Embodiment 1

[0030] A household pyrolysis purifying range hood, such as figure 1 As shown, it includes a pyrolysis oil fume purification device 1, a flue 2 connected to the top of the pyrolysis oil fume purification device 1, and a heat insulation board 3. The flue 2 is provided with a fan 4, and the heat insulation board 3 passes through The fixing assembly is hooked to the bottom of the pyrolysis oil fume purification device 1 .

[0031] The heat shield 3 is hooked to the bottom of the pyrolysis oil fume purification device 1 through a fixing assembly, and the gap formed between the heat insulation board 3 and the pyrolysis oil fume purification device 1 can flow for oil fume, and the fixing assembly can adopt various fixing methods such as common hooks. The heat shield 3 can block the high temperature radiated downward when the pyrolysis oil fume purification device 1 is working, and prevents cooking personnel from being scalded.

[0032] When cooking produces fumes, start the househol...

Embodiment 2

[0034] A household pyrolysis purifying range hood, such as figure 2 and image 3 Shown, different from embodiment 1 is:

[0035] The pyrolysis oil fume purification device 1 includes a decomposition plate 5 and a thermal insulation device 6 arranged outside the side wall of the decomposition plate 5. The interior of the decomposition plate 5 is provided with a cavity, and the upper and lower walls of the decomposition plate 5 are respectively provided with A plurality of through holes 7 arranged in a honeycomb shape, a heating device is provided in the cavity, and the heating device is composed of a plurality of heating pipes 8 connected in parallel, one end of which extends out of the decomposition plate 5 and is connected to a temperature control device. The temperature control device includes a temperature sensor and a temperature controller for detecting the temperature in the cavity, and the temperature controller is connected to the temperature sensor and the heating p...

Embodiment 3

[0037] A household pyrolysis purifying range hood, such as Figure 4As shown, the difference from Embodiment 2 is that the fan 4 is a centrifugal fan, and the range hood also includes a temperature sensor arranged on the heat shield 5 and a temperature alarm device connected to the temperature sensor, The heat preservation device 6 includes a fireproof board 9 and a heat preservation board sequentially from the side close to the decomposition board 5 , and the heat preservation board includes a temperature-insulating vacuum chamber 10 and a thermal insulation material layer 11 sequentially from the side close to the fireproof board 9 .

Abstract

The invention provides a domestic pyrolysis purifying range hood. The domestic pyrolysis purifying range hood comprises a pyrolysis cooking fume purifying device, a flue connected with the top end of the pyrolysis cooking fume purifying device, and a thermal baffle. The flue is provided with a draught fan. The thermal baffle is connected under the pyrolysis cooking fume purifying device in a hanging mode through a fixing assembly. The domestic pyrolysis purifying range hood is simple in structure, convenient and fast to install, practical and convenient to use, reliable in operation, long in working life and high in purifying efficiency. By the adoption of the cooking fume high-temperature combustion and decomposition principle, cooking fumes produced in cooking can be collected to be fully combusted, grease and other toxic substances in the cooking fumes can be effectively removed, and therefore the cooking fumes can be purified completely, emission of harmful gases is avoided, environmental pollution caused by direct emission of the cooking fumes is abated, and the range hood is suitable for purifying and exhausting cooking fumes in home kitchens.

Description

technical field [0001] The invention belongs to the technical field of oil fume purification, and in particular relates to a household pyrolysis purifying range hood and a method for purifying oil fume. Background technique [0002] The range hood is an electrical appliance that discharges the oily fumes produced during the cooking process to the outside, and is now widely used in various families. Compared with foreign cooking methods, Chinese traditional diet tends to use frying, frying, stir-frying and other cooking methods, which are more likely to produce a large amount and high concentration of oil fume. Existing range hoods generally discharge the lampblack directly to the outside through the suction of the fan installed in the range hood. During this process, part of the oil droplets in the range hood will be absorbed or condensed on the air net, components and pipelines of the range hood. , increases the flow resistance of the oil fume, increases the load of the fa...
