Title: Controlling equipment for circulation type bath heater
Inventor: KOBAYASHI TOSHIHIRO
IPC: F24H1/10
Filed: 1993-05-06
Abstract: PURPOSE:To prevent corrosion of a copper pipe and a copper fin by calculating an allowable maximum flow rate on the basis of the temperature of water entering a forced circulation device and by keeping the temperature of circulating outflow water at a prescribed temperature or above by controlling a flow rate varying means on the basis of judgement of a flow rate property judging means. CONSTITUTION:A controller 35 measures the temperature of circulating water by a circulating inflow water temperature thermistor 26. When a flow rate measured by a flow sensor 33 is judged to be larger than a set flow rate according to a flow rate propriety judging program in the case when a bath is heated under the condition that the initial temperature of water is five degrees, the controller 35 reduced the number of revolutions of a pump 15 according to a flow rate varying program 48, on the basis of the above judgement, so as to reduce the flow rate of the water. Circulation and heating are continues, and when the flow rate becomes larger than the set flow rate, the number of revolutions of the pump 15 is increased. Thereby the temperature of circulating out-flow water can be kept at 40 degree or above quickly even when the temperature of the water is low. Accordingly, the temperature of outer walls of a copper pipe 28 and a fin 21 can be kept at least at the dew points temperature of a combustion exhaust gas, and therefore no water drop sticks on the outer walls of the copper pipe and the fin.

Title: Controlling device of water heater
Inventor: NAKANE SHINICHI
IPC: F23N1/08
Filed: 1981-08-20
Abstract: PURPOSE:To obtain hot water of a predetermined temperature at all times, to compensate for the heat capacity of a hot water storing device itself and to make it possible to supply the hot water in a desired quantity. CONSTITUTION:The signal from a detector 4 for detecting the temperature of hot water from a heat exchanger 2 is inputted to a temperature controler 3 and a water quantity controler 8 and  the difference between the signal from the detector 4 and the set temperature signal from a temperature setting device 5 is operated. Further, the signal from a total water quantity setting  device 9 is inputted to the water quantity controler 8. Thus, the maximum quantity of feed water Fwmax is supplied to the water heater at the time of using the heater and when the quantity of the feed water is reduced in proportion to the above mentioned temperature difference from the time when a constant temperature controling condition is reached and when the temperature difference goes higher than a predetermined value. Further, in case where the hot water is supplied to the hot water storage device, the hot water is kept at the set temperature TWR during the period from the starting of the use of the water heater to the time t2 prior to the arrival of the constant temperature controling condition, then at the set temperature TWR' which is higher by DELTATWR than TWR during the period from t2 to t3 by reducing the quantity of the feed water FW to FW2 and after the time t3 onward, it is kept at the set temperature TWR again by increasing the quantity of the feed water FW to FW3 to thereby compensate for the heat capacity of the hot water storage device.

Abstract: PURPOSE:To prevent the deterioration in a frequency characteristic by forming a channel width on the reset drain side of a reset electrode to be larger than a channel width on the floating diffusion layer side thereof. CONSTITUTION:A signal charge is transferred in the direction of an arrow 1 and sent to a floating diffusion layer 4 through transfer electrodes 21, 22 and an output electrode 3, and it is detected in said layer 4. The detected signal charge is sucked up into a reset drain 7.
