Abstract

The utility model relates to a timed temperature-regulation socket, belonging to electric appliances. A group of relay normally opened contacts are connected in series between the fire wire plug electrodes of the socket and fire wire socket electrodes. An electronic clock with electric connection, a delaying circuit, a multivibrator, a relay executive circuit and a stabilized D. C. source are arranged in the socket. A function conversion switch is connected between the delaying circuit and the working power supply of the multivibrator. The novel socket has the functions of precision timing, switching on, switching off, and temperature adjustment for electric equipment. The utility model which is widely suitable for electric equipment, such as electric cookers, etc. has the advantages of convenient utilization, electric energy saving, and extension of the service life of the electric equipment.

Description

The timing temperature regulating socket

Regularly temperature regulating socket belongs to electric equipment products.

The current supply socket of generally using all is direct energized generally, and promptly plug connects power supply, and jack connects consumer.Also have on socket, to be provided with hand switch control socket and electricity to be arranged or do not have electricity, but all can not regulate the consumer working condition.

The objective of the invention is: provide a kind of can make socket on demand setting-up time regularly switch on, cut off the power supply and adjust the novel socket of consumer temperature (power).

Technical scheme of the present invention is: be connected in series a group relay normally opened contact between the live wire plug electrode of socket and firewire jack electrode, the electronic clock circuit, delay circuit, multivibrator circuit, relay executive circuit and the D.C. regulated power supply that electrically connect are housed in the socket.The external driving amplifying circuit of electronic clock circuit connects with the delay circuit input end, and its output terminal connects relay coil through switching tube, and the pilot relay action realizes regularly energising outage.The multivibrator output terminal connects relay coil through same switching tube.The electronic clock circuit input end is three and adjusts button.Linkage function switch between delay circuit and the multivibrator working power.Electronic clock LCDs on the socket is the state transformation key by operating three adjustment buttons; Second, divide, the time numerical key; Second, to divide, in time, can show the time or set conduction time and fixed timing mark on demand during the flicker key.When socket need be operated in regularly energising, power down function, functional switch is turned to regularly, operate three adjustment key assignments conduction times, X branch during X for example, and on display screen, demonstrate the fixed timing mark symbol.Be inserted in unmanned operation on the scene of the time that just can be implemented on the socket with consumer and get final product work this moment.Electronic clock circuit timing controlled output terminal is low level signal at ordinary times, and the time of setting, signal was kept one minute to becoming high level, and this signal drives actuating of relay realization energising through amplifying.The length that needs conduction time is by the adjustment of time-delay knob, reference time delay 5～50 minutes.If the translation function switch was put temperature adjustment when socket need be operated in temperature adjustment function, utilize the thermal inertia of consumer work, change socket energising, power off periods and duty by thermoregulation knob and recently regulate average power realization temperature adjustment.The setting range of consumer power is 10%～90%.

The present invention has regularly energising, power down function and adjusting consumer temperature (power) function accurately.Easy to use, saves energy prolongs consumer serviceable life.Be widely used in consumers such as electric-heating cooking utensil.
