Description

  The present invention relates to the shape of a rice washer used in general households.

  Conventional rice washing includes those that are washed manually in the form of a bowl, and those that are stirred and washed in a special container.

In addition, related technologies include the following properties. (For example, see Patent Documents 1 and 2)
Japanese Patent Publication No. 47-032716 A plurality of stirring legs are planted in a semi-soft and parallel shape on the bottom of the outer surface of the bowl-like container body with a fine mesh, and the flexible washing rice is prevented from leaking on the upper edge of the container body A paddle is placed around the top edge of the bowl-shaped container body, and this instrument with a handle is slidably mounted in the rice-washing container. Rice washing equipment. A number of semi-flexible and tapered bar-like stirring legs are planted on the bottom of a fine mesh-like bowl-shaped container body, and the upper edge of the bowl-shaped container body is flexible with a thin wire diameter. A rice-washing apparatus characterized in that a stirring comb-like elastic body is provided in a loose upper shape with a fine mesh body.

  However, according to the above technique, the contact shape between the stirrer and the rice is small and the manual operation is performed, so that the operation until the whole rice is washed increases. Also, because of the unevenness and range of rice sharpening, the rice skin is damaged or left behind. Even when draining, the rice tends to spill, so careful action is required.

  The agitation washing type that rotates the handle connected to the agitation unit with a special container is surprisingly strong in the resistance of water and rice during agitation, so the container and lid are shaken and unstable, and it requires power to hold down. It is difficult to turn the handle. In addition, the body is difficult to wash due to its complicated shape.

  Since the water-washing type of the special container has no agitation part, the friction of washing the rice is small, and since it depends only on the water flow and water pressure, the amount of water used increases and the water bill increases. In addition, the purpose of the dedicated container is limited, and it is necessary to consider the place for the rice washer separately, which makes it difficult to store in a small kitchen.

  The rice-washing apparatus (see, for example, Patent Documents 1 and 2) has a stirrable stable body larger than the diameter of the ball and a narrow width of the bowl. Therefore, when used as a normal bowl, the inner area of the bowl is small and not easy to use. It takes a lot of wasted space by the buttocks and is difficult to store. The rice-washing method has a handle of the bowl-shaped container body and can be rotated freely, and the ball is shaken with the friction of the action during the washing of the rice, but since the stirring stable casing is wider than the diameter of the ball and there is no handle on the ball, It is difficult to work while holding and fixing with one hand. The water exchange at the time of washing the rice is a method that allows the water to flow out naturally while supplying water. However, if water is supplied and drained at the same time while mixing fresh water and muddy water, a large amount of water is required and the cost of water supply increases. Even when draining, the stirrer is larger than the ball opening, so it is difficult to hold the ball and heel part together, so children and elderly people who are unstable and have small hands and weak grip strength will lose rice. It is easy and unsuitable. In addition, the bar-shaped stirring leg has a small frictional surface, so the stirring force is weak, the number of bars is large, the shape is complicated, and the main body is difficult to wash. When water and rice enter under the armpit and rotate and agitate, the space inside and outside the ball and the armpit is wide and has a high degree of freedom. Therefore, the centripetal force is not restrained, and a gap is formed at the opening contact point and the rice tends to spill. The stirrer stable body and elastic body of the rice bran become the contact surface with the ball opening during agitation. There is a spilling difficulty. In addition, since existing balls are used and are not jointly designed with the bowl, the sizes vary, and the height from the bowl to the stirring section does not match the depth of the bowl. In this way, if the depth of the ball is too shallow with respect to the bowl, the stirring section collides with the bottom of the bowl, so that the stirring stable casing rises from the opening of the ball, and the rice flows out from there and cannot be washed well. On the other hand, if the depth of the ball is too deep, the stirring portion does not reach the rice at the bottom of the ball, and stirring and washing becomes impossible. Further, since the wet inner surface adheres to the flat inner surface of the ball, there is a difficulty that must be scraped by hand.

  The present invention is intended to solve the problems of such a conventional configuration, and an object thereof is to provide a more rational and simple rice washer.

  In order to solve the above-mentioned problems, the first invention is a joint design for increasing the efficiency of washing rice, which is composed of a ball and a bowl having a size inside the ball. A stirrer is provided on the outside of the bottom of the bowl, and a handle is provided on both sides of the edge of the bowl opening. The ball is provided with a handle on both sides of the opening edge. Water is supplied to the rice in the ball through the jar, and the grips on both sides of the jar and the ball are held together and drained through the jar. At this time, the rice washer is characterized in that the opening is close so that the rice does not spill.

  The second invention is characterized in that a single long blade (main stirring blade) is provided in the center of the bottom outside of the cage, and a short blade (auxiliary stirring blade) is provided with a gap from the center. A rice washer (described in claim 2).

  According to a third aspect of the present invention, there is provided a rice washer having a high density of irregularities in order to make it easy to remove the residue of the wet rice from the inner surface of the ball (claim 3).

  According to a fourth aspect of the present invention, there is provided a rice washer having a high density of irregularities in order to make it easy to remove the wet rice residue from the stirring portion of the koji (claim 4).

  According to a fifth aspect of the present invention, a lid having a size covering the opening of the basket and the ball is provided. An annular convex part is provided on the inner side of the lid so as to contact the inner side of the heel opening. The lid collar at the periphery has a plurality of concave and convex vertical grooves at the contact point with the collar opening, and a plurality of concave and convex vertical grooves on the upper edge of the collar opening so as to closely mesh therewith. When the handle provided at the center of the upper side of the lid is arbitrarily rotated, the lid and the outer wings of the bottom of the heel are interlocked and stirred as a gear (claim 4).

  According to the first invention, a conventional rice bowl and ball are added with a rice washing function, and can be used for three purposes. There is no need to separately consider storage for a rice washer, and space can be saved. By integrating the heel and the ball and providing a handle that also serves as the main body holding and stirring power point, the center of gravity is low and stable work can be performed with a light force. The opening of the bowl and the ball is close, the handle is easy to hold, and the characteristics of the bowl with a wide water supply / drainage surface make it possible to drain and supply water without losing rice. With a joint design that takes into account the height from the heel to the stirrer and the depth of the ball, it is finished in a form that is optimal for rice washing efficiency.

  According to the second aspect of the present invention, the cross is provided with one long blade (main stirring blade) at the center of the outer side of the heel and a short blade (auxiliary stirring blade) vertically spaced from the center. It is a form similar to a mold. The effect of this shape is that the main stirring blade stirs the whole rice and water greatly, and the auxiliary stirring blade is installed in the middle part where the influence is weakened. The rice is made smooth and the rice is efficiently stirred to improve the efficiency of rice washing. In addition, by minimizing the number of blades and leaving a gap, the corners are eliminated and the bag body is easy to wash.

  According to the third invention, the irregularities on the inner surface of the ball make it easy to drop the residue adhering to the ball by vibration without using a hand. In addition, the friction between the rice and the unevenness during stirring increases the washing efficiency.

  According to the fourth invention, the unevenness of the stirring part makes it easy to drop the residue adhering to the stirring part by vibration without using a hand. In addition, when stirring, friction is generated between the rice and the unevenness, which improves the washing effect.

  According to the fifth aspect of the invention, a lid that closely covers the opening of the bowl and the ball is provided, and the lid and the bowl are interlocked as a gear, so that the handle of the lid can be arbitrarily selected as a stirring force point in addition to the handle of the bowl and the ball it can. By providing a ring-shaped convex part on the inner side of the lid so as to be in contact with the inner side of the heel opening, when covering the lid, it is guided to a fixed position by being fitted into the heel opening, and becomes an auxiliary tool for fixing the lid and the heel. When a handle is provided in the upper center of the lid, and it is picked with a finger and rotated horizontally left and right, the center point is maintained and the rotation is smooth. It also prevents water from spilling. In addition, when preparing time for cooking or when using as a tableware, if there is a lid, it is hygienic to prevent insects and dust from entering the food.
