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, 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. (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 control unit 5 controls the cleaning device 3. The control of the cleaning device 3 by the control unit 5 will be described in detail later.

  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, after the above-described rim cleaning process before the standard mode is started, cleaning water is supplied to the toilet bowl 6 via the jet discharge port 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, after the above-described rim cleaning process before the standard mode is completed and after the standard mode jet cleaning process is started, cleaning 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 pre-foam jet cleaning step, it is preferable to discharge the cleaning water from the jet discharge port 10 to such an extent that the toilet drain passage 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 apparatus 1 in the foam mode will be described in more detail.

  After the user operates the cleaning switch (when the foam mode is selected by the foam mode switch), the control unit 5 controls the cleaning device 3 to supply the flush water to the toilet bowl 6 through the jet outlet 10. Perform a pre-jet cleaning step for foam. As a result of the pre-foam jet cleaning step being performed, the water level WL1 in the toilet bowl 6 is disturbed, so that the foam covering the water level WL1 and the toilet paper riding on the foam are in a wet state, and discharge 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 the pre-foam rim cleaning step of supplying cleaning water to the toilet bowl 6 via the rim discharge port 8. By executing 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 is completed, the foam attached to the wall surface of the toilet bowl 6 can be reliably removed. Further, in this case, even if the toilet drain passage 13 from the bottom of the toilet bowl 6 to the drain pipe (not shown) is broken, the odor does not 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.

  The above toilet apparatus 1 has a toilet bowl 6 having a rim discharge port 8 at the top and a jet discharge port 10 at the bottom, supplying flush water to the toilet bowl 6 via the rim discharge port 8, and A cleaning device 3 for supplying cleaning water to the toilet bowl 6 via the toilet bowl 10 and a toilet drainage channel 13 from the bottom of the toilet bowl 6 to a drainage pipe (not shown). A drain trap 7 for determining the height of a pool surface WL1 of cleaning water stored in the bottom of the bowl 6 and a control unit 5 for controlling the cleaning device 3 are provided.

According to the toilet bowl device 1 according to the present embodiment described above in detail, the following effects can be obtained.
That is, in the toilet apparatus 1 according to the present embodiment, the control unit 5 supplies the pre-foam jet for supplying the wash water to the toilet bowl 6 through the jet outlet 10 when the foam is present on the reservoir surface. After the cleaning step and the pre-foam jet cleaning step are started, after the pre-foam rim cleaning step of supplying cleaning water to the toilet bowl 6 via the rim discharge port 8 and the pre-foam jet cleaning step are completed. In addition, after the pre-foam rim cleaning process is started, the post-foam jet cleaning process of supplying cleaning water to the toilet bowl 6 through the jet discharge port 10 and the pre-foam rim cleaning process and after the foam After the post-jet cleaning process is started, a post-foam rim cleaning process for supplying cleaning water to the toilet bowl 6 via the rim discharge port 8 is performed.
Thus, even when the foam is supplied to the toilet bowl 6, the foam can be easily and surely discharged, and the dirt and toilet paper on the foam can be easily and reliably discharged.

  In addition, when foam is present on the surface of the pool, the control unit 5 executes the pre-foam jet cleaning step to open the toilet drain passage from the bottom of the toilet bowl 6 to the drain pipe. Thereby, the foam covering the pool surface WL1 can be more easily and reliably discharged from the toilet bowl 6.

  In addition, when bubbles are present on the surface of the pool water, the control unit 5 executes the pre-foam rim cleaning process before the foam pre-jet cleaning process is completed, so that The attached bubbles can be reliably dropped, and the bubbles covering the pool surface WL1 can be more easily and reliably discharged from the toilet bowl 6. Further, even if the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drain pipe is broken, the odor does not return from the drain pipe. That is, odor return can be prevented.

When the control unit 5 performs control in the standard mode in which cleaning is performed using cleaning water containing no foam, the rim cleaning process before the standard mode in which cleaning water is supplied to the toilet bowl 6 through the rim discharge port 8 is performed. A standard mode jet cleaning step of supplying cleaning water to the toilet bowl 6 via the jet outlet 10 after the start of the pre-mode rim cleaning step, and a standard mode jet cleaning step after the pre-standard mode rim cleaning step is completed. After the start of the rim cleaning step, a rim cleaning step after the standard mode in which the washing water is supplied to the toilet bowl 6 via the rim discharge port 8 is executed. To set a longer processing time.
As a result, the water level WL1 in the toilet bowl 6 reliably returns to the original height, so that the next post-foam jet cleaning step can be reliably performed.

  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.

  In the above embodiment, when bubbles are present on the surface of the pool, the pre-foam jet cleaning step, the pre-foam rim cleaning step, the post-foam jet cleaning step, and the post-foam rim cleaning step, Although the configuration is such that the steps are sequentially performed, for example, a rim cleaning step may be further performed before the foam pre-jet cleaning step. That is, the pre-foam rim cleaning process, the pre-foam jet cleaning process, the foam rim cleaning process, the post-foam jet cleaning process, and the post-foam rim cleaning process may be sequentially performed. In this case, the pre-foam rim cleaning may be continued during the pre-foam jet cleaning.
