Description

Technical Field

[0001] This invention belongs to the field of building ventilation technology, and in particular relates to an energy-saving building ventilation device. Background Technology

[0002] Building ventilation is a measure taken to ensure fresh and comfortable air inside a building. Good building ventilation can maintain indoor air circulation, remove harmful gases and odors, regulate indoor temperature and humidity, improve indoor air quality, and provide a comfortable environment.

[0003] Currently, urban residential buildings are generally equipped with fresh air systems during construction, which, together with indoor intelligent monitoring devices, can exchange indoor air in a timely manner. However, in rural areas, due to the abundance of greenery and better air quality, as well as the ease of indoor-outdoor air exchange, the demand for fresh air systems in rural areas is not significant.

[0004] However, for rural indoor toilets, the space is usually small, and the feces produce an unpleasant odor during daily use, so the toilet needs frequent ventilation. To ensure the privacy of the toilet, usually only a non-powered exhaust fan or an electric exhaust fan is installed high on the wall to achieve the purpose of ventilation. Although the non-powered exhaust fan can ventilate the toilet without a power supply, it is greatly affected by the airflow speed around the building and the building structure, and its ventilation is relatively passive and the ventilation effect is not good. While the electric exhaust fan can provide a better ventilation effect, the long-term operation of the exhaust fan is not energy-efficient. Moreover, since the toilet or squat toilet is located on the floor of the toilet and the exhaust fan is located high up, the odor produced by the feces cannot be dissipated in time, affecting the ventilation effect of the toilet.

[0015] Compared with existing technologies, the advantages of a building energy-saving ventilation device are:

[0016] 1. Through the coordinated installation of the drain riser and drain bend, it can serve as the drain pipe for toilets or squat toilets. Furthermore, through the coordinated installation of the elastic airbag, suction pipe, insulating cylinder, exhaust pipe, one-way valve, cylinder, mounting box, ventilation pipe, exhaust fan, supply fan, controller, conical suction hole, and triggering mechanism, it can automatically absorb odorous air after urination by using the flushing water to generate self-suction. After defecation, it automatically triggers ventilation in the toilet. This not only allows for automatic ventilation based on the type of feces, promoting energy conservation and reducing consumption, but also ensures that odors from feces dissipate promptly by ventilating the area around the toilet or squat toilet.

[0017] 2. The air supply and heat exchange components allow for sufficient heat exchange between the air intake and exhaust channels when ventilating the toilet after defecation. This effectively reduces temperature fluctuations in the toilet caused by ventilation, thus reducing the workload of indoor temperature control equipment and improving comfort when using the toilet. Furthermore, the adsorption mechanism removes odors from the exhaust air, preventing odors from directly affecting the external air environment.

[0018] 3. The differential pressure unblocking mechanism can create a negative pressure state in the drain pipe by using an exhaust fan when the toilet or squat toilet is blocked. The pressure difference between the inside and outside can help to discharge the blocked feces, thus achieving the effect of unblocking and clearing the blockage. The automatic flushing mechanism can automatically flush the feces after a person defecates, thereby ensuring that the air in the bathroom is replaced with fresh air in a timely manner and that the ventilation in the bathroom is timely.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] like Figures 1-7 As shown, a building energy-saving ventilation device includes a sewage riser 1 and a sewage bend 2. The sewage bend 2 is connected to the sewage riser 1. An elastic airbag 3 is fixedly installed on the vertical part of the sewage bend 2, and the elastic airbag 3 is arranged in a ring. An air intake pipe 4 is fixedly inserted into the side wall of the sewage bend 2, and the air intake pipe 4 is connected to the elastic airbag 3. An insulating cylinder 5 is fixedly inserted into the side wall of the sewage bend 2, and the insulating cylinder 5 is connected to the elastic airbag 3. An exhaust pipe 6 is fixedly inserted into the end of the insulating cylinder 5. Both the exhaust pipe 6 and the air intake pipe 4 are equipped with one-way valves 7. The top of the sewage riser 1 is sealed, and a cylinder 8 is fixedly inserted into the top of the sewage riser 1. The cylinder 8 is connected to the exhaust pipe 1. The air pipe 6 is connected to the top of the cylinder 8, and the top of the cylinder 8 is fixedly connected to the mounting box 9. The top of the mounting box 9 is fixedly installed with an exhaust fan 11 and an air supply fan 12. The intake end of the exhaust fan 11 is connected to the mounting box 9. The exhaust end of the air supply fan 12 is installed with an air supply heat exchange component 13. The air supply heat exchange component 13 includes a heat exchange pipe 131 fixedly installed at the exhaust end of the air supply fan 12. The heat exchange pipe 131 is installed through the side wall of the cylinder 8. The end of the heat exchange pipe 131 is fixedly installed with an insulation pipe 132. When the outside air enters the bathroom through the heat exchange pipe 131, it can exchange heat with the air exhausted from the bathroom, thereby reducing the impact of ventilation on the temperature inside the bathroom.

[0029] The wall of the insulation pipe 132 is fixedly connected to a hollow column 21. A liquid storage sleeve 22 is fixedly installed inside the hollow column 21. The liquid storage sleeve 22 is filled with disinfectant fragrance 23. Multiple ventilation holes 24 are opened at the upper end of the side wall of the liquid storage sleeve 22. An exhaust hole 25 is opened at the end of the hollow column 21. The disinfectant fragrance 23 is made of disinfectant alcohol and fragrance material. Disinfectant alcohol can disinfect and sterilize the air to a certain extent, while fragrance material can keep the air in the bathroom with a certain fragrance.

[0030] A second electromagnetic switch 26 is fixedly installed inside the insulating casing 5, and the second electromagnetic switch 26 is electrically connected to the conductive rod 182 and the conductive slip ring 184. An ultraviolet disinfection lamp 27 is fixedly installed on the upper side of the inside of the casing 15. The second electromagnetic switch 26 is electrically connected to the ultraviolet disinfection lamp 27 through the controller 16. When the conductive rod 182 and the conductive slip ring 184 come into contact, the second electromagnetic switch 26 will be immediately turned on. At this time, the controller 16 will immediately control the ultraviolet disinfection lamp 27 to work, and the ultraviolet disinfection lamp 27 can disinfect and sterilize the inside of the casing 15.

[0031] An adsorption mechanism 14 is installed inside the installation box 9. A box 15 is fixedly installed at the end of the suction pipe 4, and a controller 16 is fixedly installed on the side wall of the box 15. Multiple conical suction holes 17 are opened on the side wall of the box 15. The adsorption mechanism 14 includes a stainless steel baffle 141 fixedly installed inside the installation box 9, and multiple adsorption carbon bags 142 are filled in the position of the stainless steel baffle 141 inside the installation box 9. The adsorption carbon bags 142 can adsorb and purify odors in the air and prevent odors from entering the outside air.

[0032] The elastic airbag 3 and the insulating cylinder 5 are jointly equipped with a triggering mechanism 18. The triggering mechanism 18 can automatically trigger the operation of the exhaust fan 11 and the air supply fan 12 according to the feces through the controller 16. The triggering mechanism 18 includes an insulating pad 181 fixedly disposed on the inner wall of the elastic airbag 3, and a conductive rod 182 is fixedly installed on the side wall of the insulating pad 181. An insulating limit block 183 is fixedly installed on the inner wall of the insulating cylinder 5, and the insulating limit block 183 is slidably connected to the conductor rod. A conductive slip ring 184 is fixedly installed on the inner wall of the insulating cylinder 5. A first electromagnetic switch 185 is fixedly installed on the inner wall of the insulating cylinder 5, and the first electromagnetic switch 185 is electrically connected to the exhaust fan 11 and the air supply fan 12 through the controller 16. The conductive slip ring 184 and the conductive rod 182 are electrically connected to the first electromagnetic switch 185. Changing the contact position between the conductive rod 182 and the conductive slip ring 184 can change the resistance of the connection circuit of the first electromagnetic switch 185, the conductive rod 182 and the conductive slip ring 184.

[0033] The cylinder 8 and the exhaust pipe 6 are jointly equipped with a differential pressure unblocking mechanism 19. The differential pressure unblocking mechanism 19 can assist in the discharge of blocked feces. The differential pressure unblocking mechanism 19 includes a negative pressure suction hole 191 opened at the bottom of the cylinder 8, and a normally closed solenoid valve 192 is installed inside the negative pressure suction hole 191. A normally open solenoid valve 193 is installed inside the exhaust pipe 6. Both the normally closed solenoid valve 192 and the normally open solenoid valve 193 are electrically connected to the controller 16. A U-shaped tube 194 connected to the negative pressure suction hole 191 is fixedly installed at the end of the cylinder 8. An electromagnetic gate valve 195 electrically connected to the controller 16 is installed inside the sewage vertical pipe 1 below the U-shaped tube 194. When the electromagnetic gate valve 195 is energized, it can attract the gate to seal the sewage vertical pipe 1. When the electromagnetic gate valve 195 is de-energized, its gate will rebound and reset under the action of its own elastic element and open the sewage vertical pipe 1.

[0034] The housing 15 is equipped with an automatic flushing mechanism 20, which is used for automatic flushing of feces. The automatic flushing mechanism 20 includes a fixed plate 201, on the side wall of which a first proximity switch 202 and a second proximity switch 203 are fixedly installed. A power-off delay relay 204 is fixedly installed inside the housing 15. An adjustable plate 205 is fixedly installed on the side wall of the housing 15, and an electromagnetic push rod 206 is fixedly inserted into the end face of the adjustable plate 205. A pressing hemisphere 207 is fixedly installed at the output end of the electromagnetic push rod 206. The first proximity switch 202 is electrically connected to the second proximity switch 203, the power-off delay relay 204, and the electromagnetic push rod 206 via a controller 16. Both the first proximity switch 202 and the second proximity switch 203 are based on the infrared sensing principle. When personnel... When approaching, the person's legs will block and reflect part of the infrared rays emitted by the infrared emitter. When the infrared receiver receives the reflected infrared rays, it will generate a corresponding electrical signal. The electromagnetic push rod 206 includes components such as an electromagnet, a magnetic block, a push rod, an elastic element, and a non-magnetic cylinder. When the electromagnet is energized, it will generate magnetic force. Under the repulsive force of like poles, it can push the magnetic block to drive the push rod out. When the electromagnet is de-energized, the push rod can be moved back to its original position under the action of the elastic element. This is a mature existing technology, so it will not be described in detail here. The adjustable plate 205 includes components such as a fixed plate, a movable plate, and bolts. The movable plate is slidably set on the fixed plate. The bolts can lock and fix the fixed plate and the movable plate. By adjusting the extension length of the movable plate, the position of the electromagnetic push rod 206 can be adjusted.

[0035] The operating principle of the present invention is explained as follows: When constructing a toilet in a rural area, the sewage vertical pipe 1 and sewage bend 2 are pre-embedded. Then, the drain outlet of the toilet or squat toilet is connected to the sewage bend 2, and the machine box 15 is installed on the inner wall of the toilet, and the installation box 9 is fixed to the outer wall of the toilet. Subsequently, the insulation pipe 132 is reasonably laid out so that the air outlet end of the insulation pipe 132 is located on the upper side of the toilet room. Then, the fixing plate 201 is fixed on the inner wall of the toilet, and the fixing plate 201 is aligned with the leg position of the person using the toilet or squat toilet. Then, an appropriate amount of disinfectant fragrance 23 is poured into the liquid storage sleeve 22, and an appropriate amount of adsorbent carbon bag 142 is placed inside the installation box 9. Then, the position of the electromagnetic push rod 206 is adjusted by the adjustable plate 205 so that the pressing hemisphere 207 is located above the drain button of the toilet (or squat toilet). Finally, the power supply circuit of the controller 16 is turned on.

[0036] When a person is defecating, they will approach the toilet or squat toilet. At this time, both the first proximity switch 202 and the second proximity switch 203 will detect the person's arrival (both the first proximity switch 202 and the second proximity switch 203 are based on the principle of infrared sensing; when a person approaches, their legs will block and reflect part of the infrared light emitted by the infrared emitter, and when the infrared receiver receives the reflected infrared light, it will generate a corresponding electrical signal). The first proximity switch 202 will immediately supply power to the connection circuit between the second proximity switch 203, the power-off delay relay 204, and the electromagnetic push rod 206 through the controller 16. When the second proximity switch 203 detects the person's arrival, it will keep the connection circuit between the second proximity switch 203, the power-off delay relay 204, and the electromagnetic push rod 206 in an open state. Therefore, the electromagnetic push rod 206 will not work at this time, and the person will defecate. Afterwards, since the personnel have moved away from the first proximity switch 202 and the second proximity switch 203, both the first proximity switch 202 and the second proximity switch 203 will immediately reset. When the second proximity switch 203 resets, within the 15-second delay of the power-off timeout relay 204, the connection circuit between the second proximity switch 203, the power-off timeout relay 204, and the electromagnetic push rod 206 will remain energized. Since the second proximity switch 203 has reset, the electromagnetic push rod 206 will be energized. When the electromagnetic push rod 206 is energized, the electromagnet inside it will generate magnetic force. Under the repulsive force of like poles, it can push the magnetic block inside it to push the push rod out, thereby driving the pressing hemisphere 207 to move down, and thus pressing the water filling switch of the toilet (or squat toilet) to automatically drain the toilet (or squat toilet), thereby flushing the feces into the drain pipe 2.

[0037] When feces enter the drain bend 2 with the flushing water, the feces and water compress the elastic airbag 3. At this time, the air inside the elastic airbag 3 enters the cylinder 8 through the insulating cylinder 5 and the exhaust pipe 6. Simultaneously, due to the compression of the elastic airbag 3, it moves the conductive rod 182 via the insulating pad 181, causing the conductive rod 182 to contact the conductive slip ring 184. When a person urinates, because urine is liquid, it mixes with the flushing water and is discharged through the drain bend 2, resulting in less compression of the elastic airbag 3. In this case, the contact position between the conductive slip ring 184 and the conductive rod 182 is located on the left side of the conductive rod 182. Therefore, the length of the conductive rod 182 connected to the conductive slip ring 184 and the first electromagnetic switch 185 is relatively long. Because the resistance of the connection circuit between the conductive rod 182, the conductive slip ring 184, and the first electromagnetic switch 185 is relatively high, the first electromagnetic switch 185 cannot receive sufficient current. Therefore, the first electromagnetic switch 185 does not... The elastic airbag 3 will close, so after urine is discharged into the sewage riser 1 along with the water, the elastic airbag 3 will immediately return to its original position under its own elasticity. At this time, under the pressure difference between the inside and outside of the elastic airbag 3, and because the box 15 is located at the toilet or squat toilet, the odorous air generated during urination will be quickly sucked into the box 15 and the elastic airbag 3 through the conical air intake 17, thereby minimizing the odor generated during urination from dissipating in the toilet. If a person defecates, when the feces and the flushing water pass through the elastic airbag 3, the feces exert greater pressure on the elastic airbag 3 (because the elastic airbag 3 is located in the vertical part of the sewage bend 2, the impact of water flow and the falling impact of water flow and feces makes it less likely for feces to block at the elastic airbag 3). At this time, the length of the conductive rod 182 connected to the conductive slip ring 184 and the first electromagnetic switch 185 in the connection circuit is relatively short, so the current flowing into the first electromagnetic switch 185 is larger. At this time, the moving contact of the first electromagnetic switch 185 will magnetically close.

[0038] After the moving contact of the first electromagnetic switch 185 closes, it sends an electrical signal to the controller 16. The controller 16 then immediately controls the exhaust fan 11 and the air supply fan 12 to operate for 5 minutes at a set time. The exhaust fan 11, through the mounting box 9, cylinder 8, exhaust pipe 6, insulating cylinder 5, elastic airbag 3, suction pipe 4, and housing 15, generates negative pressure suction in the conical suction hole 17, thus continuously suctioning the toilet for 5 minutes. This effectively removes odors from feces, and combined with the adsorption and purification of odors by the adsorbent charcoal bag 142, it can prevent... Odors dissipate into the outside air, and when the exhaust fan 11 is working, the air pressure difference inside the elastic airbag 3 is less than the pressure difference outside. At this time, the elastic airbag 3 will be compressed under the action of pressure difference. Therefore, even if feces are blocked in the elastic airbag 3, the feces and water will still squeeze the elastic airbag 3 under their own weight, causing the moving contact of the first electromagnetic switch 185 to close. At this time, the negative pressure generated by the exhaust fan 11 will still cause the elastic airbag 3 to be in a large compression state, so that the blocked feces can continue to be discharged.

[0039] When the air supply fan 12 is working, it can deliver fresh air from outside to the interior of the insulation pipe 132 through the heat exchange pipe 131. When the outside air passes through the heat exchange pipe 131, it can exchange heat with the air in the bathroom that passes through the cylinder 8, so that the temperature of the air entering the bathroom is not much different from the original temperature in the bathroom, reducing the impact of ventilation on the temperature in the bathroom. When the outside air passes through the insulation pipe 132, some of the air will be diverted into the interior of the hollow column 21, and through the ventilation hole 24 and the exhaust hole 25, it will carry the volatilized disinfectant fragrance 23 into the bathroom, thereby disinfecting and sterilizing the air in the bathroom to a certain extent.

[0040] When the conductive rod 182 and the conductive slip ring 184 come into contact, the second electromagnetic switch 26 will be immediately activated. At this time, the controller 16 will receive the electrical signal from the second electromagnetic switch 26, and the controller 16 will immediately control the ultraviolet disinfection lamp 27 to work for 5 minutes. When the ultraviolet disinfection lamp 27 is working, it can disinfect and sterilize the inside of the box 15, preventing the growth of bacteria from the odorous air sucked into the box 15.

[0041] When a toilet or squat toilet becomes clogged, the user presses the unblocking button on the controller 16. At this time, the controller 16 will immediately energize the exhaust fan 11, the normally closed solenoid valve 192 in the negative pressure suction hole 191, the normally open solenoid valve 193 in the exhaust pipe 6, and the solenoid gate valve 195 in the sewage riser 1. At this time, the exhaust fan 11 can expel the air inside the sewage bend 2 through the mounting box 9, the cylinder 8, and the U-shaped pipe 194. At this time, the pressure upstream of the blockage is greater than the air pressure downstream of the blockage. Under the action of pressure difference, the blockage can be pushed through the sewage bend 2 into the sewage riser 1, and finally into the septic tank.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
