[0042] Combination Figures 1 to 4 As shown, according to a specific embodiment of the present application, a flow guide structure is provided.

[0043] Specifically, Figure 1 As shown, the flow guide structure includes a flow guide body 10 and a flow guide member 40. The flow guide body 10 has a water guide structure 20, which is extended along the length direction of the flow guide body 10, and a wiring structure 30 is provided on one side of the water guide structure 20; the first end of the flow guide member 40 is connected to the flow guide body 10, and the second end of the flow guide member 40 is arranged away from the flow guide body 10, and the flow guide member 40 is arranged opposite to the wiring structure 30, and the flow guide member 40 guides the condensed water formed by the wire at the wiring structure 30 to the water guide structure 20.

[0044] The water diversion structure and the guide member are arranged on the drainage body. The water diversion structure is used to divert the condensed water to a preset position. The guide member can divert the condensed water formed by the wires at the wiring structure to the water diversion structure, and then divert it to the preset position through the water diversion structure. This arrangement can prevent the condensed water from dripping on the components and causing damage to the components. In particular, when the diversion structure is applied to the air conditioner, the condensed water generated by the upper air outlet of the air conditioner can be drained to the designated position through the diversion structure to prevent the condensed water from dripping on the electrical box. The relative arrangement of the diversion member and the wiring structure can make the condensed water formed by the wires of the wiring structure drip on the diversion member and flow into the water diversion structure. The arrangement of the diversion structure can prevent water droplets from dripping and splashing randomly when the equipment is in use, and prevent the internal electrical components from short-circuiting and burning due to contact with water.

[0045] The surface of the guide member 40 facing the wiring structure 30 is arranged at a distance from the wire passing through the wiring structure 30. The relative arrangement of the guide member and the wire at the wiring structure allows the condensed water formed by the wire to drip onto the guide member, thereby preventing the water droplets from splashing around and causing damage to the device.

[0046] The water diversion structure 20 includes a first retaining rib 51 and a second retaining rib 52. The first retaining rib 51 is connected to the drainage body 10, and the first retaining rib 51 is extended along the length direction of the drainage body 10. The second retaining rib 52 is connected to the drainage body 10, and the second retaining rib 52 is extended along the length direction of the drainage body 10. The second retaining rib 52 and the first retaining rib 51 are arranged at intervals to form a routing structure 30. The first end of the guide member 40 is connected to the drainage body 10 and one end of the second retaining rib 52 facing the first retaining rib 51. The water diversion structure 20 is located on the first side of the first retaining rib 51 and the second retaining rib 52, and the second end of the guide member 40 is extended toward the second side opposite to the first side. The first barrier rib and the second barrier rib are used to block the cold air generated when the internal components are working, so that the cold air will not pass over the guide member and contact the components on the other side, thereby protecting the electrical components from short circuits caused by water. The water diversion structure is located on the first side of the first barrier rib and the second barrier rib, and can drain the condensed water condensed by the cold air blocked by the first barrier rib and the second barrier rib. The setting of the guide member can make the water droplets dripping from the wires of the routing structure on the guide member immediately blocked by the second barrier rib and enter the water diversion structure.

[0047] Preferably, the water diversion structure 20 comprises a water diversion groove provided on the drainage body 10. The water diversion structure can be made into a groove shape or other shapes with drainage function, and can be changed accordingly according to actual conditions when used.

[0048] The water guide structure 20 includes a water guide surface 11 located at a first side of the first retaining rib 51 and the second retaining rib 52. The water guide surface can make the water droplets flow more smoothly and avoid the accumulation of water droplets.

[0049] In order to avoid other components during installation, a recessed portion 12 is provided in the middle of the guide horizontal plane 11 , and the recessed portion 12 is located on the first side of the second retaining rib 52 .

[0050] Since lines need to be arranged in the device, corresponding devices for clamping the wires are required, and at least one clamping hole 13 may be provided on the side of the lead-in horizontal plane 11 away from the second retaining rib 52 and the first retaining rib 51 .

[0051] The guide member 40 includes a first drainage rib 41. The first end of the first drainage rib 41 is connected to at least one of the drainage body 10 and the second retaining rib 52, and the second end of the first drainage rib 41 is arranged away from the drainage body 10. The surface of the first drainage rib 41 facing the first retaining rib 51 forms a guide surface 411, and the guide surface 411 guides the condensed water formed by the wire at the wiring structure 30 to the side where the water diversion structure 20 is located. The first drainage rib is connected to at least one of the drainage body and the second retaining rib, so that after the condensed water drips on the guide surface, it flows down along the guide surface 411 and enters the water diversion structure.

[0052] The guide member 40 includes a second guide rib 42. The first end of the second guide rib 42 is connected to the guide body 10, the second end of the second guide rib 42 is extended along the length direction of the guide body 10, and the second end of the second guide rib 42 is located at the second side. The second guide rib 42 is used to receive water droplets formed by the wires of the routing structure 30 and guide the water droplets to the water diversion structure.

[0053] Preferably, the second end of the second drainage rib 42 is spaced apart from the drainage body 10. Such a configuration can form a plurality of drainage channels on the drainage body 10, which can disperse condensed water and reduce the thickness of condensed water formed on the drainage body 10, thereby improving the drainage efficiency of the drainage body 10.

[0054] The plane where the drainage surface of the second drainage rib 42 is located is set at an angle with the drainage surface of the water diversion structure 20. The drainage surface of the second drainage rib and the drainage surface of the water diversion structure are set at an angle, so that after the second drainage rib receives the water drop, the water drop immediately changes its flow direction at the angle and flows down along the water diversion structure. This arrangement can speed up the flow of condensed water.

[0055] The flow guiding structure includes a third retaining rib 53. The third retaining rib 53 is arranged opposite to the first retaining rib 51, and a flow guiding inlet 60 is formed between the third retaining rib 53 and the first retaining rib 51. Such an arrangement can collect condensed water formed at the end of the flow guiding body 10 to the water guiding structure through the water guiding inlet 60, and then guide the condensed water to flow to a preset position through the water guiding structure, thereby effectively improving the reliability of the flow guiding structure.

[0056] At least one positioning hole 71 is formed on the drainage body 10, and the positioning hole 71 is located on the second side of the first retaining rib 51. The positioning hole can facilitate the installation of the drainage structure and fix the drainage structure to prevent movement.

[0057] A positioning hole 71 is formed at the first end of the drainage body 10, and a connecting hole 72 is formed at the second end of the drainage body 10. This arrangement can improve the installation stability of the drainage structure.

[0058] In this embodiment, the flow guide structure is integrally formed. The integrally formed setting can make the flow guide structure more convenient to process and save production costs. Among them, the flow guide structure is made of PET material, that is, the flow guide structure is a foam structure. PET material has high temperature resistance and excellent water-blocking performance, and also plays a role in heat preservation, which can prevent condensation from forming on the surface of the flow guide structure.

[0059] The flow guide structure in the above embodiment can also be used in the technical field of air-conditioning equipment, that is, according to another embodiment of the present invention, an indoor unit is provided, the indoor unit includes a flow guide structure, and the flow guide structure is the flow guide structure in the above embodiment. The indoor unit includes a bottom shell 81. The bottom shell 81 is provided with at least one angle frame 82 and a water receiving tray 83, and the flow guide structure is connected to the angle frame 82. The flow guide structure is used to guide the condensed water formed in the bottom shell 81 to the water receiving tray 83. Among them, in this embodiment, there are two angle frames 82, and the two angle frames 82 are respectively arranged at the left and right ends of the bottom shell. Since the cold air cannot pass through the angle frames at the left and right ends, the cold air is mainly discharged to the outside through the upwind port, so condensed water is easily generated at the upwind port. Connecting the flow guide structure with the angle frame can make the condensed water generated at the upwind port be blocked by the flow guide structure in time to avoid damage to the electrical components. The water receiving tray can receive water droplets flowing down from the flow guide structure.

[0060] The water diversion structure and the guide member are arranged on the drainage body. The water diversion structure is used to divert the condensed water to a preset position. The guide member can divert the condensed water formed by the wires at the wiring structure to the water diversion structure, and then divert it to the preset position through the water diversion structure. This arrangement can prevent the condensed water from dripping on the components and causing damage to the components. In particular, when the diversion structure is applied to the air conditioner, the condensed water generated by the upper air outlet of the air conditioner can be drained to the designated position through the diversion structure to prevent the condensed water from dripping on the electrical box. The relative arrangement of the diversion member and the wiring structure can make the condensed water formed by the wires of the wiring structure drip on the diversion member and flow into the water diversion structure. The arrangement of the diversion structure can prevent water droplets from dripping and splashing randomly when the equipment is in use, and prevent the internal electrical components from short-circuiting and burning due to contact with water.

[0061] In another embodiment of the present application, a groove structure is provided on the flow guide structure, and a line can pass through the groove structure, and the groove structure is mainly used for drainage. In the air conditioner, the cold air generated by the evaporator cannot pass over the angle frame from the left and right sides, so it is mainly discharged to the outside through the upwind vent to adjust the room temperature. Therefore, condensation water is easily generated at the upwind vent, and the condensation water easily drips onto the electrical devices on the side along the bottom shell structure. When a flow guide structure with a groove structure is installed in the air conditioner, the condensation water generated at the upwind vent will not flow to the electrical devices on the side of the air conditioner due to the obstruction of the flow guide structure, but will gather on the flow guide structure, flow into the water receiving tray at the bottom of the air conditioner along the groove structure on the flow guide structure, and be discharged to the outside along the drain pipe. The specific flow direction of the condensation water is as follows: Figure 2 Indicated by the arrow.

[0062] like Figure 4As shown, the guide structure is installed on the angle frame 82 of the evaporator 84, positioned with positioning columns and tightened with screws, and the foam is installed on the outside of the angle frame, so that the cold air generated by the evaporator 84 on the inner side of the angle frame 82 during operation will not pass over the angle frame and contact the electrical box located outside the angle frame, thereby avoiding the problem of condensation water in the electrical box causing short circuit of electrical components.

[0063] At the same time, since there is a line passing through the upper air outlet of the air conditioner, condensed water can easily flow into the electrical components in the electrical box through the line, so a U-shaped return bay A (such as Figure 3 As shown in the figure, the condensed water on the line cannot enter the electrical box, but drips outside the electrical box. A water receiving tray 83 is provided below the U-shaped return bay A to receive the condensed water generated by the return bay. However, as the number of electrical boxes increases, when the electrical boxes are stacked together, the water droplets drained from one electrical box will fall on another electrical box below, and the water will seep into the electrical box from the electrical box cover, causing electrical safety hazards. In this embodiment, the guide structure is provided with a guide member, which is located below each return bay to receive the condensed water dripping from the return bay and guide the condensed water to the water diversion structure 20, thereby protecting the electrical box below.

[0064] In the above embodiment, the guide structure can not only keep warm and reduce the formation of condensed water, but also drain the condensed water generated in other electrical boxes, which can effectively avoid electrical safety hazards and protect electrical components in the circuit.

[0065] In addition to the above, it should be noted that "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in conjunction with the embodiment included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in conjunction with any embodiment, it is claimed that the realization of such feature, structure or characteristic in conjunction with other embodiments also falls within the scope of the present invention.

[0066] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
