Abstract
The present invention provides a water heating device capable of shortening a flow passage that mixes hot water and cold water and saving space in the device. In a flow path cross section of circular orthogonal to the central axis of the flow path, the flow inlet has an outer wall extending from the inner peripheral surface of the flow path in a direction of a tangent of the inner peripheral surface, and the central axis of the flow inlet is disposed closer to the inner peripheral surface of the flow path connected to the outer wall with respect to the central axis of the flow path.
Claims6
A water heating device for mixing hot water and cold water and supplying the mixture, the water heating device comprising:
- a hot-water flow inlet serving as a flow inlet through which the hot water flows in;
- a cold-water flow inlet serving as a flow inlet through which the cold water flows in;
- a flow path through which a hot water mixture, obtained by mixing of the hot water and the cold water, flows;
- and
- a flow outlet through which the hot water mixture flows out,
- wherein
- an inner peripheral surface of the flow path is formed in a cylindrical shape, the hot-water flow inlet and the cold-water flow inlet are formed on one end side of the flow path, and the flow outlet is formed on the other end side of the flow path, and
- a flow inlet that is at least one of the hot-water flow inlet and the cold-water flow inlet is opened on the inner peripheral surface of the flow path, and in a flow path cross section of circular orthogonal to a central axis of the flow path, the flow inlet has an outer wall extending from the inner peripheral surface of the flow path in a direction of a tangent of the inner peripheral surface, and a central axis of the flow inlet is disposed closer to the inner peripheral surface of the flow path connected to the outer wall with respect to the central axis of the flow path.
