As shown in fig. 1 to 8, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and at least one adjusting plate 80.

An air outlet 12 is formed at a lower portion of the front side of the casing 10, and a plurality of air dispersing holes 13 are opened in a bottom wall 101 of the casing 10. The air outlet 12 and the plurality of air-dispersing holes 13 are used for discharging the air flow supplied from the inside of the casing 10 to adjust the indoor ambient air. A plurality of the air dispersing holes 13 may be arranged in an area of the bottom wall 101 of the housing 10 adjacent to the edge of the air outlet 12. The supply air flow is usually heat exchange air that exchanges heat with the heat exchanger 30, and when the air conditioner is in the cooling mode, the heat exchange air is cold air, and when the air conditioner is in the heating mode, the heat exchange air is hot air. Of course, the supply air flow can also be a fresh air flow.

Each adjusting plate 80 is provided with a plurality of adjusting holes 81 and configured to be capable of being attached to the bottom wall 101 of the casing 10 to translate, so as to adjust the overlapping degree of the plurality of adjusting holes 81 and the air diffusing holes 13 in at least a partial region of the bottom wall 101 of the casing 10, and thus change the air outlet area of each air diffusing hole 13 in the region. The adjustment plate 80 is always in abutment with the bottom wall 101 of the casing 10 during translation. When the overlapping ratio of the adjusting holes 81 and the air dispersing holes 13 is 100%, the air outlet area of the air dispersing holes 13 is the largest, as shown in fig. 6. When the air dispersing holes 13 are completely covered by the solid portion of the adjusting plate 80, the overlapping ratio of the adjusting holes 81 and the air dispersing holes 13 is zero, and the air outlet area of the air dispersing holes 13 is zero, as shown in fig. 7.

The number of the adjusting plates 80 may be one, so that the adjusting plates 80 adjust all the air dispersing holes 13. The number of the regulating plates 80 may be plural, and each of the regulating plates 80 corresponds to the air dispersing hole 13 of a partial area of the bottom wall 101. When one adjusting plate 80 is translated, the air outlet area of the air dispersing holes 13 corresponding to the other adjusting plates 80 is not changed, which provides more choices for users.

In the embodiment of the present invention, since the bottom wall 101 of the casing 10 of the wall-mounted air conditioner indoor unit is opened with a plurality of air-dispersing holes 13, it has a plurality of air-supply modes, for example:

first, the outlet 12 is opened, and the main part of the blowing airflow inside the casing 10 is blown into the room through the outlet 12. The other part of the main part of the blowing air flow is blown to the air diffusing holes 13, is dispersed by the air diffusing holes 13, and is blown downward into the room. The air supply airflow becomes softer after being scattered, an air supply effect close to no wind sensation is achieved, and comfortable air supply of the air conditioner is realized.

Secondly, the outlet 12 is closed (e.g. by the external air guiding plate), as shown in fig. 5. When the air outlet 12 is closed, all the air flow is forced to flow to the plurality of air-dispersing holes 13, so that the plurality of air-dispersing holes 13 can supply air with large air volume, and the effect of completely supplying air without wind sense is realized.

Because a plurality of scattered wind hole 13 are seted up on the diapire 101 of casing 10, can vertical air supply downwards, also remedied among the prior art and only utilized the air outlet air supply, lead to the not convenient for vertical air supply downwards's defect. Particularly, in the heating mode, the plurality of air dissipation holes 13 are used for supplying air vertically and downwards, so that the temperature of the area right below the indoor unit of the wall-mounted air conditioner is increased more quickly, and the problem that hot air is difficult to flow right below the indoor unit in the prior art is solved.

The embodiment of the utility model provides an in, wall-hanging air conditioning indoor set has still set up the regulating plate 80 that has a plurality of regulation holes 81, and usable regulating plate 80 adjusts the air-out area of scattered wind hole 13 to change the air output of the diapire 101 of casing 10, make it match the actual demand of user to the amount of wind.

The wall-mounted air conditioning indoor unit includes an outer air guide plate 50. The outer air guide plate 50 is rotatably installed to the housing 10 for opening or closing the air outlet 12. Of course, the outer wind deflector 50 may also have a function of guiding the air blowing direction of the air outlet 12 up and down. 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 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.

In some embodiments, as shown in fig. 6 and 7, the aforementioned at least one regulating plate 80 may be made to fit to the inner side surface of the bottom wall 101 of the housing 10. Therefore, the adjusting plate 80 can be hidden inside the casing 10, and the appearance of the wall-mounted air conditioning indoor unit is prevented from being affected. Referring to fig. 2 and 8, the ventilation area of the air dispersing holes 13 can be adjusted manually. Specifically, each adjustment plate 80 has a handle 82, and the handle 82 extends to the outside of the housing 10 through an abdicating hole 14 formed in the bottom wall 101 of the housing 10, so that the user can translate the adjustment plate 80 by translating the handle 82.

Further, considering that the total air outlet area of the plurality of air dispersing holes 13 is not large, the air outlet area does not need to be adjusted too finely, and the user generally only needs to adjust the air outlet area to the maximum air outlet area or adjust the air outlet area not to be air outlet. Therefore, the embodiment of the present invention designs the shape of the yielding hole 14 and the relative position of the yielding hole and the adjusting plate 80, when the handle 82 moves to the end of the yielding hole 14, the adjusting holes 81 of the adjusting plate 80 completely coincide with the air-dispersing holes 13 of the corresponding area, so that the air-out area reaches the maximum. When the handle 82 moves to the other end of the receding hole 14, the solid portion of the adjusting plate 80 completely covers each air-dispersing hole of the corresponding region, so that the air-outlet area is zero. On this basis, when the handle 82 is located between the two ends of the abdicating hole 14, the air outlet area will be located between the maximum air outlet area and the zero air outlet area. This makes the regulation of two gears of the biggest air-out area and not air-out very accurate, and adjusts very conveniently (move the handle to lean on in the most tip of abdicating hole 14 can), has satisfied the most commonly used regulation demand of user.

In alternative embodiments, adjustment plate 80 may also be driven in translation by electric means.

In some embodiments, as shown in FIG. 6, the adjustment holes 81 of each adjustment plate 80 may be shaped to match the positions of at least some of the dispersion wind holes 13 one-to-one. This allows for better correspondence of the adjustment holes 81 to the air dispersion holes 13. In some alternative embodiments, the area of the adjusting holes can be larger, so that one adjusting hole corresponds to a plurality of air dispersing holes.

As shown in fig. 1 and 5, the wall-mounted type indoor unit of an air conditioner may be an indoor part of an air conditioner that performs cooling/heating using a vapor compression refrigeration cycle. A heat exchanger 30 and a fan 40 are provided in the casing 10. 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, and completes forced convection heat exchange with the heat exchanger 30 to form heat exchange air.

Fig. 9 is a schematic view showing a structure of a casing in the wall-mounted type air conditioning indoor unit of fig. 1; fig. 10 is an enlarged view of fig. 9 at D.

As shown in fig. 3 to 10, the wall-mounted air conditioning indoor unit further includes at least one guide portion 70 and an air duct 20. Each flow guide part 70 is located inside the bottom wall 101 of the casing 10 and defines a flow passage 701 communicating with at least part of the dispersing air holes 13 together with the bottom wall 101 of the casing 10, and each regulating plate 80 is disposed in one of the flow passages 701. If only one flow guide part 70 is provided, the flow passage 701 of the flow guide part 70 communicates with all the air diffusing holes 13. If a plurality of flow guiding parts 70 are provided, the flow passage 701 of each flow guiding part 70 corresponds to one dispersion air hole 13, and each dispersion air hole 13 is ensured to correspond to one flow passage 701. The air outlet 12 is a long strip with a length direction parallel to the transverse direction of the housing 10, and the plurality of flow guiding portions 70 are arranged along the length direction of the air outlet 12, so that the area between the two flow guiding portions 70 can be used for installing the rotating shaft of the inner air guiding plate or the outer air guiding plate.

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 each flow guide part 70 and is communicated with each flow passage 701, so as to guide the blowing air flow to the air outlet 12 and the flow passage 701. The supply air flow entering the overflow passage 701 is blown out through the plurality of air-dispersing holes 13.

The individual air dissipation holes 13 in each air dissipation zone may be arranged in a matrix, see fig. 2. In addition, the air dispersing holes 13 may be circular holes, kidney-shaped holes, square holes, elliptical holes, triangular holes, polygonal holes, or other openings of various shapes.

In some embodiments, as shown in fig. 5-10, each flow guide 70 includes a channel apron 71 and a web 72. Wherein the channel containment flaps 71 extend upwardly from the inside surface of the bottom wall 101 of the housing 10 to define, in cooperation with the bottom wall 101 of the housing 10, the aforementioned overflow channels 701. The passage enclosure 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 connected to the bottom wall 101 of the housing. 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 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 air dispersing holes 13 can be effectively prevented by the stepped surface structure, and condensation water is prevented from dripping out through the air dispersing holes 13.

In some embodiments, as shown in fig. 5-10, each flow guide 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 of the present invention, as shown in fig. 3 and 4, the wall-mounted air conditioner indoor unit further includes an inner air deflector 60. The inner wind deflector 60 is rotatably installed inside the air outlet 12 for guiding the air outlet direction of the air outlet 12.

The wall-mounted type air conditioning indoor unit may be simultaneously installed with the inner air guide plate 60 and the outer air guide plate 50. The outer air guiding plate 50 is mainly used for opening and closing the air outlet 12, the inner air guiding plate 60 is located inside 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 60 is shielded inside the casing 10. When the outer air guiding plate 50 opens the air outlet 12, the inner air guiding plate 60 is used for guiding the air outlet direction of the air outlet 12, including swinging the air up and down.

In some embodiments, the inner air deflector 60 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 60 can guide the blowing air flow toward the flow passage 701, so that the blowing air flow can flow more smoothly toward the flow passage 701, and does not detour and bend into the flow passage 701 after rushing to the inner side of the outer air deflector 50, thereby causing large pressure loss.

In some embodiments, as shown in fig. 3 and 4, both side surfaces of the inner air deflection plate 60 are formed with a plurality of spherical recesses 61. This makes inner air deflector 60 also carried out the vortex to the air supply air current when the wind-guiding, makes it more dispersed, has improved the comfort level of air supply air current. The inner air deflector 60 is matched with the air dispersing holes 13, and the air flow is comfortable to process by utilizing different structures, so that the air supply flow is more comfortable, and the use experience of a user is improved.

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.
