Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a wall-mounted air conditioner indoor unit. Background Technology

[0002] In existing technology, during the startup of a wall-mounted air conditioner indoor unit, the air intake and fresh air volume are one of the standards for testing the quality of the air conditioner. After the air conditioner is turned on, the panel needs to be opened to facilitate the air intake and exhaust. The motor-driven transmission structure guides the panel movement, such as a stepper motor, which can open or close the control panel. However, the stepper motor is located inside the air conditioner, and the stepper motor itself, which is used to raise and lower the panel, is relatively large, occupying space inside the air conditioner. The transmission structure is also relatively large, which not only increases the power consumption of the stepper motor and the energy consumption of the air conditioner, but also increases the size of the air conditioner itself.

[0018] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0019] The following is for reference. Figures 1-11 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0020] like Figures 1-11 As shown, the wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model includes: a housing 1, an indoor heat exchanger and a drive assembly 2. The housing 1 includes an outer cover 11 and a front panel 12. The outer cover 11 has an air inlet 13 and an air outlet 14. The air inlet 13 is designed to facilitate the intake of indoor air, and the air outlet 14 blows the treated air back into the room, thus effectively forming an air circulation.

[0021] The front panel 12 is movably mounted on the front side of the outer cover 11. When the front panel 12 is fully opened, the entire air outlet 14 and the human sensor camera can be exposed. It can also increase the air intake, thereby increasing the air supply range and avoiding obstruction of the airflow at the air outlet 14.

[0022] The indoor heat exchanger is installed inside the outer casing 11, between the air inlet 13 and the air outlet 14, so that it can exchange heat with the air entering from the air inlet 13. The filter is installed inside the outer casing 11, between the air inlet 13 and the indoor heat exchanger, so that it can filter the air entering from the air inlet 13. This can ensure the cleanliness of the air entering the indoor unit 100 of the wall-mounted air conditioner and the cleanliness of the air blown out.

[0023] The drive assembly 2 is located inside the outer cover 11, which can protect the drive assembly 2 and extend its service life. The drive assembly 2 is connected to the front panel 12 and provides driving force to the front panel 12. This allows the front panel 12 to selectively open and close the front side of the outer cover 11, thereby enabling the front panel 12 to perform corresponding actions based on whether the wall-mounted air conditioner indoor unit 100 is turned on or off.

[0024] Specifically, the drive assembly 2 includes a drive member 21, a reduction mechanism 22, and a transmission mechanism 24. The reduction mechanism 22 is disposed inside the outer cover 11 and is connected to the drive member 21. The transmission mechanism 24 is connected to the reduction mechanism 22 and the front panel 12 respectively. The reduction mechanism 22 includes a plurality of reduction gear sets 221, which are sequentially transmitted between the drive member 21 and the transmission mechanism 24. Each reduction gear set 221 includes at least two meshing gears.

[0025] It is understandable that the driving component 21, the reduction mechanism 22, and the transmission mechanism 24 constitute the main body of the driving assembly 2. The reduction mechanism 22 is located inside the outer cover 11, which protects the reduction mechanism 22 from impacts by external forces, thereby extending its service life. Furthermore, the reduction mechanism 22 is connected to the driving component 21, allowing the driving force of the driving component 21 to be transmitted to the reduction mechanism 22, which increases the transmission torque of the driving force. For example, the driving component 21 can be a stepper motor, which features simple control, precise positioning, low cost, and fast response, making it convenient for the driving component 21 to provide driving force.

[0026] Multiple reduction gear sets 221 are connected between the drive component 21 and the transmission mechanism 24. The driving force of the drive component 21 is transmitted to the multiple reduction gear sets 221. The reduction gear sets 221 reduce the driving force and increase the transmission torque of the driving force. The reduced force is then transmitted to the transmission mechanism 24, which in turn drives the front panel 12 to move. Moreover, each reduction gear set 221 consists of at least two gears, and at least two gears mesh, which can ensure the effect of force transmission between gears.

[0027] The driving force of the drive component 21 is transmitted to at least two gears for deceleration. By reducing the driving force through at least two gears and increasing the transmission torque, the drive component 21, which consumes less power, can be used. This also reduces the size of the transmission mechanism 24, ensuring the front panel 12 can move relative to the outer casing 11, thus facilitating air circulation in the wall-mounted air conditioner indoor unit 100. For example, at least two meshing gears form a two-stage reduction. These at least two meshing gears are characterized by a compact structure, high space utilization, smooth transmission, high transmission efficiency, controllable losses, reasonable load distribution, and long service life.

[0028] Therefore, by setting a reduction mechanism 22 inside the outer casing 11, and connecting the drive component 21 and the transmission mechanism 24, the reduction mechanism 22 can increase the transmission torque of the force transmitted from the drive component 21 to the transmission mechanism 24. Under the premise of satisfying the movement of the front panel 12, the volume of the drive component 2 can be reduced, a low-power drive component 21 can be used, the power consumption of the drive component 21 can be reduced, the energy consumption of the wall-mounted air conditioner indoor unit 100 can be reduced, and a smaller drive component 21 can be used, reducing the space occupied by the drive component 21 inside the wall-mounted air conditioner indoor unit 100 and ensuring the volume of other components.

[0029] Among them, such as Figure 9 and Figure 10 As shown, the multiple reduction gear sets 221 include: a first reduction gear set 222 and a second reduction gear set 223. The first reduction gear set 222 includes a meshing first gear 224 and a second gear 225. The first gear 224 is disposed on the drive member 21. The second reduction gear set 223 includes a meshing third gear 226 and a fourth gear 227. The third gear 226 rotates synchronously with the second gear 225, and the fourth gear 227 is connected to the transmission mechanism 24.

[0030] It is understandable that the first gear 224, the second gear 225, the third gear 226, and the fourth gear 227 are connected in sequence for transmission. The driving force of the driving component 21 is transmitted to the first gear 224. The second gear 225 and the third gear 226 rotate synchronously. After the first gear 224 transmits the driving force to the second gear 225, the driving force undergoes a first-stage reduction. The driving force is then transmitted to the fourth gear 227 through the third gear 226, where it undergoes a second-stage reduction. Finally, the fourth gear 227 transmits the driving force with increased transmission torque to the transmission mechanism 24, thereby enabling the transmission mechanism 24 to drive the front panel 12 to move relative to the outer cover 11.

[0031] Optionally, such as Figure 9 and Figure 10 As shown, the third gear 226 is located on one side of the second gear 225, and the third gear 226 and the second gear 225 are configured as a double gear. The driving force of the driving member 21 is transmitted to the first gear 224, and the first gear 224 then transmits the driving force to the double gear. After reduction, the double gear transmits the force to the fourth gear 227. This can form a two-stage reduction. The double gear can simplify the transmission chain, improve transmission efficiency, reduce assembly errors, make the transmission smoother, ensure transmission torque, reduce the number of parts, and reduce costs.

[0032] In addition, such as Figure 7 , Figure 9 and Figure 10As shown, the transmission mechanism 24 includes: a rocker arm 241 and a panel connector 242. A fourth gear 227 is disposed at one end of the rocker arm 241. The panel connector 242 is disposed on the front panel 12. One end of the panel connector 242 is connected to the other end of the rocker arm 241. The other end of the panel connector 242 is slidably disposed on the outer cover 11.

[0033] It is understood that the rocker arm 241 is located between the reduction mechanism 22 and the panel connector 242. The driving force of the drive member 21 is transmitted to the rocker arm 241 after being reduced by the reduction mechanism 22. The rocker arm 241 drives the panel connector 242 to move. The panel connector 242 is set on the front panel 12. One end of the panel connector 242 is connected to the front panel 12, and the other end is slidably connected to the outer cover 11. This allows the front panel 12 to move relative to the outer cover 11. Moreover, the middle part of the rocker arm 241 is bent, which can limit the range of movement of the front panel 12 relative to the outer cover 11, thereby limiting the space in which the front panel 12 opens relative to the outer cover 11.

[0034] In particular, such as Figure 9 and Figure 10 As shown, the fourth gear 227 is constructed as an incomplete gear, and it is integrally formed on one end of the rocker arm 241. For example, the fourth gear 227 is a sector gear that meshes with the third gear 226, thereby enabling a transmission connection between the third gear 226 and the fourth gear 227. The fourth gear 227 is located at the end of the rocker arm 241 near the third gear 226, which restricts the range of motion of the rocker arm 241, thereby limiting the range of motion of the front panel 12 relative to the outer cover 11.

[0035] In addition, such as Figure 5 and Figure 6 As shown, a slide rail is installed on the front side of the outer cover 11, and the slide rail forms an arc-shaped groove 15. The other end of the panel connector 242 is slidably disposed in the groove 15.

[0036] In other words, a slide rail is provided on the side of the outer cover 11 facing the transmission mechanism 24, and the slide rail forms a slide groove 15. This facilitates the sliding of one end of the panel connector 242 in the slide groove 15, thereby allowing the slide groove 15 to restrict the movement direction of the panel connector 242. Moreover, the slide groove 15 is arc-shaped, so that the slide groove 15 corresponds to the bent rocker arm 241, which can limit the range of movement of the front panel 12 relative to the outer cover 11, thereby limiting the space in which the front panel 12 opens relative to the outer cover 11.

[0037] In addition, such as Figure 7 , Figure 8 and Figure 11As shown, the reduction mechanism 22 includes: a mounting housing 228, which is disposed on the outer cover 11; a driving component 21 disposed outside the mounting housing 228; and multiple reduction gear sets 221 disposed inside the mounting housing 228.

[0038] Understandably, the mounting housing 228 is located inside the outer cover 11, which protects the mounting housing 228 and prevents it from interfering with the operation of other components. The drive unit 21 is located on one side of the first mounting housing 228, so that the mounting housing 228 does not interfere with the drive unit 21 providing driving force. Multiple reduction gear sets 221 are located inside the mounting housing 228. The mounting housing 228 can protect the multiple reduction gear sets 221 from external impacts, extend the service life of the multiple reduction gear sets 221, and optimize the internal space of the wall-mounted air conditioner indoor unit 100.

[0039] Among them, such as Figure 9 and Figure 11 As shown, the mounting housing 228 includes: a main housing 229, a first cover plate 230 and a second cover plate 231. Multiple reduction gear sets 221 are disposed inside the main housing 229. The first cover plate 230 is disposed on the side of the main housing 229 away from the transmission mechanism 24. The driving member 21 is disposed on the side of the first cover plate 230 away from the main housing 229. The second cover plate 231 is disposed on the side of the main housing 229 close to the transmission mechanism 24. The second cover plate 231 and the first cover plate 230 are disposed opposite to each other.

[0040] In other words, the main shell 229, the first cover plate 230, and the second cover plate 231 constitute the main body of the mounting shell 228. The main shell 229 is located inside the outer cover 11, and multiple reduction gear sets 221 are located inside the main shell 229. This facilitates the driving force to move the front panel 12 relative to the outer cover 11 after being reduced by multiple reduction gear sets 221. The first cover plate 230 and the second cover plate 231 are located on the left and right sides of the main shell 229. The driving component 21 is located on the side of the first cover plate 230 away from the main shell 229, and the transmission mechanism 24 is located on the side of the second cover plate 231 away from the main shell 229. The driving force of the driving component 21 passes through multiple reduction gear sets 221 inside the main shell 229. After the multiple reduction gear sets 221 increase the transmission torque of the driving force, the driving force is transmitted to the driving mechanism, and the driving mechanism then drives the front panel 12 to move relative to the outer cover 11.

[0041] In addition, such as Figure 11As shown, the main housing 229 includes: a partition 232, a first outer peripheral wall 233 and a second outer peripheral wall 234. The first outer peripheral wall 233 is disposed on the side of the partition 232 away from the transmission mechanism 24, and the first outer peripheral wall 233 and the partition 232 form a first mounting cavity. The first reduction gear set 222 is disposed in the first mounting cavity. The first cover plate 230 is disposed on the first outer peripheral wall 233. The second outer peripheral wall 234 is disposed on the other side of the partition 232, and the second outer peripheral wall 234 and the partition 232 form a second mounting cavity. The second reduction gear is disposed in the second mounting cavity. The second cover plate 231 is disposed on the second outer peripheral wall 234. An opening 235 for the transmission mechanism 24 to extend is formed on the front side of the second outer peripheral wall 234.

[0042] It is understood that the partition 232, the first outer peripheral wall 233, and the second outer peripheral wall 234 constitute the main structure of the main shell 229. The first outer peripheral wall 233 is located on the side of the partition 232 facing the drive member 21, and the second outer peripheral wall 234 is located on the side of the partition 232 facing the transmission mechanism 24. The first cover plate 230 is placed on one side of the first outer peripheral wall 233, so that a first mounting cavity is formed between the first cover plate 230, the first outer peripheral wall 233, and the partition 232. The first mounting cavity can provide a mounting position for the first reduction gear set 222, thereby facilitating the transmission of driving force by the first reduction gear set 222. The second cover plate 231 is placed on one side of the second outer peripheral wall 234, so that a second mounting cavity is formed between the second cover plate 231, the first outer peripheral wall 233, and the partition 232. The second mounting cavity can provide a mounting position for the second reduction gear set 223, thereby facilitating the transmission of driving force by the second reduction gear set 223.

[0043] The first outer peripheral wall 233 and the second outer peripheral wall 234 are arranged adjacent to each other on the left and right, and the first mounting cavity and the second mounting cavity are arranged adjacent to each other on the left and right. This allows the first reduction gear set 222 and the second reduction gear set 223 to be close to each other and facilitates the transmission of driving force. An opening 235 is provided on one side of the second outer peripheral wall 234, and a part of the transmission mechanism 24 can pass through the opening 235. This allows the second outer peripheral wall 234 to restrict the range of motion of the transmission mechanism 24, so that the driving force can drive the transmission mechanism 24 to move the front panel 12.

[0044] In addition, such as Figure 4 As shown, a support part 16 is provided inside the outer cover 11, and a deceleration mechanism 22 is respectively provided in the outer cover 11 and the support part 16. The support part 16 can not only limit the deceleration mechanism 22, but also provide installation guidance for the deceleration mechanism 22, thereby facilitating the transmission of driving force by the deceleration mechanism 22.

[0045] In addition, such as Figure 4 and Figure 7As shown, the driving force of the drive component 21 is reduced by the reduction mechanism 22 and then transmitted to the transmission rod 25. At least two transmission mechanisms 24 on the transmission rod 25 are respectively connected to the front panel 12, and the at least two transmission mechanisms 24 are arranged at intervals along the length of the transmission rod 25. This makes the front panel 12 connected to the transmission mechanism 24 move more smoothly, ensures that the opening of the front panel 12 relative to the outer cover 11 is uniform, makes the air intake of the wall-mounted air conditioner indoor unit 100 uniform, and facilitates the air exchange of the wall-mounted air conditioner indoor unit 100.

[0046] In particular, such as Figure 4 and Figure 7 As shown, the drive component 21, the reduction mechanism 22 and the transmission mechanism 24 are distributed at intervals in the left and right directions. This optimizes the layout of the drive assembly 2 and facilitates the transmission of driving force. The drive component 21 is located on the side of the reduction mechanism 22 away from the indoor heat exchanger, so that the drive component 21 and the indoor heat exchanger do not interfere with each other, thereby facilitating the drive component 21 to provide driving force.

[0047] An air conditioner includes an indoor unit and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit includes an indoor heat exchanger and an indoor fan. The outdoor unit includes a compressor, a four-way valve, an outdoor heat exchanger, an outdoor fan, and an expansion valve. The compressor, outdoor heat exchanger, expansion valve, and indoor heat exchanger, connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor and indoor heat exchangers to achieve the cooling or heating mode of the cabinet air conditioner. The compressor is configured to compress the refrigerant, so that the low-pressure refrigerant is compressed into high-pressure refrigerant.

[0048] The outdoor heat exchanger is configured to exchange heat between outdoor air and refrigerant transported within it. For example, in the cooling mode of a cabinet air conditioner, the outdoor heat exchanger functions 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 cabinet air conditioner, the outdoor heat exchanger functions as an evaporator, causing the depressurized refrigerant to absorb heat from the outdoor air and evaporate.

[0049] In some embodiments, the outdoor heat exchanger further includes fins to increase the contact area between the outdoor air and the refrigerant transported in the outdoor heat exchanger, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0050] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet 13 and discharge the outdoor air, after heat exchange with the outdoor heat exchanger, through the outdoor air outlet 14. The outdoor fan provides power for the flow of outdoor air.

[0051] An expansion valve connects the outdoor and indoor heat exchangers. The opening degree of the expansion valve regulates the refrigerant pressure flowing through both heat exchangers, thereby regulating the refrigerant flow rate between them. The flow rate and pressure of the refrigerant flowing between the outdoor and indoor heat exchangers affect their heat exchange performance. The expansion valve can be an electronic valve, and its opening degree is adjustable to control the refrigerant flow rate and pressure.

[0052] The four-way valve is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the cabinet air conditioner can perform cooling mode or heating mode.

[0053] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of a cabinet air conditioner, the indoor heat exchanger operates as an evaporator, causing the refrigerant, after dissipating heat from the outdoor heat exchanger, to absorb heat from the indoor air and evaporate. In the heating mode of the cabinet air conditioner, the indoor heat exchanger operates as a condenser, causing the refrigerant, after absorbing heat from the outdoor heat exchanger, to dissipate heat to the indoor air and condense.

[0054] In some embodiments, the indoor heat exchanger further includes fins to increase the contact area between indoor air and the refrigerant transported in the indoor heat exchanger, thereby improving the heat exchange efficiency between indoor air and the refrigerant.

[0055] The indoor fan is configured to draw indoor air into the indoor unit through its air inlet and expel the air, after heat exchange with the indoor heat exchanger, through its air outlet. The indoor fan provides the power for the airflow.
