DRAIN VALVE DEVICE, WASHING WATER TANK DEVICE WITH THE DRAIN VALVE DEVICE, AND WATER CLOSET WITH THE WASHING WATER TANK DEVICE
PROBLEM TO BE SOLVED: To provide a drain valve device capable of effectively restraining reduction in an instantaneous flow rate of washing water.SOLUTION: A drain valve device 8 includes: a body part 18 having a drain port part 14 attached to a drain port 6b formed on a washing water tank 6, and a valve element for opening and closing the drain port part; and a cylindrical body 20 attached to the body part. The cylindrical body includes a lower opening part 46 attached to the drain port part of the body part attached to the washing water tank, a bottom surface part 48 protruding to an outer peripheral side from the lower opening part and forming a bottom surface of the cylindrical body, a side wall part 50 protruding upward from the bottom surface part and surrounding the body part, and an upper opening part 52 continued to an upper end of the side wall part. A curved surface is formed on the upper opening part of the cylindrical body in such a manner of separating from the body part toward the upper end from the lower end.SELECTED DRAWING: Figure 4
【課題】洗浄水の瞬間流量が低下することを効果的に抑制することができる排水弁装置を提供する。【解決手段】排水弁装置８は、洗浄水タンク６に形成された排水口６ｂに取り付けられる排水口部１４及びこの排水口部を開閉する弁体を備えた本体部１８と、この本体部に取り付けられる筒体２０と、を有し、この筒体が、洗浄水タンクに取り付けられた本体部の排水口部に取り付けられる下側開口部４６と、この下側開口部から外周側に突出して筒体の底面を形成する底面部４８と、この底面部から上方に伸びて本体部を取り囲む側壁部５０と、この側壁部の上端と連続する上側開口部５２と、を備え、筒体の上側開口部に、その下端から上端に向かって本体部から離間するように湾曲面が形成されている。【選択図】図４
