Abstract
The present invention relates to a portable boiler for a hot mat, which comprises: a water reservoir, one side of which has an inlet pipe for introducing water circulating through the hot mat, and which stores the water; a heat transfer unit in which the water discharged from the water reservoir flows along a flow channel pipe to be heat exchanged, wherein the water is discharged to the hot mat via an outlet pipe formed at one side thereof; a heating unit which burns the fuel gas fed from a fuel tank to heat the water in the heat transfer unit; and a housing which forms the outer appearance of the boiler.
Claims12
A portable boiler for a heating mat comprising:
- a water reservoir storing circulating water that is received through an inlet tube disposed on one side of an upper portion of the water reservoir;
- a heat-transfer part allowing the circulating water to flow along a flow passage to exchange heat and discharging the circulating water to a heating mat through an outlet tube disposed on one side of the heat-transfer part;
- a heating part for heating the circulating water inside the heat-transfer part by burning fuel gas supplied from a fuel tank;
- a housing defining an exterior of the portable boiler;
- a heat-collecting plate on an undersurface of the heat-transfer part to increase thermal conductivity,
- wherein the water reservoir comprises:
- the inlet tube connected to one end of a circulation pipe buried in the heating mat on the one side of the upper portion of the water reservoir;
- a fixing bracket having a plurality of holes to allow the circulating water to flow into the heat-transfer part;
- a check valve formed of a thin film and opening or closing the plurality of holes according to a water pressure of the circulating water;
- and
- a temperature sensor sensing a temperature of the circulating water to generate a physical signal using expansion and contraction of a liquid filled therein;
- wherein the heat-transfer part has the flow passage that allows the circulating water to absorb heat when the check valve is opened and the circulating water flows therein;
- wherein the heating part comprises:
- a gas controller for controlling an injection amount of the fuel gas supplied from the fuel tank;
- a controller receiving the physical signal from the temperature sensor to control the gas controller;
- and
- an igniter comprising a combustor for burning the fuel gas supplied from the gas controller and a spark plug generating an electric spark on the combustor,
- wherein the flow passage of the heat-transfer part comprises:
- a vertical flow passage to which the circulating water first flows through the check valve of the water reservoir;
- a bypass flow passage detouring the circulating water from the vertical flow passage to one side;
- an inclination flow passage communicating with the bypass flow passage and inclining toward the outlet tube,
- wherein the portable boiler further comprises a shield plate disposed between the inclination flow passage and the bypass flow passage of the heat-transfer part to prevent heat transferred from the heat-collecting plate from being transferred to the water reservoir through the flow passage.
