BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric ice crusher which crushes ice blocks formed in a freezer into small pieces of ice.

[0002]

2. Description of the Related Art Conventionally, as an electric ice crusher, a case having an open upper end, a rotating shaft provided at the bottom of the case, a crushed body attached to the rotating shaft and rotated, There has been proposed a device provided with a charging cylinder having upper and lower openings at both ends and a lid provided on a case and closing an upper opening of the charging cylinder.

In the case of using an ice crusher of this type, a case is set on a main body having an electric motor in a cooking device such as a mixer, and a rotating shaft provided on the case is connected to an output shaft of the electric motor of the main body. . Then, the lid is removed from the case, ice blocks are put into the case from the upper end opening of the charging cylinder, and the lid is put on the case again. Thereafter, a switch provided on the main body is operated to drive the electric motor. The rotating shaft rotates the crushed body by driving the electric motor to crush the ice block to form ice pieces,
The ice pieces are discharged from the gap between the lower end opening of the charging cylinder and the crushed body into the case by the centrifugal force of the crushed body.

[0004]

However, the conventional ice crusher has the following problems.

The first point is as follows. In a conventional ice crusher, charging of ice blocks in a case, removal of ice pieces, and driving and stopping of an electric motor by operating a switch in a main body are independently performed independently of each other. For this reason, if the switch is turned on on the main unit side with the lid removed on the case side, the crushed body will rotate on the case side, and if there are ice blocks or ice chips inside the case, these will be There is a danger of accidents such as jumping out of the case and injuries of the hands if the user has their hands inside the case. The second point is as follows. Ice pieces obtained by crushing the ice block by rotating the crushed body are discharged into the case by the centrifugal force of the crushed body from a gap between the lower end opening of the charging cylinder and the crushed body. For this reason, the size of the ice piece is determined by the size of the gap between the opening at the lower end of the charging cylinder and the crushed body. In order to keep the ice pieces at a certain size, it is necessary to fix the charging cylinder at a certain position during rotation. Therefore, conventionally, the loading cylinder is fixed to a fixed position by the lid pressing the loading cylinder and fixing the lid to a fixing portion provided in the case. However, as described above, in the conventional ice crusher, since the handling operation on the case side and the handling operation on the main body side are performed independently of each other, the lid is not securely fixed to the case on the case side, so When the switch is turned on on the main body side in a state where the fixing of the cylinder is unstable, the charging cylinder rises due to the vibration of the rotation, and the size of the gap between the opening at the lower end of the charging cylinder and the crushed body fluctuates and the ice The size of the pieces fluctuates.

The third point is as follows. In order to fix the lid to the case as described above, it is necessary to specially form a lid fixing portion in the case and fix using the lid fixing portion,
This complicates the structure of the case and increases the manufacturing cost.

The present invention has been made in view of the above circumstances, and has a safe handling operation, is capable of stably obtaining ice pieces of a fixed size, and has a simplified case configuration. The purpose is to provide a crusher.

[0008]

In order to achieve the above object, an ice crusher according to the present invention comprises a motor and a main body having a switch incorporated in a drive circuit of the motor for turning on and off the drive circuit. The input cylinder receiving part is provided in combination with the main body, and the operating member enclosure wall
And parts are provided case, removably disposed inside of the case is placed on the closing tube receiving portion of the case
The outer peripheral portion is engaged with the operating member surrounding wall portion of the case.

The operating member is provided on the case so as to be movable up and down.
A switch actuating member inserted into the inside of the enclosure wall to turn on the switch when descending and to be constantly biased and displaced in a direction to turn off the switch, and provided so as to cover an upper end opening of the charging cylinder; And a lid that presses an upper end of the switch actuating member to turn on the switch while pressing a portion of the thrower placed on the thrower receiver of the case from above. .

Further, in the ice crusher of the present invention, the upper end of the switch operating member forms an inclined portion which becomes lower toward the side.

[0010]

In other words, the ice crusher of the present invention has the following operation based on the above-mentioned configuration.

[0011] In a state in which the lid for covering the charging cylinder is provided in the case, the user pushes the lid by hand to lower the switch operating member, and the switch operating member turns on the switch provided on the main body, so that the switch operating member is provided on the main body. The crushed body provided in the case is rotated by driving the electric motor. For this reason, the respective handling operations on the case side and the main body side are related to each other, and the electric motor of the main body is driven only when the lid put on the case is pressed,
When the lid is removed from the case, the electric motor on the main body does not drive. Therefore, the electric motor on the main body side is driven in a state where the lid is removed on the case side, and it is possible to prevent the occurrence of an accident such as an ice block or ice pieces jumping out of the case or injuring the user's hand. .

When the charging cylinder is arranged in the case, it is mounted on a charging cylinder receiving portion provided in the case. When the switch on the main body side is turned on by pressing the lid placed on the case, the lid presses the portion of the charging cylinder placed on the charging cylinder receiving portion from above. As a result, the charging cylinder is clamped and fixed, and it is possible to prevent floating when the electric motor is driven. Therefore, when the electric motor is driven, the size of the gap between the lower end opening of the charging cylinder and the crushed body can be kept constant, and the size of the ice pieces can be kept constant.

When the user closes the lid and turns on the switch, the lid simultaneously fixes the loading cylinder, so that there is no need to provide a special lid fixing portion for fixing the lid to the case. Can be prevented from becoming complicated and an increase in manufacturing cost. In addition, the operation of the engaging part of the charging cylinder and the case
The rotation of the loading cylinder is restricted by engagement with the wall surrounding the member.
By, for example, rotating the crushed body and throwing it into the inside of the charging cylinder
Receive force from rotating ice blocks and ice chips when breaking
Can prevent the input cylinder from rotating unnecessarily.
You.

Further, according to the present invention, since the inclined portion which becomes lower toward the edge is formed at the upper end of the switch operating member, even if an ice block is placed on the upper end of the switch operating member, it falls along the inclined portion. In addition, it is possible to prevent a situation in which the lid pushes down the switch operating member with the ice block interposed therebetween, that is, a situation in which the switch is turned on and the electric motor is driven before the lid does not sufficiently fix the input cylinder. Thus, it is possible to prevent a situation in which the charging cylinder rises during the crushing of the ice block and ice pieces of a certain size cannot be obtained as described above.

The operation of the thus-configured ice crusher will be described.

When actually crushing ice blocks, the ice blocks are set in the case 2 on the main body 1. In this case, the case 2 is placed on the upper end of the main body 1, and the claw 23 is positioned in the cutout 16 of the main body 1. Then, the case 2 is rotated to move the claw 23 into the notch 16 of the main body 1 and inside the retaining piece 17. At this time,
The recess 23 a of the claw 23 engages with the projection 18 of the notch 16. As a result, the case 2 is fixed to the main body 1 in the horizontal and vertical directions and does not come off. In this state,
The rotation shaft 10 of the main body 1 is located in the hole 22 of the inner cylindrical portion 20 of the case 2. The operating rod support 25 moves with the rotation of the case 3 and is located directly above the opening of the operation transmitting member support 14 at the upper end of the main body. For this reason, the lower end of the switch operation rod 26 supported by the operation rod support 25 of the case 2 abuts on the upper end of the operation transmission member 13 supported by the operation transmission member support 14 of the main body 1.

The crushed body 30 is arranged on the inner cylindrical portion 20 of the case 2, and the shaft fixing portion 31 a of the disk 31 is fixed to the rotating shaft 10. Further, the charging cylinder 3 is fitted into the case 2. The loading cylinder 3 is supported by the flange 3a abutting against the upper end of the rib 24 of the case 2. In this case, the notch 36 of the flange 3a is fitted into the operating rod support 25 of the case 2,
For positioning and detent for the. That is,
The operating rod support 25 of the base 2 is an operating member surrounding wall,

In this case, the lower end edge of the lid 4 is inserted into a gap formed between the upper end edge of the case 2 and the upper end edge of the charging cylinder 3 and is supported against the rib 35 of the flange 3 a of the charging cylinder 3. A part of the lower edge of the lid 4 inserted between the upper edge of the case 2 and the upper edge of the charging cylinder 3 has a switch operating rod 26 located at the upper end opening of the operating rod support 25.
Hit the top of

Then, the user presses the lid 4 from above by hand and applies a force downward. Then, the lid 4 is pushed as shown in FIG.
5, the switch operating rod 26 supported by the coil spring 15,
Press down against the spring force of 28. Switch operating rod 26
Moves downward (in a direction approaching the switch 11), the lower end (switch-side end) of the main body 1 directs the upper end of the operation transmission member 13 supported by the operation transmission member support portion 14 downward. Press. When the operation transmitting member 13 moves downward, the operator of the switch 12 is pressed.

Here, as shown in FIG. 14, the lower end of the switch operating rod 26 enters the rotation preventing member 39 formed on the upper end surface of the main body 1. For this reason, the case 2 is
Unnecessary pivoting in the direction deviating from is prevented.

Then, the switch 11 is turned on, and accordingly, the electric motor 7 is driven to rotate and the rotating shaft 10 is rotated. Accordingly, the disk 31 of the crushed body 30 fixed to the rotating shaft 10 rotates. The blade 32 rotates together with the disk 31, and the long blade 32 a and the short blade 32 b crush the ice block inside the charging cylinder 3 to form ice pieces. The ice pieces are discharged from the gap between the lower end of the charging cylinder 3 and the upper surface of the disk 31 by the rotation of the disk 31. The size of the ice piece is determined by the size of the gap between the lower end of the charging cylinder 3 and the upper surface of the disk 31. The released ice chips are sent out from the lower surface of the disk 31 and the lower end of the inner cylinder 20 of the case 2 to the ice chip extraction passage 5 by the wings 40 on the lower surface of the disk 31, and are directly transferred to the ice chip extraction passage 5. Will be sent out.

Here, when the lid 4 is pressed by hand to operate the switch 11, the flange 3a of the charging cylinder 3 is sandwiched between the lower end of the lid 4 and the rib 24 of the case 2, and the charging cylinder 3 is vertically moved. Since it is pinched and fixed so as not to move, the size of the gap between the lower end of the charging cylinder 3 and the upper surface of the disk 31 is kept constant, and the size of the obtained ice piece can be kept constant.

The obtained ice piece passes through the ice piece take-out passage body 5, hits the inner surface of the ice piece discharge port body 6, changes its direction, and is discharged from the lower end opening with its speed attenuated. As shown in FIG. 16, the ice piece discharge port 6 receives an ice piece discharged by placing an ice piece receiving tray 53 below the lower end opening.

When the formation of the ice pieces is continued, the ice pieces adhere to the inner surface of the ice piece outlet 6 and grow. Therefore,
The scraper 51 is rotated by the knob 52 to remove the ice chips attached to the inner surface of the ice chip discharge port body 6.

In this embodiment, the following effects can be obtained.

If the ice block rests on the upper end of the switch rod 26 and the lid 4 pushes down the switch rod 26 across the ice block, the lid 4 only pushes downward with a short distance corresponding to the thickness of the ice block. The switch operating rod 26 is lowered with a stroke necessary for operating the switch 11. That is, the switch 11 is turned on before the lid 4 sufficiently fixes the charging cylinder 3, and the electric motor rotates. For this reason, the input cylinder 3 may be lifted during the crushing of the ice block, and as described above, ice pieces of a certain size may not be obtained. However, the upper end of the switch operating rod 26 has an inclined portion 26a.
Is formed, even if an ice block is placed on the upper end of the switch operating rod 26, it falls along the inclined portion 26a. Therefore, it is possible to prevent the lid 4 from pushing down the switch operating rod 26 across the ice block. As a result, the above-described problem can be prevented from occurring.

The present invention is not limited to the above-described embodiment, but can be implemented in various modifications.

For example, the charging cylinder receiving portion provided in the case is not limited to the rib as in the embodiment, and may be a stepped portion. The charging cylinder receiving portion is not limited to the inside of the case, but may be provided outside and charged. You may receive a tube.

The form of the switch operating member is not limited to the embodiment.

The position where the upper end of the switch operating member contacts the lid is not limited to the upper side of the upper surface of the portion where the charging cylinder is supported by the charging cylinder receiving portion of the case but may be lower.

The form of the inclined portion at the upper end of the switch operating member is not limited to the embodiment.

The main body provided with the electric motor and the switch may be exclusively combined with the case as in the embodiment, may be integrally formed with the case, or may be a main body of a cooking device such as a mixer. .

[0057]

As described above, according to the ice crusher of the present invention, the user pushes the lid over the case with his / her hand to lower the switch operating rod, thereby turning on the switch provided on the main body. Since the motor provided on the main body is driven, the motor on the main body side can be driven with the lid removed on the case side, and the motor on the main body side can be driven with the lid removed on the case side. In addition, it is possible to prevent the occurrence of accidents such as an ice block or ice pieces jumping out of the case and an injury of a user's hand.

Further, when the switch on the main body side is turned on by pressing the cover placed on the case, the cover presses down the portion of the charging tube placed on the charging tube receiving portion of the case from above and fixes the charging tube. The size of ice chips obtained by crushing ice blocks by preventing the loading cylinder from rising when the motor is driven and maintaining the size of the gap between the lower end opening of the loading cylinder and the crushed body constant when the motor is driven Can be kept constant.

Further, when the user presses the lid to turn on the switch, the lid simultaneously fixes the loading cylinder.
Therefore, it is not necessary to provide a special lid fixing portion for fixing the lid to the case, so that the configuration of the case can be complicated and the manufacturing cost can be prevented from increasing. Also, the engaging portion of the charging cylinder
Rotation of the loading cylinder by engagement with the operating member enclosure wall of the case
By, for example, rotating the crushed body,
Ice blocks and ice that rotate when crushing ice blocks placed inside
Unnecessary rotation of the loading cylinder due to receiving force from one side
Can be blocked.

Further, since an inclined portion inclined toward the side edge is formed at the upper end of the switch operating member, even if an ice block is placed on the upper end of the switch operating member, it falls along the inclined portion. Pushing down the switch actuating member across the ice block, avoiding the occurrence of a situation in which the switch is turned on and the motor rotates before the lid does not sufficiently fix the loading tube, the loading tube rises during the crushing of the ice block. As described above, it is possible to prevent occurrence of a situation in which ice pieces of a certain size cannot be obtained.
