Detailed Description
The air conditioner in the prior art has a single control mode of the air outlet direction, and the air outlet direction is manually adjusted by a user or the heating and the refrigerating are controlled by the same air direction. The difference between the cold air temperature and the human body temperature is usually larger, so that it is not suitable for direct blowing. The air conditioner in the prior art therefore often has the following problems:
1) the air outlet direction of the air conditioner cannot be automatically adjusted according to the refrigeration or heating working condition, so that the comfort level is reduced by directly blowing the human body with the same direction during the refrigeration under the condition that the direct blowing comfort level of the human body is still enough during the heating;
2) due to the density relationship, cool air is easily deposited at low locations in the room, while warm air is easily deposited at high locations in the room, resulting in an insufficiently uniform room temperature and a poor air circulation in the room.
The above problems all result in a reduced comfort for the user.
In order to solve the problem that the comfort of a user of a current air conditioner is poor, the embodiment of the application provides an air conditioner and a control method thereof.

Air conditioner 010 includes casing 100, fan 200, air guide door 300, first driving piece 310 and controller 500, is provided with air outlet 130 on the casing 100, and fan 200 sets up in casing 100 and communicates with air outlet 130 through wind channel 140, and air guide door 300 rotationally connects in casing 100 in air outlet 130 department, and first driving piece 310 is used for driving air guide door 300 and rotates to the air-out direction of adjustment air outlet 130. The controller 500 is used for receiving user instructions, controlling the blower 200 to start and stop, and controlling the first driving member 310 to rotate the air guide door 300. The housing 100 of the air conditioner 010 of the embodiment of the present application further includes other necessary components, such as a heat exchanging coil, related sensors, etc., which are not described herein by way of example.
The air guide door 300 of the embodiment has a first position and a second position, in the air outlet process, the included angle α between the air outlet direction and the gravity direction when the air guide door 300 is located at the first position is smaller than the included angle β between the air outlet direction and the gravity direction when the air guide door 300 is located at the second position, so that the air outlet direction at the air outlet 130 can be adjusted through the rotation of the air guide door 300.
In the present embodiment, the casing 100 includes a front side plate 110 and a lower side plate 120, the air outlet 130 has a first region 132 and a second region 134 connected to each other, the first region 132 is opened on a side of the lower side plate 120 close to the front side plate 110, and the second region 134 is opened on a side of the front side plate 110 close to the lower side plate 120. The housing 100 further includes a front panel 400 movably disposed on the front panel 110, and a second driving member 410 in transmission connection with the front panel 400, the front panel 400 is movably connected to the front panel 110, the second driving member 410 is used for driving the front panel 400 to open or close the second area 134 of the air outlet 130, and the second driving member 410 is electrically connected to the controller 500.
In the embodiment shown in fig. 1, in the cooling condition of the air conditioner 010, the air guiding door 300 is located at the second position, the air guiding door 300 blocks the first area 132, and the second area 134 is opened due to the front panel 400 moving to the open position. The air guide door 300 blocks the first area 132 and opens the second area 134, so that the air flow can only flow out of the second area 134. In this embodiment, the air guiding door 300 is disposed horizontally when in the second position, so as to better guide the air flow to be sent out horizontally to the left.
In the embodiment shown in fig. 2, under heating conditions, the damper door 300 is in the first position, the damper door 300 blocks the second region 134, and the first region 132 is open. The airflow is only sent out from the first area 132 of the air outlet 130 under the blocking action of the air guiding door 300. Because the airflow is sent out from the first area 132 under the heating condition, the airflow is sent out from the second area 134 under the cooling condition, the first area 132 faces forwards, and the second area 134 faces downwards, the air outlet direction can be raised under the cooling condition.
By providing the front panel 400, the second area 134 can be opened or closed, so that when downward wind needs to be blown out, the air flow can be better prevented from being sent out from the second area 134, and the air flow can be completely sent out from the first area 132; due to the blocking effect of the front panel 400 on the airflow, the air guiding door 300 may not block the airflow at the position of the second area 134 (as shown in fig. 5). In the cooling operation, the front panel 400 opens the second region 134, so that the air can be smoothly discharged from the second region 134.

Because the air outlet direction of the air guide door 300 is inclined downwards at the first position and inclined upwards at the second position, the air outlet direction of the air conditioner is raised when cold air is discharged compared with that when hot air is discharged. Under the condition of adopting wall-mounted indoor unit, the air conditioner 010 is hung at the high position of the wall surface, the air outlet direction is raised, cold air is easily prevented from blowing the human body directly, and the comfort level of the user is improved. And because cold air density is big, and hot air density is low, therefore hot-blast air-out direction reduces relatively, and cold wind air-out direction is raised relatively, and such air-out scheme is favorable to the circulation of indoor air current and the homogenization of indoor temperature, can improve user's use and experience.
In the embodiment of fig. 1 and 2, the controller 500 is specifically configured to: under the heating condition, the first driving member 310 is controlled to rotate the air guide door 300 to the first position, so that the air flow in the air duct 140 is sent out from the first area 132; in the cooling condition, the first driving member 310 is controlled to rotate the air guide door 300 to the second position, so that the air flow in the air duct 140 is sent out from the second area 134. In an alternative embodiment, when the air guide door 300 is located at the first position, the windward side of the air guide door 300 is inclined downward. Specifically, when the air guide door 300 is in the first position, the inclination angle between the windward side and the horizontal plane may be 50 ° to 60 °. When the air guide door 300 blocks the second area 134, the air guide door 300 is obliquely arranged, so that the air flow in the air duct 140 can be smoothly guided to the first area 132, and unsmooth air outlet or abnormal sound caused by too large wind resistance is not easy to generate. Further, the controller 500 is further configured to: under the refrigeration condition, the second driving piece 410 is controlled to drive the front panel 400 to open the second area 134; under the heating condition, the second driving element 410 is controlled to drive the front panel 400 to block the second area 134.
In other embodiments, the air guiding door 300 may block neither the first area 132 nor the second area 134 when in the second position, for example, parallel to the direction of the air flow in the wind tunnel 140, so that the air flow can be sent out from both areas, as shown in fig. 4. Make the air current comparatively smooth-going like this, windage wind is made an uproar less, compares in heating the operating mode moreover and only can follow first region 132 air supply down, and the air-out direction still is raised. In an alternative embodiment, the air guiding door 300 may not block the second area 134 in the heating state, and the second area 134 may be blocked by the front panel 400. Upon closing off the second area 134 with the front panel 400, the air guide door 300 can be moved out of the first area 132 and the second area 134 in the second position, as shown in fig. 5.
