The invention aims to provide a wall-mounted air conditioner indoor unit capable of realizing comfortable air supply.

The invention further aims to enhance the non-wind-sensing air supply effect of the wall-mounted air conditioner indoor unit.

In particular, the present invention provides a wall-mounted air conditioning indoor unit, comprising:

the air outlet penetrates through the front side and the transverse two sides of the shell and is used for exhausting air flow in the shell; and

the outer air guide plate is movably arranged on the shell and comprises an air guide plate body and two end plate parts bent and extended from the two transverse ends of the air guide plate body, and the air guide plate body and the two end plate parts are respectively used for opening and closing the air outlets on the front side and the two transverse sides of the shell.

Optionally, one or both end plate portions are provided with a plurality of first air dispersing holes for discharging the air flow in the housing.

Optionally, the plurality of first wind dispersing holes include a plurality of circular holes and a plurality of elliptical holes, and the wind outlet area of the elliptical holes is larger than the wind outlet area of the circular holes.

Optionally, the bottom wall of the casing is provided with a plurality of second air dispersing holes for discharging the air supply flow in the casing.

Optionally, the opening area of the second air dispersing holes is close to the edge of the air outlet.

Optionally, the wall-mounted air conditioner indoor unit further comprises a flow guide part, which is located inside the bottom wall of the casing and defines an overflowing channel communicated with the plurality of second air dispersing holes together with the bottom wall of the casing; and the air duct comprises a front wall and a rear wall, the front end of the rear wall of the air duct is connected with the rear end of the flow guide part and communicated with the overflowing channel so as to guide the air supply airflow to the air outlet and the overflowing channel.

Optionally, the flow guide portion comprises: the channel enclosure plate extends upwards from the inner side surface of the bottom wall of the shell and is used for defining a flow channel together with the bottom wall of the shell; and the connecting plate extends backwards from the top end of the channel baffle plate so as to be connected with the front end of the rear wall of the air channel.

Optionally, the flow guide is an integral piece with the housing.

The wall-mounted air conditioner indoor unit is specially designed for the shape of the air outlet of the shell, and the air outlet penetrates through the front side of the shell and the two transverse sides of the shell. Therefore, the air supply airflow can be blown forwards and can be blown to the left and right directions, 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. In addition, the invention also specially designs an outer air deflector with a special shape for the air outlet, the air deflector body of the outer air deflector corresponds to the air outlet at the front side of the shell, and the two end plate parts correspond to the air outlet at the two transverse sides of the shell, so the structure is very novel and ingenious.

Furthermore, in the wall-mounted air conditioner indoor unit, one or two end plate parts are provided with a plurality of first air dispersing holes so as to have a breeze effect. Specifically, when the air outlet was closed to outer aviation baffle, the air supply air current in the casing was blown to indoor environment through a plurality of first scattered wind holes, and the air supply air current is broken up, becomes softer, reaches a breeze effect, has promoted user experience.

Furthermore, in the wall-mounted air conditioner indoor unit, the bottom wall of the shell is also provided with the second air dispersing holes, so that the air supply mode of the air conditioner is more diversified, the selection of a user is enriched, and the user experience is improved.

Fig. 1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention; FIG. 2 is a left side partial schematic view of the air deflection plate of FIG. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 1 in a state where the air guide plate is opened.

As shown in fig. 1 to 3, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and an outer air guide plate 50. An air outlet 12 is formed on the housing 10, and the air outlet 12 penetrates through the front side and the lateral sides (lateral sides are labeled in the relevant figures) of the housing 10 to exhaust the air flow in the housing 10. The supply air flow is usually heat exchange air which exchanges heat with the heat exchanger. Of course, a fresh air stream is also possible.

The outer air guiding plate 50 is movably mounted on the housing 10. Specifically, as shown in fig. 1 to 3, the outer wind deflector 50 is rotatably mounted to the casing 10 around a direction parallel to the lateral direction of the casing 10. In addition, the outer air guiding plate 50 may also be telescopically mounted to the housing 10 so as to extend away from the air outlet 12 to open the air outlet 12. The outer air guiding plate 50 includes an air guiding plate body 51 and two end plates 52 extending from two transverse ends of the air guiding plate body 51 in a bending manner, and the air guiding plate body 51 and the two end plates 52 are respectively used for opening and closing the air outlet 12 at the front side and two transverse sides of the casing 10.

The wall-mounted air conditioning indoor unit according to the embodiment of the present invention is configured to have the shape of the outlet 12 of the casing 10, and the outlet 12 penetrates not only the front side of the casing 10 but also both lateral sides of the casing 10. Therefore, the air supply airflow can be blown forwards and can be blown to the left and right directions, 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. In addition, in the embodiment of the present invention, the outer air guiding plate 50 with a special shape is specially designed for the air outlet 12, the air guiding plate body 51 of the outer air guiding plate 50 corresponds to the air outlet 12 on the front side of the casing 10, and the two end plate parts 52 correspond to the air outlet 12 on the two lateral sides of the casing 10, so that the structure is novel and ingenious.

In some embodiments, as shown in fig. 2, one or both of the end plate portions 52 may be provided with a plurality of first air-dispersing holes 521 for discharging the air flow in the casing 10. Preferably, a plurality of first air-dispersing holes 521 are formed in both end plate portions 52. Therefore, the outer air guiding plate 50 can close the air outlet 12, so that the air flow in the casing 10 is blown to the indoor environment through the first air dispersing holes 521, and the air flow is dispersed and becomes softer, thereby achieving a breeze effect and improving the user experience. As shown in fig. 2, the first air-dispersing holes 521 may include a plurality of circular holes and a plurality of elliptical holes, and the air-out area of the elliptical holes is larger than that of the circular holes, so as to ensure a larger air-out amount, and avoid the influence on the cooling/heating speed due to the undersize air amount caused by the overall arrangement of the small circular holes.

Fig. 4 is a schematic bottom view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 5 is an enlarged view of fig. 4 at a.

In some embodiments, a plurality of second 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 second air-dispersing holes 13, thereby achieving large-air-volume cooling/heating. Alternatively, the air outlet 12 may be closed to supply air through the micro-holes only through the first air holes 521 and the second air holes 13, so as to achieve a completely non-wind-feeling air supply effect. In addition, the wall-mounted air conditioner indoor unit can supply air vertically downwards through the second 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, air is supplied vertically downwards through the second air dispersing holes 13, 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 second air dispersing holes 13 may be adjacent to the edge of the air outlet 12.

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 guiding plate 50 to close the air outlet 12, so that the air conditioner can completely supply air without wind sense through the first air dispersing holes 521 and the second air dispersing holes 13, and prevent cold air or hot air 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 second air dispersing holes 13 may be formed in a diamond shape as a whole. Compared with the conventional round micropores, the edges and corners of the diamond holes adopted by the invention are more distinct, and the scattering effect on airflow is stronger. Further, the plurality of second dissipating holes 13 may be arranged in a plurality of rows arranged in front and rear, and the second dissipating 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 second 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 of fig. 7 at B.

As shown in fig. 6 to 8, 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 second air dispersing holes 13 together with the bottom wall 101 of the casing 10.

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 second 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. 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 second 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 positions of the second air dispersing holes 13 can be effectively prevented by the stepped surface structure, and condensed water is prevented from dripping out through the second air dispersing holes 13.

In some embodiments, as shown in fig. 7-8, the flow guide 70 may be formed as a unitary 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 60. 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.

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.

A plurality of spherical recesses 61 are formed on both side surfaces of the inner air guiding plate 60. 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.

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