A check valve 14 having a flexible valve plate is mounted on the inner surface of the connection port 12. The check valve 14 is normally closed and is opened when the decompression chamber 9 has a negative pressure. An air discharge hole 15 is formed on the side of the connection port 12 (fourth
(See FIG. 5), a check valve 16 having a flexible valve plate is mounted on the outer surface of the air discharge hole 15.

Inside the decompression chamber 9, a bellows 17 having a volume almost equal to that of the chamber is housed. The lower end of the bellows 17 is held by a holding frame 18 fitted on the inner circumference of the holding member 8. A hole 19 is formed in the portion of the device substrate 7 surrounded by the holding frame 18 to open the inside of the bellows 17 to the atmosphere. A coil spring 17 'is mounted inside the bellows 17.

An upper end of the bellows 17 is fixed to a pressing plate 20, and a pressing rod 21 is provided on the pressing plate 20 so as to project. Presser bar 21
Penetrates the decompression chamber 9 upward while maintaining an airtight state. The upper end of the presser bar 21 is inserted into a boss portion 24 of a lock member 23 provided on the lower surface of the oblong box-shaped operation member 6.

The operation member 6 is inserted into the opening portion of the horizontal panel 4 and moves up and down in the gap between the outer circumference of the decompression chamber 9 and the storage case body 1. Further, a pair of opposed fan-shaped windows 26 (see FIG. 5) are formed on the upper surface of the operation member 6, and an arc-shaped guide 27 is formed on the lower surface of the outer peripheral edge of the fan-shaped window 26, and the outer periphery of the lock member 23 is formed. A partial collar 28 is provided so as to project in a centrally symmetrical position of the plane. By placing the partial brim 28 on the guide 27, the lock member 23 is supported at the upper end of the pressing rod 21 so as to freely rotate.

Small projections 29 (see FIG. 5) are formed on the lower surface of the partial brim 28, and small projections 31 are also formed on the upper surface of the guide 27. Therefore, when the lock member 23 is rotated by a certain angle or more, the small protrusion 29 of the partial brim 28 causes the guide 27 to move.
It gets over the small protrusion 31 and gives a click feeling to the fingertip.

Further, on the outer peripheral surface of the lock member 23, a pair of lock claws 32 are provided so as to project between the partial flanges 28. Further, a pair of engaging portions 33 are formed on the upper surface of the decompression chamber 9 so as to face the lock claws 32, and when the lock claws 32 engage the engaging portions 33, the operating member 6 is operated via the lock member 23. It is integrated with the upper surface of the decompression chamber 9.

A pair of knobs 34 are formed on the upper surface of the lock member 23 so as to correspond to the partial flanges 28, and each knob 34 is exposed in the fan-shaped window 26.

The decompression type storage of the embodiment is configured as described above, and in the normal state, the operating member 6 of the deaerator 5 is pushed deepest, the knob 34 of the lock member 23 is rotated with the fingertip, and the lock claw 32 thereof is rotated. Is engaged with the engaging portion 33. As a result, the operating member 6 is locked in the most pushed state (see FIGS. 3 and 6). In this state, the operation member 6
Since the upper end surface of is lower than the position of the door 3, the door 3 can be freely opened and closed (see FIG. 1).

Next, dry food (for example, dried seaweed) is stored inside the storage chamber 2.
Is stored, the door 3 is closed, and the lock member 23 is rotated in the opposite direction to unlock (see FIGS. 2 and 7). Then,
The operating member 6 is lifted by the restoring elasticity of the coil spring 17 '. At this time, the air inside the decompression chamber 9 pushes out the check valve 16 in the discharge hole 15 and is discharged. In the state of FIG. 2 in which the operating member 6 reaches the uppermost end, the door 3 hits the operating member 6 and cannot be opened.

When the operating member 6 is pushed down again from the above state, the bellows 17 contracts, and the decompression chamber 9 contracts as the bellows 17 contracts.
The inside is depressurized. Check valve 1 accompanying decompression of decompression chamber 9
4 is opened and the storage room 2 is opened through the joint pipe 11.
The air inside is sucked.

After that, the same operation is repeated several times to discharge the air inside the storage chamber 2 and reduce the pressure to the required pressure. After the operation is completed, the knob 3 of the lock member 23 is pushed in while the operation member 6 is pushed in.
4. Put your finger on 4 and rotate it, and lock the lock claw 32
Engage with 3 to lock.

When releasing the negative pressure in the storage chamber 2, the check valve 35 for releasing the negative pressure mounted on the door 3 is pulled away from the surface of the door 3 with a fingertip so that the air is absorbed inside.

[Effect of device]

As described above, according to the present invention, since the bellows operation member of the deaerator can be locked in the pushed state, the operation member can be held in the lowest posture when the deaerator is not used. Therefore, the deaerator does not stand out more than necessary, and the opening and closing of the door is not hindered.
