Description

Circulation type mixing device {Rotation type mixing device}

The present invention relates to a blender for pulverizing food, and in particular, to a circulating blender having excellent grinding effects by circulating food in a container.

In general, a blender is a device that finely crushes various foods such as fruits and vegetables by rotating a blade by the rotational force of a driving motor.

Such a blender crushes food finely and then discharges it to the outside through a discharge pipe.In a conventional blender, food that is not properly crushed due to the juice generated in the process of crushing the food does not contact the blade and floats, resulting in crushing efficiency. As a result, the food lumps that are not finely crushed are discharged through the discharge pipe, thereby reducing the drinking effect of the user and reducing product reliability.

In addition, in order to prevent incomplete grinding as described above, the discharged food is put into the blender again and restarted, or the blender is stopped during the grinding operation, and then a mixing rod is inserted into the blender container to mix the food. , There was an inconvenient and cumbersome problem to use.

In addition, there is a problem in that the discharge valve of the blender is often blocked due to incomplete pulverization, so that the user must perform maintenance at a high cost.

In addition, the rotating cylinder 410 has an outer diameter that is relatively smaller than the inner diameter of the container 200, and thus, the side of the rotating cylinder 410 is spaced apart from the inner peripheral surface of the corresponding container 200 at a predetermined interval, and rotates accordingly. A certain circular space is provided between the side surface of the cylinder 410 and the inner peripheral surface of the container 200.

Here, the space outside the side of the rotary cylinder 410, that is, the space between the side of the rotary cylinder 410 and the inner circumferential surface of the container 200 is a space in which food is refluxed for circulation as described later, and this is a reflux space (RS , rotating space), and correspondingly, a space inside and above the rotating cylinder 410, that is, a space in which food is crushed by the crushing unit, is defined as a crushing space (CS).

The rotating cylinder 410 discharges food pulverized to a predetermined size by the pulverization unit in the pulverization space CS to the reflux space RS, and is rotated by the driving motor 110, The rotational force is applied so that the food is refluxed.

Here, the rotating cylinder 410 is installed close to the inner bottom surface of the container 200, and is rotated by the driving motor 110, and the rotating cylinder 410 interferes with the inner bottom surface of the container 200 It is installed in close proximity so that a minute gap of about 1 to 2 mm exists between the lower end and the bottom surface of the container 200 so as not to occur.

As illustrated in FIG. 3, the rotating cylinder 410 includes a frame portion 411 having an open top, bottom, and side surfaces while having a cylindrical shape.

In addition, a cross (+)-shaped support 412 is formed at the open lower end of the frame part 411.

The central portion of the support 412 is coupled to the motor shaft of the driving motor 110, and thus the frame part 411 is rotated according to the operation of the driving motor 110.

Here, the support 412 may have a blade portion 412a formed along the side to have a pulverizing function of food when rotating.

In addition, a filtering net part 413 through which food of a certain size can pass is provided on the open side of the frame part 411, and accordingly, the food pulverized in the pulverizing space CS is disposed in the filter net part 413. It passes through and is discharged to the outside of the reflux space RS.

In addition, a plurality of wing protrusions 414 may be arranged at regular intervals on a side surface of the frame part 411.

The plurality of wing protrusions 414 protrude from the side of the frame part 411 so that when the frame part 411 is rotated, the food in the reflux space RS is pressed and moved so that the food is refluxed along the reflux space RS. do.

The spatial partition 420 separates the reflux space (R.S) and the grinding space (C.S).

The spatial partition 420 is formed to protrude from the inner circumferential surface of the container 200 on the upper side of the rotary cylinder 410, and may protrude to a position corresponding to the upper end of the rotary cylinder 410.

Here, a minute gap in mm unit between the inner end of the spatial partition 420 and the upper end of the rotating cylinder 410 so that the spatial partition 420 protruding from the container 200 and the rotating rotating cylinder 410 do not interfere with each other. Exists.

In addition, the spatial partition 420 may be formed to be inclined downward at a certain angle so that food pulverized by the pulverizing unit is not disturbed by the spatial partition 420 and easily enters the interior of the lower rotating cylinder 410.

The circulation pipe 430 is formed to extend upward by a predetermined length through the spatial partition 420.

This circulation pipe 430 guides the food in the reflux space R.S to the grinding space C.S.

The perfusion guide piece 440 is formed in the reflux space RS, as illustrated in FIG. 4, and induces the food F refluxing along the reflux space RS to flow into the circulation pipe 430 do.

That is, the perfusion guide piece 440 is formed to block the path of food moving in the lower position of the circulation pipe 430 that has passed through the spatial partition 420, and accordingly, as illustrated in FIG. Food (F) refluxing along the reflux space (RS) by the rotation of the tubular body (410) is blocked by the perfusion guide piece (440) and the direction of travel changes, so that it is introduced into the upper circulation pipe (430). .

Here, the perfusion guide piece 440 may be formed to be inclined at a certain angle in the direction of the reflux of the food as illustrated in FIG. 5 so that the refluxed food F flows into the circulation pipe 430 more smoothly.

The blender of the present invention described above may further include a discharge unit for discharging the pulverized food to the outside of the container 200.

The discharge unit may include a discharge pipe 510, a discharge valve 520, and a discharge guide piece 530.

The discharge pipe 510 is formed at a lower side of the container 200 to discharge the pulverized food to the outside of the container 200.

The discharge valve 520 is installed in the discharge pipe 510 to open and close the discharge pipe 510 according to a user's manipulation.

As illustrated in FIG. 4, the discharge guide piece 530 is formed in the reflux space R.S to induce food F to flow into the discharge pipe 510.

That is, the discharge guide piece 530 is formed in the reflux space RS corresponding to the position of the discharge pipe 510, and similar to the flow guide piece 440, blocks the path of the moving food F. Induces food to easily flow into the discharge pipe 510.

Here, the discharge guide piece 530 of the discharge part and the perfusion guide piece 440 of the above-described circulation part guide the refluxed food (F) to smoothly flow into the discharge pipe 510 or the circulation pipe 430, respectively, All are formed on the reflux space RS.

Therefore, as illustrated in FIG. 4, the discharge guide piece 530 and the perfusion guide piece 440 are preferably formed on opposite sides of each other, and in the end, when the circulation pipe 430 is formed on the inner side of the container 200, the discharge pipe (510) is preferably formed in the opposite direction of the circulation pipe 430, that is, the other side of the container 200.

On the other hand, the perfusion guide piece 440 and the discharge guide piece 530 all have a spaced apart so as not to interfere with the rotating rotary cylinder 410 and the wing protrusion 414 protruding from the rotary cylinder 410, thus Although the path of food F refluxed by the perfusion guide piece 440 and the discharge guide piece 530 is not completely blocked, it may be difficult to achieve smooth reflux.

That is, in the process of pulverizing food, the food should be guided by the perfusion guide piece 440 while refluxing along the reflux space RS while the discharge valve 520 is closed and introduced into the circulation pipe 430. In, since the reflux flow of food is obstructed by the discharge guide piece 530, smooth reflux and inflow of the circulation pipe 430 may not be efficient, and the same problem may occur in the discharge process after completion of pulverization.

Therefore, according to an embodiment, the perfusion guide piece 440 and the discharge guide piece 530 may be configured to selectively block the path of food F in the reflux space RS according to the grinding process or the discharge process. have.

To this end, as illustrated in FIGS. 6 and 7, the perfusion guide piece 440 and the discharge guide piece 530 are each configured to be rotatable, and the circulation part is a circulation motor that rotates the perfusion guide piece 440 In addition to further including 450, the discharge unit may be configured to further include a discharge motor 540 for rotating the discharge guide piece 530.

Here, the circulation motor 450 and the discharge motor 540 may be step motors with easy angle adjustment.

In addition, it may include a motor control unit 600 for controlling the circulation motor 450 and the discharge motor 540 to operate opposite to each other according to the opening and closing operation of the discharge valve 520.

That is, when the discharge valve 520 is closed, the motor control unit 600 controls the discharge motor 540 so that the discharge guide piece 530 rotates horizontally so as not to interfere with the flow of food (F). , The perfusion guide piece 440 is rotated to be erected at a certain angle to control the circulation motor 450 to guide the food F to the circulation pipe 430.

Conversely, when the discharge valve 520 is opened, the flow guide piece 440 rotates horizontally to control the circulation motor 450 so as not to interfere with the flow of the food F, and the discharge guide piece 530 is vertically It is rotated to be erected to control the discharge motor 540 to guide the food (F) to the discharge pipe 510.

Therefore, in the pulverization process in which the discharge valve 520 is closed, only the through-flow guide piece 440 obstructs the path of the food, so that the food F can flow into the circulation pipe 430 smoothly, and the discharge valve In the discharging process in which the 520 is opened, only the discharging guide piece 530 obstructs the path of the food, so that the food F can be smoothly introduced into the discharging pipe 510.

A brief look at the operation of the blender according to the present invention made of the above-described configuration is as follows.

First, the driving motor 110 is operated by operating the operation unit 120 provided in the main body 100 in a state in which food to be crushed such as fruit is put into the container 200 and accommodated.

Then, as the crushing rotation shaft 310 is rotated according to the operation of the driving motor 110, food is sequentially pulverized by a plurality of crushing blades 320 arranged vertically, and the crushed food is at the bottom of the container 200 It is collected in the rotating cylinder 410 of.

And, since the rotating cylinder 410 is also rotated according to the operation of the driving motor 110, the food collected into the rotating cylinder 410 is rotated together, and the filtering net on the side of the rotating cylinder 410 by centrifugal force ( It is discharged to the reflux space RS through 413).

At this time, since the bottom of the rotating cylinder 410 is open and a crushing guide groove 210 is formed on the bottom of the container 200, the food inside the rotating cylinder 410 is at the bottom of the rotating cylinder 410. As the support 412 and the container 200 continuously collide with the crushing guide groove 210 on the bottom surface, additional crushing is performed.

On the other hand, food discharged into the reflux space RS is refluxed while moving along the reflux space RS by receiving friction with the rotating rotating cylinder 410 and pressurized by the wing protrusion 414 on the side of the rotating cylinder 410. Will come true.

And, when the food to reflux (F) reaches the position of the circulation pipe 430, it is introduced into the circulation pipe 430 according to the induction of the perfusion guide piece 440, and then guides upward along the circulation pipe 430. And re-supplied to the crushing part in the crushing space CS.

Accordingly, the food is further pulverized while passing through the pulverization unit again, and the pulverization of the food can be effectively performed by being pulverized repeatedly through such a circulation process.

Then, when the pulverization is completed through the above process, the discharge valve 520 is opened. Then, when the food (F) refluxing along the reflux space (RS) reaches the position of the discharge pipe (510), it flows into the discharge pipe (510) according to the induction of the discharge guide piece (530) to smoothly outside the container (200). Therefore, the user can conveniently drink the discharged food by putting it in a cup or the like.

As described above, it can be seen that the circulating blender of the present invention has an excellent pulverizing effect because food is circulated in the container and pulverized repeatedly by the pulverizing unit.

In addition, food remaining inside the rotating cylinder may be difficult to crush due to lack of moisture. It is repeatedly pulverized through circulation, and a crushing guide groove is formed on the bottom of the container as the bottom of the rotating cylinder is opened. Since it is configured to continuously pulverize food, it can be seen that various foods can be effectively pulverized irrespective of the amount of moisture or the type of food.
