Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dryer components, in particular to a magnet detection device for a filter handle of a dryer. Background Art
[0002] A clothes dryer is a household cleaning appliance that uses electric heating to instantly evaporate the moisture in washed clothes. It has a filter handle inside that is equipped with a magnet that works in conjunction with the door magnetic switch inside the dryer. When installing the magnet, it is easy to install it upside down or not in place. The magnet is very small and difficult to detect after installation, resulting in the quality of the product leaving the factory cannot be guaranteed. Summary of the Invention
[0003] In order to solve the above technical problems, the utility model provides a magnet detection device for a filter handle of a clothes dryer, which can quickly and conveniently detect whether the door magnetic switch is installed upside down or in place, thereby ensuring product quality.
[0004] The technical solution is as follows: a magnet detection device for a filter handle of a clothes dryer, characterized in that it includes a workbench, a positioning frame is installed on the workbench through a support column, a detection notch is opened on one side of the positioning frame, a door magnetic switch is installed in the detection notch, a lifting platform is provided below the positioning frame, and the bottom of the lifting platform is connected to a lifting cylinder.
[0005] It is further characterized in that an opening larger than the lifting platform is provided on the workbench, a cylinder fixing seat is installed at the bottom of the workbench, and a cylinder body of the lifting cylinder is fixed to the cylinder fixing seat;
[0006] The door magnetic switch is installed in the detection gap by means of bolts;
[0007] The top of the lifting platform is an inclined surface and limit stop bars are arranged on both sides, and a limit groove is arranged inside the limit stop bar at the inclined lower end.
[0008] After adopting the utility model, the bottom of the filter handle to be tested passes through the positioning frame and is supported on the lifting platform, and the upper part is positioned by the positioning frame. At this time, the magnet is aligned with the door magnetic switch. By lifting the filter handle and detecting whether the door magnetic switch is turned on within the set height, it can be determined whether the magnet is installed upside down or in place, thereby ensuring the quality of the product.

[0014] See Figures 1 to 5 As shown, a magnet detection device for a filter handle of a clothes dryer includes a workbench 1, a positioning frame 3 is installed on the workbench 1 through a support column 2, a detection notch 4 is opened on one side of the positioning frame 3, a door magnetic switch 5 is installed in the detection notch 4, a lifting platform 6 is provided below the positioning frame 3, and a lifting cylinder 7 is connected to the bottom of the lifting platform 6. Specifically, an opening larger than the lifting platform 6 is opened on the workbench 1, a cylinder fixing seat 8 is installed at the bottom of the workbench 1, and the cylinder body of the lifting cylinder 7 is fixed to the cylinder fixing seat 8.
[0015] The door magnetic switch 5 is installed in the detection gap 4 by means of bolts 9, and can be easily replaced.
[0016] The top of the lifting platform 6 is an inclined surface and limit bars 12 are set on both sides, and a limit groove 10 is set inside the limit bar 12 at the inclined lower end, which can effectively limit the filter handle 11 to complete the positioning.
[0017] The detection principle is as follows: the lower part of the filter handle 11 to be detected is passed through the positioning frame 3 and supported on the lifting platform 6, and is positioned by the limit stop bar 12 and the limit groove 10. The upper part of the filter handle 11 is positioned by the positioning frame 3. At this time, the installation position of the magnet is opposite to the detection notch 4. The door magnetic switch 5 contains two magnetic reeds, which remain separated when there is no magnetic field. When a magnet approaches, it will be closed and connected. The door magnetic switch 5 is connected to the indicator light and the buzzer. As long as the distance between the door magnetic switch and the magnet is within the set range, the door magnetic switch 5 is always in the closed state, the indicator light can be turned on and the buzzer can be sounded. By lifting the lifting platform 6 to raise the filter handle 11, the distance between the magnet and the door magnetic switch 5 changes, thereby determining whether it is working normally within the set range; when the magnet is installed upside down or not installed in place, the door magnetic switch 5 cannot be closed or no abnormality occurs within the set range, and the indicator light and the buzzer do not work; the operator can easily understand the installation status of the magnet.
