本発明は、ガス・石油等を熱源とする給湯器付自動風呂
釜の湯張り制御方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling the filling of hot water in an automatic bathtub with a water heater that uses gas, oil, or the like as a heat source.
給湯器付自動風呂釜の浴槽水位設定方法には、水位スイ
ッチ方式と水量センサ一方法とが知られている。Known methods for setting the bathtub water level for automatic bathtubs with water heaters include a water level switch method and a water flow sensor method.
前記水位スイッチ方式の長所は、浴槽中の残水量がどの
レベルであっても、湯張り量は必要水位で正しく止めら
れるが、水位スイッチユニットを浴槽の外側に器具と別
置しなければならないため、施工工事が高価で煩雑化す
るという問題点がある。The advantage of the water level switch method is that no matter what level of water remains in the bathtub, the amount of hot water can be correctly stopped at the required water level, but the water level switch unit must be placed outside the bathtub and separate from the equipment. However, there are problems in that the construction work is expensive and complicated.

めて悪いという問題がある。On the other hand, with a one-type water sensor, the installation work is simple because the water sensor can be incorporated into the fixture, but the user must check the amount of water remaining in the bathtub and correct the amount counted by the water sensor each time. For example, there is a risk that hot water may overflow from the bathtub or the water level may be lower than the required level, making it extremely inconvenient to use.

−９０６５８号参照）。In order to improve the problems of the conventional technology, the present inventors and others measured the change in water volume with respect to the water level (pressure) from the empty state of the bathtub until it reached the desired water level when installing the equipment, and collected the data. He proposed a method in which the data stored in the control device is stored in the control device, and when the appliance is operated, the data stored in the control device is used to fill hot water to the desired water level.

動停止を行なう発明が提案されている。Further, in claim 2 of the invention, when the user turns on the automatic operation switch after setting the desired boiling temperature in the controller, a certain amount of hot water is supplied into the bathtub and the pressure is increased. After removing air between the sensor and the bathtub, the water level in the bathtub is detected by the pressure sensor, and the detected value is compared with the data stored in the control device to calculate the amount of water up to the desired water level and automatically Inventions have been proposed that perform pouring and automatic shutoff.

所がある。According to the above-mentioned invention, when the amount of water remaining in the bathtub is small, the hot water is correctly filled to the desired water level regardless of the level, and a pressure sensor is installed in the device to detect the water level. The advantage is that the construction work is done using a hour wheel.

エアー抜きのための注湯が行なわれて浴槽の水位が希望
水位よりも上昇するという問題がある。However, in the above invention, in order to correctly detect the output of the pressure sensor, a certain amount of hot water must be poured during automatic operation to connect the bathtub and the appliance, and the air in the piping must be exhausted. Therefore, even if the water level in the bathtub has already reached the desired water level and you only want to raise the bathtub temperature to the set temperature, when you press the automatic operation switch, hot water is poured to remove air and the bathtub is heated. There is a problem that the water level rises higher than the desired water level.
