Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage socket that is connected between a siphon trap of a flush toilet and a discharge pipe outside the toilet and guides wash water to the discharge pipe, a flush toilet having a siphon trap, and a flush toilet having the drain socket. .
[0002]
[Prior art]
In this type of flush toilet, efficient induction of siphon action is required. For example, in the flush toilet described in JP-A-8-326136, a drainage receiving surface is provided on the pipe of the drainage socket that is installed to change the direction of the water flow, thereby causing a temporary retention of the washing water. As a result, a technique has been proposed in which a siphon tube whose pipe line is full is formed to efficiently induce siphon action.
[0003]
[Problems to be solved by the invention]
  By the way, the siphon action disappears when the siphon tube is not filled with water (wash water) due to air ingress, flow rate reduction, or the like. In the above-mentioned publication, when the amount of washing water in the toilet bowl decreases and the amount of washing water flowing to the drain socket decreases, the amount of water flowing in the direction that changes direction on the drain receiving surface is reduced. Therefore, the degree of change in the direction of the water flow is reduced, and the wash water flows directly into the discharge pipe outside the toilet. In this case, the occupation area occupied by the washing water in the pipe cross section is reduced, so that air entry from the downstream is likely to occur andTheIt cannot be maintained and the siphon action is lost. In general, dirt (toilet paper, floating diarrheal stool, etc.) floating in the accumulated water in the ball is sucked into the trap and discharged in the latter half of the siphon. For this reason, in the prior art in which the siphon is likely to disappear at the end of the siphon that causes a decrease in the flow rate as described above, these floating wastes may not be completely sucked and discharged.
[0004]
The present invention has been made to solve the above-described problems, and an object thereof is to increase the suction efficiency of the accumulated water in the ball part at the end of the siphon.
[0005]
[Means for solving the problems and their functions and effects]
  In order to solve the above problems, the drain socket of the present invention is
  A drainage socket having a socket line that is connected between the siphon trap of the flush toilet having a siphon trap and a discharge pipe outside the toilet, and that guides wash water that has passed through the siphon trap to the discharge pipe,
  Prior to the end of the siphon when the siphon action that occurs when the siphon trap is full is over, a part of the wash water passing through the socket pipe or the siphon trap is stored, and the stored wash water is stored. The socket pipe has adjustment means for replenishing the socket pipe passage washing water at the end of the siphon and adjusting the amount of washing water passing through the socket pipe,
  The adjusting means is,in frontA recess recessed from the socket conduit to the outside of the conduit is provided in the direction of the conduit of the socket conduit, and a portion of the passing wash water enters and stores in the recess before the end of the siphon.

  The recess takes the socket conduit.A screw formed in a continuous spiralThe concessionCausing a spiral flow in the wash water in the spiral recess
  It is characterized by that.
[0006]
  In the drain socket according to the present invention having the above-described configuration, the amount of passage washing water in the socket pipe is increased and adjusted at the end of the siphon, so that the area occupied by the passage washing water in the pipe cross section is not reduced. Therefore, air entry from the downstream can be suppressed,TheCan be maintained. For this reason, even at the end of the siphon, the suction efficiency of the ball portion stored water can be increased by the siphon action, and the reliability of suction and discharge of the floating waste can be increased.
[0008]
  The drainage socket of the present invention having the above configuration.KeyHandThe stage isThe stored wash water is replenished to the wash water passing through the socket line at the end of the siphon.SoAdjust the amount of washing water passing through the socket pipe with supplementary washing water and adjustTheIt is possible to maintain and improve the suction efficiency of the ball part stored water at the end of the siphon, and further improve the reliability of suction and discharge of floating waste.
[0009]
  in this case, DoubleIf the cleaning water is replenished at several places, the above-described siphon tube maintenance by the replenishing cleaning water can be ensured.
  In addition, a siphon triggering mechanism is provided in the drainage socket or the siphon trap of the toilet bowl to induce a siphon action by causing a temporary stagnation of the passing wash water., A storage hand that stores a part of the wash water that has flowed from the location where the wash water staysSteps can also be provided. In this way, since the washing water can be replenished near the siphon action inducing portion, the siphon tube can be maintained more reliably and the reliability can be improved.
[0010]
  Also beforeRecordStores a part of the washing water that passes through the socket pipe or siphon trap before the end of the IphoneBecauseReplenishment wash water can be procured from passing wash water, i.e. wash water supplied to the toilet bowl for toilet flushing. In addition, no special water channel system is required for replenishing the washing water. Therefore, the amount of cleaning water to be used is not increased, and the configuration can be simplified.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, an embodiment of the flush toilet of the present invention will be described below. FIG. 1 is an explanatory view showing a longitudinal section of a siphon jet flush toilet 10 according to an embodiment of the present invention. This siphon jet flush toilet 10 causes siphon action by jetting water from a jet jet hole 22 to be described later with the cleaning.
[0016]
As shown in FIG. 1, the flush toilet 10 includes a ball portion 20 that receives filth. The peripheral wall of the ball portion 20 includes a water-covering surface 23 that is in contact with the stored water RW even when the flush toilet 10 is not washed, and an exposed surface 24 that is not in contact with the accumulated water RW when the flush toilet 10 is not washed.
[0017]
The recess 26 at the bottom of the ball portion 20 has a jet ejection hole 22 almost opposite to the suction port 25 of the siphon trap conduit. The jet ejection hole 22 is connected to a jet water supply hole 45 which is a cleaning water inlet to the hole via a jet water supply path 46 which is curved so as to surround the ball portion 20 inside the toilet. The washing water ejected from the jet ejection hole 22 enters the siphon trap after the suction opening 25 without causing energy loss due to the positional relationship between the ejection hole and the suction opening of the trap. As a result, the pipe can be filled up in the early stage and the siphon action can be induced early.
[0018]
A flush water tank 310 is installed behind the flush toilet 10 in order to supply flush water to the ball unit 20 when flushing the toilet bowl. The toilet bowl 10 includes a cleaning water supply hole 40 through which tank cleaning water flows through the drain pipe 346, and has a cleaning water supply channel 41 that is a flow path of cleaning water below the toilet water supply hole 40. The washing water supply passage 41 defines a staying portion 41 a as a space interposed between the jet water supply 46 for jetting washing water to the ball portion and the lower end of the drain pipe of the washing water tank 310. Then, the cleaning water discharged from the drain pipe flows into the staying portion 41a during the cleaning, and this inflow cleaning water is jetted from the jet jet hole 22 through the jet water supply hole 45 and the jet water supply passage 46. Further, after the staying portion 41a is full, the washing water in the staying portion flows out to the rim water supply passage 43 through the branch hole 42 above the staying portion, and from the rim ejection hole 44 formed at the lower end of the rim portion 21. Erupted.
[0019]
Next, a discharge mechanism including a siphon trap will be described. As shown in the figure, the siphon trap is connected to a connection path 31 that curves in a diagonally upward direction from a suction port 25 that opens in a recess 26 serving as a filth reservoir. It comprises an ascending path 32 that curves in the direction and a descending path 33 that curves downward from the lateral direction.
[0020]
The descending path 33 has, at its end portion, an expanded portion 33a with an expanded pipe diameter and an end throttle portion 33b with an opening area narrower than that of the expanded portion. Therefore, the descending path 33 temporarily retains the washing water that passes through the expansion part 33a and the end throttling part 33b, so that the descending path 33 itself induces siphon action. The descending path 33 is connected to a drain pipe 90 that is set up from a toilet floor surface FL at a toilet installation location via a resin drain socket 70 at its end.
[0021]
These flow paths are formed integrally with the flush toilet 10 which is a pottery by taking this flow path shape into a plaster mold or a resin mold, but the flow path is formed by a member different from the flush toilet 10. It is also possible. For example, all or some of these flow paths may be formed of other members such as resin and connected to the suction port 25.
[0022]
The drain socket 70 is formed on a toilet floor surface FL and is formed with a socket main body 71 fixed to the toilet floor surface with bolts and the like, and a socket pipe 72 that guides the washing water passing through the siphon trap to the drain pipe 90. And a pipe line forming body 73 to be used. The pipe line forming body 73 has a spiral recess 74 that spirally surrounds the socket pipe line 72. In this case, the socket pipe line 72 has substantially the same diameter as the above-described end throttle portion 33b.
[0023]
The socket body 71 includes a descending path fitting part 71a into which the end of the descending path 33 enters the upper end, and a drain pipe fitting part 75 into which the upper end of the drain pipe 90 enters from below. The drain pipe fitting portion 75 positions the drain socket 70 with respect to the drain pipe 90 by fitting the drain pipe 90. Since the end of the pipe line forming body 73 is located below the upper end of the drain pipe 90, the wash water that has passed through the pipe line forming body 73 is unlikely to leak from the upper end of the drain pipe 90.
[0024]
Both the socket main body 71 and the pipe line forming body 73 of the drain socket 70 described above are resin-molded products, and the flush toilet 10 is separate from the descending path 33 in detail. May be integrated with a siphon trap). In this way, when integrated with the descending path 33, a pipe line such as the socket pipe line 72 is connected to the descending path 33 together with the spiral recess 74 with the end throttling part 33b sandwiched between the expansion part 33a and the toilet bowl. That's fine. In addition, the siphon trap of the flush toilet 10 does not have a siphon inducing mechanism such as the end throttling portion 33b, and a drain socket 70 connected to the siphon trap has a siphon inducing mechanism such as the end throttling portion 33b, a socket line 72, and It is also possible to have a pipe line forming body 73. In order to make the socket body 71 and the pipe line forming body 73 into a resin molded product, it can be made of the same vinyl chloride resin as the drain pipe 90, as well as ABS resin, PP (polypropylene), PE (polyethylene), PPS (polyphenylene sulfide). ), MA (acrylic), POM (polyacetal) and other various resins can be used.
[0025]
As shown in the figure, in the flush toilet 10 before the washing operation, the accumulated water RW accumulates at the height of the normal water level line WL in the connection path 31, the ascending path 32, and the ball portion 20. This stored water RW prevents the backflow of odors and the entry of pests from the drainage mechanism to the ball unit 20.
[0026]
The accumulated water RW includes water accumulated in the ball portion 20 up to the suction port 25 (hereinafter, this water is referred to as ball portion accumulated water or sealed water), a connection path 31 and a rising path 32 after the suction port 25. Water (hereinafter, this water is referred to as “reserved water in the flow path”) and water stored in the lower portion of the retention portion 41a of the flush toilet 10 and the jet water supply passage 46 (hereinafter, this water is referred to as “jet water storage”). As shown in FIG. 1, the accumulated water in the flow path is collected only at one place from the connection path 31 to the ascending path 32 among the sewage flow paths including the connecting path 31, the ascending path 32, and the descending path 33. . In addition, “sewage” refers to water that is contaminated by mixing filth such as urine and urine and paper.
[0027]
The height of the normal water level line WL is determined by the height of the weir 34 which is the highest position below the inner wall of the ascending path 32. Therefore, as shown in FIG. 1, since the lower part of the retention part 41a of the flush toilet 10, the jet water supply hole 45, and the jet water supply path 46 are below the weir 34, in the stationary state of the flush toilet 10, In the lower part of 41a and the jet water supply path 46, jet water is collected at the above-described water level. If the height of the weir 34 is lowered, the water level of the accumulated water RW is also lowered, and the amount of the ball portion accumulated water, the accumulated water in the flow path, and the zet accumulated water is also decreased.
[0028]
A mechanism for discharging sewage and filth by the drainage mechanism configured as described above will be described. When the cleaning water is discharged from the cleaning water tank 310, the discharged cleaning water first flows into the staying portion 41a, and the jet energy of the jet water supply passage 46 is used as the kinetic energy as the potential energy to store the ball portion of the ball portion 20. Pour into water (sealed water). As a result, the washing water jet from the jet jet hole 22 toward the trap is started, and thereafter, the discharge washing water itself continues from the jet jet hole 22 with the above energy while the washing water is continuously discharged. And then erupted. In the early stage of the progress of the jetting operation, the staying portion 41a is replaced with the discharge washing water. After the substitution is completed, the discharge washing water is jetted from the rim jet hole 44 through the branch hole 42.
[0029]
When the cleaning water is ejected to the ball portion 20 in this way, the water level of the ascending path 32 rises, and a bent part (hereinafter referred to as a bent part) from the ascending path 32 to the descending path 33 becomes full. Then, the washing water passes through the descending path 33, and at the time of the passage, the washing water is temporarily stored in the extended portion 33a at the descending path end, and the trap pipe is filled with the washing water. A siphon tube is formed. And a pressure difference arises between the washing water of this siphon tube, and the stored water of the ball | bowl part 20, and the drawing-in force to a downward direction arises. Due to this pulling force, the cleaning water (sewage) filled in the siphon trap (in the ascending path 32 and the connection path 31) and the cleaning water (sewage) in the ball are introduced into the drain pipe 90 together with the filth. Thus, siphon action is induced.
[0030]
Next, the behavior of the washing water after inducing siphon action will be described. FIG. 2 is an explanatory diagram for explaining the passage of washing water through the siphon trap and the socket pipe line 72.
[0031]
The washing water that flows due to the induction of the siphon action passes through the socket pipe 72 in a flow that attempts to pass through the socket pipe 72 as it is through the expanded portion 33a, as indicated by a white arrow in FIG. At the same time, a part of the washing water enters the spiral recess 74 surrounding the socket pipe 72 and is stored. And the washing water of this spiral recess 74 flows down spirally within this spiral recess 74 as shown by a dotted line in the figure. Alternatively, the washing water of the spiral recess 74 flows down from the opening of the recess due to its own weight, and merges with the washing water of the white flow in the figure.
[0032]
When a predetermined amount of the cleaning water supply from the cleaning water tank 310 and the ejection of the cleaning water from the ejection holes are almost finished, and the siphon end, the amount of the cleaning water that reaches the socket pipe line 72 through the siphon trap decreases. In this state, as shown in FIG. 2 (b), the flow rate of the washing water in a flow that attempts to pass through the socket pipe 72 as it is (hereinafter, this washing water is referred to as passing washing water for convenience) decreases. However, there is cleaning water in the spiral recess 74, and this cleaning water flows spirally along the spiral recess 74 or merges with the passing cleaning water. It becomes water. For this reason, the flow volume of the whole washing water which passes the middle of the socket pipe line 72 or its terminal is increased. Accordingly, the area occupied by the washing water in the pipe cross section of the socket pipe 72 is larger than that of the existing one that does not have the spiral recess 74, so that the air entry from the drain pipe 90 side is wide. It can be suppressed by the washing water present in the area. As a result, even at the end of the siphon where the flow rate is reduced, the siphon tube can be maintained for a long time, so that the suction efficiency of the ball pool water at the end of the siphon and the reliability of suction and discharge of floating waste can be improved. .
[0033]
Further, the replenishment of the wash water from the spiral recess 74 to the passing wash water is performed in the spiral recess 74 of each stage. Accordingly, the cleaning water can be reliably supplied to the passing cleaning water, so that the siphon tube can be reliably maintained. For this reason, it is possible to further improve the reliability of improving the suction efficiency of the ball portion stored water at the end of the siphon and the reliability of suction and discharge of the floating waste.
[0034]
In addition, since the spiral recess 74 is provided from directly below the throttle portion 33b of the connection path 31 that causes siphon induction, cleaning water can be supplied near the siphon action induction location. For this reason, the siphon tube maintenance can be made more reliable and the reliability can be improved.
[0035]
Moreover, since a part of the passing wash water is guided to the spiral recess 74 and used as the replenishment wash water, a special water channel system for replenishing the wash water is not required. Therefore, the total amount of cleaning water used for toilet cleaning is not increased, and the configuration can be simplified.
[0036]
Furthermore, since the spiral recess 74 generates a spiral flow of the cleaning water, the cleaning water swirls around the socket pipe 72. Accordingly, since the swirling washing water can also suppress the air ingress from the drain pipe 90 side, the reliability of the suction efficiency improvement at the end of the siphon and the reliability of the suction and discharge of floating waste can be further enhanced.
[0037]
In this embodiment, the spiral recess 74 in which the socket conduit 72 is recessed is used. However, a spiral plate body may be inserted into and attached to the socket conduit 72.
[0038]
Next, a modification of the above embodiment will be described. FIG. 3 is an explanatory view for explaining a drain socket 70 of a modified example. As shown in the figure, the drainage socket 70 of this modification has an annular recess 74a that is recessed outwardly in a skirt shape at appropriate intervals in the socket conduit 72. Then, a part of the passing washing water is temporarily stored in each annular recess 74a, and the washing water is replenished to the passing washing water by its own weight. For this reason, even in this modification, the washing water is merged with the passing washing water of the socket pipe line 72 from the respective annular recesses 74a as described above, so that the above-described effects can be achieved.
[0039]
Next, another embodiment will be described. FIG. 4 is an explanatory diagram for explaining the drain socket 170 of the second embodiment. As shown in the figure, a drain socket 170 of this modification has a socket body portion 171 for fixing the floor surface, and an upstream socket conduit 172 and a conduit for guiding the passing wash water to the drain pipe 90 therein. A formed body 173 is provided eccentrically. The drain socket 170 has a step 175 facing the lower end of the pipe formation body 173 that forms the upstream socket pipe 172, and a storage chamber 176 that surrounds the pipe formation 173 above the step. Is provided. Both the upstream socket pipe line 172 and the downstream socket pipe line 174 have substantially the same diameter as the end throttle portion 33b.
[0040]
The socket main body portion 171 is fixed to the floor surface by fitting the descending passage 33 to the descending passage fitting portion 171a at the upper end thereof, and is sealed from the drain pipe 90 by the sealing material 177 located at the upper end thereof. Even in the drain socket 170, the end of the downstream socket pipe 174 is positioned below the upper end of the drain pipe 90 to prevent leakage of washing water from the upper end of the drain pipe 90. As described above, the drain socket 170 is also made of the above resin such as vinyl chloride resin or ABS resin.
[0041]
The drain socket 170 causes the passing wash water that has passed through the upstream socket pipe line 172 to collide with the stepped portion 175 as shown by the arrow in the figure, and flows into the downstream socket pipe line 174 by changing its direction. Since the upper portion of the step portion 175 is expanded by the storage chamber 176, coupled with the change of the flow direction in the step portion 175, the wash water is temporarily stored and contributes to the induction of the siphon action. Therefore, in the flush toilet 10 equipped with the drain socket 170, the siphon action is induced at two locations of the end throttle portion 33b and the step portion 175 of the drain socket 170, so that it is possible to effectively improve the stored water suction force and the suction efficiency. Can be achieved. Since the siphon action can also be induced in the drain socket 170, the siphon action can be induced by attaching the drain socket 170 to the flush toilet 10 in which the end of the siphon trap, that is, the descending passage 33 end pipe is straight. it can.
[0042]
The washing water behavior at the drain socket 170 is as follows. The washing water (passing washing water) that has passed through the upstream socket pipe line 172 due to the siphon action induction flows into the downstream socket pipe line 174 as described above due to the collision with the stepped portion 175. On the other hand, a part of the passing wash water flows into the storage chamber 176 with a siphon-induced pressure, that is, a head pressure (head difference) with the surface of the stored water in the ball portion 20. At this time, air is present in the storage chamber 176, but this air is compressed by the above-mentioned pressure of the cleaning water, so that the cleaning water is stored in the storage chamber 176 correspondingly. That is, the storage chamber 176 functions as a kind of accumulator.
[0043]
At the end of the siphon, the amount of cleaning water that passes through the upstream socket conduit 172 and flows into the downstream socket conduit 174 decreases, and the pressure of the cleaning water that closes the storage chamber 176 at its lower end also decreases. In such a situation, the wash water stored in the storage chamber 176 flows out of the storage chamber 176 due to its own water pressure and its own weight, and increases the flow rate of the wash water that attempts to pass through the downstream socket pipe line 174. Therefore, the area occupied by the washing water in the pipe cross section of the downstream socket pipe 174 is wider than that in the case where the washing chamber 176 is not provided and the washing water direction is changed at the step portion 175. The air entering from the side can be suppressed by the washing water present in a wide occupation area. As a result, the drain socket 170 of the second embodiment can achieve the same effects as the above-described embodiment.
[0044]
Further, the drain socket 170 replenishes cleaning water from the surrounding storage chamber 176 to the periphery of the upstream socket conduit 172 at the end of the upstream socket conduit 172. For this reason, the flow rate increase through the replenishment of the washing water can be easily executed.
[0045]
In the drain socket 170 of the second embodiment, the storage chamber 176 that surrounds the upstream socket conduit 172 is used. However, the drain socket 170 may be modified to be formed on one side of the upstream socket conduit 172. FIG. 5 is an explanatory view for explaining a drain socket 170A of this modification. This drain socket 170A is provided with a protrusion 178 in the vicinity of the end of the upstream socket conduit 172, and a storage chamber 176 on the side facing this protrusion 178. In the drain socket 170A, as shown by an arrow in the drawing, the passing wash water that collides with the protrusion 178 and changes its direction enters the storage chamber 176. Therefore, also with the drain socket 170A of this modified example, the washing water can be replenished from the storage chamber 176 in the same manner as in the second embodiment.
[0046]
  nextReference examplesWill be described. FIG.Reference examplesIt is explanatory drawing for demonstrating the drain socket 270 of. As shown in the figure, a drain socket 270 of this modification has a socket body portion 271 for fixing the floor surface, and a socket conduit 272 for guiding the passing wash water to the drain pipe 90 therein. The drain socket 270 has a throttle mechanism capable of narrowing and adjusting the pipe diameter of the socket pipe 272. This throttling mechanism includes a pipe line restricting member 273 disposed opposite to the socket pipe line 272, an actuator 274 for moving the pipe member back and forth in the pipe line, and an actuator control device (not shown).
[0047]
The pipe line restricting member 273 is made of an elastic material having excellent water resistance and durability, such as rubber and elastomer, and is watertightly fixed to the pipe line wall 275 around the socket pipe line 272. In response to a command from the control device, the actuator 274 curves the pipe restricting member 273 into the pipe line and pushes it toward the pipe wall surface. The actuator control device determines the end of the siphon based on the elapsed time from the start of toilet flushing, the pressure change in the socket conduit 272, and the like, and drives and controls the actuator as follows according to the result.
[0048]
When toilet flushing is started by a handle operation or button operation (not shown), the actuator control device issues a forward command to the actuator 274 to drive it, and as shown in the drawing, the conduit restriction member 273 is moved into the conduit. put out. Thereby, since the pipe line of the socket pipe line 272 is narrowed, the passage of the washing water through the socket pipe line 272 is restricted during this period. Even under such a restriction, the siphon action is induced in the end throttling portion 33b of the descending path 33, and the washing water passes through the socket pipe line 272. Therefore, the suction of the accumulated water and the filth is performed without special support. Thus, even when the pipe line restricting member 273 is approaching, the pipe line between them is configured to have no support for filth transfer. In addition, as shown in the drawing, the state where the 273 is approaching can also be set as the origin position of the aperture mechanism. In this case, the actuator driving described above is not necessary.
[0049]
If the actuator control device determines that the siphon end is approaching due to the elapsed time or the like, the actuator control device issues a backward command to the actuator 274 to drive it, and draws the pipe line limiting member 273 toward the pipe wall surface. . As a result, the pipe line of the socket pipe line 272 is expanded from the previous state, so that the restriction on the passage of the wash water due to the narrowing of the pipe line is relaxed, and the amount of wash water passing through the socket pipe line 272 downstream of the throttle mechanism is increased. The Therefore, at the end of the siphon, since the occupied area of the passing washing water in the socket conduit 272 downstream of the throttling mechanism is increased, it is possible to maintain the siphon pipe as described above, and to improve the suction efficiency of the ball portion stored water, The same effects as those of the above embodiments can be obtained.
[0050]
As mentioned above, although the form in which the present invention is implemented was explained, the present invention is not limited to such an example at all, and it is needless to say that the present invention can be carried out in various modes without departing from the gist of the present invention. is there.
[0051]
For example, in the above embodiment, a low tank type tank connected to the toilet bowl is used as the wash water tank. However, a tank other than the low tank type tank, for example, a toilet bowl connected to the toilet bowl through a washing pipe and installed on a toilet wall, etc. A cornered tank or a flat tank may be used. In this case, it is possible to install a washing water tank at a high position to make a high tank.
[0052]
Moreover, although the case where the present invention is applied to the siphon jet flush toilet 10 and the siphon toilet bowl has been described as an example, it can be understood as an invention in which the toilet bowl is combined with other devices and members. For example, sanitary washing devices combined with functional toilet seats that realize various functions such as local washing and heating, toilet kit devices combined with storage cabinets and hand-washing devices, wall materials, floor materials and ceiling materials as toilet room structures The system toilet apparatus etc. which combined etc. can be considered.
