As shown in fig. 2, the interior of the cabinet 100 is partitioned into a first compartment 101 and a second compartment 102 by a partition 400, and the first compartment 101 is located above the second compartment 102. The first compartment 101 is provided with a first air inlet 103 and a first air outlet 104, and the second compartment 102 is provided with a second air inlet and a second air outlet. The heat exchange assembly includes a first heat exchanger 110 and a second heat exchanger 120, the first heat exchanger 110 is disposed in the first compartment 101, and the second heat exchanger 120 is disposed in the second compartment 102. The fan assembly includes a first fan disposed within the first compartment 101 and a second fan disposed within the second compartment 102. The first fan is disposed in the volute assembly, and the first heat exchanger 110 is disposed between the volute inlet of the volute assembly and the first air inlet 103. Under the action of the first fan, indoor air enters the first compartment 101 from the first air inlet 103, exchanges heat with the first heat exchanger 110, and leaves the first compartment 101 from the first air outlet 104; the outdoor air enters the second compartment 102 from the second air inlet under the action of the second fan, exchanges heat with the second heat exchanger 120, and leaves the second compartment 102 from the second air outlet. Here, the air conditioner includes a mobile air conditioner.

The refrigerant circulation system of the mobile air conditioner is composed of at least a compressor, a first heat exchanger 110, a throttling device and a second heat exchanger 120. In the refrigeration mode, the circulation flow direction of the refrigerant circulation system is as follows: a compressor, a second heat exchanger 120, a throttling device, a first heat exchanger 110 and a compressor, where the first heat exchanger 110 acts as an evaporator and the second heat exchanger 120 acts as a condenser. In the heating mode, the circulation flow direction of the refrigerant circulation system is as follows: a compressor, a first heat exchanger 110, a throttling device, a second heat exchanger 120 and a compressor, wherein the first heat exchanger 110 acts as a condenser and the second heat exchanger 120 acts as an evaporator.

In this embodiment, the air conditioner further includes an air duct assembly including an air inlet duct 130 and an air outlet duct 140. As shown in fig. 1, the first end of the air inlet pipe 130 is connected to the second air inlet, and the second end is used for being connected to the outdoor environment. The first end of the air outlet pipe 140 is connected to the second air outlet, and the second end is used for being connected to the outdoor environment. The outdoor air enters the second compartment 102 through the air inlet pipe 130 under the action of the second fan, exchanges heat with the second heat exchanger 120, and returns to the outdoor environment from the air outlet pipe 140.

In some embodiments, the volute assembly includes an upper volute 200 and a lower volute 220. As shown in fig. 3 and 4, the first end of the upper volute 200 is provided with a water receiving tank 210, and the water receiving tank 210 is provided with a first drain hole 214; the first end of the lower scroll 220 is provided with a drain groove 221, and the drain groove 221 is provided with a second drain hole 225; the first end of the upper scroll 200 is butted with the first end of the lower scroll 220, and the bottom surface of the water receiving tank 210 is butted with the notch of the water draining tank 221; the condensed water generated at the first end of the upper scroll 200 flows toward the water receiving tank 210 and is discharged through the first drain hole 214, the drain tank 221, and the second drain hole 225 in sequence.

In this embodiment, the air conditioner circulates cool air in the volute assembly under the cooling condition. Because the inner side wall and the outer side wall of the volute assembly have a temperature difference, and the temperature outside the volute assembly is relatively high, condensed water can be generated on the outer side wall of the volute assembly. At this time, the condensed water on the outer sidewall of the first end of the upper scroll 200 flows into the water receiving tank 210, and the condensed water enters the drain tank 221 through the first drain hole 214, and then the condensed water in the drain tank 221 is drained through the second drain hole 225. In this way, the condensed water generated from the upper scroll 200 can be rapidly collected and discharged.

Alternatively, the water receiving tank 210 is disposed at the lower side of the first end of the upper scroll 200; the drain groove 221 is disposed at an upper side of the first end of the lower scroll 220, and a notch of the drain groove 221 faces a bottom surface of the water receiving groove 210. Thus, after the upper scroll 200 and the lower scroll 220 are butted, the bottom surface of the water receiving tank 210 covers the notch of the water discharge tank 221. At this time, the notch of the water receiving tank 210 is opened for receiving the condensed water generated from the side wall of the first end of the upper scroll 200, and the drain tank 221 forms a relatively closed condensed water drain passage.

Alternatively, as shown in fig. 5, the drain groove 221 includes a lower mounting section 224, a first drain section 222, and a second drain section 223. Wherein the lower mounting section 224 is for mounting a bearing; the first drainage section 222 is connected to one side of the lower mounting section 224; the second drain section 223 is connected to the other side of the lower mounting section 224.

In this embodiment, the first fan is a cross-flow fan, and the bearing of the first end of the first fan is mounted in the lower mounting section 224. As the cold air circulates within the volute assembly, the bearings also produce condensate that drops directly into the lower mounting section 224.

Alternatively, the bottom of the lower mounting section 224 has a lower level than the bottoms of the first and second drain sections 222, 223.

In this embodiment, a support structure is provided in the lower mounting section 224 for supporting the bearing. And, under the action of the supporting structure, a certain distance is arranged between the bearing and the bottom of the groove of the lower mounting section 224. Preferably, the bottoms of the first and second drain sections 222 and 223 have the same horizontal height, and the second drain hole 225 is formed at the bottom of the lower mounting section 224. Thus, the condensed water of the first and second drain sections 222 and 223 flows to the lower mounting section 224 by gravity and is finally discharged through the second drain hole 225.

Optionally, the water receiving tank 210 includes an upper mounting section 213, a first water receiving section 211, and a second water receiving section 212. Wherein, the bottom surface of the upper mounting section 213 faces the notch of the lower mounting section 224, and the bottom surface of the upper mounting section and the lower mounting section 224 can enclose a mounting space of the bearing. The first water receiving section 211 is connected to one side of the upper mounting section 213, and its bottom surface covers the notch of the first water draining section 222; the second water receiving section 212 is connected to the other side of the upper mounting section 213, and its bottom surface covers the notch of the second water discharging section 223. The two first drain holes 214 are respectively disposed on the first water receiving section 211 and the second water receiving section 212.

In the present embodiment, the bottoms of the first and second water receiving sections 211 and 212 have the same horizontal height, and the bottom surface of the upper mounting section 213 is constructed in a dome shape. After the upper scroll 200 and the lower scroll 220 are butted, the bottom surface of the upper mounting section 213 and the lower mounting section 224 define a mounting space for the bearing. The condensed water received by the upper mounting section 213 flows into the first water receiving section 211 or the second water receiving section 212, the condensed water received by the first water receiving section 211 flows into the first water discharging section 222 through the corresponding first water discharging hole 214, and the condensed water received by the second water receiving section 212 flows into the second water discharging section 223 through the corresponding first water discharging hole 214. The condensed water of the first and second drain sections 222 and 223 flows down the mounting section 224 and is finally discharged through the second drain hole 225.

Alternatively, as shown in fig. 4, the lower scroll 220 is provided with a first drainage plate 230, a head end of the first drainage plate 230 is located at an outlet of the second drainage hole 225, and a tail end of the first drainage plate 230 extends obliquely downward in a direction away from the lower scroll 220 for guiding condensed water to be discharged.

In this embodiment, a water collecting region 410 is provided at one side of the middle partition 400, and the water collecting region 410 is located below the end of the first drainage plate 230. Thus, the condensed water in the drain groove 221 flows into the water collecting region 410 from the second drain hole 225 and the first drain plate 230 in this order.

Optionally, a third drain hole 226 is formed on a side wall of the lower mounting section 224, and a level of the third drain hole 226 is higher than a level of the second drain hole 225. In this way, when the water level of the condensed water in the drain groove 221 is higher than the third drain hole 226, drainage is performed through both the second drain hole 225 and the third drain hole 226.

Optionally, the lower volute 220 is further provided with a second drainage plate 240, and the second drainage plate 240 is located below the third drainage hole 226, and the end of the second drainage plate extends downward and obliquely in a direction away from the lower volute 220; the condensed water may flow to the second drain plate 240 through the third drain holes 226 and be guided to be discharged by the second drain plate 240.

Optionally, the outer periphery of the second flow guiding plate 240 has a peripheral edge, and the second flow guiding plate 240 is disposed at the bottom of the lower volute 220. In this way, the second drainage plate 240 can both receive the condensed water generated from the side wall of the first end of the lower scroll 220 and receive and guide the condensed water discharged from the third drain hole 226 to circulate.

In this embodiment, a water collecting region 410 is provided at one side of the middle partition 400, and the water collecting region 410 is located below the end of the second drainage plate 240. The condensed water flows into the water collecting region 410 along the second flow guiding plate 240 by gravity. Preferably, the second drainage plate 240 gradually widens from the head end to the tail end. In this way, the condensed water smoothly flows into the water collecting area 410 in the case of a large amount of water.

In combination with the above embodiments, the flow direction of the condensed water at the first end of the volute component is:

The condensed water on the side wall of the first end of the upper volute 200 flows to the water receiving groove 210, and the condensed water flowing into the upper mounting section 213 continuously flows into the first water receiving section 211 or the second water receiving section 212, the condensed water received by the first water receiving section 211 flows into the first water discharging section 222 through the corresponding first water discharging hole 214, and the condensed water received by the second water receiving section 212 flows into the second water discharging section 223 through the corresponding first water discharging hole 214. The condensed water of the first and second water discharge sections 222 and 223 flows to the lower mounting section 224.

In the case where the water level in the installation section is low, the condensed water in the lower installation section 224 flows only from the second drain holes 225 to the first drain plate 230, and the first drain plate 230 guides the condensed water to flow into the water collecting region 410 of the middle partition 400. In the case that the water level in the installation section is higher than the third drain holes 226, the condensed water in the lower installation section 224 simultaneously flows from the third drain holes 226 to the second drain plate 240, and the second drain plate 240 guides the condensed water to flow into the water collecting region 410 of the middle partition 400.

Optionally, a fourth drain hole is provided in the water collecting region 410, and the fourth drain hole is located above the second heat exchanger 120. In this way, the condensed water in the water collecting area 410 may flow to the second heat exchanger 120 through the fourth drain hole, thereby exchanging heat with the second heat exchanger 120 using the condensed water.

Optionally, a straight drain is provided in the water collection region 410, the straight drain extending outside of the housing 100. The user can adopt the external straight-line outlet of water pipe. In this way, the condensed water in the water collecting area 410 can be discharged to the outside through the straight drain.
