As shown in fig. 1, an embodiment of a range hood 10 includes a wind cabinet 100 and a volute 200.

In one embodiment, the wind cabinet 100 is provided with a first mounting location and the volute 200 is provided with a second mounting location that is matingly coupled to the first mounting location to secure the volute 200 within the wind cabinet 100.

Optionally, the first mounting position is a mounting hole on the wind cabinet 100, the second mounting position is a mounting hole on the scroll 200, and the fixing of the scroll 200 and the wind cabinet 100 can be achieved by inserting a fastener into the first mounting position and the second mounting position.

Optionally, the first assembly position is a screw hole, the second assembly position is a through hole, the fastener is a screw, and the screw sequentially penetrates through the second assembly position and the first assembly position, so that the volute 200 is fixedly connected with the wind cabinet 100; or the first assembling position is a through hole, the second assembling position is a screw hole, the fastening piece is a screw, and the screw sequentially penetrates through the first assembling position and the second assembling position so as to fixedly connect the volute 200 with the wind cabinet 100; or the first assembling position and the second assembling position are through holes, the fastening piece is a component matched with the screw and the nut, and the screw penetrates through the first assembling position and the second assembling position and is fixed through the nut; or the first assembling position and the second assembling position are both pin holes, the fastening piece is a pin, and the pin penetrates through the first assembling position and the second assembling position, so that the volute 200 is fixedly connected with the wind cabinet 100.

As discussed in the background of the invention, the volute 200 is difficult to install, most of which is because the first assembly location and the second assembly location are difficult to align, so that the volute 200 and the wind cabinet 100 cannot be fixedly connected together by the fastening member.

As shown in fig. 2 to 3, in one embodiment, the wind cabinet 100 is further provided with a first positioning member 110, the volute 200 is further provided with a second positioning member 210, and the second positioning member 210 is in positioning fit with the first positioning member 110, so that the second assembly position and the first assembly position are in a fittable state.

Specifically, in the above embodiment, the second assembling position and the first assembling position are both assembling holes, and the state that the second assembling position and the first assembling position are in a fittable state means that the second assembling position and the first assembling position are aligned, so that the scroll 200 and the wind cabinet 100 can be fixedly connected together by a fastener.

In the above range hood 10, after the scroll casing 200 is moved into the wind cabinet 100, the first positioning element 110 and the second positioning element 210 can be positioned and matched first, so as to position the scroll casing 200 and the wind cabinet 100, so that the second assembling position and the first assembling position are in a matched state, so that the second assembling position and the first assembling position can be quickly matched and connected, so as to fixedly install the scroll casing 200 in the wind cabinet 100, the operation is simple and rapid, the manual burden can be effectively reduced, and the production efficiency is improved.

As shown in fig. 2 to 4, in one embodiment, the first positioning element 110 is a sliding slot disposed on the inner side of the wind cabinet 100, and the second positioning element 210 is a sliding block disposed on the outer wall of the scroll casing 200, and the sliding block can slide into and be positioned and matched with the sliding slot. After the sliding block slides into the sliding groove, the sliding groove can limit the sliding block, so that the second assembling position and the first assembling position are in a matched state.

In another embodiment, the first positioning element 110 is a sliding block disposed inside the wind cabinet 100, and the second positioning element 210 is a sliding slot disposed on the outer wall of the volute 200, and the sliding block can slide into the sliding slot and be positioned and matched with the sliding slot.

In one embodiment, the sliding block is slidably engaged with the sliding groove to enable the scroll casing 200 to move in a predetermined direction relative to the wind cabinet 100, and when the scroll casing 200 moves in the predetermined direction, the scroll casing 200 can be located at a predetermined installation position, wherein when the scroll casing 200 is located at the predetermined installation position, the first installation position and the second installation position are in an engageable state. Because the slider can slide into the chute and is in sliding fit with the chute, the volute 200 and the wind cabinet 100 can slide relatively before being fixed, so that after the slider slides into the chute, the position of the volute 200 can be finely adjusted by moving the volute 200, the volute 200 is in a preset installation position, the first assembly position and the second assembly position are in a matched state, and when the first assembly position and the second assembly position are in a matched state, the inner side wall of the chute can play a limiting role in the slider, and the volute 200 is convenient to install.

Specifically, the spiral case 200 is configured to move into the wind cabinet 100 from bottom to top, and the sliding groove is configured to allow the sliding block to move up and down in the sliding groove. So, at spiral case 200 from up moving into the in-process of wind cabinet 100 down, the slider can slide into the spout, and the spout can carry on spacingly to the slider, in addition, after the slider slides into the spout, can finely tune the position of spiral case 200 through removing spiral case 200 to make spiral case 200 be in predetermineeing the mounted position.

As shown in fig. 2-4, the sliding slot further includes a first inner sidewall 111 and a second inner sidewall 112 spaced from and opposite to the first inner sidewall 111, and two sides of the sliding block are respectively in positioning fit with the first inner sidewall 111 and the second inner sidewall 112. So, after the slider slided into the spout, the first inside wall 111 and the second inside wall 112 of spout can be fixed a position the both sides of slider respectively to the restriction slider removes along the direction of first inside wall 111 to second inside wall 112. In addition, after the position of the scroll casing 200 is finely adjusted, the first assembly position and the second assembly position can be in a matched state, and the installation of the scroll casing 200 is facilitated.

Furthermore, the first inner side wall 111 includes a first positioning surface 111a and a first guiding surface 111b connected to the first positioning surface 111a, the second inner side wall 112 includes a second positioning surface 112a and a second guiding surface 112b connected to the second positioning surface 112a, the first positioning surface 111a is opposite to the second positioning surface 112a, the first guiding surface 111b is opposite to the second guiding surface 112b, two sides of the slider are respectively matched with the first positioning surface 111a and the second positioning surface 112a in a positioning manner, and two sides of the slider are respectively matched with the first guiding surface 111b and the second guiding surface 112b in a guiding manner. In the process that the sliding block slides into the sliding groove, the sliding block firstly passes through the first guide surface 111b and the second guide surface 112b and then passes through the first positioning surface 111a and the second positioning surface 112a, due to the guiding effect of the first guide surface 111b and the second guide surface 112b, the sliding block can slide into the sliding groove more conveniently, after the sliding block slides into the sliding groove, the sliding block is positioned by the first positioning surface 111a and the second positioning surface 112a, after the position of the volute 200 is finely adjusted, the first assembly position and the second assembly position can be in a matched state, and the volute 200 can be conveniently installed.

Specifically, the side of the first guide surface 111b away from the first positioning surface 111a and the side of the second guide surface 112b away from the second positioning surface 112a cooperate to form the slide inlet 113, and the distance between the first guide surface 111b and the second guide surface 112b increases from the side away from the slide inlet 113 to the direction close to the slide inlet 113. After the sliding block slides into the sliding groove, two sides of the sliding block can be just in contact with or close to the first positioning surface 111a and the second positioning surface 112a, so that the first positioning surface 111a and the second positioning surface 112a have a positioning effect on the sliding block. Since the distance between the first guide surface 111b and the second guide surface 112b increases from the side away from the slide entrance to the direction close to the slide entrance 113, the width of the slide entrance 113 can be made larger than that of the slider, so that the slider can slide into the chute more conveniently.

Note that, the two sides of the slider are in close contact with the first positioning surface 111a and the second positioning surface 112a means that the width of the slider is slightly smaller than the distance between the first positioning surface 111a and the second positioning surface 112a, but when the slider is slightly deviated toward the first positioning surface 111a or the second positioning surface 112a, the slider comes into contact with the first positioning surface 111a or the second positioning surface 112a, so that the first positioning surface 111a and the second positioning surface 112a play a role in positioning the slider. The width of the slider is slightly smaller than the distance between the first positioning surface 111a and the second positioning surface 112a, that is, the difference between the width of the slider and the distance between the first positioning surface 111a and the second positioning surface 112a may be 0.1mm to 0.6 mm.

As shown in fig. 2, in one embodiment, the range hood 10 further includes a bracket 220, the bracket 220 is disposed on an outer wall of the volute 200, the second positioning element 210 is disposed on the bracket 220, the volute 200 is disposed in the wind cabinet 100, and the bracket 220 is located between the volute 200 and the wind cabinet 100. By arranging the second positioning element 210 on the bracket 220, after the second positioning element 210 is matched with the first positioning element 110, the outer wall of the scroll casing 200 does not directly contact with the inner side of the wind cabinet 100, thereby preventing the scroll casing 200 or the wind cabinet 100 from being scratched in the installation process.

Specifically, the bracket 220 is similar to a shape like a Chinese character 'ji', the bracket 220 is fixed with the outer wall of the volute 200 by welding or screwing, and the second positioning element 210 is fixedly arranged on the side of the bracket 220 away from the volute 200.

In one embodiment, the wind cabinet 100 is provided with at least two first positioning members 110, the volute 200 is provided with at least two second positioning members 210, and the at least two first positioning members 110 are in one-to-one positioning fit with the at least two second positioning members 210. Through the one-to-one positioning matching of the at least two first positioning parts 110 and the at least two second positioning parts 210, the wind cabinet 100 can realize more precise positioning of the volute 200.

As shown in fig. 2 to 3, further, the wind cabinet 100 includes a first inner side 101 and a second inner side opposite to the first inner side 101, and among the at least two first positioning members 110, a first positioning member a disposed on the first inner side 101 and a first positioning member b disposed on the second inner side; the at least two second positioning members 210 include a second positioning member a and a second positioning member b, which are oppositely disposed on the outer wall of the scroll casing 200, the second positioning member a is in positioning fit with the first positioning member a, and the second positioning member b is in positioning fit with the first positioning member b. Because the first positioning piece a is opposite to the second positioning piece a in position, and the first positioning piece b is opposite to the second positioning piece b in position, when the second positioning piece a is in positioning fit with the first positioning piece a and the second positioning piece b is in positioning fit with the first positioning piece b, the rotation of the scroll casing 200 in the wind cabinet 100 can be limited, and thus the positioning accuracy of the wind cabinet 100 on the scroll casing 200 is further improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
