The fractured square ice includes varieties of sized of ice pieces. Fine ice pieces fall from a narrow gap (d) between the lower end of a container 20 lower part and a crusher plate 30 peripheral redge and stored in a storage part of the container 20 lower part. Alterna tively, the scattered square ice and ice pieces bounce upward along the second slanting surface 42 and forced to collide with a vertical surface 43 or collide with a stirring rib 45 after passing through the first slanting surface 41, and are scattered. The scat tered square ice, etc., slide down on the second slanting surface 42 and fall one the crusher plate 30, and again collide with the blade 34 and fractured. Accordingly, ice pieces enough finely fractured and stored in the storage part S.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electric water scraper that crushes ice using rotating blades.

[Conventional technology] A conventional electric ice scraper has a container that is removably placed on a main body that has a built-in electric motor, and a slice cutter placed inside the container is rotated by the electric motor to shave the pressed ice. Ta.

[Problems to be Solved by the Invention] However, in the conventional ice scraper, a cutting blade for cutting must be attached to the slice cutter, which causes a problem in that it is expensive to manufacture. Also, because the ice was scraped off from the edge in a thin layer,
There was also the problem that only a small amount of wood was scraped off at a time, and it took a long time to make the webs.

The present invention has been made in view of the above-mentioned problems, and two objects thereof are to provide an electric ice scraper that is inexpensive and capable of making ice cubes in a short time. In order to achieve the above object, the present invention provides a main body with a built-in electric motor, a container that is detachably placed on the main body and has a rotating shaft driven by the electric motor, and a container. The inner lower part is used as an accumulation part for accumulating crushed ice, and the ice is crushed by a charging cylinder provided above the storage part and a position facing the lower opening of the charging cylinder which is rotated by a rotating shaft. This electric ice scraper is equipped with a crusher plate having a blade for crushing, and the lower peripheral wall of the charging tube is inclined inward to form a narrow gap between the lower end of the lower peripheral wall and the peripheral edge of the crusher plate. It is characterized by this. [Operation] With the electric ice scraper having the above configuration, the ice thrown into the charging cylinder collides with the blade and is crushed by the rotation of the crusher plate. The crushed fine ice pieces fall through the narrow gap between the lower end of the input cylinder and the periphery of the crusher plate, and are accumulated in the accumulation area at the bottom of the container. On the other hand, the ice chips etc. thrown away by the blade are rolled up into the charging cylinder by the inclined surface,
It causes turbulence and falls. Then, it collides with the blade again and is shattered. [Embodiment] The present invention will be explained below based on the drawings.

As shown in FIGS. 1 and 2, the electric water web machine 10 includes a main body l2 containing an electric motor 1l, a container 20 placed f2 on the main body 12, a crusher plate 30 rotated by the electric motor 11, and a container f2. A charging cylinder 40 accommodated in the M 20 and an M
50. The container 20 has a skirt portion 21 below a bottom portion 20a, and has a bottomed cylindrical shape having a spout 22, a handle 23, and a pair of lid locking portions 24, 24 on the upper side surface. It is removably placed on the main body l2. Bottom part 20a
A cylindrical portion 25 that protrudes downward is provided at the center of the cylindrical portion 25 , and a rotating shaft 27 having a retaining portion 26 at the lower end is attached to the cylindrical portion 25 via a bearing 28 .

The rotating shaft 27 is connected to the electric motor 1 through the engaging portion 26.
It rotates by the driving force of l.

The crusher plate 30 has a disk shape with a shaft portion 31 on the back surface of the center portion, and a metal plate 32 is attached with a rivet 33. The sheet metal 32 is buried so that its upper surface is flush with the upper surface of the crusher plate 30,
It has a blade 34 formed by bending one end by press working. The crusher plate 30 is arranged such that the blade 34 has a twist angle a that is inward with respect to the tangent to the rotation direction.
It rises almost perpendicularly from the edge and has an acutely angled tip. In addition, a rotating shaft 2 is provided at the bottom of the shaft portion 31.
A notch 31a is formed for engaging with 7. The crusher plate 30 is connected to the rotating shaft 27 via the shaft portion 31.
is connected to. The charging cylinder 40 is a cylinder whose lower part is narrowed into two stages by a first inclined surface 4l forming a central peripheral wall and a second inclined surface 42 forming a lower peripheral wall. The surface 42 slopes inward and is continuous via a vertical surface 43. This first inclined surface 41 also serves as vibration prevention. Four reinforcing ribs 44 are formed on the outer peripheral surface of the charging cylinder 40, and a stirring rib 45 is provided at the upper part of the inner peripheral surface of the charging cylinder 40, the lower end of which touches the first inclined surface 4l. In addition, the stepped portion 46 formed at the upper part of the charging cylinder 40 is locked to the upper end of the container 20, so that the charging cylinder 40 is connected to the container 20.
It is installed above the storage section S in 0.
In this accumulation section S, crushed ice is accumulated. The crusher plate 30 is arranged at a position facing the lower opening 47 of the charging cylinder 40, and a narrow gap d is formed between the lower end of the second inclined surface 42 and the peripheral edge 30a of the crusher plate 30. The lid 50 has a downward flange 5l formed around the entire periphery, and a pair of opposing locking parts 52 formed on the outside of the flange 51. 52. Flange 5
1150 is placed over the input cylinder 40 so that 1150 is inscribed in the upper end of the input cylinder 40, and the locking parts 52 are locked by locking the locking parts 24, 24 for both lids. For this reason, the lid 5

0 and the charging cylinder 40 can be covered at the same time.

Next, an example of the operation of the electric ice scraper with the above configuration will be explained. As shown in FIG. 2, the container 20 is placed on the main body 12 with the rotating shaft 27 and the electric motor 11 connected via the engaging part 26, and a crusher plate 30 is placed above the rotating shaft 27 inside the container 20. Attach. Then, the charging cylinder 40 is inserted into the container 20 from the top of the container 20. The charging cylinder 40 inside the container 20 is fixed in a fitted state by reinforcing ribs 44 .

At this time, as shown in FIG. 3, the crusher plate 30 is positioned facing the lower opening 47 of the charging tube 40 so that the blade 34 enters the lower opening 47.

Next, for example, several pieces of ice cubes are introduced into the input tube 40 through the upper opening, and the lid 50 is locked. The thrown ice cubes are placed on the upper surface of the crusher plate 30.

Next, by turning on a switch (not shown) on the main body, the electric motor 11 rotates and the crusher plate 30 is rotated. Due to the centrifugal force accompanying the rotation of the crusher plate 30,
The ice cubes on the crusher plate 30 are drawn toward the second inclined surface 42, collide with the rotating blade 34, and are crushed or thrown away. The crushed ice cubes become pieces of wood of various sizes, and the fine ones fall through the narrow gap d between the lower end of the second slope 42 and the periphery of the crusher plate 30 and enter the container 2.
It is stored in the storage section S below 0. On the other hand, the ice cubes and ice pieces that are thrown away are thrown upward along the second slope 42, collide with the vertical surface 43, or collide with the stirring rib 45 via the first slope 4l, and are scattered. do. The scattered ice cubes and the like slide down the second slope 42, fall onto the crusher plate 30, collide with the blade 34 again, and are crushed.

Therefore, since ice cubes and the like are repeatedly crushed until they become fine pieces of wood that can pass through the gap d, sufficiently finely crushed webs are accumulated in the accumulation section S.
The size of the fine wood pieces is determined mainly by the height of the blade 34 and the gap d, so in order to make finer pieces of wood, the height of the blade and the gap d should be made smaller. In this way, the ice cubes and the like in the charging cylinder 40 are transferred to the second inclined surface 42.
The flow is guided upward by the flow, creating a turbulent state. Therefore, the frequency with which ice cubes etc. come into contact with the blade 34 increases, cutting efficiency is increased, and the ice cubes can be crushed in a short time.

In addition, since the blade 34 is formed by pressing the sheet metal 32, it can be made at low cost. [Effect] As explained above, the electric ice scraper according to the present invention has the lower circumferential wall of the charging cylinder inclined inward to form a narrow gap between the lower end of the lower circumferential wall and the circumferential edge of the crusher plate. Because of this, the introduced ice is guided upward by the lower peripheral wall, creating a turbulent flow. Therefore, the frequency of contact with the blade increases, cutting efficiency is increased, and webs can be created in a short time. In addition, since the ice is crushed to create webs, there is no need to use a slice cutter as in the past, making it cheaper.
