According to statistics, the average hour of a common 1.5-piece air conditioner in a refrigeration state can generate 3 kilograms of condensed water, and the air filter screen 9 can be completely cleaned by the more condensed water.
The following describes the present invention with reference to fig. 1.
Example one
And a bracket or a guide groove is arranged between the lower part of the heat exchanger 3 and the upper part of the condensed water receiving tank 4 and is used for installing an air filter screen 9.
Preferably, in order to increase the filtering area of the air filter 9 and relatively reduce the air resistance, the air filter 9 is a folding air filter. The included angle between the air filter screen 9 and the horizontal plane is 0-65 degrees.
In order to make the condensed water disperse uniformly and drop on the airstrainer 9 and realize the cleaning of the whole airstrainer 9, the bottom of the heat exchanger 3 is set to be a structure which is beneficial to the condensed water disperse uniformly and drop on the airstrainer 9.
There are various structures that can achieve the dispersion and uniform dripping of the condensed water to the airstrainer 9. Alternatively, as shown in fig. 2 and 3, the fins on the bottom of the heat exchanger 3 are provided with flanges 21 or grooves 31 to guide the condensate water to fall uniformly. The shape of the flange 21 and the groove 31 is any shape such as triangle or quadrangle.
The distance between two adjacent flanges on the same fin is 5-20 mm.
The distance between two adjacent grooves on the same heat sink is 5-20 mm.
Example two
As shown in fig. 4, further, in order to clean the air filter screen more cleanly by the condensed water, a hydraulic cleaning device is provided; the water pressure cleaning device is started, the condensed water in the condensed water storage tank 42 is pressurized by the water pump 44, and then the air filter screen 9 is cleaned by the nozzle 46.
To achieve hydraulic cleaning of the airstrainer, the condensate of the heat exchanger 3 must be collected. In order to collect the condensed water of the heat exchanger 3 for hydraulic cleaning conveniently, the bottom of the heat exchanger 3 is a structure which has 1 or 2 low points and is beneficial to collecting the condensed water, and the bottom structure of the heat exchanger is similar to a V shape, or similar to an arc shape with an upward concave surface, or similar to an N shape, or similar to a W shape and the like under the condition of fully considering the efficiency of the structure of the heat exchanger 3 on the whole air conditioning system; preferably, the bottom of the heat exchanger is in a V-like shape with 1 or 2 low points, or in a concave-upward arc shape, or in a W-like shape, so that the condensed water of the heat exchanger 3 is concentrated to the low points, and the condensed water is convenient to collect. The bottom structure of the heat exchanger 3 shown in fig. 4 is a concave upward-facing arc-like structure.
Further, the hydraulic cleaning device comprises a condensed water storage tank 42, a storage tank water level monitoring device 43, a water pump 44, a liquid conveying pipe 45 and a nozzle 46.
Further, the air cleaner further comprises a filter screen dust deposition condition monitoring device 41, wherein the filter screen dust deposition condition monitoring device 41 monitors the dust deposition condition of the air filter screen 9, and judges whether the air filter screen 9 needs to be cleaned according to the dust deposition condition. Further, the filter dust deposition condition monitoring device 41 is a filter front-rear pressure difference detection device, and detects a pressure difference between the front and rear of the indoor air passing through the air filter 9 to determine the dust deposition condition of the air filter 9. With the increase of the dust deposition of the air filter 9, the pressure difference between the front and the rear of the air filter 9 is increased. When the dust accumulation of the air filter screen 9 increases to the degree of cleaning, the pressure difference between the front and the rear of the air filter screen 9 reaches the set value. When the filter dust situation monitoring device 41 monitors that the pressure difference between the front and the rear of the air filter 9 reaches a set value, a demand signal for cleaning the air filter 9 is automatically sent to the air conditioner control system.
Of course, the user of the air conditioner can also send a signal of the requirement for cleaning the air filter 9 to the air conditioner control system through the air conditioner remote controller.
Further, the condensed water storage tank 42 is located right below the low point of the bottom of the heat exchanger 3 and above the airstrainer 9, and is used for collecting the condensed water of the heat exchanger 3.
Further, the reservoir water level monitoring device 43 is configured to monitor the water level of the condensed water reservoir 42, including a set high water level and a set low water level, and send a water level signal to the air conditioning control system.
Further, a liquid delivery pipe 45 communicates the condensed water reservoir 42, the water pump 44, and the nozzle 46.
Furthermore, the nozzles 46 are fixed between the lower part of the heat exchanger 3 and the upper part of the air filter screen 9, and the openings of the nozzles face the filtering surface of the filter screen, and the number of the nozzles is 3-18.
The reservoir water level monitoring device 43 monitors the water level of the condensate water reservoir 42, and if the water level reaches a set high level, the water pump 44 of the water pressure cleaning device is started to clean the air filter screen 9 through the nozzle 46 by the water of the condensate water reservoir 42 if the air conditioning control system receives a demand signal for cleaning the filter screen. During the process of cleaning the air filter screen 9, the water level of the condensed water storage tank 42 is lowered, when the water level of the condensed water storage tank 42 is lowered to a set low water level, the water pressure cleaning process of the air filter screen 9 is finished, the air conditioning control system turns off the water pump 44 of the water pressure cleaning device, and the water pressure cleaning process is finished. After the water pressure cleaning process is finished, the air conditioner control system clears the original demand signal for cleaning the filter screen and monitors the demand signal for cleaning the filter screen again.
When the air conditioning control system receives a demand signal for cleaning the filter screen, if the condensate water storage tank 42 is not at the set high water level, the air conditioning control system does not start the water pressure cleaning device until the condensate water storage tank 42 is at the set high water level.
When the air conditioning control system does not receive the demand signal for cleaning the filter screen, and the condensate water storage tank 42 is at a high water level, the water pressure cleaning device is not started, the condensate water of the heat exchanger 3 continuously drops on the condensate water storage tank 42, the condensate water automatically overflows from the top of the condensate water storage tank 42, and the overflowed condensate water drops on the air filter screen at the lower part of the condensate water storage tank and then drops on the condensate water receiving tank 4.
Further, in order to improve the washing effect of the overflowing condensed water, the airstrainer 9 is arranged in a reverse V shape or an arc shape with a downward concave surface, and the top of the reverse V shape or the arc shape with the downward concave surface is right below the position where the condensed water overflows from the condensed water storage tank 42. Therefore, water overflowing from the condensed water storage tank 42 falls on the top of the air filter screen 9, and then is diffused to the whole air filter screen 9 from top to bottom, so as to drive dust on the air filter screen 9 to fall on the condensed water receiving tank 4.
An air conditioning system comprises any split air conditioner indoor unit.
