DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steamer for business use for thawing or steaming frozen foods, and more particularly to a steamer for making the internal temperature uniform while effectively utilizing heat.

[0002]

2. Description of the Related Art A conventional steamer has a structure that supplies high-temperature steam and discharges steam having a lowered temperature. That is, high-temperature steam is discharged after passing through the food loaded on the cart in the steamer.

[0003]

However, in the above-described steamer, the heat of the steam cannot act evenly on the food, and the state of the steamed food may vary depending on the place placed inside the steamer. . In other words, the steam was well steamed in the vicinity of the steam supply port, and was insufficient in the space away. In addition, the steam was discharged in a state containing heat, and the heat of the steam was not sufficiently utilized. Therefore, the applicant has developed a steaming apparatus disclosed in Japanese Patent Application Laid-Open No. 6-304069. The steamer is provided with an exhaust duct opening near the bottom, and a steam supply unit that supplies steam to a sparge pipe disposed at the bottom of the steamer while being inserted into the exhaust duct, Heat loss is suppressed. However, the temperature in the steaming chamber cannot be made nearly uniform, and the convection of the steam inside the steaming chamber is natural convection, and the speed of the steaming process has not been improved. That is, the high-temperature steam supplied from the sparge pipe provided at the bottom rises and moves upward in the steaming chamber, then gradually descends as the temperature decreases, and is discharged outward through the exhaust duct. This discharge was performed by the pressure (positive pressure) of the supplied steam. Therefore, since the heat energy of the steam is released from the bottom of the steaming chamber after being released in the steaming chamber, the speed of transferring heat to food is low although the heat is effectively used,
It took a long time to process.

[0004] In view of the above points, the present invention is to improve the processing speed while using a steaming device with less heat loss, and to improve the processing state of food by making the internal temperature uniform. The purpose is to provide a steamer that can be used.

FIG. 1 is a block diagram showing an embodiment of the present invention.
A description will be given based on FIG. FIG. 1 is a front view of the steamer 1, FIG. 2 is a side view, and FIG. 3 is a plan view.
First, as shown in the figure, the steamer 1 is provided with a door 2 that can be opened and closed on the front side, so that the cart 3 can be carried into the steamer 1. Further, a steam supply unit 4 is provided so as to pass through the rear side wall of the steam storage 1 and,
A sparge pipe 5 connected to the steam supply unit 4 is provided near the bottom of the steam storage 1. The steam supply unit 4 is inserted into an exhaust duct (not shown), and the steam supply unit 4 is kept warm by the slightly low-temperature steam passing through the exhaust duct, and is kept until the steam supply unit 4 is ejected from the sparge pipe 5. Prevents heat loss from steam. The exhaust duct has an exhaust port that opens at the bottom of the steamer 1, and is naturally exhausted so as to be pushed out by steam that is forcibly supplied into the steamer 1. The exhaust duct is opened above the steamer 1 and discharged to the outside of the steamer 1. Further, a blower 6 is provided at the upper part of the steamer 1, so that the outside air can be forcibly supplied into the steamer 1.

Therefore, hollow portions 13 and 14 are provided in appropriate ranges of the left and right side walls 11 and 12 of the steam storage 1 as described above. The upper part of the left side wall 11 is located at the air outlet 15 of the blower 6.
On the other hand, an air supply pipe 16 is connected to an upper portion of the right side wall 12, and the air supply pipe 16 is connected to an intake port 18 of the blower 6 via a switching valve device 17. Have been. Therefore, when the blower 6 is started, air inside the hollow portion 14 provided on the right side wall 12 can be forcibly blown to the hollow portion 13 provided on the left side wall 11. The switching valve device 17
The outside air intake 19 is opened upward, and the outside air can be sucked in by switching a valve inside the switching valve device 17.

Next, the details of the side walls 11, 12 will be described. First, as shown in FIG. 4, an infinite number of circular steam inlets 21 are formed in the inner wall surface of the left side wall 11.
The steam inlet 21 penetrates a hollow portion 13 provided inside the side wall 11, and allows steam forcibly supplied by the blower 6 to flow into the steam storage 1 from the steam inlet 21. You can do it. That is, since the hollow portion 13 inside the side wall 11 is provided so as to reach almost the entire area of the side wall 11 and furthermore, constitutes an integrated space, the steam supplied to the hollow portion 13 slightly increases. It is pressurized and can flow in from the steam inlet 21. On the other hand, as shown in FIG. 5, an infinite number of elliptical steam outlets 22 are formed in the inner wall surface of the right side wall 12. The steam outlet 22 also penetrates through the hollow portion 14 provided inside the side wall 12, and the hollow portion 14 is provided almost over the entire area of the side wall 12.
2 are provided through the single hollow portion 14. Since the hollow portion 14 is continuous with the air supply pipe 16, the steam is sucked by the start of the blower 6, the internal pressure of the hollow portion 14 is slightly reduced, and each of the steam outlets 22. The steam inside the steam storage 1 can be inhaled from the inside.

In this embodiment, as shown in FIG. 6, while the steam is supplied from the sparge pipe 5 to the inside of the steamer 1 as shown in FIG. Is forced into the hollow portion 13 on the left side, so that an airflow from the left side wall 11 to the right side wall 12 is generated inside the steaming chamber 1, and the steam supplied to the steaming chamber 1 is Since it can flow around the food, the heat of the steam can be quickly transmitted to the food. At this time, when the steam flowing in from the steam inlet 21 is extremely fast, the inside of the steamer 1 is agitated, so that the heat of the supplied steam is transmitted to other steam and conversely, the heat loss is reduced. In addition, if the inflow is extremely slow, only the processing of the food located near the steam inlet 21 is promoted, and the uniform processing is hindered. A spill is desired. In addition, if the blower 6 used for taking in outside air is adopted, steam can be made to flow in at a relatively moderate speed.

It is needless to say that various embodiments can be adopted without departing from the spirit of the present invention. For example, in the above embodiment, the shape of the steam inlet 21 is circular and the shape of the steam outlet 22 is elliptical. However, these shapes do not affect the present invention, and may be configured in any shape. Can be. The steam outlet 22 is larger than the steam inlet 21 so that the steam flows inside the steamer 1 smoothly. This means that a weak positive pressure acts on the steam inlet 21 and a weak negative pressure acts on the steam outlet 22. When the steam given the positive pressure flows into the inside of the steam storage 1, the direction of the negative pressure is changed. At this time, if the steam outlet 22 is largely open, the moved steam can be allowed to flow out from the steam outlet 22 and generate a stable convection inside the steamer 1. Because you can do it. Although not described in the above embodiment, the steam storage 1 is provided with a control device next to the door 2 to control the supply of steam while detecting the internal temperature, and to set a predetermined processing time. When it reaches, the supply of steam is stopped, the valve inside the switching valve device 17 is switched, the outside air is taken into the steam storage 1 by the blower 6, and the operation is performed so that the door 2 can be opened and closed when the internal temperature decreases. Is done.

As described above, the present invention provides a door that can be opened and closed, an exhaust port provided near the bottom, an exhaust duct that is continuous with the exhaust port and that opens outside the ceiling, and a door near the bottom. A steam supply unit that supplies steam to a sparge pipe to be provided, and a steamer including a blower that forcibly supplies outside air, a hollow portion is provided inside one of the side walls adjacent to the door, and an inner wall surface is provided. An infinite number of steam inlets are provided, a hollow portion is provided in the other side wall, and an infinite number of steam outlets are provided in the inner wall surface, and a continuous space is provided between the hollow portions on both side walls via a blower. A flow passage is provided, and
The lower is also used as the blower for forced supply of outside air,
When forcibly circulating the passage and when forcing outside air
At the same time, since the steamer is characterized by being able to switch the flow path, it is possible to flow the steam inside the steamer while supplying high-temperature steam from the steam supply unit,
