In addition, with the recent trend of nuclear family and the trend of shopping at weekends in large discount stores and storing more than a week of food in the refrigerator, sales of household vacuum packaging machines are increasing.

Among the vacuum packaging machines, there is a Korean Patent Publication No. 1996-0013082 (September 30, 1996) `` A device for vacuum sealing a plastic bag. '' The vacuum channel portions 34 and 40 formed by the elastic seal 39 described in connection with FIG. 8 of the above patent (in the specification of the above patent, use the term chamber instead of channel) are the suction of the pump. It is connected to the nozzle to suck the air inside the pack from the inlet of the vacuum pack located in the channel portion during the pump operation to vacuum the pack. However, since the length of the vacuum channel portion corresponds to the total length of the inlet of the vacuum pack, the volume of the vacuum channel portion is so large that the concentration of the vacuum pressure applied to the inlet of the vacuum pack is lowered, so that a larger capacity pump for high speed vacuum This can lead to increased power consumption, increased noise, and larger vacuum packaging machines.

The vacuum channel of the above patent is a 'full' open channel as compared to the 'partial' open channel of the present invention.

Meanwhile, Korean Utility Model Registration No. 0322449 (2003.07.28), `` Vacuum Packing Machine '' can solve the problem of the vacuum packing machine having the 'all' open vacuum channel. 4, a separate suction nozzle 11 connected to the vacuum pump is provided in the center of the vacuum channel. However, in the registration proposal, the concentration of the vacuum pressure for evacuating the vacuum pack can be increased due to the suction nozzle, but there is an inconvenience in that the user must open the inlet of the vacuum pack and insert it into the nozzle.

The present invention solves the problem that the concentration of the vacuum pressure in the packaging machine with a large volume of the vacuum channel in the conventional vacuum packaging machine as described above and the inconvenience of having to insert the vacuum pack into the nozzle in the packaging machine equipped with a separate suction nozzle at once. It is proposed to.

Accordingly, an object of the present invention is to introduce a volume reduction means for reducing the volume of a vacuum channel that provides a vacuum space for a vacuum pack to a vacuum packaging machine.

In addition, an object of the present invention is to introduce a vacuum packaging machine in which the channel volume reduction means is a packing member for the convenience of manufacturing.

Furthermore, the guide means for locating the inlet of the vacuum pack correctly in the reduced channel, the induction channel for the liquid flowing out of the contents of the vacuum pack during vacuuming, and the liquid from entering the pump through the suction nozzle in the induction channel. The purpose of the present invention is to improve the convenience of the vacuum packaging machine by introducing a filtering means.

In addition, a pipe connecting the suction nozzle and the pump communicating with the inlet of the vacuum pack to the packaging machine main body is formed on one side of the packaging machine, and the adapter is adopted in each hole of each pipe cutting portion, Multi-functional vacuum packaging machine to connect the filtration means for the liquid filtration, the vacuum releasing means for vacuum release of the vacuum channel after using the packaging machine, and the connector for the packaging machine for a separate container vacuum The purpose is to provide.

In order to achieve the above object, a vacuum packaging machine having a partially open vacuum channel according to the present invention comprises: a main body; A hood hinged to the body; A heater installed in the main body or the hood and engaged with the pressing member arranged at a corresponding position of the hood or the main body to heat-bond the vacuum pack; Packing members arranged at positions corresponding to each other on the main body and the hood to block the inlet of the vacuum pack to be evacuated from the outside; A vacuum pump connected to the suction nozzle communicating with the inlet of the vacuum pack; And a connecting slit formed on the main body portion or the hood portion where the packing member is located, or both thereof, and a connecting slit communicating with the suction nozzle of the vacuum pump, wherein the suction force of the vacuum pump passes through the suction nozzle. And a vacuum channel transferred to an inlet of the vacuum pack positioned between the hoods to form a vacuuming space for evacuating air inside the vacuum pack . A control unit for the heater and the vacuum pump; And a channel volume reducing means for reducing the volume of the vacuum channel to increase the concentration of the vacuum pressure by the pump.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In each figure, a member having the same reference numeral, in particular, a member having the tenth and oneth digit indicates a member having the same function. .

First, in Figure 1, the vacuum packaging machine (V1) according to the present invention consists of a main body 10 and a hood 20 hinged to the main body 10. Typically, the main body 10 is provided with a heater 30 that can heat-bond the inlet of the vacuumized vacuum pack (not shown), and the hood 20 has the heater 30 at a corresponding position. In combination with the pressing member 31 for pressing the inlet of the vacuum pack is provided. However, the present invention is not limited by the installation position of the heater and the pressing member.

In addition, after the vacuum pack is positioned and the main body 10 and the hood 20 are engaged with each other, a vacuum pump (not shown) is automatically applied by operating buttons 17a and 17b or by sensing pressure applied to the hood. When operated, a vacuum channel, which is a part of which vacuum pressure is applied by the suction nozzle 41 connected to the pump, is formed, and a packing member is provided in the main body 10 and the hood 20 to block the inlet of the vacuum pack from the outside. It is. Although the suction nozzles are illustrated as being arranged in one, two or more suction nozzles may be arranged at intervals corresponding to the inlet length of the vacuum pack.

In FIG. 1, the packing member arranged on the main body 10 is a linear packing member 11.

In addition, the packing member 21 arranged in the hood 20 may include openings 21a and 21b for suction nozzles 41 and 41b connected to the pump to partially open the vacuum channel. 21c, 21d, and 21e are formed to serve as channel volume reduction means that form the core of the present invention.

The packing member 21 arranged on the hood 20 is fitted to contact the inner circumferential surface of the fixing member 23 having the same shape as the outer shape of the packing member. The actual vacuum channel C is formed by the packing member 21, which is a channel volume reducing means, in contact with the openings 21a, 21b, 21c, 21d of the packing member 21, and the rear surface of the packing member 21. It is the connection slit C1 which connects each opening part.

The vacuum channel C having such a reduced volume is in communication with the suction nozzle 41 by the connecting slit C1, so that the vacuum pressure can be applied to the channel C. The connecting slit C1 is in the form of a slim rectangular groove as a whole, and both ends of the slit have an expansion part C2 for the opening nozzles 21a and 21b of the suction nozzle 41 and the packing member 21 corresponding thereto ( C3).

The connection slit C1 is illustrated as being formed in the hood 20, but may alternatively be formed in the packing member 21 to connect each opening. However, when the slit is formed in the compressible packing member 21, the slit may be blocked by the pressurization, so that the vacuum pressure may not be applied to all the openings. As shown in the drawing, the slit C1 is applied to the hood 20. It is preferable that this is formed.

In the drawing, the vacuum channel C is eventually formed only in the hood 20, but the channel may be formed only in the main body or may be formed in both the main body and the hood.

3A and 3B, packing members 121A and 121B having a different shape from those of FIG. 1 are shown. The packing members 121A and 121B also function as channel C volume reduction means. First, in FIG. 3A, the packing member 121A includes a plurality of openings 121c disposed at regular intervals, including openings 121a and 121b for the suction nozzle 41. In addition, the packing member 121B shown in FIG. 3B also has openings 122c open to each other, including openings 122a and 122b for suction nozzles.

If necessary, the vacuum channel volume reducing means may be a separate member from the packing member 21.

On the other hand, the main body 10 does not need to match the inlet of the vacuum pack with the vacuum channels C, in particular, the openings 21a, 21b, 21c, 21d, 21e of the packing member 21 to enhance convenience. In order to guide the inlet of the vacuum pack to a position corresponding to the vacuum channel (C) is provided. The guide member has a shape of a plurality of locking protrusions 15.

Next, as shown in Figures 1 and 2a, the vacuum packaging machine (V1) according to the present invention is a vacuum release means for opening the hood 10 by releasing the vacuum in the vacuum channel after packing the vacuum pack Filter means for filtering the liquid coming out of the contents contained in the vacuum pack during the vacuum so as not to flow into the pump through the suction nozzle 41, and the vacuum pump and the suction nozzle (41) for connection to the connector for a separate container vacuum ), A pipe connecting a) is exposed to one side of the main body 10, the right side to form a cut portion (A43) (A45) to connect the adapter (A1) to each cut portion.

The adapter A1 has a projection 43a fitted to the cut portion A43 of the pipe P1 connected to the pump and a projection 45a fitted to the cut portion A45 of the pipe P2 connected to the suction nozzle 41. Have The adapter A1 is placed in the fitting groove A2 formed in the main body 10.

First, the use of the adapter (A1) is to connect the suction nozzle 41 and the pump during the normal vacuum packaging of the packaging machine (V1) so that the suction force can act on the nozzle, the inlet (43) and outlet of the adapter (A1) The inlet and the outlet are communicated with each other by coupling with the connecting member 60 having the projections 61a and 61b coupled to the 45.

Another use of the adapter A1 is in connection with filtration means, which prevents the liquid exiting the contents of the vacuum pack from entering the pump via the suction nozzle 41. The filtering means may be a form embedded in the main body, but it is preferable that the filtering means 70 of the external type as shown in Figure 2b for the convenience of cleaning or replacement.

Prior to the description of the filtering means, in order to prevent the liquid derived from the contents contained in the vacuum pack from flowing out through the inlet of the vacuum pack and contaminating the vacuum packaging machine, the liquid induction channel was introduced into the packaging machine. As shown in FIG. 5, the liquid induction channel has a shape inclined so that liquid flows toward the suction nozzle 41 as 213 formed in the main body 210 itself of the packaging machine V2. When the suction nozzles are arranged at both ends of the inlet of the vacuum pack, the liquid induction channel may have a high intermediate point and lower toward each nozzle.

However, in the liquid induction channel 213 formed in the main body 210 of the vacuum packaging machine (V2) shown in FIG. 5, contaminants remain and are inconvenient to clean and replace. In order to solve this problem, the suction nozzle 141, the vacuum pack guide member 115, the linear packing member 111, and the liquid induction channel 113 may be separated from the separated body S. The channel 113 is inclined toward one nozzle 141 as shown in the confirmed circle. In addition, the main body should be provided with a settled portion of a corresponding shape for the separator (S), and the settling portion should be arranged with a connection with the suction nozzle 141.

Thus, the liquid introduced into the nozzles 141 and 241 through the liquid induction channels 113 and 213 shown in FIG. 4 or 5 is filtered by the filtering means so as not to flow into the pump. The filtration means 70 shown in FIG. 2B has a housing having coupling protrusions 75a and 75b engaged with the inlet 43 and the outlet 45 of the adapter A1 fitted to the pipe connecting the nozzle and the pump. (71), a cover (75) having a filter (75) embedded in the housing (71), and a protrusion (73a) fastened to the coupling groove (71a) of the housing (71). Such a filter means is easy to clean and replace, and can reliably prevent the liquid of the contents of the vacuum pack from flowing into the vacuum pump.

Another use of the adapter A1 is for a connector (not shown) which allows the pump of the vacuum packaging machine to be used for evacuating an external vacuum vessel.

Subsequently, the vacuum packaging machine according to the present invention preferably further includes a vacuum release means for easily opening the hood by releasing the vacuum state of the vacuum channel after the vacuum and heat bonding of the vacuum pack. In the conventional vacuum packaging machine, the vacuum is released by opening and closing the hole formed in the upper portion of the hood and communicating with the vacuum channel inside the hood by a valve. However, the position of the conventional vacuum releasing means has a problem that the user is easy to release the vacuum state unconsciously touching the valve in the process of the user presses the hood to close to the main body.

In order to solve this problem, as shown in FIG. 1, the vacuum releasing means 50 of the present invention is arranged on the side of the main body 10. In order to release the vacuum state of the vacuum channel C, a vacuum release nozzle 53 is formed on the main body 10 and communicates with a pipe P2 connected to the suction nozzle 41. The vacuum release nozzle 53 is limited in position by fitting projections 52a formed on both sides of the opening and closing lever 51 into the slide groove 52b of the main body 10, and the lever 51 and the main body 10. Since the lever is supported by the spring 51a interposed between the side walls of the user, when the user presses the lever 51 to the left side, the lever 51 is opened and the opening / closing portion (not shown) of the lever 51 moves to the nozzle. By opening 53, air is introduced through the vacuum release nozzle 53, the connecting pipe P2, the suction nozzle 41, and the channel C in order to release the vacuum state of the channel C. Subsequently, when the lever 51 is released, the lever returns by the elastic force of the spring 51a to close the nozzle 53 again.

Hereinafter, an operating state of the vacuum packaging machine V1 according to the present invention will be described with reference to FIG. 1. When the inlet of the vacuum pack is placed on the upper part of the main body 10 and pushed backward, the inlet of the vacuum pack is openings 21a, 21b, 21c of the packing member 21 positioned in the hood 20 by the protrusions 15 as guide members. , 21d, 21e). In the state in which the connecting member 60 is coupled to the adapter A1 as shown in FIG. 2A, the pump is operated by covering the hood 20 and pressing the operation switch 17a to apply a suction force to the suction nozzle 41. A vacuum pressure is also applied to the opening of the connecting slit C1 and the packing member 21 in communication with the nozzle 41. Subsequently, when a vacuum pressure is applied to the inlet of the vacuum pack through the opening, the air inside the pack escapes and the inside of the pack is evacuated. At this time, the vacuum channel (C) of the packaging machine (V1) according to the present invention can increase the concentration of the vacuum pressure applied to the inlet of the channel (C) and the vacuum pack due to the packing member 21 which is a volume reduction means.

When the vacuum of the vacuum pack is made to some extent, the pressure sensor detects this and calculates it in the controller to automatically stop the operation of the pump. Then, the heater 30 is operated by the controller to heat-bond the inlet of the vacuum pack. Alternatively, the pressure may be visually checked on the exposed gauge and the pump may be manually turned off to stop the pump, and the heater 30 operation button may be turned on to heat-bond the inlet of the vacuum pack.

Then, by pressing the lever 51 of the vacuum release means 50 to open the hood 20 to open the vacuum release nozzle 53, the vacuum state of the channel C is released and the vacuum pack is removed from the main body 10. Serve

As described above, a true fear organ having a partially open vacuum channel according to the present invention can reduce the volume of the vacuum channel providing a vacuum space for the vacuum pack due to the channel volume reduction means, thereby increasing the concentration of the vacuum pressure. Both the disadvantages of the vacuum packaging machine with the 'full' open vacuum channel and the packaging machine with the nozzle fitted at the inlet of the vacuum pack can be solved.

In addition, the guide means to help the inlet of the vacuum pack accurately located in the reduced channel, the induction channel for the liquid flowing out of the contents of the vacuum pack during vacuum, and the liquid to prevent the liquid from entering the pump through the suction nozzle in the induction channel The main filter introduces a filtering means to enhance the convenience of the vacuum packaging machine.

In addition, a pipe connecting the suction nozzle and the pump communicating with the inlet of the vacuum pack to the packaging machine main body is exposed to one side of the packaging machine to form a cutout, and an adapter is adopted in each hole of each cutout of the pipe. Multi-functional vacuum packaging machine to connect the filtration means for the liquid filtration, the vacuum releasing means for vacuum release of the vacuum channel after using the packaging machine, and the connector for the packaging machine for a separate container vacuum Can be provided.

In the above description of the present invention, a vacuum packaging machine having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be variously modified and changed by those skilled in the art, and such variations and modifications are within the scope of protection of the present invention.
