JPH07144085A - Stirring vane for washing machine - Google Patents

Abstract

PURPOSE:To obtain a stirring vane which is enhanced in surface rigidity and is designed to increase a circulating water volume and waste thread capturing quantity by using a hard resin on the front surface side of the stirring vane for a washing machine and executing double molding by using a general-purpose resin for the rear surface side. CONSTITUTION:This stirring vane 1 is formed by double molding of the hard resin 2 for the front surface side and the general-purpose resin 3 for the rear surface side. For example, a propylene resin is used as the general-purpose resin 3. The surface of the hard resin 2 on the front surface side is projectingly provided with ribs 4 for stirring radially and rear vanes 6 are formed in the positions corresponding to the central positions of the ribs 4 of the general-purpose resin 3 on the rear surface side so as to be made high. The extension of the sink marks based on the formation of the tall rear vanes 6 on the general-purpose resin 3 side by the double molding in such a manner to the resin 2 on the front surface side does not arise and, therefore, the tall rear vanes 6 are formable and the circulating water volume and yarn thread capturing quantity are increased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding structure for a stirring blade of a washing machine.

[0002]

2. Description of the Related Art A conventional stirring blade of a washing machine is usually integrally formed of a general-purpose resin having good moldability such as polypropylene.

[0003]

However, in the case of the stirring blade integrally molded with the above-mentioned general-purpose resin,
There were the following problems.

First of all, since the material is soft, the buttons, fasteners, and the like of the clothing are apt to be scratched when they come into contact with the surface during operation.
Furthermore, since the whole is integrally molded, sink marks of the resin occur on the surface side corresponding to the radial back blade portion where the amount of resin increases, and the appearance becomes poor, so the back blade cannot be formed too high, As a result, it was not possible to obtain a stirring blade having a sufficiently high back blade and a large amount of circulating water and a large amount of thread waste trapped.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a stirring blade having excellent surface rigidity and capable of increasing the amount of circulating water.

[0006]

According to the present invention, the stirring blade of the washing machine is double-molded with a hard resin on the front side and a general-purpose resin on the back side.

[0007]

[Function] Since the surface side is made of hard resin, the surface is not easily scratched. Since the front side and the back side are double molded,
Even if the blades are formed high on the back surface side, the sink marks caused thereby do not extend to the front surface side.

[0008]

1 is a cutaway plan view of a stirring blade of a washing machine according to the present invention, and FIG. 2 is a sectional view thereof.

The stirring blade 1 is made of a double resin by using a hard resin 2 on the front side and a general-purpose resin 3 on the back side.
As the general-purpose resin 3, for example, polypropylene resin is used. Ribs 4 for agitation are radially provided on the surface of the hard resin 2 on the front surface side, and the back blade 6 is raised to a position corresponding to the center position of the rib 4 of the general-purpose resin 3 on the back surface side. Has been formed.

FIG. 3 shows the structure of use of the stirring blade 1 described above. The stirring blade 1 is arranged below the washing / dehydrating tank 7.

Since the stirring blade 1 is made of the resin 2 having a hard surface as described above, the surface of the stirring blade 1 is hard even if a button or a fastener of clothes is touched during operation, so that it is not scratched or worn. In addition, even when the high back blade 6 is formed on the side of the general-purpose resin 3 as described above, the sink mark based on it is hard resin 2 on the front surface side due to the double molding.
It does not extend to In this way, the back blade 6 is configured to have a high configuration, so that the agitating blade 1 having a large circulating water amount and a large lint trapping amount can be obtained.

[0012]

As described above, according to the present invention, it is possible to obtain a stirring blade which is not scratched or worn because the surface is hard even when the button or the fastener of clothes is hit. Further, even when a high back blade is formed, sink marks based on it are not formed on the surface side, so that a stirring blade having a high back blade and a large circulating water amount and a large lint trapping amount can be obtained.
