[0002] The front-loading washing machine was invented in Germany and became popular in Europe. Now, it has gradually become the type of washing machine favored by consumers worldwide.

[0003] The principle of a drum washing machine is to use the mechanical work of an electric motor to make the drum rotate. The clothes are constantly lifted and dropped in the drum, and then lifted and dropped again, repeating the motion. With the combined action of detergent and water, the clothes are cleaned.

[0004] Currently, drum washing machines on the market produce a lot of noise when washing single items or small amounts of clothing.

[0045] The technical solutions of the embodiments of the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0046] Figure 1 This diagram illustrates a flow chart of a washing control method for a drum washing machine according to an embodiment of the present invention. This embodiment is applicable to situations where a drum washing machine is used to wash a small amount of clothing (no more than three pieces). The method can be executed by a washing control device configured in the electronic equipment of the washing machine, such as... Figure 1 As shown, the washing control method of the drum washing machine described in this embodiment includes:

[0047] In step S110, the dry weight of the washed clothes is obtained.

[0048] For example, the dry weight of the laundry can be obtained from the user's input. Alternatively, the dry weight of the laundry can be obtained before washing using a weight sensor built into the drum washing machine. Another example is that after the laundry is placed in the washing machine and the start button is pressed, the inner drum can be rotated before water enters to obtain its balance, and the dry weight of the laundry can be determined based on the obtained balance.

[0049] In step S120, the water level frequency of the washing stage is determined.

[0050] For example, a fixed water level frequency can be set for washing a small amount of clothes (no more than three pieces). According to the results of comparative experiments, the water level frequency in the washing stage can achieve the effect of cleaning clothes with the least noise when it is in the range of greater than 3850 and less than 3950.

[0051] In step S130, the washing speed corresponding to the dry clothes weight and the water level frequency is determined according to the set mapping relationship, wherein the set mapping relationship is used to make the clothes being washed drop off at a position away from the highest point to reduce noise.

[0052] For example, the defined mapping relationship may include a defined functional relationship between dry clothes weight, water level frequency, and spin speed, and the washing spin speed corresponding to the dry clothes weight and the water level frequency can be determined according to the defined functional relationship. Alternatively, the washing spin speed corresponding to the dry clothes weight and the water level frequency can be found in a mapping table corresponding to the defined mapping relationship.

[0053] According to the results of the comparative experiment, the preferred mapping relationship is that when the line connecting the starting position of the clothes being washed and the center of the drum forms a 30-degree angle with the horizontal line, the clothes can be washed clean and the noise during the washing process is small. According to the results of the comparative experiment, the noise is minimized when the washing speed of the washing machine is in the range of 60 to 70 revolutions per minute, while still ensuring that the clothes are washed clean.

[0054] In step S140, the inner tub of the drum washing machine is rotated according to the washing speed. That is, the current value of the drum washing machine is adjusted to control the inner tub to rotate at the washing speed.

[0055] It should be noted that, in order to achieve better washing results, existing drum washing machines, when designing their washing control methods, will control the clothes to be washed from the highest point possible (e.g., ...). Figure 2 Drop the object at point A (as shown) to maximize the tumbling intensity and enhance the washing effect.

[0056] This washing control method is suitable for washing multiple garments. When the garments fall, there are other clothes at the point of impact. On the one hand, this can reduce some of the impact force, and the sound of the garments hitting the water and the bottom of the inner drum can be partially blocked and reduced. On the other hand, the presence of clothes at the point of impact also shortens the distance the garments fall. Therefore, the noise during the washing process is not obvious.

[0057] For washing single items or small quantities of clothing, the clothes should be placed from the highest point (e.g., ...). Figure 2 After the clothes fall (as shown at point A), there are often no clothes to block them at the point of impact. The clothes will rush to the surface of the water and then directly hit the bottom of the inner drum, which will make the noise very obvious. This is why users often feel that the noise of washing a single piece of clothing is much louder than the noise of washing multiple pieces of clothing.

[0058] Because the spin speed of a front-loading washing machine directly affects the position of the clothes when they are tumbled down, current washing machine programs are set with a fixed spin speed to control the clothes to be tumbled from the highest point possible (e.g., ...). Figure 2 The clothes are dropped from point A (as shown) to maximize the tumbling intensity and enhance the washing effect. This fixed spin speed is the standard spin speed for this model of washing machine and cannot be adjusted by the user. The size and specifications of the washing machine may affect the spin speed at which the clothes are dropped from the highest point, resulting in slight differences in the fixed spin speed during the washing stage for different types of washing machines, but most are concentrated in the range of 45 to 50 revolutions per minute.

[0059] This embodiment considers that when washing a single garment or a small number of garments, there are no clothes underneath to obstruct the fall, resulting in a longer fall distance and a larger water contact area compared to washing multiple garments. Therefore, slightly reducing the fall distance would not significantly affect the washing effect of a single garment. This embodiment discloses a new washing control method. Compared to existing washing control methods that use a speed of 45 to 50 revolutions per minute, this embodiment determines the washing speed corresponding to the current dry weight and water level frequency based on a set mapping relationship. Compared to existing drum washing machine control methods, this increases the speed during the washing stage, enabling the washing clothes in the drum washing machine to fall from a position away from the highest point rather than at the highest point (e.g., ...). Figure 3(Point B shown) is used to reduce the distance the clothes travel during the fall, thereby reducing noise. Compared to existing drum washing machine control methods that aim to determine the spin speed so that the clothes fall at the highest point, the control method described in this embodiment overcomes the technical bias of existing drum washing machine control methods in determining the spin speed. When washing a single item or a small amount of clothing, it can control the spin speed during the washing stage so that the clothes fall at a position away from the highest point, thereby reducing noise and reducing noise while still ensuring the clothes are clean.

[0060] Furthermore, in this embodiment, when determining the water level frequency during the washing stage in step S210, a water level frequency lower than that set by the inherent control method of existing drum washing machines can be adopted to raise the water level during the washing process. On the one hand, this can shorten the distance the washed clothes fall, thus reducing noise; on the other hand, it can increase the water surface area. The increased water surface area allows the washed clothes to have a larger contact area with the water after falling, thereby increasing the friction of the water mixed with detergent on the clothes and improving the washing effect.

[0061] Figure 2 H1 is a schematic diagram showing the height at which clothes fall, corresponding to the existing washing control methods of drum washing machines. Figure 3 A schematic diagram of the clothes falling height corresponding to the washing control method of a drum washing machine according to an embodiment of the present invention is shown in Figure H2. Figure 2 and Figure 3 In this context, L1 represents the water level corresponding to the existing control method, and L2 represents the water level corresponding to the control method of this embodiment. (Comparison) Figure 2 and Figure 3 It can be seen that, in terms of washing effect, compared with washing a single garment using traditional washing control methods, the starting point of the garment being tumbled during the washing process is lower, and the increased water level further shortens the distance the garment is tumbled, reducing noise. Although this weakens the tumbling effect, the increased rotation speed leads to more tumbling cycles per unit time, thus improving the washing effect to some extent. While the reduced water level frequency shortens the distance the garment travels after tumbling, weakening the tumbling force, the increased water surface area increases the contact area between the garment and water, thus balancing and improving the washing effect. Therefore, overall, the washing effect is not significantly reduced, but the noise during the washing process is decreased.

[0062] The washing control method of the drum washing machine described in this embodiment, after obtaining the dry weight of the clothes to be washed and determining the water level frequency of the washing stage, determines the washing speed corresponding to the dry weight and the water level frequency according to a set mapping relationship to control the rotation of the inner drum. The set mapping relationship is used to make the clothes to be washed fall off at a position away from the highest point to reduce noise, which can solve the technical problem of excessive noise when washing a small amount of clothes in existing drum washing machines.
