Description

[Detailed description of the invention] Industrial applications The present invention relates to a flushing device for a flush toilet.

Configuration of conventional examples and their problems The most common conventional toilet flushing device includes a valve opening means for opening and driving a valve located in a cistern to release water stored in the cistern, and a valve opening means that penetrates the wall of the cistern to release water stored in the cistern. The shaft is provided with a penetrating shaft, one end of which is connected to the valve opening means, and the other end outside the cistern connected to a manual drive means such as a manual lever, and when washing with water, the manual drive means is connected toward the cistern side. In most cases, the pressure was applied manually. However, since the flushing operation must be performed after getting up from the toilet seat after using the toilet, it is important to realize a clean and convenient configuration that automatically flushes the toilet when you get up from the toilet seat. There is a high demand, and in actual use, it is often necessary to flush even when sitting on the toilet seat with your back to the cistern, and this is especially noticeable for women. It is necessary to twist the body in this state, and there was a high demand for a configuration that would eliminate this difficulty of use.

As a solution to the above drawbacks, within Cistern,
It has also been considered to provide an electromagnetic drive means, such as a large solenoid, for driving the valve open, and to flush the toilet by electrically energizing it with a rise signal from the toilet seat or a flush switch signal. However, when I actually operated it, I found that most of the inside of the cistern was
Due to the high humidity of nearly 100%, corrosion of the electromagnetic drive means progressed rapidly, leading to accidents such as coil breakage and electrical leakage.

Furthermore, as a solution to the above-mentioned drawbacks, a structure was devised in which an electromagnetic driving means that is sensitive to humidity is installed outside the cistern, as shown in FIG. In Figure 1, 1 is a toilet bowl, 2 is a cistern that stores water for flushing the inside of the toilet bowl 1, 3 is a toilet seat, 4 is a lid, and 5 is at the rear of the toilet seat 3, so that the toilet seat 3 and lid 4 can be rotated freely. A case for supporting and housing the control device 6; 7, a toilet flushing device mainly consisting of electromagnetic driving means; 8, electric wires connecting the control device 6 and the toilet flushing device 7; 9;
is installed in a through hole provided in the wall of the cistern 2 and is rotated by the toilet flushing device 7. A through shaft 10 is a lever that rotates together with the through shaft 9, 11 is a chain, and 12 is rotated by the rotation of the lever 10. This valve opens when the chain 11 is pulled up and releases the water stored in the cistern 2 into the toilet bowl 1.

In the above configuration, although not particularly shown in the drawings, the toilet installed in the cistern 2 is connected via the control device 6 to a means for detecting that someone has stood up from the toilet seat 3 or a signal from a flush switch provided on the case 5 side. Since the flushing device 7 can be energized and flushed, both convenience and cleanliness are satisfied, and since the electromagnetic driving means is housed in the toilet flushing device 7 installed outside the cistern 2, the electromagnetic This eliminates the need for the drive means to be constantly exposed to the high humidity atmosphere within the cistern 2, and eliminates accidents such as coil breakage and electrical leakage.

However, since it is necessary to flush by overcoming the water pressure applied to the valve 12, the torque required for the electromagnetic drive means is as large as 10 kg-cm, and a toilet that accommodates a large electromagnetic drive means that satisfies this requirement is required. The water washing device 7 also has to be large. As a result, when the toilet seat 3 or lid 4 is opened, it hits the toilet flushing device 7, which prevents the toilet seat 3 or lid 4 from standing up, and the toilet flushing device 7 is larger than the cistern 2, resulting in an extremely poor appearance. Problem has occurred.

Purpose of the invention The present invention solves such conventional problems,
The purpose is to provide a toilet flushing device that is excellent in terms of convenience, cleanliness, safety, durability, and appearance.

Structure of the Invention In order to achieve this object, the present invention provides a valve opening means for opening and driving a valve in a cistern for releasing water stored in the cistern, an electromagnetic driving means for driving the valve opening means, and an electromagnetic driving means for driving the valve opening means. The electromagnetic driving means is hermetically housed in the cistern, and the housing means has a communication path for communicating the sealed internal atmosphere with the outside air of the cistern. According to this structure, washing with water can be performed with a light operation. This is possible, and there is no problem even if it is installed inside the cistern.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.

Figure 2 shows how this device is installed in a toilet bowl, and the base 13 and sealing lid 14, which are installed into the inner wall of the cistern 2 through a through hole, constitute a storage means, and 15 is a manual lever. be. Note that the same members as in FIG. 1 are given the same numbers.

FIG. 3 is a sectional view, and FIG. 4 is a front view without a sealing lid for ease of understanding. The lever 10, the chain 11, and the rotating shaft 16 constitute a valve opening means. The rotating shaft 16 has an arm 17 . Further, the AC motor 18, a positioning cam 20 coupled to its shaft 19, an eccentric cam 21, and a first micro switch 22 which is turned on and off by rotation of the positioning cam 20 constitute electromagnetic driving means.
An arm 17 is mounted on the eccentric cam 21, and when the eccentric cam 21 makes one rotation, the arm 17 moves by an angle α. At this time, the lever 10 connected to the tip of the rotating shaft 16 moves up and down, opening the valve 12. The base 13 is installed and fixed in the through hole 24 of the cistern 2 by a nut 23. Reference numeral 25 is a movable rotary shaft that is coaxial with the rotary shaft 16 and is movable in the axial direction, and rotates at the same time as the rotary shaft 16 during rotation; 26 is a second micro switch that is turned on when the movable rotary shaft 25 moves; and 27 is a Move manual lever 15 to rotation axis 2
5, 28 is a blind plate, 29 is a spring that urges the moving rotation shaft 25 in the direction in which the manual lever 15 pops out, 30 is a gasket that maintains airtightness between the base 13 and the sealing lid 14, 31 is a sealing lid. 14 and the electric wire 8, and 32 is an O-ring that maintains the airtightness between the sealing lid 14 and the rotating shaft 16 and allows rotation of the rotating shaft. Further, the hermetically sealed internal atmosphere constituted by the base 13 and the sealing lid 14, which are storage means, is communicated with the outside air of the cistern through a communication path 33 provided via the moving rotation shaft 25 in this example.

FIG. 5 shows the simplest example of a control circuit for energizing the toilet flushing device of the present invention, and 34 is
AC power supply 35 is provided on the case 5 side, and the toilet seat 3
This is a flush switch that can be operated at any time while sitting on the machine.

In the above configuration, when the flush switch 35 is turned on, the AC motor starts rotating. At this time, the positioning cam also rotates and the first micro switch 22 is also turned on immediately, so even if the flush switch 35 is turned off, power to the AC motor is supplied via the first micro switch and continues to rotate. At this time, since the eccentric cam also rotates at the same time, the rotating shaft 16 is rotated by the angle α by the arm 17, and the lever 10 and chain 11 are lifted to open the valve 12, and the cistern 2
The water stored inside is discharged into the toilet bowl 1 for flushing. Once the valve 12 is opened, it remains open by itself until the water stored in the cistern 2 is completely discharged due to the water discharging force. When the motor 18 makes one revolution, the first micro switch 22 is turned off at the original position by the action of the positioning cam 20, so that the AC motor 18 is automatically turned off after one revolution and stops rotating.

When men want to wash their clothes with water after finishing their errands, they can press the manual lever 15 to turn on the second micro switch 26, supply power to the AC motor 18, and wash with water in the same way as in the case described above. can. Therefore, the water washing operation at this time can be performed with one touch.

At the time of a power outage, when the manual lever 15 is rotated in the same manner as a conventional manual lever, the lever 10, chain 11, and valve 12 are lifted up via the moving rotation shaft 25 and the rotation shaft 16, and water washing can be performed. but,
In this case, the manual lever operation cannot be done with a light one-touch operation, and as in the past, the valve 12
The operating force required to overcome the water pressure applied to the Therefore, with this configuration, flushing can be performed using an operation signal from the toilet seat side using the electromagnetic drive means, providing excellent convenience and cleanliness; There are only a few parts exposed to the toilet seat 3 and lid 4.
Furthermore, even though the electromagnetic drive means is inside the cistern, it is isolated from the high humidity atmosphere inside the cistern and communicated with the outside air of the cistern by the storage means. Therefore, there is no need to worry about coil breakage or electrical leakage due to corrosion, and it is highly reliable and safe. In addition, by pressing the manual lever, washing with water after men's errands can be performed with a single touch, making it easy for even the elderly and children to operate, and even when the electromagnetic drive means does not work during a power outage, the manual lever can be rotated. By doing this, you can wash with water at any time.

Note that when manual lever operation is not required, the manual lever 15, the moving rotation shaft 25, the second micro switch 26, the screw 27, the blind plate 28, etc. are unnecessary, and the communication port 33 is connected to the moving rotation shaft 25. It is also possible to provide the flush switch 35 on the base 13 side instead of through the toilet seat, and the flush switch 35 is not just an operation switch, but is configured with a switch that is turned on when the user stands up from the toilet seat, thereby enabling automatic flushing. Become. Further, a configuration in which the electric wire 8 can be drawn out from the through hole 24 side to the outside of the cistern is also possible, and the present invention is not limited to this embodiment.

Effects of the Invention As described above, the toilet flushing device of the present invention provides the following effects.

(1) Since the electromagnetic drive means is hermetically housed in the storage means and has a communication port that communicates the sealed internal atmosphere with the outside air of the cistern, the electromagnetic drive means is isolated from the high humidity atmosphere inside the cistern.
It is possible to maintain the same normal humidity as the outside air in the cistern.
Therefore, it is possible to prevent accidents such as corrosion of the electromagnetic drive means and disconnection of the coil or leakage of electricity, improving reliability and
Improves safety.

(2) Since the electromagnetic drive means is installed inside the cistern, there are fewer parts exposed outside the cistern, which eliminates the inconvenience of the toilet seat and lid not being able to stand up against each other, and the appearance is also good.

(3) Operability is improved because the valve is opened using electromagnetic drive means for flushing.
