Field of the Invention The present invention relates to a forced-circulation bath kettle having a hot water filling function, which has an automatic hot water filling function for a bathtub and stops boiling of hot water at a preset temperature.

と、追焚運転を停止する制御手段を有している。2. Description of the Related Art A forced-circulation bath kettle is reheated in the middle of a reheating circuit (in the course of returning hot water from the bathtub to the bathtub) during a reheating operation for raising the temperature of hot water in the bathtub. A control means is provided which has a built-in temperature sensor and stops the additional heating operation when the bather determines that the hot water has been heated to the preset hot water temperature by the output from the additional heating temperature sensor.

てしまう。[0003] The reheating temperature sensor generally has a negative characteristic with respect to temperature such that the resistance value is large when the detection temperature is low, and the resistance value is low when the detection temperature is high. In the unlikely event that the additional heating temperature sensor causes a disconnection failure, the resistance value shows a maximum value and the detection temperature becomes lower than the actual temperature, and if a short circuit failure occurs, the resistance value shows a minimum value and the detection temperature decreases. The temperature will be higher than the actual temperature.

Even if the actual hot water temperature becomes higher than the set temperature, reheating will be continued without terminating the reheating, and if a short circuit fault occurs,
The reheating will end even though the actual hot water temperature is lower than the set temperature.

Disconnection detection and short-circuit detection are performed for the failure of the reheating temperature sensor, and when abnormal, the operation of the bath kettle is stopped, the failure of the reheating temperature sensor is notified to the user, and the safety To ensure that.

る。In the method for detecting disconnection or short-circuit, a signal from a reheating temperature sensor, for example, a reheating temperature sensor is usually used if the reheating temperature sensor is a resistor having a negative characteristic with respect to temperature. The determination is made based on whether the temperature is outside the range of the temperature environment and the signal of the reheating temperature sensor exceeds or falls below a specific level. More specifically, the temperature range to be detected in use is 0. Since it is about 60 ° C. to 60 ° C., the detection is performed by setting the disconnection failure detection level to −20 ° C. and the short-circuit failure detection level to 70 ° C. as levels outside of this range.

For example, the contact resistance at the contact portion between the additional heating temperature sensor itself and the lead wire for transmitting the signal to the control board in the bath can be increased due to corrosion or poor soldering. If a serious failure occurs, it cannot be detected by the conventional disconnection detection because it is not a complete disconnection, and the resistance value of the reheating temperature sensor has actually increased from the normal state. There is a problem that a lower hot water temperature is detected.

Is detected at the time of hot water supply operation to the bathtub 3, and when a temperature difference between the detected temperature of the hot water supply temperature sensor 1 and the detection temperature of the additional heating temperature sensor 6 exceeds a predetermined value occurs during the hot water supply to the bathtub 3, the bath The operation of the shuttle is stopped. this is,
By making the hot water supplied to the bathtub 3 pass through the two sensors, the difference in the detected temperature between the failed sensor and the non-failed sensor is utilized. still,
The difference in the detected temperature here depends on the accuracy of the sensor itself, but it is preferable to determine that a failure has occurred when a detected temperature difference of about 1 ° C. to 3 ° C. occurs.

The measurement is preferably performed after a lapse of time (about 3 to 5 minutes), and the failure detection accuracy can be improved by comparing the average values of the detection values of a plurality of detections, not one detection.
