Referring to fig. 1, fig. 1 is a schematic view of a toilet air conditioning system 10 according to the present invention. To achieve at least one of the above advantages or other advantages, an embodiment of the present invention provides a toilet air conditioning system 10 disposed in a toilet 12, the toilet 12 including a plurality of toilets 122, the toilets 122 being toilet tools such as toilets, squats, urinals, etc. The toilet air conditioning system 10 includes an exhaust channel 14, an air supply channel 16, a detection module 18, an exhaust fan 20 and an air supply fan 22.
The detection module 18 is disposed in the toilet 12 and generates a detection signal. The detection signal corresponds to the amount of use of the toilet 122 in the toilet 12 or the amount of odor in the toilet 12. In one embodiment, the detection module 18 includes an odor detector and an infrared sensor. The odor detector is disposed in the toilet 12 for detecting the content of odor in the toilet 12. The infrared sensors are respectively disposed around the toilets 122 for detecting whether a person approaches the toilet 122 to determine the number of used toilets 122 in the toilet 12. When the detection module 18 detects that the amount of odor in the toilet 12 exceeds a predetermined alarm line or detects that the toilet 122 is being used, the exhaust fan 20 starts to operate to exhaust the odor in the toilet 12. That is, the exhaust fan 20 is started to exhaust only when any one of the conditions is satisfied. In addition, the detection module 18 may also use other sensing devices such as an audio sensor, a photoelectric sensor, etc. to detect whether a person uses the toilet 122. In another embodiment, when the toilet 12 includes a plurality of individual toilets, and each individual toilet includes a toilet 122, the detection module 18 may be installed at the doorway of each individual toilet.
The exhaust fan 20 is connected to the exhaust passage 14 to exhaust the air in the toilet 12. The exhaust fan 20 controls the amount of exhaust air according to the detection signal, and exhausts the odor in the toilet 12 with an appropriate amount of exhaust air. For example, if the detection signal corresponds to the number of used toilets 122 in the toilet 12, when the detection module 18 detects that the number of used toilets 122 in the toilet 12 is 3, 4 or 5, the exhaust amount of the exhaust fan 20 is 60-90 m3/h、80～120m3/h、100～150m3The exhaust fan 20 corresponding to one toilet 122 has an exhaust volume of about 20 to 30m3H is the ratio of the total weight of the catalyst to the total weight of the catalyst. If the detection signal corresponds to the odor content in the toilet 12, when the detection module 18 detects that the odor content in the space of the toilet 12 is respectively low, medium and high, the air displacement of the exhaust fan 20 is respectively corresponding to three levels of small, medium and large, so as to exhaust the odor in the toilet 12 with a suitable air displacement, reduce unnecessary wind power and save power.
The air supply fan 22 is connected to the air supply passage 16 to supply air to the toilet 12, so as to realize the operation of supplying air while exhausting air, and ensure sufficient air in the toilet 12 to meet the use requirement. In one embodiment, the exhaust fan 20 and the make-up fan 22 are operated synchronously, that is, when the exhaust fan 20 starts to operate to exhaust the odor in the toilet 12, the make-up fan 22 is operated synchronously to replenish the air in the toilet 12; when the exhaust fan 20 stops operating, the make-up air fan 22 follows the synchronous stop. In addition, the amount of make-up air of the make-up air blower 22 is substantially equal to the amount of exhaust air of the exhaust air blower 20, so as to further ensure sufficient air in the toilet 12.
In one embodiment, as shown in FIG. 1, the exhaust passage 14 includes a plurality of first exhaust ports 142, second exhaust ports 144, and a first switching valve 146. The first exhaust ports 142 are respectively provided around the toilets 122 so as to draw the odor near the toilets 122 into the exhaust passage 14. The second exhaust port 144 is located on the wall or ceiling of the toilet 12 to exhaust the odor throughout the toilet 12. The first switching valve 146 is used to selectively connect the first exhaust port 142 or the second exhaust port 144 to the exhaust fan 20. For example, when the number of used toilets 122 in the toilet 12 is small, the first switching valve 146 connects the first exhaust port 142 to the exhaust fan 20 to extract the odor around the used toilet 122; when the number of the toilets 122 in the toilet 12 is large, the first switching valve 146 connects the second exhaust port 144 to the exhaust fan 20 to directly exhaust the odor in the toilet 12. Alternatively, when the odor content in the toilet 12 is excessive, the first switching valve 146 connects the second exhaust port 144 to the exhaust fan 20 to directly exhaust the entire odor in the toilet 12.
Further, the exhaust passage 14 may further include a plurality of choke valves 24 respectively disposed on the first exhaust port 142 and connected to the exhaust pipe 149 of the exhaust fan 20 for selectively exhausting air to the toilet 122. The flow rate of the gas flowing to the exhaust fan 20 through the first exhaust port 142, that is, the exhaust amount of the first exhaust port 142 is controlled. For example, each of the first exhaust ports 142 is connected to an exhaust pipe 149 of the air collecting duct 148, and a choke valve 24 is disposed thereon. When the exhaust fan 20 is started, the choke valve 24 of the used toilet 122 corresponding to the first exhaust port 142 is opened to exhaust the odor in the toilet 12; when the exhaust fan 20 stops operating, the choke valve 24 is closed to prevent gas from passing therethrough to selectively exhaust the toilet 122 for use. In addition, the choke valve 24 can be controlled by wireless signals, wired connection, etc.
In one embodiment, as shown in fig. 1, the detection module 18 includes a plurality of detectors 182, which are disposed in a one-to-one correspondence with the toilets 122. In other words, each toilet 122 is correspondingly provided with a detector 182 for detecting the usage of the toilet 122 or the odor content around the toilet 122 to generate a detection signal. However, the present invention is not limited thereto. The detection module 18 can be installed at the gate to detect the amount of odor in the toilet 12 or to calculate the usage of the toilet 122 in the toilet 12 by detecting the number of people entering or exiting the toilet 12. It should be noted that when the number of persons in the toilet 12 is greater than the total number of the toilets 122 in the toilet 12, the total number of the toilets 122 should be the number of the toilets 122 being used.
In one embodiment, as shown in fig. 1, the air supply passage 16 includes a first air supply port 162, a second air supply port 164 and a second switching valve 166. The first air supplement opening 162 is connected to the outside of the room to supplement the outside air into the toilet 12. The second air supplement port 164 is connected to an indoor space, such as an office on the same floor, for supplementing indoor cool air to the toilet 12, thereby reducing power consumption of cool air of the air conditioner. The second switching valve 166 is used to selectively connect the first air supplement port 162 or the second air supplement port 164 to the air supplement blower 22. Generally, when the toilet 12 is hot and cold, the second switch valve 166 connects the second air supplement port 164 to the air supplement fan 22.
Referring to fig. 2, fig. 3A and fig. 3B, fig. 2 is an exploded view of the choke valve 24 of the present invention, fig. 3A is a schematic view of the choke valve 24 of the present invention when opened, and fig. 3B is a schematic view of the choke valve 24 of the present invention when closed. As shown, the choke valve 24 includes a housing 242, a motor 244, an endless chain 245, a plurality of rotating plates 246, and a plurality of gears 248. The middle region of the shell 242 has a hollow-out region 243. A plurality of rotating plates 246 are movably installed inside the housing 242 and arranged around the hollow area 243 in an array, and each rotating plate 246 is correspondingly provided with a gear 248. The chain 245 is engaged with the gears 248. The motor 244 is connected to the housing 242 and drives the plurality of gears 248 to rotate through the chain 245, so that the plurality of rotating plates 246 switch back and forth between sealing the hollow area 243 and opening the hollow area 243. Specifically, as shown in fig. 3A, when the choke valve 24 is about to allow air to flow, the motor 244 starts to operate and drives the gear 248 to rotate clockwise through the chain 245, so as to drive the rotating plate 246 to open, exposing the hollow area 243, and allowing the air to pass through; as shown in fig. 3B, when the choke valve 24 is about to block the air flow, the motor 244 starts to operate and drives the gear 248 to rotate counterclockwise through the chain 245, so as to drive the rotating plate 246 to close, and fill the hollow area 243 to prevent the air flow from passing through.
It should be noted that the exhaust fan 20 can be a variable frequency exhaust fan or a plurality of fans with fixed wind power, so as to realize the design that the exhaust fan 20 can control the exhaust volume according to the detection signal.
In summary, the toilet air conditioning system 10 of the present invention can remove the odor in the toilet 12 with a suitable amount of air discharged by the exhaust fan 20 and the detection module 18, remove the moisture in the toilet 12, reduce the cost, and save the power. In addition, by means of the air supply fan 22, the operation of air supply while exhausting can be realized, and the sufficient air in the toilet can be ensured so as to meet the use requirement.
