Description

  The present invention relates to an improvement of a Western-style toilet device in which a foam layer is formed above stored water stored in a bowl portion of a toilet body.

  For example, as shown in Patent Document 1, a conventional flush-type western-style toilet device improves the cleaning effect in the bowl portion, prevents urination and water splashing during so-called defecation (so-called “hanging”), and creates bubbles in the cleaning liquid. A mixture is proposed.

  In such a toilet device, since the foam is formed on the entire surface of the water by mixing medicine, detergent, bubbles or the like into the cleaning liquid, the foam layer comes into contact with the inner peripheral surface of the bowl portion. The inner wall surface is protected, and it is possible to prevent the stool from adhering to the stool and the occurrence of dirt such as water scale near the boundary of the reservoir surface.

  In addition, even if the foam layer becomes thinner and disappears with time, cleaning liquid components such as mixed drugs will adhere to the part where the foam layer is in contact, so even if the foam disappears, The antifouling effect can be maintained by coating the components.

  However, if the water level of the accumulated water is constant, the portion below the accumulated water level on the inner surface of the bowl portion cannot be protected by foam unless the entire accumulated water is foamed.

Patent Document 2 discloses a Western-style toilet device that prevents rebound from the surface of the stored water by lowering the level of the stored water when the boy is small.
Japanese Patent Laid-Open No. 2002-88880 JP 2004-293147 A

  The present invention has been proposed in view of the above circumstances, and its object is to provide a Western-style toilet that coats a wider area of the inner surface of the bowl with foam by moving the water level of the water in the bowl. To provide an apparatus.

In order to achieve the above-mentioned object, the Western-style toilet device according to claim 1 is a western-style toilet device in which a foam layer is formed above the pooled water in the bowl portion of the toilet body. During this time , with a foam layer formed above the stored water, a part of the stored water is discharged, and the surface of the stored water is moved to a lower position in the bowl, and a film is formed on the moving surface. It is characterized by having a water level control means.

  According to a second aspect of the present invention, there is further provided a cleaning liquid injection means for injecting the cleaning liquid into a foam shape into the stored water.

  The inventor further proposes two inventions according to claims 3 and 4 having different configurations of the water level control means.

  The Western-style toilet device according to claim 3 is provided with a bellows type trap portion that can be driven upside down at the end of the extended discharge pipe of the bowl portion, and this trap portion is connected to the drainage channel. The apparatus further comprises a turn trap water washing means housed in a place, and the water level control means controls the water level of the water reservoir surface by driving the bellows type trap portion.

  According to a fourth aspect of the present invention, the western-style toilet apparatus further includes a discharge means for discharging water from the outlet toward the discharge pipe extending from the bowl. The water level control means is characterized in that the water level on the surface of the accumulated water is controlled by operating the ejection means and ejecting a predetermined amount of accumulated water from the ejection port toward the discharge pipe.

  According to the Western style toilet device of the first aspect, since the water level of the stored water is moved to a low position while the foam layer is formed on the stored water, the inner surface of the bowl portion can be coated with foam over a wide range. Therefore, the adhesion and generation of dirt can be prevented, and the dirt can be removed.

  According to the second aspect of the present invention, since the cleaning liquid injecting means for injecting the cleaning liquid into a foam state and injecting it into the stored water is provided, it is possible to easily generate foam in the bowl portion.

  The invention according to claim 4 is applied to a so-called siphon-zette type toilet, and has a spout for forcibly ejecting a predetermined amount of accumulated water toward the discharge pipe. Can be moved.

  In particular, if the ejection from the ejection port can be controlled separately from the drainage from the rim portion, the drainage can be performed only by ejection from the ejection port without flowing the cleaning liquid from the rim portion. Easy to adjust. Further, in the case where the ejection from the ejection port and the drainage from the rim portion are performed simultaneously, new foam can be supplied into the bowl portion as the water level is lowered by injecting the foam-like cleaning liquid from the rim portion.

  Embodiments of the present invention will be described below with reference to the accompanying drawings. The present invention reduces the water level by lowering the level of the stored water by lowering the level of the stored water while foam is formed above the stored water in the bowl. Two embodiments having different configurations as the water level control means are shown below.

Embodiment 1

  FIG. 1 is a schematic longitudinal sectional view showing an example of a Western style toilet device of the present invention.

  The Western-style toilet device 1 includes a toilet body 2, a toilet seat 5, a toilet lid 6, a toilet seat 5, and a rotating portion 7 for the toilet lid 6, which are made of resin or ceramics, including a bowl portion 3 and a skirt portion 4. Water (drainage) is always stored as the stored water F in the bowl portion 3 except when draining. The Western-style toilet device 1 has a cleaning liquid injection means 10 configured to inject the cleaning liquid into the bowl portion 3 in the form of foam, whereby a foam layer is formed on the water reservoir Fa as shown in the figure. B can be formed.

  In addition, you may make it form the foam layer B on the water retention surface Fa by another means. For example, instead of injecting the foamed cleaning liquid, only the foam B may be poured after the cleaning water is injected.

  The cleaning liquid injection means 10 includes a cleaning liquid supply device 11 and a fine foam particle generator 12 that mixes fine foam particles into the cleaning liquid in order to inject the cleaning liquid into the bowl portion 3 in the form of foam.

  The cleaning liquid supply device 11 temporarily stores a cleaning liquid made of tap water in the low tank 11a, and discharges a predetermined amount of cleaning liquid from the water discharger 11c to the bowl part 3 through the cleaning liquid channel 11b. It is discharged directly into the bowl part 3 in the direction of the arrow x1, or is discharged from the periphery of the bowl part 3 into the bowl part 3 via a rim part 3a connected to the upper end of the bowl part 3. Reference numeral 11d denotes a cleaning liquid supply valve for supplying and stopping the cleaning liquid from the water pipe into the raw tank 11a.

  One fine foam particle generating device 12 includes a gas mixing part 12a that obtains a gas mixed cleaning liquid by mixing gas into the cleaning liquid supplied into the raw tank 11a, and a check valve that prevents the cleaning liquid from flowing backward from the gas mixing part 12a. 12b, an air pump 12c that pumps the cleaning liquid from a water pipe (not shown) into the low tank 11a, and the low tank 11a. The foamed gas mixed cleaning liquid pumped by the air pump 12c is dissolved in the cleaning liquid under high pressure. A dissolution tank 12d for obtaining a gas-dissolved cleaning liquid, and a foam generation nozzle 12e for generating a fine foam particle by depositing a gas in the gas-dissolved cleaning liquid to obtain a fine foam-particle-containing cleaning liquid.

  As described above, the cleaning liquid is supplied into the bowl portion 3 in the form of bubbles by disposing the foam generating nozzle 12e in the water discharge portion 11c communicating with the bowl portion 3 of the cleaning liquid flow path 11b.

  Further, the western style toilet device 1 includes a turn trap water washing means 20 as a draining means. The turn-trap water washing means 20 includes a trap part 21 and a drive mechanism 22, and the trap part 21 is connected to a discharge pipe 13a and has a trapping hose 21a having a bending flexibility due to a bellows structure, and a trap hose 21a. The drive mechanism 22 is attached to the end member 21b and rotated by driving of a motor (not shown), and the rotation shaft portion 22a. And an arm member 22b for transmitting rotation.

  In the Western style toilet device 1 using such a turn trap flushing means 20, the trap hose 21 a is upward except when draining, and the trapped water F is kept in the trap hose 21 a and the bowl portion 3. ing.

  When the water washing operation is performed, a solenoid valve (not shown) is opened, and the cleaning liquid is poured into the inner surface of the bowl part 3 through the cleaning liquid channel 11b and the water discharger 11c.

  At the same time, in the turn trap rinsing means 20, the rotation shaft portion 22a rotates in the direction of the arrow x2 by driving the motor, so that the rotation of the rotation shaft portion 22a is transmitted to the arm member 22b, and the rotation shaft portion 22a is the center. It rotates in the direction of arrow x2.

  Then, the termination member 21b connected to the arm member 22b pushes down the trap hose 21a downward, so that the trap hose 21a hangs down in the arrow x2 direction, and drainage and filth are discharged to the discharge path. After the filth is discharged, the arm member 22b is rotated in the reverse direction, and the trap hose 21a is returned to the original position, and water is again stored in the bowl portion 3.

  In this embodiment, this turn trap water washing means 20 constitutes a water level control means for lowering the water level of the foam layer B from a high position to a low position. The water level control means includes a main control unit (not shown) constituted by a CPU or the like, and this main control unit detects various timings and performs water level movement control.

FIG. 2 is an explanatory diagram of the principle of changing the water level of the accumulated water F in which the foam layer B is formed in the Western style toilet device 1, FIG. 2 (a) is a high water level, FIG. 2 (b) is an intermediate water level, FIG. 2 (c) is a diagram showing each state of a low water level.

  (A) is the toilet unused state which closed the toilet lid 6, for example, At this time, the stored water F is maintaining the initial (normal) water level. The initial water level of the stored water F may be adjusted according to the amount of the foam B, and is generally used in the initial state so that the foam layer B can coat a wider surface from the high position to the low position of the bowl portion 3. It is desirable to set a little higher than the normal water level.

As described above, the water level of the stored water F is determined by the height of the end portion 21b of the bellows type trap portion 21, so that the trap portion 21 is turned upward in order to obtain a higher water level as shown in FIG. Just keep it higher.

Further, when the trap part 21 is rotated to the positions shown in FIGS. 2B and 2C , a part of the accumulated water F is discharged from the trap part 21, and the water level of the accumulated water F fluctuates to a position corresponding thereto. To do.

  In this way, if the water level of the stored water F is moved from the high position to the low position, the foam layer B also moves to the low position accordingly, so that the foam layer B contacts the inner surface of the bowl portion 3 of the foam layer B accordingly. The part also spreads. As a result, a coating film C of foam B is formed on the inner surface of the bowl portion 3 over a wide range, which is useful for preventing the occurrence of dirt and adhesion.

The above fluctuation of the water level of the stored water F from the position shown in FIG. 2 (a) to the position shown in FIG. 2 (c) is controlled at a timing different from the washing operation. For example, the start of use of the toilet, that is, the opening operation of the toilet lid 6 or the seating on the toilet seat 5 may be performed at a timing detected by a sensor or the like. Further, the water level may be moved at an appropriate timing in the toilet unused time zone after all drainage is performed by a flush operation after the toilet.

  In the former, the inside of the bowl part 3 can be coated before the stool, so that the adhesion of stool by the subsequent stool can be effectively prevented, while the latter can effectively prevent the occurrence of scale in the toilet non-use time zone. If it is allowed to stand for a predetermined time after the water level is lowered, it is possible to easily remove sticking dirt.

  In addition, the water level may be lowered to a completely drained state (FIG. 4 (c) in the second embodiment) without storing water, and even if such a completely drained mode is executed in the toilet unused time zone. Good. By executing such a mode, the foam forms a film on the entire inside of the bowl portion 3 and there is no accumulated water, which makes cleaning much easier.

  It goes without saying that the water level movement timing based on the various timings described above is generated by various detection sensors such as a toilet seat opening / closing sensor and a seating sensor (not shown) and human operations.

  In order to further enhance the prevention of contamination, it is desirable to add a chemical or a detergent to the cleaning liquid.

Embodiment 2

  FIG. 3 is a schematic longitudinal sectional view showing another example of the western style toilet device of the present invention. In addition, since the structure of the toilet body 2 and the cleaning liquid injection unit 10 of the present embodiment are the same as those in the first embodiment, the same reference numerals as those in the first embodiment are given and the description thereof is omitted.

  Moreover, in this invention apparatus 1A, the discharge pipe 13a is extended from the bottom part vicinity of the bowl part 3 to back, is comprised by the toilet bowl main body 2, and has a structure drained to the drainage channel 14 from the terminal end of the discharge pipe 13a. The discharge pipe 13a constitutes a trap part 13, and the trap part 13 can hold the accumulated water F in the bowl part 3 at the same height as the bent part 13b of the discharge pipe 13a. Yes.

  In the present embodiment, the Western style toilet device 1 </ b> A includes the ejection means 30 that causes the water flow to forcibly discharge the accumulated water F in the bowl portion 3. The jetting means 30 supplies and stops water from a jet 31 provided at the bottom of the bowl 3, a water supply pipe 32 that feeds water into the jet 31, and a water pipe (not shown). And a jetting valve 32, and at the time of the water washing operation, the wastewater is jetted toward the bent portion 13b (in the direction of the arrow x3) of the discharge pipe 13a, thereby forcibly causing a siphon action and a part of the accumulated water F It becomes the composition which drains.

  In the present embodiment, the ejection means 30 constitutes a water level control means for lowering the water level of the foam layer B from the high position to the low position.

FIG. 4 is a diagram illustrating the principle of changing the water level of the accumulated water F in which the foam layer B is formed in the western style toilet device 1A . FIG. 4 (a) is a high water level, FIG. 4 (b) a low water level, FIG. (C) is a figure which shows each state at the time of all the drainage.

FIG. 4A shows, for example, a toilet unused state in which the toilet lid 6 is closed, and at this time, the accumulated water F maintains the initial (normal) water level. The initial water level of the stored water F may be adjusted according to the amount of the foam B, and is slightly higher than a general water level so that the foam B can coat a wider surface from the high position to the low position of the bowl portion 3. It is desirable to set to.

Thereafter, as shown in FIG. 4 (b), when the ejection means 30 is operated to forcibly discharge a predetermined amount of the accumulated water F together with the water flow from the ejection port 31, the water level of the accumulated water F is low as well. Move to.

  Thus, in this embodiment, by adjusting and controlling the ejection means 30, the water level of the stored water F can be moved from the high position to the low position, and the foam layer B is also moved to the low position along with this, As the foam layer B moves, the part where the foam layer B contacts the inner surface of the bowl portion 3 also spreads. As a result, a coating film C of foam B is formed on the inner surface of the bowl portion 3 over a wide range, which is useful for preventing the occurrence of dirt and adhesion.

Timing variations from FIG water level 4 (a) to the position in FIG. 4 (b), for example, the start of use of the toilet, that is detected and seated in the opening operation and seat 5 of the toilet lid 6 of the above pooled water F This should be done in Then when the washing operation after toileting, accumulated water F as shown in FIG. 4 (c) is totally drained.

Moreover, after returning to the position of FIG. 4 (a) at an appropriate timing in the toilet unused time zone after all drainage after the toilet, the water level is changed to the position of FIG. 4 (b) . Also good. Further, similarly to Embodiment 1, may be provided complete drainage mode to completely drain the accumulated water to the position of FIG. 4 (c).

  In the toilet apparatus 1A shown in FIG. 3, the water supply pipe 32 dedicated to jetting is provided so that the jetting operation is performed in a path different from the cleaning liquid injection from the rim portion 3a. In the control, the injection of the cleaning liquid from the rim portion 3 is prohibited, and the drainage only by the ejection means 30 can be realized. Therefore, it becomes easy to adjust the water level movement operation.

  Moreover, as shown in FIG. 5, the toilet device 1B which performs the ejection from the ejection means 30 at the same timing as the water injection from the rim | limb part 3a may be sufficient. In addition, about the same structure as FIG. 3 of the toilet device 1B shown in FIG. 5, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  The Western-style toilet device 1B shown in FIG. 5 has a structure in which a water supply path 32 to the spout 31 is formed in a part of the bowl part 3, and a part of the cleaning liquid supplied to the rim part 3a flows into the water supply path 32. Therefore, when the water level is moved, the ejection from the ejection port 31 and the water injection from the rim portion 3a are performed at the same timing.

  Accordingly, the cleaning liquid flows into the bowl portion 3 from the rim portion 3a even during the ejection operation from the ejection port 31 due to fluctuations in the water level. However, since the water flow from the ejection port 31 is strong, the water level is at the position shown in FIG. If the water is moved and the water level is maintained by stopping the jetting in this state, coating with foam B can be realized.

  In such a configuration, when the water level is moved, the foam B can be additionally introduced from the rim portion 3a. Therefore, the water level can be lowered by the siphon action by the ejection means 30, and the new foam B can be introduced into the bowl portion 3. Therefore, the inside of the bowl part 3 can be coated over a wide range with a large amount of foam B.
