Description

[Technical Field]

[0001] This application claims priority from a Chinese patent application filed on March 10, 2023, bearing application number 202310228536.8, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of smart home appliances, such as a clothes treatment device, a clothes humidity detection method, and a clothes dryness detection method. [Background technology]

[0003] In a clothing processing process, particularly a drying process, whether drying is complete is generally determined based on the humidity of the clothing. In related technologies, this is generally done using an electrical resistance sensor. Specifically, the sensor contacts the clothing to measure the electrical resistance of the clothing surface, estimates the humidity value of the clothing surface from the electrical resistance value of the clothing surface, and determines whether the clothing is dry based on the humidity value. However, if the surface of clothing (e.g., clothing made of down, fleece, etc.) is dry but the inside is wet, the humidity value may meet the dryness determination criteria due to the dryness of the clothing surface, resulting in a premature erroneous determination of dryness, which ends the drying process and prevents the clothing from drying sufficiently, resulting in a poor user experience. Summary of the Invention [Problem to be solved by the invention]

[0004] The present application provides a clothing processing device, a clothing humidity detection method, and a clothing dryness detection method that can accurately determine the dryness of clothing and improve user experience. [Means for solving the problem]

[0006] One embodiment of the present application provides a clothing humidity detection method executed by the above-mentioned clothing processing device, which includes detecting a change in the signal of the inductive sensor unit when clothing is placed in the processing chamber, and obtaining a humidity value of the clothing based on a correspondence between the change in the signal and the humidity of the clothing, wherein the inductive sensor unit has a first electrode plate formed of at least one conductive plate and a second electrode plate formed in the processing chamber, and the clothing is part of the dielectric of the inductive sensor unit.

[0013] Example 1 To better determine whether clothes have been dried and to accommodate different materials, particularly down, fleece, and other materials, one embodiment of the present disclosure provides a clothing treatment device. As shown in FIGS. 1 and 11 , the clothing treatment device includes a housing 20 and a treatment chamber 1 rotatably mounted within the housing 20. The treatment chamber 1 accommodates clothes and is driven to rotate by a motor or other components to treat the clothes. The treatment processes performed by the treatment chamber 1 include, but are not limited to, washing, spin-drying, and drying. This disclosure focuses on a clothing treatment device with a drying process. In this embodiment, the treatment chamber 1 is preferably installed in a cylindrical structure and grounded, thereby effectively protecting the human body from the risk of electric shock.

[0014] In this embodiment, the clothing treatment device further includes an inductive sensor unit, a detection unit 3, and a control unit 4. The inductive sensor unit includes a first electrode plate formed of at least one conductive plate 2 and a second electrode plate formed in the treatment chamber 1, and the clothing in the treatment chamber 1 constitutes part of the dielectric of the inductive sensor unit. The first and second electrode plates are insulated from each other and electrically connected to the detection unit 3. The detection unit 3 detects the change in the signal from the inductive sensor unit (for a specific detection method, see the related art. For example, the detection unit 3 sends a signal of a certain frequency to the first electrode plate, which is then conducted through the clothing to the second electrode plate. The second electrode plate then transmits the frequency signal to the detection unit 3, allowing the detection unit 3 to obtain the change in the signal from the inductive sensor unit), and outputs the signal to the control unit 4. As the humidity of the clothing decreases as it dries, the dielectric constant of the dielectric of the inductive sensor unit changes, which in turn changes the change in the signal from the inductive sensor unit (for a specific principle, see the related art). Therefore, by detecting the signal change of the inductive sensor unit, the control unit 4 can obtain the current humidity value of the clothes in real time based on the experimental correspondence between the humidity value of the clothes and the signal change, and can further determine whether the clothes are completely dried from the humidity value. In this embodiment, the signal change may be a voltage change value. That is, after the second electrode plate transmits a frequency signal to the detection unit 3, the detection unit 3 converts the frequency signal to a voltage value, and the current voltage change value can be obtained from this voltage value. The signal change may also be a frequency change value. That is, after the second electrode plate transmits a frequency signal to the detection unit 3, the detection unit 3 obtains the frequency value, and then the current frequency change value can be obtained from the frequency value. In this embodiment, the detection unit 3 is powered by a DC power source.

[0015] In this embodiment, a protective element having impedance is provided in the detection circuit of the detection unit 3 to protect the detection unit 3. This protective element may be a capacitor or an electrical resistor, as long as it has a certain impedance performance and can protect the detection unit.

[0016] For example, the detection circuit includes a connection circuit 31 connected to the treatment chamber 1, and a protection element is connected in series to the connection circuit 31. In one embodiment, as shown in FIG. 1, the protection element is a first protection capacitor 5 and a voltage regulator diode 6 connected in parallel, which are connected in series to the connection circuit 31. The first protection capacitor 5 and the voltage regulator diode 6 effectively prevent interference with the external grid caused by the grounding of the treatment chamber 1, protecting the detection unit 3 from damage and preventing logical confusion. Furthermore, the detection signal can be amplified while discharging static electricity generated during drying of clothes, thereby improving the accuracy of the detection results.

[0017] In this embodiment, a second protective capacitor 7 is connected in series between the first electrode plate and the detection unit 3, and this second protective capacitor 7 can filter the frequency signal transmitted by the detection unit 3 to improve the detection effect and prevent static electricity from shocking and damaging the detection unit 3.

[0018] When detecting the humidity of clothes, the clothing processing device of this embodiment first detects the amount of change in the signal of the inductive sensor unit using the detection unit 3 and outputs the detected amount to the clothing processing device control unit 4. Then, the control unit 4 obtains the current humidity value of the clothes by acquiring the humidity value corresponding to the current amount of change in the signal of the inductive sensor unit based on the correspondence between the amount of change in the signal and the humidity of the clothes.

[0019] As shown in Figure 12, this embodiment provides a clothing humidity detection method, which includes detecting a change in the signal of the inductive sensor unit when clothing is placed in the treatment chamber 1, and obtaining a humidity value of the clothing based on the correspondence between the change in the signal and the humidity of the clothing, wherein the inductive sensor unit has a first electrode plate formed of at least one conductive plate 2 and a second electrode plate formed in the treatment chamber 1, and the clothing is part of the dielectric of the inductive sensor unit.

[0020] This embodiment further provides a clothes drying detection method, as shown in Figure 13, which includes detecting a change in the signal of the inductive sensor unit when clothes are placed in the processing chamber 1, obtaining a humidity value of the clothes based on the correspondence between the change in the signal and the humidity of the clothes, and determining that the drying of the clothes is complete based on whether the humidity value meets a predetermined requirement, wherein the inductive sensor unit has a first electrode plate formed of at least one conductive plate 2 and a second electrode plate formed in the processing chamber 11, and the clothes are part of the dielectric of the inductive sensor unit.

[0021] In this embodiment, when detecting whether clothes are dry, the clothing processing device first acquires the humidity value of the clothes. The acquisition means may refer to the clothing humidity detection method. After acquiring the current humidity value of the clothes, the humidity value is compared with the preset requirements for drying completion. If the humidity value of the clothes meets the preset requirements, it indicates that the clothes are dry. The preset requirements may be a single value or a range value. If the humidity value of the clothes is within this range, it can be determined that the clothes are dry.

[0022] The laundry processing device of this embodiment may be a dryer, a washer / dryer, or any other device having a drying function.

[0023] In the above-mentioned clothing treatment device of this embodiment, the detection unit 3 electrically connects the conductive plate 2 and the treatment chamber 1, thereby detecting the change in the signal of the inductive sensor unit and outputting it to the control unit 4 of the clothing treatment device. The control unit 4 then obtains the humidity value of the clothing based on the change in the signal of the inductive sensor unit, and can further determine the dryness status of the clothing from the humidity value, thereby enabling accurate humidity detection and dryness judgment, and improving the user experience.

[0024] Example 2 This embodiment is based on the first embodiment and will describe the configuration and mounting position of the conductive plate 2 that forms the first electrode plate. As shown in FIGS. 2 to 4, the conductive plate 2 of this embodiment is mounted on an insulating member 8, which is mounted inside the housing 20 of the clothing treatment device, specifically, on the inside of the front plate 9 of the housing 20 as shown in FIGS. 2 and 3, and is provided facing the treatment chamber 1. The conductive plate 2 is insulated from the treatment chamber 1 by the insulating member 8, making it possible to detect the amount of change in the signal of the formed inductive sensor unit. Furthermore, the clothing is placed between the first electrode plate and the second electrode plate, and serves as part of the dielectric.

[0025] In one embodiment, the insulating member 8 is an arc-shaped plate that can correspond to the shape and configuration of the front plate 9 of the housing 20. In addition, by providing a space in the front plate 9 where the insulating member 8 can be attached, it is possible to reduce the extra space occupied by attaching the insulating member 8. In other embodiments, the insulating member 8 may have another shape.

[0026] 3 and 4 , mounting holes 81 may be formed in the insulating member 8, and the insulating member 8 may be attached to the front plate 9 by passing screws through the mounting holes 81. Alternatively, locking holes 82 may be formed in the insulating member 8, and snaps may be provided corresponding to the front plate 9, and the snaps may be locked into the locking holes 82, thereby enabling the insulating member 8 to be quickly attached to and detached from the front plate 9.

[0027] 4, in this embodiment, the conductive plate 2 is provided on one side of the insulating member 8 away from the processing chamber 1 in order to achieve the purpose of being insulated from the processing chamber 1 via the insulating member 8. Alternatively, the conductive plate 2 may be parallel to the surface of the insulating member 8, which can better realize detection of the change in the signal of the formed inductive sensor unit.

[0028] In this embodiment, the conductive plate 2 is perpendicular to the rotation axis of the treatment chamber 1 so that the clothing between the conductive plate 2 and the treatment chamber 1 can be placed between the first and second electrode plates of the formed inductive sensor unit and so that the amount of change in the signal of the inductive sensor unit can be detected. Of course, the conductive plate 2 may be attached to the insulating member 8 so that it is parallel to the rotation axis of the treatment chamber 1 or at an angle to the rotation axis of the treatment chamber 1, as long as the amount of change in the signal of the inductive sensor unit can be obtained.

[0029] In this embodiment, a plurality of the conductive plates 2 may be provided, and the plurality of conductive plates 2 may be attached to insulating members 8 and insulated from each other. Alternatively, each conductive plate 2 may be attached to a single insulating member 8, and a plurality of insulating members 8 may be attached to the housing 20 of the clothing treatment device to form a plurality of inductive sensor units, thereby detecting the amount of change in the signals of the plurality of inductive sensor units, and further accurately measuring the humidity value of the clothing from the amount of change in the plurality of signals, thereby more accurately determining the dryness of the clothing.

[0030] Example 3 This embodiment is based on the second embodiment, but adds a humidity sensor 10 to the clothing treatment device, and the humidity sensor 10 and the inductive sensor unit simultaneously detect the humidity status of the clothing, thereby achieving more accurate dryness judgment and control.

[0031] 5 and 6, the humidity sensor 10 of this embodiment is integrally attached to the insulating member 8 and is provided on the side of the insulating member 8 facing the treatment chamber 1. The humidity sensor 10 is connected to the control unit 4 and can come into contact with the clothes so that the control unit 4 can detect the electrical resistance of the clothes and determine the humidity value and dryness state of the clothes from the electrical resistance of the clothes. That is, in this embodiment, the humidity sensor 10 detects the humidity on the clothes' surface, and the inductive sensor unit detects the humidity inside the clothes, and by simultaneously detecting the humidity on the clothes' surface and inside, it is possible to accurately determine whether the clothes have been dried.

[0032] Of course, depending on the type of clothing, it is possible to select whether to detect the surface humidity of the clothing using only the humidity sensor 10 (for example, thin clothing) or to detect the humidity of the clothing using only the inductive sensor unit (for example, clothing made of down or brushing material).

[0033] In this embodiment, the humidity sensor 10 and the conductive plate 2 are installed on both the left and right sides of the insulating member 8 with a gap between them, and the humidity sensor 10 and the conductive plate 2 are insulated by the insulating member 8. This prevents signal interference between them from affecting detection accuracy.

[0034] 5, the humidity sensor 10 includes two metal strips 101 that are fitted into the insulating member 8 and are spaced apart and insulated from each other. The two metal strips 101 can be electrically connected to the control unit 4, and the electrical resistance of the clothes is detected by the control unit 4. In one embodiment, when clothes are being dried in the treatment chamber 1, the clothes come into contact with the two metal strips 101 as the treatment chamber 1 rotates. Since the clothes contain a certain amount of moisture, when the clothes come into contact with the metal strips 101, the control unit 4 detects the resistance of the clothes and can determine the humidity and dryness of the clothes from the magnitude of the resistance.

[0035] In one embodiment, referring to FIG. 7 , two grooves 83 are formed at an interval in the insulating member 8, and two metal strips 101 are respectively fitted into the two grooves 83, and it is preferable that the depth of the grooves 83 is equal to or greater than the thickness of the metal strips 101, so that when the metal strips 101 are fitted into the grooves 83, the metal strips 101 do not protrude from the surface of the insulating member 8 and are prevented from getting caught on clothing in the treatment chamber 1.

[0036] Example 4 8 and 9, the clothing treatment device according to this embodiment differs from the clothing treatment device according to Example 3 only in that the humidity sensor 10 and conductive plate 2 according to this embodiment are installed on both the front and rear sides of the insulating member 8. In one embodiment, the conductive plate 2 and humidity sensor 10 are installed in order along the thickness direction of the insulating member 8, and are insulated from each other by the insulating member 8, with the humidity sensor 10 being closer to the treatment chamber 1 than the conductive plate 2 and able to come into contact with the clothing. By installing the humidity sensor 10 and conductive plate 2 on the front and back, the space occupied can be reduced.

[0037] The clothing processing device of this embodiment has the same configuration as that of the third embodiment except for the above, and therefore the description thereof will be omitted.

[0038] Example 5 The clothing treatment device of this embodiment differs from the clothing treatment device of Example 3 in that, as shown in Figure 10, one of the metal strips 101 in the humidity sensor 10 in this embodiment is a conductive plate 2, i.e., the humidity sensor 10 and the inductive sensor unit share one metal strip 101.

[0039] In this embodiment, the two metal strips 101 are installed with insulation between them, and when the clothes come into contact with the two metal strips 101, the control unit 4 detects the electrical resistance of the clothes (at this time, the inductive sensor unit does not function) to detect the humidity of the clothes surface. When the clothes are not in contact with the two metal strips 101, the metal strips 101 function as the conductive plate 2, and the humidity sensor 10 does not function. The detection unit 3 detects the change in the signal of the inductive sensor unit and outputs it to the control unit 4 of the clothing processing device. The control unit 4 can then obtain the humidity of the clothes based on the change in the signal of the inductive sensor unit, and can further determine the dryness of the clothes from the humidity value.

[0040] As shown in FIG. 10, in this embodiment, a plate-like structure 1011 may be integrally formed on the metal strip 101 as the conductive plate 2 to improve the detection accuracy when the conductive plate 2 is used as the first electrode plate of the induction sensor unit.

[0041] The other configuration of this embodiment is the same as that of the third embodiment, and therefore a description thereof will be omitted. [Explanation of symbols]
