Detailed Description

In order to make the objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.

FIG. 1 is a general flow diagram of a method 100 for washing laundry in an embodiment of the present invention; fig. 2 is a detailed flowchart 200 of washing laundry in an embodiment of the present invention, wherein the second heating washing pattern includes a sub-pattern.

The method 100 includes detecting a load mass dropped into the laundry treating apparatus (S110), determining whether the load mass is greater than a first threshold (S120), and if so, performing a first heating washing pattern (S130), and if not, performing a second heating washing pattern (S140). The laundry treating apparatus may include a rotatable drum to receive a load and an outer drum to be sleeved outside the drum.

In the execution of step S110, the mass of the load dropped into the laundry treating apparatus is detected. Detecting the load mass is a conventional means in the art, for example, calculating the mass of the load by detecting a signal from the motor (e.g., a signal from the power consumed to drive the load).

In the execution of step S120, it is determined whether the load quality is greater than a first threshold. In one embodiment, the first threshold is in a range of greater than or equal to 3 kilograms and less than or equal to 6 kilograms. In another embodiment, the ratio of the first threshold to the rated capacity of the laundry treating apparatus is in the range of greater than or equal to 30% and less than or equal to 60%; wherein the rated capacity is a quality of dry laundry that the laundry treating apparatus can wash maximally.

In the execution of step S130, the first heating and washing manner is operated. The first heating washing manner may be a conventional washing heating manner, that is, a manner of heating the load and the free water through a washing heating pipe in the water in a state that the free water is provided in the outer tub and the load is in contact with the free water, and then washing. Wherein, the free water is water which flows freely in the inner cylinder or the outer cylinder of the clothes treatment equipment.

In the execution of step S140, the second heating and washing manner is operated. The second heating washing method may be a steam-heating washing method, that is, a method of heating the wetted load by hot air in a state where free water is not present in the outer tube, followed by washing.

According to the technical scheme of the embodiment of the invention, the first heating washing mode or the second heating washing mode can be selectively executed according to the comparison between the detected load mass and the first threshold value, wherein the first heating washing mode can be a traditional washing heating mode, and the second heating washing mode can be a steam heating washing mode. For example, when the detected load mass is less than or equal to the first threshold, automatically switching to a steam-heat washing mode with higher heating efficiency, namely, only the fully wetted load is heated by hot air, redundant free water is not heated, and the state without free water is kept in the subsequent washing process, so that the wet-heat load is fully contacted with the inner cylinder and beaten, and the heating washing process is completed more efficiently; for the condition that the detected load mass is larger than the first threshold value, the traditional washing heating mode is still used, so that the washing effect is ensured. The two heating washing modes are automatically switched according to the load quality, so that a more efficient mode is always adopted for washing, the washing performance is improved, and the energy consumption and the time are saved.

The traditional washing heating mode has simple mechanical structure design, mature technology and simple control program, and is a washing mode commonly adopted by almost all drum washing machines at present. However, when washing a relatively small amount of load (for example, a load having a washing mass less than or equal to the first threshold), if the conventional washing heating manner is adopted, in the case where the temperature is heated to be high (for example, above 80 degrees celsius), the energy consumption for heating is large and the washing time is long; if the steam hot washing mode described in the embodiment of the invention is adopted, the higher the temperature (for example, above 80 ℃), the more energy consumption and the washing time can be saved.

For a standard cotton load of 3 kilograms and a washing scene with an ultrahigh temperature of 90 ℃, experiments show that compared with the traditional washing and heating mode, the steam-hot washing mode still improves the washing performance (washing ratio) by 5% on the basis of saving 30% of washing energy consumption and 12% of washing time.

For various load qualities, the same existing design of draining, dewatering and rinsing can be used after the washing process is finished, and a drying phase can also be included.

Performing the first heating washing manner S130 may include supplying water having a first capacity into the laundry treating apparatus; this first volume of water may be obtained on a load mass basis, for example 7 litres, which is used to wash laundry powder or wash liquor.

Performing the first heating washing pattern S130 may include replenishing water, for example, by a conventional pressure value or water level control method, until the load is completely wetted; and, free water in contact with the load is formed in the outer tub. Wherein, the conventional pressure value control method is to control the pressure value within the range of 300-900Pa (pascal), for example; the water level control method is the most adopted method in the traditional washing program at present, namely, the pressure value in the control barrel is fixed (for example, maintained at 300pa) and the water level height in the barrel is always kept not to be reduced (for example, 10cm), when the load absorbs water to cause the water level height to be reduced, the water inlet valve is automatically opened to replenish water, so that the water level height is not reduced, the water which can be absorbed by the load is always ensured, after a certain time, the load is completely wetted and does not continuously absorb water, the water level height is not reduced, and the water inlet valve is not opened to replenish water.

Performing the first heating washing manner S130 may include always maintaining a certain amount of free water, and heating the free water by the washing heating pipe to heat the load.

The performing of the first heating washing manner S130 may further include a washing load. During the washing process, a certain amount of free water is always kept through water level control.

Performing the second heating and washing pattern S140 may include supplying water into the outer tub and the inner tub and sufficiently wetting the load. For example, water having a second capacity is provided into the laundry treating apparatus; this second volume of water may be obtained on a load mass basis, for example 4 to 5 litres, which is used to wash the washing powder or laundry detergent.

Performing the second heating and washing pattern S140 may include increasing the rotation speed of the drum to the first rotation speed to form a load ring, and turning on a circulation pump to spray water onto the load ring to wet the load. The first rotational speed is the lowest rotational speed at which the load is kept in a centrifugal state, wherein the first rotational speed should not be too high, so that as little water as possible is thrown out of the load, i.e. as much water as possible is kept in the load. In one embodiment, the first rotational speed is in a range greater than or equal to 130 revolutions per minute and less than or equal to 600 revolutions per minute. Forming the load ring may enable sufficient wetting of the load inside the load stack and near the rear wall portion of the inner barrel.

Performing the second heating washing pattern S140 may include determining whether the load is sufficiently wetted, and if not, replenishing water and repeating the above spraying and determining steps until the load is fully wetted. For example, the water replenishing is controlled by detecting the pressure value to judge whether the load is sufficiently wetted or not until the load is fully wetted.

Performing the second heating washing pattern S140 may include discharging the free water in the tub after the load is completely wetted.

Performing the second heating washing pattern S140 may include heating the wetted load by hot wind. In one embodiment, the air is heated by turning on an air heating pipe, the hot air is formed by turning on a fan to flow the heated air, and the hot air is passed through and heats the load. The air heating duct may be located within a drying tunnel of the laundry treating apparatus.

The performing of the second heating and washing manner S140 may further include a washing load. And in the washing process, stopping water supplementing, and washing the wetted load all the time.

In some embodiments, performing the second heating washing pattern S140 includes determining whether the load mass is less than or equal to a second threshold, and if so, performing a sub-pattern, wherein the second threshold is less than the first threshold. In one embodiment, the second threshold is in a range of greater than or equal to 1 kilogram and less than or equal to 3 kilograms. In another embodiment, the ratio of the second threshold to the rated capacity of the laundry treating apparatus is in the range of greater than or equal to 10% and less than or equal to 30%; wherein the rated capacity is a quality of dry laundry that the laundry treating apparatus can wash maximally.

Performing the sub-mode may include providing water having a third capacity into the laundry treating apparatus. This third volume of water may be obtained on a load mass basis, for example 4 litres, which is used to wash laundry powder or wash liquor.

Performing the sub-mode may include increasing the rotational speed of the drum to a second rotational speed less than the centrifugal rotational speed, turning on the circulation pump to spray water onto the load to wet the load. The centrifugal rotation speed is the lowest rotation speed at which the load is kept in a centrifugal state. In one embodiment, the second speed is in a range less than or equal to 50 revolutions per minute.

Executing the sub-mode may include determining whether the load is sufficiently wetted, and if not, replenishing water and repeating the above spraying and determining steps until the load is fully wetted. For example, the water replenishing is controlled by detecting the pressure value to judge whether the load is sufficiently wetted or not until the load is fully wetted.

Performing the sub-mode may include turning on a drain pump to drain free water in the tub after the load is fully wetted. Wherein, the free water is water which flows freely in the inner cylinder or the outer cylinder of the clothes treatment equipment.

Fig. 4 is a flowchart of a method 400 for washing laundry using a steam hot washing mode according to an embodiment of the present invention.

The method 400 includes providing water having a certain volume into the laundry treating apparatus (S410), increasing the rotation speed of the drum to a certain rotation speed (S420), turning on the circulation pump to spray water onto the load within the laundry treating apparatus to wet the load (S430), determining whether the load is sufficiently wetted (S440), supplementing water if not, and repeating the step S430 until the load is fully wetted, draining free water if it is (S450), turning on the air heating pipe to heat air (S460), turning on the fan to flow the heated air to form hot air, and passing the hot air through and heating the load (S470), and washing the load (S480).

The technical scheme of the embodiment of the invention can be based on a steam hot washing mode. When the clothes are washed by the mode, the hot air only heats the fully wetted load and does not heat redundant free water, and the free water-free state is kept in the subsequent washing process, so that the damp and hot load is fully contacted and beaten with the inner cylinder, and the heating and washing process is more efficiently finished. Moreover, when the steam hot washing mode described in the embodiment of the present invention is adopted, the higher the temperature (for example, above 80 ℃), the more energy consumption can be saved, and the more washing time can be saved.

The load mass may be detected before the water having a certain volume is supplied into the laundry treating apparatus S410, and it is determined whether the load mass is greater than a limit value, and if so, the first sub-mode is performed, and if not, the second sub-mode is performed. In one embodiment, the limit is in a range of greater than or equal to 1 kilogram and less than or equal to 3 kilograms. In another embodiment, the ratio of the limit value to the rated capacity of the laundry treating apparatus is in the range of greater than or equal to 10% and less than or equal to 30%; wherein the rated capacity is a quality of dry laundry that the laundry treating apparatus can wash maximally. Detecting the load mass is a conventional means in the art, for example, calculating the mass of the load by detecting a signal from the motor (e.g., a signal from the power consumed to drive the load).

According to the technical scheme of the embodiment of the invention, the first sub-mode or the second sub-mode can be selectively executed according to the comparison between the detected load quality and the limit value, so that the energy consumption and the time can be more effectively saved.

For various load qualities, the same existing design of draining, dewatering and rinsing can be used after the washing process is finished, and a drying phase can also be included.

Performing the first sub-mode may comprise providing the laundry treatment apparatus with a first volume of water, which may be obtained on the basis of load mass, for example 5 liters, for washing a washing powder or a laundry detergent.

Performing the first sub-mode may include increasing a rotational speed of the inner drum to a first rotational speed to form a load ring, and turning on a circulation pump to spray water onto the load ring to wet the load. The first rotational speed is the lowest rotational speed at which the load reaches and remains centrifuged to form the load ring, wherein the first rotational speed is not too high so that as little water as possible is thrown out of the load, i.e. as much water as possible is kept in the load. In one embodiment, the first rotational speed is in a range greater than or equal to 130 revolutions per minute and less than or equal to 600 revolutions per minute. Forming the load ring may enable sufficient wetting of the load inside the load stack and near the rear wall portion of the inner barrel.

Performing the first sub-mode may include determining whether the load is sufficiently wetted, and if not, replenishing water and repeating the above spraying and determining steps until the load is fully wetted. For example, the water replenishing is controlled by detecting the pressure value to judge whether the load is sufficiently wetted or not until the load is fully wetted.

Performing the first sub-mode may include draining the free water after the load is fully wetted, e.g., turning on a drain pump to drain the free water in the tub.

Performing the first sub-mode may include turning on an air heating duct to heat air, turning on a fan to flow the heated air to form hot air, and passing the hot air over and heating a load. The air heating duct may be located within a drying tunnel of the laundry treating apparatus.

The performing of the first sub-mode may further include washing the load. And in the washing process, stopping water supplementing, and washing the wetted load all the time.

The second sub-mode includes providing a second volume of water into the laundry treating apparatus. This second volume of water may be obtained on a load mass basis, for example 4 litres, which is used to wash laundry powder or liquid laundry detergent.

And executing the second sub-mode comprises increasing the rotating speed of the inner barrel to a second rotating speed which is less than the centrifugal rotating speed, and starting the circulating pump to spray water on the load so as to wet the load. The centrifugal rotation speed is the lowest rotation speed at which the load is kept in a centrifugal state. In one embodiment, the second speed is in a range less than or equal to 50 revolutions per minute. Since the load mass in the second sub-mode is relatively small, the problem of the load wrapped inside not being able to contact water generally does not occur, and therefore it may not be necessary to form a load ring.

And executing a second sub-mode, namely judging whether the load is fully wetted, and if not, replenishing water and repeating the steps of spraying and judging until the load is fully wetted. For example, the water replenishing is controlled by detecting the pressure value to judge whether the load is sufficiently wetted or not until the load is fully wetted.

The second sub-mode is performed including turning on the drain pump to drain the free water, for example, turning on the drain pump to drain the free water in the outer tub.

The second sub-mode is performed including turning on the air heating duct to heat the air, turning on the blower to flow the heated air to form hot air, and passing the hot air over and heating the load. The air heating duct may be located within a drying tunnel of the laundry treating apparatus.

Performing the second sub-mode may further include washing the load. And in the washing process, stopping water supplementing, and washing the wetted load all the time.

Another computer-readable storage medium is disclosed, which is a non-volatile storage medium or a non-transitory storage medium, and has stored thereon computer instructions, which, when executed, perform the steps of the method described above with reference to fig. 4.

In another embodiment of the present invention, there is disclosed another clothes treating apparatus 500, as shown in fig. 5, comprising an inner drum 503 for accommodating a load 502 and an outer drum 504 sleeved outside the inner drum 503 and in fluid communication with the inner drum 503 in a housing 501 thereof, a washing heating pipe 505 at the bottom of the outer drum 504 adapted to heat free water in the outer drum 504, a circulating pump 506 adapted to circularly spray water from the bottom of the outer drum 504 onto the load 502 (e.g. through a water circulating passage 507), an air heating pipe 508 located in a drying passage 509 adapted to heat air, and a blower 510 adapted to flow the heated air to form hot air and to pass the hot air through and heat the load 502.

The laundry treating apparatus 500 further comprises a control device 511 comprising a memory and a processor, the memory having stored thereon computer instructions executable on the processor, the processor when executing the computer instructions performing the steps of the method as described above in connection with fig. 4.

The laundry treating apparatus 500 may further include a pressure sensor 512, a cartridge 513, and a drain pump 516.
