Referring to fig. 1 to 4, fig. 1 is a schematic view of a wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, fig. 2 is a schematic view of an internal structure of the wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, in which a casing 10 is hidden, fig. 3 is an exploded view of a part of a component of the wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, and fig. 4 is a schematic view of a duct frame 20 of the wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention.

The utility model provides a wall-hanging air conditioning indoor set 1, this wall-hanging air conditioning indoor set 1 generally can include casing 10, wind channel skeleton 20, evaporimeter 30 and cross-flow fan 40.

The casing 10 protects the whole wall-mounted air conditioner indoor unit 1, an air inlet 12 can be formed in the top of the casing 10, and an air outlet 14 is formed in the lower portion of the front side of the casing 10 along the transverse direction.

The air duct frame 20 is disposed inside the casing 10, a heat exchange air duct 222 extending in a transverse direction is formed on the air duct frame 20, and the heat exchange air duct 222 has an air inlet side opening toward the heat exchange airflow inlet and an air outlet side opening toward the air outlet 14.

The cross-flow fan 40 is transversely installed in the heat exchange air duct 222, and is used for promoting indoor airflow to enter the casing 10 from the air inlet 12 to exchange heat with the evaporator 30, and finally to be discharged from the air outlet 14.

The evaporator 30 is installed on the air duct frame 20, covers the heat exchange air duct 222, and is located between the casing 10 and the cross flow fan 40 to exchange heat with the air sucked into the casing 10, and the air after heat exchange is driven by the cross flow fan 40 to be discharged into the room through the air outlet side of the air duct frame 20 and the heat exchange airflow outlet of the casing 10, so as to realize cooling or heating.

In some embodiments, the evaporator 30 may also be a three-stage configuration (as shown in FIG. 3) that includes a rear section 32 mounted to the duct skeleton 20. Since the evaporator 30 condenses moisture in the air during cooling and forms condensed water, in order to collect and discharge the condensed water, the duct frame 20 forms a rear water pan 240 behind the heat exchange duct 222, a drain hole 242 is formed in a bottom wall of the rear water pan 240, and a bottom of the rear section 32 is disposed in the rear water pan 240, so that the condensed water formed thereon can be drained into the rear water pan 240 and discharged from the drain hole 242.

Further, in order not to affect the flow of the condensed water in the rear drip tray 240, a passage gap is generally required between the bottom end of the rear section 32 of the evaporator 30 and the bottom wall of the rear drip tray 240 to flow out. However, due to the passage gap, the indoor air can enter the rear drain pan 240 through the drain hole 242 and then directly enter the heat exchange air duct 222 without passing through the evaporator 30, which may cause uneven heat exchange in the heat exchange air duct 222, and may easily form condensation, resulting in water dripping and leaking of the air conditioner.

Referring to fig. 4 to 7, fig. 4 is a schematic view of a duct frame 20 in a wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, fig. 5 is an a-portion enlarged view of the duct frame 20 shown in fig. 4, which shows a position of a wind blocking portion 50, fig. 6 is a cross-sectional view of the duct frame 20 in the wall-mounted air conditioner indoor unit 1 according to an embodiment of the present invention, and fig. 7 is a B-portion enlarged view of the duct frame 20 shown in fig. 6, which shows a structure of the wind blocking portion 50.

In order to overcome the above problem, the wall-mounted air conditioning indoor unit 1 of the present embodiment includes a windshield 50 in the rear drain pan 240 for blocking the entrance of indoor air.

Specifically, wind blocking portion 50 is disposed in rear water collector 240 at water discharge hole 242, wind blocking portion 50 includes a first partition panel 52 covering above water discharge hole 242 and a second partition panel 54 extending from one lateral end of first partition panel 52 toward water discharge hole 242, and wind blocking portion 50 blocks at least a portion of indoor air entering rear water collector 240 through water discharge hole 242 by using first partition panel 52 and second partition panel 54.

In this embodiment, since first partition panel 52 covers drain hole 242 and second partition panel 54 extends from one lateral end of first partition panel 52 toward drain hole 242, indoor air entering rear drain pan 240 from drain hole 242 first contacts first partition panel 52 and second partition panel 54, such that first partition panel 52 blocks indoor air from entering rear drain pan 240 and then continues to flow upward, and second partition panel 54 blocks indoor air from entering rear drain pan 240 and then flows to the side.

That is, the wind blocking portion 50 is disposed at the water discharge hole 242, and may block a flow path of indoor air by using the first partition plate 52 and the second partition plate 54, so as to reduce the mobility of indoor air entering the rear drain pan 240 from the water discharge hole 242, reduce an amount of air entering the heat exchange air duct 222 without passing through the evaporator 30, improve the heat exchange uniformity of the heat exchange air duct 222, and reduce the probability of condensation.

Referring to fig. 7, further, since the second partition plate 54 extends from one lateral end of the first partition plate 52 toward the drain hole 242, in order not to interfere with the flow of the condensed water collected in the rear drip tray 240 toward the drain hole 242, a flow-passing gap 58 is provided between the end of the second partition plate 54 and the bottom wall of the rear drip tray 240.

That is, the bottom end of the second partition plate 54 is not connected to the bottom wall of the rear drain pan 240, and the bottom end of the second partition plate 54 and the bottom wall of the rear drain pan 240 leave the flow passage gap 58, so that the condensed water in the rear drain pan 240 can smoothly flow to the drain hole 242 without being affected by the second partition plate 54.

Referring to fig. 7, further, the height H of the flow-passing gap 58 may be configured to be not less than 6mm, for example, 6mm, 7mm or more, so that the normal drainage of the condensed water can be ensured.

Referring to fig. 7, in some embodiments, the number of the second partition plates 54 is two, and two second partition plates 54 are respectively positioned right above two sidewalls of the water drain holes 242.

That is, the two second partition panels 54 extend from the two lateral ends of the first partition panel 52 toward the drain hole 242, so that firstly, the flowability of the indoor air flowing to both sides can be further reduced, and secondly, because the two second partition panels 54 are formed at the two lateral ends of the first partition panel 52, the first partition panel 52 and the two second partition panels 54 can form a buffer inner cavity 59, so that the indoor air entering the rear drip tray 240 from the drain hole 242 can firstly enter the buffer inner cavity 59, and thus the buffer inner cavity 59 can delay the speed of the indoor air flowing to the inside of the rear drip tray 240, and further reduce the flowability of the indoor air entering the rear drip tray 240 from the drain hole 242.

Referring to fig. 7, further, the wind blocking portion 50 may further include a third partition plate 56, the third partition plate 56 being located between the two second partition plates 54, and the third partition plate 56 extending from a lower surface of the first partition plate 52 into the water discharge hole 242 to partition the water discharge hole 242 into two water discharge areas 242a, 242 b.

Since the second partition plate 54 and the bottom wall of the rear drip tray 240 have the flow passing gap 58 therebetween, the third partition plate 56 directly extends into the inside of the drainage hole 242, that is, the length of the third partition plate 56 is greater than that of the two second partition plates 54. When water is drained, the condensed water collected in the rear drain pan 240 flows into the drain regions 242a and 242b, respectively, from both sides of the third partition plate 56.

In addition, since the third partition plate 56 divides the water discharge hole 242 into two water discharge regions 242a and 242b, the indoor air is divided into two parts by the third partition plate 56 after entering the water discharge hole 242, so that the passage of the drip tray 240 is narrower after the indoor air flows, and the fluidity of the indoor air is further reduced.

Referring to fig. 4, in some embodiments, the duct skeleton 20 may further include a rear body 210 extending vertically, and a volute portion 220 disposed in front of the rear body 210, the volute portion 220 is used to form a heat exchange duct 222, and a rear end of the volute portion 220 and an inner wall of the rear body 210 form a front wall and a rear wall of the rear water pan 240, respectively.

Referring to fig. 5, further, a front end of the wind blocking portion 50 is connected to a front wall of the rear drip tray 240, and a rear end of the wind blocking portion 50 is connected to a rear wall of the rear drip tray 240.

Specifically, the front and rear ends of the first, second, and third partition plates 52, 54, and 56 may be connected to the front and rear walls of the rear drip tray 240, respectively, so that it may be ensured that indoor air cannot enter the rear drip tray 240 from the front and rear ends of the wind blocking portion 50.

In some specific embodiments, the rear main body 210 and the volute portion 220 in the air duct skeleton 20 are integrally formed, and form the rear water pan 240, and the wind blocking portion 50 may also be integrally formed with the rear main body 210 and the volute portion 220, so as to simplify installation, improve sealing performance between components, and achieve better effect.

Referring to fig. 3 and 4, further, the duct skeleton 20 is further formed with a front water pan 250 located in front of the heat exchange duct 222, and the evaporator 30 may further include a middle section 34 and a front section 36, a rear end of the middle section 34 is connected to the rear section 32 and extends downward from the rear to the front, and a rear end of the front section 36 is connected to a front end of the middle section 34 and extends downward such that the front end thereof is disposed in the front water pan 250.

Because the bottom of the front section 36 is disposed in the front drip pan 250, the condensed water generated on the front section 36 can be drained into the front drip pan 250, and the bottom wall of the front drip pan 250 can be provided with at least one drainage hole 242 so as to drain the condensed water collected therein.

The bottom ends of the rear section 32 and the front section 36 are respectively arranged in the rear water pan 240 and the front water pan 250, the middle section 34 is located between the rear section 32 and the front section 36, and the rear water pan 240 and the front water pan 250 are respectively located behind and in front of the volute portion 220, so that after the evaporator 30 is installed, the rear section 32, the middle section 34 and the front section 36 are bent to cover the air inlet side of the volute portion 220, so that the air entering the heat exchange air duct 222 can exchange heat.

Referring to fig. 4, specifically, the duct skeleton 20 is formed with a water baffle 230 in front of the volute portion 220, and the front end of the volute portion 220 and the water baffle 230 together define a front water pan 250.

The water baffle fence 230 may include a laterally extending plate opposite to the front end of the scroll part 220 and side walls formed at both sides of the laterally extending plate, so that the water baffle 230 and the front wall of the scroll part 220 may form a front drain pan 250.

Further, a protrusion (not shown) may be formed in the front drip pan 250, and the protrusion may be used to assist in fixing the front section 36 of the evaporator 30 and prevent the front drip pan 250 from sliding.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
