のがあった（例えば実開昭５５−５９２２３号公報）。2. Description of the Related Art Conventionally, there has been an automatic water heater of this type as shown in FIG. 7 (for example, Japanese Utility Model Application No. 55-59223).

比率が変えられる。In FIG. 7, a hot water side valve body 5 and a water side valve body 6 are attached to a shaft 7 in a valve frame body 4 having an inlet 1 for hot water, an inlet 2 for water, and an outlet 3 for mixed hot water. It is fixedly installed. The shaft 7 is driven by a motor 1O via a screw mechanism 8 and an external reduction gear 9, and the hot water side valve body 5 and the water side valve body 6 change the mixing ratio of hot water and water.

蛇口１４から給湯箇所に給湯される。The mixed water temperature is detected by a thermistor 11, and this detection signal is compared with a set value of a setter 12 by a controller 13, and the motor 10 is adjusted. The mixed hot water is then supplied to a hot water supply point from a faucet 14 provided at the terminal.
発明が解決しようとする課題
しかしながら上記構成の自動給湯装置は、次のような課
題を有していた。Problems to be Solved by the Invention However, the automatic water heater having the above configuration had the following problems.
（１）各給湯箇所への流量の制御を、手動で蛇口１４に
て行わなければならないため、給湯箇所で必要とする流
量を即座に得ることができなかった。(1) Since the flow rate to each hot water supply point had to be controlled manually using the faucet 14, it was not possible to immediately obtain the required flow rate at the hot water supply point.

弁体５で湯側を全開とし水側弁体６で水側を全閉として
も、所望の温度が得られないことがあった。(2) When an instantaneous water heater or a boiler with a small amount of canned water is used as a water heater, the heating capacity is limited, so if the flow rate is too high at the faucet 14, the temperature will drop below the temperature set on the setting device 12. The temperature of the hot water entering from the inlet l has dropped, and even if the hot water side is fully opened with the hot water side valve body 5 and the water side is fully closed with the water side valve body 6, the desired temperature may not be obtained.
本発明は上記課題を解決し、各給湯箇所の使用量に対し
適正で、給湯機の能力不足の影響を受けにくい流量で給
湯が行われる、自動給湯装置を提供する。The present invention solves the above-mentioned problems and provides an automatic hot water supply device that supplies hot water at a flow rate that is appropriate for the amount used at each hot water supply location and is less susceptible to the effects of insufficient capacity of the water heater.

頻繁な発停を防止する。Operation With the above configuration, the automatic water heater of the present invention controls the flow rate according to the setting of the seasonal setting device, thereby suppressing the flow rate when the hot water supply function is insufficient in winter, and increasing the flow rate when the hot water supply function is surplus in the summer. This prevents the issue of not being able to reach the desired hot water temperature by flowing a large amount of water, and the frequent starting and stopping of the water heater due to restricting the flow rate too much in the summer.

It is determined based on the graph shown in FIG.

This figure shows the relationship between the temperature of water entering the water heater and the flow rate based on an instantaneous water heater (1/H). It can be seen that when the water temperature is low, it is difficult to obtain high temperatures unless the flow rate is reduced. For example, if you want to obtain a mixed water temperature of 50°C or higher in the mixing valve 26, when the water temperature is low in winter, it is 8.81! ,/llll1n
You can see that you can do the following. Further, in the middle season, the flow rate may be set to 11.41 /min or less, and in the summer season, the flow rate may be set to about 161 /min. In the above example, the temperature in winter is 817m1n, taking into consideration piping heat radiation loss, etc.

shall be defined as in. However, when supplying hot water to bathtubs that require high temperatures, the above value will be increased by 11/lll1n for hand showers 29, fixed showers 30, and washing area washrooms 31, which only supply hot water below 45°C. Another idea is to supply hot water at the same value.

給湯を止める。If you want to increase the flow rate even if the instantaneous hot water heater 15 has insufficient capacity, or if you want to further reduce the flow rate,
The change can be made manually by pressing the high switch 68 and the low switch 69. In addition, in consideration of cases where the actual water temperature is lower than the water temperature set by the seasonal switch 76 or the flow rate is too high due to variations between products, the deviation determination section 78 compares the set water temperature with the actual water temperature detected by the thermistor 51. If the deviation in water temperature is not resolved even after a predetermined period of time, increase the flow rate by 1! /min aperture, and if the deviation is not resolved even after checking the predetermined time deviation, increase the aperture by 1 j2/min.
Continue squeezing. If the deviation is not resolved even after reaching the minimum flow rate of 6 ffi/min, it is determined that the hot water has run out and the hot water supply is stopped.

くスイッチ６５、ぬるくスイッチ６６で変更ができる。The mixed water temperature is adjusted according to the settings of the bathtub water temperature volume 74 or the shower water temperature volume 75, and can be changed using the hot switch 65 and lukewarm switch 66.
更に、季節スイッチ７６の設定により、例えば冬期は熱
目に設定温度に自動的にｌ″Ｃを加算し、夏期はぬる目
に設定温度から１°Ｃを減算して自動設定されている。Further, depending on the setting of the seasonal switch 76, for example, in winter, 1"C is automatically added to the set temperature for hot weather, and in summer, 1°C is automatically subtracted from the set temperature for warm weather.
特に冬期にさめやすい浴槽の湯張り温度は、特別に＋３
°Ｃとするようなことも可能である。The temperature of the hot water in the bathtub, which is easy to cool down especially in winter, is specially increased by +3
It is also possible to set the temperature to °C.
基本的に、給湯機の能力と水温と出湯温度を流量の関係
は、次式で表される。Basically, the relationship between water heater capacity, water temperature, hot water temperature, and flow rate is expressed by the following equation.
給湯機能力＝比例定数×流量×（出湯温度−水温）
従って、一番正確に適正な流量値を得るには他の３つの
条件が分からないと計算ができないが、本発明は一つの
条件でしかも使用者が一番分り易い季節をもって、流量
値を全（情報がない状態よりも、より正確に定められる
という所に特長がある。Hot water supply function = proportionality constant x flow rate x (output hot water temperature - water temperature) Therefore, in order to obtain the most accurate and appropriate flow rate value, calculations cannot be made unless the other three conditions are known, but the present invention can be calculated using only one condition. Moreover, the feature is that the user can determine the flow rate value more accurately based on the season that is easiest for the user to understand than when there is no information.

ある。In addition to this method, - conditions can be set based on the hot water supply function or hot water outlet temperature (equal to the mixing valve outlet temperature when the hot water side is fully open), or two of the three conditions: hot water supply function, hot water outlet temperature, and water temperature. There are ways to combine them, and ways to use all three conditions. Furthermore, there are two methods for determining these conditions: a method in which these conditions are determined and set by a person, and a method in which they are actually measured using a sensor.

使うことは、構成の簡略化の上でも意義がある。In particular, determining the flow rate using a seasonal switch that represents water temperature and a signal from a hot water temperature setting device that sets the temperature of the hot water mixing valve is a practical method that allows the flow rate value of the above embodiment to be determined even more accurately. be. In particular, compared to a hot water supply function switch that is provided only to set the flow rate, using the signal from the hot water temperature setting device is significant in terms of simplifying the configuration.
