DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-Figure 6 The chassis structure of the thin smokeless duct range hood in this embodiment includes a cover body 1, which is a hollow structure. The cavity 2 of the cover body 1 includes an air inlet chamber 21, a transition chamber 22 and an air outlet chamber 23 that are connected in sequence. An air inlet 11 and an air outlet 12 are provided on the cover body 1. The air inlet 11 is connected to the air inlet chamber 21, and the air outlet 12 is connected to the air outlet chamber 23. A first mounting position 24 for mounting a filter device 8 is provided in the transition chamber 22, and a second mounting position 25 for mounting a fan 9 is provided in the air outlet chamber 23.

[0024] The utility model can adapt the filter device 8 to be installed on the first installation position 24, and adapt the fan 9 to be installed on the second installation position 25 and connect the air supply port of the fan 9 with the air outlet 12, so that when the fan 9 is working, an air flow is formed in the cavity 2 of the cover body 1, which is sucked in by the air inlet 11 and passes through the air inlet chamber 21, the transition chamber 22 and the air outlet chamber 23 in sequence and finally discharged through the air outlet 12. Therefore, when the user cooks near the air inlet 11 or below the air inlet 11 and generates oil smoke, the oil smoke mixed gas will be sucked into the cover body 1 through the air inlet 11, and the oil smoke mixed gas can absorb and purify the oil smoke particles and oil smoke gas when passing through the filter device 8 in the transition chamber 22, and the purified air is then discharged back into the kitchen through the air outlet 12, thereby achieving the oil smoke purifying effect of the utility model.

[0025] Since the filter device 8 for adsorbing and purifying oil smoke in the utility model is installed in the cavity 2 of the cover body 1 through the first installation position 24, there is no need to additionally assemble a box for installing the filter device 8, so the depth required for installation can be reduced, so that it is suitable for kitchens with smaller depth and height.

[0026] See also Figure 2 , Figure 3 A partition 3 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 3 are all in contact with the inner wall of the cover body 1. The air outlet chamber 23 and the air inlet chamber 21 are respectively located on the left and right sides of the partition 3, and the transition chamber 22 is located on the front side of the partition 3. There are several first mounting positions 24 and they are arranged side by side on the left and right sides of the partition 3, and the air inlet 11 and the air outlet 12 are located on the rear side of the first mounting position 24.

[0027] In this embodiment, the air inlet 11 is located on the lower side of the cover body 1 , and the air outlet 12 is located on the upper side of the cover body 1 .

[0028] The oil fume mixture passes through the air inlet chamber 21, the transition chamber 22 and the air outlet chamber 23 in sequence, and is purified twice by the filter devices 8 at two positions between the air inlet chamber 21 and the transition chamber 22 and between the transition chamber 22 and the air outlet chamber 23, thereby improving the purification effect of the filter device 8; at the same time, by arranging the partition 3 so that the filter devices 8 are placed side by side on the left and right, the structure inside the cover body 1 can be made more compact, thereby reducing the front and rear width required for the cover body 1, and is suitable for kitchens with relatively narrow space.

[0029] See also Figure 2 , Figure 3 The air inlets 11 are arranged side by side in a plurality, which increases the range of the hood body 1 for lateral suction of oil smoke, thereby reducing the probability of the oil smoke escaping to the outside of the hood body 1.

[0030] In this embodiment, the air inlet 11 is circular, and an oil fume separation disk 5 can be installed in each air inlet 11. When the oil fume separation disk 5 rotates at 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 5, and the remaining oil fume particles with smaller particle sizes and oil fume gas are then adsorbed and purified by the filter device 8. Since the filter device 8 is installed in the cover body 1, the disassembly and cleaning operations are relatively troublesome. The oil fume separation disk 5 can reduce the speed of oil fume dirt adhesion and accumulation on the filter device 8, thereby reducing the frequency of cleaning the filter device 8.

[0031] See also Figure 5 The lower side of the cover body 1 is provided with a plurality of mounting holes 13, each mounting hole 13 is adapted to be provided with a support plate 4, the support plate 4 is detachably fixed on the lower side of the cover body 1 and the support plate 4 fits and covers the mounting hole 13, and the first mounting position 24 is fixed on the upper side of the support plate 4.

[0032] The utility model installs the filter device 8 by fixing the filter device 8 to the first mounting position 24 on each support plate 4 one by one, then inserting the filter device 8 and the support plate 4 upward into the mounting hole 13 as a whole and fixing the support plate 4 on the cover body 1; when removing the filter device 8, the support plate 4 is removed from the cover body 1 and pulled downward to remove the filter device 8 from the cover body 1, so that the filter device 8 can be removed for cleaning and maintenance after being used for a period of time.

[0033] See also Figure 5 , Figure 6 The lower side surface of the cover body 1 and the bottom surface of the cavity 2 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 14 are opened on the rear end of the lower side surface of the cover body 1, and an oil groove 15 is provided at the rear end of the cover body 1. The oil groove 15 is located below the oil leakage hole 14, and the lower end of the oil groove 15 is provided with an oil outlet 16 with a valve connected to the oil groove 15.

[0034] After the filter device 8 in the cover body 1 has been used for a period of time, more oil smoke and dirt will be absorbed by the filter device 8, and the liquid oil will drip downward onto the bottom surface of the cavity 2. Since the lower side surface of the cover body 1 is in an inclined state, the bottom surface of the cavity 2 is also in an inclined state. The oil slides under the action of its own gravity and falls into the oil groove 15 through the oil leakage hole 14 for collection, thereby preventing the oil from accumulating in the cavity 2 and affecting the normal operation of the utility model. After a certain amount of oil is collected in the oil groove 15, the oil in the oil groove 15 is released by opening the valve on the oil outlet 16, thereby facilitating the maintenance of the utility model.

[0035] See also Figure 4 , Figure 6A plurality of baffles 6 are arranged side by side on the lower side of the cover body 1, and the baffles 6 are parallel to the lower side of the cover body 1. The cover body 1 is provided with a first chamber 17 for inserting the front end of the baffle 6 and an L-shaped supporting groove 18 for supporting the rear end of the baffle 6. The supporting groove 18 is located above the oil groove 15, and the air inlet 11 is located on the inner side of the baffle 6.

[0036] When the oil fume separation plate 5 in the above-mentioned air inlet 11 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 15 under the action of their own gravity. The oil droplets thrown onto the baffle 6 by the oil fume separation plate 5 will also slide along the baffle 6 into the oil groove 15, so that the oil droplets are collected by the oil groove 15 to reduce the pollution of the oil droplets to other locations.

[0037] When installing the baffle 6, first insert the front end of the baffle 6 into the first chamber 17 and rotate the rear end of the baffle 6 upward so that the rear end of the baffle 6 moves to the front side of the support groove 18, and then move the baffle 6 backward so that the rear end of the baffle 6 is inserted into the support groove 18. At this time, the front and rear ends of the baffle 6 are respectively supported by the first chamber 17 and the support groove 18, thereby realizing the installation of the baffle 6, which has the advantage of easy installation and is also convenient for removing the baffle 6 from the cover body 1 for cleaning.

[0038] See also Figure 5 , Figure 6 The front end of the cover body 1 is provided with a second chamber 19 for installing the control panel 7. The front end of the second chamber 19 is open and a hinged plate 20 is hinged on the cover body 1. The hinged plate 20 is adapted to cover the front end opening of the second chamber 19.

[0039] A control panel 7 is installed in the second cover plate to supply power to the fan 9 and the oil fume separation plate 5 in the range hood. At the same time, when the filter device 8 is of a type that requires electrical energy (such as high and low voltage electrostatic type and UV photocatalyst catalytic type), the filter device 8 is also powered by the control panel 7. This facilitates the management of various power-consuming units in the utility model through the control panel 7, and the control panel 7 is covered by a hinged plate 20 to prevent oil fume from contaminating the control panel 7 and causing power supply failure. The cover plate is rotated to expose the control panel 4, thereby facilitating subsequent control and maintenance of the control panel 7.
