the accompanying drawings, in which the modalities of the invention are shown. This invention can, however, be realized in several different ways and should not be interpreted as limited to the modalities presented here. Instead, these modalities are provided for this disclosure to be thorough and complete, and to fully convey the scope of the invention to those skilled in the art.
    [0041] [0041] As shown in Figure 1, a blender 40 according to an embodiment of the invention consists of a container 10, a blade assembly 20 and a base 30. As further shown in the exploded view of Figure 2, the blade assembly 20 is removably attached to the container 10 to form an enclosed space for processing edible material. The blade assembly 20, with the container 10 attached, is removably mounted on the base 30.
    [0042] [0042] With reference now to Figure 3, the container 10 contains a body 100 with an open end 101 which is defined by an edge 102. In a preferred embodiment, the body 100 is of warhead (i.e., projectile) shape, although it may have any shape that serves the intended function of the invention. The body 100 is further defined by an outer side 103 and an inner side 104.
    [0043] [0043] To facilitate the attachment of container 10 to the slide assembly 20, container 10 contains one or more tongue protrusions 106 located on the inner side 104, close to edge 102. As described below, tongue protrusions 106 engage with grooves corresponding 214 in the blade assembly 20 to secure the container 10 to the blade assembly 20.
    [0044] [0044] Referring now to Figures 4 to 8, the blade assembly 20 is composed of a blade or blades 200, a blade holder 202 and a blade impeller 204. As shown in Figures 5 and 6, blade 200 it is mounted on blade holder 202 and connected to blade impeller 204, so that blade impeller 204 rotates blade 200.
    [0045] [0045] As best shown in Figure 4, blade holder 202 contains an inner surface 206 that extends from blade 200 and connects to a collar 208, forming a ditch 207 between the inner surface 206 and collar 208. The collar 208 contains an upper collar wall 210, as shown in Figure 4 and a lower collar edge 212, as shown in Figure 5. The shape of collar 208 is complementary to the shape of border 102 of container 10. In a preferred embodiment, the collar 208 contains a larger circumference than edge 102, so that edge 102 fits into the ditch 207 to seal the open end 101 of container 10, as shown in Figures 1 and 11. In this way, when the blade assembly is attached to the container 10, the inner surface 206 forms a closed end for the container 10.
    [0046] [0046] As further shown in Figure 4 and Figure 8, the blade holder 202 contains one or more grooves 214 on the inner surface 206 for engaging tongue protrusions 106 in container 10. In a preferred embodiment, container 10 is attached to the assembly of blades 20 by rotating the tongue protrusions 106 into the grooves 214. When tongue protrusions 106 are secured in the grooves 214, the edge 102 of the container 10 rests in the ditch 207, between the inner surface 206 and the collar 208 for seal the open end 101 of the container 10.
    [0047] [0047] Referring now to Figures 5 and 6, blade holder 202 contains a plurality of blade holder protrusions
    [0048] [0048] With reference now to Figures 14 to 17 of the base 30, the base 30 contains a motor (not shown) to drive a motor impeller 308 which is engaged with the blade impeller 204 when the blade assembly 20 is correctly assembled on base 30.
    [0049] [0049] In a preferred embodiment, as shown in Figure 14, the base 30 contains an upper surface 306 and a base body
    [0050] [0050] As shown in Figures 14 and 17, the base 30 contains one or more ramps 302 on the upper surface 306 around the motor impeller 308. In a preferred embodiment, the base 30 contains three ramps 302 equally spaced on the upper surface 306 As shown in Figures 14 and 15, each ramp 302 contains a recess 304 for receiving the blade support protrusion 216 from the blade assembly 20. The recess 304 contains a shape that is complementary to the shape of the blade support protrusion 216, so that the blade support protrusion 216 can slide into the recess 304.
    [0051] [0051] The blade assembly 20 is mounted on the base 30 by coupling the blade impeller 204 to the motor impeller 308 and by engaging the blade support protrusions 216 with the recesses 304. When the blade assembly 20 is placed in the of the base 30, the ramps 302 will guide the blade assembly 20 until the lower collar edge 212 is substantially supported on the upper surface 306, so that each blade support protrusion 216 is substantially aligned with a corresponding recess 304. A blade assembly 20 can be securely mounted to base 30 by rotating blade assembly 20 so that blade support protrusions 216 slide into recesses 304.
    [0052] [0052] With reference now to Figures 10 and 11, the blender 40 according to the present invention contains at least one first safety mechanism 220. The first safety mechanism 220 works to ensure that container 10 is firmly attached to the assembly of blades 20 before the blade assembly 20 can be mounted on the base 30.
    [0053] [0053] Referring again to Figures 5 and 6, one embodiment of the first safety mechanism 220 comprises a locking element 218. The locking element 218 is located adjacent to one of the blade support protrusions 216, as shown in Figure 9. The locking element 218 is able to move between a locking position, as shown in Figure 10, and an unlocking position, as shown in Figure 11. In the locking position shown in Figure 10, the locking element 218 works to blocking the blade support protrusion 216 from sliding into the recess 304 of the ramp 302 in order to prevent the blade assembly 20 from being mounted on the base 30.
    [0054] [0054] More particularly, the locking element 218 is connected to a first spring flap 222. The first spring flap 222 can be a spring or any other resilient material, such as a plastic polymer, which can be compressed to move the locking element
    [0055] [0055] When the first spring flap 222 is in its standard position (ie, uncompressed state), as shown in Figure 10, the locking element 218 is in the "locking" position because it is not aligned with the protrusion of blade holder 216. When container 10 is attached to the blade assembly 20, as shown in Figure 11, edge 102 presses on the first spring flap 222. Pressing the spring flap 222 causes the locking element 218 to move to the "unlock" position, where the locking element 218 is substantially aligned with the blade support protrusion 216. If the container 10 is separated from the blade assembly 20, the first spring flap 222 will return to its " block "in Figure 10.
    [0056] [0056] Thus, the blade assembly 20 can only be mounted on the base 30 by rotating the blade support protrusions 216 to the recess 304 (shown in Figures 14 and 15) when the container 10 is attached to the blade assembly 20. The blade support protrusion 216 can only enter the recess 304 when the edge 102 of the container 10 presses the first spring-loaded tab 222 to move the locking element 218 in alignment with the blade support protrusion 216. If the container 10 is separate from the blade assembly 20, the locking element 218 will return to the standard position represented by Figure 10, thereby blocking the blade support protrusion 216 from entering recess 304.
    [0057] [0057] One form of blender 40 also contains a second safety mechanism 230, as shown in Figures 12 and 13. The second safety mechanism 230 works to ensure that the motor on the base 30 can only be started when the container 10 and the assembly blades 20 are firmly mounted on the base 30.
    [0058] [0058] As shown in Figures 12 and 13, the second safety mechanism 230 consists of an emitter 232 in the blade holder 202 and a corresponding detector 310 in the base 30. The emitter 232 can be a magnet, a laser or any device similar capable of sending a signal such as a radio frequency. The second safety mechanism 230 is capable of moving between a "off" position, as shown in Figure 12, and a "on" position, as shown in Figure 13. In the "on" position, emitter 232 is aligned with the detector 310 to allow the motor at base 30 to activate. In the "off" position, emitter 232 is not aligned with detector 310, which causes the engine to be turned off.
    [0059] [0059] Referring more particularly to Figure 12, the emitter 232 is connected to a second spring-loaded flap 234 that protrudes from an opening in the ditch 207 adjacent the upper collar wall 210 of the blade holder 202. In one embodiment, the second spring flap 234 is adjacent to the first spring flap 222. The second spring flap 234 can be a spring or any other resilient material, such as a plastic polymer, which can be compressed to move between the "off" position (Figure 12) and the "on" position (Figure 13).
    [0060] [0060] Emitter 232 is able to interact with detector 310 in base 30 to activate the motor. Detector 310 is a component capable of receiving magnetic signals, optical signals or radio signals from emitter 232. For example, if emitter 232 is a magnet, detector 310 may be a corresponding magnetic switch. In the preferred embodiment, detector 310 is located at an end end of recess 304 on ramp 302, so that emitter 232 aligns with detector 310 only when the blade support protrusion 216 is fully inserted into recess 304.
    [0061] [0061] In the standard "off" position, as shown in Figure 12, detector 310 does not receive a signal from emitter 232 because emitter 232 is not aligned with detector 310. Thus, when emitter 232 is not aligned with detector 310, the motor on base 30 cannot be started. To start the engine, it is necessary to move the emitter 232 to align with detector 310, as shown in Figure 13. Emitter 232 moves to align with detector 310 when the second spring flap 234 is fully depressed. When the container 10 is mounted in the blade assembly 20, as shown in Figure 13, the edge 102 of the container 10 presses the second spring-loaded tab 234 to move the emitter 232 in alignment with the detector 310 to change the second safety mechanism 230 to the "on" position. When the second safety mechanism 230 is in the "on" position, detector 310 receives a signal from emitter 232 to activate the motor at base 30.
    [0062] [0062] If the container 10 is removed from the blade assembly 20, the second spring-loaded flap 226 will return to its standard "off" position and the emitter 232 will be out of alignment with detector 310, causing the motor to be automatically turned off.
    [0063] [0063] The first safety mechanism 220 and the second safety mechanism 230 work together and are redundant to ensure that the container 10 is properly attached to the blade assembly 20 before the motor on the base 30 can be started or remains on. For example, when the container 10 is mounted on the blade assembly 20, the edge 102 of the container 10 simultaneously presses the first spring flap 222 and the second spring flap 234. As a result, the first safety mechanism 220 will be switched to the "unlock" position and the second safety mechanism 230 will be switched to the "on" position simultaneously to activate the motor at the base
    [0064] [0064] In another embodiment of the invention, as illustrated in Figure 9, the blade assembly 20 includes at least one retractable ball 240 that protrudes from the lower collar edge 212 of the blade assembly 20. The retractable ball 240 is connected to the second flap with spring 234 on collar 208.
    [0065] [0065] When the blade assembly 20 is affixed to the base 30 by rotating the blade support protrusions 216 in the recesses 304, the retractable ball 240 slides along the upper surface 306 before coming into contact with at least one protrusion 312 on the upper surface 306, as shown in Figure 17. The protrusion is positioned on the upper surface 306, so that the retractable ball 240 contacts the protrusion 312 when the blade support protrusion 216 reaches the terminal end of the recess 304. As the retractable ball 240 passes over protrusion 312, it retracts and returns to its place, producing an audible sound, such as a "click" noise. The audible sound informs the user that the blade support protrusion 216 has reached the terminal end of the recess 304 and, therefore, a firm connection has been formed between the blade assembly 20 and the base 30. The user can confirm that the blade assembly is attached to the base 30 by the audible "click" of the retractable ball 230.
    [0066] [0066] Although illustrative embodiments of the invention have been described in detail above, it should be understood that the appended claims are intended to be interpreted to include variations of the present invention.
