Specific embodiment
With reference to specific embodiment, the technical solution of the utility model is described in further detail.
Present embodiments provide a kind of refrigerator realizing low frost effect, can effectively be lowered into the wet of air in casing
Degree, substantially reduces the frosting degree of refrigerator refrigerating chamber.Note：The reason refrigerator frosting also with the number of times of subscriber switch door body and time,
The humidity of the indoor object of freezing is relevant, and these are not talked about with user-dependent reason the present embodiment, only discusses and freezer structure
The reason design is related.
It is illustrated in figure 1 a kind of embodiment of described refrigerator, including the agent structure of refrigerator, such as casing 8, door body 1 and door
Envelope 2, compressor 7 and vaporizer 3.In order to realize heat insulation effect, using foaming door body and foaming box body, described foaming box body, send out
Bubble door body and the refrigerating chamber of door seal three formation opposing seal；Door seal can play part and stop moisture in air from entering refrigerating chamber
Effect.Described compressor 7 is located at below casing, for refrigerant compression is condensed into liquid, and with heat release.Described
Vaporizer 3 carries out heat exchange near the inner bag of casing, the liquid refrigerant of low temperature by vaporizer and extraneous air, and gasification is inhaled
Heat, realizes refrigeration, therefore nearby ambient temperature is relatively low for vaporizer.
The technical problem that freezing room pressure in order to solve refrigerator is low, freezing pressure outside is high, uses in the present embodiment
Refrigerating chamber is connected so that keeping pressure balance inside and outside refrigerating chamber by cold-trap pipe 4 with ambient atmosphere, reduces outside air and passes through door seal
Gap enters the probability of refrigerating chamber.Described cold-trap pipe is pre-installed between the inner bag 5 of casing and the outer wall of casing, and foams in casing
Interior, one end is gas outlet, connects with refrigerating chamber, and the other end is outlet, connects with outside air, and in described outlet just
Lower section setting evaporating dish 6.Because cold-trap pipe is near vaporizer, the low temperature being led to using liquid refrigerant gasification heat absorption in vaporizer
Environment, the moisture in cold-trap inner air tube was condensed into the globule before reaching refrigerating chamber, by action of gravity along cold-trap pipe
Tube wall, to dirty, is discharged in evaporating dish by outlet.
Described evaporating dish 6 uses as the container of water receiving, below compressor 7 top and casing, cold in cold-trap pipe
Solidifying water droplet is fallen in evaporating dish, and evaporating dish can absorb the heat of compressor release, and transfers heat to condensed water, makes condensed water
Accelerate evaporation.The structure of described evaporating dish is closed with compressor top matching form, including side wall and lower arcuate surface, described arcuate bottom
The centre in face raises up, surrounding concave downward, and condensing drip is fallen in evaporating dish, to surrounding landing.Described lower arcuate surface
Structure one side can make the top structure of evaporating dish laminating compressor, closer to thermal source（The i.e. heat of compressor release）, one
Aspect can increase the area of evaporating dish bottom surface, that is, increase the contact area of condensed water and thermal source, improves condensation evaporation of water speed
Degree.
As another kind of preferred embodiment, the lower arcuate surface of described evaporating dish is provided with conical surface screw thread, the section shape of screw thread
Shape can be triangle thread or saw-tooth thread, and thread depth is 0.5-1mm, can reduce the slip velocity of condensed water, increases
Plus condensed water and the time of contact of thermal source, accelerate evaporation rate.
Because refrigerator may need to run at different ambient temperatures for a long time, lead to evaporating temperature different, produced by vaporizer
Raw low temperature environment temperature unstable it is impossible to ensure not freeze, in order to ensure normally running and playing of cold-trap pipe in cold-trap pipe
The effect of low frost, the temperature of precise control cold-trap pipe, the described refrigerator realizing low frost effect also includes temperature-controlling module, specifically
Including temperature sensor 9, heater 10, dew point transducer 11, it is connected with controller 12 respectively.Described temperature sensor 9, plus
Thermal 10 is located on the outer wall of cold-trap pipe 4 gas outlet one end, and described dew point transducer 11 is located at cold-trap pipe 4 outlet one end
On outer wall.The signal of temperature sensor and dew point transducer collected by described controller 12, according to program set in advance, to heating
Device sends and opens（on）Close（off）Order, controls temperature in cold-trap pipe to be more than 0 degree and is less than dew point temperature, reach good condensation
Effect, finally makes direct-cooled refrigerating appliance realize low frost.
The vertical dimension apart from cold-trap pipe gas outlet for the described temperature sensor is 200mm-300mm, accurately measures this position
Temperature, simultaneously by described heater be arranged on apart from cold-trap pipe gas outlet vertical dimension be 300mm-400mm position on,
Implement heating in this position, precision ice can be ensured, it is to avoid cold-trap pipe is blocked by ice, heat can also be avoided to be passed to refrigerating chamber
Interior, cause energy loss.Described heater can take various forms, it is possible to use heater strip is fastened in cold-trap tube wall
On face, or it is attached on cold-trap tube wall using glass heating tube.
The present embodiment can with effectively solving cold-trap pipe temperature too low and freeze problem, using intelligent temperature control assembly,
Adjust the temperature of cold-trap pipe by heater, keep temperature stabilization in cold-trap pipe it is ensured that moisture in air is condensed, and can prevent
Only freeze in cold-trap pipe.
If cold-trap pipe distance vaporizer is too remote, in cold-trap pipe, low temperature can not be formed, if cold-trap pipe distance vaporizer is too near,
Cold-trap pipe interior temperature is spent low, needs frequent starting heater, increases energy consumption, therefore, between described cold-trap pipe and inner bag away from
From 2/5-3/5 for tank thickness when, it is possible to achieve compared with low energy consumption.As a kind of preferred scheme, described cold-trap pipe is in foaming
At casing 1/2 thickness, the casing of for example current refrigerator commonly used 70mm foam thickness, cold-trap pipe is vertically disposed in apart from inner bag
At 35mm.
According to the size of freezer box volume, the internal diameter of described cold-trap pipe is 6-12mm, and pipe thickness is 0.5-1mm, makes
The tension force that the globule must be condensed is less than gravity, and the globule will not take whole caliber and affect unimpeded in cold-trap pipe.It is further preferred that
The higher TP2 M state copper pipe of the material selection coefficient of overall heat transmission of described cold-trap pipe, or band thermal shrinkable sleeve coating steel pipe.
Above example is only several in the several preferred implementation of this utility model it is noted that this practicality is new
Type is not limited to above-described embodiment；For the person of ordinary skill of the art, still can be to described in previous embodiment
Technical scheme is modified, or carries out equivalent to wherein some technical characteristics；And these modifications or replacement, do not make phase
Answer the spirit and scope of essence disengaging this utility model technical scheme required for protection of technical scheme.
