The blower 20 has a configuration in which a centrifugal fan that is rotated by an electric motor is housed in a fan case 20K having an air inlet at the center of the lower surface and a forced air outlet 20P at a part of the side surface. A sirocco fan is used as the centrifugal fan. Adopted. The forced air sent from the forced air outlet 20P of the blower 20 flows out from the opening 29A formed in the front wall of the blower chamber 19 and the rear wall of the cassette body 11K1 formed in communication with the forced air outlet 20P. It passes through the air passage 29 that spreads left and right toward the sterilization element 17 located in the front, is sent toward the sterilization element 17, passes through the air passage 17 </ b> A of the sterilization element 17, and forwards from the front air outlet 24. It is a mechanism that is sent to. The height of the blower 20 is a height that fits within the height of the surrounding wall 11C.

  The fan 20 has a configuration in which the entire fan case 20K is supported by a plurality of vibration isolating rubbers 20G in order to suppress noise caused by vibration during operation. Specifically, the lower surface of the fan case 20K of the blower 20 is placed on an anti-vibration rubber 20G supported on the bottom wall of the housing body 11A, and the upper surface of the fan case 20K of the blower 20 is placed on the lid 11B of the housing body 11A. The side surface of the blower 20 that is pressed by the supported vibration-proof rubber 20G is in a support state in which the protrusions 201 protruding outward from the fan case 20K of the blower 20 are sandwiched by the vibration-proof rubber 20G disposed on both sides thereof. . As a result, the blower 20 is not fixed with screws in the sterilization unit 10, but the surroundings are supported by the anti-vibration rubber 20G. Therefore, vibration during operation is attenuated by the anti-vibration rubber 20G and It becomes difficult to be transmitted to.

  The sterilization element 17 has a horizontally long rectangular shape configured to form a plurality of parallel horizontal air passages 17A between the suction element portions 17B, and the lower part of the sterilization element 17 is immersed in the electrolyzed water of the water receiving portion 18. The air passage 17A in the horizontal direction faces in the front-rear direction in the state of being disposed in the cassette body 11K1. For this reason, in the sterilizing element 17, the sucking element part 17B sucks up the electrolyzed water in the water receiving part 18 by capillary action, and the forced air generated by the blower 20 flows into the opening 29A formed in the rear wall of the cassette body 11K1. When passing through the air passage 17A of the sterilizing element 17 through the air passage 29, the sterilized air is sterilized by touching the electrolyzed water sucked up by the sterilizing element 17, and the sterilized air is forwarded from the air outlet 24. It is a mechanism that is sent to. The height of the sterilization element 17 is a height that fits within the height of the surrounding wall 11C.

  In order for the forced air from the blower 20 to pass through the sterilization element 17 effectively, the height of the front and rear walls of the water receiving portion 18 is low, and the front and rear surfaces and side surfaces of the sterilization element 17 are front and rear of the water receiving portion 18. It abuts against the walls and side walls. Since the side wall of the water receiving part 18 is higher than the height of the sterilization element 17, even if the sterilization element 17 is in contact, the electrolyzed water sucked up by the suction element part 17B does not spill from the side wall. When the front and rear surfaces of the sucking element portion 17B are in contact with the front and rear walls of the water receiving portion 18, the electrolytic water sucked by the sucking element portion 17B overflows the front and rear walls of the water receiving portion 18 and There is a possibility that the air flows into the air passage 29 and spills from the front air outlet 24. In order to prevent this, since the upper surface of the front wall of the water receiving portion 18 corresponds to the bottom wall of the front opening 11K4 of the cassette body 11K1, the upper surface of this front wall is higher on the air outlet 24 side and is directed toward the water receiving portion 18. The inclined surface 17P is lowered. In addition, the air passage 29 corresponding to the upper surface of the rear wall of the water receiving portion 18 is an inclined surface that is higher in the rear and lower toward the water receiving portion 18.

In the electrolysis chamber 15, a pair of plus (+) and minus (−) electrolysis electrodes 14 and a water level detection electrode 141 paired with one of the electrolysis electrodes 14 are disposed. When the electrode 14 is energized, the water in the electrolysis chamber 15 is electrolyzed to generate electrolyzed water containing hypochlorous acid. The electrolyzed water is supplied from the narrow electrolyzed water passage 16 </ b> A to the water receiver 18 and is sucked up by the sterilization element 17 by capillary action. The electrodes 14 and 141 are supported by the electrode housing 14A and supported by the electrolytic chamber 15 on the side walls as described above. Water in the water storage tank 12 enters the water storage section 13A from the open / close valve 27, enters the electrolysis chamber 15 through the water passage 16B, and is supplied from the electrolysis chamber 15 to the water receiving section 18 through the water passage 16A. In addition, the amount of water that evaporates when exposed to air is small, so that the water in the water storage tank 12 can be used effectively. For this reason, the surface area where the water in the water storage part 13A, the electrolysis chamber 15 and the water receiving part 18 is in contact with the air is made as small as possible.

  As described above, the water storage tank 12, the electrode 14, the sterilization element 17, the blower 20, and the suction filter 21 are assembled in the housing main body 11 </ b> A so as to be within the height of the peripheral wall 11 </ b> C, and are flat. The lid 11B is combined with the housing main body 11A, and both are coupled by screws or the like, and these are housed in the housing main body 11A. The cassette 11K grips the handle portion 11K3 provided on the lid 11K2, and is inserted into the housing main body 11A through the loading / unloading window 11B1 of the cassette 11K, and is set in the cassette storage portion 10A in the cassette main body 11K1. In this set state, the water storage portion 13A is housed and disposed in a recess 13B formed at the bottom of the tank chamber 13, the sterilization element 17 is disposed corresponding to the air outlet 24, and the water storage tank 12 is placed in the tank chamber 13 from the tank insertion port 23. Insertion becomes possible. Further, in this set state, the upper portion of the cassette 11K, that is, the lid 11K2 fits almost completely into the window 11B1, so there is almost no possibility that the air blown from the blower 20 leaks from the window 11B1.

  As described above, the sterilization unit 10 includes the tank chamber 13 which is a water storage tank mounting portion, the electrolysis chamber 15, the sterilization element 17 of the water receiving portion 18, the blower 20 of the blower chamber 19, and the filter chamber 22.

The protective panel 30B3 is provided on the upper wall (air outlet door) 30B of the decorative panel 30 so as to close the front side of the sterilizing element 17 in an open state.

  The upper wall of the blower outlet 31 corresponding to the upper wall of the decorative panel 30 constitutes a blower outlet door 30B that can be rotated upward when the water storage tank 21 and the suction filter 21 are inserted and removed. As a specific configuration, the decorative panel 30 forms an air outlet 31 between the board 30A attached to the upper surface of the refrigerator-freezer main body 2 with screws and the upper surface of the board 30A located above the board 30A. And an air outlet door 30B that is rotatably coupled to the substrate 30A.

  The substrate 30A constitutes the lower wall of the decorative panel 30. The blower outlet 31 is formed in a long shape on the left and right between the blower outlet door 30B as the upper wall and the substrate 30A as the lower wall. In addition, the decorative panel 30 is designed to be unified with the refrigerator-freezer 1 in a front view by setting the length over the width of the refrigerator-freezer body 2. For this reason, the left and right portions of the decorative panel 30 cover the attachment substrate portion HJP of the hinge device HJ that is screwed to the upper surface of the refrigerator-freezer body 2. The front door of the refrigerator-freezer 1 shown in the figure is the left and right doors 7A, 7B, and the position adjustment of the doors 7A, 7B with respect to the refrigerator-freezer main body 2 is performed by loosening screws and adjusting the attachment position of the upper hinge device HJ. The left and right portions of the decorative panel 30 are configured with removable covers 30C and 30C. The covers 30C and 30C are disposed on the left and right sides of the blower outlet door 30B and attached to the upper side of the substrate 30A.

  As shown in FIGS. 2 and 5 to 12, the decorative panel 30 is fixed to the upper surface of the refrigerator-freezer main body 2 and covers the upper surface of the front door of the refrigerator-freezer 1 so as to cover the upper surface of the refrigerator-freezer 1. It projects in a bowl shape to the front until it is almost flush with the front shape of the. The front doors of the refrigerator-freezer 1 shown in the figure are the left and right doors 7A and 7B. The front surfaces of the front and rear doors have a convex curved surface shape extending over the left and right doors 7A and 7B. And extends forward from the refrigerator-freezer main body 2 so as to cover the upper surfaces of the left and right doors 7A and 7B. For this reason, the board | substrate 30A has projected in the hook shape ahead to the front-surface shape of the front door of the refrigerator-freezer 1 in a substantially flush state.

  The board 30A is attached between the lower plate 30A1 having a hinge corresponding part 30A2 that covers the hinge device HJ disposed on the left and right sides of the upper surface of the refrigerator refrigerator body 2, and the left and right hinge corresponding parts 30A2 on both the left and right sides. The upper plate 30A3 that forms the lower side surface is used. Further, the blower outlet door 30B includes a lower plate 30B1 that forms the upper surface of the blower outlet 31, and an upper plate 30B2 that covers the lower plate 30B1, and is formed to project from the left and right rear ends of the upper plate 30B2. 30B21 is axially supported by the rotation support portion 30A11 formed on the lower plate 30A1 of the substrate 30A, so that the air outlet door 30B is attached to the substrate 30A as shown in FIGS. 2, 8, 10, and 12. On the other hand, as shown in FIGS. 5 to 7, 9, and 11, the air outlet door 30 </ b> B can be rotated to a state in which the air outlet door 30 </ b> B is opened upward with respect to the substrate 30 </ b> A.

  In order for the purified air delivered from the blower outlet 24 of the sterilization unit 10 to be sent widely to the left and right, the blower outlet 31 of the decorative panel 30 communicates with the blower outlet 24 at its rear end, The side wall has a shape spreading from the rear to the front. The left and right side walls of the air outlet 31 are formed by a knob handle portion 21A at the projecting front end of the suction filter 21 and a knob handle portion 12A at the front portion of the water storage tank 20, so that the water storage tank 20 and the suction filter 21 are regular. In the state where the handle portion 21A and the handle portion 12A are housed in the decorative panel 30, the surfaces of the handle portion 21A and the handle portion 12A on the air outlet 31 side are as shown in the figure. Furthermore, it has a shape that inclines in a streamlined manner from the rear to the front.

  Stopper portions 30B11 that are recessed upward are formed on the left and right sides of the lower plate 30B1 of the air outlet door 30B. When the air outlet door 30B is closed substantially horizontally to the substrate 30A, a passage for the air outlet 31 is formed between the substrate 30A and the air outlet door 30B, and the handle portion of the water storage tank 12 is provided in the stopper portion 30B11. Since the top end of 12A and the top end of the handle 21A of the suction filter 21 are in contact with each other, the air outlet door 30B prevents the water storage tank 12 and the suction filter 21 from moving forward and dropping off due to vibration or the like. At the same time, the left and right side walls of the air outlet 31 are formed by the handle portion 12A and the handle portion 21A, respectively. Therefore, the stopper portion 30B11 is formed in a shape corresponding to the shape of the handle portion 12A and the handle portion 21A, respectively.

  In the state where the blower outlet door 30B is opened, a protective action portion 30B3 which closes the front side of the sterilization element 17 is formed in a state extending rearward at the central portion of the blower outlet door 30B. The protective action portion 30B3 is configured by protective action portions 30B31 and 30B32 extending rearward at the center portions of the lower plate 30B1 and the upper plate 30B2. As shown in FIG. 5 to FIG. 7 and FIG. 11, by opening the air outlet door 30B so that the water storage tank 12 and the suction filter 21 can be pulled out forward, that is, in the figure, the air outlet door 30B is opened. When the protective action part 30B3 rotates so as to close the back side of the air outlet 31 in front of the air outlet 24 in a state of being opened approximately 45 degrees or more, when the hand is inserted into the air outlet 31 from the front, It is prevented that the hand touches the sterilization element 17 wet with water.

  As a result, the sterilization element 17 can be prevented from being damaged by touching the hand with the sterilization element 17, and the electrolysis electrode 14 and the water level detection electrode 141 of the electrode unit 14Y are energized. In the unlikely event of an electric shock caused by touching the fungus element 17, it is possible to prevent such an accident.

  Further, with the air outlet door 30B opened until the handle portion 12A and the handle portion 21A are detached from the stopper portion 30B11, the handle portion 12A and the handle portion 21A are held, respectively, and the water storage tank 12 and the suction filter 21 are put in and out. It becomes possible from. In this case, since the substrate 30A projects in a bowl shape to the front and substantially flush with the front shape of the front door of the refrigerator / freezer 1 so as to cover the upper surface of the front door of the refrigerator / freezer 1, Using the upper surface of the substrate 30A forming the wall as a guide surface, the water storage tank 12 and the suction filter 21 can be taken in and out, and this can be easily taken in and out.

  A hinge corresponding portion 30A2 that covers the hinge device HJ is formed on the left and right sides of the lower plate 30A1 of the substrate 30A. The hinge corresponding portion 30A2 has a screw HJ1 that fixes the hinge device HJ to the upper surface of the refrigerator-freezer main body 2. The exposed hole 30A21 is formed to cover the mounting substrate portion HJP of the hinge device HJ. The covers 30C and 30C are elastically engaged with screws 30C1 screwed into the lower plate 30A1 and locking portions of the lower plate 30A1 so as to cover the hinge corresponding portions 30A2 formed on the left and right sides of the lower plate 30A1 of the substrate 30A. It is detachably attached by the engaging claw. For this reason, the covers 30C and 30C are removed by loosening the screws 30C1 and removing the engaging claws from the locking portion. In this state, the hinge mounting screws HJ1 are loosened to adjust the fixing position of the hinge device HJ. The attachment position of the doors 7A and 7B can be adjusted.

  By providing the decorative panel 30 as described above, a decorative effect on the front side of the sterilization unit 10 including the cover of the hinge device HJ can be obtained. Moreover, if the small sterilization unit 10 of the magnitude | size applicable to various storages 1 is prepared and the decorative panel 30 matched with the left-right width of the storage 1 for every kind of the storage 1 will be facilitated, the kind of the storage 1 It is not necessary to manufacture the sterilization unit 10 every time, and it can be applied to various storages 1 only by replacing the decorative panel 30, and the cost of the sterilization unit 10 can be suppressed.

  The control unit 50 of the sterilization unit 10 includes, in addition to the electric circuit board 37, an operation control switch of the sterilization unit 10, a control circuit 46 operated by the operation control switch, and a display unit 40 for displaying this operation state. . The operation control switch includes an operation control changeover switch 35 that controls the operation state of the sterilization unit 10, a power switch 43 of the sterilization unit 10, and a reset switch 44. The control circuit 46 includes covers 30C and 30C. It is stored in one side. The display unit 40 includes a water supply LED 40K, a display LED 40E that prompts replacement of the sterilization element 17, a display LED 40F that prompts replacement of the suction filter 21, a display LED 40G for automatic operation, and a display of weak operation status. LED 40H is provided. The power switch 43 is disposed on the cover 30C so as to be operable from the front surface of the right cover 30C in front view, and the display unit 40 is disposed so as to be visible from the front surface of the right cover 30C in front view.

  As shown in FIG. 3, the display unit 40 writes “water supply” in correspondence with the water supply LED 40K, and writes “element” in correspondence with the display LED 40E that prompts replacement of the sterilization element 17. Corresponding to the LED 40F for indicating the weak operation, corresponding to the LED 40F for indicating that the filter 21 is displayed in response to the LED 40F for prompting the replacement of the suction filter 21 "Force (1H)" is written. Further, the characters “mode / power” are written in correspondence with the power switch 43. In addition, as shown in FIG. 4, the letters “switch SW” are written corresponding to the operation control changeover switch 35, and the letters “reset SW” are written corresponding to the reset switch 44.

  Moreover, in the state fixed to the upper surface of the refrigerator-freezer main body 2 as mentioned above, the decorative panel 30 projects in a bowl shape so as to be close to the upper surface of the front door of the refrigerator-freezer 1 and cover the upper surface of the front door. Yes. In consideration of the appearance design, the overhanging length of the bowl-shaped portion of the decorative panel 30 is shaped like a bowl that is substantially flush with the front shape of the front door of the refrigerator-freezer 1, and the operation control is performed. The changeover switch 35 and the reset switch 44 correspond to the upper surface of the closed door 7B on the right side when viewed from the front so that the changeover switch 35 and the reset switch 44 are disposed corresponding to the protruding portion in the bowl shape. It is arranged in the cover 30C so as to be operable from the lower side through the hole or notch of 30A1.

  For this reason, the operation control changeover switch 35 and the reset switch 44, which are specific switches, cannot be operated when the door 7B is closed, and can be operated from below to above when the door 7B is open. This stabilizes the operation of the operation control changeover switch 35 and the reset switch 44 which are specific switches. Such a saddle-like projecting configuration of the decorative panel 30 and the arrangement of the specific switch can be similarly adopted in the refrigerator-freezer 1 of the first embodiment. The power switch 43 is turned on by illuminating the push button of the power switch 43 with an LED housed therein.

  A circuit board 46A provided with a control circuit 46 supported by the front and rear holders 45A and 45B on the back side is supported in the right cover 30C, and the water supply LED 40K and the disinfection element 17 are exchanged on the circuit board 46A.

  The connection between the circuit board 46A and the electric circuit board 37 or the electric circuit on the refrigerator 1 side is made by connecting the connector 47A on the circuit board 46A side to the connector 47A connected to the electric circuit board 37 on the sterilization unit 10 side, This is done by connecting the connector 47C on the refrigerator 1 side. Therefore, when the sterilization unit 10 is attached to or detached from the refrigerator-freezer main body 2 or when the right cover 30C is removed for adjustment of the hinge device HJ, the work can be performed by attaching / detaching these connectors. It becomes easy to do. The combined connectors 47A, 47B, and 47C are housed in the right cover 30C, so that they are not exposed to the outside and dust hardly adheres to them.

  Since the free chlorine concentration contained in tap water or the like varies depending on the region where the sterilization unit 10 is used, if the operation time of the sterilization unit 10 is constant, if the free chlorine concentration is high, from the sterilization unit 10 You may be worried about the odor of chlorine sent out and you may feel uncomfortable. For this reason, when the free chlorine concentration is high and low, the operation time of the sterilization unit 10 can be varied. When the free chlorine concentration is high, the operation time of the sterilization unit 10 is shortened, and the free chlorine concentration is reduced. When it is low, the operation time of the sterilization unit 10, that is, the operation time of the blower 20 or the energization time of the electrode 14 and the blower 20 is controlled by the switch 35 so that the operation time of the sterilization unit 10 is lengthened. .

  When the free chlorine concentration is high and low, the operation time of the sterilization unit 10 can be varied. When the free chlorine concentration is high, the operation time of the sterilization unit 10 is shortened, and when the free chlorine concentration is low. The operation time of the sterilization unit 10, that is, the operation time of the blower 20, or the operation time of the electrode 14 and the blower 20 is varied by the operation control switch 35 so that the operation time of the sterilization unit 10 is lengthened. .

  The operation control changeover switch 35 has a changeover switch configuration that switches between strong, medium, and weak operation states. When the concentration of free chlorine is low with the power switch 43 turned on (this is the standard state), the operation control changeover switch 35 is switched to the strong (automatic) position to perform strong operation (automatic operation). The display LED 40G is turned on.

  At the time of shipment of the refrigerator-freezer 1, the operation control changeover switch 35 is set to a strong operation position in which the automatic operation mode that is the standard operation state is set. In this setting, with the power switch 43 turned on, the timer of the control unit 50 energizes the electrode 14 and the blower 20 for a predetermined time (for example, 30 minutes) and to the electrode 14 and the blower 20 for a predetermined time (for example, 4 hours). The electrode 14 and the fan 20 are energized again for a predetermined time (for example, 30 minutes), and the operation of repeating the relationship of de-energizing the electrode 14 and the fan 20 for a predetermined time (for example, 4 hours) is performed. The operation of the sterilization unit 10 can be limited to a predetermined time. For example, when the integration time of energization to the electrode 14 and the blower 20 is 3 hours, the repeated operation may be controlled to stop. Thus, the sterilized air circulates in the storage 1, that is, the area (room) where the refrigerator 1 is installed, and purifies the air in this area (room). In order to stop the operation of the sterilization unit 10, the power switch 43 may be turned off.

  When the free chlorine concentration is high, the operation control changeover switch 35 is switched to a weak operation while the power switch 43 is turned on, so that the display LED 40H is turned on. When a predetermined time (for example, 1 hour) elapses due to the timer of the control unit 50, the weak operation is automatically switched to the strong operation of the standard operation. By this switching, the LED 40H is turned off and the LED 40G is turned on. Further, in a state where the operation control changeover switch 35 is set to a weak operation, the electrode 14 and the blower 20 are energized for a predetermined time (for example, 10 minutes) by the timer of the control unit 50, and the electrode 14 is set for a predetermined time (for example, 4 hours). The operation of repeating the relationship of turning off the power to the blower 20, turning on the electrode 14 and the blower 20 again for a predetermined time (for example, 10 minutes), and turning off the power to the electrode 14 and the blower 20 for a predetermined time (for example, 4 hours). And when the accumulated power supply time to the electrode 14 and the blower 20 reaches a predetermined time (for example, 1 hour), it may be automatically switched to the strong operation of the standard operation. In order to stop the operation of the sterilization unit 10, the power switch 43 may be turned off.

  If the free chlorine concentration is medium, the operation control changeover switch 35 is switched to the medium operation while the power switch 43 is turned on, and the display LED 40H is turned on. When a predetermined time (for example, 1 hour) elapses due to the timer of the control unit 50 during this middle operation, the operation is automatically switched to the strong operation of the standard operation. By this switching, the LED 40H is turned off and the LED 40G is turned on. Further, in a state where the operation control changeover switch 35 is set to the middle operation, the electrode 14 and the blower 20 are energized for a predetermined time (for example, 20 minutes) by the timer of the control unit 50, and the electrode 14 for a predetermined time (for example, 4 hours). The operation of repeating the relationship of cutting off the power supply to the blower 20, turning on the electrode 14 and the blower 20 again for a predetermined time (for example, 20 minutes), and turning off the power supply to the electrode 14 and the blower 20 for a predetermined time (for example, 4 hours). And when the accumulated power supply time to the electrode 14 and the blower 20 reaches a predetermined time (for example, 1 hour), it may be automatically switched to the strong operation of the standard operation. In order to stop the operation of the sterilization unit 10, the power switch 43 may be turned off.

  The operation can be switched between the weak operation and the strong operation (automatic operation mode) as described above also by operating the power switch 43. That is, the power switch 43 has a push-type switch configuration. When the first push is turned on, the power is turned on to enter the strong operation mode (automatic operation mode), and the LED 40G and the LED of the power switch 43 are lit. Then, the second operation turns on the strong operation mode (automatic operation mode) to the weak operation mode, the LED 40G is turned off, and the LED 40H is turned on. Then, when the third operation is turned on, the weak operation mode is terminated and the power is turned off, and the LEDs 40H and the power switch 43 are turned off.

  In the sealed 6 tatami room, if the capacity of the blower 20 is such that the operation time of the blower 20 is approximately 3 hours and the air in the sealed 6 tatami room can be circulated in its entirety, this 6 The disinfection effect of the tatami room can be configured to achieve approximately 99%, and can be applied as a miniaturized disinfection unit 10 that can be normally used.

  In addition, a switch that detects that a person has approached the sterilization unit 10 is provided, and the sterilization unit 10 is activated by such a switch (the electrode 14 and the blower 20 are energized), and the strong operation as described above is performed. The standard operation mode can be set.

  In addition, a 24-hour timer is provided in the control unit 50 of the sterilization unit 10, and the sterilization unit 10 is operated by the 24-hour timer for a predetermined time in the standard operation mode of the strong operation as described above, for example, at night. (Control in which energization is intermittently performed to the electrode 14 and the blower 20) may be performed so that the sterilization of air in an area (room) such as a kitchen is finished in the morning.

  In the above, when the water storage tank 12 is inserted into a predetermined position of the tank chamber 13 and the water storage switch 38 is turned on, the LED 40K is turned on, and the control unit 50 is activated to enable the sterilization unit 10 to operate. By turning on the switch 43, the blower 20 and the electrode unit 14Y are energized. When the water storage tank 12 is pulled out of the tank chamber 13 for water supply or the like, the water storage switch 38 is turned off and the LED 40K is turned on, and the controller 50 is activated to stop energization of the blower 20 and the electrode unit 14Y. Then, when the water storage tank 12 is inserted again into the predetermined position and the water storage switch 38 is turned on, the sterilization unit 10 becomes operable as described above. When the water storage tank 12 is pulled out and the water storage switch 38 is turned off, the power supply is turned off by the operation of the control unit 50. When the water storage tank 12 is inserted again at a predetermined position and the water storage switch 38 is turned on, the power supply is turned off. You may comprise so that the air blower 20 and the electrode unit 14Y may be in an energized state by turning ON the switch 43.

  In the above description, when the power switch 43 is turned on, the LEDs 40E and 40F are lit, so that they can be turned off by turning on the reset switch 44.

  The sterilization unit 10 displays the replacement time of the sterilization element 17. That is, when the power switch 43 is turned on to operate the sterilization unit 10 for the first time, the power supply is turned on for a certain period (for example, 1 year and 6 months) or to operate the sterilization unit 10 for the first time. In order to notify that the time to replace the sterilization element 17 has arrived when the accumulated time of the operation time of the sterilization unit 10 has reached a certain period (for example, 1 year and 6 months) after the switch 43 is turned on. The LED 40E is turned on by the operation of the control unit 50. The LED 40E can be turned off by turning on the reset switch 44 with the sterilization element 17 replaced.

  Further, the sterilization unit 10 displays the replacement time of the suction filter 21. That is, when the power switch 43 is turned on to operate the sterilization unit 10 for the first time, a certain period (for example, one month) has elapsed, or the power switch 43 is used to operate the sterilization unit 10 for the first time. In order to notify that the replacement time of the suction filter 21 has arrived when the accumulated time of the operation time of the sterilization unit 10 has reached a certain period (for example, a time of one month) since turning ON The LED 40F is turned on by the operation of 50. The LED 40F can be turned off by turning on the reset switch 44 with the suction filter 21 replaced.

As described above, the sterilization unit 10 has the handle portion 12A and the handle portion 21A, respectively, with the blower outlet door 30B open, and allows the water storage tank 12 and the suction filter 21 to be taken in and out from the front. The storage tank 12 and the suction filter 21 are put in and out of the tank chamber 13 and the filter chamber 22 by sliding.

  The present invention is particularly characterized in the configuration in which the water storage tank 12 is slid in and out of the tank chamber 13 and the relationship with the open / close valve 27. Hereinafter, this configuration will be described. Rib-shaped protrusions 12T that protrude downward from the left and right side portions of the water storage tank 12 and extend in the front-rear direction are provided at the left and right side portions of the opening / closing valve 27 so as to slide on the substantially flat bottom surface 131 of the tank chamber 13. . In consideration of the stable sliding of the water storage tank 12 along the bottom surface 131 of the tank chamber 13 and the ease of inserting the water storage tank 12 into the sterilization unit 10 on the top surface of the refrigerator-freezer 1, In the ridge 12T, the right and left rear ridges 12T1 and the left and right front ridges 12T2 are integrally formed in the water storage tank 12.

  As described above, when the water storage tank 12 is inserted into a predetermined position of the tank chamber 13, the opening / closing valve 27 is pushed up and opened by the projection 28, and the water in the water storage tank 12 enters the water storage section 13A and is kept at a constant water level. It is a configuration. For this reason, left and right side portions of the bottom surface 131 of the tank chamber 13 are provided with drop portions 132 into which the left and right rear protrusions 12T1 and the left and right front protrusions 12T2 fall. In the sagging portion 132, a sagging portion 132G in which the left and right rear ridge 12T1 falls is formed in a left and right depression, and a depression portion 132H in which the left and right front ridge 12T2 falls is formed in a left and right depression.

  The left and right rear ridges 12T1 form an inclined surface 12T11 whose end on the water tank insertion port 23 side (front side) is inclined in the insertion direction (rear) of the water tank 12 from the upper part to the lower part. The left and right front ridges 12T2 form an inclined surface 12T21 whose end on the water storage tank insertion port 23 side (front side) is inclined in the insertion direction (rear) of the water storage tank 12 from the top to the bottom. .

  In order to reduce the vertical thickness of the water storage tank 12 including the open / close valve 27, the open / close valve 27 is configured to be accommodated in the water storage tank 12. This configuration will be described. At the water supply port 123 formed at the bottom near the tip of the water storage tank 12 (closer to the insertion destination side), an annular mounting portion 124 is provided with an internal thread 124 </ b> A for mounting the opening / closing valve 27 on the inner surface.

  The on-off valve 27, which is a feature of the present invention, is shown as an exploded perspective view in FIGS. In this case, a movable valve 272 urged downward by a coil spring 273 held by a spring holder 274 so as to close the water supply passage 27 </ b> A is housed in the valve housing 271. The valve housing 271 is formed in an annular shape integrally projecting from a substrate portion 271A in which a plurality of water supply paths 27A constituting a liquid flow path are circularly arranged at substantially equal angular intervals, and opens and closes the circularly arranged water supply path 27A. 272 is supported by the substrate portion 271A. That is, the operating part 272A integrated with the movable valve 272 extends downward through the hole 271AK in the center of the substrate part 271A inside the circular water supply passage 27A, and the operating part 272A is connected to the substrate part 271A. The movable valve 272 is supported by the substrate portion 271A so as to be movable up and down. A male screw 271 </ b> B that engages with the female screw 124 </ b> A of the attachment portion 124 is formed on the outer peripheral portion of the valve housing 271.

  An annular flange 271A1 that is in close contact with the lower surface of the bottom wall 12B of the water storage tank 12 is formed on the outer periphery of the substrate portion 271A by screwing the male screw 271B and the female screw 124A. The close contact between the bottom wall 12B of the water storage tank 12 and the annular flange 271A1 is achieved by an annular seal packing 275 interposed therebetween.

  The spring holder 274 has a gate shape that covers the movable valve 272 from above. The upper side 274U and the left and right sides 274L and 274R hanging from the left and right ends of the upper side 274U are integrally formed of synthetic resin, and the left and right sides 274L and 274R are formed. An outwardly engaging portion 274A is formed at the lower end portion. The locking portions 274A of the left and right sides 274L and 274R are locked to the lower side of a holding piece 276 that protrudes inwardly on the upper side of a water passage hole 279 described later formed in the valve housing 271, thereby the spring holder 274 is It is in a state of being attached in the valve housing 271. In addition, the movable valve 272 is fitted in such a relationship that a locking portion 272B formed on the outer peripheral edge thereof moves up and down in the guide grooves 274B formed in the left and right sides 274L and 274R of the spring holder 274. The upper side 274U of the spring holder 274 supports the upper end of the spring 273, the lower end of the spring 273 is supported by the movable valve 272, and the movable valve 272 is biased by the spring 273 so as to close the water supply path 27A.

  In this state, as shown in FIGS. 30 and 34, the movable valve 272, the spring 273, and the spring holder 274 are housed in a valve housing 271 that is erected inward of the water storage tank 12. The water supply channel 27A is closed.

  Since the left and right width of the locking portion 274A is sufficiently shorter than the left and right width of the water passage hole 279, the locking portion 274A does not block the water passage hole 279. The locking portion 274A may be formed on the inner surface of the valve housing 271 at a position away from the water passage hole 279.

  As described above, the spring holder 274 has a gate shape in which the upper side 274U and the left and right sides 274L and 274R hanging from the left and right ends thereof are formed, and the left and right sides 274L and 274R are located on both sides (90 The phase difference portion) is a shape in which a spatial region SP in which no drooping side exists is formed. With this configuration, the upper end of the spring 273 is supported by the upper side 274U of the spring holder 274, and the lower end of the spring 273 is supported by the movable valve 272, whereby the movable valve 272 closes the water supply path 27A by the spring force of the spring 273. Thus, the state is biased downward.

  The open / close valve 27 has a combination configuration shown in FIGS. 30 to 35 in such a relationship. In the combination opening / closing valve 27 shown in FIGS. 30 to 35, water supply (replenishment) of water into the water storage tank 12 is carried out from the water supply port 123 into the water storage tank 12 with the opening / closing valve 27 removed from the female screw 124A. Tap water can be supplied (supplemented). After this water supply (replenishment), the open / close valve 27 is screwed onto the female screw 124A. That is, as shown in FIG. 30 to FIG. 35, the board is attached to the mounting recess 12 </ b> B <b> 1 formed on the bottom wall 12 </ b> B of the water storage tank 12 through the annular seal packing 275 by screwing the male screw 271 </ b> B and the female screw 124 </ b> A. The annular flange 271A1 of the portion 271A is in close contact with the bottom wall 12B, and the opening / closing valve 27 is attached to the water supply port 123 formed in the bottom wall 12B of the water storage tank 12.

  In order to ensure that the movable valve 272 closes the water supply passage 27A, a disc-shaped seal packing 277 is attached to the lower side of the movable valve 272, and the substrate is disposed so that the seal packing 277 surrounds the water supply passage 27A. The circular protrusions formed on the upper surface of the portion 271A are in close contact with each other.

  As described above, when the water storage tank 12 is inserted into the tank chamber 13, the left and right rear ridges 12T1 fall into the drop portion 132G, and the left and right front ridges 12T2 fall into the drop portion 132H. The tank 12 is held at a predetermined position in the tank chamber 13. In this state, as shown in FIGS. 32 and 35, the opening / closing valve 27 is opened. In other words, the movable valve 272 is pushed up against the spring 273 by the protrusion 28 via the operating portion 272A, and the movable valve 272 opens the water supply path 27A.

  As shown in FIGS. 32 and 35, when the open / close valve 27 is opened, the water in the water storage tank 12 must be supplied to the lower water storage section 13B through the water supply path 27A. For this reason, a water passage hole communicating with the valve housing 271 attached to the water storage tank 12 is formed in the outer peripheral portion of the valve housing 271 and the attachment portion 124 by screwing the male screw 271B and the female screw 124A. . Specifically, a plurality of water passage holes 278 and 279 are formed through the lower portion of the female screw 124A of the attachment portion 124 and the lower portion of the male screw 271B of the valve housing 271. Particularly, by providing the water passage holes 278 and 279 so as to pass through the portions of the female screw 124A and the male screw 271B, the water passage holes 278 and 279 are located within the coupling range of the water storage tank 12 and the open / close valve 27. Thus, the height of the coupling range between the water storage tank 12 and the open / close valve 27 can be reduced as compared with the case where it is provided in a portion other than the portions of the female screw 124A and the male screw 271B.

  The pitch of the water passage holes 278 (substantially equal angular intervals) and the pitch of the water passage holes 279 (substantially uniform angular intervals) are arranged at a pitch at which the water passage holes 278 and 279 communicate with each other in at least one place. . In the embodiment, the pitch of the water holes 278 (substantially equal angular intervals) and the pitch of the water holes 279 (substantially equal angular intervals) are different pitches, and five water holes 278 are arranged at a pitch of 72 degrees. The four water holes 279 are arranged at a pitch of 120 degrees, and as a result, as shown in FIG. 36, the water holes 278 and 279 communicate with each other at least at one place. As described above, when the opening / closing valve 27 is attached to the water storage tank 12, one of the water holes 278 and 279 is connected so that the water holes 278 and 279 communicate with each other at least at one place. What is necessary is just to set it as the structure which has arrange | positioned the water hole by odd number as an even number, and arrange | positioned the other water passage hole as an even number.

  In order to prevent the opening / closing valve 27 from being opened while the water storage tank 12 is being taken in and out of the tank chamber 13, the operating portion 272A of the movable valve 272 is prevented from being pushed up. For this reason, on the bottom surface of the water storage tank 12, an annular protective wall 280 having a longer protruding length than the operating portion 272A is integrally formed around the operating portion 272A. Accordingly, the protruding length of the operating portion 272A downward from the bottom surface of the water storage tank 12 is slightly shorter than the protruding length of the protective wall 280 downward from the bottom surface of the water storage tank 12, and is shown in FIG. 31 and FIG. Thus, there is a slight difference S1 between the two, and when the water storage tank 12 is taken into and out of the tank chamber 13, the lower end of the protective wall 280 is placed in the tank before the lower end of the operating portion 272A contacts the bottom surface 131 of the tank chamber 13. Since it contacts the bottom surface 131 of the chamber 13, the movable valve 272 does not open the water supply passage 27A. The protective wall 280 has a six-surface appearance so as to be a gripping part for removing and opening the opening / closing valve 27 when supplying tap water to the water storage tank 12 as described above. Yes.

  Further, as described above, since the opening / closing valve 27 is disposed at a position closer to the insertion destination side (front end side) in the water storage tank 12, the protective wall 280 is also disposed corresponding thereto. In this state, the left and right rear ridges 12T1 extend to the insertion destination side (front end side) of the water storage tank 12 across both the left and right sides of the protective wall 280, and the protruding length of the protective wall 280 downward from the bottom surface of the water storage tank 12 In addition, the protruding length from the bottom surface of the water storage tank 12 of the right and left rear ridges 12T1 corresponding thereto is slightly longer. For this reason, as shown in FIGS. 31 and 34, a slight difference S2 occurs between the two, and the lower end of the protective wall 280 contacts the bottom surface 131 of the tank chamber 13 when the water storage tank 12 is taken in and out of the tank chamber 13. Since the lower ends of the left and right rear protrusions 12T1 are in contact with the bottom surface 131 of the tank chamber 13 before, the protective wall 280 does not get in the way and the water storage tank 12 does not become difficult to put in and out of the tank chamber 13.

  In such a configuration, a case where the water storage tank 12 is slid in and out of the tank chamber 13 with the sterilization unit 10 attached to the upper surface of the refrigerator 1 will be described. As described above, with the air outlet door 30B opened to the state where the handle portion 12A is detached from the stopper portion 30B11, the right and left rear ridges of the water storage tank 12 are held with the handle portion 12A as shown in FIG. 12T1 is placed on the upper surface of the substrate 30A, and the water storage tank 12 faces the tank insertion port 23.

  From this state, as shown in FIG. 38, with the handle 12A held and the water storage tank 12 lifted in a substantially horizontal state, the left and right rear ridges 12T1 are used as the upper surface of the substrate 30A with the upper surface of the substrate 30A as a guide surface. The water storage tank 12 is inserted into the tank chamber 13 while sliding. By this insertion, the left and right rear ridges 12T1 slide on the bottom surface 131 of the tank chamber 13, and then the left and right front ridges 12T2 slide on the bottom surface 131 of the tank chamber 13, so that the water storage tank 12 is in a substantially horizontal state. It reaches the back side of the tank chamber 13. In this case, the operating portion 272A comes into contact with the bottom surface 131 of the tank chamber 13 in accordance with the above-described relationship between the protrusions 12T1 on the left and right rear portions, the protective wall 280, and the protruding length of the operating portion 272A from the bottom surface of the water storage tank 12. The water storage tank 12 can be inserted into the tank chamber 13 smoothly with the protrusions 12 </ b> T <b> 1 at the left and right rear portions.

  As shown in FIG. 39, when the water storage tank 12 reaches the back side of the tank chamber 13 by this insertion, the inclined surface 281 toward the lower back side formed at the front end of the water storage tank 12 at the back upper part of the tank chamber 13. Proximity to. In this state, the inclined surface 12T11 of the right and left rear ridge 12T1 contacts the front end of the falling portion 132G, and the inclined surface 12T21 of the left and right front ridge 12T2 contacts the front end of the falling portion 132H and puts water. Due to the weight of the water storage tank 12, the left and right rear ridges 12T1 fall into the drop portion 132G and the left and right front ridges 12T2 fall into the drop portion 132H. Then, in a state where the water storage tank 12 is housed in a predetermined position of the tank chamber 13, that is, in a final lowered state, as shown in FIG. 40, the protective wall 280 and the operating portion 272A fall into the water storing portion 13A, and the operating portion 272A Since it abuts against the protrusion 28 and is pushed up against the spring 273, the movable valve 272 is pushed up accordingly, and the water supply passage 27A is opened. Thus, the water in the water storage tank 12 enters the valve housing 271 through the communication portion of the water passage hole 278 and the water passage hole 279, and is supplied from there to the water storage portion 13A through the water supply passage 27A. Keep the water level.

  Further, in this final depressed state, the upper part on the insertion destination side (front end side) of the water storage tank 12 sinks into the recess 282 formed on the lower side of the inclined surface 281, so that vibration due to the operation of the refrigerator / freezer 1 and opening / closing of the door As a result, the water storage tank 12 is prevented from jumping up due to vibration and the like, and the state of the on-off valve 27 can be stably maintained.

  When the water storage tank 12 is pulled out from the tank chamber 13, the inclined surface 12T11 of the left and right rear ridge 12T1 comes into contact with the front end of the falling portion 132G, and the left and right front ridge 12T2 After the inclined surface 12T21 is in contact with the front end of the sagging portion 132H, the upper part of the insertion destination side (front end side) of the water storage tank 12 is released from the recess 282, and the water storage tank 12 rises and reaches the state of FIG. The water storage tank 12 can be pulled out from the tank chamber 13. Also in the case of this drawer, the protruding lengths of the right and left rear ridges 12T1, the protective wall 280, and the operating portion 272A from the bottom surface of the water storage tank 12 are such that the operating portion 272A has the bottom surface 131 of the tank chamber 13. The water storage tank 12 can be smoothly inserted into the tank chamber 13 without touching the left and right rear ridges 12T1.

  Further, instead of forming the inclined surface 12T11 on the left and right rear ridges 12T1, the front end of the falling portion 132G is an inclined surface, and instead of forming the inclined surface 12T21 on the left and right front ridges 12T2, the falling portion 132H. The same operation as described above can be obtained even with a configuration in which the front end of each is an inclined surface. Further, if an inclined surface 12T12 opposite to the inclined surface 12T11 is formed on the insertion destination side of the left and right rear ridges 12T1, the left and right rear ridges 12T1 of the water storage tank 12 are placed on the upper surface of the substrate 30A as shown in FIG. Even when the left and right rear protrusions 12T1 collide with the front end portion of the substrate 30A, the collision resistance is reduced by the inclined surface 12T12, and the water storage tank is caused by the mutual slide between the front end portion of the substrate 30A and the inclined surface 12T12. 12 can be easily inserted into the state shown in FIG.

  Further, if the inclined surface 12T22 opposite to the inclined surface 12T21 is formed on the insertion destination side of the right and left front protrusions 12T2, the right and left front protrusions are formed when the state shown in FIG. 38 is reached. Even if 12T2 collides with the front end portion of the substrate 30A, the collision resistance is reduced by the inclined surface 12T22, and the water storage tank 12 is inserted into the inner side of the tank chamber 13 by mutual sliding between the front end portion of the substrate 30A and the inclined surface 12T22. It becomes easy to do.

  As described above, the water storage tank 12 is a type in which the movable valve 272 rises and opens when the open / close valve 27 is lowered by insertion and the operating portion 272A is pushed up by the projection 28, so that the water storage tank 12 When the design is such that the vertical dimension of the tank chamber 13 into which the valve is inserted is reduced so as to reduce the size, the rising stroke of the movable valve 272 cannot be increased.

  With the open / close valve 27 open as described above, the water in the water storage tank 12 enters the valve housing 271 through the communicating portion of the water passage holes 278 and 279, and from there through the water supply passage 27A. To 13A. Further, when the diameter of the hole 271AK and the operating portion 272A in the central portion of the substrate portion 271A increases as it goes upward as in the embodiment, the operating portion 272A is pushed up by being brought into contact with the protrusion 28 and opened and closed. Since a gap is generated between the hole 271AK in the center of the base plate portion 271A and the operating portion 272A in a state where the valve 27 is opened, water in the valve housing 271 is slightly supplied to the water storage portion 13A also from this gap. .

  As described above, when the water storage tank 12 is inserted and dropped and the opening / closing valve 27 is opened to supply water to the water storage section 13A, the air accumulated in the water storage section 13A is transferred from the water storage tank 12 to the water storage section 13A. If it does not escape with water supply, this water supply will not be performed smoothly, but this air will escape into the upper valve housing 271 through the water supply path 27A located above the water storage part 13A. In the configuration of the embodiment, the valve housing 271 also escapes from a gap between the hole 271AK and the operating portion 272A. Thus, the passage through which the water in the water storage tank 12 is supplied to the water storage section 13A and the passage from which the air in the water storage section 13A escapes are the same.

  Thus, the air escaping into the valve housing 271 moves upward from the periphery of the movable valve 272 in the valve housing 271, escapes upward in the water storage tank 12 through the coil spring 273 and the spring holder 274. However, as described above, in the type in which the opening / closing valve 27 is opened by the insertion and dropping of the water storage tank 12, if the upward stroke of the movable valve 272 cannot be made large, the air escape path in the valve housing 271 becomes narrow, Becomes difficult to escape.

  In particular, the escape path is blocked by the spring holder 274 present in the valve housing 271, so that it is difficult to escape upward in the water storage tank 12. Therefore, in order to make this air escape smoothly, the open / close valve 27 of the present invention has the spring holder 274 attached with the upper side 274U that supports the spring 273, which is a necessary part, and the spring holder 274 as described above. The left and right sides 274L and 274R are left, and the gate regions are formed in the left and right sides 274L and 274R and the 90 ° portion with a space region SP that is largely open.

  As a result, even if the rising stroke of the movable valve 272 is not large, the air moving from the communicating portion of the water holes 278 and 279 quickly escapes upward from the left and right space regions SP without accumulating in the spring holder 274, The flow of water from the communicating part of the water holes 278 and 279 to the water supply path 27A is smoothly performed. Accordingly, when the water storage tank 12 is depressed, the movable valve 272 rises and the open / close valve 27 is opened.

  The water supply path 27A is configured by a plurality of holes arranged in an unbalanced manner so that the number on one side and the number on the other side are different from the axis GP passing through the centers of the left and right sides 274L and 274R of the spring holder 274. The supply of water to the water storage unit 13A and the escape of air from the water storage unit 13A can be performed smoothly.

  In the embodiment, as shown in FIG. 27, the water supply channel 27A is formed by three holes arranged at substantially equal angular intervals, and the axis GP passing through the centers of the left and right sides 274L and 274R of the spring holder 274 includes One 27A (b) is located on one side, the other two 27A (b) and 27A (c) are located on the other side, 27A (b) is a large hole, 27A (b) And 27A (C) are small holes. As a result, the air in the water storage section 13A escapes upward mainly from the large hole 27A (A), and the water in the valve housing 271 is supplied to the water storage section 13A from the small holes 27A (B) and 27A (C). Air escape and water supply can be performed smoothly.
