Technical Field

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

[0002] Existing thermostatic valves rely solely on the tightening force of the compressed sealing ring for limiting the water temperature during installation. However, if the user applies excessive torque when adjusting the water temperature (by rotating the end of the thermostatic valve), the entire thermostatic valve will rotate, leading to inaccurate water temperature adjustment. Utility Model Content

[0003] The main purpose of this invention is to provide a cleaning machine that avoids the valve from deflecting when the user adjusts the water temperature knob excessively.

[0004] To achieve the above objectives, the cleaning machine proposed in this utility model includes:

[0005] A water storage container, including a container body and a mounting part disposed on the container body;

[0006] A mixing valve, comprising a valve core and a valve body, the valve body being disposed at the mounting portion, and the valve core being rotatably disposed on the valve body; and

[0007] A valve fixing component secures the valve body to the mounting portion to restrict the valve body from circumferentially rotating relative to the water storage container.

[0008] In one embodiment, the mounting portion protrudes from the container body, the mounting portion has a through mounting channel, and the valve body is inserted into the mounting channel.

[0009] In one embodiment, the outer periphery of the valve body is provided with a raised edge, and the inner wall of the mounting channel is provided with a stepped surface, the raised edge abutting against the stepped surface.

[0010] In one embodiment, the valve fixing member includes a ring portion and a limiting portion. The ring portion is at least partially surrounding the outer periphery of the mounting portion, and the limiting portion is disposed on the ring portion. The limiting portion is inserted into the mounting channel and engages with the valve body for limiting.

[0011] In one embodiment, the valve fixing member further includes a snap-fit ​​portion, which is disposed on the ring body portion, and the mounting portion is provided with a snap-fit ​​mating portion, wherein the snap-fit ​​portion and the snap-fit ​​mating portion snap-fit ​​into each other.

[0012] In one embodiment, one of the snap-fit ​​portion and the snap-fit ​​mating portion is configured as a snap-fit ​​protrusion, and the other is configured as a snap-fit ​​groove, wherein the snap-fit ​​protrusion and the snap-fit ​​groove engage in snap-fit ​​mating;

[0013] And / or, the ring portion is configured as a non-closed ring with an opening, and the two ends of the ring portion are respectively provided with the snap-fit ​​portion, and the limiting portion is provided between the two snap-fit ​​portions.

[0014] In one embodiment, the mounting portion has a slot extending through the mounting channel on its outer periphery, the valve body has a groove opposite to the slot, and the limiting portion extends radially along the annular portion, passing through the slot and engaging with the groove.

[0015] In one embodiment, the outer periphery of the mounting portion is provided with a limiting rib, and the side of the annular portion away from the container body abuts against the limiting rib.

[0016] In one embodiment, the container body has a first water cavity and a second water cavity, the first water cavity being connected to an external hot water source, the second water cavity being connected to an external ambient temperature water source, and the mixing valve being connected to the first water cavity and the second water cavity respectively.

[0018] The technical solution of this utility model is to install the valve body of the mixing valve onto the installation part by setting a valve fixing component, thereby assembling the mixing valve on the water storage container. The valve fixing component fixes the valve body of the mixing valve to the installation part, thereby restricting the circumferential rotation of the valve body relative to the water storage container. When the valve core is rotated in the valve body to adjust the outlet water temperature of the water storage container, it can prevent the valve core from being subjected to excessive torsional force that would cause the valve body to rotate, resulting in the entire mixing valve rotating circumferentially and causing inaccurate water temperature adjustment.

[0034] Existing thermostatic valves rely solely on the tightening force of the compressed sealing ring for limiting the water temperature during installation. However, if the user applies excessive torque when adjusting the water temperature (by rotating the end of the thermostatic valve), the entire thermostatic valve will rotate, leading to inaccurate water temperature adjustment.

[0035] This utility model proposes a cleaning machine. The aim is to improve the installation of the thermostatic valve in the cleaning machine, preventing the entire thermostatic valve from deflecting when the user excessively adjusts the water temperature knob.

[0036] Please see Figures 1 to 7 In one embodiment of the present invention, the cleaning machine 100 includes a water storage container 10, a mixing valve 20, and a valve fixing member 30; the water storage container 10 includes a container body and a mounting part 11 disposed on the container body, the mixing valve 20 includes a valve core 22 and a valve body 21, the valve body 21 is disposed on the mounting part 11, the valve core 22 is rotatably disposed on the valve body 21, and the valve fixing member 30 fixes the valve body 21 to the mounting part 11 to restrict the valve body 21 from circumferentially rotating relative to the water storage container.

[0037] The water storage container 10 can be configured as a water tank, which serves as the water storage device for the cleaning machine 100. The water tank may contain a first water chamber and a second water chamber, with a mixing valve 20 connected to both. The first water chamber can be connected to an external hot water source to store hot water supplied by the municipal water supply system. The hot water can be between 40 and 80 degrees Celsius, although the specific temperature range may vary depending on the region. The second water chamber can be connected to an external ambient temperature water source to store ambient temperature water supplied by the municipal water supply system. Ambient temperature water is the tap water supplied by the municipal system, typically between 10 and 25 degrees Celsius. The specific temperature is affected by season and environment; in winter, the ambient temperature is usually lower, and in summer, it is usually higher.

[0038] It is understandable that the cleaning machine 100 can be used as a household appliance or as a commercial appliance. The cleaning machine 100 can have a variety of uses, such as as a shower machine for users to take a bath; it can also be used as a cleaning device for furniture and household items, such as cleaning electrical appliances and furniture products. The specific use is not limited.

[0039] In this invention, rotating the valve core 22 within the valve body 21 allows for adjustment of the outlet water temperature of the mixing valve 20. For example, rotating the valve core 22 clockwise increases the outlet water temperature of the mixing valve 20, while rotating it counterclockwise decreases the outlet water temperature. Alternatively, rotating the valve core 22 clockwise decreases the outlet water temperature of the mixing valve 20, and rotating it counterclockwise increases the outlet water temperature of the mixing valve 20. The direction of rotation is not specifically limited.

[0040] When the mixing valve 20 is installed on the water storage container 10, an installation channel 111 can be provided on the water storage container 10 for inserting and installing the mixing valve 20. As for the valve fixing part 30, it can be fixed to the mounting part 11 by means of snap-fit, riveting, or plugging. When the valve fixing part 30 is fixed to the mounting part 11, the valve fixing part 30 can form a limiting engagement with the valve body 21. When the valve core 22 of the mixing valve 20 rotates in the valve body 21 to adjust the outlet water temperature, the limiting engagement between the valve fixing part 30 and the valve body 21 can restrict the circumferential rotation of the valve body 21. Even if the rotation angle of the valve core 22 is too large, when a circumferential rotational force is applied to the valve body 21, it will not cause the valve body 21 to rotate circumferentially, thus preventing the valve body 21 from shifting.

[0041] Regarding the method by which the valve fixing member 30 fixes the valve body 21 to the mounting part 11, one part of the valve fixing member 30 can be fixedly connected to the mounting part 11 or the container body, and the other part of the valve fixing member 30 can be connected to the valve body 21 of the mixing valve 20 in a limiting fit. For example, an insertion hole is opened on the outer surface of the valve body 21, and an insertion rod is provided on the valve fixing member 30. When the valve fixing member 30 is connected and fixed to the water storage container 10, the insertion rod is inserted into the insertion hole of the valve body 21 to achieve a limiting fit connection with the valve body 21 of the mixing valve 20, thereby fixing the valve body 21 to the mounting part 11 and restricting the valve body 21 from rotating circumferentially relative to the water storage container 10.

[0042] The technical solution of this utility model is to install the valve body 21 of the mixing valve 20 onto the installation part 11 by setting a valve fixing component 30, thereby assembling the mixing valve 20 onto the water storage container 10. The valve fixing component 30 fixes the valve body 21 of the mixing valve 20 to the installation part 11, thereby restricting the circumferential rotation of the valve body 21 relative to the water storage container 10. When the valve core 22 is rotated inside the valve body 21 to adjust the outlet water temperature of the water storage container 10, it can prevent the excessive torsional force on the valve core 22 from causing the valve body 21 to rotate, which would cause the mixing valve 20 to rotate circumferentially and result in inaccurate water temperature adjustment.

[0043] See Figure 2 , Figure 4 As shown, in one embodiment, the mounting part 11 protrudes from the container body, the mounting part 11 is provided with a mounting channel 111, and the valve body 21 is inserted and installed in the mounting channel 111.

[0044] In the above embodiment, the mounting part 11 can be a boss provided on the outer surface of the water storage container 10, and the mounting channel 111 is provided through the boss and connects the first water cavity and the second water cavity of the container body respectively. When the mixing valve 20 is inserted into the mounting channel 111, the connection is achieved by the insertion and cooperation of the valve body 21 of the mixing valve 20 with the mounting channel 111. A sealing ring structure can be provided on the outer periphery of the valve body 21. When the valve body 21 is inserted and installed in the mounting channel 111, the sealing ring structure is provided between the valve body 21 and the mounting channel 111, which can limit the deflection of the valve body 21 relative to the mounting channel 111. After the mixing valve 20 is installed, the valve fixing member 30 can be connected and fixed with the mounting part 11. The valve fixing member 30 and the mixing valve 20 can be connected and cooperated by the insertion rod provided in the valve fixing member 30 and the insertion hole provided in the valve body 21, which limits the deflection of the valve body 21. Therefore, when the mixing valve 20 and the valve fixing part 30 are assembled onto the water storage container 10, the function of limiting the deflection of the valve body 21 of the mixing valve 20 can be achieved.

[0045] In other embodiments, the mixing valve 20 can also be located outside the water storage container 10. The specific installation location is not limited, as long as the mixing valve 20 can communicate with both the first and second water chambers. The mixing valve 20 can be a mechanical thermostatic valve or an electronic thermostatic valve; the specific configuration can be determined as needed and is not limited here. By setting the mixing valve 20, the hot water in the first water chamber and the room-temperature water in the second water chamber can be mixed according to usage requirements to meet the user's water temperature needs.

[0046] The water storage container 10 includes a container body and a partition 12 disposed inside the container body. The partition 12 divides the inner cavity of the container body into a first water cavity and a second water cavity. The mixing valve 20 is disposed near the lower end of the partition 12.

[0047] Regarding the arrangement of the partition 12 within the container body, it can be arranged to extend from top to bottom, with the upper end of the partition 12 connected to the upper end of the inner cavity of the container body, and the lower end of the partition 12 spaced apart from the lower end of the inner cavity of the container body. The mounting part 11 can be extended into the inner cavity of the container body and connected to the lower end of the partition 12 and the lower end of the inner cavity of the container body. The mounting channel 111 of the mounting part 11 extends into the inner cavity of the container body. When the mixing valve 20 is inserted into the mounting channel 111, the mixing valve 20 is located between the lower end of the partition 12 and the bottom wall of the inner cavity of the container body.

[0048] When the mixing valve 20 is inserted into the installation channel 111, a mating structure can be provided between the valve body 21 and the installation channel 111 to prevent over-insertion of the valve body 21. (See reference...) Figure 2 As shown, in one embodiment, the outer periphery of the valve body 21 is provided with a raised edge 211, and the inner wall of the mounting channel 111 is provided with a stepped surface 111a, with the raised edge 211 abutting against the stepped surface 111a. This arrangement prevents the valve body 21 of the mixing valve 20 from being over-inserted, and avoids the valve fixing member 30 failing to accurately find the correct position to mate with the valve body 21 when subsequently used to fix the mixing valve 20.

[0049] The structure of valve fixing component 30 will be further described below. (See reference...) Figure 4 , Figure 5 As shown, optionally, the valve fixing member 30 includes an annular portion 31 and a limiting portion 33. The annular portion 31 at least partially surrounds the outer periphery of the mounting portion 11, and the limiting portion 33 is disposed on the annular portion 31. The limiting portion 33 is inserted into the mounting channel 111 and engages with the valve body 21 for limiting. The valve fixing member 30 also includes a snap-fit ​​portion 32, which is disposed on the annular portion 31. The mounting portion 11 is provided with a snap-fit ​​engagement portion 112, and the snap-fit ​​portion 32 engages with the snap-fit ​​engagement portion 112.

[0050] In the above embodiment, the annular portion 31 of the valve fixing member 30 can be configured as a retaining ring. When the mounting portion 11 is configured as a boss, the retaining ring can be engaged with the outer periphery of the boss. At the same time, the engaging portion 32 can be configured as a retaining protrusion, and the engaging mating portion 112 located on the mounting portion 11 can be configured as a retaining groove. When the retaining ring is engaged with the outer periphery of the boss, the retaining protrusion can be engaged into the retaining groove, so that the valve fixing member 30 and the mounting portion 11 are connected and fixed. Furthermore, since the annular portion 31 is provided with the engaging mating portion 112, the engaging mating portion 112 can be configured as a plug protruding towards the mounting portion 11. When the valve fixing member 30 is connected and fixed to the mounting portion 11, the plug can be inserted into the mounting channel 111 and connected with the valve body 21, thereby realizing the circumferential deflection of the valve body 21. Alternatively, the snap-fit ​​part 32 can be configured as a snap-fit ​​groove, and the snap-fit ​​mating part 112 can be configured as a snap-fit ​​protrusion, which can also achieve the connection and fixation between the valve fixing part 30 and the mounting part 11.

[0051] Optionally, one of the snap-fit ​​portion 32 and the snap-fit ​​mating portion 112 is configured as a snap-fit ​​protrusion and the other is configured as a snap-fit ​​groove, wherein the snap-fit ​​protrusion and the snap-fit ​​groove engage in snap-fit ​​mating.

[0052] Alternatively, in other embodiments, both the snap-fit ​​portion 32 and the snap-fit ​​mating portion 112 are configured as snap-fit ​​grooves. When the ring portion 31 is arranged around the outer periphery of the mounting portion 11, the two snap-fit ​​grooves are connected and interlocked. Inserting a plug structure between the two snap-fit ​​grooves can also achieve the engagement of the snap-fit ​​portion 32 and the snap-fit ​​mating portion 112. No specific limitation is made here.

[0053] When the latching part 32 is configured as a latching protrusion, at least two latching protrusions may be provided. See reference. Figure 5 As shown, optionally, the ring portion 31 is arranged in a non-closed ring shape with an opening, and the two ends of the ring portion 31 are respectively provided with the snap-fit ​​portion 32, and the limiting portion 33 is provided between the two snap-fit ​​portions 32.

[0054] With this configuration, when the valve fixing member 30 is installed onto the mounting part 11 via the engagement of the snap-fit ​​part 32 and the snap-fit ​​mating part 112, both ends of the ring part 31 can connect with the mounting part 11, preventing it from being exposed relative to the mounting part 11 and resulting in an unsightly appearance after installation. Furthermore, since both ends of the ring part 31 can be connected to the mounting part 11 via the snap-fit ​​part 32 and the snap-fit ​​mating part 112, when the limiting part 33 is positioned between the two snap-fit ​​parts 32, the connection between the two snap-fit ​​parts 32 and the mounting part 11 increases the stability of the limiting engagement between the limiting part 33 and the valve body 21.

[0055] The following section provides a further explanation of how the limiting part 33 cooperates with the valve body 21. (See reference...) Figure 3 , Figure 5 , Figure 7As shown, the mounting part 11 has a slot 113 extending through the mounting channel 111 on its outer periphery, the valve body 21 has a groove 212 opposite to the slot 113, and the limiting part 33 extends radially along the annular part 31, the limiting part 33 passes through the slot 113 and is inserted into the groove 212.

[0056] The limiting part 33 can be configured as a plug rod. The size of the slot 113 in the mounting part 11 can be larger than the cross-sectional size of the plug rod, as long as the plug rod can be inserted into the mounting channel 111. No specific limitation is made here. When the groove 212 is provided, the inner walls on the left and right sides of the groove 212 can at least abut against the plug rod, so that when the valve body 21 deflects, the deflection of the valve body 21 relative to the plug rod can be limited. Alternatively, the inner walls on the upper and lower sides of the groove 212 can be additionally provided to abut against the plug rod, thereby limiting the vertical displacement of the valve body 21 relative to the plug rod, thereby limiting the movement of the valve body 21.

[0057] To improve the fixing effect of the valve fixing member 30 on the mounting part 11 and to improve the limiting effect of the valve fixing member 30 on the valve body 21, this utility model can also provide a limiting rib 114 on the outer periphery of the mounting part 11, which cooperates with the annular part 31 of the valve fixing member 30. (See reference) Figure 5 , Figure 7 As shown, in one embodiment, the mounting portion 11 is provided with a limiting rib 114 on its outer periphery, and the side of the ring portion 31 away from the container body abuts against the limiting rib 114.

[0058] In the above embodiment, two limiting ribs 114 can be provided, spaced apart. The limiting part 33 provided on the ring part 31 can be provided close to the side of the ring part 31 away from the container body. When the limiting part 33 is inserted from the slot 113 into the groove 212, the side of the ring part 31 away from the container body abuts against the limiting rib 114. This arrangement allows the valve fixing member 30 to limit the movement of the valve body 21 toward the side away from the container body, enabling the valve fixing member 30 to axially limit the valve body 21.

[0059] See Figure 2 , Figure 3 As shown, in one embodiment, a sealing ring is provided around the valve body 21, which is used to restrict the valve body 21 from rotating circumferentially relative to the mounting channel 111.

[0060] The valve body 21 can be equipped with multiple sealing rings, which are spaced apart axially along the valve body 21. For example, the sealing rings can be a first sealing ring 213, a second sealing ring 214, and a third sealing ring 215 spaced apart axially. When the valve body 21 is inserted into the installation channel 111, the first sealing ring 213, the second sealing ring 214, and the third sealing ring 215 abut against the inner wall of the installation channel 111, thereby limiting the circumferential rotation of the valve body 21 relative to the installation channel 111. Furthermore, when the mixing valve 20 discharges water, the portion of the valve body 21 located between the first sealing ring 213 and the second sealing ring 214 communicates with the first water chamber, and the portion of the valve body 21 located between the second sealing ring 214 and the third sealing ring 215 communicates with the second water chamber, thereby enabling the mixing valve 20 to discharge water through the first water chamber and / or the second water chamber.

[0061] In another embodiment, the water storage container 10 can also be configured as a first water tank and a second water tank, which can be separate structures; or, the first water tank and the second water tank can be an integrated structure. When the first water tank and the second water tank are separate structures, it is convenient to manufacture and install them separately, and it is also convenient to maintain or clean either one. When the first water tank and the second water tank are an integrated structure, the water storage container has a compact structure, the integrated design reduces material usage and installation costs, and the structure is more robust.

[0062] The cleaning machine 100 of this utility model also includes a water outlet component. Further, the water outlet component is connected to the mixing valve 20 to discharge the mixed water to the user end. The water outlet component may include, but is not limited to, a water outlet element such as a faucet or shower head; of course, the water outlet component may also not include a water outlet element, and users can configure suitable faucets, shower heads, etc., according to their own needs.

[0063] Optionally, the water outlet assembly includes a first pipeline and a first pump body. One end of the first pipeline is connected to the mixing valve 20, and the other end of the first pipeline is connected to the water-using end. The first pump body is disposed on the first pipeline. It is understood that by providing the first pump body, the water mixed by the mixing valve 20 can be pumped along the first pipeline to the water-using end, providing a strong water flow and improving the cleaning capacity of the cleaning machine. Furthermore, a water outlet fitting can be installed at the outlet end of the first pipeline for user convenience.

[0064] In one embodiment, the cleaning machine 100 further includes a drainage component connected to the first pipeline. The cleaning machine 100 is used to discharge the remaining water after washing through the drainage component. It is understood that after the cleaning machine 100 finishes washing, water remains in the first and second water chambers of the water storage container, and water also remains in the first pipeline of the water outlet component. If the cleaning machine 100 is not used for a long time, the water remaining in the water chambers and pipelines is prone to bacterial growth and corrosion of the container and pipelines, affecting the service life of the cleaning machine 100. Therefore, the cleaning machine 100 in this solution is equipped with a drainage component connected to the first pipeline. The remaining water in the first and / or second water chambers after washing can flow into the first pipeline, and the remaining water in the first pipeline can flow through the discharge component and be discharged outwards, thereby realizing the function of the cleaning machine 100 in discharging the remaining water after washing and improving the reliability and service life of the cleaning machine 100.
