[0002] When the indoor unit of the air conditioner is in cooling mode, the temperature of the evaporator is significantly lower than the ambient temperature due to the low-temperature refrigerant flowing inside. After the air flow inhaled by the indoor unit of the air conditioner flows through the evaporator, while the heat is absorbed by the evaporator and the temperature is reduced, the moisture contained in it will also condense on the surface of the evaporator when it encounters cold and form condensed water.

[0003] In order to prevent condensed water from polluting the indoor unit of the air conditioner, the existing indoor unit of the air conditioner usually has a water tank at the bottom of the evaporator to collect the condensed water, and uses a drain pipe connected to the water tank to drain the condensed water out of the indoor unit of the air conditioner. However, the connection position between the drain pipe of the existing indoor unit of the air conditioner and the water tank is fixed, and in some cases the drain pipe may need to be bent during layout.

[0040] Figure 1 is a schematic exploded view of an air conditioner indoor unit 20 according to an embodiment of the utility model; Figure 2 yes Figure 1 A schematic diagram of the air duct component 30 of the indoor unit 20 of the air conditioner is shown.

[0041] The present embodiment provides an air conditioner indoor unit 20, which includes an evaporator 27, a water receiving tank 31, a movable connector 41, and a drain pipe 42. The water receiving tank 31 is arranged below the bottom end of the evaporator 27, and is used to receive condensed water from the evaporator 27. A first drain connector 313 is formed on the water receiving tank 31; a first drain hole 313A connected to the water receiving tank 31 is formed on the first drain connector 313, and is used to drain the condensed water in the water receiving tank 31. The movable connector 41 is arranged on the first drain connector 313 so as to be rotatable forward and backward, and is used to receive the condensed water discharged from the first drain hole 313A. The drain pipe 42 is connected to the movable connector 41, and is used to discharge the condensed water in the movable connector 41 out of the air conditioner indoor unit 20.

[0042] refer to Figure 1 As shown, the indoor unit 20 of the air conditioner of this embodiment generally includes a housing 21 having a front opening and a front panel 22 arranged at the front opening. The housing 21 is provided with an air supply fan 25, an evaporator 27, and an air duct member 30 for fixing the air supply fan 25 and forming an air supply duct. Figure 2As shown, the water receiving groove 31 is a part of the air duct component 30, and the air duct component 30 also includes a fan bracket 32 ​​for fixing the air supply fan 25. The two-part fan bracket 32 ​​located at both ends of the air supply fan 25 can be integrally formed with the water receiving groove 31, and integrally formed with other parts of the air duct component 30, such as part or all of the air duct sidewalls of the air supply air duct.

[0043] The air duct component 30 may further include a first fan fixing member 33 and a second fan fixing member 34 located at both ends of the air supply fan 25 and cooperating with the fan bracket 32 ​​to fix the air supply fan 25, wherein the first fan fixing member 33 is located on one side where a driving motor 26 for driving the air supply fan 25 is provided, and is used to fix the driving motor 26 in cooperation with the fan bracket 32. The first fan fixing member 33 and the second fan fixing member 34 are also fixed to both ends of the evaporator 27 to support and fix the evaporator 27. At the same time, the bottom end of the evaporator 27 can extend into the water receiving tank 31, so that the water receiving tank 31 also supports and fixes the evaporator 27.

[0044] When the air conditioner indoor unit 20 is in cooling mode, the temperature of the evaporator 27 is significantly lower than the ambient temperature due to the low-temperature refrigerant flowing inside. After the air flow sucked by the air conditioner indoor unit 20 flows through the evaporator 27, while the heat is absorbed by the evaporator 27 and the temperature is reduced, the water contained in the air flow will also condense on the surface of the evaporator 27 when it encounters cold and forms condensed water. The condensed water flows downward along the fin surface of the evaporator 27 and falls into the water receiving tank 31 located below the bottom end of the evaporator 27. The condensed water in the water receiving tank 31 can be discharged from the first drainage hole 313A on the first drainage connector 313 to the movable connector 41, and then discharged from the air conditioner indoor unit 20 through the drainage pipe 42 connected to the movable connector 41.

[0045] The existing air conditioner indoor unit directly connects the drain connector of the water tank to the drain pipe. In order not to affect the aesthetics of the air conditioner indoor unit, the drain pipe usually bends and extends backward, downward or laterally, but does not bend and extend forward. Since the connection position is fixed, for different installation scenarios of the air conditioner indoor unit, the drain pipe may need to bend in different directions and extend out of the indoor unit, and may need to bend in both the horizontal and vertical directions. Although the drain pipe is a hose and can be bent, if the bending angle of a certain section is large, the drain pipe is easy to collapse at this position, causing blockage inside the drain pipe, seriously affecting the drainage effect.

[0046] The air conditioner indoor unit 20 of this embodiment is provided with a movable connector 41 that can rotate forward and backward on the first drainage connector 313, and the drain pipe 42 is connected to the movable connector 41, so that the connection angle of the drain pipe 42 relative to the first drainage connector 313 of the water tank 31 can be adjusted within a certain range. Under the rotation cooperation of the movable connector 41, the bending angle required by the drain pipe 42 itself is smaller. Therefore, when the air conditioner indoor unit 20 of this embodiment is installed, no matter which direction the drain pipe 42 needs to be bent, the setting of the movable connector 41 can prevent the drain pipe 42 from being easily folded. In the case where the drain pipe 42 is bent downward and extends from the bottom of the air conditioner indoor unit 20, the movable connector 41 has the most obvious effect of preventing the drain pipe 42 from being folded, and can make the drain pipe 42 between the movable connector 41 and the extension position basically not bend.

[0047] The air inlet of the indoor unit 20 of the air conditioner of this embodiment can be opened on the front panel 22, and the opening and closing of the air inlet can be controlled by the air inlet baffle 23 rotatably arranged on the front panel 22. At the same time, the air outlet can also be opened on the front panel 22, but in order to facilitate the removal of the front panel 22, the air outlet baffle 24 can be rotatably arranged at the outlet of the air supply duct defined by the duct member 30.

[0048] Figure 3 yes Figure 1 A schematic diagram of the movable connector 41 of the indoor unit 20 of the air conditioner is shown; Figure 4 yes Figure 1 A schematic partial cross-sectional view of the air conditioner indoor unit 20 is shown; Figure 5 yes Figure 1 Another schematic partial cross-sectional view of the air conditioner indoor unit 20 is shown.

[0049] In some optional embodiments, the movable joint 41 defines a receiving cavity 41A with an upward opening, and the movable joint 41 is configured to have a first position in which the receiving cavity 41A opens upward, and a second position in which the receiving cavity 41A opens forward to the greatest extent; the movable joint 41 is also configured to be able to rotate arbitrarily between the first position and the second position. When the movable joint 41 rotates to any position, the lowest point of the outlet end of the first drainage hole 313A is located in the receiving cavity 41A.

[0050] Figure 4 and Figure 5The partial cross-sectional views of the air conditioner indoor unit 20 at the movable joint 41 when the movable joint 41 is located in the first position and the second position are illustrated respectively. The second position in which the opening of the accommodating chamber 41A is maximally oriented to the front refers to the position in which the movable joint 41 cannot be further rotated to make the opening of the accommodating chamber 41A more oriented to the front. In order to ensure that the condensed water entering the accommodating chamber 41A can be discharged smoothly, the opening of the accommodating chamber 41A needs to be maintained at an oblique upward angle, so the rotation range of the movable joint 41 needs to be limited accordingly. In some optional embodiments, the position of the movable joint 41 can be located just below the partial structure of the air duct component 30, and the air duct component 30 prevents the movable joint 41 from continuing to rotate after rotating to the second position.

[0051] The movable connector 41 can be rotated arbitrarily between the first position and the second position. Therefore, no matter how the drain pipe 42 needs to be bent during the installation of the air conditioner indoor unit 20, the movable connector 41 can rotate to a suitable position by itself, and because the rotation position will not exceed the second position, the movable connector 41 will not flip over to the accommodating chamber 41A with the opening facing downward due to the change in the position of the drain pipe 42, causing the movable connector 41 to lose its function of receiving condensed water.

[0052] In addition, refer to Figure 4 and Figure 5 As shown, when the movable connector 41 of this embodiment is rotated to any position, the lowest point of the outlet end of the first drainage hole 313A is located in the accommodating cavity 41A, so the water discharged from the first drainage hole 313A can directly enter the accommodating cavity 41A and is not easily splashed to the outside of the movable connector 41.

[0053] The outlet end of the first drain hole 313A refers to the end of the first drain hole 313A away from the water receiving tank 31, and the condensed water leaves the water receiving tank 31 from the outlet end of the first drain hole 313A. Correspondingly, the inlet end of the first drain hole 313A refers to the end of the first drain hole 313A connected to the inside of the water receiving tank 31, and the condensed water enters the first drain hole 313A from the inlet end of the first drain hole 313A.

[0054] In some optional embodiments, a second drainage connector 411 is formed on the movable connector 41, and the drainage pipe 42 is connected to the second drainage connector 411; the second drainage connector 411 is provided with a second drainage hole 41B connected to the accommodating chamber 41A, which is used to drain the condensed water in the movable connector 41 to the drainage pipe 42. The movable connector 41 is configured such that when the movable connector 41 is in the second position, the lowest point of the inlet end of the second drainage hole 41B is lower than the lowest point of the opening of the accommodating chamber 41A.

[0055] The movable joint 41 of this embodiment is connected to the drain pipe 42 through the second drain joint 411 formed thereon, and the condensed water from the water receiving tank 31 is discharged to the drain pipe 42 through the second drain hole 41B opened on the second drain joint 411. The second drain joint 411 is usually connected to the drain pipe 42 by being inserted into the drain pipe 42 to avoid water leakage at the connection.

[0056] In order to prevent the movable joint 41 from rotating too much, causing the condensed water to flow out from the opening of the accommodating chamber 41A instead of all flowing out from the second drainage hole 41B, the present embodiment also sets the shape and rotation range of the movable joint 41, and makes it possible for the lowest point of the inlet end of the second drainage hole 41B to be lower than the lowest point of the opening of the accommodating chamber 41A when the movable joint 41 is in the second position, so that even if the movable joint 41 is rotated to the highest position, the condensed water still flows out from the second drainage hole 41B preferentially.

[0057] In some optional embodiments, the first drainage connector 313 is formed to extend downward and backward in an inclined manner.

[0058] In order to make the rotation range of the movable connecting head 41 more convenient for the installation of the drain pipe 42, the first drain connecting head 313 of the present embodiment is formed by extending backward and downward from the surface of the water receiving trough 31, rather than extending vertically downward or in other directions, so that the movable connecting head 41 can rotate backward at a larger angle without being interfered by the shape of the water receiving trough 31 itself.

[0059] In some optional embodiments, the movable connector 41 forms a connecting ear 412 on both lateral sides of the opening of the accommodating cavity 41A, and the connecting ear 412 is rotatably connected to the first drainage connector. When the movable connector 41 is in the first position, the opening height of the accommodating cavity 41A behind the connecting ear 412 is higher than that of the front side.

[0060] refer to Figure 3 As shown, a connection shaft may be formed on the connection ear 412 of the movable connector 41 of this embodiment, and inserted into the opening of the side wall of the first drainage connector 313, so that the movable connector 41 can rotate around the connection shaft on the first drainage connector 313. Of course, in other embodiments, a connection shaft may be formed on the side wall of the first drainage connector 313, and inserted into the opening of the connection ear 412, so that the movable connector 41 can rotate around the connection shaft on the first drainage connector 313.

[0061] refer to Figure 3 and Figure 4As shown, when the movable connector 41 of this embodiment is in the first position, the opening height of the accommodating chamber 41A on the rear side of the connecting ear 412 is higher than that on the front side. When the movable connector 41 is in the second position, its rear end is usually required to abut against the air duct component 30 to prevent further rotation. The opening height of the accommodating chamber 41A on the rear side of the connecting ear 412 is higher than that on the front side, which can make the rear end of the movable connector 41 abut against the air duct component 30 earlier, and avoid the opening of the accommodating chamber 41A in the second position being too toward the front side, so that condensed water can easily leak out. At the same time, when the first drainage connector 313 extends backward and downward, the opening height of the accommodating chamber 41A on the rear side of the connecting ear 412 is higher than that on the front side, which can also increase the depth of the first drainage hole 313A extending into the accommodating chamber 41A, further preventing condensed water from splashing to the outside of the movable connector 41.

[0062] Figure 6 yes Figure 1 Another schematic diagram of the air duct component 30 of the indoor unit 20 of the air conditioner is shown; Figure 7 yes Figure 1 A schematic partial cross-sectional view of the air duct component 30 of the indoor unit 20 of the air conditioner is shown; Figure 8 yes Figure 1 Another schematic partial cross-sectional view of the air duct member 30 of the air conditioner indoor unit 20; Fig. 9 yes Figure 1 Another schematic partial cross-sectional view of the air duct member 30 of the indoor unit 20 of the air conditioner is shown.

[0063] Figure 6 3 is a top view of the air duct component 30 with a certain inclination angle, and the viewing angle is directly connected to the bottom surface of the water tank 31, so that the water receiving part 311 and the confluence part 312 of the water tank 31 are simultaneously illustrated. In order to more clearly illustrate the specific position of the air duct component 30, Figure 6 The partial structure of the transverse middle portion of the air duct component 30 is omitted by the break line. Figure 7 , Figure 8 and Fig. 9 They are partial cross-sectional schematic diagrams of the air duct component 30 at the water receiving portion 311 , the first confluence section of the confluence portion 312 , and the second confluence section.

[0064] refer to Figure 6 As shown, in some optional embodiments, the water receiving tank 31 includes a water receiving portion 311 and a confluence portion 312. The water receiving portion 311 is located directly below the bottom end of the evaporator 27 and corresponds to the shape of the bottom end of the evaporator 27, and is used to receive condensed water from the evaporator 27. The confluence portion 312 is located at at least one end of the water receiving portion 311; the bottom surface height of the confluence portion 312 is lower than the bottom surface height of the water receiving portion 311, so that the condensed water in the water receiving portion 311 is gathered in the confluence portion 312. A first drainage connector 313 is formed at the confluence portion 312 to discharge the condensed water in the confluence portion 312.

[0065] exist Figure 1 In the illustrated embodiment, the evaporator 27 is disposed in the transverse direction, and the water receiving portion 311 extends in the transverse direction corresponding to the shape of the evaporator 27. The confluence portion 312 is disposed at least at one end of the water receiving portion 311, or two confluence portions 312 are disposed at both ends of the water receiving portion 311. The condensed water condensed on the evaporator 27 first falls into the water receiving portion 311, and then flows sideways to the confluence portion 312 with a lower height, thereby converging small streams of water so as to be discharged from the first drainage connector 313 formed at the confluence portion 312.

[0066] refer to Figure 7 As shown, in some optional embodiments, the bottom surface of the water receiving portion 311 has an inclined surface with a front end higher than a rear end.

[0067] The bottom surface of the water receiving portion 311 can be a flat surface, but in order to control the height of the bottom surface of the water receiving portion 311, the bottom surface of the water receiving portion 311 can also be composed of two flat surfaces, and one of the surfaces is an inclined surface with a front end higher than a rear end. The inclined surface can achieve a better confluence effect than a flat surface, so that the condensed water can converge to the confluence portion 312 faster and cleaner.

[0068] Support ribs for supporting and fixing the evaporator 27 may be formed in the water receiving portion 311 , and the bottom end of the evaporator 27 may be supported or clamped and fixed between the support ribs and a side wall of the water receiving portion 311 .

[0069] In some optional embodiments, the confluence portion 312 includes a first confluence section 3121 and a second confluence section 3122. The first confluence section 3121 is connected to the lateral end of the water receiving portion 311 and extends backwards, and is used to receive condensed water from the water receiving portion 311; the bottom surface of the first confluence section 3121 is an inclined surface with a front end higher than a rear end. The second confluence section 3122 is connected to the rear end of the first confluence section 3121 and extends horizontally, and is used to receive condensed water from the first confluence section 3121; the first drainage connector 313 is formed at the second confluence section 3122.

[0070] refer to Figure 6 , Figure 8 and Fig. 9 As shown, the first confluence section 3121 is connected to the lateral end of the water receiving portion 311 and extends backward, and the second confluence section 3122 is connected to the rear end of the first confluence section 3121 and extends laterally, so that the water receiving groove 31 can guide the condensed water to the side position of the air duct component 30, and the position is lower and further to the rear relative to the water receiving portion 311, so it is more convenient to connect the movable connecting head 41 and the drain pipe 42.

[0071] The water receiving portion 311, the first confluence section 3121 and the second confluence section 3122 respectively have an inclined bottom surface with a front end higher than a rear end. In some optional embodiments, their inclined bottom surfaces are located on the same plane, thereby making the water receiving portion 311, the first confluence section 3121 and the second confluence section 3122 transition smoothly.

[0072] refer to Fig. 9 As shown, in some optional embodiments, the first drainage connector 313 is formed on the rear side wall of the second confluence section 3122, and extends backward and downward from the rear side wall of the second confluence section 3122. The inlet of the first drainage hole 313A of this embodiment is opened on the rear side wall of the second confluence section 3122, and is close to the bottom surface of the second confluence section 3122, or can also be connected to the bottom surface of the second confluence section 3122.

[0073] Fig.10 1 is a schematic diagram of an air conditioner 10 according to an embodiment of the present invention.

[0074] The air conditioner 10 of this embodiment includes an air conditioner indoor unit 20, an air conditioner outdoor unit, and a refrigerant pipeline connecting the two.
