The hydrogen dissolving device 20 is provided in the upper door portion 1 a of the refrigerator 1. The water supplied to the hydrogen dissolving device 20 is cooled in the refrigerator compartment 10. Therefore, according to the refrigerator 1 of this invention, it becomes possible to produce | generate and provide the cold hydrogen water at any time according to a user's request, and usability improves.

  The refrigerator compartment 10 is provided with a water storage tank 19 as a water storage means for storing water. The water storage tank 19 stores water replenished by the user. The water stored in the water storage tank 19 is cooled by the cold air in the refrigerator compartment 10 and becomes cold water. The form of the water storage means is not limited to the water storage tank 19. For example, instead of the water storage tank 19, the water storage means may be configured by a pipe or the like meandering near the inner wall of the refrigerator compartment 10 or near the evaporator 15.

  A water supply channel 19 a is provided between the water storage tank 19 and the hydrogen dissolving device 20. The water supply channel 19 a is connected to the hydrogen dissolving device 20. The water supply channel 19 a supplies cold water stored in the water storage tank 19 to the hydrogen dissolving device 20. Thereby, cold hydrogen water can be generated by the hydrogen dissolving apparatus 20.

  Instead of or in addition to the water storage tank 19, raw water such as tap water may be directly supplied to the refrigerator 1. According to such a configuration, it is not necessary for the user to supply water to the water storage tank 19, and the usability of the refrigerator 1 is further enhanced.

  FIG. 4 shows an example of the hydrogen dissolving apparatus 20. The hydrogen dissolving device 20 includes an operation unit 21, a second control unit 22, a water purification cartridge 23, a hydrogen dissolving unit 24, and a water discharge unit 25.

  The operation part 21 is provided exposed on the upper door part 1a of the refrigerator 1, and is operated by the user. The operation unit 21 includes various buttons 21a (see FIG. 1) arranged to be exposed on the upper door 1a and switches (not shown) arranged on the back side of the buttons 21a.

Thereby, various information is shared between the 1st control part 18 and the 2nd control part 22, and the cooperation process is performed.

  The water purification cartridge 23 is connected to the water storage tank 19 through a water supply channel 19a. The water supply channel 19 a is appropriately provided with a pump for sending water from the water storage tank 19 to the hydrogen dissolving device 20. Cold water stored in the water storage tank 19 is supplied to the water purification cartridge 23. The cold water supplied to the water purification cartridge 23 is controlled by the water supply valve 23a.

  The water supply valve 23a is provided on the upstream side of the water purification cartridge 23 and is connected to the water supply channel 19a. As the water supply valve 23a, for example, an electromagnetic valve that opens and closes by a driving force of a solenoid can be used. The opening / closing operation of the water supply valve 23 a is managed by the second control unit 22. For example, when the button 21 a is operated by the user, the second control unit 22 opens the water supply valve 23 a based on the electrical signal output from the operation unit 21. Thereby, the cold water stored in the water storage tank 19 is supplied to the water purification cartridge 23.

  The water purification cartridge 23 purifies the cold water supplied from the water storage tank 19 and supplies it to the hydrogen dissolving part 24. The water purification cartridge 23 is configured to be detachable from the hydrogen dissolving device 20. The water purification cartridge 23 that has reached a predetermined water flow rate is replaced with a new water purification cartridge 23. The water purification cartridge 23 may be omitted. In this case, the water supply channel 19 a is directly connected to the hydrogen dissolving part 24.

  The hydrogen dissolving unit 24 generates hydrogen water by dissolving hydrogen in the cold water purified by the water purification cartridge 23. The hydrogen water generated by the hydrogen dissolving unit 24 is discharged from the water discharge unit 25.

  As shown in FIG. 1, the water discharger 25 is provided to be exposed on the front part of the hydrogen dissolving apparatus 20, that is, on the front surface of the main body part of the refrigerator 1 (in this embodiment, the upper door part 1 a). The user can ingest cold hydrogen water immediately by setting a cup or the like in the water discharger 25 and operating the button 21a. Therefore, hydrogen water can be ingested without releasing the upper door portion 1a of the refrigerator 1, and cold air in the refrigerator 1 can be prevented from flowing out.

  The hydrogen dissolving unit 24 includes a water inlet 30, an electrolytic tank 40, and a water outlet 50.

  The water inlet 30 communicates the water purification cartridge 23 and the electrolytic cell 40. The water inlet 30 includes a water supply pipe 31, a flow rate sensor 33, a branching portion 34, a flow rate adjustment valve 35, and a flow path switching valve 36.

  The water supply pipe 31 is connected to the water purification cartridge 23 and guides the water supplied from the water purification cartridge 23 to the electrolytic cell 40. The water supply pipe 31 is provided with a flow rate sensor 33.

  The flow sensor 33 detects the amount of water per unit time flowing into the electrolytic cell 40 by detecting the amount of water per unit time flowing through the water supply pipe 31. In the present embodiment, the flow rate sensor 33 is provided on the upstream side of the branching portion 34, so that the flow rate of water supplied to the first pole chamber 40A and the flow rate of water supplied to the second pole chamber 40B are The total, that is, the flow rate F of water supplied to the electrolytic cell 40 per unit time is detected.

  The branch part 34 branches the water supply pipe 31 into two directions of the water supply pipes 31a and 31b. The flow rate adjusting valve 35 is provided in the water supply pipe 31a on the upstream side of the first pole chamber 40A, and adjusts the amount of water flowing through the water supply pipe 31a. The flow path switching valve 36 switches the connection destination of the water supply pipes 31a and 31b. The second control unit 22 appropriately controls the flow rate adjustment valve 35 and the flow path switching valve 36 to limit the flow rate of water supplied to the first electrode chamber 40A or the flow rate of water supplied to the second electrode chamber 40B. Is done.

  The electrolytic cell 40 generates hydrogen gas by electrolyzing water. The electrolytic cell 40 includes a first power feeding body 41 and a second power feeding body 42, and a diaphragm 43 disposed between the first power feeding body 41 and the second power feeding body 42.

  As the first power supply body 41 and the second power supply body 42, for example, a structure in which a platinum plating layer is formed on the surface of a net-like metal such as an expanded metal made of titanium or the like is applied. Such a net-like first power supply body 41 and second power supply body 42 can distribute water to the surface of the diaphragm 43 while sandwiching the diaphragm 43, and promote electrolysis in the electrolytic cell 40. The platinum plating layer prevents the oxidation of titanium.

  A DC voltage is applied between the first power supply body 41 and the second power supply body 42. Thereby, the polarity of either an anode or a cathode is given to the 1st electric power feeder 41 and the 2nd electric power feeder 42. FIG.

  The diaphragm 43 divides the electrolytic chamber inside the electrolytic cell 40 into a first electrode chamber 40A on the first power feeder 41 side and a second electrode chamber 40B on the second power feeder 42 side. For the diaphragm 43, for example, a polytetrafluoroethylene (PTFE) hydrophilic film, a solid polymer material made of a fluororesin having a sulfonic acid group, and the like are appropriately used. The diaphragm 43 allows ions generated by electrolysis to pass through. The first power feeding body 41 and the second power feeding body 42 are electrically connected via the diaphragm 43.

The water supply pipes 31a and 31b are selectively connected to the first electrode chamber 40A or the second electrode chamber 40B by the flow path switching valve 36. The flow path switching valve 36 is driven by, for example, a motor,
The flow path in the water inlet 30 is switched. In the state shown in FIG. 4, the water supply pipe 31a is connected to the first polar chamber 40A, and the water supply pipe 31b is connected to the second polar chamber 40B. By supplying water to both the first electrode chamber 40A and the second electrode chamber 40B via the water supply pipes 31, 31a and 31b, and applying a DC voltage to the first power supply body 41 and the second power supply body 42, Water is electrolyzed inside the electrolytic cell 40. At this time, oxygen gas is generated in the electrolytic chamber on the anode side, and hydrogen gas is generated in the electrolytic chamber on the cathode side. Hydrogen gas generated in the electrolysis chamber on the cathode side is dissolved in water in the electrolysis chamber on the cathode side to generate electrolytic hydrogen water.

  For example, in the state shown in FIG. 4, the first power supply body 41 is charged with a positive charge, and the first electrode chamber 40A functions as an anode chamber. On the other hand, negative charge is charged in the second power feeder 42, and the second electrode chamber 40B functions as a cathode chamber. At this time, electrolytic hydrogen water is generated in the second electrode chamber 40B and electrolytic acid water is generated in the first electrode chamber 40A.

  A current detection unit 44 is provided on the current supply line between the first power feeder 41 and the second control unit 22. The current detection unit 44 may be provided in a current supply line between the second power feeder 42 and the second control unit 22. The current detection unit 44 detects the electrolytic current I supplied to the first power supply body 41 and the second power supply body 42, and outputs an electric signal corresponding to the value to the second control unit 22.

  For example, the second control unit 22 controls the DC voltage applied to the first power supply body 41 and the second power supply body 42 based on the electrical signals output from the flow sensor 33 and the current detection means 44. More specifically, the second controller 22 controls the first power feeder so that the electrolysis current I detected by the current detector 44 becomes a desired value according to the dissolved hydrogen concentration set by the user or the like. The DC voltage applied to 41 and the second power feeder 42 is feedback-controlled. For example, when the electrolysis current I is excessive, the second control unit 22 decreases the voltage, and when the electrolysis current I is excessive, the second control unit 22 increases the voltage. Thereby, the electrolysis current I supplied to the first power supply body 41 and the second power supply body 42 is appropriately controlled, and hydrogen water having a desired dissolved hydrogen concentration is generated in the electrolytic cell 40.

  Further, the second control unit 22 controls the polarity of the DC voltage applied to the first power supply body 41 and the second power supply body 42. For example, the second control unit 22 is provided with a polarity switching circuit (not shown) for switching the polarities of the first power feeding body 41 and the second power feeding body 42. The polarity of the DC voltage is switched according to, for example, the number of times of operation of the electrolytic cell 40, the operation time, or the integrated value of the amount of water passing through the electrolytic cell 40. By appropriately switching the polarities of the first power feeding body 41 and the second power feeding body 42, the adhesion of the scale inside the electrolytic cell 40 or the like is suppressed.

  In the present embodiment, the flow path switching valve 36 switches the flow path of the water inlet 30 in synchronization with the switching of the polarities of the first power supply body 41 and the second power supply body 42. Synchronization between the polarity switching and the flow path switching in the water inlet 30 is controlled by the second controller 22. That is, the second control unit 22 applies a driving voltage for switching the flow path to the motor of the flow path switching valve 36 in synchronization with the switching of the polarities of the first power feeding body 41 and the second power feeding body 42. Thereby, the water supply pipe 31a and the anode chamber are always connected, and the water supply pipe 31b and the cathode chamber are always connected. Therefore, a small amount of water limited by the flow rate adjusting valve 35 is supplied to the anode chamber. Thereby, irrespective of the polarity switching of the 1st electric power feeding body 41 and the 2nd electric power feeding body 42, it is possible to produce | generate a lot of electrolytic hydrogen water, suppressing the production amount of electrolytic acid water, and to improve the utilization efficiency of water. It becomes.

  In addition, the flow path switching valve 52 switches the flow path of the water outlet 50 in synchronization with the switching of the polarities of the first power supply body 41 and the second power supply body 42. Synchronization between the polarity switching and the flow path switching in the water outlet 50 is controlled by the second controller 22. That is, the second control unit 22 applies a driving voltage for switching the flow path to the motor of the flow path switching valve 52 in synchronization with the switching of the polarities of the first power feeding body 41 and the second power feeding body 42. Therefore, the anode chamber and the exhaust pipe 54 are always connected, and the cathode chamber and the water discharge pipe 53 are always connected. Thereby, it becomes possible to always flow the electrolytic hydrogen water generated in the cathode chamber into the water discharge pipe 53 regardless of the polarity switching of the first power supply body 41 and the second power supply body 42.

  Both the flow path switching valve 36 and the flow path switching valve 52 operate in synchronization with the polarity switching of the first power feeding body 41 and the second power feeding body 42. Therefore, by integrating or connecting the flow path switching valve 36 and the flow path switching valve 52 to each other, the flow path switching valve 36 and the flow path switching valve 52 can be driven by a single motor. And the structure of the hydrogen dissolving apparatus 20 and by extension the refrigerator 1 is simplified.

  In the present embodiment, the flow rate regulating valve 35 limits the flow rate of water supplied to the anode-side electrolysis chamber to be smaller than the flow rate of water supplied to the cathode-side electrolysis chamber. Thereby, more hydrogen water can be produced | generated from the water stored in the water storage tank 19, and the utilization efficiency of water is improved. For example, in the state shown in FIG. 4, the oxygen gas generated by electrolysis in the first electrode chamber 40A on the anode side is not completely dissolved in the electrolyzed water in the first electrode chamber 40A, and the first electrode chamber is in a gaseous state. It is discharged from 40A.

  Furthermore, in this case, the flow rate of water supplied to the anode-side electrolysis chamber limited by the flow rate adjusting valve 35 is the first electrode chamber 40A generated when the electrolyzed water is generated and oxygen gas and the first electrode via the diaphragm 43. It is desirable to set the flow rate corresponding to the sum of ions moving from the chamber 40A to the second electrode chamber 40B. In this case, only the oxygen gas generated in the first electrode chamber 40A by the electrolysis of water flows out from the first electrode chamber 40A. Thereby, while the utilization efficiency of water is improved further, the structure for discharging | emitting electrolytic acid water from the refrigerator 1 becomes unnecessary.

  The water discharge unit 50 includes water discharge pipes 51a and 51b, a flow path switching valve 52, a water discharge pipe 53, and an exhaust pipe (exhaust means) 54. The water discharge pipe 51a communicates with the first electrode chamber 40A, and the water discharge pipe 51b communicates with the second electrode chamber 40B. The flow path switching valve 52 is driven by, for example, a motor, and switches the connection between the flow paths in the water discharge section 50, that is, the water discharge pipes 51 a and 51 b, the water discharge pipe 53, and the exhaust pipe 54.

  In the state shown in FIG. 4, the water discharge pipe 51 a is connected to the exhaust pipe 54, and the water discharge pipe 51 b is connected to the water discharge pipe 53. The water discharge pipe 53 extends, for example, to the water discharge unit 25 at the front of the hydrogen dissolving apparatus 20 and is connected to the water discharge port 25a. On the other hand, the exhaust pipe 54 extends, for example, to the upper part of the hydrogen dissolving apparatus 20 and is connected to the exhaust pipe (exhaust means) 26 through a joint 26a. As shown in FIG. 1, the exhaust pipe 26 penetrates the upper door portion 1 a upward while being sealed from the refrigerator compartment 10, and has an exhaust port 26 b at the upper end of the upper door portion 1 a. Thereby, oxygen gas generated in the electrolytic chamber on the anode side is discharged to the outside of the refrigerator 1 without being released into the refrigerator compartment 10, so that oxidation of food in the refrigerator compartment 10 can be suppressed.

  The water storage tank 19 shown in FIG. 1 supplies water to the ice making device 17 through the water supply channel 19b in addition to the hydrogen dissolving device 20 already described. That is, the water stored in the water storage tank 19 is shared by the generation of hydrogen water and the generation of ice. Therefore, the structure of the refrigerator 1 is simplified, and the food storage space in the refrigerator compartment 10 can be increased.

  Hydrogen water in which hydrogen is dissolved from the hydrogen melting device 20 may be automatically supplied to the ice making device 17. For example, by connecting a hydrogen water supply pipe branched from the water discharge pipe 53 to the ice making device 17, hydrogen water can be supplied from the hydrogen melting device 20 to the ice making device 17. According to such a configuration, ice in which hydrogen is dissolved can be automatically generated, and the convenience of the refrigerator 1 is further enhanced.

  As mentioned above, although the refrigerator 1 of this embodiment was demonstrated in detail, this invention is changed and implemented in various aspects, without being limited to said specific embodiment. That is, the refrigerator 1 includes at least a refrigerator compartment for storing food in a low temperature state, a water cooling means such as an evaporator 15 for cooling water, a hydrogen dissolving device 20 for dissolving hydrogen in water cooled by the water cooling means, As long as it has.

  The hydrogen dissolving apparatus 20 is not limited to a configuration in which hydrogen is dissolved in water by the electrolytic cell 40 shown in FIG.

  FIG. 5 shows a hydrogen dissolving apparatus 20 </ b> A that is a modification of the hydrogen dissolving apparatus 20. The hydrogen dissolving apparatus 20A is different from the hydrogen dissolving apparatus 20 in that a hydrogen dissolving tank 46 is provided in the hydrogen dissolving part 24A. Of the modified example shown in the figure, the configuration of the hydrogen dissolving apparatus 20 described above can be adopted for portions not described below.

  The hydrogen dissolving apparatus 20A includes a hydrogen dissolving tank 46, a pump 47, a hydrogen generating apparatus 60, and a hydrogen tank (hydrogen storage means) 61. The hydrogen dissolving tank 46 is supplied with water that has been stored in the water storage tank 19 and cooled. Hydrogen is dissolved in the water supplied from the water storage tank 19 inside the hydrogen dissolution tank 46. Hydrogen supply means including a hydrogen generator 60, a hydrogen tank 61 and a pump 47 is connected to the hydrogen dissolution tank 46.

  The hydrogen generator 60 generates hydrogen gas. As the hydrogen generator 60, for example, an electrolytic cell having the same form as the electrolytic cell 40 shown in FIG. 4 can be applied. In this case, by limiting the water supplied to the cathode chamber, hydrogen gas that has not been dissolved in the electrolyzed water in the water in the cathode chamber is discharged from the cathode chamber in a gaseous state and supplied to the hydrogen tank 61.

  Further, the hydrogen generator 60 may be a device that generates hydrogen gas by a chemical reaction. An example of such an apparatus is an apparatus that generates hydrogen gas by reacting water with magnesium. As water used for the electrolysis or chemical reaction in the hydrogen generator 60, water stored in the water storage tank 19 can be used.

  The hydrogen tank 61 stores the hydrogen gas generated by the hydrogen generator 60. Instead of the hydrogen tank 61, a hydrogen cylinder may be applied. By configuring the hydrogen cylinder to be replaceable, the hydrogen generator 60 may be discarded.

  The pump 47 is provided in the hydrogen dissolving part 24A. The pump 47 pumps the hydrogen gas stored in the hydrogen tank 61 to the hydrogen dissolution tank 46. As a result, high-pressure hydrogen gas is supplied to the hydrogen dissolution tank 46, and the hydrogen gas is dissolved in the water in the hydrogen dissolution tank 46 to generate hydrogen water.

  The hydrogen dissolution tank 46 is connected to the water outlet 25 a by a water discharge pipe 27. The hydrogen water generated in the hydrogen dissolution tank 46 is taken out from the water outlet 25 a through the water discharge pipe 27. The water discharge pipe 27 is provided with a water discharge valve 27a. When the water discharge valve 27a is opened, the hydrogen water generated in the hydrogen dissolution tank 46 flows through the water discharge pipe 27 and is taken out from the water discharge port 25a.

  FIG. 6 shows a hydrogen dissolving apparatus 20 </ b> B that is another modification of the hydrogen dissolving apparatus 20. The hydrogen dissolving apparatus 20B is different from the hydrogen dissolving apparatus 20A in that hydrogen gas is supplied to the water storage tank 19 to generate hydrogen water. Of the modified example shown in the figure, the configuration of the hydrogen dissolving apparatus 20A described above can be adopted for portions not described below.

  In the hydrogen dissolving apparatus 20 </ b> B, the pump 47 is connected to the water storage tank 19. For this reason, the hydrogen dissolving part 24B is comprised by the water storage tank 19, and the hydrogen dissolving tank 46 is abolished.

  The pump 47 pumps the hydrogen gas stored in the hydrogen tank 61 to the water storage tank 19. As a result, high-pressure hydrogen gas is supplied to the water storage tank 19, and the hydrogen gas is dissolved in the water in the water storage tank 19 to generate hydrogen water. The hydrogen water generated in the water storage tank 19 flows through the water supply channel 19a and the water discharge pipe 27 and is taken out from the water discharge port 25a.
