(57) [Abstract] [Purpose] Prevents the internal pressure of the equipment connected upstream from rising due to clogging of the rectifying network installed at the water outlet,
Moreover, the present invention provides a straightening / water-discharging mechanism that can obtain excellent straightening / water-discharging regardless of water-spraying conditions. [Structure] A water sprinkling plate and a straightening plate are arranged at the tip of the spout with the former as the upstream side, and the sprinkling plate is provided with a resistance portion that serves as a resistance to running water, and a position corresponding to the resistance portion is provided on the straightening net. An internal pressure rise prevention hole is formed in the guide hole, and the water flow is normally guided by the resistance part of the water spray plate to the net part of the rectification net so that it does not directly flow into the internal pressure prevention hole of the rectification net. When the mesh portion of the rectifying mesh is clogged with dust or the like, running water is caused to flow from the mesh portion to the internal pressure preventing hole, pass through the hole, and are discharged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rectifying and discharging mechanism in which a rectifying mesh is arranged at the tip of a water discharge port.

[0002]

[Prior Art]

 Conventionally, a rectifying water discharge mechanism having a rectifying net or a rectifying plate at the tip of the water discharge port or both of them has been widely used, but a hot water storage type water heater, water purifier, electric water heater of the original stop type is provided on the upstream side. In the case of connecting equipment with low iso-pressure resistance, in the case of using a rectifying net, the internal pressure of the connected equipment may rise due to clogging of the rectifying net, etc., leading to water leakage or tank rupture. Therefore, only the current plate is used to prevent the internal pressure of connected devices from rising.

[0003]

[Problems to be solved by the device]

 However, the rectifying and discharging mechanism using only the rectifying plate is disturbed by the rectifying and discharging mechanism when the water discharging condition is complicated, for example, when the internal shape of the discharge port is complicated or the passage until discharging water is short. As a result, a sufficient effect cannot be obtained. The present invention has been made in view of the above problems of the prior art, and an object thereof is to prevent an increase in internal pressure of devices connected to the upstream side and to obtain excellent rectified water discharge that is not affected by water discharge conditions. And

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, in the rectifying and discharging mechanism of the present invention, a sprinkling plate and a rectifying net are arranged at the tip of the spout with the former as the upstream side, and the sprinkling plate is provided with a resistance part which becomes a resistance of running water. The rectifying net is formed with an internal pressure increase preventing hole at a position corresponding to the resistance portion.

[0005]

[Action]

 In the rectifying / water-discharging mechanism configured as described above, the water flow reaching the discharge port passes through the water spray plate and flows to the lower rectifying net. It is prevented from flowing directly into the prevention hole and is guided to the mesh portion of the rectifying mesh, and is discharged after being rectified after passing through the mesh portion. Flow from the portion to the internal pressure prevention hole, pass through the hole, and are discharged.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, A is a spout, and B is a rectifying cap screwed onto the outer peripheral surface of its tip. A sprinkler plate a is provided in the spout A, and a rectifying net b and a rectifying net are provided in the rectifying cap B. Board c is deployed.

The water sprinkling plate a is an integrally molded product made of synthetic resin such as polypropylene, and has a shape in which two strips having a length substantially corresponding to the inner diameter of the tip of the spout A are combined in a plane cross shape with the plate surfaces standing upright. It has a disc-shaped resistance portion 1 which is formed in a circular shape and serves as a resistance against running water on the upper surface of the central portion thereof, and is fitted and attached to the tip end portion of the water discharge port A so as to be orthogonal to the axis thereof. It

The rectifying mesh b is formed by braiding a metal wire made of, for example, stainless steel into a mesh shape, and is formed in a circular shape having substantially the same diameter as the opening at the tip of the water discharge port A, and its peripheral portion prevents fraying of the metal wire. It is folded and crushed in order to give strength. Further, the rectifying net b is formed by punching out an internal pressure preventing hole 2 in the center thereof in the shape of a circular hole having substantially the same diameter as the resistance portion 1 of the rectifying plate a. The straightening net b is housed in the straightening cap B so as to be orthogonal to the axis of the straightening net b and placed on the straightening plate c attached to the lower part of the straightening cap B, and the straightening cap B to the spout A is removed. The bent and crushed portion 3 at the peripheral portion is engaged with the notch 4 formed on the lower surface of the tip of the water spray plate a by screwing, and is sandwiched between the water spray plate a and the current plate c.

The rectifying plate c is formed by bending a metal band plate into a chrysanthemum shape or a star shape. The rectifying plate c is fitted in the lower part of the rectifying cap B so as to be located downstream of the rectifying net b, and is elastic by its elasticity. It is fixed to the section.

The resistance part 1 of the water spray plate a guides the running water to the net part of the rectifying net b, and is formed in a disc shape in the vertical middle part of the water spray plate a as shown in FIGS. Of course, a conical shape may be formed in the central portion of the upper surface of the water spray plate a. Further, the resistance part 1 does not necessarily have to be provided in the central part of the water spray plate a, but may be provided in a ring shape at the peripheral edge part or partially in an island shape at a desired portion within a circle drawn by connecting the tips of the water spray plate a. It is also possible to provide. However, in such a case, the internal pressure prevention hole 2 of the rectifying network b 1 should not be provided in the center of the rectifying network b, but at a position corresponding to the resistance portion 1 and in a shape corresponding to the resistance portion 1. Is. Furthermore, the resistance part 1 may be a mesh or a plate having a large number of fine holes.

On the other hand, the rectifying network b may be one sheet as shown in FIG. 1 or more sheets as shown in FIG. 4, and about three sheets are stacked as shown in FIG. When it is provided, it is not necessary to intentionally provide the current plate c on the downstream side. However, when a plurality of rectifying nets b are provided in an overlapping manner, needless to say, the internal pressure preventing holes 2 must be provided at the same locations on all the rectifying nets b.

【effect】

 Since the present invention is configured as described above, it has the following effects. (1). The water flow discharged from the discharge port flows through the sprinkler plate to the lower flow straightening net, and is normally prevented by the resistance part of the water sprinkling plate so as not to flow directly into the inner pressure prevention hole of the straightening net. It is guided to the mesh part of the machine and is discharged after being rectified after passing through the mesh part, but if clogging occurs in the mesh part, it flows into the internal pressure prevention hole and is discharged through this hole, so the upstream side There is no fear of exerting a back pressure on the equipment connected to and increasing the internal pressure of the equipment connected. Therefore, even if the device connected to the upstream side is a device with a small pressure resistance such as a hot water storage type hot water supply device of the original stop type, a water purifier, an electric water heater, leakage of water or tank due to increase in internal pressure due to clogging of the rectifying network No damage such as destruction will occur. (2). On the other hand, if there is no clogging in the mesh portion of the flow straightening net, almost no running water will pass through the internal pressure prevention holes of the flow straightening net, and the net will remain guided to the net portion of the flow straightening net by the resistance part of the water spray plate. Since it is rectified after passing through the section, the passage to the spout is complicated, and the straight part of the passage to the tip of the spout is not affected by discharge conditions such as being short. Good rectified water discharge can be obtained even under discharge conditions.
