JPH0611184A - Hot-water supplier equipped with bath boiler - Google Patents

Abstract

PURPOSE:To provide a hot-water supplier equipped with a bath boiler, in which inconvenience in handling of the same is eliminated, by a method wherein hot-water supplying function is not stopped even when abnormality related to the function of the bath boiler is generated to permit the use of the hot-water supplying function as it is, in the abnormal stopping of the hot-water supplier equipped with a bath boiler. CONSTITUTION:The title device is provided with a detecting circuit 18, detecting the faulty parts or the abnormal operation of instrument of a hot-water supplier equipped with a bath boiler, and a stopping circuit 19, stopping the operation of the instruments when the detecting circuit 18 has detected abnormality. When faulty parts or abnormal operation of instruments related to hot-water supplying function has been detected, all of operations are stopped and the abnormality is indicated but when the faulty parts or the abnormal operation of instruments related to the function of the bath boiler has been detected, only the function of bath boiler is stopped and a controller 11 indicates the abnormality indication, discriminated from the stopping of all operations, while hot-water can be supplied as it is.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater with a bathtub having an abnormality display function.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional water heater with a furrow has a detection circuit 40 for detecting defective parts of the equipment and an abnormality of the equipment, and the operation of the equipment when the detection circuit 40 detects an abnormality. And a stop circuit 41 for stopping the
Is activated, all the operations of the equipment are stopped, and an error is displayed on the remote controller 42.

In the above operation, whether the defective parts or the abnormality of the equipment is related to the hot water supply function or the roof function, all the operations of the equipment are stopped and the abnormality is recognized regardless of which failure. indicate.

[0004]

However, in the above-mentioned conventional configuration, when an abnormality related to the furrower function occurs and the hot water supply function is in a normal state, the hot water supply function is stopped, and even in the kitchen or when using the bath by dropping it. There was a problem that it became impossible and inconvenience occurred.

The present invention has been made to solve the above-mentioned problems, and is intended to eliminate inconvenience in use because the hot water supply function can be used as it is without stopping the hot water supply function even if an abnormality relating to the furrower function occurs. is there.

[0006]

In order to achieve the above-mentioned object, the present invention comprises a detection circuit for detecting a defective part or an abnormality of a device, and a stop circuit for stopping the operation of the device when the detection circuit detects an abnormality. , Equipped with a controller, when this controller detects defective parts related to the hot water supply function or equipment abnormalities, it stops all operations of the equipment and displays the abnormality, and detects defective parts related to the furogama function or equipment abnormalities. At this time, only the function of the furogama is stopped, and an anomaly is displayed separately from when the hot water supply function is stopped.

[0007]

According to the present invention, the hot water supply function does not stop even if an abnormality relating to the frothing function occurs due to the above-mentioned configuration. Moreover, the abnormality can be distinguished by the display.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a water heater with a fryer according to the present invention will be described below with reference to FIG.

Reference numeral 1 denotes a hot water heat exchanger, which is constructed integrally with a bath heat exchanger 6. By opening the hot-water tap 2 that extends to the hot-water supply water circuit of the hot-water supply heat exchanger 1, water is supplied to the hot-water supply heat exchanger 1 by tap water pressure. The flow rate sensor 3 provided in the hot water supply / pumping circuit detects the amount of water passing through the heating burner 4, causing the heating burner 4 to burn. . A bath heat exchanger 6 is connected to the bath 9 by a circulation pipe 8 via a circulation pump 7 for circulating the water in the bath 9. By operating the combustion operation of the heating burner 4 and the circulation pump 7, the water in the bath 9 is circulated and heated. When the set hot water temperature is reached, the operation is stopped by the detection of the bath thermistor 10 provided on the outflow pipe of the circulation pipe 8. Reference numeral 11 is a controller having a detection circuit 18 and a stop circuit 19, and in addition to the controller 11, the remote controller for kitchen 1 having the function of the controller is also provided.
2 and a remote controller 13 for the bath. Reference numeral 14 is an operation switch, 15 is an operation lamp, 16 is a bath operation switch, and 17 is a bath operation lamp.

In the above structure, the operation when a defective part occurs will be described with reference to FIG. If, for example, the hot water supply thermistor 5 becomes defective during the hot water supply operation, such as a disconnection, the detection circuit 18 provided in the controller 11 detects an abnormality and stops the heating burner 4 and the circulation pump 7 as shown in FIG. 2 '(a). Then, after all the driving operations are stopped by the stop circuit 19, the operation lamp 15 provided in the kitchen remote controller 12 blinks. On the other hand, for example, when the bath thermistor 10, which is a component in which only the function of the fryer is defective, becomes defective such as disconnection, the detection circuit 18 provided in the controller 11 detects the abnormality and the circulation pump 7 as shown in FIG. 1B. After stopping the operation, the only operation of the bath cover function is stopped, and then the bath operation lamp 17 provided in the bath remote controller 13 blinks.

Above, the hot water supply thermistor 5 and the bath thermistor 1
Although the example of the component defect of 0 has been described, in the case of other component defects, the blinking pattern of the operation lamp 15 or the bath operation lamp 17 is changed and the content of the defect is subdivided and displayed.

FIG. 3 shows another embodiment relating to the abnormality display. 20 is a remote controller for the kitchen, 21 is an operation switch, 2
2 is a hot water supply display unit, 23 is a bath display unit, and 24 is an abnormality display unit. When a component having a defect in the hot water supply function becomes defective during operation, a defect content code is displayed on the abnormality display unit 24, and the hot water supply display unit 22 and the bath display unit 23 are turned off.
When a component in which only the fryer has a malfunction becomes defective, a malfunction content code is displayed on the malfunction display unit 24, and the hot water supply display unit 22 remains lit and the bath display unit 23 goes off.

[0013]

As described above, in the water heater with a flat screen according to the present invention, when a defective component or a device abnormality relating to the hot water supply function is detected, the entire operation of the device is stopped and an error is displayed to indicate the function of the flat glass. When a defective part or equipment abnormality related to is detected, only the roof function is stopped, and the abnormality is displayed separately from the hot water supply stop. It does not stop, and you can use hot water in the kitchen or take a bath by dropping it. In addition, it is possible to provide a highly practical hot water heater with a bathtub, which makes it possible to clarify the usable functions by displaying the distinguished abnormalities and eliminates the inconvenience in use.
