Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ice shaver, and more particularly to an ice shaver whose cover has a soundproof structure.

[Prior Art] The structure of an ice shaver is shown in the sectional view of FIG. The cutting case 12, which is fixed to a support column erected on the machine stand 40 at the peripheral support portion, has an inverted conical shape, and inside the cutting case 12, a rotary blade 10 with a plurality of blades is driven by a motor 18, and the case is It is fixed to a rotating shaft supported by 12. A shaved ice outlet 24 is open in the cutting case 12, and an ice cutting blade and an ice crushing blade 28 are exposed thereto.

A rotary ring 32 adjacent to the upper edge of the cutting case 12 is fixed to the upper end surface of the rotary blade 10, and a cylindrical rotary hopper 34 whose diameter decreases upwardly is attached to this rotary ring 32 and rotates. It rotates together with the wing 10. The cutting case 12 has a front cover 36 and a rear cover 38 with the peripheral edge of the cutting case 12 as an upper end and covering between the machine bases, and a head cover on the upper part of the cutting case 12.

In the ice cutter having such a structure, noise during ice cutting operations is transmitted from the cutting case 12, which is the source of noise, to the outside via the front cover 36, the rear cover 38, and the head cover. As a countermeasure against this problem, as described in Japanese Utility Model Application Publication No. 52-123577, the outer surface of the hopper 34 of the present invention, which corresponds to the cover 13 in this publication, is covered with a sound deadening material. However, in this case, there is a problem in that noise generated by vibrations transmitted to the respective covers of the head is added, and it is not possible to prevent outward propagation of this noise.

[Problems to be solved by the invention] This invention was made in view of the above-mentioned problems such as the generation of noise in conventional ice-shaving machines. The purpose is to erase this in a confined state.

[Means for Solving the Problems] The ice shaver according to the present invention has a damping material and a sound absorbing material affixed to the inner surfaces of the front cover, rear cover, and head cover that cover the outer periphery of the machine body.

[Function] This ice cutting machine has damping material attached to the front cover, rear cover, and head cover, so vibrations and noise transmitted from the cutting case are absorbed by the damping material and sound absorbing material attached to these covers. This makes the ice shaver extremely quiet during operation.

[Embodiments] Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side sectional view showing an embodiment of the present invention. In the figure, a cutting case 12 fixed to a support column (not shown) erected on a machine base 40 at a peripheral support portion has an inverted conical shape, and inside the cutting case 12, a rotary blade 10 with a plurality of blades is installed to drive a motor 18. The rotary shaft 14 is driven by a rotating shaft 14 and is supported by the case 12. A shaved ice outlet 24 is open in the cutting case 12, and an ice cutting blade and an ice crushing blade 28 are exposed thereto.

A rotary ring 32 adjacent to the upper edge of the cutting case 12 is fixed to the upper end surface of the rotary blade 10, and a cylindrical rotary hopper 34 whose diameter decreases upwardly is attached to this rotary ring 32 and rotates. It rotates together with the wing 10. The cutting case 12 has a front cover 36 and a rear cover 38 with the peripheral edge of the cutting case 12 as an upper end and covering between the machine bases, and a head cover 42 on the upper part of the cutting case 12.

A vibration damping material 44 of approximately 2 mm in thickness was adhered as a first layer to the back surfaces of the front cover 36, rear cover 38, and head cover 42. As the vibration damping material 44, it is preferable to use a polymeric viscoelastic material that has an excellent vibration damping function. Next, as a second layer, a sound absorbing material 46 of about 10 mm was pasted on the damping material 44. As the sound absorbing material 46, it is preferable to use foamed polyurethane.

Ice cubes were actually put into the ice shaver of this embodiment having the above configuration and the ice was shaved, and the noise was compared with that of a conventional ice shaver. The ice shaver of this example produced significantly less noise than conventional ice shavers, and was very quiet during operation. Note that the cover may be divided as appropriate for convenient attachment and removal.

[Effects of the invention] As explained above, the ice shaver has damping material affixed to the inner surfaces of the front cover, rear cover, and head cover, and a sound absorbing material affixed to the inner surfaces thereof. The noise generated within the ice cutting machine is absorbed by the sound absorbing material, and the vibration from the cutting case is absorbed by the damping material when it is transmitted to the outermost covers. Since all of these actions are performed within the ice shaver, the noise and vibrations transmitted to the outside are significantly reduced, resulting in an excellent effect of extremely low noise during operation of the ice shaver.
