Fig. 1 is a schematic structural view of an air deflector 50 for a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; FIG. 2 is an enlarged view at A of FIG. 1; fig. 3 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention.

An aspect of the present invention provides an air deflector 50 for a wall-mounted air conditioner indoor unit, in which the air deflector 50 is movably disposed at an air outlet 12 of a casing 10 of the wall-mounted air conditioner indoor unit, so as to guide an air outlet direction of an air flow. The supply air flow in this embodiment is usually heat exchange air, and of course, may also be fresh air flow.

As shown in fig. 1 to 3, the wind deflector 50 of the embodiment of the present invention may generally include a plate body 51 for guiding wind. The plate body 51 includes a plate body 511 and a boss portion 512 protruding from an inner side face 5112 of the plate body 511, so that an edge of the plate body 511 constitutes a thinned edge portion 5110 around the periphery of the boss portion 512. The plate body 511 constitutes a main body of the plate body 51, and the inner side surface 5112 of the plate body 511 refers to a surface facing the inside of the outlet 12 when the air guide plate 50 is in a state of closing the outlet 12. On the other hand, the portion of the plate body 511 not covered by the boss portion 512, that is, the portion surrounding the boss portion 512, is thinner because the boss portion 512 is not provided, and constitutes the aforementioned thinned edge portion 5110. For example, as shown in fig. 1 and 2, the plate body 511 has a substantially elongated rectangular shape as a whole, and the overall shape of the boss portion 512 is matched with the shape of the plate body 51, and is slightly smaller than the plate body 511 in size, thereby forming a thinned edge portion 5110 in a square frame shape. Of course, it is preferable that the plate body 51 be integrally formed.

The utility model discloses aviation baffle 50 is at the during operation, and the inboard of plate body 51 leads the air supply air current towards the inside of air outlet 12, blows to the surperficial back of boss portion 512 when the air supply air current, will follow boss portion 512 surface to diffusion all around, until leaving the surface of boss portion 512, flows to the peripheral attenuate edge part 5110 of boss portion 512. Since the thinned edge portion 5110 is thinner, the airflow flowing space becomes wider, the blowing airflow can flow out of the plate body 51 more smoothly and quickly, and the airflow flowing loss is smaller. In addition, because the process that the air current of supplying air flows out of plate body 51 is more smooth and rapid, also can reduce the production of plate body 51 edge condensation, avoid or reduce because of the condensation produces drips, blows water phenomenon. When the air conditioner operation refrigeration mode, the temperature of aviation baffle 50 is lower, and the condensation phenomenon appears in the marginal portion easily, the embodiment of the utility model provides an overcome this defect promptly.

In addition, it is understood that the air guide plate 50 may include not only the plate body 51 but also a connection portion for connecting with the casing 10 of the wall-mounted air conditioning indoor unit. For example, as shown in fig. 1 and 2, the air deflection plate 50 further includes a plurality of connecting arms 52, each connecting arm 52 extending from a surface of the boss portion 512 and terminating in a distal end for rotatably mounting to the housing 10. For example, in the case of the elongated air guide plate 50, the plurality of connection arms 52 may be arranged at intervals along the longitudinal direction of the plate body 51. For example, three connecting arms 52 are provided, two of the connecting arms 52 being provided at positions adjacent to both ends of the plate body 51 in the longitudinal direction, and one connecting arm 52 being provided at a central portion of the plate body 51 in the longitudinal direction.

The interior of the housing 10 is provided with a drive mechanism for driving the connecting arm 52 in rotation. The driving mechanism may be a motor, preferably a stepping motor, so as to facilitate accurate control of the rotation angle of the air deflector 50.

Of course, in alternative embodiments, the air deflector 50 may be connected to the housing 10 by other movement means, including translation, a combination of translation and rotation, and the like. These methods are common in the air conditioning field, and detailed descriptions of the specific form and driving mechanism are omitted.

In some embodiments of the present invention, the included angle between each end face 5122 of the boss portion 512 and the inner side face 5112 of the plate body 511 may be an obtuse angle. Specifically, as shown in fig. 1 and 2, the boss portion 512 is square, and has a large plane for guiding air (facing the inside of the air outlet 12 for guiding air) and four end faces 5122, and the four end faces 5122 form an obtuse angle with the inner side face 5112 (i.e., the portion covered by the boss portion 512) of the plate body 511. For example, the obtuse angle can be between 95 ° and 150 °, preferably between 100 ° and 120 °.

In this way, when the blowing air flow flows from the surface of the boss portion 512 to the inner surface 5112 of the plate body 51, the angle change is made more gradual, the flow loss is smaller, and the noise is smaller. The inventors have found that if the angle is set to the conventional right angle, the supply air flow is caused to abruptly spread after escaping from the surface of the boss portion 512, a large flow loss is generated, and a large noise is generated. And setting the angle between 95 ° and 150 ° effectively alleviates this problem. Setting this angle at 100 ° to 120 ° significantly alleviates or even substantially avoids the above-mentioned problems.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, the plate body 51 may be made to be a long strip shape, and both ends of the length direction of the plate body have flanges 501 bending toward the inner side of the plate body 511, and each flange 501 and the end face 5122 of the boss portion 512 adjacent to the flange 501 are disposed at an interval to form a diversion trench 503.

In the above embodiment, by providing two guiding grooves 503, the air flows at two ends of the plate body 51 in the length direction can flow along the width direction of the plate body 51 under the guidance of the guiding grooves 503, i.e. flow upwards, forwards or downwards out of the plate body 51, so as to avoid or reduce the influence on the air volume caused by the air flow that flows out of the air deflector 50 along the length direction of the air deflector 50 and thus the air flow cannot smoothly flow out of the air outlet 12.

In some embodiments of the present invention, as shown in fig. 1 and 2, the thickness of the boss portion 512 is made larger than the thickness of the plate body 511. In this way, when the total thickness of the plate body 51 (i.e., the sum of the thickness of the boss portion 512 and the thickness of the plate body 511) is not too large, the thickness of the boss portion 512 is made larger, and the boss portion 512 is made relatively thicker, so that the diffusion space is larger in the process of the supply air flow flowing from the surface of the boss portion 512 to the thinned edge portion 5110, so that the supply air flow can flow out of the plate body 51 more smoothly and quickly, the air flow loss is smaller, the anti-condensation effect is better, and the occurrence of edge condensation of the plate body 51 is more effectively avoided or reduced.

On the other hand, the embodiment of the utility model provides a wall-hanging air conditioning indoor set is still provided.

Fig. 4 is an enlarged cross-sectional view of the wall-mounted air conditioning indoor unit shown in fig. 3; FIG. 5 is an enlarged view at B of FIG. 4; fig. 6 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 4 in a state where the air guide plate 50 is opened.

As shown in fig. 3 to 6, the wall-mounted air conditioning indoor unit may generally include a casing 10 and a louver 50 according to any one of the above embodiments. Wherein, an air outlet 12 is formed at the bottom of the front side of the housing 10. In the embodiment illustrated in the figures, the outlet 12 opens towards the front and downwards. In some alternative embodiments, the outlet 12 may be opened directly below or directly in front.

The air guide plate 50 is disposed at the air outlet 12. In the embodiment shown in fig. 3 to 6, the air deflector 50 is rotatably mounted at the outlet 12 for guiding the air outlet direction of the outlet 12 and also for opening and closing the outlet 12.

The air guiding plate 50 is configured to move to a breeze mode in which the edge thereof is spaced from the edge of the air outlet 12 for discharging air, as shown in fig. 4. In the breeze mode, the air deflector 50 is located close to the position closing the air outlet 12, but does not completely close the air outlet 12, but keeps a certain distance from the edge of the air outlet 12, and the width of the distance may be 0.5-10 cm. In this way, the blowing airflow is allowed to flow out of the outlet 12 from the gap. Because the air-out area is far less than whole air outlet 12 for the air-out air current is more slight, realizes the breeze effect, and this mode is suitable for the lower condition of refrigerating output/heating capacity demand. Moreover, since the air flow is blown out from the edge of the air deflector 50, the air flow does not blow directly to the human body in a large air volume manner, and discomfort of the human body can be avoided.

In some embodiments of the present invention, a plurality of air dispersing holes 13 are disposed in the area of the bottom wall 101 of the casing 10 near the air outlet 12 for exhausting the air flow in the casing 10. The air outlet 12 is open forward and downward, and the front edge of the bottom wall 101 of the housing 10 forms the lower edge (also the rear edge) of the air outlet 12, and the area where the air dispersing holes 13 are located is adjacent to the front edge of the bottom wall 101.

The air-dispersing holes 13 may be arranged in a matrix, see fig. 3. 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.

The utility model discloses among the wall-hanging air conditioner indoor set, because seted up a plurality of scattered wind holes 13 on the diapire 101 of casing 10 for wall-hanging air conditioner indoor set can supply air towards casing 10 under for it only relies on the air outlet to supply air below forward to have compensatied in traditional wall-hanging air conditioner indoor set, is not convenient for the defect of vertical air supply down. Particularly, when the air conditioner is in a heating mode, the plurality of air dissipation holes 13 are used for vertically and downwards supplying air, so that the temperature of the area right below the indoor unit of the wall-mounted air conditioner is increased more quickly, and the heating effect is better.

As shown in fig. 3 to 6, in some embodiments of the present invention, the wall-mounted air conditioning indoor unit may further include 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 air dispersing holes 13 together with the bottom wall 101 of the casing 10, so that the supply air flow in the flow passage 701 is blown out through the plurality of air dispersing holes 13.

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 utility model discloses among the wall-hanging air conditioner indoor set of embodiment, because the inboard of the diapire 101 of casing 10 has set up water conservancy diversion portion 70, make water conservancy diversion portion 70 and the diapire 101 of casing 10 inject the passageway 701 that overflows of intercommunication scattered wind hole 13. When the outlet 12 is in the open state, the main part of the air flow inside the casing 10 will be blown into the room from the outlet 12, and the other part of the air flow outside the main part of the air flow will enter the flow passage 701, and will be blown to the plurality of air dispersing holes 13 under the guidance of the flow guide part 70, and will be blown down into the room after being dispersed by the plurality of air dispersing holes 13. The airflow becomes softer after being scattered, a no-wind effect is achieved, and comfortable air supply of the air conditioner is realized. When the air outlet 12 is closed (for example, closed by the air deflector 50), 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 perform large-air-volume air supply, and the effect of completely supplying air without wind sensation is achieved.

In a word, the embodiment of the utility model provides a through above-mentioned scheme for wall-hanging air conditioning indoor set has diversified no wind sense air supply mode, 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 enters the flow passage 701, is guided by the guide part 70, is blown to the air dispersing holes 13, is dispersed by the air dispersing 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 (for example, closed by the air guide plate 50). 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.

Thirdly, the air deflector 50 moves to a breeze mode in which the edge of the air deflector is spaced from the edge of the air outlet 12 to facilitate air outlet, as shown in fig. 4, so that the spaced air-dispersing holes 13 can supply air without wind.

In some embodiments, the wall-mounted air conditioning indoor unit may further include 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 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 range, the controller controls the air deflector 50 to open the air outlet 12, and the air is normally supplied.

In some embodiments, as shown in fig. 4-5, the flow guide 70 includes a channel containment plate 71 and a connecting 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. 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, 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 air deflector 50 closes the air outlet 12, the air flow of the air supply 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, the leakage problem is easily caused.

In some embodiments of the present invention, as shown in fig. 6, the wall-mounted indoor unit of an air conditioner 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 air conditioning indoor unit is simultaneously provided with an inner air deflector 60 and an air deflector 50. The air deflector 50 is mainly used for opening and closing the air outlet 12, the inner air deflector 60 is located inside the air deflector 50, and when the air deflector 50 is in a state of closing the air outlet 12, the inner air deflector 60 is shielded inside the casing 10. When the air outlet 12 is opened by the air deflector 50, the inner air deflector 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 toward the inner side of the air deflector 50, thereby causing a large pressure loss.

The utility model discloses machine in wall-hanging air conditioning can be for utilizing vapor compression refrigeration cycle system to carry out the indoor portion of the air conditioner that refrigerates/heat. As shown in fig. 4 and 6, a heat exchanger 30 and a fan 40 are provided in the casing 10. Under the action of the fan 40, 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 is blown to the air outlet 12 and the overflowing channel 701 under the guidance of the air duct 20.

In some embodiments of the present invention, a plurality of air inlet micropores 14 are disposed on the lateral side wall 102 of the casing 10, and the plurality of air inlet micropores 14 are located in the region near the front wall 103 of the casing 10, so as to introduce the indoor air into the casing 10, thereby increasing the air intake of the casing 10, and increasing the heat exchange efficiency of the front section of the heat exchanger 30.

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.
