U.S. Patent No. 4,941,310 to Tillia (August 17, 1990) `` APPARATUS FOR VACUUM SEALING PLASTIC BAGS '' (Related Korean Patent No.0109619 (1996.12.23),

Korea Utility Model Registration No. 0165428 (1999.10.18) by Chu Yeon 『Vacuum Packing Machine』,

Korea Utility Model Registration of the Eiffel Industry No. 0322449 (2003.07.28) 『Vacuum Packing Machine』,

Registered by Korea Utility Model No. 0378218 (2005.03.02), `` Air intake type vacuum packaging machine ''.

As such, the conventional vacuum packaging machine in which the air inlet is arranged on the base frequently causes malfunctions and failures of the vacuum pump due to the inflow of the liquid component of the contents slid downward by gravity into the vacuum pump through the air inlet.

In order to solve this problem, technologies for installing a separate filter in the middle of the connection between the vacuum pump and the air inlet or introducing a storage space in which the liquid contents can be stored have been introduced. However, the improvement is due to the complexity of the vacuum packaging machine and the difficulty of cleaning. It has been pointed out to cause problems that harm the hygiene.

The present invention has been proposed to solve the problem of a vacuum packaging machine having an air inlet is arranged in the conventional base.

Accordingly, an object of the present invention is to provide a vacuum packaging machine in which an air inlet is arranged in a hood to prevent the liquid contents from being sucked into the vacuum pump through the air inlet during the vacuum of the packaging bag to contaminate the pump and cause a pump failure. .

In another aspect, the present invention provides a vacuum packaging machine incorporating a locking means for fixing the engaged state of the hood and the base, and is formed when the base and the hood are engaged, the closed space in which the vacuum pressure by the operation of the vacuum pump is applied ( S) The heater is arranged inside to minimize the loss of the horror white and to realize the compact structure.

In order to achieve the above object, a vacuum packaging machine having an air inlet arranged in a hood according to the present invention has a rectangular base; A hood having a corresponding shape to cover an upper surface of the base and coupled through a hinge with the base; A sealed space forming member which forms a sealed space when the base and the hood are engaged, and includes a concave portion out of a imaginary plane formed by a contact surface of the engaged base and the hood; A vacuum pump connected to an air suction port and a connection pipe positioned in the sealed space forming member arranged in the hood to generate a vacuum suction input in the closed space during operation; A heater arranged in a rectangular shape on the base or the hood, or both, to heat and laminate the vacuum packaging bag; And a control unit for controlling the vacuum pump and the heater.

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

In the following description of the present invention with reference to the drawings, the same reference numerals, in particular, the tens and ones place, or the tens, ones place and the same reference numerals, refer to a member having the same function.

First, as shown in Figures 1a and 1b, the vacuum packaging machine (V1) having an air inlet arranged in the hood according to the invention has a rectangular shape as a whole, the longitudinal direction is axial through the hinge (BH) provided on both sides The rectangular shape of the base 10 and the hood 20 to be opened and closed is to ensure a heater and a sealed space at least longer than the width of the vacuum packaging bag.

In the vacuum packaging machine shown in FIGS. 1A, 1B, and 2, the vacuum pump 40 and the heater 50, which are the core members of the vacuum packaging machine, are arranged in the base 10, and the sealed space S forming member. 30 is arranged in the hood 20, but the present invention is not limited by the arrangement of the components.

The member 30 for forming the closed space S, which is formed when the base 10 and the hinge 20 are engaged, has a long closed loop recess in the hood 20. It consists of (31), the circumference of the recess is provided with a packing member 33 for improving the airtightness.

In addition, the base to form a closed space (S) by closing the opening of the concave portion 31, which is a forming member 30 for the closed space deviated from the imaginary plane formed by the contact surface of the base and the hood ( The portion of 10) is also provided with a plate-shaped packing member 35 for improving the airtightness.

In particular, the plate-shaped lower packing member 35 has a narrow width that abuts the front portion of the closed loop packing member 33 arranged in the hood.

In order to position the inlet of the vacuum packaging bag located in the sealed space exactly in the middle of the sealed space S, it is preferable that stoppers 35 arranged in a left and right row are formed in the middle of the lower packing member 35. .

The sealed space forming member may be provided only in the base, or may be modified in the form of a concave portion formed in both the base and the hood.

1A and 2, the vacuum pump 40 is configured to apply a vacuum suction input to the closed space S formed when the base and the hood are engaged to allow air to be discharged through the inlet of the vacuum packaging bag. It is connected to the air suction port 41 arranged on the upper surface of the concave inlet portion 31 of the hood (20). In order to connect with the vacuum pump 40 arranged in the base 10, the connecting pipe 43 should be connected to the air intake port 41 through a hinge (BH) coupling part, which is a connection part of the base and the hood. (Not shown).

In particular, although one air inlet 41 connected to the vacuum pump 40 is illustrated as being arranged on the right side of the concave inlet part 31 in FIG. 1B, a plurality of air inlets are spaced apart from the closed space S, in particular, the hood. It is preferably formed so that a uniform vacuum suction input is applied to the entire sealed space S.

In addition, since the air inlet 41 connected to the pump 40 is arranged inside the inlet 31 of the hood 20, when the contents contained in the vacuum packaging bag contain liquid, the liquid contents are applied to the suction force of the pump. There is a problem that pump contamination, malfunction, or failure caused by entering the pump through the air inlet, and the lower packing arranged on the bottom, that is, the base 10 without the liquid content does not enter the air inlet by gravity without a separate filter member Since it remains in the member 35, it can be prevented.

In the vacuum packaging machine V1 according to the present invention, an arrangement position of the heater 50 may be arranged in the sealed space S. For this purpose, in FIG. 1B, the heater 50 may include the base 10 and the hood. When the 20 is engaged, it is arranged in the middle part, especially the base 10, in which the closed space S is formed, and in the center of the recessed part 31 of the hood 20 is engaged with the heater 50 arranged in a vacuum. A pressing member 51 made of a special synthetic resin such as heat resistant silicone or Teflon is arranged so as to weakly press the inlet portion of the packaging bag.

The degree to which the heater 50 and the pressure member 51 are engaged to pressurize the inlet of the vacuum packaging bag is limited so as not to severely inhibit the suction of the air inside the vacuum packaging bag by the vacuum pump 40.

Due to the arrangement of the heater 50 as described above, as compared with the case in which the heater is arranged outside the sealed space as in the conventional vacuum packaging machine, the waste of the vacuum packaging bag can be reduced and a more compact vacuum packaging machine can be realized.

The heater 50 and the vacuum pump 40 are controlled by a controller 70, in particular a microprocessor to which a series of processes are input.

In addition, after the vacuum packaging bag is laminated by the heater 50, the air is introduced into the sealed space S on which the vacuum suction input is applied, so that the opening operation of the base 10 and the hood 20 can be easily performed. It is preferable to further include a release means.

In addition, the lever 81 is provided on both sides of the engaging projection (81a) to be fitted into the coupling hole (85a) of the housing 85 to serve as a rotation shaft, the lever (81) of the hood (20) A restoring spring 81B is provided to connect the mounting piece 81b and the mounting protrusion 85d formed at the bottom of the housing 85 to provide a restoring force to the lever (see FIG. 3B).

In FIG. 3B, the hook 81A of the lever 81 penetrates through the slot 39 provided on the base 10 and is caught by the inner wall.

In addition, the button 83 is exposed to the upper surface of the hood 10 to press the lever 81, and the anti-separation protrusions 83a are radially formed at the bottom thereof.

The locking means 80 shown in FIG. 3A is also applied to the vacuum packaging machine V1 shown in FIGS. 1A and 1B except for the vacuum releasing means 260. In FIG. 1A, the upper both sides of the hood 20 are shown. The button 83 is exposed, the hooks 81A are exposed on both lower sides of the hood 20 in FIG. 1B, and the slots 39 can be hooked to the upper surface of the base 10. ) Is formed.

The housing 263 is installed on the base 10, and has a coupling hole 263a into which the engaging projection 261a of the lever 261 serves as a pivot shaft, and is formed between the lever 261 and the lever 261. The support spring 261b is installed to provide elastic restoring force of the lever.

The pressurizing portion 261A of the lever 261 is pressurized on the rear surface of the hook 81A when the lever 81 of the locking means 80 is pressed, so that the packing disc 261B receives air into the housing 263. 263A) is opened to allow air to enter the enclosed space (S).

In the vacuum packaging machine in which the heaters are arranged in the sealed space S as described above, as shown in FIG. 1B, the hood 10 and the base 20 are coupled to each other by the “rear hinge” BH. Not only can be applied to the form made, but also the combination of the hood 110 and the base 120, such as in the vacuum packaging machine (V3) shown in Figure 4 may be applied to the form made by the "side hinge" (SH).

More precisely, the "rear hinge" arrangement refers to a form in which the base and the hood are engaged with each other by pivoting in the longitudinal direction of the rear surface, and the "side hinge" arrangement refers to a rotation in one axis of one side as the axis. Refers to meshing with the hood.

The vacuum packaging machine (V1) adopting the “rear hinge” (BH) arrangement method as the base and hood combination method is used to seal the heat seal at the inlet of the vacuum packaging bag following the evacuation caused by the discharge of the air inside the vacuum packaging bag using the vacuum pump. It is suitable for the vacuum bag packaging process that is applied sequentially, which is not suitable for the unique use of the heater in the vacuum packaging machine. There is a problem that the suture itself is impossible.

In contrast, the vacuum packaging machine V3 employing the “side hinge” (SH) arrangement method includes a rectangular base 10 that contacts the support surface of a sink, a dining table, a work table, and the hood 20 covering the base 10. The connection is made through the side hinge (SH), so that it is possible to make a long spaced heat seal without cutting the packaging bag regardless of the vacuum process.

In other words, the "side hinge" (SH) vacuum packaging machine (V3) is a vacuum process, whereas the vacuum packaging machine (V1) of the "back hinge" (BH) arrangement is suitable for sequentially undergoing the post-vacuum heat sealing process of the vacuum packaging bag. Regardless, as shown in FIG. 5A, it is possible to make a long sparse heat seal B2 without cutting the packaging bag B wound in the form of a roll R (in FIG. 5B. In addition, as shown in FIG. 5B, the contents B3 are put into the vacuum packaging bag B, and a portion of the packaging bag is heat-sealed (B2) while the inlets are sealed and cut. It is possible to heat seal the bag by fourteen minutes so that the vacuum bag is divided into four parts in such a state that it is not sandwiched between the sheets constituting the bag.

In addition, as shown in Figure 4, the vacuum packaging machine (V3), in particular the hood 120 is equipped with a cutter (C) is convenient to cut the packaging bag before or after vacuum packaging. The cutter can be replaced with small scissors.

The cutter (C) is mounted to the mounting portion (C4) of the hood in a sliding manner, in order to prevent the human body such as fingers from being cut off, the blade (C1) is masked so as not to be directly exposed by the two projections (C2a, C2b). In addition, the blade (C1) is arranged in an inclined form can be prevented from occurring a problem in the cutting force due to increased friction with the packaging bag to be cut, and also has a non-slip projection (C3).

At this time, the engaged state of the base and the hood is fixed by the locking means, it is convenient because the user does not need continuous pressing.

The operation of the vacuum pump 40 may be made by a sensor that senses the pressure pressing the hood, not the switch method.

At this time, the concave portion 31, which is a forming member 30 for the sealed space out of the imaginary plane formed by the contact surface of the base and the hood engaged is arranged in the hood 20, the pump 40 and Since the connected air inlet 41 is also arranged inside the inlet 31 of the hood 20, when the content contained in the vacuum bag contains liquid, the liquid content passes through the air inlet by the suction force of the pump to the pump. The problem of pumping, malfunction, or failure due to inflow may be such that the liquid contents do not enter the air inlet by gravity without remaining a separate filter member, and remain on the bottom, that is, the lower packing member 35 arranged on the base 10. Can be prevented.

Subsequently, when the air is discharged to some extent within the packaging bag, the heater 50 is operated through the pressure sensing of the closed space S by a sensor.

When the sealing of the inlet rear of the vacuum bag (B) by the heater 50 is completed by the reference time measurement or the temperature sensing, a connecting pipe connecting the pump 40 and the heater 50 by the command of the controller. The three-way valve 161, which has opened the conduit of (43), closes the pump-side conduit by the operation of the solenoid and connects the air inlet hole 163 formed on the hood 20 to the air intake port 41. It will open the pipeline.

Accordingly, the outside air flows into the sealed space S to release the vacuum of the sealed space, thereby completing the vacuum packing.

As described above, the vacuum packaging machine having the air inlet arranged in the hood according to the present invention prevents the liquid contents from being sucked into the vacuum pump through the air inlet during the packaging of the vacuum bag to contaminate the pump and cause the pump to malfunction. can do.

In addition, the present invention is formed when the base and the hood is engaged, and the heater is arranged in the closed space (S) in which the vacuum pressure by the operation of the vacuum pump acts to minimize the loss of the vacuum packaging bag and to realize a compact structure. In addition, the present invention can be easily fixed to the engaged state of the hood and the base through the locking means.

In the above description, a specific well-known technology related to the operation and control relationship of the vacuum packaging machine is omitted, but those skilled in the art will be able to speculate or infer this.
