Abstract
Description
Technical Field
[0001] This invention relates to the field of indoor unit design technology, and more specifically, to an indoor unit and an air conditioner having the same. Background Technology
[0002] The water pump and level switch of a ducted air conditioner are usually mounted on the side panel. After-sales maintenance of the ducted air conditioner requires first unscrewing the screws on the side panel, which is difficult. Furthermore, the wires of the water pump and level switch may be tangled with other parts, further complicating the repair process. After-sales maintenance typically requires disassembling the electrical box, which necessitates removing the screws from the side panel cover and then removing the main board's fixing screws. This cumbersome and difficult process results in inefficient simultaneous reassembly.
[0003] There is currently no effective solution to the aforementioned problems in the existing technology. Summary of the Invention
[0004] The main objective of this invention is to provide an air conditioner that solves the problem of difficult disassembly and assembly of components such as the water pump, liquid level switch, and electrical box of the indoor unit during maintenance in the prior art.
[0005] To achieve the above objectives, according to one aspect of the present invention, an indoor unit is provided, comprising: a housing having a receiving cavity; a fan disposed within the receiving cavity via a fan mounting plate, the housing including a side plate, with an installation space formed between the fan and the side plate; and a mounting bracket located within the installation space, the mounting bracket being detachably connected to the fan mounting plate, the mounting bracket being used to mount at least one of a water pump assembly, an electrical main board, a level switch, and a drain pipe; wherein the mounting bracket has a locking position located within the installation space and connected to the fan mounting plate, and an unlocking position disengaged from the fan mounting plate.
[0006] Furthermore, the housing has an air outlet located on one side of the side panel, and when the mounting bracket is in the unlocked position, the mounting bracket is movably positioned in the direction toward the air outlet of the air conditioner.
[0007] Furthermore, the mounting bracket includes: an electrical box housing, which is an annular structure having at least one opening along its height direction, the annular structure forming an electrical box mounting cavity, and the electrical main board located inside the electrical box mounting cavity and detachably connected to the electrical box housing.
[0008] Furthermore, at least one mounting guide groove is provided on the side wall along the length direction of the electrical box housing, and the edge of the electrical main board is located in the mounting guide groove and is movably disposed along the height direction of the electrical box housing.
[0009] Furthermore, the two side walls in the width direction of the electrical box housing are set with different areas. The side wall with the larger area in the width direction of the electrical box housing is the connecting side wall. A liquid level switch bracket is provided on the side of the connecting side wall away from the electrical box mounting cavity. The liquid level switch bracket is used to install the liquid level switch.
[0010] Furthermore, a mounting groove is provided at the end of the liquid level switch bracket away from the connecting side wall, and the liquid level switch is located in the mounting groove and detachably connected to the liquid level switch bracket.
[0011] Furthermore, a connecting plate is provided on the side of the connecting sidewall away from the liquid level switch bracket. One end of the connecting plate is connected to the connecting sidewall, and the other end of the connecting plate extends away from the connecting sidewall.

[0041] Combination Figures 1 to 9 As shown, according to a specific embodiment of this application, an indoor unit is provided.
[0042] The indoor unit includes a housing 10, a fan 20, and a mounting bracket 30. The housing 10 has a receiving cavity. The fan 20 is disposed within the receiving cavity via a fan mounting plate 40. The housing 10 includes a side plate 11. A mounting space 12 is formed between the fan 20 and the side plate 11. The mounting bracket 30 is located within the mounting space 12. The mounting bracket 30 is detachably connected to the fan mounting plate 40. The mounting bracket 30 is used to mount at least one of a water pump assembly 41, an electrical main board 42, a level switch 43, and a drain pipe 44. The mounting bracket 30 has a locking position located within the mounting space 12 and connected to the fan mounting plate 40, and an unlocking position detached from the fan mounting plate 40.
[0043] By applying the technical solution of this invention, the mounting bracket 30 is disposed within the mounting space 12 formed between the fan 20 and the side plate 11, and is detachably connected to the fan mounting plate 40. This allows the indoor unit to be repaired without first removing the side plate or other structures. The water pump assembly 41, electrical main board 42, liquid level switch 43, and drain pipe 44 can be directly disassembled and assembled as a single unit. This avoids the situation where the wires of the water pump assembly 41, liquid level switch 43, and other components are tightly bound to other parts, making disassembly difficult, and effectively improves the disassembly and assembly efficiency of the aforementioned components. The technical solution of this application effectively solves the problem of difficult disassembly and assembly of components such as the water pump, liquid level switch, and electrical box in the prior art during maintenance.
[0044] Specifically, the mounting bracket 30 and the fan mounting plate 40 are connected by a snap-fit mechanism. When maintenance personnel need to disassemble the mounting bracket 30, they can manually contact the connection between the two. Indoor units include ducted units, which are connected to the outdoor unit via ductwork. Figure 1 The two main components of the ducted air conditioning unit are shown: the fan 20 and the evaporator 103, with the fan mounting plate 40 located between the fan 20 and the evaporator 103. Figure 1 and Figure 5 The lower cover plate 100, the upper cover plate 101, and the return air plate 102 are also shown.
[0045] Furthermore, the housing 10 has an air outlet 90. The air outlet 90 is located on one side of the side panel 11. When the mounting bracket 30 is in the unlocked position, the mounting bracket 30 is movably positioned in the direction toward the air outlet 90 of the air conditioner. This arrangement allows the mounting bracket 30 to be pulled out without the need for a separate outlet in the housing 10, facilitating maintenance operations by after-sales personnel.
[0046] Furthermore, the mounting bracket 30 includes an electrical box housing 31. The electrical box housing 31 is an annular structure with at least one opening 311 along its height direction. The annular structure encloses an electrical box mounting cavity 312. The electrical main board 42 is located within the electrical box mounting cavity 312 and is detachably connected to the electrical box housing 31. This arrangement allows the electrical box housing 31 to provide good protection for the electrical main board 42, preventing it from getting damp or having impurities enter.
[0047] Specifically, at least one mounting guide groove 32 is provided on the side wall along the length of the electrical box housing 31. The edge of the electrical main board 42 is located within the mounting guide groove 32 and is movably disposed along the height direction of the electrical box housing 31. This embodiment facilitates the disassembly and installation of the electrical main board 42 by after-sales personnel.
[0048] Furthermore, the two sidewalls of the electrical box housing 31 have different areas in the width direction. The sidewall with the larger area in the width direction of the electrical box housing 31 is the connecting sidewall 313. A liquid level switch bracket 50 is provided on the side of the connecting sidewall 313 facing away from the electrical box mounting cavity 312. The liquid level switch bracket 50 is used to install the liquid level switch 43. The connecting sidewall 313 can ensure the connection strength between the various parts of the mounting bracket 30 and prevent the wires between the various parts from being tightly bound.
[0049] Furthermore, a mounting groove 51 is provided at the end of the level switch bracket 50 away from the connecting side wall 313. The level switch 43 is located within the mounting groove 51 and is detachably connected to the level switch bracket 50. The mounting groove 51 improves the connection stability between the level switch 43 and the level switch bracket 50.
[0050] A connecting plate 60 is provided on the side of the connecting sidewall 313 away from the liquid level switch bracket 50. One end of the connecting plate 60 is connected to the connecting sidewall 313. The other end of the connecting plate 60 extends away from the connecting sidewall 313. A through-hole 61 is provided on the connecting plate 60, through which the drain pipe 44 passes and connects to the water pump assembly 41. This arrangement can fix and guide the drain pipe 44, facilitating the overall installation and disassembly.
[0051] In an optional embodiment, the housing 10 is provided with a clearance hole 80, and the drain pipe 44 passes through the clearance hole 80 and communicates with the outside.
[0052] Furthermore, the mounting bracket 30 also includes a pump mounting bracket 70. The pump mounting bracket 70 is connected to both the connecting side wall 313 and the connecting plate 60. The pump mounting bracket 70 is used to mount the pump assembly 41.
[0053] Optionally, when the air outlet 90 of the air conditioner is located on one side of the width direction of the housing 10, a roller is provided between the mounting bracket 30 and the housing 10, and the mounting bracket 30 is movably arranged toward the air outlet 90 via the roller.
[0054] Furthermore, the electrical box housing 31, the level switch bracket 50, the connecting plate 60, and the water pump mounting bracket 70 are integrally formed. In fact, making the electrical box housing 31, the level switch bracket 50, the connecting plate 60, and the water pump mounting bracket 70 into an integral structure can improve the after-sales disassembly and assembly efficiency and the production assembly efficiency of the duct air conditioner.
[0055] In an optional embodiment, the electrical box housing 31, the liquid level switch bracket 50, the connecting plate 60, and the water pump mounting bracket 70 can be set separately and assembled together by means of screws or glue.
[0056] Optionally, the mounting bracket 30 can be further connected to the housing 10 by fixing screws.
[0057] The assembly sequence of the mounting bracket 30 and its components is as follows: First, install the level switch 43 into the level switch bracket 50. Next, fix the water pump assembly 41 onto the water pump mounting bracket 70. Then, pass the drain pipe 44 through the pipe hole 61 and assemble the drain pipe 44 into the water pump drain port. Finally, use screws to fix the drain pipe connector onto the mounting bracket 30. After the mounting bracket 30 and its components are assembled, install the mounting bracket 30 into the installation space 12. Then, assemble the side plate 11 onto the upper cover plate 101, and finally, make the side plate 11 make way for the drain pipe 44.
[0058] In an optional embodiment, the disassembly sequence of the mounting bracket 30 is as follows: Figures 5 to 7 The diagram illustrates the sequence of steps for removing the mounting bracket 30 from the indoor unit. First, disconnect the drain pipe 44 from the water pump drain connector, then loosen the fixing screws of the mounting bracket 30. Next, pull the mounting bracket 30 outwards, and then move the mounting bracket 30 towards the fan blades. Figure 6 As shown, finally pull out the entire mounting bracket 30 as shown. Figure 7 As shown. Figure 5 The arrow in the image indicates the direction of the air outlet. At this time, the mounting bracket 30 can be pulled out through the air outlet.
[0059] In another alternative embodiment, the disassembly sequence of the mounting bracket 30 is as follows: Figures 8 to 9The diagram illustrates the steps involved in removing the mounting bracket 30 from the indoor unit. First, disconnect the drain pipe 44 from the water pump drain connector, remove the lower return air panel, and then loosen the fixing screws of the mounting bracket 30. Next, pull the mounting bracket 30 outwards, then move it towards the fan blades, and finally lift the entire mounting bracket 30 upwards. Figure 9 The arrow in the image indicates the direction of the air outlet. At this time, the mounting bracket 30 can be pulled out through the air outlet.
