Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food waste disposal, and particularly relates to a double-layer motor end cover and a food waste disposer. BACKGROUND

[0002] With the improvement of living standards, electrical appliances have been popular in every family, especially food waste disposers, which are convenient to use and have been widely used in our life. In daily life, kitchen waste accounts for a considerable proportion in household garbage, such as melon rind, peel, leftover food and the like. These kitchen wastes are prone to rot, produce odor and breed bacteria, which will bring certain influence on the living environment and health of the family.

[0003] The existing food waste disposer has a motor front end cover located below a grinding part. A top of a body of the motor front end cover forms a discharge bin. A side wall of the discharge bin is provided with a drain hole. In addition, a center of the motor front end cover is provided with a through hole. A motor shaft penetrates the through hole to drive a grinding mechanism above the motor front end cover to move. Food waste is discharged through the drain hole of the discharge bin after being ground by the grinding mechanism of the grinding part.

[0004] At present, the existing motor front end cover has the following defects:

[0005] (1) The motor front end cover is made of metal material. The entire motor front end cover is an integral structure. The discharge bin and the drain hole are also made of metal material. After long-term contact with food waste, the surface of the discharge bin and the drain hole is prone to rust and oxidation. Even bacteria may breed in the discharge bin. After a long time, a stone layer may be formed in the discharge bin, so that food waste residues cannot be discharged in time. Moreover, the stone layer is corrosive. After a long time, the metal material motor end cover may be corroded, even perforated, so that the motor end cover may appear water seepage or leakage.

[0006] (2) There is a gap between the through hole of the motor front end cover and the motor shaft. Although a waterproof structure is arranged on the motor shaft, the components of the waterproof structure may be worn to a certain extent after long-time operation of the motor. Therefore, if there is a lot of water near the motor shaft and the water cannot be discharged in time, the water that cannot be discharged in time may seep into the through hole along the gap between the through hole and the motor shaft and reach the motor, the circuit board or other metal components, so that the motor may be burned, the circuit board may be short-circuited or the metal components may be rusted due to water seepage. SUMMARY

[0007] An object of the present application is to provide a double-layer motor end cover, which can solve the problem that the motor end cover of a food waste disposer is made of all metal and is prone to rust or the problem that the motor end cover is made of all plastic and has low strength.

[0008] Another objective of this invention is to provide a food waste disposer that solves the problem of easy rusting caused by the motor end cover being made entirely of metal or low strength caused by the motor end cover being made entirely of plastic.

[0009] To achieve this objective, the present invention adopts the following technical solution:

[0019] Specifically, when the clearance notch is a through groove opened from top to bottom on the outer peripheral sidewall of the end cap body, the material hopper is easier to enter and the assembly efficiency is higher because the top of the through groove is open.

[0020] As a preferred technical solution, when the clearance notch is a through hole, the upper edge of the clearance notch abuts the top of the drain outlet.

[0021] Specifically, the upper edge of the clearance notch abuts against the top of the drain outlet, which can lock the drain outlet and improve the connection reliability between the feeding bin and the end cover body.

[0022] As a preferred technical solution, in the state where the clearance notch is a through groove, a fixing plate is provided on the top of the sewage outlet, and the fixing plate is fixedly connected to the end cover body.

[0026] Preferably, the first settling tank is inclined downward along the direction from the center to the outer peripheral sidewall.

[0027] Preferably, the second settling trough is inclined downwards along the direction from the center to the outer peripheral sidewall, so that food waste can enter the drain outlet more smoothly.

[0028] As a preferred technical solution, the outer peripheral sidewall of the feeding hopper is provided with a support plate, and the top of the support plate is provided with a sealing ring. The sealing ring is used to seal the gap between the outer peripheral sidewall of the feeding hopper and the inner side of the outer peripheral sidewall of the end cover body.

[0029] Specifically, by setting the sealing ring, liquid can be prevented from entering the gap between the feed hopper and the end cover body, thereby preventing liquid from reaching the motor below, effectively solving the water leakage problem and improving product reliability.

[0033] Specifically, the central part is made of metal, which can improve the accuracy of the motor shaft passing through the central part and improve the support strength of the central part; furthermore, the outer periphery is made of plastic, which can better solve the problem of bacteria growth and rust after the end cap body comes into contact with sewage.

[0034] As a preferred technical solution, a second through hole is provided at the center of the feeding bin. The second through hole has a structure that is wider at the bottom and narrower at the top, and the motor shaft passes through the second through hole.

[0035] Preferably, an oil seal component is provided between the motor shaft and the second through hole. The oil seal component is sleeved on the outer circumference of the motor shaft, and the outer circumferential sidewall of the oil seal component is matched with the inner circumference of the second through hole. The bottom-wide and top-narrow structure of the second through hole facilitates the fixing of the oil seal component.

[0036] To improve the waterproof performance of the double-layer motor end cover and overcome the potential water leakage problem between the motor end cover and the motor shaft, the following technical solution is also provided.

[0037] As a preferred technical solution, the feeding hopper is made of antibacterial plastic.

[0038] Preferably, the antibacterial plastic includes any one of natural antibacterial agents, organic antibacterial agents, or inorganic antibacterial agents.

The groove is located in the middle of the end cap body, and a first through hole is provided at the bottom center of the groove. The motor shaft passes through the first through hole. The groove is used to accommodate an oil-absorbing component, and the drainage structure is used to drain the liquid in the groove to the outer peripheral sidewall of the end cap body.

[0040] Specifically, the oil-absorbing element in the groove can absorb lubricating oil, and the motor shaft passes through the oil-absorbing element. The oil-absorbing element is used to lubricate moving parts such as the motor shaft to increase the service life of the moving parts.

[0041] Specifically, by setting the drainage structure, the liquid that has seeped into the groove can be discharged to the outer peripheral sidewall of the end cover body in a timely manner, preventing the liquid from accumulating and seeping into the motor through the first through hole, thus more reliably ensuring the motor is isolated from the liquid and preventing motor damage. This design can effectively improve the waterproof performance of the double-layer motor end cover and overcome the problem of water seepage between the end cover body and the motor shaft.

[0042] As a preferred technical solution, the drainage structure includes a drainage channel, which is a drainage trough. The inlet of the drainage trough is connected to the groove, and the outlet of the drainage trough is located in the first settling trough.

[0043] Alternatively, the drainage channel is a drainage trough, the inlet of which is connected to the groove, and the outlet of which is located on the outer side wall of the end cap body;

[0044] Alternatively, the drainage channel is a drainage hole, with the inlet of the drainage hole located at the bottom of the groove and the outlet of the drainage hole located in the first settling trough;

[0045] Alternatively, the drainage channel is a drainage hole, with the inlet of the drainage hole located at the bottom of the groove and the outlet of the drainage hole located on the outer side wall of the end cap body.

[0046] As a preferred technical solution, the drainage structure further includes an annular groove disposed at the bottom of the groove, the annular groove surrounding the outer periphery of the first through hole, the annular groove being used to collect liquid seeping into the groove, and the annular groove communicating with the drainage channel.

[0047] On the other hand, a food waste disposer is disclosed, which includes the aforementioned double-layer motor end cap.

[0048] The beneficial effects of this invention are as follows: It provides a double-layer motor end cap and a food waste disposer. The double-layer motor end cap includes an end cap body and a feeding bin made of plastic that is attached to the top of the end cap body. Through the end cap body and the feeding bin attached to the top of the end cap body, it solves the problems of easy rusting caused by using all-metal motor end caps or low strength caused by using all-plastic motor end caps in food waste disposers. The feeding bin is detachably connected to the end cap body. A drain port is provided on the outer peripheral sidewall of the feeding bin, and a clearance notch is provided on the outer peripheral sidewall of the end cap body. By placing the drain outlet in the material feeding hopper, the assembly difficulty of the material feeding hopper and the end cap body can be reduced, production efficiency can be improved, and the direct connection between the drain pipe connector and the end cap body can be avoided, which helps to omit the sealing structure of the connection between the two, thereby simplifying the overall structure; when the clearance notch is a through groove opened from the top to the bottom on the outer peripheral sidewall of the end cap body, the material feeding hopper is easier to enter and the assembly efficiency is higher because the top of the through groove is open; the end cap body is provided with a groove and a drainage structure, and the groove is located in the middle of the end cap body, The drainage structure includes a drainage channel and an annular groove at the bottom of the groove. The annular groove collects liquid that seeps into the groove and is connected to the drainage channel. The drainage channel discharges the liquid in the annular groove to the outer peripheral wall of the end cap body, preventing liquid from accumulating in the groove and seeping into the motor. A first through hole is provided at the center of the bottom of the groove, through which the motor shaft passes. The motor shaft is lubricated by an oil-absorbing component in the groove, improving the service life of the moving parts. An oil seal is provided between the motor shaft and the second through hole. The second through hole utilizes its wider bottom and narrower top structure to facilitate the fixing of the oil seal and prevent liquid from entering the second through hole. The central part is made of metal, which improves the accuracy of the motor shaft passing through the central part and increases the support strength of the central part. Furthermore, the outer peripheral part is made of plastic, which better solves the problem of bacterial growth and rust after the end cap body comes into contact with sewage. A support plate and a convex ring are provided on the outer peripheral wall of the discharge bin to support and fix the sealing ring. The sealing ring prevents liquid from seeping into the gap between the discharge bin and the end cap body, resulting in better sealing. Attached Figure Description

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0070] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0071] Example 1:

[0072] like Figures 1 to 6The illustration shows a double-layer motor end cap, comprising an end cap body 1 and a feeding bin 2 attached to the top of the end cap body 1. The feeding bin 2 is supported by the end cap body 1 and is used to collect food waste. Further, the feeding bin 2 is detachably connected to the end cap body 1. The feeding bin 2 is made of plastic, and the end cap body 1 is made of metal. Preferably, the feeding bin 2 is made of antibacterial plastic; specifically, the antibacterial plastic includes any one of natural antibacterial agents, organic antibacterial agents, or inorganic antibacterial agents. That is, the antibacterial plastic is obtained by adding a small amount of the natural antibacterial agent, organic antibacterial agent, or inorganic antibacterial agent during the manufacturing process of ordinary plastics. In this embodiment, the antibacterial plastic is preferably made of an inorganic antibacterial agent. Among inorganic antibacterial agents, silver-zinc based inorganic antibacterial agents are preferred because they have strong antibacterial ability, long antibacterial effect, good safety, high stability, strong heat resistance, and are suitable for plastic processing technology.

[0073] In this embodiment, the motor end cover is divided into two layers: a metal end cover body 1 and a plastic feeding bin 2. This effectively solves the problems of existing metal motor end covers, such as easy rusting, oxidation, corrosion, and even bacterial growth. To better prevent bacterial growth on the surface of the feeding bin 2, the feeding bin 2 is made of antibacterial plastic with a silver-zinc inorganic antibacterial agent. This effectively solves the problem of existing motor end covers easily breeding bacteria and forming a stone layer, leading to food waste residue and poor drainage, or effectively solving the problem of residual food waste and bacteria causing odor.

[0074] In this embodiment, the end cap body 1 is integrally formed, which can reduce costs and improve support strength.

[0075] In other embodiments, the feeding bin 2 is integrally formed with the end cap body 1, which reduces costs and increases support strength.

[0076] In this embodiment, the outer peripheral sidewall of the feeding bin 2 is provided with a drain outlet 21, and the outer peripheral sidewall of the end cap body 1 is provided with a clearance notch 11, through which the drain outlet 21 penetrates; further, the feeding bin 2 is provided with a receiving cavity 26, and the drain outlet 21 communicates with the receiving cavity 26; the end cap body 1 is provided with a clearance cavity 18, and the clearance notch 11 communicates with the clearance cavity 18, and the feeding bin 2 is located within the clearance cavity 18; further, the clearance notch 11 is a through hole horizontally penetrating the outer peripheral sidewall of the end cap body 1; or, the clearance notch 11 is a through groove opened from the top downwards on the outer peripheral sidewall of the end cap body 1, the through groove horizontally penetrating the outer peripheral sidewall of the end cap body 1, such as...Figure 2 As shown. The end cap body 1 and the feeding bin 2 attached to the top of the end cap body 1 solve the problems of easy rusting caused by an all-metal motor end cap in food waste disposers or low strength caused by an all-plastic motor end cap. By placing the drain outlet 21 in the feeding bin 2, the assembly difficulty of the feeding bin 2 and the end cap body 1 can be reduced, production efficiency can be improved, and the direct connection between the drain pipe connector and the end cap body can be avoided, which helps to omit the sealing structure connecting the two, thus simplifying the overall structure. Furthermore, when the clearance notch 11 is a through groove opened from top to bottom on the outer peripheral sidewall of the end cap body 1, the feeding bin 2 is easier to enter and the assembly efficiency is higher because the top of the through groove is open.

[0077] With the clearance notch 11 being a through hole, the upper edge of the clearance notch 11 abuts against the top of the drain outlet 21, such as... Figure 6 As shown. Specifically, the upper edge of the clearance notch 11 abuts against the top of the drain outlet 21, which can secure the drain outlet 21 and improve the connection reliability between the feeding bin 2 and the end cover body 1. In this embodiment, the drain outlet 21 is designed with a circular cross-section. In other embodiments, the cross-section of the drain outlet 21 can be elliptical to allow the drain outlet to pass through the clearance notch more easily. Of course, the shape of the clearance notch is also changed to elliptical accordingly. Designing the cross-section of the drain outlet 21 to be elliptical can reduce the height of the drain outlet, making it easier to fit the drain outlet into the clearance notch when installing the feeding bin.

[0078] With the clearance notch 11 being a through groove, a fixing plate 27 is provided on the top of the drain outlet 21. The fixing plate 27 is fixedly connected to the end cap body 1. In this embodiment, the fixing plate 27 and the end cap body 1 are fixedly connected in a detachable manner. Preferably, a screw-fixed detachable connection is used. Specifically, fixing holes are provided at both ends of the fixing plate 27, and screw holes that match the fixing holes of the fixing plate 27 are provided on both sides of the clearance notch 11. Finally, the fixing plate 27 is detachably fixed to the end cap body 1 using screws. Figure 13 As shown. By setting the fixing plate 27, the connection reliability between the discharge hopper 2 and the end cover body 1 can be improved, avoiding unnecessary vibration during operation. Of course, the fixing plate 27 can be fixedly connected to the end cover body 1 in other ways, such as a detachable fixing connection or a non-detachable fixing connection. In addition, the fixing plate 27 can be an integral structure with the drain outlet 21, or it can be a separate structure, that is, the fixing plate 27 is an independent component.

[0079] In this embodiment, a second settling trough 22 is provided on the top side of the feeding hopper 2. The second settling trough 22 is used to collect food waste and is connected to the drain outlet 21. A first settling trough 12 is provided on the top side of the end cap body 1. The first settling trough 12 is used to provide clearance for the second settling trough 22 and is connected to the clearance notch 11. Furthermore, the first settling trough 12 is inclined downward along the direction from the center to the outer peripheral sidewall. Furthermore, the second settling trough 22 is inclined downward along the direction from the center to the outer peripheral sidewall so that food waste can be discharged more smoothly from the second settling trough 22 through the drain outlet 21.

[0080] In this embodiment, the end cap body 1 is provided with a groove 13 and a drainage structure. The groove 13 is located in the middle of the end cap body 1, and a first through hole 19 is provided at the bottom center of the groove 13. The motor shaft passes through the first through hole 19. The groove 13 is used to accommodate an oil-absorbing component, and the drainage structure is used to drain the liquid in the groove 13 to the outer peripheral sidewall of the end cap body 1. By providing the drainage structure, the liquid that has seeped into the groove 13 can be drained to the outer peripheral sidewall of the end cap body 1 in a timely manner, preventing liquid accumulation and seepage from the first through hole 19 to the motor, thus more reliably ensuring the motor is isolated from the liquid and preventing motor damage. Furthermore, the oil-absorbing component in the groove 13 can absorb lubricating oil, and the motor shaft passes through the oil-absorbing component. This oil-absorbing component is used to lubricate moving parts such as the motor shaft to increase the service life of the moving parts.

[0081] In this embodiment, the drainage structure includes a drainage channel, which is a drainage trough 141. The inlet of the drainage trough 141 is connected to the groove 13, and the outlet of the drainage trough 141 is located within the first settling trough 12. Figure 2 As shown; in other embodiments, the drainage channel is a drainage groove 141, the inlet of the drainage groove 141 is connected to the groove 13, and the outlet of the drainage groove 141 is located on the outer side wall of the end cap body 1; or, the drainage channel is a drainage hole 142, the inlet of the drainage hole 142 is located at the bottom of the groove 13, and the outlet of the drainage hole 142 is located in the first settling groove 12, as shown. Figure 7 As shown; or, the drainage channel is a drainage hole 142, the inlet of the drainage hole 142 is located at the bottom of the groove 13, and the outlet of the drainage hole 142 is located on the outer side wall of the end cap body 1, as shown. Figures 8 to 9 As shown. In this embodiment, the drainage structure further includes an annular groove 15 disposed at the bottom of the groove 13, the annular groove 15 being used to collect liquid seeping into the groove 13, and the annular groove 15 being in communication with the drainage channel.

[0082] In this embodiment, the inlet horizontal plane of the drainage trough 141 is higher than the outlet horizontal plane of the drainage trough 141; or, the inlet horizontal plane of the drainage trough 141 is the same as the outlet horizontal plane of the drainage trough 141. In this embodiment, there are two drainage troughs 141, which are respectively arranged on both sides of the circumference of the first settling tank 12. In practice, the number and position of the drainage troughs 141 can be set according to actual needs. For example, the number of drainage troughs can be one, three or even more. In addition, the drainage troughs 141 can also be arranged on the side wall of the first settling tank 12, etc.

[0083] In other embodiments, such as Figures 7 to 9 The double-layer motor end cover shown has an inlet horizontal plane height of the drain hole 142 that is higher than the outlet horizontal plane height of the drain hole 142; or, the inlet horizontal plane height of the drain hole 142 is the same as the outlet horizontal plane height of the drain hole 142; the position of the inlet and outlet of the drain hole 142 relative to the first settling tank 12 does not affect the drainage function.

[0084] In this embodiment, a second through hole 23 is provided at the center of the feeding bin 2. The second through hole 23 has a structure that is wider at the bottom and narrower at the top, and the motor shaft passes through the second through hole 23. Further, an oil seal component is provided between the motor shaft and the second through hole 23. The oil seal component is sleeved on the outer circumference of the motor shaft, and the outer circumferential sidewall of the oil seal component is matched with the inner circumference of the second through hole 23. The second through hole 23 uses its own structure that is wider at the bottom and narrower at the top to facilitate the fixing of the oil seal component.

[0085] In this embodiment, a support plate 24 is provided on the outer peripheral sidewall of the feeding hopper 2. The support plate 24 is used to support the sealing ring, and the sealing ring is used to seal the gap between the outer peripheral sidewall of the feeding hopper 2 and the inner sidewall of the outer peripheral sidewall of the end cap body 1. Specifically, by providing the sealing ring, liquid can be prevented from entering the gap between the feeding hopper 2 and the end cap body 1, thereby preventing liquid from reaching the motor below, effectively solving the water leakage problem and improving product reliability.

[0086] In this embodiment, a raised ring 25 is provided on the outer peripheral sidewall of the feeding hopper 2. The raised ring 25 is located on the inner side of the top of the pallet 24, and the sealing ring is located on the outer side of the raised ring 25. By providing the raised ring 25, deformation and misalignment of the sealing ring after compression can be avoided, thereby ensuring the sealing effect of the sealing ring.

[0087] In this embodiment, the drain outlet 21 is connected to a drain pipe connector 3, which is used to connect to an external drain pipe. The drain pipe connector 3 is detachably installed on the drain outlet 21, such as... Figure 1As shown, a sealing ring is provided between the sewage pipe connector 3 and the discharge bin 2 to improve the sealing performance of the connection between the sewage pipe connector 3 and the discharge bin 2. The sewage pipe connector 3 and the discharge bin 2 are connected by bolts to improve assembly efficiency. By directly setting an interface that matches the connection port of the sewage pipe connector 3 at the sewage outlet 21, the problem of needing to add waterproof soft rubber, snap rings, and other components when connecting the sewage outlet and the sewage pipe connector in the prior art can be solved. The installation structure is more convenient and less expensive than the existing technology. In addition, the sewage pipe connector 3 is directly connected to the sewage outlet 21 set on the discharge bin 2, which can also solve the problems of easy damage, difficulty in waterproofing, and easy rusting when the sewage outlet is set on the metal end cap body.

[0088] The drain pipe connector 3 can be a tee pipe, a four-way pipe, a two-way pipe, or even a straight pipe, etc. In this embodiment, a four-way pipe is preferred. When the four-way pipe is connected to the drain outlet 21, the original snap ring, soft rubber and other parts can be eliminated, and the four-way pipe can be directly used to connect to the drain outlet. This not only saves snap ring, soft rubber and other parts, but also makes the connection between the drain outlet 21 and the four-way pipe more convenient.

[0089] In other embodiments, the sewage pipe connector 3 is directly installed at the sewage outlet 21 to improve assembly efficiency and waterproof performance.

[0091] like Figure 10 As shown, the design of the double-layer motor end cap differs from that of the end cap body 1 in Embodiment 1, which features a clearance cavity 18 and a material discharge bin 2 embedded within the clearance cavity 18. Figure 10 The feeding hopper 2 has an inverted structure. The outer peripheral sidewall of the feeding hopper 2 extends downward and is formed. The middle part of the end cap body 1 protrudes upward. The feeding hopper 2 covers the end cap body 1, and the outer peripheral sidewall of the feeding hopper 2 surrounds the outer side of the protrusion in the middle part of the end cap body 1.

[0092] In this embodiment, the bottom of the end cap body 1 is provided with a receiving groove 10, and the bottom end of the outer peripheral side wall of the feeding bin 2 is provided with a flange 28. When the feeding bin 2 is covered on the end cap body 1, the flange 28 is pressed into the receiving groove 10. In addition, a sealing ring (not shown in the figure) is also provided on the flange 28 to enhance the sealing between the two components.

[0093] In this embodiment, the end cap body 1 can adopt the drainage structure described in Embodiment 1, such as the drainage channel being a drainage trough as in Embodiment 1, or the drainage channel being a drainage hole as in Embodiment 1. Since the shape and structure of the end cap body 1 and the discharge bin 2 in this embodiment have changed somewhat from those in Embodiment 1, the position of the drainage trough or the position of the drainage hole in the drainage structure can be adjusted accordingly to facilitate drainage.

[0094] Example 3:

[0095] Based on Embodiment 1 or Embodiment 2, the structure of the end cap body 1 can be optimized. For example, the end cap body 1 can be made of two different materials: the central part of the end cap body 1 can be made of metal (such as aluminum alloy), while the outer periphery of the end cap body can be made of plastic. Preferably, the plastic for the outer periphery is the antibacterial plastic described in Embodiment 1.

[0096] Specifically, taking the end cap body 1 in Embodiment 2 as an example: Figures 11 to 12 The diagram shows a double-layer motor end cap. The end cap body 1 includes a central portion 16 and an outer peripheral portion 17. The outer peripheral portion 17 is located outside the central portion 16. The central portion 16 has a first through hole through which the motor shaft passes. The central portion 16 is made of metal, and the outer peripheral portion 17 is made of plastic. Making the central portion 16 of metal improves the accuracy and concentricity of the motor shaft passing through it, as well as increasing its supporting strength. Furthermore, making the outer peripheral portion 17 of plastic better addresses the problems of bacterial growth and rusting after the end cap body 1 comes into contact with sewage, while also reducing costs. The outer peripheral portion 17 and the central portion 16 can be formed by secondary overmolding or fixed with bolts.
