Description

Multifunctional kitchen air purifier for household use

Technical field

Invention relates to the household kitchen air cleaning facility, specifically, be a kind of situation of polluting according to air in kitchen, to the exhaust gas region scope in the kitchen, drain into the air mass flow in outdoor air mass flow and the inlet chamber, carry out a kind of kitchen air purifying equipment of Comprehensive Control.

Background technology

Existing household kitchen air cleaning facility, a class are hood-shaped shape range hood units.This class range hood, because of the fume exhaust control area, it is the unenclosed construction form, so disadvantage: be that suction gas hood below is to the kitchen range combustion front, in this oil smoke heavily contaminated zone, it is less to form a scope, the exhaust airstream flow field control district of steady air current, simultaneously can't stop the indoor cleaning air that is not contaminated by smoke again, enter this exhaust control area.Consequently, exhaust airstream flow field control regional extent is bigger than normal, and it is bigger than normal to drain into outdoor room air flow.Another kind of is combined type range hood kitchen range frame, as Chinese patent " combined type range hood kitchen range the cabinet " (patent No.: the ZL98225177.7) technical scheme that is proposed, this class household kitchen air cleaning facility, though adopted the technical scheme of closed kitchen range frame and bell-type range hood combination, but building enclosure because of cabinet frame part, it or not a kind of complete gas-tight structure, particularly when the operating surface side is in opening, because this position lacks under any situation, can both effectively cut off contaminated air in the cabinet, and the gas-tight device of convection current between the indoor cleaning air also is used for air balance in the balancing tank, controlled outdoor inlet duct because of lacking one simultaneously; And lack to be specifically designed to and get rid of kitchen range cabinet outside, other air pollution source in the kitchen, the indoor exhaust device of waste gas that is produced or peculiar smell.Thereby existing all kinds of kitchen air purifying equipment, ubiquity can not be according to air pollution situation in the kitchen, selectively control the exhaust gas region scope, in the control exhaust gas region scope, airflow convection between contaminated air and the indoor cleaning air, control is drained into outdoor air mass flow and the air mass flow in the inlet chamber, can be in a kind of controlled poised state.So existing all kinds of household kitchen air cleaning facilities, all need adopt big air quantity, the exhaust running operating mode of high blast, even so, contaminated air in also only can the exclusive segment kitchen, also have simultaneously part indoor cleaning air drained into outdoor, so existing all kinds of kitchen air purifying equipment all can not thoroughly be removed the air pollution in the kitchen.

Summary of the invention

The purpose of this invention is to provide a kind of multifunctional kitchen air purifier for household use, it can control the oil smoke dirt source that kitchen range produce, be completely restricted in a totally-enclosed gas-tight cabinet, and there is gas-tight device to cut off in the totally-enclosed gas-tight cabinet, get convection current between contaminated air and the kitchen indoor cleaning air, with variable air rate air draft blower fan, controlled outdoor inlet duct is combined, make in the totally-enclosed gas-tight frame, the air mass flow of turnover is in a kind of controllable poised state, and controlled indoor exhaust device then is to be used to get rid of beyond the totally-enclosed gas-tight cabinet, other air pollution source in the kitchen, pernicious gas that is produced or peculiar smell.Said system is formed a kind of novel multifunctional household kitchen air purifying device jointly.

Multifunctional kitchen air purifier for household use, adopt following structure: with fire-resistant class plate material, surround a totally-enclosed gas-tight cabinet in the kitchen range outside, the oil smoke dirt source that kitchen range produced, then be completely restricted in this totally-enclosed gas-tight cabinet, like this can be above kitchen range, in the less spatial dimension, form stable exhaust airstream flow field control district; On the operating surface side of totally-enclosed gas-tight cabinet front portion, a controlled gas-tight device of combined type is arranged, include gas-tight window and the air curtain blower fan is formed, effect is to cut off air in the totally-enclosed gas-tight cabinet, and the convection current between the air in the kitchen; Totally-enclosed gas-tight cabinet inside, also be provided with controlled outdoor inlet duct, when being used to solve the exhaust operation, lacking extraneous air in the totally-enclosed gas-tight cabinet replenishes, the air draft blower fan that is caused, the intake negative-pressure windage is excessive, the problem of suction and discharge weak effect, thereby can keep the air balance in the cabinet, be in a kind of poised state all the time.Totally-enclosed gas-tight portion cashier's office in a shop is the suction bellows of a bell-type shape, is furnished with at this box house: variable air rate air draft blower fan, oil smoke separator-filter, connection airduct, controller, illuminating lamp; Variable air rate air draft blower fan also can adopt the version that is installed in suction bellows outside.On the suction bellows casing, also be provided with the indoor exhaust device of controllable one or more positions.Above-mentioned part is common forms a comprehensive kitchen air purifying system, and this system can provide multiple operation mode according to air pollution situation in the kitchen, for its selection.

Owing to adopt technique scheme, this invention multifunctional kitchen air purifier for household use, can be according to air pollution situation in the kitchen, to the exhaust gas region scope in the kitchen, drain into outdoor air mass flow, with the air mass flow in the inlet chamber, carry out a kind of multifunctional household kitchen air purifying system of Comprehensive Control.Compare with prior art, this multifunctional kitchen air purifier for household use can be according to the air pollution situation in the kitchen, select the optimum operation scheme, with the operating mode that the most reasonably turns round, thoroughly remove the various air pollutions in the kitchen, and advantage efficient, energy-conservation, low noise is arranged.
