Description

[Detailed explanation of the invention] [Field of industrial application] This invention relates to electric stoves, and in particular,
This invention relates to improvements in a soup tray provided below a heater unit of an electric stove and a support structure for the soup tray and the like.

[Conventional technology]

To explain the structure of a conventional electric stove, as shown in FIG. 2, which is an enlarged vertical cross-sectional view showing the main parts of the stove, a sheathed heater 1 formed in a spiral shape is fixed at the center by a support fitting 2. They are supported to form a heater unit 3, which is mounted on the outer ring 20. The juice receiving guide plate 21 has a funnel shape and is attached to the outer shell case 22 so as to cover the outer ring 20 from below, and a juice receiving tray 24 is provided in the outer shell case below the outlet 23 at the bottom of the guide plate 21. There is. The outlet portion 25 of the heater unit 3 passes through the juice receiving guide plate 21 and is pulled out laterally.

It is well known that electricity can be supplied to the heater unit through the outlet 25 and cooking can be performed using the heat generated by the heater unit.

[The problem that the idea attempts to solve]

Conventional electric stoves are constructed as described above, so when boiling over, first pull up the sheathed heater 1, then remove the outer ring 20 and the soup receiving guide plate 2.
1 and then take out the soup tray 24 to throw away the accumulated boiled juice, which is a problem in that it is very troublesome to dispose of it. There were also other problems, such as it being difficult to check how much boiled soup had accumulated in the soup tray while the electric stove was in use.

This idea was created in view of the problems mentioned above. When boiling over boils, it is easy to check how much boiled liquid has accumulated, and it is easy to remove the detachable parts when cleaning the liquid and solids from the liquid. The purpose is to obtain an electric stove that is easy to clean and is easy to clean.

[Means to solve the problem]

The electric stove according to this invention includes a heater unit formed by fixing a sheathed heater formed in a spiral shape with a support metal fitting, and a guide surface that is concentrically placed on the upper surface and slopes downward toward the periphery. and an annular recessed portion having a rising edge on the inner periphery that is fitted and locked to the inner circumferential surface of the peripheral edge of the juice receiving plate. and an upper plate that covers the upper opening of the outer shell case and rests on the outer shell case; A ring-shaped trivet whose inner periphery is positioned so as to circumscribe the outer periphery of the support fitting, and a heat shield plate located on the outer periphery side and having air holes and provided directly below the liquid receiving plate. It is.

[Effect]

In this invention, the liquid receiving plate has a guide surface that slopes downward toward the outer peripheral edge, which acts to guide boiled liquid to the peripheral edge and collect it in the recessed part of the upper plate. The boiled liquid that accumulates in the concave part of the upper plate is less likely to cause scorching because this concave part is located far from the sheathed heater, and is stopped by the rising edge formed on the inner periphery of the concave part of the upper plate. Therefore, it is easy to remove and clean the boiled liquid. Furthermore, radiant heat from the sheathed heater to the inside of the outer shell case is blocked by the heat shield plate, so that the boiled liquid will not burn due to the heat transferred from the outer shell case to the upper plate. Furthermore, a portion of the cooling air that has passed through the air holes in the heat shield plate rises along the inclined liquid receiving plate, and the liquid receiving plate is cooled by the cooling air at that time.

〔Example〕

This invention will be described in detail below with reference to the illustrated embodiments.

In the electric stove according to this invention, as shown in FIG. It is placed on the juice receiving plate 4. A juice receiving plate 4 located concentrically with the sheathed heater 1 directly below the heater unit 3
has an upper surface that slopes downward from the ventilation hole 5 in the center toward the peripheral edge 6 and serves as a guide surface 4a for boiled liquid, and supports the outer periphery 2a of the support fitting 2 near the peripheral edge of this upper surface. There is. The juice receiving plate 4 has its ventilation hole 5
is covered with a cover plate 7 located at the center of the heater unit, and its peripheral edge 6 is supported by an upper plate 9 that covers the upper opening of the outer shell case 8 of the electric stove and rests on the outer shell case 8. There is. That is, the upper plate 9 has an annular recess 10 formed near its outer periphery, and the recess 1
0 is placed on the outer shell case 8, and the rising edge 10a formed on the inner periphery of the recessed part 10 fits into the inner peripheral surface of the peripheral edge 6 of the liquid receiving plate 4. By doing so, the juice receiving plate 4 is supported. Furthermore, a plurality of protrusions 11 are provided within the recessed portion 10.
are formed on the same circumference at intervals in the circumferential direction,
A trivet 12 is placed on these projections 11.
The trivet 12 has an annular shape, and its lower end edge 12a is placed on the projection 11, and its upper end inner periphery 12b is in circumscribed contact with the outer periphery 2a of the support fitting 2, so that the heater unit 3
placed concentrically outside of. Lower edge 12 of trivet 12
a rests on the protrusion 11, so the lower edge 12
A gap 13 is formed between a and the bottom surface of the recessed portion 10. Directly below the juice receiving plate 4, a heat shield plate 14 that covers the center opening of the upper plate 9 is attached to the upper plate.
has a plurality of air holes 14a.

In the electric stove configured as described above, when the sheathed heater 1 is energized, it heats the pot etc. on it and at the same time the soup receiving plate 4 is also heated by radiant heat, but the outer shell case 8 Cooling air due to natural convection rises from the air hole 8a and the air hole 14a along the inclined liquid receiving plate 4 and is discharged from the ventilation hole 5, so that the inclined liquid receiving plate 4 produces the so-called "enttsu effect". Since active convection occurs on the back surface of the juice receiving plate 4 and the juice receiving plate 4 is efficiently cooled, overheating of the juice receiving plate 4 is prevented. On the other hand, radiant heat into the outer shell case 8 is blocked by the heat shield plate 14.

If boiling over occurs under such usage conditions, the ventilation hole 5 provided in the soup receiving plate 4 is covered by the lid plate 7, so that the boiling over will not leak into the interior. All of the boiled soup is transmitted to the guide surface 4a of the soup receiving plate 4, passes through the peripheral edge 6, and is evenly collected in the soup receiving recess 10 through the gap 13. At this time, the concave portion 10 is particularly provided below the outer periphery away from the sheathed heater 1 and is less affected by heat. Since the formed rising edge 10a fits into the inner circumferential surface of the peripheral edge 6 of the soup receiving plate 4, boiled soup does not flow into the inside of the stove. Therefore, after cooking, boiled-over soup can be easily cleaned and removed by simply removing the trivet 12 without removing the heater unit 3 and the soup receiving plate 4. Furthermore, the radiant heat from the sheathed heater 1 to the inside of the outer shell case 8 is blocked by the heat shield plate 14, so that the components inside the outer shell case 8 are not affected by the heat, and from the outer shell case 8 to the upper plate 9. The heat transferred to the boiled liquid will not cause it to burn. Furthermore, convection is actively occurring on the back surface of the juice receiving plate 4, and the juice receiving plate 4 is efficiently cooled.
The boiled liquid will not burn.

[Effect of idea]

As described above, according to this invention, a liquid receiving plate having a guide surface sloping downward toward the peripheral edge and having a ventilation hole formed in the center is provided directly below the heater unit, and The part is engaged with the inner periphery of a concave part provided near the outer periphery of the upper plate, and the trivet is mounted on the concave part via the protrusion, and air is provided on the outer periphery side directly below the liquid receiving plate. Since a heat shield plate with holes is provided, all boiled liquid collects in the recessed part, and the extent of the accumulation can be visually checked even when the stove is in use. In addition, it can be cleaned simply by removing the trivet, and the accumulated boiled liquid does not cause scorching, making it easy to clean. Furthermore, due to the so-called Entsu effect of the juice receiving plate, the juice receiving plate is efficiently cooled by the cooling air, so that the juice does not get scorched on the juice receiving plate, and the juice is smoothly guided to the recessed part, and it maintains its aesthetic appearance for a long time. It also has the effect of being superior.
