Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] At present, most air guide plates in air conditioners use a single air guide plate for air guidance. The air guide plate can only swing along the air outlet, and the movement range of the air guide plate is limited. The air supply mode of the air conditioner is single and cannot meet the requirements of effective rectification of the airflow under different working conditions. It may even hinder the airflow blown out from certain angles, affecting the air output and temperature control effect of the air conditioner.

[0028] To this end, the present invention proposes an air-conditioning indoor unit, aiming to provide an air-conditioning indoor unit with a larger air outlet range, better air supply comfort, and multiple air supply modes to meet the use requirements of different working conditions.

[0029] Reference Figures 1 to 8 In one embodiment of the present invention, the air conditioner indoor unit 1000 includes a shell 100 and an air guide assembly 200. An air duct 110 is formed in the shell 100, and the air duct 110 has an air outlet 111. The air guide assembly 200 is arranged at the air outlet 111, and the air guide assembly 200 includes at least three air guide plates, and any air guide plate can rotate at the air outlet 111, so that at least three air guide plates have a closed state in which the air outlet 111 is jointly closed, and an air outlet state in which the air outlet 111 is at least partially opened.

[0030] The air conditioner indoor unit 1000 can be vertical or wall-mounted. The air conditioner indoor unit 1000 usually has an air guide plate structure, which is installed at the air outlet 111 of the air conditioner. By rotating at different angles, gas diversion is achieved to meet the comfort requirements of air supply in different directions and angles. However, most single air guide plates can only swing along the air outlet 111, and the movement range of the air guide plates is limited. At present, there are also some air guide plates that use other solutions, such as: double-layer air guide plates, fully closed large air guides, and rotating air guide plates.

[0031] Conventional double-layer air guide plates usually cannot fully close the air outlet. When the air guide plates are closed, there will be a gap under the fuselage, which is not conducive to dust prevention and the overall appearance of the machine. In addition, the double-layer air guide plates are difficult to effectively press down the hot air in the heating mode, and the heating comfort is poor.

[0032] The fully closed large air guide of the air outlet is usually driven by left and right dual motors, and a small air guide plate driven by a single motor is set inside. The small air guide plate has poor air guiding effect. It is difficult to effectively press the hot air downward in the heating mode, and the heating comfort is not good.

[0033] The rotating air guide plate has an intermediate support structure, and there is a dead zone in the air sweeping process of the air guide plate. It needs to be flipped to switch the angle of upward and downward air blowing, and lacks a large air sweeping range. In addition, the air outlet cannot be fully closed, and there is a large closing gap.

[0034] Specifically, the housing 100 includes a chassis (not marked in the figure) and a face frame (not marked in the figure), and the chassis and the face frame cooperate to form an air duct 110, and the air duct 110 has an air outlet 111, and the hot air or cold air blown out by the air conditioner indoor unit 1000 can be blown into the room through the air outlet 111. The air guide assembly 200 is arranged at the air outlet 111, and the air outlet 111 can be rotatably closed or the opening of the air outlet 111 can be changed through at least three air guide plates, so as to guide the airflow blown out from the air outlet 111. In this way, through the arrangement of multiple air guide plates, different air outlet effects can be achieved in the cooling mode or heating mode of the air conditioner, and the airflow under different working conditions can be effectively rectified, thereby improving the air volume and temperature adjustment effect of the air conditioner.

[0035] The at least three air guide plates may be three air guide plates arranged in sequence, four air guide plates, five air guide plates, etc. The air guide plates may be spliced ​​in sequence or arranged in layers. For example, among the four air guide plates, in the closed state, one of the air guide plates may be stacked with another air guide plate; and they may be spliced ​​together in the air outlet state.

[0036] The technical solution of the present invention is through at least three independently driven air guide plates arranged at the air outlet 111 of the shell 100. Any air guide plate can rotate at the air outlet 111, so that at least three air guide plates have a closed state in which the air outlet 111 is jointly closed, and an air outlet state in which the air outlet 111 is at least partially opened. In this way, a variety of air supply modes can be realized through the combination of different rotation angles, rotation directions and rotation speeds. Compared with the existing double-layer air guide plates, large air guides with fully closed air outlets, and rotating air guide plates, the arrangement of at least three air guide plates can not only solve the problem of appearance, but also realize full closure of the air outlet to ensure the aesthetic appearance and dust-proof effect; it can also realize different air outlet effects in the cooling mode or heating mode of the air conditioner, thereby improving the air outlet and temperature control effect of the air conditioner.

[0037] The following is an example in which the number of air guide plates is three.

[0038] Reference Figures 1 to 4 The first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 jointly close the air outlet 111. Compared with using a single air guide plate to close the air outlet 111, the appearance of the air conditioner can be improved and the size of the gap in the appearance can be reduced. A single windshield plate is limited by the manufacturing process and the error in the assembly process, and the appearance gap with the air outlet 111 is large in the closed state and the start-up state. In this way, the first air guide plate 230 and the second air guide plate 240 are set, which can not only solve the appearance problem, but also achieve different air outlet effects in the cooling mode or heating mode of the air conditioner, thereby improving the air volume and temperature control effect of the air conditioner.

[0039] It should be noted that rotation means that the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 cooperate to close the air outlet 111 by rotating around the center of a circle; or, the opening of the air outlet 111 is changed, thereby controlling the airflow blowing out of the air outlet 111.

[0040] The opening of the air outlet 111 refers to the process from the closed state of the air outlet 111 to the air outlet state, that is, the process from the air outlet 111 being completely blocked by the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 to the air outlet 111 being exposed. The more area of ​​the air outlet 111 that is exposed, the larger the opening of the air outlet 111, and vice versa.

[0041] In order to ensure that the air guide assembly 200 covers the air outlet 111 when in the closed state and ensure the appearance of the air-conditioning indoor unit 1000, the rotation center and / or rotation radius of at least three air guide plates are the same, and in the closed state, at least three air guide plates are spliced ​​in sequence to jointly close the air outlet 111.

[0042] The center of the outer arc of the existing air guide plate does not coincide with its rotation center, which results in a larger appearance gap in the closed state and the started state, and air leakage is prone to occur during the process of air blowing out from the air outlet 111, and turbulence is generated at the air guide plate, affecting the air outlet effect. It can be imagined that the air outlet 111 is usually a rectangular cross-section, and the movement trajectory of the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 is a circle. In this way, the circle is placed in the rectangle, and the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 can be closer to the cavity wall of the air outlet 111, so that they are regarded as part of the air outlet 111, reducing the problem of air leakage and improving the problem of large appearance gap affecting the appearance.

[0043] In order to ensure the air outlet effect and optimize the structure, the width of at least three air guide plates along the rotation direction is the same. In this way, in cooling mode, cold air can be blown upward to prevent direct blowing, and warm air can be blown downward to the wall in heating mode.

[0044] Without loss of generality, in one embodiment, the width dimensions of the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 along the rotation direction are all the same, so that the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 can be used interchangeably, reducing production costs.

[0045] In another embodiment, the width dimensions of the first air guide plate 230 and the third air guide plate 250 along the rotation direction are the same and both are larger than the width dimension of the second air guide plate 240 along the rotation direction; thus, different air outlet effects can be achieved in subsequent change modes.

[0046] In another embodiment, the width dimension of the third air guide plate 250 along the rotation direction is greater than the width dimension of the first air guide plate 230 along the rotation direction, and the width dimension of the second air guide plate 240 along the rotation direction is greater than or equal to the width dimension of the first air guide plate 230 along the rotation direction, and the sum of the widths of the first air guide plate 230 and the second air guide plate 240 is greater than the third air guide plate 250. In this way, in cooling mode, the cold air can be prevented from being blown directly upward, and the warm air can be delivered downward along the wall in heating mode.

[0047] It can be understood that by using multiple air guide plates, it is not necessary to flip any air guide plate at a large angle when in the air outlet state, so the air conditioner indoor unit 1000 also includes an air guide plate bracket (not shown in the figure), the air guide plate bracket is connected to the housing 100, and at least three air guide plates include a first air guide plate 230, a second air guide plate 240 and a third air guide plate 250, and the three air guide plates are all connected to the air guide plate bracket. The structural strength of the air guide assembly 200 is enhanced by arranging the air guide plates, and the air guide plates and the air guide plate bracket will not interfere with each other.

[0048] In order to improve the air outlet effect, the air conditioner indoor unit 1000 also includes a louver wind sweeping structure (not shown in the figure), and the multiple wind sweeping blades of the louver wind sweeping structure are arranged at intervals along the rotation axis of the first air guide plate 230 and can swing along the rotation axis of the first air guide plate 230.

[0049] In addition, in order to optimize the space, the shutter wind sweeping structure is integrated with the wind guide plate bracket, and the multiple wind sweeping blades of the shutter wind sweeping structure are arranged at intervals along the rotation axis of the first wind guide plate 230 and can swing along the rotation axis of the first wind guide plate 230, and the shutter wind sweeping structure is engaged with the first wind guide plate 230. The wind sweeping blades include blades in the vertical wind direction and blades in the horizontal wind direction, which are connected in series by a pull rod, and when working, they are driven by a motor to swing in the vertical direction or in the horizontal direction.

[0050] Furthermore, in order to better improve the air volume and temperature adjustment effect of the air conditioner, the inner surface of at least one air guide plate at the air outlet 111 is a concave arc surface.

[0051] In one embodiment, in order to better improve the air output and temperature control effect of the air conditioner, the side of the first air guide plate 230 facing the louver wind sweeping structure is a concave arc surface. The concave arc surface of the first air guide plate 230140 can guide the airflow, thereby cooperating with the positions of the first air guide plate 230 and the second air guide plate 240, so that different air output effects can be achieved in the cooling mode or heating mode of the air conditioner, thereby improving the air output and temperature control effect of the air conditioner.

[0052] In another embodiment, the inner surface of the second air guide plate 240 is a concave arc surface.

[0053] In yet another embodiment, the inner surface of the third air guide plate 250 is a concave arc surface.

[0054] The concave arc surfaces of the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250 can guide the airflow, so that in coordination with the positions of the first air guide plate 230, the second air guide plate 240 and the third air guide plate 250, different air outlet effects can be achieved in the cooling mode or heating mode of the air conditioner, thereby improving the air outlet and temperature control effects of the air conditioner.

[0055] Reference Figures 5 to 8 In the cooling mode, the length of the first air guide plate 230 and the second air guide plate 240 is greater than that of the third air guide plate 250, and the concave arc surfaces of the first air guide plate 230 and the second air guide plate 240 guide the airflow. The direction of the airflow passing through the first air guide plate 230 and the second air guide plate 240 is the same as the concave arc surface. If the third air guide plate 250 is set to a concave arc surface, it will also have an adsorption effect on the airflow, so that the airflow will be deflected downward, so that the airflow can be transported farther, thereby increasing the air guide range and improving the comfort of air supply.

[0056] According to the positions and combinations of the first air guide plate 230 , the second air guide plate 240 and the third air guide plate 250 in the cooling mode or the heating mode, the air conditioner indoor unit 1000 has different air outlet modes.

[0057] In the air outlet state, at least three air guide plates are divided into an upper air guide portion 210 and a lower air guide portion 220; the upper air guide portion 210 is located at the avoidance upper portion 121 or the lower air guide portion 220 is located at the avoidance lower portion 131, so that the air outlet 111 can be at least partially opened.

[0058] Specifically, the shell 100 includes an upper duct wall 120 and a lower duct wall 130 which together constitute the duct 110. The upper duct wall 120 and the lower duct wall 130 are respectively suitable for bending to form an avoidance upper part 121 and a avoidance lower part 131 at parts close to the air outlet 111. The first air guide plate 230 can be rotated to avoid the lower part 131, the third air guide plate 250 can be rotated to avoid the upper part 121, and the second air guide plate 240 moves between the first air guide plate 230 and the third air guide plate 250, so that the air-conditioning indoor unit 1000 has different air outlet modes.

[0059] Reference Figure 5The air conditioner indoor unit 1000 has a cooling mode. In the cooling mode, the number of air guide plates of the lower air guide portion 220 is greater than the number of air guide plates of the upper air guide portion 210, and the width of the lower air guide portion 220 is greater than the width of the upper air guide portion 210. In the cooling mode, the first air guide plate 230 is located at the avoidance lower portion 131, the third air guide plate 250 is located at the avoidance upper portion 121, and the second air guide plate 240 overlaps the first air guide plate 230. Since the length of the first air guide plate 230 and the second air guide plate 240 is greater than the length of the third air guide plate 250, the avoidance upper portion 121 and the avoidance lower portion 131 are arc-shaped, and the length of the arc-shaped avoidance lower portion 131 is slightly greater than or equal to the length of the first air guide plate 230 and the second air guide plate 240. The first air guide plate 230 and the second air guide plate 240 are spliced, and the outer surfaces of the two are suitable for the arc-shaped avoidance lower portion 131, and the outer surface of the third air guide plate 250 is suitable for being placed at the arc-shaped avoidance upper portion 121. In this way, there will be no problem of air leakage. The first air guide plate 230 and the second air guide plate 240 are equivalent to the arc-shaped avoidance lower part 131, which cooperate to form an air outlet section, and the inner surfaces of the first air guide plate 230 and the second air guide plate 240 are concave arc surfaces, so that the airflow produces an adsorption effect through the second air guide plate 240. In this way, in the cooling mode, the cooperation of the first air guide plate 230 and the second air guide plate 240 makes the cold air outlet smooth, the air volume attenuation is small, the air supply range is wider, and the user experience is better.

[0060] Reference Figure 6 The air conditioner indoor unit 1000 has a heating mode. In the heating mode, the number of air guide plates of the upper air guide portion 210 is greater than the number of air guide plates of the lower air guide portion 220, and the width of the upper air guide portion 210 is greater than the width of the lower air guide portion 220.

[0061] Specifically, in the heating mode, the first air guide plate 230 is located at the avoidance lower portion 131 , the third air guide plate 250 is located at the avoidance upper portion 121 , and the second air guide plate 240 is spliced ​​with the third air guide plate 250 . In the heating mode, hot air passes through the second air guide plate 240 and the third air guide plate 250 from the air duct 110. Since the lengths of the second air guide plate 240 and the third air guide plate 250 are greater than those of the first air guide plate 230, a downward gap is formed between the second air guide plate 240 and the third air guide plate 250 and the first air guide plate 230. The outer surface of the first air guide plate 230 is suitable for being placed at the arc-shaped avoidance lower part 131, and no air leakage problem will occur. The inner surface of the first air guide plate 230 is a concave arc surface, so that the airflow generates a guiding adsorption effect through the first air guide plate 230, and is guided to the gap through the first air guide plate 230 to stay. The hot air can sink better along the wall, so that the heating air volume can be increased and the hot air supply effect is better.

[0062] Reference Figure 7The air conditioner indoor unit 1000 has a dual wind mode. In the dual wind mode, at least three air guide plates are further divided into a middle air guide portion, the middle air guide portion includes at least one air guide plate, the lower air guide portion 220 is located at the avoidance lower portion 131, the upper air guide portion 210 is located at the avoidance upper portion 121, the middle air guide portion is located between the upper air guide portion 210 and the lower air guide portion 220, the middle air guide portion and the upper air guide portion 210 form a first opening 112 spaced apart in the width direction of the air outlet 111, and the middle air guide portion and the lower air guide portion 220 form a second opening 113 spaced apart in the width direction of the air outlet 111.

[0063] Specifically, in the dual wind mode, the first air guide plate 230 is located at the avoidance lower part 131, the third air guide plate 250 is located at the avoidance upper part 121, and the second air guide plate 240 is located between the first air guide plate 230 and the third air guide plate 250. The first air guide plate 230 and the second air guide plate 240 form a first opening 112 in the width direction of the air outlet 111, and the second air guide plate 240 and the third air guide plate 250 form a second opening 113 in the width direction. In the dual wind mode, the air conditioner indoor unit 1000 can be cooling or heating, the first opening 112 and the second opening 113 can be the same, or the first opening 112 is larger than the second opening 113, or the first opening 112 is smaller than the second opening 113, so that the area in the room can be zoned for air supply to meet the blowing needs of users in different areas of the room.

[0064] Furthermore, the air conditioning indoor unit 1000 also has a change mode. In the change mode, the middle air guide portion moves between the upper air guide portion 210 and the lower air guide portion 220, so that the first opening 112 and the second opening 113 change accordingly.

[0065] Reference Figure 8 Specifically, in the change mode, the second air guide plate 240 moves between the first air guide plate 230 and the second air guide plate 240, so that the first opening 112 and the second opening 113 change accordingly. On the basis of the two-way mode, the second air guide plate 240, the first air guide plate 230 and the third air guide plate 250 divide the air outlet 111 into two air supply areas. The second air guide plate 240 in the middle performs reciprocating motion to change the air volume and the air supply angle of the two air supply areas, thereby realizing variable speed air supply, simulating natural wind, and bringing a more comfortable blowing experience.

[0068] In one embodiment, the first motor 300 and the second motor 400 are respectively located on both sides of the first air guide plate 230, and the third motor 500 is located between the two first mounting lugs 231 of the first air guide plate 230, or is located in the air guide plate bracket. The first motor 300 drives the first rotating shaft 310, the second motor 400 drives the second rotating shaft 410, and the third motor 500 drives the third rotating shaft 510.

[0069] In another embodiment, the first rotating shaft 310 passes through the second rotating shaft 410 and is inserted into the first shaft hole 232, the second rotating shaft 410 passes through the third avoidance hole 253 and is inserted into the second shaft hole 243, and the third rotating shaft 510 passes through the first avoidance hole 233 and the second avoidance hole 242 and is inserted into the third shaft hole 252; the first motor 300 is arranged beside the second motor 400, and the driving shaft of the second motor 400 is coaxially arranged with the first rotating shaft 310 and the second rotating shaft 410. The first motor 300 drives the second rotating shaft 410 through the transmission mechanism 600, and the first rotating shaft 310 can rotate relative to the second rotating shaft 410.

[0070] Regarding the transmission mechanism 600, in one embodiment, the transmission mechanism 600 is configured as a gear assembly, which includes a driving gear 610 connected to the driving shaft of the second motor 400 and a driven gear disposed on the second rotating shaft 410, and the driving gear 610 is meshed with the driven gear.

[0071] In another embodiment, the transmission mechanism 600 is configured as a synchronous belt pulley mechanism or a gear chain mechanism, etc.

[0072] During startup, the first motor 300 drives the first rotating shaft 310, and the first rotating shaft 310 engages with the first shaft hole 232, thereby driving the first air guide plate 230 to rotate; the first rotating shaft 310 and the second rotating shaft 410 are concentrically arranged and can rotate relative to each other; when the second motor 400 drives the second rotating shaft 410 to rotate through the transmission mechanism 600, the first rotating shaft 310 does not move, and the second rotating shaft 410 drives the second shaft hole 243 to drive the second air guide plate 240 to rotate; the third motor 500 is arranged relative to the first motor 300 and the second motor 400, and is arranged next to the first motor 300 and the second motor 400. The first motor 300, the second motor 400 and the third motor 500 can be installed on the chassis, or arranged on the air guide plate bracket, so as to realize independent driving of the three air guide plates and realize concentric rotation under the drive of different drive motors.

[0073] The first motor 300 drives the first air guide plate 230, the second motor 400 drives the second air guide plate 240, and the third motor drives the third air guide plate 250. The drive of the louver wind sweeping structure can be combined with the first motor 300 and the third motor 500, such as the first motor 300 drives the swing of the vertical wind sweeping blades, and the third motor 500 drives the swing of the horizontal wind sweeping blades; or, the drive of the louver wind sweeping structure can also be driven by a separate drive motor.

[0074] In order to ensure more stable rotation of the three air guide plates and better stability when playing the role of wind guide and reduce noise generation, the first air guide plate 230 is also provided with a first connecting lug 234, and the first connecting lug 234 is provided with a first connecting shaft hole 235. The second air guide plate 240 is also provided with a second connecting lug 244 between the two second mounting lugs 241.

The third air guide plate 250 is provided with a third connecting lug 254, and the third connecting lug 254 is provided with a second connecting shaft hole 255. The first connecting shaft hole 235 and the second connecting shaft hole 255 are both connected to the mounting shaft 245.

[0075] The first connecting lug 234 is arranged in the middle position of the first air guide plate 230, and the second connecting lug 244 extends to both ends and is provided with a mounting shaft 245, so that after the first air guide plate 230 and the third air guide plate 250 are embedded in the mounting shaft 245 during installation, the interference with the first air guide plate 230 and the third air guide plate 250 in the length direction is small, and it can also play a role in pre-fixing the first air guide plate 230 and the third air guide plate 250, which is convenient for the subsequent assembly of the first air guide plate 230 and the third air guide plate 250 and the air guide bracket. The second air guide plate 240 plays a transmission and connection role in the middle, which can ensure that the rotation of the first air guide plate 230 and the third air guide plate 250 is more stable and the stability is better when playing the wind guiding role, thereby reducing the generation of noise and will not reduce the air supply effect.

[0076] To ensure smoother rotation and avoid rotation interference among the first air guide plate 230 , the second air guide plate 240 and the third air guide plate 250 , the gap between the second rotating shaft 410 and the second shaft hole 243 is smaller than the gap between the first shaft hole 232 and the first rotating shaft 310 .

[0077] Specifically, the gap between the second rotating shaft 410 and the second shaft hole 243 is 1 mm.

[0078] The present invention also proposes an air conditioner (not shown in the figure), which includes an air conditioner indoor unit 1000 and an air conditioner outdoor unit (not shown in the figure). The specific structure of the air conditioner indoor unit 1000 refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the air conditioner outdoor unit and the air conditioner outdoor unit are connected by a pipeline to form a refrigerant circuit. Without loss of generality, the air conditioner indoor unit 1000 and the air conditioner outdoor unit can also be an integrated unit.

[0079] Taking a wall-mounted air conditioner as an example, the air conditioner includes the following main components: Wall-mounted indoor unit: The indoor unit is a component installed on the indoor wall, responsible for handling air circulation and temperature regulation. It usually contains components such as fans, filters, evaporators and control panels.

[0080] Compressor unit: The compressor unit is usually installed outdoors and is used to compress and circulate refrigerant. It consists of a compressor, condenser, electronic controller, etc., and is used to convert refrigerant into high-temperature and high-pressure gas and discharge the heat outdoors.

[0081] Connecting pipes: Connecting pipes are used to connect the indoor unit and the outdoor unit to transmit refrigerant, cold water, power lines, etc. Among them, liquid pipes are used to transmit high-pressure condensate, and gas pipes are used to transmit low-pressure evaporative gas.

[0082] Remote control: Wall-mounted air conditioners are usually equipped with a remote control, which allows users to easily set temperature, select modes, adjust fan speed, and switch on and off the timer.

[0083] Duct system: The wall-mounted air conditioner delivers cool air into the room through the duct system and circulates the air through the fan to achieve indoor temperature regulation and air flow.

[0084] These components work together to enable the wall-mounted air conditioner to effectively cool or heat the indoor space and provide a comfortable indoor environment for the user.

[0085] For example, an integrated air conditioner may differ in structure from a wall-mounted air conditioner, but the basic principles are roughly the same.

[0086] In summary, the air outlet has three independently driven air guide plates, which rotate concentrically. Through the combination of different rotation angles, rotation directions and rotation speeds, a variety of air supply modes can be realized, that is, ultra-wide-angle upper and lower air sweeping can be realized; in cooling mode, cold air can be blown upward to prevent direct blowing; in heating mode, warm air can be supplied downward to the wall, and other air supply forms; variable-speed air supply can be realized to simulate natural wind and bring a more comfortable blowing experience; upper and lower zoned air supply can be realized to meet the blowing needs of users in different areas of the room; the air outlet can be fully closed to ensure the appearance and dust-proof effect.

[0087] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
