Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology
[0002] An air conditioner's indoor unit includes a main air duct. Indoor air enters through the main air duct's inlet, exchanges heat with the heat exchanger, and then exits as a heated airflow from the main air duct's outlet. When the heated airflow is cooling, the cooled airflow blown directly onto the user can cause discomfort and a feeling that the airflow is too harsh. To avoid user discomfort, the air conditioner's indoor unit also includes a side air duct. The side air duct's inlet connects to the indoor air, and its outlet connects to the main air duct. In this way, indoor air enters through the side air duct and mixes with the heated airflow in the main air duct before being blown out, making the blown airflow closer to the indoor ambient temperature. Existing technologies typically include a control valve in the side air duct to prevent reverse airflow. However, the control valve has a complex structure and is prone to wear and failure over long-term use. Utility Model Content

[0014] The second wind-blocking surface is the surface of the second air guide block facing the outlet of the first air duct; along the first direction, the distance between part or all of the second wind-blocking surface and the outlet gradually increases.
[0015] Optionally, there are multiple first air guide blocks and second air guide blocks, which are arranged alternately in the first air duct along the flow direction of the airflow.
[0016] Optionally, the first air guide block is located on one side of the center surface of the first air duct, and the second air guide block is located on the other side of the center surface;
[0017] The minimum distance from the first air guide block to the center surface is 1 / 30 to 1 / 10 of the width of the first air duct;
[0018] The minimum distance from the second air guide block to the center surface is 1 / 30 to 1 / 10 of the width of the first air duct.
[0019] Optionally, the ratio between the distance between the same position on two adjacent first air guide blocks and the width of the first air duct is 1.4 to 1.7;
[0020] The ratio between the distance between the same position on two adjacent second air guide blocks and the width of the first air duct is 1.4 to 1.7.
[0021] Optionally, along the flow direction of the airflow in the first air duct, the distance between each first air guide block and the second air guide blocks on both sides thereis not equal;
[0022] Multiple first air guide blocks are arranged at equal intervals, and multiple second air guide blocks are arranged at equal intervals.
[0023] Optionally, the first air guide surface is an inclined surface, and the angle between the first air guide surface and the side wall connected thereto is 45° to 55°.
[0024] The second air guide surface is an inclined surface, and the angle between the second air guide surface and the side wall connected to it is 45° to 55°.
[0025] Both the first and second wind-blocking surfaces are arc-shaped surfaces, with a central angle of 70° to 75° and a ratio between the radius of the arc-shaped surface and the width of the first air duct of 3 / 10 to 2 / 5.
[0026] Along the flow direction of the airflow in the first air duct, one end of the arc-shaped surface connected to the side wall of the air duct is located downstream of the other end.
[0027] Optionally, a second air duct is also provided inside the housing, and a heat exchanger and a fan are provided inside the second air duct;
[0028] The outlet of the first air duct is located on the side wall of the second air duct, and the outlet of the first air duct is located on the air outlet side of the fan.
[0029] Optionally, the housing is provided with an air outlet and an air inlet communicating with the second air duct.
[0030] The second air duct is equipped with an air outlet vane, and the outlet of the first air duct is located on the air outlet side of the air outlet vane.
[0031] An air guide plate is installed at the air outlet.
[0032] Optionally, the housing is arranged vertically, and the inlet of the first air duct is located on the housing;
[0033] The air outlet, the inlet of the first air duct, and the outlet of the first air duct all extend in a vertical direction.
[0034] The inlet of the first air duct is equipped with a filter device.
[0035] In the indoor unit of this air conditioner, airflow enters from the inlet of the first air duct and exits from the outlet of the first air duct. Along a first direction, the distance between the first air guide surface and the inlet gradually increases, ensuring that during airflow outflow, the first air guide surface facilitates the airflow entering from the inlet of the first air duct and exiting from the outlet. When the airflow reverses direction, it enters from the outlet of the first air duct, and along a second direction opposite to the first direction, the distance between part or all of the first air-blocking surface and the outlet gradually increases, causing the first air-blocking surface to impede the reverse airflow. The airflow flowing towards the first air-blocking surface changes direction under its guidance and cannot flow towards the inlet of the first air duct, thus restricting the airflow direction. In other words, by setting a first air guide block within the first air duct to restrict the airflow direction, no moving parts or control components are required, resulting in wear-free operation and a long service life.
[0036] Furthermore, in the indoor unit of the air conditioner of this invention, airflow enters from the inlet of the first air duct and exits from the outlet of the first air duct. During the airflow outflow process, the second air guide surface also helps to guide the airflow from the inlet of the first air duct to the outlet of the first air duct. When the airflow reverses direction, the airflow enters from the outlet of the first air duct, and the second air-blocking surface also plays the role of preventing the airflow from reversing. The airflow flowing towards the second air-blocking surface changes direction under the guidance of the second air-blocking surface and cannot flow towards the inlet of the first air duct, thereby restricting the airflow direction. In other words, by setting a second air guide block in the first air duct, the airflow direction can also be restricted, without the need for moving parts and control parts, and has the characteristics of no wear and long service life. Moreover, the cooperation between the second air guide block and the first air guide block enhances the effect of guiding and blocking airflow.

[0045] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figure 2 ,exist Figure 2In the diagram, the arrows indicate the airflow direction. This embodiment of the invention provides an indoor unit for an air conditioner, including a housing 10 and at least one first air guide block 200. A first air duct 100 is disposed within the housing 10, and at least one first air guide block 200 is disposed on one side wall of the first air duct 100. Each first air guide block 200 includes a first air guiding surface 210 and a first air blocking surface 220. The first air guiding surface 210 is the surface of the first air guide block 200 facing the inlet 110 of the first air duct 100. Along a first direction, the distance between the first air guiding surface 210 and the inlet gradually increases. The first direction is the direction from one side wall of the first air duct 100 to another side wall. The first air blocking surface 220 is the surface of the first air guide block 200 facing the outlet of the first air duct 100. Along a second direction opposite to the first direction, the distance between part or all of the first air blocking surface 220 and the outlet gradually increases.
[0046] In this embodiment, airflow enters from the inlet of the first air duct 100 and exits from the outlet of the first air duct 100. Along the first direction, the distance between the first guide surface 210 and the inlet 110 gradually increases, thereby ensuring that during the airflow outflow, the first guide surface 210 facilitates the airflow entering from the inlet 110 of the first air duct 100 and exiting from the outlet of the first air duct 100. When the airflow reverses direction, it enters from the outlet 120 of the first air duct 100. Along the second direction opposite to the first direction, the distance between part or all of the first obstructing surface 220 and the outlet gradually increases, causing the first obstructing surface 220 to impede the reverse airflow. Figure 2 As shown, the airflow towards the first wind-blocking surface 220 changes direction under the guidance of the first wind-blocking surface 220 and cannot flow towards the inlet 110 of the first air duct, thus restricting the airflow direction. In other words, by setting the first air guide block in the first air duct to restrict the airflow direction, no moving parts or control parts are required, and it has the characteristics of no wear and long service life.
[0047] In some embodiments of this utility model, the indoor unit of the air conditioner further includes at least one second air guide block 300. At least one second air guide block 300 is disposed on another side wall of the first air duct 100. Each second air guide block 300 includes a second air guiding surface 310 and a second air blocking surface 320. The second air guiding surface 310 is the surface of the second air guide block 300 facing the inlet 110 of the first air duct 100. Along a second direction, the distance between the second air guiding surface 310 and the inlet gradually increases. The second air blocking surface 320 is the surface of the second air guide block 300 facing the outlet 120 of the first air duct 100. Along a first direction, the distance between part or all of the second air blocking surface 320 and the outlet 120 gradually increases.
[0048] In this embodiment, the airflow enters from the inlet 110 of the first air duct 100 and exits from the outlet 120 of the first air duct 100. During the airflow exit, the second guide surface 310 also helps guide the airflow from the inlet of the first air duct 100 to the outlet of the first air duct 100. When the airflow reverses direction, it enters from the outlet of the first air duct 100, and the second obstructive surface 320 similarly hinders the reverse airflow. Figure 2 As shown, the airflow towards the second air-blocking surface changes direction under its guidance and cannot flow towards the inlet of the first air duct, thus restricting the airflow direction. In other words, by setting a second guide block within the first air duct, the airflow direction can also be restricted. This eliminates the need for moving or control components, resulting in wear-free operation and a long service life. Furthermore, the cooperation between the second and first guide blocks enhances both the guiding and blocking effects of the airflow.
[0049] In some embodiments of this utility model, such as Figure 2 As shown, there are multiple first guide blocks 200 and multiple second guide blocks 300. Along the airflow direction within the first air duct 100, the first guide blocks 200 and multiple second guide blocks 300 are alternately arranged sequentially within the first air duct 100. When the airflow flows from the inlet to the outlet, the multiple first guide blocks 200 and multiple second guide blocks 300 effectively guide the airflow along the length and width of the entire air duct, resulting in a stronger guiding effect. When the airflow reverses direction, entering from the outlet of the first air duct 100 and flowing towards the inlet, the multiple first guide blocks 200 and multiple second guide blocks 300 similarly hinder the reverse flow of airflow.
[0050] In some embodiments of this utility model, such as Figure 2 As shown, the first air guide block 200 is located on one side of the center plane of the first air duct 100, and the second air guide block 300 is located on the other side of the center plane. The minimum distance from the first air guide block 200 to the center plane is 1 / 30 to 1 / 10 of the width of the first air duct 100. The minimum distance from the second air guide block 300 to the center plane is 1 / 30 to 1 / 10 of the width of the first air duct 100.
[0051] In this embodiment, by limiting the first air guide block 200 and the second air guide block 300, the first air guide block 200 and the second air guide block 300 will not reduce the airflow in the air duct, and can play a certain guiding or blocking role.
[0052] In some embodiments of this utility model, such as Figure 2As shown, the ratio of the distance between the same position on two adjacent first air guide blocks 200 to the width of the first air duct 100 is 1.4 to 1.7. The ratio of the distance between the same position on two adjacent second air guide blocks 300 to the width of the first air duct 100 is also 1.4 to 1.7. In these embodiments, the distance between two adjacent first air guide blocks 200 is greater than the width of the first air duct 100 to avoid the first air guide blocks 200 being arranged too densely along the length of the first air duct 100, thus affecting the air guiding effect. Similarly, the distance between two adjacent second air guide blocks 300 is greater than the width of the first air duct 100 to avoid the second air guide blocks 300 being arranged too densely along the length of the first air duct 100, thus affecting the air guiding effect.
[0053] In some embodiments of this utility model, such as Figure 2 As shown, along the airflow direction within the first air duct 100, the distances between each first air guide block 200 and the second air guide blocks 300 on either side thereof are not equal. Multiple first air guide blocks 200 are arranged at equal intervals, and multiple second air guide blocks 300 are arranged at equal intervals.
[0054] Of course, in some other embodiments of this utility model, along the flow direction of the airflow in the first air duct 100, the distance between each first air guide block 200 and the second air guide blocks 300 on both sides thereis is equal.
[0055] In some embodiments of this utility model, such as Figure 2 As shown, the first air guide surface 210 is an inclined surface, and the angle between the first air guide surface 210 and the side wall connected to it is 45° to 55°. The second air guide surface 310 is an inclined surface, and the angle between the second air guide surface 310 and the side wall connected to it is 45° to 55°. Both the first air blocking surface 220 and the second air blocking surface 320 are arc-shaped surfaces, with a central angle of 70° to 75°, and the ratio between the radius of the arc-shaped surface and the width of the first air duct 100 is 3 / 10 to 2 / 5. Along the flow direction of the airflow within the first air duct 100, one end of the arc-shaped surface connected to the side wall of the air duct is downstream of the other end.
[0056] The first guide surface 210 guides airflow along its surface, and the second guide surface 310 guides airflow along its surface. Airflow passing through the first guide surface 210 is directed towards the downstream second guide surface 310, which then guides this airflow towards the downstream first guide surface 210, thus gradually guiding the airflow through the first air duct 100. The arc shape of the first and second obstructing surfaces 220 prevents airflow from flowing out from the outlet to the inlet of the first air duct 100. Figure 2As shown, the airflow direction of the airflow passing through the arc-shaped surfaces of the first wind-blocking surface 220 and the second wind-blocking surface 320 changes to the direction towards the outlet of the first air duct, thereby preventing the airflow from flowing from the outlet of the first air duct to the inlet of the first air duct.
[0057] In some embodiments of this utility model, such as Figure 1 As shown, a second air duct 400 is also provided inside the housing 10, and a heat exchanger 500 and a fan 600 are provided inside the second air duct 400. The outlet of the first air duct 100 is located on the side wall of the second air duct 400, and the outlet of the first air duct 100 is located on the air outlet side of the fan 600.
[0058] The fan 600 is typically a centrifugal fan or a cross-flow fan. It generates negative pressure through impeller rotation, guiding airflow steadily into the second air duct. The intake air flows through the heat exchanger 500, exchanging heat with it, and then flows along the second air duct 400 under the guidance of the fan 600. The second air duct 400 is used to blow out the heat-exchange airflow. The airflow velocity on the outlet side of the fan 600 is faster, and the negative pressure generated during flow is greater, which helps to draw more airflow from the inlet of the first air duct 100 and mix it with the heat-exchange airflow in the second air duct 400. Especially when the second air duct 400 blows out cooling airflow, the indoor air entering from the inlet of the first air duct 100 mixes with the cooling airflow in the second air duct 400, making the airflow blowing out from the second air duct 400 closer to room temperature and less harsh on the user.
[0059] In some embodiments of this utility model, the housing 10 is provided with an air outlet 101 and an air inlet 102 that communicate with the second air duct 400, and an air outlet vane 700 is provided inside the second air duct 400, with the outlet of the first air duct 100 located on the air outlet side of the air outlet vane 700.
[0060] Airflow enters the second air duct 400 through the air inlet connected to the second air duct 400 and exits through the air outlet connected to the second air duct 400. The air outlet vane 700 can guide the airflow upwards or downwards. When the air outlet vane 700 swings upwards, the airflow passing through it flows obliquely upwards. When the air outlet vane 700 swings downwards, the airflow passing through it flows obliquely downwards. Furthermore, the outlet of the first air duct 100 is located on the air outlet side of the air outlet vane 700. The airflow passing through the first air duct 100 mixes with the heating airflow guided by the air outlet vane 700 and is then blown out of the air outlet of the second air duct 400.
[0061] In some embodiments of this utility model, the air inlet 102 of the second air duct 400 is located on the rear wall of the housing and the side wall connected to the rear wall, thereby making the air inlet 102 of the second air duct 400 have sufficient width, which is conducive to the entry of indoor air.
[0062] In some embodiments of this utility model, such as Figure 1 As shown, an air guide plate 800 is installed at the air outlet. The air guide plate 800 is used to guide the lateral direction of the airflow blowing out of the air outlet of the second air duct 400. When the air guide plate 800 is tilted to the right, the airflow blowing out of the air outlet of the second air duct 400 blows to the right. When the air guide plate 800 is tilted to the left, the airflow blowing out of the air outlet of the second air duct 400 blows to the left. The guiding effect of the air guide plate 800 on the airflow also reduces the collision between the airflow and the edge of the air outlet, suppressing eddy noise. When the air guide plate 800 is in the closed state, it can also prevent dust, insects and other foreign objects from entering the equipment.
[0063] In some embodiments of this utility model, the air guide plate 800 includes a first air guide plate and a second air guide plate. The first air guide plate and the second air guide plate are arranged sequentially along the transverse direction of the air outlet of the second air duct.
[0064] The first and second air guide vanes can be opened or closed simultaneously to correspondingly open or close the air outlet of the entire second air duct. The first and second air guide vanes can also be rotated at a certain angle to guide the flow direction of the airflow laterally.
[0065] In some embodiments of this utility model, the housing 10 is vertically oriented, and the inlet of the first air duct 100 is located on the housing 10. The air outlet 101, the inlet 110 of the first air duct 100, and the outlet 120 of the first air duct 100 all extend vertically. The vertically oriented air outlet 101 facilitates the uniform vertical airflow from the indoor unit of the air conditioner, rapidly adjusting the indoor temperature and preventing temperature stratification. The vertical extension of the inlet 110 and outlet 120 of the first air duct 100 facilitates the mixing of the airflow from the first air duct with the airflow from the second air duct.
[0066] In some embodiments of this utility model, a filter device is provided at the inlet 110 of the first air duct 100. The filter device can intercept particulate pollutants such as dust, pollen, and hair in the air, purify the air entering the first air duct, and prevent impurities from entering the interior of the first air duct.
[0067] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
