Referring to fig. 1 to 3, an embodiment of a wall-mounted air conditioner is provided. In one embodiment, the wall-mounted air conditioner includes a housing 100, a heat exchanger 200, and a fresh air module 300; wherein, the shell 100 is provided with an air inlet 101 and an air outlet 102; the heat exchanger 200 is arranged in the shell 100, and an air inlet duct 103 is formed between the heat exchanger 200 and the air inlet 101; the fresh air module 300 is installed in the housing 100 and is located at one end of the heat exchanger 200. The fresh air module 300 comprises a fresh air shell 310 and a fresh air wheel 320 arranged in the fresh air shell 310; wherein, the axial direction of the fresh air wind wheel 320 is arranged in the same direction with the front and back direction of the shell 100; the fresh air casing 310 is formed with a fresh air outlet duct 304 on the air outlet side of the fresh air wind wheel 320, and the fresh air outlet duct 304 extends along the tangential direction of the fresh air wind wheel 320 and faces the air inlet duct 103.

Specifically, the wall-mounted air conditioner is generally provided with an inlet 101 at the top of a housing 100 thereof and an outlet 102 at the bottom thereof. The wall-mounted air conditioner further includes a cross flow wind wheel 500, and a rotation axis of the cross flow wind wheel 500 extends along a length direction of the casing 100; the heat exchanger 200 is arranged between the cross flow wind wheel 500 and the air inlet 101, and surrounds the cross flow wind wheel 500 in a semi-surrounding manner. When the wall-mounted air conditioner works, indoor air is driven by the cross-flow wind wheel 500 to enter the air inlet duct 103 through the air inlet 101, then enters the heat exchanger 200 from the air inlet side of the heat exchanger 200, exchanges heat through the heat exchanger 200, flows to the cross-flow wind wheel 500 from the air outlet side of the heat exchanger 200, and finally is continuously driven by the cross-flow wind wheel 500 to be blown out from the air outlet 102.

The wall-mounted air conditioner is generally applied to a wall surface installed indoors. With the wall-hanging air conditioner use the time towards user's one side be preceding, the one side towards the wall is the back, thereby the wall-hanging air conditioner has along fore-and-aft direction's thickness, along the length of left and right directions to and along the height of up-and-down direction. The fresh air module 300 is installed at one end of the shell 100 of the wall-mounted air conditioner, and the axial direction of the fresh air wind wheel 320 in the fresh air module 300 is arranged in the same direction with the front and back direction of the shell 100, namely, the thickness direction of the fresh air wind wheel 320 is vertical or close to vertical to the length direction of the shell 100. The expression "close to perpendicular" means that the angle at which the two directions intersect is a right-like angle (e.g., 90 DEG + -A, 0 DEG < A.ltoreq.10 DEG, etc.).

For the fresh air module 300, an air inlet cavity 301 communicated with the outdoor environment and an air outlet cavity 302 communicated with the air inlet cavity 301 and used for installing a fresh air wind wheel 320 are arranged in a fresh air shell 310 of the fresh air module 300; the fresh air wheel 320 is installed in the air outlet cavity 302. Wherein, the fresh air casing 310 is further provided with a fresh air outlet duct 304 positioned at the air outlet side of the fresh air wind wheel 320 at one side of the air outlet cavity 302. Because the axial direction of the fresh air wind wheel 320 is arranged in the same direction as the front-back direction of the shell 100, that is, the axial direction of the fresh air wind wheel 320 is perpendicular to the length direction of the shell 100; the fresh air outlet duct 304 extends along the tangential direction of the fresh air wind wheel 320, so that the fresh air outlet duct 304 extends along the length direction of the casing 100, and the outlet of the fresh air outlet duct 304 can directly face the air inlet duct 103. Wherein, the tangential direction is perpendicular to the axial direction of the fresh air wind wheel 320. Thus, the fresh air blown out from the fresh air outlet duct 304 can be directly blown to the air inlet duct 103 according to the original air outlet direction, so as to convey the fresh air to the air inlet side of the heat exchanger 200.

Referring to fig. 3 to 4, when the fresh air module 300 works, the fresh air wheel 320 drives the fresh air pipe 350 to suck outdoor fresh air into the air inlet cavity 301, then the fresh air is sucked by the fresh air wheel 320 in the air outlet cavity 302 along the axial direction thereof and then thrown out along the radial direction thereof, the thrown fresh air is expanded in the fresh air outlet duct 304 and then blown out along the fresh air outlet duct 304, the blown fresh air directly faces the air inlet duct 103 of the wall-mounted air conditioner, and thus the blown fresh air can directly flow to the air inlet duct 103 without changing the direction of the fresh air. The fresh air entering the air inlet duct 103 is further driven by the cross flow wind wheel 500 to pass through the heat exchanger 200 from the air inlet side of the heat exchanger 200, and is further heated by the heat exchanger 200.

It should be noted that the fresh air module 300 may be installed in the left end portion of the casing 100 of the wall-mounted air conditioner, or may be installed in the right end portion of the casing 100. If the fresh air module 300 is installed in the left end of the casing 100, the fresh air duct 304 of the fresh air module 300 may extend rightward and open toward the air inlet duct 103. If the fresh air module 300 is installed in the right end portion of the casing 100, the fresh air duct 304 of the fresh air module 300 may extend leftward and open toward the air inlet duct 103.

According to the technical scheme, the fresh air outlet duct 304 of the fresh air module 300 extends along the tangential direction of the fresh air wind wheel 320, so that the fresh air outlet duct 304 of the fresh air module 300 can extend along the length direction of the shell 100 and directly open towards the air inlet duct 103 by arranging the fresh air wind wheel 320 of the fresh air module 300 in the same axial direction as the front and back direction of the shell 100, and further the fresh air outlet duct 304 can directly convey fresh air to the air inlet duct 103. When the fresh air module 300 works, fresh air blown out from the fresh air outlet duct 304 of the fresh air module 300 can be directly blown to the air inlet duct 103 without changing the wind direction; the fresh air entering the air intake duct 103 is further driven by the cross flow wind wheel 500 to pass through the heat exchanger 200 from the air intake side of the heat exchanger 200, and is finally heated by the heat exchanger 200.

Therefore, the wall-mounted air conditioner can directly guide fresh air to the air inlet side of the heat exchanger 200 by adjusting the installation direction of the fresh air module 300, so that a reversing air duct does not need to be added at the outlet of the fresh air outlet duct 304 of the fresh air module 300. In addition, since the fresh air is directly blown to the air inlet side of the heat exchanger 200 through the fresh air outlet duct 304, the direction of the fresh air is not changed, thereby avoiding the occurrence of large air volume loss due to the change of the direction of the fresh air, and enabling the fresh air module 300 to obtain large fresh air volume.

Referring to fig. 9 to 11, regarding the basic structure of the fresh air module 300, in an embodiment, the fresh air module 300 is disposed in a flat shape; the thickness direction of the fresh air module 300 is arranged in the same direction as the axial direction of the fresh air wind wheel 320. Specifically, the fresh air module 300 includes a fresh air casing 310 disposed in a flat shape, and a fresh air wheel 320 disposed in the fresh air casing 310. Wherein, the fresh air wheel 320 can be a centrifugal wind wheel; the axial direction of the fresh air wind wheel 320 is arranged in the same direction as the thickness direction of the fresh air shell 310; the fresh air outlet duct 304 is formed in the fresh air casing 310 and is perpendicular to the axial direction of the fresh air wind wheel 320, so that the fresh air outlet duct 304 can directly extend towards the air inlet duct 103 along the length direction of the casing 100, and further, the air flow of the fresh air wind wheel 320 can be directly blown to the air inlet duct 103 to be supplied to the air inlet side of the heat exchanger 200.

Specifically, the air outlet characteristic of the fresh air wind wheel 320 is that the wind is sucked in along the axial direction, then is rotated and extruded and then is thrown out along the radial direction, the wind thrown out by the fresh air wind wheel 320 enters the fresh air outlet duct 304 along the tangential direction of the fresh air wind wheel 320 for diffusion, and is blown out along the extending direction of the fresh air outlet duct 304 after the fresh air outlet duct 304 is pressurized. Therefore, when the axial direction of the fresh air wind wheel 320 of the fresh air module 300 is set to be perpendicular to the length direction of the casing 100, the fresh air outlet duct 304 extending along the tangential direction of the fresh air wind wheel 320 can extend towards the left and right direction (i.e. the length direction of the casing 100), and further can face the air inlet duct 103 positioned at the left side or the right side of the fresh air module 300, so that the fresh air blown out from the fresh air outlet duct 304 can directly enter the air inlet duct 103, and a reversing duct does not need to be arranged at the tail end of the fresh air outlet duct 304.

Referring to fig. 11 to 13, optionally, the fresh air casing 310 of the fresh air module 300 includes a volute 311, a casing cover 312 covering the volute 311, and a middle partition 313 installed in the volute 311. An air inlet cavity 301 is formed between the middle partition plate 313 and the shell cover 312 in an enclosing manner, and the air inlet cavity 301 is communicated with the outdoor environment through a fresh air pipe 350; an air outlet cavity 302 is enclosed between the middle partition 313 and the volute 311, and the middle partition 313 is provided with a vent for communicating the air inlet cavity 301 with the air outlet cavity 302. As shown in fig. 14 and 15, the fresh air rotor 320 is installed in the air outlet cavity 302; the fresh air outlet duct 104 is formed at one side of the air outlet cavity 302, and the fresh air outlet duct 104 is located above the fresh air wind wheel 320 and faces the air inlet duct 103 of the wall-mounted air conditioner along the tangential direction of the fresh air wind wheel 320, which is perpendicular to the axial direction of the fresh air wind wheel.

Referring to fig. 3, 9 and 15, further, a fresh air outlet 303 located at the end of the fresh air outlet duct 304 is disposed on a side surface of the fresh air casing 310 facing the heat exchanger 200, and the fresh air outlet 303 protrudes from the side surface of the fresh air casing 310 toward the air inlet duct 103. Therefore, the fresh air outlet 303 is close to or even extends into the air inlet duct 103 to prolong the air supply distance of fresh air, so that the fresh air can be accurately sent into the air inlet duct 103 of the wall-mounted air conditioner. Certainly, in other embodiments, in order to prolong the air supply distance of the fresh air outlet 303, the fresh air outlet 303 can be prolonged or the fresh air outlet pipe is connected to the fresh air outlet 303, and the extending direction of the fresh air outlet pipe is consistent with the extending direction of the fresh air outlet duct 304 of the fresh air module 300, so that in the process of outputting fresh air by the fresh air module 300, the change of the fresh air direction cannot happen, and the loss of the wind wheel is reduced.

Referring to fig. 6 and 9, a fresh air inlet is further disposed at the bottom of the fresh air shell 310, and the fresh air inlet is connected to a fresh air pipe 350 for communicating with the outdoor environment. In order to facilitate the extension of the fresh air duct 350 to the outdoor, the chassis 110 is optionally further provided with a clearance groove 113 on the bottom wall thereof for the passage of the fresh air duct 350. After the new trend module 300 was installed in casing 100, the one end of new trend pipe 350 and the new trend entry linkage of new trend module 300, the other end of new trend pipe 350 is through keeping away empty groove 113 and outwards stretching out to it is outdoor to pass the wall body and stretch out, thereby communicates with outdoor environment, and then new trend module 300 can be with outdoor new trend through new trend pipe 350 suction wherein.

Referring to fig. 5 and 6, in an embodiment, the housing 100 includes a bottom chassis 110 and a face frame 120 mounted on the bottom chassis 110; the fresh air module 300 is disposed in a flat shape, and the front side of the fresh air module 300 is disposed opposite to the front side of the face frame 120. Specifically, the overall appearance of the fresh air module 300 is flat; the front side or the rear side of the fresh air module 300 is perpendicular to the front-rear direction of the casing 100, that is, the thickness direction of the fresh air module 300 is arranged in the same direction as the front-rear direction of the casing 100, so that the front side of the fresh air module 300 is arranged opposite to the front side of the face frame 120.

Referring to fig. 6 to 9, there are various ways for the fresh air module 300 to be fixedly connected to the chassis 110. For example, the bottom of the fresh air module 300 is provided with a positioning portion 307, and the top or the side of the fresh air module 300 is provided with a fixing portion 308; the bottom wall of the chassis 110 is provided with a positioning matching part 111 correspondingly connected with the positioning part 307, and the rear side wall of the chassis 110 is provided with a fixing matching part 112 correspondingly connected with the fixing part 308. One of the positioning portion 307 and the positioning matching portion 111 matching therewith may be a positioning column or a positioning buckle, and the other one is a positioning hole or a positioning slot for inserting the positioning column or the positioning buckle. One of the fixing portions 308 and the fixing engagement portions 112 engaged therewith may be a fixing buckle or a fixing lug with a screw hole, and the other one is a buckle slot for fixing the fixing buckle or a screw post for the fixing lug to pass through by a screw.

When the fresh air module 300 is installed on the chassis 110, the bottom of the fresh air module 300 may be connected to the positioning matching portion 111 of the chassis 110 through the positioning portion 307, so as to position the fresh air module 300 on the chassis 110; then, the fixing portion 308 at the top of the fresh air module 300 is connected and fixed with the fixing matching portion 112 of the chassis 110, so that the fresh air module 300 is integrally fixed on the chassis 110. It can be understood that the number of the positioning portions 307 and the fixing portions 308 of the fresh air module 300 is not limited, and two or three or more than two may be provided, specifically, the positioning portions and the fixing portions may be reasonably arranged according to the size and the installation stability of the fresh air module 300.

Referring to fig. 3 to 5, in an embodiment, it is considered that the fresh air module 300 is disposed in a flat shape, and a thickness direction of the fresh air module 300 is consistent with a front-back direction of the housing 100; since the thickness of the fresh air module 300 is generally smaller than the thickness of the casing 100 in the front-rear direction, a part of the accommodating space is left in the front side of the fresh air module 300 or in the rear side of the fresh air module 300.

In view of this, other internal components (such as the electrical control box 400 and the WiFi module) of the wall-mounted air conditioner may be optionally installed in the accommodating space, so as to reduce the space in the length direction of the wall-mounted air conditioner occupied by the other internal components. Therefore, the length of at least one part of the wall-mounted air conditioner extended by the installation mode of the fresh air module 300 can be offset, so that the wall-mounted air conditioner part is ensured to be kept at the original length of the air conditioner body, or the increased length of the air conditioner body is smaller, and the difference between the length of the air conditioner body of the wall-mounted air conditioner and the original length of the air conditioner body is smaller. Therefore, the problem that the length of the body of the wall-mounted air conditioner is too long can be avoided, and the cost of the wall-mounted air conditioner is reduced.

Referring to fig. 3 to 5, in an embodiment, the electrical control box and the fresh air module 300 of the conventional wall-mounted air conditioner are generally disposed at two ends of the wall-mounted air conditioner, so that the electrical control box occupies a portion of the longitudinal space of the wall-mounted air conditioner. In view of this, in order to avoid the body length of the wall-mounted air conditioner being too long, optionally, the wall-mounted air conditioner includes an electronic control box 400, and the electronic control box 400 and the fresh air module 300 are disposed at the same end of the casing 100; the electric control box 400 is located at the front side or the rear side of the fresh air module 300 so as to be arranged with the fresh air module 300 in the front-rear direction.
