Description

  The present invention relates to a counter-rotating food chopper, and more particularly to a counter-rotating food chopper that can accelerate the speed of chopping food and can select the direction of rotation according to the needs of food chopped granules.

Household food chopper is applied to minced meat, minced meat and so on.
Conventional household food choppers use a motor to drive the rotation of the cutter unit and chop the food.

When the conventional motor drives the rotation of the cutter unit, there are two types of modes: one-way rotation and forward and reverse rotation.
In the one-way rotation mode, some food sticks to the container wall and cannot be minced uniformly, which tends to increase the mince time.

The forward / reverse bi-directional rotation mode includes “a minced meat / meat cut integrated machine power drive device” of Patent Document 1.
In Patent Document 1, a pulley is installed at the rear end of the main shaft.
An output shaft corresponding to the main shaft is installed behind the main shaft, and a first one-way clutch is mounted between the main shaft and the left end surface of the pulley.
A second one-way clutch is attached between the right end surface of the pulley and the output shaft.
The forward / reverse rotation of the pulley can selectively drive forward rotation of the output shaft or counter-rotation of the main shaft.
After adopting the above structure, the two one-way clutches always correspond to the pulleys, and due to the one-way rotation characteristics of the two one-way clutches, the pulley's forward / reverse rotation causes one of the one-way clutches to By selectively driving, the output shaft rotates forward or the main shaft rotates counterclockwise.
However, although the structure of Patent Document 1 can rotate in the forward and reverse directions, in addition to the arrangement of the pulley, the first and two-way clutches are installed, so there are many components and the cost is high.

Chinese Patent No. 20151521004086.1

  The prior art has the disadvantages that in addition to the arrangement of the pulley, the first and second one-way clutches are installed, so there are many components and the cost is high.

  The present invention relates to a counter-rotating food chopper that can accelerate the food chopping speed and can select the direction of rotation according to the needs of food chopped granules.

A forward / reverse rotating hood chopper according to the present invention includes a forward / reverse rotating motor, two forward / reverse rotating switches, and a cutter unit having a bidirectional cutter blade.
The forward / reverse rotation switch controls the forward / reverse rotation motor to drive the forward rotation or counter rotation of the cutter unit.
The chopping speed can be accelerated through the alternating rotation of the cutter unit, which is forward rotation or counter rotation.
Through different designs of the cutter unit's forward and reverse cutter blades, the direction of rotation of the cutter unit can be selected and food can be chopped using a suitable cutter blade as required for the food chopped granules.

As apparent from the above description, the present invention has at least the following advantages and effects in application.
1. The structure is simple, the cutter unit 20 is operated forward and reverse, and the forward rotation switch 42 and the anti-rotation switch 43 are alternately operated repeatedly, so that the cutter unit 20 rotates counterclockwise after the forward rotation and continues to rotate. In addition to preventing food from sticking to the wall of the container 10 in one direction, the food can be quickly minced.
2. If the forward rotation of the cutter unit 20 is selected according to the necessity of the mince level for the user's food, the outer arc blade 221 faces the food, cuts straight against the food, and the food can be minced more finely. Alternatively, if the counter-rotation of the cutter unit 20 is selected, the inner arc blade 220 faces the food (foodstuff) and is cut by being hooked on the food (foodstuff), and the food is chopped in a granular form.

It is combination sectional drawing of embodiment of this invention. It is a three-dimensional view of a cutter unit according to an embodiment of the present invention. It is a bird's-eye view of some cutter units by an embodiment of the present invention. It is sectional drawing cut | disconnected by AA of FIG.

[Example]
As shown in FIGS. 1 to 3, the food chopper 1 according to the embodiment of the present invention includes a container 10, a cutter unit 20 positioned at the center of the container 10, a lid 30 that covers the container 10, and a drive positioned above the lid 30. It has a device 40.

The cutter unit 20 is composed of a central shaft 21 and at least one cutter 22 extending outward from the outer wall of the central shaft 21 as shown in FIGS.
The bottom end 210 of the central shaft 21 is pivoted by the inner bottom end of the container 10 (see FIG. 3), whereby the bottom end 210 is supported.
The top end 211 protrudes through the central hole 31 provided in the center of the lid 30, and the joint tooth 212 having a tooth surface on the outer peripheral wall is firmly contacted with the top end 211.
Cutter blades are provided on both sides of the cutter 22 to form a bidirectional cutter blade in the forward and reverse directions.
The cutter 22 has an arcuate design. The cutter blade on the inner arc side is the inner arc blade 220, and the outer arc blade 221 is located at the relative end of the inner arc blade 220 (that is, the outer arc side).
Thereby, when the cutter unit 20 is rotated forward, an effect of cutting the food straight through the outer arc blade 221 is generated, and when counterclockwise, an effect of hooking the food through the inner arc blade 220 is generated.

The driving device 40 (see FIG. 3) is located above the lid 30 and has a case 41 on the outside.
A push-type forward rotation switch 42 and an anti-rotation switch 43 are installed at the top end of the case 41 and have a forward / reverse rotation motor 44.
The forward / reverse rotation motor 44 is electrically connected to the power supply circuit via the forward rotation switch 42 or the counter rotation switch 43.
Thereby, the axial center 45 of the forward / reverse rotation motor 44 is controlled to perform forward rotation or reverse rotation.
The output end 450 of the shaft center 45 has a drive shaft 47 after being connected to the gear box 46, and extends out of the case 41.
A meshing tooth 48 having an inner concave shape and a tooth surface on the inner peripheral surface is fixedly connected to the shaft end of the drive shaft 47.
The meshing teeth 48 are meshed with the joint teeth 212 and are interlocked together.

A state after the above-described constituent members are combined in order is shown in FIGS.
At the time of application, it is performed as follows.
1. When food (foodstuff) is chopped quickly: food (meat or vegetables) is placed in the container 10, the lid 30 is closed, and the driving device 40 is mounted on the lid 30, and the meshing teeth 48 are aligned with the joint teeth 212 and chewed. Connect them together. Next, the forward rotation switch 42 and the anti-rotation switch 43 are alternately pressed (for example, after the forward rotation switch 42 is pressed for 3 seconds, the anti-rotation switch 43 is pressed for 3 seconds, etc.). Thus, the food is repeatedly cut straight and hooked, and the food does not stick to the container 10 wall in one direction, and the food (foodstuff) is quickly chopped.
2. Depending on the food needs, it is selected whether to press only the forward rotation switch 42 or only the anti-rotation switch 43.
When the cutter unit 20 rotates in the forward direction, the outer arc blade 221 faces the food, and the food is made fine by the effect of cutting the food straight. When the food is meat, it is suitable for cooking meat and making ingredients such as wontons. When the cutter unit 20 rotates counterclockwise, the inner arc blade 220 faces the food (foodstuff), and the inner arc blade 220 is chopped so as to be hooked and cut with respect to the food (foodstuff). Thus, the food is chopped into granules, and if it is meat, it is suitable for making a boiled dumpling.

  The above-described embodiments of the present invention do not limit the present invention. Therefore, the scope protected by the present invention is based on the scope of claims for utility model registration to be described later.
