Energy-saving cooking device

The present invention relates to a cooking apparatus, and more particularly to an energy-saving cooking apparatus.

According to the central kitchen and restaurant operators, in order to supply a large number of meals in a short period of time, large cooking devices are usually used to cook foods, such as steam boilers (as shown in Figure 1), which are heated by steam when heated. The cooked food and the steam pressure system can determine the cooking temperature and the length of the cooking time. It can be used to efficiently cook a variety of different foods, so that the cooking time can be greatly reduced, which is indispensable for large group meals. device.

Generally, referring to Fig. 1, the steam boiler includes a container 1, a heating chamber 2, and a heating portion 3, wherein the accommodating space 10 formed by the inner wall of the container 1 is for accommodating the food. The heating chamber 2 is disposed on the outer wall of the bottom and the periphery of the container 1, and is a hollow closed space formed between the bottom of the container 1 and the surrounding outer wall, and water or heat transfer oil is added to the heating chamber 2, However, the water or heating oil does not fill the entire heating chamber 2, and it is necessary to leave a part of the space in the heating chamber 2. In addition, a pressure relief valve 4 is further connected to the heating chamber 2. Further, the heating portion 3 is disposed at the bottom of the heating chamber 2, and the heating portion 3 is to burn the gas to the bottom of the heating chamber 2, so that the water or the heat-conducting oil of the heating chamber 2 is heated, thereby converting the water to the temperature. The water vapor warms the container or warms the heat transfer oil, so that the temperature of the container 1 can be indirectly heated through the heating chamber 2, thereby cooking the cooked food.

According to the above, when the user uses the gas ignition to heat the indirect heating portion 3, the water or heating oil of the heating chamber 2 will gradually expand and fill the entire heating chamber 2, and the pressure value in the heating chamber 2 reaches the pressure relief. When the safety pressure value set by the safety valve 4 is set, the pressure relief valve 4 connected to the heating chamber 3 is opened to discharge the water vapor or to recover the expanded heating oil into the recovery device to prevent the heating chamber 2 from being heated. The pressure value is too high and an explosion occurs. In the container 1, the food in the container 1 is indirectly heated by the steam containing the high calorific value or the heating oil through the outer wall of the container 1, and the food is continuously turned until the cooking is completed.

However, when the heating portion 3 burns the gas to heat the heating chamber 2, most of the heat energy of the combustion gas is lost in the air, in other words, the heating portion 3 burns the gas to heat the heating chamber, and the heating chamber 2 obtains The heat energy is not high. In addition, the hot air (or hot exhaust gas) generated by the combustion of the heating portion 3 is also dissipated in the air, which is quite wasteful of the heat energy generated when the heating portion 3 burns the gas. Therefore, it is extremely There is a need to improve the structure of the current large-scale cooking apparatus, so that the heat energy of the combustion unit 3 to burn the gas can exert greater thermal efficiency.

In view of the problems of the prior art, in order to solve the deficiencies of the prior art, an object of the present invention is to provide a cooking device capable of effectively utilizing the heat energy generated by burning gas, and providing a hot air which can effectively utilize the combustion gas.

Since the foodstuff is contained in the container 5 during cooking, in order to prevent the foodstuff from falling out of the container 5, and the space for frying is reserved, the foodstuff is not filled therein, and therefore, the heating chamber 6 is usually taken from the container 5. The bottom portion extends upwardly to cover a portion of the outer wall surrounding the container 5 such that the top edge of the heating chamber 6 is spaced from the top edge of the container 5 such that the food material is uniformly heated.

Referring to FIGS. 1 and 2, the energy-saving heating portion 7 includes a combustion chamber 70 and a plurality of heat-conducting bodies 71, wherein the combustion chamber 70 is wound around a surface of the heating chamber 6, particularly the combustion chamber 70.

Further, one end of the combustion chamber 70 is supplied with fuel (e.g., gas), and the other end of the combustion chamber 70 is exhausted. Moreover, each of the heat conductors 71 is disposed in the combustion In the firing chamber 70, each of the heat conductors 71 absorbs and conducts the heat energy after the combustion of the fuel to the surface of the heating chamber 6, so that the heat conductive material 60 in the heating chamber 6 is heated, thereby providing thermal energy into the container 5 to be inside the container 5. The ingredients are indirectly heated and the ingredients are constantly turned until the dishes are finished. In one embodiment of the invention, each of the heat conductors 71 is evenly dispersed within the combustion chamber 70 to allow rapid and even conduction of thermal energy into the heating chamber 6. Further, each of the heat conductors 71 may be disposed in the combustion chamber 70 in accordance with the heat of combustion obtained by the combustion chamber 70 receiving the inlet and outlet of the fuel to allow the heat energy to be conducted to the heating chamber 6 more quickly and more evenly. Furthermore, each of the heat conductors 71 is a hollow tubular body.
