[0002] With the progress and development of society, people's pursuit of indoor comfort is increasing day by day, and energy-saving awareness is also increasing. Household fresh air fans not only have the functions of heat preservation, moisture retention, filtration and purification, but also have a compact structure and energy-saving efficiency, and are gradually becoming people's choice.

[0003] The conventional installation method for through-the-wall equipment similar to household fresh air fans is: pre-embed a steel casing in the wall, install the through-the-wall equipment in the steel casing, and then fill the space between the casing and the through-the-wall equipment with rock wool for sealing. This structure has the following shortcomings: the steel casing has greater thermal conductivity, which accelerates the heat exchange between indoors and outdoors; the steel casing has a smooth surface and is not easy to bond with the wall; the rock wool in the casing is prone to aging in an open environment, making it easy for gaps to appear in both places, resulting in additional indoor and outdoor air exchange. The above shortcomings increase the energy consumption of indoor air-conditioning systems. In extremely cold areas, if the airtightness and thermal insulation performance of the through-the-wall equipment installation structure are poor, frost and ice are prone to occur, causing damage to the equipment.

[0010] In a preferred embodiment, it also includes a rain shield; the rain shield is arranged at the outdoor side port of the sleeve; the rain shield is provided with a gas flow port in the area facing the tubular body.

[0011] In a preferred embodiment, the outdoor side port of the sleeve is flush with the tubular body; the outer surface of the air exchange device, the inner wall of the sleeve and the rain shield enclose a closed space, and the second insulation layer is arranged in the closed space.

[0012] In a preferred embodiment, it also includes a sealing ring; the outdoor side port of the tubular body does not contact the rain shield, and the sealing ring is provided at the end of the second insulation layer close to the outdoor side.

[0013] In a preferred embodiment, the waterproof layer on the outdoor side is a waterproof vapor-permeable membrane.

[0027] Embodiment 1

[0028] like Figure 1As shown, this preferred embodiment provides an airtight heat-insulating installation structure of a through-wall device, which is used to install the household fresh air blower 4 shown on the outer wall 1 shown, and the installation structure includes a UPVC casing 3, a first heat-insulating layer 6, a second heat-insulating layer 7, a waterproof vapor-permeable membrane 9, a waterproof vapor-isolating membrane 8, a mortar layer 10, a surface layer 12 and a rain shield 5. In this embodiment, the air exchange device is the household fresh air blower 4.

[0029] like Figure 2 As shown, a reserved hole 2 is provided through the outer wall 1 to provide space for installing the household fresh air fan 4. The axial direction of the reserved hole 2 is perpendicular to the outer wall 1, and the diameter is at least 100 mm wider than the outer diameter of the UPVC sleeve 3. The UPVC sleeve 3 is passed through the reserved hole 2, and both ends protrude from the lateral edges of the reserved hole 2. Rock wool is filled between the outer wall 1 and the UPVC sleeve 3 to serve as the first thermal insulation layer 6. In order to achieve a better thermal insulation effect, the UPVC sleeve 3 is coaxially arranged with the reserved hole 2 so that the thickness of the first thermal insulation layer 6 is the same at each location.

[0030] like Figure 1 As shown, the waterproof vapor barrier film 8 is provided on the indoor side of the first thermal insulation layer 6, and the waterproof vapor permeable film 9 is provided on the outdoor side to provide the same function as the waterproof layer. The waterproof vapor barrier film 8 is folded and pasted on the UPVC sleeve 3 at the position where it intersects with the UPVC sleeve 3, and extends at least 40mm along the axial direction of the UPVC sleeve 3. The waterproof vapor permeable film 9 is folded and pasted on the UPVC sleeve 3 at the position where it intersects with the UPVC sleeve 3, and extends to the outdoor side port of the UPVC sleeve 3. The waterproof vapor barrier film 8 and the waterproof vapor permeable film 9 are pasted on the outer wall 1 away from the UPVC sleeve 3, and the radial pasting length on the outer wall 1 is not less than 40mm.

[0031] The mortar layer 10 is paved on both sides of the exterior wall 1 and extends to the surface of the UPVC sleeve 3 to cover the waterproof vapor barrier membrane 8 and the waterproof vapor permeable membrane 9. In order to prevent the mortar layer 10 from falling off and affecting the normal operation of the waterproof vapor barrier membrane 8 and the waterproof vapor permeable membrane 9, a layer of alkali-resistant glass fiber mesh 11 can be laid in the mortar layer 10, close to the waterproof vapor barrier membrane 8 and the waterproof vapor permeable membrane 9, to reinforce the mortar layer 10 in the area. On the outside of the mortar layer 10, that is, on the side away from the exterior wall 1, a surface layer 12 is also provided. In this embodiment, the surface layer 12 is whitewashed with putty on the indoor side and sprayed with waterproof material on the outdoor side. The specific material and thickness of the surface layer 12 are in accordance with the general construction standards for building engineering, and are not described in a restrictive manner in this article.

[0032] like Figure 1 As shown, the household fresh air fan 4 is composed of a cap-shaped body 401 and a tubular body 402 coaxially, and the whole is a "rivet"-like structure. The cap-shaped body 401 is installed on the indoor side of the exterior wall 1, and abuts against the port of the UPVC sleeve 3 from the side. The tubular body 402 is inserted into the UPVC sleeve 3, and the inner diameter of the UPVC sleeve 3 is at least 60 mm wider than the outer diameter of the tubular body 402. Rock wool is filled between the tubular body 402 and the UPVC sleeve 3 to serve as the second thermal insulation layer 7. In order to achieve a better thermal insulation effect, the tubular body 402 is coaxially arranged with the UPVC sleeve 3 so that the thickness of the second thermal insulation layer 7 is uniform at each location.

[0033] On the outdoor side, the mounting structure is provided with the rain shield 5 to prevent precipitation from entering the tubular body 402 of the household fresh air machine 4 and causing damage to the equipment. The middle of the rain shield 5 abuts against the outdoor port of the UPVC sleeve 3, and a gas flow port is provided in the area facing the tubular body 402. In this embodiment, the indoor port and the outdoor port of the UPVC sleeve 3 are both flush with the surface of the surface layer 12, so that when the cap-shaped body 401 and the rain shield 5 abut against the port of the UPVC sleeve 3, the outer periphery can be fixed on the surface of the surface layer 12.

[0034] like Figure 1 As shown, in this embodiment, the outdoor port of the UPVC casing 3 is flush with the port of the tubular body 402. In this way, the outer surface of the household fresh air fan 4 and the inner wall of the UPVC casing 3 and the rain shield 5 enclose a closed space. No additional sealing treatment is required to ensure that the second thermal insulation layer 7 is in an ideal working environment.

[0035] In order to make the technical solution of this embodiment clearer and easier to understand, the construction steps of the installation structure are briefly described below:

[0036] (1) The reserved hole 2 is provided at a position on the outer wall 1 where the household fresh air fan 4 is to be installed;

[0037] (2) The UPVC sleeve 3 is auxiliary fixed in the reserved hole 2, and rock wool is densely filled between the reserved hole 2 and the UPVC sleeve 3 to serve as a first insulation layer 6;

[0038] (3) The waterproof vapor barrier film 8 is attached to the indoor surface of the second thermal insulation layer 7, and the waterproof vapor permeable film 9 is attached to the outdoor surface of the second thermal insulation layer 7; the waterproof vapor barrier film 8 and the waterproof vapor permeable film 9 are both extended and attached to the outer wall of the UPVC casing 3 and the outer wall 1;

[0039] (4) a layer of the alkali-resistant glass fiber mesh 11 is hung on the outside of the waterproof vapor barrier membrane 8 and the waterproof vapor permeable membrane 9, and then the mortar layer 10 is laid to cover the exterior wall 1 and the waterproof vapor barrier membrane 8 and the waterproof vapor permeable membrane 9;

[0040] (5) After the mortar layer 10 is formed, the surface layer 12 is constructed: the indoor side is whitened with putty, and the outdoor side is sprayed with waterproof material; the total thickness of the mortar layer 10 and the surface layer 12 needs to be controlled so that the surface of the surface layer 12 is flush with the end of the UPVC casing 3;

[0041] (6) The tubular body 402 of the household fresh air fan 4 is sleeved into the UPVC casing 3 from the indoor side until the cap-shaped body 401 abuts against the end of the UPVC casing 3, and then the household fresh air fan 4 is installed and fixed on the UPVC casing 3 and the surface layer 12; then, the area between the UPVC casing 3 and the tubular body 402 is densely filled with rock wool as a second insulation layer 7;

[0042] (7) The rain shield 5 is abutted against the outdoor port of the UPVC sleeve 3 and fixed on the outdoor surface layer 12.

[0043] Embodiment 2

[0044] like Figure 2 As shown, the difference between the airtight heat-insulating installation structure of the through-wall equipment provided in this embodiment and the embodiment 1 is that the outdoor port of the tubular body 402 does not contact the rain shield 5, so the outer surface of the household fresh air fan 4 and the inner wall of the UPVC casing 3 and the rain shield 5 cannot enclose a closed space. To ensure that the second heat-insulating layer 7 works in a sealed environment, a sealing ring 13 is provided at the end of the second heat-insulating layer 7 close to the outdoor side.

[0045] Accordingly, during installation, after rock wool is densely filled between the tubular body 402 and the UPVC sleeve 3 to form the second thermal insulation layer 7, the sealing ring 13 needs to be provided at the end of the second thermal insulation layer 7 close to the outdoor side.

[0046] Except for the above differences, other parts of the airtight heat-insulating installation structure of the wall-penetrating equipment provided in this embodiment are the same as those in the first embodiment.

[0047] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
