Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment control, and in particular to a control method and device for a dehumidifier, and a dehumidifier. Background Art

[0002] Dehumidifiers are currently widely used in industrial settings as humidity-control air conditioners. Due to the unique operating environments of industrial plants, dust inevitably accumulates on the surfaces of industrial dehumidifiers. Furthermore, intermittent or non-continuous use of dehumidifiers can lead to dust accumulation within the air ducts during standby (fan shutdown) periods. The longer the dehumidifier is idle and the harsher the environment, the more severe the dust accumulation. This problem is particularly common in industrial dehumidifiers with non-enclosed air outlets. It can also occur in industrial dehumidifiers with enclosed air outlets that are not fully closed and have gaps. During this period, dust is blown out with the air supply when the dehumidifier is turned on. If personnel are in the air supply area without proper protection, there is a risk of dust injury.

For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0033] In response to the above technical problems, in an embodiment of the present invention, based on the collection of three main parameters: dust concentration, downtime, and personnel location, a logical setting is used to optimize the fan speed input strategy when the fan is started after shutdown to ensure the safety of starting the machine when there is dust accumulation in the air duct. A dust sensor for detecting dust concentration is installed inside the dehumidifier air duct, and an infrared sensor for detecting personnel location is installed on the top of the machine. At the same time, a control logic based on dust concentration, downtime, and personnel location to prevent direct dust blowing, a preset dust concentration limit, a dust concentration safety limit that meets standard requirements, and a preset safety distance between personnel and equipment are written into the remote control system.

[0034] The following describes it in detail with reference to specific embodiments. Example 1

[0035] According to an embodiment of the present invention, a method embodiment of a dehumidifier control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 1 FIG. 1 is a flow chart of a method for controlling a dehumidifier according to an embodiment of the present invention. Figure 1 As shown, the control method of the dehumidifier includes the following steps:

[0037] Step S102, based on the duration corresponding to the predetermined period and the average value of the ambient dust in the area where the dehumidifier is located during the predetermined period, determine the current dust accumulation level of the dehumidifier air duct, wherein the predetermined period is the period corresponding to the first moment when the dehumidifier receives the shutdown command and the second moment when the dehumidifier receives the start-up command, and the first moment is the moment before the second moment.

[0038] Optionally, the predetermined time period may be the time period between when the dehumidifier receives a shutdown instruction and when it receives a start-up instruction again.

[0039] In this embodiment, a dust sensor for detecting dust concentration is provided in the area where the dehumidifier is located. When the dehumidifier responds to the shutdown instruction, the dust sensor is triggered to start detecting dust concentration in the area where the dehumidifier is located.

[0040] The dust concentration in the area where the dehumidifier is located, collected by the dust sensor, can be used to determine the average value of ambient dust in the area. The average value of ambient dust here can be expressed as the average value of ambient dust concentration.

[0041] The first moment is the moment when the dehumidifier receives a stop instruction, and the second moment is the moment when the dehumidifier receives a start instruction.

[0042] In this embodiment, the current dust accumulation level in the dehumidifier duct can be determined based on the average ambient dust level. For example, the ambient dust accumulation level can be subdivided into low dust accumulation, medium dust accumulation, high dust accumulation, and severe dust accumulation according to pre-set logic in the control program. It should be noted that different fan startup strategies are adopted for different dust accumulation levels.

[0043] Step S104 : determining a target control strategy for the dehumidifier based on the current dust accumulation level, wherein the target control strategy is a dehumidifier control method preset based on the dust accumulation level.

[0044] In this embodiment, the target control strategy of the dehumidifier is determined according to the current dust accumulation level of the dehumidifier air duct determined in step S102 to improve the accuracy of dehumidifier control while also reducing hazards to personnel.

[0045] Step S106: controlling the dehumidifier to execute instructions corresponding to the target control strategy.

[0046] As can be seen from the above, in an embodiment of the present invention, after the dehumidifier receives a shutdown command, it can start to use the dust sensor to collect the ambient dust concentration in the area where the dehumidifier is located. When the dehumidifier receives a start command again, the ambient dust concentration collected by the dust sensor is used to determine the average ambient dust concentration in the area where the dehumidifier is located. Then, based on the average ambient dust concentration, the dust accumulation level of the dehumidifier air duct is determined, and based on the dust accumulation level, the target control strategy of the dehumidifier in this startup is determined, and the dehumidifier is controlled to execute instructions corresponding to the target control strategy. On the basis of the original control logic of the dehumidifier, a control logic is added to determine the degree of dust accumulation in the air duct based on the average dust concentration and the fan downtime, so as to determine the operating strategy after the dehumidifier is shut down and restarted. This effectively avoids the risk of dust in the air duct being blown out and causing dust hazards to personnel due to excessive fan speed when there is a lot of dust accumulation, and also improves the safety and reliability of the dehumidifier operation. In addition, it can also prevent the air duct dust from being blown out in a concentrated manner in a short period of time and causing personal injury.

[0047] It is easy to notice that the control logic of the dehumidifier has been added with the addition of determining the degree of dust accumulation in the air duct by collecting dust concentration and fan downtime, and at the same time subdividing the degree of environmental dust accumulation, and determining the strategy for investing the fan speed when the dehumidifier is restarted after being shut down in standby mode. This can be used to prevent the dust in the air duct from being blown out in a concentrated manner in a short period of time and causing personal injury.

[0048] Therefore, the technical solution provided in Example 1 of the present invention solves the technical problem in the related art that dust is easily attached to the air duct of the industrial dehumidifier, and when the machine is turned on, the dust will be blown out with the air supply, which may easily cause dust damage to on-site personnel.

[0049] According to the above embodiment of the invention, based on the duration corresponding to the predetermined time period and the average value of environmental dust in the area where the dehumidifier is located during the predetermined time period, it can include: when a shutdown command is received, triggering the timer to start timing from the first moment; stopping timing when a start command is received, and counting the duration from the first moment to the second moment; obtaining the amount of environmental dust in the predetermined time period corresponding to the first moment and the second moment; and determining the average value of environmental dust based on the duration and the amount of environmental dust.

[0050] In this embodiment, after the dehumidifier has been in standby mode for a period of time in a dusty industrial plant, it receives a start-up instruction (i.e., a start-up instruction). During this period, the dust sensor continuously collects dust concentration and dust time in the environment, and calculates the fan downtime t and the average ambient dust concentration φ during the downtime period (i.e., the average ambient dust value) as of the receipt of the start-up instruction.

[0051] For dehumidifiers, the degree of environmental dust accumulation can be first subdivided according to historical data within a historical time period. For example, it can be divided into low dust accumulation, medium dust accumulation, high dust accumulation, and severe dust accumulation. Different fan startup strategies can be adopted for different dust accumulation degrees. That is, a control strategy set can be generated in advance, and the control strategy set here can include multiple control strategies. Figure 2 is a flow chart of an optional dehumidifier control method according to an embodiment of the present invention, Figure 2 Where φ is the average ambient dust concentration during the shutdown period (i.e., the ambient dust average value); φ1 is the preset dust concentration limit (i.e., the first ambient dust threshold); φ0 is the dust concentration safety limit that meets the standard requirements (i.e., the second ambient dust threshold); t is the fan shutdown time (i.e., the predetermined period); t1 is the preset fan shutdown time limit (i.e., the first preset duration); L1 is the preset safety distance between personnel and equipment (i.e., the predetermined distance); V1 is the preset fan startup speed (i.e., the first predetermined speed); Vx is the preset dust operating speed after the fan speed is increased. The corresponding wind speed carries a small amount of dust, but the concentration does not exceed the safety limit (i.e., the second predetermined speed). The following is a detailed explanation with reference to the accompanying drawings.

[0052] According to the above embodiment of the present invention, before determining the target control strategy of the dehumidifier based on the current dust accumulation level, the control method of the dehumidifier may further include: generating a control strategy set including the target control strategy; wherein, generating the control strategy set including the target control strategy includes: when the dust accumulation level is low dust accumulation, generating a first control strategy, wherein the low dust accumulation indicates that the duration is less than the first preset duration, and the average value of the ambient dust is less than the first ambient dust threshold, and the first control strategy is to control the dehumidifier fan to operate at a set wind speed; when the dust accumulation level is medium dust accumulation or high dust accumulation, obtaining the distance between the target object in the area where the dehumidifier is located and the dehumidifier, based on the distance A second control strategy and a third control strategy are generated, wherein the duration of medium dust accumulation is not less than the first preset duration, and the average value of ambient dust is less than the first ambient dust threshold; the duration of high dust accumulation is less than the first preset duration, and the average value of ambient dust is not less than the first ambient dust threshold. The second control strategy and the third control strategy are to control the dehumidifier fan to operate according to the operation control strategy corresponding to the distance; when the dust accumulation level is severe dust accumulation, a fourth control strategy is generated, wherein the duration of severe dust accumulation is not less than the first preset duration, and the average value of ambient dust is not less than the first ambient dust threshold. The fourth control strategy is to perform a cleaning action on the dehumidifier based on the cleaning instruction.

[0053] The target objects may be people in the area where the dehumidifier is located.

[0054] Optionally, an infrared sensor may be provided in the area where the dehumidifier is located to detect the distance between a person and the dehumidifier air duct.

[0055] like Figure 2 As shown, the downtime of the dehumidifier fan can be obtained, and the average ambient dust concentration φ during the dehumidifier downtime can be calculated; then the operation control strategy is determined by comprehensively considering the fan downtime and the average ambient dust concentration during the downtime.

[0056] In this embodiment, when t<t1, φ<φ1, that is, the ambient dust concentration is low during the downtime period, which is low dust accumulation and the degree of dust accumulation is slight, and the fan starts normally at this time (that is, the first control strategy); when t≥t1, φ≥φ1, that is, the ambient dust concentration is high during the long downtime period, which is serious dust accumulation and the degree of dust accumulation is serious, the machine issues a cleaning reminder, the fan does not start, and after the cleaning is completed and the reminder is canceled by pressing the button, the fan starts normally to the set wind speed (that is, the fourth control strategy).

[0057] When t ≥ t1 and φ < φ1, it is determined to be medium dust accumulation (corresponding to the second control strategy). When t < t1 and φ ≥ φ1, it is determined to be high dust accumulation (corresponding to the third control strategy). For medium or high dust accumulation, the system can be activated in a predetermined manner. The details are explained below.

[0058] When the dust accumulation level is medium dust accumulation, a second control strategy is generated based on the distance, including: when it is determined that the distance is less than the predetermined distance, a second control strategy is generated, wherein the second control strategy is to control the dehumidifier fan to run at a first predetermined speed for a second preset time, and continue to run at the second predetermined speed for a third preset time, and when it is determined that the new environmental dust concentration in the area where the dehumidifier is located is less than the second environmental dust threshold, the fan is controlled to run at the set wind speed; when it is determined that the distance is not less than the predetermined distance, a second control strategy is generated, wherein the second control strategy is to control the dehumidifier fan to run at the first predetermined speed for a second preset time, and then control the fan to run at the set wind speed.

[0059] In this embodiment, when t≥t1, φ<φ1, that is, the ambient dust concentration is low during a long shutdown time and the dust accumulation is at a medium level, a strategy of starting at a low speed and slowly increasing the speed is required to avoid a large amount of dust being blown out. Under this condition, the distance L between the personnel and the equipment needs to be collected synchronously. The operation strategy is further refined according to the distance between the personnel and the equipment. Among them, ① when L ≥ L1, that is, the distance is greater than the safe distance, the speed is started at V1, and after running for t2 minutes, the speed is increased to the set wind speed (i.e., the second-first control strategy); ② when L < L1, that is, the distance is less than the safe distance, the speed is first started at V1 and run for t2 minutes. At this time, the speed setting is low and does not cause dust to be blown out; then the speed is gradually increased to VX. At this time, the wind speed carries out a small amount of dust, but the concentration does not exceed the safety limit. Run for t3 minutes, continue to detect the dust concentration φ' in the air, and compare it with the safety limit φ0. If it is lower than the safety limit, the speed can be increased to the set wind speed. If it is still higher than the safety limit φ0, continue to run at VX for t3 minutes until the concentration is lower than the safety limit φ0 (i.e., the second-second control strategy).

[0060] When the dust accumulation level is high, a third control strategy is generated based on the distance, including: when it is determined that the distance is less than the predetermined distance, a thirty-first control strategy is generated, wherein the thirty-first control strategy is to control the dehumidifier fan to reverse and run at the first predetermined speed for the second preset time and then stop, and after starting, run at the first predetermined speed for the second preset time, and continue to run at the second predetermined speed for the third preset time. When it is determined that the new environmental dust concentration in the area where the dehumidifier is located is less than the second environmental dust threshold, the fan is controlled to run at the set wind speed; when it is determined that the distance is not less than the predetermined distance, a thirty-second control strategy is generated, wherein the thirty-second control strategy is to control the dehumidifier fan to run at the first predetermined speed for the second preset time and then control the fan to run at the set wind speed.

[0061] In this embodiment, when t<t1, φ≥φ1, that is, the machine is shut down for a period of time in high-concentration dust and the dust accumulation is at a high level, it is necessary to adopt a strategy of first reversing the motor at a low speed, then starting at a low speed, and slowly increasing the speed to avoid a large amount of dust being blown out. Under this condition, the distance L between the person and the dehumidifier must be collected simultaneously. The operation strategy is further refined based on the distance between the person and the equipment. ① When L ≥ L1, that is, the distance is greater than the safe distance, the dehumidifier is started at speed V1, runs for t2 minutes, and then increases the speed to the set wind speed (i.e., the third-first control strategy). ② When L < L1, that is, the distance is less than the safe distance, the dehumidifier is first started at speed V1 in reverse direction for t2 minutes. At this time, the speed setting is low and does not cause dust to be blown out. The reverse start is adopted to avoid dust escape caused by direct start in high dust accumulation conditions. The dehumidifier is then started at speed V1 for t2 minutes, and the speed is gradually increased to VX. At this time, the wind speed carries a small amount of dust, but the concentration does not exceed the safety limit. The speed is continued for t3 minutes, and the dust concentration φ' in the air is continuously monitored and compared with the safety limit φ0. If it is below the safety limit, the speed is increased to the set wind speed. If it is still above the safety limit φ0, the dehumidifier continues to run at VX for t3 minutes until the concentration is below the safety limit φ0 (i.e., the third-second control strategy).

[0062] That is, in an embodiment of the present invention, when it is determined that the new environmental dust concentration in the area where the dehumidifier is located is not less than the second environmental dust threshold, the fan of the dehumidifier continues to be controlled to continue running at the second predetermined speed for the third preset time period.

[0063] When the dehumidifier is under severe dust accumulation, after completing the cleaning of the dehumidifier, control the dehumidifier to run at the set wind speed.

[0064] According to the above embodiment of the present invention, controlling the dehumidifier to execute instructions corresponding to the target control strategy includes: when the target control strategy is the first control strategy, controlling the fan of the dehumidifier to operate at a set wind speed; when the target control strategy is the second-first control strategy, controlling the fan to operate at a first predetermined speed for a second preset time, and continuing to operate at the second predetermined speed for a third preset time, when it is determined that the new environmental dust concentration is less than the second environmental dust threshold, controlling the fan to operate at the set wind speed; when the target control strategy is the second-second control strategy, controlling the fan to operate at the first predetermined speed for the second preset time, and then controlling the fan to operate at the set wind speed; When it is determined that the target control strategy is the thirty-first control strategy, the fan is controlled to reverse and run at the first predetermined speed for the second preset time and then stop, and after starting, it runs at the first predetermined speed for the second preset time, and continues to run at the second predetermined speed for the third preset time. When it is determined that the dust concentration in the new environment is less than the second environmental dust threshold, the fan is controlled to run at the set wind speed; when it is determined that the target control strategy is the thirty-second control strategy, the fan is controlled to run at the first predetermined speed for the second preset time, and then the fan is controlled to run at the set wind speed; when it is determined that the target control strategy is the fourth control strategy, the cleaning action of the dehumidifier is performed based on the cleaning instruction.

[0065] That is, when it is determined that the first control strategy is adopted to control the dehumidifier, the fan of the dehumidifier runs at the set wind speed based on the first control strategy; when it is determined that the second control strategy is adopted to control the dehumidifier, the fan of the dehumidifier runs at the first predetermined speed for the second preset time, and continues to run at the second predetermined speed for the third preset time, and when it is determined that the dust concentration in the new environment is less than the second environmental dust threshold, it runs at the set wind speed; when it is determined that the second control strategy is adopted to control the dehumidifier, the fan of the dehumidifier runs at the first predetermined speed for the second preset time, and then runs at the set wind speed; when it is determined that the third control strategy is adopted to control the dehumidifier, the fan of the dehumidifier runs at the first predetermined speed for the second preset time, and then runs at the set wind speed; When the dehumidifier is controlled by the strategy, the fan of the dehumidifier reverses and runs at the first predetermined speed for the second preset time and then stops, and after starting, runs at the first predetermined speed for the second preset time, and continues to run at the second predetermined speed for the third preset time. When it is determined that the dust concentration in the new environment is less than the second environmental dust threshold, it runs at the set wind speed again; when it is determined that the third control strategy is adopted to control the dehumidifier, the fan of the dehumidifier runs at the first predetermined speed for the second preset time, and then runs at the set wind speed; when it is determined that the fourth control strategy is adopted to control the dehumidifier, the cleaning action of the dehumidifier is performed based on the cleaning instruction.

[0066] In this approach, the degree of dust accumulation in the air duct is determined based on the average dust concentration and fan downtime. The distance between the personnel and the prototype unit is also used to determine the operational strategy for restarting the equipment after shutdown. By collecting dust concentration, downtime, and personnel location parameters, a strategy for adjusting the fan speed when restarting a dehumidifier after a standby shutdown in industrial settings is determined to prevent direct blown dust from the air duct.

[0067] In the embodiment of the present invention, the dehumidifier is an industrial dehumidifier. Of course, it can also be other household dehumidifiers, which is not specifically limited here.

[0068] For example, in industrial dehumidifiers with non-enclosed air outlets used in industrial settings, dust from the factory environment will accumulate in the air duct after the fan stops, which can easily cause harm to personnel after restart. Therefore, in an embodiment of the present invention, when the equipment is restarted after a period of downtime, a control logic is developed to prevent direct dust blowing by collecting dust concentration, downtime, and personnel location. This avoids excessive fan speed when dust accumulates, causing dust to be blown out of the air duct, thereby improving the operational safety and reliability of the dehumidifier.

[0069] Through the technical solution provided in Example 1 of the present invention, the control logic is designed to adjust the fan starting speed and status based on dust concentration, dust time, and personnel position. That is, the dust accumulation degree of the air duct is determined by collecting dust concentration and fan shutdown time, and the environmental dust accumulation degree is subdivided at the same time. At the same time, the personnel position is collected, and according to different personnel position distances, the fan speed investment strategy when the equipment is restarted after being shut down in standby is comprehensively determined, so as to avoid the occurrence of excessive fan speed when there is a lot of dust accumulation, causing dust to be blown out of the air duct, thereby improving the safety and reliability of the dehumidifier operation.

[0070] It should be noted that for the aforementioned method embodiments, for the sake of simplicity, they are all expressed as a series of action combinations, but those skilled in the art should be aware that this application is not limited by the order of the actions described, because according to this application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by this application.

[0071] Through the description of the above embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus the necessary general hardware platform. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the existing technology, can be embodied in the form of a software product. The computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application. Example 2

[0072] According to an embodiment of the present invention, a dehumidifier control device for implementing the above-mentioned dehumidifier control method is also provided. Figure 3 Schematic diagram of a control device for a dehumidifier according to an embodiment of the present invention. Figure 3 As shown, the device includes: a first determining unit 31 , a second determining unit 33 and a control unit 35 .

[0073] Among them, the first determination unit 31 is used to determine the current dust accumulation level of the dehumidifier air duct based on the duration corresponding to the predetermined time period and the average value of the ambient dust in the area where the dehumidifier is located during the predetermined time period, wherein the predetermined time period is the time period corresponding to the first moment when the dehumidifier receives the shutdown command and the second moment when the dehumidifier receives the start command, and the first moment is the moment before the second moment.

[0074] The second determining unit 33 is configured to determine a target control strategy for the dehumidifier based on the current dust accumulation level, wherein the target control strategy is a dehumidifier control mode preset based on the dust accumulation level.

[0075] The control unit 35 is used to control the dehumidifier to execute instructions corresponding to the target control strategy.

[0076] It should be noted here that the above-mentioned first determination unit 31, second determination unit 33 and control unit 35 correspond to steps S102 to S106 in Example 1. The three modules and the corresponding steps implement the same instances and application scenarios, but are not limited to the contents disclosed in the above-mentioned Example 2.

[0077] As can be seen from the above, in the scheme described in Example 2 of the present invention, a first determination unit can be used to determine the current dust accumulation level in the dehumidifier air duct based on the duration corresponding to a predetermined period and the average value of ambient dust in the area where the dehumidifier is located during the predetermined period, wherein the predetermined period is the period corresponding to the first moment when the dehumidifier receives a shutdown command and the second moment when the dehumidifier receives a startup command, with the first moment being the moment before the second moment. A second determination unit is then used to determine a target control strategy for the dehumidifier based on the current dust accumulation level, wherein the target control strategy is a dehumidifier control method pre-set based on the dust accumulation level. The control unit is then used to control the dehumidifier to execute the instructions corresponding to the target control strategy. Based on the original control logic of the dehumidifier, control logic is added that determines the degree of dust accumulation in the air duct based on the average dust concentration and the fan downtime, thereby determining the operating strategy for the dehumidifier after it is shut down and then restarted. This effectively avoids the risk of dust hazard to personnel caused by excessive fan speed when dust accumulation is high, while also improving the safety and reliability of the dehumidifier's operation. In addition, it can also prevent the dust in the air duct from being blown out in a concentrated manner in a short period of time and causing personal injury.

[0078] It is easy to notice that the control logic of the dehumidifier has been added with the addition of determining the degree of dust accumulation in the air duct by collecting dust concentration and fan downtime, and at the same time subdividing the degree of environmental dust accumulation, and determining the strategy for investing the fan speed when the dehumidifier is restarted after being shut down in standby mode. This can be used to prevent the dust in the air duct from being blown out in a concentrated manner in a short period of time and causing personal injury.

[0079] Therefore, the technical solution provided in Example 2 of the present invention solves the technical problem in the related art that dust is easily attached to the air duct of the industrial dehumidifier, and when the machine is turned on, the dust will be blown out with the air supply, which may easily cause dust damage to on-site personnel.
