Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a Western-style toilet, and although not particularly limited, it is suitable for installation in public toilets such as parks, highway parking, department stores, hospitals, movie theaters, etc. used by many unspecified users. Related to Western style toilets.
[0002]
[Prior art]
In recent years, western toilets have been developed for toilets, and almost all toilets in general households and hotels have become Western toilets, and Western toilets have begun to be used in public toilets.
However, in this Western style toilet, the toilet seat is in direct contact with the exposed back of the crotch root, which can cause discomfort to the user, especially in public toilets, and can be unsanitary. .
[0003]
Therefore, in a Western-style toilet installed in such a public toilet, for example, when the user is seated on the toilet seat, the user rests on the toilet seat, and the user's exposed crotch root side is directly on the toilet seat. Seat paper (toilet seat cover) to prevent contact is prepared separately from toilet paper, and a seat paper automatic supply device that automatically supplies such sheet paper on the toilet seat is installed in a Western style toilet, For the toilet seat, the main body is formed in a hollow shape and a large number of small holes are opened on substantially the entire upper surface thereof, and air is blown out from the small holes by the blower device disposed in the sheet paper automatic supply device, or A sheet paper suction structure that sucks and holds the sheet paper that is drawn out on the toilet seat, or that adsorbs onto the toilet seat (Japanese Patent Laid-Open No. 5-137,666) It has been proposed.
[0004]
However, in the method of preparing the seat paper separately from the toilet paper, the unit price of the seat paper itself is higher and the installation cost is higher than the toilet paper, and when this is adopted particularly in a public toilet, for example, a department store, It is possible to deal with facilities that have a relatively large number of people compared to the number of users, such as hospitals and movie theaters, but there are many users such as parks and parking on highways. In the case of a facility, there is a problem that the sheet paper is quickly sold out, and eventually many users cannot use the sheet paper.
[0005]
In addition, for the seat paper adsorbing structure, the surface of the toilet seat is easily soiled because a large number of small holes are formed on the entire upper surface of the hollow toilet seat. Foreign matter can easily get stuck in the small holes, and it is not easy to remove the toilet seat from the toilet and clean it, so sometimes the seat paper suction mechanism may not work, and the sheet paper will run out of stock. In some cases, the user may feel uncomfortable.
[0006]
In addition, in order to cleanly use the toilet seat of a Western-style toilet, the toilet paper itself is also used as a simple sheet paper. For example, Japanese Patent Laid-Open No. 7-241,257 discloses a toilet that is drawn downward. A simple toilet seat cover forming apparatus has been proposed which has a scissor roller for scoring the toilet paper across the front and back sides of the paper, and Japanese Patent Laid-Open No. 2000-287,887 discloses a plurality of push holes in the toilet seat. It has been proposed that a part of the toilet paper that has been formed and cut is pushed into these push holes, and the toilet paper cut thereby is used as a simple toilet seat cover.
[0007]
However, in the former simple toilet seat cover forming apparatus, the shape of the toilet seat cover formed by the brazing roller is always constant, whereas the toilet seat of a Western-style toilet bowl has a horseshoe shape with slightly different outline shapes. In addition to various shapes such as an elliptical shape, there are several sizes, too, and toilet seat covers that are molded only in a uniform shape cannot accommodate these many shapes of toilet seats, There is a problem that a molding apparatus must be prepared in accordance with the shape of each toilet seat, and the molding apparatus is too expensive.
[0008]
In the latter method of using the cut toilet paper as a simple toilet seat cover, it is necessary to form a plurality of push holes for pressing and fixing a part of the cut toilet paper into the toilet seat. There is a problem that dirt and foreign matter are easily clogged in the push-in hole, and the toilet seat cannot be easily removed from the toilet bowl and cleaned, so that it tends to become dirty.
[0009]
[Problems to be solved by the invention]
Therefore, as a result of intensive studies on means that can solve various problems in the conventional Western-style toilet described above, the present inventors formed open hollow portions that open upward on the left and right sides of the toilet seat. Toilet paper that is detachably closed along the general surface of the toilet seat and is provided with a ventilation lid having a plurality of ventilation holes in the opening hollow portion, and is cut on the ventilation lid by sucking the opening hollow portion by an air intake means By adsorbing and holding toilet paper such as tissue paper, it is possible to use the toilet paper provided and portable tissue paper as a simple toilet seat cover, and the toilet seat tends to be unsanitary The present inventors have found that the problem can be solved and that odor from the toilet can be removed by suction, and the present invention has been completed.
[0010]
Therefore, the object of the present invention is to use toilet paper such as attached toilet paper and portable tissue paper as a simple toilet seat cover, and without causing the toilet seat to become unsanitary, and from the toilet bowl. The object is to provide a Western-style toilet that also draws off the odor of the air and exerts a deodorizing function.
[Means for Solving the Problems]
That is, the present invention is a Western-style toilet having a toilet and a toilet seat attached to the periphery of the opening of the toilet so as to be openable and closable, and the left and right sides of the toilet seat have opening hollow portions that open upward. The opening hollow portion is detachably closed along the general surface of the toilet seat and provided with a ventilation lid having a plurality of ventilation holes, and the opening hollow portion is sucked by the intake means on the ventilation lid. This is a Western style toilet that absorbs and holds toilet paper. Here, the general surface of the toilet seat refers to a surface that forms a natural contour shape of a three-dimensional toilet seat.
[0012]
In the present invention, the portions where the opening hollow portions that open upward are formed on the left and right side portions of the toilet seat (in other words, the region occupied by the opening portions on the left and right side portions of the toilet seat) block the opening hollow portion. There is no particular limitation as long as it is a position that can hold toilet paper such as cut toilet paper or tissue paper placed on the upper surfaces of the left and right sides of the toilet seat by the suction force of air passing through the vent hole of the vent lid, If it is too wide, the vent lid will inevitably become large, and it will take a lot of time to clean the vent lid by removing this vent lid, and conversely, if it is too narrow, it will inevitably ventilate. Preferably, the user sat down on the toilet seat because the lid would be smaller and the toilet paper could not be securely held in the necessary areas on the upper surfaces of the left and right sides of the toilet seat. To about the crotch root back to the contact portion of the user, the length of its sides longitudinal direction 10 to 40 cm, more preferably in the range of 20 to 30 cm.
[0013]
In addition, each of the opening hollow portions provided in the side portion of the toilet seat has only to be opened toward at least the upper side of the toilet seat side portion, but may be opened toward the upper side and the inner side of the toilet seat side portion. At this time, the vent lid is provided with an inner vent hole inwardly in a portion where the vent lid closes the inner side of the opening hollow portion. The function as a suction port can be exhibited and a more excellent deodorizing function can be imparted.
[0014]
Furthermore, with respect to the plurality of vent holes formed in the vent lid, if the toilet paper placed on the vent lid can be surely sucked and held by the flow of air sucked through the vent holes, for example, the length of the vent holes can be increased. In order to hold the toilet paper more securely, it may be formed or arranged in any way, such as by forming a relatively large through hole in the front and rear positions. It is good to comprise with many small holes arrange | positioned substantially uniformly over the substantially whole surface of a ventilation lid.
[0015]
Furthermore, with regard to means for detachably attaching the vent lid to the opening edge of the opening hollow portion, the vent lid can be securely fixed to the opening edge of the opening hollow portion, and the user acting on the vent lid can be fixed. There is no particular limitation as long as the load can be reliably applied and the vent lid can be easily attached to and detached from the opening edge of the opening hollow portion. For example, the opening edge of the opening hollow portion may be outside or inside the wall. The upper and lower halves form a step with a lower half and the inner or outer half has a lower step and the outer or inner half of the wall has a lower step and the inner or outer half has a higher step. A fitting method in which the step portion on the vent lid side is fitted to the step portion on the opening edge side of this, and in this fitting method, a pressure fitting method in which the elasticity of the members is used to fit each other under pressure, , Stand upright on the vent lid side and / or the bottom side of the open hollow, A column system that applies the load of the user acting on the vent lid by the column, and in this column system, the elasticity of the member is used between the tip of each column and the part where the column tip contacts. A column fitting method that forms uneven portions that fit together under pressure, a magnet method that incorporates magnets that attract each other on the vent lid side and the bottom side of the opening hollow portion, and a magnet method that uses the attractive force of this magnet, Furthermore, the combination system etc. which comprise combining these each system suitably can be illustrated.
[0016]
In the present invention, the toilet paper is adsorbed and held on the vent lid by sucking the open hollow portions formed on the left and right sides of the toilet seat with the suction means, and the toilet paper is used as a simple toilet seat cover. The toilet seat may be of a horseshoe shape or an elliptical shape, and may be solid or hollow.
[0017]
Here, there is no particular limitation on the means for forming the opening hollow portions on both the left and right sides of the toilet seat. For example, when the toilet seat is formed of a solid body, through holes are formed in necessary areas on both the left and right sides. Then, a bottom plate may be provided on the lower surface side to form the bottom part, or an open hollow part having a bottom part may be drilled from the beginning, and when the toilet seat is formed of a hollow body It is good also as an opening hollow part which forms an opening in the upper part of the both right-and-left both sides, an upper direction, and an inner side, and has an opening part.
[0018]
Further, in the present invention, the opening hollow portions formed on the left and right side portions of the toilet seat may exist independently, but preferably are connected to each other by a communication path, and the left and right opening hollow portions are connected by an intake means. It is good to be able to suck at the same time. In this case, if the toilet seat itself is formed of a hollow body, and openings are formed on both left and right sides thereof to form the opening hollow portion, the opening hollow portions located on both the left and right sides of the toilet seat and the open hollow portions are connected. A passage is formed at the same time.
[0019]
In the present invention, the suction means for sucking the opening hollow portion is not particularly limited as long as it can suck the air in the opening hollow portion, for example, a relatively small blower device having a fan and an intake / exhaust port, A blower device comprising a relatively small fan having an air inlet and an air outlet, a connection line having one end connected to the air inlet of the fan and the other end connected to the opening hollow portion, and relatively Relatively large fans having large inlets and outlets, and each opening hollow part formed in a plurality of Western-style toilets having one end connected to the inlet of the fan and a plurality of branch lines on the other end side For example, a relatively large intake facility provided with an intake line connected to the.
[0020]
Also, the mounting position of these intake means is not particularly limited. For example, a relatively small blower device is directly incorporated in the toilet seat, disposed adjacent to the toilet, or outdoors. In addition, when a plurality of Western-style toilets are used, a relatively large intake device may be provided outdoors. In particular, when a relatively small blower device is directly incorporated in the toilet seat, a communication passage is formed in the toilet seat to connect the open hollow portions on both the left and right sides, and the communication passage is disposed in the communication passage so that It is desirable that the open hollow portion be constructed so that it can be sucked simultaneously.
[0021]
Further, in the present invention, when the air intake means is directly incorporated in the toilet seat or disposed adjacent to the toilet seat, the air holes are formed when sucked by the air intake means in the open hollow portions formed on the left and right sides of the toilet seat. Deodorizing agent such as activated carbon, zeolite, silica gel, breathable deodorizing sponges carrying other odor adsorbing substances, and those odor adsorbing substances filled in the breathable bag at a more leeward position It is preferable that the (deodorizing means) be disposed so as to be replaceable, and this prevents odor from being trapped in the private room of the toilet.
[0022]
In the present invention, the intake means may be driven / stopped by attaching a drive switch of the blower device and manually operating when using the Western-style toilet with this drive switch. The means may be incorporated with a control means comprising a sensor or the like for detecting the movement of the user of the western-style toilet and driving the intake means, and stopping the intake means, whereby the user himself operates the drive switch for the intake means. This is desirable from the standpoint of hygiene and deodorization.
[0023]
There are no particular restrictions on this control means, but, for example, an entrance sensor that detects a user who has entered the toilet room, and that a predetermined time, for example, about 5 to 7 seconds has elapsed since the user got up from the toilet seat. For example, a control means that is provided with a toilet seat sensor that is driven by a user detection signal of the entrance sensor and detects and stops a toilet seat use end signal of the toilet seat sensor can be exemplified.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be specifically described based on examples shown in the accompanying drawings.
[0025]
1 and 2, a western-style toilet according to an embodiment of the present invention is shown. This Western-style toilet includes a toilet 1, a toilet seat 2 that is formed in a substantially oval shape with a hollow body, and is attached to the periphery of the opening of the toilet 1 so as to be openable and closable, and a lid 3. The left and right sides of the toilet seat 2 are formed with an opening hollow portion 4 that opens upward and opens upward. The opening hollow portion 4 is detachable along the general surface of the toilet seat 2. A ventilation lid 5 having a large number of small holes (ventilation holes) 6 that are closed and arranged substantially uniformly over the entire surface is provided. Further, in the rear inner space of the toilet seat 2, a fan 7a and the above-mentioned A blower device that has a pair of intake ports 7b that open in the direction of each open hollow portion 4 and an exhaust port 7c that opens toward the outside of the toilet seat 2 and sucks air in each open hollow portion 4 ( (Intake means) 7 is provided.
[0026]
In this embodiment, the means for removably attaching the vent lid 5 to the opening edge of the opening hollow portion 4 is arranged inside the wall of the opening edge of the opening hollow portion 4 as shown in FIG. A step 8a is formed in which the outer half is lower and the outer half is lower, and a step 8b in which the inner half of the wall is lower and the outer half is higher is formed on the peripheral edge of the vent lid 5. A step 8b on the ventilation lid 5 side is fitted to the step 8a on the portion side under pressure by utilizing the elasticity of the member, and the bottom portions of the ventilation lid 5 and the opening hollow portion 4 are opposed to each other. The support columns 4a and 5a are erected, and the recesses 5b and the protrusions 4b that fit together are formed at the tip portions of the support columns 4a and 5a, and the ventilation lid 5 is fitted to the opening edge of the opening hollow portion 4. At this time, the concave portion 5b and the convex portion 4b are fitted to each other, whereby the user's load acting on the vent lid 5 is loaded by the support columns 4a and 5a. It has become so.
[0027]
Moreover, the opening hollow part 4 formed by forming an opening in the right and left both sides of the toilet seat 2 formed entirely as a hollow body is in communication with each other in the internal space (communication path) of the toilet seat 2, When the blower device 7 disposed in the rear inner space of the toilet seat 2 is driven, the open hollow portions 4 on both the left and right sides of the toilet seat 2 are simultaneously sucked through the inner space of the toilet seat 2. .
[0028]
Further, in this embodiment, as shown in FIG. 2, each of the opening hollow portions 4 has a breathable deodorizing position at a position where it is leeward from the small hole 6 when sucked by the blower device 7. A deodorizing agent (deodorizing means) 9 made of a sponge is disposed so as to be replaceable. As a result, the odor in the air sucked from the numerous small holes 6 of the ventilation lid 5 by driving the blower device 7 is removed from the deodorizing agent. Air that is adsorbed and deodorized when passing through the agent 9 is sucked into the air inlet 7b of the blower device 7 and exhausted to the outside through the air outlet 7c.
[0029]
Furthermore, in this embodiment, the blower device 7 includes an entrance sensor that detects a user who has entered the toilet room, and a predetermined time, for example, about 5 to 7 seconds has elapsed since the user got up from the toilet seat 2. A toilet seat sensor for detecting the toilet seat, which is driven by a user detection signal of the entrance sensor, and a control means (not shown) for detecting and stopping the toilet seat use end signal of the toilet seat sensor.
[0030]
Therefore, when the user enters the toilet room to use the western toilet, the blower device 7 starts to drive when its control means is activated, and thus the toilet seat 2 is moved to the toilet seat 2. Is sucked from a large number of small holes 6 of the vent lid 5, passes through the open hollow portions 4 on both the left and right sides of the toilet seat 2, and further passes through a deodorizer 9 provided leeward of the large number of small holes 6, An air flow is formed which is sucked from the air inlet 7b of the device 7 and exhausted to the outside through the air outlet 7c.
[0031]
In this state, the user cuts the toilet paper into a predetermined length, for example, a length that the user's exposed crotch root is in contact with the left and right sides of the toilet seat 2, and the cut toilet paper 10 is cut into the toilet seat. When placed on the vent cover 5, the cut toilet paper 10 is adsorbed and fixed on the vent cover 5, as shown in FIG.
