Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a single-tub type dehydrating washing machine used in general households.

Conventional structure and its problems Traditionally, in countries such as the United States, Canada, Australia, and New Zealand, their domestic safety standards require that washing machines include a time switch 1, an electromagnetic water supply valve 2, and a water level detection switch (not shown). If the water supply control system fails and the water supply to the washing machine cannot be stopped, water overflowing from the water tank 3 must not splash onto any electrical components (e.g. motor 4, drain pump 5). We have established regulations. ) Therefore, in order to prevent the water supplied to the washing machine from overflowing from the top of the water tank and scattering on the floor even if the water supply control system breaks down,
As shown in Figure 1, in order to deal with the occurrence of the aforementioned abnormality, a dedicated overflow port 6 was provided, and an overflow hose 7 was installed from this overflow port to the floor so that the overflowing water would not wet electrical components. .

However, in recent years, in order to improve the corrosion resistance of the water tank 3 and the washing and dehydrating tank 8 and to reduce material costs, there has been a trend to mold them from synthetic resins. . Synthetic resin molded products require a slope for releasing the mold during molding.
For this reason, in a single-tank dehydrating washing machine in which the water tank 3 and the washing and dehydrating tank 8 are made of synthetic resin, the rotation of the washing and dehydrating tank 8 (in the direction of arrow A) during the dewatering process is limited, as shown in Fig. 2 A and B. The water that has been dehydrated from the laundry is collected through a small hole 8 provided on the side wall of the laundry dehydration tank 8.
From a, the water is discharged to the water tank 3 side, and this discharged water flows upward along the slope of the wall of the washing/dehydration tank 8 and the wall of the water tank 3, as shown by the arrow. Therefore, simply arranging the overflow port integrally with the water tank 3 on its outer periphery to deal with the occurrence of the above-mentioned abnormality would cause overflow even during normal use, resulting in a problem. Therefore, by fitting the overflow port connector 9 as shown in FIG. The structure was designed to prevent this from happening. As shown in FIGS. 3 and 4, the overflow port connection portion 9 includes a fitting portion 9a for fitting into the overflow port 6 of the water tank 3, a flange portion 9b that clamps the overflow port inner wall 6a, and a substantially cylindrical overflow port 9c. have.

When inserting this overflow port connector 9, the overflow port connector 9
An adhesive is applied to the fitting part 9a to the overflow port 6 to hold the fitting part watertightly.

In such a conventional overflow port connection part 9, the adhesive applied to the fitting part 9a of the water receiving tank 3 to the overflow port 6 adheres to the wall surface of the water tank when it is inserted, and most of the applied amount is It was not easy to maintain the overflow port 6 of the aquarium and the overflow port connector 9 inserted therein in a watertight manner.

Purpose of the invention The present invention solves these conventional problems and provides a single-tank dehydrating washing machine that improves the watertightness between the overflow port of the water tank and the overflow port connector inserted into the overflow port. This is what we provide. Structure of the invention The single-tank dehydrating washing machine of the invention has a synthetic resin water tank, an overflow port formed near the upper end of the tank, and an overflow port connector inserted into the overflow port, The overflow port connector includes, at the fitting portion to the overflow port,
A rib inclined toward the water tank wall side is provided at the contact part of the overflow port with the outer circumferential wall surface, and this rib is used to apply adhesive to the fitting part of the overflow port connector to the overflow port and insert it into the overflow port. The adhesive that adheres to the wall of the aquarium when the water tank is installed flows down the wall and collects in the groove formed by the wall and the rib of the overflow port connector, thereby making them watertight. It is something to keep.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the accompanying drawings.

FIG. 5 shows the overflow port connector 19 according to the present embodiment, in which 19a is a fitting portion for the overflow port 6 formed in the water tank 3, 19b is a flange portion that clamps the inner wall of the overflow port, and 19c is the overflow port The overflow port of the approximately cylindrical overflow port connection part extends upward from the fitting part 19a to the overflow port connector 19, and 19d is the fitting part that fits into the overflow port 6 formed in the water tank 3 of the overflow port connector 19. This is a rib that protrudes from 19a and is inclined with respect to the wall surface of the overflow port 6 at a contact portion with the outer circumferential wall of the overflow port 6.

If adhesive is applied to the fitting part 19a to the overflow port 6 and the overflow port connector 19 is inserted into the overflow port 6 of the water tank 3 as shown in FIG. Most of it adheres to the wall surface (shaded area A in Figure 7). Thereafter, the adhesive flows down along the wall surface to which it has adhered, but as shown in FIG. The overflow port 6 formed in the water tank 3 by collecting water in the groove formed.
This makes it easy to seal the gap between the outer circumferential wall and the overflow port connector that comes into contact with it. Although the above embodiment shows an example in which a protruding rib is formed on the overflow port connector, a recess may be formed at the abutting part between the two, and the key is to prevent the adhesive from adhering to the water tank wall surface and then flowing down. It is sufficient if there is a groove in which the agent accumulates at the contact portion.

Effects of the Invention As is clear from the above examples, the single-tub dehydrating washing machine of the present invention concentrates and drains overflowing water in one place in the event of an abnormality such as a failure of the water supply system, and does not overflow during normal use. The configuration is such that a groove is formed in the overflow port abutting part of the overflow port connection part that is inserted into the overflow port formed in the water tank by a rib that is inclined with respect to the outer peripheral wall surface of the water tank and the outer peripheral wall of the water tank, and the groove is bonded. By creating a liquid reservoir, it is possible to improve workability and watertightness, which is an important quality for washing machines, and to improve reliability.
