Description

[Detailed description of the invention] This invention relates to a dehydrating washing machine that is divided into a board on which various functional parts are arranged and a support plate that supports this board and a water tank. The support plate and the base plate are reliably positioned relative to the water tank in the preparatory work, thereby making automatic tightening reliable and easy.

An embodiment of the present invention will be described below with reference to the accompanying drawings. In Fig. 1 and Fig. 2, 1 is a main body, 2 is a washing/spin-drying tub, and 3 is provided at the center bottom. 4 is a synthetic resin water receiving tub in which the washing/spin-drying tub 2 is installed, and a lid 5 having an opening for inserting clothes is fixed to its upper edge opening. 6 is a metal base plate of approximately rectangular shape, the center of which is fixed from below to the bottom outside of the water receiving tub 4 by screws 7, and a support plate 8 of channel-like cross section with approximately L-shaped sides at both ends is fixed from below to the outer corners of the base plate 6 by screws 9, and this support plate 8 is further attached and fixed to the bottom outside of the water receiving tub 4 by screws 10 from below. The extension of this support plate 8 from the base plate 6 is elastically supported by hanging from the top of the main body 1 via vibration isolators 11 and rods 12. 13 is a power switching transmission mechanism for washing and spin-drying (hereinafter simply referred to as the mechanism),
A spin-drying shaft 14 connected and fixed to the bottom of the washing/spin-drying tub 2
The dewatering shaft 14 is provided with a rotor 3 at its end.
The washing machine is constructed so that the washing shaft 15 to which the washing machine is fixed is built in, and the two shafts 14, 15 are selectively rotated during washing and spin-drying.

16 is a screw for attaching and fixing the mechanism part 13 to the support plate 8 from below via the base plate 6, and 17 is a seal body that partitions the dewatering shaft 14 from the water receiving tank 4 in a watertight and slidable manner. Reference numeral 18 denotes a drive motor, which is attached and fixed to the substrate 6 from below via an insulating member with screws 19. The rotational force of the drive motor 18 is transmitted to the mechanism section 13 via the belt 20. 21
is a drain valve fixed to the outside of the bottom of the water tank 4 from below with a screw 22; the inlet side of this drain valve 21 is connected to communicate with a drain port 23 provided in the water tank 4; A drainage hose 24 communicating with the outside of the machine is connected to the side. Reference numeral 25 denotes a solenoid having a plunger 26 therein which operates to the suction side when energized, and is fixed to the outside of the bottom of the water receiving tank 4 with a screw 27. 8 is a continuous metal fitting having one end fixed to the plunger 26 and the other end attached to the operating body 29 of the drain valve 21, and a pin 31 that engages with the switching lever 30 of the mechanism section 13 is fixed to this connecting metal fitting 28. ing.

A pin 32 and a boss 33 protrude from the outer periphery of the bottom of the water tank 4, and guide ribs 34 protrude from the inside. On the other hand, in the support plate 8, there are holes 35 and nuts 3 fixed by caulking etc.
6 and a raised claw portion 37 for positioning. The water receiving tank 4 and the support plate 8 are provided with ribs 34 that are fitted inside the channel-shaped cross section of the support plate 8 with a small gap while positioning the outer peripheral boss portion 33 using the guide pins 32 and guide holes 35.
and fixed with screws 10. On the other hand, the support plate 8 and the substrate 6 or the mechanism part 13 are positioned by the claw part 37 and the hole 38, and the screw 19
and 16.

According to the above configuration, when fixing the support plate 8 to the water tank 4, since the guide pin 32 is located close to the boss 33 of the water tank 4, even when automatically tightening the screw 10, the tip of the screw 10 However, the boss 33 can be reliably discarded, and poor tightening caused by misalignment of the hole position can be eliminated. In addition, even if the outside of the bottom of the water tank 4 is flat on the mold, it is not a horizontal surface due to warping of the mold during molding or warping after molding shrinkage, and the outside bottom of the water tank 4 is centered at the center of the water tank. Since the rib 34 often has a convex or concave surface, the rib 34 often falls in either direction in its thickness direction. However, according to this configuration, even if the rib 34 is tilted and the position of the tip is misaligned, the tip fits inside the support plate 8 in a direction perpendicular to the longitudinal direction of the support plate 8. There is no wobbling in the transverse direction, and since the longitudinal direction is also positioned using the pin 32 as described above,
The support plate 8 can be easily fitted into the water receiving tank 4 without wobbling. Also, when fixing the support plate 8 and the water tank 4, it is good if there is a gap between the screws 10 and the support plate 8, but as the screws 10 become tighter, it is necessary to tighten them securely by tightening them at the end. In this case, the support plate 8 tends to rotate around the pin 32, and rotation prevention is required. In this configuration, when the water receiver 4, the support plate 8, and the base plate 6 are fitted together, the claw portion 37 and the hole 38 prevent rotation, and when only the water receiver 4 and the support plate 8 are fixed, Since the shape of the rib 34 is in the longitudinal direction with respect to the rotating direction of the support plate 8, its strength can be ensured and co-rotation can be suppressed.

Similarly, when fastening the screws 9 and 16, the engagement part by the claw part 37 is located in the middle of the fastening part, so the hole position can be reliably discarded, and
The above-mentioned co-rotation is prevented by the outer circumferential fastening portion of the water receiving tank 4 that has been fastened in the previous step.

As described above, according to the present invention, when fixing the support plate and the board to the water tank by automatic tightening of screws,
To provide a high-quality, rational, and highly productive dehydrating washing machine that allows each part to be easily and reliably attached in a pre-work, and does not cause positional deviation defects such as co-rotation even during automatic tightening. be able to.
