Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in the location of a buzzer in a rice cooker.

[Prior Art] Rice cookers that heat and cook rice using electricity are now popular throughout the country and have become essential appliances in the kitchens of every household. That's why the enthusiasm of each manufacturer in developing this technology is amazing.
As the name suggests, it is constantly evolving, with new products being released one after another, and the number of novel parts increasing each time. Buzzers are one of the new parts, and rice cookers equipped with buzzers are configured to sound when rice cooking is complete to notify the user.

[Problems to be Solved by the Invention] By the way, there are usually two boards on which electronic components related to power supply and control are mounted in a rice cooker: an operation board placed on the lid of the rice cooker, and a power supply board installed at the bottom. However, the buzzer is located on the power supply board at the bottom of the rice cooker. Second
The figure is a configuration diagram showing this state, where 1 is a buzzer, 2 is a power supply board, 3 is an operation board, 4 is a microcomputer, and 5 is a cable.

Buzzer 1 is placed on the power supply board compared to conventional buzzer 1.
This is because the device is large and quite heavy, so it would be unreasonable to place it on the operation board that is placed on the lid, which is constantly opened and closed. However, the microcomputer 4 that detects the completion of rice cooking and issues an instruction to the buzzer 1 to sound the buzzer is located on the operation board 3 placed on the lid. The cable 5 must be wired to the power supply board 2 at the bottom. Cable 5 is not a big deal in terms of length, but in order to withstand the bending caused by opening and closing the lid, it is necessary to use a fairly expensive cable with good flexibility, and in terms of cost, it is less than that of a conventional rice cooker. This was one of the problems.

The present invention was made to solve the above problems, and
The aim is to provide a location for placing the buzzer that reduces costs.

[Means for Solving the Problems] In order to achieve the above object, in the rice cooker according to the present invention, the buzzer is disposed near a microcomputer or the like that issues an instruction to sound the buzzer.

[Function] Since the buzzer is placed near the microcontroller as described above,
The cable 5 connecting the buzzer 1 and the microcomputer 4 is almost unnecessary.

[Embodiment of the Invention] FIG. 1 is a configuration diagram showing the locations of a buzzer 1 of a rice cooker showing an embodiment of the present invention, and 6 is a cable. As shown in the figure, the buzzer 1 is disposed on an operation board 3 disposed on the lid. One reason this has become possible is that a small and lightweight buzzer has recently been developed and commercialized.

Therefore, the cable 6 connecting the buzzer 1 and the microcomputer 4 can be very short, and there is no need to take flexibility into account, so it does not need to be an expensive cable, resulting in a significant cost reduction.

[Effects of the Invention] The present invention changes the location of the buzzer of the rice cooker from the power supply board at the bottom of the rice cooker to the operation board placed on the lid, so the length of the cable connecting the buzzer and the microcomputer is significantly reduced. Both ε can be shortened to , and an inexpensive cable can be used.
This greatly contributed to reducing the cost of rice cookers.

[Brief explanation of drawings]

FIG. 1 is a block diagram showing the placement of a buzzer according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the placement locations of the buzzer in a conventional rice cooker. In the figure, 1 is a buzzer, 2 is a power supply board, 3 is an operation board, 4 is a microcomputer, and 5.6 is a cable. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] A power circuit board provided at the bottom of the rice cooker body, a buzzer that notifies rice cooking completion, etc., and an operation board provided at a location away from the bottom of the rice cooker on which a component that issues an instruction for the buzzer to sound is mounted. A rice cooker, characterized in that the buzzer is provided on the operation board.
