Description

Technical Field

[0001] The present application relates to but is not limited to the technical field of electrical equipment, and specifically refers to an air handling device and a control method. Background Art

[0002] According to the theory adopted by the Joint Atmospheric Commission of the International Union of Geodesy and Geophysics, healthy air negative ions mainly include O2 - (H2O)n、OH - (H2O)n、CO4 - (H2O)n, etc., are called "negative alkaline ions" or "hydrated negative ions". Hydrated negative ions have a half-life of 60s and a long life. In life, after a thunderstorm or beside a waterfall, people will feel the air is fresh, because there are a lot of "hydrated negative ions" in the air.

[0003] The related technology provides a hydrated air negative ion generator, including tourmaline, a pure water tank, a water volatilization device and a fan. The pure water tank is filled with pure water. The water volatilization device volatilizes the pure water in the pure water tank. The volatilized pure water passes through the tourmaline under the action of the fan. The tourmaline splits water molecules to generate hydrated negative ions. The hydrated negative ions enter the environment, thereby improving the environmental air quality.

[0004] The hydrated air negative ion generator has a low degree of automation. When the pure water tank is short of water, the user needs to add water manually, which is not very practical. Summary of the invention

[0040] In the present invention, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; "connection" can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] The air treatment equipment provided in the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, it includes: a generating module 100, the generating module 100 is configured to split water molecules to generate hydrated negative ions; a desiccant module 200, the desiccant module 200 is configured to absorb moisture; a fan module 300, the fan module 300 is configured to form a wind beam flowing from the desiccant module 200 to the generating module 100; and a water releasing module 400, the water releasing module 400 cooperates with the desiccant module 200, and the water releasing module 400 is configured to release the moisture adsorbed by the desiccant module 200.

[0043] Desiccant process: the fan module 300 is running, the water release module 400 is closed, and the ambient air passes through the desiccant module 200 and then blows toward the generating module 100 under the action of the fan module 300. When the ambient air passes through the desiccant module 200, the desiccant module 200 absorbs moisture in the air and stores it in the desiccant module 200;

[0044] Process of generating hydrated negative ions: the fan module 300 is running, and under the action of the fan module 300, the ambient air passes through the moisture absorption module 200 and then blows toward the generation module 100, and the water release module 400 is running, and the water release module 400 releases the moisture adsorbed by the moisture absorption module 200, and the released moisture passes through the generation module 100 with the wind beam, thereby increasing the probability of the moisture contacting the generation module 100, so that the generation module 100 decomposes water molecules to generate a large amount of hydrated negative ions, and the hydrated negative ions enter the environment with the wind beam, thereby improving the ambient air quality;

[0045] The air treatment equipment saves the user from the operation of manually adding water and does not increase the ambient humidity, so it is more practical.

[0046] In some examples, such as Figure 2 As shown, the air treatment equipment also includes: a humidity detection module, which is configured to detect the humidity of the air upstream of the desiccant module 200 and the humidity of the air downstream of the desiccant module 200; and a control module, the humidity detection module, the fan module 300 and the water release module 400 are all electrically connected to the control module.

[0047] During the moisture absorption process, when the air humidity difference between the upstream and downstream of the moisture absorption module 200 reaches a first set value, the control module controls the fan module 300 to turn off or execute the process of generating hydrated negative ions. The first set value may be set to no more than 3%, at which time the moisture absorbed by the moisture absorption module 200 is basically saturated, so turning off the fan module 300 by the control module can save energy consumption, and of course, the control module can also execute the process of generating hydrated negative ions to improve the ambient air quality.

[0048] In some embodiments, Figure 2As shown, the humidity detection module includes a first humidity sensor 510 and a second humidity sensor 520. The first humidity sensor 510 and the second humidity sensor 520 are respectively arranged upstream and downstream of the moisture absorption module 200, and the first humidity sensor 510 and the second humidity sensor 520 are both electrically connected to the control module. Specifically, the first humidity sensor 510 is arranged upstream of the dehumidification module 200, and the second humidity sensor 520 is arranged downstream of the dehumidification module 200; during the dehumidification process, the control module controls the operation of the fan module 300, and the ambient air forms a wind beam flowing from the dehumidification module 200 to the generation module 100 under the action of the fan module 300. The first humidity sensor 510 detects the air humidity of the wind beam upstream of the dehumidification module 200, and the second humidity sensor 520 detects the air humidity of the wind beam downstream of the dehumidification module 200. Since the dehumidification module 200 absorbs moisture in the wind beam during the process of the wind beam passing through the dehumidification module 200, the percentage of the air humidity of the wind beam detected by the first humidity sensor 510 upstream of the dehumidification module 200 is not less than the percentage of the air humidity of the wind beam detected by the second humidity sensor 520 downstream of the dehumidification module 200.

[0049] It may be that the components of the generation module 100 include tourmaline; or it may be that the components of the generation module 100 include negative ion powder, and the negative ion powder may be tourmaline powder, modified tourmaline powder, rare earth element powder, etc.; or it may be that the components of the generation module 100 include tourmaline and ion powder, etc.; it may be that the generation module 100 also includes a first carrier for loading tourmaline and / or negative ion powder, and the structure of the first carrier includes a honeycomb structure (the honeycomb structure has an air passage for the passage of an air beam); or it may be that the structure of the generation module 100 includes a particle filling structure (the particle filling structure has an air passage for the passage of an air beam); or it may be that the structure of the generation module 100 includes a honeycomb structure and a particle filling structure, etc.; all of the above can achieve the purpose of the present application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of the present application.

[0050] It may be that the components of the desiccant module 200 include molecular sieves; or it may be that the components of the desiccant module 200 include activated alumina; or it may be that the components of the desiccant module 200 include silica gel; or it may be that the components of the desiccant module 200 include molecular sieves and silica gel; or it may be that the components of the desiccant module 200 include molecular sieves and activated alumina; or it may be that the components of the desiccant module 200 include silica gel and activated alumina; or it may be that the components of the desiccant module 200 include molecular sieves, silica gel and activated alumina, etc.; it may be that the desiccant module 200 also includes a second carrier of molecular sieves, activated alumina and / or silica gel, and the structure of the second carrier includes a honeycomb structure (the honeycomb structure has an air passage for a wind beam to pass through); or it may be that the structure of the desiccant module 200 includes a particle filling structure (the particle filling structure has an air passage for a wind beam to pass through); or it may be that the structure of the desiccant module 200 includes a honeycomb structure and a particle filling structure, etc.; all of the above can achieve the purpose of the present application, and its purpose does not deviate from the design concept of the present invention, and will not be repeated here, and all should belong to the protection scope of the present application.

[0051] The generating module 100 and the moisture absorption module 200 may be integrated, and the generating module 100 and the moisture absorption module 200 may be the same module. For example, the powder components of the generating module 100 and the powder components of the moisture absorption module 200 may be mixed and loaded onto the same carrier to form.

[0052] The water release module 400 may include a heating module, or the heating module may include a thermistor or a thermocouple, etc.; or the water release module 400 may include an ultrasonic atomization module, etc.; all of the above can achieve the purpose of the present application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of the present application.

[0053] It may be that the water release module 400 includes a heating module, the heating module includes a thermistor, and the structure of the thermistor includes a honeycomb structure (the honeycomb structure has an air passage for the air beam to pass through). In the process of generating hydrated negative ions, the temperature of the air beam increases after passing through the honeycomb structure of the thermistor. The heated air beam passes through the desiccant module 200, which will reduce the adsorption performance of the adsorption module and increase the volatilization rate of the water adsorbed by the desiccant module 200, so that the water adsorbed by the desiccant module 200 is released.

[0054] In some embodiments, Figure 1 and Figure 2 As shown, the air treatment device further includes a temperature detection module 600, which is electrically connected to the control module and is disposed upstream of the moisture absorption module to more accurately control the temperature of the water release module 400. Alternatively, the temperature detection module 600 is configured as a temperature sensor.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the water release module 400 is located upstream of the moisture absorption module 200, and the fan module 300 is located downstream of the generation module 100. The fan module 300 forms a wind beam flowing from the moisture absorption module 200 to the generation module 100 in a negative pressure suction manner. In other embodiments, the water release module 400 is located upstream of the moisture absorption module 200, and the fan module 300 is located upstream of the water release module 400. The fan module 300 forms a wind beam flowing from the moisture absorption module 200 to the generation module 100 in a blowing manner.

[0056] In some embodiments, at least one of the generating module 100, the water releasing module 400 and the moisture absorbing module 200 has an air passage for the air beam to pass through. In some embodiments, the generating module 100, the water releasing module 400 and the moisture absorbing module 200 all have an air passage for the air beam to pass through.

[0057] In some embodiments, the air treatment device further comprises: a housing (not shown) having an air passage, wherein the generation module 100, the moisture absorption module 200, the fan module 300 and the water release module 400 are all arranged in the air passage. When the fan module 300 is in operation, the ambient air enters the air passage from the air inlet of the air passage, and then passes through the water release module 400, the moisture absorption module 200, the generation module 100 and the fan module 300 in sequence, and then is discharged back into the environment from the air outlet of the air passage.

[0058] By using the air treatment equipment provided in the present application, the process of generating hydrated negative ions can produce negative ions with a concentration of 5 million to 30 million per cubic centimeter, and these negative ions contain a large number of hydrated negative ions.

[0059] Among them, the moisture absorption module 200 and the generation module 100 can also be directly connected together, and the purpose of this application can also be achieved. Its purpose does not deviate from the design concept of the present invention and will not be repeated here. It should also fall within the protection scope of this application.

[0060] The control method of the air treatment equipment provided in the embodiment of the present invention includes:

[0061] Moisture absorption process: operate the fan module 300 and close the water release module 400;

[0062] Process of generating hydrated negative ions: operating the fan module 300 and operating the water release module 400.

[0063] Dehumidification process: the fan module 300 is operated, and the water release module 400 is closed. Under the action of the fan module 300, the ambient air passes through the dehumidification module 200 and then blows toward the generation module 100. When the ambient air passes through the dehumidification module 200, the dehumidification module 200 absorbs moisture in the air and stores it in the dehumidification module 200.

[0064] Process of generating hydrated negative ions: the fan module 300 is operated, and the ambient air passes through the moisture absorption module 200 and then blows toward the generation module 100 under the action of the fan module 300, and the water release module 400 is operated, and the water release module 400 releases the moisture adsorbed by the moisture absorption module 200, and the released moisture passes through the generation module 100 with the wind beam, thereby increasing the probability of the moisture contacting the generation module 100, so that the generation module 100 decomposes water molecules to generate a large amount of hydrated negative ions, and the hydrated negative ions enter the environment with the wind beam, thereby improving the ambient air quality;

[0065] This control method saves the user from having to manually add water, and does not increase the ambient humidity.

[0066] In some examples, during the moisture absorption process, the operating speed of the fan module 300 is a first set speed; during the generation of hydrated negative ions, the operating speed of the fan module 300 is a second set speed, and the second set speed is not greater than the first set speed. During the generation of hydrated negative ions, reducing the operating speed of the fan module 300 is conducive to more complete contact between the water released by the water release module 400 and the generation module 100, and prolonging the contact time between the water released by the water release module 400 and the generation module 100, so as to increase the generation of hydrated negative ions.

[0067] In some embodiments, Figure 3 As shown, the first set speed is the maximum operating speed A of the fan module 300, and the second set speed is not greater than 0.25*A. In the process of generating hydrated negative ions in this scheme, more hydrated negative ions can be generated, and the effect of improving the ambient air quality is better.

[0068] In some examples, the control method further includes: during the moisture absorption process, based on the running time of the fan module 300 reaching the first set time, turning off the fan module 300 or executing the process of generating hydrated negative ions. By reasonably setting the first set time, it is ensured that the moisture adsorbed by the moisture absorption module 200 reaches saturation or substantially saturation during the moisture absorption process, and then turning off the fan module 300 to save energy (or executing the process of generating hydrated negative ions to improve the ambient air quality).

[0069] In other examples, such as Figure 3As shown, the control method further includes: during the moisture absorption process, obtaining the air humidity of the wind beam upstream of the moisture absorption module 200 and downstream of the moisture absorption module 200, and based on the difference in air humidity upstream and downstream of the moisture absorption module 200 reaching a first set value, turning off the fan module 300 or executing a process of generating hydrated negative ions. It can be that the first set value is set to no more than 3%, at which time the moisture adsorbed by the moisture absorption module 200 is saturated or substantially saturated, so the fan module 300 is turned off to save energy (or the process of generating hydrated negative ions is executed to improve the ambient air quality).

[0070] The first setting value may be set to 3%; or the first setting value may be set to 2%; or the first setting value may be set to 1%, etc.; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the protection scope of this application.

[0071] In some examples, the water release module 400 includes a heating module, and the air treatment equipment also includes a temperature detection module 600, which is arranged upstream of the desiccant module. The control method also includes: in the process of generating hydrated negative ions, the temperature of the wind beam upstream of the desiccant module 200 is obtained, and according to the temperature of the wind beam upstream of the desiccant module 200, the heating module is controlled to blow a wind beam of a first set heating temperature to the desiccant module 200 for a second set time (that is, the temperature detected by the temperature detection module 600 is maintained at the first set heating temperature for a second set time), and then the heating module is turned off or the desiccant process is performed. During the process of generating hydrated negative ions, the heating module is controlled according to the temperature detected by the temperature detection module to blow a beam of wind with a first set heating temperature to the desiccant module 200 for a second set time period, so that the desiccant module 200 releases all or substantially all of the adsorbed moisture, and then the heating module is turned off to save energy. If the ambient air quality is no longer to be improved, the blowing component is turned off to save energy. If the ambient air quality is still to be improved, the desiccant process and the process of generating hydrated negative ions are performed in sequence.

[0072] In some embodiments, the first set heating temperature is set to 100° C. to 150° C., and the second set time can be determined based on experiments.

[0073] The first set heating temperature may be set to 100°C; or the first set heating temperature may be set to 125°C; or the first set heating temperature may be set to 150°C, etc.; all of the above can achieve the purpose of this application, and their purpose does not deviate from the design concept of the present invention, and will not be repeated here, and should all fall within the scope of protection of this application.

[0074] In other examples, such as Figure 3As shown, the water release module 400 includes a heating module, and the air treatment equipment also includes a temperature detection module 600, which is arranged upstream of the desiccant module 200. The control method also includes: in the process of generating hydrated negative ions, the temperature of the wind beam upstream of the desiccant module 200 is obtained, and according to the temperature of the wind beam upstream of the desiccant module 200, the heating module is controlled to blow the wind beam with the corresponding set heating temperature to the desiccant module 200 in stages, and then the heating module is turned off or the desiccant process is performed.

[0075] During the process of generating hydrated negative ions, the heating module is controlled according to the temperature detected by the temperature detection module 600, so as to blow air beams with corresponding set heating temperatures to the desiccant module 200 in stages, so as to regenerate the hydrated negative ions in stages (i.e. in stages). After the desiccant module 200 releases all or substantially all of the adsorbed moisture, the heating module is turned off to save energy. If the ambient air quality is no longer to be improved, the blowing component is turned off to save energy. If the ambient air quality is still to be improved, the desiccant process and the process of generating hydrated negative ions are performed in sequence.

[0076] In some examples, such as Figure 3 As shown, in any two adjacent stages, the temperature of the air beam blown to the desiccant module 200 in the latter stage is ≥ the temperature of the air beam blown to the desiccant module 200 in the former stage, that is, the temperature of the air beam blown to the desiccant module 200 increases step by step, so that in the process of generating hydrated negative ions, the release time of hydrated negative ions can be extended.

[0077] In some embodiments, Figure 3 As shown, wind beams with corresponding set heating temperatures are blown to the desiccant module 200 in four stages; in the first stage, wind beams at 40°C to 60°C are blown to the desiccant module 200, and the duration of the first stage is 2min to 20min; in the second stage, wind beams at 60°C to 80°C are blown to the desiccant module 200, and the duration of the second stage is 2min to 20min; in the third stage, wind beams at 80°C to 100°C are blown to the desiccant module 200, and the duration of the third stage is 2min to 20min; in the fourth stage, wind beams at not less than 100°C are blown to the desiccant module 200, and the duration of the fourth stage is 1min to 20min; in this scheme, hydrated negative ions are regenerated in stages during the process of generating hydrated negative ions, and the release time of hydrated negative ions is longer.

[0078] A control method for air handling equipment, such as Figure 3 As shown, including:

[0079] Hygroscopic process:

[0080] The fan module 300 runs at a rotation speed A, and the water release module 400 is closed;

[0081] Obtaining the air humidity B1 of the air beam upstream of the moisture absorption module 200 and the air humidity B2 downstream of the moisture absorption module 200;

[0082] Based on the fact that B1-B2 is not greater than 3%, the process of generating hydrated negative ions is performed;

[0083] The process of generating hydrated negative ions:

[0084] The fan module 300 operates at a speed of 0.25*A and the water release module 400 operates;

[0085] Obtain the temperature of the air beam upstream of the dehumidification module 200, and control the heating module according to the temperature of the air beam upstream of the dehumidification module 200, so as to successively blow a 40°C to 60°C air beam to the dehumidification module for 2 to 20 minutes, blow a 60°C to 80°C air beam to the dehumidification module for 2 to 20 minutes, blow a 80°C to 100°C air beam to the dehumidification module for 2 to 20 minutes, blow a temperature greater than 100°C air beam to the dehumidification module for 1 to 20 minutes, and then perform the dehumidification process.

[0086] In summary, the technical solution proposed in the embodiment of the present invention is as follows: the desiccant process: the fan module is running, and the water release module is closed. Under the action of the fan module, the ambient air passes through the desiccant module and then is blown toward the generation module. During the process of the ambient air passing through the desiccant module, the desiccant module absorbs moisture in the air and stores it in the desiccant module; the process of generating hydrated negative ions: the fan module is running, and under the action of the fan module, the ambient air passes through the desiccant module and then is blown toward the generation module. The water release module is running, and the water release module releases the moisture adsorbed by the desiccant module. The released moisture passes through the generation module with the wind beam, thereby increasing the probability of moisture contacting the generation module. In this way, the generation module splits water molecules to generate a large number of hydrated negative ions. The hydrated negative ions enter the environment with the wind beam, thereby improving the ambient air quality. The air treatment equipment saves the user from the operation of manually adding water, and will not increase the ambient humidity, and its practicality is better.
