Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet capable of changing the amount of flush water (total amount of flush water) and / or the flow rate (flow rate) of flush water for flushing waste after use.

[0002]

2. Description of the Related Art Originally, the amount of water used to drain waste such as stool is determined by each local government.
In Japan, facilities such as toilet bowls and tanks are designed so as to mainly use 6 to 8 L of water. However, during droughts, it is common to hear that the amount of waste water is wasted.

[0003] Conventional water-saving toilets capable of adjusting the amount of water for flushing wastes include, for example, JP-A-8-113969 and JP-A-9-41460. That is, JP-A-8-113969 and JP-A-9-4
1460, all attempts to conserve water by controlling the flow rate of wastewater by adjusting the water level when the water in the water storage tank attached to the flush toilet is full. This is a solution for the user to put a plastic bottle filled with water in the water storage tank, adjust the water level, and control the amount of water flowing the waste as a water saving method for draining waste. Although good, there is also a situation in which a foreign matter such as a PET bottle enters the tank and destroys parts inside the water storage tank.

[0004]

However, the conventional apparatus has the following problems. That is, in each of the above patents, the amount of water stored in the tank is changed by changing the position of the float (floating bag) that determines the water level when the water storage tank is full, and as a result, the water flow is controlled to save water. Since the water is present in the tank, the user must adjust the float by changing the position of the heavy water tank by opening the lid of the heavy water tank, placing the hand in the water tank, and then again. I had to go through the procedure of closing the lid, and it was troublesome.
In other words, the user can determine the amount of waste discharged at that time, its viscosity,
Or, even in the event of water shortage, it is difficult for the user to adjust and control the amount of washing water to be flown by himself, which has been extremely inconvenient.

The present invention solves the above-mentioned problems of the conventional technology. That is, the user himself / herself determines in advance the flow rate and / or flow rate of the wash water for flushing waste such as urine.
An object of the present invention is to provide a flush water variable toilet having a function that can be easily adjusted and controlled from the outside of a water storage tank.
