DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inspection window mechanism of a rice washing apparatus for automatically washing rice.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No.
There is an automatic rice cooker disclosed in Japanese Patent Publication No. 181113/1992, in which a rice storage unit for storing rice, a measuring unit for measuring and discharging the rice in the rice storage unit, and a rice discharged from the measuring unit via a stirring mechanism. The rice washer is provided with a rice washing section for washing the rice, and a rice cooking section for cooking the rice discharged from the rice washing section. A disk-shaped agitator is provided near the bottom of the rice washing section.

[0003]

In the above-mentioned prior art, there is a problem that the rice washing tank in the rice washing section has no window, and it is difficult to check and clean the internal stirring mechanism. This problem can be solved to some extent by forming an inspection window in the rice washing tank and providing a window cover for opening and closing the window. However, such a window cover requires a sealing material to prevent water leakage. If the sealing material is formed in a minimum shape required for watertightness, that is, in a square frame shape, the sealing material itself is not provided. Another problem is that a step is formed in the step, and rice remains on the step, albeit slightly.

According to the present invention, rice is washed so that no rice remains on the sealing plate by forming a sealing material of a window cover for opening and closing an inspection window formed in the rice washing tank with an elastic sealing plate having substantially the same inner surface. It is an object to provide an inspection window mechanism of the device.

[0005]

A specific means for solving the problem in the present invention is a rice washing apparatus in which weighed rice and water are stored in a rice washing tank 16 and the rice is washed while being stirred by the stirring mechanism 1. An inspection window 70 is formed in the rice washing tank 16 and a window cover 71 for opening and closing the window 70 is provided.
The window cover 71 is formed by attaching an elastic seal plate 75 having an inner surface substantially flush with the inner peripheral surface of the rice washing tank 16 to the inner surface of a plate 72 pivotally supported by the rice washing tank 16. Is formed of a plate having an area larger than that of the window 70.

[0006]

The rice washing section 5 rotates the vertical axis 2 after putting the measured rice and water in the rice washing tank 16, and the rod-shaped stirring body 17 rotates therein to wash the rice while stirring. When the window cover 71 is opened, inspection and cleaning of the rod-shaped stirring body 17 and the like become possible. When the window cover 71 is closed, the seal plate 75 is in close contact with the outer surface of the rice washing tank 16 to prevent water leakage. The inner surface of the seal plate 75 is substantially flush with the inner peripheral surface of the rice washing tank 16 so that there is no step.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 to 9 show an automatic rice cooker provided with a rice washing device. The automatic rice cooker is roughly divided into a main body frame 82 having casters 81, a rice storage unit 3 for storing rice, and a rice storage unit 3 in the rice storage unit 3. Measuring unit 4 for measuring and discharging the rice, and a rice washing unit 5 for washing the rice discharged from the measuring unit 4 via the stirring mechanism 1.
And a rice discharging unit 6 for discharging rice from the rice washing unit 5, a rice cooking unit 7 for cooking rice discharged from the rice discharging unit 6, and a control unit 8 disposed on the front surface of the main body frame 82. Have been.

The rice storage unit 3 has a funnel type rice storage 9,
The rice storage 9 has an opening at the top and a funnel at the bottom, and a rice storage sensor 10 for detecting the amount of rice in the storage is provided on the inclined wall. Inside the rice storage 9, a comb member 11 for preventing foreign matter from entering is provided detachably. The weighing unit 4 is a rice storage 9
, A cutting motor 13 for discharging a predetermined amount of rice in one rotation, a weighing motor 14 for rotating the cutting device 13, and a weighing count sensor 15 for detecting the amount of rotation of the cutting device 13. And

The rice washing section 5 has a rice washing tank 16 which is arranged below the measuring section 4 and stores the rice discharged from the cutting means 13. A window 70 for internal inspection and cleaning is formed at the front of the rice washing tank 16, and the window 70 is closed by a window cover 71 so as to be freely opened and closed. The window cover 71
As shown in FIGS. 1 to 3, an elastic seal plate 75 made of rubber or sponge is surface-bonded to the inner surface side of an arc-shaped plate member 72, and this seal plate 75 is a single plate having an area larger than the window 70. It is formed and the inner surface is flush, and the periphery of the inner surface comes into contact with the outer peripheral surface of the rice washing tank 16 without a step where rice is accumulated.

That is, when the window cover 71 is closed, the sealing plate 7
A step corresponding to the thickness of the rice washing tank 16 is formed between the inner surface of the rice washing tank 5 and the inner peripheral surface of the rice washing tank 16, but since the step is extremely small, rice does not accumulate. A support plate 83 is screwed to a bracket 73 fixed to the rice washing tank 16. One end of the plate member 72 is pivotally supported on the support plate 83 via a pivot shaft 74, and a screw 84 is provided on the outer surface of the other end of the plate member 72. An engaging piece 85 is attached via the rice washing tank 16 so that the circumferential position can be adjusted. A so-called shrimp metal fixture 76 is provided on the outer peripheral surface of the rice washing tank 16. When the hook 86 of the fixture 76 is engaged with the engagement piece 85 and the lever 87 is rotated, the plate material 72 is removed from the rice washing tank. It can be closed while pressed against the 16 side.

When the lever 87 is rotated, the bracket 73 is elastically deformed to generate a force for pressing the plate 72 against the rice washing tank 16. This pressing force may be generated by interposing a spring material between the bracket 73 and the support plate 83. When the elastic sealing plate 75 is pressed against the outer peripheral surface of the rice washing tank 16, the central portion thereof
Is slightly projected into the window 70 so as to fill the step of the thickness of the rice, the inner surface thereof is substantially flush with the inner peripheral surface of the rice washing tank 16, the thickness step is almost eliminated, and the rice accumulation is surely prevented. Will be blocked.
