[0043] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the air conditioner indoor unit 100 includes a casing 110 and at least one wind range extender 120 .

[0044] The housing 110 has an air return port 111 and an air supply port 112 .

[0045] The wind range extender 120 is arranged at the air supply port 112 to increase the velocity of the air flow passing therethrough, so as to increase the air supply distance of the air conditioner indoor unit 100 .

[0046] Those skilled in the art can understand that by arranging at least one wind range extender 120 at the air supply outlet 112 of the air-conditioning indoor unit 100 to increase the flow rate of the air flow passing therethrough, the air supply distance of the air-conditioning indoor unit 100 of the utility model is increased, thereby improving the user experience.

[0047] like Figure 2 As shown, in some embodiments of the present invention, the wind range extender 120 includes an air guide barrel 121 , an impeller 122 disposed in the air guide barrel 121 , and a range extender motor 123 for driving the impeller 122 to rotate.

[0048] Those skilled in the art can understand that, by making the wind range extender device 120 include an air guide barrel 121, an impeller 122 arranged in the air guide barrel 121 and a range extender motor 123 that drives the impeller 122 to rotate, the range extender motor 123 can drive the impeller 122 to blow air out of the air-conditioning indoor unit 100 through the air guide barrel 121, so that the air is uniformly accelerated in the air guide barrel 121, thereby ensuring the speed of the air when it is blown out of the air guide barrel 121.

[0049] Continue reading Figure 2 In the flow direction of the airflow, the range extender motor 123 is disposed upstream of the impeller 122. Alternatively, those skilled in the art may also dispose the range extender motor 123 downstream of the impeller 122 in the flow direction of the airflow as required.

[0050] Continue reading Figure 2 In some embodiments of the present invention, the air guide barrel 121 is installed on the casing 110 , and the range-extending motor 123 is fixedly connected to the air guide barrel 121 and drivingly connected to the impeller 122 .

[0051] Furthermore, a fixed bracket (not marked in the figure) is provided between the range-extending motor 123 and the air guide barrel 121 , the outer end of the fixed bracket is fixedly connected to the air guide barrel 121 , and the inner end of the fixed bracket is fixedly connected to the shell of the range-extending motor 123 .

[0052] Those skilled in the art can understand that the provision of the fixing bracket can not only realize the fixed connection between the range-extending motor 123 and the air guide barrel 121 , but also ensure that the airflow flows through the air guide barrel 121 .

[0053] Furthermore, a fixed bracket (not marked in the figure) is also provided between the impeller 122 and the air guide barrel 121 , and the outer end of the fixed bracket is fixedly connected to the air guide barrel 121 , so that the inner end of the fixed bracket is connected to the impeller 122 .

[0054] In addition, on the premise of ensuring that the impeller 122 can drive air to flow through the air guide barrel 121 when it rotates, technical personnel in this field may also, as needed, arrange the range extender motor 123 and the impeller 122 on the outside of the air guide barrel 121, and connect the range extender motor 123 and / or the impeller 122 to the casing 110.

[0055] like Figure 2 As shown, in some embodiments of the present invention, the air guide barrel 121 is rotatably connected to the housing 110 so that the air guide barrel 121 can swing left and right relative to the housing 110.

[0056] Specifically, a mounting shaft 1211 is provided on the bottom side of the air guide barrel 121, and a mounting hole (not marked in the figure) compatible with the mounting shaft 1211 is provided on the casing 110. The mounting shaft 1211 is embedded in the mounting hole so that the air guide barrel 121 can be rotatably mounted on the casing 110.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the air-conditioning indoor unit 100 further includes a driving device 130 for driving the air guide barrel 121 to rotate left and right.

[0058] from Figure 1 It can be seen that the air conditioner indoor unit 100 includes multiple wind range extenders 120, and the multiple wind range extenders 120 are spaced apart in sequence along the length direction of the air supply port 112, so that more air can be blown out through the wind range extender 120 while ensuring that the wind range extender 120 can swing left and right.

[0059] like Figure 3 As shown, in some embodiments of the present utility model, the air guide barrel 121 of each wind range extender 120 is respectively drivingly connected to the driving device 130 .

[0060] Specifically, the driving device 130 includes a driving motor 131 and a driving component 132 drivingly connected to the driving motor 131 . The driving component 132 is rotationally connected to each air guide barrel 121 , so that the driving motor 131 forces all wind range extenders 120 to rotate synchronously through the driving component 132 .

[0061] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a driving shaft 1212 is provided on the air guide barrel 121 , and a strip hole 1321 is provided on the driving member 132 , and the driving shaft 1212 is embedded in the strip hole 1321 to prevent interference between the driving shaft 1212 and the driving member 132 .

[0062] Furthermore, although not shown in the figures, in some embodiments of the present invention, the driving member 132 is slidably connected to the casing 110, and the driving member 132 can slide along the length direction of the air outlet 112 to ensure that the moving driving member 132 can drive the air guide barrel 121 to swing.

[0063] like Figure 3 As shown, in some embodiments of the present invention, the driving device 130 further includes a gear 133 coaxially fixed to the driving motor 131 and a rack 134 fixedly connected to or integrally formed with the driving member 132 , and the gear 133 meshes with the rack 134 .

[0064] The driving motor 131 may be installed inside the housing 110 and fixedly connected to the housing 110 .

[0065] Those skilled in the art can understand that by providing the driving device 130 with a gear 133 coaxially fixed with the driving motor 131 and a rack 134 fixedly connected to or integrally formed with the driving member 132, and by meshing the gear 133 with the rack 134, the air-conditioning indoor unit 100 can change the orientation of the wind range extender 120 by the forward and reverse rotation of the driving motor 131, thereby changing the blowing direction of the air-conditioning indoor unit 100.

[0066] It is understood by those skilled in the art that, since the wind range extender 120 can swing left and right, the wind range extender 120 can increase the air supply angle of the air conditioner indoor unit 100 while achieving long-distance air supply. Because the existing air conditioner indoor unit 100 guides the air left and right through the air guide plate, when the angle of rotation of the air guide plate is large, it will form a great resistance to the airflow, so the turning angle of the air guide plate cannot be too large. The wind range extender 120 of the utility model can ensure its air supply volume and air supply distance regardless of the angle of rotation, so the wind range extender 120 of the utility model can turn to the left and right at a larger angle than the existing air guide plate.

[0067] Return to view Figure 1 and Figure 2 In some embodiments of the present invention, the front side and the top side of the housing 110 are both provided with return air ports 111, so that the air conditioner indoor unit 100 can return air from its front side and top side and blow air toward its front side. Compared with the traditional wall-mounted air conditioner that only returns air from the top side, the return air area of ​​the air conditioner indoor unit 100 of the present invention is larger and the return air resistance is smaller.

[0068] It can be understood by those skilled in the art that, since the return air outlet 111 of the present invention is set in the above-mentioned form, the air-conditioning indoor unit 100 of the present invention can be embedded in a smaller space when being installed, which not only improves the utilization rate of the space, but also makes the air-conditioning indoor unit 100 more perfectly integrated with the decoration environment.

[0069] like Figure 2 As shown, the air conditioner indoor unit 100 further includes a heat exchanger 140 and a fan 150 .

[0070] The heat exchanger 140 is used to cool or heat the air in the housing 110 .

[0071] Furthermore, when the air conditioner indoor unit 100 is cooling, the heat exchanger 140 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 140 is used as a condenser to heat the air in the casing 110 .

[0072] The fan 150 is used to drive the air in the housing 110 to flow from the return air port 111 to the supply air port 112 .

[0073] Continue reading Figure 2 The air conditioning indoor unit 100 may further include a partition 160 .

[0074] The partition 160 is disposed in the housing 110 and extends from the return air port 111 to the heat exchanger 140, so that the air on the top side of the partition 160 flows to the portion of the heat exchanger 140 located on the top side of the fan 150. In other words, the partition 160 divides the housing 110 into two return air passages, one of which leads to the front of the heat exchanger 140 and the other leads to the rear of the heat exchanger 140.

[0075] Those skilled in the art will appreciate that by extending the partition 160 from the return air port 111 toward the heat exchanger 140, the air on the top side of the partition 160 flows toward the portion of the heat exchanger 140 located on the top side of the fan 150, and thus all parts of the heat exchanger 140 are flowed through by air, thereby ensuring the working efficiency of the heat exchanger 140. In addition, ice formation at the rear of the heat exchanger 140 due to insufficient air volume is avoided.

[0076] Furthermore, the partition 160 may be fixedly connected to the housing 110 or may be integrally formed therewith.

[0077] In example 1, the partition plate 160 is integrally formed with the front side plate of the housing 110 .

[0078] Example 2: A plug-in structure is provided on the partition 160, and a plug-in matching structure is provided on the front side plate of the housing 110. The partition 160 is plugged together with the front side plate of the housing 110 through the plug-in structure and the plug-in matching structure.

[0079] Example three: A vertical mounting plate is provided on the partition 160, a through hole is provided on the mounting plate, and a threaded hole is provided on the front side plate of the casing 110. The screws pass through the through hole and are tightened together with the threaded hole, thereby fixing the partition 160 to the front side plate of the casing 110.

[0080] like Figure 4 As shown, in some embodiments of the present invention, the air conditioner indoor unit 100 may further include a front panel 170 rotatably connected to the casing 110 , and the front panel 170 is used to open and cover the return air outlet 111 .

[0081] Furthermore, the front panel 170 is rotatably connected to the housing 110 through its bottom end, so that when the front panel 170 is opened, the front panel 170 separates the return air port 111 from the supply air port 112, thereby preventing the air blown out from the supply air port 112 from directly flowing to the return air port 111. At the same time, the front panel 170 can also serve to decorate the air conditioner indoor unit 100.

[0082] like Figure 4 As shown, the utility model also provides a cabinet 200 .

[0083] Continue reading Figure 4 In some embodiments of the present invention, the cabinet 200 includes a cabinet body 210 , a cabinet door 220 and at least one connecting rod 230 .

[0084] The cabinet 210 defines a receiving chamber 211 for receiving the air conditioner indoor unit 100 .

[0085] The cabinet door 220 is pivotally connected to the cabinet body 210 to open or cover the accommodating cavity 211 .

[0086] Among them, one end of the connecting rod 230 is rotatably connected to the cabinet door 220, and the other end of the connecting rod 230 is used to connect the front panel 170 of the air-conditioning indoor unit 100, so that the connecting rod 230 opens the front panel 170 when the cabinet door 220 is opened, and closes the front panel 170 when the cabinet door 220 is closed.

[0087] Those skilled in the art can understand that, by configuring the cabinet door 220 with a connecting rod 230 rotatably connected thereto, and connecting the end of the connecting rod 230 away from the cabinet door 220 to the front panel 170 of the air-conditioning indoor unit 100, the connecting rod 230 opens the front panel 170 when the cabinet door 220 is opened, and closes the front panel 170 when the cabinet door 220 is closed. Therefore, the utility model realizes the opening and closing linkage between the cabinet door 220 and the front panel 170 of the air-conditioning indoor unit 100.

[0088] It should be noted that the cabinet 200 of the present invention is not limited to Figure 4 The form shown in FIG. 1 may be any other feasible form. For example, the cabinet 200 may also include a Figure 4 The cabinet 200 is shown below and / or to the left and / or to the right. The cabinet 200 of the present invention may be a storage device (such as a storage device) used only to place the indoor unit 100 of the air conditioner. Figure 4 As shown), it can also be any feasible storage device such as a cabinet, a wardrobe, a shelf, etc.

[0089] from Figure 4It can be seen that in some embodiments of the present invention, the cabinet door 220 is pivotally connected to the cabinet body 210 through its top end, so that the cabinet door 220 can open the accommodating cavity 211 upward and close the accommodating cavity 211 downward.

[0090] In addition, in other embodiments of the present invention, those skilled in the art may also make the cabinet door 220 pivotally connected to the cabinet body 210 through its bottom end or one end in the left and right directions as needed.

[0091] like Figures 4 to 6 As shown, in some embodiments of the present invention, in the extension direction of the rotation axis of the cabinet door 220, all the connecting rods 230 are located between the two end surfaces of the cabinet door 220, so that all the connecting rods 230 are hidden by the cabinet door 220 after the cabinet door 220 is closed.

[0092] It can be understood by those skilled in the art that by arranging all the connecting rods 230 between the two end surfaces of the cabinet door 220 , all the connecting rods 230 can be hidden by the cabinet door 220 after the cabinet door 220 is closed, thereby ensuring the aesthetics of the cabinet 200 .

[0093] Furthermore, in some embodiments of the present invention, there are two connecting rods 230 .

[0094] In addition, in other embodiments of the present invention, those skilled in the art may also set the connecting rods 230 to any feasible number, such as one, three, or four, as required.

[0095] like Figure 8 As shown, in some embodiments of the present invention, a mounting groove 221 is provided on the cabinet door 220 so that the top end of the connecting rod 230 is embedded in the mounting groove 221, and a fixing hole 222 is provided on the side wall of the mounting groove 221 so that the rotating shaft 231 of the connecting rod 230 is embedded in the fixing hole 222, thereby realizing the connection between the connecting rod 230 and the cabinet door 220.

[0096] Furthermore, the fixing hole 222 passes through a side wall of the installation groove 221 , so that the rotating shaft 231 of the connecting rod 230 passes through the fixing hole 222 from the outside of the cabinet door 220 into the installation groove 221 and is plugged together with the connecting rod 230 .

[0097] like Figure 8 As shown, in some embodiments of the present invention, a rotating shaft 231 is respectively provided at both ends of the connecting rod 230 in the length direction, and the rotating shaft 231 can be removed from the connecting rod 230 to facilitate connecting the connecting rod 230 with the cabinet door 220 and the front panel 170.

[0098] like Figure 8As shown, in some embodiments of the present invention, a connecting structure 171 may be further provided on the front panel 170 , and the connecting structure 171 is used to connect the connecting rod 230 .

[0099] Furthermore, the connection structure 171 is located on the inner side of the front panel 170 , and the connection structure 171 is slidably connected to the connecting rod 230 .

[0100] like Figure 8 As shown, in some embodiments of the present invention, the connecting structure 171 is a sliding groove with an inverted T-shaped cross section. That is, the connecting structure 171 includes a narrow groove ( Figure 8 Not marked in ) and a wider slot ( Figure 8 After the end of the connecting rod 230 away from the cabinet door 220 passes through the narrow groove, the rotating shaft 231 is embedded in the wide groove, thereby realizing the sliding connection between the connecting rod 230 and the connecting structure 171.

[0101] In order to realize the connection between the end of the connecting rod 230 away from the cabinet door 220 and the cabinet door 220, 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 231 of the connecting rod 230 can pass through the through hole from the outside of the front panel 170 door into the wide groove and be plugged together with the connecting rod 230.

[0102] Alternatively, those skilled in the art may also, as required, set a clearance hole at one end of the slide groove in the length direction for avoiding the rotating shaft 231, so that the rotating shaft 231 of the connecting rod 230 can be installed in the wide groove through the clearance hole. Furthermore, the front panel 170 may be provided with a component for shielding the clearance hole, and the component may be any feasible component.

[0103] 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.

[0104] like Fig.10 As shown, in some other embodiments of the present invention, compared with some embodiments described above, the cabinet 200 may further include an electric device 240, and the electric device 240 is at least used to drive the cabinet door 220 to open.

[0105] It can be understood by those skilled in the art that by configuring the cabinet 200 with an electric device 240 and enabling the electric device 240 to at least drive the cabinet door 220 to open, the cabinet 200 of the utility model can be automatically opened by the electric device 240, freeing the user's hands and improving the user's experience.

[0106] Continue reading Fig.10The electric device 240 includes an electric push rod 241 installed on the cabinet body 210 and a roller 242 installed at the telescopic end of the electric push rod 241, so that the electric device 240 abuts against the inner side surface of the cabinet door 220 through the roller 242.

[0107] Exemplarily, the telescopic end of the electric push rod 241 is set in a Y shape to form a space for arranging the roller 242. The roller 242 and the Y-shaped structure are rotatably fixed together through a pin shaft.

[0108] 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.

[0109] It is understood by those skilled in the art that, by making the electric device 240 include an electric push rod 241 installed on the cabinet body 210 and a roller 242 installed at the telescopic end of the electric push rod 241, the electric device 240 can be in rolling contact with the cabinet door 220 through the roller 242, thereby avoiding interference between the electric device 240 and the cabinet door 220. In addition, when the electric device 240 is powered off or damaged, the user can manually open the cabinet door 220, thereby ensuring that the air conditioner indoor unit 100 can work normally.

[0110] Those skilled in the art can also understand that, in other embodiments of the present invention, the cabinet door 220 is opened by the electric push rod 241 when the electric push rod 241 is extended, and can be automatically closed by gravity when the electric push rod 241 is shortened.

[0111] In addition, in other embodiments of the utility model, those skilled in the art may also set the electric device 240 to any other feasible device, such as a motor and a gear set, as needed. Exemplarily, the electric device 240 may include a motor, a housing 110 of the motor is fixedly connected to the cabinet body 210, and a drive shaft 1212 of the motor is fixedly connected to the cabinet door 220. When the motor rotates forward, the cabinet door 220 is driven to open, and when the motor rotates reversely, the cabinet door 220 is driven to close.

[0112] like Fig.10 As shown, in other embodiments of the present invention, the cabinet door 220 may be provided with an abutting structure 223. Moreover, the abutting structure 223 and the roller 242 are both magnetic components (components that can be attracted by a magnet), and at least one of the abutting structure 223 and the roller 242 is a magnet, so that the abutting structure 223 and the roller 242 are attracted together.

[0113] Those skilled in the art will appreciate that by providing an abutment structure 223 on the cabinet door 220, and providing both the abutment structure 223 and the roller 242 as magnetic components, and making at least one of the abutment structure 223 and the roller 242 a magnet, the abutment structure 223 and the roller 242 are attracted together, thereby avoiding the occurrence of a gap between the cabinet door 220 and the cabinet body 210 after the cabinet door 220 is closed.

[0114] Furthermore, the abutting structure 223 may be a metal sheet or a magnetic sheet adhered to the cabinet door 220 .

[0115] Those skilled in the art can understand that, in order to ensure that the electric device 240 and the cabinet door 220 can abut against each other, at least a portion of the projection of the electric device 240 on the plane where the cabinet door 220 is located falls within the area where the cabinet door 220 is located.

[0116] In addition, those skilled in the art may also set a sink groove on the cabinet body 210 as needed, and embed the electric device 240 into the sink groove, so as to ensure that at least part of the projection of the electric device 240 on the plane where the cabinet door 220 is located falls within the area where the cabinet door 220 is located. At the same time, the overall aesthetics of the cabinet 200 is also ensured.

[0117] like Fig.11 As shown, the utility model further provides an air conditioner 001, which includes an air conditioner outdoor unit 300 and an air conditioner indoor unit 100 described in any of the above embodiments.

[0118] When the air conditioner 001 is cooling, the air conditioner outdoor unit 300 releases heat, and the air conditioner indoor unit 100 absorbs the heat to cool the room.

[0119] 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.

[0120] Those skilled in the art will appreciate that the air conditioner 001 generally requires the use of its refrigeration system to perform cooling or heating.

[0121] 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.

[0122] Among them, the compressor and the pressure reducing member are generally provided in the air conditioner outdoor unit 300 .

[0123] Furthermore, a heat exchanger 140 is disposed in each of the air-conditioning outdoor unit 300 and the air-conditioning indoor unit 100 .

[0124] 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.

[0125] 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).

[0126] 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).

[0127] 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).

[0128] 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).

[0129] 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.

[0130] When the air conditioner 001 is heating, the heat exchanger 140 in the air conditioner outdoor unit 300 is used as an evaporator, and the heat exchanger 140 in the air conditioner indoor unit 100 is used as a condenser.

[0131] When the air conditioner 001 is cooling, the heat exchanger 140 in the air conditioner outdoor unit 300 is used as a condenser, and the heat exchanger 140 in the air conditioner indoor unit 100 is used as an evaporator.

[0132] 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.

[0133] 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.

[0134] 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.
