The invention provides a wall-mounted air conditioner indoor unit.
In the embodiment of the present invention, referring to fig. 1 and fig. 2, the wall-mounted air conditioning indoor unit includes a casing 10, an air deflector 14, and a baffle 30, wherein a first air inlet 11 is disposed above the casing 10, and an air outlet 12 is disposed below the casing 10. The air deflector 14 is rotatably installed at the air outlet 12 for guiding air up and down. The baffle 30 is rotatably mounted to the housing 10, a rotary connection of the baffle 30 is located between the air outlet 12 and the first air inlet 11, and a rotation axis of the baffle 30 is along a length direction of the housing 10 so as to be capable of rotating towards the air outlet 12.
In this embodiment, the wall-mounted air conditioning indoor unit is long, that is, the casing 10 is long, and the first air inlet 11 and the first air outlet 12 both extend along the length direction of the casing 10 and are long. The air deflector 14 extends along the length direction of the air outlet 12, and the rotation axis of the air deflector 14 is along the length direction of the casing 10, so that when the air deflector 14 is rotated, the air can be guided up and down at the air outlet 12.
The baffle 30 is rotatably mounted on the front side of the housing 10, for example, the rotational connection position of the baffle 30 is located at the upper edge of the air outlet 12, and when the baffle 30 rotates downward, the baffle can approach the air outlet 12 or rotate to the air outlet path of the air outlet 12 (the air outlet path of the air outlet 12 refers to the area swept by the air outlet flow in the up-down direction when the air deflector 14 is guiding air), so as to cooperate with the air deflector 14 to supply air. For example, when the wall-mounted air conditioning indoor unit is in a cooling condition (see fig. 3), the air deflector 14 may be inclined upward, so that the outlet airflow is blown out obliquely upward. At this moment, the baffle 30 can be rotated to the extending direction along the upper side wall of the air outlet duct, or the extending direction of the upper side wall of the air outlet duct is inclined upwards by a certain angle, so that the baffle 30 is matched with the air deflector 14, which is equivalent to the extension of the air outlet duct, is favorable for extending the diffusion section of the air outlet 12, and can increase the air outlet pressure, thereby realizing remote air supply. And in the refrigeration working condition, the air deflector 14 and the baffle 30 can be rotated to be in a downward inclined state, so that short-distance air supply is realized, and cold air flow is directly blown to a position or a human body with a rapid cooling requirement. Namely, the relative position between the baffle 30 and the air deflector 14 is adjusted, which is equivalent to adjusting the size of the air outlet 12, so that the air outlet pressure can be adjusted, and the air supply distance can be adjusted.
When the wall-mounted air conditioning indoor unit is in a heating condition (see fig. 4), the air deflector 14 may be rotated to a downward-inclined state to blow out the hot air downward, and at this time, the baffle 30 may be further rotated downward toward the air outlet 12. For example, the limit position of the baffle 30 that is opened by rotating is set on the air outlet path of the air outlet 12, so that the baffle 30 can rotate to a state of being inclined downward and being located on the air outlet path of the air outlet 12, so as to block the hot air from being directly sent forward, and press the air outlet flow downward, so that the hot air is better blown out downward. Therefore, the baffle 30 is matched with the air guide plate 14 to press air, so that hot air can fall to the ground to a large degree, and the hot air foot warming function can be realized more easily. In addition, in the heating working condition, the air deflector 14 and the baffle 30 can be rotated to the position with the requirement of rapid heating or the state of extending towards the human body, so that the hot air flow is directly blown to the position with the requirement of rapid heating or the human body at a far distance.
In the technical scheme of the invention, the rotatable baffle 30 is arranged on the shell 10, and the rotary connection position of the baffle 30 is arranged between the air outlet 12 and the first air inlet 11, so that the baffle 30 can rotate towards the air outlet 12, and the baffle 30 and the air deflector 14 can be matched for air supply. For example, the air deflector 14 is rotated to an upward inclined state, so that when the air outlet flow is blown out obliquely upward, the baffle 30 can be rotated to a horizontal or upward inclined state to match with the air deflector 14 for air outlet, which is equivalent to extending the air outlet duct, is beneficial to extending the diffuser section of the air outlet 12, and can increase the air outlet pressure, thereby realizing remote air supply. And rotate the aviation baffle 14 to the state of inclining downwards for when the air-out air current blows out downwards, can also rotate the baffle 30 to air outlet 12 department downwards this moment, make the baffle 30 rotate to the state of inclining downwards to stop the air-out air current to send out forward, and push down the air-out air current, make the air-out air current blow out downwards better, thereby realize closely supplying air. Compared with the mode of only adjusting the air supply distance through the air guide plate 14, the air supply distance adjusting device has the advantages that the baffle 30 and the air guide plate 14 are arranged to cooperate for air supply, the air supply distance adjusting capacity of the indoor unit of the wall-mounted air conditioner can be improved, the air supply distance can be adjusted more conveniently, accordingly, far and near air supply can be better achieved, 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 plate bodies 31, the plurality of plate bodies 31 are distributed along a length direction of the housing 10, and each plate body 31 is independently rotatably mounted to the housing 10. Specifically, the rotation axes of the plurality of plate bodies 31 are all along the length direction of the casing 10, so that the air outlet 12 can supply air in multiple directions by adjusting the relative positions of the plurality of plate bodies 31 and the air guide plate 14. For example, under the cooling condition, when the user needs to cool down locally and rapidly, the partial plate 31 may be inclined or horizontal downward, so that the cool air is blown directly to the position to be cooled or the human body. Meanwhile, the other part of the plate body 31 can be inclined upwards to realize long-distance air supply and indoor integral cooling. Similarly, in the heating condition, when the user needs to warm up the temperature locally and quickly, the partial plate 31 may be rotated to the position to be warmed up or the extended state of the human body, so that the hot air is directly blown to the position to be warmed up or the human body, and meanwhile, the other partial plate 31 may be tilted downward to realize the foot warming function. Of course, in other embodiments, the baffle 30 may be unitary plate-shaped.
Referring to fig. 1, in an embodiment, a louver 40 is disposed on the air guiding surface of the air guiding plate 14, and the louver 40 is rotatably connected to the air guiding plate 14. Specifically, the rotation axis of the louver 40 is substantially perpendicular to the length direction of the outlet 12, so that when the air deflector 14 rotates to guide the outlet airflow to flow up and down, the louver 40 rotates relative to the outlet surface of the air deflector 14 to guide the airflow to flow left and right, and the outlet airflow is rapidly and stably delivered to each region 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 guide surface of the air guide plate 14 is provided with an axle hole, the louver 40 comprises an air guide part and a rotating shaft fixedly connected with the air guide part, and the rotating shaft is arranged in the axle hole. In addition, in other embodiments, the louver 40 may be rotatably mounted to the housing 10.
In order to improve the air guiding efficiency of the louver 40, in an embodiment, the number of the louver 40 is multiple, the multiple louvers 40 are arranged along the length direction of the air guiding plate 14, and the wall-mounted air conditioning indoor unit further includes a link (not shown) for linking the multiple 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 all connected with the air guiding plate 14 through a rotating shaft, and a connecting rod is arranged on the same side of the plurality of louvers 40 and connected with the plurality of louvers 40, so that the connecting rod can move to drive all the louvers 40 to swing at the same time. The connection manner of the louver 40 and the connecting rod is various, such as hinged connection, fixed connection, etc. Through the arrangement of the connecting rods, the swing efficiency of the louver 40 is improved, and therefore the air guide efficiency is improved.
In one embodiment, the air guiding plate 14 has opposite front and rear sides, and the pivotal connection of the air guiding plate 14 is disposed adjacent to the rear side. Therefore, the air deflector 14 is rotatably connected, so that when the air deflector 14 is rotated and opened, the front side edge of the air deflector 14 extends out of the air outlet 12 for a longer distance, which is equivalent to prolonging the air duct, and is beneficial to increasing the air supply distance. When the louver 40 is arranged on the air deflector 14, the louver 40 can extend out of the air outlet 12, so that the situation that the part of the shell 10 at the edge of the air outlet 12 blocks air flow can be reduced when the louver 40 conducts air left and right, the air guiding range of the louver 40 is wider, the outlet air flow can be rapidly conveyed to each area of a room, and the air supply efficiency of the wall-mounted air conditioner indoor unit is greatly improved.
Referring to fig. 1 and 2, in an embodiment, the wall-mounted air conditioning indoor unit further includes an outer partition 50, the outer partition 50 is connected to the leeward side of the air guiding plate 14, and at least a portion of the outer partition 50 is spaced from the air guiding plate 14. Specifically, the outer partition 50 is an arc-shaped plate and extends along the length direction of the air guiding plate 14, and a cavity is formed between the outer partition 50 and the air guiding plate 14. After the wall-mounted air conditioning indoor unit finishes working, the outer partition plate 50 can cover the air outlet 12, and the air deflector 14 is located in the casing 10. The outer partition plate 50 is at least partially arranged at intervals with the air deflector 14, so that the condensation of the outer partition plate 50 can be reduced, and the connecting rod can be arranged in the cavity to avoid the exposure of the connecting rod. When the outer partition plate 50 is set to be an arc-shaped plate, a cavity can be formed between the outer partition plate 50 and the air guide plate 14, the outer partition plate 50 can be made to adapt to the outer surface of the shell 10, the outer surface of the shell 10 is smooth, edges and corners can be reduced, and the whole machine is attractive. Of course, in other embodiments, the outer partition 50 may be a flat plate. In addition, in other embodiments, the outer partition 50 may not be provided.
Referring to fig. 1 and 2, the wall-mounted air conditioning indoor unit further includes a heat exchanger 20 disposed in the casing 10, the casing 10 further includes a front panel 13, and the front panel 13 and the heat exchanger 20 are spaced apart to form an air intake gap 15. In order to increase the air intake of the wall-mounted air conditioning indoor unit, in an embodiment, the front panel 13 is provided with a second air inlet 131 communicated with the air inlet gap 15, a rotary 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 housing 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 a 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 airflow enters the air duct from the first air inlet 11, the airflow passes through the heat exchanger 20 to exchange heat, and then is blown out from the air outlet 12. Wherein part of the air flow can flow from the air intake 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. After the second air inlet 131 is formed in the second panel, the air flow can flow from the second air inlet 131 to the air inlet gap 15, so as to enter the heat exchanger 20 for heat exchange. The structure of the housing 10 has various structures, 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 the chassis, the face frame and the front panel 13 enclose to form an air duct. In other embodiments, the housing 10 may have other configurations.
Through set up second air intake 131 on front panel 13, can be through first air intake 11 and second air intake 131 simultaneous air inlet like this, 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 heat exchange efficiency of heat exchanger 20 and the complete machine efficiency of wall-hanging air conditioner indoor set. Furthermore, when only the first air inlet 11 is provided on the housing 10, the air inlet gap 15 is usually required to be larger to ensure that more air flows 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 conditioning indoor unit. And through set up second air intake 131 on front panel 13 for the air current that gets into from second air intake 131 can directly get into air inlet clearance 15, can guarantee that the intake of heat exchanger 20 front side is comparatively enough, thereby can set up air inlet clearance 15 less, is favorable to reducing wall-hanging air conditioner indoor set's complete machine thickness.
