The Y direction is the width direction of the drinking water supply device 1 of the present embodiment. The Z direction is the vertical direction of the drinking water supply device 1 of the present embodiment. In the Z direction, the Z1 direction is the upward direction and the Z2 direction is the downward direction. The X direction, the Y direction, and the Z direction are orthogonal to each other. The vertical direction is, in principle, the vertical direction, but is not limited to this.

The room temperature water tank 10 is a container that is formed in a cylindrical shape and stores the room temperature water W. Room temperature is the temperature of the environment in which the drinking water supply device 1 is installed, and is, for example, the room temperature when the drinking water supply device 1 is installed indoors. The room-temperature water tank 10 of the present embodiment is detachably configured as, for example, a replacement water supply container, and is arranged above the drinking water supply device 1. The room temperature water tank 10 is placed in the container receiver 15 of the drinking water supply device 1 in a state where the room temperature water W is filled therein. The drinking water supply device 1 has a pipe 20 that connects the room temperature water tank 10 and the cold water tank 11 to each other. The pipe 20 is a water passage that connects the room temperature water tank 10 and the cold water tank 11 to each other and sends the room temperature water W from the room temperature water tank 10 to the cold water tank 11. The room temperature water W in the room temperature water tank 10 flows into the cold water tank 11 through the pipe 20. The pipe 20 may be provided with a water stop valve (not shown) that automatically (or manually) stops the flow of the room temperature water W in the pipe 20.

The cold water tank 11 is a container that cools the room temperature water W supplied from the room temperature water tank 10 and stores it as cold water CW. The cold water tank 11 of the present embodiment is arranged, for example, in an intermediate portion between the upper side and the lower side of the drinking water supply device 1. The cold water tank 11 is formed in a cylindrical shape, and stores the room temperature water W flowing from the opening 11a at the upper end in the internal space 110 and discharges it from the water outlet 22a at the lower end. The opening 11a is closed by a lid portion (not shown) having a through hole when the cold water tank 11 is accommodated in the drinking water supply device 1. The pipe 20 is inserted into the through hole provided in the lid portion. The internal space 110 communicates with the room temperature water tank 10 via the pipe of the pipe 20. The cold water tank 11 is covered with a heat insulating material, etc., and has a heat insulating structure so as not to let cold air escape. As shown in FIGS. 2 and 3, the cold water tank 11 has a partition plate 111 that is fixed to the inner bottom surface of the cold water tank 11 and that is located midway in the vertical direction of the internal space 110. When the partition plate 111 is attached to the cold water tank 11, a gap (hereinafter, also simply referred to as “gap”) is formed between the outer peripheral surface and the inner peripheral surface of the cold water tank 11, and the room temperature is passed through the gap. The water W flows from the upper direction of the partition plate 111 to the lower direction. In the internal space 110 of the cold water tank 11, the partition plate 111 is divided into a normal temperature water layer in which the normal temperature water W stays and a cold water layer in which the cold water CW stays. The room-temperature water layer is formed upward from the partition plate 111, and the cold water layer is formed downward from the partition plate 111. The normal temperature water layer and the cold water layer communicate with each other through the gap. When the room temperature water W is supplied from the room temperature water tank 10 to the cold water tank 11, the partition plate 111 cools the cool water CW accumulated in the lower part of the cool water tank 11 by the cooler 13 and cools the room temperature water tank 10 from the room temperature water tank 10. It is prevented from being stirred by the normal temperature water W supplied into the inside 11.

The partition plate 111 is formed in a circular shape and has a plate-shaped portion 112 having an outer diameter (or outer circumference) smaller than the inner diameter (or inner circumference) of the cold water tank 11 and a plate-shaped portion extending to the inner bottom surface of the cold water tank 11. And a support portion 113 that supports the portion 112. The plate-shaped portion 112 has four convex portions 115 protruding from the outer peripheral surface and formed at intervals in the circumferential direction. The plate-shaped portion 112 of the present embodiment has a pair of convex portions 115 that project outward from the outer peripheral surface and that face each other in the first direction P with the center O of the plate-shaped portion 112 interposed therebetween. The center O is the center in the horizontal direction of the plate-shaped portion 112, as shown in FIG. The first direction P is, for example, a direction inclined by approximately 45° clockwise with respect to the width direction (Y direction) when the partition plate 111 is viewed from the Z1 direction (directly above direction). The plate-shaped portion 112 further includes a pair of convex portions 115 that project outward from the outer peripheral surface and that face each other in the second direction Q that is orthogonal to the first direction P with the center O of the plate-shaped portion 112 interposed therebetween. Have. The four convex portions 115 are formed at regular intervals along the outer peripheral surface of the plate-shaped portion 112. The height of the convex portion 115 is set in consideration of ease of assembling the partition plate 111 to the cold water tank 11. For example, as shown in FIG. 5, the convex portion 115 has a height that does not contact the inner peripheral surface of the cold water tank 11 when the partition plate 111 is attached to the cold water tank 11. In other words, the outer diameter of the outer circumference provided with the pair of convex portions 115 is set to be larger than the outer diameter of the conventional plate-shaped portion and smaller than the inner diameter of the cold water tank 11.

The support portion 113 has a recess 114 communicating with the opening 114a provided in the plate-like portion 112, storing the room temperature water W flowing from the opening 114a, and discharging the water from the through holes 117 and 118 in the downward direction (Z2 direction). .. The opening 114a is formed in an elliptical shape and has a major axis in the depth direction and a minor axis in the width direction. The through holes 117 and 118 are formed on the inner bottom surface of the recess 114 at intervals in the depth direction. The support portion 113 is fixed to the end portions of the two pipes 21 and 24 which penetrate the bottom surface of the cold water tank 11 and are inserted into the through holes 117 and 118 and communicate with the space portion 116 in the recess 114. In the through hole 117, the pipe 21 for sending the room temperature water W staying in the room temperature water layer to the water outlet 40 is inserted while the partition plate 111 is attached to the cold water tank 11. A pipe 24 for sending the room temperature water W staying in the room temperature water layer to the warm water tank 12 is inserted into the through hole 118 with the partition plate 111 attached to the cold water tank 11. The pipe 24 is a water channel that connects the cold water tank 11 and the hot water tank 12 and sends the room temperature water W from the cold water tank 11 to the hot water tank 12.

The cold water tank 11 is provided with, for example, a water level sensor (not shown) that detects the water level of the room temperature water W accumulated in the cold water tank 11. When the water level detected by the water level sensor decreases, the room temperature water W is supplied from the room temperature water tank 10 to the cold water tank 11 in accordance with the decrease in the water level. The cold water tank 11 is provided with a drain D for discharging the cold water CW accumulated inside to the outside. By opening the drain D, the cold water CW accumulated in the cold water tank 11 can be drained.

The warm water tank 12 is a container that is formed in a cylindrical shape, heats the room temperature water W supplied from the room temperature water tank 10, and stores it as warm water HW. The hot water tank 12 has a heat insulating structure so as not to release heat to the outside. The hot water tank 12 is arranged, for example, below the drinking water supply device 1. The drinking water supply device 1 has a pipe 24 that connects the cold water tank 11 and the hot water tank 12 to each other. The room temperature water W in the cold water tank 11 flows into the hot water tank 12 through the pipe 24. Like the cold water tank 11, the hot water tank 12 is provided with a drain D. By opening the drain D, the warm water HW stored in the warm water tank 12 can be drained.

The cooler 13 lowers the temperature of the room temperature water W by exchanging heat with the room temperature water W retained in the cold water tank 11, and is arranged along the outer peripheral surface of the cold water tank 11. The cooler 13 is configured to cool the room temperature water W retained below the partition plate 111. The cooler 13 is electrically connected to a control unit (not shown), and the normal temperature water W in the cold water tank 11 is set to a preset cold water temperature (a temperature lower than the temperature of the normal temperature water) according to an instruction from the control unit. By lowering the temperature to CW, the temperature of the cold water CW is maintained at the cold water temperature, that is, the room temperature water W is driven as the cold water CW.

The heater 14 raises the temperature of the room temperature water W by exchanging heat with the room temperature water W retained in the warm water tank 12, and is arranged inside the warm water tank 12. The heater 14 keeps the hot water HW stored in the hot water tank 12 at a high temperature. The heater 14 is electrically connected to a control unit (not shown), and the normal temperature water W in the hot water tank 12 is set to a preset hot water temperature (a temperature higher than the temperature of the normal temperature water) according to an instruction from the control unit. The temperature of the warm water HW is maintained at the warm water temperature, that is, the room temperature water W is driven as the warm water HW.

The pipe 21 is a water passage that connects the cold water tank 11 and the water outlet 40 and sends the room temperature water W from the cold water tank 11 to the water outlet 40. In the cold water tank 11, the pipe 21 guides the room temperature water W staying upward from the partition plate 111 to the water outlet 40. A solenoid valve 31 is arranged in the middle of the pipe 21.

The pipe 22 is a water passage that communicates the cold water tank 11 and the water outlet 40 at a position different from the pipe 21 and sends cold water from the cold water tank 11 to the water outlet 40. The pipe 22 guides the cold water CW staying downward from the partition plate 111 to the water outlet 40 in the cold water tank 11. A solenoid valve 32 is arranged in the middle of the pipe 22.

The pipe 23 is a water channel that communicates with the hot water tank 12 and the water outlet 40 and sends hot water from the hot water tank 12 to the water outlet 40. The pipe 23 guides the hot water HW stored in the hot water tank 12 to the water outlet 40. A solenoid valve 33 is arranged in the middle of the pipe 23.

The solenoid valves 31-33 electrically open/close the corresponding pipes 21, 22, 23. Specifically, the solenoid valve 31 is arranged on the pipe 21 and opens and closes the pipe 21. The solenoid valve 32 is arranged on the pipe 22 and opens and closes the pipe 22. The solenoid valve 33 is arranged on the pipe 23 and opens and closes the pipe 23. The solenoid valves 31 to 33 mainly include a solenoid coil (not shown), an opening/closing valve, and a spring. In the non-energized state, the solenoid valves 31 to 33 urge the on-off valve downward by a spring to move the on-off valve to the closed position, and in the energized state, energize the solenoid coil from a power source (not shown). Magnetic flux is generated in the surroundings and drives the on-off valve upward to move it to the open position. The solenoid valves 31 to 33 transition from the non-energized state to the energized state in response to an operation signal from an operation unit (not shown), and drive the on-off valve to change the closed position to the open position.

Next, the assembling work of the partition plate 111 to the cold water tank 11 will be briefly described. First, the worker inserts the pipes 21 and 24 into the two through holes provided near the center of the inner bottom surface of the cold water tank 11. Next, the worker welds and fixes the pipes 21 and 24 to the outer bottom surface of the cold water tank 11 by using a welding jig. Next, the worker fits and attaches resin packings to the ends of the pipes 21 and 24 protruding from the inner bottom surface of the cold water tank 11. Next, the operator grips the two depressions provided on the upper surface of the plate-shaped portion 112, lowers the partition plate 111 from directly above the opening 11a of the cold water tank 11, and penetrates the bottom surface of the recess 114. The ends of the pipes 21 and 24 are fitted into the holes 117 and 118, and the partition plate 111 is pushed downward. In this way, the partition plate 111 is assembled to the cold water tank 11.

Conventionally, no protrusions were formed on the outer peripheral surface of the partition plate.Therefore, when assembling the partition plate, the operator confirms that the gap between the outer peripheral surface of the partition plate and the inner peripheral surface of the cold water tank is uneven. However, when there is a bias, work such as correction is performed. On the other hand, in the partition plate 111 of the present embodiment, the plate-shaped portion 112 has a plurality of convex portions 115 that project outward from the outer peripheral surface and are formed at intervals in the circumferential direction. With this, when the partition plate 111 is assembled, even if there is a deviation in each direction in which the convex portion 115 is provided, the convex portion 115 comes into contact with the inner peripheral surface of the cold water tank 11 to prevent the deviation in each direction. It can be suppressed. Moreover, even if there is a deviation in the direction in which the convex portion 115 is not provided, the two convex portions 115 that are adjacent to each other across the direction are in contact with the inner peripheral surface of the cold water tank 11 so that there is a deviation in that direction. Can be suppressed.

Next, an example of the water discharge operation of the cold water CW in the drinking water supply device 1 will be briefly described. In the drinking water supply device 1, the user operates an operation lever (not shown) of the operation unit to discharge any one of the room temperature water W, the cold water CW, and the hot water HW from the water outlet 40. For example, when the user operates the operation lever for cold water, an operation signal is transmitted from the operation unit to the solenoid valve 32. The solenoid valve 32 changes from the non-energized state to the energized state in response to an operation signal from the operation unit, and the open/close valve switches from the closed position to the open position. As a result, the pipe 21 and the water outlet 40 communicate with each other, and the cold water CW from the cold water layer in the cold water tank 11 passes through the pipe 21 and is discharged from the water outlet 40 via the junction X. When the operation lever is continuously operated, the electromagnetic valve 32 is maintained in the open state, so that the cold water CW is continuously discharged from the water outlet 40. In the cold water tank 11, the cold water CW is discharged from the cold water layer through the water outlet 22a to lower the water level, and the normal temperature water W flows from the normal temperature water layer to the cold water layer through the gap. The room temperature water W of the room temperature water layer mainly flows into the cold water layer from the gaps existing between the plurality of convex portions 115 formed on the outer peripheral surface of the plate-shaped portion 112. The room temperature water W flows along the inner peripheral surface of the cold water tank 11 cooled by the cooler 13 and is cooled by mixing the cold water CW in the cold water layer, and the temperature decreases and transitions to the cold water CW. When the operation of the operation lever is stopped, the electromagnetic valve 32 is switched from the open state to the closed state, and the cold water CW from the water outlet 40 is stopped.

As described above, the drinking water supply device 1 according to the present embodiment is formed in a cylindrical shape, stores the room temperature water W flowing from the opening 11a at the upper end in the internal space 110, and discharges the water from the water outlet 22a at the lower end. A cold water tank 11 is provided. Further, the drinking water supply device 1 is fixed to the cold water tank 11 and is arranged along the outer peripheral surface of the cold water tank 11 and a partition plate 111 that is located midway in the up-down direction of the internal space 110 and below the partition plate 111. And a cooler 13 for cooling the room temperature water W staying on the side. The partition plate 111 is formed in a circular shape, and has a plate-shaped portion 112 having an outer diameter (or outer circumference) smaller than the inner diameter (or inner circumference) of the cold water tank 11 and extends to the inner bottom surface of the cold water tank 11. The support portion 113 supports the shape portion 112. The plate-shaped portion 112 has a plurality of convex portions 115 that project outward from the outer peripheral surface and are formed at intervals in the circumferential direction. With the above configuration, the unevenness generated in the gap between the outer peripheral surface of the partition plate 111 and the inner peripheral surface of the cold water tank 11 is reduced, and the increase of the room temperature water W flowing to the cold water layer is suppressed. It is possible to suppress the temperature rise of the cold water. Specifically, when the partition plate 111 is assembled to the cold water tank 11, even if the gap between the outer peripheral surface of the partition plate 111 and the inner peripheral surface of the cold water tank 11 is uneven, the outer peripheral surface of the plate-shaped portion 112 is By contacting the convex portion 115 provided on the inner peripheral surface of the cold water tank 11, the deviation can be reduced. Further, in the plate-shaped portion 112, the outer diameter of the outer periphery where the pair of convex portions 115 is provided is larger than the outer diameter of the conventional plate-shaped portion, so the partition plate 111 is provided in each direction in which the convex portion 115 is provided. Even if is inclined, the convex portion 115 can contact the inner peripheral surface of the cold water tank 11 and suppress the inclination of the partition plate 111.

In addition, in the drinking water supply device 1 according to the present embodiment, the plurality of convex portions 115 project outward from the outer peripheral surface of the plate-shaped portion 112 and are orthogonal to each other across the center of the plate-shaped portion 112 (for example, the first It is formed in one direction P and second direction Q), respectively. Thereby, the deviation of the gap in the circumferential direction of the plate-shaped portion 112 can be efficiently reduced, and the above-described effect can be further achieved.

Further, in the drinking water supply device 1 according to the present embodiment, the partition plate 111 communicates with the opening 114a provided in the plate-shaped portion 112 in the support portion 113, and stores the room temperature water W flowing from the opening 114a. It has a concave portion 114 that discharges water from the downward through holes 117 and 118. The partition plate 111 is fixed to the ends of the two pipes 21 and 24 which penetrate the bottom surface of the cold water tank 11 and are inserted into the through holes 117 and 118 and communicate with the space 116 in the recess 114. When the partition plate 111 is fixed to the cold water tank 11 with the above-described configuration, a pair of plates are provided on the outer peripheral surface of the plate-shaped portion 112 so as to face the first direction P and/or the second direction Q with the center O of the plate-shaped portion 112 interposed therebetween. Alternatively, by forming the two pairs of convex portions 115, it is possible to efficiently reduce the bias of the gap.

[Modification]

For example, the plate-shaped portion 112 may have three convex portions 115 that project outward from the outer peripheral surface and are formed at intervals in the circumferential direction. In this case, it is preferable that the three convex portions 115 are formed, for example, at regular intervals (for example, a central angle of 120°) along the outer peripheral surface of the plate-shaped portion 112, but the present invention is not limited to this. Absent. Further, it is preferable that the convex portion 115 is provided on the outer periphery of the plate-shaped portion 112 in a direction in which the gap is likely to be biased. For example, when the partition plate 111 is likely to be biased in the direction orthogonal to the arrangement direction of the two pipes 21 and 24 to which the cold water tank 11 is fixed, the convex portion 115 is formed in the direction displaced from the arrangement direction. Preferably.

Further, in the above embodiment, the plurality of convex portions 115 are formed on the outer peripheral surface of the plate-shaped portion 112 of the partition plate 111, but the present invention is not limited to this. For example, the plurality of convex portions 115 may protrude inward from the inner peripheral surface of the cold water tank 11 that faces the outer peripheral surface of the plate-shaped portion 112, and may be formed at intervals in the circumferential direction. In this case, the plurality of convex portions 115 may be formed to face each other in the first direction P with the center of the inner circumference of the cold water tank 11 facing the outer peripheral surface of the plate-shaped portion 112 interposed therebetween. Furthermore, a plurality of convex portions 115 project inward from the inner peripheral surface of the cold water tank 11 facing the outer peripheral surface of the plate-shaped portion 112, and are orthogonal to each other with the center of the inner peripheral surface of the cold water tank 11 interposed therebetween (for example, the first It may be formed in each of the direction P and the second direction Q).
