Abstract

The utility model provides a time controlled gas cooker, which forms by adding a timing valve at the normal gas cooker. The timing valve is compose of a timing switch 1, a thermocouple 2, an electromagnetic valve 3and the connecting lead, i.e. cluster a circuit timing switch into the thermocouple and the gas way electromagnetic valve circuit. When use, set the circuit timing switch according to the needed time, ignite the stove, the thermocouple will operate, the electromagnetic valve close the gas way, when the setting time is finished, the circuit timing switch cut the circuit between the thermocouple and the electromagnetic valve, the electromagnetic valve close the gas way, and the stove is flameout, so as to realize the time control. If need the vent valve also can be closed by hand, simultaneously has the flameout protection function, so as to ensure the safety use of the gas cooker. The main usage is the household gas stove.

Description

Time control gas kitchen ranges and Timed valve thereof

The utility model is the gas kitchen ranges with Timed valve, comprises gas-cooker, warmer, water heater etc.

With the gas-cooker is example, be extensive use of the gas-cooker of selling with the market at present and do not have timing function, in use, especially heat up water, steamed sweet bun, cook meat etc., every needs longer heat time heating times, often double other thing of doing of people, and forget and in time close kitchen range, the waste combustion gas, even dryout pot, the infringement apparatus also has to cause fire and gas explosion.

The purpose of this utility model be for provide a kind of assurance safely, prevent the new kitchen range that above accident takes place.Method is to change the magnetic valve that sell on the pulse kitchen range gas circuit with extinguish protection function the market into Timed valve, promptly seals in circuit timer switch in the circuit of thermocouple and electromagnetic valve of gas circuit and forms Timed valve.Circuit timer switch is screwed on the kitchen range shell.

The table top of first embodiment of the present utility model arranges that signal is as Fig. 1.1 is circuit timer switch, the 2nd among Fig. 1, thermocouple, the 4th, and manual air valve, the 5th, igniter, the 6th, kitchen range is that the magnetic valve with the left side of two kitchen range kitchen range changes Timed valve into.The Timed valve circuit as shown in Figure 2.Among Fig. 2, the 1st, circuit timer switch, the 2nd, thermocouple, the 3rd, magnetic valve is formed by the connecting conducting wire serial connection.Constantly uncertain, circuit timer switch 1 disconnects circuit.During use, circuit timer switch 1 is located at the required time position, at this moment (closing of circuit) pushed and rotated manual air valve 4, and kitchen range 6 is lighted in igniter 5 sparkings, and the thermocouple 2 that is heated is given magnetic valve 3 continued powers, unclamps manual air valve 4, kitchen range 6 normal combustion.When the setting-up time end of a period, circuit timer switch 1 disconnecting circuit, magnetic valve 3 cuts out gas circuit, and kitchen range 6 is flame-out, avoids because of forgetting that Guan Huoer makes kitchen range 6 long-time burnings cause adverse consequences.If when (time switch 1 closure) kitchen range 6 stopped working because of reasons such as wind, spilling waters during time control, thermocouple 2 temperature descended, stop magnetic valve 3 power supplies, magnetic valve 3 also will cut out gas circuit, play the blowout protection effect.

During time control, the user also can close manual air valve 4 as required in advance and stop working.

Fig. 3 is the schematic diagram that second embodiment table top of the utility model arranged, different with first embodiment is that two kitchen ranges add regularly valve respectively, and two kitchen ranges are carried out time control respectively, and operation principle is the same.

The 3rd embodiment of the utility model is that the Timed valve that will control two kitchen ranges among second embodiment respectively changes a public circuit timer switch (table top is arranged and circuit timer switch among Fig. 11 can be placed in the middle of the two manual air valves 4) into, circuit theory as shown in Figure 4, code name is the same among the figure.During use, circuit timer switch 1 is as required with long kitchen range setting burning time.The kitchen range that burning time is short, when end of cooking, this kitchen range of manual-lock.Another kitchen range is ended at setting-up time, closes automatically.Like this, both can reduce the control knob number and make the kitchen range table top succinct, and can need the kitchen range of longer burning time to carry out time control to any one again, increase the flexibility of using.

The utility model also is applicable to the kitchen range of or three and above kitchen range, and principle is the same.

Among the above each embodiment, do not need regularly circuit timer switch to be located at normally closed position if cook in short-term yet.Like this, just the same with common kitchen range, do not carry out time control.But, in order to ensure safety, what circuit timer switch can be with no normally closed position, must time control as long as promptly open fire, perhaps adopt the circuit timer switch of no normally closed position and normally closed function is located at the shelter with a handle switch branch, prepare against and meet an urgent need.

The used rapidoprint of the utility model is with kitchen range are the same usually, and thermocouple, magnetic valve, circuit timer switch all have the processing of typing producer.The both available mechanical also available electron formula of circuit timer switch.If with the time switch of electronic type, can also further design the remote control kitchen range.

The utility model is mainly household gas range, and other time control combustion gas tools such as time control warmer and time control water heater also all are to install Timed valve additional to form on the general gas tool.

Claims

1, a kind of combustion gas gas circuit Timed valve is characterized in that, it is by connecting conducting wire circuit timer switch, thermocouple and electromagnetic valve of gas circuit to be in series.

2, a kind of gas kitchen ranges with Timed valve is characterized in that, the gas circuit of gas kitchen ranges is equipped with combustion gas gas circuit Timed valve as claimed in claim 1.
