Water discharge device

Abstract

The invention provides a water discharge device which can prevent reduction of flow rate in the device even though jet orifices for spraying discharge and rectification discharge are shared, and bubble mixing amount is not reduced and the device discharges bubbles and mixes the bubbles into water. Specifically, the device is characterized by including: a first member (10) including an injection port (11); a second member (20) including a streaming flow channel (23) with a streaming discharge port (21), and a shower flow channel (24) with a shower discharge port (22); and a flow channel switching mechanism. The shower flow channel (24) includes an air intake section, a storage section (24b2) of water with bubbles, a backflow prevention section, the shower discharge port (22), and a positional displacement prevention section that prevents at least a part of a projected plane, formed by projecting a downstream end of the injection port (11) in an injection direction, from being displaced outside the backflow prevention section due to an impact caused by the water injected through the injection port (11), in a state where water at a maximum flow rate is supplied into the injection port (11), and the entire projected plane passes through an inside of the backflow prevention section.

Description

technical field [0001] The present invention relates to a water discharge device which discharges water mixed with air bubbles. Background technique [0002] In Patent Document 1, there is disclosed a water discharge switching device, which includes: a first member provided with an injection port that increases the flow velocity of water flowing in from the upstream side and sprays it to the downstream side; The rectification channel of the water discharge port, the shower channel having a shower discharge port that discharges a plurality of water streams, and the channel switching mechanism switch the following states by rotating the second member relative to the first member , That is, the first state in which the water sprayed from the injection port flows into the rectification flow channel and the second state in which the water sprayed from the injection port flows into the shower flow channel. [0003] In Patent Document 2, a shower device is disclosed, which is prov...

Problems solved by technology

However, if the movement resistance is increased excessively while only considering the problem of position displacement prevention, it is not ideal because the operability at the time of water discharge switching will be deteriorated.

On the other hand, when the movement resistance of the first member and the second member is reduced in order to improve the operability at the time of water discharge switching, the following problem arises as described above. The position of the injection port and the backflow prevention part is shifted, resulting in a significant reduction in the amount of air intake

[0009] The present invention is made in view of the above-mentioned problems, and the technical problem to be solved is to provide a water spouting device that can switch between rectified water spouting and air bubble mixing spray water spouting, and prevent the jet port from The position of the backflow prevention part is shifted so that the amount of air intake is significantly reduced, and the operability at the time of water jet switching is not reduced.
