Abstract

The utility model relates to a gas stove, which can work under three work conditions of opening, closing and timing closing. A timing gas closing valve is added in the order connection of a gas inlet pipe, an igniting switch, a connecting pipe for a range and a honeycomb range, causing that an original passage way is changed into the order connection of the gas inlet pipe, the timing gas closing valve, a gas guiding pipe, the igniting switch, the connecting pipe for a range and the gas range. A turn knob of the timing gas closing valve is rotated to an opening gear or a timing gear by people; a turn knob of the igniting switch is pressed and counterclockwise rotated, causing that fuel gas is ignited; thereby, the gas stove can work for a long time or automatically close at the set time of from zero hour to one hour. When the work of the gas stove can not be required, the turn knob of the timing gas closing valve can be rotated to a closing gear or the igniting switch is rotated to the closing gear, causing that the gas stove can stop working.

Description

Gas furnace

The utility model relates to the furnace unit that a kind of fuel gas buring is used, and especially can be operated in and open, closes, and regularly closes the gas furnace of three kinds of duties.

At present, known gas furnace structure is to be connected in series and to be formed by air inlet pipe, ignition switch, kitchen range adapter, gas-cooker, and combustion gas is connected, and passs after then ignition switch being advanced.Be rotated counterclockwise, after ignition switch was sent electric spark combustion gas is lighted, gas furnace was started working, and is long during this work, it to quit work and must close retaining to the cycle of ignition switch knob.But many people have forgotten sometimes ignition switch is screwed into and have closed retaining, such as sometimes because of there being the guest to arrive, when going to take in guests and forgotten to close fire, at this moment gas furnace just is in and works long hours, and just might the thing that boil be burnt out, more likely initiation fire is given society, and family causes economic loss.

The purpose of this utility model provides a kind of gas furnace, it not only can work long hours, and can open in that select time was set in time 0-1 hour, after the stipulated time, can close automatically, thereby gas furnace can be operated in to be opened, close, but regularly close three kinds of duties at 0-1 hour select time.

The utility model is to realize like this, in metallic support, air inlet pipe is regularly closed air valve, wireway, ignition switch, kitchen range is taken over, and gas-cooker is linked in sequence, and regularly closes the same wall that air valve and ignition switch are separately fixed at metallic support, outside support, stretch out a rotating shaft respectively, socket knob in the rotating shaft.Open when retaining when people forward timing pass air valve knob to, push and reverse the ignition switch knob and light combustion gas, gas furnace just can work long hours; Be provided with when opening retaining when people forward timing pass air valve knob to the time, push then and reverse the ignition switch knob and light combustion gas, gas furnace just can be worked in the time of selecting setting, just can close automatically after the stipulated time.When not needing work, can close retaining to the air valve knob cycle of timing pass or the ignition switch knob returned and close retaining, gas furnace just quits work.

Open owing to adopting such scheme, gas furnace being operated in, close, regularly close three kinds of duties, only add a timing in the gas passage and close air valve, simple in structure.
