Background technology

Existing electric cooker affairs that should be kept secret tool, be mostly utilize the formula of invading in the electric heating tube, outward twine the heating wire formula, cover electrothermal membrane type outward, the thermal efficiency is low, the electric cooker operation of cooking congee, the boiled back liquid spill of cooking congee often causes waste and is burned, the electromagnetic stove operation, the bottom is burnt sticks with paste, and liquid spill is even more serious, and electricity boils waist device, electric heater pot congee, Baoshang and all has the similar phenomenon that can not eliminate.

The invention provides a kind ofly brand-new cook congee, the manufacture method of Baoshang utensil, adopt the high-frequency electromagnetic heating, it is outer around high frequency coil heating, quick heating, efficient height to improve ferromagnetic material; If shielding water jacket and steam waste heat utilization jar make full use of the heater waste heat and accumulate, avoid liquid to overflow; Energy-saving and emission-reduction are to be widely used in making the cook congee power-economizing method of cooker of electricity.

Summary of the invention

By solenoid lower heating around interior pot, heat storage medium, shielding water jacket, UTILIZATION OF VESIDUAL HEAT IN water jacket pot cover, thermal insulation medium, shell, control circuit composition are established in interior pot outside.

1. solenoid is wrapped in spreading insulating barrier ferromagnet pipe outside, and the solenoid outside is established insulating barrier, water jacket, heat-insulation layer successively and constituted and add hot water tank, and water jacket is made with the metal material of maskable electromagnetic signal, guarantees shield electromagnetic interference.

2. pot cover is that steam waste heat utilizes jar, is made up of water receptacle, heat-insulation layer and cold water water injection valve, pot cover relief valve, pot cover drain valve etc., guarantees UTILIZATION OF VESIDUAL HEAT IN.

It is excessive to realize cooking congee, and Non-burnt pot, temperature retention time are long, and the thermal efficiency ratio electric cooker improves 20%, improves more than 10% than electromagnetic stove.

The specific embodiment

The present invention adopts the following specific embodiment:

1, parts are prefabricated:

Various parts connecting hole parameters are identical, and fastening bolt is identical, and earth stud adopts the brass material, and other fastening bolts adopt stainless steel, and parts connect sealing gasket and adopt the food grade encapsulant.

UTILIZATION OF VESIDUAL HEAT IN pot cover: toply be installed into spreading insulation material behind water management pipe valve, the pressure protection valve, can integral solder become water jacket, also can be connected with the upper cover body flange by lower cover.

Interior pot: interior pot diameter is 4: 6 with a pot height ratio.

The exhausted layer of spreading ferromagnet: adopt ferrimagnet, full circle post or assembly unit all can, highly equal 70% of boiled water tank height, internal diameter equals the boiled water tank external diameter, process can suit deviation, twine solenoid after outside ferromagnet, placing inner insulating layer, with the external insulation layer protection, the lead-out wire location is drawn, form calandria, calandria be interior pot high 40%.

The shielding action water jacket: the height less than the boiling water pipe valve to boiled water tank size suitable for reading, weld the pipeline section that is communicated with boiled water tank in the water jacket outer lower portion, the water jacket internal diameter can be sleeved on to form and be machining deviation on the calandria external diameter, and shielding action water jacket and interior pot top closely cooperate, and play shielding action.

2, parts assembling

After various valves in inside and parts installation, the sealing gasket fitted bolt is fastening between each pre-constructed unit.

Various outside pipe valves are installed according to general valve installation method.

According to the general purpose control principle, manufacturing control system is settled warm keeping element and temp-controlling element on calandria top.

Stewing down seals with other potted component of general food-grade between the body component, places liquid and infiltrates the contact slit.

The insulation material closed processes.

Pot cover can adopt general electric cooker connected mode with the body component of stewing down, also can adopt independent placement.

3, operation principle

Water in the pot cover can carry out the cold water input by pot cover water intaking valve, pot cover drain valve, and hot water output replenishes the water that interior pot needs by steam pressure release valve, is heated when producing too high pressure at pot cover, and too high pressure is discharged by the pot cover relief valve; The water filling of shielding action water jacket open-type, pipe valve output warm water.

Electronic control circuit adopts general boiling water control circuit, carries out programme-control according to above-mentioned steps.

Control system comprises high-frequency conversion circuit, power output adjustment circuit, power (state) display circuit and safety protective circuit.The effect of high-frequency conversion circuit is to convert the direct current that rectification circuit is exported to high frequency electric, the supply high frequency load coil.Different food has different culinary art requirements, the promptly different duration and degree of heating, and this adjusts circuit by power output can change the size of power output, and demonstrates on power (state) display.Safety protective circuit has load detection device, prevents part electro-heat equipment, overtemperature protection system, safety locking motion.
