Description

[Detailed description of the invention] The present invention relates to a dehydrating washing machine that is equipped with a washing and dehydrating tank having rotary blades at the bottom inside the outer tank. This prevents soap scum adhering to the outer peripheral wall or the inner peripheral wall of the outer tank from entering the washing/dehydration tank and contaminating the laundry inside, and also ensures that soap scum is removed using a filter. It was designed so that it could be used.

The present invention will be explained below based on the drawings shown as one embodiment.

Reference numeral 1 denotes an outer tank, and inside thereof, a washing and dehydrating tank 3 having a large number of dehydrating holes 2 in the peripheral wall is provided.

At the center of the bottom of this dehydration tank 3, an opening 4 with a lower bottom is formed, and a rotary blade 5 is disposed above the opening.

An impeller 7 having radial blades 6 hanging from its lower surface is disposed below the rotary blade 5.

The impeller 7 and the rotor 5 are fixed together to the rotor shaft 8.

That is, the system part 9 of the impeller 7 is fitted into the upper part 8' of the rotor blade shaft 8, which has a non-circular cross-section, and this boss part 9 also has a non-circular cross-section. The boss portion 10 of the rotary blade 5 is fitted onto the outer periphery of the shaft 8, and the screw 11 is inserted into the shaft 8.
The impeller 7 and the rotor blade 5 are fixed to the shaft 8 by tightening from the upper end.The impeller 7 is further provided with a plurality of small holes 35 near the center thereof, and the upper and lower sides of the impeller 7 are provided with a plurality of small holes 35. It's communicating.

A cover 12 is attached to the periphery of the opening 4 with screws 13 and extends between the rotor blade 5 and the impeller 7 to the vicinity of the boss portion 10 of the rotor blade to partition the two.

A tip 14 of the cover 12 is bent upward, and an annular rib 15 is provided hanging from the back surface of the rotary blade 5 so as to surround the tip 14.

An annular rib 16 with one portion 16' open and a plurality of bosses 17 are suspended from the outer bottom surface of the dewatering tank 3.

Reference numeral 18 denotes a dehydration tank substrate that can be fixed to the drive shaft 19 of the dehydration tank 3 and forms the bottom surface of the dehydration tank.
6 and a boss 17 are in contact with each other, and a screw 20 is fastened to the boss 17 to connect the substrate 18 and the dehydration tank 3.

A pump chamber 21 is formed by the cover 12, the annular rib 16, and the base plate 18.

A plurality of through holes 22 are provided in the substrate 18, and the impeller 7
During rotation, the liquid between the outer tank 1 and the dehydration tank 3 is sucked into the pump chamber 21 through the through hole 22 by the pumping action of the blades 6 of the impeller 7 as shown by the arrow in FIG.

At the outer bottom of the dehydration tank 3, an open portion 16 of the annular rib 16 is provided.
A discharge port 23 of the pump chamber 21 is formed in communication with the pump chamber 21.

24 is a cover attached to a part of the corner of the outer bottom surface of the dehydration tank to form the discharge port 23.

A vertical groove 25 whose lower end communicates with the upper end of the discharge port 23 is formed in the inner wall of the dewatering tank 3, and a water pipe 26 made by blow molding is fitted into the vertical groove 25.

The lower end of this ice pipe 26 is connected to the upper end of the discharge port 23,
- The balance ring 27 on the edge of the dehydration tank 3 is at the end of the sumo wrestler.
It is curved downward in a recess 28 formed on the lower surface of the holder.

A filter 29 made of a mesh bag is detachably installed in the dewatering tank opposite the tip of the water pipe 26.

30 is a liquid that acts as a balancer.

Therefore, when the rotary blade 5 rotates during washing or rinsing, the impeller 7 also rotates, and the liquid between the outer tank 1 and the dehydration tank 3, which is sucked into the pump chamber 21 as described above, is transferred to the discharge port 23, The water is sent through the water pipe 26 and into the dehydration tank 3 through the filter 29 as shown by the arrow in Fig. 1, and then exits from the dehydration hole 2 again between the outer tank 1 and the dehydration tank 3, whereupon the same cycle is repeated. Due to the pump action of the impeller, the amount of liquid sent to the dehydration tank 3 through the filter 29 is made larger than the amount of liquid flowing from the inside of the dehydration tank through the dehydration hole 2 to the outside of the dehydration tank, and the water level in the dehydration tank is increased. The size and shape of the blades 6 of the impeller 7, the number and size of the dehydration holes 2, etc. are set so that (Hl) is higher than the water level (H2) between the dehydration tank and the outer tank 1.

In FIG. 1, 31 is a bearing case, and 32 is a motor, which are attached to the outer bottom surface of the outer tank 1, and the outer tank 1 is suspended from the top of a machine frame (not shown).

Incidentally, in recent years, environmental pollution caused by neutral detergents used for laundry has become a social problem, and as a result, more and more households are using powdered soap instead of neutral detergent. This adhering soap scum (rho) adheres to the outer peripheral wall of the washing and dehydration tank and the inner peripheral wall of the outer tank, and this adhering soap scum changes color and eventually peels off and floats in the liquid between the outer tank and the washing and dehydration tank, and is not used in conventional dehydration washing. In this machine, there is a problem in that the floating soap scum enters the washing/spindle tank through the numerous dehydration holes in the peripheral wall of the washing/spindle tank and contaminates the laundry inside.

However, according to the dehydrating washing machine of the present invention, the liquid between the outer tub 1 and the washing/deicing tank 3 is sent to the filter 29 attached to the upper part of the washing/dehydrating tank by the pump action of the impeller 7. The soap scum floating between the outer tank 1 and the dehydration tank 3 is also sent to the filter 29 together with the liquid, where it is captured together with the lint etc. contained in the liquid.

At this time, since the small R135 is provided near the center of the impeller 7, the liquid on the upper side of the impeller 7 is affected by the negative pressure on the lower side of the impeller, and flows into the small hole 35 as shown by the arrow Z in FIG. It receives the force that is trying to be sucked into the underside of the impeller through the impeller.

As a result, even if the liquid containing soap scum sucked into the pump chamber 21 attempts to overcome the lower side of the cover 12 to the upper side and leak from around the rotary blade 5 into the dehydration tank 3, the force 2 prevents the liquid from leaking into the dehydration tank 3. Since it is returned to the lower side of the impeller 7 through the hole 35, it will not leak out from around the rotor blade 5.
All are sent to filter 29.

The soap scum can then be reliably captured by the filter 29 without escaping into the dehydration tank.

Therefore, the laundry A in the dehydration tank is not contaminated with soap scum, and the soap scum can be reliably removed by the filter, which is an excellent effect.

If the water level (Hl) in the dehydration tank is made higher than the water level (H2) between the dehydration tank and the outer tank by the pumping action of the impeller as in the example, the water pressure in the dehydration tank will increase between the dehydration tank and the outer tank. The flow of water from the outside of the dehydration tank into the dehydration tank through the dehydration hole 2 is completely blocked, and the fear of soap scum entering from the dehydration hole 2 can be completely eliminated.
