The structure of the above-mentioned grooved anti-cone coupling mechanism is shown in FIG. Make it slide toward one direction of the main body 101 (the left direction in FIG. 5 ), and fasten it on the edge of the hole 107 , so that the operation panel 103 is installed on the main body 101 .

However, when the above-mentioned existing washing machine falls during transportation, a strong force in the up and down direction will be added to the operation panel 103, so the folding claw 106 will also be added to the horizontally long L-shaped clamping claw 106. There is a problem that there is a possibility of breaking due to bending momentum.

One way to solve the above problem is to increase the thickness of the clamping claws 106 . However, in this way, the thickness in the vertical direction will be increased, the internal volume of the operation panel 103 will be reduced, and the operation board must be reduced.

In addition, in order to improve the strength, a method of fixing the upper and lower parts of the operation panel 103 with screws may also be adopted. However, since the lower screw fixing part is close to the opening 102, chemicals such as washing powder dripping from the laundry when putting in/taking out the laundry are easy to penetrate, and such chemicals will cause a decrease in strength. In order to suppress such a decrease in strength to a minimum, it is necessary to take measures such as increasing the size of the fastener, and there arises a problem that design and manufacture become difficult.

In addition, in order to hide the heads of the screws, the exterior parts 105 must be fixed to the washing machine body 101 with screws, which is very difficult to assemble.

In addition, a body mounting surface 18 protruding toward the operation panel 3 side is provided in the concave portion 1 b of the washing machine body 1 . In this way, when the operation panel 3 is mounted in the recess 1b of the washing machine body 1, a part of the recess 1b of the washing machine body 1 approaches or bears against the back surface of the control circuit board mounting plate 3c in a substantially parallel state.

Next, a method for installing the operation panel 3 in the above-mentioned configuration into the recessed portion 1b of the washing machine body 1 will be described. First, the rear surface of the control circuit board mounting plate 3c is slid on the body mounting surface 18, and while the operation panel 3 is moved from above to below, the third protruding piece 16 is inserted into the opening hook hole 17, thereby The operation panel 3 is installed on the washing machine body 1 . At this time, the front surface 16a of the third protruding piece 16 approaches or abuts on the front end edge 17a of the opening hooking hole 17 . In addition, the lower end portion 3aa of the operation display portion 3a of the operation panel 3 bears against or approaches the lower inner surface 1bb of the concave portion 1b of the washing machine body 1 (see FIG. 3 ).

Moreover, the protrusion pin 15a of the 2nd protrusion part 15 of the washing machine body 1 penetrates and inserts into the 2nd through-hole 13a of the 2nd protrusion piece 13, and is positioned. At this time, the positions of the first through hole 12a of the first protruding piece 12 and the screw hole 14a of the first boss portion of the washing machine body 1 are aligned with each other.

In this state, the operation panel 3 is fixed to the washing machine body 1 by inserting the screws 19 into the first through holes 12a from above and tightening them into the screw holes 14a.

In addition, the washing machine body 1 is provided with a plurality of substantially flat hooking surfaces 20 extending rearward near the upper end thereof. Correspondingly, hooking portions 21 extending forward are respectively provided on the top plate 4 at positions corresponding to the substantially flat hooking surface portions 20 ( FIG. 3 ).

After the operation panel 3 is fixed on the washing machine body 1 as described above, the upper surface of the hooking portion 21 of the top plate 4 is inserted into the underside of the substantially flat hooking portion 20 in the washing machine body 1, and then passed The rear surface of the top plate 4 is fixed on the rear surface of the washing machine body 1 with screws (not shown), so that the top plate 4 is fixed on the washing machine body 1 .

In addition, by setting the upper triangular protrusions on the parts that do not affect the connection with other parts in the first protruding piece 12, the second protruding piece 13, the third protruding piece 16, the hooking surface 20 and the hooking part 21 Ribs such as ribs or four-corner ribs are expected to increase their own strength.

After adopting the present embodiment 1 described above, when the operation panel 3 is installed on the washing machine body 1, the screw 19 passes through the first through hole 12a on the first protruding piece 12 and is tightened on the first boss portion 14. On the screw hole 14a, and since the screw 19 extends in a direction approximately vertical to the ground (that is, approximately in a vertical direction) when the washing machine is stood upright, if the product falls in an upright state during transportation, it will be more The force in the axial direction of the screw 19 is a lot, but the force applied in the shear direction is less, so the thickness of the first boss portion 14 can be easily improved without increasing the thickness. At the same time, since the installation position of the operation panel 3 will not be deflected, there will be no gap around the operation panel 3, thereby preventing foreign matter from entering the body.

In addition, since the protruding pin 15a of the second protruding column portion 15 of the washing machine body 1 is inserted and locked in the second through hole 13a provided on the second protruding piece 13 of the operation panel 3, and the protruding pin 15a is in the When the washing machine stands upright, it extends in a direction approximately vertical to the ground (i.e. approximately in a vertical direction). Therefore, even if the product falls in an upright state during transportation, it will be added to the protruding pin 15a of the washing machine body 1. The force in the shearing direction is less, so that the protruding pin 15a will not break and the installation position of the operation panel 3 will not deviate. Moreover, there is no gap near the operation panel 3 here, and foreign matter does not enter the inside of the body.

In addition, since the first protruding piece 12 on the operation panel 3 and the first boss portion 14 on the washing machine body 1 are located near the substantially flat hooking surface 20 on the washing machine body 1, the second protruding piece 13 and The 2nd boss portion 15 is positioned at the vicinity of the substantially flat hooking surface 20 on the top plate 4, and the upper surface of the hooking portion 21 is positioned below the lower surface of the hooking surface 20, so the impact when the product falls is even The top plate 4 is greatly deformed, but because the transmission of power from the top plate 4 to the washing machine body 1 is carried out from below to the top, so the force added to the compression direction of the screw 19 is more, and the protruding pin 15a And the insertion part of the second through hole 13a is also added with more force in the abutting direction, so the movement of the fixed operation panel 3 is very little, and the force between the operation display part 3a and the operation part main body 3b is relatively small. There are also very few phases. In this way, the hook fit between the upper fixing claw 6 of the operation display part and the upper hole 7 of the operation part main body, and between the fixing claw 8 of the operation display part and the lower hole 9 of the main body of the operation part will not fall off, and the surrounding area of the operation panel 3 There will be no gaps, and no foreign matter will enter the body.

In addition, since the back side of the top plate 4 is set close to the second protruding piece 13 of the operation panel 3, even if the top plate 4 and the washing machine body 1 are deformed due to the impact when the product is dropped, the movement of the second protruding piece 13 will not change. Restricted by the top plate 4 and the washing machine body 1, the protruding pin 15a is not easy to fall off from the second through hole 13a, so that the operation panel 3 can be reliably fixed. In addition, since the first protruding piece 12, the screw 19, the second protruding piece 13 and the protruding pin 15a on the operation panel 3 will be blocked by the top plate 4, there is no need to increase other parts for covering these components. There will be no increase, and the assembly operation will become easier.

In addition, since one side of the operation panel 3 is provided with a protruding body mounting surface 18, when the operation panel 3 is installed in the concave portion 1b of the washing machine body 1, a part of the concave portion 1b of the washing machine body 1 is substantially parallel. The state is close to or against the back side of the control circuit board mounting plate 3c. Therefore, when the operating panel 3 is installed in the recess 1b of the washing machine body 1, it is only necessary to slide the operating panel 3 from top to bottom on the body mounting surface 18. Just can make the 2nd through hole 13a and protruding pin 15a, and make the 3rd protruding piece 16 and opening hook hole 17 combine. In this way, alignment between the first through hole 12a and the screw hole 14a is unnecessary, and assembly can be facilitated.

In addition, since the position where the screw 19 passes through the first through hole 12a and is tightened in the screw hole 14a to realize screw fastening is far away from the opening portion 2, the detergent solution spilled when putting in/taking out the laundry is difficult to reach the tightness of the screw 19. On the solid part, the consideration of chemical resistance can be reduced. And because the relationship between the 3rd protruding piece 16 and the opening hooking hole 17 is to withstand or approach each other, so the stress added to the 3rd protruding piece 16 is less, the washing machine body 1 and the operating part main body 3b Material selection is also easy to perform.

In addition, there is no screw between the lower end of the operation panel 3 and the washing machine body 1, so there is no need to provide decorative parts to hide the screws located around the opening 2, thereby reducing parts and reducing work steps.

To sum up, the washing machine in the utility model has a simple structure to realize an operation panel structure that is not easily affected by the drop of the product during transportation and has sufficient strength, so it can be applied to a drum-type washing machine with a heavier body, Tumble-type washer-dryer, clothes dryer, tableware washer-dryer and other occasions.
