TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioning equipment, in particular to an air conditioner indoor unit and an air conditioner. BACKGROUND

[0002] For air conditioners with fresh air function, a layer of sponge is usually attached to the outer surface of the fresh air module to provide thermal insulation for the fresh air module, thereby avoiding condensate water from the fresh air module. However, attaching the sponge to the outer surface of the fresh air module requires manual operation, which is inefficient and time-consuming. Moreover, manual attachment of the sponge may result in incorrect positioning, which requires reattachment and greatly increases the time cost and labor cost, thereby reducing the production efficiency of the air conditioner. SUMMARY

[0003] The main purpose of the present application is to provide an air conditioner indoor unit, which aims to improve the production efficiency of the air conditioner indoor unit and increase the volume of the fresh air module to improve the air intake of the fresh air module.

[0004] To achieve the above-mentioned purpose, the air conditioner indoor unit provided by the present application comprises a shell, a fresh air module and a first water collecting groove. The fresh air module is arranged in the shell and located on one side of the shell along the length direction of the shell. The first water collecting groove is arranged below the fresh air module to collect condensate water on the fresh air module.

[0005] Optionally, the air conditioner indoor unit further comprises a heat exchanger and a second water collecting groove. The heat exchanger is arranged in the shell, and the fresh air module is arranged on one side of the heat exchanger. The second water collecting groove is located below the heat exchanger and communicates with the first water collecting groove.

[0006] Optionally, the first water collecting groove comprises a first sub-groove and a second sub-groove, and the second sub-groove communicates the first sub-groove with the second water collecting groove.

[0007] Optionally, the bottom surface of the first sub-groove is higher than the bottom surface of the second sub-groove, and a drain hole is arranged in the first water collecting groove.

[0008] Optionally, the side wall of the first sub-groove close to the second sub-groove is inclined from top to bottom towards the second sub-groove.

[0009] Optionally, the groove width of the first sub-groove along the width direction of the shell is greater than the groove width of the second sub-groove along the width direction of the shell.

[0010] Optionally, the front side wall of the first water collecting groove is higher than the front side wall of the second water collecting groove.

[0011] Optionally, the indoor unit of the air conditioner further includes a water baffle, which is installed above the front side wall of the first water receiving trough and is located close to the fresh air module.

[0012] Optionally, the housing includes a face frame, on which a water baffle corresponding to the fresh air module is provided, and the water baffle is located above the front side wall of the first water receiving tank.

[0013] Optionally, the housing includes a chassis, on which the first water receiving trough is formed.

[0014] Optionally, the bottom of the first sub-slot is provided with an installation port corresponding to the air inlet of the fresh air module, and the edge of the installation port extends toward the fresh air module to form a positioning part.

[0015] Optionally, the indoor unit of the air conditioner further includes a first rubber pad, which is located between the fresh air module and the bottom of the first sub-slot.

[0038] This invention proposes an embodiment of an air conditioner indoor unit, which is provided with a first water receiving tank for collecting condensate from the fresh air module. Therefore, after manually attaching a sponge to the outer surface of the fresh air module, the condensate generated on the outer surface of the fresh air module will drip directly into the first water receiving tank. Eliminating the step of manually attaching the sponge can greatly improve production efficiency. At the same time, the space freed up after not attaching the sponge can be used to further enlarge the fresh air module and increase its air volume.

[0039] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the indoor unit of the air conditioner includes a housing 10, a fresh air module 20, and a first water receiving tank 30. The fresh air module 20 is disposed inside the housing 10 and located on one side of the housing 10 along its length; the first water receiving tank 30 is disposed below the fresh air module 20 to collect condensate from the fresh air module 20.

[0040] Specifically, the housing 10 can be designed to be circular, or it can be square, prismatic, etc. In this embodiment, the housing 10 is approximately square. The housing 10 is made of a rigid material, which can be ABS, HIPS, PP, PC, or other rigid materials, or metal or alloy materials, etc., without specific limitations. The housing 10 of the air conditioner indoor unit includes a chassis 11 and a front frame. A cavity is formed between the chassis 11 and the front frame to accommodate the internal components of the air conditioner indoor unit (such as a fan, heat exchanger, fresh air module 20, etc.). The fresh air module 20 is installed inside the housing 10 and is located on one side of the housing 10 along its length. A first water receiving trough 30 is installed below the fresh air module 20. The first water receiving trough 30 can be directly formed from the chassis 11, or it can be set separately and installed separately below the fresh air module 20 during later assembly to collect the condensate generated by the fresh air module 20 during operation.

[0041] The technical solution of the present invention provides a first water receiving tank 30 below the fresh air module 20, allowing the condensate generated by the fresh air module 20 during operation to flow directly into the first water receiving tank 30. Compared with the fresh air module in a traditional air conditioner indoor unit, the fresh air module 20 in this air conditioner indoor unit does not require manual pasting of sponge on its surface, which can save manpower and improve the production efficiency of the air conditioner indoor unit. At the same time, the fresh air module 20 can be made larger, thereby increasing the air volume of the fresh air module 20 and reducing the noise generated by the fresh air module during operation.

[0042] Please see Figure 6 In one embodiment, the indoor unit of the air conditioner further includes a heat exchanger and a second water inlet 40. The heat exchanger is disposed inside the housing 10, the fresh air module 20 is disposed on one side of the heat exchanger, and the second water inlet 40 is located below the heat exchanger and is connected to the first water inlet 30.

[0043] Specifically, the heat exchanger is mounted on the chassis 11 and located on one side of the fresh air module 20. The second water receiving tank 40 extends along the length of the housing 10 and is located below the heat exchanger. The second water receiving tank is strip-shaped and is mainly used to collect the condensate generated by the heat exchanger during operation. The second water receiving tank 40 is connected to the first water receiving tank 30, so only one drain hole 311 needs to be provided, instead of separate drain holes 311 in the first water receiving tank 30 and the second water receiving tank 40.

[0044] Furthermore, the first water receiving trough 30 includes a first sub-trough 31 and a second sub-trough 32, with the second sub-trough 32 connecting the first sub-trough 31 and the second water receiving trough 40. Specifically, the fresh air module 20 is located above the first water receiving trough 30 and installed in the first sub-trough 31, while the second sub-trough 32 connects the first sub-trough 31 and the second water receiving trough 40. Simultaneously, the bottom surface of the first sub-trough 31 is higher than the bottom surface of the second sub-trough 32, and a drain hole 311 is provided within the first water receiving trough 30. The bottom surface of the second sub-trough 32 can be flush with the bottom surface of the second water receiving trough 40, or the bottom surface of the second sub-trough 32 can be lower than the bottom surface of the second water receiving trough 40. The drain hole 311 is specifically located in the second sub-slot 32. Since the bottom surface of the second sub-slot 32 is lower than that of the first sub-slot 31 and the second water receiving tank 40, the condensate generated by the fresh air module 20 will flow from the first sub-slot 31 to the second sub-slot 32 and be discharged through the drain hole 311. The condensate generated by the heat exchanger will flow from the second water receiving tank 40 to the second sub-slot 32 and finally be discharged through the drain hole 311.

[0045] Please see Figure 6 In one embodiment, the side wall of the first sub-slot 31 near the second sub-slot 32 is inclined downwards towards the second sub-slot 32. This arrangement serves as a guide, allowing condensate generated on the fresh air module 20 to flow directly into the second sub-slot 32 via the inclined surface, preventing water accumulation at the junction of the first and second sub-slots 31. Of course, in other embodiments, the side wall of the first sub-slot 31 near the second sub-slot 32 can also be vertically arranged; no specific limitation is made here.

[0046] Please see Figure 6 In one embodiment, the width of the first sub-slot 31 along the width direction of the housing 10 is greater than the width of the second sub-slot 32 along the width direction of the housing 10. Specifically, the first sub-slot 31 is generally rectangular in shape. The first sub-slot 31 is used to install the fresh air module 20, so the width of the first sub-slot 31 is wider. The width of the second sub-slot 32 is the same as the width of the second water receiving tank. This design facilitates mold manufacturing.

[0047] Please see Figure 1 , Figure 2 and Figure 6 In one embodiment, the front sidewall 34 of the first water receiving tank is higher than the front sidewall 41 of the second water receiving tank. Specifically, the front sidewall 34 of the first water receiving tank and the front sidewall 41 of the second water receiving tank are integrally formed. This arrangement can reduce the design of molds and the manufacturing steps of the front sidewall 34 and the front sidewall 41 of the first water receiving tank, effectively improving production efficiency.

[0048] The front sidewalls 34 and 41 of the first and second water receiving troughs are plate-shaped. These walls can be mounted on the chassis 11 or not. Their primary function is to prevent water from entering the system. When the fresh air module 20 generates condensate during operation, the condensate slides downwards from its outer surface under gravity, dripping onto the front sidewall 34 of the first water receiving trough and flowing into the first water receiving trough 30, eventually draining from the indoor unit through the drain hole 311. Similarly, when the heat exchanger generates condensate during operation, the condensate slides downwards from its outer surface under gravity, dripping onto the front sidewall 41 of the second water receiving trough and flowing into the second water receiving trough 40, eventually draining from the drain hole 311.

[0049] The front wall 34 of the first water collection tank is located below the fresh air module 20 and is used to collect condensate dripping from the fresh air module 20. The front wall 41 of the second water collection tank is located below the heat exchanger and is used to collect condensate dripping from the heat exchanger. Because the structural shapes of the fresh air module 20 and the heat exchanger are different, the position where the condensate dripping from the fresh air module 20 falls into the first water collection tank 30 is higher than the position where the condensate dripping from the heat exchanger falls into the second water collection tank 40. Therefore, the height of the front wall 34 of the first water collection tank should be higher than the height of the front wall 41 of the second water collection tank to prevent the condensate dripping from the fresh air module 20 from falling into the air duct or the casing 10 and affecting the use of the indoor unit of the air conditioner.

[0050] In another embodiment, the indoor unit of the air conditioner also includes a water baffle, which is installed above the wall of the first water receiving tank 30 and is located near the fresh air module 20.

[0051] Specifically, if the height of the front wall 34 of the first water receiving tank is the same as the height of the front wall 41 of the second water receiving tank, since the structural shape of the fresh air module 20 is different from that of the heat exchanger, the position where the condensate generated on the fresh air module drips into the first water receiving tank 30 is higher than the position where the condensate generated by the heat exchanger drips into the second water receiving tank 40. Therefore, an additional water-blocking component is needed to block the condensate generated from the fresh air module 20 so that the condensate can flow smoothly into the first water receiving tank 30. The water-blocking component is elongated and needs to be positioned above the front wall 34 of the first water receiving tank to allow the condensate generated on the fresh air module 20 to flow smoothly into the first water receiving tank 30. The water-blocking component can be positioned below both the fresh air module 20 and the heat exchanger, or it can be positioned below the fresh air module 20 alone. Since the water-blocking component is mainly used to block the condensate flowing down from the fresh air module 20, in this embodiment, the water-blocking component is positioned below the fresh air module 20. The water-blocking component can be installed by connecting it to the position on the front frame of the indoor air unit corresponding to the fresh air module 20, or by setting it on the front side wall 34 of the first water receiving tray corresponding to the fresh air module 20, thereby extending the height of the front side wall 34 of the first water receiving tray to block the condensate generated from the fresh air module 20. Alternatively, a slot can be set on the front frame of the indoor air unit between the fresh air module 20 and the first water receiving tray 30, and the water-blocking component can be directly inserted between the fresh air module 20 and the first water receiving tray 30 during assembly to prevent the condensate dripping from the fresh air module 20 from dripping into the air duct.

[0052] In another embodiment, the housing 10 includes a face frame, on which a water baffle corresponding to the fresh air module 20 is provided, and the water baffle is located above the wall of the first water receiving tank 30.

[0053] Specifically, when the height of the front wall 34 of the first water receiving tank is the same as the height of the front wall 41 of the second water receiving tank, the position where the condensate water generated on the fresh air module 20 drips into the first water receiving tank 30 will be higher than the position where the condensate water generated by the heat exchanger drips into the second water receiving tank 40. This is due to the difference in structural shape between the fresh air module 20 and the heat exchanger. Therefore, to prevent the condensate water dripping from the fresh air module 20 from falling into the air duct, an additional baffle plate needs to be installed to block the condensate water generated from the fresh air module, so that the condensate water can flow smoothly into the first water receiving tank 30. The baffle plate can be integrated with the face frame and is located between the fresh air module 20 and the first water receiving tank 30. When the condensate water generated on the fresh air module 20 drips at a low position, it will flow directly into the first water receiving tank 30. When the condensate water generated on the fresh air module 20 drips at a high position, it will first flow onto the baffle plate, and then flow into the first water receiving tank 30 through the baffle plate, and finally be discharged from the drain hole 311 to prevent condensate water from flowing into the air duct.

[0054] Please seeFigure 1 and Figure 6 In one embodiment, the housing 10 includes a chassis 11, on which a first water receiving trough 30 is formed. Specifically, the chassis 11 is mainly used to install components such as the fresh air module 20, heat exchanger, and fan wheel in the indoor unit of the air conditioner. The chassis 11 is made of a rigid material, which can be ABS, HIPS, PP, PC, or other rigid materials, or metal or alloy materials, etc., without specific limitations. The first water receiving trough 30 is directly formed on the chassis 11, which can reduce the process of separately producing the water receiving trough, further improve the production efficiency of the indoor unit of the air conditioner, and at the same time reduce costs.

[0055] Please see Figure 3 and Figure 6 It is worth mentioning that the bottom of the first sub-slot 31 is provided with an installation port 312 corresponding to the air inlet 21 of the fresh air module 20, and the edge of the installation port 312 extends toward the fresh air module 20 to form a positioning part 313.

[0056] Specifically, the mounting port 312 allows the air inlet 21 of the fresh air module 20 to be installed, and also serves to position the fresh air module 20. When the air inlet 21 of the fresh air module 20 corresponds to the mounting port 312 and is installed on the chassis 11, the fresh air module 20 may move or shake slightly, and there is a gap between the air inlet 21 and the mounting port 312, which may cause air leakage during the operation of the fresh air module 20. Therefore, a positioning part 313 is formed extending from the edge of the mounting port 312 toward the fresh air module 20. The air inlet 21 is fitted onto the outside of the positioning part 313, so that the outer wall of the positioning part 313 fits against the inner wall of the air inlet 21, and the positioning part 313 extends into the air inlet 21, thereby preventing air leakage during the operation of the fresh air module 20. At the same time, the positioning part 313 also serves to limit the position of the fresh air module 20, preventing it from shaking and changing position after being installed on the positioning part 313.

[0057] Please see Figure 3 and Figure 7 In one embodiment, the indoor unit of the air conditioner further includes a first rubber pad 70, which is located between the bottom of the fresh air module 20 and the first sub-slot 31.

[0058] Specifically, the first rubber pad 70 is made of rubber. The first rubber pad 70 can be a transparent pad, an EVA pad, or a transparent pad made of PU, PVC, EPDM, etc. Of course, in other embodiments, it can also be a sponge pad, foam pad, etc., and no specific limitation is made here. The shape of the first rubber pad 70 is the same as the shape of the positioning part 313, and it is square. The first rubber pad 70 adapts to the shape of the positioning part 313 and is installed on the outer wall surface of the positioning part 313. The air inlet 21 of the fresh air module 20 is installed at the mounting port 312 and directly contacts the bottom of the first sub-slot 31. After the fresh air module 20 is installed at the mounting port 312, there will still be a certain gap between the inner side of the air inlet 21 and the positioning part 313, resulting in poor sealing. During the operation of the fresh air module 20, air leakage will occur, which will affect the air intake of the fresh air module 20. Therefore, a first rubber pad 70 can be set between the fresh air module 20 and the bottom of the first sub-slot 31 to enhance the sealing between the fresh air module 20 and the bottom of the first sub-slot 31, so that the fresh air module 20 is not prone to air leakage during operation.

[0059] Please see Figure 1 and Figure 7 In one embodiment, the indoor unit of the air conditioner further includes an adapter 50, which is installed at the mounting port 312 and communicates with the air inlet 21. Specifically, the adapter 50 includes a first part 51 installed at the mounting port 312 and a second part 52 connected to the fresh air duct. The first part 51 and the second part 52 are connected. The first part 51 is provided with a first connection port 511, which is installed at the mounting port 312 and communicates with the air inlet 21. When the fresh air duct is connected to the second part 52, fresh air can be delivered from the fresh air duct to the adapter 50 and enter the fresh air module 20 through the adapter 50. Then, the fresh air module 20 filters the fresh air. In this embodiment, the air outlet 23 of the fresh air module 20 is designed to face forward. After the fresh air module 20 has finished processing the fresh air, the fresh air can be directly blown into the room through the forward-facing air outlet 23. The air inlet 21 of the fresh air module 20 is square in shape, and the mounting port 312 is also square in shape. Correspondingly, the first connection port 511 on the adapter 50 for connecting with the mounting port 312 is also square in shape. Of course, in other embodiments, the air inlet 21, mounting port 312 and first connection port 511 of the fresh air module 20 can also be designed in other shapes, and no specific restrictions are made here.

[0060] The second part 52 of the adapter 50 is provided with a second connection port 521. The second connection port 521 is mainly used to connect the fresh air duct. Since the fresh air duct is usually a circular flexible tube, the shape of the second connection port 521 is different from that of the first connection port 511. The shape of the second connection port 521 corresponds to the shape of the fresh air duct and is circular. As for the number of second connection ports 521, the number of second connection ports 521 can be one or more (the "multiple" includes two or more). In this embodiment, the number of second connection ports 521 is set to three, and the three second connection ports 521 face different directions to meet the different needs of users when connecting the fresh air duct. The three second connection ports 521 include a left outlet 521a, a right outlet 521b, and a rear outlet 521c. Therefore, the adapter 50 has three directions: left outlet, right outlet, and rear outlet. During after-sales installation, the appropriate connection port can be selected according to the installation environment. The adapter 50 is also equipped with two rubber plugs 90. When one of the left outlet 521a, right outlet 521b, and rear outlet 521c is connected to the fresh air duct, the other two outlets are blocked with rubber plugs 90 to prevent fresh air from leaking out of the other two connection ports during use. Specifically, when the fresh air duct is connected to the left outlet 521a, the two rubber plugs 90 block the right outlet 521b and the rear outlet 521c; when the fresh air duct is connected to the right outlet 521b, the two rubber plugs 90 block the left outlet 521a and the rear outlet 521c; and when the fresh air duct is connected to the rear outlet 521c, the two rubber plugs 90 block the left outlet 521a and the right outlet 521b.

[0061] Meanwhile, a second rubber gasket 80 can be provided between the first connection port 511 and the mounting port 312 on the adapter 50 to increase the sealing performance of the adapter 50 after it is installed in the mounting port 312 and prevent air leakage. The second rubber gasket 80 is also made of rubber and can be a transparent gasket, an EVA gasket, or a transparent gasket made of PU, PVC, EPDM, etc. The shape of the second rubber gasket 80 is the same as that of the mounting port 312, and it is also square.

[0062] Please see Figure 4 and Figure 5 In one embodiment, the bottom of the chassis 11 is provided with a clearance groove 60, which is located below the fresh air module 20. The mounting port 312 passes through the clearance groove 60, and the adapter 50 is installed in the clearance groove 60. Specifically, the clearance groove 60 is mainly used for the installation of the adapter 50 and provides space for the adapter 50 so that when the adapter 50 is installed in the clearance groove 60, there is enough space for the duct to run after connecting the fresh air duct.

[0063] Please see Figure 5In one embodiment, a buckle 61 is provided in the clearance groove 60, and the buckles 61 are located on opposite sides of the adapter 50 to engage and fix the adapter 50. Specifically, the adapter 50 is provided with a snap-fit ​​structure, and two buckles 61 are provided in the clearance groove 60 and on opposite sides of the adapter 50. The snap-fit ​​structure on the adapter 50 and the buckles 61 cooperate with each other, so that the adapter 50 is fixedly installed at the mounting port 312. Since a second rubber pad 80 is provided between the first connection port 511 on the adapter 50 and the mounting port 312, the height of the buckle 61 is higher than the height of the snap-fit ​​structure on the adapter 50. The thickness of the second rubber pad 80 is exactly the height difference between the height of the buckle 61 and the height of the snap-fit ​​structure on the adapter 50. In this way, the second rubber pad 80 can better cooperate with the adapter 50 to fix the adapter 50 in place at the mounting port 312 and prevent it from falling off easily.

[0064] Please see Figure 5 In one embodiment, a limiting strip 62 is provided in the clearance groove 60. The limiting strip 62 is located on opposite sides of the adapter 50 to limit the adapter 50. Specifically, the limiting strip 62 is provided on opposite sides of the clearance groove 60 where the buckle 61 is not provided. The length of the limiting strip 62 can be longer than the length of the adapter 50, or equal to or shorter than the length of the adapter 50. If the buckles 61 are located on the left and right sides of the adapter 50, the adapter 50 will be fixed in the left and right direction and will not move when it is engaged with the mounting port 312 by the buckles 61, but the adapter 50 may move in the front and back direction. If the buckles 61 are located on the front and back sides of the adapter 50, the adapter 50 will be fixed in the front and back direction and will not move when it is engaged with the mounting port 312 by the buckles 61, but the adapter 50 may move in the left and right direction. Therefore, instead of buckles 61 on opposite sides in the clearance groove 60, limit strips 62 are provided. These limit strips 62 mainly limit the adapter 50 to prevent it from moving in the opposite direction of the limit strips 62 after it is installed in the mounting port 312, which would cause the adapter 50 to be misaligned after being installed in the clearance groove 60 and thus cause air leakage.

[0065] Please see Figure 1 , Figure 4 and Figure 8Considering that after the fresh air module 20 is installed on the chassis 11, under the action of external force, the installation of the fresh air module 20 is unstable and its position may change, thereby affecting the use of the fresh air module 20 function, or causing the connection between the air inlet 21 and the mounting port 312 of the fresh air module 20 to be unstable, resulting in air leakage, in order to solve this problem, a fixing post 22 can be set on the outer surface of the fresh air module 20, and a fixing hole 33 is provided on the front side wall 34 of the first water receiving tank. The fixing post 22 and the fixing hole 33 are connected to each other so that the fresh air module 20 is fixedly installed on the chassis 11, thereby avoiding the above-mentioned problems.

[0066] In one embodiment, the indoor unit of the air conditioner also includes a fan and a motor mounted on the chassis 11. The fan is located between the heat exchanger 300 and the chassis 110. Specifically, the motor is mounted in a motor slot on the chassis 11, and the fan is mounted in a fan slot on the chassis 11. When the indoor unit of the air conditioner is working, the motor shaft rotates, thereby driving the fan to rotate. The fan is located between the heat exchanger and the chassis 11. The heat exchanger is fixedly mounted on the chassis 11 and can exchange heat with the air flowing through the fan, thereby heating or lowering the indoor air temperature. The air outlet of the fresh air module 20 can also be oriented towards the fan, so that the fresh air filtered by the fresh air module 20 flows through the fan for heat exchange, thereby heating or lowering the fresh air temperature.

[0067] This invention also proposes an air conditioner, which includes an outdoor unit and an indoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. As for the type of air conditioner, this air conditioner is a wall-mounted air conditioner.

[0068] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
