Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to a smokeless range hood. Background Art

[0002] There is a type of all-in-one fume purifier on the market, which is usually composed of a fan, a filter, an electronic controller, etc. When we cook in the kitchen, the all-in-one fume purifier can filter out the fume and odor to make the indoor air fresher. Since this type of all-in-one machine does not need to install a smoke exhaust pipe and does not emit fume to the outside, it is widely used in the catering industry.

[0003] However, at present, this type of oil fume purification integrated machine usually sends the oil fume directly upward into a chamber where a filter is installed, and arranges fans on the left and right sides of the chamber so that the oil fume flows unidirectionally in the chamber and is discharged from the chamber through the air outlet. Since the oil fume near the air outlet is only discharged from the chamber after passing through a part of the filter near the air outlet, there is incomplete filtration, which reduces the purification effect of the range hood.

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-Figure 5 The smokeless duct range hood of this embodiment includes a cover body 1, a shell body 2 and a control panel 3. The cover body 1 and the shell body 2 are both hollow structures. Openings are provided at the upper and lower ends of the cover body 1. A plurality of oil fume separation disks 4 are provided in the lower opening 12 of the cover body 1. A smoke removal mechanism 5 is provided in the cavity of the shell body 2. An air inlet 21 and an air outlet 22 are provided on the shell body 2. The air inlet 21 is communicated with the upper opening 11 of the cover body 1. The air inlet 21 and the air outlet 22 are respectively located on both sides of the smoke removal mechanism 5. The control panel 3 is arranged on the shell body 2 and is electrically connected to the smoke removal mechanism 5 and the oil fume separation disk 4. A fan 6 for exhausting air to the outside of the shell body 2 is provided in the shell body 2.

[0022] The utility model is installed above the oil fume area. When in use, negative pressure is formed in the cavities of the shell body 2 and the cover body 1 by starting the fan 6, so that the oil fume below the cover body 1 is sucked into the cavity of the cover body 1 through the oil fume separation plate 4 in the lower opening 12 of the cover body 1. The oil fume separation plate 4 can intercept the oil fume particles passing through it when it rotates at a high speed. The oil fume gas after passing through the oil fume separation plate 4 continues to move through the air inlet 21 of the shell body 2 into the cavity of the shell body 2 and moves to the air outlet 22. Since the air inlet 21 and the air outlet 22 are located on both sides of the smoke removal mechanism 5, it is ensured that the air mixed with oil fume gas moves from one side of the smoke removal mechanism 5 to the other side, thereby ensuring that the oil fume gas therein can be fully purified in the smoke removal mechanism 5, thereby improving the oil fume purification effect of the utility model.

[0023] See also Figure 1-Figure 4 The lower end of the shell 2 is adapted to fit and fix into the upper opening 11 of the cover body 1 , the air inlet 21 is arranged on the left side of the lower end surface of the shell 2 , and the air outlet 22 is arranged on the right side of the front end surface of the shell 2 .

[0024] A fixed connection between the cover body 1 and the shell 2 is achieved by connecting and fixing the lower end of the shell 2 to the upper opening 11 of the cover body 1 (for example, plugging or further reinforcing by welding, screws, etc.), so that the cover body 1 and the shell 2 can be transported separately to the site for assembly and installation. At the same time, the bottom of the shell 2 seals the upper opening 11 of the cover body 1 to prevent oil fume gas from leaking from the upper opening 11 of the cover body 1.

[0025] See also Figure 2-Figure 3 The oil fume separation trays 4 are provided with three and are arranged in the lower opening 12 of the cover body 1 at equal intervals on the left and right. A driving motor 41 is provided on the inner side of the oil fume separation trays 4, and the driving motor 41 is electrically connected to the control panel 3.

[0026] Since the oil fume enters the cavity of the cover body 1 and the shell 2 through the oil fume separation plate 4, the amount of oil fume sucked in per unit time can be increased by setting up multiple oil fume separation plates 4, while ensuring that the oil fume generated on the left and right sides below the cover body 1 can be sucked in by the adjacent oil fume separation plates 4, thereby reducing the amount of oil fume diffused into the room.

[0027] See also Figure 1 , Figure 5 The fan 6 is arranged in the air outlet 22, and a hanging plate 24 is detachably fixed on the front end surface of the shell 2, and the hanging plate 24 is fixed to the shell 2 by hand screws 25. The air outlet 22 is opened on the hanging plate 24, and the air outlet end 61 of the fan 6 is fixed on the hanging plate 24 and the air outlet end corresponds to the position of the air outlet 22. The base 62 of the fan 6 is fixed on the shell 2.

[0028] In this embodiment, the fan 6 adopts a turbine fan 6, which has the advantage of a large air volume, thereby accelerating the suction of oil smoke and improving the purification rate of oil smoke. The fan 6 is arranged in the air outlet 22 to reduce the probability of direct contact between the fan 6 and the oil smoke, thereby reducing the rate at which the fan 6 is contaminated by the oil smoke and reducing the cleaning frequency of the fan 6.

[0029] The hanging plate 24 is detachably fixed to the housing 2 by means of hand screws 25, so that the user can install the fan 6 and remove the hanging plate 24 to disassemble, clean or repair the fan 6.

[0030] See also Figure 5 The smoke removal mechanism 5 includes a plurality of high and low voltage electrostatic fields 51 arranged side by side.

[0031] When the oil fume gas enters the high and low voltage electrostatic field 51, the oil fume gas is ionized under the action of the high voltage electric field, and most of it is degraded and carbonized; a small number of tiny oil particles that are not intercepted by the oil fume separation disk 4 move to the positive and negative plates of the electric field under the action of the electric field force of the adsorption electric field and the airflow, are collected on the plates and flow under the action of their own gravity, and the remaining micron-level oil mist is degraded into carbon dioxide and water by the electric field, and finally discharged into clean air; at the same time, under the action of the high voltage generator, the harmful gas in the oil fume gas can be decomposed by the ozone generated in the electric field, remove the odor, and the harmful gas is also removed. Because it is easy to capture dust with a smaller particle size, the purification effect is higher. By purifying the oil fume gas by passing it through multiple high and low voltage electrostatic fields 51 in sequence, the purification rate of the oil fume gas is improved, and the cleanliness of the indoor air is guaranteed.

[0032] See also Figure 5 The front end of the shell 2 is provided with a through hole 23 that is adapted to the size of the smoke removal mechanism 5. The high and low voltage electrostatic field 51 is inserted through the through hole 23 and fixed in the cavity of the shell 2. The control panel 3 is adapted to cover and be fixed on the through hole 23. The control panel 3 is hingedly connected to the shell 2.

[0033] When installing and cleaning the high and low voltage electrostatic field 51, the through hole 23 can be exposed by rotating the control panel 3, so that the staff can directly insert the high and low voltage electrostatic field 51 into the cavity of the shell 2 through the through hole 23 in sequence, and pull the high and low voltage electrostatic field 51 out of the shell 2 through the through hole 23. Therefore, it has the advantage of easy installation and disassembly and cleaning. After the installation is completed, the control panel 3 is rotated to cover the through hole 23 again and fixed, reducing the risk of oil fume gas leakage from the through hole 23 during use.

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.
