Description

  The present invention relates to a foam generator for supplying foam to a toilet bowl and a toilet device.

  BACKGROUND ART Conventionally, a toilet apparatus that supplies foam to a toilet bowl by providing an ejector has been proposed (for example, see Patent Literature 1). The ejector has a structure in which the diameter of the flow path of the cleaning water is reduced, and air and a medicine are supplied. In the toilet device provided with such an ejector, the flush water flows into the ejector, so that a venturi effect in which the inside of the ejector becomes a negative pressure occurs, and the air is drawn into the ejector. As a result, the washing water, the air, and the medicine are mixed to generate bubbles, and the washing water containing bubbles is supplied to the toilet bowl.

  By the way, the supply of foam to the toilet bowl is, for example, the main purpose of suppressing the splashing of liquid at the time of male standing urine and washing the toilet bowl. Very small. Therefore, even if a chemical such as a detergent containing a disinfectant or a fungicide is used, the disinfecting effect and the fungicide effect cannot be expected.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a foam generating device and a toilet device that can supply foam to a toilet bowl and that can be expected to have an effect of disinfecting and preventing mold in the toilet bowl. To provide.

  (1) In order to achieve the above object, the present invention provides a water supply device (for example, a water supply device 8 described later) for supplying cleaning water, and a flow path (for example, described later) through which the cleaning water supplied from the water supply device flows. A first flow path 9), an air supply path for supplying air to the flow path (for example, an air supply path 10 to be described later), and an on-off valve for opening and closing the air supply path (for example, an on-off valve 11 to be described later). A drug supply device (for example, a drug supply device 12 described later) for supplying a drug to the flow path, and a control unit (for example, described later) that controls the on-off valve and controls the amount of drug supplied by the drug supply device. (For example, a bubble generator 3 described later) provided with a control unit 13).

  (2) In the foam generation device according to (1), the control unit opens the on-off valve and relatively reduces the supply amount of the medicine and a first operation mode (for example, a foam mode described later); It is preferable to have a second operation mode (for example, a disinfection mode described later) in which the valve is closed and the supply amount of the medicine is relatively increased.

  (3) Further, the present invention provides a toilet device (for example, a toilet bowl 4 described later) including the foam generator of (1) or (2) and a toilet bowl (for example, a toilet bowl 4 described later) connected to the flow path. A toilet apparatus 1) is provided.

  According to the foam generator and the toilet device of the present invention, it is possible to supply foam to the toilet bowl by supplying water, air, and detergent to the flow path, and to supply water and detergent without supplying air to the flow path. By supplying it, the effect of disinfecting bacteria and preventing fungi in the toilet bowl can be expected.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

The toilet device 1 and the foam generator 3 according to the present embodiment will be described with reference to FIGS. 1 and 2.
Here, FIG. 1 is a plan view of the toilet apparatus 1 according to the present embodiment. FIG. 2 is a schematic diagram of the foam generator 3 according to the present embodiment. In FIG. 1, functional units are omitted for convenience.

  The toilet apparatus 1 includes a toilet body 2 and a foam generator 3. In addition, when the front-back direction when viewed from the user sitting on the toilet seat (not shown) of the toilet apparatus 1 is the front-back direction, the functional units such as the foam generator 3 are arranged on the rear side of the toilet body 2. You.

  The toilet body 2 includes a toilet bowl 4 for receiving waste, a drain pipe (not shown) extending downward from the bottom of the toilet bowl 4, a toilet seat (not shown) for opening and closing the toilet bowl 4, and a toilet lid (not shown). ). Discharge ports 5 and 6 for discharging cleaning water are formed in the upper part of the toilet bowl 4, and a rim flow path 7 that generates a swirling flow of cleaning water is formed along the periphery thereof.

  As shown in FIG. 2, the foam generator 3 includes a water supply device 8, a first flow path 9, an air supply path 10, an on-off valve 11, a medicine supply device 12, and a control unit 13. I have.

  The water supply device 8 supplies cleaning water to the first flow path 9 and a second flow path (not shown) described below, for example, when a cleaning switch (not shown) described later is operated by a user.

  The first flow path 9 is connected to the toilet bowl 4, and guides the wash water supplied from the water supply device 8 to the toilet bowl 4. Specifically, the first flow path 9 includes an upstream pipe 14, an ejector 15, and a downstream pipe 16.

  The upstream pipe 14 is provided upstream of the ejector 15, and guides the wash water supplied from the water supply device 8 to the ejector 15.

  The ejector 15 mixes the washing water supplied from the water supply device 8 with the medicine supplied from the medicine supply device 12 and the air supplied from the air supply passage 10, and then guides the mixture to the downstream pipe 16. Specifically, the ejector 15 includes, in order from the upstream side, a reduced diameter portion 15a, a reduced diameter portion 15b, and an enlarged diameter portion 15c.

  The reduced diameter portion 15a has a tapered shape whose diameter gradually decreases from the upstream side to the downstream side. The air supply path 10 is connected to the upper surface of the reduced diameter portion 15a. The small diameter portion 15b is smaller in diameter than the upstream reduced diameter portion 15a and the downstream enlarged diameter portion 15c. The medicine supply path 20 in the medicine supply device 12 is connected to the lower surface of the small diameter portion 15b. The enlarged diameter portion 15c has a tapered shape whose diameter gradually increases from the upstream side to the downstream side.

  The downstream pipe 16 is provided downstream of the ejector 15, and guides the wash water supplied from the ejector 15 to the toilet bowl 4.

  The second flow path (not shown) is connected to the toilet bowl 4, and guides the wash water supplied from the water supply device 8 to the toilet bowl 4 through a path different from the first flow path 9.

  The air supply path 10 supplies air to the ejector 15. Specifically, the air in the air supply passage 10 is drawn into the ejector 15 when the cleaning water is supplied to the ejector 15 and the inside of the ejector 15 becomes negative pressure while the on-off valve 11 is open. . The on-off valve 11 is provided in the middle of the air supply path 10 and opens and closes the air supply path 10.

  The medicine supply device 12 supplies a medicine to the ejector 15. Specifically, the medicine supply device 12 includes a medicine tank 17, a medicine pump 18, and medicine supply paths 19 and 20.

  The medicine tank 17 stores a medicine. The medicine tank 17 is connected to a medicine pump 18 via a medicine supply path 19. The medicine pump 18 is connected to the medicine tank 17 via a medicine supply path 19 and to the ejector 15 via a medicine supply path 20. The drug pump 18 pumps the drug stored in the drug tank 17 to the ejector 15.

  Here, in the present specification, the drug means a liquid containing components other than water, such as a fragrance, an antibacterial agent, a disinfectant, and a fungicide, in addition to a detergent. In addition, a liquid obtained by adding some functional change to water, such as ionic water generated by electrolysis of water or the like, is also included in the concept of the drug in this specification.

  The control unit 13 controls the supply of the wash water by the water supply device 8. The control unit 13 controls the on-off valve 11 and controls the amount of medicine supplied by the medicine supply device 12.

  Specifically, the control unit 13 has a bubble mode (first operation mode) and a bubble OFF mode (second operation mode), and can control switching of these operation modes. When operating in the bubble mode (first operation mode), the control unit 13 executes control to open the on-off valve 11 and relatively reduce the supply amount of the medicine. When operating in the bubble OFF mode (second operation mode), the control unit 13 executes control to close the on-off valve 11 and relatively increase the supply amount of the medicine.

  The toilet apparatus 1 includes a remote controller (not shown) as an operation unit for executing various controls by the control unit 13. The remote controller is attached to a wall surface of a toilet room where the toilet apparatus 1 is installed. The remote controller according to the present embodiment includes a local cleaning switch for cleaning a local area, a cleaning switch (large cleaning switch, small cleaning switch) for cleaning a toilet, and a purifying switch described later.

  Next, each operation mode of the foam generator 3 by the control unit 13 will be described in detail below. As described above, the bubble generator 3 operates in the bubble mode or the bubble OFF mode.

  The foam mode is an operation mode for supplying foam to the toilet bowl 4. The foam generator 3 operating in the foam mode generates bubbles with a very small amount of chemicals, and supplies cleaning water containing bubbles to the toilet bowl 4. On the other hand, the foam OFF mode is an operation mode in which the toilet bowl 4 exhibits a purifying effect such as a sterilization effect and a fungicidal effect. The foam generator 3 operating in the foam OFF mode supplies the flush water containing a large amount of medicine to the toilet bowl 4 without foaming.

The operation procedure in the bubble mode will be described.
In the bubble mode, for example, when the cleaning switch is operated by the user, the control unit 13 controls the water supply device 8 to supply the first channel 9 and the second channel with the cleaning water. At this time, the control unit 13 controls the medicine supply device 12 to supply the medicine stored in the medicine tank 17 to the ejector 15. Further, when the air supply path 10 is closed by the on-off valve 11, the control unit 13 controls the on-off valve 11 to open the air supply path 10.

  Then, the cleaning water supplied to the first flow path 9 flows into the ejector 15, and a venturi effect in which the inside of the ejector 15 becomes a negative pressure occurs. Due to the Venturi effect, air is drawn into the ejector 15 from the air supply path 10, and the washing water, the air, and the medicine are mixed in the ejector 15 to generate bubbles. The cleaning water containing bubbles is supplied to the toilet bowl 4 together with the cleaning water guided to the second flow path.

The operation procedure in the bubble OFF mode will be described.
In the bubble OFF mode, for example, when the purifying switch is operated by the user, the control unit 13 controls the water supply device 8 and supplies the first channel 9 and the second channel with the cleaning water. At this time, the control unit 13 controls the medicine supply device 12 to supply the medicine stored in the medicine tank 17 to the ejector 15. Further, when the air supply path 10 is opened by the on-off valve 11, the control unit 13 controls the on-off valve 11 to close the air supply path 10.

  Then, the cleaning water supplied to the first flow path 9 flows into the ejector 15, and a venturi effect in which the inside of the ejector 15 becomes a negative pressure occurs. By the Venturi effect, the washing water and the chemical are mixed in the ejector 15. At this time, since the air supply passage 10 is closed, no air is supplied into the ejector 15. The washing water containing only the chemical is supplied to the toilet bowl 4 together with the washing water guided through the second flow path.

  Note that, when the bubble generating device 3 operates in the bubble OFF mode, control for extending the operation time of the drug supply device 12 and increasing the supply amount of the drug is performed as compared with the case of operating in the bubble mode. . Specifically, the supply amount of the medicine is increased by extending the driving time of the medicine pump 18 or increasing the rotation speed of the medicine pump 18. Alternatively, by providing a flow control valve (not shown) in the medicine supply path 20 or the like and increasing the operation time and opening degree of the flow control valve while keeping the rotation speed and the drive time of the medicine pump 18 constant, the supply of the medicine is performed. Increase the amount.

  In addition, when the foam generator 3 operates in the foam OFF mode, control for extending the operation time of the water supply device 8 and increasing the supply amount of the cleaning water is also performed compared to the case where the foam generator 3 operates in the foam mode. Is done. Specifically, for example, the supply amount of the cleaning water is increased by increasing the operation time and the opening degree of a flow control valve (not shown) provided in the water supply device 8.

  Thereby, a large amount of medicine can be supplied to the toilet bowl without generating bubbles, and it becomes possible to exert a purifying action of a bactericidal agent, a fungicide and the like contained in the medicine.

According to the foam generating device 3 and the toilet device 1 according to the present embodiment described in detail above, the following effects are exerted.
That is, the foam generation device 3 and the toilet apparatus 1 according to the present embodiment include a water supply device 8 that supplies cleaning water, a first flow path 9 through which the cleaning water supplied from the water supply device 8 flows, and a first flow path. 9, an air supply path 10 for supplying air to the air supply 9, an on-off valve 11 for opening and closing the air supply path 10, a medicine supply device 12 for supplying a medicine to the first flow path 9, A control unit 13 for controlling the supply amount of the medicine by the device 12. This makes it possible to supply foam to the toilet bowl 4 by supplying water, air, and a medicine to the first flow path 9, and to supply a large amount of medicine without supplying air to the flow path by the on-off valve 11. It is possible to remove bacteria from the toilet bowl 4 and to prevent mold.

  As described above, the preferred embodiment of the toilet apparatus 1 of the present invention has been described, but the present invention is not limited to the above-described embodiment, and can be appropriately changed.
