Description

Kitchen protector

Technical field：The invention belongs to kitchen safety article class, it is by instrument box 1, circuit control part 2 and gas circuit portion 3 are divided to combine.

Background technology：Currently known technology, is mainly used in monitoring combustible gas leakage concentration, smokescope overload alarm Or electric equipment products because overvoltage, overheat and the security product _ of automatic protection but for because kitchen housewife it is careless _ and often exist During waiting meal ripe (such as steamed bun, Tun meat) _ see TV, play mobile phone, answer the call, knit a sweater ... and often will Pot is dryouied, and meal burnt etc. into phenomenon _ happen occasionally, or even under some unexpected extreme cases _ family in it is basic nobody, and cooker Still being continuing with _ the lighter burns cooker, severe one causes major accidents such as fire _ to preventing the security product of such situation, warp Retrieval is had no result, and commercially _ it also there are no the sale of such product.

The content of the invention：The present invention constitutes _ instrument box by instrument box 1,3 three parts of circuit control part 2 and air path part As shell, convenient fixed and assembling；Circuit control part is loaded in instrument box；The glass rotors gas flowmeter of air path part 8 loaded on instrument box front, is easy to observe gas flow size, micro differential pressure switch 9 (K2) is hidden in instrument box.

The content of the invention is summarized as follows (see Fig. 1) below：

Wherein：1_ instrument box 2_ circuit control parts (put with instrument box)

3_ air path part 4_ gas kitchen ranges

The effect of instrument box 1 _ convenience is fixed, assembles and protects；Circuit control part 2_ completes automatic control function；Gas circuit It is required that part 3_ is used for gas kitchen ranges.Especially, if this device is used in pure electrical equipment kitchen range, such as electromagnetic oven, light-wave cooker, Then air path part is fully phased out.

Brief description of the drawings

Fig. 1 is instrument structure sketch map；

Fig. 2 is instrument structure detail drawing；

Fig. 3 is instrument electrical schematic diagram.

Wherein：1_ instrument box 2_ circuit control parts (loaded in case)

3_ air path part 4_ gas kitchen ranges

5_ source of the gas valve 6_ magnetic valves (normally closed)

7_ bypass valve 8- glass rotors gas flowmeters

As seen from Figure 2：Air path part 3_ is by source of the gas valve 5, magnetic valve 6, bypass valve 7, glass rotors gas flowmeter 8 and micro- Pressure difference switch 9 (K2) etc. is constituted.

Embodiment：Detailed circuit diagram (see Fig. 3)：

Now relevant symbolic significance in Fig. 3 is described as follows：

J is relay, and S1, S2, S3 are the time relay, and T is stop button, and Q is start button, and K1 opens for power supply Close, K2 is micro differential pressure switch 9, DT is band lamp, band locking press button (DT_D is its indicator lamp).

Now circuit structure is described below：

Be delayed break contactWith stop button T, start button Q, relay J, successively series winding access Civil power two ends, and J-1 contacts and the two ends for being connected in start button Q；The contact of J-2, J-3, J-4 tri- and company, and it is serially connected with live wire In, then contacted again with K1；Four jacks of socket 10 _ be connected to the civil power two ends after K1, the difference mechanical, electrical magnetic of fuel feeding cigarette successively Valve 6, electromagnetic oven are used, and the 4th jack is standby；Behind S1 two ends and DT 1-0 ends series winding, the electricity of the civil power after K1 is connected to Source, and DT-D indicator lamps and the two ends for being connected in S1；DT 2 ends are connected with S3 one end, S3 another line of termination civil power 0；Delay Contact S1-1 one end is closed, the line of civil power 0, another termination S2 one end and K2 common port 0 is connect；S2 another termination acousto-optic report One end of alert device 13, and be connected with the live wire after K1；K2 10 line of termination, K2 2 ends and the other end phase of audible-visual annunciator 13 Even.

Now operation principle is described below：

Instrument power plug is inserted into power outlet, K1 is also preliminarily placed in the position of " logical ", and the gas circuit of gas-cooker is connect by figure It is good, by-passing valve 7 is closed, then in the case where being not powered on, because magnetic valve 6 (normally closed) is off state, therefore gas circuit is obstructed.This When：

First, start button Q, J-1 self-insurance adhesive is pressed, then relay J obtains electric, the equal adhesive of J-2, J-3 and J-4, therefore electric Road is powered, and lampblack absorber obtains electric work, and magnetic valve 6, which is powered, to be opened, and it is that can be used now to open gas stove switch, and flowmeter 8 is shown Gas flow, micro differential pressure switch 9 (K2) action, connects 0-2, i.e. audible-visual annunciator 13 and S2 is simultaneously even stand-by；Other electromagnetic oven Also it is powered stand-by.

2nd, S1 is used for circular flow in short-term (such as steamed bun), for example, be set to 10 minutes (The times _ can be according to personal habits And concrete condition, arbitrarily set)；S2 is used for sound and light alarm, is set to 1.5 minutes；Timing (time _ can root when S3 is used for long According to personal habits and concrete condition, arbitrarily set) operation (such as Tun meat, stewing rice), for example it is set to 30 minutes, is applicable respectively In different situations, selected for user.

3rd, press after start button Q, press DT buttons, make DT_D lamps bright, i.e., indication circuit enters circular flow shape in short-term State, S1 i.e. with other electrical equipment it is electric, timing 10 assign to after, delay close contact S1-1 act, S2 obtain electric then sound and light alarm _ Remind housewife's processing：For example _ and such as still need to recycling work in 10 minutes, then DT is pressed, DT_D lamps go out, sound and light alarm stops, then presses Once DT resets, and DT-D lamps are bright, then S1 again it is electric _ work on, until run 10 minutes again after, S1-1 is closed again On, then second of sound and light alarm ... repeats above step as that need to continue cycling through.

If the 4th, after sound and light alarm, user is in 1.5 minutes of setting, and handle _ be not delayed then break contact in timeIt will act, then relay J dead electricity, J-1 to J-4 breaks entirely, and circuit dead electricity, all electrical equipment are powered off, therefore magnetic valve 6 Also automatically shutting down gas circuit _ flame-out ensures safety.

Timing operation mode of operation when the 5th, such as using long, is operated as follows：

1st, by start button Q, then be powered work；

2nd, DT is pressed, DT-D lamps is gone out, now DT 0_2 is connected, (and 0 _ 1 disconnected, S1 dead electricity, then the first pattern is automatic Stop.) then S3 obtain after electric _ continuous firing 30 minutes, be delayed break contactDisconnect, then relay J dead electricity, own Electrical equipment powers off, died.

6th, the design also has individual advantage _ electric-linked：Stop button T is pressed, then powers off, die；Conversely, shut-off stove Switch _ on tool and forgotten also worry by stop button T (some careless housewives are often such ...), now due to minute-pressure The effect of difference switch 9 (i.e. the 0_1 that K2 acted _ made K2 is connected, and causes S2 to obtain electric), after 1.5 minutes _ delay break contactIt will act, cause relay J1 dead electricity _ will also automatically power off both has saved the energy, is conducive to extending the use of magnetic valve 6 again Life-span.

7th, just because of two kinds of operational modes of the design _ be respectively provided with automatically power off, function of dying, even if so at home Under nobody extreme case _ also can reliably automatically power off, die, the generation of the major accidents such as fire can be prevented effectively from, it is ensured that Safety.

8th, it is not influence gas furnace to use under power-off condition, by-passing valve supply can be opened, when having electricity, then by by-passing valve Close.
