水する機構を設けない限りカバーできない。In the conventional automatic bath apparatus, the required hot water supply amount is calculated based on the bathtub cross-sectional area coefficient. Therefore, when the bathtub cross-sectional area coefficient varies, the water level after hot water supply varies. If the water level is lower than the target set water level, it can be covered by supplying hot water again. However, when the water level exceeds the set water level, it cannot be covered unless a mechanism for automatically draining water from the bathtub is provided.

際の動作を説明する。The operation of the above configuration will be described. The user sets a desired water level using the operation unit 3 and uses the water level. Since the set water level is represented by the height from the hot water supply port 8, the required hot water supply amount to the set water level differs depending on the capacity and shape of the bathtub 9 even at the same set water level. Therefore, the amount of hot water supply per cross-sectional area of the bathtub 9, that is, the bathtub cross-sectional area coefficient is determined during the first operation in which the equipment is installed. Hereinafter, the operation for determining the coefficient will be described.

となる。When the operation is started, the control unit 5 first performs an operation for submerging the hot water supply port 8. Since the hot water supply port 8 is usually installed at a height of 10 to 20 cm from the bottom of the bathtub, about 50 liters of hot water is supplied to the vicinity of the hot water at a time. Assuming a hot water supply flow rate of 10 liters per minute,
To supply 50 liters of water, you need to supply water for 5 minutes. Therefore, hot water supply unit 1 is driven and hot water is supplied into bathtub 9 until hot water supply amount detection unit 4 measures 5 minutes. The water level detection unit 2 is constituted by a pressure sensor, and detects the water level in the bathtub 9 by detecting the pressure in the hot water supply path when the hot water supply is stopped. Even if hot water is supplied in a range where water is not supplied to hot water supply port 8, no change occurs in the water level value detected by water level detecting section 2. Therefore, if you look at the water level after a small amount of hot water has changed,
It can be recognized that the water level has risen to the hot water supply port 8. Therefore, after the hot water is supplied for one minute (equivalent to 10 liters), the operation of checking the water level is repeated. When it is detected that the water level has risen to the hot water supply port 8, the hot water supply is performed for 3 minutes (equivalent to 30 liters) in order to completely submerge the opening of the hot water supply port 8. The water level after hot water supply is h0. Next, hot water is supplied from this water level for 4 minutes (equivalent to 40 liters), and the water level after the hot water supply is defined as h1. By calculating the ratio between the amount of hot water supplied and the raised water level, the bathtub sectional area coefficient K can be obtained. K = 40 / (h1-h0)

できる。Next, in order to fill the water from the water level h1 to the set water level hS, a required hot water amount W1 up to the set water level hS is obtained. W1 = K × (hS−h1), where K,
hS and h1 each include a detection error of the water level detection unit 2. Therefore, W1 also includes variations, and even when the amount of hot water changes during hot water supply, the water level after hot water supply also becomes a factor that varies with hS. If the water level is lower than hS, the required hot water supply amount up to hS may be calculated again and hot water may be supplied. However, if the water level is higher than hS, the water cannot be drained. No. Since the error increases in proportion to the amount of hot water supply, the correcting unit 7 is used to limit the error on the side exceeding the set water level.
Is corrected to the required hot water amount W1 calculated by the following. If the required hot water amount W1 exceeds 50 liters, the required hot water amount W1 is set to 0.1.
Supply 9 times the amount of hot water. If the amount of hot water is less than 50 liters, the error is small and no correction is made. By the above operation, the hot water can be filled to the set water level. As a method of correction, a method of subtracting 10 liters from the required hot water amount W1 or a simple method of multiplying and storing the bathtub cross-sectional area coefficient K by 0.9 and not correcting it by the correction unit can be used.

り浴槽断面積係数を設定する処理も備える。In the operation for determining the bathtub sectional area coefficient, it takes a long time to complete filling with hot water because the number of times of hot water supply is interrupted many times. Further, if the bathtub cross-sectional area coefficient varies every time the operation is performed, the water level after the completion of hot water filling also varies every time the operation is performed. Therefore, the above bathtub sectional area coefficient is determined only during the first operation after installation. In the subsequent operation, after the hot water is filled up to the water level h0, the required amount of hot water up to the set water level hS is calculated and supplied. However, if there is a failure in the first operation, it is assumed that the characteristics of the water level detection unit 2 and the flow rate of the hot water change due to aging, and the processing of setting the bathtub cross-sectional area coefficient by operating the operation unit 3 is also performed. Prepare.
