Description

Technical Field

[0001] This application relates to the field of washing machines, and in particular, to a steam control method and a steam control device for clothing care. Background Art

[0002] With the rapid development of the washing and care industry and the continuous improvement of the national living standards, consumers' requirements and expectations for washing and care products are no longer limited to the washing effect of clothes. Instead, more attention is paid to the care effect of some special materials of clothes, such as wool, down, silk, etc. These special and high-end materials are usually relatively fragile and will have problems such as wool shrinkage, low down fluffiness, and silk wrinkles under the mechanical action and high temperature of the washing machine. In addition, the requirements for wrinkle removal and odor removal of some clothes are also attracting more and more attention from consumers. For example, when going out for a business meeting, it is found that one's suit has obvious wrinkles; before receiving guests at home, it is found that the clothes are wrinkled and have a slovenly feeling; the musty smell of clothes during the changing of seasons, the smell of tobacco and alcohol in social occasions, etc. If clean clothes are washed again, it is time-consuming and laborious and increases the wear of the clothes. The steam care function of the washing and drying machine can easily achieve wrinkle removal and odor removal of clothes.

[0003] At present, the method of caring for clothes by a washing and drying machine is also widely used. Generally, there is only one steam nozzle in the drum. However, due to the different thicknesses of the clothes, the heights to which the clothes are brought by the lifting ribs are also different. In this way, the steam ejected from the steam nozzle cannot completely fall on the clothes, and the clothes cannot effectively absorb the steam, resulting in poor clothing care effect.

Regardless of the weight of the laundry, it can efficiently absorb steam and improve the laundry care effect. Description of the Drawings

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0026] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] The present application discloses a steam control method for clothing care, which is applied to a washing machine to improve the clothing care effect. For example Figure 1 As shown, the method includes the following steps:

[0028] Step 101: When the washing machine enters the steam ironing stage, determine the number of times the clothing contacts the clothing sensor.

[0029] Among them, the preset sensor position where the clothing sensor is located is lower than the position of the first steam nozzle, and the distance difference between the clothing sensor and the first steam nozzle is greater than the set distance. The first steam nozzle is located on the upper side wall in the drum.

[0030] The care mode of the washing machine includes a steam ironing stage and a drying care stage. In the steam ironing stage, the water in the steam water box is heated to generate steam that enters the inside of the drum. The steam penetrates into the clothes, playing the role of removing odors and wrinkles. After the clothes are evenly wetted by the steam, they enter the drying care stage. During the drying care process, high-temperature and low-humidity air is mainly produced by the air supply fan and the heat source, and this air is blown into the inner drum to increase the temperature of the clothes, thereby evaporating the moisture on the clothes and discharging the evaporated moisture out of the machine body. At the same time, with the continuous blowing of the wind by the fan and the corresponding drying temperature, the clothes wrinkles are smoothed and the flat state of the clothes is restored.

[0031] The embodiment of the present application is applied to the steam ironing stage. After the steam ironing is started, the washing machine controls the steam water box to be heated, and the water temperature in the steam water box begins to rise and generate steam. At this time, the steam does not erupt, and the washing machine controls the clothes to start to perform a parabolic motion under the action of the lifting rib.

[0032] There is a first steam nozzle in the drum of the washing machine, and the first steam nozzle is located on the upper side wall in the drum. Under normal circumstances, the steam water box and the steam generator jointly generate high-temperature steam, which enters the drum through the first steam nozzle. Under the continuous blowing of a large amount of air and in combination with the corresponding drying temperature, the clothing fibers can be softened, the clothing wrinkles can be smoothed, and the flat state of the clothing can be restored. However, the position of the first steam nozzle is set relatively high, and relatively heavy clothes may not be able to be lifted to a high position in the drum, and the hot steam is in an upward floating state, so relatively heavy clothes cannot effectively absorb the steam.

[0033] On the basis of the prior art, the present application adds a set of steam care devices and clothing sensors. The steam care devices include a second steam nozzle and a steam outlet pipe. Figure 2 Schematic diagram of the steam care equipment, from Figure 2 It can be seen that the water inlet pipe 1 is connected to the steam water box 4. The first steam nozzle 5 is arranged at a relatively high position on the side wall of the inner barrel 2. The first steam nozzle 5 is connected to the steam water box 4 through the first steam outlet pipe 7-1, and a first steam outlet valve 8-1 is provided on the first steam outlet pipe 7-1; the second steam nozzle is arranged on the side wall of the drum of the washing machine, and the position of the second steam nozzle is lower than the position of the first steam nozzle. The second steam nozzle is connected to the steam water box 4 through the second steam outlet pipe 7-2, and a second steam outlet valve 8-2 is provided on the second steam outlet pipe 7-2.

[0034] The clothing sensor 9 is set at a preset sensor position, where the preset sensor position is lower than the position of the first steam nozzle and the distance difference between them is greater than a set distance. That is to say, the position of the clothing sensor is much lower than the position of the first steam nozzle, and the position of the second steam nozzle is very close to the position of the clothing sensor. Then the position of the second steam nozzle is also much lower than the position of the first steam nozzle.

[0035] As Figure 2 shown, the second steam nozzle is set at the position of the central axis 6, and the clothing sensor is set at a position above the central axis. The clothing sensor can also be set on the observation window, but the position of the clothing sensor is higher than the position of the second steam nozzle.

[0036] During the process of the washing machine controlling the clothing to do parabolic motion through the lifting rib 3, the contact times between the clothing and the clothing sensor are determined.

[0037] Step 102: If the contact times are less than a preset number threshold, control the second steam nozzle to eject steam.

[0038] Wherein, the distance difference between the position of the second steam nozzle and the preset sensor position is less than a preset distance.

[0039] If the contact times are less than the preset number threshold, it indicates that the clothing is heavy and cannot be thrown to the position of the clothing sensor. Since the second steam nozzle is relatively close to the clothing sensor, at this time, controlling the second steam nozzle to eject steam can make the clothing come into contact with the steam and thus obtain effective care.

[0040] The principle of care is as follows: The steam enters the inside of the drum and then penetrates into the clothing, playing a role in removing odors and wrinkles; then it will enter the drying care process. During the drying care process, the drying temperature is an important operating condition index. With the change of the ambient temperature, various properties of the textile materials will change accordingly. During the care drying process, mainly by using the air supply fan and heat source to produce high-temperature and low-humidity air and blowing it into the washing tub to increase the temperature of the clothing, thus evaporating the moisture on the clothing and discharging the evaporated moisture out of the body to play a care role.

[0041] Preferably, the position of the clothing sensor is higher than the position of the second steam nozzle. Even if the clothing does not touch the clothing sensor, the clothing may still be thrown to a position level with or slightly lower than the second steam nozzle and can still get the steam ejected from the second steam nozzle.

[0042] Step 103: If the contact times are greater than or equal to the preset number threshold, control the first steam nozzle to eject steam.

[0043] If the contact times are greater than or equal to the preset number threshold, it indicates that the clothing is light and can be lifted to a higher position by the lifting rib, then control the first steam nozzle to eject steam.

[0044] In this application, a first steam nozzle with a relatively high position and a second steam nozzle with a relatively low position are additionally provided in the washing machine, and a clothing sensor is arranged near the position of the second steam nozzle. When the number of contacts between the clothing and the clothing sensor is less than the preset number threshold, it indicates that the clothing is heavy and cannot be lifted to the first steam nozzle at a relatively high position. Then, the second steam nozzle at the lower position is used to eject steam to care for the clothing. When the number of contacts between the clothing and the clothing sensor is greater than or equal to the preset number threshold, it indicates that the clothing is light and can be lifted to the first steam nozzle at a relatively high position. Then, the first steam nozzle at the higher position is used to eject steam to care for the clothing. Regardless of the weight of the clothing, steam can be efficiently absorbed, improving the clothing care effect.

[0045] In addition, when the washing machine detects that the moisture content of the clothing reaches the preset moisture content, it indicates that the steam ironing of the clothing is completed. Then, it controls the first steam nozzle or the second steam nozzle to stop ejecting steam, and then controls the washing machine to enter the drying care mode. After the drying care is completed, the entire care process ends.

[0046] Figure 3 It is a steam control flow chart for clothing care. When the care program of the washing machine is started, the washing machine performs steam electroheating according to the steam care program selected by the customer, and the clothing inside the drum rotates synchronously. During this process, the number of contacts between the clothing and the clothing sensor is calculated and recorded as A. When A≥10, the upper steam nozzle is opened to mainly spray steam on the completely thrown-open clothing to improve the steam absorption efficiency of the clothing. When A<10, the central axis nozzle is used to spray steam on the clothing that cannot be lifted to improve the steam absorption efficiency of the clothing. The washing machine selects to open the upper steam port or the central axis steam port according to the movement track of the clothing in the drum and the number of contacts to improve the steam absorption efficiency of the clothing and optimize the care.

[0047] In the prior art, when high-temperature steam enters the drum, since the position of the steam nozzle is at the front air duct position of the drum, in the early stage of steam generation, the steam nozzle directly sprays onto the observation window. Affected by the low temperature of the observation window glass, the steam is condensed into water droplets by the observation window, reducing the steam utilization rate and affecting the clothing care efficiency.

[0048] This application sets two-way steam nozzles, namely an upper steam nozzle and a central axis steam nozzle. The upper steam nozzle mainly sprays steam on the completely thrown-open and light clothing to improve the steam absorption efficiency of the clothing. The central axis nozzle mainly sprays steam on the heavy clothing that cannot be completely lifted to improve the steam absorption efficiency of the clothing.

[0049] By adding a steam nozzle to the central axis of the rotating drum and connecting the steam generator and the steam water box, during the care process, for heavy clothes that cannot be fully lifted to the upper side of the drum, the steam generated by the steam generator is directly ejected from the steam nozzle at the central axis of the drum. The clothes are lifted by the lifting ribs in the drum and can directly contact the steam at the central axis nozzle, ensuring that the clothes are evenly wetted by the steam. And because the steam is hot steam and has an upward movement trend, the drum can be quickly filled with steam, improving the efficiency of the clothes absorbing steam.
