Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rice washing machine mainly used for commercial purposes.

(Prior art) Traditionally, rice in restaurants, factory cafeterias, and other stores that require a large amount of cooked rice has been washed by hand or using simple equipment for stirring the rice. was common.

(Problem that the invention aims to solve) However, in the conventional method of washing rice by hand, if the amount of rice washed at one time is too large, the weight becomes too large and it becomes impossible to wash the rice, and the washing time is also long. There was a problem that this resulted in a decrease in efficiency.
In other words, the maximum amount of rice that can be washed by hand at one time is about 5 kg, and it takes 5 to 10 minutes to wash 5 kg of rice.
The reality was that it would take several minutes. Furthermore, the method using stirring tools requires a considerable amount of human power, and there is a problem in that it is impossible for women and men to wash a large amount of rice. In view of these problems in conventional rice washing, the present invention aims to provide a rice washing machine that allows anyone to easily wash a large amount of rice.

(Means for Solving the Problems) Therefore, the present invention provides a rice washing machine including a rice washing tank with an opening at the top and a rice washing basket stored in the rice washing tank.
The rice washing tank is provided with a basket holder rotating body approximately in the center of the bottom surface thereof, which is rotatable in both forward and reverse directions on the bottom surface by a driving means and has a portion that is not equidistant from the axis of rotation, and the rice washing basket is fixed to the basket holder. It is configured to have a fitting part that is removably fitted to the rotating body, and a blade plate that protrudes into the rice-washing basket from a part of the rice-washing basket,
Solved the above problems.

(Function) The present invention is constructed as described above, and by rotating the washed rice basket by switching between forward and reverse rotation directions at intervals, the rice and water are pressed by the blades, and the inside of the washed rice basket is Rice is washed by collision and friction of rice.

(Example) An example of the present invention will be explained with reference to the drawings. Fig. 1 is a longitudinal sectional view of the rice washing machine according to the invention, and Fig. 2 is a plan view with the lid removed. 1 is a cylindrical rice washing machine body with a bottom, and 2 is a disc-shaped lid plate. The rice washing machine main body 1 is partitioned into a rice washing tank 5 at the top and a drive mechanism storage section 6 at the bottom by a partition wall 4 having a shaft hole 3 in the center. The drive mechanism housing 6 houses a drive mechanism 7 whose rotational direction is switched at predetermined time intervals by a controller with a timer. The shaft 8 is attached,
The shaft hole 3 is penetrated through the shaft hole 3. A rectangular column-shaped basket holder rotating body 9 is attached to the end of the rotating shaft 8 on the rice washing tank 5 side, and four protrusions 10 are formed radially projecting from the lower part of the basket holder rotating body 9. has been done. Note that the protruding portion 10 is a part of the basket receiver rotating body 9. Furthermore, the space between the rotating shaft 8 and the rice washing tank 5 is completely airtight. A rice washing basket 11 having a mesh size slightly smaller than the diameter of rice grains is housed in the rice washing tank 5. The rice washing basket 11 is formed in a shape along the inner surface of the rice washing tank 5 and the outer surface of the basket receiving rotating body 9. A portion along the outer surface of the basket receiver rotor 9 is a fitting portion 110 that is removably fitted to the basket receiver rotor 9, and four blade plates 12 are arranged radially on the outer surface of the fitting portion 110. It is formed in an overhanging manner. still,
13 is a water inlet, and 14 is a drain port.

In use, rice is placed in the rice-washing basket 11, water is poured into the rice-washing tank 5 through the water inlet 13, and then the drive mechanism 7 is driven. Driven by the drive mechanism 7, the rotating shaft 8 and the carton receiver rotor 9 rotate in both forward and reverse directions at predetermined time intervals, and the fitting portion 11 is attached to the carp receiver rotor 9.
The rice washing tank 11 into which the 0 is fitted rotates in the same manner, and the blade plate 12 also rotates in the same manner. As the rice-washing basket 11 rotates in both forward and reverse directions, the rice in the rice-washing basket 11 repeatedly collides and rubs against each other, and the rice is washed. In addition, the rice and water are pressed by the rotation of the vane plate 12, which increases the collision and friction between the rice and complicates the process, thereby increasing the efficiency of washing the rice. After the rice has been washed to a certain extent, the water in the rice washing tank 5 is drained from the drain port 14, and then the water inlet 1 is opened.
The rice is rinsed by pouring water into the washing tank 5 from step 3 and repeating the above-mentioned washing, or by draining water from the drain port 14 and injecting water from the water inlet 13 at the same time. Water injection from the water inlet 13 and drainage from the drain port 14 are also automatically performed by a controller with a timer (not shown). After the rice washing is completed, the washed rice basket 11 is removed from the rice washing tank 5, and the washed rice is transferred to the rice cooker.

The present invention is not limited to the above-described embodiment, and the blade plate 12 may be made to protrude into the washed rice basket 11 from the inner wall of the body or the inner wall of the bottom of the washed rice basket 11, and The shape of the portion 110 is also similar to that of the basket receiving rotor 9.
having parts that are not equidistant from the axis of rotation of
That is, any shape may be used as long as it is not cylindrical and the fitting portion 110 can be attached to and detached from the basket receiving rotating body 9.

(Effects of the invention) The present invention is constructed as described above, and includes a rice washing tank with an opening at the top and a rice washing basket stored in the rice washing tank. A basket holder rotating body is provided which is rotatable in both forward and reverse directions on the bottom surface and has a portion that is not equidistant from the rotation axis, and the rice washing basket has a fitting part that removably fits into the basket holder rotating body, and a rice washing basket. By providing a blade plate that protrudes into the rice-washing basket from a part of the basket, the rice-washing basket is rotated in both forward and reverse directions at predetermined time intervals, causing the rice in the rice-washing basket to collide and rub against each other. In addition, the rotation of the blade plate in both forward and reverse directions presses the rice and water, increasing and complicating the collision and friction between the rice and making it possible to wash the rice completely.
