Description

A kind of air-supply seat of public place

Technical field

The utility model relates to a kind of individual air blow seat, and particularly there are a large amount of individual air blow seats of in a row fixing seats place in a kind of cinema, theater, music hall, meeting room, office, Conference Hall, academic Room etc. of being applicable to.

Background technology

Along with the continuous progress of social fast development and science and technology, people's living standard is in continuous improve, and people are also improving constantly for the requirement of indoor air environment quality and comfort level.The places such as cinema, theater, music hall, meeting room, office, Conference Hall, the academic Room, personnel are intensive, and environment comparatively seals.The air handling system using at present can meet the control requirement of humiture, but resh air requirement and new wind cleanliness factor often do not reach requirement, cause the oxygen concentration in room air on the low side, and gas concentration lwevel is higher, air is relatively dirty, has a strong impact on comfort level and the physical and mental health of human body.Under this background, greatly promote the development of chair type air-supply.

At the cinema, in the large-scale place such as theater, music hall, meeting room, office, Conference Hall, the academic Room, ventilating system can be selected mixed ventilation and replacement aeration conventionally, but two ventilating systems have drawback.For hybrid ventilation, it has not only reduced the quality of the oxygen-enriched air that external device processes obtains, and in the time having personnel to suffer from infectious respiratory disease, personnel's cross-infection also can occur; For displacement ventilation system, it can allow user's health occur sensation uneven in temperature, the problem existing for above-mentioned ventilating system, and someone has proposed the scheme of individual blowing.

But make a general survey of the Patents of published various individual blowings, its designed location of air supply inlet all has path far away with personnel's mouth and nose breathing area.Although compared with the air-supply of large space entirety, can relatively improve near the air quality in personnel seating area, because air supplying distance is longer, through constantly mixing, while waiting until intelligent's body respiratory region, air quality still can be a greater impact.Illustrate for example below.

Be the personalized individual air blow seat of the disclosed one of CN201120554171.0 with regard to application number, on the front surface of its backrest and the upper surface of cushion, be provided with air outlet, the upper surface of two handrails, seat bottom be also provided with air outlet above, whole seat is all air outlet substantially, its air-supply effect, the adjusting of air quantity and air supply direction are difficult for regulating, and approach and even exceed 1m with the breathing area distance of target person.For another example application number is the individualized air supply device of the disclosed a kind of embedded seat armrest of seat of CN201210054080.X, the clearance spaces of armrest side when it utilizes personnel's sitting, individualized air supply device is embedded in chair leg and armrest, air-supply pipeline is realized freely turning down of armrest by multi-stage expansion nesting device, utilize handrail end air outlet to be shipped to human body front side breathing area through the warm pure air of overheated wet process, it can play the effect that prevents coldblast sense and improve body local thermal comfort, but for cinema, theater one is arranged the special seat of the shared handrail of adjacent seat, just there is obvious defect in this utility model, add this air-supply arrangement complex structure, cost is high, for large-scale public place, can not large-scale popularization use.For another example the patent No. is the device of the disclosed a kind of seat air supply of ZL200520134350.3, and the Feng Tong formula mechanism that it utilizes under-seat, is transported to personnel's sitting region by treated air by the wind pushing hole distributing on wind bucket periphery.This seat air supply device is provided with air-valve adjuster in order to regulate the size of air output, thus the wet comfortableness of the heat while improving personnel's sitting.But because the air outlet of device is positioned at seat bottom end regions, this air-supply layout is easily carried to human body respiration district by the dust pollution thing that is positioned at seat bottom, can reduce on the contrary the quality of personnel's air amount.

For the ubiquitous problem of above-mentioned various seat air supplies, necessary research and development one is suitable for these class large-scale public places such as cinema, theater, music hall, and can significantly improve the individual air blow seat of the air quality of user's breathing area.
