Description
Technical field
The invention belongs to range hood technical fields, specially refrigeration-type range hood.
Background technique
With the improvement of living standards, living circumstance is greatly improved, range hood is as must in kitchen
Indispensable household electrical appliance effectively reduce the harm of oil smoke diffusion couple human body generation.However traditional range hood is still
The Shortcomings in structure and theory, exclusion oil smoke efficiency is to be improved, especially when oil smoke yield is larger, it is difficult in time
Drain into outdoor, in environment in health have it is many unfavorable；During the broiling summer, stove fire high temperature when culinary art and on the hot gas risen
Stream greatly affected the thermal comfort of human body, and kitchen is due to the features such as its oil smoke is big, area is small, often with it is amorphous from
So based on ventilation, not within the scope of air conditioning area, lead to the today being continuously improved in quality of the life, the culinary art in kitchen still needs
Higher environment temperature is endured, especially in places such as hotel, dining rooms, it is desirable that cook works long hours, simple kitchen ventilation
It is very universal to be difficult to the phenomenon that meeting comfort requirement, mutually disconnecting with modern life theme in this way.
Traditional range hood will be produced by forming negative pressure above kitchen range in the waste and cooking process of cooking stove burning
The raw oil smoke being harmful to the human body is taken away rapidly, and discharge is outdoor, reduces pollution, purifies air.It but is only that a smoke evacuation is explosion-proof
Household electrical appliance, do not have any processing to kitchen thermal comfort；When oil smoke is splash, room cannot be drained into time by having many oil smoke
Outside, it polluted indoor environment, the simple air quantity that improves can greatly increase kitchen noise, it is difficult to endure.
Currently, there are also air curtain formula kitchen ventilators, on the basis of traditional kitchen ventilator, increase scrak type air curtain, with smoke evacuation
Cooperating, main purpose are to reduce overflowing for oil smoke by above sending/descending air-supply one of air curtain of formation and dissipate, to guarantee kitchen sky
Gas quality.The effect of good shielding oil smoke is played using air curtain, but does not consider the comfortableness problem in kitchen equally, only
It is further on conventional angle.
In addition there are also kitchen special air conditioners, i.e., install additional on the basis of common air-conditioning quick detachable, easy cleaning grease proofing together
Dirty strainer, refrigeration and circulation theory are identical as common air-conditioning.Its market price is differed at 3000~8000 yuan, acquisition cost compared with
It is high, it is difficult to universal.In addition embedded type air conditioner is not suitable for all family kitchens (such as: layer height does not allow), and console mode can account for again
It is inconvenient with kitchen originally narrow space；
Especially cooking area is the high-temperature region in kitchen, is the emphasis of thermal comfort control, uses the entire kitchen of airconditioning control
Temperature rather some waste energy；If the air current composition of air-conditioning is dealt with improperly, the basic function for excluding oil smoke can be generated larger
It influences, as a result puts the cart before the horse.
Summary of the invention
The purpose of the present invention is to provide a kind of refrigeration-type range hoods, overcome the shortcomings of existing smoke exhaust, design one
Cold wind air curtain formula kitchen ventilator of the kind based on semiconductor refrigerating guarantees that the Studies of Human Body Heat in summer culinary cuisine area relaxes by cold wind air curtain
Adaptive improves smoke exhaust efficiency to large extent, reduces the diffusion of oil smoke, while reducing the occupancy and throwing to space as far as possible
The cost of money.
The specific technical proposal is:
Refrigeration-type range hood, including range hood main body, range hood main body are equipped with smoke outlet, smoke duct；
Cross flow blower is additionally provided on front side of the range hood main body, the air outlet of cross flow fan and the item of lower section stitch
The connection of type air outlet；Scrak type air outlet is located on front side of smoke outlet；
It is additionally provided with cold wind air duct and heat dissipation wind channel on the outside of the smoke duct of range hood main body, heat dissipation wind channel is located at cold wind wind
Have between road and smoke duct, between heat dissipation wind channel and smoke duct through orifice, heat dissipation wind channel top offers heat dissipation
Air inlet of air duct；
Semiconductor refrigerating heap is embedded between cold wind air duct and heat dissipation wind channel, and semiconductor refrigerating heap is to the gas in cold wind air duct
Cooling, heat dissipation wind channel radiates to semiconductor refrigerating heap；Heat-barrier material is equipped between cold wind air duct and heat dissipation wind channel；Cold wind air duct top
Portion is cold air duct air inlet, for sucking room air；Air outlet is connect with cross flow blower below cold wind air duct；
Condensate drain pan inclination is placed in below refrigeration heap cold end；
Cross flow blower is connected to power supply with semiconductor refrigerating heap.
It further, further include external temperature sensor, the temperature sensor is mounted in range hood main body,
For monitoring cooking area temperature.
It further, further include infrared human body sensor, whether the operating space for monitoring range hood main body has personnel
It stops, infrared human body sensor is connect with cross flow blower, controls cross flow blower start and stop.
Semiconductor refrigerating chip technology comparative maturity, has the characteristics that refrigerating capacity is small, efficiency is lower, makes it difficult to answer
In the air conditioning of the big scale of construction, if but be mounted in kitchen ventilator and freeze for regional area, reaction speed is fast, volume
The advantages of small, low noise, just highlights, and " semiconductor refrigerating heap " is enough to eliminate the refrigeration duty of regional area.Therefore one kind is designed
Cold wind air curtain formula kitchen ventilator based on semiconductor refrigerating, and it is aided with reasonable automatic control, cooking fume can either be reduced and existed
Indoor diffusion also meets the comfort requirement of kitchen personnel.
The present invention is had the benefit that compared with prior art through the downward air jet formation in smoke exhaust front end
Human comfort can be improved in annular cold air curtain, and simultaneously effective isolating oil soot is to external diffusion, due to only controlling regional area
Temperature, then be aided with reasonable control strategy and can reduce energy consumption as much as possible.It has to indoor environmental pollution it is small, be conducive to
Human health, clean energy, noise are small, the advantages that taking up little area, and main structure is simple, and design concept is ingenious, wide market.
