연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A control system for a gas grill having a cooking surface, comprising: at least two fuel flow valves located between a fuel source and at least one grill burner of the gas grill, wherein the at least two fuel flow valves comprise at least two electronically operated fuel flow valves configured in a parallel relationship relative to the fuel source, one of the at least two electronically operated fuel flow valves comprising a high flow valve, and an other of the at least two electronically operated fuel flow valves comprising a low flow valve;a manually operated fuel flow valve for controlling an amount of fuel transferred to the at least two electronically operated fuel flow valves from the fuel source, wherein the manually operated fuel flow valve is coupled in parallel with at least one of the at least two electronically operated fuel flow valves;a user interface unit configured to receive a grill operation setting;at least one temperature sensor disposed adjacent to the cooking surface and configured to detect at least a grill operating temperature; anda control unit configured to: receive the grill operation setting from the user interface unit,receive the grill operating temperature from the at least one temperature sensor, andautomatically control the at least two electronically operated fuel flow valves for modulating the amount of fuel delivered to the at least one grill burner to maintain the grill operating temperature at a predetermined temperature based on the grill operation setting and the grill operating temperature by diverting a fuel flow downstream of the manually operated fuel flow valve through the high flow valve and diverting a fuel flow upstream of the manually operated fuel flow valve through the low flow valve. 2. The control system of claim 1, wherein the gas grill includes a plurality of grilling zones, the control unit being further configured to independently maintain the grill operating temperature at a respective predetermined temperature for each of the grilling zones. 3. The control system of claim 1, further comprising at least one food temperature probe configured to detect a food temperature of food being cooked on the gas grill, wherein the control unit is configured to receive the food temperature and present an indication of the food temperature through the user interface unit. 4. The control system of claim 1, wherein the control unit is further configured to: cause the at least one grill burner to operate at a maximum combustion rate when the grill operating temperature is below the predetermined temperature;cause the at least one grill burner to operate at a minimum combustion rate when the grill operating temperature is above the predetermined temperature; andstop a flow of fuel to the at least one grill burner when a flare-up condition is detected by the at least one temperature sensor. 5. The control system of claim 1, further comprising a transmitter connected to the control unit, and a portable receiver with a second user interface unit, the transmitter being configured to transmit grill operating information to the portable receiver for presentment on the second user interface unit. 6. The control system of claim 1, wherein the at least one grill burner comprises a hi-flow burner and a low-flow burner. 7. The control system of claim 1, wherein the user interface unit comprises one or more of analog and electronic control devices. 8. A method for controlling a gas grill having a plurality of grilling zones each having at least one burner and at least two electronically operated fuel flow valves configured in a parallel relationship, the method comprising: sensing a grill operating temperature of a respective grilling zone;determining a temperature difference between the grill operating temperature and a predetermined grill temperature set point; andautomatically modulating the at least one burner of the respective grilling zone by controlling the fuel flow through the at least two electronically operated fuel flow valves in response to the temperature difference by diverting the fuel flow through a high flow valve located downstream from a manual valve and diverting the fuel flow upstream of the manual valve through a low flow valve. 9. The method of claim 8, wherein the modulating step comprises: operating the at least one burner at a maximum combustion rate when the grill operating temperature is below the predetermined grill temperature set point;operating the at least one burner at a minimum combustion rate when the grill operating temperature is above the predetermined grill temperature set point; andstopping a flow of fuel to the at least one burner when a flare-up condition is detected. 10. The method of claim 8, wherein the grill operating temperature of each grilling zone is independently controlled to maintain the each grilling zone at a respective predetermined grill temperature set point. 11. The method of claim 8, further comprising transmitting grill operating information of the gas grill to a portable receiver. 12. The method of claim 8, further comprising presenting a status of food being cooked in the respective grilling zone through a user interface unit of the gas grill. 13.

The gas grill of claim 13, wherein the manually operated fuel flow valve is coupled in series with at least one electronically controlled valve. 15. The gas grill of claim 13, wherein the at least one burner of the respective one of the grilling zones comprises a hi-flow burner and a low-flow burner. 16. The gas grill of claim 13, further comprising at least one food temperature probe configured to detect a food temperature of food being cooked on the gas grill, wherein the control unit is configured to receive the food temperature and present an indication of the food temperature through the user interface unit. 17. The gas grill of claim 13, wherein the control unit is further configured to: cause the at least one burner of a respective grilling zone to operate at a maximum combustion rate when the respective operating temperature of the respective grilling zone is below a predetermined temperature set point;cause the at least one burner of the respective grilling zone to operate at a minimum combustion rate when the respective operating temperature of the respective grilling zone is above the predetermined temperature set point; andstop a flow of fuel to the at least one burner of the respective grilling zone when a flare-up condition is detected in the respective grilling zone by the respective temperature sensor. 18. The gas grill of claim 13, further comprising a portable receiver and a transmitter connected to the control unit and the portable receiver, the portable receiver having a second user interface unit, the transmitter being configured to transmit grill operating information to the portable receiver for presentment on the second user interface unit.
