Description

Vacuum Mixer {VACCUM BLENDER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum mixer, and more particularly, to a vacuum mixer capable of mixing food and beverages such as fruits and vegetables in a vacuum state.

The blender is one of the most used electric appliances in the household today, and it can grind fruits such as fruits, vegetables and grains finely using mixer blades that are rotatably installed under the storage container.

In general, the blender is rotated in a high speed rotating motor by closing the lid after inserting the food to be crushed into the storage container. In this process, the air in the storage container and the crushed food granules are mixed at a high speed and many bubbles are generated . For example, when a fruit such as a banana or a tomato is put in a blender and crushed, a large amount of air bubbles are generated in the upper part of the fruit juice. This not only lowers the taste and texture of fruit juices, but also means that the fruit fibers have already been oxidized during the grinding process and the nutrients have been largely destroyed.

In addition, when foods are stored without being consumed immediately after they are crushed, if they are stored in an air-exposed state, the oxidation process progresses more rapidly, the destruction of fibers and nutrients accelerates, the color is discolored, And layer separation occurs between food and food. The foodstuffs crushed by the blender were difficult to store for a long period of time unless they were eaten immediately.

To solve these problems, a vacuum mixer designed to grind foods in a vacuum state has been developed. One example is disclosed in Japanese Laid-Open Patent Application No. 2013-111079 entitled "High-Speed Vacuum Agitation Method of Inorganic Poppy Fruit Juice / Food and Mixer" (Document 1). In this vacuum mixer, the storage container is covered with a sealing lid, and air is taken out through a vacuum throat provided in the sealing lid. At this time, the switching valve is operated so that the vacuum throat of the sealing lid and the vacuum pump are connected. When the vacuum state is below 300 mbar, the motor of the mixer operates to stir the food. When the stirring process is completed, the operation of the vacuum pump is stopped. At the same time, the suction valve is opened and the vacuum state is released so that the sealing lid can be easily separated It does.

However, since this vacuum mixer was required to use a vacuum device in which various components such as a vacuum pump, a switching valve, an intake valve, a vacuum pump, and a pressure gauge were connected to the outside of a general blender, the operation was very inconvenient There is an inconvenience in that it must be separated from the blender and stored separately.

Further, the vacuum mixer has a problem that since the vacuum pump is stopped and the intake valve starts to open and air enters into the storage container, the crushed food can not be stored in a vacuum state for a long time in the storage container.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as adhering to the prior art already known to those skilled in the art.

FIG. 10 is a view showing a state in which the auxiliary container is engaged, and FIG. 11 is a partial sectional view showing an operating state of the vacuum depressurizing portion.

The vacuum mixer 100 according to the present invention includes a machine operation part 200 in which a machine part for vacuum and crushing is built in, a storage container 510 extending to a certain height from the machine operation part 200, A vacuum decompression unit 400 extending horizontally from the supporter 300 and provided with a vacuum decompression mechanism for providing a space that can be seated on the machine unit 200, And a vacuum crushing unit 500 installed between the vacuum decompression unit 400 and the crushing unit 500 to crush food stored in a vacuum state.

The machine operation unit 200 includes a main body 210 having an internal space and a vacuum pump 230 and a rotation motor 240 installed in the internal space of the main body 210.

The main body 210 is provided with a series of operation buttons 220 which are operated by the user and perform various functions, such that the operation buttons 220 are exposed to the outside of the main body 210. In addition, a seating surface is provided at the upper end of the main body 210 so that the storage container 510 can be placed in interlock with the mechanical operation part 200.

Since the vacuum pump 230 is connected to the support part 300 and the vacuum tube 320 extending to the vacuum decompression part 400, the vacuum pump 230 is preferably installed adjacent to the support part 300, Is preferably installed adjacently to the storage container 510 in order to be interlocked with the mixer blade 515 installed in the storage container 510. The connection structure between the rotation motor 240 and the mixer blade 515 of the storage container 510 will be described later with reference to FIG.

An intake nozzle 231 is provided on one side of the vacuum pump 230 and a vacuum tube 320 is extended to the vacuum depressurization part 400 through the inside of the support part 300 Respectively. To this end, the support part 300 has a space for accommodating at least the vacuum tube 320 therein.

A pressure sensor 330 may be installed on the vacuum tube 320 to check the vacuum state of the vacuum tube 320. On the other hand, since the vacuum tube 320 is usually made of a soft plastic material, the pressure sensor 330 may not be suitable for installation. In this case, as shown in FIG. 2, the vacuum tube 320 is cut, and a rigid connection tube 340 is connected therebetween. Then, a pressure sensor 330 is mounted on the connection tube 340 It can also be installed.

The support portion 300 is constructed to have a substantially constant height. As a result, the space for accommodating the storage container 510 is provided between the vacuum decompression unit 400 connected to the upper portion of the support unit 300 and the seating surface of the machine operation unit 200, Same as.

The supporting part 300 may be coupled to the upper end of the supporting part 300 by a hinge 310 so that the vacuum decompression part 400 can be rotated. As a result, since the vacuum decompression unit 400 can move up and down with the upper end of the support unit 300 as the center of rotation, the storage container 510 can be moved to the machine operation unit (not shown) without being disturbed by the vacuum decompression unit 400 200). ≪ / RTI >

According to another embodiment of the present invention, as shown in FIG. 9, the support part 300 may be vertically adjustable in length by the vertical connecting part 350. When the storage container 510 is mounted on the machine operation unit 200, the vertical connection unit 350 is lifted up, so that the storage container 510 is seated without being disturbed by the vacuum decompression unit 400 .

In addition, according to the present embodiment, the height of the vacuum depressurization unit 400 can be freely adjusted by moving the vertical connection unit 350 up and down. As a result, it is possible to use a storage container 510 having a different capacity in one vacuum mixer 100.

Meanwhile, the length of the body 410 may be adjustably adjusted by the horizontal connecting unit 411 in the vacuum depressurization unit 400. Therefore, even when a separate auxiliary vessel is used as well as the storage vessel 510, it is possible to place the auxiliary vessel in the machine operation unit 200 for reducing the pressure of the auxiliary vessel regardless of the size of the auxiliary vessel, Do.

2 to 4, the vacuum decompression unit 400 includes a body 410 connected horizontally from the upper portion of the support unit 300, A first vacuum chamber 450 communicating with the connection nozzle 440 through the connection hole 320 is formed. The upper and lower portions of the first vacuum chamber 450 communicate with the outside of the body 410 and the upper portion of the first vacuum chamber 450 is selectively opened and closed by the first vacuum stopper 430 .

Therefore, the vacuum state of the first vacuum chamber 450 can be easily released by the user by lifting the first vacuum stopper 430. At this time, a handle 431 may be attached to the upper portion of the first vacuum stopper 430 to allow the user to hold the handle and manually open and close the handle.

The vacuum decompression part 400 is provided with a receiving groove 420 in which the first vacuum stopper 430 is mounted and a mounting hole 420 in which the first vacuum stopper 430 is inserted, And one or more suction holes 412 selectively opened and closed by the first vacuum stopper 430 may be formed around the mounting hole 411. [ By inserting and fixing the first vacuum stopper 430 on the mounting hole 411 and then lifting a part of the first vacuum stopper 430 without completely detaching it from the body 410, the intake hole 412 can communicate with the outside have. As a result, it is possible to easily release the vacuum without removing the first vacuum stopper 430 completely.

The vacuum decompression unit 400 may be mounted with a decompression unit packing 470 so that the vacuum decompression unit 400 may be in close contact with the sealing lid 530 at a lower portion communicated with the outside of the body 410. The depressurizing portion packing 470 functions to maintain the vacuum state of the vacuum depressurization portion 400 and the vacuum crushing portion 500 during the vacuum depressurization process and the vacuum crushing process.

When the vibration pump 230 is operated in the vacuum depressurization process of the vacuum mixer according to the embodiment of the present invention, considerable vibration occurs. When the adhesion of the packing 470 holding the vacuum by the vibration is weakened, the vacuum is not smoothly formed in the first vacuum chamber 450. As a result, the first vacuum chamber 450, the second vacuum chamber 580 ), The vacuum decompression process may not proceed properly. The vibration generated in the vacuum pump 230 is propagated to the entire blender as the vacuum pump operates. Since the vacuum decompression unit 400 is hinged to the support unit 300, the vibration generated in the vacuum pump 230 Is expanded while being propagated through the main body 210 of the machine operation part, the support part 300 and the hinge 310, so that the vacuum decompression part 400 located at the upper part is larger than the vibration which is received by the lower part of the mixer body . When the vacuum decompression unit 400 and the first vacuum chamber 450 are strongly coupled to each other due to the difference in vibration, the vibration generated by the vacuum pump and transmitted through the hinge to the first vacuum chamber 450, The vibration transmitted to the sealing lid 530 of the part 500 is changed. As a result, different vibrations are simultaneously applied to the decompression part packing 470 sealing between the first vacuum chamber 450 and the sealing lid 530, so that the packing is weakened, The vacuum state can be released.

Referring to FIG. 5, it is preferable that the first vacuum chamber 450 is coupled to the body 410 of the vacuum depressurization unit 400 with a constant clearance 461 when engaged. For example, a through hole is formed in a latching rod 464 formed on a side surface of the first vacuum chamber 450, and a protrusion 462 formed downward in the body 410 of the vacuum depressurization portion 400 is inserted into the through- , And the engaging screw 463 is inserted and fixed upward in the projecting portion 464.

At this time, since the diameter of the head portion of the engaging screw 464 is configured to be larger than the diameter of the through hole of the engaging rod 464, the protruding portion 462 of the vacuum decompression portion 400 is not separated from the engaging rod 464 . However, since the head portion of the engaging screw 464 is configured not to completely come into close contact with the engaging rod 464, a clearance 461 of a certain size t is generated therebetween.

When the first vacuum chamber 450 and the body 410 of the vacuum decompression unit 400 are coupled with the clearance 461, the first vacuum chamber 450 is not tightly coupled to the vacuum decompression unit 400, And is tightly coupled only to the sealing lid 530 via the pressure-reducing part packing 470. [ As a result, it is not affected by the vibration applied from the upper vacuum depressurization portion 400, but is affected only by the vibration applied from the lower sealing lid 530. That is, since the first vacuum chamber 450 and the sealing lid 530 are shaken by the same vibration, there is no influence on the close contact surface of the decompression part packing 470 provided therebetween, so that even during the vacuum decompression process, It is possible to prevent the vacuum from being released.

The vacuum crushing unit 500 is mounted on the machine operating unit 200 and has a second vacuum chamber 580 formed therein and a mixer blade 515 connected to the rotation motor 240 is installed in a storage container And a second vacuum stopper 540 is selectively opened and closed at a portion of the vacuum depressurizing portion 400 which is sealably connected to the lower portion of the first vacuum chamber 450. [ And a cover 530.

The storage container 510 is provided with a handle 520 on one side for the convenience of the user. A second vacuum chamber 580 formed in the interior of the storage container 510 provides a storage space for containing food to be crushed.

The vacuum state of the second vacuum chamber 580 can be easily released by the user by lifting the second vacuum stopper 540. 6, a handle 541 may be attached to the upper portion of the second vacuum stopper 540 so that the user can manually open and close the second vacuum stopper 540 by hand.

The sealing lid 530 is provided at its central portion with a receiving groove 550 for receiving a second vacuum stop 540 and a mounting hole 550 for receiving a second vacuum stop 540 And one or more intake holes 552 selectively opened and closed by the second vacuum stopper 540 may be formed around the mounting hole 551. The second vacuum stopper 540 is inserted and fixed on the mounting hole 551 and then the suction hole 552 is communicated with the outside by slightly lifting a part of the second stopper 540 without completely detaching it from the sealing lid 530 . As a result, it is possible to easily release the vacuum without having to separately insert the second vacuum stopper 540.

Since the vacuum mixer according to the present invention must maintain a vacuum state during grinding of the food in the storage container 510, the packing structure for sealing is very important. In the present invention, a double packing structure is employed instead of the single packing structure employed in a general blender, so that the space between the storage container 510 and the sealing lid 530 can be completely sealed, which will be described in detail with reference to FIG.

First, a step 511 is formed inside the upper part of the storage container 510 and a first lid packing 560 is attached to the lower part of the sealing lid 530 so as to be in close contact with the horizontal surface of the step 511 do. In the vacuum state, the sealing lid 530 is subjected to a force pulled toward the second vacuum chamber 580 due to a difference in pressure. Accordingly, when the packing of the sealing lid 530 is laterally contacted with the upper and lower vertical surfaces of the storage container 510, the packing can be relatively easily separated by the pulling force toward the second vacuum chamber 580. [

In the present invention, the step 511 is formed in the storage container 510, and the first lid packing 560 is mounted so as to be in close contact with the horizontal surface of the step 511 and below. As a result, even if a force is applied to attract the second vacuum chamber 580 in the vacuum state, the horizontal surface of the step 511 firmly supports the first lid packing 560, so that the sealing effect can be maintained.

A second lid packing 570 is disposed at a lower portion of the sealing lid 530 and above the first lid packing 560 so that the second lid packing 570 can be closely contacted to the upper and lower inner surfaces of the storage container 510 Respectively. Since the second lid packing 570 is a packing structure adopted in a general mixer, detailed description is omitted.

The first lid packing 560 and the second lid packing 570 are mounted between the first mounting protrusion 533, the second mounting protrusion 532 and the third mounting protrusion 531, Not only detached but also is firmly mounted without being detached from the sealing lid 530.

8 shows the connection structure of the vacuum crushing unit 500 and the machine operation unit 200 according to the present invention in detail. When the storage container 510 of the vacuum crushing unit 500 is placed on the seating surface of the machine operation unit 200, the rotation shaft of the rotation motor 240 mounted in the main body 210 of the machine operation unit 200 The rotation plate 512 installed on the bottom surface of the storage container 510 is fitted to the rotation base 250 connected via the connection ring 260. A filament shaft 514 is coupled to the rotating plate 512 via a bushing 513 and a mixer blade 515 is disposed on the upper end of the rotating shaft 514 so as to be positioned at an inner lower end of the storage container 510 Respectively.

A bearing 516 for smooth rotation and a lower packing 517 for sealing the storage container 510 are mounted around the rotating shaft 514. The lower packing 517 is preferably provided in a double packing structure to maintain the vacuum state of the storage container 510. According to another embodiment of the present invention, the lower packing 517 may be installed as a bi-directional packing in order to enhance the hermeticity.

10 is a view showing a state in which the auxiliary vessel is coupled to a vacuum mixer according to an embodiment of the present invention. In the present invention, when a material is pulverized by using a vacuum mixer, it is possible to use a separate storage container 600 so that it can be stored in a vacuum state. At this time, a vacuum in the auxiliary container 600 can be formed by using the vacuum pump 230 while using a vacuum mixer. Referring to FIG. 10, a vacuum distributor 350 may be installed between the vacuum pump 230 and the vacuum tube 320. The vacuum distributor 350 not only lowers the air pressure of the first vacuum chamber 450 and the second vacuum chamber 580 by the vacuum pump 230 but also reduces the air pressure of the first auxiliary vacuum tube 351 and the second auxiliary vacuum tube 580, So that a vacuum can be formed in the auxiliary container through the second valve 352.

The first auxiliary vacuum tube 351 may be connected to an auxiliary container 600 separately provided to the outside and the second auxiliary vacuum tube 352 may be connected to a vacuum pump 230 . Additionally, a third auxiliary vacuum tube 353 can be branched at the vacuum distributor 350, which can be connected to a separate pressure sensor to measure the pressure in the vacuum distributor.

Unlike the vacuum crushing unit 500, the auxiliary vessel 600 uses the first auxiliary vacuum tube 351 outside, so that the size and shape of the vessel are not limited. Various types of auxiliary containers 600 can be used, and the lid of the auxiliary container 600 can be configured in the same manner as the first vacuum stopper 430 in the present invention.

In addition, the vacuum distributor 350 may be provided in the form of a valve, and the vacuum tube 320 and the first auxiliary vacuum tube 351 may be opened or closed according to the operation state of the vacuum mixer, It is possible to selectively perform depressurization of the vacuum crushing section 500 and decompression of the auxiliary container 600 by opening the tube where it is desired.

The vacuum decompression process and the decompression process of the vacuum mixer according to the present invention will be briefly described with reference to FIG.

11 (a) shows the flow of air at the connection portion between the vacuum decompression unit 400 and the vacuum crushing unit 500 during the vacuum decompression process. When the vacuum pump 230 is operated while the first vacuum chamber 450 of the vacuum decompression unit 400 is sealed by the first vacuum stopper 430, air is sucked through the vacuum tube 320, The vacuum cap 430 is subjected to a downward force. At this time, since the first vacuum stopper 430 is further attached to the body 410 of the vacuum depressurization portion 400 in the downward direction, the first vacuum stopper 430 is maintained in a closed state. Therefore, air can not flow from the outside of the body 410 of the vacuum depressurization portion 400.

On the other hand, when the vacuum pump 230 is operated in a state where the sealing lid 530 of the vacuum crushing unit 500 is sealed by the second vacuum stopper 540, the second vacuum stopper 540 is moved to the first vacuum chamber 540, The air is lifted up in the direction of the arrow 450 so that the air is circulated. As a result, the air in the second vacuum chamber 580 formed inside the storage container 510 is discharged to the vacuum pump 230 through the first vacuum chamber 450. The first vacuum chamber 450 of the vacuum decompression unit 400 and the second vacuum chamber 580 of the vacuum crushing unit 500 are maintained in the same vacuum state do.

11 (b) shows a vacuum release process using the first vacuum stopper 430. FIG. In the vacuum state formed through the process of FIG. 11A, the vacuum crushing unit 500 rotates the mixer blade 515 to crush foodstuffs. After the grinding process is completed, it is necessary to release the vacuum state in order to separate the storage container 510 from the vacuum mixer 100. At this time, according to the present invention, the user can easily release the vacuum state by slightly raising the first vacuum stopper 430 of the vacuum depressurization portion 400. That is, since the vacuum is released through the first vacuum stopper 430, the vacuum in the first vacuum chamber 450 is released.

On the other hand, the second vacuum stopper 540 is subjected to a force pulled toward the second vacuum chamber 580 in a vacuum state. And the second vacuum stopper 540 is further tightly attached to the body of the sealing lid 530 in the downward direction, so that the sealed state is maintained. This is clearly distinguished from the fact that the vacuum state in the storage container is released simultaneously with the pulverization of the food in the conventional vacuum mixer described in Document 1. Therefore, by using the vacuum mixer of the present invention, even if the pulverized food is not eaten immediately, it can be stored in a vacuum state for a long time for a long time.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand.
