とができることKなる。Figures 2 and 3 show the structure of the circulating water outlet pipe (6), which is a double pipe consisting of an inner pipe and an outer pipe, which are combined so that they can slide and rotate relative to each other. The inner tube has a plurality of elongated openings S- connected in the longitudinal direction in a straight line? The outer tube UK has a plurality of nine elongated hole-shaped openings which are spirally obliquely moved within one rotation from the upper end to the lower end. The outer and inner diameters of the inner tube υ and outer tube c12 are selected so that they are closely combined with each other, and the inner tube c11) is inserted into the outer tube as shown in Figure 3, and the two are integrated. be converted into The inner pipe c1υ has an -E lid, and a rotating shaft is provided above, and this rotating shaft passes through the upper surface of the hot water storage M11) in a transparent manner and is connected to the operating motor handle. There is also an outer/#- bottom cover 0η, and the collection row provided at the bottom is connected to the lower circulation port (3). Because of this structure, the openings s & 1 of the inner tube (button) and the openings SH of the outer tube partially overlap, and this portion becomes the circulating water outlet (71,!) opened into the hot water storage tank (11). When the inner pipe υ is rotated, the overlapping position of the openings changes, and the position of the circulating water outlet (7) can be changed in the height direction.

。In the above configuration, when the gas burner (9) is ignited and the circulation pump is operated, water in the hot water storage tank 0) is sent from the circulating water outlet (7) to the heating section (8)K via the water pipe D@. ,
The hot water is heated by a gas burner (No. 11) and passes through the hot water return pipe to the hot water storage tank (
t) K Ash, sFc hot water is stored above the hot water storage tank (1), and this stored high temperature water is constantly circulated through the hot water supply pipe and the water heater (IF4, return pipe), and the pulp is opened with the hot water supply tip shaft. The high-temperature water can be used immediately.The temperature of the high-temperature water to be supplied is detected by a temperature sensor@, and the gas valve is controlled by the controller 121K to maintain the set temperature.

The set water temperature of the tap water outlet (1i), which is set by
When starting boiling from raw water, the VC controller drives the operating motor 4, and the first point of the trowel is the circulating water outlet (7).

。From this K, there is a low-temperature main body where hot water is taken out from the circulating water outlet (7), a hot water storage tank (close to the Takajimoto layer where hot water is being stored in the upper part of 11, this 1ii6i! Heat transfer calyx from water, etc.) Since the water is taken out from the humidified portion where the temperature is considerably high, only a small amount of thermal energy is required to heat it to a predetermined temperature, and a quick start-up is realized. As the amount of stored hot water increases, the circulating water outlet (1) gradually decreases, and when the water storage lid decreases due to water reduction, the circulating water outlet (1) increases accordingly, always keeping the set water temperature. Heating can be efficiently performed while taking out low-temperature water that is several degrees lower. In this way, at the time of death when the whole boils, the circulating water outlet (7) has fallen to the lowest level 4i1, and the gas valve is controlled to maintain the set temperature.

を沸かすような無駄が防止される。In the above example, the position of the circulating water outlet (7) is controlled by the difference in water temperature between the lower circulation port (3) and the hot water outlet (ml), and the capacity of the heating section (8) controls the amount of hot water supplied. When the amount of hot water is exceeded, the amount of stored hot water gradually increases, and when the maximum IC is used, the entire body boils, and when the planned amount of hot water used is small, there is waste. In this case, for example, the actual capacity of the hot water storage tank (1) is set small by setting the circulating water outlet (7) so that it does not fall below a certain height. In addition, if the amount of stored hot water decreases due to hot water supply after 90 minutes of boiling, the amount of water supplied corresponding to the decrease is detected by measuring the amount of water supplied, and the position of the circulating water outlet (1) is adjusted to It can also be used to increase the INK and compensate for the drop in humidity of high-humidity water using the heating section (hat), while using up all nine boiling water. Therefore, in this case, wasteful use of KFi, such as newly heating low-temperature water and boiling more water than planned for use, is prevented.

水量を制限するように#l成してもよい。In addition, when hot water is supplied beyond the capacity of the heating section (3),
Since it is conceivable that the hot water storage temperature will gradually decrease and eventually the hot water supply temperature will decrease, the following control is performed to prevent this. That is, when the circulating water outlet (7) rises to the top and the temperature of the tap water outlet (11) becomes lower than the set value, the pulp ratio η is controlled by the operation morph @, and the water supply port ( 2) The amount of hot water supplied is suppressed by limiting the amount of water supplied. From this k, hot water is supplied at a predetermined temperature with the minimum amount of hot water, and 4
! It can be used in any capacity. In addition, Jin's pulp @IJF1 is installed separately from the circulating water outlet pipe (6) in the figure, but this pulp gate is installed, for example, in the lower part of the circulating water outlet pipe (6) to prevent the inner pipe υ. #l may be configured so that the circulating water outlet (1) moves to the top in conjunction with the rotation and automatically limits the amount of water supplied at the time of death.

温度を自由に加減することができる。Also, depending on the purpose of the hot water, hot water at a lower temperature than the stored high-temperature water may be required, so in this case, lower the circulating water outlet () to a lower position and (3) The water temperature is kept low, and the ashes are mixed with the slightly lowered high-temperature water coming from the return pipe n and taken out from the branch pipe. You can freely adjust the temperature.

配列定することが必要である。In the above-mentioned embodiment, the heating part (8) is installed separately from the hot water tank 1g1tf (!), but it is also possible to incorporate the heating part (8) into the hot water tank 111 and integrate it. The circulation between the water storage tank (8) and the hot water tank (11) can be done by natural circulation.Also, the opening s of the circulating water outlet pipe (6)
-@4 may have nine vertically continuous slits, or may have continuous circular holes. In this case, the inner tube -
Even if the angle of the combination of No and outer tube changes, the opening 5as
It is necessary to arrange the shape and shape of the openings HNO so that the effective area of the circulating water outlet (1) formed by overlapping HNOs is constant.

い。In addition, in the above embodiment, the heating section (1) is controlled by controlling the gas valve.
Although the water temperature at the outlet is controlled by adjusting the amount of input to the outlet, the gas valve (c) is assumed to have only the ability to open and close, and the amount of input is kept constant. A flow rate adjustment valve is installed in a part of the circulating water path such as water pipe A and return pipe #4, and the flow rate of the circulating water is adjusted to control the water temperature at the outlet (I). Good too.

を得ることができる利点がある。As mentioned above, one aspect of the present invention is that the position of the circulating water outlet from the hot water storage tank to the heating section can be changed continuously in the height direction of the hot water storage tank. It is easy to obtain hot water, and the amount of hot water stored can be adjusted arbitrarily according to the load, thereby preventing wasted thermal energy due to boiling more than necessary, and wasteful increase in heat dissipation due to an increase in the number of hot water storage lids. This makes it easy to perform various controls depending on the purpose by using it in combination with various types of senna.
This has the advantage of providing a hot water storage type water heater that is easy to use and energy efficient.
