摘要： PROBLEM TO BE SOLVED: To provide a cookstove with a top plate cover superior in safety without intruding exhaust gas into the top plate cover with a simple structure.
SOLUTION: A cutout part 3 is arranged in a lower end part of the top plate cover 2, and is constituted so that an exhaust port 10 is opened in the atmosphere by positioning the cutout part 3 just above the exhaust port 10 when closing a cover as mentioned later. When starting combustion of a grill burner 9e, the exhaust gas is introduced to the exhaust port 10, and is released in the atmosphere by rising in the cutout part 3 arranged in a just above part of the exhaust port 10. Thus, even if the grill is burnt in a cover closing state by mistake, the top plate cover 2 is not heated by the exhaust gas.

摘要翻译：要解决的问题：提供一种具有安全优越的顶板盖的烹饪器具，而不会以简单的结构将排气侵入顶板盖中。解决方案：在顶板盖2的下端部设置有切口部3，通过将切口部3恰好位于排气口10的正上方而使排气口10在大气中开放，关闭后面提到的封面。当烧烤炉9e开始燃烧时，排气被引入到排气口10中，并且通过在布置在排气口10的正上方的切口部分3上升而在大气中释放。因此，即使格栅在盖关闭状态下被错误地燃烧，顶板盖2不被废气加热。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a washing hot water filling unit with a reverse flow prevention device capable of surely preventing reverse flow even if check valves fail, and a bath hot water-supply device.
SOLUTION: This washing hot water filling unit 10 is constituted such that the check valves 17 and 19 are installed in a clean water supply pipe 55. A revere flow prevention device 20 with an atmosphere opened valve 23 is installed on the clean water system side of the check valve. Since an automatic opening/closing valve 23 is opened to the atmosphere in a remaining hot water feeding mode for feeding remaining hot water from a bathtub 5 to a washing machine 3, when the check valves 17 and 19 fail, reversely flowing water can be drained through the valves.

摘要： PROBLEM TO BE SOLVED: To provide a control method for a heating system to prevent water in heating piping from rotting and piping from corrosion even when a bath is not used for a long period. SOLUTION: When it is detected by a water level sensor 5 that a bath 7 is brought into an empty state or a state near the empty state, a water supply valve 4 is opened and a pump is temporarily stopped. Water supplied from a water supply is made to flow as is through a water supply valve 4 or after being heated by a burner 2 and flows to heating piping 9 through a heating system hot water supply valve 8. Since a drainage valve 11 is opened and a heating system return valve 10 is closed, water is drained through the drainage valve 11. This constitution drains polluted water stagnating in heating piping 9 and cleans the interior of the heating piping 9. Thus, even when the bath 7 is not used for a long time, water in the heating piping 9 is prevented from rotting and prevents piping from corrosion.

摘要： PROBLEM TO BE SOLVED: To provide a bath hot water supplying apparatus to shorten a hot water filling time as much as possible. SOLUTION: A water flow amount is controlled to a maximum, and by simultaneously driving both a heat-exchanger 3a for hot water supply and a heat-exchanger 4a for reheating of bath tub water, hot water heated by the heat-exchanger 3a for hot water supply is introduced in the heat-exchanger 4a for reheating of bath tub water, where hot water is poured in a bath tub 2 from both the outgoing side 9b and the return side 9a of a reheating of bath tub water circuit 9b. Further, heating for adjusting temperature to a set temperature is carried out by controlling a combustion amount of a gas burner 3b on the hot water supply unit 3 side or a combustion amount of a gas burner 4b on the reheating of bath tub water unit 4 side. As a result, pouring of a large capacity of hot water is practicable and a hot water filling time is shortened by an amount equivalent to the increase of the capacity.

摘要： PROBLEM TO BE SOLVED: To detect quickly an out-of-over temperature-detecting means out of three or more temperature detecting means by comparing temperature information outputted from the individual temperature detecting means and by judging one temperature detecting means as failing when a difference of the temperature information thereof from that outputted from other temperature detecting means exceeds a prescribed value. SOLUTION: A temperature sensor S1 detects the temperature of water entering hot water supply equipment 1 and a temperature sensor S2 detects the temperature of the water after it is heated by a heat exchanger 16, while a temperature sensor S3 detects the temperature of hot supply water after the hot water obtained by the heat exchanger 16 is mixed with water from a bypass passage 8. Water is made to flow through a water pipe 6 and output values of the temperature sensors S1-S3 are compared in the same temperature condition in a state wherein combustion of gas is not conducted. When a failure occurs in a system of any temperature sensor, the failing temperature sensor alone outputs an abnormal value different from ones of other temperature sensors and sends it to CPU 22a and, therefore, the temperature sensor failing can be detected. Accordingly, it is possible to shorten a time for a repair operation and to improve operability.

摘要： PURPOSE: To return data from other device even when data peculiar to a device is temporarily lost by providing a refugee information storing means in a peripheral device capable of communicating with a gas device having an inherent information storing means and transferring inherent information to the refuge information storing means for every constant time. CONSTITUTION: A gas meter 2 and a gas device 3 send and receive data through a communication line 5. The gas meter 3 and a remote controller 4 send and receive data through a communication line 6. Data which must be held in respective devices is retracted to the EEPROM 22 of the gas meter 2, the EEPROM 32 of the gas device 3 and the EEPROM 42 of the remote controller one another and the data is updated to the latest one for every constant time. Thus, even when the trouble of the gas device or other peripheral devices is generated, and therefore, the data held by the EEPROM until that time is lost due to the change of an electrical base, the safety of the data can be insured, since the data is held by other devices.

摘要： PURPOSE: To provide a gas system capable of directly supplying gas without controlling gas components having respectively different calorific values. CONSTITUTION: A gas meter 4 and a gas instrument 2 are connected to a gas pipe and gas is supplied to the instrument 2 through the pipe. The meter 4 can change a conversion rate for the flow rate of an integration memory. The instrument 2 can measure the combustion calorific value of the gas and a command center 6 can calculate the calorific value of supplied gas per unit volume from the conbustion calorific value and the flow rate of gas used. In the case of importing and supplying natural gas components having respectively different calorific values also, the calorific value of supplied gas per unit volume is computed by the gas instrument 2 or the like and the conversion rate of the meter 4 or the idle fuel rate of the instrument 2 can be changed based upon the calorific value of supplied gas, so that gas components can be supplied without controlling them and the cost of gas supply can be reduced.

摘要： PURPOSE: To achieve a troubleshooting of a gas apparatus by starting an operation procedure for trouble shooting by a command from the side of a troubleshooting device to diagnose operating condition of actuators. CONSTITUTION: A troubleshooting device 1 is connected to a gas apparatus 11 to start. A CPU 2 works a CPU 12 of the gas apparatus 11 to read out an error code and a trouble history preserved in an EEPROM 15. Then, the CPU 2 outputs an error code in the normal sequence operation of the gas apparatus 11 when the CPU 12 itself detects the abnormality of the gas apparatus 11. Operation modes M1 -Mp for troubleshooting stored in an ROM 14 are called up properly in response to each error code to judge a trouble system. In the judging of the trouble system, a current value and a voltage value at a specified part in the gas apparatus 11 are detected to perform an arithmetic processing according to a troubleshooting program by the CPU 2. The results of diagnosis or parts troubled are shown on a display section 3.
