[0001] The invention relates to the field of kitchen appliances, and in particular to a range hood. Background Art

[0002] A range hood is a kitchen appliance used to purify the kitchen environment. It can quickly extract the fumes generated by the stove under the range hood during cooking and discharge them outdoors to purify the kitchen environment. The oil stains filtered by the range hood are collected in an oil cup.

[0003] Due to the top-down nature of the range hood oil path, an oil cup is usually hung on the bottom of the range hood body to facilitate the collection of oil stains. However, as a directly visible component, the oil cup is exposed under the range hood body, which will affect the overall appearance of the range hood.

[0004] In the related art, the oil cup is arranged inside the smoke hood to solve the above-mentioned problem of affecting the aesthetics. However, the oil cup is arranged inside the smoke hood, which makes it inconvenient to disassemble and assemble the oil cup, thereby affecting the user experience. Summary of the invention

[0054] A range hood is a kitchen appliance used to purify the kitchen environment. It can quickly extract the fumes generated by the stove under the range hood during cooking and discharge them outdoors to purify the kitchen environment. The oil stains filtered by the range hood are collected in an oil cup.

[0055] Due to the top-down nature of the range hood oil path, an oil cup is usually hung on the bottom of the range hood body to facilitate the collection of oil stains. However, as a directly visible component, the oil cup is exposed under the range hood body, which will affect the overall appearance of the range hood.

[0056] In the related art, the oil cup is arranged inside the smoke hood to solve the above-mentioned problem of affecting the aesthetics. However, the oil cup is arranged inside the smoke hood, which makes it inconvenient to disassemble and assemble the oil cup, thereby affecting the user experience.

[0057] refer to Figure 1 and Figure 2The embodiment of the present application provides a range hood 1, which can be a side suction range hood, a top suction range hood, etc. The range hood 1 includes a housing 10, a decorative cover 12, and a fume collecting cover 20. The decorative cover 12 is located outside the housing 10, and the outside refers to the side away from the inside of the housing 10. The decorative cover 12 is used to decorate and protect the range hood 1, and the decorative cover 12 is connected to the housing 10.

[0058] Exemplarily, the decorative cover 12 may be connected to the housing 10 by means of threaded connection, snap connection, magnetic connection, or the like.

[0059] refer to Figure 3 , and combined with Figure 1 The fume hood 20 is located below the housing 10 and connected to the housing 10. The housing 10 is formed with a mounting cavity 100. The mounting cavity 100 is provided with an oil leakage hole 601. The fume hood 20 is provided with a smoke inlet 200 for allowing oil smoke to enter the mounting cavity 100. The range hood 1 further includes a fan 60, which is mounted in the mounting cavity 100. The oil leakage hole 601 is provided at the bottom of the fan 60. After the oil smoke entering the mounting cavity 100 is separated by the fan 60, part of the oil stain flows out through the oil leakage hole 601, and the other part is thrown onto the inner wall of the housing 10 and flows downward along the inner wall of the housing 10. Figure 3 The arrow in the middle points to the direction of oil flow.

[0060] For example, the housing 10 may be connected to the smoke hood 20 by means of threaded connection, snap connection, or the like.

[0061] refer to Figure 4 and Figure 5 , and combined with Figure 3 The range hood 1 further comprises an oil collecting component 30, an oil guiding component 50 and an oil cup 40. The oil collecting component 30 is arranged at the smoke inlet 200 and connected to the smoke collecting hood 20. The oil collecting component 30 comprises an oil collecting chamber 300, and the opening of the oil collecting chamber 300 is located below the oil leakage hole 601 and the inner wall of the housing 10.

[0062] In this way, part of the oil in the installation cavity 100 can flow to the oil collecting cavity 300 through the oil leakage hole 601, and the other part of the oil thrown onto the inner wall of the shell 10 can flow along the inner wall to the bottom end of the inner wall and then flow to the oil collecting cavity 300, so that all the oil inside the shell 10 can be collected in the oil collecting cavity 300.

[0063] refer to Figure 6 , and combined with Figure 2 and Figure 4The oil cup 40 is arranged inside the fume hood 20. The oil cup 40 includes an oil containing cavity 400. The fume hood 20 is provided with an installation opening 201. The oil cup 40 is detachably installed at the installation opening 201. In this way, the oil cup 40 is arranged inside the fume hood 20, that is, the oil cup 40 is hidden inside the fume hood 20. The oil cup 40 cannot be seen when the range hood 1 is viewed from the front or from the side, which greatly improves the overall aesthetics of the range hood 1. At the same time, the opening of the oil cup 40 is located inside the fume hood 20, thereby preventing the oil stains in the oil cup 40 from contacting the air outside the range hood 1, and reducing the spread of bacteria.

[0064] In addition, the range hood 1 provided in the present application can take out and put in the oil cup 40 through the installation opening 201 , which is more convenient, faster, and more labor-saving than plugging the oil cup 40 into the shell 10 , and can improve the user's use effect.

[0065] refer to Figure 7 , and combined with Figure 4 The oil guide component 50 is disposed inside the fume hood 20 and connected to at least one of the fume hood 20 and the oil collecting component 30. That is, the oil guide component 50 is connected to the fume hood 20, or the oil guide component 50 is connected to the oil collecting component 30, or the oil guide component 50 is connected to both the fume hood 20 and the oil collecting component 30. The oil guide component 50 includes an oil guide channel 500, and the oil inside the housing 10 can flow to the oil containing chamber 400 through the oil collecting chamber 300 and the oil guide channel 500 in sequence.

[0066] In this way, the oil flowing into the oil collecting chamber 300 can eventually flow into the oil containing chamber 400 of the oil cup 40 along the oil guide channel 500, so that all the oil inside the shell 10 is collected in the oil cup 40, ensuring the cleanliness of the interior of the range hood 1.

[0067] Therefore, the range hood 1 provided in the embodiment of the present application can solve the problem of poor appearance of the range hood 1 and the problem of affecting the health of users. At the same time, the oil circuit system designed in the embodiment of the present application can collect all the oil stains inside the shell 10, thereby improving the oil removal performance of the range hood 1 and enhancing the user experience.

[0068] Generally, the gap between the smoke hood 20 and the wall is small. By setting the oil guide component 50, no matter where the oil cup 40 is set in the smoke hood 20, it can be ensured that the oil inside the shell 10 flows from the oil collecting chamber 300 to the oil cup 40, so that the oil cup 40 can be set, for example, at a position away from the wall for easy disassembly and assembly.

[0069] Therefore, the range hood 1 provided in the embodiment of the present application can solve the problem of inconvenient assembly and disassembly of the oil cup.

[0070] Exemplarily, the oil guide component 50 may be connected to the fume hood 20 by means of threaded connection, snap-fitting, etc.; the oil guide component 50 may also be connected to the oil collecting component 30 by means of threaded connection, snap-fitting, etc.

[0071] refer to Figure 8 , and combined with Figure 3 The range hood 1 further includes an oil guide plate 11, which is located inside the smoke hood 20. The housing 10 extends into the smoke hood 20 and is connected to the smoke hood 20. One end of the oil guide plate 11 is connected to the inner wall of the housing 10, and the other end is located above the oil collecting chamber 300. The oil guide plate 11 includes an oil guide surface 110, which is inclined downward from one end of the oil guide surface 110 to the other end. In this way, one end of the oil guide surface 110 can receive the oil flowing down from the inner wall of the housing 10, and then flow along the oil guide surface 110 to the other end of the oil guide surface 110. The other end of the oil guide surface 110 is located above the opening of the oil collecting chamber 300, so that the oil flowing to the other end of the oil guide surface 110 can be collected in the oil collecting chamber 300.

[0072] An oil receiving portion 61 is provided below the fan 60, and the oil receiving portion 61 includes an oil receiving chamber (not shown in the figure), the oil receiving chamber is located below the oil leakage hole 601, and the end of the oil receiving chamber is located above the oil guide surface 110. In this way, the oil flowing out through the oil leakage hole 601 can flow to the oil guide surface 110 through the oil receiving chamber.

[0073] In this way, a part of the oil in the installation cavity 100 can flow to the oil collecting cavity 300 through the oil leakage hole 601, the oil receiving cavity, and the oil guiding surface 110 in sequence, and another part of the oil thrown onto the inner wall of the shell 10 can flow along the inner wall to the bottom end of the inner wall and then flow to the oil collecting cavity 300, or flow along the inner wall to the bottom end of the inner wall and then flow to the oil collecting cavity 300 through the oil guiding surface 110, so that all the oil inside the shell 10 can be collected in the oil collecting cavity 300.

[0074] In some embodiments, there is a height difference between the position of the oil guide component 50, the position of the oil cup 40 and the position of the oil collecting component 30, that is, the oil guide channel 500, the oil containing chamber 400 and the oil collecting chamber 300 are not directly connected, and the head end of the oil guide channel 500 is located below the oil outlet of the oil collecting chamber 300, and the end of the oil guide channel 500 is located above the opening of the oil containing chamber 400, so that the oil in the oil collecting chamber 300 can flow into the oil containing chamber 400 through the oil outlet of the oil collecting chamber 300 and the oil guide channel 500 in sequence.

[0075] In some other embodiments, the oil guiding channel 500 directly connects the oil collecting chamber 300 and the oil containing chamber 400, that is, the oil outlet of the oil collecting chamber 300 is connected to the head end of the oil guiding channel 500, and the end of the oil guiding channel 500 is connected to the opening of the oil containing chamber 400, so that the oil inside the shell 10 flows to the oil containing chamber 400 through the oil collecting chamber 300 and the oil guiding channel 500 in sequence.

[0076] Exemplarily, the oil guide component 50 is a groove-shaped structure, which includes a bottom wall and two opposite side walls. The two side walls and the bottom wall form an oil guide channel 500. One opening of the groove-shaped structure faces upward and is connected to the oil collecting chamber 300. The other opening is the opening at the end of the oil guide channel 500 and is connected to the oil containing chamber 400.

[0077] refer to Fig. 9 , and combined with Figure 7 In some possible embodiments, the oil guide component 50 is composed of two groove-shaped structures. The parts where the two groove-shaped structures are connected can be connected by snapping, threading, gluing, etc. At the same time, attention should be paid to the sealing of the connection between the two groove-shaped structures. The gap at the connection can be filled with sealant or sealing sponge, sealing rubber, etc. to seal it, so that the oil stains in the oil guide channel 500 will not flow out from the gap at the connection to the interior of the smoke hood 20, thereby ensuring the cleanliness of the interior of the smoke hood 20, and then ensuring the working reliability of the range hood 1.

[0078] In some possible embodiments, the oil guide component 50 gradually slopes downward from the head end to the tail end, so that the oil in the oil guide channel 500 can be ensured to flow smoothly into the oil containing cavity 400 .

[0079] Continue to refer Figure 5 and Figure 7 In some embodiments, at least one first oil guide hole 301 is provided on the oil collecting component 30, and the first oil guide hole 301 is connected to the oil collecting chamber 300. At least one second oil guide hole 501 is provided on the oil guiding component 50, and the second oil guide hole 501 is connected to the oil guiding channel 500. The first oil guide hole 301 and the second oil guide hole 501 correspond to each other.

[0080] The oil collecting component 30 is also provided with an oil guiding connection part 31 corresponding to the first oil guiding hole 301 , and the oil guiding connection part 31 includes an oil guiding connection channel 310 , and the oil guiding connection part 31 passes through the first oil guiding hole 301 and the second oil guiding hole 501 , so that the first oil guiding hole 301 is connected with the second oil guiding hole 501 through the oil guiding connection channel 310 .

[0081] In this way, the oil collecting chamber 300, the first oil guide hole 301, the oil guide connecting channel 310, the second oil guide hole 501, and the oil guide channel 500 are connected in sequence, so that the oil in the oil collecting chamber 300 can flow into the oil guide channel 500 through the first oil guide hole 301, the oil guide connecting channel 310, and the second oil guide hole 501 in sequence, and finally flow into the oil containing chamber 400 of the oil cup 40 through the oil guide channel 500, thereby completing the collection of oil inside the shell 10.

[0082] It can be understood that the first oil guide hole 301 is located at the bottom of the oil collecting component 30 or at a position close to the bottom of the side. In this way, it can ensure that as much as possible or all of the oil flowing into the oil collecting chamber 300 flows out through the first oil guide hole 301, thereby ensuring the cleanliness of the oil collecting chamber 300.

[0083] For example, the number of the first oil guide hole 301, the second oil guide hole 501 and the oil guide connection part 31 can be set as needed, and the shape and size of the first oil guide hole 301 and the second oil guide hole 501 can be set as needed, which is not specifically limited in this embodiment.

[0084] Continue to refer Figure 4 and Figure 5 In some possible embodiments, the oil guide connection portion 31 is formed by extending the portion of the oil collecting component 30 located at the first oil guide hole 301 outward, and the outer side refers to the side away from the oil collecting cavity 300, so as to ensure that the first oil guide hole 301 is connected to the oil guide connection channel 310. The oil guide connection portion 31 is integrally formed with the oil collecting component 30, and the structure is simple, which is conducive to improving the structural stability of the oil collecting component 30.

[0085] refer to Fig.10 , and combined with Figure 4 In some embodiments, the smoke collecting hood 20 includes a first flange 21, which is formed by extending the portion of the smoke collecting hood 20 located at the smoke inlet 200 toward the inside of the smoke collecting hood 20. Fig.10 The oil collecting component 30 is located on the side of the first flange 21 away from the inside of the smoke collecting hood 20, that is, the oil collecting component 30 is located on the inner side of the first flange 21, and the inner side refers to the side of the first flange 21 away from the inside of the smoke collecting hood 20 and connected to the first flange 21.

[0086] The oil guide component 50 is disposed on the side of the first flange 21 facing the inside of the fume hood 20, that is, the oil guide component 50 is located on the outside of the first flange 21, and the outside refers to the side of the first flange 21 close to the inside of the fume hood 20, and is connected to at least one of the first flange 21 and the oil collecting component 30. That is, the oil guide component 50 is connected to the first flange 21, or the oil guide component 50 is connected to the oil collecting component 30, or the oil guide component 50 is connected to both the first flange 21 and the oil collecting component 30.

[0087] Exemplarily, the oil guiding component 50 may be connected to the first flange 21 by means of threaded connection, snap-fitting, etc., and the oil guiding component 50 may also be connected to the oil collecting component 30 by means of threaded connection, snap-fitting, etc.

[0088] At least one third oil guide hole (not shown in the figure) is formed on the first flange 21, and the third oil guide hole corresponds to the first oil guide hole 301. The oil guide connecting portion 31 passes through the first oil guide hole 301, the third oil guide hole and the second oil guide hole 501, so that the first oil guide hole 301 is connected with the second oil guide hole 501 through the oil guide connecting channel 310.

[0089] In this way, the oil collecting chamber 300, the first oil guide hole 301, the oil guide connecting channel 310, the second oil guide hole 501, and the oil guide channel 500 are connected in sequence, so that the oil in the oil collecting chamber 300 can flow into the oil guide channel 500 through the first oil guide hole 301, the oil guide connecting channel 310, and the second oil guide hole 501 in sequence, and finally flow into the oil containing chamber 400 of the oil cup 40 through the oil guide channel 500, thereby completing the collection of oil inside the shell 10.

[0090] Exemplarily, the shape and size of the third oil guide hole can be set as required, and this embodiment does not specifically limit this, as long as it is ensured that the oil guide connection part 31 can pass through the third oil guide hole.

[0091] In some embodiments, the housing 10 includes a mounting portion, and the mounting portion is suitable for connecting to a wall to connect the range hood 1 to the wall.

[0092] Exemplarily, the mounting portion may be a foot, which is disposed on a side wall of the housing 10 that is opposite to and close to the wall. The foot may be connected to the wall by threaded connection, snap-on connection, etc. to hang the range hood 1 on the wall.

[0093] Continue to refer Figure 3 and Figure 8 The range hood 1 further comprises an oil net 70, which is arranged at the smoke inlet 200 and has a plurality of mesh holes for allowing the smoke to pass through and enter the housing 10. The oil net 70 is located above the oil collecting component 30 and is connected to the smoke collecting hood 20.

[0094] Exemplarily, the oil net 70 can be connected to the fume hood 20 by threaded connection, clamping, etc. The edge of the oil net 70 is also formed with a flange extending toward the inside of the fume hood 20, which can be connected to the first flange 21 by threaded connection to connect the oil net 70 to the fume hood 20.

[0095] refer to Fig.11 , and combined with Figure 3In some embodiments, one end of the oil net 70 away from the wall is higher than the other end of the oil net 70 close to the wall, at least one oil drain hole 700 is provided at the edge of the oil net 70, at least one oil drain hole 700 is provided at the end of the edge of the oil net 70 close to the wall, and at least one oil drain hole 700 is located below the inner wall and above the opening of the oil collecting chamber 300.

[0096] refer to Fig.12 and Fig.13 In this way, the oil stains flowing down the inner wall of the housing 10 away from the wall can first flow to the edge of the oil net 70, and together with the oil stains flowing down the inner wall of the housing 10 close to the wall, are collected at the edge of the oil net 70 close to one end of the wall, and then flow to the oil collecting chamber 300 below through at least one oil drain hole 700. The oil circuit system designed in this way can ensure that the oil stains inside the housing 10 are discharged smoothly, which is conducive to ensuring the cleanliness of the inside of the housing 10.

[0097] In some other embodiments, the end of the oil net 70 away from the wall is at the same height as the end of the oil net 70 close to the wall. In this case, a plurality of oil drain holes 700 are arranged at intervals around the edge of the oil net 70. The oil drain holes 700 are located below the inner wall and above the opening of the oil collecting chamber 300. In this way, the oil drain holes 700 are arranged on the corresponding edges of the oil net 70 below each inner wall of the housing 10.

[0098] In this way, it can be ensured that the oil stains on the inner walls of the shell 10 flow down to the edge of the oil net 70. Even if the oil net 70 is not set at an angle, the oil stains flowing to the bottom of each inner wall can also flow from the corresponding oil drain holes 700 on the edge of the oil net 70 to the oil collecting chamber 300 below the oil net 70.

[0099] Exemplarily, the shape and size of the oil drain hole 700 can be set as needed. For example, the shape of the oil drain hole 700 can be circular, elliptical, etc. The size design of the oil drain hole 700 should ensure that the oil will not cause blockage when passing through the oil drain hole 700, and ensure that the oil can pass smoothly. This embodiment does not impose any limitations on this.

[0100] Continue to refer Figure 5 In some embodiments, the oil collecting component 30 is an annular structure, which includes an inner peripheral wall, an outer peripheral wall and a bottom wall. The inner peripheral wall and the outer peripheral wall are opposite to each other, and the bottom wall is located between the inner peripheral wall and the outer peripheral wall. The inner peripheral wall, the outer peripheral wall and the bottom wall form an oil collecting chamber 300, and the outer peripheral wall is connected to the smoke hood 20.

[0101] Thus, even if the oil collecting member 30 is located below the oil net 70, the oil smoke will not be blocked from entering the housing 10 through the multiple meshes of the oil net 70. At the same time, the oil collecting member 30 is set as a ring structure, which can make full use of the structural characteristics, realize the collection of oil pollution, and has a simple structure.

[0102] Exemplarily, the outer peripheral wall of the annular structure is connected to the first flange 21 by means of threaded connection, clamping, etc., so as to connect the oil collecting component 30 to the smoke collecting hood 20.

[0103] In some embodiments, the end of the oil collecting component 30 away from the wall is higher than the end of the oil collecting component 30 close to the wall, and a first oil guide hole 301 is provided on the end of the oil collecting component 30 close to the wall. This facilitates all the oil in the oil collecting chamber 300 to flow smoothly through the first oil guide hole 301, the oil guide connecting channel 310 and the second oil guide hole 501 to the oil guide channel 500.

[0104] In some embodiments, a mounting opening 201 is provided on a portion of the smoke hood 20 extending toward one side of the housing 10, a first connecting portion is provided on the oil cup 40, and a second connecting portion is provided on the smoke hood 20. The first connecting portion and the second connecting portion include a connected state and a separated state. When the first connecting portion and the second connecting portion are in the connected state, the first connecting portion is connected to the second connecting portion, so that the oil cup 40 is installed inside the smoke hood 20; when the first connecting portion and the second connecting portion are in the separated state, the first connecting portion is disconnected from the second connecting portion, so that the oil cup 40 is detached from the smoke hood 20.

[0105] Exemplarily, the installation opening 201 can be located at any side of the smoke hood 20. When the thickness of the foot is large enough, the installation opening 201 can also be located on the side of the smoke hood 20 close to the wall, as long as the oil cup 40 can be smoothly loaded and unloaded.

[0106] refer to Fig.14 , and combined with Figure 6 The oil cup 40 includes an oil containing cavity 400 with an opening facing upward and a grabbing cavity 401 with an opening facing downward. The grabbing cavity 401 is convenient for the user to grab the oil cup 40 .

[0107] In some possible embodiments, the first connection portion is a recessed portion, and the second connection portion is a protruding portion, and the protruding portion can be inserted into the recessed portion to connect the first connection portion with the second connection portion, thereby installing the oil cup 40 on the smoke hood 20. Under the action of an external force, for example, the oil cup 40 is pulled out toward the outside of the smoke hood 20, and the protruding portion can be disengaged from the recessed portion, so that the first connection portion is disconnected from the second connection portion, thereby removing the oil cup 40.

[0108] In some possible embodiments, the first connecting part is a first magnetic part, and the second connecting part is a second magnetic part. The first magnetic part and the second magnetic part include a connected state and a separated state. When the first magnetic part and the second magnetic part are in the connected state, the first magnetic part and the second magnetic part are magnetically connected to connect the first connecting part to the second connecting part, thereby installing the oil cup 40 on the smoke hood 20.

[0109] When the first magnetic part and the second magnetic part are in a separated state, under the action of external force, for example, the oil cup 40 is pulled out toward the outside of the smoke hood 20. Even if there is still magnetic force between the first magnetic part and the second magnetic part, the first magnetic part and the second magnetic part can still be disconnected from the magnetic connection, so that the first connection part is disconnected from the second connection part, thereby removing the oil cup 40.

[0110] It can be understood that the magnetism of the first magnetic attraction portion and the second magnetic attraction portion are opposite.

[0111] refer to Fig.15 and Fig.16 The smoke collecting hood 20 includes a second flange 22, which is formed by extending a portion of the mounting opening 201 toward the inside of the smoke collecting hood 20, and the second flange 22 is formed along Fig.16 The second flange 22 is extended in the up and down directions as shown in the figure, and the second flange 22 is located above the oil containing cavity 400. The portion of the oil cup 40 away from the interior of the smoke hood 20 is higher than the other portions of the oil cup 40 and is located on the side of the second flange 22 away from the interior of the smoke hood 20. A magnetic attraction component 41 is provided on the portion of the oil cup 40 away from the interior of the smoke hood 20, and the second flange 22 is made of stainless steel, so that the magnetic attraction component 41 can be magnetically attracted to the second flange 22, so that the oil cup 40 can be installed on the smoke hood 20.

[0112] Under the action of external force, for example, the oil cup 40 is pulled out toward the outside of the smoke hood 20 , even if there is still magnetic force between the magnetic element 41 and the second flange 22 , the magnetic element 41 and the second flange 22 can still be separated from the magnetic connection, thereby removing the oil cup 40 .

[0113] In addition, the second flange 22 can also limit the oil cup 40, that is, the oil cup 40 is pushed into the interior of the smoke hood 20 from the installation opening 201, and after the portion of the oil cup 40 away from the interior of the smoke hood 20 contacts the second flange 22, the second flange 22 can limit the oil cup 40 from continuing to move, so that the installation position of the oil cup 40 is fixed. If the second flange 22 is not provided, even if the first magnetic attraction portion on the oil cup 40 can be magnetically connected with the second magnetic attraction portion on the smoke hood 20, and the oil cup 40 continues to be pushed into the interior of the smoke hood 20, once the thrust is greater than the magnetic force, the oil cup 40 will continue to move into the interior of the smoke hood 20, so that the oil cup 40 will not be installed in the correct position.

[0114] Exemplarily, the magnetic attraction member 41 may be a permanent magnet, or an electromagnet, or a demagnetized electromagnet, which is not specifically limited in this embodiment.

[0115] refer to Fig.17 , and combined with Fig.16In some embodiments, the range hood 1 further comprises a bracket 80, which is disposed inside the fume hood 20 and close to the mounting opening 201, and is connected to the fume hood 20. The bracket 80 is a frame structure, and a receiving space is formed between the frame structure and the fume hood 20, and the oil cup 40 is received in the receiving space. A support frame is further disposed on the side of the bracket 80 away from the mounting opening 201, and the support frame is located above the oil receiving chamber 400. The end of the oil guide component 50 is located on the support frame, so that the oil in the oil guide channel 500 can flow smoothly into the oil receiving chamber 400.

[0116] In this way, by providing the bracket 80 , the oil guide component 50 can be well supported, which is beneficial to the stability of the internal structure of the range hood 1 .

[0117] For example, the bracket 80 may be connected to the smoke hood 20 by means of threaded connection, snap connection, etc.

[0118] Continue to refer Fig.16 In some embodiments, the range hood 1 further includes a liquid level sensor 90, which is disposed on the top of the bracket 80, and the head of the liquid level sensor 90 is located above the oil containing cavity 400. The liquid level sensor 90 can monitor the oil amount information in the oil cup 40 in real time and transmit it to the control panel of the range hood 1, thereby reminding the user to clean the oil stains in the oil cup 40 in time as needed.

[0119] In this way, even if the oil cup 40 is designed to be inside the smoke hood 20, the user can still easily pay attention to the amount of oil in the oil cup 40 and clean it in time, and the oil will not overflow and pollute the stove.

[0120] In some embodiments, the liquid level sensor 90 is a non-contact liquid level sensor 90, which can monitor the amount of oil stains without contacting the oil stains. In this way, the liquid level sensor 90 is prevented from being wrapped by oil stains during use, which not only ensures the accuracy of the detection of the liquid level sensor 90 but also does not need to regularly clean the dirt on the liquid level sensor 90, making it easy to use.

[0121] In some embodiments, an oil level indicator light is provided on the control panel of the range hood 1, and the oil level information detected by the liquid level sensor 90 can be displayed in different colors. For example, the colors of the oil level indicator light are white and red. White indicates that the level of the oil stain in the oil containing cavity 400 is not full, and there is no need to clean the oil stain in the oil cup 40, and red indicates that the level of the oil stain in the oil containing cavity 400 is nearly full, and the oil stain in the oil cup 40 needs to be cleaned.

[0122] refer to Fig.18 , Fig.18 This is a flow chart of the oil volume display principle from the start to the end of the range hood operation.

[0123] First, the range hood 1 is turned on, the power board is powered on, and then the switch board light is on, and the color of the light is the color when the work was finished last time. Then, the user clicks the corresponding gear, the range hood 1 starts to operate, the liquid level sensor 90 starts to output signals, and the control chip calculates and determines the amount of oil in the oil cup 40 according to the input signal of the liquid level sensor 90, and displays the color.

[0124] Among them, continue to refer to Fig.18 The principle of displaying the oil quantity information detected by the liquid level sensor 90 in color is as follows: first, assuming that the oil reaches the maximum amount of oil that the oil cup 40 can hold, the corresponding measured value of the liquid level sensor 90 is N, and the real-time measured value of the oil in the oil cup 40 detected by the liquid level sensor 90 is n. When the measured value n≤5 / 6N, the indicator light is displayed in white, and when n>5 / 6N, the indicator light is displayed in red. In this way, the user can notice the oil quantity information of the oil in time during use, and can clean the oil cup 40 in time to ensure the normal use of the range hood 1.

[0125] When the user finishes cleaning, the liquid level sensor 90 re-detects the liquid level of the oil in the oil cup 40 .

[0126] For example, when the color of the oil level indicator light displayed on the control panel of the range hood 1 is red, the range hood 1 will issue a warning, such as flashing lights or sounding an alarm, which is not specifically limited in this embodiment. This setting further reminds the user to clean the oil cup 40 in time, so that the oil cup 40 will not overflow, causing secondary contamination of the stove top.
