An embodiment of the present invention will be described in detail below with reference to the drawings.

A toilet device 1 according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. Here, FIG. 1 is a plan view of the toilet device 1 according to this embodiment. FIG. 2 is a vertical cross-sectional view of the toilet device 1 according to this embodiment viewed in the direction of arrow AA in FIG.

The toilet device 1 includes a toilet body 2 , a cleaning device 3 and a controller 5 .

The toilet bowl main body 2 is composed of a toilet bowl 6 for receiving filth, an ascending channel 13A and a descending channel 13B from the bottom of the toilet bowl 6, and is connected to a drain pipe (not shown) through a connecting pipe 14. A drainage trap 7 provided in the toilet drainage channel 13 and a toilet seat (not shown) and a toilet lid (not shown) that open and close with respect to the toilet bowl 6 are provided. A rim discharge port 8 for discharging cleansing water is formed in the upper portion of the toilet bowl 6, and a rim flow channel 9 for generating a swirling flow of cleansing water is formed along the periphery thereof. A jet discharge port 10 for discharging cleansing water is formed in the bottom of the toilet bowl 6 . The drain trap 7 determines the height of the water surface WL1 of flush water pooled 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).

The cleaning device 3 is controlled by a control unit 5 described later and operates to clean the toilet bowl 6 when a cleaning switch (not shown) is operated by the user. 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 or jet spouting). The cleaning device 3 operating in the standard mode supplies cleansing water containing no foam, and the cleaning device 3 operating in the foam mode causes foam to exist on the water surface in the toilet bowl 6 .

Here, examples of the bubble mode are as follows.
First, there is a case where bubbles discharged into the toilet bowl 6 flow into the pooled water. Specifically, when water containing bubbles is discharged and the inside of the toilet bowl 6 is swirled to wash the inside of the toilet bowl 6, or when water containing bubbles is discharged and bubbles are accumulated in pooled water (this In some cases, it is not necessary to turn the inside of the toilet bowl 6). As the water containing bubbles, there are cases in which bubbles are mixed in the washing water, and in cases in which the bubbles are discharged through a route separate from the washing water.

Secondly, there is a case where bubbles are generated in stagnant water. For example, there is a case where a chemical or the like is directly supplied into the pooled water via the jet outlet 10 or the like to generate bubbles in the pooled water. Even in this case, it is possible to create a state in which bubbles are present in the toilet bowl 6 .

In the first case described above, the cleaning device 3 includes an ejector (not shown) that generates bubbles by supplying and mixing chemicals and air into cleaning water. In contrast, in the second case described above, the cleaning device 3 does not need to be equipped with an ejector. Any chemical can be used as long as it can generate foam. For example, a liquid containing perfume, an antibacterial agent, a sterilizing agent, an antifungal agent, or the like, ionized water, or the like is used.

The controller 5 controls the cleaning device 3 . The control of the cleaning device 3 by the controller 5 will be detailed later.

The toilet device 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 the wall surface of the toilet room in which the toilet device 1 is installed. The remote controller of this embodiment includes a private part washing switch for washing the private part, a washing switch (large washing switch, small washing switch) for washing the toilet bowl, a foam mode switch, and the like.

Here, examples of triggers for the bubble mode are as follows.
Triggers for the foam mode when water containing foam is discharged to wash the inside of the toilet bowl 6 include the user entering the room, the user pressing the foam mode switch, the toilet seat/toilet lid opening, the user sitting down, the user the user leaves the seat, the toilet seat/toilet lid closes, and the user leaves the room.

Triggers for the foam mode when water containing foam is discharged and the foam is accumulated in the pooled water include the user entering the room, the user pressing the foam mode switch, the toilet seat/toilet lid opening, the user sitting down, Such a thing is mentioned.

Furthermore, when foam is generated in pooled water, triggers for the foam mode include the user entering the room, the user pressing the foam mode switch, the toilet seat/toilet lid opening, and the user sitting down.

Next, the operation of the toilet device 1 by the controller 5 will be described in detail with reference to FIGS. 3 and 4. FIG. Here, FIG. 3 is a flowchart for explaining the operation flow in the standard mode of the toilet device 1 according to this embodiment. FIG. 4 is a flowchart for explaining the flow of operations when bubbles exist on the stagnant water surface of the toilet device 1 according to the present embodiment (specifically, after execution of the above-described operation in the bubble mode). .

As shown in FIG. 3, when performing control processing in the standard mode for cleaning with cleaning water that does not contain bubbles, the control unit 5 performs a pre-standard mode rim cleaning process, a standard mode jet cleaning process, and a post-standard mode rim cleaning process. and a washing step.

First, in step S100, a pre-standard-mode rim cleaning process is executed. Specifically, in this step, washing water is supplied to the toilet bowl 6 through the rim outlet 8 . After that, the process proceeds to step S110.

Then, in step S110, a standard mode jet cleaning process is performed. Specifically, in this step, flush water is supplied to the toilet bowl 6 via the jet outlet 10 after the rim cleaning process before the standard mode is started. After that, the process proceeds to step S110.

Next, in step S120, a post-standard mode rim cleaning process is performed. Specifically, in this step, flush water is supplied to the toilet bowl 6 through the rim discharge port 8 after the above-described pre-standard-mode rim cleaning process is completed and after the standard-mode jet cleaning process is started. With the above, the present processing ends.

In this standard mode, the processing times of the standard mode jet cleaning process and the post-standard mode rim cleaning process are normally set to be the same, and the processing time of the pre-standard mode rim cleaning process is set to half of them.

Further, as shown in FIG. 4, when bubbles are present on the stagnant water surface, the control unit 5 controls the pre-foam jet cleaning process, the pre-foam rim cleaning process, the post-foam jet cleaning process, and the foam cleaning process. and a post-use rim cleaning step. However, it is not essential to perform a post-foam rim cleaning step.

First, in step S200, a pre-foam jet cleaning step is performed. Specifically, in this step, flush water is supplied through the jet outlet 10 toward the toilet drainage channel 13 or the drainage trap 7 . In this foaming pre-jet washing process, it is preferable to discharge washing water from the jet discharge port 10 to such an extent that the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drain pipe is sealed. Specifically, the washing water can be supplied through the jet outlet 10 until the upper surface of the foam on the stagnant water surface is positioned below the water sealing line SWL shown in FIG. preferable. This facilitates the discharge of foam in the toilet bowl 6, dirt on the foam, toilet paper, and the like. After that, the process proceeds to step S210.

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

As a result, the foam sticking to the wall surface of the toilet bowl 6 can be dropped from above by performing rim water spouting during the jet water spouting, and the jet water spouting can discharge the foam to the toilet bowl drainage channel 13. The foam on the wall surface of the can be flowed efficiently. If only the jet water is sprayed first, bubbles adhere to the wall surface of the toilet bowl 6 and remain, and if the rim water is sprayed first, the stagnant water surface rises and the bubbles float, and then the jet water is sprayed. Even if it does, bubbles remain in the toilet bowl 6. On the other hand, in the present embodiment, jet water is first discharged to drain the foam into the toilet drainage channel 13, and then rim water is spouted while the pooled water is lowered, so that the foam on the wall surface of the toilet bowl 6 is reliably removed. It is designed to be able to flow to After that, the process proceeds to step S220.

Next, in step S220, a post-foam jet cleaning step is performed. Specifically, in this step, flush water is supplied to the toilet bowl 6 through the jet outlet 10 after the pre-foam jet cleaning process is completed and after the pre-foam rim cleaning process is started. As a result, the foam remaining in the toilet bowl 6 is reliably discharged. After that, the process proceeds to step S230.

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

In addition, the processing time of each step in the main operation processing of FIG. Preferably, the wash step is set to 2.2 seconds and the post-foam rim wash step to 4.0 seconds. Also, the processing time of the pre-foam rim cleaning process is set longer than that of the above-described standard mode pre-rim cleaning process, for example, twice as long. As a result, the inside of the toilet bowl 6 is sufficiently washed, and the toilet drainage channel 13, which has been sealed in the pre-foam jet washing step, is quickly covered with water to ensure water sealing.

Next, the operation of the toilet device 1 in the foam mode will be described in more detail.

After the user operates the washing switch (when the foam mode is selected by the foam mode switch), the control unit 5 controls the washing device 3 to supply washing water to the toilet bowl 6 through the jet outlet 10. perform a pre-jet cleaning step for foam that supplies As a result of the water pooling surface WL1 in the toilet bowl 6 being disturbed by performing the pre-foaming jet cleaning process, the foam covering the pooling water surface WL1 and the toilet paper on the foam get wet, promoting discharge. When the pre-foam jet cleaning process is performed so as to maintain the water seal of the toilet drain channel 13 from the bottom of the toilet bowl 6 to the drain pipe, no odor returns from the drain pipe. When the pre-foam jet cleaning process is performed so as to break the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drain pipe, the foam covering the stagnant water surface WL1 is surely discharged from the toilet bowl 6. - 特許庁

After the pre-foam jet washing process is started, the controller 5 controls the washing device 3 to perform the pre-foam rim washing process of supplying washing water to the toilet bowl 6 through the rim discharge port 8 . By executing the pre-foam rim washing process, the water pool surface WL1 in the toilet bowl 6 rises to its original height, so that the next post-foam jet washing process can be performed. When the pre-foam rim washing process is executed before the pre-foam jet washing process ends, the foam adhering to the wall surface of the toilet bowl 6 can be reliably removed. Also, in this case, even if the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drainage pipe (not shown) is broken, the odor does not return from the drainage pipe.

After the pre-foaming rim washing process is started, the control unit 5 controls the washing device 3 to perform the post-foaming jet washing process of supplying washing water to the toilet bowl 6 through 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-foaming jet washing step. Further, the stagnant water surface WL1 in the toilet bowl 6 is lowered by executing the post-foaming jet washing step.

After the post-foam jet washing process is started, the controller 5 controls the washing device 3 to perform the post-foam rim washing process of supplying washing water to the toilet bowl 6 through the rim discharge port 8 . By executing the post-foam rim washing step, the water surface WL1 in the toilet bowl 6 is covered with foam. In addition, when operating in the bubble mode, washing water is supplied so that the pooled water surface WL1 is lower than in the case of operating in the standard mode. As a result, the water surface WL1 is low during the next wash, which facilitates the discharge of foam and toilet paper.

The above-described toilet device 1 includes a toilet bowl 6 having a rim discharge port 8 at the top and a jet discharge port 10 at the bottom, and flushing water being supplied to the toilet bowl 6 through the rim discharge port 8 and a jet discharge port. A washing device 3 that supplies flushing water to the toilet bowl 6 via a toilet bowl 6, and a toilet drainage channel 13 from the bottom of the toilet bowl 6 to a drain pipe (not shown). A drainage trap 7 that determines the height of a water surface WL1 for collecting washing water accumulated in the bottom of the bowl 6, and a control unit 5 that controls the washing device 3 are provided.

After the washing process and the pre-foam jet washing process are started, the pre-foam rim washing process of supplying washing water to the toilet bowl 6 through the rim discharge port 8 and the pre-foam jet washing process are completed. and after the pre-foam rim washing process is started, a post-foam jet washing process of supplying washing water to the toilet bowl 6 through the jet outlet 10, and after the pre-foam rim washing process is finished and for foam. and a post-foaming rim washing step of supplying wash water to the toilet bowl 6 through the rim discharge port 8 after the post-jet washing step is started.
As a result, even when foam is supplied to the toilet bowl 6, the foam can be easily and reliably discharged, and the filth, toilet paper, etc. on the foam can be easily and reliably discharged.

In addition, when foam exists on the surface of the stagnant water, the control unit 5 executes the pre-foam jet cleaning step, thereby breaking the toilet drainage channel from the bottom of the toilet bowl 6 to the drainage pipe. Thus, the foam covering the stagnant water surface WL1 can be more easily and reliably discharged from the toilet bowl 6. - 特許庁

Further, when bubbles are present on the surface of the stagnant water, the controller 5 causes the pre-foam rim washing process to be executed before the pre-foam jet washing process ends, so that the wall surface of the toilet bowl 6 is Adhering foam can be reliably removed, and foam covering the stagnant water surface WL1 can be more easily and reliably discharged from the toilet bowl 6.例文帳に追加Further, even if the toilet drainage channel 13 from the bottom of the toilet bowl 6 to the drainage pipe is broken, the odor does not return from the drainage pipe. That is, odor return can be prevented.

Further, when performing control in the standard mode in which washing is performed with washing water that does not contain foam, the control unit 5 performs a pre-standard mode rim washing step of supplying washing water to the toilet bowl 6 through the rim discharge port 8, and a standard washing step. After the pre-mode rim washing process is started, a standard mode jet washing process of supplying wash water to the toilet bowl 6 through the jet outlet 10, and a standard mode jet washing process after the pre-standard mode rim washing process is completed. is started, a post-standard mode rim washing step of supplying washing water to the toilet bowl 6 through the rim outlet 8 is executed, and the pre-foam rim washing step is compared with the pre-standard mode rim washing step. to set a longer processing time.
As a result, the stagnant water surface WL1 in the toilet bowl 6 is reliably returned to the original height, so that the next post-foaming jet washing process can be reliably performed.

Although preferred embodiments of the toilet device 1 of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified as appropriate.

In the above embodiment, when bubbles are present on the stagnant water surface, the pre-foam jet cleaning process, the pre-foam rim cleaning process, the post-foam jet cleaning process, and the post-foam rim cleaning process are performed. Although it is configured to be executed sequentially, for example, the rim cleaning process may be further executed before the pre-foam jet cleaning process. That is, the pre-foam rim cleaning process, the pre-foam jet cleaning process, the intermediate foam rim cleaning process, the post-foam jet cleaning process, and the post-foam rim cleaning process may be sequentially executed. In this case, the pre-foam rim wash may continue to flow during the pre-foam jet wash.
