Abstract
The utility model relates to an electric rice cooker timing socket and belongs to a timing device by utilizing a conductive time delay relay to control conductive rice cooking time of an electric rice cooker. 220V live wire is connected with a moving contact of a conversion switch K, a first constant contact of the K is connected with a first wiring terminal of a three-jack socket CZ, a second wiring terminal of the CZ is connected with a zero wire N, a second constant contact of the K is connected in series with a normally closed contact 2KT1 of a second time delay relay 2KT and a first time delay relay 1KT in order and then connected with the zero wire N, one end of a first normally opened contact 1KT1 of the 1KT is connected with the 2KT1 of the 2KT and a node of the 1KT, the other end of the 1KT1 is connected in series with the 2KT and then connected with the zero wire N, the second constant contact of the K is connected in series with a second normally opened contact 1KT2 of the 1KT and then connected with the first wiring terminal of the CZ. Automatic conduction is realized in a setting time segment, rice is well cooked in the setting time segment; disconnection is realized automatically; and automation of a whole rice cooking process is realized. The electric rice cooker timing socket has advantages of simple circuit structure and great convenience in use.
Description
Technical field
The utility model relates to electric rice cooker control device conduction time, particularly adopts the cook timing device of time of energization delay relay control electric rice cooker energising.
Background technology
Electric rice cooker is plugged the energising of 220V power supply with the resistance wire stone or metal plate for standing a stove on as a precaution against fire of electric rice cooker and can be cooked when cooking use.After meal is cooked, artificial deenergization again.People need to be automatically auto-breaking behind the cooked, and existing electric rice cooker can not satisfy the demand be cooked in plugged and at the appointed time energising sometime.
The utility model content
The purpose of this utility model provides a kind of timing Power-On that has, the electric rice cooker regular socket of auto-breaking behind the cooked.
This novel purpose is achieved in that a kind of electric rice cooker regular socket, comprise Three-hole socket CZ, 220V live wire L is connected to the moving contact of change over switch K, first of change over switch K decides the first binding post that contact a is connected to described Three-hole socket CZ, the second binding post of Three-hole socket CZ is connected to zero line N, second of change over switch K decides to be connected to zero line N after contact b is connected in series the normally closed interlock 2KT1 of the second energization delay relay 2KT and the first energization delay relay 1KT in turn, the first normally open contact 1,KT1 one of the first energization delay relay 1KT is terminated at the normally closed interlock 2KT1 of the second energization delay relay 2KT and the node of the first energization delay relay 1KT, be connected to zero line N after this first normally open contact 1KT1 other end is connected in series the second energization delay relay 2KT, second of change over switch K decides to be connected to behind the second normally open contact 1KT2 that contact b is connected in series the first energization delay relay 1KT the first binding post of Three-hole socket CZ.
Be connected with the indicator light LD that cooks between first, second binding post of described Three-hole socket CZ.
This socket is that handle affairs for going to work, go to school, going out this class people who cooks that can not in time go home in a hurry designs specially, (selection voltage is 220V to increase an energization delay relay, delay time was advisable at 2～6 hours, also can select as required different energization delay relays).When you leave home working, handle affairs when can not go home on time, before leaving home, add rice and water in the electric rice cooker, change over switch beaten to second decide contact, namely connect second and decide contact (at this moment, this socket live wire L also claim phase line, and zero line N also claims center line), plug is inserted supply socket, i.e. access 220 alternating currents between L and the N; And the plug of the resistance wire stone or metal plate for standing a stove on as a precaution against fire of electric rice cooker inserts in the Three-hole socket CZ), if be 3 hours during the first energization delay relay 1KT logical, then the 220V alternating current is through normally closed contact 2KT1 and 1KT, 1KT powered on after 3 hours, two normally open contact 1KT1 and 1KT2 are all closed, because the closure of 1KT2, make first of CZ, the second binding post forms the 220V ac circuit, even resistance wire stone or metal plate for standing a stove on as a precaution against fire heating power is cooked, in the closed situation of 1KT1, if 2KT(the second energization delay relay) time-delay be 4 hours, then 2KT powered on after 4 hours, 2KT1 disconnected after 4 hours, 1KT is dead electricity after 4 hours then, and 1KT2 reverted to disconnection after 4 hours, and is final, stopped the power supply to the resistance wire stone or metal plate for standing a stove on as a precaution against fire after 4 hours, one hour is that energising is cooked the time therebetween.
The first gear of change over switch (being moving contact and the first closure of deciding contact) is the existing Artificial Control time mode of cooking.
This novel beneficial effect is:
1, circuit structure is simple, and cost of manufacture is low, only needs two energization delay relays and a change over switch, can realize with existing Three-hole socket combination.
2, in constantly automatically energising of regulation, auto-breaking behind the automatic cooked of setting-up time section, thus finish whole Automatic-cooking process.
Description of drawings
Fig. 1 is the circuit diagram of this regular socket.
Embodiment
Fig. 1 illustrates, a kind of electric rice cooker regular socket, comprise Three-hole socket CZ, 220V live wire L is connected to the moving contact of change over switch K, first of change over switch K decides the first binding post that contact a is connected to described Three-hole socket CZ, the second binding post of Three-hole socket CZ is connected to zero line N, second of change over switch K decides to be connected to zero line N after contact b is connected in series the normally closed interlock 2KT1 of the second time-delay relay 2KT and the first time-delay relay 1KT in turn, the first normally open contact 1,KT1 one of the first energization delay relay 1KT is terminated at the normally closed interlock 2KT1 of the second time-delay relay 2KT and the node of the first relay 1KT, after being connected in series the second time-delay relay 2KT, this first normally open contact 1KT1 other end is connected to zero line N, second of change over switch K decides to be connected to behind the second normally open contact 1KT2 that contact b is connected in series the first time-delay relay 1KT the first binding post of Three-hole socket CZ, the 3rd binding post ground connection of Three-hole socket.
Be connected with the indicator light LD that cooks between first, second binding post of described Three-hole socket CZ, HD is power supply indicator.
