Description

[Detailed description of the invention] This invention relates to an ice scraper that makes shaved ice by cutting ice cubes made in a household refrigerator, etc., and its purpose is to quickly and easily set the roughness of ice shavings. To provide an ice scraper equipped with a cutter capable of

In conventional ice scrapers, when setting the roughness of the ice scraping, insert the cutter into a long hole drilled in the cutter, loosen the cutter fixing screw that is fastened to the tool rest, and then move the cutter edge to the tool rest. It was adjusted by making it protrude a predetermined amount from the surface.

However, this method requires that the cutter's cutting edge protrudes at an even height over its entire length, and that the cutting edge does not protrude or protrude insufficiently.As a result, the quality of ice cutting will be affected. Since I had to check the condition of the blade and readjust it when things went wrong, it was time consuming and troublesome to prepare the blade edge.
It has been difficult for women and others to easily adjust the cutter, as it is dangerous to touch the cutter when making adjustments.

The present invention eliminates the above-mentioned drawbacks and provides an ice shaver that is equipped with a cutter that allows even women and girls to quickly and easily set the roughness of ice scraping, and that can quickly make shaved ice of this roughness. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a box for an ice scraper, and inside is a box-shaped drive mechanism storage chamber 2 and a cylindrical cutting machine with a bottom through a partition wall. The chamber 3 is integrally formed.

Reference numeral 4 represents the legs of the ice scraper provided at the bottom of the box 1, and 5 represents an electric motor, which is coupled to a reduction gear 6 and installed in the drive machine storage chamber 2.

T is a protrusion protruding downward from the center back side of the inner bottom surface 3' of the cutting chamber 3 in the form of a cylinder or a prism. A fixed shaft 10 is provided with a support shaft 9 in the center, a lower end portion of which has a small diameter is embedded and fixed in the support shaft 9, and a screw portion is provided on the head having the same diameter as the support shaft 9.
is planted toward the inside of the cutting chamber 3.

Reference numeral 11 denotes a horizontally long cutter fitting groove recessed from the center to the periphery in the inner bottom surface 3' of the cutting chamber 3, and in the center thereof, there is a horizontally long discharge port 13 for discharging shaved ice shaved by a cutter 12, which will be described later. It is opened to

As shown in FIGS. 3P and 4, the cutter 12 is inserted into the center of a horizontally long metal plate having the same shape as the cutter fitting groove 11, with its front and back surfaces as shown in FIG. At the same location, cutting edges a and b with different blade heights are cut and raised along the discharge port 13 of the cutter fitting groove 11 with approximately the same length. In an actual case, as shown in Fig. 4, the cutting edge a is cut and raised so that its height is greater than the cutting height t of the cutting edge.
As a result, when the cutting edge a is used, ice can be roughly scraped, and on the other hand, when the cutting edge with a low blade height is used, the ice can be scraped finely.

Moreover, as shown in FIG. 3, the end of this cutter 11 has a
A cylindrical knob 14 is fitted on the fixed shaft 10 and the support shaft 9 that fixes the fixed shaft 10 so that the cutter 12 is fitted and held in the cutter fitting groove 11 by being fitted along the axis 1'fc to the fixed shaft 10 and the support shaft 9 that fixes the fixed shaft 10. It is fixed and protrudes with the same length in the vertical direction.

Reference numeral 15 denotes a cylindrical rotating hopper, and a bearing part 16 formed in a double cylinder shape in the center (the inner cylinder forming a part of the bearing part 16 is the same as the protruding length of the knob 14 protruding from the upper surface of the cutter 12). The cutting chamber 3V is cut by fitting the (shorter) into the fixed shaft 10 and screwing the hollow) 17 onto the threaded part of the head thereof. It can be rotated freely and can be put in and taken out freely.
When the gear 18 provided on the outer periphery of the upper open end is meshed with the final gear 6' of the reduction gear 6, the receiver rotates with the rotational force from the electric motor 5.

The rotating hopper 15 has a ceiling surface between the outer peripheral wall and the bearing part 16 that is gradually inclined downward from one end communicating with the water socket 19 in a direction opposite to the rotating direction of the rotating hopper 15. A water plate 21 forming a spiral passage 20 therein is provided in a part.

22 is a cover which has an ice inlet 23 opened at the top and is detachably placed over the cutting chamber 3rc, and 24 is a power switch.

Next, to explain the operation, when roughly shaving ice, the cutter 12 is placed on the fixed shaft 10 with the cylindrical knob 14 provided at the end of the cutter 12, with the high blade height and the raised cutting edge a facing upward. It is inserted into the cutter fitting groove 11 provided on the inner bottom surface 3' of the cutting chamber 3 through the cutter.

At this time, the knob 14 provided on the cutter 12 is fitted across the fixed shaft 10 and the support shaft 9 to hold the cutter 12 in the cutter fitting groove 11Vc.

(At this time, the cutting edge has entered the discharge port 13Vc.) In this state, the rotating hopper 15 is connected to the fixed shaft 10 with its bearing portion 16.
When the nut 17 is screwed onto the head of the fixed shaft 10 after the gear 18 and the reduction gear 6 are meshed with each other, the rotary hopper 15 is rotatably supported by the fixed shaft 10v.

In this state, a cover 22 is placed over the cutting chamber 3 to cover the upper part of the rotary hopper 15, and then a power switch 24 is turned on to start the electric motor 5, and its rotational force is transmitted to the rotary hopper 15VC via the reduction gear 6.

Ice inlet 23 of cover 22 after rotation of rotating hopper -15
When ice cubes are put into the rotating hopper 15, the ice cubes fall onto the water plate 21 of the rotating hopper 15, enter the rotating hopper 15 through the water socket 19, and while being pressed by the water plate 21, the ice blocks fall onto the inner bottom surface 3 of the cutting chamber 3. ' The cutting edge aK of the cutter 12 touches and cuts.

At this time, the ice block is roughly cut because the cutting edge a of the cutter 12 is higher than the cutting edge.

The roughly shaved ice pieces are received in a container 25 such as a saucer through a discharge port 13 from the gap between the cutting edges a and b of the cutter 12.

The cutter 12 is attached to the cutter fitting groove 11 through a knob 14 across the fixed shaft 10 and the support shaft 9, and the inner cylinder of the bearing part 16 of the rotary hopper 15 is attached to the knob 14. Since the outer cylinder of the bearing part 16 and the lower end of the outer circumferential wall of the rotary hopper 15 are in sliding contact with each other in a state surrounding one cutting edge of the cutter 12, the cutter 12 is in a cutting chamber when cutting ice blocks. 3, it is held in the cutter fitting groove 11 and the ice block can be cut smoothly.

In the case of shaved ice with a fine roughness, after removing the rotary hopper 15 from the cutting chamber 3, turn the knob 14 of the cutter 12.
between your fingers, pull the cutter 12 upward from the cutter fitting groove 11 along the fixed shaft 10, pull out the knob 14 from the fixed shaft 10, and then turn the cutter 12 over so that the lower cutting edge is aligned with the top 1. Rotate cutter 12 knob 14
is attached to the fixed shaft 10, and the cutter 12 is set in the cutter fitting groove 11 with its cutting edge facing upward.

In this state, the rotary hopper 15 and cover 22 are attached to the cutting chamber 3, and the rotary hopper 15 is driven, and the ice cubes are guided by the cutter 121 and cut with the cutting edge bVr- by the rotary hopper 150 revolutions. can make finer shaved ice than the blade tip a.

To set the roughness of the cut, the cutter 12 can be simply inserted into the cutter fitting groove 11 with either the higher or lower edge facing upward, and can be handled using the cylindrical knob 14 provided on the cutter 12'rc. Since the cutter 12 can be operated by holding it, there is no need for the fingers to touch the cutting edge when operating the cutter 12, making it easy to set the cutting roughness.

And it can be done safely.

Incidentally, instead of implanting the support shaft 9rc, the fixed shaft 10 may be fixed directly to the bottom of the protrusion 7 by screws etc. by removing the support shaft 9, and may be made to stand upright in the cutting chamber 3. shaped knob 14
It is not necessary to protrude the same length on both sides of the cutter 12, and if one of the knobs 14 does not fit into the circular groove 8, the cutter 1
2 is raised on the inner bottom surface 3' of the cutting chamber 3, or the upper end of the bearing part 16 is pushed up from the fixed shaft 10, making it impossible to pivot the rotating hopper 15 to the fixed shaft 10. It goes without saying that the knob 14 may be provided with a length that allows it to be held between the fingers so that it can be received by the cutter 12.

As mentioned above, the cutter for cutting sea urchins and ice blocks has cutting edges with different heights on both sides, and a cylindrical knob is integrally attached to the end of the cutter. By using a double-sided rc cutter and flipping it over depending on the roughness of the cut, you can make shaved ice roughly or finely with a single cutter. This invention has cutting edges with different heights on the front and back sides of the cutter, so when cutting ice roughly, use the higher blade edge,
On the other hand, when shaving ice into small pieces, you can easily create shaved ice with the desired roughness by using a low-height cutting edge.

In addition, the cutting roughness setting is completely different from the conventional method, which adjusts the degree of protrusion of the cutter edge by loosening the cutter fixing screw.In this case, two types of cutters with different blade heights are set in advance. Since the cutting edge of the cutter is angled, there is no need to adjust the height of the cutting edge. When cutting ice, you can select either a high cutting edge or a low cutting edge and simply place the cutter itself on the bottom of the cutting chamber. Since it is only necessary to fit the cutter into the provided cutter fitting groove, there is no need to adjust the cutting edge of the cutter at all, and therefore, even women and girls can quickly and easily set the height of the cutter's blade when using the water pump.

Moreover, when cutting ice cubes, the cutting edges with different heights are cut and raised in opposite directions at the same location on the cutter. There is no possibility that the ice block that gets stuck in the hole will be crushed and crushed without being cut by the cutter, so this idea uses cutting edges with different heights on the front and back of the cutter, cutting in opposite directions at the same place. Therefore, ice cubes can be cut smoothly without being crushed.

In addition, the cutter can be handled by holding it with a knob protruding from one end of the cutter, allowing the cutter to be inserted into and taken out of the cutter fitting groove without touching the cutting edge. can be handled safely and reliably.

Furthermore, the cutter can be easily fitted into the cutter fitting groove in one motion by passing its knob through the fixed shaft.Furthermore, the cutter can be fitted into the cutter fitting groove and housed in the rotating hopper. Since the lower edges of the bearing portion and the outer peripheral wall of the rotating hopper are slidably mounted on the cutter in a state surrounding one of the cutting edges of the cutter, the cutter rotates while cutting the ice. Since the lower edge of the rotating hopper is held so that it does not float up from the cutter fitting groove, the cutter fitting groove does not spring up during ice cutting and make cutting difficult. The work can be carried out smoothly, and since the cutter is held by the rotating hopper without lifting up, there is no need for a set screw to hold the cutter, and the cutter can be secured using a screw. This has excellent practical effects, such as eliminating the need for
