As shown in fig. 1 to 4, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10, a first air guide plate 51, and a second air guide plate 52.

The lower part of the front wall 13 and the front part of the bottom wall 14 of the housing 10 constitute ventilated air dispersing walls 131, 141, respectively, the air dispersing walls 131, 141 having a structure of openings, apertures or the like so as to allow air flow therethrough. The front wall 13 and the bottom wall 14 of the housing 10 are both outer walls of the housing 10, specifically a forward portion and a downward portion of the outer walls of the housing 10. The air dispersing wall 131 is a portion of the front wall 13 of the housing 10 (i.e., section AB of the front wall 13), and the air dispersing wall 141 is a portion of the bottom wall 14 of the housing 10 (i.e., section BC of the bottom wall 14).

The housing 10 defines an air duct 15. Specifically, the duct 15 is surrounded by a plurality of duct walls located in the inner space of the housing 10, and includes, for example, a front duct wall 152, a rear duct wall 151, and left and right end duct walls (not shown). The air-out flow of the air duct 15 reaches the two air-dispersing walls 131 and 141, and then penetrates through the two air-dispersing walls 131 and 141 to blow out. The outlet 150 of the air duct 15 (the area between ANs) is preferably directed towards the two air dispersing walls 131, 141 for blowing air towards them.

The first air guide plate 51 and the second air guide plate 52 are arranged in the vertical direction inside the housing 10. I.e. the first air deflector 51 is arranged above the second air deflector 52. One ends (i.e., pivot ends O1 and O2) of the first air deflector 51 and the second air deflector 52 are rotatably mounted on the housing 10, respectively, the rotation axis is parallel to the lateral direction of the housing 10, and the pivot ends (O1 and O2) of the first air deflector and the second air deflector are adjacent to the air dispersing wall 131 of the front wall 13 of the housing 10, so as to adjust the flow direction of the air outlet (i.e., adjust the included angle between the air outlet and the horizontal plane), and further adjust the air volume distribution of the two air dispersing walls 131 and 141.

For example, when the first air guide plate 51 and the second air guide plate 52 are caused to guide the air forward, the air output of the air dispersing wall 131 of the front wall 13 of the casing 10 can be made larger; when the first air deflector 51 and the second air deflector 52 are directed downward, the air output of the air dispersing wall 141 of the bottom wall 14 of the casing 10 can be made larger; when the first air guide plate 51 and the second air guide plate 52 are guided forward and downward, the air output amounts of the air release walls 131 and 141 of the front wall 13 and the bottom wall 14 of the casing 10 can be made to coincide.

In this way, the air flow from the outlet of the air duct 15 does not directly blow to the indoor environment, and must penetrate through different areas of the air dispersing walls 131 and 141 to blow in different directions, so as to achieve the effect of preventing direct blowing. And the two air dispersing walls 131 and 141 face forward and downward respectively, so that the whole air outlet angle range of the wall-mounted air conditioner indoor unit is large. And, utilize two aviation baffles to adjust the air distribution of two air-dispersing walls 131, 141 to adjust the air supply direction of casing 10, this makes wall-mounted air conditioner indoor set have diversified air supply mode, fully satisfies user's various demands.

In the embodiment of the utility model, the first air deflector 51 and the second air deflector 52 are hidden in the shell 10, and the traditional air outlet is not formed on the shell 10, so that the shell 10 is more complete and attractive in appearance, and the competitiveness in the sales market is improved. In some embodiments, the lower portion of the front wall 13 of the housing 10 and the front portion of the bottom wall 14 may be formed as an integral piece to provide a stronger overall housing 10 and a more attractive appearance.

In some embodiments, as shown in fig. 3, the housing 10 defines an accommodating space for accommodating main body components of the wall-mounted air conditioner indoor unit, including the blower fan 40, the indoor heat exchanger 30, the controller, and the like. The indoor heat exchanger 30 and the throttle device are connected with a compressor, an outdoor heat exchanger and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigeration cycle system. In the case of the heat pump type air conditioner, the indoor heat exchanger 30 functions as an evaporator in the cooling mode. In the heating mode, the indoor heat exchanger 30 functions as a condenser. The housing 10 may be provided with an air inlet 11 for introducing indoor air. Under the action of the fan 40, indoor air enters the shell 10 through the air inlet 11, forms heat exchange airflow after forced convection heat exchange with the indoor heat exchanger 30, and is guided by the air duct 15 to be blown out from the outlet 150 of the air duct 15. The housing 10 may be generally elongated in a horizontal transverse direction along a length direction, and the air inlet 11 is generally disposed at a top of the housing 10. The air duct is usually a through-flow air duct, and the fan is usually a through-flow fan.

In some embodiments, at least one of the two air dispersing walls 131, 141 may be an air outlet grille or a micro-porous plate. The air outlet grille is characterized in that a plurality of grille bars define a plurality of long or block-shaped grille holes for air outlet. The micropore plate is provided with a plurality of densely arranged micropores for air outlet. As shown in fig. 1 and 2, it is preferable that both of the air dispersing walls 131 and 141 are air outlet grilles. The at least one air-diffusing wall 131, 141 is preferably arranged to blow out the air-blown flow passing therethrough in a plurality of directions, so as to enhance the air-blown flow diffusivity and turbulence, and to enhance the natural wind effect of the air-blown flow. For example, the left side grill holes may be directed to the left and the right side grill holes may be directed to the right with respect to the air dispersing wall 131.

Further, as shown in fig. 3 and 4, the housing 10 includes a front air duct wall 152 and a rear air duct wall 151 located rearward and downward of the front air duct wall 152, the front air duct wall 152 and the rear air duct wall 151 defining the air duct 15. It will be appreciated that the two end duct walls, not shown in the figures, also define the duct 15. The outlet end of the front duct wall 152 may be brought into contact with or close to the upper end a of the air dispersing wall 131 of the front wall 13 of the housing 10, and the outlet end N of the rear duct wall 151 may be located behind the front wall 13 with a space. The outlet end N is brought into contact with the rear end of the air dispersing wall 141 of the bottom wall 14 of the casing 10, or the outlet end N of the rear duct wall 151 is spaced from the inner surface of the bottom wall 14 of the casing 10, as shown in fig. 3.

The other end of the first air deflector 51 opposite to the pivot end O1 is a free end T1. The other end of the second air deflector 52 opposite the pivot end O2 is a free end T2. In the wall-mounted air conditioning room in which the housing 10 is elongated and the longitudinal direction is parallel to the horizontal direction, the first air guide plate 51 and the second air guide plate 52 are elongated and the longitudinal direction is parallel to the horizontal direction, and the pivot ends O1, O2 and the free ends T1, T2 are both ends of the first air guide plate 51 and the second air guide plate 52 in the width direction, respectively, and can be understood as two long sides of the first air guide plate 51 and the second air guide plate 52.

The wall-mounted air conditioner indoor unit is provided with an upper air supply mode and/or a lower air supply mode. In the upper air supply mode, the free end T1 of the first air deflector 51 is abutted or close to the rear air duct wall 151 to guide the air-out air to flow through the upper half of the air-dispersing wall 131 of the front wall 13, so that the air-out air flow is blown out toward the front or the front upper direction, the air-out distance is longer, the air-out height is higher, a shower-type air supply effect is realized, and the shower-type air supply device is particularly suitable for the refrigerating mode, as shown in fig. 3. In the down air supply mode, the free end T2 of the first air deflector 51 is abutted or close to the front air duct wall 152 to guide the air outlet air to blow downwards through the air dispersing wall 141 of the bottom wall 14, so that the air supply air flow passes through the air dispersing wall 141 and then is blown downwards (can be directly under or obliquely upwards), and the air outlet air flow directly reaches the ground, thereby realizing a carpet type air supply effect, and being particularly suitable for a heating mode, as shown in fig. 4. As used herein, "against" refers to the direct contact of the corresponding air deflector with the duct wall, and "proximate" refers to the lack of direct contact, with some clearance. Preferably "against" to reduce air flow leakage, as shown in fig. 3 and 4.

In some embodiments, in the above-mentioned upper air supply mode, the second air deflector 52 stands against the inner side of the front wall 13 to shield the corresponding air dispersing wall 131 (the lower half below the first air deflector 51) so as to prevent the air supply flow reaching the outside of the housing 10 from flowing back into the housing 10 through the lower half of the air dispersing wall 131. In addition, in the aforementioned downward air supply mode, the second air deflector 52 is erected against the inner side of the front wall 13 of the housing 10 to guide the air-out flow downward so that the air-out flow better flows downward and the air-out flow is prevented from being blown out through the lower half of the air-dispersing wall 131.

In some embodiments, as shown in fig. 3, in the upper air supply mode, the height of the free end T1 of the first air deflector 51 is lower than the pivot end O1, that is, the first air deflector 51 gradually slopes upward from back to front, so as to better guide the air-out airflow forward and upward, thereby forming an upward air-out effect and improving the air supply distance. As shown in fig. 4, in the down-blowing mode, the free end T1 of the first air deflector 51 is higher than the pivot end O1, that is, the first air deflector 51 is gradually inclined downward from back to front, so as to better guide the air-out airflow downward, thereby forming a better sinking air-out effect and being more beneficial for the airflow to reach the ground.

In some embodiments, as shown in fig. 3 and 4, the pivot ends O1, O2 of the first air deflector 51 and the second air deflector 52 are respectively located at the middle and bottom of the air dispersing walls 131, 141 of the front wall 13 in the height direction, so that the first air deflector 51 can better reach the upper air supply mode and the lower air supply mode, and can better meet the inclination requirement of the first air deflector 51.

Further, as shown in fig. 3 and 4, when the second air deflector 52 is erected against the inner side of the front wall 13 of the housing 10, the free end T2 thereof is adjacent to the pivot end O2 of the first air deflector 51, so that in the upper air supply mode, the second air deflector 52 completely shields the corresponding air-distributing wall 131 (the lower half portion located below the first air deflector 51), and in the lower air supply mode, the second air deflector 52 better guides the air-out flow downward, avoiding the air-out flow from being blown out through the lower half portion of the air-distributing wall 131.

In some embodiments, as shown in fig. 5, the wall-mounted air conditioner indoor unit further has an intermediate air supply mode in which the free end T1 of the first air deflector 51 is abutted against the front duct wall 152 and the free end T2 of the second air deflector 52 is abutted against the rear duct wall 151, so as to guide the air-out air to be blown out through the lower half of the air-dispersing wall 131 of the front wall 13. In the middle air supply mode, the flow path of the air supply air flow is positioned between the upper air supply mode and the lower air supply mode, and the air supply device is suitable for a refrigerating mode and a heating mode, and enriches the choices of users. Further, in the intermediate air blowing mode, the free end T1 of the first air deflector 51 is positioned higher than the pivot end O1, and the free end T2 of the second air deflector 52 is positioned higher than the pivot end O2, that is, both the first air deflector 51 and the second air deflector 52 are inclined gradually downward from rear to front so as to better guide the air flow toward the front lower side.

In this way, the utility model utilizes the upper air supply mode to blow the air flow of the air supply forward or forward and upward, utilizes the middle mode to blow the air flow forward and downward, and utilizes the lower air supply mode to blow the air flow of the air supply forward and downward, thereby realizing the full-angle coverage of the indoor space. It should be understood that the above three air supplying modes are only preferable air supplying modes, and the positions of the first air deflector 51 and the second air deflector 52 can be arbitrarily adjusted to combine more diversified air supplying modes, which are not exemplified here.

Further, as shown in fig. 5, in the aforementioned intermediate air supply mode, the free end T2 of the second air deflector 52 is brought into close proximity with or against the outlet end N of the rear duct wall 151, and a close-proximity embodiment of both is illustrated. So that the second air deflector 52 forms an extension section of the rear air duct wall 151, the transition between the second air deflector 52 and the rear air duct wall 151 is smoother, and the loss of air flow at the joint of the two air deflectors is reduced.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
