  The present invention relates to a decomposing apparatus having a function of decomposing residual pesticides adhering to the surface of food, and a refrigerator provided with the decomposing apparatus.

  With the increasing awareness of food safety, there is increasing interest in devices having the function of decomposing residual pesticides adhering to the surface of foods such as vegetables. In order to cope with this, there has been proposed a refrigerator having a function of promoting the removal of pesticide residues adhering to the surface of the food stored in the heat retention case using ozone generated by the ozone generator (for example, a patent) Reference 1).

JP, 2010-54092, A

In the refrigerator described in Patent Document 1, the agrochemicals adhering to the surface of the food can be decomposed using the oxidizing power of ozone generated by the ozone generator. However, the ability of ozone to decompose pesticides is naturally limited, and there is a possibility that residual pesticides adhering to the surface of food can not be decomposed sufficiently.
In addition, since the lid hole for allowing the gas containing ozone to flow into the heat retention case is disposed only on the rear surface side of the heat retention case, sufficient ozone does not spread to the food stored in the area other than the rear surface side of the heat retention case. As a result, it may be unreliable in the decomposition ability of the pesticide residue.

Water droplets can be prevented from adhering to the inner wall forming the second region.

Further, in the present invention, a container capable of taking in and out from the outside is disposed in the second area;
It is characterized by having a mechanism by which pushing is regulated when the container is pushed into the second area in a state where the stored food or lid is lifted above the upper surface of the container.

In FIGS. 1 and 3, the flow of gas is schematically shown by a broken arrow.

(Decomposition device in one embodiment of the present invention)
FIG. 1 is a perspective view schematically showing a disassembling apparatus 2 according to an embodiment of the present invention. In this embodiment, the case where the decomposition apparatus 2 is arrange | positioned in the refrigerator of a refrigerator is shown. (A) shows a closed state in which the pullout type container 40 is closed, and (b) shows a released state in which the pullout type container 40 is drawn forward. FIG. 2 is an exploded perspective view showing members constituting the first area 4 of the disassembling apparatus 2 shown in FIG.
First, the disassembling apparatus 2 according to one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  The disassembling apparatus 2 according to the present embodiment has a first area 4 having at least a header area 8 and a second area 6 that functions as a food storage area disposed below the first area 4. In the present embodiment, the first area 4 is configured by the header area 8 and the flow path 22 arranged side by side. The first area 4 and the second area 6 arranged above and below are separated by a partition plate 10. In the partition plate 10, a plurality of through holes 12 are provided, and the gas in the header area 8 of the first area 4 passes through the through holes 12 (see arrow A). It is supposed to flow in.

  Describing the structure of the disassembling device 2 in more detail, the first region 4 includes the partition plate 10, an outer wall 14A surrounding the periphery of the partition plate 10, and a side wall 14B dividing the header region 8 and the flow passage 22. It is comprised by the ceiling member 16 which covers the upper part of the housing | casing 14 integrally formed, and the housing | casing 14 (refer FIG. 2). In the present embodiment, a housing 14 defining the first area 4 is fixed to the inner wall of the refrigerator. The housing 14 can be attached to the inner wall of the refrigerator directly by attaching the housing 14 directly to the inner wall, or via the rails 50 and the stay 52 described later.

  A rail 50 is attached via the stay 52 at a position below the housing 14 on the inner wall of the refrigerator, and the drawer-type container 40 is movably mounted on the rail 50. The container 40 functions as a food storage area, and the upper surface of the container 40 is in close contact with the lower surface of the partition plate 10 in the closed state where the container 40 is closed as shown in (a). Therefore, the area shielded from the outside surrounded by the container 40 and the partition plate 10 corresponds to the second area 6 which functions as a food storage area.

The user can switch from the closed state to the open state where food can be put in and out as shown in (b) by opening the door of the refrigerator and pulling the container 40 forward.
Although a resin material can be illustrated as a material of the housing | casing 14, the ceiling member 16, and the container 40, it is not restricted to this, Arbitrary other materials, such as a metal material, can be employ | adopted.

<Close mechanism of pull-out type container>
Guides 42 are provided on the left and right sides of the container 40, and claw members 44A and 44B are provided on the left and right sides of the housing 14. The claw-like members 44A and 44B are each formed of a plate-like vertical portion which descends downward from the housing 14 and a plate-like horizontal portion which is bent inward at a lower portion of the vertical portion. In the closed state in which the container 40 is closed as shown in (a), the lower surface of the guide 42 abuts on the upper surface of the horizontal portion of the claw members 44A and 44B, and both are fitted. The upper surface of the cover closely contacts the lower surface of the partition plate 10 which is the lower surface of the housing 14.

The height dimension of the vertical portion of the front claw 44A is larger than the height dimension of the vertical portion of the rear claw 44B. Corresponding to this, the height dimension of the guide 42 on the container 40 side is also larger than the dimension corresponding to the rear claw member 44B at the position corresponding to the front claw member 44A. . The guide 42 is appropriately sloped so that the guide 42 of the container 40 and the claw members 44A and 44B of the housing 14 smoothly fit when the container 40 is pushed from the release position to the closed position. .
In FIG. 5 showing the side surface and cross section taken along the line A-A in FIG. 1, in the case (a) where the container 40 is in the closed position, the lower surface of the guide 42 abuts against the upper surface of the plate-like horizontal portion 44A1. In the case where the container 40 is at the release position (b), the lower surface of the guide 42 and the upper surface of the plate-like horizontal portion 44A1 are separated.

  According to the above configuration, the food is put in the container 40 too much, and the food sticks out from the upper surface of the container 40, or when the container 40 has a lid, the food is put in the container 40 too much, With the lid raised from the container 40, a closure mechanism can be configured where the pushing is restricted when the container 40 is pushed into the closed position. By the above mechanism, the inside of the container 40 is sealed, and safe and effective decomposition of the pesticide can be implemented.

  Returning to the description of the first area 4 defined by the upper housing 14 and the ceiling member 16, the header area 8 has a substantially rectangular planar shape in plan view, and the flow path 22 has a substantially rectangular header area It is arrange | positioned in the substantially L-shape on the outer side of 2 of 8 sides. Therefore, the first area 4 constituted by the header area 8 and the flow path 22 also has a substantially rectangular planar shape in a plan view, whereby the partition plate which divides the first area 4 and the second area 6 10 also have a substantially rectangular planar shape in plan view.

  A fan 24 communicating with the lower second area 6 is disposed on the inlet side of the L-shaped flow path 22. Furthermore, the discharge device 30 is disposed at a position relatively close to the outlet side of the flow passage 22, and the ozone decomposition filter 26 </ b> A in communication with the header region 8 is disposed at the outlet side of the flow passage 22. As described above, the decomposing device 2 according to the present embodiment includes the gas supply unit 20 having the flow path 22, the fan 24, the discharge device 30, and the ozone decomposition filter 26A.

  In addition to this, a further ozonolysis filter 26B is disposed between the fan 24 and the discharge device 30 in the flow path 22. Further, in the header area 8 of the first area 4, the humidity control filter 28 is disposed. Furthermore, on the rear side of the decomposition apparatus 2, an automatic valve 60 capable of releasing the gas in the flow path 22 to the outside is disposed. The additional ozonolysis filter 26B, the humidity control filter 28 and the automatic valve 60 will be described in detail later.

  The suction port of the fan 24 opens into the second area 6 and discharges the sucked gas in the second area 6 into the flow path 22 in the horizontal direction. An axial fan may be used as the fan 24 or a sirocco fan may be used.

  In the discharge device 30, the high voltage generated by the high voltage generator 38 is applied to the electrode provided in the discharge portion 32 to cause discharge. This discharge can generate ozone and ions. As an output voltage of the discharge device 30, 1 KV to 20 KV can be illustrated. The detailed structure of the discharge device 30 according to the present embodiment will be described in detail later.

  As the ozonolysis filter 26A, for example, a catalyst filter in which a catalyst is supported on a honeycomb carrier can be used. The ozone generated by the discharge of the discharge device 30 passes through the ozonolysis filter 26A, whereby the ozone is decomposed to generate a gas containing a superoxide anion. The superoxide anion is a type of active oxygen in which oxygen molecules contained in the atmosphere are converted to a more reactive compound, and has a higher pesticide decomposition ability than ozone.

  With the above configuration, the gas sucked from the second area 6 by the fan 24 flows in the flow path 22, passes through the discharge device 30 and the ozone decomposition filter 26A, and flows into the header area 8. A flow cycle which flows from the header area 8 to the second area 6 is formed through the plurality of through holes 12 provided in the partition plate 10 (see the broken arrow in FIG. 1).

  In the decomposition apparatus 2 according to the present embodiment, ozone generated by the discharge of the discharge device 30 is decomposed by the ozonolysis filter 26A disposed on the outlet side of the flow path 22 to generate a gas containing superoxide anion. The gas containing the superoxide anion (specifically, the gas containing superoxide anion, ozone and ions) is passed through the plurality of through holes 12 provided in the partition plate 10 to form the header region 8 of the first region 4. By flowing into the second region 6, it is possible to decompose the residual pesticide attached to the surface of the food stored in the second region 6. In the present embodiment, decomposition of the residual pesticide by ozone + ion is performed instead of ozone alone, and further decomposition of the residual pesticide to which the superoxide anion is added can be realized. In particular, the superoxide anion is likely to disappear after generation due to its high reactivity, but in the present embodiment, since the ozonolysis filter 26A is disposed on the outlet side of the flow path 22, more superoxide is removed. Anions can be fed into the second zone 6 to more effectively degrade residual pesticides. Furthermore, the plurality of through holes 12 provided in the header region 8 and the partition plate 10 allow the gas containing the superoxide anion that has passed through the ozonolysis filter 26A to flow uniformly into the second region 6, The reliability of the decomposition of the residual pesticide can be improved.

As described above, in the present embodiment, it is possible to provide a highly reliable decomposing apparatus 2 capable of effectively decomposing the residual pesticide adhering to the surface of the stored food.
In particular, the food stored at an arbitrary position in the second area 6 by providing a plurality of through holes 12 above the entire area of the second area 6 except the lower side of the flow path 22 in plan view Can reliably break down residual pesticides adhering to the surface.

In this embodiment, the partition plate 10 has a substantially rectangular planar shape in a plan view, and the outlet of the flow path 22 where the suction port of the fan 24 and the ozonolysis filter 26A are disposed is on the diagonal of the substantially rectangular shape. It is located on the opposite side.
Since the suction port of the fan 24 and the outlet side of the flow path 22 are arranged diagonally on the opposite side, the function of the header area 8 is sufficiently exhibited, and the plurality of through holes 12 provided in the partition plate 10 A gas containing an oxide anion can be more uniformly introduced into the second region 6.

  Furthermore, in order to allow the gas containing superoxide anion to more uniformly flow into the entire area of the second area 6, the size of the through hole 12 arranged at a position far from the ozonolysis filter 26A in a plan view is close to the position Making the installation density of the through holes 12 disposed at a position far from the ozonolysis filter 26A higher than the installation density of the through holes 12 disposed at a near position. Is also conceivable.

  In addition, when the storage position of food (for example, vegetables, fruits, etc.) having a high possibility of the presence of many pesticide residues in the second area 6 is determined, the possibility of many pesticide residues being high is high. It is also conceivable to increase the size of the through hole 12 above the storage position of the food or to increase the installation density. In addition, it is also conceivable to dispose the storage position of the food, which is likely to have a large amount of residual pesticides, in the vicinity of the ozonolysis filter 26A in plan view.

  In the above embodiment, the ozonolysis filter 26A is disposed on the outlet side of the flow path 22, but for example, the ozonolysis filter 26A is attached to the upper surface of the partition plate 10 and the superoxide passes through the ozonolysis filter 26A. A gas containing anions can be made to flow immediately through the plurality of through holes 12 into the second area 6 where the food is stored.

In the above embodiment, although the case where the first region 4 is configured by the header region 8 and the flow passage 22 is shown, the present invention is not limited to this, and the flow passage 22 (gas supply unit 20) is not limited to the first. It may be disposed outside the area 4. In this case, the header region 8 (first region 4) and the second region 6 overlap each other in plan view, and the partition plate 10 is disposed therebetween. In this case, a plurality of through holes 12 can be provided above the entire area of the second area 6.
In addition to the case where the first region 4 is above the second region 6 via the partition plate 10, the case where the first region 4 is below the second region 6 or the first In some cases, the area 4 and the second area 6 may be disposed on the left and right.

As shown in FIGS. 1 and 2, in the present embodiment, an additional ozonolysis filter 26B is disposed between the fan 24 and the discharge device 30 in the flow path 22. As the additional ozonolysis filter 26B, the same one as the above ozonolysis filter 26A can be used. The additional ozone decomposition filter 26B can decompose remaining ozone contained in the gas drawn from the second region 6 to suppress an increase in the ozone concentration of the circulating gas.
Since the superoxide anion generated by the additional ozonolysis filter 26B disappears with time, there is no possibility that the superoxide anion concentration of the circulating gas will rise.

<Discharger>
FIG. 3 is a perspective view schematically showing the structure of the discharge portion 32 of the discharge device 30 shown in FIG. The discharge device 30 includes a discharge portion 32 as shown in FIG. 3 inside the casing. In the discharge portion 32 of the discharge device 30, a needle-like electrode 32A extending in a direction perpendicular to the flow of gas in the flow passage 22 is disposed, and extends along the extending direction of the needle-like electrode 32A. A first discharge device flow channel 34 is formed. Furthermore, a second discharge device internal flow passage 36 is also provided along the flow of gas in the flow passage 22 (see the broken arrow in FIG. 3).

In the present embodiment, the high voltage generated by the high voltage generator 38 is applied to the electrode 32A to generate discharge, whereby ions are generated in the vicinity of the needle-like electrode 32A, and the needle-like electrode 32A is extended. Ions fly out along the direction of existence. Here, since the electrode 32A extends in a direction perpendicular to the flow of gas in the flow path 22, ozone and ions can be efficiently generated. Since the ion emission direction is the extension direction of the electrode 32A, ions can be more efficiently generated by forming the first discharge device flow channel 34 along the extension direction of the electrode 32A.
In addition to this, since the second discharge device inner flow passage 36 is also provided along the gas flow of the flow passage 22, pressure loss can be suppressed, and the flow velocity of the gas flowing into the ozonolysis filter 26A is suppressed. Thus, the function of the ozonolysis filter 26A can be enhanced.

In the present embodiment, the first discharge channel in the discharge device 34 is formed to include two electrodes 32A and to extend to both sides of the flow path 22 along the extension direction of the two electrodes 32A. It is possible to form a gas flow in which the spread flow rate is sufficiently suppressed. As a result, sufficient generation of ozone and ions can be realized, and ozone can be efficiently decomposed by the catalyst of the ozonolysis filter 26A disposed on the outlet side of the flow path 22.
However, the present invention is not limited to the case where two electrodes are provided, and the case where one electrode is provided or three or more electrodes may be provided.

<Humidity control filter>
FIG. 4 is an exploded perspective view schematically showing the structure of the humidity control filter 28 shown in FIG. The humidity control filter 28 is disposed in the header area 8 and, as shown in FIG. 2, there is an opening at a position corresponding to the humidity control filter 28 of the ceiling member 16. Thus, the moisture contained in the gas in the header area 8 can be absorbed by the humidity control filter 28 and released to the outside of the header area 8 (decomposition device 2).
As shown in the exploded perspective view showing the humidity control filter 28 in FIG. 4 in an enlarged manner, a plurality of filter bodies 28A are disposed between the upper case 28B1 and the lower case 28B2, so Water can be sufficiently absorbed and released to the outside. As the filter body 28A, for example, a highly absorbent fiber-blended sheet having high moisture absorption and moisture release performance can be used.

  As described above, since the humidity control filter 28 capable of releasing the moisture contained in the gas in the header region 8 to the outside is provided, even if a large amount of food is stored in the second region 6, it is decomposed. Water droplets can be prevented from adhering to the inner wall of the device 2. By setting the filter main body 28A of the humidity control filter 28 to have a predetermined density, it is possible to perform internal dehumidification without substantially leaking ozone to the outside.

(Automatic valve)
FIG. 5 is a side view and a side cross sectional view showing the side and the cross section along A-A in FIG. 6 is a side sectional view showing the automatic valve 60 of FIG. 5 in an enlarged manner. In FIGS. 5 and 6, (a) shows the automatic valve 60 in the closed state, and (b) shows the automatic valve 60 in the open state.
As described above, since the disassembling apparatus 2 according to this embodiment includes the draw-type container 40, it can be said that the disassembling apparatus 2 has an opening that can open and close the second region 6 to the outside. As shown in FIG. 5, in the decomposition apparatus 2 according to this embodiment, an automatic valve 60 capable of opening and closing the flow path 22 to the outside is provided at a position on the rear side opposite to the opening of the flow path 22. .

  When the container 40 is pulled out to the front and the second region 6 is open to the outside, control is performed to operate the fan 24 and open the automatic valve 60. By this control, even when the second region 6 is released to the outside, the gas containing ozone is made to flow out to the opposite side of the opening (see the dotted arrow in FIG. 6B), Negative pressure in the second region 6 can prevent the leakage of ozone from the opening side.

The automatic valve 60 may be opened and closed using an actuator such as a solenoid, or may be mechanically operated as an automatic valve as shown in FIGS. 5 and 6.
The automatic valve 60 shown in FIGS. 5 and 6 includes a valve main body 62 that rotates about a rotation shaft 62A to open and close, and a hold arm 64 that presses the valve main body 62 from the outside. The hold arm 64 rotates about the rotation axis 64A. A pressing member 66 biased by a compression spring 68 is attached to one end 64B. The other end 64C is adapted to abut the rear side of the container 40 when the drawer type container 40 is in a closed and closed state.

  With such a structure, when the container 40 as shown in FIG. 6A is in the closed state, the hold arm 64 in contact with the container 40 at the other end 64C (specifically, one end The valve body 62 is pushed and maintained in the closed state by the pushing member 66) biased by the compression spring 68 attached to 64B. On the other hand, when the container 40 is pulled toward the front to be in the released state, the contact between the container 40 and the hold arm 64 is released, and the hold arm 64 rotates clockwise about the rotation shaft 64A. . As a result, the pressing of the valve main body 62 by the hold arm 64 is released, and the valve main body 62 rotates clockwise about the rotation shaft 62A. As a result, the automatic valve 60 is in the open state, and the flow path 22 is in communication with the outside.

  As described above, in the automatic valve 60 shown in FIGS. 5 and 6, the valve can be mechanically opened and closed according to the opening and closing of the drawer type container 40 without the need for electrical control.

(Control processing for ozone leak prevention)
FIG. 7 is a flowchart showing an example of control processing of the decomposition device 2 according to one embodiment of the present invention. A control process for preventing ozone leakage using the automatic valve 60 will be described with reference to FIG. This flowchart shows control processing in the case of using an automatic valve which is opened and closed using an actuator.
First, it is determined whether a switch for driving the disassembling device 2 is turned on (step S2). If it is determined that the switch is not turned on (NO) in this determination, this determination processing is repeated as it is. That is, it is in a standby state.

  If it is determined at step S2 that the switch is turned on (YES), then discharge by the discharge device 30 is started (step S4), and driving of the fan 24 is started (step S6), The LED provided on the outer front of the disassembling device 2 is blinked (step S8). Then, it is determined whether or not the measurement time of the timer which has started the measurement when the switch is turned on has passed 2 hours (step S12). In the meantime, it is determined whether or not the pullout type container 40 is pulled out to be in an open state (a state in which the second region 6 is released to the outside) (S10).

  If it is determined that 2 hours have elapsed (YES) in step S12 without the pullout container 40 being in the open state, the residual pesticide attached to the surface of the food stored in the second region 6 is Since it can be determined that the battery has been sufficiently disassembled, the discharge by the discharge device 30 is stopped (step S14). Then, it is determined whether or not the measurement time of the timer which has started the measurement at the discharge stop has elapsed for 3 minutes (step S16). In this determination, if it is determined that 3 minutes have not elapsed (NO), the standby state is established, and the fan 24 continues operating. If it is determined in step S16 that 3 minutes have elapsed (YES), the fan 24 is stopped (step S18), and the LED is changed from blinking to lighting (step S20).

  Then, it is determined whether or not the drawer type container 40 is in the open state (step S22). If it is determined that the drawer-type container 40 is not in the open state (NO) in this judgment, the standby state is established, and if it is determined that the drawer-type container 40 is in the open state (YES), The LED is turned off (step S24), and the series of control processing ends.

If it is determined in step S10 that two hours have passed since the switch was turned on (YES in step S12), the discharge device 30 is determined to be in the open state (YES). The discharge due to is stopped (step S26), the automatic valve 60 in the closed state is opened (step S28), and the LED is turned off (step S30).
By this control, even when the container 40 is opened and the second region 6 is released to the outside, the gas containing ozone is allowed to flow out to the opposite side (rear side) of the opening. The negative pressure in the second region 6 can prevent the leakage of ozone from the opening side.

  Then, when it is detected that the container 40 is in the open state, it is determined whether or not the measurement time of the timer which has started the measurement has exceeded 3 minutes (step S32). In this determination, if it is determined that 3 minutes have not elapsed (NO), the standby state is established, and the fan 24 continues to operate during that time. If it is determined in step S32 that 3 minutes have elapsed (YES), the fan 24 is stopped (step S34), and the automatic valve 60 is closed (step S36).

Next, it is determined whether or not the withdrawal type container 40 has been closed (step S38). In this judgment, if it is determined that the withdrawal type container 40 is not in the closed state (NO), that is, the container 40 is still in the open state, a series of control processing is ended.
If it is determined at step S38 that the drawer type container 40 is in the closed state (YES), there is no possibility that ozone leaks, so the process returns to step S4, and discharge by the discharge device 30 is performed again. It starts and starts driving the fan 24 to resume a series of control processes for decomposing the residual pesticide.

That is, in the control process shown in FIG. 7, when the container 40 is closed within 3 minutes when the withdrawal type container 40 is in the open state during the process of decomposing the residual pesticide, it is automatically performed. Then, the control processing is repeated from the beginning to the processing for decomposing the residual pesticide, and if the container 40 is still in the open state after 3 minutes, the series of control processing is ended. Therefore, in the latter case, in order to restart the process of decomposing the residual pesticide, the user needs to turn on the switch for driving the decomposition device 2 again.
In the above flow chart, the automatic valve opening and closing is performed by control processing (a signal is sent to open and close the valve), but when using the mechanical automatic valve 60 as shown in FIG. 5 and FIG. The automatic valve 60 can be mechanically opened and closed according to the opening and closing of the container 40 without the need for processing.
