Description

Technical Field

[0001] The utility model belongs to the technical field of cooking equipment, in particular to a waterproof food cooking machine. Background Art

[0002] Food processors are a common cooking device for processing food ingredients and are popular among users due to their convenience, especially food processors with a stirring function, such as wall breaking machines and soy milk machines. The food processors include a main unit and a cup body. A heating plate and a chopping mechanism are provided on the top of the main unit, and a power device for driving the chopping mechanism to rotate is provided inside the main unit. In order to prevent heat accumulation inside the main unit, a ventilation structure for heat dissipation is usually required to be provided on the main unit, and a fan is provided inside the main unit for driving air flow through the ventilation structure in and out of the main unit to take away heat. However, due to the ventilation structure, in order to prevent water from entering the main unit, the existing main unit cannot be directly rinsed, especially cannot be directly put into a dishwasher for cleaning. Therefore, food residues on the heating plate and the chopping mechanism are often not thoroughly cleaned or are difficult to clean. Therefore, it is very necessary to develop a food processor that can be directly rinsed. Utility Model Content

[0003] The utility model aims to overcome the technical deficiency of the existing food processor that the host machine cannot be directly rinsed, and to provide a food processor with a sealing member that can open or close the air inlet and the air outlet, wherein heat dissipation is achieved by opening the air inlet and the air outlet during operation, and sealing and waterproofing are achieved by closing the air inlet and the air outlet during cleaning, thereby making the cleaning of the host machine more thorough.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A waterproof food cooking machine, comprising a main machine, a cup body and a driving device, wherein the main machine and the cup body are connected to each other, the driving device is arranged on the main machine or the cup body, the cup body is provided with a cooking cavity, a stirring mechanism drivingly connected to the driving device is arranged in the cooking cavity, and the bottom of the main machine is provided with:

[0006] Air inlets and outlets;

[0007] A manual trigger component is movably connected to the host, and the manual trigger component is configured with a sealing structure for sealing the air inlet and the air outlet. The sealing structure can be driven by the manual trigger component to change its relative position with the air inlet and the air outlet to open or close the air inlet and the air outlet.

[0008] Compared with the prior art, the food cooking machine provided by the utility model sets a blocking structure at the bottom of the main unit that can open or close the air inlet and the air outlet, and changes the position of the blocking structure by manually triggering a component to realize the opening and closing of the air inlet and the air outlet. Therefore, when the air inlet and the air outlet are opened, the food cooking machine can work normally to dissipate heat, and when the air inlet and the air outlet are closed, it can be ensured that water will not enter the main unit, so it can be rinsed or even put into a dishwasher for comprehensive cleaning.

[0009] The following are two ways to set up manual trigger components:

[0010] (1) As the first setting method of manually triggering the component:

[0011] The manual trigger assembly includes a bottom cover rotatably mounted on the bottom of the main unit, the bottom cover and the main unit are sealed together, the air inlet and the air outlet are arranged as arc-shaped grooves extending along the rotation trajectory of the bottom cover, the blocking structure includes air holes arranged on the bottom cover corresponding to the air inlet and the air outlet, and a sealing strip sealing upwardly against the bottom of the main unit around the air holes, ventilation is achieved when the air holes are rotated to align with the air inlet and the air outlet, and sealing is achieved when the air holes are rotated to be offset from the air inlet and the air outlet. This setting method is simple and convenient to operate, and the air inlet and the air outlet can be opened and closed by the operator only by rotating the bottom cover.

[0012] Furthermore, a rotating shaft is fixedly connected to the middle of the bottom cover, and the rotating shaft is rotatably and sealedly connected to the bottom of the host. Preferably, the host is also configured with a bearing that cooperates with the rotating shaft, so as to improve the smoothness of the rotating shaft when rotating.

[0013] (2) As the second setting method of manually triggering the component:

[0014] The blocking structure is provided with two blocking members respectively used to seal the air inlet and the air outlet;

[0015] The manual trigger assembly includes an operating mechanism for driving at least one blocking member to rise and fall, the operating mechanism includes a driving member and a limiting structure, the driving member can move up and down relative to the main unit to drive the blocking member to rise and fall and fix the current height of the blocking member through the limiting structure, so as to open the air inlet or the air outlet when the blocking member rises.

[0016] Among them, the operating mechanism of the utility model includes the following two settings:

[0017] 1. Two operating mechanisms are provided for two blocking members respectively, and each operating mechanism controls the lifting and lowering of the corresponding blocking member respectively;

[0018] 2. The operating mechanism is provided with one for controlling the lifting and lowering of one of the blocking pieces, and the manual trigger assembly also includes a trigger protrusion arranged at the bottom of the other blocking piece and protruding from the bottom of the main unit, and the main unit is provided with a second elastic reset piece that provides a downward elastic force to the blocking piece, and when the trigger protrusion is pushed upward, the corresponding blocking piece is driven to rise to open the air inlet or the air outlet, and when the trigger protrusion is released, the blocking piece moves downward under the action of the second elastic reset piece to close the air inlet or the air outlet.

[0019] Furthermore, the limiting structure includes:

[0020] A plurality of sawtooth-shaped limit grooves with openings facing upwards are arranged in the circumferential direction, and a guide groove extending downwards is arranged between each of the limit grooves;

[0021] The rotating member is rotatably abutted against the lower end of the blocking member, the driving member is sleeved on the lower side of the rotating member, and a limiting portion is provided on its outer periphery which can be movably clamped into the guide groove up and down, and a plurality of claws are provided on the outer periphery of the rotating member which are respectively clamped into the corresponding guide grooves and placed on the upper side of the limiting portion, and the claws are wedge-fitted with the limiting portion;

[0022] a first elastic return member, providing an elastic force for the rotating member to move downward;

[0023] The driving member drives the rotating member to move upward, so that the claw moves up to the top of the limiting groove through the guide groove and compresses the first elastic return member. When the driving member is released, the first elastic return member rebounds to make the claw rotate and clamped into the limiting groove to fix the height of the blocking member to open the air inlet or the air outlet. When the driving member moves up again to compress the first elastic return member, the rotating member moves up and rotates. After releasing the driving member, the claw clamps into the guide groove, so that the blocking member moves down to seal the air inlet or the air outlet.

[0024] Furthermore, a mounting hole is provided at the bottom of the main machine, and a limit sleeve is arranged around the circumference of the mounting hole. Each of the limit grooves is composed of a first ratchet tooth and a second ratchet tooth located at the upper end of the limit sleeve. The guide groove is formed between the second ratchet tooth of a limit groove and the first ratchet tooth of an adjacent limit groove. The driving member can be movably installed up and down in the mounting hole.

[0025] Furthermore, a plurality of conical teeth are arranged around the upper end of the driving member, and the conical teeth corresponding to the guide grooves radially extend and snap into corresponding limiting grooves to form the limiting portion.

[0026] Furthermore, the operating mechanism also includes an installation sleeve covering the upper end of the limiting sleeve, the blocking member sealably passes through the installation sleeve up and down, and the first elastic reset member abuts between the top side of the installation sleeve and the upper end of the rotating member.

[0029] Furthermore, the air inlet and the air outlet are arranged at the lowest end of the main unit to achieve drainage, so as to prevent water from entering the main unit and accumulating inside the main unit and being unable to be discharged.

[0030] In the second setting method of the above-mentioned manual trigger component, since the air inlet and the air outlet are respectively controlled to open and close by different sealing parts, the sealing structures of the two are relatively independent, which facilitates repair and replacement when parts are damaged. Moreover, when the two sealing parts can be independently controlled to rise and fall, the operator can close the air inlet or the air outlet as needed, so as to clean only one side of the main unit without closing both air outlets, which is more convenient to operate. In addition, the separate control of the two sealing parts allows the operator to personally confirm whether the air inlet or the air outlet is actually opened or closed each time the sealing parts are controlled, thereby further improving the reliability of waterproofing.

[0039] A preferred specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0040] See also Figures 1 to 7 A waterproof food cooking machine comprises a main unit 1 and a cup body 2 connected to each other, and a driving device 3, wherein the above-mentioned connection includes a case where the main unit 1 and the cup body 2 are detachable or integrally structured, the cup body 2 is provided with a cooking chamber 20, the driving device 3 can be arranged on the main unit 1 or the cup body 2, and the driving device 3 of this embodiment is arranged inside the main unit 1, and a stirring assembly 4 is provided at the bottom of the cooking chamber 20, which is transmission-connected to the driving device 3, and an air inlet 11 and an air outlet 12 are arranged at the bottom of the main unit 1, and a manual trigger assembly movably connected to the main unit 1, and the manual trigger assembly is provided with a blocking structure for sealing the air inlet 11 and the air outlet 12, and the blocking structure can be driven by the manual trigger assembly to change the relative position with the air inlet 11 and the air outlet 12, so as to open or close the air inlet 11 and the air outlet 12. The air inlet 11 and the air outlet 12 are arranged at the lowest end of the main unit 1 to achieve a drainage function, so as to prevent water from entering the main unit 1 and accumulating inside the main unit 1 and being unable to be discharged.

[0041] The following are two ways to set up manual trigger components:

[0042] (1) See Figures 8 to 11 , as the first setting method of manually triggering the component:

[0043] The manual trigger assembly includes a bottom cover 7 rotatably mounted on the bottom of the main unit 1, the bottom cover 7 and the main unit 1 are sealed together, the air inlet 11 and the air outlet 12 are arranged as arc-shaped grooves extending along the rotation trajectory of the bottom cover 7, the blocking structure includes air holes 71 opened on the bottom cover 7 corresponding to the air inlet 11 and the air outlet 12, and a sealing strip 72 sealingly abutting against the bottom of the main unit 1 upward around the air hole 71, ventilation is achieved when the air hole 71 is rotated to align with the air inlet 11 and the air outlet 12, and sealing is achieved when the air hole 71 is rotated to be offset from the air inlet 11 and the air outlet 12. This setting method is simple and convenient to operate, and the operator only needs to rotate the bottom cover 7 to open and close the air inlet and the air outlet.

[0044] See also Fig. 9 and Fig.11A rotating shaft 73 is fixedly connected to the middle of the bottom cover 7, and the rotating shaft 73 is rotatably and sealedly connected to the bottom of the host 1. Preferably, the host 1 is also equipped with a bearing (not shown) that cooperates with the rotating shaft 73, so as to improve the smoothness of the rotation of the rotating shaft 73.

[0045] See also Fig.10 and Fig.11 As a specific implementation, a sealing ring 74 is provided at the upper end of the bottom cover, and the sealing strip 72 and the sealing ring are integrally formed on the bottom cover 7 by secondary injection molding.

[0046] (2) As the second setting method of manually triggering the component:

[0047] See also Figures 1 to 7 The blocking structure is provided with two blocking members 5 for sealing the air inlet 11 and the air outlet 12 respectively. The manual trigger assembly includes an operating mechanism 6 for driving at least one blocking member 5 to rise and fall. For the lifting and falling of the above-mentioned blocking member 5, the utility model has two setting modes:

[0048] First, two operating mechanisms 6 are provided corresponding to the two blocking members 5 , and each operating mechanism 6 controls the lifting and lowering of a corresponding blocking member 5 .

[0049] Secondly, the operating mechanism 6 is provided with one for controlling the lifting and lowering of one of the blocking members 5, for example, only for controlling the blocking member 5 corresponding to the air inlet 11, or only for controlling the blocking member 5 corresponding to the air outlet 12, while the blocking member 5 of the other air outlet is controlled by other mechanisms, for example, see Figure 4 and Figure 7 The manual trigger assembly also includes a trigger protrusion 51 arranged at the bottom of another blocking member 5 and protruding from the bottom of the host 1. The host 1 is configured with a second elastic reset member 52 that provides a downward elastic force to the blocking member 5. When the trigger protrusion 51 is pushed upward, the corresponding blocking member 5 is driven to rise to open the air inlet 11 or the air outlet 12. When the trigger protrusion 51 is released, the blocking member 5 moves downward to close the air inlet 11 or the air outlet 12 under the action of the second elastic reset member 52. When the host 1 is placed on a placement surface, the placement surface will push the trigger protrusion 51 upward, thereby driving the blocking member 5 to rise, thereby automatically opening the corresponding air outlet. After the host 1 is picked up, the trigger protrusion 51 will move downward and reset to re-close the corresponding air outlet under the action of the second elastic reset member 52. The operation is very convenient. Of course, the opening and closing method of the blocking member 5 corresponding to the above-mentioned air outlet is not limited to the above-mentioned method of setting the trigger protrusion 51.

[0050] See also Figures 2 to 6 , the structure of the operating mechanism 6 is described below.

[0051] The operating mechanism 6 includes a driving member 61 and a limiting structure. The driving member 61 can move up and down relative to the main unit 1 to drive the blocking member 5 to rise and fall and fix the current height of the blocking member 5 through the limiting structure, thereby opening the air inlet 11 or the air outlet 12 when the blocking member 5 rises.

[0052] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 As a specific implementation, the limiting structure includes a plurality of serrated limiting grooves 620, a rotating member 65 and a first elastic reset member 63. The plurality of serrated limiting grooves 620 are circumferentially arranged and open upward. A guide groove 64 extending downward is provided between each of the limiting grooves 620. The rotating member 65 can rotatably abut against the lower end of the blocking member 5. The driving member 61 is sleeved on the lower side of the rotating member 65. A limiting portion 611 which can be movably inserted into the guide groove 64 up and down is provided on its outer periphery. A plurality of claws 651 which are respectively inserted into the corresponding guide grooves 64 and are arranged on the upper side of the limiting portion 611 are provided on the outer periphery of the rotating member 65. The claws 651 are wedge-fitted with the limiting portion 611. The first elastic reset member 63 provides an elastic force for the rotating member 65 to move downward.

[0053] The driving member 61 drives the rotating member 65 to move upward, so that the claw 651 moves upward to the top of the limiting groove 620 through the guide groove 64 and compresses the first elastic reset member 63. When the driving member 61 is released, the first elastic reset member 63 rebounds to make the claw 651 rotate and snap into the limiting groove 620, so as to fix the height of the blocking member 5 to open the air inlet 11 or the air outlet 12. When the driving member 61 moves upward again to compress the first elastic reset member 63, the rotating member 65 moves upward and rotates. After the driving member 61 is released, the claw 651 snaps into the guide groove 64, so that the blocking member 5 moves downward to seal the air inlet 11 or the air outlet 12.

[0054] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 The main unit 1 has a mounting hole 13 at the bottom, and a limiting sleeve 14 is arranged around the mounting hole 13. Each limiting groove 620 is composed of a first ratchet tooth 141 and a second ratchet tooth 142 located at the upper end of the limiting sleeve 14. The guide groove 64 is formed between the second ratchet tooth 142 of a limiting groove 620 and the first ratchet tooth 141 of an adjacent limiting groove 620. The driving member 61 can be movably installed in the mounting hole 13 up and down.

[0055] See also Figure 3The upper end of the driving member 61 is provided with a plurality of conical teeth 612 , and the conical teeth 612 corresponding to the guide grooves 64 radially extend and snap into the corresponding limiting grooves 620 to form the limiting portion 611 .

[0056] See also Figure 3 , Figure 5 and Figure 6 The operating mechanism 6 also includes a mounting sleeve 66 covering the upper end of the limiting sleeve 14, the blocking member 5 seals through the mounting sleeve 66 up and down, and the first elastic reset member 63 abuts between the top side of the mounting sleeve 66 and the upper end of the rotating member 65.

[0057] See also Figure 5 and Figure 6 The bottom of the host 1 is provided with a side edge 15 around the outer periphery of the limiting sleeve 14, the air inlet 11 or the air outlet 12 is opened between the side edge 15 and the limiting sleeve 14, and the surrounding side ring of the mounting sleeve 66 is provided with an air ring 67 connected to the upper end of the side edge 15, and the air ring 67 and the side edge 15 form an air duct, and the air ring 67 is provided with a breathable structure 671 connected to the air duct, and the blocking member 5 is provided with a plug 53 for sealing the breathable structure 671.

[0058] Alternatively, the air inlet 11 or the air outlet 12 is opened at the upper end of the mounting sleeve 66 , and the blocking member 5 is provided with a plug 53 located above the mounting sleeve 66 for blocking the air inlet 11 or the air outlet 12 .

[0059] See also Figure 5 As an improved solution, the bottom surface of the driving member 61 is provided with an arc surface 613 with a middle portion concave upward.

[0060] As another specific implementation of the above-mentioned operating mechanism 6 (this implementation is not shown in the figure), the limiting structure includes a thread arranged on the main unit 1, and the driving member 61 is threadedly connected to the main unit 1 through the limiting structure. The blocking member 5 is driven to rise and fall by rotating the driving member 61 to open or close the air inlet 11 or the air outlet 12.

[0061] Compared with the prior art, the food cooking machine provided by the utility model sets a blocking structure at the bottom of the main unit 1 that can open or close the air inlet 11 and the air outlet 12, and changes the position of the blocking structure by manually triggering a component to realize the opening and closing of the air inlet 11 and the air outlet 12. Therefore, when the air inlet 11 and the air outlet 12 are opened, the food cooking machine can work normally to achieve heat dissipation, and when the air inlet 11 and the air outlet 12 are closed, it can be ensured that water will not enter the main unit 1, so it can be rinsed or even put into a dishwasher for comprehensive cleaning, which effectively improves the cleaning effect.

[0062] In particular, for the second setting of the manual trigger component, since the air inlet 11 and the air outlet 12 are respectively controlled to open and close by different sealing members 5, the sealing structures of the two are relatively independent, which facilitates maintenance and replacement when parts are damaged. Moreover, when the two sealing members 5 can be independently controlled to rise and fall, the operator can close the air inlet 11 or the air outlet 12 as needed, so as to clean only one side of the main unit 1 without closing both air outlets, which makes the operation more convenient. In addition, the separate control of the two sealing members 5 allows the operator to personally confirm whether the air inlet 11 or the air outlet 12 is truly opened or closed each time the sealing member 5 is controlled, thereby further improving the reliability of waterproofing.

[0063] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
