Description

Gas stove

Technical Field

The invention relates to a household gas stove, in particular to a strong-fire gas stove.

Background

The maximum thermal load (power) that a household gas cooker can reach when meeting various indexes of national standards, such as carbon monoxide content, thermal efficiency and the like, is called as the nominal maximum thermal load of the gas cooker. The existing household gas stove can only be adjusted within the range of the nominal maximum heat load, and a user of the combustion stove cannot obtain a cooking environment larger than the nominal maximum heat load, so that the requirements of modern household users cannot be completely met. Especially, some cooking modes such as quick-frying which need a strong fire to achieve the cooking effect cannot be achieved by a common gas stove. Some gas stoves adopt the design of binary channels double-nozzle to promote heat load, control first gas passageway, second valve control second gas passageway through the gas valve, and the gas valve adopts parallel mode to connect into main trachea with the second valve, has connect a gas circuit pipeline from main trachea more than ordinary gas stove, has increased a gas leakage's potential safety hazard relatively, has still increased product material, processing cost.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme. A gas stove comprises a main gas pipe, a gas valve, a first gas channel, a second valve, a nozzle and a burner, wherein the gas valve is communicated with the main gas pipe and the first gas channel; the gas valve is an adjustable valve, and the second valve is an on-off valve; the gas stove has a normal combustion state and a violent fire combustion state, and the gas valve is in the normal combustion state when opened and the second valve is closed; when the gas valve and the second valve are opened simultaneously, the gas valve and the second valve are in a violent fire combustion state; the gas valve, the second valve and the fan are connected in a signal mode, and the fan is started and stopped along with the on-off of the second valve; the gas valve can identify gears and is in signal connection with the controller, and the second valve and the starting fan can be opened through the controller only in a big fire gear, namely, a violent fire combustion state is started.

Further, when the opening degree of the gas valve is adjusted in the process of the violent flame combustion state, the controller closes the second valve and the fan after receiving the signal, and the gas stove is changed from the violent flame combustion state to the normal combustion state.

Further, the second valve is connected with a first gas channel at the rear end of the gas valve in an access mode.

The gas burner comprises a central fire burner, a third gas channel, a fourth gas channel, a third nozzle and a fourth nozzle, wherein the third gas channel, the fourth gas channel, the third nozzle and the fourth nozzle are corresponding to the central fire burner, the third gas channel is connected from a gas valve, and the fourth gas channel is connected from a second gas channel at the rear end of the second valve.

Further, the second valve is connected from the first gas channel or the third gas channel at the rear end of the gas valve.

Further, the controller is provided with a timing device, and the timing is started when the second valve is opened.

Further, the gas valve and the second valve are mechanical valves or electromagnetic valves.

The invention adopts a single-burner double-nozzle structure, and can realize the normal combustion state and the strong fire stir-frying combustion state of the stove according to a multi-channel gas supply structure of the stove. The gas valve and the second valve are connected in series, the gas valve is connected into the main gas pipe, and the second valve is connected into the gas valve. The gas valve of the gas stove is connected with only one first gas channel (outer ring fire gas pipe) and one third gas channel (center fire gas pipe), and the gas valve is connected with a common stove without difference, so that the gas channel is simplified, and the gas valve is safer. The gas stove provided by the invention can instantly realize heat load lifting, is converted from a normal combustion state into a violent fire combustion state, meets the requirements of people on stir-frying cooking, has various modes of closing the violent fire combustion state, can directly close the second valve and is timed and closed, and particularly can close the violent fire combustion state by rotating the gas valve according to the usual operation habit of people when the gas valve and the second valve are connected in series.

Drawings

Fig. 1 is a schematic structural view of a gas range of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, a gas range includes an outer ring fire and a center fire. The gas valve 2 is communicated with the main gas pipe 1 and the first gas channel 3, the second valve 12 is communicated with the gas valve 2 and the second gas channel 13, the first nozzle 5 and the second nozzle 15 extend into the main fire burner 7 side by side to inject the pipe, and the first nozzle 5 and the second nozzle 15 are respectively correspondingly communicated with the first gas channel 3 and the second gas channel 13. The central fire is provided with a third gas channel 4, a fourth gas channel 14, a third nozzle 6 and a fourth nozzle 16 which correspond to the central fire burner 8, wherein the third gas channel 4 is connected from the gas valve 2, and the fourth gas channel 14 is connected from a second gas channel 13 at the rear end of the second valve 12.

The gas stove has a normal combustion state and a violent fire stir-frying combustion state. The normal combustion state system consists of a main gas pipe 1, a gas valve 2, a first gas channel 3, a third gas channel 4, a first nozzle 5, a third nozzle 6, an outer ring fire burner 7 and a central fire burner 8. In the high fire stir-fry combustion state system, a second valve 12, a second gas channel 13, a fourth gas channel 14, a second nozzle 15 and a fourth nozzle 16 are added on the basis of a normal combustion state system, and in addition, a controller 10 and a fan 11 are also added. The gas valve 2 is a mechanical adjustable valve and can identify gears, and the second valve 12 is an electromagnetic on-off valve. The gas valve 2 is in a normal combustion state when being opened and the second valve 12 is closed; when the gas valve 2 and the second valve 12 are opened simultaneously, the gas valve is in a violent fire stir-frying combustion state. The controller 10 is in signal connection with the gas valve 2, the second valve 12 and the fan 11, and the fan 11 is started and stopped along with the on-off of the second valve 12; the gas valve 2 can identify gears and is connected with the controller 10 through signals, and the second valve 12 and the starting fan 11 can be opened through the controller 10 only when the gas valve 2 is in a big fire gear, namely, a violent fire combustion state is started. The controller 10 is provided with a timing device, the second valve 12 starts timing when being opened to enter a violent fire stir-frying combustion state, and the second valve 12 is automatically closed when the set time is reached, so that the gas stove is prevented from being in the violent fire stir-frying combustion state for a long time.

Set up "a key explodes to fry" and open and stop button on the gas-cooker panel, the gas-cooker is under the big fire state of normal combustion, click the button and start, can trun into the fierce fire to explode the stir-fry burning state rapidly, realize promoting heat load in the twinkling of an eye, satisfy people's stir-fry culinary art demand of exploding, it is various to close fierce fire burning state mode, can directly click the button and close, also can be by controller 10 timing automatic closing, especially can rotate gas valve 2 according to people's ordinary operating habits and adjust firepower and can close fierce fire burning state, when adjusting 2 apertures of gas valve in the fierce fire burning state process, controller 10 closes second valve 12 and fan 11 after receiving the signal, the gas-cooker truns into normal combustion state by fierce fire burning state.
