Abstract
There is the refrigerating appliance of that surround storage chamber, heat insulation housing (2,3), especially in Domestic refrigerator, on the crust of described housing, the section (6,9 of refrigerant pipe, 11) be arranged at least two planes, and connect abreast in flow technique.
Description
The present invention relates to a kind of refrigerating appliance, especially Domestic refrigerator, this refrigerating appliance has the heat insulation housing surrounding storage chamber, and in this housing, condenser is integrated in the crust of housing.Such evaporimeter is also known with side plate condenser (Skin-Verfluessiger).
This refrigerating appliance generally includes internal container, at least partly by crust, the refrigerant pipe that is enclosed in the spacer material layer between internal container and crust and extends between crust and spacer material layer on the inner side of crust of sheet material forming.
The refrigerating appliance with such side plate condenser does not have particularly preferred efficiency usually, because outwards not distributed from utensil by the part being in the heat discharged in close thermal contact with spacer material layer by condenser, and be through spacer material layer and flow back in storage chamber.
In order to minimize such backflow, the temperature of condenser must keep low as far as possible.But still realize required heat radiation power in order to although condenser temperature is low, need large condenser area.Therefore propose, side plate condenser is arranged be distributed on multiple walls of refrigerating appliance.But have problems at this, that is, the refrigerant pipe crossing over the part at the turning of formation refrigerating appliance body not between homonymy of crust tends to narrow as shown in WO2008/077699A1.Transition part between condenser and evaporimeter wishes such narrowing, and between the entrance and exit of condenser, the compressor horsepower that causes needs high on the one hand owing to the one or more this Pressure Drop that narrows is with circulating refrigerant, on the other hand, the adiabatic expansion of cold-producing medium causes cooling in such stenosis, and consequently the region being positioned at such stenosis downstream of condenser is almost helpless to hot exchange power.
A kind of alternative is, the multiple condenser elements be arranged on outside refrigerating appliance body one are one another in series connection.Because these condenser elements must be assemblied in substantially equal height, to make full use of operational surface, only have when each independent element comprises the pipe section rising in the flowing direction and decline, such serial connection is only practical.This causes the cold-producing medium of condensation to be gathered in the local bosom of condenser and the cold-producing medium being still gaseous state must be through fluid extracts out.When environment temperature is low, if the liquid refrigerant ratio in condenser is relatively high, then therefore need the cold-producing medium of larger loading, liquid refrigerant to be pressed onto against gravity the outlet of condenser.Gaseous refrigerant in a liquid to rise bubble can cause produce interfering noise.This continues the relatively long time, has liquid refrigerant available until connect compressor on condensator outlet.Off-energy in each off-phases of compressor, because liquid refrigerant remains within the condenser and is not made land used evaporate or even discharge from evaporimeter when liquid refrigerant evaporates within the condenser.
Task of the present invention realizes a kind of refrigerating appliance, this refrigerating appliance have extend on the crust of apparatus shell, as the refrigerant pipe of condenser, it can provide liquid refrigerant and/or the interference noise in running minimized with little delay.
This task is solved by such mode, namely, at refrigerating appliance, especially in Domestic refrigerator, this refrigerating appliance has that surround storage chamber, heat insulation housing, in this housing, the section of refrigerant pipe is arranged at least two planes by the crust of housing, the section be arranged in Different Plane connects abreast in flow technique.Such structure allows both to avoid there is undesirable slype between the section of mutually following of refrigerant pipe, also avoids mutually following of rising section and decline section.
It is suitable that, the different walls of different plane difference corresponding housing, that is, the section be arranged in Different Plane is arranged on the different exterior faces of housing.
These exterior faces at least should comprise a rear wall and a sidewall of housing, preferably include a rear wall and two sidewalls.
Each section of refrigerant pipe is preferably placed on a flat board.Two this plates can each other in engaging squarely.
But also can be that one block of unique plate comprises at least two parts linked into an integrated entity along sweep, arranges a section of refrigerant pipe on these parts respectively.
The each this section of refrigerant pipe preferably includes a upstream portion substantially upwards extended as the crow flies to top from the crosspoint that these sections are common and one and goes back to bent the downstream part to downward-extension from top point.
These sections of refrigerant pipe can meet on the dryer or on choke valve.
Being arranged in parallel of these sections allows for these sections and uses the conduit with relatively little cross-sectional area respectively.In common condenser, the cross-sectional area of conduit is about 10mm usually
2, and in refrigerating appliance according to the present invention, in each section of conduit, cross-sectional area is less than 5mm
2just enough.
Other features and advantages of the present invention, with reference to accompanying drawing, are drawn by the following explanation of embodiment.Accompanying drawing illustrates:
