Abstract: Object: To provide a shower device suitable for use during a midday break by setting a temperature of discharged hot water reaching (landing in) a part corresponding to a user's neck (in particular, a back middle portion of the neck) to a relatively low temperature and setting a temperature of discharged hot water reaching (landing in) other areas of the user to a relatively high temperature. Resolution means: A water discharge device according to the present invention includes a first water discharge unit configured to discharge hot water toward a first discharge range corresponding to a neck of a user who is to be at a predetermined position, and a second water discharge unit configured to discharge hot water toward a second discharge range to the user below the first discharge range, wherein a temperature of the hot water when the hot water reaches the user after having been discharged from the first water discharge unit is lower than a temperature of the hot water when the hot water reaches the user after having been discharged from the second water discharge unit.

Abstract: There is provided a water discharge device including: a first member including an injection port; a second member including a streaming flow channel with a streaming discharge port, and a shower flow channel with a shower discharge port; and a flow channel switching mechanism. The shower flow channel includes an air intake section, a storage section of water with bubbles, a backflow prevention section, the shower discharge port, 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 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, in a state where water at a maximum flow rate is supplied into the injection port, and the entire projected plane passes through an inside of the backflow prevention section.

Abstract: The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.

Abstract: A water discharge device that discharges water while reciprocally vibrating the water. The water discharge device includes a water discharge device body and a vibration generating element. The vibration generating element includes a water supply path, a collision portion, a vortex street path, and a discharge path. The vortex street path is formed by fitting an upstream fitting portion of an upstream member and a downstream fitting portion of a downstream member to each other. The upstream member or the downstream member is provided with a vibration reducing portion that reduces vibration of the upstream member due to vortices generated in the vortex street path. The upstream fitting portion or the downstream fitting portion is elastically deformed by a predetermined amount due to the provision of the vibration reducing portion.
