Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to an inner drum structure of a household washing machine. Background Art

[0002] The inner drum of a washing machine is one of the main structures of a washing machine, also known as a drain drum or a dehydration drum. The inner drum of a washing machine is mainly composed of a port ring, a drum body and a base. When in use, the inner drum can be rotated to wash and dehydrate the clothes. The inner drum filter box of a washing machine is a filter element installed at the drain outlet of the washing machine. Its main function is to collect garbage such as clothing fibers, cotton wool, and paper scraps washed off the clothes during the washing process, and filter these debris to prevent them from directly entering the drainage pipe, thereby protecting the drainage pipe.

[0003] In the prior art, the filter box of a pulsator washing machine is generally located on the side wall of the inner drum of the washing machine. A groove is provided on the side wall of the inner drum of the washing machine, and the filter box is fixed in the groove by snapping. However, although this snapping method has the advantage of being easy to operate, its connectivity is relatively weak in actual use. Especially during the washing process, the tumbling and friction of clothes in the washing machine often inadvertently scratch the filter box. This continuous impact and squeezing can easily loosen or even cause the filter box to fall out. Once the filter box falls out, the dirt accumulated inside it may scatter out, contaminating the clothes and causing unnecessary troubles to the user. In view of this, we propose an inner drum structure for a household washing machine. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] This embodiment provides a technical solution:

[0031] See also Figure 1-Figure 6The inner drum structure of a household washing machine includes a drum body 1, a base 2 is fixed at the bottom of the drum body 1, and a port ring 3 is fixed at the top of the drum body 1. Two symmetrical filter parts 4 are installed on the inner wall of the drum body 1; the filter part 4 includes a plate body 40 fixed to the inner wall of the drum body 1, an installation groove 401 is provided on the outer wall of the plate body 40, two slots 403 are provided at the bottom end of the installation groove 401, a card groove 402 is provided at the top of the installation groove 401, and two slide grooves 404 are provided on the front end surface of the plate body 40 located above the installation groove 401, and a slide hole 405 is provided at the top of the slide groove 404; a filter box 45 is inserted in the installation groove 401, and a plurality of water inlet grooves 451 are provided on the outer wall of the filter box 45, and the top ends of the filter box 45 Two fixing holes 453 are provided, a clamping head 454 is installed at the top center of the filter box 45, and the clamping head 454 is engaged with the card slot 402, and two plug blocks 452 are fixed to the bottom end of the filter box 45, and the plug blocks 452 are plugged with the slots 403; a slider 41 is slidably installed in the slide groove 404, a fixing rod 42 is fixed to the bottom end of the slider 41, and the fixing rod 42 is plugged with the fixing hole 453, a sliding rod 43 slidably connected to the sliding hole 405 is fixed to the top end of the slider 41, a spring 44 is provided above the sliding rod 43, and the spring 44 is fixed in the sliding hole 405.

[0032] In this embodiment, the slider 41, the slide bar 43 and the fixing bar 42 are an integrally formed structure, and the slider 41, the slide bar 43 and the fixing bar 42 are all made of plastic. The integrally formed structure improves the stability and durability of the overall structure, and the plastic material is light and reduces the overall weight. At the same time, the plastic has good plasticity and corrosion resistance, and is suitable for use in a humid washing machine environment.

[0033] In this embodiment, the size of the installation slot 401 is matched with the size of the filter box 45, and the filter box 45 is a plastic product. The matching size ensures that the filter box can be tightly installed in the installation slot, preventing dirt from leaking from the gap. The filter box made of plastic is also corrosion-resistant and suitable for use in a humid washing machine environment.

[0034] In this embodiment, the outer wall of the cylinder 1 is provided with a plurality of drainage holes 10, and the plurality of drainage holes 10 are distributed in a circular shape with equal spacing. The drainage holes 10 distributed in a circular shape with equal spacing ensure the uniformity of drainage and improve the drainage efficiency.

[0035] In this embodiment, a plurality of cavities 20 are formed at the bottom of the base 2, and the plurality of cavities 20 are radially distributed. The radially distributed cavity 20 increases the structural strength of the base 2, and improves its bearing capacity and stability.

[0036] In this embodiment, the outer wall of the slider 41 is provided with a plurality of ridges, and the plurality of ridges are linearly and evenly spaced from top to bottom. The ridges can increase the friction between the finger and the slider 41, thereby facilitating the slider 41 to be lifted or lowered.

[0037] In this embodiment, the plate body 40 is a product made of plastic material, and the plate body 40 is fixedly connected to the cylinder body 1 by bolts. The plate body is fixedly connected to the cylinder body by bolts, which ensures the stability of the plate body and facilitates installation and disassembly.

[0038] It should be added that a drainage groove is provided at the bottom of the mounting groove 401 in this embodiment, and the drainage groove is connected to the inner cavity of the washing machine; when water flows through the filter box 45, larger debris will be trapped on the outside by the screen, while clean water will continue to flow into the drainage pipe through the drainage groove; this is an existing conventional technology and will not be repeated here.

[0039] During specific use, the user first pushes the two sliders 41 on both sides upwards, and the sliders 41 drive the fixing rod 42 and the sliding rod 43 to move upwards. The spring 44 is compressed by the sliding rod 43 at the same time, and the fixing rod 42 is disengaged from the fixing hole 453 at this time. Then the user presses the clamping head 454 downwards and pushes the clamping head 454 to one side, and the clamping head 454 is disengaged from the clamping slot 402. At this time, the filter box 45 is disengaged from the installation slot 401, and the filter box 45 is removed.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
