Description
Technical Field
The invention relates to the technical field of dehumidifiers, in particular to an automatic control method of a dehumidifier, a computer readable storage medium and the dehumidifier.
Background
Dehumidifiers are also known as dehumidifiers, dryers, dehumidifiers. Generally, a dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a cabinet, and a controller. The working principle is as follows: the wet air is pumped into the machine by a fan and passes through a heat exchanger, water molecules in the air are condensed into water drops, the treated dry air is discharged out of the machine, and the indoor humidity is kept at the proper relative humidity by circulation.
With the development of science and technology, the dehumidifier is not only widely applied to the industrial field, but also gradually occupies an irreplaceable position in the field of smart homes. Wherein, in comparatively humid environment, humid air can make the clothing article in the sunning be in moist state always, so can lead to going mildy for a long time, and the user need pay attention to dampproofing.
In the past, when a dehumidifier is used for drying clothes, a drying mode needs to be manually selected. In addition, even if the clothes are dried, the drying mode is not automatically stopped, thereby causing unnecessary energy waste.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an automatic control method of a dehumidifier, which simply realizes the automatic operation of a drying mode during the starting of the dehumidifier and simultaneously prevents clothes from being excessively dried.
In order to achieve the purpose, the invention adopts the following technical scheme:
an automatic control method for a dehumidifier includes presetting a surface temperature threshold of clothes to be dried, judging whether the clothes to be dried exist or not by detecting surface temperature data of the clothes to be dried, starting a drying mode if the clothes to be dried exist, exiting the drying mode when the surface temperature of the clothes to be dried meets a drying requirement, entering a standby mode, detecting the surface temperature data of the clothes to be dried at intervals under the standby mode to judge whether the clothes to be dried exist or not, entering a dehumidification mode if the clothes to be dried do not exist, detecting air relative humidity data of a space where the clothes to be dried exist in real time, and adjusting the working state of the dehumidifier according to the relative humidity data. The dehumidifier and the control method thereof can automatically run the drying mode as long as the dried clothes exist, do not need manual selection of a user, improve the use experience of the user and simultaneously prevent the clothes from being excessively dried.
Further, the preset surface temperature threshold of the dried laundry is specifically: two dried laundry surface temperature thresholds are preset, St1 and St2, respectively, where St2 > St 1. Two preset temperature thresholds, one is used as a judgment condition for starting the drying mode, and the other is used as a judgment condition for exiting the drying mode, so that automatic drying is realized, and excessive drying is effectively prevented.
Further, the preset surface temperature threshold of the dried laundry is specifically: the temperature difference threshold values delta T1 and delta T2 of the surface temperature of the dried clothes and the current indoor temperature T1 are preset, and two dried clothes surface temperature threshold values St1 and St2, St1= T1-delta T1, St2= T1-delta T2 are analyzed and calculated. Considering that the indoor air temperature T1 changes correspondingly with the transition of the four seasons, the user needs to change the setting of the surface temperature thresholds St1, St2 of the dried laundry many times, and in order to reduce the setting times of the user, the surface temperature thresholds St1, St2 of the dried laundry may not be preset directly, but the temperature difference thresholds Δ T1, Δ T2 of the preset surface temperatures St1, St2 of the dried laundry and the current indoor temperature T1 are selected; thus, even if the indoor temperature T1 changes with the change of season, the surface temperatures St1 and St2 of the clothes to be dried can be obtained by subtracting the temperature difference threshold values Δ T1 and Δ T2 from the current indoor temperature T1.
Further, the determining whether the dried laundry exists by detecting the surface temperature data of the dried laundry is specifically: and detecting the surface temperature T of the clothes in the air outlet range of the dehumidifier, and if T is less than St1, judging that the dried clothes exist. The real-time temperature of the detected clothes is compared with the temperature threshold to judge whether the clothes need to be dried, and when the real-time temperature is less than the temperature threshold St1, the clothes are in a relatively wet condition, and the clothes need to be dried.
Further, the exiting the drying mode when it is detected that the surface temperature of the dried laundry meets the drying requirement specifically includes: and detecting the surface temperature T of the clothes in the air outlet range of the dehumidifier, if T is more than St2, judging that the drying is finished, and exiting the drying mode. When the real-time temperature of the laundry is greater than the preset temperature threshold St2, indicating that the drying of the laundry is completed, the drying mode does not need to be continuously turned on, preventing the laundry from being excessively dried.
Further, the determining whether the dried laundry exists by detecting the surface temperature data of the dried laundry is specifically: and detecting the surface temperature T of clothes in the air outlet range of the dehumidifier, if the T is more than or equal to St1, judging that the dried clothes do not exist, entering a dehumidification mode, detecting the relative humidity data of the air in the space in real time, and adjusting the working state of the dehumidifier according to the relative humidity data. When the real-time temperature is higher than the temperature threshold St1, the clothes are in a relatively dry state, the clothes do not need to be dried, and the dehumidifier is prevented from doing useless work.
Further, the adjusting the operating state of the dehumidifier according to the relative humidity data specifically includes: and the detected relative air humidity data gradually rises, and then the temperature of the clothes in the air outlet air-out range is detected. The rise of the relative humidity data indicates that the humidity of the current space is high, and under the condition, the clothes are easy to be wet, and new clothes to be dried are likely to appear, so that the temperature of the clothes needs to be detected circularly, and the clothes are ensured to be dried timely and quickly.
Further, the adjusting the operating state of the dehumidifier according to the relative humidity data specifically includes: and stopping the dehumidification mode when the detected relative humidity data of the air gradually decrease. The relative humidity data is reduced, and the humidity range which is comfortable for human body is reached, the dehumidification mode is stopped, and the condition of excessive dryness in the room is prevented.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of the present invention.
Example 1: an automatic control method for a dehumidifier.
An automatic control method of a dehumidifier specifically comprises the following steps:
the user installs corresponding app through intelligent terminals such as cell-phones, according to self demand, predetermines the surface temperature threshold value of being dried clothing. Further, the app setup page has other parameters for the user to set, in addition to the surface temperature threshold of the laundry being dried. Moreover, the setting can be repeated, so that as the use times of the user increase, the optimal parameter setting can be realized by combining the drying condition of the dried clothes, the self requirement, the local environment, the use habit and other factors. The setting content can be saved each time, and the trouble of repeated operation is avoided. Meanwhile, the set content is transmitted to the control unit 5 of the dehumidifier and stored in the memory module.
There are two surface temperature thresholds for the laundry being dried, St1 and St2, respectively. St1 is the maximum surface temperature value for determining whether to enter the drying mode, and St2 is the minimum surface temperature value for determining whether to end the drying mode. The surface temperature threshold of the laundry to be dried is set based on the current indoor air temperature T1.
After the dehumidifier is powered on and before the dehumidifier is started to operate, the display screen of the operation unit 4 displays the current indoor air temperature T1 and the relative humidity of the indoor air, and the setting interfaces of apps of intelligent terminals such as mobile phones and the like are synchronously displayed.
When the surface temperature threshold of the dried clothes is preset by the user, the setting page of the app has a relevant setting prompt or a recommended value, and the app can be referred by the user, so that the user can conveniently set the app according to the requirements of the user.
When a user starts the dehumidifier, the control module of the control unit 5 controls the dehumidifier to be in a standby state, and during the standby state, the dehumidifier enters a surface temperature detection mode, and the surface temperature of objects in the air outlet range in the vertical and horizontal directions of the air outlet is detected through the temperature detection unit. The purpose of doing so is in order to improve surface temperature detection accuracy, avoid because the relevant operation of dehumidifier leads to the surface temperature of object in the air-out scope and the air temperature of its periphery to change.
The temperature detection unit detects the surface temperature of objects in the air outlet range in the vertical and horizontal directions of the air outlet, outputs a thermal image of temperature distribution, and feeds the thermal image back to the judgment module of the control unit 5. The judging module of the control unit 5 judges whether the surface temperature of the object in the currently detected air-out range is less than the preset surface temperature threshold St1 of the dried clothes by comparing the surface temperature threshold St1 of the dried clothes stored in the memory module of the control unit 5.
When the judging module of the control unit 5 judges that the surface temperature of the object in the air-out range detected before is less than the preset surface temperature threshold St1 of the dried clothes, which means that the dried clothes are detected to exist in the air-out range, the judgment result is fed back to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to automatically enter a drying mode, and controls the air outlet to supply air to the direction of the clothes to be dried.
In the drying mode, the temperature detection unit detects the surface temperature of the dried clothes in real time, outputs a thermal image of temperature distribution, and feeds the thermal image back to the judgment module of the control unit 5, and the judgment module of the control unit 5 judges whether the currently detected surface temperature of the dried clothes is greater than a preset surface temperature threshold St2 of the dried clothes by contrasting the surface temperature threshold St2 of the dried clothes stored in the memory module of the control unit 5.
When the determination module of the control unit 5 determines that the surface temperature of the currently detected dried laundry is greater than the preset surface temperature threshold value St2 of the dried laundry, meaning that the currently detected dried laundry has been dried, the determination result is fed back to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to stop the drying mode and enter a standby state to prevent the dried clothes from being excessively dried. In the standby state, the timing module of the control unit 5 starts immediately, and after a certain time t1 elapses, the timing module feeds back the timing to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to enter a surface temperature detection mode, the surface temperature of objects in the air outlet range in the vertical and horizontal directions of the air outlet is detected through the temperature detection unit, a thermal image of temperature distribution is output and fed back to the judgment module of the control unit 5, and the operation is repeated continuously.
Here, the fixed time t1 needs to be described. t1 can default to factory settings, and the user can also preset in apps of smart terminals such as mobile phones according to the user's needs, such as the number of times of clothes drying each day, time, and the like. the larger t1, the fewer the number of detections by the detection means, which is advantageous for reducing power consumption.
When the judging module of the control unit 5 judges that the surface temperature of the object in the currently detected air-out range is greater than or equal to the preset surface temperature threshold St1 of the dried clothes, which means that there is no dried clothes in the air-out range, the judgment result is fed back to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to automatically enter a dehumidification mode, and controls the air supply direction, the air speed and the like of the air outlet. Under the dehumidification mode, the relative humidity of the indoor air is detected in real time by the humidity detection unit and fed back to the judgment module of the control unit 5. When the judgment module of the control unit 5 judges that the currently detected indoor humidity is gradually increased, which means that there is a possibility of dried clothes in the air outlet range, the judgment result is fed back to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to enter a surface temperature detection mode, detects the surface temperature of objects in the air outlet range in the vertical and horizontal directions of the air outlet through the temperature detection unit, outputs a thermal image of temperature distribution, and feeds the thermal image back to the judgment module of the control unit 5. On the contrary, when the determining module of the control unit 5 determines that the currently detected indoor air relative humidity is not gradually increased but gradually decreased and reaches the humidity range comfortable for human body, the dehumidification mode is stopped and the standby state is entered. In the standby state, the timing module of the control unit 5 starts immediately, and after a certain time t1 elapses, the timing module feeds back the timing to the control module of the control unit 5. The control module of the control unit 5 controls the dehumidifier to enter a surface temperature detection mode, the surface temperature of objects in the air outlet range in the vertical and horizontal directions of the air outlet is detected through the temperature detection unit, a thermal image of temperature distribution is output and fed back to the judgment module of the control unit 5, and the operation is repeated continuously.
Example 2: an automatic control method for a dehumidifier.
The difference from embodiment 1 is that the preset surface temperature threshold of the dried clothes is specifically: the temperature difference threshold values delta T1 and delta T2 of the surface temperature of the dried clothes and the current indoor temperature T1 are preset, and two dried clothes surface temperature threshold values St1 and St2, St1= T1-delta T1, St2= T1-delta T2 are analyzed and calculated. Considering that the indoor air temperature T1 changes correspondingly with the transition of the four seasons, the user needs to change the setting of the surface temperature thresholds St1, St2 of the dried laundry many times, and in order to reduce the setting times of the user, the surface temperature thresholds St1, St2 of the dried laundry may not be preset directly, but the temperature difference thresholds Δ T1, Δ T2 of the preset surface temperatures St1, St2 of the dried laundry and the current indoor temperature T1 are selected; thus, even if the indoor temperature T1 changes with the change of season, the surface temperatures St1 and St2 of the clothes to be dried can be obtained by subtracting the temperature difference threshold values Δ T1 and Δ T2 from the current indoor temperature T1.
