The present invention relates to a multi-purpose mixer capable of vacuum packaging, and more particularly, by combining a mixer and a vacuum generator, so as to have both functions, by placing the vacuum generator inside the support, free use of the mixer and The present invention relates to a multipurpose mixer capable of vacuum packaging to enable storage.

Generally, a blender is a device for making juice by slicing fruits and vegetables finely and mixing them with milk and yogurt.These kinds of blenders are various, but generally, the main body of the blender with a built-in driving motor and fruits and vegetables are placed on the bottom part. Consists of a blender cup having a grinding blade for grinding fruits, vegetables, etc., vacuum packaging device is a device for vacuum packaging food products that are easily altered. Since the mixer and the vacuum packaging device are manufactured and sold as separate devices, there are inconveniences that consumers have to purchase.

As shown in Figures 1 and 2 to solve this inconvenience, a device incorporating a blender and a vacuum generator has been invented. The vacuum packaging multipurpose mixer disclosed in Korean Patent Laid-Open Publication No. 2003-0028105 includes a mixer main body (driving unit) 20, a vacuum generator 30, a vacuum suction device, and a cup 50 for a mixer. It is composed. When the blender cup is assembled to the blender main body 20 as shown in FIG. 2, fruit, vegetables, etc. are pulverized by the grinding blade to make juice, and as shown in FIG. 1, the vacuum generator 30 is a blender main body 20. In the case of assembling), the vacuum is formed inside the vacuum container by the vacuum generating device 30, whereby vacuum packing is performed.

Looking at the configuration of the conventional vacuum generating device shown in Figure 1 in more detail, the drive unit 20 is composed of a motor 22 and a lower coupling 24 for transmitting the power of the motor to the outside, the vacuum generator is the upper couple The ring 32, the bevel gears 33 and 34, the vacuum pump 39, etc. are comprised. When the rotational force of the motor 22 is transmitted to the lower coupling 24, the lower coupling 24 rotates the upper coupling 32, the upper coupling 32 of the bevel gear is located on the opposite side of the same axis The small diameter gear 34 is rotated. The small diameter gear 34 of the bevel gear rotates again the large diameter gear 33 of the bevel gear, and the large diameter gear moves the rod 35 of the piston pump eccentrically coupled to the side thereof, so that the piston 36 reciprocates. Have them exercise. When the piston reciprocates, the air inside the vacuum container connected to the tube 41 is sucked into the pump suction port 37, thereby enabling vacuum packing of the vacuum container.

Reference numeral 60 in FIG. 1 denotes a pressure switch, which will be described. A cylinder 66 including a piston 62 and a rod 64 and a return spring 63 is installed inside the vacuum generator 30. In addition, the switch 65 is installed in the driving unit 20 so that the rod 64 can be contacted when the rod 64 is lowered, and the switch 65 is normally closed. A connecting pipe 61 connected to the pump suction port 37 of the piston pump is installed at a portion of the cylinder 66 on the side in which the return spring 63 is embedded, and the opposite side of the cylinder 66 is opened to the atmosphere. When a vacuum is formed at the pump suction port 37 and reaches a predetermined vacuum pressure, the rod 64 is lowered due to the difference between the atmospheric pressure and the vacuum pressure applied to both sides of the inner piston 62 of the cylinder 66. After the rod 64 is lowered by a predetermined amount, the power of the driving motor 22 is cut off by touching the switch 65. When the vacuum in the pump suction port 37 is released, the rod 64 is returned to its original position by the return spring 63.

Reference numeral 70 in FIG. 1 denotes a vacuum switch unit, which is composed of a vacuum coupling protrusion 71, a coupling groove 73, and a limit switch 72. The vacuum coupling protrusion 71 is formed to protrude in a rectangular shape from the lower portion of the housing of the vacuum generator 30, and the coupling groove 73 is formed on the driving unit 20 to be fitted to the coupling protrusion 71. When the coupling protrusion 71 and the coupling groove 73 are coupled, the lower portion of the coupling protrusion 71 touches the limit switch 72 built in the driving unit 20 so that the limit switch 72 is closed to drive the motor. 22 can be rotated at a low speed.

The vacuum switch unit 70 operates only when the vacuum generator 30 is coupled to the upper portion of the mixer body 20, and the vacuum switch unit operates when the grinding blade is coupled to the mixer body 20. Instead, the mixer switch unit 80 operates as shown in FIG. 2. The mixer switch unit 80 is composed of a coupling protrusion 81 for the mixer, the coupling groove 83 and the limit switch 82. The mixer coupling protrusion 81 and the coupling groove 83 are formed in a different shape from the vacuum coupling protrusion 71 and the coupling groove 73, and the mixer coupling protrusion 81 must be the mixer coupling groove 83. Is coupled to the mixer limit switch 82, thereby preventing malfunction.

3 is a circuit diagram schematically showing the interrelationship between the pressure switch 65 formed in the main body 20, the vacuum limit switch 72 and the mixer limit switch 82. As shown in FIG. The pressure switch 65 and the vacuum limit switch 72 are connected in series, the pressure switch 65 is normally closed and the vacuum limit switch 72 is normally open. As a result, when the vacuum generator 30 and the main body 20 are coupled, the vacuum limit switch 70 is closed, and the driving motor 22 is connected to a high resistance Rh, so that the driving motor 22 rotates at low speed. Operate in mode. When the predetermined vacuum pressure required for vacuum packaging is reached, the pressure switch 65 is opened to cut off the power supply of the drive motor 22. In the low speed rotation mode, the mixer limit switch 82 is always open. The mixer limit switch 82 is closed when the mixer cup 50 and the main body 20 are coupled, and is normally open. When the limit switch 82 for the mixer is closed, the drive motor 22 is connected to the low resistance R1, so that the drive motor 22 operates in the high speed rotation mode. In the high speed rotation mode, the vacuum limit switch 72 is always open.

Conventional vacuum packaging multi-purpose mixer having the configuration as described above has the advantage that the drive unit 20 and the vacuum generator 30 of the mixer is detachably coupled, but there was a problem that it is not easy to store, broth There was a problem that the lamp is introduced into the vacuum generating apparatus may cause a failure.

In order to solve the above problems, an object of the present invention is to facilitate the storage of the mixer body and the vacuum generating device by allowing the vacuum generating device to be built into the supporting part serving as a holder.

In addition, it is an object to prevent the broth and the like to prevent failure by entering the vacuum generating device.

The present invention provides a main body of a mixer having a drive motor and a lower coupling rotated by the drive motor to achieve the above object; A vacuum generating apparatus including an upper coupling coupled to the lower coupling and a vacuum pump driven by the upper coupling, wherein the main body of the mixer is detachable; In the multi-purpose mixer capable of vacuum packaging, the vacuum generator is built in the support portion, the support portion is formed in a tapered structure that is wider in diameter toward the lower portion, the air in communication with the pump suction port of the vacuum pump It characterized in that it comprises a suction unit.

More preferably, the liquid receiving portion is located between the pump suction port of the vacuum pump and the air suction portion, characterized in that the drip groove is removable in the liquid receiving portion.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

4 shows the drive unit 20 of the mixer. Since the driving unit 20 is a part constituting the main body 20 of the mixer, the same reference numerals as those of the mixer main body 20 are used. Since the driving unit 20 is the same as the mixer body 20 of FIG. 1 disclosed through the prior art Patent Publication No. 2003-0028105, a detailed description thereof will be omitted. However, it is not limited to the driving unit of the type shown in the above Patent Publication, and may be configured in any form as long as the rotational force of the motor can be transmitted through the coupling.

5 is a cross-sectional view of the support part 100 and the vacuum generator 30 built in the support part 100 according to the present invention. The vacuum generator 30 according to the present invention differs only in that it is built in the support part 100, and its configuration and operation principle are the same as those disclosed through the prior art publication 2003-0028105. Detailed description of the configuration will be omitted. However, the vacuum generating device is also not limited to the form disclosed as an embodiment in the published patent publication, but only a configuration capable of sucking air by receiving the rotational force of the motor as a coupling, the conventional Patent Publication No. 10 Any type of material may be used, even those shown in -0450852.

According to the present invention, the support part 30 in which the vacuum generating device 100 is incorporated has a tapered structure in which a diameter increases from the top to the bottom, and an air suction part 110 is formed at one side. The air suction unit 110 is formed to communicate with the pump suction port 37 of the vacuum generating device 30, it is formed to protrude outward so that the tube 41 can be fitted.

The dustproof part 140 is coupled to the lowest end of the support part. The dustproof part 140 is formed of a material having elasticity, it is preferable that the dustproof rubber is used. The dustproof part 140 is a component for absorbing vibration and noise generated when the vacuum pump 39 operates.

As shown in FIG. 7, the support part 100 may have a liquid accommodating part 120 formed therein. Referring to FIG. 7, unlike FIG. 6, the air suction unit 110 and the pump suction port 37 are directly connected to each other, and the liquid receiving unit 120 having a predetermined space between the air suction unit 110 and the pump suction port 37 is shown. It can be seen that is formed. The liquid receiving unit 120 has a drip tray 130 in which a liquid such as soup can be collected at a lower portion thereof, and the drip tray 130 is slid out to the outside of the support unit 100 to allow access. It is preferable to form the handle 131 on the outside to facilitate the removal and insertion of the 130.

Since the drip tray 130 is a portion that can be moved in and out of the support part 100, when the drip tray 130 is inserted into the support part 100, air may leak between the drip tray 130 and the outside of the support part 100. The gap is easy to occur, it is important that the gap does not occur because the vacuum packaging process is not made smoothly, the space between the outside of the drip tray 130 and the support portion 100 does not occur.

6 and 7 illustrate a state in which the mixer main body 20, that is, the driving unit 20, is coupled to the vacuum generator 30 embedded in the support unit 100. At the time of coupling, the coupling protrusion 71 of the upper portion of the vacuum generating device 30 is fitted into the coupling groove 73 of the driving unit 20, so that the coupling is performed, and the coupling protrusion 71 and the coupling groove 73 are coupled to each other. By the coupling position is precisely fixed by the upper coupling 32 and the lower coupling 24 can also be accurately engaged.

The driving unit 20 is coupled to the upper portion of the vacuum generator 30. The combined cross section is shown in FIGS. 6 and 7 as described above. At this time, the coupling protrusion 71 of the upper portion of the vacuum generator 30 operates the limit switch 72 to drive the motor 22. When the motor 22 is driven, the lower coupling 24 rotates, and the upper coupling 32 meshing with the lower coupling 24 also rotates.

The upper coupling 32 and the lower coupling 24 are referred to here for the purpose of unity with the terminology used in describing the prior art of FIG. 2.

When the upper coupling 32 rotates, the small diameter gear 34 positioned on the opposite side of the same axis also rotates, and the small diameter gear 34 rotates the large diameter gear 33 and the large diameter. The gear 33 moves the eccentrically coupled rod 35 and the piston 36 coupled to the rod 35. When the piston 36 reciprocates, the air suction part 110 sucks the air into the pump suction hole 37, and the air suction part 110 is connected to the vacuum container through the tube 41. Therefore, in the end, the air inside the vacuum vessel is sucked into the pump suction port 37.

When the liquid receiving part 120 is located inside the support part 100, in the process of moving the air introduced into the air suction part 110 to the pump suction hole 37, the liquid is collected in the drip tray 130. The liquid does not move toward the pump 39, so that the failure of the vacuum generator 30 can be prevented.

The drip tray 130 can be separated by holding the handle 131 and sliding to the outside of the support part 100, so that the collected liquid is discarded and then inserted again.

When the vacuum in the vacuum container 8 is completed, the rod 64 of the pressure switch unit 60 rises due to the pressure difference, and comes into contact with the switch 65, thereby causing the motor 22 to stop automatically. do. The structure of the pressure switch unit 60 is also described in detail through the prior art Patent Publication No. 2003-0028105.

If the drive unit 20 is to be used as a mixer, it may be used in combination with the grinding blade 90 as shown in FIG. The coupling method is the same as the coupling method with the vacuum generator 30.

When not using the drive unit 20 is stored in a state coupled to the upper portion of the vacuum generator 30 built in the support unit 100, in this case, since the support unit 100 simply serves as a cradle, easy Storage is possible.

The effects of the present invention are summarized as follows.

First, the vacuum generator is built in the support, and by allowing the support to act as a cradle for the mixer drive, it is easy to store the mixer drive and the vacuum generator.

Secondly, since the vacuum generating device is built in the support part, a separate storage device is not required, thereby reducing the cost used to manufacture the device for storage.

Third, when the liquid receiving portion is formed inside the support portion, the liquid does not flow into the vacuum generator, thereby preventing a failure.

Fourth, when the drip tray is detachably coupled to the liquid container, it is easy not only to empty the soup but also to facilitate the cleaning.

Fifth, vibration and noise generated in the vacuum generator by the vibration is reduced.
