However, these inventive concepts can be embodied in many different forms and should not be considered limited to the embodiments described herein.

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention may be combined with each other. Figure 1 The dotted line in the figure indicates electrical connection. In the present application, both dry steam and wet steam are based on relative humidity, and the steam with lower relative humidity is dry steam, and the steam with higher relative humidity is wet steam.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] In order to solve the problem that the ironing control logic of the clothing care machine in the prior art is relatively simple, and the ironing effect is poor for clothes of different fabrics, or even the clothes are burned, this embodiment proposes a control method for the clothing care machine, as shown in the attached figure. Figure 1-2 As shown, the control method includes:

[0025] S1. Obtain clothing material information, and obtain clothing care procedures according to the clothing material information;

[0026] The material information of clothing can be obtained by the user manually selecting a button or manually inputting it, or a corresponding identification device, such as a camera, can be set in the clothing care machine to obtain the material of clothing by collecting clothing images. In view of the acquisition of clothing material information, there are various acquisition methods in the existing clothing processing field, which will not be elaborated in this application.

[0027] The clothing care program in this application is mainly aimed at different clothing materials. The clothing care machine obtains clothing care machine control parameters corresponding to the clothing materials. This control parameter at least includes relevant parameters of the clothing care machine during the ironing process, which can be obtained from its own memory or cloud server.

[0028] S2, real-time detection of the internal pressure P and heating temperature M of the steam generator, and real-time detection of the ironing plate temperature N;

[0029] S3, determine whether P, M, and N meet the first condition; if so, proceed to step S4; if not, return to step S2;

[0030] S4, performing a wet steam ironing process on the clothes;

[0031] S5, after the wet steam ironing process is completed, increasing the temperature N of the ironing plate until N meets the second condition;

[0032] S6, performing a dry steam ironing process on the clothes;

[0033] S7. Dry clothes.

[0034] The first condition is that P reaches the target pressure range, M reaches the first temperature range, and N reaches the second temperature range. The second condition is that N reaches the third temperature range. The clothing care program at least includes the target pressure range, the first temperature range, the second temperature range, and the third temperature range corresponding to each clothing material, and also includes the drying parameters during the clothing drying process.

[0035] Therefore, according to the material of the clothes, the present application enables the steam generator to provide steam in a specific state and the ironing plate to be in a specific temperature state. First, the clothes are wet-steam ironed with high-temperature wet steam to fully soften the clothing fibers. Then, the temperature of the ironing plate is increased and the clothes are dry-steam ironed with high-temperature dry steam. The clothes are subjected to two-stage ironing treatment, which is beneficial to improving the clothing care effect on the one hand, and on the other hand, can provide ironing that meets the material requirements of the clothes for clothes of different materials, thereby preventing the occurrence of insufficient ironing of clothes or damage to the clothes.

[0036] Specifically, the present application proposes several correspondences between fabric materials and clothing care procedures as examples.

[0037]

[0038] The wet steam ironing process includes: opening the steam valve at a first opening, delivering the steam generated by the steam generator to the ironing board assembly, spraying the steam onto the clothes through the ironing board assembly, ironing the clothes with the ironing board, and closing the steam valve after the clothes are ironed.

[0039] The dry steam ironing process includes: opening the steam valve at a second opening, delivering the steam generated by the steam generator to the ironing board assembly, spraying the steam onto the clothes through the ironing board assembly, ironing the clothes with the ironing board, and closing the steam valve after the clothes are ironed. The second opening is ≤ the first opening.

[0040] Therefore, in the present application, when the wet steam ironing is performed, the temperature of the ironing board is low and the steam supply is large, so that the relative humidity of the steam sprayed from the ironing board assembly is large, and the high temperature and high humidity steam is used to fully soften the clothing fibers; in the dry steam ironing, the temperature of the ironing board is high and the steam supply is small, so that the relative humidity of the steam sprayed from the ironing board assembly is small, and the clothes are ironed twice with higher temperature but relatively low humidity steam to improve the clothing care effect. Among them, the opening size of the steam valve can be adjusted by the opening percentage of the valve, such as 100% means that the valve is fully open, and 0% means that the valve is closed. In the present application, the first opening can be 90%-100%, and the second opening is 85%-95% of the first opening.

[0041] In the present invention, for any clothing care machine with an ironing function, the control method of the clothing care machine described in this embodiment can be adopted. The clothing care machine comprises:

[0042] A steam generator for generating steam;

[0043] An ironing device, connected to the steam generator through a steam pipeline, for heating the steam generated by the steam generator and ironing the clothes;

[0044] A steam valve is arranged in the steam pipeline between the ironing device and the steam generator, and is used to control the on-off condition of the steam generator supplying steam to the ironing device;

[0045] The control system is connected with the steam generator, ironing device and steam valve by electrical signals and is used to control each component to work according to the set parameters.

[0046] The ironing device comprises an ironing board assembly and a heater, wherein the heater is connected to the ironing board assembly and is used to heat the ironing board and the steam delivered to the ironing device. Similarly, the heater and the ironing board assembly are both connected to the control system through electrical signals.

[0047] The steam generator is provided with a first temperature sensor and a pressure sensor (not shown) for respectively collecting the heating temperature in the steam generator and the internal steam pressure of the steam generator. The ironing device is provided with a second temperature sensor for collecting the temperature of the ironing board. Accordingly, the first temperature sensor, the pressure sensor and the second temperature sensor are connected to the control system through electrical signals.

[0048] The steam generator is provided with a first thermostat, which is connected to the steam generator and the control system by electrical signals, and is used to control the steam generator to stop heating when the heating temperature of the steam generator exceeds the first temperature limit. The ironing device is provided with a second thermostat, which is connected to the ironing device and the control system by electrical signals, and is used to control the ironing device to stop heating when the heating temperature of the ironing device exceeds the second temperature limit. The first temperature limit and the second temperature limit are both preset values ​​under the safe operation conditions of the electrical appliance. In view of the fact that the performance and safety level of electrical appliances of different manufacturers are often different, this application does not make specific restrictions on the corresponding preset values, and only provides individual examples for reference, such as: the first temperature limit is about 230℃-240℃, and the second temperature limit is about 200℃-220℃.

[0049] In addition, the clothing care machine also has a drying function. Specifically, the clothing care machine includes an air drying device that can deliver air to the clothes to dry the clothes. The air drying device is provided with a heating device for heating the air flow, and the clothes are dried by delivering high-temperature air to the clothes. The air drying device is connected to the control system by electrical signals.

[0050] In order to improve the degree of automation of the drying process, the clothing care machine includes an image acquisition device, which performs grid acquisition of the image information of the clothing, specifically, the clothing image is divided into a plurality of acquisition grids, and the image information in each acquisition grid is acquired, and the image information includes at least any one of the grayscale, contrast, saturation or color of the image. In the present application, the image information acquired by the image acquisition device is preferably a conventional 256-level grayscale. The image acquisition device is connected to the control system by electrical signals.

[0051] Step S7 includes:

[0052] S71, the air drying device dries the clothes;

[0053] The clothing care program acquired in step S1 includes drying parameters corresponding to the clothing material, such as drying temperature, drying time, etc.

[0054] S72, the image acquisition device acquires image information of the clothes in the drying process in real time;

[0055] S73, obtaining the gray level K in the image information in any acquisition grid, and for any acquisition grid, calculating the absolute value N of the level change of K in unit time;

[0056] Among them, the unit time is often a preset value, and each clothing washing machine manufacturer can set it according to its own research and development situation. This application does not impose too many restrictions on it, and only gives a simple example. For example: the unit time in this application can be 15 seconds-90 seconds. In addition, N = |K at the current moment-K at the corresponding moment before the unit time|, the calculation of the absolute value of this change conforms to the conventional mathematical meaning and will not be repeated.

[0057] S74, determining whether N of all collection grids is ≤ the preset level, if so, determining that the clothes are dried; if not, returning to step S72.

[0058] The preset levels are preset values, and each clothing washing machine manufacturer can set them according to their own research and development conditions. This application does not impose too many restrictions on them, and only gives a simple example. For example: the preset levels in this application are level 1-level 2.

[0059] Therefore, the present application collects clothing image information in real time during the clothing drying process through steps S71-S74, analyzes and processes the changes in the grayscale level K, and determines that the target drying effect is achieved when the grayscale level remains unchanged for a certain period of time, or the change range is very small. This is beneficial to improving the accuracy of drying effect judgment, improving the drying efficiency of the clothing washing machine, and stopping drying of the already dried clothes in time to facilitate subsequent actions or promptly reminding the user to take out the clothes.

[0060] In addition, the clothing care machine also includes conventional components including a shell, a driving mechanism and other structures. Since the existing technology can be adopted, they will not be described in detail here.

[0061] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
