[0029] When the digital indoor unit needs to be installed, the staff first passes the screws through the fixing holes 23 and fixes the installation chamber 1 on the wall to be installed. Then the staff aligns the protrusions 5 and the guide grooves 4 at the upper and lower ends of the digital indoor unit back panel 2, and pushes the digital indoor unit back panel 2 into the interior of the installation chamber 1. When the digital indoor unit back panel 2 is pushed in, the left and right sides of the installation chamber 1 will abut against the inclined surfaces of the installation heads 8, and the installation heads 8 are pushed into the interior of the slots 7. At this time, the spring 9 is compressed. When the digital indoor unit back panel 2 completely enters the interior of the installation chamber 1, the installation holes 6 at the left and right ends of the digital indoor unit back panel 2 will be aligned with the positions of the installation heads 8. At this time, the installation is lost. The mounting head 8 abutting against the outer wall of the mounting bin 1 will enter the interior of the mounting hole 6 through the elastic potential energy of the spring 1 9, so that the digital indoor unit back panel 2 is fixed. When it needs to be removed, the staff presses the button 15, and the button 15 pushes the control rod 12 in, so that the tooth 2 13 drives the gear 11 to rotate. At this time, the spring 2 14 is squeezed, and the rotation of the gear 11 will drive the mounting head 8 to move through the tooth 10, so that the mounting head 8 is stored in the interior of the slot 7. At this time, the digital indoor unit back panel 2 that has lost the fixing of the mounting head 8 can be removed, and the heat sink 16 will use the elastic potential energy of the spring 3 17 to push the digital indoor unit back panel 2 slightly outward to facilitate the staff to take it.

[0030] By setting the mounting head 8, when the digital indoor unit back panel 2 is pushed into the mounting chamber 1, the mounting head 8 will be first received into the inside of the slot 7, and after the digital indoor unit back panel 2 completely enters the inside of the mounting chamber 1, the mounting head 8 enters into the inside of the mounting hole 6 through the elastic potential energy of the spring 9, so that the digital indoor unit back panel 2 is installed. The mounting hole 6 can also be unfixed by pressing the button 15 and ejected by the heat sink 16. Compared with the traditional device, the device fixes the digital indoor unit back panel 2 inside the mounting chamber 1, so that the staff does not need to dismantle the entire device when it is necessary to repair or replace the digital indoor unit back panel 2, thereby ensuring the beauty of the wall, and the digital indoor unit back panel 2 is quick to dismantle and easy to install, thereby improving user satisfaction.

[0031] Among them, heat dissipation holes 18 are opened at the upper and lower ends of the installation chamber 1;

[0032] A heat sink 19 is provided at the bottom of the installation bin 1, and bolts 20 are rotatably installed at the four corners of the heat sink 19. The top of the bolt 20 penetrates into the interior of the installation bin 1 and is threadedly sleeved with the installation bin 1. A motor 21 is fixedly installed at the bottom of the installation bin 1, and fan blades 22 are rotatably installed inside the heat sink 19. The output shaft of the motor 21 and the fan blades 22 are fixedly connected.

[0033] When the digital indoor unit back panel 2 and the operation panel 3 are fixed and used normally, the staff can fix the heat sink 19 to the bottom of the installation chamber 1 through the bolts 20, and then start the motor 21. The operation of the motor 21 drives the fan blades 22 to rotate, and the fan blades 22 will discharge the hot air inside the installation chamber 1 through the heat dissipation holes 18 to provide heat dissipation for the digital indoor unit back panel 2 running inside the installation chamber 1. At this time, the heat sink 16 and the digital indoor unit back panel 2 are abutted against each other, and because the copper material of the heat sink 16 and the heat dissipation silicone grease have good thermal conductivity, the heat sink 16 absorbs the heat generated by the digital indoor unit back panel 2, and a gap is left between the heat sink 16 and the installation chamber 1, so that the hot air is discharged from the gap by the heat sink 19.

[0034] Through the elastic potential energy of the spring three 17, the heat sink 16 and the digital indoor unit back panel 2 are in contact with each other, and because the copper material of the heat sink 16 and the heat dissipation silicone grease have good thermal conductivity, the heat sink 16 absorbs the heat generated by the digital indoor unit back panel 2, and through the operation of the motor 21, the fan blades 22 discharge the hot air in the installation compartment 1. Compared with the traditional device, the device provides a guarantee for the long-term operation of the digital indoor unit back panel 2 through the setting of the heat sink 19, and through the setting of the heat sink 16, the heat dissipation efficiency of the digital indoor unit back panel 2 is better, thereby increasing the service life of the device.

[0035] Among them, guiding grooves 4 are provided at both the upper and lower ends of the installation bin 1, and bumps 5 are fixedly installed at both the upper and lower ends of the digital indoor unit back panel 2. The bumps 5 are clamped inside the guiding grooves 4.

[0036] Through the arrangement of the guiding grooves 4 and the bumps 5, the digital indoor unit back panel 2 is installed to prevent the offset of the digital indoor unit back panel 2.

[0037] Among them, the shape of the installation head 8 is a right trapezoid, and the inclined surface of the installation head 8 faces the front side. The installation head 8 is located inside the installation hole 6.

[0038] When the digital indoor unit back panel 2 is pushed in, the left and right sides of the installation bin 1 will abut against the inclined surface of the installation head 8 and push the installation head 8 into the inside of the notch 7. When the digital indoor unit back panel 2 completely enters the inside of the installation bin 1, the installation holes 6 at both the left and right ends of the digital indoor unit back panel 2 will be aligned with the position of the installation head 8, enabling it to enter the inside of the installation hole 6.

[0039] Among them, a heat dissipation plate 16 is movably installed inside the installation bin 1, and the back of the heat dissipation plate 16 is elastically connected to the inner wall of the installation bin 1 through a third spring 17.

[0040] When the fixation of the digital indoor unit back panel 2 is lost, the heat dissipation plate 16 will slightly push out the digital indoor unit back panel 2 through the elastic potential energy of the third spring 17, facilitating the staff to take it.

[0041] Among them, the front side of the heat dissipation plate 16 abuts against the back of the digital indoor unit back panel 2. The heat dissipation plate 16 is made of copper, and a heat-conducting silicone grease is applied to its front side.

[0042] When the digital indoor unit back panel 2 is fixed, the heat dissipation plate 16 will absorb the heat generated by the digital indoor unit back panel 2.

[0043] Among them, fixing ports 23 are fixedly installed at the four corners of the installation bin 1, and the fixing ports 23 can be fixed to the wall through screws.

[0044] The staff fixes the fixing ports 23 to the wall through screws to complete the installation of the installation bin 1.

[0045] The working principle and usage process of the present utility model:

[0046] When the digital indoor unit needs to be installed, the staff first passes the screw through the fixing port 23 and fixes the installation bin 1 on the wall to be installed. Then, the staff aligns the bumps 5 at the upper and lower ends of the digital indoor unit back plate 2 with the guiding grooves 4, and pushes the digital indoor unit back plate 2 into the interior of the installation bin 1. When the digital indoor unit back plate 2 is pushed in, the left and right sides of the installation bin 1 will abut against the inclined surfaces of the installation heads 8 and push the installation heads 8 into the interior of the notch 7. At this time, the first spring 9 is compressed. When the digital indoor unit back plate 2 completely enters the interior of the installation bin 1, the installation holes 6 at the left and right ends of the digital indoor unit back plate 2 will be aligned with the positions of the installation heads 8. At this time, the installation heads 8 that lose the abutment against the outer wall of the installation bin 1 will enter the interior of the installation holes 6 through the elastic potential energy of the first spring 9, completing the fixation of the digital indoor unit back plate 2. When it needs to be removed, the staff presses the button 15, and the button 15 pushes the control rod 12 in, causing the second tooth 13 to drive the gear 11 to rotate. At this time, the second spring 14 is squeezed, and the rotation of the gear 11 will drive the installation head 8 to displace through the first tooth 10, making the installation head 8 retracted into the interior of the notch 7. At this time, the digital indoor unit back plate 2 that loses the fixation of the installation head 8 can be disassembled, and the heat dissipation plate 16 will slightly push the digital indoor unit back plate 2 outwards through the elastic potential energy of the third spring 17, facilitating the staff to take it.

[0047] When the fixation between the digital indoor unit back plate 2 and the operation panel 3 is completed and it is in normal use, the staff can fix the heat dissipation row 19 at the bottom of the installation bin 1 through the bolt 20, and then start the motor 21. The operation of the motor 21 drives the fan blade 22 to rotate, and the fan blade 22 will discharge the hot air inside the installation bin 1 through the heat dissipation holes 18, providing heat dissipation for the digital indoor unit back plate 2 operating inside the installation bin 1. At this time, the heat dissipation plate 16 and the digital indoor unit back plate 2 are in mutual contact, and due to the good thermal conductivity of the copper material of the heat dissipation plate 16 and the thermal grease, the heat dissipation plate 16 absorbs the heat generated by the digital indoor unit back plate 2, and there is a gap between the heat dissipation plate 16 and the installation bin 1, enabling the hot air to be discharged by the heat dissipation row 19 from the gap.
