Description

{Manure drying toilet that can generate electricity using natural air circulation}

The present invention relates to a waste drying toilet that can naturally dry waste using natural air circulation and generate power.

Toilets are convenience facilities for disposing of human waste, and are generally divided into flush toilets and flush toilets.

A flush toilet is a method of disposing of sewage in a toilet by flushing a certain amount of water using water collected in a water tank, and is widely used in homes, apartments, and public facilities.

A quick-fill toilet is a method of accumulating waste in a storage space such as a septic tank installed under the toilet or sealed concrete, and periodically disposing of it all at once using a waste collection vehicle. It can be installed in outdoor areas such as rice fields, fields, vacant lots, and construction sites. It is installed and used.

These quick-fill toilets have a problem in that sewage accumulates in the storage space and is left unattended for a certain period of time, generating a foul odor, and causing discomfort to users because the generated foul odor is not properly circulated.

To solve this problem, there have been conventional methods of discharging bad odors by installing a separate exhaust facility using power in the storage space below the toilet or inside the toilet.

However, these methods of installing separate exhaust facilities have the problem of being very cumbersome and expensive to install, and difficult to use in places where electricity is not supplied.

Accordingly, there is a need for a quick-fill toilet that can be installed with a simple structure, uses natural air circulation, can effectively prevent bad odors in the toilet at low cost, and can also generate electricity.

The excrement drying toilet (hereinafter referred to as toilet) 100 of the present invention includes an upper body 110, a lower body 120, an exhaust pipe 130, an exhaust fan 140, and a staircase 150.

The upper body 110 has a space inside which the user can enter, and a door 112 through which the user can enter and exit is formed at the front. A toilet 111 is provided inside the upper body 110. The toilet 111 may be of various forms, such as a conventional type, a flush type, or a flush type.

In addition, the upper body 110 is divided into an internal space so that two or three people can use it simultaneously, depending on the size of the toilet, and a toilet 111 is installed in each partitioned space, or an upper body manufactured in a size for one person A plurality of main bodies 110 can be connected and installed as needed.

The lower body 120 is installed below the upper body 110 and stores excrement discharged from the toilet 111. Manure can be stored for a certain period of time and then periodically collected by a waste disposal vehicle and purified or used as compost.

The exhaust pipe 130 is installed vertically on the outside of the upper body 110 to contact the outside air, and its lower end is installed to communicate with the lower body 120.

The exhaust fan 140 is installed at the top of the exhaust pipe 130. Inside the exhaust fan 140, a blade (not shown) capable of axial rotation and a bearing (not shown) are installed to enable rotation of the blade. As the exhaust fan 140 rotates, the air inside the exhaust pipe 130 is discharged to the outside, allowing bad odors inside the toilet 100 to be quickly discharged.

A staircase 150 may be installed on one side of the lower body 120. When the upper body 110 is installed higher than the ground, the user can enter and exit the restroom 100 through the stairs 150. In contrast, when the upper body 110 is installed at the same height as the ground, the lower body 120 can be buried in the ground without the stairs 150.

Referring to Figures 1 and 2, the exhaust pipe 130 is installed on the outside of the upper body 110 to come into contact with the outside air.

The exhaust pipe 130 includes a first vertical duct 131, a venturi-type connector 132, a second vertical duct 133, a fan unit 137, a generator 138, a heating jacket 134, and a reflection plate 136. ) includes.

The first vertical duct 131 is connected to the lower body 120 and the air inside the lower body 120 is directly introduced.

The venturi-type connector 132 is connected to the first vertical duct 131 and has a diameter smaller than that of the first vertical duct 131.

The second vertical duct 133 is connected to the venturi-type connector 132 and has a larger diameter than the venturi-type connector 132. The second vertical duct 133 may be formed to have the same diameter as the first vertical duct 131.

The fan unit 137 is installed inside the venturi-type connector 132 and includes one or more fans. The generator 138 is connected to the fan unit 137 and produces electrical energy by rotating the fan.

Due to this structure, the air flowing into the first vertical duct 131 from the lower body 120 quickly passes through the venturi-type connector 132 with a smaller diameter and rotates the fan of the fan unit 137, thereby rotating the fan of the fan unit 137. Electrical energy can be produced by the generator 138 connected to the fan unit 137. In order to more reliably demonstrate the performance of generating electrical energy by driving the generator 138 by air flowing from the lower body 120, a plurality of fans may be connected in series.

The heating jacket 134 is installed in a cylindrical shape to surround the outer peripheral surface of the second vertical duct 133. The heating jacket 134 is formed of a light-transmissive member, allowing external sunlight to flow into the heating jacket 134 through the heating jacket 134. The heating jacket 134 may be formed so that the inside of the heating jacket 134 is not visible from the outside in consideration of aesthetics.

The heating jacket 134 is filled with air inside and can be heated by sunlight, and the heated air can transfer heat to the second vertical duct 133. To this end, the second vertical duct 133 surrounded by the heating jacket 134 is formed of a light-transmissive member so that sunlight flowing through the heating jacket 134 sufficiently flows into the second vertical duct 133. can do.

The reflecting plate 136 is installed vertically in an arc shape to surround the outer peripheral surface of the heating jacket 134 at a predetermined angle, and is made of a metal material such as aluminum or stainless steel, and its surface is designed to reflect solar heat more effectively. The inner side is made of reflective material. The reflection plate 136 is rotatably supported by a rotational coupling portion 135 connected to the second vertical duct 133 and can be rotated along the outer peripheral surface of the heating jacket 134.

The reflection plate 136 reflects or refracts the light flowing in through the heating jacket 134, allowing sunlight to be sufficiently transmitted to the inside of the second vertical duct 133.

When the user manually adjusts and positions the direction of the reflective plate 136 of this structure according to the direction in which the sun shines, solar heat is concentrated and reflected by the reflective plate 136, thereby forming the heating jacket 134 and the second The air between the vertical ducts 133 is heated more quickly.

Sunlight transmitted into the second vertical duct 133 through the heating jacket 134 heats the air inside the second vertical duct 133 by the greenhouse effect, causing air circulation due to the difference in air density. In this process, bad odors in the toilet 100 are discharged to the outside and excrement stored in the lower body 120 is dried to enable natural decomposition.

Hereinafter, the process of discharging bad odor and drying excrement by air circulation in the toilet 100 of the present invention will be described with reference to FIGS. 1 to 3.

When the second vertical duct 133 is heated through the heating jacket 134 or sunlight flows into the second vertical duct 133, the internal temperature of the exhaust pipe 130 increases and the air within the exhaust pipe 130 is heated. do. Heated air rises and can be discharged to the outside.

Due to the pressure difference due to air rise, as shown by the arrow in FIG. 3, the air in the lower body 120 flows into the exhaust pipe 130, the air in the upper body 110 flows into the lower body, and the outside air flows into the upper body. (110) A moving air circulation is created.

That is, in the toilet 100 of the present invention, air circulation such as external air -> upper body 110 -> lower body 120 -> exhaust pipe 130 -> discharge of air to the outside occurs repeatedly.

Accordingly, the bad odor caused by the excrement in the lower body 120 is discharged to the outside without flowing into the upper body 110, and fresh air from the outside is supplied into the upper body 110, thereby eliminating the bad smell.

Additionally, during the air discharge process, the moisture contained in the manure may dry out and the manure may break into small pieces.

In addition, as sunlight flows in through the heating jacket 134 and the reflecting plate 136, the temperature of the excrement in the lower body 120 increases, causing the excrement to dry and microorganisms to easily reproduce, causing active decomposition.

As described above, the toilet 100 of the present invention has a simple structure and effectively removes bad odors and enables drying and decomposition of excrement without power supply.

Referring to FIG. 4, a communication pipe 121 may be installed vertically at the lower part of the toilet 111 to block the inflow of air so that the air inside the lower body 120 does not easily flow into the upper body 110.

At this time, the communication pipe 121 is formed in a trumpet shape whose diameter gradually increases from top to bottom, and a plurality of holes 121a are formed radially through the outer peripheral surface of the communication pipe 121 along the circumferential direction.

In this way, when the communication pipe 121 has a trumpet shape, the excrement does not easily reach the inner surface of the communication pipe 121 while falling into the interior of the lower body 120 through the toilet 111, so the communication pipe 121 is exposed to excrement. It is not easily contaminated and is kept clean.

The plurality of holes 121a formed in the communication pipe 121 are formed to slope downwardly from the inside to the outside of the communication pipe 121, and the internal air of the upper body 110 passes through the communication pipe 121 through the plurality of holes 121a. It flows into the interior of the lower body 120 through.

In this state, when the air in the exhaust pipe 130 is heated, the air inside the lower body 120 naturally flows into the exhaust pipe 130 and is discharged to the outside, and the odor does not easily flow back toward the upper body 110. .

A cone-shaped dispersion member 122 may be installed on the inner floor of the lower body 120 in accordance with the position of the communication pipe 121 installed at the lower part of the toilet 111 (see FIG. 1).

Due to this dispersion member 122, the water and excrement that fall into the interior of the lower body 120 along the communication pipe 121 are widely dispersed to the surroundings along the slope of the dispersion member 122, causing the excrement to accumulate more evenly.

FIG. 5 is a schematic cross-sectional view showing another embodiment of the exhaust pipe of FIG. 2.

In this embodiment, a plurality of contact members 160 in contact with the outer surface of the second vertical duct 133 are formed on the inner surface of the heating jacket 134, spaced apart in the longitudinal direction.

The contact member 160 extends in a shape that gradually becomes narrower from the inner surface of the heating jacket 134 to the outer surface of the second vertical duct 133, and the end of the contact member 160 is connected to the second vertical duct 133. is contacted over a predetermined area.

A plurality of openings 161 spaced apart at predetermined intervals may be formed on the surface of the contact member 160. The contact member 160 is hollow and has a space inside, and air heated inside the contact member 160 can flow through the opening 161.

The contact member 160 is made of a metal material with good thermal conductivity and transfers heat transmitted by sunlight to the second vertical duct 133, causing the second vertical duct 133 to heat up quickly.

In addition, the opening 161 formed in the contact member 160 allows air around the contact member 160 heated by sunlight to flow to other parts, so that the inner surface of the heating jacket 134 is heated more quickly. Allow it to heat up.

In the bathroom of this embodiment, the heat and air of the heating jacket 134 heated by sunlight are more easily and quickly transferred to the second vertical duct 133 by the contact member 160 formed on the inner surface of the heating jacket 134. This allows for smoother air circulation inside the bathroom.

Figure 6 is a schematic cross-sectional view showing a toilet 200 according to another embodiment of the present invention.

The toilet 200 of this embodiment includes an upper body 210, a lower body 220, an exhaust pipe 230, an exhaust fan 240, and a staircase 250.

The upper body 210, lower body 220, exhaust pipe 230, exhaust fan 240, and stairs 250 are the upper body 110, lower body 120, exhaust pipe 130, and Since it has the same configuration as the exhaust fan 140 and the stairs 150, detailed description will be omitted.

An accommodating space is formed inside the lower body 220 to store excrement, and a hot air pipe 226 having an air inlet 226a and an air outlet 226b is installed at the bottom of the accommodating space.

On one outer side of the lower body 220, a blowing fan 224 is installed at the air inlet 226a of the hot air pipe 226 and supplies warm air to the inside of the hot air pipe 226, and is installed at the air inlet 226a and An electric heater 225 is installed between the blowing fans 224 to heat the air.

At this time, the hot air pipe 226 is installed along the perimeter of the inner floor of the receiving space, and one end of it protrudes to the outside of the lower body 220 so that the air inlet 226a is connected to the blower fan 224 and the electric heater 225. It is installed to face one side, and the other end is installed to face the lower part of the exhaust pipe 230.

In the toilet 200 with this structure, the user can control a controller (not shown) or set the blower fan 224 and the electric heater 225 to operate at regular intervals by using a timer (not shown).

At this time, as the blowing fan 224 and the electric heater 225 are turned on and off at regular intervals, the air heated by the electric heater 225 is sent to the hot air pipe 226 by the blowing fan 224. is heated as a whole.

The heated air inside the hot air pipe 226 is quickly discharged upward from the exhaust pipe 230 through the air outlet 226b.

As the hot air pipe 226 is heated and light is transmitted into the lower body 220 through the light-transmitting member, the overall internal temperature of the lower body 220 rises rapidly, and the excrement accumulated inside the lower body 220 is removed. It can dry quickly.

The air flowing into the first vertical duct 231 from the lower body 220 quickly passes through the venturi-type connector 232 with a smaller diameter and rotates the fan of the fan unit 237, thereby creating a fan unit ( Electrical energy can be produced by a generator 238 connected to 237).

The electricity produced by the generator 238 is stored by a capacitor and can be used as a power source to operate the blower fan 224 and the electric heater 225.

A solar sensor is installed in the heating jacket 234, and on days with little sunlight such as cloudy or rainy days, electricity produced by the generator 238 is supplied to the blower fan 224 or the electric heater 225. By doing this, forced air circulation can be induced.

In the toilet 200 of this embodiment, an additional air heating means is installed in the lower body 220 in addition to the exhaust pipe 230, so that odors in the lower body 220 can be more effectively discharged through the exhaust pipe 230, While actively drying and decomposing manure, the electricity produced by the generator 238 can be supplied to the blower fan 224 or the electric heater 225, thereby inducing forced air circulation on days with little sunlight. .
