Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In the following embodiments, the directions such as the up-down direction will be described with reference to the state where the toilet stool is installed.
Fig. 1 is a diagram schematically showing an example of a toilet bowl flushing system according to embodiment 1.
As shown in fig. 1, the toilet bowl washing system 1 of the present embodiment includes water supply lines 6 and 8 for supplying washing water to the toilet bowl 2. In the present embodiment, the toilet bowl washing system 1 is configured to supply wash water to a single toilet bowl 2. Further, an example is shown in which the toilet 2 to be supplied with washing water is a urinal used in an upright position.
The toilet 2 includes a bowl portion (bowl portion) 3, a water supply portion 4 connected to water supply paths 6 and 8, and a drain portion 5 for discharging urine and washing water.
The water supply unit 4 is provided with a discharge unit such as a sprayer for discharging the washing water along the inner surface of the toilet bowl unit 3.
The drain section 5 forms a bowl-shaped trap or a P-shaped trap and is connected to the drain passage 9. The toilet 2 may be a so-called floor-mounted type vertically long urinal which is placed on a floor, or a wall-mounted type urinal which is hung on a wall surface. The toilet 2 may be included and grasped as the toilet flushing system 1. In other words, the toilet apparatus may be grasped as a toilet apparatus including the toilet 2 and the toilet cleaning system 1.
The toilet bowl washing system 1 further includes a bypass water supply passage 10, and the bypass water supply passage 10 is branched from the water supply passages 6 and 8 and connected to a water discharge passage 9 connected to the water discharge portion 5 of the toilet bowl 2. Hereinafter, the water supply path 6 on the upstream side (water supply source side) of the branch portion 10a branching and connecting the bypass water supply path 10 will be described as the upstream water supply path 6, and the water supply path 8 on the downstream side (toilet bowl 2 side) of the branch portion 10a will be described as the downstream water supply path 8.
The bypass water supply path 10 is provided with a bypass valve 11, and the bypass valve 11 opens and closes the bypass water supply path 10 to supply and block the cleaning water. The bypass water supply path 10 is provided with a backflow preventing portion 12 such as a backflow preventing valve (check valve, one-way valve) for preventing backflow to the upstream side. The backflow prevention unit 12 is provided downstream of the bypass valve 11 (on the side of the drain passage 9). The downstream end of the bypass water supply passage 10 is connected to a portion of the horizontal tubular drain passage 9 relatively close to the drain portion 5. The downstream end of the bypass water supply passage 10 may be connected to the upstream end of the portion of the drain passage 9 extending in the substantially horizontal direction.
The toilet bowl washing system 1 further includes an air bubble mixing portion 13 for bubbling air and mixing the air into the wash water supplied to the bypass water supply path 10. In the present embodiment, the air bubble mixing portion 13 is provided in the upstream side water supply passage 6 on the upstream side of the branch portion 10a branching and connecting the bypass water supply passage 10, and mixes the air bubbles. The air bubble mixing portion 13 may be configured to mix fine air bubbles of one or both of a millimeter level and a micrometer level. The void ratio (the area ratio of the bubbles contained in each unit cross-sectional area of the fluid) of the bubble-containing washing water (fine bubble-containing washing water) into which the fine bubbles are mixed in the bubble mixing portion 13 may be set to about 5% to 40%, and preferably about 10% to 30%.
In the present embodiment, the air bubble mixing portion 13 includes a venturi-shaped air-liquid mixing portion 16 provided as a pressure rapid change portion in the upstream side water supply passage 6, and an air introduction portion 14 that introduces air into the air-liquid mixing portion 16. The air introduction portion 14 may be configured such that the tip of the pipe is open to the atmosphere, or may be configured such that an opening/closing valve is provided in the middle of the pipe. The air inlet 14 may be configured to introduce a gas containing a functional gas such as a carbonic acid gas or an ozone gas into the air. In the present embodiment, a flow rate adjusting unit 15 capable of adjusting the flow rate of the air supplied to the air-liquid mixing unit 16 is provided downstream of the air introducing unit 14. The adjustment of the porosity may be performed by adjusting the flow rate adjustment unit 15.
The gas-liquid mixing portion 16 is provided with a nozzle-shaped throttle portion, and air is introduced from the air introduction portion 14 by an ejector effect due to a negative pressure action of the washing water ejected through the throttle portion. The air introduced in this way is cut and fragmented by a sudden pressure change action when passing through the small-diameter portion and the large-diameter portion of the air-liquid mixing portion 16, and is mixed into the washing water as fine bubbles. According to such a configuration, if the cleaning water is made to flow through the upstream water supply passage 6, the bubble-containing cleaning water can be generated by taking in air by the negative pressure action, so that the replenishment of the chemical agent or the like is not required, and the influence on the environment due to the discharge of the chemical agent can be made less likely to occur.
The downstream water supply path 8 is provided with a water supply valve 7 for opening and closing the downstream water supply path 8 to supply and shut off the cleaning water. The water supply valve 7 is provided downstream of the gas-liquid mixing portion 16. The upstream water supply passage 6 may be in communication with a tap water pipe or the like as a water supply source. That is, the water supply system of the toilet bowl washing system 1 may be a direct water pipe pressure type. Instead of providing the water supply valve 7 and the bypass valve 11 separately, a three-way switching valve or the like functioning as the water supply valve 7 and the bypass valve 11 may be provided in the branch portion 10 a.
In the toilet bowl washing system 1 configured as described above, if the water supply valve 7 is opened with the bypass valve 11 closed, bubble-containing washing water in which fine bubbles are mixed is generated when passing through the gas-liquid mixing portion 16, and this bubble-containing washing water is supplied to the bowl portion 3 of the toilet bowl 2 via the downstream side water supply path 8. Such a cleaning operation may be performed by an operation of a cleaning operation unit provided in the toilet bowl 2, or by detection of approach and separation of a human body by a human body detection sensor.
Further, if the water supply valve 7 is closed and the bypass valve 11 is opened, the bubble-containing washing water generated when passing through the gas-liquid mixing portion 16 as described above is directly supplied to the drain passage 9 via the bypass water supply passage 10.
For example, after the above-described washing operation, a drain path washing mode in which bubble-containing washing water is supplied to the bypass water supply path 10 may be performed. That is, the following structure can be made: when the washing operation is performed, a toilet washing mode for supplying bubble-containing washing water to the bowl portion 3 of the toilet 2 is executed, and thereafter, a drain washing mode for supplying bubble-containing washing water to the drain 9 is executed.
Further, the following structure may be made: if the flushing operation is not executed until a predetermined time set in advance elapses, both or one of the toilet flushing mode and the drain flushing mode as described above is executed. That is, the following structure may be adopted: in the case where the cleaning mode is not used for a long period of time, the cleaning mode is executed.
Although not shown, such a cleaning operation is executed by controlling each part by a control unit provided at an appropriate position of the toilet cleaning system 1, the control unit including a control circuit such as a CPU, a storage unit, and the like.
In addition, the foam-containing washing water may be supplied to the bowl portion 3 of the toilet bowl 2 in the drainage path washing mode. That is, if the water supply valve 7 and the bypass valve 11 are opened, the bubble-containing washing water can be branched at the branch portion 10a and supplied to the bowl portion 3 and the drain passage 9 of the toilet 2 via the downstream side water supply passage 8 and the bypass water supply passage 10, respectively.
The toilet bowl cleaning system 1 of the present embodiment can effectively clean the drain path 9 connected to the drain portion 5 of the toilet bowl 2 by adopting the above-described configuration.
That is, the air bubble mixing portion 13 is provided to bubble air and mix the air into the wash water supplied to the bypass water supply path 10. Therefore, the bubble-containing washing water can be directly supplied to the drain passage 9 connected to the bypass water supply passage 10 without passing through the toilet bowl 2. That is, the bubble-containing washing water can be supplied to the drain passage 9 without passing through the bowl portion 3 and the drain portion 5. This can suppress the reduction of bubbles contained in the bubble-containing washing water reaching the drainage channel 9, as compared with a configuration in which the bubble-containing washing water is supplied to the drainage channel 9 via the bowl portion 3 and the drainage portion 5. As a result, contaminants such as urine scale (calcium ions and bacteria) adhering to the inner surface of the drainage path 9 can be effectively removed by adsorbing the contaminants to the bubbles contained in the bubble-containing washing water, and accumulation of the urine scale can be effectively suppressed.
In the present embodiment, the following configuration is adopted: an air bubble mixing portion 13 is provided in the upstream side water supply passage 6 on the upstream side of the branch portion 10a branching and connecting the bypass water supply passage 10 so as to mix air bubbles therein. Therefore, the bubble-containing washing water can be supplied to the toilet 2 as well, and the washing performance of the toilet 2 can be improved.
In the present embodiment, the bubble-containing washing water is branched at the branch portion 10a and can be supplied to both the toilet bowl 2 and the bypass water supply path 10 at the same time. Therefore, both the bowl portion 3 and the water discharge channel 9 of the toilet bowl 2 can be cleaned more effectively than if the foam-containing cleaning water is selectively supplied to the toilet bowl 2 or the bypass water supply channel 10.
Next, another embodiment of the present invention will be described with reference to the drawings.
In the following embodiment, differences from embodiment 1 will be mainly described, and the same components will be denoted by the same reference numerals, and the description thereof will be omitted or simplified.
Fig. 2 is a diagram schematically showing an example of the toilet bowl flushing system according to embodiment 2.
The toilet bowl washing system 1A of the present embodiment is configured to supply washing water to the plurality of toilet bowls 2, and 2 by branching the downstream side water supply path 8 into a plurality of (3 in the drawing). Branch pipes 8A, and 8A of the downstream-side water supply passage 8 are connected to the water supply portions 4, and 4 of the toilet bowls 2, and 2, respectively. The branch lines 8A, and 8A are provided with water supply valves 7, and 7, respectively, as described above.
Further, a backflow preventing portion 12 similar to the above is provided at a downstream side portion of the bypass water supply passage 10. A bypass valve 11 similar to the above is provided on the upstream side of the backflow prevention part 12 of the bypass water supply path 10.
In addition, in the present embodiment, the following configuration is made: an air bubble mixing portion 13A is provided in the upstream side water supply passage 19 on the upstream side of the branch portion 10a branching and connecting the bypass water supply passage 10 so as to mix air bubbles therein. In the present embodiment, the upstream end of the upstream water supply passage 19 is connected to the water storage part 18. That is, the water supply system of the toilet bowl washing system 1A is not a direct water supply system but a tank type (pump-pressurized type).
The water storage unit 18 is supplied with cleaning water from a water supply pipe 6A such as a tap water pipe. A suitable level gauge is provided in the water storage portion 18 to store washing water at a predetermined level.
In the present embodiment, the air bubble mixing portion 13A is configured as follows: the washing water in which air is dissolved under pressure is depressurized to obtain fine bubbles, thereby generating bubble-containing washing water in which the fine bubbles are mixed. According to such a configuration, it is possible to mix finer bubbles into the washing water than in a case where the fine bubbles are mixed into the washing water by the cutting, crushing, or the like due to the above-described sudden pressure change action.
The air bubble mixing portion 13A includes an air introduction pipe 14A for introducing air, and a pump 15A for sucking the air introduced from the air introduction pipe 14A and the cleaning water in the water storage portion 18. The air bubble mixing unit 13A includes a dissolving tank 17, and the dissolving tank 17 is connected to the discharge side of the pump 15A, and is provided with a gas-liquid mixing tank, a gas-liquid separation tank, and the like for dissolving air into the wash water by pressurization of the pump 15A. The air bubble mixing section 13A includes a venturi-shaped pressure release section 16A for releasing the pressure on the downstream side of the dissolving tank 17.
In the toilet bowl washing system 1A having the above-described configuration, if the pump 15A is started and the water supply valve 7 of the toilet bowl 2 subjected to the washing operation is opened in a state where the bypass valve 11 is closed, the bubble-containing washing water mixed with the fine bubbles is supplied to the bowl portion 3 of the toilet bowl 2 subjected to the washing operation.
Further, if the pump 15A is started and the bypass valve 11 is opened, bubble-containing washing water is directly supplied to the drain passage 9 via the bypass water supply passage 10, substantially in the same manner as in the above-described embodiment 1. In addition, if the pump 15A is started and the bypass valve 11 is opened in a state where all the water supply valves 7, and 7 are closed, bubble-containing washing water can be supplied only to the bypass water supply passage 10 side. Further, in a manner substantially similar to the above, it is also possible to supply bubble-containing washing water to both the bowl portion 3 and the bypass water supply passage 10 of at least one toilet bowl 2 at the same time.
The toilet bowl washing system 1A of the present embodiment having the above configuration also achieves substantially the same effects as those of the above embodiment 1. In addition, in the present embodiment, the drainage path 9 connected to the drainage portions 5, 5 of the plurality of toilet bowls 2, 2 can be efficiently cleaned.
Further, some of the different structures described in the above embodiments may be combined or applied. The configurations of the above-described parts of the toilet bowl washing systems 1 and 1A according to the above-described embodiments are merely examples, and various modifications may be made in addition to these.
In the above embodiments, the toilet 2 to be cleaned by the toilet cleaning system 1 or 1A is exemplified as a urinal, but may be a squat type or a sitting type toilet.
