Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a rice cooker that is used on a daily basis in general households.

Conventional configurations and their problems In most of the configurations of rice cookers and electronic jars that have become rapidly popular in general households in recent years, the pot is removably housed within the main body.

An inner frame having an inner dimension larger than the outer dimension of the pot was provided inside the bottomed cylindrical body, and the pot was removably housed within this inner frame. In this case, the gap between the inner surface of the inner frame and the outer surface of the pot is only a few millimeters, which is enough to allow the pot to be smoothly attached and detached in order to position the pot in the specified position. ,
It is difficult for air to flow into the space formed by the pot and the inner frame, and as a result, the space becomes negative pressure, making it difficult to remove the pot, resulting in operational inconvenience.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a rice cooker in which the pot can be easily inserted into a predetermined position and the pot can be removed smoothly.

Structure of the Invention In order to achieve the above object, the rice cooker of the present invention has the following features:
When the pot is removed, the inner frame is provided with an air intake valve that prevents the inner frame space from becoming negative pressure, that is, the inner frame is provided with an air intake valve that opens in the direction of sucking air into the inner frame, and It is equipped with an air inlet that communicates with the suction valve, and due to the action of the air suction valve, when the pot is inserted, the pressure in the space between the pot and the inner frame increases, so there is no impact on the pot. The pot can be inserted smoothly without any pressure being applied, and when the pot is removed from the main body, the air intake valve is opened and outside air flows into the pot and the interior through the air inlet and the air intake valve. Since it enters the space within the frame, this space does not become under negative pressure, and as a result, the pot can be smoothly removed from the main body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 1 to 3, reference numeral 1 denotes a bottomed cylindrical instrument body, and the bottom of the instrument body 1 has an air inlet 2.
Although not shown, electrical components and the like are arranged at the bottom. 3 is a bottomed cylindrical inner frame provided inside the instrument body 1, and 4 is an upper frame connecting the upper part of the instrument body 1 and the upper part of the inner frame 3. Note that a heat insulating material 5 is inserted between the inner frames 3 of the appliance main body 1 over the entire circumference. Furthermore, legs 6 are provided at the bottom of the instrument body 1. Reference numeral 7 denotes a cylindrical pot with a bottom, and the pot 7 is dimensioned to create a gap between the inner surface of the inner frame 3 and the outer surface of the pot 7 to the extent that the pot 7 can be smoothly attached to and removed from the inner frame 3. 8 is a heating element installed at the inner bottom of the inner frame 3; 9 is a thermostat that detects the temperature at the bottom of the pot 7; 10 is an air intake valve installed at the bottom of the inner frame 3; It opens in the direction of sucking air into the inner frame 3,
Normally closed. 11 is a lid body; this lid body 11
is attached to the upper frame 4 via a hinge portion 12 so as to be openable and closable. Reference numeral 13 denotes a lid lever provided on the lid body 11.

Next, the operation of the rice cooker configured as described above will be explained.

As shown in FIG. 2, first, the lid 11 is opened by disengaging the foot lever 13, and when the pot 7 is lifted upward in order to take out the pot 7 from inside the inner frame 3, the outer surface of the pot 7 and the inner The space surrounded by the inner surface of the frame 3 becomes negative pressure, and this negative pressure
When the negative pressure becomes higher than its own weight, the air intake valve 10 opens. As a result, air passes through the instrument body 1 from the air inlet 2 provided on the bottom of the instrument body 1, and then flows into the inner frame 3 through the air intake valve 10, bringing the pressure inside the inner frame 3 to atmospheric pressure. Bring it closer. As a result, the pressure inside the inner frame 3 does not become a negative pressure greater than the weight of the air suction valve 10, so the pot 7 can be taken out smoothly. On the other hand, when inserting the pot 7 into the inner frame 3, the pressure in the space surrounded by the outer surface of the pot 7 and the inner surface of the inner frame 3 increases, so the air suction valve 1
0 is closed, and as a result, air in the space gradually flows out from the gap between the pot 7 and the upper frame 4 provided on the upper part of the inner frame 3, and as a result, the outer surface of the pot 7 and the inner frame 3 The pressure in the space surrounded by the inner surface of Thereby, the pot 7 is not inserted all at once, but is inserted gradually, so that a strong impact is not applied to the pot 7 or the heating element 8, and the pot 7 can be smoothly inserted into the inner frame 3.

Furthermore, since the air intake valve 10 is normally closed, water, dust, etc. do not enter the inside of the appliance body 1, and as a result, the rice cooker can be used hygienically without malfunctions.

Effects of the Invention As described above, according to the present invention, when a pot is inserted into the inner frame provided in the appliance body, impact is less likely to be applied to the pot, and as a result, the pot is less likely to be damaged. When taken out from the inner frame, it can be taken out smoothly and is easy to use. Furthermore, by providing an air intake valve, even if water or the like is accidentally spilled into the inner frame, it will be difficult to enter the appliance body, and as a result, water will not leak into the electrical parts installed between the inner frame and the appliance body. This eliminates the need for
It is possible to provide a rice cooker that is also highly safe.
