Fig. 8 represents each parts constituting locked hand 106, and Fig. 8 (a) is from standing that its rear side is observed Body figure, Fig. 8 (b) is its exploded perspective view, and Fig. 8 (c) is the line B-B sectional view in Fig. 8 (a). Additionally, in Fig. 8 (c), for simplifying diagram, eliminate for (the propping up of upper strata container 102 that unlock Hold fixing) the diagram of a part of mechanism.

As shown in Fig. 8 (a), locked hand 106 is configured to possess: have the catalyst of intercommunicating pore 106d Cover 106f；The handle shell rear portion 106g installed for catalyst cover 106f；It is installed on handle shell rear portion 106g The handle shell front portion 106h of face side；And be integrally formed with by bottom 106a (with reference to Fig. 5) Handle pulling rod 106j.And, as shown in Fig. 8 (b), if pulling down catalyst cover from locked hand 106 106f, then configure platinum catalyst 118 in the inside of locked hand 106 in the way of extending in left-right direction. This platinum catalyst 118 is configured at the inside of locked hand 106, in order to avoid for the handle 106 that unlocks The mechanism (not shown) of locking.

In Fig. 8 (c), the arrow of thick line represents the direction of the flowing of air.As shown in Fig. 8 (c), platinum Catalyst 118 can by intercommunicating pore 106c, 106d, 106e with the air contact in each space.And And, though not illustrated by arrow, but the air in each space also can not contact with platinum catalyst 118 and to Other space supply.

Herein, platinum catalyst 118 is illustrated.Platinum catalyst 118 is different from photocatalyst, even if being There is no the light of LED etc., the ethylene contained by the air in each space and trimethylamine are decomposed yet Catalyst.By utilizing platinum catalyst 118 decomposing ethylene, thus produce carbon dioxide and steam.And And, owing to the carbon dioxide produced supplies in each space via intercommunicating pore, it is stored in each space so closing The pore of vegetable and suppress the breathing of vegetable, thus the minimizing of the nutritional labeling that caused by breathing of suppression, dry Dry, thus maintain the freshness of vegetable for a long time.Additionally, as the setting place of platinum catalyst 118, not It is defined in locked hand 106 internal, catalyst incorporating section is set at least one wall separating each space, And platinum catalyst 118 is received in this catalyst incorporating section.In the case of Gai, in catalyst incorporating section also shape The intercommunicating pore of Cheng Youyu each space connection.And, it is also possible to it is constructed as below: at any one wall in each space Face arranges catalyst incorporating section, and forms intercommunicating pore at the wall separating each space.

Further, if the water dissolution existing for surface of the carbon dioxide vegetable etc. that is stored in vegetable compartment 100, Then the surface of vegetable etc. is acid.But, if produce the trimethylamine of aobvious alkalescence, then front three when being dissolved in water Amine is also dissolved in the water existing for vegetable surface, thus has neutralized the acidated vegetables because of the dissolving of carbon dioxide Dish surface.But, in refrigerator 10, by utilizing platinum catalyst 118 to decompose trimethylamine, thus it is stored in The surface of the vegetable etc. of vegetable compartment 100 is acidity, and then the propagation of the microorganism of suppression vegetable surface.

Platinum catalyst 118 in refrigerator 10 is in granular form, and is contained in locked hand with the state being contained in bag 106.Thus, granular platinum catalyst 118 is suitable in bag when pull-out and receiving upper strata container 102 Local mixing.It is therefore prevented that relative to granule only from a direction ingress of air, thus maintain catalyst merit Energy.Additionally, be not limited to platinum catalyst 118, it is possible to use other transition-metal catalyst.Make For transition-metal catalyst, in refrigerator 10, use and have punctulate silicon dioxide (mesoporous silicon oxide), And the micropartical of the transition metal such as platinum, ruthenium is supported in the inside of this pore.

Fig. 9 is the axonometric chart viewed from above of vegetable container cover 105.As described above, at vegetable container The upper surface of the face side of cover 105 is formed with embossed portion 105a.From the lateral vegetable of this embossed portion 105a The internal irradiation of room 100 is from the light of not shown LED illumination.Further, formed at vegetable container cover 105 The lower section having multiple intercommunicating pore 105c, this intercommunicating pore 105c to will be formed in vegetable container cover 105 is configured Sheaf space 101C on rear side between upper strata container 102 (not shown in Fig. 9) and vegetable container cover 105 Inside and outside connection.This intercommunicating pore 105c is 24 in refrigerator 10, and includes being formed at vegetable compartment 100 The back side on the right side of the vicinity of cold air return port (not shown) and formed.

Figure 10 is the axonometric chart observed from below of vegetable container cover 105, and Figure 10 (a) is its overall diagram, Figure 10 (b) is the figure in the C portion of enlarged representation Figure 10 (a).Figure 10 (a) represents from vegetable container The situation of vegetable container cover 105 is observed in the lower section of the face side of cover 105.As shown in Figure 10 (a), vegetables The lower surface of dish jar 105 (towards the face of inside of upper strata container 102), is configured with rising plate 105b (moisture occlusion releasing parts).Rising plate 105b is to be formed by resin fibres such as braiding PET Flat parts, bypass air through and absorb the moisture of liquid.And, the moisture of moisture absorption can phase Rising (release) for air.

As shown in Figure 10 (b), at the lower surface of vegetable container cover 105, with by vegetable compartment 100 The mode opposed for intercommunicating pore 105c of outer connection is formed with flank 105d.And, by being formed at connection Space 105e between hole 105c and flank 105d inserts rising plate 105b, comes at vegetable container cover 105 Lower surface keep rising plate 105b.Further, by keeping rising plate 105b at space 105e, thus connect Through hole 105c is positioned under the vertical projection of rising plate 105b, and intercommunicating pore 105c is inaccessible by rising plate 105b. Thus, although the air containing moisture of the inside of lower layers of containers 101 and upper strata container 102 is by connection Hole 105c is to the outside discharge of vegetable compartment 100, but suppression cold air directly passes through from the outside of vegetable compartment 100 Intercommunicating pore 105c enters the inside of vegetable compartment 100.

Further, if the air of the inside of sheaf space 105C contacts with vegetable container cover 105 on rear side, then have Moisture contained by this air condenses and produces the probability of dew in vegetable container cover 105.But, produce The rising plate 105b moisture absorption that raw dew is configured by the whole region of the top throughout upper strata container 102. Therefore, suppression dew falling to rear side upper strata space 10C.

Figure 11 is the side view of vegetable container cover 105.In Figure 11, it is configured at vegetable container cover 105 times Lower layers of containers 101 and the upper strata container 102 of side are represented by imaginary line.Rising plate 105b is with towards upper strata The mode of the inside of container 102 is installed on the lower surface of vegetable container cover 105.Further, though in fig. 11 Not shown, but above vegetable container cover 105, circulation has the cold wind for cooling down vegetable compartment 100.Therefore, The cold wind of circulation circulates in the way of the rising plate 105b that intercommunicating pore 105c exposes by contact.Thus, by The water of the liquid that rising plate 105b absorbs becomes steam and discharges to the cold wind of circulation.It is to say, Moisture in vegetable compartment 100 by rising plate 105b moisture absorption, and the moisture of moisture absorption via intercommunicating pore 105c to Discharge outside vegetable compartment.It is therefore prevented that rising plate 105b taken in excess water and water droplet are to upper strata container 102 Drip in inside.

Figure 12 is the axonometric chart observed from face side of lower layers of containers 101.The inside of lower layers of containers 101 by Separator 103 is divided into face side and rear side.And, in the inside shape of the rear side of lower layers of containers 101 Become to have rear side lower layer space 101A, and lower layers of containers 101 face side to be internally formed front side empty Between 101B (not shown in Figure 12).In the rear side of lower layers of containers 101, with to accompanying by dew The mode that face (condensation face 101a, not shown in Figure 12) carries out covering is provided with lower layers of containers cover 110. Hereinafter with reference to Figure 16, the situation of the generation of dew can be illustrated.

Figure 13 is the axonometric chart observed from rear side of lower layers of containers 101.As described above, lower floor is held The inwall of the left and right of lower layers of containers 101 is located at by the separator 103 that the inside of device 101 carries out dividing by a pair Guide part 104 supports.Further, at the lower layers of containers being provided with lower layers of containers cover 110 (with reference to Figure 12) The face (that is, lateral surface) of the opposition side of 101, is provided with from cool-air feed guiding mechanism 141 (with reference to figure 3) face of brushing 113 of cold air and make the water of condensation in the face accompanying by above-mentioned dew cold to this The rising box 112 that gas is rising.

Figure 14 is mounted to the axonometric chart of the parts of the sidewall of the rear side of lower layers of containers 101, Figure 14 (a) Being mounted to the lower layers of containers cover 110 of medial surface, Figure 14 (b) is mounted to the shell 112 of lateral surface. As shown in Figure 14 (a), it is formed with multiple slit 110a at lower layers of containers cover 110.The slit 110a formed Towards be formed as from face side rearwardly effluent moves time downward.Even if because of along such direction shape Become slit 110a and in the case of the surface of lower layers of containers cover 110 creates dew, it is also possible to make this Dew arrives the rising plate 112e (aftermentioned) being configured at its rear side by slit 110a, thus prevents Dew falls to rear side lower layer space 101A.

It addition, the surface of this lower layers of containers cover 110 is implemented processing patterns.That is, lower layers of containers cover 110 Surface roughened.Thus, it is difficult to by improving the hydrophilic of lower layers of containers cover 110 form water droplet, from And user can be difficult to notice the existence of water droplet.It is therefore prevented that user feels that water droplet may fall this One uneasy sense.

Further, as shown in Figure 14 (b), rising box 112 is configured to possess: accommodate with in Figure 14 not The shell 112a of the cover 112c that the mode that the rising plate 112d (with reference to Figure 15) of diagram carries out covering embeds；With And the outer casing underpart 112b of fixedly embedded cover 112c.

Figure 15 is mounted to the exploded perspective view of the rising box 112 of the external back surface of lower layers of containers 101, figure 15 (a) is the state being provided with rising plate 112d, and Figure 15 (b) is the shape having pulled down rising plate 112d State.State representation shown in this Figure 15 (a) starts to make cover 112c to face side from the state shown in Figure 14 Rotate and taken off so that the state exposed of rising plate 112d.This point is illustrated, shell 112a Downside end and cover 112c downside end the most locking.Therefore, if such as Figure 15 (a) Shown in, pulling down cover 112c from shell 112a, then cover 112c is with this locking part for axle center rotating, and Side shifting downwards.Thus, the rising plate 112d of tabular exposes in face side.

Further, in the lower end of the rising plate 112d of this tabular, it has been integrally connected from just with rising plate 112d The rising plate 112e that the lateral rear side in face extends.Therefore, by the transpiration of the inside being configured at rising box 112 The one thing that plate 112d and rising plate 112e is constituted utilizes resin fibre to constitute and in L-shaped shape.

The material of these rising plate 112d, 112e is identical with the rising plate 105b with reference to Figure 10 explanation Material, thus omit detail explanation.And, condense in medial surface (Figure 16 of lower layers of containers 101 Shown condensation face 101a) water along this medial surface drippage by rising plate 112e moisture absorption, but this can be existed Below it is described in detail.And, the water of absorption spreads at rising plate 112e and rising plate 112d successively, Thus arrive rising plate 112d.

As shown in Figure 15 (b), the rear side at rising plate 112d is configured with guard member 112f, this protection Part 112f is formed with the air vent 112g that can make air break-through.Rear side at this transpiration box 112 circulates Cold air contacted with the rear side of rising plate 112d by this air vent 112g.Thus, rising plate is arrived The moisture of 112d is rising to the cold air of contact.

Figure 16 be represent make the moisture of inside of rear side lower layer space 101A condense and make the water of this condensation to The figure of the situation when outside of vegetable compartment 100 is rising.To the rear wall being integrally formed in lower layers of containers 101 The face of brushing 113 of cold air brush the cold air from cool-air feed guiding mechanism 141.Thus, face is brushed The wall temperature of the vicinity of 113 is lower than the wall temperature of other parts.Therefore, with its part constituting lower layers of containers 101 The air that contacts of internal face (condensation face 101a) in moisture condensation, and produce dew 117.Produce Dew 117 because of the deadweight clearance portion 114 from the bottom of the rear wall being formed at lower layers of containers 101 downward Flow down outside layer container 101, flow to rising plate 112e additionally by the slit 112c1 being formed at cover 112c Under.Additionally, clearance portion 114 can also be formed at other position of the bottom of lower layers of containers 101, the most also The bottom surface of lower layers of containers 101 can be formed at and be formed at rear side.

Moisture by rising plate 112e moisture absorption is in the diffusion inside of rising plate 112e, 112d.Now, inhale Wet moisture spreads upward in the inside of the rising plate 112d configured along the vertical direction.And, in transpiration The moisture of plate 112d internal diffusion is as described above to the cold air transpiration contacted with rising plate 112d, thus vegetables The moisture of the air of the inside of dish room 100 is to the outside discharge of vegetable compartment 100.So, rising plate 112e, 112d makes the dew flowed down at the inner surface of rear wall from being formed at the clearance portion 114 of rear wall to lower floor It is sucked out outside container 101 and discharges to cold air.Now, by making the rear wall of cold air and lower layers of containers 101 Directly contact, and make rear wall itself become condensation face, thus metal height is set unlike the past and leads Thermal part, it is possible to control the humidity of compartment interior with simple structure.

In the refrigerator 10 of present embodiment, as shown in figure 16, the length of the above-below direction of rising plate 112d (highly) roughly the same with the length of the above-below direction in the face of brushing 113 (highly).Herein, rising plate The length the most substantially phase of the length of the left and right directions of 112d and the left and right directions in the face of brushing 113 With.Thus, the area of rising plate 112d is roughly the same with the area in the face of brushing 113.And, by Cold air is brushed in face of brushing 113 as the lateral surface of lower layers of containers 101, and makes the moisture in refrigerator from configuration Rising box 112 in its underpart is rising such that it is able to effectively utilize the outside of less lower layers of containers 101 Face, controls its internal humidity.

Herein, the variation of the lower layers of containers cover 110 of the rear side being installed on lower layers of containers 101 is said Bright.

Figure 17 is the figure of the variation of the lower layers of containers cover 110 representing the inside being installed on lower layers of containers 101, The axonometric chart of the rising unit enclosure 116 being that instead of lower layers of containers cover 110 and install.Shown in Figure 14 (a) Lower layers of containers cover 110 is plate-shaped, but can replace this lower layers of containers cover 110 and use the transpiration of L-shaped shape Unit enclosure 116.

In rising unit enclosure 116, it is identically formed with product with the slit 110a of above-mentioned lower layers of containers cover 110 Multiple slit 116a as the flowing of raw air downward.Wherein, on the right side of rising unit enclosure 116 Side, is formed with the opposed parts 116b opposed with the side, right side of lower layers of containers 101.With above-mentioned lower floor Jar 110 is identical, and the surface of this transpiration unit enclosure 116 is implemented processing patterns.

Figure 18 be when the rising unit enclosure 116 shown in Figure 17 is installed on the inside of lower layers of containers 101, The axonometric chart of the inside of lower layers of containers 101 is represented from face side.Rising unit enclosure 116 is by not shown spiral shell Stricture of vagina part etc. is fixed on the inwall of lower layers of containers 101.As illustrated with reference to above-mentioned Figure 16, refrigerator 10 In, by brushing cold air to the face of brushing 113 (with reference to Figure 16) of the lateral surface being formed at lower layers of containers 101, Can on purpose produce dew.

But, brush face 113 close with the lateral surface on the right side of lower layers of containers 101.Therefore, if by Brush face 113 and brush cold air to cool down lower layers of containers 101, then its cold and hot medial surface transmission the most to the right, Thus medial surface on the right side of this also produces dew sometimes.Therefore, as shown in figure 18, in order to the most right The dew that medial surface on right side produces reclaims, and the right side of side is configured with and possesses opposed parts overleaf The rising unit enclosure 11 of 116b.Further, the rising unit enclosure 116 of this L-shaped shape is also formed with in bottom surface Dew receiving portion, and this bottom surface have rearwardly side decline such tilt.Therefore, even if on right side The dew that side produces arrives bottom surface, it is also possible to rearwardly side guides, the rising plate 112e of final utilization, 112d absorbs moisture it is thus possible to discharge relative to cold air.

In the rising side, right side of unit enclosure 116, the lower section of the most opposed parts 116b, be formed have from Face side declines the groove portion 116c of such inclination towards rear side.And, cooling lower layers of containers 101 Side, right side result and in the case of the surface of opposed parts 116b creates dew, utilize from The groove portion 116c of right side wall sidewall slope backward, accepts the dew fallen because of deadweight, thus anti- Only fall to the inside of lower layers of containers 101.And, the dew of undertaking arrives in groove portion 116c circulation Rear side, and pass through at the dew discharge portion 116d to arrange in the way of slit 116a, and to joining It is placed in the rising plate 112e supply of the rear side of rising unit enclosure 116.And, so, at opposed parts The dew that the surface of 116b produces is also to the outside discharge of vegetable compartment 100.That is, due to from rear wall Adjacent right side wall is installed on the inner surface of container to the dew guide member that rear wall extends, so not only At the dew of the inner side of rear wall condensation, the dew condensed in the inner side of right side wall is also in rear wall Side supplies, and finally can be discharged to the outside of rear wall by rising plate 112e.

Additionally, by not shown between the inwall of lower layers of containers 101 with the opposed faces of opposed parts 116b Screw elements etc. are fixed, and produce some gaps.But, owing to air layer, institute can be produced between which Poor with heat conductivility, therefore, it is difficult to produce dew.Therefore, fully inhibit and produce between these gaps Raw dew.

It follows that with reference to Figure 19～Figure 22, to during the vegetable compartment door 6 of pull-out refrigerator 10, lower layers of containers The action of 101 grades illustrates.Additionally, in Figure 19～Figure 22, for simplifying diagram, eliminate above-mentioned in The diagram of a part for the parts illustrated.

Lower floor when Figure 19 is to accommodate lower layers of containers 101 in the vegetable compartment 100 of refrigerator 10 main body completely The sectional view of container 101.Figure 19 represents locked hand 106 on the direction from face side rearwardly side Vicinity when having cut off, section in the case of left and right directions is observed.As shown in figure 19, when at ice When accommodating lower layers of containers 101 in case 10, vegetable container cover 105 is to the opening as lower layers of containers 101 Lower layers of containers 101 and entirety (that is, front space 101B and the rear side upper strata of upper strata container 102 Space 101C) cover.Thus, the air-tightness of the inside in these spaces uprises.Therefore, for receiving Receive the whole space in container 101, the most not only rear side lower layer space 101A also for front space 101B And sheaf space 101C on rear side, it is possible to internal gas concentration lwevel is remained more than 1000ppm. Further, owing to rising plate 105b is constituted in the way of being positioned at the vertical projection of the upper sheaf space 101C of rear side, It is possible to more efficiently the humidity in sheaf space 101C on rear side is controlled.

Further, now, the rising plate 105b (reference of the lower surface being configured at vegetable container cover 105 is utilized In Figure 10, Figure 19 not shown) and rising box 112 (with reference to Fig. 6, not shown in Figure 19) control The humidity of the inside of vegetable compartment 100.And, each space constituting vegetable compartment 100 holds by being formed at upper strata The intercommunicating pore 102 (with reference to Fig. 4, not shown in Figure 19) of the bottom surface of device 102, it is formed at locked hand 106 Intercommunicating pore 106c, 106d, 106e (with reference to Fig. 8, not shown in Figure 19) and connect, thus control The overall humidity of vegetable compartment 100.

Figure 20 be represent when slightly drawing out lower layers of containers 101 in refrigerator 10, specifically to connect front side empty Between the sectional view of 101B lower layers of containers 101 when also being pulled out outside vegetable compartment 100.If to front layback Go out lower layers of containers 101, the most also to face side pull-out upper strata container 102.Wherein, upper strata container 102 At the relative invariant position of the inside of lower layers of containers 101, even if pulling out lower layers of containers 101 to face side, Upper strata container 102 also keeps supporting and fixing constant in the top of rear side lower layer space 101A.

Further, if pulling out lower layers of containers 101 to face side, then with this pull-out action, vegetable container cover 105 Slide in the upper end of upper strata container 102, and the upper end 105d of vegetable container cover 105 and locked hand 106 Face side contacts side surfaces.Thus, even if pulling out lower layers of containers 101, the most only front space 101B to face side To external open (exposing from vegetable container cover 105), on rear side, the opening of sheaf space 101C is held by vegetable Device cover 105 covers, thus becomes the bubble-tight state maintaining the upper sheaf space 101C of rear side.Therefore, Compare in front space 101B, rear side is better able in sheaf space 101C maintain from vegetable etc. higher The concentration of the carbon dioxide produced.Further, when to face side pull-out lower layers of containers 101, vegetable container cover The amount of movement of 105 is fewer than the amount of movement of upper strata container 102.Therefore, think only to use front space at user In the case of 101B, it is not necessary to carry out vegetable container cover 105, the operation of locked hand 106.

If starting to pull out lower layers of containers 101 to face side further from the state shown in Figure 20, then vegetable is held Device cover 105 keeps the inside staying refrigerator 10 main body constant, and becomes and pull out lower layers of containers in this condition 101.It is to say, when also having pulled out the upper sheaf space 101C of rear side outside vegetable compartment 100, not only before The opening of space, side 101B, on rear side, a part of opening of sheaf space 101C is also from vegetable container cover 105 Expose.

Figure 21 is to represent after being completely pulled out lower layers of containers 101 in refrigerator 10, by the handle that unlocks The sectional view of 106 situations when opening wide the upper sheaf space 101C of rear side.By operation locked hand 106, And vegetable container cover 105 is with the upper end 105d of the face side of vegetable container cover 105 (in Figure 21 not shown) The mode being positioned at side more top than the upper end of locked hand 106 moves.Thus, on rear side sheaf space 101C to External open, and can be to face side pull-out upper strata container 102.

Refrigerator when Figure 22 is to be completely pulled out lower layers of containers 101 and upper strata container 102 in refrigerator 10 The sectional view of 10.If being completely pulled out upper strata container 102, then the lower end mounting of the face side of upper strata container 102 In the upper end of separator 103, it is possible to stably take out vegetable etc..Further, when being completely pulled out upper strata During container 102, vegetable container cover 105 somewhat has towards face side from rear side and configures obliquely.That is, Vegetable container cover 105 is with the aspect ratio of the above-below direction of the end (above-mentioned upper end 105d) of face side The mode slightly higher for end 105e of rear side is configured at the inside of refrigerator 10.Thereby, it is possible to guarantee significantly To the space (conveying end) of the external open of upper strata container 102, and become easily to take out vegetable etc..

In the present embodiment, owing to the trimethylamine of the gas as alkalescence is at short notice by platinum catalyst 118 decompose, so suppressing the neutralization on the surface of the vegetable being acidified because of the dissolving of carbon dioxide such that it is able to Improve the acid degree on surface.That is, in the case of vegetable is accommodated in accommodating container, relative to its table in the past The pH in face rises, and the pH on its surface reduces in the present embodiment.Its result, suppresses the table vegetable The ferment of face generation, microorganism, thus the carrying out that suppression is addled.Further, if owing to trimethylamine is decomposed also Produce carbon dioxide, so compared with the situation employing photocatalyst, making the effect that carbon dioxide increases also Higher.Actual carried out experiment after, it is known that in the case of employing platinum catalyst 118, have with use The situation of photocatalyst compares the carbon dioxide generative capacity of about 2 times.Therefore, even big region, also The carbon dioxide that can make inside increases.

Figure 23 be represent use photocatalyst and only plan improve on rear side of lower layer space vegetable freshness with Toward structure and present embodiment structure in, the vitamin of vegetable that determines in each space of accommodating container The figure of the result of the experiment of the reserved of C.Figure 23 (a) is that sheaf space 101C storage is cut away on rear side The Fructus Citri tangerinae of 1/2 also compares the figure of the vitamin C reserved after 7 days, it is known that compared with the past the highest 21%.Figure 23 (b) is to cut away the Herba Alii fistulosi of 1/2 in front space 101B storage and compare after 6 days The figure of vitamin C reserved, it is known that compared with the past the highest by 22%.Figure 23 (c) is in rear side lower floor Space 101A receives Brassica campestris L and compares the figure of the vitamin C reserved after 7 days, it is known that with in the past On an equal basis.That is, according to present embodiment, not only rear side lower layer space 101A, and sheaf space 101C on rear side And the nutritional labeling in vegetable is also difficult to be consumed because of aging action in front space 101B, it is thus possible to Enough with state that nutritive value is higher longer keep vegetable.

Above, referring to the drawings present embodiment is illustrated, but the present invention is not limited to above-mentioned reality Execute mode.
