Description
Technical Field
[0001] The present invention relates to the technical field of clothing processing, and in particular provides a clothing processing device. Background Art
[0002] With the development and progress of science and technology, more and more people are accustomed to drying clothes directly through washing machines or dryers.
[0003] When a washing machine or a clothes dryer dries clothes, the dryness of the clothes needs to be detected. Since the drying drum is usually rotating, in order to facilitate layout, the prior art usually installs the sensor on the front bracket away from the door seal of the clothes. However, when a large amount of clothes needs to be dried or the clothes are far apart, the sensor cannot come into close contact with the clothes, resulting in the inability to accurately detect the dryness of the clothes.
[0004] Accordingly, the art needs a new clothes processing device to solve the above problems. Summary of the invention
[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the clothing processing equipment in the prior art cannot accurately detect the dryness of the clothing.

[0014] In a specific embodiment of the above-mentioned clothes processing device, the end of the third conductor in contact with the first conductor is set to a wedge structure; and / or the end of the fourth conductor in contact with the second conductor is set to a wedge structure.

DETAILED DESCRIPTION

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] As pointed out in the background technology, due to the rotation of the drying drum, in order to reduce the difficulty of arrangement, the dryness sensor in the prior art is installed on the front bracket away from the door seal of the clothes, and cannot come into close contact with the clothes, resulting in the problem that the dryness degree of the clothes cannot be accurately detected. The present invention provides a clothing processing device, which aims to achieve close contact with the clothes and accurately detect the dryness degree of the clothes by arranging the dryness sensor in the drying drum.
[0036] The clothing processing device of the present invention may be a washing machine, a washer-dryer, a clothes dryer, a drying machine, or the like that can dry clothing, and no specific limitation is made herein.
[0037] See first Figure 1 and Figure 2 , Figure 1 The cross-sectional structure of the clothes processing device of the present invention is shown. Figure 2 Shows Figure 1The partial enlarged structure of part A. The clothing processing device includes a drying drum 1 and a dryness sensor 2. The drying drum 1 is provided with a rotating shaft. The output shaft of the motor is connected to the rotating shaft and drives the drying drum 1 to rotate by driving the rotating shaft. Clothes to be dried are placed in the drying drum 1, and the clothes are dried while the drying drum 1 rotates; the dryness sensor 2 is arranged in the drying drum 1, and the dryness sensor 2 is used to detect the dryness of the clothes. The dryness sensor 2 is directly arranged in the drying drum 1 and can contact the clothes at a close distance, so as to achieve more accurate detection of the dryness of the clothes, especially when a large amount of clothes needs to be dried or the distance between the clothes is far, it does not affect the detection result. The clothing processing device also includes a first conductor 3, a second conductor 4, a third conductor 5, and a fourth conductor 6. The first conductor 3 is installed on the outer wall of the drying drum 1, and the first conductor 3 is electrically connected to the dryness sensor 2; the second conductor 4 is installed on the outer wall of the drying drum 1, and the second conductor 4 is connected to the dryness sensor 2 for communication; the third conductor 5 is fixedly arranged and in contact with the first conductor 3, and the third conductor 5 is electrically connected to the power supply; the fourth conductor 6 is fixedly arranged and in contact with the second conductor 4, and the fourth conductor 6 is connected to the controller of the clothing processing device for communication; the third conductor 5 is arranged in contact with the first conductor 3 for introducing electric energy and providing it to the dryness sensor 2, and the fourth conductor 6 is arranged in contact with the second conductor 4 for transmitting the detection result of the dryness sensor 2 to the controller; since the first conductor 3 and the second conductor 4 rotate with the drying drum 1, the third conductor 5 and the fourth conductor 6 are fixedly arranged, which avoids the dryness sensor 2 being arranged in the drying drum 1 and rotating with the drying drum 1, resulting in the line being cut, thereby improving the safety of use, ensuring the normal operation of the dryness sensor 2, and thus achieving the purpose of accurately detecting the dryness of the clothes.
[0038] Continue reading Figure 1 and Figure 2 The dryness sensor 2 includes a sensing element 21 and a dryness chip 22 connected to the sensing element 21. The dryness chip 22 is electrically connected to the first conductor 3 and is in communication connection with the second conductor 4. The sensing element 21 is used to sense the moisture change information in the drying drum 1 and transmit it to the dryness chip 22. The dryness chip 22 is used to process the information sensed by the sensing element 21 and convert it into the dryness of the clothes. The sensing element 21 is installed on the outer wall of the lifting rib 7 in the drying drum 1, and the dryness chip 22 is arranged inside the lifting rib 7. Since the lifting rib 7 rotates with the drying drum 1 and the contact between the lifting rib 7 and the clothes is more frequent and close, the sensing element 21 is arranged on the lifting rib 7, which helps to improve the accuracy of the sensing element 21 in detecting the dryness of the clothes. In addition, the lifting rib 7 also provides protection for the dryness chip 22, achieving the purpose of waterproofing, dustproofing and bump-proofing.
[0039] Optionally, the sensing element 21 is a metal sheet, which can form an electrostatic field with the drying drum 1 and sense the change of the electrostatic field, thereby achieving the purpose of detecting the humidity in the drying drum 1; a socket is provided on the lifting rib 7, and the end of the metal sheet is bent and plugged and fixed with the socket, which is convenient for the disassembly, maintenance and replacement of the sensing element 21. It should be noted that the bending structure of the metal sheet can be provided with multiple, and the corresponding socket is also provided with a number corresponding to the bending structure, for achieving a more secure installation. In addition, in addition to being plugged and fixed on the outer wall of the lifting rib 7, the sensing element 21 can also be fixed on the outer wall of the lifting rib 7 by integral injection molding, or can be installed on the outer wall of the lifting rib 7 by bolt installation or bonding installation. Those skilled in the art can make adjustments as needed, and these adjustments do not deviate from the principles of the present invention and are within the scope of protection of the present invention. Accordingly, the lifting rib 7 can be an insulating material such as plastic, or a non-insulating material. If the lifting rib 7 is a non-insulating material, an insulating layer 8 needs to be provided between the metal sheet and the lifting rib 7 to ensure that the metal sheet can accurately sense the change of the electrostatic field between the drying drum 1.
[0040] It will be understood by those skilled in the art that although the above Figure 1 and Figure 2 It is described that the sensing element 21 is installed on the outer wall of the lifting rib 7 in the drying drum 1, and the dryness determination chip 22 is arranged inside the lifting rib 7, but this is not restrictive. Those skilled in the art can set a separate protective shell for the dryness determination chip 22 as needed, as long as it can play a protective role. Those skilled in the art can also install the sensing element 21 directly on the inner wall of the drying drum 1 as needed, and set an insulating plate between the sensing element 21 and the inner wall of the drying drum 1.
[0041] As a possible implementation, the dryness sensor 2 is a 3D perspective drying sensor, which can emit countless electric field lines to the wall of the drying drum 1, forming a bipolar 3D detection field, dynamically scanning the clothes, and the changes in the moisture content of the clothes will affect the changes in the electrostatic field distribution. The sensor can sense these changes, and thus determine the moisture content of the clothes, that is, the degree of drying, through an intelligent algorithm. In addition, the dryness sensor 2 can be a capacitive sensor or a resistive sensor, and can also be a humidity sensor. As long as it can detect the humidity in the drying drum 1, it is within the protection scope of the present invention.
[0042] Continue reading Figure 1 and Figure 2The clothing processing device also includes a dynamic sealing structure, and the first conductor 3, the second conductor 4, the third conductor 5, and the fourth conductor 6 are all arranged within the coverage range of the dynamic sealing structure to prevent water or water vapor in the drying drum 1 from contacting the first conductor 3, the second conductor 4, the third conductor 5, and the fourth conductor 6 to affect their normal use; optionally, the dynamic sealing structure includes a first dynamic sealing ring 12 and a second dynamic sealing ring 13, the first dynamic sealing ring 12 is an annular member connected to the outer side of the rear wall of the drying drum 1, and the first dynamic sealing ring 12 is slidably connected to the rear shell of the clothing processing device, and the second dynamic sealing ring 13 is an annular member connected to the outer side of the front wall of the drying drum 1, and the second dynamic sealing ring 13 is slidably connected to the front shell of the clothing processing device.

[0044] It will be appreciated by those skilled in the art that although the above Figure 2 and Figure 3 It is described that the third conductor 5 and the fourth conductor 6 are both carbon brush blocks or carbon brush rods, but this is not restrictive, and the third conductor 5 and the fourth conductor 6 can also be other conductive structures such as conductive wires or conductive brushes.

Correspondingly, the third conductor 5 and the fourth conductor 6 are annular conductors and are fixedly arranged. Specifically, the third conductor 5 and the fourth conductor 6 can be installed on the bottom shell of the clothing processing device through a mounting frame. These adjustments do not deviate from the principles of the present invention and therefore will fall within the scope of protection of the present invention.

An insulating layer 8 is provided between the first conductor 3 and the second conductor 4 and the drying drum 1, and the insulating layer 8 is used to achieve insulation between the first conductor 3 and the second conductor 4 and the drying drum 1, respectively, to ensure the stability and safety of electrical and signal transmission.
[0047] As a possible implementation mode, an annular groove is provided on the insulating layer 8, and the first conductor 3 and the second conductor 4 are arranged in the annular groove; the annular groove is used to provide a limit for the first conductor 3 and the second conductor 4 to facilitate installation and positioning, and the annular groove also provides a limit for the corresponding conductive unit to prevent the conductive unit from slipping out of the third conductor 5 or the fourth conductor 6 in contact with it, resulting in poor electrical connection or communication connection or interruption.
