Description
Technical Field
[0001] The utility model relates to the field of kitchen supplies, in particular to a front-end purification structure of a smoke hood. Background Art
[0002] Fume hoods are essential kitchen equipment, removing and purifying cooking fumes to reduce pollution and optimize the kitchen's working environment. In related technologies, fume hoods are equipped with electrostatic fume purifiers. These purify impurities from the air flowing through them by ionizing the oil vapor at high voltage and adsorbing the ions at low pressure.
[0003] A Chinese utility model patent with publication number CN220417424U discloses a flip-down fume hood integrated machine. A flip-down oil fume purification device is provided between the upper chamber and the lower chamber. When the oil fume purification device is in the flip-down state, the upper chamber and the lower chamber can be connected to each other. At the same time, the oil fume purification device can also be exposed under the fume hood body, so that the oil fume purification device can be cleaned and maintained more conveniently.
[0004] In the above structure, multiple shields for separating oil droplets and gas are installed below the secondary fume purification device. The shields are connected to the fume purification device. The overall weight of the shields is relatively large, and when cleaning the shields, they need to be removed again to clean the upper part. To this end, we designed a front-end purification structure for the fume hood. Utility Model Content
[0005] In order to solve the technical problem that the overall weight of the shield is large and the shield needs to be disassembled again before cleaning the top thereof, the utility model provides a front end purification structure of a smoke hood.
[0006] The utility model adopts the following technical solutions: a front-end purification structure of a smoke hood, comprising a smoke hood body, wherein the left bottom end of the smoke hood body is bent inward to form a bent portion, a connecting plate is integrally formed on the upper right side of the interior of the smoke hood body, and the left side of the connecting plate is continuously bent to form an abutment plate;
[0007] The bending portion is rotatably mounted with multiple sets of independently distributed mounting plates, the multiple sets of mounting plates are arranged in parallel, and a shield is installed on the upper end of each set of mounting plates. The number of mounting plates and the number of shields are set according to actual needs, wherein the number of mounting plates is one or more, a circular hole is opened on the top of each mounting plate, the shield is placed in the circular hole, and an oil net is slidably inserted into the interior of the mounting plate;
[0008] A plurality of locking members are arranged on the upper part of the mounting plate, and the locking members are connected to the abutting plate.
[0009] As a further improvement of the above solution, there is a gap between the inner side below the hood body and the bent part to form an oil storage tank. A plurality of linearly distributed oil leakage ports are penetrated and arranged below the left side of the mounting plate. The oil storage tank is communicated with the inside of the mounting plate through the oil leakage ports. The entire mounting plate and the oil screen are inclinedly installed. The oil on the oil screen can flow along its wall plate to the inner left wall of the mounting plate, and then be collected into the oil storage tank through the oil leakage ports.
[0010] As a further improvement of the above solution, both the left and right ends of the mounting plate are bent to form a U-shaped structure. The inner left end of the mounting plate is continuously bent three times to form a first folded edge. A first L-shaped bracket is arranged at the lower end of the first folded edge. Below the first folded edge, it is rotationally connected to the bent part through an L-shaped bracket and a pin. The L-shaped plate is arranged away from the lower part of the first folded edge. This enables the entire mounting plate to rotate around the pin, and the rotation range of the mounting plate is larger. Under the action of its own gravity, the mounting plate can be vertically downward and will not contact the bent part, avoiding causing pressure damage to it. Moreover, the lower part of the first folded edge also abuts against the upper surface of the bent part. When the mounting plate is integrally installed inside the hood body, the lower surface of the first folded edge abuts against the bent part, which can support the mounting plate, and a sealing structure is formed by pressing between the two, also improving the sealing performance, so that external oil fumes cannot enter the upper part inside the hood body through the gap between the two.
[0011] As a further improvement of the above solution, there is a gap between the left side wall of the abutting plate and the right outer wall of the mounting plate, and there is a tight press fit between the lower part of the top of the abutting plate and the upper surface of the mounting plate. The mounting plate can deflect around the hinge axis, thus facilitating the rotation of the mounting plate. When the mounting plate is closed, the upper part of the mounting plate and the lower part of the top of the abutting plate are tightly pressed together, improving the sealing performance, so that external oil fumes cannot enter the upper part inside the hood body through the gap between the two.
[0012] As a further improvement of the above solution, the locking member includes a pin rotatably installed at the top end inside the mounting plate. A wrench is fixed to the lower end of the pin. The upper end of the pin is placed above the mounting plate and a locking plate is fixed. The lower end surface of the locking plate abuts against the upper side surface of the abutting plate. The wrench and the locking plate are arranged in a staggered manner. When the wrench is rotated 90 degrees, the locking plate can rotate 90 degrees accordingly. At this time, the locking member releases the connection with the connecting plate, and the mounting plate can be turned downward as a whole around the hinge axis.
[0013] As a further improvement of the above solution, the left and right sides of the mounting plate are integrally bent to form second folded edges. The two second folded edges are bent inward to form connecting brackets. A rectangular oil fume port is formed between the two connecting brackets and the first and second folded edges. This oil fume port is used to communicate with the air inlet at the bottom of the oil screen, thereby facilitating the entry of oil fumes into the oil screen for the initial separation and purification of oil droplets and gas.
[0014] As a further improvement to the above solution, the length of the oil screen is shorter than the length of the oil smoke outlet on the mounting plate, and there is a gap between the left and right ends of the oil screen and the inner wall of the mounting plate, with the gap at the left end of the oil screen smaller than the gap at the right end. There is a gap of 3-5 cm between the oil screen and the top end of the mounting plate. The entire oil screen can be removed from the oil smoke outlet by sliding the right end of the oil screen to the right and lifting it, facilitating installation and removal of the oil screen.
[0015] A set of slides are provided at the front and rear ends of the lower surface of the oil net. The slides are continuously bent inward to form a U-shaped structure. The slide on the left side abuts against the left end of the oil fume outlet to prevent it from sliding to the left. The oil net itself is heavy. When the mounting plate and the oil net are installed at an angle, the oil net can be pressed against the inner bottom end of the mounting plate after installation, thereby improving the sealing.
[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. The utility model is to rotatably arrange one or more mounting plates under the smoke hood body, wherein the shield is mounted above the mounting plate, and the oil screen is plugged into the inside of the mounting plate. With the provided locking piece, the mounting plate can be quickly flipped over, thereby exposing the oil screen and the shield to the outside, and they can be disassembled separately, thereby facilitating their maintenance and cleaning, and avoiding the risk of the entire mounting plate falling off during disassembly. The locking piece is arranged above the inside of the mounting plate, which also avoids the locking piece from being opened due to misoperation, thereby improving safety.
[0018] 2. A folded edge 1 is provided below the mounting plate, which cooperates with the bent portion provided on the smoke hood body. When the mounting plate is installed as a whole inside the smoke hood body, the lower surface of the folded edge 1 and the bent portion abut against each other, which can support the mounting plate, and the two are pressed together to form a sealing structure, which also improves the sealing performance, so that external oil smoke cannot enter the upper part of the smoke hood body through the gap between the two.

[0029] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] Example:
[0031] Please combine Figures 1-8 The front-end purification structure of a smoke hood of this embodiment includes a smoke hood body 1, the left bottom end of the smoke hood body 1 is bent inward to form a bent portion 11, a connecting plate 2 is integrally formed on the upper right side of the smoke hood body 1, and the left side of the connecting plate 2 is continuously bent to form an abutting plate 21;
[0032] The bent portion 11 is rotatably mounted with multiple sets of independently distributed mounting plates 3, which are arranged in parallel. A shield 4 is mounted on the upper end of each set of mounting plates 3. The number of mounting plates 3 and the number of shields are set according to actual needs. There are one or more mounting plates. A circular hole is opened on the top of each mounting plate 3, and the shield 4 is placed in the circular hole. An oil screen 5 is slidably inserted into the interior of the mounting plate 3.
[0033] A plurality of locking members 6 are provided on the upper portion of the mounting plate 3 , and the locking members 6 are connected to the abutting plate 21 .
[0034] There is a gap between the inner side of the lower part of the smoke hood main body 1 and the bent part 11 to form an oil storage tank 12. A plurality of linearly distributed oil leakage ports 32 are penetrated and arranged below the left side of the mounting plate 3. The oil storage tank 12 is communicated with the inside of the mounting plate 3 through the oil leakage ports 32. The whole mounting plate 3 and the oil mesh 5 are inclinedly installed. The oil on the oil mesh 5 can flow along its wall plate to the inner left wall of the mounting plate 3, and then be collected into the oil storage tank 12 through the oil leakage ports 32.
[0035] Both the left and right ends of the mounting plate 3 are bent to form a U-shaped structure. The inner left end of the mounting plate 3 is continuously bent three times to form a first folded edge 31. The lower end of the first folded edge 31 is provided with a first L-shaped bracket. The lower part of the first folded edge is rotationally connected to the bent part 11 through the L-shaped bracket and a pin. The L-shaped plate is arranged away from the lower part of the first folded edge 31. This enables the whole mounting plate 3 to rotate around the pin, and the rotation range of the mounting plate 3 is larger. Under the action of its own gravity, the mounting plate 3 can be vertically downward and will not contact the bent part 11, avoiding causing pressure damage to it. Moreover, the lower part of the first folded edge 31 also abuts against the upper surface of the bent part 11. When the mounting plate 3 is integrally installed inside the smoke hood main body 1, the lower surface of the first folded edge 31 abuts against the bent part 11, which can support the mounting plate 3, and a sealing structure is formed by pressing between the two, also improving the sealing performance, so that external oil fume cannot enter the upper part inside the smoke hood main body 1 through the gap between the two. It should be noted that the connection method between the mounting plate 3 and the smoke hood main body 1 is not fixed, and it can also be connected by other methods as long as the mounting plate 3 can be vertically downward flipped.
[0036] There is a gap between the left side wall of the abutting plate 21 and the right outer wall of the mounting plate 3, and the lower part of the top of the abutting plate 21 is tightly pressed against the upper surface of the mounting plate 3. The mounting plate 3 can deflect around the hinge axis, which is convenient for the rotation of the mounting plate 3. When the mounting plate 3 is closed, the upper part of the mounting plate 3 and the lower part of the top of the abutting plate 21 are tightly pressed together, improving the sealing performance, so that external oil fume cannot enter the upper part inside the smoke hood main body 1 through the gap between the two.
[0037] The locking member 6 includes a pin rotatably installed at the top end inside the mounting plate 3. A wrench 61 is fixed to the lower end of the pin. The upper end of the pin is placed above the mounting plate 3 and a locking plate 62 is fixed. The lower surface of the locking plate 62 abuts against the upper side surface of the abutting plate 21. The wrench 61 and the locking plate 62 are arranged in a staggered manner. When the wrench 61 is rotated by 90 degrees, the locking plate 62 can rotate by 90 degrees accordingly. At this time, the locking member 6 releases the connection with the connecting plate 2, and the mounting plate 3 can be integrally flipped downward around the hinge axis.
[0038] The left and right sides of the mounting plate 3 are integrally bent to form a second folded edge 33, and the two second folded edges 33 are bent inward to form a connecting frame 34. A rectangular oil fume outlet 35 is formed between the two connecting frames 34 and the first folded edge 31 and the second folded edge 33. The oil fume outlet 35 is used to communicate with the air inlet at the bottom of the oil net 5, thereby facilitating the oil fume to enter the oil net 5 for the initial separation and purification of oil droplets and gas.
[0039] The length of the oil screen 5 is shorter than the length of the oil smoke outlet 35 on the mounting plate 3. There is a gap between the left and right ends of the oil screen 5 and the inner wall of the mounting plate 3. The gap at the left end of the oil screen 5 is smaller than the gap at the right end. There is a gap of 3-5 cm between the oil screen 5 and the top of the inner wall of the mounting plate 3. The right end of the oil screen 5 can be slid to the right and lifted to remove the entire oil screen 5 from the oil smoke outlet 35, making it easier to install and remove the oil screen 5.
[0040] A set of slides are provided at both the front and rear ends of the lower surface of the oil net 5. The slides are continuously bent inward to form a U-shaped structure. The slide on the left side abuts against the left end of the oil fume outlet 35, so that it will not slide to the left. The oil net 5 itself is relatively heavy. When the mounting plate 3 and the oil net 5 are both installed at an angle, the oil net 5 can be pressed against the inner bottom end of the mounting plate 3 after installation, thereby improving the sealing performance.
[0041] The implementation principle of the front-end purification structure of the smoke hood in the embodiment of the present application is as follows: when the shield 4 and the oil screen 5 need to be cleaned and repaired, the right end of the oil screen 5 is first slid to the right and lifted to remove the entire oil screen 5 from the oil smoke outlet 35;
[0042] After that, the wrenches 61 of the multiple locking members 6 in the mounting plate 3 can be rotated 90 degrees clockwise or counterclockwise. At this time, the locking plate 62 will rotate along with it, and then will be disconnected from the abutment plate 21. At this time, the mounting plate 3 can be flipped downward with the shaft pin as the axis. At this time, the entire mounting plate 3 and the corresponding shield 4 will also flip downward together.
[0043] After the mounting plate 3 and the corresponding shield 4 are turned downward, the shield 4 can be maintained and cleaned accordingly;
[0044] By rotatably setting one or more mounting plates 3 below the smoke hood body 1, wherein the shield 4 is mounted above the mounting plates 3, and the oil screen 5 is plugged into the inside of the mounting plates 3, and the locking member 6 is provided, the mounting plates 3 can be quickly flipped over, thereby exposing the oil screen 5 and the shield 4 to the outside, and they can be disassembled separately, thereby facilitating their maintenance and cleaning, and avoiding the risk of the entire mounting plate 3 falling off during disassembly. Moreover, the locking member 6 is arranged above the inside of the mounting plate 3, which also avoids the locking member 6 from being opened due to misoperation, thereby improving safety.
[0045] A folded edge 31 is provided below the mounting plate 3, which cooperates with the bent portion 11 provided on the smoke hood main body 1. When the mounting plate 3 is installed as a whole inside the smoke hood main body 1, the lower surface of the folded edge 31 and the bent portion 11 abut against each other, which can support the mounting plate 3, and the two are pressed together to form a sealing structure, which also improves the sealing performance, so that external oil smoke cannot enter the upper part of the smoke hood main body 1 through the gap between the two.
[0046] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
