Description

[Detailed Description of the Invention] The present invention relates to an electric pot, particularly the structure of a portion of the pot body to which a heating plate and an outer case are attached.

If the body of an electric pot is directly exposed, it is dangerous due to the high temperature.

Therefore, an outer case that surrounds the pot body is generally combined with the pot body.

The outer case may be made of plastic, for example, and may be attached at a distance from the pot body.

By the way, conventionally, the outer case was directly attached to an integrally molded attachment part on the bottom of the pot body.

As a result, the temperature of the outer case becomes quite high, which is undesirable from the viewpoint of causing burns and thermal deformation of the material of the outer case.

The purpose of the present invention is to attach a heating member to the bottom of the pot body and to fix the outer case to this in a state with little thermal influence.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

The electric pot 1 of this embodiment is used for general boiled food or tempura, and is heated by electric heat.

The electric pot 1 can be roughly divided into a pot body 2,
It is composed of an outer case 3, a transparent lid 4, a central lid 5, and a base 6.

The pot body 2 is made of die-casting and has an annular lid holder 7, a brim 8, and a pouring pot 9 on the upper opening edge, and a sheathed heater 10 as a heating element and a heat plate 11 on the lower bottom. Plug receiver 13
, further equipped with a temperature regulator 12 on the side.

The annular lid holder 7 is formed with a low step on the inside at a portion extending outward from the opening edge.

The collar 8 is annular and has an outwardly projecting surface.

The spout 9 is formed by turning a part of the brim 8 and the lid holder 7 into an inverted shape and forming the spout 9 slightly inward and low.

For example, the sheathed heater 10 is bent into a substantially annular shape and is directly buried in the bottom of the pot body 2.

Both ends of the sheathed heater 10 protrude downward from the bottom of the pot body 2, and each end has an L-shaped terminal plate 14.
．． 15 is supported.

The heat plate 11 is formed into a dish-like shape, and is attached to the bottom surface of the pot body 2 using, for example, three setscrews 16 at an angle of 120° around the center.

Furthermore, three case mounting seats 17 and one base mounting seat 18 are fixed to the lower surface of the heat plate 11.

The three case mounting seats 17 are located at intermediate positions between the three setscrews 16, and are arranged at an angle of 120 degrees.

The temperature regulator 12 is attached to the side surface of the pot body 2, and an adjustment knob 42 is fitted into the dial shaft from the outside.

Also, the terminal plate 14 of the sheathed heater 10 is located at the bottom of the pot body 2.
Corresponding to 15, block-shaped plug holder 13 for power intake
is arranged.

This plug receiver 13 is attached to the bottom ridgeline portion of the pot body 2 by combining a support plate 15, a magnetic plate 46, and a mounting screw 47.

The support plate 45 is positioned and fixed to a concave mounting portion 48 raised at the bottom of the pot body 2 with four mounting screws.

The plug receiver 13 is positioned and applied to the support plate 45 from below.

A substantially U-shaped magnetic plate 46, such as an iron plate, is disposed in the groove on the outside of the center of the plug receiver 13.

The mounting screw 47 is loosely inserted into one of the locking holes of the magnetic plate 46 and the through hole of the plug receiver 13.
It then engages with the slotted hole in the support plate 45 and protrudes from the other locking hole in the magnetic plate 46.

The plug receiver 13 is made of an insulator such as porcelain and has two connecting pins 57 facing outward on the left and right sides of the magnetic plate 46.

The surface connection pins 57 are attached to L-shaped terminal plates 58 and 59 on the back of the plug receiver 13, respectively.

The terminal board 59 and the terminal board 15 are connected by a temperature fuse 60.

Further, the terminal plate 58 and the terminal plate 14 are connected to each other by lead wires 61 with the temperature regulator 12 interposed therebetween.

The lead wires 61 are each covered with a heat-resistant cover 64 and secured to the lower surface of the heat plate 11 with a stopper 65.

The pot body 2 is stored inside the outer case 3 at a certain interval.

Therefore, in order to prevent the outer case 3 from deforming inward, the pot body 2 is provided with, for example, four support pieces 66 on its two outer edges.
It is equipped with

This support piece 66 is shaped like a cylindrical shape and is attached to the four outer circumferential surfaces of the pot body 2 with a gap from the outer case 3 using screws 67.

Next, the outer case 3 is made of plastic, for example, into a hemispherical shape, and has a pair of handles 68 on the outer side of its upper edge, and a cover 69 for the temperature regulator 12 and a storage cover 70 for the plug receiver 13 on the side surfaces.

The cover 69 has a transparent window 71 to expose the control knob 42 of the temperature regulator 12 to the outside and to emit the lighting light of the indicator lamp.

The adjustment knob 42 is rotated to turn on and off the power, as well as to set the heating temperature.

The storage cover 70 has a shape that covers the plug receiver 13 and has an insertion window 72 on the outside.

A magnetic plug 73 can be attached to this insertion window 72.

The magnetic plug 73 is in electrical connection with the connecting pin 57, and has a permanent magnet 74 at the center corresponding to the magnetic plate 46.

Further, this storage cover 70 forms a guide portion 75 for positioning at its lower edge.

Furthermore, an outward step 76 and an inner protrusion 77 are formed on the upper edge of the opening of the outer case 3.

The step 76 and the protrusion 77 are provided to prevent tempura oil and the like from entering from the pot body 2.

Since this protrusion 77 corresponds to the lower part of the spout 9, it cannot be formed around the entire circumference.

Therefore, a notch 78 is formed at a position corresponding to the spout 9, and a spacer 80 made of a heat-resistant/insulating material, such as silicone rubber, is inserted into the notch 78 for attachment.

This spacer 80 has a cylindrical shape and closes the space between the notch 78 and the spout 9.

Furthermore, an annular fitting groove 81 and a ventilation window 82 are formed on the bottom surface of the outer case 3, and case mounting plates 83 are provided at three locations on the periphery thereof.

The fixing screws 84 of this case mounting plate 83 are respectively inserted into the case mounting seat 17 of the pot body 2 and the heating plate 11 located inside the outer case 3.

In this way, the pot body 2 is fixed inside the outer case 3 with a certain space that forms the ventilation path 85.

Next, the base 6 is formed into a flat umbrella shape, for example by plastic molding.

A fitting protrusion 86 corresponding to the fitting groove 81 and a recessed guide receiver 87 corresponding to the guide portion 75 are provided on the −L surface of the central portion.

A base mounting hole 88 is bored in the raised part at the center of the fitting protrusion 86, and ventilation holes 9 are formed in the four central parts 89.
Multiple 0's are provided.

Further, on the lower surface of the base 6, legs 91 are provided, for example, at four positions, and a projecting piece 92 lower than the legs 91 is provided on the outside connecting the adjacent legs 91, 91 in the middle.

Note that each of the legs 91 has a non-slip member 93 made of rubber.

Then, the outer case 3 connects the fitting groove 81 on the lower surface to the base 6.
and the guide portion 75 is positioned inside the guide receiver 87 and assembled.

The outer case 3 and the pot body 2 are fixed with one mounting pin 94.

This mounting bolt 94 is inserted upward from the base mounting hole 88 of the base 6, and is inserted into the base mounting seat 18 on the side of the pot body 2.
The base 6 is fixed to the pot body 2 at the lower part of the outer case 3.

On the other hand, the transparent lid 4 is made of transparent heat-resistant glass or the like, and is placed on the lid holder 7 of the pot body 2.

Further, an opening window 95 is provided at the top of the transparent lid 4.
A lid mounting portion 96 is formed on the peripheral edge thereof.

The central lid 5 is removably attached to the lid mounting portion 96.

This central lid 5 is made of, for example, a metal plate, and is provided with a knob 97 at the top.

When energized, the sheathed heater 10 generates heat, the pot body 2 is heated, and heat is applied to the contents.

Even if the pot body 2 reaches a high temperature, the heat is not directly connected to the outer case 3, so the outer case 2 is not thermally adversely affected.

In particular, external air enters through the ventilation hole 90, rises through the ventilation window 82 through the ventilation path 85 between the outer periphery of the pot body 2 and the inner periphery of the outer case 3, and is discharged to the outside over the ridge 77. Therefore, the outer case 3 is constantly being cooled by convection during use.

Further, since the heat at the bottom of the pot body 2 is thermally blocked by the heat plate 11, almost no heat is transmitted to the outer case 3 and the base 6.

However, even in this case, a part of the heat of the pot body 2 is
Set screw 16 Mustard hot plate 11. It is transmitted to a part of the outer case 3, that is, the case mounting plate 83, via the fixing screw 84 and the case mounting seat 17.

Since the locking eagle 16 and the fixing screw 84 are arranged at an angle of 60 degrees with the center part as the center,
At the top, the distance between the set screw 16 and the fixing screw 84 is maximum, and therefore the heat plate 11 receives the cooling action during its heat conduction and releases heat.

In other words, according to this configuration, the amount of heat reaching the outer case 3 through the mustard of the pot body 2 and the hot plate 11 is smaller than when the set screws 16 and fixing screws 84 are installed close to each other. There is.

In addition, in the embodiment, the set screw 16 and the fixing screw 84 are
There are three in each case, but the number is arbitrary.

For example, in the case where there are four setscrews, the set screws 16 and the set screws 84 may be arranged alternately at an angle of 45 degrees.

According to the present invention, the attachment position of the heating plate to the pot body and the attachment position of the outer case to the pot body and the heating plate are arranged alternately and at approximately equal intervals. The amount of heat transmitted can be minimized, and adverse effects such as burns and thermal deformation due to the temperature rise of the outer case can be prevented.
