Claims

[Claims for Utility Model Registration] 1. A container body 1 comprising a container 3 and a case 4 having a double-walled structure inside and outside, and a lid body 2 which can be opened and closed freely, and which covers the lower surface of the lid body. Protective plate 4
A sealing member 52 is provided around the peripheral edge 44a of the container 3, and the annular receiving part 3 receives the sealing member at the opening of the container.
In a water heater provided with a: the protection plate 44
is a tapered portion 4 that slopes downward from the periphery in the centripetal direction.
4b, and the tapered part and the opening inner peripheral part 3 of the container.
an introduction space 53 that gradually becomes narrower toward the seal member 52 is formed between the seal member 5 and the seal member 5;
Reference numeral 2 denotes a holding part 52a that holds the peripheral edge 44a of the protection plate 44, and a seal that extends downward from the holding part, reaches the annular receiving part, and projects in the inner circumferential direction beyond the annular receiving part. 52b and a pressure receiving chamber 56 formed between the tapered portion and the tapered portion on the inner peripheral side of the seal portion and opening facing the introduction space; Device. 2. The lid body 2 incorporates an air pump 26 that pumps air into the container 3, and also forms a steam passage 39 that communicates the inside of the container 3 with the outside air when the lid is closed; A utility model registration claim characterized in that the switching valve 27 allows the steam passage 39 to communicate with the inside of the container 3 when the pump is not in operation, while cutting off the communication between the steam passage 39 and the container 3 when the pump is in operation. Range 1 or 2
A steam venting device for a water heater as described in 2.
