Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a refrigerator capable of suppressing contamination of contents in a refrigerator by germs and mold.

[0002]

2. Description of the Related Art As is well known, a refrigerator is a container for storing food at a low temperature for a relatively long period of time. Unlike a freezer, the temperature in a refrigerator is usually about 4 ° C. For this reason, the interior of the refrigerator is often more contaminated with fungi than expected. In particular, vegetable storage rooms and the like are places that are easily contaminated because sometimes vegetables with soil are also contained.

[0003] Recently, with the growing awareness of hygiene or health, it is possible to store a refrigerator for a long period of time while maintaining a hygienic condition from a refrigerator that has merely focused on storage or storage as in the past. Emphasis is shifting to this point. In particular, contamination of foods or foods by fungi or mold is a serious problem for refrigerators.

[0004] For these reasons, recently, a refrigerator employing a method of continuously evaporating a volatile antibacterial agent in a refrigerator has been proposed. For example, Japanese Patent Application Laid-Open No. 9-53876 discloses that a container having a shape memory resin film is filled with a volatile antibacterial and fungicide, and that the gas permeability of the shape memory resin film depends on temperature. A technique for adjusting the volatile concentration of a fungicide / fungicide is disclosed. In Japanese Patent Application Laid-Open No. Hei 8-261633, a liquid holding material impregnated with a mixed liquid of an antioxidant such as dibutylhydroxytoluene and a volatile antibacterial agent such as isothiocyanate is stored in a freezer.
A technology is disclosed in which a volatile antibacterial agent is disposed in a refrigerator or a vegetable storage room at a ceiling portion so that a volatile antibacterial agent is continuously volatilized in the refrigerator to have an antibacterial effect.

[0005] However, in the method in which the volatile antibacterial agent is continuously volatilized in the storage, the antibacterial agent is consumed in a short time, and there is a problem that maintenance is troublesome. In addition, depending on the type of antibacterial agent, there may be a bad effect such as adding a smell peculiar to the antibacterial agent to food and components in the refrigerator,
Prolonged exposure of antimicrobial agents does not necessarily lead to good results.

[0006]

As described above, in the conventional refrigerator in which the antibacterial agent is continuously volatilized in the refrigerator, not only the consumption of the antibacterial agent is large but also the food and the parts in the refrigerator. Had the problem that the smell peculiar to the antibacterial agent was attached.

Accordingly, the present invention provides a refrigerator which can exhibit an antibacterial and antifungal function over a long period of time by using a small amount of an antibacterial agent, and can minimize the attachment of odor to foods and internal components. It is intended to provide.

[0008]

According to a first aspect of the present invention, there is provided a refrigerator comprising: a refrigerator main body; and a plurality of hermetically sealed bodies which seal a volatile substance having an antibacterial and antifungal effect. And an antibacterial substance pack that is housed in the refrigerator body and the sealing body is sequentially opened as time elapses.

According to another aspect of the present invention, there is provided a refrigerator according to a second aspect, wherein a refrigerator body and a volatile substance having an antibacterial and antifungal effect disposed in the refrigerator body are intermittently volatilized in the refrigerator. And an antibacterial substance releasing device.

In order to achieve the above object, in the refrigerator according to the third aspect of the present invention, the refrigerator main body and a liquid substance disposed in the refrigerator main body and having an antibacterial and antifungal effect are intermittently sprayed into the refrigerator. An antimicrobial substance releasing device is provided.

The antibacterial substance releasing device may be configured to perform volatilization or spraying when the cool air circulation fan of the refrigerator body is operated, or to store volatile substances by wind force when the cool air circulation fan is operated. The lid of the container may be opened to volatilize volatile substances.

Further, the antibacterial substance releasing device may be configured to volatilize or spray immediately after the door of the refrigerator main body or the drawer type door is closed in conjunction with the closing. In this case, volatilization or spraying may be performed using a force when the door of the refrigerator body or the drawer type door is closed.

Still further, the antibacterial substance releasing device may be arranged in the vegetable storage room of the refrigerator main body, and perform volatilization or spraying in conjunction with closing of the vegetable storage room door or the drawer type door. Good.

In the refrigerator according to the present invention, an antibacterial substance pack comprising a plurality of sealed bodies in which a volatile substance having an antibacterial and antifungal effect is sealed is housed in the refrigerator body, and the sealed bodies are stored over time. Are sequentially opened.

Therefore, in the refrigerator according to the first aspect,
By reducing the amount of volatile antibacterial substances sealed in one sealing body, it is as if the antibacterial substances are intermittently released into the chamber, and the consumption of antibacterial substances is reduced. The antibacterial and antifungal function can be exhibited over a long period of time. Further, since a large amount of the antibacterial agent is not volatilized at one time, it is possible to suppress the smell peculiar to the antibacterial agent from being attached to the food or the internal components.

The refrigerator according to the second and third aspects is provided with an antibacterial substance releasing device for intermittently volatilizing or spraying an antibacterial substance having an antibacterial and antifungal effect into the refrigerator. Therefore, in the refrigerator according to the second and third aspects, the consumption of the antibacterial substance can be significantly reduced as compared with a refrigerator in which the antibacterial substance is continuously volatilized or sprayed in the refrigerator, and the antibacterial protection that is stable over a long period of time. A mold function can be exhibited. Further, since a large amount of antibacterial agent is not used at one time, it is possible to suppress the smell peculiar to the antibacterial agent from being attached to foods and components in the refrigerator.

In this case, by adopting a configuration in which the antibacterial substance is volatilized or sprayed when the cool air circulation fan of the refrigerator body is operated, the antibacterial substance can be spread to each part in a short time by being put on the circulating airflow. In addition, by adopting a configuration in which the lid of the container containing the antibacterial substance is opened by the wind force when the cool air circulation fan is operated and the antibacterial substance is volatilized, the antibacterial substance can be spread to each part in a short time by placing it in the circulating airflow The antimicrobial substance releasing device can be operated without external power.

Further, if a construction is adopted in which the antibacterial substance is volatilized or sprayed immediately after the door of the refrigerator body or the pull-out door is closed in conjunction with the closing, the bacteria invading from the outside propagate in the refrigerator. Since the antibacterial substance can act on the previous time point, the bacteria can be effectively sterilized. In this case, if a configuration is adopted in which the antibacterial substance is volatilized or sprayed by using a force when the door of the refrigerator body or the drawer type door is closed, the antibacterial substance release device can be operated without applying external power. it can.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example in which the present invention is applied to a refrigerator according to a first embodiment of the present invention, here, an electric refrigerator-freezer used in homes and the like.

In FIG. 1, reference numeral 1 denotes a refrigerator-freezer main body. The refrigerator-freezer main body 1 includes a refrigerator compartment 2, a freezer compartment 3, and a vegetable storage compartment 4. A single door 5 is provided at the opening of the refrigerator compartment 2, and drawer doors 6, 7, 8 are provided at the openings of the freezing compartment 3 and the vegetable storage compartment 4.

In this refrigerator-freezer body 1, cold air is generated as follows. First, after the refrigerant compressed by the compressor 9 is condensed by a condenser (not shown), the condensed liquid is evaporated in the evaporator 10, and the heat of evaporation evaporates the evaporator 10.
To cool. Then, an airflow is generated by a fan 11 for circulating cool air, and the airflow obtained by bringing the airflow into contact with the evaporator 10 is distributed and introduced into the refrigerator compartment 2, the freezer compartment 3 and the vegetable storage compartment 4.

A support shelf 12 having an L-shaped cross section as shown in FIG. 2 is provided on the ceiling of the freezing compartment 3 located on the lower side near the front of the fan 11 for sending cool air into the refrigerator. It is provided so as to protrude. The antibacterial substance pack 13 is selectively placed on the upper surface of the support shelf 12.

As shown in FIG. 2, the antibacterial substance pack 13 includes a plastic container 15 having, for example, five small chambers 14 and a volatile antibacterial agent 16 contained in each of the small chambers 14 and having an antibacterial and antifungal effect. And an aluminum foil laminated resin film 17 that seals the opening of the container 15.

In this case, the antibacterial agent 16 is allyl isothionate (3 wt% based on ethyl alcohol) obtained by extracting ethyl alcohol and wasabi as a gelling agent.
% Mixed) and gelled. The reason for the gelation is to prevent the liquid from spilling when the plastic container 15 containing the antibacterial agent 16 is placed on or removed from the support shelf 12, and to delay the evaporation of the liquid to extend the life. There is to plan. In addition, five small rooms 14
Each small room 1 has an aluminum foil laminated resin film 17 attached to a plastic container 15 so as to seal
A cut 18 is provided so that every four can be opened independently.

In order to provide an antibacterial and antifungal function to the refrigerator having the above-described structure, the following is performed. First, the aluminum foil laminated resin film 17 in the small compartment 14 of the antibacterial substance pack 13 is peeled off. Film 1
7 is peeled off, the ethyl alcohol and allyl isothionate volatilize.
Riding on the air flow sent out from 1 and flowing to each part, it adheres to the surface of the contents in the refrigerator and exhibits an antibacterial and antifungal function.

If the antimicrobial agent 16 is used for a while in this state, the antimicrobial agent 16 is eventually volatilized and consumed, so that the antimicrobial and antifungal effect in the refrigerator becomes weak. Then, the aluminum foil laminated resin film 17 of the next small room 14 is newly peeled off, and the ethyl alcohol and allyl isothionate are vaporized again. By repeating this as shown in FIG. 3, it becomes possible to fill the inside of the refrigerator with a required level of antibacterial and antifungal gas over a long period of time.

As described above, in the refrigerator according to this example, it is as if the antibacterial agent 16 is intermittently released into the refrigerator, and the consumption of the antibacterial agent 16 is suppressed for a long period of time. An antibacterial and antifungal function can be exhibited. Further, since a large amount of the antibacterial agent 16 is not volatilized at one time, it is possible to suppress the smell peculiar to the antibacterial agent from attaching to the food and the parts in the refrigerator.

Although the antibacterial substance pack 13 having five small rooms 14 is used in the above-described example, the number of the small rooms 14 is not limited to the above value. FIG. 4 shows an example in which the present invention is applied to a refrigerator according to a second embodiment of the present invention, and also to an electric refrigerator-freezer used in homes and the like.

In this figure, the same reference numerals are given to the same functional parts as in FIG. Therefore, a detailed description of the overlapping part will be omitted. This example differs from the previous example in that an antibacterial substance releasing device 22 is attached to the inner surface of the inner wall of the container 21 arranged in the vegetable storage chamber 4.

As shown in FIG. 5, the antibacterial substance releasing device 22 includes a container 24 containing a volatile antibacterial agent 23 having an antibacterial and antifungal effect, and a container 24 having one end rotatably supported by the container 24. A lid 25 for selectively closing the upper opening portion 24
And a plunger 26 for applying a release force to the lid 25,
The plunger 26 includes a timer driving mechanism (not shown) for urging the plunger 26 at regular intervals and for a fixed period to release the lid 25, and a battery (not shown) as a power supply.

As the antibacterial agent 23, allyl isothionate obtained by extracting horseradish in ethyl alcohol is 3w
What dissolved t% is used. With such a configuration, the plunger 26 is urged at regular intervals for a fixed time. Therefore, while the plunger 26 is being urged, the lid 25 rotates as shown by a two-dot chain line in FIG. 5 to release the upper opening of the container 24. As a result, the antimicrobial agent gas floating in the upper space of the container 24 flows into the container 21 and adheres to the surface of the container in the container 21 to exhibit an antibacterial and antifungal function. Thereafter, the above-described operation is performed intermittently.

As described above, the antibacterial substance releasing device 22 for intermittently volatilizing the gas of the antibacterial agent 23 having the antibacterial and antifungal effect is provided in the storage. Therefore, the consumption of the antibacterial agent 23 can be significantly reduced as compared with the case where the antibacterial agent 23 is continuously volatilized in the storage, and a stable antibacterial and antifungal function can be exhibited over a long period of time. In addition, since a large amount of the antibacterial agent 23 is not used at a time, it is possible to suppress the smell peculiar to the antibacterial agent from being attached to the food or the internal components.

Table 1 shows the actual measurement and calculation results of the consumption rate of the antibacterial agent, the theoretical retention period of the antibacterial agent, the antibacterial effect, and the evaluation of the odor transfer, together with the conventional example (continuous volatilization) based on the frequency of volatilization. I have.

[0034]

[Table 1]

As can be seen from Table 1, when the antibacterial agent is volatilized 10 times a day for 1 minute, an antibacterial effect equivalent to that of the conventional example in which the antibacterial agent is continuously volatilized can be obtained. In addition, the consumption of the antimicrobial agent can be reduced by about 180 times. In addition, the smell can be prevented from being transferred to the contents. This result also shows that it is effective to intermittently volatilize the antibacterial agent.

FIG. 6 shows an example in which the present invention is applied to a refrigerator according to a third embodiment of the present invention, and also to an electric refrigerator-freezer used in homes and the like. In this figure, the same reference numerals are given to the same functional parts as those in FIG.
Therefore, a detailed description of the overlapping part will be omitted.

This example is different from the example shown in FIG. 4 in that the antibacterial substance releasing device 30 is mounted on the inner surface of the inner wall of the container 21 arranged in the vegetable accommodating chamber 4, and the container 21 is inserted to the back. That is, the antibacterial substance releasing device 30 is operated for a certain period of time in synchronization with the closing of the door 8.

As shown in FIG. 7, the antibacterial substance releasing device 30 includes a container 32 containing a liquid antibacterial agent 31 exhibiting an antibacterial and antifungal effect, and sucks up the antibacterial agent 31 in a spraying manner into the container 21. A pump 33 for spraying, a switch 34 which is turned on when the container 21 is inserted into the depth of the vegetable storage chamber 4 and hits the inner wall of the vegetable storage chamber 4; In this example, a pump drive circuit (not shown) for operating the pump 33 for only 5 seconds and a battery (not shown) serving as a power supply are provided.

As the antibacterial agent 31, allyl isothionate obtained by extracting horseradish in ethyl alcohol is 3w
What dissolved t% is used. In the refrigerator configured as described above, when the door 8 of the vegetable storage chamber 4 is closed, the switch 34 is turned on, and the pump 33 is operated to eject air for 5 seconds.
The antibacterial agent 31 in 2 is sprayed to exhibit an antibacterial and antifungal function. The above operation is performed every time the door 8 of the vegetable storage room 4 is closed.

The spraying time varies depending on the amount of stored vegetables and the type of the stored items (for example, a beer bottle may be put in the container). Further, when the spraying of the antibacterial agent 31 is repeated, the antibacterial agent 31 in the container 32 is consumed and finally disappears.
In this case, replenishment is performed through a liquid replenishment port (not shown).

As described above, the antibacterial substance releasing device 30 for intermittently spraying the antibacterial agent 31 having the antibacterial and antifungal effect into the refrigerator.
Is provided. Therefore, compared to continuously volatilizing or spraying the antibacterial agent 31 into the refrigerator, the consumption of the antibacterial agent 31 can be significantly reduced, and a stable antibacterial and antifungal function can be exhibited over a long period of time. . Further, since a large amount of the antibacterial agent 31 is not used at one time, it is possible to suppress the smell peculiar to the antibacterial agent from being attached to the food or the internal components.

The results shown in Table 2 were obtained by comparing the number of general bacteria adhering to vegetables in the case where the antibacterial agent 31 was sprayed in this way and in the case where no ordinary operation was performed. From this result, it can be seen that bacteria are greatly reduced by spraying and can be stored extremely hygienically.

[0043]

[Table 2]

In this example, the antibacterial agent 31 is sprayed for a certain time immediately after closing the door 8 of the vegetable accommodating chamber 4, and at such a spray timing, bacteria invading from the outside propagate in the refrigerator. Since the antibacterial agent 31 can act at a time before the treatment, the bacteria can be effectively sterilized. That is, Table 3 shows that the antibacterial agent 31 is sprayed immediately after the door 8 of the vegetable storage room 4 is closed, and that the antimicrobial agent 31 is sprayed at the time of 12 hours after the door 8 of the vegetable storage room 4 is closed. The results of examining the sterilization rate in the case of performing the test are shown.

[0045]

[Table 3]

As is clear from Table 3, when the antibacterial agent 31 is sprayed immediately after the door 8 is closed, the sterilization rate is higher than when sprayed 12 hours later, and the antibacterial effect is excellent.
It is considered that this is because if the spraying time is delayed, bacteria grow in the vegetable storage room 4 to some extent. Therefore, it is appropriate to spray the antibacterial agent 31 immediately after the door is closed.

In the above-described example, the door or door closing is detected by the operation of the switch 34, and the pump 33 is operated for a certain period of time to spray the antibacterial agent 31, but the pump is not used. Alternatively, air may be ejected by operating a piston with the force when the door is closed, and the antibacterial agent may be sprayed using the air by a normal spraying principle.

FIG. 8 shows an antibacterial substance releasing device 40 in which the antibacterial agent 31 is sprayed according to the above-described principle.
In this figure, the same functional parts as those in FIG. 7 are indicated by the same reference numerals.

The antibacterial substance releasing device 40 includes a container 32 containing a liquid antibacterial agent 31 exhibiting an antibacterial and antifungal effect.
And a cylinder 41, a piston 42 that abuts against the inner wall of the vegetable storage chamber 4 when the container 21 is inserted to the depth of the vegetable storage chamber 4 and compresses the air with the cylinder 41, and blows out the compressed air. Antibacterial agent 31 in the usual spraying manner
It comprises a jet port 43 for sucking up and spraying, a spring 44 for giving a restoring force to the piston 42, and a check valve 45 provided on the piston 42 and closed when compressed and opened when returning.

In this example, as the antibacterial agent 31, 3 wt% of allyl isothionate obtained by extracting from wasabi in ethyl alcohol is used. With such a configuration, when the door of the vegetable storage chamber is closed, the piston 42 collides with the inner surface of the inner wall of the vegetable storage chamber, and is pushed to move in the cylinder 41. As a result, the air in the cylinder 41 is compressed and spouts vigorously from the spout 43. As a result, the container 32 is formed by the usual spraying principle.
The antibacterial agent 31 inside is sucked up and atomized and sprayed into the vegetable storage chamber.

With such a structure, the same effect as in the above example can be expected, and spraying can be performed without using power such as an electric pump, so that energy can be saved and a structure that does not easily break down can be achieved.

FIG. 9 shows an example in which the present invention is applied to a refrigerator according to a fourth embodiment of the present invention, and also to an electric refrigerator-freezer used in homes and the like. In this figure, the same reference numerals are given to the same functional parts as those in FIG.
Therefore, a detailed description of the overlapping part will be omitted.

The refrigerating refrigerator according to this embodiment differs from that shown in FIG. 1 in that an antibacterial substance is formed near the front surface of a fan 11 for circulating cool air, in this example, on a support shelf 12 as shown in FIG. The release device 22 or the antibacterial substance release device 30 configured as shown in FIG. 7 (excluding the switch 34) is disposed, and each time the fan 11 is operated (starts rotation), the plunger 26 or the pump is operated for 5 seconds, for example. 33
Is driving.

With such a configuration, the same effect as in each of the above-described examples can be expected, and the antibacterial substance can be spread to each part in a short time by being put on the circulating airflow generated by the fan 11. That is, when the diffusion rate of the evaporated or sprayed antibacterial substance was evaluated, it took 5 to 7 minutes for the antibacterial substance to reach the uppermost shelf in the refrigerator when not linked to the fan 11, but the fan 11 It was confirmed that the diffusion reached within seconds when linked with. The gas concentration was measured by gas chromatography.

As described above, when the antimicrobial substance is volatilized or sprayed intermittently in synchronism with the start of rotation of the fan 11 in conjunction with the fan 11, the antimicrobial substance gas is diffused very quickly and uniformly in the chamber. Therefore, an antibacterial and antifungal effect can be imparted uniformly and promptly.

In the above example, the antibacterial substance is volatilized or sprayed by operating the plunger or the pump in synchronization with the start of rotation of the fan 11. An antibacterial substance releasing device may be provided in which the lid of the container containing the antibacterial agent is opened to thereby volatilize and release the antibacterial agent.

FIG. 10A shows an antibacterial substance releasing device 50 that performs the above-described functions. This antibacterial substance releasing device 50 includes a container 52 containing a volatile antibacterial agent 51.
And an intermediate portion 53 is rotatably supported by an edge of the container 52, and one side is provided with a lid 53 that selectively closes an upper opening of the container 52 with the intermediate portion 53 as a boundary, and the other side is a fan 11. A plate member 56 provided on a wind receiving plate 55 that applies a rotating force to the cover 53 with the intermediate portion 53 as a fulcrum in response to the wind sent from the container 53, and a force for closing the upper opening of the container 52 with the cover 54. And a spring 57 that constantly applies the pressure to the plate member 56.

The antibacterial substance releasing device 5 configured as described above
0 is disposed near the front surface of the fan 11 and used.
In the antibacterial substance releasing device 50 having the above configuration, when the wind 58 hits the wind receiving plate 55 with the rotation of the fan 11, as shown in FIG. Rotate in the direction of rotation. As a result, the lid 54 separates from the container 52, and the antibacterial agent 51 inside volatilizes.

In this manner, when the lid is opened by the wind of the fan 11 to intermittently volatilize the antibacterial agent therein, the same effect as in the previous example can be exerted and energy can be saved. There is an advantage that failure can be reduced because the structure is simple and the structure is simple.

Each of the above-mentioned examples is an example in which the present invention is applied to a refrigerator for home use, but it is needless to say that the present invention can be applied to refrigerators in general. Further, the type of the antibacterial agent is not limited to the above example.

[0061]

As described above, according to the present invention, an antibacterial and antifungal function can be exerted for a long period of time while suppressing the consumption of the antibacterial agent. Can be prevented from adhering.
