It acts to cut off the inside and outside.

Then, until the liquid W in the liquid tank 2 boils, the through hole 33
The steam is discharged to the outside from the steam vent holes 37, 37 to prevent the pressure from rising inside the space S. On the other hand, when taking out the boiling water W, the operating plate 34 is pressed and the valve 35 closes the through hole 33. When the cavity S is closed, the inside of the space S becomes high, and the hot water W can be pushed up through the hot water conduit 3 and poured out from the spout 19.

In this way, there is no need for a cock for pouring control in the hot water conduit 3 (although it goes without saying that a cock may be provided if necessary).

In addition, in the coffee boiler of this first embodiment, the hot water receiver 4
A conventional server is used as the server 4, and the strainer 6 is placed on top of the server 4.

In the coffee boiler of the second embodiment shown in FIG. 3, a large diameter opening 41 (slightly smaller diameter than the bottom surface of the server 4) is formed on the upper surface 17 of the liquid tank 2, and a surrounding wall rises slightly around the outer periphery of the opening 41. It has the shape of 42.

Annular packings 43 and 44 are attached to the peripheral edge of the opening 410 and the upper peripheral edge of the rising peripheral wall 42, respectively.

This opening 41 is hermetically closed by the bottom surface 21 of the server 4.

That is, when the lower part of the server 4 is inserted inside the rising peripheral wall 42, the bottom surface 21 of the server is inserted into the gasket 43 of the opening 41.
The outer peripheral edge of the server bottom surface 21 is brought into close contact with the gasket 44 of the rising peripheral wall 42 to airtightly close the opening 41.

In this case, the bottom surface 21 of the server directly comes into contact with the steam generated in the space S of the liquid tank 2, so that the thermal efficiency of preheating, keeping warm, etc. of the server 4 is improved.

In this embodiment, water can be supplied to the liquid tank 2 through the opening 41, so there is no need to form a special water supply port.The liquid tank 2 is provided with a pressure regulating valve 15 of the type shown in FIG. ing.
