Bottom illustrates its action.By cooler 18 chilled cold air, carry by ice chest fan inside 20, blow to 2 li of refrigerating chambers, cool off this refrigerating chamber.And a part of cold air in the above-mentioned cold air, the supply passageway 13 through to refrigerating chamber 3 cool-air feeds directs into cold gas exhausting outlet 13a, and the damper humidistat 14 control air conditioning quantity by being contained in the there make the temperature (3 ℃) that is cooled to stipulate in the refrigerating chamber 3.
On the other hand, the another part in the cold air through the cool-air feed path 15 of shunting usefulness, flows through at the upper surface of the end face cold drawing 16 that is made of porous material, passes through the outer peripheral face of Quench box 7 and the cold air path 19 of its outer peripheral face subsequently, is discharged in the refrigerating chamber 3.
Like this, because the cold air of supplying with flows through the surface of end face coldplate at first, and makes it can reach minimum temperature, just can not be too low and constitute the temperature of the inner bottom surface of Quench box 7 of built-in food placed side and inner peripheral surface, therefore built-in food just can not freeze.In addition, owing to formed the above-mentioned airtight low temperature chamber 5 and the closed structure of closing by common lid 8 in the open front of the Quench box 7 of its inside, some moisture content that are evaporated from food can make maintenance high humility in the Quench box 7, again can be as shown in Figure 3, the water evaporates of food is suppressed, can keeps the freshness of food.
In addition, be to constitute because temperature drops to minimum end face coldplate 16 with the porous material that can keep moisture content, the moisture content that evaporates in inside can be retained in its body, and the globule that also can not condense on other parts.
Fig. 4 is expression embodiments of the invention 2 figures suitable with Fig. 1, the refrigerating and cold storage refrigerator of this embodiment, installing damper thermostat 14 at the cold gas exhausting outlet 13a that leads to the cool-air feed path 13 in the refrigerating chamber 3 from cooler 18, enter in the above-mentioned cooling air passway 17 by cool-air feed path 15 by the part in the cold air of these thermostat 14 controls, end face coldplate 16 along Quench box 7 flows, directly turn back in the A of cooler chamber by the cold air return path 37 that leads to cooler 18 again, like this, Quench box 7 just begins to be cooled independently from end face.
At this moment, because the front openings portion of low temperature chamber 5 and Quench box 7 is by lid 8 closures, and the top of Quench box 7 is by end face coldplate 16 closures, and the cold air by cooling air passway 17 does not directly enter in the Quench box 7, so can keep high humility in the Quench box 7.
Fig. 5 and Fig. 6 are the refrigerating and cold storage refrigerator major parts of expression embodiments of the invention 3, promptly are arranged on the Quench box 7 in the above-mentioned airtight low temperature chamber 5 and the zero deflection installation diagram of its end face coldplate 16.Among the figure, identical symbol is all put in identical with Fig. 2 or suitable place, and has omitted the repeat specification to them.In the drawings, the 30th, upper frame, on it, overlap the end face coldplate 16 of laying Quench box 7, and form the cooling air passway 17 that is communicated with of cool-air feed path 15 with shunting usefulness between the lower surface by end face coldplate 16 and spaced walls 4, by rear portion rib 32 in accordance with regulations the height of hinged joint 31, be fixed on the rear wall back side of Quench box 7 along the below prolongation of figure with overlapping.The 33rd, the outstanding framework in rear portion that constitutes with 32 one-tenth delegation of above-mentioned rear portion rib, it with above-mentioned rear portion rib 32 between form the cold gas exhausting outlet 34 that is communicated with above-mentioned cooling air passway 17, the rear end face that framework 33 is given prominence at the rear portion docks and is fixed on the rear wall inner surface of above-mentioned low temperature box 9.
So, the outstanding framework 33 of above-mentioned upper frame 30 and rear portion is contained in the low temperature box 9, end face coldplate 16 is installed on the upper frame 30, the feature that forms the only cold air path 19 that leads to refrigerating chamber 3 around Quench box 7 and end face coldplate 16 is so just arranged.
Fig. 7 and Fig. 8 represent embodiments of the invention 5, and it is made the end face coldplate 16 of Quench box 7 easily and freely loads and unloads in airtight low temperature chamber 5.Wherein identical with Fig. 5 or suitable place is all used with a kind of symbolic representation, and has omitted the repeat specification to them.This embodiment of the present invention is arranged on above-mentioned end face coldplate 16 in the airtight low temperature chamber 5, the cold air of being supplied with by cooler 18 is limited in is communicated with cooling air passway 17 above the end face coldplate 16, in the scope of the upper opening size of the sizable Quench box 7 of the end face coldplate 16 of Quench box 7, by being embedded in the ring-shaped frame 35 on end face coldplate 16 peripheries, can be connected to above-mentioned end face coldplate 16 on the upper opening part of above-mentioned low temperature box 9 with freely loading and unloading, thereby between Quench box 7 and low temperature box 9, form the cold air path 19 that communicates with above-mentioned cooling air passway 17 towards refrigerating chamber 3, with the outstanding rib 36 that is provided with on the lower surface of spaced walls 4, push this end face coldplate 16 with the top, prevent to come off because of carelessness.Employed end face coldplate 16 needn't contain Deodorizing catalyst and antiseptic in the refrigerator of the above embodiments 4, embodiment 5.
With reference to accompanying drawing 9 embodiments of the invention 7 are described.In this embodiment, the hydrophilic porous sintering resin material that is made of the upper strata 16a of the 16b of lower floor of low temperature chamber 5 one sides and cooling air passway one side of end face coldplate 16 forms.Wherein, because higher temperature is handled when using than the 16b of sintering lower floor, material is fusion by heating, and material is more approaching, and the porosity is diminished, thereby forms the upper strata 16a of less cold air passage one side of the ratio (porosity) of pore 16c.Since the minimum end face coldplate 16 of temperature be with lower floor have suction, the function of preserving moisture; The hydrophilic porous material sintering resin that the upper strata has the damping function forms, and therefore, even under the high humility situation more in the food preservation amount, that moisture content evapotranspires more, the pore 16c of lower floor can absorb moisture, does not sweat thereby can not condense.This is that the food preservation amount is big, fully sets the situation that absorbs moisture, moisture-retaining capacity.On the contrary, when the food preservation amount after a little while, moisture can absorb, but owing to use Temperature Treatment higher when baking, and makes near the pore 16C of the top section of cooling air passway one side fewly, thereby at reserve capacity after a little while, moisture is emitted less, can keep high humility in the low temperature chamber 5.Hydrophilic porous sintering resin handlebar moisture is retained in the effect in the pore.
In order to make low temperature chamber one side that is easy to become high humility, Ning Ju the globule is not fallen on the food thereon, therefore is necessary to make this side to keep moisture easily.On the contrary, less at load, difficulty becomes under the situation of high humility, and pore can reduce airtight degree, makes food drying easily.Therefore, the surface of cooling air passway one side, especially because of contacting with cold air, it should can keep the sintering resin of moisture to form with pore less, prevents water evaporates thus, adjusts temperature.Moisture not to keep, just do not have with the psychrometric difference of cold air, and also just difficult evaporation, if moisture is many, also just evaporation (damping function that Here it is) easily.
The above embodiments are when sintering, the sintering temperature that makes one deck is than another floor height, control the pore 16C of levels thus, but also can be as shown in figure 10, pore 16C above formation secondary operations face 38 reduces on end face coldplate 16, for example hot pressing is processed, is sprayed paint, adhered film etc.
Because the Temperature Distribution difference of end face coldplate 16 in the many places of part water absorption, by adjusting the range of work of secondary operations face 38, can increase the water discharge of part.
Below, Figure 11, Figure 12 are expression embodiments of the invention 7 figures suitable with Fig. 1, Fig. 2.Among the figure 22 is contained in the Defrost heater that spaced walls 4 following above-mentioned end face coldplates are used with overlapping, as shown in figure 13, it is connected side by side with the Defrost heater 21 that above-mentioned cooler is used, every certain time, drive with relay contact 25,26 connections by each by each time device 23,24 calculating.When defrosting end temp sensor 21a, 22a reach uniform temperature when above, above-mentioned driving is disconnected with relay tip 25,26, the defrosting end of cooler 18 and end face coldplate 16.Number in the figure 27 expression power supplys.
In the above embodiments, the defrosting of the defrosting of end face coldplate and cooler is carried out independently.Figure 14 is that the Defrost heater 21 that Defrost heater 22 that the end face cold drawing uses and cooler are used is synchronous, with the driving relay contact 25 of Defrost heater two above-mentioned heaters 21,22 are connected with a cooler, when reaching more than the uniform temperature, cooler defrosting end temp sensor 21a disconnects two heaters 21,22.
Figure 15 is another embodiment, and it is a bimetallic shape switch 28 of installing temperature recovery type around end face coldplate 16, and when the temperature in end face coldplate 16 and the airtight low temperature chamber 5 too rose, just the Defrost heater 22 that the end face coldplate is used disconnected.
Because above-mentioned Defrost heater 22 is installed in especially near near sending the outlet of cold wind toward cooling air passway 17, because of this part temperature is minimum, thereby icing easily problem also is resolved, thereby just can defrosts equably.
Because the refrigerator of embodiment 8 is made above-mentioned structure, part in the cold air is through the cool-air feed path 15 of shunting usefulness, on the end face coldplate 16 that constitutes by porous material and contain Deodorizing catalyst and antiseptic, flow through, pass through the outer peripheral face of Quench box 7 and the cold air path 19 of its outer bottom subsequently, be discharged in the refrigerating chamber 3, just can not mouldy and stink in the therefore airtight low temperature chamber 5.
And the decomposition reaction by the Deodorizing catalyst in the end face coldplate 16 causes can be promoted as illustrated in fig. 17 by the above-mentioned heater 22 that is provided with facing to the end face coldplate.On the other hand, worry that airtight low temperature chamber 5 internal cause humidity are high and this point that mildews has also been solved by antiseptics contained in the above-mentioned end face coldplate 16.In addition, heater 22 is switched on termly again by timer 23, thereby just can not cause that temperature rise in Quench box 7 and the airtight low temperature chamber 5.
