Description

Technical Field

[0001] This invention relates to the field of dehumidification, and in particular to dehumidifiers and dehumidification methods. Background Technology

[0002] In refrigeration and dehumidification equipment, evaporators and condensers are usually arranged in a close and compact manner.

[0003] Since the evaporator generates low-temperature cooling energy when it is working, and the condenser releases high-temperature heat when it is working, their adjacent arrangement can easily lead to mutual transfer and interference of cooling and heat.

[0004] This phenomenon directly leads to a decrease in the overall heat exchange efficiency of the refrigeration system, a reduction in cooling capacity, an increase in operating energy consumption, and a decrease in temperature control accuracy.

[0005] Meanwhile, heat interference can easily lead to higher condensing pressure, and loss of cooling capacity can easily cause evaporator frosting and icing, thereby increasing the operating load of the compressor. Long-term operation will seriously affect the working stability and service life of the refrigeration system. Summary of the Invention

[0006] Therefore, it is necessary to provide a dehumidifier and dehumidification method to address the problem that adjacent arrangement of evaporators and condensers can easily lead to mutual transfer and interference of cold and heat.

[0007] A dehumidifier, the dehumidifier comprising: The housing assembly has a mounting cavity, an air inlet and an air outlet, and a water storage tank at the bottom of the mounting cavity; A fan assembly is disposed on the housing assembly and located within the mounting cavity, the fan assembly being used to deliver air entering through the air inlet to the air outlet; A refrigeration assembly includes a compressor, an evaporator, a condenser assembly, and a heat insulation assembly. The compressor, evaporator, and condenser assembly are mounted on the housing assembly and located within the mounting cavity. The evaporator is adjacent to the air inlet and connected to the compressor. The compressor is connected to the condenser assembly. The condenser assembly is connected to the evaporator via a throttling element and is adjacent to the evaporator. The heat insulation assembly is located between the evaporator and the condenser assembly to block heat transfer between them. A water storage tank is located below the evaporator to collect condensate generated during its operation. The condenser assembly has a condensate channel, with its inlet and outlet connected to the water storage tank. The liquid in the water storage tank can circulate within the condensate channel. A water outlet component, which is disposed on the housing assembly and located at the top of the housing assembly; A first pump body assembly, one end of which is connected to the water storage tank and the other end of which is connected to the water outlet; A top water tank is detachably mounted on the housing assembly, and when mounted on the housing assembly, the top water tank can communicate with the water outlet.

[0008] The dehumidifier disclosed in this application achieves an orderly layout of components through the integrated design of the mounting cavity: the shell assembly has an independent mounting cavity, which integrates core components such as the fan assembly, refrigeration assembly, and first pump assembly into the mounting cavity, thereby achieving an orderly arrangement of the components, avoiding mutual interference between components, and significantly reducing the overall size of the dehumidifier.

[0009] The heat insulation component installed between the adjacent condenser and evaporator can effectively block heat transfer between the evaporator and condenser, preventing the cooling capacity generated by the evaporator from being offset by the heat dissipated by the condenser. At the same time, it prevents the heat from the condenser from penetrating to the surface of the evaporator, ensuring that the evaporator always maintains a low temperature and the condenser always maintains a high-efficiency heat release state. This improves the heat exchange efficiency of the refrigerant, makes the refrigeration cycle smoother, and ultimately achieves a significant improvement in dehumidification efficiency. At the same time, it reduces the ineffective work of the compressor and lowers the energy consumption of the equipment.

[0010] The condenser assembly is equipped with a condensate channel connected to the water storage tank, and the condensate in the water storage tank can circulate within the channel. This design cleverly utilizes the low-temperature characteristics of the condensate produced by the evaporator. The condensate is low in temperature and rich in cooling capacity. When the condensate circulates through the condenser assembly, it can help the condenser assembly dissipate heat, reduce the surface temperature of the condenser assembly, improve the condensation efficiency of the refrigerant in the condenser assembly, and further optimize the stability of the refrigeration cycle. At the same time, no additional cooling medium is required. The condensate generated by the dehumidifier itself is used for auxiliary heat dissipation, which saves water resources and further reduces energy consumption, achieving the dual benefits of energy saving and high efficiency. In addition, the inlet and outlet of the condensate channel are connected to the water storage tank respectively to ensure a smooth circulation path and prevent condensate from stagnating and blocking the channel.

[0011] The top water tank is detachably mounted on the housing assembly. Compared to traditional bottom or side water storage designs, users can easily remove or place the top water tank without bending over or moving the entire dehumidifier, making operation much easier. The detachable structure also allows users to regularly clean the top water tank, removing scale and bacteria, preventing condensate from accumulating and developing odors, and ensuring hygiene. Furthermore, the top water tank, when mounted on the housing assembly, can precisely connect with the water outlet, ensuring that the condensate delivered by the first pump assembly can smoothly enter the top water tank, preventing leaks.

[0012] In one embodiment, the condensing assembly includes a heat exchange plate, a condensing pipe, fins, a flow pipe, and a second pump body. The heat exchange plate is disposed on the housing assembly and is adjacent to the evaporator. A gap is formed between the heat exchange plate and the evaporator. A portion of the heat insulation assembly is located within the gap. The condensing pipe passes through the heat exchange plate and extends reciprocally upward along the height direction of the heat exchange plate. One end of the condensing pipe is connected to the compressor, and the other end is connected to the evaporator via a throttling element. The fins are disposed on the heat exchange plate and located on the side away from the interval. There are multiple fins, which are spaced apart. The flow passage passes through the multiple fins and extends upwards and backwards along the height direction of the fins. One end of the second pump body is connected to the water storage tank, and the other end of the second pump body is connected to the flow passage. The flow passage is connected to the water storage tank.

[0013] The heat exchange plate is mounted on the shell assembly and adjacent to the evaporator, with a gap between them. Part of the insulation component is located within this gap. This design achieves a reasonable adjacent layout between the heat exchange plate and the evaporator, reducing installation space. At the same time, the gap provides a precise installation position for the insulation component, ensuring that the insulation component can fit tightly against the contact surface of the two, maximizing the blocking of heat transfer between the heat exchange plate and the evaporator, completely avoiding the problem of thermal short circuit, and ensuring the low-temperature cooling effect of the evaporator and the efficient heat release effect of the heat exchange plate.

[0014] The condenser pipe runs through the heat exchange plate and extends upwards and backwards along the height of the heat exchange plate. Compared with a straight pipe, this reciprocating extension design can significantly extend the flow path and residence time of the refrigerant in the condenser pipe, allowing the refrigerant to have a longer contact time and a larger contact area with the heat exchange plate and the outside air.

[0015] Multiple spaced fins significantly increase the overall heat dissipation area of ​​the condenser assembly.

[0016] The flow-through pipe is connected to the water storage tank to form a complete condensate circulation channel, ensuring that the condensate delivered by the second pump can flow smoothly through the flow-through pipe, absorb heat, and return smoothly to the water storage tank, avoiding condensate stagnation, scaling, or blockage in the pipe; at the same time, the design of the flow-through pipe passing through the fins does not require additional installation space, adapts to the compact structure of the condenser assembly, and takes into account both practicality and space utilization.

[0017] In one embodiment, the thermal insulation assembly includes a thermal insulation shell, a nano-aerogel vacuum interlayer, and a vacuum pump. The thermal insulation shell is disposed on the evaporator and the condenser assembly, and extends between the evaporator and the condenser assembly. The thermal insulation shell has a receiving cavity, the nano-aerogel vacuum interlayer is located in the receiving cavity, and the vacuum pump is disposed on the shell assembly and communicates with the receiving cavity. The vacuum pump is used to maintain the vacuum level in the receiving cavity.

[0018] The heat-insulating shell has a receiving cavity in which the nano-aerogel vacuum interlayer is located. This design provides a stable and sealed mounting carrier for the nano-aerogel vacuum interlayer.

[0019] As a core insulation component, the nano-aerogel vacuum interlayer has an extremely low thermal conductivity. Combined with the vacuum environment, it can completely block air conduction heat transfer. Its insulation effect is far superior to traditional insulation materials. It can maximize the blocking of conduction and radiation heat transfer between the evaporator and the condenser, ensuring that the two temperatures do not interfere with each other. This allows the evaporator to always maintain a low temperature dehumidification state, and the condenser to always maintain a high-efficiency heat dissipation state, thereby improving the heat exchange efficiency of the refrigeration components and reducing equipment energy consumption.

[0020] In one embodiment, the thermal insulation assembly further includes a miniature vacuum sensor disposed on the thermal insulation housing and located within the receiving cavity, the miniature vacuum sensor being used to detect the vacuum level of the receiving cavity.

[0021] The miniature vacuum sensor is mounted on the heat-insulating shell and located inside the containment cavity. It directly contacts the vacuum environment of the nano-aerogel vacuum interlayer and can detect the vacuum level inside the containment cavity in real time and accurately. Compared with external indirect detection, it avoids detection deviation and can accurately capture subtle changes in the vacuum level. It provides accurate and reliable signal support for the start and stop control of the vacuum pump and ensures that the nano-aerogel vacuum interlayer is always within the target vacuum level range.

[0022] In one embodiment, the thermal insulation assembly further includes a one-way valve disposed on the thermal insulation housing and partially located within the receiving cavity, and the vacuum pump is in communication with the one-way valve.

[0023] The one-way valve has a one-way conduction characteristic, allowing only the gas in the insulation housing cavity to flow to the vacuum pump through the one-way valve, which can completely block the reverse flow of gas—preventing outside air or residual gas in the vacuum pump pipeline from flowing back into the cavity after the vacuum pump stops, preventing the vacuum degree of the cavity from decaying rapidly, ensuring that the nano-aerogel vacuum interlayer is always within the target vacuum degree range, ensuring that its ultimate thermal insulation performance does not fail, and fundamentally consolidating the vacuum maintenance effect of the vacuum pump.

[0024] In one embodiment, the heat insulation housing includes a positioning housing, a locking housing, and an inner housing. The positioning housing is disposed on the evaporator and the condenser assembly and extends between the evaporator and the condenser assembly. The locking housing is disposed on the positioning housing. The inner housing is sandwiched between the positioning housing and the locking housing and has the receiving cavity.

[0025] As the basic load-bearing component of the insulation shell, the positioning shell can stably support the weight of components such as the locking shell, inner shell, and nano-aerogel vacuum interlayer in the inner shell cavity, preventing the overall displacement and loosening of the insulation shell due to equipment vibration, and ensuring the structural stability of the insulation shell. At the same time, its firm connection with the evaporator and condenser components can reduce the relative shaking between the insulation components and adjacent components, reduce component wear, and extend service life.

[0026] In one embodiment, the inner housing includes a first housing and a second housing, the first housing being disposed on the second housing, the middle portions of the first housing and the second housing forming the receiving cavity, the portions of the first housing and the second housing surrounding the receiving cavity being heat-sealed to form a heat-sealed area, the first housing and the second housing having an adhesive-sealed area surrounding the heat-sealed area, the adhesive-sealed area being bonded by sealant.

[0027] The first and second shells surround the cavity by heat sealing to form a heat-sealed area. The heat sealing process allows the contact surfaces of the two shells to melt and bond together, forming a tight and seamless sealing joint. As the first sealing barrier of the cavity, it can effectively block impurities such as external air, dust, and condensate from entering the cavity. At the same time, it prevents the vacuum environment inside the cavity from leaking due to poor sealing. It provides a basic vacuum guarantee for the ultimate thermal insulation performance of the nano-aerogel vacuum interlayer and works with the vacuum pump and one-way valve to maintain the stability of the vacuum level of the cavity.

[0028] The adhesive-sealed area surrounds the heat-sealed area, and the first and second shells are bonded together with sealant to form a dual sealing system of heat sealing and adhesive sealing. This effectively compensates for any minor gaps, air bubbles, or other sealing defects that may exist in the heat-sealed area, completely blocking the penetration path of gas and impurities, and further improving the sealing performance of the cavity. It is especially suitable for the vacuum maintenance requirements of the cavity, effectively preventing the infiltration of external air, avoiding the decay of the vacuum level in the cavity, and ensuring that the nano-aerogel vacuum interlayer is always in the optimal thermal insulation state. Together with the one-way valve and vacuum pump, it forms a more reliable vacuum maintenance protection.

[0029] In one embodiment, the first housing and the second housing are aluminum-plastic composite films, and the sealing areas of the first housing and the second housing are sealed with fluororubber.

[0030] Aluminum-plastic composite membranes are characterized by their thinness and lightweight. Compared to traditional metal and rigid plastic shells, the use of this material for the first and second shells can significantly reduce the overall thickness and weight of the inner shell. This perfectly fits the compact layout where the insulation shell is sandwiched between the positioning and locking shells, without occupying additional installation space. It also meets the design requirements of miniaturization and integration of the dehumidifier. In addition, aluminum-plastic composite membranes have good flexibility and can be flexibly adapted to the enclosure structure of the first and second shells, facilitating heat sealing and separate assembly, reducing production and assembly difficulty, and reducing the risk of shell damage caused by equipment vibration.

[0031] Fluororubber has good adhesive compatibility with aluminum-plastic composite film, and can form a strong adhesive bond with the aluminum-plastic composite film surface of the first shell and the second shell.

[0032] In one embodiment, the first housing and the second housing are sealed by the following method: Place the nano-aerogel vacuum interlayer in the designated area of ​​the first shell, cover the nano-aerogel vacuum interlayer with the second shell, and align the first and second shells around their perimeters. Remove excess nano-aerogel vacuum interlayer from the edges, wipe the sealing surface with anhydrous ethanol to remove oil and dust, and let it dry for later use; Heat sealing operation: A pulse heat sealing machine is used. The heat sealing temperature is set to 120-150℃, the heat sealing pressure is 0.3-0.5MPa, and the heat sealing time is 3-5s. Continuous heat sealing is performed on the four sides of the first and second shells. The heat sealing width is controlled at 3-6mm to ensure that there are no bubbles, wrinkles, or leaks at the heat sealing edge. After heat sealing, the shell is allowed to cool naturally to room temperature to form the first sealing barrier. At the same time, the outer side of the heat sealing area is 2-4mm away from the outermost edge of the first and second shells. Sealing process: Use a micro dispensing machine to evenly apply a ring of fluororubber sealant along the outer side of the heat-sealed edge. The thickness of the sealant should be 0.2-0.3mm and the width should be 2-4mm. Ensure that the sealant layer fully covers the edge of the heat-sealed edge and the joint of the sealing film, without any gaps or bubbles. Curing and molding: The coated interlayer is placed in a room temperature environment for curing for at least 24 hours to ensure that the fluororubber layer is completely cured and tightly bonded to the first and second shells, forming a second flexible sealing barrier to prevent trace amounts of gas from seeping in from the heat-sealed gaps.

[0033] The first step involves placing the nano-aerogel vacuum interlayer in the designated area of ​​the first housing and aligning it around the perimeter after the second housing is closed. This ensures that the nano-aerogel vacuum interlayer is precisely positioned within the cavity enclosed by the first and second housings, preventing misalignment that could damage the interlayer edges during heat sealing and adhesive sealing processes. It also ensures that the perimeters of the two housings are aligned, providing a flat and aligned reference for subsequent heat sealing and adhesive sealing operations. This prevents uneven sealing edges and gaps caused by housing misalignment, ensuring a tight seal.

[0034] Wiping the sealing surface with anhydrous ethanol to remove oil and dust, and then letting it dry, can thoroughly remove impurities from the sealing surface, preventing impurities from causing bubbles and wrinkles during heat sealing, and problems such as weak adhesion and delamination during glue sealing.

[0035] After heat sealing, allow it to cool naturally to room temperature to avoid deformation and cracking of the heat-sealed edge caused by artificial cooling, and ensure that the heat-sealed layer is fully cured and set.

[0036] A micro dispensing machine is used to evenly apply fluororubber sealant along the outer side of the heat-sealed edge, enabling precise control of the adhesive layer. The parameters of 0.2-0.3mm adhesive thickness and 2-4mm adhesive width ensure sufficient bonding strength and sealing thickness while avoiding waste due to excessive thickness and sealing failure due to insufficient thickness. At the same time, the adhesive layer fully covers the edge of the heat-sealed edge and the joint of the shell, without any gaps or air bubbles. It can perfectly compensate for any tiny gaps that may exist in the heat-sealed area and the minor deformation gaps caused by thermal expansion and contraction. Together with the heat-sealed area, it forms a double seal, completely preventing the infiltration of trace amounts of gas.

[0037] In one embodiment, the housing assembly includes an outer shell assembly, a duct housing, and a liquid level detection unit. The duct housing is disposed on the outer shell assembly and located inside the outer shell assembly. The liquid level detection unit is disposed on the outer shell assembly and located at the top of the outer shell assembly. The fan assembly is disposed on the duct housing. The cooling assembly, the water outlet, and the first pump assembly are disposed on the outer shell assembly. The top water tank is provided with a recessed groove. The top water tank is detachably disposed on the outer shell assembly, and the recessed groove can be adapted to the liquid level detection unit.

[0038] The outer casing provides precise installation positions for components such as the air duct housing, liquid level detection unit, and refrigeration components, eliminating the need for additional mounting brackets, simplifying the overall assembly process, improving the integration level of the dehumidifier, reducing production assembly difficulty, and facilitating mass production. In addition, its top is adapted for detachable installation of the top water tank, perfectly meeting the overall structural design requirements.

[0039] The recessed groove of the top water tank is precisely matched with the liquid level detection unit, which ensures that the liquid level detection unit can stably contact the condensate in the water tank after the top water tank is installed in place, avoiding detection failure due to water tank misalignment.

[0040] In one embodiment, the first pump body assembly includes a first pump body and a first valve body, the first pump body and the first valve body are disposed on the housing assembly, one end of the first pump body is connected to the water storage tank, and the other end of the first pump body, the first valve body and the water outlet are connected in sequence.

[0041] The first pump body, as the core power component for condensate delivery, is connected to the water storage tank at one end. It can accurately extract the condensate generated by the evaporator collected in the water storage tank, providing continuous and stable power for condensate delivery and avoiding the inability to deliver condensate and the overflow and leakage of the water storage tank due to lack of power.

[0042] The first valve body is connected in series between the first pump body and the outlet component, which can precisely control the flow of condensate. When the top water tank is installed and condensate needs to be stored, the valve body can be opened to allow the condensate to flow smoothly into the top water tank through the outlet component.

[0043] In one embodiment, the top water tank includes a tank body, a second valve body, and a first water level detection element. The tank body is provided with a water-containing tank. The second valve body is disposed on the tank body and located at the bottom of the tank body. The second valve body can open or close the water-containing tank. The second valve body is adapted to the water outlet. The tank body is provided with a limiting groove that communicates with the water-containing tank. The first water level detection element is located within the limiting groove and can float within the range defined by the limiting groove.

[0044] The cabinet is equipped with a water tank specifically for storing condensate delivered through the water outlet. The volume of the water tank can be precisely matched to the condensate production rate of the dehumidifier, which can meet the secondary use of condensate within a certain period without making the top water tank bulky and taking up too much space due to excessive volume. At the same time, the inner wall of the water tank can be treated with a smooth anti-corrosion coating to prevent condensate residue, bacterial growth or corrosion of the cabinet, ensuring the cleanliness of the condensate and extending the service life of the cabinet.

[0045] The limiting groove in the housing is connected to the water tank and can specifically accommodate the first water level detection element and limit its floating range. This prevents the first water level detection element from deviating from its detection position due to the shaking of condensate in the water tank or slight displacement of the housing, ensuring that the first water level detection element is always in a stable detection state and providing a guarantee for accurate water level detection. At the same time, the limiting groove can prevent the detection element from colliding with the inner wall of the water tank, the second valve body and other components, reducing wear on the detection element and extending its service life.

[0046] In one embodiment, a second water level detection element is further included, which is located inside the water storage tank and is used to detect the water level in the water storage tank.

[0047] The second water level detection element is specially installed inside the water storage tank. It can directly and in real time detect changes in the liquid level of condensate in the water storage tank, filling the blind spot of the original monitoring only by the first water level detection element in the top water tank. As the initial collection component of condensate, the water level change of the water storage tank is directly related to the operational safety of the first pump. This element can accurately capture the water level of the water storage tank, avoiding equipment failure due to the failure to detect abnormal water level in the water storage tank, and providing the first monitoring guarantee for condensate collection and transportation.

[0048] A second aspect of this application discloses a dehumidification method, which includes the following steps: The fan assembly starts working and the compressor starts cooling. The air input through the air inlet is condensed by the evaporator to obtain condensate water, which enters the water storage tank. During the refrigeration process, the liquid level in the water tank is monitored. When the liquid level in the water tank is higher than the first preset value, the second pump is started to transport the liquid in the water tank to the flow pipeline, and after passing through the fins, it re-enters the water tank. The water level in the storage tank continues to rise. When the water level in the storage tank is higher than the second preset value, the first pump assembly is started to pump the water in the storage tank to the top water tank. When the water level in the storage tank is lower than the first preset value, the first pump assembly is stopped. After dehumidification is complete, the second pump body is stopped, and all the water in the water storage tank is transported to the top water tank through the first pump body assembly.

[0049] The fan assembly and compressor start simultaneously, forming a coordinated linkage between airflow circulation and refrigeration and dehumidification. The fan assembly can quickly draw in humid air from the outside through the air inlet, ensuring that the humid air flows continuously and stably through the evaporator. After the compressor starts, it drives the refrigeration assembly to run, so that the evaporator can quickly reach a low temperature refrigeration state. The two work together to quickly achieve condensation and dehumidification of humid air, shorten the dehumidification start-up time, improve dehumidification efficiency, and quickly improve the ambient humidity.

[0050] The second pump is activated when the liquid level in the storage tank exceeds a first preset value, achieving automated control of circulation once the liquid level reaches the target, without manual intervention. The second pump transports the condensate in the storage tank to the flow pipe, flows through the fins, and then returns to the storage tank, realizing the recycling of the condensate. The low-temperature condensate absorbs heat from the fins, assisting the condenser components in heat dissipation, further improving the refrigerant condensation efficiency, and indirectly enhancing the overall dehumidification performance of the dehumidifier.

[0051] Two preset liquid level values ​​are set to form a hierarchical control logic. The second preset value is higher than the first preset value to ensure that the condensate is recycled before being stored and transported, taking into account both energy saving and storage needs. When the liquid level is higher than the second preset value, the first pump assembly is started, and when it is lower than the first preset value, it is stopped. This can precisely control the liquid level in the water storage tank to always be within a safe range, avoiding both overflow of condensate and the idling of the first pump assembly due to low liquid level, thus achieving automated and precise control.

[0052] In one embodiment, the dehumidification method further includes the following steps: The vacuum level inside the containment cavity of the heat insulation shell is fed back by a miniature vacuum sensor. When the vacuum level inside the containment cavity is lower than the preset value, the vacuum pump is activated. The operation of the vacuum pump makes the vacuum level inside the containment cavity lower than the preset value.

[0053] By continuously feeding back the vacuum level inside the insulation housing cavity through a miniature vacuum sensor, the working environment status of the nano-aerogel vacuum interlayer can be monitored in real time. This allows for precise detection of subtle vacuum level decreases, preventing the insulation performance from deteriorating due to undetected vacuum level loss. It provides real-time monitoring assurance for the efficient operation of the insulation components and fills the gap in the original dehumidification process where vacuum level monitoring was not available.

[0056] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0059] The dehumidifier and dehumidification method of some embodiments of the present invention are described below with reference to the accompanying drawings. Example 1

[0060] like Figures 1 to 11 As shown, this embodiment discloses a dehumidifier, which includes: The housing assembly 1 has a mounting cavity 101, an air inlet 102 and an air outlet 103, and a water storage tank 104 at the bottom of the mounting cavity 101. Fan assembly 2 is mounted on housing assembly 1 and located in mounting cavity 101. Fan assembly 2 is used to transport air entering through air inlet 102 to air outlet 103. The refrigeration assembly 3 includes a compressor 31, an evaporator 32, a condenser assembly 33, and a heat insulation assembly 34. The compressor 31, evaporator 32, and condenser assembly 33 are mounted on the housing assembly 1 and located within the mounting cavity 101. The evaporator 32 is adjacent to the air inlet 102 and is connected to the compressor 31. The compressor 31 is connected to the condenser assembly 33. The condenser assembly 33 is connected to the evaporator 32 via a throttling element and is adjacent to the evaporator 32. The heat insulation assembly 34 is located between the evaporator 32 and the condenser assembly 33 to block heat transfer between them. The water storage tank 104 is located below the evaporator 32 and is used to collect the condensate generated during its operation. The condenser assembly 33 is provided with a condensate channel. The inlet and outlet of the condensate channel are respectively connected to the water storage tank 104, and the liquid in the water storage tank 104 can circulate in the condensate channel. Water outlet 4 is disposed on the housing assembly 1 and located at the top of the housing assembly 1; The first pump body assembly 5 has one end connected to the water storage tank 104 and the other end connected to the water outlet 4; The top water tank 6 is detachably mounted on the housing assembly 1. When mounted on the housing assembly 1, the top water tank 6 can communicate with the water outlet 4.

[0061] The dehumidifier disclosed in this application achieves an orderly layout of components through the integrated design of the mounting cavity 101: the shell assembly 1 has an independent mounting cavity 101, in which the core components such as the fan assembly 2, the refrigeration assembly 3, and the first pump body assembly 5 are all integrated, thereby achieving an orderly arrangement of the components, avoiding mutual interference between the components, and significantly reducing the overall volume of the dehumidifier.

[0062] The heat insulation component 34, located between the adjacent condenser assembly 33 and evaporator 32, can effectively block heat transfer between the evaporator 32 and the condenser assembly 33, preventing the cooling capacity generated by the evaporator 32 from being offset by the heat dissipated by the condenser assembly 33. At the same time, it prevents the heat from the condenser assembly 33 from penetrating to the surface of the evaporator 32, ensuring that the evaporator 32 always maintains a low temperature and the condenser assembly 33 always maintains a high-efficiency heat release state. This improves the heat exchange efficiency of the refrigerant, makes the refrigeration cycle smoother, and ultimately achieves a significant improvement in dehumidification efficiency. Meanwhile, it reduces the ineffective work of the compressor 31 and lowers the energy consumption of the equipment.

[0063] The condenser assembly 33 is equipped with a condensate channel connected to the water storage tank 104, and the condensate in the water storage tank 104 can circulate in the channel. This design cleverly utilizes the low-temperature characteristics of the condensate produced by the evaporator 32. The condensate is low in temperature and rich in cooling capacity. When the condensate circulates through the condenser assembly 33, it can help the condenser assembly 33 dissipate heat, reduce the surface temperature of the condenser assembly 33, improve the condensation efficiency of the refrigerant in the condenser assembly 33, and further optimize the stability of the refrigeration cycle. At the same time, no additional cooling medium is needed. The condensate generated by the dehumidifier itself is used to achieve auxiliary heat dissipation, which saves water resources and further reduces energy consumption, achieving the dual benefits of energy saving and high efficiency. In addition, the liquid inlet and liquid outlet of the condensate channel are connected to the water storage tank 104 respectively to ensure smooth circulation and avoid condensate stagnation and blockage in the channel.

[0064] The top water tank 6 is detachably mounted on the housing assembly 1. Compared to the traditional bottom and side water storage design, users do not need to bend over or move the entire dehumidifier when taking out or removing the top water tank 6, making operation more effortless. The detachable structure makes it easy for users to clean the top water tank 6 regularly, removing scale and bacteria from the tank and preventing odors from long-term storage of condensate, thus ensuring hygiene. At the same time, when the top water tank 6 is mounted on the housing assembly 1, it can be precisely connected to the water outlet 4, ensuring that the condensate delivered by the first pump assembly 5 can be smoothly injected into the top water tank 6, preventing leakage.

[0065] like Figures 7 to 11 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the condensing assembly 33 includes a heat exchange plate 331, a condensing pipe 332, fins 333, a flow pipe 334, and a second pump body 335. The heat exchange plate 331 is disposed on the housing assembly 1. The heat exchange plate 331 is adjacent to the evaporator 32, and a gap is formed between the heat exchange plate 331 and the evaporator 32. A portion of the heat insulation assembly 34 is located within the gap. The condensing pipe 332 passes through the heat exchange plate 331 and extends upward and backward along the height direction of the heat exchange plate 331. One end of the condensing pipe 332 is connected to the compressor 31, and the other end is connected to the evaporator 32 via a throttling element. Fins 333 are disposed on heat exchange plate 331 and located on the side away from the interval. There are multiple fins 333, which are spaced apart. Flow pipe 334 passes through multiple fins 333 and extends upwards and backwards along the height direction of the fins 333. One end of the second pump body 335 is connected to the water storage tank 104, and the other end of the second pump body 335 is connected to the flow pipe 334. Flow pipe 334 is connected to the water storage tank 104.

[0066] The heat exchange plate 331 is mounted on the shell assembly 1 and is adjacent to the evaporator 32, with a gap between them. Part of the heat insulation component 34 is located within this gap. This design achieves a reasonable adjacent layout between the heat exchange plate 331 and the evaporator 32, which can reduce the installation space. At the same time, the gap provides a precise installation position for the heat insulation component 34, ensuring that the heat insulation component 34 can fit tightly against the contact surface of the two, maximizing the blocking of heat transfer between the heat exchange plate 331 and the evaporator 32, completely avoiding the problem of thermal short circuit, and ensuring the low-temperature cooling effect of the evaporator 32 and the efficient heat release effect of the heat exchange plate 331.

[0067] The condenser pipe 332 passes through the heat exchange plate 331 and extends upwards and backwards along the height of the heat exchange plate 331. Compared with a straight pipe, this reciprocating extension design can significantly extend the flow path and residence time of the refrigerant in the condenser pipe 332, allowing the refrigerant to have a longer contact time and a larger contact area with the heat exchange plate 331 and the outside air.

[0068] Multiple spaced fins 333 significantly increase the overall heat dissipation area of ​​the condensation assembly 33.

[0069] The flow passage 334 is connected to the water storage tank 104 to form a complete condensate circulation channel, ensuring that the condensate transported by the second pump body 335 can flow smoothly through the flow passage 334, absorb heat and flow back smoothly to the water storage tank 104, avoiding condensate stagnation, scaling or blockage in the passage; at the same time, the design of the flow passage 334 passing through the fins 333 does not require additional installation space, adapts to the compact structure of the condenser assembly 33, and takes into account both practicality and space utilization.

[0070] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heat insulation component 34 includes a heat insulation shell 341, a nano-aerogel vacuum interlayer and a vacuum pump. The heat insulation shell 341 is disposed on the evaporator 32 and the condenser component 33. The heat insulation shell 341 extends between the evaporator 32 and the condenser component 33. The heat insulation shell 341 is provided with a receiving cavity. The nano-aerogel vacuum interlayer is located in the receiving cavity. The vacuum pump is disposed on the shell component 1 and communicates with the receiving cavity. The vacuum pump is used to maintain the vacuum level in the receiving cavity.

[0071] The heat insulation shell 341 has a receiving cavity, within which the nano-aerogel vacuum jacket is located. This design provides a stable and sealed mounting carrier for the nano-aerogel vacuum jacket. As the core heat insulation component, the nano-aerogel vacuum jacket has an extremely low thermal conductivity. Combined with the vacuum environment, it can completely block air conduction heat transfer. Its heat insulation effect is far superior to traditional heat insulation materials. It can maximize the blocking of conduction and radiation heat transfer between the evaporator 32 and the condenser assembly 33, ensuring that their temperatures do not interfere with each other. This allows the evaporator 32 to always maintain a low-temperature dehumidification state, and the condenser assembly 33 to always maintain a highly efficient heat dissipation state, thereby improving the heat exchange efficiency of the refrigeration assembly 3 and reducing equipment energy consumption.

[0072] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heat insulation component 34 also includes a miniature vacuum sensor 342, which is disposed on the heat insulation housing 341 and located in the receiving cavity, and is used to detect the vacuum degree of the receiving cavity.

[0073] The miniature vacuum sensor 342 is mounted on the heat insulation housing 341 and located inside the containment cavity. It directly contacts the vacuum environment of the nano-aerogel vacuum interlayer and can detect the vacuum level inside the containment cavity in real time and accurately. Compared with external indirect detection, it avoids detection deviation and can accurately capture subtle changes in the vacuum level. It provides accurate and reliable signal support for the start and stop control of the vacuum pump and ensures that the nano-aerogel vacuum interlayer is always within the target vacuum level range.

[0074] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the heat insulation component 34 also includes a one-way valve 343, which is disposed on the heat insulation housing 341 and partially located in the receiving cavity, and the vacuum pump is connected to the one-way valve 343.

[0075] The one-way valve 343 has a one-way conduction characteristic, allowing only the gas in the containment cavity of the heat insulation shell 341 to flow to the vacuum pump through the one-way valve 343. This completely blocks the reverse flow of gas, preventing outside air or residual gas in the vacuum pump pipeline from flowing back into the containment cavity after the vacuum pump stops. This prevents the vacuum degree of the containment cavity from decaying rapidly, ensuring that the nano-aerogel vacuum interlayer is always within the target vacuum degree range, ensuring that its ultimate heat insulation performance does not fail, and fundamentally consolidating the vacuum maintenance effect of the vacuum pump.

[0076] like Figure 10 and Figure 11As shown, in addition to the features of the above embodiments, this embodiment further defines that: the heat insulation shell 341 includes a positioning shell 3411, a locking shell 3412 and an inner shell 3413. The positioning shell 3411 is disposed on the evaporator 32 and the condenser assembly 33 and extends between the evaporator 32 and the condenser assembly 33. The locking shell 3412 is disposed on the positioning shell 3411. The inner shell 3413 is sandwiched between the positioning shell 3411 and the locking shell 3412. The inner shell 3413 is provided with a receiving cavity.

[0077] As the basic load-bearing component of the insulation shell 341, the positioning shell 3411 can stably support the weight of components such as the locking shell 3412, the inner shell 3413, and the nano-aerogel vacuum interlayer in the cavity of the inner shell 3413, preventing the insulation shell 341 from shifting or loosening due to vibration during equipment operation, thus ensuring the structural stability of the insulation shell 341. At the same time, its firm connection with the evaporator 32 and the condenser assembly 33 can reduce the relative shaking between the insulation assembly 34 and adjacent components, reduce component wear, and extend service life.

[0078] like Figure 10 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines: the inner shell 3413 includes a first shell 34131 and a second shell 34132, the first shell 34131 is disposed on the second shell 34132, the middle part of the first shell 34131 and the second shell 34132 surrounds to form a receiving cavity, the portion of the first shell 34131 and the second shell 34132 surrounding the receiving cavity is heat-sealed to form a heat-sealed area, the first shell 34131 and the second shell 34132 are provided with an adhesive sealing area surrounding the heat-sealed area, and the adhesive sealing area is bonded by sealant.

[0079] The first housing 34131 and the second housing 34132 partially heat-seal the cavity to form a heat-sealed area. The heat-sealing process allows the contact surfaces of the two to melt and adhere together, forming a tight and seamless sealing joint. As the first sealing barrier of the cavity, it can effectively block external air, dust, condensate and other impurities from entering the cavity, while preventing the vacuum environment inside the cavity from leaking due to poor sealing. It provides a basic vacuum guarantee for the ultimate thermal insulation performance of the nano-aerogel vacuum interlayer, and works with the vacuum pump and one-way valve 343 to maintain the stability of the vacuum level of the cavity.

[0080] The adhesive-sealed area surrounds the heat-sealed area, and the first housing 34131 and the second housing 34132 are bonded together with sealant to form a dual sealing system of heat sealing and adhesive sealing. This can effectively compensate for sealing defects such as tiny gaps and air bubbles that may exist in the heat-sealed area, completely block the penetration path of gas and impurities, and further improve the sealing performance of the cavity. In particular, it is suitable for the vacuum maintenance requirements of the cavity, effectively preventing the infiltration of external air, avoiding the decay of the vacuum degree of the cavity, and ensuring that the nano-aerogel vacuum interlayer is always in the optimal heat insulation state. Together with the one-way valve 343 and the vacuum pump, it forms a more reliable vacuum maintenance protection.

[0081] In addition to the features of the above embodiments, this embodiment further specifies that: the first housing 34131 and the second housing 34132 are aluminum-plastic composite films, and the sealing areas of the first housing 34131 and the second housing 34132 are sealed with fluororubber.

[0082] The aluminum-plastic composite membrane is characterized by its thinness and lightweight. Compared to traditional metal and rigid plastic shells, the use of this material for the first shell 34131 and the second shell 34132 significantly reduces the overall thickness and weight of the inner shell 3413. This perfectly fits the compact layout of the heat insulation shell 341 sandwiched between the positioning shell 3411 and the locking shell 3412, without occupying additional installation space. It also aligns with the overall miniaturization and integration requirements of the dehumidifier. Furthermore, the aluminum-plastic composite membrane has excellent flexibility, allowing it to adapt flexibly to the enclosure structure of the first shell 34131 and the second shell 34132. This facilitates heat sealing and modular assembly, reducing production and assembly difficulties, and minimizing the risk of shell damage due to equipment vibration. Fluororubber has excellent adhesive compatibility with the aluminum-plastic composite membrane, forming a strong adhesive bond with the surfaces of the aluminum-plastic composite membrane in the first shell 34131 and the second shell 34132.

[0083] In addition to the features of the above embodiments, this embodiment further specifies that the first housing 34131 and the second housing 34132 are sealed by the following method: The nano-aerogel vacuum interlayer is placed in the designated area of ​​the first shell 34131, and the second shell 34132 is placed on top of the nano-aerogel vacuum interlayer. The first shell 34131 and the second shell 34132 are then aligned around each other. Remove excess nano-aerogel vacuum interlayer from the edges, wipe the sealing surface with anhydrous ethanol to remove oil and dust, and let it dry for later use; Heat sealing operation: A pulse heat sealing machine is used, with the heat sealing temperature set at 120-150℃, the heat sealing pressure at 0.3-0.5MPa, and the heat sealing time at 3-5s. Continuous heat sealing is performed around the first housing 34131 and the second housing 34132, with the heat sealing width controlled at 3-6mm. Ensure that there are no bubbles, wrinkles, or leaks at the heat sealing edge. After heat sealing, allow it to cool naturally to room temperature to form the first sealing barrier. At the same time, the distance between the outer side of the heat sealing area and the outermost edge of the first housing 34131 and the second housing 34132 is 2-4mm. Sealing process: Use a micro dispensing machine to evenly apply a ring of fluororubber sealant along the outer side of the heat-sealed edge. The thickness of the sealant should be 0.2-0.3mm and the width should be 2-4mm. Ensure that the sealant layer fully covers the edge of the heat-sealed edge and the joint of the sealing film, without any gaps or bubbles. Curing and molding: The coated interlayer is placed in a room temperature environment for curing for at least 24 hours to ensure that the fluororubber layer is completely cured and tightly bonded to the first shell 34131 and the second shell 34132 to form a second flexible sealing barrier, preventing trace amounts of gas from seeping in from the heat-sealed gaps.

[0084] The first step involves placing the nano-aerogel vacuum interlayer in the designated area of ​​the first housing 34131 and aligning it with the second housing 34132 after it is closed. This ensures that the nano-aerogel vacuum interlayer is precisely located within the cavity enclosed by the first housing 34131 and the second housing 34132, preventing misalignment that could damage the interlayer edges during heat sealing and adhesive sealing processes. At the same time, ensuring that the two housings are aligned provides a flat and aligned reference for subsequent heat sealing and adhesive sealing operations, preventing uneven sealing edges and gaps caused by housing misalignment, and ensuring a good seal.

[0085] Wiping the sealing surface with anhydrous ethanol to remove oil and dust, and then letting it dry, can thoroughly remove impurities from the sealing surface, preventing impurities from causing bubbles and wrinkles during heat sealing, and problems such as weak adhesion and delamination during glue sealing.

[0086] After heat sealing, allow it to cool naturally to room temperature to avoid deformation and cracking of the heat-sealed edge caused by artificial cooling, and ensure that the heat-sealed layer is fully cured and set.

[0087] A micro dispensing machine is used to evenly apply fluororubber sealant along the outer side of the heat-sealed edge, enabling precise control of the adhesive layer. The parameters of 0.2-0.3mm adhesive thickness and 2-4mm adhesive width ensure sufficient bonding strength and sealing thickness while avoiding waste due to excessive thickness and sealing failure due to insufficient thickness. At the same time, the adhesive layer fully covers the edge of the heat-sealed edge and the joint of the shell, without any gaps or air bubbles. It can perfectly compensate for any tiny gaps that may exist in the heat-sealed area and the minor deformation gaps caused by thermal expansion and contraction. Together with the heat-sealed area, it forms a double seal, completely preventing the infiltration of trace amounts of gas.

[0088] like Figure 5 , Figure 6and Figure 12 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes an outer shell assembly 11, an air duct housing 12 and a liquid level detection unit 13. The air duct housing 12 is disposed on the outer shell assembly 11 and located inside the outer shell assembly 11. The liquid level detection unit 13 is disposed on the outer shell assembly 11 and located at the top of the outer shell assembly 11. The fan assembly 2 is disposed on the air duct housing 12. The cooling assembly 3, the water outlet 4 and the first pump body assembly 5 are disposed on the outer shell assembly 11. The top water tank 6 is provided with a recessed groove. The top water tank 6 is detachably disposed on the outer shell assembly 11 and the recessed groove can be adapted to the liquid level detection unit 13.

[0089] The outer casing assembly 11 provides precise installation positions for components such as the air duct housing 12, liquid level detection unit 13, and refrigeration assembly 3, eliminating the need for additional installation brackets, simplifying the overall assembly process, improving the integration level of the dehumidifier, reducing production assembly difficulty, and facilitating mass production. In addition, its top is adapted to the detachable installation of the top water tank 6, perfectly meeting the overall structural design requirements.

[0090] The recessed groove of the top water tank 6 is precisely matched with the liquid level detection unit 13, which can ensure that after the top water tank 6 is installed in place, the liquid level detection unit 13 can stably contact the condensate in the water tank, avoiding detection failure due to water tank displacement.

[0091] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the first pump body assembly 5 includes a first pump body 51 and a first valve body 52, the first pump body 51 and the first valve body 52 are disposed on the housing assembly 1, one end of the first pump body 51 is connected to the water storage tank 104, and the other end of the first pump body 51, the first valve body 52 and the water outlet 4 are connected in sequence.

[0092] The first pump body 51 serves as the core power component for condensate delivery. One end is connected to the water storage tank 104, which can accurately extract the condensate generated by the evaporator 32 collected in the water storage tank 104, providing continuous and stable power for condensate delivery and preventing the condensate from failing to be delivered due to lack of power and the water storage tank 104 from overflowing and leaking.

[0093] The first valve body 52 is connected in series between the first pump body 51 and the water outlet 4, which can precisely control the flow of condensate. When the top water tank 6 is installed and needs to store condensate, the valve body can be opened to allow the condensate to flow smoothly into the top water tank 6 through the water outlet 4.

[0094] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the top water tank 6 includes a tank body 61, a second valve body 62 and a first water level detection element 63. The tank body 61 is provided with a water-containing tank 601. The second valve body 62 is disposed on the tank body 61 and is located at the bottom of the tank body 61. The second valve body 62 can open or close the water-containing tank 601. The second valve body 62 is adapted to the water outlet 4. The tank body 61 is provided with a limiting groove 602, which communicates with the water-containing tank 601. The first water level detection element 63 is located in the limiting groove 602 and can float within the range limited by the limiting groove 602.

[0095] The housing 61 is equipped with a water tank 601, which is specifically used to store the condensate delivered by the water outlet 4. The volume of the water tank 601 can be precisely matched to the condensate production rate of the dehumidifier, which can meet the secondary use of condensate within a certain period of time, without making the top water tank 6 bulky and taking up too much space due to excessive volume. At the same time, the inner wall of the water tank 601 can be treated with smooth anti-corrosion to avoid condensate residue, bacterial growth or corrosion of the housing 61, ensuring the cleanliness of the condensate and extending the service life of the housing 61.

[0096] The limiting groove 602 provided in the housing 61 is connected to the water tank 601 and can specifically accommodate the first water level detection element 63 and limit its floating range. This prevents the first water level detection element 63 from deviating from its detection position due to the shaking of condensed water in the water tank 601 or slight displacement of the housing 61, ensuring that the first water level detection element 63 is always in a stable detection state and providing a guarantee for accurate water level detection. At the same time, the limiting groove 602 can prevent the detection element from colliding with the inner wall of the water tank 601, the second valve body 62 and other components, reducing wear on the detection element and extending its service life.

[0097] In addition to the features of the above embodiments, this embodiment further includes a second water level detection element, which is located inside the water storage tank 104 and is used to detect the water level inside the water storage tank 104.

[0098] The second water level detection element is specially installed in the water storage tank 104. It can directly and in real time detect the changes in the liquid level of the condensate in the water storage tank 104. This fills the blind spot of the original monitoring only by the first water level detection element in the top water tank 6. As the initial collection component of condensate, the water level change of the water storage tank 104 is directly related to the operational safety of the first pump body 51. This element can accurately capture the water level of the water storage tank 104, avoiding equipment failure due to the failure to detect abnormal water level in the water storage tank, and providing the first monitoring guarantee for the collection and transportation of condensate. Example 2

[0099] This embodiment discloses a dehumidification method, which includes the following steps: The fan assembly 2 is started to work and the compressor 31 is started to cool. The air input from the air inlet 102 is condensed through the evaporator 32 to obtain condensate water, which enters the water storage tank 104. During the cooling process, the liquid level in the water storage tank 104 is detected. When the liquid level in the water storage tank 104 is higher than the first preset value, the second pump body 335 is started to transport the liquid in the water storage tank 104 to the overflow pipe 334, and after passing through the fins 333, it re-enters the water storage tank 104. The liquid level in the water storage tank 104 continues to rise. When the liquid level in the water storage tank 104 is higher than the second preset value, the first pump assembly 5 is started to pump the water in the water storage tank 104 to the top water tank 6. When the water level in the water storage tank 104 is lower than the first preset value, the first pump assembly 5 is stopped. After dehumidification is completed, the second pump body 335 is stopped, and all the water in the water storage tank 104 is transported to the top water tank 6 through the first pump body assembly 5.

[0100] The fan assembly 2 and compressor 31 are started simultaneously to form a coordinated linkage of airflow circulation and refrigeration and dehumidification. The fan assembly 2 can quickly draw in the outside humid air into the equipment through the air inlet 102, ensuring that the humid air flows continuously and stably through the evaporator 32. After the compressor 31 starts, it drives the refrigeration assembly 3 to run, so that the evaporator 32 can quickly reach a low temperature refrigeration state. The two work together to quickly achieve condensation and dehumidification of humid air, shorten the dehumidification start-up time, improve dehumidification efficiency, and quickly improve the ambient humidity.

[0101] The second pump body 335 is triggered to start when the liquid level in the water storage tank 104 is higher than the first preset value, realizing automatic control of circulation as soon as the liquid level reaches the standard, without manual intervention. The second pump body 335 transports the condensate in the water storage tank 104 to the flow pipe 334, flows through the fins 333 and then flows back to the water storage tank 104, realizing the recycling of condensate. The low-temperature condensate absorbs the heat on the fins 333, assists the condensation component 33 in heat dissipation, further improves the refrigerant condensation efficiency, and indirectly enhances the overall dehumidification performance of the dehumidifier.

[0102] Two preset liquid level values ​​are set to form a hierarchical control logic. The second preset value is higher than the first preset value, ensuring that the condensate is recycled before being stored and transported, taking into account both energy saving and storage needs. When the liquid level is higher than the second preset value, the first pump assembly 5 is started, and when it is lower than the first preset value, it stops. This can precisely control the liquid level in the water storage tank 104 to always be within a safe range, avoiding both overflow of condensate and the idling of the first pump assembly 5 due to excessively low liquid level, thus achieving automated and precise control.

[0103] In addition to the features of the above embodiments, this embodiment further specifies that the dehumidification method also includes the following steps: The vacuum level inside the containment cavity of the heat insulation housing 341 is fed back by the miniature vacuum sensor 342. When the vacuum level inside the containment cavity is lower than the preset value, the vacuum pump is started. The operation of the vacuum pump makes the vacuum level inside the containment cavity lower than the preset value.

[0104] By continuously feeding back the vacuum level inside the cavity of the insulation housing 341 through the miniature vacuum sensor 342, the working environment status of the nano-aerogel vacuum interlayer can be monitored in real time, and the slight decrease in vacuum level can be accurately captured. This avoids the thermal insulation performance from being degraded due to the failure to detect the loss of vacuum level control, and provides real-time monitoring guarantee for the efficient operation of the thermal insulation component 34, filling the gap of no vacuum level monitoring in the original dehumidification process.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above embodiments are merely examples of several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent.

[0107] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these modifications and improvements are all within the scope of protection of this invention.

[0108] Therefore, the scope of protection of this invention patent shall be determined by the appended claims.
