Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same symbols are assigned to the same parts. These names and functions are the same. Therefore, detailed explanations for these are not repeated.

(First Embodiment)

FIG. 1 is an overall front view of a refrigerator 100 according to this embodiment. The ion generating unit 110 according to the present embodiment is mounted on, for example, a refrigerator 100 as an example of a refrigerating device shown in FIG. 1. In addition, the refrigerating device may be a storage compartment that does not accompany cooling, such as a kitchen drawer, cabinet, or closet.

The refrigerator 100 includes, for example, a main body 101 and doors 102L and 102R. In addition, the main body 101 includes a main refrigerating space 103, a freezing space 105, a vegetable storage space 106, and a fruit storage space. Room 107, ice storage space 108, etc. In the present embodiment, a refrigerated space 104 is provided in the main refrigerated space 103, and an ion generating unit 110 for the refrigerated space 104 is mounted in the refrigerated space 104.

FIG. 2 is a side view of the cold air pipe 131 according to this embodiment. FIG. 3 is a side cross-sectional view showing the vicinity of the refrigerated space 104 in the present embodiment. Referring to FIG. 3, the refrigerating space 104 of this embodiment is mainly formed of an upper box 104B mounted on the inner wall of the main refrigerating space 103, and a lower box 104A slidable forward and backward relative to the main refrigerating space 103 or the upper box 104B.

Behind the refrigerated space 104, as shown in FIG. 2, a cooling air pipe 131 is provided. A part of the cold air flowing through the cooling air pipe 131 flows from the outlet 133 along the outer wall of the lower box 104A or the upper box 104B, and indirectly cools the inside of the refrigerated space 104 . Therefore, it is possible to prevent the cold air from directly contacting the food and beverage in the refrigerated space 104 and to cool the food and beverage without drying it.

An ion generating unit 110 is disposed behind the upper box 104B. In addition, an opening 104X is provided on the back of the upper case 104B, and the positive and negative ions generated by the ion generating unit 110 flow into the refrigerated space 104 through the opening 104X.

FIG. 4 is a plan view of the refrigerated space 104 in the present embodiment. Referring to FIG. 4, a conductive plate 120 is disposed on the bottom surface inside the lower case 104A. As described later, the degree of deviation of the positive and negative ions generated by the ion generating unit 110 can be reduced by the conductive plate 120.

FIG. 5 is a side sectional view showing the vicinity of the ion generating unit 110 according to the present embodiment. The ion generating unit 110 of the present embodiment is installed in an installation space 113 formed by an inner wall of the refrigerator 100. The periphery of the front part of the installation space 113 is connected to the upper case 104B through a gasket 118. In this embodiment, the ion generating unit 110 includes a brush-shaped discharge electrode 1,2 and generates a high concentration of ions near the brush-shaped discharge electrode 1,2. A slit 1150 is arranged in front of the discharge electrodes 1 and 2 so that items do not enter each other between the ion generating unit 110 and the refrigerating space 104.

Here, the structure of the ion generating unit 110 according to this embodiment will be described. FIG. 6 shows the internal structure of the ion generating unit 110 according to this embodiment. The ion generating unit 110 includes two discharge electrodes 1,2, a ring-shaped induction electrode 3,4, and two rectangular printed substrates 5,6. The induction electrode 3 is an electrode for forming an electric field with the discharge electrode 1. The sensing electrode 4 is an electrode for forming an electric field between the sensing electrode 4 and the discharge electrode 2. The discharge electrode 1 is an electrode for generating negative ions between the discharge electrode 1 and the induction electrode 3. The discharge electrode 2 is an electrode for generating positive ions between the discharge electrode 2 and the induction electrode 4.

The printed substrates 5 and 6 are arranged in parallel at a predetermined interval. The sensing electrode 3 is a surface formed on one end portion of the printed substrate 5 in the longitudinal direction using a wiring layer of the printed substrate 5. A hole 5 a is formed inside the sensing electrode 3 and penetrates the printed substrate 5. The sensing electrode 4 is formed on the surface of the other end portion in the longitudinal direction of the printed substrate 5 using the wiring layer of the printed substrate 5. A hole 5 b penetrating the printed circuit board 5 is provided inside the sensing electrode 4.

Each of the discharge electrodes 1,2 is disposed perpendicularly to the printed substrates 5,6. A base end portion of the discharge electrode 1 is inserted into a hole of the printed substrate 6, and the other end penetrates the center of the hole 5 a of the printed substrate 5. A base end portion of the discharge electrode 2 is inserted into a hole of the printed substrate 6, and the other end penetrates the center of the hole 5 b of the printed substrate 5. The base end portion of each of the discharge electrodes 1 and 2 is fixed to the printed circuit board 6 by solder.

The sensing electrodes 3 and 4 are formed on a printed substrate 5, and the discharge electrodes 1,2 are fixed to a printed substrate 6 different from the printed substrate 5. Therefore, in a state where dust is accumulated on the printed substrates 5 and 6, even when the ion generating device is in a high-humidity environment, the current leakage between the discharge electrodes 1,2 and the induction electrodes 3, 4 can be suppressed and stable. Ground produces ions.

The front end portion of each of the discharge electrodes 1 and 2 is formed in a brush shape. The discharge electrode 1 includes a plurality of wire-shaped conductors 7 provided at a front end portion thereof, and a bonding portion 7 a with a root element that bundles the plurality of conductors 7. The discharge electrode 2 includes a plurality of wire-shaped conductors 8 provided at a front end portion thereof, and a bonding portion 8 a with a root element that bundles the plurality of conductors 8.

FIG. 7 is a circuit diagram of the ion generating unit 110 according to this embodiment. 7, the ion generating unit 110 includes a power supply terminal T1, a ground terminal T2, diodes 32, 33, and a step-up transformer 31 in addition to the discharge electrodes 1,2 and the induction electrodes 3, 4. A positive terminal and a negative terminal of a DC power supply are connected to the power terminal T1 and the ground terminal T2, respectively. A DC power supply voltage (for example, + 12V or + 15V) is applied to the power terminal T1, and the ground terminal T2 is grounded. The power terminal T1 and the ground terminal T2 are connected to the step-up transformer 31 through the power circuit 30.

The step-up transformer 31 includes a primary winding 31a and a secondary winding 31b. One terminal of the secondary winding 31 b is connected to the sensing electrodes 3 and 4, and the other terminal is connected to the cathode of the diode 32 and the anode of the diode 33. The anode of the diode 32 is connected to the base end portion of the discharge electrode 1, and the cathode of the diode 33 is connected to the base end portion of the discharge electrode 2.

The operation of the ion generating unit 110 will be described with reference to FIGS. 6 and 7. When a DC power supply voltage is applied between the power supply terminal T1 and the ground terminal T2, a charge is charged in a capacitor (not shown) included in the power supply circuit 30. The electric charge charged in the capacitor is discharged through the primary winding 31a of the step-up transformer 31, and a pulse voltage is generated in the primary winding 31a.

When the primary winding 31a generates a pulse voltage, in the secondary winding 31b, positive and negative high-voltage pulses are generated while being alternately attenuated. A negative high-voltage pulse is applied to the discharge electrode 1 through the diode 32, and a positive high-voltage pulse is applied to the discharge electrode 2 through the diode 33. As a result, corona discharges are generated at the conductors 7 and 8 at the tips of the discharge electrodes 1 and 2 and negative ions and positive ions are generated, respectively.

In addition, the positive ion is a cluster ion in which a plurality of water molecules cluster around a hydrogen ion (H <+>), and is expressed as H <+> (H ₂ O) m (m is an arbitrary integer of 0 or more). The negative ion is a cluster ion in which a plurality of water molecules cluster around the oxygen ion (O ₂ <->), and is expressed as O ₂ <-> (H ₂ O) n (n is an arbitrary integer of 0 or more). In addition, when positive ions and negative ions are released into the room, the two ions surround the bacteria or viruses suspended in the air and cause chemical reactions on the surfaces. By the action of the hydroxide radical (‧OH) of the active species generated at this time, planktonic bacteria and the like are removed.

In addition, in the present embodiment, the plurality of wire-shaped conductors 7 and 8 constituting the front end portion of the brush-shaped discharge electrode 1,2 are electrically mutually exclusive and electrically attracted to the induction electrodes 3, 4 respectively. On the other hand, when bending outward, the area of the area where the front ends of the conductors 7 and 8 exist is increased. That is, the area of the area where ions are generated becomes larger, and the amount of ions generated when the same voltage is applied is increased compared to the needle-shaped discharge electrode.

The refrigerator 100 or the ion generating unit 110 of this embodiment is not provided with a fan for releasing ions into the refrigerated space 104. This prevents the food and drink from being blown into the refrigerated space 104 by the wind, so that drying of the food and drink can be suppressed. On the other hand, the positive and negative ions generated by the conductors 7 and 8 at the front ends of the discharge electrodes 1 and 2 are not released to the refrigerated space 104 by the wind force of the fan, so it is difficult to uniformly spread both ions of the positive and negative ions across Wide range in refrigerated space 104.

However, in the refrigerated space 104 of this embodiment, as shown in FIG. 8, the potential variation of the conductive plate 120 makes it difficult for the positive and negative ions to deviate. As a result, bacteria can be efficiently removed or made inert.

In more detail, as shown in FIG. 26, in a general refrigerator, when a positive or negative cluster ion diffuses due to natural convection, etc., the charge state of the wall material is used between the cluster ion and the wall surface according to Coulomb's law. Cause repulsion. In general, the wall material is mostly made of electrically insulating materials such as resin, which hardly cause the charge to move in the wall surface. Therefore, the charged state is different at each wall surface. As a result, the lack of positive ions and negative ions is everywhere in the wall surface. The balance and sterilization ability are reduced. However, in this embodiment, since the conductive plate 120 is disposed at the bottom of the refrigerated space 104, the bottom of the conductive plate 120 is disposed without depending on the charged state of each place. The potential at the bottom is the same. Therefore, the local imbalance of positive ions and negative ions at the bottom can be improved.

In this embodiment, the imbalance between positive ions and negative ions in the entire vicinity of the bottom in the refrigerated space 104 is further improved. That is, if there are many positive ions near the bottom in the refrigerated space 104, more positive ions are obtained by the conductive plate 120, and the conductive plate 120 is positively charged. When the conductive plate 120 is positively charged, the attractive force to negative ions increases and the repulsive force to positive ions increases. Therefore, many negative ions are attracted to the vicinity of the bottom in the refrigerated space 104. When there are many negative ions near the bottom in the refrigerated space 104, more negative ions are obtained by the conductive plate 120, and the conductive plate 120 is negatively charged. When the conductive plate 120 is negatively charged, the attractive force to positive ions increases and the repulsive force to negative ions increases.

Therefore, in the vicinity of the conductive plate 120, positive ions or negative ions easily exist in a balanced manner, and bacteria can be efficiently removed or inertized by the reaction between positive ions and negative ions.

Furthermore, it is preferable that the upper box 104A or the lower box 104B does not contain a pigment such as titanium oxide or carbon or the like. That is, it is preferable that members in the refrigerated space 104 itself or in the vicinity of the refrigerated space 104 easily become electrically neutral, and do not have a polarity due to a molecular structure. This makes it possible to suppress the imbalance between the positive ions and the negative ions near the side walls of the upper case 104A or the lower case 104B where the conductive plate 120 is not disposed.

(Second Embodiment)

In the first embodiment, the conductive plate 120 is disposed on the entire bottom surface of the lower case 104A in the refrigerated space. However, it is not limited to this configuration. For example, as shown in FIG. 9, the plate 120 may be disposed on the front side of the bottom surface of the refrigerated space 104. As shown in FIG. 10, the conductive plate 120Y may be disposed in front of the refrigerated space 104.

Since the ions do not easily reach the area far from the ion generating unit 110, the amount of ions tends to decrease. Therefore, by arranging a conductive plate in a region away from the ion generating unit 110, the imbalance between the positive ions and the negative ions can be improved. Therefore, even with a small amount of ions, bacteria can be efficiently removed or made inert. On the other hand, since the amount of ions is sufficient in a region close to the ion generation unit 110, even if an imbalance of positive ions and negative ions is generated, it is possible to supply both positive and negative ions sufficient to remove bacteria or make them inert. ion. Therefore, compared with the first embodiment, it is possible to reduce the usage amount of the conductive plate member 120.

Alternatively, as shown in FIG. 11, two conductive plates 122A and 122B may be arranged in the lower box 104A of the refrigerated space. In addition, a plurality of conductive plates 122A, 122B, ... may be arranged in an array in accordance with the size of the refrigerated space 104, or a plurality of conductive plates 122A, 122B, ... may be arranged in an overlapping manner.

Alternatively, as shown in FIG. 12, one or more conductive plates 123A, 123B, etc. may be arranged in the refrigerated space 104. This makes it possible to easily maintain the balance of the positive and negative ions around the food and drink arranged on the plates 123A, 123B,...

In this way, as a conductive plate member, it is not necessary to be a relatively large piece of plate member, and thus the cost can be reduced. In addition, when the food is taken out with the conductive plate, it is not necessary to remove all the food in the refrigerated space 104 when the conductive plate is to be removed when the conductive plate is contaminated or damaged.

(Third Embodiment)

Further, for example, as shown in FIG. 13, the conductive plate 120X may have an L-shape in side view covering the bottom surface of the lower case 104A and the lower portion of the front surface. Further, as shown in FIG. 14, the conductive plate 120Z may have a U-shape in side view covering the bottom surface of the lower case 104A, the lower portion of the front surface, and the lower portion of the rear surface.

Alternatively, as shown in FIG. 15, conductive plates 120 and 120B may be disposed on each of the bottom surface and the upper surface of the refrigerated space 104. Thereby, the balance of positive ions and negative ions can be easily maintained in all regions of the refrigerated space 104.

Furthermore, as shown in FIG. 16, conductive plates 120, 120B, 120C, and 120D may be disposed on each of the bottom surface, the upper surface, and the side surfaces of the refrigerated space 104. Thereby, the balance of positive ions and negative ions can be easily maintained in all regions of the refrigerated space 104.

As described above, in this embodiment, compared with the first embodiment, there is an effect that the food stored in the height direction in the refrigerated space 104 can maintain a balance between positive ions and negative ions.

(Fourth embodiment)

In the first to third embodiments, the refrigerating space 104 has a conductive plate 120. However, it is not limited to this configuration. For example, as shown in FIG. 17, a conductive mesh member 127 may be disposed in the refrigerated space 104. Moreover, it may be a conductive slit-shaped member. Furthermore, a conductive film may be arranged on the surface forming the refrigerated space 104.

(Fifth Embodiment)

In addition, as shown in FIG. 18, the conductive plate 120 or the mesh member 127 may be electrically connected to the secondary winding side of the ion generating unit 110. More specifically, a conductive plate 120, a mesh member 127, or the like is electrically connected to a secondary-side intermediate potential of the induction electrodes 3, 4 or the like of the ion generating unit 110 through a connector 119 or the like. Thereby, the potential of the conductive plate 120 or the mesh member 127 can be stabilized at an intermediate potential with respect to the generated ions. Therefore, the electric field in the refrigerated space 104 is stable, and the balance between the positive ions and the negative ions can be easily maintained throughout a wide area.

The conductive plate 120 or the mesh member 127 is preferably the ground potential of the refrigerator 100. In addition, when the doors 102L and 102R are opened, it is preferable that the electrical connection between the conductive plate 120 or the mesh member 127 and the secondary winding side of the ion generating unit 110 is cut off. At this time, it is better to leave The driving of the sub-generation unit 110 is also stopped. Thereby, the possibility that a user contacts the conductive plate 120 or the mesh-like member 127 and gets an electric shock can be eliminated.

(Sixth embodiment)

In the first to fifth embodiments, a conductive plate 120 is provided in the refrigerated space 104. However, it is not limited to this configuration. As shown in FIG. 19, a conductive plate 124X may be disposed outside the refrigerating space 104, for example, in the main refrigerating space 103 and facing the bottom of the lower box 104A of the refrigerating space.

Alternatively, as shown in FIG. 20, the conductive plate 124Y may constitute a part of the lower case 104Y of the refrigerated space, such as a bottom surface or a front face, or a part of the upper case 104B.

Alternatively, as shown in FIG. 21, a conductive material may be mixed into the lower case 104Z or the upper case 104B of the refrigerated space and formed.

(Seventh embodiment)

In the first to sixth embodiments, the conductive plate 120 is provided in the refrigerated space 104. However, it is not limited to this configuration. As shown in FIG. 22, an ion generating unit 110B may be provided to supply ions to the vegetable storage space 106 or the fruit storage space 107, which preferably prevents direct cooling air from flowing. The ion generating unit 110B does not use a fan to supply positive ions and negative ions to the vegetable storage space 106 or the fruit storage space 107. In this case, it is preferable to arrange a conductive plate 120 or the like in the vegetable storage space 106 or the fruit storage space 107.

In addition, as a matter of course, the position of the vegetable box or the fruit box is not limited to the form shown in FIG. 1. For example, as shown in FIG. 23, the vegetable storage space 106 or the fruit storage space 107 may be provided in the main refrigerated space 103.

(Eighth embodiment)

In addition, more preferably, ions may be supplied to the main refrigerating space 103, the freezing space 105, or the ice storage space 108 shown in FIG. Positive and negative ions may be blown into the area together with cold air by a fan. The details will be described with reference to FIGS. 2 and 24. In addition, FIG. 24 is a rear view of the cold air pipe 131 according to this embodiment.

In the present embodiment, the ion generating unit 110C is arranged in the middle of the passage of the main cold air flowing by the fan 132, for example, the lower part of the cold air pipe 131. Thereby, cold air, positive ions, and negative ions are blown into the main refrigerating space 103 or the freezing space 105 from the blow-out port 131X by the air supplied from the fan 132. On the other hand, with regard to the refrigerated space 104, the vegetable storage space 106, or the fruit storage space 107, cold air is not blown directly, that is, balanced supply of positive ions and negative ions is performed while indirectly cooling.

(Ninth Embodiment)

In the first to eighth embodiments, the refrigerator 100 for household use has been described as an example of the refrigerator. However, the present invention is not limited to such a configuration. For example, as shown in FIG. 25, a storehouse of a size that can be accessed by a person can also use the techniques of the first to eighth embodiments.

In more detail, conductive plates 125, 125, ..., or a mesh member 127 may be placed on the racks 251, 251,... Thereby, the positive ions and the negative ions supplied from the ion generating device 210 can exist in a balanced manner around the frames 251, 251 ....

In addition, the storage can also be a drawer, cabinet, or wardrobe in a kitchen or the like.

(Tenth embodiment)

As described below, the ion generating unit 110 of the above embodiment can be combined with its surrounding structure to realize an ion generating device 1100 in which a conductor is stored in a predetermined storage area. Hereinafter, for convenience of explanation, the body of the ion generating unit 110 according to the first to ninth embodiments is referred to as an ion generating unit 110, and a system combining the body of the ion generating unit 110 and its surroundings is referred to as an ion generating device 1100.

The ion generator 1100 according to this embodiment is mounted on, for example, a refrigerator 100 as an example of a storage compartment shown in FIG. 27. In addition, the storage compartment may be a drawer, a microwave, a cabinet, or a wardrobe in a kitchen or the like. A storage compartment such as a refrigerator 100 generally includes a main body 101 and a door 102.

The ion generator 1100 is arranged in the food storage space 103 of the refrigerator 100 shown in FIG. 28. For example, the ion generating device 1100 is disposed on the back of the food storage space 103, the back of the refrigerated box (refrigerated space) 104, the back of the fruit box (fruit space) 107, or the back of the vegetable box (vegetable space) 106, and the like. Ions are supplied in 103 or in refrigerator 104, fruit box 107, or vegetable box 106.

FIG. 29 is a side cross-sectional view showing the ion generator 1100 and the drawer 109 according to this embodiment. FIG. 30 is an enlarged side sectional view showing the vicinity of the ion generating device 1100 according to this embodiment. As shown in FIGS. 29 and 30, the ion generating device 1100 of this embodiment is mainly composed of an installation space 113, an ion generating unit 110, and a recessed portion 114. The ion generating unit 110 includes a brush electrode 112.

The installation space 113 is formed on the back surface of the food storage space 103 of the refrigerator 100, for example. An end portion on the food storage space 103 side of the installation space 113 is an ejection port 113X of ions generated by the brush electrode 112.

The ion generating unit 110 is disposed inside the installation space 113. The ion generating unit 110 includes a brush electrode 112 as a discharge electrode, an induction electrode (not shown), a circuit board, and the like. Ions are generated between the brush electrode 112 and the sensing electrode. The generated ions are ejected from the ejection port 113X toward the food storage space 103 by diffusion.

The configuration of the ion generating unit 110 is not particularly limited, and for example, the configuration described in Patent Document 2 can be adopted. That is, the brush-shaped electrode 112 has a plurality of wire-shaped conductors (referred to simply as brushes) at its front end, and a joint portion with the root element that bundles the plurality of conductors. The conductor is made of, for example, metal, carbon fiber The dimension structure preferably has an outer diameter of 5 μm or more and 30 μm or less. In addition, it is preferable that the conductor protrude from the joint by 3 mm or more.

A recess 114 is formed between the ejection port 113X of the installation space 113 and the ion generating unit 110 toward the lower side. The depth H of the recess 114 is preferably longer than the length of the wire-shaped conductor. For example, it is preferable that the recessed portion 114 is deeper than 3 to 4 mm.

As a result, if the conductor is detached from the brush electrode 112, it will also fall to the receiving area, that is, the recess 114. That is, the conductor can be accommodated in a predetermined storage area.

(Eleventh Embodiment)

In this embodiment, as shown in FIG. 31, in addition to the ion generating device 1100 of the tenth embodiment, a brush passage prevention portion 115 is provided between the ejection port 113X and the brush electrode 112. The brush passage prevention portion 115 is composed of a mesh, a net, a slit, or the like. Preferably, the brush passage prevention portion 115 is provided near the ejection port 113X. Thereby, it is possible to prevent the user from accidentally contacting the brush-shaped electrode 112 by the brush passage prevention portion 115.

The size of the gap of the brush passage prevention portion 115 is preferably a size that is shorter than the length of the conductor and that ions can easily pass through. For example, it is preferably several mm, more preferably 4 mm or less and 2 mm or more.

As a result, assuming that the conductor is detached from the brush-shaped electrode 112, the possibility of the conductor moving outside the predetermined storage area can be further reduced by the brush passing through the prevention portion 115.

(Twelfth Embodiment)

In this embodiment, as shown in FIG. 32, in addition to the ion generating apparatus 1100 of the tenth or eleventh embodiment, a brush attachment portion 116 is provided near the ejection port 113X. The surface of the brush attachment portion 116 is composed of a raised surface such as Magic Tape (registered trademark) or an adhesive surface such as an adhesive tape.

In addition, when the conductor is a metal standard, a magnet may be disposed on the surface or inside the installation space 113. Alternatively, when the conductor is of a specification with a high possibility of being charged, a charge may be applied to the bottom surface of the installation space 113.

Therefore, if the conductor is detached from the brush electrode 112, the possibility of the conductor moving outside the predetermined storage area can be further reduced by the brush attachment portion 116.

In addition, the brush attachment portion 116 is not limited to be provided on the bottom surface of the installation space 113, and may be provided on a side surface or a top surface of the installation space 113.

Alternatively, the brush attachment portion 116 may be provided on a side surface or a bottom surface of the recessed portion 114. Thereby, the possibility that the conductor falling into the recessed portion 114 returns to the installation space 113 can be reduced, and as a result, the possibility that the conductor moves outside the predetermined storage area can be further reduced.

(Thirteenth embodiment)

In this embodiment, as shown in FIG. 33, in addition to the configuration of the ion generating device 1100 of the tenth to twelfth embodiments, the ion generating unit 110 of the ion generating device 1100 is fixed to the main body 101 side of the refrigerator 100 and generates ions with ions. The recessed portion 114 of the device 1100 is easily vibrated relative to the main body 101 of the refrigerator 100. The recessed portion 114 is attached to the main body 101 through a spring 117 and the like.

With this, for example, when the drawer 109 or the like is closed, the back surface of the drawer 109 touches the wall surface of the food storage space 103, and the recessed portion 114 easily vibrates. As a result, the conductive body attached to the upper portion of the concave portion 114 easily falls into the bottom surface of the concave portion 114, which reduces the possibility that the conductive body falling into the concave portion 114 returns to the installation space 113 again. As a result, it is possible to further reduce the movement of the conductive body outside the predetermined storage area Possibility.

Conversely, as shown in FIG. 34, the recess 114 of the ion generating device 1100 may be fixed on the body 101 side of the refrigerator 100, and the ion generating unit 110 of the ion generating device 1100 may easily vibrate relative to the body 101 of the refrigerator 100. The ion generating unit 110 or the installation space 113 is attached to the body 101 through a spring 117 and the like.

Thereby, for example, when the drawer 109 or the like is closed, the back surface of the drawer 109 touches the wall surface of the food storage space 103, and the installation space 113 or the ion generating unit 110 easily vibrates. As a result, the conductive body located in the installation space 113 or the ion generating unit 110 easily falls into the recessed portion 114. As a result, the possibility that the conductive body moves outside the predetermined storage area can be further reduced.

Alternatively, as shown in FIG. 35, the installation space 113 and the recess 114 may be transmitted through the spring 117 so that the installation space 113 of the ion generating device 1100 and the ion generating unit 110 and the recess 114 easily vibrate relative to the body 101 of the refrigerator 100. It is mounted on the body 101.

Thereby, for example, when the drawer 109 is closed, the back surface of the drawer 109 touches the wall surface of the food storage space 103, and the installation space 113, the ion generating unit 110, or the recessed portion 114 easily vibrates. As a result, the conductor located in the installation space 113 or the ion generating unit 110 easily falls into the recessed portion 114, and the conductor located on the upper portion of the recessed portion 114 also easily falls into the bottom of the recessed portion 114, which can further reduce the possibility of the conductor moving outside the predetermined storage area. .

(Fourteenth embodiment)

In this embodiment, as shown in FIG. 36, the ion generating apparatus 1100 includes a brush passage prevention portion 115 of the eleventh embodiment and a brush attachment portion 116 of the twelfth embodiment, but the recess 114 is not formed.

As a result, assuming that the conductor is detached from the brush-shaped electrode 112, the conductor can also be stopped in advance by the brush passage prevention portion 115 and the brush attachment portion 116. Therefore, in the event that the conductive body is detached from the brush electrode 112, the possibility of the conductive body moving outside the predetermined storage area can also be reduced.

(Fifteenth embodiment)

In addition, instead of forming the concave portion 114 provided further downward from the bottom surface of the installation space 113 in the tenth embodiment, the brush passage prevention portion 115B provided upward from the bottom surface of the installation space 113 shown in FIGS. 37 and 38 may be used.

In other words, instead of covering the entire member of the ejection opening 113X like the brush passage prevention portion 115 of the eleventh embodiment, the brush passage prevention portion 115B covering the lower portion of the ejection outlet 113X may be used.

That is, it is not limited to the recessed portion 114, and a space lower than both of the brush electrode 112 and the ejection port 113X is provided between the brush electrode 112 and the ejection port 113X. Thereby, the same effect as that of the concave portion 114 can be achieved.

(Sixteenth embodiment)

In the tenth to fifteenth embodiments, the ion generating unit 110 or the brush electrode 112 is horizontally arranged, but it is not limited to this mode. In this embodiment, as shown in FIGS. 39 and 40, the ion generating unit 110 is vertically arranged below the installation space 113, and the brush electrodes 112 are arranged upward.

More specifically, for example, as shown in FIG. 39, a recessed portion 114B may be formed on the ejection port 113X side of the ion generating unit 110. In this way, if a recess 114B where a conductor stays is formed between the brush electrode 112 and the ejection port 113X, the possibility that the conductor moves outside the predetermined storage area can be reduced.

Alternatively, as shown in FIG. 40, a brush attachment portion 116 may be provided between the brush-shaped electrode 112 and the ejection port 113X. That is, if the conductor is detached from the brush electrode 112, the possibility of the conductor moving outside the predetermined storage area can be further reduced by the brush attachment portion 116.

Furthermore, as shown in FIG. 41, the ion generating unit 110 may be vertically arranged above the installation space 113, and the brush electrodes 112 may be arranged downward. In addition, as in the tenth embodiment, it is also possible to adopt a configuration in which the conductor falling off the brush electrode 112 falls into the recessed portion 114, or the brush passage prevention portion 115 or the twelfth embodiment may be adopted by the eleventh embodiment. The brush attachment portion 116 prevents the conductive body from moving outside the predetermined storage area.

(Seventeenth embodiment)

In order to reduce the possibility that the conductor detached from the brush electrode 112 moves outside the predetermined storage area, other configurations may be adopted. For example, as shown in FIG. 42, by making the ejection opening 113Y upward from the horizontal, the possibility that the conductor moves outside the predetermined storage area can be reduced.

In addition, the discharge port 113Y may be made of metal, and frost may be formed on the discharge port 113Y. The conductive body Z may fall into the recesses 114, 114B or the conductive body Z may not be easily removed by the water X on the wall surface or the water Y falling from the wall surface. The bottom surfaces of the recesses 114 and 114B are raised, thereby reducing the possibility of the conductive body Z moving outside the predetermined storage area.

(Eighteenth embodiment)

In addition, the brush electrode 112 is not limited to a configuration that is horizontally or vertically upward or downward, and may be disposed obliquely as shown in FIG. 43.
