In some embodiments, a plurality of first air dispersing holes 13 may be formed in the bottom wall of the casing 10 for discharging the air flow in the casing 10. Therefore, the air supply mode of the air conditioner is more diversified, the selection of a user is enriched, and the user experience is improved. For example, the air outlet 12 may be selectively opened to simultaneously discharge air from the air outlet 12 and the plurality of first air-dispersing holes 13, thereby achieving large-air-volume cooling/heating. The air outlet 12 can be selectively closed to supply air through the micropores only through the first air-dispersing holes 13 and the second air-dispersing holes 14, so that a completely non-wind-feeling air supply effect is realized. In addition, the wall-mounted air conditioner indoor unit can supply air vertically downwards through the first air dispersing holes 13, and the defect that a traditional air outlet is not beneficial to supplying air vertically downwards is overcome. In the heating mode of the wall-mounted air conditioner indoor unit, the plurality of first air dispersing holes 13 are used for vertically and downwards supplying air, so that the temperature of the area right below the wall-mounted air conditioner indoor unit is increased more quickly. As shown in fig. 5, the opening areas of the first air dispersing holes 13 may be close to the edge of the air outlet 12.

In some embodiments, as shown in fig. 1, at least one lateral side wall of the casing 10 may be provided with a plurality of second air dispersing holes 14 for discharging the air flow. For example, it is preferable that both lateral side walls of the casing 10 are provided with the second air dispersing holes 14. Therefore, the air supply airflow can be blown out forwards and downwards, and can be blown out leftwards and rightwards, so that the air outlet angle range is larger, the air supply airflow is more dispersed, the air supply airflow is more quickly and sufficiently fused with indoor air, the airflow is softer, and the requirement of a user on comfortable air supply of the air conditioner is met. Specifically, each of the second air dispersing holes 14 may be a long strip extending in the front-rear direction, and the plurality of second air dispersing holes 14 are arranged at intervals in the up-down direction. The lengths of the second air dispersing holes 14 are sequentially reduced in the top-to-bottom direction, as shown in fig. 1. In addition, the second air dispersing hole can also be a circular hole, an elliptical hole or other shapes. Can make a plurality of second wind holes that disperse all be rectangular crooked shape to increase the irregularity degree of air-out direction, make the air current more be close to natural wind.

The embodiment of the utility model provides a make air conditioner air supply mode more diversified, richened user's selection, promoted user experience. An external air deflector 50 for opening and closing the air outlet 12 is disposed at the air outlet 12. When the air conditioner operates, the external air deflector 50 can be controlled to open the air outlet 12, and air is simultaneously discharged from the air outlet 12, the plurality of second air-dispersing holes 14 and the plurality of first air-dispersing holes 13, so that large-air-volume refrigeration/heating is realized. The outer air deflector 50 can also be controlled to close the air outlet 12, and the plurality of second air-dispersing holes 14 and the plurality of first air-dispersing holes 13 can perform breeze air-out, so that a completely non-wind-sensing air supply effect is realized. Or, the outer air guiding plate 50 may be adjusted to have a slit with the edge of the air outlet 12, so that the second air dispersing holes 14, the first air dispersing holes 13 and the slit can perform breeze air outlet together, thereby not only ensuring air supply comfort, but also increasing air volume.

The wall-mounted air conditioner indoor unit can further comprise a human detection sensor and a controller. The human body sensor is mounted on the casing 10 and used for detecting whether a human body enters the air outlet coverage range of the air outlet 12, and specifically, the human body sensor can be an infrared sensor. Based on this, an alternative non-wind-sensing control mode is as follows: when the human body sensor detects that the human body enters the air outlet coverage range, a human body sensing signal is formed, and the human body sensing signal is transmitted to the controller. The controller controls the outer air deflector 50 to close the air outlet 12, so that the air conditioner can completely supply air without wind sense through the plurality of second air dispersing holes 14 and the plurality of first air dispersing holes 13, and cold air or hot air is prevented from directly blowing to a human body. When the human body sensor detects that the human body leaves the air outlet coverage area, the controller controls the outer air deflector 50 to open the air outlet 12, and the air is normally supplied.

As shown in fig. 5, the first air dispersing holes 13 may be formed in a diamond shape as a whole. Compare in the circular micropore of conventional adoption, the embodiment of the utility model provides a rhombus hole edges and corners that adopts is more clear, and is stronger to the effect of breaing up of air current. Further, the plurality of first air dispersing holes 13 may be arranged in a plurality of rows arranged in front and rear, and the first air dispersing holes 13 in each row are arranged in the lateral direction of the casing 10 and communicate with each other. This structure increases the air volume of the plurality of first air-dispersing holes 13 as a whole.

Fig. 6 is an enlarged cross-sectional view of the wall-mounted indoor unit of the air conditioner shown in fig. 1; fig. 7 is a schematic view showing a structure of a casing in the wall-mounted type air conditioning indoor unit of fig. 1; FIG. 8 is an enlarged view at B of FIG. 7; fig. 9 is a rear side view angle schematic of the housing of fig. 7.

As shown in fig. 6 to 9, the outlet 12 may be an elongated shape whose longitudinal direction is parallel to the longitudinal direction of the housing 10. At least one slide rail set is disposed on the inner side of the casing 10, and each slide rail set includes two slide rails 16 arranged along the length direction of the casing 10 and respectively extending along the width direction of the air outlet 12. Both ends of each air dispersing filter screen 80 are slidably mounted on the two slide rails 16 of one slide rail set respectively so as to slide to a filtering position and a non-filtering position.

Further, the air outlet 12 may be located at the lower front portion of the housing 10, and each slide rail 16 extends from the air outlet 12 to the rear above the bottom wall 101 of the housing 10, so that the air-dispersing filter 80 is located above the bottom wall 101 of the housing 10 when in the non-filtering position.

As shown in fig. 6 to 9, the wall-mounted air conditioning indoor unit further includes a guide portion 70 and an air duct 20. The flow guide portion 70 is located inside the bottom wall 101 of the casing 10, and defines a flow passage 701 communicating with the plurality of first air-dispersing holes 13 together with the bottom wall 101 of the casing 10. The air guide part 70 is provided with a gap for allowing the slide rail 16 and the air dispersing filter 80 to pass through. The air dispersion screen 80 will pass through the gap as it moves from the filtering position to the non-filtering position.

The air duct 20 is formed within the housing 10 and is defined by a rear wall 21 (or volute) and a front wall 22 (or tongue). The front end of the rear wall 21 is connected to the rear end of the flow guide portion 70 and is communicated with the flow passage 701, so as to guide the air flow to the air outlet 12 and the flow passage 701. The air flow entering the flow passage 701 is blown out through the plurality of first air-dispersing holes 13. The wall-mounted air conditioner indoor unit may be an indoor part of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. A heat exchanger 30 and a fan 40 are provided in the casing 10. The fan 40 may be a cross-flow fan, and under the action of the fan 40, the indoor air enters the casing 10 through the air inlet 11 at the top of the casing 10, completes forced convection heat exchange with the heat exchanger 30 to form heat exchange air, and then blows toward the air outlet 12 under the guidance of the air duct 20.

The flow guide 70 includes a passage fence 71 and a connection plate 72. Wherein the channel containment flaps 71 extend upwardly from the inside surface of the bottom wall 101 of the housing 10 for defining the aforementioned overflow channels 701 in cooperation with the bottom wall 101 of the housing 10. And the channel baffle 71 is provided with a gap for allowing the sliding rail 16 and the air dispersing filter screen 80 to pass through.

The passage fence 71 specifically includes a rear plate and left and right side plates extending forward from both lateral ends of the rear plate, and front ends of the two side plates are joined to the bottom wall 101 of the housing 10. The connecting plate 72 extends rearward from the top end of the passage fence 71 to meet the front end of the rear wall 21 of the air chute 20. In this embodiment, the passage enclosure 71 not only defines the flow passage 701 together with the bottom wall 101 of the casing 10, but also guides the flow of the supply air to the plurality of first air-dispersing holes 13. The connecting plate 72 extends from the top end of the channel baffle 71 to connect with the front end of the rear wall 21 of the air duct 20, so that the connecting plate 72 is equivalent to an extension of the rear wall 21 of the air duct 20, which makes the connection transition between the rear wall 21 of the air duct 20 and the connecting plate 72 more natural and smooth without causing extra on-way resistance to the air flow.

In the above embodiment, the air flow is guided forward by the rear wall 21 of the air duct 20 and the connecting plate 72, and then bends downward to enter the flow passage 701, so that the bottom wall 101 of the housing 10, the rear wall of the passage baffle 71 and the rear wall 21 of the air duct 20 form a step surface. When the wall-mounted air conditioner indoor unit operates in a refrigeration mode, condensation at the first air dissipation holes 13 can be effectively prevented by the step surface structure, and condensed water is prevented from dripping out through the first air dissipation holes 13.

In some embodiments, as shown in fig. 7-8, the deflector 70 is an integral piece with the housing 10. The design makes the structure simpler on the one hand, has saved the assembly work in later stage, and on the other hand also makes the position of being connected of water conservancy diversion portion 70 and the diapire 101 of casing 10 not have any gap, can avoid the air supply air current to leak through the gap between the two and flow back to the inside of casing 10 (the inside in non-wind channel 20), causes cold volume/heat waste. Especially, when the outer air deflector 50 closes the air outlet 12, the air flow of the supply air is forced to flow to the flow passage 701 by the fan, the air pressure in the flow passage 701 is large, and if a gap exists between the air guide part 70 and the bottom wall 101 of the housing 10, a leakage problem is easily caused.

In some embodiments, as shown in fig. 3, the wall-mounted air conditioning indoor unit is further provided with an inner air deflector. The inner air guiding plate is located at the inner side of the outer air guiding plate 50, and when the outer air guiding plate 50 is in a state of closing the air outlet 12, the inner air guiding plate is shielded at the inner side of the casing 10. When the outer air guiding plate 50 opens the air outlet 12, the inner air guiding plate is used for guiding the air outlet direction of the air outlet 12, including swinging the air up and down.

The inner air deflector is configured to direct the supply air flow toward the flow passage 701. As can be seen from the above, when the air outlet 12 is in the closed state, the air flow will flow to the flow passage 701. At this time, the inner air deflector can guide the air flow toward the flow passage 701, so that the air flow can flow more smoothly toward the flow passage 701, and does not detour into the flow passage 701 after rushing to the inner side of the outer air deflector 50, thereby causing large pressure loss.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
