The outer periphery-side waterproof rib 601 is provided on the lid 106 at the edge of the lid 106 not connected to the outer periphery 503. In a state where the lid 106 is covered on the junction box 105, the outer waterproof rib 601 is positioned on the outer periphery side of the inner waterproof rib 540.
The lead through opening 602 is an opening that penetrates the cover 106 and allows the lead 108 to enter the junction box 105 from the outside of the cover 106. In a state where the cover 106 covers the junction box 105, the lead insertion opening 602 is positioned below the operation opening 510. In other words, the upper end of the lead insertion opening 602 is located below the lower end of the operation port 510, and therefore the lead 108 can pass through the lead insertion opening 602 and the operation port 510 only from the lower portion to the upper portion.
When the cover 106 covers the junction box 105, the cover 106 covers the operation opening 510.
The lead wire housing 603 projects outward of the frame 101 on a cover plane constituting the cover 106, and houses the lead wire 108. In a state where the lid 106 is covered on the junction box 105, the lead 108 is fixed to the lead housing 603.

The lead wire housing opening 620 communicates with the lead wire insertion opening 602 and is an opening toward the lower portion of the frame 101. In a state where the cover 106 is covered on the junction box 105, the lead 108 penetrates the lead housing opening 620.
The above description is a description of the structure of the air-conditioning apparatus 100 according to the embodiment of the present invention.
Next, the assembly of the terminal box 105 and the lid 106 of the air conditioning apparatus and the operation thereof will be described with reference to fig. 1 to 6.
When a user wants to control the air-conditioning apparatus 100 by the external line controller 107, the external line controller 107 needs to be connected to the air-conditioning apparatus 100. In other words, the lead 108 with a connection terminal, which is required to be connected to the external line controller 107, is inserted into the connection terminal 501 provided in the air-conditioning apparatus 100. As shown in fig. 1, the air conditioner of the present invention has a terminal box 105. When the lid 106 is opened, the terminal 501 provided in the terminal block 105 is exposed. Then, the lead wire 108 is inserted through the lead wire insertion opening 602 and then inserted through the operation port 510, and then, the terminal 501 provided in the air-conditioning apparatus 100 can be connected from the outside. In other words, the lead 108 can be simply connected to the connection terminal 501 without opening the circuit board box 104. Thereby avoiding a user from making strong electrical contact with the inside of the circuit board case 104 and improving the convenience of mounting the lead 108 and the safety of the air conditioning device 100. In addition, the upper end of the lead through opening 602 is disposed below the lower end of the operation port 510, in other words, the lead through opening 602 is disposed below the operation port 510. Therefore, the lead wire 108 is connected to the terminal 501 only from below to above, and in other words, even if water or water vapor falls on the lead wire 108, the water or water vapor flows down along the lead wire 108 by its own weight. Thereby preventing water or water vapor from coming into contact with the terminal block 501 along the lead wires, further improving the safety of the air-conditioning apparatus 100.
As shown in fig. 4, when the lid 106 is closed after the lead 108 is connected to the terminal 501, the lead 108 passing through the lead insertion opening 602 enters the lead storage 603 from the lead storage opening 620 communicating with the lead insertion opening 602, and when the lid 106 covers the terminal block 105, the lead 108 is stored in the lead storage 603. Thereby shortening the gap between the terminal block 105 and the lid portion 106 and further avoiding the contact of water or water vapor with the terminal 501 along the lead 108. The lead 108 entering the lead housing 603 is guided to the operation opening 510 by the lead guide portion 610, and the lead 108 is securely connected to the terminal 501 from below to above.
When the lid 106 is placed on the terminal box 105, as shown in fig. 4, the sealing rib 550 is provided around the operation port 510, so that water or water vapor is prevented from entering the terminal housing 502 through the operation port 510. Further, a part of the seal rib 550 is located between the operation port 510 and the lead through opening 602, and the lead 108 comes into contact with the seal rib 550 when the lid portion 106 is closed. Therefore, the gap between the lead 108 and the lead housing 603 is reduced by reducing the distance between the lead 108 and the lead housing 603, so that the contact of water or water vapor with the terminal 501 along the lead 108 is avoided, and the safety of the air-conditioning apparatus 100 is improved.
Further, since the bottom surface 530 of the terminal box 105 is inclined from the upper portion toward the lower portion in the direction of the operation port 510 from the surface facing the operation port 510, water or steam is discharged toward the operation port 510 side along the bottom surface 530 even if water enters the terminal box 105. Thereby further improving the safety of the air conditioning device 100.
In order to prevent water or water vapor from entering the frame 101 through the frame opening 130, as shown in fig. 6, an inner circumferential waterproof rib 540 surrounding the frame opening 130 is provided on an inner surface of the outer circumferential portion 503 facing the outer circumferential surface of the frame 101, and an outer circumferential waterproof rib 601 is provided on an outer circumferential side covering the inner circumferential waterproof rib 540, thereby achieving double protection against water or water vapor intrusion. It is thus confirmed that water or water vapor does not enter the frame 101 from the frame opening 130, and the safety of the air conditioning device 100 is greatly improved.
In addition, as shown in fig. 2, the junction box 105 is separated from the circuit board box 104, so that even if water or water vapor enters the junction box 105, the water or water vapor cannot directly enter the circuit board box 104, thereby protecting the circuit board box 104.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
