[0039] 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.

[0040] Reference below Figure 1-Figure 13 A mobile air conditioner 100 according to an embodiment of the present invention is described.

[0041] 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.

[0042] Reference Figure 1-9 As shown, the mobile air conditioner 100 according to the embodiment of the utility model includes: a refrigerant circuit, an outdoor unit 10 , an indoor unit 20 and an air duct assembly 30 .

[0043] The casing 40 includes an outer shell 48 and a chassis 49 . The chassis 49 is located at the bottom of the outer shell 48 . The outer shell 48 is provided with an indoor air inlet, an indoor air outlet, an outdoor air inlet 13 and an outdoor air outlet 14 .

[0044] The outdoor unit 10 is located at the lower side of the casing 40. The outdoor unit 10 includes an outdoor air duct member 11, an outdoor fan, a compressor and an outdoor heat exchanger 12 arranged in the casing 40. When the outdoor fan is running, outdoor air enters the casing 40 from the outdoor air inlet 13, exchanges heat with the outdoor heat exchanger 12, and is then discharged to the outside of the casing 40 from the outdoor air outlet 14.

[0045] The casing 40 is provided with an outdoor air inlet 13 and an outdoor air outlet 14. Outdoor air enters the casing 40 from the outdoor air inlet 13 and then enters the outdoors from the outdoor air outlet 14. The compressor, the outdoor heat exchanger 12 and the outdoor fan are all arranged in the casing 40. Outdoor air enters the casing 40 from the outdoor air inlet 13 and is discharged outdoors from the outdoor air outlet 14 after heat exchange in the casing 40.

[0046] The compressor is arranged in the housing 40. The compressor is provided with an exhaust port and a return port. The compressor compresses the refrigerant so that the low-pressure refrigerant becomes a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor from the return port. After the compressor 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 from the return port.

[0047] The outdoor heat exchanger 12 is arranged in the casing 40, and performs heat exchange between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger 12. The outdoor air entering the casing 40 from the outdoor air inlet 13 flows to the outdoor heat exchanger 12 to exchange heat with the refrigerant. The outdoor air enters the casing 40 from the outdoor air inlet 13 and flows to the outdoor heat exchanger 12; the refrigerant circulates 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 14, and is discharged to the outside from the outdoor air outlet 14.

[0048] 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 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.

[0049] The outdoor fan is located in the casing 40. Driven by the outdoor fan, outdoor air enters the casing 40 from the outdoor air inlet 13 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 14 driven by the outdoor fan.

[0050] The indoor unit 20 is located on the upper side of the casing 40. The indoor unit 20 includes an indoor air duct member 21, an indoor fan and an indoor heat exchanger 22 arranged in the casing 40. When the indoor fan is running, indoor air enters the casing from the indoor air inlet, exchanges heat with the indoor heat exchanger 22, and is then discharged to the outside of the casing 40 from the indoor air outlet.

[0051] An indoor air inlet and an indoor air outlet are also provided on the upper side of the casing 40. Indoor air enters the casing 40 from the indoor air inlet and then enters the room from the indoor air outlet. The indoor heat exchanger 22, the indoor fan and the indoor air duct member 21 are located in the casing 40. Indoor air enters the casing 40 and enters the room from the indoor air outlet after heat exchange at the indoor heat exchanger 22.

[0052] The indoor heat exchanger 22 is arranged in the casing 40, and performs heat exchange between the indoor air and the refrigerant transmitted in the indoor heat exchanger 22. The indoor air entering the casing 40 from the indoor air inlet flows to the indoor heat exchanger 22 to exchange heat with the refrigerant. The indoor air enters the casing 40 from the indoor air inlet and flows to the indoor heat exchanger 22; the refrigerant flows in the indoor heat exchanger 22, and the indoor air exchanges heat with the refrigerant when passing through the indoor heat exchanger 22; the indoor air after heat exchange flows to the indoor air outlet and is discharged into the room from the indoor air outlet.

[0053] For example, the indoor heat exchanger 22 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 22. The indoor heat exchanger 22 works as a condenser in the heating mode of the mobile air conditioner 100, so that the refrigerant compressed by the compressor condenses by dissipating the heat to the indoor air through the indoor heat exchanger 22.

[0054] The indoor fan is arranged in the indoor air duct member 21. The indoor fan rotates, driving the airflow from the indoor air inlet into the housing 40, and then exchanges heat with the indoor heat exchanger 22, and then flows into the room from the indoor air outlet. Driven by the indoor fan, the indoor air enters the housing 40 from the indoor air inlet, flows into the indoor heat exchanger 22, and then the indoor air exchanges heat with the refrigerant at the indoor heat exchanger 22, and then the refrigerant is discharged into the room from the indoor air outlet driven by the indoor fan.

[0055] And, the housing 48 includes a first housing and a second housing, the first housing being 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.

[0056] 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 member 21, an indoor fan and an indoor heat exchanger 22 are arranged. From bottom to top, the first accommodation space, the second accommodation space and the third accommodation space are arranged in sequence.

[0057] Reference Figure 1-13 As shown, the mobile air conditioner 100 further includes: an air duct assembly 30, and the air duct assembly 30 includes: an air inlet duct 31 and an air outlet duct 32. The air duct assembly 30 is located in the third accommodation space.

[0058] One end of the air inlet pipe 31 is connected to the outdoor air inlet 13 of the outdoor air duct member 11, and one end of the air outlet pipe 32 is connected to the outdoor air outlet 14 of the outdoor air duct member 11. The air inlet pipe 31 is used to inhale fresh air from the outside, and the air outlet pipe 32 is used to discharge the heat generated by the outdoor unit 10 to the outside to prevent the indoor air from overheating.

[0059] Specifically, when the outdoor unit 10 is in operation, the outdoor fan in the outdoor air duct 11 rotates, sucking outdoor air from the air inlet 31, and the outdoor air enters the outdoor unit 10 through the outdoor air inlet 13 to exchange heat with the outdoor heat exchanger 12, which is a condenser. The refrigerant compressed by the compressor becomes a high-temperature and high-pressure state and enters the outdoor heat exchanger 12, where it exchanges heat with the outdoor air. The refrigerant in the outdoor heat exchanger 12 condenses and releases heat to become a high-pressure and low-temperature liquid, and enters the indoor unit 20 through the expansion valve. The temperature of the outdoor air after heat exchange increases, and under the action of the outdoor fan, it is discharged to the outside from the outdoor air outlet 14 and the air outlet 32, dissipating the heat in the outdoor unit 10 to the outside.

[0060] The indoor air outlet is arranged on one side of the outer shell 48, and a recessed portion 44 is provided on the other side of the outer shell 48 opposite to the outdoor air outlet 14. The indoor air inlet is arranged on the side of the recessed portion 44 adjacent to the indoor heat exchanger 22, and the outdoor air inlet 13 and the outdoor air outlet 14 are arranged on the side of the recessed portion 44 adjacent to the chassis 49, and the air duct assembly 30 is vertically stored in the recessed portion 44.

[0061] Specifically, the indoor air outlet is arranged at the front side of the housing 48, and a recessed portion 44 is arranged on the rear side of the housing 48 opposite to the outdoor air outlet 14. The indoor air inlet is arranged at a side of the recessed portion 44 adjacent to the indoor heat exchanger 22, that is, at the rear side of the housing 48, and the outdoor air inlet 13 and the outdoor air outlet 14 are arranged at the lower side of the recessed portion 44, and the air duct assembly 30 is vertically stored in the recessed portion 44.

[0062] The air inlet pipe 31 is located on the right side of the recessed portion 44 , and the air outlet pipe 32 is located on the left side of the recessed portion 44 .

[0063] The air duct assembly 30 also includes: a first mounting plate 33 , on which a first air inlet 331 and a first air outlet 332 are provided, the other end of the air inlet duct 31 is connected to the first air inlet 331 , and the other end of the air outlet duct 32 is connected to the first air outlet 332 .

[0064] The first mounting plate 33 is fixedly connected to the upper ends of the air inlet pipe 31 and the air outlet pipe 32, respectively. The first mounting plate 33 is provided with a first air inlet 331. Outdoor air first enters the air inlet pipe 31 from the first air inlet 331, and then enters the outdoor unit 10 through the outdoor air inlet 13 at one end of the air inlet pipe 31. Similarly, the outdoor air after heat exchange first enters the air outlet pipe 32 from the outdoor air outlet 14, and then is discharged to the outside from the first air outlet 332 at the other end of the air outlet pipe 32.

[0065] The first mounting plate 33 is provided with a first clamping portion 333, and the rear side of the housing 48 is provided with a second clamping portion 41, and the first clamping portion 333 and the second clamping portion 41 are clamped and connected. Through the clamping cooperation of the first clamping portion 333 and the second clamping portion 41, the first mounting plate 33 can be fixed to the rear side of the housing 48, and the air inlet pipe 31 and the air outlet pipe 32 can be further fixed.

[0066] That is, when the mobile air conditioner 100 is not in use, the air inlet duct 31, the air outlet duct 32 and the first mounting plate 33 are stored together at the rear side of the housing 48, which can save indoor space. In particular, the place where the mobile air conditioner 100 is needed is generally a scene with a small space and many items, which can prevent the air inlet duct 31 and the air outlet duct 32 from occupying too much indoor space. Storing the air inlet duct 31 and the air outlet duct 32 can also effectively prevent the pipes from being accidentally stepped on or collided, reduce the risk of damage to the air inlet duct 31 and the air outlet duct 32, and help extend the service life of the mobile air conditioner 100.

[0067] When the mobile air conditioner 100 is in use, the first mounting plate 33 and one end of the air inlet duct 31 and the air outlet duct 32 are removed from the rear side of the outer shell 48 and fixed to the window. The first mounting plate 33 and the outer shell 48 are fixed by snapping, which has high stability and firmness. The first mounting plate 33 is not easy to loosen or fall off. Compared with the bolt connection or clamping connection, the snap connection is easier to disassemble and assemble. The operation of taking and placing the first mounting plate 33 is simple and quick, which saves user time and improves the convenience of using the mobile air conditioner 100.

[0068] Moreover, the snap-fit ​​connection part is more compact, neat and beautiful, has no exposed sharp structure, does not require additional accessories, and the first mounting plate 33 has a simple structure, can reduce processing costs, and has good economic benefits.

[0069] Therefore, by providing the first clamping portion 333 and the second clamping portion 41, the disassembly and assembly of the first mounting plate 33 and the rear side of the outer shell 48 is easier and faster. The first mounting plate 33 has a simple structure, which reduces the processing cost of the mobile air conditioner 100 while improving the convenience of user use.

[0070] Reference Figure 5 , Figure 6 and Fig.10 As shown, the first clamping portion 333 is one of a buckle and a slot, and the second clamping portion 41 is the other of the buckle and the slot, and the buckle and the slot are engaged in a clamping fit. In the embodiment of the utility model, the first clamping portion 333 is a slot, and the second clamping portion 41 is a buckle, and the first mounting plate 33 can be fixed to the rear side of the housing 48 through the clamping fit of the buckle and the slot.

[0071] In some embodiments, the first clamping portion 333 may also be a buckle, and the second clamping portion 41 may be a slot.

[0072] The buckle includes: a limit plate 42, which is connected to the housing 48; and two side plates 43, which are arranged on both sides of the limit plate 42 and are connected to the housing 48. Specifically, the buckle and the housing 48 are an integrally formed structure, the buckle protrudes relative to the rear side of the housing 48 and is bent upward, wherein the upwardly bent portion is the limit plate 42, the limit plate 42 is used to be engaged with the card slot on the first mounting plate 33, the limit plate 42 extends into the card slot, and can limit the relative position of the first mounting plate 33 and the housing 48, so that the first mounting plate 33 and the housing 48 can be fixed.

[0073] There are two side plates 43 on both sides of the limiting plate 42. The side plates 43 serve as the supporting structure of the limiting plate 42 to prevent the buckle from tilting or deforming during use, thereby increasing the structural strength, load-bearing capacity and stability of the buckle.

[0074] Reference Figure 9-11 As shown, a first limiting protrusion 421 is provided on one side of the limiting plate 42 facing the housing 48. Specifically, the first limiting protrusion 421 is provided at the upper end of the limiting plate 42, and is used to engage with the edge of the card slot. The first limiting protrusion 421 can limit the relative movement of the first mounting plate 33 and the housing 48 in the height direction to a certain extent.

[0075] For example, the first limiting protrusion 421 is clamped to the edge of the slot on the first mounting plate 33, and the first mounting plate 33 cannot move in the left-right, front-back and up-down directions to the downward side, so that the first mounting plate 33 and the housing 48 can be fixed. However, when the user needs to remove the first mounting plate 33, the first limiting protrusion 421 can be separated from the slot with a little force, and the first mounting plate 33 and the housing 48 can be separated from the top, so that the first mounting plate 33 can be prevented from being accidentally separated from the housing 48 due to misoperation, thereby improving the safety and reliability of the mobile air conditioner 100.

[0076] In addition, a through hole 47 is provided on the shell 48, and the through hole 47 corresponds to the limit plate 42. Specifically, a through hole 47 is provided at a position corresponding to the limit plate 42 on the rear side of the shell 48. During the buckle molding process, structural deformation may occur due to material shrinkage. The through hole 47 is provided on the shell 48 to improve the fluidity of the material, reduce the internal stress of the material during the molding process, reduce the risk of buckle deformation, and improve production efficiency.

Specifically, the rear side of the housing 48 is recessed inward to form the recessed portion 44, and when the mobile air conditioner 100 is not in use, the air inlet pipe 31 and the air outlet pipe 32 can be placed in the recessed portion 44, and the two ends of the recessed portion 44, that is, the two ends of the housing 48 in the left and right directions are respectively provided with a second clamping portion 41, and the first mounting plate 33 is provided with a first clamping portion 333 at both ends in the left and right directions, and the positions of the first clamping portion 333 and the second clamping portion 41 correspond to each other, and the first clamping portion 333 and the second clamping portion 41 are clamped and matched, so that the first mounting plate 33 and the rear side of the housing 48 are fixedly connected.

[0078] Reference Figure 10-11 As shown, the first mounting plate 33 is provided with a plurality of third clamping parts 334 around the first air inlet 331 and the first air outlet 332, and the plurality of third clamping parts 334 are used to clamp with the mounting bracket of the window. That is, when the mobile air conditioner 100 is used, the first mounting plate 33 is removed from the housing 48, and the plurality of third clamping parts 334 are used to fix the first mounting plate 33 on the mounting bracket of the window, so that the outdoor unit 10 can absorb air from the outside and discharge heat.

[0079] In the embodiment of the utility model, the number of the third clamping parts 334 is six, and the six third clamping parts 334 are evenly spaced and distributed on the first mounting plate 33, and are symmetrically arranged in the left and right directions and the front and back directions of the first mounting plate 33, so that the force on the first mounting plate 33 is more uniform, avoiding the buckle or deformation of the first mounting plate 33 caused by uneven force, and improving the quality of the product. In addition, multiple buckles are located in different positions, which increases the user's choice, and there is more adjustment space in the environment where there is no suitable position to fix the window, which increases the usability of the product.

[0080] Reference Fig.11 As shown, the third clamping portion 334 is a buckle, which includes: a clamping portion 3341 and an unlocking portion 3342. The clamping portion 3341 is arranged at the upper end of the first mounting plate 33, the clamping portion 3341 is used to clamp with the mounting bracket, the unlocking portion 3342 is connected to the clamping portion 3341, and the unlocking portion 3342 passes through the first mounting plate 33 and is located at the lower end of the first mounting plate 33, so that the clamping portion 3341 and the mounting bracket are separated when the unlocking portion 3342 is pressed.
