Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is capable of converting so-called bulk ice produced in an electric refrigerator or the like into ice shaving and crushing with one machine to produce snow-like ice or split ice. This invention relates to a combined ice cutting/ice crushing machine that can obtain ice at will.

(Conventional technology and its problems) Conventionally, when snow-like ice or ice cubes were required, emphasis was placed on the quality and processing capacity of each, and it was customary to install a dedicated ice shaver or ice crusher. However, recently, due to convenience, restaurants and the like have started to demand machines that have both of these functions. This kind of device is disclosed in Japanese Patent Publication No. 59-50036 and Japanese Utility Model Application No. 143282-1982.

Among these, the one published in Special Publication No. 59-50036 is
The ice-breaking cutter is fixed at a position slightly lower than the case surface facing the outlet of the storage case, and the outlet in front of it has a structure that opens and closes a variable lever that makes the opening area smaller when cutting ice and larger when breaking ice. However, since the ice-breaking blade is fixed at the above-mentioned position, there is a tendency for the loose ice to jump during ice-breaking, resulting in a situation where it slides upward. In addition, in Utility Model Publication No. 59-143282, the ice storage chamber (case) side wall has two ice-shaving blades facing the outlet and a crushing blade in front of the ice-shaving blade protruding inward of the case. In addition, when the crushing blade acts on loose ice, the area of the rear discharge port is made larger, and when the ice is shaved, the area of the discharge port is made smaller, so the link mechanism is designed so that the discharge port cover goes in and out in the opposite direction to the crushing blade. Since it has become linked,
The loose ice rotating inside the case passes through these two openings, causing a lot of friction, and the link mechanism is also relatively complex.

(Means for Solving the Problems) The present invention aims to eliminate the disadvantages of the conventional device described above, and includes a rotary blade that rotates within a cutting case, and an ice cutting blade attached to the case. is equipped with a discharge port facing its rear edge, the area of the discharge port is expanded to face the ice feeding direction, and the discharge port is rotatably supported by a shaft outside the central portion in the length direction of the discharge port. In addition, when cutting ice, a cutter block equipped with a plurality of ice-breaking blades at appropriate intervals is rotated so that the ice-breaking blades are tilted forward to close the front part of the outlet so that it is flush with the inner surface of the case. Only the front part of the ice-shaving blade is opened, and when ice is broken, the ice-shaving blade is rotated so as to stand up and protrude into the case, thereby opening the front part of the blocked outlet. By rotating the cutter block by operating the handle, the outlet can be used for either purpose, making it possible to shave ice and crush ice with one machine.

(Example) Embodiments of the invention will now be described with reference to the accompanying drawings.
