Description

Technical Field

[0001] This disclosure relates to the field of cleaning device technology, and more particularly to an automatic cleaning device for water tanks. Background Technology

[0002] After completing its underwater cleaning task, the automatic pool cleaning device requires the user to lift it out of the water to shore for further cleaning or charging. During this process, because the device is filled with water, the user has to lift it, as the weight includes the device's own weight plus the weight of the remaining water, making it strenuous and resulting in a poor user experience. Furthermore, because the residual water drains slowly, even after the device is lifted to shore and laid flat, the remaining water continues to slowly drain, causing continuous water seepage around the device and further impacting the user experience.

[0003] To address this issue, existing automatic sink cleaning devices typically have drainage holes and water-retaining rubber strips at the bottom or rear of the machine. When the device is lifted, residual water flows out through the rubber strips and drainage holes, enabling rapid drainage of water inside the machine. However, besides the water inside the machine, a significant amount of water also remains inside the trash basket and in the outer cavity (i.e., the trash basket compartment). This water cannot be directly drained through the aforementioned drainage rubber strips to ensure the airtightness of the flow channel. Alternatively, a separate drainage hole and corresponding drainage rubber strip must be installed on the trash basket compartment. When drainage is needed, the water in the trash basket compartment must first be drained into the casing and then discharged from the drain outlet on the casing. This complex drainage structure occupies structural space and may affect the drainage speed. Therefore, providing an automatic sink cleaning device with a simple structure, small footprint, and the ability to quickly drain water from inside the device, especially from the trash basket and its compartment, is urgently needed. Utility Model Content

[0004] The technical problem to be solved by this application is to address the shortcomings of the prior art by providing an automatic water tank cleaning device. By setting a first drain outlet on the housing and a second drain outlet in the garbage basket containing compartment in an area opposite to at least a part of the first drain outlet, water inside the garbage basket and the machine body can be discharged from the first and second drain outlets, thereby realizing the rapid discharge of water inside the automatic water tank cleaning device. The device has a simple structure and occupies little space.

[0005] In one aspect of this application, an automatic water tank cleaning device is provided, comprising: A housing, wherein a first drain outlet is provided on the housing; A garbage basket for filtering water that enters the garbage basket; and A garbage basket receiving compartment is disposed within the housing, and the garbage basket is detachably installed into the garbage basket receiving compartment. A second drain outlet is provided on the garbage basket receiving compartment in an area opposite at least a portion of the first drain outlet. A one-way valve is provided at the first drain outlet. When the one-way valve is closed, it can prevent water from flowing into the garbage basket from the first drain outlet and the second drain outlet. When the one-way valve is open, the water in the garbage basket can be discharged from the second drain outlet and the first drain outlet.

[0006] Furthermore, the one-way valve is located on the side of the housing away from the second drain port.

[0007] Furthermore, the first drain outlet is located at the bottom or side of the housing, and the second drain outlet is located at the bottom or side of the garbage basket receiving compartment.

[0008] Furthermore, the first drain outlet is located on the side of the housing near the bottom, and the second drain outlet is located on the side of the garbage basket container near the bottom of the housing.

[0009] Furthermore, the automatic cleaning device for the water tank also includes a water pump for driving water flow into the trash basket. When the water pump is in operation, the suction action of the water pump adsorbs the one-way valve onto the first drain outlet, so that the one-way valve is in a closed state. After the water pump stops working and the automatic cleaning device for the water tank is lifted out of the water, the one-way valve is in an open state under its own gravity and / or the gravity of the water flow.

[0010] Furthermore, a water flow separator is provided between the shell and the garbage basket receiving compartment, the water flow separator being used to prevent water flow between the shell and the garbage basket receiving compartment from entering the garbage basket from the second drain outlet.

[0011] Furthermore, the water flow separator is disposed around the second drain outlet.

[0012] Furthermore, there is a first space between the garbage basket holding compartment and the shell, and the water flow separator divides the first drain outlet into a first part and a second part, wherein the first part is connected to the first space, and the second drain outlet is connected to the second part.

[0013] Furthermore, the one-way valve is made of an elastic material.

[0014] Furthermore, the number of the first drain outlet and the second drain outlet is one or more, and each of the first drain outlet and the second drain outlet includes one or more drain holes.

[0015] The embodiments described in this application have the following beneficial effects: The automatic water tank cleaning device provided in this application has a first drain outlet inside the housing and a second drain outlet in the garbage basket containing the garbage bin, which is located in an area opposite to at least a portion of the first drain outlet. A one-way valve is installed at the first drain outlet. The opening and closing of the first drain outlet on the housing and the second drain outlet on the garbage basket containing the garbage bin can be controlled by the one-way valve. This realizes the sharing of drainage structures between the housing and the garbage basket containing the garbage bin, saving space occupied by drainage structures and reducing the number of drainage structures. Furthermore, when the machine is lifted out of the water, the one-way valve opens, and the water in the garbage basket containing the garbage bin can flow directly out from the second drain outlet and the first drain outlet, realizing rapid drainage of the garbage basket containing the garbage bin without affecting the sealing of the filter channel.

Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0020] This application provides an automatic pool cleaning device. This automatic pool cleaning device is capable of cleaning pools. The pool is, for example, a pool-shaped structure. The pool-shaped structure can be a swimming pool, a water storage tank, a spa pool, a water tank, a water storage trough, etc. The automatic pool cleaning device can be a device such as an automatic cleaning device or a pool cleaning robot, capable of cleaning the pool-shaped structure. This application does not limit the specific presentation of the automatic pool cleaning device or the pool-shaped structure, as long as the principle of this application is achieved. In the following description, unless otherwise specified, a pool cleaning robot will be used as an example of the automatic pool cleaning device, and a swimming pool will be used as an example of a pool or pool-shaped structure. In the following description, unless otherwise specified, the terms "pool surface," "pool water surface," and "pool surface" all refer to the water surface of a swimming pool.

Figure 1A This is a cross-sectional view showing an embodiment of an automatic water tank cleaning device according to this application. Figure 1A The example illustrates the positional relationship of the first drain outlet, the second drain outlet, the garbage basket, and the garbage basket holding compartment in an automatic water tank cleaning device.

Figure 5 This is a structural diagram showing the chassis of an automatic water tank cleaning device according to an embodiment of this application from another perspective. Figure 6 This is a structural diagram showing an embodiment of an automatic water tank cleaning device according to this application.

[0022] like Figure 1A and Figure 2As shown, this application provides an automatic water tank cleaning device, including: a housing 1, on which a first drain outlet 2 is provided; a garbage basket 3 for filtering water entering the garbage basket 3; and a garbage basket receiving compartment 4, disposed inside the housing 1, wherein the garbage basket 3 is detachably installed into the garbage basket receiving compartment 4, and a second drain outlet 5 is provided on the garbage basket receiving compartment 4 in an area opposite to at least a portion of the first drain outlet 2. A one-way valve 6 is provided at the first drain outlet 2. When the one-way valve 6 is in a closed state, it can prevent water from entering the garbage basket 3 from the first drain outlet 2 and the second drain outlet 5. When the one-way valve 6 is in an open state, water in the garbage basket 3 can be discharged from the second drain outlet 5 and the first drain outlet 2.

[0023] Specifically, the automatic water tank cleaning device includes components such as a housing 1, a first drain outlet 2, a garbage basket 3, a garbage basket holding compartment 4, and a water pump. The housing 1 is the main part of the automatic water tank cleaning device, used to provide physical protection for the other components of the automatic water tank cleaning device, as well as support points for installation and fixation, so that the components inside the automatic water tank cleaning device can maintain a stable structural relationship during operation and avoid damage from external impacts and water erosion.

[0024] The housing 1 is provided with a first drain outlet 2, which provides a channel for water inside the automatic water cleaning device to be discharged to the outside of the device. A trash basket 3 is disposed inside the housing 1, and a trash basket receiving compartment 4 is disposed inside the housing 1. The trash basket 3 is detachably installed inside the trash basket receiving compartment 4. The trash basket 3 is used to filter the water entering it, and the trash basket receiving compartment 4 provides storage space, a mounting base, and a flow channel for the trash basket 3.

[0025] The automatic cleaning device for the water tank also includes a water pump for driving water flow into the garbage basket 3. When the water pump is in operation, the suction action of the water pump will attract the one-way valve 6 to the first drain outlet 2, so that the one-way valve 6 is in the closed state. After the water pump stops working and the automatic cleaning device for the water tank is lifted out of the water, the one-way valve 6 is in the open state under its own gravity and / or the gravity of the water flow.

[0026] During the cleaning of the water tank by the automatic water tank cleaning device, the water pump is in operation. Water in the water tank is drawn into the automatic water tank cleaning device and flows towards the garbage basket receiving compartment 4. After passing through the guiding structure (such as a backflow ramp or guiding channel) within the garbage basket receiving compartment 4, the water enters the garbage basket 3, preventing water flow dispersion and escape, and providing a relatively sealed environment for the filter channel of the garbage basket 3. After the water enters the garbage basket 3, garbage in the water, such as leaves, branches, and paper scraps, is trapped in the garbage basket 3. The filtered water continues to be discharged from the drain outlet of the automatic water tank cleaning device under the action of the water pump.

[0027] like Figure 1A as well as Figure 2 As shown, a second drain 5 is provided on the garbage basket 4 in an area opposite to at least a portion of the first drain 2. A one-way valve 6 is provided at the first drain 2. When the one-way valve 6 is closed, it can prevent water from flowing into the garbage basket 3 from the first drain 2 and the second drain 5. When the one-way valve is open, the water in the garbage basket 3 can be discharged from the second drain 5 and the first drain 2.

[0028] For example, such as Figure 1A and Figure 2 As shown, a first drain outlet 2 is provided on the rear side wall of the housing 1, and a second drain outlet 5 is provided on the garbage basket 4 (e.g., on the rear side wall of the garbage basket 4). A portion of the area opposite to the second drain outlet 2 overlaps with that of the first drain outlet 2, and the corresponding areas of the second drain outlet 5 and the first drain outlet 2 are abutting or adjacent to each other, forming a simple and compact overall structure. The portion of the first drain outlet 2 that does not overlap with the second drain outlet 5 faces the space inside the housing 1 (e.g., the space between the inner wall of the housing 1 and the outer wall of the garbage basket 4). A one-way valve 6 is provided at the first drain outlet 2, which can cover both the first drain outlet 2 and the second drain outlet 5. It should be noted that the above description of the locations of the first drain outlet 2 and the second drain outlet 5 is merely exemplary; they can be placed in other reasonable locations (e.g., the first drain outlet 2 can be placed on the bottom surface of the housing 1, and correspondingly, the second drain outlet 5 can be placed on the bottom surface of the garbage basket 4), as long as the technical principles of this application are achieved, they are within the scope of protection of this application.

[0029] During the cleaning process of the automatic water tank cleaning device, the water pump is in operation. Due to the pump's suction, a negative pressure is created inside the device, causing the one-way valve 6 to adhere to the first drain outlet 2. Simultaneously, because the second drain outlet 5 is directly opposite the first drain outlet 2 and the gap between them is small, when the one-way valve 6 adheres to the first drain outlet 2, it can simultaneously close both outlets. Alternatively, the structure of the one-way valve 6 can be designed based on the structures of the first and second drain outlets 2 and 5. For example, protrusions can be added to the valve 6 so that when it adheres to the first drain outlet 2, the protrusions can block the second drain outlet 5, thus better closing both outlets.

[0030] In one example, the one-way valve 6 is made of a resilient material.

[0031] For example, the one-way valve 6 is made of an elastic material. When subjected to force, the elastic material deforms, thus opening or closing the one-way valve 6. For example, the one-way valve 6 is made of drainage soft rubber. The drainage soft rubber can deform outward relative to the machine body under the action of external force, thereby opening the first drain port 2. However, the drainage soft rubber is blocked by the first drain port 2 and cannot deform into the automatic cleaning device of the pool. Instead, it can only stick tightly to the first drain port 2, thereby closing the first drain port 2. When the water pump in the automatic water cleaning device is turned on, the suction of the water pump causes the drain rubber to adhere tightly to the housing 1, preventing water from outside the automatic water cleaning device from entering the device through the first drain outlet 2. When the automatic water cleaning device completes its cleaning task and is lifted out of the water, the water pump is turned off. At this time, the water inside the device exerts an outward force on the drain rubber under the action of gravity. The drain rubber deforms outward under its own weight and / or the gravity of the water flow, and the one-way valve 6 is in the open state. The water inside the automatic water cleaning device and the water inside the trash basket 3 are discharged from the first drain outlet 2 and the second drain outlet 5 to the outside of the device, achieving the purpose of rapid drainage.

[0032] It should be noted that this application does not limit the specific material of the one-way valve 6. The drainage soft rubber is only an illustrative example of this application. Those skilled in the art can make settings according to actual use needs, as long as the technical principle of this application can be realized.

[0033] like Figure 2 , Figure 5 and Figure 6As shown, the one-way valve 6 completely covers the first drain outlet 2 and the second drain outlet 5. Due to the blocking and sealing effect of the one-way valve 6, the water in the pool will not enter the automatic pool cleaning device through the first drain outlet 2, nor will it enter the garbage basket holding compartment 4 and garbage basket 3 through the second drain outlet 5. Thus, it can be ensured that the suction force of the water pump acts as much as possible on the bottom suction port of the automatic pool cleaning device, thereby ensuring the cleaning effect of the automatic pool cleaning device through the bottom suction port. After the automatic water tank cleaning device completes its cleaning task, the water pump stops working. When the automatic water tank cleaning device is lifted out of the water, the first drain outlet 2 and the second drain outlet 5 are generally located near the tail of the machine. When the user lifts the handle of the machine head, the tail is facing down, and the water remaining inside the automatic water tank cleaning device flows down to the tail under the action of gravity, that is, it can flow towards the location of the first drain outlet 2 and the second drain outlet 5. The one-way valve 6 is in the open state under its own weight and / or the gravity of the water flow. At this time, the water inside the machine body can be discharged from the first drain outlet 2, and the water in the garbage basket 3 and the garbage basket holding compartment 4 can be discharged from the second drain outlet 5 and the first drain outlet 2. That is, the water in the garbage basket 3 and the garbage basket holding compartment 4 can be directly discharged to the outside of the automatic water tank cleaning device (instead of first being discharged into the internal space of the machine body and then discharged to the outside of the automatic water tank cleaning device), realizing the rapid discharge of the water in the garbage basket 3 and the garbage basket holding compartment 4.

[0034] In this way, by setting a first drain outlet 2 on the shell 1 and a second drain outlet 5 on the garbage basket 4 in an area opposite at least a portion of the first drain outlet 2, and by setting the drainage structure of the garbage basket 4 in contact with or adjacent to the drainage structure of the machine body, residual water inside the machine body and residual water in the garbage basket 3 can be quickly discharged to the outside of the automatic cleaning device of the pool. This avoids the problem of water continuously and slowly seeping out of the machine after the machine is lifted out, causing the bank to become slippery. The overall structure is simple, and while occupying little internal space and reducing the number of parts, it achieves the effects of fast drainage speed and good flow channel sealing. At the same time, a one-way valve 6 is set on the first drain outlet 2, which can be used by both the first drain outlet 2 and the second drain outlet 5, further simplifying the structure and reducing the number of parts.

[0035] The number of the first drain outlet 2 and the second drain outlet 5 is one or more, and each of the first drain outlet 2 and the second drain outlet 5 includes one or more drain holes.

[0036] The number of the first drain outlet 2 and the second drain outlet 5 can be one or more. For example, Figure 3 and Figure 4 As shown, two first drain outlets 2 (one on the left and one on the right) are provided on the housing 1, and correspondingly, two second drain outlets 5 (one on the left and one on the right) are provided.

[0037] Each first drain outlet 2 may include one drain hole or multiple drain holes; each second drain outlet 5 may include one drain hole or multiple drain holes. Figure 3 , Figure 4 As shown, both the first drain outlet 2 and the second drain outlet 5 can include multiple drain holes, such as grid-like drain holes. This divides the area of ​​the drain outlet into multiple small pieces. When the water pump is drawing water, an excessively large drain outlet may cause uneven suction at different points, resulting in insufficient suction at some drain outlets. Consequently, the one-way valve 6 cannot tightly adhere to the drain outlet, failing to properly close the first drain outlet 2 and the second drain outlet 5, thus affecting the sealing effect of the machine's filter channel. The number of the first drain outlet 2, the second drain outlet 5, and the drain holes is determined based on the internal space of the automatic water tank cleaning device and the usage requirements, and this application does not impose any limitations on this.

[0038] It should be noted that this application does not limit the shape and structure of the first drain outlet 2 and the second drain outlet 5. The first drain outlet 2 and the second drain outlet 5 can be circular, square, or conical circular. The drain holes in the first drain outlet 2 and the second drain outlet 5 can be circular holes, elongated holes, or grid holes. Those skilled in the art can make the settings according to actual use needs, as long as they meet the technical principles of this application.

[0039] It should be understood that this application does not limit the installation method of the garbage basket 3 within the garbage basket holding compartment 4, and any installation method that realizes the technical concept of this application is within the protection scope of this application. For example, the detachable installation method can be a snap-fit ​​connection, that is, detachment is achieved through the cooperation of elastic snaps and slots, including press-type snaps, rotation-type snaps, etc.; the detachable installation method can also be a pull-out connection, that is, detachment is achieved through the cooperation of a drawer and a guide rail groove; the detachable installation method can also be a threaded connection, that is, detachment is achieved through the helical cooperation of internal and external threads, or it can be a magnetic connection, or a quick-release locking connection, or even a combination of the above-mentioned detachable connection methods. Those skilled in the art can set it according to actual use needs, as long as it meets the technical principles of this application.

[0040] It should be noted that the automatic pool cleaning device may also include components such as handles, water inlets, sensors, and controllers disposed on or inside the housing. Those skilled in the art can select and configure the constituent components (e.g., components disposed on or inside the housing) of the automatic pool cleaning device according to the principles of this application, as long as the technical principles of this application can be realized.

[0041] In one example, the one-way valve 6 is located on the side of the housing 1 away from the second drain port 5.

[0042] For example, such as Figure 1A and Figure 2 as well as Figures 4-6 As shown, the one-way valve 6 is located on the outer wall of the housing 1, away from the second drain outlet 5. Therefore, the one-way valve 6 can open outward relative to the machine body, but cannot open into the automatic water tank cleaning device, forming a one-way opening structure. Thus, when the one-way valve 6 is closed, it is pressed against the first drain outlet 2, simultaneously closing both the first and second drain outlets 5. Water in the pool will not enter the machine body through the first drain outlet 2, nor will it enter the garbage basket 4 through the second drain outlet 5. When the one-way valve 6 is open, it opens outward to the automatic water tank cleaning device, allowing water inside the machine body (including water inside the garbage basket 3 and the garbage basket 4) to be discharged through the first drain outlet 2 and the second drain outlet 5.

[0043] In one example, the first drain outlet 2 is located at the bottom or side of the housing 1, and the second drain outlet 5 is located at the bottom or side of the garbage basket receiving compartment 4.

[0044] For example, such as Figures 1A-6 As shown, the first drain outlet 2 is located at the bottom of the housing 1, or at the side of the housing 1. Correspondingly, the second drain outlet 5 is located at the bottom of the garbage basket 4, or at the side of the garbage basket 4. In short, the first drain outlet 2 and the second drain outlet 5 are located near the bottom when the machine lifts out water. In this way, when the automatic cleaning device of the water tank is lifted out, the water in the machine body and the water in the garbage basket 3 can be discharged all at once from the first drain outlet 2 and the second drain outlet 5 located at the bottom or side under the action of gravity, without the need for additional power drive, and minimizing the residue of water inside the machine body.

[0045] In one example, the first drain outlet 2 is located on the side of the housing 1 near the bottom, and the second drain outlet 5 is located on the side of the garbage basket 4 near the bottom of the housing 1.

[0046] To facilitate the complete drainage of water from the automatic water cleaning device, the first drain outlet 2 is located on the side of the housing 1 near the bottom. For example, the first drain outlet 2 can be located on the lower side of the housing 1, or on the area where the side of the housing 1 meets the bottom. The second drain outlet 5 is located on the side of the garbage basket 4 near the bottom of the housing 1. For example, the second drain outlet 5 can be located on the lower side of the garbage basket 4, or on the area where the side of the garbage basket 4 meets the bottom of the housing 1. This way, when the machine is lifted out of the water, the first drain outlet 2 and the second drain outlet 5 are at their lowest points, accelerating the drainage of water from inside the machine and ensuring that as much water as possible is drained from inside the machine. This prevents water from leaking out when the machine is placed on the ground or a base station, thus avoiding any impact on the user experience.

[0047] It should be understood that this application does not limit the specific locations of the first drain outlet 2 and the second drain outlet 5. Those skilled in the art can set them according to actual use needs, as long as the technical principles of this application can be realized.

[0048] A water flow separator 7 is provided between the housing 1 and the garbage basket 4. The water flow separator 7 is used to prevent water from flowing between the housing 1 and the garbage basket 4 from entering the garbage basket 3 from the second drain outlet 5.

[0049] The water flow separator 7 is disposed around the second drain outlet 5.

[0050] like Figure 1A As shown, there is a space, namely the first space 8, between the shell 1 and the garbage basket 4. Because the shell 1 has gaps or vents, when the machine is in water, external water may enter the first space 8 through these gaps or vents. To quickly drain the water from the first space 8 when the machine is lifted out of the water, the first space 8 can be connected to the first drain outlet 2 on the shell 1. However, the first drain outlet 2 and the second drain outlet 5 are positioned opposite each other. When the machine is in water, water from the first space 8 can also flow into the garbage basket 3 through the second drain outlet 5, affecting the sealing of the filter channel of the garbage basket 3 and thus the pump's suction effect. To address this, this embodiment of the specification designs a water flow separator 7, such as... Figure 1A , Figure 1B and Figure 3As shown, the water flow separator 7 is used to prevent water from flowing into the garbage basket 3 through the second drain outlet 5 from the space between the housing 1 and the garbage basket 4, i.e., the first space 8. Exemplarily, the water flow separator 7 may include two components: a first component is disposed on the outer wall of the garbage basket 4, and a second component is disposed on the inner wall of the housing 1. The first component and the second component cooperate with each other to prevent water from flowing into the garbage basket 4 through the second drain outlet 5. Figure 1B As shown, a protrusion can be provided on the outer wall of the garbage basket holding compartment 4, and a groove can be provided on the inner wall of the shell 1 at the position opposite to the protrusion. The protrusion and the groove cooperate with each other to form a compact waterproof structure, thereby preventing water from flowing between the shell 1 and the garbage basket holding compartment 4 from entering the garbage basket 3 through the second drain outlet 5.

[0051] It is understood that the water flow separator 7 can be arranged around the second drain outlet 5, thereby providing a water flow blocking effect on all sides of the second drain outlet 5. It should be noted that the above description of the water flow separator 7 is merely exemplary, and the scope of protection of this application is not limited thereto. Any design that can realize the technical principle of the water flow separator of this application is within the scope of protection of this application.

[0052] To better achieve the blocking effect of the water flow separator 7, the water flow separator 7 is arranged around the second drain outlet 5. In this way, the water flow separator 7 is arranged in a ring on the second drain outlet 5, which can effectively block the water flow in the space between the shell 1 and the garbage basket receiving compartment 4, i.e., the first space 8, from entering the garbage basket receiving compartment 4 and the garbage basket 3 from the second drain outlet 5.

[0053] like Figure 2 and Figure 4As shown, in order to quickly drain the water in the first space 8 when the machine lifts the water surface, the first drain outlet 2 on the housing 1 can be set to be larger than the second drain outlet 5. Simultaneously, a water flow separator 7 is used to divide the first drain outlet 2 into a first part 201 and a second part 202. The first part 201 can communicate with the first space 8 between the housing 1 and the garbage basket holding compartment 4, while the second part 202 is directly opposite and communicates with the second drain outlet 5. Thus, when the machine lifts the water, the one-way valve 6 opens the first drain outlet 2, allowing the water in the first space 8 to drain from the first part 201 of the first drain outlet 2, while the water in the garbage basket 3 and the garbage basket holding compartment 4 can drain from the second part 202 of the first drain outlet 2. When the machine is in water, the one-way valve 6 closes the first outlet 2 and the second outlet 5, preventing external water from entering the first outlet 2, and thus the second outlet 5 and the trash basket 3. Water in the first space 8 is also prevented from entering the second outlet 5 by the water flow separator 7, thus sealing the filter channel of the trash basket 5. This effectively ensures that the trash basket holding chamber 4 gathers water, ensuring that under the suction of the water pump, water will only enter the trash basket 3 from the trash basket inlet at the bottom of the machine, improving the machine's suction effect.

[0054] In addition, other drain outlets can be provided on the housing 1, and similarly, other drain outlets can be provided on the garbage basket 4 to increase the machine's drainage speed.

[0055] For example, Figure 2 as well as Figures 4-6 As shown, a third drain outlet 9 is also provided on the housing 1. The third drain outlet 9 can be located at the bottom of the machine housing, and its position can be offset from that of the garbage basket receiving compartment 4 to quickly drain water from the space outside the garbage basket receiving compartment 4 in the housing 1. Of course, if there is space in the housing corresponding to the bottom of the garbage basket receiving compartment 4, the third drain outlet 9 can also be located at the bottom of the garbage basket receiving compartment 4. Simultaneously, a fourth drain outlet 10 can also be provided on the garbage basket receiving compartment 4. For example, as... Figure 3 As shown, the fourth drain outlet 10 is set at the bottom of the garbage basket holding compartment 4. The fourth drain outlet 10 is connected to the third drain outlet 9, which can improve the drainage speed of the garbage basket holding compartment 4.
