  The control panel described above has the following problems. That is, the control panel and the pump device are required to save space, that is, to reduce the space inside the control panel, because of the demand for reduction in installation area and size reduction. However, if the electrical components in the control panel are arranged close to each other, the life of the electrical components is reduced due to the influence of heat generated by the electrical components.

  Also, if each electrical component in the control panel is placed close to each other to reduce the size of the control panel, the connection wiring of each electrical component will be close to each other. In addition, there is a risk of adversely affecting the connection wiring in the replacement work of the failed electrical component.

Such problems of the prior art will be described with reference to FIGS.
As shown in the left diagram in FIG. 13, the connection wiring 201 is fixed to the electrical component 200 provided in the control panel by a fastening member B such as a bolt. In the replacement operation of the failed electric component 200, when the electric component 200 is removed from the control panel mounting plate 202, the fastening of the connection wiring 201 by the fastening member B is released, and the connection wiring 201 is removed from the electric component 200.

  Such an electrical component 210 may be replaced with a new electrical function unit 211 even if the electrical function unit 211 breaks down, has high maintainability, and can reduce running costs. Further, since the electrical component 210 can fix the terminal portion (socket terminal block) 212 to the mounting plate 202 and the electrical function portion 211 can be exchanged in a state where the connection wiring 201 is connected to the terminal portion 212, Damage can be prevented.

  However, the electrical component 210 that can separate the electrical functional unit 211 and the terminal unit 212 is expensive, and is larger than the electrical component that cannot be separated. Become.

  In addition, in the inverter, the earth leakage breaker, the magnetic contactor, and the like, which are the main components of the control panel, there are few that can be separated from the terminal unit 212 by the electrical function unit 211.

  The attachment means 13 includes a plurality of attachment members 41 that fix the inverter 31 to the back plate 23, and a fastening member that fixes the electrical component 12 other than the inverter 31 to the back plate 23. The attachment member 41 is provided along the back plate 23 and has a heat exhaust plate 43 having an opening 43a facing the heat generating portion 37 of the inverter 31 and the back plate 23, and also fixes the heat generating portion 37 of the inverter 31. A pair of suspension members 44. The heat exhaust plate 43 and the suspension member 44 are integrally formed of a metal material.

  The suspension member 44 is provided at both side ends of the heat exhaust plate 43. The suspension member 44 is fixed to both side surfaces of the heat generating portion 37 by fitting or fastening with a fastening member. The suspending member 44 is provided with a protruding portion 45 on the upper and lower end sides thereof and on a portion (front surface) facing the back plate 23. The protrusion 45 has a groove 46 extending in the direction of gravity at the ridge between the lower surface thereof and the front surface of the suspension member 44.

  As shown in FIGS. 10 and 11, the first attached portion 25 </ b> A of the back plate 23 to which the attachment member 41 is attached includes a cutout portion 51 through which the protruding portion 45 provided on the upper end side of the suspension member 44 is inserted.

That is, the first attached portion 25 </ b> A is an opening formed in the back plate 23. The notch 51 is formed to have the same width as the protrusion 45 or slightly wider than the protrusion 45.

  Further, the thickness of the lower end portion of the cutout portion 51 of the back plate 23 and the lower end portion of the opening portion 52 is formed substantially the same as the width of the groove portion 46. The notch 51 and the opening 52 are, after the protrusion 45 is inserted, the groove 46 of the upper protrusion 45 and the lower end of the notch 51, and the groove 46 of the lower protrusion 45 and the lower end of the opening 52. However, each is formed so that fitting is possible. That is, the notch 51 and the opening 52 are fitting portions that fit into the protrusion 45.

  When the notch 51 is positioned on the cover 26 provided on the back plate 23, the notch 51 is provided across both the back plate 23 and the cover 26. Moreover, the groove part 46 should just be formed substantially the same as the thickness of the lower end part of the notch part 51 formed in the back plate 23 and the cover 26.

  In the pump device 100 configured in this manner, the inverters 31 of the plurality of electrical components 12 of the control panel 1 can be fixed to the back plate 23 from the back side of the housing 10 by the mounting member 41. Hereinafter, attachment of the inverter 31, which is one of the electrical components 12, will be described.

  First, the side surface of the heat generating portion 37 of the inverter 31 is fixed to the pair of hanging members 44. Next, as shown in FIGS. 4 to 9 and 12, the protrusions 45 and 45 of the suspension member 44 to which the inverter 31 is fixed are inserted into the corresponding cutouts 51 and openings 52.

  With the protrusions 45 and 45 inserted into the notch 51 and the opening 52, the inverter 31 is moved in the direction of gravity, and the groove 46 and the notch 51 and the lower end of the opening 52 are fitted. By this fitting, the inverter 31 is fixed to the back plate 23.

  At this time, a rotation moment about the groove 46 is applied to the heavy side in the front-rear direction of the inverter 31, and the rotation moment causes the inner surface of the groove 46 and / or the front surface of the suspension member 44 and the outer surface of the back plate 23 to mutually. Abut.

  In this way, by suspending the pair of suspension members 44 to which the inverter 31 is fixed on the back plate 23, the back plate 23 is caused by the force in the gravity direction due to the weight of the inverter 31 and the rotational moment about the groove 46. The attachment member 41 is fixed to the rear plate 23, and the inverter 31 is fixed to the back plate 23. Thus, the attachment member 41 to which the inverter 31 is fixed is attached to the back plate 23 in the direction of gravity, the surface direction of the back plate 23, and the direction orthogonal to the gravity direction and the surface direction of the back plate 23 (with respect to the back plate 23. Are fixed in three axial directions.

  After fixing the inverter 31 to the back plate 23 through the mounting member 41 in this way, the inverter 31 and the connection wiring 36 are connected as shown in FIG.

  According to the pump device 100 configured as described above, the control panel 1 can attach the electrical component 12 from the back side of the housing 10, and thus the electrical component 12 can be easily attached and detached. Specifically, when the electrical component 12 is viewed from the front side of the control panel 1, the connection wiring 36 is disposed so as to overlap the electrical component 12 as shown in FIG. 4.

  As shown in FIG. 13, in the conventional technique, when the failed electrical component 200 is replaced due to a failure of the electrical component 200, the connection between the connection wiring 201 and the electrical component 200 is released. The electric component 200 is removed from the mounting plate 202 as it is. When the electrical component 200 is taken out from the front of the housing 10, it is necessary to bend the connection wiring 201 as shown in FIG. 9, and the failed electrical component 200 may interfere with the connection wiring 201.

  However, the control panel 1 of the present invention has a configuration in which the electrical component 12 is inserted from the back side of the housing 10 and the electrical component 12 is fixed to the back side (back plate 23) via the mounting member 41. After the connection between the connection wiring 36 and the electrical component 12 is released, the electrical component 12 may be removed from the back side of the housing 10. That is, when the electric component 12 is removed, it is possible to prevent interference with the connection wiring 36, and workability can be improved.

  Further, the control panel 1 only needs to attach the attachment means 13 to the attached portion 25 of the housing 10, and positioning and attachment become easy, and the workability of the assembly work of the electrical component 12 to the back plate 23 is improved. . In particular, regarding the assembling work, the electrical component 12 can be positioned simply by inserting the groove 46 into the notch 51 and the opening 52 regardless of the skill level of the operator, so that it is easy to ensure quality.

  Moreover, the control panel 1 can also arrange | position a part of electrical component 12 to the outer side of the housing | casing 10 as needed by attachment of the electrical component 12 to the attachment means 13. FIG. In other words, by arranging the portion of the electrical component 12 that is at a high temperature outside the housing 10, it is possible to prevent the temperature inside the housing 10 from rising.

  Specifically, for example, the control panel 1 fixes the heat generating portion 37 of the inverter 31 to the suspension member 44 of the mounting member 41 when mounting the inverter 31 that is one of the electrical components 12. The mounting member 41 to which the inverter 31 is fixed is configured such that the heat generating portion 37 is disposed outside the housing 10 and the other portion is disposed inside the housing 10 and is suspended from the back plate 23. Thus, the heat generating portion 37 can be positioned outside the housing 10.

  Moreover, the attachment member 41 can expose the heat generating part 37 to outside air as much as possible by providing the opening 43a in the heat exhaust plate 43. For this reason, it becomes possible to cool the heat generating part 37 efficiently.

  In particular, the amount of heat generated by the inverter 31 is larger than that of the other electrical components 12. For this reason, the temperature rise in the control panel 1 can be achieved by disposing the heat generating portion 37 of the inverter 31 outside the housing 10. In addition, it is possible to efficiently cool. Thereby, it becomes possible to reduce the thermal influence on the other electrical components 12 and to prevent the life of the control panel 1 (each electrical component 12) from decreasing.

  Further, in the case of the electrical component 12 having a relatively heavy weight such as the inverter 31 or the like, conventionally, the electrical component 12 is attached and detached by horizontally placing the back surface of the housing 10 downward. However, when the electrical component 12 is fixed to the housing 10 by suspending the electrical component 12 by the mounting member 41 on the back plate 23 of the housing 10 as in the control panel 1 of the present invention, the housing 10 There is no need to set the sideways.

  Further, since the electrical component 12 is suspended from the back plate 23 by the mounting member 41, when the electrical component 12 is worked after the suspension, the operator hardly needs to support the electrical component 12. Thus, by using the attachment member 41, the relatively heavy electrical component 12 can be easily fixed to the housing 10.

  Furthermore, as described above, when the electrical component 12 is removed, it is possible to prevent the interference with the connection wiring 36 and to prevent the thermal influence as much as possible, so that the electrical components 12 can be arranged close to each other. It becomes. As a result, the storage space (housing 10) for the electric component 12 is reduced in size, and the degree of freedom in arrangement of the electric component 12 is improved. As a result, the control panel 1 can be reduced in size.

  As described above, according to the control panel 1 and the pump device 100 according to the present embodiment, the electrical component 12 is inserted into the control panel 1 from the back side of the control panel 1 and fixed by the mounting member 41. As a result, it is possible to prevent thermal influence and interference of the connection wiring, and to reduce the size.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the attachment member 41 of the attachment means 13 is hung by inserting the protrusion 45 into the notch 51 and the opening 52, and the groove 46 is the lower end (back plate) of the notch 51 and the opening 52. 23), the configuration in which the electric component 12 is fixed by fitting is described, but the present invention is not limited to this.

  For example, after fitting the groove portion 46 and the back plate 23 to the mounting member 41, the electric component 12 and / or the mounting member 41 may be fixed to the back plate 23 by a fastening member. Thereby, the attachment member 41 and the electrical component 12 are more firmly fixed to the housing 10. In addition, since the attachment member 41 is configured to be suspended from the back plate 23, there is no need to support the attachment member 41 when fastening with the fastening member, and the workability of fastening work by the fastening member after suspension is reduced. Good.

Furthermore, although the example mentioned above demonstrated the structure which attaches the inverter 31 to the housing | casing 10 by the attachment member 41 among the electrical components 12, it is not limited to this. Another electrical component 12 may be fixed to the back plate 23 by the attachment member 41. In addition, various modifications can be made without departing from the scope of the present invention.
