Claims

[Scope of utility model registration request]

(1) Steam is generated by heating the heating medium liquid 2 vacuum-sealed in the sealed container 1 with the combustion device 3, and the heated material passes through the heating tube 5 provided in the steam chamber 4 in the sealed container 1. In a vacuum hot water can configured to heat something, a closed container 1
and a bleed pump 6 are connected through a conduit 7, a bleed electric valve 8 is provided in this conduit 7, a fuel electric valve 10 is provided in a fuel pipe 9 of the combustion device 3, and a A detector 11 and a pressure detector 12 are provided, and the bleed pump 6, the bleed electric valve 8, the fuel electric valve 10, the temperature detector 11, and the pressure detector 12 are communicated with a control device 13 via a signal line, and the control device 13 calculates the partial pressure of the non-condensable gas in the closed container 1 using a calculation device in the control device 13 based on the temperature signal from the temperature sensor 11 and the pressure signal from the pressure detector 12, and calculates the partial pressure of the non-condensable gas in the closed container 1. If the partial pressure is above the set value, the electric fuel valve 10 is opened through the signal line to cause combustion in the combustion device 3, and the temperature signal from the temperature detector 11 is maintained at the set temperature,
When the set temperature is reached, the bleed pump 6 is activated, the bleed electric valve 8 is opened, and the non-condensable gas in the closed container 1 is discharged.
An oil system for a vacuum hot water can, characterized in that when the partial pressure of the non-condensable gas becomes less than a set value, the electric bleed valve 8 is turned off and the bleed pump 6 is stopped via a signal line.

(2) When the partial pressure of the non-condensable gas exceeds the set value and the bleed pump 6 and the bleed electric valve 8 are operated, the oil pump 6 is activated and after the delay time T1, the bleed electric valve 8 is opened and the non-condensable gas is When the partial pressure becomes less than the set value and the bleed pump 6 is stopped and the bleed motor operated valve 8 is closed, the oil/air motor valve 8 is closed for a delay time T
2. The oil system for a vacuum hot water can according to claim 1, wherein the bleed pump 6 is stopped after 2 hours.
