Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning machine inner tank assembly and a cleaning machine. Background Technology

[0002] In the design of the inner tank structure of a cleaning machine, the rationality of the layout of various functional components has a significant impact on the overall performance of the equipment. During use, some inner tank components may experience uneven distribution of components, leading to load-bearing imbalance, which in turn causes excessive vibration and insufficient structural stability during operation, thus affecting the service life of the equipment. Therefore, it is necessary to optimize the component layout of the inner tank components of the cleaning machine and design an inner tank component that can achieve uniform load-bearing and improve structural stability. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning machine inner tank assembly and a cleaning machine to address the load-bearing and stability issues of the layout of the cleaning machine inner tank assembly.

[0004] A washing machine inner tank assembly includes: an inner tank body with a washing chamber and a water inlet communicating with the washing chamber, the water inlet being located in the middle of the inner tank body; a water collection cup adjacent to the water inlet, the washing chamber communicating with the water collection cup; a washing pump mounted on the inner tank body and located in the middle of the inner tank body, the washing pump communicating with the water inlet, the washing pump and the water collection cup being sequentially arranged to form an installation dividing line; a drain pump mounted on the inner tank body and adjacent to the water collection cup, or the drain pump being mounted on the water collection cup; and a heating plate mounted on the inner tank body and adjacent to the water collection cup, the heating plate and the drain pump being located on opposite sides of the installation dividing line.

[0005] The aforementioned inner tank assembly of the cleaning machine places the washing pump in the middle of the inner tank body, with the heating plate and drain pump positioned on either side of the dividing line formed by the washing pump and the water collection cup, achieving even weight distribution within the inner tank body. The central location of the heavier washing pump helps maintain the overall center of gravity, reducing vibration and shifting during operation. The symmetrical and balanced structure formed by the heating plate and drain pump on both sides further optimizes weight distribution, contributing to improved overall structural stability and extending the equipment's service life. Simultaneously, the adjacent arrangement of each component with the water collection cup and water inlet shortens the connecting pipelines between components, improving liquid transfer efficiency.

[0006] In one embodiment, the water collecting cup includes a cup body, an inlet pipe, a connecting pipe, and a first drain pipe. The cup body is integrally formed on the inner liner body. The inlet pipe, the connecting pipe, and the first drain pipe are disposed on the cup body. The cup body has a flow cavity that communicates with the washing chamber. The inlet pipe, the connecting pipe, and the first drain pipe are respectively connected to the flow cavity. The washing pump is connected to the connecting pipe, and the drain pump is connected to the first drain pipe. Through the flow cavity of the cup body and the arrangement of the inlet pipe, the connecting pipe, and the first drain pipe, the water collecting cup can simultaneously achieve the functions of communicating with the washing chamber, supplying water to the washing pump, and draining water to the drain pump. This integrated design avoids the dispersed layout of multiple independent components, reduces the number of connection points and pipes, simplifies pipe connections, and reduces the risk of leakage. Simultaneously, the flow cavity, as a unified fluid collection area, makes the water flow path clearer and more orderly, which is conducive to improving the smoothness of fluid transmission and reducing energy loss caused by water flow turbulence.

[0007] In one embodiment, the water inlet pipe is arranged adjacent to the first drain pipe, with the water inlet pipe located on the side of the water cup body furthest from the drain pump. This adjacent arrangement allows for a compact layout, reducing the space occupied by the water collection cup, optimizing space utilization within the inner liner, and providing more installation space for other components. The water inlet pipe's location away from the drain pump ensures that the water inlet and drain paths are relatively independent, reducing water flow interference during the inlet and drain processes, avoiding pressure fluctuations caused by opposing water flows, improving water flow stability, and ensuring efficient inlet and drain processes.

[0008] In one embodiment, the washing pump includes a washing pump body, a first connector, and a second connector. The first connector is disposed on the washing pump body and located on the side of the washing pump body near the water collection cup. One end of the first connector is connected to the washing pump body, and the other end is connected to the water collection cup. The washing pump body, the first connector, and the water collection cup are sequentially connected. The second connector is disposed on the side of the washing pump body near the water inlet. One end of the second connector is connected to the water inlet, and the other end is connected to the washing pump body. The water inlet, the second connector, and the washing pump body are sequentially connected. The first connector and the second connector serve as structural components connecting the washing pump body to other components, and are respectively positioned near the water collection cup and the water inlet, making the connection between the washing pump body and the water collection cup and the water inlet more targeted and the structural layout more reasonable. This split connector design, compared to an integral connector structure, reduces the alignment accuracy requirements during installation and facilitates assembly. At the same time, the corresponding connection method between the connector and the washing pump body and other components enhances the tightness and stability of the connection, reduces structural shaking caused by loose connections, and improves the overall installation firmness of the washing pump.

[0009] In one embodiment, the inner tank body is provided with a first mounting groove, and the water inlet is located on the side of the first mounting groove near the washing pump. The second connector is partially located within the first mounting groove. The first mounting groove provides limitation and support for the second connector, enhancing the connection stability between the second connector and the inner tank body. During the operation of the washing pump, the vibration of the pump body is transmitted to the connector. The limiting function of the first mounting groove can prevent the second connector from loosening or shifting due to vibration, ensuring connection reliability and extending the service life of the connector. At the same time, the mounting groove makes the docking between the water inlet and the second connector more precise, reducing the risk of water leakage.

[0010] In one embodiment, the second connector includes a second connector body, a first sealing ring, and a second sealing ring. The first sealing ring is sandwiched between the second connector body and the washing pump body, and the second sealing ring is sandwiched between the second connector body and the first mounting groove. The first and second sealing rings respectively enhance the sealing between the second connector and the washing pump body and the first mounting groove. The first sealing ring prevents water from leaking from the interface between the pump body and the connector when the washing pump is working, avoiding water seepage into other areas of the inner tank body that could cause electrical malfunctions. The second sealing ring prevents water from seeping out from the gap between the connector and the mounting groove, ensuring the normal operation of the washing pump and the dryness of the inner tank assembly, thus extending the service life of the equipment.

[0011] In one embodiment, the drain pump includes a pump body and a second drain pipe, the second drain pipe being disposed on the pump body. The water collection cup, the pump body, and the second drain pipe are sequentially connected. The integrated design of the second drain pipe and the pump body forms a continuous drainage structure, reducing additional pipe connections and making the overall structure of the pump more compact. This structural design not only simplifies the assembly process between the pump and the water collection cup, reducing installation difficulty, but also reduces connection gaps, enhances the structural stability of the drainage path, reduces the risk of drainage problems due to loose components, and ensures the overall reliability of the drainage system.

[0012] In one embodiment, the washing pump is provided with a water outlet pipe, which is inserted into the water inlet. A third sealing ring is also provided between the water outlet pipe and the inner tank body. The water outlet pipe is also provided with a convex ring, which abuts against the third sealing ring, thereby sealing the third sealing ring in both the axial and radial directions. The structural design of the water outlet pipe inserting into the water inlet ensures precise alignment between the washing pump and the inner tank body; the convex ring abuts against the third sealing ring and achieves double sealing in both the axial and radial directions, enhancing the overall sealing of the connection between the two, effectively preventing water leakage from gaps in different directions, ensuring the sealing reliability of the connection between the washing pump and the inner tank body, and maintaining the stability of equipment operation.

[0013] In one embodiment, the drain pump further includes a fourth sealing ring sandwiched between the drain pump body and the first drain pipe. The fourth sealing ring, serving as a sealing structure between the drain pump body and the first drain pipe, provides a targeted sealing guarantee at the connection point. This structural design creates an effective leak-proof barrier at the junction of the drain pump and the first drain pipe, preventing water from leaking through the connection gap, avoiding corrosion and damage to the internal structure of the equipment, ensuring the reliability of drainage and the safety of the inner tank components, and reducing equipment maintenance costs.

[0014] In one embodiment, the inner liner body is further provided with a second mounting groove, which is adjacent to the water collection cup and located on the side of the water collection cup away from the drain pump. The heating plate is partially located within the second mounting groove. The second mounting groove provides dedicated installation space for the heating plate. By embedding the heating plate partially into the mounting groove, circumferential restraint is formed on the heating plate, enhancing the connection stability between the heating plate and the inner liner body. This structural design effectively prevents the heating plate from shifting or shaking due to external forces such as vibration and handling during equipment operation, ensuring that the heating plate is always in the preset working position. This helps maintain a stable relative position between the heating plate and related components, ensuring the stability and consistency of the heating process and improving the overall operational reliability of the equipment.

[0015] The second aspect of this application discloses a cleaning machine, which includes: the inner tank assembly of the cleaning machine.

[0016] The aforementioned cleaning machine, by adopting the aforementioned inner tank assembly, can achieve uniform load-bearing of the overall structure, reduce the vibration amplitude during operation, and extend the service life of the equipment; the optimized layout and connection design of each component of the inner tank assembly can improve the stability and reliability of the cleaning machine operation, and ensure the efficient realization of core functions such as washing, drainage, and heating.

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] 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.

[0035] The following description, with reference to the accompanying drawings, describes some embodiments of the cleaning machine inner tank assembly and the cleaning machine according to the present invention.

[0036] Example 1

[0037] like Figures 1 to 10 As shown, this embodiment discloses a washing machine inner tank assembly, including an inner tank body 1, an inner tank body 1 having a washing chamber 101, and an inlet 102 communicating with the washing chamber 101, the inlet 102 being located in the middle of the inner tank body 1; a water collection cup 2, the water collection cup 2 being adjacent to the inlet 102, the washing chamber 101 being connected to the water collection cup 2; a washing pump 3, the washing pump 3 being mounted on the inner tank body 1 and located in the middle of the inner tank body 1, the washing pump 3 being connected to the inlet 102, the washing pump 3 and the water collection cup 2 being sequentially arranged to form an installation dividing line; a drain pump 4, the drain pump 4 being mounted on the inner tank body 1 and adjacent to the water collection cup 2 or the drain pump 4 being mounted on the water collection cup 2; and a heating plate 5, the heating plate 5 being mounted on the inner tank body 1 and adjacent to the water collection cup 2, the heating plate 5 and the drain pump 4 being located on both sides of the installation dividing line.

[0038] The cleaning machine inner tank assembly disclosed in this application has a washing pump 3 positioned in the middle of the inner tank body 1, with the heating plate 5 and drain pump 4 placed on either side of the dividing line formed by the washing pump 3 and the water collection cup 2, achieving uniform weight distribution on the inner tank body 1. The washing pump 3, being relatively heavy, is located in the middle, keeping the overall center of gravity centered and reducing vibration shifts during operation. The symmetrical and balanced structure formed by the heating plate 5 and drain pump 4 on both sides further optimizes weight distribution, contributing to improved overall structural stability and extending the equipment's service life. Simultaneously, the adjacent arrangement of each component with the water collection cup 2, water inlet 102, etc., shortens the connecting pipelines between components, improving liquid transfer efficiency.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the water collecting cup 2 includes a cup body 21, a water inlet pipe 22, a connecting pipe 23, and a first drain pipe 24. The cup body 21 is integrally formed on the inner liner body 1. The water inlet pipe 22, the connecting pipe 23, and the first drain pipe 24 are disposed on the cup body 21. The cup body 21 has a flow cavity 201, which is connected to the washing chamber 101. The water inlet pipe 22, the connecting pipe 23, and the first drain pipe 24 are respectively connected to the flow cavity 201. The washing pump 3 is connected to the connecting pipe 23, and the drain pump 4 is connected to the first drain pipe 24. Through the flow cavity 201 of the cup body 21 and the arrangement of the water inlet pipe 22, the connecting pipe 23, and the first drain pipe 24, the water collecting cup 2 can simultaneously realize the functions of communicating with the washing chamber 101, supplying water to the washing pump 3, and draining water to the drain pump 4. This integrated design avoids the scattered layout of multiple independent components, reduces the number of connection points and pipes, simplifies pipe connections, and reduces the risk of leakage. At the same time, the flow chamber 201, as a unified fluid collection area, makes the water flow path clearer and more orderly, which helps to improve the smoothness of fluid transmission and reduce energy loss caused by water flow turbulence.

[0040] In addition to the features of the above embodiments, this embodiment further specifies that: the water inlet pipe 22 and the first drain pipe 24 are arranged adjacent to each other, with the water inlet pipe 22 located on the side of the water cup body 21 away from the drain pump 4. The adjacent arrangement of the water inlet pipe 22 and the first drain pipe 24 allows for a compact layout, reducing the space occupied by the water collection cup 2, optimizing the space utilization within the inner liner body 1, and providing more installation space for other components. The location of the water inlet pipe 22 away from the drain pump 4 makes the water inlet and drain paths relatively independent, reducing water flow interference during the water inlet and drain processes, avoiding pressure fluctuations caused by water flow collisions, improving water flow stability, and ensuring efficient water inlet and drain processes.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines that: the washing pump 3 includes a washing pump body 31, a first connector 32, and a second connector 33. The first connector 32 is disposed on the washing pump body 31 and located on the side of the washing pump body 31 near the water collection cup 2. One end of the first connector 32 is connected to the washing pump body 31, and the other end of the first connector 32 is connected to the water collection cup 2. The washing pump body 31, the first connector 32, and the water collection cup 2 are connected in sequence. The second connector 33 is disposed on the side of the washing pump body 31 near the water inlet 102. One end of the second connector 33 is connected to the water inlet 102, and the other end of the second connector 33 is connected to the washing pump body 31. The water inlet 102, the second connector 33, and the washing pump body 31 are connected in sequence. The first connector 32 and the second connector 33 serve as structural components connecting the washing pump body 31 to other parts. They are respectively positioned near the water collection cup 2 and the water inlet 102, making the connection between the washing pump body 31 and the water collection cup 2 and the water inlet 102 more targeted and the structural layout more reasonable. This split connector design, compared to the integral connection structure, reduces the alignment accuracy requirements during installation and facilitates assembly operations. At the same time, the corresponding connection method between the connectors and the washing pump body 31 and other parts enhances the tightness and stability of the connection, reduces structural shaking caused by loose connections, and improves the overall installation firmness of the washing pump 3.

[0042] In addition to the features of the above embodiments, this embodiment further specifies that: the inner tank body 1 is provided with a first mounting groove 103, and the first mounting groove 103 is provided with a water inlet 102 on the side near the washing pump 3. The second connector 33 is partially located within the first mounting groove 103. The first mounting groove 103 limits and supports the second connector 33, enhancing the connection stability between the second connector 33 and the inner tank body 1. During the operation of the washing pump 3, the vibration of the pump body is transmitted to the connector. The limiting function of the first mounting groove 103 can prevent the second connector 33 from loosening or shifting due to vibration, ensuring connection reliability and extending the service life of the connector; at the same time, the setting of the mounting groove makes the docking of the water inlet 102 and the second connector 33 more precise, reducing the risk of water leakage.

[0043] In addition to the features of the above embodiments, this embodiment further specifies that: the second connector 33 includes a second connector body 331, a first sealing ring 332, and a second sealing ring 333. The first sealing ring 332 is sandwiched between the second connector body 331 and the washing pump body 31, and the second sealing ring 333 is sandwiched between the second connector body 331 and the first mounting groove 103. The first sealing ring 332 and the second sealing ring 333 respectively enhance the sealing between the second connector 33 and the washing pump body 31 and the first mounting groove 103. The first sealing ring 332 prevents water from leaking from the interface between the pump body and the connector when the washing pump 3 is working, avoiding water seepage into other areas of the inner tank body 1 and causing electrical failure; the second sealing ring 333 prevents water from seeping out from the gap between the connector and the mounting groove, ensuring the normal operation of the washing pump 3 and the dryness of the inner tank assembly, and extending the service life of the equipment.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the drain pump 4 includes a drain pump body 41 and a second drain pipe 42, the second drain pipe 42 is disposed on the drain pump body 41, and the water collection cup 2, the drain pump body 41 and the second drain pipe 42 are sequentially connected. The integrated arrangement of the second drain pipe 42 and the drain pump body 41 forms a continuous drainage structure, reduces additional pipe connection links, and makes the overall structure of the drain pump 4 more compact. This structural design not only simplifies the assembly process between the drain pump 4 and the water collection cup 2 and reduces the installation difficulty, but also reduces the connection gap, enhances the structural stability of the drainage path, reduces the risk of drainage obstruction due to loose components, and ensures the overall reliability of the drainage system.

[0045] In addition to the features of the above embodiments, this embodiment further specifies that the drain pump 4 also includes a fourth sealing ring 43, which is sandwiched between the drain pump body 41 and the first drain pipe 24. The fourth sealing ring 43 serves as a sealing structure between the drain pump body 41 and the first drain pipe 24, forming a targeted sealing guarantee through its placement at the connection point. This structural design can construct an effective leak-proof barrier at the joint between the drain pump 4 and the first drain pipe 24, preventing water from leaking through the connection gap, avoiding corrosion and damage to the internal structure of the equipment, ensuring the reliability of drainage and the safety of the inner tank components, and reducing equipment maintenance costs.

[0046] like Figure 1 , Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner liner body 1 is also provided with a second mounting groove 104, the second mounting groove 104 is adjacent to the water collection cup 2 and located on the side of the water collection cup 2 away from the drain pump 4, and the heating plate 5 is partially located in the second mounting groove 104. The setting of the second mounting groove 104 provides a dedicated installation space for the heating plate 5. By embedding the heating plate 5 partially into the mounting groove, a circumferential limit is formed on the heating plate 5, enhancing the connection stability between the heating plate 5 and the inner liner body 1. This structural design can effectively prevent the heating plate 5 from being displaced or shaking due to external forces such as vibration and handling during equipment operation, ensuring that the heating plate 5 is always in the preset working position. This is conducive to maintaining a stable relative positional relationship between the heating plate 5 and related components, ensuring the stability and consistency of the heating process, and improving the overall operational reliability of the equipment.

[0047] Example 2

The convex ring 341 abuts against the third sealing ring 35, so that the third sealing ring 341 seals in both the axial and radial directions. The structural design of the water outlet pipe 34 being inserted into the water inlet 102 ensures the precise alignment of the connection between the washing pump 3 and the inner tank body 1; the convex ring 341 abuts against the third sealing ring 35 and achieves its axial and radial double seal, enhancing the overall sealing of the connection between the two, effectively preventing water leakage from gaps in different directions, ensuring the sealing reliability of the connection between the washing pump 3 and the inner tank body 1, and maintaining the stability of equipment operation.
