The existing frost reducing and blocking device is mostly applied to household refrigerators. Most of the principles are similar, the principle of balancing the air pressure inside and outside the refrigerator is adopted, the internal absorption amount at the door seal is reduced, wherein a one-way waterproof breathable film and a one-way ball float valve are mainly used and matched with an adsorbent, namely a molecular sieve and activated carbon, so that the effect of balancing air pressure and reducing frost is achieved.

When external air enters the box body through the vent pipe, the air needs to flow through the first waterproof breathable film and the second waterproof breathable film, and the double-layer waterproof breathable film is arranged, so that the blocking effect on water vapor in air flow is improved, the water vapor in the air is effectively prevented from entering the box body through the vent pipe, the frosting source is reduced, the frosting amount is reduced, and the comfortable convenience of product use is improved; and the second waterproof membrane also has the function of preventing water vapor in the box body from entering the vent pipe, so that the interior of the vent pipe is kept dry, and the phenomenon that the interior of the vent pipe is frozen and blocked to cause that the interior and exterior air pressure cannot be achieved is avoided. Such devices are complex and require high levels of membrane. From the technical point of view, the permeability of the membrane is poor, the pressure balancing speed is slow, in addition, the structure causes cold air leakage to a certain extent, and the reliability of the membrane is difficult to demonstrate. When used with a large volume freezer, the equilibration speed is slower, rendering the device inoperable.

Referring to fig. 1-2, the invention discloses a long-acting frost-resistant refrigerator, which comprises a refrigerator refrigeration chamber 1 and a refrigerator door body 11, wherein a refrigerator lining port 3 is arranged at the top of a refrigerator box body foaming layer 2 on the side wall of the refrigerator refrigeration chamber 1, and a long-acting frost-resistant device is arranged in the refrigerator box body foaming layer 2; the long-acting frost resisting device is communicated with the inside of the refrigerating chamber 1 of the refrigerator and the outside of the foaming layer 2 of the refrigerator box body;
the long-acting frost resisting device comprises a one-way ball float valve cavity 41 which is vertically arranged in the foaming layer 2 of the refrigerator door body and has the diameter of D1; a light floating ball 42 with the diameter of D2 is placed in the cavity 41 of the one-way ball float valve, and the weight of the light floating ball 42 is generally 0.01-10 g; the bottom of the one-way ball valve cavity 41 is provided with a one-way ball valve inlet 43 with the diameter of D3, wherein D1> D2> D3;
specifically, when the interior of the refrigerating compartment 1 of the refrigerator is refrigerated, negative pressure relative to the external atmospheric pressure is gradually generated, and the attraction force generated on the light floating ball 42 is greater than the gravity of the light floating ball 42, so that the light floating ball 42 is lifted by a certain height; at the moment, the outside is controlled to enter the refrigerating chamber 1 of the refrigerator, so that the air pressure balance is completed; in order to prevent moisture of outside air from entering the refrigerating chamber 1 of the refrigerator in the process, the long-acting frost-resisting material 6 is filled in the long-acting frost-resisting material protection cylinder 5;
the inlet 43 of the one-way ball float valve is connected with the long-acting frost-resistant material protection cylinder 5 through a communicating pipe; the long-acting frost-resisting material protection cylinder 5 is filled with a long-acting frost-resisting material 6; the long-acting frost-resistant material protection cylinder 5 is communicated with the outside of the foaming layer 2 of the refrigerator body through an air inlet pipe 7; one side of the one-way ball float valve cavity 41 is communicated with the interior of the refrigerating compartment 1 of the refrigerator through an air outlet pipe 8;

the top of the one-way ball float valve cavity 41 is attached with an anti-condensation pipe 9; the long-acting frost-resistant material protection cylinder 5 is in an arc surrounding structure near the bend 10 of the condenser; specifically, because condensed water is easily formed at the cold and hot gas exchange position, and ice blockage is easily generated in the cavity 41 of the one-way float valve, so that the one-way float valve fails, the top of the cavity 41 of the one-way float valve is close to the condensation preventing pipe 9, and the long-acting frost preventing material protection cylinder 5 is externally designed near the elbow of the condenser 10; when the refrigerator refrigerates, the anti-condensation pipe 9 and the condenser 10 generate heat, so that the interior of the device can be dried and prevented from being frozen and blocked; so that the water-blocking effect of the long-acting frost-blocking material protection cylinder 5 is effective for a long time.
