In addition, the lower limb of the lower edge specific surface plate 88 of backplate 86 is positioned at the top slightly, and with the angle at inclination angle of imitation evaporating dish 41 to the upper left inclination of seeing from the back side.And, seeing on the lower limb of this backplate 86 from the back side keep right the position upper cut of end form embed above-mentioned drainpipe 33 and dodge dodge recess 89.
On passage 85, install panel 95 on the opening.Top panel 95 has the size that roughly conforms to the top opening size of passage 85 as shown in figure 11, and the slit 96 on the fore-and-aft direction is provided with a plurality of along the left and right directions arrangement.Form downward installing plate 97 with sharp bend on the leading edge of plate 95 in the above, and form the small size plate 98 that erects with same sharp bend, form to the inboard from the top edge that erects plate 98 again and prolong the insertion plate 99 of coming out obliquely upward in back edge.Have again, the formation zone of the exhaust outlet 28 on the rear board 14B of Machine Room 14 just under the position on form and insert plate 99 insertable insertion grooves 100.
Cover 105 is metal systems, as Fig. 4, shown in Figure 15, is the shape that the flat ware of the direction of rear side opening erects, and can cover the almost whole of above-mentioned evaporating dish 41 and passage 85.From cover 105 about and the edge of opening of downside form installing plate 106 respectively with stretching out, and in the above plate 107 upper cuts form that the upper edge of passage 85 embeds and dodge dodge recess 108.
And, cover 105 fixes in the following manner: promptly, dodging the top edge that is embedded with passage 85 on the recess 108, butt in from the back side 10A of refrigerator main body 10 to the scope of the lower limb of rear board 14B, thus be screwed into fixed cover 105 in the screwed hole 112 of correspondence position of back side 10A of refrigerator main body 10 by screw 110 spirals at the patchhole 111 of each installing plate 106 upper shed.Thus, the patchhole 83 usefulness cover 105 of the almost whole and lead 63 of evaporating dish 41, passage 85 etc. covers, and on the other hand, the top panel 95 of passage 85 is in the state that opens wide up.
Then, the effect to present embodiment describes.
In refrigerator work, the running if defrost, flow out from the drainpipe 30 of inboard and draining cylindrical shell 32, drainpipe 33 after then accepting with drain pan 20, flow down from discharge outlet 35 again in the lower aperture of drainpipe 33 front from the defrost water of cooler 25 grades.Owing on the positive upper/lower positions of discharge outlet 35, be furnished with shield 80 with front end posture down, so the defrost water that flows down from discharge outlet 35 shown in the arrow X of Figure 14, is mainly dripped and is stockpiled bottom at evaporating dish 41 from its front end after accepting with shield 80.Because evaporating dish 41 is installed with the posture that tilts, so so that dark more mode stockpiles to the right side more.
Meanwhile, evaporation is switched on heater 60, the water (defrost water) that stockpiles that stockpiles in evaporating dish 41 is heated also forced evaporation, and steam rises.Here, especially the steam that rises from the position corresponding to the below of drainpipe 33 might flow into cooler chamber 21 sides from drainpipe 33, but owing to below discharge outlet 35, be furnished with shield 80 as mentioned above, so shown in the arrow Y of Figure 14, steam crested plate 80 covers and is driven away the left of drainpipe 33, and the steam that rises with the left sides in evaporating dish 41 rises in passage 85, discharges upward by the slit 96 of top panel 95.Even the part of steam is back to the below of drainpipe 33 and flows into from discharge outlet 35, because the position upper shed of just going up in discharge outlet 35 is provided with discharge port 36, so shown in the arrow Z of Figure 15, flow into the steam of coming in from discharge outlet 36 and continue to rise and discharges upward, rising and passage 85 in similarly from slit 96 discharges from discharge port 36.Thus, place steam more reliably from drainpipe 33 adverse currents.
Have again, the part of the steam that ejects above passage 85 is by contacting and dewfall with the rear board 14B of Machine Room 14, this dew might flow down along this rear board 14B, but dew is accepted with insertion plate 99 and is flowed on the top panel 95 of passage 85, and profiling its be tilted to inboard flowing, stockpile once more in evaporating dish 41 from slit 96 and edges at two ends, be used for evaporation.
When the defrosting running finishes, then begin to cool down running once more, but condenser fan 17A running this moment, cooling sucks cooler condenser 17 and even compressor 16 with extraneous gas from the front side, and the exhaust outlet 28 of the used heat that is used to cool off rear board 14B of 14 from the Machine Room is discharged to rear side.Thus, the steam that ejects upward from the top panel 95 of passage 85 with the low concentration diffusion, has the occasion of wall in the room in kitchen etc. owing to be subjected to used heat nearby, also can avoid avoiding concentrating a large amount of steam and dewfall due to contacting at this.
At evaporation heater 60 fb durs, evaporating dish 41 self also is heated and heats up, but the perisporium (the edge of opening 42A of flange 49, main part 42) of the thin-walled around the only recess 55 at the back side of evaporating dish 41 is connected on the back side 10A of refrigerator main body 10, we can say and not only be in toe-in pencil attitude, and by being provided with above-mentioned recess 55, thereby and the back side 10A of refrigerator main body 10 between form air layer A and play a role as heat insulation layer, so the heat of evaporating dish 41 is difficult to pass in the case.Thus, can prevent unnecessarily temperature rising in the case, otherwise in addition, also can suppress evaporating dish 41 temperature and reduce, reduce so also can prevent to stockpile the evaporation of water ability.
When evaporation is carried out, the water level that then stockpiles water reduces gradually, but because evaporating dish 41 is installed with upper left posture, so always be in the most shallow state of left side one end, therefore, when evaporating again, then from evaporation with the front of the transverse part 62 of heater 60 successively to stockpiling the impregnation state liberation of water, carry out the temperature rising rapidly.After thermostat 73 detects set point of temperature, think that then the surplus that stockpiles water for a small amount of, stops the energising of evaporation with heater 60.Promote the left evaporation of water that stockpiles by the waste heat that evaporates with heater 60 after this a little while.
In this wise, because evaporating dish 41 is installed with inclination attitude,, stockpile the result that the withered position of water is offset from left to right gradually so obtain at its base plate.For example place right bank or little ladder are being set, refrigerator can only also can obtain identical effect with the occasion of the posture setting of seeing upper right slightly inclination from rear side.And, the place of the close extreme higher position in its bottom more specifically, at first detect to the evaporation of the impregnation state liberation that stockpiles water temperature with the front of the transverse part 62 of heater 60, cut off evaporation heater 60, so most transverse part 62 stops heating under impregnated in the state that stockpiles in the water, suppress so-called dry combustion method as far as possible.
In the occasion of cleaning in the evaporating dish 41, take off cover 105 and passage 85 after by the screw 52 of loosening, thereby take off evaporating dish 41.Thereafter, when taking off carriage 65 together and evaporating, then because the inside of evaporating dish 41 is in the state of top opening, so can wash cleaning inside until each corner with heater 60.About covering 105 and passage 85, take off similarly and also can wash.
The effect of present embodiment is as follows.Carry out fb dur in evaporation with heater 60, evaporating dish 41 self also is heated and heats up, but the back side of the evaporating dish 41 only perisporium (the edge of opening 42A of flange 49, main part 42) of recess 55 thin-walled on every side is connected on the back side 10A of refrigerator main body 10, can be described as and be in the line contact condition, and by above-mentioned recess 55 is set, thereby and the back side 10A of refrigerator main body 10 between form air layer A and as heat insulation layer performance function, so the heat of evaporating dish 41 is difficult to be delivered in the case.Thus, can prevent unnecessarily temperature rising in the case, in addition, otherwise, reduce so also can prevent to stockpile the evaporation of water ability owing to also can suppress the reduction of evaporating dish 41 temperature.
Evaporating dish 41 is by forming with solder joints main part 42 and back side liner plate 48, liner plate 48 dual-purposes in the back side form recess 55, and make the shape that is provided with at the crooked rectangular flange 49 of circumferential edges, this flange 49 is embedded on the edge of opening 42A at the back side of main parts 42 and weld, so compare with the structure of the flat board that does not have flange 49, carry out the location of back side liner plate 48 easily, can successfully carry out ensuing weld job, and can carry out the manufacturing of evaporating dish 41 with the short time.
