[0001] The present application relates to the technical field of toilets, and in particular to a control method, device, electronic device, and computer storage medium for an ecological toilet. Background Art

[0002] Common outdoor toilets generally solve excrement by flushing water. In areas with extreme weather environments such as cold, drought and water shortage, the application of common outdoor toilets is very limited. In order to solve the application limitations of common outdoor toilets, an ecological toilet is proposed.

[0003] Ecological toilets are a form of outdoor toilets. In order to treat the excrement inside the toilet in a pollution-free manner, microbial decomposition technology can be used to decompose the excrement inside the toilet, or the excrement can be packaged and then manually transported for centralized treatment.

[0004] Manual transportation and centralized treatment will consume a lot of human resources and economic resources. In areas with extreme weather environments, the use of microbial decomposition technology to decompose and treat excrement inside toilets has the problem of low operating efficiency.

[0011] It further includes: when it is determined that the temperature inside the ecological toilet is lower than the second threshold and it is determined that the activity state of one or more moving objects in the ecological toilet has changed, determining the new activity state of the moving object and the new area to which the moving object belongs; determining the temperature requirement of the new area according to the pre-set correspondence between the activity state and the temperature requirement; and determining the heat dissipation power of the new area according to the temperature requirement.

[0012] The activity state includes leaving; the new area includes outside the ecological toilet; determining the temperature requirement of the new area according to the pre-set correspondence between the activity state and the temperature requirement includes: when it is determined that the activity state is leaving the ecological toilet and the time outside the ecological toilet is greater than the set duration, determining to reduce the temperature requirement of the ecological toilet according to the pre-set correspondence between the activity state and the temperature requirement; and the activity state includes squatting; the new area includes within the set range of the collection and treatment device; determining the temperature requirement of the new area according to the pre-set correspondence between the activity state and the temperature requirement includes: when it is determined that the activity state is squatting and within the set range of the collection and treatment device, determining to increase the temperature requirement of the ecological toilet according to the pre-set correspondence between the activity state and the temperature requirement.

[0016] A computer storage medium stores a computer program, wherein the computer program is designed to implement a control method for an ecological toilet when running.

[0017] The control method of the ecological toilet proposed in this application determines the heat dissipation power required to consume the excrement based on the density of the excrement and the physical properties of the ecological toilet when the presence of excrement is determined. Based on the heat dissipation power, the excrement is heated and microorganisms are introduced to decompose the excrement, thereby ensuring the normal decomposition of excrement inside the toilet by microorganisms, improving the environmental cleanliness around the toilet in extreme environments, and saving human and economic resources.

[0033] Below, this application is described in detail.

[0034] Toilets are a cornerstone of social civilization. They not only impact public health, social equity, and the well-being of vulnerable groups, but also serve as a crucial link between people and the natural environment. Improperly treated excrement not only pollutes land and water resources but also increases the risk of disease transmission. Therefore, toilet reform is urgent.

[0035] In the related art, in order to carry out pollution-free treatment of excrement inside the toilet, microbial decomposition technology can be used to decompose and treat the excrement inside the toilet.

[0036] However, in cold northern regions, where outdoor temperatures are low, outdoor toilets, especially dry toilets, are prone to freezing, which can hinder the microbial decomposition of excreta. In arid regions lacking water sources, despite high temperatures, the lack of water allows excreta to leak and easily breed mosquitoes. Over time, this can render toilets unusable, further impacting the ecological environment.

[0037] Although in existing toilet renovations, there has been a practice of burying excrement storage tanks deep below the permafrost line to avoid freezing, this approach requires a large amount of excavation and construction, and the wall thickness of the excrement storage tanks also needs to be thickened, which also brings about the problem of high toilet renovation costs. In addition, since the excrement storage tanks are located deep in the soil, the pressure is relatively high, so the risk of soil pollution is also increased, and the risk of groundwater pollution is also increased accordingly.

[0038] Based on this, Figure 1As shown in the figure, the present application provides an ecological toilet 01, which includes a toilet compartment 1, a collection and treatment device 2, a heat conduction channel a, a heat collecting plate 3, and a first fan 4. The toilet compartment 1 has a toilet entrance. The collection and treatment device 2 has a receiving space b communicating with the toilet entrance, and the receiving space b is used to collect excrement discharged from the toilet entrance and perform microbial treatment. The receiving space b may include a first storage chamber b1 and a second storage chamber b2. In some examples, such as Figure 1 As shown in the figure, an opening communicating with the inside of the toilet compartment 1 is formed on the toilet compartment 1, and a door body 11 is connected to the opening. The door body 11 is used to open or close the opening to meet the toilet needs of users. The door body 11 can be made of any material. For example, it can be made of metal, plastic, or can also be made of stone, wood or rattan materials, and no specific limitation is made in the present application.

[0039] In some examples, such as Figure 1 The bottom of the toilet compartment 1 is further connected with a bearing platform 12, and the bearing platform 12 plays a bearing role.

[0040] Among them, the bearing platform 12 can be made of materials such as cement board and plastic board, and no specific limitation is made in the present application. Specifically, the bearing platform 12 can also be in a stepped shape.

[0041] In some examples, the heat conduction channel a can be a part of the collection and treatment device 2. Or, the heat conduction channel a can also be a separate pipe, which is in contact with the collection and treatment device 2. As long as the heat in the hot air in the heat conduction channel a can be conducted to the collection and treatment device 2, and then conducted to the excrement in the receiving space b.

[0042] In some examples, such as Figure 1 As shown in the figure, the ecological toilet 01 further includes a toilet 13 or a squatting pan arranged inside the toilet compartment 1, and the toilet entrance is formed on the toilet 13 or the squatting pan. The setting of the toilet 13 or the squatting pan can improve the toilet experience.

[0043] In some examples, the first fan 4 can be arranged at the inlet end of the air flow channel c, so that the air outside the toilet compartment 1 can be better sucked into the air flow channel c. Of course, the first fan 4 can also be arranged in the middle of the air flow channel c.

[0044] Among them, the first fan 4 can be an axial flow fan.

[0045] The setting methods of the collection and treatment device include at least one of the following:

[0046] Fully buried underground; half buried underground; set on the ground;

[0047] When the collection processor is set in a semi-buried and / or above-ground manner, the ecological toilet further includes a sealing plate for enclosing the collection processor; and / or the ecological toilet further includes steps for reducing the height to reach the collection processor.

[0048] With the above settings, people can carry out excretion activities in the toilet compartment 1, and discharge excrement into the receiving space b through the toilet inlet. Since the heat collecting plate 3 is arranged outside the toilet compartment 1, the heat collecting plate 3 can collect the heat of the sun, and then transfer it to the air in the air flow channel c formed between the heat collecting plate 3 and the outer wall surface of the toilet compartment 1. Since the inlet end of the air flow channel c is communicated with the outside of the toilet compartment 1, the outlet end of the air flow channel c is communicated with the inlet end of the heat conduction channel a, and the outlet end of the heat conduction channel a is communicated with the outside of the toilet compartment 1, under the action of the first fan 4, the air that has absorbed heat can flow on the air flow path formed by the air flow channel c and the heat conduction channel a. When the hot air passes through the heat conduction channel a, the heat in the hot air will be transferred to the receiving space b through the side wall of the heat conduction channel a and the side wall of the collection and treatment device 2, so as to heat the excrement in the receiving space b, so as to ensure that the microorganisms in the receiving space b are in a suitable temperature environment and decompose the excrement normally.

[0049] This heating method utilizes solar energy, a clean energy source, without the need to use electric energy. Therefore, it can reduce energy consumption, reduce usage costs, and is cleaner and more environmentally friendly. In addition, by using solar energy, the environmental temperature inside the ecological toilet can be maintained under extremely cold conditions. If it is connected to electric energy, the electric energy can be converted into heat energy, or the ecological toilet can be directly controlled by electric energy.

[0050] The air inside the toilet compartment 1 is usually worse than that outside the toilet compartment 1. Therefore, it is necessary to ventilate the toilet compartment 1 to ensure the freshness of the air inside the toilet compartment 1.

[0051] When there is no one inside the toilet compartment 1, at this time, the hot air in the heat conduction channel a will completely enter the exhaust channel d through the outlet end of the reversing valve to continuously heat the receiving space b.

[0052] As Figure 1 shown, the toilet compartment 1 also has a cleaning channel i communicated with the receiving space b. By setting the cleaning channel i, the cleaning personnel can clean the excrement in the receiving space b through the cleaning channel i.

[0053] Among them, when the receiving space b includes a first storage cavity b1 and a second storage cavity b2, the cleaning channel i is communicated with the first storage cavity b1.

[0054] In some embodiments, the heat conduction channel may contain a heat conduction medium. The heat conduction medium can completely or partially fill the heat conduction channel, and the ecological toilet is heated through the heat conduction medium. Since the heat conduction medium has a better heat transfer effect than air, the heat transfer effect can be improved better. The heat conduction medium can be hot oil or a two-phase medium.

[0055] Specifically, the two-phase medium can use low-viscosity silicone oil or ethylene glycol-water mixture (anti-freezing type), and with a magnetic pump circulation, it can better avoid solidification at low temperatures.

[0056] In some embodiments, an integrated plate heat exchanger can also be included to improve the heat exchange efficiency between the two-phase medium and the reaction area. Heat pipes are embedded in key parts to utilize phase change for rapid heat equalization.

[0057] The phase change heat storage base (PCM) can select paraffin (phase change temperature 0 - 5 °C) or salt hydrate materials, which are encapsulated in an aluminum honeycomb structure base.

[0058] In some embodiments, stratified heat storage can also be designed: the upper layer absorbs heat rapidly during the day, and the lower layer releases heat slowly at night to extend the heat preservation time. Combining with a graphene coating to enhance heat conduction and improve the heat storage / release rate.

[0059] In some embodiments, combined with the heat conduction channel, intelligent temperature control and system integration can be constructed. For example, an adaptive control algorithm is introduced to dynamically adjust the power of the heating belt based on a PID controller, and preheating is combined with weather forecasting. Internet of Things remote monitoring can also be introduced: temperature and power data are transmitted in real time through 5G / 4G / LoRa modules to support remote intervention.

[0060] In some embodiments, for waste heat recovery of exhaust gas: a heat exchanger can be installed in the exhaust pipe to preheat the cold air entering the system. The reaction cavity adopts a double-layer stainless steel sandwich vacuum structure to reduce heat loss.

[0061] In addition, a cover plate can be set at the cleaning channel i, and the cleaning channel i is closed or opened by using the cover plate, so that when cleaning is required, the cleaning channel i is opened, and when cleaning is not required, the cleaning channel i is closed.

[0062] As Figure 2 shown, the present application provides a control method for an ecological toilet, and the specific processing flow is as follows:

[0063] Step 21, determine whether there is excrement in the collection and treatment device. If the judgment result is yes, execute step 22. If the judgment result is no, end the processing.

[0064] In the technical solution proposed in this application, different sensors can be set in the ecological toilet, such as temperature sensors, humidity sensors, infrared sensors, human body sensors, smoke sensors, etc. These sensors can be set with different quantities and different types according to the environment where the ecological toilet is placed and the requirements for collecting data. In terms of power supply, two options of active and passive can be selected. Passive can be powered by solar energy, and active can choose electric power supply.

[0065] In specific implementation, the heat collection plate in the ecological toilet proposed in this application can generate electricity through photovoltaic power generation, can be connected to a large windmill, and can collect solar energy and convert the collected energy into electric energy and other ways. This can adapt to setting the ecological toilet proposed in this application in a power-free and arid environment.

[0066] The heat collection plate in this application can also be connected to a power supply, so as to adapt to the situation where power can be connected in a harsh environment. For example, in rural areas in the extreme north, electric energy is available, and the electric energy can provide kinetic energy for the ecological toilet through the heat collection plate.

[0067] In some embodiments, in low-temperature regions with a minimum temperature of -10 to 0 °C, the electric heating tape heating method can be adopted. The heat collection plate 3 is used to collect solar energy, and the solar energy powers the battery. When heating is required, electric energy is extracted to heat the heating wire, so as to ensure that the internal temperature reaches the reaction requirements.

[0068] In some embodiments, the heat collection plate can reserve an electrical interface and can supply power to the system when environmental conditions permit.

[0069] In some embodiments, design can also be carried out for extreme environment adaptability. For example, for the anti-freezing and self-maintenance mechanism, the pipe electric tracing tape + intelligent temperature control can be adopted, and the anti-freezing mode is automatically turned on when the temperature is lower than 2 °C.

[0070] In some embodiments, a self-cleaning function can be set for the heat collection plate, such as integrating a vibration motor or a hydrophobic coating to prevent snow / ice coverage.

[0071] In some embodiments, key components (such as pumps, controllers) adopt dual-machine hot standby, automatically switch when a failure occurs, and have quick-release pipeline interfaces, which are convenient for quickly replacing damaged modules.

[0072] In some embodiments, the heating device can be adapted to scenarios such as greenhouse soil heating and oil pipeline tracing, and the temperature threshold can be adjusted. It can also be expanded into a regional microgrid node to supply power to other devices.

[0073] In some embodiments, a vehicle-mounted device can also be developed for temporary heating in polar scientific research or disaster relief. In this way, using the ecological toilet proposed in this application can better protect the ecological environment.

[0074] In some embodiments of the eco-toilet system proposed in this application, pressure and leakage sensors in the media circulation system trigger an emergency shutdown in the event of an emergency. The electric heating system features overcurrent protection and ground fault detection, meeting IP67 protection standards. Aerospace-grade sealing materials are used to withstand temperature fluctuations of -40°C to 120°C. A self-diagnostic system regularly monitors component lifespan and provides early warning of replacements.

[0075] With the continuous development of technology, machine learning can predict energy consumption curves and dynamically adjust energy storage and consumption strategies. Adding carbon nanotubes or alumina nanoparticles to heat transfer media can increase thermal conductivity by over 20%. Laser charging or microwave power supply are being explored to achieve contactless emergency energy replenishment.

[0076] This solution can maintain a stable reaction temperature of 5-25°C in extreme environments of -30°C, improving overall energy efficiency by over 40%. It also offers adaptability and high reliability in multiple scenarios. The next step is to verify the design through digital twin simulations and conduct small-scale field tests to optimize parameters.

[0077] In the specific implementation, this application does not make specific limitations, as long as it can provide the energy required by the corresponding ecological toilet, the energy may include but is not limited to kinetic energy, electrical energy and thermal energy.

[0078] Step 22: When it is determined that there is excrement, the density of the excrement is determined.

[0079] In specific implementations, the ecological toilet proposed in this application has a collection and treatment device that can directly receive excrement, where microorganisms are placed. The collection and treatment device can also be connected to a storage space, allowing excrement to be directly discharged into the storage space, where microorganisms can be placed, thereby further concentrating the excrement. However, this application does not specifically limit the specific method for receiving excrement.

[0080] The microorganisms can be delivered in batches or all at once, and this application does not impose any specific restrictions. As long as the microorganisms can decompose excrement, the specific components they contain are not specifically limited in this application.

[0081] When it is detected that there is excrement in the collection and treatment device and / or the receiving space, the density of the excrement is determined, and based on the corresponding density, it can be detected whether the excrement is urine or feces, or whether the excrement is a mixture.

[0082] Step 23: Determine the heat dissipation power required to consume the excrement according to the density of the excrement and the physical properties of the eco-toilet.

[0083] According to the physical properties of the ecological toilet, determine the heat loss rate, subtract the heat radiation power of the ecological toilet from the heat loss rate to determine the net output rate of heat radiation, and determine the heat dissipation power for consuming the excrement according to the density of the excrement and the net output rate of heat radiation.

[0084] Excrement with different components can be processed through different treatment methods, and different treatment methods correspond to different heat dissipation powers. If the excrement is only urine, it can be directly evaporated and discharged by direct heating. If it is a mixture, the excrement can also be heated to evaporate the liquid and the remaining part is inoculated with microorganisms. If the excrement is only feces, then it can be directly heated to the temperature at which microorganisms act.

[0085] In specific implementation, before determining the heat dissipation power for consuming excrement according to the density of the excrement and the physical properties of the ecological toilet, it further includes: when it is determined that the temperature inside the ecological toilet is lower than the first threshold, obtain the temperature inside the ecological toilet; determine the heat dissipation power for consuming excrement according to the temperature inside the ecological toilet, the density of the excrement, and the physical properties of the ecological toilet.

[0086] In this implementation manner, when determining the heat dissipation power, the ambient temperature is considered at the same time. If the ambient temperature is high, the heat dissipation power can be appropriately reduced to save energy. If the ambient temperature is low, the heat dissipation power can be appropriately increased to provide heat higher than the temperature for decomposing excrement, so that the decomposition effect of excrement is better.

[0087] Take an example for elaboration. When determining the heat dissipation power required for excrement, if the ecological toilet is in an extremely cold environment, then the temperature inside the ecological toilet is surely lower than zero degrees. Excluding the influence of the perceived temperature brought by wind, when calculating the heat dissipation power, considering the temperature inside the ecological toilet, and further considering factors such as the temperature of the collection and treatment device for receiving excrement inside the ecological toilet, the material of the collection and treatment device, and the size of the collection and treatment device, the actual heat dissipation power should be greater than the heat dissipation power for directly heating the excrement. If the ecological toilet is in an extremely hot situation, then the temperature inside the ecological toilet is surely as high as the ambient temperature. When calculating the heat dissipation power, considering the temperature inside the ecological toilet, and further considering factors such as the temperature of the collection and treatment device for receiving excrement inside the ecological toilet, the material of the collection and treatment device, and the size of the collection and treatment device, the actual heat dissipation power should be less than the heat dissipation power for directly heating the excrement, that is, a little heating or even no heating can achieve the temperature for microorganism action and achieve the purpose of decomposing excrement.

[0088] In specific implementation, in the technical solution proposed in this application, solar heat:

[0089] Assume the maximum sunlight intensity is 900W / M 2 , direct sunlight, absorption rate 100%,

[0090] The total heat dissipation power is 900 * 1.17 * 0.78 = 821 W.

[0091] For example, if the temperature is very low and the excrement is urine, assuming half of 0.75 m 3 which is 0.375 m 3 and the urine temperature is 0 C ice, and all the heat is given to the urine to turn it into liquid, it takes 375 kg * 334 kJ / kg / 821 W * 1000 J / kJ / 3600 s / h = 42 h

[0092] Furthermore, assuming half of 0.75 m 3 which is 0.375 m 3 and the urine temperature is 0 C ice, and all the heat is given to the urine without considering heat dissipation at all, and when the heating element power is 60 W, the working time is: 375 kg * 334 kJ / kg / 60 W * 1000 J / kJ / 3600 s / h = 580 h

[0093] Considering environmental impacts, such as the soil:

[0094] The heat dissipation power = the heat dissipated externally – the heat conduction of the urine

[0095] Among them, the thermal conductivity of dry soil is usually between 0.25 - 0.35 W / (m·K); the thermal conductivity of HDPE is about 0.4 - 0.5 W / (m·K); assuming the soil thickness is 0.5 m, the urine temperature is 10 C and the air temperature is -10 C and the area of the outer shell (collection and treatment device or others) is about 2 m 2

[0096] The heat dissipation power QL = 2 m 2 * 20 C * 0.35 W / (m·K) / 0.5 m = 28 W

[0097] The heat dissipated externally – the heat carried away by the cold air

[0098] To maintain the reaction, cold air needs to continuously enter. Assuming the cold air temperature is -10 C and the air inlet flow rate is 1 m / s, the aperture is 0.1 m, the air volume flow rate is 0.1 * 0.1 * pi / 4 * 1 m 3 / S, and the mass flow rate is 0.010 kg / S;

[0099] The cold air flows over the feces surface, and the heat exchange amount is calculated according to natural convection heat transfer. The feces are equivalent to a 1-square-meter flat plate, the feces temperature is 10 C and the average temperature difference is 16 C

[0100] According to Newton's law of cooling, the heat dissipation is ~80W

[0101] When the air takes away the heat, the temperature change is 80 / 1005 / 0.01 = 8 C , and the outlet temperature is -2 C

[0102] If not in accordance with natural convection and when the air flow velocity is a bit large, 5m / s

[0103] Ignoring other heat dissipations, when the outdoor temperature is -10 C , the temperatures of urine and feces are both 0 degrees, and the total heat dissipation power is 108W. When the outdoor temperature further drops to -20 C , the heat dissipation power is 162W. When the wind is a bit strong, the heat dissipation power can be as high as 500W.

[0104] The heat release of aerobic decomposition of feces

[0105] Assumption: The heat release of aerobic decomposition of feces is 15kJ / g. If 1kg of feces is newly produced in one day and the decomposition amount in one day is also 15000kJ

[0106] The heat release is 15000000 / 24 / 3600 = 173W

[0107] Actually, the aerobic decomposition time is about 20 days, and the heat dissipation power is 173 / 20 = 8.6W

[0108] After 20 days of accumulated feces form a cycle, there are 20kg of feces reacting, and the heat dissipation power reaches 173W

[0109] Based on parameters such as the heat dissipation power, the heat taken away by the external air, and the heat generated by the feces itself, a calculation model is established. Through the operation of this model, the relationship between the heat dissipation and the heat generation can be determined, and then the thermal equilibrium state can be achieved. At the same time, this model also considers key factors such as heat dissipation through soil contact, thermal resistance calculation, and the influence of the air intake on the heat dissipation. To improve the decomposition efficiency, it is recommended to reduce the surface area of contact between the cold air and the excrement. In addition, this study also explores the possibility of combining solar thermal technology and solar power generation technology, and analyzes the challenges in terms of cost, complexity, and reliability that these technologies may bring.

[0110] Step 24, after decomposing the excrement, when it is determined that the temperature inside the ecological toilet is lower than the first threshold and / or the brightness outside the ecological toilet is lower than the first set value, keep the temperature of the collection and treatment device in the ecological toilet at the set temperature value.

[0111] In this step, to ensure that the temperature inside the ecological toilet is sufficient to prevent excrement from freezing, after decomposing the excrement, if it is detected that the temperature inside the ecological toilet is too low, the heat dissipation power can be adjusted to maintain the temperature of the collection and treatment device within a preset temperature range.

[0112] In this step, to ensure that the temperature inside the ecological toilet is sufficient to prevent excrement from freezing, after decomposing the excrement, if both the temperature and light in the ecological toilet are very low, such as in polar night areas, the heat dissipation power can be adjusted to maintain the temperature of the collection and treatment device within a preset temperature range.

[0113] In this application, the physical properties of the ecological toilet include at least one of the following:

[0114] The size of the ecological toilet. When calculating the heat dissipation power, the size of the ecological toilet is considered. If the ecological toilet has a large space, a larger heat dissipation power is required during heating.

[0115] The height of the collection and treatment device in the ecological toilet from the ground;

[0116] The size of the collection and treatment device in the ecological toilet;

[0117] The material of the collection and treatment device in the ecological toilet;

[0118] The shape of the collection and treatment device in the ecological toilet.

[0119] In specific implementation, if a containment space is further connected in the collection and treatment device, the physical properties such as the size, material, and shape of the containment space can be further considered when calculating the heat dissipation power, and these physical properties can all affect the level of heat dissipation power.

[0120] In a preferred implementation, in the technical solution proposed in this application, the heat collection plate stores thermal energy by collecting solar energy, and realizes the energy supply of the ecological toilet through thermal energy conversion. Among them, the system heat calculation includes the heat absorption calculation of the solar heat pipe, the self-heating calculation, and the heat calculation required for the system to maintain a specified temperature.

[0121] In specific implementation, the heat absorption calculation of the solar heat pipe can comprehensively consider multiple factors, including solar radiation, heat loss of the heat pipe, net output power of the heat pipe, and environmental conditions, etc. Specifically, the main steps and relevant formulas of the heat absorption calculation can be referred to:

[0122] Heat absorption calculation of the solar heat pipe:

[0123] The heat absorption of the solar heat pipe mainly comes from solar radiation. The absorption power of the heat pipe can be calculated by the following formula:

[0124] Qabs = α·I·A

[0125] In the above formula, Qabs is the absorbed solar radiation power (unit: W), α is the absorptivity of the heat pipe surface, usually between 0.9 and 0.96, I is the solar radiation intensity (unit: W / m 2 ), which is about 1000 W / m under sunny conditions 2 , A is the heat absorption area of the heat pipe (unit: m 2 ), usually the projected area of the outer surface of the heat pipe.

[0126] Heat loss of the heat pipe

[0127] During the operation of the heat pipe, heat will be dissipated to the environment through radiation, convection, conduction, etc. The heat loss can be estimated by the following formula:

[0128] Qloss = ULT·A·(Tabs - Tenv)

[0129] Where, in the above formula, Qloss is the heat loss power (unit: W), ULT is the average heat loss coefficient (unit: W / (m 2 ·℃)), which can be determined by experiments, Tabs is the surface temperature of the heat pipe (unit: ℃), and Tenv is the ambient temperature (unit: ℃).

[0130] Net output power of the heat pipe (Qnet)

[0131] The net output power of the heat pipe is the absorbed solar radiation power minus the heat loss:

[0132] Qnet = Qabs - Qloss

[0133] In specific implementation, the self-heating calculation involves multiple steps, which can but are not limited to including calculating the volume of the device, determining the self-heating amount, and converting the self-heating amount into the emission power. First, the device volume is calculated based on the external dimensions of the device container, and its unit is liters. Secondly, the determination of the self-heating amount is calculated based on the heat absorbed by the contained substance per 1℃ increase, and then the total heat dissipated by the entire volume of the substance under specific conditions is obtained, and the unit is kcal. According to the conversion of heat into power: 700 kw = 600,000 kcal, and the conversion can be carried out according to the proportion.

[0134] Calculation of the heat required for the system to maintain the specified temperature

[0135] In specific implementation, the heat required for the material to maintain the temperature is calculated according to the effective volume of the device, which is the heat required per 1℃ increase multiplied by the volume (liters), and the unit is kcal; the heat is converted into power according to the conversion. If the heat pipe power + the self-heating power > the required heat, the system can maintain the temperature, otherwise the temperature will gradually decrease.

[0136] Optionally, in the technical solution proposed in this embodiment, when it is detected that the temperature inside the ecological toilet drops below the second threshold and it is confirmed that the activity status of one or more moving objects inside the ecological toilet has changed, the current activity status of the moving objects and the new areas to which they belong will be re-evaluated. Based on the pre-set correspondence between the activity status and the temperature requirements, the temperature standard required for the new area will be determined; furthermore, based on these temperature requirements, the heat dissipation power required for the new area will be calculated.

[0137] The activity status includes any one of leaving, standing up, and walking; the new areas include outside the ecological toilet and each divided area inside the ecological toilet, such as the area far from the toilet area, the area close to the toilet area, the area close to the door, the area close to the corner, etc. These area divisions have different temperature requirements, and the specific division is not specifically limited.

[0138] Preferably, when it is determined that the activity status is leaving the ecological toilet and the time outside the ecological toilet is greater than the set duration, according to the pre-set correspondence between the activity status and the temperature requirements, the temperature requirement for reducing the ecological toilet is determined.

[0139] Preferably, the activity status includes squatting; the new area includes within the set range of the collection and treatment device; when it is determined that the activity status is squatting and within the set range of the collection and treatment device, according to the pre-set correspondence between the activity status and the temperature requirements, the temperature requirement for increasing the ecological toilet is determined. In this scenario, it is applicable to ensure that the environmental temperature of the ecological toilet is at a suitable temperature when the user is using the toilet.

[0140] In specific implementation, the heat required to maintain the temperature of the new area can be determined according to the temperature requirement, and the heat is converted into the heat dissipation power, which is used as the heat dissipation power of the new area after conversion.

[0141] The internal area of the ecological toilet is divided into interconnected sub-areas A1, A2,..., An. Define the thermodynamic properties of each area:

[0142] Heat capacity Ci (J / ℃)

[0143] Thermal resistance Rij (℃ / W, the thermal resistance between area i and j)
