Description

[Detailed description of the invention] The present invention relates to a heat-retaining electric rice cooker.

This type of conventional electric rice cooker has a structure as shown in Figs. 1 and 2, where 1 is the main body of the electric rice cooker;
An inner container 2 is installed in the main body 1, an inner pot 3 is installed in the inner container 2, and a barrel heater 4 is attached to the inner container 2. Reference numeral 5 denotes a lid body that can be opened and closed, and is provided so as to cover the opening of the main body 1, and has a heat sink 13 inside. Reference numeral 9 denotes an inner lid, which is attached via a fixing bolt 7 attached to the heat sink 13 of the lid 5 and an inner lid gasket 8. Note that when the lid body 5 is closed, the inner lid 9 abuts to cover the inner pot 3. A steam cylinder 12 is attached to the inner lid 9 and has an upper end protruding above the lid 5. Note that steam holes 9a and 12a are provided at the attachment portion of the steam cylinder 12 of the inner lid 9 and at the upper part of the steam cylinder 12 so as to communicate the inner pot 3 with the outside world. 14 is a lid heater provided on the heat sink 13. In an electric rice cooker having such a configuration, steam generated during rice cooking is released through the steam hole 9a of the inner lid 9 and the steam hole 12a of the steam cylinder 12 because the inner pot 3 and the inner lid 9 are in close contact with each other.
is released to the outside world through Further, when keeping the rice warm, the cooked rice is kept warm under optimal conditions by the body heater 4 attached to the inner container 2 and the lid heater 14 attached to the heat sink 13. However, since heaters for heat retention are installed in multiple locations, there are disadvantages in that it requires many man-hours for wiring work, etc., and the number of parts increases, making it expensive. Therefore, simply use the lid heater 14.
However, the inner lid 9 is only heated from the body heater 4 via the inner pot 3, which reduces the amount of heat being heated, and increases the amount of heat radiated to the lid body 5. When the temperature became low, dew formed on the inner lid 9 while keeping it warm, and it fell onto the cooked rice, resulting in inconveniences such as deterioration of flavor, whitening of the area, and poor appearance.

This invention was made to eliminate the above-mentioned drawbacks, and when the lid is closed, the inner lid is brought into contact with the inner container, and a gasket that maintains airtightness between the inner lid and the inner lid is attached to the outer periphery of the inner lid. It is an object of the present invention to provide a device that can prevent dew condensation on the inner lid and improve performance by providing the inner lid with the inner lid, and can reduce the number of parts and reduce the cost.

An embodiment of the present invention will be described below with reference to the drawings.

The configuration of the embodiment is as shown in FIGS. 3 and 4, except for the parts numbered 2, 3, 6, 9, and 11 in the figures. Common parts are shown and their explanations are omitted. Reference numeral 2 denotes an inner container, which is built into the main body 1, and a torso heater 4 is provided in close contact with the upper outer periphery of the inner container 2. 3 has a removably housed inside the inner container 2. 6 is a back plate provided inside the lid body 5. Reference numeral 9 denotes an inner lid, which is attached via a fixing bolt 7 and an inner lid gasket 8 attached to the back plate 6 of the lid 5, and when the lid 5 is closed, the inner lid 9 is attached to the inner lid 3. Furthermore, the end of this inner lid 9 abuts on the upper part of the inner container 2. 1
1 is a gasket, which is made of an elastic material and maintains airtightness between the inner pot 3 and the inner lid 9.
is provided on the outer periphery of the inner pot 3.

The operation of this embodiment having the above configuration will be explained.

Since the inner pot 3 and the inner lid 9 are in close contact with each other through the gasket 11, the steam generated in the inner pot 3 during rice cooking is absorbed through the steam hole 9a of the inner lid 9 and the steam hole 12a of the steam cylinder 12. There is no possibility that it will be released into the outside world and overflow between the inner pot 3 and the inner container 2. Also, when keeping warm, the body heater 4 heats the inner pot 3 to keep the cooked rice in the inner pot 3 at an appropriate temperature.
Since the inner lid 9 is in direct contact with the inner container 2, it is heated more strongly than the body heater 4 without going through the inner pot 3. The temperature of the lid 5 becomes low and the inner lid 9
Although the amount of heat dissipated increases, the inner lid 9 is heated by the body heater 4 enough to compensate for this increase, and the inner lid 9 is kept at a high temperature, thereby reliably preventing dew from forming on the inner lid 9.

As described above, according to the present invention, the inner lid is brought into contact with the inner container when the lid is closed, and the seal is provided on the outer periphery of the inner container so as to eliminate the gap between the inner lid and the inner container. This has the effect of preventing dew condensation and improving performance, and also reduces the number of parts and makes it cheaper.
