[0037] The utility model discloses a kind of range hood, please refer to Figures 1 to 4 And Figures 10 to 14 The range hood of the utility model includes shell 1 and air curtain assembly 2;Shell 1 has top plate 11, cover plate 12 and the electric control cavity 13 between top plate 11 and cover plate 12, the both sides of top plate 11 are equipped with air curtain air outlet 111, top plate 11 is equipped with air curtain support 112 corresponding with air curtain air outlet 111, cover plate 12 is equipped with access hole 121 and the access cover 14 covering access hole 121, access hole 121 is communicated with electric control cavity 13, shell 1 is also equipped with the air inlet channel communicated with electric control cavity 13;Air curtain assembly 2 quantity is two, two air curtain assemblies 2 are arranged in electric control cavity 13 and the air outlet end is aligned with corresponding side air curtain air outlet 111, the left end of left air curtain assembly 2 is connected with air curtain support 112, and the right end is connected with air curtain support 112 by screw;The right end of right air curtain assembly 2 is connected with air curtain support 112, and the left end is connected with air curtain support 112 by screw, the downward projection of access hole 121 covers the right end of left air curtain assembly 2 and the left end of right air curtain assembly 2.

[0038] In the embodiment, air curtain air outlet 111 penetrates the upper surface and the lower surface of top plate 11, that is, the space below top plate 11 is communicated with electric control cavity 13, air curtain assembly 2 is installed on the upper surface of top plate 11 and located at air curtain air outlet 111, when air curtain assembly 2 operates, external air enters electric control cavity 13, air curtain assembly 2 sucks the air in electric control cavity 13 and exhausts through air curtain air outlet 111, to form air curtain below air curtain air outlet 111.

[0039] The number of the air curtain outlets 111 can be two, and the two air curtain outlets 111 are arranged in left and right directions. The number of the air curtain assemblies 2 is two, and the two air curtain assemblies 2 are respectively arranged in the electric control cavity 13 corresponding to the two air curtain outlets 111. In this way, the number of the air curtains below the top plate 11 can be increased, so that the blocking effect on the oil fume can be improved.

[0040] The air curtain support 112 is arranged on the upper surface of the top plate 11, that is, in the electric control cavity 13, and the air curtain support 112 can support and fix the air curtain assembly 2.

[0041] The two air curtain assemblies 2 can be respectively defined as a left air curtain assembly and a right air curtain assembly, and the two air curtain supports 112 can be respectively defined as a left air curtain support and a right air curtain support.

[0042] When the left air curtain assembly is installed, the left air curtain assembly is first slid along the left air curtain support from right to left until the left end of the left air curtain assembly is clamped and fixed with the left end of the left air curtain support. After the clamping is in place, the right end of the left air curtain assembly is aligned with the right end of the left air curtain support. At this time, the right end of the left air curtain assembly can be connected with the left air curtain support through a screw.

[0043] When the right air curtain assembly is installed, the right air curtain assembly is first slid along the right air curtain support from left to right until the right end of the right air curtain assembly is clamped and fixed with the right end of the right air curtain support. After the clamping is in place, the left end of the right air curtain assembly is aligned with the left end of the right air curtain support. At this time, the left end of the right air curtain assembly can be connected with the right air curtain support through a screw.

[0044] After the two air curtain assemblies 2 are installed on the two air curtain supports 112, the ends of the two air curtain assemblies 2 close to each other are aligned with the access opening 121, that is, the right end of the left air curtain assembly and the left end of the right air curtain assembly are aligned with the access opening 121. Therefore, the screws for fixedly connecting the two air curtain assemblies 2 with the air curtain supports 112 are also aligned with the access opening 121.

[0045] The access cover 14 is detachably arranged on the access opening 121. When the air curtain assembly 2 needs to be disassembled, the access cover 14 can be opened to expose the access opening 121, so that the screws can be exposed through the access opening 121. Then, the worker can disassemble the screws through the access opening 121 to release the connection relationship between the two air curtain assemblies 2 and the air curtain supports 112. Then, the two air curtain assemblies 2 can be pulled out from the access opening 121 in the direction of the inclined upward direction in sequence. While the two air curtain assemblies 2 are pulled out, the clamping relationship between the two air curtain assemblies 2 and the air curtain supports 112 can be directly released. In this way, the convenience of disassembling and repairing the two air curtain assemblies 2 can be improved.

[0046] The smoke machine of the utility model, like Figure 14As shown, the air curtain support 112 is provided with an avoiding opening 1121 arranged along the length of the air curtain support 112, the air curtain support 112 is arranged on the top plate 11, and the avoiding opening 1121 avoids the air curtain outlet 111 on the corresponding side, and the air outlet end of the air curtain assembly 2 extends into the avoiding opening 1121 on the corresponding side and is aligned with the air curtain outlet 111 on the corresponding side.

[0047] The top plate 11 is provided with a raised portion formed on the upper plate surface of the top plate 11, and the lower plate surface of the top plate 11 is concavely provided with a cavity corresponding to the raised portion, and the air curtain outlet 111 is arranged in the cavity. The oil fume generated during cooking will flow towards the suction port of the range hood under the action of negative pressure formed at the suction port, part of the oil fume will hit the top plate 11 and flow forward under the action of the wall attachment effect, and the oil fume will be blocked from flowing when it reaches the cavity, thereby interrupting the tendency of the oil fume to continue flowing forward, so that the oil fume can be more timely and fully blocked by the air curtain and blown downward. In this way, the oil fume can be prevented from adhering to the air curtain assembly 2 after flowing into the air curtain outlet 111, so as to ensure the operation effect of the air curtain assembly 2.

[0048] The air curtain support 112 can avoid the raised portion through the avoiding opening 1121 and be connected with the top plate 11 to realize stable installation of the air curtain support 112 on the top plate 11, and the avoiding opening 1121 can also communicate the air curtain assembly 2 with the air curtain outlet 111, so that the airflow blown by the air curtain assembly 2 can flow to the air curtain outlet 111 through the avoiding opening 1121, and then flow to the lower part of the top plate 11 to form an air curtain through the air curtain outlet 111. By arranging the avoiding opening 1121 on the air curtain support 112, the installation of the air curtain support 112 on the raised portion of the top plate 11 can be avoided, thereby improving the overall installation convenience of the air curtain assembly 2.

[0049] The raised portion extends along the length direction of the top plate 11, and the lower plate surface of the top plate 11 is formed with a long strip-shaped cavity corresponding to the raised portion. The two air curtain outlets 111 are both arranged in the cavity and are arranged at intervals along the length direction of the cavity.

[0050] The range hood of the utility model, such as Figure 14 As shown, the avoiding opening 1121 of the air curtain support 112 is provided with a vertical wall 1122 on both side edges, the left side of the vertical wall 1122 of the left air curtain support 112 is provided with a clamping plate 1123 extending into the avoiding opening 1121, and the left end of the left air curtain assembly 2 is clamped with the clamping plate 1123; the right side of the vertical wall 1122 of the right air curtain support 112 is provided with a clamping plate 1123 extending into the avoiding opening 1121, and the right end of the right air curtain assembly 2 is clamped with the clamping plate 1123.

[0051] The bottom side edge of the vertical wall 1122 is connected to the two long side edges of the avoiding opening 1121, and the clamping plate 1123 is connected to the top side edge of the vertical wall 1122.

[0052] For the left air curtain support, the clamping plate 1123 is close to the left end of the left air curtain support. When the left air curtain assembly is installed on the left air curtain support, the left end of the left air curtain assembly is clamped and fixed with the clamping plate 1123 of the left air curtain support.

[0053] For the right air curtain support, the clamping plate 1123 is close to the right end of the right air curtain support. When the right air curtain assembly is installed on the right air curtain support, the right end of the right air curtain assembly is clamped and fixed with the clamping plate 1123 of the right air curtain support.

[0054] The smoke machine of the utility model, such as Figure 12 As shown in the figure, the air curtain assembly 2 comprises a cyclone seat 21 and an air curtain fan 22, the cyclone seat 21 is provided with an air outlet channel 211 communicated with the air curtain air outlet 111, the air curtain fan 22 is arranged on the cyclone seat 21, the air outlet end of the air curtain fan 22 faces the air outlet channel 211, the bottom of the cyclone seat 21 is provided with a first buckle 212 matched with the clamping plate 1123 of the corresponding side, and the first buckle 212 is clamped with the clamping plate 1123.

[0055] The cyclone seat 21 and the air curtain fan 22 are fixedly connected together in advance and then integrally installed on the air curtain support 112. When the air curtain assembly 2 is clamped with the air curtain support 112, the first buckle 212 on the cyclone seat 21 is clamped with the clamping plate 1123 on the air curtain support 112. The two clamping plates 1123 are arranged side by side, the number and position of the first buckles 212 correspond to the clamping plates 1123, and the two first buckles 212 are clamped on the two clamping plates 1123 respectively.

[0056] The smoke machine of the utility model, such as Figure 14 As shown in the figure, the clamping plate 1123 forms an included angle a with the horizontal plane, and 0° < a < 10°. The distance between the two clamping plates 1123 and the upper surface of the top plate 11 decreases from the side where the two clamping plates 1123 are close to each other to the side where the two clamping plates 1123 are far away from each other, so that the side where the two clamping plates 1123 are close to each other can be slightly tilted upward, thereby guiding the first buckle 212, and the first buckle 212 can be clamped and fixed with the clamping plate 1123 more quickly and conveniently.

[0057] The smoke machine of the utility model, such as Figure 14 As shown in the figure, the width of one end of the clamping plate 1123 facing the first buckle 212 clamped therewith is a, and the width of the other end is b, and 0 < a < b.

[0058] The first buckle 212 of the cyclone seat 21 of the left air curtain assembly is clamped on the clamping plate 1123 from the right end of the clamping plate 1123, and the first buckle 212 of the cyclone seat 21 of the right air curtain assembly is clamped on the clamping plate 1123 from the left end of the clamping plate 1123.

[0059] The width of the clamping plate 1123 increases from the end clamped with the first buckle 212 to the end away from the first buckle 212, so that the distance between the two clamping plates 1123 decreases from the end clamped with the first buckle 212 to the end away from the first buckle 212, thereby guiding the part of the cyclone seat 21 clamped between the two clamping plates 1123 and improving the convenience of the cooperation between the cyclone seat 21 and the two clamping plates 1123.

[0060] Specifically, the width of the clamping plate 1123 of the left air curtain support increases from right to left, so that the distance between the two clamping plates 1123 of the left air curtain support decreases from right to left, thereby guiding the cyclone seat 21 of the left air curtain assembly sliding from right to left and improving the convenience of the cooperation between the cyclone seat 21 and the two clamping plates 1123.

[0061] The width of the clamping plate 1123 of the right air curtain support increases from left to right, so that the distance between the two clamping plates 1123 of the right air curtain support decreases from left to right, thereby guiding the cyclone seat 21 of the right air curtain assembly sliding from left to right and improving the convenience of the cooperation between the cyclone seat 21 and the two clamping plates 1123.

[0062] The smoke machine of the utility model, the bottom of the cyclone seat 21 is mirror imaged with two groups of first buckles 212 on both ends, so that the air curtain support 112 and the cyclone seat 21 of the two groups of air curtain assemblies 2 are general parts.

[0063] The cyclone seat 21 of the left air curtain assembly is defined as a left cyclone seat, and the cyclone seat 21 of the right air curtain assembly is defined as a right cyclone seat. It can be understood that the structure of the left air curtain support is completely same as the structure of the right air curtain support, and the structure of the left cyclone seat is also completely same as the structure of the right cyclone seat.

[0064] When installing the left air curtain support, any air curtain support 112 can be selected as the left air curtain support installed at the left air curtain air outlet 111, as long as the clamping plate 1123 is close to the left end of the left air curtain support.

[0065] When installing the right air curtain support, any air curtain support 112 can be selected as the right air curtain support installed at the right air curtain air outlet 111, as long as the clamping plate 1123 is close to the right end of the right air curtain support.

[0066] That is to say, when the same air curtain support 112 is installed on different air curtain air outlets 111, only the clamping plate 1123 close to the left end or the right end needs to be simply distinguished.

[0067] When the left cyclone seat is installed, any cyclone seat 21 can be selected as the left cyclone seat, and since the bottom of the cyclone seat 21 is mirror-imaged with two groups of first buckles 212 at the left and right ends, no matter which end of the cyclone seat 21 faces left or right, the first buckle 212 on one end can be clamped with the clamping plate 1123 on the left air curtain support.

[0068] When the right cyclone seat is installed, any cyclone seat 21 can be selected as the right cyclone seat, and since the bottom of the cyclone seat 21 is mirror-imaged with two groups of first buckles 212 at the left and right ends, no matter which end of the cyclone seat 21 faces left or right, the first buckle 212 on one end can be clamped with the clamping plate 1123 on the right air curtain support.

[0069] Therefore, when the left air curtain assembly and the right air curtain assembly are installed, the same air curtain support 112 and cyclone seat 21 are used, and the difference is that the left and right ends of the left air curtain support are reversed relative to the left and right ends of the right air curtain support. By setting the air curtain support 112 and the cyclone seat 21 as universal parts, the operator does not need to distinguish the parts when installing the left and right air curtain assemblies 2, and only needs to simply distinguish the left and right ends of the air curtain support 112 when installing the air curtain support 112, thereby simplifying the installation process of the air curtain assembly 2 and improving the installation convenience.

[0070] The smoke machine of the utility model, such as Figure 12 and Figure 13 The right end of the left air curtain support 112 is provided with a supporting part 1124, the left end of the right air curtain support 112 is provided with a supporting part 1124, and the two ends of the cyclone seat 21 are provided with connecting parts 213, and the connecting part 213 on one side is connected with the supporting part 1124 on the corresponding side.

[0071] The supporting part 1124 is arched upward and avoids the raised part, and since the two ends of the cyclone seat 21 are provided with the connecting parts 213, no matter which end of the cyclone seat 21 faces left or right, the connecting part 213 on one end can be connected with the supporting part 1124 of the air curtain support 112.

[0072] Specifically, when the left cyclone seat is installed on the left air curtain support, the connecting part 213 at the right end is connected with the supporting part 1124 of the left air curtain support, and when the right cyclone seat is installed on the right air curtain support, the connecting part 213 at the left end is connected with the supporting part 1124 of the right air curtain support.
