Abstract

In the present invention, provided are the following: a water storage tank (10) having a water filling port (14) through which water is filled into the tank; a water feeding port (20) for feeding the water stored inside the water storage tank (10); and an ultraviolet light source unit that is disposed inside the water storage tank (10) and that sterilizes the water stored in the water storage tank (10) by irradiating the water with ultraviolet light.

Description

Water feeder and lid

The present invention relates to a water dispenser and a lid.

2. Description of the Related Art Conventionally, it has been practiced that tap water or the like distributed to homes is sterilized by ultraviolet light and then used as drinking water. This is because even if it is tap water, bacteria such as micrococci or E. coli may be mixed. In particular, in developing countries and the like, even tap water for household use may not be sufficiently disinfected, or bacteria may be mixed during water distribution.

As a water sterilizer that can be used even at home, after passing raw water from a tap through a filter, it is known that the flowing filtered water is irradiated with ultraviolet light to sterilize, and the water after sterilization is stored in a tank etc. (See, for example, Patent Document 1). A water supply port (faucet) is attached to the tank, and water can be supplied from the water supply port and used as potable water or water for cooking.

Japanese Patent Application Laid-Open No. 2005-211851

However, in the conventional water sterilizer described above, the filtered water (i.e., running water) is sterilized while passing through the filtration filter, so there is a problem that it takes time to store a desired amount of water after sterilization. Moreover, since the conventional water sterilizer irradiates an ultraviolet-ray with respect to the flowing water which flows through a water pipe, there also exists a problem of being stored in a tank, without fully disinfecting.

Then, an object of this invention is to provide the water supply which can fully disinfect a large amount of water in a short time, and the lid which can be attached or detached to the said water supply.

In order to achieve the above object, a water dispenser according to one aspect of the present invention includes a water storage tank portion having a water injection port portion for injecting water internally, and a water supply port for supplying water stored in the water storage tank portion. And an ultraviolet light source unit disposed inside the water storage tank and irradiating the water stored in the water storage tank with ultraviolet light to sterilize the water.

Moreover, a lid according to one aspect of the present invention is a lid that can be attached to and detached from a water supply device, and an ultraviolet light source unit is attached to the back surface of the lid. When it is attached to a vessel, the water stored in the water dispenser is irradiated with ultraviolet light to sterilize the water.

According to the present invention, a large amount of water can be sufficiently sterilized in a short period of time.

Embodiment
[Overview]
First, an overview of a water supply apparatus according to the present embodiment will be described using FIGS. 1 to 3.

FIG. 1 is a schematic perspective view of a water dispenser 1 according to the present embodiment. 2A to 2C are a front view, a top view and a right side view, respectively, of the water dispenser 1 according to the present embodiment. FIG. 3 is a cross-sectional view of the water dispenser 1 according to the present embodiment. Specifically, FIG. 3 shows a cross section taken along line III-III shown in FIG. 2B. Moreover, in each figure, let the left-right direction of the water dispenser 1 be an X-axis direction, let the front-back direction be a Y-axis direction, and let an up-down direction be Z-axis direction.

The water dispenser 1 which concerns on this Embodiment provides water (water supply), such as drinking water or water for cooking, for example. Specifically, the water supply device 1 sterilizes by irradiating ultraviolet light (UV light) to water such as tap water, well water, spring water, rain water (hereinafter referred to as "non-sterile water"). The water dispenser 1 provides the water after sterilization (hereinafter, described as “sterile water”) as potable water or the like.

As shown in FIG. 1, the water dispenser 1 according to the present embodiment is a small, lightweight, portable water dispenser that is called a so-called water jug. The water dispenser 1 may be installed at home, for example, or may be carried outdoors for use.

As shown in FIGS. 1 to 3, the water dispenser 1 includes a water storage tank 10, a water supply port 20, a lid 30, an ultraviolet light source 40, and an open / close sensor 50 (see FIGS. 4 and 5). , A drive circuit 60, an indicator 70, a speaker 80, and a handle 90.

Hereinafter, components included in the water dispenser 1 according to the present embodiment will be described in detail with reference to FIGS. 1 to 3 as appropriate.

[Water storage tank]
FIG. 4 is a schematic perspective view showing the water storage tank unit 10 according to the present embodiment.

As shown in FIG. 4, the water storage tank unit 10 is a container unit having a water injection port 14 for injecting water therein. In the water storage tank 10, non-sterile water is injected through the water injection port 14, and the non-sterile water injected is stored. The stored non-sterile water is irradiated with ultraviolet light by the ultraviolet light source unit 40 shown in FIG. 3 and the like, and then supplied (discharged) to the outside through the water supply port 20.

In the present embodiment, as shown in FIG. 4, the water storage tank portion 10 is a bottomed substantially cylindrical body having an opening and a bottom. Specifically, the water storage tank unit 10 has a double structure and can maintain the temperature of the water stored therein. More specifically, the water storage tank unit 10 includes an outer container 11 and an inner container 12.

The outer container 11 is a container forming an outer shell of the water storage tank unit 10.

The inner container 12 is a container in which water is stored. The volume of the inner container 12, ie, the volume of water stored in the water storage tank unit 10, is, for example, 6 liters to 10 liters, but is not limited thereto. The inner container 12 is smaller than the outer container 11 and disposed inside the outer container 11.

Each of the outer container 11 and the inner container 12 is a bottomed substantially cylindrical body having an opening and a bottom. The opening and the bottom may have the same size in plan view, or the opening may be smaller than the bottom (a so-called bottle shape). Further, the shape of each of the outer container 11 and the inner container 12 is not limited to this, and may be, for example, a bottomed rectangular cylinder.

As shown in FIG. 3, the opening of the outer container 11 and the opening of the inner container 12 are connected. Thus, a closed space 13 is formed between the outer container 11 and the inner container 12. The closed space 13 is a reduced pressure space such as a vacuum, for example. Thereby, heat conduction between the outer container 11 and the inner container 12 can be suppressed.

The water injection port 14 is an opening provided in the water storage tank 10. Specifically, the water injection port 14 is an opening of the inner container 12. Unsterilized water is injected into the inside of the inner container 12 through the water injection port 14.

The water injection port 14 is closed by a lid 30 as shown in FIG. The plan view shape (top view shape) of the water injection port 14 is substantially circular. Thus, the water injection port 14 can be closed by the lid 30 by rotating the lid 30 and screwing it on. However, not only screwing, but also a recess or a protrusion may be provided to engage with the water injection port 14 and the lid 30, respectively. For example, the recess may be fitted into the protrusion and the water inlet 14 may be closed by the lid 30. Also, there is no need to provide a locking mechanism, in particular, if it is merely closing.

A hole 15 to which the water supply port 20 is connected is formed in a side surface near the bottom of the water storage tank 10. The hole 15 communicates the outside of the outer container 11 with the inside of the inner container 12. Water (for example, sterile water) stored in the inner container 12 can be supplied to the outside through the hole 15 and the water supply port 20.

The inner surface of the water storage tank portion 10 is covered with metal. Specifically, the inner surface of the inner container 12 is covered with metal. For example, the inner container 12 and the outer container 11 are formed of a metal material. The metal material is, for example, stainless steel. In addition, the outer side container 11 and the inner side container 12 may be formed from not only a metal material but a resin material etc., for example. At this time, the inner surface of the inner container 12 may be covered with a metal material by plating, for example.

As shown in FIG. 4, an open / close sensor unit 50 (tank-side sensor 52) is provided in the vicinity of the water injection port 14 of the water storage tank unit 10. Specifically, the tank sensor 52 is provided at a position close to the lid sensor 51 provided on the lid 30 when the lid 30 is properly closed.

In addition, the water storage tank part 10 does not need to have a double structure as mentioned above.

[Water inlet]
The water supply port portion 20 is a member for supplying water stored in the water storage tank portion 10. Specifically, the water supply port 20 includes an operation lever. The operation lever is, for example, a push-down, pull-up or pivot lever. When the operation lever is operated, the water supply port unit 20 supplies the stored water to the water storage tank unit 10 or stops the water supply.

The water supply port 20 is attached to, for example, a side surface near the bottom of the water storage tank 10. Specifically, the water supply port 20 is connected to the hole 15 of the water storage tank 10. The water supply port 20 is formed of, for example, a resin material such as polypropylene (PP).

The position where the water supply port 20 is provided is not limited to the vicinity of the bottom of the water storage tank 10. For example, the water supply port 20 may be provided on the top of the water storage tank 10, such as a hot water supply pot.

[Cover (Cover)]
FIG. 5 is a schematic perspective view of the lid 30 according to the present embodiment. 6A to 6C are respectively a front view, a top view and a right side view of the lid 30 according to the present embodiment.

The lid 30 is a removable lid for closing the water injection port 14. In the present embodiment, as shown in FIGS. 5 and 6A to 6C, the ultraviolet light source unit 40 is attached to the back surface of the lid 30.

As shown in FIGS. 5 and 6A to 6C, the lid 30 includes a front surface 30a and a back surface 30b.

The surface portion 30a is a portion on the front surface side of the lid 30, and as shown in FIG. 3, when the lid 30 is closed, it covers the water injection port 14. The surface portion 30a is, for example, a disk-shaped housing. The back surface (lower surface) side of the front surface portion 30a is open, and the back surface portion 30b is connected. A gripping portion 31 is provided on the surface (upper surface) side of the surface portion 30a. The surface portion 30a is formed of, for example, a resin material such as polypropylene.

The back surface portion 30b is a portion on the back surface side of the lid portion 30, and as shown in FIG. 3, when the lid portion 30 is closed, the water storage tank portion 10 (specifically, via the water injection port portion 14) , Inner container 12). The back surface portion 30 b is, for example, a disk-shaped housing. The surface (upper surface) side of the back surface portion 30b is open, and the surface portion 30a is connected. The ultraviolet light source unit 40 is provided so as to penetrate the back surface (bottom surface) of the back surface portion 30b. The back surface portion 30b is formed of, for example, a metal material such as stainless steel.

In the present embodiment, the back surface of the lid 30 is covered with metal. Specifically, the back surface portion 30b is formed of a metal material, and the back surface (lower surface) of the back surface portion 30b is covered with metal. Thereby, the ultraviolet light which the ultraviolet light source part 40 emits can be reflected.

The back surface portion 30b may be formed of a resin material. In this case, for example, by attaching a metal plate to the lower surface of the back surface portion 30b, the back surface of the lid portion 30 can have reflectivity.

Further, as shown in FIG. 3, a drive circuit unit 60, an indicator 70 and a speaker 80 are disposed inside the lid 30. Further, as shown in FIG. 5, the open / close sensor unit 50 (lid side sensor 51) is disposed inside the lid portion 30.

In the present embodiment, the lid 30 is a screw-type lid. That is, by rotating the lid 30 with respect to the water storage tank 10, the lid 30 can close the water injection port 14.

The lid portion 30 seals the inside of the water storage tank portion 10 (a space in which water is stored) by closing the water injection port portion 14. In the present embodiment, the closure of the water injection port 14 by the lid 30 may be described as closing the lid 30.

Specifically, "closing the lid 30" means that light does not directly leak from the inside of the water storage tank unit 10. That is, in the state where the lid 30 is closed, no gap is formed between the lid 30 and the water storage tank 10, and light does not leak from the inside of the water storage tank 10 to the outside. In addition, as described later, the lid 30 includes the window 34, and a part of light is emitted to the outside of the water storage tank 10 through the window 34. Moreover, it is preferable that the water stored in the inside of the water storage tank part 10 does not leak outside through the water injection port part 14 in the state by which the cover part 30 was closed.

The “opened state” of the lid 30 is a state in which the lid 30 is not closed. For example, when the lid 30 is opened, light leaks out from the inside of the water storage tank portion 10, that is, the inside of the water storage tank portion 10 can be visually recognized from the outside.

FIG. 7 is a top view showing how the lid 30 according to the present embodiment is closed. Specifically, (a) in FIG. 7 shows a state in which the lid 30 is opened, and (b) shows a state in which the lid 30 is closed.

As shown in FIG. 7, the lid 30 is opened and closed by pivoting with the axis P passing through the center in plan view as the rotation axis. In the present embodiment, the lid 30 has a convex grip 31 that is gripped to open and close the lid 30. The user can open and close the lid 30 by gripping the grip 31 and rotating the lid 30. In addition, the screw thread screwed together is formed in each of the cover part 30 and the water storage tank part 10. As shown in FIG.

The gripping portion 31 is a portion gripped by a person who is going to open and close the lid 30 (for example, a user of the water supply device 1). The shape of the grip portion 31 is an elongated shape in plan view with respect to the lid portion 30. Specifically, the convex gripping portion 31 is formed by providing a recess around the gripping portion 31. The upper surface of the grip portion 31 and the surface (i.e., the upper surface) of the lid 30 are flush with each other. The upper surface of the gripping portion 31 is included in a second flat portion 33 described later.

When the lid 30 is rotated to a predetermined orientation (or predetermined position) with respect to the water storage tank 10, the lid 30 is in a closed state. In the present embodiment, as shown in (b) of FIG. 7, when the longitudinal direction Q of the grip portion 31 coincides with the longitudinal direction R of the water supply device 1 (that is, the Y-axis direction) It will be closed.

The lid 30 is a disk-like lid, and has a first flat portion 32 on the side surface. Specifically, as shown in FIG. 6B, the top view shape of the lid 30 is substantially circular, and a part of the circumference is missing. The missing portion is the first flat portion 32. That is, the first flat portion 32 has a flat surface provided on the side surface of the lid 30. As shown in FIGS. 6B and 6C, when the lid 30 is viewed from the top and the side, the first flat portions 32 are each shown by a substantially straight line. That is, the first flat portion 32 has a substantially rectangular flat surface.

FIG. 8 is a side view showing the lid 30 according to the present embodiment placed on the horizontal surface 95 with the first flat portion 32 facing downward.

As shown in FIG. 8, since the lid 30 has the first flat portion 32, the first flat portion 32 and the horizontal surface 95 are in contact with each other at a line (or surface). Therefore, in FIG. 8, the rotation in the left and right direction can be suppressed. As a result, the rotation of the lid 30 is suppressed, so that it is possible to suppress breakage of the lid 30 or the ultraviolet light source 40 due to, for example, collision with a peripheral object or falling.

The lid 30 has a second flat portion 33 on the surface opposite to the back surface. Specifically, as shown in FIGS. 6A to 6C, the second flat portion 33 has a substantially circular flat surface.

FIG. 9 is a side view showing the lid 30 according to the present embodiment placed on a horizontal surface 95 with the second flat portion 33 facing downward.

As shown in FIG. 9, the lid 30 is self-supporting when placed on the horizontal surface 95 with the second flat portion 33 facing vertically downward. That is, the lid 30 does not fall when placed so that the second flat portion 33 and the horizontal surface 95 are in contact with each other.

The second flat portion 33 is, for example, a plane orthogonal to the axial direction (Z-axis direction) of the ultraviolet light source unit 40. Thus, when the second flat portion 33 is directed vertically downward, the axis of the ultraviolet light source unit 40 is in the vertical direction, so that the lid 30 can be prevented from being inclined by the weight of the ultraviolet light source unit 40.

Further, the ultraviolet light source unit 40 is attached at a position facing the substantially center (center of gravity) of the second flat portion 33. Thereby, the stability in the case where the lid 30 is placed on the horizontal surface 95 with the second flat portion 33 facing vertically downward can be improved.

As described above, since the falling of the lid 30 is suppressed, it is possible to suppress breakage of the lid 30 or the ultraviolet light source unit 40 due to, for example, collision with a peripheral object or falling.

The lid 30 includes a window 34.

The window portion 34 is a portion for visually recognizing the inside of the water storage tank portion 10. In the present embodiment, as shown in FIG. 3, the window portion 34 has a through hole 34a, a diffusion member 34b, a reflection member 34c, and a translucent member 34d.

The through hole 34 a penetrates the lid 30 in the direction from the front surface to the back surface (Z-axis direction). The through holes 34a may be filled with a translucent resin material or glass material.

The diffusion member 34 b diffuses the blue and white light emitted from the ultraviolet light source unit 40 and emits the light to the outside. That is, the diffusion member 34 b emits blue and white light while the ultraviolet light source unit 40 is on. The diffusion member 34 b is provided on the surface of the lid 30 so as to cover the through hole 34 a. In the present embodiment, the diffusion member 34 b is provided on part of the surface and part of the side surface of the lid 30. As a result, as shown in FIGS. 6A to 6C, when the water supply device 1 is viewed from above or to the side of the water supply device 1, the diffusion member 34b can be visually recognized. Therefore, by visually recognizing the diffusion member 34b, it can be determined whether the ultraviolet light source unit 40 is lit.

The diffusion member 34 b is formed of, for example, a resin material. For example, the diffusion member 34 b is formed by embossing the surface of the resin material. The diffusion member 34 b may be formed of a resin material including a light diffusion material such as silica.

The reflecting member 34 c reflects blue and white light emitted from the ultraviolet light source unit 40. It is provided along the side of the through hole 34a. Therefore, the reflection member 34 c can suppress blue and white light passing through the through holes 34 a from being absorbed by the lid 30. The reflecting member 34c is, for example, a metal film such as aluminum.

The translucent member 34 d transmits blue and white light emitted from the ultraviolet light source unit 40. The translucent member 34 d is provided on the back surface of the lid 30 so as to cover the through hole 34 a. The translucent member 34d is formed of, for example, a glass material. The translucent member 34 d suppresses the infiltration of the water stored in the water storage tank unit 10 into the through hole 34 a. In addition, the translucent member 34 d absorbs the ultraviolet light emitted from the ultraviolet light source unit 40, and suppresses the radiation to the outside through the window 34.

[UV light source unit]
The ultraviolet light source unit 40 is disposed inside the water storage tank unit 10 and irradiates the water stored in the water storage tank unit 10 with ultraviolet light to sterilize the water. The ultraviolet light to be irradiated is, for example, ultraviolet light having a peak wavelength in the range of 200 nm to 400 nm. In the present embodiment, the ultraviolet light source unit 40 irradiates ultraviolet light having a peak wavelength of 253.7 nm as an example.

The ultraviolet light source unit 40 is attached to the back surface of the lid 30. Specifically, the ultraviolet light source unit 40 is provided so as to penetrate the back surface of the lid 30 (back surface 30b).

The ultraviolet light source unit 40 includes a lamp 41 and a cover 42 as shown in FIG.

The lamp 41 receives power from the outside and emits ultraviolet light. The lamp 41 is, for example, a mercury lamp that emits ultraviolet light. For example, as the lamp 41, a low pressure mercury vapor discharge lamp having a glass tube in which mercury vapor or the like is sealed can be used. Note that, instead of the lamp 41, an LED (Light Emitting Diode) that emits ultraviolet light may be used. As shown in FIG. 3, the feeding portion of the lamp 41 is provided in the back surface portion 30 b and connected to the connector 62. The lamp 41 can sterilize about 8 liters of water, for example, by irradiating for 3 minutes with 6 W of power consumption. For example, by irradiating ultraviolet light for 3 minutes with a power consumption of 6 W, it was possible to kill 99.9% of the micrococcal bacteria contained in 8 liters of water.

As shown in FIG. 3 and FIG. 5, the shape of the lamp 41 is a straight pipe. The lamp 41 is provided, for example, such that the major axis direction of the lamp 41 is orthogonal to the back surface of the lid 30. Specifically, the lamp 41 is provided so as to stand in the vicinity of the center of the rear surface of the lid 30 in plan view. The tip (lower end) of the ramp 41 is located near the bottom of the water storage tank portion 10. For example, as shown in FIG. 3, the tip of the lamp 41 and the water supply port 20 (hole 15) are positioned at substantially the same height. Thereby, the ultraviolet rays can be irradiated to the water stored in the water storage tank portion 10 directly and substantially uniformly.

The lamp 41 emits not only ultraviolet light but also blue and white light. The blue and white light is emitted to the outside through the window portion 34. Thereby, the user of the water supply device 1 can judge whether ultraviolet rays are irradiated by looking at the window part 34. In addition, the light from the LED that emits ultraviolet light also looks bluish.

The cover 42 is a cover for preventing the lamp 41 from being damaged. For example, when the cover 30 is placed on a desk or a floor, the cover 42 prevents the lamp 41 from coming into direct contact with the desk or the floor.

The cover 42 is provided to surround the lamp 41. Specifically, the cover 42 has a three-dimensional grid shape, and the lamps 41 are disposed inside the three-dimensional grid. The cover 42 is formed of, for example, a metal material such as stainless steel.

The lamp 41 and the cover 42 are immersed in the stored water when the water is stored in the water storage tank unit 10. For example, when a prescribed amount of water (for example, 8 liters) of water is stored, at least half or more of the lamp 41 is flooded. For this reason, the lamp 41 and the cover 42 are preferably waterproof.

In addition, when the ultraviolet-ray light source part 40 irradiates an ultraviolet-ray, the water supply device 1 is normally installed and fixed on the desk or a floor etc. Therefore, the water stored in the water storage tank unit 10 is not dynamic water (running water) but static water. The ultraviolet light source unit 40 irradiates ultraviolet light to static water, so that it can be sufficiently sterilized in a short period of time.

[Open / close sensor unit]
The open / close sensor unit 50 detects whether the water injection port 14 is closed by the lid 30. That is, the open / close sensor unit 50 detects whether the lid unit 30 is closed or opened.

The open / close sensor unit 50 includes a lid side sensor 51 and a tank side sensor 52 as shown in FIGS. 4 and 5. The lid side sensor 51 is, for example, built in the lid 30. The tank sensor 52 is, for example, built in the water storage tank unit 10.

In the present embodiment, the lid side sensor 51 and the tank side sensor 52 are provided in proximity to each other when the lid portion 30 is closed. For example, the lid sensor 51 and the tank sensor 52 overlap in top view when the lid 30 is closed.

The open / close sensor unit 50 is, for example, a magnetic sensor. The lid-side sensor 51 has, for example, a reed switch, and is electrically connected to the drive circuit unit 60. The tank sensor 52 is, for example, a magnet such as a permanent magnet. When the lid 30 is closed, the reed switch of the lid sensor 51 conducts and current flows. The lid-side sensor 51 outputs the current as a detection signal to the drive circuit unit 60.

The configuration of the open / close sensor unit 50 is an example and is not limited thereto. For example, the lid-side sensor 51 may have a coil, and may output a current flowing when it approaches the tank-side sensor 52 to the drive circuit unit 60 as a detection signal.

[Drive circuit section]
The drive circuit unit 60 controls lighting and extinguishing of the ultraviolet light source unit 40. Specifically, the drive circuit unit 60 controls the timing at which the ultraviolet light source unit 40 is turned on and the timing at which it is turned off. The drive circuit unit 60 may perform control to change the intensity of the ultraviolet light emitted by the ultraviolet light source unit 40 or the period of irradiation of the ultraviolet light.

In the present embodiment, the drive circuit unit 60 executes a lighting enable mode in which the ultraviolet light source unit 40 can be lit, and a lighting prohibition mode in which the lighting of the ultraviolet light source unit 40 is prohibited. In the lighting enable mode, when the power switch 63 is pressed, the drive circuit unit 60 lights the ultraviolet light source unit 40. In the lighting prohibition mode, even if the power switch 63 is pressed, the drive circuit unit 60 does not light the ultraviolet light source unit 40. The drive circuit unit 60 switches between the lighting enable mode and the lighting prohibition mode based on the detection result by the open / close sensor unit 50.

Specifically, when the open / close sensor unit 50 does not detect that the water injection port 14 is closed, the drive circuit unit 60 prohibits the lighting of the ultraviolet light source unit 40. That is, the drive circuit unit 60 executes the lighting prohibition mode when the cover 30 is opened. Specifically, the supply of power to the ultraviolet light source unit 40 is prohibited. Further, the drive circuit unit 60 executes the lighting enable mode only when the lid 30 is closed. Specifically, the drive circuit unit 60 can supply power to the ultraviolet light source unit 40. When the lid 30 is opened while the ultraviolet light source unit 40 is lit, the drive circuit unit 60 turns off the ultraviolet light source unit 40 and shifts to the lighting prohibition mode.

As shown in FIG. 3, the drive circuit unit 60 includes an inverter 61, a connector 62, a power switch 63, a main circuit board 64, and a timer unit 65. Although not shown, the inverter 61, the connector 62, the power switch 63, the main circuit board 64, and the timer unit 65 are electrically connected by a cable or a wiring such as a metal pattern provided on the substrate. There is.

The inverter 61 generates AC power to be supplied to the lamp 41. Specifically, the inverter 61 converts the power (for example, system power) supplied from the external power supply into a desired frequency, and supplies the converted AC power to the lamp 41 through the connector 62.

The connector 62 is an example of a connection unit for supplying power to the lamp 41. The connector 62 is electrically connected to the inverter 61.

The power switch 63 is a switch for starting lighting of the ultraviolet light source unit 40. When the power switch 63 is pressed, the main circuit board 64 and the inverter 61 supply power to the lamp 41. When the power switch 63 is pressed while the ultraviolet light source unit 40 is on, the ultraviolet light source unit 40 may be turned off.

The main circuit board 64 is a circuit board for controlling start and stop of the supply of power to the lamp 41. Specifically, the main circuit board 64 detects that the power switch 63 has been pressed, and starts supplying power to the lamp 41.

In the present embodiment, the main circuit board 64 acquires the detection signal output from the open / close sensor unit 50. The main circuit board 64 executes the lighting enable mode only when it is confirmed by the detection signal that the lid 30 is closed.

The timer unit 65 counts the lighting time of the ultraviolet light source unit 40. The timer unit 65 is provided, for example, on the main circuit board 64. The timer unit 65 starts counting from the timing when the irradiation of the ultraviolet light by the ultraviolet light source unit 40 is started. The timer unit 65 outputs a turn-off timing signal to the main circuit board 64 at a timing when a preset period (hereinafter referred to as “set time”) has elapsed from the start of counting. When receiving the turn-off timing signal, the main circuit board 64 stops the supply of the power to the lamp 41 and stops the irradiation of the ultraviolet light by the ultraviolet light source unit 40.

The setting time is, for example, 3 minutes. Note that a plurality of set times may be set. In this case, the user can select one set time from a plurality of set times. The longer the setting time, the higher the bactericidal effect of non-sterile water can be.

In the present embodiment, the timer unit 65 outputs a count signal corresponding to the count to the indicator 70. For example, the timer unit 65 outputs a count signal indicating a count value or a remaining time. In addition, the timer unit 65 may output a count signal or a turn-off timing signal to the speaker 80.

A microcomputer (micro controller) is mounted on the main circuit board 64, for example. The microcomputer performs lighting control of the ultraviolet light source unit 40, display control of the indicator 70, and sound output control of the speaker 80. Further, the microcomputer may have the function of the timer unit 65.

[Display section]
The indicator 70 is an example of a display unit that performs display according to the count by the timer unit 65. The indicator 70 performs different display according to the count by the timer unit 65, for example.

As shown in FIG. 3, the indicator 70 includes an LED substrate 71 and a translucent cover 72.

The LED substrate 71 has a plurality of LED elements mounted thereon. The plurality of LED elements sequentially emit light according to the count by the timer unit 65. The plurality of LED elements emit visible light such as, for example, red or blue.

The translucent cover 72 is a cover that transmits light emitted from the LED substrate 71. The translucent cover 72 suppresses the entry of foreign matter such as dust or moisture into the inside of the lid 30.

FIG. 10 is a top view showing the appearance of the indicator 70 in use of the water dispenser 1 according to the present embodiment. Specifically, (a) of FIG. 10 shows a point in time when the irradiation of the ultraviolet light by the ultraviolet light source unit 40 is started. (B) of FIG. 10 shows the point in time after which setting time (for example, 3 minutes) has not passed after irradiation of an ultraviolet-ray is started. (C) of FIG. 10 shows the time when the set time has elapsed after the start of the irradiation of the ultraviolet light.

In addition, in FIG. 10, the shaded area of the diagonal line indicates that the LED element emits light. Further, the hatching of the dots attached to the window portion 34 indicates that the ultraviolet light source unit 40 irradiates the ultraviolet light, and the blue light is visible from the outside.

As shown in (a) of FIG. 10, for example, at the time when the irradiation of ultraviolet light is started, the indicator 70 is emitting light by only one LED element. As shown in (b) of FIG. 10, the number of LED elements emitting light sequentially increases with the passage of time. As shown in (c) of FIG. 10, after all the LED elements emit light, the irradiation of the ultraviolet light ends.

The display method of the count by the indicator 70 is not limited to this. The indicator 70 is, for example, a segment display, and may display the count value (or the remaining time) as a digital number. Alternatively, the indicator 70 may blink the LED element and change the frequency of the blinking according to the count. Further, the indicator 70 may change the emission color of the LED element according to the count.

[Sound output part]
The speaker 80 is an example of a sound output unit that emits a sound according to the open / close state of the lid 30 detected by the open / close sensor unit 50. The speaker 80 is provided, for example, on the main circuit board 64.

In the present embodiment, the speaker 80 emits a sound effect (first sound effect) when the open / close sensor unit 50 detects that the lid 30 is closed. The speaker 80 emits a warning sound when the open / close sensor unit 50 detects that the lid unit 30 is opened.

Further, in the present embodiment, the speaker 80 emits a sound in accordance with the lighting state of the ultraviolet light source unit 40. Specifically, the speaker 80 emits a second sound effect when the ultraviolet light source unit 40 starts lighting. The speaker 80 emits a third sound effect when the ultraviolet light source unit 40 is turned off after the set time has elapsed.

The first sound effect, the second sound effect, the third sound effect, and the warning sound are, for example, mutually different sounds. Specifically, the pitch of the sound, the magnitude of the sound, or the number or timing of emitting the sound are different.

The speaker 80 may output voice or music instead of sound effects or warning sounds.

[Toride department]
The handle portion 90 is a portion gripped by the user when carrying the water supply device 1. The handle portion 90 is attached to the water storage tank portion 10. The handle portion 90 is formed of, for example, a resin material such as polypropylene.

[Function configuration]
Subsequently, the functional configuration of the water dispenser 1 according to the present embodiment will be described with reference to FIG. FIG. 11 is a functional block diagram showing the configuration of the water supply device 1 according to the present embodiment.

As shown in FIG. 11, the water dispenser 1 includes a receiving unit 110, a detection unit 120, a light source unit 130, a control unit 140, a timer unit 150, a sound output unit 160, and a display unit 170.

The receiving unit 110 receives the start of the irradiation of ultraviolet light by the light source unit 130 (that is, the lighting instruction). The receiving unit 110 corresponds to the power switch 63. The receiving unit 110 may receive the stop of the irradiation of the ultraviolet light (that is, the turn-off instruction). The receiving unit 110 may receive the setting of the lighting period, the setting of the irradiation intensity, and the like.

The detection unit 120 detects whether the lid 30 is closed. The detection unit 120 corresponds to the open / close sensor unit 50. The detection unit 120 detects whether the lid 30 is closed and outputs the detection result to the control unit 140.

The light source unit 130 irradiates the water stored in the water storage tank unit 10 with ultraviolet light. The light source unit 130 corresponds to the ultraviolet light source unit 40. The light source unit 130 turns on and off ultraviolet light based on the control of turning on or off by the control unit 140.

The control unit 140 controls the operations of the light source unit 130, the sound output unit 160, and the display unit 170. The control unit 140 corresponds to the drive circuit unit 60. Specifically, the control unit 140 corresponds to a microcomputer mounted on the main circuit board 64.

In the present embodiment, control unit 140 controls the operation mode of water dispenser 1.

Specifically, when the detection unit 120 detects that the lid 30 is closed, the control unit 140 shifts to the lighting enable mode. At this time, the control unit 140 causes the sound output unit 160 to output an effect sound (first sound effect).

For example, in the lighting enable mode, the control unit 140 causes the light source unit 130 to emit ultraviolet light when the receiving unit 110 receives a lighting instruction. At this time, the control unit 140 causes the sound output unit 160 to output a sound effect (second sound effect).

Also, when notified by the timer unit 150 that the set time has elapsed, the control unit 140 causes the light source unit 130 to stop the irradiation of the ultraviolet light. At this time, the control unit 140 causes the sound output unit 160 to output a sound effect (third sound effect).

The control unit 140 causes the light source unit 130 to stop the irradiation of the ultraviolet light when the detection unit 120 detects that the lid 30 is opened while the light source unit 130 is irradiating the ultraviolet light. Further, at this time, the control unit 140 shifts from the lighting enable mode to the lighting prohibition mode.

In the lighting prohibition mode, the control unit 140 does not cause the light source unit 130 to emit the ultraviolet light even if the receiving unit 110 receives the lighting instruction. For example, instead of causing the light source unit 130 to emit ultraviolet light, the control unit 140 causes the sound output unit 160 to output a warning sound.

The timer unit 150 counts the lighting time of the light source unit 130. The timer unit 150 corresponds to the timer unit 65. The timer unit 150 notifies the control unit 140 when the lighting time of the light source unit 130 reaches the set time.

The sound output unit 160 emits a sound according to the open / close state of the lid 30 detected by the detection unit 120. The sound output unit 160 corresponds to the speaker 80. Further, the sound output unit 160 emits a sound according to the lighting state of the light source unit 130. Specifically, the sound output unit 160 emits a sound effect or a warning sound based on the control by the control unit 140.

The display unit 170 performs display according to the count by the timer unit 150. The display unit 170 corresponds to the indicator 70. The display unit 170 performs different display according to the lighting time of the light source unit 130 based on the control of the control unit 140.

[Operation]
Then, operation | movement of the water dispenser 1 which concerns on this Embodiment is demonstrated using FIG.12 and FIG.13.

FIG. 12 is a flowchart showing the operation of the water dispenser 1 according to the present embodiment. FIG. 13: is a figure which shows typically operation | movement of the water dispenser 1 which concerns on this Embodiment.

First, as shown in (a) of FIG. 13, the user removes the lid portion 30 of the water supply device 1 and pours water into the water storage tank portion 10 via the water injection port portion 14. Specifically, the water is non-sterile water, for example, tap water supplied from the faucet 200.

Next, as shown in (b) of FIG. 13, the user attaches the lid 30 to the water storage tank 10. Specifically, the user holds the grip 31 with the hand 210 and rotates the lid 30 to close the lid 30. At this time, when the lid 30 is properly closed, the speaker 80 emits a first sound effect (for example, "beep").

As described above, after the water is stored in the water storage tank unit 10 by the user, the water dispenser 1 can perform sterilization of the stored water. That is, the drive circuit unit 60 shifts to the light enable mode.

Specifically, first, as shown in FIG. 12, the water supply device 1 stands by to receive a lighting instruction from the user (No in step S10). Specifically, as shown in (c) of FIG. 13, for example, the user's hand 210 waits for the power switch 63 to be pressed.

When the lighting instruction is received (Yes in step S10), the drive circuit unit 60 confirms that the lid 30 is closed by the open / close sensor unit 50 (step S12). When the lid 30 is not closed (No in step S12), the speaker 80 emits a warning sound (step S14). At this time, the speaker 80 may continue to emit a warning sound periodically until the lid 30 is closed.

When the lid 30 is closed (Yes in step S12), the ultraviolet light source unit 40 starts irradiation of the water stored in the water storage tank unit 10 with ultraviolet light (step S16). At this time, as shown in (c) of FIG. 13, the speaker 80 may emit a second sound effect (for example, “pipi”).

The timer unit 65 starts counting and stands by until the set time passes (No in step S18). Specifically, as shown in (d) of FIG. 13, the ultraviolet light source unit 40 continues to irradiate ultraviolet light. Further, the indicator 70 performs display according to the count. At this time, the window 34 looks pale blue.

When the set time has elapsed (Yes in step S18), the ultraviolet light source unit 40 stops the irradiation of the ultraviolet light. Further, as shown in (e) of FIG. 13, the speaker 80 emits a third sound effect (for example, "peep") as an end sound (step S20). Thus, the ultraviolet light is directly irradiated to the non-sterile water stored in the water storage tank 10 during the set time, so that the sterilization can be sufficiently performed.

At this time, the indicator 70 ends the display. That is, the LED substrate 71 ends the light emission. In addition, since the bluish light is not emitted from the ultraviolet light source unit 40, the window 34 emits bluish light and can not be seen.

Finally, the user can pour the water (sterilized water) stored in the water storage tank unit 10 into the cup 220 by operating the water supply port 20 as necessary. Thereby, sterilizing water can be utilized as drinking water etc.

[Effect, etc.]
Below, the effect by the water dispenser 1 which concerns on this Embodiment, etc. are demonstrated.

In the conventional water flow type water sterilizer, as described above, there is a problem that a large amount of water can not be sufficiently sterilized in a short period of time.

On the other hand, in the water dispenser 1 according to the present embodiment, the water storage tank unit 10 having the water injection port unit 14 for injecting water to the inside, and the water supply port for supplying water stored in the water storage tank unit 10 The unit 20 includes an ultraviolet light source unit 40 disposed inside the water storage tank unit 10 and irradiating the water stored in the water storage tank unit 10 with ultraviolet light to sterilize the water.

Thus, the ultraviolet light source unit 40 irradiates the water stored in the water storage tank unit 10 with the ultraviolet light, so that the stored water can be collectively sterilized. In addition, since the ultraviolet light source unit 40 is disposed inside the water storage tank unit 10, it is possible to irradiate ultraviolet light so as to reach the whole of the water stored in the water storage tank unit 10, so it has an excellent sterilizing effect. . Therefore, according to the water dispenser 1 according to the present embodiment, a large amount of water can be sufficiently sterilized in a short period of time.

Moreover, the conventional water sterilizer also has the problem that the sterilizing water once stored in the tank can not be disinfected again. Therefore, if a predetermined period of time has elapsed after sterilization, there is a risk that bacteria may be propagated. For this reason, it is necessary to discard all the sterilizing water stored in the tank. Alternatively, there is a risk that the water in which the bacteria has propagated may be used as drinking water as it is.

On the other hand, according to the water dispenser 1 which concerns on this Embodiment, sterilization is performed by irradiating an ultraviolet-ray inside the water storage tank part 10. As shown in FIG. That is, in the water dispenser 1, the internal space of the water storage tank part 10 is utilized as space for both sterilization and water storage. For this reason, since it is possible to sterilize the sterilized water once sterilized, it is possible to always provide highly safe water as potable water and the like.

Moreover, since the ultraviolet rays are also irradiated to the inner surface of the water storage tank portion 10, the water storage tank portion 10 itself can be sterilized. Therefore, more safe water can be provided.

Moreover, the conventional water sterilizer is directly connected to a water supply and used. That is, specialized work such as connection work to a water pipe is required, and there is also a problem that installing the water sterilizer is complicated. Furthermore, there is also a problem that the installation location of the water sterilizer is limited in order to connect to the water pipe.

On the other hand, according to the water dispenser 1 which concerns on this Embodiment, since the water storage tank part 10 has the water injection port part 14, water can be poured into the water storage tank part 10 from the faucet etc. of a water supply. That is, it is not necessary to connect the ultraviolet light source unit 40 to a water pipe or the like. Therefore, the water dispenser 1 is portable.

Furthermore, according to the water supply device 1, since the ultraviolet light source unit 40 is disposed inside the water storage tank unit 10, the tank unit and the drainage pipe for sterilization treatment are compared with the conventional water flow type water sterilization apparatus. There is no need to provide it, and the structure can be simplified. By simplifying the structure, cost reduction can be realized, and the miniaturization and weight reduction of the water dispenser 1 can be realized. Therefore, the water dispenser 1 can be carried more easily.

Further, for example, the water dispenser 1 further includes a removable lid 30 for closing the water injection port 14.

Thereby, since the cover part 30 can block the water injection port part 14, it can suppress that the ultraviolet-ray which the ultraviolet-ray light source part 40 irradiates leaks out of the water dispenser 1. As shown in FIG. Moreover, since it can suppress that an ultraviolet ray leaks out by the cover part 30, the water injection port part 14 can be enlarged. Therefore, the time required to fill the water storage tank 10 can be shortened. Moreover, it can suppress that the water stored by the water storage tank part 10 overflows.

Further, for example, the ultraviolet light source unit 40 is attached to the back surface of the lid 30.

As a result, since the ultraviolet light source unit 40 is disposed inside the water storage tank unit 10 when the water dispenser 1 is in use, that is, when the lid 30 is closed, the water stored in the water storage tank unit 10 Can be sterilized. Further, the ultraviolet light source unit 40 can be easily taken out from the water storage tank 10 by removing the lid 30 from the water storage tank 10. Therefore, for example, the inside of the water storage tank portion 10 can be easily cleaned, the cleanliness of the water supply device 1 can be easily maintained, and the reproduction of the sterilization can be suppressed to the stored sterilizing water.

Further, for example, the water dispenser 1 further includes an open / close sensor unit 50 that detects whether the water injection port 14 is closed by the lid 30, and a drive circuit unit that controls lighting and extinguishing of the ultraviolet light source unit 40. The driving circuit unit 60 prohibits the lighting of the ultraviolet light source unit 40 when the open / close sensor unit 50 does not detect that the water injection port 14 is closed.

Thus, when the lid 30 is not closed, no ultraviolet light is emitted. Therefore, it can suppress that an ultraviolet-ray leaks out of the water dispenser 1 accidentally, and can suppress the bad influence to a user's human body, or the damage to goods.

Also, for example, the water dispenser 1 further includes a sound output unit 160 (speaker 80) that emits a sound according to the open / close state of the lid 30 detected by the open / close sensor unit 50.

As a result, since a sound is emitted according to the open / close state of the lid 30, it is possible to inform the user, for example, whether the lid 30 is properly closed. Therefore, according to the water dispenser 1 which concerns on this Embodiment, user convenience can be improved.

Also, for example, the lid 30 includes a window 34 for visualizing the inside of the water storage tank 10.

Thereby, during sterilization processing (that is, during irradiation of ultraviolet light), the user can visually confirm whether or not the ultraviolet light is irradiated through the window portion 34. That is, the user can visually check the operation state of the ultraviolet light source unit 40. Therefore, for example, it is possible to easily know the replacement time and the like based on the life of the lamp 41.

Also, for example, the lid 30 is a disk-like lid, and has a first flat portion 32 on the side surface.

Thus, when the lid 30 is placed on a desk or a floor, the sideward rotation of the lid 30 can be suppressed by the first flat portion 32 contacting the desk or the floor. For example, when the water storage tank unit 10 is to be filled with water, it is conceivable that the lid unit 30 be removed and placed on a desk or a floor in order to perform the water filling process smoothly. In this case, when the first flat portion 32 contacts the desk or the floor, it is possible to suppress the lid 30 from rolling.

Therefore, for example, it is possible to suppress that the lid 30 falls and falls from the desk or collides with a peripheral object to damage the lid 30 itself or the ultraviolet light source 40. In particular, when the glass member is used for a part of the ultraviolet light source unit 40, breakage of the glass member can be suppressed. In addition, even when the drive circuit unit 60 is housed inside the lid 30, the failure of the drive circuit unit 60 can be suppressed.

Also, for example, the lid 30 has the second flat portion 33 on the surface opposite to the back surface, and stands independently when the second flat portion 33 is placed vertically on the horizontal surface 95.

Thereby, when the lid 30 is placed on a desk or a floor with the second flat portion 33 facing downward, the lid 30 becomes self-supporting. For example, when the water storage tank unit 10 is to be filled with water, it is conceivable that the lid unit 30 be removed and placed on a desk or a floor in order to perform the water filling process smoothly. In this case, the lid 30 can stand alone, thereby suppressing the lid 30 from falling.

Therefore, for example, it is possible to suppress that the lid 30 falls down and falls from the desk or collides with a peripheral object to damage the lid 30 itself or the ultraviolet light source 40. In particular, when the glass member is used for a part of the ultraviolet light source unit 40, breakage of the glass member can be suppressed. In addition, even when the drive circuit unit 60 is housed inside the lid 30, the failure of the drive circuit unit 60 can be suppressed.

Also, for example, the lid 30 has a convex grip 31 that is gripped to open and close the lid 30, and the shape of the grip 31 is an elongated shape in plan view with respect to the lid 30.

Accordingly, the user can easily close the lid 30 by gripping the grip 31. In addition, since the grip portion 31 is elongated in plan view, the user can determine whether the lid 30 is properly closed by confirming the longitudinal direction of the grip portion 31. For example, when viewed from the front of the water dispenser 1, the user can easily close the lid 30 by closing the holding portion 31 so that the longitudinal direction is straight (overlaps in the Y-axis direction).

In addition, for example, the water dispenser 1 further includes a timer unit 65 that counts the lighting time of the ultraviolet light source unit 40, and a display unit 170 (indicator 70) that performs display according to the count by the timer unit 65.

This makes it possible to easily inform the user of the time or timing until the end of the sterilization process. Therefore, user convenience can be enhanced.

Further, for example, the inner surface of the water storage tank portion 10 and the back surface of the lid portion 30 are covered with metal.

Thereby, since metal reflects an ultraviolet-ray, deterioration by the ultraviolet-ray of resin which comprises the water storage tank part 10 and the cover part 30 can be suppressed. In addition, since the ultraviolet light not absorbed by the inner surface of the water storage tank unit 10 or the lid unit 30 returns to the water stored inside the water dispenser 1, the water can be efficiently disinfected in a short time. .

Also, for example, the water supply device 1 further includes a sound output unit 160 (speaker 80) that emits a sound according to the lighting state of the ultraviolet light source unit 40.

Thus, since the sound is emitted according to the lighting state of the ultraviolet light source unit 40, for example, the user can be notified of the start and end of the irradiation of the ultraviolet light. Therefore, user convenience can be enhanced.

Moreover, the lid (lid 30) according to the present embodiment is, for example, a lid that can be attached to and detached from the water supply device 1, and the ultraviolet light source unit 40 is attached to the back surface of the lid. When the lid is attached to the water supply device 40, the water stored in the water supply device 1 is irradiated with ultraviolet light to sterilize the water.

Thereby, by using the lid 30, as in the case of the water dispenser 1 described above, a large amount of water can be sufficiently disinfected in a short period of time.

(Others)
As mentioned above, although the water dispenser which concerns on this invention was demonstrated based on the said embodiment, this invention is not limited to said embodiment.

For example, although the above-mentioned embodiment showed an example in which the ultraviolet light source part 40 was attached to the back of lid 30, it does not restrict to this. The ultraviolet light source unit 40 may be attached to the inside of the water storage tank unit 10. For example, the ultraviolet light source unit 40 may be attached to the inner bottom or the inner side surface of the water storage tank unit 10.

Further, for example, in the above-described embodiment, although the water supply device 1 shows the example including the lid 30, it is not limited thereto. The water dispenser 1 may not have the lid 30. In this case, the ultraviolet light source unit 40 is attached to the inner surface of the water storage tank unit 10, for example. In addition, the water injection port 14 has a small opening and is disposed at a distance from the ultraviolet light source 40 so that the ultraviolet light emitted by the ultraviolet light source 40 does not leak to the outside. Alternatively, for example, a hose attached to a tap of a water supply may be attached to the water inlet 14.

Further, for example, in the above-described embodiment, the example in which the water injection port 14 is closed (the lid 30 is closed) by rotating the lid 30 is described, but the present invention is not limited thereto. For example, the water injection port 14 may be closed by pushing the lid 30 into the water storage tank 10.

Further, for example, in the above-described embodiment, the example in which the lid 30 is rotated by gripping the convex grip 31 is described, but the present invention is not limited thereto. For example, the grip 31 may be a recess. The user can put a hand in the recess to turn the lid 30.

Further, for example, in the above embodiment, although an example in which the convex gripping portion 31 and the surface (upper surface) of the lid 30 are flush with each other has been described, the present invention is not limited thereto. For example, the gripping portion 31 may protrude from the upper surface of the lid 30.

Further, for example, in the above-described embodiment, although the example in which the lid 30 is a disk-shaped lid is described, the present invention is not limited thereto. The lid 30 may be a rectangular lid. Similarly, although an example in which the shape of the water storage tank portion 10 is cylindrical is shown, the present invention is not limited to this. The shape of the water storage tank portion 10 may be a square tube shape.

Further, a plurality of legs may be provided at the bottom of the water storage tank 10. Thereby, when the water dispenser 1 is installed in installation surfaces, such as a desk, the height of the water supply port part 20 from an installation surface can be made high. Therefore, water supply can be facilitated.

Also, for example, the water supply device 1 may have a function of restricting the opening and closing of the lid 30. For example, while the ultraviolet light source unit 40 is irradiating the ultraviolet light, the lid 30 may be fixed so as not to be opened.

Further, for example, the water dispenser 1 may not include at least one of the open / close sensor unit 50, the drive circuit unit 60, the indicator 70, the speaker 80, and the handle unit 90. Further, the positions at which the open / close sensor unit 50, the drive circuit unit 60, the indicator 70, the speaker 80, and the handle unit 90 are provided are not limited to the examples shown in the embodiments. For example, the indicator 70 may be provided to the water storage tank unit 10 instead of the lid 30.

In addition, the present invention can be realized by arbitrarily combining components and functions in each embodiment without departing from the scope of the present invention or embodiments obtained by applying various modifications that those skilled in the art may think to each embodiment. The form is also included in the present invention.
