[0002] Duct air conditioners are hidden air conditioners, commonly known as duct units. Duct units have a wide range of applications due to their low price, relatively high unit energy efficiency, and ease of introducing fresh air. The typical structure of a duct unit can be found in the Chinese patent documents with announcement numbers CN209042572U and CN203718930U. The evaporator of a duct unit often uses a V-shaped evaporator core, and windshields are generally not installed on both sides of its length. Only evaporator side panels for installing the evaporator refrigerant tube and an evaporator mounting plate for installing the evaporator as a whole are fixedly provided. The evaporator side panels include an upper evaporator side panel and a lower evaporator side panel. The lower surface of the upper evaporator side panel and the upper surface of the lower evaporator side panel are combined to form a V-shaped structure that matches the inner wall of the V-shaped evaporator core.

The evaporator is fixedly installed in the outer casing of the duct unit through the evaporator mounting plate.
[0003] During their research, the applicant discovered that due to loose air duct seals on the left and right sides of the evaporator, some air escaped from the sides, directly affecting heat exchange efficiency and generating a certain amount of noise (installing a windshield can reduce ducted air conditioner noise by 1 to 2 decibels). Traditional windshield mounting methods use screws combined with additional sheet metal to secure the ducted air conditioner to the mounting structure, resulting in poor sealing and low installation efficiency.

DETAILED DESCRIPTION
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] like Figures 1 to 7 As shown, the duct air conditioner windshield 10 described in the utility model includes a windshield body, one large surface of which is the windshield duct surface, and the windshield duct surface is vertically arranged and located on the left or right side of the windshield body as a reference state. The rear side surface of the windshield body is the duct mounting plate docking surface 11, and the front side surface is the evaporator matching mounting surface 12. The evaporator matching mounting surface 12 has at least a V-shaped structure that matches the V-shaped cross-section of the inner cavity of the evaporator core (preferably, the portion where the extended matching portion 131 of the crack groove 13 described later is located is also provided), and the evaporator matching mounting surface 12 is provided with a crack groove 13 for clamping the evaporator side panel 21. Whether the windshield's air duct surface is located on the left or right side of the windshield body is determined by the state of the ducted air conditioner windshield 10 after installation. The front side of the windshield body serves as the evaporator mounting surface 12, which is equivalent to the air outlet being located on the front side of the ducted air conditioner after the windshield 10 is installed. The windshield's air duct surface is the outer surface of the ducted air conditioner windshield 10 facing the inner cavity of the evaporator 20. In the specific implementation of the ducted air conditioner windshield 10 described in the present invention, its evaporator mounting surface 12 is directly engaged with the evaporator side panel 21 through the slit groove 13 to form a sealed structure, which is both convenient and quick to assemble and ensures a good air duct sealing effect.
[0026] To facilitate assembly, raised snap-in ribs 16 are provided on either side of the inner wall of the slit groove 13. These ribs extend in the same direction as the length of the slit groove 13. In this solution, the snap-in ribs 16 effectively clamp the evaporator side panels 21 from both sides, securing the ducted air conditioner windshield 10 to the evaporator side panels 21. More specifically, the inner wall of the slit groove 13 forms a clearance fit with the evaporator side panels 21, while the gaps formed by the snap-in ribs 16 create an interference fit with the evaporator side panels 21.
[0027] To facilitate assembly, several guide blocks 17 are fixedly mounted on the evaporator mounting surface 12 on the side of the slit groove 13 away from the windshield air duct surface. The guide blocks 17 have guide surfaces 171 on the side near the slit groove 13, which guide the evaporator side panels 21 during the engagement process between the slit groove 13 and the evaporator side panels 21. It should be understood that the specific arrangement of the guide blocks 17 should take into account the placement of the evaporator copper tubes (small U-tubes), and the two should not interfere with each other.
[0028] To further improve structural reliability, one end of the crack groove 13 close to the lower side of the windshield body has an extended matching portion 131 that matches the rear end surface of the evaporator side plate 21.
[0029] To further enhance structural reliability, the upper side of the windshield body features a mating portion for the air conditioner's top assembly. This portion includes a mating surface 141 of the duct mounting plate's upper bent edge, located near the duct mounting plate's mating surface 11, and a thermal insulation foam mating surface 142, located near the evaporator's mating surface 12. A positioning groove 143 is provided on the mating surface 141. Ducted air conditioners typically have thermal insulation foam 50 installed above the evaporator 20. The mating surface 142 and the thermal insulation foam 50 enhance the sealing performance at the top. The duct mounting plate 40 typically features a mating, bent edge 41 for mating with the ducted air conditioner's top plate 60. This edge 41 is provided with a recessed groove to mate with the studs on the ducted air conditioner's top plate 60. The positioning groove 143 in the ducted air conditioner's windshield 10 mates with the recessed groove on the duct mounting plate's upper bent edge 41, further enhancing the sealing performance at the top.
[0030] To further improve structural reliability, the lower side of the windshield body has a water tray mating portion. The water tray mating portion includes a support and positioning portion for mating with the inner cavity structural surface of the water tray 30 and a wiring groove portion 153 for mating with the upper end surface of the side wall of the water tray 30. The support and positioning portion includes a support slope 151 for mating with the protrusion at the bottom of the inner cavity of the water tray 30 and a vertical positioning plane 152 for mating with the side wall of the water tray 30. After the support slope 151 and the vertical positioning plane 152 are provided, the bottom support performance of the duct air conditioner windshield 10 can be improved by the water tray 30, while the sealing performance of the bottom position can be improved. The wiring groove portion 153 is used to cooperate with the upper end surface of the side wall of the water tray 30 to form a wiring slot for the electric heating wire to pass through. The wiring groove portion 153 can be formed by splicing multiple arc-shaped surfaces with different radii to match the passage of electric heating wires of different sizes.
[0031] To facilitate processing and assembly, the air duct surface of the wind shield is preferably a vertical plane; the docking surface 11 of the air duct mounting plate is also preferably a vertical plane.
[0032] The main structure of the ducted air conditioner in the present invention can be implemented with reference to the existing technology, and mainly includes an evaporator 20, a water receiving tray 30 and an air duct mounting plate 40. The evaporator 20 includes a V-shaped evaporator core, which is placed horizontally, and the opening of the V-shaped evaporator core is facing the air inlet direction; the left and right sides of the V-shaped evaporator core are respectively fixed with evaporator side plates 21 for installing the evaporator refrigerant tube; the evaporator side plates 21 include an upper evaporator side plate 211 and a lower evaporator side plate 212, and the lower surface of the upper evaporator side plate 211 and the upper surface of the lower evaporator side plate 212 are combined to form a V-shaped structure that matches the inner wall of the V-shaped evaporator core, and the top of the upper evaporator side plate 211 and the lower evaporator side plate 212 are respectively fixed with the upper evaporator side plate 211 and the lower evaporator side plate 212. The bottom of the side panel 212 is fixedly connected to the evaporator mounting plate 22, and the evaporator 20 is fixedly mounted in the outer casing of the duct machine through the evaporator mounting plate 22. The water collecting tray 30 is fixedly arranged below the evaporator 20, and the air duct mounting plate 40 is fixedly arranged on the opening side of the V-shaped evaporator core. Wind shields are fixedly installed on the left and right sides of the V-shaped evaporator core, and at least one side of the wind shield adopts the duct machine wind shield 10 described above in the present invention. The air duct mounting plate docking surface 11 of the duct machine wind shield 10 contacts the front side of the air duct mounting plate 40, and the upper evaporator side panel 211 and the lower evaporator side panel 212 respectively form a snap fit with the crack groove 13 of the duct machine wind shield 10.
[0033] For details, please refer to Figure 6 and Figure 7Duct air conditioners usually require an electrical control box 80 to be arranged on one side of the evaporator 20. Therefore, the side of the duct air conditioner housing where the electrical control box 80 is arranged usually has a larger cavity structure. The sealing performance requirements of the windshield on this side during installation are also higher than those on the other side (the side without the electrical control box 80). Accordingly, the windshield on the side where the electrical control box 80 is installed preferably adopts the duct air conditioner windshield 10 described above in the present invention. The windshield on the other side can adopt the duct air conditioner windshield 10 described above in the present invention, or a conventional windshield 90. The conventional windshield 90 is usually a sheet metal part that can be connected and fixed to the upper evaporator side panel 211 and the lower evaporator side panel 212 respectively by screw connection. Of course, additional fixed connection points can be added according to actual conditions.
[0034] During the specific implementation of the present invention, the overall assembly process is basically the same as that of the prior art. It is only necessary to pre-connect the duct unit wind shield with the evaporator side panel through its crack groove before installing the evaporator as a whole. After the evaporator as a whole is installed in the duct unit, the water receiving tray 30 is installed.
