Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a rice cooker.

[0002]

2. Description of the Related Art Rice cookers of this type are known, for example, those disclosed in Japanese Patent Publication Nos. 7-44897 and 7-114745. This conventional rice cooker
With a selection switch for immediate operation or reservation operation,
It was provided with a start switch operated after the operation of the selection switch and a clock display section. And
When the operator wants to start cooking rice immediately, he / she operates "immediately" of the selection switch and then presses the "start switch" to start a series of operations of weighing, washing, and cooking rice. Also, if you want to cook rice so that it will be cooked at a predetermined time, operate the "Reserve" switch, set the cooked time as the reserved time while watching the clock display, and then press the "Start switch". By pressing
Cooking was started at a predetermined time so that the rice was cooked at the set time.

[0003]

In the conventional rice cooker, when a reservation operation is performed, the rice cooking start time is not reserved, but the cooked time is reserved. Therefore, the difference between the reserved time and the current time is set. However, there was a problem that it was not possible to make a reservation if the cooking time was shorter than required. That is, if the reserved time is insufficient, the setting shortage time blinks at the same time as the buzzer sound, so the operator adds this shortage time to the currently set reservation time,
The reservation time had to be reset and the reservation operation took time.

Therefore, it is an object of the present invention to provide a rice cooker in which reservation setting is not redone.

[0005]

In order to achieve the above object, the present invention takes the following measures. That is, the feature of the present invention resides in that the rice cooking device having the reservation means capable of reserving the cooked time is provided with the clock display unit for displaying the cooked time when the rice cooking is started.

When making a reservation operation, the cooked time can be displayed on the clock display section and the cooked time can be compared with the reserved time, so that it is possible to judge whether or not there is a margin time. , Reservation setting mistake is prevented. More specifically, the rice cooker includes a selection switch for performing an immediate operation or a reservation operation, and a start switch operated after the selection switch is operated, and when the selection switch is operated immediately. The cooked time is displayed on the clock display unit, and the current time is displayed on the clock display unit when the start switch is operated.

Therefore, when making a reservation operation, first, the "immediate" selection switch is pushed to check the time when the rice has been cooked, it is judged whether there is a margin at the reserved time, and then the "reserve" button is clicked. By operating and setting the reserved time and operating the "start switch", reservation setting mistakes can be prevented.

The rice washing section 4 has a rice washing tank 8 and a water supply device 9 for supplying water to the tank 8. The water supply device 9 has a shower device that sprays water from the upper part of the rice washing tank 8. In the past, the capacity of the rice washing tank 8 was large enough to store the maximum amount of water. That is, since the amount of water to be cooked is larger than the amount of rice to be cooked, the rice washing tank 8 needs to have a large capacity, and therefore the diameter and height of the tank 8 are large and the entire apparatus is large.

However, in this embodiment, the capacity of the rice washing tank 8 is made small enough to store the amount of water required for rice washing. Then, the shortage of the adjusted water is configured such that a predetermined amount of water is supplied from the shower device after the rice is discharged. Therefore, the rice remaining in the washing rice tank 8 is washed away by the shower water supply afterward, and the washing rice tank 8 is washed.
It has the effect of leaving no rice inside.
