Description

[Detailed description of the invention] This invention relates to the improvement of a food warmer used to keep foods such as boxed lunches, eel bowls, steamed buns, shumai, and milk warm.

Conventional food warmers have an electric heating element installed at the bottom of the warmer body, with a sealed space heater, etc., covered by a protective plate in the center on the mounting plate, and installed at the bottom of both sides of the protective plate. It was formed so as to be fixed to the attached mounting piece through screws (for example, Japanese Utility Model Publication No. 5252298).

As a result, the electric heating element cannot be removed from the body of the heat insulator, making it difficult to repair the electric heating element when it breaks down, and to remove dust that has accumulated on the electric heating element.
Not only is it extremely troublesome and unsanitary to clean up lumps, water drops, food juices, etc., but it is also difficult to fix the electric heating element in the body of the heat insulator, and the electric heating element often breaks down, making it uneconomical. Met.

In addition, a copper plate was placed opposite to the bottom of the shelf board for placing food such as lunch boxes, which was provided at appropriate intervals above the electric heating element in the main body of the heat insulator, and on both lower side walls between the electric heating element. It was formed so that a net plate was placed on each copper plate (for example, Japanese Utility Model Publication No. 19806/1983).

Therefore, not only is the structure of the net plate part complicated,
The distance between the electric heating element inside the heat insulator body and the lowest shelf board must be set wide.

This idea was devised in order to eliminate the above-mentioned drawbacks, and the rails are installed opposite each other on the lower side walls of the heat insulator body, which has a door hinged to the front road. , on the other hand, a front plate having protrusions on the left and right edges of the front plate, a mounting plate fixed to the lower part of the rear face of this front plate, and an insulator placed approximately at the center of the mounting plate. 0 consisting of an enclosed space heater mounted at least so as to be covered by a protective plate;
The electric heating body is formed into a pull-out type so that each protrusion of the front plate can be attached to the front side of both side walls of the heat insulator body by means of screws, etc., on each rail in the heat insulator body. In addition to being removably inserted, several pairs of shelf support plates are provided vertically facing each other at appropriate intervals on both side walls above the electric heating element in the heat insulator main body, and each pair of shelf support plates is placed on each opposing shelf support plate. The electric heating element can be pulled out by installing several shelves that can be inserted and removed, each with a heat hole in the center, and attaching a mesh plate to the bottom of the heat hole on the bottom shelf. In addition to making it extremely easy to repair the electric heating element when it breaks down and cleaning the electric heating element,
It is hygienic, has low manufacturing costs, and is economical as there are fewer failures of the electric heating element.Furthermore, the structure of the net plate part is simple, and the distance between the electric heating element and the bottom shelf board can be set narrowly. This not only makes it possible to significantly downsize the main body of the heat insulator, but also ensures excellent safety by preventing rubber bands, chopsticks, wrapping paper, etc. from falling from the heating holes to the electric heating element below. This product provides a food warmer with a high temperature.

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

As shown in the figure, a heat insulator main body 4 filled with a heat insulating material 3 is formed inside an outer box 1 and an inner box 2, and a door 5 is hinged to the road portion of the front surface of this insulator main body 4. A drawer-shaped electric heating body A is removably inserted in a drawer type on rails 6 each having an inverted cross section and provided oppositely to each other on both lower side walls and the rear wall of the heat insulator main body 4.

This electric heating body A includes a middle plate 8 in which backward-facing bent pieces 7 are provided on the left and right side edges, a back plate 9 fitted into the rear surface of the middle plate 8 excluding the lower part, and a middle plate 8. The heat insulator main body 4 is fitted externally from the front side, has backward-facing bent pieces 10 on the upper and lower side edges, and protrusions 11 with screw holes for screwing onto the front sides of both side walls of the heat insulator main body 4 on the left and right side edges, respectively. A front plate 13 consisting of a front plate 12 having
On the lower surface of the back plate 9 on the rear surface of the front plate 13, a mounting plate 15 is provided with upwardly bent pieces 14 on the left and right rear edges, respectively.
On the insulator 16 laid approximately at the center of the mounting plate 15, a lead wire 19 and a conductive plate 20 are connected from the cord insertion port 17 and the switch 18 attached to the front plate 13.
a closed space heater 21 connected via;
A pyramid-shaped protection plate 22 with an open top and bottom that covers and protects the closed space heater 21 is formed so as to be screwed to the periphery via several mounting pieces 23 and 24, respectively. has been done.

25 is a temperature adjustment bar whose base end is directly connected to the temperature adjustment knob 26 of the front plate 13 and whose tip is supported by the support plate 27; 28 is a lead wire from the temperature adjustment bar 25 and the switch 18; This is a fuse mounting plate for mounting the fuse connected to No. 29.

In addition, several pairs of shelf plates 30 having an inverted cross-section are disposed on both side walls above the electric heating element A in the heat insulator main body 4 so as to face each other in the vertical direction at appropriate intervals. On the shelf support plate 30, a square or circular heat hole 31 is bored in the center of the square plate, and a rising piece 32 is folded around the periphery of the square plate and the heat hole 31. A number of shelf boards 33 made up of the above are placed in a removable manner, and only the lowest shelf board 33 is fixed, and a metal net plate 34 is attached to the lower surface of the heat passage hole 31. Attach.

Furthermore, a reinforcing plate 35 having a box-shaped cross section is vertically fixed to the center portion of the rear wall in the left and right direction in the heat insulator body 4, and several reinforcing plates 35 are fixed to the rear wall and both sides below the electric heating element A of the heat insulator body 4. ventilation holes 36 are bored.

Since this invention is configured as described above, the heat insulator main body 4
By attaching the mesh plate 34 to the bottom surface of the heat-conducting hole 31 of the lowest shelf board 33 in the interior, not only does the conventional copper plate become unnecessary, but the mesh plate 34 is much smaller than the conventional one. Because of this, the structure of the net plate part is extremely simple, and electric heating element A
Since the distance between the heat insulator main body 4 and the lowest shelf board 33 can be set narrower than before, the size of the heat insulator main body 4 can be significantly reduced.

In addition, when foods such as lunch boxes are placed on each shelf board 33, even if rubber bands, chopsticks, wrapping paper, etc. fall downward from the heat ventilation holes 31 of the top shelf board 33, The net plate 34 attached to the lower surface of the heat passage hole 31 of the lowermost shelf board 33 can reliably prevent the shelf board 33 from falling to the electric heating element A below, resulting in extremely high safety.

Moreover, on each rail 6 provided opposite to the lower side walls etc. in the heat insulator main body 4, a drawer shape is provided from the front plate 13, the mounting plate 15, the sealed space heater with a protection plate 22, etc. 21. By inserting and removing the electric heating element A in a drawer type, the electric heating element can be easily pulled out from inside the heat insulator body 4, so it can be repaired when the electric heating element A breaks down, and it can be easily inserted and removed. It is extremely easy to clean accumulated dirt, scum, water droplets, food juices, etc.

In addition, since the electric heating element A is inserted and removably inserted into the heat insulator main body 4, when inserting the electric heating element A onto each rail 6 in the heat insulator main body 4, both sides of the heat insulator main body 4 can be inserted. Since it is only necessary to attach each projecting piece 11 of the front plate 13 to the front of the wall with screws or other means, it is not necessary to insert the electric heating element A into the heat insulator body 4 or to separate the electric heating element A and assemble it separately. As a result, the assembly operation of the electric heating element A is extremely simple and the manufacturing cost can be reduced, and since the electric heating element A can be pulled out and cleaned easily, there are fewer failures of the electric heating element A. It is extremely economical.

Furthermore, not only the electric heating element A but also each of the shelf boards 33 except the lowest shelf board 33 can be pulled out and cleaned easily, so that the parts of the heat insulator that are particularly easily soiled can be kept sanitary at all times.

As explained above, according to this invention, it is extremely easy to repair the electric heating element when it breaks down, to clean the electric heating element, etc., and also because the manufacturing cost is low and the number of failures of the electric heating element is small. It is economical, and the areas that are particularly prone to dirt can be kept sanitary at all times. Furthermore, the structure of the net plate part is simple, and the main body of the heat insulator can be significantly downsized. Various effects such as extremely excellent safety can be obtained by reliably preventing falling from the heating hole to the electric heating element below.
