Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, the outer pan of a residual heat cooker including an inner pan and an outer pan can be assembled by a heat-retaining outer lid, a heat-retaining outer wall and a heat-retaining bottom, and can be disassembled to form an outer pan before and after cooking. It relates to a residual heat cooker that makes it convenient and safe to handle the inner pot by attaching and detaching.

[0002]

[Prior art]

 A conventional residual heat cooker includes an outer pot, which is a single complete cylindrical heat retaining container, an inner pot, and an outer lid. When using, put the food to be cooked in the inner pot and heat it to a boil with a heater outside the residual heat cooker, then carry the inner pot containing the heated and boiled food from the heater into the heat insulation container and put the outer lid on. Cover and steam with food and remaining heat of inner pot to cook.

[0003]

[Problems to be solved by the device]

 In the residual heat cooker with the above structure, the inner pot must be lifted higher than the height of the outer pot when the inner pot is put in or out of the outer pot. When using a large capacity residual heat cooker of about 6 liters or more, there are the following problems. First, increasing the capacity means increasing the volumes of the inner pot and the outer pot, and increasing the height thereof. Therefore, in a large capacity residual heat cooker, the lifting height of the inner pan becomes higher, and as a result, it is not easy to lift the inner pan to the higher lifting height. This will collide with the outer pot and spill food, which is not preferable for safety. Secondly, the increase in capacity means an increase in the volume of food that can be put in the inner pot, which increases the weight, which makes it difficult for the user to handle. For example, in a commercially available Taiwanese Fukuchi 6-liter type or Japanese-made thermal magic cooker 6-liter type, the total weight of the inner pot filled with food is about 7 kg or more, and it is generally used by ordinary users. It is dangerous and difficult to lift the inner pot that has been heated to a high temperature and lift it out of the outer pot and put it in the outer pot.

The present invention provides a residual heat cooker, which has a highly safe assembled type outer cooker, which does not need to lift the inner cooker high while using a residual heat cooker, especially a large capacity residual heat cooker. The purpose is to provide a cooker.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the residual heat cooker having the assembling outer pan according to the present invention, the outer pan is formed by a heat-retaining outer lid, a heat-retaining outer wall and a heat-retaining bottom so as to be assembled and disassembled.

It is preferable that each of the heat retaining outer lid, the heat retaining outer wall and the heat retaining bottom portion of the outer pot comprises an outer shell, an inner shell spaced from the outer shell, and a heat insulating material filling the space. Not good.

The heat retaining outer wall may be formed by a plurality of arc-shaped outer wall portions, or may be formed by a single cylindrical outer wall portion.

[0008]

[Action and effect]

 When the outer pan is disassembled before cooking and the food should be cooked, the inner pan containing the food is first heated with a heater outside the cooker and boiled for a certain time, and then the inner pan containing the food is kept. It is placed on a warm bottom, and then the inner pot is surrounded by the outer wall for warming, and finally the outer cover for warming is covered to form a warming container. In this warming container, food is steamed with residual heat of the inner pot for cooking. After cooking is complete, first remove the heat-retaining outer lid and then remove the heat-retaining outer wall so that the inner pot can be easily taken out.

Since the outer pot is an assembly type and can be assembled and disassembled, when carrying the inner pot, by disassembling the outer pot, the inner pot that has been heated to boiling and has a high temperature has a lower bottom portion for keeping heat. Since it can be carried at a high height, it is easy to carry, the risk of collision between the inner pot and the outer pot in the conventional residual heat controller can be avoided, and the operational safety is enhanced.

In particular, it is easy to carry a large-capacity and heavy inner pan, and operation safety is improved. This makes it possible to put a large-capacity commercial residual heat cooker into practical use.

It is well known that energy sources in the world are limited. When the present invention is applied to a commercial large-capacity residual heat cooker, the energy saving can be expected to be 50 to 70%, which is effective for energy saving.
