Embodiment 1

[0035] Such as Figure 1-12As 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 an air inlet (not shown, which is a conventional structure of a range hood), and the top of the air outlet chamber 23 has an air outlet 232, and the air outlet 232 An air outlet valve plate (not shown, which is a conventional structure of a range hood) capable of opening and closing the air outlet 232 is provided. In this embodiment, the above-mentioned air outlet cover 211 is also provided with a purification chamber 24 and a heating chamber 25. The above-mentioned air outlet chamber 23, purification chamber 24 and heating chamber 25 are all arranged above the inner chamber 210, and the three are arranged side b...

Embodiment 2

[0044] Such as Figures 13 to 14 As shown, different from Embodiment 1, the heating device 26 in this embodiment includes three heating plates 261, and each heating plate 261 is arranged in the heating chamber 25 at intervals along the airflow direction, and the heating plate 261 between adjacent heating plates 261 The gap forms the gas channel 260 so that the gas flow entering the heating chamber 25 can be heated more effectively.

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 purification chamber and a heating chamber arearranged in the casing. The ozone generator is arranged in the purification chamber. The purification chamber is communicated with the inner cavity through a first air outlet. The first air outlet isprovided with a first air outlet valve plate for opening and closing the first air outlet. A heater for heating gas is arranged in the heating chamber. The heating chamber is communicated with the inner cavity. The purification chamber is communicated with the heating chamber through a vent hole. The vent hole is provided with a valve for opening and closing the vent hole. The ozone produced by the ozone generator is fed into the heating chamber through the vent hole. Compared with the existing extractor hood, the extractor hood can effectively prevent the ozone generator from being damaged by the oil smoke pollution, can efficiently decompose the ozone, can prevent the ozone efflux from affecting the air and the human health, can dry the inner part through heated hot gas and can effectively prevent the breeding of bacteria.

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...
