Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an improvement in the water inlet of a washing machine for washing clothes, etc.

BACKGROUND ART The structure of a water inlet in a conventional washing machine of this type will be explained with reference to FIGS. 6 and 7. Water is poured into the washing tub through a water inlet main body 2 via a water supply hose 1 communicating with a water valve built into the upper part of the washing machine main body. This water inlet main body 2 includes a water inlet holder 5 having a water inlet 3 and a water flow direction guide 4 which are connected to the water supply hose 1, a water inlet guide 6 inscribed in and covering the water inlet holder 5, and the water inlet holder 5 and water inlet. A rectifying filter 7 made of cloth or the like is sandwiched between the guides 6. The water inlet main body 2 is inserted and fitted into upper body partition ribs 8, 8' forming the upper part of the washing machine.

Problems that the invention aims to solve In this configuration, due to changes in the water pressure of tap water,
When the pressure increases, water flows upward, flows out from the gap between the water injection holder 5 and the water injection guide 6 in the direction a, and drips outside the washing tub, or the water injection state changes due to density variations in the rectifier filter 7. As a result, water is injected separately to both ends of the water injecting holder 5 (arrow c), the pressure is high at the center of the water injection, and the amount of water protruding is also large at the center, resulting in a state as shown by arrows b and c, and the water injection state This had a negative effect on the ability of the foam to disappear during rinsing and on the way water splashed onto clothes due to uneven water flow.

This invention not only solves these problems, but also eliminates the factors caused by variations in the density of soft cloth, etc., and ensures stable water injection with only a molded product. It provides a water inlet.

Means for Solving the Problems In order to achieve the above object, the present invention has a collision surface on which the water from the hose connection port collides approximately perpendicularly, and this collision surface has a collision surface approximately coaxial with the water supply direction. A plurality of rectifying pins are provided, and shielding ribs are arranged to cover the plurality of rectifying pins in an eight-shaped pattern, and a plurality of notched holes are provided in the shielding ribs. A space is provided in the space.

Effect With this configuration, even when the water pressure of tap water is high, the shielding ribs provided in the 8-shape shape and the notch holes provided in the shielding ribs allow the water that hits the collision surface to flow through the shielding ribs and the notched holes. The buffer equalizes the distribution of water within the water inlet main body, resulting in a state in which water is injected evenly downward. When the water pressure is low, it is equalized only by the rectifier pin, but the key point is that when the water pressure is at maximum, the shielding rib and cutout hole suppress and buffer the water flowing upward within the water inlet main body, thereby maximizing the effect. This eliminates water leakage from the top of the water inlet and is unaffected by changes in water pressure.
This ensures uniform water injection at all times.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings. In FIG. 1, water is poured into a washing tub/dehydration tub 10 built into the washing machine main body 9,
Clothes are washed by rotating and agitating the agitating blades 11. Water is supplied through a pressure hose 12 connected to a water faucet, and a water supply valve 1 is built into the upper part of the main body 9.
3 is connected to the water inlet main body 15 via a water supply hose 14. In Figure 2, the water inlet main body 1
5 has a hose connection port 16 that can be connected to the water supply hose 14, and a collision surface 17 with which water from the hose connection port 16 collides approximately perpendicularly.
A plurality of cylindrical rectifying pins 18 are provided approximately coaxially with the water supply direction, and shielding ribs 19 are provided to cover the rectifying pins 18 in an eight-shaped manner as shown in FIG.
This shielding rib 19 is provided with a plurality of notched holes 20 as shown in FIG. has been established. As shown in FIG.
a water flow direction guide 22 that guides water into the holder, a water filling holder main body 15a consisting of a hose connection port 16, a shielding rib 19, a fixing stripper 24, etc.;
The collision surface 17 and the water injection guide main body 15b consisting of the rectifying pin 18 are integrally formed with a plastic resin or the like via the aluminum part 23.

A plurality of guides 25 are provided on the water inlet holder main body 15a, and these guides are set as appropriate depending on the size of the water inlet main body 15. In Fig. 2, the rear part 23
The figure shows a state in which the water inlet guide main body 15b is rotated using the bending axis and is set so as to be inscribed in the water inlet holder main body 15a, and the water inlet main body 15 is connected to the clothing input port of the body upper frame 26 that constitutes the upper part of the washing machine main body 9. It is inserted and fitted between the wall ribs 28 of 27 and fixed by a fixing stopper 24.

The water passed to the hose connection port is passed through the rectifier pin 18,
The pressure is suppressed by the collision surface 17, and especially when the water pressure increases, the shielding rib 19 and the notch hole 20 act to suppress and buffer the water flowing upward.
Stable water injection conditions can be obtained even under high pressure.

The cutout hole 20 provided in the shielding rib 19 is appropriately set with consideration given to the size of the water inlet and the inflow balance with the space 21.

In this embodiment, the water inlet of a washing machine has been described, but the invention is not limited to this, and can be applied to any device that injects water that requires rectification.

Effects of the invention As described above, according to the invention, the water from the hose connection port has a collision surface that collides approximately vertically, and this collision surface has a plurality of rectifying pins approximately coaxial with the water supply direction. A shielding rib is provided to cover the plurality of rectifying pins in an eight-shaped configuration, and a plurality of notched holes are provided in the shielding rib, and a space is provided in the upper left and right sides of the water inlet main body through the shielding rib. Because of this, it is not affected by changes in water pressure and always provides good, even water injection, which eliminates problems such as poor foam removal during rinsing due to uneven water injection and water splashing on clothes. It eliminates the need for conventional products due to density variations such as thick cloth, and can be constructed using only molded products, ensuring stable water injection.
In addition, since it can be constructed from a single component, it can be manufactured at low cost and is highly mass-producible, which has great practical effects.
