The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
The following detailed description of embodiments of the invention is provided in conjunction with the appended drawings:
in the case of the example 1, the following examples are given,
as shown in fig. 1 to 3, the cleaning device for the heat pump heat exchanger fins is mounted on an external unit 5 of a heat pump system, and comprises a water collecting tank 1, a water pump 2, a water delivery pipe 3 and a spraying device 4, wherein a water outlet 6 is arranged at the bottom of the external unit 5 of the heat pump system to prevent water from accumulating in the internal space of the external unit. The water collecting tank 1 is fixedly arranged below the outer part of an outer machine 5 of the heat pump system through bolts, is positioned below a water outlet 6 and is communicated with the inner space of the outer machine; meanwhile, the detachable filter screen is arranged at the upper half part of the inner space of the water collecting tank 1, a water outlet is formed in one side of the bottom of the water collecting tank 1, and the outer end of the water outlet is communicated with a water inlet end 8 of the water pump 2 through a water pipe. The water pump 2 is fixedly arranged beside the external machine 5 of the heat pump system through a base, and the water outlet end 9 of the water pump 2 is fixedly connected with one end of the water delivery pipe 3; the water delivery pipes 3 are arranged along the edge of the side wall of the outer machine, and the other ends of the water delivery pipes are fixedly connected to the water inlet of the spraying device 4. The spraying device 4 is fixedly arranged at the top of a heat exchanger in the external machine 5 of the heat pump system and comprises a spraying pipe and a fixing structure thereof, and the setting length of the spraying pipe is slightly smaller than the width of the heat exchanger; a plurality of spraying holes are equidistantly arranged on the spraying pipe along the length direction, corresponding spraying nozzles are fixedly arranged at the outer end parts of the spraying holes, the spraying nozzles are opposite to gaps of the heat exchanger fins 7, and the spraying areas of the spraying nozzles are staggered with each other, so that full coverage is achieved.
A water level detection sensor is also arranged in the water collecting tank 1 and used for detecting the amount of water in the water collecting tank 1 in real time; the water pipe 3 is also provided with a water flow sensor for detecting the continuous water flow in the water pipe in real time. The water level detection sensor and the water flow sensor are respectively connected with a main control board of the heat pump system through signals, so that automatic control is facilitated.
As a further optimized technical scheme of the invention, in order to ensure the normal water flow in the water collection tank 1 and prevent the freezing phenomenon caused by low outdoor temperature in winter, the outer side of the tank wall of the water collection tank 1 is also wrapped and installed with a heat insulation layer with the thickness of more than 15 mm.
When the heat pump is used, an intermittent defrosting process is generated, the temperature of the heat exchanger fins 7 can be increased in the defrosting process, frost on the fins can be melted to flow down, the frost is accumulated at the bottom of the external machine and enters the water collecting tank 1 below through the water outlet 6, when the water storage amount in the water collecting tank 1 reaches the highest water level of the water level detection sensor, the signal is transmitted to the main control board of the heat pump system, and the main control board of the heat pump system receives the signal and then controls the water pump 2 to start to pump water. Water in the water collecting tank 1 is conveyed into a spraying device 4 through a water pump 2 and a water conveying pipe 3, water flow with high water pressure and high flow speed is sprayed out of the spraying pipe, the water flow directly washes the fins 7 of the heat exchanger, dust and impurities on the fins are washed away, and the purpose of washing the fins is achieved. And because the length of the spray pipe is smaller than the width of the heat exchanger, when the fins are cleaned, water flow only flows through the fins to take away stains and does not splash onto the fan motor, the situations of accidental electric leakage, short circuit and the like are reduced, and the normal use of the fan blade 10 driven by the fan motor is ensured. The flushed water flow carries dust and sundries to enter the water collecting tank 1 through the water outlet 6 again, the dust, the sundries and the like flushed down are filtered by the filter screen arranged in the water collecting tank, the water flow enters the lower part of the water collecting tank 1, the recycling is finished, and the waste of water resources is avoided.
When the water flow sensor arranged on the water pipe 3 detects that the continuous water flow in the water pipe is smaller than a set value, the signal is transmitted to the main control board of the heat pump system, and the water pump control system arranged on the main control board stops the operation of the water pump so as to prevent the water pump from being burnt out due to idling.
As a further optimized technical scheme of the invention, the side wall of the upper part of the water collecting tank 1 is also provided with an outer water injection port so as to meet the requirement of part of users for actively cleaning fins.
