Description

  The present invention relates to an outdoor unit of a refrigeration apparatus.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2005-69583) discloses an outdoor unit including a switch for forced operation. The outdoor unit includes an electrical component box that accommodates a board on which various control components are provided, and a switch is provided on the board. When performing maintenance or the like of the outdoor unit, an operator or the like removes a part of the casing that covers the outside of the outdoor unit, but does the work without removing the electrical component box. When the outdoor unit is forcibly operated, the operator presses a switch on the substrate from the outside of the electrical component box using, for example, a tool. At this time, the operator presses the switch with the tool while visually confirming the relationship between the tool and the switch.

  However, as described above, the switch is provided on the substrate inside the electrical component box, and it is difficult to press the switch from the outside of the electrical component box.

  Accordingly, an object of the present invention is to provide an outdoor unit of a refrigeration apparatus having a mechanism capable of easily pushing a switch inside an electrical component box.

  An outdoor unit of a refrigeration apparatus according to a first aspect of the present invention includes a substrate, a guide member, and an electrical component casing. A switch is provided on the substrate. The guide member can be inserted with a rod-shaped member, and forms a guide space for guiding the rod-shaped member to the vicinity of the switch. The electrical component casing houses the switch and the guide member.

  According to the outdoor unit of this refrigeration apparatus, the guide member is formed along the direction of the switch from the outside direction of the electrical component casing, and guides the rod-shaped member to the vicinity of the switch. Thus, the operator can easily and accurately press the switch using the rod-shaped member. The vicinity of the switch includes not only the position of the switch itself but also a range in which the switch can be pushed in a range where the tip of the rod-shaped member guided by the guide member is movable.

  The guide member is formed of, for example, an L-shaped plate member having two surfaces and a U-shaped plate member having three surfaces. Each surface of the guide space is not limited to a plate shape, and may be a curved surface shape.

  In the outdoor unit of the refrigeration apparatus according to the second aspect of the present invention, the guide space formed by the guide member in the outdoor unit of the refrigeration apparatus according to the first aspect is cylindrical.

  Here, the cylindrical guide space efficiently guides the rod-shaped member to the vicinity of the switch. Further, the operator can grasp the insertion position of the rod-shaped member and the operation position of the switch only by looking at the cylindrical guide space.

  In the outdoor unit of the refrigeration apparatus according to the third aspect of the present invention, in the outdoor unit of the refrigeration apparatus according to the second aspect, the guide space formed by the guide member is sized so that the finger does not reach the vicinity of the switch. .

  Here, the switch provided on the substrate is formed of a non-insulating member, and it is dangerous to touch the switch with a finger without using the insulating member. Therefore, even if the operator inserts a finger, the guide space of the guide member has such a size that the finger does not reach the vicinity of the switch. Alternatively, it is more preferable that the size of the guide space of the guide member is such that a finger cannot be inserted in the first place.

  In the outdoor unit of the refrigeration apparatus according to the fourth aspect of the present invention, in the outdoor unit of the refrigeration apparatus according to the third aspect, the guide member has a narrower guide space as it approaches the vicinity of the switch.

  According to this configuration, since the guide member becomes narrower as it approaches the vicinity of the switch, the rod-shaped member is automatically guided to the vicinity of the switch along the guide member. Therefore, the operator can easily operate the switch with the rod-shaped member.

  The outdoor unit of the refrigeration apparatus according to the fifth aspect of the present invention is the outdoor unit of the refrigeration apparatus according to the third aspect, wherein the guide member has an opening facing the switch. Through this opening, the tip of the rod-shaped member and the switch can contact each other.

  According to this configuration, the operator can operate the switch through the opening by moving the rod-shaped member after the guide member brings the tip of the rod-shaped member close to the vicinity of the switch.

  The outdoor unit of the refrigeration apparatus according to the sixth aspect of the present invention is the outdoor unit of the refrigeration apparatus according to the third aspect. ing.

  According to this configuration, for example, when the operator inserts and operates the rod-shaped member into the guide member, the tip of the rod-shaped member pushes the movable member of the guide member in the direction of the switch.

  In the outdoor unit of the refrigeration apparatus according to the seventh aspect of the present invention, in the outdoor unit of the refrigeration apparatus according to the sixth aspect, the movable member moves as the bar-shaped member approaches the vicinity of the switch and contacts the switch. .

  According to this configuration, as the rod-shaped member is inserted into the guide member, the rod-shaped member pushes the movable member, and the movable member moves in a direction in contact with the switch. Therefore, the operator can easily push the switch by simply inserting the rod-shaped member along the guide member.

  In the outdoor unit of the refrigeration apparatus according to the eighth aspect of the present invention, the movable member is an elastically deformable member in the outdoor unit of the refrigeration apparatus according to the sixth aspect.

  According to this configuration, the switch can be pushed by elastically deforming the movable member by the pushing force from the rod-like member.

  In the outdoor unit of the refrigeration apparatus according to the first aspect of the present invention, the guide member is formed along the direction of the switch from the outside direction of the electrical component casing, and guides the rod-shaped member to the vicinity of the switch. Thus, the operator can easily and accurately press the switch using the rod-shaped member.

  In the outdoor unit of the refrigeration apparatus according to the second aspect of the present invention, the cylindrical guide space efficiently guides the rod-shaped member to the vicinity of the switch. Further, the operator can grasp the insertion position of the rod-shaped member and the operation position of the switch only by looking at the cylindrical guide space.

  In the outdoor unit of the refrigeration apparatus according to the third aspect of the present invention, since the finger does not reach the vicinity of the switch, the risk of contact with the switch that is a non-insulating member is reduced.

  In the outdoor unit of the refrigeration apparatus according to the fourth aspect of the present invention, since the guide member becomes narrower as it approaches the vicinity of the switch, the bar-shaped member is automatically guided to the vicinity of the switch along the guide member. Therefore, the operator can easily operate the switch with the rod-shaped member.

  In the outdoor unit of the refrigeration apparatus according to the fifth aspect of the present invention, the operator can operate the switch through the opening by moving the rod-shaped member after the guide member brings the tip of the rod-shaped member close to the vicinity of the switch. .

  In the outdoor unit of the refrigeration apparatus according to the sixth aspect of the present invention, when the operator inserts and operates the rod-shaped member into the guide member, the tip of the rod-shaped member pushes the movable member of the guide member in the direction of the switch.

  In the outdoor unit of the refrigeration apparatus according to the seventh aspect of the present invention, as the rod-shaped member is inserted into the guide member, the rod-shaped member pushes the movable member, and the movable member moves in a direction in contact with the switch. Therefore, the operator can easily push the switch by simply inserting the rod-shaped member along the guide member.

The third side surface 51d is provided with a side surface opening 51f, and a heat sink (not shown) is disposed. The heat sink is a member for releasing heat generated during operation of the inverter control element or the like to the outside, and is composed of an aluminum plate, a copper plate, or the like, and has a large number of heat transfer fins. The heat sink is fitted into the side opening 51f so as to protrude from the back surface of the control board 54 toward the blower chamber S2. The heat transfer fins are in contact with the electronic component 55 on the control board 54 and release heat generated from the electronic component 55 to the blower chamber S2. The first side surface 51b and the second side surface 51c are side surfaces that cover the left side and the right side of the control board 54, respectively. The upper surface 51a, the first side surface 51b, the second side surface 51c, the third side surface 51d, and the bottom surface 51e form a box shape as shown in FIG. 3, thereby forming a space for accommodating the control board 54.

  The electrical component casing 51 includes a guide member 52 into which a driver 70 (see FIG. 7) that is a rod-like member can be inserted.

(2-2) Terminal Block Unit FIG. 5 is an explanatory diagram of the terminal block unit, where (a) is a front view, (b) is a right side view, and (c) is a top view. The terminal block unit 53 is attached to the right front surface of the electrical component casing 51. The terminal block unit 53 includes a terminal block opening 53a, a terminal block right side wall 53b, a terminal block left side wall 53c, a terminal block 53d (see FIG. 3), and a terminal block rear surface portion 53e. The terminal block opening 53a is formed by cutting the terminal block right side wall 53b from the flat surface portion 53e-1 of the terminal block rear surface portion 53e. The operator inserts a driver 70 or the like into a guide member 52 described later through the terminal block opening 53a, and operates the forced operation switch 55c. The terminal block right side wall 53b and the terminal block left side wall 53c protrude from the flat surface portion 53e-1 of the terminal block rear surface portion 53e, and are formed so as to cover the right side and the left side of the terminal block 53d. The terminal block 53d is composed of terminal parts to which wiring for transmitting data transmitted / received to / from the indoor unit is connected.

  The terminal block back surface portion 53e has a flat surface portion 53e-1 and a protruding portion 53e-2. The flat portion 53e-1 is connected to the base portions of the terminal block right side wall 53b and the terminal block left side wall 53c. The protruding portion 53e-2 protrudes from the flat surface portion 53e-1 to the back surface opposite to the front surface on which the terminal block 53d is provided. The terminal block rear surface portion 53e is connected to the upper surface 51a and the second side surface 51c of the electrical component casing 51 via screws.

(2-3) Control Board The control board 54 is introduced into the internal space of the electrical component casing 51 through the opening on the front surface of the electrical component casing 51, and the back surface thereof is the third side surface of the electrical component casing 51 as shown in FIG. It arrange | positions so that 51d may be opposed. Therefore, the control board 54 has a plate-like surface arranged in a direction perpendicular to the top plate 10 and the bottom plate 12. On the control board 54, electronic components 55 such as a microcomputer, a resistor, a reactor 55a, a capacitor 55b, and a forced operation switch 55c (see FIG. 6) are arranged. The reactor 55a constitutes a rectifier circuit of a motor that drives the compressor 40 and the like. The forced operation switch 55c is a switch for forcibly operating the refrigeration apparatus including the outdoor unit 100. Since the forced operation switch 55 c is placed on the control board 54, it is located away from the opening on the front surface of the electrical component casing 51. The forced operation switch 55c is operated by an operator inserting a driver 70 or the like into a guide member 52 described later.

(2-4) Guide Member FIG. 6 is an explanatory diagram of the guide member. FIG. 7 is a perspective view of the guide member showing how the driver is inserted into the guide member. FIG. 8 is a cross-sectional view of the guide member taken along line AA in FIG.

(A) Outline of Guide Member As shown in FIGS. 3 and 6 to 8, the guide member 52 is formed on the second side surface 51 c of the electrical component casing 51. The guide member 52 has a first surface 52a that is an upper surface, a second surface 52b that is a side surface, a third surface 52c that is a lower surface, and a fourth surface 52d that is a rear surface. The second surface 52 b is a surface on the control board 54 side in the electrical component casing 51. The 1st surface 52a and the 3rd surface 52c are surfaces formed by bending with respect to the 2nd surface 52b, and the cross-sectional shape of the 1st-3rd surfaces 52a-52c has a U-shape. The first to fourth surfaces 52a to 52d are attached to the second side surface 51c of the electrical component casing 51 to form a guide space G (see FIG. 6). Thus, the guide space G is formed in a cylindrical shape surrounded by the first to fourth surfaces 52a to 52d and the second side surface 51c. The operator inserts the driver 70 into the cylindrical guide member 52 and operates the driver 70 to control ON / OFF of the forced operation switch 55c.

  Since the guide space G is cylindrical, the driver 70 is efficiently guided to the vicinity of the forced operation switch 55c. Further, the operator can grasp the insertion position of the driver 70 and the operation position of the forced operation switch 55c only by looking at the cylindrical guide space G.

(B) Movable member The second surface 52b of the guide member 52 is provided with a movable member 52e that is movable in accordance with the movement of the driver 70 and that can contact the forced operation switch 55c. The movable member 52e is formed by cutting the second surface 52b into a U-shape, for example. The notch is formed so that the U-shaped closed portion is positioned on the back side of the guide space G and the U-shaped opening is positioned in front of the guide space G. The portion opened in a U-shape is continuous with the plane of the movable member 52e. When the operator inserts the driver 70 into the back of the guide member 52 and presses the movable member 52e, the portion separated from the second surface 52d starting from one end of the movable member 52e continuous with the second surface 52b. Lifts up. A protrusion 52f is provided at a portion of the movable member 52e facing the forced operation switch 55c. Therefore, when the operator operates the movable member 52e, the protrusion 52f turns the forced operation switch 55c on or off.

  The movable member 52e is preferably formed of an elastically deformable member. When the operator operates the driver, the movable member 52e is easily deformed in response to the pressure from the driver 70. Therefore, the forced operation switch 55c can be easily pushed by the movable member 52e.

  In the above description, the movable member 52e is formed in series with the second surface 52b by cutting the second surface 52b. However, the movable member 52e may be formed separately from the second surface 52b. For example, an opening may be formed in the second surface 52b corresponding to the position where the movable member 52e is provided, and a separately formed movable member 52e may be attached to the opening.

(C) Size of Guide Space G The guide space G formed by the guide member 52 only needs to be formed in a size that allows the driver 70 and the like to be inserted as shown in FIG. Further, it is preferable that the guide space G is formed in such a size that the finger does not reach the vicinity of the forced operation switch 55c even if the operator inserts the finger. Alternatively, it is more preferable that the guide space G is formed in such a size that the driver 70 or the like can be inserted but a finger cannot be inserted. The forced operation switch 55c provided on the control board 54 is formed of a non-insulating member, and it is dangerous to touch the forced operation switch 55c with a finger without using an insulating member. As described above, if the guide member 52 is formed in such a size that the finger does not enter or the size that the finger does not reach to the vicinity of the forced operation switch 55c, there is no risk of touching the forced operation switch 55c with the finger.

(D) Shape of the guide space G Moreover, it is preferable that the guide space G of the guide member 52 becomes narrower as it approaches the vicinity of the forced operation switch 55c. Here, as shown in FIGS. 6 and 8, the second side surface 51 c of the electrical component casing 51 forms one surface of the guide space G. The second side surface 51c is inclined with respect to the second surface 52b of the guide member 52 so as to narrow the guide space G toward the back side. The forced operation switch 55 c is formed on the control board 54 and is located on the back side of the electrical component casing 51. Since the guide space G is formed so as to narrow toward the back side, the driver 70 inserted into the guide space G approaches the vicinity of the forced operation switch 55 c disposed on the back side of the electrical component casing 51. Guided.

  FIG. 9 is a cross-sectional view showing a state where the driver is inserted into the guide space G. FIG. When the operator operates the forced operation switch 55c, the operator inserts the driver 70 into the guide member 52 from the terminal block opening 53a of the terminal block unit 53 shown in FIG. Since the guide space G becomes narrower as it approaches the vicinity of the forced operation switch 55 c, the driver 70 automatically moves in the vicinity of the forced operation switch 55 c along the guide member 52 as the operator inserts the driver 70 in the back side. Led to. Further, as the driver 70 is inserted into the back side, as shown in FIG. 9, the driver 70 pushes the movable member 52e toward the forced operation switch 55c. Therefore, the operator can easily operate the forced operation switch 55c simply by inserting the driver 70 along the guide member 52.

  The method of narrowing the guide space G toward the back side is not limited to inclining the second side surface 51c of the electrical component casing 51, and is narrowed by inclining the first to third surfaces 52a to 52c. May be. Further, by providing a separate member in the guide space G, the guide space G may be narrowed toward the back side.

(E) Method of Forming Guide Member The guide member 52 is formed by attaching the first to fourth surfaces 52 a to 52 d to the second side surface 51 c of the electrical component casing 51. That is, the first to fourth surfaces 52 a to 52 d of the guide member 52 and the electrical component casing 51 are formed separately, and the first to fourth surfaces 52 a to 52 d are attached to the electrical component casing 51. However, the guide member 52 may be formed integrally with the electrical component casing 51. That is, the first to fourth surfaces 52a to 52d of the guide member 52 and the third side surface 51c of the electrical component casing 51 may be integrally formed in a series.

(F) Action and Effect of Guide Member The guide member 52 is formed from the outer side of the electrical component casing 51 along the direction of the switch, and guides a rod-like member such as the driver 70 to the vicinity of the forced operation switch 55c. Therefore, the operator can push the forced operation switch 55c easily and accurately using the driver 70 or the like.

  As a method of facilitating the operation of the forced operation switch 55c, there is a method of providing another board at a position near the outside of the electrical component casing 51 and arranging the switch on the board. However, according to the above configuration, there is no need to change the position of the forced operation switch 55c from the control board 54 to another position. Therefore, since the forced operation switch 55c can be easily and accurately operated while maintaining the existing configuration, an increase in cost due to the addition of a separate configuration and a change in the configuration can be suppressed.

(3) Features (3-1)
When the refrigeration apparatus is forcibly operated, the operator presses the forcible operation switch 55c on the control board 54 from the outside of the electrical component box 50 using, for example, a tool or the like. At this time, the operator inserts a rod-shaped member such as the driver 70 into the guide member 52. The guide member 52 is formed along the direction of the forced operation switch 55c from the outer side of the electrical component casing 51, and guides the rod-shaped member to the vicinity of the forced operation switch 55c. Therefore, the operator can push the forced operation switch 55c easily and accurately using the rod-shaped member. The vicinity of the forced operation switch 55c includes not only the position of the forced operation switch 55c itself but also a range in which the forced operation switch 55c can be pushed in a range where the tip of the rod-shaped member guided by the guide member 52 is movable. .

  Further, according to the above configuration, the forced operation switch 55c is arranged such that another substrate is provided near the outside of the electrical component casing and the forced operation switch 55c is disposed on the substrate in order to facilitate the operation of the forced operation switch 55c. There is no need to change the arrangement of 55c. Therefore, since the forced operation switch 55c can be easily and accurately operated while maintaining the existing configuration, an increase in cost due to the addition of a separate configuration and a change in the configuration can be suppressed.

  The guide member 52 is formed of, for example, an L-shaped plate member having two surfaces and a U-shaped plate member having three surfaces. Further, each surface of the guide space G is not limited to a plate shape, and may be a curved surface shape.

(3-2)
The guide space formed by the guide member 52 is cylindrical.

  The cylindrical guide space G efficiently guides the rod-shaped member to the vicinity of the forced operation switch 55c. Further, the operator can grasp the insertion position of the rod-shaped member and the operation position of the forced operation switch 55c only by looking at the cylindrical guide space G.

(3-3)
The guide space G formed by the guide member 52 has such a size that the finger does not reach the vicinity of the forced operation switch 55c.

  The forced operation switch 55c provided on the control board 54 is formed of a non-insulating member, and it is dangerous to touch the forced operation switch 55c with a finger without using an insulating member. Therefore, even if the operator inserts a finger, the guide space G of the guide member 52 has such a size that the finger does not reach the vicinity of the forced operation switch 55c. Alternatively, it is more preferable that the size of the guide space G of the guide member 52 is such that the finger cannot be inserted in the first place.

(3-4)
As the guide member 52 approaches the vicinity of the forced operation switch 55c, the guide space G becomes narrower.

  Since the guide member 52 becomes narrower as it approaches the vicinity of the forced operation switch 55 c, the rod-shaped member is automatically guided to the vicinity of the forced operation switch 55 c along the guide member 52. Therefore, the operator can easily operate the forced operation switch 55c with the rod-shaped member.

(3-5)
The guide member 52 has an opening facing the forced operation switch 55c. The tip of the rod-shaped member and the forced operation switch 55c can be in contact with each other through this opening.

  The operator can operate the forced operation switch 55c through the opening by moving the rod-shaped member after the guide member 52 brings the tip of the rod-shaped member close to the vicinity of the forced operation switch 55c.

(3-6)
The guide member 52 has a movable member 52e that can move according to the movement of the rod-shaped member and can come into contact with the forced operation switch 55c.

  For example, when the operator inserts and operates the rod-shaped member into the guide member 52, the tip of the rod-shaped member pushes the movable member 52e of the guide member 52 in the direction of the forced operation switch 55c.

(3-7)
The movable member 52e moves as the rod-shaped member approaches the vicinity of the forced operation switch 55c, and contacts the forced operation switch 55c.

  As the rod-shaped member is inserted into the guide member 52, the rod-shaped member pushes the movable member 52e, and the movable member 52e moves in a direction in contact with the forcible operation switch 55c. Therefore, the operator can easily push the forced operation switch 55c only by inserting the rod-shaped member along the guide member 52.

(3-8)
The movable member 52e is an elastically deformable member. The forced operation switch 55c can be pushed by elastically deforming the movable member 52e with the pushing force from the rod-like member.

(4) Modification (4-1) Modification 1A
In the above embodiment, the movable member 52e is provided on the second surface 52b of the guide member 52. However, the opening 52g may be provided in the second surface 52b. FIG. 10 is a perspective view showing a modified example 1A of the guide member. The opening 52g is provided in the vicinity of the forced operation switch 55c. The operator inserts the driver 70 into the guide member 52 and moves the driver 70 to the forced operation switch 55c side. The forcible operation switch 55c can be turned on or off by the tip of the driver 70 pushing the forcible operation switch 55c through the opening 52g.

(4-2) Modification 1B
In the above embodiment, the guide member 52 is formed by attaching the first to fourth surfaces 52 a to 52 d to the second side surface 51 c of the electrical component casing 51. However, the guide member 52 may be formed of a first surface 52a that is an upper surface, a third surface 52c that is a lower surface, and a fourth surface 52d that is a rear surface. FIG. 11 is a perspective view showing a modified example 1B of the guide member. The guide member 52 in FIG. 11 does not have a surface on the control board 54 side. The operator inserts the driver 70 along the first surface 52 a, the third surface 52 c, and the second side surface 51 c of the electrical component casing 51. When the operator moves the driver 70 toward the forced operation switch 55 c, the forced operation switch 55 c can be turned on or off by the tip of the driver 70.

  FIG. 12 is a perspective view showing another example of the modification 1B of the guide member. The guide member 52 in FIG. 12 does not have the first surface 52a as compared with the guide member 52 in FIG. 11, and has only the third surface 52c and the fourth surface 52d. Therefore, the operator inserts the driver 70 along the third surface 52c and the third side surface 51c of the electrical component casing 51, and operates the forced operation switch 55c.

  In addition, when the 3rd side surface 51c of the electrical component casing 51 serves as the 4th surface 52d of the guide member 52, the 4th surface 52d can also be abbreviate | omitted.

(4-3) Modification 1C
In the said embodiment, the 1st side 51b of the electrical equipment casing 51 which forms a part of guide space G has a shape which narrows stepwise toward the back side, as shown in FIG. However, the shape is not limited to a staircase shape as long as the guide space G becomes narrower toward the back side. FIG. 13 is another example of an AA cross-sectional view of the guide space G in FIG. As shown in FIG. 13, the second side surface 51 c may have a shape that narrows toward the far side so as to form a slope.

(4-4) Modification 1D
In the above embodiment, the guide member 52 is formed by a plate-like surface. However, each surface forming the guide member 52 is not limited to a plate shape, and may be a curved surface shape.

(4-5) Modification 1E
In the above embodiment, the guide member 52 is provided only for the operation of the forced operation switch 55c. However, the switch provided with the guide member 52 is not limited to the forced operation switch 55c, and the guide member 52 can be applied to any switch. In particular, it is preferable to provide the guide member 52 for the switch that reduces the efficiency of installation work and maintenance work of the refrigeration apparatus.

  As described above, according to the present invention, it is possible to provide a mechanism that can easily push the switch inside the electrical component box, and therefore it can be applied to any refrigeration apparatus provided with a switch.
