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, split-type air conditioners commonly include cabinet air conditioners 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 circulating 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 cantilever structure mounted on the drive assembly and transmission rod protrudes from the end face of the drive assembly. During assembly, this cantilever structure is prone to colliding with the casing, affecting the operation of the drive assembly. 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 1-13 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 housing 1, an indoor heat exchanger, and a drive assembly 3. The housing 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 setting of the air inlet 111 can facilitate 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 providing supplemental air and increasing the air intake volume to meet the current air intake demand. It also exposes the entire air outlet 112, thereby increasing the air supply range and preventing 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. The drive assembly 3 can provide power to the front panel 12, so that the front panel 12 can selectively open and close the front side of the outer cover 11.

[0026] The drive assembly 3 includes: a mounting housing 31, a drive component 5, a reduction mechanism 6, and a transmission mechanism 7. The drive component 5 is disposed in the mounting housing 31, which provides a mounting position for the drive component 5, thereby facilitating its installation. The reduction mechanism 6 is disposed in the mounting housing 31, which provides a mounting position for the reduction mechanism 6 and also serves to protect the reduction mechanism 6.

[0027] Furthermore, the reduction mechanism 6 is connected to the drive component 5, and the transmission mechanism 7 is connected to both the reduction mechanism 6 and the front panel 12. Thus, the drive component 5 can transmit power to the reduction mechanism 6, which, after reduction, can output the required speed to the transmission mechanism 7. Since the transmission mechanism 7 is located between the reduction mechanism 6 and the front panel 12, the drive component 5 can drive the reduction mechanism 6 to operate, the reduction mechanism 6 can transmit power to the transmission mechanism 7, and the transmission mechanism 7 can transmit power to the front panel 12. This allows the front panel 12 to rise and fall.

[0028] The mounting housing 31 has a through hole 311, and the reduction mechanism 6 has a transmission end 61, allowing the transmission end 61 to extend out of the mounting housing 31 through the through hole 311. The wall-mounted air conditioner indoor unit 100 also includes a transmission rod 8, which is connected to the transmission end 61, allowing the transmission end 61 to transmit power to the transmission rod 8, thus enabling the transmission rod 8 to rotate. A protective structure 4 is provided on the outside of the through hole 311 of the mounting housing 31. The protective structure 4 is located on the outer periphery of the transmission end 61, protecting the outer periphery of the transmission end 61. Furthermore, the protective structure 4 is spaced apart from the transmission end 61, thus preventing collision between the outer cover 11 and the transmission end 61 during the installation of the drive assembly 3.

[0029] Therefore, the protective structure 4 in the indoor unit 100 of the wall-mounted air conditioner is located on the outer periphery of the transmission end 61. When the drive assembly 3 is installed, it can prevent the transmission end 61 from colliding with the outer cover 11, thereby protecting the transmission end 61.

[0030] According to some embodiments of this utility model, such as Figure 4 As shown, the protective structure 4 is constructed as a closed-loop structure surrounding the transmission end 61.

[0031] Thus, the protective structure 4 can surround the transmission end 61, preventing the transmission end 61 from contacting other parts, thereby avoiding interference between the transmission end 61 and other parts.

[0032] Moreover, the protective structure 4 is set as a closed-loop structure to form a surrounding physical barrier, which can effectively prevent foreign objects (such as tools) from accidentally entering the transmission area and avoid damage to the equipment. It can also protect the transmission end 61 from collisions and squeezing, thereby extending its service life.

[0033] According to some embodiments of this utility model, such as Figure 4 As shown, the cross-section of the outer circumference of the transmission end 61 along the central axis of the transmission rod 8 is circular. Thus, by setting the cross-section of the transmission end 61 to be circular, the installation angle of the transmission end 61 does not need to be considered during installation, thereby improving the installation efficiency of the transmission end 61.

[0034] Furthermore, the cross-section of the outer periphery of the protective structure 4 along the central axis of the transmission rod 8 is a non-parallelogram. For example, the protective structure 4 can be set as a quadrilateral, so that the top, bottom and sides of the transmission end 61 can be surrounded, achieving 360° all-round protection, thereby extending the service life of the transmission end 61.

[0035] According to some embodiments of this utility model, such as Figure 7 As shown, the protective structure 4 includes a top protective plate 41, a bottom protective plate 42, an outer protective plate 43, and an inner protective plate 44. The top protective plate 41 is located at the top of the transmission end 61, thus shielding the top of the transmission end 61 and preventing it from colliding with the outer cover 11. The bottom protective plate 42 is located at the bottom of the transmission end 61, thus shielding the bottom of the transmission end 61 and preventing it from colliding with the outer cover 11.

[0036] Furthermore, the outer protective plate 43 is connected between the top protective plate 41 and the bottom protective plate 42, and the outer protective plate 43 is located outside the transmission end 61. In this way, the outer protective plate 43 can shield the outer side of the transmission end 61, thereby preventing the outer side of the transmission end 61 from colliding with the outer cover 11. The inner protective plate 44 is connected between the top protective plate 41 and the bottom protective plate 42, and the inner protective plate 44 is located inside the transmission end 61. The inner protective plate 44 can shield the inner side of the transmission end 61, thereby preventing the inner side of the transmission end 61 from colliding with the outer cover 11.

[0037] Furthermore, the inner protective plate 44 and the outer protective plate 43 are not arranged in parallel. This increases the space between the inner protective plate 44 and the outer protective plate 43, thereby preventing interference between the transmission end 61 and the inner protective plate 44 and the outer protective plate 43.

[0038] According to some embodiments of this utility model, such as Figure 6 As shown, the outer cover 11 is provided with a support portion 113, which can support the outer cover 11 and thus prevent the outer cover 11 from deforming. The support portion 113 is provided with a mounting groove 1131, and the groove wall of the mounting groove 1131 is provided with a limiting plate 1132, which can provide an installation position for the limiting plate 1132.

[0039] Furthermore, at least one of the top protective plate 41, bottom protective plate 42, and outer protective plate 43 is engaged with the limiting plate 1132 for positioning. That is, the top protective plate 41 can be engaged with the limiting plate 1132 for positioning, thus preventing movement of the top protective plate 41 and also preventing drop impact. The bottom protective plate 42 can be engaged with the limiting plate 1132 for positioning, thus preventing movement of the bottom protective plate 42 and also preventing drop impact. The outer protective plate 43 can be engaged with the limiting plate 1132 for positioning, thus preventing movement of the outer protective plate 43 and also preventing drop impact. The outer protective plate 43 is positioned relative to the inner protective plate 44 closer to the front panel 12.

[0040] According to some embodiments of this utility model, the wall-mounted air conditioner indoor unit 100 further includes a filter screen, which is disposed inside the outer cover 11 and located between the air inlet 111 and the indoor heat exchanger to filter the air entering from the air inlet 111. In this way, the filter screen can filter dust entering from the air inlet 111, thereby effectively filtering 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.

[0041] Among them, such as Figure 12 As shown, the mounting shell 31 is provided with a first guide structure 312, which is located on the inner side of the inner protective plate 44, i.e. the side away from the front panel 12. In this way, when the filter is installed, the filter on the inner side of the inner protective plate 44 can overlap the first guide structure 312. The first guide structure 312 can guide the installation of the filter, thereby achieving accurate installation of the filter.

[0042] Furthermore, the first guide structure 312 and the inner protective plate 44 are spaced apart, which can make reasonable use of space. A guide groove 313 is formed between the first guide structure 312 and the inner protective plate 44, providing a certain installation path for the filter screen. The edge of the filter screen passes through the guide groove 313. When the user installs or resets the filter screen, there is no need for deliberate alignment; simply push the filter screen along the guide groove 313, and it will be automatically guided to the correct position. This ensures that the filter screen is completely and accurately installed in the designed position, thus avoiding gaps caused by misalignment.

[0043] According to some embodiments of this utility model, such as Figure 12As shown, the support part 113 is provided with a second guide structure 1133, which is located in the length extension direction of the first guide structure 312. In this way, the second guide structure 1133 and the first guide structure 312 can work together to provide guidance. The first guide structure 312 and the second guide structure 1133 cooperate with the filter screen guide to make the installation trajectory of the filter screen more accurate. The first guide structure 312 and the second guide structure 1133 can also provide support for the filter screen.

[0044] According to some embodiments of this utility model, such as Figures 5-12 As shown, the mounting housing 31 includes a main housing 314 and a cover plate 315. One side of the main housing 314 is open, which facilitates the installation of the cover plate 315. The reduction mechanism 6 is disposed inside the main housing 314, and the cover plate 315 is disposed on one side of the main housing 314. In this way, the cover plate 315 can cover one side of the main housing 314 and can also be easily disassembled, thereby facilitating its maintenance.

[0045] Furthermore, the reduction mechanism 6 is housed within the main housing 314, which provides an installation position for the reduction mechanism 6. The through hole 311 and protective structure 4 are located on the other side of the main housing 314, thus preventing interference between the through hole 311, protective structure 4, and the reduction mechanism 6. A cover plate 315 is located on one side of the main housing 314, allowing the reduction mechanism 6 to be opened for maintenance and easy installation and disassembly when damaged. Additionally, the drive component 5 is located on the side of the cover plate 315 facing away from the main housing 314, allowing for efficient use of space and preventing interference between the drive component 5 and other parts.

[0046] According to some embodiments of this utility model, such as Figures 5-13 As shown, the reduction mechanism 6 includes multiple gears 62, which are disposed within a mounting housing 31, providing mounting positions for the gears 62. The gears 62 drive sequentially, with the first gear 62 connected to the drive member 5, thus enabling the drive member 5 to drive the first gear 62 to rotate.

[0047] Furthermore, the transmission end 61 is located on one side of the tail gear 62, so that the tail gear 62 can transmit power to the transmission end 61, and the transmission end 61 can drive the transmission rod 8 to rotate.

[0048] Furthermore, the transmission mechanism 7 includes a rocker arm 71 and a panel connector 72. A gear 62 located at the tail end is disposed at one end of the rocker arm 71. Thus, the gear 62 at the tail end can also transmit power to the rocker arm 71 at the same time, thereby facilitating the rotation of the rocker arm 71.

[0049] Furthermore, a panel connector 72 is disposed on the front panel 12, with one end of the panel connector 72 connected to the other end of the rocker arm 71, and the other end of the panel connector 72 slidably disposed on the outer cover 11. Specifically, the gear 62 located at the tail end can transmit power to the rocker arm 71, which rotates under drive, causing the panel connector 72 to move. Since the other end of the panel connector 72 is slidably disposed on the outer cover 11, the front panel 12 on the front side of the outer cover 11 can be pulled up or down.

[0050] According to some embodiments of this utility model, such as Figure 3 As shown, there are at least two drive components 3, and the transmission rod 8 is connected between the transmission ends 61 of two adjacent reduction mechanisms 6, or the drive component 3 includes at least two transmission mechanisms 7, and the at least two transmission mechanisms 7 are disposed on the transmission rod 8.

[0051] The number of drive components 3 can be set to two. The transmission rod 8 is connected between two adjacent drive components 3. The drive components 3 can be set to two, and the transmission rod 8 is set between the two drive components 3. The transmission rod 8 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 8. The other drive component 3 can rotate under the drive of one drive component 3 through the transmission rod 8. In this way, the two drive components 3 can share a drive, which can simplify the structure and reduce the number of parts.

[0052] Furthermore, at least two transmission mechanisms 7 are disposed on the transmission rod 8. When the transmission rod 8 rotates, it can transmit power to the transmission mechanisms 7. Since at least two transmission mechanisms 7 are connected to the front panel 12, the transmission mechanisms 7 can drive the front panel 12 to move up or down, thereby realizing the opening and closing of the front panel 12.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] It should be noted that the directions described in the text are based on the direction the user faces when facing the indoor unit of the air conditioner. Specifically, the side of the indoor unit facing the user when in use is defined as the front side, and the opposite side is defined as the rear side. The left and right sides are distinguished by the direction the user faces when facing the indoor unit.
