Description

  The present invention relates to a rice cooker including a lid opening / closing device that suppresses the height when the lid is opened.

  Rice cookers are often stored inside kitchen furniture such as storage racks, range tables, kitchen counters, etc. in the kitchen, but the rice cooker lid is stored in the kitchen furniture. When the body is opened, the lid body rotates upward and collides with the inner top surface of the kitchen furniture, and may not be completely opened. Therefore, the kitchen furniture may be a slide shelf that can pull out the mounting table of the rice cooker storage unit forward. There is also a kitchen furniture where the top of the rice cooker storage is raised so that it does not collide with the top even if the lid of the rice cooker is opened. Furthermore, the rice cooker may be placed on the upper surface of the kitchen furniture.

  However, when a slide shelf that can be pulled forward is used, it is necessary to pull the slide shelf forward each time the lid of the rice cooker is opened, which is complicated. In addition, it is common for the lid of rice cookers to rotate backward and open, and the lid may collide with the top surface of the kitchen furniture unless the slide shelf is fully pulled out. In order to pull out the shelf completely, a space for pulling out the slide shelf is required in front of the slide shelf. On the other hand, when a kitchen furniture with a raised top surface of the rice cooker storage or a rice cooker placed on the upper surface of the kitchen furniture, the space above the rice cooker cannot be used effectively. There is a problem that it ends up.
