It is configured to be appropriately suppressed. Then, when the leaf spring comes into contact with the front side of the locking piece, the blowing device closes the pouring port, blows the vapor through the blowing portion of the blowing device, and opens the lever by opening the lever. The spring changes the contact position with respect to the locking piece and contacts the top of the locking piece to maintain the spout open.

Therefore, when the hot water in the kettle is not in a boiling state, the blowing part of the blowing device surely closes the pouring spout of the kettle so that the boiling water and the water vapor inside passes through the blowing part. A buzzer is emitted to inform that it is in a boiling state, and when the amount of passing steam increases, the blowing part is appropriately raised by the steam pressure to allow the steam to escape appropriately and prevent an excessive rise in the internal pressure. Can secure safety. In addition, when pouring hot water, the lever is operated to open the pouring port by raising the sounding part by turning, and changing the contact position of the leaf spring with the locking piece to maintain the open state. It is possible to maintain the water temperature, which allows the hot water to be tilted so that the hot water can be poured out from the pouring port.The blowing device does not inadvertently close during hot water pouring, so it can be used safely. be able to.
