[Industrial applications]

 The present invention relates to a heating cabinet for holding processed foods in a heat-retaining state without long-term deterioration.

[0002]

[Prior art]

 Traditionally, bento and prepared foods are intensively cooked in food processing plants, for example, from late night to early morning, and delivered to supermarkets, convenience stores, general stores or factories.

[0003] In this case, the food is usually used for food through a process of cooking → cooling → transportation → refrigeration → heating. However, such a process not only increases various expenses but also Moisture is scattered and the flavor is reduced.

In addition, a heater or the like may be used to store the product for a long period of time while maintaining the heat retention state. In this case as well, the flavor and quality change with the passage of time, so that a certain period of time elapses. It had been disposed of.

In particular, it has been conventionally said that the prepared food must be kept warm at 80 ° C. or higher. However, when kept at such a temperature, the freshness of the product deteriorates with the passage of time, the odor becomes stronger along with it, the flavor is impaired, and the commercial value is significantly reduced.

[0006] Also, in factories and offices, it is desirable that warm lunches be eaten at meals, but there are problems in manufacturing, and in addition, there are problems in that delivery times are not constant due to traffic congestion. In some cases, the above hopes could not be achieved.

Therefore, if users of factories, offices, etc. can temporarily store these kinds of bento in a hot state, the supplier should deliver them early, avoiding the traffic congestion. In addition to satisfying the user's wishes, the delivery time can be extended on the supplier side as well, so that work efficiency can be improved and cost can be reduced.

[0008] By the way, although a warm storage is required for the temporary warm storage of such bento and prepared foods, the one generally used in the past uses glass wool as a heat insulating material and a heating element. As mentioned above, since the temperature is relatively high above 80 ° C, the odor becomes stronger with the passage of time, and the odor fills the inside of the refrigerator, impairing the flavor, and in extreme cases, Sometimes it became unusable for food.

Under these circumstances, the present inventor has conducted various studies on the above problems, and as a result, it is ideal that the food should be kept warm in the refrigerator at 63 to 68 ° C. If the temperature exceeds 70 ° C., the food should be kept warm. We obtained the finding that it was not done properly. It was also found that when the hot air generated from the heat generator directly contacts the food, the water on the surface evaporates and dries, the humidity changes, and as a result, the quality changes and the flavor is affected.

It has also been found that there are suitable solutions for absorbing odors.

[0011]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems, and by installing and operating the processed food in a predetermined place and storing the processed food in the refrigerator, the taste and material of the processed food are affected. In other words, it is possible to achieve a heat retaining effect and also a deodorizing effect.

[0012]

[Means for Solving the Problems]

 That is, according to the present invention, a cabin formed of a material having good heat conduction is housed in a cabinet containing a heat insulating material with a gap therebetween, and a shelf board can be installed in and out of the cabin. A low-temperature heating element is installed between the cabinet and the cabin, and a far-infrared radiation ceramic sheet having a deodorant effect is attached to the inner wall of the cabinet, and the cabin material is made of stainless steel. In addition, a shutter that can be opened and closed was provided in a part of the cabin, a far-infrared radiation ceramic sheet and a cabin door with deodorant effect were provided inside the door of the cabinet, and low temperature heat generation. It is characterized in that the body is a ceramic fan heater, panel heater, etc. Furthermore, it is constructed so that it can be mounted on a vehicle and uses the radiator's heat dissipation as a low-temperature heating element. And it is characterized in Rukoto like.

[0013]

[Action]

 Hereinafter, a specific configuration of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a partially cutaway front view of the open door of the present invention, FIG. 2 is a transverse sectional view of FIG. 1, and FIG. 3 is a partially cutaway perspective view showing the structure of the refrigerator.

In FIG. 1 to FIG. 3, reference numeral 1 is a box, in which a heat insulating material 2 is incorporated. Reference numeral 3 denotes a cabin installed inside the case 1 with a gap 3 therebetween, which is made of a material having good heat conduction such as stainless steel and is held by four columns 5 which are planted in the case 1. Reference numeral 6 is a low-temperature heating element installed at the bottom of the case 1, which can be used with a domestic power source (100 V AC) such as a ceramic fan heater or panel heater, or an engine of a transportation vehicle when mounted on a transportation vehicle. An appropriate one can be used, such as one that uses the heat radiation of the radiator. Reference numeral 7 is a temperature controller for the low temperature heating element. Further, 8 is a far-infrared radiation ceramic sheet attached to the inner wall of the case 1 and the inside of the door 13 with bolts 12, which serves to absorb the odor generated in the case. Also, stays 9 are fixed to the columns 5 at appropriate intervals so as to face each other, and hold the shelf board 10 in and out. Reference numeral 11 denotes an openable / closable shutter provided on the side surface of the cabin 3, and adjusts the temperature inside the cabin 3 by opening / closing the shutter. Reference numeral 14 denotes a cabin door installed inside the door 13, which is made of the same material as the cabin such as stainless steel. Reference numeral 15 is a hinge that connects the case 1 and the door 13.

Since the present invention refrigerator has the above-mentioned structure, it is installed at a predetermined place, and then a power source (not shown) is connected to the low temperature heating element 6 so that the low temperature heating element 6 When the is heated, the air around it is gradually heated and stored in the void 4. Furthermore, when the difference between the temperature of the low-temperature heating element 6 and the required temperature (63 to 75 ° C) in the refrigerator is about 15 ° C, a temperature difference occurs between the upper part and the lower part of the refrigerator, and the heating element The air heated by 6 rises in the space 4 between the housing 1 and the cabin 3 to heat the cabin 3 from the outside. Therefore, food items such as bento boxes to be kept warm are placed and stored on the shelf plate 10 held by the stays 9 fixed to the support columns 5, and when the door 13 is closed, the cabin 3 is sealed by the cabin door 14. The stored food is indirectly kept warm from the outside of the cabin 3. At this time, the temperature inside the cabin 3 can be adjusted to an appropriate temperature by appropriately opening and closing the shutter 11 provided on the side surface of the cabin 3 together with the temperature controller 7.

Further, since the far-infrared radiation ceramic sheet 8 is attached to the inner wall of the case body 1 and the inside of the door 13 in the storage cabinet of the present invention, the odor generated from food due to temperature rise is It is absorbed by the far-infrared radiation ceramic sheet 8, and the odor does not fill the inside of the refrigerator and does not leak out of the refrigerator.

The far-infrared radiating ceramic sheet in the present invention contains, for example, sintered white porcelain powder and alumina powder as main components, and at least one powder of ferrous oxide, silicon oxide, carbon, magnesia, and silica. It is possible to use a composition containing at least one species and having a peak in the long wavelength region of 7 to 14 microns.

The far-infrared radiation ceramic sheet 8 does not need to be provided on the entire inner wall of the case body 1, but may be about 1/2 of the wall surface and have a thickness of about 1 mm.

Although the principle of the deodorizing effect of the far infrared radiating ceramic sheet 8 is not clear, it is presumed that it is due to ion exchange.

Further, the storage cabinet of the present invention can be mounted on a transport vehicle. In this case, a part of the drainage of the engine radiator is branched off as in the case disclosed in “On-vehicle storage” published in Japanese Utility Model Publication No. 4-31126 filed by the applicant. 1, and the heat can be used as a low temperature heating element.

[0022]

[Effect of device]

 As described above, the present invention has a double structure of a cabinet and a cabin, and warm air is circulated in the space between the cabinet and the cabin to heat the cabin without directly heating the food to be stored. Moreover, since it is kept at a lower temperature than before, it can be kept at an appropriate temperature for a long time and can be used as an edible product without impairing the flavor of the food to be kept warm. Furthermore, it is possible to completely eliminate the odor generated inside the refrigerator. In addition, it can be easily installed by installing it in an appropriate place such as a factory or office. By expanding the delivery time, it is possible to improve work efficiency and reduce costs. And so on, its effect is extremely large.
