Description

Technical Field

[0001] This application relates to the technical field of smart furniture, and in particular to a household moisture-proof and mildew-proof device. Background Technology

[0002] With the improvement of living standards and living environment, smart home devices are becoming increasingly popular. Among them, smart storage cabinets with functions such as moisture-proof, mildew-proof, and sterilization are attracting more and more attention from users. Especially in the humid climate of southern regions and islands, traditional storage methods cannot effectively isolate the storage from the humid air and some chloride ions in the surrounding environment. In addition, the temperature in the south or islands is relatively high, which makes it easy for mold and bacteria to grow, which has an adverse effect on the preservation of clothing, shoes, hats and valuables.

[0003] Currently, some smart wardrobes or storage cabinets on the market are equipped with dehumidification or sterilization devices, such as ultraviolet sterilization, activated carbon adsorption, or hot air drying. Some products also integrate spray disinfection devices, which spray disinfectant to sterilize and prevent mold in the cabinet space.

[0004] However, existing household moisture-proof and mildew-proof devices generally lack effective pretreatment of external air entering the cabinet. When users frequently open and close the cabinet door or are in high-humidity environments such as the rainy season, a large amount of undehumidified and unfiltered humid air will directly enter the cabinet, causing the humidity inside the cabinet to rise rapidly and become difficult to maintain below the safe threshold. Although such devices can treat the existing moisture and mold inside the cabinet to a certain extent, they cannot prevent the continuous intrusion of external moisture, resulting in the dehumidification system operating at high load for a long time, the dehumidification efficiency decreasing significantly over time, and low energy utilization efficiency. At the same time, since the mold spores and bacteria brought in by the humid air cannot be effectively intercepted and killed at the entrance, relying solely on local disinfection inside the cabinet is insufficient to achieve a comprehensive and continuous sterile and mildew-proof environment, leaving clothing, valuables, and other items still at risk of becoming damp and moldy, seriously affecting the actual protective effect of the product and the user experience. Summary of the Invention

[0005] To ensure a long-term moisture-proof and mildew-proof storage environment inside the cabinet, a household moisture-proof and mildew-proof device is provided.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: A household moisture-proof and mildew-proof device includes a cabinet, which has a hanging chamber and a storage chamber that are interconnected. One side of the cabinet has a sealing door that can tightly close the storage chamber and the hanging chamber. It also includes a primary air pressure regulating component and a purification component. The primary air pressure regulating component includes an airbag body installed on the outer wall of the cabinet. The bottom of the airbag body is provided with several pressure balancing working air pipes connected to the cabinet. The cabinet is provided with an air pump connected to the pressure balancing working air pipes. The purification assembly includes a first purifier installed inside the cabinet. The air inlet of the first purifier is connected to the air pump via a pipe, and the air outlet of the first purifier is connected to the cabinet, for supplying purified gas to the cabinet.

[0007] By adopting the above technical solution, clothing and other items to be stored are hooked into the hanging chamber or placed in the storage chamber, and the sealed door is closed. The airbag body is connected to the cabinet, which can cope with the different temperatures inside and outside the cabinet. When the temperature rises and the gas inside the cabinet expands, the excess gas pressure enters the airbag body through the pressure balancing working air pipe for storage, avoiding a sudden increase in gas pressure. When the temperature drops and the gas inside the cabinet contracts, the airbag body releases the pre-stored gas through the pressure balancing working air pipe to replenish the gas pressure inside the cabinet. At the same time, all the gas entering the cabinet, whether it is replenished by the air pump or replenished by the airbag, is forced to pass through the first purifier for drying treatment, removing water vapor, dust, and microorganisms that are harmful to the stored items, ensuring the cleanliness of the supplied air from the source, and creating and maintaining a dry and clean storage environment.

[0008] Preferably, it also includes a secondary air pressure regulating component, which includes a high-pressure pressure switch and a high-pressure solenoid valve controlled by it, a low-pressure pressure switch and a low-pressure solenoid valve controlled by it, and the outlet of the low-pressure solenoid valve is connected to the air inlet of the first purifier through a pipeline.

[0009] By adopting the above technical solution, when the adjustment capacity of the airbag body reaches its limit, the secondary air pressure adjustment component is activated. When the high pressure switch detects overpressure, it activates the high pressure solenoid valve to directly exhaust air to the outside of the cabinet to reduce pressure. When the low pressure switch detects negative pressure, it activates the low pressure solenoid valve to draw air from the outside. After being dried and purified by the first purifier, the air is replenished into the cabinet, realizing precise energy management and purification control of replenishing air on demand and ensuring that the replenished air is purified.

[0010] Preferably, it also includes a three-stage air pressure regulating component, which further includes a high-pressure mechanical pressure relief valve and a low-pressure mechanical pressure relief valve as redundant safety protection. The outlet of the high-pressure mechanical pressure relief valve is connected to the storage chamber. The low-pressure mechanical pressure relief valve is installed in the storage chamber, and its airflow direction is unidirectional from the outside to the cabinet. Its outlet is connected to the first purifier through a pipeline.

[0011] By adopting the above technical solution, in the event of a failure of the secondary air pressure regulating component or in extreme circumstances, the mechanical pressure relief valve, as a purely physical device, will start to work to ensure system safety. The high-pressure mechanical pressure relief valve will release pressure when there is overpressure, and the low-pressure mechanical pressure relief valve will replenish air when there is negative pressure. Moreover, the replenished air is still dried and purified by the first purifier, which constitutes a triple insurance system to avoid the risk of the cabinet environment being contaminated by unfiltered humid air due to the failure of the control system.

[0012] Preferably, the storage room is provided with at least one partition for storing items, and the partition has several through ventilation holes.

[0013] By adopting the above technical solution, the partitions are used to store items in separate areas. Users can adjust the number of partitions installed and the fixed spacing at the bottom of the cabinet according to their own needs, which can improve space utilization. The ventilation holes ensure that the purified dry air can circulate smoothly in the cabinet, penetrate the gaps between clothes and items, eliminate dead corners where moisture and mold accumulate, achieve a uniform environment in the entire cabinet space, and improve the overall effect of moisture and mold prevention.

[0014] Preferably, a support rod is fixedly provided on the inner wall of the cabinet, and a plurality of hooks for hanging items are slidably provided on the support rod.

[0015] By adopting the above technical solution, a dedicated space for hanging clothes is provided. The sliding hooks allow for flexible adjustment of the spacing according to the length and quantity of clothes, maximizing the use of vertical space and meeting the diverse storage needs of families.

[0016] Preferably, a clothes hanging bar seat is fixedly provided on the two opposite inner walls of the hanging chamber, and a clothes hanging bar is provided between the two sides of the clothes hanging bar seat.

[0017] By adopting the above technical solution, the cooperative structure of the hanging bar seat and the hanging bar provides stable and sufficient hanging support for hanging long clothes such as coats and jackets, avoiding wrinkles caused by folding and storing clothes, while making it easy for users to intuitively pick up and put away and organize clothes, thus improving the space utilization efficiency and ease of use of the hanging room.

[0018] Preferably, the purification component further includes a second purifier, the air inlet of which is provided with a fan to drive gas circulation, and the air outlet of the second purifier is connected to the cabinet body.

[0019] By adopting the above technical solution, the first purifier is mainly responsible for processing all the air in the new cabinet that is replenished by negative pressure and the gas pre-stored in the airbag. The second purifier actively circulates and purifies the air exchanged between the inside and outside of the cabinet after the door is opened and closed. The fan provides the power for forced circulation and can actively draw air from all corners of the cabinet and pass it through the second purifier to ensure that the air in the entire space is fully, quickly and evenly processed, which significantly improves the purification efficiency and speed.

[0020] Preferably, the cabinet is also equipped with a humidity sensor, which is electrically connected to the fan and is used to automatically start and stop the fan according to the humidity inside the cabinet.

[0021] By adopting the above technical solution, the system achieves intelligent and energy-saving operation. The humidity sensor monitors the environment inside the cabinet in real time, and only when the humidity exceeds the set threshold will the fan automatically start to begin forced internal air circulation to adsorb moisture. Once the humidity drops to a safe range, it will stop working, avoiding continuous ineffective operation of the equipment, greatly reducing energy consumption and extending the equipment life.

[0022] Preferably, the inner wall of the cabinet is provided with an open hanging bag rack for hanging absorbent.

[0023] By adopting the above technical solution, the gas inside the cabinet that has not passed through the second purifier can be adsorbed and dried by the adsorbent on the open adsorbent hanging bag rack, ensuring that the gas inside the cabinet is in a purified state.

[0024] Preferably, the structure of the cabinet is suitable for storage cabinets or storage boxes.

[0025] By adopting the above technical solutions, regardless of differences in size or number of doors, the structure of the primary air pressure regulating component and the purification component can be applied to storage devices of different shapes to achieve moisture-proof and mildew-proof functions.

[0026] In summary, this application has at least the following beneficial effects: 1. Traditional solutions passively deal with moisture and mold that have entered the cabinet, while this application constructs and maintains a dry storage environment inside the cabinet by using an airbag body and an air pump, forming a dynamic air pressure barrier. This barrier can effectively resist the intrusion of high humidity and bacteria-containing air from the outside due to opening and closing the door or changes in ambient temperature, thus shifting the focus of moisture and mold prevention from "internal treatment" to "entry blocking". 2. Through the comprehensive design of the pressure regulating components, including a primary airbag, a secondary solenoid valve, and a tertiary mechanical valve, the system can intelligently ensure that the air pressure inside the cabinet is consistent with the air pressure outside the cabinet, without the destructive effects of positive or negative pressure. This enables a completely sealed and absolutely enclosed independent cabinet space, providing extremely high stability for the storage environment inside the cabinet. 3. All air entering the cabinet through the air pump, solenoid valve, and mechanical valve emergency air supply is forcibly guided through the first purifier for drying and purification, ensuring the safety and reliability of the air source. At the same time, combined with intelligent control by a humidity sensor, the fan is automatically activated only when the humidity exceeds the set threshold. The fan actively circulates and purifies the existing air in the cabinet, which can reduce the initial humidity in the cabinet more quickly and maintain an ultra-low humidity environment.

[0029] The following section provides a more detailed description, in conjunction with the accompanying diagrams: As attached Figure 1As shown, a household moisture-proof and mildew-proof device includes a cabinet 1, which is widely used in smart home devices. It is a smart storage cabinet with functions such as moisture-proof, mildew-proof, and sterilization. The structure of the cabinet 1 is suitable for storage cabinets or storage boxes. Regardless of size or number of doors, it can be used in different forms. Especially in the humid southern region, it can greatly reduce the accumulation of moisture and the growth of mold and bacteria inside the cabinet 1. The cabinet 1 includes a storage chamber 11, a hanging chamber 12 and a storage chamber 11 arranged sequentially from top to bottom. The storage chamber 11 and the hanging chamber 12 are interconnected. The cabinet 1 is assembled from several sheet metal parts, and all the joints of the sheet metal parts of the cabinet 1 are fully welded. The structure of the cabinet 1 is suitable for storage cabinets or storage boxes, ensuring that storage devices of different forms can realize storage functions.

[0030] As attached Figure 2 and attached Figure 3 As shown, two hanging rod seats 13 are fixedly installed on the two opposite inner walls of the hanging chamber 12. There are two hanging rod seats 13, and a horizontally arranged hanging rod 14 is fixedly connected between the two hanging rod seats 13. The hanging rod 14 is used to hook some large clothes. There is a partition 15 in the top storage chamber 11. The top storage chamber 11 can be used to store some infrequently used or more valuable items. There are three partitions 15 in the bottom storage chamber 11. The partitions 15 are fixedly connected to the inner wall of the cabinet 1. The bottom storage chamber 11 can be used to store some frequently used items. The number of partitions 15 installed in the bottom storage chamber 11 and the fixed spacing can be adjusted by the user according to their own needs.

[0031] One side of the cabinet 1 is provided with a sealing door 16 that can tightly close the storage chamber 11 and the hanging chamber 12. There are two sealing doors 16. One sealing door 16 can be sealed and closed separately when the top is stored, and the other sealing door 16 can seal and close the hanging chamber 12 and the bottom storage chamber 11 separately. When the sealing door 16 is closed, the interior of the cabinet 1 becomes a highly sealed independent space, and the internal gas cannot be freely exchanged with the external gas.

[0032] The partition 15 has multiple through-holes 151 along the vertical direction. The through-holes 151 ensure that the air in the top storage chamber 11, the hanging chamber 12 and the bottom storage chamber 11 can circulate smoothly in the cabinet, penetrate the gaps between clothes and items, and achieve a uniform environment in the entire cabinet space.

[0033] The inner wall of the cabinet 1 is also horizontally fixed with a support rod 17, and multiple hooks 171 for hanging items are slidably provided on the support rod 17, providing a dedicated space for hanging smaller clothes. The sliding hooks 171 can be flexibly adjusted according to the length and quantity of clothes to maximize the use of vertical space and meet the diverse storage needs of the family.

[0034] As attached Figure 4 and attached Figure 5 As shown, a household moisture-proof and mildew-proof device further includes a primary air pressure regulating component 2, a secondary air pressure regulating component 3, a tertiary air pressure regulating component 4, and a purification component 5. The primary air pressure regulating component 2 includes an airbag enclosure 21 and an airbag body 22. The airbag enclosure 21 is plate-shaped and is fixedly installed on the top of the cabinet 1 by welding screws. There are four airbag enclosures 21 here, which are mutually enclosed and fixed to form a placement space. The airbag body 22 is made of elastic material and is installed in the placement space. The volume of the airbag body 22 is slightly smaller than the placement space. The airbag enclosure 21 can limit the outer periphery of the airbag body 22. The airbag body 22 is usually made of rubber material with good elasticity and sealing properties, and can expand or contract or spring up according to the change of internal gas volume.

[0035] The bottom of the airbag body 22 is fixedly connected to a pressure balancing working air pipe 221. There are two pressure balancing working air pipes 221 here. The airbag body 22 is connected to the inside of the cabinet 1 through the pressure balancing working air pipes 221. An air pump 23 is fixed on the inner wall of the top of the cabinet 1. One end of the air pump 23 is connected to one of the pressure balancing working air pipes 221, and the other end of the air pump 23 is connected to the top storage chamber 11. The function of the air pump 23 is to assist the circulation of gas between the cabinet 1 and the airbag body 22. When the temperature rises and the gas in the cabinet expands, the excess gas pressure enters the airbag body 22 for storage through the pressure balancing working air pipe 221 to prevent the gas pressure from rising suddenly. When the temperature drops and the gas in the cabinet contracts, the airbag body 22 releases the pre-stored gas through the pressure balancing working air pipe 221 to replenish the gas pressure in the cabinet, forming a first-level gas pressure regulation in the cabinet 1.

[0036] An airbag pull cord 24 is provided between the top of the airbag enclosure 21 and the top of the airbag body 22 to connect the two. The airbag pull cord 24 is made of elastic material. By precisely controlling the length of the airbag pull cord 24, it is ensured that the airbag body 22 is always in the middle position between the minimum contraction and the maximum expansion after the door is closed. The restraining effect of the airbag pull cord 24 can prevent the airbag body 22 from being over-compressed, ensuring that it always has effective gas regulation capability, and preventing the airbag body 22 from collapsing due to excessive looseness or being overly tight to restrict the expansion space.

[0037] As attached Figure 5 and attached Figure 6As shown, an instrument box 6 is also fixed on the top of the cabinet 1. The secondary air pressure regulating component 3 also includes a high-pressure switch 31, a low-pressure switch 32, a high-pressure solenoid valve 33, and a low-pressure solenoid valve 34 located in the instrument box 6. The high-pressure switch 31 and the low-pressure switch 32 are electrical control components. The high-pressure switch 31 is electrically connected to the high-pressure solenoid valve 33, and the low-pressure switch 32 is electrically connected to the low-pressure solenoid valve 34. When the high-pressure switch 31 or the low-pressure switch 32 detects that the air pressure inside the cabinet 1 has reached the set value, it will trigger the corresponding solenoid valve to act.

[0038] Both the high-pressure solenoid valve 33 and the low-pressure solenoid valve 34 are connected to the inside of the cabinet 1. The high-pressure solenoid valve 33 and the low-pressure solenoid valve 34 are generally electromagnetically controlled valves. When the airbag body 22 has insufficient adjustment capacity, the high-pressure switch 31 or the low-pressure switch 32 will activate the corresponding electrically connected high-pressure solenoid valve 33 or low-pressure solenoid valve 34 respectively. The high-pressure solenoid valve 33 exhausts air directly to the outside and quickly reduces the pressure, while the low-pressure solenoid valve 34 draws air from the outside to avoid the harm of negative pressure, thus forming a two-stage air pressure regulation inside the cabinet 1.

[0039] The three-stage air pressure regulating assembly 4 includes a high-pressure mechanical pressure relief valve 41 and a low-pressure mechanical pressure relief valve 42. The high-pressure mechanical pressure relief valve 41 is located inside the instrument box 6 and is connected to the top storage chamber 11. The high-pressure mechanical pressure relief valve 41 discharges air in time when the air pressure inside the cabinet 1 is too high. The low-pressure mechanical pressure relief valve 42 is installed upside down on the inner wall of the top of the cabinet 1 and is connected to the instrument box 6. When the air pressure in the top storage chamber 11 is too low, it draws air from the outside into the top storage chamber 11. The high-pressure mechanical pressure relief valve 41 and the low-pressure mechanical pressure relief valve 42 serve as the three-stage air pressure regulator for the cabinet 1.

[0040] As attached Figure 7 and attached Figure 8 As shown, the purification component 5 includes a first purifier 51 and a second purifier 52 installed inside the cabinet 1. Both the first purifier 51 and the second purifier 52 are box-shaped structures. The first purifier 51 is fixedly installed on the top inner wall of the cabinet 1, and the second purifier 52 is fixedly installed on the bottom inner wall of the cabinet 1. Both the first purifier 51 and the second purifier 52 have impurity adsorption chambers 53, and the impurity adsorption chambers 53 are equipped with hanging bag racks 54 for hanging adsorbents. The adsorbents can be activated carbon, molecular sieves, etc., which have strong adsorption capacity and can effectively adsorb moisture, mold and other factors in the air that can cause deliquescence and mildew on clothing.

[0041] The inner wall of the cabinet 1 is equipped with an open-type hanging bag rack 54 for hanging adsorbents, such as activated carbon bags, which can be directly hung on the adsorbents. This allows the gas in the cabinet 1 that has not passed through the second purifier 52 to be adsorbed and dried by the adsorbents on the open-type adsorbent hanging bag rack 54, ensuring that the gas in the cabinet 1 is in a purified state.

[0042] Both the first purifier 51 and the second purifier 52 are equipped with absorbent cotton 55 for filtering gas at one end of the air inlet. The gas in the storage chamber 11 will first pass through the absorbent cotton 55 and then flow into the impurity adsorption chamber 53. As a pre-filter, the absorbent cotton 55 can effectively filter out dust, particulate matter and other impurities in the air, preventing these impurities from carrying harmful microorganisms into the cabinet 1. The air containing impurities entering the cabinet 1 from the cabinet door is purified by the absorbent cotton 55 at the front end of the second purifier 52, ensuring the stability of the purification efficiency.

[0043] As attached Figure 6 As shown, the air inlet of the first purifier 51 is connected to the air outlet of the air pump 23, the air outlet of the low-pressure solenoid valve 34, and the air outlet of the low-pressure mechanical pressure relief valve 42 through pipes. The air outlet of the first purifier 51 is connected to the top storage chamber 11. The gas released by the air pump 23, the low-pressure solenoid valve 34, and the low-pressure mechanical pressure relief valve 42 must be dried and purified by the adsorbent in the first purifier 51 before it can be discharged into the top storage chamber 11. The adsorbent can adsorb and remove moisture and other elements carried in the air, and deliver the purified gas to the top storage chamber 11 to improve the environment inside the cabinet.

[0044] As attached Figure 3 and attached Figure 7 As shown, the air outlet of the second purifier 52 is connected to the bottom storage chamber 11. The air inlet of the second purifier 52 is equipped with a fan 56 that drives gas circulation. A humidity sensor 7 is fixedly connected to the inner wall of the cabinet 1. The humidity sensor 7 is electrically connected to the fan 56 and is used to automatically start and stop the fan 56 according to the humidity inside the cabinet. When the humidity inside the cabinet exceeds the set value, the humidity sensor 7 will trigger the fan 56 to turn on, so that the gas inside the cabinet 1 flows through the second purifier 52 at the bottom under the active drive of the fan 56 for purification, reducing the humidity inside the cabinet. When the humidity inside the cabinet reaches the safe threshold, the fan 56 will automatically stop, realizing intelligent humidity regulation.

[0045] A limit switch 8 is fixedly connected to the inner wall of the cabinet 1 for triggering when the cabinet door abuts. A time relay 9 is installed on the instrument box 6. The limit switch 8 and the time relay 9 are electrically connected to the air pump 23. When the cabinet door is closed, the limit switch 8 is triggered, which in turn triggers the fan 56 at the bottom of the cabinet 1 and the air pump 23 at the top. The gas released by the air pump 23 flows through the first purifier 51 at the top of the cabinet 1 and then flows into the top storage chamber 11 after purification. The fan 56 drives the gas in the cabinet 1 to flow through the second purifier 52 at the bottom of the cabinet 1 and then flows into the bottom storage chamber 11 after purification. The time relay 9 controls the start and stop of the top purification air pump 23 and the bottom purification fan 56 by setting a time.

[0046] The implementation principle of this embodiment is as follows: After placing clothing, shoes, and other items to be stored into cabinet 1, close the sealing door 16. The air pump 23 and the airbag body 22 work together to automatically adjust according to the temperature difference between the inside and outside of cabinet 1. When the temperature rises and causes the gas inside the cabinet to expand, the excess gas is temporarily stored in the airbag body 22 through the pressure balancing working air pipe 221 to prevent excessive positive pressure. When the temperature drops and the gas inside cabinet 1 contracts, the pre-stored gas in the airbag body 22 is replenished back into cabinet 1 through the same pipe to prevent negative pressure from forming. When the adjustment capacity of the airbag body 22 is insufficient, the high and low pressure switches 32 control the opening and closing of the corresponding solenoid valves to form a two-stage air pressure regulation. The third stage is provided by a mechanical pressure relief valve for more comprehensive protection. In the event of a failure in the electrical control system, the valve will mechanically activate to prevent damage from overpressure or negative pressure. At the same time, whether it is the gas supplied by the air pump 23, the air drawn in from the outside by the low-pressure solenoid valve 34, or the air drawn in by the low-pressure mechanical pressure relief valve 42 as a safety redundancy, all air sources are forced to pass through the first purifier 51 without exception. The adsorbent in the first purifier 51 performs deep drying and purification of the airflow, effectively removing moisture, mold and dust particles, ensuring the absolute dryness and cleanliness of the supplied air from the source. Humidity sensor 7 monitors the humidity inside the cabinet in real time. Once the humidity exceeds the set threshold, the fan 56 is immediately activated to drive the air inside the cabinet 1 to form a circulating airflow. This forces the air to pass through the adsorbent layer inside the second purifier 52 for continuous dehumidification and purification, eliminating dead spots where local moisture accumulates. This ensures that the humidity inside the entire cabinet is uniform and stable below the safe threshold, ensuring the reliability and safety of long-term storage of clothing, shoes, and other items.

[0047] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
