Description

  The present invention relates to a toilet equipped with a detergent tank.

  Conventionally, Patent Document 1 discloses that a toilet bowl is washed by foaming a foam-generating liquid and supplying it to a bowl of the toilet bowl.

  In this conventional example, a foam generating liquid is stored in a tank of a warm water washing toilet seat device attached to a toilet, and bubbles are generated using this foam generating liquid and supplied to the bowl.

  The warm water washing toilet seat device is attached to the upper part of the toilet, and the entire tank for storing the foam-generating liquid is disposed between the left wall of the toilet room and the left side of the toilet.

  As described above, in the case where the tank is positioned on the left side of the toilet bowl as viewed from the front, when the foam generating liquid is replenished, it is necessary to supply the foam generating liquid to the tank positioned on the left side of the toilet bowl as viewed from the front.

  However, since the inside of the toilet room is narrow, the space between the left and right walls in the toilet room and the left and right side portions of the toilet is narrow, and as described above, the left wall in the toilet room and the left side portion of the toilet bowl In order to replenish the foam-generating liquid in the tank located between the toilet and the left side wall of the toilet room and the left side of the toilet, the person puts in a half-body posture and puts the container containing the foam-generating liquid It must be held in one hand to replenish the foaming liquid from the container into the tank.

  Here, when a person who is half-finished tries to perform the above-mentioned work in a half-body posture such that his / her face is directed to the left wall of the toilet room, the face is pressed against the wall, and therefore the work of replenishing the foam generating liquid is performed. Extremely difficult. In addition, the tank is placed between the left wall of the toilet room and the left side of the toilet, but because it is biased toward the toilet, it faces the left wall of the toilet room as described above. In order to perform the above replenishment work in a half body posture, the container containing the foam-generating liquid must be held in the right hand and the replenishment work must be performed toward the back side of the right hand. There is a problem to say.

  It is also conceivable to perform the above replenishment work by putting the body on its left side facing the left wall and between the left wall and the left side of the toilet bowl. Because it is located on the opposite side of the wall, it can be positioned above the toilet and there is no feeling of pressure, but if you hold the container with foam generating liquid in your right hand and try to replenish the tank, twist the upper body There is a problem that it is difficult to work. In order not to twist the upper body, it is conceivable to hold the container with the left hand and replenish the tank, but there are many right-handed people, so there is a problem that it is difficult to work with the left hand.

In the conventional example, a translucent window is provided in the center of the front of the tank in the vertical direction so that the remaining amount of foam generating liquid in the tank can be seen. Since the bubble generation liquid is replenished to the upper side beyond the translucent window provided in the vertical center of the front surface of the tank, it is not known whether or not an adequate amount has been replenished even if this translucent window is seen. There is a fear of overflowing.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The toilet bowl 1 of the present invention is configured such that cleaning water containing detergent flows through the bowl portion 9.

  As shown in FIG. 3, the toilet 1 includes a bowl portion 9, an outer shell 10, a trap portion 11, a washing water discharge device 12, a detergent supply means 13, and a toilet accessory such as a hot water washing device. It is.

  The trap part 11 is disposed at the rear part of the bowl part 9, and in the embodiment, the trap part 11 is arranged in the trap case 11 a and has one end connected to the drain part of the rear end part of the bowl part 9. This is a turn trap type constituted by a simple trap cylinder 11b, and the trap cylinder 11b is rotated by a motor (not shown) to form a trap structure in which the trap cylinder 11b has an upward U shape. The trap shape is released and the state of draining can be selected. Moreover, the lower end part of the trap case 11a serves as a drain outlet, and is connected to a discharge cylinder (not shown) provided on the floor where the toilet 1 is installed.

  As shown in FIG. 3, normally, the trap cylinder 11b has an upward U-shaped trap structure, and the cleaning water is stored in the lower part of the bowl 9 and in the trap cylinder. When the urine or urine is finished, flush water is poured into the bowl portion 9 and the trap tube is rotated to release the trap structure state so that the flush water is drained together with filth. It has become.

  The cleaning water discharger 12 is for supplying cleaning water to the bowl portion 9, and in the embodiment of FIG. 3, an example of a tankless system is shown. That is, the cleaning water passage 15 is provided from the water supply to the bowl portion 9, and the cleaning water opening / closing valve 16 provided in the cleaning water passage 15 is opened so that the cleaning water is supplied to the bowl portion 9 from the downstream end of the cleaning water passage 15. The discharge of cleaning water is stopped by closing.

  Of course, a system in which the stored water in the low tank is allowed to flow through an on-off valve may be used. In the case of the tankless system, the cleaning water may be supplied by a pressure feed pump.

  The cleaning water discharge port 34 at the downstream end of the cleaning water flow path 15 is discharged from the one side end of the rear part of the bowl part 9 toward the front along the upper part of the inner surface of the bowl part 9. It flows as a swirl flow inside.

  The washing water spouting device 12 is provided with fine bubble generating means 17 for mixing air into the washing water, miniaturizing the air to generate fine bubbles, and including the fine bubbles in the washing water. The washing water containing fine bubbles has a water-saving effect due to a decrease in bulk specific gravity, and has a silencing effect and a water splash prevention effect due to friction reduction when the washing water collides with the inner surface of the bowl portion 9, as well as a swirling flow. Thus, there is a bubble cleaning effect capable of powerfully peeling and adsorbing dirt adhering to the inner wall of the bowl portion 9 due to shock waves generated when the fine bubbles collide with the inner wall of the bowl portion 9 and bursting, and adsorption characteristics of the bubble interface.

  As shown in FIG. 4, the fine bubble generating means 17 is configured by a tube portion 20 in which an air mixing portion 18 is provided in the washing water flow path 15 and a venturi-shaped pressure sudden change portion 19 is provided downstream thereof. The air mixing part 18 is configured by connecting an air supply pipe 23 having a check valve 22 around the downstream side of the nozzle part 21 whose diameter of the washing water flow path 15 is reduced. The air is sucked and mixed into the cleaning water by the negative pressure generated by ejecting the water.

  The sudden pressure change portion 19 has a structure in which a reduced diameter portion 24 for reducing the diameter, a throat portion 25 for the reduced diameter, and an enlarged diameter portion 26 for increasing the diameter are connected in order from the upstream side. When the washing water flows through the sudden pressure change portion 19, the air mixed in 18 is first expanded due to a decrease in internal pressure at the reduced diameter portion 24 and the throat portion 25, and subsequently a shear force due to an increase in internal pressure at the expanded diameter portion 26. And shattered and refined by the action of shock waves. As the fine bubble generating means 17, a type in which mixed air is dissolved in the cleaning water and then precipitated can be used.

  As shown in FIGS. 3 and 4, the detergent supply means 13 includes a detergent tank 2, a detergent supply path 28 that connects the detergent tank 2 and the detergent mixing section 27 provided in the washing water flow path 15, and a detergent supply path 28. And a detergent opening / closing valve 30.

  The detergent supply path 28 has a circulation path part 31 in which the start end part 40 a of the forward path part 40 and the terminal end part 41 a of the return path part 41 are located in the detergent tank 2, and is branched from the middle of the circulation path part 31. And a supply path portion 32 that reaches the detergent mixing portion 27. The detergent pump 29 is provided in the circulation path section 31, and the detergent opening / closing valve 30 is provided on the downstream side of the supply path section 32.

  When the detergent pump 29 is driven, the liquid detergent stored in the detergent tank 2 circulates in the circulation path 31, so that the detergent is prevented from clogging due to solidification or the like in the detergent supply path 28. ing.

  The detergent mixing unit 27 is a part that generates a negative pressure in the washing water that flows by reducing the diameter of the washing water channel 15. In the embodiment shown in the accompanying drawings, the throat part 25 is the detergent mixing unit 27. .

  The detergent opening / closing valve 30 is opened when a negative pressure of the washing water is applied in the detergent mixing section 27 and the detergent pump 29 is driven to apply the pump pressure, and a certain detergent is put in the washing water. It is supposed to be mixed.

  The cleaning water containing bubbles mixed with the detergent is discharged into the bowl portion 9 from the cleaning water discharge port 34 at the downstream end of the cleaning water flow path 15 and turns into a swirling flow and travels to the inner surface of the bowl portion 9 all the way. The detergent that has been mixed in exhibits a detergent cleaning effect on the inner surface of the bowl portion 9 to enable effective cleaning. In addition, the surface tension of water is reduced by mixing detergent (surfactant), and the diameter of the fine bubbles generated by the fine bubble generating means 17 can be reduced from the order of mm to μm. The fine bubbles of the order of μm have properties that are much harder to break than the fine bubbles of the order of mm, and the fine bubbles remain for a long time when the wash water remains in the bowl portion 9 after the bowl portion 9 is washed. Thus, the effect of preventing the adhesion of dirt in the vicinity of the waterline of the stored water can be achieved.

  Next, installation of the detergent tank 2 will be described.

  In the present invention, the detergent tank 2 is attached to the upper portion of the right side surface portion 1a in front view of the outer shell 10 of the toilet bowl 1.
