Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen appliance, and more particularly to an auto steamer for automatically performing steamed and bake cooking.

[0002]

2. Description of the Related Art As a simple steamer, one in which a pot is doubled and water is put in the lower bottom and cooking ingredients are put in the upper bottom to set fire is generally popular. In addition, as a method of steaming, in a state where the frying pan and the cooking material are heated well, water is injected and the lid is covered.

[0003]

In the method of steaming with a double-bottomed pan, steaming using a frying pan and a lid is carried out because of the fact that the pan is not open, but the timing of adding water and the selection of the amount of water are It was difficult and had to rely on the cook's many years of experience. Also, pouring water into a well-heated frying pan is dangerous. An object of the present invention is to eliminate such problems and to provide an auto-steamer which can safely and reliably obtain a predetermined steaming effect.

[0004]

In order to achieve the above object, an auto-steamer according to the present invention is a top plate of a cooking table which is composed of a plate-like member made of a magnetic material and having a good flatness. A steamer box formed to create an airtight space by making close contact with the top plate, and a mechanical box for the steamer box that holds the close contact between the steamer pox and the top plate for a preset time during cooking. Connected to
For the top plate, a magnet switch that attracts with electromagnetic force only when energized, a magnet switch repels the top plate and when the close contact between the steamer pox and the top plate is released, the steamer box and cooktop are connected A flip-up arm that is mechanically connected to both the steamer box and the cooking table to hold the energy, and the energy that is placed on the back surface of the top plate that corresponds to the part where the top plate and the steamer box are in close contact with each other. The supply device comprises a timer connected to energize the magnet switch for a preset time and also to supply energy for heating the top plate.

The heating method of the top plate is induction heating by electricity,
In particular, high frequency induction heating can be used. The structure of the flip-up arm may be such that the steamer box rotates or moves in parallel with respect to the cooking table. A close contact spring can be used between the flip-up arm and the steamer box to enhance the close contact between the steamer box and the top plate. A liquid jet nozzle is provided on the inner wall of the steamer box for injecting liquid into the steamer box, and can be connected to a liquid pressure feed device including a pressure feed pump, a liquid amount solenoid valve, a liquid tank, and the like. A liquid volume controller that controls the liquid volume and timing of the liquid ejected from the liquid ejection nozzle can be provided. A temperature sensor may be provided in the steamer box to control the temperature in the steamer box to a preset temperature, and a temperature controller may be provided to adjust the energy supply for heating the top plate according to the information from the temperature sensor.
The top plate can be an iron plate.

[0006]

In the use of the auto steamer constructed as described above, first, the cooking ingredients are placed on the steamer box corresponding portion on the top plate. Timer time setting,
After setting the liquid volume, injection timing, temperature, etc., push down the flip-up arm to bring the steamer box into close contact with the top plate and bring the magnet switch close to the top plate. Then, the magnet switch is attracted to the top plate by the electromagnetic force, and the airtightness of the space surrounded by the steamer box and the top plate is maintained for the time set by the timer. A prescribed liquid is ejected from the liquid ejection nozzle at a prescribed timing and is injected into the airtight space. The top plate is heated for the time set by the timer, and the temperature in the hermetic space rises toward the temperature set by the temperature controller. The cooking material placed on the top plate is directly heated by the top plate and steamed by the generated steam. By the function of the temperature controller, the temperature of the airtight space is kept constant until the set time comes. When the set time elapses, the heating of the top plate is stopped, the electromagnetic force of the magnet switch is cut off, and the airtightness of the airtight space is automatically released. By operating the flip-up arm, cooked cooking ingredients can be taken out.

Embodiments will be described with reference to the drawings. Figure 1
The perspective view of one Example of the auto steamer concerning the present invention is shown. In this figure, the state before steaming and cooking is shown. The top plate 12 is fixed as a top plate of the cooking table. Since it forms an airtight space together with the steamer box, its surface must be extremely flat. It also satisfies the requirements that it does not deform even if a little weight is added, it does not easily corrode with water, it does not emit harmful gas even when it is heated, and it is hygienic. Further, the top plate 12 needs to be made of a magnetic material. This is because the magnet switch 13 is attracted. When the top plate heating method is induction heating by electricity, since the top plate 12 is a magnetic material, heat generation due to hysteresis loss is added in addition to Joule heat, which is particularly advantageous.

Since the steamer box 10 forms an airtight space together with the top plate 12, it is required that the edge portion corresponding to the top plate 12 has high flatness. Further, since it is in direct contact with the top plate 12 that is heated to a high temperature, it is required to have heat resistance and be a durable material that is not easily corroded by water or steam. Conductivity is not required,
Iron, aluminum or alloys containing them are suitable.

The liquid jet nozzle 11 is normally in contact with a liquid pumping device that jets a predetermined amount of water at a predetermined timing, and is controlled by a liquid amount controller 18. In addition to water, liquid preparations used in cooking, such as sake, mirin and soy sauce, can also be used.
Due to the function of the water quantity solenoid valve, the airtightness inside the steamer box is sufficiently maintained. The magnet switch 13 is mechanically connected to the steamer box 10 and has a built-in electromagnet to be attracted to the top plate 12 by an electromagnetic force. The attraction force generated by this electromagnet is sufficient to maintain the airtightness between the top plate 12 and the steamer box 10.
The reason for calling it a magnet switch is that the energy supply for heating the top plate is not performed simply by setting a timer, but is performed only when the magnet switch 13 is attracted to the top plate 12.

The flip-up arm 14 connects the steamer box 10 to the steamer box 10 for rotating or translating the steamer box 10 with respect to the cooker table. In addition to maintaining a constant contact portion, it also plays a role of holding the steamer box 10 upward when the cooking material 19 is placed or taken out before and after cooking. If no power is provided, the flip-up arm 1
Although 4 will be manually raised and lowered, it is also possible to operate it safely and surely by a hydraulic device or the like. It is advantageous in that there is no risk of burns even when the flip-up arm 14 has high heat. The contact spring 15
It is used to ensure the degree of adhesion between the steamer box 10 and the top plate 12. The pressure in the steamer box 10 increases due to the generation of steam in the airtight space. This is because the steamer box needs to be pressed against the pressure.

The timer 16 controls both the supply of energy for heating the top plate 12 and the supply of power to the electromagnet of the magnet switch 13 which maintains the airtightness in the steamer box 10, and the unit is set in seconds. The time can be set. The temperature controller 17 can set a heating temperature in advance before cooking, and controls energy for heating the top plate 12 based on information from a temperature sensor provided on the inner wall of the steamer box 10. Liquid volume controller 18
Is for setting the amount and timing of the liquid ejected from the liquid ejection nozzle. In addition to the manual setting that the cook sets each time, the machine automatically sets the appropriate liquid amount based on the set time, set temperature, etc. And automatic setting to set timing is also possible.

FIG. 2 is a perspective view of the appearance of an embodiment of the auto-steamer according to the present invention during steaming and cooking, and FIG.
It is after cooking. Since the cooking material 19 is not generally set, the cooking time, the temperature, the amount of the jetted liquid, etc. are set each time when cooking, but the frequently used materials are set in advance by operating the menu selection button or the like. It is also possible to cook at the set time and temperature.

[0013]

Since the auto-steamer according to the present invention is constructed as described above, it has an effect that a predetermined steaming effect can be obtained safely and reliably. By using induction heating with a heating method for the top plate, a clean steamer without emission of exhaust gas can be obtained. By using high frequency induction heating, higher thermal efficiency can be obtained, and depending on the frequency and the coil shape, the efficiency higher than that of gas combustion can be obtained, so that the cooking time can be shortened. By using the flip-up arm that rotates or translates the steamer box, it is possible to obtain the effect of easily ensuring the airtightness during repeated use of the machine. By using a close contact spring, it can withstand the steam pressure when steam is generated. By using the liquid jet nozzle, it is possible to safely inject water without fear of burns. A predetermined steaming effect can be repeatedly obtained by control means such as a liquid volume controller, a temperature controller, and a timer.
