Detailed ways

In order to make the above objects, technical solutions and advantages of the present invention clearer and easier to understand, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here constitute only part of the embodiments of the present invention and are only used to explain the present invention and do not constitute a limitation of the present invention. The embodiments and features of the embodiments may be combined with each other.

Referring to Figure 1, the present invention proposes a clothing care control method, which can be implemented using the steam generating device shown in Figure 2.

As shown in Figure 2, the steam generating device includes a water inlet device 3, a primary heating device 2, a secondary heating device 5, and a steam injection device 4 connected in sequence. Wherein, the primary heating device 2 is equipped with a detection device 1 for detecting the water level and/or temperature of the primary heating device 2 .

As shown in Figure 1, the clothing care control method may include the following steps.

In step S1: mode selection is made. Specifically, the corresponding clothing care mode is entered based on automatic recognition of clothing information or manual selection.

In step S2: control the water level and/or temperature of the primary heating device 2 to generate primary steam corresponding to the clothing care mode. Among them, the first-level steam includes any one or more of wet steam, dry steam, and superheated steam, so as to be able to care for the clothes with a controllable steam form in the full care cycle.

In step S3: control the heating temperature of the secondary heating device 5 to reheat and vaporize the condensed water generated by the delivery of the primary steam before being ejected from the steam injection device 4.

In one embodiment, a three-stage heating device can be built into the steam injection device 4 . The step S3 is specifically: controlling the heating temperatures of the secondary heating device 5 and the third-level heating device to reheat and vaporize the condensed water generated by the first-level steam transportation before being ejected from the steam injection device 4 .

Specifically, the current clothing recognition technologies on the market mainly include AI recognition and infrared spectrum recognition. When the clothing information is obtained through automatic identification, the clothing information may include, for example, any one or more of directly captured clothing images, clothing tags, clothing colors, and clothing brands. Alternatively, the clothing information may also include any one or more of clothing length, clothing width, clothing material, clothing dirtiness, clothing wrinkles, clothing care requirements, and clothing moisture content extracted after further identification of the clothing. item. After comprehensive matching analysis, the corresponding clothing care mode is entered.

Taking fiber wrinkle recovery as an example, in the corresponding clothing care mode, by controlling the water level and/or temperature of the primary heating device 2, primary steam corresponding to the clothing care mode can be generated. Therefore, during the entire care cycle of clothing, different forms of first-level steam can be provided for each step according to the fiber wrinkle recovery mechanism to achieve efficient care. Wet steam can be mainly used to soak, expand and stretch fiber folds in the early stage of clothing care. In the middle stage of clothing care, dry steam can penetrate fibers more effectively to fully care for clothing, and undergo phase changes on the fiber surface to release a large amount of heat. In this way, dry steam can, on the one hand, transform part of the crystalline region of the fiber into an amorphous region, which is more conducive to moisture absorption; on the other hand, it can restore the soft deformation of the fiber and restore wrinkles under the action of gravity. Finally superheated steam can Mainly used for fiber shaping, drying and sterilization in the later stages of clothing care.

For any form of steam, condensed water will be generated after being transported over a certain distance. When the condensed water is sprayed on the clothes with the high-pressure steam flow, it will cause large-area water stains on the clothes. In view of this, the inventor of the present application innovatively proposed that by controlling the heating temperature of the secondary heating device 5, the condensed water generated by the primary steam transportation can be reheated and vaporized before being ejected (hereinafter also referred to as It is a second-level steam), which can effectively avoid water spraying when steam is sprayed out.

Preferably, the clothing information may include clothing material and other aggregated information. Among them, other aggregated information is information related to clothing and non-clothing materials. Clothing care modes are divided into V1 to Vn modes based on different clothing materials. In any clothing care mode, by controlling the water level and/or temperature of the first-level heating device 2, first-level steam corresponding to other aggregated information is generated to provide differentiated care for clothes of the same type in the full care cycle. .

Specifically, the clothing care mode can first be divided into V1 to Vn modes according to different clothing materials. For example, V1 mode can correspond to linen materials, V2 mode can correspond to cotton materials, V6 mode can correspond to blended materials containing cotton and linen materials, and V7 mode can correspond to blended materials containing no cotton and linen materials. The details are shown in the table below.

In any clothing care mode, due to differences in other aggregated information, such as differences in any of the clothing materials, clothing lengths, clothing widths, clothing soiling levels, and clothing wrinkle levels, or for example, different ironing temperatures for the same materials , whether ironing is possible, etc., may cause the water level control and/or temperature control of the primary heating device 2 to be different. The resulting first-level steam also has different parameters such as steam shape, steam temperature and humidity, and steam saturation. This allows differentiated care for clothing of the same type of material throughout the care cycle based on other aggregated information.

More specifically, assuming that other aggregation information is consistent, an example of control in the form of vapor is explained below.

As shown in the table above, linen clothing can be cared for in V1 mode. Specifically, since the hemp fiber has high crystallinity and is not easy to absorb water, it is necessary to control the generation of less wet steam, and then choose to control the steam outlet time of the wet steam, for example, it can only be t1=30s; at the same time, given the large modulus of the hemp fiber, To restore the wrinkles of the hemp fiber, a higher care temperature (185~205℃) is required, and then the dry steam outlet time t2 = 30s and the superheated steam outlet time t3 = 180s need to be sequentially controlled for high-temperature care, and then given to the clothes. It takes a certain amount of time to finalize the shape and the care is completed.

If it is wool clothing, you can choose V3 mode. Specifically, because wool fiber is mainly composed of a variety of amino acids, it is afraid of high temperatures and easily absorbs water. Therefore, temperature control is the key to caring for clothing made of this material. Wet steam is mainly used for care, and the steam spray device 4 should be kept at least 3cm from the wool clothing. Care at a distance. Sequentially control the wet steam outlet time t1 = 60s, dry steam outlet time t2 = 20s, and superheated steam outlet time t3 = 15s, thereby reviving the wool and completing the care.

For another example, cotton clothing can be cared for in V2 mode. Specifically, compared with linen clothing, it is necessary to control the generation of more wet steam and more dry steam for care, because cotton fibers have more active groups on the surface and are easy to absorb water. More wet steam can make the fiber Fully softening; at the same time, given the relatively large modulus of cotton fiber, a higher temperature of 170 to 200°C is needed to restore the wrinkles of cotton fiber. Then, dry steam and superheated steam are controlled in sequence for high-temperature care, and the clothes are given a certain amount of time. Styling, care is complete.

Preferably, as one of the preferred embodiments of the present invention, as shown in Figure 3A, step S2 may include any one or more combinations of the following:

S21: When the detection device 1 detects that there is water in the primary heating device 2 and the temperature T is greater than the first preset temperature T1, the control valve of the steam injection device 4 is opened to generate wet steam. The specific operation process is shown in Figure 4A;

S22: When the detection device 1 detects that there is no water in the primary heating device 2 and the temperature T is greater than the second preset temperature T2, the control valve of the steam injection device 4 is opened to generate dry steam. The specific operation process is shown in Figure 4B;

S23: When the detection device 1 detects that there is no water in the primary heating device 2 and the temperature T is greater than the third preset temperature T3, the control valve of the steam injection device 4 is opened to generate superheated steam. The specific operation process is shown in Figure 4C.

Among them, T1<T2≤T3.

Specifically, by detecting the water level and temperature in the first-level heating device 2, a more accurate phase change judgment can be made for the temperature rise control of the care medium in the first-level heating device 2, and then a certain kind of required temperature can be generated and released as needed. Phase change steam. During the generation of steam, the water inlet of the water inlet device 3 can be controlled (the default control valve opens the previous stage heating device). Setting 2 will maintain continuous heating) to quickly control the water vapor volume and temperature rise of the care medium to meet the quality control requirements of the required phase change steam. Optionally, the control valve can also be provided on the primary heating device 2 .

Of course, it can be understood here that the first preset temperature T1, the second preset temperature T2, and the third preset temperature T3 can all be interval values. Under different clothing care modes and even different model configurations, T1 The specific values of can be different, and the same applies to T2 and T3. For example, as the lower limit values for phase change judgment, T1 can be set to [90, 100]°C, T2 to [100, 110]°C, and T3 to [120, 130]°C.

Preferably, as another preferred embodiment of the present invention, as shown in Figure 3B, step S2 may include any one or more combinations of the following:

S24: When the detection device 1 detects that the temperature rise rate V in the primary heating device 2 is less than the first preset rate V1 and the temperature T is greater than the fourth preset temperature T4, it opens the control valve of the steam injection device 4 to generate wet steam. Specific operations The process can be shown in Figure 5A;

S25: When the detection device 1 detects that the temperature rise rate V in the primary heating device 2 is greater than the second preset rate V2 and the temperature T is greater than the fifth preset temperature T5, the control valve of the steam injection device 4 is opened to generate dry steam. Specific operations The process can be shown in Figure 5B;

S26: When the detection device 1 detects that the temperature rise rate V in the primary heating device 2 is greater than the third preset rate V3 and the temperature T is greater than the sixth preset temperature T6, the control valve of the steam injection device 4 is opened to generate superheated steam. Specific operations The process can be shown in Figure 5C.

Among them, V1＜V2≤V3, T4＜T5≤T6.

Specifically, given that the temperature of steam does not increase during the process from unsaturated to wet saturated to dry saturated, if it continues to be heated after dry saturation, the temperature will rise and become superheated steam. Furthermore, compared with the first preferred embodiment mentioned above, this preferred embodiment only needs to detect the temperature in the primary heating device 2 to control the temperature rise of the care medium in the primary heating device 2 more accurately. Based on the change judgment, the required opportunity can be selected to generate and release the required phase change steam. During the steam generation, the heating rate V and temperature T can be quickly reached to the required phase change steam quality control requirements by controlling the water inlet of the water inlet device 3 (the default control valve is opened before the first-stage heating device 2 will maintain continuous heating). .

Among them, it should be noted here that for the change value of the heating rate V, the temperatures collected adjacent to each second are an arithmetic sequence. When the difference change is greater than the preset rate, it is considered that the heating rate has changed significantly. For example, when the power of the first-level heating device 2 is 1700W, the heating rate when there is water is 0.91°C/s. After the water is dried, the temperature rises sharply, and the heating rate reaches 3.8°C/s, which is an increase of 3 times. At this time, the first-level heating device 2 has a power of 1700W. Superheated steam will be obtained in the heating device 2; for another example, when the power of the first-level heating device 2 is 1300W, when there is water, the heating rate is 0.66°C/s. After the water is dried, the temperature rises sharply. The heating rate reaches 3.8°C/s, which is an increase of 5.7 times. At this time, superheated steam will be obtained in the primary heating device 2. Therefore, for example, V1≤2, V2≥2.5, and V3≥2.5 can be set, and the units are all in °C/s.

Of course, it can also be understood here that the fourth preset temperature T4, the fifth preset temperature T5, and the sixth preset temperature T6 are all interval values here. Under different clothing care modes and even different model configurations, , the specific value of T4 can be different, and the same applies to T5 and T6. For example, as the lower limit value for phase change judgment, T4 can be set to [90, 100]°C, T5 to [100, 110]°C, and T6 to [120, 130]°C.
