DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0011] The following examples are each a preferred specific example of the present disclosure. In addition, in each drawing, the same reference numerals are used to denote substantially the same components, and redundant explanations will be omitted or simplified.

[0012] Example 1 As shown in Fig. 1, the air blowing system 1 is provided in a space 91 having a toilet bowl 95. The space 91 is also called a toilet space.

[0013] The space 91 is surrounded by a ceiling 92, a wall 93, and a floor 94. In the vicinity of the toilet 95, the area around the floor 94 is often a source of odor.

[0014] The air blowing system 1 includes an air blowing device 2 and an exhaust port 3 .

[0015] The blower 2 has a housing 21, a blower section 22, an inlet 23, and an outlet 24.

[0016] The housing 21 has a top surface 211, a front surface 212, and side surfaces 213. The housing 21 is installed on a wall surface 93 at a position closer to the ceiling 92 than to the floor surface 94.

[0017] The blower 22 (fan) is provided inside the housing 21.

[0018] The suction port 23 is provided on the upper surface 211, for example.

[0019] The air outlet 24 is provided on the front surface 212, for example.

[0020] A plurality of blowers 2 may be provided along a direction parallel to the floor surface 94 .

[0021] The lining 4 has an upper cover 41 and a front cover 42 .

[0022] The exhaust port 3 is provided in the front cover 42 of the lining 4 . Next, the operation of the ventilation system 1 will be described.

[0023] The blower 2 uses the blower section 22 to suck air from the space 91 through the inlet 23 and blow it out through the outlet 24. The air blown out from the outlet 24 flows in a direction parallel to the floor surface 94.

[0024] On the other hand, as shown in Figure 2, the air in the space 91 sucked in through the exhaust port 3 passes through the inside of the lining 4 and the exhaust duct 31, and is exhausted to the outdoors from the exhaust device 32 installed above the ceiling 92.

[0025] In FIG. 2, the exhaust port 3 is connected to the exhaust device 32 by an exhaust duct 31, but if the airtightness inside the lining 4 can be maintained, the duct connecting the exhaust ports 3 inside the lining 4 may be eliminated and the inside of the lining 4 may be used as a chamber.

[0026] As shown in FIG. 3(a), when the blower 2 is not present, part of the air in the space 91 is sucked into the exhaust port 3 from a wide range of different directions (angles) with the exhaust port 3 as the reference point.

[0027] In this case, in the space 91, air is drawn into the exhaust port 3 from areas other than the periphery of the floor surface 94, so it can be said that the exhaust efficiency of the air containing a lot of odor is not high.

[0028] On the other hand, as shown in FIG. 3(b), when the blower 2 is present, the airflow blown out from the blower 2 zones (divides) the air near the ceiling 92 and the air near the floor surface 94.

[0029] In this case, compared to when the blower 2 is not provided, the air near the odor source can be sucked in through the exhaust port 3 more intensively.

[0030] In this way, the air blowing system 1 can efficiently exhaust the air around the floor surface 94, which is the source of the odor.

[0031] Example 2 In this embodiment, the same components as those in the other embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0032] As shown in FIGS. 4 and 5, the air blower 2 includes a housing 21, an air blower 22, an inlet 23, an outlet 24, a louver 25, a fragrance generator 26, a controller 27, and a human sensor 28.

[0033] The control unit 27 controls the operation of the louver 25 and / or the fragrance emitting unit 26 based on a signal from the human sensor 28.

[0034] The scent generating unit 26 receives a signal from the control unit 27 and starts or stops spraying the scent.

[0035] 4, when human presence sensor 28 does not detect a person, control unit 27 adjusts the angle of louver 25 so that the air blown out from air outlet 24 is parallel to floor surface 94. At this time, a portion of the air blown out from air outlet 24 returns to air inlet 23 and is circulated.

[0036] As shown in Figure 5, when motion sensor 28 detects a person, control unit 27 adjusts the angle of louver 25 so that a portion of the air blown out from air outlet 24 is blown toward the person's location. This allows the scent generated from scent generating unit 26 to be delivered to the person's location. At this time, a portion of the air blown out from air outlet 24 circulates by returning to air inlet 23. This allows the scent to be felt even with a small amount of scent component.

[0037] At this time, a portion of the air blown out from the air outlet 24 is maintained parallel to the floor surface 94. This makes it possible to maintain a zoning (compartmentalized) state between the air near the ceiling 92 and the air near the floor surface 94.

[0038] In this way, the air supply system 1 can deliver a pleasant scent to a person's location while maintaining the efficiency of exhausting odorous air.

[0039] The louver 25 may be made up of, for example, two plates, one of which is fixed so that air is always blown out parallel (horizontally), and the other of which may be adapted to change the angle from parallel (horizontally) upon receiving a signal from the control unit 27.

[0040] For example, the louver 25 may be divided into parts, and the parts other than the divided parts may be fixed so that the air is always blown out parallel (horizontally), and only the divided parts may be able to change their angle from parallel (horizontally) in response to a signal from the control unit 27.

[0041] When the human presence sensor detects a person, it is preferable that the louver 25 be controlled so that the angle of the air blown out from the air outlet 24 is tilted downward by 45 to 75 degrees with respect to the horizontal direction. Next, the operation of the ventilation system 1 will be described.

[0042] As shown in FIG. 6, for example, when the human sensor 28 detects a person, a signal is sent to the control unit 27.

[0043] Based on the signal, the control unit 27 causes the fragrance generating unit 26 to start spraying the fragrance.

[0044] As shown in FIG. 5, the control unit 27 changes the angle of the louvers 25 to obliquely downward.

[0045] After that, when a predetermined time (for example, 10 seconds) has elapsed, the control unit 27 stops the fragrance generation unit 26 from spraying the fragrance.

[0046] As shown in FIG. 4, the control unit 27 switches the angle of the louvers to the horizontal direction.

[0047] After that, for a predetermined time (for example, 10 seconds), the state remains the same even if the human sensor 28 detects a person.

[0048] In the flowchart of Figure 6, the order of "starting fragrance spray from the fragrance generating unit" and "switching the louver direction diagonally downward" can be simultaneous or reversed. Similarly, the order of "stopping fragrance spray from the fragrance generating unit" and "switching the louver direction horizontally" can be simultaneous or reversed.

[0049] As shown in the flowchart of Figure 6, control unit 27 controls scent generation unit 26 to spray scent and adjust the angle of louver 25 only for a predetermined time after motion sensor 28 detects a person. This makes it possible to reduce consumption of scent components such as aroma oil. It is possible to continue spraying scent throughout the period during which motion sensor 28 is detecting a person, but in this case, people's sense of smell gradually becomes accustomed to the scent and they become less able to detect it, so it is sufficient to spray scent only for a predetermined time after motion sensor 28 detects a person.

[0050] (supplement) Below, additional information will be provided regarding each example.

[0051] The exhaust port 3 is installed in the front cover 42 of the lining 4, but the lining 4 may be omitted. For example, if the lining 4 is not installed, the exhaust port 3 may be installed in the wall surface 93 on which the toilet bowl 95 is installed.

[0052] The toilet bowl 95 is assumed to be a urinal, but may also be a toilet bowl.

[0053] The exhaust port 3 is preferably installed at a height of 1000 mm or less, or at a height of 200 to 500 mm from the floor surface 94 .

[0054] The blower 2 may be fixed to the ceiling 92 by a hanger instead of being installed on the wall 93 of the space 91 .

[0055] By providing the intake port 23 of the blower device 2 on the upper surface 211 of the housing 21, which is far from the floor surface 94 that is the source of the odor, it is possible to further prevent the odor from being drawn into the intake port 23. In Patent Document 1, the air outlet is installed near the person's head, and the distance from the floor surface is not far enough, so the air near the odor source is attracted by the airflow blown out from the air outlet, making it difficult for the odor to reach the person. It becomes smaller.

[0056] The total volume of air blown out from outlet 24 is preferably in the range of one-half to one-fourth of the total volume of exhaust air passing through exhaust port 3. If the volume of air blown out from outlet 24 falls below this range, the zoning effect of the blown airflow will be reduced, and the odor suppression effect will be reduced. If the volume of air blown out from outlet 24 exceeds this range, the blown airflow will be more likely to disturb the airflow around the odor source, and the odor suppression effect will be reduced. However, even if the volume of air blown out from outlet 24 is outside this range, the zoning effect will still be achieved, and so it can be said that there is an odor suppression effect.

[0057] Air outlet 24 is preferably installed at a height of 2000 mm or more above floor surface 94. Air outlet 24 is also preferably installed at a distance of 50 to 500 mm from ceiling 92. This is because air outlet 24 is installed at a position higher than a person's head, making it less likely that the air near floor surface 94, which is the source of odor, will be attracted by the airflow blown out from air outlet 24.

[0058] The airflow emitted from the air outlet 24 is blown out so as to be parallel to the floor surface 94. Here, "parallel" does not necessarily mean perfectly parallel, but also includes a state where the angle is off by approximately ±3° or less. Because the airflow is blown out horizontally from the air outlet 24, which is located higher than the user's head, the user is unlikely to sense the airflow near their head and is unlikely to feel any discomfort.

[0059] The fragrance generating unit 26 does not have to be one that operates in response to a signal from the control unit 27. For example, the fragrance generating unit 26 may be one that constantly volatilizes fragrance components.

[0060] (Item 1) A ventilation system 1 including a ventilation device 2 and an exhaust port 3, The air blower 2 has a housing 21, an air blower 22, an air inlet 23, and an air outlet 24. The housing 21 is provided near a wall surface 93 of a space 91 having a toilet bowl 95, The blower 22 is provided in the housing 21, The toilet bowl 95 is provided on the wall surface 93, The wall surface 93 has an exhaust port 3 at a height position of 1000 mm or less from the floor surface 94, The exhaust port 3 is connected to an exhaust device 32, The exhaust device 32 exhausts a portion of the air in the space 91 to the outside of the space 91 through the exhaust port 3, The air outlet 24 is located at a height of 2000 mm or more from the floor surface 94. The blower unit 22 may be configured as a blower system 1 that sucks in air from an inlet 23 and blows it out horizontally from an outlet 24.

[0061] According to this configuration, the airflow blown out from the blower 2 zones (compartments) the air near the ceiling 92 of the space 91 from the air near the floor 94, thereby improving the exhaust efficiency of the exhaust port 3 near the floor 94, which is the source of the odor.

[0062] (Item 2) The intake port 23 may be configured to be provided on the upper surface 211 of the housing 21.

[0063] According to this configuration, by providing intake port 23 of blower device 2 at a position far away from floor surface 94, which is the source of odor, it is possible to prevent odor from being sucked into intake port 23.

[0064] (Item 3) The wall 93 includes a lining 4; The lining 4 includes a front cover 42 and an upper cover 41. A pipe through which water flows is provided inside the lining 4, The exhaust port 3 may be provided in the front cover 42 below the center of the front cover 42 .

[0065] According to this configuration, by utilizing the existing lining 4, odors can be exhausted from the exhaust port 3 without creating new duct space to connect the exhaust ports 3 to each other within the lining 4.

[0066] (Item 4) The air blower 2 has a fragrance generating unit 26, a human sensor 28, a louver 25, and a control unit 27. When the human presence sensor 28 determines that no one is present, the control unit 27 controls the louver 25 so that the air blown out from the air outlet 24 maintains a horizontal direction. When the human presence sensor 28 determines that a person is present, the control unit 27 controls the louver 25 so that the air blown out from the air outlet 24 is directed diagonally downward, and a portion of the air blown out from the air outlet 24 circulates to the air inlet 23. The circulating air may contain the aroma component generated from the aroma generating unit 26.

[0067] With this configuration, a pleasant scent such as aroma can be delivered only when the user is present. (Item 5) When the control unit 27 determines that a person is present using the human presence sensor 28, the air blown out from the air outlet 24 may be directed obliquely downward while partly maintaining a horizontal flow.

[0068] According to this configuration, it is possible to deliver a pleasant scent such as aroma to the user while maintaining the exhaust efficiency from the exhaust port 3.

[0069] Although the ventilation system according to the present disclosure has been described above based on the examples, the present disclosure is not limited to the examples. As long as it does not deviate from the spirit of the present disclosure, various modifications conceivable by a person skilled in the art to the examples and configurations constructed by combining components of different examples are also included within the scope of the present disclosure.
