Abstract

PURPOSE:To simplify the application to a bath apparatus, in a method for detecting the leakage of the drain cock of a bathtub especially during a period waiting for the supply of water in an automatic bath apparatus, by detecting the defective closure of the drain cock in the bathtub without directly judging the closed state of the drain cock. CONSTITUTION:At the point of time when the water level in a bathtub B falls by a definite level from a set water level, a water supply function part 1 is operated to supply a predetermined amount of hot water or water to the bathtub B and the water level in the bathtub B is held to a set water level. In this bath apparatus, a water level monitor apparatus 2 monitoring the water level in the bathtub B is provided to judge the leakage of a drain cock generated when the change of the output from the water level monitor apparatus 2 corresponding to the falling of a water level is continued for a definite time or when said change of output is detected every definite number of detection operations or when the output water level falls to a judgement standard level or less.

[Prior art and its problems] In recent bath equipment, a so-called water replenishment device is used to maintain the water level in the bathtub at the set water level by supplying the insufficient amount of hot water when the water level in the bathtub has fallen below the set water level. Equipped. Therefore, when the bath device is set to automatic operation, the water level in the bathtub is always maintained at the set water level. Since these water replenishment operations proceed automatically, these operations will continue even when no one is bathing.If the drain valve in the bathtub is not fully closed, the wasteful water replenishment operation will continue. A situation arises. Therefore, in order to prevent such a situation, the inventor monitors the closed state of the drain plug in the bathtub, controls the water replenishment operation based on the monitoring result, and thereby prevents the above-mentioned wasteful water replenishment operation. I planned something. This requires a device to detect leaks from drain plugs.
It is necessary to incorporate this device into the water replenishment device of the bath equipment.

In this control program, when hot water filling starts, the hot water filling valve (35) is opened and the hot water filling circuit (34) is opened.
The bathtub (B) is filled with hot water through the . This hot water filling start time (T1) is stored and the hot water filling operation proceeds. If the hot water filling operation is completed within the set time (T2), it is determined that the hot water filling is due to normal operation.If the hot water filling operation takes longer than necessary, in other words, the hot water filling time is When the time exceeds the set time (T2), it is determined that there is a leak in the drain valve, and the hot water filling valve (35) is closed.
is closed and the alarm buzzer (N) is activated. When hot water filling progresses normally and the water level in the bathtub (B) reaches the set water level (H0), the hot water filling valve (35) is closed at this time as well, and from then on, water replenishment and drain plug leakage monitoring status is entered. .

In this embodiment, the degree of decrease in the water level in the bathtub (B) is detected at the same time intervals as in the first embodiment, and
If the degree of water level decrease above a certain level continues three times, it is determined that there is a leak in the drain valve, and the hot water filling valve (35) and alarm buzzer (N) are activated. If the degree of water level decrease is within a certain level, the detected pressure (P) is compared with the refilling start water level (H1), and if the detected pressure (P) is higher than the refilling start water level (H1), refilling is started. and drain valve leak monitoring status. Then, the detection pressure (
When P) becomes lower than the water replenishment start water level (H1), the process moves to the next step, where the detected pressure (P) and the judgment reference water level (H2
) are compared. Then, when the detected pressure (P) is higher than the determination reference water level (H2), water replenishment operation is performed. Water is replenished to the set water level (H0) by an operation similar to the hot water filling operation. Conversely, the detected pressure (P) is the judgment reference water level (H
If it is lower than 2), it is determined that there is a leak in the drain plug and the alarm buzzer (N) is activated. In addition, instead of activating this warning buzzer, when it is determined that there is a leak in the drain plug (V), it is also possible to bring the appliance into a stopped state or to stop fully automatic operation. Furthermore, the water pressure gauge as the water level monitoring device (2) can be used in a circulating heating circuit (33) in addition to the method of directly detecting the water pressure in the bathtub as in the above embodiment.
The heating circuit may be connected to the circulating heating circuit to detect the pressure inside the bathtub via the heating circuit.
