Description

  When cooking or eating at a table, the present invention pulverizes a granular material to be crushed such as spices or seasonings such as pepper, yam, sesame or rock salt to a desired particle size (size). The present invention relates to a grinder that is used for sprinkling fresh ingredients on food or cooking without losing the flavor of the pulverized product.

  The grinder is, for example, a storage part for granular objects to be crushed, a housing part composed of a relatively rotatable outer cylinder and an inner cylinder, and accommodated in the housing part, and one of the outer cylinder and the inner cylinder, respectively. A cylindrical outer blade whose blade shape is formed on the inner peripheral surface that rotates integrally with the outer peripheral blade, and is disposed in a state surrounded by the space surrounded by the inner peripheral surface of the outer blade. And a pulverizing section for pulverizing the object to be crushed, which is composed of an inner blade having a blade shape.

  In addition, the grinder is usually used in a storage posture in which the storage portion is erected below the crushing portion, and the storage portion is turned upside down from the storage posture so that the storage portion is above the crushing portion. Either posture or posture is assumed. And in the use posture, the outer cylinder and the inner cylinder are rotated relative to each other, and the crushed material obtained by crushing the material to be crushed with the outer blade and the inner blade is sprinkled on food or cooking. After that, it is returned to the storage posture and stored again.

  Since the flavor of the material to be pulverized is lost with the passage of time after pulverization, it is desirable to use it immediately after pulverization. However, when the grinder is used in the use posture and then returned to the storage posture, the pulverized material remaining between the outer blade and the inner blade and the residue to be pulverized in the middle of pulverization Is moved to the storage portion by its own weight and stored in this state. Accordingly, at the next use, the residue from the previous use moves from the storage unit to the pulverization unit, so that the residue is pulverized again and sprinkled on foods, dishes, etc. It is a big obstacle. In addition, when the storage portion is made of a transparent material, a state in which the pulverized material and the remaining material are mixed in the storage portion is visually recognized, which causes a problem that the appearance is deteriorated.

Therefore, as a means for eliminating these inconveniences, for example, a shutter mechanism including three partition plates is provided, and the upper partition plate and the lower partition plate of these partition plates are connected to one of the outer cylinder and the inner cylinder. To the other, an intermediate partition plate is connected to the other, and a through hole for the object to be crushed is provided in the partition plate so that the through hole of the upper partition plate and the through hole of the lower partition plate do not overlap vertically. Has been proposed (see, for example, Patent Document 1). In this puller, when the outer cylinder and the inner cylinder are relatively rotated in the use posture, the through hole of the upper partition plate communicates with the through hole of the intermediate partition plate, and the through hole of the upper partition plate The object to be crushed enters the intermediate partition plate side. Subsequently, when the outer cylinder and the inner cylinder are relatively rotated, the through hole of the intermediate partition plate communicates with the through hole of the lower partition plate, and the object to be crushed passed to the intermediate partition plate side is It moves to the crushing part through the through hole of the lower partition plate. And even if the grinder is returned to the storage posture after pulverization of the object to be crushed, all of the through holes of the upper partition plate, the through holes of the intermediate partition plate, and the through holes of the lower partition plate are in communication at the same time. Therefore, movement of the residue to the storage unit is prevented.
