Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit. Background Technology

[0002] With the development of air conditioning technology, the appearance and functions of air conditioning indoor units are constantly being updated and replaced, and various new technologies are emerging one after another.

[0003] However, there are very few innovative designs for the airflow guidance structure of air conditioner indoor units. Existing solutions typically involve placing an air guide vane and a swivel assembly at the air outlet. The air guide vane adjusts the vertical angle of the air outlet, while the swivel vanes provide horizontal airflow. The widespread use of this airflow guidance structure in existing air conditioner indoor units results in a uniform user experience and product appearance, making it difficult to elevate the product's perceived quality.

[0004] Therefore, how to innovate in air guiding structure has become a technical problem that the air conditioning industry urgently needs to solve. Summary of the Invention

[0005] One objective of this invention is to provide an indoor air conditioning unit with a novel air guide plate to enhance product differentiation and user experience.

[0006] A further objective of this invention is to enrich the air guiding modes of the air guide plate.

[0007] Specifically, the present invention provides an indoor air conditioning unit, comprising:

[0008] The casing has an air outlet.

[0009] At least one slide rail is formed in the housing or mounted on the housing;

[0010] An air guide plate, used to guide the airflow direction of the air outlet, has at least one sliding part, each of the sliding parts being disposed within one of the slide rails; and

[0011] At least one swing arm is rotatable about a fixed axis at its first end, and its second end is rotatably connected to the air guide plate, with the rotation axes both perpendicular to the plane where the slide rail is located;

[0012] The indoor unit of the air conditioner is configured such that by rotating the swing arm about its first end, the sliding part slides along the slide rail, thereby changing the position of the air guide plate.

[0013] Optionally, the indoor unit of the air conditioner also includes a motor for driving the swing arm to rotate about its first end.

[0014] Optionally, the indoor unit of the air conditioner is configured to allow the air guide vane to reciprocate between a first closed state, an open state, and a second closed state; and

[0015] In the first closed state, the air guide plate blocks the air outlet, and the second end of the swing arm is located between the sliding part and the first end of the swing arm;

[0016] In the first closed state, the motor is allowed to rotate forward, causing the air guide plate to flip to the open state, where the air guide plate is parallel to the swing arm; and

[0017] In the open state, the motor is allowed to continue rotating forward to cause the sliding part to rotate within the slide rail, so that the air guide plate continues to open; or the motor is allowed to reverse to cause the sliding part to rotate within the slide rail, so that the air guide plate rotates to the second closed state, blocking the air outlet.

[0018] Optionally, the indoor unit of the air conditioner is a wall-mounted indoor unit, and the casing, the air outlet, and the air guide plate are all elongated strips extending horizontally; and

[0019] Each of the slide rails extends along the width of the air outlet.

[0020] Optionally, the air outlet is located in the lower front region of the housing; and

[0021] The first end of each swing arm is adjacent to the lower end of the air outlet.

[0022] Optionally, the rotation axis of the first end of the swing arm is located within the slide rail.

[0023] Optionally, the second end of the swing arm is rotatably connected to the central portion of the air guide plate in the width direction.

[0024] Optionally, each of the sliding portions is disposed at an end in the width direction of the air guide plate.

[0025] Optionally, the number of slide rails is two, respectively formed on two lateral sidewalls of the housing; and

[0026] There are two sliding parts, located at both ends of the length direction of the air guide plate.

[0027] Optionally, each of the slide rails extends in a straight line at least in the section that mates with the sliding part.

[0028] The indoor air conditioner unit of this invention, by incorporating a slide rail and a swing arm, allows the air guide plate to move in a composite motion, involving sliding along the slide rail and rotating around its sliding portion. This composite motion changes the position of the air guide plate, thereby opening or closing the air outlet and adjusting its air guiding angle. The novel and ingenious movement mechanism of the air guide plate in this invention enhances product differentiation and user experience.

[0029] Furthermore, the indoor unit of the air conditioner of the present invention can not only use the forward rotation of the motor to make the air guide plate reciprocate between the first closed state and the open state, but also use the reverse rotation of the motor to make the air guide plate rotate from the open state to the second closed state, which makes the air guide plate more versatile.

[0030] Furthermore, in the indoor unit of the air conditioner of the present invention, the slide rail extends along the width direction of the air outlet, and the sliding part of the air guide plate is located at its end. In this way, no matter where the air guide plate moves to, one end of it is on the air outlet cross section of the air outlet, so that it can better guide the air direction.

[0043] This invention provides an indoor unit for an air conditioner. The indoor unit is the indoor portion of an air conditioner, used to regulate indoor air, such as cooling / heating, dehumidifying, purifying, and introducing fresh air. This invention does not limit the style of the indoor unit; it can be wall-mounted, floor-standing, ceiling-mounted, etc. Figures 1 to 7 This illustration shows an example of a wall-mounted air conditioner indoor unit.

Figure 5 yes Figure 4 The diagram shows the indoor unit of the air conditioner when the air guide plate 50 reaches the open position. Figure 6 yes Figure 5 The diagram shows the indoor unit of the air conditioner rotating towards the second closed state as the air guide plate 50 rotates. Figure 7 yes Figure 6 The diagram shows the indoor unit of the air conditioner when the air guide plate 50 reaches the second closed state.

[0045] like Figures 1 to 7 As shown, the indoor unit of an air conditioner according to an embodiment of the present invention generally includes a housing 10, at least one slide rail 15, an air guide plate 50, and at least one swing arm 61.

[0046] The housing 10 defines a receiving space within which other components of the indoor air conditioning unit are housed, and regulates airflow, such as cool or hot air. The housing 10 has an air outlet 12 for distributing its regulated airflow to the indoor environment. Please refer to [reference needed]. Figure 1 . Figure 1 This illustration shows an embodiment of a wall-mounted air conditioner indoor unit. In this embodiment, both the housing 10 and the air outlet 12 are elongated strips extending horizontally, with their length direction being... Figure 1 The middle mark is the x-direction.

[0047] The slide rail 15 is formed in or mounted on the housing 10. That is, the slide rail 15 can be part of the housing 10, for example, it can be a groove formed on the inner surface of the housing 10. Alternatively, the slide rail 15 can be a separate component, which is then fixed to the housing 10 by fasteners. There can be one or more slide rails 15. It is understood that when there are multiple slide rails 15, the shape of each slide rail 15 is completely identical.

[0048] The air guide plate 50 is located at the air outlet 12, and its function is to guide the airflow direction. For example, for Figures 1 to 7 In the illustrated embodiment, the air guide plate 50 is a long strip extending horizontally. The air guide plate 50 guides the pitch angle of the airflow from the air outlet 12, that is, adjusts the angle between the airflow direction and the horizontal plane. The air guide plate 50 has at least one sliding portion 51, each sliding portion 51 being disposed within a slide rail 15, i.e., the number of sliding portions 51 is the same as the number of slide rails 15. The sliding portion 51 may be columnar, disposed within the grooved slide rail 15. The sliding portion 51 may be formed on the air guide plate 50; alternatively, the sliding portion 51 may be a separate component, mounted on the air guide plate 50 by fasteners.

[0049] Each swing arm 61 can rotate about a fixed axis at its first end c, and the second end d of the swing arm 61 is rotatably connected to the air guide plate 50. (See reference) Figure 3 and Figure 4For example, the second end d of the swing arm 61 can be provided with a rotating shaft, which can be rotatably installed in the hole of the air guide plate 50 to achieve a rotatable connection. The rotation axes of the first end c and the second end d of the swing arm 61 are both perpendicular to the plane where the slide rail 15 is located.

[0050] The indoor unit of the air conditioner is configured such that by rotating the swing arm 61 about its first end c, the sliding part 51 slides along the slide rail 15, thereby changing the position of the air guide plate 50, for example, driving the air guide plate 50 to... Figures 2 to 7 The locations shown are as follows.

[0051] In this embodiment of the air conditioner indoor unit, by setting a slide rail 15 and a swing arm 61, the movement of the air guide plate 50 is a composite motion of sliding along the slide rail 15 and rotating around its sliding part 51. This composite motion changes the position of the air guide plate 50 to open or close the air outlet 12 and adjust its air guiding angle. The movement mode of the air guide plate 50 in this invention is novel and ingenious, enhancing product differentiation and user experience.

[0052] In some embodiments of the present invention, such as Figures 2 to 7 As shown, the indoor unit of the air conditioner also includes a motor 63. The motor 63 drives the swing arm 61 to rotate around its first end c. The motor 63 can be directly connected to the first end of the swing arm 61 to directly drive its rotation; alternatively, it can be indirectly connected to the first end of the swing arm 61 using a gear or other transmission mechanism. The motor 63 can be a stepper motor.

[0053] Furthermore, in some embodiments, the indoor unit of the air conditioner is configured to allow the air guide vane 50 to reciprocate between a first closed state, an open state, and a second closed state. That is, the air guide vane 50 can move to the above three states, but it does not only have three operating states; the air guide vane 50 can move to states between the three states.

[0054] In the first closed state, such as Figure 2 and Figure 3 The air guide plate 50 blocks the air outlet 12, and the second end d of the swing arm 61 is located between the sliding part 51 and the first end c of the swing arm 61. Figure 3 As shown, at this time, the first end a and the second end b of the air guide plate 50 are located at the upper and lower ends of the adjacent air outlet 12, respectively. When the indoor unit of the air conditioner is in the off state, the air guide plate 50 can be in the first closed state.

[0055] exist Figure 2 In the first closed state shown, motor 63 is allowed to rotate forward. Figures 2 to 7 From the perspective shown, motor 63 rotates clockwise (forward rotation is clockwise, reverse rotation is counterclockwise) to flip the air guide plate 50 to an open state where the air guide plate 50 is parallel to the swing arm 61, that is, from... Figure 2 Status Figure 4The state, eventually moving to Figure 5 The open state is shown. When the air guide plate 50 is in... Figure 4 In the indicated state, it can guide air downwards. The air guide plate 50 is in... Figure 5 When shown in the open state, the air outlet 12 is fully open.

[0056] exist Figure 5 In the open state shown, the motor 63 is allowed to continue rotating forward to cause the sliding part 51 to rotate within the slide rail 15 (at this time, the sliding part 51 no longer slides within the slide rail 15), so that the air guide plate 50 continues to open, resulting in a larger opening angle. Alternatively, the motor 63 can be reversed to cause the sliding part 51 to rotate within the slide rail 15 (at this time, the sliding part 51 no longer slides within the slide rail 15), thereby causing the air guide plate 50 to rotate to the second closed state, blocking the air outlet 12, i.e., from... Figure 5 go through Figure 6 Finally arrived Figure 7 As shown in the diagram, the first end a and the second end b of the air guide plate 50 are located at the lower and upper ends of the adjacent air outlet 12, respectively. The air guide plate 50 is kept in a state between the open state and the second closed state to change the air guiding angle of the air guide plate 50.

[0057] Of course, it is understandable that the air guide plate 50 can reciprocate, that is, the air guide plate 50 can also return from the second closed state to the open state, and then return from the open state to the first closed state.

[0058] The air conditioner indoor unit of this embodiment can not only use the forward rotation of the motor 63 to make the air guide plate 50 reciprocate between the first closed state and the open state, but also use the reverse rotation of the motor 63 to make the air guide plate 50 rotate from the open state to the second closed state. This makes the air guide plate 50 more versatile and the air supply mode of the air conditioner indoor unit more diversified.

[0059] In some embodiments of the present invention, such as Figures 2 to 7 As shown, the indoor unit of the air conditioner is a wall-mounted unit, and the casing 10, air outlet 12, and air guide plate 50 are all long strips extending horizontally. Furthermore, each slide rail 15 extends along the width direction of the air outlet 12.

[0060] More specifically, such as Figures 2 to 7 As shown, the air outlet 12 can be located in the lower front region of the housing 10, and can be further oriented downwards and forwards to widen the air delivery angle. The first end of each swing arm 61 is adjacent to the lower end of the air outlet 12. Thus, when the air guide plate 50 moves to... Figure 4 When the air conditioner is in the indicated state, it can guide air downwards. When the indoor unit is in heating mode, the air guide plate 50 guides air downwards, achieving a downward airflow effect to provide a warm foot experience and prevent hot air from failing to reach the ground. When the air guide plate 50 moves to... Figure 6In the indicated state, it can direct airflow forward or upward, achieving an upward airflow effect. When the indoor unit of the air conditioner is cooling, operating the upward airflow mode can increase the airflow distance and height, allowing the cool air to scatter downwards from a higher point at a distance, resulting in better diffusion.

[0061] In some embodiments, such as Figures 2 to 7 As shown, the rotation axis of the first end c of the swing arm 61 can be located within the slide rail 15, making the structure of the motion mechanism more compact. The second end d of the swing arm 61 is rotatably connected to the central part of the air guide plate 50 in the width direction, for example, the middle 1 / 5 section in the width direction. Each sliding part 51 can be provided at the end of the air guide plate 50 in the width direction, for example, end a. No matter where the air guide plate 50 moves, one end of it is always on the air outlet section of the air outlet 12, so that it can better guide the airflow. When the air guide plate 50 moves to the first closed state, the length direction of the swing arm 61 can be made parallel to the width direction of the air guide plate 50, that is, the sliding part 51 and the two ends of the swing arm 61 are collinear.

[0062] In some embodiments, such as Figures 2 to 7 As shown, each slide rail 15 can extend in a straight line at least in the section that mates with the sliding part 51, so that the movement of the air guide plate 50 is smoother and less strenuous during the forward and reverse rotation of the motor 63.

[0063] In some embodiments, there are two slide rails 15 and two sliding parts 51. The two slide rails 15 are respectively formed on the two transverse sidewalls of the housing 10, and the two sliding parts 51 are respectively located at both ends of the air guide plate 50 in the length direction.

[0064] The number of motors 63 and swing arms 61 can be one, which can be set at one end of the length direction near the air guide plate 50 to facilitate the control of motor 63.

[0065] In some embodiments, such as Figure 2 As shown, a heat exchanger 30 and a fan 40 can be installed inside the casing 10. An air inlet can be provided at the top of the casing 10. The heat exchanger 30, the throttling device, and the compressor, condenser, and other refrigeration components located in the outdoor unit of the air conditioner are connected via pipes to form a vapor compression refrigeration cycle system. Under the action of the fan 40, indoor air enters the interior of the casing 10 through the air inlet, completes forced convection heat exchange with the heat exchanger, forms heat exchange air, and enters the air duct 20. Then, it is blown into the room through the air outlet 12 of the casing 10 to regulate the indoor air. The fan 40 is preferably a cross-flow fan with its axis parallel to the length direction of the casing 10, and it is located at the inlet of the air duct 20. The heat exchanger 30 can be a three-stage heat exchanger.

[0066] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
