Technical Field

The present invention relates to a laundry treating apparatus and a control method thereof.

Background

An existing independent condensing drum dryer includes a heat pump system, a condensate tank for containing water condensed during a laundry drying process, and a water pump for pumping the water in the condensate tank to an outside of the dryer or a water storage box of the dryer.

In the prior art, because the clothes dryer can continuously produce condensed water in the operation process, when the water level in the condensed water tank reaches a preset value or the clothes dryer operates to a rated time, the water pump is started to continuously pump water for a long time. In the process, the water pump is in a continuous operation state, continuous negative pressure generated by continuous water pumping for a long time easily sucks air to cause water and vapor mixing, so that high noise is generated, and the user experience is poor.

Disclosure of Invention

In view of the above, the present invention is directed to a clothes treating apparatus and a control method thereof, so as to solve the problem that a water pump of a clothes dryer in the prior art is likely to cause water-vapor mixing and generate noise during water pumping.

In order to achieve the purpose, the technical scheme of the invention is realized as follows:

a control method of a laundry treating apparatus, comprising: s1, starting a clothes drying process; s2, the central processing unit acquires the water level value A in the condensate water tank in real time; s3, the central processing unit judges whether A is smaller than a preset water level A0, if yes, the step S4 is carried out, and if not, the step S5 is carried out; s4, the central processing unit controls the water pump to intermittently pump water; and S5, sending prompt information to the user. Thereby through control water pump intermittent type formula operation, can reduce the time of suction air and the air quantity of suction simultaneously, can reduce the emergence of steam mixing phenomenon effectively for in the water pump process of drawing water, because of the produced noise of steam mixing phenomenon can be controlled effectively, and can in time remind when the water level is unusual

Further, step S4 includes: s41, the central processing unit judges whether the timing duration is greater than the preset duration, if yes, the step S42 is carried out, and if not, the step S41 is returned; s42, the central processing unit controls the water pump to start; s43, the central processing unit judges whether the starting time t of the water pump is greater than a first rated time t 1; if yes, go to step S44; otherwise, returning to step S43; s44, the CPU controls the water pump to stop; s45, the central processing unit judges whether the shutdown time T of the water pump is greater than a second rated time T2; if yes, step S46 is performed by adding 1 to the first count value; otherwise, returning to step S45; s46, the CPU determines whether the first count value is greater than the first preset value M, if yes, the process returns to step S2, and if not, the process returns to step S42. Wherein t1 is 10-20s, t2 is 5-15s, and M is 2-5. Thereby when the water level is normal, open or close through the reasonable control water pump at the in-process of drawing water, make the water pump intermittent type formula operation, can reduce the time of suction air when drawing water, simultaneously after drawing water and stopping, the condensate tank can be refluxed to the water that is not drawn away in the drinking-water pipe, when drawing water next time, this part of water can directly be inhaled to the water pump, reduce the space of suction air, can reduce the volume of suction air promptly, thereby can reduce the time of suction air and the air quantity of suction simultaneously, can reduce the emergence of steam mixing phenomenon effectively, make in the water pump process of drawing water, the noise that produces because of steam mixing phenomenon can be controlled effectively.

Further, step S5 includes: s51, the central processing unit controls the water pump to start; s52, the central processing unit judges whether the starting time t of the water pump is greater than a third rated time t 3; if yes, go to step S53; otherwise, returning to step S52; s53, the CPU controls the water pump to stop; s54, the central processing unit judges whether the shutdown time T of the water pump is greater than a fourth rated time T4; if yes, step S55 is performed by adding 1 to the second count value; otherwise, returning to step S54; s55, the central processing unit judges whether the second count value is larger than a second preset value N, if yes, the step S56 is carried out, and if not, the step S3 is returned; and S56, stopping the clothes treatment device and reminding a user to clean the water box. Wherein t3 is 10-20s, t4 is 5-15s, and N is 2-5. Therefore, after the water level value A in the condensed water tank exceeds the preset water level A0, intermittent water pumping of the water pump is continued, on one hand, the situation that the water level sensor is mistakenly touched to cause signal errors is prevented, on the other hand, after water pumping, if the A still exceeds the preset water level A0, the water box is possibly filled, the clothes treatment device is stopped in time, the phenomenon that the condensed water overflows the condensed water tank due to too much condensed water is avoided, and meanwhile, a user is reminded to clear the water box.

Further, after the step S56, the step S5 includes: s57, the CPU judges whether the user restarts the clothes processing device, if yes, the third counting value is added with 1, step S58 is carried out, if no, the step S57 is returned; s58, the CPU judges whether the third counting value is larger than the third preset value K, if yes, the clothes processing device stops, and sends out a water full alarm to the user, if not, the step returns to the step S51. Wherein K is 1-3. Therefore, by judging the restarting times of the clothes treatment device, the safety protection can be effectively carried out on the restarting condition of the clothes treatment device which is stopped in the step S56 directly aiming at the condition that a user does not pay attention to the water quantity of the water box because of carelessness, and the overflow of condensed water is avoided; in addition, if the user cleans the water box, and if a water full alarm exists, the fault of the water level sensor or other parts in the clothes treatment device can be indicated, so that the user can conveniently check the fault.
