Description

Technical Field

[0001] This utility model relates to high-temperature air conditioning, specifically to an openable horizontal indoor unit. Background Technology

[0002] In recent years, the high-temperature air conditioning market has become increasingly competitive, with a growing variety of high-temperature air conditioners available. However, for most high-temperature air conditioners currently on the market, there is a significant inconvenience when inspecting and maintaining key components such as fans, system piping, and heat exchangers: due to the large size of the fans themselves, they significantly obstruct the disassembly of other components. This forces maintenance personnel to first remove and move the fans out of the equipment before they can operate on other parts. This additional disassembly step not only makes the maintenance process lengthy and cumbersome but also significantly increases the time cost and operational difficulty of installation and maintenance, causing numerous problems for maintenance work in actual use. Utility Model Content

[0003] To address the aforementioned issues, this utility model employs a detachable door panel design. A linkage mechanism allows the door panel and fan to open and close synchronously, simplifying disassembly, improving maintenance efficiency, ensuring convenient access to all components, and reducing installation complexity. The specific solution is as follows:

[0004] An openable horizontal indoor unit includes a horizontal frame, with the front and rear sides of the frame being the air inlet and air outlet sides, respectively. A first pipe connector and a second pipe connector are located on the left side of the horizontal frame. A cooling system connected between the first and second pipe connectors is located within the horizontal frame.

[0005] The front panel of the horizontal rack consists of a rectangular frame and a door panel. The door panel has an air hood that is recessed into the horizontal rack. One side of the air hood is rotatably connected to the rectangular frame via a hinge, and the other side has a rotating handle. The door panel is locked by rotating the handle after it is closed.

[0006] The inner panel of the air outlet hood has an opening, and a DC inverter fan is fixedly installed on the inner panel of the air outlet hood. The air outlet of the DC inverter fan is connected to the opening, and an air guide grille is installed on the outer side of the door panel by magnetic attraction.

[0007] A frame-type filter screen can be detachably installed on the rear side of the horizontal frame.

[0008] Furthermore, the rotating handle consists of a rotating shaft, a handle, and a buckle. The rotating shaft is installed through and on the other side of the air vent. The handle and the buckle are fixedly installed at both ends of the rotating shaft and are located on the inner and outer sides of the door panel, respectively. The handle drives the buckle to rotate, so that the buckle spans between the rectangular frame and the door panel.

[0009] Furthermore, the handle and the buckle are distributed at 90°, with the buckle in the locked position when in the lateral position;

[0010] A torsion spring connects the rotating shaft and the air outlet cover. The torsion spring is sleeved on the rotating shaft and its two ends are connected to the rotating shaft and the air outlet cover respectively. When the rotating handle is not under force, the torsion spring keeps it in a horizontal position.

[0011] Furthermore, the rectangular frame has an embedded rectangular groove, so that the door panel is flush with the rectangular frame when closed.

[0012] Furthermore, the rear side of the horizontal frame is provided with two L-shaped retaining strips, one above the other, which form a transverse sliding groove. The frame-type filter screen is slidably installed in the transverse sliding groove.

[0013] Furthermore, the cooling system includes an evaporator installed on the air inlet side, and a water collection tray located at the bottom of the evaporator is provided on the horizontal frame.

[0014] Furthermore, the water receiving tray is equipped with an inclined bottom plate, with the left side of the inclined bottom plate being the lower side and equipped with a drain outlet. The left side of the horizontal frame is equipped with a drain pipe connected to the drain outlet.

[0030] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0031] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0032] Reference Figure 1-4 As shown, this utility model provides an openable horizontal indoor unit, which includes a horizontal frame 1. The front and rear sides of the horizontal frame 1 are the air inlet side and the air outlet side, respectively. A first pipe joint 2 and a second pipe joint 3 are provided on the left side of the horizontal frame 1. A cooling system 4 connected between the first pipe joint 2 and the second pipe joint 3 is provided inside the horizontal frame 1.

[0033] The front panel of the horizontal frame 1 consists of a rectangular frame 5 and a door panel 6. The door panel 6 is provided with an air hood 7 that is recessed into the horizontal frame 1. One side of the air hood 7 is rotatably connected to the rectangular frame 5 via a hinge 8, and the other side is provided with a rotating handle 9. When the door panel 6 is closed, the door panel 6 can be firmly locked onto the rectangular frame 5 by operating the rotating handle 9, ensuring the overall stability and sealing of the front panel.

[0034] like Figure 5 As shown, the inner panel 71 of the air outlet hood 7 has an opening 72, and a DC inverter fan 10 is fixedly installed on the inner panel of the air outlet hood 7. The air outlet of the DC inverter fan 10 is connected to the opening 72. A spiral magnetic strip 141 is fixed to the outer side of the door panel 6, which is used to quickly install the air guide grille 14. The air guide grille 14 is fixed by magnetic attraction, which is convenient for replacement and disassembly for cleaning.

[0035] The horizontal frame 1 has two L-shaped clips 11 on its rear side, one above the other. The two L-shaped clips 11 form a transverse groove. The frame filter 12 is slidably installed in the transverse groove. The frame filter 12 is installed on the rear side of the horizontal frame 1 by sliding insertion, which is convenient and quick.

[0036] like Figure 3 As shown, the rotating handle 9 consists of a rotating shaft 91, a handle 92, and a latch 93. The rotating shaft 91 is installed through and on the other side of the air outlet hood 7. The handle 92 and the latch 93 are fixedly installed at both ends of the rotating shaft 91 and are located on the inner and outer sides of the door panel 6, respectively. Rotating the handle 9 causes the latch 93 to rotate, so that the latch 93 spans between the rectangular frame 5 and the door panel 6. Preferably, the handle 92 and the latch 93 are distributed at 90°. When the latch 93 is in a horizontal position, it can lock between the rectangular frame 5 and the door panel 6. To ensure that the rotating handle 9 remains locked when no external force is applied, a torsion spring (not shown in the figure) is connected between the rotating shaft 91 and the air outlet hood 7. The torsion spring is sleeved on the rotating shaft 91, and its two ends are connected to the rotating shaft 91 and the air outlet hood 7, respectively. With the help of the torsion spring's elasticity, the latch 93 can always remain horizontally locked in its natural state, effectively preventing the door panel 6 from being opened accidentally and improving the safety and reliability of the equipment.

[0037] Meanwhile, the design also features anti-misoperation functionality: when the door panel 6 is open, the torsion spring causes the latch 93 to be in a horizontal position, preventing the door panel from closing directly due to the obstruction of the latch 93; the door panel can only be closed after the handle 92 is rotated to adjust the latch position, preventing the situation of closing the door without locking it. Furthermore, the torsion spring design also facilitates one-handed operation: rotating the handle 92 with one hand makes the latch 93 vertical, pushing the door panel 6 inward to close the horizontal frame 1, and then releasing the hand allows the torsion spring to automatically rotate the rotating shaft, resetting the latch 93 to the horizontal locking position. The entire opening, closing, and locking process can be completed with one hand, making operation efficient and convenient.

[0038] In an optional embodiment, the rectangular frame 5 is provided with an embedded rectangular groove 51 (e.g. Figure 4 This design ensures that the door panel 6 is flush with the rectangular frame 5 when closed. This results in a smoother and more aesthetically pleasing front panel appearance, reducing the space occupied by protruding parts and visual obtrusiveness. Furthermore, it enhances the sealing of the front panel to some extent, reducing airflow leakage and improving equipment efficiency.

[0039] Continue reading Figure 4 The cooling system 4 includes an evaporator 41, which is installed on the air inlet side of the horizontal frame 1 to cool the incoming air. To collect the condensate generated by the evaporator 41 during operation, a drip tray 42 is installed inside the horizontal frame 1 at the bottom of the evaporator 41. The base plate of the drip tray 42 is designed to be inclined, with the left side being the lower side. A drain outlet 43 is located on the lower side. A drain pipe 13 is also installed on the left side of the horizontal frame 1, connected to the drain outlet 43, to promptly drain the condensate collected in the drip tray 42, preventing condensate from accumulating inside the equipment and affecting its normal operation.

[0040] In summary, the openable horizontal indoor unit provided by this utility model adopts an openable structure that links the door panel and the fan, and is equipped with a rotating handle locking mechanism. Simply opening the door panel will simultaneously move the fan out of the housing, greatly simplifying the maintenance process of internal components. The sliding installation of the frame-type filter and the magnetic installation of the air guide grille facilitate quick disassembly and maintenance. The inclined base plate of the water tray and the drainage pipe effectively solve the problem of condensate drainage.
