Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a wall-mounted air conditioner. Background Technology

[0002] In related technologies, wall-mounted air conditioners are equipped with fresh air devices. These devices can purify outdoor air and introduce it into the room, thereby replenishing the room with fresh air. The fresh air outlet of the fresh air device is equipped with an air outlet grille, through which fresh air is blown outward. Dust or debris can easily fall into the fresh air outlet, resulting in a poor user experience. Utility Model Content

[0003] This application aims to at least partially address one of the aforementioned technical problems in the prior art. To this end, this application proposes a wall-mounted air conditioner with an air outlet valve that protects the fresh air outlet and improves the user experience.

[0004] The wall-mounted air conditioner according to an embodiment of this application includes a casing, an accommodating cavity formed inside the casing, and an air outlet on the casing. The casing serves a protective function and constitutes the overall external structure of the wall-mounted air conditioner.

[0005] The wall-mounted air conditioner also includes a fresh air housing, which is disposed within the accommodating cavity. A fresh air duct is formed within the fresh air housing, and the housing has a fresh air inlet and a fresh air outlet, both of which are connected to the fresh air duct. Outdoor air can enter the fresh air duct through the fresh air inlet, and the outdoor air within the duct can enter the room through the fresh air outlet and the housing outlet. The housing outlet provides space for the fresh air to exit.

[0006] The wall-mounted air conditioner also includes a fresh air fan, which is installed inside the fresh air housing. The rotation of the fresh air fan allows outdoor air to enter the fresh air housing from the fresh air inlet, and allows the outdoor air entering the fresh air housing to enter the room through the fresh air outlet and the housing outlet.

[0007] The wall-mounted air conditioner also includes an air outlet valve, which is used to open or close the fresh air outlet. When the air outlet valve is open, outdoor air in the fresh air duct can enter the room through the fresh air outlet; when the air outlet valve is closed, outdoor air in the fresh air duct cannot enter the room through the fresh air outlet.

[0008] The wall-mounted air conditioner also includes a drive device, which is connected to the air outlet valve. The drive device is used to drive the air outlet valve to move, so that the air outlet valve opens or closes the fresh air outlet. The air outlet valve is connected to the drive device through a fastening structure.

[0009] The wall-mounted air conditioner also includes a cover plate, which is detachably installed on the air outlet valve and is used to cover the fastening structure.

[0010] According to the wall-mounted air conditioner of the present application embodiment, the air outlet valve can protect the fresh air outlet when closing the fresh air outlet, and the cover can cover the fastening structure to avoid the fastening structure being exposed, which is conducive to improving the user experience of the wall-mounted air conditioner.

[0011] According to some embodiments of this application, the driving device includes a driving component and a transmission mechanism. The driving component is tractively connected to the transmission mechanism, and the transmission mechanism is connected to the air outlet valve. The driving component is used to drive the air outlet valve to translate in the air outlet direction of the fresh air outlet via the transmission mechanism. The movement of the air outlet valve is translational, which is simple and easy to implement. Furthermore, the front of a wall-mounted air conditioner is generally an open indoor area, making it less likely for the air outlet valve to collide with other indoor objects during translation.

[0012] According to some embodiments of this application, the transmission mechanism includes a gear, which is connected to the driving member, and the driving member is used to drive the gear to rotate. The gear transmission method has a simple structure and reliable transmission.

[0013] The transmission mechanism further includes a first rack, which meshes with the gear for transmission. The first rack is connected to the air outlet valve via the fastening structure. When the gear rotates, it drives the first rack to translate, and when the first rack translates, it drives the air outlet valve to move synchronously, thereby opening or closing the fresh air outlet valve in a translational manner.

[0014] According to some embodiments of this application, the first rack includes a first rack body and a connecting portion. The gear meshes with the first rack body for transmission, and the connecting portion is connected to the first rack body. The connecting portion is used to connect with an air outlet valve, thereby separating the connection position of the first rack with the air outlet valve from the transmission position with the gear, so that the rotation of the gear will not interfere with the movement of the air outlet valve.

[0015] The air outlet valve includes a valve body and a valve connecting cylinder. The valve body is used to open or close the fresh air outlet. The valve connecting cylinder is located on the side of the valve body facing the drive device and is connected to the valve body. The connecting part is connected to the valve connecting cylinder through the fastening structure. The connecting part is used to connect with the air outlet valve, thereby separating the connection position of the first rack with the air outlet valve and the transmission position with the gear, so that the rotation of the gear will not interfere with the movement of the air outlet valve.

[0016] According to some embodiments of this application, the connecting portion includes a protrusion inserted into the valve connecting cylinder. One of the protrusion and the valve connecting cylinder has a first guide rail, and the other has a first guide groove. The first guide rail and the first guide groove are slidably engaged, and the length direction of the first guide rail is the same as the length direction of the first rack body. The valve connecting cylinder can translate relative to the protrusion along the length direction of the first guide rail. The protrusion provides guidance for the translation of the valve connecting cylinder, making the translation operation of the valve connecting cylinder accurate and reliable.

[0017] According to some embodiments of this application, the valve connecting cylinder is provided with a mounting arm, which is adapted to connect with the inner wall of the valve connecting cylinder. The protrusion is provided with a protrusion mounting hole, and the fastening structure includes a fastening screw, which passes through the mounting arm and is fastened to the protrusion mounting hole. For example, the mounting arm is a plate-like structure with a through hole, through which the fastening screw passes and is fastened to the protrusion mounting hole.

[0018] According to some embodiments of this application, the fastening structure includes: a first snap-fit ​​structure and a second snap-fit ​​structure. The first snap-fit ​​structure is disposed on the connecting portion, and the second snap-fit ​​structure is disposed on the valve connecting cylinder. The second snap-fit ​​structure is adapted to snap-fit ​​and fix with the first snap-fit ​​structure. One of the first snap-fit ​​structure and the second snap-fit ​​structure is a buckle, and the other is a groove. The first snap-fit ​​structure and the second snap-fit ​​structure are snap-fit ​​and fixed, thereby realizing the snap-fit ​​connection between the connecting portion and the valve body.

[0019] When assembling the connecting part and the valve connecting cylinder, the first and second snap-fit ​​structures can be snapped together first, and then the fastening screws can be passed through the through holes on the mounting arm and tightened into the mounting holes of the protrusions. The double fastening method helps to improve the connection between the connecting part and the valve connecting cylinder, thus making it less likely for the first rack to separate from the air outlet valve.

[0020] According to some embodiments of this application, the cover plate is located on the side of the valve body facing away from the driving device. On a plane perpendicular to the air outlet direction, the projection of the valve body on the plane is within the projection range of the cover plate on the plane. In this way, the cover plate can completely obscure the air outlet valve from the front side, so the user can only see the cover plate and not easily see the air outlet valve. The cover plate can also serve as a decorative panel; choosing an aesthetically pleasing cover plate can enhance the user experience of the wall-mounted air conditioner.

[0021] According to some embodiments of this application, the valve body is provided with a third snap-fit ​​structure, and the cover plate is provided with a fourth snap-fit ​​structure. The fourth snap-fit ​​structure is adapted to snap-fit ​​and fix with the third snap-fit ​​structure. One of the third snap-fit ​​structure and the fourth snap-fit ​​structure is a buckle, and the other is a groove. The snap-fit ​​and fixation of the third snap-fit ​​structure and the fourth snap-fit ​​structure realizes the snap-fit ​​connection between the valve body and the cover plate.

[0022] According to some embodiments of this application, both the valve body and the cover plate are corrugated plates. The middle portion of the valve body and the cover plate protrudes forward from their upper and lower sides. The upper and lower sides of the valve body are provided with the third snap-fit ​​structure, and the upper and lower sides of the cover plate are provided with the fourth snap-fit ​​structure. When it is necessary to disassemble the cover plate from the air outlet valve, a pressing force can be applied to the middle position of the cover plate towards the air outlet valve. This pressing force causes the upper and lower sides of the cover plate to lift, thereby separating the third and fourth snap-fit ​​structures. When it is necessary to install and fix the cover plate to the air outlet valve, first, the cover plate is fitted to the air outlet valve, the positions of the third and fourth snap-fit ​​structures are aligned, and a pressing force is applied to the upper and lower sides of the cover plate towards the air outlet valve. This pressing force causes the third and fourth snap-fit ​​structures to snap and fix together, thus achieving a fixed connection between the cover plate and the air outlet valve.

[0023] According to some embodiments of this application, the cover plate is movably connected to the valve connecting cylinder. The fastening screws of the valve connecting cylinder and the connecting part are located in the hollow area of ​​the valve connecting cylinder. After the cover plate is connected to the valve connecting cylinder, the cover plate can cover the hollow area of ​​the valve connecting cylinder, thereby covering the fastening screws.

[0024] According to some embodiments of this application, the cover plate includes a cover plate body and a second guide rail. The second guide rail is connected to the cover plate body, and the length direction of the second guide rail is the same as the length direction of the first rack body. The valve connecting cylinder is provided with a second guide groove, and the second guide rail can move within the second guide groove. The cover plate body is adapted to be interference-fitted with or separate from the valve connecting cylinder. When the cover plate body moves relative to the valve connecting cylinder, the second guide rail moves in the second guide groove, ensuring that the movement direction of the cover plate is the length direction of the second guide rail, and the cover plate is not easily deflected. When the cover plate body is fixed relative to the valve connecting cylinder, the cover plate body and the valve connecting cylinder are interference-fitted.

[0025] According to some embodiments of this application, the fresh air housing includes a first housing and a second housing, the second housing being detachably connected to the first housing, forming an air inlet cavity between the second housing and the first housing, and the fresh air inlet communicating with the air inlet cavity, the fresh air inlet being disposed on the first housing and / or the second housing. The second housing and the first housing are designed as separate units, making it convenient to install and disassemble the components inside the air inlet cavity.

[0026] The fresh air housing also includes a third housing, which is detachably connected to the second housing. An air outlet cavity is formed between the third housing and the second housing, and the air outlet cavity is connected to the air inlet cavity. The fresh air outlet is disposed on the second housing and / or the third housing, and the fresh air outlet is connected to the air outlet cavity. The separate design of the third housing and the second housing facilitates the installation and disassembly of the components inside the air outlet cavity.

[0027] The wall-mounted air conditioner also includes an air guide duct, which is installed at the fresh air outlet. The fresh air outlet and the casing air outlet are connected through the air guide duct. The air guide duct can guide the outdoor air blown out of the fresh air outlet to the casing air outlet, and then blow it into the room through the casing air outlet.

[0028] According to some embodiments of this application, the first housing, the second housing, and the third housing are arranged sequentially along the length of the housing, and the driving component is installed on the first housing and / or the second housing to achieve the installation and fixation of the driving component.

[0029] According to some embodiments of this application, the housing includes a sealing plate and a mounting plate. The sealing plate has an annular structure, and the mounting plate is connected to the sealing plate. The mounting plate has a mounting hole for the valve connecting cylinder to pass through. The housing air outlet is surrounded by the sealing plate and the mounting plate, and the air outlet end of the air guide tube abuts against the sealing plate and the mounting plate. The sealing plate and the mounting plate are used to seal the gap between the air guide tube and the housing. Therefore, the air guide tube can better and more effectively guide the outdoor air blown from the fresh air outlet to the housing air outlet, preventing the outdoor air blown from the fresh air outlet from leaking into the housing.

[0030] When the air outlet valve abuts against the sealing plate, the fresh air outlet is closed; when the air outlet valve separates from the sealing plate, the fresh air outlet is opened.

[0031] According to some embodiments of this application, the wall-mounted air conditioner further includes a purification component installed within the air inlet cavity. The rotation of the fresh air fan allows outdoor air to enter the fresh air housing from the fresh air inlet, and also allows the outdoor air entering the fresh air housing to pass through the purification component before entering the room from the fresh air outlet. The purification component is used to purify the fresh air blown into the room, improving the cleanliness of the indoor air.

[0032] According to some embodiments of this application, the wall-mounted air conditioner further includes an indoor heat exchanger disposed within the accommodating cavity. The first housing is disposed on the side of the second housing away from the indoor heat exchanger, and the third housing is disposed on the side of the second housing closer to the indoor heat exchanger. The first housing, second housing, and third housing are arranged in a reasonable manner, which can make full use of the space in the left-right direction of the wall-mounted air conditioner.

[0033] According to some embodiments of this application, the wall-mounted air conditioner further includes an air inlet valve for opening or closing the fresh air inlet. The gear is a double gear and includes a first gear section and a second gear section. The number of teeth in the first gear section is less than the number of teeth in the second gear section. The first rack meshes with the first gear section. The transmission mechanism further includes a second rack that meshes with the second gear section for transmission. The second rack is disposed on the air inlet valve. When the second gear section rotates to drive the second rack to move, the second rack drives the air inlet valve to move, so that the air inlet valve opens or closes the fresh air inlet.

[0034] According to some embodiments of this application, the air outlet of the housing is located at the bottom of the housing to guide the outdoor air blown out from the fresh air outlet to flow forward and downward into the room. This allows the fresh air to flow forward and downward, ensuring that the fresh air reaches the ground and travels a sufficient distance. It also visualizes the fresh air function, providing users with a direct visual experience of the fresh air supply.

[0035] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0063] Some embodiments of this application provide a wall-mounted air conditioner 10.

[0064] Typically, air conditioners are split-type air conditioners, which include an indoor unit and an outdoor unit. The indoor and outdoor units are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and a heat exchange fan.

[0065] The outdoor unit includes a compressor, an outdoor heat exchanger, an outdoor fan, and a throttling device. The compressor, outdoor heat exchanger, throttling device, and indoor heat exchanger are connected in sequence to form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger and the indoor heat exchanger, respectively, to achieve the air conditioner's cooling mode or heating mode.

[0066] The compressor is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0067] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of the air conditioner, the outdoor heat exchanger operates as a condenser, causing the refrigerant compressed by the compressor to dissipate heat to the outdoor air and condense. In the heating mode of the air conditioner, the outdoor heat exchanger operates as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0068] In some embodiments, the outdoor heat exchanger may include heat exchange fins to increase the contact area between outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0069] The outdoor fan is configured to draw in outside air into the outdoor unit and expel the outdoor air, which has been heated by the outdoor heat exchanger, to the outside. The outdoor fan provides power for the flow of outdoor air.

[0070] A throttling device connects the outdoor and indoor heat exchangers. It regulates the refrigerant pressure flowing through both devices, thereby controlling the refrigerant flow rate between them. The flow rate and pressure of the refrigerant between the outdoor and indoor heat exchangers affect their heat exchange performance. The throttling device can be a throttling tube, an electronic valve, etc. When the throttling device is an electronic valve, its opening is adjustable to regulate the refrigerant flow rate and pressure.

[0071] In some designs, the air conditioner may include a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner can perform a cooling mode or a heating mode.

[0072] An indoor heat exchanger is configured to exchange heat between indoor air and a refrigerant transported within the indoor heat exchanger. In some embodiments, the indoor heat exchanger may include heat exchange fins to increase the contact area between the indoor air and the refrigerant transported within the indoor heat exchanger, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0073] The heat exchange fan is configured to draw indoor air into the indoor unit and deliver the indoor air, after heat exchange with the indoor heat exchanger, into the room, providing power for the flow of indoor air.

[0074] The following is combined Figures 1-17 A detailed description of the wall-mounted air conditioner 10 according to an embodiment of this application.

[0075] The wall-mounted air conditioner 10 of this application is an indoor unit. The wall-mounted air conditioner 10 is typically installed on a wall, for example, in the upper area of ​​an interior wall.

[0076] Reference Figures 1-4 As shown, the wall-mounted air conditioner 10 according to an embodiment of this application includes a housing 1, with an accommodating cavity formed inside the housing 1, and a housing air outlet 11 provided on the housing 1. The housing 1 can play a protective role and constitute the overall external structure of the wall-mounted air conditioner 10.

[0077] Typically, the casing 1 is a long, rectangular shell, with its length running horizontally along the wall. Figures 1-3 The left and right directions are indicated in the diagram. In actual products, in order to drain condensate, in some embodiments the casing 1 is mounted horizontally on the wall, forming a small angle with the horizontal plane.

[0078] Reference Figures 5-7 As shown, the wall-mounted air conditioner 10 also includes a fresh air housing 2, which is disposed within the accommodating cavity. A fresh air duct is formed within the fresh air housing 2. The fresh air housing 2 is provided with a fresh air inlet 24 and a fresh air outlet 25, both of which are connected to the fresh air duct. Outdoor air can enter the fresh air duct through the fresh air inlet 24, and the outdoor air in the fresh air duct can enter the room through the fresh air outlet 25 and the housing outlet 11. The housing outlet 11 provides space for the fresh air outlet 25 to discharge air.

[0079] The wall-mounted air conditioner 10 also includes a fresh air fan (not shown in the figure). The fresh air fan is installed inside the fresh air housing 2. When the fresh air fan rotates, outdoor air can enter the fresh air housing 2 from the fresh air inlet 24, and outdoor air entering the fresh air housing 2 can enter the room through the fresh air outlet 25 and the housing outlet 11.

[0080] In some embodiments, the wall-mounted air conditioner 10 further includes a first motor (not shown in the figure), which is disposed inside the fresh air housing 2 and connected to the fresh air fan. The first motor is used to drive the fresh air fan to rotate. The first motor can be an external rotor motor or an internal rotor motor.

[0081] In some embodiments, the axes of the first motor and the fresh air fan are both along the length of the housing 1.

[0082] Reference Figure 3 , Figures 6-7 As shown, the wall-mounted air conditioner 10 also includes an air outlet valve 41, which is used to open or close the fresh air outlet 25. When the air outlet valve 41 opens the fresh air outlet 25, outdoor air in the fresh air duct can enter the room through the fresh air outlet 25; when the air outlet valve 41 closes the fresh air outlet 25, outdoor air in the fresh air duct cannot enter the room through the fresh air outlet 25.

[0083] Reference Figure 5 , Figures 7-10As shown, the wall-mounted air conditioner 10 also includes a drive device 5, which is connected to the air outlet valve 41. The drive device 5 drives the air outlet valve 41 to move, thereby opening or closing the fresh air outlet 25. The air outlet valve 41 and the drive device 5 are connected by a fastening structure. The air outlet valve 41 is subjected to force during movement. Using a fastening structure to connect the air outlet valve 41 to the drive device 5 ensures smooth and reliable movement of the air outlet valve 41 and effectively prevents the air outlet valve 41 from detaching from the drive device 5.

[0084] Reference Figure 1 , Figure 3 , Figures 5-10 , Figures 15-17 As shown, the wall-mounted air conditioner 10 also includes a cover plate 43, which is detachably installed on the air outlet valve 41. The cover plate 43 is used to cover the fastening structure. Specifically, when the cover plate 43 is installed on the air outlet valve 41, the cover plate 43 covers the fastening structure, preventing the fastening structure from being exposed, thus making the wall-mounted air conditioner 10 aesthetically pleasing. When the cover plate 43 is removed from the air outlet valve 41, the fastening structure is exposed, making it convenient for users to install and remove the fastening structure.

[0085] In other words, when operation of the fastening structure is required, the cover plate 43 is removed from the air outlet valve 41, and when operation of the fastening structure is not required, the cover plate 43 is installed on the air outlet valve 41. The cover plate 43 is not subjected to force during the movement of the air outlet valve 41 or when the air outlet valve 41 is stopped.

[0086] According to the wall-mounted air conditioner 10 of this application embodiment, the air outlet valve 41 can protect the fresh air outlet 25 when closing the fresh air outlet 25, and the cover plate 43 can cover the fastening structure to avoid the fastening structure being exposed, which is conducive to improving the user experience of the wall-mounted air conditioner 10.

[0087] In some embodiments of this application, reference is made to Figure 5 , Figures 7-10 As shown, the driving device 5 includes a driving component 51 and a transmission mechanism 52. The driving component 51 is connected to the transmission mechanism 52, and the transmission mechanism 52 is connected to the air outlet valve 41. The driving component 51 is used to drive the air outlet valve 41 to move horizontally in the air outlet direction of the fresh air outlet 25 through the transmission mechanism 52, so that the air outlet valve 41 opens or closes the fresh air outlet 25. The movement of the air outlet valve 41 is horizontal, which is simple and easy to implement. Moreover, the front of the wall-mounted air conditioner 10 is generally an open indoor area, so the air outlet valve 41 is unlikely to collide with other indoor objects when it moves horizontally.

[0088] In some embodiments of this application, the drive component 51 is an electric drive component. The electric drive component drives the transmission mechanism 52 to move, and when the transmission mechanism 52 moves, it drives the air outlet valve 41 to move, so that the adjustment process of the air outlet valve 41 is electric, and the user does not need to manually adjust the air outlet valve 41, and the opening degree of the air outlet valve 41 is accurate.

[0089] In a specific embodiment, the driving component 51 can be a stepper motor. The output shaft of the stepper motor drives the transmission mechanism 52 to move. When the transmission mechanism 52 moves, it drives the air outlet valve 41 to move, thereby changing the relative position of the air outlet valve 41 and the fresh air outlet 25, so that the air outlet valve 41 opens or closes the fresh air outlet 25.

[0090] In some embodiments, the drive 51 may be a stepper motor or a combination of a stepper motor and a reducer.

[0091] In some embodiments of this application, reference is made to Figures 7-10 As shown, the transmission mechanism 52 includes a gear 521, which is connected to the driving member 51. The driving member 51 drives the gear 521 to rotate. The gear 521 transmission method has a simple structure and reliable transmission.

[0092] For example, in Figures 7-8 In the example, the drive unit 51 has an output shaft, and the gear 521 can be directly mounted on the output shaft of the drive unit 51. When the output shaft rotates, it drives the gear 521 to rotate synchronously.

[0093] For example, in some embodiments not shown in the figure, the transmission mechanism 52 further includes a mounting shaft, which is connected to the output shaft of the drive member 51 via a coupling. The gear 521 is mounted on the mounting shaft. When the output shaft rotates, it drives the mounting shaft to rotate synchronously, and when the mounting shaft rotates, it drives the gear 521 to rotate synchronously.

[0094] In some embodiments of this application, reference is made to Figures 7-10 As shown, the transmission mechanism 52 also includes a first rack 522, which meshes with a gear 521 for transmission. The first rack 522 is connected to the air outlet valve 41 via a fastening structure. When the gear 521 rotates, it drives the first rack 522 to translate. When the first rack 522 translates, it drives the air outlet valve 41 to move synchronously, thereby opening or closing the fresh air outlet 25 of the air outlet valve 41 by translation. The meshing transmission between the first rack 522 and the gear 521 provides reliable movement, a simple structure, and is easy to maintain.

[0095] In some embodiments of this application, reference is made to Figures 7-11As shown, the first rack 522 includes a first rack body portion 5221 and a connecting portion 5222. The gear 521 meshes with the first rack body portion 5221 for transmission, and the connecting portion 5222 is connected to the first rack body portion 5221. The connecting portion 5222 is used to connect with the air outlet valve 41. Thus, the connection position of the first rack 522 with the air outlet valve 41 and the transmission position with the gear 521 are separated, so that the rotation of the gear 521 will not interfere with the movement of the air outlet valve 41.

[0096] Reference Figures 7-12 As shown, the air outlet valve 41 includes a valve body 411 and a valve connecting cylinder 412. The valve body 411 is used to open or close the fresh air outlet 25. The valve connecting cylinder 412 is located on the side of the valve body 411 facing the drive device 5 and is connected to the valve body 411. The connecting part 5222 is connected to the valve connecting cylinder 412 by a fastening structure. When the fastening structure connects the connecting part 5222 and the valve connecting cylinder 412, the deformation of the valve connecting cylinder 412 has little impact on the valve body 411 and does not affect the closing effect of the valve body 411 on the fresh air outlet 25.

[0097] In some embodiments of this application, reference is made to Figures 10-12 As shown, the connecting part 5222 includes a protrusion 52221, which is inserted into the valve connecting cylinder 412. One of the protrusion 52221 and the valve connecting cylinder 412 has a first guide rail 413, and the other has a first guide groove 52222. The first guide rail 413 and the first guide groove 52222 slide against each other. The length direction of the first guide rail 413 is the same as the length direction of the first rack body 5221. The valve connecting cylinder 412 can translate relative to the protrusion 52221 along the length direction of the first guide rail 413. The protrusion 52221 provides guidance for the translation of the valve connecting cylinder 412, making the translation of the valve connecting cylinder 412 accurate and reliable, thus ensuring the accurate and reliable translation of the air outlet valve 41.

[0098] exist Figures 10-12 In the example shown, the valve connecting cylinder 412 has a first guide rail 413 and the protrusion 52221 has a first guide groove 52222.

[0099] In some embodiments not shown in the figure, the first guide groove 52222 may also be provided on the valve connecting cylinder 412, and the first guide rail 413 may be provided on the protrusion 52221.

[0100] In some embodiments of this application, the fastening screw 91 passes through the air outlet valve 41 and is fastened to the connection portion 5222.

[0101] In some embodiments of this application, reference is made to Figures 10-12As shown, the valve connecting cylinder 412 is provided with a mounting arm 414, which is adapted to connect with the inner wall of the valve connecting cylinder 412. The protrusion 52221 is provided with a protrusion mounting hole 52224. The fastening structure includes a fastening screw 91, which passes through the mounting arm 414 and is fastened to the protrusion mounting hole 52224.

[0102] In some embodiments of this application, the mounting arm 414 is a plate-shaped structure, and the mounting arm 414 is provided with a through hole 4141. The fastening screw 91 passes through the through hole 4141 and is fastened to the protrusion mounting hole 52224.

[0103] In some embodiments of this application, reference is made to Figures 9-12 As shown, the fastening structure includes a first snap-fit ​​structure 52223 and a second snap-fit ​​structure 415. The first snap-fit ​​structure 52223 is disposed on the connecting part 5222, and the second snap-fit ​​structure 415 is disposed on the valve connecting sleeve 412. The second snap-fit ​​structure 415 is adapted to snap-fit ​​and fix with the first snap-fit ​​structure 52223. One of the first snap-fit ​​structure 52223 and the second snap-fit ​​structure 415 is a snap-fit, and the other is a snap-fit ​​groove. The snap-fit ​​and fixation of the first snap-fit ​​structure 52223 and the second snap-fit ​​structure 415 realizes the snap-fit ​​connection between the connecting part 5222 and the valve body part 411.

[0104] For example, in Figures 10-12 In the example, the first snap-fit ​​structure 52223 is a snap-fit, and the second snap-fit ​​structure 415 is a slot.

[0105] For example, in some embodiments not shown in the figure, the first snap-fit ​​structure 52223 is a slot and the second snap-fit ​​structure 415 is a buckle.

[0106] In some embodiments of this application, there may be multiple first snap-fit ​​structures 52223, and the number of second snap-fit ​​structures 415 is equal to that of the first snap-fit ​​structures 52223, with their positions corresponding one-to-one. Figures 10-12 In the example, there are two first snap-fit ​​structures 52223. In some embodiments not shown in the figure, the first snap-fit ​​structures 52223 can be three, four, five, etc.

[0107] When assembling the connecting part 5222 and the valve connecting cylinder 412, the first snap-fit ​​structure 52223 and the second snap-fit ​​structure 415 can be snapped and fixed first, and then the fastening screw 91 can be passed through the through hole 4141 on the mounting arm 414 and fastened to the protrusion mounting hole 52224. The double fastening method helps to improve the connection between the connecting part 5222 and the valve connecting cylinder 412, thereby making it difficult for the first rack 522 to separate from the air outlet valve 41.

[0108] Reference Figure 10As shown, the fastening screw 91 includes a shank 911 and a head 912. The shank 911 is connected to the head 912. The outer diameter of the shank 911 is smaller than the outer diameter of the head 912. The shank 911 passes through the through hole 4141 on the mounting arm 414 and is fastened to the protrusion mounting hole 52224. The head 912 abuts against the side of the mounting arm 414 opposite to the first rack 522.

[0109] In some embodiments of this application, reference is made to Figure 1 , Figure 6 , Figure 8 , Figure 14 As shown, the cover plate 43 is located on the side of the valve body 411 facing away from the drive device 5. On a plane perpendicular to the air outlet direction of the fresh air outlet 25, the projection of the valve body 411 on this plane is within the projection range of the cover plate 43 on this plane. In this way, the cover plate 43 can completely cover the air outlet valve 41 from the front side. The user can only see the cover plate 43 and not easily see the air outlet valve 41. There are no obvious observable gaps. The cover plate 43 can also serve as a decorative panel. Choosing an aesthetically pleasing cover plate 43 can enhance the user's experience of using the wall-mounted air conditioner 10.

[0110] In some embodiments of this application, reference is made to Figure 10 As shown, the valve body 411 is provided with a third snap-fit ​​structure 416, and the cover plate 43 is provided with a fourth snap-fit ​​structure 431. The fourth snap-fit ​​structure 431 is adapted to snap-fit ​​and fix with the third snap-fit ​​structure 416. One of the third snap-fit ​​structure 416 and the fourth snap-fit ​​structure 431 is a buckle, and the other is a slot. The third snap-fit ​​structure 416 and the fourth snap-fit ​​structure 431 are snap-fit ​​and fixed, thereby realizing the snap-fit ​​connection between the valve body 411 and the cover plate 43. The snap-fit ​​structure makes it convenient and quick to install and remove the cover plate 43 from the air outlet valve 41. When it is necessary to operate the fastening structure, the cover plate 43 can be quickly removed from the air outlet valve 41. When it is not necessary to operate the fastening structure, the cover plate 43 can be quickly installed on the air outlet valve 41.

[0111] For example, in Figure 10 In the example, the third snap-fit ​​structure 416 is a buckle, and the fourth snap-fit ​​structure 431 is a slot.

[0112] For example, in some embodiments not shown in the figure, the third snap-fit ​​structure 416 is a slot and the fourth snap-fit ​​structure 431 is a buckle.

[0113] In some embodiments of this application, reference is made to Figure 10As shown, both the valve body 411 and the cover plate 43 are tile-shaped plates. The middle portions of the valve body 411 and the cover plate 43 protrude forward from their upper and lower sides, respectively. Specifically, the middle portion of the valve body 411 protrudes forward from its upper and lower sides, and the middle portion of the cover plate 43 protrudes forward from its upper and lower sides. The valve body 411 has a third locking structure 416 on its upper and lower sides, and the cover plate 43 has a fourth locking structure 431 on its upper and lower sides. When it is necessary to disassemble the cover plate 43 from the outlet valve 41, a pressing force can be applied to the middle portion of the cover plate 43 towards the outlet valve 41. This pressing force causes the upper and lower sides of the cover plate 43 to tilt upwards, thereby separating the third locking structure 416 from the fourth locking structure 431. For example, the component of the pressing force in the air outlet direction can be 15N±3N. When the cover plate 43 produces an elastic deformation of 0.8mm (not exceeding 0.15% of the material's yield strength), the snap-fit ​​structures on the upper and lower sides of the cover plate 43 will trigger an automatic decoupling mechanism, causing the fourth snap-fit ​​structure 431 to separate from the third snap-fit ​​structure 416.

[0114] When it is necessary to install and fix the cover plate 43 to the air outlet valve 41, first attach the cover plate 43 to the air outlet valve 41, align the positions of the third snap-fit ​​structure 416 and the fourth snap-fit ​​structure 431, and apply a pressing pressure towards the air outlet valve 41 to the upper and lower sides of the cover plate 43. This pressing pressure causes the third snap-fit ​​structure 416 and the fourth snap-fit ​​structure 431 to snap and fix, thus achieving a fixed connection between the cover plate 43 and the air outlet valve 41.

[0115] In some embodiments of this application, reference is made to Figure 13 As shown, in the height direction of the wall-mounted air conditioner 10, the arc length of the cover plate 43 is L, and the shortest straight-line distance from the upper side to the lower side of the cover plate 43 is S, satisfying L / S≥1.025. For example, L / S can be 1.1, 1.2, 1.3, etc.

[0116] In some embodiments of this application, both the cover plate 43 and the air outlet valve 41 are plastic parts, such as HIPS (high impact polystyrene) plastic injection molded parts, so that the cover plate 43 can deform when subjected to pressure.

[0117] In some embodiments of this application, reference is made to Figures 7-10 As shown, the dimension of the valve body 411 in the length direction of the wall-mounted air conditioner 10 is greater than the dimension of the valve body 411 in the height direction of the wall-mounted air conditioner 10.

[0118] In some embodiments of this application, reference is made to Figures 7-10 As shown, the dimension of cover plate 43 in the length direction of wall-mounted air conditioner 10 is greater than the dimension of cover plate 43 in the height direction of wall-mounted air conditioner 10.

[0119] In some embodiments of this application, reference is made to Figure 10 As shown, the surface of the cover plate 43 facing the air outlet valve 41 is provided with a protrusion 432. The protrusion 432 is adapted to extend into the valve connecting cylinder 412 and is clamped to the inner wall of the valve connecting cylinder 412.

[0120] In some embodiments of this application, reference is made to Figures 15-17 As shown, the cover plate 43 is movably connected to the valve connecting cylinder 412. The fastening screw 91 of the valve connecting cylinder 412 and the connecting part 5222 is located in the hollow area of ​​the valve connecting cylinder 412. After the cover plate 43 is connected to the valve connecting cylinder 412, the cover plate 43 can cover the hollow area of ​​the valve connecting cylinder 412, thereby covering the fastening screw 91. When the user operates the cover plate 43, the cover plate 43 can be moved relative to the valve connecting cylinder 412.

[0121] In some embodiments of this application, reference is made to Figures 15-17 As shown, the cover plate 43 includes a cover plate body 433 and a second guide rail 434. The second guide rail 434 is connected to the cover plate body 433, and the length direction of the second guide rail 434 is the same as the length direction of the first rack body 5221. The valve connecting cylinder 412 is provided with a second guide groove 417, and the second guide rail 434 can move within the second guide groove 417. The cover plate body 433 is adapted to be interference-fitted with or separated from the valve connecting cylinder 412. When the cover plate body 433 moves relative to the valve connecting cylinder 412, the second guide rail 434 moves within the second guide groove 417, ensuring that the movement direction of the cover plate 43 is the length direction of the second guide rail 434, and the cover plate 43 is not easily tilted. When the cover plate body 433 is fixed relative to the valve connecting cylinder 412, the cover plate body 433 and the valve connecting cylinder 412 are interference-fitted, and the cover plate 43 is not easily separated from the air outlet valve 41.

[0122] In some embodiments of this application, reference is made to Figures 5-7 As shown, the fresh air housing 2 includes a first housing 21 and a second housing 22. The second housing 22 is detachably connected to the first housing 21, forming an air intake cavity between them. A fresh air inlet 24 communicates with the air intake cavity and is located on the first housing 21 and / or the second housing 22. When the fresh air inlet 24 is open, outdoor air can enter the air intake cavity through it. The separate design of the second housing 22 and the first housing 21 facilitates the installation and disassembly of components inside the air intake cavity.

[0123] The fresh air inlet 24 can be located solely on the first housing 21, solely on the second housing 22, or jointly enclosed by the first housing 21 and the second housing 22. For example, in Figure 5In the example, open half-openings are formed on the first shell 21 and the second shell 22 respectively, which are combined into a fresh air inlet 24, thereby facilitating processing or demolding and resulting in a low molding scrap rate.

[0124] The second housing 22 and the first housing 21 can be detachably connected by bolts, fasteners, clips, or other structures.

[0125] Reference Figures 5-7 As shown, the fresh air housing 2 also includes a third housing 23, which is detachably connected to the second housing 22. An air outlet cavity is formed between the third housing 23 and the second housing 22, and this air outlet cavity is connected to the air inlet cavity. A fresh air outlet 25 is located on the second housing 22 and / or the third housing 23, and is connected to the air outlet cavity. Outdoor air entering the air inlet cavity through the fresh air inlet 24 can enter the air outlet cavity. When the fresh air outlet 25 is opened, outdoor air in the air outlet cavity can be blown into the room through the fresh air outlet 25. The separate design of the third housing 23 and the second housing 22 facilitates the installation and disassembly of components inside the air outlet cavity.

[0126] The fresh air outlet 25 can be located solely on the second housing 22, solely on the third housing 23, or jointly enclosed by both the second housing 22 and the third housing 23. For example, in Figure 7 In one example, the fresh air outlet 25 is only provided on the third housing 23; in another example, in some embodiments not shown in the figure, the second housing 22 and the third housing 23 are respectively formed with open half openings to be combined into the fresh air outlet 25, which facilitates processing or demolding and results in a low scrap rate.

[0127] The third housing 23 and the second housing 22 can be detachably connected through bolts, fasteners, clips, or other structures.

[0128] Reference Figures 6-7 As shown, the wall-mounted air conditioner 10 also includes an air guide duct 6, which is installed at the fresh air outlet 25. The fresh air outlet 25 is connected to the casing outlet 11 through the air guide duct 6. The air guide duct 6 can guide the outdoor air blown out of the fresh air outlet 25 to the casing outlet 11, and then blow it into the room through the casing outlet 11.

[0129] In some embodiments of this application, the flow area of ​​the air guide duct 6 gradually increases in the air outlet direction. As a result, the air guide duct 6 can amplify the outdoor air blown out of the fresh air outlet 25, thereby reducing the wind speed reaching the air outlet 11 of the casing, so as to avoid causing discomfort to the user when the wind speed is too high.

[0130] In some embodiments of this application, the air guide duct 6 is constructed in a cylindrical shape, such as a conical tube or a square conical tube, with the small diameter end of the air guide duct 6 facing the fresh air outlet 25 and the large diameter end of the air guide duct 6 facing the air outlet 11 of the housing.

[0131] In some embodiments of this application, reference is made to Figures 3-7 As shown, the first housing 21, the second housing 22, and the third housing 23 are arranged sequentially along the length of the housing 1. The driving component 51 is installed on the first housing 21 and / or the second housing 22 to achieve the installation and fixation of the driving component 51. Specifically, the driving component 51 can be installed only on the first housing 21, only on the second housing 22, or simultaneously on both the first housing 21 and the second housing 22.

[0132] Reference Figures 6-7 As shown, the third housing 23 includes a first half-shell 231 and a second half-shell 232. The first half-shell 231 is detachably connected to the second half-shell 232, the first half-shell 231 is detachably connected to the second housing 22, and the second half-shell 232 is detachably connected to the second housing 22.

[0133] The first half-shell 231 and the second half-shell 232 can be detachably connected by bolts, fasteners, snaps, or other structures. The first half-shell 231 and the second shell 22 can be detachably connected by bolts, fasteners, snaps, or other structures. The second half-shell 232 and the second shell 22 can be detachably connected by bolts, fasteners, snaps, or other structures.

[0134] Reference Figure 2 , Figures 6-7 As shown, the fresh air housing 2 is also provided with a second fresh air outlet 26, and the housing 1 is provided with a second housing outlet 12. The second fresh air outlet 26 and the second housing outlet 12 are connected. When the fresh air fan rotates, outdoor air can enter the fresh air housing 2 from the fresh air inlet 24, and outdoor air entering the fresh air housing 2 can enter the room through the fresh air outlet 25, the housing outlet 11, the second fresh air outlet 26, and the second housing outlet 12.

[0135] The second fresh air outlet 26 can be located solely on the second housing 22, solely on the third housing 23, or it can be jointly enclosed by the second housing 22 and the third housing 23, for example, in... Figure 7 In one example, the second fresh air outlet 26 is only provided on the third housing 23; in another example, in some embodiments not shown in the figure, the second housing 22 and the third housing 23 are respectively formed with open half openings to be combined into the second fresh air outlet 26, which facilitates processing or demolding and results in a low scrap rate.

[0136] Reference Figure 2 , Figures 6-7 As shown, the second fresh air outlet 26 and the second air outlet 12 of the casing can be set on the top of the wall-mounted air conditioner 10 to achieve upward airflow.

[0137] In some embodiments not shown in the figure, the second fresh air outlet 26 and the second air outlet 12 of the casing can also be located at the front of the wall-mounted air conditioner 10 to achieve forward airflow.

[0138] In some embodiments of this application, reference is made to Figure 4 As shown, the housing 1 includes a sealing plate 13 and a mounting plate 16. The sealing plate 13 has an annular structure, and the mounting plate 16 is connected to the sealing plate 13. The mounting plate 16 has a mounting hole 161 for the valve connecting cylinder 412 to pass through. The housing air outlet 11 is surrounded by the sealing plate 13 and the mounting plate 16, and the air outlet end of the air guide duct 6 abuts against the sealing plate 13 and the mounting plate 16. The sealing plate 13 and the mounting plate 16 are used to seal the gap between the air guide duct 6 and the housing 1. Thus, the air guide duct 6 can better and more effectively guide the outdoor air blown out of the fresh air outlet 25 to the housing air outlet 11, preventing the outdoor air blown out of the fresh air outlet 25 from leaking into the housing 1.

[0139] In some embodiments of this application, when the air outlet valve 41 abuts against the sealing plate 13, the fresh air outlet 25 is closed, and the appearance of the wall-mounted air conditioner 10 is more aesthetically pleasing when the air outlet valve 41 abuts against the sealing plate 13; when the air outlet valve 41 separates from the sealing plate 13, the fresh air outlet 25 is opened, and fresh air is blown out from the space between the air outlet valve 41 and the sealing plate 13.

[0140] In some embodiments of this application, the wall-mounted air conditioner 10 further includes a purification component (not shown in the figure). The purification component is installed inside the air inlet cavity. When the fresh air fan rotates, outdoor air enters the fresh air housing 2 from the fresh air inlet 24, and the outdoor air entering the fresh air housing 2 is blown through the purification component and then enters the room from the fresh air outlet 25. The purification component is used to purify the fresh air blown into the room and improve the cleanliness of the indoor air.

[0141] The purification component is located at the axial air intake end of the fresh air fan. The fresh air flow can blow almost vertically over the purification component, which can further reduce the fresh air intake consumption and thus increase the fresh air volume.

[0142] In some embodiments of this application, reference is made to Figures 5-6 As shown, the fresh air housing 2 is also provided with an installation port 27, and the purification component can be detachably installed in the installation port 27. This facilitates the removal of the purification component when it is damaged or saturated, making it convenient for repair or replacement.

[0143] For example, combining Figures 5-7As shown, the mounting port 27 is formed between the first housing 21 and the second housing 22, and the purification component can be detachably assembled into the fresh air cavity through the mounting port 27. This allows the mounting port 27 to be set to a larger size, facilitating the installation of larger purification components. When the mounting port 27 is larger, it is formed by the enclosure between the first housing 21 and the second housing 22, with open semi-openings on both the first housing 21 and the second housing 22, facilitating processing or demolding and resulting in a low scrap rate.

[0144] For example, in the front-to-back direction of the wall-mounted air conditioner 10, the mounting port 27 is located on the front side of the wall-mounted air conditioner 10, so that the purification component can be disassembled without being interfered with by the duct connected to the fresh air intake, thus facilitating disassembly. For example, refer to Figures 1-6 As shown, the front side of the housing 1 is provided with an openable panel 81. When the panel 81 is opened or rotated upward, the mounting port 27 can be exposed, which facilitates the disassembly of the purification components.

[0145] It is also possible that in some designs, the installation port 27 is located at the bottom of the wall-mounted air conditioner 10.

[0146] In some embodiments of this application, reference is made to Figure 7 As shown, the second housing 22 is provided with an axial ventilation port 221, and the purification component includes a filter screen, which covers the axial ventilation port 221. The filter screen covers the entire air intake end of the fresh air fan, providing a large coverage area and excellent filtration effect. The filter screen design helps ensure sufficient contact area with the flowing air, while also being lightweight and producing low noise. For example, the filter screen may be made of HEPA mesh, thus possessing strong adsorption capacity and a strong filtration effect for dust in the air.

[0147] For example, the filter is plate-shaped, so the filter is thin overall and will not take up too much space when placed after the fresh air housing.

[0148] For example, the filter screen is square, which makes it easy to position and install the filter screen.

[0149] In some embodiments, the filter screen is a square mesh, with its side length greater than the diameter of the axial vent 221. The square mesh is easy to position during fixing, does not easily wobble after fixing, and is easy to process with minimal processing waste. By making the side length of the filter screen greater than the diameter of the axial vent 221, all fresh air entering the axial vent 221 can flow through the filter screen, resulting in high filtration cleanliness.

[0150] In some embodiments of this application, the wall-mounted air conditioner 10 further includes an indoor heat exchanger (not shown in the figure), which is disposed within a housing cavity. As described above, the indoor heat exchanger is a loop in the refrigerant circuit, and refrigerant flows inside the indoor heat exchanger to cool or heat the air flowing from the surface of the indoor heat exchanger. In the wall-mounted air conditioner 10, the indoor heat exchanger typically extends along the length of the casing 1.

[0151] For example, the indoor heat exchanger is a two-fold or three-fold heat exchanger, and each fold of the indoor heat exchanger is a plate-like structure extending along the length direction.

[0152] When the indoor heat exchanger is in cooling mode, causing condensation to form in the fresh air, the condensation can remain on the purification unit as the air flows through it, further preventing water from being blown out when the fresh air outlet 25 and the second fresh air outlet 26 are vented.

[0153] Reference Figure 14 As shown, the wall-mounted air conditioner 10 also includes a base 83 and a heat exchange fan. The base 83 is located within the accommodating cavity. The base 83 is an internal mounting support structure, on which the indoor heat exchanger and the fresh air casing 2 can be mounted. For example, a volute duct is formed on the base 83, and the heat exchange fan is located within the volute duct. In the wall-mounted air conditioner 10, the heat exchange fan typically extends along the length of the casing 1. After indoor air enters the casing 1, its flow direction is guided by the volute duct, ensuring minimal resistance when the indoor air flows through the indoor heat exchanger.

[0154] In some embodiments, the heat exchange fan is, for example, a cross-flow fan, which has low noise and large air volume, and the air velocity of the cross-flow fan is more evenly distributed along the axial direction of the fan, which is beneficial to increasing the air delivery distance and air delivery range. Moreover, when a cross-flow fan is used and is arranged along the length of the casing 1, it is beneficial for the driven airflow to flow through the entire indoor heat exchanger, ensuring the balance of heat exchange efficiency of each part of the indoor heat exchanger.

[0155] In some embodiments of this application, the wall-mounted air conditioner 10 further includes a second motor (not shown in the figure), which is disposed within the accommodating cavity. The second motor is used to drive a heat exchange fan to rotate, so that air exchanges heat with the indoor space inside the air conditioner.

[0156] In some embodiments of this application, the second motor is located at one end along the length of the heat exchange fan. This facilitates the installation and maintenance of the second motor, and the wall-mounted air conditioner 10 does not need to become excessively tall or thick due to the placement of the second motor. Here, the height direction of the wall-mounted air conditioner 10 is consistent with the vertical direction, and the thickness direction of the wall-mounted air conditioner 10 is consistent with the front-to-back direction.

[0157] The casing 1 has a heat exchange air inlet 14 and a heat exchange air outlet 15. By providing the heat exchange air outlet 14 and heat exchange air outlet 15 on the casing 1, indoor air can be drawn into the casing 1 through the heat exchange air inlet 14 when the heat exchange fan is running. After heat exchange between the indoor air and the indoor heat exchanger, the heat-exchanged air is delivered back into the room through the heat exchange air outlet 15. This allows for the regulation of the indoor ambient temperature. The indoor heat exchanger can function as an evaporator, providing cooling airflow to the indoor space through the heat exchange air outlet 15, or it can function as a condenser, providing heating airflow to the indoor space through the heat exchange air outlet 15.

[0158] In some embodiments of this application, reference is made to Figures 1-3 As shown, the wall-mounted air conditioner 10 also includes an air guide plate 82, which is disposed at the heat exchange air outlet 15 and is pivotally connected to the casing 1 or the base 83. When the air guide plate 82 rotates, it can adjust the air outlet direction at the heat exchange air outlet 15 to meet the different air blowing needs of users.

[0159] In some embodiments, refer to Figures 1-3 As shown, in the height direction of the wall-mounted air conditioner 10, the heat exchange air inlet 14 is located above the heat exchange air outlet 15, so that air can be drawn in from the top and discharged from the bottom.

[0160] For example, the height direction of the wall-mounted air conditioner 10 is the vertical direction.

[0161] Understandably, wall-mounted air conditioners 10 are typically installed on walls, and to avoid interfering with daily life, they are usually mounted high up. By designing the wall-mounted air conditioner 10 to blow heat exchange air from below, the blown heat exchange air is less likely to be obstructed by the ceiling or floor. This results in less resistance and energy loss during the airflow process, a wider air delivery range, and allows the heat exchange air to quickly circulate throughout the entire indoor space, improving heat exchange efficiency.

[0162] Reference Figures 1-3 As shown, the heat exchange air inlet 14 is located above the heat exchange air outlet 15. The heat exchange air inlet 14 can take in air from above, which can avoid taking in air from the heat exchange air outlet 15 and prevent the heat exchange air from being blown out of the heat exchange air outlet 15 and directly being sucked into the heat exchange air inlet 14, thus reducing the process of heat exchange air idling without participating in the indoor heat exchange.

[0163] In some embodiments, the heat exchange air inlet 14 is located on the top of the casing 1, i.e., in an area that is not visible to the user. Hiding the heat exchange air inlet 14 can improve the aesthetic appearance of the wall-mounted air conditioner 10.

[0164] In some embodiments, the heat exchange outlet 15 is located directly in front of the casing 1, that is, the heat exchange outlet 15 blows air towards the front of the wall-mounted air conditioner 10.

[0165] Understandably, the side of the wall-mounted air conditioner 10 that is connected to the wall is usually called the back or rear side, while the side opposite to the rear side is called the front side. Therefore, when the heat exchange outlet 15 is located directly in front of the casing 1, the air outlet is away from the wall, the air resistance is small, and the air delivery range is wide.

[0166] In some embodiments, the heat exchange air outlet 15 is located on the front side of the housing 1 and near the bottom, for example, the heat exchange air outlet 15 is located at the lower front corner of the housing 1. In this case, the heat exchange air blown out of the heat exchange air outlet 15 flows forward and downward at the same time, so that after being delivered a certain distance, the heat exchange air can sink and fall onto people or objects on the ground, so that people or objects on the ground can be in a suitable indoor environment as soon as possible.

[0167] In some embodiments of this application, the first housing 21 is disposed on the side of the second housing 22 away from the indoor heat exchanger, and the third housing 23 is disposed on the side of the second housing 22 closer to the indoor heat exchanger. The first housing 21, the second housing 22, and the third housing 23 are arranged in a reasonable manner, which can make full use of the space in the left and right direction of the wall-mounted air conditioner 10.

[0168] In some embodiments of this application, reference is made to Figures 5-8 As shown, the wall-mounted air conditioner 10 also includes an air inlet valve 42, which is used to open or close the fresh air inlet 24. The air outlet valve 41 opens the fresh air inlet 24, the air inlet valve 42 opens the fresh air outlet 25, and the fresh air fan rotates to allow outdoor air to enter the fresh air housing 2 from the fresh air inlet 24, and to allow outdoor air entering the fresh air housing 2 to enter the room through the fresh air outlet 25 and the housing outlet 11.

[0169] The second rack 523 meshes with the gear 521 for transmission. When the gear 521 rotates, it drives the second rack 523 to move. When the second rack 523 moves, it drives the air inlet valve 42 to move synchronously. The meshing transmission between the second rack 523 and the gear 521 is reliable, simple in structure, and easy to maintain.

[0170] In some embodiments of this application, reference is made to Figures 7-9As shown, gear 521 is a double gear, and gear 521 includes a first gear section 5211 and a second gear section 5212. The number of teeth in the first gear section 5211 is less than the number of teeth in the second gear section 5212. The first rack 522 meshes with the first gear section 5211. The transmission mechanism 52 also includes a second rack 523, which meshes with the second gear section 5212 for transmission. The second rack 523 is mounted on the air inlet valve 42. When the second gear section 5212 rotates to drive the second rack 523 to move, the second rack 523 drives the air inlet valve 42 to move, thereby opening or closing the fresh air inlet 24. When the first gear section 5211 rotates to drive the first rack 522 to move, the first rack 522 drives the air outlet valve 41 to rotate, thereby opening or closing the fresh air outlet 25.

[0171] Setting gear 521 as a double gear helps reduce the number of gears and assembly steps.

[0172] In some embodiments of this application, the air outlet 11 is located at the bottom of the housing 1 to guide the outdoor air blown out from the fresh air outlet 25 forward and downward into the room. This visualizes the fresh air function, giving users a direct visual experience of the fresh air supply.

[0173] Since the heat exchange air inlet 14 is located above the heat exchange air outlet 15, and the heat exchange air outlet 15 is relatively low on the casing 11, the casing air outlet 1111 blows fresh air from below, making the air outlet area of ​​the casing air outlet 1111 close to or even partially overlap with the air outlet area of ​​the heat exchange air outlet 15. This is beneficial for the fresh air to mix with the indoor air after heat exchange, improving the uniformity of the fresh air after mixing in the indoor air, and allowing the fresh air to absorb the cold or heat of the indoor air after heat exchange, making the fresh air temperature approach the indoor temperature and improving the comfort of airflow.

[0174] Furthermore, the air outlet 1111 of the casing is in the opposite direction to the air inlet 14 of the heat exchanger, so fresh air will not be drawn into the heat exchanger 14, reducing the proportion of fresh air intake at the heat exchanger 14, resulting in a larger total air volume of the wall-mounted air conditioner 1010 and improving the overall circulation efficiency of indoor air.

[0175] Furthermore, the air outlet 1111 is located below the wall-mounted air conditioner 1010, close to the living space, making it easy for people to observe the fresh air supply. This achieves a visual effect of fresh air supply, which helps improve the user experience.

[0176] For example, when the air outlet 1111 of the casing is located below the wall-mounted air conditioner 1010, it is usually located on the front side below the wall-mounted air conditioner 1010. This allows the fresh air to flow forward and downward, ensuring that the fresh air can reach the ground and also that the fresh air can reach a sufficiently long distance.
