Specific embodiment
The embodiment of the present invention is described below in detail, the example of the embodiment is shown in the drawings.Below with reference to
The embodiment of attached drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Spiral case 200 for range hood 1000 according to embodiments of the present invention can be applied in range hood 1000,
With reference to range hood 1000 overall structure to the spiral case 200 for range hood 1000 according to embodiments of the present invention into
Row is described in detail.
As shown in Figure 1, range hood 1000 can include：Smoke machine housing 100, spiral case 200 and wind wheel component 300.Smoke machine
Smoke machine is provided on housing 100 and recycles air port 101 and smoke machine exhaust outlet 102.Optionally, as shown in Figure 8 and Figure 9, smoke machine follows
Ring air outlet 101 is located at the front side of smoke machine exhaust outlet 102.
As shown in Figure 8 and Figure 9, spiral case 200 is at least partially disposed in smoke machine housing 100, wherein, optionally, spiral case
200 can be integrally provided in smoke machine housing 100, so as to which smoke machine housing 100 can preferably protect spiral case 200.
As depicted in figs. 1 and 2, in spiral case 200 there is spiral case air passage 210, spiral case air inlet 220 is provided on spiral case 200
The spiral case exhaust outlet 230 connected with smoke machine exhaust outlet 102, spiral case 200 includes set casing portion 240 and mobile shell portion 250, mobile
Shell portion 250 is relatively fixed shell portion 240 and can be moved between closed position A1 and open position A2.Wherein, at mobile shell portion 250
In closed position during A1, set casing portion 240 coordinates with mobile shell portion 250 and allows wind in spiral case air passage 210 from spiral case air draft
Mouth 230 is discharged.When being in the open position A2 in mobile shell portion 250, mobile shell portion 250 is relatively fixed shell portion 240 and staggers moving
Dynamic limited between shell portion 250 and set casing portion 240 recycles the spiral case that air port 101 connects with smoke machine and recycles air port 260, from
And the wind in spiral case air passage 210 is allowed to pass sequentially through spiral case recycles air port 260 and smoke machine recycles air port 101 and is discharged into room
It is interior.
Wherein, it is necessary to which explanation, when mobile shell portion 250 is in closed position A1, smoke machine exhaust outlet 102 is in open shape
State, the wind in spiral case air passage 210 can pass sequentially through spiral case exhaust outlet 230 and smoke machine exhaust outlet 102 is discharged into outdoor.Mobile shell portion
250 when being in the open position A2, and smoke machine exhaust outlet 102 is closed, optionally, as illustrated in figures 1 and 8, range hood
1000 can also include：End enclosure structure 800, end enclosure structure 800 are arranged for opening or close smoke machine exhaust outlet 102.It can be with
Understand, when needing to close smoke machine exhaust outlet 102, end enclosure structure 800 closes smoke machine exhaust outlet 102.Optionally, smoke machine is arranged
Air port 102 can be end cover structure, be provided with screw thread on end cover structure, be provided on the side wall of smoke machine exhaust outlet 102 and end cap
The corresponding screw thread of screw thread in structure, so as to which end cover structure can be tightened at smoke machine exhaust outlet 102.Such as Fig. 1, Fig. 8 and Fig. 9
Shown, smoke machine, which recycles air port 101, to be distributed along the length direction (left and right directions i.e. shown in Fig. 8) of smoke machine housing 100.Its

251 are connected, and the other end in mobile shell portion 250 is free end, and the free end in mobile shell portion 250 and the distance of wind wheel 301 are most
Closely.Between the abutting end 245 for moving the free end in shell portion 250 and the first affixed side wall portion 243 of affixed side wall portion 242 as a result,
It is in larger distance so that mobile shell portion 250, in open position A2, the aperture that spiral case recycles air port 260 is larger,
The air quantity in air port 260 can be ensured to recycle by spiral case, can also further ensure the work efficiency of range hood 1000.
Optionally, as shown in Fig. 5, Figure 10 and Figure 11, spiral case 200 can also include：First limiting device 400, the first limit
Position device 400 is arranged in set casing portion 240 and between wind wheel 301 and mobile shell portion 250.When mobile shell portion 250 is in
During the A2 of open position, the free end in mobile shell portion 250 can be with backstop on the first limiting device 400, and the first limiting device 400 can
To play the role of keeping apart mobile shell portion 250 and wind wheel 301 and can ensure to move between shell portion 250 and wind wheel 301
Minimum range thereby may be ensured that the normal work of range hood 1000.
Optionally, the first limiting device 400 can adsorb the mobile shell portion for being in the open position A2 by magnetic action
250.For example, mobile shell portion 250 can be irony part or electromagnetism part, the first limiting device 400 can be magnet, in mobile shell
When portion 250 is rotated from closed position A1 to open position A2, the first limiting device 400 can generate suction will mobile shell portion 250
Absorption is on it so that mobile shell portion 250 is maintained at open position A2.
Alternatively, optionally, the first limiting device 400 is limit protrusion, when being in the open position A2 in mobile shell portion 250,
