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 4, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10, a first air deflector 50, a second air deflector 60, and a baffle 70.

The housing 10 is opened with an air outlet 12 opened forward and downward. 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 (perpendicular to the paper surface of fig. 1) horizontally disposed, and the outlet 12 may be a long strip with a length direction parallel to the length direction of the housing 10, and the length direction is perpendicular to the paper surface of fig. 1.

The wall-mounted air conditioner indoor unit may be an indoor part of a split wall-mounted type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. As shown in fig. 1, the inside of the case 10 is provided with 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.

The first air deflector 50 is swingably mounted on the front side of the outlet 12, and the swing axis x is located at the upper end of the outlet 12 and is used for opening or shielding the front space of the outlet 12. The swing axis x may be made parallel to the longitudinal direction of the housing 10.

The second air deflector 60 and the baffle 70 are used to cooperatively open or shield the lower space of the outlet 12, the second air deflector 60 is rotatably installed at the lower side of the outlet 12, and the baffle 70 is telescopically installed at the housing 10 in a front-back direction to protrude forward (refer to fig. 1 and 2) or retract backward (refer to fig. 3 and 4) from the lower end of the outlet 12. For example, the baffle 70 may be provided on the inner surface of the bottom wall of the housing 10 so as to be translatable back and forth.

In the embodiment of the present invention, the first air deflector 50, the second air deflector 60, and the baffle 70 are disposed at the air outlet 12, so that the air outlet 12 can realize the blowing of cold air and the blowing of hot air by blowing upward and downward through the cooperation of the three, and the adjustment modes of the air output and the air output direction are very diversified.

The wall-mounted air conditioning indoor unit can operate in a wind-up mode, as shown in fig. 2. The first air guiding plate 50 is turned upwards to completely avoid the front side of the air outlet 12, and the second air guiding plate 60 is rotated to an angle inclined upwards to guide air upwards, so that the baffle 70 is in an extended state. When the air conditioner is used for refrigerating, the air conditioner can be used for raising and sending air so as to enable the air to be scattered downwards after reaching the highest point, a bathing type refrigerating effect is formed, and discomfort caused by direct blowing of cold air to a human body is avoided.

The wall-mounted air conditioning room can also run in a sink blowing mode, as shown in fig. 3. The first air guiding plate 50 is swung to the shielding state to prevent the blowing air from blowing forward, so that the uncovered portion of the air outlet 12 is opened downward. Meanwhile, the second wind guide plate 60 can be rotated to a vertically extended state to guide wind downward better. The baffle 70 can be retracted as shown in fig. 3 to maximize the air outlet area of the air outlet 12. Of course, the baffle 70 may also be extended to reduce the air outlet area of the air outlet 12. When the air conditioner is used for heating, the air conditioner can sink for air supply, so that hot air flows upwards after sinking to the ground, a carpet type heating effect is formed, and the poor heating effect at the bottom of an indoor space is avoided.

The wall-mounted air conditioning room can also run in a maximum blowing mode, as shown in fig. 4. The first air guiding plate 50 is opened to the front space of the air outlet 12, and the baffle 70 is retracted to open the air outlet 12 to the maximum extent. The second air deflector 60 is rotated to be gradually inclined downwards from back to front, and the width direction of the second air deflector is just along the airflow direction, so that the resistance of the second air deflector to the airflow is minimum, the air outlet is most smooth, and the air volume is maximum.

The air supply mode of the embodiment of the utility model is very diversified, and the raising and sinking effects are better. Firstly, because two air deflectors and a baffle are arranged, the upper end of the air outlet 12 can be designed to be closer to the upper part, and the lower end of the air outlet 12 can be designed to be closer to the rear part, so that the air outlet 12 is larger, and the air supply angle can be enlarged. Secondly, since the swing axis x of the first air guiding plate 50 is disposed at the upper end of the air outlet 12, the first air guiding plate 50 can be turned upwards to completely avoid the front side of the air outlet 12, so as not to block the rising air flow. The design of the baffle 70 enriches the air supply mode, and the air outlet area of the air outlet 12 can be changed through the extension of the baffle 70, so that the air output is adjusted.

In some embodiments, as shown in fig. 1, a wall-mounted air conditioning indoor unit is configured to: when the first air guiding plate 50 and the second air guiding plate 60 are both in the shielding state and the baffle 70 is in the extending state, the ends of the three plates are adjacent to each other to close the air outlet 12. The adjacent is the maximum approach, but a small distance is required to be kept to ensure that the second wind deflector 60 can rotate freely without interference of the first wind deflector 50 when the first wind deflector 50 is in a shielding state. Specifically, the lower end of the first air guiding plate 50 is adjacent to the front end of the second air guiding plate 60, and the rear end of the second air guiding plate 60 is adjacent to the front end of the baffle plate 70.

Further, as shown in fig. 1, when the two air deflectors and the baffle are both located at a position for closing the air outlet 12, the front end of the second air deflector 60 is close to the bottom of the rear surface of the first air deflector 50, and the lower surface of the second air deflector 60 is flush with the lower surface of the baffle 70, so that the three are completely spliced, and the appearance of the wall-mounted air conditioning indoor unit is more attractive.

In some embodiments, when the baffle 70 and the second air deflector 60 are both in the position for closing the air outlet 12, the front end of the baffle 70 faces the rear end of the second air deflector 60, as shown in fig. 1. And, after the second air deflector 60 is rotated away from the closed position (see fig. 2), the baffle 70 can be moved forward. That is, the baffle 70 can not only be moved forward to the position of fig. 2, but can also be moved forward further on the basis of fig. 2. In this way, in the upward blowing mode, the airflow on the upper surface of the baffle plate 70 flows to the upper surface of the second air guiding plate 60, so that the airflow is reduced from flowing downward between the baffle plate 70 and the second air guiding plate 60, and the airflow is blown upward more.

The rotatable range of the second air deflector 60 can be made to be larger than 360 degrees, so that the second air deflector can rotate to any angle to guide air better, and the surfaces of the second air deflector 60 can be alternately subjected to air by changing the angle position of the second air deflector 60 at regular time, so that the generation of surface condensation is avoided. The rotation axis y of the second air guiding plate 60 may be located at the center portion in the width direction thereof to achieve the above-described function.

Fig. 5 is a schematic view of a damper driving mechanism in a wall-mounted air conditioning indoor unit according to an embodiment of the present invention; fig. 6 is an enlarged view of fig. 5 at a.

In some embodiments, as shown in fig. 5 and 6, the wall-mounted air conditioning indoor unit further includes a rack 83, a gear 82, and a motor 81. The rack 83 extends in the front-rear direction and is provided on the shutter 70. The gear 82 engages the rack 83 to cause the rack 83 to translate back and forth when rotated, thereby causing the flapper 70 to translate back and forth. The rack 83 may be integrally formed with the baffle 70. A motor 81 is installed in the housing 10 for driving the gear 82 to rotate. The motor 81 may be a stepping motor capable of rotating forward and backward. In alternative embodiments, other means of driving the shutter 70 back and forth in translation may be utilized, such as a linear motor.

FIG. 7 is a schematic view of an embodiment of the present invention. The first air deflection plate 50, the second air deflection plate 60, and the baffle plate 70 are omitted from fig. 7.

In some embodiments, as shown in fig. 1 and 7, a wind tunnel 20 is provided within the housing 10. The duct 20 is defined by front and rear duct walls 200, 100 spaced apart from one another. 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 casing 10 to the air outlet 12, and blow the air flow to the indoor environment through the air outlet 12, thereby completing air conditioning of the indoor environment, such as cooling and heating.

As shown in fig. 7, the 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. Because the outlet section of the front air duct wall 200 adopts the above shape, when the air outlet 12 is blown out towards the front upper side (for example, in a refrigeration mode), the air flow gradually rises 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, and when the air conditioner is refrigerated and blown up, the rising angle of the air flow is favorably improved, so that cold air is 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, and the cold air is scattered downwards after reaching the highest point, thereby realizing the 'shower type' refrigeration experience.

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. 7, 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. 7. 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. 7, the rear duct wall 100 includes a main body segment AB and a forward 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 encloses 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.
