Description

  The present invention relates to a sterilization container having a liquid sterilization function.

  Conventionally, tap water or the like distributed in homes is sterilized with ultraviolet rays and then used as drinking water. This is because even tap water may be contaminated with bacteria such as micrococcus or E. coli. In particular, in developing countries and the like, even household tap water may not be sufficiently sterilized, or bacteria may be mixed during water distribution.

  As a water sterilizer that can be used at home, a technique is known in which raw water from a water supply is passed through a filter and then sterilized by irradiating the filtered water with ultraviolet rays, and the sterilized water is stored in a tank or the like. (For example, refer to 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 drinking water or cooking water.

(Embodiment 1)
[Overview]
First, the outline | summary of the water supply apparatus which concerns on this Embodiment is demonstrated using FIGS. 1-3.

  FIG. 1 is a schematic perspective view of a water supply 1 according to the present embodiment. FIG. 2 is a top view of the water feeder 1 according to the present embodiment. FIG. 3 is a cross-sectional view of water dispenser 1 according to the present embodiment taken along line III-III in FIG. Moreover, in each figure, let the left-right direction of the water feeder 1 be an x-axis direction, the front-back direction is a y-axis direction, and an up-down direction is a z-axis direction.

  The water supply device 1 according to the present embodiment is an example of a sterilization container that sterilizes a liquid and stores the sterilized liquid. The water dispenser 1 provides (provides) water to the user, for example, drinking water or cooking water. Specifically, the water feeder 1 is sterilized by irradiating ultraviolet light (UV light) to water such as tap water, well water, spring water, rainwater (hereinafter referred to as “unsterilized water”). The water supply 1 provides sterilized water (hereinafter referred to as “sterilized water”) as drinking water or the like.

  As shown in FIG. 1, the water supply device 1 according to the present embodiment is a small, lightweight, portable water supply device called a so-called water jug. The water feeder 1 may be installed in a home or the like, or may be used outdoors.

  As shown in FIGS. 1 to 3, the water dispenser 1 includes a container unit 10, a faucet unit 20, a lid unit 30, an ultraviolet light source unit 40, and an open / close sensor unit 50 (see FIGS. 4 and 5). A drive circuit unit 60, an indicator 70, a window unit 80, and a display panel 90.

  Below, the component with which the water feeder 1 which concerns on this Embodiment is provided is demonstrated in detail, referring FIGS. 1-3 suitably.

[Container]
FIG. 4 is a schematic perspective view showing the container unit 10 according to the present embodiment.

  As shown in FIG. 4, the container part 10 is a container part in which a liquid is stored. The container part 10 has the opening part 11 for injecting liquid inside. Specifically, the liquid is water such as tap water, but may be drinking water such as tea or juice. For example, unsterilized water is injected into the container portion 10 through the opening 11, and the injected unsterilized water is stored. The stored unsterilized water is irradiated with ultraviolet rays by the ultraviolet light source unit 40 shown in FIG. 3 and then supplied (discharged) to the outside through the water tap unit 20.

  As shown in FIG. 4, a hole 12 is provided on the side surface near the bottom of the container 10. A water faucet 20 is attached to the hole 12. When the water tap 20 is operated, the liquid stored in the container 10 is supplied to the outside through the hole 12.

  Although the capacity | capacitance of the container part 10 is 6L (liter)-10L, for example, it is not restricted to this. Although the shape of the container part 10 is a bottomed substantially cylindrical shape as shown in FIG. 4, it is not restricted to this. The shape of the container portion 10 may be a bottomed rectangular tube shape, or may be a shape in which the opening 11 is smaller than the bottom portion (so-called bottle shape).

  In this Embodiment, the container part 10 has a heat retention function. Specifically, the container part 10 has a double structure of an inner container and an outer container. The space between the inner container and the outer container is a decompressed space such as a vacuum. Thereby, heat conduction is suppressed between the inner container and the outer container, and the temperature of the liquid stored inside can be maintained.

  The inner surface of the container part 10 is covered with metal. Specifically, the inner container of the container unit 10 is formed using a metal material such as stainless steel or aluminum. Thereby, since the ultraviolet-ray which the ultraviolet light source part 40 emits can be reflected in the inner surface of the container part 10, a liquid can be sterilized efficiently. In addition, the outer container of the container part 10 is formed from resin materials, such as a polypropylene (PP), for example.

  In addition, the container part 10 does not need to have a heat retention function, and does not need to have a double structure. Moreover, the container part 10 may be formed using the resin material, and the inner surface may be covered with the metal material by the plating process.

  In the present embodiment, the opening 11 is closed by a lid 30 as shown in FIG. The plan view shape (top view shape) of the opening 11 is substantially circular. Thereby, the opening part 11 can be closed by the cover part 30 by rotating the cover part 30 and screwing. As shown in FIG. 4, a container-side sensor 52 (open / close sensor section 50) is provided in the vicinity of the opening 11 of the container section 10.

  The method for closing the opening 11 by the lid 30 is not limited to the screw type. For example, you may provide the recessed part or convex part which each engages with the opening part 11 and the cover part 30. FIG. For example, the opening 11 may be closed by the lid 30 by fitting the concave portion into the convex portion. In addition, if it is simply plugged, there is no need to provide a locking mechanism.

[Water faucet part]
The water tap part 20 is an example of a supply plug part for supplying the liquid stored in the container part 10. Specifically, the water tap part 20 includes an operation lever. The operation lever is, for example, a push-down, pull-up, or rotary lever. When the operation lever is operated, the water tap part 20 supplies water stored in the container part 10 or stops water supply.

  The faucet part 20 is attached to the side part near the bottom part of the container part 10, for example. Specifically, the water tap part 20 is connected to the hole 12 of the container part 10. The water tap part 20 is formed from resin materials, such as a polypropylene (PP), for example.

  In addition, the position where the water tap part 20 is provided is not limited to the vicinity of the bottom part of the container part 10. For example, the water tap part 20 may be provided in the upper part of the container part 10 like a hot water pot.

[Cover (Cover)]
FIG. 5 is a schematic perspective view of the lid 30 according to the present embodiment.

  The lid 30 is a detachable lid for closing the opening 11. In the present embodiment, as shown in FIG. 5, an ultraviolet light source unit 40 is attached to the back surface of the lid unit 30. Inside the lid part 30, an open / close sensor part 50 (lid side sensor 51) is arranged. As shown in FIG. 3, a drive circuit unit 60 is disposed inside the lid unit 30.

  As shown in FIGS. 3 and 5, the lid portion 30 includes a front surface portion 31, a back surface portion 32, and a metal plate 33.

  The front surface portion 31 is a portion on the front (front) surface side of the lid portion 30 and covers the opening 11 when the lid portion 30 is closed as shown in FIG. The front surface portion 31 is, for example, a flat, bottomed, substantially cylindrical housing whose back surface (lower surface) is open and whose front surface (upper surface) corresponds to the bottom. The back surface portion 32 is connected to the lower surface side of the front surface portion 31 so as to form a space for disposing the drive circuit portion 60 therein. The surface portion 31 is formed from a resin material such as polypropylene (PP), for example.

  The back surface portion 32 is a portion on the back surface side of the lid portion 30, and covers the opening 11 when the lid portion 30 is closed as shown in FIG. 3. The back surface portion 32 is, for example, a flat bottomed substantially cylindrical housing whose front surface (upper surface) side is open and whose back surface (lower surface) side corresponds to the bottom. In the present embodiment, the ultraviolet light source unit 40 is provided so as to penetrate the back surface (lower surface) of the back surface portion 32. The back surface portion 32 is made of a resin material such as polypropylene (PP), for example.

  The metal plate 33 is a metal member provided so as to cover the back surface (lower surface) of the lid portion 30. The metal plate 33 is made of a metal material such as stainless steel, for example. Thereby, the ultraviolet rays emitted from the ultraviolet light source unit 40 can be reflected toward the inside of the container unit 10.

  Instead of providing the metal plate 33 on the lower surface of the back surface portion 32, the back surface portion 32 itself may be formed of a metal material.

  In the present embodiment, lid portion 30 is a screw-type lid. That is, the lid 30 can block the opening 11 by rotating the lid 30 with respect to the container 10.

  The lid 30 seals the inside of the container 10 (the space in which water is stored) by closing the opening 11. In the present embodiment, the closing of the opening 30 by the lid 30 may be described as closing the lid 30.

  Specifically, “closing the lid portion 30” means that light does not leak directly from the inside of the container portion 10. That is, when the lid 30 is closed, no gap is formed between the lid 30 and the container 10, and light does not leak from the inside of the container 10 to the outside. In the present embodiment, the water feeder 1 includes a window portion 80, and a part of the light is emitted to the outside of the container portion 10 through the window portion 80. In addition, in a state where the lid 30 is closed, it is preferable that the water stored inside the container 10 does not leak outside through the opening 11.

  The “open state” of the lid 30 is a state where the lid 30 is not closed. For example, when the lid portion 30 is opened, light leaks from the inside of the container portion 10, that is, the inside of the container portion 10 is visible from the outside.

  Although not shown, the lid 30 is provided with a plug insertion port. When the plug is connected to the insertion port, power for operating the ultraviolet light source unit 40 and the indicator 70 is supplied to the drive circuit unit 60. The lid 30 may be provided with a battery instead of or in addition to the insertion port.

[Ultraviolet light source]
The ultraviolet light source unit 40 is disposed inside the container unit 10 and sterilizes the liquid by irradiating the liquid stored in the container unit 10 with ultraviolet rays. The ultraviolet rays to be irradiated are, for example, ultraviolet rays 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 rays 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 unit 30. Specifically, the ultraviolet light source unit 40 is provided so as to penetrate the back surface of the lid portion 30 (back surface portion 32).

  As shown in FIGS. 3 and 5, the ultraviolet light source unit 40 includes a lamp 41 and a cover 42.

  The lamp 41 emits ultraviolet rays upon receiving electric power from the outside. The lamp 41 is, for example, a mercury lamp that emits ultraviolet rays. For example, as the lamp 41, a low-pressure mercury vapor discharge lamp having a glass tube sealed with mercury vapor or the like can be used. Instead of the lamp 41, an LED (Light Emitting Diode) that emits ultraviolet light may be used. As shown in FIG. 3, the power feeding portion of the lamp 41 is provided in the back surface portion 32 and is connected to a connector (not shown) connected to the drive circuit portion 60. For example, the lamp 41 can sterilize about 8 L of water by irradiating with a power consumption of 6 W for 3 minutes. For example, 99.9% of micrococcus bacteria contained in 8 L of water could be sterilized by irradiating ultraviolet rays for 3 minutes with 6 W of power consumption.

  As shown in FIGS. 3 and 5, the shape of the lamp 41 is a straight tube. The lamp 41 is provided, for example, so that the major axis direction of the lamp 41 is orthogonal to the back surface of the lid portion 30 (that is, parallel to the z-axis direction). Specifically, the lamp 41 is provided so as to stand near the center of the back surface of the lid portion 30 in plan view. The lamp 41 is provided along the axis of rotation when the lid 30 is opened and closed. The tip (lower end) of the lamp 41 is located near the bottom of the container part 10. For example, as shown in FIG. 3, the front end of the lamp 41 and the faucet part 20 (hole part 12) are located at substantially the same height. Thereby, it is possible to irradiate the water stored in the container part 10 with ultraviolet rays directly and substantially uniformly.

  The lamp 41 emits not only ultraviolet rays but also weak blue light. The blue light is emitted to the outside through the window portion 80. Thereby, the user of the water feeder 1 can determine whether or not the ultraviolet ray is irradiated by looking at the window 80. The light from the LED that emits ultraviolet light also appears blue.

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

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

  The lamp 41 and the cover 42 are immersed in the stored water when water is stored in the container unit 10. For example, when a predetermined amount of water (for example, 8 L) is stored, at least half of the lamp 41 is submerged. For this reason, the lamp 41 and the cover 42 are preferably waterproof.

  In addition, when the ultraviolet light source part 40 irradiates an ultraviolet-ray, the water feeder 1 is normally installed and fixed on a desk or a floor. Therefore, the water stored in the container part 10 is not water (running water) but still water. Since the ultraviolet light source unit 40 irradiates still water with ultraviolet rays, it can be sufficiently sterilized in a short period of time.

[Open / close sensor section]
The open / close sensor unit 50 detects whether or not the opening 11 is blocked by the lid 30. That is, the open / close sensor unit 50 detects whether the lid 30 is in a closed state or an open state.

  As shown in FIGS. 4 and 5, the open / close sensor unit 50 includes a lid-side sensor 51 and a container-side sensor 52. The lid side sensor 51 is built in the lid part 30, for example. The container side sensor 52 is built in the container part 10, for example.

  In the present embodiment, the lid side sensor 51 and the container side sensor 52 are provided so as to be close to each other when the lid portion 30 is closed. For example, the lid-side sensor 51 and the container-side sensor 52 overlap in a 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 container side sensor 52 is a magnet such as a permanent magnet, for example. When the lid 30 is closed, the reed switch of the lid-side sensor 51 is turned on and current flows. The lid-side sensor 51 outputs the current to the drive circuit unit 60 as a detection signal.

  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 output a current that flows when the lid-side sensor 51 approaches the container-side sensor 52 to the drive circuit unit 60 as a detection signal.

[Drive circuit section]
The drive circuit unit 60 controls turning on and off of the ultraviolet light source unit 40. Specifically, the drive circuit unit 60 controls the timing for turning on and off the ultraviolet light source unit 40. Note that the drive circuit unit 60 may perform control to change the intensity of the ultraviolet rays emitted from the ultraviolet light source unit 40 or the period of irradiation with ultraviolet rays.

  In the present embodiment, the drive circuit unit 60 executes a lighting enable mode in which the ultraviolet light source unit 40 can be turned on and a lighting prohibited mode in which the ultraviolet light source unit 40 is prohibited from being turned on. In the lighting enabled mode, the drive circuit unit 60 turns on the ultraviolet light source unit 40 when the power switch 91 of the display panel 90 is pressed. In the lighting prohibition mode, even if the power switch 91 is pressed, the drive circuit unit 60 does not turn on the ultraviolet light source unit 40. The drive circuit unit 60 switches between the lighting enabled mode and the lighting prohibited mode based on the detection result by the open / close sensor unit 50.

  Specifically, the drive circuit unit 60 prohibits the ultraviolet light source unit 40 from being turned on when the opening / closing sensor unit 50 does not detect that the opening 11 is blocked. That is, the drive circuit unit 60 executes the lighting prohibition mode when the lid unit 30 is opened. Specifically, supply of power to the ultraviolet light source unit 40 is prohibited. In addition, the drive circuit unit 60 executes the lighting enabled mode only when the lid unit 30 is closed. Specifically, the drive circuit unit 60 can supply power to the ultraviolet light source unit 40. In addition, 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 a lighting inhibition mode.

  In the present embodiment, for example, when the power switch 91 is pressed in the lighting enabled mode, the drive circuit unit 60 is a lamp of the ultraviolet light source unit 40 for a preset period (hereinafter referred to as “set time”). 41 is turned on. The set time is, for example, 3 minutes, but is not limited to this.

  The drive circuit unit 60 also includes a display control circuit that controls the operation of the indicator 70. The display control circuit controls the lighting display of the indicator 70 according to the state of the water feeder 1. The display control circuit includes, for example, a counter circuit that counts the number of times the lamp 41 is used (number of times of lighting) and stores the counted number of times used. Further, for example, the display control circuit determines whether or not the power supplied from the outside to the drive circuit unit 60 is within a predetermined range when the external power supply and the water supply 1 are connected via a plug. To do. Specifically, the display control circuit determines whether or not the supplied power is within a range that can be used for lighting the lamp 41.

  6 to 8 are a perspective view, a side view, and a front view, respectively, of the drive circuit unit 60 according to the present embodiment. As illustrated in FIG. 7, the drive circuit unit 60 includes a substrate 61 and one or more circuit components 62. 3, 6, 8, etc. do not show one or more circuit components 62.

  As shown in FIG. 3, the substrate 61 is disposed inside the lid portion 30. The substrate 61 is a printed substrate (PCB substrate) in which a metal wiring such as a copper foil is patterned on one surface (solder surface). One or more circuit components 62 are electrically connected by metal wiring patterned on the substrate 61. The metal wiring is electrically connected to the lamp 41 of the ultraviolet light source unit 40 by a cable such as a lead wire.

  As shown in FIGS. 6 and 8, the substrate 61 includes a main mounting portion 61a and a sub mounting portion 61b. The main mounting portion 61a is a flat plate portion having a substantially rectangular shape in plan view in which the upper two corners are substantially arcs. Main circuit components 62 such as a microcomputer and an inverter for turning on the ultraviolet light source unit 40 are mounted on the main mounting portion 61a. The one or more circuit components 62 include a microcomputer (microcontroller or microcomputer), an inverter, a resistance element, a capacitor, an inductor, a rectifying element, and the like.

  The sub mounting portion 61b is a substantially rectangular flat plate portion provided so as to protrude upward from the upper end surface of the main mounting portion 61a. The sub mounting portion 61b includes a switch mounting portion 61c, a first LED mounting portion 61d, and a second LED mounting portion 61e that are separated by two recesses. In the present embodiment, the switch mounting portion 61c is provided between the first LED mounting portion 61d and the second LED mounting portion 61e.

  The switch mounting portion 61c is a portion where the switch element 63 is mounted. The switch element 63 is one of the circuit components 62 and is a pressing operation type switch element for starting lighting of the ultraviolet light source unit 40. As shown in FIG. 7, the switch element 63 has a main body 63a and a pressed part 63b. When the pressed portion 63b is pushed downward toward the main body 63a, the switch element 63 outputs a control signal for starting the lamp 41. Specifically, the pressed portion 63b is pushed downward in conjunction with the power switch 91 of the display panel 90 being pushed.

  In the present embodiment, as shown in FIG. 7, the switch element 63 is disposed so that the pressed portion 63 b protrudes above the upper end of the substrate 61. Thereby, it is possible to easily push down the pressed portion 63b by applying a force from above.

  The first LED mounting portion 61d is a portion where the two light emitting elements 71 and 72 are mounted. The two light emitting elements 71 and 72 are part of the indicator 70. The two light emitting elements 71 and 72 are an example of a solid light emitting element that is disposed along the upper end of the substrate 61 and emits light upward.

  The second LED mounting portion 61e is a portion where the two light emitting elements 73 and 74 are mounted. The two light emitting elements 73 and 74 are part of the indicator 70. The two light emitting elements 73 and 74 are an example of a solid state light emitting element that is disposed along the upper end of the substrate 61 and emits light upward.

  In the present embodiment, as shown in FIG. 7, the surface on which the four light emitting elements 71 to 74 are mounted is the surface opposite to the surface on which the switch element 63 is mounted. As shown in FIG. 2, the four light emitting elements 71 to 74 are arranged on a straight line in a top view.

  In the present embodiment, the substrate 61 is inclined with respect to the bottom surface of the container part 10 when the lid part 30 is attached to the container part 10. Specifically, the substrate 61 is disposed along a direction orthogonal to the bottom surface of the container unit 10 when the lid unit 30 is attached to the container unit 10.

  For example, when the water feeder 1 places the bottom surface of the container unit 10 on a horizontal plane, the substrate 61 is inclined with respect to the horizontal plane. For example, the substrate 61 is inclined at an inclination angle of 45 ° or more with respect to the horizontal plane. Thereby, even when a liquid such as water adheres to the substrate 61, the liquid flows along the inclination, so that a short circuit of the circuit due to the liquid can be suppressed.

  In the present embodiment, the substrate 61 is disposed (vertically placed) at a substantially right angle to the horizontal plane (that is, along the vertical direction). Thereby, even when the liquid enters the inside of the lid 30 from the upper surface of the lid 30, the substrate 61 is arranged vertically, and thus it is difficult to hit the substrate 61 when the liquid falls. Therefore, it is possible to suppress a short circuit of the circuit due to the liquid.

  In the present embodiment, as shown in FIG. 9, the substrate 61 is fixed to the upper inner surface of the lid 30. FIG. 9 is an enlarged cross-sectional view showing the vicinity of the drive circuit unit 60 of the water feeder 1 according to the present embodiment. Specifically, FIG. 9 shows a cross section corresponding to the line IX-IX in FIG.

  As shown in FIG. 9, the surface portion 31 of the lid portion 30 has a plurality of bosses 34. Each of the plurality of bosses 34 is provided so as to protrude downward from the inner surface of the surface portion 31, and is provided with a screw hole 34a at the tip.

  As shown in FIG. 8, the main mounting portion 61a of the substrate 61 is provided with two through holes 61f. As shown in FIGS. 9 and 10, a holding metal fitting 64 is inserted into each of the two through holes 61 f. Here, FIG. 10 is a cross-sectional view showing a cross section of the substrate 61 and the presser fitting 64 taken along the line XX of FIG. For ease of explanation, FIG. 10 does not show the configuration other than the substrate 61 and the presser fitting 64.

  The holding metal fitting 64 is, for example, an 8-shaped holding metal fitting having two screw holes 64a. Alternatively, the presser fitting 64 may be a plate-shaped metal member having screw holes formed at both ends.

  The presser fitting 64 is inserted into the through hole 61f, and the board 61 is inserted into the screw hole 64a of the presser fitting 64 and the screw hole 34a of the boss 34 as shown in FIG. Is pressed upward and fixed. Since the board | substrate 61 is located between the two boss | hubs 34, it can maintain the attitude | position substantially orthogonal to a horizontal surface stably.

  Further, in the present embodiment, as shown in FIG. 9, the substrate 61 is not in contact with the back surface portion 32 of the lid portion 30. That is, a gap is formed between the substrate 61 and the back surface portion 32. Thereby, even if a liquid such as water enters the inside of the lid portion 30 and accumulates on the back surface portion 32, the substrate 61 is less likely to come into contact with the liquid. Therefore, a short circuit of the drive circuit unit 60 can be suppressed.

  In the present embodiment, as shown in FIG. 7, the switch element 63 and the light emitting elements 71 to 74 of the indicator 70 are also mounted on one substrate 61. That is, the circuit board disposed inside the lid 30 is only the board 61. Thereby, the storage space inside the lid part 30 can be used effectively. Or since the internal space of the cover part 30 can be made small, thickness reduction and weight reduction of the cover part 30 are realizable.

[indicator]
The indicator 70 displays information related to the state of the water feeder 1. The indicator 70 includes a plurality of light emitting elements. The plurality of light emitting elements include a first light emitting element and a second light emitting element having different emission wavelengths. In the present embodiment, as shown in FIG. 2, the indicator 70 includes four light emitting elements 71 to 74.

  The four light emitting elements 71 to 74 are solid light emitting elements such as LEDs that emit visible light. In the present embodiment, the light emitting element 71 and the light emitting element 73 are an example of a first light emitting element, and emit red light. The light emitting element 72 and the light emitting element 74 are an example of a second light emitting element, and emit green light.

  In the present embodiment, as shown in FIG. 6, the four light emitting elements 71 to 74 are arranged in a straight line with the switch element 63 sandwiched in the center. The two light emitting elements 71 and 72 mainly indicate information on the power source, and the two light emitting elements 73 and 74 mainly indicate information on the lamp 41.

  Note that the number and arrangement of the light emitting elements included in the indicator 70 and the respective emission wavelengths (light emission colors) are not limited to these. For example, the indicator 70 may include only two light emitting elements or may include five or more light emitting elements. Further, the four light emitting elements 71 to 74 may be arranged not in a straight line but in a matrix of 2 rows and 2 columns. The four light emitting elements 71 to 74 may have the same emission wavelength, or may have different emission wavelengths.

  The four light emitting elements 71 to 74 display a plurality of pieces of information according to combinations of lighting / lighting modes. The mode of turning on / off includes continuous lighting, blinking lighting, and extinguishing. Continuous lighting is a state in which lighting at a predetermined luminance is continuous (continuous). Blinking lighting is a state in which high luminance and low luminance (or extinction) are periodically repeated. Off is a state in which the light is not lit (luminance is 0).

  The four light emitting elements 71 to 74 are controlled by a display control circuit provided in the drive circuit unit 60. Each of the four light emitting elements 71 to 74 is individually controlled to be turned on / off by the display control circuit.

  The plurality of pieces of information displayed by the four light emitting elements 71 to 74 include sterilization information relating to the sterilization state of the liquid by the ultraviolet light source unit 40 and life information relating to the lifetime of the ultraviolet light source unit 40. In the present embodiment, the plurality of information further includes power information related to power supplied to the drive circuit unit 60 from the outside, open / close information related to the open / closed state of the opening 11 by the lid 30, and the operation of the ultraviolet light source unit 40. Contains operational information about the state.

  FIG. 11 is a diagram illustrating a correspondence relationship between the lighting / extinguishing mode of the four light emitting elements 71 to 74 and the state of the water supply device 1 according to the present embodiment. As shown in FIG. 11, the plurality of light emitting elements 71 to 74 are turned on or off in a manner corresponding to the state of the water supply 1 when a user operation is performed.

  (I) When the user opens the lid part 30, that is, when the lid part 30 is removed from the container part 10, all the four light emitting elements 71 to 74 are turned off.

  (Ii) When the user pours water into the container part 10 through the opening part 11, all the four light emitting elements 71 to 74 are turned off.

  (Iii) When the user connects the plug to the lid 30, specifically, when power is supplied to the drive circuit unit 60, the four light emitting elements 71 to 74 display power information. The power information includes information indicating that the supplied power is normal (the lamp 41 can be turned on) and the supplied power is abnormal (the lamp 41 cannot be turned on). Is included. Each of the four light emitting elements 71 to 74 is turned on or off in a manner associated with the power information (supplied power state).

  Specifically, (a) when the supplied power is normal, all the four light emitting elements 71 to 74 are turned off. (B) When the supplied power is abnormal, the light emitting element 71 blinks red light and the light emitting elements 72 to 74 are turned off.

  (Iv) When the user closes the lid part 30, that is, when the lid part 30 is attached to the container part 10, the four light emitting elements 71 to 74 display opening / closing information. The opening / closing information includes information indicating that the lid portion 30 is completely closed and information indicating that the lid portion 30 is incompletely closed. Each of the four light emitting elements 71 to 74 is turned on or off in a manner associated with opening / closing information (opening / closing state of the lid 30).

  Specifically, (a) When the lid portion 30 is completely closed, the light emitting element 72 is continuously lit with green light, and the light emitting elements 71, 73, and 74 are turned off. This state corresponds to a standby state in which ultraviolet light can be irradiated when the power switch 91 is pressed. That is, the drive circuit unit 60 is executing the lighting enable mode.

  (B) When the lid portion 30 is incompletely closed, the light emitting element 72 blinks green light and the light emitting elements 71, 73, and 74 are turned off. This state is a state in which ultraviolet light cannot be irradiated even when the power switch 91 is pressed. That is, the drive circuit unit 60 is executing the lighting prohibition mode.

  (V) When the power switch 91 is pressed, the four light emitting elements 71 to 74 display operation information. The operation information includes information indicating that the lamp 41 of the ultraviolet light source unit 40 is lit and information indicating that the lamp 41 is not lit. Each of the four light emitting elements 71 to 74 is turned on or off in a manner associated with the operation information (the operation state of the ultraviolet light source unit 40).

  Specifically, (a) when the lamp 41 is lit, the light emitting element 72 continuously lights green light, and the light emitting element 74 blinks green light. The light emitting elements 71 and 73 are turned off. (B) When the lamp 41 is not turned on, the light emitting element 72 continuously lights green light, and the light emitting element 73 blinks red light. The light emitting elements 71 and 74 are turned off.

  (Vi) When the user is on standby, that is, during a period in which the user leaves the water supply 1 after pressing the power switch 91, the four light emitting elements 71 to 74 display sterilization information. The sterilization information includes information indicating that the liquid has not been sterilized, information indicating that the liquid is being sterilized, and information indicating that the liquid has been sterilized. Each of the four light emitting elements 71 to 74 is turned on or off in a manner associated with sterilization information (liquid sterilization state).

  Specifically, (a) When the liquid is being sterilized, the light emitting element 72 continuously lights green light, and the light emitting element 74 blinks green light. The light emitting elements 71 and 73 are turned off. (B) When the process is stopped before the sterilization is completed, all the four light emitting elements 71 to 74 are turned off. For example, when power is not supplied due to a power failure or plug disconnection, or when the lamp 41 or the drive circuit unit 60 breaks down, the processing is stopped. At this time, the sterilization of the liquid is not completed.

  (Vii) When the sterilization is completed when the user confirms the state of the water dispenser 1 after a predetermined period of time has elapsed since the user pressed the power switch 91, the light emitting elements 72 and 74 continuously light green light, and the light emitting element 71 and 73 are turned off.

  As described above, in the example illustrated in FIG. 11, eight patterns (11 patterns including overlapping) are illustrated as combinations of the on / off modes of the four light emitting elements 71 to 74. Thereby, indicator 70 (four light emitting elements 71-74) displays eight information.

  For example, when the light emitting element 71 blinks and the light emitting elements 72 to 74 are turned off ((iii) (a) in FIG. 11), the user knows that the supplied power is abnormal. it can. When the light emitting element 72 is continuously turned on and the light emitting elements 71, 73 and 74 are turned off ((iv) (a) in FIG. 11), the user has completely closed the lid 30. It can be seen that the water supply 1 is in a standby state.

  When all of the four light emitting elements 71 to 74 are turned off, (i) when the lid 30 is opened, (ii) when the user is injecting water, (iii) ( a) When normal power is supplied to the drive circuit unit 60, four states can be considered when the process (b) of (vi) is stopped halfway. In either case, the liquid is unsterilized.

  That is, when all the four light emitting elements 71 to 74 are turned off, the user can know that the liquid is not sterilized. Therefore, it is possible to refrain from using the liquid stored in the container part 10 as it is. On the other hand, when the light emitting elements 72 and 74 are continuously turned on and the light emitting elements 71 and 73 are turned off, the user can know that the liquid has been sterilized.

  As described above, the user can know the sterilization state of the liquid and the like by confirming the mode of turning on and off the four light emitting elements 71 to 74.

  In the present embodiment, the four light emitting elements 71 to 74 further display life information on the life of the ultraviolet light source unit 40. The lamp 41 of the ultraviolet light source unit 40 has a lifetime. That is, the lamp 41 has an upper limit on the number of times it can be used to obtain a sufficient sterilizing effect. The lifetime information includes information indicating that the number of times the ultraviolet light source unit 40 is used (the number of times the lamp 41 is turned on) is greater than a predetermined first number (specifically, the upper limit of the number of times used), and the number of times used. , Information indicating that it is greater than or equal to the second number of times and less than or equal to the first number of times is included. The second number is a number smaller than the first number and is a number for making a notice of the life.

  FIG. 12 is a diagram illustrating the relationship between the lighting / light-off mode of the four light emitting elements 71 to 74 according to the present embodiment and the lifetime of the ultraviolet light source unit 40. As shown in FIG. 12, the four light emitting elements 71 to 74 are turned on or off in a manner associated with the life information (the number of times the lamp 41 is used). Below, the case where the lifetime (namely, upper limit of the number of use) of the lamp | ramp 41 is 4000 times is demonstrated as an example.

  The four light emitting elements 71 to 74 display life information when electric power is supplied to the drive circuit unit 60 from the outside. Specifically, when the number of uses is 0 times or more and 3940 times or less, all the four light emitting elements 71 to 74 are turned off. In this case, since there is a sufficient margin in the number of times of use until the life of the lamp 41, it is not necessary to inform the user. Therefore, as shown in FIG. 11, the four light emitting elements 71 to 74 are turned on and off in the same manner as in the state where the liquid is not sterilized.

  When the number of uses is 3941 times (an example of the second number of times) or more and 4000 times or less, the light emitting elements 71 and 73 blink red and the light emitting elements 72 and 74 are off. The number of blinks in blinking lighting is, for example, 3 to 5 times. Thereby, the user can know that the lifetime of the lamp 41 is near. As described above, the four light emitting elements 71 to 74 notify the lamp 41 of the service life, so that the user can take measures against the lamp burnout such as lamp replacement.

  When the number of uses is more than 4000, the light emitting elements 71 and 73 are continuously lit with red light, and the light emitting elements 72 and 74 are off. Thereby, since the user can know that the life of the lamp 41 has expired, the user can know that the liquid may not be sufficiently sterilized.

  In this way, the four light emitting elements 71 to 74 display the life information, so that the user can take measures such as lamp replacement.

  As described above, in the indicator 70 according to the present embodiment, the four light emitting elements 71 to 74 can indicate information more than the number of light emitting elements.

  Accordingly, the number of light emitting elements used as the indicator 70 can be reduced, so that the size of the display control circuit can be reduced. Further, since the area necessary for the arrangement of the light emitting elements is reduced, the space can be used effectively. In addition, since the number of light emitting elements is small, the heat dissipation design is facilitated. The power consumption can be reduced by appropriately combining the lighting-off modes of a small number of light-emitting elements. Moreover, since the number of parts decreases, the manufacturing cost of the water feeder 1 can be reduced.

  Note that the information displayed by the four light emitting elements 71 to 74 is not limited to the information shown in FIGS. 11 and 12. For example, the four light emitting elements 71 to 74 may display information according to the amount of liquid stored in the container unit 10. Specifically, the four light emitting elements 71 to 74 can prompt the user to replenish the liquid by emitting light in a predetermined manner when the amount of the liquid is less than the predetermined amount.

[Window]
The window part 80 contains the wavelength conversion material which converts an ultraviolet-ray into visible light. In the present embodiment, the window portion 80 is provided on the lid portion 30. The window part 80 is provided in order to confirm whether the ultraviolet light source part 40 in the container part 10 is irradiating with an ultraviolet-ray.

  FIG. 13 is a cross-sectional view of the water feeder 1 according to the present embodiment, showing an enlarged portion surrounded by a broken line XIII in FIG. 3. Specifically, FIG. 13 shows a cross section of the window 80. FIG. 14 is a diagram illustrating an example of light that passes through the window 80 of the water feeder 1 according to the present embodiment.

  In the present embodiment, as shown in FIG. 13, the window 80 includes a hole 81, a cover member 82, a translucent member 83, and a reflecting member 84.

  The hole portion 81 penetrates the lid portion 30 in the direction (z-axis direction) from the front surface to the back surface. The hole 81 may be filled with a light-transmitting resin material or glass material. In the present embodiment, the opening shape of the hole 81 (corresponding to the plan view shape of the cover member 82) is substantially rectangular as shown in FIG. 2, but is not limited thereto. The opening shape of the hole 81 may be circular or elliptical.

  As shown in FIG. 13, the hole portion 81 is formed by extending a part of the back surface portion 32 of the lid portion 30 toward the front surface portion 31 in a cylindrical shape. Alternatively, the hole portion 81 may be formed by extending a part of the front surface portion 31 toward the back surface portion 32 in a cylindrical shape. Further, the hole 81 may be formed separately from the lid 30.

The cover member 82 is provided in the opening outside the hole 81. The cover member 82 contains a plurality of wavelength conversion materials inside. Specifically, the plurality of wavelength conversion materials are a plurality of phosphors (phosphor particles). The phosphor converts ultraviolet light into green light. As the wavelength converting material, for example, a LAP phosphor (cerium, terbium activated lanthanum phosphate phosphor; LaPO ₄ : Ce ³⁺ , Tb ³⁺ ) can be used, and the LAP phosphor receives ultraviolet rays having a wavelength of 300 nm or less. In this case, fluorescence (green light) having a peak wavelength at about 550 nm is emitted. Since green light is light with high visibility for humans, it is possible to easily confirm the irradiation state of ultraviolet rays.

  As shown in FIG. 13, the cover member 82 includes a wavelength conversion part 82 a that contains a plurality of wavelength conversion materials and a transmission part 82 b that does not contain a wavelength conversion material.

  The wavelength conversion part 82a is formed in an annular shape so as to surround the transmission part 82b. In the present embodiment, as shown in FIG. 2, the planar view shape of the wavelength conversion unit 82a is a rectangular ring shape. The arrangement and shape of the wavelength conversion unit 82a and the transmission unit 82b in plan view are not limited to these. For example, a wavelength conversion unit 82a having a rectangular shape in plan view and a transmission portion 82b having a rectangular shape in plan view may be arranged side by side.

  The wavelength conversion part 82a is formed by dispersing a plurality of phosphor particles in a predetermined region of a plate-like glass material or resin material. As a result, as shown in FIG. 14, the UV light UV3 is absorbed by the transmission part 82b, whereas the UV light UV1 and UV2 are irradiated to the phosphor particles by the wavelength conversion part 82a. The phosphor particles are excited by ultraviolet rays UV1 and UV2 to emit green light GL1 and GL2.

  For example, the cover member 82 is formed of a glass plate that blocks ultraviolet rays, and in the wavelength conversion unit 82a, the glass plate is formed thinner than the transmission unit 82b, and a plurality of phosphor particles are dispersed therein. It may be. The wavelength conversion part 82a and the transmission part 82b may be formed separately.

  The transmission part 82b blocks ultraviolet rays and transmits visible light. Thereby, the inside of the container part 10 can be seen from the outside through the transmission part 82b. As described above, the ultraviolet light source unit 40 emits blue light although it is weak when it is irradiated with ultraviolet rays. As shown in FIG. 14, the emitted blue lights BL1 and BL2 are transmitted through the transmission part 82b and emitted to the outside. When the ultraviolet light source unit 40 is turned on, the blue lights BL1 and BL2 can be confirmed when looking into the interior of the container unit 10 through the transmission unit 82b.

  The cover member 82 may include diffusing particles that diffuse (scatter) visible light. Thereby, the light emission of the window part 80 (cover member 82) can be confirmed not only from the direction directly above the window part 80 but also from a distant position such as obliquely above. Note that visible light may be diffused by forming irregularities on the surface of the cover member 82. The unevenness can be formed by, for example, embossing.

  The translucent member 83 transmits ultraviolet light and blue light emitted from the ultraviolet light source unit 40. The translucent member 83 is provided in the opening inside the hole 81 on the back surface of the lid 30. The translucent member 83 is made of, for example, a glass material. The translucent member 83 suppresses the liquid stored in the container part 10 from entering the hole part 81. Thereby, it can suppress that a liquid contacts the drive circuit part 60 arrange | positioned inside the cover part 30. FIG.

  The reflection member 84 reflects ultraviolet light and blue light emitted from the ultraviolet light source unit 40. For example, FIG. 14 shows an example in which the ultraviolet light UV <b> 2 is reflected by the reflecting member 84. The reflecting member 84 is provided along the side surface of the hole 81. Thereby, the reflection member 84 can suppress the ultraviolet light and blue light passing through the hole 81 from being absorbed by the lid 30. The reflecting member 84 is, for example, a metal film such as aluminum.

  In the present embodiment, the window portion 80 is provided so as to penetrate the lid portion 30, but is not limited thereto. The window part 80 may be provided so as to penetrate the container part 10. Specifically, the hole part 81 may penetrate the outer wall of the container part 10. For example, the lamp 41 of the ultraviolet light source unit 40 can be directly confirmed by providing the window 80 on the side wall of the container unit 10.

[Display panel]
The display panel 90 is a panel (decorative plate) provided on the upper surface of the lid 30. The display panel 90 is provided so as to cover a region including the switch element 63, the indicator 70, and the window portion 80 of the drive circuit unit 60 in plan view. Specifically, the display panel 90 has openings corresponding to the light emitting elements 71 to 74 and the window part 80, and allows light from the light emitting elements 71 to 74 and the window part 80 to pass therethrough.

  The display panel 90 has a power switch 91 at a position corresponding to the switch element 63. The power switch 91 is a push button switch. When the power switch 91 is pressed, the pressed portion 63b of the switch element 63 is pressed down. Thereby, when the drive circuit unit 60 is in the lightable mode, when the power switch 91 is pressed, the ultraviolet light source unit 40 starts irradiating ultraviolet rays, and the liquid is sterilized.

[Effects, etc.]
As described above, the water feeder 1 according to the present embodiment has the opening 11 for injecting liquid therein, the container 10 for storing the liquid, and the container for closing the opening 11. A lid 30 that can be attached to and detached from the unit 10; an ultraviolet light source unit 40 that is disposed inside the container unit 10 and sterilizes the liquid by irradiating the liquid stored in the container unit 10 with ultraviolet rays; and the ultraviolet light source unit 40 A drive circuit unit 60 that controls lighting and extinction. The driving circuit unit 60 includes a substrate 61 disposed inside the lid unit 30 and a substrate 61 for controlling lighting and extinction of the ultraviolet light source unit 40. One or more circuit components 62 are mounted, and the substrate 61 is inclined with respect to the bottom surface of the container 10 when the lid 30 is attached to the container 10.

  Thereby, since the substrate 61 is inclined, even if the liquid that has entered the inside of the lid portion 30 is applied to the substrate 61, the liquid easily flows down along the inclination. Therefore, a short circuit of the drive circuit unit 60 can be suppressed.

  For example, the board | substrate 61 is being fixed to the upper inner surface of the cover part 30. FIG.

  Thereby, a gap can be formed between the substrate 61 and the lower inner surface of the lid portion 30. Even if the liquid enters the lid portion 30 and accumulates on the lower inner surface, the substrate 61 is less likely to come into contact with the liquid. Therefore, a short circuit of the drive circuit unit 60 can be suppressed.

  For example, the substrate 61 is disposed along a direction orthogonal to the bottom surface of the container unit 10 when the lid unit 30 is attached to the container unit 10.

  Thereby, since the substrate 61 is arranged vertically, it is difficult to hit the substrate 61 when the liquid that has entered from the upper surface of the lid 30 falls. Therefore, a short circuit of the drive circuit unit 60 can be suppressed.

  Further, for example, the water supply device 1 further includes an indicator 70 that indicates the sterilization state of the liquid by the ultraviolet light source unit 40, and the indicator 70 is disposed along the upper end of the substrate 61 and emits light upward. The light emitting elements 71 to 74 are included.

  Thereby, since the light emitting elements 71 to 74 included in the indicator 70 are mounted on one substrate 61, the storage space inside the lid 30 can be used effectively. Or since the internal space of the cover part 30 can be made small, thickness reduction and weight reduction of the cover part 30 are realizable.

  Further, for example, the one or more circuit components 62 include a pressing operation type switch element 63 for starting the lighting of the ultraviolet light source unit 40, and the pressed part 63 b of the switch element 63 is from the upper end of the substrate 61. It is arranged so as to protrude upward.

  As a result, the pressed portion 63b of the switch element 63 can be easily pushed downward.

  In addition, for example, the water feeder 1 further includes a water tap part 20 for supplying the liquid stored in the container part 10.

  Thereby, the liquid stored inside can be easily taken out outside. Specifically, since the liquid can be taken out without opening the lid portion 30, bacteria and the like can be prevented from entering the container portion 10.

(Modification 1)
Below, the modification 1 of the water feeder 1 which concerns on said embodiment is demonstrated.

  FIG. 15 is a schematic perspective view of a water supply device 101 according to this modification. As shown in FIG. 15, the water supply device 101 according to this modification is different from the water supply device 1 according to the first embodiment in that an information display unit 195 is further provided, and the other configurations are the same. It is. For this reason, in the following description, it demonstrates focusing on a different point from embodiment, and the description of the same point is abbreviate | omitted or simplified.

  The information display unit 195 displays a combination of lighting / light-off modes of each of the four light emitting elements 71 to 74 included in the indicator 70 and a plurality of pieces of information meaning the combination. Specifically, the information display unit 195 presents to the user the correspondence between the lighting and extinguishing modes illustrated in FIGS. 11 and 12 and the state of the water supply 101.

  As shown in FIG. 15, the information display unit 195 is attached to the outer surface of the container unit 10. For example, the information display unit 195 is a sealing material on which the tables shown in FIGS. 11 and 12 are printed. The information display unit 195 may be attached to the outer surface of the lid unit 30.

  In this modification, as shown in FIGS. 11 and 12, four light emitting elements 71 to 74 represent 11 patterns (14 patterns unless overlapping is included). In this way, since a small number of light emitting elements represent a state equal to or greater than the number of light emitting elements, it may be difficult to determine which lighting state and what state is represented.

  On the other hand, according to the water supply device 101 according to this modification, the information display unit 195 is attached to the outer surface of the container unit 10 or the lid unit 30, so that the user has a plurality of light emitting elements 71 to 74. It is possible to easily grasp what information is displayed. Thereby, user convenience can be improved.

(Modification 2)
Below, the modification 2 of the water feeder 1 which concerns on said embodiment is demonstrated.

  FIG. 16 is a cross-sectional view of a water supply device 102 according to this modification. As shown in FIG. 16, the water supply 102 which concerns on this modification differs in the point provided with the window part 180 instead of the window part 80 compared with the water supply 1 which concerns on embodiment, and another structure Are the same. For this reason, in the following description, it demonstrates focusing on a different point from embodiment, and the description of the same point is abbreviate | omitted or simplified.

  FIG. 17 is a cross-sectional view of the water feeder 1 according to the embodiment, showing an enlarged portion surrounded by a broken line XVII in FIG. 16. As shown in FIG. 17, the window portion 180 has a shutter portion 185.

  The shutter unit 185 is an openable / closable light-blocking shutter unit provided on the light emitting side of the cover member 82. Specifically, the shutter unit 185 blocks visible light. For example, the shutter unit 185 is formed using a light-blocking resin material such as polypropylene, like the lid unit 30.

  In this modification, the shutter unit 185 is a slide type. FIG. 18 is a cross-sectional view showing the window portion 180 in a state where the shutter portion 185 according to this modification is opened. As shown in FIGS. 17 and 18, the shutter portion 185 is slidable on the upper surface of the cover member 82 and the upper surface of the surface portion 31 of the lid portion 30.

  Note that the state in which the shutter unit 185 is opened means a state in which the shutter unit 185 does not cover the cover member 82 and the cover member 82 is visible from the outside, as shown in FIG. Conversely, the state in which the shutter unit 185 is closed means a state in which the shutter unit 185 covers and covers the cover member 82 as shown in FIG. 17, and the cover member 82 is not visible from the outside.

  The window part 180 further includes restriction parts 187 and 189.

  The restricting portion 187 is located at a position that covers the upper surface of the shutter portion 185 with the shutter portion 185 opened. That is, as shown in FIG. 17, the regulating portion 187 forms a space 188 for accommodating the shutter portion 185 between the upper surface of the lid portion 30. As shown in FIG. 18, in a state where the shutter unit 185 is opened, the regulating unit 187 covers the upper surface of the shutter unit 185, so that the shutter unit 185 can be prevented from being detached from the lid unit 30.

  The restriction part 189 is a part that restricts the sliding of the shutter part 185 when the shutter part 185 is closed. In the present modification, the restricting portion 189 is an end portion of the display panel 90.

  As shown in FIG. 17, when the shutter unit 185 is closed, the tip of the shutter unit 185 comes into contact with the regulating unit 189. At this time, the other end of the shutter portion 185 is covered with the restricting portion 187. Thereby, detachment of the shutter portion 185 can be suppressed even in a state where the shutter portion 185 is closed, and light from the window portion 80 can be blocked more reliably.

  As shown in FIGS. 17 and 18, the shutter portion 185 has a convex portion 186. Thereby, the user can slide the shutter part 185 easily by pushing the convex part 186 in the sliding direction. The convex part 186 protrudes upward from the restricting part 187, for example. Thereby, even if the shutter part 185 is in the opened state, the convex part 186 can be easily pushed, so that the shutter part 185 can be easily opened and closed.

  As described above, according to the water supply device 102 according to the present modification, for example, the window portion 180 further includes the openable / closable light-shielding shutter portion 185 provided on the light emitting side of the cover member 82.

  As a result, for the user who does not wish to confirm the irradiation of the ultraviolet light by visual observation, the light emission of the window portion 180 can be made invisible by closing the shutter portion 185. For example, it is more useful in an environment where light emission from the window 180 is conspicuous, such as when used at night.

  In this modification, an example in which the shutter unit 185 is a slide type has been described, but the present invention is not limited to this. The shutter unit 185 may be a lid whose end is fixed to the surface unit 31 via a hinge or the like so as to be opened and closed. Alternatively, the shutter unit 185 may be a removable lid.

(Embodiment 2)
In the first embodiment and the modification, the stationary type so-called water jug has been described as an example, but the present invention is not limited thereto. For example, the sterilization container according to the present invention can be realized as a portable mug.

  FIG. 19 is a schematic perspective view of the lidded mug 201 according to the present embodiment. FIG. 20 is a schematic perspective view showing a state in which the lid portion 230 of the lidded mug 201 according to the present embodiment is removed.

  The lidded mug 201 is a portable container (so-called water bottle) for storing a liquid. The lid-equipped mug 201 sterilizes the liquid by irradiating the liquid with ultraviolet rays (UV light), like the water feeder 1 according to the first embodiment. As shown in FIG. 19, the lidded mug 201 includes a container part 210, a lid part 230, an ultraviolet light source part 240, a window part 280, and a display panel 290.

  The container part 210 is a bottomed cylindrical container for storing a liquid. The container part 210 has an opening 211 for injecting liquid into the internal space. An unsterilized liquid such as tap water is injected into the container part 210 through the opening 211, and the injected unsterilized liquid is stored. The stored unsterilized liquid is irradiated with ultraviolet rays by the ultraviolet light source unit 240 and then supplied (discharged) to the outside through the opening 211. That is, in the present embodiment, the opening 211 serves as both a liquid injection port and a supply port. Specifically, the opening 211 also serves as a drinking mouth.

  The capacity of the internal space of the container part 210 is, for example, 500 mL, but is not limited to this. The container part 210 is, for example, large enough to be held by one person with one hand or both hands.

  The lid part 230 is a detachable lid for the container part 210 for closing the opening part 211. The lid part 230 seals the internal space of the container part 210 by closing the opening part 211. As shown in FIG. 19, an ultraviolet light source unit 240 is attached to the back surface of the lid unit 230. As shown in FIG. 20, a drive circuit unit 260 is disposed inside the lid unit 230.

  The lidded mug 201 according to the present embodiment is carried by a user and is used outdoors where it is not possible to obtain external power supply. For this reason, a battery (not shown) is provided inside the lid portion 230. The battery is, for example, a primary battery or a secondary battery.

  The ultraviolet light source unit 240 has the same configuration and function as the ultraviolet light source unit 40 according to the first embodiment. The ultraviolet light source unit 240 is miniaturized so as to fit inside the container unit 210 and to be attached to the back surface of the lid unit 230.

  The ultraviolet light source unit 240 is disposed inside the container unit 210 and sterilizes the liquid by irradiating the liquid stored in the container unit 210 with ultraviolet rays. The ultraviolet rays to be irradiated are, for example, ultraviolet rays having a peak wavelength in the range of 200 nm to 400 nm.

  The drive circuit unit 260 has the same configuration and function as the drive circuit unit 60 according to the first embodiment. The drive circuit unit 260 is smaller in size than the drive circuit unit 60 so as to be housed inside the lid unit 230. The drive circuit unit 260 supplies the ultraviolet light source unit 240 with electric power from a battery disposed inside the lid unit 230, not with electric power supplied from the outside.

  The substrate 261 of the drive circuit unit 260 is inclined with respect to the bottom surface of the container unit 210 when the lid unit 230 is attached to the container unit 210 as in the first embodiment. Specifically, the substrate 261 is arranged along a direction orthogonal to the bottom surface (for example, a horizontal plane) of the container unit 210 (so-called vertical placement).

  As shown in FIG. 20, since the upper surface of the lid 230 is a plane, the substrate 261 is orthogonal to the horizontal plane even when the lid 230 is placed upside down. For this reason, even when the lid 230 is placed upside down, the liquid that has entered the lid 230 does not easily hit the substrate 261. Thereby, a short circuit can be suppressed.

  The indicator 270 has the same configuration and function as the indicator 70 according to the first embodiment. Since the lid 230 of the lidded mug 201 has a built-in battery, battery remaining amount information may be displayed. The remaining amount information indicates, for example, information indicating that the battery is sufficiently charged (that is, irradiation with ultraviolet rays is possible) and that the remaining amount is substantially zero (that is, irradiation with ultraviolet rays is not possible). Contains information.

  For example, as shown in FIG. 11, the display when the plug is connected can be applied to the remaining amount information. Specifically, when the battery is sufficiently charged, all the four light emitting elements 71 to 74 are turned off. When the remaining amount of the battery is substantially zero, the light emitting element 71 blinks red light and the light emitting elements 72 to 74 are turned off.

  In the present embodiment, indicator 270 displays life information when power switch 291 is pressed. Specifically, when the power switch 291 is pressed, the indicator 270 displays life information, then displays operation information as in the first embodiment, and then displays sterilization information. In addition, the timing which displays lifetime information is not restricted to this, For example, you may be when the cover part 230 is closed.

  The window unit 280 has the same configuration and function as the window unit 80 according to the first embodiment. The window part 280 contains the wavelength conversion material which converts an ultraviolet-ray into visible light. Thereby, when the ultraviolet ray is lit inside the container part 210, the ultraviolet ray is irradiated to the wavelength conversion material, and visible light (for example, green light) is emitted from the window part 280. That is, since the window part 280 appears to shine green, the user can confirm that the liquid is irradiated with ultraviolet rays by confirming the light emission of the window part 280.

  The display panel 290 has the same configuration and function as the display panel 90 according to the first embodiment. The display panel 290 is smaller than the display panel 90 in accordance with the size of the lid portion 230.

  As described above, the lidded mug 201 according to the present embodiment has the opening 211 for injecting liquid therein, and the container 210 for storing the liquid, and the opening 211 for closing the opening 211, A lid 230 that can be attached to and detached from the container 210, an ultraviolet light source 240 that sterilizes the liquid by irradiating the liquid stored in the container 210 with ultraviolet light, and an ultraviolet light source 240 A drive circuit unit 260 that controls the turning on and off of the light source, and the driving circuit unit 260 controls the turning on and off of the substrate 261 disposed inside the lid 230 and the ultraviolet light source unit 240. And the circuit board 261 is inclined with respect to the bottom surface of the container part 210 when the lid part 230 is attached to the container part 210, and the opening 211 is Drinking Also it serves as a mouth.

  Thereby, similarly to Embodiment 1, since the board | substrate 261 inclines and is arrange | positioned inside the cover part 230, there can exist an effect similar to the water feeder 1 which concerns on Embodiment 1. FIG.
