Abstract: PURPOSE:To enable an input to be changed with the oscillation frequency of an inverter circuit maintained constant as well as to eliminate the occurrence of interference sound even when plural numbers of inverters are simultaneously operated by changing the ratio of the conducting period between two switching elements with the sum of the conducting period left constant. CONSTITUTION:A variable conduction ratio setting section 9g connected with an oscillator 9f oscillating a constant oscillation frequency allows a comparator section 9c to compare an input set value set in an input setting section 9a with an actual input detected by an input detecting section 9b so that a conduction ratio between No.1 switching element 3 and No.2 switching element 4 is changed depending on outputted error voltage (e). An input electric power return loop as set forth herein above allows the conduction ratio between No.1 switching element 3 and No.2 switching element 4 to be controlled in such a way that the actual input is equal to the input set value. By this constitution, the input can be changed with the oscillation frequency maintained identical, and heating can thereby be processed without the occurrence of interference sound even when plural numbers of inverter circuits are operated.

Title: Setting method for learning initial water flow rate at water flow control valve in hot-water apparatus
Inventor: ONODERA SHUICHI
IPC: F24H1/10
Filed: 1993-03-22
Abstract: PURPOSE:To make it possible to perform learning-setting of degree of throttling of a water flow control valve of a hot-water apparatus in such a manner that an undershoot and overshoot of hot-water temperature at the redelivery of hot-water does not occur even if feed water pressure changes. CONSTITUTION:A rise water flow rate at the delivery of hot-water is sensed by means of a signal from a flow rate sensor 9 so that, at a water flow rate comparing unit 26, the rise water flow rate is compared with a desired water flow rate having been store in the unit 26 (rise water flow rate which makes smaller an undershoot or overshoot of hot-water temperature). Based on this comparison, at a water flow rate control valve throttling time set element 27, a corrected throttling time, which is obtained by adding a small unit time to or subtracting it from the throttling time of a water flow rate control valve 16, is stored in a data storing element 31 so that a rise water flow rate at the following delivery of hot-water approaches a desired water flow rate. When a hot-water tap is closed, on receipt of a command from a water flow control valve drive element 29, the valve 16 is placed in a state wherein the valve 16 is throttled from a fully opened position to a state throttled by an amount corresponding to the corrected throttling time, whereby the valve 16 is put on stand-by to be prepared for the following redelivery of hot-water. The rise water flow rate at the redelivery of hot-water approaches the desired water flow rate, and hence undershoot or overshoot becomes smaller.
