Abstract

PURPOSE:To reduce the heat loss of heated water located at an upper portion of a bathtub, by increasing the rate of the quantity of heated water located above the outlet of heated water to the quantity of water located under the outlet of heated water by lowering the positions of a water suction port and the heated-water outlet port. CONSTITUTION:An upper attachment 4 and a lower attachment 5 are attached respectively to an upper port 3 and a lower port 1 of a water circulating passage through which water is circulated from the lower port 1 of a bathtub to the upper port 3 via a heat exchanging section 2 of a bath boiler, so that a water circuit 12-1-2-3-(9,8) is constituted between a water inlet port 12 of the lower attachment 5 and a heated-water outlet port 9 and a deaerating port 8 of the upper attachment 4. With such an arrangement, reverse convection of water after stopping of heating is prevented by a check valve 11, so that the bath boiler is prevented from functioning as a cooler.

Description

DETAILED DESCRIPTION OF THE INVENTION The connection of the bathtub connected to the cooking stove, which is currently popular, is based on the following 171
Because of this, when boiling water, if you raise the water 10 cm above the top and stir it once to reach the appropriate temperature for bathing, the temperature of the water must be close to one boiling point. The amount of water emitted from the surface of the tube is not too high, and the rise in water temperature after passing through the needle once is usually 40 to 50 C in a steady state. If the humidity rises further than that, the efficiency will be very poor, so it is better to boil the water up to 220cm than in [2] because the temperature of the whirlpool stays below 70°C, which results in better thermal efficiency and lower fuel costs. Things are going to get cheaper.

In addition, the higher the heating efficiency, the better the performance as a heat exchanger, and therefore, after the addition of J and stop F, the hot water in the moat is cooled as a cooler, so the temperature decreases and the specific gravity becomes heavier. The water that has been drained falls along the slope inside the tub and causes convection that is opposite to that during heating, which lowers the water temperature in the bathing tub.
The current situation is that fuel costs are increasing for one cooking. The actual Jη1 was developed to improve these drawbacks (an example will be described below).

To explain the diagram, the water coming out from the bottom day 1 of the bathing side through part 2 of the flea heat exchanger and from the top day 3 separately to the upper and lower mouths of VIF'J times ■-δ, respectively, 8''. Attach the partial connection port 4 and the bottom connection port 5, and connect the bottom 8] By forming the water circuit 9, 8), even if water is sucked in from the bottom of the bathtub and hot water is discharged from the opening 9, which is lower than the conventional outlet 3, both the inlet and outlet can be lowered. Since there is no change in the water head difference, no abnormal pressure rise occurs, and 12
→ Since the deaeration hole 8 is provided at the top of the zaiphone created by the circuit 2-3-9, there will be no air pockets near 3 when supplying water to the bathtub, which occurs when boiling water. R1 for dissolved air! Air and water? Since the gas also escapes through the deaeration hole, there will be no distortion or damage to the pipes caused by an abnormal pressure rise.Also, although some of the lagoon will escape from the deaeration hole, it will be much smaller than the outlet in point 9. Since the area is small, the large part] will come out downward, so the opening of 3 and the opening of 9
Since the thirst part increases by the difference between the mouth and the mouth, the ratio of the hot water part to the water part does not have a double effect because the water decreases by the amount of hot water that increases. + of hot water
m 11. (By keeping it at 50-60C and stirring it once, you can make it to 43C, the appropriate humidity for bathing, so less heat is lost to the latent heat of vaporization from the surface of the lagoon, so the fuel for heating is reduced.) It is possible to save more than 10%.Also, the temperature rise due to passing through the 1-2-3 circuit once is generally in the range of 40 to 50C, and efficiency is also good, but the ratio of water to lagoon is large. If the temperature of the water supply is below IOC, it is necessary to stir the water to 1 F during heating.
Furthermore, if we take into account that heating is performed within the inefficient range of γ and +4 degrees difference, and that the heat carried away by the water is also large due to the high temperature of the lagoon, this results in a large savings.

In addition, the lower connection [5] should have rubber folds 10, etc. on the upper part of the lower part I (= 1 digit ♂) and 5 ah on the check valve, and the check valve should have a mounting hole. Mouth! , with the structure that opens and closes the AV radiation from the center of the [ It can be fixed in a removable manner.During heating, the water that enters from the opening of 12 flows through the reverse well valve 11.
It is heated in the order of 2-3-9 and comes out from below from the conventional opening 3 as a lagoon, but the reverse convection after the heating is stopped is blocked by the valve 11 in the reverse 1, so the pot acts as a cooler. It can prevent heat loss due to working, and combined with the effect of lowering the discharge port of the lagoon mentioned above, it produces a great old energy effect.

Also, unlike conventional methods, special construction is difficult.
・? It has many features, such as being simple, safe, easy to remove, easy to clean, and can be kept clean at all times.
