Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a mobile air conditioner. Background Art

[0002] Air conditioning refers to equipment that uses artificial means to adjust and control the temperature, humidity, flow rate and other parameters of the ambient air in a building or structure. As a type of air conditioning, mobile air conditioning has the advantages of being small in size, requiring no installation, and being able to be moved around in different houses at will. Therefore, mobile air conditioning has been widely used in offices, workshops, machine rooms, houses and other places.

[0003] In the related art, a mobile air conditioner usually integrates components such as a compressor, a condenser, a throttling device, an evaporator and a fan in the same casing, and then places the entire mobile air conditioner indoors to exchange heat between the indoor air and the mobile air conditioner to adjust the temperature of the indoor air conditioner.

[0004] However, during the operation of the above-mentioned mobile air conditioner, since the entire machine is indoors, the noise generated during the operation of the compressor, fan, etc. is all located indoors, which causes relatively high noise indoors and affects the user experience. Summary of the invention

[0005] The embodiments of the present invention provide a mobile air conditioner, which solves the problem in the related art that the mobile air conditioner has high noise and affects the user experience.

[0006] To achieve the above object, the embodiments of the present invention adopt the following technical solutions:

[0007] According to a first aspect involved in the present application, a mobile air conditioner is provided, comprising an indoor unit, an outdoor unit and a first air duct, the indoor unit being movably arranged indoors, the indoor unit comprising a first casing and an indoor fan, the first casing forming a first accommodating chamber and a first air inlet and a first air outlet connected to the first accommodating chamber; the indoor fan being arranged in the first accommodating chamber, and being used to blow the air in the first accommodating chamber to the indoor room through the first air outlet; the outdoor unit being movably arranged outdoors, the outdoor unit comprising a second casing and a heat exchange system, the second casing forming a second accommodating chamber and a second air inlet connected to the second accommodating chamber; the heat exchange system being arranged in the second accommodating chamber, the heat exchange system comprising a compressor, a first heat exchanger, a throttling device and a second heat exchanger which are connected in sequence to form a circulation loop of a refrigerant; the second air inlet being located on the air inlet side of the second heat exchanger; one end of the first air duct being connected to the first air inlet, the other end of the first air duct extending into the second accommodating chamber, and being located on the air outlet side of the second heat exchanger.

[0008] The mobile air conditioner provided by the present application can circulate the refrigerant between the compressor, the first heat exchanger, the throttling device and the second heat exchanger. At the same time, the indoor fan works to allow air to enter the second accommodating chamber from the second air inlet and exchange heat with the refrigerant flowing in the second heat exchanger. The air after heat exchange can enter the first air duct, and after flowing through the first air duct, enter the first accommodating chamber through the first air inlet, and finally be discharged into the room through the first air outlet to adjust the indoor temperature.

[0009] In the above process, since the mobile air conditioner is divided into an indoor unit and an outdoor unit, and the heat exchange system is set in the outdoor unit, the indoor fan is only set in the indoor unit. Therefore, the source of indoor noise is mainly the noise generated when the indoor fan is working, and most of the noise generated when the heat exchange system is working is isolated outdoors. In this way, the indoor noise generated when the mobile air conditioner is working can be significantly reduced, thereby improving the user experience.

[0010] In some embodiments, the mobile air conditioner further comprises a second air duct, one end of which is connected to the room, and the other end of which is connected to the second air inlet, so that the indoor air enters the second accommodating chamber and blows onto the second heat exchanger; in this way, the indoor air can form a circulating air path through the second air duct, the second accommodating chamber, the first air duct, and the first accommodating chamber. At this time, the indoor air can be tightly sealed to improve the indoor cooling or heating effect.

[0011] In some embodiments, a second air outlet connected to the second accommodating chamber is also formed on the second casing; the first air duct includes a first pipe section and a second pipe section, one end of the first pipe section is located in the second accommodating chamber and on the air outlet side of the second heat exchanger, and the other end of the first pipe section passes through the second air outlet; the second pipe section is a retractable bellows, one end of the second pipe section is connected to the other end of the first pipe section, and the other end of the second pipe section is connected to the first air inlet; by setting the second pipe section as a retractable bellows, in the process of moving the rod indoor unit, there is no need to frequently disassemble and assemble the pipe, thereby making the position adjustment process of the indoor unit more convenient.

[0012] In some embodiments, the indoor fan includes a centrifugal fan, the air outlet of the centrifugal fan is connected to the first air outlet, and the air inlet of the centrifugal fan is connected to the first air inlet; setting the indoor fan as a centrifugal fan can reduce the resistance of the first air duct and the second air duct to the air, so as to improve the heating or cooling efficiency of the mobile air conditioner.

[0013] In some embodiments, the second heat exchanger includes an outer shell and multiple rows of refrigerant pipes arranged in the outer shell, and the refrigerant pipes are used for refrigerant circulation; and / or, the second shell is also formed with a third air inlet and a third air outlet connected to the second accommodating chamber; the mobile air conditioner also includes an outdoor fan, the outdoor fan is arranged in the second accommodating chamber and is adjacent to the first heat exchanger, the air inlet of the outdoor fan is connected to the third air inlet, and the air outlet of the outdoor fan is connected to the third air outlet; by arranging multiple refrigerant pipes in the second heat exchanger, the heat exchange efficiency between the second heat exchanger and the air can be improved; through the arrangement of the outdoor fan, the second accommodating chamber can be dissipated and cooled to reduce the temperature of the second accommodating chamber.

[0014] In some embodiments, there are multiple indoor units; the mobile air conditioner also includes multiple third pipe segments, which are retractable bellows; the multiple third pipe segments correspond one-to-one to the multiple indoor units, one end of the multiple third pipe segments is connected to one end of the first air duct, and the other end of a third pipe segment is connected to the first air inlet of an indoor unit; through the above settings, the adjustment range of each indoor unit can be increased, thereby improving the applicability of the mobile air conditioner.

[0015] In some embodiments, there are multiple indoor units and multiple second pipe segments, and the multiple second pipe segments correspond one-to-one to the multiple indoor units; one end of the multiple second pipe segments is connected to the other end of the first pipe segment, and the other end of a second pipe segment is connected to the first air inlet of an indoor unit; through the above arrangement, when the indoor units move, the interference between each other can be reduced, thereby facilitating the separate movement of each indoor unit and improving the flexibility of the movement of each indoor unit.

[0016] In some embodiments, the mobile air conditioner also includes a power cord and a connecting cord, the power cord is electrically connected to the outdoor unit and is used for an external power source; the connecting cord is electrically connected to the indoor unit and to the outdoor unit, and is used to power the outdoor unit to the indoor unit and to transmit signals between the indoor unit and the outdoor unit; in this way, the restriction of the power cord on the movement of the indoor unit can be avoided, thereby improving the flexibility of the movement of the indoor unit.

[0017] In some embodiments, the length of the connecting wire is greater than or equal to the maximum length of the first air duct; the mobile air conditioner also includes a wire receiver, which is disposed on the first housing; when the connecting wire is redundant, the redundant part of the connecting wire is wound around the wire receiver; the setting of the wire receiver can organize the connecting wire more neatly to avoid damage to the connecting wire.

[0056] A mobile air conditioner is an air conditioner that can be moved freely in different houses, so that it can be moved to the corresponding location according to the cooling or heating needs of different locations, making the use of the mobile air conditioner more flexible and convenient.

[0057] In related technologies, such as Figure 1As shown, the mobile air conditioner usually includes only one housing 10. Figure 2 As shown, the mobile air conditioner further includes a first compressor 20, an outdoor heat exchanger 30, a first throttling device (not shown in the figure) and an indoor heat exchanger 40 which are connected in sequence.

[0058] The mobile air conditioner further comprises a first air duct housing 50 and a second air duct housing 60. The first compressor 20, the outdoor heat exchanger 30, the first throttling device, the indoor heat exchanger 40, the first air duct housing 50 and the second air duct housing 60 are all arranged in the installation cavity in the housing.

[0059] The first air duct housing 50 is disposed adjacent to the outdoor heat exchanger 30 , and a first air duct is formed in the first air duct housing 50 ; the second air duct housing 60 is disposed adjacent to the indoor heat exchanger 40 , and a second air duct is formed in the second air duct housing 60 .

[0060] like Figure 1 As shown, a temperature-adjusting air outlet 101 is formed on the chassis 10. Figure 3 As shown, the chassis 10 is further formed with a temperature regulating air inlet 102 , a heat dissipation air inlet 103 and a heat dissipation air outlet 104 .

[0061] The inlet of the first air duct is connected to the heat dissipation air inlet 103 , the outlet of the first air duct is connected to the heat dissipation air outlet 104 , the inlet of the second air duct is connected to the temperature adjustment air inlet 102 , and the outlet of the second air duct is connected to the temperature adjustment air outlet 101 .

[0062] like Figure 4 As shown, when the mobile air conditioner is in use, place the whole mobile air conditioner indoors (such as Figure 4 Then, the heat dissipation air outlet 104 is connected to the outside through the first heat dissipation air duct 70 (such as Figure 4 The heat dissipation air inlet 103 can be connected to the indoor, or can be connected to the outdoor through the second heat dissipation air duct. Here, the heat dissipation air inlet 103 is connected to the indoor as an example for description.

[0063] When the mobile air conditioner is working, the refrigerant in the mobile air conditioner can circulate in the circulation loop formed by the first compressor 20, the outdoor heat exchanger 30, the first throttling device and the indoor heat exchanger 40. At the same time, the indoor air can enter the second air duct from the temperature-controlled air inlet 102 under the action of the fan arranged in the second air duct, and exchange heat with the indoor heat exchanger 40 in the process of flowing through the second air duct, so as to adjust the temperature of the air in the second air duct. The temperature-regulated air is discharged into the room from the temperature-regulated air outlet 101 to adjust the indoor temperature.

[0064] Furthermore, indoor air can enter the first air duct from the heat dissipation air inlet 103 under the action of the fan in the first air duct, and after heat exchange with the hot air in the chassis 10, it is discharged to the outside through the heat dissipation air outlet 104 and the first heat dissipation air duct 70.

[0065] It can be seen from this that during the operation of the existing mobile air conditioner, the first compressor 20, the fan provided in the first air duct, and the fan provided in the second air duct are all running indoors, and the noise generated by the first compressor 20, the fan provided in the first air duct, and the fan provided in the second air duct during the operation is all indoors, thus affecting the user experience effect.

[0066] In addition, the mobile air conditioner has a large overall size, occupies a large space when placed indoors, and is inconvenient to move.

[0067] In addition, the whole unit of the mobile air conditioner is placed indoors, and part of the heat generated during the operation of the mobile air conditioner will be dissipated into the room, which will affect the indoor temperature and further affect the cooling effect of the mobile air conditioner.

[0068] Based on this, the embodiment of the present application provides a mobile air conditioner, such as Figure 5 As shown, the mobile air conditioner includes an indoor unit 1 and an outdoor unit 2. The indoor unit 1 is movable and arranged indoors (such as Figure 5 The outdoor unit 2 is movably arranged outdoors (eg, Figure 5 B side shown in FIG.

[0069] Specifically, Figure 6 As shown, the indoor unit 1 includes a first housing 11. A plurality of first universal wheels 12 are arranged at the bottom of the first housing 11, and the first housing 11 can be moved indoors by rotating the first universal wheels 12, thereby moving the indoor unit 1 indoors to adjust the position of the indoor unit 1.

[0070] like Figure 7 As shown, the outdoor unit 2 includes a second housing 21. A plurality of second universal wheels 22 are arranged at the bottom of the second housing 21, and the second housing 21 can be moved outdoors by rotating the second universal wheels 22, thereby moving the outdoor unit 2 outdoors to adjust the position of the outdoor unit 2.

[0071] like Figure 6 As shown, the first housing 11 is formed with a first accommodating chamber 13 and a first air inlet 14 and a first air outlet 15 connected to the first accommodating chamber 13. The indoor unit 1 also includes an indoor fan 16. The indoor fan 16 is arranged in the first accommodating chamber 13. Under the action of the indoor fan 16, air can enter the first accommodating chamber 13 through the first air inlet 14 and be discharged indoors through the first air outlet 15.

[0072] like Figure 7 As shown, the second housing 21 is formed with a second accommodating chamber 23 and a second air inlet 24 communicating with the accommodating chamber 23. Air can enter the second accommodating chamber 23 through the second air inlet 24.

[0073] like Figure 8 As shown, the outdoor unit 2 further includes a heat exchange system 25. The heat exchange system 25 is disposed in the second accommodating chamber 23. The heat exchange system 25 is used to exchange heat with the air entering the second accommodating chamber 23.

[0074] like Figure 5 As shown, the mobile air conditioner further includes a first air duct 3. The first air duct 3 is connected to the second accommodating chamber 23 and the first air inlet 14. When the indoor fan 16 is working, air can enter the second accommodating chamber 23 from the second air inlet 24, and the air entering the second accommodating chamber 23 can exchange heat with the heat exchanger system.

[0075] The air after heat exchange with the heat exchange system 25 can enter the first air duct 3, and after flowing through the first air duct 3, enter the first accommodating chamber 13 through the first air inlet 14, and finally be discharged into the room through the first air outlet 15 to adjust the indoor temperature.

[0076] Through the above arrangement, the mobile air conditioner can be divided into an indoor unit 1 and an outdoor unit 2, and the heat exchange system 25 is arranged in the outdoor unit 2, and the indoor fan 16 is arranged only in the indoor unit 1. When the mobile air conditioner is working, the indoor unit 1 is placed indoors, and the outdoor unit 2 is placed outdoors. The source of indoor noise is mainly the noise generated when the indoor fan 16 is working, and most of the noise generated when the heat exchange system 25 is working is isolated outdoors.

[0077] In this way, the indoor noise generated by the mobile air conditioner when it is working can be significantly reduced, thereby improving the user experience.

[0078] Furthermore, only the indoor fan 16 is disposed in the first housing 11 of the indoor unit 1, which can also reduce the volume of the indoor unit 1, thereby reducing the space occupied by the indoor unit 1 indoors, and can make the indoor unit 1 lighter, so as to facilitate the use of the indoor unit 1 for movement.

[0079] In addition, the mobile air conditioner is divided into an indoor unit 1 and an outdoor unit 2. The heat generated by the heat exchange system 25 in the outdoor unit 2 when it is working is dissipated outdoors, and only the heat generated by the indoor fan 16 when it is working is dissipated indoors, thereby reducing the impact of the heat generated by the mobile air conditioner on the indoor temperature, thereby improving the cooling effect of the mobile air conditioner.

[0080] The heat exchange system 25 may be a heat exchange pipe. In this case, a medium may be introduced into the heat exchange pipe, so that the medium in the heat exchange pipe exchanges heat with the air in the second accommodation chamber 23 to adjust the temperature of the air in the second accommodation chamber 23, thereby adjusting the indoor temperature. When the mobile air conditioner is heating, the medium may be hot water, and when the mobile air conditioner is cooling, the medium may be ice water, liquid nitrogen, compressed air, etc.

[0081] like Figure 8 As shown, the heat exchange system 25 may further include a compressor 251, a first heat exchanger 252, a throttling device (not shown in the figure) and a second heat exchanger 253 which are sequentially connected to form a circulation loop of the refrigerant.

[0082] At this time, if Figure 5 As shown, the second air inlet 24 is located at the air inlet side of the second heat exchanger 253, one end of the first air duct 3 is connected to the first air inlet 14, and the other end of the first air duct 3 extends into the second accommodating cavity 23 and is located at the air outlet side of the second heat exchanger 253. Figure 7 As shown, a second air outlet 26 communicating with the second accommodating chamber 23 is also formed on the second housing 21 , and the other end of the first air duct 3 passes through the second air outlet 26 and extends into the second accommodating chamber 23 .

[0083] In this way, when the indoor fan 16 is working, air can enter the second accommodating chamber 23 from the second air inlet 24 and blow onto the second heat exchanger 253, so that the air entering the second accommodating chamber 23 can exchange heat with the second heat exchanger 253. The air after heat exchange with the second heat exchanger 253 will enter the first air duct 3, and after flowing through the first air duct 3, enter the first accommodating chamber 13 through the first air inlet 14, and finally be discharged into the room through the first air outlet 15 to adjust the indoor temperature.

[0084] When the mobile air conditioner is cooling, the first heat exchanger 252 serves as a condenser and the second heat exchanger 253 serves as an evaporator.

[0085] The refrigerant in the mobile air conditioner is compressed into a high-temperature and high-pressure refrigerant by the compressor 251. The high-temperature and high-pressure refrigerant flows out of the compressor 251 and enters the first heat exchanger 252, and is condensed into a high-temperature and high-pressure liquid refrigerant through the first heat exchanger 252. The high-temperature and high-pressure liquid refrigerant flows out of the first heat exchanger 252 and enters the throttling device, and is throttled and reduced in pressure through the throttling device to become a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant flows out of the throttling device and enters the second heat exchanger 253, and is evaporated into a low-temperature and low-pressure gaseous refrigerant through the second heat exchanger 253. The low-temperature and low-pressure gaseous refrigerant flows out of the second heat exchanger 253 and enters the compressor 251 to be compressed again.

[0086] When the refrigerant evaporates through the second heat exchanger 253 , the air blown onto the second heat exchanger 253 can be cooled, thereby lowering the indoor temperature.

[0087] When the mobile air conditioner is heating, the first heat exchanger 252 serves as an evaporator and the second heat exchanger 253 serves as a condenser.

[0088] The refrigerant in the mobile air conditioner is compressed into a high-temperature and high-pressure refrigerant by the compressor 251. After the high-temperature and high-pressure refrigerant flows out of the compressor 251, it enters the second heat exchanger 253 and is condensed into a high-temperature and high-pressure liquid refrigerant through the second heat exchanger 253. After the high-temperature and high-pressure liquid refrigerant flows out of the second heat exchanger 253, it enters the throttling device and is throttled and reduced in pressure through the throttling device to become a low-temperature and low-pressure liquid refrigerant. After the low-temperature and low-pressure liquid refrigerant flows out of the throttling device, it enters the first heat exchanger 252 and evaporates into a low-temperature and low-pressure gaseous refrigerant through the first heat exchanger 252. After the low-temperature and low-pressure gaseous refrigerant flows out of the first heat exchanger 252, it enters the compressor 251 and is compressed again.

[0089] During the condensation of the refrigerant through the second heat exchanger 253, the air blown onto the second heat exchanger 253 can be heated up, thereby raising the indoor temperature.

[0090] It should be noted that the throttling device can be an electronic expansion valve, a thermal expansion valve, a capillary tube, etc.

[0091] Since the first heat exchanger 252 and the second heat exchanger 253 generate condensed water during operation, Figure 8 As shown, the outdoor unit 2 further includes a first water receiving pan 27 and a second water receiving pan 28. The first water receiving pan 27 is disposed at the lower side of the first heat exchanger 252, and is used to receive condensed water generated when the first heat exchanger 252 is working. The second water receiving pan 28 is disposed at the lower side of the second heat exchanger 253, and is used to receive condensed water generated when the second heat exchanger 253 is working.

[0092] Furthermore, since the heat exchange system 25 is disposed in the second casing 21 of the outdoor unit 2 , the heat generated during the operation of the mobile air conditioner is usually accumulated in the second casing 21 , resulting in a higher temperature in the second casing 21 .

[0093] In order to reduce the temperature in the second housing 21, Figure 7 As shown, the second housing 21 is also formed with a third air inlet (not shown in the figure) and a third air outlet 29 connected to the second accommodating chamber 23; the mobile air conditioner also includes an outdoor fan 4, which is arranged in the second accommodating chamber 23 and is adjacent to the first heat exchanger 252. The air inlet of the outdoor fan 4 is connected to the third air inlet, and the air outlet of the outdoor fan 4 is connected to the third air outlet 29.

[0094] Through the operation of the outdoor fan 4, outdoor air can enter the second accommodating chamber 23 through the third air inlet and exchange heat with the hot air in the second accommodating chamber 23. The air after heat exchange is discharged to the outside from the third air outlet 29, thereby reducing the temperature in the second accommodating chamber 23 to ensure the normal operation of the heat exchange system 25.

[0095] In addition, the air entering the second accommodating chamber 23 through the second air inlet 24 can be outdoor air. At this time, the indoor air can be loosely sealed, or an exhaust port can be opened indoors to ensure the indoor pressure.

[0096] The air entering the second accommodating chamber 23 from the second air inlet 24 may also be indoor air. Fig. 9 As shown, the mobile air conditioner also includes a second air duct 5. The second air duct 5 is arranged outdoors (such as Fig. 9 B side shown in FIG), one end of the second air duct 5 is connected to the indoor (such as Fig. 9 The other end of the second air duct 5 is connected to the second air inlet 24, so that the indoor air enters the second accommodating chamber 23 and is blown onto the second heat exchanger 253.

[0097] In this way, indoor air can form a circulating air path through the second air duct 5, the second accommodating chamber 23, the first air duct 3, and the first accommodating chamber 13. At this time, the indoor air can be tightly sealed to improve the indoor cooling or heating effect.

[0098] It should be noted that one end of the second air duct 5 can be connected to the room by passing one end of the second air duct 5 through the window of the house and extending it into the room. In this case, a first air duct bracket can be set on the window to support and fix one end of the second air duct 5. In addition, the other end of the second air duct 5 can be connected to the second air inlet 24 through a joint to achieve the connection between the other end of the second air duct 5 and the second air inlet 24.

[0099] In some embodiments, when the indoor unit 1 needs to be moved, in order to avoid the first air duct 3 from restricting the movement of the indoor unit 1, the length of the first air duct 3 can be adjusted. The first air duct 3 can be made of a flexible material, such as a plastic material, to reduce the weight of the first air duct 3 and facilitate the bending of the first air duct 3 when the indoor unit 1 moves.

[0100] Exemplarily, the first air duct 3 may be a corrugated tube. At this time, one end of the first air duct 3 extends into the second accommodating cavity 23 and is fixed to the second housing 21, and the other end of the first air duct 3 passes through the window of the house and is connected to the first air inlet 14 of the first housing 11 through a joint.

[0101] Exemplarily, the first air duct 3 can be configured as a detachable multi-section pipe, the number of pipe sections is selected according to the distance between the indoor unit 1 and the outdoor unit 2, and the selected pipe sections are connected together through joints.

[0102] For example, Fig. 9 As shown, the first air duct 3 includes a first pipe section 31 and a second pipe section 32. One end of the first pipe section 31 is located in the second accommodating cavity 23 and at the air outlet side of the second heat exchanger 253, and the other end of the first pipe section 31 passes through the second air outlet 26; one end of the second pipe section 32 is connected to the other end of the first pipe section 31, and the other end of the second pipe section 32 is connected to the first air inlet 14. Fig.10 As shown, the second pipe section 32 is a telescopic bellows.

[0103] By setting the second pipe section 32 as a retractable bellows, when the indoor unit 1 is moved, the length of the first air duct 3 can be adjusted by stretching or compressing the second pipe section 32 so that the length of the first air duct 3 meets the distance between the indoor unit 1 and the outdoor unit 2.

[0104] Through the above-mentioned adjustment method, in the process of moving the rod indoor unit 1, there is no need to frequently disassemble and assemble the pipeline, which can make the position adjustment process of the indoor unit 1 more convenient.

[0105] It should be noted that the first pipe section 31 is located outdoors, the second pipe section 32 is located indoors, and the other end of the first pipe section 31 is connected to one end of the second pipe section 32 through a joint at the window of the house so that the first pipe section 31 and the second pipe section 32 are connected.

[0106] Since the outdoor unit 2 rarely moves, the first pipe section 31 can be a non-retractable straight pipe or a retractable corrugated pipe.

[0107] The first pipe section 31 may be a continuous pipe. At this time, one end of the first pipe section 31 extends into the second accommodating cavity 23 and is fixedly connected to the second housing 21 .

[0108] like Fig. 9 As shown, the first pipe section 31 may also include an air duct 311 and a heat exchange air duct 312 formed in the shell. The second accommodating chamber 23 may be divided into a channel by a shelf disposed in the second accommodating chamber 23 to form the heat exchange air duct 312, and one end of the heat exchange air duct 312 is located at the air outlet side of the second heat exchanger 253, and the other end of the heat exchange air duct 312 is connected to the second air outlet 26, one end of the air duct 311 is connected to the second air outlet 26, and is fixed on the second housing 21 so that the air duct 311 is connected to the heat exchange air duct 312, and the other end of the air duct 311 is connected to one end of the second pipe section 32.

[0109] In some embodiments, during operation of the mobile air conditioner, the first air duct 3 and the second air duct 5 will cause a longer air flow line, thus causing a certain resistance to the air flow, thereby affecting the cooling efficiency of the mobile air conditioner.

[0110] Based on this, the indoor fan 16 includes a centrifugal fan 161. The air outlet of the centrifugal fan 161 is connected to the first air outlet 15, and the air inlet of the centrifugal fan 161 is connected to the first air inlet 14. In this way, the air can be pumped by the centrifugal fan 161 to circulate between the room, the second air duct 5, the second accommodating chamber 23, the first air duct 3 and the first accommodating chamber 13.

[0111] Since the centrifugal fan 161 has a higher pressure than a traditional cross-flow fan, setting the indoor fan 16 to the centrifugal fan 161 can reduce the resistance of the first air duct 3 and the second air duct 5 to the air, so as to improve the heating or cooling efficiency of the mobile air conditioner.

[0112] It should be noted that the centrifugal fan 161 may be a forward centrifugal fan.

[0113] In some embodiments, Figure 2 As shown, in a conventional mobile air conditioner, a second air duct housing 60 is disposed next to the second heat exchanger 253. Compared with the conventional mobile air conditioner, the mobile air conditioner of the present application is divided into an indoor unit 1 and an outdoor unit 2, and the indoor fan 16 is disposed in the indoor unit 1. Therefore, the second air duct housing 60 does not need to be disposed next to the second heat exchanger 253 in the outdoor unit 2, so that the space next to the second heat exchanger 253 can be saved.

[0114] At this time, the volume of the second heat exchanger 253 can be increased to set a plurality of refrigerant pipes 2532 in the second heat exchanger 253. Specifically, as Fig.11 As shown, the second heat exchanger 253 includes a shell 2531 and a plurality of rows of refrigerant pipes 2532 disposed in the shell 2531 , and the refrigerant pipes 2532 are used for refrigerant circulation.

[0115] In a conventional mobile air conditioner, the number of rows of the refrigerant pipes 2532 in the second heat exchanger 253 is usually three. In the mobile air conditioner of the present application, since there is sufficient space next to the second heat exchanger 253 in the outdoor unit 2, the number of the refrigerant pipes 2532 in the second heat exchanger 253 can be set to four rows, five rows, or even more.

[0116] In this way, the number of refrigerant pipes 2532 in the second heat exchanger 253 is large, and the amount of refrigerant flowing through the second heat exchanger 253 is large, thereby increasing the heat exchange efficiency between the refrigerant and the air blown onto the second heat exchanger 253, and further improving the cooling or heating efficiency of the mobile air conditioner.

[0117] Furthermore, after the number of rows of refrigerant pipes 2532 in the second heat exchanger 253 is increased, the number of refrigerant pipes 2532 in each row of refrigerant pipes 2532 can be reduced while ensuring the heat exchange efficiency of the second heat exchanger 253, thereby reducing the height of the second heat exchanger 253 and further reducing the height of the outdoor unit 2, thereby reducing the volume of the outdoor unit 2 and facilitating the movement of the outdoor unit 2.

[0118] It should be noted that in the second heat exchanger 253, each refrigerant pipe 2532 in each row of refrigerant pipes 2532 is arranged in a vertical direction (eg Fig.11 The multiple rows of refrigerant are arranged along the thickness direction of the second heat exchanger 253 (eg, Fig.11 Arranged in direction Y) as shown in FIG.

[0119] In some embodiments, since the mobile air conditioner is divided into an indoor unit 1 and an outdoor unit 2, the number of indoor units 1 can be set to multiple. Multiple indoor units 1 can be set at different locations, and after the air is heat exchanged by the heat exchange system 25 of one outdoor unit 2, the heat exchanged air can be diverted to multiple indoor units 1 to achieve heating or cooling of multiple locations at the same time.

[0120] In this way, the cooling or heating space of the mobile air conditioner can be increased. In addition, the indoor unit 1 to be moved can be selected according to the distance between the location to be cooled and different indoor units 1, thereby improving the flexibility of the movement of the indoor unit 1 and reducing the movement range of the indoor unit 1, thereby improving the user experience.

[0121] It should be noted that the multiple indoor units 1 can be controlled individually, so that the number of indoor units 1 to be turned on can be selected according to the required cooling position and cooling space.

[0122] At this time, multiple indoor units 1 can be connected to the outdoor unit 2 in multiple ways.

[0123] For example, Fig.12 As shown, the mobile air conditioner further includes a plurality of third pipe segments 6. The third pipe segment 6 is a retractable corrugated pipe; the plurality of third pipe segments 6 correspond to the plurality of indoor units 1 one by one, one end of the plurality of third pipe segments 6 is connected to one end of the first air duct 3, and the other end of one third pipe segment 6 is connected to the first air inlet 14 of one indoor unit 1.

[0124] At this time, the first air duct 3 can be a corrugated pipe, or a detachable multi-section pipe, and can also include a first pipe section 31 and a second pipe section 32.

[0125] Among them, the connection between the first air duct 3 and multiple third pipe segments 6 can be achieved by setting an air distributor at one end of the first air duct 3, or by opening multiple connecting holes on the side wall of one end of the first air duct 3 located in the room, and one connecting hole is connected to a third pipe segment 6 through a joint.

[0126] Since part of the first air duct 3 is located indoors and the length of the first air duct 3 is adjustable, setting the third pipe section 6 as a length-adjustable corrugated pipe can increase the adjustment range of each indoor unit 1, thereby improving the applicability of the mobile air conditioner.

[0127] For example, Fig.13 As shown, the first air duct 3 includes a first pipe section 31 and a second pipe section 32, wherein the second pipe section 32 is a retractable corrugated pipe. At this time, the number of the second pipe sections 32 is also multiple, and the multiple second pipe sections 32 correspond to the multiple indoor units 1 one by one; one end of the multiple second pipe sections 32 is connected to the other end of the first pipe section 31, and the other end of one second pipe section 32 is connected to the first air inlet 14 of one indoor unit 1.

[0128] At this time, the movement of each indoor unit 1 is only affected by the second pipe section 32 connected to it, and will not be interfered with or affected by other indoor units 1, thereby facilitating the individual movement of each indoor unit 1 to improve the flexibility of movement of each indoor unit 1.

[0129] Among them, the connection between the first pipe segment 31 and the multiple second pipe segments 32 can be achieved by setting an air distributor at the other end of the first pipe segment 31, or by setting the other end of the first pipe segment 31 as a bell mouth and setting a fixing plate with multiple through holes on the bell mouth, wherein the multiple through holes are all connected to the first pipe segment 31, and one through hole is connected to one end of a second pipe segment 32.

[0130] In some embodiments, Fig.14 As shown, the mobile air conditioner also includes a power line 7 and a connecting line 8. The power line 7 is electrically connected to the outdoor unit 2 and is used for an external power supply. By connecting the power line 7 to the power supply, the outdoor unit 2 can be powered on so that the outdoor unit 2 can work.

[0131] Since the power line 7 is too long and difficult to organize, the power line 7 is usually set to be relatively short. At this time, in order to avoid setting a power line 7 for the indoor unit 1 separately, which causes the power line 7 to affect the moving range of the indoor unit 1, the connecting line 8 can be electrically connected to the indoor unit 1 and the outdoor unit 2. The outdoor unit 2 can be powered on to the indoor unit 1 through the connecting line 8, and the indoor unit 1 and the outdoor unit 2 can transmit signals to each other.

[0132] In this way, the current of the outdoor unit 2 can be transmitted to the indoor unit 1 through the connection line 8 for transmitting signals between the indoor unit 1 and the outdoor unit 2, so as to power the indoor unit 1, thereby facilitating the operation of the indoor unit 1. In this way, there is no need to separately set a power line 7 for the indoor unit 1, so that the power line 7 can be prevented from affecting the moving range of the indoor unit 1, thereby improving the flexibility of the movement of the indoor unit 1.

[0133] One end of the connecting wire 8 is connected to the circuit board of the outdoor unit 2, and the other end of the connecting wire 8 passes through the window of the house and is connected to the circuit board of the indoor unit 1. In addition, the indoor unit 1 is provided with a first control panel, which is electrically connected to the circuit board of the indoor unit 1, and the outdoor unit 2 is provided with a second control panel, which is electrically connected to the circuit board of the outdoor unit 2.

[0134] The first control panel can control the start and stop of the indoor fan 16 of the indoor unit 1, the setting of the indoor temperature, the air volume of the indoor unit 1, etc., and can also send a signal to the outdoor unit 2 to control the outdoor unit 2. The second control panel can control the start and stop of the outdoor unit 2, etc., and can also send a signal to the indoor unit 1 to control the indoor unit 1.

[0135] It should be noted that the connection line 8 can transmit both current and network signals. For example, the connection line 8 can be a coaxial cable.

[0136] On this basis, in order to prevent the connecting line 8 from affecting the moving range of the indoor unit 1, the length of the connecting line 8 can be made greater than or equal to the maximum length of the first air duct 3. The maximum length of the first air duct 3 refers to the length of the first air duct 3 when the first air duct 3 is stretched into a straight line and cannot be stretched any further.

[0137] In this way, within the maximum length range of the first air duct 3 , the movement of the indoor unit 1 will not be restricted by the connecting line 8 , thereby ensuring the movement range of the indoor unit 1 .

[0138] At this time, when the indoor unit 1 is placed closer to the outdoor unit 2, the first air duct 3 is not the longest, and the connecting line 8 will be redundant. In order to avoid the redundant part of the connecting line 8 being scattered on the ground and causing the connecting line 8 to be messy, such as Fig.14 As shown, the mobile air conditioner further comprises a wire take-up device 9 . The wire take-up device 9 is arranged on the first housing 11 ; in the case where the connecting wire 8 has redundancy, the redundant part of the connecting wire 8 is wound around the wire take-up device 9 .

[0139] By collecting the redundant parts of the connecting wires 8 through the wire take-up device 9, the connecting wires 8 can be arranged more neatly, thereby preventing the connecting wires 8 from being scattered and causing damage to the connecting wires 8.

[0140] The wire take-up device 9 may be a wire winding drum of model HY-052, or a wire winding device of model HY-061, etc.
