Document Type and Number:
Japanese Patent JP6040380
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a branch pipe unit capable of detecting a flow state of a fluid at the time of hot water supply and circulation by one detection means, and capable of improving the detection accuracy.SOLUTION: A branch pipe unit comprises: a first flow passage 108 having a first opening end 102 and a second opening end 104 at both ends, and including a linear flow passage part 106 in-between; an axial flow impeller 114 arranged in the linear flow passage 106, and having a rotational axis 112 extending in the direction along a flow of hot water passing through the linear flow passage 106; a second flow passage 126 having a third opening end 124 at one end, and in which the other end communicates with the second opening end 104 side of the first flow passage 108; a bypass flow passage 140 for communicating the first flow passage 108 and the second flow passage 126, and for supplying the hot water flowing in from the third opening end 124 to the position capable of rotating the axial flow impeller 114; a detection part 116 for detecting a rotation state of the axial flow impeller 114; and a check valve 142 for intercepting the hot water flowing in from the first opening end 102 from passing through the bypass flow passage 140.
