Abstract

PURPOSE:To improve the efficiency of carriage and disposal working by forming a thin-wall slit by press working at proper parts of a frame lengthwise to bend the frame freely on the slit, thereby facilitating the folding operation of the frame at disposal with the volume of the frame O-1/4. CONSTITUTION:Thin-wall slits 5, 6 are formed by press working at proper parts of the inside of a frame lengthwise. To fold the frame, a top plate, spin basket and back cover, etc., are removed at first, then upper and lower reinforcing crosspieces. A left side face plate 1a is bent on the 1st slit 5 like Fig. 5b. Then, a front face plate 1b is bent on the 2nd slit 6 provided on a front face plate 1b together with a right side face plate 1e like Fig. 5c, resulting in volume of the frame O-1/4.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a steel plate frame structure for electric appliances such as electric washing machines, microwave ovens, and gas oven ovens.

(b) Conventional technology In general, the frame surface is either plain without any processing, as shown in Figure 3 of Publication of Utility Model Publication No. 1-28794, or has been subjected to a push-button process to increase strength. in a state.

(c) Problems to be solved by the invention In recent years, when large home appliances such as microwave ovens and washing machines are disposed of, sometimes they cannot be put into the press at a garbage disposal plant, or because of the capacity of the garbage disposal truck. It is desired that the waste be broken down into smaller pieces and disposed of. Additionally, there is a movement to collect and dispose of products at the manufacturer's responsibility, and even in this case, it is easier to collect products if they can be broken down into smaller pieces.

However, in the prior art, it is not possible to easily disassemble and reduce the size, making it extremely difficult to collect and dispose of it.

(d) Means for Solving the Problems The present invention forms a thin groove at a suitable location of the frame from one end edge to the other edge by press working, and allows the frame to be bent freely from this groove. .

(E) Function: With the parts constituting this product removed from the inside of the frame, the frame can be folded into a small size by bending the thin small groove parts.

(F) Embodiment As an embodiment of the present invention, a frame structure of a fully automatic washing machine will be described.

Figure 1 is a completed view of the rectangular frame 1 with the top plate, dehydration tank, rear cover, and electrical components removed, and the steel strip is bent and the ends of the left and right rear plates 1d and 1e are not joined. Then, reinforcing bars 2 are screwed to the upper and lower ends of the left and right rear panels 1d and 1e.

At the four corners of the upper end of the frame 1, a plate 3 is fixed by spot welding to the suspension 9 rod supports for suspending the dehydration tank, and the plate 3 is attached to the frame together with corner plates 4 spot welded to the four corners of the lower end of the frame 1. It also serves as a reinforcement. The rear support plate 3 is integrally formed with the upper reinforcing beam 2.

The present invention has a thin small groove 5 formed by press working in a suitable place on the inner surface of the frame from one edge (upper edge) to the other edge (lower edge).
．． 6.

The first small groove 5 is provided in the left side plate 1a and in a part removed from the left front corner, and the second small groove 6 is provided in the left side plate 1a.
And it is located 1i away from a part of the front right corner.

The small grooves 5.6 can take various forms as shown in FIG.

Next, we will explain how to fold the frame.

First, remove the top plate, dehydration tank, rear cover, etc., and also remove the upper and lower reinforcing bars 2. (See FIG. 2) In this state, the left side plate 1a is bent from the first small groove 5 portion to the state shown in FIG. 5. Next, as shown in FIG. 5, by bending the front plate 1b along with the right side plate 1e from the second small groove 6 provided in the front plate 1b, the volume can be reduced to 0% to 0%. The positional relationship between the first and second small grooves will be explained based on FIG. 4. The distance ED of the first small groove 5 is larger than the length J of the side of the plate 3, and It is located shorter than center C.

Moreover, the position F of the second small groove 6 is DB<EF and BA<FG.
is determined to satisfy the relationship.

Furthermore, if a small groove line appears on the outer surface of the frame, a dummy line may be provided due to design consideration.

Also, although collar pieces 7 are provided on the upper and lower edges of the frame 1, their width is narrow so that they do not interfere with bending from the small grooves 5.6.

(g) Effects of the invention The frame can be easily bent when discarded. Furthermore, since the volume of the frame can be reduced to 0% to 10%, transportation work and disposal work are improved.
