Description

  The present invention refers to a switch faucet that can be directly connected to a water tap (for example, a switch tap that simply switches between tap water straight water discharge / tap water shower water discharge, a water purifier integrated with a switch faucet (so-called faucet direct water purifier, and various mineral additions). In general, tap water straight water discharge / tap water shower water discharge / treated water (purified water) water discharge is possible by switching the lever.), Switch tap separation type water treatment device (water treatment device is a stationary water purifier, mineral water generation) Applicable to water heaters, water coolers, alkaline ion water conditioners, etc. Usually, a water treatment device and a change-over plug are connected by a water supply hose, etc. The change-over plug for the water treatment device is a 1-way type (water treatment device) Can be used for branch water supply, usually tap water straight water discharge / tap water shower water discharge / water treatment device branch water supply by lever switching, 2-way type (branch water supply to water treatment device, water treatment device Processing from (Tap water straight water discharge / water treatment device water discharge, or tap water straight water discharge / tap water shower water discharge / water treatment device water discharge is possible by switching the lever.) , Etc.)). ] It is related with improvement of the tap water shower spout which has the favorable rectification effect of the tap water shower spout.

  Conventionally, in order to reduce the water supply sound discharged from the faucet or the sound falling from the sink, etc., or to eliminate water splashing, for example, a foam generating device is placed in the faucet cap, and the faucet cap is What is solving the problem by screwing into the faucet spout (structurally, the air gap between the tube container and the faucet cap is an air inlet) to produce foam spout It was general. Although rarely, when the tap water pressure is lower than the predetermined pressure, tap water is discharged from the air introduction slit of the cylindrical container, and the water discharge state in which the quality of the foam discharge is impaired (for example, water from the outlet) Rectified water spouting with drops that cause leakage.) (See, for example, Patent Documents 1, 2, and 3).

  And recently, water purifiers such as water purifiers, alkaline ion water purifiers, water coolers, etc. have become widespread, and the faucets are equipped with a switch faucet integrated water purifier (the valve body is a ball valve system, for example, a patent Refer to Document 4. For the valve body, refer to, for example, Patent Document 5), and the switch plug for the switch-switch-type water treatment device (for 1-way type, for example, refer to Patent Document 6. For 2-way type) (See Patent Document 7)), etc. (such as tap faucet fixing parts, upper case, valve body, lever provided on the right side of the valve body, shower cap, tap water shower spout) And a lower case having a tap water straight spout, and in conjunction with the lever, the tap water straight spout, tap water shower spout switching, or tap water straight spout, tap water shower spout, water treatment The structure of the valve body can be switched operating vessels treated water spouting, for example, a ball valve type, drum valve system, seat valve type, a spool valve system, etc..) Now is attached.

As an improvement example of tap water shower water discharge, what provided the partition rib in the tap water shower water discharge port of the inner surface side of a lower case is known (for example, refer to patent documents 8).
Further, there is known a tap water shower outlet having a tapered shape and slightly decentered (see, for example, Patent Document 9).
