[0042] A TOF module 20, which is installed on the door protection cover 11 for obtaining the internal environment conditions of the inner cylinder 30 of the clothing care device 1; wherein, the door protection cover 11 has an optical window for the TOF module 20. In some embodiments, the door protection cover 11 itself serves as the optical window of the TOF module 20; in some other embodiments, an independent sealing structure or window is provided on the door protection cover 11 to serve as the optical window.

[0043] In this embodiment, by providing the TOF module 20 to detect the internal environment conditions of the inner cylinder 30 of the clothing care device 1, it is convenient to execute corresponding washing programs and / or drying programs according to requirements, and optimize the clothing care effect; by using the door protection cover 11 as the protection structure and optical window of the TOF module 20, it effectively avoids the TOF module 20 from directly contacting the washing water, effectively guarantees the performance and application range of the TOF module 20, ensures the effectiveness and accuracy of the detection results of the TOF module 20, is convenient for maintenance and has low maintenance costs, and only needs to maintain the cleanliness of the door protection cover 11.

[0044] In some embodiments, the TOF module 20 can be configured as a TOF sensor; in still other embodiments, the TOF module 20 can also be configured as a TOF camera.

[0045] In one embodiment, at least one end of the TOF module 20 is located inside the door protective cover 11.

[0046] In some embodiments, the TOF module 20 can be set to extend only partially into the door protective cover 11. For example, when installing the TOF module 20, the transmitter 22 and the receiver 23 of the TOF module 20 are arranged inside the door protective cover 11.

[0047] In some preferred embodiments, the TOF module 20 is located inside the door protective cover 11. Specifically, the door 10 is hinged to the housing 40 of the clothing care device 1 to open and close the clothing inlet 31; the door protective cover 11 extends axially along the inner cylinder 30 into the inner cylinder 30, and a closed cavity 111 is recessed inside the door protective cover 11, and the TOF module 20 is installed in the cavity 111. By installing the TOF module 20 inside the door protective cover 11, the internal space of the door protective cover 11 is fully utilized, and the structure of the inner cylinder 30 does not need to be modified, optimizing the installation structure of the TOF module 20;

[0048] In some embodiments, the TOF module 20 includes a substrate 21, and a transmitter 22 and a receiver 23 arranged on the substrate 21; wherein, the substrate 21 is used to be fixed to the door protective cover 11, and a cover structure is formed on the surfaces of the transmitter 22 and the receiver 23.

[0049] Further, when the substrate 21 is fixed to the door protective cover 11, the transmitter 22 and the receiver 23 face the inside of the inner cylinder 30 of the clothing care device 1, and the door protective cover 11 forms the cover structure of the transmitter 22 and the receiver 23.

[0050] By forming an external encapsulation structure for the transmitter 22 and the receiver 23 with the help of the door protective cover 11, the original end cap component of the TOF module 20 is omitted, avoiding an increase in the light energy loss of the TOF module 20 caused by an increase in the thickness of the transmission surface, and effectively ensuring the performance and application range of the TOF module 20.

[0051] In some preferred embodiments, in combination Figure 3 and Figure 6 as shown, a groove 112 is formed on the inner surface of the door protective cover 11; when the substrate 21 is fixed to the door protective cover 11, the transmitter 22 and the receiver 23 are located in the groove 112, and the groove 112 forms as Figure 3The diffusion surfaces of the emitted light and the received light. Specifically, the groove 112 is recessed from the inner surface of the door protective cover 11 towards the inner environment of the inner cylinder 30. After the TOF module 20 is installed, the groove 112 surrounds the outside of the emitter 22 and the receiver 23 to form the light diffusion surfaces of the emitter 22 and the receiver 23. At the same time, the setting of the groove 112 can further reduce the thickness of the transmission surface of the TOF module 20, reduce light energy loss, and improve detection accuracy.

[0052] In some embodiments, the TOF module 20 is installed at the front end of the door protective cover 11.

[0053] In some preferred embodiments, a vertical plane 114 is formed at the front end of the door protective cover 11, and the groove 112 is provided on the vertical plane 114. Through the setting in this embodiment, it is convenient for the installation of the TOF module 20 and is conducive to accurately adjusting the light emission direction of the TOF module 20; and the vertical plane 114 is not easy to form water accumulation or water hanging, reducing the influence on the emitted light and the received light.

[0054] Furthermore, the contour of the door protective cover 11 gradually shrinks towards the inside of the cylinder along the axis direction of the inner cylinder 30 to form a water flow guiding structure; the door protective cover 11 can be cleaned by using water flow scouring to ensure the detection accuracy of the TOF module 20.

[0055] In some preferred embodiments, the bottom surface of the groove 112 has a planar structure.

[0056] Furthermore, as Figure 3 shown, the distance H between the end face of the emitter 22, the end face of the receiver 23 and the bottom surface of the groove 112 is 0 - 1.5 mm. Preferably, H is 1 mm.

[0057] Furthermore, as Figure 3 shown, the wall thickness T of the groove 112 is less than or equal to 1.5 mm.

[0058] In some embodiments, as Figure 2 shown, the angle α between the light emission direction of the emitter 22 and the axis direction of the inner cylinder 30 is 0 - 90°; in some preferred embodiments, the angle α between the light emission direction of the emitter 22 and the axis direction of the inner cylinder 30 is 0 - 75°. Specifically, in some embodiments, as Figure 3 shown, the light emission direction of the TOF module 20 can be parallel to the axis direction of the inner cylinder 30; in some other embodiments, as Figure 2As shown, the outgoing light direction of the TOF module 20 can also form a certain angle with the axis direction of the inner cylinder 30 to meet the detection requirements of different positions of the inner cylinder 30. In some preferred embodiments, by setting multiple TOF modules 20, the outgoing light directions of the respective TOF modules 20 are correspondingly adjusted to expand the application range and detection accuracy.

[0059] In some alternative embodiments, the substrate 21 is snap-fitted with the door protective cover 11, and this assembly method is simple and fast.

[0060] To further ensure the stability of the installation structure and prevent the TOF module 20 from falling or shifting due to the vibration of the clothing care device 1 during operation, in some alternative embodiments, the substrate 21 and the door protective cover 11 are fixedly assembled by fasteners such as screws or bolts.

[0061] In some preferred embodiments, in combination Figure 3 and Figure 6 As shown, an installation post 113 is further formed inside the door protective cover 11 for assembling with the substrate 21; specifically, the installation post 113 protrudes and extends away from the inner cylinder 30 from the inner surface of the door protective cover 11, and an installation hole 1131 is formed inside the installation post 113. A fitting hole 211 is formed at the corresponding position of the substrate 21. A fastener passes through the fitting hole 211 and is fixed to the installation hole 1131 to assemble the substrate 21 to the door protective cover 11; in this embodiment, by providing the installation post 113, it is convenient to assemble the TOF module 20 while being able to control a certain distance to be formed between the end face of the emitter 22, the end face of the receiver 23 and the bottom surface of the groove 112.

[0062] Furthermore, two installation posts 113 are provided, and the two installation posts 113 are respectively arranged at both ends of the groove 112.

[0063] In some embodiments, the door protective cover 11 is a transparent member, and the transparent member can be a glass material or a plastic material.

[0064] In some preferred embodiments, the door protective cover 11 is a transparent glass. The transparent glass has a high light transmittance and high wear resistance, which means that more light can pass through the door protective cover 11, thereby improving the light energy utilization rate and application range of the TOF module 20; and the glass material is relatively stable and is not easily affected by changes in temperature and humidity, which helps to maintain the performance of the TOF module 20 under different environmental conditions.

[0065] In still other embodiments, the door protective cover 11 has at least one transparent area that enables the TOF module 20 to perform optical irradiation. The set area of the transparent area is adapted to the layout of the TOF module 20, ensuring the application range of the emitted light and received light of the TOF module 20 while reducing the interference of external factors on the TOF module 20.
