In some embodiments, as shown in FIG. 5 and FIG. 6, the inductor box cover 430 and the inductor box shell 420 are positioned by means of buckles, and are fixedly connected through fasteners.
For example, referring to FIG. 7, the inductor box shell 420 further includes a top plate 423 (which is called a shell top plate 423) and a clamping portion 424. The shell top plate 423 is fixedly connected to top of the shell side plate 421. The shell top plate 423 includes an extending portion 4231 covering the shell side plate 421. The clamping portion 424 is disposed on the extending portion 4231 of the shell top plate 423.
In some embodiments, the shell side plate 421 and the shell top plate 423 are both sheet metal components, and the shell side plate 421 and the shell top plate 423 are fixedly connected by means of welding. Alternatively, the shell side plate 421 and the shell top plate 423 are both made of acrylonitrile butadiene styrene plastic (ABS), which not only has good insulation performance but also has good fire resistance.
Referring to FIG. 6, the inductor box cover 430 includes a top plate 431 (which is called a cover top plate 431), a side plate 432 (which is called a cover side plate 432) and a buckle 433. The cover top plate 431 is disposed on top of the cover side plate 432. The buckle 433 is disposed on the cover side plate 432, and a position of the buckle 433 corresponds to a position of the clamping portion 424.
For example, referring to FIG. 5, one end of the buckle 433 is fixedly connected to the cover side plate 432, and another end of the buckle 433 extends downward to the position of the clamping portion 424, so as to clamp with the clamping portion 424. Therefore, the inductor box cover 430 may be fixed on the top of the inductor box shell 420, so as to achieve the fixation of the inductor box cover 430 and the inductor box shell 420.
It will be noted that, the inductor box shell 420 includes a plurality of clamping portions 424, the inductor box cover 430 includes a plurality of buckles 433 corresponding to the plurality of clamping portions 424. For example, referring to FIG. 7 and FIG. 8, the inductor box shell 420 includes two clamping portions 424, and the two clamping portions 424 are respectively disposed on two opposite extending portions 4231 of the shell top plate 423. Correspondingly, the inductor box cover 430 includes two buckles 433. The two buckles 433 are respectively clamped with the two clamping portions 424, so that the connection between the inductor box shell 420 and the inductor box cover 430 is more stable.
In some embodiments, as shown in FIGS. 7 and 8, the shell top plate 423 includes a fourth connecting hole 4232, and the cover top plate 431 includes a fifth connecting hole 4311. A position of the fifth connecting hole 4311 corresponds to a position of the fourth connecting hole 4231, and a fastener is inserted through the fifth connecting hole 4311 and the fourth connecting hole 4231, so that the inductor box shell 420 and the inductor box cover 430 may be fixedly connected to each other.
It will be noted that, the shell top plate 423 may include a plurality of fourth connecting holes 4231, and the cover top plate 431 includes a plurality of fifth connecting holes 4311 corresponding to the plurality of fourth connecting holes 4231.
It can be understood that, in some embodiments of the present disclosure, the inductor box shell 420 and the inductor box cover 430 are fixed through the buckle 433 and the clamping portion 424, and then the inductor box shell 420 and the inductor box cover 430 are fixedly connected by means of a fastener. In this way, the connection between the inductor box shell 420 and the inductor box cover 430 is simplified, so as to facilitate the assembly and disassembly of the inductor assembly 400.
In some embodiments, as shown in FIG. 7, the shell side plate 421 further includes a limiting portion 4211. The limiting portion 4211 protrudes from the shell side plate 421 in a direction away from the inductor 410. In a case where the inductor box shell 420 is fixedly connected to the inductor box cover 430, a lower end of the inductor box cover 430 abuts against the limiting portion 4211. Herein, the limiting portion 4211 and the clamping portion 424 may be located on a same shell side plate 421 or on different shell side plates 421.
It can be understood that, the limiting portion 4211 limits the inductor box cover 430 when the inductor box cover 430 is installed. In addition, the limiting portion 4211 may further play a role of identification during installation of the inductor box cover 430, so as to prevent the connection between the buckle 433 and the clamping portion 424 or between the fourth connecting hole 4231 and the fifth connecting hole 4311 from being misaligned.
In some embodiments, as shown in FIG. 7, the inductor box shell 420 further includes a first heat dissipation opening 425 and a second heat dissipation opening 426. The first heat dissipation opening 425 is disposed on the shell side plate 421, and penetrates through the shell side plate 421 along a thickness direction thereof. The second heat dissipation opening 426 is disposed on the shell top plate 423, and penetrates through the shell top plate 423 along a thickness direction thereof. In this way, heat generated during an operation of the inductor 410 may be discharged from the first heat dissipation opening 425 and the second heat dissipation opening 426.
It will be noted that, the first heat dissipation opening 425 is a strip-shaped through hole. The second heat dissipation opening 426 may be a circular or rectangular through hole, the present disclosure is not limited thereto.
In some embodiments, the inductor box shell 420 includes a plurality of first heat dissipation openings 425, and the plurality of first heat dissipation openings 425 are arranged at intervals along a height direction of the inductor box shell 420.
In some embodiments, referring to FIG. 7, the inductor box shell 420 further includes a plurality of first water blocking portions 427. The plurality of first water blocking portions 427 correspond to the plurality of first heat dissipation openings 425. Each first water blocking portion 427 extends from an upper edge of the first heat dissipation opening 425 to an outer side of the inductor box shell 420 and downward, so as to shield the first heat dissipation opening 425. Thus, it is possible to prevent rainwater from entering the inductor assembly 400 through the first heat dissipation opening 425 without affecting the heat dissipation.
In some embodiments, as shown in FIG. 7, the inductor box shell 420 includes a plurality of shell side plates 421, and the plurality of first heat dissipation openings 425 are disposed on at least two adjacent shell side plates 421 of the plurality of shell side plates 421, which is conducive to providing air convection in the inductor assembly 400 and improving the heat dissipation efficiency of the inductor 410.
In some embodiments, as shown in FIGS. 8 to 10, the inductor box cover 430 further includes a third heat dissipation opening 434 and a second water blocking portion 435. The third heat dissipation opening 434 communicates with the second heat dissipation opening 426. In this way, a part of the heat generated by the inductor 410 during operation may enter the inductor box cover 430 through the second heat dissipation opening 426, and then be discharged from the inductor assembly 400 through the third heat dissipation opening 434, which is conducive to improving the heat dissipation efficiency of the inductor 410. The second water blocking portion 435 is disposed at the third heat dissipation opening 434, and is configured to prevent rainwater from entering the inductor assembly 400 through the third heat dissipation opening 434, so that reliability of operation of the inductor 410 in rainy days is ensured.
For example, referring to FIGS. 6 and 8, the cover top plate 431 includes a third protruding portion 4312 extending upward. The third heat dissipation opening 434 is disposed on a side surface of the third protruding portion 4312. That is, an opening direction of the third heat dissipation opening 434 is substantially perpendicular to a height direction of the inductor assembly 400.
In some embodiments, referring to FIG. 8, the third heat dissipation opening 434 is a strip-shaped through hole extending in the horizontal direction. The second water blocking portion 435 includes a plurality of water blocking ribs 4351, and the plurality of water blocking ribs 4351 are parallel to each other, and arranged at intervals along a length direction of the third heat dissipation opening 434. Each of the plurality of water blocking ribs 4351 is welded and fixed to an upper edge and a lower edge of the third heat dissipation opening 434, and has a preset angle α with a plane where the third heat dissipation opening 434 is located. In this way, an impact strength of rainwater on the second water blocking portion 435 may be reduced, and a waterproof effect of the second water blocking portion 435 may be improved without affecting the heat dissipation of the inductor 410.
In some embodiments, a degree of the preset angle α between the water blocking rib 4351 and the plane where the third heat dissipation opening 434 is located is any value in a range of 30° to 60° inclusive. For example, the degree of the preset angle α may be set as 30°, 40°, 45°, 55°, or 60°.
It can be understood that, in a case where the degree of the preset angle α is large (e.g., greater than 60° and less than 90°), the heat dissipation performance of the inductor assembly 400 may be improved, but the rainproof performance of the inductor assembly 400 may be reduced. In a case where the degree of the preset angle α is small (e.g., less than 30°, the water blocking ribs 4351 may shield the third heat dissipation opening 434 well, but the heat dissipation performance of the inductor assembly 400 may be reduced. Therefore, in the present disclosure, the degree of the preset angle α is set as any value in the range of 30° to 60° inclusive, so that the inductor assembly 400 may have both good heat dissipation performance and good waterproof performance.
FIG. 9 is a sectional view of an inductor assembly, in accordance with some embodiments. FIG. 10 is a partial enlarged view of the circle A in FIG. 9.
In some embodiments, as shown in FIGS. 9 and 10, there is a gap F between the shell side plate 421 and the cover side plate 432. In this way, in a case where the rainwater enters the inductor box cover 430 through the third heat dissipation opening 434, the rainwater is discharged from the inductor box cover 430 through the gap F due to gravity, which is conducive to improving the waterproof performance of the inductor assembly 400.
In some embodiments, as shown in FIGS. 8 to 10, the inductor box cover 430 further includes a third water blocking portion 436. The third water blocking portion 436 is disposed on an inner surface (i.e., a lower surface) of the cover top plate 431, and is located between the second heat dissipation opening 426 and the third heat dissipation opening 434. A height of the third water blocking portion 436 is greater than that of the second water blocking portion 435, and the third water blocking portion 436 is closer to the second heat dissipation opening 426 than the second water blocking portion 435.
For example, referring to FIG. 8, the third water blocking portion 436 may be configured as an annular. An upper end in an axial direction of the third water blocking portion 436 is connected to the cover top plate 431, and a lower end in the axial direction of the third water blocking portion 436 extends downward to exceed a horizontal plane where the second heat dissipation opening 426 is located. An orthogonal projection of the third water blocking portion 436 on the horizontal plane where the second heat dissipation opening 426 is located is a rectangular ring, and the second heat dissipation opening 426 on the horizontal plane where the second heat dissipation opening 426 is located is within the rectangular ring. In this way, when the rainwater enters the inductor box cover 430 through the third heat dissipation opening 434, the rainwater is blocked by the third water blocking portion 436 and fall on the shell top plate 423, and is discharged from the gap F due to gravity. Therefore, the rainproof capability of the inductor assembly 400 may be improved.
In some embodiments, as shown in FIGS. 7 and 9, the inductor box shell 420 further includes a fourth water blocking portion 428. The fourth water blocking portion 428 surrounds the second heat dissipation opening 426 and extends upward. At least a part of the fourth water blocking portion 428 extends to an inner side of the third water blocking portion 436. That is, with reference to the horizontal plane where the second heat dissipation opening 426 is located, a distance between an upper end of the fourth water blocking portion 428 and the reference plane is greater than a distance between the lower end of the third water blocking portion 436 and the reference plane. In this way, the rainwater entering the inductor box cover 430 from the third heat dissipation opening 434 may be effectively prevented from entering the inductor box shell 420 through the second heat dissipation opening 426, so that an operating stability of the inductor assembly 400 in rainy days may be improved.
In some embodiments, as shown in FIGS. 7 and 9, the inductor box shell 420 further includes a waterproof boss 429. The shell top plate 423 protrudes upward at a position proximate to the second heat dissipation opening 426, so as to form the waterproof boss 429. An upper end of the waterproof boss 429 is connected to a lower end of the fourth water blocking portion 428, and a size of the upper end of the waterproof boss 429 is smaller than that of the lower end of the waterproof boss 429. In this way, the rainwater entering the inductor box cover 430 from the third heat dissipation opening 434 may flow to the gap F along the waterproof boss 429, and be discharged from the inductor assembly 400 through the gap F.
It can be understood that, a shape of the waterproof boss 429 matches that of the second heat dissipation opening 426. For example, if the second heat dissipation opening 426 is in a shape of a circle, the waterproof boss 429 is substantially in a shape of a hollow frustum of a cone. An inner diameter of a ring enclosed by an upper end of the hollow truncated cone is smaller than that of a ring enclosed by a lower end of the hollow truncated cone. Alternatively, if the second heat dissipation opening 426 is in a shape of a rectangle, the waterproof boss 429 is substantially a hollow frustum of a pyramid. Length and width of a rectangular ring formed by an upper end of the hollow square frustum are respectively smaller than that of a rectangular ring formed by a lower end of the hollow square frustum.
In some embodiments, as shown in FIGS. 9 and 11, the inductor box base 440 further includes a first air inlet 444, a second air inlet 445 and an air inlet groove 446. The air outside the inductor box base 440 may enter the inductor box base 440 through the first air inlet 444, the second air inlet 445 and the air inlet groove 446, carry the heat dissipated by the inductor 410, and be discharged from the inductor assembly 400 through the first heat dissipation opening 425 or the third heat dissipation opening 434, thereby achieving heat dissipation of the inductor 410.
For example, the first air inlet 444 is disposed on the base body 441 and located below the inductor 410. The second air inlet 445 is disposed on a side plate of the base body 441. The base body 441 is recessed downward (as shown in FIG. 9), so as to form an air inlet groove 446. One end of the air inlet groove 446 is communicated with an outer space of the inductor assembly 400, and another end of the air inlet groove 446 is communicated with the first air inlet 444. In this way, airflow may enter the inductor assembly 400 through the first air inlet 444 and the second air inlet 445, so as to take away the heat generated by the inductor 410 from different orientations.
For example, airflow may enter the inductor assembly 400 from the first air inlet 444, so as to cool the inductor 410 from an underside of the inductor 410. Alternatively, airflow may enter the inductor assembly 400 from the second air inlet 445, so as to cool the inductor 410 from a side of the inductor 410.
As shown in FIG. 11, the inductor box base 440 includes two first air inlets 444, four second air inlets 445 and two air inlet grooves 446.

The limiting rib 437 is in a shape of a rectangular ring, and an outer contour of a lower end of the terminal block 450 matches an inner contour of the limiting rib 437. That is, the terminal block 450 is embedded in the limiting rib 437, so that the terminal block 450 and the inductor box cover 430 may be fixed.
The first connecting column 438 extends upward from the upper surface of the cover top plate 431 and located inside the limiting rib 437. The first connecting column 438 is a hollow cylinder with internal threads on its inner surface. The terminal block 450 includes a sixth connecting hole 451 whose position is corresponding to a position of the first connecting column 438. A fastener is inserted through the sixth connecting hole 451 and connected to the first connecting column 438, so as to achieve the fixed connection between the terminal block 450 and the inductor box cover 430.
In some embodiments, referring to FIGS. 5, 6 and 9, the inductor assembly 400 further includes an outer cover 460. The outer cover 460 is substantially in a shape of a hollow cuboid, and a side of the outer cover 460 facing the inductor box cover 430 is open. The outer cover 460 is fixedly connected to the inductor box cover 430, and covers the terminal block 450. In this way, the terminal block 450 may be prevented from being wetted by rainwater.
For example, referring to FIGS. 5 and 6, the outer cover 460 includes a second connecting portion 461. The second connecting portion 461 is disposed on a side plate of the outer cover 460, and extends from the side plate of the outer cover 460 in a direction away from the outer cover 460. The second connection portion 461 includes a seventh connecting hole 4611. The seventh connecting hole 4611 penetrates through the second connecting portion 461 along a thickness direction (i.e., the up-down direction) thereof. In some embodiments, the inductor box cover 430 further includes a second connecting column 439. The second connecting column 439 extends upward from the upper surface of the cover top plate 431 and a position of the second connecting column 439 corresponds to a position of the seventh connecting hole 4611. The second connecting column 439 is a hollow cylinder with internal threads on its inner surface. A fastener is inserted through the seventh connecting hole 4611 and connected to the second connecting column 439, so that the outer cover 460 and the inductor box cover 430 may be fixedly connected to each other.
In some embodiments, as shown in FIGS. 5 and 6, the inductor assembly 400 further includes a wire clip 401. The wire clip 401 is disposed on the inductor box cover 430 or the outer cover 460.
For example, referring to FIG. 6, the inductor assembly 400 includes a plurality of wire clips 401, a first wire clip 401A of the plurality of wire clips 401 is disposed on the cover side plate 432, a second wire clip 401B of the plurality of wire clips 401 is disposed on the side plate of the outer cover 460, and a third wire clip 401C of the plurality of wire clips 401 is provided on a top plate of the outer cover 460.
It can be understood that, power wires and signal wires of the inductor assembly 400 may be fixed by winding on the plurality of wire clips 401, so that the power wires and the signal wires may be prevented from being damaged by external force, and wiring of the inductor assembly 400 may be made orderly.
In some embodiments, the inductor box cover 430 and the outer cover 460 are both plastic members, so that the inductor 410 and terminals in the terminal block 450 may be insulated. For example, the inductor box cover 430 and the outer cover 460 are made of ABS, so as to have the good insulation performance and the good fire resistance.

A density of the sound insulating member 140 is greater than that of the indoor air duct component 110.
It can be understood that, when the air conditioner 1 is operating, the second fan 530 generates noise, and the noise is prone to transmit to the indoor through the indoor air duct component 110. Therefore, by providing the sound insulating member 140 on the first plate 111 with the density greater than that of the indoor air duct component 110, the noise generated by the second fan 530 during rotation may be blocked, which is conducive to improving experience of the user.

It will be noted that, an orthogonal projection of the filter mesh 154 and the two second baffles 155 on the first baffle 151 is a first orthogonal projection, an orthogonal projection of the fresh air duct outlet 1133 on the first baffle 151 is a second orthogonal projection, and the first orthogonal projection substantially coincides with the second orthogonal projection.
In the case where the fresh air duct 113 is opened, the fresh air may enter the indoor through the filter mesh 154, while the insects and other impurities in the fresh air duct 113 may be blocked by the filter mesh 154 and the second baffles 155, so as to improve the experience of the user.
In some embodiments, as shown in FIGS. 22 and 23, the fresh air member 150 further includes two guide ribs 156. The two guide ribs 156 are respectively connected to the two side plates 153 and respectively extend away from the bottom plate 152 along surfaces of the two side plates 153 away from the bottom plate 152. A front end of each guide rib 156 is connected to the first baffle 151, and a rear end of each guide rib 156 is connected to the second baffle 155. The two guide ribs 156 abut against left and right plates of the fresh air duct 113 respectively.
It can be understood that, if the side plates 153 directly abut against the left and right plates of the fresh air duct 113, a large friction needs to be overcome, so as to make the fresh air member 150 slide. Therefore, the friction generated when the fresh air member 150 slides in the fresh air duct 113 may be reduced, and sliding smoothness of the fresh air member 150 may be improved by reserving a gap between the side plates 153 and the fresh air duct 113, and providing the guide ribs 156 on the side plates 153 to abut against the left and right plates of the fresh air duct 113. In addition, the guide ribs 156 may further serve as reinforcing ribs, so as to improve a structural strength of the fresh air member 150.
In some embodiments, as shown in FIG. 23, the fresh air member 150 further includes an air passing cavity 157. The first baffle 151, the bottom plate 152, the two side plates 153 and the filter mesh 154 jointly define the air passing cavity 157. In this way, in a case where the fresh air duct 113 is not fully opened, that is, in a case where the first baffle 151 does not abut against a periphery of the fresh air duct outlet 1133, and the second baffles 155 is located in the fresh air duct 113, the fresh air may enter the indoor through the air passing cavity 157 and the air outlet 114 after filtering by the filter mesh 154.
In some embodiments, as shown in FIGS. 19 and 22, the fresh air member 150 further includes a pulling rod 158. One end of the pulling rod 158 is connected to the first baffle 151, and another end of the pulling rod 158 extends forward from the front surface of the first baffle 151. The air outlet 114 may be opened or closed through pulling or pushing the pulling rod 158.
FIG. 18A is a perspective view of an indoor unit with a part of an indoor air duct component removed, in accordance with some embodiments. FIG. 18B is a partial enlarged view of the circle W in FIG. 18A. FIG. 24 is a partial enlarged view of the circle G2 in FIG. 22.
In some embodiments, as shown in FIGS. 18A, 18B, 22 and 24, the pulling rod 158 includes a blocking notch 1581. In a width direction (i.e., the left-right direction) of the pulling rod 158, a side of the pulling rod 158 is recessed inward, so as to form the blocking notch 1581. In some embodiments, the indoor air duct component 110 further includes a blocking portion 115. The blocking portion 115 is located on an inner side plate of the air outlet 114 and cooperates with the blocking notch 1581. In a case where the blocking portion 115 is engaged with the blocking notch 1581, the fresh air member 150 may be limited, so that the fresh air duct 113 is opened or closed.
For example, a position of the blocking portion 115 may be set such that in a case where the fresh air member 150 slides to a position that the blocking portion 115 is engaged with the blocking notch 1581, the fresh air duct 113 is closed or opened.
It will be noted that, the blocking notch 1581 is an arc-shaped notch, and the blocking portion 115 is a cylindrical structural member. Therefore, the blocking notch 1581 may be disengaged from the blocking portion 115 by applying a certain force to the pulling rod 158. That is, the fresh air member 150 is released in the front-rear direction.
In some embodiments, as shown in FIG. 24, the pulling rod 158 includes a plurality of blocking notches 1581. A plurality of blocking openings 1581 are arranged at intervals along a length direction of the pulling rod 158. In this way, the blocking portion 115 may be engaged with either of the plurality of blocking notches 1581, so that the fresh air duct 113 is opened to different degrees.
In some embodiments, as shown in FIGS. 18B and 22, the indoor air duct component 110 further includes a guide portion 116. The guide portion 116 is disposed in the air outlet 114 and a position of the guide portion 116 corresponds to a position of the pulling rod 158. The guide portion 116 is configured to guide and limit the pulling rod 158, so that the fresh air member 150 slides in the front-rear direction due to the guidance of the guide portion 116.
For example, referring to FIG. 18B, the guide portion 116 includes two guide buckles 1161 arranged opposite and spaced apart. The two guide buckles 1161 are respectively engaged with left and right sides of the pulling rod 158, so as to limit the pulling rod 158 in the left-right direction.
In some embodiments, as shown in FIGS. 17B, 18B and 22, the pulling rod 158 further includes two guide grooves 1582. The two guide grooves 1582 are respectively located on two sides of the pulling rod 158 and extend in a sliding direction of the pulling rod 158. Both of the two guide grooves 1582 penetrate through a rod body of the pulling rod 158 along a thickness direction thereof, and extend along a length direction of the pulling rod 158. In some embodiments, the two guide buckles 1161 are respectively engaged with groove bottoms of the two guide grooves 1582, so as to limit the pulling rod 158 in the left-right direction. The blocking notch 1581 may be disposed at a groove bottom of either of the two guide grooves 1582.
<Indoor Heat Exchanger>
In some embodiments, the indoor unit 100 further includes an indoor heat exchanger. The indoor heat exchanger is configured to make the indoor air exchange heat with the refrigerant conveyed in the indoor heat exchanger. For example, the indoor heat exchanger is used as an evaporator in a case where the air conditioner 1 is operating in a cooling mode, and in this case, the refrigerant is evaporated by absorbing heat in the indoor air through the indoor heat exchanger. The indoor heat exchanger is used as a condenser in a case where the air conditioner 1 is operating in a heating mode, and in this case, the refrigerant is condensed by dissipating heat into the indoor air through the indoor heat exchanger.
It can be understood that, in a case where the indoor heat exchanger is used as the evaporator, a temperature of the refrigerant in the indoor heat exchanger is low. Therefore, water vapor in the air is easily condensed on an outer surface of the indoor heat exchanger and forms droplets. The droplets fall downward due to gravity and collect as condensed water.
<Drainage Assembly>
FIG. 25 is yet another perspective view of a main body, in accordance with some embodiments. FIG. 26 is a perspective view of an air conditioner body with an outdoor unit removed, in accordance with some embodiments. FIG. 27 is a partial enlarged view of the circle H in FIG. 26.
In some embodiments, as shown in FIGS. 25 and 26, the main body 101 further includes a drainage assembly 600. The drainage assembly 600 is configured to collect the condensed water generated by the indoor heat exchanger, and discharge the condensed water to the outdoor unit 200 due to gravity. In some embodiments, as shown in FIGS. 25 to 27, the drainage assembly 600 includes a drain pan 610, a drainage channel 620 and a water tank 630.
The drain pan 610 is disposed on the base 300 and is located on the front side of the indoor air duct component 110. The indoor heat exchanger is installed on the drain pan 610. A portion of a bottom plate of the base 300 extends downward, so as to form the water tank 630 that opens upward. The water tank 630 is located on the rear side of the indoor air duct component 110 and is located on the outdoor side of the air conditioner 1 (the outdoor side including the part of the air conditioner 1 located outdoors).
The drainage channel 620 is disposed in the indoor air duct component 110 and penetrates through the indoor air duct component 110 in an arrangement direction (i.e., the front-rear direction) of the indoor air duct component 110 and the outdoor air duct component 210. One end of the drainage channel 620 is connected to the drain pan 610, and another end of the drainage channel 620 is located at an upper portion of the water tank 630. In this way, the condensed water collected in the drain pan 610 may flow into the drainage channel 620 due to gravity. The condensed water in the drainage channel 620 may flow into the water tank 630 due to gravity.
It can be understood that, if the low-temperature condensed water directly collects on the base 300 and flows to the outdoor side through the drainage channel 620 on the base 300, a temperature of the base 300 decreases, and the water vapor in the indoor air is prone to condense on the outer surface of the base 300. Droplets condensed on the outer surface of the base 300 may drip into the housing 10, causing water to accumulate in the housing 10, and even causing a short circuit, which has a certain safety hazard. Therefore, by providing the drain assembly 600 in the main body 101, the condensed water generated by the indoor heat exchanger may be directly discharged to the water tank 630 located at the outdoor side, so that condensation on the outer surface of the base 300 may be avoided, which is conducive to improving the operation reliability of the air conditioner 1.
In some embodiments, as shown in FIGS. 26 and 27, the drainage assembly 600 further includes a water guiding member 640. One end of the water guiding member 640 corresponds to the another end of the drainage channel 620, and is connected to the rear side plate of the indoor air duct component 110. Another end of the water guiding member 640 extends downward and backward into the water tank 630. A water guiding channel 641 is defined in the water guiding member 640, one end of the water guiding channel 641 is communicated with the another end of the drainage channel 620, and another end of the water guiding channel 641 is communicated with the water tank 630.
During the operation of the air conditioner 1, the condensed water generated by the indoor heat exchanger may be collected into the water tank 630 located on the outdoor side through the drain pan 610, the drainage channel 620 and the water guiding channel 641 in sequence, so that condensation on the outer surface of the base 300 may be avoided, which is conducive to improving the operation reliability of the air conditioner 1.
In some embodiments, as shown in FIGS. 26 and 27, the water guiding member 640 includes a bottom plate 642 (which is called a water guiding member bottom plate 642) and two side plates 643 (which is called two water guiding member side plates 643) respectively disposed on both sides of the water guiding member bottom plate 642. The water guiding member bottom plate 642 and the two water guiding member side plates 643 jointly define the water guide channel 641. The two water guiding member side plates 643 extend upward from two sides of the water guiding member bottom plate 642 respectively, and are configured to block the condensed water, so that the condensed water flows into the water tank 630 through the water guiding channel 641.
FIG. 28 is yet another perspective view of a main body, in accordance with some embodiments.
In some embodiments, as shown in FIGS. 27 and 28, the water guiding member 640 further includes two second reinforcing ribs 644. The two second reinforcing ribs 644 are respectively disposed on the two water guiding member side plates 643, and are connected to the indoor air duct component 110, so that the structural strength of the water guiding member 640 may be improved.
FIG. 29 is another exploded view of a main body, in accordance with some embodiments. FIG. 30 is a structural diagram of a base, in accordance with some embodiments.
In some embodiments, as shown in FIGS. 29 and 30, the base 300 includes a first groove 301 and a second groove 302. The first groove 301 is configured to install the compressor 1011, the inductor assembly 400 and other components. The second groove 302 is configured to install the indoor air duct component 110, the outdoor air duct component 210, the indoor heat exchanger, the drainage assembly 600 and other components.
In some embodiments, as shown in FIG. 30, the second groove 302 includes a barrier rib 310 and a second mounting groove 320. The barrier rib 310 is located in the middle of the second groove 302 along the front-rear direction, and extends from a left side plate of the second groove 302 to a right side plate of the second groove 302, so that the second groove 302 is divided into the second mounting groove 320 and the water tank 630.
The second mounting groove 320 is located on a front side of the barrier rib 310, and the water tank 630 is located on a rear side of the barrier rib 310. The drain pan 610 is disposed in the second mounting groove 320. The water guiding member 640 is disposed on the barrier rib 310, so that the water guiding member 640 is spaced apart from a groove bottom of the water tank 630 by a certain distance. In this way, rainwater or condensed water in the outdoor side may be prevented from flowing into the indoor side through the water guiding member 640.
In some embodiments, in the height direction of the air conditioner 1, a groove bottom of the second mounting groove 320 is higher than that of the water tank 630, so as to prevent rainwater or condensed water in the outdoor side from flowing into the indoor side (including the part of the air conditioner 1 located indoors).
In some embodiments, as shown in FIG. 30, the base 300 further includes a positioning groove 330. A part of an upper surface of the barrier rib 310 is recessed downward, so as to form the positioning groove 330. An extending direction of the positioning groove 330 is same as that of the barrier rib 310. In some embodiments, referring to FIGS. 27 and 29, the indoor air duct component 110 further includes a second positioning portion 117, and the outdoor air duct component 210 further includes a third positioning portion 211. The second positioning portion 117 is engaged with the positioning groove 330, so that the indoor air duct component 110 is positioned on the base 300. The third positioning portion 211 is engaged with the positioning groove 330 so that the outdoor air duct component 210 is positioned on the base 300. In this way, assembly efficiency of the air conditioner 1 may be improved.
In some embodiments, the drain pan 610, the water guiding member 640 and the indoor air duct component 110 are integrally formed, so that the assembly process may be simplified and the assembly efficiency of the air conditioner 1 may be improved.
