Description

Automatic cooking and slow cooking function electric cooker

The utility model relates to a household appliance, in particular to an electric cooker with an automatic quick-cooking and slow-cooking function.

At present, most of the electric cookers on the market are indirect heating mechanical temperature control electric cookers (developed and marketed by Datong Company and Toshiba Technology in Japan in 1960). After the main switch is turned on and the power is turned on, the electric heater in the electric cooker continues. Heating at a rated power until the outer pot water is evaporated to dryness. However, during the boiling of the outer pot until the outer pot water is evaporated, the large amount of heat generated by the electric heater will cause the water to evaporate quickly. Therefore, if the user When you want to simmer or simmer food, you often need to repeat the water addition after the water is evaporated. It is not only convenient to use, but also has the problem of unnecessary energy.

Therefore, the purpose of the present invention is to provide an electric cooker with an automatic quick-cooking slow-cooking function.

Therefore, the novel automatic cooking and slow-cooking electric cooker comprises a body and a electric cooker control circuit.

The body comprises an outer pot, an inner pot disposed inside the outer pot, and a metal heat conducting disc disposed outside the bottom of the outer pot.

The electric cooker control circuit comprises a high power quick cooker module, a medium power slow cooker module, and a temperature control switch.

The high-power quick-cooking module is disposed on the metal thermal pad and electrically connected to a power source to provide the body heating power when turned on.

The medium power slow cooker module is disposed on the metal heat conducting plate and electrically connected to the power source to provide heating power lower than the high power quick cooking module when the body is turned on.

The temperature control switch is electrically connected to the high-power quick-cooking module and the medium-power slow-cooking module, and when the sensed temperature is not higher than a predetermined value, the high-power fast-cooking module is turned on to provide heating power. When the sensed temperature is higher than a predetermined value, the switching makes the high-power quick-cooking module non-conductive, and the medium-power slow-cooking module is turned on.

The utility model has the advantages that: by setting the high-power quick-cooking module, the medium-power slow-cooking module, and automatically switching according to the sensed temperature through the temperature control switch, not only the slow stewing and the simmering method can be achieved.

In the embodiment, the heat insulating switch 44 is a manual rocking plate heat insulating switch, because the low power heat insulating heating module The operation of 4 is familiar to the industry and will not be described here.

The main switch 5 is electrically connected between the power source 9 and the temperature control switch 6, and is turned on by a user. When the main switch 5 is not turned on, the high-power quick-cooking module 2 and the medium-power slow-cooking module 3 is not turned on, the main switch 5 is switched to non-conduct when the temperature is greater than a working temperature. In the embodiment, the main switch 5 is a manual reset type temperature control off, and the working temperature is set to about 200 ° C, After the outer pot 12 is boiled, the power supply 9 is automatically cut off.

The temperature control switch 6 is disposed on the outer side of the outer pot 12 and near the bottom for sensing the temperature of the outer pot 12, and electrically connecting the high-power quick-cooking module 2 and the medium-power slow-cooking module 3 to When the sensed temperature is not higher than a predetermined value, the temperature control switch 6 is turned on, so that the high power quick cooker module 2 and the medium power slow cooker module 3 are both turned on to jointly provide heating power at the sensed temperature.

When the user wants to use the electric cooker of the embodiment to cook rice and food, it is necessary to add an appropriate amount of water to the outer pot 12, and place white rice, food and an appropriate amount of water inside the inner pot 14, and then operate the main The switch 5 is turned on. Since the temperature control switch 6 is normally closed, the high-power quick-cooking module 2 and the medium-power slow-feeding module 3 are simultaneously turned on to provide heating power (760W+200W=960W). Quickly heating the boiled water. When the outer pot 12 is rolled away, the temperature sensed by the temperature control switch 6 will be higher than 98 ° C. In order to switch the non-conduction, the high-power quick-cooking module 2 is not turned on and the heating power is stopped. At this time, the medium-power slow-cooking module 3 continuously supplies heating power (200 W) for heating.

Since the water and the food in the inner pot 14 have generally reached about 95 ° C after the outer pot is rolled, it is only necessary to input low-power (200 W) heat energy through the medium-power slow cooker module 3, The water of the outer pot 12 can be slowly evaporated to exchange heat between the heat and the bottom of the inner pot 14 to the food in the inner pot 14, and the temperature of the outer pot 12 can be maintained and raised to continue stewing. The food in the inner pot 14 can quickly evaporate the water by continuously providing high-power heat energy in the prior art. This embodiment can achieve the effect of cooking food by slow stewing and simmering, and can also reduce unnecessary Energy consumption.

When the water of the outer pot 12 is evaporated, the heating power (200w) provided by the medium power slow cooker module 3 will heat the bottom of the outer pot 12 to raise the temperature of the bottom of the outer pot 12 rapidly. When the operating temperature is greater than the set operating temperature (200 ° C), the main switch 5 is switched to be non-conducting to cut off the power supply 9, or is switched to the thermal insulation with the low-power thermal insulation heating module 4, at which time the temperature of the outer pot 12 will be Drop to about 85 ° C, so that the temperature control switch 6 returns to normally closed conduction, in preparation for the next operation.

Through the above description, the advantages of this embodiment can be summarized as follows:

By setting the high-power quick-cooking module 2, the medium-power slow-cooking module 3, and automatically sensing the temperature through the temperature control switch 6, the effect of cooking food by slow stewing and simmering can be achieved. And because the slow cooker only needs about 20% of the power to maintain the temperature when cooking, so the more Difficult to cook, the longer the food must be stewed, the higher the energy saved. Compared with the traditional electric cooker of the prior art, the stew can be used for 1 hour, energy saving can be more than 40%, stewing for 2 hours, about More than 60% energy saving, stewing for 3 hours, about 70% energy saving, it can be seen that its energy saving rate is as high as 40~70%, so it can save energy consumption and meet the trend of energy saving and carbon reduction. If the whole Taiwan 7.4 million electric cookers can be comprehensive Replacing this new type of electric cooker, the annual power savings can reach hundreds of millions of degrees, which is considerable.

Further, for the user, when stewing the food that is not easy to be boiled, it is only necessary to add water once in the outer pot 12 to cook for several hours, and can control according to the amount of water added to the outer pot 12. The length of the slow stewing time does not require the need to wait for the water to be repeatedly added to the electric cooker and repeatedly start the electric cooker as in the conventional technology. The use is simple and convenient, and the use convenience is greatly increased.

The application of the embodiment does not need to change the user's operating habits and methods, and only needs to add water to the outer pot 12 as in the conventional electric pot, and activates the main switch 5. The slow stewing function of the embodiment automatically switches. And it has a large energy-saving efficiency. If it is used together with a specially designed scale and time-converted measuring cup, it can greatly increase the convenience of use.
