Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a foot pad structure for a range hood and the range hood. Background Art

[0002] Currently, the installation of the range hood is to first fix the hook to the wall with expansion screws, and then hang the upper back of the range hood on the hook, and the lower back of the range hood is supported on the wall by the left and right feet. In this way, the range hood is hung on the wall by the hook on the back panel and the two feet.

[0003] Most of the existing foot pads are in the form of gaskets, which can buffer the vibration during the operation of the range hood, but the buffering effect is limited. In addition to vibration, the range hood will also generate heat during operation. If the heat can be dissipated in time, it will help to increase the service life of the range hood. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a foot pad structure for a range hood in view of the current status of the prior art, which can ensure the buffering effect and facilitate the heat dissipation of the range hood.

[0005] The second technical problem to be solved by the utility model is to provide a range hood with the above-mentioned foot structure.

[0006] The third technical problem to be solved by the utility model is to provide a range hood capable of sensing whether there is oil leakage or oil overflow in the oil cup.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a footrest structure for a range hood, comprising:

[0008] The elastic footing body has a first end surface for attaching to a wall and a second end surface for attaching to the back of the range hood body;

[0009] Features:

[0010] Independent closed chambers are spaced apart in the foot body, each of which is filled with heat-conducting gas, and at least the portion of the foot body located between the closed chamber and the second end face is a heat-conducting portion to conduct heat from the range hood.

[0011] The above-mentioned gas may be air, or nitrogen, argon, helium, etc.

[0012] The closed chamber filled with gas allows the foot body to effectively buffer the vibration generated when the range hood is working, and can effectively support the range hood so that the range hood will not be close to the wall and produce unnecessary friction noise. At the same time, the foot body can guide the heat generated by the range hood to assist the range hood in heat dissipation.

[0013] The above-mentioned closed chambers can be arranged in a honeycomb shape, or in a circular, rectangular or other array.

[0014] Preferably, the foot pad body is generally columnar, and each of the closed chambers extends along the axial direction of the column.

[0015] Preferably, the cross section of each of the closed chambers is hexagonal, triangular or circular.

[0016] Preferably, the cross section of each of the closed chambers is a regular hexagon or a regular triangle.

[0017] In the above scheme, in order to fix the foot body relative to the range hood, preferably, an axially through connection hole is provided in the center of the foot body for fasteners to pass through, and each of the closed chambers is distributed around the connection hole at intervals in the circumferential direction. The fasteners can pass through the connection hole of the foot body and then be connected to the back of the range hood to constrain the foot body to the range hood. The closed chambers are located around the connection hole so that the two do not interfere with each other and can ensure the support and buffering effects. The above fasteners include but are not limited to screws and the like.

[0018] Preferably, the closed chambers arranged at intervals in the circumferential direction form a group, and there are at least two groups, which are arranged at intervals in the radial direction of the columnar body.

[0019] Furthermore, for the two adjacent groups of closed chambers, the area of ​​the cross section of a single closed chamber located in the inner circle is smaller than the area of ​​the cross section of a single closed chamber located in the outer circle.

[0020] Furthermore, the cross-sectional shapes of each group of closed chambers are consistent.

[0021] In the above schemes, preferably, the gas is an inert, high pressure resistant, high temperature resistant, low density gas.

[0022] Preferably, the gas is nitrogen, argon or helium.

[0023] In the above solutions, preferably, the foot pad body is made of rubber material.

[0024] The technical solution adopted by the utility model to solve the second technical problem is: a range hood, including a range hood body, characterized in that it also has the above-mentioned foot structure, and the second end surface of the foot body is attached to the back of the range hood body.

[0025] Even if a foot structure is provided, the range hood will inevitably vibrate during operation. When there is a lot of oil in the oil cup body of the range hood, the vibration may cause the oil to overflow, which is sometimes difficult for the user to detect, causing the oil to drip onto the stove and affect the user experience. Therefore, in order to further solve the third technical problem mentioned above, preferably, it also includes an oil cup body, which is provided at the oil receiving position of the range hood body and has an oil receiving cavity with an opening facing upward;

[0026] In addition, a detection device is provided on the oil cup body for detecting whether there is oil on the outer side of the oil cup body.

[0027] Preferably, the oil cup body has an oil receiving cavity with an opening facing upward and a detection cavity located below the oil receiving cavity, and the detection cavity and the oil receiving cavity are independent of each other and separated by a middle partition;

[0028] The detection device comprises:

[0029] An emitting unit for emitting light and a receiving unit for receiving light are arranged side by side in the detection cavity;

[0030] A lens is disposed in the detection cavity, and has a light incident surface corresponding to the transmitting unit, a light emitting surface corresponding to the receiving unit, and a reflecting surface, wherein the reflecting surface is attached downward to the bottom wall of the detection cavity, and the reflecting surface is arranged to reflect the light entering the lens from the light incident surface to the light emitting surface, so that the receiving unit receives the light emitted by the transmitting unit;

[0031] At the same time, the bottom wall of the detection cavity is a transparent wall that can transmit light, so that when there is oil on the outer side of the transparent wall, at least part of the light entering the lens can be scattered away.

[0032] When the transparent wall of the oil cup body is dry (i.e., there is no oil on the transparent wall), the light intensity when there is no oil leakage can be known by detecting the light intensity received by the receiving unit. When there is oil on the transparent wall of the oil cup body, at least part of the light entering the lens is scattered, so that when the light intensity emitted by the transmitting unit remains unchanged, the light intensity received by the receiving unit decreases, and it can be known that the oil cup body has oil leakage or oil overflow at this time, and the user can be reminded to clean the oil cup. The more oil on the transparent wall, the lower the light intensity received by the receiving unit. By comparing the light intensity received by the receiving unit, the oil leakage and oil overflow in the oil cup can be judged.

[0033] Compared with the prior art, the utility model has the advantages that the closed chamber filled with gas allows the foot body to effectively buffer the vibration generated when the range hood is working, and can effectively support the range hood so that the range hood will not be close to the wall and produce unnecessary friction noise. At the same time, the foot body can guide the heat generated by the range hood to assist the range hood in heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] like Figures 1 to 7 As shown in the figure, a foot pad structure for a range hood and a preferred embodiment of the range hood of the utility model are shown, and the range hood comprises a range hood body 5, a foot pad structure and an oil cup structure.

[0043] The foot structure includes an elastic foot body 6 and screws (not shown in the figure).

[0044] The footing body 6 is a columnar body extending forward and backward as a whole, and is arranged on the back of the range hood body 5. The footing body 6 has a first end face 61 for attaching to a wall surface and a second end face 62 for attaching to the back of the range hood body 5. An axially penetrating connecting hole 64 is provided in the center of the footing body 6. A screw is connected to the range hood body 5 after passing through the connecting hole 64 as a fastener, so as to press the second end face 62 of the footing body 6 against the back of the range hood body 5. At the same time, the footing body 6 is provided with independent closed chambers 63 spaced along the circumferential direction at positions outside the connecting hole 64. Each closed chamber 63 extends along the axial direction of the columnar body, and the cross section of each closed chamber 63 is a regular hexagon. At the same time, the closed chambers 63 spaced along the circumferential direction are a group, and there are two groups, which are spaced along the radial direction of the columnar body and arranged inward and outward. The area of ​​the cross section of a single closed chamber 63 located in the inner circle is smaller than the area of ​​the cross section of a single closed chamber 63 located in the outer circle.

[0045] At the same time, each closed chamber 63 is filled with a heat-conducting gas (such as air, or an inert gas such as nitrogen, argon or helium), and the entire foot body 6 is made of a heat-conducting rubber material to conduct heat from the range hood.

[0046] In this way, the footrest body 6 of this embodiment can support the range hood body 5 to prevent the range hood body 5 from contacting the wall, and can also buffer the vibration of the range hood body 5 and dissipate the heat on the range hood body 5.

[0047] The oil cup structure includes an oil cup body 1 , a transmitting unit 2 , a receiving unit 3 and a lens 4 .

[0048] The oil cup body 1 is in the shape of a long strip extending from left to right, and is disposed below the range hood body 5. It has a bottom wall and side walls extending upward from the periphery of the bottom wall. The bottom wall and the side walls together form a concave cavity with an opening facing upward, and a partition 10 is disposed in the concave cavity. The partition 10 divides the concave cavity into two parts, namely, an oil receiving cavity 11 located above the partition 10 and opening upward (used to receive the oil flowing down from the range hood body 5), and a detection cavity 12 located below the partition 10. The detection cavity 12 is independent of the oil receiving cavity 11 and is separated by the middle partition 10. In this embodiment, the bottom wall of the oil cup body 1, that is, the bottom wall 121 of the detection cavity 12, is in the shape of an arc with high ends at the front and rear ends and low in the middle in the front and rear width direction.

[0049] The transmitting unit 2 is used to transmit infrared light, and the receiving unit 3 is used to receive infrared light. The transmitting unit 2 and the receiving unit 3 are arranged side by side in the detection cavity 12 one after the other.

[0050] The lens 4 is arranged in the detection cavity 12, below the transmitting unit 2 and the receiving unit 3, and has a light incident surface 41 corresponding to the transmitting unit 2, a light emitting surface 42 corresponding to the receiving unit 3, and a reflecting surface 43. The light incident surface 41 is a parabola arched toward the transmitting unit 2, so that the infrared light passing through the light incident surface 41 is a parallel light. The light emitting surface 42 is a parabola arched toward the receiving unit 3, so that the infrared light emitted from the light emitting surface 42 can be concentrated to the receiving unit 3. The upper surface of the lens 4 is concave between the light incident surface 41 and the light emitting surface 42 to form a notch 40 to separate the light incident surface 41 from the light emitting surface 42. The reflective surface 43 is a curved surface that matches the shape of the bottom wall 121 of the detection cavity 12. The reflective surface 43 is attached to the center of the width direction of the bottom wall 121 of the detection cavity. The reflective surface 43 is arranged to reflect the light entering the lens 4 from the light incident surface 41 to the light exiting surface 42, so that the receiving unit 3 receives the light emitted by the transmitting unit 2. At the same time, in this embodiment, the bottom wall 121 of the detection cavity 12 is a transparent wall that can transmit light, so that when there is oil on the outer side of the transparent wall, at least part of the light entering the lens 4 can be scattered. The path of the light is as follows Figure 1 Indicated by the arrow.

[0051] In this embodiment, the transmitting unit 2, the receiving unit 3 and the lens 4 form a group, and there are multiple groups arranged at intervals along the left-right direction.

[0052] In this embodiment, the receiving unit is for relative quantity measurement. When the surface of the oil cup body 1 is dry, there is air below the oil cup body 1. It is assumed that the infrared light emitted by the transmitting unit 2 is incident on the lens 4 in parallel and is 100% reflected back and received by the receiving unit.

[0053] When the outer surface of the oil cup body 1 is dry, the receiving unit is first initialized, from which the light intensity received by the receiving unit under a fixed emission current can be obtained. In this case, the light intensity is usually relatively high.

[0054] When there are oil droplets on the outer surface of the oil cup body 1 (the refractive index of the oil droplets and air for light is different), the light incident on the lens 4 is partially scattered, and the intensity of the light received by the receiving unit after reflection becomes less. The larger the oil droplets, the less the intensity of the reflected light. By comparing the light intensity received when the outer surface of the oil cup is dry, the size and amount of the oil droplets on the oil cup can be obtained. Then the user is reminded to clean the oil cup.

Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
