Fig. 1 is a schematic structural view showing a closed air guide 50 and a closed air guide 60 of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, as shown in fig. 1, and referring to fig. 2 to 17, an embodiment of the present invention provides a wall-mounted air conditioner indoor unit, including a casing 10 and an air guide 50. The housing 10 has an air outlet 40 facing forward and downward, and in the above-mentioned figure, the dotted line position is the position of the air outlet 40. The casing 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The airflow within the housing 10 is exhausted 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 30 in the housing 10 to accelerate the air flow passing through the air outlet 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 disposed, and the air outlet 40 may be a long strip with a length direction parallel to the length direction of the housing 10. The upper edge of the outlet 40 is located above and in front of the lower edge of the outlet 40. The upper edge of the air outlet 40 is located on the front surface of the housing 10, so that the front surface of the housing 10 has an air guiding area extending upward from the upper edge of the air outlet 40.

As shown in fig. 2, wind guide 50 has first wind guide surface 501 and second wind guide surface 502. The first air guiding surface 501 is connected with the second air guiding surface 502, the first air guiding surface 501 has a first edge and a second edge, the first edge is located in front of and above the second edge, and the second air guiding surface 502 extends vertically downwards from the second edge of the first air guiding surface 501, forwards and downwards or backwards and downwards. The first edge of the first wind guide surface 501 is located above and in front of the upper edge of the air outlet 40, the first wind guide surface 501 is spaced from the upper edge of the air outlet 40, and the first wind guide surface 501 is spaced from the wind guide area to form an upper air duct. The lower edge of the second wind guiding surface 502 is located right in front of, above, or below the lower edge of the air outlet 40, and the second wind guiding surface 502 and the lower edge of the air outlet 40 are arranged at intervals to form a lower air duct.

The first wind guide surface 501 and the second wind guide surface 502 guide the airflow flowing out from the air outlet 40 into the space between the first wind guide surface 501 and the wind guide area and the space between the second wind guide surface 502 and the lower edge of the air outlet 40.

That is, the lower end of the first air guiding surface 501 is located within the air outlet range of the air outlet 40, and is configured to divide the air flow flowing out of the air outlet 40 into two parts, one part of the air flow flows out from the space between the first air guiding surface 501 and the air guiding area, and the other part of the air flow flows out from the space between the second air guiding surface 502 and the lower edge of the air outlet 40. The first air guiding surface 501 is inclined forward and upward, and the first air guiding surface 501 and the air guiding area can guide the airflow flowing through the gap between the first air guiding surface 501 and the air guiding area forward and upward. The second wind guide surface 502 and the lower edge of the air outlet 40 may guide the airflow flowing through the gap between the second wind guide surface 502 and the lower edge of the air outlet 40 downward, and in this specification, downward may refer to a direction right below, a direction front below, or a direction rear below.

In this embodiment, the air guide 50 is arranged to significantly increase the air outlet angle of the indoor unit of the wall-mounted air conditioner, so that the air flow is blown out from the front upper side and the lower side, the air flow is prevented from directly facing the user, and the comfort level of the user is improved.

Further, the upper edge of the second wind guiding surface 502, that is, the second edge of the first wind guiding surface, is located in front of, directly below, or behind the upper edge of the air outlet 40, and the upper edge of the second wind guiding surface 502 is located in front of and above the lower edge of the air outlet 40. At this time, the upper edge of the second wind guide plate 60 is located in front of the wind outlet 40, and this arrangement can ensure that the lower end of the first wind guide surface 501 is located within the wind outlet range of the wind outlet 40, so as to more conveniently divide the airflow flowing out from the wind outlet 40 into two parts.

In some embodiments of the present invention, the air guide 50 is movably disposed, and when the air guide 50 is in at least two movement positions:

the first edge is located at the front upper part of the second edge, and the second air guiding surface 502 extends vertically downward, forward and downward or rearward and downward from the second edge of the first air guiding surface 501. The first edge of the first air guiding surface 501 is located above and in front of the upper edge of the air outlet 40, the first air guiding surface 501 is spaced from the upper edge of the air outlet 40, and the first air guiding surface 501 is spaced from the air guiding area. The upper edge of second wind guide surface 502 is located below the upper edge of air outlet 40, the upper edge of second wind guide surface 502 is located above the lower edge of air outlet 40, the lower edge of second wind guide surface 502 is located directly in front of, in front of or in front of the lower edge of air outlet 40, or in front of and below, and second wind guide surface 502 and the lower edge of air outlet 40 are arranged at intervals. It should be noted here that the movement position refers to a position that can be moved to, and does not necessarily stop at this position, but may be understood as a position in an area through which the wind is swept. Of course, the dwell may also be at this location.

In these embodiments, the wind guide body 50 is provided movably, and the wind guide body 50 can adjust the size of the interval between the first wind guide surface 501 and the wind guide area and the interval between the second wind guide surface 502 and the lower edge of the outlet 40 while dividing the airflow flowing out from the outlet 40. For example, when the wall-mounted air conditioning indoor unit blows cool air, the air guide 50 moves to significantly increase the distance between the first air guide surface 501 and the air guide area, and significantly decrease the distance between the second air guide surface 502 and the lower edge of the air outlet 40, so that most of the cool air flows to the upper front of the wall-mounted air conditioning indoor unit and is blown out, thereby improving the cooling effect. When the wall-mounted air conditioner indoor unit blows hot air, the air guide body 50 moves to enable the interval between the first air guide surface 501 and the air guide area to be remarkably reduced, and the interval between the second air guide surface 502 and the lower edge of the air outlet 40 to be remarkably increased, so that most hot air flows to the lower portion of the wall-mounted air conditioner indoor unit to be blown out, and the heating effect is better. The position at which the wind guide 50 moves such that the first edge is at the highest position may be the initial position of the wind guide 50.

Further, when the wall-mounted air conditioning room can be set to blow hot air, the air guide body 50 moves to a position where the first edge is located at the highest position, that is, when the first edge is located at the highest position, the first air guide surface 501 contacts the air guide area at least at one position to block the hot air from the air outlet 40 from flowing out from the interval between the first air guide surface 501 and the air guide area, that is, all the hot air flows out downwards from the interval between the second air guide surface 502 and the lower edge of the air outlet 40, and the heating effect is more obvious.

Further, as shown in fig. 4, when the wall-mounted air conditioning room is set to blow hot air, the air guide body 50 moves to a position where the first edge is at the highest position, that is, when the first edge is at the highest position, the first air guide surface 501 is attached to the air guide area. The second edge is located under the upper edge of the air outlet 40 or behind the upper edge, and the second air guide surface can be vertically arranged. In the above arrangement, wind does not enter between the first wind guide surface 501 and the wind guide region, and the wind guide body 50 is more stable.

In some embodiments of the present invention, the first wind guiding surface 501 and the second wind guiding surface 502 are both planar surfaces. Thereby making the airflow passing through the first air guiding surface 501 and the second air guiding surface 502 smoother. Of course, in some other embodiments of the present invention, the first wind guiding surface 501 and the second wind guiding surface 502 may be provided as arc surfaces at the same time or alternatively.

As shown in fig. 5, in some embodiments of the present invention, the included angle B formed by the first air guiding surface 501 and the second air guiding surface 502 is between 120 ° and 180 °, which is more favorable for expanding the air outlet angle of the wall-mounted air conditioner indoor unit. Further, the second edge of first wind-guiding surface 501 is the fillet setting, and first wind-guiding surface 501 is connected with second wind-guiding surface 502 with the fillet promptly for the transition of first wind-guiding surface 501 and second wind-guiding surface 502 is more gentle, and the flow resistance of air current is littleer, and the effect of the reposition of redundant personnel of wind-guiding body 50 wind-guiding is better.

In some embodiments of the present invention, the air guiding region includes a third air guiding surface 101 extending upward from the upper edge of the air outlet 40, and an air duct for blowing air upward is formed between the third air guiding surface 101 and the first air guiding surface 501. The third air guiding surface 101 is a plane, and the air flow flowing through the third air guiding surface 101 flows out smoothly. Of course, in other embodiments of the present invention, the third wind guiding surface 101 may also be a curved surface.

Further, the air guiding area further includes a fourth air guiding surface 102 extending forward or forward and upward from an upper edge of the third air guiding surface 101, and the fourth air guiding surface 102 is configured to guide the air flowing forward and upward to the front or forward and upward. The fourth wind guide surface 102 is a plane or the fourth wind guide surface 102 is a cambered surface.

As shown in fig. 5, in some embodiments of the present invention, the casing has a duct defined therein by upper and lower duct walls spaced apart from each other in the front-to-back direction. The outlet ends of the upper duct wall and the lower duct wall are respectively the upper edge and the lower edge of the air outlet 40 for guiding the air flow in the cabinet to the air outlet 40. An air inlet 70 is formed at the top of the casing, and a cross flow fan 30 having an axis extending in the transverse direction is disposed in the air duct. The three-stage heat exchanger 20 surrounds the crossflow blower 30. 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 through the air inlet 70, exchanges heat with the three-section heat exchanger 20, is finally sucked into the air duct by the cross-flow fan 30, and flows to the air outlet 40.

The upper duct wall includes a volute section 105 and a first outlet section 106 connected to each other. The first air outlet section 106 extends forward and downward from the volute tongue section 105 to the upper edge of the air outlet 40. The first air outlet section 106 is a plane, an included angle a between the first air outlet section 106 and the third air guiding surface 101 is between 80 ° and 100 °, and an included angle between the third air guiding surface 101 and the horizontal plane is between 40 ° and 60 °. Furthermore, the upper edge of the air outlet is arranged in a round angle mode, and air flow is facilitated to be blown upwards and blown out.

The lower air duct wall comprises a volute section 103 and a second air outlet section 104. The volute section 103 is arched rearwardly and its upper end forms the inlet end of the rear duct wall. The second outlet section 104 extends obliquely forward and downward from the scroll section 103 to the lower edge of the outlet 40. The second air outlet section 104 is a plane.

In some embodiments of the present invention, when moving, wind guide 50 causes the first edge to start downward movement or forward downward movement from its highest position, and causes the lower edge of second wind guide surface 502 to start downward movement or rearward downward movement from its highest position.

In some embodiments of the present invention, as shown in fig. 7, the wind guide 50 is rotatably disposed on the housing 10. Further, the air guide body 50 rotates around a transverse axis 107 provided on the housing 10, and the transverse axis 107 is provided at a lower edge of the air outlet 40. The wind guide body 50 can be rotated downward by fixedly connecting the lower edge of the second wind guide surface 502 with the transverse axis 107.

As shown in fig. 6, when the wind guide body 50 rotates downward from the highest position to a preset position, the interval between the first wind guide surface 501 and the wind guide area is gradually expanded, and the ratio of the linear distance L2 between the first wind guide surface 501 and the foremost end of the wind guide area to the linear distance L1 between the first wind guide surface 501 and the upper edge of the wind outlet 40 is between 1.8 and 2.2. When the wall-mounted air conditioner indoor unit blows cold air, the speed of blowing the cold air upwards is low, and when the wall-mounted air conditioner indoor unit is in cold air shower type settlement and contacts with a human body, the speed of the cold air is moderate, and a user feels comfortable.

In some alternative embodiments of the present invention, as shown in fig. 16 and 17, the air guide 50 is vertically slidably disposed on the casing 10, and the air guide 50 is driven to move vertically by the driving device and the transmission device 110. The driving means is a motor and the transmission means 110 is a rack and pinion engaged.

In some embodiments of the present invention, the wall-mounted air conditioner indoor unit further includes an air deflector 60. The air deflector 60 is rotatably disposed between the second air deflecting surface 502 and the lower edge of the air outlet 40, the air deflector 60 can open the gap between the second air deflecting surface 502 and the lower edge of the air outlet 40, and the air deflector 60 can also close the gap between the second air deflecting surface 502 and the lower edge of the air outlet 40 at a specific position. For example, the air guiding plate 60 and the second air outlet section 104 may be located on the same plane, and the second air guiding surface 502 and the lower edge of the air outlet 40 are closed. When the wall-mounted air conditioner indoor unit blows cold air, all the cold air is guided to flow out from the front upper side from the space between the first air guide surface 501 and the air guide area, and the situation that cold air directly blows people is avoided. The air deflector 60 may also be used to separate air flow, and guide the air flow flowing out from the air outlet into the space between the first air guiding surface 501 and the air guiding area and the space between the second air guiding surface 502 and the lower edge of the air outlet. The air guide plate 60 is rotatably provided around the front end thereof, and when hot wind is generated, the air guide plate 60 is rotated to a vertical position, so that all the hot wind is blown downward.

In the initial positions of the air guide body 50 and the air guide plate 60, the air guide plate 60 is disposed between the lower edge of the second air guide surface 502 and the lower edge of the air outlet, and the air guide plate 60 is disposed in an inclined manner with a lower front portion and a higher rear portion, although the air guide plate 60 may also be disposed in an inclined manner.

In some embodiments of the present invention, the baffle 80 is fixedly disposed between the lower edge of the air outlet 40 and the second wind guiding surface 502. For example, in the initial position of the air guide body, the baffle 80 is fixedly disposed between the lower edge of the air outlet 40 and the lower edge of the second air guide surface 502. The rear edge of the baffle 80 is fixedly connected with the lower edge of the air outlet 40. The baffle 80 is provided with micro-holes. The baffle 80 fixed at the lower edge of the air outlet 40 and the second air guide surface 502 is provided with micropores which are vertically arranged, so that air passing through the micropores is blown out vertically and downwards. Of course, in some alternative embodiments, the micro-holes may also be disposed in a direction perpendicular to the surface of the baffle 80. In this embodiment, the air deflector 60 may not be provided, and if the air deflector 60 is provided, the air deflector 60 may be located above the baffle 80.

In some embodiments of the present invention, the baffle 80 may be a horizontally disposed flat plate; or the baffle 80 is a flat plate, the baffle is obliquely arranged, and the baffle and the second air outlet section are positioned on the same plane. Of course, the baffle 80 may have other shapes, for example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 and the second air outlet section 104 are located on the same plane, the lower surface of the baffle 80 is horizontally disposed, and the triangular profile can guide the airflow flowing out from the lower edge of the air outlet 40 to flow forward and downward, so that the baffle 80 has the function of guiding the wind direction.

In some embodiments of the present invention, the lower edge of the air outlet 40 extends downward to form an air guiding wall, the included angle C between the second air guiding surface 502 and the horizontal plane is between 70 ° and 110 °, and the air guiding wall and the second air guiding surface 502 are spaced apart from each other. A lower air duct for downward air flow is formed between the air guide wall and the second air guide surface 502, and the air flow passing through the lower air duct is blown downward. The lower edge of the air outlet is arranged in a round angle mode.

In some embodiments of the present invention, the wind deflector 60 is rotatably disposed in the space between the second wind guiding surface 502 and the lower edge of the wind guiding wall, and the wind deflector 60 has a function of guiding and distributing wind in addition to a function of opening or closing the space between the second wind guiding surface 502 and the wind guiding wall. When one side edge of the air deflector 60 away from the rotation axis 108 is directed to the air outlet 40, the one side edge enters the air outlet 40, so that the air flow from the air outlet 40 is divided into the air flow flowing out from one side surface of the air deflector 60 and the air flow flowing out from the other side surface of the air deflector 60. These two air flows enter the corresponding space between first air guiding surface 501 and the air guiding area and the corresponding space between second air guiding surface 502 and the air guiding wall, respectively, and are blown out. And at the initial positions of the air guide body and the air guide plate, the air guide plate is arranged on the lower edge of the second air guide surface and the lower edge of the air guide wall, and the air guide plate is horizontally arranged.

In some embodiments of the present invention, the wall-mounted air conditioner indoor unit further includes a baffle 80, the baffle 80 is disposed between the lower edge of the air guide wall and the second air guide surface 502, for example, at the initial position of the air guide body, the baffle 80 is fixedly disposed between the lower edge of the air guide wall and the lower edge of the second air guide surface 502. One edge of the baffle 80 is fixedly connected with the lower edge of the air guide wall. The baffle 80 is provided with micropores. Downward airflow is blown out after being scattered by the micropores, and the air outlet is softer. When the baffle 80 realizes downward air outlet, the cost is lower, the fault is not easy to occur, and the appearance is attractive. In this embodiment, the air deflector 60 may not be provided, and if the air deflector 60 is provided, the air deflector 60 may be located above the baffle 80.

Further, the baffle 80 may be a flat plate disposed horizontally. Of course, the baffle 80 may have other shapes, for example, the cross-sectional profile of the baffle 80 is triangular, the upper surface of the baffle 80 and the second air outlet section 104 are located on the same plane, the lower surface of the baffle 80 is horizontally disposed, and the triangular profile can guide the airflow flowing out from the lower edge of the air outlet 40 to flow forward and downward, so that the baffle 80 has the function of guiding the wind direction. The rear end of the lower surface of the baffle 80 is the lower edge of the air guide wall.

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