Description

  The present invention relates to a cover for refrigerant piping.

  2. Description of the Related Art Conventionally, there is known a refrigerant pipe cover that covers a refrigerant pipe for circulating a refrigerant between an indoor unit and an outdoor unit of an air conditioner. The refrigerant pipe cover includes two constituent members that are coupled to each other, and the refrigerant pipe is passed between the two constituent members. Then, when attaching the refrigerant pipe to such a pipe cover, the operator pushes the refrigerant pipe into the inside of one of the components arranged behind the refrigerant pipe, and then holds the state with the other hand. It was necessary to cover the component member on the refrigerant pipe and to be coupled to one component member, and the installation work was complicated.

  Therefore, Patent Document 1 below discloses a technique that can reduce the complexity of the operation of attaching the refrigerant pipe to the pipe cover of the air conditioner.

  In the technique disclosed in Patent Document 1, the refrigerant pipe is fixed to a saddle attached to the inner surface of one constituent member of the pipe cover with a band, so that the refrigerant pipe is pushed inside the one constituent member. It fixes with respect to one structural member. The saddle is provided with an insertion hole for inserting the band at a position spaced from the bottom surface, and a portion of the saddle forming the upper portion of the insertion hole is used for fixing the refrigerant pipe with the band. It has become. According to this technique, since the attachment portion capable of fixing the band is disposed inside the component member, the refrigerant pipe is held even if it is not pressed by hand while being pushed inside the one component member. can do. For this reason, it is possible to reduce the complexity of the operation of attaching the refrigerant pipe to the pipe cover.

No. 2-19675

  However, in the technique of Patent Document 1, a saddle is required as a separate member to fix the refrigerant pipe to one constituent member of the pipe cover, and thus the number of parts increases.

  Further, when the saddle is attached to the inner surface of one component member, the refrigerant pipe hits the saddle attachment portion inside the one component member, so that the height position of the saddle attachment portion from the inner surface of the component member in the region other than the saddle Refrigerant piping cannot be arranged in the space up to. And in the said saddle, since the insertion hole for inserting a band in the position spaced apart from the bottom face is provided, and the part which comprises the upper part of the insertion hole is an attachment part, one component member's The distance from the inner surface to the height position of the saddle mounting portion increases, and the space in which the refrigerant pipe cannot be arranged increases. As a result, there arises a problem that the space for arranging the refrigerant pipe in the pipe cover is greatly reduced.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to reduce the number of parts and reduce the space for arranging the refrigerant pipe in the refrigerant pipe cover, while reducing the refrigerant pipe. It is to reduce the complexity of the work of attaching the refrigerant pipe to the cover.

  In order to achieve the above object, a refrigerant pipe cover according to the present invention is a refrigerant pipe cover provided with two constituent members that form an internal space through which refrigerant pipes are coupled to each other. A mounting portion for fixing the refrigerant pipe with a bundling member is integrally formed on the inner surface of one of the constituent members.

  In this refrigerant pipe cover, since the attachment portion is formed on the inner surface of one component member, the refrigerant pipe can be fixed to the attachment portion by the bundling member in a state where the refrigerant pipe is arranged inside the one component member. it can. For this reason, in order to hold | maintain the refrigerant | coolant piping in the state arrange | positioned inside one structural member, it is not necessary for the operator to hold down refrigerant | coolant piping with respect to one structural member by hand. As a result, it is possible to reduce the complexity of the operation of attaching the refrigerant pipe to the refrigerant pipe cover. In addition, in this refrigerant pipe cover, since the attachment portion is integrally formed with one component member, unlike the conventional configuration in which a saddle for fixing the refrigerant pipe is attached to one component member, the number of parts is reduced. An increase can be prevented. Further, in this refrigerant pipe cover, since the attachment portion is integrally formed on the inner surface of one of the constituent members, an insertion hole is provided at a position spaced from the bottom surface, and a portion forming the upper portion of the insertion hole is provided. Compared to the conventional configuration in which the saddle serving as the attachment portion is attached to the inner surface of the piping cover, the attachment portion can be disposed at a position close to the inner surface of one component member. For this reason, the useless space formed between the inner surface of one component member and the height position of the attachment portion in the region other than the attachment portion can be reduced. As a result, it is possible to suppress a decrease in the space for arranging the refrigerant pipe in the refrigerant pipe cover as compared with the conventional configuration. Therefore, in this configuration, it is possible to reduce the complexity of installing the refrigerant pipe to the refrigerant pipe cover while suppressing an increase in the number of parts and a reduction in the space for arranging the refrigerant pipe in the refrigerant pipe cover. it can.

  In the above refrigerant pipe cover, the one component member is provided with a through-hole penetrating the one component member in the thickness direction, and the attachment portions are respectively provided on both sides of the attachment portion in the width direction. It is preferable to extend across the through hole so that a predetermined region of the through hole is disposed.

  If the mounting portion is provided in an arch shape on the inner surface of one component member and no through hole is formed at the location where the mounting portion is provided, one component member can be molded with a resin material. When molding, it is necessary to provide a mold member for forming a space between the inner surface of one component member and the attachment portion separately from the mold for forming the other part. Then, after one component member is molded, when one component member is removed from the mold, an operation of removing the mold member is required in addition to the operation of separating the mold for molding the outer surface and the inner surface of the one component member. . On the other hand, in this configuration, the attachment portion extends across the through hole so that the predetermined region of the through hole is disposed on each side of the attachment portion in the width direction. A mold member for forming the space and the through hole is formed integrally with a mold for molding the outer surface of one component member, and after molding one component member, the inner surface of one component member is molded. When separating the mold to be molded and the mold to mold the outer surface, the mold member can be pulled out from the through hole of one component member at the same time. Therefore, in this configuration, it is possible to prevent an increase in the number of molding members for molding one component member, and it is possible to prevent the molding process of one component member from becoming complicated.

  In this case, the edge portion of the through hole has a portion extending in the length direction of the attachment portion, and the portion extends from the attachment portion toward the inner surface side of the one component member in the thickness direction. It is preferable that a tapered surface that is inclined so as to move away is formed.

  If the edge of the through hole extends in the length direction of the attachment part on the vertical surface, the bundling member passes through the attachment part by passing from the tip to the back side of the attachment part. There is a possibility that the leading end of the binding member collides with the vertical surface of the edge of the hole, making it difficult to pick up the leading end. On the other hand, when the tapered surface is formed in the portion extending in the length direction of the attachment portion in the edge portion of the through hole as in this configuration, the binding member is passed from the tip portion to the back side of the attachment portion. Even if the leading end of the binding member hits the tapered surface at this time, the leading end of the binding member rises along the tapered surface. For this reason, after passing the binding member from the front end to the back side of the mounting portion, the front end can be easily taken up, and as a result, the workability of the work of hanging the binding member on the mounting portion is improved. Can do.

  In the refrigerant pipe cover, the refrigerant pipe may have a bent portion, and the two constituent members may form the bent inner space that can accommodate the bent portion in a state of being coupled to each other.

  According to this configuration, the bent portion of the refrigerant pipe can be accommodated in the bent internal space formed by the two components, and the bent portion can be covered with the refrigerant pipe cover. However, when the bent portion of the refrigerant pipe is attached to the cover for the refrigerant pipe, even if the bent portion of the refrigerant pipe is arranged inside one of the constituent members, the bent portion is fitted to the bent shape of the one constituent member. However, there is a risk of jumping out of the constituent members. However, according to this configuration, the bent portion of the refrigerant pipe can be fixed to the attachment portion formed on the inner surface of the one component member with the binding member, so that the bent portion is disposed inside the one component member. In such a state, it can be held so as not to jump out.

  In this case, the bent portion of the refrigerant pipe is a portion that protrudes from the wall surface of the building through a hole provided in the wall of the building and is bent along the wall surface of the building, The constituent member may be disposed between a portion of the bent portion along the wall surface of the building and the wall surface.

  According to this configuration, the bent internal space formed by the two components is formed by bending the refrigerant pipe bent along the wall surface of the building through the hole in the wall of the building and bent along the wall surface of the building. And the bent portion can be covered with a refrigerant pipe cover. However, when the bent portion that protrudes from the wall of the building through the hole in the building wall and is bent along the wall of the building is attached to the refrigerant pipe cover, the wall surface of the building of the bent portion The part along the line tends to float up in a direction away from the wall surface of the building with respect to one component member. However, according to the present configuration, the portion along the wall surface of the building among the bent portions can be fixed to the attachment portion provided on the inner surface of one of the constituent members with the binding member. It can be held so that it does not lift up against.

  In the refrigerant pipe cover, it is preferable that the attachment portion is provided in a region of the inner surface of the one component member that faces the other component member.

  If the attachment part is provided in the area | region which opposes the other structural member among the inner surfaces of one structural member like this structure, a refrigerant | coolant piping is made into one structure by fixing a refrigerant | coolant piping to a mounting part with a binding member. It can fix in the position of the area | region vicinity which opposes the other structural member among the inner surfaces of a member. For this reason, it becomes easy to prevent the refrigerant pipe from floating from one component member to the other component member side and jumping out.

  In the refrigerant pipe cover, the two constituent members are coupled to each other to form one opening that forms one end of the internal space and the other opening that forms the other end of the internal space. The attachment portion preferably extends in a direction along the refrigerant pipe disposed in the internal space through the one opening and the other opening.

  If the attachment portion extends in a direction along the refrigerant pipe arranged in the internal space through one opening and the other opening of the refrigerant pipe cover as in this configuration, the binding member is attached to the attachment portion. This makes it easier to hang in the direction that intersects the refrigerant piping. For this reason, it becomes easy to bind refrigerant | coolant piping by the binding member hung on the attaching part.

  In the refrigerant pipe cover, the attachment portion connects a pair of standing portions that are separated from each other on the inner surface of the one component member and the tip portions of the pair of standing portions. It is preferable to have a hook part for hanging the binding member.

  According to this configuration, since the hook portion of the attachment portion is disposed at a position separated from the inner surface of one of the constituent members, the front end portion of the binding member can be easily attached to the rear side of the hook portion when the binding member is hung on the attachment portion. Can be passed. For this reason, workability | operativity of the operation | work which puts a binding member on an attachment part can be improved.

  As described above, according to the present invention, it is difficult to attach the refrigerant pipe to the refrigerant pipe cover while suppressing an increase in the number of parts and a reduction in the space for arranging the refrigerant pipe in the refrigerant pipe cover. Can be reduced.

In this state, the screw is inserted into the fixing hole 12c, and the first component member 2 is fixed to the wall surface by screwing the screw into the building wall with a screwdriver.

  Next, the binding band 105 is hung on the attachment portion 13. At this time, while moving the binding band 105 in the width direction of the first component member 2, the back side of the hanging portion 13 b of the attachment portion 13 is passed from the tip portion. At this time, the tip of the binding band 105 may abut against the tapered surface 12i of the edge 12f of the through hole 12e. Even in this case, the tip of the binding band 105 is on the inner surface side of the base 12 along the tapered surface 12i. Float up. Then, the refrigerant pipe 100 and the wiring 102 are bent downward and placed inside the first component 2 with the binding band 105 passed through the back side of the hook 13b. In this state, a portion of the refrigerant pipe 100 and the wiring 102 along the wall surface of the building is bound to the hanging portion 13b by a binding band 105. In this way, the refrigerant pipe 100 and the wiring 102 are fixed to the attachment portion 13 of the first component member 2.

  Next, the second constituent member 4 is put on the bent portion of the refrigerant pipe 100 and the wiring 102 and fitted to the first constituent member 2 with the end wall 32b of the main body 32 positioned on the upper side. At this time, the inner surface of the corresponding side wall portion 32c of the second component member 4 is in contact with the outer surface of each side wall portion 14 and each screw receiving support portion 16 of the first component member 2, and each locking portion of the first component member 2 18 engages with the corresponding engaged portion 36 of the second component member 4, and the engagement portion 38 of the second component member 4 engages with the tip of the screw receiving portion 20 of the first component member 2. In this manner, the second component member 4 is fitted to the first component member 2.

  Finally, each fastening screw 6 is inserted into each insertion hole 32i of the second component member 4, and each of the fastening screws 6 is screwed into the hole portion 20a of the screw receiving portion 20 of the first component member 2 with a screwdriver. Thus, the second component member 4 is fastened to the first component member 2.

  In this way, the operation of fixing the refrigerant pipe cover to the wall surface of the building and fixing the refrigerant pipe 100 and the wiring 102 to the refrigerant pipe cover is performed.

  As described above, in the refrigerant pipe cover according to the present embodiment, since the attachment portion 13 is formed on the inner surface of the base portion 12 of the first component member 2, the refrigerant pipe 100 and the wiring 102 are connected to the first component member 2. The refrigerant pipe 100 and the wiring 102 can be fixed to the attachment portion 13 by the binding band 105 in a state of being disposed inside. For this reason, in order to hold | maintain the refrigerant | coolant piping 100 and the wiring 102 in the state arrange | positioned inside the 1st structural member 2, an operator hold | suppresses the refrigerant | coolant piping 100 and the wiring 102 with respect to the 1st structural member 2 by hand. There is no need. As a result, it is possible to reduce the complexity of attaching the refrigerant pipe 100 and the wiring 102 to the refrigerant pipe cover.

  Moreover, in the refrigerant pipe cover of the present embodiment, since the attachment portion 13 is formed integrally with the first component member 2, an increase in the number of parts can be prevented. Furthermore, in the cover for refrigerant piping of the present embodiment, the attachment portion 13 is formed integrally with the inner surface of the base portion 12 of the first component member 2, so that an insertion hole is provided at a position spaced from the bottom surface and the insertion portion is inserted. Compared to a conventional configuration in which a saddle having a portion forming the upper portion of the hole as an attachment portion is attached to the inner surface of the piping cover, the attachment portion 13 can be disposed at a position close to the inner surface of the base portion 12. For this reason, the useless space formed between the inner surface of the base portion 12 of the first component 2 and the height position of the attachment portion 13 in the region other than the attachment portion 13 can be reduced. As a result, it is possible to suppress a reduction in space for arranging the refrigerant pipe 100 and the wiring 102 in the refrigerant pipe cover as compared with the conventional configuration. Therefore, in the present embodiment, while suppressing an increase in the number of parts and a decrease in a space for arranging the refrigerant pipe 100 and the wiring 102 in the refrigerant pipe cover, the refrigerant pipe 100 and the wiring 102 with respect to the refrigerant pipe cover are suppressed.

For this reason, the mold member for forming the space on the back side of the attachment portion 13 and the through hole 12e is formed integrally with the mold for molding the outer surface of the first component member 2, and the first component member 2 is formed. After the molding, when the mold for molding the inner surface of the first component 2 and the mold for molding the outer surface are separated, the mold member can be removed from the through hole 12e of the first component 2 at the same time. Therefore, in this embodiment, it is possible to prevent the number of mold members for molding the first component member 2 from increasing, and to prevent the molding process of the first component member 2 from becoming complicated.

When passing through the hanging portion 13b, the leading end portion of the binding band 105 may collide with the surface of the first portion extending in the thickness direction, making it difficult to pick up the leading end portion. On the other hand, when the tapered surface 12i is formed on the first portion 12g of the edge portion 12f of the through hole 12e as in the present embodiment, the binding band 105 is passed from the tip portion to the back side of the hanging portion 13b. Even when the leading end of the binding band 105 hits the tapered surface 12i, the leading end of the binding band 105 rises along the tapered surface 12i. For this reason, after passing the binding band 105 from the front end portion to the back side of the hanging portion 13b, the front end portion can be easily taken up. As a result, workability of the operation of hanging the binding band 105 on the attachment portion 13 is improved. Can be improved.

For this reason, the bent part of the refrigerant | coolant piping 100 and the wiring 102 which protrude from the wall surface of a building can be accommodated in the bent internal space formed of both the structural members 2 and 4, and the said bent part can be covered with the cover for refrigerant | coolant piping. . When the bent portions of the refrigerant pipe 100 and the wiring 102 that protrude from the wall of the building through the hole in the building wall and are bent along the wall surface of the building are attached to the cover for the refrigerant pipe, the bent portion is used. Of the portion, the portion along the wall surface of the building tends to float in a direction away from the wall surface of the building with respect to the first component 2. However, according to the present embodiment, the portion along the wall surface of the building among the bent portions can be fixed to the attachment portion 13 provided on the inner surface of the first component member 2 with the binding band 105. The first component member 2 can be held so as not to float.

  Moreover, in this embodiment, since the attaching part 13 is provided in the inner surface of the base 12 which opposes the 2nd structural member 4 among the 1st structural members 2, the refrigerant | coolant piping 100 and the wiring 102 are tied to the attaching part 13 and a binding band. By fixing at 105, the refrigerant pipe 100 and the wiring 102 can be fixed at a position near the inner surface of the base 12 of the first component 2. For this reason, it becomes easy to prevent the refrigerant | coolant piping 100 and the wiring 102 from rising from the 1st component 2 to the 2nd component 4 side, and jumping out.

  Moreover, in this embodiment, the attachment part 13 is refrigerant | coolant piping arrange | positioned in the internal space of the cover for refrigerant | coolant piping through one opening part formed by the coupling | bonding of both the structural members 2 and 4, and the other opening part. Since it extends in a direction along 100, the binding band 105 can be easily hung on the attachment portion 13 in a direction intersecting the refrigerant pipe 100 and the wiring 102. For this reason, it becomes easy to bind the refrigerant pipe 100 and the wiring 102 by the binding band 105 hung on the attachment portion 13.

  Moreover, in this embodiment, the attachment part 13 connects a pair of standing part 13a standingly arranged in the mutually spaced-apart position of the inner surface of the base 12, and the front-end | tip parts of the pair of standing part 13a. And a hook 13b provided as described above. For this reason, the hook portion 13 b of the attachment portion 13 is disposed at a position spaced from the inner surface of the base portion 12. As a result, when the binding band 105 is hung on the hanging portion 13b, the front end portion of the binding band 105 can be easily passed to the back side of the hanging portion 13b, and the workability of the operation of hanging the binding band 105 on the mounting portion 13 is improved. Can be improved.
