Description

  The present invention relates to a hand-washed row tank facility in which a hand-washing basin is provided on the upper portion of the row tank cover, and more particularly to a hand-washed row tank facility in which at least the front portion of the row tank cover and the hand-washing basin can be raised and lowered.

  A Western-style toilet facility in which a low tank for storing toilet flush water is installed on the rear upper surface of a Western-style toilet, and this low tank is covered with a low tank cover is widely used. It is also well known to provide a hand basin on the upper part of the raw tank cover.

  In order to reduce the noise of water splashing in the low tank from the outlet of the hand wash basin of the low tank cover, a cover is provided on the low tank cover, and the water that has fallen from the hand basin is received by this cover so that it flows along the inner wall of the low tank. A constructed hand-washed low tank facility is described in JP-A-11-324058.

  A hand-washed low tank facility that allows the low tank cover to be lifted and carefully cleaned between the front of the low tank and the upper surface of the Western-style toilet is also well known (for example, Japanese Patent Application Laid-Open No. 2003-155766), and has already been widely marketed.

  If water is discharged from the hand-washing water discharge pipe when the hand-washing bowl rises, there is a risk that water that has dropped from the outlet of the hand-washing bowl will be scattered outside the low tank.

Japanese Patent Application Laid-Open No. 2003-155766 describes that a low tank cover is detected by a sensor so as not to perform a flush operation (flowing flush water from a low tank to a toilet). If the flush operation is not performed, the low tank ball tap will not be opened, so water will not be discharged from the hand wash water discharge pipe.
JP-A-11-324058 JP 2003-155766 A

  As described in Japanese Patent Application Laid-Open No. 2003-155766, it is necessary to use a sensor or the like to detect the rising of the low tank cover so as not to perform the flush operation and as a result not to discharge water from the handwash water discharge pipe. It is expensive.

  An object of the present invention is to provide a hand-washing low tank facility in which water outflow from a hand-washing basin surely flows into the raw tank even when water is discharged from the hand-washing water discharge pipe when the hand-washing basin is raised.

  The low tank facility for hand-washing of the present invention (Claim 1) has a low tank for storing toilet flush water, a low tank cover for covering the low tank, an upper portion of the low tank cover, and a water outlet at the bottom. A hand basin, a water drop guide member connected to the outlet, and a water receiving member installed on the row tank for receiving the water flowing down from the guide member and flowing it into the row tank In the low tank facility with hand wash in which at least the front part of the low tank cover and the hand basin can move up and down, the water receiving member is provided with a receiving part into which the guide member is inserted, and the hand basin is raised. In some cases, the lower end of the guide member is positioned lower than the lowest position of the upper end of the receiving portion.

  The low tank facility for hand-washing according to claim 2 is characterized in that, in claim 1, the receiving part is surrounded by a wall-like part, and when the hand-washing bowl rises, the lower end of the guide member is the lowest of the upper end of the wall-like part. It is characterized by being positioned lower than the place.

  The hand-washing low tank facility according to claim 3 is characterized in that, in claim 1 or 2, the receiving part has a relatively high peripheral part and a concave part recessed from the peripheral part, and the guide member is the concave part. The lower end of the guide member is located in the recess when the hand basin is raised.

  The low tank facility for hand-washing of the present invention is configured so that water can be discharged from the hand-washing water discharge pipe even when the hand-washing bowl rises. When water is discharged from the hand-washing water discharge pipe when the hand-washing basin is raised, water flows from the hand-washing basin outlet through the guide member to the receiving portion. The guide member enters the receiving portion, and the lower end of the guide member is lower than the lowest position of the upper end of the receiving portion. For this reason, the water flowing out from the guide member always falls into the receiving portion, is prevented from flowing out of the receiving portion, and surely flows into the low tank.

  In the low tank facility for hand-washing according to claim 2, the receiving part is surrounded by a wall-like part, and the lower end of the guide member is lower than the lowest position of the upper end of the wall-like part. Yes. For this reason, the water that has flowed down from the guide member and hit the bottom of the receiving portion is also difficult to jump out of the receiving portion.

  In the low tank equipment for hand-washing of Claim 3, the guide member is inserted in the recessed part provided in the receiving part, and the lower end of a guide member is arrange | positioned in a recessed part even when a hand basin raises. For this reason, the effluent water from the hand-washing basin surely flows into the low tank through the recess.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a side view of a hand-washed low tank facility according to the embodiment, and FIG. 2 is a longitudinal sectional view of the vicinity of a hand-washing bowl of the hand-washed raw tank facility. 1 and 2, (a) shows the time when the low tank cover is not raised, and (b) shows the time when the low tank cover is raised. FIG. 3 is a sectional view taken along line III-III in FIG. 2 (a), and FIG. 4 is a sectional view taken along line IV-IV in FIG. 2 (b).

  As shown in FIG. 1, a low tank 2 and toilet equipment (not shown) such as a hot water washing apparatus are installed on the rear upper surface of the Western-style toilet 1, and a low tank cover 3 is installed so as to cover them. A hand-washing basin 4 is placed on the upper portion of the low tank cover 3. A toilet seat 5 and a toilet lid 6 are attached to the lower part of the front surface of the low tank cover so as to be rotatable in the up-down direction. A hand wash water discharge pipe 7 for discharging hand wash water into the hand wash bowl 4 is provided upright from the rear edge of the hand wash bowl 4.

  The low tank 2 is fixedly installed on the rear upper surface of the Western-style toilet 1. A float valve (not shown) for discharging toilet flush water is provided at the bottom of the low tank 2, and a ball tap (not shown) for water supply is provided at the top. The water discharge side of the ball tap is branched into a water supply pipe (not shown) to the low tank 2 and a water supply pipe 8 to the hand basin 4. The water supply pipe 8 is connected to the hand washing water discharge pipe 7. Details of this connection structure will be described later.

  In this embodiment, the low tank cover 3 is divided into a cover front half 3F and a cover rear half 3R. As shown in FIG. 1 (b), the cover front half 3F can be moved up and down with respect to the rear upper surface of the Western-style toilet 1 by an elevating device (not shown). In contrast, it is fixedly installed so that it cannot be raised or lowered. In the present invention, the configuration of the lifting device is not particularly limited, and various lifting devices such as a cylinder mechanism, a spring, or a motor as a power source can be employed.

  The hand basin 4 is connected to the upper part of the cover front half 3F and moves up and down integrally with the cover front half 3F. The water supply pipe 8 is fitted into the rear end side (upstream side) of the hand-washing water discharge pipe 7 in a watertight manner and slidable in the insertion / extraction direction. The depth of insertion of the water supply pipe 8 into the hand wash water discharge pipe 7 is larger than the vertical movement width of the hand wash bowl 4 when the hand wash bowl 4 is at the lower limit. Therefore, even when the hand-washing basin 4 moves to the upper limit, the water supply pipe 8 does not come out of the hand-washing water discharge pipe 7, and water can be supplied from the water supply pipe 8 to the hand washing water discharge water pipe 7 at all times.

  In addition, the connection structure of the water supply pipe 8 and the hand-washing water discharge pipe 7 is not limited to this. For example, both may be connected by a flexible pipe or the like.

  Near the center of the bottom of the hand-washing basin 4, an outlet 9 for water discharged from the hand-washing water discharge pipe 7 is provided. Further, a water drop guide member 10 connected to the outflow port 9 protrudes downward from the bottom lower surface of the hand basin 4. In this embodiment, the guide member 10 is a pipe whose upper end is continuous with the outlet 9.

  A lid 11 is mounted on the upper portion of the row tank 2. The lid 11 is provided with a water receiving member 12 for receiving the water flowing down from the guide member 10 and allowing it to flow into the low tank 2. The water receiving member 12 has a receiving portion 13 that receives water flowing down from the guide member 10 and a wall-like portion 14 that surrounds the receiving portion. In this embodiment, the vicinity of the center of the receiving portion 13 (near the bottom of the guide member 10) is a recess 15 that is recessed from the periphery. A water discharge port 16 communicating with the inside of the raw tank 2 is provided on the side surface of the recess 15 (the front side surface in this embodiment).

  Note that the bottom of the recess 15 is an inclined surface that slopes down toward the discharge port 16. In addition, in order to prevent the water flowing out from the guide member 10 from splashing upward as much as possible when it falls to the bottom of the concave portion 15, a large number of chevron ridges (unevenness) are formed on the bottom. Yes.

  In this embodiment, as shown in FIGS. 2 (a) and 3, the guide member 10 is inserted into the recess 15 when the hand basin 4 is at the lower limit. Further, as shown in FIGS. 2 (b) and 4, the guide member 10 has a lower end that is still lower than the lowest part of the upper edge of the wall-like portion 14 even when the hand-washing basin 4 moves to the upper limit. Is the length located at the lower height.

  In the hand-washed low tank facility having such a configuration, when the flush device (not shown) is flushed, the float valve of the low tank 2 is opened, and the stored water in the low tank 2 is discharged into the Western-style toilet 1 as toilet flushing water. The When the water level in the low tank 2 is lowered by this discharge, the ball tap is opened and water is supplied into the low tank 2. At this time, a part of the water from the ball tap is supplied to the hand washing water discharge pipe 7 through the water supply pipe 8, and the hand washing water is discharged from the hand washing water discharge pipe 7 into the hand washing bowl 4. This hand washing water flows from the outlet 9 through the guide member 10 to the receiving portion 13 of the water receiving member 12.

  In this hand-washing low tank facility, the guide member 10 is inserted into the recess 15 when the hand-washing basin 4 (that is, the cover front half 3F) is at the lower limit. Therefore, the water that has flowed out from the guide member 10 always falls into the recess 15, and the scattering and outflow of water to the outside of the water receiving member 12 are reliably prevented.

  Further, even when the hand basin 4 is in the ascending limit, the lower end of the guide member 10 is located at a lower level than the lowest part of the upper edge of the wall-like part 14 surrounding the receiving part 13, so this The water that flows out from the guide member 10 always falls into the receiving portion 13, and this water is prevented from scattering or flowing out of the wall-shaped portion 14.

  Thereafter, this water flows into the low tank 2 from the discharge port 16 and is stored as the next toilet flushing water.

  In the present invention, the lower end of the guide member 10 may be positioned in the recess 15 of the water receiving member 12 even when the hand basin 4 moves to the upper limit. With this configuration, even if the flushing operation is performed with the hand basin 4 positioned at the ascending limit, the water that has flowed out of the guide member 10 always falls into the recess 15 and is scattered around the water. And spills can be reliably prevented.

  The above embodiment shows an example of the present invention, and the present invention is not limited to the above embodiment.

  For example, in the embodiment described above, only the front half 3F and the hand basin 4 of the row tank cover 3 are lifted and lowered, but the entire cover is lifted and lowered like the row tank cover 3A of FIG. May be. FIG. 5 (a) shows the cover 3A when it is not lifted, and FIG. 5 (b) shows the cover 3A when it is lifted. The other structure of the low tank facility with a hand-washing of FIG. 5 is the same as that of the low tank facility with a hand-washing of FIGS.

  In the above embodiment, the water receiving portion from the guide member has a box-like shape having a flat bottom portion and a wall upper portion surrounding the flat bottom portion, but the shape of the receiving portion is limited to this. It is not a thing. The receiving part may be, for example, a funnel.

It is a side view of the low tank equipment with a hand-washing which concerns on embodiment. It is a longitudinal cross-sectional view of the handwashing bowl vicinity of the low tank equipment with a handwash of FIG. It is sectional drawing which follows the III-III line of FIG. It is sectional drawing which follows the IV-IV line of FIG. It is a side view of the low tank equipment with a hand-washing which concerns on another embodiment.
