Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food waste disposal, and particularly relates to a food waste disposer. BACKGROUND

[0002] With the improvement of living standards, electrical appliances have been popular in every family, especially food waste disposer, which is convenient to use and has been widely used in our life. The food waste disposer is usually installed below the water outlet of the kitchen sink and used for grinding food waste. Since the food waste disposer is installed below the water outlet of the kitchen sink, and water flows into the food waste disposer during the working process, the waterproof requirement of the food waste disposer is very high, otherwise it will greatly affect the service life of the food waste disposer.

[0003] At present, the driving motor, control circuit board and other electrical components of the food waste disposer are usually installed at the bottom of the food waste disposer, so it is particularly important to prevent water from flowing into and infiltrating the bottom area of the food waste disposer.

[0004] In the prior art, in order to solve the waterproof problem of the electrical components at the bottom of the food waste disposer, a steel cylinder is arranged in the lower half area of the food waste disposer, and the electrical components are arranged in the steel cylinder. By arranging the steel cylinder, the waterproof effect can be achieved, but the volume of the food waste disposer is increased and the cost is also increased. Since the food waste disposer is installed below the sink in the kitchen, and the space below the sink in the kitchen is usually narrow, it will cause inconvenience when installing the food waste disposer, or the volume of the food waste disposer will be too large to avoid, which will result in a smaller design space in the lower half of the food waste disposer. Thus, some function settings of the food waste disposer are limited, and the design difficulty of the lower half structure of the food waste disposer is also increased.

[0005] In addition, even if the waterproof problem is solved by arranging the steel cylinder, the electrical components in the lower half of the food waste disposer still have the risk of being damaged due to water leakage or infiltration. Since the sealing part connecting the feed inlet of the food waste disposer and the water outlet of the sink will be worn after a long time of work (vibration during work), there will be water infiltration or dripping on the top of the food waste disposer, and then the water will infiltrate along the surface of the food waste disposer body (the food waste disposer body is covered with an outer shell). Once the water infiltrates into the bottom of the food waste disposer along the outer surface of the food waste disposer, there will be a risk of motor burnout, circuit board short circuit or metal part rusting due to water infiltration. SUMMARY

[0006] The application aims to provide a food waste disposer which can improve the overall waterproof reliability of the product.

[0007] To achieve the above-mentioned purpose, the application adopts the following technical solutions.

[0008] A food waste disposer comprises a shell and a motor end cover, the upper end of the interior of the shell is provided with a grinding part, the lower end of the interior of the shell is provided with a containing space for installing electrical components, the motor end cover is located between the grinding part and the containing space, and further comprises:

[0009] A flow guide is arranged outside the side wall of the grinding part or outside the side wall of the motor end cover.

[0010] A water collecting tank is arranged inside the side wall of the shell, and the water collecting tank is located below the flow guide and is used to collect liquid from the flow guide.

[0011] A drainage structure is in communication with the water collecting tank and is used to drain the liquid in the water collecting tank to the outside of the shell.

[0012] Specifically, by arranging the flow guide and the water collecting tank which cooperate with each other, the liquid on the side wall of the grinding part or the motor end cover is longitudinally blocked and collected in the water collecting tank and finally drained to the outside of the shell, on the one hand, the liquid can be prevented from flowing downward to the containing space of the electrical components, thereby effectively protecting the motor and other electrical components, and the product reliability is improved; on the other hand, the waterproof steel cylinder structure can be cancelled, which can reduce the cost of the food waste disposer, reduce the size of the lower half of the food waste disposer, and further make the utilization space of the lower half of the food waste disposer larger and reduce the design difficulty; on the other hand, since the utilization space of the lower half of the food waste disposer is larger, more functional circuits with functions can be arranged in the containing space of the electrical components, and the food waste disposer has more functions.

[0013] Preferably, the flow guide is arranged outside the side wall of the grinding part or the motor end cover in a 360-degree manner.

[0014] Preferably, the drainage structure is connected with the bottom of the water collecting tank.

[0015] Specifically, although the connection between the grinding part and the motor end cover is provided with a sealing structure, there is still a risk of liquid leakage at the connection after a long period of use, by arranging the flow guide on the motor end cover, i.e. the flow guide is located below the connection, the liquid leaked from the connection can be drained and finally drained to the outside of the shell through the drainage structure, thereby effectively improving the waterproof reliability of the food waste disposer.

[0016] Specifically, by arranging the flow guide on the side wall of the relatively upper grinding part, the liquid can be prevented from flowing along the side wall of the grinding part, the outer surface of the grinding part is reduced in contact with the liquid, and the grinding part is prevented from being rusted or corroded to be structurally damaged after long time use, thereby effectively improving the service life of the product.

[0017] As a preferred technical solution, when the flow guide is arranged on the motor end cover, the cross section of the flow guide is in the shape of "one", and the end of the flow guide away from the motor end cover is overlapped above the water collecting tank, and the flow guide is used to guide the liquid outside the side wall of the motor end cover to the water collecting tank.

[0018] Preferably, the flow guide is arranged horizontally or is arranged obliquely downward along the direction from the center to the periphery. The obliquely downward flow guide can make the liquid automatically reach the end of the flow guide away from the motor end cover, thereby ensuring the liquid to enter the water collecting tank.

[0019] As a preferred technical solution, a sealing member is arranged between the bottom of the end of the flow guide away from the motor end cover and the top of the side wall of the water collecting tank close to the motor end cover, and the sealing member is used to block the liquid from penetrating into the accommodating space along the bottom of the flow guide.

[0020] Specifically, by arranging the sealing member, it can be ensured that after the liquid flows along the upper surface of the flow guide to the end of the flow guide away from the motor end cover, the liquid cannot flow reversely along the lower surface of the flow guide to the end of the flow guide close to the motor end cover, thereby ensuring that the liquid no longer continues to flow downward along the side wall of the motor end cover, and improving the waterproof reliability of the product.

[0021] As a preferred technical solution, the cross section of the flow guide is in the shape of "L", the end of the flow guide away from the motor end cover is bent upward, and the bottom of the flow guide is provided with a liquid passing structure, and the liquid passing structure is used to discharge the liquid of the flow guide to the water collecting tank.

[0022] Specifically, by arranging the upwardly bent flow guide, the flow guide forms a water storage structure, realizes the collection of the liquid, and then transfers the liquid to the water collecting tank through the liquid passing structure and finally discharges the liquid to the outside of the shell. This design realizes the collection of the liquid on the motor end cover itself, shortens the flow distance of the liquid, and can improve the reliability of the liquid collection process and the discharge process.

[0023] Preferably, the upwardly bent flow guide with the suspended end is arranged on the motor end cover.

[0024] Preferably, the flow guide comprises an extension and a bent portion, further, the liquid passing structure hole is a transverse hole penetrating through the bent portion, and the height of the lower edge of the transverse hole is lower than or equal to the height of the upper surface of the extension; or the liquid passing structure is a longitudinal hole penetrating through the extension; or the liquid passing structure is a liquid passing pipe in communication with the bottom of the flow guide.

[0025] As a preferred technical solution, the water collecting groove is an arc-shaped groove arranged partially around the inner side of the side wall of the shell, or a ring-shaped groove arranged 360 degrees around the inner side of the side wall of the shell.

[0026] Specifically, the arc-shaped groove design can shorten the length of the water collecting groove, thereby making the structure of the water collecting groove simpler, reducing the material cost of the shell and reducing the occupied space of the water collecting groove.

[0027] Further, the arc-shaped groove is located directly below the liquid passing structure.

[0028] Preferably, when the number of liquid passing structures is one, the water collecting groove is an arc-shaped groove or a 360-degree ring-shaped groove located below the liquid passing structure; when the number of liquid passing structures is more than one, the water collecting groove is a plurality of arc-shaped grooves or a 360-degree ring-shaped groove located below the liquid passing structures, further, the number of water collecting grooves is equal to or less than the number of liquid passing structures, that is, a plurality of liquid passing structures can correspond to one water collecting groove.

[0029] As a preferred technical solution, the cross section of the flow guide is "L" shaped, one end of the flow guide away from the grinding portion or the motor end cover is bent downward, and the one end of the flow guide away from the grinding portion or the motor end cover is inserted into the water collecting groove, the flow guide being used to guide the liquid outside the side wall of the grinding portion or the motor end cover to the water collecting groove.

[0030] Preferably, the flow guide comprises an extension and a bent portion, further, when the flow guide is arranged on the motor end cover, the extension is overlapped on the water collecting groove, and the bent portion is inserted into the water collecting groove. When the flow guide is arranged on the grinding portion, the bent portion is inserted into the water collecting groove.

[0031] Preferably, the extension and the bent portion are integrally formed or detachably connected.

[0032] Specifically, by setting the downwardly bent "L"-shaped flow guide, it can be ensured that the liquid flowing along the upper surface of the flow guide cannot flow reversely along the lower surface of the flow guide to the end of the flow guide close to the grinding part or the motor end cover and reliably enter the water collecting groove, thereby ensuring that the liquid no longer continues to flow downward along the side wall of the grinding part or the motor end cover, and improving the waterproof reliability of the product.

[0033] As a preferred technical solution, the side wall of the motor end cover is provided with a sewage outlet, and when the flow guide is arranged on the motor end cover, the flow guide is located below the sewage outlet.

[0034] Specifically, the sewage outlet is used to connect with an external sewage pipeline to realize the external discharge of food waste. When used for a long time, there is a risk of water leakage at the connection between the sewage outlet and the sewage pipeline. By arranging the sewage outlet above the flow guide, the liquid leaked at the connection can be drained and finally discharged to the outside of the shell through the drainage structure, thereby effectively improving the waterproof reliability of the food waste disposer.

[0035] As a preferred technical solution, the water collecting groove is arranged on the inner side of the side wall of the shell in a 360-degree surrounding manner.

[0036] Specifically, by arranging the 360-degree surrounding water collecting groove, all the liquid on the flow guide can be more reliably collected, thereby improving the waterproof reliability.

[0037] As a preferred technical solution, the shell is cylindrical, and the shell includes an upper shell part and a lower shell part. The diameter of the upper shell part is greater than that of the lower shell part. The connection between the upper shell part and the lower shell part forms a stepped structure. The water collecting groove is arranged at the connection between the upper shell part and the lower shell part.

[0038] Specifically, on the one hand, the stepped structure at the connection is used to arrange the water collecting groove, which can simplify the structure and production process of the shell, thereby reducing the cost of the shell. On the other hand, the shape of the shell is set as large at the top and small at the bottom, which is more beautiful in appearance and is also more conducive to the installation and transportation of the food waste disposer.

[0039] As a preferred technical solution, the drainage structure is a drainage opening formed in the bottom of the water collecting groove. One end of the drainage opening communicates with the water collecting groove, and the other end of the drainage opening is located outside the side wall of the shell.

[0040] Alternatively, the drainage structure is a drainage channel extending longitudinally along the side wall of the shell. One end of the drainage channel communicates with the water collecting groove, and the other end of the drainage channel is located at the bottom of the shell.

[0041] Preferably, the bottom of each of the water collecting groove is provided with at least one drainage structure.

[0042] Preferably, the drainage channel is located on the outside or the inside of the side wall of the shell.

[0043] Specifically, the drainage structure is designed as a drainage port to directly discharge the liquid outside the shell, and the design structure and process are simple and high in production efficiency. The drainage structure is designed as a drainage channel, and the outlet of the liquid is located below the accommodation space of the electrical device, which can ensure the isolation of the liquid and the electrical device, and the waterproof reliability of the product is higher.

[0044] The food waste disposer has the advantages that: the liquid on the sidewall of the grinding part or the motor end cover is longitudinally blocked and collected in the water collecting groove by the cooperation of the flow guide member and the water collecting groove, and is finally discharged outside the shell, which can avoid the liquid flowing down to the accommodation space of the electrical device, thereby effectively protecting the electrical device such as the motor, and improving the product reliability; on the other hand, the waterproof steel cylinder structure can be cancelled, which can reduce the cost of the food waste disposer, reduce the size of the lower half of the food waste disposer, thereby making the utilization space of the lower half of the food waste disposer larger, reducing the design difficulty; on the other hand, the utilization space of the lower half of the food waste disposer is larger, and more functional circuits can be arranged in the accommodation space of the electrical device, so that the food waste disposer has more functions.

[0070] The technical solutions of the present application will be further described below with reference to the drawings and through specific embodiments.

[0071] Embodiment one:

[0072] As shown in Figures 1 to 7 A food waste disposer, comprising a shell 1 and a motor end cover 23, the upper end of the inside of the shell 1 is provided with a grinding part 22, and the lower end of the inside of the shell 1 is provided with a containing space 3 for installing electrical components (the containing space 3 is specifically shown in Figure 3 and Figure 5), the motor end cover 23 is located between the grinding part 22 and the accommodating space 3, and also includes a guide member 21, a water collecting trough 11 and a drainage structure. The guide member 21 is arranged on the outside of the side wall of the motor end cover 23, and the water collecting trough 11 is arranged on the inside of the side wall of the shell 1. The water collecting trough 11 is located below the guide member 21. The water collecting trough 11 is used to collect liquid from the guide member 21. The drainage structure is connected to the water collecting trough 11 and is used to discharge the liquid in the water collecting trough 11 to the outside of the shell 1. Specifically, by providing a flow guide 21 and a water collecting trough 11 that cooperate with each other, the liquid on the side wall of the motor end cover 23 is longitudinally blocked and collected in the water collecting trough 11, and finally discharged to the outside of the shell 1. On the one hand, it can prevent the liquid from continuing to flow downward along the motor end cover 23 to the accommodating space 3 for electrical components, thereby effectively providing waterproof protection for electrical components such as the motor, thereby improving product reliability; on the other hand, the waterproof steel cylinder structure can be eliminated, which can reduce the cost of the food waste disposer and reduce the size of the lower half of the food waste disposer, thereby making the utilization space of the lower half of the food waste disposer larger and reducing the design difficulty; on the other hand, since the utilization space of the lower half of the food waste disposer is larger, more functional circuits can be set in the accommodating space 3 for electrical components, making the food waste disposer more functional.

[0073] In this embodiment, the guide member 21 is preferably arranged 360 degrees around the outside of the side wall of the motor end cover 23, and the drainage structure is connected to the bottom of the water collecting tank 11. Figure 4 、 Figure 5 and Figure 7 As shown, the housing 1 is cylindrical and includes an upper housing portion 14 and a lower housing portion 15. The diameter of the upper housing portion 14 is larger than that of the lower housing portion 15. The connection between the upper housing portion 14 and the lower housing portion 15 forms a stepped structure. The water collection tank 11 is provided at the connection between the upper housing portion 14 and the lower housing portion 15. Specifically, on the one hand, using the stepped structure of the connection to provide the water collection tank 11 can simplify the structure and production process of the housing 1, thereby reducing the cost of the housing 1. On the other hand, setting the shape of the housing 1 to be larger at the top and smaller at the bottom makes the appearance more beautiful. Moreover, since the shape is set to be larger at the top and smaller at the bottom, it is also easier to apply force at the stepped structure, which is also more conducive to the installation and transportation of the food waste disposer.

[0074] In this embodiment, if Figure 2 and Figure 3As shown, the motor end cover 23 is located below the grinding part 22, and the flow guide 21 is arranged outside the side wall of the motor end cover 23. Specifically, although a sealing structure is arranged at the connection between the grinding part 22 and the motor end cover 23, there is still a risk of liquid leakage at the connection after a long period of use. By arranging the flow guide 21 on the motor end cover 23, i.e. below the connection, the liquid leaked from the connection can be drained and finally discharged to the outside of the housing 1 through the drainage structure, thereby effectively improving the waterproof reliability of the food waste disposer.

[0075] Further, a drain opening 231 is arranged on the side wall of the motor end cover 23, and the drain opening 231 is located above the flow guide 21. The drain opening 231 is used to connect with the external drain pipeline 4 to realize the external discharge of food waste. After a long period of use, there is a risk of water leakage at the connection between the drain opening 231 and the drain pipeline 4. By arranging the drain opening 231 above the flow guide 21, the liquid leaked from the connection can be drained and finally discharged to the outside of the housing 1 through the drainage structure, thereby effectively improving the waterproof reliability of the food waste disposer.

[0076] In the embodiment, as shown in Figures 3 to 6 , the cross section of the flow guide 21 is "L" shaped, and the end of the flow guide 21 away from the motor end cover 23 is bent downward. The end of the flow guide 21 away from the motor end cover 23 is hung on the water collecting groove 11, and the flow guide 21 is used to drain the liquid outside the side wall of the motor end cover 23 to the water collecting groove 11. As a preferred solution, the flow guide 21 includes an extension part 211 and a bent part 212, the extension part 211 is lapped on the water collecting groove 11, and the bent part 212 is inserted into the water collecting groove 11. By arranging the "L" shaped flow guide 21 bent downward, it can be ensured that the liquid flowing along the upper surface of the flow guide 21 cannot flow reversely along the lower surface of the flow guide 21 to the end of the flow guide 21 close to the motor end cover 23 after flowing to the end of the flow guide 21 away from the motor end cover 23, thereby ensuring that the liquid does not continue to flow downward along the side wall of the motor end cover 23, and improving the waterproof reliability of the product.

[0077] In addition, the extension part 211 and the bent part 212 in the embodiment are integrally formed. Of course, in other embodiments, as shown in Figure 8 and Figure 9 , the extension part 211 and the bent part 212 can also be detachably connected, thereby improving the versatility of the product and the flexibility of the product assembly process.

[0078] In the embodiment, the water collecting groove 11 is arranged on the inner side of the side wall of the housing 1 in 360 degrees. By arranging the 360 degree surrounding water collecting groove 11, all the liquid on the flow guide 21 can be more reliably collected, thereby improving the waterproof reliability.

[0079] In the embodiment, as shown inFigure 4 and Figure 6 As shown, the drainage structure is a drain port 12 provided at the bottom of the sump 11. One end of the drain port 12 is connected to the sump 11, and the other end of the drain port 12 is located outside the side wall of the housing 1. Each sump 11 is provided with at least one drainage structure at the bottom. Designing the drainage structure as a drain port 12 allows liquid to be discharged directly to the exterior of the housing 1. This design and process are simple and highly efficient.

[0080] Example 2:

[0081] The difference between this embodiment and the first embodiment is that the structure of the flow guide 21 is different. In this embodiment, Figure 10 and Figure 11 As shown, the cross-section of the flow guide 21 is I-shaped. The end of the flow guide 21 away from the motor end cover 23 overlaps the water collection tank 11. The flow guide 21 is used to guide liquid outside the side wall of the motor end cover 23 to the water collection tank 11. In this embodiment, a seal 5 is provided between the bottom of the end of the flow guide 21 away from the motor end cover 23 and the top of the side wall of the water collection tank 11 near the motor end cover 23. The seal 5 is used to prevent liquid from penetrating along the bottom of the flow guide 21 and entering the accommodating space 3. Specifically, the provision of the seal 5 ensures that after the liquid flows along the upper surface of the flow guide 21 to the end of the flow guide 21 away from the motor end cover 23, it cannot flow back along the lower surface of the flow guide 21 to the end of the flow guide 21 near the motor end cover 23. This ensures that the liquid no longer continues to flow downward along the side wall of the motor end cover 23, thereby improving the waterproof reliability of the product.

[0082] Furthermore, the guide member 21 is arranged horizontally, or the guide member 21 is arranged downwardly in a direction from the center to the periphery, preferably a downwardly inclined design. The downwardly inclined guide member 21 can automatically allow the liquid to reach the end of the guide member 21 away from the motor end cover 23, thereby ensuring that the liquid enters the water collection tank 11.

[0083] Example 3:

[0084] The difference between this embodiment and the first embodiment lies in the different structural designs of the flow guide 21 and the water collecting tank 11. In this embodiment, Figures 12 to 15As shown, the cross section of the flow guide 21 is "L" shaped, the end of the flow guide 21 away from the motor end cover 23 is bent upwards, and the bottom of the flow guide 21 is provided with a liquid passing structure 213 for discharging the liquid on the flow guide 21 to the water collecting groove 11. By providing the upwardly bent flow guide 21, the flow guide 21 forms a water storage structure, which collects the liquid, and then transfers the liquid to the water collecting groove 11 through the liquid passing structure 213, and finally discharges the liquid to the outside of the shell 1. This design realizes the collection of the liquid on the motor end cover 23 itself, shortens the flow distance of the liquid, and improves the reliability of the liquid collection and discharge processes. In this embodiment, as shown, the liquid passing structure 213 is a transverse hole penetrating the bent portion 212, and the height of the lower edge of the transverse hole is lower than or equal to the height of the upper surface of the extension portion 211. In addition, the liquid passing structure 213 in the Figure 15 as shown, the liquid passing structure 213 is a transverse hole penetrating the bent portion 212, and the height of the lower edge of the transverse hole is lower than or equal to the height of the upper surface of the extension portion 211. In addition, the liquid passing structure 213 in the Figure 15 the liquid passing structure 213 is a transverse hole, which is arranged directly below the pollution discharge port 231. In actual applications, the number of the transverse holes can be multiple, and the positions thereof can be arranged as needed. In other embodiments, the liquid passing structure 213 can also be a longitudinal hole (not shown in the figure) penetrating the extension portion 211, and the number and position of the longitudinal hole can be arranged as needed; or the liquid passing structure 213 is a liquid passing pipe (not shown in the figure), one end of which is open and communicates with the flow guide 21 (preferably the bottom of the flow guide), and the other end of which is open and communicates with the water collecting groove 11, for guiding the liquid on the flow guide 21 to the water collecting groove 11, that is, the liquid passing pipe at this time is equivalent to a flow guide pipe for communicating the flow guide 21 and the water collecting groove 11. In actual product applications, the liquid passing structure is preferably in the form of the above-mentioned liquid passing pipe.

[0085] In addition, in this embodiment, the water collecting groove 11 is an arc-shaped groove arranged partially around the inner side of the side wall of the shell 1. Of course, in other embodiments, the water collecting groove 11 can also be a ring-shaped groove arranged 360 degrees around the inner side of the side wall of the shell 1. Specifically, in this embodiment, the arc-shaped groove design can shorten the length of the water collecting groove 11, and further simplify the structure of the water collecting groove 11, thereby reducing the material cost of the shell 1 and reducing the occupied space of the water collecting groove 11. In this embodiment, the number of the liquid passing structures 213 is one, and the water collecting groove 11 is an arc-shaped groove located directly below the liquid passing structure 213. Of course, in other embodiments, the water collecting groove 11 can also be designed as a 360-degree ring-shaped groove. In addition, in other embodiments, when the number of the liquid passing structures 213 is more than two, the water collecting groove 11 is a plurality of arc-shaped grooves or a 360-degree ring-shaped groove located below the liquid passing structures 213. Further, the number of the water collecting grooves 11 is equal to or less than the number of the liquid passing structures 213, that is, one water collecting groove 11 can correspond to a plurality of liquid passing structures 213.

[0086] Embodiment Four:

[0087] The difference between this embodiment and embodiment one is the setting position of the flow guide 21. In this embodiment, as shown in Figure 16 and Figure 17 , the shell 1 is provided with a grinding part 22 and a motor end cover 23, the motor end cover 23 is located below the grinding part 22, and the flow guide 21 is arranged outside the side wall of the grinding part 22. By arranging the flow guide 21 on the side wall of the relatively upper grinding part 22, the liquid can be prevented from continuing to flow along the side wall of the grinding part 22, the outer surface of the grinding part 22 is reduced to contact with the liquid, and the grinding part 22 is prevented from being rusted or corroded to damage the structure after being used for a long time, thereby effectively improving the service life of the product.

[0088] The cross section of the flow guide 21 is "L" shape, the end of the flow guide 21 away from the grinding part 22 is bent downward, the end of the flow guide 21 away from the grinding part 22 is inserted into the water collecting groove 11, and the flow guide 21 is used to guide the liquid outside the side wall of the grinding part 22 to the water collecting groove 11. Specifically, by arranging the "L" shaped flow guide 21 bent downward, and the end of the flow guide 21 is inserted into the water collecting groove 11, it can be ensured that the liquid flowing along the upper surface of the flow guide 21 cannot flow reversely along the lower surface of the flow guide 21 to the end of the flow guide 21 close to the grinding part 22 and reliably enter the water collecting groove 11, thereby ensuring that the liquid no longer continues to flow downward along the side wall of the grinding part 22, and improving the waterproof reliability of the product.

[0089] Embodiment five:

[0090] The difference between this embodiment and embodiment one is the drainage structure. In this embodiment, as shown in Figure 18 and Figure 19 , the drainage structure is a drainage channel 13 extending longitudinally along the side wall of the shell 1, one end of the drainage channel 13 communicates with the water collecting groove 11, and the other end of the drainage channel 13 is located at the bottom of the shell 1. Further, the drainage channel 13 can be located outside or inside the side wall of the shell 1. By designing the drainage structure as the drainage channel 13, the outlet of the liquid is located below the accommodation space 3 of the electrical component, which can ensure the isolation of the liquid and the electrical component, and the waterproof reliability of the product is higher.

[0091] Embodiment six:

[0092] A food waste disposer includes a shell and a motor end cover, an upper end of an inside of the shell is provided with a grinding part, a lower end of the inside of the shell is provided with an accommodation space for mounting an electrical component (the accommodation space can refer to the mark 3 of Figure 3 and Figure 5 ), the motor end cover is located between the grinding part and the accommodation space, and a flow guide is further included, the flow guide is arranged outside the side wall of the motor end cover.

[0093] The cross section of the flow guide is "L" shape, and the end of the flow guide away from the motor end cover is bent upwards. Specifically, as shown in Figure 13 and Figure 14 the flow guide 21 includes an extension part 211, a bent part 212 and a liquid passing pipe (not shown in the figure), the bent part 212 is bent upwards relative to the extension part 211, and the liquid passing pipe is connected with the extension part 211 or the bent part 212, and is used to discharge the liquid of the flow guide to the outside of the housing. Specifically, a water drainage accommodation hole (not shown in the figure) is formed on the housing, one end of the liquid passing pipe is connected with the flow guide (preferably the extension part of the flow guide), and the other end of the liquid passing pipe penetrates through the water drainage accommodation hole of the housing and extends to the outside of the housing. By setting the flow guide bent upwards, the flow guide forms a water storage structure, so as to collect the liquid, and then directly transfer the liquid to the outside of the housing through the liquid passing structure. This design realizes the collection and direct drainage of the liquid on the motor end cover itself, which can omit the water collecting groove structure on the housing, shorten the flow distance of the liquid, and improve the reliability of the liquid collection and drainage processes.

[0094] As a preferred embodiment, the flow guide is arranged in a 360 degree ring on the outer side of the side wall of the motor end cover. As shown in Figure 14 the bent part 212 is closely connected with the side wall of the housing, so as to prevent the liquid collected by the flow guide from seeping downwards into the accommodating space. In order to further improve the waterproof effect, a sealing part (not shown in the figure) is arranged between the bent part and the side wall of the housing, and the sealing part can be a sealing ring, a sealing gasket, etc.

[0095] Of course, in other embodiments, the flow guide can also be arranged on the side wall of the grinding part, and other structures are the same as those of the above-mentioned embodiment six.

[0096] It should be noted that the flow guide structure, the water collecting groove structure and the water drainage structure in each embodiment can be applied to other embodiments as needed, for example, the flow guide structure, the liquid passing structure and the water collecting groove structure of the motor end cover in embodiment three can also be applied to embodiment four, that is, the flow guide structure of the motor end cover in embodiment three is transplanted and applied to the grinding part, and the liquid passing structure and the water collecting groove structure of embodiment three are applied to embodiment four; for example, the water drainage structure in embodiment five can also be applied to embodiments two to four, and the like, which will not be described one by one here.

[0097] In addition, the above merely is the preferred embodiment of the present application and the applied technical principles, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present application. Therefore, although the present application is described in more detail through the above embodiments, the present application is not limited to the above embodiments only, and more other equivalent embodiments can be included without departing from the concept of the present application, and the scope of the present application is determined by the appended claims.
