[0069] In China, municipal water supply pipes can only supply water at room temperature. Therefore, water tanks are typically used to store tap water and then heat it to mix with other tap water to create water at different temperatures. In Europe and America, water supply systems can provide both hot and cold tap water.

[0070] In view of this, this application provides a water tank and a cleaning machine that are compatible with water supply systems that directly supply room temperature water and hot water, without the need to add a heating module to the water tank.

[0071] Referring to Figures 1 to 3, the water tank 100 includes a tank body 1, which has a first water chamber 11 and a second water chamber 12 spaced apart. The tank body 1 is provided with a first inlet 111 and a first outlet 112 communicating with the first water chamber 11. The first inlet 111 is used to allow external hot water to enter the first water chamber 11, and the first outlet 112 is used to output the hot water in the first water chamber 11. The tank body 1 is provided with a second inlet 121 and a second outlet 122 communicating with the second water chamber 12. The second inlet 121 is used to allow external room temperature water to enter the second water chamber 12, and the second outlet 122 is used to output the room temperature water in the second water chamber 12. The hot water output from the first outlet 112 is used to mix with the room temperature water output from the second outlet 122.

[0072] In the technical solution of this application, hot water provided by the municipal water supply system can flow into the first water chamber 11 from the first inlet 111, and room temperature water can flow into the second water chamber 12 from the second inlet 121, so that the water tank 100 can store water of different temperatures. The hot water in the first water chamber 11 is output from the first outlet 112, and the room temperature water in the second water chamber 12 is output from the second outlet 122. The hot water and room temperature water can be mixed after being output, and can be mixed according to the usage requirements to obtain water of the required temperature. It can be seen that this application provides a new water tank 100, which can be directly adapted to the room temperature water and hot water supplied by the water supply system without the need for additional heating devices, and has strong applicability.

[0073] Specifically, the first water cavity 11 and the second water cavity 12 are integrated into a single housing 1. They can be arranged vertically, horizontally, or stacked in a front-to-back direction; this application does not impose any restrictions on this arrangement. The volumes of the first water cavity 11 and the second water cavity 12 can be the same or different.

[0074] It should be noted that the first water chamber 11 is connected to an external hot water source to store hot water flowing from the municipal water supply system. This means the external hot water source provides hot water to the municipal water supply system. Hot water typically refers to water with a temperature between 40 and 80 degrees Celsius. However, the specific temperature range may vary depending on the region, and the exact temperature of the hot water is not limited. The second water chamber 12 is connected to an external ambient temperature water source to store ambient temperature water flowing from the municipal water supply system. This means the external ambient temperature water source provides ambient temperature water to the municipal water supply system. Ambient temperature water is tap water, typically between 10 and 25 degrees Celsius. The specific temperature is affected by the season and environment; in winter, the ambient temperature water is lower, and in summer, it is higher. The exact temperature of the ambient temperature water is not limited.

[0075] Water from the first outlet 112 and the second outlet 122 can be piped to a mixing chamber for thorough mixing before being discharged. Alternatively, a three-way valve can be installed to facilitate mixing and discharge. In one embodiment of this application, the water tank 100 is further equipped with a mixing device 2, which includes a mixing chamber 21 and an adjusting structure. The mixing chamber 21 is connected to the first water chamber 11 via the first outlet 112 and to the second water chamber 12 via the second outlet 122. The adjusting structure controls the opening and / or the degree of opening of the first outlet 112 and the second outlet 122. The mixing chamber 21 is also equipped with a water outlet 1c that communicates with the outside. By using the mixing device 2, the hot water in the first water chamber 11 and the room temperature water in the second water chamber 12 are mixed according to usage requirements. The mixed water flows out from the water outlet 1c for user use.

[0076] It should be noted that the mixing device 2 can be directly integrated with the water tank 100 or it can be independent. For example, a single proportional valve can be used to directly control the water output ratio of the two water chambers, and temperature adjustment can be completed at the water output port 1c. Alternatively, two regulating valves 22 can be used to control the water output of the cold and hot water chambers respectively. The water flows out of the two chambers and is then further mixed to complete the temperature adjustment.

[0077] In some embodiments, referring to Figure 3, when the first water chamber 11 and the second water chamber 12 are arranged horizontally, a mixing chamber 21 is also spaced within the housing 1, with the mixing chamber 21 located near the lower end of the housing 1; a first outlet 112 is located on the wall separating the mixing chamber 21 and the first water chamber 11, and a second outlet 122 is located on the wall separating the mixing chamber 21 and the second water chamber 12; a water outlet 1c is located at the lower end of the housing 1. That is, in this embodiment, the first outlet 112 and the second outlet 122 are first introduced into a mixing chamber 21 for mixing and then discharged. The temperature of the mixed water can be controlled by controlling the opening and closing degree of the first outlet 112 and the second outlet 122.

[0078] This application does not limit the formation of the mixing chamber 21. It can be formed by further dividing the housing 1 to form an integral chamber, or it can be formed by adding a partition or other structure. In this embodiment, the housing 1 is provided with a vertically extending partition, which divides the inner cavity of the housing 1 into a first water chamber 11 and a second water chamber 12. The lower end of the partition is hollow to form the mixing chamber 21, and the first outlet 112 and the second outlet 122 are correspondingly formed at the lower end of the partition. Specifically, the partition serves to divide the inner cavity of the housing 1. It can be a separately added plate structure that ensures a sealed fit during installation, or it can be directly integrally formed with the housing 1. The thickness of the partition can be uniform or non-uniform, and this application does not limit this.

[0079] In one embodiment, referring to Figures 1 and 3, the separator includes a partition body 31 and a mounting part 32. The partition body 31 extends vertically, and its upper end is connected to the upper end of the inner cavity of the housing 1. The partition body 31 acts as a partition plate and can be directly configured as a plate-like structure extending vertically. The mounting part 32 connects the lower end of the partition body 31 to the lower end of the housing 1. A mixing chamber 21 is formed in the mounting part 32. The mounting part 32 has a first partition wall located between the first water chamber 11 and the mixing chamber 21, and a second partition wall located between the second water chamber 12 and the mixing chamber 21. The hollow cavity of the mounting part 32 needs to form the mixing chamber 21, so the volume of the mixing chamber 21 needs to be guaranteed. Therefore, when setting the shape of the mounting part 32, the maximum outer diameter should be larger than that of the partition body 31. Specifically, in this embodiment, the mounting part 32 is annularly arranged and has a hollow cylindrical chamber. Specifically, the first water outlet 112 is located in the first partition wall, the second water outlet 122 is located in the second partition wall, and the water output port 1c is located at the lower end of the mounting part 32 and extends through the lower end of the housing 1.

[0080] It should be understood that the first outlet 112 and the second outlet 122 should be staggered from the water output port 1c to avoid one of the outlets being directly opposite the water output port 1c and affecting the mixing effect.

[0081] To properly control the mixing of water, please refer to Figure 3. The longitudinal section of the mixing chamber 21 is circular. The adjustment structure includes a regulating valve 22 rotatably mounted in the mixing chamber 21. Two of the valve ports of the regulating valve 22 correspond to the first outlet 112 and the second outlet 122. It should be understood that the regulating valve 22 itself has corresponding valve ports, and the opening and closing of the corresponding valve ports can be controlled by energization, thereby indirectly controlling the conductivity of the first outlet 112 and the second outlet 122.

[0082] Based on the above embodiments, the first water outlet 112 and the second water outlet 122 are staggered because if the first water outlet 112 and the second water outlet 122 are directly opposite each other, it will directly cause the two water chambers to be connected when the regulating valve 22 is opened.

[0083] Considering the installation and fixation of the regulating valve 22, one side wall of the mixing chamber 21 is open. During installation, the regulating valve 22 is inserted through the open side into the annular mounting part 32. A groove or a locking protrusion can be provided to limit the position of the regulating valve 22. After installation, the different working positions of the regulating valve 22 are aligned with the water outlet 1c and the two slotted water outlets, respectively. When the regulating valve 22 is open, the water in the cold (hot) water chamber is guided through the water outlet to the flow path of the regulating valve 22 itself, and then flows out of the housing 1 from the water outlet 1c.

[0084] It should be noted that the regulating valve 22 can be a solenoid valve, controlled by a button connected to a circuit board assembly, or it can be connected to a mechanical button for manual adjustment by the user. In some embodiments, the regulating structure also includes a knob 23, which is exposed on the outside of the housing 1 and connected to the regulating valve 22. The knob 23 can be rotated by external force, thereby driving the regulating valve 22 to rotate. By rotating the knob 23 as needed, the user can simultaneously control whether water is flowing out of the water outlet 1c or not, and can also adjust the water temperature.

[0085] Referring to Figures 1 and 4, the first inlet 111 is located in the upper region of the tank 1, and the first outlet 112 is located in the lower region of the tank 1; the second inlet 121 is located in the upper region of the tank 1, and the second outlet 122 is located in the lower region of the tank 1. In this way, the tank 1 is placed vertically, with the inlets and outlets located at the top and bottom respectively, allowing the water to naturally converge towards the outlet under the influence of gravity.

[0086] In other embodiments, the water inlet may also be located in the middle of the tank 1. In this embodiment, both the first water inlet 111 and the second water inlet 121 are located on the upper wall of the tank 1.

[0087] Since the housing 1 is directly connected to the municipal water supply pipeline, in some embodiments, a one-way valve 6 is provided at the first inlet 111 and / or the second inlet 121 to prevent water in the housing 1 from flowing back into the public water supply pipeline. By providing a one-way valve 6 with a check function at the first inlet 111 and the second inlet 121, backflow is prevented.

[0088] Considering the recycling of resources, in some embodiments, the tank 1 is provided with a return water inlet 123 communicating with the second water chamber 12. The return water inlet 123 is located between the second inlet 121 and the second outlet 122, and is used to communicate with the recycled water source. That is, the recycled water source is introduced through the return water inlet 123, so that the recycled water source can enter the second water chamber 12 and mix with the room temperature water. It should be noted that a valve structure can be set at the return water inlet 123 to control the opening and closing of the return water inlet 123, or the opening and closing control of the pump body at the external recycled water source can be directly controlled. That is, the water tank 100 has a mode of directly using the room temperature water provided by the municipality, a mode of mixing the municipal room temperature water and the recycled water, and a mode of closing the second inlet 121 and using only the recycled water.

[0089] The location of the return water inlet 123 should be reasonably set so that it does not affect the water intake of the second inlet 121, but can still collect water at the second outlet 122. Specifically, please refer to Figure 4. In some embodiments, the second inlet 121 is located on the upper wall of the second water cavity 12, the distance between the center of the return water inlet 123 and the upper wall of the second water cavity 12 is h1, and the distance between the center of the return water inlet 123 and the lower wall of the second water cavity 12 is h2, where h1 / h2≤1 / 3. That is, the return water inlet 123 should be located in the area slightly above the second water cavity 12, but not at the same level as the second inlet 121.

[0090] Specifically, the recycled water source can be connected to the return water inlet 123 via a water pump and water pipe. This application does not limit the size and shape of the return water inlet 123; it can be designed reasonably according to actual needs. In this embodiment, the return water inlet 123 is square, the first inlet 111 and the second inlet 121 are both circular, and the first outlet 112 and the second outlet 122 are adapted to the curved shape of the mounting part 32 and are arranged in an arc-shaped groove.

[0091] Considering the installation of pipeline and valve structures, a snap-fit ​​structure is provided at each installation slot in this application, including the water inlet. That is, a section of pipe of a certain size is added to the through hole on the surface of the housing 1 to serve as a snap-fit ​​function, which facilitates installation and positioning.

[0092] In order to monitor the water level in the tank 1, a float assembly 5 is provided in the first water chamber 11 and / or the second water chamber 12. The float assembly 5 is used to detect the water level.

[0093] In this embodiment, a first opening is provided in the first water cavity 11, and a float assembly 5 is disposed at the first opening for detecting the water level in the first water cavity 11. Correspondingly, a second opening is provided in the second water cavity 12, and a float assembly 5 is disposed at the second opening for detecting the water level in the second water cavity 12. It should be understood that the structures of the float assemblies 5 in the first water cavity 11 and the second water cavity 12 can be the same or different, and no specific limitation is made here.

[0094] In this embodiment, the float assembly 5 includes a float 51 and a sensor 52. The float 51 has a first state in which it is horizontally arranged and a second state in which it is vertically arranged. The float 51 can be rotated by buoyancy to change from the second state to the first state. The sensor 52 is connected to the float 51 and is used to connect a signal line. The sensor 52 can emit a signal when the float 51 changes from the second state to the first state.

[0095] Of course, in other embodiments, the float 51 can also perform its monitoring or control functions by combining with other components. For example, when a touch sensor 52, a light sensor 52, a touch switch, etc. are set at a certain water level, the float structure can also be directly set to monitor the water level by the float 51 floating up and down.

[0096] In this embodiment, a circular mounting hole is formed at half the height of the side wall of the first water cavity 11. A ring of outward protrusions around the hole forms a bayonet for mounting and fixing the sensor 52. One end of the sensor 52 is a float 51, and the other end is connected to a signal line. The end of the sensor 52 with the float 51 is inserted into the first water cavity 11 through the mounting hole, while the other end remains outside the water tank 100 and is screwed into the bayonet to complete the installation. When the liquid level in the first water cavity 11 is equivalent to the position of the float 51, under the action of buoyancy, the float 51 rotates from the second suspended state to the first horizontal state. The detection circuit in the sensor 52 is triggered, and the output signal controls the hot water supply pipe to stop water from entering the hot water cavity, or controls the one-way valve 6 at the first water inlet 111 to close.

[0097] When a return water inlet 123 is provided on the second water chamber 12, two float assemblies 5 are installed inside the second water chamber 12. Both float assemblies 5 are located on the same horizontal side of the return water inlet 123, and on opposite vertical sides of the return water inlet 123. That is, the two float assemblies 5 are staggered from the return water inlet 123. Specifically, circular mounting holes are opened at approximately 1 / 3 and 2 / 3 of the height of the side wall of the second water chamber 12, with a ring of outwardly protruding retaining clips around the holes for installing and fixing sensors 52. The working principle of the sensors 52 is the same as above. The lower-positioned sensor 52 is used to control the on / off state of the water pump connected to the return water inlet 123; the height of the sensor 52 should be lower than the position of the return water inlet 123. The sensor 52, located at a high position, outputs a signal to control the normal temperature water supply pipe to stop water from entering the hot water chamber, or to control the opening and closing of the one-way valve 6 at the second water inlet 121. The height of the sensor 52 is between the second water inlet 121 and the return water inlet 123.

[0098] In one embodiment, the tank 1 has two overflow ports 13 that connect the first water chamber 11 and the second water chamber 12. Both overflow ports 13 are located in the upper region of the water tank 100. Specifically, overflow ports 13 are provided on the back of both the first water chamber 11 and the second water chamber 12. The position of each overflow port 13 is lower than the corresponding first water inlet 111 and second water inlet 121, which is used to discharge foam, scum, etc. in the water chamber, and at the same time can prevent the chamber from overflowing back into the tap water pipe after it is full.

[0099] For easy collection, the water tank 100 also includes a water receiving box with an open top. The water receiving box is fixed to the outside of the tank body 1 and is located below the two overflow ports 13. The water receiving port can be fixed to the outside of the water tank 100 or directly integrated into the tank body 1.

[0100] Considering that the overflow port 13 corresponds to the outer wall of the tank 1, the water flow may run along the outside of the tank 1 during overflow. Therefore, at least one overflow port 13 is connected to a water guide pipe 7. In this embodiment, an integrated water guide pipe 7 is provided, which can simultaneously connect two overflow ports 13. It can be fixed with screws.

[0101] In this embodiment, a water guide pipe 7 and a water receiving box are provided simultaneously. The water receiving box is located on the lower side of the water guide pipe 7. When the water in the water chamber is close to full, that is, when the liquid level or foam in the water chamber is higher than the overflow hole, the water and foam will flow into the external water receiving box through the overflow port 13 and the water guide pipe 7.

[0102] Referring to Figures 1 and 4, the water tank 100 includes at least one water guiding structure 4. The water guiding structure 4 is disposed within the first water cavity 11 and / or the second water cavity 12. The water guiding structure 4 extends vertically and is at least partially located below the first water inlet 111 or the second water inlet 121 to guide water from the upper region to the lower region of the tank body 1. The water guiding structure 4 primarily serves to guide and slow the flow, and also increases the strength of the tank body 1.

[0103] This application does not limit the specific form of the water guiding structure 4. It can be integrated with the housing 1 or installed and fixed separately. The first water cavity 11 and the second water cavity 12 can either be provided with the water guiding structure 4, or the water guiding structure 4 can be provided at the same time.

[0104] In some embodiments, the water guiding structure 4 includes a first water guiding section 41, at least a portion of which is inclined vertically. The first water guiding section 41 is located below the first water inlet 111 or the second water inlet 121. It should be understood that the first water guiding section 41 may be inclined vertically as a whole, forming an angle with the cavity wall. The first water guiding section 41 does not form a new closed space with the cavity wall of the water cavity, and the downward projection of the corresponding water inlet falls on the inclined section of the first water guiding section 41. The first water guiding section 41 contacts the three side walls of the corresponding water cavity in the circumferential direction, and the length and inclination of its inclined section are reasonably designed according to the position of the water inlet and the size of the water cavity.

[0105] It should be noted that when both the first water cavity 11 and the second water cavity 12 are provided with water guiding structures 4, the water guiding structures 4 in the two water cavities can be the same or different. When the first water inlet 111 and the second water inlet 121 are close to each other in the horizontal direction, the two water guiding structures 4 can be symmetrically arranged or only partially identical. It should be understood that since the size and shape of the two water cavities may be different, the size of the corresponding water guiding ribs, their relative position to the corresponding water inlet, and their inclination can also be different.

[0106] The first water guiding section 41 includes two interconnected water guiding ribs. One water guiding rib extends vertically, while the other water guiding rib is inclined vertically. In the first water cavity 11, the inclined water guiding rib connects to the side wall of the first water cavity 11, and the vertically extending water guiding rib extends to the side of the first water inlet 111. In the second water cavity 12, the vertically extending water guiding rib is located to the side of the second water inlet 121 and connects to the upper wall of the second water cavity 12, and the inclined water guiding rib extends to the side of the return water inlet 123.

[0107] In one embodiment, the water guiding structure 4 further includes a second water guiding section 42, which is located above the first water outlet 112 or the second water outlet 122. At least a portion of the second water guiding section 42 is inclined vertically, and at least a portion of it is located below the lower end of the first water guiding section 41. The second water guiding section 42 can receive water guided by the first water guiding section 41, thereby extending the water guiding path. The inclination directions of the second water guiding section 42 and the first water guiding section 41 can be the same or different. In this embodiment, the inclination directions of the first water guiding section 41 and the second water guiding section 42 are opposite, thus ensuring a sufficiently long water guiding path within a limited space, effectively mitigating water flow and preventing the water level in the water cavity from rising too quickly.

[0108] It should be noted that the structures of the second water guide part 42 and the first water guide part 41 can be the same or different. In this embodiment, the second water guide part 42 is a rib that is inclined as a whole, and is fixed on the two side walls opposite to the water cavity, respectively, as is the first water guide part 41.

[0109] When the float assembly 5 is installed inside the water cavity to detect water level changes, in order to prevent water flow from hitting the float assembly 5 and causing misjudgment of water level monitoring, the lower side of the first water guide part 41 and the inner wall of the first water cavity 11 or the second water cavity 12 define a protective space for the float assembly 5 to be placed. At this time, the first water guide part 41 plays a protective role, allowing the water flow to flow down the side of the float assembly 5 without directly impacting the surface of the float assembly 5.

[0110] Inside the first water cavity 11, the lower side of the first water guide 41 and the side wall of the first water cavity 11 where the sensor 52 is installed define a protective space, and the first water guide 41 extends to the side of the float assembly 5.

[0111] Inside the second water chamber 12, considering that the housing 1 is equipped with a return water inlet 123 communicating with the second water chamber 12, both the second inlet 121 and the return water inlet 123 can receive water. Therefore, the lower end of the first water guide part 41 inside the second water chamber 12 needs to extend to the horizontal side of the return water inlet 123. This allows the water flowing into the second inlet 121 to flow out from the side of the return water inlet 123. At this time, the first water guide part 41 can also separate the second inlet 121 and the return water inlet 123, preventing the water flow from impacting the two inlet positions and causing water to flow back from the return water inlet 123.

[0112] It should be understood that, in this embodiment, the water guiding path of the second water guiding part 42 in the second water cavity 12 should pass through the return water port 123, that is, the downward projection of the return water port 123 falls on the second water guiding part 42, so that the second water guiding part 42 can not only guide the water guided by the first water guiding part 41 in one step, but also guide the water flowing into the return water port 123.

[0113] Due to the presence of the return water inlet 123, two float assemblies 5 are installed within the second water cavity 12. To protect the two float assemblies 5, the water guiding structure 4 also includes a third water guiding section 43. The third water guiding section 43 extends vertically and is located on the opposite side of the return water inlet 123 in the horizontal direction. The upper part of the third water guiding section 43 is connected to the first water guiding section 41. At this time, the return water inlet 123 is positioned between the first water guiding section 41 and the third water guiding section 42. The downward projection of the return water inlet 123 falls on the second water guiding section 42. This not only allows the first water guiding section 41 and the third water guiding section 43 to form a protective space with the cavity wall of the second water cavity 12 where the sensor 52 is located, thus simultaneously preventing water flowing into the second inlet 121 and the return water inlet 123 from impacting the floats 51 and protecting the two floats 51, but also provides the guiding function of the return water inlet 123.

[0114] If the water level in tank 1 increases too rapidly and sensor 52 fails to respond in time and control the inlet valve to close, a large amount of water in tank 100 will overflow, wetting other surrounding structural electrical components and causing safety hazards. This problem can be mitigated by the design of the protective spaces in the first water chamber 11 and the second water chamber 12.

[0115] In one embodiment, when the tank 1 has two overflow ports 13 connecting the first water cavity 11 and the second water cavity 12, since the overflow ports 13 are located in the upper region of the water tank 100, in some embodiments, the water guiding structure 4 further includes a fourth water guiding part 44. The fourth water guiding part 44 extends in the vertical direction, and at least a portion of the fourth water guiding part 44 is located between the corresponding overflow port 13 and the first water inlet 111 or the second water inlet 121. In this embodiment, the first water cavity 11 and the second water cavity 12 are both provided with the fourth water guiding part 44. The two fourth water guiding parts 44 are respectively provided on both sides of the spacer body 31. The fourth water guiding part 44 can prevent the water flowing into the first water inlet 111 and the second water inlet 121 from splashing, so that some water flows out from the overflow port 13, so that even if the water splashes due to hitting other water guiding parts or the cavity wall, it can also flow down along the surface of the fourth water guiding part 44.

[0116] This application does not limit the specific form of the fourth water guiding part 44. The fourth water guiding part 44 can be a structure that extends vertically, or it can be partially inclined vertically, or it can be inclined vertically as a whole.

[0117] Furthermore, the fourth water guide section 44 defines a water guide channel that connects to the overflow port 13 and is open at its lower end. The cross-section of the water guide channel gradually decreases from top to bottom. This means the fourth water guide section 44 also guides overflow water. Water in the water cavity flows into the overflow port 13 along the water guide channel.

[0118] It should be understood that, however, the fourth water guiding section 44 can be set at an angle to form a water guiding channel with varying cross-sectional area. Alternatively, the fourth water guiding section 44 can be set with uneven thickness on the side facing the overflow port 13 to achieve a variation in the cross-sectional area of ​​the water guiding channel. In the embodiments of this application, the fourth water guiding section 44 includes a first water guiding section, a second water guiding section, and a third water guiding section arranged sequentially in the vertical direction. The second water guiding section is set at an angle in the vertical direction towards the overflow port 13. The first water guiding section and the third water guiding section connect the upper and lower ends of the second water guiding section, thus being staggered in the horizontal direction. Therefore, the distance between the first water guiding section and the spacer body 31 is greater than the distance between the third water guiding section 43 and the spacer body 31, resulting in the upper cross-sectional area of ​​the water guiding channel being greater than the lower cross-sectional area. Moreover, this structural form allows splashing water to naturally slide down the first water guiding section under the action of gravity through the second and third water guiding sections, achieving a better drainage effect.

[0119] Referring again to Figure 4, the fourth water guiding section 44 includes a main body section 441 and a guide section 442. The main body section 441 extends vertically, and its upper end is connected to the housing 1 and located between the corresponding overflow port 13 and the first water inlet 111 or the second water inlet 121. The guide section 442 is inclined vertically and located below the main body section 441. Since the guide section 442 is located below the main body section 441, water on the main body section 441 can fall to the guide section 442 and be guided. At the same time, the guide section 442 can also act as a guiding slope during overflow, at which time a water guiding channel is formed between the main body section 441 and the corresponding wall surface.

[0120] This application does not limit the structural form of the housing 1. The housing 1 can be integrally cast or assembled. Referring to Figure 1, the housing 1 includes a shell 1a and a cover 1b. One side of the shell 1a is open. The cover 1b is placed on the open side of the shell 1a. A partition is provided on either the cover 1b or the shell 1a to define a first water cavity 11 and a second water cavity 12 after the cover 1b and the shell 1a are closed. This arrangement facilitates processing. During assembly, it is necessary to ensure a tight seal between the shell 1a and the cover 1b. In terms of structural design, the water guiding structure 4 can be integrated into the shell 1a or the cover 1b. It is only necessary to ensure contact between the corresponding structures when the two are fastened together.

[0121] In this embodiment, please refer to Figures 1 and 4. The main body 31 is a partition extending in the vertical direction, and the mounting part 32 is a circular ring structure. Both are integrally formed with the shell 1a. A through hole opposite to the mounting part 32 is provided on the cover 1b for the regulating valve 22 to pass through and be installed. At the same time, an annular protrusion is provided on the cover 1b to limit and fix the regulating valve 22.

[0122] In addition, considering the installation of the water tank 100 structure, as shown in Figure 2, the exterior of the tank body 1 is provided with a protrusion 14, which, together with the outer side of the tank body 1, defines a mounting groove. The water tank 100 is attached to the corresponding frame structure or hook through the mounting groove, facilitating the assembly of the water tank 100.

[0123] Accordingly, when the water tank 100 has a split structure, a protrusion 14 is provided on the shell 1a. Specifically, the water receiving box should be located above the protrusion 14 to avoid the protrusion 14 obstructing the overflow path.

[0124] When the weather is cold, liquid left inside the tank 1 for an extended period may freeze and crack the tank 1. Therefore, when the water tank 100 is not in use, the water inside the tank 1 needs to be drained. Referring to Figure 5, in some embodiments of this application, the water tank 100 also includes a drain valve 15. The drain valve 15 is connected to the first water chamber 11 and the second water chamber 12 respectively, but not to the mixing chamber 21. It is used to drain the water in the first water chamber 11 and the second water chamber 12 to the outside. The first water chamber 11 and the second water chamber 12 are respectively provided with openings that connect to different working positions of the drain valve 15. The drain valve 15 is normally closed, and its valve port can be connected to a drain pipe. When drainage is needed, the drain valve 15 is activated to directly drain the water in the first water chamber 11 and the second water chamber 12 to the ground or indoor sewer.

[0125] It should be noted that the drain valve 15 can be directly integrated into the housing 1, or a separate pipeline can be led out to connect to the drain valve 15. In this embodiment, a drain chamber is separated in the housing 1. The drain chamber is located below the first water chamber 11 and the second water chamber 12 and is not connected to the mixing chamber 21. The drain chamber is connected to the outside through a drain pipe. The drain valve 15 is set on the drain pipe, specifically a one-way regulating valve 22.

[0126] The water tank 100 has a drainage mode. In drainage mode, the drain valve 15 opens, and water from the first water chamber 11 and the second water chamber 12 flows through the drain chamber into the drain pipe, thereby achieving discharge. This arrangement is to avoid spatial interference with the design of the mixed water outlet. Specifically, to prevent water in the drain chamber from flowing into the first water chamber 11 or the second water chamber 12, a valve body control opening can be added.

[0127] In addition, considering the integrated use of the equipment, please refer to Figure 5. The housing 1 also includes water passages 16 spaced apart. These water passages 16 are located to the side of the first water chamber 11 and / or the second water chamber 11, and are not connected to either chamber. The water passages 16 can be integrated into one side of the water tank, extending vertically above the tank, with both ends corresponding to each other in the vertical direction penetrating the housing 1. As an independent pipeline, it can be used to connect to external pipelines. The water passages 16 can also be used as a water pipe. For example, the water outlet 1c can be connected to the water passage 16 to deliver mixed water to the user. Furthermore, UV structures can be integrated within the water passages 16 to achieve a water filtration effect.

[0128] It should be understood that the water passage 16 can be made not to communicate with the internal space of the tank 1, and the two can only share part of the side wall. Alternatively, the water passage 16 can be designed to be connected to part of the side of the tank 1, and a valve structure can be set at the connection point.

[0129] When the water tank 100 is used as one of the components of a complex cleaning device, other water flow pipes may also be installed inside the device. The water passage 16 can be used as a pipe to connect with the corresponding structure. Since the water passage 16 is integrated into the tank 1, the pipe length can be saved.

[0130] Specifically, the length of the water passage 16 can be greater than that of the first water tank 100 and the second water tank 100, meaning that the tank body 1 does not have to be a conventional regular shape. Meanwhile, to facilitate fitting and prevent backflow, a one-way valve 6 or a connector can be installed at the end of the water passage 16.

[0131] In the technical solution of this application, the functions of the water tank 100 are expanded by optimizing the structural design and layout. This allows it to combine the functions of zoned water storage, water mixing and temperature regulation, and backflow prevention, while also achieving a compact structure and reducing the space it occupies.

[0132] This application also proposes a cleaning machine, which includes a water tank 100. The specific structure of the water tank 100 is as described in the above embodiments. Since this cleaning machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0133] Understandably, cleaning machines can be used as household or commercial appliances. Their uses are varied; for example, they can be used as shower machines for bathing, or as cleaning equipment for appliances and furniture. The specific application is not limited. The dotted arrows in the accompanying diagram indicate the direction of water flow.

[0134] Specifically, the cleaning machine also includes a water outlet assembly. One end of the water outlet assembly is connected to the first water outlet 112 and the second water outlet 122, and the other end is used to connect to the water user. The water outlet assembly may include water outlet components, including but not limited to: faucets, shower heads, etc. Of course, the water outlet assembly may also not include water outlet components. Users can configure suitable faucets, shower heads, etc. according to their own needs.

[0135] In one embodiment, the water outlet component is connected to the water mixing device 2, specifically to the water mixing chamber 21, for discharging the mixed water to the water-using end.

[0136] The cleaning machine also includes a circulating filter assembly 200, which has a water suction end and a connecting end. The connecting end is connected to the second water chamber 12. The circulating filter assembly 200 is used to draw in used water or other water sources through the water suction end, filter it, and then deliver it to the second water chamber 12. This allows the circulating water to flow into the second water chamber 12 and mix with the water originally stored in the second water chamber 12. Alternatively, it can flow directly to the water-using end through the water outlet assembly for user cleaning. In this way, the cleaning machine can recycle used water or water from other water sources to reduce water consumption and save water resources. The cleaning machine has a high water resource utilization rate.

[0137] Please refer to Figure 2. The connection end of the circulating filter component 200 is directly connected to the return water port 123 so that it can enter the second water chamber 12.

[0138] It should be noted that the circulating filter assembly 200 can be integrated into the water tank 100, or it can be located outside the water tank 100. The circulating filter assembly 200 has both water absorption and filtration functions. It draws in water through its suction end and filters it, ensuring that the water flowing into the second water chamber 12 is clean water. The water drawn in through the suction end can be water from the washing machine after use, such as bath water or water after cleaning equipment. Of course, the suction end can also draw in water from other sources, such as water from other equipment use or rainwater. In other words, the source of the water drawn in through the suction end of the circulating filter assembly 200 is not limited. The suction end of the circulating filter assembly 200 can be located below a water storage container, such as on the floor of an indoor bathroom, or in a separate water storage tank used to store water from washing or other water sources. This washing machine solution, by incorporating the circulating filter assembly 200, can recycle used water, reducing water waste, improving water utilization efficiency, and achieving water and energy conservation.

[0139] The above are merely embodiments of this application and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of this application under the inventive concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of this application.
