Description

Pump control unit, pump device, and water supply device

The present invention relates to a pump control unit, a pump device, and a water supply device.

Conventionally, a cabinet-type pump device that can be installed outdoors is known as a pump device for supplying water to a building. In a cabinet-type pump device, a pump and a pump control unit that controls the pump are housed in a cabinet and protected from rain and wind. The cabinet is required to have durability and robustness so that the pump and the pump control unit can be protected. For example, the cabinet is formed in a box shape from a metal steel plate (see, for example, Patent Document 1).

A cabinet is generally composed of a cabinet body and a removable cover for assembly and maintenance. Further, in this case, for safety, the cabinet is designed with a key, for example, so that the cover is attached / detached by an engineer such as a maintenance worker and the cover is not attached / detached. In such cabinets, the cover is arranged with some clearance from them so as not to interfere with the pump and pump control unit in the cabinet. In particular, if the pump control unit in the cabinet is provided with an operation part with protrusions such as a toggle switch and push switch, the operation panel is designed to prevent the switches from being erroneously operated by opening / closing the cover or impacting the cabinet. The cover is arranged with a relatively large gap.

Further, conventionally, a pump device having a wireless communication function is known (see, for example, Patent Document 2). In this pump device, various command signals for operating the pump are received from an external device by wireless communication, or a signal related to the operation state of the pump is transmitted to the external device. Since information communicated wirelessly is information handled by the main board that controls the pump, generally, an electronic circuit for the wireless communication function is provided on the same board as the main board.

Furthermore, such a main board is generally formed of a printed circuit board. Electronic components are mounted on a printed circuit board, and the life tends to be shorter than that of a machine such as a pump. Also, in order to avoid sudden water outages due to failure, the board such as the main board is replaced at regular maintenance. Therefore, it is preferable that the printed circuit board of the pump device is detachably fixed to the pump device main body even after several years have passed after installation. Conventionally, a printed board such as a main board is not fixed with respect to the main body of the pump device, and a metal screw is used to prevent the screw head from being crushed at the time of replacement so that it is difficult to detach. It is fixed using (for example, refer patent document 3).

Patent Document 1: Japanese Patent No. 5208457 Patent Document 2: Japanese Patent Laid-Open No. 2005-171788 Patent Document 3: Japanese Patent Laid-Open No. 2008-166389

It is conceivable that the cabinet-type pump device has a wireless communication function so that a part of the pump device can be operated and information can be displayed using an external device without attaching or removing the cabinet cover. However, when an electronic circuit for a wireless communication function is provided in the cabinet, it is necessary to arrange the electronic circuit so that the wireless communication function is not hindered by the metal cabinet. On the other hand, if an electronic circuit for wireless communication is provided outside the cabinet, it is necessary to take measures for waterproofing the electronic circuit and wiring.

Also, if the electronic circuit for the wireless communication function is fixed to the pump device body with a metal screw or the like, the data communication may be hindered by the metal screw. Furthermore, in particular, in wireless communication using near field communication (NFC) technology, data communication cannot be secured if the distance between the external device and the electronic circuit for wireless communication is large.

[First Embodiment]
FIG.1 and FIG.2 is a figure which shows the water supply apparatus which concerns on 1st Embodiment of this invention from the front. Moreover, FIG. 3 is a figure which shows the inside of the water supply apparatus of 1st Embodiment from the left side. Here, FIG. 1 shows a state in which each device of the water supply device 1-1 is covered with the cover 1-102 of the cabinet 1-10, and FIG. 2 shows the water supply device with the cover 1-102 removed. Each device 1-1 is shown. In the following description, the front / rear / left / right direction means the front / rear / left / right direction of the water supply device 1-1.

The water supply device 1-1 includes a rectangular box-shaped cabinet 1-10 that integrally stores the devices described below. The cabinet 1-10 includes a base body (cabinet body) 1-100 and a cover 1-102 attached to the base body 1-100. The base body 1-100 and the cover 1-102 (cover body 1-103) are made of metal such as iron, steel, stainless steel, for example, so as to ensure the rigidity of the water supply device 1-1.

As shown in FIG. 1, the cover 1-102 is attached to the front surface of the base body 1-100, and houses each device of the water supply device 1-1 together with the base body 1-100. The cover 1-102 may be detachably attached to the base body 1-100 with a fixing tool such as a screw, or may be attached to the base body 1-100 so as to be openable / closable via a hinge or the like.

In the first embodiment, the fixture 1-107 and the boss 1-106 are further sealed by a sealing portion 1-109 such as silicon while being fastened to each other (see FIG. 5). For this reason, the plate portion 1-104 of the first embodiment has a portion that slightly protrudes toward the inside of the cabinet 1-10. However, the plate portion 1-104 of the cover 1-102 is not limited to the one having the window plate 1-108 attached to the back surface of the cover main body 1-103 and protruding inside the cabinet 1-10. . That is, the plate portion 1-104 may be formed by any method, for example, the window plate 1-108 is attached from the front surface of the cover main body 1-103. In the example shown in FIG. 5, the plate portion 1-104 has a slight step with respect to the front surface of the cover main body 1-103, but the front surface of the cover main body 1-103 is flush with the front surface. It may be formed.

Return the explanation to Figs. As shown in the figure, two vertical pumps 1-12a and 1-12b are arranged in parallel in the vertical direction inside the cabinet 1-10. The vertical pumps 1-12a and 1-12b are, for example, booster pumps each having a pump unit 1-14 and a motor unit 1-16. In each of the vertical pumps 1-12a and 1-12b, the pump unit 1-14 is driven by the power from the motor unit 1-16.

A suction header 1-18 extending in the horizontal direction is connected to the suction side of the vertical pumps 1-12a and 1-12b. The suction header 1-18 is connected to a suction pipe 1-22 equipped with a strainer-equipped ball valve 1-20 via a backflow prevention device 1-24. A pressure sensor 1-26 for detecting the pressure on the suction side is attached to the suction pipe 1-22. As a result, the main water pipe is connected to the strainer portion of the ball valve with strainer 1-20, and each of the vertical pumps 1-12a and 1-12b is operated with the ball valve 1-20 opened. Is sucked into the vertical pumps 1-12a and 1-12b via the suction pipe 1-22, the backflow prevention device 1-24, and the suction header 1-18.

On the other hand, a discharge elbow pipe 1-28 is connected to the discharge side of the vertical pumps 1-12a, 1-12b. The discharge elbow pipe 1-28 collects (combines) water discharged from the vertical pumps 1-12a and 1-12b via a discharge-side check valve 1-30 that prevents backflow of discharged water. A discharge collecting pipe 1-34 is connected. The discharge collecting pipe 1-34 has a flow switch 1-32 that detects a small amount of water and sends a signal (see FIG. 3). The discharge collecting pipe 1-34 is connected to the upper end of a bypass header 1-38 having a pressure sensor 1-36 for detecting the pressure on the discharge side. The bypass header 1-38 is connected to a pressure tank 1-40 via a pressure tank pipe 1-42 at a predetermined position, and is connected to a discharge pipe 1-46 having a ball valve 1-44 at the lower end. .

As a result, the water discharged from the vertical pumps 1-12a and 1-12b as the vertical pumps 1-12a and 1-12b are operated becomes the discharge elbow pipe 1-28 and the discharge check valve 1-30. Then, it is discharged from the discharge pipe 1-46 to the outside via the discharge collecting pipe 1-34 and the bypass header 1-38. When the water pressure in the suction header 1-18 is sufficiently high, the water in the suction header 1-18 is directly led to the discharge pipe 1-46 via a bypass pipe (not shown). It is discharged outside. The pressure tank 1-40 accumulates the pressurized water discharged from the vertical pumps 1-12a and 1-12b, thereby preventing frequent start and stop of the vertical pumps 1-12a and 1-12b and reducing the supply water pressure. It works to keep it smooth and constant.

An inverter device 1-54 is provided above the vertical pumps 1-12a and 1-12b. The inverter device 1-54 drives each motor unit 1-16 at a variable speed by supplying AC power to the motor units 1-16 of the vertical pumps 1-12a, 1-12b by changing the frequency and voltage. Is provided. The inverter device 1-54 is housed in an inverter case 1-56 supported by the cabinet 10. The inverter case 1-56 has a heat sink 1-52 made of, for example, aluminum and having heat radiating fins 1-50, and the inverter device 1-54 is placed on the upper surface of the heat sink 1-52 for storage.

In the upper part of the cabinet 1-10, the vertical pumps 1-12a, 1-12b receive signals from the pressure sensors 1-26, 1-36, etc., so that the feed water pressure at the end consumer becomes a predetermined pressure. Is provided with a control unit (pump control unit) 1-70 for variable speed operation. The control unit 1-70 is disposed vertically above the connection port of the suction pipe 1-22 and the connection port of the discharge pipe 1-46. In addition, the liquid flow paths of the vertical pumps 1-12a and 1-12b may be arranged vertically above the most vertically upper part. As a result, when the water supply device 1-1 is installed (when the main water pipe and the suction pipe 1-22 are connected, and when the water supply pipe and the discharge pipe 1-46 are connected to a water supply target such as a building) It is possible to prevent the control unit 1-70 from getting wet even if water leakage occurs due to a piping mistake. In the first embodiment, the control unit 1-70 is housed in the cabinet 1-10 separately from the inverter case 1-56 housing the inverter device 1-54. Thereby, maintenance and replacement of the inverter device 1-54 and the control unit 1-70 can be easily performed, and the influence of switching noise of the inverter device 1-54 is reduced in the control unit 1-70. be able to.

FIG. 6 is a diagram showing the control unit of the first embodiment. The control unit 1-70 is supported by a base body (cabinet body) 1-100 and has a unit case 1-72 that houses various components of the control unit 1-70. The unit case 1-72 accommodates, for example, a main board 1-73 for controlling the operation of the vertical pumps 1-12a and 1-12b to prevent the main board 1-73 from being wetted. As schematically shown in FIG. 5, the main board 1-73 is fixed to the unit case 1-72 using a metal screw 1-73a.

It has a second claw leg portion 1-776 and a second hooking portion 1-777 extending downward from the tip of the second claw leg portion 1-776. In the second claw leg portion 1-776, the inner (lower) leg side surface 1-776a can contact the side surface 1-79a of the wireless communication board 1-79. In the first embodiment, the front ends of the first hooking portion 1-773 and the second hooking portion 1-777 are convex portions that support the thickness t0 of the radio communication board 1-79 and the front surface of the radio communication board 1-79. It is configured to be positioned at a height that combines the height Hp of 1-779. Thus, in a state where the wireless communication board 1-79 is supported by the convex portion 1-779, the first hooking portion 1-773 and the second hooking portion 1-777 are connected to the rear surface ( The wireless communication board 1-79 is hooked around the hooked surface 1-79e). Here, the second hooking portion 1-777 extends along the hooked surface 1-79e over a length Lh2 larger than the length Lh1 of the first hooking portion 1-773 (FIG. 9). reference). Further, the distance Ls2 between the tip of the first hook portion 1-773 and the leg side surface 1-776a of the second claw leg portion 1-776 is equal to the side surfaces 1-79a and 1-79c of the wireless communication board 1-79. (Length in the vertical direction) L0 is formed (see FIGS. 10 and 11). On the other hand, the distance Ls1 between the tip of the second hooking portion 1-777 and the leg side surface 1-772a of the first claw leg portion 1-772 is equal to the side surfaces 1-79a and 1-79c of the wireless communication board 1-79. It is formed smaller than the length L0.

By such a guide portion 1-778, the wireless communication board 1-79 is supported while being limited in movement in the left-right direction, and the fixed position of the wireless communication board 1-79 can be made constant.

FIG. 12 is a diagram illustrating a method of fixing the wireless communication board by the fixing unit. As shown in the figure, when fixing the wireless communication board 1-79 to the panel board 1-77, first, the wireless communication board 1-79 is inclined and inserted into the inside (front side) of the second hooking portion 1-777. Then, the side surface 1-79a of the wireless communication board 1-79 is brought into contact with the leg side surface 1-776a of the second claw leg portion 1-776 (see the wireless communication board 1-79 indicated by a broken line in the figure). Next, the wireless communication board 1-79 is made parallel to the panel board 1-77 (see the wireless communication board 1-79 indicated by the solid line in the figure). As described above, the first hooking portion 1-773 of the first claw portion 1-771 has the distance Ls2 between the tip thereof and the leg side surface 1-776a of the second claw leg portion 1-776. It is formed larger than the length L0 of 79. Therefore, in a state where the side surface 1-79a of the wireless communication board 1-79 is in contact with the second claw leg portion 1-776, the side surface 1-79c of the wireless communication board 1-79 and the first hooking portion 1-79. The wireless communication board 1-79 can be made parallel to the panel board 1-77 without interference with 773. Then, by moving the wireless communication board 1-79 toward the first claw leg portion 1-772, the wireless communication board 1-79 is fixed to the panel plate 1-77 by the fixing portion 1-770 (FIG. 10). reference). As described above, the distance Ls1 between the tip of the second hooking portion 1-777 of the second claw portion 1-775 and the leg side surface 1-772a of the first claw leg portion 1-772 is equal to the wireless communication board 1-. It is formed smaller than the length L0 of 79. Therefore, in a state where the side surface 1-79c of the wireless communication board 1-79 is in contact with the leg side surface 1-772a of the first claw leg portion 1-772, the wireless communication board 1-79 is connected to the first hooking portion 1-77. The wireless communication board 1-79 cannot be detached from the panel board 1-77 by being hooked by the second hooking part 1-777. As described above, according to the configuration of the first embodiment, the wireless communication board 1-79 is mounted on the panel without deforming the wireless communication board 1-79, the first claw portion 1-771, and the second claw portion 1-775. It can be fixed to the plate 1-77.

When removing the wireless communication board 1-79 from the state fixed to the panel board 1-77, first, the wireless communication board 1-79 is moved to the second claw leg portion 1-776 side (indicated by a solid line in FIG. 12). (See Wireless Communication Board 1-79). As a result, the latching of the wireless communication board 1-79 by the first latching unit 1-773 is released. Next, the wireless communication board 1-79 is tilted backward so that the lower end of the wireless communication board 1-79 is positioned behind the first claw portion 1-771 (wireless communication board 1-shown by a broken line in FIG. 12). 79). Then, by fixing the wireless communication board 1-79 obliquely, the fixing of the wireless communication board 1-79 by the fixing unit 1-770 can be released. As described above, according to the configuration of the present embodiment, the wireless communication board 79, the first claw portion 1-771, and the second claw portion 1-775 can be wirelessly communicated from the panel board 1-77 without deformation. Board 1-79 can be removed.

Moreover, since the knob 1-81 is provided on the back of the wireless communication board 1-79 in this embodiment, the user holds the knob 1-81 to the panel board 1-77 with respect to the wireless communication board 1-77. -79 can be removed. In addition, since the fixed portion 1-770 is provided with guide portions 1-778 for supporting the movement of the wireless communication board 1-79 so as to be located on the left and right of the wireless communication board 1-79, the wireless communication board 1 The fixed position of −79 can be made constant.

As described above, since the wireless communication board 1-79 is fixed to the panel plate 1-77 by the fixing portion 1-770 formed of resin instead of being fixed by a metal screw or the like, the wireless communication board 1 By arranging a metal near -79, it is possible to avoid occurrence of a communication error due to interference or reflection of radio communication radio waves. In the first embodiment, the first claw portion 1-771 and the second claw portion 1-775 that hook the back surface (the hooked surface 1-79e) of the wireless communication board 1-79 as the fixing portion 1-770. Therefore, it is not necessary to make holes for fixing (for example, for resin screws) in the wireless communication board 1-79. For this reason, the antenna circuit 1-80 can be formed large on the front surface of the wireless communication board 1-79. Therefore, it is possible to improve the communication function by the wireless communication board 1-79, for example, the communication function such as extending the communication distance, expanding the communication range, and further suppressing the occurrence of a communication error.

Furthermore, in the first embodiment, the first claw portion 1-771 is disposed below the wireless communication board 1-79, and the wireless communication board 1-79 is separated from the first claw portion 1-771 by gravity. It is urged in a direction to contact the leg 1-772. For this reason, it is possible to prevent the wireless communication board 1-79 from being fixed unintentionally by the fixing unit 1-770.

The fixing of the wireless communication board 1-79 to the panel plate 1-77 is not limited to the examples shown in FIGS. For example, the wireless communication board 1-79 may be fixed to the panel plate 1-77 by a resin claw portion that is hooked to the wireless communication board 1-79 with deformation, or the panel plate is formed by a resin screw. It may be fixed to 1-77.

The water supply apparatus 1 may be fixedly installed on an outdoor wall surface of an apartment or building. In particular, in the examples shown in FIGS. 8 to 12, when the first claw portion 1-771 and / or the second claw portion 1-775 are deteriorated by ultraviolet rays due to outdoor use over time, the strength and elasticity are lowered. Therefore, it becomes difficult to attach and detach the wireless communication board 1-79. Therefore, by forming the window plate 1-108 with a material that blocks ultraviolet rays (for example, resin), it is possible to prevent the resin fixture from being deteriorated by the ultraviolet rays.

In this embodiment, the wireless communication board 1-79 is provided separately from the operation / display board 1-78, and the operation / display board 1-78 and the wireless communication board 1-79 are separated by a certain distance ( L1-L2) occurs (see FIG. 5). Therefore, even if the operation / display board 1-78 is fixed to the panel board 1-77 with the metal screw 1-78a, the wireless communication is not affected. Since the operation / display board 1-78 is tensioned when various buttons and the operation / stop switch 1-760b are operated, the operation / display board 1-78 is fixed to the panel plate 1-77 using a metal screw 1-78a. It is effective to prevent the fixing from being released.

Further, when the wireless communication board 1-79 and the operation / display board 1-78 are provided integrally, the integrally provided board is fixed to the panel plate 1-77 by a resin fixture, or Only a fixture that is close to the antenna circuit of the communication unit and is likely to interfere with wireless communication may be made of resin, and a metal screw may be used for the fixture near the operation unit. In other words, at least a wireless communication circuit area in which a wireless communication circuit (for example, an antenna circuit) for wireless communication is formed may be fixed to the panel board 1-77 by a resin fixture. For example, in the case of a slide switch such as the run / stop switch 1-760b, only a portion to which tension is applied during operation may be fixed with a metal screw, and the others may be fixed with resin. Further, the operation unit (E button 1-767, selection button 1-768, switching button 1-769, setting button 1-760a, operation / stop switch 1-760b, etc.) and the antenna circuit 80 of the wireless communication unit are connected. In the meantime, the display unit (display unit 1-761, operation / failure lamp 1-762, energy saving mode display lamp 1-763, operation state display lamp 1-764, abnormality display lamp 1-765, and operation mode selection lamp 1-766) may be arranged. With this arrangement, the distance between the operation unit and the antenna circuit 1-80 of the wireless communication unit is maintained, and metal screws can be used around the various buttons and the operation / stop switch 1-760b of the operation unit.

Return the explanation to FIG. As described above, the operation panel 1-76 of the first embodiment is provided with various buttons for various operations, the operation / stop switch 1-760b, and the like. These buttons and the operation / stop switch 1-760b prevent the unintentional operation from being performed by opening / closing the cover 1-102 of the cabinet 1-10 or external impact on the cabinet 1-10. It is preferable that they are arranged at a certain distance from 1-10. In particular, when the operation panel 1-76 includes a slide switch, a toggle switch or a lever switch such as the operation / stop switch 1-760b, the invalid operation is determined by software such as a program such as a push switch, It is difficult to forcibly change the state of the switch. Therefore, in the first embodiment, when the cover 1-102 is closed, the distance L1 between the operation / display board 1-78 of the operation panel 1-76 and the plate portion 1-104 of the cover 1-102. Are provided with a relatively large margin (for example, several centimeters). This can also prevent the protruding portion (such as the sealing portion 1-109) of the plate portion 1-104 from physically interfering with the control unit 1-70 (operation panel 1-76).

In addition, a breaker (not shown) for each pump is accommodated in the control unit 1-70, and a breaker switch is arranged so that the breaker can be operated on the same operation surface as the operation panel 1-76. May have been. If the breaker switch is accidentally turned off, the inverter, which is the pump drive source, is turned off and the pump cannot supply water. The distance L1 between the cover 1-102 and the plate portion 1-104 needs to be provided with a relatively large margin so that the breaker is not erroneously operated when the cover 1-102 is opened and closed.

On the other hand, as shown in FIG. 5, the wireless communication board 1-79 is disposed so as to be positioned in front of the apparatus as compared with the operation / display board 1-78. That is, the wireless communication board 1-79 is arranged such that the distance L2 between the cabinet 1-10 and the plate portion 1-104 is smaller than the distance L1 between the operation / display board 1-78 and the plate portion 1-104. (L2 <L1). As an example, in the first embodiment, the distance L2 between the wireless communication board 1-79 and the plate portion 1-104 is several millimeters (millimeters). In the present embodiment, the panel plate 1-77 of the operation panel 1-76 is formed so that the communication unit 1-790 is closer to the plate unit 1-104 of the cabinet 1-10 than the display unit 1-761 and the like. Has been. In other words, the panel plate 1-77 has a step 1 between a first support surface 1-77a that supports the operation / display board 1-78 and a second support surface 1-77b that supports the wireless communication board 1-79. 77c. In addition, the communication unit 1-790 (panel plate 1-77 and wireless communication board 1-79) of the operation panel 1-76 is parallel to the plate unit 1-104 when the cover 1-102 is closed. It is provided to become. In general, when the communication unit 1-790 uses NFC technology, the wireless communication board 1-79 is brought close to 10 cm (centimeter) or less in order to secure wireless communication in the communication unit 1-790. It is preferable to hold an external device. In the first embodiment, since the wireless communication board 1-79 is disposed near the plate portion 1-104 of the cabinet 1-10, the user can connect to the communication portion 1-790 via the plate portion 1-104. When the device is held over, wireless communication with the external device by the communication unit 1-790 can be performed more satisfactorily.

FIG. 13 is a diagram illustrating an example of a control unit and an external device. In FIG. 13, the control unit 1-70 is shown in a functional block diagram. As shown in the figure, the control unit 1-70 includes a storage unit 1-701 for storing data, a calculation unit 1-702 for calculating data, pressure sensors 1-26, 1-36, an inverter device 1-54, and the like. And an I / O unit 1-703 for exchanging data. Further, it has functions as a setting unit 1-704 for setting data, a display unit 1-705 for displaying data, and a communication unit 1-790 for wireless communication with the outside. The setting unit 1-704, the display unit 1-705, and the communication unit 1-790 are included in the operation panel 1-76 described above. The setting unit 1-704 shown in FIG. 13 includes a reset button 1-780 and a clear button 1-781, unlike FIG. By pressing the clear button 1-781, the control unit 1-70 clears the display on the operation panel 1-76. Further, when the reset button 1-780 is pressed, the control unit 1-70 causes the abnormality information (for example, abnormality information for the vertical pumps 1-12a and 1-12b) and maintenance information (for example, the operation time, the number of starts, the consumable parts). Data such as period of use and failure history).

As the external device 1-170, for example, a general-purpose terminal device such as a smartphone, a mobile phone, a personal computer, a tablet, or a dedicated terminal device such as a remote monitor is adopted. As the display unit 1-705, a simple indicator such as a 7-segment LED and an indicator lamp can be employed. Further, as the external device 1-170, a high-function display with a liquid crystal screen using a touch input method or a push button method can be employed. In this case, simple information can be displayed on the display unit 1-705, and a large amount of information can be displayed on the external device 1-170. With this configuration, the external device 1-170 displays information (for example, target pressure, current pressure, etc.) related to the control of the vertical pumps 1-12a, 1-12b by the control unit 1-70, so that the water supply device The user who is unfamiliar with can recognize the state of the water supply device 1-1 without misunderstanding.

For example, in the conventional water supply device 1-1, the display unit 1-705 of the operation panel 1-76 displays the discharge pressures of the vertical pumps 1-12a and 1-12b during normal operation, and the operation panel 1-76. According to the operation, the number of rotations, current, power, etc. for each pump are displayed. The number of rotations for each of these pumps was only checked by the maintenance staff at the time of periodic inspection or when a failure occurred. In the water supply device 1-1 of the present embodiment, for example, the water supply device 1 is used by using the external device 1-170. -1 information such as power consumption can be confirmed on a daily basis (for example, several times a day, several times a week, every few hours, etc.) in a trend graph. Therefore, the water supply device 1-1 can be managed by using the external device 1-170 without opening the cover 1-102, and the opening / closing of the cover 1-102 and the mechanical operation of the operation panel 1-76 are possible. These damages or deteriorations can be suppressed.

In addition, in the operation panel 1-76 of the water supply device 1-1, when a plurality of failures occur at the same time, the respective failure information is switched and displayed at regular intervals so that the user can grasp all the failures. There were cases where it was difficult. On the other hand, the water supply device 1-1 of the present embodiment can display a large amount of information on the external device 1-170, so that the user can be informed of the failure information accurately.

In addition, the water supply device 1-1 may be installed in an electrically noisy environment such as a machine room or a pump room.

The distance L1 between the cover 2-102 and the plate portion 2-104 needs to be provided with a relatively large margin so that the breaker is not erroneously operated when the cover 2-102 is opened and closed.

On the other hand, as shown in FIG. 25, the wireless communication board 2-79 is arranged so as to be positioned in front of the apparatus as compared with the operation / display board 2-78. That is, the wireless communication board 2-79 is arranged such that the distance L2 between the cabinet 2-10 and the plate portion 2-104 is smaller than the distance L1 between the operation / display board 2-78 and the plate portion 2-104. (L2 <L1). As an example, in this embodiment, the distance L2 between the wireless communication board 2-79 and the plate portion 2-104 is several millimeters (millimeters). In the present embodiment, the panel plate 2-77 of the operation panel 2-76 is formed so that the communication unit 2-790 is closer to the plate unit 2-104 of the cabinet 2-10 than the display unit 2-761 and the like. Has been. In other words, the panel plate 2-77 has a step 2 between a first support surface 2-77a that supports the operation / display board 2-78 and a second support surface 2-77b that supports the wireless communication board 2-79. 77c. The communication unit 2-790 (panel plate 2-77 and wireless communication board 2-79) of the operation panel 2-76 is parallel to the plate unit 2-104 when the cover 2-102 is closed. It is provided to become. Generally, when the communication unit 2-790 uses NFC technology, the wireless communication board 2-79 should be close to 10 cm (centimeter) or less in order to secure wireless communication in the communication unit 2-790. It is preferable to hold an external device. In this embodiment, since the wireless communication board 2-79 is disposed near the plate unit 2-104 of the cabinet 2-10, the user can connect the external device to the communication unit 2-790 via the plate unit 2-104. In this case, wireless communication with an external device by the communication unit 2-790 can be performed more satisfactorily.

FIG. 29 is a diagram illustrating an example of a control unit and an external device. In FIG. 29, the control unit 2-70 is shown in a functional block diagram.
