Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and specifically provides a mobile air conditioner. Background Art

[0002] Currently, both wall-mounted and floor-standing air conditioners must be fixed in a fixed location and cannot be moved. Therefore, mobile air conditioners have emerged. Mobile air conditioners mainly come in two types: single-duct and double-duct. These two types primarily refer to outdoor airflow components. A single-duct system draws air from the indoor area to the condenser for heat exchange, where it is then discharged outdoors through an outlet duct. A double-duct system draws air from the outdoor area through an air inlet duct to the condenser for heat exchange, where it is then discharged outdoors through an outlet duct.

[0003] In the prior art, the air duct structure of mobile air conditioners is fixed at the factory in either a single-duct or dual-duct configuration. Therefore, some dual-duct air conditioners can be switched to a single-duct configuration by simply removing the air inlet duct. However, this switch is merely a formal change and can easily lead to insufficient air intake, resulting in poor heat exchange performance for the mobile air conditioner. Furthermore, to facilitate the air duct switch, the air inlet duct diameter should not be too large, which in turn leads to insufficient air intake in the dual-duct configuration. Utility Model Content

[0004] The present application aims to solve the above technical problem, that is, to solve the problem of insufficient air intake when switching between a single air duct structure and a double air duct structure.

[0005] In a first aspect, the present application provides a mobile air conditioner, comprising: an outer shell, an outdoor heat exchange chamber is formed inside, and an outdoor heat exchanger is provided in the outdoor heat exchange chamber; an outdoor air outlet is opened in the outer shell corresponding to the outdoor heat exchange chamber, and is configured to be connected to the outdoor air outlet pipe; an air inlet opening is opened in the outer shell corresponding to the outdoor heat exchange chamber, wherein the outdoor heat exchanger is arranged on the air flow path between the air inlet opening and the outdoor air outlet; an air inlet assembly, comprising a first cover plate and a second cover plate; wherein the first cover plate or the second cover plate is selectively covered on the air inlet opening; a first air inlet connected to the indoor environment is provided on the first cover plate, and the first air inlet is arranged corresponding to the air inlet opening; a second air inlet and a supply air inlet are provided on the second cover plate, the second air inlet is connected to the outdoor air inlet pipe, and the supply air inlet is connected to the indoor environment.

The second cover plate is provided with a second air inlet connected to the outdoor environment and a supplementary air port connected to the indoor environment.

[0035] Combine Figures 1 to 2 As shown, the present application provides a mobile air conditioner, comprising a housing 100, an outdoor air outlet 110, an air inlet opening 120, and an air inlet assembly 300. The interior of the housing 100 defines an outdoor heat exchange chamber 101, within which an outdoor heat exchanger 200 is disposed. The outdoor air outlet 110 is disposed on the housing 100 in correspondence with the outdoor heat exchange chamber 101 and is configured to connect to an outdoor air outlet pipe 111. The air inlet opening 120 is disposed on the housing 100 in correspondence with the outdoor heat exchange chamber 101, with the outdoor heat exchanger 200 disposed in the airflow path between the air inlet opening 120 and the outdoor air outlet 110. The air inlet assembly 300 includes a first cover plate 310 and a second cover plate 320. The first cover plate 310 or the second cover plate 320 is selectively covered on the air inlet opening 120. The first cover plate 310 is provided with a first air inlet 311 connected to the indoor environment. The second cover plate 320 is provided with a second air inlet 321 and a supply air port 322. The second air inlet 321 is connected to the outdoor air inlet pipe 323, and the supply air port 322 is connected to the indoor environment.

[0036] Combine Figure 5As shown, a middle partition 102 is provided in the housing 100. The middle partition 102 is configured to separate the internal space of the housing 100 into an indoor heat exchange chamber and an outdoor heat exchange chamber 101, which are independent of each other and distributed vertically. In this way, an indoor heat exchanger can be provided in the indoor heat exchange chamber, and the housing 100 is provided with an indoor air inlet and an indoor air outlet corresponding to the indoor heat exchange chamber. The indoor air flow can circulate between the indoor environment and the indoor heat exchange chamber through the indoor air inlet and the indoor air outlet, and in this process, heat is exchanged with the indoor heat exchanger, thereby achieving indoor temperature regulation. At the same time, an outdoor heat exchanger 200 is provided in the outdoor heat exchange chamber 101, and an outdoor air outlet 110 and an air inlet opening 120 are provided on the housing corresponding to the outdoor heat exchanger 200, wherein the air inlet opening 120 is provided with an air inlet assembly 300 including a first cover plate 310 and a second cover plate 320. Specifically, the first cover plate 310 is provided with a first air inlet 311 connected to the indoor environment, and the second cover plate 320 is provided with a second air inlet 321 and a supply air port 322. The second air inlet 321 is connected to the outdoor air inlet pipe 323, and the supply air port 322 is connected to the indoor environment.

[0037] When the first cover plate 310 is installed over the air inlet opening 120, the mobile air conditioner switches to a single-duct configuration, and indoor air flows into the outdoor heat exchange chamber 101 through the first air inlet 311. The first air inlet 311 is positioned in correspondence with the air inlet opening 120, thereby ensuring sufficient air flow into the outdoor heat exchange chamber 101 and enhancing the heat exchange efficiency of the outdoor heat exchanger 200. The first air inlet 311 is positioned in correspondence with the air inlet opening 120, and the size of the first air inlet 311 can be aligned with the size of the air inlet opening 120. This maximizes the size of the first air inlet 311, thereby ensuring sufficient air flow.

[0038] When the second cover plate 320 is installed over the air inlet opening 120, the portable air conditioner switches to a dual-duct structure. Outdoor air can enter the outdoor heat exchange chamber 101 through the outdoor air inlet duct 323 and the second air inlet 321. At the same time, part of the indoor air is introduced into the outdoor heat exchange chamber 101 through the supplementary air port 322 to supplement the air intake. This increases the air intake area, thereby increasing the air intake volume and improving the heat exchange efficiency of the outdoor heat exchanger 200.

[0039] Optionally, the outdoor air outlet 110 is configured in a circular shape, and the outdoor air outlet pipe 111 is configured as a circular tube that matches the outdoor air outlet 110. A circular tube has a relatively uniform structure and high structural strength, and airflow within the circular tube is smoother with relatively less resistance, thereby reducing resistance losses and achieving energy savings. Furthermore, the second air inlet 321 is configured in a circular shape, and the outdoor air inlet pipe 323 is configured as a circular tube that matches the second air inlet 321.

[0040] Optionally, the air inlet area of the second air inlet 321 is smaller than the air outlet area of the outdoor air outlet 110. This allows the diameter of the outdoor air inlet pipe 323 to be smaller than the diameter of the outdoor air outlet pipe 111, making it easier to store the outdoor air inlet pipe 323 and improving the aesthetics. Furthermore, the second cover plate 320 is provided with a supplementary air port 322. This supplementary air port 322 replenishes the air intake of the outdoor heat exchange chamber 101, thereby ensuring the heat exchange efficiency of the outdoor heat exchanger 200.

[0041] Optionally, the sum of the air inlet area of the second air inlet 321 and the air inlet area of the air supply port 322 is equal to the air outlet area of the outdoor air outlet 110, or the sum of the air inlet area of the second air inlet 321 and the air inlet area of the air supply port 322 is greater than the air outlet area of the outdoor air outlet 110. In this way, the air intake volume of the outdoor heat exchange chamber 101 can be guaranteed, thereby ensuring the air flow into the outdoor heat exchange chamber 101 and the heat exchange effect of the outdoor heat exchanger 200.

[0042] Alternatively, the second cover plate 320 may be provided with only the second air inlet 321 , and the second air inlet 321 cooperates with the outdoor air outlet 110 to enable the outdoor air flow to circulate in the outdoor heat exchange cavity 101 .

[0043] Optionally, the first cover plate 310 and the second cover plate 320 are respectively detachably connected to the housing 100. In this way, the user can make a selection according to needs.

[0044] Furthermore, when the mobile air conditioner switches to the dual-duct structure and is in cooling mode, the outdoor heat exchanger 200 acts as a condenser, and at this time the temperature of the outdoor air flow is greater than the temperature of the indoor air flow. By setting the air supply port 322, the indoor air flow is introduced into the outdoor heat exchange chamber 101, which can achieve the mixing of the outdoor air flow and the indoor air flow, thereby reducing the temperature of the air flow that exchanges heat with the outdoor heat exchanger 200, that is, increasing the temperature difference between the air flow and the refrigerant in the outdoor heat exchanger 200 (i.e., the condenser), thereby improving the efficiency of the heat exchange between the air flow and the outdoor heat exchanger 200 (i.e., the condenser), and improving the cooling effect on the outdoor heat exchanger 200.

[0045] Similarly, when the mobile air conditioner is in heating mode, the outdoor heat exchanger 200 acts as an evaporator, and at this time the temperature of the outdoor air flow is lower than the temperature of the indoor air flow. By introducing the indoor air flow into the outdoor heat exchange chamber 101 through the setting of the air supply port 322, the outdoor air flow and the indoor air flow can be mixed, thereby increasing the temperature of the air flow that exchanges heat with the outdoor heat exchanger 200, which helps to increase the refrigerant in the outdoor heat exchanger 200 (i.e., the evaporator) to absorb the heat in the air flow and improve the efficiency of heat exchange.

[0046] When the above technical solution is adopted, the airflow entering the outdoor heat exchange chamber passes through the air inlet opening, the outdoor heat exchanger and the outdoor air outlet in sequence. By selecting the first cover plate or the second cover plate of the air inlet assembly to be installed at the indoor inlet, the mobile air conditioner can be switched between a single air duct structure and a double air duct structure. Specifically, when the first cover plate is installed at the air inlet opening, the mobile air conditioner switches to the single air duct structure. Since the first cover plate has a first air inlet corresponding to the indoor inlet, the air intake of the indoor air flow into the outdoor heat exchange chamber can be guaranteed, thereby ensuring the heat exchange efficiency of the outdoor heat exchanger. When the second cover plate is installed at the indoor inlet, the mobile air conditioner switches to the double air duct structure. The second cover plate is provided with a second air inlet connected to the outdoor environment and a supplementary air port connected to the indoor environment. By providing the supplementary air port, the air intake volume can be supplemented, thereby reducing the air intake area of the second air inlet, thereby ensuring the air intake volume of the outdoor heat exchange chamber while reducing the diameter of the outdoor air inlet duct, so as to facilitate installation and facilitate switching of the second cover plate.

[0047] In an optional embodiment of the above mobile air conditioner, in combination with Figures 1 to 6 As shown, the housing 100 includes a lower back plate 130 and a lower side plate 140 that are bent and connected. The air inlet opening 120 includes a first opening 121 and a second opening 122. The first opening 121 is opened in the lower back plate 130, and the second opening 122 is opened in the lower side plate 140. The first cover plate 310 includes a first air inlet plate 312 and a second air inlet plate 313. The first air inlet plate 312 covers the first opening 121, and the second air inlet plate 313 is bent and connected to the first air inlet plate 312 and covers the second opening 122. The first air inlet 311 is opened in the first air inlet plate 312 and / or the second air inlet plate 313.

[0048] Optionally, the housing 100 includes a back panel and side panels bent and connected to the back panel. When the mobile air conditioner is placed on the ground, that is, when the mobile air conditioner is in use, the middle partition 102 is used as the boundary, and the upper back panel and upper side panels are located above the middle partition 102, and the lower back panel 130 and lower side panels 140 are located below the middle partition 102.

[0049] Optionally, the back panel and the side panels are bent and connected and integrally formed, that is, the lower back panel 130 and the lower side panel 140 are bent and connected and integrally formed, so as to improve structural stability. The first opening 121 is opened near the lower side panel 140, and the second opening 122 is set near the lower back panel 130, so that the first cover panel 310 can cover the first opening 121 and the second opening 122, reducing the complexity of the structure.

[0050] Optionally, the first opening 121 and the second opening 122 are respectively provided on the bent lower back plate 130 and the lower side plate 140. The airflow entering the outdoor heat exchange chamber 101 through the first opening 121 and the airflow entering the outdoor heat exchange chamber 101 through the second opening 122 will intersect. In this way, the heat exchange efficiency with the outdoor heat exchanger 200 is improved while ensuring the air intake volume.

[0051] Optionally, the back panel and side panels are connected in an arcuate bend, i.e., the lower back panel 130 and the lower side panel 140 are connected in an arcuate bend. This arcuate bend increases the contact area at the joint, dissipating stress and thereby improving the load-bearing capacity of the structure. Furthermore, the arcuate design makes the joint more compact, reducing the possibility of loosening and displacement, thereby improving structural stability. Furthermore, it also ensures the aesthetics of the housing 100.

[0052] Optionally, the first air inlet 311 is provided on both the first air inlet plate 312 and the second air inlet plate 313. This increases the air inlet area of the outdoor heat exchange chamber 101. Furthermore, the indoor airflow flowing in through the first air inlet plate 312 can be mixed with the indoor airflow flowing in through the second air inlet plate 313. This reduces the airflow velocity while ensuring the airflow volume, thus contributing to a more uniform airflow distribution. This improves the uniformity of heat exchange between the airflow and the outdoor heat exchanger 200 and enhances the heat exchange effect.

[0053] Alternatively, the first air inlet 311 may be provided only on the first air inlet plate 312, with the contour shape and opening area of the first air inlet 311 matching those of the first opening 121. Alternatively, the first air inlet 311 may be provided only on the second air inlet plate 313, with the contour shape and opening area of the first air inlet 311 matching those of the second opening 122. This ensures that the first air inlet 311 has a maximized air intake area, thereby ensuring a sufficient air intake volume.

[0054] Optionally, the first air inlet plate 312 and the second air inlet plate 313 are integrally formed to improve the structural stability of the first cover plate 310 and facilitate installation. Furthermore, the first air inlet plate 312 and the second air inlet plate 313 are connected in an arc shape to further improve the structural strength, structural stability and aesthetics of the first cover plate 310.

[0055] Alternatively, the first air inlet plate 312 and the second air inlet plate 313 are detachably connected to facilitate removal or replacement of the first air inlet plate 312 or the second air inlet plate 313. Optionally, the side of the first air inlet plate 312 adjacent to the second air inlet plate 313 is configured as a first curved side, and the side of the second air inlet plate 313 adjacent to the first air inlet plate 312 is also configured as a second curved side; during installation, the first side and the second side are overlapped to ensure the connection strength between the two.

[0056] In an optional embodiment of the above mobile air conditioner, the first cover plate 310 further includes a first air inlet grille 314 disposed at the first air inlet 311 .

[0057] The first air inlet grille 314 can disperse the incoming air flow, improving the uniformity of the air flow entering the outdoor heat exchange chamber 101. At the same time, it can prevent foreign objects such as mice from entering the outdoor heat exchange chamber 101, thereby improving the safety of components in the outdoor heat exchange chamber 101.

[0058] Optionally, the first air inlet grille 314 is fixedly arranged at the first air inlet 311 to avoid shaking under the blowing of airflow, reduce noise, and improve structural stability.

[0059] Optionally, the setting of the first air inlet grille 314 can separate the first air inlet 311 to form multiple first sub-air inlets, and the first sub-air inlets can extend along the width direction of the first air inlet plate 312, or can extend along the height direction (i.e., vertically) of the first air inlet plate 312, or can be arranged to extend at an inclination relative to the vertical direction.

[0060] Alternatively, an air inlet filter, an insect screen or other mesh structure may be provided at the first air inlet 311. Alternatively, the first air inlet 311 remains open, i.e., no first air inlet grille 314, air inlet filter, insect screen or other mesh structure is provided.

[0061] In an optional embodiment of the above mobile air conditioner, in combination with Figures 1 to 5 、 Figure 7 As shown, the second cover plate 320 includes a third air inlet plate 324 and a fourth air inlet plate 325. The third air inlet plate 324 covers the first opening 121 and is configured to define the second air inlet 321. The fourth air inlet plate 325 is bent and connected to the third air inlet plate 324 and covers the second opening 122. The fourth air inlet plate 325 is configured to define the supplementary air inlet 322.

[0062] Optionally, a second air inlet 321 is provided on the third air inlet plate 324. The second air inlet 321 is connected to the outdoor air inlet pipe 323 to introduce outdoor air into the outdoor heat exchange chamber 101 for heat exchange with the outdoor heat exchanger 200. A supply air inlet 322 is provided on the fourth air inlet plate 325. The contour shape and opening area of the supply air inlet 322 are designed to match those of the second opening 122. This ensures that the supply air inlet 322 has a maximized air inlet area, thereby ensuring a sufficient air flow into the outdoor heat exchange chamber 101.

[0063] In this embodiment, the outdoor airflow from the second air inlet 321 and the indoor airflow from the air supply grille 327 can be mixed, thereby improving the uniformity of the airflow flowing within the outdoor heat exchange chamber 101. Furthermore, the outdoor airflow from the second air inlet 321 and the indoor airflow from the air supply grille 327 have different temperatures. This allows for temperature mixing of the airflows, thereby improving the heat exchange efficiency of the outdoor heat exchanger 200. The specific principles of this have been described above and will not be repeated here.

[0064] Optionally, the third air inlet plate 324 and the fourth air inlet plate 325 are integrally formed to improve the structural stability of the second cover plate 320 and facilitate installation. Furthermore, the third air inlet plate 324 and the fourth air inlet plate 325 are connected in an arc shape to further improve the structural strength, structural stability and aesthetics of the second cover plate 320.

[0065] Alternatively, the third air inlet plate 324 and the fourth air inlet plate 325 are detachably connected to facilitate separate removal, cleaning, replacement, or repair of the third and / or fourth air inlet plates 324 and 325. Optionally, the side of the third air inlet plate 324 proximal to the fourth air inlet plate 325 is configured as a curved third side, and the side of the fourth air inlet plate 325 proximal to the third air inlet plate 324 is also configured as a curved fourth side. During installation, the third and fourth sides overlap to ensure the strength of the connection between them.

[0066] In an optional embodiment of the above mobile air conditioner, the second cover plate 320 further includes a second air inlet grille 326 and a supply air grille 327 . The second air inlet grille 326 is arranged at the second air inlet 321 , and the supply air grille 327 is arranged at the supply air outlet 322 .

[0067] By setting up the second air inlet grille 326, the outdoor air intake air flow can be dispersed to reduce the flow rate, reduce eddy currents and turbulence, and improve the uniformity of the outdoor air intake air flow; at the same time, the second air inlet grille 326 can block impurities in the outdoor air intake air flow, reduce the entry of impurities into the outdoor heat exchange chamber 101, protect the components of the outdoor heat exchange chamber 101, and extend the service life.

[0068] By setting the air supply grille 327, foreign objects with a slightly larger volume in the indoor environment can be prevented from entering the outdoor heat exchange chamber 101, thereby protecting the devices in the outdoor heat exchange chamber 101; at the same time, the setting of the air supply grille 327 can also achieve the purpose of dispersing the indoor air flow entering the outdoor heat exchange chamber 101.

[0069] Alternatively, the second air inlet 321 is provided with a second air inlet grille 326, and the supply air inlet 322 is provided with a filter, or the supply air inlet 322 is open and neither the supply air grille 327 nor the filter is provided. Alternatively, the second air inlet 321 is open and neither the second air inlet grille 326 nor the filter is provided, while the supply air inlet 322 is provided with a supply air grille 327 or a filter. Alternatively, both the second air inlet grille 326 and the supply air grille 327 are open, or both the second air inlet grille 326 and the supply air grille 327 are provided with filters.

[0070] Optionally, the air supply grilles 327 include multiple groups, and the multiple groups of air supply grilles 327 are arranged in sequence along the vertical direction (i.e., the height direction of the fourth air inlet plate 325). Each group of air supply grilles 327 includes first grille holes 3271 and first grille bars 3272 arranged in sequence along the width direction of the lower side plate 140 (i.e., the width direction of the fourth air inlet plate 325). The indoor air flow can enter the outdoor heat exchange chamber 101 through the first grille holes 3271 to achieve dispersion of the air flow. Optionally, the vertical projections of the first grille holes 3271 of two adjacent groups of air supply grilles 327 at least partially overlap. In this way, the dispersion of the outdoor air flow flowing into the outdoor heat exchange chamber 101 can be improved, and the uniformity of the air flow can be improved. Optionally, the first grille holes 3271 can be constructed as an ellipse, a circle, a square, a triangle, a quadrilateral or a polygon.

[0071] Optionally, the first grille holes 3271 may be arranged to be inclined relative to the width direction of the lower side plate 140 (ie, the width direction of the fourth air inlet plate 325 ).

[0072] In an optional embodiment of the above mobile air conditioner, in combination with Figure 7 As shown, the second air inlet 321 is constructed in a circular shape, and the second air inlet grille 326 includes: a plurality of annular grille bars 3261 arranged coaxially with the second air inlet 321; and connecting ribs 3262 extending radially along the second air inlet 321 for connecting the plurality of annular grille bars 3261.

[0073] In this solution, the second air inlet 321 is constructed in a circular shape so as to match the circular outdoor air inlet pipe 323. In this way, the flow resistance of the outdoor air flow when flowing through the outdoor air inlet pipe 323 can be reduced, and the air volume loss can be reduced. By providing a plurality of annular grille bars 3261 arranged coaxially with the second air inlet 321 and connecting ribs connecting the plurality of annular grille bars 3261, the second air inlet 321 is divided into a plurality of sub-air inlets. On the one hand, it can disperse the incoming air flow, reduce the flow rate of the incoming air flow, reduce eddy currents and turbulence, and improve the uniformity of the incoming air flow. On the other hand, it can block impurities in the outdoor air flow, reduce the entry of impurities into the outdoor heat exchange chamber 101, protect the electrical components of the outdoor heat exchange chamber 101, and extend the service life.

[0074] Alternatively, the second air inlet 321 may also be configured in other shapes, such as a triangle, a square, a polygon, or an ellipse.

[0075] Optionally, the connecting ribs 3262 extend radially from the second air inlet 321. This disperses the stress on the annular grille bars 3261 radially, transferring the stress to the air inlet grille and preventing damage to the annular grille bars 3261 due to localized stress concentration. The provision of radially extending connecting ribs 3262 strengthens the connection between the multiple annular grille bars 3261, increasing rigidity and preventing deformation. Furthermore, by arranging connecting ribs radially from the second air inlet 321, multiple annular grille bars 3261 can be connected using a smaller number of connecting ribs 3262, ensuring structural strength while reducing manufacturing costs.

[0076] Alternatively, grille bars extending in a first direction and a second direction are provided at the second air inlet 321 to separate the second air inlet 321, wherein the first direction and the second direction intersect each other. Alternatively, a rotatable air inlet guide plate is provided at the second air inlet 321, and the air inlet guide plate can be rotated to open the second air inlet 321 and adjust the air inlet amount and direction, or to close the second air inlet 321.

[0077] Alternatively, the second air inlet 321 is not provided with the second air inlet grille 326 to reduce the air inlet resistance and the number of parts.

[0078] Optionally, the connecting ribs 3262, the annular grille bars 3261 and the third air inlet plate 324 are integrally formed to improve structural rigidity and structural stability, while also reducing installation steps, saving installation time, and reducing production and installation costs.

[0079] Alternatively, the connecting ribs 3262 are integrally formed with the annular grille bars 3261, and the annular grille bars 3261 are detachably connected to the third air inlet plate 324 to facilitate replacement of the annular grille bars 3261. The detachable connection includes a snap connection, a screw connection, or an adhesive connection. Alternatively, the connecting ribs 3262 are welded to the annular grille bars 3261, and the annular grille bars 3261 are welded to the third air inlet plate 324, or are integrally formed, or are detachably connected.

[0080] Optionally, an outwardly extending annular rib 3211 is provided on the outer side of the third air inlet plate 324 along the circumference of the second air inlet 321. Multiple hooks 3212 are spaced apart along the circumference of the annular rib 3211 on the side facing the second air inlet 321. The provision of the multiple hooks 3212 enables the outdoor air inlet duct 323 to be secured. Furthermore, a guide slope 3213 is provided on the surface of the hook 3212 facing away from the third air inlet plate 324. The guide slope 3213 is inclined toward the third air inlet plate 324 to facilitate installation of the outdoor air inlet duct 323. Specifically, when installing the outdoor air inlet duct 323, the end of the outdoor air inlet duct 323 can be moved along the guide slope 3213 toward the second air inlet 321, thereby causing the multiple hooks 3212 to securely engage the end of the outdoor air inlet duct 323, thereby securing the outdoor air inlet duct 323.

[0081] Alternatively, a mounting ring extending away from the third air inlet plate 324 is provided along the circumference of the second air inlet 321, the inner surface of the mounting ring is provided with a first thread, and the end of the outdoor air inlet pipe 323 is provided with a second thread matching the first thread.

[0082] Alternatively, along the circumference of the second air inlet 321, the third air inlet plate 324 is provided with a plurality of limit slots recessed toward the outdoor heat exchange chamber 101, and the end of the outdoor air inlet pipe 323 is provided with a limit buckle that matches the limit slot.

[0083] Optionally, combined Figure 3 As shown, the outdoor air outlet 110 is provided with an air outlet grille 112. The multiple air outlet grilles 112 are each constructed as annular grille bars and are coaxially arranged with the outdoor air outlet 110. Furthermore, the multiple air outlet grilles 112 are fixedly connected by a plurality of connecting bars 113, which extend radially along the air outlet 110. Furthermore, the connecting bars 113 include two mutually perpendicular first connecting bars and a second connecting bar surrounding the first connecting bars to form an annular cross. This improves the structural stability of the air outlet grilles 112 and prevents deformation of the air outlet grilles 112.

[0084] Alternatively, the outdoor air outlet 110 may also be configured in other shapes, such as a square, an oval, etc. Alternatively, a mesh structure such as a swing leaf or an insect-proof net may also be provided at the outdoor air outlet 110 .

[0085] Furthermore, the outdoor air outlet 110 is disposed on the lower back plate 130. A boss 131 is formed on the outer side of the lower back plate 130, protruding in a direction away from the outdoor heat exchange chamber 101. The boss 131 includes a flat plate portion 1311 arranged parallel to the lower back plate 130 and a connecting portion 1312 fixedly connected to the lower back plate 130. The outdoor air outlet 110 is formed on the flat plate portion 1311. The connecting portion 1312 is provided with a plurality of spaced apart fixing slots 132. The end of the outdoor air outlet pipe 111 is provided with a first fixing clip that cooperates with the fixing slots 132. Furthermore, the flat plate portion 1311 is also provided with spaced apart second fixing clips 133. The end of the outdoor air outlet pipe 111 is also provided with an annular slot that cooperates with the second fixing clip 133. Specifically, there is one fixing slot 132 and at least two second fixing clips 133. The fixing slot 132 and the second fixing clip 133 are arranged opposite each other. When installing the outdoor air outlet duct 111, the second fixing buckle 133 is clamped in the annular groove, and two of the second fixing buckles 133 are respectively abutted against the ends of the annular groove. At the same time, the first fixing buckle is clamped in the fixing groove 132, thereby completing the installation of the outdoor air outlet duct 111.

[0086] Alternatively, the outdoor air outlet 110 may also be configured in other shapes, such as a triangle, a square, a polygon, or an ellipse.

[0087] Alternatively, no boss is provided, and a mounting slot or mounting buckle is provided along the circumference of the outdoor air outlet 110 , and a mounting buckle or mounting slot is provided at the end of the outdoor air outlet pipe 111 , and the mounting slot and the mounting buckle are snap-connected.

[0088] Alternatively, the outer peripheral surface of the boss is provided with an external thread, and the end of the outdoor air outlet pipe 111 is provided with an internal thread matching the external thread.

[0089] In an optional embodiment of the above mobile air conditioner, in combination with Figure 1 、 Figure 2 and Figure 4 As shown, the mobile air conditioner further includes an extension portion 400 . The extension portion 400 is disposed on the inner side of the housing 100 around the periphery of the air inlet opening 120 and is disposed to abut against the first cover plate 310 or the second cover plate 320 .

[0090] Specifically, the extension portion 400 extends toward the middle of the air inlet opening 120 and is disposed on the inner side of the housing 100, that is, on the side of the lower back plate 130 and the lower side plate 140 facing the outdoor heat exchange chamber 101. Thus, when installing the first cover plate 310 or the second cover plate 320, the periphery of the first cover plate 310 or the second cover plate 320 can abut against the extension portion 400. Furthermore, because the extension portion 400 is recessed relative to the housing 100 toward the outdoor heat exchange chamber 101, the extension portion 400 can be utilized to position the first cover plate 310 or the second cover plate 320, thereby facilitating improved installation efficiency of the first cover plate 310 or the second cover plate 320. Furthermore, the provision of the extension portion 400 can block the gap between the first cover plate 310 or the second cover plate 320 and the housing 100, thereby improving the sealing of the outdoor heat exchange chamber 101.

[0091] Alternatively, the extension portion 400 is not provided on the periphery of the air inlet opening 120 to reduce the complexity of the structure.

[0092] Optionally, the distance between the outer side surface of the extension 400, i.e., the side surface facing the outside of the housing 100, and the outer side surface of the housing 100 is equal to the thickness of the first cover plate 310 or the second cover plate 320. In this way, the outer side surface of the first cover plate 310 or the second cover plate 320 can be flush with the outer side surface of the housing 100, avoiding scratches on other objects or users, and improving the overall aesthetics of the mobile air conditioner. The thickness of the first cover plate 310 and the second cover plate 320 are equal to maintain the stability of the structure. Furthermore, according to actual conditions or experimental requirements, the thickness of the first cover plate 310 and the second cover plate 320 may not be equal. In order to maintain the stability of the structure, the thickness of the first air inlet plate 312 and the second air inlet plate 313 are equal, and the thickness of the third air inlet plate 324 and the fourth air inlet plate 325 are equal.

[0093] Alternatively, the distance between the outer side surface of the extension portion 400, i.e., the side surface facing the outside of the housing 100, and the outer side surface of the housing 100 is less than the thickness of the first cover plate 310 or the second cover plate 320. Since the intake airflow always exerts an impact force on the air intake assembly 300 when the mobile air conditioner is in operation, this can ensure the structural strength of the first cover plate 310 or the second cover plate 320.

[0094] Optionally, the extension portion 400 is integrally formed with the housing 100 or fixedly connected by welding or gluing to improve structural stability.

[0095] Alternatively, the extension portion 400 and the housing 100 are not integrally formed, and may be fixedly connected by welding or gluing.
