In Figure 10, show a refrigerator 70 with front view, the door body has been removed.Refrigerator 70 has a single evaporator coil 71, and it has heat exchange fin 72 and water receiving tank 73.Insulator 74 has formed the outside of refrigerating chamber 75, is usually closed by a traditional door (not expressing).Refrigerating chamber 75 as shown in the figure comprises ice chest 76.The top of refrigerating chamber 75 is open, and therefore the cold air from refrigerating chamber 75 can flow freely into refrigerating chamber 77.
Of the present invention preferential embodiment shown in Fig. 1 and the 1a has the economy of use and low cost of manufacture.When operation, during the compressor operating, as shown in Figure 1, refrigerant arrives evaporimeter 22 traditionally.Evaporimeter 22 is in refrigerating chamber 15 tops towards the top of refrigerator 10, and near refrigerating chamber 25.Evaporimeter 22 cooling ambient airs, air along the path flow channel 27 of drip tray 17 and by passage 30, are entered refrigerating chamber 15 by dividing plate 28 guiding by convection current.When cold air by opening or sealing 24 on the insulation wall 29, cold air enters refrigerating chamber 25.
Preferably sealing 24 is made into narrow and has gradient upwards as shown in FIG..
The gradient that makes progress of sealing 24 and make the cold air that narrow helping limit big flow and enter refrigerating chamber 25 is because this refrigerated compartment 25 inadequately.From refrigerating chamber 15 than wink air guided by dividing plate 28, be recirculated to evaporimeter 22.
Shown evaporimeter 22 has traditional heat exchange fin 23 to increase its cooling capacity.
Fixed dam 1a regulates from refrigerating chamber 25 and crosses drip tray 17 to the entering of evaporimeter 22, and receives warm convection current air from refrigerating chamber 25, and by evaporimeter 22 circulations.
Fig. 1 a display refrigerator 10 is at compressor duration of work not.When compressor duration of work not, from the warm air of refrigerating chamber 25 since convection current cross fixed dam 19 and cycle through evaporimeter 22.Warm air is cooled to evaporator defrost and in this process.Chilled air flow channel 27.Basically the air of all coolings flows into refrigerating chamber 25 by sealing 24.Defrost cycle is proceeded normally to start kind of refrigeration cycle until traditional constant temperature system (not shown).
Fixed dam 19 is regulated traditionally, only abides by the normal atmosphere pressure of refrigerator 10 settlements and regulates, and has avoided using more complicated adjusting system like this.
Cold air in the refrigerating chamber 15 plays a part the pond basically, and convection current occurs in the top in pond basically.Like this, during defrosting, warm defrost air trends towards staying in the top in cold air pond, and can the article in the refrigerating chamber 15 not thawed when duration of work is when evaporimeter 22 quilt defrostings at compressor 13.
By evaporimeter 22 being arranged at refrigerating chamber 15 tops, all separate with refrigerating chamber 15 and refrigerating chamber 25, one air stream that flows to refrigerating chamber 15 and refrigerating chamber 25 can be held, tube compressor 13 is not during work or inoperative, can make keep required temperature in refrigerating chamber 15 and the refrigerating chamber 25 and can not make in the refrigerating chamber 15 take place unsuitable thaw or refrigerating chamber 25 in cold excessively.
Identical with refrigerator 10 haply as Fig. 5,5a, but be provided with passage 41 and 42 with the refrigerator 40 as shown in 6, so that at compressor 13 work and duration of work guiding air stream not.Passage 41 to refrigerating chamber 15 openings and accept to leave refrigerating chamber 15 and along the arrow A direction move than warm air circulation.The top of passage 41 is positioned at the height of the opening of centre gangway 42.Like this,, be moved down into the zone of drip tray 17, flow directly into refrigerating chamber 15, as shown by arrow B by the air that evaporimeter 22 cools off.Each passage 41 cross-over connection evaporimeter 22, so they do not disturb the cold air circulation by passage 42.The cold air that arrives refrigerating chamber 25 can see that mainly by sealing 24 sealing 24 is levels in Fig. 6, crosses most of width of passage 42.
No matter should remember work or null cycle at compressor reducer 13, in passage 42 or the air in the path 30 of the refrigerator 10 of Fig. 1, come compared with the air in the refrigerating chamber 25, all be colder and heavier, like this, there is a trend to make cold air extract out and enter in the warm refrigerating chamber 25 through sealing 24.
Adjustable baffle plate 43 can be controlled by bellows, as shown in Figure 5, when compressor 13 duration of works, 22 enter and be restricted from refrigerating chamber 25 to evaporimeter.Bellows is to the thermotonus sensitivity of refrigerating chamber 25, and the temperature in refrigerating chamber 25 raises and just opens.At the not duration of work of compressor 13, adjustable baffle plate is in bigger open position, increases the warm air flow that comes out from refrigerating chamber 25, to help the defrosting of accelerating evaporimeter 22.
Adjustable baffle plate 43 is positioned at refrigerating chamber 25.There is one warm air to flow through this adjustable baffle plate 43.Therefore this adjustable baffle plate 43 can not be frozen and lose efficacy.This adjustable baffle plate 43 does not need to protect with any heating mechanism.
At compressor 13 duration of work not, as shown in Fig. 5 a, have only seldom or do not have warm air circulation from refrigerating chamber 15 these air ponds, during the part defrosting, pass through the cold air of evaporimeter 22 simultaneously, admission passage 42 also continues to cycle through sealing 24, to keep the temperature of refrigerating chamber 25.
As shown in Figure 7, air is along the arrow A direction passage 41 of flowing through, and gets back to refrigerating chamber 15 along the arrow B direction by passage 42.Drip tray 17 is gradient, so all defrosting water droplets are pooled to and reach drainpipe 18, therefore can discharge fully.
As shown in Figure 9, refrigerator 60 is provided with vertically arranged evaporimeter 61, and normally the aluminum composite plate material is made.Drainpipe 62 is placed in the below, bottom of evaporimeter 61 to accept all defrosting water droplets.Refrigerator 60 is being provided with a fixed dam 63 and opening 64 as the warm air import from refrigerating chamber 25 admission passages 27.Dividing plate 65 is used for controlling the air stream from refrigerating chamber 15.Because evaporimeter 61 is in fact to be in refrigerating chamber 15 tops, the air in refrigerating chamber 15 is still kept as the pond state, keep effectively compressor 13 not duration of work can not thaw.Enter refrigerating chamber 25 by sealing 24 under the cold air normal condition in passage 27, as shown in other embodiments like that.
The circulation air enters refrigerating chamber 77 and is mainly caused by the cold air overflow of refrigerating chamber 75, as shown by arrows, works as not duration of work of compressor 13 especially, from the warm air circulation process evaporimeter 71 of refrigerating chamber 77, to evaporator defrost.Still maintain the top in cold air pond from the warm air at top, refrigerating chamber 75 cold air pond.In a special embodiment, in refrigerator 70, there is the part of closely similar ice cube to thaw on the top of refrigerating chamber 75.Thawing of this surface is not a matters of aggravation for ice cube.At the frozen goods of refrigerating chamber 75 bottoms owing to be in the cold air pond dearly, even compressor reducer 13 not duration of work the surface can not take place yet thaws.Evaporimeter 71 preferably has fin 72, and its guides defrosting water droplet into rhone 73, and refrigerating chamber 77 is being protected in thicker insulation 74, makes it can be not cold excessively at compressor 13 duration of works.Thicker insulation 74 has prevented that also refrigerating chamber 75 is owing to the heat from refrigerating chamber 77 thaws.
In order to carry out better freezing, recommend evaporimeter and suddenly freeze the food chamber to separate effectively, also the insulation of available dedicated is around the refrigerating chamber space.
System of the present invention can be used for any cooling module that places the refrigerating chamber top equally.Freezing is not must be from an evaporimeter, and compressed refrigerant neither be from a compressor.The effect of native system is from the flow problem of air when refrigeration work and the null cycle.Like this, new-type refrigerating plant null cycle its evaporimeter defrosted the samely.
Title herein and noun just are used to lay down a definition, and should understand and can also make various remodeling.
Be understood that also following claims are intended to topped the present invention in this all main points and feature of saying, the scope of declaring of the present invention also drops on wherein in the nature of things.
