Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cooker using induction heating used in general households.
[0002]
[Prior art]
A conventional household tabletop cooker has a configuration in which a metal pan is heated by a sheathed heater, and a cooked product is heated by heat conduction from the pan. Recently, there is also an electromagnetic cooker that uses an induction heating method to directly heat a pan by electromagnetic induction. However, in these cookers, there is a large difference in temperature between the surface in contact with the pan and the other side, and uniform baking is difficult. In addition, in cooking such as steaming, a large amount of water is put in a pan in advance and cooking is performed with steam at 100 ° C., so that there is a problem that the cooking time becomes long.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and uses a superheated steam of 100 ° C. or higher, and has a simple structure that can be cooked quickly without losing moisture of the ingredients while circulating water and steam more effectively and safely. The purpose is to provide vessels.
[0004]
[Means for Solving the Problems]
One of the means of the present invention for achieving the above object includes a water tank for supplying water, a steam generating means for heating the water supplied from the water tank, and the steam from the steam generating means at a higher temperature. It comprises a steam superheating means for heating, a cooking container, and a lid, and the superheated steam from the steam superheating means can be supplied from the upper part and the lower part of the cooking container, and dew condensation water is provided by a drain outlet provided at the lower part of the cooking container. In this case, water that has been purified is supplied to a water tank through a filter, and a cooker that enables uniform cooking of cooked food is provided.
[0005]
Thereby, since superheated steam can be applied to a to-be-cooked object from the upper and lower sides of a cooking container, it can cook evenly.

It is. In FIG. 1, water in a water tank 1 enters two steam generating means and is heated by a heater or the like. Here, the steam becomes 100 ° C., and only the steam flows into the steam superheating means 3. Here, the steam superheating means 3 has a configuration in which a heating coil is wound around a foam metal. Thus, when the steam passes through the mesh of the foam metal, heat is transferred from the foam metal that has become high temperature by induction heating, and becomes high-temperature superheated steam of 100 ° C. or higher.
[0012]
FIG. 2 shows a circuit configuration diagram of this apparatus. In FIG. 2, 9 is a heater, 10 is a switch, 11 is a heating coil, 12 is a switching element, 13 is a drive circuit, and 14 is a control circuit. Here, a control signal output from the control circuit 14 is input to the drive circuit 13, the switching element 12 is operated by this drive circuit, and a high-frequency current is passed through the heating coil 11. The superheated steam passes through the metal foam heated by the magnetic field generated by the high-frequency current, passes through the flow path, and hits the food from the two superheated steam generation ports 7 that pass through the upper and lower portions of the cooking vessel. . With this configuration, the superheated steam is evenly distributed in the cooking container 4, and steamed dishes using grilled food or steam can be made.
[0013]
FIG. 3 is a block diagram of a cooking device using the second means. Reference numeral 15 in FIG. 3 denotes supply switching means. By this supply switching means 15, for example, the start of cooking does not pass steam for a certain period of time, and it is possible to allow steam to pass after the temperature of the steam rises. It is also possible to supply superheated steam only from either one of the upper and lower sides. For example, in the case of a frozen food in a container, it is efficient to supply steam only from above. In this way, the supply switching means 15 enables a cooking method according to the food to be cooked.
[0014]
(Example 2)
Embodiments of the third, fourth and fifth means of the present invention will be described below with reference to the drawings. 4, 5 and 6 are block diagrams of the cooking device.
[0015]
In FIG. 4, 1 is a water tank, 2 is steam generating means, 3 is steam superheating means, 4 is a cooking container, 5 is a lid, 6 is a net on which food is placed, 7 is a superheated steam generating port, and 8 is a housing. , 16 is a heating means of the cooking container. When the entire cooking container is cold, the superheated steam enters the cooking container and immediately condenses. In order to prevent this, the heating means 16 such as a heater is embedded in or brought into contact with a cooking container made of aluminum or the like, and the temperature of the container is kept at 100 ° C. or higher, so that the superheated steam does not decrease the temperature and heats the object to be cooked. , And you can make various dishes delicious .
[0016]
Further, as shown in FIG. 5, when condensed water is collected and purified through the filter 18 and used again as superheated steam, energy saving is achieved, and overall high efficiency can be achieved.

In FIG. 7, the water in the water tank 1 enters the steam generating means 2 and is heated by a heater or the like. Here, the steam becomes 100 ° C., and only the steam flows into the steam superheating means 3. Here, the steam becomes a high-temperature superheated steam of 100 ° C. or higher by the steam superheating means 3. And cooking can be performed when cooking. At this time, the cooking container 4 is filled with steam or superheated steam even after cooking is completed, and there is a risk of burns when the lid is opened. Accordingly, the steam in the container is quickly collected by the suction fan 19 and purified through the filter 18 so that it can be reused. With this configuration, a safer cooker can be provided.
