Abstract

PROBLEM TO BE SOLVED: To provide combustion equipment which can prevent its temperature stability from getting worse due to change in atmospheric temperature when the equipment restarts the delivery of hot water after stopping combustion. SOLUTION: Upon detecting the closure of a hot water tap, this combustion equipment stops combustion by stopping oil flow in the oil passage of a hot water supplier. Though the equipment starts a blower for hastening the igniting speed when the equipment is ignited next simultaneously with the combustion stoppage, the equipment controls the number of revolutions or/and rotating duration of the blower based on the temperature detected by means of an atmospheric temperature thermistor.

2. Description of the Related Art Conventionally, in a combustion apparatus such as a water heater, as a method of supplying hot water having a stable temperature at the time of re-ignition after stopping combustion, hot water in a heat exchanger is supplied at a temperature higher than a set temperature of equipment. And a method of supplying hot water at a stable temperature by mixing with hot water. In addition, if the speed of the ignition is not increased, the water supplied to the equipment flows into the heat exchanger. Therefore, the blower is operated for a certain period of time to prepare for the next ignition. However, if the operation time of the blower becomes longer, the hot water in the heat exchanger is cooled, so that the temperature of the hot water in the heat exchanger becomes lower than the set temperature of the equipment. Can not supply hot water. The time to operate the blower is determined from the balance between these two.

However, in the conventional combustion apparatus, in order to supply hot water at a stable temperature at the time of ignition,
The temperature of the hot water in the heat exchanger must be at least higher than the set temperature of the equipment. However, the actual outside temperature varies from low to high, so the temperature at which the heat is cooled by the heat exchanger is not constant. Therefore, if the number of rotations and the rotation continuation time of the blower immediately after combustion stop are fixed, it is not possible to cope with various air temperatures.

In order to achieve the above object, a combustion apparatus comprising at least a heat exchanger, a blower for sending combustion air, and a temperature thermistor for detecting air temperature is provided. Since the number of revolutions and / or the duration of rotation of the blower after the combustion is stopped is controlled by the detected value of the temperature thermistor immediately after the combustion is stopped, the temperature stability at the time of re-starting the hot water after the combustion is stopped is determined by the temperature. It does not get worse.

When the detected value of the temperature thermistor immediately after the combustion is stopped is lower than a predetermined value, the rotation speed of the blower after the combustion of the combustion device is stopped is reduced and the rotation continuation time is lengthened. To reduce the rotation speed of the blower,
This is because the temperature of the heat exchanger is low because the outside air temperature is low, so that the temperature is prevented from rapidly dropping. The reason why the rotation continuation time of the blower is increased is to increase the ignition speed at the time of re-starting hot water after stopping the combustion because the outside air temperature is low. The rotation continuation time at that time is arbitrarily set so that the temperature of the heat exchanger becomes low and does not affect the time of tapping.
