BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rectifying water discharging mechanism in which a rectifying network is provided at the tip of a water discharging port.

[0002]

2. Description of the Related Art Conventionally, a rectifying water discharging mechanism having a rectifying net and / or a rectifying plate at the tip of a water outlet is widely used. In the case of connecting a device with low pressure resistance such as an electric water heater, a device using a rectifier network may cause internal pressure of the connected devices to rise due to clogging of the rectifier network, etc. Since there is a possibility that the internal pressure may increase, only the current plate is used to prevent the internal pressure of the connected devices from increasing.

[0003]

However, the rectifying water discharge mechanism using only the rectifying plate has a problem in the case of water discharge conditions, for example, when the internal shape of the water discharge port is complicated or the passage before discharging water is short. However, the water discharge state is disturbed, and a sufficient effect cannot be obtained as a rectification water discharge mechanism. The present invention has been made in view of the above-mentioned problems of the related art, and aims to prevent an increase in internal pressure of equipment connected upstream and obtain excellent rectified water discharge which is not affected by water discharge conditions. I do.

[0004]

In this invention the rectifier spouting mechanism in order to achieve the above object, according to an aspect of, and a sprinkler plate rectifying network to the distal end of the spout, the said sprinkling plate receiving the flowing water,
A resistance portion that changes the flow direction and guides the flow to the net portion of the rectification network is provided, and a hole for preventing an internal pressure rise is formed in a position corresponding to the resistance portion in the rectification network.

[0005]

In the rectifying water discharge mechanism configured as described above, the water flow reaching the discharge port flows through the sprinkler plate to the lower rectifier net, but is received by the resistance portion of the sprinkler plate.
The direction of the flow is changed and guided by the net of the
In order not to flow directly into the internal pressure prevention holes of the
When the dust passes through the mesh portion and is rectified and discharged, and the net portion of the rectification net is clogged with dust, the dust flows from the mesh portion into the internal pressure prevention hole and is discharged through the hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, A denotes a water outlet, B denotes a rectifying cap screwed to the outer peripheral surface of the tip end thereof, and a water spray plate a is provided in the water outlet A; c is deployed.

The water spray plate a is an integrally molded product of a synthetic resin such as polypropylene, and has a shape in which two strip plates having a length substantially corresponding to the inner diameter of the tip end of the water outlet A are combined in a plane cross shape with the plate surface upright. In addition, a disk-shaped resistance portion 1 which becomes a resistance of flowing water is integrally provided on the upper surface of a central portion thereof, and is fitted and mounted to a tip end of the water discharge port A so as to be orthogonal to its axis.

[0008] The rectifying net b is formed by knitting a metal wire such as stainless steel in a net shape, and is formed in a circular shape having substantially the same diameter as the opening at the tip of the water outlet A, and its peripheral edge is used to prevent fraying of the metal wire. It is folded and crushed to provide strength. The rectifying network b has an inner pressure prevention hole 2 formed in the center by punching it into a circular hole having substantially the same diameter as the resistance portion 1 of the rectifying plate a. And this rectifier network b is a rectifier cap B
And placed on a rectifying plate c mounted below the rectifying cap B so that the rectifying cap B is screwed into the water discharge port A. 3
Is engaged with the notch 4 formed on the lower surface of the tip of the sprinkler plate a to be sandwiched between the sprinkler plate a and the rectifier plate c.

The rectifying plate c is formed by bending a metal band plate into a chrysanthemum flower shape or a star shape. The rectifying plate c is fitted and disposed in the lower portion of the rectifying cap B so as to be located downstream of the rectifying network b. It is fixed to.

The resistance portion 1 of the water spray plate a receives flowing water.
In addition, the flow direction is changed, and the flow is guided to the net portion of the rectification net b. As shown in FIGS. It may be formed in a conical shape at the center of the upper surface of the plate a. Further, the resistance portion 1 does not necessarily need to be provided at the center of the water spray plate a, but is provided in a ring shape at the peripheral portion, or is partially provided in an island shape at a desired position in a circle drawn by connecting the tips of the water spray plate a. It is also possible. However, in such a case, the internal pressure prevention hole 2 of the rectification network b should not be provided at the center of the rectification network b, but should be provided at a position corresponding to the resistance portion 1 and in a shape corresponding to the resistance portion 1. It is. Further, the resistance portion 1 may be a net-like shape or a plate having a large number of fine holes.

On the other hand, the rectification network b may be one as shown in FIG. 1 or more than one as shown in FIG. 4, and as shown in FIG. When it is provided, there is no need to intentionally provide the current plate c downstream thereof.
However, when a plurality of rectification networks b are provided in an overlapping manner, it is needless to say that the internal pressure prevention holes 2 must be provided at the same locations on all the rectification networks b.

[0012]

[Effect] Since the present invention is configured as described above, the following effects can be obtained. (1). The water flow discharged from the discharge port passes through the sprinkler plate and flows to the lower rectifier net.
The direction of the flow is changed by the part
And should not normally flow directly into the internal pressure prevention hole.
The device is connected to the upstream side because it flows through the internal pressure prevention hole and is discharged through the hole when clogging or the like occurs in the net portion. There is no danger of raising the internal pressure of connected devices by applying back pressure to the devices. Therefore, even if the equipment connected to the upstream side is equipment with low pressure resistance, such as a hot-water storage type hot water heater, water purifier, electric water heater, etc., the internal pressure rises due to clogging of the rectification network, etc. No damage will occur. (2). On the other hand, when there is no clogging in the net of the flow straightening network, the flowing water hardly passes through the internal pressure prevention holes of the flow straightening net, and the net is guided by the resistance portion of the water spray plate to the net of the straightening net. Rectified by passing through, the passage to the water outlet is complicated, and the straight part of the passage to the front end of the water outlet is not affected by discharge conditions such as a short length. Good rectified water discharge is obtained.
