[0036] Example 1

[0037] This embodiment provides an automatic cleaning device for a mobile air conditioner, such as Figure 1-Figure 3 As shown, the concrete includes a water pump 1, a sprinkler 2 and a water pipe 3. The mobile air conditioner is equipped with an evaporator 6 and a condenser 7. The evaporator 6 is arranged above the condenser 7, and the length of the evaporator 6 is connected to the chassis 4 The length direction is the same, the length direction of the condenser 7 is perpendicular to the length direction of the chassis 4, one end of the water pipe 3 is set in the chassis 4, and the condensation water generated by the mobile air conditioner during operation falls into the chassis 4, and the water pipe 3 is set in the chassis 4 One end is set in the water receiving pan of the chassis 4, and the other end of the water pipe 3 is connected to the sprinkler pan 2. The sprinkler pan 2 is set on the top of the evaporator 6 and the condenser 7. Preferably, in the present embodiment, the condenser 7 and the evaporator 6 There is a sprinkler pan 2 on the top of the water pipe, and a water pump 1 is set in the middle of the water pipe 3. The water pump 1 can pump the condensate collected in the chassis 4 into the sprinkler pan 2, and the condenser 7 and the evaporator 6 are cleaned by the sprinkler pan 2. In this embodiment, the water pump 1 is fixed on the side of the condenser 7 close to the compressor through the connecting frame 11.

[0038] The sprinkler pan 2 of this embodiment includes a first sprinkler pan 21 and a second sprinkler pan 22. The first sprinkler pan 21 is arranged at the top of the evaporator 6. The shape of the first sprinkler pan 21 matches that of the evaporator 6. The pan 21 is provided with a first water leakage hole 211. There are multiple first water leakage holes 211. The multiple first water leakage holes 211 are evenly distributed in the first sprinkler pan 21. The water pump 1 pumps the condensed water in the first sprinkler pan 21. The evenly divided first water leakage hole 211 flows into the fins of the evaporator 6 to ensure that the entire evaporator 6 is washed with water. The condensed water after cleaning the evaporator 6 will flow into the second sprinkler 22, which is used in the mobile air conditioner. After cleaning the condensed water of the evaporator 6, the condenser 7 can be cleaned; the second sprinkler pan 22 is arranged between the condenser 7 and the evaporator 6, and the second sprinkler pan 22 is arranged on the top of the condenser 7. The second sprinkler tray 22 is provided with second water leakage holes 221. There are multiple second water leakage holes 221. The multiple second water leakage holes 221 are evenly distributed in the second sprinkler tray 22. The multiple second water leakage holes 221 are all distributed in the condensation Directly above the condenser 7, the condensed water pumped by the water pump 1 to the second sprinkler pan 22 and the condensed water flowing from the evaporator 6 flows into the fins of the condenser 7 through the evenly divided second water leakage holes 221 to ensure that The entire condenser 7 is washed with water.

[0039] The automatic cleaning device for a mobile air conditioner described in this embodiment uses an independent water pump 1 to pump the condensed water in the chassis 4 to the top of the condenser 7 and the evaporator 6, and connects the condenser 7 and the evaporator 6 through the sprinkler 2 For cleaning, it does not rely on an external cleaning water source, the water source can be recycled, and the cleaning function can be realized without the user's disassembly of the machine.

[0041] The difference between this embodiment and the above-mentioned embodiment lies in the combination of image 3 versus Figure 4 As shown, the mobile air conditioner automatic cleaning device also includes a water level switch 5 and a control module. The control module receives the on or off signal transmitted by the water level switch 5 and controls the on or off of the water pump 1. The control module is electrically connected to the water pump 1, and the control module can send The turn-on or turn-off command is sent to the water pump 1 to control the turn-on and turn-off of the water pump 1. The water level switch 5 is set in the chassis 4 to detect the water level of the condensate in the chassis 4, and the water level switch 5 is electrically connected to the control module. The switch 5 transmits the detected water level height to the control module for judgment and control. Preferably, there are two water level switches 5, the first water level switch 51 is set with the first trigger water level L1, and the second water level switch 52 is set There is a second trigger level L2, the height of the first trigger level L1 is higher than the height of the second trigger level L2, the port of the water pipe 3 arranged in the chassis 4 is lower than the second trigger level L2, and the height of the condensate water level is greater than or equal to When the water level L1 is first triggered, the control module will send an open command to the water pump 1 to control the water pump 1 to turn on, to ensure that the water pump 1 is turned on when there is enough water in the condensate to prevent insufficient cleaning caused by insufficient water, at the height of the condensate water level When it is less than the first trigger water level L1, the control module does not send a start command to the water pump 1. The control module controls to start the cooling mode or dehumidification mode until the condensate water level in the chassis 4 is greater than the first trigger water level L1, and the water pump 1 is turned on for cleaning. During the cleaning process, when the water level of the condensate is less than the second trigger level L2, the control module sends a shutdown command to the water pump 1 to control the water pump 1 to close, so as to prevent the water pump from idling and damage when the water volume is insufficient.

[0042] When setting the first trigger level L1 and the second trigger level L2, it should be ensured that the amount of water in the chassis 4 between the height of L2 and the height of L1 is less than the water pipe 3, the sprinkler tray 2, and the fins of the evaporator 6 and the condenser 7 are being cleaned The total amount of condensate water ensures that after the water pump 1 works for a period of time, the condensate water level in the chassis 4 will be less than the height of the second trigger water level L2, otherwise it will be impossible to judge and control the water pump 1 to shut down.

[0044] The difference between this embodiment and the above-mentioned embodiment lies in the combination of figure 1 versus Figure 5 As shown, the mobile air conditioner automatic cleaning device also includes a wind pressure sensor 8, which is arranged in the upper air duct and the lower air duct of the mobile air conditioner, and the wind pressure sensor 8 is electrically connected to the control module. Preferably, this embodiment is in the upper air duct. The wind pressure sensor is provided with the lower air duct. The wind pressure sensor 8 includes a first wind pressure sensor 81 and a second wind pressure sensor 82. The first wind pressure sensor 81 is arranged in the upper air duct to detect the first wind at the air outlet. The second wind pressure sensor 82 is arranged in the downwind duct to detect the second wind pressure information at the entrance and exit, and transmit the first wind pressure information and the second wind pressure information to the control module, and the control module detects the first When one of the wind pressure information and the second wind pressure information is less than the preset wind pressure value, it is determined that dust is adsorbed in the fin gaps of the evaporator 6 and the condenser 7 at this time, and the control module further controls the opening and closing of the water pump 1.

[0045] Preferably, the mobile air conditioner also includes a warning light. When the control module detects that one of the first wind pressure information and the second wind pressure information is less than the preset wind pressure value, it sends an on command to the warning light, and the warning light turns on and reminds the user Turn on the water washing function, and the mobile air conditioner further controls the opening and closing of the water pump 1.
