Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a detection device, clothing processing equipment and detection method for clothing processing equipment. Background Technology

[0002] Washing machines are common household appliances. During use, they inevitably accumulate dirt, which can contaminate clothes, necessitating regular cleaning. Some technologies quantify the degree of dirt in the washing machine based on the cumulative running time since the last cleaning, applying different cleaning programs to different levels of dirt. However, because the dirt level inside the drum isn't directly measured, this estimation can be inaccurate, inevitably leading to over-cleaning or incomplete cleaning.

[0003] To address the aforementioned problem of inaccurate estimations, such as Figure 1 As shown, a light emitting end 11' and a light receiving end 12' are provided in the garment processing equipment. The plane 13' where the light emitting end 11' and the light receiving end 12' are located is tangent to the inner drum 10', forming a tangent line 14'. The light emitting end 11' and the light receiving end 12' are located on both sides of the tangent line 14'. The light transmittance is calculated based on the light received by the light receiving end 12', and the degree of dirtiness of the inner drum 10' is determined based on the light transmittance. Since the plane 13' where the light emitting end 11' and the light receiving end 12' are located is tangent to the inner drum 10', after the garment processing equipment has been running for a period of time, the inner drum 10' may deviate from the rotation center. This would cause the plane 13' where the light emitting end 11' and the light receiving end 12' are located to intersect with or move away from the inner drum 10', which would lead to errors in the calculation of light transmittance and thus make the judgment of the degree of dirtiness of the inner drum 10' inaccurate.

[0004] Therefore, there is an urgent need for a detection device, clothing processing equipment, and detection method for clothing processing equipment to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a detection device for garment processing equipment, which improves the accuracy of detection and the reliability of detection results.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The detection device for the garment processing equipment includes an inner drum. The detection device for the garment processing equipment includes:

[0008] The detection device for the garment processing equipment includes an inner drum. The detection device for the garment processing equipment includes:

[0009] A signal transmitter is used to transmit electromagnetic wave signals to the outer surface of the inner cylinder, wherein the incident angle α of the electromagnetic wave signal on the outer surface of the inner cylinder is an acute angle.

[0010] A signal receiver, the signal receiver being used to receive the electromagnetic wave signal reflected by the outer surface of the inner cylinder;

[0011] A signal processing unit is provided, wherein the signal transmitter and the signal receiver are respectively communicatively connected to the signal processing unit, and the signal processing unit is configured to determine the degree of dirt on the outer surface of the inner cylinder.

[0012] The detection device of this garment processing equipment uses the principle of electromagnetic wave signal reflection for detection. It is not affected by the inner drum deviating from the rotation center or dynamic changes. Even if there is a slight deviation or vibration of the inner drum during operation, the electromagnetic wave signal can still be effectively reflected, ensuring the stability and accuracy of the detection results.

[0013] Optionally, the electromagnetic wave signal includes at least one of microwave, infrared, visible light, and ultraviolet light.

[0014] By selecting different types of electromagnetic wave signals, optimization can be performed for different types of dirt and the equipment's operating environment. For example, microwaves are suitable for cases where the outer surface of the inner drum is heavily soiled, visible light is suitable for cases where the outer surface of the inner drum is lightly soiled, and infrared and ultraviolet rays are more effective at detecting fine stains on the outer surface of the inner drum. This not only improves the versatility and adaptability of the detection device, but also enhances the cleaning effect of the garment processing equipment and the user experience.

[0015] Optionally, the signal transmitter and the signal receiver are arranged along the axial direction of the inner cylinder; and / or, the signal transmitter and the signal receiver are arranged along the circumferential direction of the inner cylinder.

[0016] By arranging the signal transmitter and receiver along the axial or circumferential direction of the inner drum, the flexibility and adaptability of the detection device in the garment processing equipment are further improved.

[0017] Optionally, the detection device of the garment processing equipment further includes:

[0018] A first base and a first locking member, wherein the signal transmitter is rotatably connected to the first base, and the first locking member is configured to lock the signal transmitter onto the first base;

[0019] And / or, the detection device of the garment processing equipment further includes a second base and a second locking member, wherein the signal receiver is rotatably connected to the second base and the second locking member is configured to lock the signal receiver onto the second base.

[0020] The signal transmitter is rotatably connected to the first base and can be locked by the first locking device, allowing the user to easily adjust the transmission direction of the signal transmitter according to actual needs. The signal receiver is rotatably connected to the second base and can be locked to the second base by the second locking member, allowing for flexible adjustment of the electromagnetic wave signal reception direction. This flexible adjustment capability helps to improve the detection accuracy of the electromagnetic wave signal.

[0021] Another objective of this invention is to provide a garment processing device that can accurately and directly determine the degree of dirt on the outer surface of the inner drum, thereby improving the accuracy and reliability of the detection results and thus increasing cleaning efficiency.

[0022] To achieve this objective, the present invention adopts the following technical solution:

[0023] A garment processing device includes an inner drum and a detection device for the garment processing device, wherein the detection device is used to detect the degree of dirt on the outer surface of the inner drum.

[0024] The detection device of the garment processing equipment directly detects the degree of dirt on the outer surface of the inner drum, improving the reliability and accuracy of the detection results. Users can perform appropriate cleaning operations based on the detection results to avoid over-cleaning or under-cleaning, thereby improving cleaning efficiency.

[0025] Optionally, the garment processing device further includes an outer cylinder, the inner cylinder is rotatably disposed inside the outer cylinder, and the signal transmitter and the signal receiver are disposed on the inner wall of the outer cylinder;

[0026] Alternatively, the garment processing device may further include an outer cylinder made of transparent material, an inner cylinder rotatably disposed within the outer cylinder, and a signal transmitter and a signal receiver located on the side of the outer cylinder opposite to the inner cylinder.

[0027] The positions of the signal transmitter and receiver can be flexibly set according to different detection needs. The detection device of the garment processing equipment can detect the inner drum of the garment processing equipment alone, or the garment processing equipment can detect the inner drum and the outer drum at the same time. This ensures that all potentially dirty areas are detected, preventing over-cleaning or under-cleaning. In addition, users can also intuitively observe the cleanliness of the inner drum through the transparent outer drum, which helps to improve user satisfaction with the garment processing equipment.

[0028] Optionally, the garment processing device further includes an outer cylinder made of a non-transparent material, and a transparent component is provided on the outer cylinder. The inner cylinder is rotatably disposed inside the outer cylinder, and the signal transmitter and the signal receiver are located on the side of the transparent component away from the inner cylinder.

[0029] The electromagnetic wave signal emitted by the signal transmitter is refracted by the upper transparent part of the outer cylinder and then covered on the outer surface of the inner cylinder. After being reflected by the outer surface of the inner cylinder, the electromagnetic wave signal is refracted again by the upper transparent part of the outer cylinder and received by the signal receiver. Based on the signal strength of the received electromagnetic wave, the degree of dirtiness of the inner and outer cylinders can be detected simultaneously, and over-cleaning or under-cleaning can be avoided.

[0030] Another objective of this invention is to provide a detection method for clothing processing equipment that can accurately reflect the actual soiling status of the inner drum, thereby improving the accuracy and reliability of the detection.

[0031] To achieve this objective, the present invention adopts the following technical solution:

[0032] A testing method for garment processing equipment, applied to the aforementioned testing device for garment processing equipment, wherein the testing method for garment processing equipment includes:

[0033] The signal transmitter emits an electromagnetic wave signal to the outer surface of the inner cylinder, and the incident angle α of the electromagnetic wave signal on the outer surface of the inner cylinder is an acute angle.

[0034] The signal receiver receives the electromagnetic wave signal reflected by the inner cylinder;

[0035] The signal processing unit compares the intensity of the electromagnetic wave signal received by the signal receiver with the intensity of the electromagnetic wave signal emitted by the signal transmitter to determine the degree of dirtiness of the inner cylinder.

[0036] The detection method of this garment processing equipment is based on the principle of electromagnetic wave signal reflection to directly detect the degree of dirt on the outer surface of the inner drum. It does not rely on traditional cumulative running time estimation or light transmittance calculation, which can avoid misjudgment caused by inner drum displacement or position change, and can more directly and accurately judge the degree of dirt on the inner drum surface.

[0037] Optionally, if the ratio of the electromagnetic wave signal intensity received by the signal receiver to the electromagnetic wave signal intensity emitted by the signal transmitter is greater than 0.8 and less than or equal to 1, it is identified as slightly dirty.

[0038] When the ratio of the electromagnetic wave signal intensity received by the signal receiver to the electromagnetic wave signal intensity emitted by the signal transmitter is greater than 0.5 and less than or equal to 0.8, it is identified as moderately dirty.

[0039] When the ratio of the electromagnetic wave signal intensity received by the signal receiver to the electromagnetic wave signal intensity emitted by the signal transmitter is less than or equal to 0.5, it is identified as heavily soiled.

[0040] By dividing the range of electromagnetic wave signal intensity ratios, the degree of dirtiness of the inner drum can be accurately classified, allowing users to more accurately understand the dirtiness of the inner drum and perform corresponding cleaning operations based on the dirtiness level.

[0041] Optionally, at least two sets of detection devices of the clothing processing equipment are provided in the axial direction and / or circumferential direction of the inner cylinder, and the received electromagnetic wave signal intensity value is the average value of at least two sets of electromagnetic wave signal intensity values.

[0042] By averaging the intensity values ​​of at least two sets of electromagnetic wave signals, the overall dirt status of the inner cylinder can be reflected more accurately, reducing errors caused by local detection.

[0043] Beneficial effects:

[0044] The detection device for garment processing equipment provided by this invention includes a signal transmitter, a signal receiver, and a signal processing unit. The signal transmitter emits electromagnetic wave signals to the outer surface of the inner drum, with the incident angle α of the electromagnetic wave signal being an acute angle.

The signal transmitter and the signal receiver are respectively communicatively connected to the signal processing unit. The signal processing unit can determine the degree of dirt on the outer surface of the inner drum based on the ratio of the intensity of the received electromagnetic wave signal to the intensity of the emitted electromagnetic wave signal. This detection device for garment processing equipment utilizes the principle of electromagnetic wave signal reflection for detection, and is not affected by the inner drum deviating from the rotation center or dynamic changes. Even if the inner drum has slight deviations or vibrations during operation, the electromagnetic wave signals can still be effectively reflected, ensuring the stability and accuracy of the detection results.

[0045] The garment processing equipment provided by this invention can directly detect the degree of dirt on the outer surface of the inner drum, improving the reliability and accuracy of the detection results.

[0063] Example 1

[0064] This embodiment provides a detection device for a garment processing equipment, which includes an inner drum 10, such as... Figures 2-4As shown, the detection device of the garment processing equipment includes a signal transmitter 100, a signal receiver 200, and a signal processing unit. The signal transmitter 100 is used to emit electromagnetic wave signals to the outer surface of the inner drum 10. The incident angle α of the electromagnetic wave signal on the outer surface of the inner drum 10 is an acute angle. The signal receiver 200 is used to receive the electromagnetic wave signals reflected by the outer surface of the inner drum 10. The signal transmitter 100 and the signal receiver 200 are respectively connected to the signal processing unit. The signal processing unit can determine the degree of dirt on the outer surface of the inner drum 10 based on the ratio of the intensity of the received electromagnetic wave signal to the intensity of the emitted electromagnetic wave signal. The detection device of this garment processing equipment uses the principle of electromagnetic wave signal reflection for detection. It is not affected by the inner drum 10 deviating from the rotation center or dynamic changes. Even if the inner drum 10 has slight deviations or vibrations during operation, the electromagnetic wave signals can still be effectively reflected, ensuring the stability and accuracy of the detection results.

[0065] It should be noted that the detection principle in this embodiment is based on the fact that when the outer surface of the inner cylinder 10 is free of dirt, the signal transmitter 100 emits an electromagnetic wave signal to the inner cylinder 10 at a certain intensity. After reflection by the inner cylinder 10, the intensity of the electromagnetic wave signal received by the signal receiver 200 remains almost unchanged. However, as the degree of dirt on the outer surface of the inner cylinder 10 increases, some electromagnetic wave signals will be scattered, and the signal intensity received by the signal receiver 200 will weaken accordingly. By detecting the intensity of the electromagnetic wave signal received by the signal receiver 200, the degree of dirt on the outer surface of the inner cylinder 10 at this point can be determined. In conjunction with the rotation of the inner cylinder 10, the degree of dirt around the inner cylinder 10 can be detected.

[0066] In this embodiment, the incident angle α of the electromagnetic wave signal can be understood as the angle between the electromagnetic wave signal and the perpendicular line at the incident point to the curved surface (outer surface of the inner cylinder 10). This perpendicular line is called the surface normal. The specific location of the incident angle α is as follows: Figure 3 As shown.

[0067] In this embodiment, the signal processing unit can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to process the received electromagnetic wave signals, thereby determining the degree of dirt on the outer surface of the inner cylinder 10. It should be noted that the control program running in the microcontroller is a technique well-known to those skilled in the art and will not be described in detail here.

[0068] Optionally, such as Figure 2 and Figure 3As shown, this embodiment is illustrated by arranging the signal transmitter 100 and the signal receiver 200 along the axial direction of the inner cylinder. The incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 is greater than 0° and less than 90°. Specifically, the incident angle α can be 15°, 30°, 45°, 60°, or 75°. In this embodiment, it is preferred that the incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 is 45°.

[0069] In another embodiment, such as Figure 4 As shown, the signal transmitter 100 and the signal receiver 200 are arranged along the circumferential direction of the inner cylinder 10. The incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 is greater than 0° and less than 90°. Specifically, the incident angle α can be 15°, 30°, 45°, 60°, 75°, etc. In this embodiment, it is preferred that the incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the inner cylinder is 45°.

[0070] In another embodiment, a set of signal transmitters 100 and signal receivers 200 are arranged along the axial direction of the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 has an incident angle of 45° on the outer surface of the inner cylinder 10. At the same time, another set of signal transmitters 100 and signal receivers 200 are arranged along the circumferential direction of the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 has an incident angle of 45° on the outer surface of the inner cylinder 10. A set of detection devices is set in the axial direction and the circumferential direction of the inner cylinder 10, which improves the detection accuracy and ensures the accuracy and reliability of the detection results.

[0071] Optionally, the electromagnetic wave signal includes at least one of microwaves, infrared radiation, visible light, and ultraviolet radiation. By selecting different types of electromagnetic wave signals, optimization can be performed for different types of dirt and the equipment's operating environment. For example, microwaves are suitable for cases where the outer surface of the inner drum 10 is heavily soiled, visible light is suitable for cases where the outer surface of the inner drum 10 is lightly soiled, and infrared and ultraviolet radiation are more effective at detecting fine stains on the outer surface of the inner drum 10. This not only improves the versatility and adaptability of the detection device but also enhances the cleaning effect of the garment processing equipment and the user experience.

[0072] Specifically, microwave signals are typically emitted by a microwave generator or antenna. Commonly used microwave transmitting devices include magnetrons and solid-state microwave transmitters. The microwave transmitter used to detect the degree of dirt on the inner cylinder 10 generally emits at an intensity of approximately 0.1mW to 10mW, ensuring that the microwaves have sufficient penetrating power to penetrate the dirt on the outer surface of the inner cylinder 10 without causing damage. The electromagnetic wave signal intensity emitted by the microwave transmitter can be 0.1mW, 0.5mW, 1.0mW, 1.5mW, 2.0mW, 2.5mW, 3.0mW, 3.5mW, 4.0mW, 4.5mW, 5.0mW, 5.5mW, 6.0mW, 6.5mW, 7.0mW, 7.5mW, 8.0mW, 8.5mW, 9.0mW, 9.5mW, or 10.0mW. A microwave signal intensity of 5.0mW is preferred.

[0073] Infrared radiation is typically emitted by infrared emitting diodes or quantum cascade lasers. Common infrared emitters are LED infrared emitters, which emit narrowband or broadband infrared radiation; the infrared emission intensity of devices used for detection is generally around 0.1 mW / cm². 2 Up to 10mW / cm 2 Between. The infrared emission intensity can be 0.1 mW / cm. 2 0.5mW / cm 2 1.0mW / cm 2 1.5mW / cm 2 2.0mW / cm 2 2.5mW / cm 2 3.0mW / cm 2 3.5mW / cm 2 4.0mW / cm 2 4.5mW / cm 2 5.0mW / cm 2 5.5mW / cm 2 6.0mW / cm 2 6.5mW / cm 2 7.0mW / cm 2 7.5mW / cm 2 8.0mW / cm 2 8.5mW / cm 2 9.0mW / cm 2 9.5mW / cm 2 10.0mW / cm 2 Infrared wavelengths typically range from 700 nm to 1000 nm, specifically 700 nm, 800 nm, 900 nm, and 1000 nm, with appropriate wavelengths and intensities selected based on different detection requirements. The preferred infrared intensity is 5.0 mW / cm².2 The wavelength of infrared light is preferably 800nm.

[0074] Visible light is typically generated by LED lights, and its intensity is expressed as luminous flux (lumens, lm) or illuminance (lux, lx). The visible light emission intensity commonly used for detection is typically around 1 lm / cm². 2 Up to 10 lm / cm 2 Within the range, specifically 1 lm / cm 2 2lm / cm 2 3lm / cm 2 4lm / cm 2 5lm / cm 2 6lm / cm 2 7lm / cm 2 8lm / cm 2 9lm / cm 2 10lm / cm 2 Within this intensity range, visible light is sufficient to illuminate the outer surface of the inner cylinder and can be reflected by the outer surface of the inner cylinder to the signal receiver to detect the attenuation of the visible light. In this embodiment, the intensity of visible light is preferably 5 lm / cm². 2 .

[0075] Ultraviolet light is emitted by ultraviolet LEDs (UV LEDs) or mercury lamps. UV LEDs have become commonly used ultraviolet emitters, especially suitable for low-power detection devices, where the ultraviolet intensity is typically 0.01 mW / cm². 2 Up to 10mW / cm 2 Specifically, it can be 0.1mW / cm 2 0.5mW / cm 2 1.0mW / cm 2 1.5mW / cm 2 2.0mW / cm 2 2.5mW / cm 2 3.0mW / cm 2 3.5mW / cm 2 4.0mW / cm 2 4.5mW / cm 2 5.0mW / cm 2 5.5mW / cm 2 6.0mW / cm 2 6.5mW / cm 2 7.0mW / cm 2 7.5mW / cm 2 8.0mW / cm 2 8.5mW / cm 2 9.0mW / cm2 9.5mW / cm 2 10.0mW / cm 2 The wavelength is between 10nm and 400nm; the wavelength of ultraviolet light can be 10nm, 50nm, 100nm, 150nm, 200nm, 250nm, 300nm, 350nm, 400nm, 450nm, or 500nm. The preferred intensity of the ultraviolet light is 5.0mW / cm². 2 In this embodiment, the wavelength of the ultraviolet light is preferably 300nm. These electromagnetic wave emitting devices and intensity ranges can be selected and adjusted according to different detection requirements to adapt to different types of dirt detection scenarios.

[0076] Optionally, the outer surface of the inner cylinder 10 is smooth; or, the inner cylinder 10 has a smooth area in its circumferential direction, and the incident position of the electromagnetic wave signal is located on the smooth surface or smooth area. Incidence and reflection of electromagnetic wave signals on the smooth surface or smooth area of ​​the inner cylinder 10 provides a clear detection benchmark. When the surface of the inner cylinder 10 is clean, the intensity of the electromagnetic wave signal received by the signal receiver 200 remains almost unchanged after reflection from the inner cylinder 10. However, as the degree of dirt on the outer surface of the inner cylinder 10 increases, some electromagnetic wave signals will be scattered, and the signal intensity received by the signal receiver 200 will weaken accordingly. By detecting the intensity of the electromagnetic wave signal received by the signal receiver 200, the degree of dirt on the outer surface of the inner cylinder 10 at this location can be determined. Combined with the rotation of the inner cylinder 10, the degree of dirt around the circumference of the inner cylinder 10 can be detected. The reflected intensity of the electromagnetic wave signal is high, and the signal is stable. As dirt accumulates, these smooth areas become covered by dirt, causing a significant attenuation of the signal reflection intensity. This significant attenuation allows the detection system to clearly determine the degree of dirt on the inner cylinder 10, thereby improving the sensitivity and accuracy of the detection.

[0077] In one embodiment, the detection device of the garment processing equipment further includes a first base and a first locking member. The signal transmitter 100 is rotatably connected to the first base, and the first locking member is used to lock the signal transmitter 100 onto the first base. Specifically, the first base has a first through hole, and the first locking member includes a first bolt and a first nut. The signal transmitter 100 has a second through hole, and the first and second through holes are coaxially arranged. The first bolt passes through the first and second through holes in sequence and is threadedly connected to the first nut. After adjusting the incident angle of the signal transmitter 100, the first bolt and the first nut are locked. The arrangement of the first base and the first locking member facilitates adjusting the optimal incident position of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 according to the diameter of the inner cylinder 10, thereby improving the reflection effect of the electromagnetic wave signal and improving the accuracy and reliability of the detection results.

[0078] In another embodiment, the detection device of the garment processing equipment further includes a second base and a second locking member. The signal receiver 200 is rotatably connected to the second base, and the second locking member is used to lock the signal receiver 200 onto the second base. Specifically, the second base has a third through hole, the second locking member includes a second bolt and a second nut, and the signal transmitter 100 has a fourth through hole. The third and fourth through holes are coaxially arranged, and the second bolt passes through the third and fourth through holes in sequence and is threadedly connected to the second nut. After adjusting the receiving angle of the signal receiver 200, the first bolt and the first nut are locked together. The rotatable connection between the signal receiver 200 and the second base facilitates adjustment of the receiving direction of the signal receiver 200, thereby improving the detection accuracy and the reliability of the detection results.

[0079] In this embodiment, the signal transmitter 100 is rotatably connected to the first base and can be locked by the first locking device, allowing the user to conveniently adjust the transmission direction of the signal transmitter 100 according to actual needs; and the signal receiver 200 is rotatably connected to the second base and can be locked on the second base by the second locking member, allowing for flexible adjustment of the receiving direction of the electromagnetic wave signal. This flexible adjustment capability helps to improve detection accuracy.

[0080] Example 2

[0081] This embodiment provides a garment processing device, including an inner drum 10 and a detection device for the garment processing device. The detection device of the garment processing device directly detects the degree of dirt on the outer surface of the inner drum 10, which improves the reliability and accuracy of the detection results. Users can perform appropriate cleaning operations based on the detection results to avoid over-cleaning or under-cleaning, thereby improving cleaning efficiency.

[0082] For example, the clothing handling equipment can be a dryer, which includes a dryer housing, a dryer inner drum, and a detection device. The detection device is disposed inside the dryer housing, and the inner drum is rotatably disposed inside the dryer housing. The detection device can detect the degree of dirt on the outer surface of the dryer inner drum, so that the user can understand the dirt status of the inner drum and perform an appropriate cleaning procedure, which helps to maintain the dryer in its best working condition and improve the drying effect.

[0083] Example 3

[0084] This embodiment provides a clothing processing device, which is basically the same as the clothing processing device in Embodiment 2. The difference is that the clothing processing device in this embodiment is a washing machine. The washing machine includes an inner drum 10, an outer drum 20, and a detection device for the clothing processing device. The outer drum 20 is made of transparent or non-transparent material. A signal transmitter 100 and a signal receiver 200 are disposed on the inner wall of the outer drum 20. The signal receiver 200 and the signal transmitter 100 are arranged in the circumferential direction of the inner drum 10 or along the axial direction of the inner drum 10. The signal transmitter 100 emits visible light. The incident angle α of the visible light on the inner drum 10 is 45°. After being reflected by the outer surface of the inner drum 10, the light returns to the signal receiver 200. The signal processing unit determines the degree of dirtiness of the inner drum 10 based on the intensity of the received visible light. Furthermore, as the inner drum 10 rotates, it can perform a comprehensive inspection of the inner drum 10.

[0085] Optionally, the outer cylinder 20 can be made of any one of epoxy resin, polytetrafluoroethylene, or borosilicate glass.

[0086] Specifically, epoxy resin has high hardness, chemical resistance and excellent transparency, making it suitable for use in the outer cylinder 20 of garment processing equipment that requires high durability and structural strength.

[0087] Polytetrafluoroethylene (PTFE) is chemically resistant and transparent, making it suitable for garment processing equipment in high-temperature or harsh environments, ensuring that the outer cylinder 20 is not damaged under extreme conditions.

[0088] Borosilicate glass has excellent transparency, heat resistance and impact resistance, maintaining the durability and safety of garment processing equipment, and allowing users to intuitively observe the working status of the inner drum 10.

[0089] Example 4

[0090] like Figure 5As shown, this embodiment provides a clothing processing device. Taking a washing machine as an example, the difference from Embodiment 3 is that the washing machine includes a washing machine shell, an outer drum 20, an inner drum 10, and a detection device. The outer drum 20 is made of transparent material and is disposed inside the washing machine shell. The inner drum 10 is rotatably disposed inside the outer drum 20. The detection device is located on the side of the outer drum away from the inner drum 10, and the signal transmitter 100 and signal receiver 200 of the detection device are arranged along the axial direction of the inner drum 10 on the outer drum 20. On the side away from the inner cylinder 10, the signal transmitter 100 in the detection device emits visible light. The visible light emitted by the signal transmitter 100 can pass through the transparent outer cylinder 20 and illuminate the outer surface of the inner cylinder 10. The incident angle α of the visible light on the outer surface of the inner cylinder is 45°. After being reflected by the inner cylinder 10 and refracted by the outer cylinder 20, the visible light returns to the signal receiver 200. Based on the intensity of the received visible light, the degree of dirtiness of the inner cylinder 10 and the outer cylinder 20 is determined. Furthermore, as the inner cylinder 10 rotates, a comprehensive inspection of the inner cylinder 10 can be performed.

[0091] For example, the judgment process is as follows: when the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.8 and less than or equal to 1, it is identified as slightly dirty, and the user is advised to lightly clean the inner drum 10; when the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.5 and less than or equal to 0.8, it is identified as moderately dirty, and the user is advised to moderately clean the inner drum 10; when the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is less than or equal to 0.5, it is identified as heavily dirty, and the user is advised to deeply clean the inner drum 10.

[0092] The detection device of the garment processing equipment provided in this embodiment can simultaneously detect the inner drum 10 and the outer drum 20. This comprehensive detection can ensure that all potentially dirty areas are detected, preventing over-cleaning or under-cleaning. In addition, users can also intuitively observe the cleanliness of the inner drum 10 through the transparent outer drum 20, which helps to improve user satisfaction with the garment processing equipment.

[0093] Example 5

[0094] This embodiment provides a garment processing device, which is basically the same as that in Embodiment 4, except that, as shown in Embodiment 4... Figure 6As shown, the signal transmitter 100 and the signal receiver 200 are arranged along the circumferential direction of the inner cylinder 10 on the transparent outer cylinder 20. The electromagnetic wave signal emitted by the signal transmitter 100 is first refracted by the outer cylinder 20 and then irradiates the outer surface of the inner cylinder 10. The incident angle of the electromagnetic wave signal on the outer surface of the inner cylinder 10 is 75°. After being reflected by the outer surface of the inner cylinder 10, it is refracted by the transparent outer cylinder 20 and finally returns to be captured by the signal receiver 200. The signal processing unit determines the degree of dirtiness of the inner cylinder 10 and the outer cylinder 20 based on the ratio of the intensity of the received electromagnetic wave signal to the intensity of the emitted electromagnetic wave signal. The specific judgment process is described in the judgment method in Embodiment 2, and will not be repeated here.

[0095] Example 6

[0096] This embodiment provides a detection device for a garment processing equipment, which is basically the same as the garment processing equipment in Embodiment 4. The difference from Embodiment 4 is that the garment processing equipment in this embodiment also includes an outer cylinder 20. The outer cylinder 20 is made of an opaque material and has a transparent component 21. The inner cylinder 10 is rotatably disposed inside the outer cylinder 20. The signal transmitter 100 and the signal receiver 200 are located on the side of the transparent component 21 away from the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 is refracted by the upper transparent component 21 of the outer cylinder 20 and then covered on the outer surface of the inner cylinder 10. After being reflected by the outer surface of the inner cylinder 10, the electromagnetic wave signal is refracted by the upper transparent component 21 of the outer cylinder 20 and then received by the signal receiver 200. Based on the signal strength of the received electromagnetic wave, the degree of dirtiness of the inner cylinder 10 and the outer cylinder 20 can be detected simultaneously, and over-cleaning or under-cleaning can be avoided.

[0097] For example, such as Figure 7As shown, the signal transmitter 100 and the signal receiver 200 are arranged along the axial direction of the inner cylinder 10 on the side of the transparent component 21 away from the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 is first refracted by the transparent component 21 and then irradiates the outer surface of the inner cylinder 10. The incident angle of the electromagnetic wave signal on the outer surface of the inner cylinder 10 is 60°. After being reflected by the outer surface of the inner cylinder 10, it is refracted by the transparent component 21 and finally returns to be captured by the signal receiver 200. The signal processing unit determines the degree of dirtiness of the inner cylinder 10 and the outer cylinder 20 based on the ratio of the intensity of the received electromagnetic wave signal to the intensity of the emitted electromagnetic wave signal. For example, if the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.8 and less than or equal to 1, it is identified as slightly dirty, and the user is advised to lightly clean the inner drum 10; if the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.5 and less than or equal to 0.8, it is identified as moderately dirty, and the user is advised to moderately clean the inner drum 10; if the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is less than or equal to 0.5, it is identified as heavily dirty, and the user is advised to deep clean the inner drum 10.

[0098] Example 7

[0099] This embodiment provides a garment processing device, which is basically the same as that in Embodiment Six, except that, as shown in Embodiment Six... Figure 8 As shown, the signal transmitter 100 and the signal receiver 200 are arranged along the circumferential direction of the inner cylinder 10 on the side of the transparent component 21 facing away from the inner cylinder. The electromagnetic wave signal emitted by the signal transmitter 100 is first refracted by the transparent component 21 on the outer cylinder 20 and then irradiates the outer surface of the inner cylinder 10. The incident angle of the electromagnetic wave signal on the outer surface of the inner cylinder 10 is 75°. After being reflected by the outer surface of the inner cylinder 10, it is refracted by the transparent component 21 and finally returns to be captured by the signal receiver 200. The signal processing unit determines the degree of dirtiness of the inner cylinder 10 and the outer cylinder 20 based on the ratio of the intensity of the received electromagnetic wave signal to the intensity of the emitted electromagnetic wave signal. The specific judgment process is described in the judgment method above and will not be repeated here.

[0100] Optionally, the transparent component 21 is snapped onto the outer cylinder 20, and a sealing ring is provided at the connection between the transparent component 21 and the outer cylinder 20 to ensure a sealing effect at the connection between the outer cylinder 20 and the transparent component 21. Specifically, the transparent component 21 is provided with one of a slot or a buckle, and the outer cylinder 20 is provided with the other of a slot or a buckle, with the buckle snapping into the slot.

[0101] In other embodiments, the transparent component 21 is bonded to the outer cylinder 20, which can ensure the connection strength between the transparent component 21 and the outer cylinder 20, and further improve the sealing performance at the connection between the transparent component 21 and the outer cylinder 20.

[0102] Specifically, the transparent component 21 can be a plastic sheet, which has high impact resistance and toughness, is lightweight and has good light transmission, thus ensuring detection accuracy.

[0103] In one embodiment, the transparent component 21 can be a glass plate, which has excellent light transmittance and clarity, thereby further improving the accuracy of the detection and ensuring the reliability of the detection results.

[0104] Example 8

[0105] This embodiment provides a detection method for garment processing equipment, applicable to the detection device of garment processing equipment in any of the above embodiments, such as... Figure 9 As shown, the testing methods for garment processing equipment include:

[0106] The signal transmitter 100 transmits electromagnetic wave signals to the outer surface of the inner cylinder 10, and the incident angle α of the electromagnetic wave signal on the outer surface of the inner cylinder 10 is an acute angle.

[0107] The signal receiver 200 receives the electromagnetic wave signal reflected by the inner cylinder 10;

[0108] The signal processing unit compares the intensity of the electromagnetic wave signal received by the signal receiver 200 with the intensity of the electromagnetic wave signal emitted by the signal transmitter 100 to determine the degree of dirtiness of the inner cylinder 10.

[0109] The detection method of the clothing processing equipment provided in this embodiment directly detects the degree of dirt on the outer surface of the inner drum 10 based on the principle of electromagnetic wave signal reflection. It does not rely on traditional cumulative running time estimation or light transmittance calculation, which can avoid misjudgment problems caused by the displacement or position change of the inner drum 10, and can more directly and accurately judge the degree of dirt on the surface of the inner drum 10.

[0110] The incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 is greater than 0° and less than 90°. Specifically, the incident angle α can be 15°, 30°, 45°, 60°, or 75°. In this embodiment, it is preferred that the incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder 10 is 45°.

[0111] In other embodiments, the signal transmitter 100 and the signal receiver are arranged along the circumferential direction of the inner cylinder 10. The incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the outer surface of the inner cylinder is greater than 0° and less than 90°. Specifically, the incident angle α can be 15°, 30°, 45°, 60°, 75°, etc. In this embodiment, it is preferred that the incident angle α of the electromagnetic wave signal emitted by the signal transmitter 100 on the inner cylinder is 45°.

[0112] In another embodiment, a set of signal transmitters 100 and signal receivers 200 are arranged along the axial direction of the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 has an incident angle of 45° on the outer surface of the inner cylinder. At the same time, another set of signal transmitters 100 and signal receivers 200 are arranged along the circumferential direction of the inner cylinder 10. The electromagnetic wave signal emitted by the signal transmitter 100 has an incident angle α of 45° on the outer surface of the inner cylinder 10. A set of detection devices is set in the axial direction and the circumferential direction of the inner cylinder 10, which improves the detection accuracy and ensures the accuracy and reliability of the detection results.

[0113] Optionally, if the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.8 and less than or equal to 1, it is marked as slightly dirty, and the user is advised to lightly clean the inner drum 10.

[0114] When the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is greater than 0.5 and less than or equal to 0.8, it is identified as moderately dirty, and users are advised to perform moderate cleaning of the inner drum 10.

[0115] When the ratio of the received electromagnetic wave signal intensity to the emitted electromagnetic wave signal intensity is less than or equal to 0.5, it is identified as heavily soiled, and users are advised to perform a deep cleaning of the inner drum 10.

[0116] For example, taking the signal transmitter 100 emitting visible light as an example, the intensity of the visible light emitted by the signal transmitter 100 is 10 lm / cm. 2 Based on the intensity of the visible light emitted by the signal transmitter 100, the signal intensity of the visible light received by the signal receiver is divided into three intervals. For example, when the intensity of the visible light received by the signal receiver 200 is less than or equal to 10 lm / cm², the signal intensity is divided into three intervals. 2 And greater than 8 lm / cm 2 The time indicates that the inner drum 10 is slightly dirty, and a light cleaning procedure is recommended; when the intensity of visible light received by the signal receiver 200 is less than or equal to 8 lm / cm². 2 And greater than 5 lm / cm 2 The time indicates that the inner drum is severely dirty (level 10), and a moderate cleaning procedure is recommended. The intensity of visible light received by the signal receiver 200 is less than or equal to 5 lm / cm². 2 The time indicates that the inner drum is heavily soiled (level 10), and users are advised to perform a deep cleaning procedure.

[0117] Optionally, the inner drum 10 is provided with at least two sets of detection devices for the garment processing equipment along its axial direction and / or circumferential direction. The received electromagnetic wave signal intensity value is taken as the average of the intensity values ​​of at least two sets of electromagnetic wave signals. Multiple sets of detection devices can cover multiple areas of the inner drum 10, making the detection more comprehensive. Furthermore, by taking the average of the intensity values ​​of at least two sets of electromagnetic wave signals, the overall dirt status of the inner drum 10 can be more accurately reflected, reducing errors caused by local detection.

[0118] For example, taking the emission of visible light by the signal transmitter 100 as an example, three sets of detection devices are provided along the axial direction of the inner cylinder 10. In conjunction with the rotation of the inner cylinder 10, all three sets of detection devices can detect the degree of dirtiness around the inner cylinder 10. For instance, after the detection is completed, the signal intensity of the visible light received by the signal receiver 200 in the three sets of detection devices is 9 lm / cm². 2 8lm / cm 2 7lm / cm 2 Therefore, the final electromagnetic wave signal strength received by the signal receiver 200 is (9+8+7) / 3, which is 8 lm / cm. 2 The system displays a moderate level of dirt, prompting the user to perform a moderate cleaning, thus avoiding over-cleaning or insufficient cleaning and improving cleaning efficiency and effectiveness.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
