Abstract

PURPOSE:To prevent the electric power from wasting by a method wherein a set temperature of water for storage hot water supply stored in a hot water storage tank with a fixed capacity is calculated from the total expected heat consumption, which is also calculated, and a heating unit is brought to a standstill, when the actually detected hot water temperature reaches said set temperature. CONSTITUTION:During operation, at a microcomputer M in an operational controlling section B, the total expected heat consumption is calculated based upon a hot water quantity (b) per person used for bathing, a hot water quantity (c) per person used for showering, a hot water quantity (d) per household used at kitchen, a hot water quantity (e) per household used at lavatory and the normal service temperature Tc, all of which are memorized in advance, and the number (n) of users, the capacity (a) of bathtub and the temperature To of feed water detected by a water temperature sensor 7, all of which are inputted separately. After that, the set temperature Tx of water for storage hot water supply, the heat quantity of the water stored in the hot water storage tank with the fixed capacity having the same temperature as which corresponds to said total expected heat consumption, is calculated. Under the conditions as mentioned above, when the actual hot water temperature Tx' detected by a hot water temperature sensor 15 reaches said set temperature Tx, the heating action of the heater 11 is stopped through a non-contact relay 17.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes low-cost electric power to supply a constant amount of hot water at a constant temperature during the night. 11ji electric power Icheon electric water heater (related to this).

! It is constructed by heating a certain amount of water for hot water supply to a certain level (generally ♂3"C) and storing it in hot water. The iML level of the water that is mixed with the water used in the fireside of the fire pit varies greatly depending on the season, and the daily usage conditions of each household (the number of people staying overnight, having guests, etc.) varies greatly depending on the season. It is i# oil that the number of friends (or whether or not to take a bath, etc.) differs from day to day, and even more so depending on the season.
-Wfd is different from the usage condition IC, which is smaller than 1. In other words, the heat stored in the 11 water vessel is constant every day, but the heat consumed -
There are many different things, and the difference between them is just 1.
Also, depending on the day, it often becomes larger. 7. The amount of heat stored in the hot water and the heat consumption. If you don't use up one cup of water that day, there will be sand and ice in the water heater. Bacteria will remain. This M!

It was made as a result of research, and its purpose was to
We provide military water heaters for military use at night that can dynamically set the amount of heat stored in accordance with the usage conditions of the military, thereby further reducing costs. There is one thing we are trying to do to make it cheaper.

Achieving the objective - Novel, this research 1C's use of Italian military power 'I Boki Rinf water vessel &; 1. , the total expected heat consumption is determined from the operating conditions and the water supply extraction temperature which are manually stored in memory in 1. At the same time, the total amount of heat corresponding to the total amount of scheduled heat 11 is stored in the fixed capacity hot water storage tank. 4) The hot water required for the hot water to be introduced was determined by the constant temperature of the water, and when the hot water was detected (immediately), the temperature was set to the n11th threshold. The heating device is characterized in that it is equipped with a control device for stopping the heating action of the heating device.

If there is ashing, the heating action starts on that Fjrt day (,j
, l, 11- are set by the power company at 10:00 or 11:00 p.m.) After iiJ, all you have to do is manually input it to the arithmetic and control unit, which is extremely easy and convenient. As soon as the water for drinking water in the hot water storage tank reaches +C, which corresponds to the amount of heat and electricity that satisfies the Ministry of Water Supply's schedule,
Since the heating action of the heating device is stopped, it is possible to use the excess treatment energy that exceeds the scheduled demand for that day's pH (<, and the residual storage at the end of the day's hot water supply).・Since the backing force can be reduced, there is almost no heat radiation loss from the conventional Yuhiki-dome storage waste and water supply, and the l-crystal LW of the hot water storage and heating water on the same day can be reduced.
Conditions i' where a, Z'j can be lowered (e.g. z0℃)
ic, t, j, and the temperature inside and outside the hot water storage tank become smaller, so based on this difference in formation, it is possible to reduce the heat radiation loss for hot water supply, and also to reduce the thermal expansion during heating. Since the heat loss caused by the discarded hot water supply river water can also be reduced, overall, compared to the conventional system, it is possible to reduce the amount of electricity used and save energy.

Hereinafter, an example of the present invention will be briefly explained based on the description of the present invention.
