Technical Field

The invention relates to the technical field of cooking benches, in particular to a safe-use gas stove cooking bench.

Background

The gas cooker is a kitchen utensil heated by direct fire with liquefied petroleum gas (liquid), artificial gas, natural gas and other gas fuels, and is mainly divided into a liquefied gas cooker, a gas cooker and a natural gas cooker according to gas sources. According to the range, the range is divided into a single range, a double range and a multi-range.

In actual use, when the combustible gas is insufficiently combusted, carbon monoxide gas is generated and is inhaled through the respiratory tract to cause poisoning. The poisoning mechanism is that the affinity of carbon monoxide and hemoglobin is 200-300 times higher than that of oxygen and hemoglobin, so that carbon monoxide is easily combined with hemoglobin to form carboxyhemoglobin, so that the hemoglobin loses the oxygen carrying capacity and effect, and the tissue is suffocated. The gas stove cooking bench has a toxic effect on tissue cells of the whole body, particularly has the most serious influence on cerebral cortex, and is easy to cause larger harm due to colorless and odorless carbon monoxide.

Disclosure of Invention

The invention aims to solve the problem that toxic gases such as carbon monoxide and the like are easily generated when a gas stove in the prior art is incompletely combusted, and provides a safe-used gas stove hearth.

In order to achieve the purpose, the invention adopts the following technical scheme: a safe gas stove cooking bench comprises a fixed bench and a stove stand, wherein a gas transmission pipeline and a return pipe are respectively arranged in the stove stand, the return pipe penetrates through the stove stand and is communicated with a treatment space in the fixed bench, a heat conduction layer is arranged above the treatment space, the heat conduction layer is communicated with the outside and is provided with a fire maker on one side close to the gas transmission pipeline, the heat conduction layer is connected with a heat transfer plate, a vent hole is formed in the heat transfer plate in a penetrating manner, the vent hole is connected with a one-way valve in a sealing manner, one end, far away from the return pipe, of the treatment space is provided with a gas outlet pipe;

one side of the processing space, which is close to the air outlet pipe, is fixedly connected with a photosensitive layer, the photosensitive layer is electrically connected with a photoresistor, the photosensitive layer is fixedly connected with a searchlight, the heat transfer plate adopts a light-scattering structure and is made of ferric oxide;

the bottom of the heat transfer plate is connected with the bottom wall of the processing space in a sliding mode through a T-shaped sliding block structure, a sliding groove is formed in the size of the bottom wall of the processing space matched with the size of the T-shaped sliding block structure, and the sliding groove and the sliding block are fixedly connected with an automatic telescopic rod together.

In the safe gas stove top, the searchlight and the photosensitive layer are yellow, the gas transmission pipeline is internally and hermetically connected with an electromagnetic valve, the electromagnetic valve is electrically connected with the photosensitive resistor, and the joint of the return pipe and the treatment space is hermetically connected with a one-way valve.

Compared with the prior art, the invention has the advantages that:

1. when the gas stove is used, the combustible gas is output by the gas pipeline in the stove stand and ignited under the action of the igniter, and the combustion position is positioned above the heat conduction layer, so the heat conduction layer and the heat transfer plate are simultaneously in a high-temperature state, and at the moment, the automatic telescopic rod at the bottom of the heat transfer plate is controlled by the alternating magnetic field to realize the reciprocating motion of the heat transfer plate in the processing space, so that the air at the flame position is pumped out to the processing space by the return pipe;

2. in the air exhaust process, when the heat transfer plate moves to one side of the gas transmission pipeline, external gas is pumped into the processing space, when the heat transfer plate moves to one side of the return pipe, the gas in the processing space is pressed into the other side under the action of air pressure and the action of the one-way valve and is fully contacted with the surface of the heat transfer plate in the process, when the gas components do not contain carbon monoxide, the components in the air do not react with the heat transfer plate at high temperature, and when the gas absorbed into the processing space contains carbon monoxide, the heat transfer plate with the ferric oxide structure and the carbon monoxide are combined at high temperature to produce carbon dioxide and iron molecules;

3. because the return pipe extracts gas from the combustion point, the oxygen content is negligible, therefore, under the condition that the combustible gas is not combusted sufficiently, the carbon monoxide extracted into the processing space fully reacts with the heat transfer plate close to one side of the return pipe, so that the surface of the heat transfer plate is completely converted into iron, the color of the heat transfer plate is changed from red to silver white, and the other side of the heat transfer plate is directly contacted with air, so that the heat transfer plate still keeps in a red state, the heat transfer plate forms a state of a convex mirror at the moment, and the probe illumination light irradiated on the heat transfer plate is reflected to the photosensitive layer;

4. photosensitive layer and searchlighting set up to yellow, when the heat transfer plate composition was ferric oxide completely, self will be red, yellow searchlighting illumination can be absorbed by the heat transfer plate completely this moment, thereby can't reflect to photosensitive layer, then the photo resistance opens the solenoid valve in the gas transmission pipeline, make can normally supply gas, and when the one side of heat transfer plate turned into silver-white iron, because silver-white can reflect the yellow light this moment, therefore photosensitive layer detects illumination, make photo resistance close the solenoid valve, make unable output combustible gas, and the burning will automatic stop.

5. After the combustion stops, because the heat transfer plate is close to one side of the return pipe and is communicated with the outside, the heat is dissipated quickly, one side close to the return pipe is in a closed state under the state that the one-way valve is closed, after the heat is dissipated completely at the other side, the heat transfer plate can move to one side of the gas transmission pipeline under the action of thermal pressure, so that the outside air is driven to enter the processing space, and because the heat transfer plate is still at high temperature, the oxygen in the air can rapidly generate redox reaction with iron powder, so that the surface of the heat transfer plate is covered by the ferric oxide again, and the heat transfer plate is convenient to use next time.
