The first portion 11 is formed in a cylindrical shape. The second portion 12 is formed in a trapezoidal shape when viewed from the front. The third portion 13 is formed in a rectangular shape when viewed from the front. It should be noted that the second portion 12, for example, constitutes a pump base for setting the pump body 20 on a bottom panel. On the back of the third portion 13, a control portion including an operation panel and the like is provided. Such a housing portion 10 of the pump body 20 is, for example, composed of a resin component.

[0052] The pump body 20 is provided with a multi-purpose cross bar 50 as a support cross bar formed along the side of the housing 10. The multi-purpose cross bar 50 is Figure 2 to Figure 4 as well as Figure 6 As shown, it is a plate-like portion formed on the first portion 11 and the third portion 13 of the housing 10 and extending in the front-rear direction by a predetermined length. The multi-purpose cross bar 50 is provided on one side and the other side of the housing 10, respectively, and extends from the housing 10 in the horizontal direction. The housing 10 and the multi-purpose cross bar 50 are formed by, for example, integral molding.

[0053] The multi-purpose crossbar 50 can be used for a variety of purposes as described below. Figure 2 As shown, there are a plurality of holes 51 which penetrate the area between the housing 10 and the multi-purpose cross bar 50 in the vertical direction of the pump body 20 and are arranged side by side in the front-to-back direction. The hole 51, for example, has a plurality of first holes 52 and a plurality of second holes 53.

[0054] In the pump body 20 of the present embodiment, the first hole 52 is larger than the second hole 53 and is located further forward than the second hole 53, but the present invention is not limited thereto. The use of the multi-purpose crossbar 50 will be described below.

[0055] The solenoid 90 is housed in a cylindrical housing space 14 provided in the first portion 11 of the housing 10. The solenoid 90 includes a stator 91 and a mover (not shown). The stator 91 includes, for example, a first yoke 93a formed in a bottomed cylindrical shape with the inner circumference protruding toward the rear side, a cylindrical coil 95 housed in the first yoke 93a, and a coil frame 96 around which the coil 95 is wound. In addition, the stator 91 includes a second yoke (not shown) that seals the opening on the rear side of the first yoke 93a and fixes the coil frame 96 around which the coil 95 is wound. The first yoke 93a, the second yoke, and the mover are made of, for example, a magnetic body.

[0056] The mover is formed into a ring shape, for example, and is accommodated in a cylindrical space between the protruding portion of the inner circumference of the first magnetic yoke 93a and the rear end position of the second magnetic yoke 13b. The drive shaft 94 is fixed to the center hole of the mover by a method such as press-fitting. The drive shaft 94 is inserted through the center of the stator 91, specifically, inserted through the inner side of the inner circumference of the first magnetic yoke 93a, and is supported by the bearing 97 in a manner that allows reciprocating motion along the axial direction.

[0057] The mover is supported by a bearing (not shown) mounted on the inner periphery of the second yoke so as to be able to reciprocate in the axial direction. An annular spring storage space that is open toward the rear side is formed on the inner periphery of the first yoke 93a. A return spring 98 that applies a spring force to move the mover toward the rear is installed between the spring storage space and the mover.

[0058] The solenoid 90 thus constructed drives the drive shaft 94 in the reciprocating direction indicated by the arrow in the figure by the electromagnetic force of the coil 95 and the spring force of the return spring 98. At the top end of the drive shaft 94, a diaphragm 60 as a reciprocating member, such as a drive member, is installed by inserting a bolt 61.

[0059] The pump head 30 is formed of, for example, a resin member or a metal member such as stainless steel. The pump head 30 has a pump chamber 31 formed in the center. The pump head 30 is provided with a plurality of mounting bolts 30a ( Figure 1 ) and is installed on the front side of the shell portion 10 through the bracket portion 40.

[0060] The pump head 30 has a suction port 32 and a discharge port 33 for conveying fluid, which are connected to the pump chamber 31. The suction port 32 of the pump head 30 is connected to, for example, the lower part of the pump chamber 31. The discharge port 33 of the pump head 30 is connected to, for example, the upper part of the pump chamber 31. The pump head 30 has a first connection port 34 disposed below the suction port 32 and on the suction side of the conveying fluid. In addition, the pump head 30 has a second connection port 35 disposed above the discharge port 33 and on the discharge side of the conveying fluid. The first connection port 34 and the second connection port 35 are connected to the pump chamber 31 through the suction port 32 and the discharge port 33, respectively.

[0061] A cylindrical first connection adapter 37 having an inlet valve 36 installed therein is connected to the first connection port 34. A cylindrical second connection adapter 39 having an inlet valve 38 installed therein is connected to the second connection port 35. A hose adapter 37c is inserted and installed on the lower side of the first connection adapter 37. A cylindrical hose stopper 37d is installed on the front end side of the hose adapter 37c.

[0062] A cylindrical first joint 37a is connected to the outer peripheral portion of the lower side of the first connection adapter 37. The first joint 37a accommodates the hose stopper 37d in a manner that the hose stopper 37d can approach or move away from the hose adapter 37c. The first joint 37a connects the suction side flow path 37b of the conveying fluid extending toward the lower side of the pump head 30 through the central portion of the hose adapter 37c to the flow path 37e of the first connection adapter 37.

[0063] The second connection adapter 39 is connected to the third connection adapter 49 via a connection nut 38a. The third connection adapter 49 is, for example, formed into a cylindrical shape with a T-shaped cross section and branched in three directions. An exhaust adjustment screw 49a is connected to the upper side of the third connection adapter 49. An exhaust connector 69 ( Figure 1 The exhaust joint 69 has an exhaust passage (not shown). A hose adapter 49d is inserted and installed on the front side of the third connection adapter 49. A cylindrical hose stopper 49e is installed on the front end side of the hose adapter 49d.

[0064] A cylindrical second joint 49b is connected to the outer peripheral portion of the front side of the third connection adapter 49, and the second joint 49b accommodates the hose stopper 49e in a manner that the hose stopper 49e can approach or move away from the hose adapter 49d. The second joint 49b connects the discharge side flow path 49c of the conveying fluid extending toward the front side of the pump head 30 through the central portion of the hose adapter 49d to the second connection adapter 39 through the flow path 49f of the third connection adapter 49. It should be noted that the suction valve 36 and the discharge valve 38 are composed of a common valve cylinder of a two-stage ball valve in which the ball valve is arranged in two stages, for example, up and down.

[0065] The bracket part 40 is formed of, for example, a resin member. The bracket part 40 is disposed between the pump head 30 and the pump body 20 and is configured to be replaceable in accordance with the pump size of the pump head 30. The bracket part 40 is formed with a plurality of insertion holes (not shown) for inserting a plurality of mounting bolts 30a.

[0066] The diaphragm 60 is a member in which the insertion bolt 61 is integrally formed inside a resin such as tetrafluoroethylene resin (PTFE) and ethylene propylene rubber (EPDM). The diaphragm 60 is driven in the pump chamber 31 of the pump head 30 by the solenoid 90 accommodated in the pump body 20. The diaphragm 60 is installed in a liquid-tight manner in a state where the peripheral edge portion 63 is clamped between the bracket portion 40 and the pump head 30.

[0067] It should be noted that a diaphragm seal (not shown) is mounted on the rear side of the holder 64 disposed between the diaphragm 60 and the top end of the drive shaft 94. The diaphragm seal seals the outer peripheral surface of the drive shaft 94 and the rear end surface of the bracket portion 40, and is composed of an elastic body whose part is formed into a serpentine shape (not shown). The diaphragm seal is configured such that the part formed into the bellows shape plays the role of a buffer component, so that the sealing performance can be maintained even when the drive shaft 94 reciprocates.

[0068] It should be noted that, for example Figure 6 As shown, the housing 10 of the pump body 20 has a heat dissipation portion composed of a plurality of ridges (heat sinks) 17a on the outer wall of the first portion 11, and the ridges 17a extend along the circumferential direction of the first portion and are formed in plurality along the front-rear direction. The heat from the solenoid 90 in the storage space 14 is well dissipated to the outside through the first portion 11 and the ridges 17a. In addition, at the left and right ends of the lower side of the second portion 12 of the housing 10, a base flange portion 12a extending along the front-rear direction is formed, to which a base member described below is mounted, for example, by snapping.

[0069] [Example of installation and use of pump device]

[0070] Next, an installation example and a usage example of the pump device 100 configured as above will be described. Figure 7 It is a perspective view from the upper left side schematically showing an installation example of the pump device. Figure 8 It is a perspective view from the upper left side schematically showing an installation example of the pump device. Fig. 9 This is a perspective view from the upper right side schematically showing an example of use of the pump device. Fig.10 This is a perspective view from the upper right side schematically showing an example of use of the pump device.

[0071] The pump device 100 of this embodiment can be installed in the following state, for example, so that the installation freedom of the pump body 20 can be improved. Figure 7 As shown, when the pump device 100 is installed on a bottom plate, for example, the second portion 12 of the housing 10 of the pump body 20 can be installed on a rectangular base member 17 pre-installed on a bottom plate (not shown) of the installation object.

[0072] Specifically, the left and right base flanges 12a of the second portion 12 of the shell 10 are, for example, fitted into a plurality of engaging grooves (not shown) of the base member 17. Then, a pair of left and right first engaging claws 17b formed corresponding to the plurality of engaging grooves are respectively engaged and fixed to the base flanges 12a, and the pump device 100 is set on the bottom panel through the base member 17. It should be noted that, in the case where the pump device 100 is set on the bottom panel, it can also be as shown in FIG. Figure 6 As shown, the pump device 100 is directly fixed to the bottom plate by using the flange hole 12b without using the base member 17.

[0073] In addition, in Figure 8 As shown, when the pump device 100 is set on a wall, for example, the shell portion 10 of the pump body 20 is moved slidingly from top to bottom in a manner such that the multi-purpose cross bar 50 is engaged with a second engaging claw (not shown) formed on a rectangular base member 17 pre-set on the wall surface (not shown) of the setting object.

[0074] Then, the second engaging claws can be inserted from the lower side into the first holes 52 of the holes 51 formed in the pump body 20 and the two can be engaged and fixed, and the pump device 100 can be installed on the wall through the base member 17. Since the multi-purpose cross bar 50 is provided on both the left and right sides of the housing 10, the pump body 20 can be installed by mounting the right side or the left side of the housing 10 on the wall side.

[0075] In addition, the pump device 100 of this embodiment can use the multi-purpose crossbar 50 in the following manner, so that various components can be installed on the pump body 20 for various purposes. Fig. 9As shown, when the box member 18 is mounted on the pump body 20, for example, the hook claws (not shown) pre-formed on the box member 18 are inserted from above into the first holes 52 of the holes 51 formed on the multi-purpose cross bar 50 of the housing 10, and are hooked on the multi-purpose cross bar 50. In this way, the box member 18 can be mounted on the side of the pump body 20 for use. The multi-purpose cross bar 50 is provided on both the left and right sides as described above, so the box member 18 can also be mounted on either or both of the multi-purpose cross bars 50 on the left and right sides.

[0076] It should be noted that the box component 18, although not shown in the figure, may be a control box that aggregates at least one of the electrical system and the control system of the pump device 100, or a component such as a relayed junction box, but is not limited to this, and may also be a box-shaped component used in association with the control, operation, maintenance management, etc. of the pump device 100.

[0077] In addition, if Fig.10 As shown, for example, the hexagonal wrench 19 for the mounting bolt 30a of the pump head 30 can also be attached to the pump body 20 as a maintenance member for the pump device 100. In this case, for example, the long side of the L-shaped hexagonal wrench 19 is inserted into any of the second hole portions 53 of the hole portion 51 formed on the multi-purpose crossbar 50 of the housing portion 10. The hexagonal wrench 19 is often used to re-tighten the mounting bolt 30a, so the maintenance of the pump device 100 can be easily performed.

[0078] Although the embodiments of the present invention are described above, the embodiments are only presented as examples and are not intended to limit the scope of the present invention. The novel embodiments can be implemented in various other ways, and various omissions, substitutions, and changes can be made without departing from the gist of the utility model. These embodiments and their variations are also included in the scope and gist of the utility model, and are included in the scope equivalent to the utility model recorded in the scope of the utility model.

[0079] For example, in the above-mentioned embodiment, the hole portion 51 of the multi-purpose cross bar 50 is configured to be composed of a plurality of first hole portions 52 and second hole portions 53, but the hole portion 51 may also be configured to include other hole portions in addition to these hole portions 52 and 53 for the purpose of installing other components that can be installed on the pump body 20. In addition, the size and arrangement order of the first hole portion 52 and the second hole portion 53 may also be different from those described above. In addition, the hole portion 51 may also be composed of either the first hole portion 52 or the second hole portion 53. In addition, the multi-purpose cross bar 50 may also be provided on only one side of the housing portion 10.

[0080] In addition, although in the above-mentioned embodiment, the second part 12 and the base member 17, and the multi-purpose cross bar 50 and the box member 18 are respectively installed and fixed by engagement or hooking, it is not limited to this, and various known locking mechanisms (one-motion lock, automatic lock) can also be provided to fix them to each other. The multi-purpose cross bar 50, for example, as described above, is a member that can function in either case, whether it is a support cross bar that allows the pump body 20 to actively support the box member 18, or a support cross bar that allows the pump body 20 to be passively supported by the base member 17 installed on the wall.
