As shown in fig. 2, the machine body 20 is provided with a heat exchange air duct, and a return air inlet 21 and an air supply outlet 22 which are respectively communicated with the heat exchange air duct; as shown in fig. 3 to fig. 5, the adaptor shell 30 is installed at the air return opening 21 on the machine body 20, and is provided with an air guiding cavity 31, an air inlet 331 and an air outlet 321 which are respectively communicated with the air guiding cavity 31, and the air outlet 321 is communicated with the air return opening 21; as shown in fig. 1, one end of the air supply pipe 40 is communicated with the air supply outlet 22, and the other end is used for being communicated with the indoor space; one end of the return air pipe 50 is communicated with the air inlet 331, and the other end is used for being communicated with the indoor space.

Specifically, referring to fig. 1, the mobile air conditioner 10 provided in the present embodiment refers to a heat exchange air conditioner in which a moving wheel is installed at the bottom of a machine body 20 and can move freely through the moving wheel; the body 20 of the mobile air conditioner 10 is generally provided with a compressor, an exhaust fan, an electric heater, an evaporator, a condenser, etc., of course, in some other mobile air conditioners 10, the interior of the mobile air conditioners 10 is subjected to heat exchange of indoor air through a water washing structure, the application of the scheme of the present application is not limited to specific mobile air conditioner types, and the existing mobile air conditioners can be improved through the scheme of the present application. When the mobile air conditioner 10 works, indoor air can enter the heat exchange air duct in the machine body 20 through the air return opening 21 on the machine body 20, and is blown back to the indoor from the air supply opening 22 after heat exchange of the evaporator or the condenser, so that heat exchange of the indoor air is realized. The size, position, number, etc. of the return air opening 21 and the supply air opening 22 are not particularly limited herein, and for example, in some embodiments, the body 20 has a substantially square block structure in an outer shape, and has opposite front and rear surfaces, opposite left and right side surfaces, and opposite top and bottom surfaces. The return air inlet 21 is arranged on the left side surface of the machine body 20, and the air supply outlet 22 is arranged on the front surface of the machine body 20, so that the user can quickly determine the position of the air supply outlet 22, and the air outlet direction can be adjusted by adjusting the angle of the machine body 20. For other structures on the body 20, such as an internal air duct structure, a fan structure, etc., reference may be made to the existing mobile air conditioner, and a detailed description thereof will not be provided herein.

In order to solve the problem that the indoor noise is large when the conventional mobile air conditioner 10 is used, as shown in fig. 1, the mobile air conditioner 10 provided by the present application further includes an air supply duct 40 and an air return duct 50, the size, length, material, etc. of the air supply duct 40 and the air return duct 50 are not limited, and can be selected by self according to the actual use condition, for example, in some embodiments, the air supply duct 40 and the air return duct 50 are both hoses, so that the use flexibility of the mobile air conditioner 10 and the air ducts can be improved. One end of the air supply pipe 40 is communicated with the air supply outlet 22 of the machine body 20, and the other end is used for being communicated with the room, so that the air which has completed heat exchange in the heat exchange air duct is conveyed to the room. One end of the return air duct 50 is communicated with the return air inlet 21 of the machine body 20 through the adaptor shell 30, and the other end is communicated with the indoor space, so that the indoor air is conveyed into the air guiding cavity 31 of the adaptor shell 30, and then the air enters the heat exchange air duct of the machine body 20 from the air guiding cavity 31 for heat exchange.

The adapting shell 30 for connecting the body 20 and the return air duct 50 can be made of metal, plastic, alloy and other materials, and the size, shape, manufacturing mode, installation mode and the like of the adapting shell can be designed as required, and only the return air duct 50 and the return air opening 21 on the body 20 need to be communicated. For example, in the present embodiment, as shown in fig. 1 to fig. 4, the air outlet 321 of the adapter housing 30 is communicated with the air guiding cavity 31, and the air outlet 321 is larger than the air return opening 21 of the machine body 20, when the adapter housing 30 is mounted on the machine body 20, the air outlet 321 faces the air return opening 21 to cover the whole air return opening 21. The air inlet 331 of the adapter shell 30 is also communicated with the air guide cavity 31 and is made into a circular opening structure so as to adapt to most circular air pipes in the market and reduce the refitting cost.

In addition, it should be noted that the term "indoor and outdoor" in the present application refers to the mobile air conditioner 10 with respect to the space requiring heat exchange. For example, in a house having a plurality of rooms, when the mobile air conditioner 10 of the present invention is used to cool or heat one of the rooms, the internal space of the room is indoor, and the outside of the room is outdoor (including other spaces in the room and outside the room), and when the mobile air conditioner 10 is placed in the living room, the room is located outdoors relative to the room. Therefore, the indoor space can be any space that is desired to be cooled or heated, such as a space in a tent, a space inside an elevator, and the like, and heat exchange can be performed by using the mobile air conditioner 10 of the present application.

In conclusion, it can be understood that the mobile air conditioner 10 provided by the present application is connected to the air supply opening 22 of the body 20 and the indoor space through the air supply duct 40, and is connected to the air return opening 21 of the body 20 and the indoor space through the air return duct 50, so that the mobile air conditioner 10 can be placed outdoors when in use, and the noise generated by the mobile air conditioner 10 indoors is greatly reduced or even eliminated. And the mobile air conditioner 10 that this application provided is at the during operation, and indoor air enters into the heat transfer wind channel of organism 20 through return air pipe 50 and carries out the heat transfer, then blows back indoor through blast pipe 40, and blows back indoor air and still can enter into organism 20 through return air pipe 50 again after producing the heat exchange and carry out recooling or reheat, so circulate like this and refrigerate or heat the indoor space. And the mobile air conditioner positioned outdoors can directly utilize the ambient outdoor air to discharge the replaced heat to the ambient air, the indoor air does not need to be discharged outdoors in the whole process, a stable heat exchange environment is established for the indoor space, and the indoor heat exchange effect is further effectively improved.

In addition, the mobile air conditioner 10 provided by the application is also connected with the air return opening 21 and the air return pipe 50 of the machine body 20 through the adapter shell 30, on one hand, the existing mobile air conditioner 10 is convenient to modify, only the adapter shell 30 needs to be installed at the air return opening 21 of the machine body 20 during modification, and the modification process is simple and convenient; on the other hand, when the mobile air conditioner 10 with different sizes, shapes and structures is modified, only different adapter shells 30 need to be replaced, the interface structure, the size and the like of the return air duct 50 do not need to be improved, and the modification cost is reduced.

Optionally, in an embodiment, in order to further reduce the noise of the mobile air conditioner 10, please refer to fig. 4 and 5, the air guiding cavity 31 includes a first air cavity 311 and a second air cavity 312, the first air cavity 311 is provided with the air inlet 331, and the second air cavity 312 is provided with the air outlet 321; the first air cavity 311 and the second air cavity 312 are communicated through a communication port 313, and the second air cavity 312 is larger than the first air cavity 311 at least at the position of the communication port 313. Specifically, when the mobile air conditioner 10 is in operation, indoor air may sequentially pass through the air inlet 331, the first air cavity 311, the communication port 313, the second air cavity 312 and the air outlet 321 of the transition shell 30, and since the second air cavity 312 is larger than the first air cavity 311 at least at the position of the communication port 313, when air flows into the second air cavity 312 having a larger space from the first air cavity 311 having a smaller space, the pressure applied to the air may be reduced, and the flow rate is reduced, that is, the air entering the second air cavity 312 may be more gradually and stably than the air entering the first air cavity 311, and may further flow into the air return port 21 of the machine body 20 more smoothly, so as to avoid the problem that the air flows into the air return port 21 in a turbulent and urgent manner to cause large noise, and effectively reduce noise of the mobile air conditioner 10.

In addition, the second air cavity 312 in the adaptor shell 30 is larger than the first air cavity 311 at least at the position of the communication port 313, so that the noise can be reduced, the air exchange amount and the cooling capacity can be improved, and the cooling or heating efficiency can be improved. Specifically, because the second air cavity 312 is communicated with the air return opening 21 of the machine body 20 and is larger than the first air cavity 311, when air flows into the second air cavity 312 from the first air cavity 311, certain buffering can be generated due to pressure reduction, that is, the air can firstly pass through the air return opening 21 of the machine body 20 after being gently and stably arranged in the second air cavity 312 to enter the heat exchange air duct, compared with the situation that the air passes through the air return opening 21 disorderly, the air resistance is smaller, the air exchange amount is larger, the cooling capacity is higher, and the heat exchange effect is better.

Table 1 below shows experimental data on the adaptor housing structure, and the data of air volume, noise and cooling capacity in two structures of "the second air cavity 312 is not larger than the first air cavity 311" and "the second air cavity 312 is larger than the first air cavity 311" are included in the table. As can be seen from the data in the table, when the second air cavity 312 is larger than the first air cavity 311, the air volume and the cooling capacity of the mobile air conditioner 10 are larger (i.e. the heat exchange effect is better), and the noise is smaller.

Table 1: the relationship between the switching shell structure and the air volume, noise and cold quantity of the air conditioner.

In this embodiment, it should be noted that the second air cavity 312 is larger than the first air cavity 311, which means that, in a direction perpendicular to the wind direction, a space enclosed by the inner wall of the second air cavity 312 is larger than a space enclosed by the inner wall of the first air cavity 311. For example, the first air cavity 311 and the second air cavity 312 may be both cylindrical cavity structures, and the inner diameter of the second air cavity 312 is greater than the inner diameter of the first air cavity 311. Or the second air cavity 312 is a square-column cavity structure, the first air cavity 311 is a cylindrical cavity structure, and the length or width of the second air cavity 312 is greater than the inner diameter of the first air cavity 311.

As for the forming manner of the first air cavity 311 and the second air cavity 312, a T-shaped cavity structure may be formed inside the adaptor shell 30, the cavity portion with the smaller inner diameter is the first air cavity 311, and the cavity portion with the larger inner diameter is the second air cavity 312. For example, as shown in fig. 3 and 4, the adapter shell 30 includes a bottom shell 32 and a wind guiding shell 33 connected to each other, the bottom shell 32 is formed with the second air cavity 312 and the wind outlet 321, and the wind guiding shell 33 is formed with the first air cavity 311 and the wind inlet 331; the bottom shell 32 and the air guide shell 33 form a step structure at the joint, and the periphery of the bottom shell 32 at the joint is larger than that of the air guide shell 33 at the joint.

Specifically, in the present embodiment, the bottom casing 32 is substantially a square box structure, one side of the bottom casing 32 in the axial direction is opened to form the air outlet 321, and the other side in the axial direction is connected to the air guiding casing 33. The air guiding shell 33 is substantially a circular tube-shaped structure, and the outer periphery of the position connected with the bottom shell 32 is smaller than the outer periphery of the bottom shell 32, so as to form a step structure, so that the second air cavity 312 in the bottom shell 32 is larger than the first air cavity 311 in the air guiding shell 33. It can be understood that when the bottom shell 32 and the air guide shell 33 form a step structure at the connection position, the structure that the second air cavity 312 is larger than the first air cavity 311 can be realized under the condition that the overall wall thickness of the adaptor shell 30 is uniform.

Optionally, in an embodiment, as shown in fig. 3 to 5, in order to further reduce noise and improve heat exchange effect, the air guiding shell 33 is formed with a curved air guiding curved surface 332, and the curved air guiding curved surface 332 gradually curves and extends from the communication opening 313 to the outer periphery of the bottom shell 32. In this embodiment, referring to a state in which the bottom case 32 is in a lower position and the air guide case 33 is in an upper position, the bottom case 32 has a square structure with four sides on the periphery, and the air guide curved surface 332 extends from the connection portion or the communication port 313 upwards and bends toward the periphery of the bottom case 32, may extend to the left side of the bottom case 32, may also extend to the right side of the bottom case 32, and a specific bending extending direction may be selected according to an orientation situation of the indoor space. It can be understood that because of the air guiding curved surface 332, the air entering the first air cavity 311 from the return air duct 50 can smoothly flow into the second air cavity 312 under the guiding action of the air guiding curved surface 332, so as to reduce noise and improve the air exchange rate.

Still referring to table 1, the table includes data of air volume, noise and cold volume under two structures of "the second air cavity 312 is larger than the first air cavity 311, but the air guiding curved surface 332 is absent" and "the second air cavity 312 is larger than the first air cavity 311, and the air guiding curved surface 332". As can be seen from the data in the table, when the second air cavity 312 is larger than the first air cavity 311 and is provided with the air guiding curved surface 332, the air volume and the cooling capacity of the mobile air conditioner 10 are larger (i.e. the heat exchange effect is better), and the noise is smaller.

Alternatively, in an embodiment, as shown in fig. 2, the body 20 has a front surface on which the supply port 22 is located and a side surface on which the return port 21 is located; the air guiding curved surface 332 is bent and extended from the side where the air inlet 331 and the air outlet 22 are located, so that the air inlet 331 and the air return duct 50 are oriented in the same direction, and the air supply duct 40 and the air return duct 50 can be communicated into the room along the same direction, thereby reducing the installation difficulty of the mobile air conditioner 10 during use, minimizing the lengths of the air supply duct 40 and the air return duct 50, and reducing the cost.

Optionally, in an embodiment, as shown in fig. 3, a fresh air opening 34 communicated with the air guide cavity 31 is further disposed on the adapter shell 30, and a fresh air cover is disposed at the fresh air opening 34 and used for opening and closing the fresh air opening 34. It can be understood that, because the mobile air conditioner 10 provided by the present application can be used outdoors, after the fresh air opening 34 is opened on the adapter shell 30, fresh air can be introduced indoors through the fresh air opening 34, so as to improve the indoor air quality and solve the problem of oxygen supply during internal circulation. And the new trend gets into wind guide cavity 31 back, can get into indoor again after the heat transfer wind channel earlier, avoids new trend and room air to have the difference in temperature and influences the problem of heat transfer effect.

Optionally, in an embodiment, the opening direction of the fresh air opening 34 is downward, so that rainwater or other foreign objects can be prevented from falling into the air guiding cavity 31 of the adaptor shell 30. Optionally, in another embodiment, a fresh air grid is further disposed in the fresh air inlet 34, and the fresh air grid can block various flying foreign objects, so as to prevent the wind guide cavity 31 from being blocked by the flying foreign objects into the adaptor shell 30.

Optionally, in an embodiment, please refer to fig. 2 and fig. 4, a positioning groove and a clamping groove are disposed at the air return opening 21 of the machine body 20, and a positioning buckle 35 inserted into and matched with the positioning groove and a clamping buckle 36 clamped and matched with the clamping groove are disposed at the air outlet 321 of the adaptor shell 30. Specifically, in this embodiment, the positioning fastener 35 and the fastening fastener 36 on the adapting shell 30 are respectively disposed on two opposite sides of the adapting shell 30, the number of the positioning fasteners 35 and the number of the fastening fasteners 36 are respectively plural, and the positions and the numbers of the positioning slots and the fastening slots on the machine body 20 are designed accordingly. When installing switching shell 30 on organism 20, peg graft the constant head tank with location knot 35 in to it can to make joint knot 36 and joint groove joint, the very convenient and fast of installation.

In other embodiments, in order to make the installation of the adapter shell 30 on the machine body 20 more stable, the machine body 20 is further provided with a first screw hole at the air return opening 21, and the adapter shell 30 is further provided with a second screw hole 37 corresponding to the first screw hole at the air outlet 321. After the adaptor shell 30 is stably positioned on the body 20 by the positioning fastener 35 and the clip fastener 36, the first screw hole and the second screw hole 37 are screwed together by screws, so that the adaptor shell 30 and the body 20 can be stably connected.

Optionally, in an embodiment, please refer to fig. 4 and fig. 7, the adaptor shell 30 is provided with a first clamping structure 38 at the air inlet 331, and one end of the air return duct 50, which is communicated with the air inlet 331, is provided with a second clamping structure 51, and the first clamping structure 38 and the second clamping structure 51 are switched between the clamping state and the separating state through relative rotation. Specifically, the first clamping structure 38 may be a clamping protrusion, the second clamping structure 51 may be a ring-shaped clamping groove, and an inlet is formed in a side wall of the ring-shaped clamping groove. During the equipment, earlier with the protruding access & exit that passes through ring groove of card enter into ring groove, make the protruding relative ring groove of card rotate again, until the access & exit on protruding and the ring groove of card misplaces completely, protruding and ring groove of card just is in the joint state, and return air pipe 50 can be connected with switching shell 30 steadily this moment. When the return air duct 50 needs to be detached from the adapter housing 30, the blocking protrusion is rotated relative to the annular clamping groove until the blocking protrusion corresponds to the inlet and outlet of the annular clamping groove, and then the blocking protrusion is pulled out from the annular clamping groove, so that the blocking protrusion and the annular clamping groove can be separated, and the return air duct 50 is detached. It can be seen that the first clamping structure 38 and the second clamping structure 51 are clamped or separated by relative rotation, so that the assembly and disassembly between the return air duct 50 and the adaptor housing 30 are simpler and more convenient.

Of course, the first clamping structure 38 may also be an annular clamping groove, and the second clamping structure 51 may be a clamping protrusion, which may be specifically selected according to actual needs.
