The second heat exchanger 121 is used as a condenser in a heating mode, and when humidification is required in a room, the humidifying water pump 200 is started, and condensed water in the water purifying area 133 is pumped to the humidifying part, and the humidifying part sprays the condensed water to the second heat exchanger 121. The second heat exchanger 121 heats and evaporates the condensed water into water vapor, and the water vapor enters the room to play a role of humidification in the process of heat exchange between the second heat exchanger 121 and the indoor air.

Alternatively, as shown in fig. 2, the humidifying part includes a spray pipe 210, a plurality of water spray holes 211 are provided on a pipe wall thereof, and the water spray holes 211 face the second heat exchanger 121. In the case where the humidifying water pump 200 is activated, the condensed water of the purified water zone 133 is pumped to the spraying pipe 210, and the spraying pipe 210 sprays the condensed water to the second heat exchanger 121 through the water spray hole 211.

In this embodiment, the plate surface of the second heat exchange section 1212 is vertically disposed, the plate surface of the first heat exchange section 1211 is disposed at an oblique angle to the plate surface of the second heat exchange section 1212, and a certain gap is provided between the first heat exchange section 1211 and the second heat exchange section 1212. The spray pipe 210 extends along the gap and sprays the condensed water toward the second heat exchange section 1212, evaporating the condensed water using heat of the second heat exchange section 1212.

Optionally, the length of the spray tube 210 coincides with the length of the second heat exchange section 1212. In this way, the spray tube 210 is prevented from being excessively long to interfere with other members, and the spray tube 210 can form a large spray area.

Alternatively, as shown in fig. 3, the humidifying part includes an atomizer 220, and an atomizing port of the atomizer 220 faces the second heat exchanger 121. The atomizer 220 is adopted to spray the condensed water to the second heat exchanger 121, so that the condensed water is more uniformly sprayed on the second heat exchanger 121 under the effect of the atomization function of the atomizer 220, and the effect of evaporating the condensed water by the second heat exchanger 121 is better.

Optionally, the second heat exchanger 121 is configured as a two-stage heat exchanger, comprising a first heat exchange section 1211 and a second heat exchange section 1212. Wherein the second heat exchange section 1212 is disposed adjacent to and below the first heat exchange section 1211; and, the atomizing port sprays water mist to both the first heat exchange section 1211 and the second heat exchange section 1212.

Optionally, the humidifying water pump 200 is disposed in the first chamber 110 or the second chamber 120, the water inlet end of which is connected to the water purifying area 133, and the water outlet end of which is connected to the water inlet of the atomizer 220.

Illustratively, the humidifying water pump 200 is disposed in the first compartment 110, and the water outlet end of the humidifying water pump 200 is provided with a connecting pipe extending from the first compartment 110 to the second compartment 120 and communicating with the water inlet of the atomizer 220.

In some embodiments, as shown in fig. 5, a middle barrier 400 is positioned between the first heat exchanger 113 and the second heat exchanger 121, including a water collection area 410 and a drainage area 420; wherein, the water collecting area 410 corresponds to the second heat exchanger 121 and is used for receiving condensed water thereof; the drain region 420 communicates with the water collecting region 410, and the drain region 420 drains condensed water to the first heat exchanger 113 through a drain.

In the present embodiment, the first heat exchanger 113 serves as a condenser and the second heat exchanger 121 serves as an evaporator in the cooling mode, and condensed water generated when the second heat exchanger 121 exchanges heat is collected to the water collection area 410. The condensed water in the water collecting area 410 then flows to the water draining area 420, and finally the water draining area 420 drains the condensed water to the first heat exchanger 113 through the water draining part, and exchanges heat with the first heat exchanger 113 with a higher temperature by using the condensed water with a lower temperature, so that the heat exchange efficiency of the first heat exchanger 113 serving as a condenser is improved.

Alternatively, the drainage area 420 corresponds to the first heat exchanger 113, and the drainage part includes a plurality of drainage holes 421, and the plurality of drainage holes 421 are disposed in the drainage area 420 and all face the first heat exchanger 113.

In the present embodiment, the drain region 420 is located above the first heat exchanger 113, and the drain hole 421 is disposed along the extending direction of the first heat exchanger 113. The condensed water of the water collecting region 410 flows to the water discharge region 420, and the condensed water of the water discharge region 420 flows to the first heat exchanger 113 through the plurality of water discharge holes 421.

Alternatively, the drain hole 421 is formed with a protrusion at its periphery upward, and the protrusion is provided with a notch.

In the present embodiment, when the water level of the condensed water in the drain area 420 is higher than the notch on the protrusion, the condensed water flows to the first heat exchanger 113 through the drain hole 421. And the tension of water can be broken under the effect of the notch, thereby being beneficial to smooth circulation of condensed water.

Optionally, the level of the drain region 420 is lower than the level of the water collection region 410. The condensed water in the water collecting area 410 is facilitated to flow to the water draining area 420 by the height difference.

Optionally, the middle partition 400 further includes a straight drainage area 430, the straight drainage area 430 is communicated with the drainage area 420, and condensed water which is not drained to the first heat exchanger 113 in the drainage area 420 is drained to the straight drainage area 430; and, the in-line area 430 communicates with the outside of the cabinet 100.

In the present embodiment, when the amount of the condensed water is large, it is difficult to timely drain the condensed water only through the drain hole 421. At this time, the condensed water not discharged to the first heat exchanger 113 flows to the straight drain region 430, and the condensed water of the straight drain region 430 may be directly discharged to the outside of the cabinet 100.

Optionally, the level of the in-line zone 430 is lower than the drainage zone 420. The condensed water of the drainage area 420 is facilitated to flow to the straight drainage area 430 by the height difference.

Optionally, the drainage area 420 communicates with the in-line area 430 through a slope. The condensed water of the drainage area 420 smoothly flows to the straight drainage area 430 under the action of the inclined surface.

Optionally, the water collection area 410 is provided with transverse ribs 411, the transverse ribs 411 being used to support the second heat exchanger 121. Here, the positions of the lateral ribs 411 correspond to the bottom of the second heat exchanger 121, and the number of the lateral ribs 411 may be plural, thereby supporting the bottom of the second heat exchanger 121.

Optionally, an upper volute is further disposed within the housing 100, the upper volute being located above the middle partition 400, the upper volute comprising an upper housing and a lower housing 440. The lower housing 440 and the upper housing define an air channel, and an air channel inlet of the air channel corresponds to the water collecting area 410, so that condensed water in the air channel flows to the water collecting area 410. A second fan is provided in the air duct of the upper volute, and condensed water in the air duct can flow from the air duct inlet to the water collection area 410.

Alternatively, the lower housing 440 is integrally formed with the middle partition 400, and a portion of the lower housing 440 constituting the air duct inlet is connected to the water collection area 410. Thus, the middle barrier 400 and the lower case 440 divide the interior of the cabinet 100 into the first compartment 110 and the second compartment 120.

In some embodiments, the mobile air conditioner further includes a flushing water pump 230, wherein a water inlet end of the flushing water pump 230 is connected to the water purifying area 133, and a water outlet end of the flushing water pump is used for being connected to the in-line area 430; the rinse water pump 230 may pump the condensed water in the purified water zone 133 to the in-line zone 430 to rinse the in-line zone 430.

In this embodiment, the condensed water generated during the heat exchange of the first heat exchanger 113 is filtered and collected in the water purifying area 133, so that the quality of the condensed water in the water purifying area 133 is better. Condensed water generated during heat exchange of the second heat exchanger 121 is collected in the straight-drain region 430, and as the quality of the condensed water in the straight-drain region 430 which is not filtered is poor, more impurities are attached in the straight-drain region 430. When the in-line area 430 needs to be flushed, the flushing water pump 230 is started to pump the condensed water in the clean water area 133 to the in-line area 430, so that the in-line area 430 is flushed with clean condensed water.

Alternatively, as shown in fig. 5, the in-line area 430 discharges condensed water to the outside of the casing 100 through the in-line discharge 431; the water outlet end of the flushing water pump 230 is provided with a flushing pipe 231, and the flushing pipe 231 is used for communicating with the straight discharge port 431. When the flushing water pump 230 is started, the condensed water in the water purifying area 133 flows from the in-line outlet 431 to the in-line outlet 430 through the water pipe 231, and thus flushing is performed.

Optionally, the in-line outlet 431 is provided with a pipe connection for connecting the flushing pipe 231. The coupler is adapted to the end of the flush tube 231.

Alternatively, the in-line outlet 431 protrudes outside the casing 100; the water flushing pipe 231 is disposed outside the casing 100, and has a first end connected to the water outlet end of the flushing pump 230 and a second end for communicating with the in-line outlet 431. In this way, the user can conveniently connect the flushing pipe 231 to the straight discharge port 431 at the outside of the cabinet 100.

Optionally, a hook is provided on the outside of the casing 100 for hanging the flush tube 231. In this way, the flush tube 231 can be hung outside the casing 100 by the hook.

Optionally, the mobile air conditioner further includes a prompting device configured to send out a flushing prompt after the mobile air conditioner operates for a set time, so as to remind a user to connect the flushing pipe 231 to the in-line outlet 431.

Illustratively, the mobile air conditioner is determined to be dirty in the in-line area 430 and needs to be flushed after running for 500 hours, and the prompting device lights a yellow lamp to prompt the user. After the user sees the yellow light on, the flush tube 231 is connected to the in-line outlet 431 to flush the in-line area 430.

Optionally, the septum 400 further includes a drainage area 420. The drainage area 420 is communicated with the straight drainage area 430, and the drainage area 420 drains water to the first heat exchanger 113 through the drainage holes 421; the condensed water pumped to the straight drain area 430 by the washing water pump 230 may flow to and wash the drain area 420.

In the present embodiment, the drain hole 421 has a small diameter, and is likely to be clogged when the quality of the condensed water in the second heat exchanger 121 is poor. When the filth blockage occurs, the flushing water pump 230 is started to pump the condensed water in the water purifying area 133 to the direct drainage area 430, and the condensed water in the direct drainage area 430 flows to the drainage area 420, so that the drainage hole 421 is flushed with the clean condensed water. The washed condensed water flows to the first heat exchanger 113 along the drain hole 421, and the part of the condensed water and the condensed water newly generated by the first heat exchanger 113 flow to the sewage area 131 on the bottom plate 130, and finally flows to the water purifying area 133 after being filtered.

Optionally, the level of the in-line area 430 is lower than that of the drainage area 420, and the condensed water pumped to the in-line area 430 by the flushing water pump 230 overflows to the drainage area 420.

Optionally, as shown in fig. 4, the chassis 130 of the casing 100 is further provided with a sewage area 131, and the sewage area 131 is communicated with the water purifying area 133 through the water purifying device 132; the condensed water of the first heat exchanger 113 is first collected in the sewage area 131, and then filtered by the water purifying device 132 to flow to the water purifying area 133.

Alternatively, the condensed water in the sewage area 131 may be discharged to the outside of the cabinet 100 through a pipe. In this way, in the case that the water level of the water purifying zone 133 is high, the condensed water of the sewage zone 131 can be directly discharged to the outside.

In some embodiments, as shown in fig. 7-9, the first air outlet 112 is communicated with the outside of the room through an air outlet pipe, and the mobile air conditioner further comprises an air inlet assembly. The air inlet assembly is disposed at the first air inlet 111 and includes a first housing 310 or a second housing 320; the first housing 310 is provided with a first communication port 311, and the first communication port 311 is used for being communicated with the outside through an air inlet pipe; the second housing 320 is provided with a second communication port 321, and the second communication port 321 is used for communicating with the indoor space; when the first housing 310 is installed at the first air inlet 111, the first heat exchanger 113 exchanges heat with outdoor air; when the second housing 320 is installed at the first air inlet 111, the first heat exchanger 113 exchanges heat with indoor air.

In the present embodiment, the mobile air conditioner can realize switching between the single duct mode and the dual duct mode by selectively installing the first casing 310 or the second casing 320. In case that the first heat exchanger 113 and the outdoor air are required to exchange heat, the first cover 310 is installed at the first air inlet 111, and then the air inlet duct is connected at the first communication port 311.
