Abstract

The utility model relates to a timing control device, particularly a timing firepower controller for a gas cooker. A timing device and a resetting device are arranged on an ignition control device of an original gas cooker, and thus the goal of timing fire control is obtained. The utility model has the advantages of simple structure, convenient operation and no operating order.

Description

Gas-cooker is the firepower control device regularly

The utility model relates to a kind of timing control apparatus, and particularly a kind of gas-cooker is the firepower control device regularly.

Time set is not installed on the gas-cooker in the market, when preparing a meal, is usually needed the people and keep and be careful the duration and degree of heating aside, have mistake just to occur accident easily slightly.

The purpose of this utility model is to provide a kind of device that can control heat power of gas burner with timing mode.

The purpose of this utility model is achieved through the following channels: gas-cooker is the firepower control device regularly, the main shaft of flame switch turn-knob passes stove and connects with electronic ignition device, it is to have added time set and resetting means on original gas combustion range ignition control device, time set comprises the timing turn-knob that is the shape of blocking a shot that install the Mainspring type timer that is packed on the stove and outside thereof, be set with the main shaft of flame switch turn-knob in the hollow shaft of timer, hollow shaft and timing turn-knob are fixedly connected and connect with electronic ignition device; Resetting means is made up of the ratchet that resets, ratchet, fan-shaped clutch, torsionspring, paw and positive stop, the fan-shaped clutch wherein and the main shaft of flame switch turn-knob connect firmly, reset and be fixedly connected with positive stop and torsionspring on the ratchet, the other end and the stove of torsionspring connect firmly, and the differential seat angle between the fan groove of the ratchet that resets and the fan-shaped clutch is greater than the hard-over of flame switch turn-knob.Be fixed with a firepower controller regularly on the stove, the firepower controller is divided into " little fire " and reach " closing fire " two grades, and the gear button is controlled stretching out of dead bolt or withdrawn, when dead bolt stretches out just with the motion track interference of positive stop.

The utility model is simple in structure, and is easy to operate, do not have order of operation, is suitable for average family and uses.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A-A of Fig. 1 is to cutaway view;

Fig. 3 is that the B of Fig. 2 is to partial view;

Fig. 4 is the local structure for amplifying schematic diagram of Fig. 1.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the main shaft 15 of the flame switch turn-knob 1 of gas-cooker timing firepower control device passes stove 4 and connects with electronic ignition device 6, it is to have added time set and resetting means on original gas combustion range ignition control device, time set comprises the timing turn-knob 11 that is the shape of blocking a shot that install the Mainspring type timer 2 that is packed on the stove 4 and outside thereof, be set with the main shaft 15 of flame switch turn-knob 1 in the hollow shaft 16 of timer 2, hollow shaft 16 and timing turn-knob 11 connect firmly and connect with electronic ignition device 6; Resetting means is made up of the ratchet 3 that resets, ratchet 7, fan-shaped clutch 8, torsionspring 9, paw 13 and positive stop 14, fan-shaped clutch 8 wherein connects firmly with the main shaft 15 of flame switch turn-knob 1, reset and be fixedly connected with positive stop 14 and torsionspring 9 on the ratchet 3, the other end of torsionspring 9 and stove 4 connect firmly, and the fan groove of the ratchet 3 that resets and the differential seat angle between the fan-shaped clutch 8 are greater than the hard-over of flame switch turn-knob 1.Be fixed with a firepower controller 5 regularly on the stove 4, firepower controller 5 is divided into " little fire " and reach " closing fire " two grades, and gear button 18 is controlled stretching out of dead bolts 17 or withdrawn, when dead bolt 17 stretches out just with the motion track interference of positive stop 14.

Regularly the firepower control device course of work is as follows for this gas-cooker: when handle 1 left-handed opening fire, switch spindle drives fan-shaped clutch 8, reset ratchet 3 and fan-shaped clutch 8 initial positions as shown in Figure 2, then fan-shaped clutch 8 drives the ratchet 3 that resets and is rotated counterclockwise, screwing spring 9 is tightened simultaneously, torsionspring 9 just has the trend of resetting when the people unclamps hand, but by ratchet 7 resistance shelves, it is fixing that this moment, ratchet 7 made the ratchet 3 that resets, fan-shaped clutch 8 can rotate arbitrarily in the fan groove of ratchet 3 that resets, the main shaft 15 of switch turn-knob 1 also just can rotate in this angle, thereby control electronic striking device 6 and air valve reach and open fire, close the purpose of fire and control flare size.

Regularly firepower controller 5 has " little fire " reach " closing fire " two grades, when gear button 18 is positioned at " little fire " gear, dead bolt 17 stretch out with the ratchet 3 that resets on positive stop 14 offset, flame is turned in feasible ratchet 3 stalls that reset down; When gear button 18 is positioned at " closing fire " gear, dead bolt 17 withdrawals, the ratchet 3 that resets is not subjected to any stopping to go back to initial position, closes flame, and firepower controller 5 guarantees that with the design of dead bolt 17 timing and control fire do not have precedence.

When firepower is controlled in timing if desired, then 11 dextrorotation of timer turn-knob are to required scale, the initial position of paw 13 and ratchet 7 as shown in Figure 3, paw 13 can be by ratchet 7 resistance shelves during dextrorotation timer turn-knob 11, because the elastic force of spring leaf 13 is less than the elastic force of ratchet 7 springs, paw 13 can get out of the way.When timer 2 timing finish, paw 13 can be depressed ratchet 7, and the ratchet 3 that resets this moment can go back to initial position under the effect of torsionspring 8, and the ratchet 3 that resets drives fan-shaped clutch 8 and rewinds initial position, fan-shaped clutch 8 drives main shaft 15 and forwards fiery position, pass to, thereby shuts flame.This moment is when being in " little fire " gear as if timing firepower controller 5, then dead bolt 17 stretches out, when ratchet 3 stalls that reset, limited block 14 is by dead bolt 17 resistance shelves, make the ratchet 3 that resets rest on a certain angle, realize regularly turning down flare, wherein regularly the design of firepower controller 5 guarantees that timing and control fire do not have precedence.
