Then, the effect to above-mentioned composition illustrates.

First, refrigeration is illustrated with the detailed configuration of cooler 24.As shown in Figure 2, possess as refrigerant Entrance head 24a, as refrigerant outlet head 24b, by the flat tube 24c connected between these 24a and head 24b, It is arranged between each flat tube 24c and the fin 24d of wavy heat absorption is formed as by metal material, is arranged at the head of entrance side 24a and the entrance side connecting portion 24e that is connected with refrigerant piping (omit illustrate) and be arranged at outlet side head 24b and with The outlet side connecting portion 24f of outside pipe arrangement (omitting diagram) connection.Now, it is provided with flat tube 24c position i.e. main part 24g Outer be formed as relatively thin substantially rectangular-shape.

Head 24a and head 24b is formed as hollow cylindrical, and as mutual hollow bulb (omitting diagram) by each flat The state that pipe 24c is respectively communicated with.More specifically, as shown in Figure 3, flat tube 24c profile is formed as flat, and Multiple stream 24h for refrigerant flowing are internally formed at it.Then, by each stream 24h by head 24a's and head 24b Mutual hollow bulb connection.

By being arranged such multiple stream 24h, thus with being provided with the type of a stream being relatively large in diameter in the past Stream compare, refrigerant and flat tube 24c contact area increase.Thus, efficiently passed from refrigerant to flat tube 24c Heat.Further, since flat tube 24c contacts with fin 24d, therefore also efficiently conducted heat from flat tube 24c to fin 24d.Then, Because fin 24d is formed as wavy, therefore the contact area i.e. heat exchange area of itself and air can be made further to increase.

In this way, the refrigeration of multi-streaming type can carry out efficient heat exchange with cooler 24 between air.For example, refrigeration It is that if same volume, then compared with the cooler of conventional fin-and-tube type, 2~3 times of heat absorption can be expected with cooler 24 Effect, as long as and if the cooler of endothermic effect same can be obtained, then can turn into it is slim wait energy Volume is enough dramatically reduced.Thus, the situation of refrigeration cooler 24 is configured in the rear side in refrigerator 1 as the manner Under, the wasted space for being capable of less rear side i.e. can not be as the space that storeroom utilizes.

In addition, in the case of the manner, as shown in Figure 4, refrigeration cooler 24 is configured as, the head of entrance side 24a turns into lower section, the head 24b of outlet side turns into top.In other words, refrigeration cooler 24 is configured as, and is configured with flat tube 24c position is main part 24g vertical relative to the setting face of refrigerator 1, and is configured as flat tube 24c also relative to setting Face is vertical.In addition, it is described herein vertical, it is not limited to relative to the state that setting face is 90 degree, it is also vertical comprising being substantially considered as State, for example some inclined states.

The refrigerant flowed into refrigeration with cooler 24, used like that from entrance side connecting portion 24e to refrigeration as shown by arrow F Cooler 24 is flowed into liquid condition, after refrigeration turns into gaseous state with evaporation in cooler 24, from the outlet of top Side connecting portion 24f mainly turns into gaseous state and flowed out.Now, the refrigerant of liquid condition is flowed down downwards by gravity, Therefore as schematically shown in Fig. 4 (B), the entrance of refrigerant is arranged below, outlet is disposed over, by This can make the movement of refrigerant smooth, can carry out efficient heat exchange.In addition, Fig. 4 (B) is showed schematically from diagram left Observe the state of the refrigeration cooler 24 shown in Fig. 4 (A) in side.

In addition, refrigeration cooler 24 is, when freeze cycle operates, temperature reduces and produces frost.The frost makes heat exchange Performance reduces, therefore for example enters to be about to the defrosting processing of frost removing according to certain period.In defrosting processing, make accompanying Frost, which melts, to be turned into defrosting water and discharges downwards.Therefore, by as the manner by the main part 24g of refrigeration cooler 24 Vertically configure, thus, it is possible to promote flowing down for defrosting water.Also, by the way that flat tube 24c is also configured as vertically, thus defrosting The water capacity is easily in flat tube 24c by can further deposit into and flow down.

Refrigerator 1 from the description above, can obtain effect as following.

Refrigerator 1 carries out the heat exchange of freeze cycle using the refrigeration of multi-streaming type with cooler 24 (evaporator), refrigerates with cold But device 24 has the flat tube 24c internally formed with multiple stream 24h for refrigerant flowing.

The refrigeration cooler 24 of multi-streaming type is that heat exchange performance is higher as described above, if same performance, then with The cooler of conventional fin-and-tube type, which is compared, can significantly reduce its volume.Further, since slimming can be formed, therefore match somebody with somebody The free degree for putting place also improves.Thereby, it is possible to improve the configuration free degree of refrigeration cooler 24, effective case can be obtained Inner volume can be used in space in the case of storeroom.

In addition, by the way that refrigeration is vertically configured with the main part 24g of cooler 24, the stream thus, it is possible to promote defrosting water Under.In this case, by the way that flat tube 24c is also configured as vertically, the water capacity that thus defrosts is easily in flat tube 24c by energy It is enough further to promote flowing down for defrosting water.

In addition, in the feelings as the manner with refrigeration this 2 evaporators of cooler 24 and freezing cooler 25 Under condition, refrigeration can be carried out per circulating defrosting with cooler 24 according to its actuation cycle.Refrigeration cooler 24 is, if stream Dynamic refrigerant is then cooled, on the other hand, because the temperature inside the box of refrigerating chamber 3 is more than 0 DEG C, so if not flowing refrigeration Agent, then evaporator heating can be defrosted by making refrigeration persistently be rotated with blower fan 35.

Now, the thermal capacity of the refrigeration cooler 24 of multi-streaming type diminishes, thus with the cooler of conventional fin-and-tube type Shortened compared to defrosting time, the good operating of line efficiency can be entered, power saving can be realized.

In addition, entrance side connecting portion 24e and outlet side connecting portion 24f and main part 24g is generally horizontally set, because This can make the length (thickness) of the fore-and-aft direction of refrigeration cooler 24 thinning, can increase storeroom.

In addition, for freezing cooler 25, the effect same with refrigeration cooler 24 can be also obtained.

＜ second methods ＞

Hereinafter, reference picture 5 illustrates to Figure 10 to second method.In second method, to refrigeration cooler 24 The other examples of configuration mode and construction illustrate.

As described above, the lower side in refrigeration with cooler 24, due to defrosting under current, therefore when in its scope (stream Lower region (Rx.Reference picture 7) in configuration refrigeration with blower fan 35 when, carry out defrosting processing when defrosting water possibly flow onto it is cold Hide with blower fan 35.

Thus, for example in the case where configuring as shown in Figure 5 in refrigeration cooler room 36, it may be considered that will use Configured in the fan 60 to the air blast of refrigeration cooler 24 in the position with the general parallel orientation of refrigeration cooler 24.In addition, fan 60 can also be refrigeration blower fan 35.

Thereby, it is possible to prevent from flowing on fan 60 by the defrosting water under gravity stream.In addition, the if refrigeration of multi-streaming type With cooler 24, then it can turn into slim as described above, therefore refrigeration cooler can be arranged on side by side with fan 60 In room 36.

In this case, the lower side of cooler 24 is provided with tank 56 (reference picture 1) in refrigeration, therefore passed through The tank 56 and refrigerating turns into the blocked state of a part on the inside of case with the space of the lower side of cooler 24.When Make under the state in the case that fan 60 rotates, the flowing of air is, as indicated by arrow B, first from below side by wind After the suction of fan 60, by passing through upward in the refrigeration cooler 24.

That is, the fan 60 is configured in the upstream side of the flowing of wind i.e. weather side relative to refrigeration with cooler 24.Thus, i.e., Make, in the case where refrigeration frost caused by cooler 24 disperses or evaporated, also to prevent moisture from flowing on fan 60.

Or in the case where configuring as shown in Figure 6 in cold duct 34, fan 60 can be configured and refrigerated With the upper side of cooler 24.Thereby, it is possible to prevent defrosting water from flowing on fan 60.In this case, side picks up from below Air, as shown by arrow, upward by but it is also contemplated that dispersing after refrigeration cooler 24 has been passed through Water droplet moved downwards by gravity, therefore flow to the possibility on fan 60 reduction.

Or as shown in Figure 7, the lower section even in refrigeration with cooler 24, as long as flow down area from defrosting water Domain (Rx) is the position of the substantially underface scope skew of refrigeration cooler 24, then it is considered that can prevent defrosting water from flowing to On fan 60.Now, fan 60 is configured to wind direction when with by refrigeration cooler 24 relative to refrigeration cooler 24 Opposite side.

It is in the case of fig. 7 to diagram left with wind direction during cooler 24 by refrigeration, therefore fan 60 is configured Than refrigeration with cooler 24 more by illustrate right side.Thus, even if the frost adhered on the surface of refrigeration cooler 24 Flown up due to wind, can also reduce the possibility flown on fan 60.

As long as in this way, flowing down outside region in defrosting water, then refrigeration cooler 24 can be configured in arbitrary position.Cause This, such as in figure 6, if in diagram left and right directions Existential Space, fan 60 can be configured in refrigeration cooler 24 Oblique upper etc..

In addition, as shown in Figure 8, refrigeration can flatly be configured with cooler 24 relative to the setting face of refrigerator 1.This Outside, level described herein, including be considered as the state of general horizontal, for example tilt some states.

By so generally horizontally configuring, the required space of short transverse can be reduced.Furthermore it is possible to match somebody with somebody along ceiling Put or can configure in heat-insulated segregated portion, therefore can increase case internal volume.

In this case, by the way that fan 60 is configured in the top of refrigeration cooler 24, thus, it is possible to prevent the water that defrosts Flow on fan 60.In addition, by as general horizontal, thus enabling that main part 24g increases and increasing surface area or make Main part 24g is thinned, thus, it is possible to realize the raising for setting the free degree, the reduction in required space.

In addition, wind direction is upward in fig. 8, i.e. from refrigeration with cooler 24 towards the direction of fan 60, from refrigeration with cold But the frost that device 24 is peeled off is moved downwards by gravity, therefore wind direction will not turn into problem.In addition, by making wind direction downward, i.e. Direction from fan 60 towards refrigeration with cooler 24, thus, it is possible to further suppress from the white attached of the stripping of refrigeration cooler 24 In fan 60.

In addition, it is so far, the cooler of so-called parallel type is illustrated with cooler 24 as refrigeration, but it is cold Tibetan cooler 24 can also use the cooler of snake formula as shown in Figure 9.The refrigeration cooler 24 of snake formula is formed To be connected to outlet from the entrance of refrigerant while 1 flat tube 24c is turned back.On flat tube 24c, freezing The entrance side of agent is provided with a 24a, and the outlet side of refrigerant is provided with a 24b.In addition, the flat tube 24c to be turned back it Between be provided with fin 24d.

Even the refrigeration cooler 24 of such snake formula, also with the cooling of the parallel type represented in first method Device is same, and heat exchange performance is higher, then can be significantly compared with the cooler of conventional fin-and-tube type if same performance Reduce its volume, and slimming can be turned into, therefore the free degree in configuration place can be improved, can obtain that storage can be used as The effective case inner volume that room utilizes.

However, as described above, refrigeration cooler 24 is, the refrigerant of liquid condition flows into, and is flowed out with gaseous state. Now, it is possible to produce the so-called time liquid (liquid back) that the refrigerant of non-evaporating completely is flowed out with liquid condition.

Therefore, the refrigeration of the parallel type schematically shown in Figure 10 (a) cooler 24, Figure 10 (b) are schematically The head 24b of outlet side volume can be formed larger than the head of entrance side by the refrigeration of the snake formula of expression with cooler 24 24a volume.In addition, Figure 10 schematically show due to head 24a is different from head 24b diameter and volume is different.

Thus, the head 24b of outlet side works as accumulator, can reduce the rear section side in refrigeration cooler 24 The worry that refrigerant is circulated with keeping liquid condition.As long as in addition, being able to ensure that enough volumes, no storage can be also realized Depressor.

In addition, on freezing cooler 25, the effect same with refrigeration cooler 24 can be also obtained.

＜ Third Way ＞

Hereinafter, reference picture 11 illustrates to Figure 13 to Third Way.In Third Way, to refrigeration cooler 24 The other examples of setting place illustrate.

In first method, rear that refrigeration cooler 24 is configured to the refrigerating chamber 14 in refrigerating chamber 3 is illustrated Example, but refrigeration cooler 24 can be also configured in other places.

For example, as shown in Figure 11, refrigeration cooler 24 can be configured and pushed up in the inside of refrigerator 1 and configuration Canopy side and be rear side (following, for convenience and referred to as top rear face side).Although also based on the size of refrigerator 1, refrigerator 1 Top rear face side be to take out hand when being put into food materials relative to refrigerating chamber 3 to be relatively difficult to the place that reaches.In addition, multi-streaming type is cold Tibetan is miniaturized as described above with cooler 24, therefore its required space also diminishes.

Therefore, by ensuring the space of refrigeration cooler room 36 in top rear face side, and configuration is refrigerated with cold in this place But device 24, thus, it is possible to effectively apply flexibly the more unapproachable place of hand.In addition, the rear side in refrigerating chamber 14 need not refrigerate With the space of cooler room 36, therefore refrigerating chamber 14 can be increased.

In this case, as shown in Figure 12, refrigeration cooler 24 and refrigeration blower fan 35 are set up in parallel (reference picture 5) and configure in top rear face side, free space thus can be formed at the rear of vegetable compartment 4 in the manner, because This can also make vegetable compartment 4 maximize.

In addition, as shown in Figure 13, refrigeration cooler 24 and refrigeration blower fan 35 are being set up in parallel (reference Fig. 5) configure in the case of the rear of refrigerating chamber 14, vegetable compartment 4 can be made to maximize.

In this way, by refrigeration with cooler 24 using multi-streaming type cooler, be thus not only refrigeration cooler 24, Configuration place, the free degree of configuration mode of refrigeration blower fan 35 can also be improved.Thereby, it is possible to will be difficult to food materials The top rear face side that is put into of taking-up effectively apply flexibly, by increasing capacitance it is possible to increase the effective case inner volume that can be utilized as storeroom. In addition, for freezing cooler 25, the effect same with refrigeration cooler 24 can be also obtained.

＜ ceiling configuration modes ＞

As described above, the refrigeration evaporator of multi-streaming type as cooler 24, if with conventional fin-and-tube type Cooler is in a ratio of same volume, then can expect 2~3 times of endothermic effect, on the other hand, if be only obtain with it is in the past same Deng endothermic effect cooler, then can realize miniaturization and slimming.That is, by using the evaporation of multi-streaming type Device, required installation space can be greatly reduced, it is relative thus, it is possible to the case internal volume that allows to utilize as storeroom Ground increase.

In addition, even if compared with the past can reduce installation space, nor installation space is said as zero, therefore in order that Case internal volume further increases, and where evaporator configuration is become into more important.The reason is that in order to be produced by evaporator Raw cold air supplies to storeroom and needs to arrange pipeline etc., thus by evaporator configuration from the position that storeroom separates When, the installation space increase of pipeline, case internal volume is possible to reduce on the contrary.

Therefore, in the manner, in view of the Land use systems of in general refrigerator, evaporator is configured to and is easier to turn into nothing With space and the increased position of installation space of pipeline can be suppressed.

Specifically, as shown in Figure 14, an example of the evaporator of multi-streaming type is the (reference of refrigeration cooler 24 Fig. 2, Fig. 9), be arranged on the ceiling side of refrigerator 100, and configure from the cool-air feed pipeline 37 suitable with rear duct forwards In the ceiling pipeline 101 of extension.The ceiling pipeline 101 is connected with cool-air feed pipeline 37, also, front side opening with it is cold Room 3 is hidden to connect.

Then, refrigeration cooler 24 is, including the profile for being relatively thin substantially rectangular-shape as general rectangular shape Its entirety including main part 24g, is configured in ceiling pipeline 101.That is, refrigeration with cooler 24 positioned at than cool-air feed pipe Road 37 on the front in the state of, configure in the ceiling side of refrigerator 100.

Under in general Land use systems, although also based on the size of refrigerator 100, the ceiling side of refrigerating chamber 3 and the back side Side is that hand is relatively difficult to the place for reaching therefore easily becoming wasted space when taking-up is put into food materials.In other words, refrigerating chamber 3 Ceiling side and rear side, be even if the convenience for being used, also being used with the installation space of cooler 24 as refrigeration The relatively low place of the possibility of deterioration.In addition, the ceiling side of refrigerating chamber 3 and rear side, certainly refrigerating chamber 3 extremely near, The pipeline that thus be accordingly used in cool-air feed also utilizes minimal installation space.

Then, shown in Fig. 2, Fig. 9 described above etc. like that, the refrigeration cooler 24 of multi-streaming type can turn into very slim Change.Now, when being thinned refrigeration cooler 24, if profile is identical, cooling performance reduces, but refrigerating chamber 3 Ceiling side can utilize the width identical length substantially with refrigerating chamber 3, so if needing then increase refrigeration cooling The width of device 24.Therefore, it is possible to avoid the situation of cooling performance deficiency.

In this way, the ceiling side of refrigerating chamber 3 and rear side, it may be said that be well suited to setting as refrigeration cooler 24 The place utilized between being empty.

Thus, by the way that the refrigeration cooler 24 of the evaporator of multi-streaming type will be used as, positioned at than being arranged on refrigerator 100 In the state of 37 side closer to the front of cool-air feed pipeline as rear duct of rear side, configure in the ceiling side of refrigerator 100, Thus, it is possible in the state of all immaculate for the both sides of manufacture side and user side, obtain storeroom being used as to utilize Effective case inner volume.

Now, can be configured to, from wall portion for example above ceiling pipeline 101, to main part 24g outer rim i.e. and main body Distance untill the position of the portion 24g opposite side of wall portion diminishes as far as possible.Specifically, can be by the master of refrigeration cooler 24 Body portion 24g is flatly set relative to setting face.Thereby, it is possible to the height for the above-below direction for reducing ceiling pipeline 101.

In this case, in refrigeration with the entrance side connecting portion being provided with cooler 24 for being connected with outside pipe arrangement 24e and outlet side connecting portion 24f (reference picture 2, Fig. 9), but these entrance side connecting portion 24e and outlet side can be connected Socket part 24f is arranged to horizontally extending from main part 24g.

Thereby, it is possible to reduce required length in the short transverse of installation space, the reduction of case internal volume can be suppressed. In addition, entrance side connecting portion 24e and outlet side connecting portion 24f can be from main part 24g along refrigerating chamber 3 width direction water Level land extends, and can similarly suppress the reduction of case internal volume in this case.

In addition, by making entrance side connecting portion 24e and outlet side connecting portion 24f than main part 24g more towards rearward, Thus, it is possible to which the distance of the fore-and-aft direction of cool-air feed pipeline 37 is utilized as into entrance side connecting portion 24e and outlet side connecting portion 24f configuring area.Thereby, it is possible to which refrigeration cooler 24 is configured at into more rear, although can be more effectively using being hand Unapproachable place but the space that can be utilized as refrigerating chamber 3.

However, for the cool-air feed into refrigerating chamber 3, fan 60 is provided with near cooler 24 in refrigeration.At this In mode, fan 60 is configured and matched somebody with somebody more closer to the front than refrigeration cooler 24 in the flowing of air in ceiling pipeline 101 Put in downstream.Now, fan 60 is configured as fan body turns into vertical, therefore can press down as horizontal, the i.e. flowing of air The height increase of ceiling pipeline 101 processed.

Now, contacted by the air circulated with refrigeration with the surface of cooler 24 to generate cold air.But will be cold , it is necessary to vertically pass through the air of the main part of refrigeration cooler 24 in the case that Tibetan is flatly configured with cooler 24 Flowing.Therefore, in the manner, in refrigeration with the upper side of cooler 24 and in rear end side, set to from cool-air feed pipe The obstruction part 102 that road 37 is hindered to refrigeration with the air flow of the upper side of cooler 24, also, cooled down in refrigeration The lower side of device 24 and in front, sets and the air flow for fanning 60 sides with the bottom lateral wind of cooler 24 from refrigeration is carried out The obstruction part 102 of obstruction.

Thus, from cool-air feed pipeline 37 to the leaked-in air of ceiling pipeline 101, due to the obstruction part 102 of upper side And the flowing of the lower side inflow to refrigeration cooler 24 is formed, also, formed and led to due to the obstruction part 102 of lower side Cross the main part 24g of refrigeration cooler 24 flowing.Thereby, it is possible to efficiently generate cold air.

In addition, in the case where main part 24g is flatly configured, flat tube 24c flat direction and fin 24d's Face direction, turn into the thickness direction i.e. vertical of the main part 24g described in Figure 14.In this case, when water droplet is attached to Flat tube 24c, fin 24d surface when, the water droplet is flowed down downwards by gravity.

That is, by the way that refrigeration cooler 24 to be configured to flat tube 24c flat direction relative to the setting face of refrigerator 100 Tilt or fin 24d surface tilts relative to the setting face of refrigerator 100, thus, it is possible to promote to be attached to refrigeration cooling The removing of the water droplet of device 24.Here, tilted relative to setting face, it is meant that be not horizontal state relative to setting face, also wrap Include the direction vertical with setting face.

However, when being defrosted to refrigeration with cooler 24, produce more water droplet and defrost water.Therefore, it is necessary to except White water to the mode of the convection current of ceiling pipeline 101, does not promote defrosting draining of the water from ceiling pipeline 101.Therefore, in the manner, Make below the ceiling pipeline 101 of the lower section of refrigeration cooler 24, after being refrigerator 100 towards the side of cool-air feed pipeline 37 Side, tilt downwards.In addition, with being integrally formed before cool-air feed pipeline 37 below ceiling pipeline 101.

Thereby, it is possible to promote discharge of the water from ceiling pipeline 101 that defrost.Now, supplied below ceiling pipeline 101 with cold air To being integrally formed before pipeline 37, therefore draining efficiently can be carried out to defrosting water.

In this way, as the draining promotion promoted in the draining for the water that defrosted to refrigeration caused by cooler 24 is defrosted Part, using the construction needed for cool-air feed i.e. ceiling pipeline 101, therefore construction can be simplified, and can pressed down The increase of manufacturing cost processed.

In addition, although so far illustrate refrigeration is configured in ceiling pipeline 101 with cooler 24 relative to setting Putting face turns into horizontal example, but also can be configured to make refrigeration with cold by refrigeration cooler 24 as shown in Figure 15 But device 24 tilts relative to the setting face of refrigerator 100.

In this case, the front end of refrigeration cooler 24 can be made to be located at side below ceiling pipeline 101, and make refrigeration It is located at side above ceiling pipeline 101 with the rear end of cooler 24.In this case, flat tube 24c flat direction and wing Piece 24d face direction is also arranged to the setting face inclination relative to refrigerator 100.

Therefore, from cool-air feed pipeline 37 to the air of ceiling pipeline 101, along flat tube 24c flat direction and Swimmingly flow in fin 24d face direction.That is, by by refrigeration cooler 24 be configured to the air flow that is passed through relative to The setting face of refrigerator 100 tilts, the circulation thus, it is possible to efficiently carry out cold air.

In addition, being located at by least a portion for being configured to main part 24g in ceiling pipeline 101, thus supply cold air Increase to pipeline 37 and ceiling pipeline 101 is exceedingly increased, it becomes possible to configure refrigeration cooler 24.That is, can press down The reduction of case internal volume processed.

In addition, by the way that refrigeration cooler 24 to be configured to tilt relative to the setting face of refrigerator 100, thus flat tube 24c flat direction and fin 24d face direction also tilt, therefore can promote to be attached to dripping for the defrosting water on surface. Now, tilted by being refrigerated as the manner with the rear end of cooler 24 in a manner of above, the water that thus defrosts is to cold The side of gas service 37 is dripped, therefore can also promote the draining from ceiling pipeline 101.

In the example shown in Figure 15, be configured to make from above ceiling pipeline 101 untill main part 24g outer rim Distance diminishes as far as possible, but the distance that can be also configured to from the back side untill main part 24g outer rim diminishes as far as possible.Tool It is the state for erectting refrigeration cooler 24 compared with Figure 15 state for body.In the case of such configuration, also can Access the above-mentioned various effects such as the effective case inner volume increase that can make to utilize as storeroom.

In addition, as shown in Figure 16, can not only by below ceiling pipeline 101, can also be by special tray 110 use as draining promoting member.In this case, tray 110 also rises as the part that stockpiles for temporarily stockpiling defrosting water Effect.Thus, it is not only to carry out draining to defrosting water, additionally it is possible to which defrosting water is effectively used in into so-called moistening control etc..

Now, tray 110 is by the length that is formed as covering refrigeration with the lower section of cooler 24, it is more specific and Speech, be formed larger than fore-and-aft directions of the main part 24g that is horizontal or obliquely configuring when being projected in vertical and The projection width of left and right directions, it becomes possible to which defrosting water is suitably stockpiled and discharged.Storage of the situation shown in for Figure 11 etc. Water receptacle 56 is similarly.
