2 is a cross-sectional view illustrating a cooking vessel according to the present invention. Referring to FIG. 2, the cooking vessel holder 12 is positioned on the heat source 10, and the cooking vessel 14 is mounted on the cooking vessel holder 12. The cooking vessel 14 may have various shapes as a container for heating the food 16 accommodated therein, and a cover 18 may be mounted on an upper portion thereof to seal the container. As a preferred example, the cooking vessel 14 is a container for cooking food 16 for a long time, such as a cauldron, bear pot.

The heat source 10 shown in FIG. 2 is an electric heater, but may be replaced with various known heat sources such as a gas burner. For example, the cooking vessel holder 12 may have various shapes in which openings are formed to pass the heat of the heat source 10 to the cooking vessel 14 while passing through the cooking vessel 14 such as an oven or a grill. 2 illustrates a state in which only a single cooking vessel 14 is mounted on the cooking vessel holder 12, this is to help understanding the structure of the cooking vessel in the present invention, which will be described below with reference to FIG. 5. As described above, a plurality of cooking vessels are mounted.

As shown, the steam collecting tube 20 is connected to the cover 18 of the cooking vessel. One end of the steam collecting tube 20 extends through the cover 18 to the inside of the cooking vessel 14.

As another example, as illustrated in FIG. 3, the vapor collecting tube 20 may be connected to an upper side of the outer wall of the cooking vessel. As such, when the steam collecting tube 20 is connected to the upper side of the cooking vessel instead of the lid 18, the lid 18 can be opened and closed freely regardless of the steam collecting tube 20.

The other end of the steam collecting tube 20 is connected to the waste heat recycling system 30 side. As the steam valve 22 installed on the steam collecting pipe 20 is opened and closed, steam generated in the cooking vessel 14 moves to the waste heat recycling system 30. The waste heat recycling system 30 will be described later with reference to FIG. 5.

The steam collecting tube 20 can be opened and closed by manual operation. However, preferably, by sensing the evaporation point at which the food 16 in the cooking vessel 14 evaporates and automatically opening and closing the vapor collecting tube 20, the heating time until the food 16 reaches the evaporation point is inhibited. Increase the waste heat recovery efficiency.

As shown in the illustrated example, the sensor means 24 for measuring the pressure or temperature inside the cooking vessel 14 is installed inside the cooking vessel 14. The sensor means 24 is a means for detecting an evaporation point at which the food 16 inside the cooking vessel 14 evaporates. The sensor means 24 may be a known temperature sensor or a pressure sensor, or may be an integrated sensor in which the temperature sensor and the pressure sensor are integrated.

The control unit 26 may be configured as an analog circuit such as switching the power of the steam valve 22 in accordance with an analog signal such as the output voltage of the sensor means 24. As another example, the control unit 26 may include a microprocessor, and may be configured as a digital circuit for AD converting and recognizing the output of the sensor means 24 and outputting a digital control signal. In this case, the microprocessor can adjust the output level setting value of the sensor means 24 according to the type of food. In addition, the set point for controlling the opening of the steam valve 22 in the microprocessor may be set slightly higher than the actual evaporation point of the food.

As shown in FIG. 2, the cover 18 is further provided with a safety valve 28 for releasing steam inside the cooking vessel 14 to the outside. The safety valve 28 is used to release the pressure inside the cooking vessel 14 when the pressure inside the sealed cooking vessel 14 is abnormally increased.

The safety valve 28 can be opened and closed manually. Preferably, the safety valve 28 is also automatically controlled to open and close. For example, the control unit 26 controls to open the safety valve 28 when the temperature or pressure detected by the sensor means 24 indicates an abnormal state. As another example, the safety valve 28 may have its own pressure sensing function to actuate itself to open when the pressure is high.

2, the water supply pipe 40 for supplying water into the cooking vessel 14 is connected to the upper side of the cooking vessel 14. And the water supply pipe 40 is provided with a water supply valve 42 can open and close the supply of water. The water supply valve 42 may be operated manually, but is preferably configured to be automatically supplied when there is a lack of water by moisture evaporation of the food.

To this end, the level sensor 44 for detecting the water level of the food 16 is installed in the cooking vessel 14. The controller 26 replenishes the water in the cooking vessel 14 by opening the water supply valve 42 when the water level detected by the level sensor 44 falls below the set value. The water supply is run for a predetermined time.

As another example, the level sensor for detecting the high water level may be further mounted, and the control unit 26 may control to close the water supply valve 42 according to the output of the level sensor for detecting the high water level.
