Description

Technical Field

[0001] This invention relates to the field of indoor sterilization technology, and more specifically to a circulating sterilization method. Background Technology

[0002] With advancements in architectural structures and greening of indoor spaces, self-sterilization measures for indoor environments have become a hot topic. How to achieve self-sterilization and disinfection in indoor spaces has become an interdisciplinary field encompassing architecture, medicine, environment, and industrial design. Steam sterilization instruments for indoor sterilization have significant development potential.

[0003] Various fumigation devices that generate steam for users have appeared on the market. Existing fumigation devices generally involve adding water to a boiler, heating it to produce steam, and then outputting the steam through a delivery pipe connected to the boiler. Some existing technologies also incorporate sterilization functions into the humidifier.

[0004] For example, Chinese patent application number 201320493531.X, published on March 26, 2014, discloses a power-adjustable antiviral fumigation device, including an air outlet device and a steam generator. The air outlet device draws in air through an air inlet structure, generates wind, and blows it out from the air outlet structure. The steam generator is connected to a steam chamber. The steam generated by the steam generator, containing bactericidal molecules, is blown out from the air outlet structure in the direction of the airflow, which can quickly fill the room and sterilize the space, providing users with an environment that can resist viruses. A temperature sensor is installed in the steam chamber, and a temperature control chip is installed in the casing. The temperature control chip is electrically connected to the working circuit of the heating device. High-power heating boils water to generate steam. After the temperature sensor detects the steam temperature signal, it sends it to the temperature control chip. The temperature control chip processes the received temperature signal and outputs a power control signal to the working circuit of the heating device, so that the heating power of the heating device is reduced, realizing automatic adjustment of the heating power before and after steam output, reducing power consumption.

[0005] However, the steam sterilizers described in this application are all mobile devices. For some sterilizers with low emission power, the emitted steam can only stay near the sterilizer. Therefore, only mobile devices can meet the sterilization needs of different places in the room. This sterilization method is very inconvenient, and it is also difficult to discharge steam to higher places in the room, resulting in insufficient sterilization and reduced sterilization effect. Summary of the Invention

[0006] This invention provides a circulating sterilization method, which allows steam to circulate indoors, thereby achieving energy savings while maintaining a good sterilization effect.

[0007] To achieve the above objectives, the technical solution of the present invention is: a circulating sterilization method, wherein the steam sterilization method is implemented through a steam circulation system, the steam circulation system including a steam emission mechanism, a drying adsorption layer, and a steam condensation mechanism, the steam emission mechanism being located at the top of the building, the steam condensation mechanism being located at the bottom of the building exterior, and an exhaust assembly connected to the steam condensation mechanism being provided inside the building, with a drying adsorption layer laid on the walls inside the building; the steam condensation mechanism is connected to the steam emission mechanism via a liquid pipe; the steam emission mechanism includes a shell, a steam tank, a first heating component, and a second heating component, the shell being located at the top of the building, the air inlet of the shell being located outside the building, an I-shaped partition being provided at the center inside the shell, the air outlet of the shell being located inside the building, a steam tank being provided outside the building, the steam tank having an opening, the opening being connected to the air inlet of the shell via an air inlet pipe, and a first heating component being provided inside the steam tank; a steam channel connecting the air inlet and air outlet of the shell is provided inside the shell, and a second heating component is provided on the steam channel, the liquid pipe being connected to the steam tank; the specific steps include:

[0008] (1) The steam exhaust mechanism heats the water and exhausts steam into the building interior. Specifically, it includes steps (11)-(13).

[0009] (11) The first heating component heats the water in the steam tank to generate steam.

[0010] (12) Steam flows to the shell through the air inlet pipe.

[0011] (13) When the steam flows into the steam channel, the second heating component heats the steam a second time.

[0012] (14) The steam that has been heated a second time is discharged into the building interior through the outlet of the shell.

[0013] (2) Steam flows inside the building.

[0014] (3) When steam comes into contact with the wall, the dry adsorption layer adsorbs the steam.

[0015] (4) The exhaust system is activated to extract the air from the room.

[0016] (5) When the steam flows in the direction of the exhaust assembly, the exhaust assembly draws the steam to the steam condensation mechanism.

[0017] (51) The steam condensation mechanism condenses the steam into water to achieve recycling.

[0018] (6) The steam condensation mechanism delivers water to the steam discharge mechanism.

[0019] The above setup utilizes a steam exhaust system to heat water, generate steam, and discharge it into the room for sterilization. An exhaust system draws the steam out of the room, creating a consistent flow for better sterilization. A steam condensation system condenses the steam back into water, recycling it and saving energy. The system first heats the water in the steam tank with a first heating element, then further heats the steam with a second heating element, ensuring more even and reliable heating and improving steam generation efficiency. Allowing the steam to circulate within the building before activating the exhaust system ensures complete steam circulation, resulting in effective indoor steam sterilization.

[0020] Furthermore, a pumping assembly is provided inside the liquid pipeline, and step (6) specifically includes water being transported to the steam discharge mechanism through the pumping assembly.

[0021] Furthermore, the I-shaped partition includes a main partition, a top partition disposed at the top of the main partition, and a bottom partition disposed at the bottom of the main partition. The steam passage forms a first steam passage and a second steam passage through the I-shaped partition. The first steam passage and the second steam passage are respectively located on both sides of the main partition. A second heating component is provided on both sides of the main partition.

[0022] The above configuration, by setting up an I-shaped baffle, allows the steam entering the steam channel to flow in two separate paths, thereby enabling the second heating component to heat the steam more thoroughly.

[0023] Furthermore, step (1) also includes:

[0024] (11) The first heating component heats the water in the steam tank to generate steam.

[0025] (12) Steam flows through the intake pipe to the first steam passage and the second steam passage inside the shell.

[0026] (13) When the steam flows to the first steam passage and the second steam passage, the second heating component heats the steam for the second time.

[0027] (14) The steam that has been heated a second time is discharged into the building interior through the outlet of the shell.

[0028] The above method allows the steam entering the shell to be reheated a second time through the first steam channel and the second steam channel. Since the first steam channel and the second steam channel are detour channels formed by I-beams, the length of the steam heating channel is increased, resulting in better steam heating effect.

[0029] Furthermore, the steam condensation mechanism includes a condensation box, a water storage tank, a condensation component, and a condensation fan. The condensation box is located outdoors, and a water storage tank is located inside the condensation box. A condensation channel is formed between the water storage tank and the condensation box. The exhaust fan assembly is connected to the condensation channel. The condensation component is located inside the water storage tank, and a liquid pipe passes through the condensation box and extends into the water storage tank. The water storage tank has a box structure with an opening at the top, formed by splicing the side walls and bottom surface together with a waterproof and breathable layer. A condensation component is located at the opening of the box, and a condensation fan is located above the condensation component.

[0030] The above setup uses a condenser to condense the steam, thereby enabling steam recovery and saving energy.

[0031] Furthermore, the waterproof and breathable layer is made of a material with a density greater than that of the atmosphere and less than that of water.

[0032] The above setup utilizes a water tank made of waterproof and breathable materials. Because the density of gas is less than that of the waterproof and breathable layer, steam can enter the water tank. When the gas is condensed into water by the condensing component, the density of water is greater than that of the waterproof and breathable layer, thus preventing water from seeping out of the water tank. This achieves both gas condensation and prevention of water from being stored inside the water tank.

[0033] Furthermore, step (51) specifically includes:

[0034] (511) Steam is drawn into the condensation channel by the exhaust assembly, and the steam flows in the condensation channel.

[0035] (512) The condenser fan starts to draw the air in the condenser channel into the water storage tank.

[0036] (513) When air enters the water storage tank, the air is condensed by the condensing component to form water and stored in the water storage tank.

[0037] Furthermore, a blower assembly is provided at the air outlet end of the housing. The blower assembly includes a first fan and a blower motor. The blower motor is mounted on the air outlet end of the housing via a blower motor bracket, and the first fan is mounted on the drive shaft of the blower motor.

[0038] The above setup, via the first fan, can accelerate the flow of steam into the room.

[0039] Furthermore, the ventilation assembly includes a second fan and a ventilation motor. A ventilation channel is provided on the wall of the building. The ventilation motor is installed in the ventilation channel through a motor bracket. The second fan is provided on the drive shaft of the ventilation motor.

[0040] The above setup, by incorporating a second fan, can extract indoor steam to the steam condensation mechanism, while simultaneously creating a steam flow direction within the room, allowing steam to flow more effectively from the steam exhaust mechanism to the steam condensation mechanism.

[0041] Furthermore, the pumping assembly includes a pump and a filter component. The filter component is located at one end of the liquid pipeline near the steam condensation mechanism, and the pump is located at the other end of the liquid pipeline near the steam discharge mechanism.

[0042] The above setup uses a water pump to return the condensed water to the steam exhaust mechanism, thereby achieving the recycling of condensate and saving energy. Attached Figure Description

[0048] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0049] like Figures 1 to 5 As shown, a circulating sterilization method is described. This steam sterilization method achieves building sterilization through a steam circulation system. The steam circulation system includes a steam emission mechanism 1, a drying adsorption layer 2, and a steam condensation mechanism 3. The steam emission mechanism 1 is located at the top of building 01, and the steam condensation mechanism 3 is located at the bottom of the exterior of building 01. An exhaust assembly 4 connected to the steam condensation mechanism 3 is also provided inside building 01. The drying adsorption layer 2 is laid on the walls inside building 01. The steam condensation mechanism 3 is connected to the steam emission mechanism 1 via a liquid pipe (not shown in the figure). A water pumping assembly (not shown in the figure) is provided inside the liquid pipe.

[0050] In this embodiment, the drying adsorption layer is a desiccant layer, which is a floor made of desiccant material, specifically existing technology, and will not be described in detail here.

[0051] like Figure 1 and Figure 4As shown, the steam emission mechanism 1 includes a housing 11, a steam tank 12, a first heating component (not shown in the figure), and a second heating component 13. The housing 11 is located on the top of building 01. The air inlet of the housing 11 is located outside the building, and the air outlet of the housing 11 is located inside the building 01. The steam tank 12 is located outside the building 01 and has an opening. The opening is connected to the air inlet of the housing 11 through an air inlet pipe 121. In another embodiment, the housing 11 is located at the top of the building interior, and the air inlet pipe 121 extends into the building 01 and connects to the air inlet of the housing 11. The first heating component is located inside the steam tank 12. A steam channel 14 is provided inside the housing 11 to connect the air inlet and air outlet of the housing 11. A second heating component 13 is provided on the steam channel 14. The liquid pipe is connected to the steam tank 12.

[0052] The above setup heats water to generate steam via a first heating element. As the steam passes through the steam channel, it is reheated by a second heating element, ensuring thorough heating and better sterilization.

[0053] like Figure 1 and Figure 4 As shown, an I-shaped partition 15 is provided in the center of the housing 11. The I-shaped partition 15 includes a main partition 16, a top partition 17 provided at the top of the main partition 16, and a bottom partition 18 provided at the bottom of the main partition 16. The steam passage 14 forms a first steam passage 141 and a second steam passage 142 through the I-shaped partition 15. The first steam passage 141 and the second steam passage 142 are respectively located on both sides of the main partition 16. A second heating component 13 is provided on both sides of the main partition 16.

[0054] By setting the I-shaped baffle 15, the steam entering the steam channel 14 can be divided into two streams, thereby enabling the second heating component 13 to heat the steam more fully.

[0055] A partition plate 19 is also provided at the center of both sides of the housing 11.

[0056] Meanwhile, the arrangement of the top baffle 17, bottom baffle 18 and middle baffle 19 can increase the steam flow path, thereby increasing the steam flow time and allowing the steam to be heated more fully by the second heating component 13.

[0057] The above configuration allows the steam entering the casing to be reheated a second time through the first steam channel and the second steam channel. Since the first steam channel and the second steam channel are through a meandering channel formed by the I-beam partition, the length of the steam heating channel is increased, resulting in better steam heating effect.

[0058] A blower assembly 10 is provided at the air outlet end of the housing 11. The blower assembly 10 includes a first fan 101 and a blower motor 102. The blower motor 102 is mounted on the bottom partition 18 via a blower motor bracket (not shown in the figure), and the first fan 101 is mounted on the drive shaft of the blower motor 102. With the above arrangement, the first fan 101 can accelerate the flow of steam into the room.

[0059] In this embodiment, the first heating component is an evaporator and the second heating component is an air heating tube, which are existing technologies and will not be described in detail here.

[0060] like Figure 2 and Figure 5 As shown, the steam condensation mechanism 3 includes a condensation box 31, a water storage tank 32, a condensation component 33, and a condensation fan 34. The condensation box 31 is located outdoors of building 01. The water storage tank 32 is located inside the condensation box 31. A condensation channel 30 is formed between the water storage tank 32 and the condensation box 31. The exhaust assembly 4 is connected to the condensation channel 30. The condensation component 33 is located inside the water storage tank 32. A liquid pipe passes through the condensation box 31 and extends into the water storage tank 32. The water storage tank 32 is a box structure with an opening at the top, formed by splicing the side walls and bottom surface together with a waterproof and breathable layer 321. The condensation component 33 is located at the opening of the box, and a condensation fan 34 is located above the condensation component 33.

[0061] The above configuration uses the condenser 33 to condense the steam, thereby achieving steam recovery and utilization, and saving energy.

[0062] In this embodiment, the condensing component is a condenser, which is existing technology and will not be described in detail here.

[0063] The waterproof and breathable layer is made of a material with a density greater than that of the atmosphere but less than that of water.

[0064] The above configuration, using a water storage tank 32 made of waterproof and breathable material, allows steam to enter the water storage tank 32 because the density of the atmosphere is less than the density of the waterproof and breathable layer. When the gas is condensed into water by the condensing component, the density of water is greater than the density of the waterproof and breathable layer, thus preventing the water from seeping out of the water storage tank 32. This achieves both condensation of the gas and prevention of water from being stored inside the water storage tank 32. In this embodiment, the material of the waterproof and breathable layer is prior art, such as a waterproof and breathable building material disclosed in Chinese Patent Application No. 201621159478.X, published on May 31, 2017, which discloses a waterproof and breathable material made of polytetrafluoroethylene or TPU film. Another example is a waterproof and breathable building material and its preparation method disclosed in Chinese Patent Application No. 202110187014.9, published on June 15, 2021, which discloses a preparation method of a waterproof and breathable material composed of a polyolefin microporous mold and a non-woven fabric layer. These are specific prior art and will not be described in detail here.

[0065] like Figure 2 As shown, the exhaust assembly 4 includes a second fan 41 and an exhaust motor 42. An exhaust duct 011 is provided on the wall of the building 01. The exhaust motor 42 is installed in the exhaust duct 011 through a motor bracket 43. The second fan 41 is provided on the drive shaft of the exhaust motor 42.

[0066] The above configuration, by setting the second fan 41, can extract indoor steam to the steam condensing mechanism 3, and at the same time can also form a steam flow direction in the room, so that the steam can flow better from the steam emission mechanism to the steam condensing mechanism.

[0067] The water pumping assembly (not shown in the figure) includes a water pump and a filter component. The filter component is located at one end of the liquid pipeline near the steam condensation mechanism, and the water pump is located at the other end of the liquid pipeline near the steam discharge mechanism. In this embodiment, the filter component is a filter screen or other component capable of filtering water, which is existing technology and will not be described further here.

[0068] The above setup utilizes a water pump to return the condensed water to the steam exhaust mechanism, thus achieving condensate recycling and saving energy. Additionally, when the steam tank needs replenishment, water can be added from the storage tank and pumped to the steam tank via the water pump.

[0069] like Figure 3 As shown, a cyclic sterilization method includes the following steps:

[0070] (1) The steam exhaust mechanism heats the water and exhausts steam into the building interior.

[0071] (11) The first heating component heats the water in the steam tank to generate steam.

[0072] (12) Steam flows through the intake pipe to the first steam passage and the second steam passage inside the shell.

[0073] (13) When the steam flows to the first steam passage and the second steam passage, the second heating component heats the steam for the second time.

[0074] (14) The steam that has been heated a second time is discharged into the building interior through the outlet of the shell.

[0075] (2) Steam flows naturally inside the building.

[0076] (3) When steam comes into contact with the wall, the dry adsorption layer adsorbs the steam.

[0077] (4) The exhaust system is activated to extract the air from the room.

[0078] (5) When the steam flows in the direction of the exhaust assembly, the exhaust assembly draws the steam to the steam condensation mechanism.

[0079] (51) The steam condensation mechanism condenses the steam into water to achieve recycling.

[0080] (511) Steam is drawn into the condensation channel by the exhaust assembly, and the steam flows in the condensation channel.

[0081] (512) The condenser fan starts to draw the air in the condenser channel into the water storage tank.

[0082] (513) When air enters the water storage tank, the air is condensed by the condensing component to form water and stored in the water storage tank.

[0083] (6) Water is delivered to the steam discharge mechanism via a pumping assembly.

[0084] The beneficial effects of this invention are as follows: By setting up a steam emission mechanism to heat water to form steam and discharge it into the room, indoor sterilization is achieved. The exhaust assembly draws the steam into the room, creating a steam flow direction that allows the steam to circulate better and improves the sterilization effect. At the same time, by setting up a steam condensation mechanism, the steam can be condensed into water and then transported back to the steam emission mechanism, thus achieving water recycling and saving energy. By first heating the water in the steam tank through a first heating component and then further heating the steam generated by the first heating component through a second heating component, the steam is heated more evenly and reliably, improving the efficiency of steam generation. By first allowing the steam to circulate in the building room and then activating the exhaust assembly, it is ensured that the steam circulates completely in the building room before exhaust, ensuring that the steam can enter the entire room, resulting in a good indoor steam sterilization effect.
