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 adjust the roughness of ice shavings. The purpose is to provide an ice scraper equipped with a cutter.

In conventional ice scrapers, to adjust the roughness of the ice scraping, insert the long hole drilled into the cutter and loosen the screw that fastens the cutter to one cutter. Adjustments were made by touching the surface by a predetermined amount.

However, with this method, if you do not make the cutter's cutting edge protrude at an even height over its entire length, and make sure that the cutting edge does not stick out too much, the quality of the ice cutting will be affected. In the worst case, readjustment is required, so adjusting the amount of protrusion of the cutting edge is time-consuming and troublesome.

Moreover, it was extremely difficult to adjust the cutting edge, and there was a problem that women and girls in particular were unable to do this easily.

The present invention eliminates the above-mentioned drawbacks and is equipped with a cutter that allows even women and girls to quickly and easily adjust the roughness of the shaved ice, thereby making it possible to quickly and easily make shaved ice with the roughness of the shaved ice. The present invention will be explained below using an example in which the present invention is applied to an electric ice scraper. 1 is the image body of the electric ice scraper;
As shown in FIG. 1, a drive mechanism storage chamber 2 and a rotary hopper storage chamber 3 having a cylindrical shape with a bottom are integrally formed.

Reference numeral 4 denotes the legs of an ice scraper installed vertically at the bottom of the picture body 1, and 5 is an electric motor installed in the drive mechanism storage chamber 2 of the picture body 1. The final gear 6' is stored in the rotating hopper in this electric motor 5. A reduction gear 6 exposed in the chamber 3 is drivingly connected.

Reference numeral 7 denotes a fixed shaft whose lower end is buried and fixed in the center of the bottom surface 3' of the rotary hopper storage chamber 3 so as to stand upright, and a screw portion is screwed into the head of the fixed shaft.

As shown in FIG. 2, reference numeral 8 denotes a cutter mounting groove which is recessed horizontally from the center of the bottom surface 3' toward the periphery, including the mounting position of the fixed shaft 7, on the bottom surface 3' of the rotating hopper storage chamber 3. In the center of the cutter mounting groove 8, an ice chip outlet 9 is bored horizontally along its longitudinal direction.

Reference numeral 10 denotes a horizontally long plate-shaped cutter having the same shape as the cutter mounting groove 8, which is removably mounted in the cutter mounting groove 8, and its cutting edge ayb extends its entire length as shown in FIGS. 2 and 3. The cutter has the same length as the longitudinal direction of the discharge port 9, and is formed by cutting horizontally at a required angle on both sides of the cutter, and the height of the cutting edges a and b from the cutter reference plane X is as shown in Fig. 3. The cutter 10 is formed so that the height of the cutting edge a is greater than the height l of the cutting edge.
When scraping ice with the cutting edge a, it is possible to scrape roughly, and conversely, when scraping with the cutting edge, the amount of cutting is reduced and it is possible to scrape finely.

The cutter 10 can be installed by fitting the engagement hole 11 drilled at one end (the right end in FIG. can be attached to the bottom surface 3' of the rotating hopper storage chamber 3 in a protruding state.

12 is a cylindrical rotating hopper for holding ice;
By fitting the bearing portion 13 provided at the center onto the fixed shaft 7 and screwing a nut onto the head thereof, the hopper is rotatably supported on the fixed shaft 7 and stored in the rotating hopper storage chamber 3.

At this time, the rotary hopper 12 is slidably mounted on the cutter 10-1 in a state surrounding one of the cutting edges.

Further, the rotary hopper 12 is rotated by receiving the rotational force from the electric motor 5 when a gear 14 formed on the outer periphery of its upper open end is meshed with the final gear 6' of the reduction gear 6.

The rotating hopper 12 has an outer peripheral wall and a bearing portion 1.
3, a lower surface opposite to the bottom surface 3' of the rotating hopper storage chamber 3 is opened, and the ceiling surface is gradually inclined downward from one end connected to the water socket 15 in a direction opposite to the direction of rotation of the rotating hopper 12. An ice pressing plate 17 is integrally provided to form a spiral passage 16.

Reference numeral 18 is a cover provided with an ice inlet 19 at the top and removably attached to the rotating hopper storage chamber 3. Reference numeral 20 is a switch for opening and closing the motor circuit.

Next, the operation will be described. First, when roughly shaving ice, the cutter 10 is fitted into the cutter mounting groove 8 with the high blade edge a facing upward.

After that, the rotary hopper 12 is stored in the rotary hopper storage chamber 3, and the gear 14 and the reduction gear 6 are meshed, and then the fixed shaft 7
The rotary hopper 12 is pivoted to the fixed shaft 7 by screwing a nut thereon so as to rotate about the fixed shaft 7.

In this state, the top of the rotary hopper 12 is covered with a cover 18, a switch 20 is turned on to start the electric motor 5, and the rotational force is transmitted to the rotary hopper 12 via the reduction gear 6 to rotate it.

Then, when you put ice cubes into the ice inlet 19 of the cover 18,
The ice block falls onto the ice holding plate 17 of the rotating hopper 12, enters the spiral passage 16 from the water socket 15, and then passes through the ice holding plate 1.
It slides on the bottom surface of the rotating hopper storage chamber 3 while being pressed by the cutter 7, and is roughly cut by touching the cutting edge a of the cutter 10.

The roughly shaved ice pieces pass through the gap between the cutting edges a and b of the cutter 10 and are received from the outlet 9 into a container 21 such as a saucer placed below.

At this time, as the rotary hopper 12 rotates, the ice cubes, which become smaller as they are cut, are continuously pressed downward by the inclined ice presser plate 1γ, and are sent to the depths of the ice presser plate 17, and then cut to the end by the cutter 10. You can make shaved ice with rough edges.

In addition, the cutter 10 has an engagement hole 11 provided at one end that is fitted into the fixed shaft 7, and both ends of the cutter 10 in the longitudinal direction are connected to the bearing part 13 of the rotary hopper 12 and the rotary hopper 11, respectively. Since the cutter 10 is slidably pressed down by the peripheral edge, even if the ice block touches the cutting edge a, the cutter 10 is held in the cutter attachment groove 8 without jumping up and can smoothly cut the ice block.

If you want to make fine shaved ice, use cutter 10.
Turn the cutter 1 over and set the cutter 1 with the lower cutting edge facing upward.
0 is fitted into the fixed shaft 7, and the cutter 10 is lowered along the fixed shaft 7 and fitted into the cutter mounting groove 8.

As a result, the cutter 10 is installed in the rotary hopper storage chamber 3 with the cutting edge facing upward, and then the rotary hopper 12 is stored in the rotary hopper storage chamber 3, the nut is tightened on the fixed shaft 7, and the cover 18 is closed. It covers the rotating hopper storage chamber 3.

In this state, when the switch 20 is turned on and the rotary hopper 12 is turned, ice cubes are thrown into the rotary hopper 12 from the ice inlet 19 of the cover 18 and cut by the cutting edge of the cutter 10, the ice cubes are finer than the cutting edge a. Because it is cut,
You can make finely shaved ice.

Although this proposal has been explained with reference to an example implemented in an electric water scraper, a manual ice scraper can also be used by recessing a cutter mounting groove on the top surface of one cutter with an ice chip outlet in the center. In this cutter mounting groove, a cutter with cutting edges with different heights cut up and down is installed in a reversible manner.
The present invention can be applied even if coarse shaved ice or finely shaved ice is made.

As described above, the present invention is to provide a cutter for cutting ice cubes by cutting and raising the cutting edge of the cutter with different heights in the vertical direction, and to use a cutter having cutting edges with different heights on both sides as needed. By turning the ice over and using it, you can roughly or finely shave the ice cubes with a single cutter to make Konomi shaved ice. This is completely different from adjusting the amount of protrusion of the cutting edge by loosening the screws that fix it.In this case, when cutting ice, the cutting edge is raised by setting different blade heights on the front and back sides of the cutter. Since a cutter is used, there is no need to loosen screws and adjust the amount of protrusion of the cutting edge, which is required in the conventional method.The cutter is rotated in the hopper storage chamber so that the cutting edge is in contact with the ice according to the cutting process. Since it only needs to fit into the cutter mounting groove of the cutter, the roughness of the ice can be set quickly and easily.

Moreover, in this case, the cutter has two types of cutting edges with different heights cut and raised in opposite directions at the same place, so there is no amount of filler to adjust the cutting edge, and the cutting edge can be set at a higher height depending on the roughness of the ice. Since the roughness of the ice can be easily set by women and men, it is only necessary to arbitrarily select the higher or lower one.

In addition, in this case, all you need to do is to engage the engagement hole provided in the cutter with the fixed shaft and fit the cutter into the cutter installation groove recessed in the bottom of the rotating hopper storage chamber, so the installation of the cutter can be done in one operation. Moreover, by fitting the cutter itself into the cutter mounting groove, there is no need to use screws to fix the cutter as in the past.In addition, while cutting ice, Since the rotary hopper is received and held by the lower edge of the rotating hopper so as not to float out of the cutter fitting groove, the cutter can be economically installed in the cutter fitting groove without using any special fixing means. Since the cutter is received by the rotating hopper and held in the cutter mounting groove without floating up, the ice cutting operation can be performed smoothly.

In this way, the ice scraper of the present invention is very convenient because it is possible to install the cutter and set the cutting roughness in one operation.Moreover, the cutting roughness can be set by changing the height of the cutting edge. Since the cutter is installed in a horizontal position, the cutter can be set by simply turning the cutter over.Furthermore, the cutter can be fixed by simply fitting it into the cutter mounting groove, without using any fixing means such as screws. The proposed ice scraper has a number of remarkable practical effects, such as being able to be installed without interfering with ice cutting.
