[0041] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0042] Example 1

[0043] refer to Figure 1-3 The present embodiment provides a range hood, including a panel assembly 4 and an inner cover assembly 2, wherein the panel assembly 4 includes a panel 41 and a lining plate 42, the panel 41 is a glass panel or a metal panel, and the lining plate 42 is fixedly connected to the back of the panel 41 by bonding. When the panel 41 is a metal panel, the lining plate 42 can also be fixedly connected to the back of the panel 41 by welding, riveting or screws.

[0044] The inner cover assembly 2 is detachably connected to the back of the lining plate 42. In this embodiment, the inner cover assembly 2 and the panel assembly 4 are enclosed to form a relatively sealed installation cavity 204. The installation cavity 204 can be used to install the electrical components of the range hood, which include lighting components and / or switch components. In this way, the inner cover assembly 2 serves as a protective cover to prevent the electrical components from being disturbed by oil smoke, and at the same time prevents the oil stains on the wind cabinet assembly from directly dripping down onto the lighting components and / or switch components. At this time, the connection strength between the inner cover assembly 2 and the panel assembly 1 is relatively weak, and a gap will be left between the inner cover assembly 2 and the panel assembly 1. In addition, the overall strength of the inner cover assembly 2 itself is insufficient, and displacement is easy to occur during transportation vibration tests and drop tests.

[0045] In order to solve the above-mentioned shortcomings, the range hood also includes a clamping structure and / or a reinforcing bracket 3, and the clamping structure is arranged between the lower end of the inner cover assembly 2 and the lining plate 42. In this way, through the clamping structure, the bottom front end of the inner cover assembly 2 can be tightly attached to the back side of the lining plate 42 to reduce the gap between the inner cover assembly 2 and the panel assembly 1, thereby avoiding the formation of condensed oil in the gap due to oil smoke and causing oil leakage. At least one reinforcing bracket 3 is provided in the inner cover assembly 2. In the present embodiment, there are two reinforcing brackets 3, and each reinforcing bracket 3 is respectively connected to the inner cover assembly 2 and the lining plate 42. Thus, by reinforcing the bracket 3, firstly, the connection strength and connection firmness reliability between the panel assembly 4 and the inner cover assembly 2 are increased, and displacement of the inner cover assembly 2 and friction with the lining plate 42 during the transportation vibration test or the drop test are avoided, and the coating of the lining plate 42 is prevented from being scratched and causing rust; secondly, the strength of the inner cover assembly 2 is enhanced, and displacement of the inner cover assembly 2 and collision with the side plate of the smoke hood of the range hood during the drop test are avoided, causing deformation; thirdly, the bottom front end of the inner cover assembly 2 can be tightly attached to the back side of the lining plate 42, and a gap between the lining plate 42 and the bottom of the inner cover assembly 2 can be avoided, thereby avoiding the problem of oil dripping caused by condensed oil.

[0046] refer to Figure 2 Specifically, the clamping structure includes a snap 421. A front folding edge 211 extending upward is provided at the bottom front end of the inner cover assembly 2. A plurality of snaps 421 arranged at intervals in the left-right direction are provided at the lower end of the back of the lining plate 42. In this embodiment, the snap 421 is in a "Z" shape, which is formed by extending backward and bending multiple times after a part of the lining plate 42 is cut and separated from the lining plate 42. During installation, the front folding edge 211 is inserted from bottom to top between the snap 421 and the back of the lining plate 42. At this time, the free end of the snap 421 is located behind the front folding edge 211, and the snap 421 presses the front folding edge 211 against the back of the lining plate 42. In this way, the front folding edge 211 of the inner cover assembly 2 is closely attached to the lining plate 42, avoiding a gap between the front folding edge 211 and the lining plate 42, thereby avoiding the problem of oil leakage caused by condensed oil.

[0047] A plurality of limiting portions 422 are arranged at intervals in the left-right direction and extend backward on the back of the lining plate 42. In this embodiment, the limiting portion 422 is a hollow protrusion with an open bottom, which is formed by stamping backward integrally from the local lower end of the lining plate 42 after being cut and separated from the lining plate 42. Each limiting portion 422 is located above the front folding edge 211 and abuts against the upper edge of the front folding edge 211, and is used to limit the front folding edge 211, so as to achieve the upper limit of the installation of the inner cover assembly 2.

[0048] refer to Figure 3-6Specifically, the reinforcing bracket 3 is in a "7"-shaped structure, and the upper end of the reinforcing bracket 3 is respectively connected to the lining plate 42 and the rear side wall of the inner cover assembly 2, and the lower end of the reinforcing bracket 3 is detachably connected to the bottom of the inner cover assembly 2, thus forming a triangular reinforcement structure to enhance the strength of the entire assembly. When the bottom of the inner cover assembly 2 is connected and fixed to the lower end of the reinforcing bracket 3, the bottom front end of the inner cover assembly 2 (i.e., the front folding edge 211) can be tightly attached to the back of the lining plate 42, avoiding the formation of a gap between the lining plate and the inner cover assembly, thereby avoiding the occurrence of condensed oil; in addition, when the rear side wall of the inner cover assembly 2 is connected and fixed to the rear end of the reinforcing bracket 3, the strength of the rear side wall of the inner cover assembly 2 is enhanced and its displacement is restricted, thereby avoiding the rear side wall of the inner cover assembly 2 from scratching off the lining plate coating after the vibration test, causing the lining plate to rust.

[0049] More specifically, a first mounting portion 423 extending backward is formed integrally on the left and right sides of the upper end of the back side of the lining plate 42, and a first folded edge 31 extending toward the first mounting portion 423 is formed integrally on the front side of the upper end of the reinforcing bracket 3. The first folded edge 31 is fixedly connected to the first mounting portion 423 to form a first connection. Figure 4-6 In this way, the front end of the reinforcing bracket 3 is fixedly mounted on the panel assembly 1. In this embodiment, the first mounting portion 423 is a convex bulge, which is formed by a partial integral backward stamping of the lining plate 42. The side of the convex bulge close to the reinforcing bracket 3 is opened to form a side opening. During installation, the first folded edge 31 is inserted into the convex bulge through the side opening of the convex bulge, and the first folded edge 31 is fixedly connected to the convex bulge by welding, bonding or screws. Of course, the first folded edge 31 can also be attached to the back of the convex bulge and fixedly connected to the convex bulge by welding, bonding or screws. In this case, the side opening of the convex bulge can be omitted or not omitted.

[0050] A connecting portion 208 extending upward and located inside the inner cover assembly 2 is integrally formed at the bottom of the inner cover assembly 2 at a position corresponding to the reinforcing bracket 3. The lower end of the reinforcing bracket 3 is detachably connected to the connecting portion 208 to form a second connection. Figure 3 and Figure 7 In this way, the lower end of the reinforcing bracket 3 is reliably connected to the bottom of the inner cover assembly. In this embodiment, the connecting portion 208 is an elastic connecting piece, which is formed by cutting and separating a part of the bottom of the inner cover assembly 2 from the bottom of the inner cover assembly 2 and bending upward as a whole. A screw hole 33 is provided at the position of the lower end of the reinforcing bracket 3 corresponding to the elastic connecting piece. When installing, a fastener (such as a screw) is used to transversely penetrate the screw hole 33 of the elastic connecting piece and the reinforcing bracket 3. Since the elastic connecting piece has a certain deformation ability, even if the lower end of the reinforcing bracket 3 is offset, it can ensure that the lower end of the reinforcing bracket 3 is reliably and detachably connected to the elastic connecting piece.

[0051] A second folded edge 32 extending outward is integrally formed on the rear side of the upper end of the reinforcing bracket 3. In this embodiment, the second folded edge 32 extends in the same direction as the first folded edge 31. Of course, it can also be designed to be in the opposite direction. When installed, the second folded edge 32 is attached to the rear side wall of the inner cover assembly 2, and the second folded edge 32 and the inner cover assembly 2 are detachably connected by multiple fasteners (such as screws) to form a third connection. Figure 3 and Figure 7 In this way, the rear end of the reinforcing bracket 3 is reliably connected to the rear side wall of the inner cover assembly. It can be seen that the first connection point, the second connection point and the third connection point are located at different positions, and the connection line of the three connections forms a triangular reinforcement structure, which is conducive to improving the inherent strength and installation strength of the inner cover assembly.

[0052] refer to Figure 7 In this embodiment, arc flanges are formed integrally on the upper and lower sides of the rear end of the reinforcing bracket 3, respectively. The arc flanges have the same orientation as the second folding edge 32. The second folding edge 32 is located between the two arc flanges, and the upper and lower ends of the second folding edge 32 are formed integrally with the two arc flanges, respectively, so as to improve the strength of the rear side of the reinforcing bracket 3 through the cooperation between the second folding edge 32 and the two arc flanges. A front flange 34 extending outward and located below the first folding edge 31 is formed integrally on the front side of the lower end of the reinforcing bracket 3. The front flange 34 is in an arc shape, and its orientation is the same as that of the first folding edge 31, and is used to improve the strength of the front side of the reinforcing bracket 3. In addition, a press-type structure is provided on the reinforcing bracket 3, and the press-type structure includes a first press-type 351 and a second press-type 352. The first press-type 351 is provided on the reinforcing bracket 3 and is located between the second folding edge 32 and the front flange 34. The second press-type 352 is triangular and provided between the first folding edge 31 and the reinforcing bracket 3.

[0053] refer to Figure 1-3 and Figure 7-8 Specifically, a mounting cavity 204 is formed between the inner cover assembly 2 and the panel assembly 4, a bottom mounting hole 203 and / or at least one air inlet 201 are provided at the bottom of the inner cover assembly 2, the air inlet 201 is connected to the mounting cavity 204 and is used to allow oil smoke to pass through, and the bottom mounting hole 203 is connected to the mounting cavity 204 and is used to install the lighting assembly of the range hood. Correspondingly, an air outlet 202 connected to the mounting cavity 204 is provided at a position of the rear side wall of the inner cover assembly 2 corresponding to the air inlet 201, so that an oil smoke channel is formed in the inner cover assembly to improve the smoking effect.

[0054] An oil discharge port is provided at the lower end of the rear side wall of the inner cover assembly 2, and the oil discharge port includes a first oil outlet 205 and / or a second oil outlet 206. The first oil outlet 205 is connected to the air inlet chamber 2041, and the second oil outlet 206 is connected to the smoke isolation chamber 2042. Thus, through the first oil outlet 205, it is convenient to discharge the oil droplets formed in the air inlet chamber 203 out of the air inlet chamber 203 in time, so as to prevent the oil droplets from accumulating and leaking out of the air inlet chamber 203 and leaking into the smoke isolation chamber 204, thereby causing oil leakage; through the second oil outlet 206, it is convenient to discharge the oil droplets leaking into the smoke isolation chamber 204 out of the smoke isolation chamber 204 in time. In addition, an oil guide portion 207 is provided at the rear end of the bottom of the inner cover assembly 2, and the oil guide portion 207 is located below the air outlet 202 and the oil discharge port, and is used to receive the oil stains flowing down from the oil discharge port, so as to guide the oil stains to the inside of the smoke collecting hood of the range hood.

[0055] refer to Figure 1-7 Specifically, a second mounting portion 424 extending backward is respectively provided in the middle of the left and right ends of the lining plate 42. In this embodiment, the second mounting portion 424 is a mounting edge, which is formed by bending backward integrally after a part of the lining plate 42 is cut and separated from the lining plate. The inner cover assembly 2 is covered in the two second mounting portions 424, and the left and right side walls of the inner cover assembly 2 are detachably connected to the two second mounting portions 424. In this way, the inner cover assembly 2 can be detachably mounted on the back of the panel assembly 1, and the two second mounting portions 424 can be hidden in the inner cover assembly 2, which is conducive to improving the overall aesthetics of the appearance.

[0056] refer to Figure 7-8 Specifically, the inner cover assembly 2 includes an inner cover body 21, which includes an inner cover bottom plate 213, two inner cover side plates 212 and a front folding edge 211. The inner cover bottom plate 213 constitutes the bottom of the inner cover assembly 2, and an air inlet 201 and / or a bottom mounting hole 203 are provided on the inner cover bottom plate 213. The left and right ends of the inner cover bottom plate 213 are respectively bent upwards to form two inner cover side plates 212, and the two inner cover side plates 212 constitute the left and right side walls of the inner cover assembly 2. The two inner cover side plates 212 are respectively detachably connected to the two second mounting portions 424 of the lining plate 42. The integral front end of the inner cover bottom plate 213 is bent upwards to form a front folding edge 211, and the front folding edge 211 is in close contact with the back of the lining plate 42.

[0057] The inner cover body 21 also includes a rear folded edge 214. The rear end of the inner cover bottom plate 213 is integrally bent upward to form the rear folded edge 214. An air outlet 202 is provided at the position of the rear folded edge 214 corresponding to the air inlet 201. In the present embodiment, the upper end edge of the rear folded edge 214 is lower than the top of the inner cover side plate 212. At this time, the rear folded edge 214 constitutes the lower part of the rear side wall of the inner cover group. The inner cover body 21 has an opening that opens backward and upward, and the opening is located above the rear folded edge 214.

[0058] The inner cover assembly 2 also includes an inner cover back plate 22, which is respectively connected to the back and top of the inner cover body 21 and covers the opening of the inner cover body 21. Specifically, the left and right ends of the inner cover back plate 22 are respectively connected to the two inner cover side plates 212 of the inner cover body 21, and the lower end of the inner cover back plate 22 is connected to the rear folded edge 214 of the inner cover body 21, and the top front side of the inner cover back plate 22 is abutted against the back of the lining plate 42. At this time, the lining plate 42, the inner cover body 21 and the inner cover back plate 22 together enclose a mounting cavity 204.

[0059] In addition, the inner cover assembly 2 also includes an oil guide plate 24, which includes an oil guide portion 207 and a connecting portion (not shown in the figure). The oil guide portion 207 is arranged at the rear end of the bottom of the inner cover body 21 and is located directly below the oil discharge port and the air outlet 202, and is used to receive the oil stains flowing down from the oil discharge port and the air outlet 202, and guide the oil stains to the inside of the smoke collecting hood of the range hood. The connecting portion is fixedly connected to the back of the rear folding edge 214 of the inner cover body 21 and is located outside the air outlet 202 and the oil outlet. The lower end of the connecting portion is fixedly connected to the oil guide portion 207, so that the oil guide portion 207 can be reliably installed at the rear end of the bottom of the inner cover bottom plate 213 of the inner cover body 21 through the connecting portion. Of course, the connecting portion can also be omitted, and the oil guide portion 207 can be directly installed at the rear end of the bottom of the inner cover bottom plate 213 instead.

[0060] Example 2

[0061] The difference between this embodiment and embodiment 1 is that the inner cover assembly 2 omits the inner cover back plate 22. Specifically, the inner cover assembly 2 includes an inner cover body 21, and the inner cover body 21 includes an inner cover bottom plate 213, two inner cover side plates 212, a front folding edge 211 and a rear folding edge 214. In this embodiment, the upper end of the rear folding edge 214 extends forward and upward to the top of the inner cover side plate 212, and is respectively abutted or connected to the top of the inner cover side plate 212 and the upper end of the back of the lining plate 42. At this time, the rear folding edge 214 constitutes the entire rear side wall of the inner cover assembly, that is, the rear folding edge 214 completely replaces the inner cover back plate 22, and the installation cavity 2046 is formed by the inner cover body 21 and the lining plate 42.

[0062] It can be seen that by extending the rear folded edge 214 of the inner cover body 21 toward the front and upward, the rear folded edge 214 can be used to replace the inner cover back plate 22, thereby achieving the purpose of eliminating the inner cover back plate 22. Compared with the inner cover back plate 22, the connection structure between the rear folded edge 214 and the lower end of the inner cover back plate 22 can be omitted, making the overall structure of the inner cover assembly simpler.

[0063] Example 3

[0064] refer to Figure 9-10, the difference between this embodiment and embodiment 1 or 2 is that it further includes an isolation cover 1, and the isolation cover 1 has a cavity 101 that opens downward and backward. An isolation cover 1 is installed at a position corresponding to the air inlet 201 in the installation cavity 204, and the isolation cover 1 is arranged outside the air inlet 201 and connected to the inner cover assembly 2. The isolation cover 1 separates the installation cavity 204 into an air inlet cavity 2041 and a smoke isolation cavity 2042. The air inlet cavity 2041 is respectively connected to the air inlet 201 and the air outlet 202 to form an oil fume passage, and the smoke isolation cavity 2042 is connected to the bottom installation hole 203. It can be seen that by providing the isolation cover 1, the installation cavity 204 is separated into the air inlet cavity 2041 and the smoke isolation cavity 2042, and the oil and electricity are separated, so that the oil fume is not easy to enter the smoke isolation cavity 2042, and the lighting assembly and / or switch assembly in the smoke isolation cavity 2042 is protected from the interference of oil fume, which is conducive to improving the service life of the lighting assembly and / or switch assembly.

[0065] refer to Figure 10-13 In this embodiment, the isolation cover 1 includes a top plate 11, a front plate 12 and two side plates 13 arranged opposite to each other. The top plate 11, the front plate 12 and the two side plates 13 are enclosed to form a cavity 101 with a downward and rearward opening, wherein the top plate 11 constitutes the top of the cavity 101, the front plate 12 constitutes the front side wall of the cavity, and the two side plates 13 constitute the left and right side walls of the cavity 101. An oil guide portion 111 extending backward and downward is integrally formed at the top rear end of the isolation cover 1, that is, an oil guide portion 111 extending backward and downward is integrally formed at the rear end of the top plate 11, and the angle β between the oil guide portion 111 and the top plate 11 is 120 to 160°, preferably 150±5°. The free end of the oil guide portion 111 passes through the air outlet 202 and extends to the rear of the air outlet 202, and is used to guide the oil smoke and oil droplets in the isolation cover into the smoke collecting hood.

[0066] It is particularly noted that the isolation cover 1 can be switched between an open state and a closed state, and the oil guide portion 111 is arranged to be tilted downward and rearward when the isolation cover is in the open state and the closed state. When the range hood is in the open state, the isolation hood 1 is also in the open state. At this time, the isolation hood 1 is arranged with a high front end and a high rear end, and the oil guiding part 111 is arranged to be inclined toward the rear and downward in the open state, and it forms a first angle θ1 with the horizontal plane. In this way, it is convenient to quickly guide the oil smoke and oil droplets in the isolation hood into the smoke collecting hood; conversely, when the range hood is in the closed state, the isolation hood 1 is also in the closed state. At this time, the isolation hood 1 is arranged with a low front end and a high rear end, and the oil guiding part 111 is arranged to be inclined toward the rear and downward in the closed state, and it forms a second angle θ2 with the horizontal plane, wherein the second angle θ2 is smaller than the first angle θ2. In this way, the oil droplets formed on the oil guiding part 111 cannot flow back into the oil separator 1, and finally drip into the smoke collecting hood along the oil guiding part 111, thereby minimizing the oil droplets inside the oil separator 1 and solving the problem of oil dripping caused by a large amount of oil droplets accumulating inside the isolation hood 1.

[0067] refer to Figure 12-13 Specifically, the oil guide portion 111 is formed by the right end of the top plate 11 being bent toward the rear and downwards, and notches 112 are respectively provided on the left and right sides of the free end of the oil guide portion 111. The notch 112 is in an inverted "V" shape. Of course, the notch 112 can also be designed to be in an inverted "W" shape, an inverted "U" shape, or an inverted "mountain" shape. Therefore, under the action of the notch 112, the oil on the oil guide portion 111 is quickly converged to the lower edge of the oil guide portion 111 to form oil droplets, and the oil droplets on the lower edge of the oil guide portion 111 are prevented from spreading to the left and right sides, so that the oil droplets are quickly dropped into the smoke collecting hood of the range hood.

[0068] Specifically, the rear ends of the two side panels 13 are respectively bent toward the outside of the cavity 101 to form rear flanges 131. In this embodiment, the rear flanges 131 are arranged to be inclined toward the rear and downward, and the rear flanges 131 are connected to the lower end of the rear side wall of the inner cover assembly 2, so that the rear end of the isolation cover 1 is reliably connected to the rear side wall of the inner cover assembly 2. In addition, the inner cover assembly 2 also includes a fixing bracket 23, and at least one fixing bracket 23 is provided in the air inlet cavity 203 and is located in front of the air inlet 201. The front plate 12 of the isolation cover 1 is detachably connected to the inner cover bottom plate 213 of the inner cover body 21 through the fixing bracket 23, so that the front end of the isolation cover 1 is fixedly installed on the bottom front end of the inner cover assembly 2.
