IPC: DBG 75/08

Electric iron

Technical field

The utility model relates to household electrical appliances, in particular to electric irons.

State of the art

A known electric iron containing a metallic sole, a heating element, a casing, a handle and a temperature controller, as well as a vertical position switch, a device that fixes the movable contact of the temperature controller in the open state, and a locking mechanism consisting of a lever, two pushers and a spring. (see the description of the invention to the copyright certificate No. 235858, IPC: DOBR 75/08)

Also known is an electric iron containing a metal sole, a heating element closed by a casing, and a handle, and a time relay is additionally introduced into it, the contacts of which are connected in series with the heating element and the network, and the movable and fixed parts of the handle are connected by means of a squeezing spring, while the movable part of the handle is equipped with a lever that interacts with the means for activating the time relay. (See the description of the invention to the copyright certificate No. 1276701, IPC: D06R75 / 08).

The disadvantages of the above technical solutions is the use of mechanical lever systems for closing and opening of electrical contacts.

The essence of the noble model

The creation of a utility model is based on the task of developing an electric iron design that provides increased reliability through the use of a modern electronic circuit for controlling the power supply of the iron, as well as fire safety

use of an electric iron due to the fact that the response time of the time relay is selected less than the time at which a fire occurs.

This object is achieved by the fact that in a known electric iron containing a metal sole, a heating element, a timer, a casing and a handle, a photocell located at the top of the handle of the iron at the point of contact with the human hand is additionally introduced.

The presence of the photocell contributes to the most compact design solution of the handle of an electric iron, increases the reliability of its operation through the use of an electronic circuit and ensures fire safety when the power is turned on.

Information confirming the feasibility of implementing a utility model

The electric iron contains a metal sole 1, a heating element closed by a casing 2, a time relay 3, the contacts of which are connected in series with the heating element and the network, as well as a handle 4, inside which a photocell 5 is installed at the point of contact with the human hand, with an electronic control circuit .

The device operates as follows.

The iron power cord is plugged into an electrical outlet. When taking the iron for a short time (1-2 seconds) by the handle 4, the luminous flux to the photocell 5 is blocked, the electronic control circuit is activated and the heating element of the iron is turned on to the temperature set by the thermostat. In the process of ironing, the photocell 5 is constantly closed by hand and the heating temperature is automatically maintained by the thermostat. If you need to temporarily stop ironing

.

the hand is removed from the handle 4, the photocell 5 is triggered and after a period of time specified in the time relay, the power supply to the iron is disconnected. The response time of the time relay is selected less than the time at which the fire occurs, which ensures fire safety.

To continue ironing, to re-turn on the electric heating element of the iron, the process is repeated.

In the case of termination of ironing, the hand is removed from the handle of the iron and the power cord is disconnected from the outlet.

Currently, a working model of the iron is made.
