Description

  The present invention can regenerate industrial elements such as a thread-wound filter that can separate trash etc. and the filter itself from the time when bathing in hot water in a relatively low temperature and slightly high temperature bath is completed. It is possible to regenerate and filter the hot water after filtration to the extent required by the Waterworks Law, and to prevent the heat of the filtered hot water from being released into the atmosphere via a super-fine filtration device using a removable ceramic membrane filter. By eliminating wasted energy, we intend to provide equipment that reduces costs and counters CO2.

  Conventionally, the last person who took a bath in a bathtub often leaves hot water as it is, but the upper part of the bathtub is an open type, and the outer periphery of a traditional wooden, plastic, stainless steel bath is covered with a heat insulating material, Countermeasure goods such as floating on the market are commercially available, but the fact is that the thermal insulation effect is small.

  Therefore, although housewives are aware even in ordinary households, in summer and winter, especially when the bath is boiled every day, in summer there are many cases where the gas cost is about half that of winter, and late-night power Most of the hot water used after bathing in hot water heaters and natural refrigerant heat pump water heaters (trade names: Eco Cute, Eco Jaws, etc.) is discarded.

  Of course, there are differences in the energy of boiling in summer and winter, but in the situation where there are few `` bathrooms '' in the neighborhood like in the past and indoor baths are common, the loss of energy is large because it is everyday. As in the present invention, the hot water in the bathtub can only be used as washing water as the remaining hot water, but in reality, the "water" used for the bath is nearly 200 liters a day, so in 30 days As much as 6 tons of water per month is discarded without being regenerated.

  In the present invention, as a countermeasure against this, a regenerative ceramic membrane filter capable of separating dust and debris by ultra-precise filtration of hot water can be obtained according to “Caspack Filter Housing Device” Patent 2002-244346, Utility Model No. 312456, Utility Model No. 312473. Water can be purified by reducing the number of filters used and reducing the accuracy to the level specified in the Water Supply Law each time. If necessary, the filter can be separated and removed as dust, debris, and bacteria using a backwashing system using air. And played.

  However, in the filtration with a general industrial element, the filter has no choice but to dispose of waste and waste. In this case, the filter is incinerated as burnable waste from the home, which may cause CO2 generation by incineration. The cost and replacement of the filter element are also great.

  The problem to be solved is that if the hot water to be poured into the hot water tank is dirty, the inside of the hot water tank will be dirty, and the heat retention of the hot water tank, convenience at the time of loading, and convenience at the time of taking out will be poor. The efficiency of heating water is poor at about 40 ° C.

  When you return hot water from the hot water tank to the bathtub, you will bathe from now on, so you need to return it quickly and adjust the amount of hot water, and you want to return to the hot water quickly. It is thought that it does not have to be so fast, and it is indispensable to suppress the growth of Escherichia coli and other bacteria so that the hot water after filtration satisfies the water quality standard of the water supply law (30 pieces / milliliter or less).

In the present invention, when hot water is pumped from a bathtub to a hot water tank, as a means of fine filtration, a ceramic membrane filter is used to reverse separation of dust, debris, bacteria, and virus by air with a ceramic membrane on the surface of the filter. The filter can be regenerated by storing it in a non-woven cloth bag provided below by washing, but a general industrial filter element costs about 700 yen per piece, so it is several to tens of times depending on how dirty the bathtub is However, there is a problem that the discarded items are only incinerated and much time is required for replacement.
In general, the hot water in the bathtub is considered to be considerably dirty from the water quality standard depending on the number of people taking the bath and the degree of dirt of the person. For this reason, in an ordinary industrial filter element, discarding one to two a month Therefore, the generation of CO2 due to this incineration cannot be made foolish.

  As an effect of the present invention, in the filtration method using a ceramic membrane filter, hot water can be regenerated from high temperature to low temperature, and it can be separated into dust, waste and bacteria, and separated into a non-woven fabric in a pack form. Each time the hot water is stored from the bathtub to the filtered hot water storage tank, only the hot water from which dust, debris, bacteria and viruses have been removed is stored. It has the characteristics to be.

  The hot water stored in the hot water storage tank is cleaned and the temperature of the hot water is maintained, so that the energy usually radiated into the air is minimized, so that the reheating energy can be reduced.

  A hot water tank is a device that stores hot water that has been cleaned from a bathtub with a ceramic membrane filter, but it can also be returned to the bathtub as it is, and the hot water stored in the hot water tank can be used for electricity, gas, etc. Naturally, it can be reheated in the case of gas. In the case of gas, after returning hot water to the bathtub, additional water is added according to the amount of hot water, and additional cooking is done to eliminate waste of energy, reducing CO2 emissions and using water This is a low-cost domestic filtered hot water storage tank device that contributes to reducing household household expenses by eliminating waste.
