[0004] Next, as shown in FIG. 4, a middle box 15, a heating heater 16, a power switch 17, and a heat insulating material 18
, Snowboard 19, water pan 20, body packing 21
, Door packing 22, door 23, upper hinge 24,
This is a bento electric refrigerator 27 equipped with a lower hinge 25, which can be variably heated up to a temperature of approximately 63 ° C. to 75 ° C. in the refrigerator 27, and which is provided with a temperature fuse 110 ° C. and 6A to prevent overheating.

[0005]

However, in the above-described lunch box electric warmer 27 of the prior art, since the heater (resistance wire) 16 is provided on the outer surface of the inner box 15,
Heating may take longer than necessary.

In addition, it is difficult to easily take out the lunch box from the inside of the storage 27, and there is no safety sensor for the heating power supply 17 because a weight sensor for the lunch box is not provided.

The present invention has been made in view of the above circumstances, and has as its object to provide a structure in which an elderly household can easily heat a lunch box and easily take out the lunch box from the storage 12. An object of the present invention is to provide a bento electric refrigerator 12.

[0008]

According to the present invention, in order to achieve the above object, as shown in FIG. 1, for example, when the door 8 of the bento electric refrigerator 12 is opened, the inner plate 11 automatically slides. Power switch 4 after keeping warm and taking out lunch by the structure and easy to take out
If you forget to turn off the power, the sensor 3 automatically turns off the power switch 4, adopts the heat insulating material 6, and changes the heating and keeping the temperature to about 30 ° C. to 90 ° C. as you like. It is characterized by being provided inside.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In this invention, when the door 8 of the storage 12 is opened, the inner plate 11 is automatically slid 5 so that the elderly household can easily handle the bento electric storage 12. It is easy to take out, and the heat insulation and the power switch 4 are turned on and off by the lunch box weight sensor 3,

Further, by providing the heating heater 2 inside the inner box 1 in order to continuously heat and keep the inside of the refrigerator 12 as desired, the efficiency has been improved and the cost has been greatly reduced. Things.

[0011]

1 and 2 show an embodiment of the present invention.
This will be described in detail based on (a) and (b).

[0012]

First Embodiment FIG. 1 is a schematic view showing an embodiment of a lunch box electric refrigerator 12 according to an embodiment of the present invention.

As shown in FIG. 1, the lunch box electric warmer 12 is provided with a heating heater 2 inside the inner box 1, and can turn on and off the heat insulation and power switch by the lunch box weight detecting sensor 3. When the door 8 of the refrigerator 12 is opened, the inner tray 11 slides automatically 5 and has a structure that makes it easy to take out. Further, the water tray 8 and the heat insulating material 6 are provided. Insulation is about 30 ° C-90
This is a lunch box electric warming storage 12 of the present invention which can be changed to up to ° C.
Is provided inside the inner box 1 so that the cost can be greatly reduced.

Next, as shown in FIG. 2A, the resistance wire 9 of the heater 2 for heating and keeping the inside of the lunch box electric storage 12 is provided inside the inner box 1, and the lunch box inside the inner box 1 is provided. Is to be heated.

Next, in FIG. 2B, a sheath heater 10 is used for the heater 2 used inside the inner box 1,
The lunch box inside the inner box 1 is heated.

[0016]

As described above, according to the bento electric refrigerator 12 of the present invention, the structure in which the inner plate 11 is easily slid and automatically taken out 5, the lunch box weight sensor 3 is provided, and the heater 2 in the refrigerator 12 is provided. By providing a structure in which the lunch box inside the inner box 1 can be heated by being provided from the outer surface of the inner box 1, the elderly household can be easily handled, and safety can be ensured, and the efficiency is improved.
