[0050] As shown in Figure 3 As shown in

[0051] The oil guide strip is arranged obliquely above the temperature sensing installation structure, so as to guide the oil flowing downward from top to left and right sides of the temperature sensing installation structure, reduce the influence of the oil flowing downward from top on the temperature sensing module 100, reduce the oil around the temperature sensing module 100, and improve the service life thereof.

[0052] As shown in Figure 3 , the oil guide strip located at one side of the temperature sensing installation structure at least includes a first strip body 210 and a second strip body 220 arranged discontinuously along the vertical direction, and the first strip body 210 and the second strip body 220 are both higher at the end close to the temperature sensing installation structure than at the end away from the temperature sensing installation structure, that is, the first strip body 210 and the second strip body 220 have the same oblique direction, and the first strip body 210 and the second strip body 220 can be arranged in parallel or can not be arranged in parallel.

[0053] The downward projection of the end of the first strip body 210 away from the temperature sensing installation structure falls on the second strip body 220, so that the oil drops flowing downward from the end of the first strip body 210 away from the temperature sensing installation structure can fall on the second strip body 220, and the first strip body 210 and the second strip body 220 are arranged in staggered positions to increase the oil receiving area, a part of the oil flowing downward from top to bottom falls on the first strip body 210, and a part of the oil falls on the second strip body 220, and the oil falling on the first strip body 210 will fall on the second strip body 220 under the guidance of the inclined first strip body 210, and finally is discharged from the left and right sides and falls into the oil cup.

[0054] As shown in Figure 3 , Figure 7 , Figure 9 , in the embodiment, the oil guide structure includes a bellows 2 and a fume hood 1, the bellows 2 is connected to the top of the fume hood 1, and a wind channel system is installed in the bellows 2. The first strip body 210 is arranged on the bellows 2, and the second strip body 220 and the temperature sensing installation structure are arranged on the back of the front plate of the fume hood 1. The oil flowing downward on the inner wall of the bellows 2 first falls on the first strip body 210, and then drips downward on the second strip body 220 of the fume hood 1. From the bellows 2, the oil path is regulated, so as to guide the oil to travel in the preset direction, avoid the oil directly dripping on the temperature sensing module 100, and comprehensively cover the inner wall of the bellows 2 and the fume hood 1 by the separately arranged oil guide strips, thereby reducing the dead angle.

[0055] Specifically, as shown in Figure 7 and Figure 9 , the top of the fume hood 1 is arranged in the horizontal direction, and the top is provided with an assembly opening. The bottom of the bellows 2 is provided with a skirt 310 connected with the assembly opening. The front of the bellows 2 has an upper plate 21 and a lower plate 22 arranged in the up-down direction, and the two can be integrally formed. Among them, the upper plate 21 is arranged vertically, and the lower plate 22 is arranged obliquely. From top to bottom, the lower plate 22 is inclined to the rear side. The skirt 310 is located between the lower plate 22 and the inner wall of the assembly opening, and the three are connected by screws. Figure 9The lower side of the front side edge of the skirt 310 is provided with a downwardly extending flange 320, which is inclined downwardly from top to bottom, thereby guiding the oil stains to flow to the rear side. Meanwhile, the lower edge of the flange 320 is designed to be inclined, that is, the lower edge is higher at the end close to the temperature sensing mounting structure than at the end away from the temperature sensing mounting structure, so that the lower edge of the flange 320 forms the first strip 210. The oil stains on the upper plate 21 fall onto the second strip 220 in sequence through the lower plate 22 and the flange 320.

[0056] As shown in Figure 3 , the second strip 220 is formed by a strip-shaped protruding rib protruding inwardly from the inner wall of the front plate of the fume hood 1. The protruding rib is integrally formed with the inner wall of the front plate of the fume hood 1, and of course, a split design can also be adopted, that is, the second strip 220 is an independent component relative to the fume hood 1 and is connected to the fume hood 1 by means of gluing or the like. The front plate of the fume hood 1 is arranged to be inclined relative to the horizontal plane, and is inclined downwardly from front to back. The fume hood 1 is further connected with a lower cover body 600 below, and the front plate of the lower cover body 600 extends vertically and is connected with the front plate of the fume hood 1 in an up-down manner.

The outer wall of the front plate of the fume hood 1 has an inwardly recessed sunken table 12, and the bottom surface of the sunken table 12 is provided with the smoke inlets. The edge of the oil screen 3 abuts on the bottom surface of the sunken table 12 and covers the smoke inlets.

[0058] As shown in Figure 4 , the edge of the smoke inlet is provided with a first flange 410 inwardly folded, and the first flange 410 can be perpendicular to the front plate of the fume hood 1. The smoke inlet is substantially rectangular, and the upper edge of the first flange 410 is located below the end of the oil guiding strip away from the temperature sensing mounting structure, so as to receive the oil stains flowing down from the oil guiding strip. That is, the oil stains flowing down from the oil guiding strip will first fall on the upper edge of the first flange 410, and then flow outwardly and fall into the oil cup.

[0059] In order to avoid the oil stains on the upper edge of the first flange 410 flowing towards the side of the temperature sensing module 100, the upper edge of the first flange 410 is provided with a first protrusion 411 protruding upwardly. In the left-right direction, the first protrusion 411 is located at a position between the end of the corresponding oil guiding strip away from the temperature sensing mounting structure and the temperature sensing mounting structure, thereby achieving the purpose of blocking oil.

[0060] In order to further prevent the oil stains on the upper edge of the first flange 410 from flowing into the position where the temperature sensing module 100 is located, the upper edge of the first flange 410 is also provided with a notch 412, which is located at a position between the first protrusion 411 and the temperature sensing mounting structure in the left-right direction. Even if a small part of the oil stains passes over the first protrusion 411, it will also fall from the notch 412 onto the oil screen 3, and the oil stains on the oil screen 3 will eventually flow into the oil cup. The notch 412 is provided with a guide groove 413, the upper end of which is in communication with the notch 412, and the lower end is located at the rear side of the oil screen 3.

[0061] The guide groove 413 can also be provided with a through hole for connecting with the oil screen 3, so that the oil screen 3 is connected with the guide groove 413 by screws.

[0062] The other side of the guide groove 413 relative to the first protrusion 411 can be provided with a symmetrical second protrusion 414. When the guide groove 413 is blocked, the second protrusion 414 can play a role in raising the oil overflow level of the guide groove 413, slowing down the flow of oil stains over the guide groove 413 to the side of the temperature sensing module 100.

[0063] As shown in Figure 5 , Figure 10 and Figure 11 , the temperature sensing mounting structure includes a mounting hole, the edge of which is provided with a second flange 510 that is folded inwardly to the inside of the fume hood 1, and the height of the second flange 510 is H1. The temperature sensing mounting structure includes a temperature sensing module 100 bracket 540, which is fastened with the fume hood 1. The temperature sensing module 100 itself is designed to be sealed, waterproof and oil-proof, and has a front window 530 of the temperature sensing detection module, which is designed to have a certain step height H2 and is circular in shape, so as to ensure that the window 530 of the temperature sensing detection module is embedded in the second flange 510. The outside of the mounting hole is provided with an outer opening for mounting a temperature sensing silicon wafer and is designed to be sealed, which is used for the transmission of detection signals. The temperature sensing mounting structure also includes a rear cover 520, which is fixed to the back of the temperature sensing module 100, and can cover the entire temperature sensing module 100, as shown in Figure 6 .

[0064] As shown in Figure 1 , the front wall of the front panel of the fume hood 1 is provided with a decorative strip 4, the back of which is fastened with the fume hood 1 by screws, and the middle of the decorative strip 4 is designed to be hollow for the signal of the temperature sensing detection module to pass through.

[0065] As shown in Figure 8 , the front panel of the fume hood 1 is provided with an inclined surface located upwardly to the sink 12, and the angle A5° between the inclined surface and the horizontal plane is between 7° and 15°, which is beneficial for the flow of oil droplets. The second strip 220 is arranged on the inclined surface, and the inclined surface is located directly below the folded edge 320.

[0066] The mounting groove 550 is outwardly convex between the two smoke inlets, and after the temperature sensing module 100 is connected with the temperature sensing mounting structure, the temperature sensing module 100 as a whole or a part is located inside the mounting groove 550.

[0067] In the embodiment, a part of the support 540 can be located inside the mounting groove 550, the mounting hole is also located inside the mounting groove 550, a part of the temperature sensing module 100 is mounted into the mounting groove 550, and the window 530 thereof is butted with the mounting hole, so that less part of the temperature sensing module 100 protrudes outside the mounting groove 550, the back of the front panel of the smoke collecting cover 1 is more streamlined, and the temperature sensing module 100 can reduce the hindrance to the airflow inside the range hood.

[0068] The range hood provided by the utility model comprises the oil guiding structure, and the range hood provided by the utility model has the advantages of the oil guiding structure.
