Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical appliances, and in particular to a washing structure and an electrical appliance. Background Technology
[0002] In existing technologies, the water system of washing appliances has numerous connecting pipes, leading to a greater risk of leakage. Furthermore, each component requires independently designed mounting brackets, positioning structures, and fixing components, making the assembly process cumbersome and complex. This not only increases the difficulty of manual operation and the probability of errors but also results in low production efficiency and increased manufacturing costs. In addition, the decentralized component layout lacks systematic planning, and each component is forced to reserve a large amount of redundant space to accommodate its independent mounting structure. This results in a loose internal structure, making it difficult to achieve miniaturization and failing to meet the space-efficient needs of modern homes. Utility Model Content
[0003] Therefore, it is necessary to provide a washing structure and appliance that addresses the problem of numerous connecting pipes and complex component installation structures in the internal water system of washing appliances.
[0004] A washing structure includes: an inner tank, the inner tank having a water collection tank, a first mounting port, and an inner tank outlet, the first mounting port being located at the bottom of the water collection tank; a planar filter, the planar filter being disposed on the inner tank and covering the water collection tank; and a water collector, the water collector including a water collection housing, a washing pump mounting housing, and a drain pump mounting housing, the water collection housing being disposed on the inner tank and adapted to be installed with the first mounting port, the water collection housing having a water collector cavity communicating with the water collection tank, the washing pump mounting housing and the drain pump mounting housing both being disposed on the water collection housing, the washing pump mounting housing having a washing pump inlet communicating with the water collector cavity, the washing pump mounting housing being used to connect with a washing pump, and the drain pump mounting housing having a drain pump inlet communicating with the water collector cavity, the drain pump mounting housing being used to connect with a drain pump; the water collection housing, the washing pump mounting housing, and the drain pump mounting housing are integrally formed.
[0005] The aforementioned disclosure describes a washing structure. In traditional washing appliances, the numerous connecting pipes in the water system lead to multiple potential leakage points, and each component requires a separate mounting structure for fixation, resulting in a complex installation structure, unreasonable component distribution, and a large overall size. This application, however, integrates the water collection shell, washing pump mounting shell, and drain pump mounting shell into a single, unified cavity structure, completely eliminating intermediate connecting pipes. Water flow can directly connect to the inlets of the washing pump and drain pump through the water collection chamber of the water collection shell, forming an uninterrupted, straight-through water path. This avoids problems such as pipe bends and loose connections common in traditional systems, significantly reducing water flow resistance and leakage risks, and making the washing water circulation and wastewater discharge processes more stable and efficient. Furthermore, the integrated molding process of the water collection shell, washing pump mounting shell, and drain pump mounting shell eliminates any physical seams between functional modules, fundamentally eliminating the sealing shortcomings of traditional structures. The water collection trough at the bottom of the inner tank serves as the central convergence point for the washing water. Its sloping bottom design guides the water quickly to the first mounting port at the bottom, preventing water from stagnating and forming dead zones. This design shortens the water flow path from the inner tank to the collector, and, in conjunction with the collector's cavity, enables rapid collection and circulation of the washing water, improving washing efficiency. The first mounting port is located at the bottom of the water collection trough and is fitted to the collector's housing, forming a vertical, straight-through water flow channel. This layout allows the washing water to enter the collector's cavity directly through the flat filter, water collection trough, and first mounting port without needing additional piping. This further reduces water flow resistance and leakage risks caused by horizontal piping connections in traditional structures, while also simplifying the assembly process between the inner tank and the collector.
[0006] In one embodiment, the planar filter has a second mounting port and also includes a cylindrical filter. The cylindrical filter is disposed on the planar filter and passes through the second mounting port. The portion of the cylindrical filter passing through the second mounting port extends into the water collector cavity after passing through the first mounting port. By providing a second mounting port on the planar filter and placing the cylindrical filter on top, a multi-layered filtration effect can be achieved due to the multiple micropores on the planar filter combined with the cylindrical filter. Firstly, large particulate impurities in the washing water are intercepted, preventing them from entering the water collector cavity. This pre-filtration reduces the burden on the subsequent cylindrical filter, extending its service life. The combination of the cylindrical and planar filters adopts a vertical through-flow layout. The cylindrical filter extends directly into the water collector cavity through the second and first mounting ports, requiring no additional horizontal space. This design extends the filtration function from a planar plane to a three-dimensional space, significantly increasing the filtration area and efficiency without increasing the overall lateral dimensions of the machine, making it particularly suitable for compact washing equipment with stringent space requirements. The tight fit between the cylindrical and planar filters, forming a sealed connection through the second mounting port, prevents water leakage during the filtration process. Meanwhile, the portion of the cylindrical filter extending into the water collector cavity forms a ring-shaped water path with the inner wall of the water collector, further optimizing the water flow path and reducing the risk of leakage caused by traditional multi-component connections.
[0007] In one embodiment, a washing pump is also included. The washing pump is mounted on the washing pump mounting housing and located at the washing pump inlet. The washing pump or the washing pump mounting housing has a washing pump outlet. The washing pump inlet, the washing pump outlet, and the inner tank outlet are sequentially connected. By sequentially connecting the washing pump inlet, the washing pump outlet, and the inner tank outlet, the washing pump inlet is directly connected to the water collector cavity, ensuring that filtered clean washing water is drawn into the pump body via the shortest path, avoiding pressure loss caused by traditional long pipelines. The direct connection between the washing pump outlet and the inner tank outlet forms an uninterrupted sealed channel, eliminating the risk of leakage from traditional pipeline connections at the source, while also simplifying assembly and reducing costs.
[0008] In one embodiment, a drain pump is also included, which is mounted on the drain pump mounting housing and located at the drain pump inlet. By mounting the drain pump on the drain pump mounting housing and directly connecting the drain pump inlet to the water collector cavity, impurities and wastewater in the water collector can be quickly extracted and discharged from the equipment after washing or rinsing. This structure also reduces piping connections, thereby reducing potential leaks and assembly steps, thus lowering costs.
[0009] In one embodiment, a heating element is also included. The inner liner has a heating element mounting port, and the heating element is disposed on the inner liner and located at the heating element mounting port. By providing a heating element mounting port in the inner liner, and placing the heating element at the mounting port, the heating element is independently mounted on the water collection tank. This design breaks away from the traditional layout pattern of embedding the heating element inside a complex cavity, effectively avoiding the structural bulkiness caused by the heating element and other components occupying space. By combining the heating element with the water collection tank, the internal space of the entire unit can be re-optimized and allocated, eliminating the need to increase the overall size of the unit to accommodate the heating element, thereby further reducing the overall size of the unit while ensuring the normal operation of the heating function.
[0010] In one embodiment, the heating element mounting port is located at the bottom of the water collection tank, adjacent to the first mounting port, and the flat filter covers the heating element. By placing the heating element mounting port at the bottom of the water collection tank and adjacent to the first mounting port, the distance between the heating element and the water collector is shortened, reducing the path of the washing water from the water collector to the heating element. During heating, the water flow can reach the heating area more quickly, reducing heat loss during transmission and improving heating efficiency. Simultaneously, the flat filter covering the heating element effectively blocks impurities in the washing water during washing, preventing impurities from adhering to the surface of the heating element and forming dirt, thus preventing dirt accumulation from affecting the heating effect and further ensuring stable heating efficiency. Moreover, placing the heating element mounting port on the water collection tank allows the heating element to fully utilize the space around the water collection tank without occupying additional space inside the inner tank. The design adjacent to the first mounting port allows the heating element and other components such as the water collector to form a compact combination, resulting in a more rational and orderly layout of each component. The flat filter covers the heating element, which not only provides protection but also avoids the need for a separate protective structure for the heating element, thus reducing the overall size of the machine and improving space utilization.
[0011] In one embodiment, the inner tank outlet is adjacent to the water collection tank, and the washing structure has a door. The distance from the water collection tank to the door is less than the distance from the inner tank outlet to the door. By placing the inner tank outlet adjacent to the water collection tank, the flow of washing water from the inner tank into the water collection tank is shortened. Washing water can flow into the water collection tank more quickly and smoothly, reducing resistance and time loss during water flow, creating favorable conditions for subsequent circulating washing or drainage via the water collector. The design of the water collection tank being closer to the door allows users to more easily access the water collection tank when cleaning or inspecting the equipment. As a key component for collecting washing water and impurities, the water collection tank requires regular cleaning and maintenance. This layout reduces the difficulty and obstacles for user operation and lowers the time cost of cleaning and maintenance.
[0012] In one embodiment, the washing pump mounting housing is disposed on the inner tank outlet, and the washing pump inlet, the washing pump mounting housing, and the inner tank outlet are sequentially connected. By placing the washing pump mounting housing on the inner tank outlet, the washing pump inlet, the washing pump mounting housing, and the inner tank outlet are sequentially connected. This design eliminates the circuitous route of traditional hose connections, allowing washing water to be delivered to the inner tank outlet without passing through bends in the pipes. This ensures that the washing pump can deliver filtered clean water to the inner tank more efficiently, improving spray pressure and uniformity, thereby enhancing stain removal ability and shortening washing time.
[0013] In one embodiment, the washing pump mounting housing and the drain pump mounting housing are respectively located on opposite sides of the water collection housing. The extension line of the central axis of the washing pump mounting housing coincides with the extension line of the central axis of the drain pump mounting housing, and both extension lines are perpendicular to the extension line of the central axis of the water collection housing. By utilizing the design where the extension lines of the central axes of the washing pump mounting housing and the drain pump mounting housing coincide and are perpendicular to the extension line of the central axis of the water collection housing, uniform load distribution and counterweight balance are achieved. During the operation of the washing equipment, the vibrations and forces generated by the washing pump and the drain pump are transmitted evenly to the water collection housing and the entire machine structure through the symmetrically distributed mounting housings. This effectively avoids local stress concentration caused by uneven load distribution, preventing instability such as tilting and shaking of the equipment. Whether it is the water flow impact when the washing pump is running at high speed or the reaction force generated by the rapid drainage of the drain pump, they can be mutually canceled out under this balanced layout, thereby greatly improving the overall stability and extending the service life of the equipment. Furthermore, the separate mounting housings on both sides with their central axes specially aligned make the paths for washing water and wastewater clearer and more independent, greatly reducing interference between water flows. The washing pump mounting housing guides the washing water into the washing pump for circulation, while the drain pump mounting housing is specifically used to discharge filtered impurities. The two are located on opposite sides of the water collection housing, allowing the water to flow in their own paths and preventing problems such as unstable water pressure and reduced water flow efficiency caused by water mixing and backflow.
[0014] In one embodiment, the washing pump has a washing pump outlet, and the extension line of the central axis of the washing pump inlet is perpendicular to the extension line of the central axis of the washing pump outlet. By utilizing this perpendicular design, when washing water enters the washing pump from the inlet, the vertically deflecting inlet allows the water flow to exit directly without navigating complex bends or circuitous paths. According to fluid mechanics principles, during pipeline transport, the more bends and the longer the path, the greater the friction and local resistance experienced by the water flow, and the greater the water pressure loss. The vertical design significantly shortens the water path length, reduces unnecessary water flow deflections, lowers frictional losses between the water flow and the pipe wall, and maximizes water pressure stability. This means the washing pump can deliver water to the inner tank outlet with lower energy consumption and higher pressure and flow rate, providing strong water flow power for the washing process and improving the washing effect. By utilizing a design where the extended lines of the washing pump's inlet center axis are perpendicular to each other, the vertically oriented inlet design allows water to flow directly out without navigating complex bends or detours when entering the pump. According to fluid mechanics principles, the more bends and the longer the path in a pipeline, the greater the friction and local resistance experienced by the water flow, leading to increased pressure loss. The vertical design significantly shortens the water path, reduces unnecessary flow detours, and minimizes frictional losses between the water and the pipe wall, maximizing water pressure stability. This means the washing pump can deliver water to the inner tank outlet with higher pressure and velocity at lower energy consumption, providing strong water flow power for the washing process and improving washing performance.
[0015] In one embodiment, an inlet pipe is provided between the water collection housing and the washing pump mounting housing, and an outlet pipe is provided in the washing pump mounting housing. The inlet pipe is located on the extension line of the central axis of the washing pump mounting housing, and the extension line of the central axis of the outlet pipe is perpendicular to the extension line of the central axis of the inlet pipe. By placing the inlet pipe on the extension line of the central axis of the washing pump mounting housing, this arrangement allows water to flow smoothly into the washing pump mounting housing in a straight line, reducing resistance and energy loss when the water enters. According to fluid mechanics principles, a straight water flow path makes the water flow more stable and reduces turbulence caused by water turning. Furthermore, the extension line of the central axis of the outlet pipe is perpendicular to the inlet pipe, so that when the water flows out of the washing pump mounting housing, it does not need to make multiple bends, avoiding pressure loss caused by bends and ensuring that the water can be output at a higher pressure and velocity. The combination of these two features significantly shortens the water path from the water collection housing into the washing pump and then out, reducing water pressure loss, improving the working efficiency of the washing pump, providing a stronger and more stable water flow force for the washing process, and effectively improving the washing effect.
[0016] In one embodiment, the cylindrical filter includes a first filter section, a second filter section, a third filter section, a fourth filter section, and an annular housing. The second filter section is disposed on the planar filter, the first and third filter sections are disposed on the second filter section, and the fourth filter section is disposed on the third filter section. The horizontal height of the first filter section is greater than the horizontal height of the planar filter. The water collector has a water collector cavity, the third filter section is located in the water collector cavity, and the annular housing is disposed on the third filter section. The annular housing abuts against the inner wall of the water collector and divides the water collector cavity into a first cavity and a second cavity. The first cavity communicates with the inlet of the washing pump, and the second cavity communicates with the inlet of the drain pump. By laying the second filter section on top of the planar filter as a primary filtration barrier, larger impurities in the washing water can be quickly intercepted. The first filter section is higher than the planar filter, which can preferentially capture impurities in the water flowing into the second filter section from above, preventing these impurities from directly entering the water collector cavity and reducing the subsequent filtration burden. The third filtration section extends deep into the water collector cavity, performing secondary deep filtration on the water entering the cavity, effectively removing smaller particulate impurities. The fourth filtration section, located above the third, further filters these tiny particles, ensuring a high level of cleanliness for the water entering the washing and drain pumps. This four-stage filtration system significantly improves the interception efficiency of impurities in the washing water, protecting the pump body from wear and extending equipment lifespan, while also ensuring the cleanliness of the washing water and enhancing washing performance. The first, second, third, and fourth filtration sections are manufactured using a one-piece molding process, effectively resisting the strong scouring of water during washing and the vibrations generated by pump operation. This reduces the risk of impurity leakage due to structural damage, ensuring long-term stable filtration performance. Simultaneously, the robust structure prevents deformation of the filter during installation and disassembly due to external forces, ensuring precise fit with components such as the planar filter and the water collector cavity, thus improving the overall stability of the washing structure. The placement of the annular housing within the third filtration section, abutting against the inner wall of the water collector, has a significant effect. During drainage, the water flow must return through the third filter hole, achieving secondary filtration compared to the situation where the annular shell does not contact the water collector shell. When sewage enters the second chamber of the water collector, under the action of the drainage pump, the water flow must pass through the third filter hole before entering the channel connected to the drainage pump inlet. At this time, the third filter hole can again intercept residual impurities in the sewage, including tiny particles and fibers that may have been missed in the previous filtration process. This secondary filtration mechanism effectively improves the filtration accuracy of the entire washing structure, reduces problems such as sewer blockage caused by impurities discharged with sewage, and also reduces wear on drainage pipes caused by impurities, extending the service life of the drainage system. At the same time, the annular shell divides the water collector chamber into the first and second chambers, optimizing the water flow path.Washing water collects in the first chamber of the water collector. Through its connection to the inlet of the washing pump, it enters the pump via the shortest and most direct path, reducing water flow detours and energy loss within the chamber and improving the pump's pumping efficiency. Impurities, on the other hand, concentrate in the second chamber and are quickly discharged by the drain pump through its connection to the drain pump inlet, preventing impurities from accumulating within the chamber and ensuring efficient and smooth drainage.
[0017] In one embodiment, the planar filter has multiple micropores. The outer wall of the third filter section and the inner wall of the water collector form a filtration water path. The multiple micropores, the water collection tank, the filtration water path, and the washing pump inlet form a first channel. The first filter section has a first filter hole, the second filter section has a second filter hole, and the third filter section has a third filter hole. The number of the first, second, and third filter holes is multiple. The multiple first, second, and third filter holes and the washing pump inlet form a second channel. The fourth filter section has multiple fourth filter holes. The multiple first, second, and fourth filter holes and the drain pump inlet form a third channel. The multiple micropores, the water collection tank, the filtration water path, the third filter hole, the multiple fourth filter holes, and the drain pump inlet form a fourth channel. By utilizing planar and cylindrical filters to construct first, second, third, and fourth channels through micropores and filter holes, the washing structure gains highly efficient and precise filtration capabilities and water flow management advantages. The first channel, utilizing multiple micropores in the planar filter, combined with a water collection tank, a filtration path formed by the outer wall of the third filter section and the inner wall of the water collector, and the washing pump inlet, can preferentially intercept larger impurities in the washing water. These larger impurities are blocked on the surface of the planar filter, preventing them from entering the subsequent water path and avoiding clogging or wear on the washing pump, ensuring stable operation. The second channel, composed of multiple first, second, and third filter holes in the cylindrical filter and the washing pump inlet, focuses on filtering smaller particulate impurities. As water flows through, these smaller particles are intercepted layer by layer by the filter holes, resulting in higher cleanliness of the water entering the washing pump, ensuring efficient operation of the washing pump, while also improving the purity of the washing water and enhancing the washing effect. The third and fourth channels, with the help of multiple fourth filter holes in the fourth filter section, work in conjunction with other filter holes and the drain pump inlet to undertake the important task of removing tiny impurities. The fourth filter hole has a precisely designed aperture that ensures the smooth discharge of minute impurities while effectively preventing particles that could affect the normal operation of the drainage pump's rotating impeller from entering. This not only avoids the risk of the drainage pump's rotating impeller becoming stuck, preventing serious malfunctions such as overload and burnout of the drainage pump motor caused by impeller jamming, but also reduces frictional wear between the impeller and impurities, effectively extending the service life of the drainage pump.
[0018] The second aspect of this application discloses an electrical appliance, which includes: the washing structure described above; and an appliance body, wherein the washing structure is disposed on the appliance body.
[0019] The second aspect disclosed above discloses an electrical appliance in which the washing structure is set on the main body of the appliance. The water collector adopts an integrated molding process of water collection shell, washing pump mounting shell and drain pump mounting shell, which abandons the traditional method of splicing multiple parts and connecting multiple pipelines, eliminates many potential water leakage points from the root, minimizes the risk of water leakage, and provides users with stable and reliable use guarantee.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0040] The washing structure and electrical appliance of this utility model are described below with reference to the accompanying drawings.
[0041] Example 1
[0042] like Figures 1 to 10 As shown, this embodiment discloses a washing structure, including: an inner tank 1, which has a water collection tank 101, a first mounting port 102, and an inner tank outlet 103, the first mounting port 102 being located at the bottom of the water collection tank 101; a planar filter 2, which is disposed on the inner tank 1 and covers the water collection tank 101; and a water collector 3, which includes a water collection housing 31, a washing pump mounting housing 32, and a drain pump mounting housing 33, the water collection housing 31 being disposed on the inner tank 1 and adapted to the first mounting port 102, and the water collection housing 31 having a water collector cavity. 303, the water collector cavity 303 is connected to the water collection tank 101. The washing pump mounting shell 32 and the drain pump mounting shell 33 are both installed on the water collector shell 31. The washing pump mounting shell 32 has a washing pump inlet 301 that communicates with the water collector cavity 303. The washing pump mounting shell 32 is used to connect with the washing pump 5. The drain pump mounting shell 33 has a drain pump inlet 302 that communicates with the water collector cavity 303. The drain pump mounting shell 33 is used to connect with the drain pump 6. The water collector shell 31, the washing pump mounting shell 32 and the drain pump mounting shell 33 are integrally formed.
[0043] This application discloses a washing structure. In traditional washing appliances, the numerous connecting pipes in the water system lead to a high risk of leakage, and each component requires a separate mounting structure for fixation, resulting in a complex installation structure, unreasonable component distribution, and a large overall size. This application, however, integrates the water collection housing 31, washing pump mounting housing 32, and drain pump mounting housing 33 into a single integrated cavity structure, completely eliminating intermediate connecting pipes. Water can directly flow through the water collection chamber 303 of the water collection housing 31 to the inlets of the washing pump 5 and drain pump 6, forming an uninterrupted, straight-through water path. This avoids problems such as pipe bends and loose connections, significantly reducing water flow resistance and leakage risk, making the washing water circulation and wastewater discharge process more stable and efficient. Furthermore, the integrated molding process of the water collection housing 31, washing pump mounting housing 32, and drain pump mounting housing 33 eliminates any physical seams between functional modules, fundamentally eliminating the sealing shortcomings of traditional structures. The water collection trough 101 at the bottom of the inner tank 1 serves as the center for collecting washing water. Its sloping bottom design guides the water to flow quickly to the first mounting port 102 at the bottom, preventing water from stagnating and forming dead zones. This design shortens the water flow path from the inner tank 1 to the water collector 3. Combined with the water collector cavity 303 of the water collector 3, it enables rapid collection and circulation of washing water, improving washing efficiency. The first mounting port 102 is located at the bottom of the water collection trough 101 and is fitted to the water collection housing 31 of the water collector 3, forming a vertical, straight-through water flow channel. This layout allows the washing water to enter the water collector cavity 303 of the water collector 3 directly through the flat filter 2, the water collection trough 101, and the first mounting port 102 without needing additional piping. This further reduces water flow resistance and leakage risks caused by horizontal pipe connections in traditional structures, while also simplifying the assembly steps of the inner tank and the water collector.
[0044] like Figure 3 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the planar filter 2 is provided with a second mounting port 201, and also includes a cylindrical filter 4. The cylindrical filter 4 is disposed on the planar filter 2 and passes through the second mounting port 201. The portion of the cylindrical filter 4 passing through the second mounting port 201 extends into the water collector cavity 303 after passing through the first mounting port 102. By providing a second mounting port 201 on the planar filter 2 and placing the cylindrical filter 4 on it, a multi-layer filtration effect can be achieved by combining the planar filter 2 with the cylindrical filter 4, which has multiple micropores. First, large particulate impurities in the washing water are intercepted, preventing them from entering the water collector cavity 303 of the water collector 3. This pre-filtration reduces the burden on the subsequent cylindrical filter 4 and extends its service life. The combination of the cylindrical filter 4 and the planar filter 2 adopts a vertical through-layout layout. The cylindrical filter extends directly into the water collector cavity 303 of the water collector through the second mounting port 201 and the first mounting port 102, without requiring additional horizontal space. This design extends the filtration function from a planar plane to a three-dimensional space, significantly increasing the filtration area and efficiency without increasing the overall lateral dimensions of the machine. It is particularly suitable for compact washing equipment with limited space requirements. The tight fit between the cylindrical filter 4 and the planar filter 2, forming a sealed connection through the second mounting port 201, prevents water leakage during filtration. Simultaneously, the portion of the cylindrical filter extending into the water collector cavity 303 forms a ring-shaped water path with the inner wall of the water collector, further optimizing the water flow path and reducing the risk of leakage caused by traditional multi-component connections.
[0045] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further includes a washing pump 5, which is mounted on the washing pump mounting housing 32 and located at the washing pump inlet 301. The washing pump 5 or the washing pump mounting housing 32 has a washing pump outlet 501. The washing pump inlet 301, the washing pump outlet 501, and the inner tank outlet 103 are sequentially connected. By sequentially connecting the washing pump inlet 301, the washing pump outlet 501, and the inner tank outlet 103, the washing pump inlet 301 is directly connected to the water collector cavity 303, ensuring that the filtered clean washing water is drawn into the pump body through the shortest path, avoiding pressure loss caused by traditional long pipeline water suction. The washing pump outlet 501 and the inner tank outlet 103 are directly connected, forming an uninterrupted sealed channel, eliminating the risk of leakage from traditional pipeline connections at the source, while also simplifying the assembly process and reducing costs.
[0046] like Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further includes a drain pump 6, which is mounted on the drain pump mounting housing 33 and located at the drain pump inlet 302. By mounting the drain pump 6 on the drain pump mounting housing 33 and directly connecting it to the water collector cavity 303 through the drain pump inlet 302, impurities and sewage in the water collector can be quickly extracted and discharged from the equipment after washing or rinsing. This structure also reduces pipe connections, thereby reducing leakage points and assembly steps, thus lowering costs.
[0047] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further includes a heating element 7. The inner liner 1 has a heating element mounting port 104, and the heating element 7 is disposed on the inner liner 1 and located at the heating element mounting port 104. By providing a heating element mounting port 104 in the inner liner 1, and placing the heating element 7 at the mounting port, the heating element 7 is independently disposed on the water collection tank 101. This design breaks away from the traditional layout mode of embedding the heating element 7 inside a complex cavity, effectively avoiding the structural bulkiness caused by the heating element 7 and other components occupying space. By combining the heating element 7 with the water collection tank 101, the internal space of the entire machine can be re-optimized and allocated, without needing to increase the overall volume of the machine to accommodate the heating element 7, thereby further reducing the overall volume of the machine while ensuring the normal operation of the heating function.
[0048] like Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heating element mounting port 104 is located at the bottom of the water collection tank 101, the heating element mounting port 104 is arranged adjacent to the first mounting port 102, and the flat filter 2 covers the heating element 7. By setting the heating element mounting port 104 at the bottom of the water collection tank 101 and adjacent to the first mounting port 102, the distance between the heating element 7 and the water collector 3 is shortened, reducing the path of the washing water from the water collector to the heating element. During the heating process, the water flow can reach the heating area more quickly, reducing heat loss during transmission and improving heating efficiency. At the same time, the flat filter 2 covers the heating element 7, and during the washing process, the flat filter can effectively block impurities in the washing water, preventing impurities from adhering to the surface of the heating element and forming dirt, preventing the heating effect from being affected by dirt accumulation, and further ensuring the stability of heating efficiency. Moreover, the heating element 7 mounting port is set on the water collection tank 101, so that the heating element 7 can make full use of the space around the water collection tank 101 without occupying other space inside the inner tank. The design adjacent to the first mounting port 102 allows the heating element 7 and other components such as the water collector 3 to form a compact combination, resulting in a more rational and orderly layout of each component. The flat filter 2 covers the heating element 7, which not only provides protection but also avoids the need for a separate protective structure for the heating element, thus reducing the overall size of the unit and improving space utilization.
[0049] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner tank outlet 103 and the water collection tank 101 are arranged adjacent to each other, the washing structure is provided with a door, and the distance from the water collection tank 101 to the door is less than the distance from the inner tank outlet 103 to the door. By aligning the inner tank outlet 103 with the water collection tank 101, the flow of washing water from the inner tank into the water collection tank can be shortened. The washing water can flow into the water collection tank more quickly and smoothly, reducing the resistance and time loss of water flow during transmission, creating favorable conditions for subsequent circulating washing or drainage through the water collector 3. The design of the water collection tank 101 being closer to the door allows users to more conveniently access the water collection tank 101 when cleaning and inspecting the equipment. As a key part for collecting washing water and impurities, the water collection tank 101 requires regular cleaning and maintenance. This layout reduces the difficulty and obstacles for user operation and lowers the time cost of cleaning and maintenance.
[0050] like Figure 4 , Figure 8 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the washing pump mounting housing 32 is disposed on the inner tank outlet 103, and the washing pump inlet 301, the washing pump mounting housing 32, and the inner tank outlet 103 are sequentially connected. By disposing of the washing pump mounting housing 32 on the inner tank outlet 103, the washing pump inlet 301, the washing pump mounting housing 32, and the inner tank outlet 103 are sequentially connected. This design eliminates the circuitous route of traditional hose connections, allowing washing water to be delivered to the inner tank outlet 103 without passing through a bend in the pipe. This ensures that the washing pump 5 can deliver filtered clean water to the inner tank 1 in a more efficient manner, improving spray pressure and uniformity, thereby enhancing stain removal ability and shortening washing time.
[0051] like Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the washing pump mounting housing 32 and the drain pump mounting housing 33 are respectively disposed on both sides of the water collection housing 31. The extension line of the central axis of the washing pump mounting housing 32 coincides with the extension line of the central axis of the drain pump mounting housing 33, and both the extension lines of the central axes of the washing pump mounting housing 32 and the drain pump mounting housing 33 are perpendicular to the extension line of the central axis of the water collection housing 31. By utilizing the design that the extension lines of the central axes of the washing pump mounting housing 32 and the drain pump mounting housing 33 coincide and are perpendicular to the extension line of the central axis of the water collection housing 31, a uniform load distribution and counterweight balance are achieved. During the operation of the washing equipment, the vibration and force generated by the washing pump and the drain pump are transmitted to the water collection housing 31 and the entire machine structure in a balanced manner through the symmetrically distributed mounting housings. This effectively avoids local stress concentration caused by uneven load distribution and prevents unstable phenomena such as tilting and shaking of the equipment. Both the water flow impact during the high-speed operation of the washing pump and the reaction force generated by the rapid drainage of the drain pump can be mutually canceled out by this balanced layout, thereby greatly improving the overall stability and extending the service life of the equipment. Furthermore, the separate mounting housings on both sides with their central axes specially aligned make the paths for washing water and wastewater clearer and more independent, greatly avoiding interference between water flows. The washing pump mounting housing 32 guides the washing water into the washing pump 5 for circulation washing, while the drain pump mounting housing 33 is specifically used to discharge filtered impurities. These two housings are located on opposite sides of the water collection housing 31, allowing the water flows to follow their own paths and preventing problems such as unstable water pressure and reduced water flow efficiency caused by water mixing and backflow.
[0052] like Figure 8 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the washing pump 5 is provided with a washing pump outlet 501, and the extension line of the central axis of the washing pump inlet 301 is perpendicular to the extension line of the central axis of the washing pump outlet 501. By utilizing the design that the extension lines of the central axes of the washing pump inlet 301 and the washing pump outlet 501 are perpendicular to each other, when washing water enters the washing pump 5 from the washing pump inlet 301, the vertically turning design of the washing pump inlet 301 allows the water flow to be discharged directly without having to go through complex bends or detours. According to the principles of fluid mechanics, during pipeline transportation, the more bends and the longer the path, the greater the friction and local resistance experienced by the water flow, and the greater the water pressure loss will be. The vertical design significantly shortens the water path length, reduces unnecessary water flow turning, reduces frictional losses between the water flow and the pipe wall, and maintains water pressure stability to the greatest extent. This means that the washing pump 5 can deliver water to the inner tank outlet 103 with higher pressure and flow rate at a lower energy consumption, providing strong water flow power for the washing process and improving the washing effect.
[0053] like Figure 4 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: an inlet pipe is provided between the water collection housing 31 and the washing pump mounting housing 32, and an outlet pipe is provided in the washing pump mounting housing 32. The inlet pipe is located on the extension line of the central axis of the washing pump mounting housing 32, and the extension line of the central axis of the outlet pipe is perpendicular to the extension line of the central axis of the inlet pipe. By setting the inlet pipe on the extension line of the central axis of the washing pump mounting housing 32, this arrangement allows water to flow smoothly into the washing pump mounting housing 32 in a straight line, reducing resistance and energy loss when the water flows in. According to the principles of fluid mechanics, a straight water flow path can make the water flow more stable and reduce turbulence caused by water flow turning. Furthermore, the extension line of the central axis of the outlet pipe is perpendicular to the inlet pipe, so that when the water flows out of the washing pump mounting housing 32, it does not need to bend multiple times, avoiding pressure loss caused by bends and ensuring that the water can be output at a higher pressure and flow rate. The combination of these two components greatly shortens the water path from the water collection housing 31 into the washing pump 5 and then out, reducing water pressure loss, improving the working efficiency of the washing pump 5, providing a stronger and more stable water flow for the washing process, and effectively improving the washing effect.
[0054] like Figure 5 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the cylindrical filter 4 includes a first filter section 41, a second filter section 42, a third filter section 43, a fourth filter section 44, and an annular housing 45. The second filter section 42 is disposed on the planar filter 2, the first filter section 41 and the third filter section 43 are disposed on the second filter section 42, and the fourth filter section 44 is disposed on the third filter section 43. The horizontal height of the first filter section 41 is greater than the horizontal height of the planar filter 2. The water collector 3 is provided with a water collector cavity 303, the third filter section 43 is located in the water collector cavity 303, and the annular housing 45 is disposed on the third filter section 43. The annular housing 45 abuts against the inner sidewall of the water collector 3, and the annular housing 45 divides the water collector cavity 303 into a first cavity and a second cavity. The first cavity is connected to the inlet 301 of the washing pump, and the second cavity is connected to the inlet 302 of the drain pump. By laying the second filter section 42 on the planar filter 2 as a primary filtration barrier, larger impurities in the washing water can be quickly intercepted. The first filter section 41 is higher than the planar filter 2, allowing it to preferentially capture impurities in the water flowing into the second filter section 42 from above, preventing these impurities from directly entering the water collector cavity 303 and reducing the burden on subsequent filtration. The third filter section 43 extends into the water collector cavity 303, performing secondary deep filtration on the water entering the cavity, effectively removing smaller particulate impurities. The fourth filter section 44, located above the third filter section 43, further filters out tiny particles, ensuring that the water entering the washing pump and drain pump reaches a high level of cleanliness. This four-stage filtration system significantly improves the interception efficiency of impurities in the washing water, protecting the pump body from wear and extending the equipment's service life, while also ensuring the cleanliness of the washing water and improving the washing effect. The first filter section 41, the second filter section 42, the third filter section 43, and the fourth filter section 44 are manufactured using an integrated molding process, effectively resisting the strong scouring of water during washing and the vibration generated by pump operation, reducing the risk of impurity leakage due to structural damage, and ensuring long-term stability of the filtration effect. Meanwhile, the robust structure prevents the filter from deforming due to external forces during installation and disassembly, ensuring precise fit with components such as the flat filter 2 and the water collector cavity 303, thus improving the stability of the entire washing structure. The placement of the annular housing 45 in the third filter section 43, abutting against the inner wall of the water collector 3, has a significant effect. During drainage, the water flow must return through the third filter hole 403, achieving secondary filtration of the drainage compared to when the annular housing 45 does not contact the water collector 3 housing. When wastewater enters the second cavity of the water collector cavity 303, under the action of the drainage pump 6, the water flow must pass through the third filter hole 403 to enter the channel connected to the drainage pump inlet 302. At this time, the third filter hole 403 can again intercept residual impurities in the wastewater, including tiny particles and fibers that may have been missed during the initial filtration process.This secondary filtration mechanism effectively improves the filtration accuracy of the entire washing structure, reduces potential sewer blockages caused by impurities discharged with wastewater, and also reduces wear on drainage pipes, extending the service life of the drainage system. Simultaneously, the annular housing 45 divides the water collector cavity 303 into a first cavity and a second cavity, optimizing the water flow path. Washing water gathers in the first cavity of the water collector cavity 303 and, through connection with the washing pump inlet 301, enters the washing pump 5 via the shortest and most direct path, reducing water flow detours and energy loss within the cavity and improving the pumping efficiency. Impurities, on the other hand, concentrate in the second cavity and, through connection with the drain pump inlet 302, are quickly discharged by the drain pump 6, preventing impurities from accumulating within the cavity and ensuring efficient and smooth drainage.
[0055] like Figures 6 to 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the planar filter 2 is provided with micropores, and the number of micropores is multiple; the outer wall of the third filter section 43 and the inner wall of the water collector 3 form a filtration water path; the multiple micropores, the water collection tank 101, the filtration water path, and the washing pump inlet 301 form a first channel; the first filter section 41 is provided with a first filter hole 401, the second filter section 42 is provided with a second filter hole 402, and the third filter section 43 is provided with a third filter hole 403; the first filter hole 401, the second filter hole 402, and the third filter hole 403... The first, second, third, and fourth channels are formed by multiple first filter holes 401, multiple second filter holes 402, multiple third filter holes 403, and the washing pump inlet 301. The fourth filter section 44 is provided with multiple fourth filter holes 404, which are also multiple. The third channel is formed by multiple first filter holes 401, multiple second filter holes 402, multiple fourth filter holes 404, and the drain pump inlet 302. The fourth channel is formed by multiple micropores, a water collection tank 101, a filtration water path, third filter holes 403, multiple fourth filter holes 404, and the drain pump inlet 302. By utilizing the planar filter 2 and the cylindrical filter 4 to construct the first, second, third, and fourth channels through micropores and filter holes, the washing structure gains efficient and precise filtration functions and water flow management advantages. The first channel utilizes multiple micropores of the planar filter 2, combined with the water collection tank 101, the filtration water path formed by the outer wall of the third filter section 43 and the inner wall of the water collector 3, and the washing pump inlet 301, to preferentially intercept larger impurities in the washing water. Larger impurities are blocked on the surface of the planar filter 2, preventing them from entering the subsequent water path and thus avoiding blockage or wear on the washing pump 5, ensuring stable operation of the washing pump 5. The second channel consists of multiple first filter holes 401, second filter holes 402, and third filter holes 403 of the cylindrical filter 4 and the washing pump inlet 301, focusing on filtering smaller particulate impurities. When water flows through, these smaller particulate impurities are intercepted layer by layer by the filter holes, resulting in higher cleanliness of the water entering the washing pump, ensuring efficient operation of the washing pump, and improving the purity of the washing water, thereby enhancing the washing effect. The third and fourth channels, with the help of multiple fourth filter holes 404 of the fourth filter section 44, cooperate with other filter holes and the drain pump inlet 302 to undertake the important task of removing tiny impurities. The aperture of the fourth filter hole 404 is precisely designed to ensure the smooth discharge of tiny impurities while effectively preventing particles that may affect the normal operation of the rotating impeller of the drain pump 6 from entering. This not only avoids the risk of the drainage pump impeller getting stuck, preventing serious malfunctions such as overload and burnout of the drainage pump motor caused by impeller jamming, but also reduces frictional losses between the impeller and impurities, effectively extending the service life of the drainage pump.
