Abstract

PURPOSE:To prevent the temp. of a top panel from increasing, improve the accuracy of sensitivity to temp., and make the cleaning of a pan easy by a method wherein a hinge part supporting a frame rotatably at one side of a mainbody is installed and at the top panel of the mainbody facing the frame a recessed part is placed and at this recessed part a plate-shaped pan is removably placed with a space. CONSTITUTION:In a nearly lattice-shaped frame 25 installed at the upper part of a top panel 22 spiral heating elements 26, 27 are placed. In a recessed part 38 facing the frame 25 in the panel 22 a plate-shaped pan 39 is placed removably. When a pan is put on the element 26 or 27 and heated, hot air flows out from the ports of the frame 25 by convection and heat is diffused outside and it therefore does not occur that the space between the panel 22 and the frame 25 is filled with heat, and the temp. rise in the inside can be lowered. Further, the accuracy of sensitivity to temp. of a temp. sensor can be increased. Because a space 41 is formed between the pan 39 and the part 38 by projections 40 placed on the pan 39, the temp. of the pan 39 is difficult to be conducted to the panel 22 and the temp. rise in a mainbody 21 can be lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric cooktop having a heating element on the upper part of the main body.

BACKGROUND OF THE INVENTION Conventional electric stoves of this type include, for example, the Japanese Patent Publication No. 61-3
As shown in Japanese Patent No. 1781, it had a structure as shown in FIG.

That is, the sheathed heater 1 is placed on the heater holder 2, the heater holder 2 is placed on the outer edge 4 of the juice tray 3, and the hinge holder is placed on the sheath tube 6 near the terminal 6 of the sheathed heater 1. 7 is firmly fixed, and this hinge metal fitting 7 is fixed to the stove outer peripheral frame 9 via a spring plate 8. Further, a ventilation hole 10 is provided in the center of the juice tray 3, and the end of the heater holder 2 is inserted into the hole 11 provided at the outer edge of the soup tray 3 by the biasing force of the spring plate 8. has been done. Further, a temperature sensor 12 is provided in the center of the sheathed heater 1.
2 detects the temperature of the bottom of the pot placed on the sheathed heater 1 and controls the energization of the sheathed heater 1.

Problems to be Solved by the Invention However, in such a configuration, when a large-diameter pot or the like is placed on the sheathed heater 1, the gap between the bottom of the pot and the outer edge of the soup saucer 3 decreases, and as a result, the vent hole Since the convection of air upward from 1o is reduced, the temperature of the soup pan 3 and the outer frame 9 of the stove become high, increasing the risk of causing burns, or accidentally spilled broth may It was difficult to clean because it was scorched to the outer frame 9 of the stove and was difficult to remove.

In addition, since the convection landscape of air from the vent 1o changes depending on the size of the pot, the ambient temperature of the temperature sensor 12 will also change, and as a result, the temperature sensing performance of the temperature sensor 12 will also be affected by this. As a result, the sensing accuracy of the temperature sensor 12 deteriorates. Furthermore, when a large amount of boiling soup is spilled, the ventilation hole 1o in the center of the soup saucer 3
The boiling liquid would get into the stove itself, and in this case, it would be impossible to clean it, so there was a risk that it would be unsanitary.

The present invention was made in order to solve these problems, and it prevents the temperature of the frame and the top surface of the main body from becoming high,
Furthermore, even if a temperature sensor is installed, the amount of change in the ambient temperature of the temperature sensor can be reduced to improve the accuracy of temperature sensing performance, and the purpose is to provide an electric stove with an easy-to-clean saucer. be.

Means for Solving the Problems In order to solve the above problems, the present invention provides a frame body to which a heating element is attached above the top surface of the main body, and the frame body is rotatably attached to one side of the main body. A pivoting hinge part is provided, a recess is provided in the top surface of the main body opposite to the frame, and a dish-shaped saucer is disposed in the recess with a gap therebetween so as to be detachable.

Effect According to the above configuration, even when a large pot is placed on the heating element and heated, the high temperature air is released through the holes in the frame by convection, so heat is not transferred between the frame and the top of the main body. It becomes difficult for the air to become crowded, and as a result, the rise in temperature of the frame and the top surface of the main body becomes smaller. Also, if you accidentally spill the broth, etc., the broth will drip from the frame onto the saucer, but in this case,
Since the temperature of the saucer is low, it will not burn, and when cleaning, it can be done by rotating the frame and removing the saucer.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, 21 is the main body of the electric stove;
2 is a top surface that covers the upper surface of the main body 21; 23 is a part of the roaster provided within the main body 21; and 24 is a switch operation section provided on the front surface of the main body 21 with an inclination. 26 is the top surface 2
This frame body 25 is a substantially lattice-shaped frame disposed above the frame body 25.
A spiral-shaped heating element 26, 27 is provided.

Reference numeral 28 denotes a hinge portion that rotatably supports the frame 26 at the rear upper portion of the main body 21. Reference numeral 29 denotes a heater receiving fitting for the heating element 26, 27, and a part of the heating element 26, 27 is attached to this heater receiving fitting 29 by hooking, and the frame 2 is attached with a screw 30.
A heater holder 29 is fixed to 5. Reference numeral 30 denotes a temperature sensor, and this temperature sensor 30 is provided at the center of the heating element 26, 27, and is attached to the heater holder 29 by a sensor support fitting 31.

32 is a terminal portion of the heating element 26, and a lead wire 33 is connected to this terminal portion 32 by a terminal screw 34. Also,
The lead wire 33 is inserted into the main body 21 through a burring hole 35 provided near the hinge portion 28 of the top surface 22 and connected to the power supply circuit. A cover 36 covers the terminal portion 32 and the lead wire 33 and has an opening on the lower surface, and is provided integrally with the frame body 26 . 37 is cover 3
This lid body 37 is attached to the cover 36 with screws 3D, and the lid body 37 covers the lower opening of the cover 37.
A heating element 26, a terminal portion 32, and a lead wire 33 are housed in a space formed by the heating element 26 and the lid 37.

Reference numeral 38 denotes a recess provided on the top surface 22 at a position facing the frame 25, and a dish-shaped saucer 39 is removably placed in the recess 38. Also, there are several protrusions 4 on the bottom of the receiver @39.
0 is provided, and when the protrusion 4o comes into contact with the top surface 22, a gap 41 is formed between the bottom and side surfaces of the saucer 39 and the recess 38 of the top surface 22.

The operation of the above configuration will be explained next.

When a pot is placed on the heating element 26 or 27 and the heating element 26 or 27 is energized to heat the pot, the ambient temperature near the heating element 26 or 27 rises, and air is pumped through the hole in the frame 25 by convection. Since the high-temperature air flows out and the heat is dissipated to the outside, heat is no longer trapped between the top surface 22 and the frame 25, and as a result, the inside of the top surface 22, the frame 25, and even the main body 21. It is possible to reduce the temperature rise. Furthermore, since the ambient temperature of the temperature sensor 30 can also be lowered, changes in the ambient temperature due to the size of the pot, etc. can be reduced, and as a result, the temperature sensing accuracy of the temperature sensor can be improved.

Further, if the broth is accidentally spilled during cooking, the broth passes through the holes in the frame 25 and drips onto the saucer 39, where it accumulates. When cleaning, rotate the frame 26 upward about the hinge part 28 and place the saucer 39 in the recess 3 of the top surface 22.
By taking it out from the tray 8, the tray 39 can be washed with water, and as a result, the tray 39 can be easily cleaned.

Moreover, since a gap 41 is formed between the saucer 39 and the recess 38 of the top surface 22 by the protrusion 40 provided on the saucer 39, the temperature of the saucer 39 is difficult to be conducted to the top surface 22, and as a result, This makes it possible to reduce the temperature rise within the main body 21.

When the heating element 26 or 27 breaks down due to disconnection or the like and the heating element 26 or 27 is replaced, the frame 26 or 27
The lead wire 33 of the heating element 26 or 27 can be easily removed by rotating the terminal, removing the screw 37', removing the lid 37, and then removing the terminal screw 34 of the terminal portion 32. The heating element 26 or 27 can be easily replaced. Even if water is accidentally dropped above the terminal section 32, since the terminal section 32 is covered by the cover 36, there is no risk of water splashing onto the terminal section 32, which is extremely safe.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
Even if you place a large pot on top of the heating element and heat it, the hot air will be released through the holes in the frame by convection.
Heat is less likely to accumulate between the frame and the top of the main body, and as a result, the temperature rise of the top of the main body and the frame is small, so there is no risk of burns, increasing safety. If a temperature sensor is installed, its temperature sensing performance can also be improved, making it possible to control the heating element with high precision.As a result, excellent automatic cooking becomes possible and the effort of cooking can be reduced. can.

If boiling liquid, etc. still boils over, it will accumulate on the saucer, and in this case, the saucer can be easily attached and removed, so this saucer can be washed with water, and as a result, the top surface can always be kept clean. It is what it is.
