Problems solved by technology

[0004] The device in the above-mentioned patent is equipped with an ozone generator, and uses the ozone generator to generate ozone to sterilize and purify the inside of the range hood. However, the ozone generator has been in the fume environment inside the range hood for a long time, and the adhesion of a large amount of oil or dust will make the ozone The circuit of the generator is short-circuited and the ozone generator is damaged, thus affecting its sterilization and purification effect
Furthermore, the specific gravity of ozone molecules is greater than that of air, so the ozone generated by the ozone generator will not automatically disperse, resulting in uneven ozone concentration inside the range hood, that is, the concentration of ozone near the ozone generator is higher, while the concentration of ozone far away from the ozone generator The concentration of ozone is low, and the molecules of ozone are extremely unstable and easy to decompose, which further exacerbates the uneven concentration of ozone inside the range hood, and the effective sterilization and deodorization of ozone requires a certain concentration and a certain period of time.
It can be seen that the structure of the existing range hood with an ozone generator has limited the full play of the sterilization and deodorization function of ozone, and needs further improvement

Embodiment 1

[0029] Such as Figure 1-7 As shown, a range hood includes a casing 21 with an inner cavity 210 and an air outlet cover 211, the inner cavity 210 is provided with a fan 22, the above air outlet cover 211 is provided with an air outlet cavity 23, and the outlet The air chamber 23 is located above the inner chamber 210 and communicates with the inner chamber 210 through the air inlet 231. The top of the air outlet chamber 23 has an air outlet 232, and the air outlet 232 is provided with an air outlet valve plate capable of opening and closing the air outlet 232. 271.

[0030] Further, the air outlet hood 211 is also provided with a clean chamber 24 and a mixing chamber 25 , the clean chamber 24 is provided with an ozone generator 26 , and the mixing chamber 25 is provided with a mixer 202 . Above-mentioned purification chamber 24 and mixing chamber 25 are communicated by gas outlet 242, and the ozone produced by ozone generator 26 is introduced into mixing chamber 25 through th...

Embodiment 2

[0039] Such as Figure 8-10 As shown, the difference from Embodiment 1 is that in this embodiment, the above-mentioned air duct 28 is provided with a filter unit 280 inside the air duct 28 for filtering oil fume, and the filter unit 280 can filter the oil fume molecules in the air flow, thereby Avoid the soot molecules from polluting and damaging the ozone generator 26 . The filter unit 280 traverses in the air duct 28 and is arranged at intervals along the length direction of the air duct 28. Each filter unit 280 includes at least two filter bodies arranged at intervals along the width direction of the air duct 28. At least one end of each filter body is connected to the air duct 28. The inner wall of the air pipe 28 is fixed, and a filter channel 2800 for air flow is formed between adjacent filter bodies. Such a design can make the fume molecules entering the air duct 28 collide with the filter unit 280 smoothly, thereby better filtering the fume molecules. Further, the fi...

Abstract

The invention relates to an extractor hood. The extractor hood comprises a casing having an inner cavity, an air outlet chamber and an ozone generator. A fan is arranged in the inner cavity. The air outlet chamber is provided with an air outlet and an air inlet and is communicated with the inner cavity through the air inlet. An air outlet valve plate for closing and opening the air outlet is arranged in the air outlet. The extractor hood also comprises a purification chamber. The ozone generator is arranged in the purification chamber. The purification chamber is provided with a gas outlet. Ozone produced by the ozone generator is fed into the inner cavity through the gas outlet. The purification chamber is communicated with the air outlet chamber through an air duct. Air flows in the fanare fed into the purification chamber through the air duct so that the ozone gas is disturbed and premixed, the ozone gas is driven to enter the inner cavity through the gas outlet and then enter theinner cavity of the fan, and the ozone gas is introduced into the air outlet chamber through rotation of the fan and thus the circulation inside the extractor hood is formed and the dynamic equilibrium state and the uniformity of the concentration of ozone needing to be treated in the extractor hood are realized.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with sterilization and purification functions. Background technique [0002] The range hood is used to discharge the flue gas outside. After a period of use, the inside of the range hood tends to accumulate oil, such as the smoke collection hood and fan of the range hood. The long-term accumulation of oil stains will easily lead to the breeding of bacteria inside the range hood, and lead to the generation of peculiar smell, which will affect the kitchen environment and the health of users. [0003] Traditional range hoods generally do not have the function of sterilization and purification. Ozone is a gas with strong bactericidal ability, and its bactericidal ability is about 3000 times that of chlorine gas. The Chinese invention patent that the application number is 201110258991.X (the application publication number is CN 102966987 A) discloses a kind of smoke suction an...
