Abstract

The utility model belongs to the technical field of the refrigerator in the electrical equipment, in particular to an anti-dew structure of a refrigerator door beam. The anti-dew structure comprises a door middle beam plate (3) and a condensing anti-dew pipe (1) arranged between the door middle beam plate (3) and the interior of the refrigerator; and a heat storage device (2) capable of absorbing and storing heat energy generated by the condensing anti-dew pipe (1) and transferring the heat energy to the door middle beam plate (3) is arranged between the door middle beam plate (3) and the condensing anti-dew pipe (1). The anti-dew structure of the refrigerator door beam is capable of reducing the overhigh temperature of the middle beam plate during the power-on process of the compressor, overcoming the inflection point of the presence of dew on the middle beam plate and reducing the leakage of the heat energy of the middle beam plate to a refrigeration chamber while keeping the middle beam plate of the refrigerator door free of dew condensation.

Description

The anti-structure of revealing of a kind of refrigerator doors beam

Technical field

The utility model relates to the refrigerator technical field of household electrical appliance, is specifically related to the anti-structure of revealing of a kind of refrigerator doors beam.

Background technology

The anti-structure of revealing of refrigerator doors central sill generally is that heat or the electrical heating wire that utilizes the high pressure condenser pipe to discharge improves a central sill temperature at present, makes its dew-point temperature that is not less than respective environment humidity, avoids a central sill condensation phenomenon.Wherein utilize the high pressure condenser pipe of refrigeration system to prevent the structure of revealing; In Fig. 1; Beam slab 3 directly contact in condensation dew eliminating tube 1 and the door, and when compressor was opened, the temperature of beam slab was than higher in; In hot environment, can seriously exceed the comfort temperature of human body contact up to more than 70 degree; And in compressor shutdown,, cause that the condensation phenomenon appears in beam slab in the door because the crack between a door and its frame cold draining causes a central sill plate temperature might be lower than the dew-point temperature of prevailing circumstances again.

The utility model content

The problem that the utility model will solve provide a kind of can be in guaranteeing refrigerator doors beam slab not under the prerequisite of condensation, reduce compressor start process central sill plate temperature too high and reduce in the anti-structure of revealing of refrigerator doors beam of beam slab heat seepage of chamber between refrigeration.

For realizing above-mentioned purpose; The technical scheme of the utility model is: the anti-structure of revealing of a kind of refrigerator doors beam; Condensation dew eliminating tube between comprising beam slab in the door and being located in the door in the beam slab and refrigerator is provided with the heat that can absorb, store the generation of the condensation dew eliminating tube regenerative apparatus with beam slab in the heat transferred door of storage between beam slab and the condensation dew eliminating tube in the said door.Regenerative apparatus can be directly for being heat-storing materials such as clay, water, paraffin, crystalline hydrate salt, polyalcohol, be characterized in that amount of stored heat is big, thermal conductivity is big, temperature is suitable, good stability, nontoxic nothing corrode nonflammable explosive.

Compared with prior art, the utlity model has following beneficial effect:

The first, under the prerequisite of condensation, it is too not high to have reduced compressor start process central sill temperature, has particularly seriously exceeded the comfort temperature of human body contact under the hot environment, reduces client's complaint rate for beam slab in guaranteeing door; The second, overcome beam slab in the door occur condensation flex point---beam slab is when the process of compressor shutdown is condensation to occur the most easily in the door; The 3rd, reduced the seepage of beam slab heat chamber between refrigeration in the door.

Fig. 2 is the anti-sketch map that reveals structure of the utility model door beam.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing the utility model is carried out detailed description.

As shown in Figure 2; The utility model discloses the anti-structure of revealing of a kind of refrigerator doors beam; Condensation dew eliminating tube 1 between comprising beam slab 3 in the door and being located in the door in the beam slab 3 and refrigerator is provided with the heat that can absorb, store 1 generation of the condensation dew eliminating tube regenerative apparatus 2 with beam slab 3 in the heat transferred door of storage between beam slab 3 and the condensation dew eliminating tube 1 in the door.

In the present embodiment, regenerative apparatus 2 is for directly increasing by a heat-storing material between the beam slab 3 in condensation dew eliminating tube 1 and door, and the characteristics of this heat-storing material are that amount of stored heat is big, thermal conductivity is big, temperature is suitable, good stability, nontoxic nothing corrode nonflammable explosive.In the compressor start, condensation dew eliminating tube 1 liberated heat of high pressure transmits through heat-storing material beam slab 3 in door, and a part of heat is absorbed by beam slab in the door 3, and another part heat is absorbed and storage by heat-storing material.Absorb a part of heat the door in beam slab 3 temperature be improved, be higher than dew-point temperature, thereby prevent beam slab 3 condensations in the door.In compressor shutdown, condensation dew eliminating tube 1 is no longer emitted heat, and this moment, heat-storing material prevented beam slab condensation in the door with beam slab 3 in the heat transferred door that stores.

Concrete, heat-storing material can be clay, water, paraffin, crystalline hydrate salt, polyalcohol etc.Consider refrigerator production cost and manufacturing process; The heat-storing material of the utility model adopts composite setting paraffin (fusing point is 42 ℃), and its major advantage is that paraffin can keep the shape identical with solid and need not the proprietary material parcel when undergoing phase transition accumulation of heat.

Claims

1. a refrigerator doors beam prevents revealing structure; Comprise beam slab in the door (3) and be located at beam slab in the door (3) and refrigerator between condensation dew eliminating tube (1), it is characterized in that: be provided with the heat that can absorb, store condensation dew eliminating tube (1) generation regenerative apparatus (2) in the said door between beam slab (3) and the condensation dew eliminating tube (1) beam slab (3) in the heat transferred door of storage.
