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 switching to the front blowing mode.

As shown in fig. 1 to 3, a wall-mounted indoor unit of an air conditioner according to an embodiment of the present invention may generally include a cabinet 10 and a windshield 20.

The casing 10 is provided with an air outlet 12 opened forward and downward. The cabinet 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 a front side of the cabinet 10 so as to be opened toward a front lower side. 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 on the housing 10 to be vertically movable, and the windshield 20 includes a vertical baffle 21 for shielding the air outlet 12 at the front side of the air outlet 12. The windshield 20 is configured to translate up and down between a blow-down configuration and a blow-forward configuration. When the wind shield 20 is in the down-blowing state, the vertical baffle 21 is located at the front side of the air outlet to shield the air outlet 12, and guides the air flow to flow downward, so that the air flow in the casing 10 cannot be blown out forward, as shown in fig. 2. When the windshield 20 is in the forward blowing state, the upper end of the vertical baffle 21 is spaced from the upper end of the air outlet 12, allowing the airflow to flow forward. That is, the vertical baffle 21 is far away from the front side of the outlet 12 so as not to obstruct the outlet airflow from blowing out forward or upward as shown in fig. 3. Of course, the down-blowing state and the forward-blowing state are only two limit states of the up-down reciprocal translation of the windshield 20, and the windshield 20 may be in any state therebetween.

The down blowing mode can be selected when the air conditioner heats, so that hot air can reach the ground more easily, the carpet type air supply effect is realized, and the problem that the indoor bottom space cannot be heated due to low hot air density is avoided. The air conditioner can select a forward blowing mode during refrigeration, so that the air supply distance of cold air is longer, and then the cold air gradually sinks to form a shower type refrigeration effect.

The wall-mounted air conditioner indoor unit provided by 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 the special requirements of refrigeration and heating, and the design is very ingenious.

In some embodiments, as shown in fig. 1 to 3, the wall-mounted air conditioning indoor unit further includes a wind deflector 30. The air guide plate 30 is rotatably installed at the cabinet 10 and located behind the vertical baffle 21. Specifically, the air guiding plate 30 is elongated with a length direction parallel to the length direction of the casing 10, and the rotation axis x is parallel to the length direction. The air deflection plate 30 is configured to be rotatable between a down-draft condition and a forward-draft condition. In the downward air guiding state, the air guiding plate 30 is located at the front side of the air outlet 12 to guide the airflow to flow downward, as shown in fig. 2; in the front wind guiding state, the wind deflector 30 is located at the lower side of the wind outlet 12 to guide the airflow to flow forward. Of course, the downward wind guiding state and the forward wind guiding state are only two extreme angle positions of the wind deflector 30, and the wind deflector 30 may be in any state between the two. The driving motor can be used to drive the air deflector 30 to rotate.

In this embodiment, the air deflector 30 has a front air guiding mode and a lower air guiding mode, and the cooperation between the air deflector 30 and the windshield 20 realizes better upward blowing and forward blowing effects, and reduces the loss of air flow. Specifically, in the down-blowing mode, the air flow is guided downwards by the air deflector 30, so that the air flow is prevented from directly impacting the vertical baffle 21 at an angle close to a right angle, and the flow loss of the air flow can be reduced, as shown in fig. 2. In the forward blowing mode, the air flow is guided forward by the air deflector 30, so that the downward flow of the air flow can be avoided or avoided as much as possible, and the air flow can be blown forward more, as shown in fig. 3.

Fig. 4 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a state switched between a front blowing mode and a lower blow molding mode; fig. 5 is a schematic view showing a configuration of the wall-mounted air conditioning indoor unit shown in fig. 2 when the windshield is switched to the forward blowing state.

In addition, in the embodiment of the present invention, the wall-mounted air conditioning indoor unit does not have only the down-blowing mode and the down-blowing mode shown in fig. 2 and 3, but also has other diversified air blowing modes.

For example, as shown in fig. 4, the windshield 20 may be in a state between a down-blowing state and a forward-blowing state, and the air deflector 30 may be in a state between a down-guiding state and a forward-guiding state, so that the air flow at the air outlet 12 is blown out forward and downward at the same time, and the air supply angle range of the entire air conditioner is widened.

For example, as shown in fig. 5, the air deflector 30 and the windshield 20 are configured such that: when the windshield 20 is in a down-blowing state and the air deflector 30 is in a down-blowing state, the air deflector 30 guides the airflow to flow downward from the inner side and the outer side of the vertical baffle 21, so that the down-blowing air volume is larger.

In some embodiments, as shown in fig. 2 and 3, 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.

In the downward wind guiding state, one end of the wind deflector 30 abuts against the front air duct wall 200, so that the airflow flowing along the front air duct wall 200 can be better transferred onto the wind deflector 30, and the flow loss of the airflow is reduced by receiving the guidance of the wind deflector 30. In the front wind guiding state. The other end of the air deflector 30 abuts against the lower end of the air outlet 12, so that the airflow flowing along the rear air duct wall 100 can better transit to the air deflector 30, and is guided by the air deflector 30, and the flow loss of the airflow is reduced.

In some embodiments, as shown in fig. 3, the upper surface of the air deflector 30 in the forward blowing state is arc-shaped, and the tangent line of the front end of the arc is forward and upward, so as to guide the airflow to flow upward, which is beneficial to improving the upward angle of the airflow, so as to blow out cold air at a larger upward angle (the included angle between the airflow blowing angle and the horizontal plane) to avoid the human body, and the cold air is scattered downward after reaching the highest point, thereby realizing the shower type refrigeration experience.

Fig. 6 is a schematic structural view of the windshield 20 in fig. 1.

In some embodiments, as shown in fig. 1 to 6, the windshield 20 further includes two side plates 22 extending rearward from two lateral ends of the vertical baffle 21, and the two side plates 22 are respectively configured to be mounted on two lateral sides of the casing 10 in a vertically translatable manner. The two side plates 22 are provided to make both sides of the windshield 20 more beautiful in appearance and facilitate the arrangement of the connecting and driving structure at the lateral end of the casing 10. In the down-blowing state, 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 in the casing 10 flows downward, and needs to flow through the air outlet 12 and then blow toward 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.

Fig. 7 is a schematic view of a mechanism for driving the windshield 20 and the air guide plate 30 of the wall-mounted air conditioning indoor unit. Fig. 8 is another angular schematic of fig. 7.

In some embodiments, the wall-mounted air conditioning indoor unit utilizes a rack and pinion mechanism to drive the windshield 20 in an up and down translation. As shown in fig. 7 and 8, the casing 10 has mounting plates 13 at two lateral ends, and the mounting plates 13 are provided with a rack and pinion mechanism 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, the rack 73 is disposed inside the mounting plate 13 in a vertically movable manner, and a portion of the rack extends out of the mounting plate 13 through a long vertical receding hole 131 formed in the mounting plate 13 and is connected to 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.
