[0033] Based on the above purpose, the first aspect of the present invention provides an embodiment of a washing machine panel water tightness testing device, such as Figure 1 , Figure 2 As shown, including:

[0034] A base 1, wherein the upper end surface of the base 1 is provided with a plurality of detection slots 2 penetrating the side surface thereof;

[0035] The upper end surface is provided with a support block 5 for placing the groove 13, and at least two support blocks 5 are provided in the detection groove 2 for supporting the lower panel of the washing machine;

[0036] A first cylinder 3 and an extension rod 4 are fixed to the upper end surface of the base 1 by a fixing member, the extension rod 4 corresponds to the detection slot 2 one by one, and the extension rod 4 is located directly above the corresponding detection slot 2, the output shaft side surface of the first cylinder 3 is fixedly connected to one end of the extension rod 4, and a pressure block is provided below the side surface of the extension rod 4 for applying pressure to the upper panel of the washing machine so that the upper panel of the washing machine is combined with the lower panel of the washing machine;

[0037] A linkage plate 11 is arranged on the outer side of the detection groove 2, a water injection nozzle 12 is fixed to the linkage plate 11, and a driving part is arranged in the base 1, the water injection nozzle 12 is directly opposite to the detection groove 2, and the water injection nozzle 12 is connected to the water pump through a water pipe, and the driving part is connected to the linkage plate 11, and is used to drive the linkage plate 11 to drive the water injection nozzle 12 to connect with the water injection port of the washing machine panel.

[0038] As an implementation mode, during the inspection, the lower panel of the washing machine is first placed on the placement groove 13 of the support block 5 of each inspection groove 2 in turn, and then the upper panel of the washing machine is buckled with the bottom of the washing machine. After completion, the first cylinder 3 is started to drive the extension rod 4 to move in the direction of the inspection groove 2, and finally a certain pressure is created between the pressure block and the upper panel of the washing machine, so that the upper panel of the washing machine and the lower panel of the washing machine are pressed tightly, and then other outlets of the washing machine panel are blocked, leaving the water injection port unobstructed. At this time, the driving part is activated to make the linkage plate 11 move toward the base 1. When the water injection nozzle 12 is combined with the water injection port of the washing machine panel, the driving part stops moving, and the water pump starts to inject water into the washing machine panel. After reaching a certain pressure, the water pump stops injecting water, and after a period of time, the test is completed. At this time, the extension rod 4 and the linkage block are restored to their original positions, and the washing machine panel can be removed. Through this device, multiple washing machine panels can be tested for water tightness at one time, thereby improving the inspection efficiency.

[0039] As an implementation method, Figure 1 and Figure 2 As shown, it also includes a connecting rod 14 and a first pressure sensor 15 fixed to one end of the connecting rod 14, and the other end of the connecting rod 14 is fixed to the end surface of the water injection nozzle 12 facing the detection tank 2. In this way, the first pressure sensor 15 can sense the pressure change in the washing machine panel during detection, so as to conveniently judge the water tightness.

[0040] As an implementation method, Figure 1 , Figure 2 and Figure 3 As shown, the driving unit includes:

[0041] A bottom hole 7 is provided on the lower end surface of the base 1, a chassis 9 is located at the bottom hole 7, and a first motor 6 whose output shaft is fixed at the center of the chassis 9, and the first motor 6 is fixed to the lower end surface of the base 1 through a fixing member;

[0042] A side hole 8 is provided on the side surface of the base 1, the side hole 8 corresponds to the linkage plate 11 one by one, and the side hole 8 is connected to the bottom hole 7;

[0043] A driving plate 10 is slidably connected to the side hole 8, and one end of the driving plate 10 is fixed to a linkage plate 11. The lower surface of the linkage plate 11 is provided with a first thread, and the upper surface of the chassis 9 is provided with a second thread, and the first thread is meshed with the second thread.

[0044] In this embodiment, when the first motor 6 drives the chassis 9 to rotate, the driving plate 10 can slide in the side hole 8 due to the engagement of the first thread and the second thread.

[0045] As an implementation method, Figure 4As shown, the second pressure sensor 16 is also included. The side wall of the detection slot 2 facing the linkage plate 11 is provided with the second pressure sensor 16. Here, when the lower panel of the washing machine is placed, one section of the lower panel is in contact with the side wall of the detection slot 2 facing the linkage plate 11. When the second pressure sensor 16 senses the pressure, the lower panel of the washing machine is placed on the support block 5. In this way, when the water pump is filling water, the water injection nozzle 12 can be prevented from being separated from the water injection port due to excessive pressure of the water injection.

[0046] As an implementation method, Figure 1 , Figure 2 , Figure 4 As shown, it also includes:

[0047] A slide groove 19 is provided in the detection groove 2 and a slide plate 18 is slidably connected to the slide groove 19, and the support block 5 is fixed to the corresponding slide plate 18;

[0048] An adjusting portion for driving the slide plate 18 to slide.

[0049] Here, before the pressure block applies pressure to the upper panel of the washing machine, the sliding plate 18 is driven by the adjusting part to move in the direction of the second pressure sensor 16. When all the second pressure sensors 16 feel the pressure, the adjusting part stops driving, thereby ensuring that all the lower panels of the washing machine are in contact with the side wall of the detection slot 2 facing the linkage plate 11.

[0050] As an implementation method, Figure 4 As shown, the adjustment unit includes:

[0051] An inner hole 21 is provided in the base 1, and the inner hole 21 is communicated with the slide groove 19;

[0052] A second motor 17 fixed above the inner hole 21 and a reel 23 fixed to the second motor 17, the reel 23 being located in the inner hole 21, and the reel 23 being provided with reel grooves corresponding to the slide grooves 19 one by one;

[0053] A pull rope 22 with one end fixed to one end of the slide plate 18, and the other end of the pull rope 22 is fixed to the corresponding winding groove;

[0054] A spring 20 is located in the slide slot 19 , with one end of the spring 20 fixed to the slide plate 18 and the other end fixed to the side wall of the slide slot 19 .

[0055] Here, when the second motor 17 is started and drives the winding wheel 23 to wind up the pull rope 22, the slide plate 18 can overcome the elastic force of the spring 20 and move toward the side wall of the detection slot 2 toward the linkage plate 11. When all the lower panels of the washing machine are in contact with the side wall of the detection slot 2 toward the linkage plate 11, the second motor 17 stops driving. After the detection is completed, the second motor 17 releases the pull rope 22, so that the slide plate 18 returns to its original position.
