CN2230421Y - Fume-exhausting hood for gas water-heating device - Google Patents

Abstract

The utility model relates to a fume-exhausting hood for a gas water-heating device in the household. The configuration is a cone shape. The lower port of the utility model is a rectangular port with the dimension larger than the upper end dimension of the gas water-heater device. The upper end is a circular short pipe for connecting with a smoke flue. The hot exhaust gas produced by the gas water-heater device is automatically discharged out of the room. The utility model is favorable to the health and safety of the gas water-heater device users.

Description

The gas heater enclosure

The utility model is a kind of device that discharges burnt gas of installing above about the gas heater that general family uses.

Gas heater utilizes imflammable gas such as coal gas or day hot gas to carry out work, can produce large quantity of exhaust gas thus, comprising that pernicious gases such as carbon dioxide gas and carbon monoxide gas and titanium dioxide nitrogen all are emitted on indoorly causes certain infringement to the people, necessity of room ventilation when so product description emphasizes to use the hot device of combustion gas, but objective analysis, a large amount of pernicious gases result from indoor being discharged into again fails to make the people to break away from and the contacting of waste gas in the outdoor process.In addition, the contradiction that indoor ventilation and winter, the heating of house insulation produced still has to be solved.

Task of the present utility model provides a kind of large quantity of exhaust gas that produces can be effectively with gas water heater working the time and directly is discharged into outdoor easy device rapidly.

The utility model is achieved in that the enclosure of settling a bullet at the position of the upper end of gas heater discharging waste gas, links at the upper port of cover and chimney and leads in the floss hole of open air or corridor, and it is outdoor that large quantity of exhaust gas directly is discharged to.

Characteristics of the present utility model are that the ascending air that utilizes the waste heat of waste gas own to form converges at and can rise rapidly in the enclosure that to be discharged into outdoor method by chimney very easy, effectively, no longer need any smoke evacuation power set, remarkable in economical benefits.

The utility model has the advantages that: the mode of this discharging waste gas can make indoor generation certain negative pressure, can the suction chamber outer air pass through in certain channel inlet chamber, with that part air that compensation water heater burning work is consumed, more help user of service's health and safety compared with original gravity-flow ventilation method.

Concrete structure of the present utility model is drawn by following embodiment accompanying drawing:

Fig. 1: a kind of gas heater enclosure schematic diagram: 1., enclosure; 2., chimney, 3., gas heater.

Fig. 2: a kind of gas heater enclosure schematic diagram: 4.: little enclosure.

For ease of understanding basic structure principle of the present utility model, be described with reference to the accompanying drawings: outside the gas heater upper port steam vent position on being fixed in wall shown in Figure 1, the cover that utilizes bore to be slightly larger than the rectangular opening cone shape of water heater upper end size is enclosed within burner water heater's upper port position and is fixed on the wall, the upper port of this rectangle lower port cone cover is a circular short sleeve, be used for connecting with the similar chimney of bore, the bore of rectangular opening is slightly larger than gas heater upper end size, its objective is and help to prevent to discharge fume smooth or the wind sky causes the normal combustion work of returning the wind effect water heater, the big moment that when burning produced presses around the enclosure space to overflow to loose, to guarantee the stable of water heater combustion flame.Little enclosure shown in Fig. 2 is the attachment device that helps to strengthen smoke discharging effect, the size of little enclosure and gas heater upper port size are identical substantially, appearance and size is slightly less than enclosure rectangular opening size, it is shaped as a rectangle tubular, its effect is the rate of climb when improving the waste gas generation, make it more effectively to concentrate on the cover in give off rapidly outdoor, to reduce in the part waste gas inlet chamber that may overflow at home and abroad from the slit on cover limit, can improve the negative pressure outside the slit, improve the free rate of waste gas.

For the ease of easy installation, under the situation that does not influence gas heater installation strength safety, enclosure can be erected at gas heater upper end suit and fix.

Claims (1)

1: a kind of enclosure that is used for the gas heater discharging waste gas, it is characterized in that rectangle in the bullet enclosure lower port 1., upper port is a circular short sleeve, is with rectangle tubular float petticoat pipe that a bore is slightly less than port sizes 4. in the rectangle lower port.
