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. 4, a steam cooking device
It has a boiler 1 and a steam cooking device 3 that heats and cooks food using the steam obtained by the boiler 1.

Water is supplied to the boiler 1. This boiler 1
A water supply pipe 7 is connected between the water tank 5 and the water storage tank 5. The water supply pipe 7 includes a water supply pump 9 for sending water stored in the water tank 5 to the boiler 1.
Also, check valves 11 and 12 are provided in series to prevent backflow of water.

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 led 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 led to a steam outlet pipe 15, passes through a steam trap 17, a check valve 18, a steam trap 20, a check valve 21, a valve 22, and a solenoid valve 23, and is then used for steam cooking. Guided by Vessel 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 exhaust steam to 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 heating the food, and simply discharging this steam is not efficient. The problem is that it's bad.

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, which is not efficient. do not have.

Therefore, an object of the present invention is to provide a steam cooking device that efficiently uses exhaust steam to save energy.

[Means for Solving the Problem] According to the present invention, in a steam cooking device including a steam cooker that leads water in a water storage tank to a boiler and cooks food using steam obtained from the boiler, the above-mentioned method is provided. The water storage tank has a water storage tank for water supply and an outer tank formed in opposition to the outer peripheral surface of the water storage tank, and the outer tank is provided with steam discharged from the steam cooker into the water storage tank. and steam cooking, characterized in that an exhaust steam pipe leading between the outer tank and a steam exhaust pipe for discharging the exhaust steam passing between the water storage tank and the outer tank to the outside are connected. A device is obtained.

[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 is faster.

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

The illustrated steam cooking device includes a water tank 30 and a boiler 32 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. Steam outlet pipe 42
A valve 46 and a solenoid valve 48 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 . The other end of the exhaust steam pipe 50 is connected to the steam cooker 44.

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 outer tank 54 and the water storage tank 52 into the atmosphere.

A water pipe 60 is connected to the water storage tank 52. Water 31 is supplied and stored inside the water storage tank 52 through a water pipe 60.

The water level of this water 64 is adjusted by a float valve 65 provided inside the water storage tank 52.

Now, water 31 is in the water storage tank 52 of the water storage tank 17.
is supplied, and the supply is stopped by the float valve 65 at a certain amount. Water 31 passes through the water supply pipe 35 by the drive of the water supply pump 37, and passes through the two check valves 3.
9 and 40 into the boiler 32.

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 is pressured and 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 steam exhaust 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 repeatedly performing steam cooking, the heated water 31 is guided into the boiler 32, so that the electric heater 67
The time to generate steam becomes shorter than the initial time.

In addition, as shown in Figure 3, the steam cooking device
It is housed in a single box-shaped case 70.

On one side of the case 70, there is a liquid level gauge 7 of the boiler 32.
A lid 74 having a handle 73 is provided on one side of the steam cooker 2 and the steam cooker 44.

The lid 74 is integrally provided with a food holder (not shown) that can be inserted into and removed from the steam cooking device 44 .

Therefore, by holding the handle 73 in your hand, holding the food in the food holder, and inserting it into the steam cooker 44, cooking with steam is possible.

[Effects of the Invention] As described above with reference to the embodiments, according to the steam cooker of the present invention, the water storage tank in the water storage tank can be heated using exhaust steam. Therefore, the heated water can be led to the boiler and the time required to generate steam can be shortened.

Therefore, the steam cooking device can achieve a heat retention effect simply by forming an outer tank facing the outer circumferential surface of the water storage tank, resulting in energy savings.
