Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a sealing plate assembly and a mobile air conditioner. Background Art

[0002] A mobile air conditioner is a portable air conditioning device that integrates the compressor, evaporator, condenser and other components into a mobile device, and discharges the heat generated during the refrigeration process of the mobile air conditioner to the outside through an exhaust duct to maintain the indoor cooling effect. For the setting of the air duct, a sealing plate is generally set on the window frame, and the sealing plate has a mounting hole. One end of the air duct is connected to the mounting hole so that the heat can be discharged from the room through the air duct.

[0003] In the related art, there are two sealing plates, which are slidably matched, and a mounting hole is opened on one of the sealing plates. When the mobile air conditioner needs to be used, the two sealing plates are installed on the window frame. At this time, the mounting hole connects the air outlet of the air duct to the outdoors; when the mobile air conditioner is idle, the two sealing plates are removed from the window frame, and the two sealing plates slide relative to each other so that the other sealing plate closes the mounting hole to reduce dust from entering the air duct.

[0004] However, there is no fixed structure between the two sealing plates in the related art, and there is a gap between the two sealing plates, and the connection is not tight enough. As a result, when the sealing plates are installed vertically, the two sealing plates are prone to relative sliding due to their own gravity, and the user needs to manually maintain the relative position of the two sealing plates for installation, resulting in a poor user experience.

Figure 1-7 This application is described in further detail.

[0032] Reference Figure 1 and Figure 2 The embodiment of the first aspect of the utility model provides a sealing plate assembly, which is installed on the window frame to replace the window to block the indoor and outdoor. Specifically, the sealing plate assembly includes a first sealing plate 100 and a second sealing plate 200, the first sealing plate 100 and the second sealing plate 200 are slidably matched, and the second sealing plate 200 is slidably connected to the first sealing plate 100 along the first direction. In this embodiment, referring to Figure 1 , the first direction is the length direction of the second sealing plate 200 .

[0033] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The first sealing plate 100 is provided with an installation hole 110 for installing the air duct 310. The installation hole 110 is provided on one side of the first sealing plate 100. The second sealing plate 200 can slide relative to the first sealing plate 100 to close or open the installation hole 110. When the installation hole needs to be closed, the second sealing plate 200 slides with the first sealing plate 100 from the side of the first sealing plate 100 away from the installation hole 110, and slides toward the side of the first sealing plate 100 close to the installation hole 110, until the first sealing plate 100 and the second sealing plate 200 are completely overlapped, and the second sealing plate 200 completely covers the installation hole 110, thereby achieving the closure of the installation hole 110.

[0034] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The first sealing plate 100 includes a first plate portion 120 and two first side portions 130. The first plate portion 120 is arranged along a first direction, and the two first side portions 130 are arranged on both sides of the first plate portion 120 along a second direction, and the second direction is perpendicular to the first direction. The first plate portion 120 and the two first side portions 130 are surrounded to form a slide groove for the second sealing plate 200 to slide, and the second sealing plate 200 slides in cooperation with the slide groove. In this embodiment, refer to Figure 1 and Figure 2 , the second direction is the width direction of the first sealing plate 100 .

[0035] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The second sealing plate 200 includes a second plate portion 210 and two second side portions 220. The second plate portion 210 is arranged along the length direction of the first plate portion 100, and the two second side portions 220 are arranged on both sides of the second plate portion 210 along the second direction. The two second side portions 220 are located between the two first side portions 130. When the mounting hole 110 needs to be closed, the second sealing plate 200 slides relative to the slide groove so that the second side portion 220 slides between the two first side portions 130 to limit the travel range of the first sealing plate 100 relative to the first sealing plate 100 along the second direction, so that the second sealing plate 200 closes the mounting hole 110.

[0036] It is understandable that in some embodiments of the present invention, reference Figure 1 and Figure 2 The first side portion 130 is provided with a limiting portion 131, and the number of the limiting portions 131 is two. The two limiting portions 131 are respectively located on the two first side portions 130 and are arranged opposite to each other. The limiting portion 131 is clearance-matched with the second side portion 220, so that the second side portion 220 can abut against the limiting portion 131 during the sliding process of the second sealing plate 200 relative to the first sealing plate 100, so that the limiting portion 131 limits the travel range of the second sealing plate 200 relative to the first sealing plate 100 along the third direction, and the third direction is perpendicular to the first direction and the second direction at the same time. In this embodiment, refer to Figure 2 , the third direction is the thickness direction of the first sealing plate 100 .

[0037] It is understandable that in some embodiments of the present invention, reference Figure 2 and Figure 3The second sealing plate 200 is provided with a protrusion 230, and the number of the protrusions 230 is two. The two protrusions 230 are respectively arranged at positions of the second plate portion 210 close to the two second side portions 220. The protrusions 230 are located between the first plate portion 120 and the second plate portion 210. The protrusions 230 are arranged along the first direction. One end of the protrusion 230 is fixedly connected to the second plate portion 210, and the other end abuts against the first plate portion 120. The protrusions 230 can reduce the gap between the first plate portion 120 and the second plate portion 210, increase the force between the first plate portion 120 and the second plate portion 210, so that the first sealing plate 100 and the second sealing plate 200 have an interference fit. When the second sealing plate 200 slides relative to the first sealing plate 100, the protrusion 230 is pressed against the first sealing plate 100, and the second side portion 220 is pressed against the limiting portion 131, so that the second sealing plate 200 can be subjected to a greater friction force, thereby making the two fit more closely. Therefore, when the sealing plate assembly is installed vertically, due to the greater friction force between the first sealing plate 100 and the protrusion 230, there is no need to maintain the relative position between the first sealing plate 100 and the second sealing plate 200 by hand, which makes user operation more convenient and thus improves user experience.

[0038] It should be noted that, in some embodiments, the number of the protrusions 230 can also be one, and the protrusion 230 is arranged in the middle of the second plate portion 210 along the first direction, and the protrusion 230 is located between the first plate portion 120 and the second plate portion 210. The protrusion 230 is used to increase the force between the first plate portion 120 and the second plate portion 210, so that when the second sealing plate 200 slides relative to the first sealing plate 100, the first sealing plate 100 and the second sealing plate 200 have an interference fit, so that the second sealing plate 200 can be subjected to greater friction, thereby making the fit between the two closer. When the protrusion 230 is located in the middle of the first plate portion 120 and the second plate portion 210, the deformation of the middle of the first plate portion 120 and the second plate portion 210 is relatively large, and the position of the force acting on the protrusion 230 and the second plate portion 210 is far away from the position of the force acting on the second side portion 220 and the limiting portion 131, thereby increasing the gap between the second plate portion 210 and the first plate portion 120, resulting in poor self-locking performance of the sealing plate assembly. Figure 1 and Figure 2 In the present embodiment, two protrusions 230 are provided, and the two protrusions 230 are respectively arranged at positions of the second plate portion 210 close to the two second side portions 220, so that when the protrusions 230 are squeezed, a force is applied to two positions of the second plate portion 210, so that the force applied to the second plate portion 210 is more dispersed and uniform, and the position of the force between the protrusions 230 and the second plate portion 210 is closer to the position of the force between the second side portion 220 and the limiting portion 131, thereby reducing the deformation of the first plate portion 120 and the second plate portion 210, and improving the self-locking property of the sealing plate assembly.

[0039] It can be understood that, in some embodiments, the second plate portion 210 is provided with a protrusion 230 near the two second side portions 220 and in the middle of the second plate portion 210, thereby increasing the contact area between the protrusion 230 and the first plate portion 120, thereby making the force between the two more balanced and reducing the deformation of the first plate portion 120 caused by the greater force of the protrusion 230 on a certain position of the first plate portion 120.

[0040] In some other embodiments, the protrusion 230 may also be arranged on the first sealing plate 100, and the protrusion 230 is arranged in the middle of the first plate portion 120 along the first direction. When the second sealing plate 200 slides relative to the first sealing plate 100, the first sealing plate 100 and the second sealing plate 200 are interference fit, so that the second sealing plate 200 can be subjected to greater friction, thereby making the two fit more closely. Compared with the arrangement of the present embodiment, the protrusion 230 of this arrangement is arranged along the first direction of the first plate portion 120, but the first plate portion 120 is provided with a mounting hole 110. The arrangement of the mounting hole 110 reduces the length of the protrusion 230 that can be installed. Therefore, when the second sealing plate 200 slides relative to the first sealing plate 100 to cover the mounting hole 110, there is no protrusion 230 between the side of the second plate portion 210 close to the mounting hole 110 and the first plate portion 120, and thus there is no force driving the side of the second plate portion 210 close to the mounting hole 110 and the first plate portion 120 to stick together, which easily leads to a gap between the first sealing plate 100 and the second sealing plate 200, resulting in a poor sealing effect. Referring to FIG. Figure 1 and Figure 2 In this embodiment, the protrusion 230 is arranged on the second sealing plate 200, so that the protrusion 230 can be distributed in the entire stroke range of the second plate portion 210 along the first direction, and then when the second sealing plate 200 slides relative to the first sealing plate 100 to cover the mounting hole 110, a protrusion 230 is also provided between the side of the second plate portion 210 close to the mounting hole 110 and the first plate portion 120, so that the side of the second plate portion 210 close to the mounting hole 110 and the first plate portion 120 are continuously subjected to interaction force, so that the first sealing plate 100 and the second sealing plate 200 can be continuously and tightly fitted, thereby ensuring the sealing effect.

[0041] In some other embodiments, the first plate portion 120 may be provided with protrusions 230 at positions close to the two first side portions 130, or the first plate portion 120 may be provided with protrusions 230 at positions close to the two first side portions 130 and in the middle of the first plate portion 120, thereby further increasing the contact area between the protrusions 230 and the second plate portion 210, further making the force between the two more balanced, and further reducing the deformation of the second plate portion 210 caused by the greater force of the protrusion 230 on a certain position of the second plate portion 210.

[0042] It is understandable that in some other embodiments, the raised portion 230 can also be provided on the second side portion 220, and the raised portion 230 is provided on both second side portions 220, and the raised portion 230 is located between the first side portion 130 and the second side portion 220. The raised portion 230 is used to increase the force between the first side portion 130 and the second side portion 220. When the second sealing plate 200 slides relative to the first sealing plate 100, the second side portion 220 is subjected to a greater friction force, so that the two fit more closely. When the raised portion 230 is located between the first side portion 130 and the second side portion 220, the deformation produced by the two second side portions 220 is smaller, and the closer the second sealing plate 200 is to the mounting hole 110, the more difficult it is to slide, and the problem of jamming is likely to occur, and the operation is more difficult. In the present embodiment, the area of ​​the first sealing plate 100 and the second plate portion 210 is larger, so it is easy to produce a larger deformation. Refer to Figure 1 and Figure 2 The two protrusions 230 are respectively arranged at positions of the second plate portion 210 close to the two second side portions 220. When the protrusions 230 are located between the first plate portion 120 and the second plate portion 210, the protrusions 230 are squeezed to apply a force to the second plate portion 210, thereby causing the first sealing plate 100 and the second plate portion 210 to deform. When the second plate portion 210 is pushed, the gap between the first sealing plate 100 and the second plate portion 210 becomes larger, thereby making it easier to push the second plate portion 210. When the pushing of the second plate portion 210 stops, due to the interference fit of the first sealing plate 100 and the second plate portion 210, the deformation of the first sealing plate 100 and the second plate portion 210 is reduced and they can remain relatively still.

[0043] It is understandable that in some embodiments of the present invention, reference Figure 2 and Figure 3The raised portion 230 is constructed as a rib arranged along the first direction. When the second sealing plate 200 slides relative to the first sealing plate 100, due to the interference fit between the two, there is a greater friction between the rib and the first plate portion 120, which makes the fit between the two closer. Therefore, when the sealing plate assembly is installed vertically, due to the greater friction between the first sealing plate 100 and the rib, there is no need to maintain the relative position between the first sealing plate 100 and the second sealing plate 200 by hand, which makes user operation more convenient and improves user experience.

[0044] In some other embodiments, the raised portion 230 can also be a plurality of protrusions, which are arranged on the second plate portion 210 at intervals along the first direction. The protrusions are located between the first plate portion 120 and the second plate portion 210. The protrusions abut against the first plate portion 120 to increase the contact area between the two, so that the force between the two can be more uniform.

[0045] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 The end surface of the second side portion 220 is provided with a first guide portion 221, and the first guide portion 221 is used to guide the second side portion 220 to move between the limiting portion 131 and the first plate portion 120, so as to reduce the situation where the first sealing plate 100 and the second sealing plate 200 cannot be aligned during assembly, so that the first sealing plate 100 and the second sealing plate 200 can be assembled quickly and conveniently for users to operate. In this embodiment, referring to Figure 5 The first guide portion 221 is a first chamfer, and the first chamfer is arranged along the second direction. When the first sealing plate 100 and the second sealing plate 200 are assembled, the first chamfer abuts against the limiting portion 131, so that the limiting portion 131 slides relative to the first chamfer, so that the second side portion 220 moves between the limiting portion 131 and the first plate portion 120, thereby enabling the first sealing plate 100 and the second sealing plate 200 to be quickly assembled.

[0046] It is understandable that in some embodiments of the present invention, reference Figure 2 and Figure 3 The end surface of the protrusion 230 is provided with a second guide portion 231, and the second guide portion 231 is used to guide the protrusion 230 to move between the first plate portion 120 and the second plate portion 210. In this embodiment, referring to Figure 3 The second guide portion 231 is a second chamfer, and the second chamfer is arranged along the second direction. When the first sealing plate 100 and the second sealing plate 200 are assembled, the second chamfer abuts against the first plate portion 120, and then the second chamfer slides relative to the first plate portion 120. The first sealing plate 100 and the second sealing plate 200 transition from a clearance fit to an interference fit, which is convenient for alignment and assembly and is beneficial to the early sliding, thereby improving the convenience of installation.

[0047] It is understandable that in some embodiments of the present invention, reference Figure 4 , Figure 5 and Figure 6 The end surface of the second side portion 220 is provided with an avoidance portion 2211, the avoidance portion 2211 and the first chamfer are arranged along the first direction, the position of the avoidance portion 2211 and the position of the second guide portion 231 are arranged correspondingly in the second direction, along the first direction, the length of the avoidance portion 2211 corresponds to the length of the second chamfer, and the avoidance portion 2211 is used to make the first chamfer and the second chamfer staggered along the second direction, and refer to Figure 6 , along the third direction, any spacing s1 between the avoidance portion 2211 and the limiting portion 131 is greater than or equal to the maximum spacing s2 between the first chamfer and the limiting portion 131, so that when the first sealing plate 100 and the second sealing plate 200 need to be assembled, the second chamfer first abuts against the first plate portion 120, and the first plate portion 120 corresponds to the position of the avoidance portion 2211. As the second sealing plate 200 slides relative to the first sealing plate 100, the second chamfer slides relative to the first plate portion 120 to drive the second sealing plate to move along the second direction, and the number of overlapping components of the first sealing plate 100 and the second sealing plate 200 along the first direction increases. When the first chamfer abuts against the limiting portion 131, the limiting portion 131 slides relative to the first chamfer, further increasing the interference between the first sealing plate 100 and the second sealing plate 200, the first sealing plate 100 and the second sealing plate 200 achieve interference fit, and the force between the protrusion 230 and the first plate portion 120 increases. When there is no avoidance portion 2211, the first chamfer and the second chamfer are arranged along the second direction. Then, when the first sealing plate 100 and the second sealing plate 200 are assembled, the first chamfer and the second chamfer abut against the first sealing plate at the same time, so that the span of the increase in the interference fit between the first sealing plate 100 and the second sealing plate 200 is relatively large, which makes it inconvenient for users to operate. However, in this embodiment, by distributing the first chamfer and the second chamfer in a staggered manner along the second direction, the chamfers can be guided successively in opposite directions on both sides of the raised portion 230, that is, the gap between the first sealing plate 100 and the second sealing plate 200 is reduced successively on both sides of the raised portion 230 instead of reducing the gap between the first sealing plate 100 and the second sealing plate 200 from both sides at the same time, thereby facilitating user operation and improving assembly efficiency.

[0048] In this embodiment, refer to Figure 6, the avoidance portion 2211 is horizontally arranged along the first direction, that is, the spacing s1 is fixed along the first direction, and the spacing s1 is equal to the spacing s2 at the connection between the avoidance portion 2211 and the first chamfer. In some other embodiments, the end surface of the avoidance portion 2211 close to the limiting portion 131 can also be arranged in a curved surface, that is, the spacing s1 changes along the first direction, and the connection between the avoidance portion 2211 and the first chamfer can also be stepped, that is, staggered along the first direction, so that the spacing s1 is greater than the spacing s2, and then when the second sealing plate 200 slides relative to the first sealing plate 100, the second chamfer slides relative to the first plate portion 120, and the second sealing plate is driven to move along the second direction, the first chamfer can abut against the limiting portion 131, so that the limiting portion 131 slides relative to the first chamfer, further increasing the interference between the first sealing plate 100 and the second sealing plate 200, and the first sealing plate 100 and the second sealing plate 200 achieve interference fit.

[0049] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 The second side portion 220 is provided with a plurality of through holes 222, which are arranged at intervals along the first direction. The window frame is provided with a plurality of screw holes corresponding to the through holes 222, which are arranged at intervals along the up-down direction of the window frame, and each screw hole is threadedly engaged with a bolt. When the sealing plate assembly is installed on the window frame, one end of the bolt is passed through the through hole 222 and threadedly engaged with the screw hole, thereby fixing the sealing plate assembly to the window frame.

[0050] It should be noted that, in some other embodiments, the second side portion 220 may also be provided with a plurality of buckles, the plurality of buckles are arranged at intervals along the first direction, and the buckles are engaged with the window frame to fix the sealing plate assembly to the window frame. In some embodiments, the second side portion 220 may also be adhered to the window frame by Velcro to fix the sealing plate assembly to the window frame.

[0051] The implementation principle of the first aspect of the embodiment of the present application is: when the first sealing plate 100 and the second sealing plate 200 need to be assembled, the second chamfer first abuts against the first plate portion 120, and at the same time, the first plate portion 120 corresponds to the position of the avoidance portion 2211, and as the second sealing plate 200 slides relative to the first sealing plate 100, the second chamfer slides relative to the first plate portion 120, and the interference between the first sealing plate 100 and the second sealing plate 200 gradually increases, so as to drive the second sealing plate 200 to move along the second direction, so that the first chamfer abuts against the limiting portion 131, so that the limiting portion 131 slides relative to the first chamfer, further increasing the interference between the first sealing plate 100 and the second sealing plate 200, and finally achieving an interference fit between the first sealing plate 100 and the second sealing plate 200, thereby increasing the friction between the first sealing plate 100 and the second sealing plate 200. When the second sealing plate 200 slides relative to the first sealing plate 100, the second sealing plate 200 can be subjected to a greater friction force, so that the two fit more closely, so that when the sealing plate assembly is installed vertically, one end of the bolt is passed through the through hole 222 and cooperates with the screw hole thread, thereby fixing the sealing plate assembly to the window frame, and during installation, there is no need to manually maintain the relative position between the first sealing plate 100 and the second sealing plate 200, which makes user operation more convenient, thereby improving user experience.

[0052] A mobile air conditioner provided in an embodiment of the second aspect of the utility model comprises a sealing plate assembly, and the sealing plate assembly is the sealing plate assembly described in the embodiment of the first aspect of the utility model.

[0053] It is understandable that, referring to Figure 7 The mobile air conditioner also includes a main body 320 and an air duct 310. The main body 320 can cool the indoor hot air. Specifically, the main body 320 includes components such as a compressor, a condenser, an expansion valve, and an evaporator. The compressor compresses the low-pressure and low-temperature refrigerant gas into a high-pressure hot gas, which is then condensed into a liquid through the condenser, and then throttled and reduced in pressure and temperature through the expansion valve, and finally absorbs heat in the evaporator to evaporate into gas, completing a refrigeration cycle. This cycle is repeated continuously to achieve a continuous refrigeration effect. The air duct 310 is used to discharge the heat generated by the main body 320 to the outdoors. One end of the air duct 310 is connected to the main body 320, and the other end is sleeved on the mounting hole 110. When the mobile air conditioner needs to be used, the sealing plate assembly is installed on the window frame. At this time, the mounting hole 110 connects the air outlet of the air duct 310 to the outdoors, and then the heat generated by the main body 320 passes through the air duct 310 and is discharged to the outdoors from the mounting hole 110; when the mobile air conditioner is idle, the sealing plate assembly is removed from the window frame, and the first sealing plate 100 is slid relative to the second sealing plate 200 so that the second sealing plate 200 closes the mounting hole 110 to reduce dust from entering the air duct 310, thereby protecting the main body 320.

[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
