[0008] Hereinafter, preferred embodiments will be described with reference to the drawings. The same or equivalent components, members, and processes shown in each drawing are denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. Further, the embodiments are illustrative and not restrictive of the invention, and not all of the features and combinations thereof described in the embodiments are necessarily essential to the invention. Also, in this specification, "upper", "lower", "left", and "right" are respectively the upper, lower, left, and right as viewed from the user who uses the water discharge device, and "front" and "rear" are respectively the front side and the back side as viewed from the user.

[0009] Referring to FIG. 1, the water discharge device 12 is installed in, for example, a kitchen. The water discharge device 12 includes a water discharge device main body 16 provided with a water discharge part 28, a first water supply line 18 and a second water supply line 20 for supplying water to the water discharge part 28, and a control device 22. The first water supply line 18 and the second water supply line 20 are not particularly limited, but supply different types of water to the water discharge part 28 of the water discharge device 12. In the present embodiment, the first water supply line 18 supplies raw water (hot and cold mixed water) to the water discharge part 28, and the second water supply line 20 supplies reformed water to the water discharge part 28.

[0010] The water discharge device main body 16 includes a water discharge pipe part 26, a water discharge part 28, a first operation part 30, and a second operation part 32. The water discharge pipe part 26 is not particularly limited, but has a so-called gooseneck shape. In the present embodiment, the water discharge part 28 is provided at the tip of the water discharge pipe part 26. The water discharge part 28 discharges the water supplied from the first and second water supply lines 18 and 20 according to operations on the first and second operation parts 30 and 32.

[0011] The first water supply line 18 includes a water flow path 36 through which raw water (normal temperature water) is supplied from a water supply source 34 such as a water supply pipe, a hot water flow path 40 through which hot water is supplied from a hot water source 38 such as a water heater, a mixing valve 42 with a water stop function for mixing the normal temperature water supplied from the water flow path 36 and the hot water supplied from the hot water flow path 40, and a mixed water flow path 44 for supplying the hot and cold mixed water mixed by the mixing valve 42 to the water discharge part 28.

[0012] The mixing ratio of the normal temperature water and hot water in the mixing valve 42 and the flow rate of the mixed hot and cold water supplied from the mixing valve 42 (including the case where the flow rate is zero, i.e., the water supply is stopped) can be adjusted by operating the first operation unit 30 of the water discharge device main body 16. The first operation unit 30 is, for example, a single lever.

[0013] The second water supply line 20 includes a water supply passage 46, an on-off valve 54, a reforming unit 104, and a cooling unit 106. The water supply passage 46 is a flow passage that branches from the water flow passage 36 and leads to the water discharge part 28. The on-off valve 54, the reforming unit 104, and the cooling unit 106 are all provided on the water supply passage 46 and are arranged in this order from the upstream side.

[0014] The on-off valve 54 is an automatic on-off valve such as a solenoid valve or an electric valve. The on-off valve 54 opens and closes according to the instruction of the control device 22. In the present embodiment, the on-off valve 54 is provided on the upstream side of the reforming unit 104. The on-off valve 54 may be provided on the downstream side of the reforming unit 104, for example, between the reforming unit 104 and the cooling unit 106.

[0015] The reforming unit 104 includes a reforming cartridge 48, an additive liquid holding part 58, a liquid feeding part 60, and a sterilizing part 62.

[0016] The reforming cartridge 48 is a container-shaped cartridge that reforms the raw water passing through its interior. Hereinafter, the water reformed by the reforming cartridge 48 is referred to as reformed water. "Raw water" refers to the water to be reformed by the reforming cartridge 48. "Reforming" refers to removing specific components from the raw water or adding them to the raw water through physical or chemical changes. For example, when the raw water is tap water, the reforming cartridge 48 may be a water purification cartridge that removes the chlorine component contained in the tap water, that is, reforms the tap water into purified water as reformed water. Reforming may also be adding beauty components, fragrance components, carbonic acid components, hydrogen components, etc. to the raw water.

[0017] The additive liquid holding part 58 holds the additive liquid. The configuration of the additive liquid holding part 58 is not particularly limited, and various containers, tanks, etc. can be adopted. The additive liquid is used for drinking, such as a beverage stock solution for dilution, a food additive concentrate, a seasoning liquid, etc. In addition, the additive liquid may be used for applications that come into contact with the human body, such as soap water, lotion, body oil, etc. The applications that come into contact with the human body include the beverage stock solution for dilution used for the aforementioned drinking.

[0018] The liquid feeding part 60 feeds the additive liquid. The liquid feeding part 60 feeds the additive liquid by discharging the additive liquid sucked from the additive liquid holding part 58 to the water supply flow path 46 side. The configuration of the liquid feeding part 60 is not particularly limited, and for example, it is a pump, a compressor, etc. The liquid feeding part 60 operates with a power supply in this embodiment, but it may also operate without a power supply. In this case, the liquid feeding part 60 may be, for example, a water flow driven type pump that is driven using the flow of water flowing through the water supply flow path 46.

[0019] The sterilization part 62 sterilizes the additive liquid sucked from the additive liquid holding part 58. The sterilization part 62 is configured using, for example, a hollow fiber membrane filter, a photocatalyst, ultraviolet rays, etc.

[0020] The additive liquid fed by the liquid feeding part 60 is added to the reformed water. Thereby, diluted water obtained by diluting the additive liquid with the reformed water is generated. That is, the reforming unit 104 supplies diluted water obtained by diluting the additive liquid with the reformed water.

[0021] The reforming unit 104 may not include the reforming cartridge 48. In this case, the additive liquid is added to the raw water. Thereby, diluted water obtained by diluting the additive liquid with the raw water is generated. That is, the reforming unit 104 supplies diluted water obtained by diluting the additive liquid with the raw water.

[0022] The reforming unit 104 may not include the additive liquid holding part 58, the liquid feeding part 60, and the sterilization part 62. In this case, the reforming unit 104 supplies reformed water.

[0023] The cooling unit 106 includes a cold water tank 52, a normal temperature water on-off valve 55_1 and a cold water on-off valve 55_2, and a power conversion unit 64. The water supply passage 46 branches into two passages, a normal temperature water passage 46a and a cold water passage 46b, within the cooling unit 106 and merges within the cooling unit 106.

[0024] The cold water tank 52 is provided in the cold water passage 46b. A temperature sensor 53 for detecting the temperature of the water in the cold water tank 52 and a cooler 56 for cooling the water in the cold water tank 52 are assembled to the cold water tank 52. The cooler 56 cools the water in the cold water tank 52 so that the temperature detected by the temperature sensor 53 becomes equal to or lower than a set temperature (for example, 3°C to 5°C) according to the control by the control device 22.

[0025] The on-off valves 55_1 and 55_2 are automatic on-off valves such as solenoid valves and motor-operated valves, similar to the on-off valve 54. The on-off valves 55_1 and 55_2 open and close according to the instruction of the control device 22. The normal temperature water on-off valve 55_1 is provided in the normal temperature water passage 46a. The on-off valve 55_2 is provided in the cold water passage 46b on the downstream side of the cold water tank 52. As will be described in detail later, when discharging normal temperature water, the normal temperature water on-off valve 55_1 is opened, and when discharging cold water, the cold water on-off valve 55_2 is opened.

[0026] Power is supplied to the power conversion unit 64 from a power supply unit 66. The power supply unit 66 may be, for example, an AC adapter connected to an outlet (commercial power supply). In this case, the power conversion unit 64 includes a DC-DC converter and steps down the DC power supplied from the AC adapter to DC power of a predetermined voltage.

[0027] The power supply unit 66 may be an outlet plug connected to an outlet (commercial power supply). In this case, the power conversion unit 64 includes an AC-DC converter and converts the AC power supplied from the power supply unit 66 into DC power. The power conversion unit may further include a DC-DC converter that steps down the output of the AC-DC converter.

[0028] In any case, the power conversion unit 64 supplies DC power to the temperature sensor 53 and the cooler 56. Also, the power conversion unit 64 supplies DC power to the control device 22.

[0029] The control device 22 comprehensively controls the water discharge device 12. As described above, power is supplied to the control device 22 from the cooling unit 106. However, the control device 22 can also receive power from the power supply unit 68, for example, an AC adapter connected to an outlet, without going through the cooling unit 106. As will be described in detail later, the control device 22 causes water to be discharged from the water discharge unit 28 or stops the water discharge from the water discharge unit 28 according to an instruction from the second operation unit 32.

[0030] The above is the basic configuration of the water discharge device 12.

[0031] Note that the water discharge device 12 can also be configured without the cooling unit 106. The case where the water discharge device 12 does not include the cooling unit 106 includes not only the case where an inexpensive model without the cooling unit 106 is selected, but also the case where the cooling unit 106 is temporarily removed due to failure or maintenance. In these cases, it is sufficient that DC power is supplied to the control device 22 from the power supply unit 68.

[0032] Refer to FIG. 2. Each block shown in FIG. 2 is realized by elements and circuits including a CPU (Central Processing Unit) and a memory as a hardware configuration, and is realized by a computer program or the like as a software configuration. Here, however, functional blocks realized by their cooperation are depicted. Therefore, it is understood by those skilled in the art referred to in this specification that these functional blocks can be realized in various forms by a combination of hardware and software.

[0033] The control device 22 includes an input unit 81, a control unit 82, and a storage unit 84. The control unit 82 executes various data processes. The storage unit 84 stores data that is referenced and / or updated by the control unit 82. The storage unit 84 is implemented by a memory or a storage device.

[0034] The input unit 81 receives an input for selecting one operation mode from a plurality of operation modes of the water discharge and stop control. The input unit 81 may be, for example, a DIP switch or a push switch. The operation modes selectable in the present embodiment are a "normal mode" and a "restricted mode". The "restricted mode" is an operation mode that should be selected when the water discharge device 12 does not include the cooling unit 106.

[0035] The control unit 82 includes an operation mode registration unit 90, a water discharge and stop instruction acquisition unit 92, and a water discharge and stop control unit 94. The storage unit 84 includes an operation mode storage unit 96. The components of the control unit 82 and the storage unit 84 show only the components of interest in the present embodiment.

[0036] The operation mode registration unit 90 stores the operation mode received by the input unit 81 in the operation mode storage unit 96.

[0037] The water discharge and stop instruction acquisition unit 92 acquires the water discharge and stop instruction output by the second operation unit 32. Here, in the present embodiment, the second operation unit 32 is a rotary handle that can be switched to a plurality of rotational positions, and outputs an instruction corresponding to the rotational position to the control device 22. The instructions selectable by the second operation unit 32 are a "normal temperature water discharge instruction" for discharging reformed water at normal temperature from the water discharge unit 28, a "cold water discharge instruction" for discharging reformed water cooled by cold water from the water discharge unit 28, and a "water stop instruction" for stopping the water discharge from the water discharge unit 28.

[0038] The water discharge and stop control unit 94 executes water discharge and stop control according to the selected operation mode, that is, the operation mode stored in the operation mode storage unit 96.

[0039] (In the normal mode) When the water discharge and stop control unit 94 receives the "normal temperature water discharge instruction" from the water discharge and stop instruction acquisition unit 92, it opens the on-off valve 54 and the normal temperature water on-off valve 55_1 (the cold water on-off valve 55_2 is in the closed state) to discharge normal temperature dilution water. When the water discharge and stop control unit 94 receives the "cold water discharge instruction" from the water discharge and stop instruction acquisition unit 92, it opens the on-off valve 54 and the cold water on-off valve 55_2 (the normal temperature water on-off valve 55_1 is in the closed state) to discharge cooled dilution water. When the water discharge and stop control unit 94 receives the "water stop instruction" from the water discharge and stop instruction acquisition unit 92, it closes all the on-off valves 54, 55_1, and 55_2 to stop the water discharge.

[0040] (In the restricted mode) When the water discharge and stop control unit 94 receives the "normal temperature water discharge instruction" from the water discharge and stop instruction acquisition unit 92, it opens the on-off valve 54 to discharge normal temperature dilution water. When the water discharge and stop control unit 94 receives the "cold water discharge instruction" from the water discharge and stop instruction acquisition unit 92, it ignores the instruction and does not discharge water. Note that the water discharge and stop control unit 94 may also open the on-off valve 54 to discharge normal temperature dilution water even when the water discharge and stop instruction acquisition unit 92 receives the "cold water discharge instruction". When the water discharge and stop control unit 94 receives the "water stop instruction" from the water discharge and stop instruction acquisition unit 92, it closes the on-off valve 54 to stop the water discharge.

[0041] Refer to FIGS. 3 and 4. The system kitchen 110 includes a water discharge device 12, a cabinet 112, a counter 114, and a sink 116. The counter 114 and the sink 116 are arranged above the cabinet 112. The water discharge pipe portion 26 of the water discharge device 12 is installed on the counter 114. The sink 116 receives the water discharged from the water discharge device 12. The sink 116 is concealed by a curtain plate 118.

[0042] The cabinet 112 has a storage space 120 below the sink 116 where items can be stored. A drawer 122 is slidably stored in the storage space 120. The front surface of the drawer 122 is substantially flush with the curtain plate 118 and constitutes the front surface of the cabinet 112. The cabinet 112 may be provided with a shelf plate (not shown).

[0043] The control device 22, the reforming unit 104, and the cooling unit 106 each have separate housings. In other words, it can also be considered that the control device 22, the reforming unit 104, and the cooling unit 106 are divided so as to have separate housings for each function.

[0044] The control device 22, the reforming unit 104, and the cooling unit 106 are arranged such that at least a part of at least one of them is located in the non-storage space 123, which is the space behind the curtain plate 118. That is, the plurality of functional units are arranged such that at least a part of at least one of them is located in the non-storage space 123.

[0045] In the examples of FIGS. 3 and 4, the control device 22 is arranged such that its entirety is located in the non-storage space 123, specifically in the space to the right of the sink 116.

[0046] In the examples of FIGS. 3 and 4, the reforming unit 104 is arranged such that a part of it is located in the non-storage space 123, specifically in the space behind the curtain plate 118 and below the sink 116. The reforming unit 104 is arranged at an upper part of the storage space 120, that is, at a position relatively far from the bottom plate of the drawer 122. In other words, the reforming unit 104 is arranged at a position that does not relatively interfere with the storage of the drawer 122. The reforming unit 104 is fixed to the inner wall 112a of the cabinet 112 via a mounting member 130, for example, as described later.

[0047] The entire reforming unit 104 may be arranged in the non-storage space 123. Also, the entire reforming unit 104 may be arranged in the storage space 120, for example, in the space on the left and right of the drain pipe 124 extending from the drain port 116a of the sink 116. In this case, the reforming unit 104 may be arranged vertically such that the reforming cartridge 48 extends in the vertical direction.

[0048] In the examples of FIGS. 3 and 4, the entire cooling unit 106 is disposed in the storage space 120. Specifically, the cooling unit 106 is arranged to be side by side with the drain pipe 124. The cabinet 112 of the present embodiment is a drawer type cabinet, and the cooling unit 106 is disposed in a space deeper than the front plate (not shown) of the drawer 112 when the drawer 122 is closed.

[0049] Refer to FIGS. 5 to 9. The reforming unit 104 further includes a housing 70 and a mounting member 130 for mounting the housing 70 to the inner wall 112a of the cabinet 112. The housing 70 includes a housing main body 72 and a cartridge holder 74 (see FIG. 7) for detachably holding the reforming cartridge. The housing main body 72 is not particularly limited, but is a substantially rectangular parallelepiped box. The cartridge holder 74 is fixed to the housing main body 72 within the housing main body 72. The housing main body 72 has an insertion / removal port 72g which is an opening corresponding to the cartridge holder 74.

[0050] The cartridge holder 74 includes a holder portion 76, an inflow portion 78a, and an outflow portion 78b. The holder portion 76 detachably holds a held portion (described later) of the reforming cartridge 48. The inflow portion 78a allows raw water to flow into the reforming cartridge 48 from the water supply passage 46. The outflow portion 78b allows the reformed water that has passed through the reforming cartridge 48 to flow out to the water supply passage 46. When the reforming cartridge 48 is mounted on the cartridge holder 74, a flow path is formed through which water flows in the order of the inflow portion 78a of the cartridge holder 74, the reforming cartridge 48, and the outflow portion 78b.

[0051] The reforming cartridge 48 has an elongated shape and includes a held portion 48a and a gripping portion 48b. The held portion 48a is located at one end (the rear end side in FIG. 7) in the longitudinal direction of the reforming cartridge 48. The gripping portion 48b is generally located on the other end side (the front end side in FIG. 7) in the longitudinal direction of the reforming cartridge 48. Note that other portions may be provided between the held portion 48a and the gripping portion 48b.

[0052] The held portion 48a is the portion held by the holder portion 76. In the present embodiment, a male thread (not shown) centered on the longitudinal direction of the reforming cartridge 48 is formed on the outer peripheral surface 48c of the held portion 48a. A female thread (not shown) corresponding to the male thread of the held portion 48a is formed on the peripheral surface 76b of the corresponding insertion hole 76a of the holder portion 76. By screwing the male thread of the held portion 48a into the female thread of the holder portion 76, the reforming cartridge 48 is held by the holder portion 76 and thus by the housing 70. In this case, by rotating the reforming cartridge 48, for example, clockwise, the reforming cartridge 48 can be attached to the housing 70. By rotating the reforming cartridge 48, for example, counterclockwise, the reforming cartridge 48 can be removed from the housing 70. Note that the holding structure in which the holder portion 76 holds the held portion 48a is not limited to the screw structure, and for example, a structure using a snap fit, magnetic force, or the like may be used.

[0053] The gripping portion 48b is the portion that protrudes from the housing 70 when the reforming cartridge 48 is held by the housing 70. When replacing the reforming cartridge 48 or the like, the gripping portion 48b may be gripped to attach and detach the reforming cartridge 48.

[0054] Next, the attachment member 130 will be described. Hereinafter, for convenience, the attachment member 130 will be described using the notations of the up-down, front-back, left-right directions, but such notations of directions do not limit the posture when the attachment member 130 attaches the housing 70 to the inner wall 112a. For example, as will be described later with reference to FIG. 10, the housing 70 may be attached to the inner wall 112a such that the longitudinal direction of the reforming cartridge 48 coincides with the up-down direction.

[0055] The attachment member 130 attaches the housing 70 to the inner wall 112a of the cabinet 112 (the left inner wall in the examples of FIGS. 5 to 9). The housing 70 is attached to the inner wall 112a such that the longitudinal direction of the reforming cartridge 48 coincides with the front-rear direction. The attachment member 130 supports the housing 70 in a cantilevered manner. Here, when the housing 70 is supported in a simply supported manner, specifically, for example, when further supporting the right side of the housing 70 in the examples of FIGS. 5 to 9, a support structure for supporting the right side is required, thereby wasting the storage space 120. In contrast, when the attachment member 130 supports the housing 70 in a cantilevered manner, such a support structure is unnecessary, and the waste consumption of the storage space 120 can be avoided.

[0056] The attachment member 130 includes a fixing portion 132 fixed to the inner wall 112a of the cabinet 112, a first support portion 134 and a second support portion 136 that are vertically spaced apart from each other and extend in the left-right direction from the fixing portion 132, and an abutting portion 138 that extends in the left-right direction from the fixing portion 132 on the rear side of the front end portions of the first support portion 134 and the second support portion 136 and at least a part of which is located between the two support portions 134 and 136 in a front view (viewed in the front-rear direction from the front).

[0057] The fixing portion 132, the two support portions 134 and 136, and the abutting portion 138 are all plate-shaped in the examples of FIGS. 5 to 9. The fixing portion 132 has a rectangular plate shape. One or more insertion holes (through holes) 132a are formed in the fixing portion 132. The fixing portion 132 is fixed to the inner wall 112a of the cabinet 112 by a fastener 140 such as a screw that passes through the insertion hole 132a. Note that the fixing portion 132 may be fixed to the inner wall 112a by a double-sided tape or the like. In this case, the insertion hole 132a is unnecessary.

[0058] The first support portion 134 extends rightward from the lower end of the fixing portion 132. The first support portion 134 has a first support surface 134a facing upward (i.e., the normal line extends in the vertical direction). The second support portion 136 has a second support surface 136a facing the first support surface 134a in the vertical direction (i.e., facing downward). The first support surface 134a abuts against the lower surface 72a of the housing body 72, and the second support surface 136a abuts against the upper surface 72b of the housing body 72.

[0059] The first support portion 134 is fixed to the lower surface 72a of the housing body 72 by a fastening member such as a screw (not shown) that passes through the insertion hole 134b. Thereby, the housing 70 is supported from below by the first support portion 134. In addition to or instead of the first support portion 134, the second support portion 136 may be fixed to the upper surface 72b of the housing body 72 by a fastening member such as a screw. Thereby, the housing 70 is supported from above by the second support portion 136.

[0060] Here, as in the examples of FIGS. 5 to 9, when the first support surface 134a is relatively small and the first support surface 134a cannot support directly below the center of gravity of the housing 70, if the hand is released from the housing 70 before fixing the first support portion 134 with a screw or the like, the housing 70 will fall from the first support portion 134. On the other hand, by the second support surface abutting against the upper surface of the housing (i.e., pressing the upper surface), the fall of the modification unit 104 can be suppressed. Therefore, if the housing 70 is sandwiched between the first support surface 134a and the second support surface 136a, the hand can be released from the housing 70 and the first support portion 134 can be fixed to the lower surface 72a of the housing body 72 with both hands. That is, workability is improved.

[0061] The abutting portion 138 extends rightward from the rear end of the fixing portion 132. The abutting portion 138 has an abutting surface 138a facing forward. The rear surface 72c of the housing body 72 abuts against the abutting surface 138a. The abutting portion 138 has a fitting hole 138b into which a protrusion 72d formed on the rear surface 72c fits. The fitting hole 138b and the protrusion 72d have complementary shapes, in other words corresponding shapes, and further in other words substantially the same shape, when viewed in the front-rear direction from the rear. In the example of FIG. 6, the fitting hole 138b and the protrusion 72d are vertically long. By fitting the protrusion 72d into the fitting hole 138b, it is possible to prevent the reforming unit 104 from falling when the first support surface 134a cannot support directly below the center of gravity of the reforming unit. The abutting portion 138 may have a plurality of fitting holes 138b, the rear surface 72c may have a plurality of protrusions 72d, and the plurality of protrusions 72d may fit into the plurality of fitting holes 138b.

[0062] When installing the reforming unit 104, first, the mounting member 130 is fixed to the inner wall 112a of the cabinet 112. Next, the housing 70 is inserted from the front between the two support portions 134 and 136 and slid to abut against the abutting portion 138. At this time, when the left side surface 72e of the housing body 72 is slid along the fixing portion 132 to abut against the abutting portion 138, in other words, when the housing body 72 is slid with the left side surface 72e of the housing body 72 abutting against the fixing portion 132 to abut against the abutting portion 138, the protrusion 72d fits into the fitting hole 138b. Here, sliding the left side surface 72e of the housing body 72 along the fixing portion 132 means that when the fixing portion 132 is fixed to the inner wall 112a by a fastening tool 140 such as a screw, sliding the left side surface 72e along the fastening tool 140, that is, sliding with the left side surface 72e abutting against the fastening tool 140. The distance in the left-right direction from the fastening tool 140 or the fixing portion 132 to the fitting hole 138b and the distance in the left-right direction from the left side surface 72e of the housing body 72 to the protrusion 72d are substantially the same, whereby the easy fitting as described above is realized. Note that when installing the reforming unit 104, the reforming cartridge 48 may or may not be installed.

[0063] The housing body 72 has a surrounding wall 72f that surrounds the gripping portion 48b of the reforming cartridge 48. The surrounding wall 72f has a portion in the circumferential direction that is open, in other words, notched. In the example of FIG. 5, the portion of the surrounding wall 72f that faces downward, that is, the portion that faces the bottom plate 112 (see FIGS. 3 and 4) of the cabinet 112 via the drawer 122, is open. In other words, the portion of the surrounding wall 72f that is located below the gripping portion 48b of the mounted reforming cartridge 48 is open. Hereinafter, the open portion of the surrounding wall 72f will also be referred to as the open portion 72h. The width W in the left-right direction of the open portion 72h is preferably larger than the dimension S in the width direction (the direction orthogonal to the longitudinal direction) of the reforming cartridge 48. Since the surrounding wall 72f has the open portion 72h, when removing the reforming cartridge 48, when the held portion 48a of the reforming cartridge 48 comes out of the holder portion 76, the reforming cartridge 48 can be removed downward (i.e., in the direction of arrow D1 in FIG. 5) toward the open portion of the surrounding wall 72f. Also, when mounting the reforming cartridge 48, the reforming cartridge 48 can be inserted from below the open portion of the surrounding wall 72f toward the insertion / removal opening 72g (i.e., in the direction of arrow D2 in FIG. 5).

[0064] Here, when at least a part of the reforming unit 104 is arranged to be located in the non-accommodating space 123, if the reforming cartridge 48 can only be inserted and removed in the front-rear direction, the curtain plate 118 interferes and it is difficult to insert and remove the reforming cartridge 48. On the other hand, in the present embodiment, since the reforming cartridge 48 can be removed downward or inserted from below, interference with the curtain plate 118 can be avoided, and it is easy to insert and remove the reforming cartridge 48. That is, it is easy to replace the reforming cartridge 48.

[0065] The held portion 48a of the reforming cartridge 48 is entirely located on the anti-gripping portion side (i.e., the rear side) rather than at the center C (see FIG. 7) in the longitudinal direction of the reforming cartridge 48. In other words, in the longitudinal direction of the reforming cartridge 48, the held portion 48a is shorter than the gripping portion 48b. Stated yet another way, the range of the held portion 48a in the longitudinal direction of the reforming cartridge 48 is shorter than the length from one end (the rear end in FIG. 7) in the longitudinal direction of the reforming cartridge 48 to the center C in the longitudinal direction of the reforming cartridge 48. Since it is necessary to insert and remove the reforming cartridge 48 in the front-rear direction until the held portion 48a comes out of the holder portion 76, and the distance is short, the insertion and removal of the reforming cartridge 48 becomes easy.

[0066] In FIGS. 5 to 9, the case where the reforming unit 104 is attached to the left inner wall 112a has been described, but it is not limited thereto. For example, the reforming unit 104 may be attached to the right inner wall 112a. In the present embodiment, the same attachment member 130 can hold the right side of the housing 70 and be attached to the right inner wall 112a. In this case, the attachment member 130 may be turned upside down and the fixing portion 132 may be fixed to the right inner wall. Further, as shown in FIG. 6, the back surface 72c also has a protruding portion 72d on the right side, and this protruding portion 72d on the right side may be fitted into the fitting hole 138b.

[0067] Refer to FIG. 10. In the example of FIG. 10, the housing 70 is attached to the inner wall 112a such that the longitudinal direction of the reforming cartridge 48 coincides with the vertical direction. Specifically, the attachment member 130 is fixed to the right inner wall 112a (not shown) such that the first support portion 134 and the second support portion 136 face each other in the front-rear direction. The housing 70 is supported by the attachment member 130 such that the open portion 72h of the surrounding wall 72f faces forward.

[0068] Subsequently, the effects achieved by the present embodiment will be described.

[0069] If the control device 22, the reforming unit 104, and the cooling unit 106 are, for example, an integrated device (one housing), the device will naturally become larger, so there may be a problem that the device will interfere with the movement of the drawer unless it is a dedicated cabinet, that is, the device can only be installed in a dedicated cabinet. On the other hand, according to the present embodiment, the control device 22, the reforming unit 104, and the cooling unit 106 have separate housings from each other. In other words, the control device 22, the reforming unit 104, and the cooling unit 106 are divided so as to have separate housings from each other. In this case, the control device 22, the reforming unit 104, and the cooling unit 106 are naturally smaller than when they are integrated (one housing). Therefore, as an example, as shown in FIGS. 3 and 4, at least a part of the control device 22 and the reforming unit 104 can be arranged in the non-storage space 123. That is, according to the present embodiment, by dividing each functional unit so as to have a separate housing, each functional unit can be made smaller. As a result, in various cabinets, it is possible to arrange at least a part of at least one functional unit in the non-storage space 123. Thereby, in various cabinets, each functional unit can be arranged so as not to interfere with the movement of the drawer. From the above, according to the present embodiment, a water discharge device 12 that can be installed in various cabinets can be provided. As a result, it is not necessary to prepare a dedicated cabinet for installing the water discharge device 12.

[0070] According to the present embodiment, power is supplied from the cooling unit 106 to the control device 22. That is, power is supplied from one functional unit connected to an outlet to another functional unit. In this case, it is not necessary to connect each functional unit to an outlet, and one outlet is sufficient. Therefore, the water discharge device 12 can be used even in a cabinet where outlets are not abundant. That is, according to the present embodiment, a water discharge device 12 that can be installed in various cabinets can be provided.

[0071] According to the present embodiment, since the control device 22 can receive power from an AC adapter connected to an outlet without going through the cooling unit 106, for example, even when the cooling unit 106 is temporarily not provided due to a failure, the control device 22 and thus the water discharge device 12 can be used.

[0072] According to the present embodiment, the reforming unit 104 can be fixed to the inner wall 112a so as not to interfere with the storage in the storage space 120. Further, the reforming unit 104 can be installed at a position where the reforming cartridge 48 can be easily replaced. Further, since a part of the circumferential direction of the surrounding wall 72f of the housing 70 is open, the reforming cartridge 48 can be removed obliquely toward the open portion 72h. Further, the reforming cartridge 48 can be inserted obliquely from the open portion 72h. Thereby, for example, when at least a part of the reforming unit 104 is arranged so as to be located in the non-storage space 123 which is the space behind the curtain plate 118, the reforming cartridge 48 can be inserted and removed so as not to interfere with the curtain plate 118. That is, the storage space 120 can be effectively used, and a user-friendly water discharge device 12 can be realized. Also, the inner wall 112a of the cabinet 112

[0073] According to the present embodiment, the reforming unit 104 includes a mounting member 130, and the support portion of the mounting member 130 supports the housing 70 from below, and the protrusion 72d of the housing 70 fits into the fitting hole 138b of the contact portion 138. Thereby, the mounting member 130 can support the housing 70 so that the housing 70 does not fall from the support portion even when the support portion cannot support the center of gravity of the housing 70 directly below. Therefore, the hands can be released from the housing 70 and the support portion can be fixed to the lower surface 72a of the housing body 72 with both hands.

[0074] According to the present embodiment, the housing 70 and the mounting member 130 are configured such that when the housing 70 is slid on the fixing portion 132 and brought into contact with the contact portion 138, the protrusion 72d fits into the fitting hole 138b. Thereby, fine positioning of the housing 70 is not required, and the construction becomes easy.
