Kitchen waste disposers are usually installed at the drain outlet of the household cabinet sink, which can conveniently grind the leftovers discarded by food processing and food-based kitchen waste such as leftovers into fine particles. The granular kitchen waste can be naturally discharged from the pipeline along the water flow, which can effectively prevent the sink and pipeline from being blocked, and can play a role in cleaning the environment, eliminating odors, and reducing pest harassment. The main structure of a kitchen waste disposer generally consists of a motor, a crushing chamber, a knife disc, a grinding disc, a feed port, a slag outlet, and a control panel. Among them, the motor is independently installed on the lower shell of the crushing chamber and is used to provide power and speed. At present, there are various types of motors for kitchen waste disposers on the market. Brushed DC motors or induction motors are commonly used as power, and some use brushless DC motors. The appearance design of brushless DC motors is similar to that of brushed DC motors, but they are equipped with an electronic control board assembled on the motor.

[0054] The term "plurality" used in the present application refers to two or more (including two).

[0055] Reference below Figure 1-Figure 3 A kitchen waste device 1 according to an embodiment of the present invention is described.

[0056] like Figure 1 and Figure 3 As shown, according to the kitchen waste device 1 of the first embodiment of the utility model, the kitchen waste device 1 includes: a first shell 111, a second shell 112 and a motor 11.

[0057] Among them, the second shell 112 and the first shell 111 define an accommodating space 11a, and the side of the second shell 112 away from the accommodating space 11a also has a kitchen waste crushing chamber 11b and a debris outlet 11c connected to the kitchen waste crushing chamber 11b, and the kitchen waste crushing chamber 11b is suitable for accommodating the crushing knife group 12; the motor 11 includes: a rotor assembly 113 and a stator assembly 114, and the rotor assembly 113 and the stator assembly 114 are arranged in the accommodating space 11a; the minimum distance h between the second shell 112 and the stator assembly 114 satisfies: 2.5mm≤h≤30mm.

[0058] Specifically, at least parts of the first shell 111 and the second shell 112 can be spaced apart and define an accommodating space 11a, and at least parts of the rotor assembly 113 and the stator assembly 114 can be accommodated in the accommodating space 11a. The first shell 111 and the second shell 112 can install, support and protect the rotor assembly 113, the stator assembly 114, etc. The rotor assembly 113 and the stator assembly 114 can cooperate to convert electrical energy into mechanical energy so that the motor 11 can provide power for the kitchen waste device 1; the kitchen waste crushing chamber 11b is located on the side of the second shell 112 away from the accommodating space 11a and is suitable for accommodating the crushing knife group 12, and the crushing knife group 12 can crush the food discarded by food processing in the kitchen waste crushing chamber 11b. The leftovers and kitchen waste materials such as leftovers are crushed and ground into fine debris, and the final debris can be discharged from the kitchen waste crushing chamber 11b through the debris outlet 11c to complete the processing of the kitchen waste materials, thereby effectively preventing the sink and pipe from being blocked, and can play a role in cleaning the environment, eliminating odors, and reducing pest harassment; the minimum distance h between the second shell 112 and the stator assembly 114 can be the relative direction in which at least part of the second shell 112 and the first shell 111 are separated (that is, the relative direction of the accommodating space 11a and the kitchen waste crushing chamber 11b), and the distance between the end faces of the second shell 112 and the stator assembly 114 facing each other in the relative direction is at least 2.5mm and at most 30mm.

[0059] It should be pointed out that, when the minimum distance h between the second housing 112 and the stator assembly 114 is less than 2.5 mm, it is easy to cause the stator assembly 114 to have an insufficient safety distance from the second housing 112, which poses an electrical safety risk and is not conducive to the angle design of the slag outlet 11c, which will increase the difficulty of material discharge and affect the working efficiency and effect of the kitchen waste device 1; and when h>30 mm, the increase in the accommodating space 11a will increase the overall height of the kitchen waste device 1 and occupy more cabinet space. Therefore, limiting the minimum distance h between the second housing 112 and the stator assembly 114 to within the range of 2.5 mm to 30 mm can improve the safety of the motor 11 while optimizing the volume of the kitchen waste device 1 and improving the utilization rate of the cabinet space.

[0060] According to the kitchen waste device 1 of the present invention, a storage space 11a is formed on the side of the second shell 112 facing the first shell 111, and a kitchen waste crushing chamber 11b is formed on the side of the second shell 112 away from the storage space 11a, so that the kitchen waste device 1 has a double-chamber structure, and the motor 11 shell and the kitchen waste device 1 shell can be integrated, thereby saving materials and improving the integration between components, reducing costs and weight, optimizing the volume of the kitchen waste device 1, and improving the efficiency of component assembly. In this way, the utilization rate of the cabinet space can be increased, the sink load can be reduced to extend the life of the sink, the production efficiency of the kitchen waste device 1 can be improved, and economic costs can be saved, which can effectively improve the user experience. Figure 1As shown, according to some embodiments of the present invention, the second shell 112 includes a sleeve portion 1121, the sleeve portion 1121 is located on the axis of the second shell 112, and the rotating shaft 1131 of the rotor assembly 113 passes through the sleeve portion 1121 and extends into the food waste crushing chamber 11b.

[0061] Specifically, the sleeve portion 1121 can be located on the axis of the second shell 112 and penetrate through it axially, and the rotating shaft 1131 of the rotor assembly 113 can pass through the sleeve portion 1121 and extend into the kitchen waste crushing chamber 11b, so that the rotating shaft 1131 can be connected to the crushing knife group 12 in the kitchen waste crushing chamber 11b to drive the crushing knife group 12 to work. Among them, at least part of the rotating shaft 1131 cooperates with the sleeve portion 1121, that is, the sleeve portion 1121 is sleeved on the outer periphery of at least part of the rotating shaft 1131. On the one hand, the sleeve portion 1121 can position and carry the rotating shaft 1131, which can improve the stability and reliability of the rotor assembly 113 under normal operating conditions, and the sleeve portion 1121 can also reduce the noise and vibration generated during the rotation of the rotating shaft 1131, which can effectively improve the operating efficiency of the motor 11 and optimize the noise reduction performance of the motor 11; on the other hand, the sleeve portion 1121 provides a channel for the cooperation between the rotating shaft 1131 and the crushing knife group 12, ensuring that the rotating shaft 1131 can drive the crushing knife group 12 to work normally. At the same time, it also improves the compactness of the assembly structure of the rotating shaft 1131, the crushing knife group 12 and the second shell 112, thereby further optimizing the volume and weight of the kitchen waste equipment 1, saving the layout space and material costs.

[0062] In addition, in some specific embodiments of the present invention, the crushing knife group 12 is arranged at one end of the rotating shaft 1131 which is axially away from the accommodating space 11a, and the crushing knife group 12 is connected to the rotating shaft 1131 by fasteners. This is beneficial to improve the stability of the connection between the crushing knife group 12 and the rotating shaft 1131, and is beneficial to improving the working safety and working performance of the crushing knife group 12.

[0063] In some other specific embodiments of the present invention, the crushing blade assembly 12 is connected to the rotating shaft 1131 via bolts 13, and a bolt cover 14 is provided around the head of the bolt 13 protruding from the rotating shaft 1131 to protect the connection between the crushing blade assembly 12 and the rotating shaft 1131 by the bolts 13.

[0064] like Figure 3 As shown, according to some embodiments of the present invention, the second shell 112 further includes a partition 1122, which divides the sleeve portion 1121 into an oil seal chamber 11d adjacent to the food waste crushing chamber 11b and a bearing chamber 11e adjacent to the accommodating space 11a, so as to respectively set an oil seal 115 and a bearing 116.

[0065] Specifically, the partition 1122 can be arranged on the inner wall of the sleeve portion 1121. The partition 1122 has a certain thickness in the axial direction of the sleeve portion 1121 and extends radially along the sleeve portion 1121. One side of the partition 1122 in the thickness direction can define an oil seal chamber 11d adjacent to the kitchen waste crushing chamber 11b with at least part of the sleeve portion 1121, and the other side of the partition 1122 in the thickness direction can define a bearing chamber 11e adjacent to the accommodating space 11a with another part of the sleeve portion 1121. In this way, the oil seal 115 and the bearing 116 are respectively arranged on both sides of the partition 1122 to ensure the working performance of the two. The bearing 116 can cooperate with the rotating shaft 1131 in the bearing chamber 11e to ensure the normal operation of the rotating shaft 1131. The oil seal 115 can seal, waterproof and dustproof the rotating shaft 1131, thereby improving the working safety of the rotating shaft 1131 and the rotor assembly 113 and extending their service life.

[0066] It should be noted that a through hole suitable for the rotation shaft 1131 to pass through is also formed in the middle of the partition 1122 to ensure that the rotation shaft 1131 can pass through the sleeve portion 1121 to achieve cooperation with the crushing knife group 12 in the kitchen waste crushing chamber 11b.

[0067] like Figure 3 As shown, according to some embodiments of the present invention, one radial end of the partition 1122 is connected to the sleeve portion 1121, and a flange portion 11221 is provided on the other radial end of the partition 1122. The flange portion 11221 extends toward the kitchen waste crushing chamber 11b and defines a water collecting trough 11f.

[0068] Specifically, the flange portion 11221 is arranged at one end of the partition 1122 that is away from the sleeve portion 1121 in the radial direction (i.e., the edge position of the through hole of the partition 1122) and extends toward the kitchen waste crushing chamber 11b. The flange portion 11221 has a certain thickness in the radial direction of the partition 1122. The inner side of the flange portion 11221 in the radial direction is opposite to the rotating shaft 1131, and the outer side is opposite to the sleeve portion 1121. The flange portion 11221 and the surfaces of the partition 1122 and at least part of the sleeve portion 1121 facing each other define a water collecting area. Groove 11f, so that the water collecting tank 11f and the rotating shaft 1131 can be separated by the flange portion 11221 and the partition 1122, the water collecting tank 11f can be used to collect moisture and other liquids that may enter the oil seal chamber 11d. For example, when the sealing effect of the oil seal 115 may be reduced after long-term operation and leakage may occur, the water collecting tank 11f can collect the infiltrated liquid to prevent the liquid from entering the bearing chamber 11e and the accommodating space 11a and causing a short circuit failure of the motor 11, which can effectively improve the safety and service life of the motor 11.

[0069] like Figure 1As shown, according to some embodiments of the present invention, the second shell 112 further includes a waterproof cover 1123 , and the waterproof cover 1123 is covered on the partition 1122 .

[0070] Specifically, the waterproof cover 1123 can be covered on one side of the partition 1122 close to the kitchen waste crushing chamber 11b in the thickness direction, and the waterproof cover 1123 is arranged between the partition 1122 and the oil seal 115, and the waterproof cover 1123 is connected to at least part of the outer periphery of the rotating shaft 1131. Exemplarily, the waterproof cover 1123 can be covered on at least part of the outer periphery of the rotating shaft 1131. By providing the waterproof cover 1123, on the one hand, the waterproof cover 1123 can further protect and isolate the rotating shaft 1131, and can further protect the rotating shaft 1131, the bearing 116 and other components from the intrusion of moisture and other liquids. The waterproof cover 1123 and the oil seal 115 form a double-layer waterproof structure, which can effectively improve the overall working safety of the motor 11; on the other hand, when moisture or other liquids penetrate into the oil seal chamber 11d, the outer surface of the waterproof cover 1123 (that is, the surface of the waterproof cover 1123 away from the rotating shaft 1131 in the thickness direction) can guide the liquid, thereby improving the accuracy of the liquid entering the sump 11f.

[0071] like Figure 2 As shown, according to some embodiments of the present invention, the waterproof cover 1123 includes a cover body 11231 and a side panel 11232 .

[0072] The cover body 11231 extends in the radial direction of the motor 11 , the side plate 11232 extends in the axial direction of the motor 11 and is located at the radial outer end of the cover body 11231 , and the cover body 11231 is connected to the rotating shaft 1131 of the rotor assembly 113 .

[0073] Specifically, the cover body 11231 can extend along the radial direction of the motor 11 and have a certain thickness in the axial direction of the motor 11, and the axial projection of the cover body 11231 can be constructed as a ring, and the inner wall and at least part of the surface of the ring-shaped cover body 11231 can be connected to the rotating shaft 1131; one end of the side plate 11232 in the axial direction can be connected to the radial outer end of the cover plate, and the other end extends toward the bottom wall of the water collecting tank 11f, and the side plate 11232 has a certain thickness in the radial direction of the motor 11. When moisture or other liquids penetrate into the oil seal chamber 11d, the oil seal 115 can serve as the first layer of protection, and the waterproof cover 1123 is located between the oil seal 115 and the partition 1122, which can serve as the second layer of protection. When the liquid flows into the cover body 11231, it can flow along the outer surface of the cover body 11231 (the surface of the cover body 11231 away from the partition 1122 in the thickness direction) to the outer surface of the side plate 11232 (the surface of the side plate 11232 away from the rotating shaft 1131 in the thickness direction), and the side plate 11232 extends axially toward the water collecting tank 11f, so that the liquid can eventually flow into the water collecting tank 11f along the outer surface of the side plate 11232 without affecting the normal operation of the rotating shaft 1131 and components such as the bearing 116.

[0074] In addition, in some specific embodiments of the present invention, at least part of the outer peripheral surface of the rotating shaft 1131 is recessed radially inward and formed into a clamping groove, and one end of the cover body 11231 radially away from the side plate 11232 is suitable for extending into the clamping groove to clamp the cover body 11231 with the rotating shaft 1131. In this way, it is helpful to improve the tightness and stability of the connection between the cover body 11231 and the rotating shaft 1131, and help to enhance the protective effect of the waterproof cover 1123.

[0075] In some other specific embodiments of the present invention, an arc-shaped transition section protruding away from the rotating shaft 1131 is formed between the cover body 11231 and the side plate 11232. The arc-shaped transition section can improve the smoothness of the liquid flowing from the cover body 11231 to the side plate 11232, and enhance the diversion effect of the waterproof cover 1123.

[0076] like Figure 3 As shown, according to some embodiments of the present invention, a flange portion 11221 is provided on the partition 1122, the cover body 11231 and the flange portion 11221 are axially opposite and spaced apart, and the side plate 11232 and the flange portion 11221 are radially opposite and spaced apart.

[0077] Specifically, the cover body 11231 is located on the side of the flange portion 11221 axially away from the accommodating space 11a, the cover body 11231 and the flange portion 11221 are axially opposite to and spaced apart from each other, the side plate 11232 is located on the side of the flange portion 11221 radially away from the rotating shaft 1131, the side plate 11232 and the flange portion 11221 are radially opposite to and spaced apart from each other, so that the axial projection of the cover body 11231 on the rotating shaft 1131 covers the axial projection of the flange portion 11221 on the rotating shaft 1131, and the outer edge of the cover body 11231 is radially spaced apart from the outer edge of the flange portion 11221 by a certain distance. In this way, it is ensured that the diameter of the cover body 11231 is larger than the diameter of the middle through hole of the partition 1122, which can ensure that the moisture that penetrates into the oil seal chamber 11d is blocked at the cover body 11231 and does not directly enter the bearing chamber 11e through the through hole, thereby improving the waterproof reliability of the waterproof cover 1123; and the cover body 11231 and the flange portion 11221 are arranged at intervals in the axial direction, which can protect the cover body 11231 from contacting the flange portion 11221 to generate vibration or looseness, and can effectively improve the stability of the connection between the cover body 11231 and the rotating shaft 1131.

[0078] like Figure 3 As shown, according to some embodiments of the present invention, the second shell 112 includes a bottom plate 1124 and a side plate 1125 located around the bottom plate 1124 .

[0079] Among them, the side plate 1125 helps to define the food waste crushing chamber 11b and the accommodating space 11a, the bottom plate 1124 separates the food waste crushing chamber 11b from the accommodating space 11a, a slag outlet 11c is formed on the side plate 1125, and at least a part of the bottom plate 1124 extends radially toward the slag outlet 11c.

[0080] Specifically, the side plate 1125 may include a first side plate 11251 and a second side plate 11252, the first side plate 11251 is connected to the peripheral side of the bottom plate 1124 and extends axially toward the direction close to the first shell 111, the first side plate 11251 and the bottom plate 1124 define a accommodating space 11a, the second side plate 11252 is connected to the peripheral side of the bottom plate 1124 and extends axially toward the direction away from the first shell 111, the second side plate 11252 and the bottom plate 1124 define a kitchen waste crushing chamber 11b, and a radially through-going residue outlet 11c may be formed on the second side plate 11252, and the residue outlet 11c is suitable for discharging the material in the kitchen waste crushing chamber 11b after being acted upon by the crushing knife group 12 and the water flow in the kitchen waste crushing chamber 11b. At least a portion of the bottom plate 1124 can extend radially toward the debris outlet 11c, so that the debris outlet 11c has a certain slope. On the one hand, the smoothness and discharge amount of materials from the debris outlet 11c can be improved, and the working efficiency of the kitchen waste equipment 1 can be improved; on the other hand, when the water flows along the bottom plate 1124 to the debris outlet 11c, heat exchange can be achieved with the accommodating space 11a through the bottom plate 1124, which can have a good heat dissipation and cooling effect on the internal components of the accommodating space 11a, which is beneficial to improving the operating efficiency and working reliability of the motor 11.

[0081] In addition, in some specific embodiments of the present invention, at least a portion of the bottom plate 1124 is tilted in a direction radially away from the axis toward a direction close to the first housing 111, and in the height direction of the kitchen waste device 1, the kitchen waste crushing chamber 11b is located above the bottom plate 1124, and the accommodating space 11a is located below the bottom plate 1124. When the kitchen waste device 1 is working, the material after being acted upon by the crushing knife group 12 can automatically slide down the inclined bottom plate 1124 to the slag outlet 11c under the action of gravity to ensure that the kitchen waste device 1 has good working performance.

[0082] It should be pointed out that in the utility model, the distance h between the second shell 112 and the stator assembly 114 is limited to the range of 2.5mm to 30mm, which also helps to ensure that the inclination of at least part of the bottom plate 1124 (this inclination is the angle of inclination relative to the horizontal direction) is set within an appropriate range. When h<2.5mm, the inclination will be too small, which will increase the difficulty of material discharge. Therefore, limiting the distance h between the second shell 112 and the stator assembly 114 to the range of 2.5mm to 30mm can also help to improve the discharge efficiency and effect of the kitchen waste equipment 1.

[0083] like Figure 1 As shown, according to some embodiments of the present invention, the inner diameter of the food waste crushing chamber 11b is D1, the outer diameter of the stator assembly 114 is D2, and both satisfy: 0.7≤D2 / D1≤1.0.

[0084] Specifically, when D2 / D1<0.7, the diameter of the stator assembly 114 will be too small. Under the condition of the same output power, the stator assembly 114 needs to be made thicker, so that the height of the accommodating space 11a increases, so that the motor 11 needs to occupy more cabinet space. At the same time, it also brings about an increase in weight, resulting in an increase in the sink load; when D2 / D1>1.0, the diameter of the accommodating space 11a will be larger than the diameter of the food waste crushing chamber 11b, and the food waste equipment 1 as a whole needs to be wrapped in a larger shell, which will also increase the volume and weight of the food waste equipment 1, resulting in reduced cabinet space utilization and increased load. By setting the proportional relationship between the inner diameter of the kitchen waste crushing chamber 11b and the outer diameter of the stator assembly 114 within the above range, illustratively, D2 / D1 can be equal to 0.7, 0.8, 0.9 or 1.0, etc., so that the inner diameter of the kitchen waste crushing chamber 11b and the outer diameter of the stator assembly 114 can have a suitable proportional range, which helps to optimize the volume and weight of the kitchen waste device 1, improve space utilization, save material costs, and reduce the sink load.

[0085] In addition, in some specific embodiments of the present invention, the inner diameter D1 of the kitchen waste crushing chamber 11b satisfies: 100mm≤D1≤200mm, and the outer diameter D2 of the stator assembly 114 satisfies: 100mm≤D2≤150mm. For example, when the inner diameter D1 of the kitchen waste crushing chamber 11b is configured to be 150mm, the outer diameter D2 of the stator assembly 114 can be configured to be 105mm, 120mm, 135mm or 150mm, etc.

[0086] like Figure 1 As shown, according to some embodiments of the present invention, the rotor core of the rotor assembly 113 has 2P stages, and the pole number 2P satisfies: 10≤2P≤20; the stator core of the stator assembly (114) has M slots, and the slot number M satisfies: 12≤M≤24.

[0087] Specifically, the number of stages 2P of the above-mentioned rotor core, when 2P<10, the motor 11 needs a larger volume to achieve the same torque, and when 2P>20, more magnetic poles are required, more permanent magnets are required, which will lead to increased production efficiency and cost; correspondingly, the number of slots M of the above-mentioned stator core 1121, when M<12, the number of turns per slot is large, the winding end of the stator assembly 112 is high, and the end loss is large, which affects the efficiency of the motor 11, and when M>24, the number of slots is large, the winding efficiency is slow, and the area utilization rate of each slot is low. In the utility model, the number of poles 2P satisfies: 10≤2P≤20, and the number of slots M satisfies: 12≤M≤24. For example, the number of slots can be constructed as 18 slots, and the number of stages can be preferably 16 poles or 20 poles, etc. By setting the number of poles and slot values ​​within the above-mentioned conditions, when the motor 11 outputs the same torque, the motor volume and weight can be optimized and the production cost can be saved.

[0088] like Figure 1 As shown, according to some embodiments of the present invention, the diameter of the stator core is 100 mm to 150 mm.

[0089] Specifically, the housing of the motor 11 in the present invention can be integrated with the housing of the kitchen waste equipment 1. Compared with the related art in which an independent motor 11 is set, it is necessary to increase the connection structure between the motor 11 and the kitchen waste equipment 1. The housing of the motor 11 in the present invention is integrated with the housing of the kitchen waste equipment 1, which can save the intermediate connection structure between the motor 11 and the kitchen waste equipment 1, reduce the number of components, improve assembly efficiency, and increase the diameter range of the stator assembly 114 that can be adapted to the motor 11, so that the diameter of the stator core can be set within the range of 100mm to 150mm. This is conducive to improving the lightness and thinness of the motor 11 and optimizing the motor working performance, and can further reduce the weight of the kitchen waste equipment 1 and the layout space occupied.

[0090] like Figure 1 As shown, according to some embodiments of the present invention, a ratio K of the diameter of the stator core to the thickness of the stator core satisfies: 5≤K≤15.

[0091] Specifically, since the diameter of the stator core can range from 100mm to 150mm, and the number of slots of the stator core can be set in the range of 12 to 24, by optimizing the diameter of the stator core and the number of slots, it is finally possible to achieve that the ratio K of the diameter of the stator core to the thickness of the stator core can be set in the range of 5 to 15. For example, the diameter of the stator core can be 100mm, and the thickness of the stator core is 20mm, corresponding to a ratio K of 5. The diameter of the stator core can also be 150mm, and the thickness of the stator core is 10mm, corresponding to a ratio K of 15. Compared with the related art, the K range value is about 1.7 to 4.8. In the utility model, by setting the ratio of the diameter of the stator core to the thickness of the stator core within the above range, the motor can be made lighter and thinner while outputting the same torque. In addition, in some specific embodiments of the utility model, the crushing knife group includes the following: Figure 2 The first cutter disc 121 and the second cutter disc 122 are shown, the first cutter disc 121 is connected to the rotating shaft 1131, and the second cutter disc 122 is arranged on the side of the first cutter disc 121 close to the accommodating space 11a in the axial direction and connected to the first cutter disc 121, and the first cutter disc 121 can support and limit the second cutter disc 122.

[0092] In some other specific embodiments of the present invention, the kitchen waste device 1 further includes: Figure 1 and Figure 2The third housing 15 shown in the figure has one end in the axial direction connected to one end of the second housing 112 in the axial direction away from the first housing 111, and defines a kitchen waste crushing chamber 11b, and one end of the third housing 15 in the axial direction away from the second housing 112 is formed with a feed port 15a, and the feed port 15a is used to provide a channel for kitchen waste materials to enter the kitchen waste crushing chamber. The third housing 15 can prevent the materials in the kitchen waste crushing chamber from splashing to the outside, and can ensure the normal feeding of the kitchen waste device 1.

[0093] In some further specific embodiments of the present invention, the kitchen waste device 1 further includes: Figure 1 The sealing ring 16 and the shaft sleeve 17 are shown. The sealing ring 16 is disposed between the third housing 15 and the second housing 112 to improve the airtightness of the connection between the third housing 15 and the second housing 112; the shaft sleeve 17 is sleeved on at least part of the outer circumference of the rotating shaft 1131 to optimize the fastening, heat dissipation and vibration reduction performance of the rotating shaft 1131.

[0094] In summary, the kitchen waste device 1 of the present invention comprises a first housing 111, a second housing 112 and a motor 11. The second housing 112 and the first housing 111 define a housing space 11a, and the second housing 112 further comprises a kitchen waste crushing chamber 11b and a slag outlet 11c connected to the kitchen waste crushing chamber 11b on a side away from the housing space 11a, and the rotor assembly 113 and the stator assembly 114 of the motor 11 are both disposed in the housing space 11a. By forming an accommodating space 11a on the side of the second shell 112 facing the first shell 111 and forming a kitchen waste crushing chamber 11b on the side of the second shell 112 away from the accommodating space 11a, the kitchen waste device 1 has a double-chamber structure, and the motor 11 shell and the kitchen waste device 1 shell can be integrated, so as to save materials and improve the integration between components, thereby achieving cost reduction and weight reduction, optimizing the volume of the kitchen waste device 1 and improving the efficiency of component assembly. In this way, the utilization rate of the cabinet space can be increased, the sink load can be reduced to extend the life of the sink, the production efficiency of the kitchen waste device 1 can be improved, and economic costs can be saved, which can effectively improve the user experience.
