Abstract
The utility model relates to a door sealing structure for a refrigerator and a freezer, which mainly and structurally comprises a box body, a door body and door seals arranged between the box body and the door body, wherein two door seals are arranged on the door body and are mutually sealed, so an air temperature isolation layer is formed between the two door seals. The edges of both the door body and the box body are in a step shape, and in addition, the step shape of the edges of the door body is matched with the step shape of the edges of the box body. When the door body of the refrigerator is closed, an air chamber of the second door seal is extruded between the door body and the box body, and a passage between a refrigerating or freezing chamber and the first door seal is completely cut off, so a sealing space with the temperature difference can be easily formed between the first door seal and the second door seal, the temperature difference at both sides of the first door seal and the second door seat is naturally reduced grade by grade, and the cold leakage at the door seal part of the refrigerator is obviously reduced. The door sealing structure has the advantage of simple structure, is convenient to install and use and also has the advantage that the cold leakage at the door seal part is obviously reduced.
Description
Technical field
The utility model relates to a kind of refrigerator, refrigerator-freezer technology, particularly a kind of refrigerator, freezer door seal structure.
Background technology
Be to keep temperature in the refrigerator and control ambient temperature and the Cryogenic air in the refrigerator can carry out the technical measures that heat transmits be control an important technology of reduction refrigerator, refrigerator-freezer energy resource consumption when refrigerator, refrigerator-freezer use.Existing refrigerator, refrigerator-freezer are to be provided with a circle sealing strip between the Men Tiyu casing, are commonly referred to an envelope.The door envelope is along the setting all around of the interior survey face of door body, and when the door body of refrigerator, refrigerator-freezer was closed, the door envelope will seal between the Men Tiyu casing, does not allow refrigerator, the interior cryogenic gas of refrigerator-freezer leak.In freezing or refrigerating chamber, be positioned at an envelope place, form the wide passage of 6-10mm between casing and the door body.Usually have up to 45 ° or 22 ° the temperature difference between the door envelope inboard and the outside.This makes doorframe edge that cold air in the freezing or refrigerating chamber can be by its casing and door envelope itself to exosmosis, makes the refrigerator loss of refrigeration capacity great.
Data shows according to statistics, and the position cold draining of refrigerator doors envelope accounts for 18～25% of whole refrigerator cold draining.For solving a cold draining at envelope position, the refrigerator of two-door seal structure has appearred, and it is in the inboard of first sect envelope, second sect with two hangovers that is stuck on the T shape flange that matches with it on the body with the T-slot that it was had together is set again seals.Because this envelope hangover is very long along length of door Feng Changxiang, the easy bending of its free end edge is distorted, former expect to utilize make hangover form effect and unfavorable ideal that the hollow long tube of sealing shape stops cold air against wall box at closing time.Thereby the effect that makes two-door envelope is failed to bring into play and is complied with one's wishes.
So also being arranged at present, the door sealing structure of a kind of refrigerator, refrigerator-freezer really can not realize blocking refrigerator, refrigerator-freezer problem in the place's cold draining of door envelope.Continue a kind of simple in structurely, manufacturing cost meets that mass consumption person uses prevents the cold refrigerator of a leak sealing, refrigerator-freezer.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is that the door sealing structure of present employed refrigerator, refrigerator-freezer exists the shortcoming of cold draining to design, and cost is lower, and can effectively control the door envelope of refrigerator, refrigerator-freezer cold draining problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Technical disadvantages at existing refrigerator, freezer door seal structure exist designs a kind of refrigerator, freezer door seal structure, its primary structure comprise casing, door body and be arranged on casing with the door body between the door envelope, door seals and is placed on the body.Described door body is provided with two door envelopes, and two door envelopes are airtight mutually, makes to form an air insulating layer between two door envelopes.
Described second envelope is the strip air chamber that root is connected with the door body, and the cross section of second envelope becomes " T " font.Seal up for second and offer pore, pore allows the air chamber in second envelope be in communication with the outside, and second envelope of air chamber shape can be got rid of the unnecessary air in inside when closing body, and second envelope can closely be contacted with casing.
When refrigerator door is closed, the air chamber of second envelope is compressed between the Men Tiyu casing, the passage between freezing or refrigerating chamber and first envelope has been cut off in strictness, make between first envelope and second envelope and form a seal cavity that has the temperature difference easily, so the one-level one-level has reduced the temperature difference of the both sides of first envelope, second envelope naturally, thereby the cold draining that makes refrigerator doors seal the position significantly reduces.
According to the cost and the needs of production of different refrigerators, refrigerator-freezer, the top of second envelope can be single air chamber structure, also can be stacked the forming of sub-air chamber that is approximate ellipsoidal by two cross sections, and described sub-air chamber is separate.And have at least sub-air chamber's cross section to be cellular, to increase the seal of second envelope.
The top of second envelope has at least in the sub-air chamber and is provided with the partition of cutting apart sub-air chamber.Partition is two independently little air chambers with sub-air chamber's portion.
The installation and the use of second envelope described in the utility model for convenience, connected mode between second envelope and the door body is to be provided with the fin of swinging in the both sides of the root of second envelope, the door body is provided with the groove of approximate " L " font, utilizes fin and groove to match and incompatible second sealing is fixed on the body.The root of second envelope is can be that air chamber structure also can be a solid construction.When second envelope is installed, only need root is advanced in the groove, allow fin stick in the groove and just second sealing can be fixed on the body.
The edge of door body and casing all is step-like, and allows the edge of a body and the step-like of edge of casing be complementary.
Two above-mentioned door envelopes are respectively first envelope and second envelope; First envelope is arranged on the step in the outside, and first envelope can be used refrigerator doors envelope commonly used on the present market.And second envelope is arranged on the inboard step.
The utlity model has and effectively to control refrigerator, the cold problem of freezer door leak sealing, and simple in structure, advantage such as easy to install.
