In order to solve the problems that the existing clothes drying equipment with an upper drainage system cannot discharge damp air in a cylinder due to too short opening time of a drainage pump in the drying process, and the problems of noise and too high energy consumption due to too long opening time of the drainage pump, the embodiment provides a drying control method of the clothes drying equipment with the drainage pump to solve the technical problems. The drying control method of the present embodiment is combined with the control flow chart of fig. 1, and the drying device of the present embodiment is combined with the structure diagram of the drying device of fig. 2.
After the drying device enters the drying process, damp and hot air is generated in the drying cylinder, and in order to implement condensation drying of the damp and hot air, the condensing valve 1 needs to be opened first to continuously feed cooling water to condense the damp air in the drying cylinder 8 (refer to step S1 in fig. 1). The clothes drying equipment of the embodiment is internally provided with a water collecting device, cooling water entering from a condensing valve 6 and condensed water generated by condensing damp and hot air are finally collected in a water collecting barrel, the water collecting device is connected with a water drainage pipe 10, a water drainage pump 5 is arranged in the water drainage pipe 10, and water in the water collecting device is pumped out after the water drainage pump 5 is opened. When the clothes drying equipment of the embodiment only has the clothes drying function, the water collecting device can be a water collecting box optionally, and the water collecting box can be arranged below the clothes drying cylinder optionally; when the clothes drying apparatus of the present embodiment has both the washing function and the clothes drying function, as shown in fig. 2, the water collecting device may be selected as an outer tub 9, and the clothes drying tub is disposed inside the outer tub 9.
Since the drainage efficiency of the drainage pump per unit time is much higher than the water inlet efficiency of the condensate valve and the generation efficiency of the condensed water, once the drainage pump is started, the drainage pump can quickly drain the water in the clothes drying equipment, and in order to reduce the noise problem and the energy consumption problem caused by the long-time starting of the drainage pump, the drainage pump is not directly started after the condensate valve is opened (refer to step S2 in fig. 1), but the drainage valve is opened after the condensate valve is opened for a certain time. In addition, because the damp and hot air generated in the drying process of the clothes in the drum can not be condensed in time, and larger moisture still exists in the drum, in order to simultaneously discharge the water in the drum and discharge part of the moisture which can not be condensed in the drum in time, the implementation is realized by acquiring the opening time of the condensing valve and the water level in the clothes drying equipment in a control period which is started when the condensing valve is in an opening state and the drainage pump is in a closing state; determining whether an opening condition of the drain pump in the control period is satisfied according to the opened time period of the condensing valve and the water level in the drying apparatus (refer to steps S3-S4 in fig. 1), wherein the opening condition is that the opened time period of the condensing valve and the water level in the drying apparatus satisfy a set condition; turning on the drain pump for a time period C (refer to steps S5-S6 in fig. 1) if the turn-on condition is satisfied; wherein: c is a constant greater than 0. When the drainage pump is just opened, the drainage pump quickly discharges water in the barrel, and when the water inflow of the condensation valve and the water yield of condensed water are less, the drainage pump is mainly used for discharging partial hot and humid air and convection between the air inside and outside the barrel in the opening process. And when the water inflow of the condensing valve and the generation amount of the condensed water reach a certain amount of water, the water in the clothes drying equipment is discharged by the drainage pump, and the process is circulated until the opening time C is reached.
In a specific embodiment, when either of the following conditions P1 and P2 is satisfied, the set condition is satisfied;
p1, the water level in the clothes drying equipment reaches a set water level L0;
p2, condensing valve open time t1= a + B;
wherein: a is a constant greater than 0; b is related to the load and the drying operation time, B max Is the maximum value of B; the duration t of the control period satisfies t = A + B + C, and the values of A, B and C satisfy C × L2> (A + C + B) max ) L1, preferably C L2> n (a + C + B) max ) N is more than or equal to L1 and 6 and less than or equal to 30; l1 is the water inflow of the condensation valve in unit time, L2 is the water displacement of the drainage pump in unit time, and L2>L1。
In this embodiment, when the water level reaches the drying set water level L0 or the opening time t1 of the condensation valve reaches t1= (a + B) time, the drain pump starts to be turned on. In some embodiments, the two conditions P1 and P2 can be determined simultaneously, that is, whether the water level in the clothes drying equipment reaches the set water level L0 and whether the opening time t1 of the condensation valve reaches a + B, and if one of the two conditions is true, the drainage pump is turned on. In other embodiments, two conditions P1 and P2 are sequentially determined, as shown in the control flow chart of fig. 1, that is, it is first determined whether the water level in the clothes drying apparatus reaches the set water level L0, if the set water level L0 is reached, the drain pump is started, if the set water level is not reached, it is further determined whether the opening time t1 of the condensation valve reaches a + B, if the opening time t1 of the condensation valve reaches a + B, the drain pump is started, and if the opening time t1 of the condensation valve does not reach, the water level in the clothes drying apparatus and the opening time of the condensation valve are continuously detected. Or, judge earlier whether the condensate valve open time t1 reaches A + B, if reach, open the drain pump, if reach further judge whether the water level in the drying equipment reaches set water level L0, if reach set water level L0, open the drain pump, if not reach set water level, then continue to detect condensate valve open time and drying equipment water level. The water level L0 is set to the maximum water level allowed in the drying apparatus.
The displacement L2 of drain pump unit interval is far greater than the condensate valve unit interval inflow L1 in this embodiment to the speed that the interior damp and hot air condensation of a section of thick bamboo produced the comdenstion water is also relatively slow, consequently in case the drain pump is opened, the drain pump will be fast with the water discharge in the clothing equipment that dries, when the production water yield of condensate valve inflow and comdenstion water is still less, the drain pump opens the in-process mainly used partial damp and hot air of discharge and a section of thick bamboo inside and outside air formation convection current. When the water inflow of the condensation valve and the generation amount of the condensed water reach a certain amount of water, the water in the clothes drying equipment is discharged by the drainage pump, and the process is circulated until a control period is finished. Therefore, this embodiment is through the opportunity of opening of design drain pump, makes the drain pump open the in-process and can in time discharge the water in the clothing drying equipment and can in time discharge the partly damp and hot air in the section of thick bamboo again to effectively improve the drying efficiency in stoving stage and the cooling efficiency in cooling stage, prevent that the drain pump from continuously opening the power consumption and the noise problem that bring simultaneously.
In this embodiment, the water inflow L1 of the condensate valve per unit time and the water discharge L2 of the drain pump per unit time are determined, the water discharge of the drain pump is much greater than the water inflow of the condensate valve, the time t of one control cycle is a + B + C seconds, the condensate valve is opened in the control cycle to continuously feed the condensate water a + B + C, and the maximum water inflow of the condensate water is L1 (a + B + C seconds) max + C), starting the drainage pump for C seconds to drain C X L2, wherein C X L2 is more than m (A + C + B) max )*L1,m>1, namely: the drainage quantity of the drainage pump opening time length C is far larger than the maximum water inflow of the time of a control period t when the condensation valve is opened, the drainage pump opening time length C second only needs to meet the requirement that water in the clothes drying equipment (composed of the water inflow of the condensation valve and the water quantity of the water formed by condensation of the humid air) is discharged, and meanwhile, the humid air can be timely discharged. For example, a =110 seconds, C =10 seconds, and B =0 to 20 seconds, that is, the maximum amount of condensed water (a + C + B) that enters max ) L1 is 140L 1, and the drain pump can discharge the water in the barrel and discharge the humid air for a long time within 10 seconds, or a =55 seconds, C =5 seconds, and B = 0-10 seconds. The method is characterized in that the method only needs to meet the requirements that water in the clothes drying equipment is drained within the set ranges of A, B and C, the water in the clothes drying equipment does not reach the drying set water level L0 within the control period t, a long period of time is reserved for draining humid air, and meanwhile, the starting time of the drainage pump is not suitable to be too long.
In one embodiment, the size of the parameter B is determined according to a parameter B-load amount-drying operation time comparison table shown in table one, and in the comparison table, the parameter B is in positive correlation with the load amount and the drying operation time respectively, that is, when the load is larger and the drying operation time is larger, the value of the parameter B is larger. The value range of B is more than 0 and less than or equal to 20s.
Table one: parameter B-load-drying operation time comparison table
Since the drying operation time is longer and the parameter B is larger under the condition of a certain load, in the period (a + B + C), the larger B is, the smaller the humidity in the cylinder is reduced, so that the occupation ratio of the drainage pump opening time C in the whole control period t is shorter, namely the drainage pump opening proportion time in the period is smaller. When the humidity of air in the drum is high in the initial drying stage, the amount of water condensed into water by humid air in the drum is high, the water drainage pump accounts for a period longer than the starting time in a control period (A + B + C), and the time of air convection formed inside and outside the drum is long; with the drying, the length of the drying time is long, the parameter B is reduced, the humidity of the air in the barrel is low, the water quantity of the moisture air condensed into water in the barrel is low, the ratio of the opening time of the drainage pump in unit time (A + B + C) is short, and the time for forming air convection is short. This embodiment can effectively improve drying efficiency through the machine time of opening of so control drain pump, guarantees both to discharge the comdenstion water completely in a control cycle, can also discharge partial damp and hot air simultaneously, can also prevent that the drain pump from opening the time overlength, brings noise and energy consumption.
The drying process in this embodiment is a process of drying the clothes by the clothes dryer, and is not limited to the drying stage of raising the temperature in the drum.
Further optionally, the parameter a is related to a parameter C, a = k × C, k > 0. Optionally, the value range of the parameter C is 0 < B ≦ 20s, a = 5-20C, or a = 8-13C, or a = 11-15C.
Further optionally, after the draining pump is turned on and maintained for the time period C, the drying control method further includes:
judging whether the drying end condition is met, and if the drying end condition is met, controlling a condensation valve and a drainage pump to be closed; if the drying end condition is not satisfied, the drainage pump is controlled to be closed, the opening state of the condensation valve is maintained, and the control process of a new control cycle is entered again (refer to steps S8-S9 in fig. 1). After the draining pump is started for a time length C, judging whether the drying stage is finished or not, if the drying stage is finished, closing the condensing valve and closing the draining valve, and if the drying stage is not finished, continuously starting the condensing valve, closing the draining pump, and acquiring the started time length of the condensing valve and the water level in the clothes drying equipment again; and determining whether the starting condition of the drainage pump in the control period is met or not according to the opened time length of the condensation valve and the water level in the clothes drying equipment, and starting the drainage pump and maintaining the time length C under the condition that the starting condition is met, so as to continuously iterate the control logic in the figure 1 until the drying is finished.
