Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electric washing machine, and particularly to an electric washing machine that is suitable for destinations that consider electrical wiring inside the machine as a source of ignition and have standards that require safety guarantees. Regarding machines.

[Background of the invention]

In recent years, many types of plastic materials have appeared, and their performance has improved significantly, and they are now often used in household electrical appliances.Electric washing machines are no exception; The inner tub, outer tub, top cover, etc. that make up a washing machine are transitioning from being made of steel plates to being made of plastic. ``However, when it comes to export products, especially export products to North America, safety against fire accidents is particularly important, and even now, steel parts are mainly used in Japan, and plastics are replacing steel. The evaluation criteria for UI and 'C8' λ standards are clearly differentiated from each other.

In other words, the C8A standard stipulates that ``all electrical equipment, including internal wiring, must be surrounded by nonflammable, moisture-resistant materials.'' Therefore, the outer frame 1 and outer tank in Figure 1 are 3. In addition to making the inner tank 5 made of steel plates, time switches and other electrical components should be covered with steel plate covers as they are considered ignition sources, or electrical components and plastic-covered parts such as internal wiring should be covered by standards. Flame retardant materials that meet or exceed standards must be used. Furthermore, the standard stipulates that, for example, if the outer tank 3 and inner tank 5 are made of general plastic materials, the standard specifies that if they were to be destroyed by fire, that is, in the state in which they were removed, The structure must be such that the specified test rod does not come into contact with any conductive parts.

In order to completely meet the above requirements, the top cover 1, outer tank 3, and inner tank 5 should be made of YK steel plate or flame retardant material that conforms to the standards, but the material cost is high and it is often used for domestic use. There is a problem that it cannot be used in common with the plastic family that is currently used.Also, there are countermeasures such as adding covers made of steel plates to completely cover electrical components and covering internal wiring with steel, but productivity is reduced. There was a problem with the price.

[Purpose of the invention]

The present invention is intended to solve all of the above-mentioned problems, and aims to provide an electric washing machine that can comply with the C8A standard regarding safety standards for electrical components, and that can be used both domestically and at low cost.

[Summary of the invention]

The present invention has been made to accomplish the above-mentioned object, and is characterized in that the electrical components and internal wiring are covered by a cover section provided by extending the outer frame of the electric washing machine. has.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In Fig. 1, the lower part of the plastic outer ellipse 3, which is supported by the outer frame 1 (made of steel plate) via the suspension rod 2 in a vibration-proof manner, is
A driving motor 4 is provided.

The outer tank 3 accommodates the inner tank 5. In addition, a water supply solenoid valve and switches 8 (not shown) are housed in a space formed by a top cover 6 that covers the upper surface of the outer frame 1 and a panel 7 (made of steel plate).

On the back side of the outer frame 1, an upper plate 9 made of steel plate and a lower plate 10 made of steel plate are attached as constituent members of the outer frame 1 with rivets or setscrews, and a drainage pump is attached to the lower plate 10. 11 is fixed using bolts or the like.

FIG. 2 is a rear perspective view of the embodiment shown in FIG. 1, in which the upper end of the lower plate 10 made of steel plate is bent integrally with the lower plate 10 at right angles toward the inside of the washing machine to form a canopy. A force bar part 12 is formed to cover the charging exposed part 13 of the drain pump 11. Also, the internal wiring 14 for the drainage pump 11 is connected to the cover part 12.
It is configured to be placed on the inner surface of the

According to this embodiment, even if it is assumed that the outer tank 3, the inner tank 5, and the top cover 6 are destroyed by fire, that is, in a state where these parts are removed, the specifications are determined from the direction of the arrow P in the figure. The covered test rod is obstructed by the cover part 12, and the internal wiring 14 does not come into contact with the charging exposed part 13.

In addition, there is no need to newly provide a cover for the charging exposed portion 13 of the drain pump 11 and a cover for the internal wiring 14 as in the prior art (the number of parts does not increase).

Furthermore, since the lower plate 10 has an L-shaped cross-section, it has greater strength and stability than a flat plate, and has a drip-proof effect even in the unlikely event of an overflow or leakage from the tank. The guide bar part 12 does not have any functional problem even if an L-shaped steel plate separate from the lower plate 10 is fixed to the lower plate 10 using rivets or the like.

Although the embodiments of the present invention have been described for single-tank electric washing machines that are in high demand for export, they can also be applied to the protection of electrical components and internal wiring in two-tank electric washing machines.

〔Effect of the invention〕

By implementing the present invention, it has become possible to provide an electric washing machine that complies with the C8A standard by covering electrical components such as a drain pump and internal wiring at low cost without providing new components.
