Description

Technical Field

[0001] The present invention relates to a cushioning material used for packaging an embedded blower. How to use

Background Art

[0002] For example, when storing or transporting an embedded blower such as a ventilation fan, the embedded blower is packaged in a cushioning material and stored.

[0003] Conventionally, as this type of cushioning material, for example, a packaging body of a ventilation fan shown in Patent Document 1 is known. Hereinafter, the packaging body will be described with reference to FIGS. 10 and 11.

[0004] The packaging body forms a single packaging material 200 in a rectangular plate shape in the unfolded state as shown in FIG. 10. The packaging body also includes four peripheral wall surfaces 201a to 201e that are an outer peripheral packaging portion having a substantially rectangular cross-sectional shape as shown in FIG. 11, and four fold lines 200a for forming the peripheral wall surfaces 201a to 2…

[0005] By holding the outer periphery of the ventilation fan 100 by the ventilation fan holding portions 202 and 203, the packaging body separates the ventilation fan 100 from the peripheral wall surfaces 201a to 201e, suppresses the impact on the peripheral wall surfaces 201a to 201e from being directly transmitted to the ventilation fan 100, and can protect the ventilation fan 100, that is, the product.

[0006] Also, according to the prior art, before being bent and assembled, since it is a single packaging material in a substantially rectangular shape, the efficiency of member cutting when cutting out this packaging material from a large raw material is high. Also, since this packaging body unfolded again after unpacking is a single packaging material in a substantially rectangular shape, the storage space can be reduced, and it is also easy to assemble it again and use it as a packaging body, and it is said that the recyclability is high. ​[Prior art documents] [Patent Documents]

Embodiments for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments are an example of embodying the present invention and do not limit the technical scope of the present invention. Also, throughout all the drawings, the same parts are denoted by the same reference numerals, and the description thereof is omitted or simplified after the second time. Further, in each drawing, the details of the parts not directly related to the present invention are omitted from the description.

[0014] (Embodiment 1) First, referring to FIGS. 1 and 2, the configuration of the built-in blower 20 will be described. Note that FIG. 1 is an exploded perspective view of the built-in blower 20, and FIG. 2 is a bottom view of the built-in blower 20.

[0015] As shown in FIGS. 1 and 2, the built-in blower 20 includes a housing 1, a blower unit 2, and an adapter 3.

[0016] The housing 1 has a box shape with an open bottom and at least one open side surface, and the material is metal or resin. The housing 1 has a suction port 4 on the lower surface and a blowout port 5 on the side surface where the adapter 3 is mounted.

[0017] The suction port 4 is provided on the bottom surface facing downward vertically, that is, in the direction from the ceiling to the ground, when the built-in blower 20 is installed on the ceiling with the lower surface of the built-in blower 20 aligned with the surface of the ceiling board. That is, the opening of the bottom surface of the housing 1 corresponds to the suction port 4. The intake of air into the housing 1 is performed through the design panel 21 of the lattice structure shown later provided at the opening of the bottom surface.

[0018] The blowout port 5 is provided as an opening on one side surface adjacent to the bottom surface where the suction port 4 is provided and on the side surface where the adapter 3 is arranged.

[0019] The suction port 4 and the blowout port 5 are communicated inside the housing 1, and the communicated air passage constitutes the exhaust air passage 6.

[0020] The blower unit 2 is arranged in the exhaust air passage 6 and guides air from the suction port 4 to the blowout port 5. The blower unit 2 includes a casing 7, a motor 8, and a fan 9.

[0021] The casing 7 forms the outer shell of the blower unit 2, and the material is resin. The casing 7 has a substantially cylindrical shape, and has an opening for sucking air on the bottom surface located on the lower surface and an opening for discharging air on the side surface. The opening of the bottom surface of the casing 7 is close to the suction port 4 of the housing 1, and the opening of the side surface of the casing 7 is connected to the blowout port 5 of the housing 1. The casing 7 has a substantially cylindrical shape and a circular scroll shape in a cross section parallel to the bottom surface. The casing 7 has an orifice 10 at the opening of the bottom surface.

[0022] The orifice 10 is a cylindrical resin component with an opening in its center, which is connected to an opening in the bottom of the casing 7. The orifice 10 is located upstream in the airflow direction of the blower unit 2 and is attached to the casing 7 by fastening means such as screws. The orifice 10 may also be an integral part of the casing 7.

[0023] The motor 8 is positioned on the top side of the internal space of the casing 7 and is attached to the central part of the circular scroll shape by fastening means such as screws. The motor 8 has a rotating shaft that protrudes from the top surface to the bottom surface of the casing 7. The motor 8 rotates its rotating shaft by power supply. Power is supplied to the motor 8 via an electrical circuit board (not shown).

[0024] Fan 9 is, for example, a sirocco fan fixed to the rotating shaft of motor 8. Fan 9 rotates as the rotating shaft rotates via motor 8, causing air to move. In other words, the air blower 2 drives air from the intake port 4 to the outlet port 5.

[0025] The electrical circuit board is housed in an electrical circuit board case 11 located inside the housing 1 and is attached to the outer casing 7 by fastening means such as screws (not shown).

[0026] The electrical circuit board case 11 comprises an electrical circuit board base 11a made of flame-retardant resin and an electrical circuit board cover 11b also made of flame-retardant resin. The electrical circuit board is attached to the electrical circuit board base 11a by fastening means such as screws. The electrical circuit board cover 11b is also attached to the electrical circuit board base 11a by fastening means such as screws.

[0027] The adapter 3 is located on one side of the housing 1, downstream of the air outlet 5. The adapter 3 comprises an adapter plate 12 and a duct connection portion 13.

[0028] The adapter plate 12 is a flat plate, for example, made of resin, which is approximately the same size as one side of the housing 1, and is installed on the downstream side of the side of the housing 1 where the air outlet 5 is provided.

[0029] The duct connection section 13 is erected from the adapter plate 12 toward the downstream side, and has a rectangular shape on the upstream side and a cylindrical shape on the downstream side. The duct connection section 13 is connected to the outlet 5 through its internal space and guides the exhaust air blown out from inside the housing 1. By connecting, for example, the indoor end of a duct that connects the indoors and outdoors to the duct connection section 13, the exhaust air from the embedded blower 20 can be discharged outdoors.

[0030] Next, the packaging state of the embedded fan 20 and the configuration of the cushioning material 30 will be explained with reference to Figures 3, 4, and 5. Figure 3 is an exploded perspective view of the embedded fan 20 in its packaging state, Figure 4 is a perspective view of the cushioning material 30 in its packaging state, and Figure 5 is a plan view of the cushioning material 30 in its unfolded state. Here, the unfolded state refers to a state in which the cushioning material 30 is not packaging the product, in this case the embedded fan 20, and is not in a packaged state, but rather a state in which the three-dimensional shape shown later can be released. In other words, it can be called the unpacked state.

[0031] The cushioning material 30 is used for packaging the built-in blower 20, as shown in Figure 3. The cushioning material 30 is made mainly of corrugated cardboard, which is bendable and has a certain degree of elasticity. The packaged state of the built-in blower 20 includes the cushioning material 30, the built-in blower 20, the mounting hardware 22, and the outer box 39.

[0032] The design panel 21 has a hollow rectangular shape, and the hollow portion has a lattice structure, allowing air to pass through. The design panel 21 is attached to the opening on the bottom of the housing 1 of the embedded blower 20.

[0033] The mounting bracket 22 is a hollow rectangular frame that assists in the installation of the recessed blower 20 to the ceiling. The mounting bracket 22 is equipped with projections 23 that protrude inward from the inner surface of the frame. Specifically, the projections 23 are screws that are used to fix the mounting bracket 22 to the wooden frame 38, which will be described later.

[0034] As shown in Figure 4, the cushioning material 30 forms a three-dimensional shape that partially matches the shape of a predetermined component such as the embedded blower 20 when packaged, and can form a flat plate shape when the packaging is removed, as shown in Figure 5.

[0035] The three-dimensional shape of the cushioning material 30 includes an isolation portion 33 formed by folding a part or all of one side 42 that constitutes the flat plate shape at a predetermined angle with respect to the plane forming the flat plate shape. Specifically, the isolation portion 33 is formed by folding both ends of the cushioning material 30 at a 90-degree angle to the back side 32 along the bent portion 40 shown by the dashed line in Figure 5.

[0036] Furthermore, the cushioning material 30 has a recess 34 that is recessed from the surface side 31 to the back side 32 on the inner circumference side of the isolation portion 33. Specifically, two parallel cuts are made from the isolation portion 33 to the plane forming the flat plate shape, and the recess 34 is formed by folding and raising the area near the center of the cut portion sandwiched between these two cuts on the opposite side from the bent portion 40.

[0037] Furthermore, as shown in Figure 5, the cushioning material 30 has a flat plate shape and is provided with a slit 35 that matches the outer circumference of the mounting hole 36 (described later in Figure 6) provided in the ceiling for embedding the housing 1 of the embedded blower 20. Here, "matching" does not mean that they must match exactly; matching also includes slits 35 that are slightly larger in size to allow for a margin of error in embedding the housing 1 into the mounting hole 36.

[0038] The slit 35 is a linear gap that penetrates the plane forming the flat plate shape, and the short sides of the linear gap are adjacent to each other to form a rectangular ring. The width of the short side of the slit 35 is such that the tip of the writing instrument 41 can pass through it. The length of the long side of the slit 35 and the distance between adjacent short sides should be such that the inside and outside of the rectangular ring are not easily separated. However, it is undesirable to form a slit such that the length of the long side of the slit 35 is too short or the distance between adjacent short sides is too long, making it difficult to recognize it as a ring.

[0039] In the packaged state, as shown in Figure 3, cushioning material is placed on the bottom surface of the outer box 39, and the housing 1 and adapter 3 of the built-in blower 20 are placed on top of that. Next, the design panel 21 is placed on the upper part of the housing 1, then the cushioning material 30 is placed on the upper part of the design panel 21, and then the mounting hardware 22 is placed in this order. In other words, predetermined components that make up the built-in blower 20, such as the design panel 21, are placed on the back side 32 (lower side in Figure 3) of the cushioning material 30. Components other than the predetermined components, such as the mounting hardware 22, are placed on the front side 31 (upper side in Figure 3), which is the back surface of the back side 32 of the cushioning material 30.

[0040] In the packaged state, the two long ends of the isolation section 33 are positioned on the outer periphery side of the design panel 21, and the flat surface of the cushioning material 30 is positioned so that it is slightly raised from or slightly in contact with the design panel 21. Furthermore, the mounting hardware 22 is positioned above the cushioning material 30.

[0041] The isolation section 33 can separate a predetermined component (design panel 21) that forms the embedded blower 20, which is located on the rear side 32 and on the inner circumference side of the isolation section 33, from a different component (installation fitting 22) that is located on the front side 31 and on the outer circumference side of the isolation section 33 or on the isolation section 33.

[0042] In this way, the flat surface forming the flat plate shape of the cushioning material 30 separates the design panel 21 and the mounting hardware 22, that is, it is sandwiched between a predetermined component and a component different from the predetermined component, thereby preventing the mounting hardware 22, which is made of a hard material, from damaging the design panel 21, which is made of a soft material.

[0043] Furthermore, in the packaged state, the recess 34 can house the projection 23 that protrudes toward the inner circumference of components other than the predetermined components, such as the mounting hardware 22, and isolate it from the predetermined components such as the design panel 21.

[0044] Finally, the method of using the cushioning material 30 during construction will be explained with reference to Figures 6, 7, and 8. Figure 6 is a bottom perspective view showing the method of using the cushioning material 30, Figure 7 is a perspective view showing the method of installing the installation fittings 22, and Figure 8 is a perspective view showing the method of installing the embedded blower 20.

[0045] First, as shown in Figure 6, the installer returns the three-dimensional shape of the unpacked cushioning material 30 back to a flat shape and presses it against the ceiling material 37 on which the embedded blower 20 will be installed.

[0046] Next, the worker inserts the tip of the writing instrument 41 into the slit 35 of the cushioning material 30 and draws a circular guideline along the slit 35.

[0047] Next, the cushioning material 30 is removed from the ceiling material, and a mounting hole 36 is made in line with the guideline drawn on the ceiling material 37. In other words, the mounting hole 36 is an opening for installing the built-in blower 20.

[0048] Subsequently, as shown in Figure 7, the mounting bracket 22 is positioned on the ceiling side through the embedded hole 36 and fixed to the wooden frame 38.

[0049] Next, as shown in Figure 8, the adapter 3 is installed on the mounting bracket 22, then the housing 1 inserted through the embedded hole 36 is connected to the adapter 3, and the housing 1 is fixed to the mounting bracket 22. Finally, a decorative panel 21 (not shown) is installed in the opening on the bottom of the housing 1. The embedded fan 20 is installed using these procedures.

[0050] In other words, since the cushioning material 30 has a slit that matches the outer circumference of the mounting hole 36 for embedding the embedded blower 20, it is possible to easily create an opening in the ceiling for product installation by drawing a mark according to the slit 35. Therefore, the work of the installer, which previously involved checking the opening size in the installation manual and then marking it using a measuring instrument, can be simplified. As a result, by giving the cushioning material an additional function that can be used during product installation, the usefulness of the cushioning material can be further enhanced.

[0051] (modified version) Figure 9 shows an example where the ring shape of the slit 35 of the cushioning material 50 is circular. In other words, the outer diameter shape of the cushioning material can be circular, elliptical, or other shapes to match the shape of the embedded blower. [Industrial applicability]

[0052] The cushioning material according to the present invention makes it possible to easily create an opening for product installation in the ceiling by drawing marks according to the slits, and is therefore useful for packaging built-in blowers and as an auxiliary tool for installation work.
