Abstract
The utility model discloses a neglected shut-off and flameout protecting device for gas cooker, used for the protection of neglected shut-off of the gas cooker caused by gas cutting-off of the pipeline, or, an accidental flameout. The utility model is provided with a power source, an alarm device and a power switch between the gas cooker and a switch of the gas cooker. The utility model has the advantages of simple structure and low cost, and can be conveniently installed on the present new or old gas cooker.
Description
The utility model relates to a kind of gas kitchen ranges and leaks pass, blowout protection device.
The existing used guard method of gas kitchen ranges has begun to use thermocouple assembly, and as Japan Patent JP58-6323 and DRP DE3206042, it mainly produces thermocurrent by thermocouple, makes magnetic valve open the burner valve; When burner did not burn, thermocurrent disappeared, closed electromagnetic valve burner valve, thus play the protection purpose.Its weak point be will with gas kitchen ranges global design, manufacturing, and complex structure, cost height.
In addition, existing some protective devices that use are to utilize gas-sensing probe to detect in the room behind a certain amount of fuel gas, report to the police or open exhaust fan.Its weak point is: when the gas kitchen ranges switch is leaked the pass because of dying, and can not preventative alarm and protection.And complex structure, the part combustible gas of overflowing during to general flue gas and igniting is known from experience the generation false alarm.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, when the gas kitchen ranges switch leak is closed because of dying, also can preventative alarm and protection, and be convenient to be installed in leakage pass, blowout protection device on the existing burner.
The purpose of this utility model is achieved in that near burner flame, is provided with fiery quick probe, between burner switch and burner body power switch is housed.After opening the burner switch, connect power switch.At this moment, if the burner burning, fiery quick probe is not worked telltale.If burner does not have burning (accident extinguishing, the artificial leakage closed), fiery quick probe makes telltale work.
For preventing false alarm, on power supply and telltale loop, preferably add delay switch, make power switch for a moment closed, connect power supply again.The quick probe of fire can be a bimetal leaf, can also be thermosensitive probe or photosensitive probe.
The utility model only needs to adorn a power switch between burner switch and burner body, and a fiery quick probe is set near burner flame.All the other telltales, delay switch and power supply all can become one and be contained in arbitrary convenient place.So structure is very simple, and is with low cost, and can be installed in easily on the existing burner.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Figure one closes for the combustion gas tool leaks, the structure principle chart of blowout protection device.
Figure two is conductive contact blade, structure of contact terminal schematic diagram.
Describe in detail according to concrete structure principle and the working condition that the utility model proposes below in conjunction with figure one.
Open the burner switch, conductive contact blade (1) and contact (2) closure, through delay switch (3) time-delay for a moment, (in case false alarm) connects power supply (6).At this moment, the burner burning is arranged near the bimetal leaf (4) of burner flame and has been subjected to thermal cutoff, and telltale (5) is not worked.If burner extinguishes because of reason accidents such as wind, Tang Yi, or because of the leakage pass, burner switch (10) unlatching back of dying, bimetal leaf (4) cooling closure, circuit is connected, and telltale (5) is worked.Close burner switch (10), conductive contact blade (1) disconnects with contact (2), and circuit disconnects.
Conductive contact blade, the structural representation of contact is provided by figure two.
Conductive contact blade (1) is fixed in the burner switch rotating shaft (8) across insulation sleeve (7), when burner switch (10) is opened, after driving conductive contact blade (1) rotation, just with contact (2) closure that is fixed on the burner body (9), after closing burner switch (10), conductive contact blade (1) disconnects with contact (2).
Claims (4)
1, a kind of gas kitchen ranges leaks pass, blowout protection device, and it comprises power supply, fiery quick probe, telltale, it is characterized in that between burner body and the burner switch power switch being housed.
2, protector according to claim 1 is characterized in that the quick probe of described fire is bimetal leaf or thermosensitive probe or photosensitive probe.
3, protector according to claim 1 is characterized in that described power supply, telltale have delay switch on the loop.
4, protector according to claim 1 is characterized in that described power switch is conductive contact blade and the contact that is contained in respectively on burner switch and the burner body.
