In addition, the indoor air-conditioning position structure has good noise-proof and heat-insulating performance. The indoor air-conditioning position structure with energy-saving and noise-proof performance of the present invention is described below with reference to the accompanying drawings.

[0038] See Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the indoor air conditioning structure with energy-saving and noise-proof performance of the present invention in the open and closed states. Figure 1 , the indoor air-conditioning structure with energy-saving and noise-proof performance of the present invention is described.

[0039] like Figure 1 As shown, the indoor air conditioning structure with energy-saving and noise-proof performance of the present invention includes:

[0040] A recessed space 11 is formed on the building's exterior facade and is recessed inwardly for accommodating an air conditioner outdoor unit 21. The top of the recessed space 11 is connected to the interior of the building through an opening;

[0041] a cover plate 17 that blocks the opening and can be opened and closed; and

[0042] An access door 14 is opened and closed to block the opening and is located above the cover plate 17. A heat insulation board 15 and a sound insulation board 16 are filled between the access door 14 and the cover plate 17, and the interior of the access door 14 is filled with sound insulation and heat preservation materials.

[0043] Specifically, the recessed space 11 is arranged along each floor, and one side of the recessed space 11 is a building partition wall, that is, the side wall of the recessed space 11 is a full-length wall, and the other two sides of the recessed space 11 are side walls formed by the inward recess of the building facade that match the shape of the air-conditioning outdoor unit. The recessed space 11 is provided with a shielding plate on the outside of the building facade to block the air-conditioning outdoor unit 21. The recessed space 11 can be arranged under the window of each floor.

[0044] Preferably, the cover plate 17 is made of a sound-insulating aluminum plate.

[0045] Preferably, the sound insulation and heat preservation material filled inside the inspection door 14 is an aluminum honeycomb panel.

[0046] As a preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, it also includes a supporting member 12 arranged along the inner side wall of the recessed space 11. The supporting member 12 is arranged close to the opening and a hook portion 121 bent upward is formed at the bottom of the supporting member 12.

[0047] The cover 17 is provided with a folded edge portion along the periphery thereof corresponding to the hook portion 121. The folded edge portion is correspondingly engaged with the hook portion 121, so that the cover 17 is mounted on the supporting member 12, thereby blocking the opening of the recessed space 11. When the cover 17 needs to be opened, the cover 17 is lifted upward so that the folded edge portion is disengaged from the hook portion 121 and the cover 17 can be taken out.

[0048] Preferably, a first rubber strip is provided between the hook portion 121 and the corresponding folded edge portion to further seal the gap between the supporting member 12 and the cover plate 17 to achieve the effects of heat preservation and noise reduction.

[0049] As another preferred embodiment of the present invention, Figure 4 、 Figure 5 and Figure 6 As shown, it also includes a fixing frame 13 arranged along the top of the side wall of the recessed space 11, and a first clamping member is provided on the fixing frame 13;

[0050] One side of the inspection door 14 is hinged to the side corresponding to the fixed frame 13, and the other side of the inspection door 14 is provided with a second clip corresponding to the first clip. Through the cooperation connection of the second clip and the first clip, the inspection door 14 is fixedly buckled on the fixed frame 13 and blocks the opening of the recessed space 11.

[0051] Preferably, the fixing frame 13 is installed on three side edges of the opening of the recessed space 11, and the inspection door 14 is hinged on the side wall of the recessed space 11 on the side where the fixing frame 13 is not installed, so as to facilitate the installation of the fixing frame 13 and the inspection door 14.

[0052] Furthermore, the first clamping member includes a protrusion 131 provided on the inner edge of the fixing frame 13 and a first barb 132 provided on the outer edge of the fixing frame 13;

[0053] The second clamping member includes a groove 141 opened on the inspection door 14 and corresponding to the protrusion 131, and a second hook 142 provided on the inspection door 14 and corresponding to the first hook 132. The protrusion 131 is engaged with the groove 141 and the first hook 132 is hooked with the second hook 142 so that the inspection door 14 is fixedly fastened to the fixed frame 13, that is, when the inspection door 14 is rotated in a direction close to the air-conditioning outdoor unit 21, the groove 141 on the inspection door 14 is engaged with the protrusion 131 and the second hook 142 is hooked with the first hook 132. At this time, the inspection door 14 is fixedly connected to the fixed frame 13. When the inspection door 14 is rotated in a direction away from the air-conditioning outdoor unit 21, the second hook 142 is disengaged from the first hook 132 and the groove 141 on the inspection door 14 is also disengaged from the protrusion 131, so that the inspection door 14 can be opened.

[0054] Specifically, the width of the top surface of the protrusion 131 is smaller than the width of the bottom surface of the protrusion 131, and the end of the protrusion 131 forms a slope. The groove 141 matches the protrusion 131, and the side of the groove 141 close to the bottom surface of the protrusion 131 is provided with a chamfer that matches the slope of the protrusion 131. By rotating the door leaf downward, the protrusion 131 can be more smoothly inserted into the groove 141.

[0055] Preferably, the second barb 142 may be provided only on the side opposite to the side wall of the recessed space 11 where the inspection door 14 is hinged, so as to facilitate the opening and closing of the inspection door 14 .

[0056] Preferably, a second rubber strip is provided between the fixing frame 13 and the inspection door 14 to further seal the gap between the inspection door 14 and the fixing frame 13 to achieve the effects of heat preservation and noise reduction.

[0057] Specifically, a first notch and a second notch are formed on the top surface of the fixing frame 13 and the side near the inspection door 14, and a first protrusion and a second protrusion matching the first notch and the second notch are formed at both ends of the second rubber strip, respectively. The first protrusion and the second protrusion are correspondingly inserted into the first notch and the second notch, so that the second rubber strip fits the top surface and the corresponding side of the fixing frame 13. This setting method enables the second rubber strip to fit the outer surface of the fixing frame 13 without warping and the like, and has better sealing performance.

[0058] The specific implementation method of the present invention is as follows:

[0059] The supporting member 12 is mounted on the inner wall of the recessed space 11, and the folded edge of the cover plate 17 is inserted into the hook portion 121 of the supporting member 12, so that the cover plate 17 covers the recessed space 11 near the opening and blocks the opening. Since the cover plate 17 is made of a sound-insulating aluminum plate, it has a certain sound-insulating effect.

[0060] Place the sound insulation board 16 on the cover plate 17 and install the fixing frame 13 on the top of the side wall of the recessed space 11;

[0061] One side of the access door 14 is hinged to the fixed frame 13, and the insulation board 15 is filled between the access door 14 and the sound insulation board 16;

[0062] The access door 14 is rotated downward so that the groove 141 on the access door 14 is buckled with the protrusion 131 on the fixed frame 13, and the second barb 132 on the access door 14 is hooked with the first barb 132 on the fixed frame 13. At this time, the access door 14 is fixedly buckled on the fixed frame 13, thereby closing the opening of the recessed space 11. In this way, the access door 14 can be tightly buckled on the fixed frame 13 without the problem of loosening, thereby achieving the effect of further heat preservation and noise reduction;

[0063] When the recessed space 11 needs to be opened, the access door 14 is rotated upward. The rotational force acting on the access door 14 causes the second hook 142 on the access door 14 to disengage from the first hook 132 of the fixed frame 13. The access door 14 is further rotated so that the groove 141 on the access door 14 disengages from the protrusion 131, thereby opening the access door 14. That is, a certain force needs to be applied to the access door 14 to open the access door 14.

[0064] The heat-insulating plate 15 and the sound-insulating plate 16 are removed, and the cover plate 17 is removed, thereby releasing the blockage of the opening of the recessed space 11 , and the construction personnel can inspect and repair the air-conditioning outdoor unit 21 .

[0065] Combine Figure 8 As shown, the present invention also provides a method for installing an indoor air conditioning structure with energy-saving and noise-proof performance, the method comprising the following steps:

[0066] Execute step S11. Install a cover plate 17 on the inner wall of the recessed space 11 near the opening to block the opening of the recessed space 11, and lay a sound insulation board 16 on the cover plate 17; then execute step S12.

[0067] Execute step S12. Hinge one side of the inspection door 14 to the top of the corresponding side wall of the recessed space 11, and fill the insulation board 15 between the inspection door 14 and the sound insulation board 16; then execute step S13

[0068] Execute step S13. Engage the other side of the inspection door 14 on the top of the corresponding side wall of the recessed space 11 to block the opening.

[0069] Furthermore, it also includes a supporting member 12 having an upwardly bent hook portion 121 formed at the bottom end and a fixing frame 13 provided with a first clamping member, the cover plate 17 is provided with a folded edge portion corresponding to the hook portion 121, and the inspection door 14 is provided with a second clamping member corresponding to the first clamping member;

[0070] Install the support member 12 along the inner wall of the recessed space 11 near the opening, and insert the folded edge of the cover plate 17 into the hook portion 121 accordingly, so that the cover plate 17 is mounted on the support member 12;

[0071] The fixing frame 13 is fixedly installed on the top of the side wall at the opening of the recessed space 11, and one side of the inspection door 14 is hinged to the corresponding side of the fixing frame 13. By rotating the inspection door 14, the second clamp is clamped into the first clamp, so that the inspection door 14 is buckled into the fixing frame 13, thereby blocking the opening.

[0072] Further, combined Figure 7 As shown, when installing the fixing frame 13, it also includes:

[0073] When the recessed space 11 is arranged along the building partition wall 111, that is, one side of the recessed space 11 is close to the facade, one side is close to the building partition wall 111, and the other two sides are built side walls. Since there is no position on the building partition wall 111 for installing the fixing frame 13, a support member 112 with an L-shaped cross-section is provided, and one side edge of the support member 112 is fitted and installed on the building partition wall 111, so that the other side edge of the support member 112 is located on the inner side of the recessed space 11, and the top of the support member 112 is flush with the top of the side wall of the recessed space 11, so that the side of the fixing frame 13 can be installed correspondingly on the support member 112.

[0074] The actual operation mode of the installation method provided by the present invention is as follows:

[0075] Taking the case where the recessed space 11 is attached to the building partition wall 111 as an example, one side of the support member 112 is fixedly connected to the building partition wall 111 with expansion bolts, and the other side forms a platform on the building partition wall 111. The top of the platform is flush with the top of the side wall of the recessed space 11.

[0076] The supporting member 12 is mounted on the inner wall of the recessed space 11, and the folded edge of the cover plate 17 is inserted into the hook portion 121 of the supporting member 12, so that the cover plate 17 covers the recessed space 11 near the opening and blocks the opening. Since the cover plate 17 is made of a sound-insulating aluminum plate, it has a certain sound-insulating effect.

[0077] Place the sound insulation board 16 on the cover plate 17 and install the fixing frame 13 on the top of the side wall of the recessed space 11;

[0078] One side of the access door 14 is hinged to the fixed frame 13, and the insulation board 15 is filled between the access door 14 and the sound insulation board 16;

[0079] The access door 14 is rotated downward so that the groove 141 on the access door 14 is buckled with the protrusion 131 on the fixed frame 13, and the second barb 132 on the access door 14 is hooked with the first barb 132 on the fixed frame 13. At this time, the access door 14 is fixedly buckled on the fixed frame 13, thereby closing the opening of the recessed space 11. In this way, the access door 14 can be tightly buckled on the fixed frame 13 without the problem of loosening, thereby achieving the effect of further heat preservation and noise reduction;

[0080] When it is necessary to open the opening of the recessed space 11, the inspection door 14 is rotated upward, and the rotational force acting on the inspection door 14 causes the second hook 142 on the inspection door 14 to disengage from the first hook 132 of the fixed frame 13. The inspection door 14 is continued to be rotated so that the groove 141 on the inspection door 14 disengages from the protrusion 131, thereby opening the inspection door 14. That is, a certain force needs to be applied to the inspection door 14 to open the inspection door 14.

[0081] The present invention has been described in detail above with reference to the embodiments of the accompanying drawings. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
