Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically to a window air conditioner. Background Technology

[0002] Window air conditioners produce a large amount of condensate when switching from cooling to dehumidification. To ensure that the condensate can be effectively discharged to the outside of the unit, window air conditioners usually have a drain outlet on the outdoor side for direct discharge. However, because long-distance drainage is not possible, when the drainage volume is large, the condensate flows around randomly and may even flow back into the room. Although Chinese patent number CN110939990B discloses a chassis and a window air conditioner with spaced-out drain holes and overflow holes on the outside of the unit, allowing for drainage through both the overflow and drain holes when there is a large amount of water accumulation inside the chassis, the condensate from the overflow hole still drains in place, failing to solve the problem of large amounts of condensate flowing around during dehumidification.

[0039] Reference Figure 1-9 This invention describes a window air conditioner according to an embodiment of the present invention.

[0040] In one embodiment, such as Figure 1-9As shown, a window air conditioner includes an indoor unit 100 and an outdoor unit 200. The indoor unit 100 includes an evaporator assembly 1, and the outdoor unit 200 includes a condenser assembly 3. A water collection tray 5 is provided below the evaporator assembly 1 and the condenser assembly 3, and a base plate 6 is provided below the water collection tray 5.

[0041] The water receiving tray 5 is provided with a drain outlet 51, and the part of the base plate 6 located outside the room 200 is provided with a water storage tank 61. The drain outlet 51 is located above the water storage tank 61, and the bottom of the water storage tank 61 is provided with a first drain outlet 7 and a mounting boss 62.

[0042] The mounting boss 62 is provided with a second drainage structure 8, which includes a drain connector 81 and a water pipe connector 82. The lower end of the drain connector 81 passes through the second drain opening on the mounting boss 62 and connects with the water pipe connector 82. The water pipe connector 82 is used to connect a water pipe.

[0043] The window air conditioner unit consists of an indoor section 100 and an outdoor section 200, such as... Figure 1 As shown, when the window air conditioner is installed on the window 300, the indoor unit 100 and the outdoor unit 200 are located indoors and outdoors, respectively; the base plate 6 is the base plate of the window air conditioner body; the indoor unit 100 also includes an air inlet grille 11 and a front panel 12. The air inlet grille 11 is assembled at the front end of the front panel 12 to achieve air intake; the water tray 5 is used to receive the condensate generated by the evaporator assembly 1 and the condenser assembly 4, and then discharges the condensate into the water storage tank 61 through its drain outlet 51.

[0044] Specifically, the lower end of the drain connector 81 is provided with an external thread, and the upper end of the water pipe connector 82 is provided with an internal thread. The drain connector 81 and the water pipe connector 82 are connected by threads. The drain connector 81 can be fixedly installed on the mounting boss 62 by screws.

[0045] The working principle of the above-mentioned window air conditioner is as follows: The base plate 6 has a water storage tank 61 set in the part located outside the room 200, forming a water storage area at the bottom; when the air conditioner is working, the condensate produced by the evaporator assembly 1 and / or the condenser assembly 4 flows into the water receiving pan 5, and then flows into the water storage tank 61 on the base plate 6 through the drain outlet 51 of the water receiving pan 5, which can achieve the water storage effect; the first drain outlet 7 is used to drain the condensate stored in the water storage tank 61, which is suitable for situations where a small amount of condensate is discharged nearby, and the drainage volume is small and it is not easy to cause turbulence; the second drainage structure 8 is set on the mounting boss 62, and its corresponding second drain outlet is higher than the bottom of the water storage tank 61; the air conditioner will produce a large amount of condensate in the dehumidification mode. When the water level of the condensate is higher than the mounting boss 62, it can be drained through the second drain outlet. At the same time, in order to facilitate drainage, the water pipe connector 82 is connected to the drain connector 81. When using the dehumidification function of the air conditioner, a water pipe can be connected to the water pipe connector 82, so as to drain the condensate to a distant place outdoors, realizing the remote drainage function.

[0046] In one embodiment, a recess 63 is provided on the bottom surface of the water storage tank 61, a first drain outlet 7 is provided in the recess 63, and a drain outlet 51 is located above the recess 63.

[0047] The first drain outlet 7 is lower than the bottom surface of the water storage tank 61, and the horizontal area of ​​the recess 63 can be 10% to 30% of the horizontal area of ​​the water storage tank 61, thereby increasing the capacity of the water storage tank 61. It can also store and discharge a small amount of condensate without wetting the entire water storage tank 61.

[0048] In practice, condensate flows into the recess 63 through the drain 51 of the water receiving pan 5. The water level in the recess 63 can be lower than the bottom of the water storage tank 61. When the water volume is small, it can flow directly out from the first drain 7 without wetting the entire water storage tank 61, thereby avoiding excessive water accumulation in the bottom plate 1 and ensuring the safety and reliability of the window air conditioner.

[0049] In one embodiment, the edge of the first drain outlet 7 is provided with a first sealing ring 70 to seal and wrap the edge of the first drain outlet 7 to prevent corrosion.

[0050] In practice, the first drainage outlet 7 can also be connected to an external water pipe for remote drainage.

[0051] In one embodiment, the second drainage structure 8 further includes a second sealing ring 83, which is disposed between the drainage connector 81 and the mounting boss 62 to provide a sealing effect and effectively prevent water leakage.

[0052] The first sealing ring 70 and the second sealing ring 83 can be silicone or rubber sealing rings, preferably silicone sealing rings, which are durable, safe and environmentally friendly.

[0055] Specifically, the first motor 24 drives the centrifugal impeller 22 to rotate, causing air to flow. After the air absorbs heat through the evaporator assembly 1, it flows out from the air outlet of the impeller mounting shell, thus achieving cooling.

[0056] In this embodiment, the front air duct assembly 2 includes an air duct base 21, a centrifugal impeller 22, an air duct cover 23, a first motor 24, and a motor mounting bracket 25. It has a simple structure and is easy to install and disassemble.

[0059] In one embodiment, the air outlet of the duct cover 23 is provided with a metal mesh 230, which can evenly disperse the airflow and make the airflow more uniform. The metal mesh 230 can be iron mesh, stainless steel mesh, etc.

[0060] In one embodiment, the indoor unit 100 further includes a heat-insulating foam component 9, which is disposed between the impeller mounting shell and the outdoor unit 200 to prevent heat from the outdoor unit 200 from being transferred back to the indoor unit 100, ensuring thermal insulation and thereby improving the overall cooling capacity and energy efficiency of the unit.

[0061] Furthermore, the heat-insulating foam component 9 wraps around the bottom surface, left and right sides, and the side facing the outside 200, providing good heat insulation and further improving the overall performance of the machine.

[0062] In one embodiment, the outdoor unit 200 includes a rear air duct assembly 4; the rear air duct assembly 4 includes a motor bracket 41, a third motor 42, an air duct housing 43, and an axial fan blade 44; the motor bracket 41 is installed at one end of the air duct housing 43, the third motor 42 is mounted on the motor bracket 41, and the axial fan blade 44 is connected to the shaft of the third motor 42; the condenser assembly 3 is located at the other end of the air duct housing 43.
