Description

Novel vertical blowing-sucking type range hood

Technical Field

The utility model relates to the technical field of range hoods, in particular to a novel vertical blowing and sucking type range hood.

Background

With the development of society and the improvement of living standard of people, people have higher requirements on health and good living environment. Most home-mounted range hoods today have a certain height, approximately 75 cm, between the range hood and the gas cooktop, but the energy capture area of a range hood is typically in the region of about 40 cm below the range hood. Therefore, the general range hood cannot fully suck the oil smoke and other harmful gases to human body generated by cooking and gas combustion, thereby causing certain influence on human health and living environment. In addition, because of incomplete suction of oil smoke and harmful gas and habitual problems of the range hood, a cooker generally closes a kitchen door to prevent contact with other rooms during cooking. In addition to the effects of certain climatic conditions, windows are sometimes closed. Therefore, the mobility of the kitchen air is relatively reduced, and the natural air supplement does not meet the requirements of a kitchen exhaust system, so that the range hood is in an air pumping state, a large amount of unremoved oil smoke further influences the body health, and the wall of the kitchen is polluted. Under the condition of window opening ventilation, as outdoor fresh air is not restrained to a certain degree, the instability of air flow can aggravate the diffusion and overflow of oil smoke.

In order to further improve the effect of the range hood, an outdoor air inlet oil fume removal device is adopted by some people. However, these systems tend to cause diverging outflow of the gas stream, which can result in secondary pollution. There are also patents providing an air curtain diaphragm type gas range, such as the new patent of "wind wall separation type kitchen ventilator" with patent number CN202110422356.4, which utilizes a wind wall pipe installed in the kitchen ventilator casing to blow air downwards, so that a wind wall is formed around the kitchen ventilator to play a separation role. However, the use of the cooking bench has many disadvantages, when in operation, the arms of people and various kitchen utensils influence the effect of the air curtain, so that oil smoke overflows, the vertical air curtain impacts downwards, the oil smoke is not discharged upwards, and oil stains are easily accumulated on the surface of the cooking bench. On the other hand, the confined air current curtain can be to a great extent influence the replenishment of oxygen among the combustion process, and gas combustion degree can descend, can induce a large amount of CO, causes harm to the human body, simultaneously, can influence the requirement to gas among the culinary art process, causes the gas extravagant, increases the daily life cost.
