Description

A device for cooking in indirect heating

The present invention relates to an automatic cooking apparatus of the indirect heating method, specifically installed in the disc-shaped heater on the outside of the bottom of the receiving portion to adjust the degree of heating and to install the drive unit including the motor under the convenience of use and operation It relates to an automatic cooking apparatus that can ensure the safety of the.

Various devices have been developed for automatically cooking food. Devices such as coffee making machines, fruit or vegetable mixers, soymilk or tofu makers, or porridge makers are miniaturized and automated in the form of convenient home use. Among these devices, in particular, soymilk or tofu makers are complex in that the grinding process and the heating process are required at the same time as compared to other cooking apparatuses, which makes it necessary to properly align the various components.

Tofu or soy milk makers that can automatically produce tofu or soy milk in cooking devices are also known in the art in various forms. Patent Application No. 10-2003-0068301 "Household porridge maker and method of manufacturing porridge using the same" is a porridge maker in which a drive unit including a motor and a control circuit is located on the upper side, and the container unit is detachably coupled to the drive unit at the bottom. It is starting.

In home tofu makers, the drive including the motor may be installed above or below. If the drive unit is installed on the upper side has the disadvantage that the stability of the head maker and handling is inconvenient while the sealing problem for the electric machine is easily solved. On the other hand, when the driving unit is installed at the bottom, the problem of stability and handling is solved, but the cost of preventing leakage of water and the like for the electric machine increases. A tofu maker having a driving unit including a motor installed under the same is disclosed in Patent Application No. 10-2004-0115661 "Food Processing Machine With Grinding and Heating Function and Food Processing Method Using the Same". The invention disclosed in this document improves the stability of the cooking apparatus itself by installing a drive unit including a motor on the lower side, but on the other hand has a disadvantage of low heating and control efficiency and inconvenient handling.

Leakage problems that may occur as the drive unit is positioned below are technical problems that can be solved according to the development of sealing technology.

The indirect heating type cooking apparatus has the advantage that the cooked food can be uniformly heated compared to the direct heating type, but has a problem that the heat efficiency is lowered because heat must be transferred through the intermediate medium. In addition, only the part where heat is needed should be supplied and the transfer to other devices should be cut off.

Another problem associated with cooking devices is that each device must be used for fruit drinks, tofu, soy milk, coffee making or for medicinal heating. The whole cooking process has to be done automatically through a series of continuous operations and at the same time it can have several advantages if several necessary foods can be made in one device. Therefore, there is a need for a complex cooking device capable of producing a variety of food.

Conventional cooking apparatuses have to be stable since most are used at home. In particular, since the device is heated through the electric device, electrical stability may be an important factor.

The present invention solves the problems with the conventional cooking apparatus presented above, and at the same time proposes a complex cooking apparatus equipped with conditions to be improved in the cooking apparatus.

Therefore, the present invention has the following object.
