[Patent Document 1]
JP 2002-95731 A (paragraphs 0013 to 0016, FIG. 1)
[0004]
[Problems to be solved by the invention]
By the way, in patent document 1, the floating microbe which floats in the cold inside of a store | warehouse | chamber is a sterilization object, and the floating microbe which invaded in the store from the living space outside the store | warehouse | chamber is alone or in the state where it adhered to the particle It is necessary to float at least.
[0005]
However, as a result of investigating the inside of a refrigerator equipped with an ion generator that is actually used, a large number of airborne bacteria have been detected, and some of the airborne bacteria that have entered the interior float in the cold air. It was confirmed that the molded product remained in the cabinet due to the charging effect of the molded product.
[0006]
It is conceivable that some of the airborne bacteria that are charged and adhered to the molded product enter the interior from the living space outside the refrigerator where the refrigerator is installed as the airborne bacteria and remain in the interior. Therefore, even if the interior is sterilized, floating bacteria enter when the door is opened.
[0007]
Therefore, an air purifier with the same function may be installed in the living space where the refrigerator is installed to eliminate the invasion of airborne bacteria from the outside of the warehouse, but it is judged from recent housing circumstances. Then, it cannot be said that it is a general solution for reasons such as taking a place of installation.
[0008]
Then, this invention aims at providing the refrigerator which can solve the said subject, implement | achieves a hygienic surrounding living environment, and can exclude the invasion | floating of the floating microbe into the store | warehouse | chamber.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, ionized air containing positive ions and negative ions is released to the living space outside the warehouse, in particular, the front surface outside the storage room where floating bacteria such as bacteria and viruses enter, By suppressing and removing the proliferation of planktonic bacteria that exist in the living space, planktonic bacteria that enter the cabinet from the outside without taking up space are eliminated. Therefore, a more sanitary inside / outside environment can be realized.
[0010]
That is, in the refrigerator according to the present invention, an ion generator that generates positive ions and negative ions is provided on the ceiling, and positive ions are generated from the ion generator into a living space outside the refrigerator, particularly a living space in front of the refrigerator body. It is characterized by the release of negative ions.
[0011]
According to the above configuration, by releasing positive ions and negative ions to the living space outside the refrigerator body, the floating bacteria present in the living space are sterilized to realize a sanitary living space, and at the same time the door Eliminate airborne bacteria that enter from inside to outside during opening and closing. As a result, a sanitary internal environment can also be realized.
[0012]
In this invention, by providing an ion generator in the ceiling part of a refrigerator main body, the ionized air containing the positive ion produced | generated by the ion generator and negative ion can be blown out from a high position. Therefore, since ions can be diffused over a wide range, the sterilizing effect of floating bacteria outside the warehouse can be amplified.
[0013]
In addition to the above configuration, a dedicated blower may be provided to expand the existence area of the released positive ions and negative ions. By blowing the ion generator at a sufficient air flow rate, the ion existence area outside the chamber is expanded several times to several tens of times compared to the case without air blowing, and ionized air is released to a wider living space. be able to. In particular, when the creeping discharge method is used, the electric field is difficult to spread three-dimensionally with respect to the creeping surface. Therefore, unlike the space discharge type having no ground electrode, providing a blower is a very effective means.
[0014]
Furthermore, in the present invention, by providing the ion generator on the ceiling of the refrigerator body, in the refrigerator without the ion generator, the ion generator can be easily provided only by changing the design of the ceiling. In addition, the interior and door can be manufactured without changing the design, contributing to cost reduction.
[0015]
About the arrangement | positioning of an ion generator, if the position can discharge | release ion to the living space ahead of the ceiling part of a refrigerator main body, the installation location will not be limited. For example, since an attachment member for attaching the hinge for the door of the uppermost warehouse is projected on the front surface of the ceiling portion, an ion generator is formed using a space formed in front of the ceiling portion by the attachment member Can be arranged. In addition, as a mounting member, a mounting plate for mounting the hinge of the door of the storage room is provided on the ceiling, and in the case of a refrigerator in which this mounting plate is covered with a cover, the space formed inside this cover is used. And an ion generator is arrange | positioned in a cover, and, thereby, a space can be utilized effectively. In particular, in the case of a double-sided door, the hinge mounting plates are located on both the left and right sides, so that the ion generator can be arranged using the space formed between the left and right hinge mounting portions. Moreover, when covering the whole attachment part of a right-and-left hinge with a cover, an ion generator can be arrange | positioned in the space between the attachment part of the hinge, and a cover.
[0016]
And an inlet is formed in the lower surface of a cover, and a blower outlet is formed in the front of a cover. Therefore, since all the doors are located below the outlets, it is possible to effectively eliminate floating bacteria that try to enter the warehouse.
[0017]
A recess is formed in a part of the lower surface of the cover facing the uppermost door, and an inlet is formed in the recess. This recess widens the gap with the door, so that even when the door is closed, sufficient air can be sucked from the suction port.
[0018]
Furthermore, by blowing out ionized air in one direction, it is possible to effectively blow out ionized air into each door or the living space in front of the refrigerator body. Therefore, it is not necessary to provide a louver that changes the directivity in the blowing direction.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a refrigerator showing an embodiment of the present invention, FIG. 2 is a top view of the refrigerator, FIG. 3 is a diagram showing an internal structure of a ceiling portion provided with an ion generator, and FIG. A sectional view and FIG. 5 are BB sectional views of FIG.
[0020]
As shown in FIG. 1, the refrigerator in this embodiment is provided with a refrigeration room in the upper part of the refrigerator main body 11, and a freezer room and a vegetable room are arranged thereunder, and these are partitioned by a heat insulating partition. The refrigerator compartment can be opened and closed by a door 12 pivotally supported on the front surface. Similarly, the freezer compartment and the vegetable compartment can be opened and closed by the doors 12 pivoted on the front surface. The door 12 is supported by the hinge so as to be opened and closed. In addition, in the refrigerator of this embodiment, there are hinges on the left and right sides, and the left and right can be opened.
[0021]
As shown in FIGS. 2-4, the ceiling part 13 of the refrigerator main body 11 is comprised by the top | upper surface part 13a and the front side part 13b, and is made flush | level. The front portion 13b is formed by a support member 15 that holds the attachment plate 14 to which the hinge is attached, and a cover 16 that covers the upper portion of the support member 15 in order to hide the attachment plate 14.
[0022]
The hinge mounting plate 14 having hinges on both sides is formed so that the left and right sides protrude forward, and the central portion of the hinge mounting plate 14 is recessed. An ion generator 17 is disposed in the central portion. Next to the ion generator 17, a substrate holding member 18 having an operation substrate 19 standing is disposed. The operation board 19 is a circuit board for operating the ion generator 17.
[0023]
The ion generator 17 includes a case 20 formed of a resin molded product, a discharge electrode unit that generates positive ions and negative ions, and an ion generation unit 21 that includes a drive circuit that supplies a voltage to the discharge electrode unit. It comprises a blower 22 for blowing out and is unitized. The case 20 is attached to the support member 15 with screws or the like, and an ion generator 21 and a blower 22 are mounted inside the cylindrical case 20. A suction port 24 for taking in air is formed on the lower surface of the case 20, and an air outlet 25 for blowing ionized air is formed on the side surface, and an air passage 23 extending from the suction port 24 to the air outlet 25 is formed.
[0024]
A dustproof filter 26 is attached to the suction port 24. The dust filter 26 removes dust in the air sucked from the suction port 24, and suppresses performance degradation due to dust adhesion on the discharge electrode portion of the ion generator 21. Further, a centrifugal blower 22 composed of a multiblade fan having a narrow blade width is disposed above the suction port 24. The blower 22 blows air in the horizontal direction so that the air sucked from the suction port 24 passes over the ion generator 21.
[0025]
The wall surface of the case 20 facing the air passage 23 is covered with a conductor such as aluminum tape. The case 20 that is a resin molded product is easily charged, and ions may adhere to the wall surface. By imparting conductivity to the wall surface of the case 20, the adhesion of ions to the wall surface can be suppressed, and the disappearance of ions in the air blowing path 23 can be reduced. Therefore, a sufficient amount of ions blown out from the blowout port 25 can be secured.
[0026]
As shown in FIG. 1, a display unit 27 that monitors and displays the operation state of the ion generator 17 is provided on the left side of the support member 15, and an operation for operating the ion generator 17 is provided on the right side. A portion 28 is provided. In the center, an opening for blowing ionized air is formed facing the outlet 25. Furthermore, as shown in FIGS. 4 and 5, the lower surface of the support member 15 faces the door 12 of the refrigerator compartment, and a recess 29 is formed at the center. An opening is formed in the recess 29 so as to face the suction port 24 of the ion generator 17 in order to suck air outside the chamber. The recess 29 widens the gap with the door 12, so that sufficient air can be sucked from the suction port 24 even when the door 12 is closed. In addition, 29 in FIG. 4, FIG. 5 is a gasket.
[0027]
Next, the operation of generating ions with the above configuration will be described. The ion generator 17 is energized by turning on the operation unit 28. The ion generator 17 and the blower 22 operate at the same time, and air outside the refrigerator is sucked into the case 20 from the suction port 24. The sucked air passes through the dust filter 26 and flows through the air passage 23. The positive ions and negative ions generated from the ion generator 21 ride on the passing wind and become ionized air. This ionized air is blown out from the outlet 25.
[0028]
Since the blower outlet 25 is provided in the ceiling part 13, the ionized air blown out of the warehouse reaches far and diffuses over a wide range. With the positive ions and the negative ions, the floating bacteria existing in the living space are sterilized, and the floating bacteria existing in the vicinity of the refrigerator main body 11 are reduced. Thus, the front of the refrigerator main body 11 is blocked by ionized air, and becomes a living space with few floating bacteria. When the door 12 is opened and closed, the floating bacteria that enter from the outside to the inside are removed. Therefore, a more sanitary inside and outside environment can be realized.
[0029]
Moreover, if the blowing direction of the blower outlet 25 is directed downward, a curtain of ionized air can be formed in front of the refrigerator main body 11. With this air curtain, the invasion path of airborne bacteria approaching the refrigerator main body 11 can be blocked, and airborne bacteria that invade into the cabinet can be eliminated more reliably.
[0030]
In addition, this invention is not limited to the said embodiment, A correction and a change can be added within the scope of the present invention. For example, you may arrange | position an ion generator on the upper surface of a ceiling part. Furthermore, you may provide the ion generator for external use and internal use. Further, the present invention can be applied not only to the both-side opening / closing doors as in the above embodiment but also to the one-side opening / closing doors. That is, when a hinge mounting plate for attaching a hinge on one side is employed, the ion generator can be disposed in a space in front of the ceiling portion formed on the side of the mounting plate protruding forward.
[0031]
【The invention's effect】
As described above, according to the present invention, by providing the ion generator on the ceiling of the refrigerator main body, the floating bacteria in the living space outside the warehouse can be eliminated by an excellent sterilization effect. It becomes a hygienic and comfortable living space, and it is possible to eliminate airborne bacteria that enter the inside from the outside as the number of airborne bacteria decreases. Moreover, since the blower outlet is provided in the ceiling part, there is no danger of being tricked by an infant.
[0032]
Furthermore, it is not necessary to secure a new installation space by using the space existing in the ceiling. Therefore, it is possible to easily mount the ion generator without a large design change, and it is possible to divert without changing the interior or the door portion, thereby reducing the cost.
