Description

[Detailed explanation of the invention] This invention covers everything from storing rice to measuring rice and water, washing rice,
The present invention relates to a power connection configuration in the rice cooker section of a rice cooker that automates the rice cooking process from preparation, cooking, and keeping warm.

In conventional rice cookers, the rice cooker pot is removed from the main body of the rice cooker after rice cooking is completed, and the rice cooker section is fixed within the main body.

Therefore, when only the rice cooker is taken out after the rice has been cooked, there is a risk of burns due to the rice cooker being too hot, and once the rice cooker is taken out, it cannot be kept warm, making it difficult to use.

The present invention eliminates the above-mentioned conventional drawbacks and provides an easy-to-use automatic rice cooking device.

An embodiment of the present invention will be described in detail below. In the drawing, 1 is a rice cooking device main body, 2 is a rice pot, 3 is a rice measuring device, 4 is a rice washing device, 5 is a rice cooking pot, 6 is a drawer panel, and 7 is a drawer main body, which is fixed to the drawer panel 6. 8 is a guide fixed to the drawer main body 7, 9 is a guide fixed to the rice cooker main body 1, 10 is a roller fixed to the guide 8, 11 is a roller fixed to the rice cooker main body 1, and the guide 8, 9 and rollers 10 to pull out the drawer panel 6 toward the front, the drawer main body 7 is pulled out smoothly. 12 is rice cooker 5
The main body of the convex part of the magnetic plug attached to the lower side of the rice cooker, 13, is the main body of the concave part of the magnetic plug that is connected to the convex part of the magnetic plug body 12 and slides into the through hole of the partition plate 14 fixed to the main body 1 of the rice cooker. It is attached freely. 15 is a terminal attached to the magnetic plug convex body 12, 16 is a terminal 15
Terminal board 17 is fixed with screws to terminal board 1.
It is connected to the heating element of the rice cooker 5 by a lead wire connected to the rice cooker 5. Reference numeral 18 is a steel plate attached to the front surface of the magnet convex body 12, and 19 is a permanent magnet that attracts and detaches from the steel plate 18.
The frame body 24 is slidably inserted into the frame body 3. 20 is a terminal that is attached to the magnetic plug recess body 13 and comes into contact with the terminal 15;
5 to a lead wire 22 connected to a power source. A spring 21 is inserted between the frame 24 and the terminal 20, and its elasticity acts in the direction of pressing the terminal 20 against the terminal 15. Reference numeral 23 denotes a spring inserted between the magnetic plug recess body 13 and the partition plate 14.
The elastic force acts in the direction of pressing the magnetic plug convex body 12.

The rice cooker 5 is removably installed on the drawer body 7, and the rice cooker 5 can be taken out from the drawer body 7 by pulling out the drawer body 7.

Next, its operation will be explained.

When cooking rice, the rice cooker 5 is placed on the drawer main body 7 with it pulled out, and then the drawer main body 7 is pushed into the rice cooker main body 1. In this state, the magnetic plug convex body 12 and the magnetic plug concave body 1 attached to the rice cooker 5 are connected to each other.
At the same time, the terminals 15 and 20 are brought into good contact with each other due to the elasticity of the spring 21 and the magnetic force between them. In addition, since the permanent magnet 19 attracts the steel plate 18 fixed to the magnetic plug convex body 12, the elasticity of the spring 21 acts well on the contact between the terminal 15 and the terminal 20, and the connection between the power source and the heating element is established. Lead wire 22, terminal plate 25, terminal 20, 1
5. This is done via the terminal plate 16 and lead wires 17.

When rice cooking is finished, when the drawer main body 7 is pulled out, the terminals 15 and 20 are connected by the magnetic force between the steel plate 18 and the permanent magnet 19, and the spring 21,
Since the contact is maintained only by the elastic force of 23 and there is no other mechanical connection, it can be easily separated, and the current to the heating element is cut off.

As described above, the present invention has a magnetic plug recess main body that has a terminal connected to a power source and a permanent magnet attached to a frame that is slidably mounted inside the rice cooker main body. The rice cooker, which is removably placed in a drawer body that can be freely inserted and taken out, has a terminal that is connected to a heating element and comes into contact with a terminal connected to the power source, and also has a steel plate that is attracted and removed by the permanent magnet. A magnetic plug convex body is provided.

Therefore, the power supply circuit of the rice cooker is automatically opened and closed by inserting and removing the drawer body into the rice cooker body, eliminating the need to manually connect and disconnect the power plug every time rice is cooked. You can avoid forgetting to insert it. In addition, the power to the rice cooker is automatically turned off simply by pulling out the drawer body from the rice cooker body, which improves operability such as attaching/detaching and moving the rice cooker.

As described above, the present invention has great practical value as it provides an easy-to-use rice cooking device with a simple configuration.
