[0050] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0051] The following is for reference. Figures 1-12 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0052] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 According to an embodiment of the present invention, an air conditioner 100 includes a housing 1, a door opening and closing assembly 2, a door opening and closing drive assembly 3, and a heat exchange and air supply assembly. The housing 1 has an air inlet 12 and an air outlet 11. For example, the air conditioner 100 can be a split-type floor-standing air conditioner 100. The air conditioner 100 includes an indoor unit and an outdoor unit. The indoor unit includes a housing 1, a door opening and closing assembly 2, a door opening and closing drive assembly 3, and a heat exchange and air supply assembly. The housing 1 can play a role in dust prevention and protection for the components inside the housing 1. The air inlet 12 on the housing 1 is used to transport indoor or outdoor air into the housing 1. The air outlet 11 is used to discharge the air after heat exchange by the heat exchange and air supply assembly to the room. For example, the air inlet 12 is located at the rear of the housing 1, and the air outlet 11 is located at the front of the housing 1.

[0053] For example, the housing 1 may include a front housing component, a rear housing component, a top cover, and a base. An air inlet 12 may be formed on the rear housing component, and an air outlet 11 may be formed on the front housing component. The front housing component is connected to the front side of the rear housing component, the top cover is provided on the top of both the front and rear housing components, and both the front and rear housing components are mounted on the base, which serves to support the front and rear housing components.

[0054] The door opening and closing assembly 2 includes two doors 21 that are movable circumferentially along the housing 1. When the door opening and closing assembly 2 is in the closed air outlet 11 position, the two doors 21 are arranged in the left-right direction and together close the air outlet 11. The door opening and closing drive assembly 3 is connected to the door opening and closing assembly 2 to drive the doors 21 to move. The movement of the two doors 21 can close or open the air outlet 11. With the width of the air outlet 11 of the whole unit remaining unchanged, when the door opening and closing assembly 21 of the air conditioner 100 moves between the open air outlet 11 position and the closed air outlet 11 position, the two doors 21 move circumferentially to open to the sides or retract from the sides towards the center of the air conditioner 100 in the left-right direction, which can shorten the time consumed by the door opening and closing assembly 21 of the air conditioner 100.

[0055] For example, the two doors 21 can move toward each other to close the air outlet 11; or, the two doors 21 can move away from each other to open the air outlet 11. When the door assembly 2 is in the position where the air outlet 11 is open, that is, when the two doors 21 are in the position where the air outlet 11 is open, the two doors 21 can be located on the left and right sides of the air outlet 11 respectively.

[0056] The door opening / closing drive assembly 3 is connected to the door opening / closing assembly 2 and provides power to the door opening / closing assembly 2 to drive it to move, thereby closing or opening the air outlet 11. For example, the door opening / closing drive assembly 3 can be fixed to the heat exchange air supply assembly.

[0057] The heat exchange air supply assembly is used to heat or cool the air supplied to the heat exchange air supply unit through the air inlet 12 and discharge it from the air outlet 11. For example, air enters the casing 1 from the air inlet 12, exchanges heat with the heat exchanger assembly, and is discharged into the room from the air outlet 11, thereby regulating the indoor temperature.

[0058] For example, the heat exchange and air supply assembly may include a heat exchanger component, a duct component, and an air outlet frame component 4. The heat exchanger component is located between the air inlet 12 and the duct component. The air outlet frame component 4 is connected to the front side of the duct component and may be located inside the front housing component. The duct component includes a duct volute and a fan wheel. At least a portion of the fan wheel is located inside the duct volute, and the duct volute forms a duct. The air outlet frame component 4 forms an air outlet channel 41, which is located downstream of the duct and communicates with it. The air outlet side of the air outlet channel 41 is opposite to the air outlet 11.

[0059] When the door assembly 2 is in the closed air outlet 11 position, a sealing structure 22 is provided on the side of the two doors 21 adjacent to each other in the left-right direction. The sealing structures 22 on the two doors 21 are sealed together, and the heat exchange air supply assembly is located inside the housing 1. Here, the side of the two doors 21 adjacent to each other refers to the side of the two doors 21 that are close to each other when the door 21 is in the closed air outlet 11 position.

[0060] For example, the sealing structure 22 can be snapped onto the switch door 21 or connected by adhesive. Through the sealing engagement of the sealing structures 22 on the two switch doors 21, on the one hand, the impact force between the two switch doors 21 is reduced as they move towards each other to the position where the air outlet 11 is closed; on the other hand, when the switch door assembly 2 is in the position where the air outlet 11 is closed, the sealing engagement of the sealing structures 22 on the two switch doors 21 seals the gap between them. Thus, when the air conditioner 100 is not working, it can effectively reduce or prevent dust from the outside of the casing 1 from entering the casing 1 through the gap between the two switch doors 21 and accumulating dust, avoiding safety hazards and extending the service life of the air conditioner 100.

[0061] According to the embodiment of the present utility model, the air conditioner 100 has a sealing structure 22 on one side of the two switch doors 21 adjacent to each other. When the switch door assembly 2 is in the position of closing the air outlet 11, the sealing structure 22 on the two switch doors 21 is sealed in the left and right direction, which can seal the gap between the two switch doors 21. In this way, when the air conditioner 100 is not working, it can effectively reduce or prevent dust from the outside of the casing 1 from entering the casing 1 through the gap between the two switch doors 21 and forming dust accumulation, avoiding safety hazards and extending the service life of the air conditioner 100.

[0062] Reference Figure 1 , Figure 11 and Figure 12According to some embodiments of the present invention, the door opening and closing drive assembly 3 includes two door opening and closing drive mechanisms 31, each door opening and closing drive mechanism 31 includes a drive motor, one of the two door opening and closing drive mechanisms 31 is connected to one of the door opening and closing mechanisms 21, and the other of the two door opening and closing drive mechanisms 31 is connected to the other door opening and closing mechanism 21.

[0063] The door opening / closing drive mechanism 31 is used to drive the door 21 to open or close; the drive motor provides power for the movement of the air conditioner's door 21. By connecting one of the two door opening / closing drive mechanisms 31 to one door 21 and the other to the other door 21, a single door opening / closing drive mechanism 31 is connected to a single door 21, which facilitates the independent opening and closing of a single door 21. When there is little foot traffic indoors and people are concentrated on one side, the door 21 on the side furthest from the crowd can be closed independently, which helps reduce the energy consumption of the air conditioner 100.

[0064] When the door opening and closing assembly 2 includes two doors 21, the door opening and closing drive assembly 3 includes two door opening and closing drive mechanisms 31. One of the two door opening and closing drive mechanisms 31 is connected to one of the doors 21, and the other door opening and closing drive mechanism 31 is connected to the other door 21. This allows each door 21 to be driven by an independent door opening and closing drive mechanism 31, so that the movement of the two doors 21 can be independent of each other, and the independent control of a single door opening and closing mechanism 21 can be achieved.

[0065] For example, when the required air outlet area is low, one of the switch doors 21 can be positioned with the air outlet 11 open, and the other switch door 21 can be positioned with the air outlet 11 closed, thus concentrating the air outlets 11. For example, when it is necessary to concentrate the airflow from the air conditioner 100 to the front left of the air conditioner 100, the left switch door 21 can be positioned with the air outlet 11 open, and the right switch door 21 can be positioned with the air outlet 11 closed. For example, when it is necessary to concentrate the airflow from the air conditioner 100 to the front right of the air conditioner 100, the right switch door 21 can be positioned with the air outlet 11 open, and the left switch door 21 can be positioned with the air outlet 11 closed. For example, when a large air outlet area and air volume are required, both switch doors 21 can be positioned with the air outlets 11 open.

[0066] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7According to some embodiments of this utility model, the sealing structure 22 includes a sealing strip 221, which includes a fixing part 222 and a sealing part 223. The fixing part 222 is fixed to the switch door 21. When the switch door assembly 2 is in the closed position of the air outlet 11, the sealing parts 223 on the two switch doors 21 are in sealing contact in the left-right direction. The sealing strip 221 is fixed to the switch door 21 by the fixing part 222. For example, the fixing part 222 can be snapped onto the switch door 21, and the fixing part 222 and the sealing part 223 can be integrally formed. Fixing the sealing strip 221 to the switch door 21 by the fixing part 222 increases its stability and prevents misalignment during opening and closing of the door 21, thus preventing a reduction in the sealing effect of the sealing structure 22.

[0067] When the two doors 21 are in the closed air outlet 11 position, the sealing parts 223 on the two doors 21 can contact each other in the left-right direction, thereby sealing the gap between the two doors 21. Furthermore, because the sealing parts 223 of the two doors 21 contact each other in the left-right direction, during the movement of the two doors 21 from the open air outlet 11 position to the closed air outlet 11 position, the sealing parts 223 on the two doors 21 can contact each other before the two doors 21 come into contact. This effectively reduces the impact noise and frictional wear when the two doors 21 close, which helps to extend the service life of the doors 21.

[0068] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 According to some embodiments of the present invention, the sealing strip 221 further includes a first extension 224, which is connected to the rear side of the sealing part 223 and protrudes from the switch door 21 in a rearward direction. A receiving space 13 for accommodating the switch door 21 is defined between the heat exchange air supply assembly and the housing 1. When the switch door 21 is in the position of opening the air outlet 11, at least a portion of the switch door 21 is accommodated in the receiving space 13. The first extension 224 abuts against the end of the heat exchange air supply assembly near the air outlet 11.

[0069] The fact that at least a portion of the door 21 is accommodated in the accommodating space 13 may include the following situations: for example, a portion of the door 21 may be accommodated in the accommodating space 13; or, for another example, the entire door 21 may be accommodated in the accommodating space 13.

[0070] An accommodating space 13 is defined between the air outlet frame component 4 and the housing 1 to accommodate the switch door 21. When the switch door 21 is in the position of opening the air outlet 11, the switch door 21 is accommodated in the accommodating space 13, making the overall structure of the switch door 21 and the air outlet frame component 4 compact.

[0071] The first extension 224 of the sealing strip 221 is connected to the rear side of the sealing part 223 and protrudes from the switch door 21 in a rearward direction. This allows the first extension 224 of the sealing strip 221 to be located in the air outlet 41 and abut against the end of the heat exchange air supply assembly near the air outlet 11 when the switch door 21 is in the open air outlet 11 position. This seals the gap between the heat exchange air supply assembly and the switch door 21, preventing airflow in the air outlet 41 from flowing into the receiving space 13 through the gap between the heat exchange air supply assembly and the switch door 21 and causing air leakage. This prevents noise, condensation, and other problems caused by air leakage.

[0072] For example, when the door 21 is in the position of the open air outlet 11 and the air conditioner 100 is cooling, the first extension 224 of the sealing strip 221 can seal the gap between the air outlet frame component 4 and the door 21, preventing cold air in the air outlet duct 41 from entering the accommodating space 13 when the air conditioner 100 is cooling, thus causing condensation to occur in the accommodating space 13.

[0073] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the heat exchange and air supply assembly includes a heat exchanger component, an air duct component, and an air outlet frame component 4. The heat exchanger component is located between the air inlet 12 and the air duct component. The air outlet frame component 4 is connected to the front side of the air duct component and forms an air outlet channel 41. The air outlet side of the air outlet channel 41 faces the air outlet 11. The airflow entering from the air inlet 12 flows through the heat exchanger component and the air duct component, then flows through the air outlet frame component 4, through the air outlet channel 41, and is discharged into the room through the air outlet 11. The heat exchanger component can heat or cool the air supplied to the heat exchange and air supply unit from the air inlet 12 and send it into the air duct component. The air duct component is used to discharge the heated or cooled air from the heat exchanger component through the air outlet channel 41 toward the air outlet 11. The air outlet frame component 4 can effectively guide and regulate the airflow, so that the air discharged from the air outlet 11 is evenly distributed to all corners of the room.

[0074] An accommodating space 13 is defined between the air outlet frame component 4 and the housing 1 to accommodate the switch door 21. When the switch door 21 is in the position where the air outlet 11 is open, the switch door 21 is accommodated in the accommodating space 13, and at least a portion of the first extension 224 is located within the air outlet channel 41 and abuts against the air outlet frame component 4. The fact that at least a portion of the first extension 224 is located within the air outlet channel 41 and abuts against the air outlet frame component 4 can include the following situations: for example, a portion of the first extension 224 may be located within the air outlet channel 41 and abuts against the air outlet frame component 4; or, for another example, the entire first extension 224 may be located within the air outlet channel 41 and abuts against the air outlet frame component 4.

[0075] The first extension 224 can not only block the airflow in the air outlet 41 from flowing into the accommodating space 13, but also play a guiding role, so that the airflow in the air outlet 41 flows more smoothly toward the air outlet 11.

[0076] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, when the switch door 21 is in the position of opening the air outlet 11, the first extension 224 on the left side of the switch door 21 extends to the left in a direction from back to front and / or the first extension 224 on the right side of the switch door 21 extends to the right in a direction from back to front.

[0077] By extending to the left at an angle from back to front via the first extension 224 on the left-side switch door 21, at least part of the airflow in the air outlet duct 41 can be guided, especially the part of the airflow near the left-side switch door 21, to be directed towards the left side of the air conditioner 100, thereby enhancing the air supply effect on the left side of the air conditioner 100. This can increase the air outlet range of the air conditioner 100 and help improve the cooling / heating effect of the air conditioner 100.

[0078] By extending to the right at an angle from back to front via the first extension 224 on the right-side switch door 21, at least part of the airflow in the air outlet duct 41 can be guided, especially the part of the airflow near the right-side switch door 21, to be directed towards the right side of the air conditioner 100, thereby enhancing the air supply effect on the right side of the air conditioner 100. This can increase the air outlet range of the air conditioner 100 and help improve the cooling / heating effect of the air conditioner 100.

[0079] Reference Figure 2 and Figure 3 According to some embodiments of this utility model, the air outlet frame component 4 includes an air outlet frame body 42 and a second extension 43. The second extension 43 is connected to the front side of the air outlet frame body 42. When the switch door 21 is in the position of opening the air outlet 11, the first extension 224 and the second extension 43 abut against each other in the circumferential direction of the housing 1. When the switch door 21 is in the position of opening the air outlet 11, the second extension 43 is connected to the front side of the air outlet frame body 42, which facilitates the abutment of the first extension 224 and the second extension 43, effectively reducing the fitting gap between the air outlet frame component 4 and the switch door 21, thereby enhancing the sealing effect of the fitting gap between the air outlet frame component 4 and the switch door 21. This effectively prevents the airflow in the air outlet channel 41 from flowing into the receiving space 13 through the fitting gap between the air outlet frame component 4 and the switch door 21, thus preventing air leakage problems such as noise and condensation caused by air leakage.

[0080] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, a receiving groove 431 is formed on the side of the second extension 43 facing the air outlet 41. When the door 21 is in the position of opening the air outlet 11, the end of the first extension 224 near the air outlet frame component 4 is received in the receiving groove 431. When the door 21 is in the position of opening the air outlet 11, the end of the first extension 224 near the air outlet frame component 4 is received in the receiving groove 431. In the direction of airflow, the first extension 224 and the second extension 43 can fit more closely together, reducing the influence of the first extension 224 on the airflow and allowing the airflow to flow more smoothly from the air outlet frame component 4 towards the air outlet 11.

[0081] For example, the second extension 43 does not accommodate the groove 431. Since the first extension 224 and the second extension 43 abut against each other in the circumferential direction of the housing 1, the first extension 224 is located on the side of the second extension 43 near the air outlet 41 and protrudes from the surface of the second extension 43 facing the air outlet 41, causing the first extension 224 to block the airflow. The groove 431 is formed on the side of the second extension 43 facing the air outlet 41. When the door 21 is in the position of opening the air outlet 11, the end of the first extension 224 near the air outlet frame component 4 is accommodated in the groove 431, which can make the first extension 224 and the second extension 43 fit more tightly, reducing the volume of the first extension 224 protruding from the surface of the second extension 43 facing the air outlet 41. This can reduce the influence of the first extension 224 on the airflow.

[0082] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 According to some embodiments of this utility model, sealing protrusions 2231 are formed on the side of the sealing portions 223 of the two switch doors 21 adjacent to each other. When the switch doors 21 are in the closed air outlet 11 position, the sealing protrusions 2231 on the two switch doors 21 can contact and press against each other. By providing sealing protrusions 2231 on the sealing portions 223, the sealing portions 223 can deform when they contact each other, and the sealing protrusions 2231 can also play a better sealing role, preventing fine particles such as dust from entering the interior of the air conditioner 100 from the mating gap between the two switch doors 21.

[0083] For example, the sealing protrusion 2231 can be a spherical protrusion or a square protrusion, etc.

[0084] Reference Figure 6 and Figure 7According to some embodiments of this utility model, a sealing cavity 2232 is formed within the sealing portion 223. By forming a sealing cavity 2232 within the sealing portion 223, the sealing portion 223 can have better elastic deformation capability. For example, when the door assembly 2 is in the closed position of the air outlet 11, the sealing portions 223 of the sealing strips 221 on the two doors 21 come into contact and are squeezed against each other, thereby generating elastic deformation. After being squeezed, the sealing cavity 2232 is compressed, which can better seal the fitting gap between the two doors 21.

[0085] For example, the sealed cavity 2232 can be a non-sealed cavity connected to the outside world, or it can be a sealed cavity.

[0086] Reference Figure 3 , Figure 6 and Figure 7 According to some embodiments of the present invention, the switch door 21 includes a door body 211 and a reinforcing plate 212. The reinforcing plate 212 is disposed on the inner side of the door body 211, and a plurality of first cavities 2124 are spaced apart along the width direction of the door body 211 between the reinforcing plate 212 and the door body 211. The first cavities 2124 extend in the vertical direction. For example, the plurality of first cavities 2124 spaced apart along the width direction of the door body 211 can be 2, 4, 6, 8, 10, etc.

[0087] The reinforcing plate 212 provides support for the door 211, thereby increasing the structural strength of the door 21 and reducing the step difference between the two doors 21 of the air conditioner 100. By placing the reinforcing plate 212 on the inside of the door 211, the internal space of the air conditioner 100 can be effectively utilized, improving the space utilization rate of the air conditioner 100 and reducing the space occupied by the air conditioner 100 as a whole due to the reinforcing plate 212 being placed on the outside of the air conditioner 100.

[0088] The reinforcing plate 212 is disposed on the inner side of the door body 211 and defines a plurality of first cavities 2124 spaced apart along the width direction of the door body 211. This can increase the compressive strength and stability of the door 21, making it less susceptible to damage from external forces. The plurality of first cavities 2124 defined between the reinforcing plate 212 and the door body 211 can also improve the bending strength of the door 21, improve stress distribution, and extend the service life of the door 21. By setting a plurality of first cavities 2124, the amount of material used can be reduced while ensuring the support strength, thereby reducing the cost and the weight of the door 21 of the air conditioner 100, thus reducing the load on the air conditioner 100.

[0089] In the description of this utility model, "multiple" means two or more.

[0090] Reference Figure 8 and Figure 9 According to some embodiments of this utility model, in the width direction of the door body 211, the reinforcing plate 212 extends from one end of the door body 211 to the other end. For example, the width direction of the door body 211 can refer to the dimension of the door body 211 along the circumferential direction of the housing 1. The extension of the reinforcing plate 212 from one end of the door body 211 to the other end increases the coverage area of ​​the reinforcing plate 212 on the door body 211, thereby increasing the stability of the connection between the reinforcing plate 212 and the door body 211, and providing better support for the door body 211.

[0091] Reference Figure 8 and Figure 9 According to some embodiments of this utility model, the reinforcing plate 212 is made of aluminum alloy. Aluminum alloy has the characteristics of being lightweight, low-cost, and highly stable. By using aluminum alloy to make the reinforcing plate 212, the weight of the reinforcing plate 212 can be reduced, making it easier to install, reducing the load on the air conditioner 100's opening and closing door 21, preventing deformation of the air conditioner 100's opening and closing door 21, and the good stability of aluminum alloy can extend the service life of the opening and closing door 21.

[0092] Reference Figure 3 , Figure 4 , Figure 6 and Figure 8 According to some embodiments of the present invention, the reinforcing plate 212 includes a reinforcing plate body 2121 and a reinforcing structure 2122. The reinforcing structure 2122 is disposed on the side of the reinforcing plate body 2121 near the door body 211. The reinforcing structure 2122 includes a plurality of reinforcing protrusions 2123 arranged along the width direction of the door body 211. The door body 211, the reinforcing plate body 2121 and the plurality of reinforcing protrusions 2123 together define a plurality of first cavities 2124.

[0093] The reinforcing plate 2121 serves as the main part of the reinforcing plate 212 that supports the door 211, while the reinforcing protrusions 2123 of the reinforcing structure 2122 serve to improve the supporting strength of the reinforcing plate 2121. For example, the reinforcing protrusions 2123 can directly contact the door 211 to provide support; or the reinforcing protrusions 2123 may not directly contact the door 211.

[0094] By using protrusions to define multiple first cavities 2124 on the side of the reinforcing plate 2121 near the door body 211, the compressive strength and stability of the door 21 can be increased, making the door 21 less susceptible to damage from external forces. The multiple first cavities 2124 defined between the reinforcing plate 212 and the door body 211 can also improve the bending strength of the door 21, improve stress distribution, and extend the service life of the door 21. By setting multiple first cavities 2124, the amount of material used can be reduced while ensuring support strength, thus reducing costs and lightening the weight of the door 21 of the air conditioner 100, thereby reducing the load on the air conditioner 100.

[0095] Reference Figure 3 , Figure 4 and Figure 6 According to some embodiments of this utility model, the reinforcing protrusion 2123 is formed as a reinforcing rib frame, and a second cavity 2125 is defined within the reinforcing rib frame. The second cavity 2125 extends in the vertical direction, and the second cavity 2125 and the first cavity 2124 are arranged along the width direction of the door body 211. For example, the reinforcing rib frame can be multiple reinforcing rib frames arranged along the width direction of the door body 211. The reinforcing rib frames can be connected to each other on the side closest to the door body 211, thereby defining the second cavity 2125. By arranging the second cavity 2125 and the first cavity 2124 sequentially along the width direction of the door body 211, the bending strength of the reinforcing plates 212 at different positions can be increased, and the overall bending strength of the opening and closing door 21 can also be enhanced, enabling the opening and closing door 21 to withstand stresses in different directions.

[0096] Reference Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 According to some embodiments of the present invention, the inner side of the door body 211 is provided with an elastic buckle 2111 and a limiting buckle 2113. The elastic buckle 2111 and the limiting buckle 2113 are located at both ends in the width direction of the door body 211. The limiting buckle 2113 and the door body 211 define a slot 2114. The reinforcing plate 212 is provided with a limiting rib 2128 extending along the length direction of the reinforcing plate 212. The end of the reinforcing plate 212 away from the other opening and closing door 21 forms a side portion 2129. At least a portion of the side portion 2129 is inserted into the slot 2114. The buckling portion 2112 of the elastic buckle 2111 abuts against the limiting rib 2128 in the thickness direction of the door body 211, and the buckling portion 2112 of the elastic buckle 2111 is located on the side of the limiting rib 2128 away from the door body 211. The insertion slot 2114 of the side portion 2129 may include, for example, a partial insertion slot 2114 of the side portion 2129; or, for example, all insertion slots 2114 of the side portion 2129.

[0097] By inserting at least a portion of the side portion 2129 into the slot 2114, a plug-in connection can be achieved between the reinforcing plate 212 and the door body 211, making the overall structure of the reinforcing plate 212 and the door body 211 compact. The limiting buckle 2113 also limits the side portion 2129, reducing or preventing the possibility of relative movement of the reinforcing plate 212 relative to the door body 211 along the width direction of the door body 211, thus enhancing the stability of the connection between the reinforcing plate 212 and the door body 211. The locking portion 2112 of the elastic buckle 2111 abuts against the limiting rib 2128 in the thickness direction of the door body 211, limiting the reinforcing plate 212 and reducing or preventing the possibility of relative movement of the reinforcing plate 212 relative to the door body 211 in the thickness direction of the door body 211.

[0098] By providing elastic buckles 2111 and limiting buckles 2113 at both ends of the door body 211 in the width direction, and defining a slot 2114 between the limiting buckle 2113 and the door body 211, and having the buckling part 2112 of the elastic buckle 2111 abutting against the limiting rib 2128 and at least a portion of the side part 2129 of the reinforcing plate 212 inserted into the slot 2114, the reinforcing plate 212 can play a bidirectional limiting role at both ends of the door body 211 in the width direction, effectively enhancing the stability of the connection between the reinforcing plate 212 and the door body 211.

[0099] Reference Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 According to some embodiments of this utility model, the reinforcing protrusion 2123 is formed as a reinforcing rib frame, and a second cavity 2125 is defined within the reinforcing rib frame. The second cavity 2125 extends in the vertical direction, and the second cavity 2125 and the first cavity 2124 are arranged along the width direction of the door body 211. A limiting rib 2128 is provided in the reinforcing rib frame and is located outside the second cavity 2125. At least a portion of the elastic buckle 2111 is located within the first cavity 2124. The fact that at least a portion of the elastic buckle 2111 is located within the first cavity 2124 can include the following situations: for example, a portion of the elastic buckle 2111 may be located within the first cavity 2124; or, for another example, all of the elastic buckle 2111 may be located within the first cavity 2124.

[0100] With the limiting rib 2128 provided on the reinforcing rib frame and the limiting rib 2128 located outside the second cavity 2125, the reinforcing rib frame can support the limiting rib 2128. With at least a part of the elastic buckle 2111 located in the first cavity 2124, the space between the reinforcing plate 212 and the door body 211 can be fully utilized. While realizing the connection between the elastic buckle 2111 and the limiting rib 2128, the overall structure of the reinforcing plate 212 and the door body 211 is compact.

[0101] Reference Figures 6-9 According to some embodiments of this utility model, the switch door 21 includes a door body 211 and a reinforcing plate 212. The reinforcing plate 212 is disposed on the inner side of the door body 211, and the sealing structure 22 is disposed on the reinforcing plate 212. The reinforcing plate 212 can improve the overall structural strength of the switch door 21, and the sealing structure 22 is disposed on the reinforcing plate 212, so that the reinforcing plate 212 can support the sealing structure 22. Moreover, since the reinforcing plate 212 is disposed on the inner side of the door body 211, the sealing structure 22 can also be disposed on the inner side of the door body 211. In this way, during the process of the two switch doors 21 moving from the position of opening the air outlet 11 to the position of closing the air outlet 11, the sealing structure 22 disposed on the inner side of the door body 211 can first contact each other before the two door bodies 211 come into contact, so as to effectively reduce the impact sound and friction wear of the two switch doors 21 closing, which is beneficial to extending the service life of the switch door 21.

[0102] Reference Figures 6-9 According to some embodiments of this utility model, the sealing structure 22 includes a sealing strip 221, which includes a fixing part 222 and a sealing part 223. The fixing part 222 is fixed to the switch door 21. When the switch door assembly 2 is in the closed position of the air outlet 11, the sealing parts 223 on the two switch doors 21 are in sealing contact in the left-right direction. The reinforcing plate 212 is provided with a mounting groove 2127, and at least a portion of the fixing part 222 is accommodated in the mounting groove 2127. The at least portion of the fixing part 222 being accommodated in the mounting groove 2127 can include the following situations: for example, a portion of the fixing part 222 may be accommodated in the mounting groove 2127; or, for another example, the entire fixing part 222 may be accommodated in the mounting groove 2127.

[0103] By providing an installation groove 2127 on the reinforcing plate 212, it is easier to assemble the sealing strip 221 on the reinforcing plate 212. By having at least a portion of the fixing part 222 accommodated in the installation groove 2127, the connection between the sealing strip 221 and the reinforcing plate 212 is realized, and the overall structure of the sealing strip 221 and the reinforcing plate 212 is also more compact.

[0104] Reference Figures 6-9According to some embodiments of the present invention, the fixing part 222 includes an anti-detachment section 2221 and an installation section 2222. The anti-detachment section 2221 is accommodated in the installation groove 2127, and at least a portion of the installation section 2222 is clamped between the door body 211 and the reinforcing plate 212. The clamping of at least a portion of the installation section 2222 between the door body 211 and the reinforcing plate 212 can include the following situations: for example, a portion of the installation section 2222 may be clamped between the door body 211 and the reinforcing plate 212; or, for another example, the entire installation section 2222 may be clamped between the door body 211 and the reinforcing plate 212.

[0105] By having at least a portion of the mounting section 2222 sandwiched between the door body 211 and the reinforcing plate 212, and the anti-detachment section 2221 accommodated in the mounting groove 2127, the stability of the connection between the fixing part 222 and the reinforcing plate 212 can be enhanced, effectively reducing or avoiding the possibility of the sealing strip 221 falling off the reinforcing plate 212.

[0106] Reference Figures 6-10 According to some embodiments of this utility model, the inner side of the door body 211 is provided with a pressing rib 2115, which abuts against the mounting section 2222. By abutting against the mounting section 2222 with the pressing rib 2115, the mounting section 2222 can be pressed between the door body 211 and the reinforcing plate 212, reducing or avoiding the possibility of relative movement between the mounting section 2222 and the door body 211 or the reinforcing plate 212. This can further improve the stability of the connection of the sealing strip 221 on the reinforcing plate 212.

[0107] Reference Figures 6-9 According to some embodiments of the present invention, the reinforcing plate 212 includes a reinforcing plate body 2121 and a reinforcing structure 2122. The reinforcing structure 2122 is disposed on the side of the reinforcing plate body 2121 near the door body 211. The reinforcing structure 2122 includes a plurality of reinforcing protrusions 2123 arranged along the width direction of the door body 211. The reinforcing protrusions 2123 are formed as reinforcing rib frames. A second cavity 2125 is defined in the reinforcing rib frame. The second cavity 2125 extends in the vertical direction. At least a portion of the reinforcing rib frame has a through hole 2126. The second cavity 2125 defined by the reinforcing rib frame with the through hole 2126 constitutes a mounting groove 2127. A portion of the mounting section 2222 passes through the through hole 2126. The through hole 2126 makes it easier to assemble the fixing part 222 on the reinforcing plate 212. Since the anti-detachment section 2221 is accommodated in the mounting groove 2127, and the mounting section 2222 passes through the through hole 2126, the fixing part 222 can be assembled on the reinforcing frame.

[0108] The presence of through holes 2126 on at least a portion of the reinforcing rib frame can include the following situations: for example, through holes 2126 may be formed on a portion of the reinforcing rib frame; or, for example, through holes 2126 may be formed on all the reinforcing rib frames.

[0109] Reference Figure 6 and Figure 7 According to some embodiments of the present invention, a notch 23 is formed on one side of each other adjacent to the two switch doors 21. The notch 23 is located at the front end of the switch door 21 and penetrates the front surface of the switch door 21. The notch 23 can reduce the step difference generated when the switch door 21 is in the closed position.

[0110] For example, step difference refers to the mismatch between the two switch doors 21 of the air conditioner 100 due to manufacturing precision deviation or external force, which causes interference when the two switch doors 21 are in the closed air outlet 11 position, such as collision or obstruction when the switch doors 21 are closed. By setting a notch 23 at the front end of the switch door 21 and the notch 23 penetrating the front surface of the switch door 21, the collision between the two switch doors 21 caused by the front-to-back misalignment when the switch door 21 is in the closed air outlet 11 position can be reduced, thereby reducing wear between the two switch doors 21 and extending the service life of the switch doors 21.

[0111] According to some embodiments of the present invention, the sealing structure 22 includes a sealing overlap, and when the door assembly 2 is in the position where the air outlet 11 is closed, the sealing overlaps on the two doors 21 are stacked in the front-to-back direction. By including a sealing overlap in the sealing structure 22, and stacking the sealing overlaps on the two doors 21 in the front-to-back direction when the door assembly 2 is in the position where the air outlet 11 is closed, the sealing effect can be further improved.

When the switch door assembly 2 is in the closed air outlet 11 position, the sealing parts 223 on the two switch doors 21 are in sealing contact in the left-right direction. The sealing strip 221 also includes a first extension 224, which is connected to the rear side of the sealing part 223 and protrudes from the switch door 21 in the rearward direction. When the switch door 21 is in the open air outlet 11 position, the first extension 224 and the second extension 43 abut against each other in the circumferential direction of the housing 1. A receiving groove 431 is formed on the side of the second extension 43 facing the air outlet channel 41. When the switch door 21 is in the open air outlet 11 position, the end of the first extension 224 near the air outlet frame component 4 is received in the receiving groove 431.
