[0029] like Figure 1-Figure 4 As shown, the utility model provides an air conditioning cleaning system, including a rear protective net 200 and a water storage tank 100, wherein the rear protective net 200 includes a plurality of first pipes 201 interconnected with each other, and a plurality of spray holes 2011 are arranged on the first pipes 201. The rear protective net 200 is arranged on one side of the outdoor unit housing and connected to the outdoor unit housing. The water inlet of the water storage tank 100 is connected to the condensate water drain pipe of the indoor unit, and the water outlet of the water storage tank 100 is used to connect to the water inlets of the plurality of first pipes 201, and the water storage tank 100 is used to pressurize the condensate water of the indoor unit and spray it out from the spray holes 2011 of the first pipes 201.
[0030] It should be noted that the rear protective net 200 is composed of a plurality of first pipes 201 interconnected with each other. The rear protective net 200 is arranged on one side of the condenser in the outdoor unit 10, and the spray holes 2011 on the first pipes 201 thereof face the condenser, so that when the rear protective net 200 is sprayed, condensed water can flow out from the spray holes 2011 and shoot toward the condenser.
[0031] The outdoor unit housing includes a front wall and side walls arranged around the edge of the front wall, the rear guard net 200 is arranged parallel to the front wall, and the edges of the rear guard net 200 are respectively connected to the side walls. That is, the rear guard net 200 and the outdoor unit housing together constitute the outer shell of the outdoor unit, and the condenser, pipes, motor and fan are all arranged in the outdoor unit.
[0032] The condensed water in the water tank 100 comes from the evaporator condensed water of the indoor unit. The condensed water in the water tank 100 is generally pressurized by a water pump 103, which sends the condensed water to the first pipe 201 and is sprayed onto the condenser through the spray hole 2011 of the first pipe 201.
[0033] Based on the above description, it can be understood that, compared with the prior art, on the one hand, the rear protective net 200 can protect the internal components of the outdoor unit while directly flushing away the dust and impurities on the condenser through spraying; on the other hand, it can also create conditions for the formation of a thicker frost layer on the condenser when the relative humidity of the external environment is low, thereby achieving a better cleaning effect of "condensation-frosting-defrosting-drying".
[0034] In some embodiments, the water inlet of the water storage tank 100 can also be connected to other water supply sources to ensure that the rear protective net 200 has enough spray water to spray the condenser when the condensate water of the indoor unit is insufficient. That is, the water inlet of the water storage tank 100 is connected to the condensate drain pipe of the indoor unit and other water supply sources at the same time.
[0035] In some embodiments, the first pipe 201 is a vertical pipe section with both ends closed. A plurality of spray holes 2011 arranged at intervals are provided on the pipe body so that condensed water can be sprayed out from the first pipe 201 .
[0036] In some embodiments, a refrigeration unit 101 is further disposed in the water tank 100 , and the refrigeration unit 101 is used to cool the condensed water stored in the water tank 100 .
[0037] It should be noted that the refrigeration unit 101 may use a semiconductor refrigeration sheet, which can quickly cool the condensed water in the water storage tank 100, so that the temperature of the condensed water sprayed out by the rear protective net 200 is lower and it is easier to frost on the condenser.
[0038] In some embodiments, a filter screen 102 is disposed below the water inlet of the water storage tank 100 , and the filter screen 102 is used to filter the condensed water entering the water storage tank 100 .
[0039] It is understandable that by setting a filter net 102 below the water inlet of the water tank 100, the condensed water entering the water tank 100 from the condensed water drain pipe can be filtered to prevent impurities from entering the water tank 100 and causing blockage of the spray system.
[0040] In some embodiments, the filter 102 is pluggable and plugged into the water tank 100. That is, the filter 102 and the water tank 100 are connected and separated by plugging and unplugging. Based on this, it is convenient to replace the filter 102 in time to ensure the filtering effect of the filter 102.
[0041] Specifically, the filter 102 includes a mesh body and a frame portion, the mesh body portion is arranged on the frame portion, an insertion hole is arranged on one side wall of the water tank 100, and the frame portion is plugged into the water tank 100 through the insertion hole, thereby realizing the plugging of the filter 102 and the water tank 100.
[0042] More specifically, the mesh body portion, namely the mesh body of the filter 102, is hung on the frame portion via a hook disposed on the frame portion.
[0043] In some embodiments, an overflow hole is provided on the side wall of the water tank 100 , and the overflow hole is close to the top of the water tank 100 .
[0044] It can be understood that the overflow hole is used to overflow when there is too much condensed water in the water storage tank 100, so as to avoid the condensed water from flowing back due to the condensed water being full in the water storage tank 100.
[0045] In some embodiments, the water tank 100 is a rectangular parallelepiped structure, and overflow holes are provided on the four side walls of the water tank 100, and the four overflow holes are located at the same height of the side walls.
[0046] In some embodiments, the overflow hole is externally connected to other pipes, and the other pipes are used to collect excess condensed water in the water storage tank 100 .
[0047] In some embodiments, a water pump 103 is disposed in the water tank 100 , and the water pump 103 is used to pressurize the condensed water in the water tank 100 and flow it toward the rear protective net 200 .
[0048] It is understandable that the water pump 103 can pressurize the liquid when conveying it, so that the water flow has energy to be ejected from the injection port of the first pipe 201 .
[0049] In some embodiments, the rear protective net 200 also includes at least one second pipe 202, and multiple first pipes 201 are arranged at intervals along the first direction. Each first pipe 201 is connected to the same second pipe 202, and the water inlet of the second pipe 202 is connected to the water outlet of the water tank 100.
[0050] The second pipe 202 is arranged along the first direction and communicated with each first pipe 201 to transport the condensed water in the water storage tank 100 to the first pipe 201 .
[0051] In some embodiments, the spray includes two second pipes 202 , both of which are arranged along the first direction, each of the second pipes 202 is connected to all the first pipes 201 , and each of the second pipes 202 is connected to the water outlet of the water tank 100 .
[0052] In some embodiments, the air conditioning cleaning system includes a humidity sensor 300 and a controller 500. The humidity sensor 300 is used to monitor the relative humidity of the environment in which the outdoor unit 10 is located and provide feedback to the controller 500. The controller 500 is used to determine whether to start the air conditioning cleaning system and use the rear protective net 200 for spraying based on the relative humidity of the environment in which the outdoor unit 10 is located.
[0053] For example, the humidity sensor 300 monitors that the relative humidity of the environment in which the outdoor unit 10 is located is 60%, and feeds back the relative humidity of 60% to the controller 500. The controller 500 determines that the relative humidity of 60% is less than the preset relative humidity of 80%, and the controller 500 controls the rear protective net 200 to spray the condenser.
[0054] The controller 500 is connected to the water pump 103 of the water tank 100, and the controller 500 controls the start and stop of the water pump 103 to control whether the rear protective net 200 is sprayed.
[0055] In some embodiments, the air conditioning cleaning system further includes a temperature sensor 400, which is used to monitor the temperature of the outdoor heat exchange coil, and the controller 500 is used to determine whether to close the rear protective screen 200 according to the temperature of the outdoor heat exchange coil.
[0056] It is understandable that after the controller 500 controls the rear protective screen 200 to spray for a certain period of time, it determines whether the air conditioning cleaning system needs to be shut down based on the temperature feedback from the outdoor heat exchange coil.
[0057] For example, after the rear protective net 200 has been spraying for 3 minutes, the temperature sensor 400 detects that the temperature of the outdoor heat exchange coil is -15°C and feeds it back to the controller 500. The controller 500 compares the outdoor heat exchange coil temperature at this time with the preset frost temperature of -5°C, and controls the rear protective net 200 to stop spraying according to the comparison result.
[0058] In some embodiments, the utility model further provides an air conditioner, which includes the air conditioner cleaning system in the above embodiments. Since the air conditioner cleaning system includes the air conditioner cleaning system in at least one of the above embodiments, the air conditioner cleaning system has at least some or all of the beneficial effects of the above air conditioner cleaning system embodiments, which will not be described one by one here.
[0059] In some embodiments, the air conditioner includes an outdoor unit 10, the outdoor unit 10 has an outdoor unit housing, and the water storage tank 100 is arranged in the housing of the outdoor unit. The outdoor unit housing includes a front wall and a side wall arranged around the edge of the front wall, the rear guard net 200 is arranged parallel to the front wall, and the edges of the rear guard net 200 are respectively connected to the side walls. That is, the rear guard net 200 and the outdoor unit housing together constitute the outdoor unit housing part, and the condenser, pipes, motors, fans, etc. are all arranged in the outdoor unit. A plurality of first pipes 201 are arranged on one side of the condenser of the outdoor unit 10.
[0060] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the application concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
