Description

Technical Field

[0001] The present invention relates to the technical field of kitchen purification equipment, and more specifically to a composite oil fume purification all-in-one machine. Background Art

[0002] A range hood is a kitchen appliance installed above the kitchen stove to purify the kitchen environment. It can quickly extract the fumes that are harmful to the human body generated during the cooking process and discharge them outdoors, so as to reduce indoor pollution and purify indoor air.

[0003] Currently, commonly used range hoods include electrostatic fume purifiers that use the principle of static electricity to purify oil fumes, or UV purifiers that use UV ultraviolet light beams to decompose oil fume gases; however, the modules used to generate static electricity or the modules that generate UV light beams in these range hoods and the ventilation ducts in the range hoods are prone to adhesion of oil stains. After long-term operation, the large amount of residual oil stains will seriously affect the working performance of the range hood and reduce the purification efficiency, so improvements are needed. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a composite oil fume purification all-in-one machine, which can.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A composite oil fume purification all-in-one machine, characterized in that it comprises an oil fume hood body, wherein the oil fume hood body is provided with an oil-gas separator, a mechanical purifier, an electrostatic purifier, a photolysis purifier, an exhaust fan, a condensation purifier and an activated carbon purification mechanism which are connected in sequence. Under the negative pressure of the exhaust fan, the oil fume enters from the air inlet of the oil fume hood body, passes through the curved channel of the oil-gas separator for preliminary interception of large oil fume particles, and then passes to the mechanical purifier to use its mechanical impeller for centrifugal separation of oil and gas, and then passes through the electrostatic purifier for high-voltage electric field separation of the oil fume, and then passes through the photolysis purifier for photolysis and deodorization, and then the smoke is transported to the condensation purifier by the exhaust fan for condensation and deodorization, and finally passes through the activated carbon purification mechanism at the end for further deodorization.

[0007] Furthermore, the oil-gas separation device includes an L-shaped buffer plate, a partition is provided on the inner side of the buffer plate, and a plurality of rows of corrugated plates are provided on the partition. A curved channel is formed between any two adjacent corrugated plates, and each of the curved channels is connected to the buffer channel between the buffer plate and the partition. A through opening is provided at the lower end of the buffer plate to discharge the gas in the buffer channel to the mechanical purifier.

[0008] Furthermore, the mechanical purifier adopts a high-speed rotating impeller of 1300 revolutions per minute.

[0009] Furthermore, a pre-filtering and air-balancing net is also provided at the front end of the electrostatic purifier.

[0010] Furthermore, the electrostatic purifier and the photolysis purifier are both detachably mounted on the range hood in a drawer-like manner.

[0011] Furthermore, the condensing purification device includes an air inlet pipe, a condensing box and an air outlet pipe. The air inlet pipe is sealed and connected to the air outlet pipe through a plurality of ventilation cooling pipes. Each of the ventilation cooling pipes is located in the condensing box. Cold air is generated in the condensing box to cool the ventilation cooling pipes, so that the flue gas is liquefied and condensed on the belly wall of the pipe.

[0012] Furthermore, the activated carbon purification mechanism uses honeycomb activated carbon, and the honeycomb activated carbon is installed at the air outlet of the condensation purification device.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. Through the oil-gas separator, mechanical purifier, electrostatic purifier, photolysis purifier, exhaust fan, condensation purifier and activated carbon purification mechanism connected in sequence, the multi-effect purification of oil fume is realized. The oil-gas separator and mechanical purifier at the front end can intercept the oil fume to a great extent at the physical level, greatly reducing the load of the subsequent part of the oil fume, and then the electrostatic purifier and photolysis purifier are used to decompose, separate, purify and deodorize the oil fume in a more detailed manner, greatly improving the purification efficiency. The setting of condensation purifier and activated carbon purification mechanism can separate and deodorize the tail flue gas once, and further improve the purification efficiency. The purified gas of the device can be discharged in the kitchen. With the kitchen fresh air system, it is actually verified that the purification efficiency is much higher than that of the same oil fume purifier on the market. BRIEF DESCRIPTION OF THE DRAWINGS
