Description

  The present invention relates to a male flush toilet used exclusively for men's small water.

  In men's flush toilets, in order to keep the toilet surface clean, the user's push button operation after urination, automatic operation by human body detection means such as optical sensors, automatic operation at regular intervals by timer setting, etc. The washing water is made to flow down from the washing nozzle provided on the top of the nozzle. In addition, as a men's flush toilet in recent years, the consumption of washing water has been reduced to enable significant water savings, and drug components added to washing water for the purposes of sterilization, deodorization, antifouling, etc. are effective. In order to reduce the waste of being left and discarded, a circulation type that automatically collects the used cleaning water and repeatedly reuses it is becoming widespread. In this circulation type flush toilet for men, the presence of the user is detected by the human body detection means, and the user's small water is guided to the drain pipe, while the drainage flow path is circulated by the switching valve after the user leaves. The washing water that has flowed down the toilet surface flows into the circulating washing water tank and is collected, and the collected washing water is supplied to the washing nozzle via the circulation pump and the discharge pump (for example, Patent Document 1). And the toilet surface of the conventional flush toilet for men including this circulation type is generally vertical from the upper part on the front side to the height close to the drain.

Japanese Patent No. 3853825

  However, in the conventional men's flush toilet, when the outflow pressure of the wash water from the wash nozzle increases, a large amount of splashes are generated at the lower part of the toilet surface that is gently inclined toward the drain outlet, and scattered to the surroundings. There is a limit to the outflow pressure of the washing water, and there is a problem that the cleaning power cannot be sufficiently increased, and the front side of the toilet bowl is vertical, so depending on the angle of urination, small water bounced off the toilet bowl vertical plane. There was also a problem that the splashes were easily scattered outside the toilet bowl.

  In view of the above-described circumstances, the present invention is a men's flush toilet, and even if the outflow pressure of the washing water is increased, it is difficult for splashes to scatter to the surroundings, and thus sufficient washing power can be exerted with high outflow pressure. At the same time, it is intended to provide a device that can effectively prevent the splash of small water from splashing outside the toilet.

  If the means for achieving the above object is shown with reference numerals in the drawings, the flush toilet for men according to the invention of claim 1 is such that the front side of the toilet surface 2 is inward from the upper end to the lower side. The forward inclined portion 21 located at the top of the toilet surface 2 is moved from the lower end of the forward inclined portion 21 to the descending inclined portion 23 to the drainage port 3 through the concave curved portion 22, A cleaning nozzle 4 that discharges cleaning water W obliquely downward along the inclination of the forward inclined portion 21 is provided.

  According to the invention of claim 2, in the flush toilet for men of claim 1, the forward tilt angle of the forward inclined portion 21 of the toilet surface 2 with respect to the vertical surface of the upper side 21a is larger than the forward inclined angle of the lower side 21b. The configuration is set.

  According to a third aspect of the present invention, in the flush toilet for men according to the first or second aspect, the upper end of the forward inclined portion 21 of the toilet bowl surface 2 is continuous with the lower end of the top front wall 1a of the toilet body 1.

  The invention of claim 4 is the male flush toilet of claim 1 or 2, comprising a washing water circulation mechanism S that collects the washing water W flowing down the toilet surface 2 and reuses it for toilet flushing. Yes.

  Next, effects of the present invention will be described with reference numerals in the drawings. First, in the men's flush toilet according to the first aspect of the invention, the wash water W discharged from the wash nozzle 4 flows down along the forward inclined portion 21 on the front side of the toilet surface 2, and the concave curved portion 22 and It flows into the drain port 3 at the lower end through the descending slope part 23. Thus, the forward inclined portion 21 of the toilet surface 2 is located on the inner back side as the lower portion, and the inflow surface smoothly descends through the concave curved portion 22 from the innermost lower end of the forward inclined portion 21. 23. Therefore, even if the outflow pressure of the washing water W from the washing nozzle 4 is increased, splashing is unlikely to occur in the lower part of the toilet surface 2, and the generation position is at the innermost depth of the toilet surface 2. Even if a small amount of droplets is generated, it does not scatter to the outside of the toilet, so that a sufficient washing power can be exerted with a high outflow pressure. Moreover, since the front side of the toilet bowl surface 2 is the forward inclined portion 21 during urination, the reflection direction of the small water U hitting the forward inclined portion 21 is lower than the reflection direction with respect to the vertical plane. Since there is a psychological effect that the user can easily turn the direction of urination to the lower back side due to the shape of the toilet surface 2, the splash of the small water U is less likely to be scattered outside the toilet. On the other hand, since the front side of the toilet surface 2 forms the forward inclined portion 21, the internal space 10 at the top of the toilet body 1 becomes large. Therefore, various devices such as a pump and a tank are used by using the internal space 10. Class and accessories can be placed.

  According to the invention of claim 2, since the forward inclination angle of the upper side 21 a in the forward inclined portion 21 of the toilet surface 2 is larger than that of the lower side 21 b, even if urination is high toward the upper side 21 a, The rebound is reliably directed downward, preventing splashes from splashing out of the toilet bowl, and the wash water W discharged along the upper side 21a from the washing nozzle 4 strongly hits the lower side 21b at an angle. Therefore, the lower side 21b, which is easily contaminated with small water, is efficiently cleaned.

  According to the invention of claim 3, the upper end of the forward inclined portion 21 of the toilet surface 2 is continuous with the lower end of the top front wall 1 a of the toilet body 1, so that the internal space 10 in the upper part of the toilet body 1 is larger. Accordingly, the degree of freedom in arrangement and configuration of devices and accessories in the internal space 10 is increased, and the size restriction is reduced.

  According to the invention of claim 4, as a circulatory male flush toilet, a wide internal space in the upper part of the toilet body 1 is used for the devices constituting the wash water circulation mechanism S, for example, the circulation pump P 1, the sub tank T 2, the control device C and the like. 10 and can be easily maintained in the upper position.

It is a vertical side view of the men's flush toilet concerning one embodiment of the present invention. It is a front view of the flush toilet for men. The washing nozzle of the flush toilet for men is shown, (a) is a longitudinal front view, and (b) is a longitudinal side view. It is a schematic diagram which illustrates the flow-path structure of the washing water circulation mechanism of the flush toilet for men.

  Below, the circulation type men's flush toilet provided with the washing water circulation mechanism as one embodiment of the present invention is explained concretely with reference to drawings. The present invention is not limited to the configuration of the embodiment.

  As shown in FIGS. 1 and 2, this men's flush toilet has a drainage port 3 fitted with a pan 6 on the bottom of a concave toilet surface 2 constructed on the front side of the toilet body 1, and the upper part thereof. A cleaning nozzle 4 is provided, and a human body detecting means 5 including an optical sensor or the like for detecting the presence of a user is provided on the top front wall 1 a of the toilet body 1. A drain pipe 8 with a trap 8a connected to the sewer is connected directly below the drain port 3 via a switching valve unit 7 constituting a washing water circulation mechanism described later.

  As shown in FIG. 1, the front side of the toilet surface 2 constitutes a forward inclined portion 21 located on the inner back side from the upper end to the lower portion, and passes through the concave curved portion 22 from the lower end of the forward inclined portion 21. It has shifted to a gently descending slope part 23 to the drain port 3, whereby the bottom part is recessed and widened in the front-rear direction. The forward tilting portion 21 is set such that the forward tilt angle with respect to the vertical surface of the upper side 21a that is slightly concavely curved is larger than the forward tilt angle of the lower side 21b. In addition, the upper end of the forward inclined portion 21 is continuous with the lower end of the top front wall 1a of the toilet main body 1, and the wide internal space 10 is formed above the toilet main body 1 in combination with the inclined form of the forward inclined portion 21. Has been.

  As shown in FIG. 3, the cleaning nozzle 4 has a plurality (six in the figure) of discharge holes 41 formed along the lower edge of the horizontally long oval case 40 in a front view, and flows from the introduction port 42. The washing water W is configured to be discharged obliquely downward along the forward inclined portion 21 of the toilet surface 2 with a lateral expansion. The case 40 is fitted into the mounting hole 11 of the toilet front wall 1b constituting the toilet surface 2 from the rear, and is fixed to the toilet front wall 1b by a mounting screw 44 at the rear end flange portion 43.

  In the flush toilet for men having the above-described configuration, the wash water W discharged from the wash nozzle 4 flows down along the forward inclined portion 21 on the front side of the toilet surface 2, and the concave curved portion 22 and the descending slope portion 23. It flows into the drainage port 3 of a lower end through. At this time, the forward inclined portion 21 of the toilet surface 2 is located on the inner back side as the lower portion, and the inflow surface smoothly descends through the concave curved portion 22 from the innermost lower end of the forward inclined portion 21. 23, even if the outflow pressure of the washing water W from the washing nozzle 4 is increased, splashing is unlikely to occur in the lower part of the toilet surface 2, and the position where the splash occurs is the innermost of the toilet surface 2. Because it is in the back, even if a small amount of splash occurs, it does not scatter outside the toilet. Therefore, in this men's flush toilet, the washing water W can be discharged at a high outflow pressure, and sufficient washing power can be exhibited.

  On the other hand, when urinating, since the front side of the toilet surface 2 is the forward inclined portion 21, as shown in FIG. 1, the reflection direction of the small water U hitting the forward inclined portion 21 is reflected to the vertical surface. Since the bottom side of the toilet surface 2 is recessed in addition to the downward direction from the direction, there is also a psychological effect that the user can easily turn the direction of urination to the lower back side. Splashes are less likely to splash outside the toilet bowl, and the amount of dirt around the toilet bowl is reduced accordingly, facilitating cleaning.

  In particular, as in the embodiment, if the forward inclination angle of the upper side 21a in the forward inclined portion 21 of the toilet surface 2 is larger than that of the lower side 21b, urination is increased toward the upper side 21a as indicated by the reference symbol Ua in FIG. Even if it is done, the splash of the small water U is surely directed downward, so that splashing of splashes outside the toilet is prevented. Further, the cleaning water W discharged along the upper side 21a having a larger forward tilt angle than the cleaning nozzle 4 strikes the lower side 21b having a smaller forward tilt angle strongly with an angle. The lower side 21b that is easily contaminated can be efficiently and reliably washed. The forward tilt angle of the forward tilt portion 21 is not particularly limited, but is preferably about 20 to 40 ° with respect to the vertical surface on the upper side 21a and about 5 to 15 ° on the lower side 21b.

  Furthermore, in such a flush toilet for men, the front side of the toilet surface 2 forms a forward inclined portion 21, and thus the internal space 10 above the toilet body 1 becomes large. Various devices such as tanks and accessories can be arranged. In particular, as in the embodiment, in the structure in which the upper end of the forward inclined portion 21 of the toilet surface 2 is continuous with the lower end of the top front wall 1a of the toilet body 1, the internal space 10 on the upper portion of the toilet body 1 becomes larger, and accordingly The degree of freedom in arrangement and configuration of devices and accessories in the internal space 10 is increased, and size restrictions are reduced. In particular, in the case of a circulatory male flush toilet, it is necessary to arrange a large amount of equipment constituting the flush water circulation mechanism S in the toilet body. However, as shown in FIGS. 10, the circulation pump P1, the discharge pump P2, the sub tank T2, the chemical liquid tank T3, the control device C, and the like can be accommodated, whereby the maintenance work can be easily performed at the upper position.

  An example of the washing water circulation mechanism of this men's flush toilet is shown in FIG. In this cleaning water circulation mechanism S, the switching flow path unit 7 directly below the drain outlet 3 can switch the drain flow path between the drain pipe 8 side and the recovery flow path L1 side to the cleaning water storage tank T1. The wash water W in the wash water storage tank T1 is sent to the upper sub tank T2 through the circulation flow path L2 by the circulation pump P1, and further sent from the sub tank T2 to the washing nozzle 4 through the circulation flow path L3 by the discharge pump P2. And is discharged from the washing nozzle 4 to the toilet surface 2. Note that the inside of the virtual line frame in the figure shows the internal space 10 above the toilet body 1, and the circulation pump P 1, the discharge pump P 2, the sub tank T 2, and the chemical liquid tank T 3 are accommodated in the internal space 10.

  The sub-tank T2 is connected to a drain channel L4 that hangs down from the bottom via the on-off valve V1 and an overflow channel L5 that overflows excess cleaning water W. The cleaning water W is discharged into the cleaning water storage tank T1. In addition, a drain flow path L6 that is connected to the drain pipe 12 from the bottom thereof via the on-off valve V2 is connected to the wash water storage tank T1. Further, on the cleaning water storage tank T1, an outlet of a water supply path L7 for supplying new cleaning water W from a water pipe (not shown) through an opening / closing valve V3, and an opening / closing valve V4 for supplying a chemical D from the chemical liquid tank T3. And an outlet of a chemical liquid supply path L8 to be supplied via the line. A float switch F is provided in the wash water storage tank T1, and when the stored wash water W is reduced to an amount that requires replenishment, the float switch F detects it from the liquid level, The on-off valves V3 and V4 of the water supply path L7 and the chemical liquid supply path L8 are opened for a predetermined time.

  For example, when the washing water circulation mechanism S is set to the two-stage washing method, the drainage flow path from the drainage port 3 is connected to the drainage pipe 8 side in the standby state, and the user stands in front of the toilet surface 2. When this is detected by the human body detection means 5, a small amount (for example, about 150 ml) of the washing water W is discharged from the washing nozzle 4 as the initial washing at that time or immediately after the user leaves after urination, and the pre-washing washing is performed. Water W and small water U are discharged to the drain pipe 8. Next, after a certain time (for example, 8 seconds) after the user leaves, the switching valve unit 7 switches the drainage channel to the recovery channel L1 side, and a relatively large amount (for example, about 1000 ml) from the cleaning nozzle 4 as main cleaning. The cleaning water W of the main cleaning is led to the cleaning water storage tank T1 through the recovery flow path L1 and recovered.

  As the wash water circulation mechanism S, various mechanisms other than those exemplified in FIG. 4 can be adopted. For example, the sub tank T2 is omitted, and a check valve is interposed in the flow path instead of directly from the wash water storage tank T1. Alternatively, the cleaning water W may be supplied to the cleaning nozzle 4. Moreover, the flush toilet for men of this invention includes the thing which does not have this washing water circulation mechanism S. In addition, in the present invention, the structure of the toilet body 1, the shape of the toilet surface 2, the structure of the drainage port 3, the shape and mounting structure of the washing nozzle 4, the position of the human body detection means 5, and the internal space 10 of the toilet body 1 are accommodated. Various design changes other than the embodiment can be made for the detailed configuration such as the type and shape of the equipment, the arrangement configuration, the piping configuration, the switching mechanism of the switching valve unit 7, and the like.
