Embodiment Construction

[0039] figure 1 (a), (b) are respectively the front view which shows the 1st Embodiment of the shower head of this invention, figure 1 A-A sectional view in (a). figure 2 yes figure 1 Perspective view of the shower head shown in (a), (b).

[0040] The shower head 1 has a head body 2 , a water diffuser plate 3 , and a hot water spray flow path 4 .

[0041] A hot water introduction channel 30 is formed inside the head main body 2, and a gas-liquid mixing unit 11 is provided on the upstream side of the introduction channel 30. The gas-liquid mixing unit 11 sucks gas by depressurizing when introducing hot water, The attracted gas is mixed into the hot water as bubbles.

[0042] The water diffuser 3 has a flat portion. A plurality of water spray holes 31 are formed through the plate-shaped portion along the plate thickness direction. Such a diffuser plate 3 is arranged outside the outlet 28 of the introduction flow path 30 and attached to the head main body 2 .

Abstract

In a shower head including a head main body provided with a gas-liquid mixing portion, a spray plate having a plurality of spray apertures, and a discharge path formed between the head main body and the spray plate, an introducing path has an enlarged path at a side of an exit of the introducing path and a discharge path is disposed perpendicular to a side of an exit of the introducing path and an entrance of the discharge path has a cross-sectional area at which a volume of the warm or cold water flowing into the discharge path per unit time is equal to or less than a volume of the warm or cold water passing a portion except the enlarged path of the introducing path per unit time.

Description

technical field [0001] The present invention relates to a shower head that sprays hot water mixed with fine air bubbles from water spray holes. Background technique [0002] Microbubbles with a diameter of 50 μm or less mixed in hot water can absorb and remove a large amount of dirt such as human sebum due to their large specific area. The smaller the diameter of the fine air bubbles, the larger the specific area. Therefore, it is desirable to reduce the diameter of the fine air bubbles as much as possible in order to improve the cleaning function as described above. [0003] Patent Document 1 below describes a liquid discharge device capable of generating fine air bubbles efficiently and at a high density. This liquid ejection device can be used in a shower head. [0004] In the liquid ejection device described in Patent Document 1, the liquid introduction path, the liquid flow circulation path connected to the upstream side of the liquid introduction path, the narrowed f...
