Description

Technical Field

[0001] This utility model belongs to the field of drum washing machine technology, and more specifically, it relates to a filter device for drum washing machines. Background Technology

[0002] A drum washing machine is a common household appliance. Its design principle is based on simulating the tumbling and rubbing motions of traditional hand washing. The filter in a drum washing machine is mainly used to capture and filter debris such as lint, thread, and buttons generated during the washing process to prevent these substances from clogging the drainage system or affecting the normal operation of the washing machine.

[0003] According to application number CN201720893146.2, a drum washing machine is disclosed. This utility model aims to solve the problem of excessively large dimensions, especially thickness, in existing large-capacity washing machines. To this end, the drum washing machine of this utility model includes a cabinet and a washing drum and a drive device housed within the cabinet. The cabinet's width is greater than its thickness. Furthermore, a recess is provided at the rear of the washing drum, and at least a portion of the drive device is housed in the recess and directly connected to the washing drum for driving its rotation. Through this structural design, space within the cabinet is effectively saved, reducing the depth dimension of the drum washing machine, resulting in a wide-body, ultra-thin design that significantly reduces the floor space required.

[0004] Based on the above, when the existing drum washing machine filter needs cleaning, the filter is often installed on the inner side of the washing machine through a threaded connection, which makes the disassembly process cumbersome and affects work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a filter device for drum washing machines. This addresses the issue that existing drum washing machine filter devices, which are often installed on the inner side of the washing machine via threaded connections, are cumbersome to disassemble, thus affecting work efficiency.

[0006] The purpose and effect of this utility model's filter device for drum washing machines are achieved through the following specific technical means: A filter for a drum washing machine includes a washing machine body, a fixed housing, a washing drum, a washing machine door, a pull-out box, a control panel, a hinged cover, a filter element, a sealing gasket, a filter screen, an installation mechanism, and a limiting mechanism. The fixed housing is fixedly connected to the inside of the washing machine body. The washing drum is rotatably mounted on the inside of the washing machine body. The washing machine door is hinged to the front end of the washing machine body. The pull-out box is slidably connected to the inside of the upper end of the washing machine body. The control panel is mounted on the upper end of the washing machine body. The hinged cover is hinged to the front end of the fixed housing. The filter element is inserted into the inside of the lower end of the washing machine body. The sealing gasket is slidably connected to the outside of the filter element. The filter screen is mounted on the inside of the lower end of the washing machine body. The installation mechanism is located inside the filter element. The limiting mechanism is located inside the washing machine body.

[0007] Furthermore, the installation mechanism includes: an installation plate, an installation rod, an installation block, and a fixing compression spring; the installation plate is inserted into the inner side of the filter element; the installation rod is fixedly connected to the outer side of the installation plate; there are two installation blocks, both of which are slidably connected to the inner side of the installation rod; the fixing compression spring is fixedly connected to the inner side of the two installation blocks.

[0008] Furthermore, the installation mechanism also includes a cleaning sleeve; the cleaning sleeve is slidably connected to the outside of the filter element.

[0009] Furthermore, the limiting mechanism includes: a limiting groove, a limiting block, and a limiting compression spring; the limiting groove is opened on the outside of the filter element; the limiting block is slidably connected to the inside of the fixed housing; there are two limiting compression springs, one end of each limiting compression spring is fixedly connected to the outside of the limiting block, and the other end of each limiting compression spring is fixedly connected to the inside of the fixed housing.

[0010] Furthermore, the limiting mechanism also includes: a fixed shaft, a synchronous pulley, and a synchronous transmission belt; there are two fixed shafts, both of which are fixedly connected to the outer side of the rear end of the hinged cover plate; there are two sets of synchronous pulleys, both of which are rotatably connected to the inner side of the fixed housing, and the lower synchronous pulley is fixedly connected to the fixed shaft.

[0011] Furthermore, the limiting mechanism also includes: a connecting shaft, a fixing block, and a connecting cam; the connecting shaft is fixedly connected to the outside of the limiting block; there are two fixing blocks, which are respectively fixedly connected to both ends of the connecting shaft; there are two connecting cams, which are rotatably connected to the inside of the fixed housing, and the two connecting cams are respectively fixedly connected to the two upper synchronous pulleys.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model achieves convenient installation of the filter element through the installation mechanism. The cleaning sleeve is slidably fitted onto the outside of the filter element, and then the installation rod is inserted into the inside of the filter element. Under the elastic action of the fixed compression spring, the installation block automatically engages inside the filter element, completing the fixed installation of the cleaning sleeve. After installation, the entire filter element can be inserted into the fixed housing for operation. When cleaning is required, the cleaning sleeve can be directly removed for replacement, simplifying operation and significantly improving maintenance efficiency. The limiting mechanism enables quick disassembly and assembly of the filter element. When the hinged cover is opened, it drives the same... The rotating pulley drives the synchronous pulley to rotate synchronously under the transmission of the synchronous belt. The rotation of the connecting cam pushes the fixed block to slide upward. This movement is transmitted through the connecting shaft, causing the limit block to move upward and disengage from the limit groove on the filter element. At this time, the filter element loses its limit constraint and can be easily disassembled or installed, simplifying the operation process, improving work efficiency, and effectively reducing labor intensity. Through the above mechanism, not only is reliable installation and quick disassembly of the filter element achieved, but the convenience of equipment maintenance is also greatly improved, effectively increasing work efficiency and reducing the operating burden.
