Technical Field
[0001] The utility model relates to the technical field of clothing processing equipment, in particular to a clothing processing equipment with a drying function. Background Art
[0002] When a clothes dryer or a washer-dryer with a drying function is running a drying program, it is usually determined whether the drying is complete based on the humidity of the clothes. Usually, a resistance sensor is used for detection. Specifically, the sensor measures the resistance of the surface of the clothes by contacting the clothes, and calculates the surface humidity of the clothes based on the resistance value of the surface of the clothes, thereby determining whether the drying is complete. When the surface of clothes (such as clothes made of materials such as down or fleece) is dry but the inside is wet, the dryness of the surface of the clothes will cause the humidity value to meet the drying judgment requirements, and the drying will be misjudged in advance, resulting in the termination of the drying program, causing the clothes to fail to be effectively dried, and the user experience is poor.
[0003] To this end, a solution has been proposed that uses a clothing treatment drum, the clothing therein and an electrode plate to form a humidity sensing unit, and detects the change in the dielectric constant of the dielectric of the humidity sensing unit to obtain the current humidity of the clothing.

[0057] Embodiment 1
[0058] This embodiment provides a clothes processing device with a drying function, which can more accurately determine the degree of drying completion of clothes 100, and can be applied to clothes 100 of different materials, especially clothes 100 of materials such as down and fleece, so as to improve the user experience. The clothes processing device with a drying function can be a dryer, a washer-dryer or other equipment with a drying function.
[0059] like Figure 1 As shown, the clothing processing device includes a casing, a clothing processing drum 11 rotatably disposed in the casing, and a door 12 movably connected to the casing, the clothing processing drum 11 is used to accommodate clothing 100, and an axial end of the clothing processing drum 11 is opened to form a take-in and put-out port, and the door 12 can open or close the take-in and put-out port. The clothing processing device also includes a driving assembly for driving the clothing processing drum 11 to rotate, and the driving assembly may include a motor, and the motor drives the clothing processing drum 11 to rotate to process the clothing 100. The processing procedures of the clothing processing device for clothing 100 include but are not limited to washing, spinning and drying the clothing 100. It should be pointed out that the clothing processing drum 11 is preferably grounded, so as to effectively protect the human body and avoid the risk of electric shock.
[0060] In order to judge the degree of dryness of the clothes 100, the clothes processing device also includes a humidity sensing component and a detection component 30. The humidity sensing component includes a first electrode plate 20 and a second electrode plate formed by a clothes processing drum 11. The clothes 100 in the clothes processing drum 11 can serve as a part of the dielectric of the humidity sensing component. The detection component 30 is electrically connected to the first electrode plate 20 and the second electrode plate, and is used to detect the change in the signal of the humidity sensing component, so as to judge the degree of dryness of the clothes 100 through the change.
[0061] The first electrode plate 20 and the second electrode plate are insulated and both are electrically connected to the detection component 30. The detection component 30 can detect the change in the signal of the humidity sensing component (the specific detection method is the existing technology, for example, the detection component 30 sends a fixed frequency signal to the first electrode plate 20, and transmits it to the second electrode plate through the clothing 100, and then the second electrode plate transmits the frequency signal to the detection component 30, and the detection component 30 can obtain the change in the signal of the humidity sensing component) and output it to the control unit 40. The humidity of the above-mentioned clothing 100 will decrease as the drying continues, so the dielectric constant of the dielectric of the humidity sensing component will change, which will also cause the change in the signal of the humidity sensing component to change (the specific principle can be referred to the capacitor).
[0062] Optionally, the clothing processing device further includes a control unit 40, and the control unit 40 is electrically connected to the detection component 30. The detection component 30 transmits the detected change in the signal of the humidity sensing component to the control unit 40, and the control unit 40 can obtain the current humidity value of the clothing 100 in real time according to the corresponding relationship between the humidity value of the clothing 100 obtained in the experiment and the change in the signal, and then determine whether the clothing 100 is completely dried according to the humidity value.
[0063] In this embodiment, the change amount of the above-mentioned signal can be a change value of voltage, that is, when the second electrode plate transmits the frequency signal to the detection component 30, the detection component 30 can convert it into a voltage value, and obtain the current voltage change value according to the voltage value. The change amount of the above-mentioned signal can also be a change value of frequency, that is, when the second electrode plate transmits the frequency signal to the detection component 30, the detection component 30 can obtain the frequency value, and then obtain the current frequency change value according to the frequency value. In this embodiment, the detection component 30 is powered by a DC power supply.
[0064] In order to improve the accuracy of judging the drying degree of the clothes 100, Figure 2 and Figure 3As shown, the first electrode plate 20 is disposed at the bottom end of the inner side surface of the machine door 12. Since the clothes processing drum 11 rotates when the clothes processing device processes the clothes 100, the clothes 100 adhere to the inner wall of the clothes processing drum 11 and rotate with the clothes processing drum 11, and the clothes 100 can more conveniently contact the bottom end of the inner side surface of the machine door 12, so as to increase the signal-to-noise ratio and improve the accuracy of the judgment of the drying degree of the clothes 100.
[0065] Furthermore, the first electrode plate 20 includes a main body, which is an arc-shaped plate 21 extending along the circumference of the clothing treatment drum 11. By providing the arc-shaped plate 21 extending along the circumference of the clothing treatment drum 11, the distance between the arc-shaped plate 21 and the clothing 100 attached to the inner wall of the clothing treatment drum 11 can be made closer, so that the first electrode plate 20 is convenient to contact with the clothing 100, thereby forming a capacitor through the clothing 100, the first electrode plate 20 and the second electrode plate. In addition, the special shape of the arc-shaped plate 21 can also ensure that the surface of the arc-shaped plate 21 can contact with the clothing 100 as much as possible, reduce the area of the arc-shaped plate 21 that is not in contact with the clothing 100, thereby increasing the signal-to-noise ratio, reducing interference signals, and thus improving the accuracy of judging the drying degree of the clothing 100.
[0066] In some embodiments, the main board body may also be a fan-shaped plate, with the center of the fan-shaped plate facing the center of the door, which may also increase the signal-to-noise ratio to a certain extent and reduce interference signals, thereby improving the accuracy of judging the drying degree of the clothes 100.
[0067] In some embodiments, the main board body may be a circular board to increase the signal-to-noise ratio, reduce interference signals, and improve the accuracy of determining the drying degree of the clothing 100 .
[0068] In this embodiment, the first electrode plate 20 can be fixed to the door 12 by bonding with an adhesive layer to avoid opening holes in the door 12 to affect the sealing performance.
[0069] Optionally, the first electrode plate 20 may be a metal plate or a conductive film layer made of a conductive material, wherein the conductive film layer may be made of silver paste to improve the conductivity. Alternatively, the first electrode plate 20 may include a metal plate and a conductive film layer disposed on the metal plate.
[0070] like Figure 3 As shown, the machine door 12 includes a door body 121 and an observation window 122. The door body 121 is provided with a mounting through hole, and the observation window 122 is arranged in the mounting through hole so that the user can observe the condition of the clothes 100 in the clothes processing drum 11 and the working status of the clothes processing drum 11 through the observation window 122.
[0071] In this embodiment, the arc plate 21 is arranged at the bottom end of the inner surface of the observation window 122, that is, the arc plate 21 is arranged close to the circumferential edge of the observation window 122 so that the arc plate 21 is in contact with the clothing 100 more to reduce interference signals.
[0072] In order to increase the effective area of the arc plate 21, the radial dimension of the arc plate 21 may be 1 / 4 to 1 / 3 of the radius of the laundry treatment tub 11, so as to reduce the area of the arc plate 21 that is not in contact with the laundry 100 on the basis of increasing the effective area of the arc plate 21, thereby increasing the signal-to-noise ratio, reducing interference signals, and thus improving the accuracy of the judgment of the drying degree of the laundry 100. Exemplarily, the radial dimension of the arc plate 21 may be 0.25, 0.26, 0.27, 0.28, 0.29, 0.3, 0.31, 0.32, or 0.33 of the radius of the laundry treatment tub 11.
[0073] like Figure 2 and Figure 3 As shown, the first electrode plate 20 also includes a connecting tail band 22a, one end of which is connected to the arc plate 21, and the other end serves as a detection end. The connecting tail band 22a is used to be electrically connected to the detection component 30 so that the detection component 30 can detect the change in the signal of the humidity sensing component.
[0074] Optionally, the connecting tail band 22 a extends in the radial direction of the arc-shaped plate 21 .
[0075] Optionally, the connecting tail band 22a is staggered with the symmetry axis of the arc plate 21, that is, the connecting tail band 22a is not connected to the lowest point of the arc plate 21. This arrangement can prevent the moisture in the laundry treatment drum 11 from condensing on the arc plate 21 and flowing along the lowest point of the arc plate 21 to the connecting tail band 22a, thereby affecting the test results.
[0076] Since the first electrode plate 20 is arranged inside the observation window 122 and is visible from the outside, the first electrode plate 20 is not only an electrical component for judging whether the clothes 100 are dried, but also an appearance component of the clothes processing device. In order to improve the appearance of the clothes processing device, the first electrode plate 20 also includes a decorative tail band 22b connected to the arc plate 21, and the decorative tail band 22b is used as an appearance component to beautify the appearance. Among them, the connecting tail band 22a and the decorative tail band 22b can be symmetrically arranged relative to the symmetry axis of the arc plate 21, that is, the connecting tail band 22a is located on one side of the symmetry axis, and the decorative tail band 22b is located on the other side of the symmetry axis, so that both are staggered with the lowest point of the arc plate 21 on the basis of improving the appearance.
[0077] It should be noted that the connecting tail band 22a connects the arc plate 21 and the detection drive plate 31, and the decorative tail band 22b is used as an appearance part, is not connected to the detection drive plate 31, and does not contact the clothing treatment drum 11 and the clothing therein.
[0078] In some embodiments, at least two decorative tail bands 22 b may be provided, so as to achieve the function of beautifying the appearance by orderly arranging the connecting tail band 22 a and the at least two decorative tail bands 22 b.
[0079] In order to reduce the interference of the connecting tail band 22 a on the detection signal, the length of the connecting tail band 22 a should be as short as possible, as long as the connection between the first electrode plate 20 and the detection component 30 can be achieved.
[0080] In order to conveniently shorten the length of the connecting tail band 22a, the detection component 30 includes a detection drive board 31 and a detection circuit 32. The detection drive board 31 is embedded in the machine door 12, and the detection drive board 31 is connected to the first electrode plate 20, and is used to detect the change in the signal of the humidity sensing component; the detection circuit 32 is used to connect the detection drive board 31, the first electrode plate 20 and the second electrode plate to form a detection circuit. By arranging the detection drive board 31 in the machine door 12, the first electrode plate 20 and the detection drive board 31 can be shortened, thereby shortening the length of the connecting tail band 22a, thereby reducing interference signals.
[0081] In this embodiment, the first electrode plate 20 is perpendicular to the rotation axis of the laundry treatment drum 11, so that the clothes 100 between the first electrode plate 20 and the laundry treatment drum 11 can be placed between the first electrode plate 20 and the second electrode plate of the humidity sensing component, and the change in the signal of the humidity sensing component can be detected. Of course, the first electrode plate 20 can also be installed on the door 12 in an acute angle with the rotation axis of the laundry treatment drum 11, as long as the change in the signal of the humidity sensing component can be obtained.
[0082] To facilitate powering the detection component 30, the clothing processing device also includes a power supply component 50 and a power supply line. The power supply component 50 is arranged in the casing, and the door 12 is rotatably connected to the casing through a hinge. One end of the power supply line is connected to the power supply component 50, and the other end passes through the hinge and extends into the door 12 to be connected to the detection drive board 31 to power the detection component 30.
[0083] In order to facilitate the fixing of the power supply line, a wiring groove is provided in the machine door 12, and the power supply line is arranged in the wiring groove, so that the extension direction of the power supply line is limited by the wiring groove, which is conducive to ensuring the stability of the line.
[0084] A fixing member may also be provided inside the machine door 12, and the fixing member is used to fix the power supply line, wherein the fixing member may be a wire tie or a wire clamp.
[0085] In some embodiments, only a wiring trough or only a fixing member may be provided to fix the power supply line.
[0086] In this embodiment, a protection element is provided on the detection circuit of the detection component 30, and the protection element has impedance to protect the detection drive board 31. The protection element can be a capacitor or a resistor, and it only needs to have a certain impedance performance to protect the detection drive board 31.
[0087] Exemplarily, the detection circuit 32 includes a first circuit section 321 connecting the detection driving board 31 and the laundry treatment drum 11, and the protection element is connected in series to the first circuit section 321. Figure 1 As shown, the protection element is a first protection capacitor 331 and a voltage regulator tube 332 connected in parallel, and the first protection capacitor 331 and the voltage regulator tube 332 connected in parallel are connected in series to the first line section 321. By setting the first protection capacitor 331 and the voltage regulator tube 332, the interference of the external power grid introduced by the grounding of the clothing treatment drum 11 can be effectively prevented, and the protection detection component 30 will not be damaged, and no logical confusion will occur. In addition, the static electricity generated during the drying process of the clothing 100 can be released, and the detection signal can be amplified, so that the detection result is more accurate.
[0088] The detection circuit 32 also includes a second circuit segment 322 located between the first electrode plate 20 and the detection driving plate 31. A protection element is also arranged on the second circuit segment 322, wherein the protection element can be a second protection capacitor 333 connected in series to the second circuit segment 322. The second protection capacitor 333 can filter the frequency signal sent by the detection component 30 to improve the detection effect, and can also prevent static electricity from impacting the detection component 30 and causing damage to the detection component 30.
[0089] When the clothes processing device in this embodiment detects the humidity of the clothes 100, the detection component 30 first detects the change in the signal of the humidity sensing component and outputs it to the control unit 40 of the clothes processing device. Then, the control unit 40 obtains the humidity value corresponding to the change in the signal of the current humidity sensing component according to the corresponding relationship between the change in the signal and the humidity of the clothes 100, and thus obtains the current humidity value of the clothes 100.
[0090] Furthermore, when the above-mentioned clothes processing device of this embodiment performs drying detection of clothes 100, the humidity value of clothes 100 is first obtained. The acquisition method can refer to the above-mentioned clothes 100 humidity detection method. After obtaining the current humidity value of clothes 100, the humidity value of clothes 100 is compared with the preset requirement for drying completion. If the humidity value of clothes 100 meets the preset requirement, it means that the clothes 100 are dried. The above-mentioned preset requirement can be a point value or a range value. As long as the humidity value of clothes 100 falls within the range, it can be judged that the clothes 100 are dried.
[0091] Embodiment 2
[0092] In this embodiment, based on the first embodiment, a humidity sensor is added to the clothing processing device. The humidity of the clothing 100 is detected simultaneously by the humidity sensor and the humidity sensing component, thereby achieving more accurate drying judgment and control.
[0093] For example, the humidity sensor of this embodiment can be arranged on the door 12, or on the front plate of the housing. The humidity sensor can be connected to the control unit 40, and the humidity sensor can contact the clothing 100, so that the control unit 40 can detect the resistance of the clothing 100, and judge the humidity value and drying condition of the surface of the clothing 100 according to the resistance of the clothing 100. That is to say, this embodiment detects the surface humidity of the clothing 100 through the humidity sensor, and detects the internal humidity of the clothing 100 through the humidity sensing component. According to the simultaneous detection of the surface and internal humidity of the clothing 100, it can accurately judge whether the clothing 100 is dried.
[0094] Of course, it is understandable that, depending on the type of clothing 100, you can choose to detect the surface humidity of clothing 100 only through the humidity sensor (such as clothing 100 is a thin shirt, etc.), or detect the humidity of clothing 100 only based on the humidity sensing component (such as clothing 100 made of down or brushed materials).
[0095] Optionally, the humidity sensor includes two metal bars embedded in the door 12 and insulated from each other, and the two metal bars can be electrically connected to the control unit 40, and the control unit 40 detects the resistance value of the clothes 100. Specifically, when the clothes 100 in the clothes treatment drum 11 are drying, the rotation of the clothes treatment drum 11 causes the clothes 100 to contact the two metal bars. Since the clothes 100 contain a certain amount of moisture, when the clothes 100 contact the metal bars, the control unit 40 can detect the resistance value of the clothes 100, and judge the humidity and drying status of the clothes 100 according to the size of the resistance value.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
