[0012] A drinking water dispenser 1 according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a drinking water dispenser 1 according to an embodiment. The drinking water dispenser 1 is a device that stores tap water and dispenses (supplies) it in response to a user's operation. The drinking water dispenser 1 has a detachable drinking water container 50, and is used by attaching the drinking water container 50 filled with tap water. The drinking water dispenser 1 purifies tap water stored in a drinking water container 50, adjusts the temperature, and then dispenses drinking water W from a water supply unit 3.

[0013] The drinking water container 50 is a resin container that stores tap water (drinking water W) and is housed (mounted) inside the floor-standing server body 2 (see Figures 10 and 11). The tap water stored in the drinking water container 50 is sucked in by a pump, passes through a water purification filter, and is sent to the inside of the drinking water dispenser 1 as drinking water W.

[0014] The drinking water dispenser 1 is equipped with a cold water tank for storing cold water and a hot water tank for storing hot water (neither is shown). Drinking water W supplied from a drinking water container 50 is sent to the cold water tank and the hot water tank. The cold water tank and the hot water tank are each covered with a heat insulating material and housed in the upper part of the interior of the server main body 2. A compressor (not shown) for cooling the drinking water W is housed in the lower part of the interior of the server main body 2.

[0015] The water supply unit 3 is a space where the user receives drinking water W, and is located at the top front of the server body 2. A water outlet 4 that dispenses drinking water W (cold water, hot water, room temperature water) is provided at the top of the water supply unit 3. Drinking water W sent from the cold water tank and hot water tank is dispensed from the water outlet 4. An operation panel 5 is provided above the water supply unit 3 (on the front top surface of the server body 2) for users to perform various operations. This operation panel 5 is provided with a cold water dispense button, a hot water dispense button, a room temperature water dispense button, a heat sterilization button, etc.

[0016] FIG. 2 is a side view (partial cross-sectional view) showing the drinking water dispenser 1 according to the embodiment. FIG. 3 is an exploded perspective enlarged view showing the server main body 2 with the liquid atomizing cassette 20 removed. FIG. 4 is an exploded perspective view showing the liquid atomizing cassette 20. As shown in FIG. FIG. 5 is a cross-sectional view showing the liquid atomizing cassette 20. As shown in FIG.

[0017] In addition to the water supply function described above, the drinking water dispenser 1 has a spray humidification function. The drinking water dispenser 1 is equipped with a liquid atomization cassette 20 and a liquid container 60, and can spray atomized liquid V to humidify the room in which the drinking water dispenser 1 is placed.

[0018] The liquid atomization cassette 20 is mounted on the top of the server main body 2. A top cover 41 is disposed on the rear top surface of the server main body 2. A spray nozzle cover 45 of the liquid atomization cassette 20 is exposed on this top cover 41. An operation panel 42 for the liquid atomization cassette 20 is also provided on the top cover 41. The liquid atomization cassette 20 is detachably mounted to the server main body 2. When the top cover 41 is removed from the server main body 2, the liquid atomization cassette 20 is exposed. This makes the liquid atomization cassette 20 detachable from the server main body 2.

[0019] The server body 2 has an upper surface 2a formed with a concave liquid atomization cassette housing portion 6 for housing the liquid atomization cassette 20 therein. A water outlet 7 is provided on the bottom surface of the liquid nebulization cassette storage section 6. The water outlet 7 discharges the liquid V toward the liquid nebulization cassette 20. An electrical contact section 8 is provided on the side surface of the liquid nebulization cassette storage section 6. The electrical contact section 8 is electrically connected to the liquid nebulization cassette 20 to supply power and send and receive various signals.

[0020] The liquid atomization cassette 20 atomizes a liquid V, such as hypochlorous acid water or tap water, and sprays it forward from the top of the server main body 2. The liquid V stored in a liquid container 60 is supplied (fed) to the liquid atomization cassette 20. The liquid container 60 is a resin container that stores the liquid V, and is housed (mounted) inside the floor-standing server main body 2. The liquid V stored in the liquid container 60 is sucked by a pump and sent to the liquid atomization cassette 20 from the water outlet 7 of the liquid atomization cassette storage section 6.

[0021] The liquid atomizing cassette 20 includes a cassette body 21, a first support member 31, a second support member 32, a sub-tank 35, and a spray nozzle cover 45. The cassette body 21 is provided with a fan 25 and a vibrator 28, and atomizes and sprays the liquid V.

[0022] An electrical contact portion 22 is provided on the side surface of the cassette body 21. The electrical contact portion 22 comes into contact (electrically connects) with the electrical contact portion 8 of the liquid atomization cassette housing portion 6. An operation panel 23 is provided on the top surface of the cassette body 21. The operation panel 23 overlaps with the operation panel 42 when the cassette body 21 (liquid nebulization cassette 20) is covered with the top cover 41. The operation panel 42 and the operation panel 23 function together as an operation display unit for the liquid nebulization cassette 20. An upper cover switch 24 is further provided on the upper surface of the cassette body 21. The upper cover switch 24 connects and disconnects the power circuit (power wiring) of the liquid atomization cassette 20 in response to the attachment and detachment of the upper cover 41. The top cover switch 24 detects whether the cassette body 21 (liquid atomization cassette 20) is covered with the top cover 41. When a magnet provided on the back surface of the top cover 41 approaches the top cover switch 24, the top cover switch 24 turns ON (connected). Detection information (detection result) of the top cover switch 24 is sent to the control unit of the cassette body 21.

[0023] Inside the cassette body 21, a fan 25, a duct 26, and an atomization chamber 27 are formed. The fan 25 generates wind to spray the atomized liquid V. The duct 26 is a cavity that sends the wind generated by the fan 25 toward the atomization chamber 27. The atomization chamber 27 is a space that communicates with the duct 26 and is filled with the atomized liquid V. The atomization chamber 27 has openings at the top and bottom, and the atomized liquid V is introduced from below and sprayed out from above toward the outside.

[0024] A vibrator 28 and a water level sensor 29 are provided on the bottom surface of the cassette body 21. The vibrator 28 is disposed below the atomization chamber 27. The vibrator 28 and the cassette body 21 are coupled (electrically connected) via an electric cable (not shown). The vibrator 28 applies ultrasonic vibrations to the liquid V to atomize the liquid V. The atomized liquid V flows toward the atomization chamber 27. The water level sensor 29 protrudes downward from the bottom surface of the cassette body 21. The water level sensor 29 detects the water level of the liquid V stored below the cassette body 21 (in the sub-tank 35) in multiple stages (for example, two stages: an upper limit and a lower limit).

[0025] A first support member 31, a second support member 32 and a sub-tank 35 are detachably attached to the lower part of the cassette body 21. The first support member 31 is a member that supports the vibrator 28. The vibrator 28 is attached to the bottom surface of the first support member 31. The first support member 31 positions the vibrator 28 below the atomization chamber 27. The second support member 32 is a member disposed on the bottom surface of the first support member 31 and covers the outer periphery of the vibrator 28. The second support member 32 functions as a windbreak wall that prevents the wind from the fan 25 from flowing below the atomization chamber 27 (near the vibrator 28).

[0026] The subtank 35 is an opaque bathtub-shaped member that covers the entire lower surface of the cassette body 21. The subtank 35 accommodates the vibrator 28, the water level sensor 29, the first support member 31, and the second support member 32, and further stores the liquid V. The liquid V stored in the subtank 35 also flows into the first support member 31 and the second support member 32. The water level sensor 29 is almost immersed in the liquid V, and the vibrator 28 is completely immersed in the liquid V.

[0027] A valved water inlet 36 is provided at the bottom of the sub-tank 35. The valved water inlet 36 is in close contact with the water outlet 7 of the liquid nebulization cassette housing 6. This allows the liquid V sent from the liquid container 60 to enter only the sub-tank 35 without flowing into the liquid nebulization cassette housing 6.

[0028] A spray nozzle cover 45 is attached above the atomization chamber 27. A spray nozzle 46 is formed in the spray nozzle cover 45. A spray nozzle sub-cover (not shown) that guides the spray direction of the liquid V is attached to the back surface of the spray nozzle cover 45 near the spray nozzle 46.

[0029] As described above, the liquid atomization cassette 20 atomizes the liquid V, such as hypochlorous acid water or tap water, and sprays the atomized liquid V from the spray nozzle 46 on the top surface of the drinking water dispenser 1. The liquid atomization cassette 20 can be operated via the operation panel 23 by pressing the operation panel 42 located near the spray nozzle 46. By operating the operation panel 42, for example, the amount of liquid V sprayed can be increased or decreased, or the liquid atomization cassette 20 can be stopped.

[0030] The liquid atomization cassette 20 drives the fan 25 to send air toward the atomization chamber 27 via the duct 26. At the same time, the vibrator 28 is driven to atomize the liquid V stored in the sub-tank 35 and send it to the atomization chamber 27. The mist (liquid V) present in the atomization chamber 27 is then carried by the air from the fan 25 and sprayed out from the spray nozzle 46 toward the front side of the server main body 2.

[0031] The water level sensor 29 detects the water level of the liquid V stored in the subtank 35. The measurement information of the water level sensor 29 is sent to the control unit of the server main body 2. The server main body 2 feeds the liquid V from the liquid container 60 toward the liquid atomization cassette 20 based on the detection result of the water level sensor 29. Specifically, when the water level of the liquid V stored in the subtank 35 falls below a predetermined position (lower limit), the server main body 2 supplies (feeds) the liquid V from the liquid container 60 toward the subtank 35. Furthermore, when the water level of the liquid V stored in the subtank 35 rises above a predetermined position (upper limit), the server main body 2 stops supplying the liquid V to the subtank 35.

[0032] A human presence sensor 9 is disposed on the front surface of the server main body 2 (directly above the water supply unit 3). Measurement information from the human presence sensor 9 is sent to the control unit of the server main body 2. The human presence sensor 9 detects a user of the drinking water dispenser 1. The human presence sensor 9 detects a user standing in front of the drinking water dispenser 1 and attempting to receive water. The server main body 2 drives the liquid atomization cassette 20 (fan 25, vibrator 28) based on the detection result of the human sensor 9. Specifically, when the human sensor 9 detects a user, the server main body 2 stops the liquid atomization cassette 20. In other words, it stops spraying the liquid V from the spray nozzle 46. This prevents the user from being directly exposed to the liquid V sprayed from the spray nozzle 46. On the other hand, when the human sensor 9 does not detect a user, the server main body 2 continues to operate the liquid atomization cassette 20 without stopping it. When the user moves away from the drinking water dispenser 1, the liquid atomization cassette 20 resumes spraying the liquid V from the spray nozzle 46. Because the user has moved away from the drinking water dispenser 1, they will not be directly exposed to the liquid V sprayed from the spray nozzle 46.

[0033] When performing maintenance on the liquid atomization cassette 20, the top cover 41 on the top of the server main body 2 must be removed. The top cover switch 24 of the liquid atomization cassette 20 detects that the top cover 41 has been removed. The top cover switch 24 turns OFF (shutoff). When the top cover switch 24 becomes inactive, the drinking water dispenser 1 stops supplying power to the liquid atomization cassette 20. This allows the liquid nebulization cassette 20 to be safely attached and detached to and from the server main body 2. In other words, it is possible to prevent the liquid V from being supplied from the server main body 2 to the liquid nebulization cassette storage section 6 (liquid nebulization cassette 20) during maintenance, which could cause overflows, etc. Furthermore, it is possible to prevent the risk of electric shock when attaching and detaching the liquid nebulization cassette 20.

[0034] FIG. 6 is a perspective view showing the first drawer section 16 in the drawn out state. FIG. 7 is a perspective view showing the state in which the liquid container 60 has been removed from the first drawer section 16. As shown in FIG.

[0035] A liquid container housing section 15 is provided on the front side of the lower vertical section of the server body 2. The liquid container housing section 15 (first drawer section 16) is disposed directly below the drinking water container housing section 11, which will be described later. A liquid container 60 is removably disposed in the liquid container housing section 15. Liquid container storage section 15 is an opening formed in the lower front portion of server body 2, and includes first drawer section 16 into which liquid container 60 is attached. The first drawer section 16 is a tray body having a bottom plate section on which the drinking water container 50 is placed and a front plate section that stands in front of the bottom plate section. When the user grasps the upper end of the front plate section, the first drawer section 16 can be slid back and forth. Between the bottom surface of the liquid container storage section 15 and the lower surface of the bottom plate of the first drawer section 16, a pair of slide rails (not shown) are laid in parallel along the front-rear direction.

[0036] A connecting part 17 having a water inlet is provided on the bottom plate part of the first drawer part 16. The connecting part 17 has a shape that allows the bottom part (lower surface 60b) of the liquid container 60 to fit into it. When the liquid container 60 is placed on the connecting part 17 of the bottom plate part, the water outlet provided on the lower surface 60b of the liquid container 60 and the water inlet of the connecting part 17 fit together. This allows the connecting part 17 to receive the liquid V from the liquid container 60.

[0037] The front panel of first drawer 16 becomes one with the front surface of server body 2 when first drawer 16 is pulled into server body 2. The front panel is a decorative panel that closes liquid container storage section 15 that opens at the front surface of server body 2. A handle is provided on the side of the front panel to allow the user to grasp the drawer.

[0038] The second drawer section 12 is open on both sides and the rear. That is, the first drawer section 16 does not have side surfaces extending from the sides of the bottom plate section or a rear surface extending from the rear. The reason why there are no side surfaces is to prevent liquid container 60 from interfering with first drawer part 16 when liquid container 60 is attached to or detached from bottom plate part (connecting part 17). It is sufficient that both sides (side plates) of first drawer section 16 are partially open. When attaching or detaching liquid container 60 to or from bottom plate section (connecting section 17), it is sufficient that the user's hands (both hands) do not interfere with first drawer section 16.

[0039] FIG. 8 is a perspective view showing the liquid container 60. As shown in FIG. FIG. 9 is a perspective view showing a state in which liquid inlet 63 of liquid container 60 is open.

[0040] Liquid container 60 is a rectangular, opaque box (cuboid) molded from, for example, polypropylene. Liquid container 60 consists of a container body with an open top and a lid that covers the opening. The container body and lid are welded together without any gaps and are fixed so that they cannot be removed. Liquid container 60 is formed in a pyramidal shape with an outer shape that gradually decreases downward. Liquid container 60 has a liquid inlet 63 on its upper surface 60a, and a valved water outlet on its lower surface 60b. The reason why the liquid container 60 is opaque is that when hypochlorous acid water is stored as the liquid V, it needs to have a light-blocking property.

[0041] The outer dimensions (maximum dimensions) of liquid container 60 are a width in the horizontal (left-right) direction of approximately 20 cm, a depth in the vertical (front-to-back) direction of approximately 20 cm, and a height in the up-down direction of approximately 22 cm. In other words, liquid container 60 has a shape in which the length in the front-to-back direction (depth) is shorter than the length in the left-to-right direction (width). Liquid container 60 can contain approximately 4 to 5 L of liquid V, such as tap water or hypochlorous acid water. When liquid container 60 is filled with water, its weight will be approximately 4 to 5 kg.

[0042] Of the side surfaces of the liquid container 60, a pair of lateral side surfaces 60s facing left and right are each formed with a handle 65 for a user to grip (hold) the liquid container 60 with both hands. The handle 65 has a shape in which the upper end side of the lateral side surface 60s protrudes like a canopy. Specifically, the handle 65 protrudes from the upper end of the liquid container 60 by about 1 to 2 cm. By placing both hands (four fingers excluding the thumbs) on the handles 65, the user can stably grasp (hold) the liquid container 60 and lift or lower it.

[0043] FIG. 10 is a perspective view showing the second drawer section 12 in the drawn out state. FIG. 11 is a perspective view showing the second drawer section 12 with the drinking water container 50 removed.

[0044] A drinking water container housing section 11 is provided on the front side of the center in the vertical direction of the server body 2. The drinking water container housing section 11 (second drawer section 12) is arranged directly below the water supply section 3. A drinking water container 50 is detachably arranged in the drinking water container housing section 11. The drinking water container storage section 11 is an opening formed in the front of the server body 2, and includes a second drawer section 12 into which a drinking water container 50 is attached.

[0045] The second drawer 12 has substantially the same structure as the first drawer 16. The drinking water container 50 has the same structure as the liquid container 60. The second drawer section 12 is a tray body having a bottom plate section on which the drinking water container 50 is placed and a front plate section that stands in front of the bottom plate section. When the user grasps the upper end of the front plate section, the second drawer section 12 can be slid back and forth. Between the bottom surface of the drinking water container housing section 11 and the lower surface of the bottom plate of the second drawer section 12, a pair of slide rails (not shown) are laid in parallel along the front-rear direction.

[0046] A connecting part 13 having a water inlet is provided on the bottom plate part of the second drawer part 12. The connecting part 13 has a shape that allows the bottom of the drinking water container 50 to fit into it. When the drinking water container 50 is placed on the connecting part 13 of the bottom plate part, the water outlet provided on the underside of the drinking water container 50 fits into the water inlet of the connecting part 13. This allows the connecting part 13 to receive drinking water W from the drinking water container 50. A water purification filter 14 is also detachably attached to the bottom plate portion. The water purification filter 14 purifies the drinking water W received from the drinking water container 50. The drinking water W that has passed through the water purification filter 14 is sent to a cold water tank or the like.

[0047] The front panel of the second drawer section 12 becomes one with the front surface of the server body 2 when the second drawer section 12 is pulled into the interior of the server body 2. The front panel is a decorative panel that closes the drinking water container storage section 11 that opens at the front surface of the server body 2. A handle is provided at the top of the front surface of the front panel so that the user can grasp the second drawer section 12.

[0048] The second drawer section 12 is open on both sides and the rear, i.e., the second drawer section 12 does not have side surfaces extending from the sides of the bottom plate section or a rear surface extending from the rear. The reason why there are no side surfaces is to prevent the drinking water container 50 from interfering with the second drawer part 12 when the drinking water container 50 is attached to or detached from the connecting part 13, as will be described later. It is sufficient that both sides (side plates) of the second drawer section 12 are partially open. When attaching or detaching the drinking water container 50 to or from the connecting section 13, the user's hands (both hands) do not interfere with the second drawer section 12.

[0049] The drinking water container 50 is a rectangular transparent box (cuboid) molded from, for example, polypropylene. The drinking water container 50 consists of a container body with an open top and a lid that covers the opening. The container body and the lid are welded together without any gaps and are fixed so that they cannot be removed. The drinking water container 50 is formed in a pyramidal shape with its outer shape gradually decreasing downwards. A drinking water inlet 53 is provided on the top surface of the drinking water container 50, and a water outlet with a valve is provided on the bottom surface.

[0050] The outer dimensions (maximum dimensions) of the drinking water container 50 are approximately 20 cm in width in the horizontal (left-right) direction, approximately 15 cm in depth in the vertical (front-to-back) direction, and approximately 25 cm in height in the up-down direction. In other words, the drinking water container 50 has a shape in which the length in the front-to-back direction (depth) is shorter than the length in the left-to-right direction (width). The drinking water container 50 can hold approximately 4 to 5 L of tap water (drinking water W). When the drinking water container 50 is filled with water, its weight is approximately 4 to 5 kg.

[0051] Of the side surfaces of the drinking water container 50, a pair of lateral side surfaces facing left and right are each formed with a handle 55 for a user to grasp (hold) the drinking water container 50 with both hands. The handle 55 has a shape in which the upper end side of the lateral surface protrudes like a canopy. Specifically, the handle 55 protrudes from the upper end of the drinking water container 50 by about 1 to 2 cm. By placing both hands (four fingers excluding the thumb) on the handles 55, the user can stably grasp (hold) the drinking water container 50 and lift or lower it.

[0052] In this way, the drinking water dispenser 1 has a water supply function and a spray function, and can achieve efficient operation of these functions. The liquid nebulization cassette 20 is detachably attached to the server main body 2, allowing for efficient maintenance of the liquid nebulization cassette 20. The top cover switch 24 of the liquid nebulization cassette 20 disconnects the power circuit of the liquid nebulization cassette 20 in response to the attachment and detachment of the top cover 41, preventing electric shock during maintenance. The spray time can be easily extended because the liquid V is sent from the liquid container 60 toward the liquid atomization cassette 20. The liquid atomization cassette 20 has a detachable sub-tank 35, allowing for efficient maintenance. When the human sensor 9 of the server main body 2 detects a user, the atomization of the liquid V is stopped, so that the user can be prevented from being directly exposed to the liquid V. Since the server main body 2 is provided with the first drawer section 16 for accommodating the liquid container 60 inside the server main body 2, the burden of attaching and detaching the liquid container 60 can be reduced.
