Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric cooker that heats the inside of the refrigerator to cook food.

Conventional technology Conventional electric cookers of this type include, for example, the
As shown in Publication No. 3395, it had a structure as shown in Figure 2.

That is, a heater 3 is attached to a lid 2 that covers the upper opening of the cooking device main body 1, a glass window 4 is provided at the center of the top surface of the lid 2, and one end of the glass window 4 is connected to the hole end surface 5 of the lid 2. and the other end was supported by a metal fitting 6.

Problems to be Solved by the Invention However, with such a structure, when observing the cooking state during cooking, it is ideal because it can be seen from the top, but when the heater 3 is heated with electricity, Since the heat above the heater 3 is radiated directly to the lid 2 and the glass window 4, not only does the heat loss from the lid 2 increase, but the lid 2 becomes extremely hot, which is dangerous, and it is dangerous to attach it to the lid 2. There was a risk that the heat resistance temperature of the handle 7 and the glass window 4 would be exceeded.

In view of these current circumstances, this invention not only allows you to observe the cooking status from the top while cooking, but also enables economical heating with little heat loss to ensure uniform internal temperature. The object of the present invention is to provide an electric cooker that can prevent the food from becoming abnormally high temperature.

Means for Solving the Problems In order to solve the above problems, the present invention provides a reflective plate between the upper heater and the top surface of the lid, this reflective plate covers the entire heat generating part of the upper heater, and A hole with approximately the same size as the glass window is provided in the center.

According to the above configuration, when the upper heater is heated by electricity, the radiant heat upward from the upper heater is reflected by the reflector that covers the heat generating part of the upper heater and poured onto the food to be cooked, resulting in efficient cooking. I can do it. During this cooking process, radiant heat is not directly poured into the top glass window of the lid, so it is prevented from reaching an abnormally high temperature, and therefore does not exceed the heat-resistant temperature. Also, while cooking, you can see the food you are cooking from the top through the glass window and the perforated part of the reflector, so you won't make any mistakes.Furthermore, there is little heat dissipation in the center of the cooking cabinet.
Normally, the temperature is high, but the perforated portions of the reflector and the glass window dissipate the heat appropriately, resulting in a uniform temperature distribution.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIG. 1, reference numeral 8 denotes a cooking device main body, and this cooking device main body 8 is equipped with a pot-shaped container 9 inside, and its side surfaces are covered by an outer shell 10. 11 is a lower heater, which is integrally attached to the container 9. 12 is a temperature controller, this temperature controller 11 is arranged at the bottom of the container 9,
variably controls the temperature of the 13 is the outer shell 10
It is an operation panel attached to the
4. Install the changeover switch 15. 16 is a handle for carrying the cooking device main body 8. A lid 17 is placed to cover the upper opening of the cooking device main body 8, and a glass window 18 made of tempered glass or the like is provided at the center of the top surface of the lid 17. This glass window 18 is pressed and fixed to the flange hole 19 of the lid 17 via a ring-shaped packing 20 by a part of the lid handle 21 and a part of the support base 23 that covers the air hole 22. has been done. This configuration reliably prevents smoke and steam from leaking from around the glass window 18, and also prevents conductive heat from directly transferring from the lid 17 to the glass window 18, thereby preventing the glass window 18 from becoming hot. At the same time, it also prevents the lid handle 21 and the supporting portion of the glass window 18 of the support base 23 from becoming hot. 24 is an upper heater, and a heater pottery 25 made of porcelain is attached to the terminal part of the upper heater 24, and a heater metal fitting 26
The heater pottery 25 and the upper heater 24 are securely fixed. Reference numeral 27 denotes a reflector, which has a flange portion 28 at its outer peripheral end so as to wrap around the upper heater 24, and has a support pottery 29 at one end for supporting the reflector 27. A perforated portion 30 is formed in the center so as to correspond to the glass window 18. If the diameter of the perforated portion 30 is set to be equal to or smaller than the inner diameter of the packing 20, direct radiant heat to the packing 20 can be avoided, thereby preventing the temperature of the packing 20 from rising. Also, this reflector 27 is connected to the upper heater 24.
It is removably attached to the upper heater 24 by lifting it with a hanging fitting 31 and attaching it to the claw part 32 of the heater fitting 26. The upper heater 24 and the reflector 27 are connected to the heater insertion opening 33 of the lid 17.
Insert the heater pottery 25 into the insertion opening 3, hook the support pottery 29 onto the support fitting 34 of the lid 17, and insert the clip 35 rotatably provided on the heater pottery 25 into the insertion opening 3.
By pressing it against the 3 side, it is supported removably and reliably. Since the heater insertion port 33 is configured to protrude toward the inside of the lid 17, water vapor condenses and water droplets adhering to the inside of the lid 17 enter the terminals of the upper heater 24, deteriorating the insulation. can be reliably prevented, and the lid 1
7, the heater insertion port 33
This prevents water droplets from flowing outside. 3
6 is a cord for supplying power to the upper heater 24,
A commonly used instrument plug 37 is attached to one end of the cord 36. 38 is a rack on which the food to be cooked is placed, and 39 is a leg of the cooking device main body 8.

The operation of the above configuration will be explained next.
The food to be cooked is placed on the rack 38, and the lid 17 with the upper heater 24 attached is placed on the cooking device main body 8. Then, when the appliance plug 37 of the cord 36 is inserted into the upper heater 24 and the power is turned on, the upper heater 24 is energized and heated to raise the temperature inside the refrigerator. The upward radiant heat of the upper heater 24 is reflected by a reflecting plate 27 provided to cover the heat generating portion of the upper heater 24 and radiated toward the food to be cooked, thereby efficiently cooking the food. Further, at this time, since radiant heat does not directly hit the lid 17 and the glass window 18, an abnormal temperature rise is avoided and heat radiation is also reduced.
Furthermore, since the interior can be easily observed through the glass window 18 on the top surface during cooking, there is no risk of accidentally adjusting the heat level and burning the food. Normally, the temperature inside the refrigerator is high in the central part because there is little heat radiation, but since the perforated part 30 of the reflector plate 27 and the glass window 18 radiate heat appropriately, a uniform temperature distribution is obtained. , you can cook with less uneven cooking. Furthermore, since the inner diameter of the perforated part 30 of the reflector plate 27 is smaller than the diameter of the gasket 20 that seals the glass window 18, radiant heat and the perforated part 30
The heat rays flowing upward through the gasket 20 do not directly hit the gasket 20, and as a result, the temperature rise of the gasket 20 can be reduced.

Effects of the invention As described above, according to the invention, a reflective plate is provided between the upper heater and the top surface of the lid, this reflective plate covers the heat generating part of the upper heater, and a glass window is installed in the center. Because the holes are of the same size, the radiant heat from the upper heater is reflected by the reflector, allowing for efficient cooking of food.Also, since the radiant heat is less likely to hit the lid or glass window directly, It is possible to reliably prevent abnormal temperature rises in the parts of the product, and as a result, durability and safety can be improved. Furthermore, since uniform temperature distribution is possible during cooking, and the food being cooked can be observed from the top of the lid, it is possible to check the delicate degree of heat and cook without losing heat.
