DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the scope of protection of the present application.

[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0020] The present application provides an air port frame assembly and a processing method, which can effectively solve the condensation problem of the air port frame.

[0021] Reference Figure 1 The present application discloses an air port frame assembly, the cross section of the air port frame assembly is L-shaped, and the air port frame assembly comprises an inner air port frame 1, an outer air port frame 2 and a heat insulation strip 3. The inner air port frame 1 is used to be connected with an air conditioner cold air outlet pipe, and the end of the inner air port frame 1 is provided with an inner glue injection groove 11. The outer air port frame 2 is exposed on a mounting surface, and the end of the outer air port frame 2 is provided with an outer glue injection groove 21. The inner air port frame 1 and the outer air port frame 2 are arranged at intervals, the heat insulation strip 3 is installed between the inner glue injection groove 11 and the outer glue injection groove 21, and is used to connect the inner air port frame 1 and the outer air port frame 2.

[0022] The inner frame 1 and outer frame 2 of the air vent do not directly contact each other, and the inner frame 1 can also be equipped with a clip 13 for installing louvers. The installation position of the air vent frame assembly varies depending on the air supply method of the air conditioner, and it is mainly installed under the ceiling or on the side. Since the inner frame 1 is directly connected to the air duct system, it will be directly blown by cold air. The outer frame 2 is exposed on the ceiling or wall surface, used to connect the air vent frame assembly and play a certain decorative role. During the air supply, the air conditioner's cold air enters the room after passing through the inner frame 1. Because the indoor hot air is difficult to enter the inner frame 1 during the air supply, the surface of the inner frame 1 will not form too much condensation. The inner frame 1 and outer frame 2 are not directly connected, and a heat insulation strip 3 is installed between them, which can effectively prevent the cold air of the inner frame 1 from being transferred to the outer frame 2, thereby effectively reducing the condensation phenomenon of the outer frame 2.

[0023] In this embodiment, both the inner frame 1 and the outer frame 2 of the air vent are made of aluminum alloy. The cross-sectional shape of the inner glue injection groove 11 and the outer glue injection groove 21 is C-shaped, and the openings of the inner glue injection groove 11 and the outer glue injection groove 21 are arranged opposite to each other. The heat insulation strip 3 is connected to the inner glue injection groove 11 and the outer glue injection groove 21 to ensure that the relative position of the inner frame 1 and the outer frame 2 of the air vent remains stable. As a further optimization, the cross-sectional shape of the inner glue injection groove 11 and the outer glue injection groove 21 can also be other forms, as long as the heat insulation strip 3 can be stably connected to the inner frame 1 and the outer frame 2 of the air vent.

[0024] The thermal insulation strip 3 is a two-component polyurethane composite material, mainly composed of a polyol composite material and an MDI prepolymer composition. The polyol composite material consists of polyols, catalysts, etc., and the MDI prepolymer composition is a prepolymer of diphenylmethane diisocyanate. The resulting thermal insulation material has certain structural strength and toughness, while also meeting fire protection requirements. Thus, the thermal insulation strip 3 meets the requirements for thermal insulation, installation strength, and fire protection.

[0025] In this embodiment, a guide plate 4 is provided at one end of the inner frame 1 of the air vent away from the inner glue injection groove 11. The guide plate 4 extends towards the air vent and protrudes from the air duct surface of the inner frame 1 of the air vent. The angle between the guide plate 4 and the air duct surface of the inner frame 1 of the air vent is an acute angle, preferably 15 degrees to 60 degrees. Before the air conditioning cold air passes through the inner frame 1 of the air vent, the air conditioning cold air will be concentrated in the middle of the air duct formed by the inner frame 1 of the air vent under the action of the guide plate 4, thereby minimizing the transfer of cold air between the air conditioning cold air and the inner frame 1 of the air vent, further reducing the amount of cold air transferred from the inner frame 1 of the air vent to the outer frame 2 of the air vent, thereby further reducing the probability of condensation on the surface of the outer frame 2 of the air vent.

[0026] In this embodiment, the inner frame 1 of the air vent is provided with an inner slot 12 for connecting with the air conditioning duct via a spring at one end away from the inner glue injection groove 11; the inner frame 1 of the air vent is also provided with a slot 13 for installing louvers on the side away from the outer frame 2 of the air vent. Through the setting of the inner slot 12 and the slot 13, the assembled air vent frame assembly can be further installed with air conditioning ducts and louvers.

[0027] In this embodiment, an outer slot 22 is provided at the end of the outer frame 2 of the air vent away from the outer glue injection groove 21. The outer slot 22 is used to connect with the splicing plate. At least two outer frames 2 of the air vent are connected by embedding the splicing plate into the outer slot 22. When the length of the outer frame 2 of the air vent does not meet the installation requirements, multiple outer frames 2 of the air vent need to be spliced ​​together. By setting the outer slot 22, multiple outer frames 2 of the air vent can be fixed by simply embedding the splicing plate into the outer slot 22, and the coaxial mating relationship is satisfied.

[0028] This embodiment also includes a shielding strip 5, which is snap-fitted between the inner frame 1 and the outer frame 2 of the air vent. A protrusion for snapping the shielding strip 5 is located below the inner glue groove 11 of the inner frame 1, and a corresponding protrusion is also provided on the outer frame 2. The shielding strip 5 has a certain decorative effect. As a further optimization, the cross-section of the shielding strip 5 is L-shaped, and dot-shaped protrusions are provided on its vertical sides, thereby forming point contact between the shielding strip and the inner frame 1 of the air vent, reducing wind... The efficiency of cold air transfer between the inner frame 1 and the shielding strip 5 is improved. The horizontal edge of the shielding strip 5 is provided with at least two tabs protruding upwards. Corresponding slots are provided on the inner frame 1 and the outer frame 2 of the air vent. The shielding strip 5 is fixedly installed on the inner frame 1 and the outer frame 2 of the air vent by engaging the tabs in the slots. The shielding strip 5 mainly shields the exposed part of the heat insulation strip 3 by the horizontal edge of the shielding strip 5, improving the aesthetics of the air vent frame assembly. At the same time, it can also prevent the cold air from the inner frame 1 of the air vent from being transferred to the outer frame 2 of the air vent.

[0029] In this embodiment, both the inner frame 1 and the outer frame 2 of the air vent are coated with an anti-condensation coating, which further enhances the anti-condensation effect.

[0030] refer to Figures 2 to 3 This invention provides a method for processing an air vent frame assembly, using a split inner and outer air vent strip as processing parts. The inner air vent frame 1 includes multiple inner air vent strips connected end-to-end to form a frame structure, and the outer air vent frame 2 includes multiple outer air vent strips connected end-to-end to form a frame structure. An auxiliary connecting profile 6 is provided between the edge of the inner glue injection groove of the inner air vent strip and the edge of the outer glue injection groove of the outer air vent strip. The inner air vent strip, the outer air vent strip, and the auxiliary connecting profile 6 together form a glue injection cavity 7. A glue injection port is reserved at the top of the glue injection cavity 7. The method is characterized by the following steps: The heat insulation adhesive is filled into the injection cavity 7 through the injection port, and the cured heat insulation adhesive forms the heat insulation strip 3. After the heat insulation adhesive has cured, cut off the auxiliary connecting profile 6 and disconnect the metal connection between the inner edge strip and the outer edge strip of the air vent, so that the inner edge strip and the outer edge strip of the air vent are spaced apart. The shielding strip 5 is snapped into place between the inner edge strip and the outer edge strip of the air vent to obtain the air vent frame unit; The air vent frame components are obtained by connecting the individual air vent frame pieces end to end. When connecting, the inner edge strips of the air vent are connected to form the inner edge 1 of the air vent, and the outer edge strips of the air vent are connected to form the outer edge 2 of the air vent. Finally, sealant is applied to the joints of the individual air vent frame units to seal them, or welding is used to fix them, thus forming the air vent frame assembly. It also includes installing splicing panels: installing the splicing panels in the outer slots 22 of the outer edge strips of adjacent air vents and fixing them in place.
