The upper spring 88 and the lower spring 89 press the upper flange 84 and the lower flange 85 from the upper side and the lower side, respectively, via the upper engagement ring 86 and the lower engagement ring 87, respectively.

When the upper flange 84 and the lower flange 85 move upward from the neutral position, the upper engaging ring 86 slides upward from the ridge 59 to compress the upper spring 88. Further, the upper engaging ring 86 that slides upward from the ridge 59 slides downward until it comes into contact with the upper surface of the ridge 59 due to the repulsive force of the compressed upper spring 88. Similarly, when the upper flange 84 and the lower flange 85 move downward from the neutral position, the lower engaging ring 87 slides downward from the ridge 59 to compress the lower spring 89. Further, the lower engaging ring 87 that slides downward from the ridge 59 slides upward until it comes into contact with the lower surface of the ridge 59 due to the repulsive force of the compressed lower spring 89.

As shown in FIG. 4, the operation arm 91 is formed in a U shape so as to sandwich the case 51 of the extractor 50 from the outside. Both ends of the operation arm 91 are supported by support shafts 92 fixed to the outer peripheral surface of the case 51, as shown in FIGS. 3 and 4. As a result, the operating arm 91 is configured to rotate in the vertical direction with the support shaft 92 as a fulcrum, as shown in FIG. The operating arm 91 is in a horizontal position when it is in the neutral position as shown in FIGS. 2 and 3.

As shown in FIGS. 2 and 4, the rotating pin 93 is provided substantially parallel to the support shaft 92. The rotating pin 93 is provided so as to penetrate the operation arm 91 and the case 51 from the outer side in the radial direction to the inner side in the radial direction and extend until it reaches between the upper flange 84 and the lower flange 85.

The rotation pin 93 is between the upper flange 84 and the lower flange 85 while pressing the lower surface of the upper flange 84 upward when the operation arm 91 rotates upward from the neutral position. Sliding. The rotation pin 93 presses the upper surface of the lower flange 85 downward when the operating arm 91 rotates downward from the neutral position, while pressing the upper flange 84 and the lower flange. It slides between 85. As a result, the rotation pin 93 can move the upper flange 84 and the lower flange 85 in the vertical direction in conjunction with the rotation of the operation arm 91.

The first valve 60 or the second valve 70 can be operated.

The strainer 100 is detachably provided in the container 40 of the reservoir 20 so that it can be easily handled during cleaning.

Includes a through hole 104 through which the 75 penetrates.

The filter 101 is formed by using a soft elastic material such as a silicone resin, and is provided so that the area thereof is larger than the cross-sectional area of the liquid flow path from the mouth portion B1 of the bottle B to the container 40. As a result, the filter 101 can quickly separate the precipitate contained in the liquid flowing down to the strainer 100 from the liquid, and clogging is less likely to occur.

The frame 102 is formed by using a soft elastic material such as silicone resin, and its outer peripheral surface 105 is an inner peripheral surface 47 of a container 40 located below the lower end portion 37 of the lower inner cylinder portion 33 of the connector 30. It is formed so as to have a shape along the above. Therefore, the outer peripheral surface 105 of the frame 102 is in close contact with the inner peripheral surface 47 of the container 40 located below the lower end 37 of the lower inner cylinder portion 33, and is supported by the inner peripheral surface 47 of the container 40. Thereby, the strainer 100 can surely separate the precipitate and the liquid contained in the liquid flowing down into the container 40.

Further, the outer peripheral surface 105 of the frame 102 is formed so as to have a shape along the inner peripheral surface 47 of the container 40 located above the height of the liquid surface when a predetermined amount of liquid is stored. Therefore, the outer peripheral surface 105 of the frame 102 can be in close contact with the inner peripheral surface 47 of the container 40 located above the height of the liquid surface when a predetermined amount of liquid is stored, and can be supported by the inner peripheral surface 47 of the container 40. .. As a result, the strainer 100 can prevent the precipitate separated by the filter 101 from floating in the liquid again and adhering to the space between the working rod 75 and the through hole 104, so that the working rod 75 is smooth. It is possible to reduce the possibility of hindering movement. The predetermined amount is the amount of the liquid extracted to the outside such as a glass in one operation, and is preferably in the range of 50 ml or more and 70 ml or less, for example.

The pole 103 is provided so as to extend upward from the outer edge portion of the disk portion located at the center of the frame 102. The upper end of the pole 103 is provided with a notch that abuts and engages with the lower end 37 of the lower inner cylinder 33 of the connector 30, and this notch abuts the lower end 37 of the lower inner cylinder 33. Engage. As a result, the pole 103 can suppress the upward displacement of the strainer 100.

[Embodiment 1: Operation of Liquid Extractor]
FIG. 6 is a diagram for explaining the exhaust operation of the liquid extraction device 1. FIG. 7 is a diagram for explaining the storage operation of the liquid extraction device 1. FIG. 8 is a diagram for explaining the extraction operation of the liquid extraction device 1. In FIGS. 6 to 8, the thick one-dot chain arrow indicates the gas flow, and the thick solid arrow indicates the liquid flow.

The operation of the liquid extraction device 1 when extracting the liquid contained in the bottle B installed in the installation unit 4 to the outside will be described. At this time, as the operation of the liquid extraction device 1, first, an exhaust operation is performed, then a storage operation is performed, and finally, an extraction operation is performed.

The exhaust operation is an operation of supplying the deterioration suppressing gas into the connected portion 10 and the reservoir 20 and discharging the gas in the connected portion 10 and the reservoir 20. The exhaust operation is performed with the operating arm 91 in the neutral position, as shown in FIG. When the operating arm 91 is in the neutral position, the operating rod 75 is in the neutral position, and the first valve 60 and the second valve 70 are in the inactive state.

In the liquid extraction device 1 in such a state, in the exhaust operation, the deterioration suppressing gas of the gas supply source 121 is supplied from the air supply port 13 to the inside of the connected portion 10 via the air supply pipe 122. The deterioration-suppressing gas supplied from the air supply port 13 flows into the container 40 through the air supply / exhaust passage 15 and the ventilation passage 35 while pushing out the gas such as air existing in the connected portion 10 and the reservoir 20. At the same time, the gas is discharged from the exhaust port 14 to the outside of the apparatus main body 2 through the ventilation passage 35 and the air supply / exhaust passage 15. The gas discharged from the exhaust port 14 is discharged from the exhaust pipe on-off valve 130 via the exhaust pipe 129 of the gas supply system 120. As a result, in the liquid extraction device 1, the insides of the connected portion 10 and the reservoir 20 are purged with gas such as air and filled with the deterioration suppressing gas.

In the storage operation performed after the exhaust operation, the deterioration suppressing gas is supplied into the connected portion 10 and the storage unit 20, and the liquid contained in the bottle B installed in the installation unit 4 flows down into the storage unit 20. It is an operation of letting and storing. As shown in FIG. 7, the storage operation is performed in a state where the operation arm 91 is rotated upward from the neutral position. When the operating arm 91 rotates upward from the neutral position, the rotation pin 93 moves the upper flange 84 and the lower flange 85 upward from the neutral position. Therefore, the introduction pipe 53 and the extraction pipe 54 held by the holder 81 move upward from the neutral position, and the operating rod 75 moves upward from the neutral position. When the operating rod 75 moves upward from the neutral position, the valve body 61 of the first valve 60 is moved upward, and the first valve 60 operates. At the same time, the second valve 70 remains inactive.

In the liquid extraction device 1 in such a state, in the storage operation, the difference between the pressure in the bottle B installed in the installation unit 4 and the pressure in the connected portion 10 and the reservoir 20 filled with the deterioration suppressing gas. The liquid contained in the bottle B flows down into the container 40 through the inside of the upper cylinder portion 31 and the lower inner cylinder portion 33 of the connector 30. At the same time, the deterioration suppressing gas that fills the connected portion 10 and the reservoir 20 is introduced into the bottle B through the inside of the lower inner cylinder portion 33 and the upper cylinder portion 31 of the connector 30.

The liquid that has flowed down into the container 40 flows down into the strainer 100. The precipitate contained in the liquid flowing down to the strainer 100 cannot pass through the filter 101 of the strainer 100 and is separated. The liquid that has passed through the strainer 100 reaches the bottom 42 of the container 40. At this time, since the second valve 70 is not operating and the flow-down hole 44 and the communication hole 56 of the bottom portion 42 are blocked by the valve body 71, the second valve 70 is stored in the container 40. As described above, since the storage operation is performed in a state where the inside of the storage device 20 and the like is filled only with the liquid and the deterioration suppressing gas, the quality of the liquid stored in the container 40 and the liquid contained in the bottle B is deteriorated. I won't let you.

When the liquid level of the liquid stored in the container 40 is located below the lower end 37 of the lower inner cylinder 33, that is, on the bottom 42 side, the difference between the pressure in the bottle B and the pressure in the reservoir 20 and the like. As a result, the flow of the liquid contained in the bottle B and the introduction of the deterioration suppressing gas into the bottle B continue. After that, when the liquid level of the liquid stored in the container 40 reaches the same height as the lower end portion 37 of the lower inner cylinder portion 33, the deterioration suppressing gas cannot pass through the inside of the lower inner cylinder portion 33. The introduction of the deterioration suppressing gas into the bottle B is stopped, and the flow of the liquid contained in the bottle B is stopped. That is, in the liquid extraction device 1, in the storage operation, the flow of the liquid contained in the bottle B can be automatically stopped without returning the operation arm 91 to the neutral position.

In the extraction operation performed after the storage operation, the deterioration suppressing gas is supplied into the connected portion 10 and the storage device 20, and the liquid stored in the container 40 of the storage device 20 is allowed to flow down to the extractor 50, such as a glass. It is an operation to extract to the outside of. As shown in FIG. 8, the extraction operation is performed in a state where the operation arm 91 is rotated downward from the neutral position. When the operating arm 91 rotates below the neutral position, the rotation pin 93 moves the upper flange 84 and the lower flange 85 below the neutral position. Therefore, the introduction pipe 53 and the extraction pipe 54 held by the holder 81 move below the neutral position, and the operating rod 75 moves below the neutral position. When the operating rod 75 moves downward from the neutral position, the valve body 71 of the second valve 70 moves downward, and the flow-down hole 44 and the communication hole 56 are opened to operate the second valve 70. At the same time, the first valve 60 remains inactive.

In the liquid extraction device 1 in such a state, in the extraction operation, the liquid stored in the container 40 of the reservoir 20 flows down due to the difference between the pressure in the reservoir 20 and the pressure in the extractor 50. It flows down the 44 and the communication hole 56. The liquid that has flowed down through the flow-down hole 44 and the communication hole 56 is introduced into the inside of the introduction pipe 53 from the introduction hole 58 through the space 57 in the cylinder 52. The liquid introduced into the introduction pipe 53 passes through the inside of the extraction pipe 54 and is extracted to the outside such as a glass. As described above, since the extraction operation is performed in a state where the inside of the reservoir 20 and the like is filled only with the liquid and the deterioration suppressing gas, the quality of the liquid stored in the container 40 is not deteriorated.

[Embodiment 1: Configuration of gas supply system]
As described above, the liquid extraction device 1 performs a plurality of operations such as an exhaust operation, a storage operation, and an extraction operation. In these operations, the liquid extraction device 1 supplies the deterioration suppressing gas from the gas supply system 120 into the reservoir 20 via the connected portion 10. At that time, the control unit 140 of the liquid extraction device 1 electrically sets each component of the gas supply system 120 so that the flow rate of the deterioration suppressing gas supplied into the reservoir 20 is different for each of these operations. Or it is controlled magnetically.

Specifically, in the control unit 140, the flow rate of the deterioration suppressing gas supplied into the reservoir 20 in the exhaust operation is larger than the flow rate of the deterioration suppressing gas supplied into the reservoir 20 in the extraction operation and the storage operation. Control to be. The flow rate of the deterioration suppressing gas during the storage operation and the flow rate of the deterioration suppressing gas during the extraction operation may be different, but the same flow rate is preferable because the configuration of the gas supply system 120 is simplified. Is.

In the present embodiment, the flow rate of the deterioration suppressing gas supplied into the reservoir 20 in the exhaust operation is also referred to as "first flow rate", and the flow rate of the deterioration suppressing gas supplied into the reservoir 20 in the extraction operation is referred to as "first flow rate". Also referred to as "second flow rate". The first flow rate is the flow rate of the deterioration suppressing gas that can quickly discharge the gas in the reservoir 20. The second flow rate is the flow rate of the deterioration-suppressing gas such that the liquid in the reservoir 20 does not scatter or foam and flows down quietly. If the liquid scatters or foams when it flows down, the scattered liquid may contaminate the glass or the like or the liquid extraction device 1, or the quality of the liquid may deteriorate, which is a problem.
