Description
Technical Field
[0001] The present invention relates to the technical field of clothing care, and particularly provides a clothing care machine and a control method thereof. Background Art
[0002] A clothing care machine is a cabinet-type device integrating functions such as clothing care, shaping and wrinkle removal, and drying treatment. The clothes are hung in the care machine, which can avoid clothes wrinkles and facilitate care. As a commonly used household appliance in daily life, the clothing care machine brings great convenience to people's lives.
[0003] When drying clothes, it is necessary to determine whether the clothes have been dried. In the existing clothing care machines, the detection values obtained by temperature sensors, humidity sensors, etc. arranged in the air duct, air inlet and outlet, and the cabinet are usually used to infer whether the clothes have been dried. However, this detection method cannot directly detect whether the surface and inside of the clothes have really been dried, resulting in inaccurate drying judgment results, and also causing the drying program to stop prematurely. Eventually, the clothes cannot be dried completely, and the user experience is poor.
[0004] Correspondingly, there is a need in the art for a new clothing care machine and a control method thereof to solve the above problems. Summary of the Invention
[0005] The present invention aims to solve the above technical problems, that is, to solve the problem that the result of judging whether the clothes have been dried is not accurate enough when the existing clothing care machine dries the clothes.
[0006] The present invention provides a clothing care machine, which includes: a care cavity, in which a first electrode and a second electrode are provided; a hanging device for hanging clothes, which is arranged between the first electrode and the second electrode; a detection unit that can detect the capacitance between the first electrode and the second electrode, so that the control unit of the clothing care machine obtains the capacitance.
[0007] In the case of adopting the above technical solution, the first electrode and the second electrode form a capacitor. The clothes hung on the hanging device are between the first electrode and the second electrode and are part of the dielectric. The greater the humidity of the clothes, the greater the dielectric constant, resulting in an increase in capacitance. By detecting the capacitance between the first electrode and the second electrode by the detection unit, the control unit obtains the capacitance and calculates the humidity value according to the capacitance. Since the clothes are part of the dielectric, the humidity of the clothes themselves can be directly detected, improving the accuracy of the result of judging whether the clothes have been dried.
[0008] In the specific implementation manner of the above-mentioned clothing care machine, a conductive structure is provided on the hanging device, and the conductive structure and the clothing hung on the hanging device form an induction electrode, and the detection unit can detect the capacitance between any two of the electrodes.
[0009] In the case of adopting the above technical solution, the clothing and the hanging device are used as induction electrodes, and the capacitance between any two electrodes is detected, such as the capacitance between induction electrodes, between an induction electrode and a first electrode, between an induction electrode and a second electrode, and between the first electrode and the second electrode. The humidity value between the corresponding electrodes can be obtained through each capacitance. The area between the first electrode and the second electrode can be divided into multiple parts, and each part contains different areas of a piece of clothing, so that the humidity inside the clothing can be detected more accurately. When there are multiple pieces of clothing, each part can also contain different pieces of clothing to detect the humidity between the clothes, avoiding the inaccurate detection of the humidity of the clothes in the middle position of multiple pieces of clothing, and further improving the accuracy of the drying judgment result.
[0010] In the specific implementation manner of the above-mentioned clothing care machine, the hanging device is arranged such that the clothing hung on it is not perpendicular to both the first electrode and the second electrode.
[0011] In the case of adopting the above technical solution, when the clothing is not perpendicular to the first electrode and the second electrode, the area of the clothing to be detected can be increased, thereby improving the humidity detection effect and ultimately improving the accuracy of the drying judgment result.
[0012] In the specific implementation manner of the above-mentioned clothing care machine, at least two hanging devices are provided, and the hanging devices are arranged in a row along the direction from the first electrode to the second electrode.
[0013] In the case of adopting the above technical solution, when at least two hanging devices are provided, the hanging devices are arranged in a row along the direction from the first electrode to the second electrode, so that the induction electrode can divide the area between the first electrode and the second electrode into multiple parts, and obtain multiple capacitances and multiple humidity values. The drying situation of the clothing is judged according to the multiple humidity values, and the drying judgment can be made more accurately, improving the accuracy of the drying judgment result.
[0014] In the specific implementation manner of the above-mentioned clothing care machine, the clothing care machine further includes a cabinet body and a door body, the care cavity is surrounded by the cabinet body and the door body, and the first electrode and the second electrode are arranged on opposite side walls of the cabinet body.
[0015] In the case of adopting the above technical solution, the first electrode and the second electrode are arranged on opposite side walls of the cabinet body, which facilitates the arrangement of the first electrode and the second electrode.
[0016] In the specific embodiments of the above-mentioned clothing care machine, the first electrode is insulated from the cabinet body; and / or the second electrode is insulated from the cabinet body.
[0017] In the case of adopting the above technical solution, the first electrode and the second electrode are insulated from each other, so as to use the clothing as a dielectric to detect the humidity of the clothing and improve the accuracy of dryness judgment.
[0018] In the specific embodiments of the above-mentioned clothing care machine, a third electrode is provided on the door body, a fourth electrode is provided on the inner wall of the cabinet body on the opposite side of the door body, and the detection unit can also detect the capacitance between the third electrode and the fourth electrode.
[0019] In the case of adopting the above technical solution, the capacitance between the first electrode and the second electrode, or the capacitance between the third electrode and the fourth electrode can be detected according to the use requirements, so as to achieve a better humidity detection effect.
[0020] In a second aspect, the present invention also provides a control method for a clothing care machine. The clothing care machine includes: a care cavity, in which a first electrode and a second electrode are provided; a hanging device for hanging clothes, the hanging device is arranged between the first electrode and the second electrode, and a conductive structure is provided on the hanging device, and the conductive structure and the clothes hanging on the hanging device form an induction electrode; a detection unit that can detect the capacitance between every two adjacent electrodes, so that the control unit of the clothing care machine obtains the capacitance; the control method includes: obtaining the capacitance between every two adjacent electrodes; obtaining the humidity value between every two adjacent electrodes according to the capacitance; based on each humidity value, judging whether the clothes are dried completely.
[0021] In the case of adopting the above technical solution, by obtaining the capacitance between every two adjacent electrodes to obtain the corresponding humidity value, the humidity value inside the clothes can be detected. When there are multiple pieces of clothes, the humidity value of the clothes in the middle position of multiple pieces of clothes can also be detected. Based on each humidity value, it is judged whether the clothes are dried completely, which improves the accuracy of clothes dryness judgment.
[0022] In the specific embodiments of the control method of the above-mentioned clothing care machine, the step of "based on each humidity value, judging whether the clothes are dried completely" further includes: comparing the magnitudes of each humidity value to obtain the maximum humidity value; comparing the maximum humidity value with a preset standard humidity value; based on the comparison result, judging whether the clothes are dried completely.
[0023] In the case of adopting the above technical solution, the maximum humidity value is selected from the humidity values corresponding to multiple parts and compared with the preset standard humidity value, which is the determination criterion for drying clothes, so as to realize the determination of whether the clothes are dried.
[0024] In the specific implementation manner of the control method of the above-mentioned clothes care machine, the step of "judging whether the clothes are dried based on the comparison result" further includes: if the maximum humidity value is less than or equal to the standard humidity value, it is determined that the clothes are dried.
[0025] In the case of adopting the above technical solution, if the maximum humidity value is less than or equal to the standard humidity value, then each humidity value is less than the standard humidity value. Therefore, it can be determined that the clothes are dried.
[0026] Compared with the prior art, the beneficial effects of the clothes care machine provided by the present invention are as follows: by forming a capacitor with the first electrode and the second electrode and taking the clothes as a part of the dielectric, the humidity of the clothes themselves can be directly detected, thereby improving the accuracy of the result of judging whether the clothes have been dried.

When there are multiple pieces of clothes, the humidity value of the clothes in the middle position of multiple pieces of clothes can also be detected. Based on each humidity value, it is judged whether the clothes are dried, thereby improving the accuracy of clothes drying judgment. Description of the Drawings

[0033] Some embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the protection scope of the present invention. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios.
[0034] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation of the present invention. In addition, ordinal numbers such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0035] It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0036] Based on the problem in the prior art pointed out in the background art that the result of judging whether the clothes are dried during the drying process of the clothes care machine is not accurate enough, the present invention provides a clothes care machine, aiming to directly detect the humidity of the clothes itself by forming a capacitor composed of a first electrode and a second electrode and taking the clothes as a part of the dielectric, thereby improving the accuracy of the result of judging whether the clothes are dried; the present invention also provides a control method for the clothes care machine, obtaining the corresponding humidity value through the capacitance between every two adjacent electrodes, which can detect the humidity value inside the clothes. When there are multiple pieces of clothes, it can also detect the humidity value of the clothes at the middle position among multiple pieces of clothes. Based on each humidity value, it is judged whether the clothes are dried, improving the accuracy of clothes drying judgment.
[0037] First, refer to Figure 1 , which shows the overall structure of the clothes care machine of the present invention. As Figure 1As shown in the figure, the clothing care machine includes a cabinet body 1 and a door body. The cabinet body 1 and the door body enclose a care cavity 2. Inside the care cavity 2, there are a first electrode 3 and a second electrode 4. The first electrode 3 and the second electrode 4 are arranged on the opposite side walls of the cabinet body 1. There are insulating parts between the first electrode 3 and the cabinet body 1 and between the second electrode 4 and the cabinet body 1, such as rubber pads, ceramic plates, etc. The clothing care machine also includes a clothes hanger 5 and a detection unit. The clothes hanger 5 is arranged between the first electrode 3 and the second electrode 4. There is a conductive structure on the clothes hanger 5. The conductive structure and the clothes hanging on the clothes hanger 5 form an induction electrode. The detection unit can detect the capacitance between any two electrodes so that the control unit can obtain the capacitance. The control unit can calculate the humidity value based on the capacitance, and then judge whether the clothes are dried according to the humidity value. The control unit includes a processor and a memory. The memory is suitable for storing multiple program codes. The program codes are suitable for being loaded and run by the processor to execute the control method of the clothing care machine. Among them, the capacitance can be measured at different known humidity levels to establish a relationship model or look-up table between the capacitance and the humidity. This model or look-up table maps the capacitance to the relative humidity value. When the detection unit obtains the current capacitance, the control unit will use the above model or look-up table to convert the capacitance into a humidity value. Of course, the above method is not restrictive. As long as the humidity value can be obtained based on the capacitance, the acquisition method can be adjusted. These adjustments do not deviate from the principle of the present invention and are all within the protection scope of the present invention.
[0038] Those skilled in the art can understand that although it is described above that the care cavity 2 is enclosed by the cabinet body 1 and the door body, the cabinet body here can include the inner liner of the care machine and the outer shell of the care machine, but this is not restrictive. The care cavity 2 can also be composed only of the inner liner, and the first electrode 3 and the second electrode 4 are arranged inside the care cavity 2. In addition, although it is described above that there are insulating parts between the first electrode 3 and the cabinet body 1 and between the second electrode 4 and the cabinet body 1, this is not restrictive either. It is also possible to choose to set an insulating part between one of the first electrode 3 and the second electrode 4 and the cabinet body 1. In addition to setting insulating parts, a cabinet body 1 made of insulating materials can also be directly used, or an insulating coating can be provided on the inner wall of the cabinet body 1, or other insulating structures can be set, as long as the insulating setting between the first electrode 3 and the cabinet body 1 and / or the insulating setting between the second electrode 4 and the cabinet body 1 can be realized. Furthermore, although it is described above that there is a conductive structure on the clothes hanger 5, there can also be no conductive structure on the clothes hanger 5. The clothes hanging on the clothes hanger 5 are used as part of the dielectric. The detection circuit detects the capacitance between the first electrode 3 and the second electrode 4. The control unit obtains the capacitance and calculates the humidity value between the first electrode 3 and the second electrode 4 based on the capacitance, and then judges whether the clothes have been dried. The above adjustments do not deviate from the principle of the present invention and all belong to the protection scope of the present invention.
[0039] Specifically, regarding the setting of the clothes hanger 5, the angle of the clothes hanger 5 can be selected to be not perpendicular to both the first electrode 3 and the second electrode 4. Preferably, the first electrode 3 and the second electrode 4 are arranged parallel to each other. The clothes hanger 5 is arranged parallel to the first electrode 3 and the second electrode 4, which can increase the area of the clothes to be detected, thereby improving the humidity detection effect and ultimately improving the accuracy of the drying determination result. However, this is not restrictive. The first electrode 3 and the second electrode 4 can also be arranged at an angle as long as they can be energized to generate capacitance. The clothes hanger 5 can also be arranged perpendicular to the first electrode 3 and / or the second electrode 4 as long as the clothes hung on the clothes hanger 5 can be used as a dielectric to detect capacitance so as to detect the humidity of the clothes.
[0040] In addition, regarding the structures of the first electrode 3 and the second electrode 4, the first electrode 3 is the first electrode plate made of electrode material, and the second electrode 4 is the second electrode plate made of electrode material. The first electrode plate and the second electrode plate are directly installed on the side wall of the cabinet body 1, or can also be installed on the cabinet body 1 through a mounting bracket; the conductive structure on the clothes hanger 5 is the conductive plate made of electrode material, and the conductive plate is installed at a position on the clothes hanger 5 where it is easy to contact the clothes, so as to form an induction electrode with the clothes. Among them, the electrode material can be materials such as copper, graphite, aluminum tungsten alloy, steel, brass, etc., as long as it has good electrical conductivity and chemical stability.
[0041] It should be noted that the clothes hanger 5 can be a rotatable structure or a fixed structure. The clothes hanger 5 can also be replaced with other structures, such as a hook, a magnetic attraction member, etc., as long as it can hang clothes. In addition, one clothes hanger 5 can be provided, or multiple clothes hangers 5 can be provided. In the case where multiple clothes hangers 5 are provided, the clothes hangers 5 are preferably arranged in a row along the direction from the first electrode 3 to the second electrode 4, so that the induction electrode can divide the area between the first electrode and the second electrode into multiple parts, obtain multiple capacitances, get multiple humidity values, and judge the drying condition of the clothes according to the multiple humidity values, which can more accurately perform the drying determination and improve the accuracy of the drying determination result.
[0042] As a possible implementation manner, a third electrode is provided on the door body, and a fourth electrode is provided on the inner wall of the cabinet body 1 on the opposite side of the door body. The detection unit can also detect the capacitance between the third electrode and the fourth electrode, and can detect the capacitance between the first electrode 3 and the second electrode 4 according to the usage requirements, or detect the capacitance between the third electrode and the fourth electrode to achieve a better humidity detection effect; since the capacitor formed by the first electrode 3 and the second electrode 4 and the capacitor formed by the third electrode and the fourth electrode are perpendicular to each other or at a certain angle, the two-direction capacitors cannot be used simultaneously to avoid interference and affect the accuracy of the detection result.
[0043] Possibly, the detection unit includes a power supply and a capacitance detection circuit. The power supply is used to supply power to the capacitance detection circuit. Each electrode is connected to the capacitance detection circuit, and the capacitance value between two electrodes is obtained by the charge and discharge method or the oscillation method. Since the dielectric constant of water is greater than that of air, the greater the humidity of the clothes to be detected, the greater the dielectric constant and the greater the capacitance. Specifically, the charge and discharge method obtains the capacitance value by measuring the voltage change during the charging or discharging process of the capacitor, and the oscillation method sets the capacitance detection circuit as an oscillation circuit with a known frequency and obtains the capacitance value by measuring the frequency change of the oscillation circuit.
[0044] Then refer to Figure 2 , which shows the main step flow of the control method of the clothes care machine of the present invention, specifically including the following steps:
[0045] S100: Obtain the capacitance between every two adjacent electrodes.
[0046] S101: Obtain the humidity value between every two adjacent electrodes according to the capacitance.
[0047] S102: Based on each humidity value, determine whether the clothes are dried completely.
[0048] By obtaining the corresponding humidity value through the capacitance between every two adjacent electrodes, the humidity value inside the clothes can be detected. When there are multiple pieces of clothes, the humidity value between multiple pieces of clothes can also be detected. Based on each humidity value, it is determined whether the clothes are dried completely, improving the accuracy of clothes drying judgment.
[0049] Specifically, when there is one piece of clothes to be detected, the induction electrode formed by the clothes hanger and the clothes hanging on it divides the area between the first electrode and the second electrode into two parts. The detection unit detects the capacitance between the first electrode and the induction electrode, and the capacitance between the second electrode and the induction electrode. The two capacitance values are respectively used to calculate the humidity values of the two parts. Since the clothes hanger is arranged inside the clothes when the clothes are hung on the hanger, the clothes can be divided into two parts to detect their humidity values respectively, avoiding the situation that the humidity inside the clothes is not easily detected and the drying judgment is inaccurate; when there are multiple pieces of clothes to be detected, there are also multiple induction electrodes. The induction electrodes divide the area between the first electrode and the second electrode into multiple parts. The detection unit detects the capacitance between the first electrode and the adjacent induction electrode, the capacitance between each adjacent two induction electrodes, and the capacitance between the second electrode and the adjacent induction electrode. Each capacitance value is respectively used to calculate the humidity values of each part, which not only helps to detect the humidity inside the clothes, but also helps to detect the humidity of the clothes located in the middle of multiple pieces of clothes, improving the accuracy of the drying judgment result.
[0050] It should be noted that in step 100, the method for obtaining the capacitance between every two adjacent electrodes can be that the detection unit directly detects the capacitance between every two adjacent electrodes and then the control unit obtains it, or the detection unit detects the capacitance between any two electrodes and then the control unit obtains it, and then calculates the capacitance between every two adjacent electrodes. Those skilled in the art can make adjustments according to needs.
[0051] Finally, refer to Figure 3 , which shows the detailed step flow of an implementation manner of the control method of the clothing care machine of the present invention, specifically including the following steps:
[0052] S200: Obtain the capacitance between every two adjacent electrodes.
[0053] S201: Obtain the humidity value between every two adjacent electrodes according to the capacitance.
[0054] S202: Compare the magnitudes of the humidity values to obtain the maximum humidity value.
[0055] S203: Determine whether the maximum humidity value is less than or equal to a preset standard humidity value. If the judgment result is yes, execute step S204; if the judgment result is no, execute step S205.
[0056] S204: Determine that the clothing has been dried completely.
[0057] S205: Determine that the clothing has not been dried completely.
[0058] By obtaining the corresponding humidity value through the capacitance between every two adjacent electrodes, selecting the maximum humidity value among the humidity values corresponding to multiple parts, and comparing it with the determination standard for drying the clothing, i.e., the preset standard humidity value, the determination of the dryness of the clothing can be realized. If the maximum humidity value is less than or equal to the standard humidity value, then all the humidity values are less than the standard humidity value. Therefore, it can be determined that the clothing has been dried completely.
[0059] It should be noted that the above implementation manner is only used to illustrate the principle of the present invention and is not intended to limit the protection scope of the present invention. Without deviating from the principle of the present invention, those skilled in the art can adjust the above implementation manner so that the present invention can be applied to more specific application scenarios.
[0060] So far, the technical solution of the present invention has been described in combination with the preferred implementation manners shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific implementation manners. Without deviating from the principle of the present invention, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will all fall within the protection scope of the present invention.
