DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An air pump and a remote setting device according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a schematic diagram of the air pump in FIG. 1, and FIG. 3 is an explanatory diagram showing a switching mode.

As shown in FIGS. 1 and 2, the air pump includes a two-way solenoid valve 4 for switching between an air discharge channel 2 and a discharge channel 3 in a pump body 1, and a controller for controlling the switching of the electromagnetic valve 4. 5 and a jack 7 for detachably connecting a cable 6 to the controller 5.

In the present invention, the pump body 1 is
Without being limited, a normal air pump, for example, based on the magnetic interaction between an electromagnet and a permanent magnet, driven by a diaphragm coupled to the vibrator by electromagnetic vibration of the vibrator with the permanent magnet, For example, a vibrating pump that sucks air and discharges the air can be used.

The controller 5 stores an external input and turns on / off the power supply of the solenoid valve 4 according to a program of a predetermined procedure.
A bit microcomputer can be used.

The air tank 8 in the pump body 1 has:
A first discharge passage 9 to which the solenoid valve 4 is connected in the middle
And the second discharge channel 10 are connected. The air discharged from the air tank 8 in the pump body 1 is continuously discharged to the first and second discharge channels 9 and 10 (see FIG. 3A), while the controller 5 When the valve 4 is turned off, the liquid is discharged from the first discharge flow path 9 to the discharge flow path 2 side (FIG. 3).
(See (c)), but the solenoid valve 4 is turned on by the controller 5.
The discharge direction is the same as the discharge flow path 3
Side (see FIG. 3B).

When the air pump of the present embodiment is used in a purification tank of a purification device as shown in FIG. 4, the discharge flow path 2 from the first discharge flow path 9 is connected to an air lift adjustment air flow path, The discharge passage 3 is connected to the backwash air passage, and the second discharge passage 10 is connected to the backing air passage. In such a case, it is preferable to connect a valve 11 for adjusting the discharge amount of air in the middle of the discharge passage 2.

The input to the controller 5 for turning on and off the power of the solenoid valve 4 in the air pump is as follows:
This is performed by the remote setting device 20.

As shown in FIGS. 1 and 3, the remote setting device 20 includes a selection unit A for selecting a current time.
And a mode selector B for selecting a time in the air pump and a switching time T and a time t of the air pump.

In the present embodiment, the cable 6 is detachably connected to a control unit in the setting device main body 21, for example, a jack 22 of an internal input / output cable drawn from a 4-bit microcomputer. However, the present invention is not limited to this, and the cable 6 and the internal input / output cable may be integrally connected.

On the front panel 23 of the setting device body 21, switches for the selection section A, mode selection section B, adjustment section D and setting section E are provided.
A liquid crystal display 24 of the display section C is provided. When each of the switches is used in a purifying device, the current time switch 25, the pump time selection switch 26, the backwash time selection switch 27, the backwash time selection switch 28, the hour UP switch 29a, the hour DOWN switch 29b, and the minute UP A switch 30a, a minute DOWN switch 31b, and a setting switch 31.

Next, the switching time of the controller in the air pump and the setting of the backwashing time and the backwashing time, which are the switching times, using the remote setting device will be described.

First, the power of the setting device main body 21 is turned on, and the current time selection switch 25 is pressed. And when UP, DOWN
After using the switches 29a and 29b and the minute UP and DOWN switches 30a and 30b to adjust the display on the liquid crystal display 24 to the current time, the setting switch 31 is pressed. As a result, the current time is stored in the setting device main body 21.

Next, the cable 6 is connected to the controller 5 of the air pump. Then, in order to know the current time in the pump, the user presses the time switch 26 in the pump. Next, the user presses the current time selection switch 25 that has been adjusted, and if the in-pump time displayed on the liquid crystal display 24 does not match the current time, the hour UP, DOWN switches 29a, 29b and the minute UP, DOWN Switch 30
Set the current time using a and 30b. Thereafter, the user pushes the setting switch 31 to cause the controller 5 to store the current time.

Next, in order to set the backwash time setting mode,
Press the backwash time selection switch 27. And when UP, D
DOWN switches 29a, 29b and minute UP, DOWN
The switches 30a and 30b are used to set a predetermined backwash time. Thereafter, the setting switch 31 is pressed to cause the controller 5 to store the backwash time.

Next, in order to enter the backwashing time setting mode, the backwashing time selection switch 28 is pressed. And when UP, DOW
Use the N switches 29a and 29b and the minute UP and DOWN switches 30a and 30b to adjust to a predetermined backwashing time.
Thereafter, the setting switch 31 is pressed to cause the controller 5 to store the backwash time.

With the above operation, the cable 6 is disconnected from the air pump for which the setting of the backwash time and the backwash time has been completed. The same setting operation is performed for the air pumps of the other purifying devices.

According to the remote setting device of the present invention, the above-described setting operation can be performed to appropriately change the backwash time and the backwash time, and the backwash time and the backwash time of the air pump in each purifying device can be set. It can be easily changed according to the type of sewage.

In the above description, the pump body 1
The transmission and reception of various signals between the controller 5 and the setting device main body 21 are performed by the cable 6,
In the present invention, the present invention is not limited to this. That is, a transmitter / receiver may be provided instead of the jack of the air pump, and a transmitter / receiver may also be provided in the remote setting device so that signals can be transmitted and received between each other by ordinary wireless communication or wireless communication such as optical signal. As the wireless signal, for example, an optical system such as infrared rays or an electromagnetic wave can be used.

[0029]

As described above, according to the present invention,
Since the controller and the setting device of the air pump are separated, the price of the air pump itself can be reduced.

Further, since the controller and the remote setting device can be connected by a cable or by wireless communication, for example, the controller of the air pump in a plurality of purification devices can be switched to the switching mode by one remote setting device. Can be set to Further, the switching mode can be appropriately changed as needed.
