In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
According to the embodiment of the invention, the current operation stage is obtained, if the operation stage comprises air supply operation, the air supply operation information is determined, and the operation of the fan module and the heating model is controlled based on the air supply operation information, so that cold air is conveyed to the cavity in the cold air starting period, and hot air is conveyed to the cavity in the hot air starting period, the purpose of alternately conveying the cold air and the hot air is realized, a better drying effect is achieved, and the problems that in the existing dishwasher control technology, due to the fact that the air temperature of the air supply operation is low, water vapor in the washing cavity is easy to condense and is attached to the surface of tableware, the cavity environment is still in a humid state, the drying effect is reduced, and bacteria are easy to breed are solved.
In the embodiment of the invention, the execution subject of the process is a dishwasher. The dishwasher is provided with a data processing module, processes information fed back by each sensor or data acquisition device through the data processing module, automatically executes disinfection operation, and the data processing module can be a microprocessor such as a single chip microcomputer. Fig. 1 shows a flowchart of an implementation of a method for controlling a fan according to a first embodiment of the present invention, which is detailed as follows:
in S101, a current operation stage of the dishwasher is acquired.
In this embodiment, the dishwasher may be provided with an operation stage detection period, in which case the dishwasher may acquire an operation stage of the dishwasher at the detection time based on the operation stage detection period interval. Of course, the dishwasher may also be provided with a trigger condition, for example, if it is detected that a certain operation phase is executed and the next operation phase is ready to enter, the operation of S101 may be triggered, so as to determine whether there is an air supply operation in the operation included in the next operation phase, or, when the dishwasher receives an operation instruction initiated by a user, the dishwasher needs to switch the operation phase to an operation corresponding to the operation instruction, so the operation of S101 may also be triggered at this time.
In this embodiment, the dishwasher may automatically perform a washing operation on the dishes according to a preset washing flow and a drying operation after the washing operation, and the operation process includes a plurality of different operation stages, such as a pre-washing stage, a strong washing stage, a drying stage, and a disinfecting stage, and the dishwasher determines the operation stage currently being executed when it is determined that the current water inlet trigger condition is satisfied.
Optionally, in this embodiment, when the dishwasher is started, the operation flow and the total operation time of the operation may be determined according to the operation mode selected by the user, if the preset operation phase detection condition of the dishwasher is met, the operated time is obtained, the operation schedule is determined based on the operated time and the total cleaning time, and the operation phase currently being executed by the dishwasher is determined according to the operation flow and the operation schedule.
In this embodiment, the dishwasher may determine an operation list included in the operation phase according to the operation phase, and determine whether the operation list includes an air supply operation. If the operation list is detected to contain the air supply operation, executing the operation of S102; on the contrary, if the operation list does not include the air blowing operation, the corresponding cleaning operation is executed according to the trigger time of each operation content.
In S102, if the operation stage comprises air supply operation, determining fan operation information associated with the operation stage; the fan operation information comprises a hot air starting period and a cold air starting period.
In this embodiment, after the operation phase of the dishwasher is determined, the dishwasher determines the operation content included in the operation phase by acquiring the operation list associated with the operation phase, and if the operation phase needs to perform an air supply operation, the dishwasher may determine the fan operation information corresponding to the operation phase. In order to improve the accuracy of the air supply operation, the dish washing machine can be established with corresponding relations between different operation stages and fan operation information. For example, if the tableware needs to be initially dried after being washed, the time of the corresponding air supply operation is long due to the fact that the humidity in the cavity is high, and at this time, corresponding fan operation information can be configured for the washing stage; in the tableware storage stage, only the air in the cavity needs to be updated at the moment, namely, the air convection is realized, so that the cleanliness of the tableware in the cavity is improved, the corresponding air supply operation time is short, and at the moment, the operation information of another fan can be configured for the disinfection stage. Therefore, the dishwasher can configure the fan operation information corresponding to the operation characteristics of different operation stages.
Optionally, in this embodiment, the dishwasher may determine an operation duration of the air supply operation according to the predicted humidity value of each operation stage, perform type division on the operation duration, divide the operation duration into a hot air supply duration and a cold air supply duration, determine the number of cycles based on the operation duration, and perform cycle division on the hot air supply duration and the cold air supply duration respectively to obtain a hot air start cycle and a cold air start cycle. Of course, when detecting that the current operation stage includes air supply operation, the dishwasher can also acquire the humidity value in the current cavity through the humidity sensor, determine the operation duration of the air supply operation according to the actually acquired humidity value, execute the operation and generate fan operation information.
In this embodiment, the fan operation information includes a hot air start cycle and a cold air start cycle, and the hot air start cycle and the cold air start cycle alternate with each other. Namely, the cycle type adjacent to the hot air starting cycle is the cold air starting cycle, and the cycle type adjacent to the cold air starting cycle is the hot air starting cycle, so that the fan can alternately blow out hot air and cold air, and a better drying effect is achieved.
In S103, if it is detected that the hot air starting period is reached, a heating module and a blower module are started to deliver hot air at a preset first temperature to the cavity of the dishwasher.
In this embodiment, dish washer is when detecting to get into hot-blast start cycle, then indicate to need to carry in the cavity hot-blastly, based on this, dish washer can start heating module, this heating module can be for the heating plate, thereby can heat the air of within range through heating module, promote the first temperature with the air from the normal atmospheric temperature, and start the fan module and carry the hot-blast that has arrived first temperature in to the cavity, thereby can vaporize the water in the cavity, and outside discharging the cavity through the air outlet, reduce the humidity in the cavity.
Preferably, the dishwasher can acquire the initial temperature in the cavity when detecting that the next starting period is the hot air starting period, calculate the heating time length according to the difference between the initial temperature and the first temperature, and perform preheating operation through the heating module before entering the hot air starting period based on the heating time length, so that hot air can be rapidly conveyed to the cavity when the hot air starting period is reached.
In step S104, if it is detected that the cold air start cycle is reached, closing the heating module and starting the fan module to deliver cold air at a preset second temperature to the cavity; the first temperature is greater than the second temperature.
In this embodiment, when the dishwasher detects that the cold air enters the start cycle, it indicates that the cold air needs to be conveyed in the cavity to reduce the temperature in the cavity, so that the water vapor in the cavity is condensed to reduce the humidity of the air. Based on this, if the heating module in the dish washer is in the on-state, then need close the heating module, avoid the heating module to heat the air of within range to reduce the temperature value second temperature of air in the cavity, and start the fan module and to carry the cold wind that has arrived the second temperature in the cavity, and open the air outlet and avoid the atmospheric pressure in the cavity too big and lead to the water to spill over.
As can be seen from the above, in the method for controlling a fan provided in the embodiment of the present invention, by acquiring the current operation stage, if the operation stage includes an air supply operation, determining air supply operation information, and controlling the operation of the fan module and the heating model based on the air supply operation information, cold air is delivered to the cavity in a cold air start cycle, and hot air is delivered to the cavity in a hot air start cycle, so that the purpose of alternately delivering the cold air and the hot air is achieved, and a better drying effect is achieved. Compared with the control technology of the existing dish washing machine, the invention not only conveys cold air to the cavity in the drying stage, but alternatively conveys the cold air and the hot air, can re-vaporize the water body attached to the inner wall of the cavity and the tableware in the hot air conveying stage, discharges the water body out of the cavity through the air outlet, reduces the temperature in the cavity by conveying the cold air, avoids the overheating of the heating plate and the overheating damage of the tableware caused by conveying the hot air for a long time, balances the drying effect and the equipment safety, and improves the use experience of users.
Fig. 2 shows a flowchart of a specific implementation of a method S104 for controlling a fan according to a second embodiment of the present invention. Referring to fig. 2, with respect to the embodiment shown in fig. 1, a method S104 for controlling a fan provided in this embodiment includes: s1041 to S1043, which are detailed as follows:
further, if it is detected that the cold air starting period is reached, the heating module is closed and the fan module is started to convey cold air at a preset second temperature to the cavity, including:
in S1041, a surface temperature of the heating module is acquired.
In this embodiment, the dish washer is before carrying cold wind, because heating module surface temperature is higher and the cavity internal temperature is higher, if wait for heating module automatic cooling then need longer time to it is long when the air supply of dish washer has been prolonged, has reduced air supply efficiency. Based on this, the dish washer is still built-in to have the condensation module, can carry out cooling operation to heating module through the condensation module. For example, this condensation module can be the condenser pipe, and this condenser pipe pours into there is mobile water, constantly takes away the temperature on heating module surface through the flow of water, realizes the purpose of cooling. Of course, this condensation module can also include the condensation material, adsorbs on the surface of heating module through the condensation material to absorb the temperature on heating module surface, reach refrigerated effect.
In this embodiment, the dishwasher may be provided with a temperature sensor on the surface of the heating module, and the temperature of the surface of the heating module may be acquired by the temperature sensor. It should be noted that the operation of S101 may be performed when entering the cool-air start cycle, and the dishwasher may be configured with a pre-cooling time, and perform the operations of S1041 to S1043 at a first time before entering the cool-air start cycle, where a time difference between the first time and a start time of the cool-air start cycle is equal to the pre-cooling time.
In S1042, if the surface temperature is greater than a preset temperature threshold, a temperature difference between the surface temperature and the second temperature is calculated, and a cooling duration is determined according to the temperature difference.
In this embodiment, if the dishwasher detects that the surface temperature of the heating module is greater than the preset temperature threshold, it indicates that the surface temperature of the heating module is too high, and if the blower is started at this time, the heated air is conveyed in the cavity, so that the heating module needs to be cooled by the condensing module; on the contrary, if the detected surface temperature of the heating module is smaller than or equal to the preset temperature threshold value, the surface temperature of the heating module is in a normal state, and at the moment, the surface temperature of the heating module can be gradually reduced to a second temperature through the air blowing operation of the fan, so that cold air can be conveyed into the cavity.
In this embodiment, the dishwasher may obtain a cooling curve according to the module type of the condensing module, and introduce the cooling curve according to the temperature difference between the surface temperature and the second temperature, so as to calculate the corresponding cooling time period. Specifically, if the temperature difference is larger, the corresponding cooling time length is longer; conversely, if the temperature difference is smaller, the corresponding cooling time period is shorter.
In S1043, cooling the heating module by the condensing module based on the cooling duration, and starting the blower module to deliver cold air at a preset second temperature to the cavity.
In this embodiment, the dish washer can start the condensation module, and the condensation material through the condensation module carries out cooling operation to the heating module, and the length of operation of this cooling operation is long for the cooling that above-mentioned calculation obtained promptly to make the surface temperature of heating module reduce to preset temperature value, start the fan again this moment then can carry the cold wind of second temperature to the cavity.
In the embodiment of the invention, the surface temperature of the heating module is detected before the cold air is conveyed, and the surface of the heating module is cooled through the condensing module, so that the cold and hot air conversion efficiency can be improved, and the drying effect is improved.
Fig. 3 shows a flowchart of a specific implementation of a method S103 for controlling a fan according to a third embodiment of the present invention. Referring to fig. 3, with respect to the embodiment shown in fig. 1, a method S103 for controlling a fan provided in this embodiment includes: s1031 to S1032 are specifically described as follows:
further, if it is detected that the hot air starting period is reached, a heating module and a fan module are started to convey hot air at a preset first temperature to a cavity of the dishwasher, including:
and in S1031, receiving an operation waveform diagram fed back by the fan module.
In this embodiment, the dishwasher may further recognize an abnormal state in a hot wind start cycle, and the specific implementation process is as follows: the built-in fan module of the dishwasher can generate an operation waveform in the normal operation process and feed back the operation waveform to the dishwasher. When the dishwasher receives the running waveform chart, the dishwasher is indicated to be in a normal running state; otherwise, if the dishwasher does not receive the operation waveform diagram fed back by the fan module and the time period belongs to the fan starting period, the operation of S1032 is executed.
In S1032, if the operation waveform map is not received in the hot air start cycle, generating device abnormality information, and turning off the heating module and the fan module.
In this embodiment, if the dish washer does not receive the operation oscillogram in hot-blast start cycle, then probably the fan module is unusual, unable normal start, if continue to start heating module this moment, because do not have the fan module to heat dissipation on heating module surface, lead to surface temperature too high easily and damage equipment and tableware, consequently, the dish washer will close heating module and fan module, and generate an equipment abnormal information to inform the user and handle the abnormal conditions.
In the embodiment of the invention, the abnormal condition is detected by acquiring the running oscillogram fed back by the fan module, the damage to equipment and tableware caused by continuous heating of the heating module under the condition that the fan cannot run normally can be avoided, and the running safety of the equipment is improved.
Fig. 4 shows a flowchart of a specific implementation S103 of a method for controlling a fan according to a fourth embodiment of the present invention. Referring to fig. 4, with respect to the embodiment described in fig. 1-3, the method S102 for controlling a fan provided in this embodiment includes: s1033 to S1035 are specifically described as follows:
further, if it is detected that the hot air starting period is reached, a heating module and a fan module are started to convey hot air at a preset first temperature to a cavity of the dishwasher, including:
in S1033, the heating temperatures of the heating modules are acquired at preset interval periods, and an actual temperature-increasing curve of the heating modules is generated based on a plurality of the heating temperatures.
In this embodiment, the dishwasher may perform abnormality recognition on the heating module in addition to abnormality recognition on the fan module. In this case, the dishwasher may acquire the surface temperature of the heating module, i.e., the above-mentioned heating temperature, a plurality of times at a preset time interval, and after acquiring one heating temperature, may create a coordinate point of the heating temperature on a preset coordinate axis based on a value of the heating temperature, the coordinate point being associated with the acquisition time and the value of the heating temperature. The dishwasher can construct an actual heating curve of the heating module in the hot air starting period according to the heating temperatures acquired in the plurality of acquisition periods.
In S1034, an error area between the actual temperature-increasing curve and a standard temperature-increasing curve of the heating module is calculated.
In this embodiment, after the dishwasher establishes the actual temperature-raising curve, the standard temperature-raising curve of the heating module may be marked in the coordinate axis, so that the difference region between the two temperature-raising curves can be determined, and the difference region is integrated, so that the area corresponding to the difference region, that is, the error area, may be calculated. If the error area is larger, the larger the deviation between the actual temperature-rising curve and the standard temperature-rising curve is, the abnormal state is possibly caused; conversely, if the error area is smaller, it indicates that the degree of difference between the heating module and the rated operation state is small, and the heating module is in a normal state.
In S1035, if the error area is larger than a preset abnormality threshold, the heating module is identified as abnormal, and module abnormality information about the heating module is generated.
In this embodiment, if it is detected that the error area is greater than the abnormal threshold, it indicates that the heating module has a large difference from the rated operation state, and the temperature is too high due to too fast rising or too slow rising, and the drying requirement cannot be met, and at this time, the heating module is identified as an abnormal module, and module abnormal information of the heating module is generated, so that the user performs abnormal processing.
In the embodiment of the invention, whether the heating module is abnormal or not can be identified by acquiring a plurality of heating temperatures and constructing the actual heating curve of the heating module, so that the abnormal identification of the heating module can be realized, and the safety of equipment is improved.
