The spray booth is a home use product that can be manufactured at low cost, and since all of them are equipped with a single exhaust fan unit, mist-like particles such as a coating agent taken into the main body from the opening are fixed by the fan. Exhaust out of the main body through the filter with suction force.
Such portable spray booths must be provided at a low price and must be of a size and weight that can be moved and carried, and the fan unit and the entire device cannot be made large and complicated. The suction force cannot be changed according to the size of the object to be coated, the amount of application, and the like. Therefore, the suction force is weak when a large object is painted, and the scattered mist particles cannot be sufficiently sucked. It caused problems such as being economical.

  The present invention solves the above-mentioned problem, and it is easy to add and reduce the fan unit, and it is possible to adjust the suction force according to the application even when an inexpensive and simple fan unit is used. A booth and a spray booth kit used for the booth are provided.

The present invention relates to a spray booth provided in a box-shaped body with an intake port for taking in mist-like particles together with air and an exhaust port for exhausting air taken in from the intake port, and an opening provided detachably on the exhaust port And a fan unit detachably provided in the opening.
Further, the spray booth contains a replaceable filter in a box-shaped main body, the filter is detached from the exhaust port by removing the fan unit mounting plate, and the spray booth has two or more openings. A fan unit mounting plate provided with the same number of fan units as the opening, the spray booth, and an opening that is detachably attached to an exhaust port of the spray booth, and a single fan unit is detachably mounted Requires a spray booth set comprising a replacement mounting plate with
Furthermore, a spray booth kit applied to the spray booth comprising a replacement mounting plate having two or more openings and a single fan unit detachably provided in the openings is required.
Furthermore, it is a requirement that the mounting plate has a positioning portion that fixes the mounting direction to the main body.
In the present invention, “front” indicates the inlet side, and “rear” indicates the fan unit side.

This device allows you to adjust the suction force suitable for the application by adding and reducing the size and volume of the fan unit without increasing the size and complexity of the attached fan unit or the entire device. A booth and a spray booth kit used for it can be formed.
Even when a replaceable filter is built in, it can be easily replaced without complicating the structure.

  The spray booth of the present invention has a fan unit mounting plate as an exhaust port with respect to a box-shaped body having an intake port for taking in mist-like particles generated by spraying work and an exhaust port for exhausting air taken in from the intake port. It is formed by attaching the fan unit to the fan unit mounting plate.

The box-shaped main body (having an upper wall, a bottom wall, and both side walls) is composed of a resin molded product, a metal workpiece, a paper assembly such as corrugated cardboard, and the like. An exhaust port is provided on the surface (that is, the back surface of the main body) facing the surface.
The air inlet is an opening provided for sucking the scattering coating agent (mist-like particles) into the main body, and the main body is positioned so that the air inlet is located behind the space (work space) for spraying work. Be placed. The shape of the opening may be any shape such as a polygon such as a triangle or a quadrangle, a curved shape such as a circle or an ellipse, and an inclined wall or the like may be provided at the opening edge.
In addition, a hood for suppressing upward scattering during spray application, an apron for preventing contamination in the downward direction (that is, the work space ahead when the main body is placed), etc. are provided around the intake port. You can also.
Further, the exhaust port is a rear opening portion provided for exhausting the air sucked into the main body from the intake port directly or through a filter or the like, and is closed by the fan unit mounting plate in the present application. It is a place to be.

The inside of the box-shaped main body is hollow, and in the hollow portion (particularly, the flow passage portion formed between the intake port and the exhaust port), a porous material such as a nonwoven fabric, foam, sponge, etc. In addition, it is preferable to arrange a filter or a filter unit (which is fixed to a desired position using a resin frame or the like) formed of paper such as cardboard, cardboard, or synthetic paper.
In addition, the filter and filter unit are arranged in a replaceable form, so that they can be replaced with new ones when the coating agent accumulates over a long period of time. This eliminates the trouble of cleaning the inside and reduces the suction force. Can be difficult.

The fan unit mounting plate is a component for efficiently connecting the exhaust port of the main body and the fan unit, and is set to a size and a shape capable of closing the exhaust port, and a position for mounting the fan unit Further, one or two or more desired openings (the same number as the fan units to be mounted) are provided to communicate the main body side and the fan unit side. The fan unit mounting plate is configured to be detachable from the main body, and is mounted by, for example, screwing, fitting, pinching, magnetic bonding, or the like.
It should be noted that the number of the two or more openings (that is, the number of fan units attached) is preferably about 2 to 4 in consideration of the overall weight and size after attachment.
Further, the fan unit mounting plate can be provided with a positioning portion for fixing the mounting direction and mounting position to the main body. Thereby, even if the shape of the fan unit mounting plate is symmetrical or similar in the left-right, up-down, front-back, etc., it can be easily installed in an appropriate direction or position.
As the positioning part, a part by fitting a concavo-convex shape with the main body or a part using a clamping piece (guide groove) can be applied.

The fan unit is an air intake means that is installed one by one so as to close each opening provided in the fan unit mounting plate, and air (including a coating agent and a solvent) sucked from the air intake port Is an apparatus for efficiently discharging to the outside, and includes at least a fan and a discharge hole. Specific examples of the fan include electric fans such as a sirocco fan and a propeller fan, but a sirocco fan having a structure in which the sucked combustible organic solvent is not sent to the motor unit is particularly preferable.
In addition, since the exhaust by the fan is performed from the exhaust hole of the fan unit, attaching a duct hose to the exhaust hole makes it easy to exhaust the evaporated solvent etc. to the outside, ensuring a cleaner state. As well as being able to do so, there is also a degree of freedom in the location of the spray booth depending on the length of the hose.

When the spray booth is composed of a fan unit mounting plate having two or more openings and the same number of fan units as the openings, one opening (that is, only one fan unit is detachably attached) A spray booth set can be configured by combining replacement mounting plates with
As a result, the volume of the fan unit can be reduced. When painting small objects (ie, when the amount of application is small), remove the fan unit mounting plate from the main unit and install a replacement mounting plate. Furthermore, by installing one of the fan units installed on the fan unit mounting plate at the opening of the replacement mounting plate, the excessive suction force of the spray booth is reduced to increase the economy. Is possible. Further, when it is desired to reduce the overall weight, such as when frequently carried, the volume reduction of the fan unit by the above operation is used.
When a large object is to be coated (that is, when the amount of application is large), it can be returned to its original state (that is, provided with a plurality of fan units) and used with a strong suction force. Therefore, even when an inexpensive fan is used, it is easy to adjust the suction amount according to the application.

In addition, when the spray booth is composed of a single fan unit and a fan unit mounting plate having an opening for detachably mounting the fan unit, a shape corresponding to the fan unit mounting plate A spray booth kit comprising a replacement mounting plate having two or more openings and a number of fan units subtracted from the number of the openings can be used.
The spray booth kit allows an additional fan unit, so when painting large objects, remove the fan unit mounting plate from the main unit and install a replacement mounting plate. By installing the fan unit installed in the unit and the attached fan unit at each opening of the replacement mounting plate, it becomes possible to use with a stronger suction force, so that paint etc. can be removed from the spray booth during spraying. It is possible to more effectively suppress the scattering to the surface.
The spray booth kit can be applied to other than the spray booth equipped with one fan unit. In that case, according to the number of fan units installed in the original spray booth, the number of openings of the replacement mounting plate and the number of attached fan units are determined in such a configuration that the number of fan units can be increased.
Moreover, it is preferable that the shape of the replacement mounting plate is substantially the same as the fan unit mounting plate provided first.

  Embodiments of the present invention will be described with reference to the drawings.

  1 to 4 show a first embodiment.

FIG. 1 is a rear external perspective view of a spray booth according to the present invention.
The spray booth 1 includes a synthetic resin hollow box-shaped body 2 having a front wall 21, a side wall 22, a rear wall 23, an upper wall 24, and a bottom wall 25 (specifically, a width of 370 mm, a height of 240 mm, a depth of 130 mm). And a suction port 3 having a width of 310 mm and a height of 180 mm at the center of the front wall 21. Further, a hood 31 for preventing scattering is provided at the upper end portion and the left and right end portions of the front wall 21, and an apron 32 for suppressing contamination of the work space is provided detachably at the lower end portion and the left and right end portions. The hood 31 and the skirt 32 are made of a soft resin, and are removed from the main body 2 and folded and stored when not in use.
Further, a resin grip 241 that is gripped when the spray booth 1 is moved and carried is detachably formed on the upper wall 24 with screws.
In addition, a rectangular exhaust port 4 is formed in the rear wall 23 so as to face the intake port 3, and the intake air can be exhausted outside the main body at a short distance.

  A resin fan unit mounting plate 5 having a size and a shape capable of closing the exhaust port 4 is detachably mounted on the rear wall 23 with six screws. The fan unit mounting plate 5 is provided with two openings 51 at symmetrical positions (not shown).

  The fan units 6 are detachably attached to the openings 51 by four screws. The fan unit 6 incorporates a sirocco fan having a diameter of 80 mm and a height of 40 mm in an intake hole together with an AC motor rated at 30 W, and is closely arranged so that the intake hole covers the opening 51. Further, a discharge hole 61 that allows a duct hose to be connected is provided above the fan unit 6, and two legs 62 are formed below the fan unit 6 for stable placement, and are obtained from a resin molded product. The two fan units 6 have independent power sources.

  Further, inside the main body 2 of the spray booth 1, there is a honeycomb shape (not shown) extending in a direction perpendicular to the air inlet 3 (front wall 21), and the front wall 21 behind the honeycomb shape. Two plate-like porous filters 7, which are parallel to each other, are detachably disposed. All of the filters 7 are installed in a state of being held by pins or a support plate 26 so that they can be exchanged by dividing and opening the main body 2 in the front-rear direction.

  When the spray booth 1 having the above-described configuration is placed on a desk or floor and used indoors, the work space (apron 32) in front of the air inlet 3 is turned on with each fan unit 6 turned on and the fans started. By applying the spray to the object to be coated in the vicinity), the excessive paint, the vaporized solvent, and the like that are scattered are taken into the main body 2 from the air inlet 3. At that time, since fine particles such as paint are adsorbed to the built-in filter 7, there is almost no paint in the air sent to the fan side through the filter 7. Further, the air is exhausted from the exhaust hole 61 to the outside through the exhaust port 4 by the suction force of the fan. At that time, it is preferable to connect the one end of the duct hose to the discharge hole 61 and dispose the other end of the duct hose from the window or the like to the outside of the room to discharge the exhaust to the outside. As a result, odors such as residue and solvent are not scattered in the room, and the room can be kept in a cleaner state.

The spray booth 1 is provided with a resin replacement mounting plate 8 having an opening 81 formed substantially at the center and four screw holes provided around the opening 81 ( FIG. 2) is used when it is desired to weaken the suction force such as painting a small object or when it is desired to reduce the weight of the spray booth 1 as a whole.
At the time of replacement, after removing the fan unit 6 and the fan unit mounting plate 5 from the spray booth 1 in FIG. 1 (FIG. 3), the replacement mounting plate 8 is disposed so as to close the exhaust port 4 and is replaced with six screws. Install. At that time, the mounting direction and position can be easily determined by mounting the rib-shaped positioning portion 82 formed at the lower end of the substantially center of the replacement mounting plate 8 so as to match the groove portion 27 of the main body 2.
Further, the fan unit 6 removed from the original fan unit mounting plate 5 is newly attached to the screw hole of the replacement mounting plate 8 with four screws, so that the opening 81 and the fan intake portion are mounted. Can be exchanged reliably and easily in a state where they communicate with each other (FIG. 4).
In the spray booth 1 after replacement, it can be used in the same manner as the above-described usage method. Further, when it is desired to increase the suction force again, it is possible to return to the state in which the two fan units 6 are provided in the reverse procedure of the previous replacement method.

4 and 5 show a second embodiment (FIG. 4 is common to the first example).
FIG. 4 is a rear external perspective view of the spray booth of the present invention (equipped with one fan unit 6).
The main body 2 of the spray booth 1 has the same configuration as that shown in FIG. 1 (that is, a hollow filter 7 that accommodates a replaceable filter 7 inside), and is composed of six screws so as to close the exhaust port 4. One opening 51 is formed at substantially the center of the resin fan unit mounting plate 5 that is detachably mounted. Further, the opening 51 is detachably attached with four screws so that the intake portion of the resin fan unit 6 communicates. The fan unit 6 incorporates an AC motor rated at 30 W and a sirocco fan with a diameter of 80 mm and a height of 40 mm. The fan unit 6 is provided with a discharge hole 61 that allows a duct hose to be connected at the top, A book leg 62 is formed.

  When the spray booth 1 is used indoors, with the fan unit 6 turned on and the fan started, the spray can be applied to the object to be coated in the work space in front of the air inlet 3 (in the vicinity of the apron 32). The surplus paint that scatters, the vaporized solvent, and the like are taken into the main body 2 from the air inlet 3. At that time, since fine particles such as paint are adsorbed to the built-in filter 7, there is almost no paint in the air sent to the fan side through the filter 7. Further, the air is exhausted from the exhaust hole 61 to the outside through the exhaust port 4 by the suction force of the fan. At that time, it is preferable to connect the one end of the duct hose to the discharge hole 61 and dispose the other end of the duct hose from the window or the like to the outside of the room to discharge the exhaust to the outside. As a result, odors such as residues and solvents are not dispersed in the room, and the room can be kept in a cleaner state.

The spray booth 1 can be provided with a replacement mounting plate 8 having a similar outer shape and having a plurality of openings 81 so that the suction booth 1 can be used with a higher suction force if desired. For example, the fan unit 6 can be expanded by using a spray booth kit 9 which is obtained separately.
For example, as shown in FIG. 5, the spray booth kit 9 has a shape that can be attached so as to close the exhaust port 4 of the main body 2, and a replacement mounting plate 8 having two openings 81, An expansion kit including a single fan unit 6 attached to the opening 81 is used.

When it is desired to increase the suction force compared to the spray booth 1 in the form of FIG. 4 such as when painting a large object, the fan unit 6 and the fan unit mounting plate 5 are removed from the main body 2 and then the spray booth. The replacement mounting plate 8 (one fan unit 6 is attached) of the kit 9 is arranged so as to close the exhaust port 4 and is attached with six screws. At that time, the attachment direction and the attachment position can be easily determined by attaching the rib-like positioning portion 82 formed at the substantially lower end of the center of the replacement attachment plate 8 so as to coincide with the groove portion 27 of the main body 2. Further, the fan unit 6 removed from the original fan unit mounting plate 5 is attached to the opening 81 of the replacement mounting plate 8 (the fan unit 6 of the spray booth kit 9 out of the two openings 81 is mounted). By attaching the four screws to the side that is not provided, the expansion can be surely and easily performed in a state where the opening 81 communicates with the intake portion of the fan.
In addition, in the spray booth 1 after expansion, the two fan units 6 can be turned on and used in the same manner as described above. Further, when it is desired to weaken the suction force again, it can be returned to the state in which one fan unit 6 is provided (FIG. 4) by the reverse procedure of the previous method.

Next, a third embodiment is shown (not shown).
Except for the size of the exhaust port 4 and the method for replacing the filter 7, the configuration is the same as that of the first embodiment shown in FIG. 1.
Specifically, the upper end of the exhaust port 4 formed in the rear wall 23 extends to the upper wall 24 (a flat plate portion), and the fan unit mounting plate 5 corresponds to be able to close the exhaust port 4. It is larger in shape. Therefore, the inside of the main body can be touched with the fan unit mounting plate 5 removed, and the built-in filter 7 can be replaced when changing the suction force.
With the above configuration, the number of the fan units 6 can be increased or decreased when the filter 7 is replaced, and the filter 7 can be replaced when the number of the fan units 6 is increased or decreased. Therefore, a spray booth having a simpler structure can be obtained. Moreover, since the skeleton part (pin or support plate) holding the filter 7 can be easily taken out, the skeleton part can be made detachable.
The filter 7 can be in the form of a filter unit that can be exchanged together with a skeleton (pin or support plate) for holding, and in this embodiment, the method can be applied more easily.
