Abstract

The utility model discloses a multi-purpose simple electric cooker, in which two stainless steel electrodes are fixed in a ceramic utensil to be used as heating components. The ceramic utensil holds water. When the stainless steel electrodes contacts the power supply, the water can conduct to heat the water and make the water boil, and the generated vapor can steam the rice which is held in an aluminium basin. The heating components are arranged under the cooker, which is connected with a power plug arranged on the wall of the cooker by a conductor. The cooker body is shaped by pressing a thin steel plate, the inner and outer sides of the cooker are paint with high temperature resistant paint, and the inner and outer sides of the wall and the cover of the cooker are paint with porcelain enamel. The utility model can be used as an electric cooker, a steam cooker, a pressure cooker, and a common rice cooker. When used as a pressure cooker, the multi-purpose simple electrical cooker needs a clamp to be arranged on the cover of the cooker. When used as a common rice cooker, the multi-purpose simple electrical cooker only needs not to use the heating components.

Description

Multi-purpose simple electrical cooker

The utility model is a kind of simple and easy multipurpose electric rice cooker, belongs to household electrical appliance.

Existing electric rice cooker is to make heater with resistive element, with magnetic and temperature-sensitive element control heating process, realizes heating, insulation and power down function.The utility model characteristics different with existing electric rice cooker are: utilize two naked metal electrodes under water, electric energy be converted into heat energy by the water conduction, and with this as heating element.Through evidence, before the water boiling, heater element power raises with temperature and increases.When continuing heating, water keeps boiling, and power reduces gradually.When the water evaporation is done, because of there not being conducting medium outage automatically between electrode.Like this, the utility model need not add any control element, can realize heating, insulation and automatic circuit break function.

Water conduction and the mechanism that heats up are: the salt impurity disassociation in the water forms positive and negative ion, has the hydrone of polarity to be enclosed in around the ion, forms hydrated ion.Electrode under water forms alternating electric field at two interpolars under the alternating voltage effect.Positive and negative hydrated ion does relatively reciprocating motion under action of alternative electric field, and with hydrone collision, kinetic energy is passed to hydrone, its macro manifestations promptly is that electric energy is converted into heat energy water is heated up.

A kind of experimental provision of answering water conduction intensification mechanism to make introduced in " direct-heating type electric heater's making " literary composition of " household electrical appliance " in 1982 third phase publication.

The purpose of this utility model is: for the domestic consumer provides inexpensive, durable, and have multi-purpose household electrical appliance such as electric rice cooker, steamer, pressure cooker.

Content of the present utility model, shown in Figure of description 1, a pot body (1) and a pot cover (5) with insulation property; Pot mouthful diameter is between 200～350 millimeters.Pot body (1) and pot cover (5) joint have a rubber seal (4); Be provided with heating component in pot body (1) bottom, it is to be fixed in the water dish (12) that insulating material makes by two naked metal electrodes (11) to constitute.Electrode (11) by lead (10) be fixed on a pot body (1) on supply socket (8) in power plug (9) be connected; The steamed rice basin (2) that top has logical steam vent (20) is supported on pot body (1) by sealing ring (4); The additional clamping device of one cover is arranged, form by compacting ring (13), draw ring (15), eccentric clamp (16) and clamp seat (14).Its effect is that pot cover (5) is pressed on pot body (1); The exhaust steam valve that flame arrester vent plug (6) is housed on pot cover and forms by valve gap (17), valve body (18), nut (19) and rubber blanket.Its effect is the control pot inner pressure.Fig. 1 represents that a pot body (1) and pot cover (5) are to make with steel plate, and surperficial enamel coating can be worked as a kind of version that electric rice pressure cooker is used.Fig. 2 is that the K of Fig. 1 is to view.Fig. 3 is that the W of Fig. 1 is to zoomed-in view.

The utility model has been compared following advantage with existing electric rice cooker:

1. simple in structure, multiple functional.The heating element that has only two naked metal electrodes to form has heating, insulation and automatic circuit break function.

2. serve many purposes.Can make electric rice cooker, steamer and pressure cooker uses.

3. because of simple in structure, cost and price can reduce significantly.

4. the variation of heating process power is roughly the same with the trend of the required thermal change of process of cooking, and can save power consumption.

5. heating element is not fragile, even damage, repairs easily yet and changes.

6. the steamed rice basin is because of the distortion of colliding with, or the bottom is stained with foreign matter, can not influence described electric rice cooker operate as normal.

7. described electric rice cooker in no instance can be burnt meal.Even forget for a long time and cut off the electricity supply that heating element can not damage yet, do not waste electric energy yet.

Realize that best way of the present utility model is the product of making shown in Figure of description 1.
