For this purpose, it is preferable that the air volume supplied from the backwash pipe 113c is set so as to exceed the air volume supplied from the diffuser pipe 113b.

  As described above, the septic tank 101 is a septic tank having both an aeration function and a backwashing function.

  For further details of the water treatment unit 110 described above, refer to, for example, a sewage septic tank disclosed in Japanese Patent Application Laid-Open No. 2000-5779.

  As shown in FIG. 2, the cover 6 of the pump 1 is configured to cover the upper surface of the housing 2. The cover 6 covers the upper surface of the housing 2, and has an annular wall portion 6 a extending along the outer periphery of the housing 2 and extending in the third direction Z, and the front end of the cover projects forward from the front surface of the housing 2. Projecting portion 7. The protrusion 7 has a function of preventing water droplets from being sucked together with air sucked from suction ports (suction ports 2b and 2b described later) provided on the upper surface of the housing 2. The protrusion 7 is set so that the length dimension in the second direction Y and the height dimension in the third direction Z are both effective dimensions for achieving this function.

  As shown in FIG. 3, the housing 2 accommodates an air compression unit 20 that sucks and compresses air. Further, the housing 5 accommodates a flow path switching unit 30 that can switch the flow path so that the air compressed by the air compression unit 20 is discharged from either one of the two discharge ports 5a and 5b. ing. The flow path switching unit 30 is disposed below the air compression unit 20 in the third direction Z. The air discharge unit 40 is constituted by the air compression unit 20 and the flow path switching unit 30.

  As shown in FIGS. 3 and 4, the housing 2 includes an annular standing wall 3 standing from the upper surface thereof. The standing wall 3 has a function of surrounding elements disposed in the upper part of the housing 2 (the concave accommodating space 3a). According to this standing wall 3, the intrusion of water into the accommodation space 3 a is suppressed. The elements here include a filter 9 and a controller 10. A filter 9 is disposed on the front side of the accommodation space 3a, and a controller 10 is disposed on the rear side of the accommodation space 3a.

  The cover 6 has a first position D1 (a position indicated by a solid line) which is a horizontal position around the hinge part (rotating shaft part) 6b of the housing 2 and a second position D2 which is an upright position standing substantially vertically (a position indicated by a solid line). (Position indicated by a two-dot chain line). Here, the first position D1 is a position where the standing wall 3 of the housing 2 is covered from above, and the second position D2 is a position where the covering is released.

  The cover 6 includes an engaging claw 6 c that can be engaged with an engaging convex portion 2 a provided on the front surface of the housing 2. The engaging claw 6c has flexibility. For this reason, when the cover 6 is set to the first position D1, the engagement claw 6c is bent from the initial position, gets over the engagement protrusion 2a and returns to the initial position, thereby engaging the engagement protrusion 2a. It is configured to be stopped.

  In the state where the cover 6 is set to the first position D1, the filter 9 and the controller 10 housed in the housing space 3a are both covered in a sealed manner. On the other hand, when the cover 6 is set to the second position D2, both the filter 9 and the controller 10 are exposed. For this reason, when the cover 6 is set at the first position D1, the standing wall 3 prevents water droplets from entering from the side surface of the housing 2 and entering the housing space 3a to affect the filter 9 and the controller 10. Can be prevented.

  Two suction ports 2b and 2b communicating with the air compression unit 20 are provided in the upper part of the housing 2 (in the accommodation space 3a). The housing 2 includes two notches 3b and 3b on the front side of the standing wall 3. These two notches 3b and 3b are for facilitating the suction of outside air into the accommodation space 3a in a state where the cover 6 is set at the first position D1.

  The filter 9 is interposed between the two notches 3b and 3b and the two suction ports 2b and 2b in the accommodation space 3a. The filter 9 has a function of preventing foreign matter and the like from being sucked together with outside air through the two suction ports 2b and 2b.

  The controller 10 is for controlling the pump 1. Although details will be described later, an operation panel 11 is provided on the upper surface of the controller 10.

  As shown in FIG. 5, the seal member 8 is attached to a region defined by the wall portion 6 a in the inner region of the cover 6. In order to clarify the seal member 8, the seal member 8 is hatched in this drawing. The seal member 8 is composed of a thin rubber sheet having elasticity. The seal member 8 includes an annular portion 8a that extends substantially annularly along the wall portion 6a, a first connection portion 8c, and a second connection portion 8d.

  The annular portion 8a is provided with two gaps 8b and 8b formed by partly dividing the annular portion 8a. Each of the two gaps 8b and 8b is provided at a position corresponding to each of the two notches 3b and 3b of the standing wall 3. For this reason, the flow path cross-sectional area of the air sucked through the two notches 3b and 3b of the housing 2 can be increased by the cross-sectional integral corresponding to the length in the third direction Z of the gap 8b. As a result, noise generated when air is inhaled can be reduced.

  The 1st connection part 8c is comprised so that it may extend in the 1st direction X and may connect the site | part which mutually opposes among the cyclic | annular parts 8a. The second connection portion 8d extends in the second direction Y and is configured to connect the annular portion 8a and the first connection portion 8c. By providing these connection portions 8c and 8d, the shape retaining property of the seal member 8 can be maintained at a desired level even if two gaps 8b and 8b are provided in the annular portion 8a. As a result, it is possible to prevent the ease of assembly of the seal member 8 with respect to the cover 6 from being deteriorated.

  As shown in FIG. 6, the seal member 8 is configured to seal between the cover 6 and the standing wall 3 of the housing 2 when the cover 6 is in the first position D1. Specifically, the seal member 8 is configured such that the annular portion 8 a contacts the upper end 3 c of the standing wall 3 of the housing 2. Further, the annular portion 8 a is configured to be pressed against the upper end 3 c of the standing wall 3 by a pressing piece 6 d provided on the cover 6. According to this configuration, the space between the accommodation space 3a and the external space is sealed by the annular portion 8a.

  In addition, when the cover 6 is not completely closed at the position before the first position D1, the water sealing performance by the seal member 8 is deteriorated. In this case, for example, there is a concern about the intrusion of water droplets along a route as indicated by an arrow in FIG. Therefore, the connecting surface that connects the side surface of the housing 2 and the outer peripheral surface of the standing wall 3 is configured as the inclined surface 4. The inclined surface 4 is an inclined surface that is inclined so that its height decreases from the outer peripheral surface of the standing wall 3 toward the side surface of the housing. In this case, it is preferable to keep the gap between the wall 6a of the cover 6 and the inclined surface 4 as small as possible.

  Accordingly, it is possible to make it difficult for water droplets to enter from the gap, and it is possible to eliminate the water droplets that try to stay in the gap by flowing down according to the inclined surface 4. Further, by providing the inclined surface 4 on the inner side of the side surface of the housing 2, when the pump 1 is viewed from above, the wall portion 6a of the cover 6 and the side surface of the housing 2 are substantially flush with each other, and the appearance is good. .

(Configuration and operation of controller 10)
As shown in FIG. 7, the operation panel 11 of the controller 10 is provided with an input unit 12 and a display unit 16. The input unit 12 includes three buttons 13, 14 and 15. When a button of the input unit 12 is pressed with a user's finger, a user instruction is input to the input unit 12. The display unit 16 is configured by a liquid crystal display. The contents designated by each button of the input unit 12 are displayed on the display unit 16.

  In addition to the display unit 16 described above, the controller 10 may be provided with an output means for outputting a sound instructed by each button of the input unit 12 or printing it out.

  The button 13 has a first function for switching between the automatic backwash mode and the manual backwash mode, and a second function for changing settings for the item selected by the button 14. As for the first function, when the automatic backwash mode is selected by the button 13, the backwash process is executed according to a preset program. Further, when the manual backwash mode is selected by the button 13, the backwash process condition can be set for an item to be selected and instructed by the button 14 thereafter.

  The button 14 is a button for switching items. Each time this button 14 is pressed, the position of the blinking cursor 16a on the display unit 16 is sequentially changed, and a desired item can be selected from a plurality of items (six in FIG. 7). For example, each time the button 14 is pressed, the current time (hour), current time (minute), program, backwash time (hour), number of backwashes (times / day), backwash time (minutes) The selection of switches. In FIG. 7, the cursor 16a in the unselected state is shown in black, and the blinking cursor 16a that is selected, that is, the cursor 16a corresponding to the program is shown in white.

  In a state where a desired item is selected by the button 14, the setting for the selected item can be changed by the second function of the button 13. For example, when the “program” item is selected by the button 14, the program number N corresponding to any one program P among the plurality of programs P is displayed on the display unit 16. Then, each time the button 13 is pressed thereafter, the program number N displayed on the display unit 16 changes sequentially.

  In each of the plurality of programs P, the number of backwashes (times / day) and the backwash time (minutes) are already set. Therefore, once the program number is set, the number of backwashes (times / day) and the backwash time (minutes) are uniquely determined. For this reason, after selecting the items of the number of times of backwashing (times / day) and the time of backwashing (minutes) by the operation of the button 14, the operation of setting the value of each item by the operation of the button 13 is unnecessary.

  On the other hand, in each of the plurality of programs P, the backwash time and the time interval until the next backwash are set in advance to a common initial value. In this embodiment, the initial value of the backwash start time for starting backwashing is preset at 2 o'clock, and the initial value of the time interval until the next backwashing is preset at 60 minutes. For this reason, the user can use these initial values as they are, or can appropriately change these initial values in accordance with the lifestyle or the like with the program number set.

  The button 15 is a button for resetting the setting contents set by the two buttons 13 and 14. When this button 15 is pressed, all of the already set contents are reset.

  As shown in FIG. 8, the controller 10 of the pump 1 has a built-in control unit 17 including a CPU (processing device) having a known configuration. The control unit 17 has a function of controlling the air discharge unit 40 in accordance with an instruction input to the input unit 12, and includes a storage unit 18 and a control signal output unit 19.

  The storage unit 18 has a function of storing a plurality of programs P that are individually determined for each of a plurality of different types of septic tanks 101 for the program P that is one of the above items. In this case, each program P is formed by combining a plurality of operation parameters of the air discharge unit 40. The storage unit 18 has a function of storing information selected and instructed by the two buttons 13 and 14. As a result, the program P selected and designated by the user from the plurality of programs P is stored in the storage unit 18.

  The control signal output unit 19 has a function of outputting a control signal to the air discharge unit 40 of the pump 1 in accordance with the program P selected and instructed by the user and stored in the storage unit 18. At this time, the control signal output unit 19 is configured to determine the output timing of the control signal to the air discharge unit 40 using a timer function (time measuring function) provided in the control unit 17.

  Therefore, when any one of the programs P stored in the storage unit 18 is instructed to be selected via the input unit 12 (two buttons 13 and 14), the program P is included in the program P. A control signal is output to the air discharge unit 40 based on the plurality of operating parameters. And the air discharge part 40 of the pump 1 operate | moves according to the program P instruct | indicated selection.

  Here, the program selection table will be described with reference to FIG. The user can set the program number of the item “program” via the input unit 12 of the controller 10 while referring to the selection table.

  This selection table includes "Manufacturer", "Model number", "Presence / absence of backwashing function", "Number of backwashing [times / day]", "Backwashing time [minute]", "Backwashing air volume [liter / minute] ], “Number of air diffusers stop [times / day]”, “Air diffuser stop time [minutes]”, “Air diffuser air flow [liters / minute]” items M1 to M9, program number N and information of each item Correspondence with is described.

  The item M1 describes the manufacturer of the septic tank, the item M2 describes the model number of the septic tank determined by the manufacturer, and the item M3 describes whether the septic tank has a backwash function. Moreover, the items M4 to M6 all describe the backwash operation conditions on the specifications of the septic tank. That is, the item M4 describes the number of times of backwashing per day, the item M5 describes the backwashing time per time, and the item M6 describes the amount of backwashing air per minute. Yes. Further, in each of the items M7 to M9, the aeration operation conditions on the specifications of the septic tank are described. That is, item M7 describes the number of air diffusers stopped per day, item M8 describes the air diffuser stop time per time, and item M9 describes the amount of air diffused per minute. Has been.

  In addition, since the value of the item M7 is substantially the same as the value of the item M4 about P1 to P4 of the program number N in FIG. 9, the description is omitted. Similarly, since the value of the item M8 is substantially the same as the value of the item M5, the description thereof is omitted.

  The user can set the program number N that matches the septic tank 101 that is the target of use of the pump 1 while viewing the information described in each item. As a result, the program P corresponding to the program number N is selected and instructed by the user.

Further, when the septic tank 101 is a septic tank corresponding to, for example, the model number T-002 of the manufacturer T or a septic tank corresponding to the model number U-001 of the manufacturer U, the program is based on the selection table of FIG. The number N is set to “P4”.

  Even if the “manufacturer” and “model number” of the septic tank 101 are not described in this selection table, if there is a program number N that matches the information in the items M3 to M9, the program number N is designated as the septic tank 101. Can be applied to.

  The program P is a program formed by combining a plurality of operation parameters C. In this case, the operation parameter C and the number thereof can be set as appropriate, and for example, any one of the four combination patterns shown in FIG. 10 can be adopted.

  In the first embodiment, the first pattern is adopted as a combination pattern of a plurality of operation parameters C. The first pattern is a pattern in which the program P includes two operation parameters C1 and C2. Both of the two operation parameters C1 and C2 are parameters relating to the flow path switching unit 30, that is, parameters for which operation conditions can be set by controlling the flow path switching unit 30.

  Specifically, one operating parameter C1 is the number of backwashing times per day [times / day], and the other operating parameter C2 is the backwashing time [minutes] per backwashing. In this case, the item M4 in FIG. 9 is the operation parameter C1, and the item M5 in FIG. 9 is the operation parameter C2.

  For the program P adopting the first pattern, for example, when the program number N of “P1” is selected and instructed by the user, the number of backwashing is set to 3 [times / day] and the backwashing time is 10 [minutes]. Set to When based on this program P, the flow path switching unit 30 is controlled by the controller 10 so that such a setting is realized. As a result, the first backwash start time is 2:00 (initial value), and the backwash end time is 2:10. Also, the start time of the second backwash is 3 o'clock, and the end time of the backwash is 3:10. Also, the start time of the third backwash is 4:00, and the end time of the backwash is 4:10.

  When the above start time is reached, the control signal output unit 19 causes the flow path switching unit 30 so that air is discharged only from the second discharge port 5b of the pump 1 and the air discharge is continued until the backwash time elapses. Output a control signal. On the other hand, at a timing other than backwashing, the control signal output unit 19 outputs a control signal to the flow path switching unit 30 so that air is discharged only from the first discharge port 5 a of the pump 1.

  In the first embodiment, another item can be set as the operation parameter C instead of or in addition to the items M4 and M5. As another item, for example, the amount of backwash per unit time, the backwash start time to start backwash, the backwash end time to end backwash, the time interval until the next backwash, etc. are adopted, and these Information can be added to the selection table of FIG. For example, when the time interval until the next backwash is used for the operation parameter C, the program is changed to 30 [minutes], 2 [hours], etc., relative to the initial value of 60 [minutes]. P can be used.

  The controller 10 preferably has a configuration in which the number of programs P can be added or deleted by appropriately rewriting the programs P stored in advance in the storage unit 18.

(Configuration and operation of air compressor 20)
As shown in FIG. 11, the case 21 of the air compressing unit 20 accommodates a pair of solenoids 22 and 22 as driving means. In the gap 22 a between the pair of solenoids 22, 22, the vibrator 23 is disposed so as not to contact the pair of solenoids 22, 22. The vibrator 23 includes permanent magnets (N pole and S pole) 23a and 23b having different polarities.

  Disc-shaped plate members 24 are attached to both ends of the vibrator 23. The plate member 24 is fixed to the case 21 via a disk-shaped diaphragm 24a. Therefore, the vibrator 23 is indirectly connected to the diaphragm 24 a via the plate member 24. The diaphragm 24a is formed of a rubber material that can be elastically deformed in order to perform an air suction operation and a discharge operation, and is configured to elastically deform following the reciprocating vibration of the plate member 24.

  The pair of solenoids 22 and 22 are arranged on the vibrator 23 so that the vibrator 23 reciprocally vibrates in the first direction X while elastically deforming the diaphragm 24a by electromagnetic force generated when power is supplied from an AC power supply (not shown). It fulfills the function of applying electromagnetic force.

  A valve case body 21 a is provided outside the plate member 24 in the case 21. The valve case body 21 a includes a compression chamber 25, a suction chamber 26 and a discharge chamber 28. The suction chamber 26 is a space for sucking air outside the pump as suction air from a suction port (not shown). The compression chamber 25 is a space for compressing the intake air sucked from the suction chamber 26 through the suction valve 27. The discharge chamber 28 is a space for discharging the compressed air compressed in the compression chamber 25 through the discharge valve 29.

  In the air compression unit 20 having the above configuration, when the vibrator 23 reciprocally vibrates in the first direction X in accordance with the polarity change when the pair of solenoids 22 and 22 are energized, each diaphragm 24a is displaced by the same displacement as the stroke of the vibrator 23. It is elastically deformed in the first direction X by the amount.

  When the diaphragm 24a on the right side is elastically deformed in the left direction during the stroke of the vibrator 23 in one direction (arrow X1), the right compression chamber 25 becomes negative pressure. This negative pressure closes the right discharge valve 29 and opens the right suction valve 27, so that air is sucked from the right suction chamber 26 into the right compression chamber 25 (suction operation).

  Further, when the left diaphragm 24a is elastically deformed leftward during the stroke of the vibrator 23 in one direction (arrow X1), air is pressurized in the left compression chamber 25. Due to this pressurization, the left suction valve 27 is closed and the left discharge valve 29 is opened, so that compressed air is discharged from the left compression chamber 25 to the left discharge chamber 28 (discharge operation). .

  On the other hand, as shown in FIG. 12, when the diaphragm 24a on the left side is elastically deformed in the right direction during the stroke of the vibrator 23 in the other direction (arrow X2), the compression chamber 25 on the left side becomes negative pressure. Become. Due to this negative pressure, the left discharge valve 29 is closed and the left suction valve 27 is opened, so that air is sucked into the left compression chamber 25 from the left suction chamber 26 (suction operation).

  Further, when the right diaphragm 24a is elastically deformed rightward during the stroke of the vibrator 23 in the other direction (arrow X2), air is pressurized in the right compression chamber 25. This pressurization closes the right suction valve 27 and opens the right discharge valve 29, so that compressed air is discharged from the right compression chamber 25 to the right discharge chamber 28 (discharge operation). .

  By alternately repeating the suction operation and the discharge operation as described above, the compressed air having a predetermined pressure and flow rate is continuously discharged from the air compression unit 20 toward the flow path switching unit 30 in the housing 5. At this time, the amount of air discharged from the air compressor 20 can be changed by changing the stroke amount of the vibrator 23 or the number of strokes per unit time under the control of the AC power supply.

(Configuration and operation of flow path switching unit 30)
As shown in FIG. 13, the housing 5 includes an inflow chamber 5 c into which compressed air flows from the discharge chamber 28 of the air compression unit 20, and compressed air from the inflow chamber 5 c to each of the two discharge ports 5 a and 5 b. It has two flow paths R1, R2 for flowing. The first flow path R1 is a flow path extending from the inflow chamber 5c to the first discharge port 5a. According to the first flow path R1, the compressed air flowing into the inflow chamber 5c is discharged from the first discharge port 5a. On the other hand, the second flow path R2 is a flow path extending from the inflow chamber 5c to the second discharge port 5b. According to the second flow path R2, the compressed air flowing into the inflow chamber 5c is discharged from the second discharge port 5b.

  The flow path switching unit 30 can form a communication state in which the inflow chamber 5c is connected to the first discharge port 5a through the first flow path R1 by the linear flow path switching operation, or the inflow chamber 5c is in the second flow direction. A communication state in which the second discharge port 5b is connected through the path R2 can be formed. In order to achieve this flow path switching operation, the flow path switching unit 30 includes a first valve seat 31 and a second valve seat 32 each attached to the housing 5, a rod 33, and a switching fixed to the rod 33. A valve 34, a spring member 35, and a solenoid 36 are provided.

  The first valve seat 31 includes a communication hole 31a for connecting the inflow chamber 5c to the first flow path R1. The second valve seat 32 includes a communication hole 32a for connecting the inflow chamber 5c to the second flow path R2. The communication hole 31a and the communication hole 32a are arranged on an imaginary straight line extending in the first direction X.

The rod 33 is a long shaft-like member, and is inserted into both the communication hole 31 a of the first valve seat 31 and the communication hole 32 a of the second valve seat 32, and the one end 33 a is one end of the spring member 35. The other end 33 b is connected to one end of the movable iron core 38 of the solenoid 36.

  The switching valve 34 performs a function of performing a flow path switching operation for compressed air by linear motion so that the inflow chamber 5c communicates with one of the two flow paths R1 and R2. In order to achieve this function, the switching valve 34 is disposed between the first valve seat 31 and the second valve seat 32 while being fixed to the rod 33. When the rod 33 reciprocates in the first direction X, the switching valve 34 closes and seals either the communication hole 31a of the first valve seat 31 or the communication hole 32a of the second valve seat 32. It is configured as. For this reason, the compressed gas that has flowed into the inflow chamber 5c from the air compression unit 20 flows into one of the two flow paths R1 and R2 by the flow path switching operation of the switching valve 34.

  The spring member 35 and the solenoid 36 have a function as an actuator for causing the rod 33 to reciprocate integrally with the switching valve 34.

  The spring member 35 is a so-called “tensile coil spring”, and the other end opposite to the rod 33 is fixed to the fixing pin 5 d of the housing 5. For this reason, the rod 33 is always elastically biased by the spring member 35 in a direction approaching the fixed pin 5d.

  The solenoid 36 is a solenoid actuator that operates when power is supplied from an AC power supply (not shown) and causes the switching valve 34 to switch the flow path by electromagnetic force, and converts electrical energy into linear mechanical motion. It is configured as a direct acting solenoid (electromagnet). The solenoid 36 includes a coil (not shown) wound with a copper wire, a fixed iron core 37 fixed to the housing 5, and a movable iron core 38 operable linearly in the first direction X with respect to the fixed iron core 37. And.

  The fixed iron core 37 has a resin mold structure in which a laminate of a plurality of metal plates made of a magnetic material such as iron is molded with a resin. The fixed iron core 37 includes a space 37a extending in the first direction X inside. The movable iron core 38 is made of a magnetic material such as iron like the fixed iron core 37. The movable iron core 38 is inserted into the space 37 a of the fixed iron core 37.

  In the solenoid 36 having the above-described configuration, a magnetic field is generated in the central portion of the coil by supplying power from the AC power source. At this time, the magnetized fixed iron core 37 attracts the movable iron core 38, whereby the solenoid 36 operates. The movable iron core 38 is sucked in the direction in which it is inserted into the space 37 a of the fixed iron core 37 when the solenoid 36 is operated.

  Therefore, the movable iron core 38 is attracted to the fixed iron core 37 by overcoming the elastic biasing force of the spring member 35 when the solenoid 36 is operated. Thereby, the rod 33 moves in the direction approaching the solenoid 36 in the first direction X, and the communication hole 32a of the second valve seat 32 is sealed by the switching valve 34 (see FIG. 14). As a result, the compressed air flowing into the inflow chamber 5c is blocked from flowing into the second flow path R2, and is discharged from the first discharge port 5a through only the first flow path R1.

  On the other hand, the solenoid 36 is deactivated when the power supply from the AC power supply is temporarily stopped. Therefore, the movable iron core 38 is pulled in the direction in which it is inserted from the space 37 a of the fixed iron core 37 according to only the elastic biasing force of the spring member 35 when the solenoid 36 is not operated. Thereby, the rod 33 moves in the direction away from the solenoid 36 in the first direction X, and the communication hole 31a of the first valve seat 31 is sealed by the switching valve 34 (see FIG. 15). As a result, the compressed air flowing into the inflow chamber 5c is prevented from flowing into the first flow path R1, and is discharged from the second discharge port 5b only through the second flow path R2.

  Next, the function and effect of the first embodiment will be described.

  When the septic tank 101 to be used is determined when the pump 1 is newly installed or replaced, the user. A program number N corresponding to the septic tank 101 is set while looking at the program selection table of FIG. At this time, the user only selects and instructs one of the plurality of programs P via the input unit 12, and the two operation parameters C <b> 1 and C <b> 2 included in the program P are stored in the septic tank 101. It is possible to set the operating conditions suitable for. That is, the setting operation of the two operation parameters C1 and C2 of the pump 1 can be performed at once from the input unit 12. And the air discharge part 40 is controlled according to the driving | running condition set about two driving | operation parameter C1, C2.

  According to such a setting operation, the time required for the setting operation can be shortened compared to the case where the setting operation is performed individually for each of the two operation parameters C1 and C2. Therefore, the setting effort can be reduced. As a result, the user can easily perform an operation for setting the operating condition of the pump 1.

  Further, by storing the program P corresponding to each of a plurality of different types of septic tanks in the storage unit 18, one pump 1 can be applied to any of the plurality of septic tanks. Can be increased. Of course, the pump 1 can be applied to another septic tank of the same type.

  In addition, for the septic tank 101 having both a diffuser function and a backwash function, as a plurality of operation parameters included in each program P, the number of backwashes per day, the backwash time per backwash time, It becomes possible to control the air pump using.

In the pump 1, the cover 6 has a function of preventing water droplets from entering a region of the housing 2 surrounded by the standing wall 3. When the cover 6 is in the first position D1, the input unit 12 and the control unit 17 surrounded by the standing wall 3 are covered by the cover 6 and sealed by the seal member 8. For this reason, the preventiveness about the input part 12 and the control part 17 of the pump 1 can be improved.
Further, when the cover 6 is in the second position D2, the input unit 12 can be operated. According to this rotatable cover 6, the input unit 12 can be easily set to an operable state. For this reason, the operativity of the input part 12 of a pump improves.

And the amount of backwash air is set to 100 [liters / minute]. When based on this program P, the air compression unit 20 and the flow path switching unit 30 are controlled by the controller 10 so that such a setting is realized. As a result, the backwash start time is only 2 o'clock (initial value), the backwash end time is 2:10, and the backwash air volume is 100 [liter / min].

  At the above start time, the control signal output unit 19 causes the flow path switching unit 30 so that air is discharged only from the second discharge port 5b of the pump 1a and the air discharge is continued until the backwash time elapses. The control signal output unit 19 outputs a control signal to the air compression unit 20 so that the backwash air volume at that time becomes the set air volume. On the other hand, at a timing other than backwashing, the control signal output unit 19 outputs a control signal to the flow path switching unit 30 so that air is discharged only from the first discharge port 5a of the pump 1a.
