Description

Drying method and device

Technical Field

The invention relates to the field of household appliance design, in particular to a drying method and a drying device.

Background

Along with the improvement of life quality and serious outdoor environment pollution, outdoor space is limited, and the clothes dryer or the washing and drying integrated machine is not suitable for airing more and more, and more people can also choose to buy the clothes dryer or the washing and drying integrated machine while choosing the washing machine. Especially, the southern area is wet, the clothes are not washed and dried in time, the clothes are easy to mildew, and the use frequency is high. The clothes dryer can quickly evaporate and dry moisture in the wet clothes. The dryer type that can see on the market has direct vent dryer, heat pipe water condensing dryer, heat pipe air condensing dryer and heat pump air condensing dryer, wherein:

the working principle of the direct-exhausting clothes dryer is that hot air is directly exhausted out of the machine through a drain pipe after moisture is taken away. The clothes dryer has relatively simple structure and low cost, and is a drum-type clothes dryer with relatively low price on the market.

Compared with a direct-exhaust type clothes dryer, the clothes dryer has the advantages that a condensation process is added, namely, water vapor blown out in the drying process is discharged in a cold water cooling mode through a condenser, and compared with the direct-exhaust type clothes dryer, the space is not affected by the fact that air with the water vapor is directly discharged, but hot air is discharged from the clothes dryer body, and the indoor temperature is affected to a certain extent.

The principle of the heat pipe air condensation type clothes dryer is the same as that of the heat pipe water cooling type clothes dryer, and only compared with the former condensation mode, the heat pipe air condensation type clothes dryer has the advantages that cold water is changed into cold air, so that the heat pipe air condensation type clothes dryer is relatively more environment-friendly and saves water.

Compared with a heat pipe type dryer, the heat pump air condensation type dryer has the advantages that the temperature of hot air blown out of the heat pump dryer is more uniform, the same quantity of clothes are dried, the power consumption is lower, meanwhile, heat only circulates in the machine, the temperature of air discharged out of the machine is equivalent to the room temperature, and no influence is caused on the surrounding environment.

The inventor of the present application finds that the above-mentioned solution of the prior art has drawbacks in implementing the present invention. The clothes are abraded greatly in the drying process of the clothes dryer on the current market. And with the increasing popularization of multifunctional clothes in the market, such as sweat absorption, antibiosis and the like, the clothes can lose the original functionality in a short time by adopting the current drying procedure.

In view of the above technical problems, no good solution is available in the prior art.

Fig. 1 is a flowchart of a drying method according to an embodiment of the present invention. As shown in fig. 1, a drying method provided by an embodiment of the present invention may be performed by a dryer, and the method may include:

s101, a swinging step of making a roller of the clothes dryer execute swinging action;

s102, a shaking and scattering step of making the drum of the clothes dryer execute shaking and scattering actions; and

s103, obtaining the judging step of the judging result.

In an embodiment, the swinging motion may include that the drum rotates to make the laundry in the drum rotate along a first rotation direction from the lowest point of the drum to a first swinging point, then return along a second rotation direction, rotate along the lowest point of the drum to a second swinging point, and then return along the first rotation direction to the lowest point of the drum, wherein the swinging point is the highest point reached by the laundry rotating along the drum, or rotate along the drum to a point with zero speed (i.e. will start to rotate along the other direction). The first and second swing points may be the same height and both lower than the highest point of the drum. In an embodiment, the swinging step may be repeatedly performing the swinging action.

In an embodiment, the shaking-out action may include the drum rotating or swinging such that the laundry to be dried in the drum falls as the drum rotates from said lowest point of the drum to the highest point of the drum. The laundry may be thrown away when it falls from the highest point of the drum. In an embodiment, the dithering step may be repeatedly performing the dithering action.

In an embodiment, the trunk determination may be performed by a time trunk determination method or a temperature and humidity trunk determination method. The time dry judgment can judge that the drying is finished when the drying process reaches the drying time according to the drying time (namely dry judgment condition) corresponding to the weighing value of the clothes to be dried. The temperature and humidity judging method can judge the drying progress according to the temperature and humidity value acquired from at least one position in the roller or at least one position of an air outlet of an air duct of a dryer or an air outlet of a condenser, and when the acquired temperature and humidity reach a preset condition (namely a drying judging condition), for example, when the acquired temperature and humidity are smaller than or equal to a preset threshold value, the drying is judged to be finished. In an embodiment, the step of judging whether the trunk condition is satisfied may be a step of judging whether the trunk condition is satisfied.

Fig. 2 is a flowchart of a drying method according to another embodiment of the present invention.

As shown in fig. 2, the method may include:

s201, acquiring a weighing value of the clothes to be dried;

in an embodiment, the laundry to be dried may be weighed by a sensor such as a pressure sensor or by an inertia calculation method. In the embodiment of sensor weighing, the empty weight of the drum of the clothes dryer and the weight of the drum after the clothes to be dried are added can be determined by a pressure sensor arranged at a weighing position such as a rotating shaft of the drum, and the weight value of the clothes to be dried is obtained by subtracting the empty weight of the drum of the clothes dryer and the weight of the drum after the clothes to be dried are added. The inertia calculation method can calculate the variation of the rotational inertia of the drum before and after the clothes to be dried are put in the drum, and then obtain the weighing value of the clothes to be dried by utilizing the relationship between the variation and the mass.

S202, judging whether the weighing value is smaller than a preset weight value or not; when the weight value is smaller than the preset weight value, only the swing step S101 and the dry judgment step S103 may be performed.

The drum will move the laundry during the drying process, and the same motion pattern may cause different degrees of wear for different weights of laundry. Therefore, it may be considered to adopt a corresponding drying strategy for the weight of the laundry to reduce the wear of the laundry. In an embodiment, the laundry weight range may be divided by setting a weight preset value, and then the drying strategy may be performed for different weight ranges. An exemplary weight preset value may be any of 1/3 to 1/4 of the rated capacity of the dryer.

In an embodiment, when the weighing value is less than the weight preset value, it may be considered that the laundry in the drum is less and thus the shaking may be optional, in which case only the swing step S101 and the dry judging step S103 may be performed.

In an embodiment, the drum may be oscillated reciprocally about the shaft by controlling the drum to oscillate reciprocally, for example, at a speed of 100 and 200rmp, in the range of-60 ° to 60 ° (assuming 0 ° at the lowest point of the drum). An exemplary swing motion process may be as shown in fig. 5, wherein a swing motion may include that the drum rotates to return the laundry to be dried in the drum along a first rotation direction (for example, a direction indicated by an upper arrow in fig. 5) along with the drum from a drum lowest point C to a first swing point a and then along a second rotation direction (for example, a direction indicated by a lower arrow in fig. 5), rotates to a second swing point B after passing through the drum lowest point C, and then returns to the drum lowest point C along the first rotation direction, wherein the heights of the first swing point a and the second swing point B may be the same and are lower than a highest point D of the drum. For example, the roller is made to do reciprocating swing motion at the rotating speed of 100-200rmp of the speed v1, wherein the included angles theta between the swing points A and B of the swing motion and the connecting lines OA and OB of the roller center O and the connecting line OC of the lowest point C of the roller and the roller center O are less than or equal to 60 degrees.

Fig. 3 is a flowchart of a drying method according to still another embodiment of the present invention. As shown in fig. 3, when it is determined at S202 that the weighing value is greater than or equal to the preset weight value (e.g., 1/3 of the rated capacity of the dryer), the swinging step, the shaking step, and the judging step may be cyclically performed until the judging result satisfies the judging condition (e.g., time judging or temperature and humidity judging). In an embodiment, a stationary step may also be included between the swinging step and the shaking step. Accordingly, embodiments provide a method further comprising determining a rest time for the resting step according to the weighing value of the laundry to be dried. Wherein the laundry to be dried is made to stand at the bottom of the drum of the dryer in the standing step.

In an embodiment, as shown in fig. 3, in the swing step S301, the drum of the dryer may be made to perform a first preset number of times n1 swing motions; in the stationary step S302, the drum may be stationary for a preset time; in the shaking step S303, the drum may be caused to perform a second preset number of shaking actions n2 times; wherein n1 > n 2. In the step S304, a decision may be performed to obtain the decision result.

In an embodiment, the drum may perform the swing motion at a v1 speed in the swing step S301; the drum may perform the shaking motion at a v2 speed in the shaking step S303; wherein v1 < v 2.

In an embodiment, step S301 may perform the same actions as step S101, for example, as shown in fig. 5 and described above in conjunction with fig. 5, the swinging is achieved by controlling the drum to oscillate back and forth relative to the shaft. In an embodiment, the number of swing may be the same or different according to the weight of the laundry to be dried. For example, a greater number of swings than S101 may be employed in S301. In alternative embodiments, the number of yaw employed in S301 may be the same as in S101.

In an embodiment, the preset time for which the drum is stationary in S302 may be associated with a weighing value of the laundry to be dried. In a preferred embodiment, the preset time is a maximum value when the weighing value is the rated capacity 1/3 of the dryer. According to the actual measurement, the relationship between the preset time and the weighing value of the clothes to be dried can be as shown in fig. 6, the ordinate is the time abscissa is the ratio of the mass of the clothes to be dried to the rated capacity of the clothes dryer, wherein M0 is the rated capacity of the clothes dryer, and T0 is the maximum rest time. As shown in FIG. 6, when the amount of the laundry is too small or too large, the drying time is not too long. When the laundry is too small, the laundry is easily damaged by an excessively long resting time. When too much clothes are left, the clothes are accumulated due to static state, the heat dissipation effect is poor, and the performance of the clothes is also affected. As can be seen from fig. 6, when the laundry mass ratio is 1/3, the stationary time is longest and the drying effect is also the best (i.e., the wear is the lowest and the drying effect is also better). In an embodiment, T0 may be set to not more than 60s, and preferably T0 may be 30 s.

In the embodiment, the same action as step S102 may be performed in step S303, for example, one shaking action may include drum rotation or swinging to make the laundry in the drum fall off as the drum rotates from the lowest point of the drum to the highest point of the drum. The laundry may be thrown away when it falls from the highest point of the drum. In an embodiment, the shaking step S303 may be repeatedly performing the shaking motion n2 times. When the drum rotates or swings, the clothes fall off along with the drum when passing through the highest point of the drum, and the clothes are scattered, so that the position of the clothes is greatly changed. To achieve the dithering, the rotational speed v2 of the drum may be set at 500-. The drum may be continuously or reciprocally rotated at a set rotation speed.

In an embodiment, the stem judgment methods employed in S304 and S103 may be the same.

In an embodiment, the method may further comprise: and changing the ratio of the first preset number n1 to the second preset number n2 according to the judgment result. The laundry drying reduces the weight so that the wear of the laundry by the shaking motion will be gradually reduced, and therefore, the ratio between the first preset number n1 and the second preset number n2 may be changed as the laundry is gradually dried, so that the ratio of the second preset number n2 in a drying process including, for example, a swinging step, a resting step, a shaking step, and a drying judging step is increased with respect to the first preset number n 1.

In an embodiment, when the drying time is up to the preset time or the humidity is reduced to the preset humidity, n2 and/or n1 may be adjusted such that the adjusted n 1: the value of n2 decreases. As the laundry is gradually dried, in one embodiment, the value of n1 may be maintained, increasing the value of n 2. In another embodiment, the value of n1 may be decreased while the value of n2 is increased. In an embodiment, the pre-adjustment n 1: n2 ═ 5: 1, adjusted n 1: n2 ═ 3: 1. more specifically, 1 dithering action can be executed after 5 dithering actions are executed before adjustment; after adjustment, the shaking motion can be executed for 1 time after 3 times of swinging motion is executed. In a preferred embodiment, the value of n1 may be reduced, leaving the value of n2 unchanged. Along with the clothing is dry gradually, need tremble more frequently and make the clothing scatter, make damp and hot gas give off the discharge, improve the frequency of trembling with this mode and can dry the degree that the process can adapt to current clothing more, improve the efficiency of drying. In a different embodiment, instead of varying the ratio of n1 to n2 as the laundry dries, the time of the stationary process may be adjusted simultaneously, for example, according to the curve shown in fig. 6.

Fig. 4 is a flowchart of a drying method according to still another embodiment of the present invention. As shown in fig. 4, when it is judged at S202 that the weighing value is greater than or equal to the preset weight value (e.g., 1/3 of the rated capacity of the dryer), the swinging step, the shaking step, and the judging step may be cyclically performed until the judging result satisfies the judging condition (e.g., time judging or temperature and humidity judging). In an embodiment, a stationary step may also be included between the swinging step and the shaking step. Accordingly, embodiments provide a method further comprising determining a rest time for the resting step according to the weighing value of the laundry to be dried. Wherein the laundry to be dried is made to stand at the bottom of the drum of the dryer in the standing step.

In an embodiment, as shown in fig. 4, in the swing step S401, the drum of the dryer may be swung for a first preset time m 1; in the stationary step S402, the drum may be stationary for a preset time; in the shaking step S403, the drum may be caused to perform a shaking motion for a second preset time m 2; wherein m1 is more than m 2. In the step S404, a decision making may be performed to obtain the decision making result.

In an embodiment, the drum may perform the swing motion at a v1 speed in the swing step S401; the drum may perform the shaking motion at a v2 speed in a shaking step S403; wherein v1 < v 2.

In an embodiment, step S401 may perform the same actions as step S101, for example, as shown in fig. 5 and described above in connection with fig. 5, the swinging is achieved by controlling the drum to oscillate back and forth with respect to the shaft. In an embodiment, the time of the swing may be the same or different according to the weight of the laundry to be dried. For example, more slew time than S101 time may be employed in S401. In alternative embodiments, the slew time employed in S401 may be the same as in S101.

In an embodiment, the preset time for which the drum is stationary in S402 may be associated with a weighing value of the laundry to be dried. In a preferred embodiment, the preset time is a maximum value when the weighing value is the rated capacity 1/3 of the dryer. According to the actual measurement, the relationship between the preset time and the weighing value of the laundry to be dried can be as shown in fig. 6. When the clothes mass ratio is 1/3, the standing time is longest, and the drying effect is also the best (namely, the abrasion is the lowest, and the drying effect is also better). In an embodiment, T0 may be set to not more than 60s, and preferably T0 may be 30 s.

In the embodiment, the same action as step S102 may be performed in step S403, for example, one shaking action may include that the drum rotates or swings to make the laundry in the drum fall down as the drum rotates from the lowest point of the drum to the highest point of the drum. The laundry may be thrown away when it falls from the highest point of the drum. In an embodiment, the shaking step S403 may be repeatedly performing the shaking motion n2 times. When the drum drives the clothes to rotate or swing, the clothes fall off along with the drum when passing through the highest point of the drum due to the rotation or the swing, and the clothes are scattered, so that the position of the clothes is greatly changed. To achieve the dithering, the rotational speed v2 of the drum may be set at 500-. The drum may be continuously or reciprocally rotated at a set rotation speed.

In an embodiment, the stem judgment methods used in S404 and S103 may be the same.

In an embodiment, similar to the above embodiment, the method may further comprise: the ratio of the first preset time m1 to the second preset time m2 is changed according to the outcome of the arbitration. When the drying time is up to the preset time or the humidity is reduced to the preset humidity, adjusting m2 and/or m1 to enable m 1: the value of m2 decreases.
