In a specific season, the air humidity in the room may be too low or too high, resulting in a reduction in comfort when a user lives, and the above-described problem can be solved by providing an air humidity adjusting device in the room to adjust the air humidity. The indoor air humidity adjusting device can be a dehumidifier, a humidifier or a humidity controller integrating dehumidification/humidification functions. In the indoor air humidity conditioning apparatus, the desorption assembly is the most central component. Taking a dehumidifier as an example, in the dehumidification process, a dehumidification fan works, air with higher indoor humidity enters the equipment and flows through the desorption element, water molecules in the air are adsorbed by the desorption element after contacting with the desorption element, the water molecule content in the air is reduced, and drier air is discharged into the room, so that the humidity of indoor air is reduced. Meanwhile, along with more and more moisture that desorption component desorbed, the moisture content in the desorption component promotes, and the ability of desorption moisture declines, for guaranteeing that equipment has continuous dehumidification ability, needs control desorption fan and heating element work to carry out effective desorption to the moisture in the desorption component to with the wet air water conservancy diversion to in the condenser, the condenser will gaseous state water condense into liquid water, reduces the moisture content of desorption component through above-mentioned process. The humidifier is the same, and desorption fan and heating element work need to be controlled in the humidification process, and the moisture in the desorption element is desorbed out to the air that will contain moisture is discharged indoor, realizes the humidification.

However, in the related art, referring to fig. 7, in a humidification process (or a desorption process during dehumidification), a fan operates to guide indoor dry and cold air into a pipeline, the temperature of the air rises after passing through a heating element, and the temperature approaches to the desorption temperature of a desorption element, so that moisture in the desorption element is effectively desorbed, and humidification is realized. The heating element needs to work with higher power to ensure that the temperature of the air flow reaching the desorption element is close to the desorption temperature, and the power required by the equipment to complete the humidification process (or the desorption process during dehumidification) is too high, so that the equipment cannot be used in some occasions with limited power, such as dormitories, and the application of the product is limited. Moreover, the heating element always works at higher power, so that the heating element is easy to break down, and the high temperature generated during the working of the heating element can also influence other parts in the equipment, so that the service life of the equipment is shorter.

The disclosed embodiments provide a desorption assembly comprising a first fan 1, a first conduit 2, a desorption element 3, a phase change element 4, and a heating element 5.

Wherein, the first fan 1 is connected with one end of the first pipeline 2; the other end of the first pipeline 2 is arranged opposite to the desorption element 3, the phase change element 4 is positioned on the first air path 100 between the first fan 1 and the desorption element 3, and the heating element 5 is positioned between the first fan 1 and the phase change element 4 and is connected with the first pipeline 2.

In this way, the phase change element 4 is arranged between the desorption element 3 and the heating element 5, the distance between the phase change element 4 and the heating element 5 is relatively short, the heating element 5 can be controlled to work first, the phase change element 4 receives heat to generate endothermic phase change, then the first fan 1 can be controlled to work, the power of the heating element 5 is reduced, so that air flows through the heating element 5, the phase change element 4 and the desorption element 3 in sequence, at the moment, the temperature of the air flow reaching the phase change element 4 is smaller than the phase change temperature of the phase change element 4, the phase change element 4 generates exothermic phase change, rapidly releases a great amount of heat to enable the temperature of the air flow reaching the desorption element 3 to be close to the desorption temperature, the moisture in the desorption element 3 is effectively desorbed, the heating element 5 only needs to operate with relatively low power in the whole process, the power required by the device to complete the humidification process (or the desorption process during dehumidification) is relatively small, the device can be used in a specific scene such as a scene of limiting the running power of the device, and the application scene of the device is widened.

Meanwhile, the working power of the heating element is low, faults are not easy to occur, the temperature generated during working of the heating element is low, the influence on other parts in the equipment is small, and the service life of the equipment can be prolonged.

The following describes the respective parts of the desorption assembly:

1. First fan 1

The first fan 1 is the component of the desorption assembly for introducing air into the first conduit 2.

As shown in fig. 1, an air outlet of the first fan 1 is communicated with one end of the first pipeline 2.

The first fan 1 may be a centrifugal fan or a She Shi fan, and the embodiment of the present disclosure is not limited to the type of the first fan 1.

The connection mode between the first fan 1 and the first pipeline 2 may be welding or clamping, and the connection mode between the first fan 1 and the first pipeline 2 is not limited in the embodiment of the disclosure.

Alternatively, the first fan 1 may be a high temperature resistant fan.

In the implementation, the rear end of the first fan 1 is provided with the heating element 5, so that the service life of the first fan 1 is prolonged, a metal fan can be selected for use, the heat resistance of the first fan 1 is improved, the first fan 1 is prevented from being deformed by heat to fail, the air outlet of the first fan 1 on the wall is deformed, the air tightness between the air outlet and the first pipeline 2 is caused, and the noise problem is caused.

2. First pipe 2

The first duct 2 is a component of the desorption assembly for forming a stable wind path.

As shown in fig. 1, one end of the first pipe 2 is communicated with an air outlet of the first fan 1, and the other end of the first pipe 2 is arranged opposite to the desorption element 3.

In the implementation, the first fan 1 works to guide indoor air into the desorption assembly, one end of the first pipeline 2 is communicated with the air outlet of the first fan 1, the other end of the first pipeline is oppositely arranged with the desorption element 3, a stable air path can be formed between the air outlet of the first fan 1 and the desorption element 3, random flow of air after the air flows out of the air outlet of the first fan 1 is avoided, and noise can be reduced.

Further, as shown in fig. 1, the first air path 100 is formed between the air outlet of the first fan 1 and the desorption element 3 through the first pipeline 2, so that the diffusion diameter of the air flow in the process of flowing through the desorption element 3 can be reduced, the flow speed of the air flow passing through the desorption element 3 can be improved, and further the desorption efficiency can be improved.

In one example, the first conduit 2 may be a circular conduit.

In this way, the flow field is stable when the air flow passes through the first pipeline 2, and noise can be reduced.

The first pipe 2 may be made of various high temperature resistant metal materials, such as alloy steel, special steel, etc., or high temperature resistant organic polymer materials, such as high temperature nylon, and the material of the first pipe 2 is not limited in this disclosure.

In some possible embodiments, the inner wall of the first conduit 2 has a receiving groove 21.

As shown in fig. 5, the inner wall of the first pipe 2 has a receiving groove 21.

In one example, the receiving groove 21 has a circular ring-shaped structure for receiving the heating element 5.

In practice, the heating element 5 is located in the accommodating groove 21 and is connected with the wall surface of the accommodating groove 21, and the connection manner between the heating element 5 and the accommodating groove 21 can be a clamping connection.

Alternatively, the heating element 5 may also have a circular ring-like structure, the inner diameter of the heating element 5 being equal to the inner diameter of the first pipe 2, and the outer diameter of the heating element 5 being equal to the groove bottom diameter of the receiving groove 21.

In this way, after the heating element 5 is mounted to the receiving groove 21, the inner wall of the heating element 5 can be made flush with the inner wall of the first duct 2. The air flow is not blocked when passing through the heating element 5, so that the stability of the air flow field in the first pipeline 2 can be improved, and the noise is reduced.

3. Desorption element 3

The desorption element 3 is a component of the desorption assembly for adsorbing moisture.

The desorption element 3 has a porous structure, specifically, the desorption element 3 may be made of a silica gel material, a molecular sieve material, or MOFs (Metal-Organic Frameworks, metal organic frameworks), and the material of the desorption element 3 is not limited in this embodiment.

In some possible embodiments, the desorption element 3 is made of MOFs.

The desorption element 3 made of MOFs has the advantages of high water absorption and low desorption temperature, and the heating element 5 works at lower power, so that the temperature of the air flow reaching the desorption element 3 is close to the desorption temperature, and the desorption element has obvious advantages in terms of energy consumption. However, the desorption element 3 made of MOFs can withstand a lower limit temperature, and when the temperature of the gas flow reaching the desorption element 3 is too high, the desorption element 3 made of MOFs is easily damaged, and even a fire risk occurs.

The desorption temperature of the desorption element 3 manufactured by MOFs is 120-130 ℃, and the phase change element 4 with the phase change temperature between 120-130 ℃ can be selected, so that the temperature of the air flow reaching the desorption element 3 can be controlled, and the desorption element 3 is prevented from being damaged.

In implementation, as shown in fig. 1, the heating element 5 works, when the air flow flowing through the heating element 5 is heated, and when the air flow reaches the phase change element 4, if the temperature of the air flow is higher than the phase change temperature of the phase change element 4, the phase change element 4 absorbs heat and phase change, absorbs heat in the air flow, reduces the temperature of the air flow reaching the desorption element 3, and enables the temperature of the air flow reaching the desorption element 3 to be between 120 and 130 ℃, so that the desorption efficiency is improved.

Illustratively, the phase change element 4 comprises one of sodium lauryl sulfate, stearic acid, and polyethylene glycol.

In some possible embodiments, the desorption element 3 is made of silica gel or molecular sieve.

The desorption element 3 made of silica gel or molecular sieve has the advantage of stronger thermal stability, and when the temperature of the air flow flowing through the desorption element 3 made of silica gel or molecular sieve is higher, the desorption element 3 is not easy to damage. But the desorption temperature of the desorption element 3 made of silica gel or molecular sieve is higher, and the heating element 5 needs to work with higher power, so that the air flow temperature reaching the desorption element 3 is close to the desorption temperature, the working power of the heating element 5 is higher, the application scene of the equipment is limited, and the service life of the equipment is shorter.

The desorption temperature of the desorption element 3 made of silica gel or molecular sieve is about 400 ℃, the phase change element 4 with the phase change temperature lower than 400 ℃ can be selected, and the phase change characteristic of the phase change element 4 is utilized, so that when the heating element 5 works with lower power, the temperature of the air flow reaching the desorption element 3 is remembered to be close to the desorption temperature, the application scene of the equipment is widened, and the service life of the equipment is prolonged.

In implementation, as shown in fig. 1, the phase change element 4 is disposed between the desorption element 3 and the heating element 5, where the distance between the phase change element 4 and the heating element 5 is relatively short, the heating element 5 can be controlled to operate first, the phase change element 4 receives heat to perform endothermic phase change, then the first fan 1 can be controlled to operate, and the power of the heating element 5 is reduced, so that air flows through the heating element 5, the phase change element 4 and the desorption element 3 in sequence, at this time, since the temperature of the air flow reaching the phase change element 4 is smaller than the phase change temperature of the phase change element 4, the phase change element 4 performs exothermic phase change, rapidly releases a great amount of heat to make the temperature of the air flow reaching the desorption element 3 approach the desorption temperature, so that moisture in the desorption element 3 is effectively desorbed, and the heating element 5 only needs to operate with relatively low power in the whole process to enable the phase change element 4 to achieve that the temperature of the air flow reaching the desorption element 3 approaches the desorption temperature, thereby widening the application range of the device. Meanwhile, the working power of the heating element is low, faults are not easy to occur, and the service life of the equipment can be prolonged.

Illustratively, the phase change element 4 comprises a high lead glass.

The phase change element 4 includes one of sodium dodecyl sulfate, stearic acid and polyethylene glycol, and the phase change element 4 includes high lead glass, which means that at least part of the constituent components of the phase change element 4 is made of one of sodium dodecyl sulfate, stearic acid or polyethylene glycol, or made of high lead glass, and the specific structure of the phase change element 4 will be described in detail below.

4. Phase change element 4

The phase change element 4 is the component in the desorption assembly that is used to adjust the temperature of the gas stream by phase change.

As shown in fig. 1, the phase change element 4 is located on the first air path 100 between the first fan 1 and the desorption element 3.

In implementation, since the phase change element 4 is a non-electric control component, the distance between the phase change element 4 and the desorption element 3 can be set to be shorter, so that the efficiency of adjusting the temperature of the air flow through phase change of the phase change element 4 is improved.

In one example, the phase change element 4 is located on a side of the desorption element 3 adjacent to the first conduit 2 and is in contact with the desorption element 3.

In one example, the phase change element 4 is located within the first conduit 2 and is connected to the first conduit 2.

In this way, the difficulty of assembling the phase change element 4 can be reduced.

Alternatively, the phase change element 4 may be welded to the first pipe 2.

In this way, the stability of the connection between the phase change element 4 and the first conduit 2 can be improved.

In some possible embodiments, referring to FIG. 2, the phase change element 4 has a mesh structure.

In this way, the contact area between the air flow flowing through the phase change element 4 and the phase change element 4 can be increased, and the efficiency of adjusting the air flow temperature by the phase change element 4 through phase change can be improved.

Illustratively, referring to FIG. 5, the outer ring of the phase change element 4 may have a circular structure with a rectangular mesh shape in the mesh structure.

In this way, the difficulty of processing the phase change element 4 can be reduced.

In some possible embodiments, phase change element 4 includes a frame 41, a phase change layer 42, and a protective layer 43.

As shown in fig. 3, the phase change element 4 includes a frame 41, a phase change layer 42, and a protective layer 43.

The frame 41 has a mesh structure. The phase change layer 42 is located at the outer ring of the frame 41 and is connected with the frame 41. The protection layer 43 is located at the outer periphery of the phase-change layer 42 and is connected to the phase-change layer 42.

In one example, the frame 41 includes a ring body and a plurality of connection beams (both shown), and the shape of the ring body may be matched with the shape of the inner ring of the first pipe 2, that is, in the case where the shape of the inner ring of the first pipe 2 is circular, the shape of the ring body is circular, and in the case where the shape of the inner ring of the first pipe 2 is rectangular, the shape of the ring body is rectangular. The connecting beams are distributed in the ring body in a staggered manner and are connected with the ring body.

Optionally, in the phase change element 4, the material of the frame body 41 is one of polyester fiber and polypropylene fiber.

In this way, the overall strength of the phase change element 4 can be improved.

Optionally, in the phase change element 4, the material of the phase change layer 42 is one of sodium dodecyl sulfate, stearic acid and polyethylene glycol.

Thus, the phase transition temperature of the phase transition layer 42 is between 120 ℃ and 130 ℃, the phase transition temperature of the phase transition layer 42 is lower, and when the desorption element 3 is made of MOFs, the temperature of the air flow flowing through the phase transition element 4 can be effectively controlled, the desorption element 3 is prevented from being damaged, and the efficiency of adjusting the air flow temperature through phase transition of the phase transition element 4 is improved. Under the condition that the desorption element 3 is made of silica gel or molecular sieve materials, the phase change element 4 can be driven to achieve that the temperature of the air flow reaching the desorption element 3 is close to the desorption temperature by phase change only by operating the heating element 5 with lower power, and the application scene of the device is widened. Meanwhile, the working power of the heating element is low, faults are not easy to occur, and the service life of the equipment can be prolonged.

Optionally, in the phase change element 4, the protective layer 43 is one of a polyester film and a polypropylene film.

5. Heating element 5

The heating element 5 is the component of the desorption assembly that heats the flow of gas.

As shown in fig. 1, a heating element 5 is located between the first fan 1 and the phase change element 4 and is connected to the first conduit 2.

In one example, as shown in fig. 4, the heating element 5 is located on the outer circumference of the first pipe 2 and is connected to the first pipe 2.

In this way, the difficulty of connection between the heating element 5 and the first conduit 2 can be reduced.

The heating element 5 may be an electrical resistance wire heating element, for example.

In this way, the cost of arrangement of the heating element 5 and thus the overall cost of the desorption assembly can be reduced.

The embodiment of the present disclosure provides an indoor air humidity conditioning apparatus, as shown in fig. 6, which includes the desorption assembly, the housing 6, the second fan 7, and the second duct 8 described above.

Wherein, casing 6 has first air intake 61 and second air intake 62, and first fan 1 is located first air intake 61, and links to each other with casing 6, and desorption element 3 is located the casing, and links to each other with casing 6, and second fan 7 is located second air intake 62, and links to each other with casing 6, and second fan 7 is linked together with the one end of second pipeline 8, and the field section of second pipeline 8 is arranged with desorption element 3 relatively.

Thus, in the indoor air humidity adjusting apparatus, a first air path 100 passing through the desorption element 3 may be formed by the second fan 7 and the second duct 8 to dehumidify the indoor air, and a second air path 200 passing through the desorption element 3 may be formed by the first fan 1, the first duct 2, the heating element 5 and the phase change element 4, in which the temperature of the air flow reaching the desorption element 3 approaches the desorption temperature of the desorption element 3, the moisture in the desorption element 3 may be effectively desorbed, so that the apparatus has a continuous dehumidification capability, and the second air path 200 may also be used to humidify the indoor air, and the indoor air humidity adjusting apparatus may integrate a dehumidification function and a humidification function.

In one example, the housing 6 also has a first air outlet 63 and a second air outlet 64.

Alternatively, the first air outlet 63 is disposed opposite the other end of the first duct 2, and the second air outlet 64 is disposed opposite the other end of the second duct 8.

In this way, the air flow can be prevented from forming back flow in the equipment, and noise can be reduced.

In one example, the desorption element 3 has a cylindrical structure and is rotatably connected to the housing 6.

As shown in fig. 6, the desorption element 3 is rotatably connected to the housing 6 through a rotation shaft, the other end of the first pipe 2 is disposed opposite to the first region of the desorption element 3, and the other end of the second pipe 8 is disposed opposite to the second region of the desorption element 3.

Alternatively, the axis of the shaft may coincide with the axis of the cylindrical structure.

In this way, stability of the desorbing element 3 in rotation relative to the housing 6 can be improved.

In implementation, the rotating shaft may be electrically connected to the controller, and the controller controls the rotating shaft to rotate at a constant angular velocity, so as to drive the desorption element 3 to rotate at a constant angular velocity.

Thus, the adsorption capacity of the desorption element 3 to moisture can be improved during dehumidification, and the humidification efficiency can be improved during humidification.
