The atomizing assembly 2 includes a water tank 21, and controls the amount of water flowing into the water tank 21 from a water storage tank 31 through a water level control valve 24, and also pumps condensed water from a water receiving tray 32 into the water tank 21 through a water pump. In this way, the atomizing assembly 2 can obtain a water source from the water storage tank 31 above, and can also obtain a water source from the water receiving tray 32 receiving condensed water below.
The outlet of the water tank 21 is in butt joint with the inlet of the delivery pipe 5. The ultrasonic vibrator 22 and the blower 23 are both disposed at the water tank 21, more specifically, the blower 23 is disposed above the water tank 21 and faces the inlet of the conveying pipe 5, and the ultrasonic vibrator 22 is disposed at the bottom of the water tank 21, so that mist is formed in the water tank 21 after the ultrasonic vibrator 22 works, and the blower 23 works to blow the mist into the conveying pipe 5.
Finally, mist is sprayed out from each mist outlet 63 of the mist outlet pipe 6, and then when the cross-flow fan blades 1 rotate, the humidifying mist rotates along with the cross-flow fan blades 1, so that the humidifying mist and the outdoor air passing through the evaporator are fully mixed and are conveyed out together, the humidifying is more uniform, the humidifying range is wider, and the humidifying efficiency and the human comfort are improved.
More importantly, the blades 17 of the lower cross-flow fan blade 1 are kept to be of normal thickness and complete air guiding surface, so that the air supply effect of the air conditioner is ensured, and the load and the energy consumption of the motor 19 are not influenced.
Control method embodiment of air conditioner
The control method of the air conditioner is realized based on the air conditioner embodiment.
The atomizing subassembly 2 adopts ultrasonic oscillator 22 to remove the atomizing, so, opens ultrasonic oscillator 22 and can realize atomizing humidification, closes ultrasonic oscillator 22 and can realize after opening the water pump that the clear water sprays to wash the heat exchanger.
The control method of the air conditioner comprises the following steps:
if the first control instruction is acquired, entering an atomization mode; and if the second control instruction is acquired, entering a cleaning mode.
In the atomizing mode, the ultrasonic oscillator 22 is controlled to work, and the cross-flow fan blade 1 is controlled to rotate at a higher first rotation speed. The system can determine whether to supply water by using the water receiving disc 32 or the water storage tank 31 according to the water level detection signal of the water receiving disc 32, for example, when the water level detection signal of the water level detection device at the water receiving disc 32 is obtained, if the water level detection signal is greater than or equal to a preset value, the water pump is turned on and the water level control valve 24 is turned off, so that water is supplied by the water receiving disc 32, and if the water level detection signal is less than the preset value, the water level control valve 24 is turned on at a preset opening degree to supply water by the water storage tank 31.
In the cleaning mode, the ultrasonic oscillator 22 is controlled to stop, the water pump is turned on, the water level control valve 24 is turned on, and the cross-flow fan blade 1 is controlled to rotate at a second lower rotation speed. Because the water consumption for spraying and cleaning the heat exchanger 81 is large, the water needs to be supplied from the water storage tank 31; turning on the water pump to provide a higher water pressure; in addition, the rotation speed of the cross-flow fan blade 1 is reduced so that the water column can more sufficiently spray the surface of the heat exchanger 81.
In addition, the air conditioner further includes a drain pipe 72, and the water pipe 71 may be pulled out from the joint of the water pan 32 before cleaning the heat exchanger 81, and the drain pipe 72 is attached to the water pan 32, so that dirty water falling down to the water pan 32 by spraying the heat exchanger 81 can be discharged through the drain pipe 72.
In addition, when the system determines that the cleaning mode has reached the preset duration, the water pump is controlled to be turned off and the water level control valve 24 is controlled to be turned off, and the heater 82 is controlled to be turned on. The heater 82 is arranged right below the cross-flow fan blade 1 and between the two heat exchangers 81 arranged in a V shape, so that after spray cleaning is completed, the heater 82 is started to evaporate water to dryness on the heat exchangers 81.
In other embodiments of the air conditioner, the mist outlet pipe extends along the axial direction of the through-flow fan blade and exceeds half of the length of the through-flow fan blade, a first axial end of the mist outlet pipe is connected with the first side of the fan blade main body, and a second axial end of the mist outlet pipe is connected with the axial middle part of the fan blade main body.
In other embodiments of the air conditioner, the fan blade main body is connected to the output shaft of the driving unit, that is, the mist outlet pipe is not used as the rotation shaft of the through-flow fan blade but driven by the output shaft of the driving unit.
In other embodiments of the air conditioner, the plurality of mist outlet holes in the mist outlet pipe have equal apertures.
In other embodiments of the air conditioner, a bridge is disposed between the output end of the delivery tube and the first axial end of the mist outlet pipe.
Finally, it should be emphasized that the foregoing description is merely illustrative of the preferred embodiments of the invention, and that various changes and modifications can be made by those skilled in the art without departing from the spirit and principles of the invention, and any such modifications, equivalents, improvements, etc. are intended to be included within the scope of the invention.
