Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric stove having a heating element on an upper part of a main body.

2. Description of the Related Art A conventional electric stove of this type is disclosed in, for example, Japanese Patent Publication No. 61-3.
As shown in Japanese Patent No. 1781, the structure was as shown in FIG.

That is, the sheath heater 1 is placed on the heater receiving metal fitting 2, the heater receiving metal fitting 2 is placed on the outer edge 4 of the juice receiving tray 3, and the hinge metal fitting is attached to the sheath pipe portion 6 near the terminal 5 of the sheath heater 1. 7 is fixed, and this hinge fitting 7 is fixed to the stove outer peripheral frame 9 via a spring plate 8. Further, a vent hole 10 is provided in the central portion of the juice receiving tray 3, and the end of the heater receiving metal fitting 2 is inserted into the hole 11 provided in the outer edge of the juice receiving tray 3 by the urging force of the spring plate 8. ing. A temperature sensor 12 is provided at the center of the sheath heater 1.
Reference numeral 2 detects the temperature of the bottom of the pan placed on the sheath heater 1 and controls the energization of the sheath heater 1.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in such a configuration, when a large-diameter pot or the like is placed on the sheath heater 1, the gap between the bottom of the pot and the outer edge of the juice tray 3 is reduced, and as a result, the vent hole is formed. Since the convection of air upward from 10 is reduced, the temperature of the soup saucer 3 and the stove outer peripheral frame 9 becomes high, which increases the risk of causing burns or the like, or spilled juice accidentally spilled on the soup saucer 3 or It was difficult to clean because the outer peripheral frame 9 of the stove was scorched and difficult to remove.

Further, since the counter flow rate of air from the ventilation hole 10 changes depending on the size of the pan, the ambient temperature of the temperature sensor 12 also changes, and as a result, the temperature sensing performance of the temperature sensor 12 is also affected by this. Therefore, the temperature sensor 12 has a disadvantage that the sensing accuracy is deteriorated. Further, when a large amount of broth is spilled, the vent hole 10 in the center of the soup saucer 3
The broth would further invade the stove body, and in this case, cleaning could not be performed, which could result in unsanitary conditions.

The present invention has been made to solve such a problem, and prevents the temperature of the top surface of the frame body and the main body from becoming high,
Even if a temperature sensor is provided, the amount of change in ambient temperature of the temperature sensor can be reduced to improve the accuracy of temperature sensing performance, and the top surface of the main body can be easily cleaned and the heating element can be easily replaced. The purpose is to provide an electric stove with excellent serviceability.

Means for Solving the Problems In order to solve the above problems, the present invention provides a substantially lattice-shaped frame body to which a heating element is attached above the top surface of the main body, and above the terminal portion of the heating element. A cover that is provided integrally with the frame body and that covers the terminal portion and the lead wire connected to the terminal portion is provided, and a lid body that covers the lower surface opening of the cover is provided below the terminal portion, and A hinge portion that pivotally supports the frame body on one side of the main body is provided, and the lead wire is inserted into the main body from the vicinity of the hinge portion.

Action According to the above configuration, even when a large pot is placed on the heating element and heated, the heated air is discharged by convection from the space of the substantially lattice-shaped frame body, and thus the top surface of the frame body and the main body. In the meantime, heat is less likely to be accumulated, and as a result, the temperature rise on the top surfaces of the frame body and the main body is reduced. Also, when spilled spilled liquid is accidentally spilled, spilled liquid will drop from the frame onto the top surface of the main body.In this case, the temperature of the top surface of the main body is low, so there is no burning, and cleaning is done. When rotating the frame, you can easily wipe off the top surface of the main body without obstacles such as electrical connection lines of the heating element and other protrusions by rotating the frame. Even when replacing, the frame can be easily rotated by rotating the frame and removing the lid, thereby providing an electric stove with excellent serviceability.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 to 3, reference numeral 21 denotes a main body of an electric stove, 2
Reference numeral 2 is a top surface that covers the upper surface of the main body 21, 23 is a roaster portion provided inside the main body 21, and 24 is a switch operation portion that is provided on the front surface of the main body 21 with an inclination. 25 is the top surface 2
2 is a substantially lattice-shaped frame body arranged above the frame 2.
Are provided with spiral heating elements 26 and 27.
Reference numeral 28 denotes a hinge portion that rotatably supports the frame body 25 on the upper rear portion of the main body 21. Reference numeral 29 denotes a heater receiving metal fitting for the heating elements 26, 27. The heater receiving metal fitting 29 is attached to a part of the heating element 26, 27 by biting, and the heater receiving metal fitting 29 is fixed to the frame body 25 with a screw 29a. Reference numeral 30 denotes a temperature sensor. The temperature sensor 30 is provided in the central portion of the heating elements 26 and 27, and is attached to the heater receiving fitting 29 by the sensor support fitting 31.

Reference numeral 32 denotes a terminal portion of the heating element 26, and a lead wire 33 is connected to the terminal portion 32 by a terminal screw 34. Further, the lead wire 33 is inserted into the main body 21 through a burring hole 35 provided in the vicinity of the hinge portion 28 of the top surface 22 and connected to the power supply circuit. 36 is a cover that covers the terminal portion 32 and the lead wire 33 and has an opening on the lower surface.
It is provided integrally with the frame body 25. Reference numeral 37 is a lid that covers the lower opening of the cover 36. The lid 37 is attached to the cover 36 with screws 38, and the terminal portion of the heating element 26 is placed in the space defined by the cover 36 and the lid 37. 32
And the lead wire 33 is stored.

Next, the operation of the above structure will be described. Heating element 2
Place the pot on 6 or 27, and the heating element 26 or 27
When the pan is heated by applying electricity to the heating element 26 or 27
The ambient temperature in the vicinity rises, high-temperature air flows out from the space of the frame body 25 by convection, and heat is dissipated to the outside, so that heat is not trapped between the top surface 22 and the frame body 25, and as a result, , The top surface 22 and the frame 25, and further the main body 2
It is possible to reduce the temperature rise inside 1. Further, since the atmosphere temperature of the temperature sensor 30 can also be lowered, the change of the atmosphere temperature due to the size of the pan or the like can be reduced, and as a result, the temperature sensing accuracy of the temperature sensor can be improved.

In addition, when the simmered juice is accidentally spilled during cooking, the broth falls on the top surface 22 and collects on the top surface 22.
Since the temperature is low, the broth does not burn, and since the frame 25 can be easily rotated upward about the hinge portion 28, the spilled spilled on the top surface 22 can be easily wiped off. It is possible to maintain cleanliness.

Further, the lead wire 33 for energizing the heating element 22 is inserted into the main body 21 through the burring hole 35 provided near the hinge portion 28. Therefore, even if the frame body 25 is rotated, the lead wire 33 is turned on. Since the bending angle of the lead wire 33 is small, the lead wire 33 is hard to be broken, and its durability is excellent. Further, since the lead wire 33 is covered with the cover 36 and the lid body 37, it does not come into contact with boiling water and does not interfere with wiping the top surface 22.

When the heating element 26 or 27 fails due to disconnection or the like and the heating element 26 or 27 is replaced, the frame 25 is rotated, the screw 38 is removed, the lid 37 is removed, and the terminal portion 32 is further removed. Since the lead wire 33 of the heating element 26 or 27 can be easily removed by removing the terminal screw 34 of the heating element 26 or 27, the heating element 26 or 27 can be easily replaced. Even if water is accidentally dropped above the terminal portion 32, since the terminal portion 32 is covered by the cover 36, there is no risk of water splashing on the terminal portion 32.
It's extremely safe.

Effects of the Invention According to the present invention, as is clear from the description of the above embodiments,
Even when a large pot is placed on the heating element to heat it, the hot air is released by convection from the space of the substantially lattice-shaped frame, so heat does not easily accumulate between the frame and the top surface of the main body. As a result, the temperature rise of the top surface of the main body and the frame is small, so there is no risk of burns and safety can be improved, and if a temperature sensor is provided, the temperature sensing performance should also be improved. As a result, it is possible to control the heating element with high precision, and as a result, excellent automatic cooking can be performed and cooking time can be saved. Also, even if you spill the broth on the top of the body, the temperature of the top is low, so the broth will not burn,
Moreover, since this broth can be easily wiped off by rotating the frame, the broth can always be kept clean. Further, there is little fear that the lead wire will be broken due to the rotation of the frame body, and the reliability can be improved. And
According to the present invention, there is no risk of boiling liquid or the like on the heating element terminal portion or the lead wire portion, and the cleaning performance can be improved without disturbing the top surface of the heating element. When you want to replace the heating element if it breaks down, you can easily replace the heating element by rotating the frame, removing the lid that covers the lower part of the heating element terminal, and removing the lead wire from the terminal.
