SK5825Y1 - A tank with balancind the body - Google Patents

Abstract

A tank with balancing body to silence unacceptable mechanical vibration washing mashines and centrifugs comprises at least one material similar molded tank material and balancing the body (1) pressed into the tank (2) or its components, forming one whole.

Description

Technical field

The technical solution relates to a tank with a balancing body without the use of fasteners, or a separate operation in the tank assembly process of, for example, a drum of washing machines, dryers or centrifuges, in the household appliance industry.

BACKGROUND OF THE INVENTION

In the manufacture of automatic washing machines and spinners, balancing bodies are used to compensate for the laundry imbalance in the rotating drum of the washing machine or dryer or centrifuge, which ensures the stability of the washing machine or spinner during the washing or drying cycle, especially during spinning. These balancing bodies manufactured in different ways are primarily fixed to the tank by means of fasteners as a separate operation in the assembly of washing machines, dryers and other spinning devices. The methods currently used for fixing the balancing bodies in the washing unit are essentially based on the typology of the material used in their manufacture.

The concrete weights are fixed to the tank by means of fasteners such as screws, expansion wedges, washers and others in a separate operation during the assembly process of the washing machine on the production belts of the white goods manufacturers. For example, the solution of US5765404 is an automatic washing machine balancing ring used by Whirpool.

According to patent KR100182732 entitled Dynamic washing machine balancing device, a liquid or spheres in a liquid is used as a medium, therefore, it is not necessary to use fasteners in production, but a vertical torque is required and the balancing medium is placed in a larger package placed washing machine drum.

CN1521317 discloses a balancing block mechanism for drum washing machines that is installed on the front of the water tank of a conventional drum washing machine or a drying machine. The balancing block mechanism comprises one balancing block with a front portion suitable for attachment to a dryer duct and a second block thinner than the first and symmetrical to the first, and a third block is fixed to the end of the first.

The essence of the technical solution

Disadvantages of the prior art are eliminated by the proposed solution of the tank with the balancing body, the essence of the technical solution is that it consists of simultaneously injected and pressed balancing body in the tank or its part, if the tank consists of several parts, the balancing body with tank create monolithic whole. Part of the solution is also the division of the balancing body into several smaller segments.

The advantage of the technical solution of the tank with balancing body is the elimination of the operation of mounting the balancing bodies on the tank or parts of the tank, for example automatic washing machines, saving of fasteners that are necessary for mounting the balancing bodies on the tank or parts of the tank, for example automatic washing machines. A further advantage of the technical solution is that the balancing body injection method eliminates the problem of weights which, during the rotation of the drum tank and subsequent vibrations, are a critical point in terms of strength.

By dividing the balancing body into several small segments (for example 4) according to the invention, it is possible to better distribute them on the tank surface individually and in this way better eliminate the imbalance that occurs when the drum tank of the washing machine or other rotating device is rotated. The division of the balancing body into several independent segments is very important from the point of view of the tank production process or tank components. By dividing the balancing body into a plurality of independent segments with subsequent spraying of a material similar to a tank material, for example plastic, the need for strength of the individual segments of the balancing body is reduced, since centrifugal forces are rotated by the centrifugal forces.

Overview of the figures in the drawing

The technical solution is explained in more detail by means of the drawing, where in FIG. 1 and 2 is a diagram of a balancing body tank; FIG. 3 shows a detail of the tank with balancing body.

Example of technical solution

The tank with balancing body of FIG. 1, 2 and 3 consists of a balancing body 1, which is wrapped, for example, with plastic and is part of the tank 2 as a squeeze. The segment of the balancing body 1 is injection molded, for example, with plastic, and together with the tank 2 form a compact unit which does not require any further operation in terms of attachment of the balancing body. The balancing body tank according to the invention consists of at least one co-injection and balancing body X in the tank 2 or a part thereof, forming a monolithic unit and a preferred solution is to divide the segments of the balancing body X into several small segments according to FIG. First

Claims (2)

PROTECTION REQUIREMENTS Tank with a balancing body for damping unwanted mechanical oscillations of washing machines and centrifuges, characterized in that it consists of at least one co-injection material similar to the material of the tank and the molded balancing body (1) in the tank (2) or its component, forming a monolithic whole . The balancer body tank according to claim 1, characterized in that it comprises at least two segments of the balancer body (1) in the tank (2) or a part thereof.
