Description

Energy saving control device for gas furnace

technical field

The utility model relates to an energy-saving control device for a gas cooker, which belongs to the technical field of cooker energy-saving.

Background technique

Existing gas cooker is made of kitchen range top, intake pipe, intake valve etc. When using the existing gas stove for cooking, after the first dish is processed, it is generally necessary to remove the frying pan from the stove, pour the fried dishes into bowls and plates and other containers, wash the frying pan and put it back on the stove , During this period of time, the fire of the stove has been burning, which consumes a lot of energy and pollutes the environment. Or after a dish is processed, when the wok is taken away from the stove, the fire is extinguished, and the fried dishes are poured into bowls and plates and other containers, and the wok is cleaned and put back on the stove, and then the stove is lit. Although this saves gas, it not only increases the workload of the chef, but also makes dishes and controls the gas switch by hand, which is more likely to affect the hygiene of food.

The sliding rod travel switch is provided with a fixed screw rod, a set nut, a contact rod connector, a lock nut, a return spring, a fixed nut, a slide rod, a damping spring, a travel switch, a travel contact block, a switch box, and a fixed screw rod. Connected to the contact rod with a set nut, the contact rod and the sliding rod are connected as a whole through the connecting piece of the contact rod, the return spring and the damping spring are set on the sliding rod, the travel switch is set in the switch box, and the switch box has a The sliding rod cover is installed and fixed on the cooktop through the fixing nut, the contact rod connector is inserted into the upper section of the sliding rod cover, the stroke contact block is installed and connected to the end of the slide rod, the contact roll of the travel switch and the stroke contact The taper of the block contacts the connection. A control circuit and a time relay are arranged in the control box.

The utility model has the advantages of reasonable and compact structure, convenient use, energy saving, cost saving and pollution reduction. Automatically control the ignition and extinguishment of the stove, so that the stove can achieve "the pot is away from the fire, and the pot is on fire".

When in use, the wok is placed on the stove, the control device starts to work, the wok presses down the touch rod, and the touch rod drives the slide bar to move down; The normally open contact is closed, the solenoid valve circuit in the control box and the igniter circuit are connected, the solenoid valve valve is opened, the gas enters the furnace through the pipeline, and the igniter ignites the gas at the same time, and the igniter stops working after a delay of 5 seconds. Get ready for your next job. When the frying pan leaves the stove, the contact rod moves upward due to the action of the return spring, the sliding rod drives the travel contact piece to move upward, the normally open contact of the travel switch is disconnected, and the circuit in the control box is provided with a time relay, and the solenoid valve of the time relay is delayed. After 2 seconds, the solenoid valve closes the gas, and the stove flame goes out. When the frying pan got back on the stove within 2 seconds, the electromagnetic valve continued to open, and the gas entered the furnace through the pipeline to continue burning. When the wok finishes frying a dish and then returns to the stove, the control device starts to work repeatedly.

When the controller cannot work due to unexpected reasons (such as inaccurate ignition rod gap, circuit failure, etc.), you can turn off the power switch, stop the work of the controller, and switch to manual control, so that the work of the stove can continue and ensure Continuity of stove operation.

The utility model is very convenient to use and has obvious effect of saving energy, and can be used in restaurants, hotels, offices, school canteens and the like.

Detailed ways

Consists of fixed screw rod 4, set nut 5, contact rod connector 6, lock nut 7, return spring 8, fixed nut 9, slide rod 11, damping spring 12, travel switch 13, travel contact block 14, switch box 15 The mounting connection constitutes a slide rod limit switch. The fixed screw rod 4 is connected on the contact rod 3 with a set nut 5 . One end of the handle bar 3 is arranged on the stove 2, and the frying pan 1 is pressed on the handle bar 3 at the same time when it is placed on the stove. The feeler bar 3 and the slide bar 11 are connected as a whole through the feeler bar connecting piece 6, and the return spring and the damping spring are sleeved on the slide bar. Stroke switch 13 is arranged in switch box 15, has slide bar cover on the switch box, and slide bar cover is installed and fixed on the kitchen range top 10 by fixing nut 9, and the lower end of contact bar connector 6 is inserted and sleeved on the upper section of slide bar cover. The travel contact block 14 is installed and connected to the end of the slide bar 11 , and the touch roller of the travel switch 13 contacts and connects with the taper surface of the travel contact block 14 . Travel switch 13 is connected to control box 17 by wire 16 . Electromagnetic valve 18 is installed between the manual gate valve in the gas pipeline and furnace core 22. The power plug 20 is connected with the control box 17 and the blower fan 23 , and a power switch 19 is set between the power plug 20 and the control box 17 and the blower fan 23 . The control box 17 is connected with the solenoid valve 18 and the igniter 21 by wires.

The touch rod part of the gas furnace energy-saving control device is placed on the table top of the cooker, the travel switch part is placed under the table, and the control box part can be installed under the table to reduce the space occupied by the table. Switch box 15 is made of ABS plastics, is die-casted with slide bar cover above, and slide bar cover doubles as the fixed screw that switch box is connected with kitchen range top. The travel switch 13 is fixed in the switch box 15. Since the switch box 15 is die-cast as a whole, it has good sealing performance, can effectively prevent moisture from entering, and meets the harsh kitchen environment requirements. At the same time, the contact rod connector 6 is an umbrella structure. The connecting part between the touch bar 3 and the slide bar 11 is designed to be non-through, so that water will not enter the switch box along the slide bar when cooking. The control box 17 is provided with a control circuit and a time relay to ensure the stability, reliability and sensitivity of the work process. Both the control circuit and the time relay are composed of microelectronic circuits with high reliability. The time relay has two time settings, one is the frying pan time, which is set to 2 seconds, so that the stove will turn off only after the frying pan is left for 2 seconds, and the other is the ignition time control of the ignition rod, so that the ignition rod can be controlled Within 5 seconds, the ignition rod will not be energized for a long time and the working life will be shortened. The control box and other components are only connected by wires, which simplifies system installation. The air supply pipeline is equipped with a manual valve and an electromagnetic air valve. The manual valve is used to close the gas source after the cooking work is over to ensure safety. The solenoid valve is used to control the ventilation of the frying pan when it is on the stove, and cut off the gas supply when the frying pan leaves the stove, so as to achieve the purpose of energy saving.
