Embodiment 1 FIG.
Hereinafter, an outdoor unit for an air-conditioning apparatus according to Embodiment 1 of the present invention will be described with reference to the drawings.

  FIG. 1 is an exploded perspective view showing an outdoor unit (hereinafter simply referred to as an outdoor unit) 100 of an air conditioner according to Embodiment 1 of the present invention. As shown in FIG. 1, a plurality of, for example, three panels, here, the front panel 1, the side panel 2, the top panel 3, and the bottom plate 25 constitute a substantially rectangular parallelepiped casing of the outdoor unit 100. Both are made of sheet metal. The front panel 1 has a substantially L-shaped horizontal cross section, and constitutes a front surface of the housing and also constitutes a side surface opposite to the side panel 2. Moreover, the heat exchanger 7 is arrange | positioned at the back side in a housing | casing. A side cover 17 is fixed to the outside of the side panel 2.

  The outdoor unit 100 has a blower chamber 4 and a machine chamber 5 inside a housing, and each chamber is divided into left and right by a partition plate 6 installed upright on a bottom plate 25. When the outdoor unit 100 is viewed from the front side, the blower chamber 4 is located on the left side, and the machine room 5 is located on the right side.

  The blower chamber 4 is provided with a heat exchanger 7 disposed on the back side and a blower fan 8 composed of a propeller fan in front of the heat exchanger 7. The heat exchanger 7 has a substantially L-shaped horizontal cross section, and is provided on the side surface and the back surface of the blower chamber 4.

  A compressor 9 and a refrigerant pipe 10 are disposed in the machine room 5. An electrical component unit 11 composed of electrical and electronic parts is installed on the partition plate 6 in the upper part of the machine room 5 and a part of the blower room 4. The electrical unit 11 performs power supply and operation control to each component of the outdoor unit 100.

  Here, as shown in FIG. 1, in the description of this embodiment, the front direction of the front panel 1 is the front side, and the opposite direction is the back side. The outdoor unit 100 is installed with its rear surface facing the outer wall of a building that performs air conditioning, and an indoor unit (not shown) is installed above the room.

  FIG. 2 is a partially exploded perspective view showing the outdoor unit 100 according to the first embodiment, and FIG. 3 is a perspective view showing the side panel 2. On the side surface on the machine room side that is one side surface of the outdoor unit 100, the valve 12 provided in the lower part is connected to the refrigerant pipe 10 in the machine room 5 on the inner side. Moreover, the terminal block unit 14 provided above the valve 12 on the side surface of the outdoor unit 100 is connected to the electrical component unit 11 via a lead wire. As shown in FIG. 3, the side panel 2 constituting the side surface of the housing has an opening 16a at the top and a notch 16b at the bottom. As shown in FIG. 2, the upper opening 16 a is a terminal block unit opening 16 a where the terminal block unit 14 can be seen, and the lower notch 16 b is a valve notch 16 b from which the valve 12 protrudes. . The outdoor unit 100 before being installed is not connected to the electrical wiring 15 and the connecting pipe 13 extending from the indoor unit side, but the side cover 17 is detachably fixed to the side panel 2.

  FIG. 4 is an explanatory view showing the periphery of the terminal block unit opening 16a of the side panel 2 in an enlarged manner. The terminal block unit 14 visible from the terminal block unit opening 16 a is configured by fixing a terminal block 22 having three terminals 21 to a fixed plate 20. The three terminals 21 are terminals of the electrical wiring of the electrical component unit 11, two are power supply terminals and the other one is a signal terminal. However, the number of terminals is not limited to three and may be more.

  When the outdoor unit 100 is installed, the tips of the three electric wires 15 extending from the indoor unit side are inserted and connected to the terminals 21 of the terminal block 22 from below. Thereby, the power supply and signal from an indoor unit can be transmitted to the electrical component unit 11.

  FIG. 5 is a side view showing the outdoor unit 100 with the side cover 17 removed. As shown in FIG. 5, the two connection pipes 13 extending from the indoor unit side are connected to the two valves 12 protruding from the valve cutouts 16b, so that the indoor unit (not shown) and the outdoor unit are connected to each other. The machine 100 is connected to the connecting pipe 13 to form a refrigerant circuit. In FIG. 5, illustration of the terminal block unit 14 is omitted. Actually, the terminal block unit 14 includes a fixed plate 20, a terminal 21, and a terminal block 22 as shown in FIG. 4.

  FIG. 6 is a perspective view showing a side cover 17 that covers the bulb 12 and the terminal block unit 14. The side cover 17 attached to the side panel 2 of the outdoor unit 100 has a hollow shape with the side facing the side panel 2 opened so as to cover the valve 12 and the terminal block unit 14, and is located on the opposite side of the open side. It has three surfaces: a side surface, a front surface, and a back surface. Although the connection pipe 13 is thicker than the electric wiring 15, the connection pipe 13 is thicker than the upper part in the lower part that covers the valve 12 connected to the connection pipe 13. That is, the lower part bulges outside the upper part.

  The open side of the side cover 17 is referred to as an edge 19, and the side cover 17 is fixed with the edge 19 in contact with the side panel 2. Here, the side cover 17 is screwed to the side panel 2 by a pair of screw fixing portions 17a. In the perspective view of FIG. 6, only one screw fixing portion 17a is shown. However, the fixing method of the side cover 17 may not be screw fixing, but may be claw fixing or other methods. It may be fixed with screws after being temporarily fixed with a nail.

On the back surface of the side cover 17, one side on the side of the edge 19 is opened, and two openings 23 and 24 are formed. The lower opening 23 is a connection pipe opening 23 through which the connection pipe 13 extending from the indoor unit side passes, and the upper opening 24 is an electric wiring opening 24 through which the electric wiring 15 extending from the indoor unit side passes. The electrical wiring opening 24 is provided above the connection piping opening 23, for example, about 50 mm above. In addition, the corner has a rounded shape. When the side cover 17 is fixed to the side panel 2, the back surface of the side cover 17 faces the outer wall of the building to be installed, like the back surface of the outdoor unit 100.

  The installation operator connects the connection pipe 13 and the electrical wiring 15 to the valve 12 and the terminal block unit 14, respectively (the state shown in FIG. 5), then the connection pipe 13 passes through the connection pipe opening 23, and The edge 19 of the side cover 17 is brought into contact with the side panel 2 so that the electrical wiring 15 passes through the electrical wiring opening 24. Then, the side cover 17 is fixed to the side panel 2 by being fixed by the screw fixing portion 17 a of the side cover 17. When the side cover 17 is fixed to the side panel 2, the terminal block unit 14 and the valve 12 are covered with the side cover 17 as shown in FIG. 7. The side cover 17 protects the terminal block unit 14 and the bulb 12 from being exposed to wind and rain and being subjected to external impacts.

  Since the rear surfaces of the outdoor unit 100 and the side cover 17 are installed facing the building wall, the connection piping opening 23 and the electrical wiring opening 24 formed on the rear surface are difficult to see from the front. 100 appearance design is not impaired.

Here, the reason why the height of the outdoor unit 100 is increased in replacement of the air conditioner will be described.
In order to increase the efficiency of the air conditioner, it is conceivable to increase the heat transfer area of the heat exchanger 7. The heat exchange amount Q of the heat exchanger 7 has the following relationship from the heat transmittance k, the heat transfer area A, and the temperature difference ΔT between the high temperature fluid and the low temperature fluid of the heat exchanger.
Q = k * A * ΔT
When the heat transfer area A increases in the above equation, the temperature difference ΔT when obtaining the same heat exchange amount Q can be reduced. For this reason, the input etc. of the air blower 8 can be reduced and it leads to high efficiency. On the other hand, the area where the outdoor outdoor unit 100 is installed cannot be increased unnecessarily. For example, the outdoor unit 100 must be installed in a confined space such as a condominium veranda. If the heat exchanger is enlarged by increasing the width and depth of the outdoor unit 100, the outdoor unit 100 cannot be installed. Things can happen. Therefore, the bottom area of the outdoor unit 100 is substantially the same, and the height of the outdoor unit 100 is increased in an attempt to increase the heat transfer area A of the heat exchanger 7 by increasing the size upward.

  The conventional side cover has a configuration in which only one opening is provided in the lower part of the back surface, and both the connection pipe 13 and the electric wiring 15 pass through the lower opening. In this embodiment, the opening through which the electric wiring 15 passes. 24 is provided at least above the connection pipe opening 23 separately from the connection pipe opening 23. For this reason, the height of the outdoor unit 100 that has been improved in efficiency as described above is increased in replacement, and the position of the terminal block unit 14 that connects the electric wiring 15 extending from the indoor unit side is far from the connection pipe opening 23. Even so, the existing electrical wiring 15 used so far can be routed through the electrical wiring opening 24 and connected to the terminal block unit 14.

  The electrical wiring 15 extending from the indoor unit side is approximately 2 times the distance between the electrical wiring opening 24 of the side cover 17 and the connection piping opening 23 as compared with the case where the connection piping 13 and the connection piping opening are passed through as in the prior art. It may be about twice as short. For example, when the electrical wiring opening 24 of the side cover 17 is provided over 50 mm above the connection piping opening 23, the electrical wiring 15 extending from the indoor unit side is connected to the terminal block unit 14 through the connection piping opening 23. It may be about 100 mm shorter than this.

  Further, since the electrical wiring 15 is inserted and connected from below the terminal 21, the electrical wiring opening 24 is preferably provided at a position below the position of the terminal 21 of the terminal block unit 14. When the side cover 17 is fixed to the side panel 2, the electrical wiring 15 inserted from below the terminal 21 can be smoothly positioned in the electrical wiring opening 24 provided below the terminal 21.

  For these reasons, the electrical wiring opening 24 of the side cover 17 is preferably provided at a position above the connection piping opening 23 and below the position of the terminal 21 of the terminal block unit 14.

  Furthermore, since both the connection piping opening 23 and the electrical wiring opening 24 of the side cover 17 are formed on the same surface, here, the back surface, the operation of fixing the side cover 17 to the side panel 2 can be made difficult. In addition, when the connecting pipe 13 and the electric wiring 15 extending from the indoor unit side that have been used up to now are traveling down the outer wall of the building (or passing through the building wall), the side surface What is necessary is just to leave the connection piping 13 and the electrical wiring 15 in the vicinity of the electrical wiring opening 24 and to connect to the valve 12 and the terminal block unit 14 respectively as it is until the electrical wiring opening 24 of the cover 17 is left as it is. Thus, the installation work can be performed relatively easily using the existing electrical wiring 15. Further, the connection pipe 13 and the electric wiring 15 are the same up to the vicinity of the opening 24 for the electric wiring, and there is no problem in appearance.

  In particular, since the surface on which the connection pipe opening 23 and the electrical wiring opening 24 are formed is provided on the back surface of the side cover 17, that is, the side facing the outer wall of the building, the connection pipe 13 extending from the indoor unit and As shown in FIG. 8, the electrical wiring 15 is connected into the outdoor unit 100 from the back side. For this reason, since the connection piping opening 23 and the electrical wiring opening 24 are difficult to see from the outside of the building, that is, from the front side of the outdoor unit 100, the appearance design of the outdoor unit 100 is not impaired.

  Further, the connection piping opening 23 and the electrical wiring opening 24 of the side cover 17 are each continuous with the edge 19 of the side cover 17 and one side is open. Therefore, in the operation of fixing the side cover 17 to the side panel 2, the connection pipe 13 is positioned on one side where the connection pipe opening 23 is opened, and the electric wiring 15 is placed on one side where the electric wiring opening 24 is opened. The side cover 17 can be easily fixed.

  The side cover 17 may be made of metal or resin. In the case of resin, a metal cover 18 that covers the terminal block unit 14 may be separately provided inside the side cover 17 as shown in FIG. By providing the metal cover 18, it is possible to prevent the fire from spreading to the outside even if a fire occurs in the electrical component unit 11 due to a short circuit or the like. When the side cover 17 is made of metal, the metal cover 18 may not be provided.

  Further, the size of the opening 24 for the electric wiring of the side cover 17 is such that the rain water and small animals (which cause a short circuit in the electric product unit 11) enter the electric wiring 15 extending from the indoor unit side. It is preferable that there is no level. The size of the connection pipe opening 23 is the same, and it is preferable that the connection pipe 13 extending from the indoor unit side is passed and the connection pipe 13 is almost closed.

Embodiment 2. FIG.
Hereinafter, the outdoor unit 200 of the air conditioner in Embodiment 2 of this invention is demonstrated using drawing. When installing the air conditioner, when the connection pipe 13 and the electric wiring 15 are newly installed, or when the length of the electric wiring 15 is sufficient even when the existing connection pipe 13 and the electric wiring 15 are used, It is not necessary to use the electrical wiring opening 24. That is, both the electrical wiring 15 and the connection pipe 13 extending from the indoor unit side may be connected to the terminal block unit 14 and the valve 12 through the connection pipe opening 23, respectively. In such a case, in the side cover 17 shown in FIG. 6, the electrical wiring opening 24 is opened without being used, and rainwater or small animals (causes a short circuit in the electrical unit 11 from the electrical wiring opening 24. There is a problem that there is a risk of intrusion.

  FIG. 10 is a perspective view showing the side cover 30 of the outdoor unit 200 according to Embodiment 2, and shows the electrical wiring opening cover 31 in an exploded manner. As in the case of the side cover 17 shown in FIG. 6, the side cover 30 is connected to the connection pipe opening 23 through which the connection pipe 13 passes, and the electrical wiring 15 passes through the connection pipe opening 23, for example, 50 mm above the connection pipe opening 23. An opening 24 is provided. In the first embodiment, the electrical wiring opening 24 of the side cover 17 is always open, but the side cover 30 of this embodiment has an electrical wiring opening cover 31 that covers the electrical wiring opening 24. . Before the outdoor unit 200 is installed, the electrical wiring opening cover 31 is fixed to the side cover 30 and the electrical wiring opening 24 is closed. The electrical wiring opening cover 31 is a separate component from the side cover 30, and may be fixed to the side cover 30 with claws or may be fixed to the side cover 30 with screws. The electrical wiring opening cover 31 may have any configuration as long as it covers the electrical wiring opening 24.

  When the outdoor pipe is installed by newly installing the connection pipe 13 and the electric wiring 15, the electric wiring 15 extending from the indoor unit side does not reach the terminal block unit 14 of the outdoor unit 200. For this reason, as shown in FIG. 11, the electrical wiring 15 is made long so as to pass through the connection pipe opening 23 provided in the lower part of the side cover 30 together with the connection pipe 13. Here, the configuration of the terminal block unit 14 is the same as that of FIG. FIG. 12 is a side view showing the side cover 30 to which the electrical wiring opening cover 31 is fixed fixed to the side panel 2.

  When the length of the electrical wiring 15 is sufficient as described above, when the side cover 30 is fixed to the side panel 2, the electrical wiring 15 extending from the indoor unit side is passed through the connection piping opening 23 together with the connection piping 13. Fix it. The connecting pipe 13 and the electrical wiring 15 are routed together from the outdoor unit side down the outer wall surface of the building (or through the inside of the building wall) and installed in a state of passing from the back side to the inside of the side cover 30. Therefore, the installation workability is good and the design of the appearance is not impaired.

  In particular, when the electrical wiring opening 24 is not used, the electrical wiring opening 24 is covered with the electrical wiring opening cover 31, so that rainwater and small animals (short circuit in the electrical unit 11) can be made from the electrical wiring opening 24. Can be prevented from entering the side cover 30, and the outdoor unit 200 is more reliable than the case where the electrical wiring opening 24 remains open.

  On the other hand, when replacing an outdoor unit that has been used before, there is an existing electrical wiring 15 and connection pipe 13, and the height of the outdoor unit 200 to be installed is higher than that of the outdoor unit that has been used so far. In this case, there is a possibility that the distance between the connection piping opening 23 and the terminal block unit 14 becomes long, and the length of the existing electrical wiring 15 becomes insufficient.

When the length of the existing electrical wiring 15 is short, the electrical wiring opening cover 31 fixed to the side cover 30 is removed, and the electrical wiring opening 24 is formed above the connection piping opening 23. The side cover 30 is fixed to the side panel 2 with the electrical wiring 15 passing through the electrical wiring opening 24. As described in the first embodiment, by providing the electrical wiring opening 24 above the connection piping opening 23, it is possible to connect to the terminal block unit 14 even if the electrical wiring 15 extending from the indoor unit side is short. Can do. Thus, when there is an existing electrical wiring 15, the electrical wiring 15 can be used effectively, and the installation workability can be improved.

  As described above, by providing the electric wiring opening cover 31 that covers and fixes the electric wiring opening 24 of the side cover 30, when the connection pipe 13 and the electric wiring 15 are newly installed, the existing connection pipe 13 and Any of the cases where the electrical wiring 15 is used and the length of the electrical wiring 15 is sufficient, the existing connection pipe 13 and the electrical wiring 15 are used, and the length of the electrical wiring 15 is short. The side cover 30 that can cope with the case is obtained.

Embodiment 3 FIG.
Hereinafter, the outdoor unit of the air conditioner in Embodiment 3 of this invention is demonstrated. The side cover according to Embodiment 3 has an opening forming portion 33 that can form the electrical wiring opening 24 when the electrical wiring opening 24 is used when the outdoor unit is installed. FIG. 13 is a perspective view showing a side cover 32 according to the third embodiment. The side cover 32 includes a connection pipe opening 23 at a lower portion thereof, and further includes an opening forming portion 33 at a position where the electrical wiring opening 24 above the connection pipe opening 23 is provided. The side cover 32 is made of resin, and the side cover 32 and the opening forming portion 33 for electric wiring are integrally formed.

  FIG. 14 is an explanatory view showing the periphery of the opening forming portion 33 provided on the back surface of the side cover 32 in an enlarged manner, and FIG. 15 shows the opening 24 for electric wiring formed by cutting the opening forming portion 33. It is a perspective view which shows the side cover 32 of a state.

  The opening forming portion 33 formed at a position where the electrical wiring opening 24 is provided has a quadrangular shape and has outer peripheries 33a, 33b, 33c, and 33d. The outer periphery 33a which is a part of the outer periphery 33a, 33b, 33c, 33d is the edge 19 on the side facing the side panel 2 of the side cover 32. Thin portions 34a, 34b, 34c (thin portions 34 in FIG. 13) are formed along the U-shaped outer peripheries 33b, 33c, 33d excluding the outer perimeter 33a. Has been. The thin portions 34 a, 34 b, 34 c are formed with a width W on the outer periphery 33 b, 33 c, 33 d of the opening forming portion 33.

  When the outdoor pipe is installed with the connection pipe 13 and the electric wiring 15 newly installed or when the existing connection pipe 13 and the electric wiring 15 are used, if the length of the electric wiring 15 is sufficient, The opening forming portion 33 is left as it is, and is used in a closed state without forming the electrical wiring opening 24. Similar to the side cover 30 of FIG. 12, the electrical wiring 15 extending from the indoor side is routed together with the connection pipe 13 through the connection pipe opening 23, and the side cover 32 is fixed to the side panel 2.

  On the other hand, in the case where the existing electrical wiring 15 is used and the length of the electrical wiring 15 is insufficient when routed through the connection piping opening 23, the electrical wiring is disposed above the connection piping opening 23. Opening 24 is formed. When installing the outdoor unit, when the opening 24 for electric wiring is required, if the installation operator cuts the thin portions 34a, 34b, 34c with a cutting tool, the opening forming portion 33 is cut out, as shown in FIG. Thus, the electrical wiring opening 24 is formed. By routing the electrical wiring 15 through the electrical wiring opening 24, the electrical wiring 15 can be connected to the terminal block unit 14 even if the length of the electrical wiring 15 is short. Thus, the installation workability can be improved by using the existing electrical wiring 15.

  Here, U-shaped outer peripheries 33b, 33c, and 33d that are cut when the electrical wiring opening 24 is formed are formed by thin portions 34a, 34b, and 34c that are thinner than other portions of the side cover 32. Therefore, if the installation operator cuts the thin portions 34 a, 34 b, 34 c of the opening forming portion 33 from the edge 19, the opening forming portion 33 can be easily cut off and the electrical wiring opening 24 is formed.

  In addition, instead of making the outer periphery 33b, 33c, 33d of the opening forming portion 33 thinner than the other portions, the portion that becomes the electrical wiring opening 24, that is, all of the opening forming portion 33 is replaced with the other portions of the side cover 32. It may be thinner. Further, the upper and lower thin portions 34a and 34c are formed, and the portions are cut and the opening forming portion 33 is not cut, that is, a part of the outer periphery of the opening forming portion 33 (the outer periphery 33c in FIG. 14) is connected.
