Description

Numeral is controlled electric stove regularly

The utility model belongs to the electric stove technical field, and particularly a kind of numeral is controlled electric stove regularly.

Controlled electric stove on the existing market is the electric stove of mechanical timer, electronics knob timer or relay power governor formula.Their common shortcomings that exists are poor reliability, and error is big, and timing is not directly perceived, and the double plate electric stove need be adorned two timers.

The purpose of this utility model is to develop regularly controlled electric stove of a kind of new Digital at the shortcoming of existing product existence.This electric stove has regularly accurately, and error is little, and intuitive display is easy and simple to handle, and the buzzer prompting is arranged, but many advantages such as power stepless continuous adjusting.

This numeral regularly feature of controlled electric stove is that it is made of electric stove and digital timing controller two parts, the numeral timing controller is made up of digital timing trigger circuit and digital display control device two parts, the numeral timing trigger circuit is made up of adjustable capacitance-resistance circuits for triggering of bidirectional triode thyristor and digital timing circuit, the numeral timing trigger circuit is contained on the interior circuit board of digital display control device, and digital timing controller links to each other with electric stove by lead.Electric stove is the cooker that the energy is made in electricity consumption, and its purposes and structure are prior art, no longer here stating more.The numeral timing controller is to have the regularly electric stove control device of Presentation Function of numeral, and it is made up of digital timing trigger circuit and digital display control device two parts.The numeral timing trigger circuit is a circuit of finishing digital Displaying timer and triggering control electric stove.The numeral timing trigger circuit constitutes by digital timing circuit with the capacitance-resistance circuits for triggering that controllable silicon is formed.Digital timing circuit is electronic digital circuit, it is to control the circuit that cuts off the power supply when electric stove regularly is energized to, regularly length is shown by nixie display, regulate with the plus-minus button in the use, nixie display, plus-minus button and relay are packed on the digital display control device, and digital timing circuit, bidirectional triode thyristor is adjustable capacitance-resistance circuits for triggering and other control circuit all are contained on the circuit board of digital display control device.Bidirectional triode thyristor is adjustable, and the capacitance-resistance circuits for triggering are circuit of regulating electric stove watt level, control electric stove temperature, and it triggers with controllable silicon, regulates with adjustable resistor, regulates with the power adjusting knob in the use.The power adjusting knob is contained on the housing of digital display control device.The digital display control device is the parts that install and fix electric elements such as various control buttons, knob, potentiometer, nixie display, supply socket, buzzer, power meter, power supply indicator, overload protective device, circuit board, and these electric elements all are packed on the housing.Be measure against electrical leakage and short circuit, on the digital display control device, also be provided with electric leakage, short-circuit protector.Numeral regularly shows and controllable silicon capacitance-resistance circuits for triggering technology is a core of the present utility model, and it can be suitable for using on the various electric stoves.As with the electric stove of gas range, simple eye electric stove or many electric stoves etc.

This electric stove has electric stove now relatively, and it has regularly accurately, intuitive display, and reliable trigger has the buzzer prompting, but the adjusting of power stepless continuous, and have advantages such as memory function, easy to use, handling safety.

Accompanying drawing 1 is regularly embodiment master's TV structure schematic diagram of controlled electric stove of the utility model numeral.

Accompanying drawing 2 is the utility model numeral timing controller fundamental diagram.

Among Fig. 1: 1. housing, it is the housing of digital timing controller, also is the device that installs each control assembly and circuit board; 2. supply hub, it has two electric stove supply hubs, and other establishes the standby jack of two three holes and diplopore; 3. earth leakage protective device; 4. circuit board, digital timing trigger circuit is packed on this circuit board; 5. timing circuit switch is mainly protection timing part and circuit and establishes; 6. regularly regulate knob, it has two, an increase, a minimizing; 7. electric stove, it is provided with two stone or metal plate for standing a stove on as a precaution against fires, and one of them stone or metal plate for standing a stove on as a precaution against fire is recessed dish, is used for the sunken bottom pot, and another stone or metal plate for standing a stove on as a precaution against fire is the square position, is used for pan; 8. change-over switch, it controls the switch of conversion to two stone or metal plate for standing a stove on as a precaution against fires about on the electric stove (7), because a digital timing controller can only carry out digital display regularly to a stone or metal plate for standing a stove on as a precaution against fire, can not carry out digital display regularly to two stone or metal plate for standing a stove on as a precaution against fires simultaneously; 9. the power adjusting knob is used to regulate the stone or metal plate for standing a stove on as a precaution against fire temperature; 10. indicator lamp, it is the indicator of digital timing trigger circuit duty; 11. voltmeter, magnitude of voltage when it can directly show this stone or metal plate for standing a stove on as a precaution against fire work; 12. power lead is connected with plug above it, it is the power line of electric stove, directly is inserted in the use on the supply hub (2); 13. radiator, owing to adopt controllable silicon in the digital timing trigger circuit, it can produce heat at work and need dispel the heat, and radiator is realized with aluminium section bar; 14. buzzer plays indication user effect, after timing arrives, then indicates user's timing to arrive, controller will cut out the power supply of controlled stone or metal plate for standing a stove on as a precaution against fire automatically.

Fig. 3 is the embodiment circuit diagram of the utility model digital timing circuits for triggering. Its operation principle as shown in Figure 3.

Fig. 4 is the example structure schematic diagram of digital timing display unit.
