Heater

Abstract

Disclosed is a heater capable of supplying heated air to any desired place. The heater includes a heater housing having an air-inflow part and a first air-discharge port, a heating unit disposed in the heater housing to heat air, and a heated-air supply guide connected to the first air-discharge port and guiding heated air discharged through the first air-discharge port 121. The heated-air supply guide has a variable flow channel to change a heated-air supply zone. The heater can perform rapid local heating for a desired place, reduce energy consumption, and improve use convenience.

         2 . The heater according to  claim 1 , further comprising:
 a temperature sensor provided to an outlet of the heated-air supply guide to detect a temperature of the heated air.   
     
     
         3 . The heater according to  claim 2 , further comprising:
 an alarm electrically connected to the temperature sensor to warn of a danger caused by overheating.   
     
     
         4 . The heater according to  claim 1 , further comprising:
 an insulation member for preventing heat from being transferred from the first air-discharge port to the coupling part of the heated-air supply guide, wherein the insulation member is provided between the first air-discharge port and the coupling part of the heated-air supply guide and wherein the coupling part being coupled to the first air-discharge port.   
     
     
         5 . The heater according to  claim 1 , wherein the heated-air supply guide comprises a flexible material for allowing the flow channel to change. 
     
     
         6 . The heater according to  claim 5 , wherein the heated-air supply guide further comprises an outlet frame provided to an outlet of the heated-air supply guide. 
     
     
         7 . The heater according to  claim 5 , wherein the heated-air supply guide comprises one of a non-woven fabric, a cotton fabric, and a natural fabric made from natural fibers. 
     
     
         8 . The heater according to  claim 1 , wherein the heated-air supply guide is expandable and contractible. 
     
     
         9 . The heater according to  claim 1 , wherein the heater housing further comprises a second air-discharge port through which the heated air is discharged to heat a space around the heater housing. 
     
     
         10 . The heater according to  claim 9 , further comprising:
 an opening/closing device provided to each of the first and second air-discharge ports of the heater housing.   
     
     
         11 . The heater according to  claim 1 , further comprising a remote controller having a button for manipulation of the heater and display screen that displays an operating state of the heater. 
     
     
         12 . The heater according to  claim 1 , further comprising a heat sink heating air inside the heater housing, wherein the heat sink is provided in the heater housing and transfers heat from the heating unit to air inside the heater housing. 
     
     
         13 . The heater according to  claim 1 , wherein the heating unit comprises one of a coil heater, a heat pipe, and a thermoelectric semiconductor device generating heat upon an electric current. 
     
     
         14 . The heater according to  claim 1 , wherein the heating unit comprises a burner that generates heat by combustion of oil or gas. 
     
     
         15 . The heater according to  claim 1 , wherein the heating unit is separable from the heater housing to be drawn out from the heater housing. 
     
     
         16 . The heater according to  claim 1 , wherein the heated-air supply guide is detachably connected to the first air-discharge port.
