[0033] When the air conditioner is not in use or is being moved, the power plug is separated from the power socket and plugged into the storage socket on the air conditioner. If there are manufacturing errors in the size of the plug prongs and / or the size of the socket holes, the prongs may not be able to be inserted into the socket holes, or the power plug may fall off and detach from the storage socket, thus affecting the storage effect.

[0034] To solve this technical problem, this utility model proposes an air conditioner.

[0035] Please see Figures 1 to 3 In one embodiment of this utility model, the air conditioner includes a power plug 10, a housing 20, and a plug ring 30. The power plug 10 has pins 11. The housing 20 has an insertion hole 22 for inserting the pins 11 when storing the power plug 10. The plug ring 30 is connected to the inner surface of the housing 20, and the plug ring 30 has a clamping hole 31 that engages with the insertion hole 22. At least a portion of the pins 11 are interference-fitted into the clamping hole 31. Thus, the power plug 10 can be reliably fixed on the housing 20, improving the storage effect of the power plug 10 in the air conditioner.

[0036] In the technical solution of this utility model, the housing 20 of the air conditioner is provided with an insertion hole 22, and the inner surface of the housing 20 is also provided with a plug ring 30. The clamping hole 31 of the plug ring 30 is connected to the insertion hole 22. When the air conditioner is idle or being moved, the prongs 11 of the power plug 10 are sequentially inserted into the insertion hole 22 and the clamping hole 31, and at least some of the prongs 11 are interference-fitted with the hole wall of the clamping hole 31, so as to realize the reliable storage of the power plug 10, thereby reliably protecting the power plug 10, reducing the possibility of corrosion of the power plug 10 by water vapor and interference and collision, and improving the service life of the power plug 10.

[0037] Furthermore, the plug ring 30 has a large tolerance due to its elasticity, and different sized plugs 11 can be firmly inserted into the clamping hole 31. That is, the air conditioner can be equipped with power plugs 10 of different sizes according to needs, and power plugs 10 of different sizes can also be stored, improving the practicality of the air conditioner.

[0038] It should be noted that the plug ring 30 is an elastic plug ring 30, which gives the plug ring 30 the ability to deform elastically to facilitate clamping the plug pins 11. The specific material of the plug ring 30 includes, but is not limited to, plastic, rubber, and silicone. The plug ring 30 is integrally formed with the housing 20, or is fixed to the housing 20 as a whole by means of bonding, welding, etc. The power plug 10 can be a two-prong plug or a three-prong plug, and the number and shape of the insertion holes 22 can be adapted to the type of power plug 10. The plug pins 11 are interference-fitted into the clamping holes 31 to meet the purpose of the plug ring 30 clamping the plug pins 11 through the clamping holes 31. At the same time, the elastic deformation of the plug ring 30 facilitates the adaptation of the plug ring 30 to plug pins 11 of different sizes, that is, plug pins 11 within a certain size range will not affect the storage of the power plug 10.

[0039] Please see Figures 2 to 3In an embodiment of this utility model, the end of the plug ring 30 away from the housing 20 is provided with a notch 32. The notch 32 is used to assist the deformation of the clamping hole 31. It can be understood that due to the setting of the notch 32, the hole wall of the clamping hole 31 is divided into multiple elastic cantilever arms. When the elastic cantilever arms are subjected to force, they can use their peripheral space to deform, thereby improving the deformability of the plug ring 30. This allows at least some of the pins 11 to be interference-fitted into the clamping hole 31, that is, the hole wall of the clamping hole 31 clamps the pins 11 and makes zero-gap contact with the outer surface of the pins 11, thereby improving the connection strength between the pins 11 and the plug ring 30, reducing the possibility of the pins 11 coming out, and improving the storage effect of the power plug 10 in the air conditioner.

[0040] Specifically, in the embodiments of this utility model, multiple notches 32 are provided, and each notch 32 is evenly and spaced around the circumference of the clamping hole 31. This arrangement can form multiple elastic cantilevers that are evenly and spaced, which helps to improve the deformability of the insertion ring 30. At the same time, it reliably and evenly divides the hole wall of the clamping hole 31, which helps to reduce the possibility of partial breakage of elastic cantilevers due to uneven force, and improves the service life of the insertion ring 30. When the number of notches 32 is even, taking two notches 32 as an example, two opposite notches 32 can be obtained by passing through the insertion ring 30 radially along the clamping hole 31 through a through hole. When the number of notches 32 is odd, taking three notches 32 as an example, the included angle between the central axes of two adjacent notches 32 is 120°, and the central axis of each notch 32 passes through the center of the clamping hole 31.

[0041] Optionally, in an embodiment of this utility model, the plug ring 30 includes a connecting section 33 and a clamping section 34. One end of the connecting section 33 is connected to the housing 20, and the other end is connected to the clamping section 34. The notch 32 is formed in the clamping section 34. Thus, by providing the connecting section 33, a larger connection area between the connecting section 33 and the housing 20 can be ensured, improving the connection strength and reliability between the plug ring 30 and the housing 20. Simultaneously, it can increase the contact area between the pin 11 and the plug ring 30 to a certain extent, improving the insertion stability of the power plug 10. It also ensures that the clamping section 34 clamps and fixes the pin 11 through elastic deformation, improving the connection strength between the pin 11 and the clamping section 34, thereby improving the storage effect of the power plug 10 on the housing 20. However, in other embodiments, the plug ring 30 only includes the clamping section 34.

[0042] To ensure the fixing of the connector ring 30 to the pins 11, at least a portion of the pins 11 are interference-fitted into the clamping hole 31, meaning that the outer peripheral surface of at least a portion of the pins 11 is in zero-gap contact with the wall of the clamping hole 31. Therefore, please refer to... Figure 2In this embodiment of the present invention, the diameter of the clamping hole 31 gradually decreases in the direction away from the insertion hole 22, so as to complete the fixing of the plug ring 30 to the plug 11 through interference fit; it can be understood that, because the diameter of the clamping hole 31 gradually decreases in the direction away from the insertion hole 22, the diameter of the head end of the clamping hole 31 connected to the insertion hole 22 is larger than the diameter of the tail end of the clamping hole 31, which facilitates the insertion of the plug 11, and when the plug 11 extends to the clamping hole 31 at the tail end of the plug ring 30, the plug 11 is clamped. During this process, due to the deformable properties of the plug ring 30, the plug ring 30 can adapt to and clamp the plug 11 within a certain size range; while When the clamping hole 31 has a notch 32 in its wall, the diameter of the clamping hole 31 from the connecting section 33 to the clamping section 34 gradually decreases. This allows for clamping of the pin 11 when it extends to the clamping hole 31 at the tail end of the plug ring 30. Furthermore, it can accommodate and clamp pins 11 of different sizes. This is achieved through the deformation of the clamping section 34 under stress, for example, by enlarging the diameter of the clamping hole 31 within the clamping section 34 to be equal to the diameter of any clamping hole 31 within the connecting section 33. In this case, the outer circumferential surface of most of the pins 11 is in zero-gap contact with the wall of the clamping hole 31, thereby reliably improving the practicality of the plug ring 30 and enhancing the storage reliability of the power plug 10. However, in other embodiments, the clamping hole 31 is provided with a constant diameter in its axial direction.

[0043] Please see Figure 2 In this embodiment of the invention, the diameter of the insertion hole 22 gradually decreases towards the clamping hole 31. This allows the wall of the insertion hole 22 to form a guide slope inclined towards its centerline, smoothly aligning with the wall of the clamping hole 31. Consequently, when the plug 11 approaches the insertion hole 22, the guide slope guides the plug 11 to quickly pass through the insertion hole 22 and extend into the clamping hole 31, improving the storage efficiency of the power plug 10. However, in other embodiments, the insertion hole 22 is provided with a uniform diameter along its axial direction.

[0044] For easier machining of the insertion ring 30 into the housing 20, please refer to [link / reference]. Figures 2 to 3 In an embodiment of this utility model, the inner surface of the housing 20 is provided with an outwardly recessed portion 23, and the insertion ring 30 is connected to the bottom wall of the recessed portion 23. On the one hand, this can shorten the length of the insertion ring 30 protruding from the inner surface of the housing 20, reduce the space occupied by the insertion ring 30, and at the same time reduce the possibility of interference between the insertion ring 30 and other components inside the housing 20. It can also extend the overall length of the insertion ring 30 with the same protrusion length, which helps to improve the deformability of the insertion ring 30 and increase the effective connection area between the insertion ring 30 and the pin 11, thereby improving the connection strength between the pin 11 and the insertion ring 30. On the other hand, the recessed portion 23 can serve as a positioning reference, making it convenient for the insertion ring 30 to be quickly formed on the inner surface of the housing 20, thus improving processing efficiency.

[0045] For easier storage of the power plug 10, please refer to [link / reference needed]. Figures 1 to 2 In this embodiment of the invention, the outer surface of the housing 20 has an outwardly protruding storage platform 24, and the insertion hole 22 penetrates the storage platform 24. That is, one end of the storage platform 24 is connected to the outer surface of the housing 20, and the other end extends away from the housing 20. This arrangement helps to strengthen the structural strength of the housing 20 and reduces the risk of deformation caused by factors such as plugging and unplugging the power plug 10 or the recessed portion 23. Furthermore, the storage platform 24 can indicate the storage location, conveying the location information of the power plug 10 on the housing 20 when it is necessary to store it. This facilitates the user in quickly finding the storage location of the power plug 10 and inserting the pins 11 into the clamping hole 31 at that location, improving storage convenience. However, in other embodiments, the housing 20 has a label indicating the storage location of the power plug 10.

[0046] Furthermore, in an embodiment of this utility model, the storage platform 24 is provided with a limiting rib 25 on the side opposite to the insertion ring 30. The limiting rib 25 extends along the edge of the storage platform 24. At this time, the limiting rib 25 and the storage platform 24 enclose a storage groove with the opening facing outward. Thus, after the plug 11 of the power plug 10 enters the storage groove, the limiting rib 25 restricts the movement range of the plug 11 on the storage platform 24, which helps to speed up the plug 11 to quickly find and align with the insertion hole 22, improving the insertion efficiency. It can also effectively block the connection between the power plug 10 and the storage platform 24, reducing the risk of foreign objects falling into the connection between the power plug 10 and the storage platform 24 and causing safety hazards, and improving the service life of the air conditioner.

[0047] Optionally, in an embodiment of the present invention, the housing 20 includes a rear panel 21, and the insertion hole 22 is formed in the rear panel 21. When the rear panel 21 includes a rear main body plate and two side plates disposed on opposite sides of the rear main body plate, as shown... Figure 1 As shown, the insertion hole 22 is provided on the rear main body plate, or the insertion hole 22 may also be provided on the side plate. Of course, in other embodiments, the housing 20 includes a front panel, and the front panel has a side plate connected to the rear panel 21, and the insertion hole 22 may also be provided on the side plate of the front panel.

[0048] Optionally, in an embodiment of this utility model, the air conditioner includes an indoor unit and an outdoor unit. The indoor unit includes the aforementioned power plug 10, housing 20, and connector ring 30. The indoor unit and the outdoor unit are connected by a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant. Specifically, the air conditioner of this utility model can be a split-type air conditioner that is easy for users to install themselves. It uses a refrigerant hose assembly to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and refrigerant is injected into the refrigerant circuit before the equipment leaves the factory. In this way, when users install the equipment themselves, they only need to fix the indoor unit and the outdoor unit separately, without assembling the refrigerant pipe and adding refrigerant, thereby reducing the installation difficulty and realizing user-installed installation. However, this design is not limited to this. In other embodiments, the air conditioner of this utility model can also be a common split-type air conditioner.

[0049] Optionally, in an embodiment of this utility model, the compressor of the air conditioner is located in the indoor unit, which can reduce the weight of the outdoor unit and facilitate the installation of the outdoor unit; correspondingly, the compressor is also equipped with a noise reduction structure to ensure low-noise operation of the indoor unit.

[0050] Optionally, in an embodiment of this utility model, the bottom of the indoor unit is provided with casters to facilitate the movement and transport of the indoor unit; correspondingly, the indoor unit is provided with a locking structure to constrain the rotation of the casters, ensuring stable operation of the indoor unit.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
