FIG. 3 shows an example of the appearance of the water server according to the embodiment. The configuration shown in FIG. 3 is an example, and the present invention is not limited to such a configuration. In FIG. 3, the same parts as in FIG. 1 are given the same reference numerals.
The water server 80 includes, for example, a housing 82 for housing the water supply function, the hot water supply function, and the control function part inside, and a cover part 84 capable of opening and closing a part on the front lower side of the water server 80. For example, an operation panel 72 for performing water supply / hot water supply operation, temperature setting operation, etc. is provided on the front upper side of the housing 82, and a predetermined range of the housing 82 is dented, and the ceiling side of the recessed portion A water supply / hot water supply unit 86 in which the water supply port 42 and the hot water supply port 52 are disposed is formed. Further, on the bottom side of the water supply / hot water supply unit 86, a mounting unit 88 for mounting a container (not shown) for receiving water supply or hot water supply is provided. For example, the placement unit 88 may have a drainage function for draining water or hot water that has not been received by a container or the like.

FIG. 4 shows an example of the internal configuration of the case.
The housing 82 is provided with a storage portion 90 inside the lid portion 84 for storing the raw water container 100 and other water intake means, the water supply pump 18, the water supply pipe 16, and the like. For example, the storage portion 90 may be in communication with the upper portion of the case where the cold water tank 20 or the hot water tank 24 is installed, or the upper portion of the case at or near the installation position of the lid 84 by a partition plate not shown. It may be cut off with the side.
The storage unit 90 stores the raw water container 100 for storing the raw water W therein. 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 surrounding the inner container 102 and having, for example, an octagonal side portion. Furthermore, the raw water cover 106 formed with the hard resin material which 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 directed upward. The raw water cover 106 is formed to surround part or all of the circumferential direction of the water supply portion 104.
When the raw water container 100 is stored, for example, in the storage unit 90, 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 of the storage unit 90 when, for example, the lid 84 is in an open state. Therefore, for example, when replacing the raw water container 100, the water server 80 takes out the raw water container 100 from the storage unit by pulling out the mounting table 108, and places the new raw water container 100 on the mounting table 108. The raw water container 100 may be carried to a predetermined position of the storage section 90 while being slid relative to the bottom of the housing 82.
Here, the predetermined position of the raw water container 100 set in the storage portion 90 is a position at which the water supply portion 104 of the raw water container can engage with the water intake portion 116 of the water server 80.

  Furthermore, the water intake portion 116 is, for example, a displacement mechanism portion 112 for approaching or separating the placed raw water container 100 or an exposed cover 118 which does not expose the water intake portion 116 toward at least the opening side of the storage portion 90. Prepare. 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 is protruded toward the opening side of the storage portion 90, for example.

<Configuration of Intake Unit 116>
FIG. 5 shows an example of the engagement state of the water intake portion 116 with the raw water container 100.
For example, a fixed length portion of the water intake portion 116 is inserted into the opening 119 of the water supply portion 104 from the distal end side. The water intake portion 116 has a hollow cylindrical shape, and the main body portion 120 engaged with the opening portion 119 and the projecting portion 121 disposed at the tip end side of the main body portion 120 and disposed in the raw water container 100. Equipped with The protruding portion 121 is an example of a means for inserting the water intake portion 116 into the opening 119 by pressing a sealing means (not shown) for sealing the opening 119 of the raw water container 100 before use, for example. This protrusion 121 may be provided with a water flow hole for taking in the raw water W, for example, at the tip portion.
For example, between the main body 120 and the protrusion 121, a single or a plurality of water intake holes 122 for taking in the raw water W are formed. The inside of the main body portion 120 may be provided with, for example, water passing portions 123 and 124 whose inner diameters are made different along the direction in which the raw water W taken in flows to the water supply pipe 16 side. Further, the water flow portion 124 is provided with a non-return portion 125 which does not allow the raw water W taken in to flow to the raw water container 100 side.
With such a configuration, the inside of the water supply pipe 16 becomes negative pressure by the operation of the water supply pump 18, whereby the stored raw water W flows into the main body 120 from the water intake hole 122 and flows into the water supply pipe 16 side. The inner container 102 of the container 100 contracts and the volume decreases.
In addition, the main body 120 is provided with a section 140 which protrudes a part of a portion not in contact with the raw water container 100 and is connected to the displacement mechanism 112.

<Displacement Mechanism 112>
FIG. 6 shows an example of the configuration of the displacement mechanism.
The displacement mechanism portion 112 includes, for example, a handle 114 formed in a rectangular shape having a long side and a short side, two arms 130 disposed so as to sandwich the central portion in the long side direction of the handle 114, and the arm 130 A support portion 132 disposed between the handle 114 and in contact with and supporting 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 disposed in the front-rear direction of the storage portion 90, whereas the long side of the arm 130 is disposed in the vertical direction of the storage portion 90. That is, the handle 114 and the arm 130 have a relationship of so-called twisting position. The support portion 132 connects the handle 114 and the arm 130. The arms 130 are provided with support frames 134 and 136 which are shaped to straddle the two arms 130 on the upper side and the lower side, for example, and which are fixed to the respective arms 134. The support frames 134 and 136 fix the spacing between the two arms 130 and integrate the handle 114 with the support portion 132 and the arms 130. Thus, the arm 130 follows the displacement caused by the operation of the handle 114 by the operator of the raw water container 100.
The displacement support part 112 is provided with the connection member 138 connected with the water intake part 116 which takes in the raw water W in the bottom part side. The connecting member 138 has, for example, a flat plate shape, and the bottom of the two-arm 130 is mounted and fixed on the upper surface side. Further, a part of the water intake portion 116 penetrates to a central portion of the connecting member 138, and a section 140 wider than the penetrating portion engages with the upper surface side of the connecting member 138. On the upper surface side of the connecting member 138, a locking piece 142 for locking to the section 140 is formed. At the central portion of the slice 140, a water flow portion is formed to flow the raw water W taken in by the water intake portion 116, and the water supply pipe 16 is connected to the water flow portion.

  Furthermore, the displacement mechanism portion 112 is provided with a guide portion 144 disposed substantially in parallel with the arm 130, for example, in the back surface direction of the storage portion 90. On the guide portion 144, for example, a support portion 146 installed at one end side of the handle 114 is installed. The support portion 146 engages with the guide portion 144 to support one end side of the handle 114 which receives an operation load.

For example, as shown in FIG. 7, when the lid 84 is in the open state, the displacement mechanism 112 pushes the end of the handle 114 disposed on the opening side of the storage unit 90 downward, thereby the arm 130. And the water intake section 116 is displaced downward via the connection member 138. As a result, the tip end portion of the water intake portion 116 protrudes below the exposed cover 118, and is inserted into the water supply portion 104 of the raw water container 100 disposed at a predetermined position.
At this time, for example, as shown in FIG. 8A, when the tip end side of the handle 114 is pushed down, the displacement mechanism part 112 is a lever with the tip part serving as a power point and a support part 146 fixedly supported by the guide part 144 as a fulcrum ( It becomes a lever. And the support part 132 becomes an action point, and the water intake part 116 is pushed down via the integrated arm 130. As shown in FIG.
In addition, in the storage unit 90, for example, a placement unit 150 for fixing and supporting the displacement mechanism unit 112 or a support arm 152 placed on the placement unit 150 and having the guide unit 144 erected via the support unit 154. Equipped with In addition, on the upper side of the storage unit 90, for example, a stopper piece 156 for limiting 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 side of the arm 130, and is slidably engaged with the tip side of the support arm 152. The support arm 152 includes, for example, a bifurcated arm 162 in which a portion close to the arm 130 is bifurcated. The branch arms 162 are formed in accordance with the number of arms 130. The bifurcated arm 162 is provided with an engagement surface portion 164 parallel to the back side of the arm 130 and a carriage 166 engaged with the rail 160. The rail 160 slides relative to the carriage 166 when the arm 130 is displaced downward in conjunction with the depressing operation of the handle 114. Thus, the arm 130 can be vertically displaced by the support arm 152, the bifurcated arm 162, and the engagement surface portion 164.
The amount of projection of the water intake portion 116 is proportional to the amount of operation of the handle 114. For example, the displacement mechanism unit 112 displays a display unit indicating the amount of operation around the handle 114 so that the water intake unit 114 protrudes to a position necessary for water intake, that is, sufficiently inserted into the water supply unit 104. You may provide.

In addition, as shown in FIG. 9, for example, when performing replacement processing of the raw water container 100, the displacement mechanism unit 112 pushes the end of the handle 114 disposed on the opening side of the storage unit 90 upward, The water intake portion 116 is displaced upward through 130 and the coupling member 138. Thus, the tip end portion of the water intake portion 116 is pulled out of the water supply portion 104, and the connection state is released. Further, the water intake portion 116 is disposed on the back side of the exposed cover 118 by pulling up the handle 114 to a necessary amount, and is not exposed at least from the opening of the storage portion 90 with the lid 84 opened.
At this time, for example, as shown in A of FIG. 10, when the tip end side of the handle 114 is pushed up, the support portion 146 fixedly supported by the guide portion 144 serves as a fulcrum and the support portion 132 serves as an action point. The lever pushes up the arm 130 and the water intake portion 116. The amount of operation of the handle 114 is limited by the contact of the support frame 134 with the contact portion 158 provided on the stopper piece 156. In this manner, by operating until the operation amount of the handle 114 is limited, the water intake portion 116 can be displaced to a position where it is covered in the exposed cover 118.
The rail 160 slides relative to the carriage 166 when the arm 130 is displaced upward interlockingly with the push-up operation of the handle 114 as shown in FIG. 10B, for example. Thereby, the arm 130 is vertically displaced by the support arm 152, the branch arm 162 and the engagement surface portion 164. By displacing the arm 130 through the rail 160, it is possible to prevent the displacement in the front-rear direction with respect to the operation of the handle 114. Further, by providing the rail mechanism, even if the worker or the raw water container 8 contacts the arm 130 etc. at the time of replacement work, the installation position of the arm 130 can be fixed by the support arm 152, the branch arm 162 and the engagement surface portion 164. The displacement of the upper and lower positions of the water intake portion 116 can be prevented.
In addition, the displacement mechanism portion 112 may be provided with a display portion indicating the pulling-up position of the handle 114 so as not to cause, for example, insufficient operation of the handle 114.

  The configuration shown in FIGS. 6 to 10 is an example. The displacement mechanism unit 112 is not limited as long as the worker replacing the raw water container 100 is caused to displace the height of the water intake portion 116 without touching the water intake portion 116 or the peripheral portion of the water intake portion 116. It may be As described above, in order to realize the purpose of preventing adhesion of bacteria to the water intake portion 116 and foreign matter mixing from the water supply portion, the displacement mechanism portion 112 is at least operated by the operator and operated to such operation means. Accordingly, a power or mechanism for operating the water intake portion 116 and a structure that supports the water intake portion 116 and is operated by such power or mechanism are provided.
