JPS60235949A - Performance improving device of circulating type water heater - Google Patents

Abstract

PURPOSE:To heighten the efficiency of a heater and to heat water quickly and to remove the danger of scald by a method wherein water in a water tank is supplied to the heater mechanically from one of passages of the circulation type water heater, and is made to circulate compulsively. CONSTITUTION:The water in a water tank 1 is supplied into a heater 2 mechanically, for instance using a submerged pump 4 etc. from one of the water passages of the circulating type water heater 2, and is made to circulate compulsively. Hereby, the efficiency of the heater 2 is heightened and water is heated quickly and the danger of scald is removed as well as the residence of scales, impurities etc. can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to energy saving, safety, and hygiene. Circulating water heaters for baths, etc., which are currently in widespread use, have the drawback of secondary boiling.

(There is a waste in absorbing 11 firepower.

12) Because the water is hot, there is a risk of burns.

(3) Dirt and dirt tend to accumulate inside the pot, making it unclean.

This is the main thing.

The present invention solves these problems all at once by forcibly circulating the water in the pot when used in an underwater phonf, etc.

First, I will talk about energy savings and safety. 9 The principle of this kettle is that as the hot water, which is heated and has a lighter specific gravity, rises in the kettle, cold water is sucked in from the lower water outlet and circulated naturally. .

In this case, when the heat is on track, you can hear the sound of boiling inside the pot.

This may seem like it is boiling nicely, but in reality, the water in the pot has reached its boiling point and cannot accept any more heat from the outside. There is one cost of energy here.

Heat, like electricity, water, and air, has the property of moving from a higher temperature to a lower temperature, and the greater the temperature difference, the greater the amount of heat transferred.

Therefore, it is important to keep the water temperature in the pot as low as possible.

In the present invention, by mechanically applying pressure and forcing 9 circulation, the inside of the pot is always kept at a low temperature, improving the heat absorption rate, boiling water quickly, and saving energy. You can save time. The experiment was conducted in my own bath (firewood, tile), and I tried to keep the heat as constant as possible.

Water was supplied from outside the tank using an electric pump (water discharge rate: approximately 50 liters per minute).

Since the bathtub is cold, in order to make one condition the same, first,
After heating the bathtub to around 50 degrees Celsius, I threw out the water and compared the conventional method and using a pump.

How long did it take to warm the fish to 45℃?

Traditional method: 45 minutes, Pump use: 34 minutes.

It was confirmed that the difference was 11 minutes, or about 24 inches, and that time could be saved.

Maruko, the temperature of the water coming out of the pot is when the water temperature in the bathtub is 40 degrees Celsius.

When using the conventional method, the temperature was 72°C.

When using a pump, the water does not come out at temperatures above 43°C, so it is safe to reheat the water while taking a bath.

Next, let's talk about hygiene.

This kettle has a complex structure with a double point placed on it, so it is easy for dirt and grime to accumulate inside due to natural circulation, and it is extremely filthy or structurally There is no way to clean it from the outside.

For this reason, special detergents and equipment have been devised, and specialized companies have also appeared, and when you ask them to do it.

The current situation is that it costs 32,500 yen every six months.

In the present invention, the interior of the pot is constantly flushed by forced circulation, so there is no room for dirt to accumulate, making it sanitary and freeing you from troublesome cleaning.

Incidentally, this kettle also has the disadvantage that when the fire is turned off, it acts as a cooler, so it gets cold easily.1 In the present invention, the backflow prevention device of the pump prevents the inflow of cold water from the kettle. It also has the effect of keeping you warm.

In addition, it is desirable that the sui-sochi of the water supply motor be linked with the combustion gas switch.

Claims (1)

[Claims] By mechanically (for example, using a submersible hop, etc.) water from an aquarium is fed into the pot from one water outlet of a circulating water boiler (bath, pool, etc.) and forced to circulate.
A performance improvement device for a circulation type water boiler that increases the efficiency of the water boiler, boils water quickly, eliminates dangers caused by boiling water, and prevents dirt and grime from accumulating in the pot.
