Claims

[Scope of Claim for Utility Model Registration] 1. A metal water can with a hot water outlet at the top and a water inlet at the bottom, and a plurality of ceramic heaters oriented vertically inside the water can, In the electric water heater, the water can is disposed in a state where the water is immersed in water, and the water is boiled in the process of flowing water into the can from the water supply port of the water can and flowing out of the can from the hot water outlet. Inside the water can, a plurality of plate-shaped ceramic heaters each having a width approximately equal to the width of the water can are installed. A plurality of straight water flow passages are formed in parallel in the thickness direction from the lower part where the water inlet is located to the upper part of the hot water outlet, and each of the plurality of water flow passages is connected to the heater and the water can or between the heaters. An electric water heater characterized by being as narrow as possible to the extent that the two do not touch each other. 2. In the water can, a water flow control member is interposed between the water supply port and the plurality of heaters to control the water flow from the water supply port and direct the water toward the plurality of flow paths. The electric water heater according to claim 1 of the above utility model registration claim.
