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. Here, although not particularly limited, the compressor 210 may be capable of changing the capacity of the compressor 210 by arbitrarily changing the operating frequency by, for example, an inverter circuit or the like. The capacity of the compressor 210 represents the amount of refrigerant delivered per unit time. The four-way valve 220 is a valve that switches the flow of the refrigerant depending on, for example, the cooling operation and the heating operation.

The outdoor heat exchanger 230 exchanges heat between the refrigerant and the outdoor air. The outdoor heat exchanger 230 functions as an evaporator during the heating operation to evaporate and vaporize the refrigerant. Further, the outdoor heat exchanger 230 functions as a condenser during the cooling operation to condense and liquefy the refrigerant.

The expansion valve 240 is, for example, a throttle device or the like, and decompresses the refrigerant to expand it. For example, when the expansion valve 240 is configured by an electronic expansion valve or the like, the opening degree of the expansion valve 240 is adjusted based on an instruction of a control device or the like (not shown). The indoor heat exchanger 110 exchanges heat between the air in the air-conditioned space and the refrigerant. The indoor heat exchanger 110 functions as a condenser during the heating operation to condense and liquefy the refrigerant. Further, the indoor heat exchanger 110 functions as an evaporator during the cooling operation, and evaporates and vaporizes the refrigerant.

That is, the refrigeration cycle circuit of the air conditioner 500 includes a compressor 210, a four-way valve 220, an outdoor heat exchanger 230, an expansion valve 240, and an indoor heat exchanger 110.

FIG. 2 is a perspective view of the indoor unit of the air conditioner according to the embodiment of the present invention as viewed from below. FIG. 3 is a vertical cross-sectional view of the indoor unit of the air conditioner according to the embodiment of the present invention. Further, FIG. 4 is a perspective view of the inside of the indoor unit of the air conditioner according to the embodiment of the present invention as viewed from below the indoor unit. In other words, FIG. 4 is a view of the indoor unit 100 with the decorative panel 2 removed from below. The black arrow at the tip shown in FIG. 3 indicates the air flow in the indoor unit 100.

The indoor unit 100 according to the present embodiment is a four-way blowing type indoor unit that blows air in four directions, and is embedded in the ceiling of an air-conditioned space such as a room or suspended from the ceiling of the air-conditioned space. Is installed. The indoor unit 100 includes a main body 1 and a decorative panel 2 as parts constituting the outer shell of the indoor unit 100. The main body 1 is a box body having a substantially rectangular parallelepiped shape. The main body 1 has an opening formed on a surface that becomes a lower surface when installed on the ceiling. The decorative panel 2 is attached to the main body 1 so as to cover the opening of the main body 1. A suction port 2a is formed in the decorative panel 2 at a substantially central portion. Further, the decorative panel 2 is formed with four outlets 2b so as to surround the suction port 2a.

Further, inside the main body 1, a fan 3 which is a centrifugal fan such as a turbo fan is provided at a position facing the suction port 2a. The fan 3 sucks the air in the air-conditioned space from the suction port 2a into the main body 1 and blows it out to the indoor heat exchanger 110. Further, inside the main body 1, an indoor heat exchanger 110 is provided so as to surround the fan 3. The indoor heat exchanger 110 exchanges heat between the refrigerant flowing inside the indoor heat exchanger 110 and the air in the air-conditioned space sucked into the main body 1 by the fan 3.

The indoor heat exchanger 110 is arranged at a position on the outer peripheral side of the suction port 2a and on the inner peripheral side of the air outlet 2b in a plan view. Therefore, as shown by the black-painted arrow at the tip in FIG. 3, the air in the air-conditioned space is sucked into the main body 1 from the suction port 2a by the rotation of the fan 3 and flows into the indoor heat exchanger 110. It is configured to do. Further, the air in the air-conditioned space flowing into the indoor heat exchanger 110 exchanges heat with the refrigerant flowing inside the indoor heat exchanger 110 when passing through the indoor heat exchanger 110, and enters the air-conditioned space from the outlet 2b. It is configured to be blown out. When the indoor heat exchanger 110 functions as an evaporator, the dew point temperature may be reached when the air in the air-conditioned space is cooled by the indoor heat exchanger 110, and dew condensation may occur in the indoor heat exchanger 110. .. Then, the dew adhering to the indoor heat exchanger 110 may fall from the indoor heat exchanger 110. Therefore, below the indoor heat exchanger 110, a dew receiving component 30 that receives the dew that has fallen from the indoor heat exchanger 110 is provided.

Further, in order to prevent the air blown from the fan 3 from being blown out from the outlet 2b without passing through the indoor heat exchanger 110, the inside of the main body 1 is formed at both ends of the indoor heat exchanger 110. A shielding plate 10 is provided between them to close the gap between both ends of the indoor heat exchanger 110.

FIG. 5 is a perspective view of the periphery of the shielding plate of the indoor unit according to the embodiment of the present invention as viewed from the fan side, and is a view of the periphery of the shielding plate as viewed from below. Further, FIG. 6 is a perspective view of the periphery of the shielding plate of the indoor unit according to the embodiment of the present invention as viewed from the side opposite to the fan, and is a view of the periphery of the shielding plate as viewed from below.
The indoor heat exchanger 110 includes a refrigerant pipe 111 through which a refrigerant flows. Further, in the present embodiment, the indoor heat exchanger 110 is a fin tube type heat exchanger. Therefore, a plurality of heat transfer fins 112 are connected to the refrigerant pipe 111. Each of the heat transfer fins 112 is arranged at a predetermined interval.

The refrigerant pipe 111 of the indoor heat exchanger 110 is provided with, for example, a temperature sensor 20 which is a thermistor. One end of the wiring 21 is connected to the temperature sensor 20. The other end of the wiring 21 is connected to a control device (not shown). Then, the control device (not shown) uses the temperature of the refrigerant pipe 111 detected by the temperature sensor 20 as the temperature of the refrigerant flowing through the refrigerant pipe 111, and controls the refrigeration cycle circuit of the air conditioner 500.

Further, the temperature sensor 20 is provided on the side opposite to the fan 3 with the shielding plate 10 as a reference. In other words, the shielding plate 10 is provided between the temperature sensor 20 and the fan 3. Therefore, the shielding plate 10 blocks the flow of air blown from the fan 3 toward the temperature sensor 20. As a result, it is possible to prevent the air blown out from the fan 3 from directly hitting the temperature sensor 20, and it is possible to prevent the temperature sensor 20 from erroneously detecting the temperature of the refrigerant pipe 111.

The above-mentioned wiring 21 having one end connected to the temperature sensor 20 is routed in the main body 1 and connected to a control device (not shown). Further, the wiring 21 is routed so as to straddle the shielding plate 10.

In other words, the portion of the wiring 21 arranged on the side opposite to the fan 3 with respect to the shielding plate 10 is routed as shown in FIGS. 5 and 6. Specifically, when observing the wiring 21 from the end connected to the temperature sensor 20 toward the end connected to the control device, the wiring 21 is arranged on the opposite side of the fan 3 with the shielding plate 10 as a reference. The portion of the wiring 21 that is provided has a portion that extends downward and then extends upward. The portion extending downward and then extending upward is arranged above the dew receiving component 30 shown in FIG.

As described above, when the indoor heat exchanger 110 functions as an evaporator, the dew point temperature is reached when the air in the air-conditioned space is cooled by the indoor heat exchanger 110, and dew condensation occurs in the indoor heat exchanger 110. In some cases. Since the temperature sensor 20 is also cooled by the refrigerant flowing through the refrigerant pipe 111 of the indoor heat exchanger 110, dew condensation may occur on the temperature sensor 20 as well. At this time, there is a concern that the dew adhering to the temperature sensor 20 will move along the wiring 21 and fall into the air-conditioned space. However, in the present embodiment, the portion of the wiring 21 arranged on the side opposite to the fan 3 with respect to the shielding plate 10 has a portion extending downward and then extending upward. The portion extending downward and then extending upward is arranged above the dew receiving component 30. Therefore, when the dew adhering to the temperature sensor 20 moves along the wiring 21, the dew falls on the dew receiving component 30 from the portion where the dew extends downward and then extends upward. Therefore, the indoor unit 100 according to the present embodiment can prevent the dew adhering to the temperature sensor 20 from falling into the air-conditioned space.

Further, the intermediate portion of the wiring 21 is fixed to the shielding plate 10 after straddling the shielding plate 10.

In the present embodiment, the upper side edge portion of the shielding plate 10 is the first side edge portion 11a. The second side edge portion 11b is a side edge portion on the opposite side of the first side edge portion 11a. That is, in the present embodiment, the lower side edge portion of the shielding plate 10 is the second side edge portion 11b.

The third side edge portion 11c and the fourth side edge portion 11d are side edge portions that connect the end portion of the first side edge portion 11a and the end portion of the second side edge portion 11b. That is, in the present embodiment, one of the left side edge portion or the right side edge portion becomes the third side edge portion 11c, and the other of the left side side edge portion or the right side edge portion becomes the fourth side edge portion 11d. It becomes. As described above, the shielding plate 10 according to the present embodiment closes the gap between both ends of the indoor heat exchanger 110. Therefore, the third side edge portion 11c and the fourth side edge portion 11d of the shielding plate 10 are fixed to both ends of the indoor heat exchanger 110, for example, by screwing.

Here, in the shielding plate 10 according to the present embodiment, the first side edge portion 11a is formed with a V-shaped notch 12 that is recessed toward the second side edge portion 11b. Further, in the present embodiment, the first side edge portion 11a is subjected to a close contact bending process at least in a range where the notch 12 is formed. That is, the edge of the notch 12 is subjected to a close contact bending process. The close contact bending process is a process of bending the end portion by about 180 ° and folding it back. In the present embodiment, even if a part of the V-shaped valley portion or the like has a curved shape, it is V-shaped as long as it approaches the second side edge portion 11b side toward the valley portion. It will be called a shape.

Further, in the shielding plate 10 according to the present embodiment, the main body portion 11 includes a clamp 13 for fixing the wiring 21 between the notch 12 of the first side edge portion 11a and the second side edge portion 11b. ing. The number of clamps 13 is not particularly limited, but the main body 11 according to the present embodiment includes two clamps 13. The clamp 13 includes a mounting portion 13a and a fixing portion 13b. The mounting portion 13a is a portion to be mounted on the main body portion 11. In the present embodiment, the attachment portion 13a of the clamp 13 is attached to the main body portion 11 by spot welding or the like. The fixing portion 13b is a portion for fixing the wiring 21. The fixing portion 13b is made of a flexible material. The wiring 21 is fixed to the clamp 13 by bending the fixing portion 13b and sandwiching the wiring 21. Note that FIGS. 5 and 6 show a state before the fixing portion 13b is bent. Further, the configuration of the fixing portion 13b is merely an example. The configuration of the fixing portion 13b is not limited to the configuration as long as the wiring 21 can be fixed.

Further, in the present embodiment, the fixing portion 13b is arranged in the width of the notch 12 in the direction in which the first side edge portion 11a extends. More specifically with reference to FIG. 5, the first side edge portion 11a extends in the left-right direction. The left end portion of the fixing portion 13b is arranged on the right side of the left end portion of the notch 12. Further, the right end portion of the fixing portion 13b is arranged on the left side of the right end portion of the notch 12.

The shielding plate 10 configured as described above is attached to the main body 1 by, for example, screwing. That is, in the present embodiment, the main body 1 is a member to be attached to which the shielding plate 10 is attached. Specifically, the shielding plate 10 includes a foot portion 14 protruding from the first side edge portion 11a. In this embodiment, the shielding plate 10 includes two foot portions 14. The foot portion 14 projects from a range in which the notch 12 of the first side edge portion 11a is not formed. Then, the foot portion 14 is attached to the main body portion 1 by, for example, screwing, so that the shielding plate 10 is attached to the main body portion 1. The gap 15 formed between the first side edge portion 11a and the foot portion 14 is preferably smaller than the diameter of the wiring 21. As will be described later, the wiring work of the wiring 21 becomes easier.
