[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The present invention provides a cleaning device and a cleaning method for an air-to-water maker 1, as Figures 1 to 3 shown, for cleaning the water storage tank 2, the instant cooler 3, the instant heater 4 and the internal water pipeline.

[0035] The cleaning device used in this cleaning method includes several water pumps, several switching valves and pipelines. The cleaning device also includes a detachable and easily replaceable cleaning bucket. Refer to Figure 3 , the cleaning bucket is placed outside the air-to-water maker 1, which is convenient for users to replace or clean it at any time according to needs.

[0036] The air-to-water maker 1 is provided with an external water inlet and a cleaning drain outlet. The external water inlet is used to connect to a clean water source outside the air-to-water maker 1. The external water inlet is inserted into the external cleaning bucket through a pipeline to connect the clean water in the cleaning bucket to the cleaning system. The air-to-water maker 1 also has an internal water inlet, which is used to connect to the internal water flow of the air-to-water maker 1, such as drinking water from a water collection device.

[0037] A first switching valve and a first water pump are provided between the cleaning water inlet and the water storage tank 2. The first switching valve can switch the input from the internal water inlet or the external water inlet to the water storage tank 2. When it is necessary to use the external clean water source for equipment cleaning, the external water inlet becomes the first choice; while in daily operation, the internal water inlet is responsible for replenishing water to the water storage tank 2. A second water pump and a second switching valve are provided on the water pipeline of the water storage tank 2 leading to the instant cooler 3 and the instant heater 4. The second switching valve can switch to open to the instant cooler 3 or the instant heater 4. A third switching valve is provided on the water pipeline of the instant cooler 3 and the instant heater 4 leading to the water storage tank 2. The third switching valve can switch to open to the fourth switching valve or the water outlet. A fourth switching valve is provided on the water pipeline of the third switching valve leading to the cleaning drain outlet. The fourth switching valve can switch to open to the water return sterilization channel or the pipeline cleaning channel. Among them, the water return sterilization channel is connected to the water storage tank 2, and the pipeline cleaning channel is connected to the cleaning drain outlet. When the pipeline cleaning channel is selected, the clean water in the instant cooler 3 and the instant heater 4 and the residual water in the pipeline will be discharged smoothly and flow back to the cleaning bucket through the cleaning drain outlet.

[0038] In this embodiment, the first switching valve, the second switching valve, the third switching valve, and the fourth switching valve adopted are all high-performance two-way switching valves. This design of two-way switching valves enables the water flow to freely switch between two directions, thus meeting the requirements of different water circuit configurations during the cleaning and operation processes.

[0039] In addition, in order to achieve precise monitoring and management of the water flow rate during the cleaning process, this embodiment also selectively sets flow meters on key water pipelines. Specifically, a first flow meter is set between the first water pump and the water storage tank 2, which can monitor and record in real time the water flow rate flowing into the water storage tank 2 from the external water inlet or the internal water inlet. Similarly, a second flow meter is also set in the water circuit between the second water pump and the second switching valve, for precisely measuring the water flow rate flowing to the instant cooler 3 or the instant water heater 4.

[0040] A filtering device is also provided between the first water pump and the water storage tank 2. The filtering device includes a cleaning valve and a filter 5. The cleaning valve is a two-way switching valve, and the cleaning valve can be switched to open to the water storage tank 2 or the filter 5. The filter 5 is connected to the water storage tank 2. When the cleaning valve is directly switched to open to the water storage tank 2, the cleaning channel is connected, and the water flow directly leads to the water storage tank 2; if the cleaning valve is switched to open to the filter 5, the water supply channel is connected, and the water flow first passes through the filter 5 and then flows to the water storage tank 2.

[0041] The water storage tank 2 is internally provided with a UVC LED sterilization device for ultraviolet sterilization of the water in the water storage tank 2. The water storage tank 2 is also externally connected with an ozone sterilization device for ozone sterilization of the water in the water storage tank 2. The ozone sterilization device includes an ozone generator and an ozone air pump. If the fourth switching valve is switched to open to the water return sterilization channel, the water flow in the instant cooler 3 and the instant water heater 4 flows to the sterilization devices in the water storage tank 2 and is successively subjected to double sterilization treatments by the UVC LED sterilization device and the ozone sterilization device.

[0042] The cleaning method of the air-to-water generator 1 of the present invention is as follows (refer to Figure 3 ):

[0043] The cleaning method includes the following steps:

[0044] 1. Enter the "cleaning mode", the second switching valve is switched to the "external water inlet" input, and the cleaning valve is switched to the "cleaning channel" output; the first water pump is turned on; the internal UVC LED sterilization device is turned off, the second water pump is turned on, the second switching valve is alternately switched to open to the instant cooler and the instant water heater, the third switching valve is switched to open to the fourth switching valve, and the fourth switching valve is switched to open to the clean drain port, that is, switched to open to the "pipe cleaning channel";

[0045] 2. Under the action of the first water pump and the second water pump, the water in the water storage tank, the instant cooler, the instant water heater, and the water pipeline is discharged;

[0046] 3. Fill the cleaning water into an external cleaning bucket.

[0047] 4. Insert the "external water inlet" of the air water making system into the cleaning water in the cleaning bucket through a pipeline.

[0048] 5. Connect the "clean drainage port" of the air water making system to the upper part inside the cleaning bucket through a pipeline.

[0049] 6. Under the action of the first water pump and the second water pump, the cleaning water is pumped out from the cleaning bucket, enters the water pipeline, water storage tank, immediate cooler, and immediate heater of the air water system, and then is discharged from the clean drainage port and flows back to the cleaning bucket. In this way, the automatic cyclic cleaning of the water pipeline, water storage tank, immediate cooler, and immediate heater of the air water making system can be realized.

[0050] In step 4, it is optional to directly connect the "external water inlet" of the air water making system to clean water through a pipeline, rather than necessarily connecting to the clean water from inside the cleaning bucket.

[0051] In step 6, under the action of the first water pump and the second water pump, the clean water directly flows in from the "external water inlet", enters the water pipeline, water storage tank, immediate cooler, and immediate heater of the air water making system, and then is discharged from the "clean drainage port", achieving the effect of cleaning the water pipeline, water storage tank, immediate cooler, and immediate heater of the air water making system. This step can be carried out several times to achieve a thorough cleaning effect.

[0052] The normal water making process of the air water maker 1 of the present invention is as follows:

[0053] Select to enter the "water supply mode", the first switching valve switches to the internal water inlet for input, the cleaning valve switches to open to the water supply channel, the first water pump is turned on, and the drinking water inside the air water maker 1 (such as the water collection device) is pumped from the internal water inlet, and the water flow flows from the water supply channel to the filter 5 and then to the water storage tank 2; at this time, the internal UVC LED sterilization device and the ozone sterilization device are in the open state.

[0054] The second water pump is turned on, and the second switching valve alternately switches to open to the immediate cooler 3 and the immediate heater 4, and the drinking water in the water storage tank 2 is alternately pumped into the immediate cooler 3 and the immediate heater 4.

[0055] The third switching valve switches to open to the water outlet, and the drinking water directly flows out from the water outlet; or the third switching valve switches to open to the fourth switching valve, and the fourth switching valve switches to open to the water return sterilization channel, and the drinking water flows to the UVC LED sterilization device for sterilization and then passes through the immediate heater 4 or the immediate cooler 3 and is discharged from the water outlet.
