Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a washing machine equipped with a water tank for reusing detergent liquid and rinse water.

(b) Prior Art Recently, washing machines equipped with a water tank that can reuse detergent solution and rinse water have been widely used from the viewpoint of energy conservation. This water tank is generally made of a plastic molded product, and because it has a narrow structure so as not to increase the overall width of the washing machine too much when installed, it inevitably swells in the width direction when it is full of water. This was unsightly and also caused cracks in the water tank after long-term use. It is known to reinforce the tank wall with an uneven structure, but this method has the problem of poor appearance, easy accumulation of dirt, and time-consuming removal when dirt accumulates.

(c) Purpose of the invention This invention was created in view of the above circumstances.
To provide a reinforcing structure for a water tank of a washing machine with a water tank that looks good and is easy to prevent stains.

(d) Structure of the device In this device, the side wall of the water tank is reinforced by providing a reinforcing ridge on the upper part of its outer surface. This is a washing machine with a water tank, in which a water tank is attached to the side, and the washing tank and the water tank are connected by a water pipe. This washing machine with a water storage tank is characterized in that a reinforcing ridge is integrally provided to continuously project outward and reinforce the water storage tank.

(e) Examples Examples of this invention will be described below in detail with reference to the drawings, but this invention is not limited to the following examples.

FIG. 1 shows the overall configuration. Reference numeral 1 denotes a machine frame, and a water tank 2 is provided horizontally on one side of the machine frame 1. The machine frame 1 is equipped with an inner tank for dewatering and a washing tub 3 equipped with a pulsator, and this washing machine is of a fully automatic type. The washing tub 3 is appropriately equipped with piping for water distribution, and the washing tub 3 and the water storage tank 2 are connected by a water pipe 4 at the bottom thereof. Although not shown, the water pipe 4 is equipped with a reversible pump, which is configured to move detergent liquid and rinse water from the washing tub 3 to the water storage tank 2 and vice versa. ing. The detergent solution and rinse water in the washing tub 3 are temporarily stored in the water storage tank 2 and reused.

Reference numeral 5 denotes a top plate which is attached to integrally cover the machine frame 1 and the water tank 2, and lids 6 and 7 are attached to positions facing the opening of the washing tub 3 and the opening of the water tank 2, respectively. be done. A box-shaped base 8 is provided integrally with the machine frame 1 so as to support the water tank 2, and legs 9 are provided on the lower surface.

The water tank 2, like the base 8, is made of a molded product of plastic such as polypropylene.

FIG. 2 shows a cross-sectional configuration of the portion shown in FIG. 1, and the washing tub 3 portion is not shown. A side wall 10 of the water tank 2 located far from the machine frame 1 is configured to curve outward so as to reinforce the water tank 2 and make it less noticeable even if it swells.

Furthermore, in the water storage tank 2, as shown in FIG.
A reinforcing ridge 11 is integrally provided that continuously projects outward in the front and back to reinforce the water tank 2. However, the reinforcing flange 11 does not reach the rear part of the side wall 10. As shown in FIGS. 4A and 4B, this reinforcing flange 11 has an inverted L-shaped cross section, and a reinforcing rib 12 is provided in the middle. A boss 13 for fixing the top plate 5 is integrally provided on the reinforcing flange 11 in the horizontal direction. A total of three fixing bosses 13 are provided in a space 14 partitioned by the reinforcing ribs 12, and a screw hole 16 is provided on the outer surface 15 of the reinforcing ridge 11 facing the bosses 13. At the position where the fixing boss 13 is provided, the bottom portion 17 of the reinforcing flange 11 is located slightly higher than the other bottom portions 17.
Reference numeral 18 denotes a drain hole, through which the water accumulated in the space 14 falls downward.

The part of the hanging edge 19 of the top plate 5 that faces the reinforcing flange 11 is a protruding hanging edge 20, and when the top plate 5 is attached to the machine frame 1 and the water tank 2, the protruding hanging edge 20 is The reinforcing flange 11 is covered.
Then, screws 21 are screwed into the projecting hanging edge 20 from the outside to fix the top plate 5. The top plate 5 is of course fixed to the machine frame 1 at the other hanging edge 19 with screws. The reinforcing ridge 11 portion is also used as a handle when carrying the washing machine, and has a structure in which the bottom portion 17 slopes downward as it goes slightly outward so that it can be easily touched by fingers from below.

FIG. 5 shows another embodiment of the reinforcing flange. In this case, the reinforcing flange 11 has a simple horizontal edge shape, and a fixing boss 13 is integrally provided on its upper surface.

In FIG. 2, reference numerals 22, 22 are the legs of the dryer mounting frame used when the washing machine is used together with the dryer, and the leg 22 on one side is just behind the side wall 10 of the water tank 2. Reinforced edge 1 near the end
It is located corresponding to the part where 1 does not exist. That is, since the reinforcing flange 11 does not reach the rear part of the side wall 10, the distance between the legs 22, 22 can be reduced, and the overall space for installing the washing machine can be reduced. In reality, the dryer mounting frame is often installed upright within the washing machine pan, which makes it possible to use a smaller washing machine pan.
Note that this effect is further enhanced when the water tank has a structure in which the side wall is curved, as in the above embodiment.

(f) Effects of the invention This invention is structured as described above, so
With a simple configuration, the water tank is reinforced, looks good, and there is no need to worry about the water tank getting dirty. Further, as shown in the embodiment, the reinforcing flange has the additional effect of being usable as a handle.
