Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a tank for a continuously controlled flush toilet that reduces the amount of water used for flushing.

BACKGROUND ART Today, seated flush toilets, so-called Western-style toilets, are used, and there are various types of flush toilets, such as deep flush type, shallow flush type, and jet flush type. Conventionally, water-saving toilets have been actively developed in order to save water even in such flush toilets. Even in such a water-saving toilet bowl, the amount of water used each time is 6 liters, compared to 9 liters of conventional deep flush toilet bowls. However, the most frequent use of the toilet bowl is to urinate. However, flushing 6 liters of water every time you urinate is too wasteful. Therefore, a two-stage structure has been proposed that reduces the amount of water used when urinating.

Problems that the invention aims to solve: However, even with a structure in which the amount of water used for washing is set in two stages, the amount of water used is limited to two values, so the minimum required amount is determined depending on the case. There was a problem that a limited amount of water could not be used, the effect was not sufficient, and it was not practical.

In view of the above points, the present invention enables stepless control of the amount of water used for flushing depending on the situation, increases the pressure of water injection into the toilet bowl, improves the flushing action, and uses it for flushing. The purpose of the present invention is to provide a new tank for a flush toilet with a simple structure and a stepless control type that is difficult to break down and can reduce the amount of water used.

Means for Solving the Problems The continuously controlled flush toilet tank of the present invention has a valve cap at the water outlet of the tank for opening and closing this outlet, and a timer connected to the valve cap by a rod. A handle is provided so that the valve cap is opened and water is poured from the tank into the toilet bowl for a time steplessly set in proportion to the rotation angle of the handle, and the inside of the tank is configured to be airtight. A ventilation hole is provided in a part of the tank, and an air valve operated by a float is installed in this ventilation hole. When the water level of the water flowing into the tank exceeds a certain value, the float rises and closes the air valve, increasing the air pressure inside the tank. The structure is such that the water pressure flowing from the water inlet matches the water pressure and the water flowing into the tank is controlled.

Function With this configuration, the amount of water injected from the tank into the toilet bowl can be adjusted steplessly, and the pre-pressure of the air in the tank increases the pressure of water injected into the toilet bowl, improving flushing performance. It is something to play.

Embodiment Hereinafter, an embodiment of the continuously controlled flush toilet tank of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a longitudinal cross-sectional view of the main parts of the continuously controlled flush toilet tank of the present invention, where 1 is the tank, 2 is the tank lid, 3 is the handle, and 4 is the valve disk.

The tank 1 also stores water, and has a water inlet 11 and a water outlet 12 at its bottom. water inlet 1
1 is much smaller than the inner diameter of the water outlet 12, the water inlet 11 is the inlet of water into the tank 1, and the water outlet 12 is a passage through which the water inside the tank 1 flows into the toilet bowl. It is. One valve cap 13 is provided at the upper end of the water outlet 12,
One end of this valve cap 13 is attached to the bottom of the tank 1 so that it can be opened and closed, and the other end is attached to a rod 34. The other end of the rod 34 is connected by fitting into a pin 33 provided on the periphery of the main shaft 32. The main shaft 32 is the tank 1
tank 1 as shown in Figure 4.
A timer 31 is attached to an external main shaft 32, and a handle 3 is provided on the outside of the timer 31.
As shown in FIG. 2, the handle 3 and the main shaft 32 have a common axis, and when the handle 3 is pushed, the main shaft 32 also rotates at the same time. The action of the timer 31 is to provide the power to slowly return the handle 3 to its original position, and its structure is similar to that of a commonly used mechanical timer.
A description of its structure will be omitted. Further, a tank lid 2 is provided above the tank 1, and a rubber gasket is attached between the tank 1 and the tank lid 2 to make it airtight, and some ventilation holes 21 are provided at appropriate places on the surface of the tank lid 2. A valve seat 5 attached to the tank lid 2 constituting an air valve is provided below the ventilation port 21. There are vent holes 51 on both sides below the valve seat 5, and a valve disk 4 is provided inside the valve seat 5. The lower end of this valve disk 4 is connected to a float 41, and the buoyancy of the float 41 is used to push the valve disk 4 upward.

Overall, the present invention uses a sealed tank 1, and between the tank lid 2 and the tank 1, an element such as a rubber gasket is used to maintain airtightness, and between the main shaft 32 and the tank 1. A seal is used to maintain airtightness. With current technology, it is not difficult to maintain the airtightness of these joints.

Next, the usage and operation of the continuously controlled flush toilet of the present invention will be explained with reference to FIGS. 1 and 3. First, to fill tank 1 with water for flushing, tank 1
When the water level rises to the point where the float 41 floats, the valve disk 4 closes the valve seat 5 (as shown in Fig. 1), the valve cap 13 covers the water outlet 12, and the water flows out. Moreover, since the valve disk 4 closes the valve seat 5, the air inside the tank 1 and the outside world are completely isolated. However, since water is still flowing in from the water inlet 11, the water level rises, and as the water level rises, the volume of air decreases and the pressure increases. The water level then rises until the value of the water gravity in the tank 1 in addition to the air pressure in the tank 1 becomes equal to the pressure at the water inlet 11, at which point the inflow of water stops. Next, when pouring water into the toilet bowl, when the handle 3 is pressed, the main shaft 32 rotates and moves the rod 34 upward, and one end of the valve cap 13 is separated from the water outlet 12 by the movement of the rod 34. (See Figure 3), the water in the tank 1 flows out from the water outlet 12 into the toilet bowl. The force of this running water is due to the pressure of the air on the water surface and the gravity of the water itself, and is much greater than the force of running water in a flush toilet due to the gravity of water alone.In other words, this example has a better flushing effect. That's what you get. Also, when the water level falls, the space inside the tank 1 becomes larger and the air pressure decreases, and the float 41 is no longer affected by the buoyant action of the water, so it descends.
Accordingly, it leaves the valve seat 5, so that outside air enters the tank 1 and replenishes the drop in internal pressure. On the other hand, the handle 3 returns to its original position due to the recovery action of the timer 31, and of course the main shaft 32 also returns to its original position, which pushes the rod 34 and causes the valve cap 13 to return to its original position. Exit 12
covered. Therefore, the amount of water flowing out in this example is from handle 3.
can be controlled by the rotation angle of the water, achieving the purpose of stepless control of water volume.

Effects of the invention According to the continuously controlled flush toilet tank of the present invention, the timer is activated in response to the amount of pushdown of the tank handle, and the amount of water flowing from the tank into the toilet bowl can be continuously controlled. Therefore, the user can adjust the amount of water flowing out to different amounts as necessary, which is extremely convenient for use, and also reduces the amount of water used for flushing.

Furthermore, the water injection force is the sum of the water's own gravity and the air pressure above the water surface in the airtight tank, so the water is ejected with much greater pressure than the water injection force of conventional flush toilets that only use the gravity of the water. Therefore, it has a good water washing effect.

In addition, since this invention uses air pressure to control the amount of water flowing in from the water inlet, there is no need to control the water inflow with rods or valves, and the structure is simple and easy to break down. This has the effect that there is nothing to do.
