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 related technologies, during the startup of a wall-mounted air conditioner indoor unit, the air intake and fresh air volume are among the standards for inspecting the quality of the air conditioner. After starting the air conditioner, the panel needs to be opened to facilitate the air intake and exhaust. The motor-driven transmission structure guides the panel. The motor and transmission structure need to be fixed to the outer casing to facilitate the movement of the panel. However, there is no limiting structure between the motor and transmission structure and the outer casing; they are only fastened with screws. When the screws are tightened, torque is generated, causing the motor and transmission mechanism to deviate from their predetermined positions. This results in the motor and transmission structure not being able to be effectively and securely installed on the outer casing, and also complicates the assembly of the wall-mounted air conditioner indoor unit.

[0018] The embodiments of this utility model are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[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. 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] Specifically, the drive assembly 2 includes a drive component 21, a reduction mechanism 22, and a transmission mechanism 23. The reduction mechanism 22 is disposed inside the outer cover 11 and connected to the drive component 21. The transmission mechanism 23 is connected to the reduction mechanism 22 and the front panel 12 respectively.

[0024] The driving component 21, the reduction mechanism 22, and the transmission mechanism 23 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.

[0025] The deceleration mechanism 22 is installed on the outer cover 11 by fasteners 3. A support part 111 is provided inside the outer cover 11. A first hook part 112 is provided on the side edge of the support part 111 away from the outer cover 11. The deceleration mechanism 22 is provided with a second hook part 221. The first hook part 112 and the second hook part 221 are hooked together.

[0026] It is understandable that the fastener 3 passes through the deceleration mechanism 22 and the outer cover 11, so that the deceleration mechanism 22 can be fixed on the outer cover 11. The outer cover 11 has a support part 111 inside. The support part 111 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. The support part 111 is provided with a first hook part 112, and the deceleration mechanism 22 is provided with a second hook part 221. Moreover, the first hook part 112 is located on the side of the support part 111 away from the outer cover 11, which facilitates the hooking and cooperation of the first hook part 112 and the second hook part 221. The deceleration mechanism 22 can be pre-installed on the support part 111, which simplifies the assembly process between the deceleration mechanism 22 and the support part 111.

[0027] During the process of fastener 3 passing through the deceleration mechanism 22 and the outer cover 11, an anti-torsional force is generated between the first hook part 112 and the second hook part 221. The hooking and cooperation of the first hook part 112 and the second hook part 221 can ensure that the deceleration mechanism 22 does not shift relative to the outer cover 11, and can ensure the firmness between the deceleration mechanism 22 and the outer cover 11, thereby saving the assembly time of the drive component 2 and simplifying the assembly process of the wall-mounted air conditioner indoor unit 100.

[0028] Therefore, by providing a support part 111 inside the outer cover 11, and the support part 111 is provided with a first hook part 112, and the deceleration mechanism 22 is provided with a second hook part 221, the first hook part 112 and the second hook part 221 are hooked together, and the deceleration mechanism 22 and the support part 111 are pre-installed through the hook part, the installation position of the deceleration mechanism 22 relative to the outer cover 11 can be limited. Then, fasteners 3 are passed through between the deceleration mechanism 22 and the outer cover 11 for fixation, which can prevent the deceleration mechanism 22 from shifting relative to the outer cover 11 when the fasteners 3 are tightened. This allows the deceleration mechanism 22 to be effectively and stably installed on the support part 111, and can also save the assembly time of the drive component 2, thereby simplifying the assembly process of the wall-mounted air conditioner indoor unit 100.

[0029] Optionally, the reduction mechanism 22 includes: a meshing first gear and a second gear, as well as meshing third gear and a fourth gear. The first gear is disposed on the drive member 21, the third gear rotates synchronously with the second gear, and the fourth gear is connected to the transmission mechanism 23.

[0030] It is understandable that the first gear, second gear, third gear and fourth gear are connected in sequence. The driving force of the driving component 21 is transmitted to the first gear. The second gear and the third gear rotate synchronously. After the first gear transmits the driving force to the second gear, the driving force undergoes a first-stage reduction. The driving force is then transmitted to the fourth gear through the third gear. The driving force undergoes a second-stage reduction. Finally, the fourth gear transmits the driving force with increased transmission torque to the transmission mechanism 23, so that the transmission mechanism 23 can drive the front panel 12 to move relative to the outer cover 11.

[0031] The third gear is located on one side of the second gear, and the third gear and the second gear are configured as a double gear. The driving force of the driving component 21 is transmitted to the first gear, and the first gear then transmits the driving force to the double gear. After reduction, the double gear transmits the force to the fourth gear, thus forming 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 Figures 5-8 As shown, the wall-mounted air conditioner indoor unit 100 also includes a filter screen, which is disposed inside the outer cover 11 and located between the air inlet 13 and the indoor heat exchanger, thereby filtering the air entering from the air inlet 13.

[0033] In other words, the filter is located inside the outer cover 11 and at the air inlet 13. The filter can filter the dust and impurities entering from the air inlet 13, thereby effectively filtering the dust and other particulate matter drawn in from the air inlet 13, which can directly improve the cleanliness of the air blown into the room, thus helping to improve indoor air quality.

[0034] The support part 111 is provided with a guide structure 117, which cooperates with the filter screen guide. The first hook part 112 is provided on the side of the guide structure 117 away from the outer cover 11.

[0035] It is understandable that the support part 111 is provided with a guide structure 117. The setting of the support part 111 facilitates the arrangement of the guide structure 117 and facilitates the guide structure 117 to guide the filter screen during installation. The guide structure 117 cooperates with the filter screen guide. When the user installs or resets the filter screen, there is no need to deliberately align it. Just push the filter screen along the guide structure 117 and it will be automatically guided to the correct position. This can ensure that the filter screen is completely and accurately installed in the designed position, thereby avoiding gaps caused by misalignment. The first hook part 112 is located on the side of the guide structure 117 away from the outer cover 11. This facilitates the hook-and-go cooperation between the first hook part 112 and the second hook part 221, which can simplify the assembly process between the deceleration mechanism 22 and the support part 111.

[0036] Optionally, such as Figures 5-10 As shown, the first hooking part 112 is constructed as a hooking edge, and the second hooking part 221 is constructed as a hooking hook, which engages with the hooking edge. This arrangement facilitates the engagement of the hooking hook and the hooking edge. The hooking edge on the support part 111 not only ensures the support effect of the support part 111, but also ensures that the hooking edge does not affect the movement of other components. Before the fastener 3 is tightened, the first hooking part 112 and the second hooking part 221 can pre-install the deceleration mechanism 22 and the support part 111. When the fastener 3 is tightened, the first hooking part 112 and the second hooking part 221 generate anti-torsional force, which can prevent the deceleration mechanism 22 from shifting relative to the outer cover 11 when the fastener 3 is tightened. This allows the deceleration mechanism 22 to be effectively and stably installed on the support part 111, and also saves the assembly time of the drive component 2, thereby simplifying the assembly process of the wall-mounted air conditioner indoor unit 100.

[0037] In particular, such as Figure 5 , Figure 6 , Figure 9 and Figure 10As shown, there are multiple hooks, which are spaced apart along the length of the hooking edge. This arrangement allows multiple hooks to engage with the hooking edge. Before the deceleration mechanism 22 and the support 111 are fastened, multiple hook structures and hooking edges are pre-installed, which facilitates the assembly and positioning between the deceleration mechanism 22 and the support 111. When the deceleration mechanism 22 and the support 111 are fastened, the fasteners 3 passing through the deceleration mechanism 22 and the outer cover 11 will generate torque, causing the deceleration mechanism 22 to deviate a certain amount relative to the outer cover 11. Multiple hook structures simultaneously pull against the hooking edge and generate anti-torsional force, which ensures the stability of the deceleration mechanism 22 relative to the outer cover 11 and prevents the deceleration mechanism 22 from deviating relative to the outer cover 11. This allows the deceleration mechanism 22 to be stably set on the outer cover 11, ensuring the stability of the deceleration mechanism 22's operation and saving assembly time for the wall-mounted air conditioner indoor unit 100.

[0038] Among them, such as Figure 7 and Figure 8 As shown, the hooking edge includes: a first hooking stage 113, a second hooking stage 114, and a third hooking stage 115. The second hooking stage 114 is connected to the first hooking stage 113, and the width of the second hooking stage 114 is smaller than the width of the first hooking stage 113. The third hooking stage 115 is connected to the second hooking stage 114, and the width of the third hooking stage 115 decreases in the direction away from the second hooking stage 114. Hooks are hooked to the second hooking stage 114 and the third hooking stage 115.

[0039] In other words, the hooking edge is divided into a first hooking stage 113, a second hooking stage 114, and a third hooking stage 115. The first hooking stage 113, the second hooking stage 114, and the third hooking stage 115 are connected sequentially from bottom to top, and a certain arc is formed between the first hooking stage 113, the second hooking stage 114, and the third hooking stage 115, thereby ensuring the strength of the first hooking stage 113, the second hooking stage 114, and the third hooking stage 115. The width of the first hooking stage 113, the second hooking stage 114, and the third hooking stage 115 decreases sequentially. The second hooking stage 114 and the third hooking stage 115 are respectively hooked with hooks. In this way, when the deceleration mechanism 22 and the outer cover 11 are pre-installed, multiple hooks can find the second hooking stage 114 and the third hooking stage 115 respectively, so that the second hooking stage 114 and the third hooking stage 115 can position the hooks, thereby ensuring that the deceleration mechanism 22 is set in the pre-installation position, and thus ensuring the stability between the deceleration mechanism 22 and the outer cover 11.

[0040] In particular, such as Figure 7 and Figure 8 As shown, a stepped surface 116 is formed at the connection between the first hook section and the second hook stage 114, and one of the plurality of hooks abuts against the stepped surface 116.

[0041] It is understandable that the lengths of the extensions of the first hook stage 113 and the second hook stage 114 relative to the guide structure 117 are different. The length of the extension of the first hook stage 113 relative to the guide structure 117 is greater than the length of the extension of the second hook stage 114 relative to the guide structure 117. A stepped surface 116 is formed between the first hook stage 113 and the second hook stage 114, which can create a clear difference between the first hook stage 113 and the second hook stage 114. One of the multiple hooks located at the edge abuts against the stepped surface 116, and the other hooks are then sequentially hooked onto the second hook stage 114 and the third hook section. This facilitates the pre-installation of the deceleration mechanism 22 and the outer cover 11, thereby saving the assembly time between the deceleration mechanism 22 and the outer cover 11.

[0042] Among them, such as Figure 7 and Figure 8 As shown, the length of the third hook stage 115 is less than the length of the second hook stage 114, and the length of the third hook stage 115 is greater than the length of another of the multiple hooks. This arrangement makes the third hook stage 115 and the second hook stage 114 clearly distinct. One of the hooks abuts against the step surface 116, while the other hook is attached to the third hook stage 115. This allows both the second hook stage 114 and the third hook stage 115 to bear the force of the hooks, ensuring the connection stability between the first hook part 112 and the second hook part 221. Furthermore, the length of the third hook stage 115 is greater than the length of the matching hook, ensuring that the hook smoothly engages with the third hook stage 115 without detaching, thus guaranteeing the connection stability between the first hook part 112 and the second hook part 221.

[0043] In addition, such as Figure 7 and Figure 8 As shown, the edge of the hooking edge is provided with a guide slope, which is guided and cooperates with the hooking hook. This arrangement facilitates the hooking hook to engage with the hooking edge through the guide slope, ensuring smooth engagement between the hooking edge and the hooking hook. It also facilitates the pre-installation between the deceleration mechanism 22 and the support part 111, thereby saving assembly time between the deceleration mechanism 22 and the outer cover 11.

[0044] In addition, such as Figure 10 As shown, the inner side of the hook is provided with a raised rib 222. The raised rib 222 abuts against the hook edge. The raised rib 222 can improve the structural strength of the inner side of the hook, improve the service life of the hook, ensure the hooking strength between the hook and the hook edge, and also generate friction between the raised rib 222 and the hook edge to prevent the hook from falling off relative to the hook edge. This can ensure the assembly stability between the deceleration mechanism 22 and the support part 111.

[0045] In addition, such as Figures 9-11 As shown, the wall-mounted air conditioner indoor unit 100 also includes: a mounting shell 223, which includes: a main shell 224 and a cover plate 225. One side of the main shell 224 is open, and a reduction mechanism 22 is disposed inside the main shell 224. A second hook part 221 is provided on the other edge of the main shell 224. The main shell 224 is installed on the outer cover 11 by fasteners 3. The cover plate 225 is disposed on one side of the main shell 224, and a driving member 21 is disposed on the side of the cover plate 225 away from the main shell 224.

[0046] In other words, the main shell 224 and the cover plate 225 constitute the main structure of the mounting shell 223. An opening is formed on one side of the main shell 224, which facilitates the installation of multiple reduction mechanisms 22 in the mounting shell 223. The mounting shell 223 can protect the multiple reduction mechanisms 22, thereby preventing the reduction mechanisms 22 from being bumped by other components and extending the service life of the reduction mechanisms 22. The cover plate 225 is placed over the opening of the main shell 224. The drive member 21 and the cover plate 225 are located on the left and right sides of the main shell 224, which can form a certain receiving cavity between the main shell 224 and the cover plate 225. The receiving cavity can accommodate the reduction mechanism 22, thereby facilitating the deceleration of the driving force of the drive member 21 through the reduction mechanism 22.

[0047] A second mounting part 221 is provided on the side of the main shell 224 away from the drive component 21. The second mounting part 221 is engaged with the first mounting part 112. This allows the main shell 224 to be pre-installed on the support part 111, thereby saving assembly time between the reduction mechanism 22 and the outer cover 11. The fastener 3 is located on the lower side of the main shell 224. After the first mounting part 112 and the second mounting part 221 are engaged, the fastener 3 will generate torque during the process of passing through the outer cover 11. Torsional force is generated between the first mounting part 112 and the second mounting part 221, which can firmly install the main shell 224 on the outer cover 11, thereby ensuring the stability of the main shell 224.

[0048] Optionally, the reduction mechanism 22 includes a planetary gear reduction mechanism 22. A part of the transmission mechanism 23 is connected to the reduction mechanism 22, and the other part of the transmission mechanism 23 is connected to the front panel 12. The power transmission of the drive component 21 passes through the reduction mechanism 22, the transmission mechanism 23, and the front panel 12 in sequence. The reduction mechanism 22 increases the torque of the driving force, so that the drive component 21 with lower power consumption can be used for driving. It can also reduce the size of the transmission mechanism 23, ensuring that the front panel 12 can move relative to the outer cover 11, thereby facilitating the air circulation of the wall-mounted air conditioner indoor unit 100. For example, the planetary gear reduction mechanism 22 has the characteristics of high efficiency, high precision, large load capacity, small size, low noise, and long service life.

[0049] The sun gear, planet carrier, planet gears and ring gear constitute the main body of the planetary gear reduction mechanism 22. The sun gear is located at the center of the planetary gear reduction mechanism 22. The sun gear is connected to the driving member 21. The driving force of the driving member 21 can be transmitted to the sun gear. Then the sun gear rotates at high speed around its own central axis, that is, the sun gear rotates on its own axis, thereby continuing to transmit the driving force.

[0050] The planet carrier is connected to the transmission mechanism 23. The planet gears are located on the planet carrier. The planet carrier can ensure the stability of the force. The planet gears mesh with the sun gear for transmission. The planet carrier drives the planet gears to revolve around the sun gear, and the planet gears also rotate on their own axes, thus forming a dual motion. This allows the planet gears to decelerate the force. The driving force of the drive component 21 is transmitted to the sun gear, and the sun gear then transmits the force to the planet gears. The planet gears increase the torque of the force transmission and then transmit it to the planet carrier and the transmission mechanism 23 in sequence.

[0051] The gear ring is fixed inside the outer cover 11 and is located on the outer circumference of the planetary gears. The gear ring meshes with the planetary gears, which allows the gear ring to provide a reaction force to the planetary gears, forcing the planetary gears to revolve while rotating on their own axis. This allows the planetary gears to achieve a deceleration effect on the force, thereby increasing the transmission torque of the force transmitted from the drive component 21 to the transmission mechanism 23 by the sun gear, planet carrier, planetary gears, and gear ring. This allows the use of a low-power drive component 21, reducing the power consumption of the drive component 21 and thus reducing the energy consumption of the wall-mounted air conditioner indoor unit 100.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] The indoor fan is configured to draw indoor air into the indoor unit through the third air inlet 13, and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the fourth air outlet 14. The indoor fan provides power for the airflow.
