Abstract

The utility model relates to a heat storage electric iron which is composed of an iron body and an opening and closed type shelf. The heat storage electric iron is characterized in the technique that the molten salt substance composed of lithium nitrate and potassium nitrate (or sodium nitrate) is encapsulated in an interlayer of a bottom board of the electric iron. Electrically exothermic material is arranged on the bottom board. Electrically exothermic material is lined with an insulating layer at the top and the bottom. A temperature control device is arranged on the tail section of the electric iron. The point of control temperature for the temperature control device is 5DEG C higher than the melting point for the molten salt substance. Two electrodes are arranged on the facade of the tail section of the electric iron, protruding out of the insulating plate and bulging outwards. An insulating loose plate is arranged on the upper part of the on-and-off shelf. Two holes slightly bigger than the electrodes on the iron body are arranged in the loose plate. The centre distance between the two holes is equal to the center distance between the two electrodes. Two electrodes connected with the electric power source are arranged on the bottom plate of the shelf corresponding to the two holes in the insulating loose plate. Disengaged from the shelf, the electric iron can maintain the stable operating temperature without reduction for a certain period of time so as to realize the purposes of safety and convenience.

Description

Heat storage electric iron

The utility model relates to a kind of heat accumulation electric iron, comprises flatiron body and switching regulator shelf.

At present, known electric iron is the traction power line, and inconvenient operation is also dangerous.Chinese patent notification number CN2071663U proposes a kind of wireless energy-conservation electric iron, and electric iron body and base two are partly formed, and flatiron can separate with base when flatiron, so reach safety, convenient, aim of power saving.But owing to do not have heat-retaining mass in the electric iron, thus after flatiron leaves base disengaging power supply, the very fast decline of temperature, the time of keeping operating temperature is very short.

The purpose of this utility model provides a kind of heat accumulation electric iron, can keep operating temperature within a certain period of time when making electric iron break away from power supply.

The purpose of this utility model realizes like this: the fused salt material that encapsulation is made up of lithium nitrate and potassium nitrate in the base plate interlayer of electric iron, the fusing point of this fused salt material (melting range) is pressed the different proportionings of lithium nitrate and potassium nitrate, can regulate according to designing requirement, can satisfy the operating temperature (200-230 ℃) of electric iron fully.The compounding substances that lithium nitrate and potassium nitrate are formed is a chemical industry salt bath material commonly used, and it is good to have chemical stability, does not fire, no flash-point, and characteristics such as non-corrosiveness can be used in 200～500 ℃ temperature range.Electric heating material is installed on base plate again, and electric heating material is lined with insulating barrier up and down.In addition, at indicator lamp of the anterior installation of electric iron, attemperating unit is equipped with in the position near electrode in the afterbody, and the control point of attemperating unit is greater than 5 ℃ of fused salt melting point substances.Two electrodes of electric iron are installed in the positive back of afterbody, pass outwards outstanding 1 centimetre of insulation board.One switching regulator shelf is set in addition again, the insulation trap is equipped with on switching regulator shelf top, two holes more bigger than electrode are arranged on the trap, its spacing can make two electrodes enter in the hole simultaneously, mounting spring under the trap, two electrodes that link to each other with power supply are arranged on the shelf base plate, and its spacing and electric iron afterbody two electrode spacings are together.During Ironing, electric iron is placed on the shelf, because self gravitation, two holes that compression spring, electric iron afterbody electrode pass the insulation trap contact with shelf bottom two electrodes, connect power supply, and indicator lamp is bright, the electric iron heating.When temperature rises to fused salt melting point substance (electric iron design work temperature), the fusing of fused salt material, temperature no longer rises, flatiron begins heat accumulation, finishes when the fused salt material all melts, and the electric iron temperature continues to rise, reach when being higher than 5 ℃ of operating temperatures, attemperating unit is cut off the electricity supply, and indicator lamp goes out.Electric iron is taken when the shelf Ironing,, can be kept operating temperature not descend within a certain period of time because inside contains heat.During the arrangement object to be ironed, electric iron can be placed heat accumulation on the shelf.Ironing is the process of discontinuity, and according to observations, the time of one-time continuous flatiron seldom surpasses 2 minutes, and this product design is temperature retention time 3 minutes, can satisfy the needs of practical application.Temperature retention time is by the encapsulation amount decision of fused salt material.The also available sodium nitrate of above-mentioned potassium nitrate substitutes.

The utility model is owing to be packaged with heat-retaining mass, can keep operating temperature so electric iron breaks away from behind the power supply in a period of time, thus can make things convenient for, safe, work effectively.

Below in conjunction with diagram, performance of the present utility model is described:

Fig. 1 is the fused salt material 2 that encapsulation is made up of lithium nitrate and potassium nitrate (or sodium nitrate) in flatiron body, the base plate 1, it on the base plate insulating barrier 3, the centre is an electric heating material 4, attemperating unit 5 is installed near in the shell of afterbody, totally two of electrode 6(, only draw one) be installed on the positive back of afterbody, and 1 centimetre of outstanding insulation board.Indicator lamp 7 is contained in the flatiron stem, and 8 is handle.

Fig. 2 is the switching regulator shelf, on the insulation trap 9 two holes 10 are arranged, hole 10 is more bigger than the electrode on the flatiron body 6, two hole centre-to-centre spacing are identical with two electrode centers distance, trap 9 usefulness springs 11 link to each other with the shelf base plate, two electrodes 12 be connected with external power are installed on the shelf base plate, and its centre-to-centre spacing is identical with two electrodes 6 on the flatiron body.
