The drying system (the compressor is operated) can be started before the first stage, namely the steam spraying stage, the air channel is preheated, the condition that condensate water is generated in the air channel with lower temperature after steam is generated can be reduced, and the steam utilization efficiency is improved.
Specifically, as shown in fig. 4 and 5, after the steam deodorization procedure is selected, the liquid level probe 17 in the steam heating device 4 starts to detect whether the liquid level in the steam heating device satisfies the condition of turning on the steam electric heating 16, and if the condition is satisfied, that is, the low liquid level probe is turned on, the steam electric heating 16 is turned on. After the steam electric heater 16 is started, the circulating fan and the drainage pump are started, and the compressor starts to operate at low frequency. The steam temperature sensing bulb 15 detects the steam temperature in real time, when the temperature feedback value is 99 +/-1 ℃, the mainboard starts to record the steam generation time point, and simultaneously starts to record the probe on-time point until the steam generation time S2 set by the program is reached, or the probe detects the off-time S3. If the disconnection of the liquid level probe is not detected within the set steam generation time S2, namely S2 is more than or equal to S3, the first stage is ended, the steam electric heating is disconnected, and the second stage is started. If the liquid level probe is detected to be disconnected in the steam generation process, it is determined whether the performed steam generation time (i.e., the liquid level probe on-time) S3 is less than the minimum steam generation time (8min), and if the minimum heating time is not met, the steam inlet valve 13 is fed with water and reheated to generate steam until the condition of entering the second stage is reached. In this stage, along with steam gets into in the bucket, the temperature rose in the bucket, and the bucket internal pressure also increases thereupon, and the air in the bucket diffuses to the air outside the washing machine this moment, and after the bucket internal pressure reduces gradually, the new trend outside the section of thick bamboo is sucked into in the bucket again gradually, reaches the purpose of changing new trend, and partial peculiar smell accessible drain pump is discharged outside the section of thick bamboo.
As shown in fig. 3, after the steam electric heating 16 is turned off, the second stage, i.e. the drying stage, is started, in the process, the compressor runs at high frequency, and meanwhile, the drying spray valve 12 is intermittently opened for S5 time within the preset time, and experiments prove that the water valve can achieve a better odor removing effect after the intermittent opening time of about 5-15 min. After the drying spray valve 12 is closed, the compressor is closed after continuously running for 5 to 10 min. At this stage, the purpose of dissolving the peculiar smell gas in the barrel is achieved by spraying water in the air duct, and the water in the air duct is discharged out of the barrel through the drainage pump, so that the purpose of removing the peculiar smell is achieved. In fig. 4, 14 is a steam outlet, in the present application, the time S1 may be 5S, S2 may be 10min, S4 may be 10min, S5 may be 5S, S6 may be 5min, and S4 is the measured value.
