出されるため弛みを生じない。Next, the present invention will be explained in detail. When the sealed case 4 is pulled out, the microswitch 12 detects this and supplies a current in a predetermined direction to the winding 22 of the two-way electromagnetic valve 14, causing the valve body 27 on the air introduction pipe 15b side to resist the coil spring 28. It is attracted to the iron core 21 side. As a result, the atmosphere introduction pipe 15b
Since the atmosphere is introduced into the sealed case 4 through the communication tube 10 and the flexible tube 8, the lid 5 can be opened easily. When the closed case 4 is pulled out, the flexible tube 8 is wound around the guide roller 9 and is pulled out together with the guide roller 9, so that no slack occurs.

磁コイル３６がらの電磁力を受けて往復動を開始する。When food is placed in the airtight case 4 and the lid 5 is closed and pushed in, the microswitch 12 is activated and the winding 2 of the electromagnetic two-way valve 14 is activated.
2 is supplied with a current in the opposite direction to that described above, and a driving current is also supplied to the electromagnetic coil 36 of the vacuum pump 16. As a result, the direction of magnetization of the iron core 21 is switched, the valve seat 26 on the air introduction pipe 15b side is closed, the valve seat 23 on the air suction pipe 15a side is opened, and the sealed case 4 is closed to the flexible pipe 8 and the valve seat 23 on the air suction pipe 15a side. It is connected to a vacuum pump 16 via a communication pipe 10. At the same time, the piston 34 of the vacuum pump 16 receives electromagnetic force from the electromagnetic coil 36 and starts reciprocating.

真空度に保持される。That is, when the piston 34 descends, the suction valve 32 is closed and the pressure inside the volume chamber 44 increases, so the discharge valve 39 is opened and air is discharged. On the other hand, when the piston 34 rises, the volume of the volume chamber 44 increases and its pressure decreases, so the discharge valve 39 is closed and the suction valve 3
2 opens against the coil spring 33 and air enters the volume chamber 44. By repeating this process, the air inside the sealed case 4 is sucked out, and the inside of the case becomes a vacuum. Then, after a predetermined period of time has elapsed, the power supply to the vacuum pump 16 and the electromagnetic two-way valve 14 is turned off by, for example, a timer (not shown). As a result, the valve bodies 24 and 27 of the two-way electromagnetic valve 14 are pressed against the corresponding valve seats 23 and 26 by the coil springs 25° 28, so that the inside of the sealed case 4 is maintained at a predetermined degree of vacuum.
なお、真空ポンプ１６および電磁二方弁１４への給電制
御を手動にて行うようにしてもよいことは言うまでもな
い。It goes without saying that the power supply to the vacuum pump 16 and the electromagnetic two-way valve 14 may be controlled manually.

This prevents food from oxidizing and allows it to be stored for a long period of time. In this case, the food does not require any special packaging beforehand and can be stored as is, which is extremely convenient in practice.

On the other hand, in terms of structure, electromagnetic vacuum pumps have the advantage of being smaller, lighter, and cheaper than reciprocating or rotary vacuum pumps using electric motors. Further, by making the natural frequency of the combination of the piston and the coil spring equal to the frequency of the drive current supplied to the electromagnetic coil, power consumption can be minimized. Furthermore, by making the valve body of the electromagnetic two-way valve made of a rubber magnet, it makes good contact with the valve seat and is suitable for maintaining a vacuum. The effect is remarkable.
