[0059] Figures 1 to 10 The present invention provides an observation window for a garment processing device, comprising: an inner frame 10, a transparent window 20, a middle frame 30, and an outer frame 40.

[0060] An mounting opening 11 is formed in the middle of the inner frame 10, and an inner frame snap-fit ​​structure 100 is provided on the inner side of the inner frame 10. The edge 21 of the transparent window 20 fits into the inner side of the inner frame 10, and an inward protrusion structure 22 is formed in the middle of the transparent window 20, protruding outward from the inner frame 10 through the mounting opening 11. The middle frame 30 is fixedly connected to the inner side of the inner frame 10, and the middle frame 30 surrounds the mounting opening 11 and presses against the edge 21 of the transparent window 20 to fix the position of the transparent window 20. The inner side of the outer frame 40 fits into the inner side of the inner frame 10, and the outer frame 40 is provided with an outer frame snap-fit ​​structure 400, which snaps into the inner frame snap-fit ​​structure 100, thereby fixing the inner frame 10 and the outer frame 40 together. Furthermore, the outer frame snap-fit ​​structure 400 and the inner frame snap-fit ​​structure 100 can snap into each other at the same time as the outer frame 40 and the inner frame 10, making the installation simple and convenient.

[0061] When the observation window is installed on the equipment, the user can observe the internal state of the equipment through a single-layer transparent window 20. Compared with the double-layer structure observation windows of washing machines or dryers in the prior art, the observation window provided by this utility model omits the external transparent window screen, simplifies the installation steps, and greatly saves product costs, thereby enhancing the product's competitiveness. It also avoids the transparent window screen affecting clarity; the single-layer transparent window 20 provides higher clarity, facilitates user observation, and improves the user experience. The transparent window 20 is fixed by the middle frame 30, ensuring the installation stability of the transparent window 20. The middle frame 30 can be made of high-strength hard plastic, alloy materials, or other materials to ensure quality of use, while the transparent window 20 can be made of glass, plastic, or other transparent materials.

[0062] During installation, the transparent window 20 is installed in the mounting opening 11 of the inner frame 10, then the middle frame 30 is installed inside the inner frame 10, and finally the outer frame 40 is directly fastened to the inner frame 10. The outer frame fastening structure 400 and the inner frame fastening structure 100 can be directly engaged. The installation method of the outer frame 40 is simple and convenient, and no fasteners are required. Therefore, there is no need to drill holes in the outer frame 40 to install fasteners, which helps to maintain the integrity of the appearance of the outer frame 40. When installed on the equipment, the inner frame 10 faces the inside of the equipment, the inner convex structure 22 of the transparent window 20 extends into the inside of the equipment, and the outer frame 40 is located on the outside of the equipment. The outer frame 40 has a complete appearance, which can improve the user experience.

[0063] Specifically, the inner frame 10 and the middle frame 30 can be fixedly connected by fasteners. Multiple connecting posts 15 can be provided on the inner side of the inner frame 10, each with a threaded hole in the center. These connecting posts 15 are located near the mounting opening 11 and surround the edge 21 of the transparent window 20. The middle frame 30 has multiple connecting holes 32, each corresponding to a connecting post 15. Screws can be used as fasteners, passing through the connecting holes 32 and threadedly connected to the corresponding connecting post 15, thereby fixing the middle frame 30 and the inner frame 10 together. Installing the fasteners on the inner side of the inner frame 10 avoids opening holes on the outer side, reducing assembly gaps and minimizing leakage. After installing the outer frame 40, the fasteners can be hidden, reducing the risk of fasteners falling off.

[0064] The mounting opening 11 of the inner frame 10 and the edge 21 of the transparent window 20 need to be sealed together to prevent water leakage. A sealing element 50 can be installed between the edge of the mounting opening 11 and the edge 21 of the transparent window 20 for sealing. Specifically, the sealing element 50 is a sealing ring. The middle frame 30 can press the transparent window 20 tightly against the sealing element 50 to ensure the sealing effect.

[0065] The seal 50 surrounds the edge of the mounting port 11. The outer edge of the seal 50 extends to the outer side of the inner frame 10, forming a bent skirt structure. The inner edge of the seal 50 extends to the inner side of the inner frame 10. A groove for fixing the seal 50 can be provided on the inner side of the inner frame 10, and the inner edge of the seal 50 is inserted into the groove. The middle frame 30 can also press down on the seal 50 to further fix the seal 50.

[0066] To enhance structural strength, reinforcing ribs can be installed on the inner side of the inner frame 10 and the inner side of the outer frame 40, making the inner frame 10 and outer frame 40 less prone to deformation and improving their usability. The structural ribs of the inner frame 10 and the outer frame 40 can support each other or interlock. Furthermore, the inner frame interlocking structure 100 is a protrusion on the inner side of the inner frame 10, and the outer frame interlocking structure 400 is a protrusion on the inner side of the outer frame 40, allowing them to interlock.

[0067] In some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the observation window also includes a hinge assembly 60, which includes a pivot 61 and a mounting base 62. The mounting base 62 is provided with a connecting arm 621. Specifically, the mounting base 62 also includes a seat body 622, which is used for fixed connection to the device, and the connecting arm 621 is fixedly connected to the seat body 622.

[0068] The middle frame 30 is provided with a hinge mounting part 31, and the outer peripheral edge of the inner frame 10 is provided with a notch 12, which corresponds to the position of the hinge mounting part 31. The pivot 61 is provided on the hinge mounting part 31, and the fixing seat 62 extends into the notch 12 of the inner frame 10 through the connecting arm 621 and is rotatably connected to the pivot 61, rotating around the axis of the pivot 61.

[0069] The hinge assembly 60 is installed on the middle frame 30. The external force borne by the hinge assembly 60 acts on the middle frame 30, which can reduce the stress on the inner frame 10 and the outer frame 40, reduce the deformation and damage of the inner frame 10 and the outer frame 40, and make the outer frame 40 less likely to loosen or fall off.

[0070] In some embodiments of this utility model, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the inner frame snap-fit ​​structure 100 includes multiple inner frame snaps, some of which surround the outer periphery of the middle frame 30, some of which are arranged on the outer periphery of the inner frame 10, and some of which are arranged between the outer periphery of the inner frame 10 and the outer periphery of the middle frame 30. In other words, the inner frame snap-fit ​​structure 100 includes two rings of inner and outer frame snaps, and also includes several inner frame snaps located between the two rings of inner frame snaps. The outer frame snap-fit ​​structure 400 includes multiple outer frame snaps, with each outer frame snap corresponding to one of the inner frame snaps. When the outer frame 40 and the inner frame 10 are snapped together, the corresponding inner frame snaps and outer frame snaps engage with each other.

[0071] In some embodiments of this utility model, such as Figure 3 , Figure 7 and Figure 8 As shown, the inner frame snap-fit ​​structure 100 includes a plurality of inner frame hooks 101 distributed on the outer periphery of the inner frame 10, and a plurality of inner frame rings 102 surrounding the outer periphery of the middle frame 30. The outer frame snap-fit ​​structure 400 includes outer frame rings 401 corresponding to the inner frame hooks 101, and outer frame hooks 402 corresponding to the inner frame rings 102. The inner frame hooks 101 engage with their corresponding outer frame rings 401, and the outer frame hooks 402 engage with their corresponding inner frame rings 102.

[0072] The inner frame hook 101 and the outer frame hook 402 each form a hook portion. The hook portion of the inner frame hook 101 faces the center of the inner frame 10, and at least part of the hook portion of the outer frame hook 402 faces the outer peripheral edge of the outer frame 40. The hook portions of the inner frame hook 101 and the outer frame hook 402 are in opposite directions, which helps to ensure a stable connection between the inner frame 10 and the outer frame 40 and prevents them from loosening.

[0073] The inner frame retaining ring 102 and the outer frame retaining ring 401 each have through holes formed in the middle. The hook of the inner frame retaining hook 101 can be engaged in the through hole of the corresponding outer frame retaining ring 401, and the hook of the outer frame retaining hook 402 can be engaged in the through hole of the corresponding inner frame retaining ring 102.

[0074] When the inner frame 10 and the outer frame 40 are fastened together, the hook of the inner frame hook 101 and the corresponding outer frame ring 401 are pressed, deformed and misaligned against each other. When the hook of the inner frame hook 101 reaches the through hole of the outer frame ring 401, it can enter the through hole through the elastic recovery action to achieve the snap-fit. The hook of the outer frame hook 402 and the corresponding inner frame ring 102 are pressed, deformed and misaligned against each other. When the hook of the outer frame hook 402 reaches the through hole of the inner frame ring 102, it can enter the through hole through the elastic recovery action to achieve the snap-fit.

[0075] Furthermore, the hook portion of the inner frame hook 101 may be provided with a guide portion, which is a bevel or an arc surface, for guiding the hook portion of the inner frame hook 101 into the through hole of the corresponding outer frame retaining ring 401. The hook portion of the outer frame hook 402 may be provided with a guide portion, which is a bevel or an arc surface, for guiding the hook portion of the outer frame hook 402 into the through hole of the corresponding inner frame retaining ring 102.

[0076] Specifically, refer to Figure 3 From a certain perspective, the mounting opening 11 is a non-circular structure. The top of the mounting opening 11 is relatively close to the outer periphery of the inner frame 10, and the inner frame snap-fit ​​structure 100 and the outer frame snap-fit ​​structure 400 are also relatively close here. The bottom of the mounting opening 11 is relatively far from the outer periphery of the inner frame 10, and the inner frame snap-fit ​​structure 100 and the outer frame snap-fit ​​structure 400 are also relatively far apart here. To further strengthen the connection, the inner frame snap-fit ​​structure 100 also includes an inner frame retaining ring 102 arranged between the outer periphery of the inner frame 10 and the outer periphery of the middle frame 30. This inner frame retaining ring 102 is located below the mounting opening 11, and the inner side of the outer frame 40 is also provided with a corresponding outer frame hook 402.

[0077] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the outer side of the outer frame 40 forms a complete and smooth curved surface structure, which can improve the user's visual experience.

[0078] In some embodiments of this utility model, such as Figure 4 , Figure 6As shown, a positioning post structure for installation and positioning is provided between the inner side of the outer frame 40 and the inner side of the inner frame 10. The middle frame 30 is provided with a positioning hole 33, and the positioning post structure passes through the positioning hole 33 to install and position the middle frame 30. Specifically, the positioning post structure includes a positioning sleeve 13 disposed on the inner side of the inner frame 10 and a positioning post 44 disposed on the inner side of the outer frame 40. The positioning sleeve 13 is a cylindrical structure that can extend into the positioning hole 33, and the positioning post 44 is inserted into the positioning sleeve 13. When the middle frame 30 is installed on the inner side of the inner frame 10, the positioning sleeve 13 is inserted into the positioning hole 33 to limit the installation position of the middle frame 30. When the outer frame 40 is installed, the positioning post 44 is inserted into the positioning sleeve 13 to limit the relative position of the outer frame 40 and the inner frame 10. At this time, the inner frame snap-fit ​​structure 100 and the outer frame snap-fit ​​structure 400 can be positioned correspondingly, further installing the outer frame 40 into place, so that the corresponding inner frame snap-fit ​​and outer frame snap-fit ​​can be engaged with each other.

[0079] One or more positioning post structures can be provided between the inner side of the outer frame 40 and the inner side of the inner frame 10, and the positioning holes 33 are provided one-to-one with the positioning post structures.
