[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Figure 1-3 The present application is described in detail with reference to embodiments.

[0030] The present invention provides an air conditioner indoor unit, comprising a housing 1 and a first fan 2, a heat exchanger 3, and a second fan 4 disposed within the housing 1. The housing 1 has a first air outlet 11 and a second air outlet 12. The first fan 2, the heat exchanger 3, and the second fan 4 are sequentially arranged along the direction from the first air outlet 11 to the second air outlet 12. The first fan 2 and the second fan 4 can be equal or unequal in size, and the specific fan size can be selected from the range of D76 to D106 (diameters ranging from 76 mm to 106 mm) according to the size of the housing 1. The evaporator can be selected from a double-row 2U evaporator, a triple-row 18U evaporator, a triple-row 20U evaporator, or a triple-row 22U evaporator, depending on the cooling and heating capacity requirements.

[0031] By sequentially arranging a first fan 2, a heat exchanger 3, and a second fan 4 in the housing 1, and respectively providing a first air outlet 11 corresponding to the first fan 2 and a second air outlet 12 corresponding to the second fan 4 in the housing 1, by adjusting the running directions of the first fan 2 and the second fan 4, the air flow can enter the housing 1 from the first air outlet 11 and then flow out of the housing 1 from the second air outlet 12, or enter the housing 1 from the second air outlet 12 and then flow out of the housing 1 from the first air outlet 11, and the air flow in both wind directions can exchange heat with the heat exchanger 3. According to the characteristics of the cold and hot air and the positions of the first air outlet 11 and the second air outlet 12, the above-mentioned different wind directions can be matched to different operating modes of the air conditioner indoor unit, that is, one wind direction is matched during cooling and another wind direction is matched during heating; thereby, better comfort effect and higher temperature control efficiency can be achieved during cooling and heating; furthermore, under the action of the wind force of the two fans, the air volume is large, the heat exchange efficiency is high, the temperature control efficiency is further improved, and the user experience is greatly improved. It is preferred to install the indoor unit of the air conditioner at the midpoint of the height of the indoor wall, that is, to install the shell 1 at the midpoint of the height of the wall, and to arrange the first air outlet 11 and the second air outlet 12 at the top and bottom of the shell 1 respectively. Then, during cooling, the cold air is blown upward at a height just avoiding people, and the height is not very high, so the cold air descends very quickly. During heating, the downwind outlet is close to the ground, so that the hot air can rise quickly from the ground, thereby increasing the temperature of the house.

[0032] In some embodiments of the present invention, the first air outlet 11 and the second air outlet 12 are arranged relative to each other. The relative arrangement of the first air outlet 11 and the second air outlet 12 can make the air duct from the first air outlet 11 to the second air outlet 12 a straight air duct without turning, and the air flow through this air duct is relatively smooth. Therefore, the position of the first air outlet 11 and the second air outlet 12 can increase the air flow speed and smoothness, improve the heat exchange efficiency between the air flow and the heat exchanger 3, improve the temperature control efficiency, and further improve the temperature control comfort.

[0033] In some embodiments of the present invention, the housing 1 includes a front panel, a back panel, a top panel, a bottom panel, a first side panel, and a second side panel. The top panel has an opening forming the first air outlet 11, and the bottom panel has an opening forming the second air outlet 12. The housing 1 is in a rectangular or cube shape, which facilitates the installation of the fan, heat exchanger 3, and other components within the housing 1. It also facilitates the placement of the two air outlets at the top and bottom, respectively, improving production efficiency. The internal air duct is relatively neat, facilitating airflow.

[0034] In some embodiments of the present invention, the heat exchanger 3 is a plate-type heat exchanger, and the heat exchanger 3 is tilted. The upper end of the heat exchanger 3 is connected to one of the front panel and the back panel, and the lower end of the heat exchanger 3 is connected to the other of the front panel and the back panel. The heat exchanger 3 is arranged between the two fans, enabling both top-down airflow and bottom-up airflow to pass through the heat exchanger 3 and exchange heat with them. Setting the heat exchanger 3 as a plate-type heat exchanger and tilting it between the front panel and the back panel not only allows the heat exchanger 3 to cover the entire air duct, thereby allowing all airflow passing through the duct to undergo heat exchange, but also the tilted heat exchanger 3 can increase the heat exchange area, improve the heat exchange efficiency, and enhance the heat exchange effect, thereby improving the temperature control efficiency and temperature control comfort of the air conditioner indoor unit.

[0035] In some embodiments of the present invention, a first air guide mechanism is provided between the first fan 2 and the first air outlet 11. The first air guide mechanism can direct the air blown by the first fan 2 to the first air outlet 11 or direct the air passing through the first air outlet 11 to the first fan 2. A second air guide mechanism is provided between the second fan 4 and the second air outlet 12. The second air guide mechanism can direct the air blown by the second fan 4 to the second air outlet 12 or direct the air passing through the second air outlet 12 to the second fan 4. The air guide mechanism can not only direct the airflow from inside the housing 1 to outside the housing 1, but also direct the airflow from outside the housing 1 to inside the housing 1. That is, when the air outlet corresponding to the air guide mechanism is either an air inlet or an air outlet, it can complete the air guidance, thereby improving the efficiency and flow rate of air inlet and outlet, and improving the precision of airflow direction control, further improving the accuracy and comfort of temperature control.

[0036] In some embodiments of the present invention, the first air-guiding mechanism includes a first air-duct wall close to the panel and a second air-duct wall close to the back panel, and a first inclined air-duct 5 is formed between the first air-duct wall and the second air-duct wall, and in the vertical upward direction, the first inclined air-duct 5 is inclined toward the panel; the second air-guiding mechanism includes a third air-duct wall close to the panel and a fourth air-duct wall close to the back panel, and a second inclined air-duct 6 is formed between the third air-duct wall and the fourth air-duct wall, and in the vertical downward direction, the second inclined air-duct 6 is inclined toward the panel; a second inclined air-duct 6 is formed between the two air-duct walls of the second air-guiding mechanism and the two side panels of the shell 1, and the inclined air-duct can guide the airflow in the shell 1 to be blown out toward the front of the panel. Similarly, the second inclined air-duct 6 can also guide the airflow from outside the shell 1 to inside the shell 1 in the opposite direction of the above-mentioned direction.

[0037] In some embodiments of the present invention, the first air duct wall includes a first rotating plate 51 and a first fixed plate 52, the first rotating plate 51 is rotatably connected to the top plate, one end of the first fixed plate 52 is connected to the first side plate and / or the other end of the first fixed plate 52 is connected to the second side plate, and the first rotating plate 51 can be connected to or separated from the first fixed plate 52 by rotation; the second air duct wall includes a second rotating plate 53 and a second fixed plate 54, the second rotating plate 53 is rotatably connected to the back plate, one end of the second fixed plate 54 is connected to the first side plate and / or the other end of the second fixed plate 54 is connected to the second side plate, and the second rotating plate 53 can be connected to or separated from the second fixed plate 54 by rotation;

[0038] The third air duct wall includes a third rotating plate 61 and a third fixed plate 62, the third rotating plate 61 is rotatably connected to the bottom plate, one end of the third fixed plate 62 is connected to the first side plate and / or the other end of the third fixed plate 62 is connected to the second side plate, and the third rotating plate 61 can be connected to or separated from the third fixed plate 62 by rotation; the fourth air duct wall includes a fourth rotating plate 63 and a fourth fixed plate 64, the fourth rotating plate 63 is rotatably connected to the back plate, one end of the fourth fixed plate 64 is connected to the first side plate and / or the other end of the fourth fixed plate 64 is connected to the second side plate, and the fourth rotating plate 63 can be connected to or separated from the fourth fixed plate 64 by rotation.

[0039] The first rotating plate 51 can rotate, and the second rotating plate 53 can rotate. The rotation of the first rotating plate 51 and the second rotating plate 53 can change the opening of the air duct between the first air outlet 11 and the first fan 2. That is, when the first rotating plate 51 is connected to the first fixed plate 52 and the second rotating plate 53 is connected to the second fixed plate 54, the first air outlet 11 and the first fan 2 can only be connected through the first inclined air duct 5. At this time, the first air guide mechanism can play a role in guiding the air. When the first air outlet 11 is used for exhausting air, the first rotating plate 51 and the second rotating plate 53 should be adjusted to The above-mentioned state is achieved because the wind-guiding effect of the first inclined air duct 5 can increase the outlet pressure, ensure the airflow velocity at the outlet, and increase the radiation range of the cold and warm air flows; and when the free end of the first rotating plate 51 is in contact with the panel, and the free end of the second rotating plate 53 is in contact with the back panel, the first air outlet 11 is fully connected to the first fan 2. When the first air outlet 11 is used for air intake, the first rotating plate 51 and the second rotating plate 53 should be adjusted to the above-mentioned state. At this time, the first air outlet 11 is fully connected to the first fan 2, which can increase the air intake volume.

[0040] The third rotating plate 61 can rotate, and the fourth rotating plate 63 can rotate. The rotation of the third rotating plate 61 and the fourth rotating plate 63 can change the opening of the air duct between the second air outlet 12 and the second fan 4. That is, when the third rotating plate 61 is connected to the third fixed plate 62 and the fourth rotating plate 63 is connected to the fourth fixed plate 64, the second air outlet 12 and the second fan 4 can only be connected through the second inclined air duct 6. At this time, the second air guide mechanism can play a wind guiding role. When the second air outlet 12 is used for air outlet, the third rotating plate 61 and the fourth rotating plate 63 should be adjusted When adjusted to the above state, the wind-guiding function of the second inclined air duct 6 can increase the outlet pressure, ensure the airflow velocity at the outlet, and increase the radiation range of the cold and warm air flows; and when the free end of the third rotating plate 61 is in contact with the panel, and the free end of the fourth rotating plate 63 is in contact with the back panel, the second air outlet 12 is fully connected to the second fan 4. When the second air outlet 12 is used for air intake, the third rotating plate 61 and the fourth rotating plate 63 should be adjusted to the above state. At this time, the second air outlet 12 is fully connected to the second fan 4, which can increase the air intake volume.

[0041] The first rotating plate 51, the second rotating plate 53, the third rotating plate 61 and the fourth rotating plate 63 are all connected by a pivot to achieve a rotational connection with the panel or the back panel, and the shaft in the pivot is driven by a motor or other driving member, thereby driving each rotating plate to rotate. The driving member is connected to the main control board of the air conditioner indoor unit. When the operating mode of the air conditioner indoor unit changes (such as from cooling to heating or from heating to cooling), the air inlet and outlet functions of the first air outlet 11 and the second air outlet 12 need to be switched, the main control board automatically controls the driving member to drive each rotating plate to make corresponding rotations to achieve the wind pressure of the outlet and the air volume of the inlet, thereby solving the surge problem caused by insufficient air volume in the air duct and reducing noise.

[0042] In some embodiments of the present invention, the angle between the first and second duct walls is 0-5°; the angle between the third and fourth duct walls is 0-5°. The angle between the first and second duct walls is the diffusion angle of the first inclined duct 5, and the angle between the third and fourth duct walls is the diffusion angle of the second inclined duct 6. Setting the diffusion angles of the two ducts within the above ranges ensures that the outlet air pressure is maintained when the inclined duct guides airflow out of the housing 1.

[0043] In some embodiments of the present invention, the back panel is provided with a first curved wall 7 corresponding to the first fan 2 and a second curved wall 8 corresponding to the second fan 4. The first curved wall 7 enables the air duct position corresponding to the first fan 2 to form a volute. Since the first fan 2 is preferably a cross-flow fan, the volute structure facilitates the flow of air and helps to increase the wind speed.

[0044] In some embodiments of the present invention, the minimum distance between the second fan 4 and the panel is greater than 35 mm. This distance can ensure the return air volume of the second fan 4, thereby meeting the required air volume, while also improving the air pressure stability in the air duct, solving the problem of surge in the air duct, and reducing noise generation in the air duct.

[0045] In some embodiments of the present invention, the minimum distance between the heat exchanger 3 and the first fan 2 is 30-35 mm, and the minimum distance between the heat exchanger 3 and the second fan 4 is 30-35 mm. A water tray is required below the evaporator (i.e., in the direction of the second air outlet 12) to collect condensed water. Setting the distance between the first fan 2 and the heat exchanger 3 and the distance between the second fan 4 and the heat exchanger 3 within the aforementioned ranges ensures high heat exchange efficiency when air is discharged downward (i.e., air is inletted from the first air outlet 11 and air is discharged from the second air outlet 12), and also ensures high heat exchange efficiency when air is discharged upward (i.e., air is inletted from the second air outlet 12 and air is discharged from the first air outlet 11).

[0046] When the indoor unit of the air conditioner provided by the present invention is used, it needs to be controlled according to the following process:

[0047] In cooling mode:

[0048] The first control mode: The air conditioner opens the lower air outlet (second air outlet 12) by default to discharge air, so that the temperature in the environment (such as indoors or in a car, etc.) drops and the user can feel the cool breeze. When the temperature in the environment (such as indoors or in a car, etc.) drops to the set cooling temperature threshold, the temperature sensor of the air conditioner controls the air conditioner to automatically switch to the upper air outlet (first air outlet 11) for discharge and the lower air outlet (second air outlet 12) for intake, ensuring that the cool breeze does not blow on the user.

[0049] The second control method: When the air conditioner is turned on by default, air is discharged from the lower air vent (the second air vent 12), which lowers the room temperature while the user can feel the cool breeze. When the air conditioner runs to a time threshold (5 minutes or 10 minutes, etc.), the air conditioner switches to the upper air vent (the first air vent 11) to ensure that the cool breeze does not blow to the user.

[0050] In heating mode:

[0051] By default, the air conditioner opens the downwind vent (second vent 12) to discharge air first, so that the temperature in the environment (such as indoors or in a car, etc.) increases. When it reaches the set heating temperature threshold, the air conditioner's temperature sensor controls the air conditioner to automatically switch to the upwind vent (first vent 11) to discharge air, and controls the wind speed to decrease.

[0052] Based on the same inventive concept, the present invention further provides an air conditioner comprising any one of the above-mentioned indoor units and an outdoor unit, wherein the indoor unit and the outdoor unit are interconnected to form the entire circulation loop of the air conditioner.
