The suction filter 21 passes from the upper surface to the lower surface, flows into the blower chamber 19 from the rear portion of the filter chamber 22, and is sucked into the blower 20. The blower 20 has an air inlet in the center of the lower surface of the fan case 20K, and a centrifugal fan that is rotated by an electric motor is housed in a fan case 20K having a forced air outlet 20P in a part of the side surface of the fan case 20K. A sirocco fan is housed in the fan case 20K as the centrifugal fan. The blower 20 is disposed in the blower chamber 19 so that the forced air outlet 20P corresponds to the opening 29A formed in the front wall of the blower chamber 19 and the rear wall of the cassette body 11K1.

  In the state where the blower 20 is disposed in the blower chamber 19, the forced wind sent from the forced wind outlet 20P of the blower 20 is connected to the front wall of the blower chamber 19 and the rear wall of the cassette body 11K1 formed in communication with the blowout port 20P. The air flows out from the opening 29A formed in the air passage, passes through the air passage 29 extending toward the sterilization element 17 located in front of the blower 20, and is sent toward the sterilization element 17, and is sent to the sterilization element 17. It is a mechanism that passes through the passage 17A and is sent forward from the front air outlet 24. The height of the blower 20 is a height that fits within the height of the surrounding wall 11C.

  In particular, the present invention provides a configuration in which the fan 20 can be easily incorporated and supported, and noise can be suppressed by vibration of the fan 20. For this reason, the blower 20 has a configuration in which the entire fan case 20K is supported by a plurality of anti-vibration rubbers 20G. Specifically, as shown in an enlarged view in FIG. 9, the lower surface of the fan case 20 </ b> K of the blower 20 is supported by the peripheral portion of the air inlet formed on the bottom wall of the housing body 11 </ b> A that is the bottom wall of the housing 11. It is mounted on a vibration isolating rubber 20G attached to the portion 11A1 with a screw 20G1.

  With this attachment, the screw 20G1 passes through the anti-vibration rubber 20G and is screwed into the support portion 11A1 at a position lower than the upper surface of the anti-vibration rubber 20G so that its head is buried in the anti-vibration rubber 20G. Yes. For this reason, only the anti-vibration rubber 20G is in contact with the fan case 20K of the blower 20, and the screw 20G1 and the support portion 11A1 are not in contact. Further, the upper surface of the fan case 20K of the blower 20 is in contact with a vibration isolating rubber 20G attached to the support portion 11B1 formed on the lid 11B which is the upper wall of the housing 11 with screws 20G1. With this attachment, the screw 20G1 passes through the anti-vibration rubber 20G and is screwed to the support portion 11B1 at a position higher than the lower surface of the anti-vibration rubber 20G so that its head is buried in the anti-vibration rubber 20G. Yes. For this reason, only the anti-vibration rubber 20G is in contact with the fan case 20K of the blower 20, and the screw 20G1 and the support portion 11A1 are not in contact.

  Further, as shown in an enlarged view in FIG. 14, on the side surface of the blower 20, a pair of protruding protrusions 201 project outward from the fan case 20 </ b> K of the blower 20. It is the support state pinched | interposed by the anti-vibration rubber | gum 20G arrange | positioned. That is, the pair of protrusions 201 are disposed at positions that are approximately 180 degrees apart from each other so as to be positioned on one side and the other side of the side surface of the fan case 20K, and are disposed on the side surface of the fan case 20K of the blower 20. It is formed in the vertical direction. The pair of protrusions 201 are in contact with the side surfaces of the antivibration rubber 20G attached with screws 20G1 to the tips of a pair of columnar support portions 11A2 formed on the bottom wall of the housing body 11A. The anti-vibration rubber 20G is fixed by screwing the screw 20G1 onto the upper end of the support portion 11A2 in a state where the vibration-proof rubber 20G is put on the upper end of the support portion 11A2.

  The protrusions 201 of the pair of protrusions need not be specially provided, but may be those conventionally used for screw fixing the fan case 20K to the attachment part. In this case, the pair of protrusions 201 is used. Is a configuration in which a fixing screw hole for fixing the screw is formed in the distal end surface of the protrusion 201.

  For this reason, only the anti-vibration rubber 20G is in contact with the side surface of the fan case 20K of the blower 20, and the screw 20G1 and the support portion 11A2 are not in contact. Note that the columnar support portion 11A2 is formed on the lid 11B, and is in contact with the columnar support portion 11A2 formed on the lid 11B in contact with the side surface of the antivibration rubber 20G attached with the screw 20G1 as described above. It may be configured. In this manner, the pair of protrusions 201 is in a state of being sandwiched by the vibration isolating rubber 20G attached to the columnar support portions 11A2 on both sides.

  With this configuration, with the lid 11B attached to the upper surface of the housing main body 11A, the lower surface of the blower 20 is placed on the anti-vibration rubber 20G attached to the bottom wall of the housing main body 11A, and the upper surface of the blower 20 is The upper and lower surfaces of the blower 20 are supported by contacting the anti-vibration rubber 20G attached to the lid 11B of 11A. Further, since both sides of the pair of protrusions 201 provided on the side surface of the blower 20 are in a support state sandwiched between the vibration isolating rubber 20G attached to the housing main body 11A or the lid 11B, the blower 20 is laterally moved in the housing 11. Movement and rotation are prevented. In this supported state, the front end portion of the forced air outlet 20P formed on a part of the side surface of the fan case 20K of the blower 20 is a part of the housing 11 without any other vibration-proof rubber interposed in the housing 11. It is in a state of being opposed to each other through a gap (with a gap) between the opening 29A formed in the front wall of the blower chamber 19 and the rear wall of the cassette body 11K1. Thus, since the blower 20 is not fixed with screws in the sterilization unit 10, but the outer surface is supported by the anti-vibration rubber 20G, vibration during operation is attenuated by the anti-vibration rubber 20G. It becomes difficult to be transmitted to the surroundings.

  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.

  The tap water collected in the water storage section 13A of the tank chamber 13 is supplied to the electrolysis chamber 15 from the water passage 16B on the side wall of the water storage section 13A. 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 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.

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.

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.

  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 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.

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.
