Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and more specifically, relates to an air duct machine. Background Art

[0002] Due to the need for a larger heat dissipation area for the heat exchange function of the air conditioner heat exchanger, it is often equipped with a relatively weak fin structure, resulting in the need to disassemble structural components inside the existing air conditioner to leave a larger operating space to avoid damaging the fins during the installation process. Moreover, the disassembled structures are usually fixedly connected by screws, which affects the assembly efficiency.

[0003] On the other hand, because the heat exchanger assembly requires thermal processing such as welding during the manufacturing process, the end fixing structure of the heat exchanger of the current air conditioner often uses a metal material end plate, which is fixedly connected to the outer shell sheet metal part through metal fasteners, making the communication path between the heat exchanger and the outer shell sheet metal part metal. Since metal has good thermal conductivity, when the air conditioner operates in the cooling mode, the cold quantity is quickly transferred to the air conditioner outer shell, resulting in the outer shell temperature being lower than the dew point temperature, thus causing the problem of condensation on the air conditioner outer shell.

[0047] Referring to Figure 1 , the air duct machine of the present invention is an indoor air conditioner, which is connected to the outdoor unit through a pipe, and includes a housing 1, a fan system, and a heat exchange system. The housing 1 is used to form a cavity, accommodate the fan system and the heat exchange system, and assist the fan system and the heat exchange system to realize the circulation adjustment of indoor air.

[0048] Referring to Figure 1 and Figure 2 , the housing 1 includes end side plates and a bottom plate 11, which respectively form the left and right side end walls and the bottom wall of the housing 1.

[0049] The heat exchange system includes a heat exchanger 6, which is located above the bottom plate 11 and is connected to the end side plate through the connection of a slideway 21 and a slide rail 31. The heat exchanger 6 is restricted within the slideway 21 during the installation process, avoiding contact with structural components outside the slideway 21, reducing the probability of damage to the fins during the installation process, reducing the defective rate, thereby reducing costs and improving the user experience.

[0050] Referring to Figure 1 , Figure 2 and Figure 3 , the connection structure of the slideway 21 and the slide rail 31 is specifically as follows.

[0051] The housing 1 includes a first side plate 12 and a second side 14, which respectively form the right wall and the left wall of the cavity formed by the housing 1; a vertical slideway 21 is provided on the inner side of the second side plate 14.

[0052] A slide rail 31 adapted to be connected to the above-mentioned slideway 21 is provided at one end of the heat exchanger 6, and it is connected to the slideway 21.

[0053] A pipe installation hole 121 is provided on the first side plate 12; a pipe 61 is fixedly connected to one end of the heat exchanger 6, and it passes through the pipe installation hole 121 and is installed in the pipe installation hole 121 for the preliminary positioning of the installation of the heat exchanger 6.

[0054] During installation, first, the pipe 61 is installed in the pipe installation hole 121 to preliminarily position one end of the heat exchanger 6 in the pipe installation hole 121; then, the lower end of the slide rail 31 is inserted into the slideway 21 from the upper end of the slideway 21 and moves downward to be connected to the slideway 21, realizing the preliminary fixation of the heat exchanger 6 in the housing 1.

[0055] Referring to Figure 1 , Figure 2 and Figure 3A first buckle 22 is provided on the inner side of one end of the slideway 21; accordingly, a first slot 32 adapted to be connected with the first buckle 22 is provided at a position corresponding to the first buckle 22 on the slide rail 31; when the slideway 21 is connected to the slide rail 31, the first buckle 22 is connected to the first slot 32 by clamping. The slideway is fixedly connected to the slide rail, so that the heat exchanger 6 is fixed in both the horizontal direction and the vertical direction.

[0056] As a specific embodiment of the slideway 21, refer to Figure 1 , Figure 2 and Figure 3 The slideway 21 is a vertical groove, which includes a first side wall and a second side wall, which respectively constitute two side walls of the groove.

[0057] One end of the first side wall is configured as a free end, and a first buckle 22 is disposed on the inner side of the free end.

[0058] Preferably, the free end is arranged at the end of the slideway 21 away from the bottom plate 11, that is, at the end of the slideway 21 where the slide rail 31 is connected; if the heat exchanger 6 needs to be disassembled, the first buckle 22 is conveniently operated to disengage it from the first slot 32, so that the heat exchanger 6 is freed from the vertical limit, and finally the heat exchanger 6 is moved upward to complete the disassembly.

[0059] Preferably, refer to Figure 1 , Figure 2 and Figure 3 The slide 21 includes a first end and a second end; the first end is an end away from the bottom plate 11, which is configured as a flared opening 211; when the slide 21 is connected to the slide rail 31, the slide rail 31 is inserted into the slide 21 from the first end, which has a guiding effect on the insertion of the slide rail 31, facilitates the connection between the slide 21 and the slide rail 31, and improves the connection efficiency.

[0060] Preferably, a handle 23 is provided at the end of the first side wall of the first end, and is used to pull the handle 23 to disengage the first buckle 22 from the first slot 32 when disassembling the heat exchanger 6, so as to facilitate the disassembly of the heat exchanger 6.

[0061] Preferably, the handle 23 is a concave arc-shaped structure extending outward from the end of the first side wall of the first end, so that it is more convenient and comfortable to pull.

[0062] Reference Figure 1 , Figure 2 and Figure 3 , the slide 21 is a U-shaped groove; in order to fix the slide rail 31 in the slide rail 21 and prevent the slide rail 21 from escaping longitudinally due to lateral escaping, a baffle 212 is provided on the outer side of the first side wall and / or the second side wall at the second end, and the outer side of the slide rail 31 relative to the slide rail 21 is located on the inner side of the baffle 212.

[0063] Preferably, a vertical groove 311 is provided on the outer side of the slide rail 31 relative to the slideway 21; the baffle 212 is located within the groove 311.

[0064] Preferably, the baffle 212 is provided on the outer side of the first side wall at the second end.

[0065] A limiting plate 213 is provided at the end of the second end of the slideway 21 to prevent the slide rail 31 from continuing to slide when it reaches the end of the slideway 21; the end of the slide rail 31 is located inside the limiting plate 213. Embodiment

[0066] Refer to Figure 1 、 Figure 2 Figure 3 and Figure 4 , the air duct machine includes a housing end fixing member 2, a heat exchanger first fixing member 3, and a heat exchanger second fixing member 5.

[0067] The housing end fixing member 2 is located inside the second side plate 14 and is fixedly connected to the second side plate 14. The slideway 21 is provided inside the housing end fixing portion 41.

[0068] A gap 221 is provided on the outer side of the first side wall at the first end of the slideway 21, so that the end of the first side wall forms a free end.

[0069] Preferably, the gap 221 is a U-shaped gap, which includes a bottom; the first buckle 22 is located above the bottom, so that the first buckle 22 has sufficient space to connect to and disengage from the first slot 32.

[0070] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the heat exchanger first fixing member 3 is located at one end of the heat exchanger 6 and is fixedly connected to the heat exchanger 6, and the slide rail 31 is provided on its outer side.

[0071] The heat exchanger second fixing member 5 is fixedly provided at the other end of the heat exchanger 6 and is fixedly connected to the housing 1.

[0072] During installation, first, the pipe is installed in the pipe installation hole; the heat exchanger second fixing member 5 abuts against the housing 1. Then, the slide rail 31 of the heat exchanger first fixing member 3 slides into the slideway 21 from the first end of the slideway 21, so that the heat exchanger 6 is limited in the horizontal and vertical directions by the connection of the slide rail 31 and the slideway 21, enabling the heat exchanger 6 to be quickly positioned inside the housing 1. Next, when the lower end of the slide rail 31 slides into the bottom position of the slideway 21, the first buckle 22 is engaged with the first slot 32, fixing the heat exchanger 6 in the vertical direction relative to the housing end fixing member 2. Finally, the housing end fixing member 2 is fixedly connected to the housing 1.

[0073] The connection between the sliding rail 31 and the sliding track 21 and the connection between the first buckle 22 and the first slot 32 not only enable the heat exchanger 6 to be assembled and positioned quickly and installed quickly, but also reduce the number of screws used, reduce manual labor loss, and lower costs. In addition, the installation structure has fewer components to be disassembled and fewer screws are used, improving the assembly efficiency.

[0074] Preferably, the housing end fixing member 2, the first heat exchanger fixing member 3, and the second heat exchanger fixing member 5 are all made of plastic or plastic material, so that less heat or cold on the heat exchanger 6 is transferred to the housing, reducing heat loss.

[0075] Specifically, the housing end fixing member 2 is fixedly connected to the metal housing 1; the first heat exchanger fixing member 3 is fixedly arranged at one end of the heat exchanger 6 and is fixedly connected to the heat exchanger 6; and the housing end fixing member 2 and the first heat exchanger fixing member 3 are fixedly connected through the connection between the sliding track 21 and the sliding rail 31 and the connection between the first buckle 22 and the first slot 32, so that one end of the heat exchanger 6 is not in direct contact with the housing 1, but is connected to the housing 1 through the non-good heat-conducting housing end fixing member 2 and the first heat exchanger fixing member 3, reducing heat loss.

[0076] The other end of the heat exchanger 6 is fixedly connected to the housing 1 through the second heat exchanger fixing member 5, so that the other end of the heat exchanger 6 is not in direct contact with the housing 1, but is connected to the housing 1 through the non-good heat-conducting second heat exchanger fixing member 5, reducing heat conduction and heat loss.

[0077] Since the heat transfer of plastic and plastic is worse than that of metal, the heat exchanger 6 and the housing 1 are fixedly connected through the plastic or plastic housing end fixing member 2, the first heat exchanger fixing member 3, and the second heat exchanger fixing member 5, so that less cold or heat on the heat exchanger 6 is transferred to the housing 1, reducing energy loss.

[0078] Especially when the air conditioner is refrigerating, less cold is transferred to the housing 1, making the temperature of the housing 1 higher than the water vapor condensation temperature, reducing the degree of water condensation on the housing 1, and improving the user experience.

[0079] Of course, other materials with sufficient strength and low heat transfer can be used for the installation components at both ends of the heat exchanger 6, namely, the housing end fixing member 2, the first heat exchanger fixing member 3, and the second heat exchanger fixing member 5. That is, using other materials with sufficient strength and low heat transfer still belongs to the protection scope of the present invention.

[0090] Preferably, a limiting strip 53 is provided at one end of the second fixing member 5 of the heat exchanger, and one end edge of the fixing portion 41 is located inside the limiting strip 53 to limit the fixing portion 41, making the connection and positioning between the second buckle 51 and the second card slot 411 easier and more convenient, and improving the installation efficiency.

[0091] Preferably, the clip 521 is a groove adapted to be installed on both sides of the opening hole 412, one side wall of the groove is the second fixing member 5 of the heat exchanger, and the other side wall and the bottom of the groove are fixedly connected to the positioning post 52.

[0092] Preferably, through holes are provided at positions corresponding to the groove walls on the second fixing member 5 of the heat exchanger, which facilitates the installation of the fixing portion 41 and increases the degree of tight fit between the fixing portion 41 and the clip 521.
