Description

[Detailed explanation of the idea] The present invention relates to a washing machine with a drain pump.

An example of the overall configuration of a washing machine with a drain pump will be described with reference to FIG. Reference numeral 1 denotes an outer box, and inside the outer box 1, a water receiving tank 2 is suspended and supported by a support rod 3. Inside the water receiving tank 2, a washing/dehydration tank 4 is arranged rotatably around a vertical axis, and a pulsator 5 for washing is provided at the center of the bottom of the washing/dehydration tank 4. is rotatably arranged. A drain port 6 is provided at the bottom of the water receiving tank 2.
The drain port 6 is connected to a forced drain pump 9 via a drain 7 and a drain hose 8.

In a conventional washing machine with a drain pump, as shown in FIG. It was attached to flat parts c or d on both sides of the lower center part. That is, as shown in FIG.
is attached to the pump mounting plate 12 with machine screws 11 together with the pump cover 10, and this pump mounting plate 12 has a reinforcing plate 13 on the inner surface of the flat part c or d.
It was attached to the pump attachment part, which was fixed by welding, with machine screws 14. However, in such conventional washing machines equipped with a drain pump, in order to deal with deformation of the outer box 1 and other abnormalities that occur due to handling of goods during transportation, the outer box 1 is larger than a washing machine without a forced drain pump 9. The thickness of the plate had to be increased, which was uneconomical.

In view of the above-mentioned points, the present invention provides a washing machine with a drain pump that can reduce the thickness of the outer box, and one embodiment thereof will be described below with reference to the drawings.

In FIG. 4, reference numeral 1 denotes an outer box, and both ends of the outer box 1 in the circumferential direction are connected to each other by outer box joining plates 15 and 16, and both ends of the outer box joining plates 15 and 16 are It is overlap-welded to the outer case 1 at parts e and f and parts g and h. A forced drainage pump 9 is attached to the inner surface of the g section or h section as shown in FIG. That is,
The forced drainage pump 9 is attached together with a pump cover 10 to a pump mounting plate 12 with machine screws 11, and this pump mounting plate 12 has a pump mounting portion formed by fixing a reinforcing plate 13 to the inner surface of the portion g. 14
It is attached at a to 14c. More specifically, one end of the outer box joint plate 16 is recessed by the thickness of the outer box 1, as shown in FIG. One end in the direction is overlapped by a distance L and welded. In other words, the inner surface 17a of the recess 17 constitutes the inner surface A of the overlapped portion of the outer box joint plate 16 and the outer case 1, and is continuous with the inner surface A of the overlapped portion and is flush with the inner surface A. It constitutes B. Further, in the outer box 1, a recessed part 18 is formed by pressing adjacent to the overlapping part,
The inner surface C of the recessed portion 18 is flush with the inner surface A of the overlapping portion. The reinforcing plate 13 is fixed across the inner surfaces A, B, and C, which are formed flush with each other, and the machine screws 14a, 14b, and 14c pass through portions corresponding to the inner surfaces A, B, and C, respectively. are doing. Further, the forced drainage pump 9 is installed so that its center of gravity is perpendicular to the overlapping surface D of the outer case joint plate 16 and the outer case 1. In other words, the forced drainage is made such that the perpendicular line l drawn from the center of gravity G (FIG. 5) of the forced drainage pump 9 to the plane including the overlapping surface D always passes through the overlapping surface D having a predetermined area. A pump 9 is attached.

In this way, the overlapping portion of the outer case joint plate 16 and the outer case 1 is provided, and the forced drainage pump 9 is arranged such that its center of gravity G is perpendicular to the overlapping surface D of the outer case joint plate 16 and the outer case 1. Since the forced drainage pump 9 is mounted so as to be located in the direction, the attachment part of the forced drainage pump 9 to the outer case 1 is strong, and therefore, the outer case 1 which is caused by handling of cargo during transportation like a conventional washing machine with a drain pump. In order to deal with deformation and other abnormalities, there is no need to increase the thickness of the iron plate used for the outer box 1, and the outer box 1 has a thickness equivalent to that of a washing machine without a forced drainage pump 9. This makes it possible to fully guarantee quality, save resources, and be economical, as well as reduce weight.

As explained above, according to the washing machine with a drain pump according to the present invention, the thickness of the outer box can be reduced, so that it is economical and lightweight.
