The layout of the infrared module needs to be carefully considered during installation to ensure accurate measurement of the range hood's operating temperature. Currently, most side-draft range hoods require the flip panel to be opened for temperature measurement, making it inconvenient to use the infrared module at any time. Utility Model Content

[0003] The purpose of this utility model is to provide a range hood that has the advantages of easy access to the detection components and effective guarantee of the detection range of the detection components.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a range hood, including a smoke collection hood, a decorative strip, and a detection component. The smoke collection hood has an air inlet, and the detection component is installed on the smoke collection hood and located at the edge of the air inlet. The decorative strip is connected to the outer surface of the smoke collection hood and has a first light-transmitting hole opposite to the detection component. The detection component detects the cooking environment through the first light-transmitting hole.

[0006] Furthermore, the range hood also includes a flap, which rotates in conjunction with the smoke collection hood to open and close the air inlet. When the flap closes the air inlet, the outer surface of the flap is coplanar with the outer surface of the decorative strip.

[0007] Furthermore, the smoke hood includes an air inlet plate that is inclined relative to the vertical direction. The air inlet plate has the air inlet and an oil guide portion that extends into the inner cavity of the smoke hood.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0034] This embodiment provides a range hood, such as... Figures 1 to 5 As shown, the device includes a smoke hood 1, a decorative strip 2, and a detection component 3. The smoke hood 1 has an air inlet 111. The detection component 3 is installed on the smoke hood 1 and located at the edge of the air inlet 111. The decorative strip 2 is connected to the outer surface of the smoke hood 1 and has a first light-transmitting hole 21 that is opposite to the detection component 3. The detection component 3 detects the cooking environment through the first light-transmitting hole 21.

[0035] In the range hood provided in this embodiment, such as Figure 2 and Figure 3 As shown, it includes a decorative strip 2, which has a first light-transmitting hole 21, such as... Figure 4 and Figure 5 As shown, the detection component 3 is installed on the smoke hood 1 and located at the edge of the air inlet 111. When in operation, the detection component 3 can detect the cooking environment through the first light-transmitting hole 21 without being affected by the opening and closing of the air inlet 111. At the same time, since the detection component 3 is located at the edge of the air inlet 111 and is far away from the oil cup 5 of the range hood, it has a better detection field of view and can effectively ensure the detection range.

[0036] In alternative implementations, such as Figure 2 and Figure 3 As shown, the range hood also includes a flap 4, which rotates with the smoke collection hood 1 to open and close the air inlet 111. When the flap 4 closes the air inlet 111, the outer surface of the flap 4 is coplanar with the outer surface of the decorative strip 2.

[0037] In existing range hoods, a lower wall panel 12 is provided below the air inlet 111, and a whole glass flap is provided above the lower wall panel 12. The glass flap opens and closes the air inlet 111 by its own opening and closing. Since the detection component 3 mainly detects the stove below, the detection path needs a certain tilt angle. Therefore, the detection component 3 is preferably installed on the sloping surface of the air inlet 111. Because the air inlet 111 of the traditional range hood is blocked by the whole glass flap, the detection component 3 can only perform detection work after the whole glass flap is opened. This is not convenient for the detection component 3 to be used at any time. For example, when it is closed, it cannot detect the cooking environment and cannot control the opening and closing of the range hood according to the cooking environment detected by the detection component 3. In the above embodiment, the entire glass flap is designed in segments, with the upper segment being the flap 4 and the lower segment being the decorative strip 2. The detection component 3 can detect the cooking environment through the first light-transmitting hole 21 on the decorative strip 2, so that the detection process of the detection component 3 is not affected by the opening and closing of the flap 4. This allows the detection head of the detection component 3 to directly detect the temperature on the outer surface of the range hood, making it convenient for the detection component 3 to be used at any time. For example, it can simultaneously realize the opening and closing of the range hood, as well as the detection and change of the gear during use.

[0038] In addition, the above-described implementation makes the decorative strip 2 and the flap 4 appear as one piece when the flap 4 is closed, resulting in a more aesthetically pleasing appearance.

[0039] In an optional embodiment, the top of the flap 4 is hinged to the top of the smoke hood 1, and a push rod motor is provided between the flap 4 and the smoke hood 1. The opening and closing of the flap 4 can be controlled by the push rod motor.

[0040] The structure of the smoke hood 1 is described in detail below:

[0041] In alternative implementations, such as Figure 4 and Figure 5 As shown, the smoke hood 1 includes an air inlet plate 11 that is inclined relative to the vertical direction. The air inlet plate 11 has an air inlet 111 and an oil guide portion 112 that extends into the inner cavity of the smoke hood 1. The oil guide portion 112 has a second light-transmitting hole 1121 that is disposed opposite to the first light-transmitting hole 21. The detection component 3 is installed at the second light-transmitting hole 1121.

[0042] In the above embodiment, the air inlet plate 11 is inclined relative to the vertical direction, which can effectively absorb the gradually rising oil fumes. During use, the oil stains on the inner wall of the fume hood 1 will drip onto the air inlet plate 11. Since the air inlet plate 11 is inclined and the oil guide part 112 on the air inlet plate 11 extends into the inner cavity of the fume hood 1, the oil stains will drip down along the oil guide part 112 to the bottom of the inner cavity of the fume hood 1. The detection component 3 can detect the cooking environment through the second light-transmitting hole 1121 and the first light-transmitting hole 21 in sequence.

[0043] Specifically, the air inlet plate 11 gradually tilts towards the mounting surface of the range hood from top to bottom, and the oil guiding part 112 on the air inlet plate 11 also extends tilted in the same direction, so that the bottom end of the oil guiding part 112 is at the lowest position of the air inlet plate 11, which makes it easier for the oil guiding part 112 to guide the oil on the air inlet plate 11 to the inner cavity of the smoke collection hood 1.

[0044] In addition, the first light-transmitting hole 21 and the second light-transmitting hole 1121 can take various shapes, such as circular, elliptical, waist-shaped, rectangular, etc., without being specifically limited here.

[0045] Preferably, the shape of the second light-transmitting hole 1121 can be adapted to the shape of the detection head of the detection component 3, for example, the shape of the second light-transmitting hole 1121 is circular.

[0046] In alternative implementations, such as Figure 6 and Figure 7 As shown, the edge of the second light-transmitting hole 1121 is provided with a flange 1122 protruding towards the inner cavity of the smoke collection hood 1.

[0047] The aforementioned flange 1122 can prevent oil stains on the inner surface of the smoke hood 1 from flowing out through the second light-transmitting hole 1121, which helps to ensure the cleanliness of the outer surface of the range hood and reduces the difficulty for users to clean the range hood.

[0048] In alternative implementations, such as Figure 8 and Figure 9 As shown, the oil guide part 112 is recessed with a mounting groove 1123, and the mounting groove 1123 has a second light-transmitting hole 1121. The detection component 3 is installed in the mounting groove 1123.

[0049] The oil guide portion 112 has a recessed mounting groove 1123, and the detection component 3 can be partially embedded in the mounting groove 1123, which makes the installation of the detection component 3 more stable.

[0050] Specifically, the mounting groove 1123 can extend to the bottom of the oil guide section 112, so that after the oil stains on the inner wall of the smoke hood 1 drip onto the air inlet plate 11, some of the oil stains on the air inlet plate 11 can flow into the mounting groove 1123 and drip down to the bottom of the inner cavity of the smoke hood 1 through the mounting groove 1123.

[0051] Based on the above embodiments, the air inlet 111 can be provided with one air inlet or multiple air inlets. For example... Figure 8 and Figure 9 As shown, the air inlet 111 includes a first air inlet 1111 and a second air inlet 1112 arranged on the left and right sides. The first air inlet 1111 and the second air inlet 1112 together form a double air inlet cavity structure with the smoke hood 1. The oil guide 112 extends downward at an incline from the bottom end of the first air inlet 1111 and the second air inlet 1112 into the inner cavity of the smoke hood 1. The oil guide 112 is recessed at the gap between the first air inlet 1111 and the second air inlet 1112, with an installation groove 1123.

[0052] In use, the gap between the first air inlet 1111 and the second air inlet 1112 can catch the oil droplets dripping from the inner wall of the smoke hood 1, and guide the oil droplets into the inner cavity of the smoke hood 1 through the mounting groove 1123, so that the oil droplets fall to the bottom of the inner cavity of the smoke hood 1.

[0053] The structure of detection component 3 is described in detail below:

[0054] In alternative implementations, such as Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, the detection assembly 3 includes a connecting plate 31 and a detector 32. The detector 32 is connected to the oil guide part 112 through the connecting plate 31. The detector 32 has a detection head that is positioned directly opposite the second light-transmitting hole 1121.

[0055] The aforementioned detection component 3 includes a connecting plate 31, allowing the detector 32 to connect to the oil guide 112 via the connecting plate 31, thus facilitating the connection between the detector 32 and the oil guide 112. Figure 9 As shown, the connecting plate 31 can be bent and extends into the mounting groove 1123 and fits against the inner wall of the mounting groove 1123. The connecting plate 31 has a first connecting hole, and the oil guide part 112 has a second connecting hole. Screws and other connecting parts can pass through the first connecting hole and the second connecting hole to connect the connecting plate 31 and the oil guide part 112.

[0056] The connecting plate 31 also includes a wing plate, which extends out of the mounting groove 1123 and is parallel to and spaced apart from the oil guide part 112. A third connecting hole is provided on the wing plate, and a fourth connecting hole is provided on the detector 32. Screws and other connecting parts can pass through the fourth connecting hole and the third connecting hole to connect the connecting plate 31 and the detector 32.

[0057] If the detector 32 is directly exposed inside the smoke hood 1, the oil stains on the inner wall of the smoke hood 1 will drip onto the detector 32. Therefore, in an optional embodiment, the detection assembly 3 also includes an oil-proof cover 33 connected to the connecting plate 31, and the oil-proof cover 33 is placed on the outside of the detector 32.

[0058] The oil-proof cover 33 can prevent oil from flowing into the detector 32, which helps to ensure the normal operation of the detector 32.

[0059] Specifically, the oil-proof cover 33 is provided with a fifth connecting hole, through which screws and other connecting parts can pass to connect the oil-proof cover 33, the detector 32 and the connecting plate 31.

[0060] In an optional embodiment, the oil-proof cover 33 has a semi-enclosed structure and is directly snapped onto the outside of the detector 32, which makes it easier to install the oil-proof cover 33.

[0061] In alternative implementations, such as Figure 5 As shown, the oil-proof cover 33 includes a first cover 331 and a second cover 332. The first cover 331 is connected to the connecting plate 31 and covers the outside of the detector 32. The first cover 331 includes a vertically arranged first oil guide plate 3311. The second cover 332 includes a second oil guide plate 3321 connected to the first oil guide plate 3311 at an obtuse angle. The end of the second oil guide plate 3321 away from the first oil guide plate 3311 extends to the bottom end of the oil guide portion 112.

[0062] When in use, the oil stains on the inner wall of the smoke hood 1 will drip onto the first cover 331, and can flow along the first oil guide plate 3311 to the second oil guide plate 3321, and finally drip from the second oil guide plate 3321 to the bottom of the inner cavity of the smoke hood 1.

[0063] In the above embodiments, the oil on the oil cover 33 can drip directly from the second oil guide plate 3321 to the bottom of the inner cavity of the smoke collection hood 1, reducing or even preventing the oil on its outer surface from seeping into the detector 32, thus ensuring the service life of the detector 32.

[0064] The first oil guide plate 3311 and the second oil guide plate 3321 can form an obtuse angle of 100°, 110°, 120°, or 130°.

[0065] In an optional embodiment, the second oil guide plate 3321 is arranged parallel to the oil guide portion 112, and the size of the angle can be related to the tilt angle of the oil guide portion 112.

[0066] Specifically, to facilitate the processing of the oil-proof cover 33, the oil-proof cover 33 can be made from a cuboid box cover. Specifically, the cuboid box cover is reduced in size and bent to form an obtuse-angled folded cover slope, so that oil can drip down the folded cover to the bottom of the smoke collection hood 1.

[0067] It is understood that the aforementioned folding cover slope includes the outer surfaces of the first oil guide plate 3311 and the second oil guide plate 3321.

[0068] The structure of decorative strip 2 is described in detail below:

[0069] In an optional embodiment, the decorative strip 2 can be fixed to the outer surface of the edge of the air inlet 111 in the air inlet plate 11 by several screws. The oil stains on the upper part of the inner wall of the air inlet plate 11 can flow to the decorative strip 2, flow through the decorative strip 2 to the oil guide part 112, and finally drip to the bottom of the smoke hood 1.

[0070] In an optional embodiment, the detector 32 is located at the center of the decorative strip 2. The center of the decorative strip is designed with a hollowed-out chamfer to form a first light-transmitting hole 21. The first light-transmitting hole 21 is coaxial with the temperature sensing center of the detection head on the detector 32, which facilitates the detection head to realize temperature detection.

[0071] In alternative implementations, such as Figure 10 As shown, the fume hood 1 also includes a lower wall panel 12 extending vertically. The lower wall panel 12 is located below the decorative strip 2, and an oil cup 5 can be installed at the bottom of the lower wall panel 12. Since the position of the lower wall panel 12 is relatively low compared to the position of the air inlet 111, if the detection component 3 is installed on the lower wall panel 12, on the one hand, the detection component 3 will be limited by the installation height, resulting in its radiation range not being able to fully cover the stove; on the other hand, since the detection component 3 mainly detects the stove below, the detection path needs a certain tilt angle, and since the lower wall panel 12 extends vertically, installing the detection component 3 on the lower wall panel 12 does not facilitate the radiation of the detection path of the detection component 3 to the stove, which is not conducive to the installation of the detection component 3.

[0072] In alternative implementations, such as Figure 10 and Figure 11 As shown, the decorative strip 2 has a notch 23 recessed at one end near the lower wall panel 12, extending toward the inner cavity of the smoke hood 1, and a guide channel is formed between the notch 23 and the lower wall panel 12.

[0073] When in use, the guide channel can guide the oil stains on the surface of the decorative strip 2 into the inner surface of the lower wall panel 12, so that they flow into the fume hood 1 and finally into the oil cup 5 through the internal oil passage, effectively preventing the oil stains on the surface of the decorative strip 2 from flowing directly into the outer surface of the lower wall panel 12.

[0074] In alternative implementations, such as Figure 11 As shown, the decorative strip 2 has a groove 22 recessed on the inner surface of the smoke hood 1 facing the inner cavity.

[0075] The groove 22 mentioned above can increase the contact surface area between the decorative strip 2 and the high-temperature oil fume condensation, accelerate the condensation of oil fumes, and at the same time save the material used in the decorative strip 2.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
