Description

Technical Field

[0001] The present disclosure relates to the technical field of electrical appliances, and particularly relates to a desorption component and an indoor air humidity adjustment device. Background Art

[0002] Indoor air humidity adjustment devices include dehumidifiers, humidifiers, or humidity controllers integrating dehumidification / humidification functions. The desorption component is a core component in an indoor air humidity adjustment device. The desorption component includes a desorption fan, a heating element, and a desorption element, and the heating element is located between the desorption fan and the desorption element.

[0003] During the humidification process, liquid water is evenly distributed in the desorption element. The desorption fan operates to make the air flow towards the desorption element, and the heating element operates to increase the temperature of the air flow, so that the temperature of the air flow is close to the desorption temperature corresponding to the desorption element, effectively desorbing the liquid water in the desorption element, and then discharging the moisture-rich wet air into the room to achieve humidification. During the dehumidification process, the indoor wet air passes through the desorption element under the action of the dehumidification fan, and the moisture is adsorbed by the desorption element, and the dry air is discharged into the room. At the same time, the water content in the desorption element increases. The desorption fan and the heating element operate to effectively desorb the moisture in the desorption element and divert the wet air to the condenser. The condenser condenses the gaseous water into liquid water, and the water content of the desorption element is reduced through the above process to ensure that the device has continuous dehumidification ability.

[0004] However, in the above structure, whether it is the humidification process or the dehumidification process, when the device is working, the working power of the heating element is relatively high, and the application scenarios are limited. Summary of the Invention

[0031] The embodiments of the present disclosure provide a desorption assembly. In this desorption assembly, a fan is connected to one end of a first pipeline; the other end of the first pipeline is arranged opposite to the desorption element.

Subsequently, the first fan can be controlled to work, and the power of the heating element can be reduced, so that air flows through the heating element, the phase change element, and the desorption element in sequence. At this time, since the temperature of the air flow reaching the phase change element is lower than the phase change temperature of the phase change element, the phase change element undergoes an exothermic phase change and rapidly releases a large amount of heat, so that the temperature of the air flow reaching the desorption element is close to the desorption temperature, effectively desorbing the moisture in the desorption element. In the whole process, the heating element only needs to operate at a relatively low power to enable the phase change element to achieve that the temperature of the air flow reaching the desorption element is close to the desorption temperature through phase change.

[0054] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0056] During a specific season, the air humidity indoors may be too low or too high, resulting in a reduced level of comfort for users when living. This problem can be solved by installing an air humidity adjustment device indoors to adjust the air humidity. The indoor air humidity adjustment device can be a dehumidifier, a humidifier, or a humidity controller that integrates dehumidification / humidification functions. Among the indoor air humidity adjustment devices, the desorption component is the most core part. Taking a dehumidifier as an example, during the dehumidification process, the dehumidifying fan operates, and the air with a relatively high humidity indoors enters the device and flows through the desorption element. After the water molecules in the air come into contact with the desorption element, they are adsorbed by the desorption element, the content of water molecules in the air decreases, and the relatively dry air is discharged into the room, achieving the reduction of the indoor air humidity. At the same time, as more and more water is desorbed from the desorption element, the water content in the desorption element increases, and the ability to desorb water decreases. To ensure that the device has continuous dehumidification ability, it is necessary to control the operation of the desorption fan and the heating element to effectively desorb the water in the desorption element and divert the wet air to the condenser. The condenser condenses the gaseous water into liquid water, and the water content of the desorption element is reduced through the above process. The same principle applies to a humidifier. During the humidification process, it is necessary to control the operation of the desorption fan and the heating element to desorb the water in the desorption element and discharge the air containing water into the room to achieve humidification.

[0057] However, in the related art, referring to Figure 7, during the humidification process (or the desorption process during dehumidification), the blower operates to divert the dry and cold indoor air into the pipeline. After passing through the heating element, the temperature of the air rises and approaches the desorption temperature of the desorption element, effectively desorbing the moisture in the desorption element to achieve humidification. The heating element needs to operate at a relatively high power to ensure that the temperature of the air flow reaching the desorption element is close to the desorption temperature. If the power required for the device to complete the humidification process (or the desorption process during dehumidification) is too large, the device cannot be used in some scenarios with power limitations, such as in dormitories, and the application scenarios of the product are limited. Moreover, since the heating element always operates at a high power, not only is it prone to failure itself, but the high temperature generated during its operation will also affect other components in the device, resulting in a short service life of the device.

[0058] The embodiment of the present disclosure provides a desorption assembly, which includes a first blower 1, a first pipeline 2, a desorption element 3, a phase change element 4, and a heating element 5.

[0059] Among them, the first blower 1 is connected to 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 located on the first air path 100 between the first blower 1 and the desorption element 3, and the heating element 5 is located between the first blower 1 and the phase change element 4 and is connected to the first pipeline 2.

[0060] In this way, the phase change element 4 is arranged between the desorption element 3 and the heating element 5, and the distance between the phase change element 4 and the heating element 5 is relatively close. First, the heating element 5 can be controlled to operate, and the phase change element 4 absorbs heat and undergoes an endothermic phase change upon receiving the heat. Subsequently, the first blower 1 can be controlled to operate, and the power of the heating element 5 can be reduced, so that the 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 lower than the phase change temperature of the phase change element 4, the phase change element 4 undergoes an exothermic phase change and rapidly releases a large amount of heat, making the temperature of the air flow reaching the desorption element 3 close to the desorption temperature, effectively desorbing the moisture in the desorption element 3. During the whole process, the heating element 5 only needs to operate at a relatively low power to enable the phase change element 4 to achieve the temperature of the air flow reaching the desorption element 3 close to the desorption temperature through phase change. The power required for the device to complete the humidification process (or the desorption process during dehumidification) is small, and it can also be used in specific scenarios such as scenarios with power limitations for device operation, broadening the application scenarios of the device.

[0061] At the same time, since the operating power of the heating element is low, not only is it not prone to failure itself, but the temperature generated during its operation is also low, having less impact on other components in the device, and thus the service life of the device can be improved.

[0062] Next, each part of the desorption assembly will be introduced separately:

[0063] 1. The first blower 1

[0064] The first fan 1 is a component in the desorption assembly used to introduce air into the first pipe 2.

[0065] If Figure 1 As shown in , the air outlet of the first fan 1 is connected to one end of the first pipe 2.

[0066] The first fan 1 can be a centrifugal fan or a Ye blower. The embodiment of the present disclosure does not limit the type of the first fan 1.

[0067] The connection between the first fan 1 and the first pipeline 2 can be welding or clamping. The embodiment of the present disclosure does not limit the connection between the first fan 1 and the first pipeline 2.

[0068] Optionally, the first fan 1 may be a high temperature resistant fan.

[0069] In implementation, a heating element 5 is provided at the rear end of the first fan 1. In order to increase the service life of the first fan 1, a metal fan can be selected to improve the heat resistance of the first fan 1, to avoid the first fan 1 being deformed by heat and causing failure, and to prevent the air outlet of the first fan 1 from deforming, resulting in problems with the air tightness between the air outlet and the first pipe 2, and noise problems.

[0070] 2. First Pipeline 2

[0071] The first pipe 2 is a component used to form a stable air path in the desorption component.

[0072] If Figure 1 As described above, one end of the first pipe 2 is connected to the air outlet of the first fan 1, and the other end of the first pipe 2 is arranged opposite to the desorption element 3.

[0073] In implementation, the first fan 1 works to guide the indoor air to the desorption component. One end of the first pipe 2 is connected to the air outlet of the first fan 1, and the other end is arranged opposite to the desorption element 3, so that a stable air path can be formed between the air outlet of the first fan 1 and the desorption element 3, so as to prevent the air from dispersing arbitrarily after flowing out of the air outlet of the first fan 1, thereby reducing noise.

[0074] Furthermore, if Figure 1 As shown in FIG. 1 , a first air path 100 is formed between the air outlet of the first fan 1 and the desorption element 3 through the first pipe 2, which can reduce the diffusion diameter of the airflow when the airflow passes through the desorption element 3, increase the flow rate of the airflow passing through the desorption element 3, and thus improve the desorption efficiency.

[0075] In one example, the first pipe 2 may be a circular pipe.

[0076] ​​In this way, the flow field of the air flow is relatively stable when passing through the first duct 2, and the noise can be reduced.

[0077] The first duct 2 can be made of various high-temperature-resistant metal materials, such as alloy steel, special steel, etc., or can be made of high-temperature-resistant organic polymer materials, such as high-temperature nylon. The present disclosure does not limit the material of the first duct 2.

[0078] In some possible embodiments, the inner wall of the first duct 2 has a receiving groove 21.

[0079] As Figure 5 shown, the inner wall of the first duct 2 has a receiving groove 21.

[0080] In one example, the receiving groove 21 has an annular structure for receiving the heating element 5.

[0081] In implementation, the heating element 5 is located in the receiving groove 21 and is connected to the wall surface of the receiving groove 21. The connection manner between the heating element 5 and the receiving groove 21 can be snap connection.

[0082] Optionally, the heating element 5 can also have an annular structure. The inner diameter of the heating element 5 is equal to the inner diameter of the first duct 2, and the outer diameter of the heating element 5 is equal to the bottom diameter of the receiving groove 21.

[0083] In this way, after the heating element 5 is installed in the receiving groove 21, the inner wall of the heating element 5 can be flush with the inner wall of the first duct 2. When the air flow passes through the heating element 5, it will not be blocked, which can improve the stability of the gas flow field in the first duct 2 and reduce the noise.

[0084] III. Desorption element 3

[0085] The desorption element 3 is a component in the desorption assembly for adsorbing moisture.

[0086] The desorption element 3 has a porous structure. Specifically, the desorption element 3 can be made of silica gel material, or can be made of molecular sieve material, or can also be made of MOFs (Metal-Organic Frameworks). The present disclosure does not limit the material of the desorption element 3 in the embodiments.

[0087] In some possible embodiments, the material of the desorption element 3 is MOFs.

[0088] The desorption element 3 made of MOFs has the advantages of high water absorption capacity and low desorption temperature. The heating element 5 can operate at a relatively low power to make the temperature of the air flow reaching the desorption element 3 close to the desorption temperature, which has obvious advantages in terms of energy consumption. However, the desorption element 3 made of MOFs can withstand a relatively low limit temperature. When the temperature of the air flow reaching the desorption element 3 is too high, the desorption element 3 made of MOFs is likely to be damaged, and there is even a risk of fire.

[0089] The desorption temperature of the desorption element 3 made of MOFs is between 120 and 130 °C. A phase change element 4 with a phase change temperature between 120 and 130 °C can be selected to control the temperature of the air flow reaching the desorption element 3 and avoid damage to the desorption element 3.

[0090] In implementation, as Figure 1 shown, the heating element 5 operates to increase the temperature of the air flow passing through the heating element 5. 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 undergoes an endothermic phase change, absorbing the heat in the air flow and reducing the temperature of the air flow reaching the desorption element 3, so that the temperature of the air flow reaching the desorption element 3 is between 120 and 130 °C, thereby improving the desorption efficiency.

[0091] Exemplarily, the phase change element 4 includes one of sodium dodecyl sulfate, stearic acid, and polyethylene glycol.

[0092] In some possible embodiments, the material of the desorption element 3 is silica gel or molecular sieve.

[0093] The desorption element 3 made of silica gel or molecular sieve has the advantage of strong thermal stability. When the temperature of the air flow passing through the desorption element 3 made of silica gel or molecular sieve is relatively high, the desorption element 3 is not easily damaged. However, the desorption temperature of the desorption element 3 made of silica gel or molecular sieve is relatively high, and the heating element 5 needs to operate at a relatively high power to make the temperature of the air flow reaching the desorption element 3 close to the desorption temperature. The working power of the heating element 5 is relatively high, the application scenario of the equipment is limited, and moreover, the service life of the equipment is relatively short.

[0094] The desorption temperature of the desorption element 3 made of silica gel or molecular sieve is about 400 °C. A phase change element 4 with a phase change temperature below 400 °C can be selected. By utilizing the phase change characteristics of the phase change element 4, when the heating element 5 operates at a relatively low power, it can be ensured that the temperature of the air flow reaching the desorption element 3 is close to the desorption temperature, thereby broadening the application scenario of the equipment and improving the service life of the equipment at the same time.

[0095] In implementation, as Figure 1As shown, the phase change element 4 is disposed 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 close. First, the heating element 5 can be controlled to operate. The phase change element 4 absorbs heat and undergoes an endothermic phase change upon receiving the heat. Subsequently, the first fan 1 can be controlled to operate, and the power of the heating element 5 can be reduced, such that air sequentially flows through the heating element 5, the phase change element 4, and the desorption element 3. At this time, since the temperature of the air flow reaching the phase change element 4 is lower than the phase change temperature of the phase change element 4, the phase change element 4 undergoes an exothermic phase change and rapidly releases a large amount of heat, so that the temperature of the air flow reaching the desorption element 3 approaches the desorption temperature, effectively desorbing the moisture in the desorption element 3. During the whole process, the heating element 5 only needs to operate at a relatively low power to enable the phase change element 4 to achieve, through phase change, that the temperature of the air flow reaching the desorption element 3 approaches the desorption temperature, broadening the application scenarios of the device. Meanwhile, the working power of the heating element is relatively low, and faults are not likely to occur, thereby improving the service life of the device.

[0096] Exemplarily, the phase change element 4 comprises high-lead glass.

[0097] In the above text, the phase change element 4 comprises one of sodium dodecyl sulfate, stearic acid, and polyethylene glycol, and the phase change element 4 comprises high-lead glass, which means that at least part of the components of the phase change element 4 are made of one of sodium dodecyl sulfate, stearic acid, or polyethylene glycol, or are made of high-lead glass. The specific structure of the phase change element 4 will be introduced in detail below.

[0098] IV. Phase Change Element 4

[0099] The phase change element 4 is a component in the desorption assembly for adjusting the air flow temperature through phase change.

[0100] As Figure 1 shown, the phase change element 4 is located on the first air path 100 between the first fan 1 and the desorption element 3.

[0101] In implementation, since the phase change element 4 is a non-electrically controlled component, the distance between the phase change element 4 and the desorption element 3 can be set to be relatively short, thereby improving the efficiency of the phase change element 4 in adjusting the air flow temperature through phase change.

[0102] In one example, the phase change element 4 is located on the side of the desorption element 3 close to the first pipe 2 and is in contact with the desorption element 3.

[0103] In one example, the phase change element 4 is located inside the first pipe 2 and is connected to the first pipe 2.

[0104] In this way, the assembly difficulty of the phase change element 4 can be reduced.

[0105] Optionally, the connection manner between the phase change element 4 and the first pipe 2 can be welding.

[0106] In this way, the connection stability between the phase change element 4 and the first pipe 2 can be improved.

[0107] In some possible embodiments, referring to Figure 2 , the phase change element 4 has a mesh structure.

[0108] In this way, the contact area between the air flow passing through the phase change element 4 and the phase change element 4 can be increased. Furthermore, the efficiency of the phase change element 4 to adjust the air flow temperature through phase change can be improved.

[0109] Exemplarily, referring to Figure 5 , the outer ring of the phase change element 4 may have a circular structure, and the shape of the mesh holes in the mesh structure is rectangular.

[0110] In this way, the processing difficulty of the phase change element 4 can be reduced.

[0111] In some possible embodiments, the phase change element 4 includes a frame body 41, a phase change layer 42, and a protective layer 43.

[0112] As Figure 3 shown, the phase change element 4 includes a frame body 41, a phase change layer 42, and a protective layer 43.

[0113] Among them, the frame body 41 has a mesh structure. The phase change layer 42 is located on the outer ring of the frame body 41 and is connected to the frame body 41. The protective layer 43 is located on the outer ring of the phase change layer 42 and is connected to the phase change layer 42.

[0114] In one example, the frame body 41 includes a ring body and a plurality of connecting beams (not shown). The shape of the ring body can match the shape of the inner ring of the first pipe 2. That is, when the inner ring shape of the first pipe 2 is circular, the shape of the ring body is circular; when the inner ring shape of the first pipe 2 is rectangular, the shape of the ring body is rectangular. The plurality of connecting beams are staggered and distributed in the ring body and are connected to the ring body.

[0115] Optionally, in the phase change element 4, the material of the frame body 41 is one of polyester fiber and polypropylene fiber.

[0116] In this way, the overall strength of the phase change element 4 can be improved.

[0117] 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.

[0118] In this way, the phase change temperature of the phase change layer 42 is between 120 and 130 °C. The phase change temperature of the phase change layer 42 is relatively low. When the desorption element 3 is made of MOFs, it can effectively control the temperature of the air flow passing through the phase change element 4, prevent the desorption element 3 from being damaged, and improve the efficiency of the phase change element 4 to adjust the air flow temperature through phase change. When the desorption element 3 is made of silica gel or molecular sieve material, only the heating element 5 needs to operate at a low power to enable the phase change element 4 to achieve the temperature of the air flow reaching the desorption element 3 close to the desorption temperature through phase change, broadening the application scenario of the device. At the same time, the working power of the heating element is low and it is not easy to fail, thereby improving the service life of the device.

[0119] Optionally, in the phase change element 4, the protective layer 43 is one of a polyester film and a polypropylene film.

[0120] V. Heating element 5

[0121] The heating element 5 is a component in the desorption assembly that heats the air flow passing through.

[0122] As Figure 1 shown, the heating element 5 is located between the first fan 1 and the phase change element 4 and is connected to the first pipe 2.

[0123] In one example, as Figure 4 shown, the heating element 5 is located on the outer circle of the first pipe 2 and is connected to the first pipe 2.

[0124] In this way, the connection difficulty between the heating element 5 and the first pipe 2 can be reduced.

[0125] Exemplarily, the heating element 5 can be a resistance wire heating element.

[0126] In this way, the layout cost of the heating element 5 can be reduced, and thus the overall cost of the desorption assembly can be reduced.

[0127] The technical solutions provided by the embodiments of the present disclosure at least include the following beneficial effects:

[0128] The embodiments of the present disclosure provide a desorption assembly, which includes a first fan 1, a first pipe 2, a desorption element 3, a phase change element 4, and a heating element 5.

[0129] Among them, the first fan 1 is connected to one end of the first pipe 2; the other end of the first pipe 2 is arranged opposite to the desorption element 3, the phase change element 4 is located on the first air path 100 between the first fan 1 and the desorption element 3, and the heating element 5 is located between the first fan 1 and the phase change element 4 and is connected to the first pipe 2.

[0130] 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 close. First, the heating element 5 can be controlled to operate. The phase change element 4 absorbs heat and undergoes an endothermic phase change upon receiving heat. Subsequently, the first blower 1 can be controlled to operate, and the power of the heating element 5 can be 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 lower than the phase change temperature of the phase change element 4, the phase change element 4 undergoes an exothermic phase change and rapidly releases a large amount of heat, making the temperature of the air flow reaching the desorption element 3 close to the desorption temperature, effectively desorbing the moisture in the desorption element 3. During the entire process, the heating element 5 only needs to operate at a relatively low power to enable the phase change element 4 to achieve a temperature of the air flow reaching the desorption element 3 close to the desorption temperature through phase change. The power required for the device to complete the humidification process (or the desorption process during dehumidification) is relatively small, and it can also be used in specific scenarios such as scenarios where the operating power of the device is restricted, broadening the application scenarios of the device.

[0131] Meanwhile, the operating power of the heating element is relatively low. Not only is it not prone to failure itself, but the temperature generated during its operation is also relatively low, having less impact on other components in the device. Thus, the service life of the device can be improved.

[0132] The present disclosure provides an indoor air humidity adjustment device, such as Figure 6 shown. This indoor air humidity adjustment device includes the above-mentioned desorption assembly, a housing 6, a second blower 7, and a second duct 8.

[0133] Among them, the housing 6 has a first air inlet 61 and a second air inlet 62. The first blower 1 is located in the first air inlet 61 and is connected to the housing 6. The desorption element 3 is located inside the housing and is connected to the housing 6. The second blower 7 is located in the second air inlet 62 and is connected to the housing 6. The second blower 7 is connected to one end of the second duct 8, and the domain section of the second duct 8 is arranged opposite to the desorption element 3.

[0134] In this way, in the indoor air humidity adjustment device, through the second blower 7 and the second duct 8, a first air path 100 passing through the desorption element 3 can be formed to dehumidify the indoor air. Moreover, through the first blower 1, the first duct 2, the heating element 5, and the phase change element 4, a second air path 200 passing through the desorption element 3 can be formed. The temperature of the air flow reaching the desorption element 3 in this air path is close to the desorption temperature of the desorption element 3, which can effectively desorb the moisture in the desorption element 3, enabling the device to have continuous dehumidification ability. Moreover, the second air path 200 can also be used to humidify the indoor air, and the indoor air humidity adjustment device can integrate the dehumidification function and the humidification function.

[0135] In one example, the housing 6 also has a first air outlet 63 and a second air outlet 64.

[0136] Optionally, the first air outlet 63 is disposed opposite to the other end of the first duct 2, and the second air outlet 64 is disposed opposite to the other end of the second duct 8.

[0137] In this way, the formation of air flow reflux in the device can be avoided, and the noise can be reduced.

[0138] In one example, the desorption element 3 has a cylindrical structure and is rotatably connected to the housing 6.

[0139] As Figure 6 described, the desorption element 3 is rotatably connected to the housing 6 through a rotating shaft. The other end of the first duct 2 is disposed opposite to the first region of the desorption element 3, and the other end of the second duct 8 is disposed opposite to the second region of the desorption element 3.

[0140] Optionally, the axis of the rotating shaft may coincide with the axis of the cylindrical structure.

[0141] In this way, the stability of the desorption element 3 when rotating relative to the housing 6 can be improved.

[0142] 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, thereby driving the desorption element 3 to rotate at a constant angular velocity.

[0143] In this way, during dehumidification, the water adsorption capacity of the desorption element 3 can be improved, and during humidification, the humidification efficiency can be improved.

[0144] The embodiments of the present disclosure provide a processing method for a phase change element, and the method includes:

[0145] Step 801: Heat the phase change material to a liquid state, and coat the liquid phase change material on the organic molecular film to obtain a phase change layer and a protective layer.

[0146] Among them, the phase change material is one of sodium dodecyl sulfate, stearic acid, and polyethylene glycol, and the organic molecular film is one of polyester film and polypropylene film.

[0147] Step 802: Place the connecting beams staggered, and reinforce and connect the overlapping positions of the connecting beams to obtain a frame body;

[0148] Among them, the connecting beam has a strip structure, the material of the connecting beam can be one of polyester fiber and polypropylene fiber, the reinforcement connection can be laser welding, and the frame body has a mesh structure.

[0149] Step 803: Wrap the protective layer of the phase change layer on the frame body to obtain a phase change element.

[0150] Among them, in the phase change element, the protective layer is located on the outer circle of the phase change material.

[0151] In implementation, the movable phase change layer and the protective layer can be arranged such that the phase change layer is attached to the frame body. Subsequently, the protective layer is bent so that the phase change layer and the protective layer cover the outer circle of the frame body, obtaining a phase change element.

[0152] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included within the protection scope of the present disclosure.
