Preferably, the clothes care device further comprises a rear drum condensation air duct 5, a second air outlet 51 is arranged in the top area of the vertical wall of the rear drum 1, the second air outlet 51 is communicated with the rear drum condensation air duct 5, and the second air outlet 51 can partially guide the hot air flow sent out by the drying air duct 72 to the inner surface position of the vertical wall of the rear drum 1, so that heat exchange is more thorough, and drying efficiency is further improved. The air outlets of the rear condensation duct 2 and the rear condensation duct 5 are summarized at the inlet position of the drying duct 72, where the corresponding return air humidity sensor 61 is disposed, and here, a fan 73 is generally disposed to drive the airflows in the two ducts simultaneously.

According to an embodiment of the present invention, there is also provided a laundry care device including the above-described laundry care device, for example, a washing and drying integrated machine, a clothes dryer, or the like.
According to an embodiment of the present invention, there is also provided a laundry care device control method for controlling an operation of the laundry care device, including the steps of:
an acquisition step of acquiring real-time condensation comprehensive efficiency DeltaSs when the clothes care device runs in a drying mode;
and judging and executing the step, wherein the opening and closing time of the control valve 4 is controlled and regulated according to the magnitude relation between the real-time condensation comprehensive efficiency DeltaSs and the preset condensation comprehensive efficiency DeltaSy (in a specific embodiment, deltaSy is more than or equal to 3% and less than or equal to 5%, which is positively related to the drying time and can be increased or decreased according to the program setting time).
Specifically, the judging and executing step includes:
when Δss < Δsy, controlling to increase the opening duration of the control valve 4 and decrease the closing duration of the control valve 4; and when DeltaSs is not less than DeltaSy, the control valve 4 can be controlled to keep the current opening and closing time.
According to the technical scheme, the opening and closing time of the control valve 4 can be controlled and adjusted according to the relation between the condensation comprehensive efficiency DeltaSs of the clothes care device and the corresponding preset value, namely when the condensation comprehensive efficiency is lower than the preset condensation comprehensive efficiency, the opening time of the control valve 4 is controlled to be increased, the closing time of the control valve 4 is controlled to be reduced, when the condensation comprehensive efficiency is not lower than the preset condensation comprehensive efficiency, the current opening time and closing time of the control valve 4 are controlled to be kept, so that the total consumption of condensed water is reduced while the higher drying efficiency is kept in a drying mode of the drying integrated machine, and the energy efficiency of the clothes care device is beneficial to reaching standards.
The condensation comprehensive efficiency Δss can be obtained by the difference between the in-cylinder real-time humidity Φk obtained by the in-cylinder humidity sensor 62 and the return air real-time humidity Φz obtained by the return air humidity sensor 61, where Δss= ΔΦs = Φk- Φz. It is needless to say that the temperature may be obtained by a degree of decrease in temperature, and the humidity sensor may be replaced with a temperature sensor provided at a corresponding position, and the present invention is not intended to limit the manner of obtaining the condensation integrated efficiency Δss as is well known in the art.
Preferably, when Δss is not less than Δsy, it is determined whether the number Ns of times for continuously satisfying Δss is not less than Δsy exceeds a preset number Ny, and when Ns is not less than Ny, the control valve 4 is controlled to maintain the current opening and closing time, so that the instantaneous occurrence of Δss not less than Δsy due to other accidental factors can be prevented, and the reliability of the control strategy is ensured. The opening and closing time length of the control valve 4 is a fixed value, for example, the fixed value is 60 s-120 s, the integral multiple of 10 is used, that is, the opening and closing time length is the fixed time length, the time length of the increase of the opening time length is equal to the time length of the closing time length, so that the total time length of the opening time length and the closing time length are constant, that is, the increase value (integral divisor, for example, 5s and 10 s) or the decrease value of the opening time length of the control valve 4 is adjusted each time, and the simple control of the control valve 4 can be facilitated. As mentioned above, the flow rate of the main condensation water valve is a fixed value, which is beneficial to controlling the flow rate of the condensed water.
Before the real-time condensation comprehensive efficiency DeltaSs is obtained, the method further comprises the steps of obtaining the real-time drying temperature Ts in the rear cylinder 1, controlling the condensation main water valve and the control valve 4 to be opened when the Ts is more than or equal to Ty, and controlling the condensation main water valve and the control valve 4 to be closed when the Ts is less than Ty, wherein Ty is a preset drying target temperature, ty can be set to be any value of 80-90 ℃ according to a program, namely, when the drying temperature is stabilized above the preset drying target temperature, introducing corresponding condensate water to perform condensation dehumidification, which is beneficial to quickly heating the temperature in the cylinder and improving the drying efficiency.
The following describes the technical scheme of the present invention in detail with respect to a preferred embodiment of the present invention.
After the clothes start to run the drying program, the hot and humid air in the drum is condensed and dehumidified through the bottom wall surface of the rear drum (namely the inner surface of the vertical wall of the rear drum, the same applies below) and the condenser (namely the rear air duct condensation structure 21, the same applies below), and then the hot and humid air is heated by the heating pipe (namely the drying air duct 72) and then changed into dry air, and the dry air enters the drum through the air inlet to dry the clothes. In the initial drying stage, the fan 73 and the heater are operated to quickly heat up the inside of the cylinder, and when the temperature T of the temperature sensing bag 74 is greater than the critical temperature T0, the pre-drying stage is finished and the final drying stage is finished. After entering the main water valve, the condensed water is respectively conveyed to the inner wall surface of the rear cylinder and the inside of the condenser through two branches (namely the first condensed water inlet pipe 111 and the second condensed water inlet pipe 211), hot humid air dried by clothes is firstly subjected to condensation dehumidification on the bottom wall surface of the rear cylinder, then subjected to secondary dehumidification through the condenser, the total water flow Q is unchanged, the solenoid valve (namely the control valve 4 and the same below) starts to run periodically after stable water supply, the ty0 time is closed after tx0 time is opened, the water flow Qi of the rear cylinder is equal to the water flow Qj of the condenser during the opening period, and the water flow Qi=0 and Qj=Q during the closing period. The difference delta phi between the humidity phi k of the in-cylinder humidity sensor 62 and the humidity phi z of the return air humidity sensor 61 represents the condensation comprehensive efficiency, the starting and stopping time of the electromagnetic valve is adaptively adjusted according to the condensation comprehensive efficiency, when delta phi reaches a preset value delta phi 0, the period of txn and tyn is kept unchanged until the drying is completed, and the main water valve of the condensed water is closed.
The specific program control and embodiments are as follows:
after the drying program is started, in the pre-drying stage, the whole temperature in the cylinder rises, the main condensation water valve is closed to avoid affecting the temperature rising rate, the temperature T of the air inlet channel is used for comparing the preset temperature T0, if T is more than or equal to T0, the pre-drying stage is finished, and the main condensation water valve enters the formal drying stage.
The main condensation water valve and the electromagnetic valve are opened, the total water flow Q is unchanged, the back-drum condensation water flow Qi=Qj, the electromagnetic valve starts to be periodically started and stopped after stable water supply, the period duration T0 is unchanged, delta phi=phi k-phi z is calculated, if the period opening duration tx0 of the electromagnetic valve is smaller than a preset value delta phi 0, delta T is increased, the period closing duration ty0 is correspondingly reduced by delta T, delta phi is calculated for each interval delta T, the operation is repeated, namely, the nth time (n is more than or equal to 5) is used for adjusting the electromagnetic valve to be opened for txn=tx0+ndelta T, the closing time is tyn=ty 0-ndelta T, until delta phi is more than or equal to delta phi 0, and the electromagnetic valve keeps the starting and stopping duration after the last adjustment unchanged until the drying is finished. After the drying is finished, the main condensation water valve is closed, and the machine stops running.
It will be readily appreciated by those skilled in the art that the above advantageous ways can be freely combined and superimposed without conflict.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention. The foregoing is merely a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that modifications and variations can be made without departing from the technical principles of the present invention, and these modifications and variations should also be regarded as the scope of the invention.
