Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to an electric rice cooker that cooks rice using the so-called oven cooking method.

[Technical background of the invention and its problems]

The rice cooking methods of electric rice cookers include the direct cooking method, in which a hot plate heater is attached directly to the outer bottom of the inner pot to cook the rice in the inner pot, and the other is the direct cooking method, in which a space is provided around the outside of the inner pot, and the rice is heated inside this space. There is also a kamado cooking method in which a heater is placed opposite the outer bottom of the inner pot, and the rice in the inner pot is cooked using radiant heat and convection heat generated by the heater.

The kamado cooking method cooks rice in conditions similar to the ancient rice cooking method of cooking rice by putting firewood in the oven, and is expected to produce a deliciously cooked rice.However, as a product, the electric rice cooker itself At times, the product did not have that image and was lacking in product value.

[Purpose of the invention] This invention was made with attention to these points, and its purpose is to have a simple structure,
To provide an electric rice cooker of a furnace cooking type, which can surely impress the user with the image of a furnace rice cooker and improve the product value.

[Summary of the idea]

In other words, this invention has a heat source for rice cooking inside the main body, in which the heat source for rice cooking is composed of a red-hot type heater, and a see-through part is provided on the peripheral wall of the main body opposite to the heater, and the see-through part This allows the red-hot state of the heater to be seen through from the outside of the main body, giving the impression of a stove.

[Example of idea]

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

In the drawings, reference numeral 1 denotes the main body, which contains an inner frame 3 inside an outer frame 2, and is integrally constructed in a kettle shape with an open top, with heat insulating material 4 placed around the outer periphery of the inner frame 3. An inner pot 5 is removably housed inside the inner frame 3, and there is a small gap between the outer periphery of the inner pot 5 and the inner periphery of the inner frame 3, and a relatively large gap between the outer bottom surface and the inner bottom surface. A red-hot heater 6, such as a quartz tube heater or sheath heater, formed in a circular ring shape is disposed in the space between the outer bottom surface of the inner pot 5 and the inner bottom surface of the inner frame 3.

A lid 10 is provided on the top surface of the main body 1 via a hinge 11 so as to be openable and closable. An inner lid 12 is attached to the inner surface of the lid 10.
The opening at the top of the is sealed. Further, this lid body 10 is provided with steam ports 13, 13 that allow the steam inside to escape to the outside when the pressure inside the inner pot 5 rises above a certain level during rice cooking. Note that 14 is a locking mechanism for locking the lid 10 on the main body 1, 14a is a release button for releasing the lock, and 15 is a handle attached to the top surface of the lid 10.

An operation plate 16 is provided on the front surface of the main body 1, and an operation part 17 is formed at the lower end of the operation plate 16. Inside the main body 1, a heater 6 is energized in response to the bottom temperature of the inner pot 5. Automatic switch mechanism 1 that controls
8 is provided, and one end of an operating rod 19 of this automatic switch mechanism 18 faces the operating section 17.

A transparent portion 20 is provided at a part of the peripheral wall of the main body 1 so as to face the heater 6 and enable the red-hot state of the heater 6 to be seen from outside the main body 1.
The see-through section 20 includes, for example, a see-through glass 21 mounted on the circumferential surface of the inner frame 5 facing the heater 6, an opening 22 formed in the heat insulating material 4 opposite to the see-through glass 21, and an opening 22 formed in the heat insulating material 4 to face the see-through glass 21. A rice cooking display panel 23 having a smoky color is attached to an operation panel 16 facing the rice cooker. And the above transparent glass 2
1 is formed into a concave lens shape from a heat-resistant and heat-reflective material, and the rice cooking display panel 23 is arranged adjacent to the operation section 17. Note that 24 is a heat-retaining lamp, and 25 is a heat-retaining display panel that covers this heat-retaining lamp 24.

When a predetermined amount of rice and water is placed in the inner pot 5 and the operating lever 19 is operated, the heater 6 is energized and becomes red hot, and this red heat adds radiant heat and convection heat to the inner pot 5, gradually cooking the rice. As the heater 6 becomes red hot, its visible light passes through the transparent glass 21 and the rice cooking display panel 23 to the outside of the main body 1, and therefore the red hot state of the heater 6 is displayed on the rice cooking display panel 23 just as if firewood were burning in a stove, and when the user sees this, he or she associates it with cooking rice in a stove and has a strong image of it, and at the same time, he or she recognizes that rice cooking is actually progressing.
Here, the see-through glass 21 is formed in a concave lens shape, so that the visible light from the heater 6 is diffused and the red-hot state of the heater 6 is effectively displayed over a wide area of the rice cooking display panel 23.
Since the transparent glass 21 has heat reflectivity, the heat of the heater 6 is not dissipated wastefully to the outside of the inner frame 3 through the transparent glass 21, and therefore, it is possible to prevent a decrease in heat efficiency and ensure safety.
Since 3 has a smoky color, it can moderately suppress the transmission of visible light and reduce irritation to the user's eyes, and has the advantage of blocking the line of sight to the messy structural parts inside the main body 1 when the electric rice cooker is not in use, preventing a deterioration in the appearance.

As the rice cooking progresses in this way and the rice in the inner pot 5 is cooked, the automatic switch mechanism 18 is activated and the operating rod 19 is returned to its original state, and the power to the heater 6 is cut off. The red-hot state display on the display panel 23 disappears, and it is thus possible to know that the rice cooking is complete. Traditionally, general electric rice cookers are also equipped with a pilot lamp that dims and dims depending on whether the current is turned on or off to the heater. In such a case, even if the heater is actually energized, the pilot lamp may not turn on, which poses a problem in terms of reliability. However, in this embodiment, since the red-hot state corresponding to the energization of the heater 6 is directly displayed on the rice cooking display panel 23,
There is no room for the above-mentioned problems to occur, and reliability can be maintained reliably.

FIG. 3 shows another embodiment of this invention, in which the see-through glass 21 is made of a heat-resistant and heat-reflective material in the shape of a convex lens, and a part of the heater 6 is disposed at its focal point. In such a configuration, since the red-hot part of the heater 6 is enlarged and displayed on the rice cooking display panel 23,
The image of cooking in a stove is further enhanced.

[Effect of idea]

As explained above, according to this invention, the red-hot state of the heater can be seen through from the outside of the main body, so based on that transparency, it gives a strong impression to the user that it is a stove-top cooking device, and the product value increases. This has the effect that it is possible to reliably achieve an improvement in .
