Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to a wall-mounted air-conditioning air guide plate assembly, an air conditioner and a control method. 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. Summary of the invention

[0006] In view of this, the present invention aims to provide a wall-mounted air-conditioning air guide plate assembly, an air conditioner and a control method to solve at least one of the above-mentioned technical problems.

[0052] The air guide door 3 is installed on the sliding arm 2 and can move integrally with the sliding arm 2 .

[0053] The present application discloses an air guide plate assembly 200, which is formed by setting an air guide door 3 and a connecting arm 1 and a sliding arm 2 to block or open an air outlet 300. When the indoor unit 100 is in a shutdown state, the air guide door 3 covers the air outlet 300 on the indoor unit 100 to achieve the air outlet 300 closing function; when the anti-direct blowing function is performed, the air guide door 3 is driven by the sliding arm 2 to slide on the connecting arm 1, so that the air guide door 3 opens the air outlet 300 on the indoor unit 100, and guides the heat exchange air blown out of the air outlet 300 on the indoor unit 100 to prevent direct blowing. By setting an air guide door, the switching of the air outlet 300 closing, anti-direct blowing and other functions can be achieved, and the air outlet 300 can be reliably covered in the shutdown state to ensure the overall integrity of the indoor unit.

[0054] The air guide plate assembly of the wall-mounted air-conditioning indoor unit described in the present application has a compact structure and smooth switching between different functions. It can more accurately control the air outlet status of the air-conditioning indoor unit and improve the adjustment of the air outlet direction. When the anti-direct blowing function needs to be executed, the sliding arm drives the air guide door to slide to open the air outlet and guide the heat exchange air blown out of the air outlet to prevent direct blowing, thereby reducing the direct blowing effect and improving the user's comfort and air-conditioning performance.

[0055] As a preferred example of the present application, a first driving device 4 is provided on the sliding arm 2, and the first driving device 4 is used to drive the air guide door 3 to rotate on the sliding arm 2.

Preferably, the connecting head 102 is fixed to the end cover of the indoor unit 100 by snapping, and the connecting arm 1 can be arranged on the inner side or the outer side of the end cover of the indoor unit 100. As a specific example, the connecting arm 1 is arranged on the outer side of the end cover of the indoor unit 100, and the outer wall of the connecting head 102 away from the end cover of the indoor unit 100 is flush with the outer wall of the first connecting plate body 101 away from the end cover of the indoor unit 100.

This setting ensures the accuracy and reliability of the position adjustment of the air guide plate, guides the air flow to the required area more accurately, provides better ventilation and air conditioning effects, and further improves the user's indoor air quality and comfort.

[0063] As a preferred example of the present application, the air guide door 3 includes an air guide plate body 301, and a first end plate 302 and a second end plate 304 are respectively arranged at the opposite ends of the air guide plate body 301, a first connecting shaft 303 is arranged on the first end plate 302, and a second connecting shaft 305 is arranged on the second end plate 304, one of the first connecting shaft 303 and the second connecting shaft 305 is connected to the first driving device 4, and the other is hinged to the bearing seat 10. As a preferred example of the present application, the air guide door connection part 7 includes a second connection plate body 701, a first connection hole 702 is set on the second connection plate body 701, the second connection shaft 305 passes through the first connection hole 702 on one of the second connection plate bodies 701 to connect with the first drive device 4, the first drive device 4 is provided with one, the sliding arm 2 of the first drive device 4 is set as the active sliding arm, and the other is the driven sliding arm, the first connection shaft 303 passes through the first connection hole 702 on the second connection plate body 701 on the driven sliding arm to connect with the bearing seat 10, and the bearing seat 10 is set on the driven sliding arm. As an example of the present application, the first drive device 4 is set on the side of the indoor unit 100 where the electric control device is set, so as to reduce the line setting.
