Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Fig. 1 is a flowchart illustrating a method of determining a drying load according to an exemplary embodiment, as shown in fig. 1, the method of determining a drying load includes the following steps S11-S12:

in step S11, it judges whether the drying load in the laundry treating tub is overloaded or not by at least two parameters among the eccentricity value, the weighing value and the power;

in step S12, the drying load is considered to be a multi-load only when at least two parameters among the eccentricity value, the weighing value, and the power all reach preset values.

In one embodiment, the washer-dryer has become increasingly popular, but the user is still confused as to the selection of the drying mode. Because of the difference in the water absorption, etc. of various kinds of laundry, it is difficult for a user to easily determine a drying mode according to the volume of the laundry or the mass of the laundry. This will cause the authentication and selection to be annoying to most users, and if the selection is wrong, the laundry may not be dried or the laundry may be excessively heated to cause deformation. According to the technical scheme, a user does not need to manually operate, the washing and drying all-in-one machine can conveniently determine the drying type of the drying load according to the load parameters of the drying load (clothes to be dried) before the drying mode starts, and then automatically select the drying mode matched with the drying load.

The drying load may be classified into two types, one being a multi-load type and the other being a load type, according to a load parameter of the drying load. For example, the preferred range of multi-load is 70% -99% of the maximum load, and the preferred range is 80%. The multi-load type washing and drying integrated machine uses a drying mode of an enhanced plate, and parameters such as drying temperature, drying time, rotation-stop ratio in a drying stage and the like need to be adjusted. Other load types can properly finish the drying of the clothes only by using a normal drying mode.

According to the technical scheme in the embodiment, a user does not need to manually set the drying mode, the load type of the drying load can be automatically analyzed by obtaining any one or more of the eccentricity value, the weighing value and the power of the drying load, and therefore the corresponding drying mode is worked out.

In one embodiment, as shown in FIG. 2, step S11 includes the following steps S21-S23:

in step S21, acquiring an eccentricity value of the drying load;

in step S22, a weighing value of the drying load is acquired;

in step S22, the power is acquired at a preset first rotational speed.

In one embodiment, the washer-dryer is accelerated from zero, typically during the phase when the speed reaches 35-50 rpm (the number of revolutions in a minute), during the swing phase. The stage when the rotating speed reaches 90rpm-95rpm is the better stage for obtaining the eccentricity value of the drying load. The stage of the rotation speed reaching 120rpm-150rpm is the preferable stage of obtaining the weighing value of the drying load. That is, generally, the weighing value is generally acquired after the eccentricity value is acquired. And the power is determined according to the preset first rotating speed, and the power is measured when the washing and drying integrated machine reaches the preset first rotating speed. The power and the drying load are in direct proportion, and the preferred first rotation speed is 50rpm and 93 rpm. The rotation speed range in the whole process of acquiring the eccentricity value, the weighing value and the power of the drying load is 30rpm-180 rpm.

In one embodiment, as shown in FIG. 3, step S23 includes the following step S31:

in step S31, the power is acquired when the preset first rotation speed is maintained for a preset time period.

In one embodiment, when the preset first rotational speed is maintained for a preset period of time,because no acceleration is involved, the power is in a steady state, at which point the power draw more accurately reflects the drying load. For example, the rotating speed of the drum of the washing and drying integrated machine reaches N₁Then, after holding for x seconds, the power W is removed. Wherein, the selection range of x seconds is 3 seconds to 30 seconds, and the preferred selection is 10 seconds.

In one embodiment, as shown in FIG. 4, step S23 further includes the following step S41:

in step S41, the power is obtained during the process of increasing from the preset second rotation speed to the preset third rotation speed.

In one embodiment, when the rotation speed of the drum of the washing and drying machine is increased, the rotation speed of the laundry (i.e. the drying load) in the drum is also synchronously increased, and the power required to be provided by the washing and drying machine is in direct proportion to the mass of the laundry in the drum, so that the power obtained at this time can well reflect the mass of the drying load. For example, the drum of the washing and drying machine is increased to a preset third rotating speed N at a preset second rotating speed N2₃At this stage, the power at this time is acquired.

In one embodiment, as shown in FIG. 5, step S12 includes the following steps S51-54:

in step S51, performing an eccentricity value determination that determines whether the eccentricity value of the drying load is greater than a preset multi-load eccentricity threshold value;

in step S52, performing a weighing value determination, where the weighing value determination is to determine whether the weighing value of the drying load is greater than a preset multi-load weighing threshold;

in step S53, performing power determination, where the power determination is to determine whether the weighing value of the drying load is greater than a preset multi-load weighing threshold;

in step S54, a multi-load determination is made as to whether any two of the eccentricity value determination, the weight value determination, and the power determination are true.

In one embodiment, in the case where there are three factors for the judgment of the drying load, the type of the drying mode may be identified as long as two of the factors are satisfied. The factors of the judgment are eccentricity value judgment, weighing value judgment and power judgment respectively. And when any two of the eccentricity value judgment, the weighing value judgment and the power judgment are true, determining that the load type of the drying load is a multi-load through comparison between the acquired eccentricity value, the weighing value and the power of the drying load and the corresponding preset multi-load eccentricity threshold value, preset multi-load weighing threshold value and preset multi-load power threshold value.

In one embodiment, as shown in fig. 6, the following step S61 is further included:

in step S61, another load determination is made as to whether or not any two of the eccentricity value determination, the weight value determination, and the power determination are false.

In one embodiment, the result of the collective operation of the multiple loads and the other loads is a full set, and there is no intersection between the multiple loads and the other loads. That is, in the case where only one and none of the judged factors in the previous embodiment are satisfied, it is confirmed that the load type of the drying load is the other load. Under the condition of other loads, the drying quality requirement of the drying load can be met without adjusting the drying aspect of the washing and drying integrated machine.

In one embodiment, fig. 7 is a block diagram illustrating a device for determining a drying load according to an exemplary embodiment. As shown in fig. 7, the drying load determination means includes a determination module 71 and a confirmation module 72.

The judging module 71 is used for judging whether the drying load in the clothes processing barrel is heavy load or not at least through two parameters of the eccentricity value, the weighing value and the power;

the confirmation module 72 is configured to consider the drying load as a multi-load only when at least two parameters among the eccentricity value, the weighing value, and the power all reach preset values.

The determination module 71 and the confirmation module 72 included in the drying load determination device are controlled to perform the method for determining the drying load as set forth in any of the above embodiments.
