The invention provides a wall-mounted air conditioner indoor unit.
In the embodiment of the present invention, referring to fig. 1 and 2, the wall-mounted indoor unit of an air conditioner includes a housing 10, an air deflector 14 and a baffle 30, a first air inlet 11 is disposed above the housing 10, and an air outlet 12 is disposed below the housing 10. The wind deflector 14 is rotatably installed at the air outlet 12 for guiding wind up and down. The baffle 30 is rotatably mounted on the housing 10, and a rotational connection portion of the baffle 30 is located between the air outlet 12 and the first air inlet 11, and a rotational axis of the baffle 30 is along a length direction of the housing 10 so as to be capable of rotating toward the air outlet 12.
In this embodiment, the wall-mounted air conditioner indoor unit is in a strip shape, that is, the casing 10 is in a strip shape, and the first air inlet 11 and the air outlet 12 extend in a strip shape along the length direction of the casing 10. The air deflector 14 extends along the length direction of the air outlet 12, and the rotation axis of the air deflector 14 extends along the length direction of the casing 10, so that when the air deflector 14 is rotated, vertical air guiding at the air outlet 12 can be realized.
The baffle 30 is rotatably mounted on the front side of the housing 10, for example, a rotational connection portion of the baffle 30 is located at an upper side edge of the air outlet 12, and when the baffle 30 rotates downward, the baffle 30 can approach the air outlet 12 or rotate on an air outlet path of the air outlet 12 (the air outlet path of the air outlet 12 refers to an area swept by an air outlet airflow along an up-down direction when the air guide plate 14 guides air), so as to be capable of being matched with the air guide plate 14 to supply air. For example, in a cooling condition (refer to fig. 3), the air deflector 14 may be inclined upward, so that the air outlet flow blows out obliquely upward. At this time, the baffle 30 can be rotated to the extending direction along the upper side wall of the air outlet air duct, or be inclined upwards by a certain angle in comparison with the extending direction of the upper side wall of the air outlet air duct, so that the baffle 30 is matched with the air deflector 14, which is equivalent to prolonging the air outlet air duct, being beneficial to prolonging the diffusion section of the air outlet 12, and increasing the air outlet pressure, thereby realizing remote air supply. And during the refrigeration working condition, the air deflector 14 and the baffle 30 can be rotated to a downward inclined state, so that close-range air supply is realized, and the cold air flow directly blows to the position or the human body with the rapid cooling requirement. That is, by adjusting the relative position between the baffle plate 30 and the air guide plate 14, the size of the air outlet 12 can be adjusted, and the air outlet pressure can be adjusted, thereby adjusting the air supply distance.
When the indoor unit of the wall-mounted air conditioner is in the heating condition (refer to fig. 4), the air deflector 14 can be rotated to a downward inclined state to blow the hot air flow downward, and the baffle 30 can be rotated downward toward the air outlet 12. For example, the limit position of the baffle 30 which is opened by rotation is set on the air outlet path of the air outlet 12, so that the baffle 30 can be rotated to be inclined downwards and located on the air outlet path of the air outlet 12, thereby preventing the hot air from being directly sent forwards, and the air outlet air is downwards pressed, so that the hot air is blown downwards better. The baffle 30 is matched with the air deflector 14 to press air, so that hot air can fall to the ground to a large extent, and the hot air foot warming function can be realized more easily. And during heating working conditions, the air deflector 14 and the baffle 30 can be rotated to a state of extending towards a position or a human body with a rapid heating requirement, so that the hot air flow directly blows to a position or a human body with the rapid heating requirement at a far distance.
In the technical scheme of the invention, the rotatable baffle plate 30 is arranged on the shell 10, and the rotating connection part of the baffle plate 30 is arranged between the air outlet 12 and the first air inlet 11, so that the baffle plate 30 can rotate towards the air outlet 12, and the baffle plate 30 can be matched with the air deflector 14 for air supply. For example, when the air deflector 14 rotates to an upward inclined state and the air outlet air flows are blown out obliquely upward, the baffle 30 can be rotated to a horizontal or upward inclined state to match with the air outlet of the air deflector 14, so that the air outlet air duct is prolonged, the diffusion section of the air outlet 12 is prolonged, the air outlet pressure can be increased, and long-distance air supply is realized. The air deflector 14 is rotated to a downward inclined state, so that when the air outlet airflow blows downwards, the baffle 30 can be rotated downwards to the air outlet 12, so that the baffle 30 is rotated to a downward inclined state to prevent the air outlet airflow from being sent forwards, and the air outlet airflow is pressed downwards, so that the air outlet airflow is blown downwards better, and close-range air supply is realized. Compared with the mode of adjusting the air supply distance through the air deflector 14, the air supply distance adjusting device has the advantages that the air supply distance adjusting device is matched with the air deflector 14 to supply air through the baffle 30, the air supply distance adjusting capability of the wall-mounted air conditioner indoor unit can be improved, the air supply distance is more conveniently adjusted, accordingly, far and near air supply can be better realized, and the use comfort of a user is improved.
Referring to fig. 1 and 3, in an embodiment, the baffle 30 includes a plurality of plates 31, the plurality of plates 31 are distributed along the length direction of the housing 10, and each plate 31 is independently rotatably mounted on the housing 10. Specifically, the rotation axes of the plurality of plates 31 are all along the length direction of the casing 10, so that the air outlet 12 can supply air in a plurality of directions by adjusting the relative positions of the plurality of plates 31 and the air deflector 14. For example, under the cooling condition, when the user needs to locally and rapidly cool, part of the plate body 31 can be inclined downwards or horizontally, so that the cold air directly blows to the position to be cooled or the human body. And meanwhile, other part of the plate body 31 can be inclined upwards, so that long-distance air supply and indoor integral cooling are realized. Similarly, under the heating working condition, when the user needs to locally and rapidly heat, part of the plate body 31 can be rotated to a state extending towards the position to be heated or the human body, so that hot air directly blows the position to be heated or the human body, and meanwhile, other part of the plate body 31 can be inclined downwards, so that the foot warming function is realized. Of course, in other embodiments, the baffle 30 may be in the form of an overall plate.
Referring to fig. 1, in an embodiment, a louver 40 is disposed on an air guiding surface of the air guiding plate 14, and the louver 40 is rotatably connected with the air guiding plate 14. Specifically, the rotation axis of the louver 40 is approximately perpendicular to the length direction of the air outlet 12, so that when the air deflector 14 rotates to guide the air-out airflow to flow up and down, the louver 40 rotates relative to the air-out surface of the air deflector 14 to guide the air-out airflow to flow left and right, so that the air-out airflow is quickly and stably conveyed to each area of the room. Namely, the air guide plate 14 and the louver 40 are coupled to supply air, so that the air supply efficiency of the wall-mounted air conditioner indoor unit is greatly improved. In order to make the air supply of the louver 40 more accurate and stable, the air guiding surface of the air guiding plate 14 is provided with a shaft hole, the louver 40 comprises an air guiding part and a rotating shaft fixedly connected with the air guiding part, and the rotating shaft is arranged in the shaft hole. In addition, in other embodiments, the louvers 40 may also be rotatably mounted to the housing 10.
In order to improve the air guiding efficiency of the louvers 40, in one embodiment, the number of louvers 40 is plural, the louvers 40 are arranged along the length direction of the air guiding plate 14, and the wall-mounted indoor unit of the air conditioner further includes a connecting rod (not shown) for linking the louvers 40. Specifically, the plurality of louvers 40 are uniformly distributed on the air guiding surface of the air guiding plate 14, the plurality of louvers 40 are connected with the air guiding plate 14 through a rotating shaft, a connecting rod is arranged on the same side of the plurality of louvers 40, and the connecting rod is connected with the plurality of louvers 40, so that the movement of the connecting rod can drive all the louvers 40 to swing at the same time. The shutter 40 and the connecting rod can be connected in a plurality of ways, such as hinging, fixed connection and the like. By the arrangement of the connecting rods, the swinging efficiency of the louver 40 is improved, and therefore the air guiding efficiency is improved.
In one embodiment, the air deflection 14 has opposite front and rear sides, and the rotational connection of the air deflection 14 is located adjacent the rear side. The air guide plates 14 are rotatably connected, so that when the air guide plates 14 are rotatably opened, the front side edges of the air guide plates 14 extend out of the air outlet 12 far, which is equivalent to prolonging the air duct and is beneficial to improving the air supply distance. And when setting up tripe 40 on aviation baffle 14, can make tripe 40 stretch out outside the air outlet 12 to when tripe 40 is controlled the wind-guiding, can reduce the casing 10 part at air outlet 12 edge and block the condition of air current, make the wind-guiding scope of tripe 40 wider, thereby make the air-out air current can be quick carry to each region in room, improved wall-mounted air conditioner indoor set's air supply efficiency by a wide margin.
Referring to fig. 1 and 2, in an embodiment, the wall-mounted indoor unit of an air conditioner further includes an outer partition 50, the outer partition 50 is connected to the leeward side of the air deflector 14, and at least a portion of the outer partition 50 is spaced from the air deflector 14. Specifically, the outer separator 50 is an arc-shaped plate, extends along the longitudinal direction of the air guide plate 14, and forms a cavity between the outer separator 50 and the air guide plate 14. When the wall-mounted air conditioner indoor unit is finished, the outer partition plate 50 can cover the air outlet 12, and the air deflector 14 is positioned in the shell 10. By disposing the outer separator 50 at least partially spaced from the air deflection 14, condensation of the outer separator 50 can be reduced, and the tie rod can be disposed within the cavity to avoid exposure of the tie rod. When the outer baffle 50 is arranged to be an arc plate, a cavity can be formed between the outer baffle 50 and the air deflector 14, the outer baffle 50 can be adapted to the outer surface of the shell 10, the outer surface of the shell 10 is smooth, the existence of edges and corners can be reduced, and the whole machine is attractive. Of course, in other embodiments, the outer baffle 50 may also be in the form of a flat plate. In addition, in other embodiments, the outer separator 50 may not be provided.
Referring to fig. 1 and 2, the wall-mounted air conditioner indoor unit further includes a heat exchanger 20 disposed in the housing 10, the housing 10 further includes a front panel 13, and the front panel 13 is spaced from the heat exchanger 20 to form an air intake gap 15. In order to increase the air intake of the indoor unit of the wall-mounted air conditioner, in an embodiment, the front panel 13 is provided with a second air inlet 131 communicated with the air intake gap 15, the rotation connection position of the baffle 30 is located between the air outlet 12 and the second air inlet 131, and the baffle 30 can cover the second air inlet 131. Specifically, the casing 10 has an air duct, a fan is disposed in the air duct, and the heat exchanger 20 is disposed in the air duct and enclosed on a side of the fan facing the first air inlet 11. An air inlet gap 15 is formed between the front side of the heat exchanger 20 and the front panel 13, i.e. the air inlet gap 15 is part of the air duct. The first air inlet 11 is communicated with the air duct and is positioned above the heat exchanger 20, and the air outlet 12 is communicated with the air duct and is positioned below the heat exchanger 20. When the air flow enters the air duct from the first air inlet 11, the air flow is blown out from the air outlet 12 after heat exchange through the heat exchanger 20. Wherein a portion of the air flow is able to flow from the air inlet gap 15 to the front side of the heat exchanger 20 to enter the heat exchanger 20 from the front side of the heat exchanger 20. And after the second air inlet 131 is arranged on the second panel, air flow can flow from the second air inlet 131 to the air inlet gap 15, so that the air enters the heat exchanger 20 for heat exchange. The structure of the housing 10 is various, for example, in this embodiment, the housing 10 includes a chassis and a face frame connected to the chassis, the front panel 13 is connected to the face frame, and an air channel is formed by enclosing the chassis, the face frame and the front panel 13. In other embodiments, the housing 10 may have other configurations.
Through set up second air intake 131 on front panel 13, so can be through first air intake 11 and second air intake 131 simultaneous air inlet, increased the air inlet area to guarantee that the intake of each position of heat exchanger 20 is all great, be favorable to improving the complete machine efficiency of heat exchange efficiency and the wall-hanging air conditioner indoor set of heat exchanger 20. Moreover, when only the first air inlet 11 is provided on the housing 10, it is generally necessary to provide the air inlet gap 15 with a larger size to ensure that there is more air flow from the air inlet gap 15 to the lower end position of the front side of the heat exchanger 20. However, this increases the distance between the heat exchanger 20 and the front panel 13, i.e., increases the thickness of the wall-mounted air conditioner indoor unit.
