[0044] In combination Figures 1 to 5 As shown in the drawings, the present application provides a mobile air conditioner, comprising a shell 100, an outdoor heat exchanger 200, an outdoor air outlet 300, an air inlet opening 400 and an air inlet assembly 500. Wherein, the inside of the shell 100 forms an outdoor heat exchange cavity 101; the outdoor air outlet 300 is provided on the shell 100 corresponding to the outdoor heat exchange cavity 101, and is arranged to connect the outdoor air outlet pipe 301; the air inlet opening 400 is provided on the shell 100 corresponding to the outdoor heat exchange cavity 101; the outdoor heat exchanger 200 is arranged in the outdoor heat exchange cavity and located on the airflow flow path of the air inlet opening 400 and the outdoor air outlet 300; the air inlet assembly 500 is covered on the air inlet opening 400, and the air inlet assembly 500 is provided with an outdoor air inlet 501 and a supplementary air inlet 502, wherein the outdoor air inlet 501 is arranged to connect the outdoor air inlet pipe 5010, and the supplementary air inlet 502 is arranged to communicate with the indoor environment.

[0045] In the present scheme, in combination Figure 5As shown, the housing 100 is provided with a partition 102, which is arranged to separate the internal space of the housing 100 into an indoor heat exchange cavity and an outdoor heat exchange cavity 101 which are independent of each other and distributed vertically. In this way, the indoor heat exchange cavity can be provided with an indoor heat exchanger, and the housing 100 is correspondingly provided with an indoor air inlet and an indoor air outlet, and the outdoor heat exchange cavity 101 is provided with an outdoor heat exchanger. Indoor air flows into the indoor heat exchange cavity through the indoor air inlet to exchange heat with the indoor heat exchanger, and the heat-exchanged air flows into the indoor environment through the indoor air outlet to achieve the adjustment of the indoor environment. The outdoor air can be introduced into the outdoor heat exchange cavity 101 through the outdoor air inlet 501 to exchange heat with the outdoor heat exchanger 200, so as to ensure the operation of the outdoor heat exchanger 200 and the circulation of the refrigerant between the indoor heat exchanger and the outdoor heat exchanger 200.

[0046] In order to improve the air inlet amount of the outdoor heat exchange cavity 101, in the present scheme, an air inlet assembly 500 is arranged at the air inlet opening 400, and an outdoor air inlet 501 and a supplementary air inlet 502 are arranged on the air inlet assembly 500. By arranging the supplementary air inlet 502, outdoor air can be introduced into the outdoor heat exchange cavity 101 through the outdoor air inlet 501 and the supplementary air inlet 502 at the same time, so as to increase the air inlet area and the air inlet amount, and improve the heat exchange efficiency of the outdoor heat exchanger 200.

[0047] Further, in the case of refrigeration of the mobile air conditioner, the outdoor heat exchanger 200 serves as a condenser, and at this time, the temperature of the outdoor air is higher than that of the indoor air. By arranging the supplementary air inlet 502 to introduce indoor air into the outdoor heat exchange cavity 101, the outdoor air and the indoor air can be mixed, so as to reduce the temperature of the air for heat exchange with the outdoor heat exchanger 200, that is, to increase the temperature difference between the air and the refrigerant in the outdoor heat exchanger 200 (i.e. the condenser), thereby improving the heat exchange efficiency between the air and the outdoor heat exchanger 200 (i.e. the condenser) and improving the cooling effect of the outdoor heat exchanger 200.

[0048] Similarly, in the case of heating of the mobile air conditioner, the outdoor heat exchanger 200 serves as an evaporator, and at this time, the temperature of the outdoor air is lower than that of the indoor air. By arranging the supplementary air inlet 502 to introduce indoor air into the outdoor heat exchange cavity 101, the outdoor air and the indoor air can be mixed, so as to increase the temperature of the air for heat exchange with the outdoor heat exchanger 200, which helps to improve the heat absorption of the refrigerant in the outdoor heat exchanger 200 (i.e. the evaporator) from the air and improve the heat exchange efficiency.

[0049] Optionally, the air inlet assembly 500 is detachably mounted on the air inlet opening 400, so as to facilitate replacement or maintenance of the air inlet assembly 500.

[0050] Alternatively, the air inlet assembly 500 is fixedly installed at the air inlet opening 400. In this way, the air tightness at the air inlet opening 400 is improved. Further, the air inlet assembly 500 is integrally formed with the housing 100, which improves the stability of the housing 100 and the overall appearance of the housing 100.

[0051] Optionally, the air inlet area of the outdoor air inlet 501 is less than the air outlet area of the outdoor air outlet 300. In this way, the pipe diameter of the outdoor air inlet pipe 5010 can be less than the pipe diameter of the outdoor air outlet pipe 301, so that the outdoor air inlet pipe 5010 can be conveniently stored and the appearance is improved.

[0052] Optionally, the sum of the air inlet area of the outdoor air inlet 501 and the air inlet area of the air supplement opening 502 is equal to the air outlet area of the outdoor air outlet 300, or the sum of the air inlet area of the outdoor air inlet 501 and the air inlet area of the air supplement opening 502 is greater than the air outlet area of the outdoor air outlet 300. In this way, the air inlet amount of the outdoor heat exchange cavity 101 can be ensured, so that the air flow flowing into the outdoor heat exchange cavity 101 and the heat exchange effect of the outdoor heat exchanger 200 can be ensured.

[0053] With the mobile air conditioner in the present application, the outdoor heat exchanger is arranged on the air flow path between the air inlet opening and the outdoor air outlet, so that the air flow can pass through the air inlet opening, the outdoor heat exchanger and the outdoor air outlet in sequence. The air inlet assembly is arranged at the air inlet opening, the outdoor air inlet is arranged on the air inlet assembly, and the air supplement opening connected to the indoor environment is arranged at the same time, so that the air inlet amount can be supplemented, the air inlet area of the indoor air inlet can be reduced, the pipe diameter of the outdoor air inlet pipe can be reduced to improve the appearance while ensuring the air inlet amount of the outdoor heat exchange cavity and the heat exchange efficiency of the outdoor heat exchanger. Further, the air temperature of the outdoor environment is different from the air temperature of the indoor environment, the air flow entering the outdoor heat exchange cavity through the outdoor air inlet pipe can be mixed with the air flow entering the outdoor heat exchange cavity through the air supplement opening, so that the heat exchange efficiency of the outdoor heat exchanger can be further improved.

[0054] In combination with Figure 2 , Figure 6As shown, in the optional embodiment of the mobile air conditioner, the shell 100 comprises the lower back plate 110 and the lower side plate 120 connected by bending, the air inlet opening 400 comprises the first opening 410 and the second opening 420, the first opening 410 is arranged on the lower back plate 110, and the second opening 420 is arranged on the lower side plate 120. The air inlet assembly 500 comprises the first air inlet plate 510 and the second air inlet plate 520, wherein the first air inlet plate 510 is arranged on the first opening 410, the first air inlet plate 510 is arranged to form the outdoor air inlet 501, the second air inlet plate 520 is connected to the first air inlet plate 510 by bending, and the second air inlet plate 520 is arranged on the second opening 420, and the second air inlet plate 520 is arranged to form the air supplement inlet 502.

[0055] In this scheme, the shell 100 comprises the back plate and the side plate connected to the back plate by bending. In the case that the mobile air conditioner is placed on the ground, i.e. the mobile air conditioner can be in use, above the partition plate 102 is the upper back plate and the upper side plate, and below the partition plate 102 is the lower back plate 110 and the lower side plate 120.

[0056] The lower back plate 110 and the lower side plate 120 are connected by bending, wherein the first opening 410 is arranged close to the lower side plate 120, and the second opening 420 is arranged close to the lower back plate 110, so that the air inlet assembly 500 can be arranged on the first opening 410 and the second opening 420 at the same time, and the complexity of the structure is reduced. Further, the lower back plate 110 and the lower side plate 120 are connected by bending in an arc shape, so as to improve the structural strength and structural stability between the two.

[0057] Further, by arranging the first opening 410 and the second opening 420 on the lower back plate 110 and the lower side plate 120 connected by bending respectively, the air flow of the outdoor air inlet 501 and the air flow of the air supplement inlet 502 will intersect. In this way, it is helpful to mix the air flows of the outdoor air inlet 501 and the air supplement inlet 502, to ensure the air inlet amount and improve the heat exchange efficiency with the outdoor heat exchanger 200.

[0058] Further, in order to ensure the flow of the air flow, the outdoor air outlet 300 is arranged away from the air inlet opening 400.

[0059] Further, in order to ensure the consistency of the arrangement of the outdoor air outlet pipe 301 and the outdoor air inlet pipe 5010, reduce the length of the outdoor air inlet path and the length of the air outlet path, the outdoor air outlet 300 and the first air inlet plate 510 provided with the outdoor air inlet 501 are arranged on the back plate.

[0060] Further, the shape profile of the first air inlet plate 510 matches the shape profile of the first opening 410 and at least covers the first opening 410, and the shape profile of the second air inlet plate 520 matches the shape profile of the second opening 420 and at least covers the second opening 420. In this way, the first opening 410 and the second opening 420 can be sealed.

[0061] Optionally, the first opening 410 and the second opening 420 are different in shape and size, and correspondingly, the first air inlet plate 510 and the second air inlet plate 520 are different in shape and size. Alternatively, the first opening 410 and the second opening 420 are the same in shape and size, and correspondingly, the first air inlet plate 510 and the second air inlet plate 520 are the same in shape and size.

[0062] Optionally, the lower back plate 110 and the lower side plate 120 are integrally formed, which is conducive to improving the stability and safety of the shell 100, and at the same time, is conducive to reducing the cost.

[0063] Alternatively, the lower back plate 110 and the lower side plate 120 are detachably connected, for example, screw connection, so as to facilitate the replacement or cleaning of the two respectively; or, the lower back plate 110 and the lower side plate 120 are fixedly connected, for example, welding.

[0064] Optionally, the first air inlet plate 510 and the second air inlet plate 520 are integrally formed. In this way, it is conducive to improving the structural stability of the air inlet assembly 500 and facilitating installation.

[0065] Alternatively, the first air inlet plate 510 and the second air inlet plate 520 are detachably connected. In this way, the replacement or cleaning of the first air inlet plate 510 and / or the second air inlet plate 520 can be realized respectively, so as to reduce the maintenance cost.

[0066] Optionally, the first opening 410 and the second opening 420 are communicated with each other, which helps to avoid installing the air inlet assembly 500 in sufficient position and is conducive to reducing the weight of the shell 100 and reducing the cost.

[0067] Alternatively, the first opening 410 is open to the side of the second air inlet plate 520, or the second opening 420 is open to the side of the first air inlet plate 510; or, the first opening 410 and the second opening 420 are independently provided on the first air inlet plate 510 and the second air inlet plate 520 respectively, so as to improve the stability of the air inlet opening 400.

[0068] In combination with Figure 2 , Figure 3As shown, in the optional embodiment of the mobile air conditioner, the mobile air conditioner further comprises an extension 600. The extension 600 is arranged on the inner side of the shell 100 around the periphery of the air inlet opening 400, and the extension 600 is arranged to abut against the first air inlet plate 510 and the second air inlet plate 520.

[0069] Specifically, the extension 600 extends towards the middle part of the air inlet opening 400 and is arranged on the inner side of the shell 100, i.e. on the side of the lower back plate 110 and the lower side plate 120 towards the outdoor heat exchange cavity 101. In this way, when the air inlet assembly 500 is installed, the periphery of the first air inlet plate 510 and the periphery of the second air inlet plate 520 can abut against the extension 600. At the same time, since the extension 600 is recessed towards the outdoor heat exchange cavity 101 relative to the shell 100, the extension 600 can be used to position the first air inlet plate 510 and the second air inlet plate 520, thereby facilitating the installation efficiency of the first air inlet plate 510 and the second air inlet plate 520. Further, by arranging the extension 600, the gap between the first air inlet plate 510 and the shell 100 and the gap between the second air inlet plate 520 and the shell 100 can be shielded, thereby improving the sealing performance of the outdoor heat exchange cavity 101.

[0070] Alternatively, the periphery of the air inlet opening 400 is not provided with an extension to reduce the complexity of the structure.

[0071] Alternatively, the outer side of the extension 600, i.e. the side towards the outside of the shell 100, is spaced apart from the outer side of the shell 100 by a distance equal to the thickness of the first air inlet plate 510 and the second air inlet plate 520. In this way, the outer side of the first air inlet plate 510 and the outer side of the second air inlet plate 520 can be flush with the outer side of the shell 100, avoiding scratching other objects or users, and improving the overall aesthetics of the mobile air conditioner. The thickness of the first air inlet plate 510 and the second air inlet plate 520 is equal to maintain the stability of the structure. Further, the thickness of the first air inlet plate 510 and the second air inlet plate 520 can also be unequal according to actual or experimental needs.

[0072] Alternatively, the outer side of the extension 600, i.e. the side towards the outside of the shell 100, is spaced apart from the outer side of the shell 100 by a distance less than the thickness of the first air inlet plate 510 and the second air inlet plate 520. Since the air inlet flow always generates an impact force on the air inlet assembly 500 when the mobile air conditioner is running, the structural strength of the first air inlet plate 510 and the second air inlet plate 520 can be ensured.

[0073] Alternatively, the extension 600 is integrally formed with the shell 100 to improve the structural stability and reduce the production cost. Alternatively, the extension 600 is not integrally formed with the shell 100 and can be fixedly connected by welding or gluing.

[0074] Combination Figure 2 , Figure 4 and Figure 7 As shown, in the optional embodiment of the above-mentioned portable air conditioner, the portable air conditioner further includes a slot 710 and a buckle 720 that engage with each other. One of the slot 710 and the buckle 720 is disposed in the extension 600 or in the housing 100; the other of the slot 710 and the buckle 720 is disposed in the first air inlet plate 510 and the second air inlet plate 520.
