You may cut the edge with the side.
The storage unit 90 stores the raw water container 100 that stores the raw water W inside. The raw water container 100 includes an inner container 102 made of vinyl or synthetic resin in which the raw water W is sealed, and a raw water case 103 that surrounds the inner container 102 and has, for example, an octagonal side surface portion. Further, a raw water cover 106 made of a hard resin material that covers the upper side of the raw water case 103 is provided. The inner container 102 is provided with, for example, a water supply unit 104 for discharging the raw water W toward the upper side. The raw water cover 106 is formed so as to surround a part or all of the water supply portion 104 in the peripheral surface direction.
Further, when the raw water container 100 is stored in the storage unit 90, for example, the bottom surface of the raw water case is placed on the mounting table 108. The mounting table 108 can be taken in and out from the storage portion 90, for example, when the lid portion 84 is in the open state. Therefore, for example, when the raw water container 100 is replaced, the water server 80 takes out the raw water container 100 from the storage unit by pulling out the loading table 108, and when a new raw water container 100 is installed, the water server 80 is placed on the loading table 108. The raw water container 100 may be carried to a predetermined position of the storage portion 90 while sliding with respect to the bottom portion of the housing 82.
Here, the predetermined position of the raw water container 100 set in the storage unit 90 is a position where the water supply unit 104 of the raw water container can engage with the water intake unit 116 of the water server 80.

Be prepared. The displacement mechanism portion 112 is an example of a means for displacing the height of the water intake portion 116 in response to the operation of the handle 114 of the lever whose tip portion protrudes toward the opening side of the storage portion 90, for example.

<Structure of water intake unit 116>
FIG. 5 shows an example of the engagement state of the water intake unit 116 with the raw water container 100.
For example, a portion having a certain length from the tip end side of the water intake portion 116 is inserted into the opening 119 of the water supply portion 104. The water intake portion 116 has a hollow tubular shape, and has a main body portion 120 that is engaged with the opening 119 and a protruding portion 121 that is installed on the tip side of the main body portion 120 and is arranged in the raw water container 100. To be equipped. The protruding portion 121 is an example of a means for inserting the water intake portion 116 into the opening 119 by pressing, for example, a sealing means (not shown) that seals the opening 119 of the raw water container 100 before use. The protruding portion 121 may be provided with a water passage hole for taking in raw water W at the tip portion, for example.
In the water intake portion 116, for example, one or a plurality of intake holes 122 for taking in raw water W are formed between the main body portion 120 and the protruding portion 121. The inside of the main body 120 may include, for example, water passage portions 123 and 124 having different inner diameters along the direction in which the taken-in raw water W flows toward the water supply pipe 16. Further, the water passage portion 124 is provided with a check portion 125 that does not allow the taken-in raw water W to flow to the raw water container 100 side.
With such a configuration, the inside of the water supply pipe 16 becomes negative pressure due to the operation of the water supply pump 18, so that the stored raw water W flows into the main body 120 from the intake hole 122 and flows into the water supply pipe 16 side, and the raw water flows. The inner container 102 of the container 100 contracts to reduce the volume.
In addition, the main body 120 includes an intercept 140 that projects a part of the portion that does not come into contact with the raw water container 100 and connects to the displacement mechanism 112.

<Displacement mechanism 112>
FIG. 6 shows a configuration example of the displacement mechanism unit.
The displacement mechanism portion 112 includes, for example, a handle 114 formed in a square shape having a long side and a short side, two arms 130 arranged so as to sandwich the central portion of the handle 114 in the long side direction, and the arm 130. A support portion 132 that is arranged between the handles 114 and supports them in contact with them is provided. The arm 130 is, for example, a square having a long side and a short side. In the displacement mechanism portion 112, the long side of the handle 114 is arranged in the front-rear direction of the storage portion 90, whereas the long side of the arm 130 is arranged in the vertical direction of the storage portion 90. That is, the handle 114 and the arm 130 have a so-called twisted position relationship. The support portion 132 connects the handle 114 and the arm 130. The arm 130 includes support frames 134 and 136 that are shaped to straddle the two arms 130, for example, on the upper side and the lower side surface side, and are fixed to each arm 134. The support frame bodies 134 and 136 fix the arrangement interval of the two arms 130, and integrate the handle 114, the support portion 132, and the arm 130. As a result, the arm 130 follows the displacement caused by the operation of the handle 114 by the replacement operator of the raw water container 100.
The displacement support portion 112 includes a connecting member 138 on the bottom side that connects with the intake portion 116 that takes in the raw water W. The connecting member 138 has, for example, a flat plate shape, and the bottom portion of the two arms 130 is placed and fixed on the upper surface side. Further, a part of the water intake portion 116 penetrates the central portion of the connecting member 138, and a section 140 wider than the penetrating portion is engaged with the upper surface side of the connecting member 138. A locking piece 142 that locks to the section 140 is formed on the upper surface side of the connecting member 138. A water passage portion for flowing the raw water W taken in by the water intake portion 116 is formed in the central portion of the section 140, and the water supply pipe 16 is connected to this water passage portion.

Further, the displacement mechanism portion 112 includes a guide portion 144 arranged substantially parallel to the arm 130, for example, in the back direction of the storage portion 90. A support portion 146 installed on one end side of the handle 114 is installed on the guide portion 144, for example. By engaging with the guide portion 144, the support portion 146 supports one end side of the handle 114 that receives a load due to the operation.

As shown in FIG. 7, for example, when the lid portion 84 is opened, the displacement mechanism portion 112 pushes down the end portion of the handle 114 arranged on the opening side of the storage portion 90, thereby pushing the end portion of the handle 114 downward to the arm 130. And the intake portion 116 is displaced downward via the connecting member 138. As a result, the tip portion of the water intake portion 116 projects downward from the exposed cover 118 and is inserted into the water supply portion 104 of the raw water container 100 arranged at a predetermined position.
At this time, as shown in A of FIG. 8, for example, when the tip end side of the handle 114 is pushed down, the displacement mechanism portion 112 has a lever (a lever (support point 146) fixedly supported by the guide portion 144 as a fulcrum. (Lever). Then, the support portion 132 serves as an action point, and the water intake portion 116 is pushed down via the integrated arm 130.
In addition, in the storage portion 90, for example, a mounting portion 150 for fixing and supporting the displacement mechanism portion 112 or a support arm 152 mounted on the mounting portion 150 and having a guide portion 144 erected via the support portion 154. To be equipped. Further, on the upper side of the storage portion 90, for example, a stopper piece 156 that limits the upward displacement of the handle 114 and a contact portion 158 may be provided.
Further, as shown in FIG. 8B, for example, the displacement mechanism portion 112 includes a rail 160 on the back surface side of the arm 130, and is slidably engaged with the tip end side of the support arm 152. The support arm 152 includes, for example, a branch arm 162 in which a portion close to the arm 130 side is branched into two. The branch arms 162 are formed according to the number of arms 130. The branch arm 162 includes an engaging surface portion 164 parallel to the back surface side of the arm 130, and a carriage 166 that engages with the rail 160. When the arm 130 is displaced downward in conjunction with the push-down operation of the handle 114, the rail 160 slides with respect to the carriage 166. As a result, the arm 130 can be displaced in the vertical direction by the support arm 152, the branch arm 162, and the engaging surface portion 164.
The amount of protrusion of the water intake unit 116 is proportional to the amount of operation of the handle 114. The displacement mechanism unit 112 has a display unit indicating the amount of operation around the handle 114 so that, for example, the water intake unit 114 projects to a position required for water intake, that is, it is sufficiently inserted into the water supply unit 104.

The water intake portion 116 is displaced upward via the 130 and the connecting member 138. As a result, the tip portion of the water intake unit 116 is pulled out from the water supply unit 104, and the connected state is released. Further, the water intake portion 116 is arranged on the back side of the exposed cover 118 by pulling up the handle 114 to a required amount, and is not exposed at least from the opening portion of the storage portion 90 in which the lid portion 84 is opened.
At this time, as shown in A of FIG. 10, for example, when the tip end side of the handle 114 is pushed up, the displacement mechanism portion 112 has the support portion 146 fixedly supported by the guide portion 144 as a fulcrum and the support portion 132 as an action point. The lever pushes up the arm 130 and the intake portion 116. The amount of operation of the handle 114 is limited by the support frame 134 coming into contact with the contact portion 158 installed on the stopper piece 156. By operating the handle 114 until the amount of operation is limited in this way, the water intake portion 116 can be displaced to a position where it is covered in the exposed cover 118.
When the arm 130 is displaced upward in conjunction with the push-up operation of the handle 114, for example, as shown in B of FIG. 10, the rail 160 slides with respect to the carriage 166. As a result, the arm 130 is displaced in the vertical direction by the support arm 152, the branch arm 162, and the engaging surface portion 164. By displacing the arm 130 through the rail 160, it is possible to prevent the arm 130 from being displaced in the front-rear direction with respect to the operation of the handle 114. Further, by providing the rail mechanism, even if an operator or a raw water container 8 or the like comes into contact with the arm 130 or the like during replacement work, the installation position of the arm 130 can be fixed by the support arm 152, the branch arm 162 and the engaging surface portion 164. , It is possible to prevent the vertical position of the water intake portion 116 from being displaced.
In addition, the displacement mechanism unit 112 may be provided with a display unit indicating the pulling position of the handle 114 so as not to cause insufficient operation of the handle 114, for example.

The configuration shown in FIGS. 6 to 10 is an example. The displacement mechanism unit 112 has any configuration as long as it allows the operator who replaces the raw water container 100 to displace the height of the water intake unit 116 without touching the water intake unit 116 or the peripheral portion of the water intake unit 116. It may be.
