Description

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

  BACKGROUND ART Conventionally, a toilet apparatus for supplying foam to a toilet bowl has been known. The main purpose of the supply of foam to the toilet bowl is to suppress the scattering of liquid during male standing urination and to wash the toilet bowl. However, the foam supplied to the toilet bowl does not disappear immediately, and may cause clogging due to resistance in the drain pipe depending on the method of supplying the washing water. Therefore, a toilet apparatus has been proposed in which acidic water is discharged from a rim spout to foam in a toilet bowl, and foam attached to the inner surface of the toilet bowl is defoamed before drainage (for example, see Patent Document 1). .

JP 2009-079426 A

  By the way, although toilet paper is difficult to flow when it is placed on foam, in the toilet apparatus of Patent Document 1, although there is a description about eliminating foam, toilet paper placed on such foam is described. No consideration has been given to the emission of CO2.

  The present invention has been made in view of the above problems, and an object of the present invention is to make it possible to easily flush toilet paper on foam that covers a reservoir surface even when foam is supplied to a toilet bowl. It is to provide a device.

  (1) In order to achieve the above object, the present invention provides a toilet bowl (for example, a toilet bowl 6 to be described later) and a cleaning device that supplies cleaning water containing foam to the toilet bowl to wash the toilet bowl ( For example, a cleaning device 3 described below), an ejection device (e.g., an ejection device 4 described later) that ejects a liquid toward a pool surface (for example, a pool surface WL1 described later) in the toilet bowl, A control unit (for example, a control unit 5 to be described later) that controls the ejection device, wherein the control unit starts the ejection of the liquid by the ejection device before or at the start of the washing by the washing device. A toilet device (for example, a toilet device 1 described later) to be provided is provided.

  (2) In the toilet device of (1), it is preferable that the control unit continues the ejection of the liquid by the ejection device for a predetermined time during the washing by the washing device.

  ADVANTAGE OF THE INVENTION According to this invention, even if it supplies foam to a toilet bowl, the toilet bowl apparatus which can easily flush the toilet paper on the foam which covers a reservoir surface can be provided.

It is a top view of the toilet bowl device concerning one embodiment of the present invention. It is the longitudinal cross-sectional view of the toilet bowl apparatus which concerns on one Embodiment of this invention seen in the arrow AA direction of FIG. It is a flowchart explaining the flow of operation | movement in the standard mode of the toilet bowl apparatus which concerns on one Embodiment of this invention. It is a flowchart explaining the flow of operation | movement in case foam exists on the reservoir surface of the toilet bowl apparatus which concerns on one Embodiment of this invention.

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

  The toilet device 1 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 vertical cross-sectional view of the toilet apparatus 1 according to the present embodiment as viewed in the direction of arrows AA in FIG.

  The toilet device 1 includes a toilet body 2, a cleaning device 3, an ejection device 4, and a control unit 5.

  The toilet body 2 is composed of a toilet bowl 6 for receiving filth, a bottom channel of the toilet bowl 6, an ascending channel 13A and a descending channel 13B, and is connected to a drain pipe (not shown) via a connecting pipe 14. The toilet includes a drain trap 7 provided in the toilet drain channel 13, a toilet seat (not shown) and a toilet lid (not shown) that open and close with respect to the toilet bowl 6. A rim discharge port 8 for discharging cleaning water is formed at an upper portion of the toilet bowl 6, and a rim flow passage 9 for generating a swirling flow of the cleaning water is formed along a peripheral edge thereof. At the bottom of the toilet bowl 6, a jet discharge port 10 for discharging cleaning water is formed. The drain trap 7 determines the height of the pool surface WL <b> 1 of the washing water that accumulates at the bottom of the toilet bowl 6 by sealing the toilet drain channel 13 from the bottom of the toilet bowl 6 to a drain pipe (not shown).

  When the user operates a cleaning switch (not shown), the cleaning device 3 operates under the control of the control unit 5 described below, and cleans the toilet bowl 6. Specifically, the cleaning device 3 functions as a rim cleaning water supply device that supplies cleaning water to the toilet bowl 6 through the rim discharge port 8, and supplies cleaning water to the toilet bowl 6 through the jet discharge port 10. It functions as a jet cleaning water supply device. (Hereinafter also referred to as rim spouting and jet spouting). The cleaning device 3 operating in the standard mode supplies cleaning water containing no bubbles, and the cleaning device 3 operating in the foam mode causes bubbles to be present on the pool surface in the toilet bowl 6.

Here, examples of the bubble mode include the following, for example.
First, there is a case where the foam spouted into the toilet bowl 6 flows into the pool water. Specifically, when the water containing the foam is spouted and the inside of the toilet bowl 6 is washed while turning the toilet bowl 6 or the like, or when the water containing the foam is spouted and the foam is accumulated in the stored water (this In such a case, it is not always necessary to rotate the toilet bowl 6). In addition, as water containing bubbles, there are a case where bubbles are mixed into the cleaning water and a case where bubbles are discharged through a different route from the cleaning water.

  Second, there is a case where bubbles are generated in the pool water. For example, there is a case where a drug or the like is directly supplied into the reservoir water via the jet discharge port 10 or the like to generate bubbles in the reservoir water. Even in this case, a state in which bubbles are present in the toilet bowl 6 can be formed.

  In the above-described first case, the cleaning device 3 includes an ejector (not shown) that generates a foam by supplying and mixing the medicine and the air into the cleaning water. On the other hand, in the second case described above, the cleaning device 3 does not need to include an ejector. The agent may be any agent that can generate foam, and for example, a liquid containing a fragrance, an antibacterial agent, a disinfectant, a fungicide, ionized water, or the like is used.

  The ejection device 4 includes an ejection nozzle (not shown) that ejects the liquid toward the pool surface WL1 in the toilet bowl 6. As the liquid, for example, water to be supplied is used, and various liquids may be used. The injection nozzle sprays (sprays) the liquid in a mist state, for example. Preferably, the spray device 4 sprays water widely toward the inner wall surface of the toilet bowl 6 in the form of a mist in order to suppress contamination by dirt in the toilet bowl 6. That is, the toilet apparatus 1 of the present embodiment restricts the spraying (spraying) of water by the spraying device 4 on the pool surface WL1 and uses it for discharging toilet paper on the foam covering the pool surface WL1. It is.

  More specifically, the ejection device 4 is configured to eject the liquid from above the stored water to wet the entire stored water surface WL1. Therefore, the entire toilet paper placed on the foam gets wet, so that the toilet paper is easily discharged. In this regard, as a pre-cleaning before use, a technique is known in which a liquid such as water is sprayed and wetted toward the wall surface of the toilet bowl and flows down to the pool water along the wall surface. By directly injecting the liquid onto the entire water surface WL1, the toilet paper can be wetted and discharged. Hereinafter, the injection device 4 will be described in this preferred embodiment.

  The injection device 4 is controlled and operated by a control unit 5 described below when a user operates a cleaning switch described below. Specifically, before starting the cleaning of the toilet bowl 6 in the foam mode by the cleaning device 3, the spraying of the atomized water (mist) toward the pool water surface WL1 in the toilet bowl 6 is started. Alternatively, when the cleaning device 3 starts cleaning the toilet bowl 6 in the foam mode by the cleaning device 3, the spray device 4 starts spraying the atomized water (mist) toward the reservoir surface WL1 in the toilet bowl 6.

  Further, it is preferable that the spraying device 4 continuously sprays water for a predetermined time during the cleaning by the cleaning device 3. Thereby, discharge of the toilet paper on the foam covering the pool surface WL1 is further promoted. The duration may be set in advance, and may be continued until the cleaning by the cleaning device 3 is completed.

  The control unit 5 controls the cleaning device 3 and the injection device 4. Specifically, before or at the start of the cleaning of the toilet bowl 6 in the foam mode by the cleaning device 3, the control unit 5 sprays the water atomized by the spray device 4 toward the pool surface WL1 in the toilet bowl 6. Start spraying.

  Note that the toilet apparatus 1 includes a remote controller (not shown) as an operation unit for executing various controls by the control unit 5. 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 part, a cleaning switch (large cleaning switch, small cleaning switch) for cleaning a toilet, a bubble mode switch, and the like.

Here, as the trigger of the bubble mode, for example, the following are exemplified.
As a trigger of the foam mode when the water containing foam is spouted to wash the inside of the toilet bowl 6, the user enters the room, the user presses the foam mode switch, the toilet seat / lid opens, the user sits, , The toilet seat / closure lid closes, and the user leaves the room.

  In addition, as a trigger of the foam mode in the case where water containing foam is discharged to accumulate foam in the stored water, the user enters the room, the user presses the foam mode switch, the toilet seat / toilet lid opens, the user sits down, And so on.

  Furthermore, triggers of the bubble mode when generating bubbles in the pool water include a user entering a room, a user pressing a bubble mode switch, opening a toilet seat / lid, and a user sitting.

  Next, the operation of the toilet device 1 by the control unit 5 will be described in detail with reference to FIGS. 3 and 4. Here, FIG. 3 is a flowchart illustrating the flow of operation in the standard mode of the toilet apparatus 1 according to the present embodiment. FIG. 4 is a flowchart for explaining the flow of the operation when bubbles are present on the pool surface of the toilet device 1 according to the present embodiment (specifically, after the operation in the above-described foam mode is performed). .

  As shown in FIG. 3, when performing the control process in the standard mode in which the cleaning is performed with the cleaning water containing no foam, the control unit 5 performs the rim cleaning process before the standard mode, the standard mode jet cleaning process, and the rim after the standard mode. And a cleaning step.

  First, in step S100, a rim cleaning step before the standard mode is executed. Specifically, in this step, washing water is supplied to the toilet bowl 6 via the rim discharge port 8. Thereafter, the process proceeds to step S110.

  Next, in step S110, a standard mode jet cleaning step is performed. Specifically, in this step, washing water is supplied to the toilet bowl 6 via the jet outlet 10. Thereafter, the process proceeds to step S110.

  Next, in step S120, a post-standard mode rim cleaning step is performed. Specifically, in this step, washing water is supplied to the toilet bowl 6 via the rim discharge port 8. As described above, this processing ends.

  In the standard mode, the processing time of the standard mode jet cleaning step and the processing time of the standard mode rim cleaning step are usually set to be the same, and the processing time of the standard mode pre-rim cleaning step is set to half of those times.

  Further, as shown in FIG. 4, when bubbles exist on the surface of the pool, the control unit 5 performs a pre-foam jet cleaning step, a pre-foam rim cleaning step, a post-foam jet cleaning step, And a rim cleaning step after use. However, it is not essential to perform the post-foam rim cleaning step.

  First, in step S200, a pre-foam jet cleaning step is performed. Specifically, in this step, the washing water is supplied to the toilet drainage channel 13 or the drainage trap 7 via the jet outlet 10. In this step, it is preferable that the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drain pipe is opened. Specifically, it is possible to supply the cleaning water through the jet outlet 10 until the upper surface of the foam on the reservoir surface is arranged below the water sealing line SWL shown in FIG. preferable. Thereby, discharge of foam in the toilet bowl 6, dirt on the foam, toilet paper, and the like is promoted. Thereafter, the process proceeds to step S210.

  Next, in step S210, a pre-foam rim cleaning step is performed. Specifically, in this step, after the above-described pre-foam jet cleaning step is started, cleaning water is supplied to the toilet bowl 6 through the rim discharge port 8. In this step, the processing time is longer than in the rim cleaning step before the standard mode. This pre-foam rim cleaning step is preferably performed before the pre-foam jet cleaning step ends.

  By discharging water from the rim during jet spouting, the foam attached to the wall surface of the toilet bowl 6 can be discharged from above to the toilet drainage channel 13 by jet spouting while dropping foam attached to the wall surface of the toilet bowl 6 from above. The bubbles on the wall can be flowed efficiently. If only the jet water discharge is performed first, bubbles adhere to the wall surface of the toilet bowl 6 and remain. Also, if the rim water discharge flows first, the reservoir surface rises and the bubbles float, and then the jet water discharge flows. Even if it does, the foam remains in the toilet bowl 6. On the other hand, in the present embodiment, first, the foam is discharged to the toilet drainage channel 13 by jet water spouting, and the rim water spouting is performed with the accumulated water lowered, so that the foam on the wall surface of the toilet bowl 6 can be reliably removed. It can be flushed. Thereafter, the process proceeds to step S220.

  Next, in step S220, a post-foam jet cleaning step is performed. Specifically, in this step, after the pre-foam jet cleaning step is completed and after the pre-foam rim cleaning step is started, cleaning water is supplied to the toilet bowl 6 via the jet discharge port 10. This ensures that the foam remaining in the toilet bowl 6 is discharged. Thereafter, the process proceeds to step S230.

  Next, in step S230, a post-foam rim cleaning step is performed. Specifically, in this step, the washing water is supplied to the toilet bowl 6 via the rim discharge port 8 after the pre-foam rim cleaning process is completed and the post-foam jet cleaning process is started. As described above, this processing ends.

  The processing time of each step in the main operation processing of FIG. 4 is, for example, 1.5 to 2.0 seconds for the pre-foam jet cleaning step, 4.0 seconds for the pre-foam rim cleaning step, Preferably, the cleaning step is set to 2.2 seconds, and the post-foam rim cleaning step is set to 4.0 seconds. Further, the processing time of the pre-rim cleaning step for foam is set to be longer, for example, twice as long as the above-described rim cleaning step before standard mode. As a result, the inside of the toilet bowl 6 is sufficiently washed, and the toilet drainage channel 13 that has been opened in the pre-foaming jet washing step is quickly covered with water, so that water sealing is ensured.

  Next, the operation of the toilet device 1 in the foam mode when the toilet paper is used after defecation will be described.

  When the washing switch is operated by the user, the control unit 5 controls the spraying device 4 to start spraying the atomized water (mist) toward the pool surface WL1 in the toilet bowl 6. The sprayed mist falls on the toilet paper on the foam covering the water surface WL1 in the toilet bowl 6, so that the toilet paper is in a wet state.

  Next, the control unit 5 controls the cleaning device 3 to supply cleaning water containing bubbles to the toilet bowl 6 from the rim discharge port 8 and the jet discharge port 10, thereby causing the toilet bowl 6 to be cleaned. At this time, since the toilet paper is in a wet state and is easily discharged, the toilet paper is reliably discharged together with dirt and the like. When the washing of the toilet bowl 6 is completed, the pool surface WL1 in the toilet bowl 6 is covered with the foam.

  Specifically, the control unit 5 controls the cleaning device 3 to execute a pre-foam jet cleaning step of supplying cleaning water to the toilet bowl 6 through the jet outlet 10. Thereby, as a result of the disturbance of the pool surface WL1 in the toilet bowl 6, discharge of foam and toilet paper is promoted. When the pre-foam jet cleaning step is performed so as to maintain the water seal of the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drainage pipe, no odor returns from the drainage pipe. When the pre-foam jet cleaning step is performed so as to seal the toilet drain passage 13 from the bottom of the toilet bowl 6 to the drain pipe, the foam covering the reservoir surface WL1 is reliably discharged from the toilet bowl 6.

  After the pre-foam jet cleaning step is started, the control unit 5 controls the cleaning device 3 to execute a pre-foam rim cleaning step of supplying cleaning water to the toilet bowl 6 via the rim discharge port 8. . By performing the pre-foam rim cleaning step, the pool surface WL1 in the toilet bowl 6 rises to its original height, so that the next post-foam jet cleaning step can be performed. When the pre-foam rim cleaning step is performed before the pre-foam jet cleaning step, the foam covering the pool surface WL1 is reliably discharged from the toilet bowl 6. Also, in this case, even if the toilet drain passage 13 from the bottom of the toilet bowl 6 to the drain pipe is broken, the rim washing water does not cause odor to return from the drain pipe.

  After the pre-foam rim cleaning step is started, the control unit 5 controls the cleaning device 3 to execute the post-foam jet cleaning step of supplying cleaning water to the toilet bowl 6 via the jet outlet 10. The excrement and toilet paper in the toilet bowl 6 are reliably discharged from the toilet bowl 6 by executing the post-foam jet cleaning process. In addition, the stored water level WL1 in the toilet bowl 6 is lowered by performing the post-foam jet cleaning process.

  After the start of the post-foam jet cleaning process, the control unit 5 controls the cleaning device 3 to execute the post-foam rim cleaning process of supplying cleaning water to the toilet bowl 6 via the rim discharge port 8. By executing the post-foam rim cleaning step, the water surface WL1 in the toilet bowl 6 is covered with the foam. Note that when operating in the bubble mode, the cleaning water is supplied such that the pool surface WL1 is lower than when operating in the standard mode. Thereby, at the time of the next washing, the discharge of the foam and the toilet paper is promoted due to the low water level WL1.

According to the toilet bowl device 1 according to the present embodiment described above in detail, the following effects can be obtained.
That is, the toilet bowl device 1 according to the present embodiment includes a toilet bowl 6, a cleaning device 3 that supplies cleaning water containing foam to the toilet bowl 6 to wash the toilet bowl 6, and a pool surface in the toilet bowl 6.

And
Thereby, even when the foam is supplied to the toilet bowl 6, the toilet paper on the foam covering the reservoir surface WL1 in the toilet bowl 6 can be adapted to the water, and thus the toilet paper can be easily flushed. Becomes possible.

  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.
