An accommodating chamber 11 is provided, and the housing 10 has two vertical mounting plates 111 for hanging on the wall, a front cover 112 connected to the two mounting plates 111 and a rear wall opposite to the front cover 112 113; the rear wall plate 113 is provided with a first air inlet 1131, and the middle part of the front cover 112 is provided with an air outlet 1121; the air duct assembly 40 is arranged in the accommodation chamber 11 to form an air duct; the air duct corresponds to the first air inlet 1131 and the air outlet 1121, the indoor heat exchanger 30 and the cross-flow fan wheel assembly 20 are arranged in the air duct.

Specifically, the housing 10 of the wall-mounted air conditioner indoor unit in the embodiment of the present invention is arranged in a columnar shape extending up and down to form a columnar accommodating cavity 11 , which makes better use of the corner space in the vertical direction. The casing 10 has two vertical mounting plates 111, and the two mounting plates 111 are respectively fixed on two mutually perpendicular walls on the corner, so that the wall-mounted air conditioner indoor unit can be installed close to the corner. The vertical wall-mounted air conditioner indoor unit is embedded in the corner of the wall through the above method, and is installed vertically along the direction of the corner line. After installation, the vertical wall-mounted air conditioner indoor unit can cover the corner line of its vertical height, making the whole more beautiful. At the same time, a front cover 112 connected thereto is provided between the two mounting plates 111, and the front cover 112 has an exposed surface connected to the two mounting plates 111, wherein the front cover can be composed of one or more plates constitute. The front cover plate is separated from the accommodating cavity by a rear wall plate, which can be fixedly connected with the two mounting plates, or can be integrally formed to facilitate manufacture. The first air inlet is arranged on the rear wall, and the first air inlet is arranged in the shape of one or more grids along the vertical direction of the rear wall, so that the vertical wall-mounted air conditioner indoor unit can enter the air through the back, The air inlet path is increased; at the same time, the air outlet set in the middle of the front cover is separated from the first air inlet by the accommodation cavity, which prevents the air discharged from the air outlet from returning directly through the first air inlet and increases the circulation efficiency. In addition, the rear wall of the rear wall plate and the two walls enclose a vertical open cavity, and the open cavity communicates with the atmosphere through the upper and lower openings. The accommodating cavity communicates with the open cavity through the first air inlet, so that the accommodating cavity communicates with the atmosphere, the air enters the open cavity through the upper and lower openings, and enters the accommodating cavity through the first air inlet to form a The outer air intake section uses the space in the corner to form two vertical air intakes, the upper and lower, forming a new cross-flow air intake method, which enriches the air intake path when the vertical wall-mounted air conditioner indoor unit is installed in the corner.

It should be clarified that the air duct assembly 40 is arranged in the space in the existing accommodation chamber 11 to guide the air to flow in an orderly manner in the accommodation chamber 11 and form a part of the air duct, and the cross-flow wind wheel assembly 20 is installed in the air duct. To drive air flow, the cross-flow wind wheel assembly 20 divides the air duct into an air inlet section inside the machine and an air outlet section inside the machine. The air inlet section inside the machine is connected to the aforementioned air inlet section outside the machine through the first air inlet 1131 to form a new air inlet section. air duct. When the air flows through the machine, it exchanges heat with the indoor heat exchanger 30 arranged in the air duct. The heat transfer path of the heat exchange here is bidirectional. When the temperature of the air is higher than the surface temperature of the indoor heat exchanger 30, Heat is conducted from the air to the indoor heat exchanger 30 . Accordingly, when the temperature of the air is lower than the surface temperature of the indoor heat exchanger 30, the heat transfer path is reversed. By setting the preset temperature value of the indoor unit of the vertical wall-mounted air conditioner, the surface temperature of the indoor heat exchanger 30 is set, and the temperature of the air flowing through the air duct is controlled when it is discharged, thereby adjusting the temperature of the air in the room.

The position of the indoor heat exchanger 30 has a great influence on the heat exchange efficiency. Referring to FIG. 2 , in one embodiment, the indoor heat exchanger 30 is arranged between the first air inlet 1131 and the cross-flow fan assembly 20 , wherein, the air inlet section inside the machine is between the first air inlet 1131 and the cross-flow wind wheel assembly 20, the air pressure in the air inlet section inside the machine is negative pressure, and the air outlet 1121 and the cross-flow wind wheel assembly 20 is the air outlet section inside the machine. Air section, the air pressure in the air outlet section inside the machine is positive pressure. The air in the air inlet section of the machine is sucked into the cross-flow wind wheel assembly 20 by negative pressure. Compared with the air in the air outlet section of the machine being discharged by positive pressure through the cross-flow wind wheel assembly 20, the flow process of the air sucked by negative pressure Smoother, more even flow with less turbulence. Placing the indoor heat exchanger 30 in the air inlet section of the machine is conducive to full contact between the air and the indoor heat exchanger 30, uniform heat exchange, and improved heat exchange efficiency.

In order to further enrich the air intake path when the vertical wall-mounted air conditioner is installed in a corner, as shown in FIG. , by adding a second air inlet 1122 on the front cover 112 to allow air to enter the accommodating chamber 11 in the horizontal direction, a horizontal air inlet path is added to further improve the way of cross-flow air inlet, thereby increasing the The intake air volume of the accommodating cavity 11. Certainly, the second air inlet 1122 can be arranged on the mounting plate 111 close to any side, so that the air can enter along the horizontal direction close to the wall, further optimizing the air intake path.

Enlarging the cross-sectional area of the indoor heat exchanger 30 helps to promote heat exchange between the air and the indoor heat exchanger 30, thereby improving heat exchange efficiency. Referring to FIG. 1 , in one embodiment, the indoor heat exchanger 30 is bent and arranged. Compared with a flat plate, the bent arrangement can increase the contact area of the indoor heat exchanger 30 . Certainly, the bent shape may also be an arc surface, and by increasing the contact area, the heat exchange efficiency between the indoor heat exchanger 30 and the air is promoted. The indoor heat exchanger 30 has two convective heat exchange parts 31 and a bent part 32 connecting the two convective heat exchange parts 31 , and the two convective heat exchange parts 31 are respectively disposed at the first air inlet 1131 and the second air inlet 1122 . It should be clarified that the setting mentioned here means that the convective heat exchange part 31 can cover the air inlet, and in addition, there is a corresponding gap between the convective heat exchange part 31 and the air inlet. The advantage is that a heat exchange space fully in contact with the air is formed between the convection heat exchange part 31 and the air inlet, which further improves the heat exchange efficiency.

The second air inlet 1122 and the air outlet 1121 are located on the front cover 112. In order to reduce the air directly flowing back into the machine, as shown in FIG. 3, in another embodiment, the front cover 112 is bent to form a Plates with different angles are formed, including a first plate 112A opposite and parallel to the rear wall 113 and two second plates separated on both sides of the first plate 112A and connected to the two mounting plates 111 respectively 112B, the three boards form an included angle with each other or transition into different angles through the arc panels, the second air inlet 1122 is placed on one of the second boards 112B, and the air outlet 1121 is placed on the first board 112A, As a result, the air inlet and outlet directions form an included angle, which reduces the direct return of the air to the machine without sufficient heat exchange with the indoor air, and improves the circulation efficiency of the air outside the machine.

The bent shape of the front cover 112 is easy to produce edges and corners. When the vertical wall-mounted air conditioner indoor unit is installed on the wall, the exposed surface of the front cover 112 is likely to come into contact with the human body, and it is easy to cause injury when impact occurs. As shown in FIG. 3 , the solid lines with arrows in the figure indicate planes or spaces such as surfaces, cavities, and holes. The first plate body 112A is respectively connected with the two second plate bodies 112B in an arc shape, so that the front cover plate forms a bent shape, and the exposed surface of the front cover plate 112 transitions along a smooth curved surface, eliminating sharp edges and corners with sudden changes in curvature, and improving contact safety sex.

It is convenient for users to control the air outlet. Referring to Figure 4, in one embodiment, the indoor unit of the vertical wall-mounted air conditioner also includes a controller (not shown in the figure). By setting an independent controller or using the original Some controllers control the cross-flow wind wheel assembly 20 to work. The cross-flow rotor assembly 20 includes a vertically extending cross-flow rotor 21 and a drive motor 22 connected in transmission with the cross-flow rotor 21 ; the controller is electrically connected to the drive motor 22 to control the cross-flow rotor assembly 20 to work. The working status here includes rotation, stop and rotation speed, so that users can better control the air supply of the indoor unit of the vertical wall-mounted air conditioner.

To improve air flow, increase the flow rate. Referring to FIG. 2, in one embodiment, the air duct assembly 40 includes a volute part 41 and a volute tongue 42. As is well known, the volute part 41 follows a certain curved surface design, and the purpose is to guide air to flow through the curved surface of the volute part 41. , to reduce the turbulent flow in the air duct and increase the flow velocity. The curved surface may be a curved surface conforming to a design such as a constant velocity spiral, an equiangular spiral, or other curves, and a corresponding cross-sectional curve is selected according to actual needs to guide the air to pass through. The volute tongue 42 is generally arranged at the air outlet section close to the wind wheel assembly 20, and its main function is to reduce the impact generated by the air flowing and reduce wind noise. The volute part 41 extends from the side of the air outlet away from the second air inlet 1122 to the accommodating cavity 11, maximizing the length of the volute part 41 in a limited space, and better exerting the drainage effect of the volute part 41 . The volute tongue 42 extends from the side of the air outlet 1122 close to the second air inlet 1122 to the accommodating chamber 11 to better play the noise reduction function of the volute tongue 42, and the air duct is formed between the volute case part 41 and the volute tongue 42 The air outlet section increases the flow rate of the air circulation, thereby improving the circulation efficiency.

In order to better control the air supply direction and prevent turbulent flow at the air outlet 1121 due to unbalanced air volume, in an embodiment. As shown in Figure 5, in one embodiment, the indoor unit of the vertical wall-mounted air conditioner is provided with an air deflector group 50 at the position corresponding to the air outlet 1121, and the air deflector group 50 is arranged by a plurality of pieces horizontally. The wind guide vane 51 is formed, and the wind guide vane 51 can rotate up and down relative to the air outlet 1121, so that the vertical wall-mounted air conditioner indoor unit can supply air in the up and down direction. Of course, there are many ways to connect the rotation. For example, the wind guide vane 51 can be rotatably mounted on the bracket by setting a bracket, or the wind guide vane 51 can be directly rotated and installed on the front cover 112 where the air outlet 1121 is located. , those skilled in the art can obtain the corresponding technical solutions through the embodiments of the present invention and the accompanying drawings, which will not be repeated here.
