The embodiment of the utility model provides a wall-hanging air conditioning indoor set. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

As shown in fig. 1 to 7, the wall-mounted air conditioning indoor unit of the present invention may generally include a casing 10 and at least one mesh fabric 90.

Wherein, the housing 10 is provided with at least one air outlet 13. The air exhaust hole 13 is a through hole penetrating the wall of the casing 10 for exhausting the supply air flow in the casing 10. The supply air flow refers to an air flow for adjusting the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, and fresh air in a fresh air mode, etc., which is acted on by a fan in the housing 10 to accelerate the flow out of the housing 10.

At least one mesh cloth 90 is installed on the casing 10 to cover the air outlet 13 formed on the casing 10, so that the air flow in the casing 10 is dispersed by the mesh cloth 90 and then discharged to the indoor environment through the air outlet 13. The mesh cloth 90 is formed with a plurality of densely arranged mesh holes 91 so that the air flow passing through the mesh cloth 90 is dispersed, and the mesh cloth 90 may be made of a fiber material.

The utility model discloses in the wall-hanging air conditioning indoor set of embodiment, because seted up exhaust hole 13 on the casing 10, and install the screen cloth 90 that covers exhaust hole 13. The partial or whole air supply air current of casing 10 blows to screen cloth 90, is broken up by screen cloth 90 the back, passes screen cloth 90, then discharges to the indoor environment through exhaust hole 13, adjusts indoor ambient air. The air flow becomes softer after being scattered, a no-wind effect is achieved, comfortable air supply of the air conditioner is achieved, human body feeling is more comfortable, and cold air/hot air is prevented from being directly blown to the human body at high speed to cause discomfort of the human body.

In some existing improved structures, a plurality of densely arranged micropores are formed in a shell, air is supplied to an indoor environment through the micropores, and a non-wind-sense air supply effect is achieved. However, since the casing is usually made of hard material, the processing of a plurality of densely arranged micropores with small pore diameters (the pore diameter of the micropores is usually small, for example, 1-10mm, otherwise the breeze effect cannot be achieved at all) has high process requirements, and the cost of the casing is increased.

And in the embodiment of the utility model provides an in, by the wind effect that looses of screen cloth 90 performance, only need set up on the casing 10 one or more great exhaust hole 13 can, need not to set up the less micropore in aperture on casing 10 at all, reduced casing 10's cost of manufacture from this, screen cloth 90 itself easily obtains and purchasing cost is lower, but also convenience of customers changes and washs.

It is preferable that the number of the exhaust holes 13 is plural, and one mesh cloth 90 corresponds to plural exhaust holes 13. Therefore, the caliber of the air exhaust holes 13 is relatively small, and the solid parts among the air exhaust holes 13 provide stronger support and fixation for the mesh cloth 90, so that the position of the mesh cloth is more stable. Of course, in alternative embodiments, a plurality of webs 90 may be provided, such that each vent hole 13 corresponds to one web 90.

Further, for arrangements in which multiple webs 90 are provided, the dimensions of each web 90 may be set differently or not identical. The so-called specifications include the size of the mesh 91, the opening density, the shape of the mesh, and the like.

In some embodiments of the present invention, the number of the air exhaust holes 13 may be plural, and the flow cross section of each air exhaust hole 13 is gradually increased in the flow direction of the air supply flow. That is, each air discharge hole 13 is formed in a divergent shape. Therefore, the air supply flow flows outwards in the air exhaust holes 13 in a diffused manner, and after the air supply flow flows out of the air exhaust holes 13 for a certain distance, the air outlet flows of the adjacent air exhaust holes 13 can be mutually intersected and mutually impacted, so that the impact force of the flows is mutually offset, the flows are closer to natural wind, and the comfort level is higher.

In other embodiments of the present invention, the number of the air exhaust holes 13 may be plural, and the plural air exhaust holes 13 are configured to have different air outlet directions. The design also enables the air outlet flows of the air outlet holes 13 to mutually intersect and mutually impact, so that the impact force of the flows is mutually offset, the flows are closer to natural wind, and the comfort level is higher.

In some embodiments of the present invention, as shown in fig. 1 to 7, an air outlet 12 is disposed at the bottom of the front side of the casing 10, and the at least one air outlet 13 is disposed on the bottom wall 101 of the casing 10. The air outlet 12 is used to discharge the air flow generated in the housing 10 to the indoor environment to condition the indoor air.

In some embodiments, as shown in fig. 1 and 8, an outer air guiding plate 50 is disposed at the air outlet 12, and the outer air guiding plate 50 is rotatably installed at the air outlet 12 for guiding the air outlet direction of the air outlet 12 and also for opening and closing the air outlet 12.

In some embodiments, the outlet 12 may be an elongated shape with a length direction parallel to the transverse direction of the housing 10 (the transverse direction of the housing 10 is already indicated in the figure). The number of the at least one exhaust hole 13 is plural, and the plurality of exhaust holes 13 are arranged at intervals along the length direction of the air outlet 12 and are disposed at a position close to the rear side of the air outlet 12. The front edge of the bottom wall 101 of the casing 10 forms the rear edge of the air outlet 12, and the plurality of exhaust holes 13 are adjacent to the rear edge of the air outlet 12, that is, adjacent to the front edge of the bottom wall 101 of the casing 10, so as to better interface with the air duct 20 inside the casing 10.

In the above embodiment, since the plurality of air exhaust holes 13 are formed in the bottom wall 101 of the casing 10, the wall-mounted air conditioner indoor unit can supply air towards the right below of the casing 10, and the defect that the conventional wall-mounted air conditioner indoor unit only supplies air towards the front lower side by means of the air outlet and is inconvenient to supply air vertically downwards is overcome. Especially when the air conditioner is in the mode of heating, the utility model discloses utilize the vertical air supply downwards in a plurality of holes of airing exhaust 13 for regional temperature risees faster under wall-hanging air conditioning indoor set, and the effect of heating is better.

In some embodiments, as shown in fig. 2 and 3, each of the air outlet holes 13 may have a rectangular shape extending back and forth in the length direction, and the air outlet holes 13 may be arranged at equal intervals along the length direction of the air outlet 12, so as to make the bottom of the wall-mounted air conditioning indoor unit more neat and beautiful.

In some alternative embodiments, the ventilation holes 13 may be circular holes, kidney-shaped holes, square holes, elliptical holes, triangular holes, polygonal holes, or other through holes with various shapes.

In some embodiments, the mesh 90 may be removably mounted to the housing 10 to facilitate replacement and cleaning of the mesh 90. For example, an insertion slot may be formed inside the bottom wall 101 of the housing 10, and an insertion opening of the insertion slot is located at the front end of the bottom wall 101 of the housing 10, so that the mesh cloth 90 is inserted into the insertion slot from the insertion opening to achieve detachable installation.

Fig. 8 is an enlarged cross-sectional view of the wall-mounted air conditioning indoor unit shown in fig. 1; FIG. 9 is an enlarged view at D of FIG. 8; fig. 10 is a schematic view showing a structure of a casing in the wall-mounted type air conditioning indoor unit of fig. 1; fig. 11 is an enlarged view of fig. 10 at E.

In some embodiments of the present invention, as shown in fig. 8 to 11, the wall-mounted air conditioning indoor unit may further include at least one guide portion 70 and an air duct 20. Each of the flow guides 70 is located inside the bottom wall 101 of the casing 10 and defines a flow passage 701 communicating with the plurality of exhaust 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 exhaust holes 13. The mesh cloth 90 is in a plurality, and each mesh cloth 90 is located in one of the flow passages 701.

The air duct 20 is formed in the housing 10 and includes a rear wall 21 (or volute) and a front wall 22 (or tongue). The lower 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 blowing air flow entering the overflow passage 701 is blown out through the plurality of air discharge holes 13.

For example, as shown in fig. 10, the outlet 12 may be an elongated shape with a length direction parallel to the transverse direction of the housing 10. The number of the flow guide parts 70 is multiple, the number of the mesh cloth 90 is the same as that of the flow guide parts 70, and each mesh cloth 90 is installed in the flow passage of one flow guide part. As shown in fig. 10, the number of the flow guide portions 70 is two, and the two flow guide portions 70 are spaced apart in the lateral direction of the housing 10, i.e., spaced apart left and right. The area between the two deflectors 70 can be used for installing the rotating shaft of the inner air deflector or the outer air deflector.

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 that communicates exhaust hole 13. When the outlet 12 is in the open state, the main part of the supply airflow inside the housing 10 will be blown into the room from the outlet 12, and the other part of the supply airflow outside the main part will enter the flow passage 701, and will be blown toward the plurality of air outlet holes 13 under the guidance of the flow guide part 70, and will be blown down into the room after being scattered by the plurality of air outlet 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 external air deflector 50), all the air flow is forced to flow to the plurality of air outlet holes 13, so that the plurality of air outlet holes 13 supply air with large air volume, thereby achieving the effect of completely supplying air without wind sensation.

In some embodiments of the present invention, the outer 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 air outlet, please refer to fig. 1 specifically. In the breeze mode, the outer air guiding plate 50 is located close to the position for 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 outer air guiding plate 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 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 overflow passage 701, is blown to the air discharge holes 13 under the guidance of the guide part 70, is scattered by the air discharge holes 13, and is then 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 external air deflector 50). When the air outlet 12 is closed, all the air supply flow is forced to flow to the plurality of air exhaust holes 13, so that the plurality of air exhaust holes 13 supply air with large air volume, and the effect of completely supplying air without wind sense is realized.

Thirdly, the outer wind guiding plate 50 is moved to a breeze mode in which the edge of the outer wind guiding plate is spaced from the edge of the wind outlet 12 so as to discharge wind, as shown in fig. 8, so that the wind is discharged from the space and the plurality of wind discharging holes 13 together, thereby achieving a greater degree of non-wind effect.

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 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 exhaust holes 13, and cold air or hot air is prevented from directly blowing the 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. 8 and 9, 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 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.

The utility model discloses an in this embodiment, passageway apron 71 has not only injectd overflow passage 701 with the diapire 101 of casing 10 jointly, can also be with air supply air current direction exhaust hole 13. The connecting plate 72 extends rearward from the top end of the passage enclosure 71 to connect with the front end of the rear wall 21 of the air chute 20, so that the connecting plate 72 corresponds to an extension of the rear wall 21 of the air chute 20. This makes the transition of the connection between the rear wall 21 of the air duct 20 and the connecting plate 72 more natural and smooth, and does not cause extra on-way resistance to the air flow, so that the air flow is smoother.

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, the step surface structure can effectively prevent condensation at the air exhaust hole 13 and prevent condensed water from dripping out through the air exhaust hole 13.

In some embodiments of the present invention, as shown in fig. 10 and 11, 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 outer aviation baffle 50 closes air outlet 12, the air supply air current all flows to overflowing passageway 701 under the compulsory effect of fan, and it is very big to overflow passageway 701 internal gas pressure, if there is the gap between diapire 101 of water conservancy diversion portion 70 and casing 10, will arouse the leakage problem very easily, the embodiment of the utility model provides a then can avoid appearing this problem.

In some embodiments of the present invention, as shown in fig. 4 and 6, the wall-mounted air conditioner indoor unit further includes an inner air deflector 80. The inner wind deflector 80 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 is simultaneously provided with the inner air guide plate 80 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 80 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 80 is shielded at the inner side of the shell 10. When the outer air guiding plate 50 opens the air outlet 12, the inner air guiding plate 80 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 80 is configured to direct the supply airflow 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 80 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.

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, as shown in fig. 1 and 4, at least one lateral side wall of the housing 10 may be provided with a plurality of air dispersing holes 14 for discharging the air flow. For example, it is preferable to provide both lateral side walls of the casing 10 with the 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 air dispersing holes 14 may be a long strip extending in the front-rear direction, and the plurality of air dispersing holes 14 are arranged at intervals in the up-down direction. The length of each air dispersing hole 14 can be made smaller in the direction from top to bottom, see fig. 1. In addition, the air diffusing holes can also be circular holes, elliptical holes or other shapes.
