Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and specifically provides an air conditioner indoor unit and an air conditioner. Background Art

[0002] An air conditioner is a cooling and heating device, generally including an indoor unit and an outdoor unit, which are connected by a connection pipe. 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, and when the air conditioner is running in the hot summer, the indoor unit cools down the room.

[0003] At present, the refrigerant in the air conditioner is mostly flammable gas. Since the air conditioner indoor unit is generally equipped with an electronic control component that controls the operation of the air conditioner, in order to prevent the refrigerant from leaking and coming into contact with the electronic control component and being ignited, the existing technology generally arranges the joint connecting the air conditioner indoor unit and the connecting pipe on the outside of the air conditioner indoor unit, so that the joint that is more prone to leakage and the electronic control component are in different spaces.

[0004] At present, the joint connecting the air conditioner indoor unit and the online pipe is generally arranged on the rear side of the air conditioner indoor unit. However, for the air conditioner indoor unit that needs to be embedded in the cabinet (especially the wall-mounted air conditioner indoor unit), if the air conditioner indoor unit is installed in the cabinet first, the joint will not be visible. If the air conditioner indoor unit is connected to the joint of the online pipe first, and then the air conditioner indoor unit is pushed into and installed in the cabinet, an extra length of the online pipe must be reserved, which is not only costly and occupies more space, but also the online pipe is at risk of being bent and flattened in the process. Therefore, the existing air conditioner indoor unit is not convenient to be embedded in the cabinet. Utility Model Content

[0005] One purpose of the utility model is to solve the problem that the existing air-conditioning indoor unit is inconvenient to be embedded in a cabinet.

[0006] To achieve the above-mentioned object, the utility model provides an 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; the rear housing defines a pipeline avoidance groove located at the rear side thereof, and the rear housing is provided with a mounting hole penetrating the front side wall of the pipeline avoidance groove;

[0008] A cover plate, sealingly connected to the housing to close the mounting hole;

[0009] a heat exchanger, arranged in the rear shell;

[0010] an indoor unit connector, connected to the heat exchanger fluid through a refrigerant pipe, the indoor unit connector being arranged in the pipeline avoidance groove and aligned with the mounting hole;

[0011] The electric control component is arranged in the rear shell.

[0012] Optionally, the mounting hole is located in the middle of the casing in the transverse direction of the casing.

[0013] Optionally, the electronic control component is located at one end of the casing in the transverse direction of the casing.

[0014] Optionally, the cover plate is connected to the casing by sliding, snapping or screwing.

[0015] Optionally, the projection of the mounting hole on the plane where the opening is located falls within the contour of the opening, so as to facilitate the connection between the indoor unit connector and the online pipe connector of the online pipe; and / or, the projection of the heat exchanger and the electronic control component on the plane where the opening is located falls within the contour of the opening, so as to facilitate the installation and maintenance of the heat exchanger and the electronic control component.

[0016] Optionally, the front shell is provided with a return air outlet and an air supply outlet.

[0017] 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.

[0018] 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.

[0019] Optionally, the air-conditioning indoor unit is a built-in air-conditioner; and / or, the air-conditioning indoor unit is a wall-mounted air-conditioner.

[0020] 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.

[0021] 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 two parts, namely, the rear casing and the front casing, the rear casing can be embedded in the cabinet and fixed to the wall before the front casing. By setting a pipeline avoidance groove on the rear side of the rear casing, setting a mounting hole that penetrates the front side wall of the pipeline avoidance groove on the rear casing, and arranging the indoor unit joint in the pipeline avoidance groove and aligning with the mounting hole, the installer can first fix the rear casing to the wall, and then connect the indoor unit joint to the online pipe joint of the online pipe through the mounting hole. Therefore, the air conditioner indoor unit of the utility model can be embedded in the cabinet relatively easily. The utility model also closes the mounting hole by configuring a cover plate that is sealed and connected to the casing, thereby preventing the air in the pipeline avoidance groove and the leaked refrigerant from entering the casing. Therefore, the installation of the air conditioner indoor unit of the utility model is more convenient.

[0022] Furthermore, by arranging the mounting hole in the middle of the casing in the transverse direction of the casing, interference between the indoor unit joint and the bracket or collision bolt fixing the indoor unit of the air conditioner to the wall is avoided.

[0023] Furthermore, by making the projection of the mounting hole on the plane where the opening is located fall within the contour range of the opening, it is convenient for the installer to connect the indoor unit joint with the online pipe joint of the online pipe.

[0024] Furthermore, by making the projections of the heat exchanger and the electric control component on the plane where the opening is located fall within the contour range of the opening, the installation and maintenance of the heat exchanger and the electric control component are facilitated.

[0025] Furthermore, by arranging the return air outlet and the air supply outlet on the front shell, the air conditioner indoor unit of the utility model can be embedded in a smaller space in the form of wall-mounted, without having to reserve enough return air space for the return air outlet on the top like an ordinary wall-mounted air conditioner indoor unit.

[0026] 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.

[0027] 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.

[0028] 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.

[0035] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0036] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] Furthermore, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", and "connect" should be understood in a broad sense.

A certain target object stores "cold" or "heat" in order to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0039] like Figures 1 to 3 As shown, in some embodiments of the present invention, the air conditioner indoor unit 100 includes a casing 110 , a heat exchanger 121 , an electric control component 122 , a cover plate 150 and an indoor unit connector 160 .

[0040] The housing 110 includes a rear housing 111 and a front housing 112. The front side of the rear housing 111 is provided with an opening 1111, and the front housing 112 is mounted on the rear housing 111 to cover the opening 1111. The rear housing 111 defines a pipeline avoidance groove 1112 at its rear side, and the rear housing 111 is provided with a mounting hole 1113 penetrating the front side wall of the pipeline avoidance groove 1112.

[0041] The heat exchanger 121 and the electric control assembly 122 are both arranged in the rear housing 111. When the air conditioner indoor unit 100 is cooling, the heat exchanger 121 is used as an evaporator to cool the air in the housing 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 housing 110.

[0042] The cover plate 150 is sealed and connected to the housing 110 to close the mounting hole 1113 .

[0043] The indoor unit connector 160 is fluidically connected to the heat exchanger 121 through the refrigerant pipe 1211 , and the indoor unit connector 160 is arranged in the pipeline avoidance groove 1112 and aligned with the installation hole 1113 .

[0044] Those skilled in the art can understand that, in some embodiments of the present invention, by providing a pipeline avoidance groove 1112 on the rear side of the rear shell 111, providing a mounting hole 1113 penetrating the front side wall of the pipeline avoidance groove 1112 on the rear shell 111, and arranging the indoor unit connector 160 in the pipeline avoidance groove 1112 and aligning with the mounting hole 1113, the installer can connect the indoor unit connector 160 with the online pipe connector 210 of the online pipe 200 through the mounting hole 1113. To this end, the present invention can first install the rear shell 111 and its internal components on the wall, and then connect the indoor unit connector 160 with the online pipe connector 210 of the online pipe 200, and then install the cover plate 150 on the rear shell 111, and finally install the front shell 112 on the rear shell 111.

[0045] Therefore, the air conditioner indoor unit 100 of the utility model is more convenient to be embedded in a cabinet. At the same time, by installing the cover plate 150 on the rear shell 111, the mounting hole 1113 can be closed by the cover plate 150, thereby preventing the air in the pipeline avoidance groove 1112 and the leaked refrigerant from entering the shell 110.

[0046] like Figure 2 As shown, in some embodiments of the present invention, the mounting hole 1113 is disposed in the middle of the casing 110 in the transverse direction of the casing 110 to prevent the indoor unit connector 160 from interfering with the bracket or collision bolt that fixes the air conditioner indoor unit 100 to the wall.

[0047] Furthermore, the electronic control component 122 is located at one end of the housing 110 in the lateral direction of the housing 110. For example, the electronic control component 122 may be as follows: Figure 1 As shown, it is arranged at the left end of the housing 110, and can also be arranged as shown in FIG. Figure 2 As shown, it is disposed at the right side end of the housing 110 .

[0048] In some embodiments of the present invention, the cover plate 150 may be any feasible component, such as a plastic sheet, a metal plate, a tape, etc.

[0049] Furthermore, the cover plate 150 and the housing 110 may be fixed together by any feasible connection method, such as a sliding connection, a snap connection, or a screw connection.

[0050] Exemplarily, a through hole is provided on the cover plate 150 , and a threaded hole corresponding to the through hole is provided on the rear shell 111 , so that the cover plate 150 can be fixed to the rear shell 111 by passing a bolt / screw through the through hole on the cover plate 150 and tightening it with the threaded hole.

[0051] like Figure 2 and Figure 4 As shown, the projection of the mounting hole 1113 on the plane where the opening 1111 is located falls within the contour of the opening 1111 to facilitate the connection between the indoor unit connector 160 and the online pipe connector 210 of the online pipe 200 .

[0052] It should be noted that, in some embodiments of the present invention, the plane where the opening 1111 is located can be a plane in the strict sense, or a curved surface with a certain curvature.

[0053] Further, the outline of the opening 1111 generally refers to the edge / side wall surrounding the opening 1111.

[0054] like Figures 1 to 4 As shown, in some embodiments of the present invention, the projections of the heat exchanger 121 and the electronic control component 122 on the plane where the opening 1111 is located fall within the contour range of the opening 1111 to facilitate the installation and maintenance of the heat exchanger 121 and the electronic control component 122.

[0055] 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.

[0056] like Figure 1 As shown, in some embodiments of the present invention, the front shell 112 is provided with a return air port 1122 and an air supply port 1121 .

[0057] 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 in the form of wall hanging, and it is not necessary to reserve enough air return space for the air return port 1122 at the top thereof like the ordinary air conditioner indoor unit 100.

[0058] It can be seen that the air conditioner indoor unit 100 of the present invention can be an embedded air conditioner and a wall-mounted air conditioner. That is, the air conditioner indoor unit 100 of the present invention can be an air conditioner indoor unit 100 embedded in the cabinet 001 and mounted on the wall.

[0059] Furthermore, in some embodiments of the present invention, the filter 124 of the air conditioner indoor unit 100 can be 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.

[0060] 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.

[0061] Continue reading Figure 1 In some embodiments of the present invention, the air conditioner indoor unit 100 may further include a front panel 130 mounted on the front shell 112 to open and shield the return air outlet 1122 through the front panel 130 .

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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 .

[0067] Furthermore, the driving device 140 includes a driving motor 141 , a driving connecting rod 142 and a driven connecting rod 143 .

[0068] 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.

[0069] 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 .

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] like Figure 3 As shown, in some embodiments of the present invention, an air duct 1114 is defined on the rear shell 111 , an air inlet 11141 of the air duct 1114 is aligned with the return air outlet 1122 on the front shell 112 , and an air outlet 11142 of the air duct 1114 is aligned with the supply air outlet 1121 on the front shell 112 .

[0075] Continue reading Figure 3 In some embodiments of the present invention, the heat exchanger 121 and the fan 125 of the air-conditioning indoor unit 100 are both arranged in the air duct 1114 , and the heat exchanger 121 can be arranged upstream of the fan 125 .

[0076] 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 .

[0077] The fan 125 is used to drive the air in the environment to enter the air duct 1114 through the return air port 1122 on the front housing 112 and the air inlet 11141 of the air duct 1114, and drive the air in the air duct 1114 to flow to the environment again through the air outlet 11142 of the air duct 1114 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.

[0078] like Figures 1 to 3 As shown, in some embodiments of the present invention, the air guide plate 123 of the air conditioner indoor unit 100 is also installed on the rear shell 111 and is located at the air outlet 11142 of the air duct 1114 and / or the air supply port 1121 of the front shell 112.

[0079] Furthermore, the projection of the air guide plate 123 on the plane where the opening 1111 is located falls within the contour range of the opening 1111 , so as to facilitate the maintenance of the air guide plate 123 .

[0080] Refer to the following Figure 1 , Figure 2 and Figure 3 , to briefly describe the installation process of the air conditioner indoor unit 100 in some embodiments of the present invention.

[0081] For the convenience of explanation, hereinafter, the rear shell 111 and the components installed therein are collectively referred to as the rear shell part, and the front shell 112 and the components installed on the front shell 112 are collectively referred to as the front shell part.

[0082] First, the online pipe joint 210 of the online pipe 200 is arranged on the wall, and then the mounting hole 1113 on the rear shell 111 is aligned with the online pipe joint 210, and the rear shell part is installed and fixed to the wall. Then the installer uses a wrench or other tool to connect the indoor unit joint 160 and the online pipe joint 210 together, and then fixes the cover plate 150 to the rear shell 111, thereby sealing the mounting hole 1113. Finally, the front shell part is installed on the rear shell 111.

[0083] When the air conditioner indoor unit 100 fails, maintenance personnel can remove the front shell 112 from the rear shell 111 so that the components in the rear shell part are exposed by the opening 1111 on the rear shell 111, thereby facilitating inspection and maintenance by maintenance personnel.

[0084] Furthermore, the front shell 112 may be detachably connected to the rear shell 111 to facilitate maintenance personnel to disassemble the front shell 112 .

[0085] 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.

[0086] 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.

[0087] Based on the foregoing description, those skilled in the art will appreciate that the present invention not only facilitates the installation personnel to connect the indoor unit connector 160 with the online pipe connector 210, so that the air-conditioning indoor unit 100 of the present invention can be more easily embedded in the cabinet; it also facilitates the maintenance personnel to inspect and repair the internal components of the air-conditioning indoor unit 100.

[0088] In addition, the utility model also provides an air conditioner 001.

[0089] like Figure 5 As shown, the air conditioner 001 includes an air conditioner indoor unit 100, a connection pipe 200 and an air conditioner outdoor unit 300 described in any of the above embodiments. The air conditioner indoor unit 100 and the air conditioner outdoor unit 300 are respectively connected to the connection pipe 200 through a joint, so that the refrigerant circulates between the air conditioner indoor unit 100 and the air conditioner outdoor unit 300.

[0090] When the air conditioner 001 is cooling, the air conditioner outdoor unit 300 releases heat, and the air conditioner indoor unit 100 absorbs heat to cool the room.

[0091] When the air conditioner 001 is heating, the air conditioner outdoor unit 300 absorbs heat, and the air conditioner indoor unit 100 releases heat to heat the room.

[0092] The air conditioner 001 generally needs to use its refrigeration system to complete cooling or heating.

[0093] 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.

[0094] Among them, the compressor and the pressure reducing member are generally provided in the air conditioner outdoor unit 300 .

[0095] Furthermore, a heat exchanger 121 is disposed in each of the air-conditioning outdoor unit 300 and the air-conditioning indoor unit 100 .

[0096] When the air conditioner 001 is working, the refrigerant in the refrigeration system circulates along the following path: compressor→condenser→pressure reducing component→evaporator→compressor.

[0097] When the refrigerant flows through the compressor, it is compressed into a high-temperature and high-pressure state (liquid or gas-liquid mixed state).

[0098] 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).

[0099] 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).

[0100] 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).

[0101] 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.

[0102] When the air conditioner 001 is heating, the heat exchanger 121 in the air conditioner outdoor unit 300 is used as an evaporator, and the heat exchanger 121 in the air conditioner indoor unit 100 is used as a condenser.

[0103] When the air conditioner 001 is cooling, the heat exchanger 121 in the air conditioner outdoor unit 300 is used as a condenser, and the heat exchanger 121 in the air conditioner indoor unit 100 is used as an evaporator.

[0104] 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.

[0105] 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.
