  The present invention is a rice cooker that performs cooking by heating an inner pot that contains an object to be heated (such as rice or water), and particularly has a function of cooling and condensing steam generated from the object to be heated during cooking. Related to rice cookers.

  Conventionally, a rice cooker designed to condense steam generated during cooking from an object to be heated contained in an inner pot by introducing it into a container (tank) containing cooling water and dissipating it in the cooling water. It is known (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-192134 (FIG. 1)

  In such a thing, the amount of water with which the cooling water (tap water) was decided before rice cooking is accommodated, and a tank is set to a rice cooker. However, when the cooling water is poured into the tank, it is very difficult to adjust the amount of water to the scale of the tank because the water is poured directly from the faucet to the scale marked on the tank (engraved, printed, etc.). It was. Also, the allowable range of the scale is very narrow, which makes it difficult to set.

  The technical problem of the present invention is to make it possible to easily adjust the amount of cooling water so that the amount of cooling water becomes a prescribed amount when the cooling water is stored in the tank.

  A rice cooker according to the present invention has a main body having a heating means in which an inner hook is detachably accommodated, a lid that is hinged to the main body and closes an upper opening of the inner hook so as to be openable and closable, and stores cooling water. The tank is detachably installed in the main body, and the steam generated from the heated object in the inner pot during cooking is interposed between the inner pot and the tank, and is then dissipated in the cooling water by dissipating it into the cooling water. A steam conduit to be constructed, the tank is made of a translucent member, and the amount of water is at a position that becomes the water level when the water surface is applied to the drainage part by tilting it obliquely with the specified amount of cooling water in it. A scale for adjustment is provided.

  According to the rice cooker of the present invention, the water level scale is tilted obliquely in a state where the specified amount of cooling water is contained, and is provided at a position that becomes the water level when the water surface is applied to the drainage part. The water level can be adjusted to the scale while adding a lot of water, tilting the tank and discarding the cooling water, so the water volume can be adjusted very easily and the usability is improved.
