Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to an air conditioning unit. Background Technology

[0002] Currently, the air supply impeller of the air conditioner cabinet sends airflow from the lower part of the air duct to the upper area. Then the airflow passes through the air duct of the casing and blows out from the air outlet on the front side of the cabinet. During the entire air supply process, the airflow needs to change 90 degrees to blow out from the air outlet, which results in a larger air supply volume in the upper area of ​​the air outlet and a smaller air supply volume in the lower area, resulting in poor air supply uniformity.

[0003] A related technology includes an air conditioner cabinet unit, comprising an air outlet and an axial flow fan. The axial flow fan is located below the air outlet, and an air outlet is provided on the front side of the air outlet. An air outlet duct is formed inside the air outlet, connecting to the air outlet. The air outlet is characterized by having an air guide assembly inside the air outlet, the air guide assembly including an air guide plate, the air guide plate dividing the air outlet duct into two sub-ducts in the front-rear direction, thereby improving the uniformity of air outlet.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] The airflow in the front sub-duct will still flow upward along the air outlet and blow out from the upper area of ​​the air outlet. The uniformity of airflow cannot be improved. Moreover, setting up two sub-ducts at the front and back will sacrifice the airflow volume of the duct, reduce the air volume, make the duct structure more complicated, and increase the cost. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides an air conditioning unit that improves the uniformity of airflow from the air outlet, ensures airflow volume in the duct, simplifies the duct structure, and reduces costs.

[0008] In some embodiments, an air conditioning unit includes a housing and an air duct. The housing includes an air duct and an air outlet. The air duct is disposed inside the housing, and the air outlet is located on the side wall of the housing, with the plane of the air outlet being parallel to the flow direction of the air duct. The air duct is disposed on the inner wall of the air duct corresponding to the windward side of the air outlet, and is capable of guiding part of the airflow in the air duct to the leeward side area of ​​the windward side of the air outlet for blowing out.

[0009] The air conditioner unit provided in this embodiment can achieve the following technical effects:

[0010] Because the plane of the air outlet is parallel to the flow direction of the duct, most of the airflow in the duct will flow to the leeward side of the air outlet and be blown out, resulting in poor airflow uniformity. Therefore, by setting an air-guiding groove on the inner wall of the duct corresponding to the windward side of the air outlet, some of the airflow in the duct is guided by the air-guiding groove to be blown out from the leeward side of the windward side of the air outlet when it flows through the windward side of the air outlet, thereby improving the airflow uniformity. The air-guiding groove occupies less space in the duct, ensuring the airflow volume of the duct, simplifying the duct structure, and reducing costs.

[0035] Combination Figure 1-14As shown, this embodiment of the present disclosure provides an air conditioning unit, including: a housing 100 and an air duct 200. The housing 100 includes an air duct 110 and an air outlet 120. The air duct 110 is disposed inside the housing 100, and the air outlet 120 is located on the side wall of the housing 100, and the plane of the air outlet 120 is parallel to the flow direction of the air duct 110. The air duct 200 is disposed on the inner wall of the air duct 110 corresponding to the windward side of the air outlet 120, and can guide part of the airflow in the air duct 110 to the leeward side area of ​​the windward side of the air outlet 120 and blow it out.

[0036] The air conditioner unit provided in this embodiment has a poor air outlet uniformity because the plane of the air outlet 120 is parallel to the flow direction of the air duct 110. Most of the airflow in the air duct 110 flows to the leeward side of the air outlet 120 and is blown out. Therefore, by setting an air guide groove 200 on the inner wall of the air duct 110 corresponding to the windward side of the air outlet 120, some of the airflow in the air duct 110 is guided by the air guide groove 200 to be blown out from the leeward side of the windward side of the air outlet 120 when it flows through the windward side of the air outlet 120, thereby improving the air outlet uniformity. The air guide groove 200 occupies less space in the air duct 110, ensuring the airflow volume of the air duct 110, simplifying the structure of the air duct 110, and reducing costs.

[0037] Combination Figure 2 As shown, in some embodiments, the air outlet 120 is divided into a first air outlet area 121 and a second air outlet area 122 along the flow direction of the air duct 110. The second air outlet area 122 is located on the windward side of the first air outlet area 121, and the leeward side of the windward side of the air outlet 120 is the second air outlet area 122. Since the plane of the air outlet 120 is parallel to the flow direction of the air duct 110, the airflow in the air duct 110 needs to change its flow direction by 90 degrees to flow out of the air outlet 120. There is a difference in the air volume of the areas corresponding to the windward side and the leeward side of the air outlet 120 along the flow direction of the air duct 110. In order to represent the air outlet area of ​​the air outlet 120, the air outlet 120 is divided into a first air outlet area 121 and a second air outlet area 122 along the flow direction of the air duct 110. Most of the airflow in the air duct 110 flows out from the first air outlet area 121. Therefore, an air guide groove 200 is provided on the inner wall of the air duct 110 corresponding to the windward side of the air outlet 120. When the airflow flows through the air guide groove 200, the airflow is guided to the second air outlet area 122 and blown out, that is, guided to the leeward side area of ​​the air outlet 120, thus improving the overall air outlet uniformity of the air outlet 120.

[0038] Specifically, the housing 100 is vertically arranged, the air duct 110 is also vertically arranged inside the housing 100, and the air outlet 120 is arranged on the side wall of the housing 100 along the vertical direction, and the air outlet 120 is located in the upper region of the side wall of the housing 100. In this way, the housing 100 is vertically arranged, and the air outlet 120 is located on the side wall of the housing 100 along the vertical direction, so that the air conditioner can better deliver air into the room. By placing the air outlet 120 in the upper region of the side wall of the housing 100, the airflow in the air duct 110 flows from bottom to top, and after colliding with the upper inner wall of the air duct 110, the flow direction changes and it is blown out from the air outlet 120.

[0039] Specifically, the air outlet 120 is divided into a first air outlet area 121 and a second air outlet area 122 in the vertical direction. The second air outlet area 122 is located below the first air outlet area 121. The windward side of the air outlet 120 is the lower side of the air outlet 120, and the leeward side of the air outlet 120 is the upper side of the air outlet 120. Thus, since the airflow in the duct 110 flows from bottom to top, its flow direction changes after colliding with the upper inner wall of the duct 110 and it is blown out from the air outlet 120. Therefore, most of the airflow in the duct 110 will be blown out from the first air outlet area 121 located at the top, resulting in poor airflow uniformity at the air outlet 120. Therefore, an air guide groove 200 is provided on the inner wall of the duct 110 corresponding to the lower side of the air outlet 120, so that the airflow in the duct 110 is guided by the air guide groove 200 to the second air outlet area 122 when it flows through the lower side of the air outlet 120, thereby improving the airflow uniformity at the air outlet 120.

[0040] Specifically, the air duct 200 is located on the inner wall of the air duct 110 below the lower side of the air outlet 120. Since the airflow within the air duct 110 flows from bottom to top, the airflow first passes the lower side of the air outlet 120, then flows to the upper side of the air outlet 120 and collides with the upper inner wall of the air duct 110, changing its direction. Therefore, by placing the air duct 200 on the inner wall of the air duct 110 below the lower side of the air outlet 120, the airflow is better guided to the second air outlet area 122 of the air outlet 120 and blown out.

[0041] It is understandable that the flow area of ​​the first air outlet area 121 and the second air outlet area 122 are the same.

[0042] Combination Figure 3 As shown, in some embodiments, the air duct 200 is provided with a guide surface 210 inclined towards the second air outlet area 122. In this way, when the airflow in the air duct 110 flows through the air duct 200, the airflow is directed towards the second air outlet area 122 under the action of the guide surface 210, which further improves the air duct 200's air duct effect and balances the air volume of the first air outlet area 121 and the second air outlet area 122.

[0043] Specifically, the guide surface 210 is located in the upper region of the inner wall of the air intake trough 200, and the upper side of the guide surface 210 is connected to the lower side of the air outlet 120. In this way, when the airflow in the air duct 110 flows through the air intake trough 200, it is guided by the guide surface 210 and flows directly towards the lower side of the air outlet 120, and finally blown out from the second air outlet area 122, further improving the guiding effect.

[0044] Combination Figure 4 As shown, in some embodiments, a centrifugal fan 300 is installed in the lower region of the air duct 110, with the outlet end of the centrifugal fan 300 facing upwards and the inlet end facing the front sidewall of the housing 100. Thus, under the action of the centrifugal fan 300, indoor airflow is drawn in from the front sidewall of the housing 100 and blown from the outlet end towards the upper region of the air duct 110. The centrifugal fan 300 has a large airflow circulation volume, which can increase the airflow volume at the outlet 120 and accelerate the circulation of indoor airflow.

[0045] Optionally, the return air inlet is located on the front side wall of the housing 100 corresponding to the air inlet of the centrifugal fan 300. This allows indoor airflow to be drawn into the centrifugal fan 300 through the return air inlet, accelerating airflow circulation. Furthermore, since the front side wall of the housing 100 faces the indoor environment when the air conditioner is placed, placing the return air inlet on the front side wall of the housing 100 allows for better intake of indoor airflow.

[0046] Optionally, a heat exchanger 400 is also provided inside the air duct 110, located between the air outlet of the centrifugal fan 300 and the air outlet 120. In this way, the airflow blown out from the air outlet of the centrifugal fan 300 exchanges heat with the heat exchanger 400 as it flows through it, forming a heat exchange airflow. The heat exchange airflow is then blown out from the air outlet 120 to regulate the indoor ambient temperature.

[0047] Specifically, the heat exchanger 400 is inclined, and the flow surface of the air duct 110 is blocked. This increases the heat exchange area between the airflow and the heat exchanger 400, thereby improving the heat exchange efficiency.

[0048] Combination Figure 5 and Figure 6 As shown, in some embodiments, the air conditioner unit further includes a guide plate 500. The guide plate 500 is disposed at the upper end of the air intake slot 200, and an air outlet gap 510 is defined between the guide plate 500 and the air intake slot 200, facing the air outlet 120. Thus, by setting the guide plate 500 at the upper end of the air intake slot 200 and defining the air outlet gap 510 between the guide plate 500 and the air intake slot 200, the airflow in the air intake slot 200 is blown out along the air outlet gap 510 under the action of the guide plate 500, further improving the air intake and guiding effect and making the air outlet 120 more uniform.

[0049] Optionally, the air outlet gap 510 is oriented towards the second air outlet area 122. In this way, the air outlet gap 510 continuously blows the airflow in the air duct 200 towards the second air outlet area 122, thereby increasing the air volume of the second air outlet area 122, making the overall air volume of the air outlet 120 more uniform, and improving the uniformity of air outlet.

[0050] Optionally, the guide vane 500 is movably connected to the upper end of the air duct 200. By adjusting the tilt angle of the guide vane 500, the flow rate of the outlet gap 510 can be adjusted. In this way, the tilt angle of the guide vane 500 can be adjusted according to the air supply requirements, changing the flow area of ​​the outlet gap 510 defined between the guide vane 500 and the air duct 200, thereby adjusting the air volume of the outlet gap 510 to better meet different air supply requirements. Moreover, by adjusting the flow area of ​​the flow gap, the air velocity of the air blown out of the outlet gap 510 can also be adjusted, so that the second air outlet area 122 and the first air outlet area 121 present different air velocity, improving the air supply diversity of the air outlet 120.

[0051] Specifically, the guide plate 500 has a rectangular plate structure, and the upper end of the air duct 200 has a rectangular opening. The guide plate 500 is obliquely covered on the opening. Along the length direction of the guide plate 500, the length of the guide plate 500 is greater than the length of the opening. Both ends of the guide plate 500 in the length direction extend to the lower side of the air outlet 120. The lower side of the guide plate in the width direction is rotatably connected to the lower side of the air outlet 120. The other side of the guide plate is movably arranged towards the air outlet 120. There is a lifting mechanism 520 between the guide plate and the lower side of the air outlet 120. Thus, a rectangular plate-shaped guide plate 500 is placed over the upper opening of the air intake trough 200. Since the lower side of the air outlet 120 needs to fit the upper opening of the air intake trough 200, the lower side of the air outlet 120 has a notch. The guide plate 500 covers the opening, with its two ends extending across the opening to the lower side of the air outlet 120. The lower side of the air outlet 120 supports the guide plate 500. The airflow in the air duct 200 is guided so that the airflow blows along the air outlet gap 510 toward the air outlet 120. One side of the guide plate 500 is rotatably connected to the lower side of the air outlet 120. A lifting mechanism 520 is set between the guide plate 500 and the lower side of the air outlet 120. The lifting mechanism 520 is used to adjust the tilt angle of the guide plate 500, thereby changing the flow rate of the air outlet gap 510 to meet diverse air supply needs.

[0052] Optionally, the air outlet 120 has a rectangular opening structure, with a first side 123, a second side 124, a third side 125, and a fourth side 126. The first side 123 is the upper side of the air outlet 120, the second side 124 is the lower side, the third side 125 is the left side, and the fourth side 126 is the right side. All four sides protrude into the air duct 110 along a direction perpendicular to the plane of the air outlet 120. This arrangement facilitates the rotatable connection between one side of the guide plate 500 and the second side 124 of the air outlet 120, allowing the second side 124 to support the guide plate 500.

[0053] Specifically, the lower sides of both ends of the guide plate 500 along its length are rotatably connected to the second side 124 of the air outlet 120 via a bearing structure, and the lifting mechanism 520 is an electric push rod mechanism. Thus, because the guide plate 500 is inclined towards the air outlet 120, the lower sides of both ends of the guide plate are rotatably connected to the second side 124, making the guide plate 500 more stable. The electric push rod mechanism facilitates the adjustment of the tilt angle of the guide plate 500.

[0054] Specifically, the middle position of the second side 124 is adapted to the shape of the upper end of the air duct 200. In this way, since the upper end of the air duct 200 has an opening, the middle position of the second side 124 is adapted to the shape of the upper end of the air duct 200, thus avoiding the protruding second side 124 from obstructing the airflow within the air duct 200.

[0055] Combination Figure 7 and Figure 8 As shown, in some embodiments, the air duct 200 is provided with a plurality of evenly distributed guide protrusions 220, all of which are arranged along the flow direction of the air duct 110. In this way, by providing a plurality of guide protrusions 220, the airflow in the air duct 200 can be made to flow evenly, avoiding the accumulation of airflow in the air duct 200 and affecting the air ducting effect. The airflow in the air duct 200 is evenly guided to the second air outlet area 122 by the guide plate 500, thereby further improving the overall air outlet uniformity of the air outlet 120.

[0056] Optionally, the air conditioner unit also includes: longitudinal air guide plates 600. Multiple longitudinal air guide plates 600 are evenly arranged within the air outlet 120 to guide the airflow within the air outlet 120. The windward ends of some of the longitudinal air guide plates 600 are rotatably connected to multiple guide protrusions 220. In this way, the multiple evenly arranged longitudinal air guide plates 600 can guide the airflow blown out of the air outlet 120 horizontally, improving airflow diversity and meeting the user's airflow needs. Since the multiple guide protrusions 220 are arranged along the flow direction of the air duct 110, i.e., the guide protrusions 220 are arranged vertically, they can support the windward ends of some of the longitudinal air guide plates 600, making reasonable use of the air guiding structure within the air intake duct 200.

[0057] Optionally, multiple longitudinal air guide plates 600 are disposed between the first side 123 and the second side 124 of the air outlet 120. The upper ends of the multiple longitudinal air guide plates 600 are rotatably connected to the first side 123, the lower ends of some of the multiple longitudinal air guide plates 600 are rotatably connected to multiple guide protrusions 220, and the lower ends of the remaining longitudinal air guide plates 600 are rotatably connected to the second side 124. In this way, since the first side 123 is the upper edge of the air outlet 120 and the second side 124 is the lower edge of the air outlet 120, the multiple longitudinal air guide plates 600 are rotatably installed between the first side 123 and the second side 124, which facilitates the installation and rotation of the multiple longitudinal air guide plates 600 and improves the stability of air guidance. Moreover, the lower ends of some of the multiple longitudinal air guide plates 600 are supported by multiple guide protrusions 220, making reasonable use of the air guiding structure in the air duct 200.

[0058] Understandably, each guide protrusion 220 corresponds to the installation of a longitudinal air guide plate 600.

[0059] Optionally, each longitudinal air guide plate 600 has a linkage knob 610 at its lower end and a first connecting rod 620 on the windward side of the second side 124. Each linkage knob 610 is rotatably connected to the first connecting rod 620, and each linkage knob 610 can rotate relative to the first connecting rod 620. In this way, the first connecting rod 620 can synchronously drive multiple longitudinal air guide plates 600 to rotate simultaneously, thereby adjusting the wind direction in the horizontal direction. When one longitudinal air guide plate 600 rotates, the first connecting rod 620 can drive multiple longitudinal air guide plates 600 to rotate simultaneously.

[0060] Optionally, the lower end of the longitudinal air guide plate 600 closest to the third side 125 among the plurality of longitudinal air guide plates 600 is fixedly connected to the output end of the first drive motor 630. In this way, the first drive motor 630 drives the longitudinal air guide plate 600 closest to the third side 125 to rotate, thereby using the first connecting rod 620 to simultaneously drive the plurality of longitudinal air guide plates 600 to rotate.

[0061] Combination Figure 9 and Figure 10 As shown, in some embodiments, the air conditioner unit further includes a horizontal air guide plate 700. Multiple horizontal air guide plates 700 are provided, and these plates are evenly distributed inside the air outlet 120. In this way, multiple horizontal air guide plates 700 are used to guide the airflow in the air outlet 120 vertically, improving airflow diversity and meeting the user's airflow needs.

[0062] Optionally, one end of each of the multiple transverse air guide vanes 700 is rotatably connected to the third side 125 of the air outlet 120, and the other end of each of the multiple transverse air guide vanes 700 is rotatably connected to the fourth side 126 of the air outlet 120. Thus, the third side 125 and the fourth side 126 are opposite edges in the horizontal direction of the air outlet 120. Therefore, rotatably installing the multiple transverse air guide vanes 700 between the third side 125 and the fourth side 126 facilitates the installation and rotation of the multiple transverse air guide vanes 700 and improves the rotational stability of the multiple transverse air guide vanes 700.

[0063] Optionally, the other ends of the multiple transverse air guides 700 are all disposed through the fourth side 126. A second connecting rod 710 is provided on the side wall of the fourth side 126 facing away from the air outlet 120. The other end of each transverse air guide 700 is provided with a crank 720. The crank 720 at the other end of each transverse air guide 700 is rotatably connected to the second connecting rod 710 and can rotate relative to the second connecting rod 710. In this way, the up and down movement of the second connecting rod 710 drives the crank 720 to rotate, thereby simultaneously driving the multiple transverse air guides 700 to rotate, thereby adjusting the airflow at the air outlet 120 in the vertical direction.

[0064] Optionally, a second drive motor 730 is provided at the lower end of the second connecting rod 710. The second drive motor 730 is also connected to the lower end of the second connecting rod 710 via a crank 720. One end of the crank 720 is fixedly connected to the output end of the second drive motor 730, and the other end is rotatably connected to the lower end of the second connecting rod 710. In this way, the second drive motor 730 drives the crank 720 to rotate, thereby driving the second connecting rod 710 to move up and down.

[0065] Combination Figure 11As shown, in some embodiments, the air conditioner unit further includes an air outlet insulation frame 800. The air outlet insulation frame 800 is embedded in the inner wall of the air duct 110 corresponding to the edge of the air outlet 120. In this way, by setting the air outlet insulation frame 800, the air outlet 120 is sealed and insulated, reducing the heat exchange between the cold airflow in the air duct 110 and the casing 100, reducing the leakage of cold air, and reducing the risk of condensation on the outer surface of the casing 100.

[0066] Optionally, the outer edge of the air outlet 120 is provided with an embedding groove 130 surrounding the air outlet 120, and the air outlet insulation frame 800 is embedded in the embedding groove 130. In this way, embedding the air outlet insulation frame 800 in the embedding groove 130 can improve the installation stability of the air outlet insulation frame 800 and improve the insulation and sealing effect of the air outlet insulation frame 800.

[0067] Specifically, the outer sides of the first side 123, the second side 124, the third side 125 and the fourth side 126 of the air outlet 120 are provided with embedded grooves 130 surrounding the air outlet 120.

[0068] Optionally, the air duct 200 is a groove-shaped structure formed inside the air outlet insulation frame 800. In this way, the air duct 200 is defined by the structure of the air outlet insulation frame 800 itself. While the air outlet insulation frame 800 is used to seal and insulate the outer edge of the air outlet 120, the structure of the air outlet insulation frame 800 is reasonably utilized to set the air duct 200 on its inner side, so as to guide part of the airflow in the air duct 110 to the second air outlet area 122 of the air outlet 120 and blow it out, thereby improving the overall air outlet uniformity of the air outlet 120.

[0069] Specifically, the air duct 200 is formed in a portion of the air outlet insulation frame 800 corresponding to the second side 124 of the air outlet 120. In this way, the airflow from bottom to top in the air duct 110 is guided by the air duct 200 to the second air outlet area 122 and blown out when it flows through the second side 124 of the air outlet 120.

[0070] Optionally, an airflow lifting surface 810 is provided on the portion of the air outlet insulation frame 800 corresponding to the windward side of the air outlet 120. In this way, since the air outlet insulation frame 800 is embedded on the outer edge of the air outlet 120, in order to reduce the obstruction of the airflow in the air duct 110 by the air outlet insulation frame 800, an airflow lifting surface 810 is provided on the portion of the air outlet insulation frame 800 corresponding to the windward side of the air outlet 120. This allows the airflow flowing from bottom to top to flow along the air outlet insulation frame 800 to the vicinity of the air outlet 120 under the action of the airflow lifting surface 810, thereby reducing the loss of airflow pressure in the air duct 110.

[0071] Specifically, the part of the air outlet insulation frame 800 corresponding to the second side 124 of the air outlet 120 is provided with an airflow lifting surface 810.

[0072] Combination Figure 12 and Figure 13 As shown, in some embodiments, the air outlet insulation frame 800 includes: a first part 820, a second part 830, a third part 840, and a fourth part 850. The first part 820 is embedded on the upper side of the first side 123; the second part 830 is embedded on the lower side of the second side 124; the third part 840 is embedded on the left side of the third side 125 and wraps around one end of the first side 123 and the second side 124; the fourth part 850 is embedded on the right side of the fourth side 126 and wraps around the other end of the first side 123 and the second side 124; wherein, the first part 820, the second part 830, the third part 840, and the fourth part 850 are sequentially connected end to end to form the air outlet insulation frame 800. In this way, the first part 820 is embedded on the upper side of the first side 123 of the air outlet 120, the second part 830 is embedded on the lower side of the second side 124 of the air outlet 120, the third part 840 is embedded on the left side of the third side 125, and the fourth part 850 is embedded on the right side of the fourth side 126. Thus, the air outlet insulation frame 800 forms a surrounding seal and insulation around the air outlet 120, further reducing the leakage of cold air. Moreover, while the third part 840 surrounds the third side 125, it also encloses the first side 123 and the second side 124. At the end, the fourth part 850 surrounds the fourth side 126, and at the same time, it can also wrap the other end of the first side 123 and the second side 124, so as to prevent the leakage of cold air in the corners where the first side 123 connects to the third side 125, the corners where the second side 124 connects to the third side 125, the corners where the first side 123 connects to the fourth side 126, and the corners where the second side 124 connects to the fourth side 126. This improves the sealing of the corner areas where adjacent edges are connected, and even if the insulation frame shrinks, it can still provide good sealing and insulation for the corner areas of the air outlet 120.

[0073] Specifically, the airflow lifting surface 810 is located at the windward end of the third part 840 and the fourth part 850.

[0074] Optionally, the first part 820 is provided with a first protrusion 821 at one end opposite to the third part 840, and the third part 840 is provided with a first groove 841 adapted to the first protrusion 821 at one end opposite to the first part 820; the first part 820 is provided with a second protrusion 822 at one end opposite to the fourth part 850, and the fourth part 850 is provided with a second groove 851 adapted to the second protrusion 822 at one end opposite to the first part 820; the first protrusion 821 is engaged in the first groove 841, and the second protrusion 822 is engaged in the second groove 851, so that the two ends of the first part 820 are respectively engaged and connected with the third part 840 and the fourth part 850. In this way, the two ends of the first part 820 are respectively engaged with the first groove 841 and the second groove 851 at the ends of the third part 840 and the fourth part 850 through the first boss 821 and the second boss 822. Since the first boss 821 is engaged in the first groove 841 and the second boss 822 is engaged in the second groove 851, a stepped sealing method is formed at the connection between the first part 820 and the third part 840 and the connection between the first part 820 and the fourth part 850. Even if the first part 820, the third part 840 and the fourth part 850 shrink and deform, they can still form a good blocking effect on the airflow, reduce the leakage of cold energy, and reduce the risk of condensation on the shell 100.

[0075] Optionally, the third part 840 is provided with a third protrusion 842 at one end opposite to the second part 830, and the second part 830 is provided with a third groove 831 adapted to the third protrusion 842 at one end opposite to the third part 840, and the third groove 831 is a groove-shaped structure extending downward along the inner side of the end of the second part 830; the fourth part 850 is provided with a fourth protrusion 852 at one end opposite to the second part 830, and the second part 830 is provided with a fourth groove 832 adapted to the fourth protrusion 852 at one end opposite to the fourth part 850, and the fourth groove 832 is also a groove-shaped structure extending downward along the inner side of the end of the second part 830; the third protrusion 842 is engaged in the third groove 831, and the fourth protrusion 852 is engaged in the fourth groove 832, so that the two ends of the second part 830 are respectively engaged and connected with the third part 840 and the fourth part 850. In this way, the two ends of the second part 830 are respectively engaged with the third groove 831 and the fourth groove 832 at the ends of the third part 840 and the fourth part 850 via the third boss 842 and the fourth boss 852. Since the second part 830 is located below the second side 124 of the air outlet 120, and the second side 124 is the lower edge of the air outlet 120, the second part 830 is located below the air outlet 120. The third groove 831 and the fourth groove 832 are both set as groove-shaped structures extending downward along the inner side of the end of the second part 830. The fourth boss 852 at the end of the third boss 842 and the fourth boss 850 can support the second part 830. Even if the second part 830 shrinks and deforms, it can still be firmly connected with the third part 840 and the fourth part 850, preventing the second part 830 from coming out of the embedded groove 130 under the action of gravity. Moreover, by using the snap-fit ​​method of the boss and the groove, a stepped seal is formed at the connection between the second part 830 and the third part 840, and at the connection between the second part 830 and the fourth part 850, blocking the leakage of cold air, reducing the leakage of cold energy, and reducing the risk of condensation on the air outlet panel.

[0076] Specifically, along the direction perpendicular to the plane where the air outlet 120 is located, the thickness of the second part 830 is less than the thickness of the third part 840 and the fourth part 850. After the two ends of the second part 830 are respectively engaged with the third part 840 and the fourth part 850, an air duct 200 is formed between the windward side of the second part 830, the end face of the third part 840 and the end face of the fourth part 850.

[0077] Combination Figure 14As shown, in some embodiments, a first receiving groove 843 is provided at the leeward side of the lower end of the third part 840 of the air outlet heat preservation frame 800, and a first drive motor 630 is installed in the first receiving groove 843; a second receiving groove 853 is provided at the leeward side of the lower end of the fourth part 850, and a second drive motor 730 is installed in the second receiving groove 853. In this way, the third part 840 and the fourth part 850 of the air outlet insulation frame 800 are used to accommodate the first drive motor 630 and the second drive motor 730. Moreover, since the first accommodating groove 843 and the second accommodating groove 853 are respectively located on the leeward side of the third part 840 and the fourth part 850, that is, on the side of the third part 840 and the fourth part 850 facing the housing 100, the third part 843 and the fourth part 850 can isolate the cold airflow in the air duct 110 from contact with the first drive motor 630 and the second drive motor 730, avoid condensation on the outer surface of the first drive motor 630 and the second drive motor 730, and reduce the loss of cold air in the air duct 110.

[0078] Optionally, the output shaft of the first drive motor 630 passes through the second side 124 and is fixedly connected to the lower end of the longitudinal air guide plate 600 near the third side 125 among the multiple longitudinal air guide plates 600. In this way, since the lower end of the third part 840 wraps around the end of the second side 124, the first drive motor 630 is placed in the first receiving groove 843, which facilitates the connection between the first drive motor 630 and the lower end of the longitudinal air guide plate 600. The lower end of the longitudinal air guide plate 600 near the third side 125 is fixedly connected to the output shaft of the first drive motor 630. The first drive motor 630 drives the longitudinal air guide plate 600 to rotate, and under the action of the first connecting rod 620, it simultaneously drives the multiple longitudinal air guide plates 600 to rotate, thereby guiding the airflow of the air outlet frame in the horizontal direction.
