Therefore, the control box serves as a resistance of the air passage for the air sucked from the air inlet by the fan. When the resistance of the air passage is increased in the indoor unit for the air-conditioning apparatus, it is necessary to increase an amount of air sent by a fan by an amount corresponding to increase in resistance.
[0006] The present disclosure has been made in view of the above-described circumstances, and an object of the present disclosure is to provide an indoor unit for an air-conditioning apparatus that can reduce an amount of air sent by a fan by reducing an air-passage resistance caused by a control box.
Solution to Problem [0007] An indoor unit for an air-conditioning apparatus according to an embodiment of the present disclosure includes: a housing having a cuboid shape, and including an air inlet on one of side surfaces and an air outlet on an other side surface opposed to the one side surface; a fan case including a fan case air inlet from which air from the air inlet of the housing is sucked, and a fan case air outlet from which the air sucked from the fan case air inlet is blown out toward the air outlet; a fan housed in the fan case, and configured to suck the air from the air inlet of the housing from the fan case air inlet and to send the sucked air from the fan case air outlet to the air outlet through an opening port of a partition plate; a heat exchanger housed in the housing; the partition plate disposed between the fan case and the heat exchanger, and including the opening port at a position corresponding to the fan case air outlet of the fan case; and a control box including a controller configured to control the fan, the control box being disposed on a downstream of the fan case air inlet in a flow of the air and in a portion other than an area that connects the fan case air outlet to the opening port of the partition plate in a longitudinal direction and a horizontal direction of the housing. Advantageous Effects of Invention [0008] According to the embodiment of the present disclosure, the control box is disposed on the downstream of the fan case air inlet in the flow of the air and in the portion other than the area that connects the fan case air outlet to the opening port of the partition plate in the longitudinal direction and the horizontal direction of the housing. At such a position, the flow of the air is gentle as compared with a position on an upstream of the fan case. Therefore, it is possible to reduce the air-passage resistance caused by the control box in the housing of the indoor unit, and to reduce the amount of air sent by the fan.

An evaporator, an expansion valve as an expansion unit, an unillustrated compressor, a four-way valve, and a condenser of the indoor unit are disposed outside the indoor unit, and are sequentially connected by refrigerant pipes to configure a refrigerant circuit.
[0012] Fig. 1 is a diagram explaining an arrangement configuration of a control box 6 and other components of an indoor unit 100 for an air-conditioning apparatus according to Embodiment 1.
[0013] As illustrated in Fig. 1, a housing 1 of the indoor unit 100 according to Embodiment 1 includes an air inlet 2, an air outlet 3, a heat exchanger 4, a partition plate 5, a control box 6, a first fan case 7a, and a second fan case 7b.
[0014] The housing 1 has a cuboid shape. The air inlet 2 for the air outside the housing 1 is provided on a left side surface of the housing 1 as viewed from a front surface side. Further, the air outlet 3 is provided on a right side surface of the housing 1.
[0015] The air sucked from the air inlet 2 is sent toward the right side surface by a first fan 9a housed in the first fan case 7a and a second fan 9b housed in the second fan case 7b. The sent air passes through the partition plate 5 and the heat exchanger 4, and is blown out from the air outlet 3. In other words, as illustrated by arrows in Fig. 1, the air that has been sucked from the air inlet 2 provided on the left side surface of the housing 1 and has been heat-exchanged by the heat exchanger 4 is blown out from the air outlet 3 provided on the right side surface of the housing 1.
[0016] The first fan case 7a and the second fan case 7b are disposed in the housing 1. The first fan case 7a and the second fan case 7b are disposed with a predetermined interval in a transverse direction of the housing 1, inside the housing 1.
[0017] A first fan case air inlet 10a is provided on a front surface of the first fan case 7a. The first fan case air inlet 10a is for sucking the air sucked from the air inlet 2 into the first fan case 7a.
[0018] A second fan case air inlet 10b is provided on a front surface of the second fan case 7b. The second fan case air inlet 10b is for sucking the air sucked from the air inlet 2 into the second fan case 7b.
[0019] Positions where the first fan case air inlet 10a and the second fan case air inlet 10b are provided are not limited to the front surface of the first fan case 7a and the front surface of the second fan case 7b. For example, the first fan case air inlet 7a and the second fan case air inlet 7b may be respectively provided on a rear surface of the first fan case air inlet 10a and a rear surface of the second fan case air inlet 10b.
Alternatively, each of the first fan case air inlet 10a and the second fan case air inlet 10b may be provided on both of the front surface and the rear surface of the corresponding fan case. Further alternatively, each of the first fan case air inlet 10a and the second fan case air inlet 10b may be provided on at least one of a left side surface and a right side surface of the corresponding fan case.
[0020] Fig. 2 is a diagram illustrating a state where the first fan case 7a and the second fan case 7b of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 are viewed from the right side surface side. As illustrated in Fig. 2, a first fan case air outlet lla and a second fan case air outlet 11b are respectively provided on a lower part on the right side surface of the first fan case 7a and a lower part on the right side surface of the second fan case 7b. In other words, the air passage for the air blown out from the first fan case 7a and the second fan case 7b are provided on a lower part of the housing 1. Further, the shapes of the first fan case air outlet lla and the second fan case air outlet llb are not limited.
[0021] Each of the first fan case 7a and the second fan case 7b is, for example, a bell-mouth having an elliptical shape. A first fan 9a is attached inside the first fan case 7a. The first fan 9a is connected to a first fan motor (not illustrated) rotating the first fan 9a. Likewise, a second fan 9b is attached inside the second fan case 7b. The second fan 9b is connected to a second fan motor (not illustrated) rotating the second fan 9b. Each of the first fan 9a and the second fan 9b is, for example, a sirocco fan. Further, each of the first fan motor and the second fan motor includes an inverter (not illustrated) converting direct-current power into alternative-current power.
[0022] The control box 6 is disposed on a downstream of the first fan case air inlet 10a and the second fan case air inlet 10b in a flow of the air. Further, the control box 6 is disposed in a portion other than an area that connects the first fan case air outlet lla to a first opening port 5a of the partition plate 5 in a longitudinal direction and a horizontal direction of the housing 1 and other than an area that connects the second fan case air outlet 11b to a second opening port 5b of the partition plate 5 in the longitudinal direction and the horizontal direction of the housing 1. In other words, the control box 6 is disposed in a portion other than the air passage for the air blown out from the first fan case air outlet lla and the second fan case air outlet 11b, on the downstream of the first fan case air inlet 10a of the first fan case 7a and the second fan case air inlet 10b of the second fan case 7b in the air passage.
[0023] Fig. 3 is a diagram explaining the arrangement configuration in a case where the first fan case 7a, the second fan case 7b, the control box 6, the partition plate 5, and the heat exchanger 4 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 are viewed from the front surface side. Fig. 4 is a diagram explaining the arrangement configuration in a case where the first fan case 7a, the second fan case 7b, the control box 6, the partition plate 5, and the heat exchanger 4 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 are viewed from an upper surface side.
[0024] As illustrated in Fig. 3 and Fig. 4, the first fan case air inlet 10a is provided on a front side surface of the first fan case 7a. The second fan case air inlet 10b is provided on a front side surface of the second fan case 7b. The partition plate 5 is disposed on the downstream in the air passage for the air blown out from the first fan case air outlet lla of the first fan case 7a and the second fan case air outlet llb of the second fan case 7b.
[0025] The partition plate 5 is a plate partitioning a space inside the housing 1 into a fan case space la where the first fan case 7a and the second fan case 7b are disposed, and a heat exchanger space lb where the heat exchanger 4 is disposed.
Fig. 7 is a diagram illustrating the partition plate 5 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 as viewed from the side surface of the housing 1 on the air outlet 3 side. As illustrated in Fig. 3 to Fig. 7, the partition plate 5 includes the first opening port 5a and the second opening port 5b at a lower part. The first opening port 5a is provided at a position corresponding to the air passage for the air blown out from the first fan case air outlet 11a. The first opening port 5a is formed to have a sufficient size not causing air passage pressure loss of the air blown out from the first fan case air outlet 11a. The second opening port 5b is provided at a position corresponding to the air passage for the air blown out from the second fan case air outlet 11b. The second opening port 5b is formed to have a sufficient size not causing air passage pressure loss of the air blown out from the second fan case air outlet 11b. The shapes of the first opening port 5a and the second opening port 5b are not limited. The partition plate 5 is attached inside the housing 1 not to allow the air in the fan case space la to flow into the heat exchanger space lb through a portion other than the first opening port 5a and the second opening port 5b.
[0026] The control box 6 has a cuboid shape, and includes a controller 6a inside thereof. The controller 6a controls, in addition to the first fan motor and the second fan motor of the indoor unit 100, a compressor, a four-way valve, an expansion valve, a fan, and other components of an unillustrated outdoor unit disposed outside the indoor unit 100. The controller 6a includes dedicated hardware, or a central processing unit (CPU, also referred to as central processing device, processing device, calculation device, microprocessor, microcomputer, or processor) executing programs stored in a memory. In a case where the controller 6a includes the dedicated hardware, the controller 6a corresponds to, for example, a single circuit, a composite circuit, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a combination thereof. Functional units realized by the controller 6a may be each realized by individual hardware, or may be realized by one hardware. In a case where the controller 6a includes the CPU, functions performed by the controller 6a are realized by software, firmware, or a combination of software and firmware. The software and the firmware are described as programs, and stored in the memory. The CPU realizes the functions of the controller 6a by reading out and executing the programs stored in the memory. For example, the memory is a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, and an EEPROM [0027] As illustrated in Fig. 4, the control box 6 is disposed near the partition plate 5 inside the housing 1. The control box 6 is disposed on the downstream of the first fan case air inlet 10a and the second fan case air inlet 10b in the flow of the air.
Further, the control box 6 is disposed in the portion other than the area that connects the first fan case air outlet lla to the first opening port 5a of the partition plate 5 in the longitudinal direction and the horizontal direction of the housing 1. Furthermore, the control box 6 is disposed in the portion other than the area that connects the second fan case air outlet 11b to the second opening port 5b of the partition plate 5 in the longitudinal direction and the horizontal direction of the housing 1. In other words, the control box 6 is disposed in the fan case space la in a portion other than the air passage between the first fan case air outlet lla and the first opening port 5a of the partition plate 5 and other than the air passage between the second fan case air outlet llb and the second opening port 5b of the partition plate 5. The fan case space la is a space inside the housing 1 that is defined by the partition plate 5 and in which the first fan case 7a and the second fan case 7b are disposed.
[0028] The position where the control box 6 is attached to the housing 1 is not limited to the position illustrated in Fig. 4. The control box 6 is attached to the housing 1 at a position in a portion other than the air passage between the air inlet 2 of the housing 1 and the first fan case air inlet 10a of the first fan case 7a and other than the air passage between the air inlet 2 of the housing 1 and the second fan case air inlet 10b of the second fan case 7b. Further, the control box 6 may be attached to the housing 1 at any position as long as the position is a position other than the air passage between the first fan case air outlet lla and the first opening port 5a of the partition plate 5 and other than the air passage between the second fan case air outlet 11b and the second opening port 5b of the partition plate 5 inside the fan case space la, and on the downstream of the first fan case air inlet 10a of the first fan case 7a and the second fan case air inlet 10b of the second fan case 7b in the air passage.
For example, the control box 6 may be disposed on the front surface side or the rear surface side in the fan case space 1a. Fig. 5 is a diagram explaining a case where the control box 6 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 is disposed on the front surface side. Fig. 6 is a diagram explaining a case where the control box 6 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1 is disposed on the front surface side of the second fan case 7b. More specifically, the control box 6 is disposed on the side surface side of the second fan case 7b (on a front side of the housing 1) and between the second fan case air inlet 10b and the second fan case air outlet 11b. At such a position of the control box 6, the air is flowed more gently as compared with the positions of the control box 6 illustrated in Fig. 4 and Fig. 5. This makes it possible to most efficiently reduce the air-passage resistance caused by the control box 6. Further, the control box 6 may be disposed on the upper surface side inside the housing 1 not to block the air passage between the air inlet 2 of the housing 1 and the first fan case air inlet 10a of the first fan case 7a, the air passage between the air inlet 2 of the housing 1 and the second fan case air inlet 10b of the second fan case 7b, the air passage between the first fan case air outlet lla and the first opening port 5a of the partition plate 5, and the air passage between the second fan case air outlet llb and the second opening port 5b of the partition plate 5. Note that a method of attaching the control box 6 to the housing 1 is not limited.
[0029] The heat exchanger 4 causes heat exchange to be performed between the air having passed through the first opening port 5a and the second opening port 5b of the partition plate 5 and refrigerant flowing through a pipe (not illustrated) of the heat exchanger 4. The heat exchanger 4 is disposed obliquely to a front-rear direction inside the housing 1. The air having passed through the heat exchanger 4 is blown out from the air outlet 3 provided on the right side surface of the housing 1.
[0030] In the indoor unit 100 for the air-conditioning apparatus according to Embodiment 1, the control box 6 is disposed in the portion other than the air passage between the air inlet 2 of the housing 1 and the first fan case air inlet 10a of the first fan case 7a and other than the air passage between the air inlet 2 of the housing 1 and the second fan case air inlet 10b of the second fan case 7b. Further, the control box 6 is disposed at the position other than the air passage between the first fan case air outlet lla and the first opening port 5a of the partition plate 5 and other than the air passage between the second fan case air outlet 11b and the second opening port 5b of the partition plate 5, and on the downstream of the first fan case air inlet 10a of the first fan case 7a and the second fan case air inlet 10b of the second fan case 7b in the air passage.
[0031] At the position where the control box 6 is disposed, the flow of the air is gentle as compared with the upstream side of the first fan case air inlet 10a of the first fan case 7a and the second fan case air inlet 10b of the second fan case 7b. Therefore, it is possible to reduce the air-passage resistance caused by the control box 6 in the housing 1 of the indoor unit 100, which makes it possible to reduce the amount of air sent by the fan.
[0032] Embodiment 2 The indoor unit 100 for the air-conditioning apparatus according to Embodiment 2 is obtained by changing the form of the heat exchanger 4. Fig. 8 is a diagram explaining an arrangement configuration in a case where the first fan case 7a, the second fan case 7b, the control box 6, the partition plate 5, and the heat exchanger 4 of the indoor unit 100 for the air-conditioning apparatus according to Embodiment 2 are viewed from the front surface side.
