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 air-conditioning indoor unit, which is used to solve the technical problem in the prior art that direct blowing of air-conditioning leads to poor user comfort.

[0004] The present invention provides an air conditioner indoor unit, comprising: 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] The indoor unit of the air conditioner has a first zero wind mode and a second zero wind mode;

[0006] The first zero wind mode is configured as follows: the first air guide plate covers and closes the entire air outlet, the second air guide plate opens the air outlet, and the front end of the second air guide plate is located at the front side of the air outlet;

[0007] The second zero wind mode is configured as follows: the lower end of the first air guide plate and the front end of the second air guide plate are both located on the front side of the air outlet, and the lower end of the first air guide plate is close to or closely attached to the middle position between the front end and the rear end of the second air guide plate, and the first air guide plate, the second air guide plate and the shell together form a first side air outlet.

[0008] The air-conditioning indoor unit provided by the present invention realizes different zero-wind modes by adjusting the positional relationship between the first air guide plate and the second air guide plate. On the first aspect, it can prevent wind from blowing directly downward on the user, thereby improving the user's comfort; on the second aspect, the air outlet positions and air outlet areas of the first zero-wind mode and the second zero-wind mode are different, and the heating or cooling efficiencies are different, which can adapt to the different needs of users and enhance the practicality of the air conditioner; on the third aspect, the pivotal position of the first air guide plate is set at the upper edge of the air outlet, so that the length design and rotation of the first air guide plate are not restricted by the size of the air duct, thereby preventing wind from blowing out from the left and right ends or the upper and lower ends of the air outlet without passing through the air dispersion holes in the first zero-wind mode, thereby preventing wind from blowing directly on the user and improving the comfort of use of the air conditioner; in addition, the lower end of the first air guide plate is close to or close to the inner surface of the second air guide plate, thereby improving the wind dispersion or soft wind effect.

[0009] Furthermore, if the air conditioner indoor unit is in the first zero wind mode, 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°; the blocking surface is the plane where the first air guide plate is located when the air outlet is closed. In this way, the wind blown out through the air diffuser hole is blocked by the second air guide plate, changing the wind outlet direction to prevent the wind from blowing directly on the user.

[0010] Furthermore, if the air conditioner indoor unit is in the second zero wind mode, 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 25°-35° and β2 is between 55°-65°. This arrangement can ensure that the bottom end of the first air guide plate is close to or close to the inner surface of the second air guide plate, avoiding an excessively large gap between the bottom end of the first air guide plate and the second air guide plate, causing wind to blow out of the gap, thereby weakening the effect of dispersing or softening the wind.

[0011] Furthermore, the air conditioner indoor unit also has a conventional air outlet mode;

[0012] The conventional air outlet mode is configured as follows: the first air guide plate and the second air guide plate both open the air outlet, and 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 configuration can meet the user's needs for rapid heating or cooling.

[0013] Furthermore, if the air conditioner indoor unit is in the conventional air outlet mode, 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: ɑ4 is between 45°-160° and β4 is between 20°-135°. With such a setting, the direction and air outlet area of ​​the front air outlet can be changed, the air supply distance can be increased, the different needs of users can be met, and rapid heating or cooling can be achieved; the first air guide plate and the second air guide plate both have a large rotation range, and the two cooperate to achieve a variety of air supply modes.

[0014] 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.

[0015] Furthermore, the air conditioner indoor unit also has a closed mode;

[0016] The closed mode is configured as follows: the first air guide plate and the second air guide plate both close the outlet, and the second air guide plate blocks the air dispersion hole. In this configuration, when the first air guide plate and the second air guide plate are in the 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.

[0017] Furthermore, a rear end of the second air guide plate is pivotally connected to a lower edge of the air outlet.

[0018] 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 respectively, so that the length design and rotation of the second air guide plate are not restricted by the size of the air duct, thereby preventing the wind from being blown out from the left and right ends of the air outlet without being blocked by the second air guide plate in the first zero wind mode, preventing the wind from blowing directly downwards on the user, and improving the comfort of using the air conditioner.

[0019] Furthermore, the second air guide plate is slidably connected to the shell and can extend to the front side of the air outlet.

[0020] The air conditioner indoor unit provided by the present invention sets 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; thus, in the first zero wind mode, it is avoided that the wind is blown out from the left and right ends of the air outlet without being blocked by the second air guide plate, thereby avoiding the wind from blowing directly downwards on the user, thereby improving the comfort of using the air conditioner.

[0021] Furthermore, the second air guide plate is pivotally connected to a first slider, and the first slider is slidably connected to the shell.

[0022] Furthermore, the shell includes an end cover, the end cover is provided with an arc-shaped slideway, and the first sliding block is slidably connected to the arc-shaped slideway.

[0023] 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, in the first zero-wind mode, the wind blown out through the air dispersion holes is guided through the second air guide plate to prevent the wind from blowing directly on the user, thereby improving the comfort of using the air conditioner; on the other hand, in the second zero-wind mode, the wind from the air outlet is prevented from blowing directly on the user without being blocked by the second air guide plate, thereby improving the comfort of using the air conditioner; in addition, 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 holes of the first air guide plate, thereby preventing dust from entering the air duct through the air dispersion holes.

[0024] 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.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following Figure 1-10 The specific embodiments of the present invention are described in detail.

[0038] 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.

[0039] 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 cannot be understood as a limitation on the present invention.

[0040] The embodiment of the present invention provides an indoor unit of an air conditioner. Figure 1-Figure 4 The air conditioner indoor unit comprises: a housing 10, a first air guide plate 20 and a second air guide plate 30, the housing 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 housing 10; the air conditioner indoor unit has a first zero wind mode and a second zero wind mode; wherein the first zero wind mode is configured as follows: the first air guide plate 20 covers and closes the entire air outlet 101, and the second air guide plate 30 opens the air outlet 101 1 and the front end of the second air guide plate 30 is located in front of the air outlet 101, and the wind is blown out only from the wind dispersion hole 201; the second zero wind mode is configured as follows: the lower end of the first air guide plate 20 and the front end of the second air guide plate 30 are both located in front of the air outlet 101, and the lower end of the first air guide plate 20 is close to or closely attached to the middle position between the front end and the rear end of the second air guide plate 30, the first air guide plate 20, the second air guide plate 30 and the shell 10 enclose a first side air outlet 102, and the wind is blown out from the wind dispersion hole 201 and the first side air outlet 102.

[0041] It should be noted that when the air conditioner is in the first zero wind mode, the wind is only blown out from the wind dispersion holes 201, and the front end of the second wind guide plate 30 is located in front of the air outlet 101, and the second wind guide plate 30 guides the wind forward or upward to avoid the wind blowing directly downward on the user, thereby improving the user's comfort; when the air conditioner is in the second zero wind mode, on the one hand, the wind is blown out from the wind 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 wind guide plate 20; on the other hand, because the lower end of the first wind guide plate 20 is close to or close to the middle position between the front end and the rear end of the second wind guide plate 30, the wind blown out through the wind dispersion holes 201 is further guided forward or upward by the second wind guide plate 30, thereby avoiding the wind blowing directly downward on the user.

[0042] 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.

[0043] It should be noted that when the air conditioner is in the first zero wind mode, the lower end of the first air guide plate 20 is close to or in close contact with the rear end of the second air guide plate 30; wherein, the lower end of the first air guide plate 20 is close to the rear end of the second air guide plate 30, that is, there is a gap between the lower end of the first air guide plate 20 and the front end of the second air guide plate 30, and the gap is less than or equal to 5mm. When the air conditioner is in the second zero wind mode, the lower end of the first air guide plate 20 is close to or in close contact with the middle position between the front end and the rear end of the second air guide plate 30; wherein, the lower end of the first air guide plate 20 is close to the middle position between the front end and the rear end of the second air guide plate 30, that is, there is a gap between the lower end of the first air guide plate 20 and the middle position of the second air guide plate 30, and the gap is less than or equal to 5mm. This arrangement prevents the gap between the lower end of the first air guide plate 20 and the inner surface of the second air guide plate 30 from being too large, causing the wind to blow out from the gap between the two, affecting the wind dispersion or soft wind effect.

[0044] Therefore, the air-conditioning indoor unit provided in the embodiment of the present invention realizes different zero-wind modes by adjusting the positional relationship between the first air guide plate 20 and the second air guide plate 30. On the first hand, it can prevent wind from blowing directly on the user, thereby improving the user's comfort; on the second hand, the air outlet positions and air outlet areas of the first zero-wind mode and the second zero-wind mode are different, and the heating or cooling efficiencies are different, which can adapt to different needs of users and enhance the practicality of the air conditioner; on the third hand, the pivotal position of the first air guide plate 20 is set at the upper edge of the air outlet 101, so that the length design and rotation of the first air guide plate 20 are not restricted by the size of the air duct, thereby preventing the wind from blowing 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 in the first zero-wind mode, thereby preventing wind from blowing directly on the user, thereby improving the comfort of use of the air conditioner; in addition, 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, thereby improving the wind dispersion or soft wind effect.

[0045] See attached Figure 2In the embodiment of the present invention, if the indoor unit of the air conditioner is in the first zero wind mode, 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° and 55°; the blocking surface A is the plane where the first air guide plate 20 is located when the air outlet 101 is closed. In this way, the wind blown out through the air diffusion 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.

[0046] 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, and is also the same 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.

[0047] See attached Figure 4 In the embodiment of the present invention, if the indoor unit of the air conditioner is in the second zero wind mode, 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 25°-35° and β2 is between 55°-65°. This arrangement can ensure that the bottom end of the first air guide plate 20 is close to or close to the inner surface of the second air guide plate 30, avoiding the gap between the bottom end of the first air guide plate 20 and the second air guide plate 30 to be too large, causing the wind to blow out from the gap, weakening the wind dispersion or soft wind effect.

[0048] See attached Figure 5 and Figure 6 In the embodiment of the present invention, the indoor unit of the air conditioner has a third zero wind mode; the third zero wind mode is configured as follows: the lower end of the first air guide plate 20 and the front end of the second air guide plate 30 are both located at the front end of the air outlet 101, and the lower end of the first air guide plate 20 is close to or in close contact with the front end of the second air guide plate 30; the first air guide plate 20, the second air guide plate 30 and the housing 10 enclose a second side air outlet 103, and the wind is blown out from the air dispersion hole 201 and the second side air outlet 103; wherein the air outlet area of ​​the second side air outlet 103 is greater than the air outlet area of ​​the first side air outlet 102. With such a configuration, the heating or cooling efficiency of the third zero wind mode is higher than that of the second zero wind mode and the first zero wind mode, further meeting the user's requirements for greater heating or cooling efficiency in the zero wind mode, and enhancing the practicality of the air conditioner.

[0049] See attached Figure 6In the embodiment of the present invention, if the indoor unit of the air conditioner is in the third zero wind mode, 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 45°-55° and β3 is between 55°-65°. Such a setting can ensure that the bottom end of the first air guide plate 20 is close to or close to the inner surface of the second air guide plate 30, avoiding the gap between the bottom end of the first air guide plate 20 and the second air guide plate 30 being too large, causing the wind to blow out from the gap, weakening the wind dispersion or soft wind effect.

[0050] See attached Figure 7 and Figure 8 In the embodiment of the present invention, the air conditioner indoor unit also has a normal air outlet mode; the normal air outlet mode is configured as follows: the first air guide plate 20 and the second air guide plate 30 both open the air outlet 101, and 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. Such a configuration can meet the user's needs for rapid heating or cooling.

[0051] See attached Figure 8 In the embodiment of the present invention, if the indoor unit of the air conditioner is in the normal air outlet mode, 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 ɑ6 and β6 respectively satisfy: ɑ4 is between 45°-160° and β4 is between 20°-135°. With such a setting, 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; the first air guide plate 20 and the second air guide plate 30 both have a large rotation range, and the two cooperate to achieve a variety of air supply modes.

[0052] In the embodiment of the present invention, preferably, 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.

[0053] See attached Fig. 9 and Fig.10 In the embodiment of the present invention, the indoor unit of the air conditioner also has a closed mode; the closed mode is configured as follows: the first air guide plate 20 and the second air guide plate 30 both close the outlet, and the second air guide plate 30 blocks the air dispersion hole 201. In this way, when the first air guide plate 20 and the second air guide plate 30 are in the closed state, the second air guide plate 30 can completely cover the air dispersion hole 201 of the first air guide plate 20, thereby preventing dust from entering the air duct through the air dispersion hole 201.

[0056] 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.

[0057] The air-conditioning indoor unit provided in the embodiment of the present invention sets the pivotal position of the second air guide plate 30 at the lower edge of the air outlet 101, so that the length design and rotation of the second air guide plate 30 are not restricted by the size of the air duct, thereby preventing the wind from being blown out from the left and right ends of the air outlet 101 without being blocked by the second air guide plate 30 in the first zero wind mode and the second zero wind mode, thereby preventing the wind from blowing directly on the user, thereby improving the comfort of using the air conditioner.

[0058] In another implementation of the embodiment of the present invention, the second air guide plate 30 is slidably connected to the outside of the housing 10 and can extend to the front side of the air outlet 101 .

[0059] It should be noted that the second air guide plate 30 is slidably connected to the outside of the shell 10, rather than being slidably connected inside the air duct, so that the sliding of the second air guide plate 30 is 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 in the upward direction, avoiding the wind from blowing directly on the user, thereby improving the comfort of using the air conditioner.
