However, since the air conditioner of Patent Document 1 requires a connector as a separate member for connecting both the internal wiring and the external wiring, the cost increases and the internal wiring and the external wiring are connected. It takes a lot of work man-hours. In addition, since the connector is detachably attached to the locking part on the back of the main body, cold air may be guided from the internal space of the indoor unit to the external space through the gap of the locking part, causing problems such as dew condensation. There is sex.

The present invention has been made in view of such circumstances, and does not require a separate member for connecting wiring between the internal space accommodating the internal equipment and the external space, and the internal space and the external space are not required. It is an object of the present invention to provide an air conditioner capable of passing wiring between spaces and preventing leakage of air conditioning air from an internal space to an external space.

In order to solve the above problems, the air conditioner of the present invention employs the following means.
The air exchanger according to one aspect of the present invention is arranged so as to surround a fan that causes air flowing in from a suction port along the axial direction of the rotating shaft to flow out in a radial direction intersecting the axial direction, and an outer periphery of the fan. It has a heat exchanger, a cabinet portion that accommodates the fan and internal equipment including the heat exchanger in an internal space, and has a substantially rectangular cross section orthogonal to the axial direction, and has the suction port. Around the rotation axis, the panel portion having a substantially rectangular cross section orthogonal to the axial direction is in contact with the first end surface of the cabinet portion in the axial direction and the second end surface of the panel portion in the axial direction. The seal portion comprises a seal portion forming a substantially rectangular seal region extending to the inside, and the seal portion has a wiring lead-out portion for drawing out the wiring of the internal device from the internal space to the external space, and the wiring lead-out portion includes a wiring lead-out portion. A first recess provided on one of the first end face and the second end face and retracted in the axial direction, and a height in the axial direction above the first recess in a non-deformed state while being arranged in the first recess. It is arranged in the first recess in a state where the first seal member having an elastic deformability and the first seal member are sandwiched between them, and in the non-deformable state, the height in the axial direction is higher than that of the first seal member. A pair of second seal members that are highly elastically deformable, and the seal portion forms the seal region in a state where the wiring is arranged on the first seal member.

According to the air conditioner according to one aspect of the present invention, the seal portion that contacts the first end surface of the cabinet portion that accommodates the internal equipment in the internal space and the second end surface of the panel portion that has the suction port is provided around the rotation axis. A sealing area on an extending substantially rectangular shape is formed, and leakage of air conditioning air from the internal space to the external space is prevented. The wiring lead-out portion of the seal portion includes a first seal member arranged in the first recess and a pair of second seal members arranged in a state where the first seal member is sandwiched between the first recesses. When the seal portion forms the seal region with the wiring arranged on the first seal member, the first seal member is crushed by the wiring and both side surfaces are attracted to the wiring side. Although a gap is formed by attracting both side surfaces of the first seal member to the wiring side, the second seal member invades the gap and fills the gap. This is because, in the non-deformed state, the first seal member has a height in the axial direction equal to or higher than the first recess, and the second seal member is higher than the height in the axial direction of the first seal member. That is, it prevents a part of the second seal member having a large volume in the non-deformed state from invading the first seal member side attracted to the wiring side and forming a gap.

As shown in FIG. 11, when the fifth seal member 48 comes into contact with the second seal member 44 and is elastically deformed, the height in the axis X direction is compressed from the height H2 shown in FIG. 10 to the height H1. Further, a part of the fifth seal member 48 invades the gap vacated by the fourth seal member 47 being attracted to the wiring C side. As a result, the length of the contact surface of the fifth seal member 48 with the second seal member 44 is expanded from W2 to W2a, and the length of the contact surface with the recess 46 is maintained at W2.

According to the air conditioner 1 of the present embodiment, the wiring lead-out portion 41 of the seal portion 40 is arranged in a state where the fourth seal member 47 arranged in the recess 46 and the fourth seal member 47 are sandwiched between the recess 46. It is provided with a pair of fifth seal members 48 to be formed. When the seal portion 40 forms the seal region SA with the wiring C arranged on the fourth seal member 47, the fourth seal member 47 is crushed by the wiring C and both side surfaces are attracted to the wiring C side. Although the gap CL is formed by attracting both side surfaces of the fourth seal member 47 to the wiring C side, the fifth seal member 48 invades the gap CL and fills the gap CL. This is because the fourth seal member 47 has a height in the axis X direction above the recess 46 and the fifth seal member 48 is higher than the height in the axis X direction of the fourth seal member 47 in the non-deformed state. be. That is, it prevents a part of the fifth seal member 48 having a large volume in the non-deformed state from invading the fourth seal member 47 side attracted to the wiring C side and forming a gap CL.

[Other embodiments]
In the above description, the wiring C arranged on the first seal member 43 is assumed to be a single wiring, but other embodiments may be used. For example, a plurality of wirings C assembled by a binding tool (not shown) may be arranged on the first seal member 43.
