Description

[Detailed description of the invention] The present invention relates to an improvement of the lint collecting filter device installed in the center of the pulsator. It is an object of the present invention to provide a device that does not require space, allows easy attachment and detachment of a pulsator, reduces the escape of collected lint, and facilitates removal of collected lint.

In the present invention, a recess for inserting a filter is formed in the center of the pulsator, a pulsator boss is formed in the center of the recess rising from the bottom of the recess, and the bottom of the recess is provided with many grooves for water passage. A bottomed cylindrical filter for collecting lint is formed of a support bone and numerous net-like members, and a relief hole is formed in the center of the bottom part of the filter to fit into the outer periphery of the pulsator boss part. A tightening screw insertion hole is formed in the center of the pulsator boss, and the pulsator is attached to the pulsator spindle that protrudes from the inner bottom of the washing tank.The tightening screw is inserted into the tightening screw insertion hole, and the same screw is inserted. Tighten the pulsator to the pulsator support shaft, removably fit the filter into the pulsator insertion recess of the pulsator so that the pulsator boss fits into the escape hole of the filter, and removably attach the lid covering the recess to the pulsator. It's in the washing machine.

An embodiment of the present invention will be described below based on the drawings.

1 and 2, a cylindrical filter insertion recess 2 is provided in the center of the pulsator 1 of the washing machine.
is formed. A plurality of penetrating grooves 3 are provided in the bottom plate and side walls of this recess. Further, the upper end surface of the recess 2 is provided with a recess 4 that is one step more recessed than the upper end surface of the pulsator 1.

In FIG. 3, a filter 5 contained within the recess 2 and a lid 6 covering the recess 2 are shown. The bottom and side surfaces of the filter 5 are composed of numerous holes or countless net-like gaps. Further, the bottom of the filter 5 is provided with an escape hole 8 for the pulsator boss 7 to be inserted into the recess of the pulsator 1. The filter 5 has a bottomed cylindrical shape and includes a plurality of support bones 5' and numerous mesh members 5''.

Further, a large number of holes 9 are provided on the surface of the lid 6 that covers the recessed portion.

In actual use, as shown in FIG. 4, a bearing 11 that also serves as a water seal is provided at the bottom of the washing tank 10, and a pulsator 1 is mounted on a pulsator support shaft 11' that is rotatably supported by this bearing 11. will be installed. The pulsator 1 is mounted by inserting a tightening screw 7'' into a tightening screw insertion hole 7' formed in the center of the pulsator boss 7, and screwing the tightening screw 7'' onto the pulsator support shaft 11''. The filter 5 is removably installed in the recess 2 at the center of the pulsator 1, and a lid 6 covering the recess 2 is also removably installed.

When actually washing or rinsing, as the pulsator rotates, the water flow in the washing tank 10 is sucked into the center of the pulsator 1 and then discharged from the outer cylinder of the pulsator 1, which is a so-called circulating water flow. Become. Therefore, if the filter 5 is installed in the center of the pulsator 1 as described above, the water flow will be sucked in through the hole 9 of the lid 6 as shown by the arrow in FIG. A flow path is formed that penetrates through and drains water from the gap 12 between the pulsator 1 and the washing tank 10 through the groove 3 of the recess 2. However, since the lint separated from the object to be washed or rinsed flows together with the water flow, it enters through the hole 9 of the lid 6.
It will be filtered through the fine mesh of filter 5. When lint accumulates inside the filter 5,
If the lid 6 is removed, the filter 5 is taken out, and the lint inside the filter 5 is cleaned, the lint collecting ability is restored, making it easy to clean and maintain.

Furthermore, by making the hue of the lid 6 or filter 5 that constitutes the lint collecting mechanism different from the hue of the pulsator 1, the lint collecting part can be made to stand out, which contributes to improving the product value. I can do it.

As described above, the present invention forms a recess for inserting a filter in the center of the pulsator, a pulsator boss rising from the bottom of the recess at the center of the recess, and a pulsator boss at the bottom of the recess for water flow. A cylindrical lint collecting filter with a bottom is formed by providing a large number of grooves, a plurality of support bones, and countless net-like members, and a recess that is fitted into the outer periphery of the pulsator boss is provided at the center of the bottom of the filter. A hole is formed, an insertion hole for a tightening screw is formed in the center of the pulsator boss portion, and the pulsator is attached to the pulsator support shaft protruding from the inner bottom of the washing tank, and the tightening screw is inserted into the insertion hole for the tightening screw. Then, tighten the pulsator to the pulsator support shaft using the same screws, then removably fit the filter into the filter insertion recess of the pulsator so that the pulsator boss fits into the escape hole of the filter, and then insert the lid covering the recess into the pulsator. This is a washing machine that is detachably attached to the machine.

According to this configuration, the following advantages can be expected.

(1) The pulsator boss is formed to rise from the bottom of the recess for filter insertion.
Compared to those in which the pulsator boss is formed to protrude long downward from the bottom of the pulsator,
The overall length of the pulsator can be made shorter.

(2) Furthermore, if the pulsator boss is formed to protrude downward from the bottom of the pulsator, the bottom of the washing tank must bulge downward to accommodate the pulsator boss, which takes up wasted space. As a result, the depth of the washing tub becomes shallow, resulting in a reduced capacity, or conversely, the overall height of the washing machine becomes higher in order to ensure the depth. Furthermore, this space creates a space on the back side of the blade, and a complicated turbulent flow occurs within this space, which deteriorates the lint collection performance. Furthermore, there is also the problem that foreign matter tends to accumulate in this area. By removing the recessed pulsator boss for filter insertion, such wasted space can be eliminated.

(3) When the lid is removed from the pulsator, the head of the tightening screw is exposed, so the tightening screw can be turned using a screwdriver while the filter remains attached to the recess of the pulsator.

Since the pulsator can be attached and detached with the filter still attached, it is easier to attach and detach the pulsator.

(4) If lint, etc. gets entangled in the pulsator spindle through the mesh of the filter, remove the filter separately. In such a case, the filter can be easily removed by removing the entire pulsator before removing the filter.

(5) Since the filter is a cylindrical piece with a bottom made of support bones and a net-like member, it itself has shape-retaining properties. When the pulsator is switched between forward and reverse directions or when water is supplied, the filter does not become fluffy due to the backflow that flows from the outside to the inside of the filter, so the lint collected by the filter can easily escape.

(6) Since the filter itself has shape-retaining properties, the collected lint inside the filter can be easily removed by turning the filter upside down and tapping it lightly after removing it from the pulsator, or by turning it upside down and pouring water on it. This is possible.
