The embodiment of the utility model provides a wall-mounted air conditioner indoor unit. 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 6, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a case 10, a breeze guard 50, and a wind deflector 60.

Wherein, the housing 10 is provided with an air outlet 12 opening towards the front lower part. The casing 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The outlet 12 may be opened at a lower portion of the front side of the housing 10 so as to be open toward the front lower side. The outlet 12 is used to discharge the airflow in the housing 10 to the indoor environment to condition the indoor air. The discharged air flow is referred to as air flow which is acted on by a fan in the housing 10 to accelerate the air flow passing through the air outlet 12 for conditioning the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, fresh air in a fresh air mode, and the like. The housing 10 may be a long strip with a length direction horizontally arranged, and the air outlet 12 may be a long strip with a length direction parallel to the length direction of the housing 10, where the length direction of the housing 10 is perpendicular to the paper surface of fig. 1.

The breeze baffle 50 is disposed in front of the outlet 12, and has a plurality of air-dispersing micro holes 51 penetrating through the breeze baffle 50 in the thickness direction. The air deflector 60 is rotatably disposed at the lower side of the air outlet 12 for guiding the air outlet direction or closing the air outlet 12 together with the breeze baffle 50. Each of the air dispersing minute holes 51 of the breeze guard 50 may be a circular hole, as shown in fig. 2. The air dispersing micropores 51 may also be elongated holes, as shown in fig. 3. Of course, the air dispersing micro holes 51 may be holes of other shapes.

When the breeze baffle 50 is located at the position where the front side of the air outlet 12 is closed, the airflow in the housing 10 is blown into the room through the breeze baffle 50, and the airflow is broken up, so that the breeze is softer and more comfortable. The conventional air deflector 60 is disposed at the lower side of the air outlet 12, and can guide the air outlet direction and close the air outlet 12 together with the breeze baffle 50. Namely, the air conditioner can operate a conventional air outlet mode and a breeze mode, and the air supply function is enriched.

The wall-mounted air conditioner indoor unit of the embodiment of the utility model can be an indoor part of a split wall-mounted room air conditioner which utilizes a vapor compression refrigeration cycle system to carry out refrigeration/heating. As shown in fig. 1, the casing 10 is provided inside with an air duct 20, a heat exchanger 30, and a fan 40. The heat exchanger 30, the throttling device and a compressor, a condenser and other refrigeration elements arranged in the air-conditioning outdoor shell are connected through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the inside of the housing 10 through the air inlet 11 at the top of the housing 10, and after completing the forced convection heat exchange with the heat exchanger 30, forms heat exchange air, and then blows toward the air outlet 12 under the guidance of the air duct 20. The fan 40 is preferably a cross flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 20. The heat exchanger 30 may be a three-stage heat exchanger.

In the first embodiment of the present invention, as shown in fig. 2 to 6, the breeze baffle 50 can be rotatably installed on the housing 10 to guide the wind direction. Two motors are installed in the casing 10 for driving the rotation of the breeze baffle 50 and the air deflector 60, respectively. The breeze damper 50 is rotatably attached to the casing 10, and also has a wind guide function, and can guide wind forward upward, forward, or downward.

When the air conditioner is not operating, the breeze flap 50 can be rotated to a closed position at or near the vertical extension and the air deflector 60 can be rotated to a closed position at or near the horizontal extension, as shown in fig. 1. When the air conditioner needs to be in the top blow molding mode (e.g., cooling mode), the breeze guard 50 may be rotated to a state of gradually inclining upward from the rear to the front, and the air guide 60 may be rotated to a closed state, as shown in fig. 4, to guide the air flow to the front and upper side. When the air conditioner needs to be in a lower blow molding mode (e.g., a heating mode), the breeze flap 50 may be rotated to a closed state, and the air guide plate 60 may be rotated to a vertically extended state to guide the air flow to a right lower side, as shown in fig. 5. When the air conditioner needs to accelerate the air conditioning speed, the maximum air outlet mode can be operated, that is, the breeze baffle 50 and the air deflector 60 are rotated to be in a state of gradually inclining downwards from back to front, and the breeze baffle 50 and the air deflector are parallel or nearly parallel, so that the air outlet is most smooth, and the air volume is maximum, as shown in fig. 6.

In this embodiment, the breeze baffle 50 is arranged to shield the air outlet 12 at the front side of the air outlet 12, so that the upper edge of the air outlet 12 can be designed to be more upward, and the wind can be guided upwards at a larger uplifting angle (the upper edge of the air outlet 12 is closer to the upper side, and the theoretical maximum uplifting angle is larger). Moreover, the air outlet area of the air outlet 12 is larger, so that the air outlet is smoother, the wind resistance is reduced, and the large-air-volume air supply is facilitated.

In some embodiments, as shown in fig. 1 to 6, the casing 10 in the wall-mounted air conditioning indoor unit includes a connection portion 15. The connecting portion 15 is configured to divide the outlet 12 into a front outlet 121 located above the connecting portion 15 and a lower outlet 122 located behind the connecting portion 15. Therefore, the air outlet of different air outlet modes can be conveniently controlled. Specifically, referring to fig. 1, the duct 20 includes a front duct wall 200 and a rear duct wall 100 that are disposed at an interval, and the connecting portion 15 is located right below the front end of the front duct wall 200 and right in front of the lower end of the rear duct wall 100. The length direction of the connecting portion 15 is parallel to the transverse direction of the housing 10, and both ends of the connecting portion are respectively connected with the main body portion of the housing 10, or an integrally molded structure. The outer contour of the connecting portion 15 may further include a front surface 151 facing forward, a lower surface 152 facing downward, and an arc-shaped wind guiding surface 153 facing the inside of the housing 10 and protruding outward. When preceding air outlet 121 goes out wind, arc air guide surface 153 can guide the air current to the front upper side, and when lower air outlet 122 goes out wind, arc air guide surface 153 can guide the air current downwards, and the design is very ingenious.

Fig. 7 is a schematic view of a wall-mounted air conditioning indoor unit according to a second embodiment of the present invention, in which a breeze guard is closed.

In the second embodiment of the present invention, as shown in fig. 7, the air outlet 12 is an integral air outlet, and no connection portion is provided, when the breeze baffle 50 and the air deflector 60 are both in the closed state, the lower end of the breeze baffle 50 is close to the front end of the air deflector 60, so that the structure of the wall-mounted air conditioner indoor unit is simpler. Moreover, because there is no blocking of the connecting part, the air outlet of the air outlet 12 is smoother. In some embodiments, as shown in fig. 1 and 7, the breeze guard 50 has its pivot axis x located behind the center of its plate when in the closed state. When the air deflector 60 is in the closed state, the pivot axis y thereof is located above the front of the plate body thereof. By such design, the breeze baffle 50 and the air deflector 60 can smoothly rotate to the above-mentioned up-blowing, down-blowing and maximum air-out states without interference.

Fig. 8 is a schematic view of a wall-mounted air conditioning indoor unit according to a third embodiment of the present invention.

As shown in fig. 8, in the third embodiment of the present invention, the breeze baffle 50 is fixed to the case 10 in an upright position. That is, the breeze blocking plate 50 is always in a state of shielding the front side of the outlet 12, and the air guide plate 60 guides the air outlet direction of the outlet 12. The air deflector 60 is used for guiding the air flow from the lower side of the air outlet 12 forward downward or right downward.

As shown in fig. 8, at least part of the air dispersing micropores 51 of the breeze guard 50 are configured to guide the airflow at the air outlet 12 toward the front.

Fig. 9 is a schematic view of a wall-mounted type air conditioner indoor unit according to a fourth embodiment of the present invention; fig. 10 is a partial structural view of the breeze guard 50 of fig. 9.

The fourth embodiment of the present invention is different from the third embodiment in that at least part of the air dispersing microholes 51 of the breeze guard 50 are configured to guide the airflow at the air outlet 12 toward the front upper side. Therefore, the breeze baffle 50 always blows air forward and upward, the air supply distance is increased, and the scheme does not need to move the breeze baffle 50 and arrange a driving mechanism.

For example, as shown in fig. 9 and 10, the breeze guard 50 is formed in a grid shape, and the spaces between the adjacent grid bars 52 form the fine air dispersing holes 51. Each of the grille strips 52 extends gradually upward from the front so that the air-dispersing micropores 51 are also inclined upward, thereby guiding the airflow upward.

The fourth embodiment of the present invention is different from the third embodiment in that at least part of the air dispersing microholes 51 of the breeze guard 50 are configured to guide the airflow at the outlet 12 toward the front.

In the embodiment shown in fig. 8 and 9, the breeze guard 50 may be integrally formed with the front panel of the housing 10 to simplify the assembly process.

FIG. 11 is a schematic view of an embodiment of the present invention. Fig. 11 is a more clear illustration of the air duct structure, and omits the structures such as the breeze baffle 50 and the air deflector 60.

As shown in fig. 11, the air duct 20 according to the embodiment of the present invention is disposed in the casing 10, and includes a front air duct wall 200 and a rear air duct wall 100 that are disposed at a distance from each other in the front-rear direction, and outlet ends of the front air duct wall 200 and the rear air duct wall 100 are respectively connected to an upper end and a lower end of the air outlet 12, so as to guide an air flow in the casing 10 to the air outlet 12, and blow the air flow to an indoor environment through the air outlet 12, thereby completing air conditioning of the indoor environment, such as cooling and heating.

As shown in fig. 11, a section of the front duct wall 200 adjacent to the outlet end thereof is curved to be convex downward, and an outlet end tangent line C1 extends upward and forward. Moreover, the section of the rear air duct wall 100 near the outlet end thereof is curved to protrude forward, and the outlet end tangent line C2 extends forward downward or directly downward.

According to the coanda effect, when there is surface friction (also called fluid viscosity) between a fluid and the surface of an object over which it flows, the fluid follows the surface of the object as long as the curvature is not large. Due to the fact that the shape is adopted in the outlet section of the front air duct wall 200, when the air outlet 12 is used for air to flow towards the front upper side (for example, in a refrigeration mode), the air flow gradually rises when flowing forwards along the surface of the front air duct wall 200 under the action of the coanda effect, the rising angle of the air flow is larger, when the air conditioner is used for refrigerating and blowing upwards, the rising angle of the air flow is improved, cold air can be blown out at the larger rising angle (the included angle between the air flow blowing angle and the horizontal plane) to avoid a human body, the cold air is scattered downwards after reaching the highest point, and the 'shower type' refrigeration experience is achieved.

Similarly, since the section of the rear duct wall 100 of the duct 20 near the outlet end is curved protruding forward, and the tangent of the outlet end extends forward or downward, when the air outlet 12 supplies air downward (for example, in a heating mode), the air flow gradually inclines downward along the surface of the rear duct wall 100, so that the air flow outlet direction is closer to or reaches a vertical downward direction, and reaches the ground more, thereby achieving a "carpet" air supply effect.

Specifically, as shown in fig. 11, the front duct wall 200 includes a volute tongue section EF, a connecting section FG, and a lower convex line section GJ. The front end of the volute tongue section EF constitutes the inlet end of the front duct wall 200, and extends from the front upper side to the rear lower side. The volute tongue section EF is opposite the fan 40. The connecting section FG extends forward and downward from the rear end of the volute tongue section EF. The lower arc line segment GJ extends forward from the rear end of the connecting segment FG, and is an arc that is convex downward (i.e., the axis of the arc is located above it), the axis of the arc being parallel to the lateral direction of the air outlet 12. The lateral direction of the outlet port 12 refers to the lateral direction of the housing 10, that is, the direction perpendicular to the paper surface in fig. 11. The front end of the lower arcuate line segment GJ constitutes the outlet end of the front duct wall 200 and the tangent C1 extends upward and forward. The adjacent sections can adopt fillet transition to reduce the resistance loss of the airflow, make the airflow steering more smooth and facilitate the wall attachment effect of the airflow. The connecting section FG can be a straight line section, and the value range of the included angle theta between the connecting section FG and the horizontal direction is more than or equal to 20 degrees and less than or equal to 30 degrees, so that the turning angle between the connecting section FG and the lower arc line section GJ is most reasonable, and the phenomenon that the airflow is far away from the surface of the lower arc line section GJ due to the fact that the turning angle is too large is avoided. The radius value range of the lower arc line segment GJ is preferably more than or equal to 100mm and less than or equal to 300mm, so that the airflow attachment effect is enhanced, and the phenomenon that the airflow is far away from the surface of the lower arc line segment GJ due to the overlarge turning angle is avoided.

As shown in fig. 11, the rear duct wall 100 includes a main body segment AB and a front convex arc segment BC. Wherein the main body section AB is in the shape of an arc projecting rearward, the upper end of which constitutes the inlet end of the rear duct wall 100. The main section AB surrounds the fan 40 in half on its rear side. The front convex arc segment BC extends obliquely from the lower end of the main body segment AB toward the front lower side, and is an arc shape protruding forward, and the lower end thereof constitutes the outlet end of the rear duct wall 100 and the tangent C2 extends toward the front lower side. The arc axes of the main body segment AB and the front convex arc segment BC are both parallel to the transverse direction of the air outlet 12.

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