[0033] The existing water supply and drainage device of the clothes care machine pointed out in the background art cannot simultaneously consider the purification effect and water supply speed in the process of recycling wastewater, resulting in the problem of low efficiency of wastewater recycling. The present application provides a water supply and drainage device of a clothes care machine and a clothes care machine, which sets a filter box and a filter assembly between the wastewater box and the water supply box, separates the inner cavity of the filter box into a sewage cavity communicated with the wastewater box and a clean water cavity communicated with the water supply box through the filter assembly, and installs a water-air dual-purpose pump at the communication between the clean water cavity and the water supply box. By extracting the air in the clean water cavity to form a negative pressure, the effect of accelerating wastewater purification is achieved.

[0034] Specifically, as shown in Figure 1 The present application provides a water supply and drainage device of a clothes care machine, which comprises: a wastewater box 1 capable of collecting and storing wastewater after clothes care; a water supply box 2, the water outlet end of which is communicated with the water supply device of the clothes care machine, and which is capable of delivering water source to the water supply device; a filter box, which comprises a clean water cavity 33, the water inlet end of which is directly or indirectly communicated with the water outlet end of the wastewater box 1, and the water outlet end of which is communicated with the water inlet end of the water supply box 2; a filter assembly 32, which is arranged at the water inlet end of the clean water cavity 33 and is capable of filtering and purifying wastewater; and a water-air dual-purpose pump 4, which is installed at the water outlet end of the clean water cavity 33 and is capable of pumping clean water in the clean water cavity 33 into the water supply box 2, and extracting air in the clean water cavity 33 to form a negative pressure, accelerating the penetration of wastewater into the clean water cavity 33.

[0035] Exemplarily, the clothes care machine comprises a care chamber and a circulating air duct, the air inlet and the air outlet of the circulating air duct are communicated with the care chamber, and the heating device, the dehumidifying device and the fan are installed in the circulating air duct.

[0036] When the clothes drying equipment executes the drying mode, the air in the circulating air duct is first heated to a certain temperature by the heating device, then enters the care chamber from the air outlet under the action of the fan to form a high-temperature airflow, the high-temperature airflow fully contacts with the wet clothes in the care chamber, the clothes are high-temperature baked, the water in the clothes evaporates into water vapor, and the humid air containing the water vapor flows back to the circulating air duct again under the action of the fan, in the circulating air duct, the low-temperature humid air is heated and dehumidified by the heating device and the dehumidifying device again, and then becomes high-temperature dry air which is sent into the care chamber to be continuously circulated.

[0037] The dehumidifying device is a condenser, which can liquefy the water vapor in the air at low temperature to generate condensation on the condenser, so as to separate the water from the air to achieve the purpose of dehumidification.

[0038] The wastewater box 1 in the utility model can collect and store the water droplets on the condenser, when the collection amount of the wastewater reaches the preset amount, the wastewater will be introduced into the filter box for filtration and purification, so that the wastewater becomes clean water which is then introduced into the water supply box 2, the water supply box 2 is communicated with the care devices such as the humidifying device through the pipeline to supplement the clean water required for humidification, so that the recycling of the wastewater is realized, the user does not need to frequently empty the wastewater box 1, the injection amount of the external water source is reduced, and water is saved.

[0039] In order to improve the purification capacity, the filter assembly 32 is preferably a reverse osmosis membrane, under normal circumstances, the water flow through the reverse osmosis membrane is slow, which leads to slow purification speed of the wastewater, thereby affecting the utilization efficiency of the wastewater.

[0040] The water-air dual-purpose pump 4 in the utility model can not only quickly introduce the clean water in the clean water cavity 33 into the water supply box 2, but also can suck the air in the clean water cavity 33 to reduce the air pressure in the clean water cavity 33, so that the negative pressure is formed in the clean water cavity 33, the wastewater is pressed into the clean water cavity 33, the penetration speed of the wastewater to the clean water cavity 33 is improved, the purification speed of the wastewater is improved while ensuring the purification effect of the wastewater, and the recycling efficiency of the wastewater is improved.

[0042] Specifically, during the purification process, the waste water can be first introduced into the sewage cavity 31, so that the waste water is above the clean water cavity 33, and the filter assembly 32 is located at the bottom of the sewage cavity 31, so that the waste water penetrates into the clean water cavity 33 below under the action of gravity, and the suction action of the water and gas dual-purpose pump 4 further accelerates the penetration speed of the waste water into the clean water cavity 33.

[0043] The waste water box 1 and the water supply box 2 are arranged on the two sides of the filter box, so that the overall structure of the water supply and drainage device can be better adapted to other functional units of the nursing machine, for example, the waste water box 1 is located on one side of the dehumidification device, so as to facilitate direct collection of waste water, and the water supply box 2 is located on one side of the humidification device, which helps to shorten the pipeline layout and the like, thereby improving the rationality of the structure and the utilization rate of the space.

[0044] Preferably, as shown in the drawings, Figure 1 As shown, the filter assembly 32 of the utility model fills the inner cavity section of the filter box, so as to separate the inner cavity of the filter box into the sewage cavity 31 and the clean water cavity 33.

[0047] Through such an arrangement, the waste water can still be introduced into the sewage cavity 31 when the liquid level of the waste water in the waste water box 1 is low, so as to improve the recycling rate and utilization rate of the waste water and avoid the accumulation of bacteria in the waste water box 1.

[0048] Preferably, as shown in the drawings, Figure 1 Figure 1 As shown, the filter assembly 32 of the utility model is arranged as a filter screen and / or a reverse osmosis membrane and / or PP cotton.

[0052] Preferably, the water supply and drainage device further comprises a sterilization module assembly (not shown in the figure) arranged in the water supply box 2 and / or the filtering box and / or the wastewater box 1.

[0054] Preferably, the bottom of the wastewater box 1 is further provided with a drainage port (not shown in the figure), which can empty the wastewater. Through the arrangement, the wastewater box 1 can be emptied according to the need, so as to keep the wastewater box 1 clean and sanitary.

[0055] Preferably, the water supply box 2 is further provided with a water inlet (not shown in the figure), which can communicate with the external water source.
