[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.

[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 1-13 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, and a drive assembly 3. 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 processed air back into the room, thus effectively forming 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, the drive assembly 3 is disposed inside the outer cover 11 and is connected to the front panel 12 in a transmission manner. 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 3 can provide the front panel 12 with the power 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.

[0026] Furthermore, the wall-mounted air conditioner indoor unit 100 also includes a transmission rod 4, which is connected to the drive assembly 3. The drive assembly 3 can drive the transmission rod 4 to rotate. Moreover, the outer casing 11 is provided with a support portion 113 and a support base 114, with a mounting hole 2 formed between the support base 114 and the support portion 113. The transmission rod 4 is rotatably inserted through the mounting hole 2. Thus, the support base 114 and the support portion 113 provide support for the transmission rod 4. When the transmission rod 4 rotates, since it is located within the mounting hole 2 formed between the support base 114 and the support portion 113, deformation and vibration of the transmission rod 4 during rotation can be avoided, thereby making the transmission rod 4 more stable during rotation.

[0027] The support portion 113 is provided with a first snap-fit ​​portion 1131 and a second snap-fit ​​portion 1132 on both sides of the mounting hole 2 in the front-back direction, and the support base 114 is provided with a third snap-fit ​​portion 1141 and a fourth snap-fit ​​portion 1142 on both sides of the mounting hole 2 in the front-back direction. The first snap-fit ​​portion 1131 and the third snap-fit ​​portion 1141 are snap-fitted together, and the second snap-fit ​​portion 1132 and the fourth snap-fit ​​portion 1142 are snap-fitted together.

[0028] Furthermore, the first snap-fit ​​portion 1131 and the second snap-fit ​​portion 1132 are provided on the left and right sides of the mounting hole 2, and the third snap-fit ​​portion 1141 and the fourth snap-fit ​​portion 1142 can also be provided on the left and right sides of the mounting hole 2. This forms a snap-fit ​​structure on both sides and a "double-point constraint," thereby preventing the first snap-fit ​​portion 1131 and the third snap-fit ​​portion 1141 from being misaligned or skewed during the snap-fit ​​engagement. It also avoids stress concentration or functional failure caused by unilateral fixing of the support portion 113 and the support base 114. Moreover, it also prevents the second snap-fit ​​portion 1132 and the fourth snap-fit ​​portion 1142 from being misaligned or skewed during the snap-fit ​​engagement.

[0029] Furthermore, the third locking portion 1141 is adapted to be rotatable relative to the first locking portion 1131 when the second locking portion 1132 and the fourth locking portion 1142 are not engaged. Specifically, during installation, the support base 114 can first be engaged with the first locking portion 1131 of the support portion 113, but the third locking portion 1141 can rotate relative to the first locking portion 1131. This rotation allows the fourth locking portion 1142 of the support base 114 and the second locking portion 1132 of the support portion 113 to engage. This provides the advantage of effortless installation and also makes the engagement between the support base 114 and the support portion 113 more stable.

[0030] Furthermore, the bottom of the support base 114 can be rotated by the third snap-fit ​​part 1141, which allows the fourth snap-fit ​​part 1142 of the support base 114 and the second snap-fit ​​part 1132 of the support part 113 to snap into each other. This reduces the number of buckles that fix the support base 114 to the outer cover 11, saving time and making installation and disassembly easier.

[0031] Moreover, when the transmission rod 4 needs to be removed or repaired, it can be unlocked by simply rotating the support base 114 in the opposite direction. Only the second locking part 1132 and the fourth locking part 1142 need to be changed from the locking state to the disengaged state. There is no need to disassemble other parts, which can greatly shorten the repair time.

[0032] Therefore, while ensuring that the support base 114 can be installed stably, the wall-mounted air conditioner indoor unit 100 can not only reduce the number of fasteners for fixing the support base 114 and the outer cover 11, but also facilitate the installation and disassembly of the support base 114 and the support part 113.

[0033] According to some embodiments of this utility model, such as Figure 4 As shown, one of the first locking part 1131 and the third locking part 1141 is a hook with an opening, and the other of the first locking part 1131 and the third locking part 1141 is a rotating shaft, and the hook engages with the rotating shaft.

[0034] In other words, when the first locking part 1131 is set as a hook, the third locking part 1141 can be set as a pivot. When the first locking part 1131 is set as a pivot, the third locking part 1141 can be set as a hook. In this way, the hook and the pivot engage to restrict the pivot from being located in the opening of the hook, thereby facilitating the pivot to rotate in the opening of the hook.

[0035] According to some embodiments of this utility model, such as Figure 4 and Figure 6 As shown, the third snap-fit ​​portion 1141 is respectively disposed on both sides of the width direction of one end of the support base 114, and the third snap-fit ​​portion 1141 and the first snap-fit ​​portion 1131 are snap-fitted together in a one-to-one correspondence.

[0036] The third snap-fit ​​portion 1141 can be symmetrically arranged on both sides of the bottom end of the support base 114 in the width direction. Correspondingly, the first snap-fit ​​portion 1131 can be symmetrically arranged on both sides of the bottom end of the support portion 113 in the width direction. In this way, the third snap-fit ​​portion 1141 and the first snap-fit ​​portion 1131 are snap-fitted together in a one-to-one correspondence. This not only makes the connection between the bottom end of the support base 114 and the bottom end of the support portion 113 more stable, but also avoids the use of screws.

[0037] According to some embodiments of this utility model, such as Figures 4-8As shown, a connecting plate 1133 is connected between the first snap-fit ​​parts 1131, one end of the support base 114 abuts against the connecting plate 1133, and a limiting rib 5 is provided at one end of the support base 114. The limiting rib 5 and the first snap-fit ​​parts 1131 are limited and matched along the width direction of the support base 114.

[0038] The first snap-fit ​​part 1131 can be configured as a snap hook, and the connecting plate 1133 is connected between the two first snap-fit ​​parts 1131. In this way, the connecting plate 1133 can support the two first snap-fit ​​parts 1131 and improve the strength of the two first snap-fit ​​parts 1131, thereby preventing the first snap-fit ​​parts 1131 from deforming.

[0039] Furthermore, one end of the support base 114 abuts against the connecting plate 1133. For example, the bottom end of the support base 114 abuts against the connecting plate 1133. In this way, the connecting plate 1133 can also provide support for the bottom end of the support base 114, thereby facilitating the installation of the support base 114.

[0040] Furthermore, a limiting rib 5 is provided at one end of the support base 114. The limiting rib 5 and the first locking part 1131 are limited and engaged along the width direction of the support base 114. For example, the limiting rib 5 is provided at the bottom end of the support base 114. The limiting rib 5 is in the shape of a mountain. Correspondingly, the bottom end of the support part 113 is provided with the first locking part 1131. When the support base 114 tends to move in the left and right direction, the limiting rib 5 is provided at the bottom end of the support base 114. The limiting rib 5 and the first locking part 1131 are limited and engaged, thereby preventing the support base 114 from moving in the left and right direction of the outer cover 11.

[0041] According to some embodiments of this utility model, such as Figure 4 As shown, one of the second snap-fit ​​portion 1132 and the fourth snap-fit ​​portion 1142 is a snap-fit, and the other of the second snap-fit ​​portion 1132 and the fourth snap-fit ​​portion 1142 is a snap-fit ​​hole. The snap-fit ​​and the snap-fit ​​hole engage in a snap-fit ​​relationship.

[0042] In other words, when the second latching part 1132 is configured as a latch, the fourth latching part 1142 is configured as a latching hole, and when the second latching part 1132 is configured as a latching hole, the fourth latching part 1142 is configured as a latch. For example, the front end of the support base 114 can be configured as a latching hole, and correspondingly, a latch can be provided on the support part 113. The latch extends into the latching hole, thereby achieving a fixed connection between the front end of the support base 114 and the support part 113.

[0043] According to some embodiments of this utility model, such as Figures 4-8As shown, the second snap-fit ​​portion 1132 is respectively disposed on both sides of the support portion 113 in the width direction, and the support base 114 is respectively disposed on both sides of the support base 114 in the width direction. The limiting plate 1143 is provided with the fourth snap-fit ​​portion 1142, and the support portion 113 is disposed between the limiting plates 1143 on both sides to limit and cooperate with the limiting plates 1143.

[0044] The second latching portions 1132 are respectively disposed on both sides of the support portion 113 in the width direction, so that the support portion 113 can provide an installation position for the second latching portions 1132, thereby facilitating the installation of the second latching portions 1132. Limiting plates 1143 are respectively disposed on both sides of the support base 114 in the width direction, and the limiting plates 1143 are provided with fourth latching portions 1142, so that the limiting plates 1143 can provide a position for the fourth latching portions 1142.

[0045] Furthermore, the support portion 113 is disposed between the limiting plates 1143 on both sides, so that the limiting plates 1143 on both sides can be interference-fitted with the support portion 113, thereby making the connection and cooperation between the support portion 113 and the limiting plates 1143 more stable and firm.

[0046] According to some embodiments of this utility model, such as Figures 4-7 As shown, the support base 114 includes a base body 1144, a connecting part 7, and a mounting part 8. The support part 113 is provided with a first half-hole 61, and the base body 1144 is provided with a second half-hole 62. The first half-hole 61 and the second half-hole 62 are arranged opposite to each other to form a mounting hole 2. In this way, when the transmission rod 4 is installed, the first half-hole 61 can be moved away from the second half-hole 62, which can avoid obstructing the transmission rod 4 and facilitate the installation of the transmission rod 4.

[0047] Furthermore, the connecting part 7 is connected to the base 1144, and the mounting part 8 is connected to the connecting part 7. The mounting part 8 is provided with a third snap-fit ​​part 1141, which provides a mounting position for the third snap-fit ​​part 1141, thus facilitating its installation. The support part 113 is provided with a fourth snap-fit ​​part 1142, which also provides a mounting position for the fourth snap-fit ​​part 1142, facilitating its installation.

[0048] According to some embodiments of this utility model, such as Figure 7 and Figure 10 As shown, the fourth snap-fit ​​portion 1142 is provided at one end of the length direction of the mounting portion 8, and the other end of the length direction of the mounting portion 8 is provided with a limiting groove 81. The support portion 113 is provided with a limiting protrusion 63, and the limiting protrusion 63 and the limiting groove 81 are mutually limiting and engaged.

[0049] Thus, the limiting groove 81 is recessed downwards, and correspondingly, the limiting protrusion 63 is protruded and extends into the limiting groove 81, which can prevent the mounting part 8 from separating from the support part 113.

[0050] According to some embodiments of this utility model, such as Figures 2-12 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 111 and the indoor heat exchanger, thereby filtering the air entering from the air inlet 111.

[0051] In this way, the filter can filter the dust entering from the air inlet 111, thereby effectively filtering the dust and other particulate matter drawn in from the air inlet 111, which can directly improve the cleanliness of the air blown into the room, thus helping to improve indoor air quality.

[0052] The support portion 113 has a mounting groove 9, and the support base 114 is disposed in the mounting groove 9. The mounting groove 9 can provide an installation position for the support base 114, which can make reasonable use of the space of the mounting groove 9 and make it more compact.

[0053] The support portion 113 has a first guide structure 64, which facilitates the guidance of the filter screen during installation. The mounting portion 8 has a second guide structure 80, which also guides the filter screen during installation. The second guide structure 80 is located between the first guide structures 64 on both sides of the mounting groove 9, and the first guide structures 64 and the second guide structure 80 respectively cooperate with the filter screen for guidance.

[0054] In this way, the second guide structure 80 and the first guide structure 64 can work together to provide guidance. The first guide structure 64 and the second guide structure 80 are respectively matched 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 64 and the second guide structure 80, 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.

[0055] According to some embodiments of this utility model, such as Figures 1-13 As shown, there are at least two drive components 3, and the transmission rod 4 is connected between two adjacent drive components 3. Alternatively, the drive component 3 may include a drive member 31 and at least two transmission mechanisms 32. The drive member 31 is connected to the transmission rod 4, and the at least two transmission mechanisms 32 are disposed on the transmission rod 4 and connected to the front panel 12.

[0056] The number of drive components 3 can be set to two. The transmission rod 4 is connected between two adjacent drive components 3. The drive components 3 can be set to two, and the transmission rod 4 is set between the two drive components 3. The transmission rod 4 extends in the left and right direction. In this way, one drive component 3 can transmit power to the other drive component 3 through the transmission rod 4. The other drive component 3 can rotate under the drive of one drive component 3 through the transmission rod 4. In this way, the two drive components 3 can share a drive, which can simplify the structure and reduce the number of parts.

[0057] Furthermore, at least two transmission mechanisms 32 are disposed on the transmission rod 4. When the transmission rod 4 rotates, it can transmit power to the transmission mechanisms 32. Since at least two transmission mechanisms 32 are connected to the front panel 12, the transmission mechanisms 32 can drive the front panel 12 to move up or down, thereby realizing the opening and closing of the front panel 12.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.
