[0004] Another example is the Chinese utility model patent "A kitchen waste treatment system" with patent number 202321652436.X and authorization announcement number CN220538788U, which includes a sink and a garbage disposer arranged under the sink, the garbage disposer includes a grinding chamber and a grinding disc arranged in the grinding chamber, the grinding chamber has a discharge port, and the discharge port is arranged below the grinding disc. It is characterized in that: a step structure is formed at the bottom of the sink, a main feeding port is opened at the top of the step structure, a feeding cover is installed on the main feeding port, and the top of the grinding chamber is installed on the main feeding port.

[0005] The control unit in the existing food waste disposer generates heat and heats up when working. If the temperature is too high, the entire food waste disposer will not be able to work and operate normally and stably. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a kitchen waste disposer in view of the current status of the prior art so that it can work and operate normally and stably.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: a kitchen waste disposer, comprising:

[0008] The casing has a crushing cover inside, the upper part of the crushing cover has a feed inlet, the lower part of the crushing cover has a discharge outlet, and the discharge outlet is connected to the outside;

[0009] A crushing element is arranged in the crushing cover and is used to crush the garbage entering from the feed inlet;

[0010] A driving mechanism is arranged in the housing and is used to drive the crushing element to work;

[0011] A control unit electrically connected to the driving mechanism is disposed inside the housing and outside the crushing cover;

[0012] Features:

[0013] It also includes a heat sink with a heat conduction function, which is arranged in the casing and below the control unit. The upper surface of the heat sink is used to support the control unit. The lower surface of the heat sink is provided with heat dissipation fins extending downward at intervals. The lower end of each heat dissipation fin is supported on the bottom wall of the casing, and the bottom wall of the casing is arranged to transfer the heat on the heat dissipation fins to the outside.

[0014] In order to enable the bottom wall of the casing to transfer the heat on the heat dissipation fins to the outside world, the bottom wall of the casing can be designed as a heat-conducting wall with a heat-conducting function, or a hole can be opened in the bottom wall of the casing to connect to the outside world. Preferably, the bottom wall of the casing is provided with heat dissipation holes that penetrate the wall thickness. The heat dissipation holes can dissipate the heat in the casing. At the same time, since the kitchen waste disposer is generally installed in a relatively humid environment such as under a sink, condensation water is easily generated inside. The design of the heat dissipation holes in the utility model can play a role in drainage and prevent condensation water from accumulating in the casing. And the structure of the heat dissipation fins in the utility model does not affect the drainage of the heat dissipation holes.

[0015] Preferably, the heat dissipation fins are arranged side by side.

[0016] Preferably, the number of the heat dissipation fins is 5-30, and the wall thickness of a single heat dissipation fin is 0.5-1.5 mm.

[0017] In the above schemes, preferably, an upper cover is further included, which has a top wall and a first side wall extending downward from the periphery of the top wall. The upper cover is arranged on the heat sink, and a closed cavity is formed between the top wall, the first side wall and the heat sink for the control unit to be arranged therein. In this way, condensation water and the like can be prevented from entering, thereby increasing the service life of the control unit.

[0018] Furthermore, the periphery of the heat sink extends upward to form a second side wall, the second side wall is located inside the first side wall and the two are restrained together in a detachable manner. Since the second side wall is located inside the first side wall, the second side wall can play a role of blocking water, further preventing condensation water from entering the cavity.

[0019] Furthermore, one side of the first side wall is provided with a socket penetrating through the wall thickness, and a plug extending outward is provided at a position corresponding to the socket on the second side wall so as to be inserted into the socket, and at the same time, the other side of the first side wall is connected to the corresponding second side wall by a first screw, so as to facilitate the disassembly and assembly of the upper cover.

[0020] In the above solution, preferably, the upper cover is located below the crushing cover, and the two are connected, so that the upper cover can absorb part of the vibration energy generated during the operation of the garbage disposer.

[0021] Preferably, the driving mechanism is arranged above the upper cover, and the bottom of the driving mechanism is spaced apart from the upper cover to form a heat dissipation gap, so as not to affect the heat dissipation of the motor.

[0022] Preferably, the upper cover and the crushing cover are connected via a second vertically arranged screw.

[0023] Preferably, the heat dissipation plate is connected to the bottom wall of the casing via a third screw.

[0024] Furthermore, a wire buckle is provided on the first side wall of the upper cover, and the power cord is fixed to the upper cover through the wire buckle and is electrically connected to the control unit.

[0025] Furthermore, an overload protector is also included, which is arranged in the cavity and fixed relative to the upper cover.

[0026] Furthermore, a connecting plate is provided below the overload protector, and the connecting plate is connected to the top wall of the upper cover via a fastener.

[0027] In the above solutions, preferably, the driving mechanism is a brushless DC motor. The brushless DC motor has the characteristics of high efficiency, energy saving and meeting the needs of intelligence. The brushless DC motor of the utility model is driven by a control unit, and the control unit achieves good heat dissipation through a heat sink.

[0028] Preferably, the control unit is supported on the upper surface of the heat dissipation plate by a component having a heat-conducting function.

[0029] Compared with the prior art, the advantages of the present invention are: the heat dissipation plate in the present invention can support the control unit, and at the same time can conduct the heat generated by the control unit through the bottom wall of the casing, thereby avoiding the control unit temperature from being too high, so that the food waste disposer can work and operate normally and stably.

[0030] That is, the heat dissipation plate of the utility model integrates the heat dissipation function and the supporting function, thereby simplifying the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] like Figures 1 to 7 As shown, a preferred embodiment of a food waste disposer of the present invention is shown, and the food waste disposer includes a housing 1, a crushing element 2, a driving mechanism 200, and a control box assembly.

[0040] Among them, Figure 1 , 2 As shown in FIG. 3 , a crushing cover 10 is provided inside the housing 1. The upper part of the crushing cover 10 has a feed port 10a, and the lower part of the crushing cover 10 has a discharge port 10b, which is connected to the outside. The bottom wall of the housing 1 is provided with heat dissipation holes 100 that penetrate the wall thickness at intervals.

[0041] The crushing element 2 is arranged in the crushing cover 10, and is used to crush the garbage entering from the feed port 10a. The crushing element 2 can adopt the existing technology, which will not be described in detail here.

[0042] The driving mechanism 200 is a brushless DC motor, which is arranged in the housing 1, and the motor axially extends into the crushing cover 10 and is transmission-connected to the crushing element 2 to drive the crushing element 2 to work.

[0043] like Figures 3 to 7 As shown, the control box assembly is arranged in the housing 1 and below the driving mechanism 200. The control box assembly includes a control unit 3, a heat sink 4, an upper cover 5 and an overload protector 7.

[0044] The control unit 3 is electrically connected to the driving mechanism 200 .

[0045] The heat sink 4 has a heat conduction function, and the upper surface of the heat sink 4 is supported by the control unit 3 (the control unit 3 is supported on the upper surface of the heat sink 4 by a component with a heat conduction function). The lower surface of the heat sink 4 is provided with heat dissipation fins 41 extending downward at intervals, and each heat dissipation fin 41 is arranged side by side, and the lower end of each heat dissipation fin 41 is supported on the bottom wall of the housing 1, so that the heat on the heat dissipation fin 41 can be discharged to the outside through the heat dissipation holes 100 on the bottom wall of the housing 1. In this embodiment, the number of heat dissipation fins 41 is 5-30 (the number of heat dissipation fins 41 can be any value between 5-30, such as 5, 10, 20, 30, etc.), and the wall thickness of a single heat dissipation fin 41 is 0.5-1.5 mm (the wall thickness of a single heat dissipation fin can be any value between 0.5-1.5 mm, such as 0.5 mm, 1 mm, 1.2 mm, 1.5 mm, etc.). At the same time, the periphery of the heat sink 4 extends upward to form a second side wall 42. The heat sink 4 is connected to the bottom wall of the housing 1 via a third screw 63 .

[0046] The upper cover 5 has a top wall 51 and a first side wall 52 extending downward from the periphery of the top wall 51. The top wall 51 is located above the heat sink 4. The first side wall 52 is located at the periphery of the second side wall 42 and the two are constrained together in a detachable manner. The through holes between the top wall 51, the first side wall 52 and the heat sink 4 of the upper cover 5 form a closed cavity for the control unit 3 to be arranged therein. In this embodiment, a socket 521 penetrating the wall thickness is provided on one side of the first side wall 52, and an insert block 421 extending outward is provided at a position corresponding to the socket 521 on the second side wall 42 so as to be inserted into the socket 521. At the same time, the other side of the first side wall 52 is connected to the corresponding second side wall 42 by a first screw 61, so that the upper cover 5 and the second side wall 42 can be detachably connected. In addition, a wire buckle 522 is provided on the first side wall 52 of the upper cover 5, and the power cord 523 is fixed to the upper cover 5 through the wire buckle 522 and is electrically connected to the control unit 3. The overload protector 7 is disposed in the cavity, and a connecting plate 71 is disposed below the overload protector 7 . The connecting plate 71 is connected to the top wall 51 of the upper cover 5 through fasteners 72 such as screws, so that the overload protector 7 is fixed relative to the upper cover 5 .

[0047] And, if Figure 3 As shown, the upper cover 5 is located below the crushing cover 10, and the upper cover 5 is connected to the crushing cover 10 by a second vertically arranged screw 62 (a vibration-damping screw). The driving mechanism 200 is partially located between the upper cover 5 and the crushing cover 10, and the bottom of the driving mechanism 200 is spaced from the upper cover 5 to form a heat dissipation gap 50, so as to ensure that the driving mechanism 200 can dissipate heat normally.

[0048] When the food waste disposer is working, the heat generated by the control unit 3 is transferred to the heat dissipation fins 41 through the heat dissipation plate 4, and then discharged to the outside through the heat dissipation holes 100 on the bottom wall of the casing. At the same time, condensation water inside the casing can also be discharged through the heat dissipation holes 100.
