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 design with a movable front panel, which uses a drive assembly to open the front of the casing to supplement air intake, effectively increasing the air volume. However, the drive assembly is powered by a gear mechanism equipped with a stepper motor. The drive assembly is installed on the casing first, followed by the gear mechanism. Before the gear mechanism is installed, the components within the drive assembly can rotate freely without constraint, causing inconvenience during 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 1-14 Description of a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present utility model.

[0022] Reference Figures 1-5As 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 2. 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, it 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, it opens the front side of the outer cover 11, allowing 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 requirements. 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 2 is disposed inside the outer cover 11 and is connected to the front panel 12 in a transmission manner. The drive assembly 2 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 2 includes a drive component 21, a reduction mechanism 22, and a transmission mechanism 33. The reduction mechanism 22 is housed inside the outer cover 11, which provides a mounting position for the reduction mechanism 22 and also protects it. The reduction mechanism 22 is connected to the drive component 21, so the drive component 21 drives the reduction mechanism 22 to move, and the reduction mechanism 22 can output the required rotational speed.

[0027] Furthermore, the transmission mechanism 33 is connected to the reduction mechanism 22 and the front panel 12 respectively, so that the power output by the reduction mechanism 22 can be transmitted to the front panel 12 through the transmission mechanism 33, thereby facilitating the raising and lowering of the front panel 12.

[0028] The transmission mechanism 33 includes a first mounting shell 331, a rocker arm 332, a front panel connector 333, and an initial position limiting member 4. The first mounting shell 331 is disposed on the outer cover 11. One end of the rocker arm 332 is connected to the reduction mechanism 22, so that the reduction mechanism 22 can transmit power to one end of the rocker arm 332, thereby facilitating the rotation of the rocker arm 332. The front panel connector 333 is disposed on the front panel 12, and one end of the front panel connector 333 is connected to the other end of the rocker arm 332. Thus, the rotation of the rocker arm 332 can drive the front panel connector 333 to move. Since the front panel connector 333 is connected to the front panel 12, it is convenient for the front panel connector 333 to drive the front panel 12 to rise and fall.

[0029] Furthermore, the initial position limiting member 4 is disposed between the first mounting shell 331 and the rocker arm 332. In this way, one end of the initial position limiting member 4 can abut against the first mounting shell 331, and the other end of the initial position limiting member 4 can abut against the rocker arm 332. Before the deceleration mechanism 22 is installed inside the outer cover 11, the initial position limiting member 4 is installed in this way to keep the initial position of the rocker arm 332 unchanged, thereby limiting the initial position of the rocker arm 332 and facilitating the installation of the deceleration mechanism 22.

[0030] Therefore, the initial position limiting member 4 in the wall-mounted air conditioner indoor unit 100 is set between the first mounting shell 331 and the rocker arm 332. Before the deceleration mechanism 22 is installed, the initial position of the rocker arm 332 can be kept unchanged, thereby limiting the initial position of the rocker arm 332 and facilitating the installation of the deceleration mechanism 22.

[0031] According to some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the initial position limiting member 4 is constructed as an elastic limiting member.

[0032] The elastic limiting member can be compressed or deformed. After installation, the elastic limiting member is positioned between the first mounting shell 331 and the rocker arm 332. One end of the elastic limiting member is tightly fitted with the first mounting shell 331 through compression and deformation, while the other end of the elastic limiting member is tightly fitted with the rocker arm 332 through compression and deformation. In this way, the elastic limiting member can support the first mounting shell 331 and the rocker arm 332, thereby further ensuring that the initial position of the rocker arm 332 remains unchanged.

[0033] Moreover, since the elastic limiting member can undergo elastic deformation, it can compensate for the dimensional tolerance between the first mounting shell 331 and the rocker arm 332 through compression or deformation, making it easier to keep the initial position of the rocker arm 332 unchanged, thus facilitating the installation of the elastic limiting member.

[0034] According to some embodiments of this utility model, such as Figure 7 and Figure 8 As shown, the initial position limiting member 4 includes: a main body 41, a first limiting part 42, and a second limiting part 43. The first limiting part 42 is disposed on the main body 41, so that the first limiting part 42 and the main body 41 can be integrated into one unit, thereby reducing the number of parts and avoiding the need for the first limiting part 42 to be installed on the main body 41.

[0035] Furthermore, the first limiting part 42 is disposed on the first mounting shell 331, so that the first limiting part 42 can be tightly fitted with the first mounting shell 331 under force. The second limiting part 43 is disposed on the main body 41, so that the second limiting part 43 can be integrated with the main body 41, which can further reduce the number of parts and also avoid installation. Moreover, the second limiting part 43 is disposed at a distance from the first limiting part 42, so that the first limiting part 42 and the second limiting part 43 can avoid interference between them, and also provide a certain installation space for the initial position limiting member 4, thereby facilitating the installation of the initial position limiting member 4.

[0036] Furthermore, at least one of the second limiting part 43 and the first limiting part 42 is elastically deformable relative to the main body 41. That is, the second limiting part 43 can elastically deform relative to the main body 41, or the first limiting part 42 can elastically deform relative to the main body 41, or both the first limiting part 42 and the second limiting part 43 can elastically deform. In this way, the initial position limiting member 4 can be prevented from loosening, thereby ensuring the initial position of the rocker arm 332 and increasing the stability of the connection between the initial position limiting member 4 and the rocker arm 332.

[0037] Furthermore, the elastic deformation of the first limiting part 42 and the second limiting part 43 can make the first limiting part 42 fit tightly against the first mounting shell 331, and the second limiting part 43 is provided on the rocker arm 332, so that the second limiting part 43 can fit tightly against the rocker arm 332, thereby preventing the initial position limiting member 4 from loosening or dislodging due to vibration.

[0038] According to some embodiments of this utility model, such as Figures 7-10 As shown, a first mating plate 5 is provided inside the first mounting shell 331, and a first limiting part 42 abuts against the first mating plate 5.

[0039] The first mounting shell 331 contains a first mating plate 5, which provides a mounting position for the first mating plate 5, facilitating its installation. Furthermore, the first mating plate 5 possesses sufficient structural strength to prevent deformation or damage when the first limiting part 42 abuts against it. This prevents the elastic force generated by compression from the first limiting part 42 from pressing against the first mating plate 5, and also avoids displacement of the first limiting part 42, thus ensuring more accurate positioning of the first limiting part 42.

[0040] According to some embodiments of this utility model, such as Figures 7-10 As shown, the first limiting part 42 and the second limiting part 43 are respectively disposed at both ends of the axial direction of the main body 41. The first mounting shell 331 is provided with a limiting plate 6 connected to the first mating plate 5. A limiting groove 7 is formed between the limiting plate 6 and the rocker arm 332. The first limiting part 42 passes through the limiting groove 7.

[0041] The first limiting part 42 and the second limiting part 43 are respectively disposed at both ends of the axial direction of the main body 41. This can limit both ends of the axial direction of the main body 41, prevent the first limiting part 42 and the second limiting part 43 from moving in any direction of the axial direction of the main body 41, and improve the connection reliability. This can prevent the first limiting part 42 and the second limiting part 43 from axial movement or falling off due to vibration or external force.

[0042] Furthermore, the first mounting shell 331 is provided with a limiting plate 6 connected to the first mating plate 5. The limiting plate 6 protrudes towards the initial position limiting member 4, so that the first limiting part 42 can be limited and engaged with the limiting plate 6, thereby preventing the first limiting part 42 from separating from the limiting plate 6.

[0043] Furthermore, a limiting groove 7 is formed between the limiting plate 6 and the rocker arm 332, and a part of the first limiting part 42 passes through the limiting groove 7. Thus, the limiting groove 7 can accommodate a part of the first limiting part 42, and the limiting groove 7 can restrict the first limiting part 42, thereby preventing the first limiting part 42 from sliding out of the limiting groove 7.

[0044] According to some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the rocker arm 332 is provided with a limiting boss 8. When the front panel 12 is opened to the limit position, the limiting boss 8 is located on the side of the first mating plate 5 away from the first limiting part 42, and the limiting boss 8 is in stop engagement with the first mating plate 5.

[0045] The rocker arm 332 is provided with a limiting boss 8. The limiting boss 8 not only facilitates the stopping engagement between the limiting boss 8 and the first mating plate 5, but also increases the contact area between the limiting boss 8 and the first mating plate 5. Moreover, the mechanical stopping between the limiting boss 8 and the first mating plate 5 can limit the maximum opening angle of the rocker arm 332, and also prevent the front panel 12 from interfering with the outer cover 11 due to an excessively large opening angle of the rocker arm 332.

[0046] Moreover, when the rocker arm 332 drives the front panel 12 to the highest position, the limiting boss 8 and the first mating plate 5 stop each other, which can prevent the front panel 12 from falling off due to gravity, and can also prevent the front panel 12 from falling back due to vibration or external force, thus playing a role in protecting the front panel 12.

[0047] Furthermore, the limiting boss 8 is located on the side of the first mating plate 5 away from the first limiting part 42. This reduces the distance between the limiting boss 8 and the first mating plate 5, thereby facilitating the connection and mating between the limiting boss 8 and the first mating plate 5.

[0048] According to some embodiments of this utility model, such as Figures 7-10 As shown, the rocker arm 332 includes: a shaft 3321, a connecting plate 3322, an arm 3323, and a second mating plate 3324. The main body 41 is sleeved on the shaft 3321, the shaft 3321 is connected to the reduction mechanism 22, the connecting plate 3322 is connected to one side of the shaft 3321, the arm 3323 is connected to the connecting plate 3322, and the arm 3323 is connected to the front panel connector 333. The second mating plate 3324 is disposed on the connecting plate 3322, and the second mating plate 3324 is located on one side of the shaft 3321. The second limiting part 43 abuts against the second mating plate 3324.

[0049] The main body 41 is fitted onto the shaft 3321, which facilitates the connection between the initial position limiting member 4 and the rocker arm 332. The shaft 3321 is connected to the reduction mechanism 22, which can transmit the power of the reduction mechanism 22 to the shaft 3321.

[0050] Furthermore, the connecting plate 3322 is connected to one side of the shaft 3321. The connecting plate 3322 provides an installation position for the shaft 3321 and also improves the connection strength between the connecting plate 3322 and the shaft 3321. Since the arm 3323 is connected to the front panel connector 333, the movement of the arm 3323 can drive the front panel connector 333 to move. The second mating plate 3324 is disposed on the connecting plate 3322, and the second mating plate 3324 and the connecting plate 3322 are integrated, thereby improving the strength of the second mating plate 3324. Moreover, the second mating plate 3324 is located on one side of the shaft 3321, and the second limiting part 43 abuts against the second mating plate 3324, thereby restricting the movement of the second mating plate 3324.

[0051] According to some embodiments of this utility model, such as Figures 6-10 As shown, the second mating plate 3324 is disposed on the edge of the connecting plate 3322, and the second mating plate 3324 is connected to the arm body 3323.

[0052] The second mating plate 3324 is disposed at the edge of the connecting plate 3322. The second mating plate 3324 and the connecting plate 3322 are connected as a whole, which not only improves the strength of the second mating plate 3324, but also prevents the second mating plate 3324 from deforming under stress. Moreover, the fact that the second mating plate 3324 is disposed at the edge of the connecting plate 3322 reduces the distance between the second mating plate 3324 and the second limiting part 43, and also facilitates the abutting engagement between the second limiting part 43 and the second mating plate 3324, thereby preventing the second limiting part 43 from moving.

[0053] Furthermore, the second mating plate 3324 is connected to the arm body 3323, and the second mating plate 3324 and the arm body 3323 can become a whole. When the second limiting part 43 abuts against the second mating plate 3324, the second limiting part 43 can restrict the movement of the second mating plate 3324. Since the second mating plate 3324 and the arm body 3323 can become a whole, the second limiting part 43 can restrict the movement of the arm body 3323.

[0054] According to some embodiments of this utility model, such as Figures 1-12 As shown, the first mounting shell 331 is provided with an opening 9 for the arm body 3323 to extend out. A baffle 10 is provided on the upper edge of the opening 9. When the front panel 12 is opened to the limit position, the second mating plate 3324 and the baffle 10 stop and cooperate.

[0055] The first mounting shell 331 is provided with an opening 9 for the arm body 3323 to extend out. This prevents the first mounting shell 331 from obstructing the arm body 3323 and also facilitates the arm body 3323 to extend out of the opening 9 and connect with the front panel connector 333. In addition, a baffle 10 is provided on the upper edge of the opening 9. When the front panel 12 is opened to its limit position, the baffle 10 can prevent the connecting plate 3322 from moving, thereby limiting the rise of the front panel 12 and preventing the front panel 12 from colliding with the outer cover 11.

[0056] According to some embodiments of this utility model, the elastic limiting member is constructed as a torsion spring.

[0057] The torsion spring is sleeved on the shaft 3321. The torsion spring has the advantage of withstanding tens of thousands of torsional cycles without failure, and it maintains stable elasticity even under long-term high-frequency operation. Due to the elasticity of the torsion spring, the first limiting part 42 can extend into the limiting groove 7 and fit tightly against it, restricting movement of the first limiting part 42 and thus ensuring its position. Furthermore, using a torsion spring as the elastic limiting element offers advantages such as low cost and simple structure.

[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.

[0066] 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.
