The heat pump type clothes dryer dries clothes through a heat pump system, the clothes dryer can be provided with an NTC temperature sensor to monitor the temperature of the system in real time, and when the temperature of the system is too high, a fan is started to cool; and when the temperature of the system is reduced to be within an acceptable range, the fan is turned off. However, if the NTC temperature sensor fails, the real system temperature cannot be detected in time, and the dryer may not start the fan to cool down in time.
If a fixed start-stop time sequence is adopted (for example, the fan is started to run periodically, and the fan is turned off for 180 seconds after being started for 60 seconds in each period), the fan can also effectively cool the system, but if the fan start-stop time sequence parameters are set unreasonably, the fan can not timely cool the heat pump system, the temperature of an electric device is too high, the service life is influenced, and even clothes can be damaged due to the too high temperature; or the drying temperature cannot be kept in an ideal range due to the overlong starting time of the fan, so that the drying efficiency is reduced.
Fig. 1 is a schematic flow chart of a clothes dryer control method according to an embodiment of the present disclosure. As shown in fig. 1, the method includes at least the following steps.
Step 110: the method comprises the steps of responding to a starting instruction of a drying program, collecting the system temperature of a heat pump system in the clothes dryer, controlling a fan in the clothes dryer to be closed within a first preset time range according to a time sequence control logic, and controlling the fan to run the time sequence control logic in a preset starting and stopping time sequence after the fan is controlled within the first preset time range according to the time sequence control logic.
During the operation of the drying program, the compressor in the heat pump system heats the air in the system to dry the clothes. This application sets up and starts the stoving procedure after the user, and system temperature in the heat pump system begins real-time supervision, at the initial stage of stoving procedure operation, in order to make system temperature rise fast with the stoving clothing, the fan is closed at first preset time within range, stops the chronogenesis operation in order to predetermine opening behind the first preset time within range, avoids the compressor to last the heating to lead to system temperature to rise too fast or high.
The corresponding duration of the first preset time range is set to be T1, in specific implementation, a timer can be adopted to count down T1, and after counting down is finished, the fan is controlled to operate in a preset start-stop time sequence.
Step 120: and if the system temperature is greater than or equal to the first preset temperature, interrupting the sequential control logic and controlling the fan to be continuously started.
The first preset temperature is an intermediate value of a normal operating temperature range of the heat pump system in the drying program operation. When the drying program runs for a period of time, the clothes dryer is possibly influenced by external factors such as filter screen blockage and the like, so that the temperature of the system increases suddenly, and when the temperature of the system is higher than or equal to the first preset temperature, if the fan is continuously controlled to run according to the time sequence control logic, the temperature of the system can further rise, the condition that the temperature of the compressor is too high can be caused, so that the service life of the compressor and clothes are negatively influenced, the time sequence control logic is interrupted, the fan is controlled to be continuously started, and the temperature of the heat pump system is quickly reduced.
Step 130: and if the system temperature is less than or equal to a third preset temperature, controlling the fan to continue to operate from the interrupted part of the sequential control logic, wherein the third preset temperature is lower than the first preset temperature.
The third predetermined temperature is a lowest limit value of a normal operating temperature range of the heat pump system in the drying program operation. When the temperature of the system is less than or equal to the third preset temperature, if the system is continuously controlled to be continuously started, the temperature of the system is further reduced, the efficiency of drying clothes is obviously reduced, and therefore the continuous starting state of the fan is stopped, and the fan is continuously operated from the interruption position of the sequential control logic. When the fan operates according to the sequential control logic, the system temperature can slowly rise, energy consumed by the continuous starting of the fan can be saved, the system temperature is maintained in a certain ideal temperature range, and the drying efficiency is improved.
Step 140: and if the system temperature is greater than or equal to a second preset temperature, performing fault detection on the clothes dryer, and controlling the fan to operate according to control logic matched with a fault detection result, wherein the second preset temperature is higher than the first preset temperature.
The second predetermined temperature is a maximum limit of a normal operating temperature range of the heat pump system during the drying process. The NTC temperature sensor assembled on the heat pump clothes dryer can be damaged or the detection value is abnormal, so that the temperature of the system is measured inaccurately, or the clothes dryer is influenced by external factors such as filter screen blockage, and the temperature of the system is increased suddenly, therefore, when the temperature of the system is more than or equal to the second preset temperature, the fault detection is carried out on the clothes dryer, whether the software and hardware faults occur in the clothes dryer is detected in time, and the operation of the fan is controlled by combining the fault condition of the clothes dryer.
The embodiment of the application controls the fan to run in a sequential control logic mode or continuously open by combining the system temperature of the heat pump system, so that the system temperature is stabilized in a reasonable drying temperature range, and the drying efficiency of the clothes dryer is improved.
In some embodiments of the present application, based on the foregoing scheme, the controlling the fan to operate with a preset start-stop time sequence after a first preset time range includes:
and controlling the fan to periodically operate after the fan is in the first preset time range, and controlling the fan to be turned on for a second preset time period and then turned off for a third preset time period in one period.
It should be noted that the first preset time range, the second preset time period, and the third preset time period are important parameters for controlling the operation of the fan, and may be set in the MCU control software of the clothes dryer. In specific implementation, the optimal parameters can be fitted through experimental data by combining specific working indexes of the heat pump system of the clothes dryer.
In some embodiments of the present application, based on the foregoing solution, the dryer control method further includes:
if the fan operates according to the sequential control logic, a pause instruction of the drying program is received within a first preset time range, interrupting the sequential control logic, responding to a recovery instruction of the drying program, and controlling the fan to continue to operate from the interrupted part of the sequential control logic;
and if the pause instruction of the drying program is received after the first preset time range when the fan operates according to the sequential control logic, responding to the recovery instruction of the drying program, and controlling the fan to operate again according to the preset start-stop sequential.
In the present application, the drying program is suspended in stages, and if the drying program is suspended in a stage where the blower is not operated (i.e., within the first preset time range), the countdown to T1 is interrupted, and after the drying program resumes operation, the countdown to T1 is continued. After the drying program is suspended, the system temperature is at a lower level at the moment, and the system temperature is gradually reduced, so that after the drying program resumes operation, the fan is continuously controlled to be turned off until the T1 countdown is finished, so that the system temperature is rapidly increased to dry the clothes, and the drying efficiency is improved.
At the stage (namely after the first preset time range) that the fan started and stopped the chronogenesis operation according to presetting, drying program is suspended, and system temperature can reduce gradually this moment, still is in the intermediate level, closes the fan and can cause system temperature to rise at the excessive speed, consequently waits drying program to resume the operation back, stops the chronogenesis operation with presetting again, avoids system temperature to rise at the excessive speed, causes negative effects to compressor, clothing.
In some embodiments of the present application, based on the foregoing solution, if the system temperature is greater than or equal to a second preset temperature, performing fault detection on the clothes dryer, and controlling the fan to operate according to a control logic matched with a fault detection result, including:
if the system temperature is greater than or equal to the second preset temperature and the clothes dryer breaks down, terminating the drying program and closing the load of the clothes dryer;
and if the system temperature is greater than or equal to the second preset temperature and the clothes dryer is not in fault, controlling the fan to continue to operate from the interrupted part of the sequential control logic.
The temperature sensor is in fault, so that the acquired system temperature is inaccurate, or the system temperature is suddenly increased due to external force factors such as blockage of a filter screen of the clothes dryer, and when the system temperature of the clothes dryer exceeds a normal range, the clothes dryer can judge whether the current complete machine system reaches a fault alarm condition. If the plurality of clothes dryers reach the alarm condition, displaying fault alarm on a display panel of the clothes dryer or a client corresponding to the clothes dryer so as to inform a user, closing all loads (including a motor, a compressor, a fan and the like) and preventing the compressor from being damaged due to overhigh temperature or damaging dried clothes; and if the plurality of clothes machines do not reach the alarm condition, controlling the fan to be closed and controlling the fan to continue to operate from the interrupted part of the sequential control logic.
In some embodiments of the present application, based on the foregoing solution, the method further comprises:
and if the suspension instruction of the drying program is received when the fan is continuously started, responding to the recovery instruction of the drying program, and controlling the fan to continuously start until the system temperature is less than or equal to a third preset temperature.
When the fan is continuously started (namely the system temperature is between the first preset temperature and the second preset temperature), a pause instruction of the drying program is received, after the compressor stops working, the system temperature is reduced, but at the moment, the system temperature is still at a higher temperature, and therefore after the drying program resumes operation, the fan is controlled to continuously start until the system temperature is less than or equal to the third preset temperature.
In some embodiments of the present application, based on the foregoing solution, the method further comprises:
and if a complete machine pause instruction of the clothes dryer is obtained or the opening of a door of the clothes dryer is detected, generating a pause instruction of the drying program.
It should be noted that the suspension of the drying program may be caused by a user pressing a pause key of the dryer or a door of the dryer being opened or a user operating the pause of the drying program.
In some embodiments of the present application, based on the foregoing solution, the method further comprises:
if a plurality of clothes dryers meet the drying end condition, the drying program is ended and the load of the clothes dryer is closed.
The dryer may monitor whether the environment in the heat pump system satisfies the drying condition in real time, such as detecting the humidity of the air in the heat pump system to determine whether the dryer satisfies the drying condition. After the drying process is finished, all loads (including a motor, a compressor, a fan and the like) of the washing machine are turned off.
Fig. 2 is a schematic flow chart of a sequential control logic of a clothes dryer according to an embodiment of the present disclosure. As shown in fig. 2, the logic includes at least the following steps.
Step 210: the drying process is started.
Step 220: count down T1.
After the drying program is started, the compressor starts to heat, the fan is controlled to be turned off at the moment, the temperature of the system in the heat pump system is enabled to rise rapidly, and the countdown is started, and the countdown time is assumed to be T1.
Step 230: after the countdown is finished T1, the fan is started for a time period T2.
The fan is kept off until the countdown T1 ends, step 220 is executed, and step 230 is executed after the end.
Step 240: and closing the blower T3 for a period of time, and circularly executing the step 230 and the step 240 until the drying condition is met.
