DETAILED DESCRIPTION

[0069] The present invention relates to a water treatment device which includes a mist generating unit and a control unit for controlling the operation of the mist generating unit and sprays purified water or functional water in a mist form toward the outside of the device.

[0070] In the water treatment device of this embodiment, as a feature thereof, the mist generating unit can at least atomize the purified water purified by the water purification unit and spray it to the surroundings. In addition, the wetting effect of the mist can be given to the user of the water treatment device. Moreover, in the water treatment device of this embodiment, since it is provided with a functional unit, the functional water having a predetermined function can be supplied to the mist generating unit and atomized. Thus, the effect brought by the function of the functional water based on the mist spray can be given to the user of the water treatment device and the surroundings of the water treatment device.

[0071] Hereinafter, the water treatment device according to the present embodiment will be described in detail with reference to the drawings.

[0072] [First embodiment]

[0073] The water treatment device A1 of the first embodiment is a water treatment device that, in addition to having a mode for purifying raw water supplied from a faucet and draining it (pure water mode), also has a mode for imparting predetermined functions to purified water and draining it (functional water mode), and a mist mode for atomizing and spraying a portion of the discharged water based on the pure water mode or the functional water mode.

[0074] Figure 1 1 is an explanatory diagram showing the appearance of a water treatment device A1 according to the first embodiment. Figure 2 Schematic diagram showing a simplified internal structure of the water treatment device A1 according to the first embodiment. Figure 2 In the schematic diagram of , the electrical signal is represented by a dotted line.

[0075] like Figure 1As shown, the water treatment device A1 includes a main body 10 having a mounting portion 11 mounted on a faucet of a faucet 101 , and a separate substantially box-shaped housing 20 connected to the main body 10 via a water supply hose 15 .

[0076] A switching valve 16 is provided on the main body 10, which switches the water passage through which raw water received from the faucet of the water pipe via the installation portion 11 passes into the main body 10, to a raw water flow path 14 for causing the raw water to flow toward a raw water outlet 12 sprayed out of the main body 10, and to a clean water flow path 31 for causing the raw water to flow toward the clean water portion 30 in the box 20 via the water supply hose 15.

[0077] The switching valve 16 is a branch plug including a plurality of valve cores, which can selectively switch the raw water received from the water pipe into at least two paths, and has a lever 13 that rotates within a predetermined angle range. The lever 13 that receives the operation of the user can perform a two-stage switching operation of raw water spraying from a raw water outlet 12 provided at the lower part of the main body 10 and target water spraying that can take out the water desired by the user (hereinafter also referred to as target water) from the water intake port 26a via the water intake pipe 26 provided on the side of the box 20.

[0078] The housing 20 stores a water purification unit 30, a hydrogen water generating unit 40 as a functional unit, a mist generating unit 60, and a control unit 50. The housing 20 also includes a power plug 29 (see Figure 2 ) is configured to receive power from a commercial power socket, etc., and under the control of the control unit 50, the hydrogen water generating unit 40 and the mist generating unit 60 operate.

[0079] In addition, if Figure 1 As shown, a display unit 21 is disposed on the front side of the housing 20, and various information presented to the user is displayed on the display unit 21. The display unit 21 includes a touch panel and also functions as an input unit.

[0080] Next, the internal structure of the box body 20 is described. Figure 2 As shown, a water purification unit 30, a hydrogen water generating unit 40, and a mist generating unit 60 are provided inside the housing 20 as a structure of a water flow system that processes the supplied water while passing through. These structures are connected by a flow path including a water purification flow path 31 and a mist generating flow path 41 formed in the housing 20. In addition, a control unit 50 is provided as a structure of an electrical system that performs electrical control and management required during water flow and treatment in the structure of the water flow system. These structures of the water flow system and the electrical system are accommodated and arranged in the housing 20, which is roughly box-shaped.

[0081] The purified water flow path 31 is configured to include: a water supply hose 15 connecting the main body 10 and the housing 20; and a flow path connecting the hydrogen water generating unit 40 and the water purification unit 30 in the housing 20. Water (raw water) as a raw material for generating purified water is received into the housing 20 via the water supply hose 15, and reaches the water intake pipe 26 extending from the upper surface of the housing 20 via each structure of the water flow system and each flow path connecting the structures. In this embodiment, one side of the water supply hose 15 is connected to the water outlet on the side of the main body 10 installed on the faucet 101, and the other side of the water supply hose 15 is connected to the water supply port on the side of the housing 20, so that tap water is supplied from the tap water pipe to the housing 20 as raw water. The raw water supplied into the housing 20 is supplied to the hydrogen water generating unit 40.

[0082] A flow sensor 32 is provided in the purified water flow path 31 from the switching valve 16 to the hydrogen water generating unit 40. The flow sensor 32 is, for example, an impeller flow meter, and is electrically connected to the control unit 50. The flow sensor 32 outputs an electrical signal (flow signal) corresponding to the amount of water flowing in the purified water flow path 31 to the control unit 50. The control unit 50 displays the accumulated flow calculated based on the input flow signal on the display unit 21.

[0083] The hydrogen water generating unit 40 is a functional unit that generates hydrogen water as functional water, and is composed of a hollow, roughly box-shaped electrolytic cell formed in a watertight state. At least two electrodes 44 are arranged inside the electrolytic cell, and the electrodes 44 are electrically connected to the control unit 50 in a manner that one side is an anode and the other side is a cathode. Inside the electrolytic cell, there is no diaphragm or the like that divides the anode side and the cathode side, and the water flowing close to each electrode 44 is mixed with each other. The raw water received from the faucet 101 and supplied to the hydrogen water generating unit 40 reaches the water purification unit 30 through the electrolytic cell.

[0084] The water purification unit 30 is configured to include a filter cartridge sealed with a hollow fiber membrane, activated carbon and other filter materials. The water purification unit 30 generates purified functional water by filtering and purifying the functional water by adsorbing odor substances and the like on the filter material. The functional water supplied to the water purification unit 30 through the hydrogen water generating unit 40 passes through the filter cartridge and reaches the water intake pipe 26 via the water intake path 25, and reaches the mist generating unit 60 via the mist generating flow path 41. In addition, the filter cartridge is replaced at a predetermined period or when the flow rate of water passing through the filter material exceeds a predetermined amount.

[0085] A branching portion 23 is provided in the middle of the mist generating flow path 41 connected to the mist generating unit 60 on the downstream side of the water purifying unit 30 so as to branch the flow path to the water intake path 25 on the water intake pipe 26 side. Downstream of the branching portion 23, the flow path diameter of the mist generating flow path 41 on the mist generating unit 60 side is narrower than that of the water intake path 25 on the water intake pipe 26 side (see Figure 3). Thus, the target amount of water taken out from the water intake port 26a can be ensured, and the amount of water required for atomization can be supplied to the mist generating unit 60.

[0086] Furthermore, a check valve 42 as a backflow prevention portion is provided in the mist generation flow path 41 downstream of the branch portion 23 and upstream of the connection position of the mist generation portion. The check valve 42 can prevent the functional water not used in the mist generation portion 60 from backflowing to the water intake path 25 and mixing.

[0087] The mist generating unit 60 has an atomizing mechanism, which atomizes the purified hydrogen water (purified functional water) after passing through the hydrogen water generating unit 40 and the water purifying unit 30 and sprays it outside the housing 20. In this embodiment, as the atomizing mechanism, a porous impregnated body 64 having water absorption and retention and an ultrasonic vibrator 65 are used, and the ultrasonic vibrator 65 vibrates the impregnated body 64 to make the water mist-like by an ultrasonic method (see Figure 3 ).

[0088] In addition, if Figure 3 As shown, the mist generating unit 60 is constituted by, for example, a hollow container 61. A nozzle 62 connected to the mist outlet 27 is provided at the upper portion of the container 61, and a water inlet 63 from the mist generating flow path 41 is provided at the bottom. In the container 61, the lower end of the impregnated body 64 is immersed in the water supplied from the mist generating flow path 41, so that the impregnated body 64 retains the water for atomization.

[0089] The purification function water atomized in the mist generating unit 60 is sprayed into the air from the mist outlet 27 formed on the upper surface side of the housing 20. Thus, the dry air is moistened.

[0090] The downstream side of the mist generation flow path 41 than the connection position of the mist generation unit 60 is a drainage path toward the drain port 43 for draining the remaining water that has not flowed into the mist generation unit 60. The drain port 43 is provided, for example, at the back or side of the housing 20, and a drain pipe for guiding the remaining water to the washing basin may be connected to the drain port 43 as required. In addition, in the present embodiment, when the flow rate in the mist generation flow path 41 downstream of the branch portion 23 is sufficiently less than the flow rate of the water intake path 25, the drainage path may be omitted.

[0091] Next, refer to Figure 4 The electrical structure of the water treatment device A1 will be described. Figure 4 is a block diagram showing the electrical structure of the water treatment device A1. Figure 4 In FIG. 1 , the electrical structure of the water treatment device A1 is indicated by solid lines, and the electrical structure added to the structure indicated by solid lines in water treatment devices of other embodiments and modified examples described later is indicated by dotted lines.

[0092] The control unit 50 is composed of a printed circuit board on which electronic components such as a computing device 51, a memory 52, and a switching element are mounted, and can realize the operation control of the water treatment device A1.

[0093] The control unit 50 is connected to a power button B1 to receive input from the user. In addition, the control unit 50 is connected to a display unit 21 having a touch panel. The display unit 21 displays a function water button F1 for switching the on / off action of the hydrogen water generating unit 40 and a mist button F2 for switching the on / off action of the mist generating unit 60, and receives input from the user. In addition, the control unit 50 can receive power from a commercial power source or the like via a power plug 29.

[0094] The flow sensor 32 is connected to the control unit 50. The memory 52 of the control unit 50 stores a program for calculating the integrated flow rate based on the electrical signal input from the flow sensor 32. The control unit 50 calculates the integrated flow rate according to the operation of the calculation device 51 and displays the calculation result on the display unit 21.

[0095] The control unit 50 is connected to the electrodes 44 of the hydrogen water generating unit 40. The control unit 50 refers to the applied voltage stored in the memory 52 according to the command of the operation device 51, and controls the power supply so as to apply a predetermined voltage to each electrode 44 disposed in the hydrogen water generating unit 40.

[0096] The control unit 50 is connected to the ultrasonic vibrator 65 of the mist generating unit 60. The control unit 50 vibrates the ultrasonic vibrator 65 at a vibration frequency corresponding to the spray intensity of the mist selected by the user (eg, light, medium, heavy, etc.).

[0097] Next, a series of operations in the water treatment device A1 having the above-described configuration will be described.

[0098] When the user presses power button B1 in water treatment device A1 with power plug 29 connected to a commercial power source, water treatment device A1 starts in the water purification mode and enters a waiting state for water supply or button input.

[0099] When the user turns on the faucet 101 to flow water into the purified water flow path 31 , the raw water passes through the water purification unit 30 without being electrolyzed in the electrolytic cell of the hydrogen water production unit 40 , and is ejected from the water intake pipe 26 as purified water.

[0100] In addition, if the user selects the functional water mode via the touch panel of the display unit 21, power is supplied to generate a predetermined DC voltage between the electrodes that become the anode or cathode of the electrolytic cell in the hydrogen water generating unit 40. Thus, purified hydrogen water (purified functional water) is sprayed from the water intake pipe 26 through the hydrogen water generating unit 40 and the water purification unit.

[0101] Similarly, if the user selects the mist mode via the touch panel of the display unit 21, power is supplied according to the control of the control unit 50, and the ultrasonic vibrator 65 is vibrated at a predetermined vibration frequency. When only the mist mode is selected, the mist generating unit 60 sprays purified water from the mist outlet 27 toward the outside. In addition, when both the functional water mode and the mist mode are selected, the mist generating unit 60 sprays purified functional water from the mist outlet 27 toward the outside.

[0102] The amount of water sprayed from the water intake pipe 26 , that is, the usage amount of purified water and purified functional water, and the operation time of the mist generating unit 60 are accumulated at any time and displayed on the display unit 21 .

[0103] The water treatment device having the above-mentioned structure can be said to have the following structure. That is, the water treatment device A1 of the present embodiment includes: a water purification unit 30 that filters raw water supplied from a faucet 101; a main body 10 that has a mounting portion 11 mounted on the faucet 101 and a switching valve 16 that switches between a purified water flow path 31 in which raw water passes through the water purification unit 30 and a raw water flow path 14 that does not pass through the water purification unit 30; a mist generating unit 60 that atomizes purified water filtered by the water purification unit 30; and a control unit 50 that controls the operation of the mist generating unit 60.

[0104] According to such a configuration, since at least purified water is atomized and sprayed in the peripheral space of the water treatment device A1, it is possible to maintain humidity during dryness and provide a moisturizing effect on the skin of the user's face and the like.

[0105] In addition, the water treatment device A1 of the present embodiment is provided with a functional unit (hydrogen water generating unit 40) for generating functional water, and the mist generating unit 60 sprays atomized functional water from the mist outlet 27, and the mist outlet 27 is provided at a position different from the clean water outlet of the clean water filtered by the water purifying unit 30. More specifically, the clean water outlet is a water intake port 26a facing downward in the water intake pipe 26 protruding from the left side relative to the upper center of the housing 20, and the mist outlet 27 is a hole portion of the housing 20 that is provided on the right side relative to the upper center and opens upward.

[0106] The functional unit is a hydrogen water generating unit 40 including an electrode for generating hydrogen, and the hydrogen water generating unit 40 is provided upstream of the water purifying unit 30 .

[0107] According to such a structure, since the mist generating unit 60 atomizes the hydrogen water as the functional water, it is expected that the user's face and other skin will be moisturized and the roughness of the skin will be prevented. In addition, the functional water sprayed from the hydrogen water generating unit 40 passes through the water purifying unit 30, so that the odor caused by the substance generated by electrolysis in the functional unit can be removed in the water purifying unit 30.

[0108] The water treatment device A1 of this embodiment includes a branch portion 23 downstream of the water purification unit 30 , which branches the purified water flow path 31 into a water intake path 25 leading to the purified water outlet (water intake port 26 a ) and a mist generation flow path 41 connected to the mist generation unit 60 .

[0109] According to such a configuration, the user can easily guide the amount of water required for generating mist to the mist generating unit 60 simply by turning on the faucet 101 to flow water into the clean water flow path 31 .

[0110] The mist generation flow path 41 is configured to have a smaller flow rate than the water intake path 25. Specifically, by making the flow path diameter of the mist generation flow path 41 smaller than the water intake path 25, the flow rate of water in the mist generation flow path 41 is reduced.

[0111] According to such a configuration, a sufficient amount of target water to be used as drinking water or the like can be ensured, and the amount of excess water not used in the mist generating unit 60 can be reduced, thereby suppressing wasteful use of water.

[0112] In addition, a backflow prevention portion is provided upstream of the mist generating portion 60 in the mist generating flow path 41. In the present embodiment, the backflow prevention portion is a check valve 42.

[0113] According to such a structure, in the mist generating flow path 41, even if the water guided downstream from the branch portion 23 is not used in the mist generating portion 60 but is retained in the mist generating flow path 41, the retained water can be prevented from backflowing by the backflow prevention portion and flowing in the water intake pipe 26 via the water intake path 25, and the purified water as drinking water can be maintained hygienically. In addition, the backflow prevention portion is a check valve 42, thereby reliably preventing backflow.

[0114] Furthermore, the mist generating flow path 41 has a drain port 43 for draining excess water that has not flowed into the mist generating unit 60 .

[0115] According to such a configuration, excess water that has not flowed into the mist generating unit 60 can be discharged to the outside from the flow path.

[0116] In the water treatment device A1 of the present embodiment, the water intake port 26a of the water intake pipe 26 is located sufficiently away from the water outlet 43. This prevents the wastewater discharged from the water outlet 43 from mixing with the target water ejected from the water intake port 26a.

[0117] In addition, a mist outlet 27 for spraying the mist generated in the mist generating unit 60 toward the outside is provided on the upper surface of the housing 20 that houses the water purification unit 30 .

[0118] According to such a configuration, mist can be sprayed over a wide range around the wash basin where the water treatment device A1 is installed.

[0119] [Second embodiment]

[0120] Next, a second embodiment of the water treatment device of the present disclosure will be described.

[0121] In the embodiments described below, the same names or the same reference numerals are used for configurations that are common to or correspond to those in the first embodiment, and description of duplicate contents will be appropriately omitted.

[0122] Figure 5 1 is an explanatory diagram showing the appearance of a water treatment device A2 according to the second embodiment. Figure 6 This is a schematic diagram showing a simplified internal structure of the water treatment device A2 of the second embodiment. Figure 4 The electrical structure of the water treatment device A2 according to the second embodiment will be described with reference to the block diagram of FIG.

[0123] In the first embodiment, the mist generating unit 60 and the display unit 21 are arranged in the housing 20 which is separate from the main body 10 . However, the water treatment device A2 of this embodiment is different in that the mist generating unit 60 and the flow rate display unit 121 are arranged in the main body 110 .

[0124] Between the main body 110 and the box 120, in addition to the water supply hose 15, there are also provided a water purification hose 17 for returning the target water from the box 120 to the main body 110, and a cable 19 for supplying power from the power plug 29 to the mist generating unit 60 of the main body 110 and the flow display unit 121.

[0125] The water purification hose 17 is provided in place of the water intake pipe 26 of the water treatment device of the first embodiment. The raw water supplied from the faucet 101 is received into the housing 120 via the water supply hose 15 by the switching of the switching valve 16, and reaches the water purification hose 17 through the hydrogen water generating unit 40 and the water purification unit 30 as functional units in the housing 120. In this embodiment, one end of the water purification hose 17 is connected to the water inlet of the main body 110 installed on the faucet 101, and the other end of the water purification hose 17 is connected to the spray outlet on the housing 120 side, so that the target water flows back from the housing 120 to the main body 110.

[0126] The target water outlet 112 is provided at a position different from the raw water outlet 12 in the lower part of the main body 110. The main body 110 has a branching portion 23 that branches the purified water flow path 31 into a water intake path 25 that reaches the target water outlet 112 and a mist generation flow path 41 connected to the mist generation unit 60.

[0127] In addition, a reservoir 70 is provided at a connection portion of the mist generating flow path 41 connected to the mist generating unit 60. The reservoir 70 stores a predetermined amount of functional water atomized in the mist generating unit 60. The reservoir 70 only needs to be formed so as to be able to communicate with the mist generating unit 60 and the mist generating flow path 41, and for example, may be a structure that can partially expand the flow path diameter of the mist generating flow path 41 and store water.

[0128] In addition, a heater 71 is provided in the storage section 70. The heater 71 is electrically connected to the control section 50. The control section 50 drives the heater 71 at a low output when the mist generating section 60 is driven, and drives the heater 71 at a high output when the mist generating section 60 is not driven. More specifically, when the mist generating section 60 is driven, the control section 50 drives the heater 71 at a predetermined output to keep the water warm, for example, so that the water temperature of the water stored in the storage section 70 becomes about 40°C. When the mist generating section 60 is not driven, the control section 50 drives the heater 71 at a larger output than when the mist generating section 60 is driven to heat the water, for example, so that the water temperature of the water stored in the storage section 70 becomes 75°C or more.

[0129] Here, the mist generating unit 60 is not driven when the faucet 101 is not turned on, when the switching valve 16 is in a position that allows raw water to flow to the raw water flow path 14 even when the faucet 101 is turned on, or when the switching valve 16 is in a position that allows raw water to flow to the purified water flow path 31 even when the faucet 101 is turned on, and when the mist mode is not selected, etc., the mist generating unit 60 stops driving. That is, the control unit 50 performs control to make the heater output when the mist generating unit 60 is not driven larger than the heater output when the mist generating unit 60 is driven, so that the inside of the storage unit 70 can be sterilized by heat when the mist generating function is not used.

[0130] Furthermore, when the mist generating unit 60 is not driven, it is not necessary to always drive the heater 71 continuously at a high output, and it is sufficient as long as the water temperature of the accumulated water in the accumulation unit 70 can be maintained at a state of 75° C. or above for a certain period of time during which sterilization is effective. Therefore, the control unit 50 may be configured to, for example, execute control to stop the power supply to the heater 71 after the heater 71 is driven at a high output for a predetermined driving time (e.g., 10 minutes).

[0131] In addition, when the mist generating function is not used, the heating of the storage section 70 by the heater 71 can be performed at a frequency that can maintain the sanitary state in the storage section 70. Therefore, when the mist generating section 60 is not driven, the control section 50 can also, for example, determine whether a preset stop time (e.g., one hour) has passed since the last high-output drive, and when the set stop time has passed, control the operation of the heater 71 to drive the heater for a predetermined drive time (e.g., 10 minutes) at high output, and drive the heater intermittently. That is, by suppressing the high-output drive time of the heater 71, the increase in power consumption when the mist generating function is not used can be suppressed.

[0132] On the other hand, when the mist generating unit 60 is driven, the heater 71 is driven with a smaller output than when the mist generating unit 60 is not driven, so that mist of a comfortable temperature (for example, 30° C. to 40° C.) can be supplied to the user.

[0133] The upper surface of the main body 110 is provided with a mist outlet 27 that opens upward and a mist button F2 that switches the mist mode on / off. The mist button F2 is electrically connected to the control unit 50. According to the drive command from the control unit 50, the mist generated by the mist generating unit 60 in the box 120 is sprayed to the outside from the mist outlet 27. In this way, by setting the mist button F2 on the upper surface of the main body 110, the user can easily and quickly drive and stop the mist generating unit 60. In addition, the mist button F2 and the mist outlet 27 are set on the same surface, and the user can observe and recognize them in the same field of view, so the user can easily confirm the spraying and stopping of the mist from the mist outlet 27 in conjunction with the operation of the mist button F2. In addition, similar to the water treatment device A1 of the first embodiment, the functional water button F1 that switches the functional water mode on / off is provided as a selection button displayed on the display unit 21 having a touch panel.

[0134] A flow rate display unit 121 is disposed on the front surface of the main body 110 separately from the display unit 21 of the housing 120. The flow rate display unit 121 displays the integrated amount of raw water based on the electrical signal of the flow rate sensor 32.

[0135] The downstream side of the mist generating section 60 of the mist generating flow path 41 serves as a drainage path toward a drainage port 43 for discharging excess water that has not flowed into the mist generating section 60 .

[0136] Figure 7 1 is a schematic diagram showing the lower surface side of the main body 110. Figure 7As shown, the drain port 43 is located at a position different from the original water outlet 12 and the target water outlet 112 on the lower surface side of the main body 110, and is set at a position on the rear side of the mounting portion 11. In addition, the drain port 43 is preferably away from the target water outlet 112. In this way, the drain port 43 is set at a position behind the mounting portion 11, so that the drainage discharged from the drain port 43 can be prevented from mixing with the target water sprayed from the target water outlet 112. In addition, the target water outlet 112 is set at a position forward of the mounting portion 11, so that the separation distance from the drain port 43 can be increased, and the drainage discharged from the drain port 43 can be further prevented from mixing with the target water sprayed from the target water outlet 112.

[0137] The water purification unit 30, the hydrogen water generating unit 40 as a functional unit, and the control unit 50 are arranged in the housing 120. The housing 120 may be arranged in a range where the water hose 15, the water purification hose 17, and the cable 19 can be routed, for example, in a space under a sink.

[0138] When the switching valve 16 is switched to direct raw water toward the purified water flow path 31 of the water purification unit 30 by the user's operation of the lever 13 , raw water supplied from the faucet 101 is supplied into the tank 120 via the water supply hose 15 , and target water flowing back from the tank 120 is sprayed from the target water spray port 112 .

[0139] At this time, when the mist button F2 is pressed by the user, the mist generating unit 60 is operated and mist is sprayed into the air from the mist outlet 27 .

[0140] The water treatment device having the above structure can be said to have the following structure. That is, the water treatment device A2 of this embodiment has the mist outlet 27 provided on the upper surface of the main body 110. The mist outlet 27 is provided in the main body 110 at a position forward of the mounting portion 11.

[0141] According to such a structure, the mist can be sprayed at a position closer to the user.

[0142] Moreover, in the water treatment device A2 of the present embodiment, the reservoir 70 is provided at the connection portion of the mist generation flow path 41 connected to the mist generation unit 60 .

[0143] According to such a configuration, a predetermined amount of functional water can be stored in the storage portion 70 , and thus idling of the mist generating portion 60 can be prevented.

[0144] Furthermore, the storage portion 70 is provided with a heater 71 as a heating mechanism.

[0145] According to such a configuration, the heated hot mist can be provided to the user from the mist outlet 27 .

[0146] The control unit 50 is a member that drives the heater 71 with different outputs when the mist generating unit 60 is driven and when it is not driven.

[0147] According to such a configuration, when the mist generating unit 60 is not driven, the heater 71 is driven at a high output, and sterilization can be performed using the heat in the storage unit 70 .

[0148] In addition, the storage unit 70 may also be provided as a part of the mist generating unit 60. For example, Figure 3 The bottom of the container 61 described above accumulates a certain amount of water and is replaced by a reservoir.

[0149] [Modification of the Second Embodiment]

[0150] Next, a modification of the second embodiment of the water treatment device of the present disclosure will be described. This modification relates to the temperature adjustment of the storage unit 70 .

[0151] The water treatment device A2 may also include a Peltier element as a cooling mechanism in the storage section 70 instead of the heater 71. The Peltier element is electrically connected to the control section 50, and the control section 50 drives the Peltier element with a high output when the mist generating section 60 is driven, and drives the Peltier element with a low output when the mist generating section 60 is not driven. More specifically, when the mist generating section 60 is driven, the control section 50 drives the Peltier element with a predetermined output, and cools the water in the storage section 70 in such a manner that the water temperature becomes a desired temperature (e.g., 10° C.). When the mist generating section 60 is not driven, the control section 50 drives the Peltier element with an output smaller than when the mist generating section 60 is driven, and maintains the water temperature of the water in the storage section 70 at a constant temperature. The constant temperature at this time is preferably lower than the optimal proliferation temperature of bacteria classified as mesophilic bacteria, for example, from the viewpoint of inhibiting the reproduction of bacteria.

[0152] When the mist generating unit 60 is driven, if the Peltier element is driven with a higher output than when not driven, the stored water in the storage unit 70 is strongly cooled, and cooling mist is sprayed from the mist outlet 27. Thus, the user can feel cool through the cooling mist during the high temperature period in summer.

[0153] Furthermore, by providing a circuit for changing the direction of current with respect to the Peltier element in the control unit 50, a mist temperature adjustment mechanism for selectively performing heating and cooling may be provided in the storage unit 70. In this case, a selection button for selecting heating and cooling is displayed on the display unit 21, so that the user can select the mist temperature.

[0154] When the Peltier element is used as the heating mechanism, similarly to the case of the heater 71, when the mist generating unit 60 is driven, the control unit 50 drives the Peltier element with a predetermined output, for example, to keep the temperature of the water stored in the storage unit 70 at about 40° C. When the mist generating unit 60 is not driven, the control unit 50 drives the Peltier element with a larger output than when the mist generating unit 60 is driven, for example, to heat the water so that the temperature of the water stored in the storage unit 70 becomes 75° C. or higher.

[0155] The water treatment device having the above-described structure can be said to have the following structure. That is, a cooling mechanism is provided in the storage portion 70 of the water treatment device A2 of the present modification.

[0156] According to such a configuration, it is possible to provide the user with mist at a desired temperature according to the type of functional water.

[0157] In the first embodiment, the second embodiment and the modified examples thereof, the water purification unit 30 and the functional unit (hydrogen water generating unit 40) are arranged in the housing 20, 120 and are separated from the main body 10, 110. However, the structure separated from the main body 10, 110 can be changed. For example, only the functional unit can be set as a separate body, and all other structures can be set in the main body installed on the faucet 101.

[0158] In addition, the mounting portion 11 includes not only a member mounted on the faucet of the faucet, but also a member mounted on the raw water outlet that becomes the water stop faucet of each water-using equipment such as the kitchen and the bathroom. For example, the main body including the water purification unit and the switching valve may be clamped on the piping under the sink, and the functional unit and the mist generating unit 60 may be provided as a separate body on the faucet side. In this case, the raw water outlet 12 provided in the main body and the water intake 26a for purified water are naturally deformed into a shape that can be connected to the piping.

[0159] [Third Embodiment]

[0160] Next, a third embodiment of the water treatment device of the present disclosure will be described.

[0161] In the embodiments described below, the same names or the same reference numerals are used for configurations that are common to or correspond to those in the first embodiment and the second embodiment, and description of duplicate contents will be appropriately omitted.

[0162] Figure 8 as well as Fig. 9 1 is an explanatory diagram showing the appearance of a water treatment device A3 according to a third embodiment. Figure 8 Indicates the state where the power supply unit 80 is installed. Fig. 9 This shows a state where the power supply unit 80 is removed. Fig.10This is a schematic diagram showing a simplified internal structure of a water treatment device A3 according to the third embodiment. Fig.11 It is a schematic bottom view of the water treatment device A3. Fig.12 It is a block diagram showing the electrical configuration of a water treatment device A3 according to the third embodiment.

[0163] The water treatment device A3 of this embodiment is configured such that a water purification unit 30, an ion water generating unit 140 as a functional unit, a control unit 50, and a power supply unit 80 are integrally connected to a main body 210 having a mounting portion 11. That is, the main body 210 is composed of a main body central portion 220 having a mounting portion 11, a cartridge housing 230 extending from the left side of the main body central portion 220 and housing the water purification unit 30, and a power supply unit 80 detachably connected to the right side of the main body central portion 220.

[0164] In the main body central part 220, which is the central part of the water treatment device A3, a switching valve 16 and a control unit 50 are arranged in addition to the mounting unit 11, and a plurality of water passages constituting a water passing system are formed. Each water passage is configured to communicate with the raw water outlet 12 provided on the lower surface side of the main body central part 220 and the water purification unit 30 connected to the left side of the main body central part 220.

[0165] A lever 13 for a user to operate the switching valve 16 to switch the flow path is arranged on the front side of the main body central portion 220 .

[0166] A flow rate display unit 121 is disposed on the upper surface of the main body central portion 220. Similar to the second embodiment, the flow rate display unit 121 displays the integrated amount of water flowing toward the water purification unit 30 based on the electrical signal of the flow rate sensor 32.

[0167] In addition, a functional water button F1 is disposed on the upper surface of the main body central portion 220. The functional water button F1 is electrically connected to the control unit 50. In this embodiment, the user presses the functional water button F1 to select the functional water mode, thereby performing on / off control of driving the ion water generating unit 140 and the mist generating unit 60.

[0168] The cartridge housing 230 is a part of the main body 210 that is formed integrally with the main body 210 to form a cylindrical shape with a circular cross section, and can be loaded and unloaded to store the cylindrical water purification filter cartridge constituting the water purification unit 30. In addition, the cross-sectional shape of the cartridge housing 230 is not limited to a circle, and can also be an ellipse, or a polygon such as a quadrilateral. In addition, the ion water generating unit 140 and the mist generating unit 60 are stored in the cartridge housing 230. The rear side of the cartridge housing 230 becomes a cover 231, and the water purification filter cartridge can be replaced by opening the cover 231.

[0169] A target water discharge port 112 is provided on the lower surface side of the cartridge case 230 , and the target water discharge port 112 discharges the target water after passing through the water purification unit 30 and the ion water generating unit 140 .

[0170] The power supply unit 80 has a substantially rectangular parallelepiped outer shape, and houses a storage battery such as a lithium-ion battery as a power source. A mating protrusion 81 having a substantially T-shaped cross-sectional shape is installed on the surface of the power supply unit 80 facing the main body central portion 220, that is, on the left side. The mating protrusion 81 can be mated with a rail-shaped mating recess 221 provided on the right side of the main body central portion 220 by sliding. A contact for power supply is provided on the flat surface of the T-shaped head of the mating protrusion 81. The mating protrusion 81 is slidably mated with the mating recess 221, so that the contact for power supply on the mating protrusion 81 side contacts with the contact for power receiving provided on the right side of the main body 210, which is the bottom of the mating recess 221. Thus, power is supplied from the power supply unit 80 to the structure of the electrical system of the main body 210. The power source unit 80 is configured to be easily removed by sliding relative to the main body 210 to release the engagement of the engagement protrusion 81 with the engagement recess 221 , and to charge the internal storage battery using a charger.

[0171] In addition, all-solid batteries can also be used as storage batteries for power sources. Compared with lithium-ion batteries that use electrolytes, all-solid batteries use solid electrolytes. The operating temperature range of all-solid batteries is wider than that of lithium-ion batteries, and no liquid leakage occurs, so they can be used even in strict temperature environments. As such an all-solid battery, it is preferred to use a battery in which at least one of the positive electrode, negative electrode, and solid electrolyte layer contains a sulfide-based solid electrolyte.

[0172] In addition, a substantially U-shaped rib 223 is provided on the right side of the main body central portion 220 so as to surround the right side in three directions. That is, the rib 223 is provided to surround the edge of the right side of the main body central portion 220 except for the direction (rear side) of the receiving opening of the fitting concave portion 221 that becomes the fitting convex portion 81. The rib 223 is composed of a longitudinal rib 223a protruding in the direction along the plane of the right side of the main body central portion 220, and a transverse rib 223b protruding in the direction orthogonal to the plane of the right side.

[0173] The ribs 223 are used to prevent water from entering the contact point between the main body central portion 220 and the power supply unit 80. For example, when a user uses the raw water sprayed from the raw water spray port 12 to wash dishes, the longitudinal ribs 223a act as a dam to prevent splashed water droplets from flowing from the upper surface of the main body 210 to the power supply unit 80. In addition, the transverse ribs 223b effectively prevent water flowing over the longitudinal ribs 223a from entering between the power supply unit 80 and the main body central portion 220.

[0174] In addition, in the present embodiment, both the longitudinal rib 223a and the transverse rib 223b are arranged to surround the edge of the right side of the main body central part 220 except the direction of the receiving port of the fitting concave part 221 that becomes the fitting convex part 81, but the longitudinal rib 223a can also be formed into a flange shape that surrounds the edge of the right side of the main body central part 220 all around. That is, the rib 223 only needs to have a cutout portion of the insertion end side cutout of the power supply part 80 in the transverse rib 223b that protrudes in the direction that surrounds the engaging concave part 221 and is orthogonal to the right side of the main body central part 220. In addition, the longitudinal rib 223a can be omitted and only the transverse rib 223b can be provided, and conversely, the transverse rib 223b can be omitted and only the longitudinal rib 223a can be provided.

[0175] The internal structure of the main body 210 will be described. The ion water generating unit 140 and the mist generating unit 60 as functional units are housed in the cartridge case 230 together with the water purifying unit 30 .

[0176] The switching valve 116 is provided with an angle sensor 33. The angle sensor 33 detects the rotation angle corresponding to the operation amount of the rod 13, and is electrically connected to the control unit 50. The control unit 50 obtains the selected flow path information based on the rotation position of the rod based on the electrical signal of the angle sensor 33. In addition, the acquisition of the flow path information may also be replaced by other mechanisms such as a circuit in which the contacts are closed and energized when the rod 13 moves to each rotation position, instead of the angle sensor 33 contacts.

[0177] The ionized water generating unit 140 is arranged at a position downstream of the water purifying unit 30 in the purified water flow path 31. An electric switching valve 36 operated by the drive of the motor 37 is interposed between the water purifying unit 30 and the ionized water generating unit 140. The switching valve 36 is electrically connected to the control unit 50, and the control unit 50 drives the motor 37 to operate the switching valve 36 based on the flow path information selected by the rod 13. That is, the switching valve 36 switches between a flow path that directs the purified water that has passed through the water purifying unit 30 only toward the target water outlet 112 and a flow path that supplies the purified water that has passed through the water purifying unit 30 to the ionized water generating unit 140.

[0178] The ion water generating unit 140 is a functional unit for generating ion water as functional water, and is composed of a hollow, roughly box-shaped electrolytic cell formed in a watertight state. The electrolytic cell is a two-chamber type electrolytic cell whose interior is divided into a cathode chamber 141 and an anode chamber 142 by a diaphragm, and an electrode 45 serving as a cathode and an electrode 45 serving as an anode are respectively arranged in each chamber. Each electrode 45 is electrically connected to a control unit 50. The interior of the electrolytic cell is divided into a cathode chamber 141 and an anode chamber 142, and the acidic ion water and alkaline ion water in each chamber do not mix with each other, and flow from the ion water outlets provided in the cathode chamber 141 and the anode chamber 142 to the downstream flow path.

[0179] The ionized water outlet on the cathode chamber 141 side of the electrolytic cell is connected to the water intake passage 125 toward the target water ejection outlet 112 , and alkaline ionized water is ejected from the target water ejection outlet 112 on the lower surface of the cartridge case 230 .

[0180] The ion water outlet on the anode chamber 142 side of the electrolytic cell reaches the mist generating unit 60 connected to the mist generating flow path 41. In the mist generating unit 60, the acidic ion water called astringent water is atomized. The acidic ion water atomized in the mist generating unit 60 is sprayed from the mist outlet 27 provided in an upwardly open manner on the upper surface side of the cartridge housing 230. In addition, the mist outlet 27 may also be provided in front of the cartridge housing 230.

[0181] The acidic ion water not used in the mist generating unit 60 is discharged from the drain port 43. Fig.11 As shown, the drain port 43 is arranged at a position different from the target water outlet 112 from which purified water and alkaline ionized water are ejected on the lower surface side of the cartridge housing 230. Specifically, the target water outlet 112 is arranged on the lower surface of the cartridge housing 230 on the front side of the mounting portion 11, whereas the drain port 43 is arranged on the lower surface of the main body central portion 220 on the rear side of the mounting portion 11. Thus, it is achieved to prevent the acidic ionized water from mixing with the alkaline ionized water used as a beverage.

[0182] That is, the target water outlet 112 is arranged on the left side which is closer to the front of the mounting part 11 and becomes one side in the left-right direction, and the drain port 43 is arranged on the right side which is closer to the rear of the mounting part 11 and becomes the other side in the left-right direction. In this way, since the drain port 43 is arranged at a position different from the target water outlet 112 and is arranged at a position separated in the left-right direction to the rear of the mounting part 11, it is possible to prevent the acidic ion water from mixing into the alkaline ion water sprayed from the target water outlet 112. In addition, the target water outlet 112 is arranged at a position closer to the front of the mounting part 11, so that the drain port 43 and the target water outlet 112 are also separated in the front-back direction. Thus, the separation distance between the drain port 43 and the target water outlet 112 can be further increased. In this way, the drain port 43 and the target water outlet 112 are separated in the front-back direction and the left-right direction and are arranged on a substantially diagonal line across the raw water outlet 12, so that the acidic ion water sprayed from the drain port 43 can be further prevented from mixing into the alkaline ion water sprayed from the target water outlet 112.

[0183] In this embodiment, the electrolytic cell divided into the cathode chamber 141 and the anode chamber 142 branches the flow path into the purified water flow path 31 and the mist generation flow path 41. Therefore, the electrolytic cell also functions as the branching portion 23 in the water treatment device A1 of the first embodiment.

[0184] Next, a series of operations in the water treatment device A3 having the above-mentioned configuration will be described.

[0185] When the user presses the functional water button F1 and selects the functional water mode, if the faucet 101 is turned on to flow water through the purified water flow path 31, the raw water passes through the purified water unit 30 and reaches the electrolytic cell of the ionized water generating unit 140. In the electrolytic cell, electrolysis is performed by the electrodes of each chamber supplied with electric power, and the alkaline ionized water passing through the cathode chamber 141 side of the electrolytic cell is ejected from the target water ejection port 112.

[0186] The acidic ion water that has passed through the anode chamber 142 of the electrolytic cell and reached the mist generating unit 60 is atomized by the vibration of the ultrasonic vibrator 65 supplied with power. Thus, the mist acidic ion water is sprayed out from the mist outlet 27 to the outside.

[0187] The water treatment device having the above structure can be said to have the following structure. That is, the functional part of the water treatment device A3 of this embodiment is an ion water generating unit 140 having an anode, a cathode, and a diaphragm that divides the interior into an anode side and a cathode side, and the flow path for making the electrolyzed water flow out from the anode side of the ion water generating unit 140 using the ion water generating unit 140 as a branch part is the mist generating flow path 41.

[0188] According to such a configuration, the mist generating unit 60 atomizes and sprays the electrolytic water, ie, acidic ionized water, which flows out from the anode side of the ionized water generating unit 140. Therefore, the effect of the acidic ionized water, ie, astringent effect such as firming of the skin of the user, can be expected.

[0189] In addition, the water discharge port 43 in the mist generating flow path 41 is provided on the lower surface of the main body 210 at the rear side relative to the mounting portion 11 .

[0190] According to such a configuration, the user can take out raw water and purified water separately without mixing the excess water that has not flowed into the mist generating unit 60 .

[0191] The purified water outlet (target water outlet 112 ) is provided on either side of the main body 210 relative to the mounting portion 11 , and the mist outlet 27 is provided on the side of the main body 210 where the purified water outlet (target water outlet 112 ) is provided.

[0192] In such a structure, the mist outlet 27 can also be provided at a position higher than the upper surface of the main body central portion 220 , so that the mist can easily reach the user.

[0193] In addition, the water treatment device A3 of the present embodiment is provided with a water purification unit 30, a functional unit, a control unit 50 and a power supply unit 80 integrally in the main body 210. Relative to the position of the installation part 11, the water purification unit 30 is arranged on one side (left side) and the power supply unit 80 is arranged on the other side (right side).

[0194] According to such a structure, in the water treatment device A3, the water purification unit 30 which becomes heavy due to the presence of water and the power supply unit 80 which becomes heavy due to the weight of the battery are arranged so as to easily achieve left-right weight balance relative to the installation position of the faucet 101, thereby stably installing the faucet 101. In addition, if the arrangement is capable of achieving weight balance, the power supply unit 80 and the water purification unit 30 may be arranged front and back with the installation unit 11 interposed therebetween.

[0195] [Modification of the Third Embodiment]

[0196] Next, a modification of the third embodiment of the water treatment device of the present disclosure will be described. Fig.13 It is an explanatory diagram showing the appearance of a water treatment device A3 according to a modified example of the third embodiment.

[0197] The water treatment device A3 of this modified example has a tapered surface 232 disposed above the front end of the cartridge case 230 and a mist outlet 27 disposed on the tapered surface 232 so that mist can be sprayed obliquely forward.

[0198] The water treatment device A3 having the above-described structure can be said to have the following structure: That is, the mist outlet 27 of the water treatment device A3 of the present embodiment and the modified example is provided in the main body 210 at a position forward of the mounting portion 11 .

[0199] According to such a configuration, since the mist can be supplied from a position closer to the user, the effect of the functional water can be further exerted on the user's face.

[0200] [Fourth Embodiment]

[0201] Next, a fourth embodiment of the water treatment device of the present disclosure will be described.

[0202] In the embodiments described below, the same names or the same reference numerals are used for configurations that are common to or correspond to those in the first embodiment, the second embodiment, and the third embodiment, and description of duplicate contents will be appropriately omitted.

[0203] Fig.14 1 is an explanatory diagram showing the appearance of a water treatment device A4 according to a fourth embodiment. Fig.15 This is a schematic diagram showing a simplified internal structure of a water treatment device A4 according to the fourth embodiment. Fig.16 1 is a schematic diagram showing the lower surface side of a water treatment device A4 according to a fourth embodiment. Fig.17 is a block diagram showing the electrical structure. Fig.17 In the water treatment device of the modified example described later, the electrical structure added to the structure shown by the solid line in the figure is indicated by the dotted line.

[0204] The water treatment device A4 of this embodiment is configured such that a water purification unit 30, an ozone water generating unit 240 as a functional unit, and a control unit 50 are integrally connected to a main body 310 having an installation portion 11. Specifically, a cartridge housing 230 including the water purification unit 30 is disposed on the left side with the installation portion 11 as the center, and a lever 13 operated by a user to switch the switching valve 116 is disposed on the right side. In the main body 310, the water purification unit 30, the ozone water generating unit 240, and the mist generating unit 60 are stored in the cartridge housing 230, and the control unit 50 is stored in the main body central portion 220. In addition, the main body 210 is provided with a power plug 29 (see Fig.15 ) is configured to receive power from a commercial power socket, etc., and under the control of the control unit 50, the ozone water generating unit 240 and the mist generating unit 60 operate.

[0205] The lower surface of the main body central portion 220 is provided with a functional water outlet 114 in addition to the raw water outlet 12. The lower surface of the cartridge case 230 is provided with a purified water outlet 113 for discharging purified water that has passed through the water purification unit 30 alone.

[0206] A flow rate display unit 121 is disposed on the upper surface side of the main body central portion 220. The flow rate display unit 121 displays the integrated water volume of the raw water based on the electrical signal of the flow rate sensor 32, similarly to the second embodiment and the third embodiment.

[0207] In addition, a power button B1 for switching on / off the power supply from the commercial power supply and a function water button F1 for switching on / off the driving of the ozone water generating unit 240 and the mist generating unit 60 are arranged on the upper surface of the main body central portion 220. The power button B1 and the function water button F1 are electrically connected to the control unit 50.

[0208] When the user presses the power button B1 in the water treatment device A4 connected to the commercial power supply or the like with the power plug 29, the water treatment device A4 starts in the water purification mode and becomes a waiting state for water supply or button input. In the present embodiment, the following control is performed: when the user presses the function water button F1 for the first time, the drive of the ozone water generating unit 240 is turned on, when the user presses the function water button F1 for the second time, the drive of the mist generating unit 60 is turned on, and when the user presses the function water button F1 for the third time, the ozone water generating unit 240 and the mist generating unit 60 are turned off.

[0209] The internal structure of the main body 310 will be described. In the purified water flow path 31 downstream of the switching valve 116, the water purification unit 30, the electric switching valve 36, and the ozone water generating unit 240 are arranged in this order.

[0210] The electric switching valve 36 switches the flow path by driving the motor 37 electrically connected to the control unit 50. When the function water button F1 is not operated and the ozone water generating unit 240 and the mist generating unit 60 are not driven, the switching valve 36 sets the flow path so that the purified water received from the purified water flow path 31 and passed through the water purifying unit 30 is directed to the purified water outlet 113. On the other hand, when the user presses the function water button F1, the control unit 50 operates the switching valve 36 and switches the flow path so that the purified water received from the purified water flow path 31 and passed through the water purifying unit 30 is directed to the ozone water generating unit 240.

[0211] The ozone water generating unit 240 is a functional unit for generating ozone water as functional water, and is composed of an electrolysis unit having an anode and a cathode. The electrolysis unit is configured to receive purified water as raw water, dissolve ozone generated by electrolyzing water in water, and obtain ozone water. Power is supplied to each electrode 46 that becomes an anode or a cathode according to a command of the control unit 50.

[0212] A branch portion 123 is provided in the middle of the mist generation flow path 41 connected to the mist generation unit 60, which is the downstream side of the ozone water generation unit 240. The branch portion 123 branches from the mist generation flow path 41 to the ozone water outlet, i.e., the functional water flow path 28, which is the functional water outlet 114, upstream of the mist generation unit 60.

[0213] A return path 68 is formed downstream of the mist generating section 60 of the mist generating flow path 41 to return excess ozone water not used in the mist generating section 60 to the functional water flow path 28 .

[0214] like Fig.16 As shown, the functional water outlet 114 is arranged at a different position from the clean water outlet 113 that sprays clean water on the lower surface side of the cylindrical barrel shell 230 with a circular cross-section. Specifically, the clean water outlet 113 is arranged on the lower surface of the barrel shell 230 in the left front of the mounting portion 11, and in contrast, the functional water outlet 114 is arranged on the lower surface of the main body central portion 220 in the right side of the mounting portion 11. Thus, the clean water and the ozone water can be taken out without mixing with each other. In addition, since the functional water outlet 114 and the clean water outlet 113 are both arranged in a position in front of the mounting portion 11, the convenience of use can be improved from the perspective of taking in functional water and clean water.

[0215] Next, a series of operations of the water treatment device A4 having the above-mentioned configuration will be described.

[0216] When the user presses the functional water button and selects the functional water mode and the mist mode, and opens the faucet 101 to flow water through the purified water flow path 31, the raw water passes through the water purification unit 30 and reaches the electrolysis unit of the ozone water generating unit 240. In the electrolysis unit, each electrode supplied with electric power performs electrolysis, and the generated ozone water is sprayed out from the functional water spray port 114.

[0217] The ozone water that has passed through the ozone water production unit 240 and reached the mist generation unit 60 is atomized by the driving of the ultrasonic vibrator 65 to which the power is supplied.

[0218] The ozone water atomized in the mist generating unit 60 is sprayed from the mist outlet 27 provided on the side of the main body central portion 220 where the rod 13 is arranged. The sprayed ozone water is applied to the rod 13 that the user touches with his hand, so that the rod 13 can be kept clean by the sterilization effect of the ozone water.

[0219] In addition, in the present embodiment, the reflux path 68 allows the remaining water that has not flowed into the mist generating section 60 to flow back to the functional water flow path 28, but it may also be that a flow path branching from the functional water flow path 28 is connected to the flow path toward the purified water outlet 113, so that part or all of the ozone water flowing in the functional water flow path 28 flows back, thereby sterilizing the purified water outlet 113 with the ozone water.

[0220] The water treatment device having the above structure can be said to have the following structure. That is, the functional part of the water treatment device A4 of this embodiment is an ozone water generator 240 including electrodes for generating ozone, and the ozone water generator 240 is provided at a position upstream of the mist generating unit 60 in the mist generating flow path 41 .

[0221] According to such a configuration, since the mist generating unit 60 atomizes and sprays the ozone water generated by the ozone water generating unit 240, it is expected that the effect of ozone water, namely, sterilization and antibacterial effects, can be brought to the main body 210 of the water treatment device A4 and its surroundings.

[0222] In addition, the water treatment device A4 of this embodiment has a branch portion 123 in the mist generating flow path 41 upstream of the mist generating portion 60, and the branch portion 123 branches off the ozone water flow path (functional water flow path 28) toward the ozone water outlet (functional water spray outlet 114) from the mist generating flow path 41.

[0223] According to such a structure, an ozone water outlet (functional water outlet 114) is provided to take out water, and for example, ozone water can be used as water for rinsing the mouth, thereby expecting effects such as oral care and periodontal disease prevention.

[0224] The mist generation flow path 41 is configured to cause excess water that has not flowed into the mist generation unit 60 to flow back to the ozone water flow path (functional water flow path 28 ) downstream of the mist generation unit 60 .

[0225] According to such a configuration, since the surplus water can also be taken in from the ozone water outlet (functional water outlet 114), the generated ozone water can be used without waste.

[0226] In addition, the mist outlet 27 is provided on the lower surface and / or the side surface of the main body.

[0227] According to such a structure, the mist outlet 27 is provided on the side as in the present embodiment, so that the rod 13 that the user touches can be effectively sterilized. In addition, when the mist outlet is provided on the lower surface of the main body 210, the atomized ozone water can be sprayed toward the drain of the washing basin, etc., and the washing basin can be kept clean.

[0228] [Variation of the Fourth Embodiment]

[0229] Next, a modification of the fourth embodiment of the water treatment device of the present disclosure will be described.

[0230] Fig.18 Schematic diagram showing a simplified internal structure of a water treatment device A4 according to a modified example of the fourth embodiment. Fig.17 The electrical structure of a water treatment device A4 according to a modified example of the fourth embodiment will be described.

[0231] In the water treatment device A4 of this modified example, the switching valve 117 provided in the central part 220 of the main body is a switching valve that switches the flow path into four paths. By switching the switching valve 117, the following paths can be switched: first, the raw water flow path 14 toward the raw water outlet 12; second, the purified water flow path 31 toward the purified water unit 30; third, the functional water flow path 48 toward the ozone water generating unit 240; and fourth, a flow path that receives ozone water discharged from the ozone water generating unit 240 via the ozone water circulation path 49 and transports it to the purified water flow path 31, and discharges the circulated ozone water from the purified water outlet 113.

[0232] The control unit 50 obtains the selected flow path information based on the rotational position of the rod 13 based on the electrical signal of the angle sensor 33 provided in the switching valve 117. Furthermore, the control unit 50 controls the operation of the electric switching valve 38 provided downstream of the ozone water generating unit 240 based on the obtained flow path information.

[0233] Furthermore, the flow path toward the purified water outlet 113 through the water purification unit 30 and the flow path through the ozone water generating unit 240 are separated and independent through the switching valve 117 .

[0234] A branch portion is provided in the mist generation flow path 41 toward the mist generation unit 60 downstream of the ozone water generation unit 240, which branches from the mist generation flow path 41 into a functional water flow path 28 toward the ozone water outlet, i.e., the functional water outlet 114, and the branch portion is configured to be able to switch the flow path by an electric switching valve 38. The switching valve 38 switches the flow path to the flow path that is connected to the functional water outlet 114 and supplies functional water to the mist generation unit 60 and the ozone water circulation path 49 in accordance with the driving of the motor 39 based on the command of the control unit 50.

[0235] When the purified water flow path 31 is selected as the flow path of the switching valve 117 according to the rotation position of the lever 13 , raw water received from the faucet 101 passes through the water purification unit 30 , and the user can take out purified water through the purified water outlet 113 .

[0236] In addition, when the functional water flow path 48 is selected as the flow path of the switching valve 117 according to the rotation position of the rod 13, the ozone water generating unit 240 and the mist generating unit 60 are driven based on the control of the control unit 50. At this time, the switching valve 38 is switched so that the outlet side flow path of the ozone water generating unit 240 is connected to the mist generating flow path 41 and the functional water flow path 28.

[0237] The ozone water reaching the functional water flow path 28 through the ozone water generator 240 can be taken out from the functional water outlet 114. The ozone water reaching the mist generator 60 through the ozone water generator 240 is atomized in the mist generator 60 and sprayed from the mist outlet 27.

[0238] In addition, when the ozone water circulation path 49 is selected as the flow path of the switching valve 117 according to the rotation position of the rod 13, the ozone water generating unit 240 and the mist generating unit 60 are driven based on the control of the control unit 50, and the switching valve 38 is switched to communicate with the ozone water circulation path 49. In addition, the switching valve 38 may not allow all of the ozone water that has passed through the ozone water generating unit 240 to flow into the ozone water circulation path 49.

[0239] In addition, the ozone water that has passed through the switching valve 117, the functional water flow path 48, the ozone water generating unit 240 and the ozone water circulation path 49 returns to the switching valve 117 again, enters the purified water flow path 31, and is discharged from the purified water outlet 113 through the purified water unit 30. Thus, the purified water unit 30 and the purified water flow path 31 are sterilized by the ozone water.

[0240] The water treatment device A4 of the modified example having the above-described structure can be said to have the following structure: That is, the functional water flow path 28 is configured to reflux at least a part of the ozone water to the clean water flow path 31 .

[0241] According to such a configuration, the purified water flow path can be sterilized and disinfected by utilizing the effect of ozone water.

[0242] [Fifth Embodiment]

[0243] Next, a fifth embodiment of the water treatment device of the present disclosure will be described.

[0244] In the embodiments described below, the same names or the same reference numerals are used for configurations that are common to or correspond to those in the first, second, third, and fourth embodiments, and description of duplicate contents will be appropriately omitted.

[0245] The appearance of the water treatment device A5 of this embodiment is Fig.14 The fourth embodiment shown is the same as the fourth embodiment, but the mist sprayed from the mist outlet 27 is hypochlorite water, which is different from the fourth embodiment. Fig.15 The internal structure of the main body 310 will be described.

[0246] The hypochlorite water generating unit 340 is a functional unit for generating hypochlorite water as functional water. The hypochlorite water generating unit 340 is composed of a hollow, substantially box-shaped electrolytic cell formed in a watertight state. An electrode serving as a cathode and an electrode serving as an anode are arranged inside the electrolytic cell. The electrolytic cell is a one-chamber type electrolytic cell without a diaphragm separating the anode side and the cathode side. Each electrode is electrically connected to the control unit 50.

[0247] A salt adding cylinder 75 as a salt adding portion is provided upstream of the hypochlorite water generating portion 340. The salt adding cylinder 75 has, for example, a funnel shape whose lower end is connected to the flow path, and a cover portion covering the upper portion is provided on the upper surface of the main body portion 310. The purified water that has passed through the water purification portion 30 reaches the hypochlorite water generating portion 340 via the salt adding cylinder 75. A chlorine source such as salt is added to the salt adding cylinder 75, and the salt contacts the purified water to dissolve the electrolytic substance, thereby facilitating electrolysis in the electrolytic cell.

[0248] A branch portion 123 is provided in the middle of the mist generation passage 41 connected to the mist generation unit 60, which is downstream of the hypochlorite water generation unit 340. The branch portion 123 branches into a functional water passage 28 from the mist generation passage 41 toward the functional water discharge port 114 upstream of the mist generation unit 60.

[0249] A return path 68 for returning excess hypochlorite water not used in the mist generating section 60 to the functional water flow path 28 is formed in the mist generating flow path 41 at a position downstream of the mist generating section 60 .

[0250] The hypochlorite water that has passed through the hypochlorite water generating unit 340 and reached the mist generating unit 60 is atomized and sprayed from the mist outlet 27 provided at a position close to the rod 13 on the side of the main body central unit 220 (see Fig.14The sprayed hypochlorite water is applied to the rod 13 that the user touches with his hands, and the rod 13 can be kept clean by utilizing the sterilization effect of the hypochlorite water.

[0251] The water treatment device having the above structure can be said to have the following structure. That is, the functional part of the water treatment device A5 of this embodiment is a hypochlorite water generating unit 340 including electrodes for generating hypochlorite water, and an input unit (salt adding cylinder 75) for inputting salt is provided upstream of the hypochlorite water generating unit 340.

[0252] According to such a configuration, since the mist generating unit 60 atomizes and sprays the hypochlorite water generated by the hypochlorite water generating unit 340, it is expected that the hypochlorite water effect, namely, sterilization and antibacterial effect, etc., can be brought to the main body 210 of the water treatment device A5 and its surroundings.

[0253] In addition, in order to improve the efficiency of electrolysis and the concentration of effective components in functional water, the salt input unit may be provided in the water treatment device A1 having the hydrogen water generating unit 40 as a functional unit. In this case, the water purification unit 30 is provided downstream of the functional unit, so that the chlorine odor from the remaining chlorine can be removed from the hydrogen water taken out as drinking water.

[0254] [Modifications of the First to Third Embodiments]

[0255] Next, modifications of the first to third embodiments of the water treatment device of the present disclosure will be described. Figures 19 to 21 A modification of the backflow blocking portion is described. Fig.21 is Fig. 20 An enlarged view of the portion indicated by symbol D in FIG.

[0256] In this variation, if Fig.19 As shown, in place of the check valve 42 shown in the first to third embodiments, a ring portion 76 having a flow path in a hairpin shape is used as a backflow prevention portion.

[0257] In addition, if Fig. 20 As shown, in the mist generation flow path 41, at least the downstream side of the backflow prevention portion is provided with an inclined portion 41a with the discharge port facing downward, so that the excess water can be easily discharged. In this case, the mist generating portion 60 is provided in the middle of the inclined portion 41a.

[0258] In addition, as a backflow prevention portion, the mist generation flow path 41 is formed into a ring portion 77 that connects the two inclined portions 41a and the inclined portion 41b, which are the inclined portions 41b on the upstream side and the inclined portions 41a on the downstream side. In addition, a conical valve 78 for air intake is provided at the top of the ring portion 77. The conical valve 78 performs an opening and closing operation according to the change in the pressure in the flow path. The conical valve 78 is configured to open when the mist generation flow path 41 becomes a negative pressure, so that the external air flows into the mist generation flow path 41, and to close when the internal pressure rises.

[0259] The water treatment device of the modified example having the above-described structure can be said to have the following structure: That is, the mist generation flow path 41 has the inclined portion 41a which is inclined downward toward the drain port 43, and the mist generating unit 60 is provided in the middle of the inclined portion 41a.

[0260] According to such a structure, the excess water which has not flowed into the mist generating unit 60 flows down along the inclined portion 41a and is quickly discharged from the flow path.

[0261] In addition, an air intake valve (cone valve 78 ) is provided in the mist generation flow path 41 at a position upstream of the mist generating unit 60 .

[0262] According to such a structure, even when the remaining water that has not flowed into the mist generating unit 60 cannot fall along the inclined portion 41a due to surface tension, the remaining water can be smoothly sent toward the discharge port by taking air into the flow path from the outside with the air intake valve in the open position.

[0263] [Modifications of the First to Fifth Embodiments]

[0264] Modifications of the first to fifth embodiments of the water treatment device of the present disclosure will be described. Fig. 22 The electrical structure examples of the water treatment device of the modified examples of the first embodiment to the fifth embodiment are shown. In addition, in these electrical structures, the power plug 29 connected to the commercial power supply can of course be replaced with the power supply unit 80. According to the structure of each embodiment, Fig. 22 The structure shown is changed.

[0265] First, a first modification example of the first to fifth embodiments of the water treatment device of the present disclosure will be described.

[0266] In the first to fifth embodiments, the switching valve 16 provided in the main body 10, 110, 210 is used by the user to rotate the lever 13 at a predetermined angle to switch the flow path between the raw water flow path 14 and the purified water flow path 31. In contrast, in this modification, instead of the manual switching valve 16, an electric switching valve 118 and a push button switch 83 electrically connected to the control unit 50 are provided.

[0267] The push button switch 83 can be disposed on the main body 10, 110, 210, 310 or the housing 20, 120 separated from the main body 10, 110 according to the arrangement of the control unit 50. The user switches the flow path of the switching valve 118 by pressing the push button switch 83.

[0268] Next, a second modified example of the first to fifth embodiments of the water treatment device of the present disclosure will be described.

[0269] In the first modification, a pressure sensor 82 is provided instead of the flow sensor 32. The pressure sensor 82 is electrically connected to the control unit 50, and outputs an electrical signal corresponding to the pressure applied to the purified water flow path 31 to the control unit 50. The control unit 50 calculates the life until replacement of the filter cartridge constituting the water purification unit 30 based on the input pressure signal, for example, and displays it on the flow display unit 121.

[0270] Next, a third modified example of the first to fifth embodiments of the water treatment device of the present disclosure will be described.

[0271] In the third modification, as the mist generating unit 60, a method is adopted in which the lower end of the impregnated body is immersed in water and the water sucked into the impregnated body is converted into mist by centrifugal force instead of the ultrasonic method.

[0272] The impregnated body has, for example, a funnel shape, and is configured to rotate by being driven by a motor 85 electrically connected to the control unit 50 .

[0273] In addition, as the atomizing mechanism, an electrostatic atomization method may be adopted in which a needle-shaped electrode having a longitudinal groove is immersed in water and a high voltage is applied to the needle-shaped electrode to generate atomization. In this case, a predetermined voltage is applied to the needle-shaped electrode electrically connected to the control unit 50 to achieve atomization.

[0274] Next, a fourth modified example of the first to fifth embodiments of the water treatment device of the present disclosure will be described.

[0275] In the fourth modification, when driving the mist generating unit 60 , the control unit 50 adjusts the driving timing according to the amount of water supplied to the purified water flow path 31 .

[0276] More specifically, when the user presses the function water button F1 or the mist button F2, the control unit 50 drives the mist generating unit 60 not at the time of the pressing but after a predetermined flow rate has flowed.

[0277] The control unit 50 includes a timer 53. For example, when a signal indicating that the mist button F2 has been pressed is input, the control unit 50 transmits a drive signal to the mist generating unit 60 after a time preset by the timer 53 has elapsed.

[0278] In addition, the control unit 50 is connected to a flow sensor 32 or a pressure sensor 82, and can detect the water flow state to the clean water flow path 31 based on the electrical signal from the sensor. The control unit 50 sends a drive signal to the mist generating unit 60 after a preset time has passed from the water flow detection signal input from the sensor according to the operation of the timer 53. The setting time of the timer 53 is set in consideration of the structure and flow path length of the flow path from the connection position of the sensor to the functional water reaching the mist generating unit 60, which is sandwiched in the clean water flow path 31. Thus, after the functional water required for atomization is fully supplied to the mist generating unit 60, the control unit 50 drives the mist generating unit 60.

[0279] The water treatment device of the modified example having the above structure can be said to have the following structure: that is, it has a detection unit (flow sensor 32, pressure sensor 82) for detecting the water flow state of the water purification unit 30 or the functional unit 40, 140, 240, 340, and the control unit 50 drives the mist generating unit 60 after a predetermined time has passed since the detection unit detects the water flow state.

[0280] In addition, although the flow sensor 32 or the pressure sensor 82 is used as the detection unit, the present invention is not limited thereto. In addition, the arrangement of the detection unit can be freely changed as long as it is in the flow path upstream of the mist generating unit 60 .

[0281] According to such a configuration, since the mist generating unit 60 is driven after a predetermined time has passed since the detecting unit detected the water flow state, it is possible to prevent the mist generating unit 60 from idling.

[0282] When an ultrasonic method is adopted as the atomizing mechanism of the mist generating unit 60, by preventing idling, damage to components such as an ultrasonic vibrator can be prevented, and the life of the device can be extended.

[0283] The description of each embodiment described above is an example of the present invention, and the present invention is not limited to the above embodiment. Therefore, even outside the above embodiment, various changes can be made according to design, etc. as long as they do not depart from the scope of the technical idea of ​​the present invention. In addition, the structure of each embodiment described above and the structure of the modified example can be appropriately combined.

[0284] In addition, the water treatment device of the present invention can also be applied to a central water treatment device. That is, it can be applied to a water treatment device in which a large-capacity water purification unit is set at the inflow part of the raw water (tap water) piped to the individual's home, and the purified water filtered in this part is supplied to each room (bathroom, washroom, kitchen, etc.) on the downstream side.
