[0034] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the technical solution of the utility model is further described below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] In the embodiment of the present utility model, Figure 1-Figure 8 As shown, the volute for the duct machine comprises an upper volute 1 and a lower volute 2, a plurality of clips 3 are provided at the lower part of the upper volute 1, a plurality of buckles 4 are provided at the upper part of the lower volute 2, the plurality of clips 3 correspond to the plurality of buckles 4 one by one and are buckled with each other, so that the upper volute 1 and the lower volute 2 can be detachably connected in the vertical direction;

[0037] Among them, an upper overlapping edge is formed at the lower part of the upper volute 1, the distance between the root of the clip 3 and the upper overlapping edge is L, L>0㎝, and the angle between the clip 3 and the upper volute 1 is α, α>0°.

[0038] Specifically, in the embodiment of the utility model, after the upper volute 1 and the lower volute 2 are assembled, a cavity is formed therebetween for accommodating the wind wheel. A clip 3 and a buckle 4 are respectively arranged at corresponding positions of the upper volute 1 and the lower volute 2, and the clip 3 and the buckle 4 can be engaged with each other to realize the detachable connection between the upper volute 1 and the lower volute 2. In order to improve the reliability and sealing of the volute, as Figure 5 and Figure 8 As shown, this embodiment takes four clips 3 and four buckles 4 as an example, which are respectively located at (or close to) the four vertex corners of the upper volute 1 and the lower volute 2 .

[0039] In the embodiment of the utility model, the overlap between the upper volute 1 and the lower volute 2 is defined as the upper overlap edge. After the clip 3 is installed at the corresponding position of the upper volute 1, the root of the clip 3 is spaced from the upper overlap edge, and a spacing greater than 0 cm is formed therebetween, so as to increase the length of the clip 3 and stagger the root of the clip 3 from the upper overlap edge. On the one hand, the influence of the upper overlap edge on the clip 3 can be reduced during assembly, and effective avoidance can be achieved; on the other hand, the longer clip 3 can make the worker's stroke of moving the clip 3 smaller and more labor-saving. Of course, the end of the clip 3 protrudes below the upper overlap edge, and appropriately extending the end of the clip 3 can also shorten the stroke of the clip 3 during assembly.

[0040] In the embodiment of the utility model, the clip 3 is set at an angle to the vertical wall of the upper volute 1, so that the worker can engage the clip 3 with the buckle 4 by turning it at a smaller angle during assembly. After the assembly is completed, the clip 3 can be prevented from falling off automatically, and during disassembly, a certain thrust can be provided to make the clip 3 detach from the buckle 4, thereby improving the reliability and convenience during assembly and disassembly.

[0041] In this embodiment, the upper volute 1 and the lower volute 2 are detachably connected by the buckle 3 and the buckle 4, and the overall length of the clip 3 is increased, and the clip 3 is set at an angle with the upper volute 1, so that the upper volute 1 is installed on the lower volute 2 more conveniently and labor-savingly; after assembly, the integrity is reliable and the sealing is better; it is easy to assemble during production; and it is also easier to disassemble during after-sales maintenance.

[0042] like Figure 3 As shown, in one embodiment, the clip 3 is arranged to be opened outward relative to the upper volute 1. Specifically, in order to make the clip 3 and the upper volute 1 be arranged at an angle and to facilitate the installation of the clip 3 at the corresponding buckle 4, this embodiment defines that the clip 3 is arranged to be opened outward so that the clip 3 is exposed outside the upper volute 1, which, on the one hand, forms an assembly dead angle and, on the other hand, facilitates production and assembly.

[0043] like Figure 5-Figure 8 As shown, in one embodiment, the clip 3 and the buckle 4 are respectively provided with a matching step 301 and a through hole 401, and the step 301 is buckled with the buckle 4 along the through hole 401, so that the upper volute 1 is buckled with the lower volute 2. Specifically, in order to achieve the buckle connection between the clip 3 and the buckle 4, the present embodiment provides a step 301 on an end face of the clip 3 away from the upper volute 1, and a through hole 401 is provided at the buckle 4 along the up-down direction, and the corresponding step 301 cooperates with the through hole 401, so that the step 301 passes through the through hole 401 and is then buckled at the buckle 4, so that the clip 3 and the buckle 4 are buckled in the vertical direction, thereby connecting the upper volute 1 and the lower volute 2. It can be understood that since the end of the clip 3 is in a suspended state and is made of plastic material, it can use its own elastic force to achieve the buckle connection with the buckle 4; and it can be separated from the buckle 4 under the action of external force.

[0044] like Figure 5 , Figure 8 As shown, in one embodiment, the lower part of the upper volute 1 is provided with a plurality of slots 5, and the upper part of the lower volute 2 is provided with a plurality of tongues 6. In the vertical direction, the plurality of slots 5 and the plurality of tongues 6 are arranged one by one, and each tongue 6 can slide into each slot 5. Specifically, in order to position the travel of the clip 3 when assembling it, this embodiment is provided with slots 5 and tongues 6 at the corresponding parts of the upper volute 1 and the lower volute 2 (in this embodiment, the number of slots 5 and tongues 6 is equal to the number of clips 3 and buckles 4, and the two sets of data may not be equal in other embodiments, which will not be described in detail here). When the upper volute 1 and the lower volute 2 are assembled, the tongue 6 can slide into the slot 5 to guide; at the same time, the cooperation of the slot 5 and tongue 6 can also play a role in limiting and fixing the volute, so that the volute is assembled more tightly.

[0045] Preferably, the clip 3 and the slot 5 are arranged opposite to each other; the latch tongue 6 is arranged close to the buckle 4. This facilitates the clip 3 and the latch tongue 6 to perform corresponding actions synchronously to avoid obstruction.

[0046] In one embodiment, a lower overlapping edge is formed at the upper portion of the lower volute 2, and the upper overlapping edge and the lower overlapping edge are detachably connected.

[0047] Further, in one embodiment, if Fig. 9As shown, the lower lap edge is provided with a rim 7 along its length direction, and the rim 7 is a corner structure, which is used to wrap the upper lap edge. Specifically, in order to improve the sealing performance of the upper volute 1 and the lower volute 2, this embodiment adds a rim 7 at the lower lap edge of the lower volute 2, and the rim 7 is a corner structure bent upward, so as to wrap the upper lap edge of the upper volute 1, and play the role of assembling the volute, positioning, and sealing. Of course, the rim 7 can be set to be segmented.

[0048] Further, in one embodiment, if Fig.10 As shown, the upper lap edge and the lower lap edge are respectively provided with a matching clamping edge 8 and a notch 9, and in the vertical direction, the clamping edge 8 at least partially covers the lower lap edge through the notch 9. Specifically, in order to further improve the sealing performance of the volute, the present embodiment provides a matching clamping edge 8 and a notch 9 on the upper lap edge and the lower lap edge, respectively, the clamping edge 8 is a downwardly bent corner structure, and the notch 9 is located between the two adjacent wrapping edges 7, so as to cover the lower lap edge through the notch 9, thereby sealing the lap edge of the volute assembly.

[0049] like Figure 6 As shown, in one embodiment, the upper volute 1 is provided with a plurality of first reinforcing ribs 10; a plurality of second reinforcing ribs 11 are provided at the connection between the clip 3 and the upper volute 1 and / or between two adjacent clips 3. Specifically, in order to improve the stability of the upper volute 1, the present embodiment provides first reinforcing ribs 10 at the side wall of the air outlet of the upper volute 1 and at the left and right vertical walls of the upper volute 1 to strengthen the overall strength of the upper volute 1. Second reinforcing ribs 11 are provided at the connection between the clip 3 and the upper volute 1 and between two adjacent clips 3 on the left and right to strengthen the clip 3 and prevent the clip 3 from being damaged during assembly, disassembly, transportation, etc.

[0050] like Fig.11 As shown, the present embodiment further provides a duct machine, including an air duct mounting plate 12 and the above-mentioned volute. The specific structure of the volute refers to the above-mentioned embodiment. Since the present duct machine adopts all the technical solutions of the above-mentioned embodiment, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be described one by one here.

[0051] Specifically, the air duct mounting plate 12 in this embodiment is provided with coils one and two, a water level switch assembly, a wire clip, a motor assembly, etc., and the above-mentioned volute is detachably assembled on the air duct mounting plate 12.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
