Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a top cover structure of a washing machine, and in particular, the top cover structure is installed below a control panel at the top of an outer frame, and has a water inlet opening and an insertion opening for piping for controlling a drive mechanism. The present invention relates to a top cover structure for a washing machine having a flat surface portion formed therein.

In a conventional dehydrating washing machine, for example, as shown in FIG. A wash basin 7 which also has a dehydrating function is rotatably mounted inside.

A motor 8 is attached to the bottom of the outer tank inside the machine, and a V-belt 9
The turbulent force is transmitted to the clutch 11 via the pulley 10, and the clutch 11 selectively switches this driving force to the washing tank 7 and the balsator 12 provided at the bottom thereof during washing, draining, and dewatering. It is designed to be communicated using In the figure, 7A is a balance ring that suppresses the vibration of the washing bowl 7 during dehydration, and 13 is a rice bowl cover that prevents water from scattering from the outer tank 5. A top cover 14 is provided on the upper part of the outer frame 1 of the washing machine.

At its rear (on the right side in Figure 1) is a panel section 1 made of IQ salmon board on which electrical components such as a timer 15 for controlling the drive mechanism such as the motor 8 and a pressure switch (not shown) are attached.
6 is provided below the panel section 16.
7 is installed. This flat plate 17 has an electrical wiring harness (
(not shown) and an insertion row 8 through which piping such as a water pipe 19 is connected to a pressure switch to detect a predetermined liquid level in the washing tank 7, and a water inlet 20 for injecting water into the washing tank 7. A barrier is formed for this purpose. However, when water is sprinkled on the panel 16 in such a top cover structure, since the flat plate 17 is installed almost horizontally, the water accumulates on the plate, and the pipes and wiring are leaked through the control piping insertion opening 18. and enter the cabin of the aircraft.

Such moisture also enters the motor 8 and clutch 11, reducing the electrical insulation of the motor or causing rust on the clutch, thereby significantly impairing the reliability and safety of these drive parts. The purpose of the present invention is to provide a top cover structure for a washing machine that can eliminate the drawbacks of the prior art and reliably prevent water from entering the machine from the entrance in the flat part below the control panel. be.

The present invention relates to a washing machine which is equipped with a flat part attached below a control panel part provided on the upper part of the outer frame of the washing machine and formed with a water inlet opening and an insertion opening for piping for controlling the drive mechanism. In the top cover structure, a facing surface is formed on the upper surface of the flat part to descend from the piping insertion port to the inlet entrance, and protrudes upwardly surrounding the outer edge of the piping port. Embodiments of the present invention will be described in detail below with reference to the drawings. Fig. 2 shows a dehydrating washing machine equipped with a top cover structure according to the present invention; , each part of the washing machine is basically the same as the conventional washing machine shown in Figure 1,
Corresponding parts are designated by the same reference numerals as in FIG.

That is, an outer tub 4 is elastically supported from a corner plate 2 of an outer frame 1 via a hanging rod 3, and a washing tub 7 is rotatably provided therein. A top cover 14 is provided on the upper part of the outer frame 1, and a control panel 22 having a decorative plate 21 is attached to the upper right side of the top cover 14 in the figure. The decorative board 21 is provided with a timer 5, a pressure switch, etc., and a wire harness 23 from these is led out to a driving machine below the washing machine. In this embodiment, a flat part 24 is also attached below the control panel 22, and an opening 26 for a water inlet is formed on the side of the water inlet 25 in this flat part 24. Wire harness 2
An insertion port 21 is formed for leading out the 3 into the agitation mechanism.

The top surface of the plan view 2& is formed as an inclined surface that descends from the insertion port 27 to the water inlet closing portion 261, and the upper twill portion of the insertion port 27 is surrounded by ribs 2 that protrude upward. There is. As shown in detail in FIG.
The upper surface of the water inlet 4 is formed into a slope 24A such that the difference in height between the Sekiguchi part of the water inlet 2 and the Hashidori 027 is L. Further, as shown in FIGS. 4 and 5, each insertion port 27 of this forehead slope base 4A intersects with the rightward extension line from the water inlet entrance section 2 light (in FIG. 3). A downward slope is also formed along the direction. In particular, this forehead slope is set to such a degree that the height difference between the extension line and each gutter opening 21 is 2, as shown in FIG. Further, the upper ridge portion of each insertion slot 27 is surrounded by a lip 28 that projects upward from the upper surface of the flat portion 24.

Therefore, even when water is sprinkled on the control panel 22, the water that falls on the flat part 24 concentrates on the Sekiguchi group 26 of the inlet 25 along the slope of the slope 24A as shown by the arrow in FIG. Since it flows down into the washing tank 7, it does not flow into the insertion port 27 of the wire harness 23.

Furthermore, the ribs 28 provided on the edge of the insertion port 27 further reliably prevent water from flowing into the machine. As described above, in this embodiment, the control panel 22 is located in the top cover structure.
A cheek slope is formed on the upper surface of the flat part 24 provided below, which descends from the insertion port 27 for the wire harness 23 etc. to the water inlet entrance part 26. All of the fallen water flows down from the water inlet entrance 26 into the washing tank 7 and does not flow into the insertion port 27, thus preventing water from entering drive mechanisms such as the sprinkler motor and clutch.

Furthermore, since a rib 28 is provided upright around the insertion hole 27, this effect of preventing inflow is even more reliable, and the deterioration of the electrical insulation of the motor and the occurrence of rust on the clutch are properly prevented. Safety and reliability can be ensured.In addition, the top cover structure of the washing machine usually incorporates a water inlet for injecting water into the washing tank as described above. By using this configuration, manufacturing and assembly of such a water inlet becomes extremely easy.

For example, as shown in Figure 6, a conventional water inlet is made up of two parts: a box-shaped member and a flap member with a large number of water inlet holes 30. After the pig joint part 3 is joined by the breasts and the entire surface of the combination is glued, it is attached to the top cover by an appropriate means.However, for this purpose, two parts are required to form the water inlet. ``Troublesome manufacturing work such as fastening required tying work. According to the top cover structure of the present invention, a water inlet can be easily formed with a small number of parts.

FIG. 7 and the fin diagram show the diamond part of the top cover structure used to form such a water inlet. As shown in FIGS. 7 and 8, a part of the top cover 32 made of a flexible synthetic resin, such as polypropylene, forms a lid for the open opening of the water injection case 33, leaving a closing part 34. A protrusion piece 35 is bent so as to be formed on the water injection case 33.
It has a groove that engages with.

Furthermore, as shown in FIG. 8, a side plate 36 formed integrally with the top cover 32 is provided with a recess 38 that engages with an engagement claw 37 formed on the water injection case 33. In Figure 8, . The formation claw 37 of the water injection case 33 is connected to the water injection case 3.
The competition guide surface 39 that mirrors smoothly tilts along the competition direction (direction of arrow P) to the top cover of No. 3 and this iron joint guide surface 39
It has a compression rear surface 40 that is adjacent to the damaged portion and abuts against the competing side wall of the recess 38 of the side plate 36. In addition, in the figure, 41 is a rectifying plate provided in the water injection case 33. In the structure of this embodiment, when the water injection case 33 is pressed toward the top cover 32 along the direction of arrow P in FIG. Due to the elastic deformation of the saddle mating guide surface 39, it is fixed in the recess 38.

On the other hand, the protrusion piece 35 also engages with the groove of the top cover 32 at the same time, and the assembly and installation of the water inlet is completed with the above operations. During water injection, a rotational force is exerted on the water injection case 33 by water pressure, but the water injection port is firmly held because the pressure acid surface 40 of the formation claw 37 is pressed against the side wall of the side plate recess 38. As described above, in this embodiment, the recess S8 is provided in a part of the top cover 32, and this is made to compete with the iron fitting claw 37 of the water injection case 33 to form the water injection port. The number of points can be reduced and the assembly work can be simplified.

In this embodiment, the iron fitting projection 43 is provided on the water injection case side and the recess is provided on the top cover side, but the iron fitting projection 43 may be formed on the side plate 42 side of the top cover as shown in FIG. In the figure, a competitive guide surface 44 is formed on the iron fitting protrusion 43 on the side where the water injection case 33 is guided by the iron fitting protrusion during assembly, and is inclined in the direction of arrow P, and on the opposite side after assembly. A pressing surface 45 is formed to engage with the back surface (right side in the figure) of the water injection case 33. In the embodiment of FIG. 9, the assembly method and the effects obtained are substantially the same as those of the embodiments shown in FIGS. 7 and 8. As described above, according to the top cover structure of the washing machine of the present invention, it is possible to appropriately prevent water from flowing into the machine from the flat surface below the control panel, thereby ensuring the reliability and safety of the drive mechanism section. I can do it.
