[0042] Combination Figures 1 to 8 As shown in the drawings, the utility model provides a kind of mobile air conditioner, including shell 100, display module 200, indoor heat exchanger 300 and indoor fan 400.

[0043] Shell 100 includes buckle connection main shell 110 and top cover 120, and the inside of main shell 110 is defined with indoor heat exchange cavity 101, and main shell 110 is provided with indoor air inlet 111, and top cover 120 is provided with indoor air outlet 121, and top cover 120 has circumferential part 122 extending to indoor heat exchange cavity 101 along itself, and circumferential part 122 is provided with a plurality of first ventilation holes 1221, and first ventilation hole 1221 is arranged with indoor air outlet 121.

[0044] Indoor heat exchanger 300 is arranged in indoor heat exchange cavity 101.

[0045] The indoor fan 400 is arranged in the indoor heat exchange cavity 101, and the indoor heat exchanger 300 and the indoor fan 400 are arranged in sequence along an air flow path of air flow from the indoor air inlet 111 to the indoor air outlet 121.

[0046] The surrounding baffle 410 is arranged on the air inlet side of the indoor fan 400 along the circumference of the indoor fan 400 and abuts against the indoor heat exchanger 300, and the plate body of the surrounding baffle 410 towards the top cover 120 is provided with a plurality of second ventilation holes 411, and an oil gas flow channel is formed between the first ventilation hole 1221 and the second ventilation hole 411.

[0047] The display module 200 is arranged on the inner side of the top cover 120, above the indoor heat exchanger 300, and corresponds to the first ventilation hole 1221.

[0048] The inside of the shell 100 is limited to a hollow inner cavity. Wherein, the hollow inner cavity is provided with a partition plate 130, and the partition plate 130 divides the hollow inner cavity into the indoor heat exchange cavity 101 and the outdoor heat exchange cavity 102 which are distributed above and below and independent of each other. Correspondingly, the shell 100 is provided with an indoor air inlet 111 and an indoor air outlet 121 corresponding to the indoor heat exchange cavity 101, and is provided with an outdoor air inlet and an outdoor air outlet corresponding to the outdoor heat exchange cavity 102. Wherein, the indoor heat exchanger 300 and the indoor fan 400 are arranged in sequence in the indoor heat exchange cavity 101 along the flow path of air flow from the indoor air inlet 111 to the indoor air outlet 121; the compressor, the outdoor heat exchanger and the outdoor fan are arranged in sequence in the outdoor heat exchange cavity 102 along the flow path of air flow from the outdoor air inlet to the outdoor air outlet. The indoor air enters the indoor heat exchange cavity 101 through the indoor air inlet 111 under the driving of the indoor fan 400, exchanges heat with the indoor heat exchanger 300, and then enters the indoor environment through the indoor air outlet 121 under the driving of the indoor fan 400, so as to realize the temperature regulation of the indoor environment. Optionally, the indoor air inlet 111 is provided with an air inlet grille to disperse the indoor air entering the indoor heat exchange cavity 101.

[0049] Optionally, the partition plate 130 is fixedly connected with the main shell 110, and the indoor heat exchanger 300 and the indoor fan 400 are arranged on the partition plate 130. The partition plate 130 not only plays a role in separating the indoor heat exchange cavity 101 and the outdoor heat exchange cavity 102, but also can receive the condensate water generated by the indoor heat exchanger 300 and the indoor fan 400. In the case that the mobile air conditioner operates in the refrigeration mode, the indoor heat exchanger 300 acts as an evaporator, and the outdoor heat exchanger acts as a condenser.

[0050] Optionally, the main shell 110 comprises a back plate, the indoor air inlet 111 is arranged on the back plate, and the indoor air outlet 121 is arranged on the top cover 120. Since the indoor heat exchanger 300 and the indoor fan 400 are arranged along the air flow path from the indoor air inlet 111 to the indoor air outlet 121 in sequence, the indoor heat exchanger 300 is arranged towards the indoor air inlet 111, so the indoor air outlet 121 needs to be arranged on the top cover 120 away from the side end of the indoor air inlet 111, that is, arranged close to the front side plate of the main shell 110. Wherein, the main shell 110 further comprises oppositely arranged left and right side plates.

[0051] Further, the display module 200 is arranged above the indoor heat exchanger 300, in order to be able to directly suck the dry air in the room into the space between the top cover 120 and the indoor heat exchanger 300, the first ventilation hole 1221 is arranged on the peripheral portion 122 at a position opposite the indoor air outlet 121. Specifically, the peripheral portion 122 has a left side wall and a right side wall correspondingly connected with the left and right side plates respectively.

[0052] The first ventilation hole 1221 is arranged at one end of the left side wall close to the back plate of the main shell 110, or the first ventilation hole 1221 is arranged at one end of the left side wall close to the back plate of the main shell 110, or the first ventilation hole 1221 is arranged at one end of the left side wall close to the back plate of the main shell 110 and one end of the right side wall close to the back plate of the main shell 110. In this way, the air flowing into the space between the top cover 120 and the indoor heat exchanger 300 through the first ventilation hole 1221 can be prevented from being directly swept away by the air of the indoor air outlet 121.

[0053] Alternatively, the peripheral portion 122 further has a rear side wall corresponding to the back plate, and the first ventilation hole 1221 can also be arranged on the rear side wall.

[0054] Optionally, the indoor fan 400 comprises a first volute 420 and a second volute connected with each other, wherein the first volute 420 is towards the indoor heat exchanger 300, and the fan inlet 401 is arranged on the first volute 420. Wherein, the surrounding baffle 410 is arranged around the circumference of the first volute 420, and extends towards the indoor heat exchanger 300 to abut against the indoor heat exchanger 300. The surrounding baffle 410 can enclose a connecting air duct between the indoor fan 400 and the indoor heat exchanger 300, so that the air flowing out of the indoor heat exchanger 300 can be as much as possible to enter the indoor fan 400, improve the uniformity of the air flowing into the fan inlet 401, and reduce noise.

[0055] The surrounding baffle 410 at least includes a plate body facing the top cover 120, and a plurality of second air vents 411 are arranged on the plate body facing the top cover 120. In the case that the indoor fan 400 is running, dry air in the indoor environment is sucked into the space between the top cover 120 and the indoor heat exchanger 300, and after flowing over the display module 200, the dry air enters the connecting air duct through the second air vents 411, and is further mixed with the air flowing out of the indoor heat exchanger 300 to enter the fan inlet 401, so as to drive the flow of air around the display module 200, and make the high-humidity air around the display module 200 flow out of the space where the display module 200 is located, thereby avoiding condensation on the display module 200 and display module short circuit, and improving safety and service life.

[0056] Optionally, the two ends of the second air vent 411 are rounded.

[0057] Optionally, the indoor fan 400 has a fan outlet 402 corresponding to the indoor air outlet 121, and an air outlet frame 430 is connected between the fan outlet 402 and the indoor air outlet 121.

[0058] By arranging the air outlet frame 430 between the fan outlet 402 and the indoor air outlet 121, the indoor air outlet 121 and the first air vent 1221 can be separated. The air outlet frame 430 can delimit an air outlet air duct between the fan outlet 402 and the indoor air outlet 121, so as to avoid the air flow between the top cover 120 and the indoor heat exchanger 300 through the first air vent 1221 being directly rolled away by the air of the indoor air outlet 121, thereby ensuring the flowability of the air around the display module 200.

[0059] Alternatively, the air outlet frame 430 is not arranged, so that the fan outlet 402 of the indoor fan 400 is directly arranged corresponding to the indoor air outlet 121, and the indoor air outlet 121 is sleeved on the fan outlet 402.

[0060] In the case of the above technical solution, in the case that the indoor fan 400 is running, dry air in the indoor environment can be sucked into the space between the top cover 120 and the indoor heat exchanger 300 through the first air vent 1221, and the dry air flows along the airflow channel towards the second air vent 411 after flowing over the surface of the display module 200, so as to be mixed with the low-temperature air formed after the air entering the indoor heat exchange cavity through the indoor air inlet 111 and exchanging heat with the indoor heat exchanger 300, and then flow into the indoor fan 400 and then flow to the indoor environment through the indoor air outlet 121. In this way, the humid air near the display module 200 can be driven to flow, so as to keep the display module 200 dry, to avoid the problem of display module 200 short circuit caused by condensation, to improve the safety of the display module 200, and to prolong the service life.

[0061] In the optional implementation of the mobile air conditioner, the plurality of first air vents 1221 are arranged in multiple rows and multiple columns.

[0062] By arranging the plurality of first air vents 1221 in multiple rows and multiple columns, the indoor air can be introduced between the top cover 120 and the indoor heat exchanger 300, the smoothness of the air flow is improved, and the flow of the air around the display module 200 is improved.

[0063] Alternatively, due to the height limitation of the peripheral portion 122, only one row of first air vents 1221 is arranged. The row of first air vents 1221 is arranged at intervals in the direction from the front panel to the back panel of the main shell 110.

On the other hand, the first vent hole 1221 and the second vent hole 411 are not too large to avoid too much air flow directly into the top cover 120 and the indoor heat exchanger 300 through the first vent hole 1221, which results in too much noise, and too much air flow between the surrounding baffles 410 through the second vent hole 411.
