Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a steam cooking device used for cooking food using steam.

[Prior Art] Conventionally, as shown in FIG. 7, a steam cooking device
It has a boiler 1 and a steam cooker 3 that heats and cooks food using the steam obtained by the boiler 1. Water is supplied to the boiler 1.

A water supply pipe 7 is connected between the boiler 1 and the water storage tank 5. The water supply pipe 7 includes a water supply pump 9 for sending water stored in the water storage tank 5 to the boiler 1, and a check valve 1 for preventing backflow of water.
1 and 12 are provided in series.

Furthermore, between the boiler 1 and the steam cooker 3,
A steam outlet pipe 15 is connected.

A steam trap 17, a check valve 18, a steam trap 20, a check valve 21, a valve 22, and a solenoid valve 23 are connected in series to the steam outlet pipe 15 from the boiler 1 side.

Water is now supplied and stored in the water tank 5 connected to the water pipe 25. The water in the water tank 5 is guided to the water supply pipe 7 by the drive of the water supply pump 9, passes through the check valves 11 and 12, and is stored inside the boiler 1.

Inside boiler 1, an electric heater (not shown)
The water is heated and steam is obtained.

The steam obtained in the boiler 1 is transferred to the steam outlet pipe 15
Steam trap 17, check valve 18,
Steam trap 20, check valve 21, valve 22
It passes through the electromagnetic valve 23 and is led to the steam cooker 3.

Food is stored in the steam cooker 3 and the food is heated and cooked.

The steam cooker 3 is connected to an exhaust pipe 27 for exhausting steam after heating.

The exhaust pipe 27 serves to release the exhaust steam into the atmosphere.

[Problems to be solved by the invention] However, the temperature of the steam released into the atmosphere from the exhaust pipe 27 is quite high even after the food is heated, and it is said that it is inefficient to only discharge this steam. There's a problem.

That is, when heating the food inside the steam cooker 3, the amount of steam generated in the boiler 1 is large, so the electric heater that turns water into steam in the boiler 1 is energized for a long time, making it less efficient. I can not say.

In addition, a water storage tank 5, a boiler 1, and a steam cooker 3
Since these are separate bodies, the steam outlet pipe 15 between the boiler 1 and the steam cooker 3 is particularly long.

Therefore, the steam outlet pipe 15 has large heat loss and pressure loss, and is therefore not efficient.

Therefore, an object of the present invention is to provide a steam cooking device that performs efficient steam cooking by housing the steam cooking device in one case and forming a cooking surface in this case. It is in.

[Means for Solving the Problems] According to the present invention, there is provided a water tank for storing water, a pump for guiding water from the water tank, an electric boiler for heating the water sent by the pump, and a A steam cooker for cooking food using the steam produced is housed in a single case, and a part of the top surface of the case is lower than the other top surface of the case to form a cooking table surface. A steam cooking device is obtained, characterized in that the steam cooking device is housed in the case below the table surface.

[Function] In the steam cooking device of the present invention, steam derived from the boiler is guided to the steam cooker, and food is heated and cooked in the steam cooker.

The steam after cooking the food is guided to the outer peripheral surface of the water storage tank, and the water storage tank is heated.

Therefore, the water inside the water storage tank is heated by the exhaust steam and led to the inside of the boiler.
The time to generate steam becomes faster.

In addition, since the case has a cooking table surface, a food holder pulled out from steam cooking can be placed thereon, or cooking utensils can be placed thereon.

[Embodiment] FIGS. 1 to 3 show an embodiment of the steam cooking apparatus of the present invention.

The illustrated steam cooking apparatus includes a water tank 30 and a boiler 32 such as an electric boiler that heats water 31 in the water tank 30 to produce steam.

A water supply pipe 35 is connected between the water tank 30 and the boiler 32. The water supply pipe 35 is provided with a water supply pump 37 for guiding water 31 in the water storage tank 30 to the boiler 32 and two check valves 39 and 40 in series.

On the other hand, the boiler 32 is connected to a steam cooker 44 via a steam outlet pipe 42.

The steam outlet pipe 42 includes a valve 46 and a solenoid valve 4.
8 are provided in series.

The water storage tank 30 includes a water storage tank 52 and an outer tank 54 formed to face the outer peripheral surface of the water storage tank 52. A heat insulating material 56 is provided on the outer peripheral surface of the outer tank 54.

One end of an exhaust steam pipe 50 for sending steam discharged from the steam cooker 44 to the space between the water storage tank 52 and the outer tank 54 is connected to the outer tank 54 .

Further, a steam exhaust pipe 58 is connected to the outer tank 54 for discharging the exhaust steam that has passed through the space between the tank 54 and the water storage tank 52 into the atmosphere.

A water pipe 60 is connected to the inside of the water storage tank 52.

Water 31 is supplied and stored inside the water storage tank 52 through a water pipe 60. The level of this water 64 is adjusted by a float valve 65 provided inside the water storage tank 52.

Such a steam cooking device is housed in a single box-shaped case 70, as shown in FIG. On one side of the case 70, a liquid level gauge 72 of the boiler 32 and one side of the steam cooker 44 are provided. A lid 74 having a handle 73 is provided on one side of the steam cooker 44, as shown in FIG. A food holder 80 that can be inserted into and removed from the steam cooker 44 is integrally provided on the lid 74 .

Therefore, if you hold the handle 73 in your hand, hold the food, and insert it into the steam cooker 44,
Cooking with steam is possible.

A cooking table surface 82 is formed on the upper surface of the case 70, with a portion of the surface lower than the other upper surface of the case 70.

A steam cooker 44 is housed below this cooking table surface 82, that is, inside the case 70.

Now, there is water 31 in the water storage tank 52 of the water storage tank 30.
is supplied, and the supply is stopped by the float valve 65 at a certain amount.

Water 31 is guided into the boiler 32 through the water supply piping 35 by the drive of the water supply pump 37 and through the two check valves 39 and 40.

The boiler 32 is provided with an electric heater 67. Water 31 stored inside the boiler 32 is heated by the electric heater 67 to generate steam.

This steam gains pressure and is sent from the steam outlet pipe 42 to the steam cooker 44 via a valve 46 and a solenoid valve 48.

Food is provided inside the steam cooker 44, and the food is heated and cooked by steam.

The steam after cooking passes through the exhaust steam pipe 50,
It enters the space between the water storage tank 52 and the outer tank 54. (See the arrows in FIG. 1) This exhaust steam heats the outer circumferential surface of the water storage tank 52 and reaches the steam exhaust pipe 58, whereupon it is released into the atmosphere.

At this time, the water 31 in the water storage tank 52 is heated by the exhaust steam. Therefore, when steam cooking is repeatedly performed, the heated water 31 is guided into the boiler 32, so the time for generating steam by the electric heater 67 becomes shorter than the initial time.

In addition to the cooking table surface 82 having the shape shown in FIG. 4, the case 70 can also have a cooking table surface 82 having the shape shown in FIG. 6.

In this case, the boiler 32 is installed at the rear of the case 70.
is located.

[Effects of the invention] As explained above with reference to the embodiments, according to the steam cooking device of the invention, since the steam cooking device is housed in one case, the steam outlet pipe becomes short, thereby reducing heat loss, Pressure loss is reduced, resulting in energy savings.

In addition, the case has a cooking surface, so
The food holder of the steam cooker located under the cooking table surface can be taken out and placed on the cooking table surface immediately, making the work easier.
