Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a device for generating steam for steaming and heating food such as steamed buns and sushi.

[Conventional technology]

Conventionally, when heating food such as steamed buns, sushi, etc. in stores, a method of heating by steaming is mainly used, and as a heat source, an electric heating element is provided around the water storage container or in water, There are an electric heater for boiling water to generate steam and a combustion device for burning fuel such as gas and oil and boiling the hot water to generate steam.

[Problems to be solved by the device]

However, in these methods, since the entire water contained in the water storage container has to be heated, a large-capacity heating element and a combustion device having a certain degree of thermal power are required, and the thermal efficiency is not good.

In addition, it takes a considerable amount of time before the entire water is heated and steam is generated.

Furthermore, when a flame is used, there is a risk of flammable combustible materials being ignited.

[Means for Solving the Problems]

The present invention is intended to address these problems, and the object could be achieved by completing the invention described below.

The steam generator of the present invention is provided with an ultrasonic humidifier for generating mist-like water droplets and an electric heater provided with a heating element for heating the mist-like water droplets generated by the ultrasonic humidifier, respectively. The ultrasonic humidifier and the electric heater are connected by a connecting tube, and a blower is provided for sending mist-like water droplets generated by the ultrasonic humidifier into the electric heater through the connecting tube. A structure in which a return communication tube for returning the gas heated in the electric heater back to the ultrasonic humidifier and circulating it is provided integrally with the blower provided in the ultrasonic humidifier. Is.

The electric heater has a plurality of heating elements for heating mist-like water droplets inside, and an outlet for discharging the vaporized water vapor that has been heated at the top.

The ultrasonic humidifier is a normal humidifier and has a container for storing water inside.

The blower removes mist-like water droplets generated by the ultrasonic humidifier.
In order to be sent into the electric heater through the connecting tube,
It is connected to an ultrasonic humidifier via a feed connecting tube that discharges air.

The return communication tube is for returning the heated gas to the ultrasonic humidifier again and circulates it, and is provided so as to connect the electric heater to the air suction side of the blower provided in the ultrasonic humidifier. Has been.

With the above-described configuration, mist-like water droplets are sequentially fed into the electric heater to be heated by being brought into contact with a heating element provided inside to generate steam by vaporization. .

Further, the present invention is also a centrifugal spray type humidifier that uses a centrifugal force to generate water droplets.

[Action]

The water droplets atomized by the ultrasonic vibration of the ultrasonic humidifier are sequentially sent into the electric heater by the wind generated by the blower, and contact with the heating element that has generated heat due to electrical resistance. In addition, the return communication tube is installed to connect the electric heater to the air suction side of the blower, so that the suction force of the blower sucks in the gas heated in the electric heater and the ultrasonic wave is generated. It can be easily fed into the humidifier and circulated, and steam can be generated more efficiently.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The present invention, as shown in FIG. 1, is an ultrasonic humidifier (6) for generating mist-like water droplets, and a heating element for heating and evaporating the mist-like water droplets generated by the ultrasonic humidifier (6). An electric heater (1) provided with (2) is separately provided, and the ultrasonic humidifier (6) and the electric heater (1) are connected by a connecting tube (4). ) And the atomized water droplets generated by the ultrasonic humidifier (6) can be sent to the electric heater (1) through the communication tube (4). A blower (9) for facilitating the feeding into the electric heater (1) is provided in the ultrasonic humidifier (6) through a feed communication tube (7) for discharging air, and further inside the electric heater (1). The return communication cylinder (11) for returning the gas heated by the above into the ultrasonic humidifier (6) and circulating it,
A steam generator (A) which is integrally provided so as to be connected to the blower (9) provided in the ultrasonic humidifier (6).
It is what

The electric heater (1) has a plurality of heating elements (2) for heating mist-like water droplets inside, and also has a discharge port (3) for discharging heated and vaporized water vapor in the upper part. There is something. At this time, as the heating element (2), for example, several pieces of about 100 W in which a nichrome wire is insulated with silica and packed in a pipe may be prepared. Further, the atomization amount of the ultrasonic humidifier (6) may be set to a desired amount.

As shown in FIG. 2, the steam generator (A) thus constructed is integrally connected to the lower portion of the showcase (B) in which food such as steamed buns and sushi is put, and is used as a food heating steamer (C). First, the electric heater (1) is turned on to bring the heating element (2) into a heating state, and then the ultrasonic humidifier (6) is activated to generate mist-like water droplets. When the water droplets are blown into the electric heater (1) by the blower (9) through the connecting cylinder (4), the mist-like water droplets fed into the electric heater (1) generate heat. When it comes into contact with the body (2) and is heated and vaporized, it becomes steam from the discharge port (3) and is discharged.
The food (10) such as sashimi is steamed and heated, and the gas heated in the electric heater (1) is sucked in by the suction force of the blower (9) through the return communication tube (11), By being sent into the ultrasonic humidifier (6) and circulating, the steam can be generated more efficiently.

Further, as another embodiment of the present invention, although not particularly shown, the ultrasonic humidifier (6) of the above embodiment is integrally configured as a centrifugal spray humidifier that generates water droplets by centrifugal force. It is a steam generator.

〔effect〕

The steam generator of the present invention is designed to generate water vapor in the form of mist in advance, heat it to generate water vapor, and discharge the water vapor from the discharge port to heat food or the like. It is possible to easily generate steam even with the heating element of, and it is not necessary to heat all the water contained in the heating container, so it has extremely good thermal efficiency,
Moreover, by providing the return communication tube so as to connect the electric heater and the air suction side of the blower, the heated gas returns to the ultrasonic humidifier again and is circulated. It can be said that the thermal efficiency is good.

Further, since it is possible to immediately generate steam, the time required for heating the food or the like is considerably shortened, and the work efficiency is high.

Furthermore, since it is used as energy for heating electricity, it is safe and does not easily ignite other combustible materials like a flame.
