Description

[Detailed description of the invention] The present invention relates to a dehydrating washing machine in which the support plate is divided by the base plate on which each component is attached.
The support plate is securely held on the base plate and the water tank in the pre-work of automatic tightening of screws in assembly work, making automatic tightening reliable and easy, and further improving the strength of the entire mechanism.

The present invention will be described below with reference to the accompanying drawings showing one embodiment thereof. In the figure, 1 is a main frame, 2 is a dewatering/washing tub, and a rotary blade 3 is arranged at the center bottom. 4
1 is a water receiving tank containing a tank 2, and a lid 5 is arranged on the upper edge. 6 is a substantially rectangular substrate. The center portion of this board 6 is fixed to the water receiving tank 4 from below with screws 7. An L-shaped support plate 8 extends from the outer edge corner of the board 6, and its mounting structure will be explained. The support plate 8 has a central portion located from one end thereof within a groove formed by pressing the substrate 6. The support plate 8 is approximately L-shaped in the length direction, but its cross-sectional shape is approximately U-shaped,
The flange portions on both sides correspond to the side walls of the groove. Further, an L-shaped bent portion 34 is partially provided at one end of the support plate 8, and is engaged with a square hole portion 35 provided in the substrate 6, and a central portion 36 is parallel to the water receiving tank 4. It is sandwiched and positioned between a pair of ribs 37 formed by. The support plate 8 is fixed near one end of the outer edge from below to a boss 38 formed between the ribs 37 of the water receiving tank 4 with a screw 9, and is fixed near the other end to the base plate 6 with a screw 10. Furthermore, the vicinity of the other end is fixed from below to a boss 39 formed in the water receiving tank 4 via the substrate 6 with a screw 11. Further, the support plate 8 is a vibration isolator 12.
It is suspended and supported from the upper part of the main frame by a rod 13 via. Reference numeral 14 denotes a dewatering/washing switching transmission mechanism, which includes a dehydrating shaft 15 connected to the bottom of the dehydrating/washing tub 2, and is fixed to the base plate 6 from below with screws 16. Further, the water chamber in the upper water receiving tank 4 and the lower mechanism chamber are watertightly partitioned by a seal body 17 disposed on the upper part of the mechanism section 14. Reference numeral 18 denotes a drive motor, which is fixed to the substrate 6 from below with a screw 19 and transmits power to the mechanism section 14 via a belt 20. Further, the mechanism section 14 has a washing shaft 21 installed coaxially with the dewatering shaft 15, and this washing shaft 21
The rotary blade 3 is fixed to the upper end of the washing machine, and switching between washing and dehydration is performed. 22 is a leg provided at the bottom of the main frame 1. 23 is a drain port provided at the bottom of the water receiving tank 4, and is connected to a pot 24. 25 is a valve body;
26 is an external drainage hose connected to the pot 24. The pot 24 is fixed to the water receiving tank 4 from below with screws 27. Reference numeral 28 designates a solenoid mounting plate, which is fixed to the board 6 from below with screws 29, and is fastened to the support plate 8 and the board 6 together with the screws 10. A solenoid 30 is fixed to the solenoid mounting plate 28 from below with screws 31, and is also connected to the socket 24 via a connecting fitting 32, so that when the solenoid 30 is energized, it absorbs electricity and closes the socket 24.
Pull the valve body 25 to drain the water in the water tank 4. Reference numeral 33 denotes a lever body protruding from the mechanism part 14 that is engaged with and operated by the connecting fitting 32.

The above-mentioned dehydrating washing machine, like a normal one, performs washing by rotating the rotary blade 3, and performs dehydration by rotating the dehydrating/washing tub 2. The assembly of this dehydrating washing machine is
As shown in FIG. 2, each member is assembled and fixed with each screw, with the entire device turned upside down.

As described above, according to the dehydrating washing machine of the present invention, when the support plate is fixed to the board and the water tank by automatic tightening of screws, the bent part of the support plate is engaged with the square hole part of the board in the pre-work. By positioning the middle of the support plate between the pair of ribs of the water receiving tank, the support plate will be held in the front, back, left and right, and the support plate will not shift and become unable to be tightened automatically, allowing for reliable and easy automatic tightening. It has the characteristics of being able to be tightened and improving the strength of the entire mechanism. In particular, a support plate having a substantially U-shaped cross section is positioned in a groove provided in a substrate, a bent portion is engaged with a square hole provided in the groove, and screws are used to connect the support plate to the substrate and the water receiving tank. The flange of the support plate can be brought into close contact with the inner surface of the groove, and even if complicated movements such as torsional force are applied to the support plate through the vibration isolator when the water receiving tank shakes due to vibrations, the support plate will remain intact. This prevents deformation, displacement, etc., and allows the water tank to swing stably.
