[0032] The above solution of the present utility model has at least the following beneficial effects:
[0033] The water tank structure of the cleaning equipment provided by the present utility model includes: a main washing water tank, on which a second drain port is provided; a heat recovery water tank, on which a third drain port is provided; a water distributor, which has a first accommodating cavity, and the first accommodating cavity is adapted to communicate with an external drainage mechanism, the third drain port and the second drain port; an overflow device, which can be selectively arranged in the first accommodating cavity. Wherein, the water distributor has a closed state and an open state. When in the closed state, at least part of the overflow device is arranged in the first accommodating cavity so that the third drain port and the second drain port are not communicated with the external drainage mechanism; when in the open state, the overflow device is away from the first accommodating cavity so that the third drain port and the second drain port are communicated with the external drainage mechanism. In this application, the third drain port of the heat recovery water tank and the second drain port of the main washing water tank are communicated with the external drainage mechanism through the first accommodating cavity of the water distributor, so that the opening and closing of the first accommodating cavity can be controlled by whether the overflow device is arranged in the first accommodating cavity. Furthermore, when in the open state, the main washing water tank and the heat recovery water tank can be emptied simultaneously by pulling out the overflow device, which improves the drainage efficiency.
[0034] Furthermore, in this application, a first overflow port is opened on the side wall of the main washing water tank, and a water inlet is opened on the side wall of the heat recovery water tank, and the two are communicated through an overflow pipe. By setting the first overflow port higher than the water inlet, the liquid in the main washing water tank can directly enter the heat recovery water tank under the action of gravity, making the structure simpler.
[0035] Furthermore, in this application, it is set that the first overflow port is located at the upper end of the main washing water tank in the height direction. Since the density of impurities such as oil is lower than that of water, by setting the first overflow port above the main washing water tank, impurities such as oil floating above the water surface can also flow out from the first overflow port, avoiding the accumulation of impurities such as oil in the main washing water tank for a long time and affecting the cleaning effect of the main washing water tank.
[0036] Furthermore, in this application, a heat conduction mechanism is provided in the heat recovery water tank. The water inlet is located at the first end of the heat recovery water tank, and the first drain port is located at the second end of the heat recovery water tank. At least part of the heat conduction mechanism is arranged between the first end and the second end, and the first end is higher than the second end. In this application, after the relatively hot water flows to the upper part of the heat recovery water tank and heats the heat conduction mechanism to be heated, the cooled water is discharged from the lower part of the heat recovery water tank, avoiding the relatively hot water being directly discharged before fully contacting the heat conduction mechanism, and improving the heat exchange efficiency.
[0037] Furthermore, the water tank structure of the cleaning device of the present application further includes a drainage pump, a water level sensor, and a control mechanism that communicate with the heat recovery water tank. The drainage pump is used to discharge the liquid in the heat recovery water tank; the water level sensor is disposed in the heat recovery water tank and is used to measure the water level in the heat recovery water tank and send a control signal to the control mechanism; the control mechanism controls the start or stop of the drainage pump according to the control signal. In the present application, the water level inside the heat recovery water tank is detected by the water level sensor. When the water level in the heat recovery water tank is higher than the water level sensor, the control mechanism can start the drainage pump according to the control signal of the water level sensor to actively extract the cold waste water at the bottom and discharge it from the heat recovery water tank. Until the water level is lower than the installation height of the water level sensor, the drainage pump stops working. It can discharge the relatively cold waste water at the bottom of the heat recovery water tank and ensure the heat of the waste water with a higher water temperature in the heat recovery water tank, improving the thermal efficiency of the heat recovery water tank and further ensuring the efficiency of heat recovery;
[0038] Furthermore, the heat recovery water tank of the present application further includes a first drainage port. The water inlet of the drainage pump is connected to the first drainage port through a first drainage pipe, and the water outlet of the drainage pump is connected to the first accommodating cavity of the water distributor through a second drainage pipe. The water inlet of the heat recovery water tank is disposed at the first end of the heat recovery water tank, and the first drainage port is located at the second end of the heat recovery water tank. In the present application, through the drainage pump, in cooperation with the first drainage port, the first drainage pipe, and the second drainage pipe, the relatively cold waste water at the bottom of the heat recovery water tank is discharged into the first accommodating cavity and discharged through an external drainage mechanism. The structure is simple. The first drainage port and the water inlet are disposed at different ends, and the discharged water is relatively cold water, so that the relatively hot water will not be directly discharged, and the relatively hot water is in full contact with the heat conduction mechanism, which can improve the efficiency of heat recovery;
[0039] Furthermore, the heat recovery water tank of the present application has a water storage cavity. The water storage cavity communicates with a third drainage port. The water storage cavity also has a communication port communicating with the outside. The water distributor is sleeved on the third drainage port. The first accommodating cavity communicates with the water storage cavity through the third drainage port. When the water distributor switches from the open state to the closed state, the overflow device sequentially enters and is disposed in the first accommodating cavity through the communication port, the water storage cavity, and the third drainage port. In the present application, by providing the communication port, it is convenient for the overflow device to rise and fall inside the water storage cavity, the third drainage port, and the first accommodating cavity, so as to facilitate the conversion between the open state and the closed state of the water distributor, and the operation is simple and convenient;
[0040] Furthermore, the overflow device of the present application includes an overflow rod. A plurality of overflow holes are provided at the first end of the overflow rod, and a fourth water outlet communicating with the overflow holes is provided at the second end. When the water distributor is in the closed state, the first end is located inside the water storage cavity, and the fourth water outlet at the second end communicates with an external drainage mechanism. The present application discharges excessive wastewater inside the heat recovery water tank into the external drainage mechanism through the overflow holes and the fourth water outlet, which can control the water level inside the heat recovery water tank, facilitating the smooth passage of the wastewater inside the main washing water tank through the first overflow port, the overflow pipe, and the water inlet into the heat recovery water tank, thereby performing heat recovery;
[0041] Furthermore, a seal is provided on the overflow rod of the present application. The seal is formed into an annular structure. When the water distributor is in the closed state, the seal abuts against the wall of the first accommodation cavity to seal the third drainage port and the second drainage port. When the water distributor of the present application is in the closed state, by the seal abutting against the wall of the first accommodation cavity, the water inside the main washing water tank is prevented from being discharged into the external drainage mechanism through the second drainage port and the first accommodation cavity, and the water inside the heat recovery water tank is prevented from being discharged into the external drainage mechanism through the third drainage port and the first accommodation cavity;
[0042] Furthermore, the water tank structure of the cleaning device of the present application further includes a drainage pump. The water distributor includes a first interface, a second interface communicating with the first accommodation cavity, and a third interface communicating with the external drainage mechanism. The heat recovery water tank further includes a first drainage port. The water inlet of the drainage pump is communicated with the first drainage port through a first drainage pipe, and the water outlet of the drainage pump is communicated with the second interface through a second drainage pipe. The first interface is communicated with the second drainage port through a main washing water tank drainage pipe. Along the height direction of the first accommodation cavity, the second interface is located below the seal and above the third interface. When the water distributor of the present application is in the closed state, since the second interface is located below the seal and above the third interface, when the water level inside the heat recovery water tank is too high, the drainage pump is turned on, and the relatively cold wastewater at the bottom of the heat recovery water tank is discharged into the first accommodation cavity through the first drainage port, the first drainage pipe, the second drainage pipe, and the second interface, and the wastewater inside the first accommodation cavity is discharged through the third interface and the external drainage mechanism. By discharging the relatively cold wastewater at the bottom of the heat recovery water tank, the relatively hot water at the upper part of the heat recovery water tank can be brought into full contact with the heat conduction mechanism, which can improve the efficiency of heat recovery.

[0049] Please refer to the attached Figure 1 - Figure 2 , an embodiment of the present invention provides a water tank structure of a cleaning device, including: a main washing water tank 2, and a second drain outlet 22 is provided on the main washing water tank 2;
[0050] a heat recovery water tank 1, and a third drain outlet 13 is provided on the heat recovery water tank 1;
[0051] The water diverter 6 has a first accommodation cavity 60 which is adapted to communicate with an external drainage mechanism 7, a third drain port 13 and a second drain port 22.
[0052] The overflow device 5 can be selectively arranged in the first accommodation cavity 60.
[0053] Wherein, the water diverter 6 has a closed state and an open state.
[0054] When in the closed state, at least part of the overflow device 5 is arranged in the first accommodation cavity 60 so that the third drain port 13 and the second drain port 22 are not communicated with the external drainage mechanism 7.
[0055] When in the open state, the overflow device 5 is away from the first accommodation cavity 60 so that the third drain port 13 and the second drain port 22 are communicated with the external drainage mechanism 7.
[0056] In this embodiment, the third drain port 13 of the heat recovery water tank 1 and the second drain port 22 of the main washing water tank 2 are communicated with the external drainage mechanism 7 through the first accommodation cavity 60 of the water diverter 6, so that the opening and closing of the first accommodation cavity 60 can be controlled by whether the overflow device 5 is arranged in the first accommodation cavity 60; when the water diverter 6 is in the closed state, part of the overflow device 5 is arranged in the first accommodation cavity 60 so that the third drain port 13 and the second drain port 22 are not communicated with the external drainage mechanism 7, and the water inside the main washing water tank 2 will not be discharged from the second drain port 22, and the water inside the heat recovery water tank 1 will not be discharged from the third drain port 13; when it is necessary to empty the main washing water tank 2 and the heat recovery water tank 1, by pulling out the overflow device 5, the water diverter 6 is in the open state, so that the second drain port 22 and the third drain port 13 are communicated with the external drainage mechanism 7 through the first accommodation cavity 60, thereby realizing the simultaneous emptying of the main washing water tank 2 and the heat recovery water tank 1 and improving the drainage efficiency.
[0057] Wherein, the above-mentioned external drainage mechanism 7 can be used to discharge water to the outside of the dishwasher. For example, the above-mentioned external drainage mechanism 7 can be a drain pipe connected to the sewer, or a drainage pump for drainage, etc.
[0058] In an alternative embodiment of the present utility model, the main washing water tank 2 has a first overflow port 21, and the heat recovery water tank 1 has a water inlet 11.
[0059] The first overflow port 21 is arranged at a first position on the side wall of the main washing water tank 2.
[0060] The water inlet 11 is arranged at a second position on the side wall of the heat recovery water tank 1, and the height at the second position is less than the height at the first position. The first overflow port 21 and the water inlet 11 are communicated through an overflow pipe 3.
[0061] In this embodiment, when the cleaning equipment is operating normally, when the water level in the main washing tank 2 exceeds the height of the first overflow port 21, since the height of the first overflow port 21 is higher than that of the water inlet 11, the excess wastewater in the main washing tank 2 will naturally enter the heat recovery tank 1 through the first overflow port 21, the overflow pipe 3, and the water inlet 11, and there will be no backflow phenomenon;
[0062] The connection between the first overflow port 21 and the water inlet 11 is realized through the overflow pipe 3, which can reduce the pipeline laying, thereby reducing the manufacturing cost of the cleaning equipment and the heat loss during heat recovery;
[0063] The hot air generated after the wastewater enters the heat recovery tank 1 is concentrated in the upper part of the heat recovery tank 1, which is convenient for centralized heat collection.
[0064] In an alternative embodiment of the present invention, along the height direction X, the first overflow port 21 is located at the upper end of the main washing tank 2.
[0065] In this embodiment, by arranging the first overflow port 21 at the upper end of the main washing tank 2, impurities such as oil floating on the water surface of the main washing tank 2 with a density lower than that of water can also overflow into the heat recovery tank 1, avoiding the long-term accumulation of impurities such as oil in the main washing tank 2 and affecting the cleaning effect of the main washing tank 2.
[0066] In an alternative embodiment of the present invention, a heat conduction mechanism 14 is provided in the heat recovery tank 1,
[0067] The water inlet 11 is located at the first end of the heat recovery tank 1, the first drain port 12 is located at the second end of the heat recovery tank 1, at least part of the heat conduction mechanism 14 is arranged between the first end and the second end, and the first end is higher than the second end.
[0068] In this embodiment, with the above structure, the relatively hot water can flow to the upper part of the heat recovery tank 1, heat the heat conduction mechanism 14 that needs to be heated, and then the cooled water is discharged from the lower part of the heat recovery tank 1, avoiding the relatively hot water being directly discharged before fully contacting the heat conduction mechanism 14 and improving the heat exchange efficiency.
[0069] Specifically, the above heat conduction mechanism 14 can be a heat conduction pipe. After the clear water such as tap water entering the dishwasher from an external water source flows into the heat conduction mechanism 14 and is heated, it then enters the water storage equipment in the dishwasher, such as the rinsing tank or the main washing tank 2, to preheat the incoming water.
[0070] In an alternative embodiment of the present invention, the water tank structure of the cleaning equipment further includes a drainage pump 9, a water level sensor 10 and a control mechanism communicating with the heat recovery tank 1,
[0071] The drainage pump 9 is used to discharge the liquid in the heat recovery tank 1;
[0072] The water level sensor 10 is arranged in the heat recovery water tank 1 for measuring the water level in the heat recovery water tank 1 and sending a control signal to the control mechanism;
[0073] The control mechanism controls the start or stop of the drain pump 9 according to the control signal.
[0074] In this embodiment, the cleaning device normally performs the cleaning operation. During the cleaning process, the water injected from the outside will enter the main washing water tank 2, making the water level in the main washing water tank 2 higher than the first overflow port 21. At this time, the excessive water will enter the heat recovery water tank 1 through the overflow pipe 3, making the water level in the heat recovery water tank 1 higher than the water level sensor 10; at this time, the control mechanism can start the drain pump 9 according to the control signal of the water level sensor 10 to actively pump and discharge the cold waste water at the bottom out of the heat recovery water tank 1. Until the water level is lower than the installation height of the water level sensor 10, the drain pump 9 stops working, which can discharge the relatively cold waste water at the bottom of the heat recovery water tank 1 and ensure the heat of the relatively warm waste water in the heat recovery water tank 1, improving the heat efficiency of the heat recovery water tank 1 and further ensuring the efficiency of heat recovery.
[0075] In an alternative embodiment of the present utility model, the heat recovery water tank 1 further includes a first drain port 12. The water inlet of the drain pump 9 is communicated with the first drain port 12 through a first drain pipe 81, and the water outlet of the drain pump 9 is communicated with the first accommodation cavity 60 of the water distributor 6 through a second drain pipe 82. The water inlet 11 of the heat recovery water tank 1 is arranged at the first end of the heat recovery water tank 1, and the first drain port 12 is located at the second end of the heat recovery water tank 1.
[0076] In this embodiment, the drain pump 9 works, and the relatively cold waste water at the bottom of the heat recovery water tank 1 is discharged into the first accommodation cavity 60 through the first drain port 12, the first drain pipe 81, and the second drain pipe 82, and is discharged through the external drainage mechanism 7. The structure is simple; the first drain port 12 and the water inlet 11 are arranged at different ends, and the discharged water is relatively cold water, so that the relatively warm water will not be directly discharged, and the relatively warm water is in full contact with the heat conduction mechanism 14, which can improve the efficiency of heat recovery.

[0078] When the water distributor 6 is switched from the open state to the closed state, the overflow device 5 sequentially enters and is arranged in the first accommodation cavity 60 through the communication port, the water storage cavity, and the third drain port 13.
[0079] In this embodiment, by providing a communication port, it is convenient for the overflow device 5 to lift inside the water storage cavity, the third drain port 13, and the first accommodation cavity 60, so as to facilitate the conversion between the open state and the closed state of the water distributor 6, and the operation is simple and convenient.
[0080] In an alternative embodiment of the present utility model, the overflow device 5 includes an overflow rod 50. A plurality of overflow holes 53 are provided at the first end of the overflow rod 50, and a fourth water outlet 52 communicating with the overflow holes 53 is provided at the second end.
[0081] When the water distributor 6 is in the closed state, the first end is located inside the water storage cavity, and the fourth water outlet 52 at the second end communicates with the external drainage mechanism 7.
[0082] In this embodiment, when the water distributor 6 is in the closed state and the water level inside the heat recovery water tank 1 is higher than the plurality of overflow holes 53, the excess wastewater inside the heat recovery water tank 1 is discharged into the external drainage mechanism 7 through the overflow holes 53 and the fourth water outlet 52, which can control the water level inside the heat recovery water tank 1 and facilitate the wastewater inside the main washing water tank 2 to smoothly enter the heat recovery water tank 1 through the first overflow port 21, the overflow pipe 3, and the water inlet 11, so as to carry out heat recovery.
[0083] That is, the overflow holes 53 can achieve automatic water overflow when the drainage pump 9 and the water level sensor 10 fail and cannot drain water actively, avoiding the problem of too high water level inside the heat recovery water tank 1 when the above devices fail.
[0084] In an alternative embodiment of the present utility model, a seal 51 is provided on the overflow rod 50. The seal 51 is formed into an annular structure. When the water distributor 6 is in the closed state, the seal 51 abuts against the cavity wall of the first accommodation cavity 60 to seal the third drain port 13 and the second drain port 22.
[0085] In this embodiment, when the water distributor 6 is in the closed state, by the seal 51 abutting against the cavity wall of the first accommodation cavity 60, it is possible to prevent the water inside the main washing water tank 2 from being discharged into the external drainage mechanism 7 through the second drain port 22 and the first accommodation cavity 60, and prevent the water inside the heat recovery water tank 1 from being discharged into the external drainage mechanism 7 through the third drain port 13 and the first accommodation cavity 60.
[0086] In an alternative embodiment of the present utility model, the water tank structure of the cleaning device further includes a drainage pump 9. The water distributor 6 includes a first interface 61, a second interface 62 communicating with the first accommodation cavity 60, and a third interface 63 communicating with the external drainage mechanism 7.

[0088] In this embodiment, when the water distributor 6 is in the closed state, since the second interface 62 is located below the seal 51 and above the third interface 63, when the water level in the heat recovery water tank 1 is too high, the drainage pump 9 is turned on, and the relatively cold waste water at the bottom of the heat recovery water tank 1 is discharged into the first accommodating cavity 60 through the first drain port 12, the first drain pipe 81, the second drain pipe 82 and the second interface 62. The waste water inside the first accommodating cavity 60 is discharged through the third interface 63 and the external drainage mechanism 7. By discharging the relatively cold waste water at the bottom of the heat recovery water tank 1, the relatively hot water at the upper part of the heat recovery water tank 1 can be brought into full contact with the heat conduction mechanism 14, and the efficiency of heat recovery can be improved.
[0089] It should be known that the cleaning device described in the above embodiment can be a dishwasher, but is not limited to a dishwasher, and other cleaning devices including the above two water tank structures are also applicable.
[0090] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
