Description

Technical Field

[0001] This invention relates to the field of clothing processing devices, and more particularly to a clothing processing device and its gate. Background Technology

[0002] Currently, commonly used drum washing machines consist of an outer shell including a control panel, inner and outer drums, and a washing machine door. The washing machine door consists of a door frame and an observation window. The drawback of this structure is that the inner drum is relatively dark, and the internal condition cannot be clearly seen through the observation window. This makes it difficult for consumers to understand the performance of the drum washing machine, and they cannot monitor the washing status at any time during use.

[0003] The invention patent with application number CN201610193426.2 discloses a washing machine door with a decorative ring, including a time display module, a light strip, a control device, and a middle frame. The time display module, the light strip composed of LED beads, and the control device are mounted on the middle frame. An installation frame is provided above the middle frame, and the time display module is installed in the installation frame. It also includes a decorative ring with a shape adapted to the middle frame. The decorative ring includes a film layer and a substrate. The substrate includes an area corresponding to the time display module as a time display area and the remaining area as a light display area. The light transmittance of the decorative ring in the time display area is greater than that in the light display area. It also relates to a washing machine and a washing method using the door. When the washing machine is powered on, the user can observe the light of the time display module and the light strip, but cannot see the LED beads. When the washing machine is not powered on, the time display module and the light strip are hidden.

[0004] Although the invention features an aesthetically pleasing decorative ring that displays the washing machine's running time or status, it lacks a lighting device within the door structure to illuminate the door and the inside of the drum. Users cannot clearly see the inside of the drum through the viewing window, making it impossible to understand the performance of the drum washing machine and thus reducing the user experience.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0057] The first connecting rib strengthens the overall structure of the inner frame 13. Similarly, the second connecting rib strengthens the overall structure of the middle frame 12. The connecting rib is equipped with a protruding structure 22 and a groove 23, which not only strengthens the overall structure of the door 1, but also allows the fixing part 35 to better secure the observation window 10, ensuring the stability of the observation window 10 in the structure of the door 1.

[0058] Another object of the present invention is to provide a clothing handling device employing the door 1 as described above.

[0059] Example 1

[0060] like Figure 1-5 As shown, the clothing processing device in this embodiment can be a drum washing machine.

[0061] The drum washing machine includes a door 1, a control panel 3, a cabinet 2, an inner drum 4, and a window gasket 5. The door 1 includes an observation window 10, a fixing frame, and a lighting device 38. The fixing frame, which is used to fix the observation window 10, includes an outer frame 11, an inner frame 13, and a middle frame 12. The lighting device 38 is installed on the middle frame 12 to illuminate the observation window 10. The lighting device 38 on the middle frame 12 of the door 1, while ensuring reliability, can effectively provide synchronous illumination for both the door 1 and the inner drum 4, allowing for better observation of the inner drum 4's operation and improving the user experience. The observation window 10 can be made of any transparent material, such as glass.

[0062] Furthermore, the middle frame 12 is an annular frame structure connecting the outer frame 11 and the inner frame 13.

[0064] like Figure 4 and 5 As shown, a second support structure 29 extending towards the inner frame 13 is provided on the outer periphery of the main body 25 of the middle frame. This second support structure 29 can not only contact the outer frame 11 and the inner frame 13 at the same time and abut against the inner wall of the outer frame 11 and the inner wall of the inner frame 13, but also support the outer frame 11 and the inner frame 13 from the inside of the door body 1 while ensuring the support of the middle frame 12 itself, effectively ensuring the firmness of the entire fixed frame.

[0065] like Figure 4 and 5 As shown, correspondingly, at least one third support structure 30 is provided on the inner peripheral wall of the outer frame 11 in the direction of the middle frame 12. The third support structure 30 can strengthen the strength of the outer frame 11. After the fixed frame is installed, the third support structure 30 is in contact with the low-step structure 27 of the middle frame 12. The third support structure 30 and the first support structure 27 provide good mutual support between the outer frame 11 and the middle frame 12.

[0066] It is understood that, to enhance its robustness and stability, the inner frame 13 may have at least one fourth support structure 31 located on its inner peripheral wall towards the middle frame 12. This fourth support structure 31 may or may not be in contact with the inner frame 13. The lighting device 38 is disposed on the inner peripheral wall of the clamping and fixing part 3514.

[0068] The lighting device 38 is set on the inner peripheral wall of the fixing part 35 of the middle frame 12, which ensures reliability and firmness while providing better lighting effect. In particular, the lamp assembly 15 is set with a preset angle according to the structure of the observation window 10 and the middle frame 12, so that the light is better focused into the inner cylinder 4, improving the utilization rate of light and making the lighting effect more prominent.

[0069] Furthermore, the lighting device 38 also includes a lamp holder 16 disposed on the inner peripheral wall of the middle frame 12, and the lamp assembly 15 is mounted on the lamp holder 16. Preferably, the lamp holder 16 is snap-fitted to the inner peripheral wall of the middle frame 12. It is understood that the connection between the lamp holder 16 and the middle frame 12 is not limited to snap-fitting, but can also be integrally formed, bolted 32 connected, etc., and is not limited here.

[0070] Furthermore, the door 1 is connected to the housing 2 of the garment processing device via a door hinge 17. Preferably, the door hinge 17 forms a lead-through channel for the wiring harness of the lighting device 38. The wiring harness passes through the lead-through channel through the housing 2 and connects to the control unit and / or power supply inside the garment processing device, saving wiring harness consumption, optimizing the wiring harness layout, and improving aesthetics.
