According to a second aspect of the present invention, there is provided a dehumidifier comprising a controller including a memory and a processor, the memory having stored therein a machine executable program which when executed by the processor is adapted to carry out any one of the above-described dehumidifier control methods.

According to the dehumidifier control method, after the dehumidifier is started, the relative position of the dehumidifier and a user and the air supply speed are obtained. Then, the air flow speed and the air flow humidity of the dehumidified air flow blown to the user by the dehumidifier are calculated, then whether the air flow speed and the air flow humidity meet the preset comfort range is judged, and if the judgment result shows that the air flow speed and the air flow humidity meet the comfort range, the current position of the dehumidifier and the air supply speed can be maintained unchanged. Therefore, the dehumidifier can directly send comfortable and proper dehumidified air flow to the position of the user, thereby ensuring the dehumidification effect and improving the use experience of the user.

Further, in the dehumidifier control method of the invention, if the air flow speed is found to be less than the preset comfort range, the air supply speed of the dehumidifier is preferably adjusted. By increasing the air supply speed, the air flow can be accelerated, so that the air flow speed is closer to the comfort range expected by the user. Conversely, if the airflow rate is too high, the supply air speed may be reduced appropriately to provide a softer supply air experience. If the air flow speed is found to meet the preset comfort range, but the air flow humidity is still unsatisfactory, the self-position of the dehumidifier is adjusted. This is because, even if the supply air speed is appropriate, if the distance between the dehumidifier and the user is not appropriate, the air flow humidity may be excessively high or excessively low. Through the position of fine setting dehumidifier, can control the distribution of air current better to optimize air current humidity, make it reach the comfortable scope of predetermineeing.

Further, according to the dehumidifier control method, by acquiring the real-time weather of the current geographic position of the user, whether the current weather type belongs to overcast and wet or hot and wet can be determined, and if the weather type is overcast and wet, the dehumidifier is controlled to enter a heating and dehumidifying mode, so that the indoor warmth is kept while the moisture is removed, and the comfort level of the user is improved; if the weather type is hot and humid, the dehumidifier is controlled to enter a cooling and dehumidifying mode, so that not only can the humidity be effectively removed, but also the indoor temperature can be reduced, and a cool and comfortable environment is provided for users. The invention combines real-time weather to make the control of the dehumidifier more intelligent and accurate, which not only improves the dehumidification effect, but also better satisfies the use requirements of users under different weather conditions and creates more comfortable and healthy living space for the users.

Indeed, various modifications and variations of the present invention will be apparent to those of ordinary skill in the art without departing from the scope or spirit of the present invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield still further embodiments. Accordingly, it is intended that the present invention cover such modifications and variations as come within the scope of the appended claims and their equivalents.

In the description of the present embodiment, it is to be understood that the term "plurality" means at least two, for example, two, three, etc. Unless explicitly specified otherwise. When a feature "comprises or includes" a feature or some of its coverage, this indicates that other features are not excluded and may further include other features, unless expressly stated otherwise.

In the description of the present embodiment, the descriptions of the terms "one embodiment," "some embodiments," "some examples," "one example," and the like mean that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

In order to solve the above problems, the present invention provides a dehumidifier control method, and fig. 1 is a flowchart of a dehumidifier control method according to an embodiment of the present invention, and as shown in fig. 1, the dehumidifier control method at least includes the following steps S101 to S104.

Step S101, starting the dehumidifier, and acquiring the relative position of the dehumidifier and a user and the air supply speed.

The user can start the dehumidifier through modes such as a remote controller, a mobile phone APP, an intelligent voice assistant, function keys and the like, so that the dehumidifier enters a working state.

The indoor position of the dehumidifier can be determined through a built-in sensor and a positioning technology, and the indoor position of the user can be identified through an infrared sensor, a camera or various wearable devices.

Step S102, respectively calculating the air flow speed and the air flow humidity of the dehumidified air flow blown to the user by the dehumidifier.

On the premise that the relative position of the dehumidifier and a user and the air supply speed are known, the air flow speed and the air flow humidity of the dehumidified air flow blown to the user by the dehumidifier can be calculated in various modes.

For example, the simulated dehumidifier blows the dehumidified air flow to the user at different positions from the user at different air supply speeds, the air flow speed and the air flow humidity of the dehumidified air flow are measured at the position of the user, and a large amount of experimental data are stored and used as data references for calculating the air flow speed and the air flow humidity at this time.

Or by constructing an air flow model and combining a humidity distribution rule, calculating the speed change and the humidity change of the dehumidifying air flow in the transmission process, thereby obtaining the air flow speed and the air flow humidity when the dehumidifying air flow is blown to a user.

Step S103, judging whether the air flow speed and the air flow humidity meet the preset comfort range.

The preset comfort range is carefully set according to a large number of experiments and user feedback data, and aims to ensure that the dehumidifying air flow can achieve an effective dehumidifying effect and can not cause discomfort to a user. For example, the comfortable range of the air flow speed is 0.2 m/s-2 m/s, and the comfortable range of the air flow humidity is 40% -60%. Of course, the user can set the comfort range with pertinence according to his own preference or demand.

And step S104, if yes, maintaining the current position and the current wind speed of the dehumidifier. This means that no adjustments are made to the dehumidifier, ensuring that the airflow rate and the airflow humidity at the location of the user remain within the comfort range.

The dehumidifier control method of the embodiment can directly send comfortable and proper dehumidified airflow to the position of the user, thereby ensuring the dehumidification effect and improving the use experience of the user. Meanwhile, the dehumidifier can be kept in the optimal working state by maintaining the current position and the current wind speed of the dehumidifier, so that unnecessary energy loss is effectively reduced, and the design concept of energy conservation and environmental protection is embodied.

Fig. 2 is a flowchart of adjusting a dehumidifying mode of the dehumidifier, which may include the following steps S201 to S204, as shown in fig. 2, according to an embodiment of the present invention.

Step S201, acquiring real-time weather of the current geographic location of the user.

For example, the dehumidifier may obtain the current geographical location of the user through a built-in positioning function, and may query for local weather information through networking, which typically includes temperature, humidity, wind direction, wind speed, weather conditions (e.g., sunny, rainy, etc.), and so on.

Step S202, determining weather types of real-time weather, wherein the weather types comprise cool humidity and hot humidity.

Specifically, the temperature and humidity of the current weather can be analyzed, and if the temperature is lower and the humidity is higher, the weather is determined as overcast and humid weather; if the temperature is higher and the humidity is also higher, it is determined as a hot humid weather.

And step S203, if the weather type is cool and humid, controlling the dehumidifier to enter a heating and dehumidifying mode.

When determining that the current is cool and humid weather, the automatic control dehumidifier can enter a heating dehumidification mode, and the air outlet temperature of the dehumidifier is increased in the heating dehumidification mode, so that the indoor warmth is kept while the humidity is removed, and the comfort level of a user is improved.

Step S204, if the weather type is hot and humid, controlling the dehumidifier to enter a cooling and dehumidifying mode.

When determining that the current is hot humid weather, can the automatic control dehumidifier get into cooling dehumidification mode, the air-out temperature of dehumidifier reduces under the cooling dehumidification mode, both can effectively get rid of the moisture, can reduce indoor temperature again, provides cool comfortable environment for the user.

The process of adjusting the dehumidifying mode of the dehumidifier may be performed after the step of starting the dehumidifier and before the step of acquiring the relative position of the dehumidifier and the user and the supply wind speed, so that the dehumidifier may be quickly brought into the dehumidifying mode conforming to the current weather type.

In some embodiments, after the relative position of the dehumidifier and the user and the wind speed of the air supply are obtained, it may be further determined whether the dehumidified airflow blown out by the dehumidifier can reach the user. The aim of this step is to ensure that the dehumidified air flow can directly act on the user, and the effect of the dehumidified air flow is fully exerted. If the dehumidified airflow can directly reach the user, the following steps are executed, namely the airflow speed and the airflow humidity of the dehumidified airflow blown to the user by the dehumidifier are respectively calculated. If the dehumidification air flow cannot directly reach the user, the air supply speed of the dehumidifier needs to be adjusted, the air flow coverage area is enlarged, and therefore the air flow can reach the user more effectively.

In one example, the step of determining whether the dehumidified airflow blown out by the dehumidifier can reach the user directly may be: acquiring the air supply distance of the dehumidifier at the current air supply speed, comparing the air supply distance with the actual distance between the dehumidifier and a user, and determining that the dehumidified air flow can directly reach the user if the air supply distance is greater than (or equal to) the actual distance between the dehumidifier and the user; if the air supply distance is smaller than the actual distance between the dehumidifier and the user, the dehumidified airflow can be determined to directly reach the user.

Further, before the step of obtaining the air supply distance of the dehumidifier at the current air supply speed, the method may further include: acquiring the air outlet direction of the dehumidifier, judging whether the air outlet direction of the dehumidifier faces a user, and if the air outlet direction faces the user, executing the step of acquiring the air supply distance of the dehumidifier at the current air supply speed; if the air outlet direction does not face the user, the air outlet direction of the dehumidifier needs to be adjusted first, so that the air outlet direction faces the user.

The judgment of the air outlet direction of the dehumidifier is crucial, and if the air outlet direction does not face the user, even if the air supply speed and the air supply distance are proper, the dehumidified air flow cannot be effectively blown to the user. Through judging the air-out direction, can ensure that the air-out direction of dehumidifier, air supply wind speed and air supply distance all can cooperate effectively, make the dehumidification air current blow to the user with shortest route, provide best dehumidification effect and use experience for the user, reduce the loss of dehumidification air current in the flow process, and then reduce the energy loss of dehumidifier.

In some embodiments, in the case that the air flow speed and the air flow humidity cannot simultaneously meet the preset comfort range, if the air flow speed is found to not meet the preset comfort range, the air supply wind speed of the dehumidifier can be tried to be adjusted, and the air supply wind speed is increased or decreased, so that the air flow speed reaches the range that the user feels comfortable. The adjusting process can be automatically adjusted according to personal preference of the user and real-time weather conditions, so that the user can enjoy comfortable air flow in different environments.

Or if the air flow speed is found to meet the preset comfort range, but the air flow humidity still does not meet the requirement, the self-position of the dehumidifier needs to be considered to be adjusted. By changing the position of the dehumidifier, the direction and/or path of the air flow can be changed, thereby more effectively reducing the humidity of the air flow blown to the user.

Fig. 3 is a flowchart of adjusting the self-position of the dehumidifier according to an embodiment of the present invention, and as shown in fig. 3, adjusting the self-position of the dehumidifier may include the following steps S301 to S302.

In step S301, at least one target position is predicted.

The number of target positions may be plural, and the target positions may be characterized in that when the dehumidifier is in the positions, the air flow speed and the air flow humidity of the dehumidified air flow blown out therefrom each satisfy a preset comfort range.

In step S302, the dehumidifier is controlled to move from the current position to one of the target positions.

For example, a target position closest to the current position may be selected as the moving target. Thus, the dehumidifier can reach the target position at the shortest distance and the fastest time, thereby rapidly improving the dehumidification effect of the area where the user is located.

Fig. 4 is a flowchart of controlling movement of the dehumidifier according to an embodiment of the present invention, and as shown in fig. 4, controlling movement of the dehumidifier from a current position to one of target positions may include the following steps S401 to S403.

Step S401, selecting a suitable target position from the predicted at least one target position.

Criteria for selection may include the distance of the target location from the current location, the complexity of the path of movement, the airflow velocity at the target location, whether the target location is occupied, etc. These factors can be comprehensively considered according to a preset priority or algorithm, so that the selected position can be ensured to meet the current dehumidification requirement.

Step S402, a moving path from the current position to the target position is planned for the dehumidifier aiming at the selected target position.

Specifically, a safe and efficient moving path can be planned by using known indoor environment information (such as room layout, obstacle positions, etc.), so as to ensure that the dehumidifier can safely and accurately reach the target position.

Step S403, controlling the dehumidifier to move to the target position according to the planned moving path.

In the moving process, the position and the state of the dehumidifier can be monitored in real time, so that the dehumidifier can be ensured to move according to a preset path. Meanwhile, abnormal situations which may occur, such as an obstacle suddenly appearing in the path, a change in the movement speed of the dehumidifier, etc., are handled.

Through the steps, the system can realize intelligent control and optimization of the position of the dehumidifier, and ensure that the dehumidifier provides efficient dehumidification effect for users at the optimal position. The comfort experience of the user is improved, and the advancement of the intelligent home system in the aspect of environmental control is also demonstrated.

Considering that some types of dehumidifiers need to be used by switching on an indoor power supply through a power line, for this type of dehumidifier, after a step of planning a moving path from a current position to a target position for the dehumidifier, it should also be: and acquiring power line information of the dehumidifier, judging whether the dehumidifier can move from the current position to the target position according to the power line information, if so, executing the step of controlling the dehumidifier to move to the target position according to the planned moving path, and if not, reselecting a proper target position from at least one predicted target position.

Specifically, the power cord information may include a power cord length, a plug position of the power cord plug, and the power cord length, the plug position of the power cord plug may be pre-stored in the device information of the dehumidifier so as to be directly called when in use.

The step of judging whether the dehumidifier can be moved from the current position to the target position according to the power line information may be: the planned movement path is evaluated to check if the distance between the dehumidifier and the power outlet is less than or equal to the length of the power line at any time during the movement of the dehumidifier along the path, and if the distance between the dehumidifier and the power outlet exceeds the length of the power line at any point along the movement path, the path is not viable because the power line may not provide sufficient length to support movement of the dehumidifier. Therefore, a suitable target position needs to be selected again.

According to the scheme, in the process of planning the moving path, factors such as indoor layout, obstacle distribution and the like are fully considered, factors such as the moving capacity of the dehumidifier are also considered, and the safety and the effectiveness of the moving path are ensured.
