Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

An air conditioning indoor unit 100 according to an embodiment of the present invention, which can cool and heat indoor air, is described below with reference to the accompanying drawings.

As shown in fig. 4 and 6, an air conditioning indoor unit 100 according to an embodiment of the present invention includes: the air conditioner comprises a casing 1, a rotary air duct piece 2, a fan assembly 3 and a switch door 4.

Wherein, can be equipped with air intake 1a on the casing 1, can be equipped with air outlet 2a on the rotatory wind channel spare 2, be equipped with the wind channel space in the rotatory wind channel spare 2, air outlet 2a and air intake 1a all can be linked together with the wind channel space, and rotatory wind channel spare 2 rotationally establishes in order to adjust the air-out direction of air outlet 2a on casing 1. Specifically, when the indoor unit 100 of the air conditioner works, indoor air can enter the casing 1 through the air inlet 1a, the heat exchange component 6 can be arranged in the casing 1, the heat exchange component 6 can exchange heat with air flow, and the air flow after heat exchange can enter the air duct space and can be discharged through the air outlet 2a, so that the purpose of adjusting indoor temperature can be achieved.

Because the rotary air duct piece 2 can rotate relative to the casing 1, the air outlet direction of the air outlet 2a can be conveniently adjusted, and thus the use flexibility of a user is improved. Moreover, the air outlet 2a can synchronously rotate relative to the casing 1 along with the rotary air duct piece 2, so that the air outlet area of the air outlet 2a is kept unchanged, the air outlet angle of the air outlet 2a can be adjusted on the premise of not influencing the air outlet quantity of the air outlet 2a, and the refrigerating and heating efficiency of the air conditioner indoor unit 100 is greatly improved.

For example, the indoor unit 100 may be an on-hook, and the indoor unit 100 may be fixed to a wall. When the indoor unit 100 of the air conditioner performs a cooling operation, because the air density of the cool air is high and the circulation speed is high, in order to prevent the cool air from being directly blown to indoor users, the rotary air duct member 2 can be controlled to rotate so that the air outlet 2a is capable of outputting air in a direction away from indoor people (for example, the rotary air duct member 2 can drive the air outlet 2a to rotate to a position where the air outlet 2a is capable of outputting air directly above the indoor unit 100 of the air conditioner), the cool air can slowly circulate in the indoor space under the action of gravity, so that not only the indoor temperature distribution is more uniform, but also the occurrence of air conditioning diseases caused by the direct blowing of the cool air to the users can be prevented. When the indoor unit 100 of the air conditioner performs heating operation, because the air density of hot air is smaller and the circulation speed is slower, in order to improve the indoor heating speed, the air outlet 2a can be enabled to face the direction opposite to the indoor crowd by controlling the rotation of the rotary air duct member 2 (for example, the rotary air duct member 2 can drive the air outlet 2a to rotate to the position of the air outlet 2a facing the air outlet under the indoor unit 100 of the air conditioner), so that hot air can smoothly circulate to the lower half part of the indoor space, not only can improve the indoor heating efficiency, but also can achieve the effect of foot warming, and the use comfort of a user is greatly improved.

As shown in fig. 6 and 8, the fan assembly 3 may include a first driving motor 31 and a wind wheel 32, the first driving motor 31 may be provided on the cabinet 1, the wind wheel 32 may be provided in the duct space, and the first driving motor 31 may be connected to the wind wheel 32 to drive the wind wheel 32 to rotate. Wherein, the motor shaft of the first driving motor 31 may be spline-connected with the wind wheel 32. When the fan assembly 3 is in operation, the first driving motor 31 can drive the wind wheel 32 to rotate so as to form negative pressure in the air channel space. Under the action of negative pressure, indoor air can enter the air channel space through the air inlet 1a, and air flow in the air channel space can also be discharged through the air outlet 2 a. Alternatively, the rotor 32 may be an axial rotor or a centrifugal rotor.

As shown in fig. 3 to 4, a switch door 4 is movably provided on the rotary duct member 2, and the switch door 4 may be engaged with the rotary duct member 2 to open or close the air outlet 2a. Specifically, the opening and closing door 4 may function to open or close the air outlet 2a. The switch door 4 can completely close the air outlet 2a, and the switch door 4 can also close a part of the air outlet 2a, so that the switch door 4 can also play a role in controlling the air outlet quantity of the air outlet 2a.

For example, when the indoor unit 100 is in operation, the opening and closing door 4 can completely open the air outlet 2a, thereby increasing the air output of the indoor unit 100 and improving the cooling and heating efficiency of the indoor unit 100. When the air outlet volume of the air outlet 2a needs to be reduced, the switch door 4 can be controlled to move relative to the casing 1 so that the switch door 4 closes part of the air outlet 2a, thereby reducing the air outlet area of the air outlet 2a and further reducing the air outlet volume of the air outlet 2 a. When the air conditioner indoor unit 100 stops working, the switch door 4 can be matched with the rotary air duct member 2 to completely seal the air outlet 2a, so that the switch door 4 can play a role in sealing the rotary air duct member 2, dust and dirt in air can be prevented from entering the rotary air duct member 2, the switch door 4 can play a role in protecting the air conditioner indoor unit 100, and the service life of the air conditioner indoor unit 100 can be prolonged.

Alternatively, a plurality of ventilation micro holes (not shown) may be provided on the opening and closing door 4, the plurality of ventilation micro holes penetrating through the opening and closing door 4 in the thickness direction of the opening and closing door 4. When the air outlet 2a is completely closed by the switch door 4, air flow in the air duct space can be discharged through a plurality of ventilation micropores, and the ventilation micropores can reduce the circulation speed of the air flow, so that the air outlet effect without wind sense or soft wind sense can be realized, and the use comfort of a user can be improved.

According to the air conditioning indoor unit 100 of the embodiment of the invention, by arranging the rotary air duct member 2, the rotary air duct member 2 can rotate relative to the casing 1 to adjust the air outlet direction of the air outlet 2a, so that the air supply angle of the air conditioning indoor unit 100 can be increased without influencing the air outlet, and the air supply effect of the air conditioning indoor unit 100 is greatly improved. By arranging the switch door 4 at the air outlet 2a, the switch door 4 can move relative to the casing 1 to open or close the air outlet 2a, thereby not only controlling the air outlet quantity of the air outlet 2a, but also sealing the air outlet 2a, and further playing a good role in protecting the air conditioner indoor unit 100.

According to some embodiments of the present invention, the opening and closing door 4 is rotatably provided on the rotary air duct member 2 to open or close the air outlet 2a, whereby the operation of opening and closing the door 4 can be facilitated. For example, a pivot shaft may be disposed on the rotary air duct member 2, one end of the switch door 4 may be pivotally connected to the pivot shaft, and the other end of the switch door 4 may rotate relative to the rotary air duct member 2 to adjust the air outlet angle and the air outlet area of the air outlet 2 a.

Optionally, the number of the switch door 4 may be one, the number of the switch door 4 may be plural, the plurality of switch doors 4 may rotate relative to the rotary air duct member 2, and the plurality of switch doors 4 cooperate with each other to open or close the air outlet 2a, thereby improving the flexibility of use of the user. For example, two switch doors 4 may be provided at the air outlet 2a, and the two switch doors 4 are rotatable with respect to the air duct member 2. When the air output of the air outlet 2a needs to be increased, the two switch doors 4 can be opened at the same time. When it is necessary to reduce the air output of the air outlet 2a, only one of the switch doors 4 may be opened. When the air conditioner indoor unit 100 stops operating, the two opening and closing doors 4 may be engaged with each other to completely close the air outlet 2a. Thus, by the above arrangement, not only the air outlet 2a can be opened or closed by the two switch doors 4, but also the air outlet volume of the air outlet 2a can be adjusted by the two switch doors 4.

As shown in fig. 4, according to some embodiments of the present invention, the opening and closing door 4 is slidable with respect to the rotary air duct member 2 to open or close the air outlet 2a, so that the matching structure of the opening and closing door 4 and the rotary air duct member 2 can be made more compact. Wherein, a wind outlet 2a can be arranged on the rotary air duct member 2, and a plurality of wind outlets 2a can also be arranged on the rotary air duct member 2. When the rotary air duct member 2 is provided with a plurality of air outlets 2a, a switch door 4 may be disposed at each air outlet 2a, or only one switch door 4 may be disposed, and the switch door 4 may simultaneously open or close the plurality of air outlets 2a.

Alternatively, a storage groove (not shown) may be provided in the rotary air duct member 2, and the switch door 4 may be stored in the storage groove to open the air outlet 2a, thereby making the mating structure of the switch door 4 and the rotary air duct member 2 more compact. Specifically, when the air outlet 2a needs to be closed, the switch door 4 can slide forward and extend out of the storage slot, and the switch door 4 can be matched with the rotary air duct member 2 to close the air outlet 2a. When the air outlet 2a needs to be opened, the switch door 4 can reversely slide, and the switch door 4 can be stored in the storage groove. When the opening and closing door 4 is completely accommodated in the accommodating groove, the air outlet 2a is completely opened.

As shown in fig. 1-2, according to some embodiments of the present invention, a plurality of first air guiding louvers 5 distributed at intervals may be disposed at the air outlet 2a, and the plurality of first air guiding louvers 5 may rotate relative to the rotary air duct member 2 to adjust the air outlet angle of the air outlet 2a, so that the air supply wide angle of the air outlet 2a may be increased, and thus the air supply range of the indoor unit 100 of the air conditioner may be increased.

Optionally, at least one first air guiding louver 5 may be provided with a plurality of first air outlet micropores 51 distributed at intervals, where the plurality of first air outlet micropores 51 penetrate through the first air guiding louver 5 in the thickness direction of the first air guiding louver 5. That is, the first air outlet micro holes 51 may be formed in one of the first air guiding louvers 5, the first air outlet micro holes 51 may be formed in a plurality of the first air guiding louvers 5, and the first air outlet micro holes 51 may be formed in each of the first air guiding louvers 5. When the first air guiding louvers 5 rotate to a position where the air outlet 2a is completely blocked, the air flow in the air duct space can be discharged through the first air outlet micropores 51, and the first air outlet micropores 51 can divide the air flow into a plurality of fine branched air flows. Moreover, because the aperture of the first air outlet micropore 51 is smaller, when the air flow flows out from the first air outlet micropore 51, the first air outlet micropore 51 can play a role in reducing the speed of the air flow, thereby playing a role in air outlet without wind sensation or soft wind sensation and improving the use comfort of users.

In some embodiments of the present invention, a plurality of second air guiding louvers (not shown) are disposed at inner sides of the plurality of first air guiding louvers 5 and are spaced apart, the plurality of second air guiding louvers can rotate relative to the rotating air duct member 2, and the plurality of second air guiding louvers can cooperate with the plurality of first air guiding louvers 5 to adjust an air outlet angle of the air outlet 2a, so that an air supply angle of the air outlet 2a can be increased, and thus refrigerating and heating efficiencies of the indoor unit 100 of the air conditioner can be improved.

Optionally, the extending length of the first wind guiding louvers 5 may be the same as the extending length of the second wind guiding louvers, and the first wind guiding louvers 5 and the second wind guiding louvers may also extend along different directions. For example, the plurality of first wind guiding louvers 5 may extend along the axial direction of the rotary air duct member 2, and the extending direction of the plurality of second wind guiding louvers may be perpendicular to the extending direction of the plurality of first wind guiding louvers 5.

In some embodiments of the present invention, at least one second air guiding louver may be provided with a plurality of second air outlet micropores that are distributed at intervals, and the plurality of second air outlet micropores penetrate through the second air guiding louver in a thickness direction of the second air guiding louver. That is, the second air outlet micropores may be formed in one of the second air guiding louvers, the second air outlet micropores may be formed in a plurality of the second air guiding louvers, and the second air outlet micropores may be formed in each of the second air guiding louvers. When the first air guiding louvers 5 and the second air guiding louvers rotate to the position of completely shielding the air outlet 2a, the air flow in the air duct space can be discharged through the second air outlet micropores, and the second air outlet micropores can divide the air flow into a plurality of tiny branch air flows. Moreover, because the aperture of each second air outlet micropore is smaller, when the air flow flows out from the second air outlet micropore, the second air outlet micropore can play a role in reducing the speed of the air flow. When the air flow flowing through the second air guiding louver is discharged through the first air outlet micropore 51 again, the first air outlet micropore 51 can achieve the purpose of secondary speed reduction on the air flow, and therefore the air outlet effect without wind sensation can be achieved, and the use comfort level of a user is greatly improved.

It should be noted that, the rotation angles of the first wind guiding louvers 5 and the second wind guiding louvers with respect to the casing 1 may be selected according to actual use requirements, which is not particularly limited in the present invention.

In some embodiments of the present invention, the decorative ring 23 may be configured to cooperate with the cabinet 1 to define a rotation angle of the rotary air duct member 2, whereby the normal operation of the air conditioning indoor unit 100 can be ensured. For example, the decorative ring 23 may extend outwardly relative to the outer peripheral wall of the rotary air channel member 2. When the air outlet 2a is driven by the rotating air duct member 2 to rotate in a direction approaching to the casing 1, the decorative ring 23 can be stopped on the casing 1 to prevent the air outlet 2a from rotating to the inner side of the casing 1, so that the air conditioner indoor unit 100 can be ensured to normally outlet air.

In some embodiments of the present invention, the decorative ring 23 may be formed into a closed ring shape, and the decorative ring 23 may be provided with an air outlet grille 232 disposed opposite to the air outlet 2a, where the air outlet grille 232 may protect the air outlet 2a, and may prevent dust in air from falling into the casing 1 through the air outlet 2 a.

In the specific example shown in fig. 7, the bezel 23 may include a body portion 231 and an outlet grill 232, wherein the body portion 231 is formed in a closed ring shape and disposed around the air outlet 2a, and the body portion 231 extends outwardly with respect to the outer circumferential wall of the rotary air duct member 2. The air outlet grille 232 is arranged in the body 231, the air outlet grille 232 is opposite to the air outlet 2a, an air outlet space is arranged on the air outlet grille 232, and air flow can be discharged through the air outlet space. When the bezel 23 is assembled with the rotary air channel member 2, the body portion 231 may be snap-fitted with the outer peripheral wall of the rotary air channel member 2.

According to some embodiments of the present invention, the number of the rotary air duct members 2 may be plural, each rotary air duct member 2 is rotatably provided on the casing 1, and each rotary air duct member 2 is provided with an air outlet 2a.

Alternatively, the plurality of rotary air channel members 2 may be independently rotated, that is, the rotation angle of each rotary air channel member 2 may be separately controlled, whereby the use flexibility of the user may be improved.

As shown in fig. 7 to 8, in some embodiments of the present invention, the number of the rotating duct members 2 may be two, the two rotating duct members 2 may be spaced apart in the length direction (left-right direction as shown in fig. 7) of the casing 1, the first driving motor 31 may be a dual-shaft motor, and the first driving motor 31 is respectively connected to the wind wheels 32 in the two rotating duct members 2. Specifically, the first driving motor 31 may include a first motor shaft 311 and a second motor shaft 312, the first motor shaft 311 may be connected to the wind wheel 32 in one of the rotary air duct members 2, and the second motor shaft 312 may be connected to the wind wheel 32 in the other rotary air duct member 2. When the fan assembly 3 works, the first driving motor 31 can drive the two wind wheels 32 to synchronously rotate, so that the fan assembly 3 can run more stably. Moreover, the first driving motor 31 is formed as a double-shaft motor, so that the matching structure of the first driving motor 31 and the casing 1 is more compact, the assembly space can be saved, and the assembly efficiency of the fan assembly 3 can be improved.

The design of the fan assembly 3 is not limited to this. For example, the fan assembly 3 may further include two first driving motors 31, the two first driving motors 31 may be disposed back-to-back, and a motor shaft of each first driving motor 31 may be connected to the wind wheel 32 in one of the rotating duct members 2. Wherein the operating states of the two first driving motors 31 can be controlled respectively. The two first driving motors 31 can rotate at the same speed (the rotation speeds of the two first driving motors 31 are the same), the two first driving motors 31 can also rotate at different speeds (the rotation speeds of the two first driving motors 31 are different), only one of the first driving motors 31 can be controlled to rotate, and the two first driving motors can be selectively arranged according to actual use requirements.
