Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to reheating operation, which is a different mode from automatic operation of an automatic hot water bath apparatus.

BACKGROUND ART Conventionally, as shown in FIG. 3, this type of automatic hot water supply bath apparatus starts a combustion sequence by turning on a reheating switch, regardless of the presence or absence of a bathtub. (Utility Model Application No. 60-10156) Problems to be Solved by the Invention However, in the above-described operation, even when there is no water in the bathtub, combustion in the bathtub is started by turning on the reheating switch. This had the problem of causing fire.

Means for solving the problem In order to solve the above problem, a water level sensor is installed to detect a predetermined water level at which the bathtub does not run dry, and when the water level in the bathtub is lower than the predetermined water level, an instantaneous water heater is installed. After pouring hot water at a preset temperature to a predetermined water level, reheating is started, and when the water level is higher than the predetermined water level, reheating is started as in the conventional method.

Function: With this configuration, it is possible to automatically pour hot water and obtain a predetermined water level and temperature without causing a dry firing accident when reheating.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, the hot water outlet pipe 2 of the instantaneous water heater 1 is
It is branched into a tap 3 having a tap 3 and a tap 5 having a pouring valve 4, with the tap 5 facing a hopper 6. The pouring pipe 7 has a hopper 6 above,
The lower part communicates with the inlet water can part 8 of the bath heater, and the bathtub 9 communicates with an upper circulation pipe 10, an inlet water can part 8, a heat transfer tube 11, an outlet water can part 12, and a lower circulation pipe 13 in this order. There is. Further, a water level sensor 14 and a temperature detection sensor 15 are provided in the outlet water can section 12 , and a circulation pump 16 is provided in such a manner that it has an inlet 17 in the heat transfer tube 11 and a discharge port 18 in the upper circulation pipe 10 . . In addition, 19 is a control box,
20 is a bath remote control for the bathroom, 21 is a main remote control for the kitchen, 22 is an automatic operation switch, and 23 is a reheat switch.

In the above configuration, when the automatic operation switch 21 is turned on, the hot water pouring valve 4 opens, and hot water from the instantaneous water heater 1 passes through the hot water tap 2, hot water pouring valve 4, hot water tap 5, and enters the hopper 6. The water is dropped into the bath heater inlet water can part 8 through the pouring pipe 7, and the heat transfer pipe 11.
Molten metal is poured into the melt tank 9 through the outlet water can section 12 and the lower circulation pipe 13. The water level in the bathtub 9 is measured by a water level sensor 14, and when the water level reaches a preset level using the main remote control 21, the pouring valve 4 is closed and the pump 1 is turned on.
6 is operated to circulate the water in the bathtub into the bath pot, and the temperature detection sensor 15 determines whether the temperature in the bathtub has reached the set temperature, and if it is insufficient, starts reheating. Boiling is completed when the set temperature is reached.

Next, when the reheating switch 23 is turned on, the water level in the bathtub 9 is detected by the water level sensor 14, as shown in FIG. If the temperature is below the minimum level, hot water of the same temperature as the set temperature during automatic operation is poured from the instantaneous water heater 1 to the lowest level in the same way as during automatic operation, and then reheating is started. Additionally, if you turn off the reheat switch, reheating will stop.

By using the reheating sequence as described above, even if you accidentally turn on the reheating switch when there is no water in the bathtub, you can prevent the bathtub from running dry.
Since hot water at the same temperature as the set temperature during automatic operation is poured to a water level at which reheating can be started, the time required for reheating can be shortened.

Effects of the Invention As described above, according to the present invention, in an automatic hot water bath pot having an automatic operation switch and a reheating switch, when the reheating switch is turned on, the water level in the bathtub is set to a predetermined level that prevents the bathtub from becoming empty. If the water level is below the water level, reheating will begin after pouring hot water to a predetermined water level, so even if you accidentally turn on the reheating switch, dry heating can be prevented, and hot water will be poured from the instantaneous water heater. This has the effect of shortening the prescribed time for additional firing.
