[0045] The cabinet 110 defines a receiving chamber 111 for receiving the air conditioner indoor unit 200 .

[0046] The cabinet door 120 is pivotally connected to the cabinet body 110 to open or cover the accommodating cavity 111 .

[0047] Among them, one end of the connecting rod 130 is rotatably connected to the cabinet door 120, and the other end of the connecting rod 130 is used to connect the front panel 220 of the air-conditioning indoor unit 200, so that the connecting rod 130 opens the front panel 220 when the cabinet door 120 is opened, and closes the front panel 220 when the cabinet door 120 is closed.

[0048] Those skilled in the art can understand that, by configuring the cabinet door 120 with a connecting rod 130 rotatably connected thereto, and connecting the end of the connecting rod 130 away from the cabinet door 120 to the front panel 220 of the air conditioner indoor unit 200, the connecting rod 130 opens the front panel 220 when the cabinet door 120 is opened, and closes the front panel 220 when the cabinet door 120 is closed. Therefore, the utility model realizes the opening and closing linkage between the cabinet door 120 and the front panel 220 of the air conditioner indoor unit 200, and the function is no longer single.

[0049] It should be noted that the cabinet 100 of the present invention is not limited to Figure 1 The cabinet 100 may be in any other feasible form. For example, the cabinet 100 may also include a Figure 1 The cabinet 100 is shown below and / or to the left and / or to the right.

Figure 1 As shown), it can also be any feasible storage device such as a cabinet, a wardrobe, a shelf, etc.

[0050] from Figure 1 It can be seen that in some embodiments of the present invention, the cabinet door 120 is pivotally connected to the cabinet body 110 through its top end, so that the cabinet door 120 can open the accommodating cavity 111 upwards and close the accommodating cavity 111 downwards.

[0051] In addition, in other embodiments of the present invention, those skilled in the art may also make the cabinet door 120 pivotally connected to the cabinet body 110 through its bottom end or one end in the left and right directions as needed.

[0052] like Figures 1 to 3 As shown, in some embodiments of the present invention, in the extension direction of the rotation axis of the cabinet door 120, all the connecting rods 130 are located between the two end surfaces of the cabinet door 120, so that all the connecting rods 130 are hidden by the cabinet door 120 after the cabinet door 120 is closed.

[0053] Those skilled in the art will appreciate that by arranging all the connecting rods 130 between the two end surfaces of the cabinet door 120 , all the connecting rods 130 can be hidden by the cabinet door 120 after the cabinet door 120 is closed, thereby ensuring the aesthetics of the cabinet 100 .

[0054] Furthermore, in some embodiments of the present invention, there are two connecting rods 130 .

[0055] In addition, in other embodiments of the present invention, those skilled in the art may also set the connecting rods 130 to any feasible number, such as one, three, or four, as required.

[0056] like Figure 3 As shown, in some embodiments of the present invention, a mounting groove 121 is provided on the cabinet door 120 so that the top end of the connecting rod 130 is embedded in the mounting groove 121, and a mounting hole 122 is provided on the side wall of the mounting groove 121 so that the rotating shaft 131 of the connecting rod 130 is embedded in the mounting hole 122, thereby realizing the connection between the connecting rod 130 and the cabinet door 120.

[0057] Furthermore, the mounting hole 122 passes through a side wall of the mounting groove 121 , so that the rotating shaft 131 of the connecting rod 130 passes through the mounting hole 122 from the outside of the cabinet door 120 into the mounting groove 121 and is plugged together with the connecting rod 130 .

[0058] like Figure 4 As shown, in some embodiments of the present invention, a rotating shaft 131 is respectively provided at both ends of the connecting rod 130 in the length direction, and the rotating shaft 131 can be removed from the connecting rod 130 to facilitate connecting the connecting rod 130 with the cabinet door 120 and the front panel 220.

[0059] Return to view Figure 1In some embodiments of the present invention, the air conditioner indoor unit 200 includes a casing 210 and a front panel 220 .

[0060] The front side of the housing 210 is provided with a return air port 211 and an air supply port 212 .

[0061] like Figure 1 and Figure 5 As shown, the front panel 220 is pivotally connected to the housing 210 to open or cover the return air outlet 211 . A connecting structure 221 is provided on the front panel 220 , and the connecting structure 221 is used to connect the connecting rod 130 .

[0062] Furthermore, the front panel 220 is rotatably connected to the housing 210 via its bottom end, and the connecting structure 221 is slidably connected to the connecting rod 130 .

[0063] like Figure 5 As shown, in some embodiments of the present invention, the connecting structure 221 is a sliding groove with an inverted T-shaped cross section. That is, the connecting structure 221 includes a narrow groove (not marked in the figure) with a narrower width and a wide groove (not marked in the figure). After the end of the connecting rod 130 away from the cabinet door 120 passes through the narrow groove, the rotating shaft 131 is embedded in the wide groove, thereby realizing the sliding connection between the connecting rod 130 and the connecting structure 221.

[0064] In order to realize the connection between the end of the connecting rod 130 away from the cabinet door 120 and the cabinet door 120, the technicians in this field may also, as needed, set a through hole on the side wall in the width direction of the slide groove, so that the rotating shaft 131 of the connecting rod 130 can pass through the through hole from the outside of the front panel 220 door into the wide groove and be plugged together with the connecting rod 130.

[0065] Alternatively, those skilled in the art may also, as required, set a clearance hole for avoiding the rotating shaft 131 at one end of the slide groove in the length direction, so that the rotating shaft 131 of the connecting rod 130 can be installed in the wide groove through the clearance hole. Furthermore, the front panel 220 may be provided with a component for shielding the clearance hole, and the component may be any feasible component.

[0066] Exemplarily, an internal thread structure is provided on the peripheral wall of the avoidance hole, and the component used to cover the avoidance hole is a screw or bolt matching the internal thread structure.

[0067] like Figure 6 As shown, in some other embodiments of the present invention, compared with some embodiments described above, the cabinet 100 may further include a driving device 140, and the driving device 140 is at least used to drive the cabinet door 120 to open.

[0068] It can be understood by those skilled in the art that by configuring the cabinet 100 with a driving device 140 and enabling the driving device 140 to at least drive the cabinet door 120 to open, the cabinet 100 of the utility model can be automatically opened by the driving device 140, freeing the user's hands and improving the user's experience.

[0069] Continue reading Figure 6 The driving device 140 includes an electric push rod 141 installed on the cabinet body 110 and a roller 142 installed at the telescopic end of the electric push rod 141, so that the driving device 140 abuts against the inner side surface of the cabinet door 120 through the roller 142.

[0070] Exemplarily, the telescopic end of the electric push rod 141 is set in a Y shape to form a space for arranging the roller 142. The roller 142 and the Y-shaped structure are rotatably fixed together through a pin or a rotating shaft 131.

[0071] Since it is a common technical means and common knowledge in the art to connect two interconnected parts together by rotation, it will not be described in detail here.

[0072] It is understood by those skilled in the art that, by making the driving device 140 include an electric push rod 141 installed on the cabinet body 110 and a roller 142 installed at the telescopic end of the electric push rod 141, the driving device 140 can be in rolling contact with the cabinet door 120 through the roller 142, thereby avoiding interference between the driving device 140 and the cabinet door 120. In addition, when the driving device 140 is powered off or damaged, the user can manually open the cabinet door 120, thereby ensuring that the air conditioner indoor unit 200 can work normally.

[0073] Those skilled in the art can also understand that, in other embodiments of the present invention, the cabinet door 120 is opened by the electric push rod 141 when the electric push rod 141 is extended, and can be automatically closed by gravity when the electric push rod 141 is shortened.

[0074] In addition, in other embodiments of the utility model, those skilled in the art may also set the driving device 140 to any other feasible device, such as a motor and a gear set, as needed. Exemplarily, the driving device 140 may include a motor, a housing of the motor is fixedly connected to the cabinet body 110, and a rotating shaft of the motor is fixedly connected to the cabinet door 120. When the motor rotates forward, the cabinet door 120 is driven to open, and when the motor rotates reversely, the cabinet door 120 is driven to close.

[0075] like Figure 7As shown, in other embodiments of the present invention, abutment structure 123 may be further provided on cabinet door 120. Moreover, both abutment structure 123 and roller 142 are magnetic attraction components (components that can be attracted by magnets), and at least one of abutment structure 123 and roller 142 is a magnet, so that abutment structure 123 and roller 142 are attracted together.

[0076] Those skilled in the art will appreciate that by providing an abutment structure 123 on the cabinet door 120, and providing both the abutment structure 123 and the roller 142 as magnetic components, and making at least one of the abutment structure 123 and the roller 142 a magnet, the abutment structure 123 and the roller 142 are attracted together, thereby avoiding the occurrence of a gap between the cabinet door 120 and the cabinet body 110 after the cabinet door 120 is closed.

[0077] Furthermore, the abutting structure 123 may be a metal sheet or a magnetic sheet adhered to the cabinet door 120 .

[0078] Those skilled in the art can understand that, in order to ensure that the driving device 140 and the cabinet door 120 can abut against each other, at least a portion of the projection of the driving device 140 on the plane where the cabinet door 120 is located falls within the area where the cabinet door 120 is located.

[0079] In addition, those skilled in the art may also, as required, set a sink groove on the cabinet body 110 and embed the driving device 140 into the sink groove, thereby ensuring that at least part of the projection of the driving device 140 on the plane where the cabinet door 120 is located falls within the area where the cabinet door 120 is located. At the same time, the overall aesthetics of the cabinet 100 is also ensured.

[0080] Refer to the following Figure 1 and Figure 8 The main structure of the air conditioner indoor unit 200 in the present invention is briefly described.

[0081] like Figure 1 and Figure 8 As shown, in the present invention, the air conditioner indoor unit 200 mainly includes a casing 210 , a front panel 220 , a heat exchanger 230 and a fan 240 .

[0082] Among them, the casing 210 is provided with a return air outlet 211 and an air supply outlet 212, so that the air-conditioning indoor unit 200 can return air from its front side and blow air toward its front side. Compared with the traditional wall-mounted air conditioner that returns air from the top side, the space for embedding the air-conditioning indoor unit 200 can be smaller, which not only improves the utilization rate of the space, but also makes the air-conditioning indoor unit 200 more perfectly integrated with the decoration environment.

[0083] The front panel 220 is rotatably connected to the housing 210 through its bottom end, and is used to open or cover the return air outlet 211 .

[0084] Further, the front panel 220 may be as follows Figure 1 As shown, a ventilation grille is provided, or it may be provided as Figure 5 Shown without ventilation grilles.

[0085] The heat exchanger 230 is used to cool or heat the air in the casing 210 .

[0086] Furthermore, when the air conditioner indoor unit 200 is cooling, the heat exchanger 230 is used as an evaporator to cool the air in the casing 210 ; when the air conditioner indoor unit 200 is heating, the heat exchanger 230 is used as a condenser to heat the air in the casing 210 .

[0087] The fan 240 is used to drive the air in the housing 210 to flow from the return air port 211 to the supply air port 212 .

[0088] Continue reading Figure 8 The air conditioning indoor unit 200 may further include a partition 250 .

[0089] The partition 250 is disposed in the housing 210 and extends from the return air port 211 to the heat exchanger 230, so that the air on the top side of the partition 250 flows to the portion of the heat exchanger 230 located on the top side of the fan 240. In other words, the partition 250 divides the housing 210 into two return air passages, one of which leads to the front of the heat exchanger 230 and the other leads to the rear of the heat exchanger 230.

[0090] Those skilled in the art will appreciate that by extending the partition 250 from the return air port 211 toward the heat exchanger 230, the air on the top side of the partition 250 flows toward the portion of the heat exchanger 230 located on the top side of the fan 240, and thus air flows through each portion of the heat exchanger 230, thereby ensuring the working efficiency of the heat exchanger 230. In addition, ice formation at the rear of the heat exchanger 230 due to insufficient air volume is avoided.

[0091] Furthermore, the partition 250 may be fixedly connected to the housing 210 or may be integrally formed therewith.

[0092] In example 1, the partition plate 250 is integrally formed with the front side plate of the housing 210 .

[0093] Example 2: A plug-in structure is provided on the partition 250, and a plug-in matching structure is provided on the front side plate of the housing 210. The partition 250 is plugged together with the front side plate of the housing 210 through the plug-in structure and the plug-in matching structure.

[0094] Example three: A vertical mounting plate is provided on the partition 250, a through hole is provided on the mounting plate, and a threaded hole is provided on the front side plate of the casing 210. The screws pass through the through hole and are tightened together with the threaded hole, thereby fixing the partition 250 to the front side plate of the casing 210.

[0095] Furthermore, although not shown in the figures, in some embodiments of the present invention, the air-conditioning indoor unit 200 may further include an air guide plate, which is disposed at the air supply outlet 212 to control the blowing direction of the air flow at the air supply outlet 212 .

[0096] Return to view Figure 1 The utility model also provides an air conditioning device 001, including the cabinet 100 described in any of the above embodiments and the air conditioning indoor unit 200 described in any of the above embodiments.

[0097] like Fig. 9 As shown, the air conditioning device 001 of the present invention may further include an air conditioning outdoor unit 300 .

[0098] When the air conditioning device 001 is cooling, the air conditioning outdoor unit 300 releases heat, and the air conditioning indoor unit 200 absorbs heat to cool the room.

[0099] When the air conditioning device 001 is heating, the air conditioning outdoor unit 300 absorbs heat, and the air conditioning indoor unit 200 releases heat to heat the room.

[0100] Those skilled in the art will appreciate that the air conditioning device 001 generally requires the use of its refrigeration system to perform cooling or heating.

[0101] 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.

[0102] Among them, the compressor and the pressure reducing member are generally provided in the air conditioner outdoor unit 300 .

[0103] Furthermore, a heat exchanger 230 is disposed in the air-conditioning outdoor unit 300 and the air-conditioning indoor unit 200 , respectively.

[0104] When the air conditioning device 001 is working, the refrigerant in the refrigeration system circulates along the following path: compressor→condenser→pressure reducing component→evaporator→compressor.

[0105] When the refrigerant flows through the compressor, it is compressed by the compressor into a high-temperature and high-pressure state (liquid or gas-liquid mixed state).

[0106] When the refrigerant flows through the condenser, the heat is dissipated through the condenser and the temperature is reduced to a low temperature and high pressure state (liquid or gas-liquid mixed state).

[0107] 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).

[0108] 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).

[0109] 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.

[0110] When the air conditioning device 001 is heating, the heat exchanger 230 in the air conditioning outdoor unit 300 is used as an evaporator, and the heat exchanger 230 in the air conditioning indoor unit 200 is used as a condenser.

[0111] When the air conditioning device 001 is cooling, the heat exchanger 230 in the air conditioning outdoor unit 300 is used as a condenser, and the heat exchanger 230 in the air conditioning indoor unit 200 is used as an evaporator.

[0112] 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.

[0113] 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.

[0114] 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.
