Description

The present invention relates to a technique for an air purification greening device for greening and purifying air.

Conventionally, the technology of an air purification greening device for greening and purifying air has been known. For example, as described in Patent Document 1.

The air purification and greening device described in Patent Document 1 is provided on an inner housing having open front and back sides, a plant growth base (planting portion) provided on the front side of the inner housing, and a back side of the inner housing. It is provided with a fan (ventilation unit) provided, an irrigation pump (irrigation unit) capable of supplying water to the plant growth base, and a control device (control unit) for controlling the operation of the irrigation pump. The air purification and greening device operates a fan to suck air from the front side of the inner housing. The air is purified in the process of passing through the plant growth base, and is discharged from the back side of the inner housing to the outside of the air purification and greening device. The control device operates an irrigation pump according to the amount of air air passing through the plant growth base to irrigate the plant growth base. The water irrigated to the plant growth base in this way is appropriately drained to the outside of the inner housing.

In the air purification and greening apparatus described in Patent Document 1, the inside of the inner housing becomes negative pressure due to the operation of the fan. Since the control device of Patent Document 1 does not consider such a negative pressure in the inner housing, the irrigation pump may be operated while the fan is operating (in a state where the inner housing is in a negative pressure state). In this case, when the irrigated water is to be drained to the outside, a force for pulling the irrigated water into the water acts to make it difficult to drain the water.

Hereinafter, the air purification and greening device 10 according to the first embodiment of the present invention will be described.

The air purification greening device 10 is for greening and purifying air. The air purification and greening device 10 shown in FIG. 1 includes a main body portion 20, a housing 30, a planting portion 40, a rear fan 50, a water tray 60, a front fan 70, a control case 80, and the like.

The main body 20 is for storing the housing 30 and the like, which will be described later. The main body portion 20 is formed in a vertically long box shape by the front wall portion 21, the rear wall portion 22, the side wall portion 23, the top plate 24, and the like.

The housing 30 is for storing the planting unit 40. The housing 30 is formed in a vertically long box shape that can be stored in the main body 20. The housing 30 is formed so that the front portion and the rear portion are open so that air can pass through the front and rear portions. The housing 30 is fixed to the front upper end portion of the main body portion 20, and the planting portion 40 and the rear fan 50 described later are provided in the front and rear openings.

Such a housing 30 is arranged at a distance in front of the rear wall portion 22 of the main body portion 20. Further, the housing 30 is arranged at an upper interval with respect to the control case 80 described later. In this way, the main body 20 is formed with a ventilation space 25 partitioned by the housing 30, the control case 80, the rear wall 22, the side wall 23, and the top plate 24.

The planting section 40 is a portion where the plant P is planted. The planting section 40 is formed in a box shape. The planting portion 40 is fixed to the housing 30 by fastening the front end portion to the housing 30. In this way, the planting portion 40 is housed in the housing 30 except for the front end portion. A plurality of vent holes 40a are formed on the front side surface and the rear side surface of the planting portion 40 so that air can pass back and forth. Further, a plurality of through holes 40b are formed on the upper surface and the lower surface of the planting portion 40 so that water can pass from top to bottom. Such a planting section 40 is filled with soil S. The planting unit 40 includes a planter 41.

The planter 41 is for growing a plant P. The planter 41 is filled with soil and plant P is planted. The planter 41 is provided in the planting portion 40 so that the plant P faces forward and is exposed to the outside of the housing 30. A plurality of planters 41 (three in the first embodiment) are provided at intervals at the top and bottom.

The rear fan 50 sucks the air inside the housing 30 and discharges it to the outside of the housing 30 (ventilation space 25). The rear fan 50 is provided at the rear of the housing 30 (on the side opposite to the planting portion 40). The rear fan 50 is arranged at a distance from the planting portion 40 in the front-rear direction.

The water tray 60 is for receiving the water irrigated to the planting portion 40 and discharging it to the outside of the housing 30. The water tray 60 is formed in a concave shape recessed downward. The water pan 60 is formed so that the upper part and the front part are open. The water tray 60 is arranged so as to be inclined in the vertical direction with respect to the front-rear direction, and is configured to be able to guide water backward and downward. The water tray 60 is provided at the lower end of the housing 30 and is arranged below the planting portion 40. The water tray 60 includes a tubular portion 61.

The tubular portion 61 is arranged with the axial direction directed to the rear lower side (front upper side). The tubular portion 61 is formed so as to project downward from the rear side surface of the water tray 60. The tubular portion 61 is inserted into the rear lower end portion of the housing 30, and the inserted end portion opens in the ventilation space 25. The tubular portion 61 is connected to the tank 81 of the control case 80, which will be described later, via the drain hose 61a.

The water tray 60 configured in this way can receive water that is supplied to the planting section 40 and has fallen downward from the planting section 40. Further, the water tray 60 can guide the received water backward and downward and return it to the tank 81 via the tubular portion 61 and the drain hose 61a.

The front fan 70 is for sucking the air in the ventilation space 25 and discharging it to the outside of the main body 20. The front fan 70 is provided at the front end of the ventilation space 25.

The control case 80 houses the control unit 83 and the like, which will be described later. The control case 80 is provided at the lower part of the main body 20 (below the housing 30). The control case 80 includes a tank 81, a pump 82, and a control unit 83.

The tank 81 stores water for irrigating the planting unit 40.

The pump 82 is for sucking up the water in the tank 81 and supplying (irrigating) the water to the planting section 40. A water supply pipe 82a is connected to the pump 82. The water supply pipe 82a is arranged so that one end is connected to the pump 82 and the other end 82b extends to the upper end (above the planting portion 40) in the housing 30. The water supply pipe 82a is configured so that water can be discharged downward from the other end 82b. The water discharged from the water supply pipe 82a passes downward through the upper surface (through hole 40b) of the planting section 40 and is supplied to the planting section 40.

The control unit 83 is for controlling the operation of the equipment provided in the air purification and greening device 10. The control unit 83 is composed of, for example, a microcomputer or the like, and is configured to be capable of executing various processes related to the air purification and greening device 10. The control unit 83 is connected to the rear fan 50, the front fan 70, and the pump 82.

The control unit 83 can control the operation of the rear fan 50 by transmitting a signal to the rear fan 50. Specifically, the control unit 83 transmits a signal to the rear fan 50 to gradually change the rotation speed of the rear fan 50 (for example, "weak operation" with a low rotation speed and a medium rotation speed). It can be changed to a degree of "medium operation", a high rotation speed "strong operation", etc.), or the operation of the rear fan 50 can be stopped.

Further, the control unit 83 can control the operation of the front fan 70 by transmitting a signal to the front fan 70. Specifically, the control unit 83 can change the rotation speed of the front fan 70 stepwise or stop the operation of the front fan 70 by transmitting a signal to the front fan 70.

Further, the control unit 83 can control the operation of the pump 82 by transmitting a signal to the pump 82. Specifically, the control unit 83 can start the operation (start the operation) of the pump 82 or stop the operation of the pump 82 by transmitting a signal to the pump 82.

In the following, with reference to FIG. 2, the processing of the control unit 83 of the air purification and greening device 10 configured as described above will be described.

The control unit 83 operates the air purification and greening device 10 according to the flowchart shown in FIG. The control unit 83 executes steps S110 to S170 of the flowchart shown in FIG. 2 by appropriately executing the program.

First, in step S110, the control unit 83 operates the rear fan 50 and the front fan 70. When the process of step S110 is completed, the control unit 83 shifts to step S120.

In step S120, the control unit 83 determines whether or not accumulated points have been accumulated. The cumulative points are values for determining whether or not to operate the pump 82. In the first embodiment, the cumulative points are quantified (quantified) information on the amount of air aeration passing through the planting section 40. Accumulated points are appropriately calculated by adding points (added to the points up to that point) when a predetermined condition regarding the air volume is satisfied. Such predetermined conditions include, for example, the rotation speed and operating time of the rear fan 50.

Specifically, the control unit 83 is, for example, 1 point when the rear fan 50 moves for 1 minute in "strong operation" where the rotation speed is high, and in "weak operation" where the rotation speed is lower than "strong operation". If you move for 1 minute, 0.2 points will be added. When the points (total value of points) added in this way exceed a predetermined threshold value (for example, 1000 points), the control unit 83 determines that the accumulated points have been accumulated. For the predetermined threshold value, for example, a value at which the soil S of the planting portion 40 is presumed to be dry is appropriately set. The value of such a predetermined threshold value can be appropriately obtained by an experiment or the like. When the control unit 83 determines that the accumulated points have been accumulated (step S120: Yes), the control unit 83 proceeds to step S130. On the other hand, when the control unit 83 determines that the accumulated points have not been accumulated (step S120: No), the control unit 83 proceeds to step S110.

In step S130, the control unit 83 operates the pump 82. When the process of step S130 is completed, the control unit 83 shifts to step S140.

In step S140, the control unit 83 stops the operation of the rear fan 50 and the front fan 70. When the process of step S140 is completed, the control unit 83 shifts to step S150.

In step S150, the control unit 83 determines whether or not the pump 82 is operating for a predetermined time. The specified time is a preset operating time of the pump 82. For example, the operating time of the pump 82 required for irrigation of the planting unit 40 is set at the specified time. Such a specified time can be appropriately obtained by an experiment or the like. When the control unit 83 determines that the pump 82 is operating for a specified time (step S150: Yes), the control unit 83 shifts to the process of step S160. On the other hand, when the control unit 83 determines that the pump 82 has not been operated for a specified time (step S150: No), the control unit 83 shifts to the process of step S140.

In step S160, the control unit 83 stops the pump 82. When the process of step S160 is completed, the control unit 83 shifts to step S170.

In step S170, the control unit 83 determines whether or not a predetermined time has elapsed since the pump 82 was stopped. The predetermined time determines whether or not to operate the rear fan 50 and the front fan 70. For example, the time from when the pump 82 is stopped until the drainage from the water tray 60 is completed is set as the predetermined time. Such a predetermined time can be appropriately obtained by an experiment or the like. "20 minutes" is set as the predetermined time according to the first embodiment. This time of "20 minutes" is the time from when the pump 82 is stopped until the drainage from the water tray 60 is completed. When the control unit 83 determines that the predetermined time has elapsed (step S170: Yes), the control unit 83 resets the accumulated points and shifts to the process of step S110. On the other hand, when the control unit 83 determines that the predetermined time has not elapsed (step S170: No), the control unit 83 shifts to the process of step S160.

Hereinafter, the operation of the air purification and greening device 10 according to the steps S110 to S170 will be specifically described with reference to FIGS. 3 to 5. In addition, in FIGS. 3 to 5, the arrows shown by solid lines indicate the flow of air. The arrow indicated by the broken line indicates the flow of water.

As shown in FIG. 3, when the rear fan 50 and the front fan 70 are operated (step S110), air purification is performed. Specifically, the rear fan 50 sucks the air in the housing 30 by operating and discharges it to the ventilation space 25. In this way, the rear fan 50 generates a flow of air passing through the housing 30 from the front to the rear. The air passes through the planting section 40 from the front to the rear and is purified. The purified air flows into the ventilation space 25.

When the front fan 70 operates, it sucks the air (purified air) in the ventilation space 25 and discharges it to the outside (front) of the main body 20. As a result, the air purification and greening device 10 can purify the air. Further, the front fan 70 can supply (return) purified air to the same side (front side) as the side sucked by the rear fan 50.

In such an operation of the rear fan 50 and the front fan 70, the planting portion 40 is ventilated and gradually dried. Further, when the plant P absorbs the water contained in the soil S, the planting portion 40 is gradually dried. When the planting unit 40 is dried to the extent that irrigation is required in this way, cumulative points are accumulated (step S120: Yes), and the pump 82 is operated (step S130).

As shown in FIG. 4, when the pump 82 operates, the water in the tank 81 is sucked up, and water is supplied from the water supply pipe 82a (the other end 82b) to the planting portion 40. As a result, the planting portion 40 can be irrigated to prevent the plant P from dying. The water irrigated in this way falls downward from the planting portion 40 and is received by the water tray 60.

Here, when the rear fan 50 operates and sucks the air in the housing 30, the inside of the housing 30 becomes a negative pressure. When the inside of the housing 30 becomes negative pressure in this way, a force (see reference numeral F shown in FIG. 4) for drawing water from the outside to the inside (from the rear side to the front side of the cylinder portion 61) of the cylinder portion 61 is generated. If the water received by the water pan 60 is to be drained in such a state, the drainage may be hindered by the influence of the pulling force, and it may be difficult to drain the water from the water pan 60.

Therefore, as shown in FIG. 5, the control unit 83 stops the rear fan 50 and the front fan 70 after the operation of the pump 82 is started (step S140). According to this, since the negative pressure in the housing 30 can be eliminated, water can be drained from the water tray 60 without being affected by the pulling force. As a result, drainage can be performed smoothly, and it is possible to prevent water from accumulating (remaining) in the water pan 60. According to this, it is possible to prevent problems such as rusting of metal parts due to the influence of water collected in the water tray 60, rotting of water collected in the water tray 60, and propagation of various germs. ..

The pump 82 is stopped after a lapse of a predetermined time (step S150: Yes, step S160). The water irrigated to the planting section 40 gradually flows downward in the planting section 40. Therefore, the water tray 60 receives the water that has fallen from the planting unit 40 even after the pump 82 is stopped. Therefore, even if the operation of the pump 82 is stopped, drainage will continue. In the first embodiment, drainage is performed for 20 minutes (predetermined time) after the pump 82 is stopped.

In this way, when 20 minutes have passed since the pump 82 was stopped (step S170: Yes), the rear fan 50 and the front fan 70 are operated (step S110). According to this, since the negative pressure in the housing 30 can be eliminated until the drainage is completed, the drainage can be smoothly performed to the end. As a result, it is possible to effectively prevent water from accumulating in the water pan 60. Further, the rear fan 50 and the front fan 70 can be operated immediately after the drainage is completed. As a result, air purification can be resumed at the earliest possible stage.

As described above, the air purification and greening apparatus 10 according to the first embodiment includes a planting portion 40 in which the soil S is filled and the plant P is planted, a housing 30 in which the planting portion 40 is housed, and the housing. By sucking the air inside the body 30 and discharging it to the outside of the housing 30, the rear fan 50 (ventilation part) that allows the air to pass through the planting part 40 and the planting part 40 are irrigated. A pump 82 (irrigation section) to perform, a water tray 60 (drainage section) for draining water irrigated to the planting section 40, a control section 83 for controlling the operation of the rear fan 50 and the pump 82, and the like. The control unit 83 is provided with the first process (step S110) for operating the rear fan 50 with the first suction amount, and the control unit 83 is more than the first suction amount according to the operation of the pump 82. The second process (step S140) of controlling the rear fan 50 is performed so that the second suction amount is small.

With this configuration, the negative pressure inside the housing 30 can be relaxed by the second treatment, and drainage from the water tray 60 can be promoted. As a result, it is possible to prevent water from accumulating in the housing 30 and causing a problem.

Further, in the second process (step S140), the control unit 83 stops the rear fan 50 and sets the second suction amount to zero.

With such a configuration, the negative pressure in the housing 30 can be effectively relaxed, so that the water can be easily drained from the water tray 60.

Further, when the operation of the pump 82 is started (step S130), the control unit 83 starts the second process (step S140).

With this configuration, the second treatment can be performed at the timing when wastewater is required. As a result, it is possible to effectively prevent water from accumulating in the housing 30.

Further, the control unit 83 ends the second process according to the operation of the pump 82 (step S170: Yes, step S110).

With this configuration, it is possible to end the second treatment in consideration of the timing when the wastewater ends. As a result, the time for performing the second process can be shortened as much as possible.

Further, the control unit 83 ends the second process (step S170: Yes, step S110) when a predetermined time elapses after the operation of the pump 82 ends (the pump 82 stops). ..

With this configuration, the second process can be completed with a simple process.

The rear fan 50 according to the first embodiment is an embodiment of the ventilation portion according to the present invention.
Further, the pump 82 according to the first embodiment is an embodiment of the irrigation section according to the present invention.
Further, the water tray 60 according to the first embodiment is an embodiment of the drainage unit according to the present invention.

Hereinafter, the air purification and greening device 110 according to the second embodiment will be described.

In the following, the members configured in the same manner as the air purification and greening device 10 according to the first embodiment are designated by the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

The air purification and greening device 110 according to the second embodiment shown in FIG. 6 is provided with a plurality of units (three in the second embodiment) in which members (planting unit 132, etc.) for irrigation and air purification are grouped together. In that respect, it differs from the air purification and greening device 10 according to the first embodiment. In the following, this difference will be mainly described.

The air purification and greening device 110 according to the second embodiment includes a main body 20, a first unit 130, a second unit 140, a third unit 150, a front fan 70, and a control case 80.

The first unit 130 is a unit that irrigates and purifies air. The first unit 130 includes a housing 131, a planting section 132, a rear fan 133, a water pan 134, and a pump 135.

The housing 131, the planting unit 132, the rear fan 133, the water tray 134, and the pump 135 are the same as the housing 30, the planting unit 40, the rear fan 50, the water tray 60, and the pump 82 according to the first embodiment. It is composed of. The water tray 134 is connected to the tank 81 via a drain hose 134b connected to the tubular portion 134a. Further, the pump 135 supplies water to the planting portion 132 from above the housing 131 via the water supply pipe 135a. In FIG. 6, for convenience of explanation, only one planter 132a is described in the planting section 132, but in reality, as in the planter 41 of the first embodiment, there is a vertical interval. Three planters 132a are provided.

The second unit 140 is configured in the same manner as the first unit 130, except that it is provided below the first unit 130. Specifically, the housing 141 of the second unit 140, the planting unit 142, the rear fan 143, the water tray 144 and the pump 145 are the housing 131 of the first unit 130, the planting unit 132, and the rear fan 133. , Corresponds to the water pan 134 and the pump 135. Further, the planter 142a of the planting portion 142, the cylinder portion 144a and the drain hose 144b of the water tray 144, and the water supply pipe 145a of the pump 145 are the planter 132a of the planting portion 132 of the first unit 130 and the cylinder portion of the water tray 134. Corresponds to 134a, the drain hose 134b, and the water supply pipe 135a of the pump 135.

The third unit 150 is configured in the same manner as the first unit 130, except that it is provided below the second unit 140. Specifically, the housing 151 of the third unit 150, the planting unit 152, the rear fan 153, the water tray 154 and the pump 155 are the housing 131 of the first unit 130, the planting unit 132, and the rear fan 133. , Corresponds to the water pan 134 and the pump 135. Further, the planter 152a of the planting portion 152, the cylinder portion 154a and the drain hose 154b of the water tray 154, and the water supply pipe 155a of the pump 155 are the planter 132a of the planting portion 132 of the first unit 130 and the cylinder portion of the water tray 134. Corresponds to 134a, the drain hose 134b, and the water supply pipe 135a of the pump 135.

In addition, in FIG. 6, the pump 135, 145, 155, the drain hose 134b, 144b, 154b and the water supply pipe 135a, 145a, 155a are described as one, but in reality, the main body portion is individually described. It is provided in 20. Therefore, for example, when the pump 135 of the first unit 130 is operated, the planting section 132 is irrigated through the water supply pipe 135a, but the other planting sections 142 and 152 are not irrigated.

The control unit 183 of the control case 80 is connected to the rear fans 133, 143, 153 and the pumps 135, 145, 155 from the first unit 130 to the third unit 150. The control unit 183 can individually control the operations of the rear fan 133, 143, 153 and the pump 135, 145, 155. Further, the control unit 183 is connected to the front fan 70 and can control the operation of the front fan 70.

In the following, with reference to FIG. 7, the processing of the control unit 183 of the air purification and greening device 110 configured as described above will be described.

The flowchart shown in FIG. 7 shows the main processing (main flow) of the control unit 183. The control unit 183 operates the air purification and greening device 110 according to the flowchart shown in FIG. The control unit 183 executes steps S210 to S240 of the flowchart shown in FIG. 7 by appropriately executing the program.

First, in step S210, the control unit 183 operates the rear fans 133, 143, 153 and the front fans 70 of all the units 130, 140, and 150. When the process of step S210 is completed, the control unit 183 shifts to step S220.

In step S220, the control unit 183 determines whether or not accumulated points have been accumulated. The control unit 183 adds points according to the rotation speed and operating time of the rear fans 133, 143, 153, and determines that the accumulated points have been accumulated when the predetermined threshold value is exceeded. In the second embodiment, the control unit 183 does not calculate the cumulative points for each of the units 130, 140, and 150, but calculates the cumulative points for the entire units 130, 140, and 150, and determines the cumulative points. When the control unit 183 determines that the accumulated points have been accumulated (step S220: Yes), the control unit 183 proceeds to step S230. On the other hand, when the control unit 183 determines that the accumulated points have not been accumulated (step S220: No), the control unit 183 proceeds to step S210.

In step S230, the control unit 183 processes a subroutine that operates N pumps 135, 145, and 155 (total number of units, three in the second embodiment) by shifting them by a predetermined time. The processing of the subroutine will be described later. When the process of step S230 is completed, the control unit 183 shifts to step S240.

In step S240, the control unit 183 determines whether or not all of the N pumps 135, 145, 155 and the rear fans 133, 143, and 153 have been operated. At this time, the control unit 183 determines whether or not the pump has been operated by, for example, confirming the latest operation date and time from the transmission history (log) of the signal to the pump 135 or the like. When the control unit 183 determines that all the pumps 135 and the like have been operated (step S240: Yes), the control unit 183 resets the accumulated points and shifts to the process of step S210. On the other hand, when the control unit 183 determines that the pumps 135, 145, 155 and the rear fans 133, 143, 153 are all not operating (step S240: No), the process proceeds to the process of step S230.

Hereinafter, the processing of the subroutine in step S230 will be described with reference to FIG.

The processing of the subroutine is a process of irrigating in a predetermined order (in the second embodiment, the order of the first unit 130, the second unit 140, and the third unit 150). In the processing of the subroutine, the control unit 183 performs control corresponding to the control (steps S130 to S170) for the rear fan 50 and the pump 82 performed in the first embodiment, in the first unit 130, the second unit 140, and the third unit. This is done for the rear fans 133, 143, 153 and pumps 135, 145, 155 of the unit 150.

First, the control unit 183 controls the rear fan 133 and the pump 135 of the first unit 130 in steps S310 to S360.

Specifically, the control unit 183 stops the rear fan 133 (step S320) after operating the pump 135 of the first unit 130 (step S310), and is the pump 135 operating for a specified time? It is determined whether or not (step S330). Then, when the control unit 183 determines that the pump 135 has been operated for a specified time (step S330: Yes), the control unit 183 stops the pump 135 (step S340), and after the pump 135 is stopped, a predetermined time (20 minutes). Is determined (step S350). After that, when the control unit 183 determines that the predetermined time has elapsed (step S350: Yes), the control unit 183 operates the rear fan 133 (step S360). When the process of step S360 is completed, the control unit 183 shifts to step S370.

The control unit 183 controls the rear fan 143 and the pump 145 of the second unit 140 under the same control as the rear fan 133 and the pump 135 of the first unit 130 in steps S370 to S430 thus transitioned.

Then, when the process of step S430 is completed, the control unit 183 controls the rear fan 153 and the pump 155 of the third unit 150 with the same control as the rear fan 143 and the pump 145 of the first unit 130. In this way, the control unit 183 sequentially controls the rear fans and pumps of the N units.

According to such a main flow and a subroutine, the pumps 135, 145, and 155 of the first unit 130 to the third unit 150 can be operated and the rear fans 133, 143, and 153 can be stopped in order. As a result, it is possible to secure the air purification capacity while promoting drainage.

In the following, such promotion of drainage and purification of air will be described. In the following, the case where the rear fan 133 and the pump 135 of the first unit 130 are controlled will be described with reference to FIG. 9 as an example. Further, in FIG. 9, the arrow shown by the solid line indicates the flow of air. The arrow indicated by the broken line indicates the flow of water.

When the pump 135 of the first unit 130 is operated (step S310), the planting portion 132 of the first unit 130 is irrigated and water falls onto the water tray 134. When the water tray 134 drains the water that has fallen in this way, the rear fan 133 is stopped (steps S320 to S350), and the negative pressure in the housing 131 is eliminated. Therefore, the water tray 134 can smoothly drain the water that has fallen from the planting portion 132.

At this time, since the rear fans 143 and 153 are operating in the second unit 140 and the third unit 150, in the second unit 140 and the third unit 150, air is passed through the planting portions 142 and 152. Can purify the air.

When the second unit 140 is irrigated (the pump 145 is operated and the rear fan 143 is stopped) (steps S370 to S420), the rear fans 133 and 153 are operated in the first unit 130 and the third unit 150. The air is purified. Further, when the third unit 150 is irrigated, the rear fans 133 and 143 operate in the first unit 130 and the second unit 140 to purify the air.

As described above, in the control unit 183 according to the second embodiment, only one of the first unit 130 to the third unit 150 is irrigated, and the remaining two units continue to purify the air. (Step S230). As a result, even when the planting portions 132, 142, and 152 are irrigated, the air can be purified as much as possible. According to this, it is possible to secure the air purification ability while appropriately stopping the rear fans 133, 143, and 153 to promote drainage.

As described above, the air purification and greening device 110 according to the second embodiment includes the planting section 132, 142, 152, the housing 131, 141, 151, and the rear fan 133, 143, 153 (ventilation section). A plurality of the units 130, 140, and 150 are provided with the pump 135, 145, 155 (irrigation unit) and the water tray 134, 144, 154 (drainage unit) as one unit, and the control unit 183 is described. Among the plurality of units 130, 140, and 150, the second process is performed on some of the units, and the first process is performed on the units excluding some of the units (step S230). is there.

With this configuration, at least one unit can constantly perform the first process (running the rear fans 133, 143, 153). As a result, the air purification performance can be ensured.

Further, the control unit 183 performs the second process on each of the plurality of units 130, 140, and 150 in a predetermined order (step S230).

With this configuration, it is possible to sequentially perform the second process (process of stopping the rear fans 133, 143, and 153, steps S320 and S380) while performing the first process in as many units as possible. As a result, the air purification performance can be effectively ensured.

The rear fan 133, 143, and 153 according to the second embodiment is an embodiment of the ventilation portion according to the present invention.
Further, the pumps 135, 145, and 155 according to the second embodiment are one embodiment of the irrigation section according to the present invention.
Further, the water trays 134, 144, and 154 according to the second embodiment are one embodiment of the drainage portion according to the present invention.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above configuration, and various modifications can be made within the scope of the invention described in the claims.

For example, three planters 41, 132a, 142a, and 152a are provided in the planting sections 40, 132, 142, and 152 according to the first embodiment and the second embodiment, but the number of the planters 41, 132a, 142a, and 152a can be arbitrarily set. Can be set. Further, the planting portions 40, 132, 142, and 152 need only be provided with the plant P, and the planters 41, 132a, 142a, and 152a do not necessarily have to be provided.

Further, the air purification and greening devices 10 and 110 according to the first embodiment and the second embodiment do not necessarily have to include the main body 20 as long as the ventilation space 25 can be formed. In this case, for example, as in the air purification and greening device 210 according to the modified example shown in FIG. 10, a ventilation unit 290 can be provided instead of the main body unit 20. The ventilation portion 290 is a hollow member having a substantially L-shaped cross section. A ventilation space 25 is formed inside the ventilation portion 290. The ventilation unit 290 is placed on the control case 80. The housing 30 is placed on the ventilation portion 290.

Further, the air purification and greening devices 10 and 110 according to the first embodiment and the second embodiment do not necessarily have to include the front fan 70. In this case, the air purification and greening devices 10 and 110 may be configured to allow air from the rear fans 50, 133, 143, and 153 to pass rearward.

Further, the control units 83 and 183 according to the first embodiment and the second embodiment operate the pumps 82, 135, 145, and 155 based on the accumulated points, but the pumps 82, 135, 145, and 155 are operated. The criteria for whether or not to operate is not necessarily limited to cumulative points. The control units 83 and 183 may operate the pumps 82, 135, 145, and 155 based on a predetermined standard. The control unit 83/183 can use, for example, the water content of the soil S of the planting unit 40/132/142/152 as such a standard. In this case, the air purification and greening device 10/110 is provided with a moisture sensor for measuring the water content of the soil S, and the pumps 82, 135, 145, and 155 can be operated based on the measurement result of the moisture sensor. .. In this configuration, the control units 83 and 183 may operate the pumps 82, 135, 145, and 155 when the measurement result of the moisture sensor is less than a predetermined threshold value.

Further, the control units 83 and 183 according to the first embodiment and the second embodiment are supposed to operate the pumps 82, 135, 145 and 155 and then stop the rear fans 50, 133, 143 and 153. , The order in which the pumps 82, 135, 145, 155 are operated and the rear fans 50, 133, 143, 153 are stopped does not matter. Therefore, the control unit 83, 183 may, for example, stop the rear fans 50, 133, 143, 153 and then operate the pumps 82, 135, 145, 155, and the pumps 82, 135, 145, and so on. The operation of the 155 and the stop of the rear fans 50, 133, 143, and 153 may be performed at the same time.

Further, if the control units 83 and 183 according to the first embodiment and the second embodiment can reduce the pressure in the housings 30, 131, 141, and 151 when irrigating, they are not necessarily on the rear side. It is not necessary to stop the fans 50, 133, 143 and 153. In this case, the control units 83 and 183 may, for example, set the rotation speed of the rear fans 50, 133, 143, and 153 to be lower than those before irrigation (step S110, step S210).

Further, the control units 83 and 183 according to the first embodiment and the second embodiment operate the rear fans 50, 133, 143, and 153 after 20 minutes (predetermined time) have elapsed in steps S170 and S230. However, the predetermined time is not limited to 20 minutes, and may be any time.

Further, the trigger for operating the rear fans 50, 133, 143, and 153 (conditions in which steps S170, S350, and S420 are Yes) is not necessarily limited to the time elapsed since the pumps 82, 135, 145, and 155 were stopped. Other conditions may be used as triggers instead of being used. Such conditions include, for example, the operating time of the pumps 82, 135, 145, and 155, the amount of water accumulated in the water pans 60, 134, 144, and 154, and the like. When the rear fans 50, 133, 143, and 153 are operated with the amount of water, the air purification and greening device 10 and 110 are sensors that can confirm the amount of water (for example, water pans 60, 134, 144, and 154). A weight sensor or the like for measuring the weight of the rear fan 50, 133, 143, 153 may be operated based on the detection result of the sensor. In this configuration, the control unit 83/183 determines, for example, that no water remains in the water trays 60/134/144/154 (the weight is below a predetermined threshold value), and the rear fan 50 -133, 143, 153 may be operated.

Further, when the air purification and greening devices 10 and 110 are provided with such a sensor, the rear fans 50, 133, 143, and 153 may be stopped by using the detection result of the sensor as a trigger. Specifically, the control units 83 and 183 acquire the detection results of the sensor after operating the pumps 82, 135, 145, and 155, and based on the detection results, the water pans 60, 134, 144, and 154. Determine if water has begun to accumulate in the area. Then, the control units 83 and 183 stop the rear fans 50, 133, 143, and 153 when it is determined that water has begun to accumulate (the weight of the water trays 60, 134, 144, and 154 has increased). Even with such a configuration, the pressure in the housings 30, 131, 141, and 151 can be relaxed according to the operation of the pumps 82, 135, 145, and 155 to promote drainage.

Further, in the second embodiment, three units are provided, but the number of units is not limited to this, and may be any number.

Further, the control unit 183 according to the second embodiment irrigates the first unit 130, the second unit 140, and the third unit 150 in this order (stops the rear fans 133, 143, and 153). , The order of irrigation is not limited to this, and can be any order. In this configuration, for example, the control unit 183 may calculate the cumulative points for each unit and perform irrigation in order from the unit having the largest cumulative points (ventilation amount).

Further, the control unit 183 according to the second embodiment irrigates the first unit 130, the second unit 140, and the third unit 150 one by one, but the irrigation is controlled by all the units 130. It is not limited to this unless 140 and 150 are irrigated at the same time. The control unit 183 may control, for example, to irrigate two units at the same time.

Further, the control unit 183 according to the second embodiment may appropriately control the front fan 70. The control unit 183 may control the front fan 70 according to the operation of the rear fans 133, 143, and 153, for example. Specifically, the control unit 183 may lower the rotation speed of the front fan 70 when the rear fans 133, 143, and 153 are stopped (steps S320 and S380).
