After a period of use, the refrigeration and freezing device can form frosting on the inner wall of the refrigeration and freezing device (particularly a refrigerator, and the frosting amount generated by the refrigeration and freezing device is more obvious). One important reason for the occurrence of frost is that when the compressor is turned on and off, the pressure inside the refrigerating and freezing device changes, and the humid air of the external environment enters the inside of the refrigerating and freezing device through the door seam, and then the moisture in the humid air condenses to form frost. The large amount of frosting not only causes an increase in the amount of electricity used by the refrigerating and freezing apparatus, but also causes a very poor feeling of experience when the user uses the refrigerating and freezing apparatus.

The related art provides an air flow dehumidification module for a refrigerating and freezing device, wherein the air flow dehumidification module comprises an air inlet pipe section, a cold transfer dehumidification pipe section and an air outlet pipe section which are sequentially communicated, the air inlet pipe section is communicated with the external environment, and the air outlet pipe section is communicated with a storage compartment so as to allow air flow in the external environment to flow into the storage compartment through the air flow dehumidification module; the cooling and dehumidifying pipe section is provided with a fin component for condensing and dehumidifying air flow flowing from the external environment to the storage compartment; and the air flow dehumidification module further comprises a heating device which is at least arranged on the outer wall of the tube body of the cooling dehumidification tube section and used for promoting frosting generated by the fin component to melt, and the density degree of the heating device in each area of the outer wall of the tube body is positively related to the frosting quantity of the fin component in the corresponding area of the cooling dehumidification tube section.

In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

Referring to fig. 1 to 5, in which arrows in fig. 4 indicate air flow directions, an embodiment of the present disclosure provides an air flow dehumidifying module for a refrigerating and freezing device having a storage compartment for storing articles, the air flow dehumidifying module comprising: the air inlet pipe section 10, the cooling and dehumidifying pipe section 20, the air outlet pipe section 30 and the floating ball 40, wherein the air inlet pipe section 10 is communicated with the external environment; the cold transfer dehumidification section 20 is provided with a fin assembly 24 for condensing and dehumidifying the air flow flowing from the external environment to the storage compartment; the air outlet pipe section 30 is communicated with the storage compartment so as to allow air flow in the external environment to flow to the storage compartment through the air flow dehumidification module; the floating ball 40 is arranged on one of the air inlet pipe section 10, the cold transfer dehumidification pipe section 20 and the air outlet pipe section 30 and is used for controlling the on-off of a pipeline of the air flow dehumidification module; wherein the air inlet pipe section 10, the cool-transferring dehumidifying pipe section 20 and the air outlet pipe section 30 are sequentially communicated.

By adopting the air flow dehumidification module for the refrigerating and freezing device provided by the embodiment of the disclosure, through arranging the air inlet pipe section 10, the cold transfer dehumidification pipe section 20 and the air outlet pipe section 30 which are sequentially communicated and communicating the air inlet pipe section 10 with the external environment, the air outlet pipe section 30 is communicated with the storage compartment of the refrigerating and freezing device, and external air can flow into the storage compartment of the refrigerating and freezing device along the air inlet pipe section 10, the cold transfer dehumidification pipe section 20 and the air outlet pipe section 30; by providing the cold transfer dehumidification section 20 with a fin assembly 24 for condensing and dehumidifying the air flow from the external environment to the storage compartment, the fin assembly 24 allows moisture in the air flow flowing through the cold transfer dehumidification section 20 to condense on the fin assembly 24, thereby functioning as condensation dehumidification. The fin assemblies 24 can increase the contact area with the air flow, so that the moisture in the air flow is condensed more fully and thoroughly, the air flow flowing to the storage compartment is dry air flow with low humidity, and the frosting amount in the storage compartment is reduced; through setting up floater 40, floater 40 can control the break-make of gas outlet line, can control whether external air current can get into along the interior in the air current dehumidification module inflow storing room, through when not needing to get into in the storing room of freezing refrigerating plant, close the passageway of air current dehumidification module, can avoid the hot air to flow into the problem that leads to the energy consumption to increase in the storing room of freezing refrigerating plant to appear.

Specifically, when the compressor is started, a pressure difference is generated between the inside and the outside of the storage compartment of the freezing and refrigerating device, and under the action of the pressure difference, the floating ball 40 floats upwards to open the pipeline of the air flow dehumidification module, so that the external air flow is sucked into the storage compartment due to the respiratory effect. In the process, the external air firstly passes through the air inlet pipe section 10 and then passes through the cold transmission dehumidification pipe section 20, then flows into the storage room of the freezing and refrigerating device along the air outlet pipe section 30, when the external air passes through the cold transmission dehumidification pipe section 20, the fin assemblies 24 in the cold transmission dehumidification pipe section 20 can condense water vapor in the air, and then the dried air enters the storage room again; when the compressor is shut down or the pressure difference between the inside and the outside of the storage compartment of the freezing and refrigerating device is reduced to zero or the pressure difference is very small, the floating ball 40 sinks to close the pipeline of the air flow dehumidification module, and the channel for air exchange of the storage compartment of the freezing and refrigerating device is closed, so that the energy consumption of the freezing and refrigerating device cannot be increased.

Optionally, the floating ball 40 may be disposed on any one of the air inlet pipe section 10, the cool-transferring dehumidifying pipe section 20 and the air outlet pipe section 30, and by providing a receiving cavity in the pipe section, the floating ball 40 can float up and down under the pressure difference in the receiving cavity, so as to open or close the passage of the air flow dehumidifying module.

Optionally, the joints between the air inlet pipe section 10 and the cold transfer dehumidification pipe section 20, between the cold transfer dehumidification pipe section 20 and the air outlet pipe section 30, and between the air outlet pipe section 30 and the storage compartment are all completely sealed by adopting a sealing structure, so that air flow in the air flow dehumidification module is prevented from leaking outwards.

Alternatively, the sealing structure may be, for example, a sealant, a sealing ring, and/or an adhesive tape, etc.

In some embodiments, the cool-transferring dehumidified pipe section includes: the housing 21, the housing 21 defines a containing cavity 211, two ends of the housing 21 are respectively provided with a first connecting pipe section 22 and a second connecting pipe section 23, the first connecting pipe section 22 is communicated with the air inlet pipe section 10, and the second connecting pipe section 23 is communicated with the air outlet pipe section 30; the fin assembly 24 is disposed in the accommodating cavity 211, and an end portion of the second connecting tube segment 23 facing the air outlet tube segment 30 has a boss 231, and the floating ball 40 is disposed on the boss 231 for sealing a port of the second connecting tube segment 23 facing the air outlet tube segment 30.

By adopting the air flow dehumidification module for the refrigerating and freezing device provided by the embodiment of the disclosure, the first connecting pipe section 22 and the second connecting pipe section 23 are respectively arranged at the two ends of the shell 21, so that the shell 21 is conveniently connected with the air inlet pipe section 10 and the air outlet pipe section 30 respectively. By providing the boss 231 at the end of the second connection pipe section 23 and the air outlet pipe section 30 and providing the floating ball 40 on the boss 231, the floating ball 40 can seal the port of the second connection pipe section 23 to seal the second connection pipe section 23 and the air outlet pipe section 30, so as to prevent air flow from flowing from the second connection pipe section 23 into the air outlet pipe section 30.

Optionally, a fin assembly 24 is disposed in the accommodating cavity 211, and the fin assembly 24 includes a plurality of condensing fins disposed at intervals and a plurality of fin passages formed by the plurality of condensing fins being partitioned. It will be appreciated that a fin channel is formed between each adjacent two of the condensing fins, and between the end condensing fins and the inner wall of the air dehumidifying module.

To facilitate the placement of the fin assembly 24, the housing 21 of the cool-transfer dehumidification tube segment 20 may include a body and a cover that are sealingly connected together. Specifically, the body and the cover body can be sealingly connected together by a low temperature resistant and waterproof sealant; the main body and the cover body can be connected together in a sealing way through a combination mode of the screw element and the sealing ring. The body and cover together define a receiving cavity 211 in communication with the inlet tube segment 10 and the outlet tube segment 30, and the fin assembly 24 is disposed in the receiving cavity 211 and is integrally formed with the body.

Optionally, each condensing fin extends straight in the direction of airflow in the cold transfer desiccant tube segment 20. The plurality of condensing fins are arranged at intervals in a direction perpendicular to the flow direction of the air flow and are parallel to each other. That is, each condensing fin is a fin body extending straight without corners or bends. Thus, it is convenient for processing and forming

Alternatively, the width of the plurality of fin passages arranged from the middle of the fin assembly 24 to both sides thereof is gradually increased, and the distance between the air inlets and the air flow inlets of the plurality of fin passages arranged from the middle of the fin assembly 24 to both sides thereof is gradually increased so that the air flow amount of each fin passage is the same. For example, when the air dehumidifying module extends vertically, the width of the plurality of fin passages arranged from the middle of the fin assembly 24 to the lateral sides thereof gradually increases, and the distance between the air inlets of the plurality of fin passages arranged from the middle of the fin assembly 24 to the lateral sides thereof and the air inlets of the fin assembly 24 gradually increases. That is, the width of the fin channels facing the air flow inlet of the fin assembly 24 is the smallest, closest to the air flow inlet of the fin assembly 24. The greater the width of the fin channels that are offset from the air flow inlet of the fin assembly 24, the further from the air flow inlet of the fin assembly 24. Therefore, the air flow of each fin channel is consistent, and each branch air flow flowing through each fin channel can be condensed and dehumidified more fully and thoroughly, so that frosting of each condensing fin is relatively uniform, and more uniform and thorough defrosting of each condensing fin is facilitated.

The waterproof breathable film is also called unidirectional breathing paper, the surface of the waterproof breathable film is provided with an extremely fine micropore structure, the minimum diameter of water drops is about 0.02 mm, the diameter of water vapor molecules is only 0.0000004 mm, the diameters of the waterproof breathable film and the water vapor molecules are greatly different, according to the concentration gradient difference diffusion principle, water vapor can freely pass through micropores, and liquid water and water drops cannot pass through breathing paper materials due to the surface tension effect of the liquid water and the water drops, so that the waterproof breathable film has excellent waterproof performance and breathability.

In some embodiments, the cool-transferring dehumidified pipe section further comprises: the waterproof and breathable film 50 covers the communication place between the accommodating cavity 211 and the second connecting pipe section 23, so that moisture is prevented from flowing from the accommodating cavity 211 to the air outlet pipe section 30 and into the storage chamber.

By means of the air dehumidifying module for the refrigerating and freezing device, the waterproof breathable film 50 is arranged, and due to the fact that the waterproof breathable film 50 has good waterproof performance and breathability, when the moisture absorption capacity of the cooling dehumidifying pipe section 20 of the air dehumidifying module is reduced, the waterproof breathable film 50 is arranged at the communicating position of the containing cavity 211 and the second connecting pipe section 23, moisture in air passing through the waterproof breathable film 50 cannot penetrate through the film layer, water in the air can be further filtered, the air can normally penetrate through the film layer to flow into the air outlet pipe section 30, and therefore the water and frost control capacity of the air dehumidifying module can be improved, and the possibility of frosting in a storage room due to inflow of external air is further reduced.

In some embodiments, the waterproof breathable membrane 50 is made of polyethylene or polypropylene material.

In some embodiments, the cold transfer dehumidification section further includes at least one phase change energy storage unit disposed outside of the housing 21 to allow the cold stored by the phase change energy storage unit to be transferred through the housing 21 to the fin assembly 24 in the cold transfer dehumidification section 20.

It will be appreciated that each phase change energy storage unit comprises a phase change energy storage material which absorbs and stores cold energy from the refrigeration and freezing device during one phase change process and releases the stored cold energy during the other phase change process, and the released cold energy is utilized to promote the condensation of moisture in the air flow flowing through the cold transfer and dehumidification pipe section 20 on the fin assembly 24, thereby achieving the purpose of dehumidifying the air flow. Because the two phase change processes of the phase change energy storage material are continuously carried out, the air flow can be effectively condensed and dehumidified for a long time without periodic replacement, and thus, frosting can be effectively and permanently prevented.

In some embodiments, the air flow dehumidification module for a refrigeration chiller further comprises: and a bracket 25, wherein the bracket 25 is arranged at one side of the shell 21 so as to connect the shell 21 with the refrigerating and freezing device.
