Abstract
Description
Technical Field
[0001] The utility model relates to a filter bag detection device for a washing machine. Background Art
[0002] The washing machine filter bag is one of the parts of the washing machine, used to filter impurities at the outlet of the washing machine. Its structure is as follows Figure 1 As shown, it includes a bag body 1 and a flange 2. The filter bag is made of non-woven fabric and other materials through ultrasonic or hot-melt welding. It is inevitable that there may be problems with the welding at the weld. Therefore, the washing machine filter bag needs to be tested for weld strength before leaving the factory. The traditional test method is spot check flushing inspection, which randomly selects a certain number of filter bags, impacts the inside of the filter bag with high-pressure water for a certain period of time, and then checks whether the weld is cracked. Due to the use of high-pressure water for testing, the filter bag needs to be dried for a long time before it can be shipped after being wetted. Therefore, it is impossible to ensure that the filter bags leaving the factory are 100% qualified only by spot checks. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and provide a washing machine filter bag detection device.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A washing machine filter bag detection device comprises a machine base, on which a positioning seat adapted to a flange of a washing machine filter bag is arranged; an inflatable and deflable contoured airbag is arranged in the middle of the positioning seat, the inflated contoured airbag can open the bag body of the washing machine filter bag, an air pump is connected to the contoured airbag via a pressure regulating valve to inflate and deflate the contoured airbag; a clamp is arranged above the positioning seat, the clamp has a U-shaped opening adapted to a flange of the washing machine filter bag, one end of the clamp extends out and is connected to the machine base via a connecting rod structure, a handle is connected to the connecting rod structure and can drive the connecting rod structure to link the clamp to press down on the flange or release the flange.
[0006] In another preferred embodiment, a control panel is further provided on the machine base, and the control panel is inclined relative to the plane where the positioning base is located.
[0007] In another preferred embodiment, a positioning protrusion for positioning the flange is provided on the positioning seat.
[0008] The beneficial effect of the utility model is that, since a contoured air bag is used to simulate the pressure of water flow on the filter bag, it is possible to quickly detect whether the filter bag is broken or not. The pre-shipment test is performed by the waterless detection method, which improves the test efficiency and realizes 100% detection of the filter bag.
[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments; however, the washing machine filter bag detection device of the present invention is not limited to the embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the structure of a washing machine filter bag.
[0011] Figure 2 It is a structural schematic diagram of a preferred embodiment of the utility model. DETAILED DESCRIPTION
[0012] For example, see Figure 1 and Figure 2 As shown, a washing machine filter bag detection device of the utility model includes a base 3, on which a positioning seat 4 is provided for fitting a flange 2 of a washing machine filter bag; an inflatable and deflable contoured airbag 5 is provided in the middle of the positioning seat 4, and the inflated contoured airbag 5 can open the bag body 1 of the washing machine filter bag, and an air pump is connected to the contoured airbag 5 through a pressure regulating valve 6 to inflate and deflate the contoured airbag 5; a clamp 7 is provided above the positioning seat 4, and the clamp 7 has a U-shaped opening for fitting a flange of a washing machine filter bag, one end of the clamp 7 extends out and is connected to the base 3 through a connecting rod structure 8, and a handle 9 is connected to the connecting rod structure 8 and can drive the connecting rod structure 8 to link the clamp 7 to press down on the flange 2 or release the flange 2.
[0013] The base 3 is also provided with a control panel 10 , which is inclined relative to the plane where the positioning base is located. The control panel 10 is provided with buttons 11 and a display screen 12 .
[0014] The positioning seat 4 is provided with a plurality of positioning protrusions 13 for positioning the flange 2 , and the positioning protrusions 13 are used for positioning the notch 14 on the flange 2 .
[0015] The detection device of this embodiment adjusts the regulating valve 6 before use so that the air pressure entering the profiling airbag 5 reaches the specified value. When starting the test, the bag body 1 is covered with the profiling airbag 5 and the handle 9 is operated to make the clamp 7 press the flange 2 of the filter bag. Press the start button and the profiling airbag 5 starts to inflate. Since the profiling airbag 5 imitates the shape of the filter bag, it will fill the inner side of the bag body 1 after inflation to simulate the pressure of water flow on the filter bag. After a period of inflation, the electronic control automatically starts to deflate, and the washing machine filter bag is removed to check whether there is any rupture or defect, and the detection is completed.
[0016] This embodiment uses a contoured airbag to simulate the pressure of water flow on the filter bag, which can quickly detect whether the filter bag is broken or not. The pre-shipment test is performed through this waterless detection method, which improves the test efficiency and realizes 100% detection of the filter bag.
