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 and an air guide 50.

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 air deflector 50 is disposed inside the housing 10 and configured to adjust the flow direction of the air-out airflow to adjust the air volume distribution of the two air-dispersing walls 131, 141. For example, when the air guide plate 50 is guided 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 air deflector 50 is downwardly directed, the air output of the air dispersing wall 141 of the bottom wall 14 of the casing 10 can be increased; when the air guide plate 50 is guided downward and forward, 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 uniform.

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. The air distribution of the two air-diffusing walls 131 and 141 is adjusted by the air deflector 50 to adjust the air blowing direction of the casing 10, which makes the wall-mounted air conditioner have various air blowing modes.

In addition, the air deflector 50 is hidden in the shell 10, and the traditional air outlet is not formed in 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.

In some embodiments, as shown in fig. 3 and 4, the deflector 50 may be provided with opposite pivot ends O and free ends T. For example, in a wall-mounted air conditioning room in which the housing 10 is elongated and the longitudinal direction is parallel to the horizontal direction, the air guide plate 50 may be elongated and the pivot end and the free end may be both ends in the width direction of the air guide plate 50, respectively, and may be understood as both long sides of the air guide plate 50. The pivoting end O of the air deflector 50 is rotatably mounted to the housing 10, and the axis of rotation is parallel to the lateral direction of the housing 10, so that the air deflector 50 rotatably adjusts its angle (air guiding angle) with the horizontal plane, thereby adjusting the flow direction of the air-out air flow. It will be appreciated that when the air conduction angle is an elevation angle, the air outlet volume of the air dispersing wall 131 of the front wall 13 of the housing 10 is greater than the air outlet volume of the air dispersing wall 141 of the bottom wall 14 of the housing 10, and the larger the air conduction angle, the more the difference is apparent. When the air guide angle is the depression angle, the air outlet amount of the air dispersing wall 141 of the bottom wall 14 of the casing 10 is larger than the air outlet amount of the air dispersing wall 131 of the front wall 13 of the casing 10, and the larger the air guide angle is, the more the difference is apparent.

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 air deflection 50 has a forward air deflection position with the free end T against or proximate the rear duct wall 151 to direct the flow of the outlet air forward, as shown in fig. 3. The air deflection 50 also has a lower air deflection position with the free end T against or proximate the front duct wall 152 to direct the downward flow of the outlet air stream, as shown in fig. 4. The "abutting" air deflection 50 is in direct contact with the duct wall, and the "proximate" is not in direct contact, with some clearance. Preferably "against" to reduce air flow leakage, as shown in fig. 3 and 4.

In the front air guiding position, as shown in fig. 3, the air flow is totally or mainly blown to the air dispersing wall 131 of the front wall 13 of the casing 10, and then is blown forward (either right ahead or front upper) after passing through the air dispersing wall 131, so that the air outlet distance is longer, the air supply height is higher, a shower type air supply effect is realized, and the shower type air supply device is particularly suitable for a refrigerating mode. In the lower air guiding position, as shown in fig. 4, the air flow is totally or mainly blown to the air dispersing wall 141 of the bottom wall 14 of the casing 10, and then passes through the air dispersing wall 141 and then is blown downwards (either directly under or obliquely under), so that the air flow of the air outlet directly reaches the ground, thereby realizing a carpet type air supply effect, and being particularly suitable for a heating mode.

It will be appreciated that the leading and trailing wind positions are the two extreme positions at which the wind deflector 50 reciprocates. The air conditioner controller may also control the air deflection 50 to stay in any position between the front air deflection position and the lower air deflection position.

Further, as shown in fig. 3, in the front air guiding position, the height of the free end T of the air guiding plate 50 is lower than the pivoting end O, that is, the air guiding plate 50 is gradually inclined upwards from back to front, so as to better guide the air flow of the air outlet forward and upward, form the upward air outlet effect, and improve the air supply distance. As shown in fig. 4, in the lower wind guiding position, the free end T of the wind guiding plate 50 is higher than the pivot end O, that is, the wind guiding plate 50 is gradually inclined downwards from back to front, so as to better guide the wind outlet airflow downwards, thereby forming a better sinking wind outlet effect and being more beneficial for the airflow to reach the ground.

In some embodiments, as shown in fig. 3 and 4, in the front wind guiding position, the free end T of the wind deflector 50 is abutted or close to the outlet end N of the rear wind channel wall 151, which is illustrated. So that the air deflector 50 forms an extension section of the rear air duct wall 151, the transition between the air deflector 50 and the rear air duct wall 151 is smoother, and the loss of air flow at the joint of the two is reduced.

In some embodiments, the pivot end O of the deflector 50 may be located at a middle portion of the front wall 13 of the housing 10 in the height direction of the air dispersing wall 131 so as to be rotated upward to the aforementioned lower air guiding position and rotated downward to the aforementioned front air guiding position.

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.
