The present application provides a volute assembly 100. As shown in Figs. 1, 2 and 3, the volute assembly 100 includes a volute cover 200. The volute cover 200 includes a top plate 210 provided with a water diversion groove 220 extending along a length direction of the top plate 210. The water diversion groove 220 includes a bottom wall 221 and a first side wall 222 and a second side wall 223 both connected with the bottom wall 221. The first side wall 222 is opposite to the second side wall 223, and the water diversion groove 220 also includes a first reinforcing rib 224 connected with the bottom wall 221 and the first side wall 222, and the first reinforcing rib 224 is provided spaced from the second side wall 223.
When the air is discharged from the top of the movable air conditioner, the condensed water formed on the top plate 210 will converge to the water diversion groove 220, so as to prevent the condensed water from dispersing and flowing down to the interior of the movable air conditioner, and prevent the condensed water from damaging the internal components of the movable air conditioner, thereby improving the service life of the movable air conditioner.
Moreover, since the first reinforcing rib 224 is provided in the water diversion groove 220, the structural strength of the water diversion groove 220 and the volute cover 200 can be improved. At the same time, the first reinforcing rib 224 is spaced from the second side wall 223 for the condensed water to pass, so that the condensed water converged in the water diversion groove can flow out from one end of the water diversion groove, and prevent a large amount of condensed water from accumulating in the water diversion groove. That is, since the first reinforcing rib 224 is provided spaced from the second side wall 223, the structural strength of the water diversion groove 220 and the volute cover 200 can be strengthened without affecting the discharge of the condensed water in the water diversion groove 220.
Specifically, the water diversion groove 220 also includes a second reinforcing rib 225 connected with the bottom wall 221 and the second side wall 223 of the water diversion groove 220, and the second reinforcing rib 225 is spaced from the first side wall 222, thereby further strengthening the structural strength of the water diversion groove 220.
More specifically, the first reinforcing rib 224 is opposite to the second reinforcing rib 225, and the first reinforcing rib 224 and the second reinforcing rib 225 form a water passing groove therebetween. After flowing out of the water passing groove, the condensed water flows into a water receiving groove 610 of the middle partition plate 600 through a drainage structure of the volute assembly 100.

In other embodiments, the first reinforcing ribs 224 and the second reinforcing ribs 225 can also be provided at intervals as long as the condensed water can flow through.
The volute assembly 100 includes a first side plate 240 and a second side plate 250 respectively provided at both ends of the top plate 210. The bottom wall 221 of the water diversion groove 220 is inclined downward from the second side plate 250 toward the first side plate 240, that is, the bottom wall 221 is inclined along the length direction of the water diversion groove 220, which is more convenient to the flow of condensed water along the bottom wall 221 to one end of the water diversion groove 220 and prevent condensed water from accumulating on the bottom wall 221.
Further, the lower end of the first reinforcing rib 224 is inclined toward the first side plate 240. The first reinforcing rib 224 not only strengthens the structure of the water diversion groove 220, but also drain the condensed water. The condensed water flows into the bottom wall 221 of the water diversion groove 220 through the first reinforcing rib 224, and then flows into the end of the water diversion groove 220 along the inclined bottom wall 221. The lower end of the second reinforcing rib 225 can also be inclined toward the first side plate 240, and can also drain the water.
Further, the top plate 210 includes an upper extension plate 230 provided on one side of the water diversion groove 220, the upper extension plate 230 is connected with an upper edge of the first side wall 222, and a periphery of the upper extension plate 230 is convex upward with a water blocking rib 231. The indoor heat exchanger 700 is provided below the upper extension plate 230, and corresponds to an air inlet 500 of the movable air conditioner. an end of the upper extension plate 230 can be flush with an outer side of the indoor heat exchanger 700. A fan air duct is formed inside the volute assembly 100. The air enters the fan air duct through the indoor heat exchanger 700 and then enters the room through the indoor air outlet at the top. The condensed water formed at the top of the volute assembly 100 flows into the water diversion groove 220 along the upper extension plate 230 due to the blocking of the water blocking rib 231, and avoids to flow into the indoor heat exchanger 700 and be sucked into the fan air duct.
In an embodiment of the present application, the water blocking rib 231 includes a first water blocking rib 232 provided at a connection between the upper extension plate 230 and the first side wall 222. The first water blocking rib 232 is provided at one end of the water diversion groove 220 for draining water into the water diversion groove 220. The first water blocking rib 232 can prevent the condensed water from overflowing from the connection between the upper extension plate 230 and the first side wall 222 and drain the condensed water into the water diversion groove 220.
The volute assembly 100 also includes a volute 300 connected with the volute cover 200 to form a fan air duct. The volute 300 includes a front air duct plate 310, the upper end of the front air duct plate 310 is spaced from the second side wall 223, and is configured to form an air outlet 400 between the upper end of the front air duct plate 310 and the second side wall 223. The volute 300 is assembled with the volute cover 200 to form the volute assembly 100. The front air duct plate 310 is provided corresponding to the air inlet 500.

The middle partition plate 600 is provided with a water receiving groove 610, a water collecting groove 620 and a drainage groove 630. The indoor heat exchanger 700 is placed in the water receiving groove 610. The water receiving groove 610 is communicated with the water collecting groove 620, the water collecting groove 620 is communicated with the drainage groove 630. The outdoor heat exchanger is located below the drainage groove 630, and a plurality of drainage holes 631 are provided on the drainage groove 630. The condensed water in the water diversion groove 220 first flows into the water receiving groove 610 of the middle partition plate 600, then flows into the water collecting groove 620, then converges to the drainage groove 630, and flows into the outdoor heat exchanger through the drainage hole 631. The water collecting groove 620 includes a third side wall 621, a third side wall 621 and a fourth side wall 622.

The windshield plate 340 protruding downward can prevent the air from entering the gap between the windshield 320 and the drainage groove 630, thereby reducing air leakage, improving the utilization rate of the air and reducing the noise caused by air leakage.
As shown in Figs. 1 and 2, the volute cover 200 includes:

a top plate 210 provided with a water diversion groove 220 extending along a length direction of the top plate 210;
a first side plate 240 and a second side plate 250 respectively provided at both ends of the top plate 210; the first side plate 240 being provided with a first drainage structure 260 for draining the water overflowing from the water diversion groove 220; and/or, the second side plate 250 being provided with a second drainage structure 270 for draining water overflowed from the water diversion groove 220.

After the condensed water flows into the water diversion groove 220, it converges to the water collecting groove 620 of the middle partition plate 600 through the first drainage structure 260 and/or the second drainage structure 270. If the condensed water flows to the first side plate 240, it is drained through the first drainage structure 260. If the condensed water flows to the second side plate 250, it is drained through the second drainage structure 270. Through the drainage of the water diversion groove 220, the first drainage structure 260 and/or the second drainage structure 270, arbitrary flowing of the condensed water to the interior of the movable air conditioner is prevented, the damage to the internal components of the movable air conditioner is avoided, and the service life of the movable air conditioner is improved.
As shown in Fig. 4, the first side plate 240 is provided with a first wind wheel mounting hole 241 located below the water diversion groove 220, and the first drainage structure 260 is configured to guide water overflowed from the water diversion groove 220 to be away from the first wind wheel mounting hole 241. The volute 300 is connected with the volute cover 200 to form a fan air duct. A wind wheel is provided in the fan air duct, and one end of the wind wheel is provided in the first wind wheel mounting hole 241. The first drainage structure 260 drains the water to a place away from the first wind wheel mounting hole 241, avoiding the condensed water from being blown into the fan air duct from the first wind wheel mounting hole 241.
Specifically, as shown in Fig. 4, the first drainage structure 260 includes a first drainage rib 261 and a second drainage rib 263, the second drainage rib 263 is connected with a lower end of the first drainage rib 261, the first drainage rib 261 is provided on one side of the water diversion groove 220, and the second drainage rib 263 is extended obliquely to the other side of the water diversion groove 220. The first side plate 240 also includes a bending rib 262, which extends from one side wall of the water diversion groove 220 to the other side wall of the water diversion groove 220. A water diversion port 226 is formed between the bending rib 262 and the other side wall of the water diversion groove 220. The first drainage rib 261 is connected with the bending rib 262. The bending rib 262 of this embodiment is connected with the second side wall 223. In other embodiments, the bending rib 262 can be connected with the second side wall 223. The bending rib 262 makes the strength of the first drainage rib 261 higher, and makes the first drainage rib 261 closer to the first water leakage hole 243 located below. The upper ends of the first drainage rib 261 and the bending rib 262 can be flush with the upper end of the second side wall 223 to prevent a small amount of the condensed water from overflowing from the upper end of the first drainage rib 261 or from the upper end of the bending rib 262. In other embodiments, the first drainage rib 261 can also be directly connected with the first side wall 222 or with the second side wall 223, as long as the condensed water can be drained to the second drainage rib 263.
More specifically, a periphery of the first wind wheel mounting hole 241 is provided with a mounting annular boss 242, and a lower end of the second drainage rib 263 is connected with the mounting annular boss 242.

The first water leakage hole 243 is provided on a side of the second drainage rib 263 away from the first wind wheel mounting hole 241. One end of the third drainage rib 264 is connected with the second drainage rib 263, and the other end of the third drainage rib 264 is connected with the first water leakage hole 243, the third drainage rib 264 is configured to drain water to the first water leakage hole 243. The first water leakage hole 243 is provided at a connection between the volute 300 and the volute cover 200, which not only drains, but also strengthens the sealing of the volute assembly 100 and prevents air leakage. The third drainage rib 264 may include a third inclined rib and a third vertical rib, the third inclined rib is connected with the second drainage rib 263. The third vertical rib is docked with the first water leakage hole 243. The third inclined rib can drain the condensed water to a position away from the first wind wheel mounting hole 241. The third vertical rib can make the condensed water flow into the first water leakage hole 243 more smoothly. After flowing into the first water leakage hole 243, the condensed water directly falls into the middle partition plate 600, and then flows into the drainage groove 630, or flows into the drainage groove 630 after passing through the water collecting groove 620, and then flows into the outdoor heat exchanger from the drainage hole 631 of the drainage groove 630.
The bottom of the water diversion groove 220 is inclined downward from the second side plate 250 toward the first side plate 240. That is, most of the condensed water will flow to the first drainage structure 260 on the first side plate 240 along the bottom wall 221 of the condensed water, and only a small amount of condensed water will flow to the second drainage structure 270.
The first side plate 240 is provided with a water diversion port 226 communicated with the water diversion groove 220 to facilitate the condensed water flow to the first drainage structure 260 and then fall into the middle partition plate 600.

The second wind wheel mounting hole 251 is configured to mount the other end of the wind wheel. When the bottom wall 221 of the water diversion groove 220 is inclined to the first side plate 240, most of the condensed water will flow to the first drainage structure 260, but there may still be a small amount of condensed water flow to the second side plate 250. Therefore, the setting of the second drainage structure 270 prevents the condensed water from being sucked into the fan air duct from the second wind wheel mounting hole 251.
The second drainage structure 270 includes a fourth drainage rib 271 and a fifth drainage rib 272 connected with each other, the fourth drainage rib 271 and the fifth drainage rib 272 extend obliquely to two sides of the second wind wheel mounting hole 251 respectively.
