Description

  The present invention relates to a tank device and a flush toilet equipped with the tank device.

  Conventionally, as shown in Patent Document 1, for example, in a flush toilet tank device, a drain valve device provided with a cylinder having an opening on a side surface around a drain valve has been used. According to such a drain valve device, by opening the drain valve in a state in which the opening of the cylinder is closed, the small washing mode in which a relatively small amount of washing water is supplied to the toilet and the opening of the cylinder are opened. By opening the drain valve in a state of being discharged, the drainage can be performed in two kinds of modes with different drainage amounts such as a large washing mode in which a relatively large amount of washing water is supplied to the toilet.

  When installing such a drain valve device, the drain valve device's drain valve is changed by changing the volume of the float so that a predetermined amount of flush water is discharged to the toilet body during large washing and small washing respectively. It was necessary to adjust the drain valve device such as adjusting the descending speed of the cylinder or changing the area of the opening of the cylinder.

JP-A-60-184133

  Here, the tank device in which the wash water is stored has various shapes such as a cross-sectional shape depending on a space in which it is installed. However, the lowering speed of the drain valve and the flow rate passing through the opening of the cylinder are easily affected by the tank shape, so even if the same drain valve apparatus is used, the drain valve apparatus for each tank apparatus having a different shape. It was necessary to make adjustments, and this adjustment was very time-consuming.

  The present invention has been made to solve the above-described problems of the prior art, and a predetermined amount of washing water is discharged even when a drain valve device is applied to a tank device having a different shape. An object of the present invention is to provide a tank device and a flush toilet that can reduce the trouble in adjusting the drain valve device.

In order to achieve the above object, the present invention is a tank device for storing cleaning water for cleaning a toilet body, a cleaning water tank for storing cleaning water for cleaning a toilet, and a bottom surface of the cleaning water tank. A drain outlet for supplying the cleaning water formed and stored in the cleaning water tank, and supplying the cleaning water to the toilet body by opening and closing the drain opening, and a standard specification adjusted for a specific cleaning water tank. The flush water tank has a shape different from that of the specific wash water tank, and the horizontal cross-sectional area at each height from the dead water level to the stop water level is almost the same as that of the specific wash water tank. It is characterized by the same shape.
According to the present invention configured as described above, since the horizontal cross-sectional area at each height from the dead water level to the still water level of the washing water tank is substantially equal to the specific washing water tank, Even if the washing water tank has a shape different from that of the specific washing tank, the same amount of washing water can be discharged. For this reason, even if the wash water tank has a shape different from that of the specific wash water tank, the discharge amount of the wash water is a predetermined amount in the tank valve equipped with the specific wash water tank. By doing so, this standard specification drain valve device can be applied to other wash water tanks having different shapes.

In the present invention, preferably, the drain valve device includes a cylinder body that is provided so as to surround a drain port of the tank apparatus and that has an opening at a side portion thereof, and a valve body that opens and closes the opening of the cylinder body.
According to the present invention configured as described above, since the amount of drainage is not easily affected by pressure loss of the toilet body, the standard drain valve device can be used for other wash water tanks having different shapes regardless of the type of toilet body. Can also be applied.

  Moreover, the flush toilet of this invention is equipped with the tank apparatus mentioned above, It is characterized by the above-mentioned.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the configuration of a tank apparatus according to an embodiment of the present invention will be described. FIG. 1 is a vertical sectional view showing a configuration of a tank apparatus 10 according to an embodiment of the present invention. The tank apparatus 10 is attached to the toilet bowl body to constitute a flush toilet. As shown in FIG. 1, the tank apparatus 10 includes an exterior tank 100, an interior tank 110 accommodated in the exterior tank 100, and an exterior tank 100. A lid 120 provided at the top, a water supply mechanism 130 for supplying water to the interior tank 110, a drain valve device 140 for opening and closing the discharge port of the interior tank 110, and an operation mechanism 150 for operating the drain valve device 140. Prepare.

  The exterior tank 100 is a pottery container having an open top, a water supply pipe hole (not shown) formed on the left side, a handle insertion hole (not shown) formed on the right side, and a bottom surface A drain pipe hole 100a formed at the center.

  The lid 120 is a ceramic member having a faucet (not shown) and a hand-washing bowl 121 formed on the upper surface, and is placed so as to cover the upper opening of the exterior tank 100. Hand washing water is supplied to the faucet from a water supply mechanism 130 described later.

  The interior tank 110 is a hollow resin container that opens upward, and has a tank body 111 having a drain port 111a at the bottom, and an annular cylindrical shape that extends downward from the periphery of the drain port 111a on the bottom surface of the tank body 111. Part 112. The interior tank 110 is inserted into the drain pipe hole 100a formed on the bottom surface of the exterior tank 100, and a nut 190 with a collar is tightened on the tubular section 112 from the outside of the exterior tank 100, thereby It is integrated. In the interior tank 110, cleaning water is supplied from the water supply mechanism 130 to a predetermined water level in a state where the drain port 111a on the bottom surface is closed by a valve of a drain valve device 140 described later. And if the valve body 142 of the drain valve apparatus 140 is open | released, the wash water stored inside will flow into the toilet bowl main body through the cylindrical part 112. FIG.

  The operation mechanism 150 transmits to the spindle mechanism 152 a handle mechanism 151 provided on the side of the exterior tank 100, a spindle mechanism 152 fixed to the upper center of the interior tank 110, and a rotational force applied to the handle mechanism 151. And a first ball chain 154, 155 having an upper end connected to the spindle mechanism 152 and a lower end connected to the drain valve device 140.

  The handle mechanism 151 includes a handle portion 156, a shaft portion 157 having one end connected to the handle portion 156 and the other end connected to the rotation transmission member 153, and a motor 158 attached to the shaft portion 157. The handle mechanism 151 is fixed to the exterior tank 100 with the handle portion 156 protruding from the exterior tank 100 to the outside.

  The handle portion 156 is a member that is integrally formed with the shaft portion 157 and is rotatable about the shaft portion 157 as a central axis, and is applied with a rotational force in a direction corresponding to the cleaning mode (large cleaning and small cleaning). The rotational force applied to the handle portion 156 is transmitted to the rotation transmission member 153 via the shaft portion 157.

The motor 158 rotates the shaft portion 157 according to various modes, generates a braking force against the force that closes the valve acting on the shaft portion 157, and controls the valve body 142 of the drain valve device 140 and the drainage amount adjustment valve 143. Control the speed and timing of opening and closing.
The spindle mechanism 152 includes a spindle 159 and a spindle support portion 160 that rotatably supports the spindle 159. The upper ends of the first and second ball chains 154 and 155 are connected to the spindle 159, and when a rotational force is transmitted from the handle mechanism 151 via the rotation transmission member 153, the first and second ball chains 154 and 155 are connected in accordance with the rotation direction. Only one ball chain 154 or both the first and second ball chains 154 and 155 are pulled up.

  The drain valve device 140 includes a cylinder 141 provided so as to surround the drain port 111a of the interior tank 110 and a valve body 142 that can close the drain port 111a of the interior tank 110. It is a valve device. The valve body 142 normally closes the drain port 111a of the interior tank 110, and opens the drain port 111a when the first ball chain 154 is pulled up. When the drainage port 111a is opened at one end, the valve body 142 receives buoyancy from the float 144, and continues to open the drainage port 111a until the water level in the interior tank 110 decreases to a predetermined height.

  An opening 141a is formed on the side surface of the cylinder 141, and a drainage amount adjustment valve 143 is attached to the opening 141a. The drainage amount adjustment valve 143 normally opens the opening 141a of the cylinder 141, and closes the opening 141a of the cylinder 141 when the second ball chain 155 is pulled up. In addition, when the state in which the ball chain 155 is pulled up second after the start of drainage is not maintained, only a part of the opening 141a is closed, and the second ball chain 155 is pulled up during drainage. When the state is maintained, a state in which the entire surface of the opening 141a of the cylindrical body 141 is closed is maintained.

  With such a configuration, when only the first ball chain 154 is pulled up, the opening 141a is opened, and therefore, a portion above the upper edge of the cylinder 141 in the interior tank 110, the cylinder 141 The cleaning water inside and outside the cylinder 141 is supplied to the toilet body (large cleaning mode).

  Further, when the first and second ball chains 154 and 155 are pulled up, a part of the opening 141a is closed, and therefore, a portion above the upper edge of the cylinder 141 in the interior tank 110, A part of the washing water inside the cylinder body 141 and outside the cylinder body 141 is supplied to the toilet body (small washing mode). That is, in the small washing mode, a small amount of washing water is supplied to the toilet body as compared with the large washing mode.

In addition, when the motor 158 of the operation mechanism 150 is set to eco-cleaning, the state where the second ball chain 155 is pulled up is maintained even after the drainage is started, and the entire surface of the opening 141a is closed. The portion of the tank 110 above the upper edge of the cylinder 141 and the cleaning water inside the cylinder 141 are supplied to the toilet body (eco-small cleaning mode). That is, in the eco small cleaning mode, a smaller amount of cleaning water is supplied to the toilet body as compared with the small cleaning mode. Thus, the water level in the state where drainage is completed in each cleaning mode is referred to as dead water level.
In each of the above cleaning modes, the buoyancy of the float 144 of the drain valve device 140, the area of the opening 141a, the motor 158, and the like are adjusted according to the internal tank 110 so that a predetermined amount of flush water is discharged.

  The water supply mechanism 130 is connected to a water supply pipe (not shown) extending from the outside through a water supply pipe hole of the exterior tank 100, and cleaning water is supplied through this water supply pipe. The water supply mechanism 130 switches between opening and closing of the water supply port according to the water level, and when the drain valve device 140 is opened and the water level falls below a predetermined depth, water supply to the interior tank 110 is started, and the drain valve device 140 is closed. When the cleaning water is stored in the interior tank 110 again to a predetermined depth, the water supply is stopped. In this way, the water level in a state where water supply is stopped is referred to as a still water level.

  The tank device 10 has a different shape depending on the shape of the chamber in which it is installed. Even if the tank apparatus 10 has a different shape, a predetermined amount of drainage must be drained in each cleaning mode. However, the amount of water drained from the tank device 10 is easily affected by the shape of the interior tank 110 for reasons such as a change in head pressure. For this reason, even if the same drain valve device 140 as the drain valve device 140 (hereinafter referred to as a standard drainage device) of the tank device 10 that has already been adjusted to have a predetermined drainage amount as described above, When the shape of 110 is different, the drain valve device 140 has to be adjusted so that a predetermined amount of drainage is discharged to the toilet body in each washing mode for each of the interior tanks 110 having different shapes.

  On the other hand, in this embodiment, when using the drain valve device 140 of the standard specification in the tank device 10 having the interior tank 110 having a different shape, the interval between the dead water level and the still water level in the interior tank of each tank device. The cross-sectional areas of the interior tanks are substantially constant, and the cross-sectional areas of the interior tanks are substantially equal to each other.

  2 to 4 show interior tanks 110a, 110b, and 110c having different cross-sectional shapes to which the same drain valve device 140 is applied. In each figure, (A) is a plan view and (B) is a vertical section. FIG. 5 to 7 are horizontal cross-sectional views at the still water level of the interior tanks 110a, 110b, and 110c, the dead water level for eco-cleaning, the dead water level for small washing, and the dead water level for large washing, respectively. The elliptical interior tank 110a shown in FIGS. 2 and 5 is the interior tank 110a of the tank apparatus 10 provided with the standard drain valve device 140 described with reference to FIG.

  As shown in FIGS. 2 to 4, these interior tanks 110 a, 110 b, and 110 c have an elliptical shape, a rectangular shape, and a square sectional shape, respectively, and are different in shape from each other. In addition, the internal tanks 110a, 110b, and 110c have a substantially constant cross-sectional area from the bottom surface to the water stoppage level, and the internal tanks 110a, 110b, and 110c having different cross-sectional shapes have substantially the same cross-sectional area.

  The rectangular and square interior tanks 110b and 110c are attached with the same drain valve device as the drain valve device 140 which is a standard adjusted with respect to the elliptical interior tank 110a. For this reason, the dead water level in each interior tank 110a, 110b, 110c becomes equal, and furthermore, since the amount of drainage in each cleaning mode is constant, the water stop level is also substantially equal.

  In each of the interior tanks 110a, 110b, and 110c, the flow rate of the cleaning water discharged from the drain port 111a is easily affected by the head pressure and the pressure loss in the toilet body. In contrast, as described above, the interior tanks 110a, 110b, and 110c shown in FIGS. 2 to 4 have the same level of the water-stopping water level. The pressure is approximately equal. Furthermore, the drainage valve device 140 having the cylindrical body 141 surrounding the drainage port 111a of the interior tank 110 as used in the present embodiment is such that the flow rate of the wash water discharged influences the pressure loss in the toilet body. It is hard to receive. For this reason, the flow rates of cleaning water at the start of drainage in the interior tanks 110a, 110b, and 110c having different cross-sectional shapes are equal. Furthermore, since the internal tanks 110a, 110b, and 110c have the same cross-sectional area, the water level also decreases at the same speed. Therefore, until the drain valve device 140 closes the drain port 111a in each cleaning mode, the same flow rate is discharged regardless of the shape of the interior tanks 110a, 110b, 110c, and the amount of drainage is also equal.

  Therefore, the interior tanks 110b and 110c shown in FIGS. 3 and 4 are adjusted so that a predetermined amount of cleaning water is discharged in each cleaning mode, which is used in the substantially elliptical interior tank 110a shown in FIG. Since the standard-specific drainage device 140 is applied, a predetermined amount of cleaning water is also discharged from these internal tanks 110b and 110c in each cleaning mode.

  That is, when the same drain valve device 140 is applied to a plurality of interior tanks 110a, 110b, and 110c having different cross-sectional shapes, the drain valve device 140 is configured such that a predetermined amount of washing water is discharged from any one of the interior tanks. Therefore, by applying this standard specification drain valve device 140 to other interior tanks, a predetermined amount of washing water is drained, and it is necessary to adjust the drain valve device 140 for each interior tank. Disappear.

  In particular, as in this embodiment, the drain valve device 140 having the cylindrical body 141 around the drain port 111a of the interior tank 110 is less susceptible to pressure loss in the toilet body. For this reason, even if the pressure loss of the toilet bowl body is different, if the cross-sectional area of the interior tank 110 is approximately equal, the amount of flush water becomes substantially equal by applying the same drain valve device 140.

  In the above embodiment, the case where the cross-sectional area from the bottom surface of the interior tank 110 to the still water level is the same has been described. However, the present invention is not limited to this. By applying the drain valve device 140, the amount of wash water to be drained becomes substantially equal.

  In the above embodiment, the drain valve device 140 including the cylindrical body 141 around the drain port 111a is described as the drain valve device. However, the present invention is not limited thereto, and other valve mechanisms such as a flapper valve may be used. Even when the drain valve device is applied, the amount of washing water becomes constant by equalizing the cross-sectional areas from the dead water level to the still water level.

  However, when applying the drain valve device 140 that does not include the cylinder body 141 such as a flapper valve, it is desirable that the pressure loss of the toilet body to which the tank device having a different cross-sectional shape is connected is substantially constant.
