Description

Knob assembly structure of washing machine {A STRUCTURE FOR KNOB ASSEMBLY OF WASHING MACHINE}

The present invention relates to a knob assembly structure of a two-chamber washing machine, and more particularly, a knob assembly structure of a washing machine in which liquid such as water penetrated into an assembly gap between a front panel and a knob from the outside of the washing machine is not leaked by a capillary phenomenon. It is about.

Knob assembly structure of the conventional washing machine, as shown in Figures 1 and 2, the front panel 20 is coupled to one side of the upper surface of the washing machine body 10, and fixed on both sides of the lower surface of the front panel 20. Washing Timer 40 and Spinning Timer 50 coupled to each other via a plurality of fastening screws 30 at intervals, and at predetermined intervals on the upper surface of the front panel 20, respectively. It is composed of a plurality of knobs (60) coupled to the washing timer (40) and the spinning timer (50), respectively, while freely rotating.

Here, the front panel 20, a plurality of recesses 21 are formed on the upper surface at regular intervals, respectively, and in the center of the plurality of recesses 21 in the lower portion of the front panel 10 A plurality of through-holes are formed such that the shafts 41 and 51 of the washing timer 40 and the spinning timer 50 and the plurality of knobs 60 installed on the front panel 20 are correspondingly coupled to each other. 22 is formed, and ribs 23 extending vertically upward are formed at the edges of the plurality of through holes 22.

At this time, the concave portion 21 is formed in a shape in which the upper portion is opened so that the vertical portion is loosely fitted in the concave-convex shape with the vertical portion extending to the outer peripheral lower ends of the plurality of knobs 60.

Meanwhile, the shafts 41 and 51 of the washer timer 40 and the spinning timer 50 are coupled to the shaft groove 61 formed in the center of the lower surface of the plurality of knobs 60 so as not to be idle.

However, in the conventional knob assembly structure of the washing machine configured as described above, a liquid such as water penetrates into an assembly gap between the front panel 20 and the knob 60 from the outside of the washing machine, and is recessed in the recess 21. Through holes 22 formed in the center of the through-hole 22 to prevent them from flowing down to the terminals of the washing timer 40 and the spinning timer 50 to cause electrical defects (leakage), etc. The ribs 23 vertically bent at the upper edges of the edges 22 are integrally formed, but the ribs 23 have a structure such as water accumulated in the recesses 21 to form the surface of the ribs 23. There was a problem that can not prevent the capillary phenomenon to flow down the through-hole 22 to ride.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a rib in which a liquid such as water accumulated in the recess formed on the upper surface of the front panel where the knob is seated is perpendicular to the top of the edge of the through hole. It is to provide a knob assembly structure of the washing machine to block the capillary phenomenon flowing to the terminal of the riding washer timer and spinning timer.

Knob assembly structure of the washing machine according to the present invention made to achieve the above object, through the front panel with the concave through-hole is formed in the front panel so that the upper knob and the lower side washing and spinning timer penetrate to each other correspondingly In the knob assembly structure of a washing machine having a portion, the front panel is a rib protruding from the bottom of the recess with a predetermined height with respect to the edge of the through-hole, and protrudes from the bottom of the recess to a predetermined height and the outer periphery of the rib The auxiliary ribs may be configured to maintain a predetermined distance from the side to form a predetermined gap GAP.

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

For reference, the same components and the same reference numerals are assigned to the same components as the conventional components in the drawings, and detailed description thereof will be omitted.

In the knob assembly structure of the washing machine according to the present invention, the rib of the through hole 22 formed in the center of the recess 21 of the front panel 20 at a predetermined height at the bottom of the recess 21 23 is protruded and the auxiliary rib 25 at a predetermined height at the bottom of the recess 21 to form a predetermined gap (GAP) by maintaining a predetermined distance with the rib 23 around the outer circumference of the rib (23). )

At this time, only the upper part of the gap GAP is opened between the circumferences of the auxiliary ribs 25 and the ribs 23.

Further, the auxiliary ribs 25 and the ribs 23 protrude vertically from the bottom of the recess 21 at the same predetermined height.

Next, the operation and effects of the present invention configured as described above will be described.

When liquid such as water penetrates into the assembly gap between the front panel 20 and the knob 60 from the outside of the washing machine, the liquid such as water enters into the recess 21 formed in the front panel 20 as shown in FIG. Going.

At this time, the liquid such as water accumulated in the recess 21 is equally protruded from the bottom of the recess 21 at a predetermined height with respect to the edge of the through hole 22 penetrated in the center of the recess 21. The ribs 23 and the auxiliary ribs 25 formed with a predetermined gap GAP are not overflowed but stagnated, and then gradually evaporate naturally by the ambient temperature.

However, liquid such as water stagnant in the recess 21 overflows from the space in the recess 21 while flowing by the rotational operation of the knob 60 or by the vibration of the washing machine. In this case, the liquid, such as water, may be finely introduced into the gap GAP formed between the auxiliary ribs 25 and the ribs 23, but again through the ribs 23 in the gap GAP. It will not overflow.

The reason is that the gap GAP formed between the auxiliary ribs 25 and the ribs 23 can not be prevented from finely overflowing the liquid such as water in the recess 21 through the auxiliary ribs 25. In the gap GAP, the flow causing the capillary phenomenon can be interrupted while overflowing again through the ribs 23, so that a liquid such as water immediately passes through the ribs 23 and passes through the ribs 23 in the recess 21. The problem of leaking with (22) can be solved.

As described above, the knob assembly structure of the washing machine according to the present invention vertically protrudes two ribs having an upper side open at an upper edge of an edge of a through-hole formed in the center of the recess of the front panel and having a constant gap toward the circumferential side. Because of this structure, the capillary phenomenon is blocked by the two ribs of liquid such as water accumulated in the recess.
