[0061] As shown in Figure 3 , the two first side plates 310 are vertically arranged opposite to each other, and the edges of the two first side plates 310 are outwardly bent to form a folded edge guide rail 3101 for sliding connection with the guide groove 7 of the shell 2 of the air conditioner. In this way, the air duct connecting mechanism can be conveniently and quickly assembled on the air inlet of the air conditioner.

[0062] Optionally, in Figure 21In another embodiment shown, the air duct connection mechanism has a used state and a stored state; the side plates 30 and the main board 10 are separately arranged, and adjacent side plates 30 are detachably connected; when the air duct connection mechanism is in the used state, multiple side plates 30 are spliced ​​to form a ring structure, and the ring structure abuts against the main board 10 to form a box-shaped structure; when the air duct connection mechanism is in the stored state, multiple side plates 30 are disassembled to form a single-piece structure. Compared with the previous embodiment, this embodiment is easier to process, and compared with the previous embodiment, this embodiment is simpler to assemble.

[0063] Optionally, after multiple side plates 30 are spliced ​​to form a ring structure, the main board 10 is installed into the ring structure. One end of the ring structure has a stop to prevent the main board 10 from coming out.

[0064] Optionally, such as Figure 20 As shown, one of the two adjacent side plates 30 has a locking groove 301, and the other has a locking buckle 302. When the air duct connection mechanism is in use, the locking buckle 302 engages with the locking groove 301. In this way, the air duct connection mechanism is locked in the use state by using the locking groove 301 and the locking buckle 302. The structure is simple and the assembly is convenient.

[0065] Optionally, the air duct connection mechanism further includes an annular connection structure 20, which is arranged circumferentially along the first air inlet 11 and is used to connect with the air inlet pipe 1.

[0066] Optionally, the annular connection structure 20 has a threaded structure 21 for connection with the air inlet pipe.

[0067] like Figure 2 and Figure 3 As shown, this application also provides a portable air conditioner, which includes: a housing 2 having a second air inlet 3; an air duct connection mechanism 4 detachably mounted on the housing 2 and located at the second air inlet 3, the air duct connection mechanism 4 being one of the air duct connection mechanisms described above or below; and an air inlet pipe 1 connected to the second air inlet 3 via the air duct connection mechanism 4. The portable air conditioner provided in this application has a larger area and higher efficiency for its second air inlet 3.

[0068] Optionally, the cross-section of the annular connecting structure 20 is circular, and the end face of the annular structure formed by the multiple side plates 30 is rectangular.

[0069] like Figure 2 and Figure 3As shown, the portable air conditioner also includes an exhaust duct 5, and the housing 2 also has an exhaust port 6, which is connected to the exhaust duct 5 to exhaust gas outdoors. The portable air conditioner has a single-duct mode and a dual-duct mode. When the portable air conditioner is in single-duct mode, only the exhaust duct 5 is in working condition. When the portable air conditioner is in dual-duct mode, the air duct connecting mechanism and the air inlet duct 1 are installed at the second air inlet 3, and both the exhaust duct 5 and the air inlet duct 1 are in working condition. The cross-sectional area of ​​the second air inlet 3 is larger than the area of ​​the exhaust port 6. The exhaust duct 5 has an outer air outlet 51, and the air inlet duct 1 has an outdoor air inlet 101.

[0070] Optionally, the housing 2 includes a rear plate 200, on which a guide groove is provided.

[0071] Optionally, the folding angle of the side panel 30 can be adjusted according to the size of the second air inlet 3.

[0072] Optionally, two adjacent side panels 30 are connected by a flexible structure, thereby allowing the folding angle of the side panels 30 to be adjusted.

[0073] This application also provides a method for using a portable air conditioner, which converts a single-duct portable air conditioner into a dual-duct portable air conditioner. The outdoor air inlet duct and the outdoor air inlet of the dual-duct portable air conditioner are connected by the aforementioned air duct connection mechanism. The first air inlet 11 of the air duct connection mechanism is connected to the air outlet of the outdoor air inlet duct, and the annular structure formed by the multiple side plates 30 of the air duct connection mechanism is connected to the outdoor air inlet.

[0074] like Figure 1 As shown, in related technologies, the air inlet area is relatively small, which leads to insufficient airflow when using a single duct, affecting the cooling effect. According to a comparative experiment on a certain portable air conditioner, to achieve interchangeability between single and dual ducts, directly reducing the air inlet area reduces the cooling capacity from 3500W to 2950W, a 15.8% decrease; the energy efficiency ratio drops from 2.45 to 2.03, a 17% reduction, severely impacting the cooling effect. Related technologies also achieve a larger air inlet area by adding two components (air inlet grille and air inlet baffle), maintaining the same cooling performance, but reducing the number of units that can be installed in a cabinet from 352 to 311, a 12% reduction, which will have a significant negative impact on the overall transportation cost and competitiveness.

[0075] The dual-duct portable air conditioner provided in this application adds a box-shaped duct connection mechanism outside the grille of the single-duct portable air conditioner, maintaining the same grille size as the original single-duct portable air conditioner, thus ensuring a constant air intake. The interlocking structure of single-wave and double-wave elastic grooves fulfills the functional requirements for folding and storage. The duct connection mechanism in this application is made of high-toughness plastic material, and after machine tool production, its initial state is as follows... Figure 4Because of the existence of the groove structure, the side plate can be conveniently folded inward by the single-wave elastic groove, folded inward by 90 degrees, and formed into a box state structure. At this time, the lock slot and the lock catch on the adjacent two side plates are matched with each other to realize locking, at this time, the air duct connecting mechanism is adjusted by the sheet-shaped part to form a four-around seal, and the box-shaped part is tightly assembled between the folded plates, at this time, it can be used for mounting on the air inlet of the mobile air conditioner. The air duct connecting mechanism is inserted into the guide groove on the mobile air conditioner through the two guide rails, and tight assembly can be realized.

[0076] By folding the first side plate inward by 180 degrees through the single-wave elastic groove, and folding the second side plate outward by 180 degrees through the double-wave elastic groove, a stacked state structure is formed, which is convenient for storage and transportation, and realizes a large reduction in the area of the parts.

[0077] The present application is to meet the four-edge folded plate that can be folded through the groove, and the material thickness of the main body and the groove is specially set.

[0078] The foldable air duct connecting mechanism with the single-wave and double-wave elastic groove matching structure of the present application realizes the interchange of single and double air pipes for a large-area air inlet, and also meets the purpose of small occupied body after folding. The same functional effect can be achieved by simply changing the number and angle of the waveforms.

[0079] Compared with the split embodiment, the folding embodiment has high assembly efficiency and low mold investment cost.

Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0084] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0085] It should be noted that the terms "first", "second", and the like, used in the description and in the claims of the present application as well as above-mentioned drawings, are intended to distinguish similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of data so designated is not meant to limit a given embodiment to a specific embodiment but that the embodiments of the application described herein are well suited to perform the described functions but that they are implemented in other embodiments and configurations than those described. Furthermore, the terms "comprises", "comprising", "includes", "including", and the like, are meant to cover non-exclusive inclusions, such that yet unmentioned elements or methods are also contained in a corresponding apparatus or method that is still within the scope of the present application.

[0086] The preferred embodiments of the application are described above in detail. The application can be modified and changed in various ways by those skilled in the art without departing from the spirit and principles of the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application should be included in the scope of the protection of the application.
