The invention improves the comfort of the existing wall-mounted air conditioner by adopting the scheme of the single fan and the upper air duct and the lower air duct, and the air supply performance of the fan is not influenced when the upper air duct, the lower air duct and the single air duct respectively work.
1. A single-fan wall-mounted air conditioner with an upper air duct and a lower air duct is characterized in that the single-fan can meet the requirements of two working modes, namely a single air duct and a double air duct.
2. An upper and lower air duct wall-mounted air conditioner can realize that the air supply performance is not influenced under the working state of a single air duct.
3. A motion mechanism capable of realizing switching of working modes of an upper air channel and a lower air channel can meet the requirement of switching of three modes of a single upper air channel, a single lower air channel and the simultaneous working of the upper air channel and the lower air channel, and the air supply range is expanded.
4. A switching plate consisting of a flexible part, a rigid part and a second heat-insulating part (preferably a heat-insulating layer) realizes air duct switching and air flow sealing.
The invention realizes the switching between the double air channels and the single air channel by pushing the air deflector mechanism, the conversion plate (namely the switching mechanism) and the second air deflector, and realizes two air supply modes of single-fan double air channel air supply and single air channel air supply. The specific implementation is as follows:
1. the whole layout of the air conditioner is as shown in figure 1, the push-out mechanism is composed of a push-out connecting rod, a first air deflector and an air deflector rotating motor, a second air deflector is arranged on the panel body and can rotate around the panel body or arranged on the flow guide wall and can rotate around the flow guide wall, and a rotating plate (namely a switching mechanism) is arranged on the bottom shell.
2. Fig. 2 shows a single upper air outlet mode, in which the second air guide plate is opened, the first air guide plate is closed, and the switching plate is rotated to a position attached to the wall surface of the bottom case. In this state, the air flow is sent out by the second air outlet after passing through the fan and the upper air duct, so that the upper air supply is realized.
3. Fig. 3 shows a single lower air outlet mode. The first air guiding plate moves from the original position to the position shown in fig. 3 under the driving of the pushing-out connecting rod, and the original position is defined as the position where the first air guiding plate closes the first air outlet. The push-out connecting rod is provided with gear teeth meshed with the driving gear. The switching plate rotates from the original position to the position shown in fig. 3 to prevent the airflow from flowing to the upper air duct. Simultaneously, the second air deflector is closed.
4. As shown in fig. 4, the air outlet mode is up and down. The connecting rod and the air guide plate rotating motor are pushed out to enable the first air guide plate to move to a heating mode position, namely the first air guide plate rotates to a position for opening the first air outlet, the second air guide plate is closed, and the switching plate is switched to the position shown in the figure 4, so that air flow is prevented from flowing from the fan to the upper air channel.
5. The rotating plate structure is shown in fig. 5 and comprises a flexible part, a rigid part, a second heat preservation part and a rotating shaft. The flexible part is used for being attached to the upper air duct to achieve air flow sealing.
Fig. 2 shows a single upward air-out mode, in which the push-out air guide plate is in a closed position, the rotating air guide plate is opened, and the angle of the rotating air guide plate can be driven and controlled by the rotating air guide plate motor. The switching plate is in a default position, and the upper air duct cavity is in an open state at the moment. After the airflow flows out from the single fan, the lower air outlet is blocked because the air deflector is pushed out to be closed, and meanwhile, the upper air duct cavity and the rotating air deflector are in an open state, so that the airflow can only flow out from the upper air outlet, and single upper air outlet is realized. The refrigeration operating mode of singly going up the air-out can avoid cold wind to blow people's head, increases cold wind simultaneously and blows the distance, improves user's comfort level.
Fig. 3 shows a single lower air outlet mode, which can realize the air outlet function of the conventional on-hook. In the mode, the air guide plate is pushed out to be opened, and a user can set the position of the air guide plate according to the requirement. The switching plate rotates to enable the flexible part of the switching plate to be in contact with the lower edge of the front panel heat insulation layer, so that the upper air duct cavity is sealed, and meanwhile, the switching plate becomes a part of the lower air outlet duct and is used for guiding air outlet flow. The rotary air deflector is in a closed state.
Fig. 4 is an up-down air-out mode, in which the air deflector is pushed out to be opened, and a user can set the position of the air deflector according to the requirement. The switching plate is in an initial default position, so that the upper air duct cavity is opened. The rotary air deflector is in an opening state. The air outlet mode can increase the air supply range in the height direction of the air conditioner, the air flow is layered and more uniform when falling to the ground, as shown in figures 13-14, the air blowing sense and the temperature distribution are more uniform, the comfort level is higher, and meanwhile, the heat exchange efficiency of a room is improved.
The principle of the invention is as follows:
1. the air supply range is expanded by simultaneously supplying air through the upper air duct and the lower air duct;
2. in order to prevent cold wind from blowing people during refrigeration, the effect that cold wind can not blow people and can blow far cold wind energy is realized by only opening the upper air inlet so as to improve the height of horizontal air supply;
3. the effect that the air supply performance of the fan is not influenced is realized by the matching of the single air duct, the upper air duct and the lower air duct and the fan through the switching mechanism.
