Abstract
A timer for microwave oven is composed of time switch K1, power switch K2, roasting switch K3 and roasting circuit, and features that two contacts of power switch K2 and roasting switch K3 are serially connected to roasting circuit and another contact is directly connected to microwave circuit. The barbecue circuit is connected with the microwave circuit in parallel, and the power conversion switch K2 is a two-way switch. The time switch K1 is connected with a contact of the power conversion switch K2, and the time switch K1 is closed for timing. One end of the motor is connected in parallel between the time switch K1 and the power change-over switch K2. The utility model relates to an ingenious, configuration optimization, reliability are high, control is simple, the cost is lower, convenient and practical, and its control terminal is less, can ensure that microwave oven's performance is good.
Description
Technical field
The utility model relates to a kind of micro-wave oven, specifically is the timer of micro-wave oven.
Background technology
The existing timer that is used for micro-wave oven, as disclosed a kind of micro-wave oven timer in the Chinese patent application number 00241879.7, it is characterized in that on existing timer switch circuit, removing relay switch, on the microswitch K4 of timer switch circuit, increase a terminal, make microswitch K4 change into normal open and close type microswitch by open in usual; On reed switch K2, increase a terminal, make reed switch K2 change into two-way switch by one-way switch.It is said that this design both can satisfy the timing controlled requirement of microwave, barbecue dual-purpose stove fully, and simplified the on-off circuit of micro-wave oven timer, make it more reasonable, improved the reliability of complete machine, reduced the manufacturing cost of micro-wave oven again.But it is more that the shortcoming of its existence is a control terminal, and control is complicated, and cost is higher, and the fault rate in the use is also higher, thereby directly influence the reliability that the micro-wave oven complete machine uses, and is necessary further improvement and perfect.
The utility model content
The purpose of this utility model aims to provide that a kind of control terminal is less, structure optimization, control is simple, cost is lower, dependability is high micro-wave oven timer, to overcome weak point of the prior art.
Press the timer of a kind of micro-wave oven of this purpose design, comprise clock switch K1, power change switch K2, barbecue K switch 3 and the barbecue circuit of serial connection successively, two contacts that it is characterized in that power change switch K2 are serially connected on the barbecue circuit with barbecue K switch 3, and another contact of power change switch K2 directly is connected on the microwave circuit.
Described barbecue circuit is in parallel with microwave circuit, and power change switch K2 is a two-way switch.
The end of described clock switch K1 is connected with power change switch K2 one contact, and clock switch K1 closure is a time action.Motor one end is attempted by between clock switch K1 and the power change switch K2.
The utility model design is ingenious, structure optimization, reliability height, control is simple, cost is lower, convenient and practical, and its control terminal is less, can guarantee the use of microwave ovens function admirable.
Description of drawings
Fig. 1 is the utility model one embodiment circuit theory diagrams.
Fig. 2 is the circuit theory diagrams when using the microwave state.
Fig. 3 is the circuit theory diagrams when using barbecue or admixture.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the timer of this micro-wave oven comprises clock switch K1, power change switch K2, barbecue K switch 3 and binding post thereof, clock switch K1 one end is connected with power change switch K2 contact 6, power change switch K2 two contacts 6,7 and barbecue K switch 3 are serially connected on the barbecue circuit, and the contact 6,8 of power change switch K2 directly is connected on the microwave circuit.
Referring to Fig. 2, when using the fiery status function of microwave height, clock switch K1 closure is as time action, and barbecue K switch 3 disconnects always, and power change switch K2 contact 6,8 closures directly are connected on microwave circuit, reaches and satisfies the high fiery status function of microwave;
Use the low fire of microwave, in when low fire, moderate heat, the fiery state of middle height, clock switch K1 closure is as time action, barbecue K switch 3 disconnects always, power change switch K2 contact 6,8 or 6,7 according to the low fire of microwave, in the time scale that requires respectively of low fire, moderate heat, the fiery state of middle high closure successively, when being contact 6,8 closures, be exactly that contact 6,7 disconnects.
Referring to Fig. 3, when using the barbecue state, clock switch K1 closure is roasted K switch 3 closures as time action, and power change switch K2 contact 6,7 closures directly are connected on the barbecue circuit, reaches and satisfies the barbecue status function;
When using microwave/barbecue admixture, clock switch K1 closure is as time action, barbecue K switch 3 closures, and power change switch K2 contact 6,7 or contact 6,8 require closure successively according to the time scale of admixture, reach and satisfy the admixture function.
