Abstract

The utility model relates to a raging-fire gas stove capable of adjusting thermal power, which comprises a stove body, a combustion burner, a gas valve and a knob switch, wherein the combustion burner, the gas valve and the knob switch are mounted on the stove body; a strong-fire gas supply pipe and a weak-fire gas supply pipe are connected between the combustion burner and the gas valve; the strong-fire gas supply pipe is connected with a blower; a ventilation door is arranged at the air inlet of the blower; and a ventilation door control rod is connected between the ventilation door and the knob switch. In the gas stove, the ventilation door of the blower and the gas valve can be adjusted simultaneously; while the knob switch is rotated to reduce the gas supply from the gas valve to the combustion burner, the ventilation door of the blower is also narrowed, so that the air discharge amount is reduced, and the wind power of the blower is weakened. Therefore, the flame of the combustion burner cannot be blown out by wind.

Description

Firepower adjustable fire gas stove

technical field

The utility model relates to a gas stove, in particular to a gas stove with adjustable firepower and high fire used in households.

Background technique

The utility model patent No. 201020100758.X discloses a household high-fire gas stove, comprising a stove body and a burner burner installed on the stove body, a gas inlet pipe, and a gas valve, which is provided with a rotary switch. There are large fire gas supply pipe and small fire gas supply pipe connected between the combustion burner head and the gas valve. The large fire gas supply pipe is equipped with a solenoid valve switch to control the on-off of the large fire gas supply pipe. The large fire gas supply pipe is the main gas supply pipe of the combustion burner head. The main flame of the gas stove is ignited by the high fire gas supply pipe to the combustion burner. The rotary switch is ignited by the electronic igniter, and cooperates with the solenoid valve switch on the large fire gas supply pipe to control the on-off of the combustion burner gas.

In order to make the flame of the gas cooker more vigorous and powerful, the above-mentioned gas cooker is connected with a blower fan on the large fire gas supply pipe, and the low-voltage DC power supply installed on the cooker body supplies power for the blower fan, and the electronic igniter is powered by a dry battery. When the gas stove is burning, the blower starts, and the wind is sent to the burning burner through the large fire gas supply pipe, so that the burning flame of the burning burner is vigorous and powerful.

During the working process of the gas stove, sometimes it is necessary to control the size of the flame, that is, to rotate the knob switch to reduce the gas supply of the gas valve to the burner head. The opening of the valve is reduced to adapt to the reduction of gas supply. However, since the control of the gas valve of the above-mentioned gas stove and the control of the fan damper are independent of each other, when the gas valve is adjusted by rotating the rotary switch, the air volume output by the fan does not decrease, which easily causes the flame of the burner to be blown by the fan. off, causing inconvenience to users.

Contents of the invention

The purpose of the utility model is to provide an adjustable firepower gas stove, when the rotary switch is turned to reduce the gas supply of the gas valve to the burner head, the flame of the burner head will not be blown out by the fan.

The firepower adjustable high-fire gas stove of the utility model includes a stove body, a combustion burner installed on the stove body, a gas valve, a rotary switch for controlling the gas valve, and a high-fire gas supply pipe is connected between the combustion burner and the gas valve. And the small fire air supply pipe, the large fire air supply pipe is connected with a fan, the air inlet of the fan is provided with a damper for changing the size of the air inlet, and a damper control rod is connected between the damper and the rotary switch. When the rotary switch is turned to At the maximum position, the air inlet is fully opened, and when the rotary switch is closed, the air inlet is completely closed by the damper.

The air door is hinged on the blower fan through a pin shaft, one end of the air door control rod is hinged with the air door, and the other end is hinged with a swing rod fixed on the rotary switch shaft.

The rotary switch drives the air door to rotate through the air door control rod, so that the air door is fully opened, fully closed and partially closed to the air inlet of the fan, thereby adjusting the size of the air inlet of the fan.

During the working process of the gas stove, when the gas valve is opened to the maximum, the damper does not close the air inlet of the fan, and the air inlet of the fan is fully open. When it is necessary to reduce the flame of the burner head, turn the rotary switch to reduce the gas supply of the gas valve to the burner head. The rotation of the rotary switch drives the damper to rotate around its hinge pin with the fan through the damper control rod. The air door is made to partially close the air inlet of the fan, and since the air inlet of the fan is reduced, the air supply volume of the fan to the combustion burner is reduced, so that the flame of the combustion burner will not be blown out by the fan.

A power converter is installed on the stove body, which is electrically connected to a 12v low-voltage DC power supply. The power converter has three output terminals of 12v, 9v and 3v. Electrically connected with electronic igniter.

The power converter converts the 12v low-voltage DC power supply into 3V power supply for the electronic igniter to ignite instantly. At the same time, the two output terminals of the power converter 12v and 9v can selectively supply power to the fan through the switch, so that the fan has two different Rotating speed.

According to the utility model, the firepower adjustable high-fire gas stove is connected with the damper control rod between the rotary switch shaft and the fan damper, so that the adjustment of the damper and the adjustment of the gas valve can be carried out synchronously. When the valve controls the gas supply to the burner head, the air door of the fan is also adjusted down, thereby reducing the air output of the fan, resulting in a decrease in the wind power of the fan, so the flame of the burner head will not be blown out by the fan.
