  As shown in FIG. 4, a float 56 is provided in the water storage tank 33 so as to move up and down along the guide rod 57. The float 56 floats on the water W in the water storage tank 33 and moves up and down according to the water level in the water storage tank 33. A permanent magnet 58 is provided on the float 56. Two magnetic sensors 59 and 60 are provided vertically in the unit storage chamber 31 so as to be positioned in the vicinity of the float 56. By using these magnetic sensors 59 and 60 and the permanent magnet 58 of the float 56 and detecting the position of the permanent magnet 58 of the float 56 by the magnetic sensors 59 and 60, the presence or absence of water in the water storage tank 33 can be detected. .

  Specifically, when the upper magnetic sensor 59 detects the magnetic flux of the permanent magnet 58, it is detected that there is water in the water storage tank 33, and the lower magnetic sensor 60 detects the magnetic flux of the permanent magnet 58. Thus, it is detected that there is almost no water in the water storage tank 33. That is, the float 56, the permanent magnet 58, and the magnetic sensors 59 and 60 function as water detection means that can detect the presence or absence of water stored in the water storage tank 33.

  In the vegetable compartment 4, as shown in FIG. 7, a temperature sensor 61 is provided as temperature detecting means. The temperature sensor 61 is composed of a temperature measuring element such as a thermistor, for example, and detects the temperature of the vegetable compartment 4. The temperature sensor 61 is not limited to the above-described type, and may be another type.

  In the vegetable compartment 4, an upper container 63 and a lower container 64 disposed below the upper container 63 are provided. The upper container 63 is formed to have a length in the front-rear direction smaller than that of the lower container 64, and is disposed on the rear side of the lower container 64. A front end portion of the upper container 63 is positioned below the mist discharge port 42 of the base plate 27. In this state, when mist is discharged from the mist discharge port 42 into the vegetable compartment 4, the mist is supplied to both the lower container 64 and the upper container 63.

  As shown in FIG. 1, an operation panel 65 is provided on the front surface of the door 3 a of the refrigerator compartment 3. The operation panel 65 is provided with a mode changeover switch 66, other operation switches 67, and a display unit 68 (all of which are shown in FIG. 7). The mode changeover switch 66 is a switch for switching the operation mode (operation state) of the mist generator 26 to either a normal operation mode in which normal operation is performed or a stop mode in which operation is forcibly stopped. That is, the mode switch 66 constitutes a unit operation unit. The operation mode of the mist generating device 26 is switched by the user.

  The operation switch 67 is for inputting operations such as setting of the temperature in the cabinet, function setting of the small freezer compartment (switching between freezing and chilling), or switching of display on the display unit 68, for example. The display unit 68 displays various types of information such as the temperature in the cabinet and the temperature set value. That is, the mode switch 66, the operation switch 67, and the display unit 68 function as operation display means for inputting the settings of the entire refrigerator and displaying the operation state of the refrigerator.

  On the back of the refrigerator main body 1, a control device 70 (see FIG. 1) mainly including a microcomputer is provided. FIG. 7 is a block diagram showing an outline of an electrical configuration related to the gist of the present invention. The control device 70 is configured by a microcomputer including a CPU, a ROM, a RAM, and the like. A mode change switch 66, an operation switch 67, a display unit 68, a door switch 11, and a lid switch 50 provided on the operation panel 65 are provided. Various signals are input from the unit detection switch 49, the magnetic sensors 59 and 60, the temperature sensor 61, and the like. The control device 70 has a function of controlling the compressor 18, the refrigeration fan 13, the refrigeration fan 16, the automatic ice making device 10, the mist generating device 26, and the like based on these signals and a control program previously provided in the ROM or the like. I have.

  Further, the control device 70 includes a timer 71 as a time measuring means, and obtains the time taken from performing a certain process to performing the next process, the time elapsed from the previous process, or the current time. It is configured to be able to do. Furthermore, the control device 70 includes an EEPROM 72 as a non-volatile storage unit, and is configured to be able to store and read various data. The timer 71 may be a built-in timer 70 or a configuration using an external dedicated IC. Further, the storage means is not limited to the EEPROM 72, and another storage medium may be used.

Next, the operation of the above configuration will be described.
First, the basic operation of the mist generator 26 will be described. The operation mode is switched to the normal operation mode by the mode switch 66, and the atomization unit 28 is set at a normal position in the unit storage chamber 31 with the water W stored in the water storage tank 33. When a negative high voltage is applied to each mist discharge pin 39 of the mist generating device 26 in a state where the storage unit lid 30 is closed and the door of each storage chamber is closed, the mist discharge pin 39 is finely Mist is released.

  At this time, the mist discharged from each mist discharge pin 39 is supplied from the mist discharge port 42 into the upper container 63 and the lower container 64 of the vegetable compartment 4. The mist contains a hydroxy radical having a strong oxidizing action, and the mist containing the hydroxy radical is supplied into the upper container 63 and the lower container 64 of the vegetable chamber 4, thereby sterilizing and deodorizing the vegetable chamber 4. Is possible. In addition, the mist can maintain the freshness of food such as vegetables stored in the upper container 63 and the lower container 64.

  By the way, since the mist generating device 26 cannot generate mist when the water runs out, it is necessary to replenish water periodically in order to prevent idling. Furthermore, when the surface of the mist discharge pin 39 is continuously used, dirt such as slime adheres to it and clogging occurs, or dust in the cabinet adheres even when not in use. Since the mist discharge performance is lowered, it is preferable to clean the mist discharge pin 39 at a rate of about once a year, for example.

  In such a case, after the door 3a of the refrigerator compartment 3 is opened, the accommodating portion lid 30 of the front portion 7a of the partition plate 7 is slid rearward to fully open the opening 29 of the unit accommodating chamber 31. Then, the user inserts his / her hand into the unit accommodating chamber 31 to hold the atomizing unit 28 of the mist generating device 26, slides it forward, lifts it, and removes it from the unit accommodating chamber 31. Then, after removing the water storage tank 33 and replenishing water, the water storage tank 33 is attached to the atomization unit 28 again. At this time, the water storage tank 33 may be washed as necessary. When the door 3a is opened, the mist generator 26 automatically stops applying high voltage even in the normal operation mode, and temporarily stops the generation of mist.

  When cleaning the mist discharge pin 39, the upper case 34 is removed from the water storage tank 33, and the discharge portion cover 40 is removed from the upper case 34, and the mist discharge pin 39 is exposed for cleaning. When the replenishment and cleaning of the water are completed, the atomization unit 28 is assembled as before, and then the atomization unit 28 is accommodated in the unit accommodation chamber 31 and installed in a proper position. At this time, the feed pin 43 is inserted and connected to the connector 45. Thereafter, the housing lid 30 is slid forward to close the opening 29, and the door 3a of the refrigerator compartment 3 is closed. Thereby, the application of the high voltage to the mist generator 26 is resumed, and mist is generated.

  Thus, by providing the atomization unit 28 of the mist generator 26 so as to be detachable, maintenance of the mist generator 26 such as replenishment of water and cleaning of the mist discharge pin 39 can be performed.

  Next, with regard to the control contents of the control device 70 for the mist generating device 26, the main flow of processing (main processing) will be described first with reference to FIG. 8, and then the normal operation mode and The maintenance mode will be described in detail. In the following description, the expression “turning on the status LED 52 (or the maintenance LED 53)” represents “making the status LED 52 (or the maintenance LED 53) lit”. That is, in the present embodiment, the status LED 52 and the maintenance LED 53 are actually turned on only when the door 3a of the refrigerator compartment 3 is opened as will be described later. Expression is used.

  When the refrigerator is turned on, the control device 70 first determines whether or not the mist function setting is on in step A1, as shown in FIG. Here, the mist function setting is a setting as to whether or not the function of the mist generating device 26 is to be validated, and is valid when “on” and invalid when “off”. This mist function setting is set to off at the time of shipment. Therefore, when the user turns on the power for the first time after purchase, since the mist generation function is turned off (A1: NO), the process proceeds to step A8, and the shipment stop mode, that is, the status LED 52 and the maintenance LED 53 are turned off (extinguished). It will be in the state. At this time, the operation of the mist generator 26 is stopped.

  In this case, when the process of step A8 ends, the process proceeds to step A1 to determine again whether the mist generation function is on, and steps A1 and A8 are repeated until the mist function setting is turned on. That is, when the power is turned on for the first time after purchase, the processing related to the mist generating device 26 is not substantially performed until the mist function setting is turned on by the user, and a standby state is entered. When the mist function setting is turned on by the user in this standby state (A1: YES), the shipping mode is determined in step A2, the status LED 52 is turned on, and the maintenance LED 53 is turned on.

  When the mist function setting is turned on at the first power-on after purchase, it is considered that water is not yet stored in the water storage tank 33 of the mist generator 26. Therefore, when the mist function setting is turned on when the power is turned on for the first time, the control device 70 turns on the maintenance LED 53 to prompt the user to supply water. In this state, the mist generator 26 is still stopped.

  Subsequently, the control device 70 determines whether or not the mist function setting is on in step A3. If the mist function setting is off (A3: NO), the control device 70 proceeds to step A8 and enters the standby state described above. Become. That is, when the mist function setting is once turned on, but the mist function setting is turned off again, the status LED 52 and the maintenance LED 53 are turned off, and a standby state is entered.

  On the other hand, when the mist function setting is ON (A3: YES), the process proceeds to step A4, and it is determined whether or not the atomization unit 28 of the mist generating device 26 has been put in and out. When the power is turned on for the first time after purchasing the refrigerator, it is considered that there is no water in the water storage tank 33 of the mist generating device 26. Therefore, in order to operate the mist generating device 26, water is stored in the water storage tank 33. Need to be replenished. In order to supply water to the water storage tank 33, as described above, it is necessary to take out the atomization unit 28 once, supply water to the water storage tank 33, and then store the atomization unit 28 in the unit storage chamber 31 again. There is.

  Therefore, the control device 70 detects whether or not the door 3a of the refrigerator compartment 3 is opened by the door switch 11, and detects whether or not the opening 29 of the unit storage chamber 31 is opened by the lid switch 50, The detection switch 49 detects whether the atomizing unit 28 is accommodated in the unit accommodating chamber 31. And it detects that the atomization unit 28 was taken out based on the change (and the order which became the on / off state) of the on / off state of each of these switches (9, 50, 49). Further, after detecting that the atomizing unit 28 has been taken out, the atomizing unit 28 is again accommodated in the unit accommodating chamber 31 based on the change in the on / off state of each switch (49, 50, 9). Detect that.

  When it is determined in step A4 that the atomization unit 28 has not been taken in or out (A4: NO), the control device 70 waits until the atomization unit 28 is taken in and out after moving to step A2. . In this standby state, it is determined whether or not the mist function setting is turned on again in step A3 when the mist function setting is turned off during standby (validation of the mist generating device 26 is canceled). This is because the case is considered.

  On the other hand, if the control device 70 determines that the atomization unit 28 has been taken in and out (A4: YES), the control device 70 proceeds to step A5 and operates the mist generator 26 in the normal operation mode (details will be described later). . At this time, the control device 70 stores the number of times the power is turned on in the EEPROM 72 as the number of times the power is turned on.

  Now, as described above, it is desirable to periodically replenish and clean the mist generator 26 with water. Therefore, in step A6, the control device 70 determines whether or not a predetermined period has elapsed after shifting to the normal operation mode. In this case, the timer 71 measures the time elapsed since the transition to the normal operation mode. In this embodiment, one month is set as the predetermined period.

When one month has elapsed after shifting to the normal operation mode (A6: YES), the control device 70 shifts to step A7 and enters a maintenance mode (details will be described later). In this case, the maintenance performed is replenishment of water to the water storage tank 33. When maintenance is performed and the maintenance mode ends, the process proceeds to step A5, where the mist generator 26 is operated in the normal operation mode. Note that the elapsed time from the transition to the normal operation mode measured by the timer 71 is stored in the EEPROM 72 at a predetermined timing.
Thus, in the main process, the control device 70 confirms the state of the mist generating device 26 when the power is turned on, and repeatedly executes the normal operation mode and the maintenance mode.

Next, the process in the normal operation mode in step A5 will be described in detail with reference to FIG.
When the control device 70 shifts to the normal operation mode, in step B1, the status LED 52 is turned on, the maintenance LED 53 is turned off, and the operation of the mist generating device 26 is started. Since only the status LED 52 is lit in this state, the user can recognize that the mist generating device 26 is operating normally when the door 3a is opened. As will be described later, the status LED 52 is turned off when the door 3a is closed.

  Subsequently, the control device 70 determines whether or not the mist function setting is ON in step B2. When the mist function setting is on (B2: YES), the control device 70 determines whether or not the unit detection switch 49 is on in step B3. When the unit detection switch 49 is on (B3: YES), the atomization unit 28 is accommodated in the regular position of the unit accommodation chamber 31, and therefore the process proceeds to step B4 and the accumulated time is reached. After counting up, the process returns to the main process shown in FIG. The accumulated time is an elapsed time measured by the timer 71 from the time when the operation mode is shifted to the normal operation mode.

  On the other hand, if the unit detection switch 49 is off (B3: NO), the control device 70 determines that the unit is in the normal operation mode without the unit, turns on the status LED 52, turns on the maintenance LED 53, and Since there is no atomizing unit 28, the mist generating device 26 is stopped in order to prevent idling. Subsequently, when the mist function setting is ON in step B6 (B6: YES), the process proceeds to step B7 to determine whether or not the unit detection switch 49 is ON, and the unit detection switch 49 is OFF. If there is (B7: NO), the process proceeds to step B5 and waits until the unit detection switch 49 is turned on.

  When the unit detection switch 49 is turned on in this standby state (B7: YES), after resetting the integration time in step B8, the process proceeds to step B1 and the normal operation mode is repeated. In this case, since the atomization unit 28 is removed and accommodated again in the unit storage chamber 31, it is determined that maintenance such as replenishment of water and cleaning of the atomization unit 28 has been performed, and the accumulated time is reset. . If the mist function setting is off with the atomization unit 28 removed (B6: NO), the process proceeds to step B13 described later.

  In contrast, when the mist function setting is turned off by the user (B2: NO), the control device 70 determines that the unit is in the normal operation mode in step B9, turns off the status LED 52, The maintenance LED 53 is turned off, and the operation of the mist generator 26 is stopped.

  Subsequently, in step B10, it is determined whether or not the unit detection switch 49 is on. If it is on (B10: YES), the accumulated time is counted up in step B11. In this case, although the operation of the mist generating device 26 is stopped, the control device 70 leaves the atomizing unit 28 storing water since the atomizing unit 28 is accommodated in the unit accommodating chamber 31. To prevent this, the accumulated time is continuously counted up. In step B12, it is determined whether or not the mist function setting is on. If the mist function setting is not on (B12: NO), the process proceeds to step B9 and waits until the mist function setting is turned on. On the other hand, if the mist function setting is on (or turned on in the standby state) (B12: YES), the process returns.

  When the unit detection switch 49 is turned off in step B10 (B10: NO), the control device 70 proceeds to step B13 and executes the same unit-less normal operation mode processing as in step B5. Then, the process proceeds to step B14 to determine whether or not the mist function setting is on.

  If the mist function setting is off (B14: NO), the process proceeds to step B15 to determine whether or not the unit detection switch 49 is on. If it is off (B15: NO), the process goes to step B13. The process is repeated and the above processing is repeated. That is, when the user consciously turns off the mist function setting and the atomizing unit 28 is also removed, it is determined that the mist generating device 26 is not used, and the mist generating device 26 is used. Wait until your use resumes.

  On the other hand, when the mist function setting is on in step B14, more appropriately, when the mist function setting is turned on in the standby state where the mist generating device 26 is not used (B14: YES), the return is performed. To do. Alternatively, when the unit detection switch 49 is ON in step B15, that is, when the removed atomizing unit 28 is accommodated again in the unit accommodating chamber 31 (B15: YES), the accumulated time is calculated in step B16. After resetting, the process proceeds to step B9. When the user turns on the mist function setting in order to use the mist generating device 26 (B12: YES), the process returns. As a result, when the process proceeds to the next normal operation mode process, after checking for the presence or absence of water or the like, the mist generator 26 is operated in the normal operation mode if it is operable.

  As described above, in the normal operation mode, the control device 70 determines whether the mist function setting is on and whether the atomization unit 28 is accommodated in the unit accommodation chamber 31 or not. The operation of the maintenance LED 53 and the mist generator 26 is controlled. When the mist generator 26 is in a normally operable state, that is, when it is determined that the mist function setting is on and the atomization unit 28 is housed in the unit housing chamber 31, the status LED 52 is turned on, The mist generator 26 is operated.

Next, processing in the maintenance mode will be described in detail with reference to FIG.
When the control device 70 shifts to the maintenance mode, first, in step C1, the control device 70 determines that the unit is in the maintenance mode, turns on the status LED 52, and turns on the maintenance LED 53. In other words, at this point, the mist generator 26 is still in an operating state although it has shifted to the maintenance mode. Subsequently, in step C2, it is determined whether the mist function setting is on. If it is on (C2: YES), it is determined in step C3 whether the unit detection switch 49 is on.

  If the unit detection switch 49 is also on (C3: YES), the process proceeds to step C1. In this case, the control device 70 repeats steps C1 to C3 in order to notify the user that maintenance is necessary, and keeps the maintenance LED 53 on. Even if the operation mode is shifted to the maintenance mode, the operation of the mist generating device 26 does not always have an abnormality, so that the operation of the mist generating device 26 continues.

  Now, if the user takes out the atomizing unit 28 while the maintenance LED 53 is lit, the unit detection switch 49 is turned off (C3: NO), so that the process proceeds to step C4 to enter the maintenance mode without unit. The status LED 52 is turned on and the maintenance LED 53 is turned on. In this case, since the atomization unit 28 is not accommodated, the mist generator 26 is stopped. Subsequently, in step C5, it is determined whether or not the mist function setting is on. If it is on (C5: YES), the process proceeds to step C6 to determine whether or not the unit detection switch 49 is on. judge.

  If the unit detection switch 49 is not on (C6: NO), the control device 70 proceeds to step C4 and waits until the unit detection switch 49 is turned on. On the other hand, when the unit detection switch 49 is turned on (C6: YES), the integration time is reset in step C7, and the process returns. In this case, after shifting to the maintenance mode, the atomization unit 28 is once taken out and attached again to the unit accommodating chamber 31, so that it is determined that maintenance (water replenishment) has been performed, and the maintenance mode ends. That is, when the atomization unit 28 is taken in and out in the maintenance mode, the maintenance LED 53 is turned off.

  On the other hand, if the mist function setting is off in step C2 (C2: NO), the control device 70 proceeds to step C8, turns off the status LED 52, turns off the maintenance LED 53, and turns on the mist generating device. 26 is stopped. Subsequently, in step C9, it is determined whether or not the unit detection switch 49 is on. If it is on (C9: YES), the process proceeds to step C10 to determine whether or not the mist function setting is on. judge. At this time, if the mist function setting is OFF (C10: NO), the process proceeds to step C8 and enters a standby state.

  On the other hand, if the mist function setting is ON (C10: YES), the control device 70 proceeds to step C7, resets the accumulated time, and returns. In this case, since the mist function setting determined to be off in step C2 is determined to be on again in step C10, the user temporarily turns off the mist function setting and performs maintenance of the mist generating device 26. After that, it is considered that the mist function setting was turned on again. Therefore, the control device 70 determines that maintenance has been performed and returns.

  Now, in the state where the unit detection switch 49 is turned off in Step C9 (C9: NO), in Step C11, the same unit-less maintenance mode process as Step C8 is executed, and then in Step C12, the mist function is performed. It is determined whether the setting is on.

  In this case, if the mist function setting is off (C12: NO), the control device 70 proceeds to step C13 and determines whether or not the unit detection switch 49 is on. If it is off (C13 : NO), the process proceeds to Step C11 and is repeated. That is, when the user consciously turns off the mist function setting and the atomizing unit 28 is also removed, it is determined that the mist generating device 26 is not used, and the mist generating device 26 is used. Wait until your use resumes.

  On the other hand, when the mist function setting is turned on in step C12, more appropriately, when the mist function setting is turned on in the standby state where the mist generating device 26 is not used (C12: YES), After the accumulated time is reset in step C7, the process returns. Thus, when the process proceeds to the next normal operation mode process, the presence or absence of water is checked, and if it is operable, the mist generator 26 operates in the normal operation mode.

  Alternatively, when the unit detection switch 49 is on in step C13, that is, when the removed atomizing unit 28 is accommodated again in the unit accommodating chamber 31 (C13: YES), the process proceeds to step C8. It waits for the mist function setting to be turned on, and when the mist function setting is turned on (C10: YES), it returns via step C7.

  Thus, even in the maintenance mode, the control device 70 determines whether or not the status LED 52, based on whether or not the mist function setting is ON and whether or not the atomization unit 28 is accommodated in the unit accommodating chamber 31. The operation of the maintenance LED 53 and the mist generator 26 is controlled. When it is determined that the mist generator 26 has been maintained, the maintenance mode is terminated.

  Next, the timing when the status LED 52 and the maintenance LED 53 are actually turned on or off will be described together with the states of the door switch 11, the unit detection switch 49, and the lid switch 50 with reference to FIG. In the following description, it is assumed that the mist function setting is on.

  When the door 3a (R door) of the refrigerator compartment 3 is closed (D1: NO), even if the status LED 52 and the maintenance LED 53 are “on” in the normal operation mode or the maintenance mode described above, the step D2 Turns off at. That is, in this embodiment, since all are provided in the refrigerator compartment 3, in the state which the door 3a was closed, ie, the state which a user cannot visually recognize, it is light-extinguished irrespective of the operation mode. On the other hand, when the door 3a is opened (D1: YES), in step D3, it is determined whether the storage cover 30 is open, whether the atomization unit 28 is present (whether it is stored in the unit storage chamber 31). ) Changes the on / off state.

  Specifically, in a state where the housing cover 30 is open (D3: YES) and there is no atomization unit 28 (D4: YES), the status LED 52 is turned off and the maintenance LED 53 is turned on in step D5. . On the other hand, when the atomization unit 28 is present (D4: NO), the status LED 52 is turned off and the maintenance LED 53 is turned off in step D6. In other words, in a state where the housing cover 30 is open, the status LED 52 is turned off regardless of the presence or absence of the atomizing unit 28. That is, the container lid 30 is opened when the atomizing unit 28 is taken in and out. In this case, the user turns out that the energization to the atomizing unit 28 is stopped by turning off the status LED 52. Will be notified.

  On the other hand, when the container cover 30 is closed (D3: NO) and there is no atomization unit 28 (D7: YES), the status LED 52 is turned off and the maintenance LED 53 is turned on. Thereby, it is notified that the atomizing unit 28 is not present or that the atomizing unit 28 is not installed at the proper position, and the idling of the mist generator 26 is prevented.

  On the other hand, when the atomization unit 28 is present (D7: NO), the status LED 52 is turned on and the maintenance LED 53 is turned off. Thereby, it is notified that the mist generating device 26 is in a normally operable state.

According to the above-described embodiment, the following effects can be obtained.
Since the status LED 52 is provided, it is visually informed whether the mist generating device 26 is in an operable state, and the operating state of the mist generating device 26 can be easily confirmed. In addition, since the status LED 52 is provided in the refrigerator compartment 3 and lights up only when the door 3a is opened, it lights up when the door is closed (when the user cannot see the status indicator display). Without excessive power consumption can be reduced.

  Since the status LED 52 is turned off when the lid switch 50 is turned off (when the housing lid 30 is opened), the user can easily recognize that the mist generator 26 is stopped, The user can take out the atomization unit 28 with peace of mind.

Since the maintenance LED 53 is provided, it is possible to easily notify maintenance timing such as replenishment (or replacement) of water and cleaning of the water storage tank 33.
Since the maintenance LED 53 is provided in the refrigerator compartment 3 and is lit only when the door 3a is opened, excess power consumption can be reduced.

  An operation unit for switching the operating state of the mist generating device 26 is provided, and the status LED 52 is turned off when the mist generating device 26 is in a stopped state. Therefore, the operating state is confirmed like the mist generating device 26. Even a device that is difficult to detect can be easily notified that it is in a stopped state.

  Since the maintenance LED 53 is turned on when the atomizing unit 28 is not accommodated in the unit accommodating chamber 31, it is possible to prevent forgetting to install (forgetting to install) the atomizing unit 28 or an installation error.

  When the atomization unit 28 is taken in and out in the maintenance mode, the maintenance LED 53 is turned off in the subsequent processing, so that it is possible to easily grasp that the maintenance has been performed.

  When it is detected that the atomization unit 28 has been detached at least once after the power is turned on, the operation mode is shifted to the normal operation mode, so that the mist generator 26 is fed with no water in the water storage tank 33. Can be prevented.

  The timer 71 measures the integration period (the period during which the mist generator 26 has been used continuously), and the maintenance LED 53 is lit after a certain period of time, so that it is possible to notify the maintenance timing at an appropriate timing. it can. Thus, for example, in the case of the mist generator 26, maintenance such as periodic replenishment (or replacement) of water and cleaning of the water storage tank 33 for storing water is performed, so that a clean and sufficient amount of mist is always stored in the cabinet. It becomes possible to supply to.

  Since the EEPROM 72 is provided to store the number of times of power-on, it is possible to always notify maintenance such as water supply when the power is turned on for the first time. As a result, it is possible to prevent an idle operation in which the mist generator 26 is operated without water being supplied.

  Further, since the elapsed time measured by the timer 71 is stored in the EEPROM 72 which is a nonvolatile storage element, even if the power supply is temporarily cut off, the elapsed time after the maintenance is performed is continuously maintained. It is possible to calculate and to notify an appropriate maintenance time.

  Since the water storage tank 33 is provided in the atomization unit 28 and the atomization unit 28 is detachable from the unit storage chamber 31, water can be easily supplied to the water storage tank 33. Moreover, since the mist discharge | release pin 39 is also removable with the atomization unit 28, the mist discharge | release pin 39 can also be cleaned easily.

  Since the unit accommodating chamber 31 for accommodating the atomizing unit 28 is arranged in the front part 7a of the partition plate 7 located below the space where the door pocket 24 is accommodated, there is an obstacle when the accommodating portion lid 30 is opened and closed. The atomization unit 28 can be easily taken in and out.

  When the door switch 11 detects that the door 3a of the refrigerator compartment 3 is opened, the supply of power to the mist generating device 26 is cut off, so that the possibility that the user inadvertently touches the high voltage portion can be reduced. Therefore, the safety can be further improved.

  Since the shipment stop mode is provided, it is possible to prevent the maintenance LED 53 from being turned on in a situation where it is rare to actually put water, for example, when displaying at a store, and this is a function for customers (customers). Can be explained in an easy-to-understand manner.

  Since the status LED 52 is composed of a blue LED, a visually clean image can be given to the user when the mist generator 26 is operating. Further, since the maintenance LED 53 is constituted by a red LED which is a so-called warning color, the user's attention can be urged. Moreover, by using LED, it can suppress that temperature in a store | warehouse | chamber rises from there being little heat_generation | fever and can also power-out a power failure.

(Second and third embodiments)
Next, second and third embodiments of the present invention will be described. In the second and third embodiments, the operation at power-on is different from that of the first embodiment. In addition, since the structure of the refrigerator in 2nd and 3rd embodiment is substantially the same as 1st Embodiment, detailed description is abbreviate | omitted.

  In the first embodiment, as shown in FIG. 8, the mist function setting is turned on when the power is turned on, and the normal operation mode is entered on condition that the atomization unit 28 is taken in and out. In this case, for example, when the power supply is temporarily cut off due to a power failure or the like, the operation of the mist generator 26 is stopped until the atomization unit 28 is taken in and out. Therefore, the second and third embodiments are configured to switch the operation mode of the mist generator 26 to the normal operation mode when the power has already been turned on.

  Specifically, in the second embodiment, the mode is shifted to the normal operation mode based on the number of times the power is turned on. When the number of power-on times stored in the EEPROM 72 is “2” or more, the control device 70 omits the processing from Steps A1 to A4 shown in FIG. 8 and shifts to the normal operation mode in Step A5. As a result, when the power has already been turned on, it is possible to shift to the normal operation mode without changing the initial setting such as the mist function setting.

  Moreover, in 3rd Embodiment, it transfers to normal operation mode based on the temperature in a store | warehouse | chamber. If the internal temperature detected by the temperature sensor 61 is close to a predetermined value (for example, 1 to 4 ° C. which is a refrigeration temperature zone) when the power is turned on, the control device 70 performs the processing of steps A1 to A4. Skip to normal operation mode. Thereby, when the inside of the refrigerator compartment 3 is cold (that is, when it can be determined that the power has already been turned on), the mist generating device 26 is driven without changing the mist function setting. .

  According to the second and third embodiments, since the operation mode of the mist generating device 26 is switched based on the number of times the power is turned on or the temperature in the warehouse, the power supply is temporarily (or instantaneously) caused by a power failure, for example. Even if it is blocked, it is possible to avoid a situation in which the maintenance LED 53 is not turned on, that is, the user is prompted to perform unnecessary maintenance.

(Other embodiments)
The present invention is not limited to the above-described embodiment, and can be modified or expanded as follows.

  The installation location of the atomization unit 28 of the mist generator 26 may be in the refrigerator compartment 3 or the vegetable compartment 4. Moreover, the structure which uses not only an electrostatic atomizer but an ultrasonic atomizer etc. may be sufficient.

  The power supply to the mist generating device 26 is stopped when the door 3a of the refrigerator compartment 3 is opened, but the power supply is also stopped when the other doors (4a, 5a, 6a) are opened. Good. Thereby, safety can be further improved.

  Although the LED (light emitting diode) is used as the status indicator and the maintenance indicator, the present invention is not limited thereto, and for example, a filament light bulb (lamp), a light emitting element such as an organic EL, or a liquid crystal display may be used. Moreover, the color of each display is not limited to embodiment, You may use another color. For example, a so-called cold color (for example, blue or green) can be used for the status LED 52 to produce a clean image, and the maintenance LED 53 can have a so-called warning color (for example, red or red). The user's attention can be urged by using yellow).

Although the status LED 52 and the maintenance LED 53 are separately provided, for example, a two-color LED may be used in common. At this time, the maintenance LED 53 may be configured by using a plurality of LEDs having different colors, and the color to be turned on may be changed according to the content of the maintenance (cleaning, water supply, failure, etc.).
Although one month is set as the predetermined period when shifting to the maintenance mode, the present invention is not limited to this. What is necessary is just to set suitably by the capacity | capacitance of the water storage tank 33, etc.

  When determining whether the atomization unit 28 is taken in or out, the timer 71 may measure the transition time (the order in which the on / off is switched and the time interval) of each switch (9, 49, 50). For example, when the atomization unit 28 is attached again within a predetermined time (for example, several seconds) after the unit detection switch 49 detects that the atomization unit 28 has been removed, the atomization unit 28 is substantially Therefore, it may be determined that the maintenance has not been performed by estimating that the product has not been put in and out.

  The maintenance LED 53 may be provided outside the refrigerator compartment 3, for example, outside the operation panel 65 provided on the door 3a. In that case, it is good to light up, without opening the door 3a. Thereby, it is easily recognized by the user that it is a maintenance time.

  When the water detection means (permanent magnet 58 and magnetic sensors 59, 60) for detecting the presence or absence of water in the water storage tank 33 detects that there is almost no water in the water storage tank 33, the maintenance LED 53 May be lit. Thereby, before water runs out completely, replenishment of water can be urged. At this time, the power supply to the mist generator 26 may be stopped. As a result, idling can be prevented and useless power can be reduced, thereby saving power. Furthermore, even when it is detected that the atomization unit 28 has been detached after the power is turned on, if it is determined that there is no water in the water storage tank 33, the normal operation mode may not be entered.

  The measurement of the elapsed period by the timer 71 may be continued even when the mist function setting is off. Thereby, even if the operation mode is temporarily switched, the elapsed time is accumulated, so that it is possible to notify that the maintenance time is appropriate.

  The timer 71 is used to count up the elapsed time since the maintenance was performed, but the calendar function that stores the date when the maintenance was executed and turns on the maintenance LED 53 one month later. It is good also as a structure using.

  Although the mist generator 26 was illustrated as a power receiving unit, it is not restricted to this, For example, it is good also as a structure applied to an ozone deodorizing apparatus, a negative ion generator, etc. In this case, the door opening / closing and lid opening / closing determination steps shown in FIG. 11 may be applied by replacing the ozone deodorizing apparatus and the negative ion generating apparatus with the doors of the storage chambers and the accommodating portions that accommodate them. At this time, a configuration in which a status indicator and a maintenance indicator are provided in each of the ozone deodorizing device and the negative ion generating device may be used, or a configuration that is common to a plurality of power receiving units may be used.

  Further, the expression that the power receiving unit such as the mist generator 26 is “operable” is an expression including a state in which a failure such as a failure has not occurred. For example, in the case of the mist generating device 26, even if no water is stored in the water storage tank 33, it is an “operable state” as long as mist can be generated by replenishing water.

  In the second and third embodiments, the operation mode of the mist generating device 26 is switched based on the number of times the power is turned on or the temperature in the cabinet. However, both of these may be used as conditions for switching the operation mode. Further, the internal sensor is not limited to the temperature sensor 61, and other sensors may be used. For example, the above-described magnetic sensor (59, 60) may be used, or a humidity sensor that detects the humidity in the storage may be provided, and the operation mode may be switched based on the humidity in the storage.
