[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 13 A mobile air conditioner 100 according to an embodiment of the present invention is described.

[0038] exist Figure 1-Figure 13 , the height direction is the up-down direction in the figure, the width direction is the left-right direction in the figure, and the thickness direction is the front-back direction in the figure.

[0039] Reference Figure 1-13 As shown, the mobile air conditioner 100 of the embodiment of the utility model comprises: a refrigerant circuit, an outdoor unit 10 and an indoor unit 20. In the refrigerant circuit, the refrigerant circulates through the compressor 11, the condenser, the throttling component and the evaporator in sequence, and one of the condenser and the evaporator is an outdoor heat exchanger 12, and the other is an indoor heat exchanger 23.

[0040] The outdoor unit 10 is located at the lower side, and includes a first casing, and an outdoor fan, a compressor 11, and an outdoor heat exchanger 12 disposed in the first casing.

[0041] The first housing is provided with an outdoor air inlet and an outdoor air outlet. Outdoor air enters the first housing from the outdoor air inlet and then enters the outdoors from the outdoor air outlet. The compressor 11, the outdoor heat exchanger 12 and the outdoor fan are all arranged in the first housing. Outdoor air enters the first housing from the outdoor air inlet and is discharged outdoors from the outdoor air outlet after heat exchange in the first housing.

[0042] The compressor 11 is arranged in the first housing. The compressor 11 is provided with an exhaust port and an air return port. The compressor 11 compresses the refrigerant so that the low-pressure refrigerant becomes a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor 11 from the air return port. After the compressor 11 compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor 11 from the air return port.

[0043] The outdoor heat exchanger 12 is arranged in the first housing, and performs heat exchange between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger 12. The outdoor air entering the first housing from the outdoor air inlet flows to the outdoor heat exchanger 12 to exchange heat with the refrigerant. The outdoor air enters the first housing from the outdoor air inlet and flows to the outdoor heat exchanger 12; the refrigerant flows in the outdoor heat exchanger 12, and the outdoor air exchanges heat with the refrigerant when passing through the outdoor heat exchanger 12; the outdoor air after heat exchange flows to the outdoor air outlet and is discharged to the outside from the outdoor air outlet.

[0044] For example, the outdoor heat exchanger 12 works as a condenser in the cooling mode of the mobile air conditioner 100, so that the refrigerant compressed by the compressor 11 condenses by dissipating heat to the outdoor air through the outdoor heat exchanger 12. The outdoor heat exchanger 12 works as an evaporator in the heating mode of the mobile air conditioner 100, so that the decompressed refrigerant absorbs heat from the outdoor air through the outdoor heat exchanger 12 and evaporates.

[0045] The outdoor fan is located in the first shell. Driven by the outdoor fan, outdoor air enters the first shell from the outdoor air inlet and flows to the outdoor heat exchanger 12. After the outdoor air exchanges heat with the refrigerant at the outdoor heat exchanger 12, the refrigerant is discharged to the outside from the outdoor air outlet driven by the outdoor fan.

[0046] The indoor unit 20 is located on the upper side of the outdoor unit 10 and includes a second shell and an indoor air duct assembly 22, an indoor fan 21 and an indoor heat exchanger 23 arranged in the second shell. The indoor air duct assembly 22 and the indoor heat exchanger 23 define a space for accommodating the indoor fan 21.

[0047] The second housing is located on the upper side of the first housing, and the first housing is connected to the second housing, that is, the second housing is provided with an indoor air inlet and an indoor air outlet 248, and the indoor air enters the second housing from the indoor air inlet and then enters the room from the indoor air outlet 248. The indoor heat exchanger 23, the indoor fan 21 and the indoor air duct are located in the second housing, and the indoor air enters the second housing, and enters the room from the indoor air outlet 248 after heat exchange at the indoor heat exchanger 23.

[0048] The indoor heat exchanger 23 is arranged in the second housing, and performs heat exchange between the indoor air and the refrigerant transmitted in the indoor heat exchanger 23. The indoor air entering the second housing from the indoor air inlet flows to the indoor heat exchanger 23 to exchange heat with the refrigerant. The indoor air enters the second housing from the indoor air inlet and flows to the indoor heat exchanger 23; the refrigerant flows in the indoor heat exchanger 23, and the indoor air exchanges heat with the refrigerant when passing through the indoor heat exchanger 23; the indoor air after heat exchange flows to the indoor air outlet 248, and is discharged to the room from the indoor air outlet 248.

[0049] For example, the indoor heat exchanger 23 works as an evaporator in the cooling mode of the mobile air conditioner 100, so that the decompressed refrigerant absorbs the heat of the indoor air and evaporates through the indoor heat exchanger 23. The indoor heat exchanger 23 works as a condenser in the heating mode of the mobile air conditioner 100, so that the refrigerant compressed by the compressor 11 condenses by dissipating the heat to the indoor air through the indoor heat exchanger 23.

[0050] The indoor fan 21 is arranged in the indoor air duct member. The indoor fan 21 rotates to drive the airflow from the indoor air inlet into the second housing and then flows into the room from the indoor air outlet 248 after heat exchange with the indoor heat exchanger 23. Driven by the indoor fan 21, the indoor air enters the second housing from the indoor air inlet and flows into the indoor heat exchanger 23. After the indoor air exchanges heat with the refrigerant at the indoor heat exchanger 23, the refrigerant is discharged into the room from the indoor air outlet 248 under the drive of the indoor fan 21.

[0051] And, the first housing is connected to the lower side of the second housing. The outdoor unit 10 is located in the first housing, and the indoor unit 20 is located in the second housing.

[0052] The first housing is formed with a first accommodation space and a second accommodation space, in which a compressor and an electric control box are arranged, and in which an outdoor heat exchanger 12 and an outdoor fan are arranged; a third accommodation space is formed in the second housing, in which an indoor air duct assembly 22, an indoor fan 21 and an indoor heat exchanger 23 are arranged. From bottom to top, the first accommodation space, the second accommodation space and the third accommodation space are arranged in sequence.

[0053] Reference Figure 3-13 As shown, the indoor air duct assembly 22 includes: a first air duct member 24 and a second air duct member 25. The first air duct member 24 is connected to one end of the indoor heat exchanger 23. The first air duct member 24 includes an air outlet portion 248. The air outlet portion 248 is provided with an air guide plate for adjusting the air outlet direction.

[0054] The first air duct member 24 is connected to one end of the indoor heat exchanger 23. An indoor fan 21 is arranged in the first air duct member 24. The indoor fan 21 rotates to drive the air flow to enter from the indoor air inlet. After exchanging heat with the indoor heat exchanger 23, the air is blown out from the air outlet portion 248 of the first air duct member 24, thereby reducing or increasing the indoor temperature.

[0055] The second duct member 25 is disposed on the side of the air outlet portion 248 close to the indoor fan 21, and the second duct member 25 and / or the air outlet portion 248 are connected to the other end of the indoor heat exchanger 23. The second duct member 25 includes a volute tongue portion 255 and a connecting portion 256 that are connected to each other. In other words, the second duct member 25 can be connected to the other end of the indoor heat exchanger 23, or the air outlet portion 248 can be directly connected to the other end of the indoor heat exchanger 23 after the second duct member 25 is removed.

[0056] Among them, the volume of the second air duct member 25 is smaller than that of the first air duct member 24, and the second air duct member 25 is arranged on the side of the air outlet portion 248 close to the indoor wind fan 21, adjacent to part of the indoor heat exchanger 23. When the airflow of the indoor air duct passes through the second air duct member 25, since the second air duct member 25 occupies a part of the position of the indoor air duct, under the same air volume, the smaller the space, the faster the flow rate. Therefore, the second air duct member 25 can increase the flow rate of the airflow blown into the room, and the effect of improving the indoor temperature is better.

[0057] The first air duct member 24 is provided with a first matching portion, and the connecting portion is provided with a second matching portion, and the first air duct member 24 and the second air duct member 25 are detachably connected through the first matching portion and the second matching portion. The indoor air duct assembly 22 is detachably connected through the first matching portion and the second matching portion, so that the indoor air duct assembly 22 is split, and when designing and producing the mold, the first air duct member 24 and the second air duct member 25 can be designed and produced separately. The small mold is more convenient and easy to operate during the processing process, which can reduce the processing difficulty and transportation cost, and the production space occupied is relatively small, which reduces the occupation of production equipment and work area, improves production efficiency and utilization of production equipment, and effectively reduces costs.

[0058] In addition, the characteristics of the indoor air duct assembly 22 are different in different products. For example, the indoor fans 21 of different air-conditioning products may have different sizes. By utilizing the split indoor air duct assembly 22, the second air duct component 25 can be replaced according to the different characteristics of the products. Specifically, when the indoor fan 21 is larger, a smaller second air duct component 25 can be replaced, and when the indoor fan 21 is smaller, a larger second air duct component 25 can be replaced.

[0059] For another example, the second air duct component 25 is provided with a volute tongue portion 255. Different indoor heat exchangers 25 and compressor specifications require matching volute tongue portions 255 of different shapes to achieve a better air outlet effect. Therefore, replacing different second air duct components 25 can make the indoor heat exchanger 23 and compressor structures match volute tongue portions 255 of different shapes.

[0060] Moreover, since the second air duct component 25 is smaller in size, less raw materials are required for mold manufacturing and the cost is lower. Only the second air duct component 25 needs to be replaced without replacing the first air duct component 24. There is no need to re-open the mold for the entire indoor air duct assembly 22, and it can adapt to air-conditioning products of different specifications and requirements at a low cost.

[0061] Therefore, by setting up a split indoor air duct component 22, the first air duct 26 component and the second air duct component are designed and produced separately, and the second air duct component 25 can be replaced according to the different characteristics of the product, thereby reducing the mold manufacturing cost, and can reduce the processing difficulty, transportation cost and occupied production space, improve production efficiency, and be able to adapt to air-conditioning products of different specifications and requirements at a low cost.

[0062] Reference Fig.13 As shown, the second duct member 25 is provided with an overlap portion 256, the first duct member 24 is overlapped on the overlap portion 256, and the second duct member 25, the inner side of the first duct member 24, and the other end of the indoor heat exchanger 23 are surrounded by a cavity 27. In other words, the second duct member 25 and a part of the first duct member 24 are overlapped, the interior of the second duct member 25 is hollow, and the second duct member 25, a part of the first duct member 24, and the other end of the indoor heat exchanger 23 are surrounded by a cavity 27, which can save materials and costs while improving the airflow velocity.

[0063] In addition, the cavity 27 can adjust the temperature and air flow of the air outlet portion 248, and as an air buffer zone, reduce the condensation of water vapor caused by the intersection of the cold air flow from the air outlet portion 248 and the indoor hot air flow 256, thereby reducing condensation in the air outlet portion 248.

[0064] Reference Fig.13 As shown, a plurality of partition ribs 28 are provided in the cavity 27, and the plurality of partition ribs 28 are arranged at intervals in the up-down direction. In the front-back direction, the partition ribs are connected to the first air duct member 24 and the second air duct member 25 to form a plurality of sub-cavities in the cavity 27. Specifically, a plurality of partition ribs 28 are provided in the up-down direction of the cavity 27, and the plurality of partition ribs 28 and a part of the first air duct member 24 and the second air duct member 25 form a plurality of sub-cavities, which can strengthen the strength of the first air duct member 24 and the second air duct member 25 on the one hand, and reduce condensation at the air outlet portion 248 on the other hand.

In the embodiment of the utility model, the volute tongue portion 255 can be an arc surface facing the side of the indoor fan 21, that is, a first guide arc surface, which can guide the airflow to smoothly flow out of the air outlet portion 248, control the flow direction and speed of the airflow, reduce turbulence in the airflow, and improve the air outlet efficiency and air volume.

[0066] A second guide slope is provided on the side of the first air duct member 24 facing away from the space accommodating the indoor fan 21. The second guide slope faces the air outlet portion 248, which can adjust the airflow to flow toward the air outlet portion 248, reduce the possibility of turbulence, reduce the noise during air outlet, and improve the comfort of the air-conditioning system.

The relative position of the first air duct member 24 and the second air duct member 25 can be changed by moving the slider 251 inside the slide groove 244, that is, the second air duct member 25 can slide out of the first air duct member 24 by sliding, so that the second air duct member 25 can be conveniently replaced.

[0069] Similarly, sliders 251 may be respectively provided at the upper and lower ends of the first air duct member 24 in the height direction, and slide grooves 244 may be respectively provided at the upper and lower ends of the second air duct member 25 in the height direction.

Among them, the top plate 241 is located at the top of the indoor air duct, which can play the role of closing the indoor air duct, preventing air leakage from affecting the air outlet effect of the mobile air conditioner 100, and can also prevent the external environment from affecting the indoor air duct. Specifically, the top plate 241 can protect the indoor fan 21, filter and other components inside the indoor air duct from being invaded by external objects and dust, thereby extending the service life and improving product quality.

[0071] The bottom plate 242 is located at the bottom of the indoor air duct, and can support the indoor air duct structure and fix the position of the first air duct member 24. In addition, the bottom plate 242 can also be used to connect components such as fans and motors to maintain the stability and fixed position of fans, motors, etc.

[0072] The side panels 243 are connected between the top panel 241 and the bottom panel 242, so that the indoor air duct forms a relatively closed structure, ensuring that the airflow flows along a prescribed path in the indoor air duct, and facilitating the adjustment and control of the airflow rate.
