[Detailed description of the invention] [Industrial application field] The present invention is an ice shaving and ice crushing machine that can obtain snow-like ice and crushed ice from so-called cube ice, that is, ice cubes produced using an electric refrigerator or an ice maker. Regarding.

[Conventional technology] Conventionally, when producing snow-like ice or crushed ice from ice cubes,
Because emphasis was placed on the quality and processing capacity of each, it was customary to install dedicated ice shavers and ice crushers, but recently restaurants and other establishments have begun to install machines that serve both purposes for convenience. has become in demand.

As a proposal of this type, there is an invention described in Japanese Patent Application Laid-open No. 153359/1983, but the outline of this invention is as shown in FIG.
, a rotary blade 10 inclined upwardly along the inner surface which serves as a sliding surface for ice cubes, a discharge port 18 provided in the cutting case 12 , and an ice cutter attached to the outer periphery of the case facing the ice discharge port 18 . It consists of a blade 22 and an ice-breaking blade 30. Detailed cross-sectional views of the installation of the ice-shaving blade 22 and the ice-breaking blade 30 are shown in FIGS. 6 and 7. Move further back. The ice-breaking blade 30 is inserted into and taken out of the cutting case 12 using the cutter block 26 to which the ice-breaking blade 30 is attached.
This is done by the rotation of the This knife block 2
6 is rotated around a rotating shaft 29, and the ice-breaking blade 30 is stopped at the extended position or the retracted position by the action of the toggle spring 27. The cutter block 26 closes the front portion of the ice outlet 18 in the entry position, ie, during the ice cutting operation, to form an ice cube sliding surface.

On the other hand, when crushing ice, the cutter block 26 is rotated clockwise to cause the ice crushing blade 30 to protrude into the cutting case 12, and the crushed ice pieces are discharged from the opening in the front portion of the ice discharge port 18. Therefore, according to the above invention, the size of crushed ice is determined to be only one type.

However, in recent years, due to the diversification of consumer needs, various sizes of crushed ice have been required, and the above-mentioned proposals are no longer able to meet these demands.

[Problems to be solved by the invention] The present invention has been made in view of the above-mentioned problems in ice-shaving and crushing machines that can produce snow-like ice or crushed ice with a single machine. The purpose of the present invention is to provide a combined ice-shaving and crushing machine equipped with a multi-stage switching device for crushed ice size, which can obtain crushed ice of various sizes.

[Means for Solving the Problems] The ice cutting/ice crushing machine according to this invention is equipped with a rotary blade that rotates within a cutting case, an ice outlet in the case, and an ice cutting blade at the rear of the outlet. The ice-breaking blades are attached to the back surface of the cutting case so that the ice-breaking blades are supported by a blade block rotatably supported on a mounting member in the front part thereof, and the rotation of the blade block is An angle switching device equipped with a locking piece that is directly connected to the shaft, rotates concentrically, and slides in the radial direction, and the mounting member is provided with a plurality of locking grooves in which the locking pieces engage. It is.

[Operation] The ice cubes placed in the cutting case slide while being pressed against the inner surface of the cutting case by centrifugal force due to the rotation of the rotor blades. When cutting ice, an ice cutting blade facing the discharge port of the cutting case is made to protrude from the inner surface of the case, and the sliding ice cubes are shaved by the ice cutting blade and discharged from the ice discharge port as snow-like ice. At this time, the ice-breaking blade is in the in position, and the cutting block falls down to close the front part of the outlet, and together with the ice-breaking blade, forms an ice sliding surface, so that the ice cubes slide on the cutting block. On the other hand, to produce crushed ice, the ice cutting blade is moved back from the inner surface of the cutting case, and the cutting block is rotated around a rotation axis perpendicular to the sliding direction of the ice cubes.
The ice crushing blade is protruded into the cutting case to open the front of the closed outlet. The ice cubes thus slid by the ice rotor are crushed by the ice crushing blades and discharged from the ice crushing outlet. At this time, a multi-stage switching device was installed for the raising angle of the cutter block, so it was possible to switch the degree of protrusion of the ice-breaking blade into the inner surface of the cutting case, and accordingly change the degree of opening of the ice outlet on the ice-breaking side. As a result, crushed ice of a plurality of sizes and of relatively uniform sizes can be obtained. [Embodiment] A preferred embodiment of the present invention will be described below with reference to the drawings.
