[0034] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0035] The following is for reference. Figures 1-13 This invention describes a window air conditioner according to an embodiment of the present invention.

[0036] like Figures 1-13 As shown, the window air conditioner 100 according to an embodiment of the present utility model includes: a casing 10, a compressor, an outdoor heat exchanger, an outdoor fan, an indoor heat exchanger 20, an indoor fan, and a water collection tray 30.

[0037] The casing 10 is an external frame of the window air conditioner 100, which can protect other internal components from the external environment and ensure the appearance of the window air conditioner 100.

[0038] The compressor can compress the refrigerant into high-temperature and high-pressure gas, which is then cooled and liquefied by the outdoor heat exchanger.

[0039] The outdoor heat exchanger, i.e., the condenser, is located on the outside of the window air conditioner 100 and can dissipate heat to the external air when the gas passes through, thereby converting the high-temperature and high-pressure gas into liquid.

[0040] The outdoor fan can promote the flow of air around the outdoor heat exchanger, i.e., the outdoor fan drives the outdoor air to enter the casing 10 from the outdoor air inlet, and the outdoor air flows back to the outside from the outdoor air outlet after heat exchange with the outdoor heat exchanger, which can improve the heat dissipation efficiency of the window air conditioner 100 and ensure the effectiveness of the condensation process.

[0041] The indoor heat exchanger 20, i.e., the evaporator, is located on the inside of the window air conditioner 100, and the refrigerant absorbs heat from the indoor heat exchanger 20 after evaporating into gas, thereby reducing the indoor temperature.

[0042] The indoor fan can promote air circulation, and the indoor air is cooled by the evaporator and then returned to the room, i.e., the indoor fan drives the indoor air to enter the casing 10 from the indoor air inlet, and the indoor air flows back to the indoor from the indoor air outlet after heat exchange with the indoor heat exchanger 20, thereby achieving the cooling effect.

[0043] The water pan 30 is arranged below the indoor heat exchanger 20, which receives the condensate water generated by the indoor heat exchanger 20 and then discharges the condensate water outside the window air conditioner 100, thereby avoiding the condensate water flowing into the room.

[0044] Among them, the casing 10 is provided with an outdoor air inlet, an outdoor air outlet, an indoor air inlet and an indoor air outlet, the outdoor air inlet is used to draw fresh air from the external environment into the casing 10, and a filtering device is arranged at the outdoor air inlet, so that dust-free, pollen-free and other particulate matter can be introduced into the room.

[0045] The outdoor air outlet discharges the air cooled or heated to the outside of the room, i.e., the treated air is no longer suitable to return to the room, thereby adjusting the air quality in the room and avoiding the retention of stale or polluted air in the room.

[0046] The indoor air inlet can re-introduce the indoor air into the casing 10 for processing. For example, the indoor air needs to be reheated in winter and re-cooled in summer.

[0047] The indoor air outlet can send the treated fresh or recycled air back to the indoor room, thereby providing comfortable conditions for the user.

[0048] The compressor, the outdoor heat exchanger, the outdoor fan, the indoor heat exchanger 20, the indoor fan and the water pan 30 are all arranged in the casing 10, so that the casing 10 can protect the compressor, the outdoor heat exchanger, the outdoor fan, the indoor heat exchanger 20, the indoor fan and the water pan 30, thereby prolonging the service life of the compressor, the outdoor heat exchanger, the outdoor fan, the indoor heat exchanger 20, the indoor fan and the water pan 30, and not being affected by the external environment to affect their own performance.

[0049] The indoor heat exchanger 20 includes a front heat exchanger 21 and a rear heat exchanger 22, the front heat exchanger 21 is a heat exchanger close to the air inlet side, and the rear heat exchanger 22 is a heat exchanger at a downstream position of the front heat exchanger 21. The front heat exchanger 21 can preliminarily process the air entering the casing 10, and the rear heat exchanger 22 further processes the air, thereby making the air reach the temperature and humidity required by the user.

[0050] For example, in the cooling mode, the front heat exchanger 21 cools the relatively hot air outside, in the heating mode, the front heat exchanger 21 warms up the relatively cold air outside, and the rear heat exchanger 22 further accurately adjusts the air, thereby meeting the use requirements of the user.

[0052] The water pan 30 includes a water pan body 31 and a support rib 32, the front end of the rear heat exchanger 22 and the rear end of the front heat exchanger 21 are arranged on the water pan body 31, the support rib 32 is arranged at the bottom of the water pan body 31, and the support rib 32 is in abutting engagement with the bottom of the casing 10, thereby forming an air inlet channel between the water pan body 31 and the bottom of the casing 10, and part of the indoor air entering the casing 10 from the indoor air inlet flows to the rear heat exchanger 22 through the air inlet channel.

[0053] It can be understood that the water pan body 31 and the support rib 32 constitute the main structure of the water pan 30, the rear end of the front heat exchanger 21 and the front end of the rear heat exchanger 22 are close to each other, and the front end of the front heat exchanger 21 and the rear end of the rear heat exchanger 22 are away from each other, so that the cross section of the front heat exchanger 21 and the rear heat exchanger 22 forms a "V" shape, and the water pan body 31 is located at the tip of the "V" shape, so that the water pan body 31 can collect the condensed water generated by the front heat exchanger 21 and the rear heat exchanger 22.

[0054] The support rib 32 is located at the bottom of the water pan body 31, so that the support rib 32 protrudes relative to the bottom of the water pan body 31, thereby facilitating the abutting fit of the support rib 32 and the bottom of the cabinet 10, not only can the support rib 32 limit the assembly process of the water pan body 31 and the cabinet 10, but also can form a gap between the water pan body 31 and the cabinet 10, and the gap forms an air inlet channel.

[0055] The indoor air flows into the cabinet 10 through the air inlet channel, that is, the indoor air entering the cabinet 10 from the indoor air inlet flows to the rear heat exchanger 22 through the air inlet channel, which can promote the circulation of air in the cabinet 10, and also can increase the volume of air contacting the rear heat exchanger 22, thereby improving the heat exchange efficiency of the indoor heat exchanger 20, and further facilitating the user to accurately control the indoor temperature and humidity.

[0059] As shown in Figure 5 , Figures 9-11 and Figure 13 , the water pan body 31 comprises a front plate 311, a middle plate 312 and a rear plate 313, the front plate 311 is arranged to be inclined downward in the front-to-back direction, the front end of the rear heat exchanger 22 and the rear end of the front heat exchanger 21 are arranged on the middle plate 312, the front plate 311 is connected to the front side of the middle plate 312, and the rear plate 313 is arranged to be inclined upward in the front-to-back direction and is connected to the rear side of the middle plate 312; wherein the support rib 32 extends from the front plate 311 to the rear plate 313, and the break 321 corresponds to the middle plate 312.
