Description

Drain pump protection device of washing machine

The present invention relates to a drainage pump of a washing machine, and more particularly, the drainage pump cover covering the drainage pump fixedly installed on the lower base is coupled along the guide rail of the lower base to protect the drainage pump, as well as material cost and airborne. It relates to a drain pump protection device of the washing machine to reduce the.

Generally, a washing machine is divided into a 1-ch washing machine and a 2-chamber washing machine. A 1-ch washing machine performs washing and dehydration in one washing tank. These 1 tank and 2 tank washing machines perform washing for a predetermined time while repeating the process of water supply, washing, draining, rinsing, watering, etc., and after washing, drains the washing water completely and dehydrates it. Meanwhile, in the process of draining the wash water, when the wash water is drained to a higher position than the washing machine, a drain pump is installed, and the wash water can be smoothly drained by the drain pump. The drain pump is installed when necessary in each tank and two tanks, respectively, in the case of the one-chamber washing machine is generally installed in the rear of the lower base, and in the case of the two-chamber washing machine is installed in the lower side of the washing tank. In addition, these drainage pumps protect the drainage pump by providing a drainage pump cover to prevent damage such as damage caused by washing water falling from above.

Referring to the accompanying drawings for the conventional drainage pump protection device as an example as follows.

As shown in FIG. 1, the conventional drainage pump protection device is provided with a drainage pump cover 12 for covering and fixing the drainage pump 10, and the drainage pump cover 12 is fixed to the lower base 14 again. It becomes the structure that becomes.

One side wall of the drain pump 10 is formed with a screw fastening hole (not shown) before and after each so as to be fixed to the drain pump cover 12.

The drain pump cover 12 has a rectangular box shape in which the front and the rear are opened and the convex upper side is concentric with the screw fastening hole of the drain pump 10 so as to be fastened by a screw 16. (Not shown) are respectively formed correspondingly, and screw fastening holes (not shown) are formed at the front and rear, respectively, so that the bottom surface can be fixed to the lower base 14.

The lower base 14 is a wide plate shape that is covered on the bottom of the washing machine, the upper surface is formed in a position corresponding to the screw through hole (not shown) to match the screw fastening hole of the drain pump cover 12 It is.

The prior art of such a configuration firstly assembles the drain pump 10 to the drain pump cover 12. At this time, the screw fastening hole of the drain pump 10 and the screw through hole of the drain pump cover 12 are matched and fastened to the outside of the drain pump cover 12 using the screw 16. Then, the drain pump cover 12 in which the drain pump 10 is fixed is fixed to the lower base 14. In this case, too, the screw fastening holes of the drain pump cover 12 are made to coincide with the screw through holes of the lower base 14, respectively, and then fastened and fixed at the bottom surface of the lower base using the screw 16. In this way, the installation of the drain pump 10 is completed and can be safely protected from the washing water falling from the upper washing tank.

However, since the drain pump protection device as described above must first assemble the drain pump 10 to the drain pump cover 12 and then reassemble the secondary base 14 to the lower base 14, work efficiency is excessive and work efficiency is increased. As the drainage pump 10 is fixed to the drainage pump cover 12, the drainage pump cover 12 must have a strength enough to support the weight of the drainage pump 10, and thus, drainage The thickness of the pump cover 12 has a problem such that the manufacturing cost increases due to the increase in the material cost accordingly.

The present invention was devised to solve the above problems, and the work efficiency is improved by reducing the number of installation work of the drainage pump, and the drainage pump cover is fixedly installed on the lower base, so that the production of the drainage pump cover is simplified and thus the manufacturing cost. The purpose of the present invention is to provide a drainage pump protection device for a washing machine, which can be used to reduce the amount of oil.

The present invention for achieving the above object is a guide rail is formed on both sides of the upper end of the lower base is installed the drain pump, guides are formed on both ends to be guided along the guide rail to cover the drain pump It features a drain pump protection device of the washing machine equipped with a drain pump cover bulging in the center.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 to 3, the drainage pump protection device of the present invention has a configuration in which the drainage pump 20 is fixedly installed on the lower base 24 and the drainage pump cover 22 covering the drainage pump 20 is provided. It is.

The screw fastening hole 20a is formed in the front and the rear of the drain pump 20 so as to be fixed to the lower base 24.

The lower base 24 has a screw through hole 24a corresponding to the screw fastening hole 20a of the drain pump 20 correspondingly formed therein, and guide rails to guide the drain pump cover 22 on both sides of the upper base. 26 are formed to face each other.

The drain pump cover 22 has a semi-circular tube shape of which front, rear and bottom are opened, and guide parts 22a are extended to both sides so as to be guided along the guide rails 26 of the lower base 24 at both ends. have.

The subject innovation of this configuration is to first install the drain pump 20 to the lower base (24). At this time, the screw fastening hole 20a of the drain pump 20 and the screw through hole 24a of the lower base 24 coincide with each other, and then the drain pump (at the bottom of the lower base 24 using the screw 28) 20) Tighten and fix. Then, the drain pump cover 22 is covered with the drain pump 20 above. At this time, the guide portion 22a of the drain pump cover 22 is guided along the guide rail 26 of the lower base 24 to cover the drain pump 20. The drain pump cover 22 covered by the guide rails 26 is thus easily attached and detached. Hanpun the drain pump cover 22 is made of a material such as PVC or PE (PE) to facilitate the production.

As described above, the drainage pump protection device of the washing machine according to the present invention has conventionally installed the drainage pump cover on the drainage pump cover, and then mounted the drainage pump cover on the lower base. Since the pump cover is installed in the pump cover, the manufacturing cost is increased due to the increase in the material cost to reinforce the strength of the drain pump cover. However, the drain pump is installed directly on the lower base and a separate drain pump cover is located above. By reducing the workmanship, the work efficiency is reduced, and the production of drainage pump cover is easy, and the material cost is reduced, and at the same time, the manufacturing cost can be reduced.
