Description

[Detailed explanation of the invention] This invention places the rice cooking thermostat on the side.
The purpose is to make it possible to cook delicious rice.

In the conventional rice cooker, a rice cooking thermostat 28' is retractably disposed on a protrusion B formed approximately at the center of the outer pot 3', and its upper surface abuts on the inner pot 8'.

However, since the sheathed heater 6' is disposed along the circumference of the bottom of the inner pot 8' to heat the inner pot 8', the radiant heat of the sheathed heater 6' is blocked by the thermostat 28'. The heating temperature of the rice on top became low, causing uneven cooking of the rice as a whole, and as shown in Figure 2, the low-temperature area A became depressed and the taste deteriorated.

The present invention has been developed in view of the above-mentioned drawbacks, and the embodiments of the present invention will be described below with reference to the drawings. 1 is a cylindrical outer frame with a back cover 2 disposed at the bottom, and 3 is the outer frame. 1
This is an outer pot housed inside via an annular frame 4, and has a heat-generating rice cooking heater 6 such as a sheathed heater on the bottom four parts 5 and a heat-retaining heater 7 on the outer surface.

Reference numeral 8 denotes an inner pot which is detachably placed in the outer pot 3, and is spaced apart from the inner wall of the outer pot 3 by a predetermined distance to form a side space 9, and whose outer bottom surface is 30 steps apart from the outer pot 3. It is in contact with part 10.

Reference numeral 11 denotes a partition plate disposed at a predetermined distance between the outer pot 3 and the inner pot 8, and a heat insulating material 12 is loaded between the partition plate 11 and the inner pot 3.

Reference numeral 13 denotes an inner lid that is placed on the upper periphery of the inner pot 8 and removably covers the upper surface of the inner pot 8, and has a plurality of steam holes 14...
is bored and the projection piece 15 is fixed.

Reference numeral 16 denotes an outer lid in which a heat insulating material 17 such as glass wool is loaded; 18, a pivot 19 fixed to the upper surface of the outer lid 16 and rotatably connected to the outer wall of the outer frame 1 at one end; and a connecting piece at the other end. A handle 20 has a handle, and 21 is an auxiliary lid attached to the back surface of the outer lid 16 so as to be able to move up and down within a predetermined range.
is abutted against the upper flange portion 23 of the outer pot 3 and forms an upper space 24 between it and the inner lid 13.

An elastic annular locking piece 2 is provided approximately in the center of the auxiliary lid 21.
5, and is detachably attached to a mounting member 26 provided on the outer lid 16.

27 is a heat-retaining thermostat that controls the temperature of the heat-retaining heater 7; 28 is a rice-cooking thermostat attached to the outer surface of the outer pot 3 like the heat-retaining thermostat 27; Heater 6
This is to turn off.

The side space 9 and the upper space 24 are brought into communication.

According to such a configuration, the hot air from the rice cooking heater 6 is transferred to the inner pot 8.
The bottom part of the rice cooker can be heated uniformly, eliminating uneven cooking unlike the conventional method.Moreover, the hot air from the heating element 6 for rice cooking reaches the upper space 24 through the side space 9, a part of which is shown in the figure. Although the steam comes out from the steam vent tube, it is as if the entire inner pot 8 is covered with hot air.Compared to conventional methods where heating is done only from the bottom, the entire inner pot is heated, and the rice is delicious. is obtained.

As described above, the present invention includes an outer pot with a rice cooking heater exposed on the bottom and a rice cooking thermostat provided on the outer surface, and a detachable structure that forms a side space in and around the outer pot. an inner pot that can be placed freely; an inner lid that is placed to cover the top surface of the inner pot; an outer lid that covers the top surface of the inner pot that can be opened and closed; and between the outer lid and the inner lid. and an auxiliary lid whose peripheral edge abuts against the upper flange portion of the outer pot when the outer lid is closed, and which forms an upper space communicating with the side space between the outer lid and the inner lid. This eliminates the conventional situation where rice that is directly above the rice cooking thermostat cannot be cooked properly, and the rice is heated evenly from the entire bottom of the inner pot, while being heated so that the area around the inner pot is surrounded by hot air. You can get delicious rice.
