Heating apparatus using hot water and steam

Abstract

The present invention relates to a heating apparatus using hot water and steam, in which a heater receives and heats a source water to generate hot water and steam, and the mixture of hot water and steam is automatically circulated inside a heating pipe due to an expansion force of the generated steam. According to the heating apparatus of the invention, the heater is supplied with a source water and heats the source water to generate hot water and steam. The generated hot water and steam is automatically circulated inside the heating pipe in a state of mixture of hot water and steam, thereby eliminating the need for a separate circulating means for circulating the hot water and steam.

1 . A heating apparatus using hot water and steam, the apparatus comprising:
 a source water tank for storing a source water used in heating, the source water tank having an inlet port and an outlet port;   a first check valve connected to the outlet port for preventing the source water from back-flowing towards the source water tank;   a heater connected to the first check valve for heating the source water;   a heating pipe for interconnecting the heater and the inlet port of the source water tank; and   a second check valve installed between the heater and the inlet port of the source water tank and for preventing the source water circulating the heating pipe from back-flowing,   wherein the heater is penetrated internally and has a through-hole portion formed therein, the heater-passing portion being connected at one side thereof to the first check valve and being connected at the other side thereof to the heating pipe such that the source water supplied through the first check valve is heated into hot water and steam and supplied to the heating pipe in a direct-water type;   a temperature sensor coupled to one side of the heating pipe to measure a temperature of the heating pipe;   a temperature controller connected to the temperature sensor for controlling the operation of the heater according to a value measured in the temperature sensor; and   a case for accommodating the source water tank, the first and second check valves and the heater,   wherein the hot water and steam generated in the heater is automatically circulated in a state of mixture.   
   
   
       2 . The heating apparatus according to  claim 1 , wherein the heater comprises a positive temperature coefficient (PTC) heater. 
   
   
       3 . The heating apparatus according to  claim 1 , wherein the temperature controller comprises:
 a power input unit for receiving an external power;   a signal input unit coupled to the temperature sensor for receiving the value measured in the temperature sensor;   a temperature indicator for displaying the value measured in the temperature sensor;   a temperature-setting unit for setting a heating temperature;   a power output unit for supplying a power to the heater; and   a control unit for comparing the temperature value input to the signal input unit with the temperature value set in the temperature-setting unit and controlling the power to be supplied to the heater through the power output unit.   
   
   
       4 . The heating apparatus according to  claim 1 , wherein a heat-storing material is filled in an extra space of the case remaining after the source water tank, the first and second check valves and the heater are accommodated in the case. 
   
   
       5 . The heating apparatus according to  claim 4 , wherein the heat-storing material is clay ceramic or germanium.
