Description

  The present invention relates to an apparatus for supplying a chemical solution such as a cleaning agent to a toilet using water at the time of flushing a flush toilet.

  In a so-called tankless toilet without a low tank or a flush toilet equipped with a low tank without hand-washing, a chemical supply tool is provided on the rim of the toilet bowl as a device for supplying chemicals such as cleaning agents into the toilet bowl. There is one in which a chemical solution is supplied by using water at the time of flushing (Patent Document 1).

  However, since the main body of such a chemical liquid supply device is installed in the bowl of the toilet bowl, the chemical liquid supply device is easily contaminated with stool or the like, and the visual feeling is uncomfortable. For this reason, this type of chemical supply device is rarely used in Japan even though it is widespread overseas without a hand-washed low tank. That is, in Japan, a flush toilet with a hand-washed low tank uses a chemical supply tool that uses hand-wash water (Patent Document 2), and a flush toilet without a hand-washed low tank uses a spray-type cleaning agent. Has been.

  However, in a flush toilet without a hand-washed low tank, spraying the cleaning agent every time it is used is cumbersome and it may be difficult to secure a place for the cleaning agent.

  On the other hand, the present invention provides a chemical solution discharge device that can discharge a chemical solution into a bowl of a toilet bowl and can be installed so as not to become dirty with a stool, etc., even in a flush toilet without a low tank with a hand wash. The purpose is to do.

  When the present inventor uses the pressing force when sitting on the toilet seat when the toilet is used, it becomes unnecessary to install the main body of the chemical discharging device in the toilet bowl bowl, and the chemical is discharged. It has been found that only the nozzles to be arranged need to be arranged, and thereby the above-mentioned object can be achieved.

That is, the present invention relates to a nozzle part that discharges a chemical solution into a toilet bowl of a flush toilet equipped with a toilet seat, a chemical solution storage part that is arranged outside the bowl of the toilet bowl, and a toilet unit that is disposed between the toilet bowl and the toilet seat. A chemical solution discharge device including a chemical solution supply mechanism that supplies the chemical solution stored in the chemical solution storage portion to the nozzle portion by the pressing force from the nozzle is provided.

  According to the chemical solution discharge device of the present invention, the chemical solution storage unit and the chemical solution supply mechanism for supplying the chemical solution from the chemical solution storage unit to the nozzle unit are disposed outside the bowl of the toilet bowl, so that the chemical solution discharge device is prevented from being contaminated with stool or the like. it can.

  Moreover, the nozzle part which discharges a chemical | medical solution can also be arrange | positioned in the position which cannot be seen under the toilet seat. Therefore, the user of the toilet can use the toilet without a sense of incongruity.

  Furthermore, in the chemical supply tool that uses low tank hand-washing water, the chemical liquid supplied from the chemical liquid supply tool is diluted with a large amount of water, so the concentration of the chemical remaining in the water seal in the bowl after flushing is extremely high. However, according to the present invention, by increasing the viscosity of the chemical solution, the adhesion to the inner wall surface of the bowl can be improved and the cleaning effect can be improved. That is, the chemical solution adhering to the inner wall surface of the bowl is exposed only to a short amount of flowing water during flushing, and the amount of flowing water in the horizontal wall portion of the inner wall of the bowl is relatively small. A considerable amount remains, and the chemical concentration of water remaining in the water seal portion can be increased.

  Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1 is a perspective view of a chemical liquid discharging apparatus 1A according to an embodiment of the present invention, FIG. 2A is a perspective view of a state in which it is attached to a toilet of a flush toilet, and FIG. FIG.

  This chemical solution discharge apparatus 1A includes a container 2 serving as a chemical solution storage unit, a manual pump device 3 including a cylinder and a piston attached to a mouth portion thereof, a liquid guide tube 4 and a liquid guide tube 4 communicating with the manual pump device 3. The nozzle part 5 which makes | forms the front-end | tip part is provided.

  As the container 2, a plastic molded body having an arbitrary shape can be used.

  As the manual pump device 3, a hand pump that is generally used as a discharge device for household cleaning agents and the like can be used. More specifically, the liquid guide pipe 4 connected to the piston is disposed on the container 2 side. By manually pushing in, a predetermined amount of the chemical solution stored in the container 2 is discharged, and by releasing the push, the liquid guide tube 4 is restored to the position before the push by the spring material built in the pump. Can be used.

  A plate-like member 7 that extends in a U-shape is attached to the cap 6 that covers the mouth of the container 2 as a fixture for attaching the container 2 to the toilet 20 so as to sandwich the rim portion 21 of the toilet 20. The plate-like member 7 can be attached to the cap 6 by a slide lock mechanism 8 as shown by an arrow in FIG. As will be described later, the slide lock mechanism 8 functions as a position adjusting member that adjusts the distance from the rim portion 21 of the liquid guide tube 4 disposed between the rim portion 21 of the toilet 20 and the toilet seat 22.

  The liquid guide tube 4 is bent so as to be laid over the rim portion 21 of the toilet bowl 20 in a U-shape when the chemical liquid discharge device 1A is attached to the toilet bowl 20, and is placed on the rim portion 21 of the liquid guide tube 4.
