A magnet-filled gasket 42 that is adsorbed to the periphery of the front opening of the refrigerator-freezer body 2 is provided on the periphery of the back surface of the front doors 7, 8, 9.

  The sterilization unit 10 is suitable for sterilizing the storage 1, that is, the ambient air in which the refrigerator-freezer 1 is installed. The sterilization unit 10 includes a housing 11 serving as a body, and the housing 11 is combined with the housing body 11A having an upper surface opening surrounded by a peripheral wall 11C and the housing body 11A so as to close the upper surface opening of the housing body 11A. It is comprised with the lid | cover 11B. The housing 11 has a flat shape having a predetermined thickness, that is, a flat shape, and a tank on which the water storage tank 12 is placed on the left and right sides (left side in the figure) of the housing body 11A. A chamber 13 is formed, and an electrolysis chamber 15 (electrolysis unit) in which an electrode 14 for generating electrolyzed water containing hypochlorous acid is disposed in the central portion, and a sterilizing element communicating with the electrolysis chamber 15 through an electrolyzed water passage 16A 17 is formed, and a blower chamber 19 in which the blower 20 is placed is formed, and a filter chamber 22 in which the suction filter 21 is placed in a horizontal state is formed on the other left and right sides (right side in the drawing). . Further, a tank insertion port 23 is formed on the front wall of the peripheral wall 11C corresponding to the tank chamber 13, an air outlet 24 is formed corresponding to the sterilization element 17, and a filter insertion port corresponding to the suction filter 21. 25 is formed. An air suction port 26 is formed on the side wall of the peripheral wall 11 </ b> C corresponding to the side surface of the filter chamber 22. If the air suction port 26 is formed in the lid 11B on the upper surface, there is a risk that the air suction port 26 may be blocked if something is placed on the lid 11B.

  The water storage tank 12 is provided with an open / close valve 27 that is spring-biased in a direction to be always closed at the bottom of the tip portion inserted into the tank chamber 13. The water storage tank 12 has a water inlet on its upper surface, and this water inlet is hermetically closed by an openable / closable sealing cap 12B. In the tank chamber 13, a water storage portion 13 </ b> A that is recessed below the bottom of the water storage tank 12 is formed. A projection 28 is provided that protrudes upward from the bottom of the water storage portion 13A. 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. Enters the water reservoir 13A and is kept at a constant water level. This constant water level is maintained by the balance between the water pressure of the sealed water storage tank 12 and the air pressure applied to the water surface of the water storage portion 13A. The water storage tank 12 has a flat rectangular shape with a low height (thin thickness) that fits within the height of the surrounding wall 11C when inserted in the tank chamber 13, and is inserted into a predetermined position of the tank chamber 13. In this state, the shape protrudes forward from the tank insertion port 23. This protruding front part is a knob part 12A.

  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. In the suction filter 21, in the inserted horizontal state, air sucked from the air suction port 26 passes from the upper surface to the lower surface of the suction filter 21 and is sucked into the blower chamber 19 from the rear portion of the filter chamber 22. The blower 20 has a sirocco fan configuration that is rotated by an electric motor, and the forced air sent from the blower 20 is sent to the sterilization element 17 from the air passage 29 that spreads left and right toward the sterilization element 17 located in front of the blower 20. Is done. The height of the blower 20 is a height that fits within the height of the surrounding wall 11C.

  The disinfecting element 17 has a structure in which a sucking element part 17B that forms a plurality of parallel horizontal air passages 17A between the sucking element parts 17B is attached to an element case 17C, and the lower part of the disinfecting element 17 is water. The horizontal air passage 17 </ b> A is directed in the front-rear direction in a state where it is immersed in the electrolyzed water of the receiving portion 18. 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 in the blower 20 passes from the air passage 29 through the air passage 17A of the sterilizing element 17. In this case, the sterilized element 17 is sterilized by touching the electrolyzed water sucked up by the sterilizing element 17, and the sterilized air is sent forward from the blower outlet 24. The height of the sterilization element 17 is a height that fits within the height of the surrounding wall 11C.

  The tap water collected in the water storage section 13A of the tank chamber 13 is supplied to the electrolysis chamber 15 from the narrow water passage 16B on the side wall of the water storage section 13A. In the electrolysis chamber 15, plus (+) and minus (−) electrodes 14 are disposed, and water in the electrolysis chamber 15 is electrolyzed by energization of the electrodes 14, and electrolysis containing hypochlorous acid. Produce water. 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 electrode 14 is supported by the electrode housing 14 </ b> A and supported by the electrolytic chamber 15 on the side wall. Water in the water storage tank 12 enters the water storage portion 13A from the opening / closing valve 27, enters the electrolysis chamber 15 through the thin (narrow) water passage 16B, and enters the electrolysis chamber 15 from the electrolysis chamber 15 through the thin (narrow) water passage 16A. The amount of water that evaporates by contact with air while being supplied to the water 18 can effectively use the water in the water storage tank 12. For this reason, the surface area in which 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, but in order to suppress the evaporation of water in the water passages 16A and 16B connecting them, It is a thin (narrow) water passage 16A.

  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 lid 11B is formed with a window 36 for taking in and out the sterilizing element 17, and the sterilizing element 17 can be taken out and attached by grasping a handle 17D provided on the upper surface of the sterilizing element 17. Since the upper part of the sterilizing element 17 is fitted to the window 36 almost completely, there is almost no possibility that the air is leaked from here.

  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. A suction filter 21 is provided in the housing 11 in a planar arrangement, and a tank insertion port 23 into which the water storage tank 12 is detachably inserted from the front of the housing 11 and a suction filter 21 are detachably inserted from the front of the housing 11. And a ventilation outlet 24 through which the forced air passing through the air passage 17A of the sterilization element 17 blows forward. On the upper surface of the sterilization unit 10, a window 36 for inserting and removing the sterilization element 17 is provided. Is formed.

  The sterilization unit 10 can be installed and used alone in a suitable place such as a kitchen, but in the kitchen, generally, the upper surface of the refrigerator-freezer main body 2 having a height of about 1800 mm is not used and remains as it is. Since there are many cases, it is preferable to use the upper surface of the refrigerator-freezer main body 2 effectively. The configuration in that case will be described below. The upper surface of the refrigerator-freezer main body 2 is substantially flat, and the sterilization unit 10 is attached to the upper surface of the refrigerator-freezer main body 2 in a state where the water storage tank 12, the front end of the suction filter 21 and the air outlet 24 face the front. A decorative panel 30 is provided at the front of the top surface of the refrigerator-freezer main body 2 so as to extend substantially across the width of the refrigerator-freezer main body 2, and the sterilization unit 10 is disposed on the rear side of the decorative panel 30. The decorative panel 30 is formed with an air outlet 31 having a rear end substantially matching the width of the air outlet 24 and having left and right side walls that are curved or straight from the rear toward the front toward the front end. The air outlet 24 of the fungus unit 10 is attached to the rear end portion of the air outlet 31 of the decorative panel 30 in a communicating state.

  The decorative panel 30 is formed with a window 32 for taking in and out the suction filter 21 and a window 33 for taking in and out the water storage tank 12 on both sides of the air outlet 31. The knob portion 21 </ b> A faces, and the knob portion 12 </ b> A at the front of the water storage tank 12 faces in the window 33. If a small sterilization unit 10 of a size that can be applied to various storages 1 is prepared, and a decorative panel 30 that matches the width of the storage 1 for each type of storage 1 is facilitated, each type of storage 1 It is not necessary to manufacture the sterilization unit 10, and 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 switch 35 for controlling the operation of the sterilization unit 10 can be provided in the sterilization unit 10, but when the decorative panel 30 is installed, this switch is provided on the front surface of the decorative panel 30 for ease of operation. 35 is provided. When the switch 35 is turned on, the electrode 14 and the blower 20 are energized, and when the switch 35 is turned off, the electrode 14 and the blower 20 are de-energized. The electrode 14 and the blower 20 are energized for a predetermined time (eg, 30 minutes), the energization of the electrode 14 and the blower 20 is cut off for a predetermined time (eg, 4 hours), and the electrode 14 and the blower 20 are again turned off for a predetermined time (eg, 30 minutes). The operation of repeating the relationship of cutting off the power supply to the electrode 14 and the blower 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).

  Since the free chlorine concentration contained in tap water varies depending on the region where the sterilization unit 10 is used, if the free chlorine concentration is high, the sterilization unit 10 has a constant operation time in any region. There is a case where the odor of chlorine delivered from the fungus unit 10 is bothered and 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. If it is low, the switch 35 can be provided with a switch for changing 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, so that the operation time of the sterilization unit 10 is lengthened.

  Therefore, as the switch 35, a strong operation switch 35A, a medium operation switch 35B, and a weak operation switch 35C are provided. When the free chlorine concentration is low (this is a standard state), the strong operation switch 35A is turned on. Based on the timer of the control unit, the electrode 14 and the blower 20 are energized for a predetermined time (for example, 30 minutes), the energization to the electrode 14 and the blower 20 is cut off for a predetermined time (for example, 4 hours), and again for a predetermined time (for example, 30 minutes) The electrode 14 and the blower 20 are energized, and the operation of repeating the relationship of cutting off the energization of the electrode 14 and the blower 20 for a predetermined time (for example, 4 hours) is performed. In order to stop the operation of the sterilization unit 10, the strong operation switch 35A may be turned off. If the strong operation switch 35A is a push-push type, the control unit controls the operation stop so that the operation mode is set when the strong operation switch 35A is turned on for the first time and the stop mode is set when the strong operation switch 35A is turned on for the second time. You can also

  Further, when the free chlorine concentration is medium, the controller 14 timer energizes the electrode 14 and the blower 20 for a predetermined time (for example, 20 minutes) based on the ON of the operation switch 35B, and for a predetermined time (for example, 4 hours). ) Relationship between cutting off the power supply to the electrode 14 and 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). Repeat the operation. When the operation of the sterilization unit 10 is stopped, the intermediate operation switch 35B may be turned off as described above.

  Further, when the free chlorine concentration is high, the electrode 14 and the blower 20 are energized for a predetermined time (for example, 10 minutes) by the timer of the control unit based on the ON of the weak operation switch 35C, and for a predetermined time (for example, 4). Time) The electrode 14 and the fan 20 are de-energized, the electrode 14 and the fan 20 are energized again for a predetermined time (for example, 10 minutes), and the electrode 14 and the fan 20 are de-energized for a predetermined time (for example, 4 hours). Perform an action that repeats the relationship. When the operation of the sterilization unit 10 is stopped, the weak operation switch 35B may be turned off as described above.

  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.

  The switch 35, the strong operation switch 35A, the medium operation switch 35B, and the weak operation switch 35C that control the operation of the sterilization unit 10 may be provided on the operation panel provided on the storage 1, that is, the front door of the refrigerator 1 or the like. Good.

  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 all of the water that receives the water supplied from the water storage tank 12 (the part that comes into contact with water) is formed in the cassette 11K, the cassette body 11K1 does not become a water reservoir, and by removing the cassette 11K, All downstream water-related portions (portions that come into contact with water) can be cleaned, and repair and inspection of the electrode unit 14Y taken out together with the cassette 11K 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 Correspondingly arranged. The water storage tank 12 can be inserted into the tank chamber 13 from the tank insertion port 23.

  The water storage tank 12 is composed of a tank main body 121 having an upper opening and a lid 122 that is welded to the tank main body 121 and completely closes the tank main body 121 in a watertight state, and is formed at the bottom near the front end that is inserted into the tank chamber 13. The water supply port 123 is provided with an opening / closing valve 27 that is spring-biased in a direction to be always closed. The on-off valve 27 is composed of the spring, the valve, and a plurality of parts to which these are attached, and is assembled to the water supply port 123. The tank body 121 and the lid 122 may be configured such that the elastic claw of the lid 122 engages with the locking portion of the tank body 121, or the tank body 121 and the lid 122 may be coupled by screws.

  The water storage unit 13A includes a protrusion 28 protruding upward from the bottom thereof, and when the water storage tank 12 into which tap water has been injected from the water injection port is inserted into a predetermined position of the tank chamber 13, the opening / closing valve 27 is pushed up by the protrusion 28. The water in the water storage tank 12 enters the water storage section 13A and is kept at a constant water level. This constant water level is maintained by the balance between the water pressure of the sealed water storage tank 12 and the air pressure applied to the water surface of the water storage portion 13A. The water storage tank 12 has a flat rectangular shape with a low height (thin thickness) that fits within the height of the surrounding wall 11C when inserted in the tank chamber 13, and is inserted into a predetermined position of the tank chamber 13. In this state, the front end portion projects forward from the tank insertion port 23. The protruding front end portion forms a knob handle portion 12A. A decorative plate 12A1 is attached to the front surface of the handle portion 12A.

  When the water storage tank 12 is inserted into a predetermined position of the tank chamber 13, the water storage switch 38 is operated by an operation lever 39 that is pushed by the side wall of the water storage tank 12 and is biased so as to move outward. 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 body 11A through the window 11B1 of the lid 11B, whereby the lower end of the connector 142 on the electrode unit 14Y side is connected to the connector 142A provided on the housing 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. 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.
