Description
This " general electric rice cooker electricity-saving appliance " developed at reducing the employed all kinds of Domestic Electric Cooker power consumption of present users.After electric rice cooker is loaded onto this device.Several advantages are arranged again thereupon:
(1) economize on electricity 15%-30%;
(2) do not pounce on pot during cook porridge and rice;
(3) be difficult for during the Steamed chicken egg old;
(4) useful life of increase electric rice cooker;
(5) cook at the bottom of the Non-burnt pot;
(6) obviously reduce excessive infringement of overflowing steam to indoor environment;
(7) reduce owing to a large amount of voltages that use electric rice cooker to cause reduce;
(8) burden of transformer and transmission line during the alleviation peak of power consumption;
(9) this electricity-saving appliance carries one of three-plug connector and can be the user and save and purchase three-plug connector.
The present invention is to be theoretical foundation according to culinary art thing in the electric rice cooker at the different heats of different cooking stage needs.Reduce unnecessary electric energy input as far as possible.The task of this device is exactly constantly by detecting the temperature in the pot, recognize each cooking stage, and then the electric energy of control input electric rice cooker is the suitableeest state.Electric rice cooker is installed structure and the performance that does not change original electric rice cooker behind this device.Do not influence the time of cooking and cooking quality, device itself is each other independently with former electric rice cooker.Consider that each family does the difference of appetite, some difference of power savings (economize on electricity percentage) is generally 15%-30%, can economize on electricity about 25%-26% by three-person household.
This apparatus structure is simple, and is cheap.Total event oneself processing only needs an injection molding machine or hot press and a small-sized punch press.Certainly all part buyable or external coordinations can be saved equipment investment so again.Instrument only needs electric iron, universal instrument and thermometer etc.
Its structure of following division and operation principle:
This device mainly is by temperature survey part (figure three) and adjusts power section (figure five) and connecting line (2,10) form, its temperature survey is one and also is sealed in the plastic casing (11) and has bimetal leaf (8) thermal relay (figure three) and resistance capaciting absorpting circuit (14) is formed.Adjusting power section then is to be made up of a diode (5,21) that is encapsulated in the three-plug connector (figure five).The important in good time breaker device (figure six) of another one has guaranteed the function of electric rice cooker normal cutoff power supply.During use temperature measuring equipment (figure three) is placed on the lid of electric cooking-vessel (6), temperature measuring equipment colludes on the hook (4) that is fixed on the Button for cooker lid (5) by earrings (7), and it plays a part to prevent that temperature measuring equipment from coming off.And the three-plug connector after the transformation of the way is identical with the mode of connection of original socket, and it has three effects, the one, and to the electric rice cooker power supply, the 2nd, play protection electronic component and heat radiation (20) effect, the 3rd, provide the branch wiring to temperature measuring equipment.
Just can practical application after having installed circuit, at first the culinary art thing is put well, build pot cover, then temperature measuring equipment is placed on the pot cover, and by means of the hook (4) prevent that it from coming off, the plug of electric rice cooker is inserted energized, press the electric rice cooker turn-on key, electric rice cooker just begins automatically to have worked.
Phase I--the bringing-up section of culinary art, the power that is input to electric rice cooker in this stage is total power.That is:
P
1=P specified (electric rice cooker rated power)
Under this total power, the culinary art thing heats up rapidly in the pot, so promptly can shorten the temperature rise time, reduces to be dispersed into the heat in space, can make the rice in the pot reduce soak time again, thereby improve cooking quality, and save a part of electric energy.
When being elevated to 95-96C, temperature (sets) by adjusting screw (12), bimetal leaf (8) in the thermometric degree device has produced distortion, make its with contact (13) disconnect, diode just seals in circuit immediately, from then on electric rice cooker enters second stage--boiling section, forward current passes through in this stage, and reverse current is limited.Thereby make
P
2≤ 1/2 P is specified
In this stage because electrical power reduces, in the pot boiling normal, avoided original electric rice cooker when being unkitted electricity-saving appliance when boiling section since too much a series of bad phenomenon of causing of input electric energy as pouncing on pot, be burned and wasting the electric energy phenomenon.The culinary art thing is under this input heat state in the pot, and both power savings are best input electric power state again substantially, moisture in pot descends, and temperature rises to some extent, the auto-power-off device action of pot and till cutting off the electricity supply, so entered phase III--the section of cooking rice over a slow fire, the electrical power of its input:
P
3＝0
In the stage of cooking rice over a slow fire, the electrical power in the input pot is zero, and the culinary art thing relies on the waste heat of second stage in the pot, makes meal well-done, approximately carries out about 15 minutes, just can have a meal, if do not have a meal at once, electric rice cooker just enters quadravalence section--holding stage so.
P
4=P temperature control
In this stage, electric rice cooker relies on the adjusting device in the original pot, and the temperature of culinary art thing in the pot is remained on about 60 ℃,--irrelevant with this electricity-saving appliance.
Should point out at this: power savings is from aspect two:
(1) reduces the electric energy W that excessive boiling is saved for normal fluidized state
1
(2) need add certain water yield less owing to reduced the boiling degree, the electric energy that the heating of this part water yield needs is saved.Be expressed as W
2
So total saving electric energy is:
W＝W
1＋W
2
In addition, this device not only is applicable to electric rice cooker, also can be used on the electric heaters such as electric wok.(its main electricity principle is still and makes excessive boiling be adjusted into normal boiling).
In addition, because every family uses the electric rice cooker time quite concentrated, this moment is peak of power consumption time just also, all installs this battery saving arrangement as every family, then can reduce the load of transformer and the voltage drop and the loss of circuit greatly.The dispersiveness that connects the electric rice cooker power line when centrality and the every family considered with the electric rice cooker time.So this power-saving method is to powering without any adverse effect.
This device has adopted resistance capaciting absorpting circuit.Switch interference reduction when contact is disconnected is to disturbing also little this weak jamming of degree (to television set and broadcast receiver) only to occur once in a meal than general light switch, and all the other the experiment proved that all noiseless phenomenon constantly.
Following experimental data table has been introduced power savings (percentage) value when three-person household is cooked.It is worthy of note:
From relative number, few economize on electricity percentage of cooking is big, but amount of electricity saving is little.
From absolute number, the more piece of cooking electric weight is many, but economize on electricity percentage is little.
Figure six is the electric rice cooker adjusters that in good time cut off the power supply, it also is the anti-adjuster that is burned, it is that fixed screw (22) on the support is fixed on the automatic trip outage crossbearer (29) under the electric rice cooker heat-generating disc, its spring leaf (23) front end is pressed on the edge (30) of automatic trip magnet steel outer cover, can adjust the pressure of spring leaf (23) with screw (24), its objective is to be used for carrying out automatically the adjustment of power-off time in good time and to prevent to be burned edge (30).
(24) be the ground pin pole piece, (25) are the attaching plug pole piece, and (27) are the weldering electronic component holder, and (26) are diode, and (28) are one of terminals screws.
