Then, as shown in fig. 2, the electrical box 40 is disposed in the main unit 30 such that the front cover portions 43A of the first cover 42 and the second cover 43 face the front surface side of the indoor unit 100. In a state where the electrical box 40 is disposed in the indoor unit 100, the first terminal block 51 is positioned on the first floor in the front-rear direction of the indoor unit. The second terminal block 52, the third terminal block 53, and the first board unit 61 are located on the Z-direction positive side of the first terminal block 51, i.e., on the second floor in the front-rear direction of the indoor unit 100. The electronic component of the second substrate unit 62 is located on the negative side in the Z direction with respect to the first terminal table 51 of the first layer. In other words, the layers in which the second terminal table 52, the third terminal table 53, and the first substrate unit 61 are located, the layer in which the first terminal table 51 is located, and the region in which the electronic component of the second substrate unit 62 is located are layered from the positive side to the negative side in the Z direction.
As shown in fig. 5, a cutout 43C is formed in the front surface cover portion 43A of the second cover 43. When the first cover 42 is removed in a state where the second cover 43 is attached, the dial 61B of the first substrate unit 61 is exposed in the notch 43C.
Fig. 7 is a front view showing a state in which a part of components of an electrical box according to embodiment 1 of the present invention is removed. Fig. 7 shows the electrical box 40 with the first cover 42 and the second cover 43 removed. The first terminal block 51 is disposed so that the wiring connection portion 51A faces the side on which the front cover portions 43A of the first cover 42 and the second cover 43 are mounted. The second terminal block 52 is disposed so that the wiring connection portion 52A faces the side where the front cover portions 43A of the first cover 42 and the second cover 43 are attached. The third terminal base 53 is disposed so that the wiring connection portion 53A faces the side on which the front cover portion 43A of the first cover 42 and the second cover 43 are mounted. The first substrate unit 61 is disposed such that the substrate surface of the substrate 61A faces the side on which the front surface cover portions 43A of the first cover 42 and the second cover 43 are mounted. Further, the first terminal table 51, the second terminal table 52, the third terminal table 53, and the first substrate unit 61 are arranged such that the wiring connection portion 51A, the wiring connection portion 52A, the wiring connection portion 53A, and the dial 61B do not overlap when viewed from the first cover 42 and the front cover portion 43A side.
The setting work performed by the operator on site when installing the indoor unit 100 will be described. Fig. 8 is a perspective view of the indoor unit 100 when the setting operation is started at the site. Fig. 9 is an enlarged view of the right end of the indoor unit 100 in the state of fig. 8. Fig. 10 is a view showing the inside of the indoor unit 100 from the direction of the arrow by cutting the indoor unit at the position of line a-a in fig. 9. Fig. 11 is an enlarged view of the right end of the indoor unit 100 after the on-site operation. Fig. 12 is a view showing the inside of the indoor unit 100 from the direction of the arrow by cutting the indoor unit at the position of line B-B in fig. 11. In fig. 12, the cables and the wires are illustrated in black in order to clearly show the internal state of the electrical box 40.
The grill 10 is opened and the service panel 31 is removed. As shown in fig. 8, a panel opening 20A is formed at the right end of the panel 20. When the grill 10 is opened, the panel opening 20A of the panel 20 is exposed. Further, the first cover 42 of the electrical box 40 is removed. As described above, the electrical box 40 is disposed at a position corresponding to the panel opening 20A. Therefore, when the first cover 42 is removed, the inside of the electrical box 40 is exposed through the panel opening 20A as shown in fig. 9.
As described with reference to fig. 7, the first terminal block 51 is disposed so that the wiring connection portion 51A faces the side on which the front cover portions 43A of the first cover 42 and the second cover 43 are mounted. The second terminal block 52 is disposed so that the wiring connection portion 52A faces the side where the front cover portions 43A of the first cover 42 and the second cover 43 are attached. The third terminal base 53 is disposed so that the wiring connection portion 53A faces the side on which the front cover portion 43A of the first cover 42 and the second cover 43 are mounted. The first substrate unit 61 is disposed such that the substrate surface of the substrate 61A faces the side on which the front surface cover portions 43A of the first cover 42 and the second cover 43 are mounted. Therefore, as shown in fig. 9, the wiring connection portion 51A, the wiring connection portion 52A, the wiring connection portion 53A, and the dial 61B face the panel opening portion 20A side.
As described with reference to fig. 7, the wiring connection portion 51A, the wiring connection portion 52A, the wiring connection portion 53A, and the dial 61B are arranged so as not to overlap when viewed from the front cover portion 43A side of the first cover 42 and the second cover 43. Therefore, as shown in fig. 9, the wiring connection portion 51A, the wiring connection portion 52A, the wiring connection portion 53A, and the dial 61B can be visually confirmed without being blocked by other members when viewed from the front through the panel opening portion 20A.
As described above, the substrate of the second substrate unit 62 is disposed along the side surface cover portion 43B of the second cover 43 in the electrical box 40. Therefore, the substrate of the second substrate unit 62 is located at a position separated from the panel opening 20A than the first substrate unit 61, the first terminal stand 51, the second terminal stand 52, and the third terminal stand 53. The electronic component of the second substrate unit 62 is located on the negative side in the Z direction with respect to the first terminal table 51. In this manner, the second substrate unit 62 is disposed so that the mounted electronic components do not protrude from the panel opening 20A.
An insertion port 80 is formed in a lower portion of the rear surface side of the electrical box 40. The insertion port 80 opens to the rear side of the indoor unit 100, i.e., the negative side in the Z direction, at the lower portion of the electrical box 40. The insertion port 80 is exposed by removing the service panel 31. The cable guide 44 has a shape in which a plurality of surfaces extending along the Z-direction positive side and a plurality of surfaces extending along the Y-direction positive side are combined from the end 44A on the insertion port 80 side toward the end 44B on the front surface side of the indoor unit 100.
The operator inserts a cable, which is formed by bundling wires connected to the wiring connection portion 51A of the first terminal block 51, through the insertion port 80. The operator performs the same operation for the cable in which the wires connected to the wire connection portion 52A of the second terminal block 52 are bundled and the cable in which the wires connected to the wire connection portion 53A of the third terminal block 53 are bundled. Then, the operator pushes the cable toward the front surface side of the indoor unit 100, that is, the positive side in the Z direction. Thus, the cable is guided by the cable guide 44, and the distal end portion reaches the panel opening portion 20A.
The operator performs an operation of connecting the corresponding wires to the wiring connection portion 51A of the first terminal block 51, the wiring connection portion 52A of the second terminal block 52, and the wiring connection portion 53A of the third terminal block 53 through the panel opening 20A. As a result, as shown in fig. 11, the wiring bundled as the cable 151 is connected to the wiring connection unit 51A, the wiring bundled as the cable 152 is connected to the wiring connection unit 52A, and the wiring bundled as the cable 153 is connected to the wiring connection unit 52A. As described above, the cable 151 is a communication cable, the cable 152 is a power supply cable, and the cable 153 is a remote controller cable. As described above, in embodiment 1, the panel opening 20A functions as a terminal block connection space.
Further, the operator performs the switch setting operation by appropriately operating the dial 61B of the first substrate unit 61 through the panel opening portion 20A, and performs the address setting of the indoor unit 100.
In embodiment 1, the first terminal table 51, the second terminal table 52, the third terminal table 53, and the first substrate unit 61 are arranged in a layered manner. The wiring connection portion 51A, the wiring connection portion 52A, the wiring connection portion 53A, and the dial 61B are arranged so as not to overlap when viewed from the front through the panel opening portion 20A. Therefore, when performing the wiring connection work of each of the wiring connection portion 51A, the wiring connection portion 52A, and the wiring connection portion 53A, the operator does not need to remove the other terminal block and the first substrate unit 61. In addition, the operator does not need to remove the first terminal table 51, the second terminal table 52, and the third terminal table 53 when operating the dial 61B of the first substrate unit 61. Therefore, according to embodiment 1, the electrical box 40 can be downsized, and the workability of wiring connection and the workability of switch setting when installing the indoor unit 100 can be improved.
A cutout 43C is formed in the front cover portion 43A of the second cover 43, and when the first cover 42 is removed, the dial 61B of the first substrate unit 61 is exposed. Therefore, the operator can operate the dial 61B through the panel opening portion 20A without removing the second cover 43. That is, according to embodiment 1, the workability of the switch setting when installing the indoor unit 100 is further improved.
The first substrate unit 61 is fixed to the front surface side of the first terminal table 51 by a fixing member 70. According to this configuration, a space corresponding to the thickness of the fixing member 70 is formed between the first substrate unit 61 and the first terminal block 51. Therefore, even after the operation of connecting the wiring to the wiring connection portion 51A of the first terminal block 51 is performed, the setting operation of the dial 61B by the operator is not hindered by the wiring or the cable. That is, according to embodiment 1, the switch setting work space is secured when the indoor unit 100 is installed, and the workability of the switch setting can be further improved.
The second substrate unit 62 is disposed so that the mounted electronic components do not protrude from the panel opening 20A. In other words, in embodiment 1, the only configuration in which the interior of the electrical box 40 is exposed through the panel opening 20A when the first cover 42 is removed is that components which require the above-described work to be performed on site when the indoor unit 100 is installed. Therefore, workability is improved with a minimum space required for the panel opening 20A.
Further, the operator can easily position the end portion of the cable 151, the end portion of the cable 152, and the end portion of the cable 153 in the operable area through the panel opening portion 20A by using the cable guide 44. Can be guided. According to embodiment 1, the workability of wiring connection when installing the indoor unit 100 can be further improved.
Further, a communication line connected to the outdoor unit is connected to the wiring connection portion 51A of the first terminal block 51 positioned on the Z-direction negative side of the first substrate unit 61. Therefore, the voltage level of the wiring connection portion 51A is lower than that of the wiring connection portion 52A of the second terminal block 52 connected to the power supply line. The voltage level is low. As described above, in embodiment 1, since the low-voltage terminal block is disposed below the first substrate unit 61, the electrical safety of the electrical box 40 and the indoor unit 100 can be improved.
In embodiment 1, two substrate units and three terminal blocks are housed in the electrical box 40, but the present invention is not limited to this.
Embodiment 2.
Fig. 13 is a diagram showing an example of the configuration of an air conditioner according to embodiment 2 of the present invention. In embodiment 2, the air conditioner 1 is shown as an example of a refrigeration cycle apparatus. In fig. 13, the same operations are performed with respect to the components described in embodiment 1 using fig. 1 to 12. The air conditioner 1 includes the outdoor unit 200 and the indoor unit 100 described in embodiment 1. The outdoor unit 200 and the indoor unit 100 are connected by a gas refrigerant pipe 300 and a liquid refrigerant pipe 400. The outdoor unit 200 includes a compressor 210, a four-way valve 220, an outdoor heat exchanger 230, and an expansion valve 240.
The compressor 210 compresses and discharges the sucked refrigerant. The compressor 210 changes the capacity of the compressor 210, that is, the amount of refrigerant sent per unit time, by changing the operating frequency arbitrarily, for example, by an inverter circuit or the like. The four-way valve 220 is a valve for switching the flow of the refrigerant between the cooling operation and the heating operation. In fig. 13, solid arrows indicate the flow of the refrigerant during the cooling operation, and broken arrows indicate the flow of the refrigerant during the heating operation.
The outdoor heat exchanger 230 in embodiment 2 exchanges heat between the refrigerant and the outdoor air. The outdoor heat exchanger 230 functions as an evaporator during the heating operation, and evaporates and gasifies the refrigerant. The outdoor heat exchanger 230 functions as a condenser during the cooling operation, and condenses and liquefies the refrigerant.
The expansion valve 240 decompresses and expands the refrigerant. When the expansion valve 240 is configured by, for example, an electronic expansion valve, the opening degree of the expansion valve 240 is adjusted based on an instruction from a control device, not shown. The indoor heat exchanger 110 performs heat exchange between air to be air-conditioned and a refrigerant. The indoor heat exchanger 110 functions as a condenser during the heating operation, and condenses and liquefies the refrigerant. The indoor heat exchanger 110 functions as an evaporator during the cooling operation, and evaporates and gasifies the refrigerant.
As described above, the air conditioner 1 is configured to switch the flow of the refrigerant by the four-way valve 220 of the outdoor unit 200, thereby realizing the heating operation and the cooling operation.
