Abstract

<P>PROBLEM TO BE SOLVED: To stably use rainwater by using remaining water in a bathtub, because unfortunately it has not rained at all since immediately after the construction of the rainwater utilizing tank, though the rainwater utilizing tank is constructed by taking advantage of a subsidy equivalent to about half the construction cost of the rainwater utilizing tank, on the grounds that the remaining water in the bathtub has been discharged into sewage except that about half the quantity of the remaining water has been used for the cleaning of a bath, washing, the cleaning of a toilet, floor wiping, etc. over a long period of time. <P>SOLUTION: In this system, the utilization of the remaining water in the bathtub is focused on. Water from public water supplies is hardly used though the remaining water after the completion of washing is pumped up by a submergible motor pump every day. The remaining water has only to be pumped up about every two days in the case of a household in which the remaining water is not used for the washing. The water is periodically sterilized because the water in the bathtub is to be used. Furthermore, when one or two tanks are added, the rainwater can be more stably utilized by temporarily storing the rain. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  In the present invention, bath water after taking a bath is put in a tank and the water is used as toilet water, so-called middle water. Hot water is used. Toilet water is about 100 liters on average for a family of four, and around 150 liters on Saturdays and Sundays, so we want to keep the remaining hot water from the bath with a submersible motor from the bathtub to about 200 liters. The 200 liter tanks are rugged, so they are expensive and very heavy, so 100 liter tanks are arranged in a rack, and there is a hole through which the hose passes. By adding water from one side to the other, it becomes siphoned and 200 liters of water can be injected at a low cost.

Conventionally, rainwater use devices have collected rainwater from the roof surface and used it for toilet wash water. However, if the water quality is not good, or if it rains, it overflows. The ones that use bath water that must be used are expensive, and these also overflow if the pump is not switched off.

  It is extremely uneconomical that washing water in conventional flush toilets is solely dependent on water supply, and even though it is part of the remaining hot water in the bath, the excess after use as washing water is discarded as waste water Is also very uneconomical and problematic from the perspective of effective use of precious water resources.

  The present invention has been devised in view of the problem of lyricism, and has been devised so that the remaining hot water of a bath can be used as washing water for washing away the feces and urine of a flush toilet. It aims to provide a very economical flush toilet.

  Also, to prevent rainwater from overflowing, let the ball enter the rainwater inlet to prevent overflow. In addition, if the remaining hot water of the bath is poured from the rainwater inlet, it will not overflow with the ball and will flow from the other bowl.

  In the case of a detached house, as an improvement measure, if it is a family of four who manually set the underwater motor after taking a bath, it can be adequately covered by putting it in a tank. However, since it is useless to use rainwater, the bath water is used as laundry in the morning, and the remaining hot water after that is put into the toilet tank.

  In order to solve the above problems, in the present invention, initial rainwater is first stored in the upper tank, and if it does not rain using a switching valve, the remaining hot water in the bath is used, but if water still remains. A switching valve that flows into the sewage is attached for effective use of water.

  When a large amount of rainwater is used, dust is contained, pH adjustment, sterilization, etc. are troublesome, but such trouble is not caused by preferential use of bath water.

  Take a transparent tube from the bottom of the tank and bring it to the top so that you can see how much water will occasionally get in, and put a colored float in it so that you can see how far the water is in from a distance become.

  When the water in the tank runs out, the three-way valve switches to the water supply and the toilet can be used as it is.

  Since the amount of bath water used is generally determined by the household, determine the amount of rainwater inflow and determine the amount of rainwater. Determine where to stop the rainwater of the ball, and if it is full, let it escape to other kites. .

  Since the present invention can use both the remaining hot water and rainwater in the bath, even if the flush toilet is used excessively, the remaining hot water and rainwater in the bath can be used as washing water for washing away urine, which is extremely economically advantageous. In addition, there is an excellent effect that the remaining hot water and rainwater in the bath can be effectively used as valuable water resources.

  In order to make the content of the present invention easier to understand, a detailed description will be given below with reference to examples.

  The present invention gives priority to the remaining hot water of the bath of the bathtub 11, and in most households, the water of the toilet 12 can be supplied with only the remaining hot water, and even in the home where the remaining hot water of the bath is used as washing water, If it rains even once, it is not necessary to use the water supply 15 even in the home of four people.

  Although the present invention has priority over the remaining hot water of the bath of the bathtub 11, it is partially used as washing water, and if it does not rain, naturally there will be insufficient water and no water will be discharged from the water pipe 17, only at that time the three-way valve 1 uses the water supply 15.

  In the present invention, the remaining hot water of the bath of the bathtub 11 is put in the water pipe 13 every day using the submerged motor 16, and if the remaining hot water of the bath is put in every day, too much naturally occurs and overflows. Avoid overflowing with a ball that stops when the rainwater or remaining bath water is full.

  In the present invention, a 200-liter tank is sufficient even for a family of four, but a 200-liter tank is large, heavy, and expensive, so purchase 100-liter tanks 7 and 8 and install a hose on the top. Make a hole to pass through, and put the hose on both bottoms to make the water siphon 3 state.

  The present invention is deeply related to the weather, and even if it rains too much, the tank overflows. Therefore, if the ball 4 is threaded 5 and there is a lot of water, this ball will hold the pipe 9 and more water will enter. Do not.

  In the present invention, when there is a ball when it rains too much, if you are worried or how long you are using it a day, you made a hole in the bottom of the tank and put a transparent tube so that you can see the water level 6 .

  The present invention is economically advantageous because there are places where subsidies are issued depending on the local government by using rainwater.

  According to the present invention, some households have excess water. Therefore, water can be sprayed from this tank to plants such as flower beds and lawns.

  In order to use rainwater, nets (stockings) are used because small leaves etc. are inevitably contained, and hair is used to use remaining hot water in the bath.

  Since bacteria such as occurs in just the water for using remaining water bath, bear in mind as disinfection to.

  Since the use of water can be saved, it becomes resource saving and energy saving. Therefore, if this can be spread, water of about 20% to 30% can be saved.

Arrangement example in case of detached house When the water level is low for the parallel tanks in the enlarged views of Figs. When the water level is high in the case of the parallel tank in the enlarged views of FIGS.
