Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to an indoor unit of an air conditioner. Background Art

[0002] When in use, the duct air conditioner is usually installed inside the suspended ceiling, which means that when designing and manufacturing the duct air conditioner, the requirements for its thickness in the up and down directions are relatively high, that is, the duct air conditioner needs to be designed to be as thin as possible, while the requirements for its length in the left and right directions and the width in the front and back directions are relatively low.

[0003] If the duct unit is used directly as a kitchen air conditioner, since the kitchen space is usually around 4 square meters, when installing the duct unit, it is necessary to run the pipes in the ceiling space and make way for the flue, which makes the originally narrow space extremely limited and it is difficult to meet the usage needs in the kitchen space. Utility Model Content

[0004] The utility model aims to provide an air conditioner indoor unit to solve the technical problem that the solution of directly using a duct unit as a kitchen air conditioner is difficult to meet the use requirements in the kitchen space.

[0005] The utility model provides an air-conditioning indoor unit, including an L-shaped heat exchanger, a water pump, an electric control box and a wind wheel assembly, the L-shaped heat exchanger including a first side wall extending in the left-right direction and a second side wall extending in the front-to-back direction, the water pump and the electric control box are arranged on a side of the first side wall away from the second side wall, and the water pump and the electric control box are arranged in the front-to-back direction; the L-shaped heat exchanger, the water pump and the electric control box form an installation cavity, and the wind wheel assembly is arranged in the installation cavity.

[0006] By setting up an air-conditioning indoor unit mainly composed of an L-shaped heat exchanger, a water pump, an electrical control box and a wind wheel assembly, when the air-conditioning indoor unit needs to be operated, the wind wheel assembly is started, and a negative pressure effect is generated in the installation cavity surrounded by the L-shaped heat exchanger, the water pump and the electrical control box, so that the external wind can be discharged after the heat exchange treatment of the heat exchanger, thereby performing corresponding cooling or heating treatment for the indoor environment.

[0007] The air conditioner indoor unit arranges the water pump and the electric control box on one side of the L-shaped heat exchanger. On the one hand, the water pump and the electric control box can be inspected and wired on the same side of the air conditioner indoor unit, which is convenient for operation. On the other hand, it can also avoid the water pump and the electric control box from blocking the air intake process, thereby ensuring the air intake volume. By placing the wind wheel assembly in the installation cavity surrounded by the L-shaped heat exchanger, the water pump and the electric control box, the internal space of the air conditioner indoor unit is reasonably utilized, the space occupied around the L-shaped heat exchanger is reduced, and the structure of the air conditioner indoor unit is compacted, so that the air conditioner indoor unit can be installed in a small kitchen space and used as a kitchen air conditioner, effectively solving the technical problem that the existing duct air conditioner is difficult to meet the use requirements in the kitchen space.

[0008] Furthermore, the air conditioner indoor unit also includes a water receiving pan and a partition, the water receiving pan is provided with a water receiving area and a clearance area, wherein the water receiving area is located below the L-shaped heat exchanger, the water pump is provided in the water receiving area, and the water inlet of the water pump is connected to the water receiving area; the partition is sealed and connected to the water receiving pan, the partition separates the water receiving area from the clearance area, and the electric control box is provided in the clearance area. When the air conditioner indoor unit is operated in cooling mode, the water receiving area of ​​the water receiving pan can be used to collect the condensed water generated during the operation of the L-shaped heat exchanger, so as to prevent the condensed water from dripping onto the ceiling and causing damage to the ceiling. At the same time, by providing the clearance area on the water receiving pan and separating the clearance area from the water receiving area by using the partition sealed and connected to the water receiving pan, the electric control box provided in the clearance area can be protected from water, so as to prevent the condensed water in the water receiving pan from splashing onto the electric control box and causing damage to the electric control box.

[0009] Furthermore, the electric control box includes a vertical section and a horizontal section arranged in an L shape, wherein the vertical section is arranged side by side with the water pump, and the horizontal section is located above the water pump. This arrangement can utilize the remaining height space above the water pump to partially accommodate the electric control box, thereby realizing effective utilization of the space above the water pump, while ensuring the electric control function of the electric control box, it will not occupy the external space of the shell, thereby ensuring the compact structure of the air conditioner indoor unit.

[0010] Furthermore, the water receiving pan is provided with a drainage port, and the water receiving area is provided with a water guiding slope and a water guiding channel, wherein the water guiding slope gradually slopes downward from the edge of the water receiving pan toward the water guiding channel; the drainage port is connected to the outlet of the water guiding channel. This arrangement enables the condensed water to be discharged under the action of its own gravity, and even when the water pump is stopped, the condensed water can be prevented from gathering in the water receiving pan, thereby ensuring the timely drainage.

[0011] Further, a sinking structure is provided in the water receiving area opposite to the water pump. The water receiving tray includes a first edge and a second edge that are opposite and spaced apart in the left-right direction. Among them, the sinking structure is provided near the first edge, the drain port is provided near the second edge, and the water guiding channel connects the sinking structure and the drain port. The above layout form of the water receiving tray enables the water guiding channel to penetrate the length area of the water receiving tray, so that the condensed water dripping to various positions in the length direction of the water receiving tray can flow into the water guiding channel in a timely manner under the guiding action of the water guiding slope. In addition, the setting of the sinking structure can achieve the precipitation of impurities in the condensed water, prevent the impurities from being sucked into the water pump and blocking or even damaging the water pump, and plays a certain protective role for the water pump.

[0012] Further, the water receiving tray has a rectangular structure, and the sinking structure and the drain port are diagonally arranged relative to the water receiving tray. The above setting can not only increase the distribution range of the water guiding channel along the length direction of the water receiving tray, but also increase the distribution range of the water guiding channel along the width direction of the water receiving tray, so that the condensed water dripping to each position of the water receiving tray can be discharged in a timely manner; and / or, the water guiding channel has a groove structure. This structural form of the water guiding channel can not only form an effective drainage channel, but also increase the structural strength of the water receiving tray to a certain extent.

[0013] Further, a limiting structure is provided in the water receiving area, and the limiting structure is used to fix the L-shaped heat exchanger. This setting can fix the L-shaped heat exchanger on the water receiving tray, play a limiting role on the water receiving tray, prevent the L-shaped heat exchanger from moving on the water receiving tray, and ensure the installation stability of the L-shaped heat exchanger; and / or, a reinforcing rib is provided on the side of the water receiving area facing away from the L-shaped heat exchanger. This setting can enhance the structural strength of the water receiving tray, increase the anti-deformation ability of the water receiving tray, extend the service life of the water receiving tray, and avoid the deformation of the water receiving tray when the water volume is large, ensuring the water storage effect; and / or, a water absorption layer is fixedly provided on the side of the water receiving area facing away from the L-shaped heat exchanger. This setting can absorb the condensed dew attached to the water receiving tray, and avoid damage to the ceiling caused by the condensed dew dripping from the back of the water receiving tray into the ceiling space.

[0014] Further, along the front-rear direction, the water pump is adjacent to the first side wall, and the electric control box is arranged at a position where the water pump is away from the first side wall. This setting makes the electric control box roughly on the air flow path, so that when the air conditioner indoor unit operates in the cooling mode, the air conditioner air can flow through the surface of the electric control box to take away the heat generated by the electric control box to ensure the electric control performance of the electric control box.

[0015] Furthermore, the indoor air conditioner further includes a housing, and the L-shaped heat exchanger, the water pump, the electric control box and the wind wheel assembly are all arranged inside the housing. The housing is provided with a first air inlet at a position adjacent to and opposite the first side wall, and the housing is provided with a second air inlet at a position adjacent to and opposite the second side wall. The housing is further provided with an air outlet for guiding the air conditioner air into the room. By providing air inlets at positions adjacent to and opposite the first side wall and the second side wall of the housing, the indoor air conditioner forms an air inlet mode with air inlet from two sides, thereby increasing the air inlet volume.

[0016] Furthermore, the housing includes a first upright post and a second upright post that are opposite and spaced apart along the left-right direction, and a first air inlet is formed between the first upright post and the second upright post. This form of forming the first air inlet by using the space between the two upright posts allows the air flow to enter through the first air inlet with almost no obstruction, increasing the air inlet area of the first air inlet; and / or, along the front-rear direction, the air outlet is opposite to the first air inlet. This setting can shorten the air flow path from the first air inlet to the air outlet, reducing the air volume loss.

[0017] Furthermore, the L-shaped heat exchanger is a multi-row heat exchanger. By setting the L-shaped heat exchanger as a multi-row heat exchanger, the heat exchange capacity of the L-shaped heat exchanger can be increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Currently, the interior of the air duct machine is divided into a heat exchanger chamber and a blower chamber. In order to increase the heat exchange area, the heat exchanger is usually placed obliquely in the heat exchanger chamber, which results in a relatively large width of the air duct machine and occupies a large amount of space in the ceiling interior along the front-rear direction. Moreover, the existing air duct machines mainly use the side air outlet method. In order to increase the air volume, the air outlets are usually made thinner and longer, which results in a relatively long length of the air duct machine and occupies a large amount of space in the ceiling interior along the left-right direction.

[0034] Therefore, if the structure of the existing air duct machine is directly transferred to the kitchen air conditioner, it is obvious that the size is too large to meet the usage requirements of the narrow kitchen space, and there is a large room for improvement.

[0035] Based on this, the purpose of the present utility model is to provide an indoor unit of an air conditioner to solve the technical problem that it is difficult to meet the usage requirements in the kitchen space when directly using the air duct machine as the kitchen air conditioner.

[0036] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] Embodiment 1

[0038] Figure 1 A top structural cross-sectional view of the air conditioner indoor unit provided in the first embodiment; Figure 2 This is a schematic diagram of the internal structure of the air conditioner indoor unit provided in this embodiment. Figure 1 and Figure 2 As shown, this embodiment provides an air-conditioning indoor unit, including an L-shaped heat exchanger 100, a water pump 200, an electric control box 300 and a wind wheel assembly 400, wherein the L-shaped heat exchanger 100 includes a first side wall 110 extending in the left-right direction and a second side wall 120 extending in the front-back direction, the water pump 200 and the electric control box 300 are arranged on the side of the first side wall 110 away from the second side wall 120, and the water pump 200 and the electric control box 300 are arranged in the front-back direction; the L-shaped heat exchanger 100, the water pump 200 and the electric control box 300 surround an installation cavity, and the wind wheel assembly 400 is arranged in the installation cavity.

[0039] When the air conditioner indoor unit needs to be operated, the wind wheel assembly 400 is started, and a negative pressure effect is generated in the installation cavity surrounded by the L-shaped heat exchanger 100, the water pump 200 and the electrical control box 300, so that the external wind can be discharged after the heat exchange treatment of the heat exchanger, thereby performing corresponding cooling or heating treatment for the indoor environment.

[0040] The air conditioner indoor unit arranges the water pump 200 and the electric control box 300 on one side of the L-shaped heat exchanger 100. On the one hand, the water pump 200 and the electric control box 300 can be inspected and wired on the same side of the air conditioner indoor unit, which is convenient for operation. On the other hand, it can also avoid the water pump 200 and the electric control box 300 from blocking the air intake process, thereby ensuring the air intake volume. By placing the wind wheel assembly 400 in the installation cavity surrounded by the L-shaped heat exchanger 100, the water pump 200 and the electric control box 300, the internal space of the air conditioner indoor unit is reasonably utilized, the space occupied around the L-shaped heat exchanger 100 is reduced, and the structure of the air conditioner indoor unit is compacted, so that the air conditioner indoor unit can be installed in a small kitchen space and used as a kitchen air conditioner, effectively solving the technical problem that the existing duct machine is difficult to meet the use requirements in the kitchen space.

[0041] It should be noted that, in this embodiment, the “left and right direction” can be Figure 2 The arrows ab in the figure indicate that the “front and back directions” can be represented by Figure 2 The arrow cd in the figure indicates that the “up and down directions” can be represented by Figure 2is represented by the arrow ef in the figure.

[0042] Figure 3 is one of the external structure schematic diagrams of the air conditioner indoor unit provided in the first embodiment; Figure 4 is the second external structure schematic diagram of the air conditioner indoor unit provided in the first embodiment. Please continue to refer to Figure 1 and Figure 2 and in combination with Figure 3 and Figure 4 In this embodiment, the air conditioner indoor unit may further include a housing 700. Among them, the L-shaped heat exchanger 100, the water pump 200, the electric control box 300, and the wind wheel assembly 400 are all arranged inside the housing 700. The housing 700 is provided with a first air inlet 710 at a position adjacent to and opposite the first side wall 110, and the housing 700 is provided with a second air inlet 720 at a position adjacent to and opposite the second side wall 120. The housing 700 is further provided with an air outlet 730 for guiding the air conditioner air to the room.

[0043] During the operation of the air conditioner indoor unit, under the action of the wind wheel assembly 400, the external air flow enters the housing 700 through the first air inlet 710 and the second air inlet 720, and after heat exchange treatment with the L-shaped heat exchanger 100, it is sent into the indoor space through the air outlet 730.

[0044] The above setting of the housing 700 can form a relatively closed space from the first air inlet 710 and the second air inlet 720 to the air outlet 730, which is beneficial to the refrigeration or heating of the air flow and improves the energy efficiency. In addition, by providing air inlets at positions adjacent to and opposite the first side wall 110 and the second side wall 120 of the housing 700, the air conditioner indoor unit forms an air inlet mode with air inlet from two sides, increasing the air inlet volume.

[0045] Please continue to refer to Figure 1 and Figure 4 In this embodiment, the housing 700 may include a first column 741 and a second column 742 that are opposite and spaced apart in the left-right direction. A first air inlet 710 is formed between the first column 741 and the second column 742.

[0046] This form of forming the first air inlet 710 by using the interval between the two columns allows the air flow to enter through the first air inlet 710 with almost no obstruction, increasing the air inlet area of the first air inlet 710.

[0047] Similarly, the housing 700 may further include a third column that is opposite and spaced apart from the second column 742 in the front-rear direction. Among them, a second air inlet 720 is formed between the third column and the first column 741.

[0048] This form that also utilizes the space between the two columns to form the second air inlet 720 allows the air to enter through the second air inlet 720 with almost no obstruction, increasing the air inlet area of the second air inlet 720.

[0049] Please continue to refer to Figure 1 and Figure 4 In this embodiment, along the front-back direction, the air outlet 730 is opposite to the first air inlet 710. Among them, the housing 700 includes a front wall 770 disposed opposite to the first air inlet 710. That is to say, the air outlet 730 is opened on the front wall 770.

[0050] By setting the air outlet 730 to be opposite to the first air inlet 710 along the front-back direction, the air flow path from the first air inlet 710 to the air outlet 730 can be shortened, reducing the air volume loss.

[0051] In this embodiment, the air inlet and outlet paths of the air conditioner indoor unit are as shown by the hollow arrows in Figure 1 Among them.

[0052] Please continue to refer to Figure 1 In this embodiment, the housing 700 may further include a left wall 750 that is opposite to and spaced from the second air inlet 720 along the left-right direction. Among them, the water pump 200 and the electric control box 300 are close to the left wall 750.

[0053] It can be understood that in other embodiments, the second side wall 120 of the L-shaped evaporator may also be disposed close to the left wall 750 of the housing 700. At this time, the second air inlet 720 is disposed at the left wall 750 of the housing 700, and the second air inlet 720 is formed on the left side of the housing 700, while the water pump 200 and the electric control box 300 are disposed on the right side of the housing 700.

[0054] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the air conditioner indoor unit is generally a cuboid structure. Among them, the dimension of the housing 700 along the left-right direction is less than 600 mm, the dimension of the housing 700 along the front-back direction is less than 250 mm, and the dimension of the housing 700 along the up-down direction is less than 230 mm. Taking Figure 3 as an example, that is, L < 600 mm, B < 250 mm, H < 230 mm.

[0055] By setting the housing 700 within the above-mentioned dimensional range, after removing the aluminum gusset plate, the air conditioner indoor unit can be directly inserted into the ceiling internal space from bottom to top, realizing the installation without damaging the ceiling and cutting the keel on the basis of the kitchen ceiling that has been decorated.

[0056] In this embodiment, the L-shaped heat exchanger 100 can be a multi-row heat exchanger.

[0057] By configuring the L-shaped heat exchanger 100 as a multi-row heat exchanger, the heat exchange capacity of the L-shaped heat exchanger 100 can be increased. For example, when the L-shaped heat exchanger 100 is used as an evaporator, this configuration can increase the cooling capacity of the L-shaped heat exchanger 100 .

[0058] Specifically, the L-type heat exchanger 100 can be arranged in two rows or three rows according to the heat exchange requirement.

[0059] Figure 5 This is a structural diagram of the water receiving tray 500 of the air conditioner indoor unit provided in this embodiment. Figure 2 , and combined with Figure 5 In this embodiment, the air conditioner indoor unit may further include a water receiving pan 500 and a partition 600, the water receiving pan 500 is provided with a water receiving area 510 and a clearance area 520, wherein the water receiving area 510 is located below the L-shaped heat exchanger 100, the water pump 200 is arranged in the water receiving area 510, and the water inlet of the water pump 200 is connected to the water receiving area 510; the partition 600 is sealedly connected to the water receiving pan 500, the partition 600 separates the water receiving area 510 from the clearance area 520, and the electric control box 300 is arranged in the clearance area 520.

[0060] When the indoor unit of the air conditioner is operated in cooling mode, the water receiving area 510 of the water receiving tray 500 can be used to collect the condensed water generated during the operation of the L-shaped heat exchanger 100, so as to prevent the condensed water from dripping onto the ceiling and causing damage to the ceiling. At the same time, by providing a clearance area 520 on the water receiving tray 500 and separating the clearance area 520 from the water receiving area 510 by using a partition 600 sealedly connected to the water receiving tray 500, the electric control box 300 provided in the clearance area 520 can be waterproofed, so as to prevent the condensed water in the water receiving tray 500 from splashing onto the electric control box 300 and causing damage to the electric control box 300.

[0061] It should be noted that the partition 600 and the water receiving tray 500 can be sealed by providing a sealing strip between the partition 600 and the water receiving tray 500; or a sealing structure in which a convex rib and a groove cooperate with each other can be provided between the partition 600 and the water receiving tray 500 to achieve a sealed connection between the partition 600 and the water receiving tray 500.

[0062] In this embodiment, the water receiving tray 500 can serve as the bottom wall of the housing 700 .

[0063] Please continue to refer to Figure 5 In this embodiment, the water receiving tray 500 is provided with a drain outlet 530, and the water receiving area 510 is provided with a water guiding slope 511 and a water guiding channel 512, wherein the water guiding slope 511 gradually tilts downward from the edge of the water receiving tray 500 to the direction of the water guiding channel 512; the drain outlet 530 is connected to the outlet of the water guiding channel 512.

[0064] When the condensed water drops to the water receiving area 510, it will flow to the water guide channel 512 under the guidance of the water guide slope 511, and further flow to the drain port 530 along the water guide channel 512, and be discharged from the drain port 530. This arrangement allows the condensed water to be discharged under its own gravity, and even when the water pump 200 is stopped, it can prevent the condensed water from gathering in the water receiving pan 500, thereby ensuring the timely drainage.

[0065] It should be noted that, in this embodiment, the drain port 530 provided on the water receiving tray 500 can be used as a backup port, and the water pump 200 drainage is the main drainage method. Among them, the water pump 200 has an independent water outlet.

[0066] In this embodiment, a pagoda-shaped joint may be provided at the drain outlet 530 , so as to reduce the risk of the drain pipe or the plug coming out when it is connected to the drain outlet 530 .

[0067] Please continue to refer to Figure 5 In this embodiment, the water receiving area 510 is provided with a sinking structure 513 opposite to the water pump 200, and the water receiving tray 500 includes a first edge 540 and a second edge 550 which are opposite to and spaced apart in the left-right direction, wherein the sinking structure 513 is arranged close to the first edge 540, the drain outlet 530 is arranged close to the second edge 550, and the water guide channel 512 connects the sinking structure 513 and the drain outlet 530.

[0068] The above-mentioned layout of the water receiving tray 500 enables the water pump 200 and the drain outlet 530 to be arranged at both ends of the water receiving tray 500 in the length direction, so that the water guide channel 512 runs through the length area of ​​the water receiving tray 500, so that the condensed water dripping to various places in the length direction of the water receiving tray 500 can flow into the water guide channel 512 in time under the guidance of the water guide slope 511, and then be discharged along the water guide channel 512, thereby avoiding the accumulation of condensed water in the local area of ​​the water receiving tray 500 and ensuring the timeliness of drainage.

[0069] In addition, the setting of the sinking structure 513 can achieve the precipitation of impurities in the condensed water, preventing the impurities from being sucked into the water pump 200 and clogging or even damaging the water pump 200, thereby playing a certain protective role for the water pump 200.

[0070] In this embodiment, since the water receiving tray 500 is provided with a clearance area 520 on one side of the first edge 540 , the first edge 540 is a multi-angle edge; and the second edge 550 is a straight edge.

[0071] Please continue to refer to Figure 5 In this embodiment, the water receiving tray 500 is a rectangular structure, and the sinking structure 513 and the drain port 530 are arranged diagonally relative to the water receiving tray 500. In other words, the water guide channel 512 is arranged along the diagonal line of the water receiving tray 500.

[0072] The above settings can not only increase the distribution range of the water guiding channels 512 along the length direction of the water receiving tray 500, but also increase the distribution range of the water guiding channels 512 along the width direction of the water receiving tray 500, so that the condensed water dripping to various positions of the water receiving tray 500 can be discharged in time.

[0073] Please continue to refer to Figure 5 , in this embodiment, the water guiding channels 512 are in a groove structure.

[0074] This structural form of the water guiding channels 512 can not only form an effective drainage channel, but also increase the structural strength of the water receiving tray 500 to a certain extent.

[0075] In other embodiments, the water guiding channels 512 can also be formed by the intersection of the water guiding inclined surfaces 511 on both sides.

[0076] Please continue to refer to Figure 5 , in this embodiment, a limiting structure 514 can also be provided in the water receiving area 510, where the limiting structure 514 is used to fix the L-shaped heat exchanger 100.

[0077] The setting of the above limiting structure 514 can fix the L-shaped heat exchanger 100 on the water receiving tray 500, play a limiting role on the water receiving tray 500, prevent the L-shaped heat exchanger 100 from moving around on the water receiving tray 500, and ensure the installation stability of the L-shaped heat exchanger 100.

[0078] Please continue to refer to Figure 5 , in this embodiment, the limiting structure 514 can include a plurality of limiting ribs arranged at intervals along the direction of the L-shaped heat exchanger 100. Among them, a fixing area is formed between any two adjacent limiting ribs, and the L-shaped heat exchanger 100 is clamped in the plurality of fixing areas to achieve fixation on the water receiving tray 500.

[0079] Figure 6 This is a schematic bottom view structure diagram of the air conditioner indoor unit provided in Embodiment 1. As Figure 6 shown, a reinforcing rib 560 is provided on the side of the water receiving area 510 facing away from the L-shaped heat exchanger 100.

[0080] The setting of the above reinforcing rib 560 can enhance the structural strength of the water receiving tray 500, increase the anti-deformation ability of the water receiving tray 500, extend the service life of the water receiving tray 500, and avoid deformation of the water receiving tray 500 when the water volume is large, ensuring the water storage effect.

[0081] Please continue to refer to Figure 6 , in this embodiment, a water absorption layer 570 is fixedly provided on the side of the water receiving area 510 facing away from the L-shaped heat exchanger 100.

[0082] The above-mentioned water absorption layer 570 can absorb the condensed water adhering to the back surface of the water receiving tray 500, avoiding damage to the ceiling caused by the condensed water dripping from the back surface of the water receiving tray 500 into the ceiling space.

[0083] Specifically, the material of the water absorption layer 570 can be sponge.

[0084] Please continue to refer to Figure 1 and Figure 2 In this embodiment, along the front-rear direction, the water pump 200 is disposed adjacent to the first side wall 110, and the electric control box 300 is disposed at a position away from the first side wall 110 of the water pump 200. That is to say, in the direction from the first side wall 110 to the front wall 770 of the housing 700, the water pump 200 and the electric control box 300 are sequentially arranged. Compared with the electric control box 300, the water pump 200 is closer to the L-shaped heat exchanger 100.

[0085] By disposing the electric control box 300 away from the L-shaped heat exchanger 100, the electric control box 300 is substantially on the air flow path, so that when the air conditioner indoor unit operates in the cooling mode, the air-conditioning air can flow through the surface of the electric control box 300 to take away the heat generated by the electric control box 300 to ensure the electric control performance of the electric control box 300.

[0086] It should be noted that in other embodiments, the electric control box 300 can also be disposed at a position close to the L-shaped heat exchanger 100 in the front-rear direction, and the water pump 200 can be disposed at a position away from the first side wall 110 of the electric control box 300.

[0087] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the wind wheel assembly 400 can include a biaxial motor 410, a wind wheel 420, and a motor bracket 430. Among them, the two output shafts of the biaxial motor 410 are respectively arranged in opposite directions along the left-right direction. The number of wind wheels 420 is two, and the two wind wheels 420 are respectively fixedly sleeved on the two output shafts of the biaxial motor 410; the motor bracket 430 is fixedly connected to the housing 700, and the biaxial motor 410 is installed on the motor bracket 430.

[0088] When the air conditioner indoor unit operates, the biaxial motor 410 outputs rotational power through two output shafts arranged in opposite directions to drive the wind wheels 420 fixedly sleeved on the output shafts to rotate, so as to form a negative pressure inside the housing 700, and utilize the negative pressure effect to enable the outside air flow to be inhaled, and then heat exchange with the L-shaped heat exchanger 100 and then sent into the indoor space, so as to achieve the purpose of cooling or heating.

[0089] With this arrangement of the wind wheel assembly 400, during the operation of the air conditioner indoor unit, the flow path of the external air flow is to first pass through the L-shaped heat exchanger 100 and then through the wind wheel assembly 400, which is a suction air flow process. Compared with the blowing air flow process of a conventional duct machine, the heat exchange effect is improved. Moreover, this arrangement can also minimize the volume of the air conditioner indoor unit while ensuring the heat exchange capacity.

Among them, the vertical section 310 is arranged side by side with the water pump 200, and the horizontal section 320 is located above the water pump 200.

[0093] This arrangement can utilize the remaining height space above the water pump 200 to partially accommodate the electric control box 300, realizing the effective utilization of the space above the water pump 200. While ensuring the electric control function of the electric control box 300, it does not occupy the external space of the housing 700, ensuring the structural compactness of the air conditioner indoor unit.

[0094] Specifically, a voice module can be set in the electric control box 300, and the voice module is placed in the horizontal section 320.
