By adopting the structure, the structure layout is compact, the structure layout is optimized, and the number of the evaporators 40 is reduced, so that the effective utilization rate of the evaporators 40 is improved.
In this embodiment, the connecting casing 30 is disposed opposite to the panel 13 of the indoor unit casing 10, one end of the evaporator 40 is mounted on the connecting casing 30, and the other end of the evaporator 40 is mounted on the panel 13, so that the evaporator 40 is disposed obliquely to the horizontal direction. By adopting the structure, the heat exchange area can be increased, the heat exchange quantity is effectively ensured, and meanwhile, the compactness of the structural layout is better improved.
The invention is characterized in that: connect the following wind through increasing the wind channel baffle in panel 13 positions, avoid producing vortex and wind channel noise, strengthen air outlet wind speed and amount of wind simultaneously, solve the problem that air conditioner internal noise problem and refrigeration speed are slow, improve the travelling comfort and experience. As shown in fig. 1, the air duct assembly of the air conditioner provided by the invention comprises an upper air inlet baffle assembly, an upper air duct volute tongue 22, an upper air duct baffle, an upper cross flow fan blade, an evaporator 40 assembly, a lower cross flow fan blade, a lower air duct baffle, a lower air duct volute tongue 22 and a lower air inlet baffle assembly. The air conditioner is installed with the center distance of 1.3m from the ground, the whole air conditioner has no air guide plate structure, only the air duct is used for controlling the air outlet direction, and the problem that the manual air guide plate is broken to directly blow the human body is greatly controlled. As shown in fig. 2 and 3, the air duct baffles are arranged at the upper and lower air ports on the side of the panel 13, and when the air duct is used for blowing air, the air duct is actively closed, otherwise, the air duct is opened, and the air inlet amount is increased.
When the novel cool function is started, as shown in fig. 3, the lower air duct baffle is closed, the upper air duct baffle is opened, the upper air inlet plays a role of air inlet at the moment, the lower air inlet is an air outlet, the air inlet amount is increased due to the fact that the upper air duct baffle is opened, the air outlet logic is performed when the air conditioner inner unit operates, the outer unit compressor operates at a high speed, and the temperature of the air outlet is reduced to the maximum extent. The lower air duct baffle is closed, so that the air speed of the air outlet is enhanced, and the vortex near the volute tongue 22 is reduced, thereby reducing the noise of the air duct and increasing the air supply distance. Due to the particularity of the wall hanging position of the air conditioner, the lower air outlet blows downwards obliquely to the ground, circulating air can be produced in a room, the temperature in the room is quickly reduced, and people feel cool.
After the air is discharged for 1 hour under the operation, the air conditioner is automatically switched to be discharged from the upper part. As shown in fig. 2, at this time, the lower duct baffle is opened, the upper duct baffle is closed, the lower air inlet is used as an air inlet, and the upper air inlet is used as an air outlet. The switching of the upper air outlet and the lower air outlet is to improve the comfort of air supply of the air conditioner, and shower type air supply can enable people to feel natural transition from environment heat to cool, reduce discomfort caused by rapid reduction of the body temperature of a human body, and reduce the risk of suffering from air conditioning diseases. The air duct baffle is arranged at the position of the volute tongue 22, and the changeable volute tongue 22 performs corresponding actions when switching between an upper air inlet and a lower air inlet to solve the problem of noise of the air duct of the air conditioner and improve the air volume. When the cool feeling function is started, the time of the lower air outlet can be any time within 1 min-2H, and then the upper air outlet is switched to refrigerate.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: the problem that the air inlet amount is reduced when air outlet and air inlet are switched is solved; the problem of air duct noise caused by easy generation of air vortex near the volute tongue of the air duct is solved; the problem of air output little, people are difficult for experiencing the refrigeration of air conditioner is solved. A movable air duct shell is used, and when the air inlet and the air outlet are switched, the air duct shell is automatically opened and closed, so that the air inlet amount is increased; the panel side near the volute tongue is provided with a movable air duct baffle, when the air duct is used for blowing, the movable air duct baffle is actively closed and connected with the downwind flow, so that the generation of vortex is avoided, and the noise of the air duct is reduced; when the air duct is used as an air outlet duct, the air duct baffle at the panel is closed, and the air pressure is connected and enhanced, so that the air speed of the air outlet is larger, and the air volume is also larger; increase novel cool sense function, when opening, the air conditioner carries out the air-out refrigeration under the power, because the advantage of wind channel and mounted position, can make the circulated air in the room, the refrigeration does not blow the people, lets the people feel cool rapidly.
