Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a drying air duct structure and clothing processing equipment. Background Technology

[0002] Currently, most commercially available drying equipment is equipped with automatic filters to filter lint generated during the drying process, preventing it from entering the air duct or being released into the environment. These automatic filters mostly use oscillating brushes to clean the filter screen. However, such existing devices have the following drawbacks: due to the limited oscillation trajectory of the brushes, lint often accumulates at the edges of the brush's oscillation range after prolonged use. This accumulated lint is difficult for the brush to remove effectively, gradually forming dirt. As lint continues to accumulate, the brush's oscillation stroke may be obstructed, causing the brush to not fully cover the filter screen surface, resulting in a significant decrease in cleaning effectiveness. Lint accumulation on the filter screen also hinders airflow, reducing the filter's ventilation performance and consequently affecting the drying efficiency of the equipment, increasing energy consumption. Utility Model Content

[0003] In view of the technical problem that the brushes in the drying air duct are prone to accumulating and thus cannot operate properly in the existing technology, this utility model provides a drying air duct structure. By setting a position detection device, the working status of the cleaning device is monitored in real time. When the cleaning component cannot swing properly in place due to the accumulation of lint or other reasons, an alarm can be issued in time to remind the user to clean it.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] Reference Figures 1-4 These are some embodiments of the drying air duct structure of this utility model, which aim to solve the problem of reduced cleaning effect and drying efficiency caused by lint accumulation in the prior art.

[0036] The drying duct structure includes a duct housing 100, a filter element 200, a cleaning device, and a position detection device.

[0037] The air duct housing 100 forms a channel for the drying airflow, and a filter element 200 is installed inside it.

[0038] The filter element 200 is used to filter out debris such as lint in the drying airflow. It is usually made of a mesh structure or porous material and is removable for easy cleaning or replacement.

[0039] The cleaning device includes a cleaning component 310 and a drive mechanism 320. The cleaning component 310 is responsible for scraping the filter surface of the filter element 200, while the drive mechanism 320 drives the cleaning component 310 to oscillate. Figure 2 and Figure 3As shown, the cleaning assembly 310 has two extreme positions: a first extreme position and a second extreme position. The drive mechanism 320 drives the cleaning assembly 310 to oscillate back and forth between these two extreme positions, thereby scraping off the lint adhering to the filter element 200.

[0040] The position detection device is used to detect whether the cleaning component 310 has swung to the first and second limit positions, and outputs corresponding detection signals. These detection signals can be used to monitor the working status of the cleaning device and issue an alarm when the cleaning component 310 fails to reach the limit position, reminding the user to perform inspection and maintenance.

[0041] The aforementioned drying duct structure, through the installation of a cleaning device and a position detection device, can effectively remove lint from the filter element 200 and monitor the working status of the cleaning device in real time. When the cleaning component 310 fails to swing into position normally due to lint accumulation or other reasons, the equipment can promptly issue an alarm to remind the user to clean it, thereby avoiding the problem of reduced cleaning effect and drying efficiency caused by lint accumulation, and ensuring the continuous stability of drying performance.

[0042] In some embodiments, the position detection device includes at least two switches, namely a first switch 410 and a second switch 420. The first switch 410 is used to detect whether the cleaning component 310 has reached a first limit position, and the second switch 420 is used to detect whether the cleaning component 310 has reached a second limit position. When the cleaning component 310 reaches the corresponding limit position, it triggers the corresponding switch action, such as closing or opening a circuit, thereby generating a detection signal. The switches can be microswitches, proximity switches, Hall effect switches, etc.

[0043] Using a switch as a position detection device is simple in structure, low in cost, and highly reliable, and can effectively detect whether the cleaning component 310 has reached its limit position.

[0044] In some embodiments, the cleaning component 310 is provided with at least two contacts 3111, which correspond to and cooperate with the first switch 410 and the second switch 420, respectively. When the cleaning component 310 swings to the corresponding limit position, the contact 3111 contacts the corresponding switch and triggers the switch action. By providing the contact 3111 on the cleaning component 310, effective cooperation between the cleaning component 310 and the switch is achieved, ensuring the accuracy of position detection.

[0045] In other embodiments, the position detection device includes an angle sensor for detecting the swing angle of the cleaning assembly 310. The angle sensor can measure the swing angle of the cleaning assembly 310 in real time and convert the angle information into an electrical signal output. By monitoring changes in the swing angle, it can be determined whether the cleaning assembly 310 is working properly.

[0046] Using an angle sensor allows for more precise monitoring of the oscillation state of the cleaning component 310. It can detect not only whether the limit position has been reached, but also any abnormalities during the oscillation process, such as abnormal oscillation speed or midway stopping.

[0047] In some embodiments, the cleaning assembly 310 includes a brush arm 311 and a brush 312 fixed to the brush arm 311. The brush 312 is used to scrape the filter surface of the filter element 200, brushing off the lint attached thereto. The brush arm 311 is used to connect the brush 312 and the drive mechanism 320, and to drive the brush 312 to swing. Using the brush 312 as the cleaning assembly 310 can effectively remove lint from the filter element 200, and the structure is simple and easy to manufacture.

[0048] In some embodiments, an arc-shaped groove 110 is provided on the duct housing 100 to accommodate the swinging motion of the cleaning component 310. The shape and size of the arc-shaped groove 110 need to be precisely designed according to the swinging trajectory of the brush arm 311 and the size of the brush 312 to ensure that the brush 312 can effectively scrape the entire filter surface of the filter element 200 without interfering with the duct housing 100. The edges of the arc-shaped groove 110 can be chamfered or rounded to avoid scratching the brush arm 311 or causing noise.

[0049] The brush arm 311 is at least partially located outside the duct housing 100 for connection with the drive mechanism 320. The brush 312 is located inside the duct housing 100. The brush 312 is connected to the brush arm 311 via an arc-shaped groove 110 and oscillates along the trajectory of the arc-shaped groove 110. The arc-shaped groove 110 not only restricts the oscillation trajectory of the brush 312 but also provides support and guidance, ensuring stable and reliable oscillation of the brush 312.

[0050] The drive mechanism 320 includes a motor, a drive wheel 321 connected to the motor output shaft, and a driven gear 322 connected to the cleaning assembly 310. The drive wheel 321 meshes with the driven gear 322, converting the rotational motion of the motor into the oscillating motion of the cleaning assembly 310. The drive wheel 321 can be a gear, a pulley, or other type of transmission wheel. In this embodiment, the drive wheel 321 is a gear. To achieve reciprocating oscillation, in this embodiment, the reciprocating oscillation of the cleaning assembly 310 is achieved by controlling the forward and reverse rotation of the motor.

[0051] In some embodiments, a protective cover 500 is provided on the outside of the air duct housing 100. The protective cover 500 covers the outside of the brush swing arm 311 and the drive mechanism 320 to protect the internal drive mechanism 320.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
