った。Here, when directly connected to the water supply equipment, if a detergent with high foaming properties is used and a lot of foam is generated and reaches the vicinity of the water supply port 16, if the water supply equipment becomes negative pressure, the foam will be generated more forcefully. , invade inside the water supply equipment. In order to prevent this backflow of bubbles, as shown in Figure 2, the water supply hose 17 and water supply port 18 are
The ball 19 is connected to the seal surface 17-a and the lip 1.
8-a, and when the water supply hose 17 side becomes negative pressure, the ball 19 is attracted to the negative pressure side and seals the flow path. In order to prevent this, it is necessary to make a downward slope from the water supply hose to the water supply port. Due to this slope, the ball 19 is normally located near the lip 18-a, which is farther away from the sealing surface 17-a, so the water supply hose There is a problem in that when the pressure on the 17 side becomes negative, the ball 19 cannot be reliably attracted to the ball 19.

The water supply hose has a substantially arc-shaped water supply hose with sealing properties, a water supply port, a large-diameter portion connecting the water supply hose and the water supply port, and a backflow prevention ball that is slidable on the large-diameter portion. The large-diameter portion has a slope that becomes lower toward the water supply hose, and the sliding portion of the backflow prevention ball is sloped to ensure backflow prevention.

In Figure 0, 2o is a water supply hose connected to a water supply equipment, and the hole at the end 21 of which serves as a flow path is arc-shaped. and has sealing properties.

状をしている。Further, the end portion 21 has a larger diameter and serves as a connecting portion 23 into which the water supply port 22 is fitted.The connecting portion 23 has a larger diameter and is further lowered toward the water supply hose side. It's slanted like that. The backflow prevention ball is a spherical body larger than the diameter of the hole in the end portion 21 of the water supply hose, and is slidably mounted within the connecting portion 23. As shown in FIG. 4, the end portion 26 of the water supply port 22 has a large diameter portion 26 having a cylindrical shape and a small diameter portion 27 having an elliptical shape.

ことはない構成と々っている。To explain the operation in the above configuration, when water is supplied, the ball 24 is pressed against the water supply port end 26 by the pressure of water supply from the water supply equipment as shown in FIG. 4, but the hole at the end is oval shaped. Water is supplied without blocking the flow path. When the water supply is finished, the ball 24 rolls along the slope of the connecting portion 23 and is positioned on the end 21 side of the water supply hose 20 as shown in the figure. In this state, if the water supply equipment side becomes negative pressure and bubbles generated during washing are sucked in from the water supply port, the ball 24 will be attracted to the end 21 of the water supply hose 2o as shown in the figure. The sealability of the end 21 seals the flow path and prevents bubbles from flowing into the water supply equipment. The flow path of the water supply hose 20 and the water supply port 22 has an inclination in a direction downward toward the water supply port, and the entire flow path is not filled with water at each part of the flow path, but water accumulates in the water supply device. The structure is such that it will not be destroyed even if the water freezes.
