The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example one
The household appliances are in communication connection with a cloud platform, the cloud platform records data information of the household appliances connected with the cloud platform, each household appliance has different use priority levels, and when the total power of the household appliances in use is greater than the rated power of a household line, the cloud platform controls one or more variable frequency appliances in lower use priority levels to perform frequency reduction work according to the use priority levels of the household appliances.
Specifically, all the household appliances are in communication connection with the cloud platform, and an air switch of each household appliance is set at the server end and used for controlling the on-off of the household appliances. The cloud platform collects and records data information of the household appliances connected with the cloud platform, wherein the data information comprises power information and type information of the household appliances. A user can select which electric appliances are connected with the cloud platform, and considering that the influence on a household line is the largest when the high-power electric appliances are used, the user preferably connects all the high-power electric appliances such as an electric cooker, an induction cooker, a hot water kettle, a range hood, a washing machine, a dish washing machine, a disinfection cabinet, an air conditioner, a refrigerator, an electric water heater and the like with the cloud platform. When a plurality of high-power electric appliances are connected to the household line, the rated power of the household line can be exceeded, impact is caused to a household power grid, and potential safety hazards are formed. According to the invention, the household appliances connected with the cloud platform are divided into different use priority levels, and when the total power of the household appliances in use in a family exceeds the rated power of a family line, the cloud platform controls one or more appliances with lower priority use levels to work in a frequency reduction mode. For example, the priority level of the microwave oven is higher than that of the air conditioner and the water heater, and when the microwave oven, the air conditioner and the water heater are used simultaneously to cause overload of the household line, the cloud platform controls the air conditioner and/or the water heater to be used in a frequency reduction mode, so that the power requirement required by the household line is met. Through the design, the invention can reduce the electricity utilization safety risk, and distribute the service time of each electric appliance on the premise of not influencing the use effect of the electric appliance as much as possible so as to ensure that the rated power of a line is not exceeded and the household electricity utilization safety is ensured.
Further preferably, the cloud platform automatically presets the household appliances into a first type of appliance and a second type of appliance according to the types of the household appliances, wherein the second type of appliance is a variable frequency appliance, and the use priority level of the first type of appliance is greater than that of the second type of appliance;
or the user presets the household appliances into a first type of electric appliances and a second type of electric appliances according to the self requirement, wherein the second type of electric appliances are variable frequency electric appliances, and the use priority level of the first type of electric appliances is greater than that of the second type of electric appliances.
Specifically, the cloud platform collects data of each high-power appliance of the connected household appliances by using technologies such as internet, wireless communication and the like, and automatically classifies the household appliances according to types of the household appliances, for example, the appliances which affect results when the household appliances are stopped in short periods in midway, such as an electric cooker, an induction cooker, a hot water kettle, a range hood and the like, are classified into a type of appliances, and the priority of the type of appliances is highest. The general electric appliances with the effect influenced by the pause of the electric appliances such as washing machines, dish washing machines, disinfection cabinets, air conditioners, refrigerators, energy storage water heaters and the like in short term are divided into two types of electric appliances, and the electric appliances are in suboptimal priority.
Or, the user can classify the household appliances connected with the cloud platform according to the user's own needs, for example, if the user thinks that the electric cooker, the induction cooker and the washing machine have a great influence when being stopped for a short time, the appliances can be classified into a type of appliances, and the priority of the type of appliances is highest. Electrical appliances such as a hot water kettle, a range hood, an air conditioner, a water heater and the like stop working within a short time, and the electrical appliances are generally classified into two types of electrical appliances, and the electrical appliances are in suboptimal priority.
At least one of the two types of electric appliances is a variable frequency electric appliance, such as a variable frequency air conditioner, a variable frequency refrigerator, a variable frequency washing machine, a variable frequency disinfection cabinet, a variable frequency water heater, and the like. When the total power of household appliances in use in a household exceeds the rated power of a household line, the cloud platform controls at least one variable frequency appliance in the two types of appliances to work in a variable frequency mode.
Further preferably, the user sets some household appliances as user priority appliances according to actual use requirements, and the use priority level of the user priority appliances is greater than that of one type of appliances.
Specifically, when a user feels that the down-conversion operation or the pause operation of some frequency conversion electric appliances can cause great influence, the electric appliances can be set as user priority electric appliances, and the electric appliances can operate preferentially all the time. For example, when the variable frequency washing machine cannot normally wash due to variable frequency operation or suspension of operation, a user can set the variable frequency to be an appliance with a user priority, the appliance has the highest priority, and the cloud platform never controls the variable frequency operation and suspension of the appliance.
Further, it is preferable that the use priority level of the user-prioritized appliance > the use priority level of one type of appliance only within the time range set by the user.
Specifically, the user can set one or more of the first-class electric appliances and the second-class electric appliances as user priority electric appliances, and the priority usage level of the electric appliances is greater than that of the first-class electric appliances only in a specific time, and the electric appliances perform the frequency reduction operation according to the priority levels of the first-class electric appliances and the second-class electric appliances outside the specific time range. For example, a user sets the electric water heater as a user priority appliance during 20:00-23:00 nights, and the electric water heater is preferentially operated in the time period so as to meet the bathing requirements of the family. When this time period is exceeded, the water heater acts as a class ii appliance, and when the household circuit power is overloaded, the water heater may be down-rated.
Further preferably, when the total power of household appliances in use in a household is greater than the rated power, the cloud platform controls one or more variable frequency appliances in the two types of appliances to perform frequency reduction operation, and when all the variable frequency appliances in the two types of appliances do not meet the condition after frequency reduction, the cloud platform controls one or more appliances in the two types of appliances to suspend use.
Specifically, as shown in the control flowchart of fig. 1, when a user priority electrical appliance, a first type electrical appliance, and a second type electrical appliance are simultaneously used in a home circuit and a line power overload is caused, that is, the total power of the home electrical appliance is greater than the rated power of the home circuit, the cloud platform controls one of the two types of electrical appliances to perform frequency conversion operation, and when one of the two types of electrical appliances does not satisfy the power requirement of the home circuit after the frequency conversion is reduced, the cloud platform continues to control the other two types of electrical appliances to perform frequency conversion operation. And when all the second-class electric appliances do not meet the power requirement of the household line after the frequency reduction work, controlling one or more electric appliances in the second-class electric appliances to suspend to use until the power consumption requirement of the household line is met. Once the electrical appliance which is in the frequency reduction operation or is suspended meets the power requirement of the household line, other electrical appliances are not controlled to be in the frequency reduction operation or to be suspended. For example: the electric appliances used in the family such as electric cookers, hot water kettles, washing machines, variable frequency air conditioners, refrigerators and variable frequency water heaters work and reach the maximum value allowed by the power of the family line. At present, an electromagnetic oven is needed to be used, which belongs to a first-priority household appliance, and at least one variable frequency appliance in two types of appliances is controlled to work in a variable frequency mode firstly so as to release power to a newly-added first type of appliance. For example, the power required by the induction cooker is 1200W, at least one electric appliance is selected from two types of electric appliances for frequency conversion, for example, one or two of a frequency conversion water heater and a frequency conversion air conditioner are controlled to perform frequency conversion operation, if the frequency conversion operation of the two types of frequency conversion electric appliances still does not meet the power consumption requirement of a household line, one or two of the frequency conversion water heater and the frequency conversion air conditioner are controlled to pause operation until the power requirement of the household line is met. If one of the two types of electric appliances is controlled to carry out frequency reduction operation, the power requirement of the newly added electric appliance can be met, and the frequency reduction operation is not carried out on the other two types of electric appliances. For example, the power requirement of a newly added induction cooker can be met by reducing the refrigerating power of an air conditioner, and the service power of a water heater is not reduced any more.
Further preferably, the cloud platform controls one or more appliances of the second type of appliances to work in a frequency reduction mode or suspend using according to a preset appliance sequence.
Specifically, as shown in fig. 2, when the operation of multiple appliances in the second category of appliances is suspended, the cloud platform performs down-conversion or suspension according to a specific sequence. The specific sequence can be set by the cloud platform according to the use scene or the use time, for example, in a 19:00-23:00 time period, two types of electric appliances in use comprise a variable frequency air conditioner and a variable frequency water heater, and the cloud platform selects to preferably control the variable frequency air conditioner to work downwards or pause work considering that a user has bathing requirements in the time period. Meanwhile, the pause sequence of the appliances can be set by the user, for example, the frequency reduction or pause sequence of the two appliances can be arranged according to the sequence in fig. 3. When the second type of electric appliances need to be paused, the pause is sequentially a disinfection cabinet, a dish washer, a washing machine, an air conditioner, a refrigerator and a water heater.
Further preferably, when the newly added household appliance is used and the cloud platform needs to control one or more of the two types of appliances, the appliances with the frequency reduction power larger than or equal to the use power of the newly added appliance are controlled to perform frequency reduction operation preferentially.
Specifically, when a newly added household appliance is used in a home line, the home line is overloaded, and three types of appliances need to be suspended, the cloud platform preferentially selects an appliance with the frequency reduction use power larger than or equal to the use power of the newly added appliance. For example, when an induction cooker is additionally used, the power of the induction cooker is 1200W, the frequency reduction use power of a frequency reduction air conditioner in the second type of electrical appliances is 1200W, and the frequency reduction use power of the other second type of electrical appliances in use is lower than 1200W, the cloud platform preferentially selects to control the frequency reduction operation of the air conditioner, so that the normal operation of the electrical appliances as much as possible is ensured.
It is further preferable that, when the total power of the household appliances in use is less than the rated power, the difference between the rated power and the total power of the household appliances in use is compared with the down-converted power of the household appliances which have been down-converted in use, respectively, and when the down-converted power of a certain household appliance is less than or equal to the difference, the household appliance recovers the use frequency.
Specifically, when the user controls one or more appliances to be turned off, the total power of the household appliances in use is less than the rated power, and the cloud platform can select one or more appliances which are used in a frequency-reducing mode to recover the use frequency. The principle of the recovery use is as follows: the difference value between the rated power of the household line and the total power of the household appliances in use is compared with one or more appliances suspended from use respectively, and when the use power of a certain household appliance is less than or equal to the difference value, the use frequency of the household appliance is recovered. For example, after cooking, the user turns off the induction cooker and the range hood, the difference between the rated power of the household line and the total power of the household appliances in use is 1200W, and if the appliances in the prior frequency reduction work are an air conditioner and a water heater, the frequency reduction power of the air conditioner is 1200W, and the water heater is 2000W, the cloud platform controls the air conditioner to recover the use frequency.
It is further preferred that the differences between the nominal power and the total power of the household appliance in use are compared in a sequence with the power in use of the household appliance that has been down-converted, the comparison sequence being opposite to the sequence in which the household appliance is down-converted.
Specifically, when the electrical appliances used in the frequency reduction mode have multiple electrical appliances, for example, the electrical appliances suspended for use have a washing machine, an air conditioner and a water heater, and the frequency reduction work sequence of the three electrical appliances is air conditioner → water heater → washing machine, when a certain power is released from the home line, the cloud platform firstly compares the frequency reduction power of the washing machine with the difference value between the rated power of the home line and the total power used, and if the frequency reduction power of the washing machine is greater than the difference value, then compares the frequency reduction power of the water heater and the air conditioner with the difference value in sequence. If the down-conversion power of the washing machine is less than or equal to the difference, the washing machine is controlled to recover the use frequency.
Example two
The embodiment provides a control method based on an internet of things household appliance, which is a control flow chart shown in fig. 1 and includes the following steps:
s1, starting a cloud platform, and connecting the household appliance with the cloud platform in a communication manner;
s2, the cloud platform collects data information of the household appliances connected with the cloud platform;
s3, the cloud platform judges whether the total power of the household appliances in use is larger than the rated total power of the household line, if so, the operation enters S4, and if not, the operation returns to S2;
s4, the cloud platform controls the user to select the electric appliances of the priority class, one electric appliance works normally, and the second electric appliance works in a frequency reduction mode according to a preset sequence;
s5, the cloud platform judges whether the total power of the household appliances in use is larger than the rated total power of the household line, if so, the operation enters S6, and if not, the operation returns to S2;
and S6, the cloud platform controls the second type of electric appliances to pause according to a preset sequence, and returns to S2.
Further, it may be preferred that different categories of appliances are automatically classified by the cloud platform according to the type of the home appliance, and/or by the user according to their own needs.
Specifically, the cloud platform collects data of each high-power appliance of the connected household appliances by using technologies such as internet, wireless communication and the like, and automatically classifies the household appliances according to types of the household appliances, for example, the appliances which affect results when the household appliances are stopped in short periods in midway, such as an electric cooker, an induction cooker, a hot water kettle, a range hood and the like, are classified into a type of appliances, and the priority of the type of appliances is highest. The general electric appliances with the effect influenced by the pause of the electric appliances such as washing machines, dish washing machines, disinfection cabinets, air conditioners, refrigerators, energy storage water heaters and the like in short term are divided into two types of electric appliances, and the electric appliances are in suboptimal priority.
And/or the user can classify the household appliances connected with the cloud platform according to the self-demand, for example, if the user thinks that the electric cooker, the induction cooker and the washing machine have a great influence when being stopped for a short time, the appliances can be classified into a type of appliances, and the priority of the type of appliances is highest. Electrical appliances such as a hot water kettle, a range hood, an air conditioner, a water heater and the like stop working within a short time, and the electrical appliances are generally classified into two types of electrical appliances, and the electrical appliances are in suboptimal priority.
At least one of the two types of electric appliances is a variable frequency electric appliance, such as a variable frequency air conditioner, a variable frequency refrigerator, a variable frequency washing machine, a variable frequency disinfection cabinet, a variable frequency water heater, and the like. When the total power of household appliances in use in a household exceeds the rated power of a household line, the cloud platform controls at least one variable frequency appliance in the two types of appliances to work in a variable frequency mode.
Further, it may be preferable that the order of suspended use of the appliances of the same category is automatically set by the cloud platform according to a use scene or a use time, and/or is customized by a user.
Specifically, as shown in fig. 2, when the operation of multiple appliances in the second category of appliances is suspended, the cloud platform performs the down-conversion operation or the suspension operation according to a specific sequence. The specific sequence can be set by the cloud platform according to the use scene or the use time, for example, in a 19:00-23:00 time period, two types of electric appliances in use comprise a variable frequency air conditioner and a variable frequency water heater, and the cloud platform selects to preferably control the variable frequency air conditioner to work downwards or pause work considering that a user has bathing requirements in the time period. Meanwhile, the pause sequence of the appliances can be set by the user, for example, the frequency reduction or pause sequence of the two appliances can be arranged according to the sequence in fig. 3. When the second type of electric appliances need to be paused, the pause is sequentially a disinfection cabinet, a dish washer, a washing machine, an air conditioner, a refrigerator and a water heater.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
