Description

TECHNICAL FIELD

The present invention relates to a chamber pot having an apparatus for exhausting bad smell.

BACKGROUND ART

A bathroom is generally installed in a residing space when building a new building so that it can be most easily, conveniently, cleanly used. The bathroom is changing to a rest space departing from providing a simple excretion function, so it needs to equip with a convenience when in use as well as pleasant feeling as important elements.
Most of the bathrooms used for both urine and feces in a bathroom are equipped with chamber pots for the purpose of ensuring that a user who needs to pass urine or to defecate can do it, comfortably sitting on a chamber pot in an easier way.
As the chamber pot is widely used, the cleanness in the bathroom is largely enhanced; however one of the biggest problems in terms of the bathroom with a sealed space lies in that an ammonic bad smell spreads during defecations which is opposed to the cleanness of the bathroom. In case of a public rest room where is relatively less cared, a bad smell might become a main cause that makes a user use it less and make it dirty.
The chamber pot can be considered to help overcome a cleanness problem of a rest room; however a bad smell coming from urine and feces contains ammonic gas a lot of which discharges during defecation into the air in a gaseous phase, so it is almost impossible to prevent the generation of bad smell from spreading into the air a lot while feces drops into water of the chamber pot.
In a trial to resolve the above mentioned problems, a ventilator is installed in a bathroom for the purpose of ventilating the air in the bathroom to the outside, thus maintaining a pleasant environment in the bathroom; however a bad smell widely spreads in the interior of the bathroom and remains therein, and an outward ventilation with a ventilator installed on a wall surface of a bathroom takes a lot of time to ventilate from an inner space of a bathroom. It takes a lot of time until a pleasant environment is recovered, with a bad smell being removed after defecation; however when a bathroom is frequently used, for example, when a bathroom is big-sized, the above mentioned method does not work as it is planned.
In order to resolve the above mentioned problems, there is provided a method of removing smells from the interior of a bathroom with the aid of an air freshener; however in this case it is needed to repeatedly spray an air freshener, which method costs a lot and is harmful to a human body.
In case of a conventional ventilator, a blowing force of it is relatively weak now that it is initially designed to suck in only air, so a bad smell ventilation performance from a bathroom is not good.

DISCLOSURE OF INVENTION

Accordingly, it is an object of the present invention to provide a chamber pot having an apparatus for exhausting bad smell which makes it possible to effectively remove bad smell in such a way that a bad smell rising from the interior of a chamber pot is sucked by way of a fluid spray hole during defecation and is exhausted by way of a fluid discharge passage, thus effectively eliminating bad smell.
It is another object of the present invention to provide a chamber pot having an apparatus for exhausting bad smell which can be easily installed without an additional hole for a bad smell suction being needed and at a lower cost now that a bad smell in a chamber pot can be sucked in by way of a fluid spray hole formed at a chamber pot body while sucking even water in addition to air.
It is further another object of the present invention to provide a chamber pot having an apparatus for exhausting bad smell which does not need a bad smell ventilation pipe since a bad smell exhausting apparatus is installed at a chamber pot body, and an installation cost and a manufacture cost can be significantly reduced.
To achieve the above objects, there is provided a chamber pot having an apparatus for exhausting bad smell which comprises a chamber pot body having a fluid spray hole formed at an upper, inner surface and a fluid discharge passage at its lower side, a chamber pot cover engaged at an upper surface of the chamber pot body in open and close manners, a suction pipe which is connected between the fluid spray hole and the fluid discharge passage, thus sucking in water or air via the fluid spray hole and discharging it by way of the fluid discharge passage, a suction fan assembly which is installed at one side of the suction pipe and generates a suction force, and a switching member which is installed at the chamber pot cover for thereby driving the suction fan assembly.
The suction pipe serves to prevent the reverse flow of bad smell and is equipped with a bad smell exhausting apparatus having a U-shaped pipe at one side with the U-shaped pipe being filled with water.
The suction fan assembly comprises a fan housing connected to the suction pipe, a driving motor fixed in the interior of the fan housing, and a suction fan fixed at a rotary shaft of the driving motor and generating a suction force.

FIG. 1 is a side view illustrating a chamber pot equipped with a bad smell exhausting apparatus according to an embodiment of the present invention. FIG. 2 is a cross sectional view illustrating a chamber pot equipped with a bad smell exhausting apparatus according to an embodiment of the present invention.
A chamber pot according to the present invention comprises a chamber pot body 10, a water tank 20 supplying washing water into the interior of the chamber pot body 10, a chamber pot cover 30 hinged to an upper side of the chamber pot body 10, and a bad smell exhausting apparatus 40 which is installed at the chamber pot body 10 and starts ventilating a bad smell coming from the interior of the chamber pot body 10 at the moment a user sits on the chamber pot cover 30.
The chamber pot body 10 comprises a plurality of fluid spray holes 12 formed along a surrounding portion of an upper, inner surface, through which fluid spray holes 12 the water stored in the water tank 20 is sprayed into the interior of the chamber pot body 10, thus washing the interior of the chamber pot body 10.
Along a surrounding portion of the upper, inner side of the chamber pot body 10 is formed a water circulation passage 14 communicating with the plurality of the fluid spray holes 12, the water circulation passage being connected to the water tank 20 and the water supply passage 16, respectively.
At a lower side of the chamber pot body 10 is formed a fluid discharge passage 18 for the purpose of discharging the water flown into the chamber pot body 10 toward a sewage disposal tank along with sewage.
One side of the chamber pot cover 30 is hinged to a hinge connection part 32 formed at an upper side of the chamber pot body 10, so the chamber pot cover 30 comes into contact with the upper surface of the chamber pot body 10, and at a lower surface of the chamber pot cover 30 is engaged a support member 34 coming into contact with an upper surface of the chamber pot body 10.
In the water tank 20, a water supply pipe 22 supplying water is connected vertically, and at the water supply pipe 22 is installed a float 24 closing the water supply pipe 22 when the water supplied into the interior of the water tank 20 reaches a certain level, and at an entrance of the water supply passage 16 is installed a rubber valve 26 opening and closing the water supply passage 16, and the rubber valve 26 is connected with a lever by way of a chain 28, thus opening and closing the water supply passage 16 depending on an operation of the lever.
As shown in FIG. 3, the bad smell exhausting apparatus 40 comprises suction pipes 42 a and 42 b connected between the fluid spray hole 12 and the fluid discharge passage 18, a suction fan assembly 44 which is installed at one side of the suction pipe 42 for the sake of generating a suction force, and a switching member 46 which is installed at an underneath of the chamber pot cover 30 and drives the suction fan when a user sits on the chamber pot cover 30.
The suction pipe 42 a, 42 b comprises a first suction pipe 42 a between one side of the water circulation passage 14 connected with a plurality of the fluid spray holes 12 and a suction port of the suction fan assembly 44, and a second suction pipe 42 b which is connected between a discharge port of the suction fan assembly 44 and a fluid discharge passage 18. The suction pipes 42 a and 42 b are characterized in that the air or water in the interior of the chamber pot body 10 is sucked via the fluid spray holes 12 at one side of the water circulation passage 14 connected to a plurality of the fluid spray holes 12, and the air or water is discharged to the fluid discharge passage 18.
The suction pipes 42 a and 42 b can be integrally manufactured when manufacturing the chamber pot body 10 or can be separately manufactured and can be installed at the chamber pot body 10.
The suction pipe 42 a, 42 b can be installed at one side of the left and right sides of the chamber pot body 10, in other words, the suction pipe 42 a, 42 b can be at one side of the left and right sides of the chamber pot body 10 depending on a place where the chamber pot body 10 is installed.
The suction pipes 42 a and 42 b suck in the air from the chamber pot body 10 along with the water which is sprayed from via the fluid spray holes 12, and the water and air pass through the suction pipes 42 a and 42 b, and the water sucked into the suction pipes 42 a and 42 b serves to wash the suction fan assembly 44 and is filled into the U-shaped pipe 50 which will be described later.
Between the second suction pipe 42 a and the fluid discharge passage 18 is installed a U-shaped pipe 50, and since the water is always filled in the interior of the U-shaped pipe 50, it is possible to prevent the bad smell from reversely flowing into the chamber pot body 10 via the suction pipe 42.
The U-shaped pipe 50 is rotatably connected with the second suction pipe 42 b and is engaged so that it can move as much as a certain width in the up and down directions.
In other words, a certain assembly margin occurs when engaging the suction pipes 42 a and 42 b to the chamber pot body 10. For the purpose of offsetting the above mentioned margin, the U-shaped pipe 50 is rotatably connected and is engaged to be linearly movable as much as a certain width.
The engaging structure between the U-shaped pipe 50 and the second suction pipe 42 b can be implemented in various forms, for an example, a U-shaped pipe 50 is inserted into at an end portion of the second suction pipe 42 b, and a sealing member 52 is sealingly engaged between the second suction pipe 42 b and the U-shaped pipe 50, and a cover member 54 can be bolt-engaged at the second suction pipe 42 b.
As shown in FIG. 4, the suction fan assembly 44 comprises a fan housing 60 connected to the suction pipe 42, a driving motor 66 fixed in the interior of the fan housing 60 and a suction fan 68 fixed at the rotary shaft 78 of the driving motor 66 and generating a suction force.
The fan housing 60 comprises a suction space 70 sucking in air or water, a suction fan installation space 72 in which the suction fan 68 is rotatably arranged, and a driving motor space 74 in which the driving motor 66 is installed, all the above-mentioned spaces being partitioned by means of partition walls 62 and 64, respectively.
At a side surface of the suction space 70 is formed a suction port 80 connected with the suction pipe 42, and at a side surface of the blowing fan installation space 72 is formed a discharge port 82.
The suction space 70 and the suction fan installation space 72 is partitioned by the first partition wall 62, and at the first partition wall 62 is formed a suction passage 76. The suction fan installation space 72 and the driving motor installation space 74 are partitioned by the second partition wall 64, and at the second partition 64 is formed a rotary shaft through hole 84 through which the rotary shaft 78 of the driving motor 66 passes, and at a periphery of the rotary shaft through hole 84 is installed the sealing member 86 which seals the water from flowing into the driving motor via the rotary shaft through hole 84.
The sealing member 86 might be made of various materials such as a rubber material or something which can interrupt the input of water into the driving motor.
The suction fan 68 is so formed that water or air can be sucked in via its central portion and is discharged past its outer surface, in other words, the water or air sucked into the suction space flows toward the center of the blowing fan via the suction passage, and the water or air sucked toward the central portion by means of the blowing fan is discharged past the outer surface of the blowing fan.
The suction fan 68 has a structure helping it to rotate at a high speed, in other words, at about 8000 RPM. As the suction fan 68 rotates at a high speed, even when the conventional fluid spray hole 12 is even smaller, it can generate enough suction force, thus facilitating a good bad smell suction performance.
Since the bad smell exhausting apparatus according to the present invention sucks air as we as water, it is equipped with a suction fan with a suction force strong enough to suck in air and water.
In case of the suction pipes 42 a and 42 b, the distance from the fluid spray holes through which the bad smell is sucked to the fluid discharge passage through which the bad smell is ventilated is shortest, so the discharging of the bad smell is performed faster, and the bad smell ventilation performance can be enhanced a lot.
The switching member 46 is installed at an underneath of the chamber pot cover 30 or at an upper surface of the chamber pot body 10. When a user sits on the chamber pot cover 30, it starts operating by means of the sitting pressure. It might be formed a certain switch which can generate a signal when receiving a pressure.
The operations of the chamber pot having an apparatus for exhausting bad smell according to an embodiment of the present invention will be described.
When a user sits on a chamber pot cover 30, the switching member 46 operates by means of a pressure applied to the chamber pot cover, and electric power is supplied to the driving motor 66 of the suction fan assembly 44 as the switching member 46 operates. Afterward, the driving motor 66 is driven, and the suction face 68 connected with the driving motor 66 rotates, and suction force occurs at the suction pipe 42.
Afterward, the air is sucked into the suction pipe 42 from the interior of the chamber pot body 10 by way of the fluid spray holes 12 formed at the chamber pot body, and the air sucked into the suction pipe 42 is ventilated via the fluid discharge passage 18.
When a user passes urine or defecates sitting on a chamber pot body 10, the bad smell rising from the interior of the chamber pot body 10 is ventilated toward the fluid discharge passage 18 via the fluid spray holes 12, thus consequently removing the bad smell.
At this time, even when the water stored in the water tank 20 via the fluid spray holes 12 is discharged into the interior of the chamber pot body 10, the water flows into the suction pipe 18. In this case, the water sucked into the suction pipe 18 is discharged by means of a suction force of the suction fan 68 and moves toward the fluid discharge passage 18.
Here, at a fan housing 60 of the suction fan assembly 44 is installed a sealing member 86, so the water passing through the suction fan 68 can be interrupted from flowing into the driving motor 66.
The preferred embodiments of the present invention have been described; however it is obvious that the scopes of the present invention is not limited to the disclosures, and various changes or modifications by an ordinary person skilled in the art by using the basic concepts of the present invention belong to the scopes of the present invention.
