Abstract

The oil or gas energy-saving stove realizes automatic extinguishing when the frying (burning) pot leaves the stove, and automatically ignites when the pot returns to the stove, which overcomes the empty burning phenomenon existing in the existing oil and gas cooking stoves in public dining places. Including the stove, blower, fuel delivery pipe, the improvement is to add a contact that is installed on the stove and can be pushed by the pot when it is placed on the stove, and can automatically return when the pot leaves the stove, and a solenoid valve that is fixed on the stove and controlled by the contact A power switch, a solenoid valve installed on the fuel delivery pipe, and a pot-controlled flameout and ignition device composed of continuously ignited tinder at the small fuel output hole at the burning position on the stove. The positive effect of the utility model is that the ignition and extinguishment of the flame is automatically controlled by having a pot or no pot on the stove, eliminating the phenomenon that the stove is frequently burned without a pot for a short period of time in public dining places, and saving about one-third One kind of fuel, which reduces the temperature of the chef's operation room, reduces oxygen consumption and exhaust emissions.

Description

Oil or Gas Energy Saving Stoves

technical field

The utility model belongs to the technical field of heating, in particular to a cooking stove.

Background technique

Existing oil or gas stoves for cooking, ignition, flameout, and firepower adjustment are all manually controlled by knobs. Such stoves have a serious waste of fuel in the catering industry, that is, when the chef has fried (burned) a dish and put it on a plate (bowl), the frying (burning) pot has a process of leaving the stove. Because the chef can't spare his hands when loading dishes on the plate, and has to continue to cook the next dish, he can't take care of turning off the fire, so the stove is in a state of high fire and empty fire. It has been observed that the empty burning time of the stove accounts for 30-40% of the entire burning time, which not only causes more fuel waste, but also increases the temperature rise in the kitchen, oxygen reduction, and exhaust gas emissions.

Contents of the invention

The purpose of the utility model is to provide a kind of fuel oil or gas energy-saving cooker, which can automatically turn off the flame when the frying (burning) pot leaves the stove, and automatically ignite when the frying (burning) pot returns to the stove. The phenomenon of empty burning in public dining places.

The utility model comprises a stove head in which the fuel of an existing fuel oil or gas stove is mixed with combustion-supporting air and burned, a blower, an air supply pipe connecting the stove head and the blower fan, and a fuel delivery pipe connecting the stove head and an oil tank or a gas tank. It consists of contacts installed on the stove that can be pushed by the pot when the pot is placed, and can automatically return when the pot leaves the stove, a solenoid valve power switch that is fixed on the stove and controlled by the contact, a solenoid valve installed on the fuel delivery pipe, and the stove. The pot-controlled flameout and ignition device composed of the continuously ignited tinder at the small fuel output hole at the upper combustion position.

The working process of the utility model is that when there is a pot on the stove, the contact is pushed, and the displaced contact touches the power switch of the solenoid valve to make it connected, the electromagnetic coil of the solenoid valve is energized, the solenoid valve is opened, and the stove has sufficient fuel supply , burning the flame of need. When the pot is moved away from the stove, the contact returns to its position, the power switch of the solenoid valve is disengaged, the power switch is turned off, the solenoid valve closes the fuel delivery pipeline, no fuel is supplied to the stove, the flame is extinguished, only the fire is lit, and the pot is placed on the stove again , the contact is pushed again, the contact touches the power switch of the solenoid valve, the power is turned on, the solenoid valve operates, the fuel delivery pipe is opened, fuel is ejected from the stove, and the flame is re-formed after being ignited by the tinder.

The positive effect of the utility model is that the ignition and extinguishment of the flame is automatically controlled by having a pot on or without a pot on the stove head, which eliminates the phenomenon that the stove head frequently burns without a pot for a short period of time in public catering places, and saves about 1/3 The fuel reduces the temperature of the chef's operating room, reduces oxygen consumption and exhaust emissions.

Description of drawings

Accompanying drawing is the overall structure figure of the utility model.

Detailed ways

Referring to the accompanying drawings, select the existing stove head 1, the pot blower 2, the air supply pipe 3 connecting the stove head and the blower, and the fuel connecting the stove head and the oil tank or gas tank for use in the existing fuel oil or gas stove. Delivery pipe 4. Mount the rod contact 5 vertically on the cooker 1, and the contact 5 is fixed on the side of the cooker through a sleeve. There is a contact return spring between the sleeve and the contact, and the spring is sleeved on the contact. On the boss of the head, one end is supported on the boss in the casing. The upper end of the contact can be pushed for a certain distance by the pot placed on the stove, and the lower end of the contact extends out of the sleeve. The power switch 6 of the solenoid valve electromagnetic coil is installed at a position where the contact moves down and can be touched, and the power switch 6 connects the power supply and the solenoid valve 7. The solenoid valve 7 is installed on the fuel delivery pipe 4, and the solenoid valve is opened when it is energized and closed when it is de-energized. A section of thin metal tube 8 is fixed near the fuel nozzle of the cooktop, and the thin metal tube 8 is connected with the fuel delivery pipe 4 between the solenoid valve and the fuel source to connect the ignition fuel pipe 9 . The fuel is ignited at the outlet of the thin metal tube 8 to form a constant burning kindling. The spare fuel delivery pipes are connected in parallel on the fuel delivery pipes at both ends of the electromagnetic valve. There is a manual valve 10 on the air supply pipe, a manual valve 11 on the ignition fuel pipe 9, a manual valve 12 on the spare fuel delivery pipe, and a manual valve 12 on the common fuel delivery pipe. The pipe has a manual valve 13. Promptly constitute the fuel oil or gas energy-saving range of the present utility model.

Claims (1)

1, fuel oil or energy-saving fuel gas stove, comprise the kitchen range that the fuel of existing fuel oil or gas-cooker mixes and burns with combustion air, air blast, the ajutage that connects kitchen range and air blast, the fuel-supply pipe that connects kitchen range and oil tank or gas tank, the improvement of being done is to set up by being installed in when putting on the kitchen range pot to be promoted by pot, the contact of energy self-return when pot leaves kitchen range, be fixed on the power of electromagnetic valve switch that is subjected to contact control on the kitchen range, be installed in the magnetic valve on the fuel-supply pipe, the pot control that the kindling material that the tiny fuel outlet aperture of burning position continues to light on the kitchen range is formed is flame-out, igniter.
