[0002] Smokeless duct range hoods are usually composed of fans, filters, electronic controllers, etc. When cooking in the kitchen, smokeless duct range hoods can circulate indoor air and then discharge it back into the room, while filtering out the oil smoke and odor in it, making the indoor air fresher. Since this type of range hood does not require the installation of exhaust pipes and does not discharge oil smoke to the outside, it is widely used in the catering industry.

[0003] At present, in this type of smokeless range hood, the filter is usually installed in a box, and the box is then installed above the smoke collecting hood, and the cavity of the box is connected to the hood, so that the oil smoke absorbed into the hood is introduced into the box for purification through the filter. When this type of range hood is installed in the kitchen, the hood needs to be installed above the cooking area, and then the box is fixed to the upper side of the hood. The installation is more troublesome, and space needs to be left above the hood for the box, resulting in a larger space occupied by the entire range hood. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0022] See also Figure 1-Figure 6 The thin smokeless duct range hood of this embodiment includes a cover body 1, a filter device 2 and an exhaust device 3. The cover body 1 is provided with a cavity 11, and the filter device 2 is arranged in the cavity 11. The cover body 1 is provided with an air inlet 12 and an air outlet 13, and the air inlet 12 and the air outlet 13 are both connected to the cavity 11. The filter device 2 is arranged between the air inlet 12 and the air outlet 13. The exhaust device 3 is arranged in the cavity 11 and drives the gas in the cavity 11 to flow to the air outlet 13 for discharge.

[0023] When the utility model is installed, the air inlet 12 faces the cooking area. When in use, the exhaust device 3 is turned on to suck the air in the cooking area into the cavity 11 of the cover body 1 through the air inlet 12. The air moves to the air outlet 13 through the filter device 2. When the user cooks under the cover body 1 and generates oil smoke, the tiny particles and gas in the oil smoke are mixed in the air and sucked into the cover body 1. The filter device 2 purifies the tiny particles and gas in the air, and the purified air is discharged back into the kitchen through the air outlet 13, so that the oil smoke purification effect of the range hood is achieved. Since the filter device 2 in the utility model is installed in the cavity 11 of the cover body 1, there is no need to assemble an additional box for installing the filter device 2, so the space occupied by the range hood can be reduced, thereby reducing the depth and height required for installation, and it can be suitable for kitchens with smaller depth and height.

[0024] See also Figure 2 , Figure 3 A partition 14 is vertically arranged in the front-to-back direction in the cover body 1, and the upper end, lower end and rear end of the partition 14 are all in contact with the inner wall of the cover body 1. The air outlet 13 and the air inlet 12 are respectively arranged on the left and right sides of the partition 14. The filter device 2 is provided with a plurality of them and is arranged side by side on the left and right sides of the partition 14, and the air inlet 12 and the air outlet 13 are located on the rear side of the filter device 2.

[0025] In this embodiment, the air inlet 12 is located on the lower side of the cover body 1 , and the air outlet 13 is located on the upper side of the cover body 1 .

[0026] The oil smoke mixed gas enters the cavity 11 on the right side of the partition 14 through the air inlet 12 and moves forward through the filter device 2 on the right side of the partition 14, and then the mixed gas bypasses the partition 14 and passes through the filter device 2 on the left side of the partition 14 to enter the cavity 11 on the left side of the partition 14. Therefore, in the utility model, the partition 14 and the filter device 2 are used to divide the cover body 1 into three cavities 11, namely, the air inlet chamber 15, the air outlet chamber 17 and the transition chamber 16 located on the front side. The mixed air passes through the air inlet chamber 15, the transition chamber 16 and the air outlet chamber 17 in turn, and the mixed gas is purified twice by the filter devices 2 at two positions between the air inlet chamber 15 and the transition chamber 16 and between the transition chamber 16 and the air outlet chamber 17, thereby improving the purification effect of the filter device 2; at the same time, by setting the partition 14, the filter devices 2 are placed side by side on the left and right, which can make the structure inside the cover body 1 more compact, thereby reducing the front and rear width required for the cover body 1, which is suitable for kitchens with relatively narrow space.

[0027] See also Figure 2 , Figure 3 The exhaust device 3 is arranged on the left side of the partition 14, and the exhaust port 31 of the exhaust device 3 is adapted to be connected with the air outlet 13.

[0028] In the present invention, the exhaust device 3 adopts a turbo fan, which has the advantage of large air volume, thereby accelerating the suction of oil smoke and improving the purification rate of oil smoke. Since the air entering the air outlet chamber 17 on the left side of the partition 14 has been adsorbed and purified by the filter device 2, arranging the exhaust device 3 at this position can reduce the probability of the exhaust device 3 contacting with oil smoke, thereby reducing the rate at which the exhaust device 3 is contaminated by oil smoke and reducing the cleaning frequency of the exhaust device 3.

[0029] See also Figure 5 A plurality of air inlets 12 are arranged side by side on the left and right sides, and an oil fume separation plate 4 is adapted to be arranged inside the air inlet 12 .

[0030] When the oil fume separation disk 4 rotates at a high speed, it can effectively intercept the oil fume particles passing through it, so that the oil fume particles with larger particle sizes can be separated from the oil fume mixed gas first under the action of the oil fume separation disk 4, and the remaining oil fume particles with smaller particle sizes and oil fume gas are then adsorbed and purified by the filter device 2. Since the filter device 2 is installed in the cover body 1, the disassembly and cleaning operations are relatively troublesome. The oil fume separation disk 4 can reduce the speed of oil fume dirt adhesion and accumulation on the filter device 2, thereby reducing the frequency of cleaning the filter device 2.

[0031] See also Figure 5 , Figure 6The lower side surface of the cover body 1 and the bottom surface of the cavity 11 in the cover body 1 are in an inclined state with the front end higher and the rear end lower. A plurality of oil leakage holes 18 are opened on the rear end of the lower side surface of the cover body 1, and an oil groove 19 is provided at the rear end of the cover body 1. The oil groove 19 is located below the oil leakage hole 18, and the lower end of the oil groove 19 is provided with an oil outlet 191 with a valve connected to the oil groove 19.

[0032] After the filter device 2 has been used for a period of time, a large amount of oil smoke and dirt will be absorbed by the filter device 2, and the liquid oil will drip downward onto the bottom surface of the cavity 11. Since the lower side surface of the cover body 1 is in an inclined state, the bottom surface of the cavity 11 is also in an inclined state. The oil slides under the action of its own gravity and falls into the oil tank 19 through the oil leakage hole 18 for collection, thereby preventing the oil from accumulating in the cavity 11 and affecting the normal operation of the utility model. After a certain amount of oil is collected in the oil tank 19, the oil in the oil tank 19 is released by opening the valve on the oil outlet 191, thereby facilitating the maintenance of the utility model.

[0033] See also Figure 4 , Figure 6 A plurality of baffles 5 are arranged side by side on the lower side of the cover body 1. The baffles 5 are parallel to the lower side of the cover body 1. The front and rear ends of the baffles 5 are both mounted on the cover body 1. The rear end of the baffles 5 is located above the oil groove 19, and the air inlet 12 is located on the inner side of the baffles 5.

[0034] When the oil fume separation plate 4 intercepts the oil fume particles to form oil droplets and throws them away, the oil droplets adhere to the lower side of the cover body 1 and slide into the oil groove 19 under the action of their own gravity. The oil droplets thrown onto the baffle 5 by the oil fume separation plate 4 will also slide along the baffle 5 into the oil groove 19, so that the oil droplets are collected by the oil groove 19 to reduce the pollution of the oil droplets to other locations.

[0035] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
