Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a wall-mounted indoor unit and an air conditioner. Background Art

[0002] At present, with the improvement of people's quality of life, the utilization rate of air conditioners is gradually increasing. Air conditioners are devices that can adjust the indoor temperature.

[0003] The air in the air conditioner flows through the heat exchanger arranged in the air conditioner and is cooled or heated. The cooled or heated air is then sent into the room through the air outlet. Therefore, the air inlet is generally arranged at the top of the air conditioner housing, and the air outlet is usually arranged at the lower part of the front side of the air conditioner housing (which can be called the "front panel"). When the air conditioner is running in cooling mode, if a person is close to the air conditioner, the cold air blown out from the air conditioner will blow directly on the person, which is easy to cause discomfort.

[0004] However, a single air guide plate assembly is generally installed on the indoor unit of a conventional wall-mounted air conditioner, and the air guide plate assembly has a poor effect in adjusting the air outlet direction, and can only adjust all air outlet airflows to one direction, which seriously affects the user's comfort. Although an external anti-direct blowing air guide plate has gradually been developed in the prior art, by placing the anti-direct blowing air guide plate at the air outlet and setting a number of small holes on the anti-direct blowing air guide plate, when the air conditioner is running in cooling mode or heating mode, the heat exchange air is dispersed when passing through the small holes of the anti-direct blowing air guide plate to prevent direct blowing, but this causes a significant decrease in the air conditioning effect, and when people are far away from the air conditioner, the air conditioner needs to be able to deliver air over a long distance.

[0005] In addition, in order to effectively alleviate the problem of direct blowing, in recent years, technicians have tried to make various improvements to the control logic and structure of the air conditioner; among them, the simplest improvement is to make corresponding improvements to the air guide structure of the indoor unit. Specifically, in addition to the small air guide plate set at the air outlet, some existing indoor units also have a largely rotatable air guide component set on the outside of the indoor unit body. The air guide component includes a connected rotating arm and an air guide plate, and the existing air guide components can only adjust the air guide posture of the air guide component by rotating the rotating arm. The adjustment method is very limited. It is difficult to effectively adapt to the ever-changing air guide needs during actual use, and the structure is extremely complex, which will result in more parts being set at the air outlet of the air conditioner, affecting the integrity and consistency of the air conditioner structure.

[0006] In addition, in current air conditioners, due to the limiting effect of the outer shell, most air guide doors can only rotate in one direction. The air outlet frame of wall-mounted indoor air conditioners mostly adjusts the air outlet direction by the opening angle of the air guide door (one-way), but this is not the best way to control the cooling and heating angles, and the comfort experience is poor.

[0094] The other structures are the same as those in Example 1.

[0095] As a preferred example of the present application, the present application also discloses an air conditioner, including a wall-mounted indoor unit as described in the above embodiment, wherein an air outlet 300 is arranged on the wall-mounted indoor unit, and the air guide door 3 of the air guide plate assembly on the wall-mounted indoor unit can be extended and rotated relative to the air outlet 300.

[0096] As a preferred example of the present application, the present application also discloses an air conditioner control method, comprising the following steps:

[0097] S1: The indoor unit 100 is turned on to determine whether to execute the direct blowing prevention function. If so, it goes to S2; if not, it goes to S4;

[0098] S2: the second drive motor 8 on the sliding arm 2 of the air guide plate assembly 200 starts to work, driving the sliding arm 2 to slide along the guide track 5 on the connecting arm 1 toward a side away from the connecting head 102 of the connecting arm 1, thereby opening the air outlet 300;

[0099] S3: Adjust the air guide angle of the air guide door 3 until the direct blowing prevention function ends, and then enter S5;

[0100] S4: the indoor unit 100 performs a normal air outlet operation, and the first driving device 4 drives the air guide door 3 to rotate relative to the sliding arm 2 to open the air outlet 300;

[0101] S5: Whether the indoor unit receives the shutdown command, if yes, go to S6, if no, go to S1;

[0105] S32: If the indoor unit 100 performs the heating operation, the first driving device 4 drives the air guide door 3 to rotate, and the lower edge of the air guide door 3 rotates downward by β, so that the air outlet 300 is guided by the air guide door 3 and then discharges air upward.

[0106] In step S2, the air guide door 3 opens the air outlet 300 under the action of the sliding arm 2 and faces the air outlet 300. The value range of α and β is 5° to 30°.

[0107] As a preferred example of the present application, in step S4, under the cooling condition, five adjustable wind speed gears are included, namely strong, high, medium, low, and silent. The air intake of the five adjustable wind speed gears decreases in sequence. As the air volume decreases, the air outlet angle of the air guide door 3 gradually increases, and the opening angle of the air guide door 3 gradually decreases. As an example of the present application, under the cooling condition, the air guide door 3 rotates at the first rotating shaft, and the opening angle of the air guide door 3 is A, where:

[0108] The air outlet of the air conditioner is adjusted to a strong wind level, A = γ;

[0117] The air outlet of the air conditioner is adjusted to the medium wind speed, B = 0.6δ;

[0118] The air outlet of the air conditioner is adjusted to a low wind speed, B = 0.4δ;

[0119] The air outlet of the air conditioner is adjusted to a silent wind speed, B=0.2δ.

[0120] This setting reduces the air volume and presses the air outlet angle downward under heating conditions, so that the hot air blows downward, which is more conducive to regulating the ambient temperature.

[0121] As a preferred example of the present application, in step S6, the following steps are included:

[0122] S61: Control the first driving device 4 to drive the air guide door 3 to rotate to a position facing the air outlet 300;

[0123] S62: Determine whether the sliding arm 2 is in the open state, if so, proceed to S63, if not, proceed to S64;

[0125] S64: The air guide door 3 covers the air outlet 300 and the machine is turned off.

[0126] The air conditioner control method described in the present application optimizes the control program of the air guide door 3 on the basis of the improvement of the structure of the air guide plate assembly of the wall-mounted air conditioner indoor unit described in the above embodiment, and adjusts the air guide angle according to the working state (cooling or heating), thereby improving the efficiency of air flow, improving the performance of the air conditioner, and providing more air outlet conditions, so that users can obtain a more comfortable and uniform air distribution environment, thereby enhancing the user experience.
