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.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is an enlarged sectional view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when a vertical baffle is used for guiding air at a large angle; fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when switching to the front blowing mode.

As shown in fig. 1 to 5, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10, a windshield 20, and a baffle 80.

The housing 10 is provided with an air outlet 12, and an upper end (a end) of the air outlet 12 is located above a lower end (b end) of the air outlet 12 and opens toward the front lower side. The cabinet 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The air outlet 12 may be opened at a lower portion of the front side of the casing 10. The outlet 12 is used for exhausting the airflow in the casing 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 the fan 40 in the cabinet 10 to accelerate the air flow flowing through the air outlet 12 for adjusting 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 casing 10 may be an elongated shape with a length direction (the transverse direction indicated in fig. 1) horizontally disposed, and the air outlet 12 may be an elongated shape with a length direction parallel to the length direction of the casing 10, as shown in fig. 1.

The windshield 20 is mounted to the housing 10 to be movable in an up-and-down translational motion between a raised position and a lowered position. The windshield 20 is located higher in the high-position state and lower in the low-position state. The windshield 20 includes a vertical baffle 21. When the windshield 20 is in a high position, the vertical baffle 21 is located at the front side of the air outlet 12 to shield the air outlet 12, as shown in fig. 2 to 4. The vertical baffle may be a vertically extending plate-like body. When the windshield 20 moves down to the low position, the front side of the outlet 12 is opened, as shown in fig. 5 and 6. Of course, the high position state and the low position state are only two limit states of the windshield 20 in the up-and-down reciprocating translation, and the windshield 20 may be in any state between the two states.

The guide plate 80 is rotatably disposed in front of the lower end of the air outlet 12, and is used for opening or blocking the air outlet 12 at the lower side of the air outlet 12, so that when the wind shield 20 is in a high position state, the guide plate 80 and the vertical baffle 21 together guide the air flow, as shown in fig. 2 to 4. When the wind shield 20 is in the low position, the guide plate 80 shields the air outlet 12 at the lower side of the air outlet 12 and guides the airflow forward, as shown in fig. 5 and 6. The wind shield 20 capable of moving up and down and the rotatable guide plate 80 are matched with each other, so that the air conditioner has two air outlet modes.

For example, when the air conditioner heats, the wind shield 20 can be in a high position and the air deflector 80 can open the lower side of the air outlet 12, so that the two cooperate to guide the air flow downward, so that the hot air can reach the ground more easily, thereby achieving a carpet type air supply effect, and avoiding that the indoor bottom space cannot be heated due to the fact that the hot air density is low and cannot reach the ground, as shown in fig. 2. When the air conditioner is refrigerating, the windshield 20 is in a low position to open the front side of the air outlet 12, and the deflector 80 shields the lower side of the air outlet 12 to guide the air flow to be blown out forward. Therefore, the cold air is blown farther and then gradually sinks, and the shower type refrigeration effect is formed. The embodiment of the utility model can select different air supply modes during refrigeration and heating, so that the air supply direction is more matched with different requirements of refrigeration and heating, and the design is very ingenious. When the air conditioner is in a non-operating state, the wind shield 20 is in a high position state and the guide plate 80 shields the lower side of the air outlet 12, so as to close the air outlet 12 together.

In some embodiments, the vertical baffle 21 includes an upper plate section 211 and a lower plate section 212 arranged above one another. The upper edge of the lower plate 212 is rotatably mounted on the upper plate 211, and the rotation axis y is parallel to the length direction of the casing 10, so that the wind guiding angle of the lower plate 212 is adjustable. The lower plate section 211 can be driven to rotate by a motor and can be kept at the rotated angle, and the specific driving structure is not described in detail.

When the windshield 20 is in the high position, the lower plate 212 can be rotated to adjust the air outlet direction and the size of the air outlet cross section, so as to further refine the air supply mode. Specifically, the lower segment 212 may be oriented in a vertical position to direct the airflow vertically downward, as shown in FIG. 2. Alternatively, the lower segment 212 may be rotated forward by a certain acute angle to guide the wind forward and downward, and the wind outlet cross section is larger and the wind volume is larger, as shown in fig. 3. Alternatively, the lower plate section 212 may be rotated to shield the lower side of the air outlet 12, so that the air flows out from the space between the lower end of the upper plate section 211 and the air guide plate 80. Of course, the plate section 212 may be rotated backward from the state of fig. 2 to make the outlet cross section smaller.

As shown in fig. 2, 3 and 4, when the windshield 20 is in the high position, the deflector 80 and the lower segment 212 may be kept at an angle parallel or substantially parallel to each other, so as to enhance the guiding function of the wind direction. In some embodiments, the axis of rotation z of the deflector 80 is located above the rear end of its plate, adjacent to the lower end of the outlet mouth 12. So set up, when making baffle 80 rotate to the state of standing up (refer to fig. 2), be closer to the lower extreme of air outlet 12 to make the air current all flow out from between lower plate section 212 and baffle 80, accept more powerful guide. When in a horizontal state, the rear end of the air outlet is just connected with the lower end of the air outlet.

In some embodiments, as shown in fig. 2 to 6, the casing 10 has an air duct 50 therein, and the air duct 50 is defined by a front air duct wall 200 and a rear air duct wall 100 which are spaced apart from each other in the front-rear direction. The outlet ends of the front duct wall 200 and the rear duct wall 100 are respectively connected to the upper end and the lower end of the air outlet 12, so as to guide the air flow in the cabinet 10 to the air outlet 12. An air inlet 11 is formed at the top of the casing 10, and a cross flow fan 40 having an axis extending in a transverse direction is disposed at an inlet of the air duct 50. The three-stage heat exchanger 60 surrounds the crossflow blower 40. When the wall-mounted air conditioner indoor unit operates in a cooling mode or a heating mode, indoor air enters the interior of the casing 10 through the air inlet 11, exchanges heat with the three-section heat exchanger 60, is finally sucked into the air duct 50 by the cross-flow fan 40, and flows towards the air outlet 12.

When the air guide plate 80 is in a state of shielding the air outlet 12, the rear end thereof is lapped on the inner surface of the rear air duct wall 100. Further, as shown in fig. 5, a section of the rear air duct wall 100 adjacent to the air outlet 12 is formed with a downward concave portion 110 recessed downward to accommodate the rear end of the air deflector 80 when the air deflector 80 is in a state of shielding the air outlet 12, so as to avoid air flow loss caused by the air deflector 80 protruding from the inner surface of the rear air duct wall 100.

As shown in fig. 1 and 2, when the windshield 20 is in the high position, the front surface of the upper plate 211 is flush with the front surface of the casing 10, so that the windshield 20 and the casing 10 form a complete abutting appearance effect. And the lower plate 212 is configured to be rotatable to a position where the front surface thereof is flush with the front surface of the upper plate 211, as shown in fig. 2, when the wall-mounted air conditioner indoor unit is in a non-operating state, the windshield 20 can be in a high position, and the lower plate 212 is in the aforementioned flush position, so that the appearance of the air conditioner is more complete and beautiful.

Fig. 6 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 5 after the air deflector is rotated to another angle, and fig. 7 is an enlarged view of the air deflector of fig. 5.

In some embodiments, the wall-mounted air conditioning indoor unit further includes a wind deflector 30. As shown in fig. 7, the air deflection plate 30 includes a swing arm 32 and a plate body 31. The plate 31 is elongated with its longitudinal direction parallel to the longitudinal direction of the housing 10, and its rotation axis x is parallel to its longitudinal direction. The number of swing arms 32 may be two or more. A first end of the swing arm 32 is rotatably connected to the cabinet 10, and a second end of the swing arm 32 is connected to the plate body 31. When the air deflector 30 is in a position such that the second end is directly below the first end, the front section of the plate body 31 is in a raised shape that gradually slopes upward from a rearward front curve. When the air deflector 30 is in a position where the second end (of the swing arm 32) is located directly below the first end (of the swing arm 32), or when the swing arm 32 is in a vertically extended state, the upward surface of the plate body 31 is the first side 311, and the downward surface is the second side 312.

The air deflector 30 is configured to rotate to a lower end near the air outlet 12, and to make the first side 311 face upward to an upward air guiding position, as shown in fig. 5; or rotate to a downward wind guiding position adjacent to the upper end of the wind outlet 12 and make the first side 311 face downward and rearward, as shown in fig. 2, 3, 4 and 6. Specifically, the above-mentioned effect can be achieved by positioning the rotation axis x of the air deflector 30 between the upper end and the lower end of the air outlet 12. When the air deflector 30 is in the upward air guiding position, the plate 31 guides the airflow to flow upward, so that the upward angle of the airflow in the cooling forward blowing mode is larger, as shown in fig. 5. When the air deflector 30 is in the lower air guiding position, the plate body 31 is more tangent to the front air duct wall 200, so as to reduce the wind resistance when the air flow flows to the air deflector 30, as shown in fig. 2, so that the forward-blowing air flow changes direction more smoothly, flows to the vertical baffle 21 with less resistance, and is guided downwards by the vertical baffle 21. Of course, when the windshield 20 is in the low position, the air deflector 30 may be in the downward air guiding position to guide the air flow forward and downward.

As shown in fig. 7, the first side surface 311 includes a first straight line segment AB, a first arc segment BC, a second arc segment CD and a third arc segment DE, which are sequentially connected from back to front, and each arc segment has a concave side facing outward. The second side 312 includes a second straight section FG, a fourth curved section GH, and a fifth curved section HK, which are connected in sequence from back to front, and each of which has a convex side facing outward. Thus, the transition between the straight line section at the rear part and the raised section at the front part of the plate body 31 is more gradual, and the line type of the first side surface 311 and the second side surface 312 is more reasonable, so that the flow resistance of the air flow is smaller.

Further, the ratio of the radius of the second arc segment CD to the radius of the first arc segment BC is between 0.6 and 0.8, preferably between 0.5 and 0.7. The ratio of the radii of the third curved section DE to the first curved section BC is between 2.6 and 3.0, preferably between 2.7 and 2.9. The ratio of the radii of the fourth arcuate section GH to the fifth arcuate section HK is between 2.6 and 3.0, preferably between 2.7 and 2.9. As shown in fig. 7, when the air guide plate 30 is positioned such that the second end of the swing arm 32 is positioned directly below the first end of the swing arm 32, the ratio of the front-rear end pitch (the linear distance between K and F) of the plate 31 to the pitch (the distance between K1 and F) projected on the horizontal plane between the front-rear end pitch and the pitch (the linear distance between K and F) is 1.03 to 1.11. Through the design, the line type of the first side 311 and the second side 312 is more reasonable, so that the flow resistance of the airflow is smaller.

Fig. 8 is a schematic view showing a structure of a windshield of the wall-mounted air conditioning indoor unit shown in fig. 1.

In some embodiments, as shown in fig. 1 to 8, the windshield 20 further includes two side plates 22 respectively connected to two lateral ends of the upper plate section 211, and the two side plates 22 are respectively configured to be mounted on two lateral sides of the casing 10 in a vertically-movable manner. The provision of the two side plates 22 provides a more aesthetic appearance to both sides of the windshield 20 and facilitates the provision of the connecting and driving structure at the lateral ends of the casing 10. In a high position, the upper end of the vertical baffle 21 abuts against the upper end of the air outlet 12, and the outer surfaces of the vertical baffle 21 and the two side plates 22 are flush with the outer surface of the casing 10, so that the windshield 20 and the casing 10 form a complete butt joint appearance effect. When the wall-mounted air conditioning indoor unit is in the non-operating state, the windshield 20 can be in this state, so that the appearance is more beautiful.

The windshield 20 also includes a base plate 23. The two lateral sides of the bottom plate 23 are connected to the two side plates 22 respectively and are located below the bottom wall of the casing 10. Thus, the bottom of the windshield 20 has a more complete and beautiful appearance. The bottom plate 23 is opened with an air outlet 230 opposite to the air outlet 12 to allow the air flow to flow out downwards. That is, the air flow inside the casing 10 flows through the air outlet 12 and then blows to the indoor environment through the air outlet 230. The vertical baffle 21, the bottom plate 23 and the two side plates 22 constitute an integral piece.

When the windshield 20 is in a high position, the outer surfaces of the upper plate section 211 and the two side plates 22 are flush with the outer surface of the casing 10, so that the windshield 20 and the casing 10 form a complete butt joint appearance effect. When the wall-mounted air conditioning indoor unit is in the non-operating state, the windshield 20 can be in this state, so that the appearance is more beautiful.

In some embodiments, the wall-mounted air conditioning indoor unit utilizes a rack and pinion mechanism to drive the windshield 20 to translate up and down. As shown in fig. 9, the casing 10 has mounting plates 13 at two lateral ends, and the mounting plates 13 are provided with rack and pinion mechanisms for driving the windshield 20 to move up and down. The mounting plate 13 has a plurality of lugs 132 for attachment to the end caps of the cabinet 10 by screws. The rack and pinion mechanism includes a motor 71, a gear 72 and a rack 73 that engage with each other. The motor 71 is disposed inside the mounting plate 13, the gear 72 is mounted on the motor 71, and the rack 73 is disposed inside the mounting plate 13 so as to be vertically translatable. A part of the rack 73 extends out of the mounting plate 13 through a vertical long-strip abdicating hole formed in the mounting plate 13, and is connected with the side plate 22 of the windshield 20.

When the motor 71 drives the gear 72 to rotate, the gear 72 drives the rack 73 to move up and down, so as to drive the windshield 20 to move up and down.

In the embodiment, the main structure of the rack-and-pinion mechanism is installed at the lateral side end of the casing 10, so that the appearance of the wall-mounted air conditioner indoor unit is not affected.

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.
