Description

Technical Field

[0001] The utility model relates to the technical field of filter boxes, and more specifically to a filter box for a dryer that is convenient for maintenance. Background Art

[0002] The filter box of a dryer is a key component designed to improve the safety, efficiency, and service life of the device. Its main function is to capture fibers, cotton fluffs, and other tiny particles that fall off during the drying process, maintain the air circulation in the dryer, avoid efficiency reduction caused by blockage, and effective filtration can prevent cotton fluffs from accumulating inside the dryer, reduce the maintenance frequency, and extend the device life. In the early dryer designs, the problem of cotton fluff and fiber accumulation was not fully emphasized. Cotton fluffs and fibers would accumulate in the ventilation openings and exhaust systems inside the dryer during the drying process. These accumulated cotton fluffs are flammable and may cause fires. With the popularization of household appliances, users have higher and higher requirements for the convenience and maintenance of dryers. The filter box of a dryer enables users to easily clean and maintain the device, improving the convenience and comfort of use.

[0003] Deficiencies of the prior art: Some filtering devices may not be able to capture very fine cotton fluffs and fibers, especially when operating at high loads or for long periods. Fine cotton fluffs may still enter the dryer interior. The design of some devices may make the cleaning and replacement of the filter screen complicated or inconvenient, increasing the maintenance difficulty and time cost for users. Some filtering devices may age or be damaged in high-temperature and high-humidity environments, resulting in a decline in filtration efficiency or the need for frequent replacement. If the filter screen accumulates too much cotton fluff, it may impede air flow, thus affecting the energy efficiency and drying performance of the dryer, increasing energy consumption. Although the filtering device reduces cotton fluff accumulation, it still needs to be cleaned regularly. Otherwise, the accumulated cotton fluff may still pose a fire hazard.

[0028] The working principle of the present utility model: A cavity 106 is designed inside the filter box 1, and inside the cavity 106, through a fixing frame 107

[0029] A metal screen filter 108 and a polyester filter 109 are installed. When the dryer is working, the generated gas may contain impurities such as cotton fluffs, fibers, and tiny particles. These impurities enter the filter box 1 through the interface 101. First, the metal screen filter 108 serves as the primary filter and can intercept larger cotton fluffs and fiber particles. Subsequently, the gas passes through the polyester filter 109 to further filter out tiny particles and impurities, ensuring that the finally discharged gas is clean and pollution-free. The ventilation holes 104 opened on the side of the hinged door 103 allow the gas to pass smoothly, while maintaining a certain ventilation effect to prevent excessive internal pressure. A fixing buckle 3 is fixed on the side of the filter box 1. A snap ball 305 is movably connected in the snap hole 301 on the fixing buckle 3. When it is necessary to disassemble the filter box 1 for cleaning or replacing the filter, the user only needs to gently press or rotate the snap housing 303 to make the snap ball 305 disengage from the snap hole 301 under the action of the spring 304, and then the filter box 1 can be easily removed. This design does not require any tools, simplifies the operation steps, and reduces the maintenance difficulty. A magnet 111 is also fixed on the side of the filter box 1 to assist in fixing the hinged door 103 or the hinged cover door 201 to ensure that they are more stable when closed and prevent accidental opening during the operation of the dryer. Through the effective filtration system, the blockage and wear of the internal components of the dryer by impurities are reduced, ensuring smooth air circulation, thereby improving the drying efficiency and shortening the drying time. The metal filter box 1 and the filter can withstand the high temperature of the gas discharged from the dryer, reducing the accumulation of flammable substances such as cotton fluffs in the pipeline and reducing the fire risk caused by high temperature.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
