[0002] An air conditioner is a cooling and heating device, generally consisting of an indoor unit and an outdoor unit. An air conditioner generally uses the indoor unit for cooling and heating. Specifically, when the air conditioner is running in the cold winter, the indoor unit heats up the room, while when the air conditioner is running in the hot summer, the indoor unit cools down the room.

[0003] If a problem occurs during the use of the existing wall-mounted air conditioner indoor unit, it needs to be disassembled for maintenance, which increases the difficulty of maintaining the wall-mounted air conditioner indoor unit. Utility Model Content

[0004] One purpose of the utility model is to solve the problem that the existing wall-mounted air conditioner indoor unit is difficult to maintain.

[0005] A further object of the utility model is to overcome the problem of mixing of return air and supply air of an indoor unit of an air conditioner.

[0006] To achieve the above-mentioned object, the utility model provides a wall-mounted air conditioner indoor unit in a first aspect, comprising:

[0007] The housing comprises a rear housing and a front housing, wherein the front side of the rear housing is provided with an opening, and the front housing is mounted on the rear housing to cover the opening; and the front housing is provided with an air outlet;

[0008] a heat exchanger, arranged in the rear shell;

[0009] The fan is arranged in the rear shell.

[0010] Optionally, an air return port is also provided on the front shell.

[0011] Optionally, the air conditioner indoor unit further comprises a front panel mounted on the front shell, and the front panel is used for opening and shielding the return air outlet.

[0012] Optionally, the air conditioner indoor unit further comprises a driving device mounted on the front shell, wherein the driving device is configured to open and / or close the front panel.

[0013] Optionally, the driving device includes a driving motor, a driving connecting rod and a driven connecting rod, the driving motor is mounted on the rear shell or the front shell; the driving connecting rod is drivingly connected to the driving motor through one end thereof, the driving connecting rod is rotationally connected to one end of the driven connecting rod through the other end thereof, and the other end of the driven connecting rod is rotationally connected to the front panel.

[0014] Optionally, the return air outlet is arranged on the upper side of the air supply outlet; the front panel is rotatably connected to the front shell, and the rotation axis of the front panel is located on the bottom side of the front panel.

[0015] Optionally, projections of the heat exchanger and the fan on the plane where the opening is located fall within the contour of the opening to facilitate installation and maintenance of the heat exchanger and the fan.

[0016] Optionally, the electric control component of the air conditioner indoor unit is also arranged in the rear shell, and the projection of the electric control component on the plane where the opening is located falls within the contour of the opening to facilitate the installation and maintenance of the electric control component.

[0017] Optionally, the front shell is detachably connected to the rear shell; and / or, the air-conditioning indoor unit is an embedded air-conditioner.

[0018] The utility model provides an air conditioner in a second aspect, comprising an air conditioner outdoor unit and an air conditioner indoor unit as described in any one of the first aspects.

[0019] Based on the foregoing description, it can be understood by those skilled in the art that in the aforementioned technical solution of the utility model, by setting the casing as a rear casing with an opening on the front side and a front casing for shielding the opening, and arranging the heavier main components such as the heat exchanger and the fan in the rear casing, when the air-conditioning indoor unit fails, especially when the components arranged on the rear casing such as the heat exchanger and the fan fail, the front casing can be removed for maintenance. Therefore, when the air-conditioning indoor unit of the utility model fails, it does not need to be removed from the wall as a whole, and only the front casing needs to be removed for maintenance, which makes maintenance more convenient. In addition, since the rear casing and its internal components are blocked by the front casing and cannot be seen by the user, the process requirements of the rear casing can be reduced, thereby reducing the production cost of the air-conditioning indoor unit.

[0020] Furthermore, by arranging the return air outlet on the front shell, it is avoided to arrange the return air outlet on the rear shell, so that the air conditioner indoor unit of the utility model can be embedded in a smaller space. Unlike an ordinary wall-mounted air conditioner indoor unit, it is not necessary to reserve enough return air space for the return air outlet on the top thereof.

[0021] Furthermore, by providing a front panel for opening and covering the return air outlet on the front shell, the front panel can be opened when the air-conditioning indoor unit is in use to ensure normal cooling; when not in use, the front panel can be closed to prevent dust from entering the shell, while also ensuring the aesthetics of the air-conditioning indoor unit.

[0022] Furthermore, by configuring a driving device for opening and / or closing the front panel for the air-conditioning indoor unit, the air-conditioning indoor unit can automatically open and close the front panel, which is more intelligent and improves the user experience.

[0023] Furthermore, by setting the return air outlet on the upper side of the supply air outlet, and rotatably connecting the front panel to the front shell, and locating the rotating shaft of the front panel on the bottom side of the front panel, the front panel can be blocked between the return air outlet and the supply air outlet when opened, thereby effectively preventing the return air of the air conditioner indoor unit from being mixed with the cold air / hot air it delivers.

[0024] Furthermore, by making the projections of the heat exchanger, fan and electric control components on the plane where the opening is located fall within the outline of the opening, the installation and maintenance of the heat exchanger, fan and electric control components are facilitated. Specifically, when the heat exchanger, fan and electric control components need to be installed and maintained, only the front shell needs to be removed, so that maintenance personnel can perform maintenance, disassembly, installation and other operations on the heat exchanger, fan and electric control components.

[0025] Furthermore, by making the front shell and the rear shell detachably connected, it is convenient for maintenance personnel to disassemble the front shell.

[0026] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0039] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the wall-mounted air-conditioning indoor unit 100 includes a casing 110 , a heat exchanger 121 , an electronic control component 122 , an air guide plate 123 , a filter 124 , a fan 125 and a front panel 130 .

[0040] The housing 110 includes a rear housing 111 and a front housing 112. An opening 1111 is provided at the front side of the rear housing 111, and the front housing 112 is mounted on the rear housing 111 to cover the opening 1111.

[0041] Furthermore, the heat exchanger 121, the electronic control component 122, the air guide plate 123 and the fan 125 are all arranged on the rear shell 111, so that when these components fail, only the front shell 112 needs to be removed from the rear shell 111 for maintenance, and there is no need to remove the air conditioner indoor unit 100 from the wall as a whole, which makes maintenance more convenient.

[0042] In addition, in other embodiments of the present invention, those skilled in the art may also arrange only a part of the heat exchanger 121, the electric control component 122, the air guide plate 123 and the fan 125 on the rear housing 111 as needed. For example, only the heat exchanger 121, the electric control component 122 and the fan 125 are arranged on the rear housing 111.

[0043] The electric control component 122 is used to control the operation of the air-conditioning indoor unit 100 and may include a circuit board.

[0044] Furthermore, in some embodiments of the present invention, the front shell 112 may be detachably connected to the rear shell 111 to facilitate maintenance personnel to disassemble the front shell 112 .

[0045] The disassembly connection enables maintenance personnel to disassemble the front shell 112 from the rear shell 111 with just their hands without the aid of tools.

[0046] To this end, any feasible connection method such as snap connection, plug-in connection, magnetic connection, etc. can be used between the front shell 112 and the rear shell 111.

[0047] In addition, in other embodiments of the present invention, those skilled in the art may also configure the front shell 112 and the rear shell 111 to be connected in any other feasible manner, such as bolt / screw connection, as required.

[0048] like Figure 1 As shown, in some embodiments of the present invention, an air outlet 1121 is provided on the front shell 112 so that the air conditioner indoor unit 100 blows out cold air / hot air from the air outlet 1121 .

[0049] Continue reading Figure 1 In some embodiments of the present invention, a return air port 1122 is further provided on the front shell 112 so that the air conditioner indoor unit 100 returns air through the return air port 1122 .

[0050] Furthermore, since the air supply port 1121 and the air return port 1122 are both arranged on the front shell 112, the air conditioner indoor unit 100 of the present invention can be embedded in a smaller space, and it is not necessary to reserve enough air return space for the air return port 1122 at the top thereof like an ordinary wall-mounted air conditioner indoor unit 100.

[0051] It can be seen from this that the air-conditioning indoor unit 100 of the present invention can be a built-in air-conditioning.

[0052] like Figure 2 As shown, in some embodiments of the present invention, an air duct 1112 is defined on the rear shell 111 , an air inlet 11121 of the air duct 1112 is aligned with the return air outlet 1122 on the front shell 112 , and an air outlet 11122 of the air duct 1112 is aligned with the supply air outlet 1121 on the front shell 112 .

[0053] Continue reading Figure 2 In some embodiments of the present invention, the heat exchanger 121 and the fan 125 are both arranged in the air duct 1112 , and the heat exchanger 121 can be arranged upstream of the fan 125 .

[0054] When the air conditioner indoor unit 100 is cooling, the heat exchanger 121 is used as an evaporator to cool the air in the casing 110 ; when the air conditioner indoor unit 100 is heating, the heat exchanger 121 is used as a condenser to heat the air in the casing 110 .

[0055] The fan 125 is used to drive the air in the environment to enter the air duct 1112 through the return air port 1122 on the front housing 112 and the air inlet 11121 of the air duct 1112, and drive the air in the air duct 1112 to flow to the environment again through the air outlet 11122 of the air duct 1112 and the air supply port 1121 on the front housing 112. This reciprocating cycle is used to achieve cooling or heating of the environment by the air conditioner indoor unit 100.

[0056] from Figure 1 to Figure 2 It can be seen that the projections of the heat exchanger 121 , the electronic control component 122 , the air guide plate 123 and the fan 125 on the plane where the opening 1111 is located fall within the contour range of the opening 1111 , so that maintenance personnel can easily repair these components through the opening 1111 .

[0057] In addition, in other embodiments of the utility model, those skilled in the art may also, as needed, make the projections of only a portion of the heat exchanger 121, the electronic control component 122, the air guide plate 123 and the fan 125 on the plane where the opening 1111 is located fall within the contour range of the opening 1111.

[0058] The plane where the opening 1111 is located can be a plane in a strict sense, or a curved surface with a certain curvature.

[0059] The outline of the opening 1111 generally refers to the edge / side wall surrounding the opening 1111 .

[0060] It should be noted that, in the description of the present utility model, when the projection of a certain component on the plane where the opening 1111 is located falls within the contour range of the opening 1111, it may be that the projection of the entire component on the plane where the opening 1111 is located falls within the contour range of the opening 1111, or it may be that the projection of a part of the component on the plane where the opening 1111 is located falls within the contour range of the opening 1111.

[0061] Continue reading Figure 1 In some embodiments of the present invention, the filter 124 is installed at the return air outlet 1122 of the front shell 112, so that the user can remove the filter 124 for cleaning, replacement, etc.

[0062] Furthermore, the front shell 112 is provided with a grille (not marked in the figure) at the return air outlet 1122 thereof to prevent the filter screen 124 from being excessively deformed under the action of negative pressure.

[0063] Continue reading Figure 1 In some embodiments of the present invention, the front panel 130 is mounted on the front shell 112 to open and cover the return air outlet 1122 .

[0064] When the front panel 130 opens the return air port 1122, air in the environment can enter the housing 110 from the return air port 1122. When the front panel 130 shields the return air port 1122, dust can be prevented from entering the housing 110.

[0065] Further, the return air port 1122 is disposed on the upper side of the supply air port 1121. In addition, the front panel 130 is rotatably connected to the front housing 112, and the rotation axis of the front panel 130 is located at the bottom side of the front panel 130.

[0066] Those skilled in the art will appreciate that this arrangement of the return air vent 1122 and the front panel 130 enables the front panel 130 to be blocked between the return air vent 1122 and the supply air vent 1121 when opened, thereby effectively preventing the return air of the air-conditioning indoor unit 100 from being mixed with the cold air / hot air it delivers.

[0067] In addition, in other embodiments of the present invention, those skilled in the art may also dispose the rotation axis of the front panel 130 on the top side of the front panel 130 as needed.

[0068] Continue reading Figure 1 In some embodiments of the present invention, the air conditioner indoor unit 100 may further include a driving device 140 mounted on the front shell 112 , and the driving device 140 is configured to open and / or close the front panel 130 .

[0069] Furthermore, the driving device 140 includes a driving motor 141 , a driving connecting rod 142 and a driven connecting rod 143 .

[0070] The driving motor 141 is mounted on the rear housing 111 or the front housing 112. For example, the housing of the driving motor 141 is fixedly connected to the front housing 112.

[0071] The driving connecting rod 142 is drivingly connected to the driving motor 141 through one end thereof. The driving connecting rod 142 is rotationally connected to one end of the driven connecting rod 143 through the other end thereof, and the other end of the driven connecting rod 143 is rotationally connected to the front panel 130 .

[0072] Furthermore, one end of the driving connecting rod 142 can be directly coaxially fixedly connected to the rotating shaft of the driving motor 141, and one end of the driving connecting rod 142 can also be driven and connected to the rotating shaft of the driving motor 141 through a reducer.

[0073] In addition, those skilled in the art may also configure the driving device 140 to any other feasible structure as needed, such as a combination of an electric push rod, a motor and a gear pair.

[0074] Exemplarily, the driving device 140 includes a driving motor 141 fixedly connected to the rear housing 111, a housing of the driving motor 141 fixedly connected to the rear housing 111, and a gear coaxially fixedly connected to the rotating shaft of the driving motor 141. The front panel 130 is also provided with a gear at its rotating shaft, and the gear meshes with the gear on the driving motor 141. The driving motor 141 opens the front panel 130 when it rotates forward, and closes the front panel 130 when it rotates reversely.

[0075] In addition, in other embodiments of the utility model, those skilled in the art may also omit the provision of the driving device 140 as needed, and provide a structure on the front panel 130 for the user to manually open and close, so that the user can open and close the front panel 130 through objects such as a clothesline.

[0076] Refer to the following Figure 3 and Figure 4 The installation and maintenance of the air conditioner indoor unit 100 in the present invention will be briefly described.

[0077] like Figure 3 and Figure 4 As shown, when installing the air conditioner indoor unit 100 of the present invention, the front shell 112 and the rear shell 111 are first separated. Then the rear shell 111 is embedded in the cabinet 001 and fixed to the wall (such as Figure 3 Finally, the front shell 112 is installed on the rear shell 111 (as shown in FIG. Figure 4 shown).

[0078] When the air conditioner indoor unit 100 of the present invention needs to be repaired, the front shell 112 is first disassembled from the rear shell 111, so that the components inside the air conditioner indoor unit 100 are exposed (such as Figure 3 After the maintenance is completed, the front shell 112 is installed on the rear shell 111 (as shown in FIG. Figure 4 shown).

[0079] Based on the above description, it can be understood by those skilled in the art that, in some embodiments of the present invention, by setting the housing 110 as a rear housing 111 with an opening 1111 on the front side and a front housing 112 for shielding the opening 1111, and arranging the heavier main components such as the heat exchanger 121 and the fan 125 in the rear housing 111, when the air conditioner indoor unit 100 fails, especially when the components arranged on the rear housing 111 such as the heat exchanger 121 and the fan 125 fail, the front housing 112 can be disassembled for maintenance. Therefore, when the air conditioner indoor unit 100 of the present invention fails, it does not need to be disassembled from the wall as a whole, and only the front housing 112 needs to be disassembled for maintenance, which is more convenient for maintenance. In addition, since the rear housing 111 and its internal components are blocked by the front housing 112 and cannot be seen by the user, the process requirements of the rear housing 111 can be reduced, thereby reducing the production cost of the air conditioner indoor unit 100.

[0080] In addition, those skilled in the art may also, as required, set a filter opening for installing the filter 124 on the front panel 130 and omit the grille on the front shell 112. When the components in the air conditioner indoor unit 100 need to be repaired, the front panel 130 can be opened without removing the front shell 112, thereby further facilitating the maintenance of the air conditioner indoor unit 100 by maintenance personnel.

[0081] In addition, the utility model also provides an air conditioner 002.

[0082] like Figure 5 As shown, the air conditioner 002 includes the air conditioner indoor unit 100 and the air conditioner outdoor unit 200 described in any of the above embodiments.

[0083] When the air conditioner 002 is cooling, the air conditioner outdoor unit 200 releases heat, and the air conditioner indoor unit 100 absorbs heat to cool the room.

[0084] When the air conditioner 002 is heating, the air conditioner outdoor unit 200 absorbs heat, and the air conditioner indoor unit 100 releases heat to heat the room.

[0085] The air conditioner 002 generally needs to use its refrigeration system to complete cooling or heating.

[0086] The refrigeration system includes a compressor, a condenser, a pressure reducing component (an expansion valve or a capillary tube) and an evaporator which are connected end to end in sequence.

[0087] Among them, the compressor and the pressure reducing member are generally provided in the air conditioner outdoor unit 200 .

[0088] Furthermore, a heat exchanger 121 is disposed in the air-conditioning outdoor unit 200 and the air-conditioning indoor unit 100 , respectively.

[0089] When the air conditioner 002 is working, the refrigerant in the refrigeration system circulates along the following path: compressor→condenser→pressure reducing component→evaporator→compressor.

[0090] When the refrigerant flows through the compressor, it is compressed into a high-temperature and high-pressure state (liquid or gas-liquid mixed state).

[0091] When the refrigerant flows through the condenser, it dissipates heat through the condenser and cools down to a low temperature and high pressure state (liquid or gas-liquid mixed state).

[0092] When the refrigerant flows through the pressure reducing component, it is throttled and reduced in pressure to a low-temperature and low-pressure state (liquid state or gas-liquid mixed state).

[0093] When the refrigerant flows through the evaporator, it absorbs heat from the external environment through the evaporator and heats up to a high-temperature and low-pressure state (gaseous state).

[0094] Among them, the aforementioned states of the refrigerant in the compressor, condenser, pressure reducing component, and evaporator, that is, the high temperature, low temperature, high pressure, and low pressure of the refrigerant, are the states of the refrigerant after entering the corresponding components or flowing out of the corresponding components compared to the states before it flows into the corresponding components.

[0095] When the air conditioner 002 is heating, the heat exchanger 121 in the air conditioner outdoor unit 200 is used as an evaporator, and the heat exchanger 121 in the air conditioner indoor unit 100 is used as a condenser.

[0096] When the air conditioner 002 is cooling, the heat exchanger 121 in the air conditioner outdoor unit 200 is used as a condenser, and the heat exchanger 121 in the air conditioner indoor unit 100 is used as an evaporator.

[0097] It should be noted that the present invention only describes the main components of the refrigeration system and the general refrigerant flow path. In actual product applications, the refrigeration system may also have at least one series and / or parallel branch.

[0098] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0099] Finally, it should be noted that in the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
