Abstract

A house electrical heating plate of electricity-saving, comfortness and safety is provided. The utility model belongs to the technical field of household effects, which comprises an electrical heating plate, a manual switch and a time controller. Wherein, the time controller is composed of a relay and an electronic controller. A commercial electricity live wire of 220V is connected to a contact fixing end of the relay and a normally open contact of the relay and the commercial electricity zero line are lined with the electrical heating plate; a diode D1 for filtering is connected to one end of the relay winding in one aspect and achieves a stable voltage of 5V through a R2 and ZD constant voltage control circuit in another aspect, thus to provide working voltage for the electronic controller U. A pin 1 of the electronic controller U is connected with the toggle switch switching resistance R3 and R4 to form a single impulse electronic controller, thus to change the time through switching the R3 and R4. When the time set is near, audions T1 and T2 are in cut-off status and free of operation, the relay is turned off and the contact returns to the normally close status to switch off the electrical heating plate. The utility model, by adding the timing function on the electrical heating plate, has the advantages of simple structure, low price, easy fabrication and safe operation, etc.

Description

A kind of power saving, comfortable, safe family expenses electric mattress

Technical field:

The utility model belongs to the household implements technical field, is specifically related to the electric mattress of prescribing a time limit automatically of the power saving of a kind of energy, anti-fire, and international Patent classificating number is: A47G9/06.

Background technology:

Normally used electric mattress is made up of electric mattress and power switch, and power switch can divide high temperature shelves and low temperature shelves.This electric mattress is simple in structure, and is cheap, easily makes, but walks or an all overtime at every turn use forgets to turn off power supply as the people, can bring following problem: 1. electricity wasting; 2. high temperature causes the user to feel extremely uncomfortable; 3. surpass binding hours at every turn and use, can make the wire insulator accelerated ageing, when this aging value of reaching capacity, will cause the generation of fire.

Summary of the invention:

Goal of the invention of the present utility model is: a kind of power saving, the adjustable family expenses electric mattress of power-on time comfortable, that stop fire incident are provided.

The purpose of this utility model is achieved through the following technical solutions: the utility model is made up of electric mattress, hand switch and timing controller, described timing controller is made up of relay and electronic timer, its annexation is as follows: 220V civil power live wire is received the relay contact stiff end, and relay normally open gets an electric shock and the civil power zero line connects electric mattress.Full-wave rectification bridge B ac input end is through R1, the step-down of C1 parallel circuit, connect the 220V civil power, dc output end connects capacitor C 2, diode D1 carries out filtering, DC voltage is about 7.5V after the filtering, succeed an end of electrical equipment winding on the one hand, obtain the 5V burning voltage through R2, ZD mu balanced circuit on the other hand, for electronic timer U (CD4541) provides 5V operating voltage.The base stage of triode T1 is received 8 pins of electronic timer U through resistance R 7, grounded emitter, colelctor electrode one end is through the positive pole of receiving full-wave rectification bridge B of resistance R 8, the other end is received the base stage of triode T2, the grounded emitter of triode T2, colelctor electrode one end is received the positive pole of full-wave rectification bridge B through D2, and the other end is received on the relay; 12,13 pins of electronic timer U connect the 5V power supply, 5,7,9,10 pin ground connection, and 6 pin are through resistance R 6 ground connection, 3 pin connecting resistance R5,2 pins connect capacitor C 4,1 pins and meet toggle switch convert resistance R3, R4, form pulse formula electronic timer, can change timing by switching R3, R4; The 8 pins output high level formula T1 of electronic timer U, T2 work, thus relay is connected normally opened contact, the electric mattress energising.When timing then, the 8 pin output low levels of electronic timer U, triode T1, T2 do not work, and are in cut-off state, relay outage, normally closed position is recovered in the contact, the electric mattress outage;

The base stage of triode T1 is received 8 pins of electronic timer U through resistance R 7, grounded emitter, colelctor electrode one end is through the positive pole of receiving full-wave rectification bridge B of resistance R 8, the other end is received the base stage of triode T2, the grounded emitter of triode T2, colelctor electrode one end is received the positive pole of full-wave rectification bridge B through D2, and the other end is received on the relay;

The course of work of the present utility model is: relay often is coupled in the 220V civil power live wire, and relay adhesive or disconnection are controlled by electronic timer.When hand switch K was closed, electronic timer made the relay J closure, the electric mattress energising; When timing (for example 4.5 hours) then, electronic timer disconnects relay contact, the electric mattress outage, thereby reach safety, purpose of power saving.

Electric mattress regularly cuts off the power supply and can avoid because of forgetting that outage makes the overheated adverse consequences that produces of electric mattress, has also avoided not also power consumption and saved electric energy of time spent because regularly cut off the power supply simultaneously; Regularly outage makes the user can be because of the electric mattress long too hot and discomfort that produces of switching on.

The utility model makes electric mattress have the function of timing working, has the good effect of manufacturing simple in structure, cheap, easy, safety.
