Description

Technical Field

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

[0002] With the improvement of living standards, air conditioners have become one of the most commonly used household appliances, and users have put forward higher requirements for the comfort of using air conditioners. For example, in the hot summer, users often turn on the cooling mode of the air conditioner. If the cold wind blows directly on the user, the user will feel uncomfortable. Summary of the invention

[0003] The present invention provides an indoor air conditioner, which is used to solve the technical problem in the prior art that direct blowing of air conditioner leads to poor user comfort.

[0004] An air conditioner indoor unit comprises: a housing, a first air guide plate and a second air guide plate, wherein the housing has an air outlet; the upper end of the first air guide plate is pivotally connected to the upper edge of the air outlet, and the first air guide plate has a plurality of air dispersion holes; the rear end of the second air guide plate is connected to the housing;

[0005] When both the first air guide plate and the second air guide plate are in a closed state, the first air guide plate covers and closes the entire air outlet, and the second air guide plate covers and blocks the front side of the first air guide plate;

[0006] When the second air guide plate is in the anti-direct blowing open state, the wind along the air outlet direction of the air outlet all falls on the second air guide plate; the front end of the second air guide plate is located on the front side of the air outlet, and the lower end of the first air guide plate can reciprocate along the front end, inner surface and rear end of the second air guide plate in sequence.

[0007] In the indoor unit of the air conditioner provided by the present invention, on the one hand, by adopting the second air guide plate in the anti-direct blowing open state, the lower end of the first air guide plate can reciprocate between the front end, the inner surface and the rear end of the second air guide plate. If the lower end of the first air guide plate is located at the rear end of the second air guide plate, the wind is only blown out from the wind dispersion hole and is blocked and guided by the second air guide plate, which can completely prevent the air conditioner from blowing directly to the user; if the lower end of the first air guide plate moves forward along the inner surface of the second air guide plate, the first air guide plate, the second air guide plate and the shell are enclosed to form a side air outlet, and the wind is blown out from the wind dispersion outlet and the side air outlet, which can not only prevent the air conditioner from blowing directly to the user, but also The air can be discharged from the side, thereby increasing the air outlet area of ​​the air conditioner, improving the heating or cooling efficiency of the air conditioner, and meeting the different needs of users; on the other hand, the first air guide plate is pivotally connected to the upper edge of the air outlet, so that the length design and rotation of the first air guide plate are not limited by the size of the air duct, and when the lower end of the first air guide plate is located at the rear end of the second air guide plate, the wind is not blown out from the left and right ends or the upper and lower ends of the air outlet without passing through the air dispersion holes, thereby avoiding direct blowing on the user and improving the comfort of the air conditioner; in addition, when the first air guide plate and the second air guide plate are both in a closed state, the second air guide plate can completely cover the air dispersion holes of the first air guide plate, thereby preventing dust from entering the air duct through the air dispersion holes.

[0008] Furthermore, when the lower end of the first air guide plate reciprocates along the front end, inner surface and rear end of the second air guide plate in sequence, a preset gap is provided between the lower end of the first air guide plate and the inner surface of the second air guide plate. This arrangement ensures, on the one hand, that the first air guide plate does not interfere with the inner surface of the second air guide plate during its rotation, thereby preventing friction noise caused by the interference; on the other hand, the preset gap between the two reduces the processing technology and processing cost, and is easy to manufacture.

[0009] Furthermore, the preset gap is between 2mm and 5mm. This arrangement prevents the gap from being too large, causing a large amount of wind to blow out from the gap between the first air guide plate and the second air guide plate, thereby improving user comfort and achieving a wind dispersion or soft wind effect; and prevents the gap from being too small, resulting in processing technology and processing manufacturing costs.

[0010] Furthermore, the cross section of the inner surface of the second air deflector is an arc structure, and the axis of the pivot axis of the first air deflector and the housing is concentric with the center of the arc structure. With this arrangement, on the one hand, it can be ensured that during the rotation of the first air deflector, there is a preset gap between the bottom end of the first air deflector and the inner surface of the second air deflector, to prevent the gap from being too large, so that the wind blows directly to the user from the gap between the two, resulting in poor user comfort; on the other hand, the second air deflector does not need to move frequently, and the preset gap between the two is ensured by avoiding or compensating, so that the control of the second air deflector is simplified.

[0011] Further, when the second air guide plate is in the anti-direct blowing open state and the lower end of the first air guide plate is located at the rear end of the second air guide plate, the edge of the first air guide plate abuts against the lower end of the air outlet;

[0012] When the second air guide plate is in the anti-direct blowing open state and the lower end of the first air guide plate is located in the middle between the front end and the rear end of the second air guide plate, a first side air outlet is formed between the second air guide plate, the first air guide plate and the housing;

[0013] When the second air guide plate is in the anti-direct blowing open state and the lower end of the first air guide plate is located at the front end of the second air guide plate, a second side air outlet is formed between the second air guide plate, the first air guide plate and the housing;

[0014] Wherein, the area of ​​the second side air outlet is larger than the area of ​​the first side air outlet.

[0015] The air conditioner indoor unit provided by the present invention, by placing the second air guide plate in an open state to prevent direct blowing, the first air guide plate can move along the second air guide plate and be located at the front end, middle position or rear end of the second air guide plate, thereby realizing different air outlet modes, adapting to different needs of users and enhancing the practicality of the air conditioner; during the movement of the first air guide plate along the front end, middle position and rear end of the second air guide plate, the air outlet area of ​​the air conditioner increases successively, which can improve the cooling or heating efficiency of the air conditioner and at the same time can reduce the risk of condensation occurring on the first air guide plate.

[0016] Further, if the second air guide plate is in the anti-direct blowing open state, and the lower end of the first air guide plate is located at the rear end of the second air guide plate, the angle between the first air guide plate and the blocking surface is ɑ1, and the angle between the second air guide plate and the blocking surface is β1; wherein ɑ1 and β1 respectively satisfy: ɑ1 = 0° and β1 is between 45° and 55°;

[0017] If the second air guide plate is in the anti-direct blowing open state, and the lower end of the first air guide plate is located at the front end of the second air guide plate, the angle between the first air guide plate and the blocking surface is ɑ2, and the angle between the second air guide plate and the blocking surface is β2; wherein ɑ2 and β2 respectively satisfy: ɑ2 is between 45°-55° and β2 is equal to β1;

[0018] If the second air guide plate is in the anti-direct blowing open state, and the lower end of the first air guide plate is located in the middle position between the front end and the rear end of the second air guide plate, the angle between the first air guide plate and the blocking surface is ɑ3, and the angle between the second air guide plate and the blocking surface is β3; wherein ɑ3 and β3 respectively satisfy: ɑ3 is between 25°-35° and β3 is equal to β1;

[0019] Wherein, the blocking surface is the plane where the first air guide plate is located when it is in a closed state.

[0020] Furthermore, when the second air guide plate is in an open state, the lower end of the first air guide plate can be rotated forward until it is completely separated from the surface of the second air guide plate. When the second air guide plate is in a fully open state, a front air outlet is formed between the lower end of the first air guide plate and the front end of the second air guide plate. This arrangement can meet the user's demand for rapid heating.

[0021] Furthermore, if the second air guide plate is in an open state, the lower end of the first air guide plate can be rotated forward until it is completely separated from the surface of the second air guide plate. When the second air guide plate is in a fully open state, the angle between the first air guide plate and the blocking surface is ɑ4, and the angle between the second air guide plate and the blocking surface is β4; wherein ɑ4 and β4 respectively satisfy that ɑ4 is between 45°-160° and β4 is between 20°-135°. This arrangement enables both the first air guide plate and the second air guide plate to have a large rotation range, and the two cooperate to achieve a variety of air supply modes.

[0022] Furthermore, ɑ4 and β4 satisfy: ɑ4+β4=180°. In this arrangement, the first air guide plate and the second air guide plate are substantially parallel, the air guide channel formed between the two is the longest, the directional air supply distance is longer, and the indoor temperature is more uniform.

[0023] Furthermore, a rear end of the second air guide plate is pivotally connected to a lower edge of the air outlet.

[0024] The air conditioner indoor unit provided by the present invention, by arranging the pivotal positions of the second air guide plate at the lower edge of the air outlet, the length design and rotation of the second air guide plate are not restricted by the size of the air duct. When the second air guide plate is in an open state, the wind is prevented from being blown out from the left and right ends of the air outlet without being blocked by the second air guide plate, and the wind is prevented from blowing directly downwards onto the user, thereby improving the comfort of using the air conditioner.

[0025] Furthermore, the second air guide plate is slidably connected to the outer side of the shell and can extend to the front side of the air outlet.

[0026] The air conditioner indoor unit provided by the present invention arranges the sliding connection position of the second air guide plate on the outside of the shell so that the sliding of the second air guide plate is not restricted by the size of the air duct; when the second air guide plate is in an open state, the wind is prevented from being blown out from the left and right ends of the air outlet without being blocked by the second air guide plate, and the wind is prevented from blowing directly downwards toward the user, thereby improving the comfort of using the air conditioner.

[0027] Furthermore, the length of the second air guide plate is greater than that of the first air guide plate, and the length of the first air guide plate is greater than that of the air outlet. With such a configuration, on the one hand, when the bottom end of the first air guide plate 20 is located at the rear end or middle position of the second air guide plate, the wind blown out through the air dispersion hole is guided through the second air guide plate to avoid the wind blowing directly on the user, thereby improving the comfort of the air conditioner; on the other hand, when the first air guide plate and the second air guide plate are in a closed state, the second air guide plate can completely cover the air dispersion hole of the first air guide plate to prevent dust from entering the air duct through the air dispersion hole.

[0028] Furthermore, the width of the second air guide plate is greater than that of the first air guide plate, and the width of the first air guide plate is greater than that of the air outlet. With this arrangement, when the first air guide plate and the second air guide plate are in a closed state, the second air guide plate can completely cover the air holes of the first air guide plate, thereby preventing dust from entering the air duct through the air holes.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following is a brief description of the present invention in conjunction with the attached drawings. Figure 1-10 The specific embodiments of the present invention are described in detail.

[0042] In the present invention, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure.

[0043] In the present invention, terms such as "inside", "outside", "upper", "lower", "front", and "back" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0044] The embodiment of the present invention provides an indoor unit of an air conditioner. Figure 1-Figure 10 The air conditioner indoor unit comprises: a shell 10, a first air guide plate 20 and a second air guide plate 30, the shell 10 has an air outlet 101; the upper end of the first air guide plate 20 is pivotally connected to the upper edge of the air outlet 101, and the first air guide plate 20 has a plurality of air dispersion holes 201; the rear end of the second air guide plate 30 is connected to the shell 10; wherein, when the first air guide plate 20 and the second air guide plate 30 are both in a closed state, the first air guide plate 20 covers and closes the entire air outlet 101; the second air guide plate 30 covers and blocks the front side of the first air guide plate 20; when the second air guide plate 30 is in an anti-direct blowing open state, the wind along the air outlet direction of the air outlet 101 falls on the second air guide plate 30; its front end is located at the front side of the air outlet 101, and the lower end of the first air guide plate 20 can reciprocate along the front end, inner surface and rear end of the second air guide plate 30 in sequence.

[0045] It should be noted that when the second air guide plate 30 is in the anti-direct blowing open state, the lower end of the first air guide plate 20 can reciprocate between the front end, inner surface and rear end of the second air guide plate 30, and the first air guide plate 20, the second air guide plate 30 and the shell 10 will enclose to form a side air outlet connected to the air outlet 101; when the second air guide plate 30 is in the anti-direct blowing open state, the wind along the air outlet direction of the air outlet 101 falls on the second air guide plate 30, preventing part of the wind along the air outlet direction of the air outlet 101 from blowing directly downwards to the user without being blocked by the second air guide plate 30.

[0046] It should be noted that the upper end of the first air guide plate 20 is pivotally connected to the upper edge of the air outlet 101, that is, the upper end of the first air guide plate 20 is not pivotally connected to the air duct, so that the length of the first air guide plate 20 and the rotation of the first air guide plate 20 are not limited by the size of the air duct; if the first air guide plate 20 is in a closed state, the first air guide plate 20 can fully block the front side of the air outlet 101, avoiding the wind at the left and right ends of the air outlet 101 or the wind at the upper and lower ends of the air outlet 101 from blowing directly to the user without passing through the air dispersion holes 201, thereby improving the comfort of using the air conditioner.

[0047] It should be noted that when the first air guide plate 20 and the second air guide plate 30 are both in the closed state, the first air guide plate 20 covers and closes the entire air outlet 101; the second air guide plate 30 covers and blocks the front side of the first air guide plate 20; the second air guide plate 30 can completely cover the air dispersion holes 201 of the first air guide plate 20 to prevent dust from entering the air duct through the air dispersion holes 201.

[0048] Therefore, the air conditioner indoor unit provided by the embodiment of the present invention, on the one hand, by adopting that when the second air guide plate 30 is in the anti-direct blowing open state, the lower end of the first air guide plate 20 can reciprocate between the front end, the inner surface and the rear end of the second air guide plate 30. If the lower end of the first air guide plate 20 is located at the rear end of the second air guide plate 30, the wind is only blown out from the wind dispersion hole 201 and guided by the shielding of the second air guide plate 30, which can completely prevent the air conditioner from blowing directly to the user; if the lower end of the first air guide plate 20 moves forward along the inner surface of the second air guide plate 30, the first air guide plate 20, the second air guide plate 30 and the shell 10 are enclosed to form a side air outlet, and the wind is blown out from the wind dispersion hole 201 and the side air outlet, which can not only prevent the air conditioner from blowing directly to the user, The air can also be discharged from the side, thereby increasing the air outlet area of ​​the air conditioner, improving the heating or cooling efficiency of the air conditioner, and meeting the different needs of users. On the other hand, the first air guide plate 20 is pivotally connected to the upper edge of the air outlet 101, so that the length design and rotation of the first air guide plate 20 are not limited by the size of the air duct, thereby preventing the wind from being blown out from the left and right ends or the upper and lower ends of the air outlet 101 without passing through the air dispersion holes 201 when the lower end of the first air guide plate 20 is located at the rear end of the second air guide plate 30, thereby preventing the wind from being blown directly onto the user and improving the comfort of using the air conditioner. In addition, when the first air guide plate 20 and the second air guide plate 30 are both in a closed state, the second air guide plate 30 can completely cover the air dispersion holes 201 of the first air guide plate 20, thereby preventing dust from entering the air duct through the air dispersion holes 201.

[0049] In the embodiment of the present invention, the lower end of the first air guide plate 20 reciprocates along the front end, inner surface and rear end of the second air guide plate 30 in sequence, and a preset gap is provided between the lower end of the first air guide plate 20 and the inner surface of the second air guide plate 30. This arrangement ensures, on the one hand, that the first air guide plate 20 does not interfere with the inner surface of the second air guide plate 30 during the rotation process, thereby preventing friction noise caused by the interference; on the other hand, the preset gap between the two reduces the processing technology and processing cost, and is easy to manufacture.

[0050] In the embodiment of the present invention, the preset gap is between 2mm and 5mm. This configuration prevents the gap from being too large, causing a large amount of wind to blow out from the gap between the first air guide plate 20 and the second air guide plate 30, thereby improving the user's comfort and achieving a wind dispersion or soft wind effect; and prevents the gap from being too small, resulting in processing technology and processing manufacturing costs.

[0051] In the embodiment of the present invention, preferably, the cross section of the inner surface of the second air guide plate 30 is an arc structure, and the axis of the pivot axis of the first air guide plate 20 and the housing 10 is concentric with the center of the arc structure. With such a configuration, on the one hand, it can be ensured that during the rotation of the first air guide plate 20, there is a preset gap between the bottom end of the first air guide plate 20 and the inner surface of the second air guide plate 30, so as to prevent the gap from being too large, causing the wind to blow directly to the user from the gap between the two, resulting in poor user comfort; on the other hand, the second air guide plate 30 does not need to move frequently, and the preset gap between the two is ensured by avoiding or compensating, so that the control of the second air guide plate 30 is simplified.

[0052] See attached Figure 1-Figure 6 In the embodiment of the present invention, when the second air guide plate 30 is in the anti-direct blowing open state and the lower end of the first air guide plate 20 is located at the rear end of the second air guide plate 30, the edge of the first air guide plate 20 abuts against the lower end of the air outlet 101, and the air conditioner has a first air outlet mode; when the second air guide plate 30 is in the anti-direct blowing open state and the lower end of the first air guide plate 20 is located at the middle position between the front end and the rear end of the second air guide plate 30, a first side air outlet 102 is formed between the second air guide plate 30, the first air guide plate 20 and the shell 10, and the air conditioner has a second air outlet mode; when the second air guide plate 30 is in the anti-direct blowing open state and the lower end of the first air guide plate 20 is located at the front end of the second air guide plate 30, a second side air outlet 103 is formed between the second air guide plate 30, the first air guide plate 20 and the shell 10, and the air conditioner has a third air outlet mode; wherein the area of ​​the second side air outlet 103 is greater than the area of ​​the first side air outlet 102.

[0053] It should be noted that when the air conditioner is in the first air outlet mode, the wind is blown out only from the air dispersion holes 201, and the second air guide plate 30 guides the wind forward or upward to prevent the wind from blowing directly downward on the user, thereby improving the user's comfort; when the air conditioner is in the second air outlet mode, the wind is blown out from the air dispersion holes 201 and the first side air outlet 102, thereby increasing the air outlet area, improving the cooling or heating efficiency of the air conditioner, and reducing the risk of condensation on the first air guide plate 20; since the lower end of the first air guide plate 20 is located in the middle position between the front end and the rear end of the second air guide plate and has a preset gap, the wind blown out from the air dispersion holes 201 will be further guided by the second air guide plate 30 to prevent the wind from blowing downward; when the air conditioner is in the third air outlet mode, the wind is blown out from the air dispersion holes 201 and the second side air outlet 103, further increasing the air outlet area, improving the cooling or heating efficiency of the air conditioner, and reducing the risk of condensation on the first air guide plate 20.

[0054] Therefore, the air-conditioning indoor unit provided by the embodiment of the present invention, by putting the second air guide plate 30 in the anti-direct blowing open state, the first air guide plate 20 can move along the second air guide plate 30, and be located at the front end, middle position or rear end of the second air guide plate 30, to achieve different air outlet modes, adapt to the different needs of users, and enhance the practicality of the air conditioner; during the movement of the first air guide plate 20 along the front end, middle position and rear end of the second air guide plate 30, the air outlet area of ​​the air conditioner increases successively, which can improve the cooling or heating efficiency of the air conditioner, and at the same time can also reduce the risk of condensation on the first air guide plate 20.

[0055] See attached Figure 2 In the embodiment of the present invention, if the second air guide plate 30 is in the anti-direct blowing open state, and the lower end of the first air guide plate 20 is located at the rear end of the second air guide plate 30, the angle between the first air guide plate 20 and the blocking surface A is ɑ1, and the angle between the second air guide plate 30 and the blocking surface A is β1; wherein ɑ1 and β1 respectively satisfy: ɑ1 = 0° and β1 is between 45°-55°; the blocking surface A is the plane where the first air guide plate 20 is located when it is in the closed state. In this way, the wind blown out through the air dispersion hole 201 is blocked by the second air guide plate 30, and the wind direction is changed to prevent the wind from blowing directly on the user.

[0056] It should be noted that since the first air guide plate 20 can be a flat structure or a curved structure, if the first air guide plate 20 is a flat structure, the blocking surface A is the plane where the first air guide plate 20 is in a closed state, that is, the plane where the upper and lower edges of the first air guide plate 20 are located; if the first air guide plate 20 is a curved structure, the blocking surface A is the same plane where the upper and lower edges of the first air guide plate 20 are located.

[0057] See attached Figure 4 In an embodiment of the present invention, if the second air guide plate 30 is in the anti-direct blowing open state and the lower end of the first air guide plate 20 is located at the front end of the second air guide plate 30, the angle between the first air guide plate 20 and the blocking surface A is ɑ2, and the angle between the second air guide plate 30 and the blocking surface A is β2; wherein ɑ2 and β2 respectively satisfy: ɑ2 is between 45°-55° and β2 is equal to β1.

[0058] See attached Figure 6 In an embodiment of the present invention, if the second air guide plate 30 is in the anti-direct blowing open state, and the lower end of the first air guide plate 20 is located in the middle position between the front end and the rear end of the second air guide plate 30, the angle between the first air guide plate 20 and the blocking surface A is ɑ3, and the angle between the second air guide plate 30 and the blocking surface A is β3; wherein ɑ3 and β3 respectively satisfy: ɑ3 is between 25°-35° and β3 is equal to β1.

[0059] See attached Figure 7-Figure 8In the embodiment of the present invention, the second air guide plate 30 is in an open state, and the lower end of the first air guide plate 20 can be rotated forward until it is completely separated from the surface of the second air guide plate 30. When the air guide plate 20 is in a fully open state, a front air outlet is formed between the lower end of the first air guide plate 20 and the front end of the second air guide plate 30, and the air conditioner has a normal air outlet mode. Such a setting can meet the user's needs for rapid heating or cooling.

[0060] It should be noted that the second air guide plate 30 is in the open state, which may be the second air guide plate 30 is in the open state for preventing direct blowing, or the second air guide plate 30 is in the open state for direct blowing.

[0061] See attached Figure 8 In the embodiment of the present invention, if the second air guide plate 30 is in an open state, the lower end of the first air guide plate 20 can be rotated forward until it is completely separated from the surface of the second air guide plate 30. When the surface is in a fully open state, the angle between the first air guide plate 20 and the blocking surface A is ɑ4, and the angle between the second air guide plate 30 and the blocking surface A is β4; wherein ɑ4 and β4 respectively satisfy that ɑ4 is between 45°-160° and β4 is between 20°-135°. With such a configuration, the direction and air outlet area of ​​the front air outlet can be changed, the air supply distance can be increased, and the different needs of users can be met to achieve rapid heating or cooling.

[0062] In the embodiment of the present invention, ɑ4 and β4 satisfy: ɑ4+β4=180°. This arrangement makes the first air guide plate 20 and the second air guide plate 30 substantially parallel, the air guide channel formed between the two is the longest, the directional air supply distance is longer, and the indoor temperature is more uniform.

[0063] See attached Figure 1-Figure 10 In one implementation of the embodiment of the present invention, a rear end of the second air guide plate 30 is pivotally connected to a lower edge of the air outlet 101 .

[0064] It should be noted that the rear end of the second air guide plate 30 is pivotally connected to the lower edge of the air outlet 101, that is, the rear end of the second air guide plate 30 is not pivotally connected to the air duct, so that the length of the second air guide plate 30 and the rotation of the second air guide plate 30 are not limited by the size of the air duct; if the second air guide plate 30 opens the air outlet 101 and the front end of the second air guide plate 30 is located in front of the air outlet 101, when the lower end of the first air guide plate 20 is close to or close to the inner surface of the second air guide plate 30, the second air guide plate 30 guides the wind blown out of the air dispersion holes 201 to avoid the wind blowing directly on the user, thereby improving the comfort of using the air conditioner.

[0065] It should be noted that the blocking surface A refers to the plane where the axis of the pivotal axis between the first air guide plate 20 and the upper edge of the air outlet 101 and the axis of the pivotal axis between the second air guide plate 30 and the lower edge of the air outlet 101 are located.
