It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
According to the embodiment of the invention, before the washing equipment carries out hot air supply, the corresponding heating start time can be determined according to the determined hot air supply trigger time, and the heating start time is earlier than the hot air supply trigger time and is a preset heating time length away from the hot air supply trigger time; then the washing equipment can start the heating part arranged at the air outlet of the fan at the heating start time, heat the heating part to a preset target temperature value in advance, when the hot air supply trigger time is reached, the air around the heating part is heated to a specified temperature, when hot air is conveyed into the washing cavity at the moment, the air around the heating part is heated to the target temperature, and the air output into the washing cavity at the moment is necessarily hot air, so that the aim of accurately conveying the hot air can be fulfilled, the control technology of air supply is solved, the problems that when the hot air is conveyed into the washing cavity, the hot air is firstly cooled and then heated, the drying effect is poor, and the control accuracy of the washing equipment is low are solved.
In an embodiment of the present invention, the execution subject of the flow is a washing apparatus including, but not limited to: the dishwasher and the baby bottle washing machine, in particular, the washing apparatus may have a washing function of laundry in addition to washing tableware. The washing equipment is provided with a data processing module, the operation of the washing equipment is controlled through the data processing module, the washing equipment further comprises a fan used for blowing air in a washing cavity and a heating component arranged at an air outlet of the fan, so that hot air is conveyed in the washing cavity, the purposes of drying, disinfecting and the like of tableware in the washing cavity are achieved, and an exemplary schematic diagram of the structure of the washing cavity provided by an embodiment of the application is shown in fig. 1. Referring to fig. 1, the washing chamber includes a chamber body 01 for placing tableware, a fan 02 and a heating component 03, wherein the fan 02 can be disposed in a designated area of an inner wall of the chamber body 01 to convey external wind into the washing chamber, and the heating component 03 is disposed at an air outlet of the fan 02, so that a temperature around the air outlet can be raised to convey hot wind to the chamber body 01.
Fig. 2 shows a flowchart of an implementation of a method for controlling air supply according to a first embodiment of the present invention, which is described in detail below:
In S201, determining a heating start time corresponding to a thermal air supply trigger time based on a preset thermal air supply trigger time; the heating start time is earlier than the hot air supply trigger time, and the difference between the heating start time and the air supply trigger time is heating duration.
In this embodiment, the washing device is configured with a hot air supply trigger time, and in particular, the hot air supply trigger time may be specifically used for a trigger time of delivering hot air to the washing chamber, and when the hot air supply trigger time is detected to be satisfied, it indicates that a hot air supply operation is required, and a fan is required to be started to deliver hot air to the washing chamber. When the washing equipment is started to operate, at least one hot air supply trigger time for conveying hot air can be determined according to a preset cleaning flow. Of course, if one cleaning process needs to deliver hot air into the washing chamber multiple times, in this case, the number of the hot air supply trigger times may be multiple, and the washing device may be configured with the corresponding heating start times for different hot air supply trigger times, that is, the number of the heating start times may be matched with the number of the hot air supply trigger times.
In one possible implementation, the washing device may determine the type of operation of the specific preamble operation before determining the heating start time corresponding to the hot blast trigger time. If the preface operation of the hot air supply trigger time is the hot air supply operation, namely, the washing equipment continuously executes the hot air supply operation twice, in this case, when the subsequent hot air supply operation is executed, the heating component is already at a higher temperature, and the temperature of the air around the heating component is also raised, at this time, the heating component does not need to be started in advance, and the heating component can be restarted when the fan is started. Therefore, if the operation type of the preamble operation of the hot air supply trigger time is the hot air supply operation, the hot air supply trigger time is the heating start time; if the operation type of the preamble operation of the hot air supply trigger time is a non-hot air supply operation, the time of the heating duration preset before the hot air supply trigger time is taken as the heating start time, namely, the time difference between the heating start time and the hot air supply trigger time is the heating duration, and the heating start time is earlier than the hot air supply trigger time.
In this embodiment, the heating duration may be a preset value, that is, the differences between all the hot air supply trigger moments and the heating start moments are the same, and are all heating durations with the same value; alternatively, the heating duration may be changed accordingly, depending on the actual environmental factors, for example, the lower the environmental temperature is, the longer the corresponding heating duration is; the higher the ambient temperature, the shorter the corresponding heating duration.
In one possible implementation, the heating unit may be configured with different heating powers, and the washing apparatus may determine the heating power corresponding to the heating unit according to the current operation mode, and set the heating duration based on the heating power. For example, when the washing device is in the energy-saving mode, the corresponding heating power is smaller, and the corresponding heating duration is longer; on the contrary, when the washing equipment is in the high-performance mode, the corresponding heating power is larger, and the corresponding heating duration is shorter.
In one possible implementation manner, the washing device may obtain a current ambient temperature, where the ambient temperature may be an outdoor temperature, for example, a thermometer may be configured on an outer frame of the washing device, and the current outdoor temperature is determined by reading a value of the thermometer, and a heating duration corresponding to the current outdoor temperature is determined according to the outdoor temperature.
It should be noted that, the operation in S201 may be performed when the washing device is started, that is, when the corresponding washing process needs to be performed, the washing device may determine the hot air supply trigger time when the hot air supply operation needs to be performed, and at this time, the washing device may determine the heating start time corresponding to each hot air supply trigger time.
In S202, if the heating start time is reached, a heating component placed at an air outlet of the fan is started, so that the heating component is heated to a preset target temperature value.
In this embodiment, after determining the heating start time and the hot air supply trigger time, the washing device may numerically control the washing device to perform corresponding operations according to the two times. If the current moment is detected to reach the determined heating starting moment, a heating component arranged at the air outlet of the fan can be started, and the heating component can perform heating operation after being started until the temperature of the heating component is raised to a preset target temperature value. After the heating component is heated to the target temperature value, the heating component is kept at the preset target temperature value, and the heating is not continued, so that the air around the heating component is also lifted to the preset target temperature value.
In one possible implementation manner, the washing device may obtain a temperature value corresponding to the heating element when the hot air supply trigger time is reached, and if the temperature value is within a floating range corresponding to the target temperature value, identify that the heating element is in a normal working state; conversely, if the temperature value of the heating member at the time of reaching the hot blast trigger is outside the above-described floating range, temperature abnormality information is generated. The washing apparatus may transmit the temperature abnormality information to a terminal of a corresponding user of the washing apparatus or a terminal of a maintenance person so as to cope with the abnormality.
In one possible implementation manner, after the washing device generates the temperature abnormality information, the operation power of the heating component of the washing device can be adjusted according to the temperature abnormality information so as to repair the abnormality. For example, if the temperature value of the heating member at the time of reaching the hot blast trigger is lower than the above-described floating range, the output power of the heating member may be increased; conversely, if the temperature value of the heating member at the time when the hot blast trigger is reached is higher than the above-described float division, the output power of the heating member can be reduced.
In S203, when the hot air supply trigger time is reached, the blower is started so that the air supplied by the blower passes through the heating means which is heated to the target temperature value, and hot air is supplied to the dishes in the washing chamber.
In this embodiment, after the heating start time, the washing device reaches the corresponding hot air supply trigger time after the heating time, at this time, the washing device may start the blower to blow air into the washing cavity, and because the heating component is disposed at the air outlet of the blower, the output air will be heated by the heating component and then be conveyed into the washing cavity, so that the air conveyed into the washing cavity is hot air.
It can be seen from the foregoing that, in the control method for air supply provided by the embodiment of the present invention, before hot air supply is performed by the washing device, the corresponding heating start time can be determined according to the determined hot air supply trigger time, where the heating start time is earlier than the hot air supply trigger time and is a preset heating duration from the hot air supply trigger time; then the washing equipment can start the heating part arranged at the air outlet of the fan at the heating start time, heat the heating part to a preset target temperature value in advance, when the hot air supply trigger time is reached, the air around the heating part is heated to the designated temperature, and when hot air is conveyed into the washing cavity at the moment, the air around the heating part is heated to the target temperature, and the air output into the washing cavity at the moment is necessarily hot air, so that the aim of accurately conveying the hot air can be fulfilled. Compared with the existing control technology of air supply, the heating component is started not when the air supply is needed, but before the hot air supply triggering time, the heating component is started for a certain time, so that the temperature of the air around the heating component is raised when the hot air supply is performed, the air which is conveyed into the washing cavity is hot air, the condition that the conveyed air is firstly cooled and then heated when the hot air supply is needed is avoided, the accuracy of the hot air supply process is improved, and the drying effect is improved.
Fig. 3 is a flowchart showing a specific implementation of a method for controlling air supply according to a second embodiment of the present invention. Referring to fig. 3, with respect to the embodiment shown in fig. 2, in the method for controlling air supply provided in this embodiment, before determining the heating start time corresponding to the thermal air supply trigger time based on the preset thermal air supply trigger time, the method further includes: s301 to S302 are specifically described below:
further, before the heating start time corresponding to the hot air supply trigger time is determined based on the preset hot air supply trigger time, the method further includes:
at S301, at the end of the rinsing process, a first temperature value in the washing chamber is acquired.
In this embodiment, the above-mentioned drying operation for conveying hot air is performed after the rinsing process is finished, and before drying, the humidity in the washing chamber is high, and a period of time is required to be kept still, so that the water vapor in the washing chamber can be condensed to the surface of the tableware, thereby being more beneficial to the subsequent drying process. Thus, at the end of the rinsing process, the time period for which the resting is required may be first determined, and the time period for which the resting is related to the temperature in the washing chamber, and thus, the temperature in the chamber at the completion of the rinsing process, i.e., the above-described first temperature value, may be measured by a thermometer placed in the washing chamber.
In S302, a rest period is determined based on the first temperature value, and the hot blast trigger time is determined according to the rest period.
In this embodiment, the washing apparatus may determine the standing time period according to the first temperature value acquired as described above. The manner of determining the standing time length may be: the washing equipment is configured with a preset corresponding relation table of the standing time length and the temperature in the cavity, and after the first temperature value is obtained, the standing time length corresponding to the first temperature value can be determined by inquiring the corresponding relation table. The higher the first temperature value in the cavity is, the longer the corresponding standing time is; conversely, if the first temperature value in the cavity is lower, the corresponding standing time period is shorter.
In one possible implementation, the washing device may also acquire an ambient temperature, and the rest period may be determined according to the ambient temperature and the first temperature. Wherein the relationship between the first temperature value and the rest period is as described above; the washing equipment can determine the standing time by calculating the difference between the ambient temperature and the first temperature value; the smaller the difference value between the two is, the shorter the corresponding standing time is; on the contrary, the larger the difference between the two, the longer the corresponding standing time length.
In this embodiment, after determining the standing duration, the washing device may determine the corresponding hot air supply trigger time according to the standing duration. The hot air supply touch time may specifically be: and the difference value between the hot air supply triggering time and the time when the rinsing process ends is the rest time length.
In one possible implementation, after determining the standing duration, the electronic device may determine a heating duration corresponding to the hot blast trigger time, that is, perform the operation of S201. If the standing time is longer than or equal to the heating time, the heating start time is later than the end time of the rinsing process, and the heating component can be heated at the moment; otherwise, if the standing time is shorter than the heating time, the heating start time is earlier than the end time of the rinsing process, and the heating component does not have a proper time to finish the heating operation.
In this application embodiment, before carrying out hot air supply, can be in the time length of standing in order to make the steam condensation of washing intracavity in predetermineeing, can improve the stoving effect of follow-up stoving operation, improved washing equipment's control accuracy.
Fig. 4 shows a flowchart of a specific implementation of a method S302 for controlling air supply according to a third embodiment of the present invention. Referring to fig. 4, with respect to the embodiment shown in fig. 3, a control method S302 for air supply provided in this embodiment includes S3021 to S3024, which are specifically described below:
further, the determining the standing time based on the first temperature value, and determining the hot air supply trigger time according to the standing time includes
In S3021, a humidity value in a washing chamber and an air flow rate in the washing chamber are acquired.
In this embodiment, the washing apparatus may dynamically adjust the above-described rest period according to the current state in the washing chamber. Wherein the washing apparatus may determine a current humidity value in the washing chamber and an air flow rate in addition to determining the first temperature value in the washing chamber. Because the washing equipment is not in a completely closed state, certain air flows, and therefore, the condensation of the water body in the washing cavity is influenced, the washing equipment can determine the humidity value and the corresponding air flow rate in the washing cavity through components such as a hygrometer, a flowmeter and the like.
In S3022, determining a first cooling factor from the air flow rate; the first cooling factor is calculated in the following manner:
wherein TemptDown 1 Is the first cooling factor; airflowSpd is the air flow rate; baseSpd is a preset reference air flow rate; baseTime is a preset reference cooling coefficient; hermeticLv is the degree of sealing of the wash chamber; alpha is a preset weighting coefficient.
In this embodiment, when the rest period is determined, it may be determined by two coefficients, which are a first cooling factor related to the air flow rate (i.e., affecting the cooling rate) and a second cooling factor related to the temperature difference (i.e., the cooling amplitude), respectively.
In this embodiment, the washing device may introduce the obtained air flow rate into a conversion algorithm of the corresponding first cooling factor, and determine a corresponding cooling speed according to a ratio between the air flow rate and a preset reference flow rate, where it is to be noted that, if the air flow rate is higher, the corresponding cooling speed is faster, so that the corresponding standing duration is shorter, that is, the value of the first cooling factor is smaller; otherwise, if the air flow rate is slower, the corresponding cooling speed is slower, and the corresponding standing time period is longer, namely the value of the first cooling factor is larger.
In S3023, determining a second cooling factor according to the first temperature value and the humidity value; the second cooling factor is calculated in the following way:
wherein, the first cooling factor is the second cooling factor; timeDown is the base cooling coefficient; humidi is the Humidity value; tempt 1 Is the first temperature value; targettemperature is a preset target temperature value.
In this embodiment, the washing apparatus may introduce the first temperature value and the humidity value into the conversion model of the second cooling factor, so that the corresponding second cooling factor can be calculated. Determining a second cooling factor by calculating a difference value between the first temperature value and a target temperature value for cooling, wherein if the difference value between the two temperature values is larger, the corresponding second cooling factor is larger, and the longer the standing time length is calculated by the second cooling factor; otherwise, if the difference between the two temperature values is smaller, the corresponding second cooling factor is smaller, and the standing time obtained through calculation of the second cooling factor is shorter. Wherein, humidity value also has certain influence to cooling rate.
In S3024, the rest period is determined according to the first cooling factor and the second cooling factor.
In this embodiment, after the two factors are determined, the washing apparatus may calculate the corresponding rest time period by using the two factors.
In the embodiment of the application, by acquiring a plurality of cooling factors for determining the standing time, the time required for standing the water vapor in the washing cavity can be considered from a plurality of dimensions, the accuracy of the standing time is improved, and the drying effect of the subsequent drying operation is improved.
Fig. 5 shows a flowchart of a specific implementation of a method S201 for controlling air supply according to a fourth embodiment of the present invention. Referring to fig. 5, with respect to the embodiment shown in fig. 2, a method S201 for controlling air supply according to the present embodiment includes: s2011 to S2015 are specifically described as follows:
in S2011, a temperature rise curve of the heating member and a material type of a material for fixing the heating member are acquired.
In this embodiment, the washing apparatus may dynamically adjust the heating time period, based on which two parameters, i.e., a target temperature value to which the heating element needs to be raised and a time required to raise to the target temperature value, need to be determined. The target temperature value to be raised is related to the type of material used to fix the heating element, and the time required to raise the heating element to the target temperature is related to the temperature rise profile of the heating element, so that the washing apparatus can acquire the two parameters.
The washing device can determine the information related to each component by inquiring the device model of the washing device, wherein the information comprises the material type of the material for fixing the heating component.
The washing equipment can store the temperature rise curve of the heating component in a local storage unit, and the temperature rise curve is obtained by reading the temperature rise curve through the local storage unit. The temperature rise curve can be acquired and generated in the using process, and can also be preset and obtained when the washing equipment leaves the factory.
Further, as another embodiment of the present application, the following steps may be further included before S2011:
step 1, acquiring a plurality of historical temperatures of the heating component in the starting process at preset acquisition intervals when the heating component is started in a historical manner.
And step 2, generating the temperature rise curve according to a plurality of historical temperatures.
In this embodiment, the washing apparatus may acquire, during the heating process of the heating element by the history, a plurality of history temperatures during the heating process (i.e. the starting process) at preset acquisition intervals, and determine, by using the plurality of history temperatures, a heating rate and a temperature rising trend of the heating element during the heating process, and mark, according to each acquired history temperature, a temperature rising curve corresponding to the heating element.
In one possible implementation manner, the washing device may store an original temperature rise curve of the heating part in advance, mark each historical temperature on a coordinate system where the original temperature rise curve is located, and adjust the original temperature rise curve based on each historical temperature to generate the temperature rise curve.
In S2012, a deformation temperature threshold corresponding to the material type is determined based on a preset material temperature relationship table.
In this embodiment, since the dissolution deformation temperatures corresponding to the different materials are different, when the heating component is heated, in order to ensure that the framing and structure in the washing device cannot be changed due to the high temperature, it is necessary to determine the deformation temperature threshold corresponding to the material for fixing the heating component. The deformation temperature threshold value is determined by querying a preset material temperature relation table, so as to determine the deformation temperature threshold value corresponding to the material type of the material of the fixed heating component.
In S2013, the target temperature value is determined according to the deformation temperature threshold and a preset upper rinsing limit temperature.
