The cassette body 11K1 and its lid 11K2 may be configured such that the elastic claw of the lid 11K2 engages with the engaging portion of the cassette body 11K1, or the cassette body 11K1 and the lid 11K2 may be coupled by screws. .

  In a state where the cassette body 11K1 and the lid 11K2 are coupled, the upper surface of the sterilization element 17 comes into contact with the lid 11K2, and the front surface of the sterilization element 17 faces the front opening 11K4 formed on the front surface of the cassette body 11K1. . Since the water circumference (part that contacts water) is formed in the cassette 11K, the cassette body 11K1 does not become a water reservoir, and by removing the cassette 11K, all the water circumference part (part that contacts water) can be cleaned, In addition, repair and inspection of the electrode unit 14Y and cleaning / replacement of the sterilization unit 10 are facilitated.

  The cassette 11K has a handle portion 11K3 provided on the lid 11K2 in a state where the electrode unit 14Y and the sterilization element 17 are arranged between the cassette body 11K1 and the lid 11K2 which are open on the upper surface. It is a combination that can be attached to and detached from the cassette housing portion 10A. For this reason, the cassette 11K is detachably inserted into the housing body 11A through the window 11B1 of the lid 11B, and is set in the cassette housing portion 10A in the cassette 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, and the front opening 11K4 of the cassette body 11K1 is in communication with the blower outlet 24 so that the sterilization element 17 is connected to the blower outlet 24.

Provided. When the water storage tank 12 is inserted into a predetermined position of the tank chamber 13 and the water storage switch 38 is activated (for example, turned on), the control unit 50 is activated and the sterilization unit 10 is operable (for example, the blower 20 and When the water storage tank 12 is pulled out of the tank chamber 13 and the water storage switch 38 is operated (for example, turned off), the sterilization unit 10 is in the operation stop state (for example, the blower 20). And the energization stop state to the electrode unit 14Y).

  The electrode unit 14Y is supported on the side wall of the electrolysis chamber 15 with the electrode 14 for electrolysis and the water level detection electrode 141 supported by the electrode housing 14A. Specifically, a pair of plus (+) and minus (−) electrolysis electrodes 14 are interposed between the synthetic resin electrode housing members 14A1 and 14A2 on the left and right sides via an intermediate synthetic resin electrode housing member 14A3. The water level detection electrode 141 of the electrolysis chamber 15 is paired with one electrode of the electrolysis electrode 14 and is held in an electrically separated state. The electrode unit 14Y includes a connector 142 to which a lead wire for supplying power to the electrode 14 for electrolysis and the water level detection electrode 141 is connected. The connector 142 is held in the mounting hole 143 of the synthetic resin member 14A1. It is a configuration. The water level in the electrolysis chamber 15 is detected by detecting the water level in the electrolysis chamber 15 when the water level detection electrode 141 forms a plus (+) and minus (−) pair with one electrode of the electrolysis electrode 14. When the water level in the electrolysis chamber 15 falls below a predetermined water level, a water supply LED 40K described later is lit to notify that the water storage tank 12 has become empty.

  The cassette 11K is inserted and set in the housing main body 11A through the window 11B1 of the lid 11B, so that the lower end of the connector 142 on the electrode unit 14Y side is connected to the connector (142A in FIG. 10) provided on the housing main body 11A. In addition, the connector 142 is detached from the connector 142A provided on the housing main body 11A by removing the cassette 11K from the housing main body 11A.

  The housing 11 constituted by the housing main body 11A and the lid 11B and the cassette 11K constituted by the cassette main body 11K1 and the lid 11K2 are made of synthetic resin. In the housing main body 11 </ b> A, an electric circuit board 37 including the circuit elements of the control unit 50 is accommodated in a horizontal state in a room partitioned by a partition wall behind the blower chamber 19. The electric circuit board 37 is electrically connected to the electrode unit 14Y, the blower 20, and the water storage switch 38.

  The suction filter 21 positively removes oil components in the air as well as the dust in the air, considering that the storage 1, that is, the place where the refrigerator-freezer 1 is installed is mostly a kitchen. It has a function to adhere. The suction filter 21 is inserted into a predetermined position of the filter chamber 22 in a horizontal state from the filter insertion port 25, is supported at an intermediate position of the height of the peripheral wall 11C, and is kept floating from the bottom surface of the filter chamber 22. The shape protrudes forward from the filter insertion opening 25. The suction filter 21 has a configuration in which a sheet-like filter element 21E is held by a lattice-shaped pressing plate 21H2 on a lattice portion 21H1 of a filter holder 21H made of synthetic resin. A shape in which the front end portion of the filter holder 21H, which is the front portion of the filter 21, protrudes forward from the filter insertion port 25 in a state where the suction filter 21 is stored in a predetermined position in the filter chamber 22 in a horizontal state from the filter insertion port 25. It is. The protruding front end portion forms a knob handle portion 21A. A decorative plate 21A1 is attached to the front surface of the handle portion 21A. The air suction port 26 is covered with a suction cover 26A whose outer surface uses an air suction passage between narrow bars.

  In the horizontal state in which the suction filter 21 is inserted, the forced air generated by the operation of the blower 20 is sucked in the air around the refrigerator-freezer 1 from the air suction port 26, and this air is indicated by an arrow W in FIG. 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 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.

  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.

  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 state, the letters “filter” are written in correspondence with the LED 40F for prompting the replacement of the suction filter 21, and the letters “automatic” are written in correspondence with the LED 40G for automatic operation. "Force (1H)" is written. In addition, the characters “mode / power” are written corresponding to the power switch 43. Further, as shown in FIG. 4, the characters “switch SW” are written corresponding to the operation control changeover switch 35, and the characters “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.
