Description

  The present invention relates to an electrolyzed water generating apparatus that generates electrolyzed water by electrolyzing water.

  There is known an electrolyzed water generating apparatus capable of generating electrolyzed hydrogen water in which hydrogen molecules are dissolved by electrolyzing water. In recent years, electrolyzed water generators for household use have become widespread so that electrolyzed hydrogen water can be easily consumed in daily life. For example, Patent Document 1 discloses an electrolyzed water generating device including a detachable water purification cartridge for purifying tap water and an electrolysis tank for electrolyzing water purified by the water purification cartridge.

Japanese Patent No. 4613834

  In the electrolyzed water generating apparatus described in Patent Document 1, a switching unit for switching a water channel is attached to a faucet of a faucet that supplies raw water. The switching unit selectively switches to a water channel that directly discharges raw water from a water outlet provided in the switching unit or a water channel that supplies raw water to the main body of the electrolyzed water generating device. For example, when discharging warm water, the former water channel is selected. On the other hand, when the latter water channel is selected, the electrolyzed water purified by the water purification cartridge and electrolyzed by the electrolytic cell is returned to the switching unit and discharged from the water outlet provided in the switching unit.

  Since the switching unit requires a corresponding size for switching the water channel, it is difficult to reduce the size, and the aesthetics of the kitchen may be impaired. Moreover, although the switching unit in recent years has been subjected to various aesthetic treatments, there is a risk of lack of affinity with faucets or the like that are designed uniformly with each kitchen.

  When the switching unit is discarded in the electrolyzed water generating device described in Patent Document 1, when hot water is supplied from the faucet to the electrolyzed water generating device, the hot water flows into the water purification cartridge. For this reason, the impurities already filtered out by the water purification cartridge may be dissolved in the hot water and discharged from the apparatus. The same applies to the case where the user operates the switching unit incorrectly.

  The present invention has been devised in view of the above circumstances, and a switching unit that is mounted on a faucet of a faucet by allowing the supplied raw water to be discharged from a water outlet without purifying it with a water purification cartridge. The main purpose is to provide an electrolyzed water generator that eliminates the need for water.

  The present invention provides an electrolytic cell that electrolyzes water to generate electrolyzed water, a water purification cartridge that is provided upstream or downstream of the electrolytic cell and purifies water, and discharges electrolyzed water generated by the electrolytic cell. An electrolyzed water generating device comprising a water outlet, a first main water channel provided upstream of the water purification cartridge, and a second main water channel provided downstream of the water purification cartridge and connected to the water outlet. A sub-water channel that branches off from the first main water channel, bypasses the water purification cartridge and is connected to the second main water channel, and a first water channel that guides water supplied to the first main water channel to the sub-water channel And a switching valve, wherein water bypassing the water purification cartridge can be discharged from the water outlet.

  In the electrolyzed water generating apparatus according to the present invention, it is preferable that the first main water channel has a connecting means connected to a hot and cold water mixing faucet outside the apparatus.

  In the electrolyzed water generating apparatus according to the present invention, a water temperature sensor that detects a temperature of water flowing through the first main water channel, and a control unit that controls the water channel switching valve based on a signal output from the water temperature sensor. It is desirable to further provide.

  In the electrolyzed water generating apparatus according to the present invention, it is preferable that the sub-water channel is connected to the second main water channel, bypassing the electrolyzer.

  In the electrolyzed water generating device according to the present invention, it is preferable that the electrolyzed water generating device further includes a second water channel switching valve that guides water flowing through the sub water channel to the water outlet.

  In the electrolyzed water generating apparatus according to the present invention, the water purification cartridge is detachable from an apparatus main body of the electrolyzed water generating apparatus, and further includes attachment / detachment detection means for detecting an attachment / detachment state of the water purification cartridge, and the control It is desirable that the unit controls the water channel switching valve based on a signal output from the attachment / detachment detection means.

  The electrolyzed water generating device of the present invention includes: a first main water channel provided upstream of the water purification cartridge; a second main water channel provided downstream of the water purification cartridge and connected to the water outlet; A sub-water channel that branches from one main water channel, bypasses the water purification cartridge and is connected to the second main water channel, and a first water channel switching valve that guides water supplied to the first main water channel to the sub-water channel. When the first water channel switching valve switches the water channel, the water supplied to the first main water channel flows into the sub-water channel, bypasses the water purification cartridge, and is discharged from the water outlet. As a result, the raw water supplied to the electrolyzed water generating device can be discharged from the water outlet without purifying it with the water purification cartridge, and the aesthetics of the kitchen can be improved without the need for a switching unit attached to the faucet of the faucet. . Further, since the operation of the switching unit is not necessary, the operation of the electrolyzed water generating device can be simplified.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a kitchen in which the electrolyzed water generating device 1 of the present embodiment is installed. The electrolyzed water generating apparatus 1 according to the present embodiment is installed adjacent to a water source such as a hot-water mixed tap 100 around the sink 200.

  The hot and cold water mixing tap 100 supplies raw water to the electrolyzed water generator 1. As the raw water, tap water is generally used, but well water, ground water, and the like can be used. The raw water supplied from the hot and cold water mixing tap 100 includes hot water heated to a desired temperature by heating means (not shown) such as a water heater, in addition to the above-mentioned tap water at room temperature.

  The electrolyzed water generating device 1 includes a device main body 2, a water supply pipe 21, a water discharge pipe 22, a drain pipe 23, and an operation means 24. The water supply pipe 21, the water discharge pipe 22 and the drain pipe 23 extend from the apparatus main body 2.

  The water supply pipe 21 is connected to the faucet 101 of the hot and cold water mixing faucet 100 through connection means 21 a provided at the tip thereof. The faucet 101 is provided at the tip of a faucet pipe that extends in an arm shape from the main body of the hot and cold water mixing faucet 100. The water supply pipe 21 may be directly connected to the main body of the hot and cold water mixing tap 100. The water supply pipe 21 guides the raw water supplied from the hot / cold water mixing tap 100 to the apparatus main body 2.

  The water discharge pipe 22 discharges the electrolyzed water generated in the apparatus main body 2 of the electrolyzed water generating apparatus 1. For example, the water discharge pipe 22 discharges electrolytic hydrogen water generated in the apparatus main body 2. A water outlet 22 a is provided at the tip of the water discharge pipe 22. The water discharge port 22 a discharges water from above the sink 200. In order to improve the usability of the electrolyzed water generating apparatus 1, the water discharge pipe 22 may be rotatably mounted on the apparatus main body 2.

  The drain pipe 23 discharges the electrolyzed water generated as a secondary within the apparatus main body 2 of the electrolyzed water generating apparatus 1. For example, the water discharge pipe 22 discharges the electrolytic oxygen water in which oxygen that is generated as a secondary component when the electrolytic hydrogen water is generated in the apparatus main body 2 is dissolved. The tip of the drain pipe 23 is disposed in the sink 200.

  The operation means 24 is provided in the apparatus main body 2 of the electrolyzed water generating apparatus 1. The operation means 24 includes a switch operated by a user, a touch panel for detecting capacitance, or the like (not shown). The operation means 24 is operated by the user in order to switch the operation mode of the electrolyzed water generating apparatus 1. The operation means 24 outputs an electrical signal corresponding to the user's operation to the control means 7 (see FIG. 3) of the electrolyzed water generating apparatus 1. The operation mode of the electrolyzed water generating apparatus 1 includes “electrolyzed hydrogen water mode”, “electrolyzed oxygen water mode”, “purified water mode”, “raw water mode”, and the like.

  The electrolytic hydrogen water mode is a mode in which electrolytic hydrogen water is generated in the apparatus main body 2 and discharged from the water discharge port 22a. The electrolyzed oxygen water generated as a secondary in the electrolytic hydrogen water mode is discharged from the drain pipe 23. The electrolytic oxygen water mode is a mode in which electrolytic oxygen water is generated in the apparatus main body 2 and discharged from the water outlet 22a. The electrolytic hydrogen water that is generated as a secondary in the electrolytic oxygen water mode is discharged from the drain pipe 23.

  The purified water mode is a mode in which purified water purified in the apparatus main body 2 is generated and discharged from the water outlet 22a. The raw water mode is a mode in which the raw water supplied from the hot / cold water mixing faucet 100 is allowed to pass through the apparatus main body 2 and discharged from the spout 22a as raw water. Hereinafter, in this specification, water that has not passed through the water purification cartridge 3 is defined as “raw water”. Therefore, the raw water includes hot water supplied from the hot and cold water mixing tap 100 in addition to room temperature water. The raw water discharged in the raw water mode is used, for example, for washing dishes.

  FIG. 2 shows a schematic configuration of the electrolyzed water generating apparatus 1. The electrolyzed water generating apparatus 1 includes a water purification cartridge 3 that purifies water and an electrolyzer 4 that electrolyzes water to generate electrolyzed water.

  The purified water cartridge 3 generates purified water by filtering the raw water supplied to the electrolyzed water generating device 1. The water purification cartridge 3 of the present embodiment is configured to be detachable from the apparatus main body 2. Thereby, the water purification cartridge 3 that has reached the end of its life due to use or over time can be replaced with a new water purification cartridge 3.

  The water purification cartridge 3 is provided upstream of the electrolytic cell 4. Therefore, the water purified by the water purification cartridge 3 is supplied to the electrolytic cell 4.

  The electrolyzed water generating apparatus 1 includes a first main water channel 30 and a second main water channel 40. The first main water channel 30 is provided upstream of the water purification cartridge 3. The first main water channel 30 includes first main water channels 30a, 30b, and 30c. The water supply pipe 21 shown in FIG. 1 constitutes a part of the first main water channel 30. The first main water channel 30 guides the raw water supplied from the tap 101 to the water purification cartridge 3.

  The second main water channel 40 is provided downstream of the water purification cartridge 3. The second main water channel 40 includes second main water channels 40a, 40b, and 40c. The water discharge pipe 22 shown in FIG. 1 constitutes a part of the second main water channel 40. The second main water channel 40 guides the purified water flowing out from the purified water cartridge 3 to the water outlet 22a via the electrolytic cell 4 and the like.

  The electrolytic cell 4 has an anode chamber and a cathode chamber separated by a diaphragm. Each of the anode chamber and the cathode chamber is provided with a power feeder. The electrolytic hydrogen water is generated in the cathode chamber, and the electrolytic oxygen water is generated in the anode chamber. The configuration of the electrolytic cell 4 may be the same as, for example, a known electrolytic cell disclosed in JP-A-2015-176063. Therefore, in this specification, the detailed description regarding the electrolytic cell 4 is abbreviate | omitted.

  For example, a double crossline valve disclosed in Japanese Patent No. 5809208 may be provided on the upstream side and the downstream side of the electrolytic cell 4.

  The electrolyzed water generating apparatus 1 includes a sub-water channel 50 and a first water channel switching valve 5. The secondary water channel 50 branches from the first main water channel 30 and is connected to the second main water channel 40 by bypassing the water purification cartridge 3 and the electrolytic cell 4. The first water channel switching valve 5 is provided at a branch point of the sub water channel 50 from the first main water channel 30. The first water channel switching valve 5 guides the water supplied to the first main water channel 30 to the sub water channel 50. For example, a three-way valve driven by a motor or the like can be applied to the first water channel switching valve 5.

  In the electrolyzed water generating apparatus 1 in the initial state, the first main water channel 30b and the first main water channel 30c on the downstream side are communicated with each other by the first water channel switching valve 5, and the sub water channel 50 is closed. Along with this, the function of the secondary water channel 50 is invalidated. The first water channel switching valve 5 switches the water channel to connect the first main water channel 30b and the sub water channel 50, and closes the first main water channel 30c, thereby enabling the sub water channel 50. That is, the raw water supplied from the water supply pipe 21 flows into the sub-water channel 50 and is discharged from the water discharge port 22a after bypassing the water purification cartridge 3 and the electrolytic cell 4. As a result, the raw water supplied to the electrolyzed water generating device 1 can be discharged from the water discharge port 22a as it is without passing through the water purification cartridge 3.

  Therefore, even if warm water is supplied as raw water from the hot and cold water mixing tap 100 to the electrolyzed water generating apparatus 1, the hot water is purified by switching the water channel to the sub water channel 50 by the first water channel switching valve 5. The cartridge 3 can be detoured and discharged from the water outlet 22a. Therefore, the possibility that impurities already filtered out by the water purification cartridge 3 are dissolved in the hot water and discharged from the spout 22a together with the hot water is suppressed.

  Moreover, the switching unit attached to the faucet 101 of the hot and cold water mixing faucet 100 is unnecessary, and the aesthetics of the kitchen can be improved. Furthermore, since the operation of the switching unit becomes unnecessary, the operation of the electrolyzed water generating device 1 can be simplified.

  FIG. 3 shows an electrical configuration of the electrolyzed water generating apparatus 1. The electrolyzed water generating apparatus 1 has a water temperature sensor 6 and a control means 7.

  As shown in FIG. 2, the water temperature sensor 6 is provided in the first main water channel 30 on the upstream side of the first water channel switching valve 5. By the water temperature sensor 6 and the first water channel switching valve 5, the first main water channel 30 is divided into first main water channels 30a, 30b, and 30c. The first main water channel 30 a is disposed upstream of the water temperature sensor 6 and is connected to the water supply pipe 21. The first main water channel 30 b is disposed downstream of the water temperature sensor 6 and upstream of the first water channel switching valve 5. The first main water channel 30 c is arranged downstream of the first water channel switching valve 5.

  The water temperature sensor 6 detects the temperature of the water flowing through the first main water channel 30 and outputs a corresponding electrical signal to the control means 7.

  The control means 7 controls each part of the electrolyzed water generating apparatus 1. For example, according to the operation mode of the electrolyzed water generating apparatus 1 switched by the operation unit 24, the control unit 7 controls the electrolyzer 4 and the first water channel switching valve 5.

  The control means 7 controls the first water channel switching valve 5 based on the signal output from the water temperature sensor 6 or the like. Thereby, according to the temperature of the water which flows through the 1st main water channel 30, the water channel in the electrolyzed water generating apparatus 1 is switched.

  The first water channel switching valve 5 in the initial state closes the sub water channel 50 and allows the first main water channel 30b and the first main water channel 30c to communicate with each other. Therefore, the raw water that has passed through the water temperature sensor 6 is supplied to the water purification cartridge 3 via the first main water channel 30c. When the hot water is supplied from the hot and cold water mixing tap 100 and the water temperature detected by the water temperature sensor 6 rises to a predetermined threshold value (for example, 35 ° C.) or higher, the control means 7 controls the first water channel switching valve 5. To switch the water channel downstream of the first water channel switching valve 5 from the first main water channel 30 c to the sub water channel 50. Thereby, the warm water above the threshold flows into the sub-water channel 50 and bypasses the water purification cartridge 3 and the electrolytic cell 4. And when the water temperature detected by the water temperature sensor 6 becomes less than the said threshold value, the control means 7 operates the 1st water path switching valve 5, and switches a water path. Thereby, the secondary water channel 50 is closed again, and the first main water channel 30b and the first main water channel 30c are communicated.

  A second water channel switching valve 8 is provided in the second main water channel 40 of the electrolyzed water generator 1. It is provided between the electrolytic cell 4 and the water discharge port 22a. For example, a three-way valve driven by a motor or the like can be applied to the second water channel switching valve 8. The second main water channel 40 is divided into second main water channels 40a, 40b, and 40c by the electrolytic cell 4 and the second water channel switching valve 8. The second main water channel 40 a is arranged upstream of the electrolytic cell 4. The second main water channel 40 b is disposed downstream of the electrolytic cell 4 and upstream of the second water channel switching valve 8. The second main water channel 40 c is arranged downstream of the second water channel switching valve 8 and is connected to the water discharge pipe 22.

  The operation of the second water channel switching valve 8 is controlled by the control means 7. The control means 7 controls the second water channel switching valve 8 in synchronization with the first water channel switching valve 5. The second water channel switching valve 8 in the initial state closes the sub water channel 50 and allows the second main water channel 40b and the second main water channel 40c to communicate with each other. When the first water channel switching valve 5 switches the water channel from the first main water channel 30c to the sub water channel 50, the second water channel switching valve 8 closes the second main water channel 40b, and the sub water channel 50 and the second main water channel 40c. To communicate. Thereby, it is prevented that the water which flowed through the subwater channel 50 flows backward into the electrolytic cell 4 and the water purification cartridge 3.

  The electrolyzed water generating apparatus 1 further includes attachment / detachment detection means for detecting the attachment / detachment state of the water purification cartridge 3. In this embodiment, the communication means 9 which communicates with the water purification cartridge 3 is applied as attachment / detachment detection means.

  The communication means 9 is controlled by the control means 7 and communicates with the RFID tag 3 a built in the water purification cartridge 3. For example, the communication means 9 communicates with the RFID tag 3a and reads identification information unique to the water purification cartridge 3 stored in the RFID tag 3a or writes information related to the use history of the water purification cartridge 3 into the RFID tag 3a. .

  The communication unit 9 periodically communicates with the RFID tag 3 a and feeds back the result to the control unit 7. When the water purification cartridge 3 is removed from the apparatus main body 2 of the electrolyzed water generating apparatus 1 when the water purification cartridge 3 is replaced, the communication between the communication means 9 and the RFID tag 3a is interrupted. Therefore, the control means 7 can detect that the water purification cartridge 3 is removed from the apparatus main body 2 by monitoring the communication between the communication means 9 and the RFID tag 3a.

  As the attachment / detachment detection means for detecting the attachment / detachment state of the water purification cartridge 3, configurations other than the communication means 9 can be applied. For example, in addition to a configuration that physically contacts the casing of the water purification cartridge 3 to detect the attachment / detachment state of the water purification cartridge 3, an opening / closing state of the cover of the apparatus main body 2 that is opened and closed when the water purification cartridge 3 is attached / detached is detected. Configurations and the like can be applied.

  FIG. 4 shows the operation of the control means 7 when water is passed through the electrolyzed water generator 1. The control means 7 confirms the attachment / detachment state of the water purification cartridge 3 (S1). When the water purification cartridge 3 is not mounted (N in S1), the control means 7 operates the first water channel switching valve 5 and the second water channel switching valve 8 to operate the first water channel switching valve 5 and the second water channel switching valve 8. Is switched to the secondary water channel 50 (S4), and water flow is started (S5). In S4, the first water channel switching valve 5 switches the water channel downstream of the first main water channel 30b from the first main water channel 30c to the sub water channel 50. Further, the second water channel switching valve 8 switches the water channel upstream of the second main water channel 40 c from the second main water channel 40 b to the sub water channel 50. Thereby, the water leak inside the apparatus main body 2 can be suppressed.

  When the water purification cartridge 3 is mounted (Y in S1), the control means 7 confirms the operation mode of the electrolyzed water generating device 1 (S2). When the operation mode is the raw water mode (Y in S2), the control means 7 operates the first water channel switching valve 5 and the second water channel switching valve 8, and the first water channel switching valve 5 and the second water channel switching valve 8 The water channel between is switched to the sub water channel 50 (S4), and water flow is started (S5). Thereby, the raw | natural water which detoured the water purification cartridge 3 is discharged from the spout 22a.

  When the operation mode is a mode other than the raw water mode (N in S2), the control means 7 confirms the water temperature detected by the water temperature sensor 6 (S3). When the water temperature is equal to or higher than the threshold value (Y in S3), the control means 7 operates the first water channel switching valve 5 and the second water channel switching valve 8 to operate the first water channel switching valve 5 and the second water channel switching valve 8; The water channel between is switched to the sub water channel 50 (S4), and water flow is started (S5). Thereby, the inflow of warm water to the water purification cartridge 3 is avoided.

  And when water temperature is less than the said threshold value (N in S3), the control means 7 does not switch the water channel between the 1st water channel switching valve 5 and the 2nd water channel switching valve 8 to the subwater channel 50, but water flow Is started (S5). Thereby, the purified water or electrolyzed water which passed through the water purification cartridge 3 is discharged from the water discharge port 22a.

  FIG. 5 shows the operation of each part of the electrolyzed water generating device 1 and the flow of water when discharging purified water or electrolyzed water from the water outlet 22a (N in S3 of FIG. 4). In the same figure, the region where water flows is indicated by thin hatching (hereinafter the same applies to FIG. 6). In this case, the first water channel switching valve 5 closes the sub water channel 50 to connect the first main water channel 30b and the first main water channel 30c, and the second water channel switching valve 8 closes the sub water channel 50 and the second main water channel 30c. The water channel 40b communicates with the second main water channel 40c. Thereby, raw water is supplied to the purified water cartridge 3, and the purified water produced | generated by passing the purified water cartridge 3 is discharged from the spout 22a.

  FIG. 6 shows the operation of each part of the electrolyzed water generating apparatus 1 and the flow of water when raw water is discharged from the water discharge port 22a (N in S1, Y in S2, or Y in S3). In this case, the first water channel switching valve 5 closes the first main water channel 30c, connects the sub water channel 50 and the first main water channel 30b, and the second water channel switching valve 8 closes the second main water channel 40b, The water channel 50 and the 2nd main water channel 40c are connected. Thereby, the raw | natural water which flows through the 1st main water channel 30b bypasses the water purification cartridge 3, and is discharged from the spout 22a.

  FIG. 7 shows a schematic configuration of an electrolyzed water generating device 1 </ b> A that is a modification of the electrolyzed water generating device 1. The electrolyzed water generating apparatus 1A is different from the electrolyzed water generating apparatus 1 in that the second water channel switching valve 8 is disposed between the water purification cartridge 3 and the electrolytic tank 4. In the electrolyzed water generating apparatus 1A, the configuration of the electrolyzed water generating apparatus 1 can be appropriately adopted for a portion not described below.

  In the electrolyzed water generating apparatus 1 </ b> A, raw water that bypasses the water purification cartridge 3 through the auxiliary water channel 50 flows into the electrolyzer 4. Therefore, electrolyzed water obtained by electrolyzing raw water can be generated and discharged from the water discharge port 22a.

  FIG. 8 shows a schematic configuration of an electrolyzed water generating device 1B which is another modified example of the electrolyzed water generating device 1. The electrolyzed water generating device 1 </ b> B is different from the electrolyzed water generating device 1 in that a water purification cartridge 3 is provided downstream of the electrolyzer 4. Accordingly, the first main water channel 30 c is arranged downstream of the first water channel switching valve 5 and upstream of the electrolytic cell 4, and the first main water channel 30 d is arranged downstream of the electrolytic cell 4. The second main water channel 40 a is disposed downstream of the water purification cartridge 3 and upstream of the second water channel switching valve 8. In the electrolyzed water generating apparatus 1B, the configuration of the electrolyzed water generating apparatus 1 can be appropriately adopted for portions that are not described below.

  In the electrolyzed water generating apparatus 1 </ b> B, the electrolyzed hydrogen water or the electrolyzed oxygen water generated in the electrolyzer 4 is purified by the water purification cartridge 3. Therefore, only the electrolyzed water discharged from the water discharge port 22a is purified, and the electrolyzed water discharged from the drain pipe 23 is not purified. Therefore, the water flow rate of the water purification cartridge 3 can be reduced.

  In the electrolyzed water generating apparatus 1 </ b> B, the first water channel switching valve 5 may be disposed between the electrolyzer 4 and the water purification cartridge 3. In this case, the raw water electrolyzed by the electrolytic cell 4 bypasses the water purification cartridge 3 and is discharged from the water discharge port 22a.

  As mentioned above, although the electrolyzed water generating apparatus 1 of this invention was demonstrated in detail, this invention is changed and implemented in various aspects, without being limited to said specific embodiment. That is, the electrolyzed water generating apparatus 1 includes at least an electrolyzer 4 that electrolyzes water to produce electrolyzed water, a water purification cartridge 3 that is provided upstream or downstream of the electrolyzer 4 and purifies water, and the electrolyzer 4.
