In order to achieve the above objects, the present invention is implemented through the following technical solutions.

A public restroom, as shown in Figures 1 and 2, includes an outer wall 1, a restroom 3 arranged in the outer wall, a suspended ceiling and a roof. The outer wall 1 has opposite gates 2 for people to enter and exit. There is a certain width between the exterior wall 1 and the bathroom 3, forming an aisle 8. There is a sloped roof above the aisle 8, and solar panels 16 are attached to the slopes of the roof. The solar panels convert the collected solar energy into electrical energy for use in generating electricity for the water pump.

As shown in Figure 3, the bathroom 3 is composed of multiple toilet rooms. There is a door 5 on the toilet room and a squat toilet 7 inside. The inner side of the toilet room and the inner side of the ceiling 20 (the side closest to the outer wall 1 is The outer side 19 (the side away from the outer wall 1 is the inner side 20) is spliced at the center to form a side-closed, longitudinal hollow cylinder as a synthetic channel 4. The synthetic channel 4 is a channel for ventilation and rainwater collection.

As shown in Figure 4, the suspended ceiling consists of a water storage tank 6 and a ventilation channel 14 arranged above the bathroom single room. The water storage tank 6 and the ventilation channel 14 can be arranged spaced apart from each other. There are two vents at opposite positions on the inner and outer sides of the ventilation duct. The inner vent 15 is an exhaust port and is connected to the synthetic channel 4. The outer vent 18 is an air inlet. Preferably, the air inlet is larger than the exhaust port. big. Preferably, the ventilation duct is located directly above the middle of the two bathroom single rooms in order to improve efficiency and serve the two bathroom single rooms at the same time. The water storage tank 6 can be made of a transparent material. While transmitting light, heat is absorbed by the water, thereby achieving the effect of transmitting light but not transmitting heat. Since the upper and lower sides of the water storage tank are unobstructed, external light can be ensured to enter each bathroom unit through the water storage tank, thereby saving energy. The upper surface of the suspended ceiling forms part of the roof and is horizontal in shape.

In one embodiment, as shown in Figure 4, the outer wall 1 is cylindrical, and the cross-sections of the bathroom single room, water storage tank, and ventilation duct are trapezoidal, and are placed close to each other to form a ring shape.

As shown in Figure 5, a shutter 9 is provided at the top of the synthetic channel 4, and a filtered water tank 10 is provided at the bottom. A water pump 11 and a water distributor 12 are connected below the filtered water tank 10. The water distributor is connected to a water supply pipe 13. The water supply pipe 13 is connected to the water storage tank 6 above each bathroom unit. Synthetic channel 4 has rainwater collection function. Rainwater flows through the blinds 9 through the synthetic channel 4 and is collected in the filtered water tank 10 for filtration and storage. The water in the water tank 10 is driven into the upper water pipe 13 through the water pump 11 and the water distributor 12. The water flows through the upper water pipe 13 and enters the top of each toilet room. stored in the water storage tank 6. The water supply pipe 13 can be made of transparent material, and the cross section can be rectangular. The transparent material of the water supply pipe 13 is exposed to the outside environment, allowing outside light to shine in, and functions as a window. At the same time, when the sunlight shines on the water flow in the water supply pipe, the water will be preheated, that is, the water will take away the heat generated by the sunlight. , prevent heat from entering the room, and have the effect of transmitting light and not transmitting heat. Through the above structure, rainwater can be fully utilized and water resources can be saved.

Preferably, as shown in Figure 1, the water supply pipes 13 can be equidistantly inserted into the exterior wall and arranged alternately with the exterior wall 1 to be exposed to the external environment and symmetrical to the central axis of the public toilet.

As shown in Figure 6, the public restroom of the present invention also includes a plurality of ventilation ducts with one end connected to the bathroom aisle 8. The ventilation ducts are buried underground and are called underground pipes 17, and the other end is away from the public restroom. Exposed to the ground, for example, it can be installed under a park bench. Because the underground temperature is constant and lower than the outside temperature in summer, the outside hot air will be gradually cooled after flowing into the tunnel. In this way, the air temperature entering the bathroom and corridor is lower than the outdoor temperature, which plays a natural cooling role and saves energy. When the rooftop solar panel receives solar light, it will generate a large amount of radiant heat, causing the air temperature above bathroom 3 to be high and the pressure to be reduced. Therefore, the cold air below will rise and push the hot air above into the ventilation duct, thereby causing the hot air to flow along the ventilation channel. Channels, synthetic channels, and blinds are discharged to the outside, and the new cold air above will be gradually heated and turned into hot air with less density, and then displaced out. In this way, the indoor air is renewed. This structure guides indoor air and prevents hot air from intruding into the toilet area where people are. Preferably, the ventilation duct is tapered, and the gradual reduction of the cross-sectional area can speed up the flow rate of hot air and achieve better ventilation. A switch is provided at the air outlet of the underground pipe 17, and the air outlet of the underground pipe 17 can be closed in winter, thereby slowing down the air flow and maintaining the indoor temperature.

The invention has a novel structure, which not only keeps the indoor air of the public toilet suitable, but also can make full use of natural conditions, such as rainwater, underground cooling, etc., thereby reducing energy consumption, and is also beautiful and elegant.

Finally, it should be noted that the above embodiments are only used to describe the technical solutions of the present invention and do not limit the technical methods. The present invention can be extended to other modifications, changes, applications and embodiments in application, and therefore it is considered that all such Modifications, changes, applications, and embodiments are within the spirit and scope of the present invention.
