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] Household air conditioning units can be divided into two types based on their structure: modular air conditioners and split-type air conditioners. Among them, the most common types of split-type air conditioners are floor-standing and wall-mounted air conditioners. Wall-mounted air conditioners are widely popular because of their compact structure and ability to save floor space.

[0003] The indoor casing of a wall-mounted air conditioner contains a heat exchanger, filter, and motor. The motor drives a cross-flow fan to rotate, which blows air out of the indoor unit, creating a negative pressure difference. Air from the room enters the indoor unit through the upper grille, passes through the filter, exchanges heat with the heat exchanger, and is then blown out through the air outlet, thus completing the cycle. The filter, by filtering dust from the air, provides clean air and also protects the air conditioner.

[0004] In existing technologies, the air intake at the top of the casing has limited capacity. Some wall-mounted air conditioners employ a movable front panel design, which uses a drive assembly to open the front of the casing to supplement air intake, effectively increasing the air volume. However, the placement of the drive assembly within the casing can interfere with the filter's guide rail structure, affecting filter installation. Utility Model Content

[0020] 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.

[0021] The following is for reference. Figures 1-15 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0022] Reference Figures 1-5 As shown, the wall-mounted air conditioner indoor unit 100 of this utility model embodiment includes: a casing 1, an indoor heat exchanger, a filter, and a drive assembly 2. The casing 1 includes an outer cover 11 and a front panel 12. The outer cover 11 has an air inlet 111 and an air outlet 112. The air inlet 111 can be located at the top of the outer cover 11, and the air outlet 112 can be located at the bottom front side of the outer cover 11. The arrangement of the air inlet 111 facilitates the intake of indoor air, and the air outlet 112 blows the treated air back into the room, thus effectively forming an air circulation.

[0023] The front panel 12 is movably disposed on the front side of the outer cover 11. When the front panel 12 is in the closed position, the front panel 12 covers the front side of the outer cover 11 and blocks the air outlet 112. When the front panel 12 is in the open position, the front panel 12 opens the front side of the outer cover 11, which allows the indoor space to take in air from the front side of the outer cover 11, thereby enabling supplemental air, increasing the air intake volume, meeting the current air intake demand, and exposing the entire air outlet 112, thereby increasing the air supply range and avoiding the front panel 12 from obstructing the airflow of the air outlet 112.

[0024] Furthermore, the indoor heat exchanger is housed within the outer casing 11, which provides both protection and a mounting location for the indoor heat exchanger. Located between the air inlet 111 and the air outlet 112, the indoor heat exchanger exchanges heat with the air entering through the air inlet 111. This results in a more uniform air temperature after passing through the indoor heat exchanger, preventing localized overcooling or overheating and thus improving the uniformity of the indoor temperature field.

[0025] Furthermore, a filter is disposed inside the outer cover 11, located between the air inlet 111 and the indoor heat exchanger, thereby filtering the air entering from the air inlet 111. In this way, the filter can effectively filter dust and other particulate matter drawn in from the air inlet 111, directly improving the cleanliness of the air blown into the room and thus helping to improve indoor air quality.

[0026] Furthermore, the drive assembly 2 is located inside the outer cover 11 and is connected to the front panel 12. This allows the front panel 12 to selectively open and close the front side of the outer cover 11. In this way, the drive assembly 2 can provide power for the front panel 12 to open and close, and can also control the size of the opening on the front side of the outer cover 11, thereby adjusting the air intake range.

[0027] A first support portion 3 is provided inside the outer cover 11. The first support portion 3 is provided with a first guide structure 31. The first support portion 3 facilitates the arrangement of the first guide structure 31 and allows the first guide structure 31 to guide the filter screen during installation. The drive assembly 2 is provided with a second guide structure 21. The drive assembly 2 provides an installation position for the second guide structure 21. The second guide structure 21 can also make reasonable use of the space of the drive assembly 2. When the drive assembly 2 is installed, it can avoid the second guide structure 21 from obstructing the drive assembly 2, thereby improving the installation speed of the drive assembly 2.

[0028] Furthermore, the second guide structure 21 is disposed along the length extension direction of the first guide structure 31, so that the second guide structure 21 and the first guide structure 31 can work together to guide the filter screen. The first guide structure 31 and the second guide structure 21 respectively cooperate 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 first guide structure 31 and the second guide structure 21, 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 during installation.

[0029] The first support portion 3 has a first mounting groove 32 that opens toward the inside of the outer cover 11. The first mounting groove 32 extends toward the inside of the outer cover 11. A part of the drive component 2 is disposed in the first mounting groove 32. In this way, the first mounting groove 32 can provide installation space for a part of the drive component 2, thereby avoiding the drive component 2 from occupying a large space inside the outer cover 11.

[0030] Furthermore, a portion of the drive assembly 2 is provided with a second guide structure 21, which is located between the first guide structures 31 on both sides of the first mounting groove 32. The position of the second guide structure 21 corresponds to that of the drive assembly 2. By integrating the second guide structure 21 with the drive assembly 2, the second guide structure 21 can avoid obstructing the drive assembly 2 during installation, thus facilitating the installation of the drive assembly 2.

[0031] Therefore, a second guide structure 21 is provided in part of the drive component 2 in the wall-mounted air conditioner indoor unit 100. During the installation of the drive component 2, the second guide structure 21 can avoid obstructing the drive component 2 and can also improve the installation speed of the drive component 2.

[0032] According to some embodiments of this utility model, such as Figures 3-6 As shown, the portion of the first guide structure 31 adjacent to the second guide structure 21 forms a first guide surface 311. The first guide surface 311 not only provides support for the filter screen, but also provides guidance for the installation of the filter screen, thereby facilitating the accurate installation of the filter screen onto the first guide surface 311.

[0033] Furthermore, the second guide structure 21 is provided with a second guide surface 211, which not only provides support for the filter screen but also guides its installation. Moreover, the first guide surface 311 and the second guide surface 211 respectively cooperate with the filter screen guide, and the first guide surface 311 and the second guide surface 211 are located within the same arc-shaped surface. Thus, during installation or removal, the filter screen can smoothly slide in or out along this arc, with a smooth movement trajectory, without any jamming or abrupt changes.

[0034] Also, such as Figure 6 As shown, since the first guide surface 311 and the second guide surface 211 are on the same arc surface, their spatial position and curvature are consistent, which can ensure that the guide path of the filter screen on the left and right (or up and down) sides is completely symmetrical.

[0035] According to some embodiments of this utility model, such as Figures 4-8As shown, the drive assembly 2 includes: a mounting housing 22, a drive component 23, a reduction mechanism 24, and a transmission mechanism 25. The drive component 23 is disposed in the mounting housing 22, which provides a mounting position for the drive component 23, facilitating its installation. The reduction mechanism 24 is disposed in the mounting housing 22 and can operate within the housing, thus partially shielding the noise generated by the reduction mechanism 24 and reducing its transmission into the room.

[0036] Furthermore, the reduction mechanism 24 is connected to the drive component 23, which can provide power to the reduction mechanism 24, thereby driving the reduction mechanism 24 to operate. The reduction mechanism 24 can change the output speed of the drive component 23, thereby meeting the required speed for operation.

[0037] Furthermore, the conveying mechanism 25 is connected to the deceleration mechanism 24 and the front panel 12 respectively. The deceleration mechanism 24 is located between the conveying mechanism 25 and the front panel 12. The deceleration mechanism 24 can drive the conveying mechanism 25 to rotate. Since the conveying mechanism 25 is connected to the front panel 12, the conveying mechanism 25 can drive the front panel 12 to move up or down, thereby realizing the opening and closing of the front panel 12.

[0038] A portion of the mounting housing 22 is disposed within the first mounting groove 32, which provides installation space for the portion of the mounting housing 22, facilitating its insertion into the groove. A portion of the mounting housing 22 is provided with a second guide structure 21, which is a convex arc-shaped structure. This guide structure not only provides guidance for the installation of the filter screen but also prevents it from obstructing the installation of the mounting housing 22 of the drive assembly 2.

[0039] According to some embodiments of this utility model, such as Figures 4-8 As shown, the drive component 23 is disposed on one side of the mounting housing 22, close to the outer cover 11, which prevents the drive component 23 from interfering with other parts. Furthermore, the reduction mechanism 24 is disposed inside the mounting housing 22, and the second guide structure 21 is disposed on the other side of the mounting housing 22 opposite to the drive component 23. This facilitates the cooperation between the second guide structure 21 and the filter screen, and also provides a larger installation space for both, thus facilitating the installation of the filter screen and the second guide structure 21.

[0040] According to some embodiments of this utility model, such as Figures 4-8As shown, the mounting housing 22 includes a main housing 221 and a cover plate 222. One side of the main housing 221 is open, which facilitates the installation of the cover plate 222. The reduction mechanism 24 is disposed inside the main housing 221, and the cover plate 222 is disposed on one side of the main housing 221. In this way, the cover plate 222 can cover one side of the main housing 221 and can also be easily disassembled, thereby facilitating its maintenance.

[0041] Furthermore, the drive component 23 is located on the side of the cover plate 222 opposite to the main shell 221. In this way, the drive component 23 can make reasonable use of the space of the main shell 221 and also provide a certain installation space for the cover plate 222. The second guide structure 21 is integrally formed on the other side of the main shell 221 opposite to the drive component 23. This can improve the strength of the second guide structure 21 and make the second guide structure 21 more load-bearing and less prone to deformation or breakage due to external forces.

[0042] According to some embodiments of this utility model, such as Figures 4-8 As shown, a portion of the mounting housing 22 is provided with a third guide structure 223. The second guide structure 21 and the third guide structure 223 are spaced apart in the depth direction of the first mounting groove 32. A portion of the filter screen can be guided and cooperated with the second guide structure 21 and the third guide structure 223 respectively.

[0043] Furthermore, the filter screen is inserted between the second guide structure 21 and the third guide structure 223. The second guide structure 21 and the third guide structure 223 can jointly provide a certain guiding space for the filter screen, thereby facilitating the installation of the filter screen.

[0044] According to some embodiments of this utility model, such as Figures 4-8 As shown, the wall-mounted air conditioner indoor unit 100 also includes: a transmission rod 4, and a reduction mechanism 24 having an output end 241. A portion of the output end 241 is connected to the transmission rod 4. Thus, the reduction mechanism 24 can transmit power to the transmission rod 4 through the output end 241, thereby driving the transmission rod 4 to rotate.

[0045] Furthermore, the mounting housing 22 is provided with a limiting flange 224 surrounding a portion of the output end 241. The limiting flange 224 can wrap around a portion of the output end 241, thus preventing a portion of the output end 241 from colliding with other parts during installation.

[0046] Furthermore, a portion of the side of the limiting flange 224 near the second guide structure 21 forms a third guide structure 223. In this way, the portion of the side of the limiting flange 224 near the second guide structure 21 can not only wrap a part of the output end 241, but also serve as a guide structure for the filter screen. The third guide structure 223 and the second guide structure 21 can work together to serve as guide structures for the filter screen, thereby making the filter screen more accurately guided during installation.

[0047] Furthermore, another part of the side of the limiting flange 224 is matched with the wall of the first mounting groove 32 for limiting, so as to limit the limiting flange 224 and thus to position and install the limiting flange 224.

[0048] According to some embodiments of this utility model, such as Figures 4-8 As shown, at least two first support parts 3 are provided inside the outer cover 11, and at least two drive components 2 are provided, with at least two first support parts 3 and at least two drive components 2 corresponding one-to-one.

[0049] The number of drive components 2 can be set to two. Correspondingly, two first support parts 3 are provided inside the outer cover 11. The drive components 2 can be installed in the first support parts 3. The first support parts 3 can provide support for the drive components 2, thereby facilitating the installation of the drive components 2 and saving space.

[0050] According to some embodiments of this utility model, such as Figures 4-10 As shown, the wall-mounted air conditioner indoor unit 100 also includes a transmission rod 4, which is connected between two adjacent drive components 2. When one drive component 2 is working, it can transmit power to the other drive component 2 through the transmission rod 4, so that the two drive components 2 can rotate synchronously. Thus, the two drive components 2 can simultaneously transmit power to the front panel 12 through the transmission mechanism 25, thereby enabling the front panel 12 to rise and fall.

[0051] The outer cover 11 is provided with a second support part 5 and a support seat 7. The second support part 5 and the support seat 7 are located in the middle area of ​​the outer cover 11 along its length. In this way, the second support part 5 and the support seat 7 can further play a supporting role, thereby strengthening the strength of the middle area of ​​the outer cover 11.

[0052] Furthermore, the second support part 5 is spaced apart from the first support part 3, which makes the support force of the second support part 5 and the first support part 3 on the outer cover 11 more uniform, and also avoids interference between the second support part 5 and the first support part 3.

[0053] The second support portion 5 is provided with a fourth guide structure 51, which can guide the filter screen during vertical installation. Furthermore, the second support portion 5 forms a second mounting groove 62 that opens towards the inside of the outer cover 11. The support base 7 is disposed within the second mounting groove 62, thus providing a certain installation space for the support base 7, facilitating its installation.

[0054] Furthermore, the support base 7 is provided with a fifth guide structure 71, which is located between the fourth guide structures 51 on both sides of the second mounting groove 62. The fourth guide structures 51 and the fifth guide structure 71 respectively cooperate with the filter screen guide. Specifically, when the drive assembly 2 is installed, the support base 7 containing the fifth guide structure 71 is not installed to the second support part 5, so that the fifth guide structure 71 will not obstruct the drive assembly 2 during installation.

[0055] According to some embodiments of this utility model, such as Figures 10-13 As shown, the portion of the fourth guide structure 51 adjacent to the fifth guide structure 71 forms a third guide surface 511. The third guide surface 511 not only provides support for the middle area of ​​the filter screen, but also provides guidance for the installation of the filter screen, thereby facilitating the accurate installation of the filter screen onto the third guide surface 511.

[0056] Furthermore, the fifth guide structure 71 is equipped with a fourth guide surface 711. This fourth guide surface 711 not only provides support for the filter screen but also guides its installation. The third guide surface 511 and the fourth guide surface 711 respectively cooperate with the filter screen guide, and both are located within the same arc-shaped surface. Thus, during installation or removal, the filter screen can smoothly slide in or out along this arc, with a smooth movement trajectory, without any jamming or abrupt changes.

[0057] Furthermore, the air conditioner includes a wall-mounted indoor unit 100 and an outdoor unit, which are connected by pipes to transfer refrigerant. The indoor unit 100 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 air conditioner's cooling or heating mode. The compressor is configured to compress the refrigerant, thereby compressing the low-pressure refrigerant into a high-pressure refrigerant.

[0058] 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.

[0059] 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.

[0060] The outdoor fan is configured to draw outdoor air into the outdoor unit through the outdoor air inlet and expel the outdoor air, after it has been heated by the outdoor heat exchanger, through the outdoor air outlet. The outdoor fan provides power for the flow of outdoor air.

[0061] 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.

[0062] 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.

[0063] The indoor heat exchanger is configured to exchange heat between indoor air and refrigerant transported within it. For example, in the cooling mode of the 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 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.

[0064] 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 the indoor air and the refrigerant. An indoor fan is configured to draw indoor air into the indoor unit through the air inlet 111 and to discharge the indoor air, after heat exchange with the indoor heat exchanger, through the air outlet 112 of the indoor unit. The indoor fan provides power for the flow of indoor air.
