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] Generally speaking, the air outlet of an air conditioner indoor unit is usually equipped with air guide plates, louvers, air guide grilles, and other air outlet structures, the main function of which is to guide the direction of airflow from the outlet.

[0003] The existing indoor air conditioning units largely adopt the above-mentioned air outlet structure, which makes them similar in terms of user experience and product appearance, making it difficult to improve the product's quality.

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

[0005] The purpose of this invention is to overcome at least one defect in the prior art and provide a wall-mounted air conditioner indoor unit with a novel air outlet structure to enrich the air outlet modes, enhance product differentiation, and improve the user experience.

[0006] A further objective of this invention is to enable the air conditioner to have an intermittent air supply mode, thereby improving the user's airflow experience.

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

[0008] The casing has an air outlet; and

[0009] Multiple air outlet columns are arranged axially side-by-side at the air outlet. Each air outlet column has multiple air outlet sections, each of which is used to guide the airflow direction or process the airflow.

[0010] Each of the air outlet columns is configured to rotate independently and controllably about an axis parallel to its axis to adjust the relative position of each of its air outlets and the air outlet, so as to change the air outlet mode of the indoor unit of the air conditioner.

[0011] Optionally, each of the plurality of air outlets in the air outlet column includes at least one purification plate and at least one air guide plate, each purification plate being configured to purify the airflow passing through it, and the air guide plate being used to guide the direction of the airflow.

[0012] Optionally, the number of purification plates in each air outlet column is multiple and they are arranged at circumferential intervals along the air outlet column; and

[0013] The air guide plate of each of the air outlet columns is disposed on the inner side of the outer periphery of the air outlet column.

[0014] Optionally, each of the air outlet columns has two purification plates, and the air guide plate is located between the two purification plates.

[0015] Optionally, each of the air outlet columns further includes a columnar frame for mounting the plurality of air outlets, the columnar frame comprising:

[0016] Two discs respectively form the two axial ends of the air outlet column;

[0017] Multiple connecting strips are respectively connected between the two disc bodies and arranged at intervals along the circumference of the air outlet column; and

[0018] A mandrel is connected between the centers of the two discs, and both ends of the mandrel are rotatably mounted to the housing.

[0019] Optionally, in each of the air outlet columns, each of the purification plates is connected between two adjacent connecting strips, one side of the air guide plate in the width direction is connected to the spindle, and the other end is connected to one of the connecting strips.

[0020] Optionally, the indoor unit of the air conditioner further includes: a plurality of drive mechanisms, each of the drive mechanisms being used to drive one of the air outlet columns to rotate intermittently.

[0021] Optionally, each of the drive mechanisms includes a motor and a rotating component, the rotating component being driven by the motor to rotate around a fixed axis and having a pushing portion spaced apart from the rotating axis;

[0022] Each of the air outlet columns has a plurality of guide grooves arranged circumferentially on its first end face. Each guide groove extends radially along the first end face and has a first end near the center of the first end face and a second end near the periphery of the first end face. The first end has an opening.

[0023] Each of the drive mechanisms is configured such that, when the motor drives the rotating member to rotate, the pushing part enters the guide groove from the opening of one of the guide grooves, moves along the guide groove toward the second end to push the air outlet column to rotate, and when the line connecting the rotating shaft and the pushing part is parallel to the length direction of the guide groove, the pushing part changes direction and moves toward the first end to push the air outlet column to continue rotating, and after the pushing part leaves the guide groove through the opening, the air outlet column stops rotating, and when the rotating member continues to rotate to allow the pushing part to enter the next guide groove, it pushes the air outlet column to continue rotating.

[0024] Optionally, the rotating member includes:

[0025] Linkage section;

[0026] The rotating shaft and the pushing part extend from opposite ends of the connecting rod portion, respectively; and

[0027] The counterweight is connected to one end of the connecting rod where the rotating shaft is located.

[0028] Optionally, the indoor unit of the air conditioner is wall-mounted;

[0029] The air outlet is a long strip with its length parallel to the horizontal direction; and

[0030] The axial direction of each of the air outlet columns is parallel to the horizontal direction.

[0031] The air conditioner indoor unit of this invention includes multiple rotatable air outlet columns. Each air outlet column includes multiple air outlet sections, which makes the air outlet modes of the air conditioner indoor unit more diverse. When an air outlet column rotates, it changes the relative positions of its various air outlet sections and the air outlet, so that some air outlet sections face the air outlet to act on the airflow, and other air outlet sections are no longer directly facing the air outlet. In this way, the air outlet mode can be changed by rotating the air outlet column to meet the diverse needs of users. Furthermore, since multiple air outlet columns are provided at the air outlet, the type, number, size, arrangement, or phase of the air outlet sections of each air outlet column can be designed differently, so that different areas of the air outlet can be supplied with air in different modes at the same time, achieving a zoned multi-mode air supply effect. Compared with traditional air guide structures such as air deflectors and louvers, the air outlet structure of this invention is novel and ingenious, with higher product differentiation, and it also revolutionizes the appearance of the air conditioner indoor unit, making the product more upscale and providing a better user experience.

[0032] Furthermore, in the indoor unit of the air conditioner of the present invention, the drive mechanism can drive the air outlet column to rotate intermittently, improving the user's airflow experience. When the motor of the drive mechanism rotates continuously, the air outlet column rotates intermittently, that is, it rotates once and then stops. During the periods when it stops rotating, the air outlet column maintains the current airflow mode, thus having enough time to fully utilize the function of the current airflow mode, avoiding the continuous rotation of the air outlet column, which would cause the airflow mode to switch too quickly and prevent some airflow modes from fully utilizing their functions and advantages.

[0051] 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. The air conditioner can consist of an evaporator, condenser, compressor, throttling device, and other necessary components forming a vapor compression refrigeration cycle system, which outputs cool / hot air via a fan to achieve cooling and heating of the indoor environment. Specifically, the indoor unit can be wall-mounted, floor-standing, or other types. Figures 1 to 6 The illustrated indoor unit is a wall-mounted air conditioner.

[0052] Figure 1 This is a schematic diagram of the structure of an air conditioner indoor unit according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic front view of the indoor unit of the air conditioner shown; Figure 3 yes Figure 2 Enlarged NN sectional view of the indoor unit of the air conditioner;

[0053] Figure 4 yes Figure 3 The diagram shows the indoor unit of the air conditioner after the air outlet column has been rotated 90° clockwise. Figure 5 yes Figure 4 The diagram shows the indoor unit of the air conditioner after the air outlet column 50 is rotated 90° clockwise. Figure 6 yes Figure 5 The diagram shows the indoor unit of the air conditioner after the air outlet column 50 is rotated 90° clockwise. Figure 7 yes Figure 1 A schematic diagram of the structure of the two air outlet columns. Figures 3 to 6 Only the area near air outlet 12 was cut open; other areas were not cut open.

[0054] like Figures 1 to 7 As shown, the indoor unit of the air conditioner in this embodiment of the invention generally includes a housing 10 and a plurality of air outlet columns 50.

[0055] The housing 10 has an air outlet 12 for delivering regulated airflow generated by the air conditioner to the indoor environment for regulating indoor air. The regulated airflow can be one or more of the following: cold air, hot air, fresh air, and purified air. An air duct 15 can be formed inside the housing 10, and the outlet of the air duct 15 is connected to the air outlet 12.

[0056] Multiple air outlet columns 50 are arranged axially side-by-side at the air outlet 12. That is, the multiple air outlet columns 50 are arranged side-by-side, and their axes are parallel or collinear to form an "axially parallel" arrangement. The air outlet columns 50 are generally columnar, specifically cylindrical, elliptical, polygonal, etc. The installation orientation of the air outlet columns 50 is related to the shape of the air outlet 12. For example, for a floor-standing air conditioner indoor unit, the air outlet 12 can be a vertical strip, in which case the air outlet columns 50 can be installed vertically. For a wall-mounted air conditioner indoor unit, such as... Figure 1 and Figure 2 If the air outlet 12 is made into a horizontal strip, then the air outlet column 50 extends in the horizontal direction.

[0057] Each air outlet column 50 has multiple air outlets 200, each of which is used to guide the airflow or process the airflow. The processing of the airflow includes various methods such as purification, humidification, and aromatherapy.

[0058] Each air outlet column 50 is configured to rotate independently and controllably about an axis (x1) parallel to its axial direction (x direction) to adjust the relative position of each air outlet 200 and the air outlet 12, so as to change the air outlet mode of the indoor unit of the air conditioner.

[0059] The indoor unit of the air conditioner in this embodiment of the invention includes multiple rotatable air outlet columns 50. Each air outlet column 50 includes multiple air outlet sections 200, which makes the air outlet modes of the indoor unit more diverse. When an air outlet column 50 rotates, the relative positions of its various air outlet sections 200 and the air outlet 12 are changed, so that some air outlet sections 200 face the air outlet 12 to act on the airflow, and other air outlet sections 200 are no longer directly facing the air outlet 12. In this way, the air outlet mode can be changed by rotating the air outlet column 50 to meet the diverse needs of users. Suppose that the air outlet section 200 of each air outlet column 50 includes an air outlet section for purification and an air outlet section for guiding airflow. When the air outlet column 50 rotates until the air outlet section used for purification faces the air outlet 12, the air outlet section fully exerts its purification function, and the indoor unit of the air conditioner is in purification mode. When the air outlet column 50 rotates to face the air outlet 12, the air outlet section used for air guidance fully exerts its air guiding function, directing the airflow to the preset area, so that the indoor unit of the air conditioner is in the air supply mode.

[0060] Furthermore, since multiple air outlet columns 50 are installed at the air outlet 12, the type, quantity, size, arrangement, or phase of the air outlet section 200 of each air outlet column 50 can be designed differently. This allows different areas of the air outlet 12 to simultaneously supply air in different modes, achieving a zoned multi-mode air supply effect. For example, for a wall-mounted air conditioner indoor unit, in Figure 1 In this state, the left air outlet column 50 is in air supply mode, and the right air outlet column 50 is in purification mode.

[0061] Compared to traditional air guide structures such as air deflectors and louvers, the air outlet structure of this invention is novel and ingenious, with higher product differentiation. It also revolutionizes the appearance of air conditioner indoor units, making the product more upscale and providing a better user experience.

[0062] In some embodiments, each air outlet column 50 has multiple air outlets 200 including at least one purification plate 210 and at least one air guide plate 220. Each purification plate 210 is configured to purify the airflow passing through it, and the air guide plate 220 is used to guide the airflow direction. Specifically, as... Figure 2 As shown, the number of purification plates 210 in each air outlet column 50 can be multiple and arranged at intervals along the circumference of the air outlet column 50. The air guide plate 220 of each air outlet column 50 is positioned inside the outer periphery of the air outlet column 50 to avoid interference with the housing 10 when the air outlet column 50 rotates. For example, each air outlet column 50 can have two purification plates 210, with the air guide plate 220 located between the two purification plates 210. With this configuration, by adjusting the position of the air outlet column 50, the wall-mounted air conditioner indoor unit can have at least the following air supply modes.

[0063] (1) Cooling and Air Supply Mode: This mode can be selected when the indoor unit of the air conditioner is in cooling mode. Specifically, the air outlet column 50 is positioned at... Figure 3 and Figure 4 Any state between, or in Figure 3 and Figure 4 The airflow is oscillating back and forth between the two air purification plates 210. This allows the two purification plates 210 to be positioned close to the two walls of the air duct 15, so that they no longer directly block the air outlet 12. This allows the space between the two purification plates 210 to be used for air outlet, minimizing the resistance of the airflow to the purification plates 210.

[0064] (2) Cooling and Purification Mode: This mode can be selected when the indoor unit of the air conditioner is in cooling mode. Specifically, the air outlet column is positioned at 50°. Figure 4 Or in a nearby state, the two purification plates 210 block the air outlet 12 from the front, and the air guide surface of the air guide plate 220 faces upward, so that the main body of the airflow must pass through the two purification plates 210 in sequence and be purified by them.

[0065] (3) Heating and Air Supply Mode: This mode can be selected when the indoor unit of the air conditioner is in heating mode. Specifically, the air supply column 50 is positioned at... Figure 5 and Figure 6 Any state between, or in Figure 5 and Figure 6 The air oscillates back and forth between the two air purification plates 210. This positions the two purification plates 210 close to the two walls of the air duct 15, preventing them from directly obstructing the air outlet 12. The air guide surface of the guide plate 220 faces backward to guide the air downward. The space between the two purification plates 210 is used for air outlet, minimizing the resistance of the airflow from the purification plates 210.

[0066] (3) Heating and Purification Mode: This mode can be selected when the indoor unit of the air conditioner is in heating mode. Specifically, the air outlet column is positioned at 50°. Figure 6 Or in a nearby state, the two purification plates 210 block the air outlet 12 from the front, and the air guide surface of the air guide plate 220 faces downward, so that the main body of the airflow must pass through the two purification plates 210 in sequence and be purified by them.

[0067] In some embodiments, such as Figures 1 to 6 As shown, the indoor unit of the air conditioner is wall-mounted. The air outlet 12 is a long strip parallel to the horizontal direction. The axis of each air outlet column 50 is parallel to the horizontal direction. Multiple air outlet columns 50 are arranged horizontally. For example, the number of air outlet columns 50 can be two, and a human sensor can be installed on the indoor unit to detect the distribution of people in the room and send the signal to the air conditioner controller.

[0068] A preferred control logic is as follows: If the controller receives a signal indicating that there is no human presence indoors, after the indoor temperature reaches the set temperature, it controls each air outlet column 50 to rotate to purification mode. If a signal indicates that there is a human presence indoors, the controller asks the user whether to activate the purification mode. If the user confirms activation, it determines whether the human is located on the left or right side of the air conditioner, and controls the air outlet column corresponding to the area where the human is located to switch to purification mode, while the air outlet columns corresponding to areas without a human presence enter air supply mode. If the user confirms that the purification mode is not activated, it determines whether the human is located on the left or right side of the air conditioner, and controls the air outlet column corresponding to the area where the human is located to switch to air supply mode, while the air outlet columns corresponding to areas without a human presence enter purification mode.

[0069] Figure 8 yes Figure 7 A schematic diagram of the solution for one of the air outlet columns; Figure 9 yes Figure 8 Enlarged view of point A.

[0070] In some embodiments, such as Figure 8 and Figure 9 As shown, each air outlet column 50 may also include a columnar frame 100 for mounting multiple air outlet sections 200. The columnar frame 100 includes two discs 110 and 120, multiple connecting strips 130, and a spindle 150. The two discs 110 and 120 respectively form the two axial ends of the air outlet column 50, and the outer end face of one of the discs 110 forms the aforementioned first end face 108. The multiple connecting strips 130 are respectively connected between the two discs 110 and 120 and are arranged at intervals along the circumference of the air outlet column 50. The spindle 150 is connected between the centers of the two discs 110 and 120. The two ends of the spindle 150 are rotatably mounted to the housing 10.

[0071] Each purification plate 210 is connected between two adjacent connecting strips 130. (Reference) Figure 3 and Figure 8 This allows for a total of four connecting strips 130 and two purification plates 210. Two connecting strips 130 are used to mount one purification plate 210, and the remaining two connecting strips 130 are used to mount the other purification plate 210. One side of the air guide plate 220 in the width direction is mounted to the spindle 150, and the other side is fixed to one of the connecting strips 130.

[0072] like Figure 9As shown, the discs 110 and 120 constituting the first end face include an outer ring 111 and a central disc 117 located inside the outer ring 111. Each radial rod 112, 113, 114, and 115 is connected between the outer ring 111 and the central disc 117. A plate 118 is provided between two adjacent radial rods. The outer edge of the plate 118 is connected to the outer ring 111, and the inner edge is an arc-shaped edge. The counterweight 720 can be a fan-shaped structure, with its edge away from the rotation axis 730 being arc-shaped and its diameter being smaller than the inner diameter of the plate 118.

[0073] In some embodiments, the indoor unit of the air conditioner further includes multiple drive mechanisms 53, each drive mechanism 53 driving an air outlet column 50 to rotate intermittently. Thus, when the motor 600 of the drive mechanism 53 rotates continuously, the air outlet column 50 rotates intermittently, that is, it rotates once and then stops. During the periods when it stops rotating, the air outlet column 50 maintains the current air outlet mode, thereby allowing sufficient time to fully utilize the current air outlet mode and preventing the continuous rotation of the air outlet column 50 from causing abrupt switching of the air outlet mode, which would prevent some air outlet modes from fully utilizing their functions and advantages.

[0074] Figure 10 This is a schematic diagram of the end face structure of the air outlet column 50; Figure 11 yes Figure 10 The diagram shows the air outlet column 50 when the pusher 713 is about to enter the guide groove 101; Figure 12 yes Figure 11 The diagram shows the air outlet column 50 when the pushing part 713 enters the guide groove 101 and the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101. Figure 13 yes Figure 12 The diagram shows the air outlet column 50 moving in the opposite direction from the pusher 713 to the first end of the guide groove 101.

[0075] like Figure 8 and Figure 9 As shown, each drive mechanism 53 may specifically include a motor 600 and a rotating member 700. The rotating member 700 is driven by the motor 600 to rotate around a fixed axis and has a pushing portion 713 spaced apart from the rotating shaft 730. The pushing portion 713 is preferably a columnar structure parallel to the rotating shaft 730. Alternatively, it may be spherical or other shapes. The first end face 108 of the air outlet column 50 is provided with a plurality of guide grooves 101 arranged circumferentially thereon. Each guide groove 101 extends radially along the first end face 108 and has a first end E1 near the center of the first end face 108 and a second end E2 near the periphery of the first end face 108. The first end E1 has an opening 102.

[0076] Each drive mechanism 53 is configured such that when the motor 600 drives the rotating member 700 to rotate, the pushing part 713 enters the guide groove 101 through the opening 102 of the guide groove 101 and moves along the guide groove 101 toward the second end E2 to push the air column 50 to rotate. When the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101, the pushing part 713 changes direction and moves toward the first end E1 to push the air column 50 to continue rotating. After the pushing part 713 leaves the guide groove 101 through the opening 102, the air column 50 stops rotating. When the rotating member 700 continues to rotate so that the pushing part 713 enters the next guide groove 101, the air column 50 is pushed to continue rotating.

[0077] The following is for reference. Figures 10 to 11 The above process will be explained in detail.

[0078] like Figure 10 As shown, the air outlet column 50 includes four guide grooves 101, which are formed on the four radial rods 112, 113, 114, and 115 of the air outlet column 50, respectively, with each adjacent guide groove 101 spaced 90° apart. Figure 10 In the indicated state, the rotating member 700 rotates clockwise, causing the pushing part 713 to disengage from the guide groove 101 of the radial rod 114. Then it rotates to... Figure 11 Status. In Figures 10 to 11 Between states, rotating component 700 rotates, but the air outlet column 50 does not rotate. Rotating component 700 reaches... Figure 11 After reaching the desired state, the rotation continues, causing the pushing part 713 to enter the guide groove 101 of the radial rod 113 through the opening 102 at the first end E1. As it continues to rotate clockwise, it pushes one wall of the guide groove 101, thereby causing the air column 50 to rotate clockwise. During this process, the pushing part 713 gradually approaches the second end E2 until... Figure 12 The state is such that the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101. At this time, the rotating member 700 continues to rotate clockwise, the pushing part 713 turns and moves towards the first end E1, and continues to push the groove wall of the guide groove 101, thereby causing the air column 50 to rotate clockwise until... Figure 13 The state.

[0079] exist Figure 13 In the current state, the rotating component 700 continues to rotate clockwise, causing the pushing part 713 to disengage from the guide groove 101 of the radial rod 113 and then enter the guide groove 101 of the radial rod 112, repeating the above process. Because four guide grooves 101 are provided, the air outlet column 50 rotates 90° when the rotating component 700 rotates one revolution. The air outlet column 50 pauses four times during one revolution. This embodiment cleverly utilizes the above structure to achieve intermittent rotation of the air outlet column 50 driven by the continuously rotating rotating component 700. Of course, the number of guide grooves 101 is not limited to four and can be more.

[0080] In some embodiments, such as Figure 9 As shown, the rotating component 700 includes a connecting rod portion 710, a rotating shaft 730, a pushing portion 713, and a counterweight portion 720. The connecting rod portion 710 is rod-shaped. The rotating shaft 730 and the pushing portion 713 extend from both ends of the connecting rod portion 710 in opposite directions, so that the rotating component 700 is located between the motor 600 and the guide groove 101, with the rotating shaft 730 and the pushing portion 713 extending toward the motor 600 and the guide groove 101, respectively. The counterweight portion 720 is connected to the end of the connecting rod portion 710 where the rotating shaft 730 is located, in order to increase the rotational inertia and structural strength of the rotating component 700, making the rotation of the rotating component 700 more stable. Specifically, the connecting rod portion 710, the rotating shaft 730, the pushing portion 713, and the counterweight portion 720 can be formed as an integrally molded part.

[0081] 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.
