Description

  The present invention relates to a refrigerator configured to supply mist generated in an electrostatic atomizer to a storage room.

  Conventionally, in a refrigerator, a mist generator (an ultrasonic atomizer or an electrostatic atomizer) is provided in a vegetable room in a storage room, and the mist generated from the mist generator is supplied to the vegetable room. Therefore, the structure which maintains the freshness of vegetables is considered (for example, refer patent document 1). It is also considered that such a mist generator is used for sterilization and deodorization (for example, see Patent Document 2).

Japanese Patent No. 4179398 JP 2003-79714 A

However, when an ultrasonic atomizer is used as the mist generating device, the particle size of the mist is large, and the dirt component contained in the water stored in the mist generating device is also skipped as mist. May be supplied to the storage room.
On the other hand, in the case of using an electrostatic atomizer, the particle diameter of mist can be made fine (for example, several nm to several tens of nm level). For this reason, since the component of the dirt contained in the stored water of the mist generator can be prevented from being blown out as mist, it is preferable to use an electrostatic atomizer.

  In patent document 1, although the electrostatic atomizer is used, as the water for atomizing, the condensed water condensed on the atomization electrode by cooling the atomization electrode below the dew point of the vegetable room can be used. Or the defrost water produced when defrosting a cooler is used. However, it is difficult to stably obtain an appropriate amount of water in a configuration in which condensed water or defrosted water is used for atomization.

  In order to stably obtain the water for atomization, a water storage unit that is regularly replenished with water is provided, and the water is automatically supplied from the water storage unit to the mist generating device. On the other hand, if the user forgets to replenish water to the water storage unit, the water storage unit becomes empty, and as a result, mist cannot be generated and the freshness of vegetables cannot be maintained. Cause problems.

  The present invention has been made in view of the above circumstances, and the purpose thereof is a refrigerator equipped with an electrostatic atomization device having a water storage unit. An object of the present invention is to provide a refrigerator capable of generating negative ions effective for maintaining the freshness of food from an electrostatic atomizer even when mist is no longer generated.

In order to achieve the above object, the refrigerator of the embodiment includes a storage room in a refrigerated temperature zone, an electrostatic atomizer, one power supply device, and a power supply electrode. The electrostatic atomizer is provided with a water storage unit having a conductive water retention material having water retention and conductivity, and is provided in contact with the conductive water retention material, and water is supplied from the water storage unit and a negative voltage is applied thereto. The mist emission part which discharge | releases mist by this, and the ion generation conductor which generate | occur | produces a negative ion by applying a negative voltage. The electrostatic atomizer supplies the storage chamber with mist released from the mist discharger and negative ions generated by the ion generating conductor. The power supply device applies a negative voltage to the mist emitting part and the ion generating conductor. The power supply electrode is connected to the power supply device and is in contact with the conductive water retention material, and applies a negative voltage to the mist discharge portion through the conductive water retention material .

  According to the present invention employing the above-described configuration, mist can be discharged from the mist discharge portion when the water storage portion has moisture. When the user forgets to replenish water in the water storage unit and the water storage unit runs out of water, the mist is not released from the mist discharge unit. However, negative ions are still released from the ion generating conductor, and the freshness of the food is maintained by these negative ions.

Among these, the refrigerator compartment 3 and the vegetable compartment 4 are refrigeration temperature spaces in which the internal temperature is controlled to 1 to 4 ° C., for example, and both constitute storage rooms in the refrigeration temperature zone. Since the refrigerator compartment 3 and the vegetable compartment 4 are storage compartments in the same refrigerator temperature zone, they are partitioned vertically by a partition plate 7 formed of synthetic resin. The ice making room 5, the small freezing room, and the freezing room 6 of the other storage rooms constitute a freezing temperature range storage room. A heat insulating partition wall 8 partitions the vegetable compartment 4 below the refrigerated temperature zone and the ice making chamber 5 and the small freezer compartment in the freezing temperature zone immediately below it. Note that the small freezer compartment next to the ice making room 5 may be a temperature switching room in which the user can switch the set temperature.

  The front of each storage room (refrigeration room 3, vegetable room 4, ice making room 5, small freezer room, freezer room 6) is opened. The other vegetable room 4, ice making room 5, small freezer room and freezer room 6 are opened and closed by pull-out doors 4a, 5a and 6a, respectively. Each storage room is provided with a door switch (not shown) for detecting opening / closing of the corresponding door 3a, 4a, 5a, 6a.

  An electrostatic atomizer 9 is detachably installed in the front portion of the partition plate 7 that partitions the refrigerator compartment 3 and the vegetable compartment 4, and the configuration of the electrostatic atomizer 9 will be described below. 1 to 3 will also be described. The electrostatic atomizer 9 is disposed at a substantially central portion in the left-right direction at the front portion of the partition plate 7. In order to install the electrostatic atomizer 9, a base plate 10 is attached to the lower surface of the partition plate 7, and a unit accommodating portion for accommodating the atomizing unit 11 of the electrostatic atomizer 9 on the base plate 10. 12 is provided. The partition plate 7 is formed with an opening 13 for taking the atomizing unit 11 in and out, and a lid 14 for opening and closing the opening 13 is provided to be slidable in the front-rear direction.

  The atomization unit 11 of the electrostatic atomizer 9 includes a water storage tank 15 for storing water W (corresponding to a water storage part), an upper case (main case) 16 assembled on the upper part of the water storage tank 15, and an upper part thereof. It has a unit lid (lid body) 17 that covers the case 16 from above. Among them, the unit lid 17 is formed with a cylindrical water inlet 18 for pouring water into the water storage tank 15, and a detachable cap (plug member) 19 is provided at the upper end of the water inlet 18.

  The upper case 16 is provided with a sheet-like conductive water retention material 20, a water retention material 21, a water absorption pin 22, and a plurality of mist discharge portions 23. Among these, the conductive water retaining material 20 is formed by mixing polyester fiber and carbon fiber as a conductive substance into a felt shape (nonwoven fabric), for example, water retention, moisture uptake, and conductivity. And is arranged at the upper part in the upper case 16.

The water retaining material 21 is made of, for example, urethane sponge and has excellent water retention and moisture uptake properties, and is disposed in a state where the upper surface is in contact with the lower surface of the conductive water retaining material 20. The water retention material 21 is formed thicker than the conductive water retention material 20.
The conductive water retaining material 20 and the water retaining material 21 are filled between the upper case 16 and the unit lid 17 in a state where the conductive water retaining material 20 is stacked on the water retaining material 21.
The water absorption pin 22 is formed, for example, by twisting polyester fibers into a pin shape, and is excellent in water retention and moisture uptake. The water absorbing pin 22 has an upper end penetrating the water retaining material 21 and is in contact with the conductive water retaining material 20. Further, the lower end portion of the water absorption pin 22 is immersed in the water W in the water storage tank 15 through the cylindrical portion 16 a of the upper case 16.

  The mist releasing portion 23 is formed by mixing polyester fibers and carbon fibers as a conductive substance and twisting them to form a tapered rod shape at the tip portion. And has conductivity similar to the conductive water retention material 20. Each mist emitting portion 23 carries a platinum nanocolloid. The platinum nanocolloid can be supported, for example, by immersing the mist emitting part 23 in a treatment liquid containing the platinum nanocolloid and baking it. Each of the mist discharge portions 23 is attached to the bottom surface portion of the upper case 16 in a penetrating state, and the upper end portion is in contact with the conductive water retaining material 20.

  Moreover, the lower end part which makes the taper shape of each mist discharge | release part 23 protrudes in the state which hangs below the upper case 16. FIG. A discharge part cover 24 is detachably provided at the lower part of the upper case 16 so as to cover the mist discharge part 23. The discharge part cover 24 is formed with a mist outlet 25 located below the mist discharge part 23. A mist supply port 26 is formed in the base plate 10 so as to be positioned behind the mist outlet 25. The mist supply port 26 communicates with the mist outlet 25 of the atomization unit 11 and also communicates with the upper part of the vegetable compartment 4. Therefore, when mist is discharged from the mist discharge portion 23, the mist is supplied from the mist outlet 25 into the vegetable compartment 4 through the mist supply port 26 as shown by an arrow A in FIG. Yes.

  Here, the water absorption pin 22 sucks up the water W in the water storage tank 15 and supplies it to the water retaining material 21 and the conductive water retaining material 20. The water retaining material 21 and the conductive water retaining material 20 hold the water supplied from the water absorption pins 22 and supply the water to the mist discharge unit 23. In this case, the water absorption pin 22, the water retention material 21, and the conductive water retention material 20 constitute a water supply unit that supplies water to the mist discharge unit 23 from the water in the water storage tank 15, and supply the water to the mist discharge unit 23. It also has a function as a water reservoir for storing water.

  When the atomizing unit 11 is taken out from the unit accommodating portion 12 in order to supply water to the water storage tank 15 or to clean the mist discharging portion 23, it slides forward as shown by an arrow B1 in FIG. Then, the atomization unit 11 is lifted and removed from the opening 13. In addition, when the atomizing unit 11 is set in the unit accommodating portion 12 after replenishing water to the water storage tank 15 or cleaning the mist discharge portion 23, the lid 14 is pushed backward to open the opening portion 13. In the opened state, as shown by an arrow B2 in FIG. 3, after being inserted into the unit accommodating portion 12 from the opening portion 13, it is slid rearward to be set at a normal set position.

  As shown in FIG. 2, the atomizing unit 11 is provided with a power receiving pin 27 so as to protrude rearward. When the atomizing unit 11 is set at a proper position in the unit housing portion 12, the tip end portion of the power receiving pin 27 is inserted and connected to the connector 28 provided on the base plate 10 side. The connector 28 is connected to one end on the secondary side of a high voltage transformer (not shown) included in the power supply device 29 shown in FIG.

  A power supply electrode 30 is connected to the base end portion of the power receiving pin 27. As shown in FIG. 1, the distal end portion of the power supply electrode 30 is inserted from below into an upward cylindrical holding member 31 passing through the water retaining material 21 in the upper case 16. A circular conductive plate 32 having a diameter larger than that of the pressing member 31 is provided at the tip (upper end) of the power supply electrode 30. The conductive plate 32 is pressed and electrically connected to the conductive water retaining material 20 by the pressing member 31.

  The power supply device 29 applies a negative high voltage to the power supply electrode 30 in the form of pulses, and the negative high voltage applied to the power supply electrode 30 is supplied to each mist through the conductive water retention material 20. Applied to the emitting part 23. When a negative high voltage is applied to each mist emitting portion 23, an ion wind is generated by a spontaneous discharge phenomenon at a portion protruding downward from the upper case 16 of each mist emitting portion 23, and surface water is generated by this ion wind. Is split and released as fine mist (for example, several nm to several tens of nm level). In the electrostatic atomizer 9 of the present embodiment, the counter electrode for the mist emitting unit 23 is not installed in the vicinity of the mist emitting unit 23. However, the present invention does not deny that a counter electrode for the mist emitting portion 23 is installed in the vicinity.

  In addition to the mist emitting part 23, the atomizing unit 11 is also provided with an ion generating conductor 33 that generates negative ions in order to maintain the freshness of vegetables (food). The ion generating conductor 33 is disposed in the discharge portion cover 24, and a base end portion is connected to a middle portion of the power supply electrode 30. Therefore, a negative high voltage is applied to the ion generating conductor 33 by the same power supply device 29 as the mist emitting unit 23. The tip of the ion generating conductor 33 is formed in a tapered needle shape, and when a negative high voltage is applied, a discharge occurs and negative ions are generated in the discharge portion cover 24. In the present embodiment, the counter electrode for the ion generating conductor 33 is not provided in the vicinity of the ion generating conductor 33, but the counter electrode may be provided in the vicinity.

  In the vegetable compartment 4, as shown in FIG. 4, a lower container 34 and an upper container 35 disposed on the upper part of the lower container 34 are provided. The upper container 35 is formed to have a length in the front-rear direction smaller than that of the lower container 34, and is disposed on the rear side of the lower container 34. A front end portion of the upper container 35 is positioned below the mist supply port 26 of the base plate 10. In this state, when mist and negative ions are released from the mist supply port 26 into the vegetable compartment 4, the mist is supplied to both the lower container 34 and the upper container 35.

  A control device (control means) including a microcomputer is provided on the back of the refrigerator body 1. This control device has a function of controlling the entire operation of the refrigerator main body 1 such as a compressor of a refrigeration cycle and a power supply device 29 of the electrostatic atomizer 9. In particular, for the power supply device 29 of the electrostatic atomizer 9, the control device detects the closing of the door by the door switch of each storage chamber, and the set state of the atomization unit 11 in the unit accommodating portion 12 A detection switch (not shown) for detecting the set detects the set, and further, a lid switch (not shown) for detecting that the lid 14 of the unit accommodating portion 12 has closed the opening portion 13 detects the closing. Driving is allowed, but when any storage chamber door is opened, or when the atomization unit 11 is not set or the lid 14 is opened, the driving is stopped. .

  The operation of the above configuration will be described. When water is stored in the water storage tank 15, the atomization unit 11 is set in the unit housing portion 12, the lid 14 of the unit housing portion 12 is closed, and the doors of the respective storage chambers are closed. The power supply device 29 is driven. When the power supply device 29 is driven, a negative high voltage is applied to each mist emitting portion 23 via the power supply electrode 30 and the conductive water retention material 20, and a negative high voltage is applied to the ion generating conductor 33. Is done. Then, fine mist is discharged into the discharge portion cover 24 from the lower portion of each mist discharge portion 23. In addition, a discharge occurs from the tip portion of the ion generating conductor 33, particularly, a tapered shape, and negative ions are generated in the discharge portion cover 24.

  The mist and negative ions generated in the discharge portion cover 24 are supplied from the mist outlet 25 into the upper container 35 and the lower container 34 of the vegetable compartment 4 through the mist supply port 26. The mist contains hydroxy radicals having a strong oxidizing action, and the fine mist containing the hydroxy radicals is supplied into the upper container 35 and the lower container 34 of the vegetable room 4 so that their sterilization and deodorization can be prevented. It becomes possible. Moreover, the freshness maintenance of the vegetables etc. which were accommodated in the upper container 35 and the lower container 34 by the mist can be expected. On the other hand, the negative ions can be kept fresh, sterilized and deodorized.

By the way, in the atomization unit 11, the water in the water storage tank 15 gradually decreases due to the discharge of mist from the mist discharge unit 23. For this reason, it is necessary to periodically supply water to the water storage tank 15. If this water supply is forgotten, there will be no water in the water storage tank 15, and eventually the water that has been sucked up by the water retention material 21 or the conductive water retention material 20 will also disappear. Then, even if a negative high voltage is applied from the power supply electrode 30 to the mist emitting part 23 via the conductive water retaining material 20, the mist is not emitted from the mist emitting part 23.
However, in the present embodiment, the discharge is still continued from the ion generating conductor 33, and negative ions are continuously generated. For this reason, the freshness keeping effect, sterilization, and deodorizing effect by negative ions are continued.

  Thus, according to this embodiment, since the negative high voltage is applied to the mist emitting part 23 and the ion generating conductor 33 by the single power supply device 29, the water in the water storage tank 15 disappears, and the mist Even if mist is no longer released from the discharge portion 23, negative ions generated by the ion generating conductor 33 can be supplied into the vegetable compartment 4. For this reason, the freshness preservation, sterilization, and deodorizing effect of vegetables can be obtained continuously.

  Moreover, in this embodiment, as the electrostatic atomizer 9, in particular, the counter electrode of the mist emitting part 23 and the counter electrode of the ion generating conductor 33 are installed in the vicinity of the mist emitting part 23 and the ion generating conductor 33. Therefore, corona discharge generated when the counter electrode is provided is eliminated, and generation of harmful gases such as ozone can be suppressed.

  In the electrostatic atomizer 9 in the second embodiment, the ion generating conductor 36 is provided in the discharge portion cover 24 as in the first embodiment. The ion generating conductor 36 is bent in a zigzag shape. With such an ion generating conductor 37, negative ions are generated not only from the tip but also from the corners of the plurality of bent portions 36a, so the amount of negative ions that can be supplied to the vegetable compartment 4 increases.

(Third embodiment)
FIG. 6 shows a third embodiment of the present invention. In the electrostatic atomizer 9 according to the third embodiment, metal plating is performed on the outer surface of any one of the plurality of mist emitting portions 23a, and this metal plating is used as an ion generating conductive material.

In this embodiment, a negative high voltage is applied from the power supply electrode 30 via the conductive water retention material 20. For this reason, a negative high voltage can be applied to the ion generating conductor 37 even if the conductive water retaining material 20 runs out of water.
In addition, the mist discharge | release part which provides the ion generating conductor 37 by metal plating may be plural, and the mist discharge | release part which has the mist discharge | release capability normally should just be left.

One end of the ion generating conductor 38 in the mist emitting portion 23 is brought into contact with the conductive water retaining material 20, and the other end is slightly protruded outward from the mist generating portion.
In this way, since the ion generating conductor 38 is passed through the mist emitting portion 23a, the mist emitting ability of the mist emitting portion 23a is not impaired. Further, since the ion generating conductor 38 functions as a reinforcing material, the strength of the mist emitting portion 23a through which the ion generating conductor 38 is passed is improved.

(Fifth embodiment)

The connecting conductor 42 extends, for example, through the conductive water retaining material 20 toward the conductive plate 32 side of the power supply electrode 30 and is in contact with the conductive plate 32.

  Thus, if the ion generating conductor 41 is in direct contact with the power supply electrode 30, the electrical resistance between the power supply electrode 30 and the ion generating conductor 41 is reduced. In addition, since water has conductivity, when the water retaining material 21 contains water, a negative high voltage can be applied to the mist discharging portion 23 through the water in the water retaining material 21. It is possible to omit the water retaining material 20.
