Description

TECHNICAL FIELD

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

[0002] At present, with the improvement of people's living quality, the use rate of air conditioners is also gradually increasing. The air conditioner is a device capable of adjusting the indoor environment temperature.

[0003] Air flows over a heat exchanger arranged in the air conditioner to be 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 shell, and the air outlet is usually arranged at the lower part of the front side (which can be referred to as "front panel") of the air conditioner shell. When the air conditioner operates in the cooling mode, if a person is relatively close to the air conditioner, the cold wind blown from the air conditioner will directly blow on the person, which can easily cause the person to feel uncomfortable.

[0004] However, the conventional wall-mounted air conditioner indoor unit generally has a single air deflector assembly installed thereon, and the air deflector assembly has a poor effect on adjusting the air outlet direction, and can only adjust all air outlet flows to one direction, which seriously affects the user comfort. Although an external anti-direct-blow air deflector has been gradually developed in the prior art, by arranging a plurality of small holes on the anti-direct-blow air deflector at the position of the air outlet, when the heat exchange air passes through the small holes of the anti-direct-blow air deflector in the cooling mode or the heating mode, the heat exchange air is dispersed to achieve anti-direct-blow, but it causes a significant decrease in the air conditioning efficiency, and when a person is far away from the air conditioner, the air conditioner needs to be able to achieve long-distance air supply.

[0005] In addition, in order to effectively alleviate the direct-blow problem, in recent years, technical personnel have tried various improvements to the control logic and structure of the air conditioner; among them, the simplest improvement way is to make corresponding improvements to the air deflection structure of the indoor unit. Specifically, some existing indoor units have a small air deflector arranged at the air outlet, and also have an air deflection member that can be rotated greatly outside the body of the indoor unit. The air deflection member includes a connecting rotating arm and an air deflector, and the existing air deflection member can only adjust the air deflection posture of the air deflection member by rotating the rotating arm, and the adjustment mode is very limited. It is difficult to effectively adapt to the changing air deflection demand in the actual use process, and the structure is extremely complex, which can cause more components to be arranged at the air outlet of the air conditioner, affecting the overallity and consistency of the air conditioner structure.

[0006] In addition, in the current air conditioner, due to the limiting effect of the shell, most of the air deflection doors can only rotate in one direction. The air outlet frame of the wall-mounted indoor unit air conditioner is usually adjusted by the opening angle (one-way) of the air deflection door, but such cooling and heating angle control is not optimal, and the comfort experience is poor.

[0074] Embodiment 2

[0075] As Figures 1-20 shown, the present application discloses a wall-mounted indoor unit, comprising:

[0076] an air outlet 300 for the indoor unit to blow air outward;

[0077] an air guide plate assembly 200, comprising a connecting arm 1, a sliding arm 2, and an air guide door 3, the sliding arm 2 can drive the air guide door 3 to slide on the connecting arm 1, and the connecting arm 1 is used to connect the air guide plate assembly 200 to the indoor unit shell;

[0078] Among them, the connecting arm 1 is provided with two, which are respectively the first connecting arm 11 and the second connecting arm 12, and correspondingly, the sliding arm 2 is provided with two, which are respectively the first sliding arm 21 and the second sliding arm 22, the first sliding arm 21 can slide on the first connecting arm 11, the second sliding arm 22 can slide on the second connecting arm 12, a first connecting hole 702 is arranged on the first sliding arm 21 and the second sliding arm 22 correspondingly, the first connecting hole 702 is arranged in an arc shape, a first pivot limiting portion 7021 and a second pivot limiting portion 7022 are formed at opposite ends of the first connecting hole 702, and a first connecting shaft 303 and a second connecting shaft 305 at both ends of the air guide door 3 pass through the first connecting hole 702 respectively;

[0080] The third driving device 17 can drive the air guide door 3 to swing bidirectionally along the first rotation shaft limiting part 7021 or the second rotation shaft limiting part 7022 relative to the air outlet 300.

[0081] The wall-mounted indoor unit disclosed in the present application improves the structure design of the air deflector assembly 200. On the basis of the air deflector assembly 200 disclosed in Embodiment 1, which comprises a connecting arm 1 and a sliding arm 2 and can block or open the air outlet 300, the driving structure of the air guide door 3 in the air deflector assembly 200 is further improved. The first driving device 4 and the third driving device 17 are provided. The first driving device 4 is used to drive the air guide door 3 to switch positions between the first rotation shaft limiting part 7021 and the second rotation shaft limiting part 7022. The third driving device 17 is used to drive the air guide door 3 to move outward from the air outlet 300 at the first rotation shaft limiting part 7021 and the second rotation shaft limiting part 7022, respectively, to open the air outlet 300, so as to realize different rotation directions and angles of the air guide door 3 in the cooling and heating conditions. Specifically, the first rotation shaft limiting part 7021 is located above and outward of the second rotation shaft limiting part 7022, i.e., the first rotation shaft of the air guide door 3 is formed above and outward of the second rotation shaft. In the cooling condition, the first driving device 4 can drive the air guide door 3 to move to the second rotation shaft limiting part 7022. The third driving device 17 can drive the air guide door 3 to rotate along the first rotation shaft. The air guide door 3 rotates outward from the upper side, so as to realize upward air outlet of the air outlet 300 under the action of the air guide door 3 in the cooling condition. In the heating condition, the first driving device 4 can drive the air guide door 3 to move to the first rotation shaft limiting part 7021. The third driving device 17 can drive the air guide door 3 to rotate along the second rotation shaft. The air guide door 3 rotates outward from the lower side, so as to realize downward air outlet of the air outlet 300 under the action of the air guide door 3 in the heating condition. Since the air guide door 3 rotates along the two rotation shafts in the cooling and heating conditions, respectively, the air deflector can adapt to different air guide angles in the heating and cooling conditions, so as to realize double-axis positive and negative rotation air guide of the air guide mechanism in different conditions.

[0082] The wall-mounted indoor unit disclosed in the present application improves the structure of the air deflector assembly. A set of air guide doors combined with a sliding assembly are provided to realize switching of the air guide structure for preventing direct blowing. The driving structure of the air guide door is improved. In different conditions, the air guide direction cannot be switched flexibly, which leads to that the cooling and heating conditions cannot reach the best comfortable state. The air outlet condition of the indoor unit is enriched, the best temperature distribution control is provided, the air flow is better controlled and adjusted, the indoor comfort is improved, and the discomfort caused by direct blowing is reduced.
