Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a vertical air-conditioning indoor unit and an air duct component thereof. Background Art

[0002] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners consist of an indoor heat exchanger, an outdoor heat exchanger, a compressor, a throttling device, and other necessary components including a dryer and a four-way valve to form a vapor compression refrigeration cycle system, which outputs cold / hot air through a cross-flow fan to achieve cooling and heating of the indoor environment.

[0003] The vertical air conditioner indoor unit is a common indoor unit of air conditioners. When the air conditioner is in cooling operation, the temperature of the fan, heat exchanger and other components of the vertical air conditioner indoor unit is low, and the surrounding air condenses on the surface of the components to produce condensed water. If the condensed water is not properly guided, it may be blown into the indoor environment with the air flow, forming a blown water.

[0004] In the vertical air conditioner indoor unit, the evaporator is close to the rear side of the housing and is arranged opposite to the air duct component, and the electrical box is arranged at one end of the air duct component. The air duct component is mainly defined by the volute and the volute tongue, the cross-flow fan is rotatably arranged inside the air duct, and the motor is arranged at the other end of the air duct component to drive the cross-flow fan. The wires for connecting the motor and the electrical box need to be wired.

[0005] During the cooling process of the air conditioner, condensation water will be generated on the wires. If the wires are not sorted out, the condensation water may slide along the wires and out of the water tray, causing the condensation water to drip onto other parts inside the air conditioner, causing potential malfunctions, or the condensation water may drip onto the floor of the user's home, affecting the user experience. Utility Model Content

[0006] The purpose of the utility model is to provide a vertical air-conditioning indoor unit which overcomes the above problems or at least partially solves the above problems.

[0012] The first upper backwater bend buckle is arranged on the outer surface and is positioned higher than the first lower backwater bend buckle, so as to allow the wire to pass through the multiple first routing buckles, the first lower backwater bend buckle and the first upper backwater bend buckle in sequence from top to bottom, and then extend downward to form a downwardly convex lower backwater bend at the first lower backwater bend buckle, and to form an upwardly convex upper backwater bend at the first upper backwater bend buckle.

[0019] Optionally, the air duct component includes a top cover located at the top of the volute and a water receiving tray located at the bottom of the volute;

[0020] The plurality of first wiring buckles, the first lower water return bend buckle and the first upper water return bend buckle are all located directly above the water receiving tray, so that the wires constrained by them can drip toward the water receiving tray.

[0022] A plurality of second wiring buckles arranged in a vertical direction on the outer surface of the volute;

[0023] A second lower water return bend buckle, which is disposed on the outer surface and is located lower than the second wiring buckle at the lowermost side; and

[0024] The second upper backwater bend buckle is arranged on the outer surface and is positioned higher than the second lower backwater bend buckle, so as to allow the wire to pass through the multiple second routing buckles, the second lower backwater bend buckle and the second upper backwater bend buckle in sequence from top to bottom, and then extend downward to form a downwardly convex lower backwater bend at the second lower backwater bend buckle, and to form an upwardly convex upper backwater bend at the second upper backwater bend buckle.

[0025] Optionally, each of the second wiring buckles is arranged side by side with one of the first wiring buckles;

[0026] Each of the second lower water return bend buckles is arranged side by side with one of the first lower water return bend buckles; and

[0030] In this way, the condensed water sliding down the wire cannot continue to slide along the wire at the lower return water bend and the upper return water bend.

This buckle layout makes the bending degree of the upper and lower water return bends of the wire more reasonable, avoiding damage due to excessive bending angles.

[0032] Furthermore, in the vertical air conditioner indoor unit and the air duct component thereof of the utility model, a second wiring buckle, a second lower water return bend buckle and a second upper water return bend buckle are correspondingly provided. In this way, the weak current wire is fixed by the first wiring buckle, the first lower water return bend buckle and the first upper water return bend buckle, and the strong current wire is fixed by the second wiring buckle, the second lower water return bend buckle and the second upper water return bend buckle, so as to realize the separation of strong current and weak current.

Specifically, it regulates the temperature, humidity, and air quality of the air, humidifies and dehumidifies the indoor air, introduces fresh air, etc. The air conditioner can form a vapor compression refrigeration cycle system consisting of an evaporator, a condenser, a compressor, a throttling device, and other necessary components to output cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0050] Figure 1 It is a structural schematic diagram of a vertical air-conditioning indoor unit according to an embodiment of the utility model; Figure 2 It is a partial structural schematic diagram of an air duct component 60 for a vertical air conditioner indoor unit according to an embodiment of the utility model; Figure 3 yes Figure 2 A schematic diagram of the wiring path of the air duct component 60 is shown.

[0051] like Figures 1 to 3 As shown, the air duct component 60 for a vertical air conditioner indoor unit of the embodiment of the utility model may generally include a volute 62 , a plurality of first wiring buckles 110 , 120 , 130 , 140 , a first lower water return bend buckle 150 and a first upper water return bend buckle 160 .

[0052] The volute 62 has an inner surface 621 and an outer surface 622. The inner surface 621 is used to define a crossflow air duct. The volute 62 extends vertically as a whole to be suitable for a vertical air conditioner indoor unit. A crossflow fan is arranged inside the crossflow air duct, and the axis of the crossflow fan extends vertically.

[0053] In addition, the air duct component 60 may further include a top cover 61 located at the top of the volute 62 and a water receiving tray 63 located at the bottom of the volute 62. The top cover 61 is fixedly connected to the top edge of the volute 62, and the water receiving tray 63 is fixedly connected to the bottom edge of the volute 62. The upper and lower ends of the crossflow fan are rotatably mounted on the top cover 61 and the water receiving tray 63, respectively. The crossflow fan includes a motor, which may be mounted on the upper side of the top cover 61.

[0054] A plurality of first routing buckles 110 , 120 , 130 , 140 are arranged in a vertical direction on the outer surface 622 of the volute 62 to constrain the wires abutting against the outer surface 622 of the volute 62 .

[0055] The first lower water return bend buckle 150 is disposed on the outer surface 622 and is located lower than the lowermost first wiring buckles 110, 120, 130, 140, 140. That is, the first lower water return bend buckle 150 is located lower than all the first wiring buckles 110, 120, 130, 140.

[0056] The first upper backwater bend buckle 160 is disposed on the outer surface 622 and is located higher than the first lower backwater bend buckle 150, so as to allow the wire to pass through the first routing buckles 110, 120, 130, 140, the first lower backwater bend buckle 150 and the first upper backwater bend buckle 160 from top to bottom in sequence, and then extend downward to form a downwardly convex lower backwater bend at the first lower backwater bend buckle 150 and an upwardly convex upper backwater bend at the first upper backwater bend buckle 160, as shown in FIG. Figure 3 .

[0057] In the vertical air conditioner indoor unit and the air duct component 60 of the embodiment of the utility model, not only a plurality of conventional first wiring buckles 110, 120, 130, 140 are provided, but also a first lower water return bend buckle 150 and a first upper water return bend buckle 160 are provided. The first lower water return bend buckle 150 is provided on the outer surface 622 and is located lower than the first wiring buckles 110, 120, 130, 140140 at the lowermost side. The first upper backwater bend buckle 160 is arranged on the outer surface 622 and is positioned higher than the first lower backwater bend buckle 150, so as to allow the wire to pass through multiple first routing buckles 110, 120, 130, 140, the first lower backwater bend buckle 150 and the first upper backwater bend buckle 160 from top to bottom in sequence, and then extend downward to form a downwardly convex lower backwater bend at the first lower backwater bend buckle 150, and an upwardly convex upper backwater bend at the first upper backwater bend buckle 160.

[0058] In this way, the condensed water sliding down the wire cannot continue to slide along the wire at the lower water return bend and the upper water return bend. Under the action of gravity, the accumulated water will eventually drip onto the water receiving tray 63, avoiding dripping onto other components and causing potential malfunctions.

[0059] In some embodiments of the present invention, Figure 3 As shown, the first lower water return bend buckle 150 and the first routing buckles 110, 120, 130, 140, 140 at the bottom are staggered in the horizontal width direction (positive and negative directions of the x-axis) of the outer surface 622, that is, the coordinates of the two on the x-axis are different. Figure 3 As shown, the first lower water return bend buckle 150 is further to the right on the paper.

[0060] Furthermore, in the horizontal width direction (positive and negative directions of the x-axis) of the outer surface 622, the bottommost 140 can be located between the first lower water return bend buckle 150 and the first upper water return bend buckle 160. That is, the coordinates of the three on the x-axis are different. Specifically, Figure 3 As shown, the first lower water return bend buckle 150 is located further to the right on the paper, and the first upper water return bend buckle 160 is located further to the left.

[0061] In the vertical air-conditioning indoor unit and the air duct component 60 thereof of the embodiment of the utility model, the first lower water return bend buckle 150 and the first wiring buckle 140 at the lowest side are staggered with each other in the horizontal width direction of the outer surface 622. Furthermore, in the horizontal width direction of the outer surface 622, the first wiring buckle 140 at the lowest side is located between the first lower water return bend buckle 150 and the first upper water return bend buckle 160. This buckle layout makes the bending degree of the upper and lower water return bends of the conductor more reasonable, avoiding damage caused by excessive bending angles.

[0062] Assuming that the first routing buckle 140, the first lower backwater bend buckle 150 and the first upper backwater bend buckle 160 at the bottom are collinear in the vertical direction, the wire extends downward from the first routing buckle 140, bends upward after passing through the first lower backwater bend buckle 150, and then bends downward after passing through the first upper backwater bend buckle 160, and three segments of wires will be superimposed, and the bending angle of the wire is close to 180°. If the bending angle is too large, the wire is prone to fatigue damage if it is in this state for a long time. The embodiment of the utility model solves this problem by reasonably arranging the positions of the first routing buckle 140, the first lower backwater bend buckle 150 and the first upper backwater bend buckle 160 at the bottom.

[0063] In some embodiments of the present invention, Figure 3 As shown, a plurality of first routing buckles 110, 120, 130, 140 are arranged in a straight line in the vertical direction. Such a design enables the wire to extend in a straight line in this section without the need for bending operations.

[0064] Figure 4 yes Figure 2 Another schematic view of the air duct component 60 is shown.

[0065] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air duct component 60 further includes a first outlet buckle 170, which is located lower than the first upper water return bend buckle 160, so as to constrain the wires led downward from the first upper water return bend buckle 160. In this way, the first outlet buckle 170 is used to constrain the wires bent downward from the first upper water return bend buckle 160, so that the upper water return bend remains in a bent state.

[0066] Furthermore, in some embodiments, Figure 4 As shown, the air duct component 60 includes a top cover 61 located at the top of the volute 62 and a water receiving tray 63 located at the bottom of the volute 62 , and the first outlet buckle 170 is formed on the outer wall of the water receiving tray 63 .

[0067] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air duct component 60 includes a top cover 61 located at the top of the volute 62 and a water receiving pan 63 located at the bottom of the volute 62. A plurality of first wiring buckles 110, 120, 130, 140, a first lower water return bend buckle 150 and a first upper water return bend buckle 160 are all located directly above the water receiving pan 63, so that the wires constrained by them drip water toward the water receiving pan 63.

[0068] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air duct component 60 may further include a plurality of second wiring buckles 210 , 220 , 230 , 240 , a second lower water return bend buckle 250 and a second upper water return bend buckle 260 .

[0069] In this way, the first routing buckles 110, 120, 130, 140, the first lower backwater bend buckle 150 and the first upper backwater bend buckle 160 are used to fix the weak current wires, and the second routing buckles 210, 220, 230, 240, the second lower backwater bend buckle 250 and the second upper backwater bend buckle 260 are used to fix the strong current wires, thereby achieving the separation of strong current and weak current.

[0070] A plurality of second routing buckles 210, 220, 230, 240 are arranged in a vertical direction on the outer surface 622 of the volute 62. A second lower backwater bend buckle 250 is arranged on the outer surface 622 and is located lower than the second routing buckle 240 at the lowermost side. A second upper backwater bend buckle 260 is arranged on the outer surface 622 and is located higher than the second lower backwater bend buckle 250, so as to allow the wire to pass through the plurality of second routing buckles 210, 220, 230, 240, the second lower backwater bend buckle 250 and the second upper backwater bend buckle 260 in sequence from top to bottom, and then extend downward, so as to form a downward convex lower backwater bend at the second lower backwater bend buckle 250, and form an upward convex upper backwater bend at the second upper backwater bend buckle 260. In this way, the condensed water sliding down the wire cannot continue to slide along the wire at the lower water return bend and the upper water return bend. Under the action of gravity, the accumulated water will eventually drip onto the water receiving tray 63, avoiding dripping onto other components and causing potential malfunctions.

[0071] In some embodiments of the present invention, Figure 3As shown, the second lower water return bend buckle 250 and the second routing buckle 240 at the bottom are staggered in the horizontal width direction (positive and negative directions of the x-axis) of the outer surface 622, that is, the coordinates of the two on the x-axis are different. Figure 3 As shown, the second lower water return bend buckle 250 is further to the right on the paper.

[0072] Furthermore, in the horizontal width direction (positive and negative directions of the x-axis) of the outer surface 622, the second routing buckle 240 at the bottom can be located between the second lower water return bend buckle 250 and the second upper water return bend buckle 260. That is, the coordinates of the three on the x-axis are different. Specifically, Figure 3 As shown, the second lower water return bend buckle 250 is located further to the right on the paper, and the second upper water return bend buckle 260 is located further to the left.

[0073] In the vertical air-conditioning indoor unit and the air duct component 60 thereof of the embodiment of the utility model, the second lower water return bend buckle 250 and the second wiring buckle 240 at the lowest side are staggered with each other in the horizontal width direction of the outer surface 622. Furthermore, in the horizontal width direction of the outer surface 622, the second wiring buckle 240 at the lowest side is located between the second lower water return bend buckle 250 and the second upper water return bend buckle 260. This buckle layout makes the bending degree of the upper and lower water return bends of the conductor more reasonable, avoiding damage due to excessive bending angles.

[0074] Assuming that the second wiring buckle 240, the second lower backwater bend buckle 250 and the second upper backwater bend buckle 260 at the bottom are collinear in the vertical direction, the wire extends downward from the second wiring buckle 240, bends upward after passing through the second lower backwater bend buckle 250, and then bends downward after passing through the second upper backwater bend buckle 260, and three segments of wires will be superimposed, and the bending angle of the wire is close to 180°. If the bending angle is too large, the wire is prone to fatigue damage if it is in this state for a long time. The embodiment of the utility model solves this problem by reasonably arranging the positions of the second wiring buckle 240, the second lower backwater bend buckle 250 and the second upper backwater bend buckle 260 at the bottom.

[0075] In some embodiments of the present invention, Figure 3 As shown, a plurality of second wiring buckles 210, 220, 230, 240 are arranged in a straight line in the vertical direction. Such a design enables the wire to extend in a straight line in this section without the need for bending operations.

[0076] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the air duct component 60 also includes a second outlet buckle 270 , and the position of the second outlet buckle 270 is lower than the second upper water return buckle 260 , so as to constrain the wires led downward from the second upper water return buckle 260 .

[0077] In this way, the second outlet buckle 270 is used to constrain the wire bent downward from the second upper water return bend buckle 260, so that the upper water return bend remains in a bent state.

[0078] Furthermore, in some embodiments, Figure 4 As shown, the air duct component 60 includes a top cover 61 located at the top of the volute 62 and a water receiving tray 63 located at the bottom of the volute 62 , and the second outlet buckle 270 is formed on the outer wall of the water receiving tray 63 .

[0079] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, multiple second wiring buckles 210 , 220 , 230 , 240 , second lower water return bend buckle 250 and second upper water return bend buckle 260 are all located directly above the water receiving tray 63 , so that the wires constrained by them can drip toward the water receiving tray 63 .

[0080] In some embodiments of the utility model, each second wiring buckle 210, 220, 230, 240 is arranged side by side with a first wiring buckle 110, 120, 130, 140, each second lower backwater bend buckle 250 is arranged side by side with a first lower backwater bend buckle 150, and each second upper backwater bend buckle 260 is arranged side by side with a first upper backwater bend buckle 160. Such an arrangement can make the buckles arranged more neatly. In addition, one of the two buckles arranged side by side can be used to block the opening of the other buckle, making the overall structure simpler. Figure 5 As shown, the second routing buckles 210 , 220 , 230 , 240 block the openings on the left side of the first routing buckles 110 , 120 , 130 , 140 .

[0081] Figure 5 yes Figure 4 Enlarged view of point A.

[0082] Below through Figure 5 The buckle structure of the embodiment of the utility model is introduced. Figure 5 The structure of the first wiring buckle 110 and the second wiring buckle 210 in parallel is described. However, the other first wiring buckles 120, 130, 140 and the other second wiring buckles 220, 230, 240, the first lower backwater bend buckle 150, the second lower backwater bend buckle 250, and the second upper backwater bend buckle 260, the second upper backwater bend buckle 260 may also adopt the same or similar structure.

[0084] The first wiring buckle 110 includes a first root portion 111 extending outward from the outer surface 622 of the volute 62, a first main body portion 112 bent from the end of the first root portion 111 toward the second wiring buckle 210, and a first hook 113 bent from the end of the first main body portion 112 toward the outer surface 622 of the volute 62.

[0085] The second wiring buckle 210 includes a second root portion 211 extending outward from the outer surface 622 of the volute 62, and the second root portion 211 is adjacent to the first hook 113 and has a gap to allow the wire to pass through the gap and enter the inside of the first main body portion 112. The second wiring buckle 210 also includes a second main body portion 212 extending from the end of the second root portion 211 in a direction away from the first wiring buckle 110 and a second hook 213 bent from the end of the second main body portion 212 toward the outer surface 622 of the volute 62. In addition, the second wiring buckle 210 also includes a blocking portion 215 extending outward from the outer surface 622 of the volute 62, and the blocking portion 215 and the second hook 213 have a gap to allow the wire to pass through.

[0086] The embodiment of the utility model further provides a vertical air-conditioning indoor unit, which includes an air duct component 60 as in any of the above embodiments.

[0087] Specifically, Figure 1 As shown, the vertical air conditioner indoor unit may include a casing 10, an air duct component 60, and a cross-flow fan.

[0088] The heat exchanger, the throttling device, the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the outdoor unit of the air conditioner are connected through pipelines to form a vapor compression refrigeration cycle system. The compressor is usually a rolling rotor compressor. The throttling device may include a capillary tube and an electronic expansion valve. For a heat pump air conditioner, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between a cooling mode and a heating mode. For a heat pump air conditioner, in the cooling mode, the heat exchanger plays the role of an evaporator. In the heating mode, the heat exchanger plays the role of a condenser.

[0089] The housing 10 is provided with an air inlet (not shown) and an air outlet 12. Under the action of the cross-flow fan, indoor air enters the housing 10 through the air inlet, and after completing heat exchange with the heat exchanger, forms a heat exchange airflow. Under the guidance of the cross-flow air duct, the heat exchange airflow flows out through the air outlet 12. Specifically, when the air conditioner is in cooling mode, the heat exchange airflow is a cold airflow. When the air conditioner is in heating mode, the heat exchange airflow is a hot airflow.
