Description
Technical field
The present invention relates to a kind of device of air that changes gear that is suitable for the kitchen, rural area.
Background technology
Oil smoke is invaded respiratory tract, can cause symptoms such as anorexia, vexed, lassitude, drowsiness, fatigue and weak, medically is called " oil smoke syndrome ".Oil smoke main component methacrylaldehyde has strong impulse to eye, nose, throat mucous membrane, can cause diseases such as chronic keratitis, rhinitis, sphagitis, tracheitis.Fat oxidation thing in the oil smoke can cause cardiovascular, cranial vascular disease.Oil smoke makes the elderly more be prone to suffer from cardiovascular and cerebrovascular disease.Contain a kind of carcinogenic substance that is called as BaP in the kitchen fume, BaP can cause the chromosomal damage of human body cell, and long-term suction can be brought out the lungs tissue canceration.The 40-60 of long-term contact oil smoke year women, the danger of suffering from lung cancer, breast cancer increases 2-3 doubly.
Cholorination is the disinfection technology that China continues to use for many years and still in giving water treatment, generally adopts.But over nearly 20 years, people find gradually, cholorination the time, some organicly reacts with inorganic constituents in chlorine and the water, generates a series of halo organic by-products, wherein most of health is constituted potential harm.
If water does not reach boiling point, the chlorine element can't evaporate in the air, and human body is safe from harm.If but with boiling tap water, and continue to boil a period of time, chemical change will take place in the chlorine element in the running water; Become the chemicals of a kind of crying " haloform "; Evaporate in the air in kitchen, get into human body through breathing, getting off for a long time to influence health.The vapourizing temperature of haloform is lower than water, and when heating, haloform all can be evaporated in the air earlier than steam, and evaporation capacity also can be more than steam.Haloform is sucked by human body with air, can cause kidney and carcinoma of urinary bladder, also can cause premature labor in pregnant women, miscarries or give birth to monster.
Traditional kitchen, rural area is mostly rather spacious; Generally all use or keep to make the land used pot and stove, use timber, branch, stalk, straw etc. to act as a fuel, even if economic relatively advanced area; When using coal gas, coal stove and electric power kitchen range, still keep traditional ground pot and stove.
The most floor height in kitchen, rural area is higher, and furred ceiling and smoke exhaust ventilator seldom are installed.One of drawback of ground pot and stove, the cigarette ash that in use produces is many, all can produce certain harm to respiratory system and vision system; Two of drawback, the relative aperture of ground pot and stove is bigger, and the steam that therefore produces is also a lot.In today that the life of farmers level promotes day by day, improve the kitchen condition and become a problem demanding prompt solution.Common lampblack absorber can only act on the below kitchen range top of fixed position, and efficient is limited, is mainly used in the kitchen, city, and on the other hand, the relative people in the countryside of lampblack absorber price are higher.These characteristics of kitchen, rural area and ground pot and stove make most Chinese countryside kitchens all not substitute device of air, and the work of daily kitchen all is in a kind of in the bigger adverse circumstances of human harm.
Summary of the invention
The present invention is directed to kitchen, present rural area seldom install furred ceiling and smoke exhaust ventilator, the big problem of pot and stove oil smoke; Proposed a kind of be applicable to the rural area conventional kitchen substitute device of air, simple in structure, practical, and can suit measures to local conditions, be applicable to the device of air that changes gear in most traditional kitchens, rural area.
The device of air that changes gear that is suitable for the kitchen, rural area of the present invention; It is characterized in that: comprise channel of gas collection, ventilation fan; Described channel of gas collection comprises furred ceiling, sloping baffle; The front side edge of described furred ceiling and the top edge of described sloping baffle are fixed, and the common channel of gas collection that forms of first wall that contacts with back side edge, and an end of described channel of gas collection extends on second wall; Described ventilation fan be installed in second wall on, and through being installed in the ventilation fan switch control on described second wall.
Described furred ceiling is a flat-top.
The width of the furred ceiling of described channel of gas collection is less than the lower limb of the described sloping baffle distance to first wall.
The angle of described sloping baffle and horizontal plane is between 45 °～75 °.
The length of described channel of gas collection is put length adjustment according to the kitchen range that are positioned at the channel of gas collection below.
Described sloping baffle is adjusted according to the kitchen range size to the distance of first wall.
The material of described gas collecting apparatus adopts light material.
The material of described gas collecting apparatus adopts three-ply board, aluminium alloy or solid fiberboard.
During use, earlier with the ventilation fan switch opens, the control ventilation fan is started working; Because channel of gas collection is very long, the oil smoke and the steam that therefore are in all cookers generations under this channel of gas collection all can converge in the channel of gas collection of top, and ventilation fan is started working; Air in the channel of gas collection is taken away; Produce certain negative pressure, make channel of gas collection form a negative pressuren zone, force the outer air of passage to flow into channel of gas collection rapidly; As long as the kitchen has window and outdoor ventilation, will constantly have fresh air to get into the kitchen, and the waste gas in kitchen is extracted the kitchen just through channel of gas collection out by exhaust fan; Kitchen operation finishes, and closes exhaust fan.
The invention has the beneficial effects as follows: (1) this device size, size flexibility and changeability, can suit measures to local conditions; (2) this device uses low-cost regular tap and exhaust fan, and general rural households can both afford; (3) material of this device also is easy to get very much, can adopt aluminium alloy, mopping three-ply board, even the cardboard of hard, can accomplish twice laid, economizes on resources.
