Abstract

PURPOSE:To prevent occurrence of an incomplete combustion or a vibratory combustion in a hot water feeding device by a method wherein in the case that an amount of combustion for hot water feeding operation is increased during a simultaneous hot water feeding and heating of a bath, an amount of air corresponding to the increased amount of combustion is supplied and then fuel for hot water feeding device is increased and supplied with a delay of specified time. CONSTITUTION:In the case that a combustion amount of a hot water feeder 1 is increased during a simultaneous combustion of a hot water feeder 1 and a bath furnace 2, an operation controlling device 12 may increase an amount of combustion air to an amount corresponding to an increased amount of combustion by an air feeding fan 6, the thereafter fuel in the hot water feeder 1 delayed for a specified period of time is increased and supplied by an increased amount. With such an operating sequence as above, in the case that an amount of combustion in the hot water feeder 1 is increased during simultaneous combustion of hot water feeding and heating a bath, hot water feeding combustion gas and the bath combustion gas are discharged through a common discharging pipe 5, resulting in that a lack of combustion air during an increasing transient period of an amount of combustion in the hot water feeder caused by increased discharging resistance is eliminated and at the same time an incomplete combustion and vibratory combustion in the hot water feeder 1 can be prevented from being produced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an operating mode of a hot water bath apparatus.

BACKGROUND OF THE INVENTION Conventionally, this type of hot water bath equipment has been constructed as shown in Fig. 3.
When the amount of hot water burned increased, combustion air and fuel were simultaneously increased to correspond to the increased amount of hot water burned.

Problems to be Solved by the Invention However, in the above operation, if the amount of water heater combustion is increased during simultaneous combustion in the hot water bath, the exhaust resistance increases due to the common exhaust pipe, resulting in insufficient combustion air for the water heater, resulting in incomplete combustion. This had the problem of generating combustion and oscillating combustion.

Means for Solving the Problem In order to solve the above problem, when increasing the amount of hot water combustion during hot water bath simultaneous combustion, after supplying an amount of air corresponding to the increased amount as combustion air on the hot water heating side, The fuel for the water heater is supplied by the increased amount after a time delay.

Function: This configuration eliminates the lack of combustion air in the water heater that occurs when the water heater combustion amount is increased during simultaneous combustion in the hot water bath, and eliminates the occurrence of incomplete combustion and oscillating combustion in the water heater. can.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, a water heater 1 and a bath kettle 2 are installed side by side, and an exhaust port 3 of the water heater 1 and an exhaust port 4 of the bath kettle 2 are joined by a common exhaust pipe 5 and exhausted.

In addition, 6.7.8 describes the air supply fan, burner,
It is a heat exchanger, and 9, 10, and 11 are an air supply fan, a burner, and a heat exchanger for the bathtub 2. Reference numeral 12 denotes an operation control device that controls the operation of the water heater 1 and the bathtub 2.

FIG. 2 shows the operation operation of the operation control device 12.
In the above configuration, when the combustion amount of the water heater 1 is increased while the water heater 1 and the bath pot 2 are burning simultaneously, the air supply fan 6 increases the empty amount for combustion to an amount corresponding to the increased amount of combustion. After that, after a certain period of time delay, the burner 7 supplies more fuel to the water heater 1 by the increased amount.

If the combustion amount of the water heater 1 is increased during the simultaneous combustion of the hot water supply bath and the hot water bath due to the above configuration operation sequence, the exhaust resistance will increase because the hot water supply combustion exhaust gas and the bath combustion exhaust gas are exhausted from the common exhaust pipe 5. This eliminates the lack of combustion air during the transition period when the amount of combustion in the water heater increases, and eliminates the occurrence of incomplete combustion and oscillating combustion in the water heater.

Effects of the Invention As described above, according to the present invention, in a hot water bath apparatus having two combustion parts, a water heater and a bath pot, that share a common exhaust pipe, when the amount of water heater combustion is increased during simultaneous combustion of the hot water bath, The lack of combustion air during the transition period when the amount of water heater combustion increases is resolved.
It has the effect of preventing incomplete combustion and vibrational combustion in water heaters.
