[0002] At present, the upper and lower air cabinet can achieve carpet-style heating and shower-style cooling, which is comfortable and has great development prospects. When the upper and lower air cabinet is cooling, the normal temperature air will become cold air after passing through the evaporator, so that there is a temperature difference between the inside and outside of the volute and the volute cover of the air duct, and condensation water is very easy to form on the surface of the volute and the volute cover. The air duct components and the air inlet panel components in the prior art are generally designed to be assembled vertically.

[0003] However, due to the problem of volute demolding, the water receiving surface of the water receiving structure on the volute is demolded toward the outside, causing the condensed water left on the volute water receiving surface to easily flow outward instead of toward the water receiving pan, posing a major safety hazard.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figures 1 to 6 As shown, the first embodiment of the present invention provides an air duct installation structure, which includes an air duct structure 10, a water receiving tray 20 and an installation panel 30. The water receiving tray 20 is installed on the air duct structure 10. The air duct structure 10 is provided with a water diversion groove 11 that is connected to the water receiving tray 20. The water diversion groove 11 has a first connecting port 111 and a second connecting port 112 that are arranged oppositely. The first connecting port 111 is located on a side of the second connecting port 112 close to the water receiving tray 20. Along the extension direction from the second connecting port 112 to the first connecting port 111, the height of the groove bottom of the water diversion groove 11 gradually decreases. The air duct structure 10 is installed on the side of the installation panel 30. The air duct structure 10 is inclined at a preset angle relative to the installation panel 30, so that the height of the first connecting port 111 is reduced and the height of the second connecting port 112 is increased. Specifically, the height difference between the first connecting port 111 and the second connecting port 112 of the water diversion groove 11 is caused when demolding.

[0027] With such a structural setting, the height of the first communication port is reduced and the height of the second communication port is increased by installing the device at a preset angle, so that the water in the water diversion groove 11 can flow out in the direction of the first communication port better, so that the water can flow smoothly into the water receiving pan 20 through the first communication port, thereby reducing the outflow of condensed water. Therefore, the technical solution provided by this embodiment can solve the technical problem in the prior art that the condensed water on the air duct structure 10 cannot smoothly enter the water receiving pan 20.

[0028] Specifically, the preset angle in this embodiment is α, and the angle between the extension direction from the first communication port to the second communication port and the horizontal direction is β, α>β. With such a structural arrangement, the height of the first communication port can be lower than the height of the second communication port, so that the water in the water diversion groove 11 can smoothly flow from the second communication port to the first communication port, and smoothly flow into the water receiving tray 20.

[0029] In this embodiment, the mounting panel 30 has an assembly plane 31, and the assembly plane 31 is set at a preset angle with the vertical plane, so that the air duct structure 10 is installed on the assembly plane 31 at a preset angle. With such a structural setting, during installation, it is only necessary to directly assemble the air duct structure 10 with the assembly plane 31, which is simple to operate and convenient for assembly.

[0030] Specifically, the air duct structure 10 in this embodiment includes a volute 12 and a volute cover 13, and the water diversion groove 11 is arranged on the volute 12. The volute cover 13 is installed on the volute 12, and a water diversion hole 14 connected with the water diversion groove 11 is arranged on the volute cover 13. The water receiving pan 20 is installed on the side of the volute cover 13 away from the volute 12, and the water diversion hole 14 is connected with the water receiving pan 20, so that the water in the water diversion groove 11 enters the water receiving pan 20 through the water diversion hole 14. With such a structural arrangement, it is convenient for the water on the volute 12 and the volute cover 13 to enter the water receiving pan 20 smoothly.

[0031] In this embodiment, a first water receiving strip 15 is further provided on the side of the volute cover 13 away from the volute 12. The first water receiving strip 15 protrudes from the side wall of the volute cover 13. The first water receiving strip 15 is located between the water inlet hole 14 and the water receiving tray 20 to facilitate the liquid flowing out of the water inlet hole 14 to enter the water receiving tray 20 through the first water receiving strip 15.

[0032] Specifically, at least a portion of the first water receiving bar 15 is tilted relative to the vertical direction, so that the water on the first water receiving bar 15 can flow smoothly into the water receiving tray 20 .

[0033] In this embodiment, a second water receiving bar 16 is provided on the side of the volute 12 away from the volute cover 13. The second water receiving bar 16 protrudes from the side wall of the volute 12. At least a portion of the second water receiving bar 16 is located above the water diversion groove 11 to facilitate the water on the second water receiving bar 16 to flow into the water diversion groove 11 and then enter the water receiving tray 20.

[0034] Specifically, the mounting panel 30 in this embodiment is an air inlet panel, on which an air inlet portion 32 is disposed, and the air duct structure 10 is disposed opposite to the air inlet portion 32. With such a structural arrangement, it is convenient to allow air to enter the air duct structure 10 through the air inlet panel.

[0035] In this embodiment, an evaporator assembly is provided between the air duct structure 10 and the air inlet 32, and a water receiving tray 20 is provided on one side of the air duct structure 10 close to the air inlet 32 ​​and at the bottom of the evaporator assembly to receive condensed water on the evaporator assembly. The above structure is compact, optimizes the structural layout, and is also convenient for collecting condensed water in the air duct installation structure.

[0036] The present invention solves the following technical problems: due to the demoulding problem of the volute 12, the water receiving surface of the water receiving structure below the volute 12 is tilted outward, causing condensed water to flow outward, which easily causes condensed water to drip to the bottom, causing great safety hazards and affecting the reliability of the whole machine. The water receiving surface of the water receiving structure of the volute cover 13 has a small tilt angle, which makes it difficult for the water in the volute cover 13 to be discharged to the water receiving tray 20.

[0037] The present invention is designed to be assembled at a certain angle between the air duct component and the air inlet panel, and the angle of inclination α is greater than the draft angle β of the water receiving surface of the water receiving structure of the volute 12, which can effectively prevent the outward inclination of the drainage surface of the water diversion structure of the volute 12 of the air duct component, causing the condensed water generated in the volute 12 to flow outward, and ensure that the condensed water of the volute 12 flows to the water receiving structure of the volute cover 13, and at the same time, the angle of the water receiving surface of the water receiving structure of the volute cover 13 can be increased, so that the condensed water on the volute cover 13 is easier to flow to the water receiving tray 20. This structure effectively ensures that the condensed water of the air duct flows to the water receiving tray 20, and ensures the safety and reliability of the whole machine.

[0038] The air duct components and air inlet panels of existing upper and lower air outlet cabinets are generally assembled vertically. A water collecting structure is generally designed under the volute 12 and the volute cover 13 of the air duct components to receive the condensed water generated on the volute 12 and the volute cover 13. Since the water collecting surface of the water collecting structure of the volute 12 is demolded outward, the maximum demolding angle of the volute 12 is β, which causes the condensed water generated on the volute 12 to flow outward easily and drip under the cabinet, where there are electrical box components, etc., which may easily cause greater safety hazards and reduce the reliability of the entire machine.

[0039] The present invention provides a water diversion structure for the inclined assembly of air duct components, and the surface where the air inlet panel and the air duct component are assembled is designed to be inclined at an angle α. The assembly surface of the air duct component is a vertical surface, and after being assembled with the inclined assembly surface of the air inlet panel, the air duct component as a whole is in a state of inclination angle α. Since the air inlet panel is inclined backward at an angle α, the air duct component is also synchronously inclined backward at an angle α after assembly. The water receiving surface of the volute 12 of the air duct component is prone to cause condensed water to flow outward due to the demolding angle β (also known as the demolding angle β). However, when the air duct inclination angle α is greater than the maximum demolding angle β of the water receiving surface of the volute 12 of the air duct component, the water receiving surface of the volute 12 is always in a state of inclination toward the inside of the water receiving tray 20, rather than inclination toward the outside, ensuring that the water received by the volute 12 flows toward the water receiving tray 20, rather than outward. The condensed water of the volute 12 is discharged to the water receiving structure of the volute cover 13 through the drain port, and finally discharged to the water receiving tray 20. This structure prevents condensed water from dripping under the air conditioner cabinet, thereby improving the safety and reliability of the entire machine.

[0040] At the same time, since the air duct component is tilted backward at an angle α, the tilt angle of the water receiving surface of the volute cover 13 of the air duct component also increases at an angle α, making it easier for the condensed water of the volute cover 13 to flow to the water receiving tray 20, improving the water diversion and water receiving efficiency, and making the whole machine more reliable. The water diversion structure of the duct component of the present invention is simple in structure and cleverly designed. It can prevent the condensed water of the volute 12 from dripping under the air conditioner to ensure the safety of the whole machine, and can improve the efficiency of the volute cover 13 in diverting water to the water receiving tray 20, and has a very large development prospect.

[0041] A second embodiment of the present invention provides an air conditioner indoor unit including an air duct installation structure, and the air duct installation structure is the air duct installation structure provided in the above embodiment.

[0042] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the present invention designs a water diversion structure for inclined assembly of the air duct. The effects achieved are as follows: the air duct component and the air inlet panel are assembled at a certain inclination angle, and the assembly inclination angle α is greater than the draft angle β of the water receiving surface of the volute water receiving structure, which can effectively prevent the drainage surface of the volute water diversion structure of the air duct component from tilting outward, causing the condensed water generated in the volute to flow outward, and ensure that the condensed water of the volute flows to the water receiving structure of the volute cover. At the same time, the angle of the water receiving surface of the volute cover water receiving structure can be increased, so that the condensed water on the volute cover can flow more easily to the water receiving tray. This structure effectively ensures that the condensed water in the air duct flows to the water receiving tray, ensuring the safety and reliability of the entire machine.
