Gas heater/cooker

Abstract: PROBLEM TO BE SOLVED: To generate strong fire force while enhancing heating efficiency by providing a combustion chamber opening upward and receiving a cooking pan in a flat housing mountable on a table, placing a gas burner in the combustion chamber and providing an exhaust tube in the center of the cooking pan while penetrating it vertically. SOLUTION: Housing 1 of a gas heater/cooker is formed into a flat box having a relatively low height, a combustion chamber 2 opening upward is provided substantially in the center of the housing 1 and a gas burner 3 is disposed in the combustion chamber 2. A cooking pan 4 for roasting meat is placed in the upper surface opening of the combustion chamber 2 while covering the upper surface opening. A tube 5 for exhausting combustion gas of the gas burner 3 is stood from the center of the cooking pan 4 and a temperature sensor S for detecting the temperature of the cooking pan 4 by touching the lower surface thereof is fixed to the outer circumference of the combustion chamber 2. Based on the detection signal of the temperature sensor S, gas flow rate.is controlled through a thermo valve 7.

Roasting system with clean emissions and high thermal efficiency

Abstract: A bean roasting system includes a roasting chamber, a blower, a variable diverter and a controller The roasting chamber, the blower and the variable diverter each is disposed at least partially within a recirculating gas flow path The blower is configured to provide a flow stream of gas through the recirculating gas flow path The variable diverter is configured to split the gas flow path into at least two flow paths including a treated flow path and a bypass flow path The treated flow path includes a series arrangement of a gas heater and a catalytic converter The variable diverter is configured to control a percentage of a flow stream of gas that is diverted into the bypass flow path The controller is configured to activate different predetermined operating modes for the bean roasting system by controlling a state of the variable diverter and a state of the heater

Gas water heater with catching fire monitoring device and CH4 and CO alarm function

Abstract: The utility model discloses a gas water heater with a catching fire monitoring device and a CH4 and CO alarm function. The gas water heater comprises a control processor and an information detecting device in communication connection with the control processor. The information detecting device at least comprises a gas sensor and a smoke sensor. The gas sensor is used for detecting gas concentration information. The smoke sensor is used for detecting catching fire information. The control processor is respectively connected with an air valve and a relay and used for closing the air valve when receiving the information that the gas concentration detected by the gas sensor exceeds the standards, and closing the air valve and the relay when receiving the catching fire information detected by the smoke sensor. By the gas heater, gas leakage and excessive CO caused by insufficient combustion can be processed and warned effectively, and timely warnings of risky conditions such as environmental fires and self-burning-through can be given out.

Gas heater with automatic drainage freeze preventer

Abstract: The utility model relates to a gas heater with an automatic drainage freeze preventer, which comprises a heat exchanger, a water inlet tube, a water outlet tube and a controller. The gas heater is mainly and technically characterized in that the gas heater also comprises a drainage control circuit, a water sampler, a direct-flow wet type two-position four-way electromagnetic reversing valve and a water flow sensor, the direct-flow wet type two-position four-way electromagnetic reversing valve is provided with a cold water inlet end, a hot water outlet end, a first drainage end, a second drainage end, a cold water outlet end and a hot water inlet end, the water inlet of the heat exchanger is communicated with the cold water outlet end, the water outlet of the heat exchanger is communicated with the hot water inlet end, the water flow sensor is mounted at the water inlet of the heat exchanger, the water sampler is mounted in the water outlet tube, and the drainage control circuit is electrically connected with the water sampler, the direct-flow wet type two-position four-way electromagnetic reversing valve, the water flow sensor and the controller. The utility model can effectively and automatically drain water and eliminate the potential hazard that the water tube in the heat exchanger is bursted because the water in the tube is frozen when the environment temperature is low.
