である。Conventional configuration and its problems Conventionally, this type of hot water mixing device has been configured as shown in FIG. That is, in FIG. 1, a valve shaft 1 is moved forward and backward by the drive of a servo motor 2. As shown in FIG. Reference numeral 3 denotes a double-sided valve on the hot water side for adjusting the amount of high-temperature hot water, and the double-sided valve 3 on the hot water side is fixed to the tip of the valve shaft 1. 4 is a single-sided valve on the water side that adjusts the amount of cold water, and a spring 5 is installed between it and the double-sided valve 3 on the hot water side.
is interposed, and is movable only in the direction of the hot water side double-sided valve 3 with respect to the valve shaft 1. Also, 6
9 is one hot water side sheet formed at the outlet of the hot water supply path 8 in the hot water side valve chamber 7, and 9 is the other hot water amount sheet formed in the hot water side valve chamber 7 opposite to the hot water side sheet 6. The side seat 9 is also arranged between the hot water side valve chamber 7 and a mixing chamber 11 to be described later. The hot water side double-sided valve 3 is installed between these two hot water side seats 6 and 9, and the hot water side double-sided valve 3 comes into contact with and separates from the two hot water side seats 6 and 9 in opposite directions as the valve shaft 1 moves back and forth. They are related and the opening degree of each can be adjusted. Reference numeral 10 denotes a water side seat formed at the outlet of the water supply channel 12 in the mixing chamber 11 which also serves as a water side valve chamber. It is designed to change and adjust its opening by releasing it. Mixed hot water, which is a mixture of hot water and water, is supplied from a mixed hot water outlet path 13, and this mixed hot water outlet path 13 is provided with a hot water temperature sensing sensor 14. 15 is a hot water supply heat source machine.

時に、給湯路８を湯側両面バルブ３が開成して行
き設定値が得られる位置まで移動する。混合湯温
が設定値よりも高い場合は、逆方向に移動する。 The operation of this conventional example is to detect the mixed hot water temperature with the hot water temperature sensor 14 and to connect the double-sided valve 3 on the hot water side with the servo motor 2 so that the hot water temperature set by a temperature setting device (not shown) can be obtained. The mixing ratio of hot water and water is changed by driving the one-sided valve 4 on the side. When the mixed hot water temperature is lower than the set value, the valve stem 1 moves to the right in the figure, and the water side single-sided valve 4 narrows down the water supply channel 12, and at the same time, the hot water side double-sided valve 3 opens the hot water supply channel 8. Move to the position where the set value can be obtained. If the mixed water temperature is higher than the set value, move in the opposite direction.

５を通る水量は規制され、設定値通りの湯温が得
られるしくみになつている。 If the hot water heat source device 15 is an instantaneous type, if a large amount of hot water is dispensed, the heating cannot keep up, and if the temperature of the hot water drops below the set value even when the water is fully closed, the valve stem will move significantly to the right. , the hot water side double-sided valve 3 approaches the hot water side seat 9. As a result, hot water heat source equipment 1
The amount of water that passes through 5 is regulated, and the system is such that the water temperature can be obtained according to the set value.
この従来の湯水混合装置は次のような問題点を
有していた。 This conventional hot water mixing device had the following problems.
(1) 給湯を行なつているか、いないかを検出する
手段がないため、給湯の停止時に混合湯取出路
１３部が自然冷却により冷えると、出湯温感知
センサ１４がこれを検出しバルブが湯の比率を
増すように移動して行くため、再給湯時に一時
的に熱い湯が出て危険であると共に、適温が得
られる位置まで移動するのに時間がかかつた。(1) Since there is no means to detect whether hot water is being supplied or not, when the mixed hot water outlet 13 cools down due to natural cooling when hot water supply is stopped, the hot water temperature sensor 14 detects this and the valve turns on the hot water. As the water temperature increases, hot water temporarily comes out when refilling, which is dangerous, and it takes time to move to a position where the appropriate temperature can be obtained.
(2) 浴槽等に湯を張る場合に所定量溜つた時点で
人間が感知できる手段がなかつた。(2) When filling a bathtub with hot water, there was no way for humans to detect when a certain amount of hot water had accumulated.
