Description

Technical Field

[0001] This invention relates to the field of home appliance technology, and in particular to an air conditioner. Background Technology

[0002] Some existing home appliances consist of a main unit and a sub-unit. The sub-unit is housed within the main unit and can operate independently. The main unit houses the sub-unit through a cavity, and some cavities have doors at their entrances and exits to protect the sub-unit inside. In some home appliances, the doors of the cavity are either slidably mounted inside the cavity (or inside the main unit) or on the outer surface of the main unit. This installation method results in the doors not being flush with the outer surface of the main unit when closed, and may even create a significant step, thus affecting the product's appearance.

[0003] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main objective of this invention is to propose an air conditioner that addresses the technical problem that the installation method of the door switch can easily affect the product's appearance in some air conditioners with such switches.

[0005] To achieve the above objectives, the air conditioner proposed in this invention includes a body and a door. The body is provided with a guide rail and a receiving cavity, the receiving cavity having an inlet and outlet. The door is equipped with guide wheels, which can roll within the guide rail to drive the door to move back and forth between an open position and a closed position. When the door moves to the open position, the door opens the inlet and outlet and is located inside the body; when the door moves to the closed position, the door closes the inlet and outlet and is located closer to the outside of the body than when it is in the open position. The guide rail includes an inclined switching section, which allows the door to switch between the open and closed positions.

[0006] In one embodiment, the switch door is a lifting door, and the guide wheel includes an upper guide wheel and a lower guide wheel. The upper guide wheel is installed at the upper end of the switch door, and the lower guide wheel is installed at the lower end of the switch door. When the switch door is in the closed position, the lower guide wheel is located within the switching section, and the upper guide wheel is located outside the guide rail. The guide rail is provided with an inlet and outlet for the upper guide wheel to enter and exit at the position corresponding to the upper guide wheel.

[0007] In one embodiment, the vertical segment includes an upper vertical segment and a lower vertical segment, the inlet and outlet are located at the lower end of the upper vertical segment, and the switching segment is located at the lower end of the lower vertical segment.

[0008] In one embodiment, the air conditioner further includes a push-pull assembly for pushing and pulling the switch door to pull the upper guide wheel in and out of the guide rail.

[0009] In one embodiment, the push-pull assembly includes a push-pull motor, a push-pull gear connected to the push-pull motor, a push-pull rack meshing with the push-pull gear, and a push-pull member fixed relative to the push-pull gear or the push-pull rack; the push-pull member is connected to the switch door and pushes and pulls the switch door when the push-pull motor drives the push-pull gear or the push-pull rack to move.

[0010] In one embodiment, the surface of the switch door facing the push-pull assembly is further provided with a guide groove, the guide groove extending along the lifting direction of the switch door, and the push-pull component is a guide pulley, which is slidably installed in the guide groove.

[0011] In one embodiment, the guide groove has a slot into which the guide pulley extends, the opening direction of the slot being parallel to the surface of the switch door, and the guide pulley being located between two groove walls of the guide groove and rollingly abutting against the groove walls of the guide groove.

[0012] In one embodiment, the air conditioner further includes a lifting assembly, which includes a lifting motor, a lifting gear connected to the lifting motor, and a lifting rack meshing with the lifting gear. The lifting rack extends along the lifting direction of the door and is fixed to the door.

[0013] In one embodiment, the air conditioner further includes a left side panel and a right side panel disposed opposite to each other, and the inlet / outlet is located between the left side panel and the right side panel; the air conditioner further includes a mounting assembly, the push-pull assembly and the lifting assembly are both mounted on the mounting assembly, the mounting assembly is rotatably mounted inside the body, and the rotation axis of the mounting assembly extends in the left-right direction.

[0014] In one embodiment, the mounting assembly includes a mounting frame and a mounting block. The mounting frame has a hollow structure and is rotatably connected to the machine body. The mounting block is slidably mounted in the mounting frame. The push-pull motor, the push-pull gear, the push-pull component, and the lifting assembly are all mounted on the mounting block, and the push-pull rack is fixed to the mounting frame.

[0015] In one embodiment, when the switch door is in the closed position, the upper end of the switch door corresponds to the mounting component, and at least two support bearings are also installed on the mounting block, the at least two support bearings rollingly abutting against the surface of the switch door facing the mounting component.

[0016] In one embodiment, the rotation axis of the lifting gear is parallel to the extension direction of the push-pull rack, and the switch door is also provided with a rack limiting groove with the slot facing the lifting gear, and the lifting rack is formed in the rack limiting groove; at least part of the teeth of the lifting gear extend into the rack limiting groove and mesh with the lifting rack.

[0017] In one embodiment, when the door is moved to the closed position, the surface of the door is flush with the outer surface of the body.

[0018] In one embodiment, the edge of the switch door is further provided with a limiting structure, and the inner side of the body is also equipped with a limiting beam. When the switch door moves to the closed position, the limiting structure abuts against the limiting beam.

[0019] In one embodiment, the air conditioner further includes a clearance door, a portion of the edge of which forms a portion of the edge of the entrance / exit, and the clearance door is also slidably connected to the unit body to change the size of the entrance / exit by sliding.

[0020] In one embodiment, the air conditioner further includes a sliding assembly for driving the clearance door to slide relative to the unit body.

[0021] In one embodiment, the sliding assembly includes a sliding motor, a sliding gear connected to the sliding motor, and a sliding rack meshing with the sliding gear; the sliding motor and the sliding gear are both fixed to the machine body, and the sliding rack has an arc-shaped structure and is fixed to the clearance door.

[0022] In one embodiment, the air conditioner further includes a sub-unit, which is detachably housed within the housing cavity.

[0023] In one embodiment, the cavity wall of the receiving cavity is further provided with guide rollers, which are used to guide the submachine when it enters the receiving cavity.

[0024] The air conditioner of the present invention opens and closes the entrance and exit of the accommodating cavity by means of a switch door. When the switch door moves to the open position, the switch door opens the entrance and exit and is located inside the body. Thus, while ensuring that the sub-unit can smoothly enter and exit the accommodating cavity, the switch door is hidden inside the body, avoiding the movement of the switch door from causing the entire device to occupy a large space.

[0025] When the door moves to the open position, it closes the entrance and exit, and is closer to the outside of the machine body than when it is in the open position. This protects the sub-machine while ensuring that the surface of the door is flush with or smoothly connected to the outer surface of the machine body. This avoids the formation of a large step between the door and the outer surface of the machine body when the entrance and exit are closed, which could affect the appearance of the product.

[0052] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0053] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0054] This invention proposes an air conditioner 10.

[0055] In embodiments of the present invention, such as Figures 1 to 4 As shown, the air conditioner 10 is an indoor unit, specifically a vertical indoor unit, and mainly includes a body 20 and a door 30. The body 20 has a roughly elongated cylindrical shape and is installed vertically indoors. Therefore, the air conditioner 10 has a relative upper and lower end during installation and use. The directional terms mentioned in this specification refer to the state of the air conditioner 10 during installation and use.

[0056] like Figure 5As shown, for a vertical air conditioner indoor unit, the air conditioner 10's body 20 mainly includes a long, cylindrical mounting shell 24, a supporting sheet metal strip 25, an evaporator assembly 26, an air duct assembly, an air outlet frame 27, a front panel 28, and side panels 29 (including a left side panel 291 and a right side panel 292), etc., installed inside the mounting shell 24. The mounting shell 24 has an internal cavity to accommodate the evaporator assembly 26, air duct assembly, and other components. The mounting shell 24 also has an air inlet and an air outlet communicating with its interior, both of which are equipped with grilles 23. The supporting sheet metal strip 25 is fixed inside the mounting housing 24 and is used to install and support the evaporator assembly 26, the air outlet frame 27, etc. In this embodiment, the supporting sheet metal strip 25 extends vertically and can be divided into an upper half and a lower half. The evaporator assembly 26, the air duct assembly, the air outlet frame 27, etc. are all fixedly installed in the upper half of the supporting sheet metal strip 25, so that space can be left at the lower end of the body 20 as a receiving cavity 21.

[0057] The evaporator assembly 26 mainly consists of a U-shaped tube and heat dissipation fins installed on the outside of the U-shaped tube. Refrigerant is introduced into the U-shaped tube, and during the flow of the refrigerant inside the U-shaped tube, it exchanges heat with the air around the U-shaped tube, thereby achieving cooling or heating of the indoor air. The specific structure of the evaporator assembly 26 can refer to existing evaporator structures, and no specific limitations are made here.

[0058] The air outlet frame 27 is fixed to the supporting sheet metal strip 25 and covers the evaporator assembly 26. The air outlet frame 27 is generally made of plastic material to reduce the weight of the entire air conditioner 10. The front panel 28, left side panel 291, right side panel 292 and other components are all fixedly connected to the air outlet frame 27.

[0059] After the front panel 28 is fixed to the air outlet frame 27, its outer surface, together with the outer surface of the mounting housing 24, constitutes the outer surface of the main unit of the device. The size, shape, and structure of the front panel 28 are not specifically limited here and can be set according to actual needs. For example, in this embodiment, such as... Figure 6 As shown, the front panel 28 has a semi-enclosed structure and includes a flat plate 281 and two arc-shaped plates 282 connected to both sides of the flat plate 281. The two arc-shaped plates 282 are connected to the air outlet frame 27, thereby fixing the front panel 28 to the body 20.

[0060] Please watch it again. Figures 1 to 4The main body 20 also includes a receiving cavity 21, which has an entrance / exit 211 for the sub-machine 100 to enter and exit. The sub-machine 100 can be a machine capable of intelligent movement and independent operation. To facilitate the sub-machine 100's entry and exit from the receiving cavity 21, the receiving cavity 21 is located at the lower end of the main body 20 near the ground. The size and shape of the receiving cavity 21 can be designed to accommodate the sub-machine 100, requiring only that it be large enough to hold it.

[0061] The entrance / exit 211 of the accommodating cavity 21 can be formed by a partial opening in the mounting housing 24, or it can be formed by the front panel 28, left side panel 291, right side panel 292, etc., being mounted on the mounting housing 24 and only partially enclosing the accommodating cavity 21, with the unenclosed portion of the accommodating cavity 21 forming the entrance / exit 211. In this embodiment, as... Figure 2 As shown, taking the sub-machine 100 as an example with a long cylindrical structure, the entrance / exit 211 is formed below the front panel 28, specifically below the flat plate 281 in the front panel 28, and the lower edge of the flat plate 281 forms the upper edge of the entrance / exit 211. The entrance / exit 211 is roughly rectangular and extends along the extension direction of the flat plate 281 to facilitate the smooth entry and exit of the sub-machine 100 with its long cylindrical structure.

[0062] It should be noted that the sub-unit 100 housed within the accommodating cavity 21 can be an independent air purifier, fan, humidifier, aromatherapy diffuser, etc. During operation, the sub-unit 100 can exit from the accommodating cavity 21 and move to other locations within the room, thus operating from a different position relative to the air conditioner 10. Therefore, it can be understood that the air conditioner 10 of the present invention, by providing an accommodating cavity 21 within its body 20 for housing the sub-unit 100, enables the entire product device including the air conditioner 10 to solve the technical problem of relatively fixed device positions and less than ideal performance by incorporating a movable and independently operating sub-unit 100.

[0063] In addition, such as Figures 1 to 4 As shown, the air conditioner 10 of the present invention is also provided with a switch door 30. The size of the switch door 30 is adapted to the inlet and outlet 211 of the accommodating cavity 21, or it can be slightly larger than the inlet and outlet 211 so as to completely close the inlet and outlet 211, thereby effectively protecting the unit 100 inside the accommodating cavity 21. For example, taking the inlet and outlet 211 as rectangular, the switch door 30 is roughly rectangular plate-like structure, and its size is just enough to close the inlet and outlet 211.

[0064] The switch door 30 is movably connected to the body 20 and can move back and forth between the open position and the closed position. When the switch door 30 moves to the open position, the switch door 30 opens the entrance 211 and is located inside the body 20. When the switch door 30 moves to the closed position, the switch door 30 closes the entrance 211 and is closer to the outside of the body 20 than when it is in the open position.

[0065] The door 30 can be slidably or rotatably connected to the body 20. When the door 30 is in the open position, the sub-machine 100 can exit from the accommodating cavity 21 or enter the accommodating cavity 21 from outside the body 20. That is, when the door 30 is in the open position, it can be completely exited from the entrance / exit 211, or partially remain within the entrance / exit 211, just enough for the sub-machine 100 to enter and exit. The specific opening position can be set according to actual conditions. Furthermore, in this invention, when the door 30 moves to the open position, it is located inside the body 20. This ensures that the sub-machine 100 can smoothly enter and exit the accommodating cavity 21 while concealing the door 30 inside the body 20, preventing the movement of the door 30 from causing the entire device to occupy a large space.

[0066] When the door 30 is in the closed position, the inlet / outlet 211 is completely closed to prevent foreign objects from entering the accommodating cavity 21. Furthermore, in this invention, when the door 30 is in the closed position, it is closer to the outer side of the unit 20 than when it is in the open position. This protects the sub-unit 100 while ensuring that the surface of the door 30 is flush with or smoothly connected to the outer surface of the unit 20, preventing a large step from forming between the door 30 and the outer surface of the unit 20 when the inlet / outlet 211 is closed, thus affecting the appearance of the air conditioner 10. For example, in this embodiment, when the door 30 is in the closed position and the inlet / outlet 211 of the accommodating cavity 21 is closed, the outer surface of the door 30 is flush with or nearly flush with the flat panel 281, thereby improving the appearance of the air conditioner 10.

[0067] There are several ways to ensure that the door 30 is closer to the outside of the machine body 20 when it is in the closed position compared to when it is in the open position. For example, in one embodiment, the door 30 is a lifting door, and it includes movement in two directions during both opening and closing. When the door 30 needs to switch from the closed position to the open position, it can first move a certain distance inward to the inside of the machine body 20, and then move upward to open the entrance 211; and when the door 30 needs to switch from the open position to the closed position, the operation is reversed.

[0068] For example, such as Figure 6 or Figure 19 As shown, in another embodiment, the body 20 is also provided with a guide rail 22, and the switch door 30 is also equipped with a guide wheel 31, which rolls on the guide rail 22; the guide rail 22 includes an inclined switching section 221, and when the guide wheel 31 slides on the switching section 221, the switch door 30 gradually switches to the open position or the closed position.

[0069] Specifically, in this embodiment, the opening / closing door 30 is a lifting door. The guide rail 22 includes a vertical section 222 and a switching section 221 inclined relative to the vertical section 222. The vertical section 222 extends in the vertical direction so that the opening / closing door 30 can move up and down along the vertical section 222 of the guide rail 22. The switching section 221, which is inclined relative to the vertical section 222 in the guide rail 22, is used to switch the opening / closing door 30 between the open position and the closed position, so that when the opening / closing door 30 moves to the closed position, it is closer to the outside of the body 20 than when it is in the open position.

[0070] The guide rail 22 may include two vertical sections 222, which are staggered. One vertical section 222 is closer to the outer side of the body 20 than the other vertical section 222. The two vertical sections 222 are connected by a switching section 221. When the door 30 moves to the vertical section 222 that is closer to the outer side of the body 20, the door 30 is approaching or has just reached the closing position.

[0071] Or, such as Figure 6 As shown, the guide rail 22 may also consist of only a vertical section 222. The switching section 221 can be connected to the lower end of the vertical section 222 and tilted outward relative to the vertical section 222 towards the outside of the body 20. When the door 30 moves from the vertical section 222 to the switching section 221, the door 30 will move downward while gradually moving outward towards the outside of the body 20. Thus, when the door 30 reaches the closed position, it will be closer to the outside of the body 20 than when it is in the open position. When the guide wheel 31 moves from the switching section 221 to the vertical section 222, the door 30 will move upward while gradually moving inward towards the inside of the body 20. Thus, when it reaches the open position, the door 30 is located inside the body 20.

[0072] To ensure the stability of the opening and closing door 30, multiple guide rails 22 can be provided inside the body 20. These guide rails 22 extend parallel to each other and are located on both sides of the sliding direction of the opening and closing door 30. Each guide rail 22 includes a vertical section 222 and a switching section 221. Multiple guide wheels 31 are also correspondingly provided on the opening and closing door 30, and are rolled within the guide rails 22. For example, in one embodiment, the opening and closing door 30 has a rectangular plate-like structure and moves up and down along its length when opening or closing. Four guide wheels 31 are provided on the opening and closing door 30, respectively located near the four corners of the door to ensure force balance and stable movement. Two guide rails 22 are provided inside the body 20, corresponding to the two long sides of the opening and closing door 30. Each guide rail 22 allows two guide wheels 31 on the corresponding side to slide, thereby driving the opening and closing door 30 to move together.

[0073] In one embodiment, please refer to Figure 2 and Figure 6 The opening and closing door 30 is a lifting door. The guide rail 22 also includes a vertically extending vertical section 222. The switching section 221 is connected to the lower end of the vertical section 222 and is inclined relative to the vertical section 222. The switching section 221 has a connecting end 221a and an end end 221b. The connecting end 221a is connected to the vertical section 222. When the guide wheel 31 slides to the end end 221b, the opening and closing door 30 reaches the closing position.

[0074] It is understandable that by moving the guide wheel 31 to the end point 221b of the switching section 221, which is exactly at the closed position, the closing position of the switch door 30 can be better controlled. In the design, the thickness of the switch door 30, the length of the switching section 221, the inclination, and the position of the end point 221b can be coordinated to ensure that the outer surface of the switch door 30 is flush with or smoothly connected to the outer surface of the body 20 when it is closed. This avoids the situation where a large step is formed between the switch door 30 and the outer surface of the body 20 when it is closed, which would affect the appearance.

[0075] Specifically, taking the example of a door 30 with four guide wheels 31 and two guide rails 22 inside the body 20, each guide rail 22 can have two vertical sections 222, which can be staggered or not staggered. Each vertical section 222 is connected to a switching section 221 at its lower end, meaning the two guide rails 22 have a total of four switching sections 221, each corresponding to one guide wheel 31. When each guide wheel 31 moves to the end point 221b of the switching section 221, the door 30 is in the closed position, closing the entrance / exit 211 of the accommodating cavity 21.

[0076] Of course, the guide rail 22 can also have switching sections 221 respectively corresponding to the two guide wheels 31 at the lower end of the switch door 30, while the inlet and outlet 223 corresponding to the two guide wheels 31 at the upper end of the switch door 30 can be respectively set up. When the two guide wheels 31 at the lower end of the switch door 30 move from the vertical section 222 to the switching section 221, the two guide wheels 31 at the upper end of the switch door 30 gradually disengage from the guide rail 22 from the inlet and outlet 223; when the two guide wheels 31 at the lower end of the switch door 30 move to the end point 221b of the switching section 221, the two guide wheels 31 at the upper end of the switch door 30 can be suspended in the air or supported by other structures inside the body 20.

[0077] For example, in one embodiment, such as Figure 14 and Figure 15 As shown, the guide wheel 31 includes an upper guide wheel 311 and a lower guide wheel 312, with two of each. The upper guide wheel 311 is installed at the upper end of the switch door 30, and the lower guide wheel 312 is installed at the lower end of the switch door 30. When the switch door 30 is in the closed position, the lower guide wheel 312 is located within the switching section 221, specifically at the end point 221b of the switching section 221. The upper guide wheel 311 is located outside the guide rail 22, and the guide rail 22 is provided with an inlet and outlet 223 for the upper guide wheel 311 to enter and exit at the position corresponding to the upper guide wheel 311.

[0078] In this embodiment, when the switch door 30 needs to be switched from the closed position to the open position to open the entrance 211 of the accommodating cavity 21, the upper end of the switch door 30 needs to be moved inward towards the body 20 first, ensuring that the upper guide wheel 311 reaches the entrance / exit 223 of the guide rail 22. At this time, the switch door 30 is relatively tilted, and its lower end and the lower guide wheel 312 can remain stationary or rotate around the axis of the lower guide wheel 312 at a certain angle. When the upper guide wheel 311 reaches the entrance / exit 223 of the guide rail 22 and can slide into the guide rail 22 at any time, the entire switch door 30 is driven to move upward. At this time, the upper guide wheel 311 enters the guide rail 22 and continues to roll, and the lower guide wheel 312 also gradually rolls from the switching section 221 of the guide rail 22 to the vertical section 222 and continues to roll upward within the vertical section 222 until the switch door 30 reaches the open position, thus completing the opening of the entrance / exit 211 of the accommodating cavity 21.

[0079] When the door 30 needs to move from the open position to the closed position, the operation can be reversed. Specifically, the upper guide wheel 311 and the lower guide wheel 312 move downwards simultaneously within the vertical section 222 of the guide rail 22. Just before reaching the closed position, the lower guide wheel 312 moves from the vertical section 222 to the switching section 221, until it reaches the end point 221b of the switching section 221. The upper end of the door 30 and the upper guide wheel 311 can disengage from the inlet / outlet 223 of the guide rail 22 under the influence of the lower end of the door 30, or the upper end of the door 30 can be pushed into the inlet / outlet 211 of the receiving cavity 21 by the drive assembly, ensuring that the door 30 extends vertically in the closed position and closes the inlet / outlet 211 of the receiving cavity 21.

[0080] Understandably, by positioning the upper guide wheel 311 of the door 30 outside the guide rail 22 when it is in the closed position, when the outlet of the receiving cavity 21 needs to be opened, the upper end of the door 30 must first move a certain distance inward towards the body 20 until the upper guide wheel 311 of the door 30 moves to the inlet / outlet 223 of the guide rail 22 before the door 30 can begin its upward movement. This arrangement not only avoids interference between the door 30 and the lower end of the front panel 28 during upward movement, thus preventing obstruction, but also reduces the resistance to the upward movement of the door 30, ensuring smooth operation.

[0081] It should be noted that the inlet / outlet 223 on the guide rail 22 can be formed by openings on the side of the guide rail 22, or the vertical section 222 of the guide rail 22 can be divided into multiple segments, with the inlet / outlet 223 formed by the gap between two adjacent vertical segments 222, or it can be formed by a notch at the lower end of a vertical segment 222. For example, in one embodiment, each vertical segment 222 of the guide rail 22 includes an upper vertical segment 222a and a lower vertical segment 222b, with the inlet / outlet 223 located at the lower end of the upper vertical segment 222a and the switching segment 221 located at the lower end of the lower vertical segment 222b. That is, when the door 30 moves between the open and closed positions, the upper guide wheel 311 rolls within the upper vertical segment 222a, and the lower guide wheel 312 rolls within the lower vertical segment 222b and the switching segment 221.

[0082] Furthermore, the upper vertical section 222a and the lower vertical section 222b can extend in alignment along a straight line, or they can extend in a staggered manner, depending on the internal structure of the fuselage 20 during assembly. The upper vertical section 222a and the lower vertical section 222b can also be formed in various ways. For example, they can be formed by creating vertical guide slots on the left side plate 291 and the right side plate 292 of the fuselage 20, or they can be formed by straight sheet metal strips with guide slot structures installed inside the fuselage 20. Alternatively, considering factors such as production cost, assembly efficiency, and equipment size, the lower vertical section 222b can be formed by slotting the left side plate 291 and the right side plate 292 of the fuselage 20, while the upper vertical section 222a can be formed by straight sheet metal strips. The specific forming method can be designed according to actual conditions and needs, and will not be limited in detail here.

[0083] For a structure where the upper guide wheel 311 is located outside the guide rail 22 when the door 30 is in the closed position, the movement of the upper end of the door 30 towards the inside of the body 20, as well as the lifting and lowering movement of the door 30, can be driven manually by the user, or by drive components such as motors, electric cylinders, and hydraulic cylinders installed inside the body 20 to drive the door 30. For example, in some embodiments, the upper end of the door 30 can be pushed directly towards the inside of the body 20 by the user until the upper guide wheel 311 reaches the inlet / outlet 223 of the guide rail 22. The user can then push the door 30 upwards using friction, a handle, etc., to open the door 30. The door 30 can be closed by the user pulling it back, or it can close automatically by gravity.

[0084] For example, in another embodiment, such as Figures 6 to 11 As shown, to improve the automation level of the door opening and closing 30, the air conditioner 10 also includes a push-pull assembly 40. The push-pull assembly 40 is positioned at the upper end of the door opening and closing 30 when it is in the closed position, and is used to pull the upper guide wheel 311 in and out of the guide rail 22. The push-pull assembly 40 is installed inside the body 20 and located at the upper end of the accommodating cavity 21, so as to be opposite to the upper end of the door opening and closing 30. The push-pull assembly 40 can be composed of a motor, electric cylinder, pneumatic cylinder, hydraulic cylinder, or other driving component capable of pushing and pulling, along with some connecting parts. The connecting parts are used to connect to the upper end of the door opening and closing 30 or the upper guide wheel 311. Then, under the drive of the driving component, the upper end of the door opening and closing 30 is pulled inward toward the body 20 so that the upper guide wheel 311 enters the guide rail 22; or the upper end of the door opening and closing 30 is pushed outward toward the body 20 so that the upper guide wheel 311 disengages from the guide rail 22.

[0085] It is understandable that using the push-pull assembly 40 to push and pull the door 30 makes opening and closing the door 30 more convenient and faster, improving the user experience. Furthermore, the specific structure of the push-pull assembly 40 can be designed according to needs, requiring only that it can push and pull the upper part of the door 30.

[0086] For example, in one embodiment, such as Figure 11 As shown, the push-pull assembly 40 includes a push-pull motor 41, a push-pull gear 42 connected to the push-pull motor 41, a push-pull rack 43 meshing with the push-pull gear 42, and a push-pull member 44 fixed relative to the push-pull gear 42 or the push-pull rack 43; the push-pull rack 43 extends parallel to the movement direction of the upper guide wheel 311 when it enters and exits the inlet and outlet 223, that is, it extends in the front-back direction; the push-pull member 44 is connected to the switch door 30, which can be a sliding connection or a detachable connection.

[0087] Specifically, in this embodiment, taking the side where the front panel 28 of the air conditioner 10 is located as the front side, and the entrance / exit 211 of the accommodating cavity 21 facing the front opening as an example, the upper guide wheel 311 of the switch door 30 moves in and out of the entrance / exit 223 of the guide rail 22 in the front-back direction. The push-pull rack 43 also extends in the front-back direction, ensuring that the push-pull gear 42 and the push-pull rack 43 move relative to each other in the front-back direction, thereby driving the push-pull member 44 to push and pull the upper end of the switch door 30 in the front-back direction, so that the upper guide wheel 311 of the switch door 30 can smoothly move in and out of the guide rail 22.

[0088] It should be noted that in some other embodiments, the entire push-pull assembly 40 can rotate relative to the body 20, and after rotating at a certain angle, the push-pull rack 43 does not extend in the front-back direction. Therefore, the phrase "the push-pull rack 43 extends in the front-back direction" specifically refers to the push-pull assembly 40 being in the state of pushing and pulling the door 30, where the push-pull rack 43 extends in the front-back direction, that is, along the direction of movement when the upper guide wheel 311 of the door 30 enters and exits the inlet and outlet 223 of the guide rail 22. For example, in this embodiment, the push-pull assembly 40 is in a horizontal state when pushing and pulling the door 30, at which time the push-pull rack 43 extends horizontally in the front-back direction.

[0089] The push-pull component 44 can be fixed relative to the push-pull rack 43 or the push-pull gear 42. For example, in some embodiments, the push-pull rack 43 is fixed relative to the body 20 in the front-back direction, while the push-pull gear 42 and the push-pull motor 41 can move back and forth relative to the body 20. In this case, the push-pull component 44 can be fixed relative to the push-pull gear 42 or the push-pull motor 41, for example, by fixing the push-pull component 44 to the housing of the push-pull gear 42 or the push-pull motor 41, the mounting base, etc.

[0090] In this embodiment, to avoid the push-pull component 44 affecting the lifting and lowering movement of the switch door 30, the push-pull component 44 is slidably connected to or detachably connected to the switch door 30. Specifically, the push-pull component 44 can be slidably connected to the switch door 30. In this case, a guide groove 32 can be provided on the switch door 30. The guide groove 32 extends along the lifting and lowering direction of the switch door 30 (i.e., the length direction of the switch door 30), and the two groove walls of the guide groove 32 are spaced apart along the front-back direction of the body 20. The push-pull component 44 extends into the guide groove 32 and is located between the two groove walls of the guide groove 32. Thus, the push-pull component 44 can pull the upper end of the switch door 30 backward or forward by abutting against the groove wall of the guide groove 32, without affecting the up-and-down sliding of the switch door 30.

[0091] Of course, the push-pull component 44 can also be detachably connected to the switch door 30, for example, by gripping, magnetic attraction, or snap-fitting. Specifically, taking the push-pull component 44 as a magnetic attraction component as an example, when it is necessary to pull the upper guide wheel 311 of the switch door 30 into the guide rail 22, the magnetic attraction component first moves towards the switch door 30 until it is magnetically connected to the switch door 30. Then, the upper end of the switch door 30 is pulled towards the inside of the body 20 by magnetic attraction until the upper guide wheel 311 moves to the inlet / outlet 223 of the guide rail 22. When the switch door 30 is driven to move upward, the magnetic attraction component disconnects from the switch door 30 to avoid affecting the lifting and lowering of the switch door 30. When the push-pull component 44 is detachably connected to the switch door 30 by gripping, snap-fitting, or other methods, the specific structure can refer to the above-mentioned magnetic structure, or it can be designed according to the actual situation.

[0092] In one embodiment, please refer to Figure 9 , Figure 12 and Figure 13 To simplify the action of the push-pull assembly 40 when pushing and pulling the door 30, the surface of the door 30 facing the push-pull assembly 40 is provided with a guide groove 32. The guide groove 32 extends along the lifting direction of the door 30, and its two groove surfaces are arranged opposite each other in the front-back direction. The push-pull member 44 is a guide pulley 441, which is slidably installed in the guide groove 32. That is, the push-pull member 44 is slidably connected to the door 30, so the push-pull member 44 can remain connected to the door 30 without the need for connection and release actions, thus simplifying the push-pull action of the push-pull assembly 40.

[0093] And it is understandable, such as Figure 17As shown, when the upper end of the opening / closing door 30 is pulled inward toward the body 20, the lower end of the opening / closing door 30 and the lower guide wheel 312 remain almost stationary in the front-to-back position, and the opening / closing door 30 is in an inclined state. Therefore, when the push-pull component 44 is a guide pulley 441, it can rotate relative to the guide groove 32 during the tilting process of the opening / closing door 30, avoiding jamming. In addition, when the push-pull component 44 is a guide pulley 441, it can also rotate relative to the guide groove 32 during the lifting and lowering movement of the opening / closing door 30, which not only reduces friction with the opening / closing door 30, but also provides better guidance for the lifting and lowering movement of the opening / closing door 30.

[0094] Multiple guide pulleys 441 and guide grooves 32 can be provided to ensure the force balance and movement stability of the door 30 when it is pushed or pulled. For example, in this embodiment, there are two guide grooves 32 with their openings facing each other. The push-pull assembly 40 is provided with at least two guide pulleys 441 corresponding to each guide groove 32, so that the door 30 can be pushed, pulled and guided by the guide pulleys 441.

[0095] In one embodiment, the guide groove 32 has a slot 321 into which the guide pulley 441 extends. The opening direction of the slot 321 is parallel to the surface of the switch door 30. The guide pulley 441 is located between two groove walls of the guide groove 32 and rolls against the groove walls of the guide groove. Specifically, in this embodiment, please refer to... Figure 12 and Figure 13 There are two guide rails 32, with their openings 321 facing each other. One opening 321 is parallel to the surface of the door 30 and faces to the left, while the other opening 321 is parallel to the surface of the door 30 and faces to the right. The two walls of each guide rail 32 are spaced apart in the front-to-back direction. Guide pulleys 441 extend into the guide rails 32 and roll against the side walls of the guide rails 32. This allows the door 30 to be pushed and pulled by the guide pulleys 441 against the walls of the guide rails 32, while avoiding interference with the door 30's lifting and lowering movement.

[0096] In one embodiment, such as Figures 6 to 13 As shown, to fully automate the opening and closing of the door 30, the air conditioner 10 also includes a lifting assembly 50, which drives the door 30 to move up and down. For example, based on the above embodiment, when the upper guide wheel 311 of the door 30 is pulled to the inlet / outlet 223 of the guide rail 22 and can enter the guide rail 22 and roll at any time, the lifting assembly 50 can be activated and drive the door to move up and down, thereby opening and closing the door 30.

[0097] The lifting assembly 50 can be formed in various ways. For example, the lifting assembly 50 includes a lifting motor, a toothed guide rail inside the body 20, a lifting gear installed on the door 30, the lifting motor is connected to the lifting gear and drives the lifting gear to roll in the toothed guide rail, and at this time the lifting motor moves up and down together with the door 30.

[0098] For example, the lifting assembly 50 can consist of a lifting motor and a lifting rope. The lifting rope is connected to the opening and closing door 30, and the opening and closing door 30 can be raised and lowered like a lifting curtain through the cooperation of the lifting motor and the lifting rope.

[0099] For example, to ensure the stability of the door 30 during its lifting and lowering motion, and to simplify the manufacturing process of the air conditioner 10, in one embodiment, such as Figure 11 As shown, the lifting assembly 50 includes a lifting motor 51, a lifting gear 52 connected to the lifting motor 51, and a lifting rack 53 meshing with the lifting gear 52. The lifting rack 53 extends along the lifting direction of the opening and closing door 30 and is fixed to the opening and closing door 30. Specifically, in this embodiment, the lifting motor 51 and the lifting gear 52 are installed inside the body 20 of the air conditioner 10. The output shaft of the lifting motor 51 can be directly connected to the lifting gear 52 or connected to an intermediate transmission gear 54, which then meshes with the lifting gear 52. To protect the lifting gear 52, a gear cover 55 can be fitted over it. The shaft of the lifting gear 52 is supported on the gear cover 55 by bearings and at least partially protrudes outside the gear cover 55 to mesh with the lifting rack 53 on the opening and closing door 30.

[0100] Multiple lifting gears 52 and lifting racks 53 can be provided to improve the stability of the door 30 during lifting and lowering movements. For example, in this embodiment, the air conditioner 10 is also installed in a left-right direction, and the left-right, front-back, and up-down directions of the air conditioner 10 can form a spatial rectangular coordinate system. Two lifting gears 52 and two lifting racks 53 are provided, and the two lifting gears 52 and two lifting racks 53 are spaced apart along the left-right direction of the air conditioner 10. The rotation axis of the two lifting gears 52 extends along the front-back direction, and the two lifting racks 53 are located between the two lifting gears 52. One lifting rack 53 faces the lifting gear 52 on its left and meshes with the lifting gear 52 on its left, while the other lifting rack 53 faces the lifting gear 52 on its right and meshes with the lifting gear 52 on its right.

[0101] Understandably, this design not only improves the stability of the door 30 during its lifting and lowering motion, but also prevents the entire air conditioner 10 from becoming too large.

[0102] In one embodiment, please refer to Figures 6 to 11 To ensure that the lifting rack 53 and lifting gear 52 can still mesh well when the door 30 is tilted during opening and closing, the air conditioner 10 also includes a mounting assembly 60, on which both the push-pull assembly 40 and the lifting assembly 50 are mounted. The mounting assembly 60 is rotatably mounted inside the unit body 20, and the axis of rotation of the mounting assembly 60 is perpendicular to both the extension direction of the push-pull rack 43 and the extension direction of the lifting rack 53. That is, the push-pull rack 43 extends along the front-rear direction of the air conditioner 10, the lifting rack 53 extends along the vertical direction of the air conditioner 10, and the axis of rotation of the mounting assembly 60 extends along the left-right direction of the air conditioner 10.

[0103] It is understandable that when the push-pull assembly 40 pulls the upper end of the switch door 30 toward the inside of the body 20, the entire switch door 30 will tilt at a certain angle. The guide slide 32 and the lifting rack 53 on the switch door 30 will also tilt accordingly. Since the mounting assembly 60 can rotate around its rotation axis, during the tilting process, the switch door 30 will drive the mounting assembly 60 to rotate adaptively through the connection between the guide slide 32 and the guide pulley 441 (i.e., the push-pull component 44) and the connection between the lifting rack 53 and the lifting gear 52, so that the lifting rack 53 and the lifting gear 52 can maintain a good meshing state.

[0104] As for the structure of the mounting component 60, it can be designed according to needs during actual design. It only needs to be able to install the push-pull component 40 and the lifting component 50, and be able to rotatably connect with the body 20 of the air conditioner 10. For example, in one embodiment, such as... Figure 11 As shown, the mounting assembly 60 includes a mounting frame 61 and a mounting block 62. The mounting frame 61 has a hollow structure and is rotatably connected to the body 20. The mounting block 62 is slidably mounted inside the mounting frame 61. The push-pull motor 41, the push-pull gear 42, the push-pull component 44, and the lifting assembly 50 are all mounted on the mounting block 62. The push-pull rack 43 is fixed on the mounting frame 61.

[0105] Specifically, in this embodiment, the mounting frame 61 consists of an upper plate 611, a lower plate 612, and two connecting blocks 613 connecting the upper plate 611 and the lower plate 612. At least one of the upper plate 611 and the lower plate 612 has a semi-enclosed structure, so that after assembly, a space is formed for installing the mounting block 62. The two connecting blocks 613 are connected between the upper plate 611 and the lower plate 612 and are spaced apart along the left-right direction of the air conditioner 10. The upper plate 611 and the lower plate 612 are respectively connected to the connecting frame by screws, thereby enclosing a frame structure. Each connecting block 613 is provided with a pivot 614, and is rotatably connected to the unit body 20 through the pivot.

[0106] The mounting block 62 is slidably installed inside the mounting frame 61. The mounting frame is equipped with the lifting assembly 50 and the push-pull motor 41, push-pull gear 42, and push-pull component 44 of the push-pull assembly 40. The push-pull rack 43 is fixed to the inner wall of the mounting frame 61. When the push-pull gear 42 rotates and moves relative to the push-pull rack 43, the entire mounting block 62 will also slide relative to the mounting frame 61. The push-pull component 44 installed on the mounting block 62 then moves back and forth and pushes and pulls the upper end of the door 30 to open and close.

[0107] To ensure the stable sliding of the mounting block 62, the inner wall of the mounting frame 61 can also be provided with a slide rail, on which the mounting block 62 is slidably mounted. For example, in this embodiment, the upper plate 611 and the two connecting blocks 613 in the mounting frame 61 are provided with slide rails, and the lower plate 612 is fixed with a push-pull rack 43. That is, the four sides of the mounting block 62 have a sliding guide structure, thus ensuring the sliding stability of the slider.

[0108] In one embodiment, please refer to Figure 7 , Figure 11 and Figure 13 The mounting component 60 is positioned corresponding to the upper end of the switch door 30 when it is in the closed position. At least two support bearings 63 are also mounted on the mounting block 62. The at least two support bearings 63 roll against the surface of the switch door 30 facing the mounting component 60.

[0109] Specifically, in this embodiment, a bearing seat 64 is also installed on the surface of the mounting block 62 facing the door 30, and a support bearing 63 is rotatably mounted on the bearing seat 64 and rolls against the door 30. It is understood that the door 30 will tilt during its back-and-forth movement between the open and closed positions. When the door 30 tilts, relative movement can easily occur between the lifting rack 53 and the lifting gear 52, affecting the stability of the meshing. Therefore, by providing the support bearing 63, the door 30 can be stably supported when tilted, preventing the door 30 from moving relative to the lifting gear along with the lifting rack 53. Furthermore, the support bearing 63 can rotate relative to the surface of the door 30 and maintain a tangential state with the surface of the door 30, thus ensuring the relative position of the lifting rack 53 and the lifting gear 52 when the door 30 tilts.

[0110] In addition, multiple support bearings 63 can be provided, such as two, four, six, eight, etc. These multiple support bearings 63 can be arranged at intervals along the length of the opening / closing door 30, or along the width of the opening / closing door 30.

[0111] In one embodiment, such as Figure 12 and Figure 13 As shown, the rotation axis of the lifting gear 52 extends parallel to the extension direction of the push-pull rack 43. The switch door 30 is also provided with a rack limiting groove 33 with its opening facing the lifting gear 52. The lifting rack 53 is formed in the rack limiting groove 33. The teeth of the lifting gear 52 extend into the rack limiting groove 33 and mesh with the lifting rack 53. Taking the air conditioner 10 as an example, in this embodiment, the rotation axis of the lifting gear 52 extends along the front-rear direction of the air conditioner 10, and the opening of the rack limiting groove 33 faces left or right (the specific orientation is determined by the positional relationship between the lifting rack 53 and the lifting gear 52). That is, the teeth of the lifting gear 52 extend into the rack limiting groove 33 in the left and right direction and mesh with the lifting rack 53. Thus, when the push-pull assembly 40 pushes and pulls the door 30 in the front and back direction, it can prevent the lifting gear 52 and the lifting rack 53 from disengaging from each other, ensuring that the lifting gear 52 and the lifting rack 53 always maintain a good meshing state.

[0112] In one embodiment, such as Figure 1As shown, when the switch door 30 moves to the closed position, the surface of the switch door 30 is flush with the outer surface of the body 20. Specifically, in this embodiment, the inlet 211 of the accommodating cavity 21 is a rectangular opening, which is vertically opposite to the flat plate 281 in the front panel 28, and the surface of the flat plate 281 is flat. The switch door 30 is a rectangular plate structure, and its size is adapted to the inlet 211 of the accommodating cavity 21. When the switch door 30 is in the closed position, the four edges of the switch door 30 are exactly parallel and opposite to the four edges of the inlet 211, thus closing the inlet 211. Furthermore, the outer surface of the switch door 30 is flush with the outer surface of the body 20, specifically with the surface of the flat plate 281. This avoids the formation of a large step between the switch door 30 and the outer surface of the body 20 when the switch door is closed, improving the appearance of the air conditioner 10.

[0113] It should be noted that "flush" can mean that the surface of the door 30 and the surface of the flat panel 281 are in the same plane, or it can mean that there is a misalignment error of 2 mm to 5 mm.

[0114] In one embodiment, please refer to Figure 6 and Figure 14 The edge of the switch door 30 is also provided with a limiting structure 34. When the switch door 30 moves to the closed position, the limiting structure 34 abuts against the inner side of the body 20. The limiting structure 34 can be a limiting piece, a limiting block, a limiting strip, etc. The limiting structure 34 can be located at the upper end of the switch door 30, and a corresponding positioning structure can be provided on the inner side of the body 20 at the position corresponding to the limiting structure 34, such as a limiting beam 271 at the lower end of the air outlet frame 27. When the switch door 30 moves to the closed position, the limiting structure 34 abuts against the limiting beam 271. This arrangement not only effectively positions the switch door 30 at its closed position but also prevents the edge of the switch door 30 from deforming and protruding outwards, thus avoiding a step formation with the outer surface of the body 20.

[0115] It is understandable that in the above embodiments, because the door 30 needs to move to the inside of the body 20, specifically to the inside of the front panel 28, when it opens, the width of the door 30 must be at least smaller than the width of the front panel 28 to allow for smooth lifting and lowering. Since the entrance / exit 211 of the accommodating cavity 21 is adapted to the door 30, and given that the width of the sub-machine 100 is greater than the width of the door 30, it is not convenient to increase the width of the door 30 in order to allow it to move smoothly to the inside of the body 20 when opened. Therefore, in one embodiment, please refer to... Figure 4 and Figure 20The air conditioner 10 also includes a clearance door 70, a portion of the edge of which forms a portion of the edge of the entrance 211. The clearance door 70 is also slidably connected to the body 20 so as to change the size of the entrance 211 by sliding.

[0116] Specifically, in this embodiment, two clearance doors 70 are provided, which are respectively located on both sides of the entrance / exit 211 in the width direction. The two edges of the two clearance doors 70 near the entrance / exit 211 respectively constitute the two edges of the entrance / exit 211 in the width direction. Furthermore, the clearance doors 70 are slidably mounted on the body 20, thereby increasing the size of the entrance / exit 211 by sliding the clearance doors 70, ensuring that the submachine 100 can smoothly enter and exit the receiving cavity 21.

[0117] Taking the sub-unit 100 exiting the accommodating cavity 21 as an example, the air conditioner 10 can first drive the opening and closing door 30 upward to the inside of the unit body 20 through the push-pull assembly 40 and the lifting assembly 50, while simultaneously causing the two clearance doors 70 to slide relative to the unit body 20 until the inlet and outlet 211 of the accommodating cavity 21 is large enough for the sub-unit 100 to exit. When the sub-unit 100 needs to return from outside the unit body 20 to the accommodating cavity 21, the reverse operation can be performed.

[0118] It should be noted that, to avoid the obstacle gate 70 occupying too much space when sliding, the obstacle gate 70 can have a certain curvature, and moves in an arc along the outer surface of the body 20 during sliding. Similarly, the obstacle gate 70 can be driven manually by the user, or it can be driven by a motor, electric cylinder, pneumatic cylinder, or other driving components. For example, in one embodiment, as... Figure 20 and Figure 21 As shown, the air conditioner 10 also includes a sliding assembly 80, which drives the bypass door 70 to slide relative to the unit body 20. The sliding assembly 80 can be composed of a motor, cylinder, or other driving components and connecting parts. The connecting parts are connected to the bypass door 70 and drive the bypass door 70 to slide under the drive of the driving components. Alternatively, the sliding assembly 80 itself can be slidable, and the entire bypass door 70 is supported by the sliding assembly 80, which then drives the bypass door 70 to slide. The specific configuration can be set according to the actual situation.

[0119] For example, in one embodiment, such as Figure 22As shown, the sliding assembly 80 includes a sliding motor 81, a sliding gear 82 connected to the sliding motor 81, and a sliding rack 83 meshing with the sliding gear 82. The sliding motor 81 and the sliding gear 82 are both fixed to the body 20. The sliding rack 83 has an arc-shaped structure and is fixed to the clearance door 70. When the sliding motor 81 drives the sliding gear 82 to rotate, the sliding rack 83 and the clearance door 70 move relative to the sliding gear 82, that is, the clearance door 70 moves relative to the body 20, thereby increasing the size of the entrance / exit 211 of the accommodating cavity 21.

[0120] In this embodiment, please refer to Figure 5 , Figures 20 to 22 The body 20 includes a left side plate 291 and a right side plate 292, which respectively form part of the cavity wall of the receiving cavity 21 and are located on the left and right sides of the receiving cavity 21. The sliding motor 81, the sliding gear 82, and the sliding base 84 supporting the sliding motor 81 and the sliding gear 82 are mounted on the surfaces of the left side plate 291 and the right side plate 292 facing away from the receiving cavity 21. An arc-shaped slide rail 841 is provided on the sliding base 84. An arc-shaped sliding rack 83 is fixed to the surface of the avoidance door 70 facing the left side plate 291 or the right side plate 292 and is slidably mounted within the arc-shaped slide rail 841 of the sliding base 84, thereby achieving the sliding installation of the avoidance door 70 on the body 20.

[0121] Furthermore, through the arc-shaped slide rail 841 and the arc-shaped sliding rack 83, the bypass door 70 can move in an arc along the outer wall of the unit 20, thus avoiding the situation where the sliding of the bypass door 70 would require the air conditioner 10 to occupy a large installation space.

[0122] The sliding component 80 can be provided in multiple sets, such as two, three, or four sets on each obstacle gate 70. Multiple sets of sliding components 80 can be arranged at intervals along the length of the obstacle gate 70, which can improve the installation stability and movement stability of the obstacle gate 70.

[0123] In one embodiment, please refer to the figure. Figure 2 and Figure 5The cavity wall of the receiving cavity 21 is also provided with guide rollers 90, which are used to guide the sub-machine 100 when it enters the receiving cavity 21. Specifically, the guide rollers 90 can be casters or rollers whose rotation axis extends parallel to the extension direction of the lifting rack 53. Multiple guide rollers 90 can be provided, and these multiple guide rollers 90 can be arranged at intervals along the depth direction of the receiving cavity 21. It is understood that when the sub-machine 100 enters the receiving cavity 21 from outside the machine body 20, its entry position may deviate, which may lead to friction or jamming between the side of the sub-machine 100 and the inner surface of the receiving cavity 21. Therefore, by providing guide rollers 90 on the cavity wall of the receiving cavity 21, the sub-machine 100 can be guided when its entry position deviates, ensuring that the sub-machine 100 is smoothly received into the receiving cavity 21.

[0124] In one embodiment, the home appliance 10 further includes a sub-unit 100, which is detachably housed within the receiving cavity 21 of the home appliance 10.

[0125] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
