Description

A dehumidification module and cabinet Technical Field

[0001] This utility model relates to the field of storage equipment, and in particular to a dehumidification module and cabinet. Background Technology

[0002] Air in the natural environment contains a certain amount of moisture. Air humidity refers to the degree of water content in the air, which can be expressed as relative humidity (RH). %RH is the quantitative unit of relative humidity. The higher the value, the more humid the air environment under a certain temperature condition. During the rainy season, the humidity in many areas often reaches above 70%RH. Generally, exceeding 60%RH is a condition for mold growth. Therefore, every household and business should pay attention to dehumidification and moisture prevention. On the other hand, in winter, the air is very dry, especially in the north, where the dryness can even be below 10%RH. Such a high dryness environment is prone to static electricity and is not conducive to the preservation of printed materials, films, cultural relics, seeds, living tissues, etc.

[0003] In daily life and work, there are many items that are susceptible to moisture, such as cameras, lenses, precision instruments, electronic appliances, and traditional Chinese medicine. If these items are placed in a humid environment for a long time, they will grow mold, rust, age, deteriorate, malfunction, deform, change taste, fade, and rot. In particular, if traditional Chinese medicine and food become damp and moldy, it can lead to health problems for people.

[0004] Therefore, in summary, moisture-controlled storage cabinets (which control the humidity inside the cabinet within the appropriate range required by the stored items) are very effective. Maintaining the humidity inside the cabinet within a relatively narrow range effectively protects the stored items. Regarding drying and moisture prevention: Early moisture-proof storage cabinets used airtight boxes containing a certain amount of desiccant packets, with humidity levels visible on the outer surface. Their advantages were low price and ease of use. However, since the desiccant packets were disposable, they lost their dehumidifying ability once they reached a certain saturation point. Furthermore, the failure to absorb and remove moisture in a timely manner could actually have a moisturizing effect. If the desiccant packets were not replaced regularly, the cabinet would become a humidifier, a major drawback.

[0005] With advancements in science and technology, desiccant materials that can be repeatedly used by heating have emerged, such as silica gel desiccants and molecular sieves. Heating removes moisture from these materials, allowing for repeated reuse and overcoming the drawback of frequent desiccant pack replacement. Furthermore, the integration of microcomputer and temperature control systems enables advanced moisture-proof storage cabinets to automatically regulate temperature and humidity. Constant temperature and humidity storage cabinets have revolutionized the field of goods storage and possess significant application and market value.

[0006] However, existing temperature and humidity storage cabinets often use a single dehumidification chamber in their dehumidification system design, resulting in low dehumidification efficiency and high energy consumption. In particular, they are difficult to meet the requirements of extremely dryness and ultra-low humidity. Furthermore, the dehumidification process must be stopped when the dried material is regenerated, and the function of continuous dehumidification cannot be achieved. Summary of the Invention

The third main pipeline is connected to the first processing pipeline. The fifth branch pipeline and the sixth branch pipeline are both connected to the third main pipeline.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] This utility model provides a dehumidification module.

[0033] As shown in Figure 1, the dehumidification module provided in this embodiment of the present invention includes a housing and a dehumidification air pump 10, a regeneration air pump 20, a first flow direction control unit 30, a second flow direction control unit 40, a first processing pipe 50, and a second processing pipe 60 disposed within the housing. The two ends of the first processing pipe 50 and the second processing pipe 60 are respectively connected to the first flow direction control unit 30 and the second flow direction control unit 40. The dehumidification air pump 10 has a first air inlet 80 disposed within the cabinet 70, and the regeneration air pump 20 has a second air inlet 90 disposed outside the cabinet 70. The second flow direction control unit 40 includes a first air outlet 100 disposed within the cabinet 70 and a second air outlet 110 disposed outside the cabinet 70. The dehumidification air pump 10 and the regeneration air pump 20 are both connected to the first flow direction control unit 30, the first processing pipe 50, and the second processing pipe 60, so that the dehumidification module can switch between the following two operating states:

[0034] In the first working state, the first processing pipe 50 is connected to the dehumidifying air pump 10, and the second processing pipe 60 is connected to the regeneration air pump 20.

[0035] In the second working state, the first processing pipe 50 is connected to the regeneration gas pump 20, and the second processing pipe 60 is connected to the dehumidification gas pump 10.

[0036] In this embodiment, the dehumidifying air pump 10 draws air from the cabinet 70 and dehumidifies it through the first processing pipe 50 or the second processing pipe 60. The dehumidifying pipe contains a molecular sieve that adsorbs and filters out water molecules in the air to obtain dry air, which is then sent into the sealed cabinet 70.

[0037] The regeneration air pump 20 draws air from outside the cabinet and passes it through the first dehumidification treatment pipe 50 or the second treatment pipe 60. At this time, there is a heating wire inside the pipe. During regeneration, the temperature inside the first treatment pipe 50 or the second treatment pipe 60 heats the molecular sieve inside the pipe. The water molecules originally adsorbed inside the molecular sieve are vaporized by the high temperature and driven by the air from the air pump.

[0038] When the first processing tube 50 performs dehumidification, the second processing tube 60 can perform regeneration. When the first processing tube 50 performs regeneration, it can also perform dehumidification. This continuously dehumidifies the sealed air inside the cabinet, ensuring stable humidity inside the cabinet. This not only ensures the cleanliness of the air inside the cabinet but also accelerates the drying speed, making regeneration efficient, energy-saving, low-carbon, and environmentally friendly.

[0040] The second flow control unit 40 includes a third solenoid valve control group 41 and a fourth solenoid valve control group 42.

Both the third solenoid valve control group 41 and the fourth solenoid valve control group 42 are connected to the first air outlet 100 and the second air outlet 110.
