[0028] The present invention provides a solar hot air aerated dry toilet, which utilizes a solar air collector to heat the air through solar energy supply, thereby heating the air in the toilet room and raising the temperature in the toilet room; at the same time, the air in the toilet room is ventilated to accelerate the evaporation process of urine, shorten the urine hydrolysis time, reduce the odor generated by urine hydrolysis, and reduce the odor effect of the septic tank from the feces entrance of the toilet, thereby achieving low energy consumption, high efficiency and stable operation.

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1 Please refer to Figures 1 to 4 The present embodiment provides a solar hot air aeration dry toilet, comprising a toilet chamber 1, a feces and urine storage tank 2 and a feces and urine collection toilet 3; Solar air collectors are provided on the top and walls of the toilet room 1; The feces and urine storage tank 2 is arranged at the bottom of the toilet chamber 1; The urine-feces collecting toilet 3 is arranged on the bottom plate of the toilet chamber 1, and the urine-feces are discharged into the urine-feces storage tank 3 through the urine-feces collecting toilet 3; The solar air collector can heat the air and introduce it into the toilet room 1 and the feces and urine storage tank 2.

[0031] Specifically, the toilet room 1 is a square box, the space of which is sufficient for people to use the toilet. The toilet room 1 includes three insulated walls and a door, and the walls and the door can be made of insulation boards.

[0032] The solar air collector includes a shell 4, which is arranged on the top of the toilet room 1 as the roof of the toilet room 1. The shell 4 is provided with an air heating pipe chamber and an air baffle chamber. The air heating pipe chamber is provided with an air heating pipe 5. The air heating pipe 5 can be made of a thin-walled copper pipe, and its surface is sprayed with solar light-absorbing paint, which can better absorb solar energy and heat the air flowing therein. The air heating pipe 5 is coiled in a serpentine shape in the air heating pipe chamber, which lengthens the length of the air heating pipe 5 and allows the air inside to obtain more heat.

[0033] The air inlet end of the air heating pipe 5 extends out of the housing 4 and communicates with the external environment. The air inlet end of the air heating pipe 5 is provided with an air inlet duct fan 6. The air outlet end of the air heating pipe 5 extends into the air baffle chamber; the air baffle chamber is connected with the toilet room through the toilet room air inlet pipe 7. During operation, the external air is introduced through the air inlet duct fan 6, and the air is rapidly heat-exchanged through the serpentine thin-walled air heating pipe 5, so that the air in the pipe is continuously heated up; the heated air then passes through the air baffle chamber, and the baffle delays the passing time of the heated air, so that the air obtains more heat, and finally enters the toilet room through the toilet room air inlet pipe 7, so that the air in the toilet room is heated up, and the temperature in the toilet room is increased.

[0034] A plurality of interlaced baffles 8 are arranged in the air baffle chamber. The interlaced structure can delay the time for air to pass through the air baffle chamber and increase the temperature of the air therein.

[0035] In this embodiment, the air deflection chamber is provided with an air outlet, which is connected to a wall duct 9 arranged in the wall. The wall duct 9 is also made of a thin-walled copper tube and is arranged in a serpentine coil in three walls, thereby lengthening the flow path of the hot air, which is equivalent to increasing the heating area and can better achieve the effect of heat preservation.

[0036] The wall pipe 9 is provided with an air supply pipe fan 10, and the air outlet of the wall pipe 9 extends out from the bottom of the wall and is connected to the aeration main pipe 17, and the aeration main pipe 17 is connected to the aeration branch pipe 11, and the aeration branch pipe 11 extends into the feces and urine storage box 2. When the air supply pipe fan 10 is started, the hot air in the air baffle chamber can be introduced into the wall pipe 9, and the wall is heated through the wall pipe 9 to achieve a better insulation function. The hot air is then blown dry by the aeration main pipe 17 and the aeration branch pipe 11 to dry the feces and urine in the feces and urine storage box 2, which can accelerate the urine evaporation process, shorten the urine hydrolysis time, reduce the odor generated by urine hydrolysis, and reduce the odor effect of the septic tank from the toilet to the feces mouth, thereby achieving low energy consumption, high efficiency and stable operation. Under light conditions during the day, the wall pipe 9 in the wall can be ventilated to heat the toilet room 1. Under lightless conditions at night, air is a poor conductor of temperature, which can achieve toilet room insulation and delay the cooling rate of the toilet room.

[0037] In this embodiment, a sieve plate 12 is provided in the feces and urine storage box 2, the upper part of the sieve plate 12 is a feces storage box, and the lower part of the sieve plate 12 is a urine storage box; the sieve plate 12 is provided with sieve holes, so that urine can enter the urine storage box through the sieve holes. A cleaning door is provided at the rear side of the feces and urine storage box 2, and feces inside can be cleaned after the cleaning door is opened.

[0038] In this embodiment, the aeration branch pipe 11 includes a first aeration branch pipe 111 and a second aeration branch pipe 112. The first aeration branch pipe 111 and the second aeration branch pipe 112 extend into the feces storage tank and the urine storage tank respectively.

[0039] Specifically, the first aeration branch pipe 111 and the second aeration branch pipe 112 are divided into upper and lower sides, and each layer has a plurality of aeration branch pipes 11, which extend from the outside of the feces and urine storage box 2 into the feces storage box and the urine storage box, respectively, thereby improving the drying effect.

[0040] In this embodiment, a feces discharge port and a urine discharge port are provided in the feces-urine-dividing toilet 3. The feces discharge port 301 and the urine discharge port 302 are respectively located at two ends of the feces-urine-dividing toilet, which can avoid feces blocking the urine discharge port 302 as much as possible.

[0041] A urinary catheter 13 is connected between the urine drainage port 302 and the urine storage box, so that urine can be more directly introduced into the urine storage box.

[0042] In this embodiment, the top of the feces and urine storage box 2 is provided with an exhaust pipe 14 of the feces and urine storage box 2. Through the exhaust pipe 14, the feces and urine storage box 2 can be better discharged, and the peculiar smell in the toilet room 1 can be reduced.

[0043] Specifically, the dry toilet continuously delivers the hot air collected by the solar air collector to the first aeration branch pipe 111 and the second aeration branch pipe 112 through the aeration main pipe 17, and the first aeration branch pipe and the second aeration branch pipe are provided with aeration holes. The feces and sewage in the feces and sewage storage box are blown by the hot air to achieve rapid drying. The urine in the urine storage box is continuously aerated to achieve rapid evaporation to achieve volume reduction treatment, and the gas generated by aeration finally enters the outdoor space through the exhaust pipe 14.

[0044] In this embodiment, the shell 4 of the solar air collector is a square box, and the top of the shell 3 is a transparent plate, specifically a glass plate. Sunlight can directly shine on the surface of the air heating tube 5 through the glass plate, which is beneficial for the air heating tube 5 to absorb solar energy.

[0045] The outer side of the shell 2 is connected to an arc-shaped concentrator plate 15 through a first bracket, and the inner side of the arc-shaped concentrator plate 15 can be sprayed with reflective material. The outer side of the shell 2 is connected to a reflector 16 through a second bracket. The focus of the arc-shaped concentrator plate 15 is located on the reflector 16. The sunlight reflected by the arc-shaped concentrator plate 15 will converge on the reflector 16, and then the reflector 16 will reflect the light energy gathered by the arc-shaped concentrator plate 15 to the air heating tube 5, further heating the air in the air heating tube 5. Specifically, during installation, the angles of the arc-shaped concentrator plate 15 and the strip-shaped reflector 16 are adjusted to maximize the light collected by the arc-shaped concentrator plate 15, and the strip-shaped reflector 16 will reflect the gathered light to the serpentine air heating tube 5 in the shell 4, thereby enhancing the air heat collection effect.

[0046] In this embodiment, the air intake duct fan 6 and the air supply duct fan 10 can be connected to a solar panel (not shown), which is installed on the outside of the dry toilet. The solar panel generates electricity from solar energy to drive the operation of the two duct fans. The control switches of the air intake duct fan 6 and the air supply duct fan 10 can be set in the toilet room 1 to facilitate user control and use.

[0047] The solar hot air aerated dry toilet of this embodiment has two working modes when in use. One is to turn on the air intake duct fan 6 when using the toilet, introduce air, and after being heated by the solar air collector, enter the toilet room 1 through the toilet room air intake pipe 7, heat and ventilate the air in the toilet room 1, and enter the feces and urine storage box 2 below the toilet room 1 through the feces and urine collection toilet 3; the other is to turn on the air supply duct fan 10 when no one is using the toilet, and introduce the hot air inside the air collector into the wall duct 9 to achieve heating and heat preservation of the toilet room 1. Finally, the hot air dries the feces and urine in the feces and urine storage box 2 through the wall duct 9 in the insulation wall, the aeration main pipe 17 and the aeration branch pipe 11, and then discharges through the exhaust pipe 14. The dry toilet of this embodiment can heat the air in the toilet room, accelerate the evaporation process of urine, shorten the urine hydrolysis time, reduce the odor generated by urine hydrolysis, and reduce the odor effect of the septic tank from the toilet entrance.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
