摘要： PROBLEM TO BE SOLVED: To prevent lowering of a hot water temperature during reuse and to perform the immediate use of hot water having a given temperature by a method wherein a drive means is operated such that a water temperature in a heat-exchanger detected by a heat-exchange thermistor exceeds temperature corresponding to temperature set by a user. SOLUTION: When a switch 17 serving as an operation device is in an OFF-state, an apparatus holds the state of an operation stand-by state and when the switch is in an ON-state, water temperature in a heat-exchanger is detected by a heat- exchange thermistor 14. When a water temperature in the heat-exchanger is reduced to a value lower than a decision value stored at an ROM part 24 of a microcomputer 20, a drive means 15 of a heat generating device is brought into an ON-state, and a burner is caused to effect combustion. Further, when the water temperature is increased to a value higher than the decision value stored at the ROM par 24, combustion of the burner is stopped and the drive means 15 of the heat generating device is turned OFF, and the hot water temperature of a heat-exchanger 3 is kept at a set value to prepare for reuse. This constitution prevents lowering of a water temperature in the heat-exchanger and immediately feeds hot water having temperature set by a user.

摘要： PURPOSE:To reduce a cost, to reduce a space, and to enable reliable bleeding of air by providing a 3-way valve which is selectively connected to an outbound pipe to an inbound pipe or a hot water feed pipe and switches a device to a circulation mode or a hot water feed mode and a control means to temporarily switch the device to the circulation mode during feed mode operation. CONSTITUTION:An outbound pipe 11 and a hot water feed pipe 6 are brought into a connection state by a 3-way valve 17 to selectively connect the outbound pipe 11 to an inbound pipe 12 or the hot water feed pipe 6 to bring a device into a hot water feed mode, and hot water in a hot water feed source 4 is fed in the hot water feed mode to a bath tub 2. Meanwhile, the outbound pipe 11 and the inbound pipe 12 are brought into a connection state by the 3-way valve 17 to bring the device into a circulation mode, and hot water in the bath tub 2 is circulated to effect heating and heat insulation by means of a heat exchanger 10. As noted above, since the circulation mode and a hot water feed mode are switched from each other through the single 3-way valve, a cost and a space can be reduced. A control means 18 inputs signals from a pressure sensor 13 and a temperature sensor 15 to compare the signals with respective set values for decision, controls the hot water feed source 4, a pump 9, the heat exchanger 10, and the 3-way valve 17 through the working of a processor, and controls bleeding air residing in the inbound pipe in a way to temporarily switch the hot water feed mode to the circulation mode during hot water feed mode operation.

摘要： PURPOSE:To prevent disconnection of lead wires and coaxial lines by detaining a sound transmission tube as an antenna on a printed circuit board in a main housing and bringing this tube into contact with a conductive flat spring connected to the circuit of the board slidably. CONSTITUTION:A microphone 10 for transmission is provided in a main housing 1, and a transmitter 21 is provided in an open/close arm 6 freely openably and closable coupled to the main housing 1, and a metallic sound transmission tube 22 is provided which has one end fixed to the transmitter 21 and has the other freely turnably fitted to the microphone 10 for transmission. This sound transmission tube 22 is detained on a printed board 13 in the main housing 1 as the antenna and is brought into contact with a conductive flat spring 23 connected to the circuit of this board slidably. Consequently, a torsional force does not act upon the sound transmission tube because of slidable contact between the sound transmission tube 22 and the microphone 10 for transmission and between the sound transmission tube 22 and the conductive flat spring 23 through the open/close arm 6 is turned. Thus, the disconnection due to torsion accompanied with opening and closing of the open/close arm is prevented.
