Abstract
A jet fume extractor is characterized in that the place between a fume cover and a diffuser is equipped with a steam and fume mixing chamber, which is connected and communicated with the extractor. The steam and fume mixing chamber is also equipped with a steam collecting hood, which is connected and communicated with the extractor. A steam inlet and a steam outlet of a cartridge heater are connected. The periphery of the cartridge heater is equipped with a heat collecting plate and a heat-insulating layer. After water is heated and becomes steam through the cartridge heater, it enters the steam collecting hood. It passes through a Laval nozzle in the steam and fume mixing chamber and forms steam injection to carry away the oil fume form the fume cover. The oil fume extracting purposes is obtained. The jet fume extractor does not waste power and does not mechanically rotate; the structure is simple and easy in use, and suitable to families.
Description
The utility model relates to a kind of injection range hood, belongs to cleaning tool, returns the A47L/04 class.
Before the utility model, home-use range hood all is electronic exhausting formula, and characteristics are that draft is strong, the oil smoke of family kitchen can be extracted out, but complex structure, volume is big, consumed power, and when using, oil smoke steam is met when air-cooled and is frozen into liquid, in range hood, accumulate in a large number, and partly oil smoke liquid leaks from the side, influences dietetic hygiene.
The purpose of this utility model is to provide a kind of waste heat that utilizes, and does not have the family expenses injection range hood that mechanical driving component does not consume energy again.Utilize this novel injection range hood, the injected jet rows that water vapor produced of oil smoke steam is removed outdoor, and oil smoke steam can not stockpile in machine and leaks because of freezing into liquid.
The technical solution of the utility model is such: arrange to be aided with thermal-arrest plate and thermal insulation layer again by a spiral heating tube (as copper tube) around it in the thermal-arrest vaporizer, install inlet valve at the two ends of heating pipe and go out steam valve.The vapour of remittance cover, the mixed cavity of vapour cigarette, Diffuser are arranged in steam jet ejector, and smoke absorbing hood is contained in the bottom of steam jet ejector.Laval type nozzle is housed in vapour cigarette mixing chamber simultaneously.After steam comes out from the steam (vapor) outlet in the thermal-arrest vaporizer, enter in the remittance vapour cover, form steam jet by the Laval type nozzle in the vapour cigarette mixing chamber then and enter in the Diffuser through connecting tube.Owing to form jet-like behind the steam process Laval type nozzle, the oil smoke in the smoke absorbing hood is taken away, reach lampblack-pumped purpose.
The utility model is compared with background technique, utilizes waste heat, consumed power not, and simple in structure, cleaning is convenient, and use value is arranged.
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
Fig. 1 is the combination cross-sectional schematic of steam jet ejector of the present utility model and smoke absorbing hood, also is the specification digest accompanying drawing.
Fig. 2 is the sectional structure schematic representation of thermal-arrest vaporizer of the present utility model.
During enforcement, according to shown in Figure 2 making, wherein heating pipe 7 is done spirality with the thermal-arrest vaporizer in elder generation, and is outer with 8 protections of thermal-arrest plate, uses thermal insulation layer 9 insulations, heat insulation again.During use, earlier the thermal-arrest vaporizer is placed on town gas or the liquid gas cooking stove, opens coal gas or liquid gas, from water intake 10 water inlets.Utilize the heat of coal gas or coalification gas firing that the water in the heating pipe 7 is heated until becoming steam, discharge from steam (vapor) outlet 11.The steam of discharging is sent into the steam inlet 1 of steam jet ejector through connecting tube (not marking on the figure), and sends into Diffuser 5 by converging the Laval type nozzle 4 that vapour cover 2 enters vapour cigarette mixing chamber 3.Because uperize stream forms a negative pressuren zone through Laval type nozzle 4 backs in vapour cigarette mixing chamber 3 and smoke absorbing hood 6 connecting parts, therefore the soot gas in the smoke absorbing hood 6 can be taken out of outdoorly via Diffuser 5, reach lampblack-pumped purpose.
The profile of vapour cigarette mixing chamber 3 can be a cylinder, also can be the cubic bodily form, and Laval type nozzle 4 wherein is arranged in the vapour cigarette mixing chamber 3.
The most preferred embodiment of this case is: the profile of remittance vapour cover 2 is semicircle, and the profile of vapour cigarette mixing chamber 3 is the cylinder bodily form, and the profile of Diffuser 5 also is the cylinder bodily form.It is rectangular tubaeform that the lower end of smoke absorbing hood 6 is.
Claims (3)
1, a kind of injection range hood, it comprises smoke absorbing hood (6), it is characterized in that smoke absorbing hood (6) upper end links to each other with the bottom of vapour cigarette mixing chamber (3) and communicates, the both sides of vapour cigarette mixing chamber (3) link to each other with an end of remittance vapour cover (2) and Diffuser (5) respectively and communicate, on the remittance vapour cover (2) steam inlet (1) is arranged, this steam inlet (1) links to each other with the steam (vapor) outlet (1) of heating pipe (7), outer periphery at heating pipe (7) is equipped with thermal-arrest plate (8) and thermal insulation layer (9), and the water intake (10) of heating pipe (7) and steam (vapor) outlet (11) are positioned at outside thermal-arrest plate (8) and the thermal insulation layer (9).
2, injection range hood according to claim 1 is characterized in that being arranged with in the vapour cigarette mixing chamber (3) Laval type nozzle (4).
3, injection range hood according to claim 1, it is characterized in that heating pipe (7) in the shape of a spiral shape be arranged in the thermal-arrest vaporizer.
