[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric ice crusher that crushes ice cubes produced in a freezer or the like into small pieces of ice.

0002

[Prior Art] Conventionally, an electric ice crusher includes a case with an open top end, a rotating shaft provided at the bottom of the case, a crushing body attached to the rotating shaft and rotated, and a crusher mounted inside the case. A device has been proposed that includes a disposed charging cylinder with openings at both upper and lower ends, and a lid provided in the case to close the upper end opening of the charging cylinder.

When using this type of ice crusher, the case is set on the main body of a cooking device such as a mixer, which is equipped with an electric motor, and the rotating shaft provided in the case is connected to the output shaft of the electric motor of the main body. . Then, the lid is removed from the case, ice cubes are poured into the case through the upper opening of the input cylinder, and the lid is placed over the case again. After that, operate the switch provided on the main body to drive the electric motor. Driven by an electric motor, the rotating shaft rotates the crushing body to crush the ice blocks into ice pieces,
The ice pieces are discharged into the case through the gap between the lower end opening of the input cylinder and the crushed body by the centrifugal force of the crushed body.

0004

However, this conventional ice crusher has the following problems.

The first point is as follows. In a conventional ice crusher, the operations of inserting ice cubes into a case, taking out ice pieces, and driving and stopping an electric motor by operating a switch in the main body are performed independently without being related to each other. For this reason, if you turn on the switch on the main unit with the lid removed on the case side, the crushing body will rotate on the case side, and if there are ice blocks or pieces of ice inside the case, these will be removed from the case. There is a risk that the user may fly out of the case, and if the user has his or her hand inside the case, there is a risk of injury to the user's hand. The second point is as follows. The ice pieces obtained by crushing the ice block by the rotation of the crushing body are discharged into the case through the gap between the lower end opening of the input cylinder and the crushing body by the centrifugal force of the crushing body. Therefore, the size of the ice pieces is determined by the size of the gap between the lower end opening of the input cylinder and the crushed body. In order to maintain ice pieces at a constant size, it is necessary to keep the charging tube fixed in a constant position during rotation. Therefore, conventionally, the lid presses the charging cylinder and the lid is fixed to a fixing part provided in the case, so that the charging cylinder is fixed at a fixed position. However, as mentioned above, in conventional ice crushers, the handling operations on the case side and the handling operations on the main body side are performed without any relation to each other, and the lid is not securely fixed to the case on the case side. If you turn on the switch on the main unit while the cylinder is not fixed, the vibration of the rotation will cause the charging cylinder to float up, and the size of the gap between the opening at the bottom of the charging cylinder and the crushed object will change, causing ice to form. The size of the pieces will change.

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 part on the case and fix it using this lid fixing part.
This results in an increase in the complexity of the structure of the case and an increase in manufacturing costs.

The present invention has been made based on the above circumstances, and is an ice cream that is safe to handle, can stably obtain ice pieces of a certain size, and has a simplified case structure. The purpose is to provide a crusher.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the ice crusher of the present invention includes a main body having an electric motor and a switch incorporated in a drive circuit of the motor to turn the drive circuit on and off; A case combined with the main body and provided with a charging cylinder receiving part, a charging cylinder with openings at both upper and lower ends placed on the charging cylinder receiving part of this case and arranged inside the case, and a charging cylinder with openings at both upper and lower ends of the charging cylinder. A crushing body that is provided inside the case and rotates by receiving power from the electric motor; and a crushing body that is provided in the case so as to be movable up and down, turns on the switch when descending, and constantly applies a biasing force to the switch. The switch actuating member is displaced in the direction of turning off the input cylinder, and presses from above the portion of the input cylinder that covers the upper end opening of the input cylinder and is placed on the input cylinder receiver of the case, and operates the switch. The device is characterized by comprising a lid that turns on the switch by pressing the upper end of the member.

Furthermore, in the ice crusher of the present invention, the upper end of the switch actuating member forms an inclined portion that becomes lower toward the side.

0010

[Function] That is, the ice crusher of the present invention has the following functions based on the above structure.

[0011] With the lid covering the charging tube provided on the case, the user presses the lid with his or her hand to lower the switch actuating member, and the switch actuating member turns on the switch provided on the main body. The crusher installed in the case is rotated by driving the electric motor. For this reason, each handling operation on the case side and the main body side is related to each other, and the electric motor of the main body is driven only when the lid placed on the case is pressed.
The electric motor on the main body side does not operate when the lid is removed on the case side. Therefore, it is possible to prevent the occurrence of accidents such as the electric motor on the main body side operating with the lid removed on the case side, causing ice cubes and pieces of ice inside the case to fly out, or injuring the user's hands. .

When the charging cylinder is placed in the case, it is placed on a charging cylinder receiving portion provided in the case. When the lid placed on the case is pressed and the switch on the main body is turned on, the lid presses the portion of the charging tube placed on the loading tube receiving portion from above. As a result, the charging tube is clamped and fixed, and it is possible to prevent it from 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 input cylinder and the crushing body can be kept constant, and the size of the ice pieces can be kept constant.

When the user presses the lid to turn on the switch, the lid fixes the charging cylinder at the same time, so there is no need to provide a special lid fixing part on the case to fix the lid to the case, and the case is fixed. It is possible to eliminate the complexity of the configuration and increase in manufacturing costs.

Furthermore, in the present invention, since the upper end of the switch actuating member is formed with a slope that becomes lower toward the edge, even if an ice block is placed on the upper end of the switch actuating member, it will not fall along the slope. It is possible to prevent a situation in which the lid pinches an ice cube and pushes down the switch actuating member, that is, a situation in which the switch is turned on and the electric motor is driven before the lid has sufficiently fixed the charging cylinder. This can prevent the occurrence of a situation where the charging tube floats up during the crushing of the ice block and ice pieces of a certain size cannot be obtained as described above.

[0015]

On the other hand, inside the case 2, a crushing body 30 is disposed at the bottom of the inner cylindrical portion 20. This crushed body 30 is shown in FIG.
As shown in FIGS. 4 and 9, it is composed of a disk 31 made of synthetic resin or the like, and a metal blade 32 attached to the upper surface of the disk 31 with bolts 33. The disk 31 has a shaft fixing portion 31a formed on its lower surface, and a hole 31b into which a finger is inserted during attachment and detachment. Disc 31
is arranged horizontally, and the shaft fixing part 31a is fixed to the upper end of the rotating shaft 10 provided in the main body 1. In this case, the shaft fixing part 31
A member 31 to be hooked to the wedge member 10a of the rotating shaft 10
c is provided, and the wedge member 10a is bent using its spring property to latch the member 31c. When removing the disk 31, the wedge member 10a is also bent and removed from the member 31c. The blade body 32 extends diametrically across the center of the disc 31, and has a long blade 32a that reaches the outer periphery of the disc 31 and runs along the diameter at one end, and a long blade 32a that extends in the diametrical direction at the other end. A short blade 32b is formed along the tangential direction of the disc 31 and is lower in height and located on the inner peripheral side than the long blade 32a. Note that a plurality of wings 40 are provided radially on the outer peripheral portion of the lower surface of the disk 31.

As shown in FIGS. 1 to 4, a charging cylinder 3 is fitted inside the case 2 from above. As shown in FIG. 12, the part of the charging cylinder 3 that fits inside the inner cylinder part 20 of the case 2 has an outer diameter that is approximately the same size as the inner diameter of the inner cylinder part 20, and an inner diameter that is the same as that of the blade body 32. Short blade 32
It is larger than the rotating diameter of b. The portion of the charging tube 3 above the portion that fits inside the inner cylinder portion 20 of the case 2 has a tapered portion whose diameter gradually increases toward the upper end. A flange 3a is formed on the upper outer circumference of this tapered portion. As shown in FIG. 14, this flange 3a has a notch 36 into which the actuating rod support portion 25 of the case 2 fits, and as shown in FIG. 13, a plurality of ribs 35 are formed on the upper surface of the flange 3a. It is formed.

As shown in FIGS. 1, 2 and 3, this flange 3a abuts against the upper end of a rib 24 formed inside the outer cylindrical portion 19 of the case 2, thereby preventing the charging tube 3 from falling downward. is being prevented. The lower end of the charging cylinder 3 and the crushed body 30
A gap of a certain size is formed between the long blade 32a of the blade body 32 and the long blade 32a. Note that a cap 34 having an opening 34a serving as an ice chip inlet is fitted and fixed to the upper end opening of the input cylinder 3.

As shown in FIGS. 1 to 3 and 11, the lid 4 is fitted into the upper opening of the case 2 and covers the charging tube 3 and the cap 34 from above. When the lid 4 is fitted into the upper opening of the case 2, its lower edge is inserted into the gap formed between the upper edge of the case 2 and the upper edge of the charging cylinder 3, as shown in FIG. It is supported against the rib 35 of the flange 3a of the cylinder 3.

Here, the upper end of the switch actuating rod 26 protruding from the upper end opening of the actuating rod support portion 25 is located in the gap between the upper end edge of the case 2 and the lower end edge of the charging cylinder 3. Further, the thickness of the lower end edge of the lid 4 is smaller than the thickness of the upper end opening of the actuating rod support portion 25. Therefore, when the lid 4 is fitted into the upper end opening of the case 2 as shown in FIGS. 1 and 2, it fits between the upper end edge of the case 2 and the lower end edge of the charging tube 3, as shown in FIG. 15. A portion of the lower edge of the lid 4 is attached to the operating rod support portion 25.
This corresponds to the upper end of the switch operating rod 26 located at the upper end opening. Here, since the spring force of the compression coil spring 28 provided in the case 2 and the compression coil spring 15 provided in the main body 1 described above is larger than the load of the operation transmission members 13 and 26 and the lid 4, the operation rod support portion 25 The switch operating rod 26 does not descend. Therefore, when the lid 4 is fitted into the upper opening of the case 2, the lid 4 is inclined as shown in FIG.

Note that 38 in the figure is a power cord connected to the circuit of the electric motor 7 of the main body 1.

The operation of the ice crusher constructed in this way will be explained.

When actually crushing ice blocks, the main body 1 is set in the case 2. In this case, the case 2 is placed on the upper end of the main body 1, and the claws 23 are positioned in the notches 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 23a of the claw 23 engages with the protrusion 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 will not come off. In this state, the rotating shaft 10 of the main body 1 is located in the hole 22 of the inner cylinder part 20 of the case 2. Then, as the case 3 rotates, the operating rod support part 2
5 is moved and positioned directly above the opening of the operation transmission member support portion 14 at the upper end of the main body. Therefore, the lower end of the switch actuating rod 26 supported by the actuating rod support part 25 of the case 2 abuts against the upper end of the actuation transmitting member 13 supported by the actuating transmitting member support part 14 of the main body 1 .

The crushing body 30 is placed in the inner cylindrical portion 20 of the case 2, and the shaft fixing portion 31a of the disk 31 is fixed to the rotating shaft 10. Furthermore, the charging cylinder 3 is fitted inside the case 2. The flange 3a of the charging cylinder 3 abuts against the upper end of the rib 24 of the case 2 and is supported. In this case, the notch 3 of the flange 3a
6 is fitted into the actuating rod support portion 25 of the case 2 to position it in the charging cylinder 3 and prevent it from rotating.

[0038] Opening 34 of cap 34 of charging cylinder 3
Insert into the charging cylinder 3 from a.

After that, as shown in FIG. 1, the lid 4 is attached to the case 2.
Fits into the upper end opening of. In this case, the lower end edge of the lid 4 is inserted into the 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 3a of the charging cylinder 3. In addition, 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 is attached to the switch operating rod 26 located at the upper opening of the operating rod support part 25.
It hits the top of the .

[0040] Then, the user presses the lid 4 from above with his/her hand and applies force downward. Then, as shown in FIG.
The switch actuating rod 26 supported by the coil spring 15,
Push down against the spring force of 28. Switch operating rod 26
When it moves downward (in the direction approaching the switch 11), its lower end (end on the switch side) directs the upper end of the actuation transmitting member 13 supported by the actuation transmitting member support part 14 of the main body 1 downward. and press. When the operation transmission member 13 moves downward, the operator of the switch 12 is pressed.

Here, as shown in FIG. 14, the lower end of the switch actuating rod 26 enters into the rotation preventing member 39 formed on the upper end surface of the main body 1. For this reason, case 2 is
Unnecessary rotation in the direction away from the position 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. Along with this, the disk 31 of the crushing body 30 fixed to the rotating shaft 10 rotates. The blade body 32 rotates together with the disc 31, and the long blades 32a and short blades 32b crush the ice blocks inside the charging tube 3 into ice pieces. The ice pieces are discharged from the gap between the lower end of the charging tube 3 and the upper surface of the disk 31 as the disk 31 rotates. The size of the ice pieces 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 ejected ice pieces are sent out from between the lower surface of the disk 31 and the lower end of the inner cylinder 20 of the case 2 to the ice piece removal passage 5 by the wings 40 on the lower surface of the disk 31, and are also directly sent to the ice piece removal passage 5. Sent out.

When the lid 4 is pressed by hand in order to operate the switch 11, the flange 3a of the charging cylinder 3 is held between the lower end of the lid 4 and the rib 24 of the case 2, and the charging cylinder 3 is moved vertically. Since it is clamped and fixed so that it does not 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 pieces can be kept constant.

The obtained ice pieces pass through the ice piece removal passage 5 and hit the inner surface of the ice piece outlet body 6, change direction, attenuate the speed, and are discharged from the lower end opening. As shown in FIG. 16, an ice piece tray 53 is placed below the lower end opening of the ice piece outlet body 6 to receive the ice pieces that are discharged.

As ice chips continue to be formed, the ice chips adhere to the inner surface of the ice chip outlet body 6 and grow. Therefore,
The scraper 51 is rotated by the knob 52 to remove ice chips adhering to the inner surface of the ice chip outlet body 6.

In this embodiment, the following effects can be obtained.

First, with the lid 4 covering the charging tube 3 provided on the case 2, the user presses the lid 4 with his/her hand to lower the switch actuating rod 26, and the switch actuating rod 26 closes the switch 11 provided on the main body 1. By turning on the main body 1
The crushing body 3 provided in the case 2 is driven by the electric motor 7 provided in the case 2.
Rotate 0. Therefore, since the electric motor 7 of the main body 1 is driven only when the lid 4 placed on the case 2 is pressed, the electric motor 7 on the main body 1 side is not driven with the lid 4 removed on the case 2 side. Therefore, the electric motor 7 on the main body 1 side may operate while the lid 4 is removed on the case 2 side, causing accidents such as ice cubes and pieces of ice inside the case 2 to fly out or injuring the user's hands. can be prevented from occurring.

[0048] Furthermore, when the charging tube 3 is placed in the case 2,
It is placed on a rib 24 provided on the case 2. When the lid 4 placed on the case 2 is pressed and the switch 11 on the main body 1 side is turned on, the lid 4 presses the flange 3a of the charging tube 3 placed on the rib 24 from above. As a result, the flange 3a of the charging cylinder 3 is clamped and fixed. For this reason, the charging tube 3 is fixed to prevent the electric motor 7 from floating when the electric motor 7 is driven.
When driving, the size of the gap between the lower end opening of the charging tube 3 and the crushing body 30 can be kept constant, so that the size of the ice pieces can be kept constant.

Furthermore, when the user presses the lid to turn on the switch, the lid 4 fixes the charging tube 3 at the same time, so a special lid fixing part is provided in the case to fix the lid 4 to the case 2. There's no need.

Furthermore, since the upper end of the switch actuating rod 26 is formed with an inclined portion 26a that slopes toward the side edge, it is possible to prevent the lid 4 from pinching an ice block and pushing down the switch actuating rod 26. can. That is, lid 4
When placed over the case 2, it presses the flange 3a of the charging cylinder 3 placed on the rib 24 of the case 2 from above and is placed on the upper end of the switch operating rod 26. Then, push the lid 4 downward until the switch operating rod 26 descends with the stroke necessary to operate the switch 11.
When pressed down, the lid 4 sufficiently presses the flange 3a of the charging cylinder 3 placed on the rib 24 of the case 2. but,
If an ice block is placed on the upper end of the switch operating rod 26 and the lid 4 pinches the ice block and pushes down the switch operating rod 26, the lid 4 will simply push downward a short distance equal to the thickness of the ice block. The switch operating rod 26 is lowered with a stroke necessary to operate the switch 11. In other words, the switch 11 is turned on and the electric motor is rotated before the lid 4 fully secures the charging cylinder 3. For this reason, the charging cylinder 3 may float up during the crushing of the ice cubes, and ice pieces of a certain size may not be obtained as described above. However, if the sloped part 26a is formed at the upper end of the switch actuating rod 26, even if an ice block is placed on the upper end of the switch actuating rod 26, it will fall along the slope part 26a, so the lid 4 will pinch the ice block and switch the switch. By avoiding the situation where the actuating rod 26 is pushed down, the above-mentioned problem can be prevented.

It should be noted that the present invention is not limited to the embodiments described above, and can be implemented with various modifications.

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

[0053] The form of the switch actuating member is not limited to that of the embodiment.

The position where the upper end of the switch actuating member and the lid come into contact is not limited to above the upper surface of the portion of the case where the charging cylinder is supported by the charging cylinder receiving portion, but may be below.

The form of the sloped portion at the upper end of the switch actuating member is also not limited to the embodiment.

[0056] The main body in which the electric motor and the switch are provided may be exclusively combined with the case as in the embodiment, or it may be integrated with the case, or the main body of a cooker such as a mixer may be used. .

[Effects of the Invention] As explained above, according to the ice crusher of the present invention, the user manually presses the lid placed on the case to lower the switch operating rod and turn on the switch provided on the main body. Since the electric motor installed on the main body is driven, the electric motor on the main body does not operate when the cover is removed from the case, and the electric motor on the main body does not operate when the cover is removed from the case. It is possible to prevent accidents such as ice cubes or pieces of ice inside the case from flying out and injury to the user's hands.

Furthermore, when the lid placed on the case is pressed to turn on the switch on the main body side, the lid presses the portion of the charging cylinder placed on the charging cylinder receiving portion of the case from above and fixes the charging cylinder. The size of the ice pieces obtained by crushing the ice cubes is prevented by preventing the loading tube from floating up when the electric motor is driven, and by keeping the size of the gap between the lower end opening of the loading tube and the crushing body constant when the electric motor is running. can be maintained at a constant level.

Furthermore, when the user presses the lid to turn on the switch, the lid fixes the charging tube at the same time, so when the electric motor is driven, the lid is pressed by hand to fix the loading tube, so the lid is fixed to the case. There is no need to provide a special lid fixing part on the case for this purpose, and it is possible to eliminate the complexity of the structure of the case and the increase in manufacturing costs.

Furthermore, since the upper end of the switch actuating member is formed with an inclined part that slopes toward the side edge, even if an ice block is placed on the upper end of the switch actuating member, it will fall along the inclined part, and the lid will be damaged. In order to avoid the situation where the operator presses down the switch actuating member while holding the ice block, turning on the switch and rotating the motor before the lid has sufficiently fixed the charging tube, the charging tube may float up while the ice block is being crushed and the above-mentioned It is possible to prevent the occurrence of a situation where ice pieces of a certain size cannot be obtained as described above.
