Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and heating apparatus which heats food by supplying steam into a box-shaped steaming chamber and heats the heated food as it is.

[0002]

2. Description of the Related Art There is a heating device for heating food by introducing steam into a box-shaped steaming chamber having a plurality of shelves inside. Since it was different, it was not possible to carry out heating as it was, and it was necessary to transfer the food to the heating storage after the heating process was completed. For that reason, a heating and heating device that performs heating and heating by changing the steam supply amount in the heating process and the heating process was considered, but in the case of this heating and heating device, uneven temperature occurs in the steaming chamber. However, it was not possible to make uniform the state of heating or heat retention.

[0003]

The problem to be solved by the present invention is to provide a heating and heating apparatus which can directly transfer to the heating step after the completion of the steaming step and save the trouble of changing the heating step. It is to eliminate the occurrence of temperature unevenness in the steaming chamber in each of the heating step and the heating step, and to make the heating or heat retaining state uniform.

[0004]

[Means for Solving the Problems] Food is heated by introducing steam into a box-shaped steaming chamber having a steam exhaust port on the upper part and a plurality of shelves inside, and keeping heat after the heating process is completed. In the heating and heating apparatus that performs, a vertically-long side steam chamber along the vertical surface of the steam chamber, a lower steam chamber is provided in the lower part of the steam chamber, and the side steam chamber has a side steam supply pipe and a lower steam chamber. Is connected to the lower steam supply pipe, is equipped with a steam control valve that controls the amount of steam supplied to each steam chamber, and connects each steam chamber to the steam chamber through a steam outlet, and during the heating process, the side steam chamber The steam is supplied to the lower steam chamber and the steam is introduced into the steam chamber from the side steam chamber and the lower steam chamber to uniformly heat the food in the steam chamber, and the steam is supplied only to the lower steam chamber during the heating process. Then, by introducing steam into the steaming chamber only from the lower steam chamber, The food of the inner uniformly warm.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. The figure shows a heating and heating system with two steaming chambers.
FIG. 1 is a sectional side view, and FIG. 2 is a partial sectional front view with the left half being a section. The heating and heating apparatus is provided with a lower steam chamber 2 in the lower part of the box-shaped steaming chamber 1, a side steam chamber 3 in the rear part, a steam exhaust port 12 in the upper part, and a door 15 in the front. The lower steam chamber 2 and the side steam chamber 3 communicate with the steaming chamber 1 through a steam outlet 14. The side steam chamber 3 has a vertically long structure so that steam can be introduced toward each shelf 6 in the steam chamber, and a steam outlet 14 is provided so that steam enters each shelf 6. A lower steam supply pipe 4 is connected to the lower steam chamber 2, a side steam supply pipe 5 is connected to the side steam chamber 3, and the lower steam supply pipe 4 and the side steam supply pipe 5 are connected to a steam generator 10. There is. In the steaming chamber 1, there are provided 5 stages of shelves 6 each having a drawer-like shape and a hole for allowing steam to flow through on the bottom surface thereof. A dew board 16 is provided on the upper surface of the shelf 6 to heat the inside of the shelf 6. Food 7 to be added is put. A lower steam control valve 8 in the middle of the lower steam supply pipe 4, a side steam control valve 9 in the middle of the side steam supply pipe 5, a temperature detection device 13 in the steaming chamber, a lower steam control valve 8 in the upper part of the heating and storage device, and An operation control device 11 connected to the side steam control valve 9 and the temperature detection device 13 is provided. The operation control device 11 can set the heating process temperature, the heating process time, the heating process temperature, and the heating process time to arbitrary values, and controls the opening / closing of the lower steam control valve 8 and the side steam control valve 9. It should be possible to display the temperature inside the steaming room and the operating process.

When the food is heated, the heating process temperature, the heating process time, the heating process temperature, and the heating process time are set according to the food. When the food 7 is placed on the shelf and the heating process is started, the operation control device 11 starts detection of the elapsed time and displays that it is the heating process. Operation control device 11
Controls the lower steam control valve 8 and the side steam control valve 9 so that the temperature of the steaming chamber obtained from the temperature detecting device 13 becomes the heating process temperature, and the steam from the steam generating device 10 is
It passes through the lower steam control valve 8 and the side steam control valve 9 and is fed into the lower steam chamber 2 and the side steam chamber 3. The steam sent to the lower steam chamber 2 and the side steam chamber 3 is introduced into the steaming chamber 1 through the steam outlet 14 and the steaming chamber 1
The food 7 inside is heated. When the elapsed time being detected reaches the heating process time, the operation control device 11 changes the process from the heating process to the heating process, starts detecting the elapsed time in the heating process, and determines that the heating process is performed. Is displayed. The operation control device 11 controls only the lower steam control valve 8 to open and close so that the temperature of the steaming chamber obtained from the temperature detection device 13 becomes the temperature of the heating process, and the side steam control valve 9 remains closed. When the lower steam control valve 8 is opened, the steam from the steam generator 10 is supplied to the lower steam chamber 2, and the steam is introduced into the steaming chamber 1 from the lower part. Door 15 as needed during the heating process
Open and take out the heated food. Since the deterioration of food progresses if the storage time is prolonged, when the detected elapsed time reaches the storage process time, the end of the storage process is output and the remaining food is taken out.

During the heating process, the lower steam chamber 2 is moved into the steaming chamber 1.
Since the steam is introduced from both of the side steam chamber 3 and the side steam chamber 3, the foods 7 in the steaming chamber 1 can evenly contact the steam and heat the foods 7 evenly. During the warming process, the door 15 is opened and closed. When the door 15 is opened, the steam having a higher temperature is discharged from the inside of the steaming chamber 1, and instead, the low temperature air enters the steaming chamber 1. Since the low-temperature air has a large specific gravity, the low-temperature air gathers in the lower part of the steaming chamber, and a temperature difference occurs between the upper part and the lower part in the steaming chamber 1.
At the time of warming, by introducing steam only from the lower steam chamber 2 and raising the temperature of the lower part of the steaming chamber 1, the temperature difference between the upper and lower parts in the steaming chamber 1 can be eliminated, and each food 7 is kept warm evenly. You can
