In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] As Figures 1 to 2 shown, an embodiment of the first aspect of the present utility model provides a wet film humidification and water-saving device. The wet film humidification and water-saving device includes an evaporator 1, an evaporation water storage member 2, a wet film humidifier 3, and a wet film water storage member 4. The evaporation water storage member 2 is arranged below the evaporator 1 and is used to collect the condensed water of the evaporator 1. The evaporator 1 will generate condensed water during the working process. If these condensed waters are not processed, it may cause equipment damage or environmental problems. Through the evaporation water storage member 2, these condensed waters can be effectively collected and discharged, avoiding the overflow of condensed water droplets or damage to the equipment.

[0036] The water inlet of the wet film humidifier 3 is connected to the water outlet of the evaporation water storage member 2 through a first pipeline 5. A water supply pump 7 is provided on the first pipeline 5. The water supply pump 7 can be selectively connected to the water inlet of the wet film humidifier 3, so as to pump the water in the evaporation water storage member 2 into the water inlet of the wet film humidifier 3 through the first pipeline 5. The wet film water storage member 4 is arranged below the wet film humidifier 3 and is used to collect the discharged water of the wet film humidifier 3. The water outlet of the wet film water storage member 4 is connected to the water inlet of the evaporation water storage member 2 through a second pipeline 6, so that the water in the wet film water storage member 4 can flow into the evaporation water storage member 2 through the second pipeline 6.

[0037] With such a setting, the condensed water generated after the evaporator 1 works will fall into the evaporation water storage member 2. The condensed water in the evaporation water storage member 2 will be pumped into the water inlet of the wet film humidifier 3 through the first pipeline 5 by the water supply pump 7. The condensed water can be recycled for the second time for humidifying the wet film on the wet film humidifier 3. The discharged water of the wet film humidifier 3 can fall into the wet film water storage member 4. The discharged water in the wet film water storage member 4 can be introduced into the evaporation water storage member 2 through the second pipeline 6. The discharged water and condensed water in the evaporation water storage member 2 will be mixed and pumped back into the water inlet of the wet film humidifier 3 through the first pipeline 5 by the water supply pump 7 for recycling, forming a circulating water path, reducing the input amount of external water, and also collecting and recycling the condensed water of the evaporator 1 and the excess unevaporated water in the wet film humidifier 3, reducing water resource waste, and solving the problem in the related art that the wet film humidifier 3 of the air conditioner needs to add external water and part of the water will be discharged outside the air conditioner after use, resulting in serious water resource waste.

[0038] As Figures 1 to 3 shown, in some embodiments, a filter 8 is provided on the first pipeline 5. The filter 8 is arranged between the water supply pump 7 and the water outlet of the evaporation water storage member 2. The condensed water flowing out of the evaporation water storage member 2 is filtered by the filter 8 and then enters the water supply pump 7 for transportation, reducing the damage of impurities to the water supply pump 7, and also reducing the impurities being pumped into the wet film humidifier 3 to damage the wet film, improving the service life of the water supply pump 7 and the wet film humidifier 3.

[0039] As Figures 1 to 3 shown, further, a tee 9 is provided on the first pipeline 5. The tee 9 has a first water inlet, a second water inlet and a water outlet. The water outlet of the evaporation water storage member 2 is connected to the first water inlet of the tee 9. The second water inlet of the tee 9 can be selectively connected to an external water source. The water outlet of the tee 9 is connected to the water inlet of the filter 8. With such a setting, by providing the tee 9 on the first pipeline 5, an external water source can be selectively introduced, reducing the occurrence of insufficient water flowing into the wet film humidifier 3. Moreover, the tee 9 is arranged at the upstream water inlet position of the filter 8. The water entering through the tee 9 will enter the filter 8 for filtration and then flow into the wet film humidifier 3, reducing the entry of impurities.

[0040] As shown Figures 1 to 3 in the figure, further, the wet film humidification water-saving device further includes a flow sensor 10 and a switching valve 11. The flow sensor 10 is used to detect the water inflow of the wet film humidifier 3 so as to monitor in real time whether the wet film humidifier 3 is short of water. The switching valve 11 is arranged at the water inlet position of the tee 9, and the switching valve 11 can be opened to allow external water source to enter. With such a setting, during use, when the flow sensor 10 detects that the water inflow of the wet film humidifier 3 is lower than the preset water inflow, the water inflow of the wet film humidifier 3 is significantly insufficient, and the switching valve 11 can be opened to introduce external water source to supplement the water inflow of the wet film humidifier 3. When the flow sensor 10 detects that the water inflow of the wet film humidifier 3 is equal to or higher than the preset water inflow, the water inflow of the wet film humidifier 3 can meet the humidification requirement, and the switching valve 11 can be closed, and the external water source stops being introduced.

[0041] Among them, the preset water inflow can be selected according to the area of the wet film humidifier 3 and the humidification work requirement.

[0042] Further, the wet film humidification water-saving device further includes a controller. The flow sensor 10, the switching valve 11 and the water supply pump 7 are all communicatively connected to the controller. The controller can preset parameter values such as the water inflow. The water inflow signal output by the flow sensor 10 can be transmitted to the controller, and the controller can output a switching signal to the switching valve 11 to adjust the opening and closing states of the switching valve 11, and output a driving signal to the water supply pump 7 to adjust the water supply speed of the water supply pump 7 so as to quickly reach the water inflow required by the wet film humidifier 3.

[0043] In some embodiments, the evaporation water storage member 2 is configured as a housing with an opening. An overflow port is provided on the side wall of the housing. The distance from the overflow port to the opening is less than the distance from the overflow port to the bottom of the housing. With such a setting, the opening of the housing can allow the condensed water on the evaporator 1 to fall in, and the overflow port can be connected to an external device through a pipeline to facilitate the discharge of excess water, reduce the excessive inflow of water in the evaporation water storage member 2 into the device interior, and the overflow port is arranged close to the opening position to ensure that the housing has sufficient water storage capacity while preventing water from flowing out of the opening of the housing.

[0044] Among them, the distance from the overflow port to the opening is one-third of the height of the housing, which ensures that the housing has sufficient water storage capacity while preventing water from flowing out of the opening of the housing.

[0045] As shown Figures 1 to 3 in the figure, in some embodiments, the wet film water storage member 4 is located above the evaporation water storage member 2, and the wet film humidifier 3 is erected above the wet film water storage member 4 so that the water discharged from the wet film humidifier 3 can smoothly fall into the evaporation water storage member 2, and the water in the wet film water storage member 4 can smoothly flow into the evaporation water storage member 2 under its own gravity through the second pipeline 6.

[0046] As Figures 1 to 3 shown, in some embodiments, the water supply pump 7 has a pump inlet 71 and a pump outlet 72. The pump inlet 71 is disposed on the side wall of the water supply pump 7 facing the evaporation water storage member 2, and the pump outlet 72 is disposed at the top of the water supply pump 7, so that the water supply pump 7 can be disposed at the corner position of the first pipeline 5. The pump outlet 72 of the water supply pump 7 directly pumps water out in the vertical direction, reducing the pressure loss of the water supply pump 7 at the corner position.

[0047] In some embodiments, a bracket is disposed on the side wall of the evaporator 1, and the wet film humidifier 3 is mounted on the air inlet side of the evaporator 1 through the bracket, so that the wet film humidifier 3 is stably mounted on the evaporator 1. After passing through the wet film humidifier 3, the gas can be stably mounted on the evaporator 1. There is a distance between the side wall of the wet film humidifier 3 and the side wall of the evaporator 1, so that the gas passing through the wet film humidifier 3 can be dispersed into each air inlet channel of the evaporator 1.

[0048] As Figures 1 to 4 shown, an embodiment of the second aspect of the present invention provides an air conditioner, including a housing and the wet film humidification and water saving device in any of the above solutions. The wet film humidification and water saving device is disposed in the housing. Both the wet film humidifier 3 and the evaporator 1 are connected to the housing. By providing the wet film humidification and water saving device in the air conditioner, the condensed water generated after the evaporator 1 works will fall into the evaporation water storage member 2. The condensed water in the evaporation water storage member 2 will be pumped into the water inlet of the wet film humidifier 3 through the water supply pump 7 via the first pipeline 5. The condensed water can be used for secondary recovery of the wet film humidification on the wet film humidifier 3. The discharged water of the wet film humidifier 3 can fall into the wet film water storage member 4. The discharged water in the wet film water storage member 4 can be introduced into the evaporation water storage member 2 through the second pipeline 6. The mixture of the discharged water and the condensed water in the evaporation water storage member 2 will be pumped into the water inlet of the wet film humidifier 3 again through the water supply pump 7 via the first pipeline 5 for recycling, forming a circulating water path, reducing the input amount of external water, and also collecting and recycling the condensed water of the evaporator 1 and the excess unevaporated water in the wet film humidifier 3, reducing water resource waste.

[0049] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not limitations on the embodiments of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
