Description

A kind of electric blanket

Technical field:

The utility model relates to the improvement of electric blanket.

Background technology:

The electric blanket of selling on the market has only a controller to control the switching of the height and the power supply of electric blanket temperature now, does not have the height and the timing function of design temperature accurately.When the temperature of electric blanket is too high, can not cut off the power supply automatically, be unfavorable for saving electric energy, the easier people of making feels mouth parched and tongue scorched in use or serious fire incident takes place.

The utility model content:

The utility model is exactly at the problems referred to above, and the electric blanket of a kind of may command heating time and temperature is provided.

The utility model adopts following technical scheme, the utility model comprises electric blanket, power line, attaching plug, controller, its structural feature controller outside has temperature adjusting key, time-controllable key, on ﹠ off switch, power supply indicator, adopts the Circuits System of being made up of temperature-control circuit, detection power-down circuit, timing controller in the controller; Described temperature-control circuit adopts adjustable resistance and is connected in series, described detection power-down circuit adopts solid-state relay with being connected in series, integrated temperature sensor is arranged on a side of electromagnetism heating controller, by linking to each other with solid-state relay, timing controller links to each other with the electromagnetism heating controller by lead.

The beneficial effects of the utility model:

1. can set heating time as required:

Owing in the controller internal circuit of the present utility model timing controller is arranged, the user can set heating time as required, can save electric energy, avoid simultaneously because carelessness or fall asleep and forget that the powered-down switch causes the danger of user's mouth parched and tongue scorched or initiation fire;

2. can set heating-up temperature as required:

The user can regulate the temperature height according to self hobby.Owing in the controller internal circuit of the present utility model integrated temperature sensor, solid-state relay are arranged, when temperature surpassed limiting temperature, the generation of fire incident avoided dump by solid-state relay;

3. simple in structure:

Components and parts in the utility model circuit all can be purchased from market, are easy to make, and are easy to popularize.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the circuit diagram of the utility model controller.

Embodiment:

The utility model comprises electric blanket 8, power line 7, attaching plug 1, controller 5, controller 5 outsides have temperature adjusting key 6, time-controllable key 4, on ﹠ off switch 3, power supply indicator 2, adopt the Circuits System of being made up of temperature-control circuit, detection power-down circuit, timing controller in the controller 5; Described temperature-control circuit adopts adjustable resistance Rp and voltage comparator AD311 to be connected in series, described detection power-down circuit adopts solid-state relay SSR to be connected in series with electromagnetism heating controller EH, integrated temperature sensor AD590 is arranged on the side of electromagnetism heating controller EH, link to each other with solid-state relay SSR by voltage comparator AD311, timing controller KG316T links to each other with electromagnetism heating controller EH by lead.

Integrated temperature sensor AD590, timing controller KG316T, solid-state relay SSR, electromagnetism heating controller EH, voltage comparator AD311 all can purchase from market.

Below in conjunction with a description of drawings course of action of the present utility model:

Attaching plug 1 of the present utility model is inserted the 220V power supply, open on ﹠ off switch 3, this moment, power supply indicator 2 was bright.Regulate time-controllable key 4, by the switching time of the timing controller KG316T configuration switch in the circuit; After setting turn-on time, regulate temperature adjusting key 6, the temperature signal that solid-state relay SSR senses because of integrated temperature sensor AD590 is less than the temperature of setting, and solid-state relay SSR connects electromagnetism heating controller EH, electromagnetism heating controller EH in the circuit begins heating, and temperature rises; When the temperature that senses as integrated temperature sensor AD590 reached design temperature, solid-state relay SSR disconnected, and electromagnetism heating controller EH disconnects simultaneously, stopped heating.When the time that timing controller KG316T sets arrived, electric blanket 8 also stopped heating.

Electric current in the power supply makes alternating current become galvanic current by transformer T, pressurizer 7812.
