Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to an air guide mechanism for an air conditioner that facilitates structural simplification and an air conditioner having the air guide mechanism. Background Technology

[0002] To improve airflow range, air conditioner indoor units often have swingable air deflectors installed in their air outlets and ducts. Currently, most air deflectors are motor-driven, although some can be manually adjusted by the user. While manual adjustment requires no electricity, the lack of continuous power input prevents automatic reciprocating airflow. Motor-driven deflectors, on the other hand, require electrical components, necessitating the design and operation of driver programs and internal wiring, which hinders production efficiency and introduces potential electrical hazards. Summary of the Invention

[0003] The primary objective of this invention is to provide an air guide mechanism for an air conditioner that is directly driven by the pressure difference of the compressor, which eliminates the need for electrical components, simplifies the product structure, and removes potential electrical problems.

[0004] The second objective of this invention is to provide an air conditioner that directly utilizes the pressure difference of the compressor to drive the air guide plate.

[0005] The air guiding mechanism of the air conditioner provided by the first objective of the present invention includes an air guide plate; the air guiding mechanism of the air conditioner also includes a pneumatic device and an air conditioner compressor; the compressor drives the pneumatic device, and the pneumatic device drives the air guide plate to swing.

[0006] A further design includes a pneumatic device with an output end and a guide vane linked to the output end; the high-pressure port of the compressor is connected to the first chamber of the pneumatic device, and the low-pressure port of the compressor is connected to the second chamber of the pneumatic device; the output end moves due to the pressure difference between the first and second chambers.

[0007] As can be seen from the above solution, this invention utilizes a compressor to drive the air guide plate, achieving the opening and closing of the air guide plate without the need for a motor. The air guide plate opens when there is a pressure difference across the pneumatic device, and its opening angle changes with the pressure difference. When the air conditioner is first started, the pressure difference increases, and the opening angle of the air guide plate gradually increases. During stable operation, the pressure difference remains constant, and the air guide plate angle remains fixed, resulting in stable airflow. When the air conditioner is turned off, the pressure difference gradually decreases, causing the air guide plate to gradually retract, eventually closing. Furthermore, during air conditioner operation, the air guide plate can also oscillate according to the different operating states of the compressor (resulting in different pressure differences), thus achieving air sweeping. Therefore, this invention directly utilizes the compressor's pressure difference to drive the air guide mechanism of the air conditioner, eliminating the need for electrical components, simplifying the product structure, and eliminating potential electrical problems.

[0008] A further proposed solution is to include a pneumatic device comprising a linear cylinder with a piston rod at the output end.

[0009] As can be seen from the above, when a linear cylinder is used in the pneumatic device, a smaller and thinner linear cylinder can be obtained at a lower cost and installed in the indoor unit to drive the air guide plate, thus avoiding the impact on the product size due to the installation of the pneumatic device.

[0010] A further proposed solution is to fix the cylinder body of the linear cylinder.

[0011] As can be seen above, although the linear cylinder is used to drive the air guide plate to swing, since the linear cylinder and the compressor are connected by a pipeline and high-pressure gas flows between them, in order to ensure safety, the cylinder body of the linear cylinder is fixed in the indoor unit. This can prevent the linear cylinder and the pipeline from being in a moving state and eliminate the safety hazards caused by the cylinder or pipeline becoming loose or broken.

[0012] A further embodiment is that the air guide plate includes a first swing arm and a second swing arm located on opposite sides of the first center line, and a slider is provided on the air guide plate at the location of the first center line; the air guiding mechanism of the air conditioner also includes a fixed fixing component, which is provided with a sliding groove, and the sliding groove is inclined to the piston rod on the axial projection of the first center line; the piston rod is rotatably connected to the air guide plate, and the slider cooperates with the sliding groove.

[0013] As can be seen from the above, a further problem is that the cylinder body of the linear cylinder is fixedly set. That is to say, although the position of the second centerline where the piston rod and the guide plate are rotatably connected changes vertically with the up and down movement of the piston rod, the position of the second centerline does not change horizontally. However, the length of the lever arm formed by the first centerline and the second centerline is constant. During the downward swing of the first swing arm, the horizontal distance between the first centerline and the second centerline will change, and this change in distance follows a certain pattern. Therefore, the first centerline needs to be set to be movable along a certain trajectory, that is, the slider on the first centerline needs to be movable along a certain trajectory, and the slide groove needs to be set according to the above trajectory. To this end, in this invention, the slide groove is set to extend downward at an angle closer to the second centerline. With this setting, the first centerline has a certain amount of movement space in both the horizontal and vertical directions, which can adapt to the changes after the vertical movement of the second centerline. The position of the first centerline L1 changes with the swing of the guide plate.

[0014] Another further solution is to install a control valve on the pipeline connecting the compressor and the pneumatic device.

[0015] As can be seen from the above, in this configuration, control valves are installed on the first pipeline connecting the high-pressure port of the compressor and the first chamber of the pneumatic device, and on the second pipeline connecting the low-pressure port of the compressor and the second chamber of the pneumatic device. The corresponding control valves can control the opening and closing of the first pipeline or adjust the opening degree of the first pipeline, and the corresponding control valves can control the opening and closing of the second pipeline or adjust the opening degree of the second pipeline. This configuration makes the pressure difference controllable, and the user can control the swing angle of the air guide plate by remote control.

[0016] The second objective of this invention is to provide an air conditioner that includes the aforementioned air guiding mechanism.

[0017] As can be seen from the above solution, the air conditioner of the present invention eliminates the motor and directly uses the existing compressor to drive the air guide plate. The air guide plate can be opened and closed without a motor. The air guide plate opens when there is a pressure difference across the two ends of the pneumatic device. The opening angle of the air guide plate changes with the pressure difference. When the air conditioner is first started, the pressure difference increases, and the opening angle of the air guide plate gradually increases. When running stably, the pressure difference remains constant, and the angle of the air guide plate remains fixed, resulting in stable airflow. When the air conditioner is turned off, the pressure difference gradually decreases, causing the air guide plate to gradually retract, eventually closing. Furthermore, during air conditioner operation, the air guide plate can also oscillate according to the different operating states of the compressor (resulting in different pressure differences), thereby achieving air sweeping. Therefore, the air guide mechanism of the air conditioner directly driven by the pressure difference of the compressor in this invention can eliminate the need for electrical components, simplify the product structure, and eliminate potential electrical problems.

[0018] A further embodiment includes a first heat exchanger, a second heat exchanger, and a throttling element, with the compressor, the first heat exchanger, the throttling element, and the second heat exchanger connected in sequence; a pipeline connecting the compressor and the first heat exchanger is branched off and connected to a pneumatic device, and / or, a pipeline connecting the compressor and the second heat exchanger is branched off and connected to a pneumatic device.

[0019] As can be seen from the above, this configuration allows the air guiding mechanism of the present invention to be built on the basis of the existing compression system, and can be realized by connecting to the original compression system of the air conditioner through the pipeline, minimizing the addition of additional components and simplifying the design and component layout.

[0020] A further option is that the air conditioner includes an indoor unit, the indoor unit includes an air outlet, and at least two air deflectors are installed at the air outlet.

[0021] A further proposed solution is to have two air guide vanes positioned opposite each other, with the center lines around which the two air guide vanes swing parallel to each other, and the two air guide vanes jointly blocking the air outlet; or, the center lines around which the two air guide vanes swing are not on the same plane.

[0022] A further proposed solution is to have each air deflector driven by its corresponding pneumatic device.

[0023] As can be seen from the above, setting at least two air guide vanes can meet the different airflow requirements of the indoor unit's air outlet. For example, when the center lines around which the two air guide vanes swing are not on the same plane, it can meet the needs of vertical and horizontal airflow, as well as situations requiring airflow to be directed straight forward and straight down, or situations where a column-type cabinet air conditioner requires air guide vanes similar to those on a double-door design. Preferably, each air guide vane is independently controllable, which can improve the freedom and accuracy of adjusting the airflow pattern, further meeting user needs. Attached Figure Description

[0037] First embodiment of air conditioner

[0038] See Figure 1 and Figure 8 , Figure 1 This diagram shows a side view of the indoor unit 1 of the air conditioner of the present invention. Figure 8 This diagram illustrates the connection of the air conditioning system of the present invention. The indoor unit 1 is a wall-mounted unit with its air outlet 100 facing downwards. The indoor unit 1 includes a casing 11, fan blades 12, an air guide plate 13, a linear cylinder 2, and a fixing component 3. The linear cylinder 2 is the pneumatic device of the present invention. The air conditioning system includes a compressor 91, a condenser 92, a throttling element 93, and an evaporator 94 connected in sequence. The system also includes a first pipe 81 connected between the high-pressure port of the compressor 91 and the condenser 92, and a second pipe 82 connected between the low-pressure port of the compressor 91 and the evaporator 94. The first pipe 81 and the second pipe 82 are respectively a high-pressure pipe and a low-pressure pipe. The condenser 92 is the first heat exchanger of the present invention, and the evaporator 94 is the second heat exchanger of the present invention; the evaporator 94 is disposed within the indoor unit 1.

[0039] Mainly, this invention does not use separate electrical components to drive the air guide plate 13. Instead, it utilizes the compressor 91 to drive the linear cylinder 2, which in turn drives the air guide plate 13 to swing. See also Figure 1 In this embodiment, two air guide plates 13 are arranged opposite to each other on the front and rear sides of the air outlet 100 and together block the air outlet 100. The indoor unit 1 is provided with two sets of fixing parts 3 and linear cylinder 2 that are respectively linked and cooperate with the two air guide plates 13.

[0040] See Figure 2 The linear cylinder 2 includes a cylinder body 21 and a piston rod 22. Within the cylinder body 21, a first chamber 201 and a second chamber 202 are formed on the front and rear sides of the piston rod 21, respectively. (See also...) Figure 2 and Figure 8The first pipeline 81 includes a first main pipeline 810 and two first branch pipelines 811 for branching. The second pipeline 82 includes a second main pipeline 820 and two second branch pipelines 821 for branching. The first pipeline 81 is connected to the high-pressure port of the compressor 91, while the second pipeline 82 is connected to the low-pressure port of the compressor. The first main pipeline 810 is connected to the condenser 92, and the second main pipeline 820 is connected to the evaporator 94. The two first branch pipelines 811 are respectively connected to the first chamber 201 of the two linear cylinders 2, and the two second branch pipelines 821 are respectively connected to the second chamber 202 of the two linear cylinders 2. When the pressure difference between the first chamber 201 and the second chamber 202 exceeds a certain value, the piston rod 22 can extend outward from the cylinder body 21; when the pressure difference between the first chamber 201 and the second chamber 202 is maintained at a certain value, the piston rod 22 is stable in a certain position; and when the pressure difference between the first chamber 201 and the second chamber 202 is less than a certain value, the piston rod 22 retracts into the cylinder body 21.

[0041] See Figure 3 The air guide plate 13 is provided with a slider 1301 and a short shaft 1302. In this embodiment, the slider 1301 is also configured as a short shaft. The slider 1301 is located at the position of the first center line L1, and the short shaft 1302 is located at the position of the second center line L2. Figure 3 In the side view shown, the air guide plate 13 includes a first swing arm portion 131 and a second swing arm portion 132 located on opposite sides of the first center line L1, a second center line L2, and a short shaft 1302 disposed on the second center line L2 at a position on the first swing arm portion 131 away from the first center line L1. The first swing arm portion 131 and the second swing arm portion 132 do not refer to being shaped like arms, but rather, when considered as objects of motion analysis, they are located on opposite sides of the first center line L1 and are thus regarded as having arm-like functions.

[0042] Additionally, see Figure 4 The lower end of the fastener 3 is provided with a sliding groove 30 that is inclined to the horizontal direction. Figure 4 On the axial projection of the first centerline L1 shown, the groove 30 is inclined to the piston rod 22; see also Figure 5 The piston rod 22 has a shaft hole 220 at its extended end.

[0043] See Figures 1 to 5 In this embodiment, both the linear cylinder 2 and the fixing member 3 are vertically fixed inside the indoor unit 1. The piston rod 22 of the linear cylinder 2 extends downward, the slider 1301 is placed in the slide groove 30, and the short shaft 1302 is rotatably engaged with the shaft hole 220. (Comparison) Figure 2 and Figure 6When the linear cylinder 2 operates due to the change in the chamber ratio of the first chamber 201 and the second chamber 202, causing the piston rod 22 to move downwards, the first center line L1 is considered as the center line around which the air guide plate 13 swings. The first swing arm 131 and the second swing arm 132 are located on opposite sides of the first center line L1. When the piston rod 22 drives the second swing arm 132 to swing downwards, the first swing arm 131 will swing upwards. (Comparison) Figure 1 and Figure 7 When the two first swing arms 131 on both sides swing upward, the previously blocked air outlets 100 will open and air will be discharged under the guidance of the air guide plate 13.

[0044] Among them, see Figure 1 and Figure 7 In this embodiment, under this configuration, the fixed linear cylinder 2 is closer to the inner edge of the housing 11 of the indoor unit 1 than components such as the fixing part 3, the fan blade 12 and the evaporator 94. This can minimize the impact on the configuration and operation of key components such as the fan blade 12 and the evaporator 94.

[0045] A further problem is that, while the cylinder body 21 of the linear cylinder 2 is fixed, the position of the second center line L2 changes vertically with the up-and-down movement of the piston rod 22, but not horizontally. However, the lever arm length formed by the first center line L1 and the second center line L2 is constant. During the downward swing of the first swing arm 131, the horizontal distance between the first center line L1 and the second center line L2 changes, and this change follows a certain pattern. Therefore, the first center line L1 needs to be movable along a certain trajectory; that is, the slider 1301 on the first center line L1 needs to be movable along a certain trajectory, and the slide groove 30 needs to be set according to the aforementioned trajectory.

[0046] Therefore, in this invention, the slide 30 is set to extend downward at an angle close to the second center line L2. With this setting, the first center line L1 has a certain amount of room to move in both the horizontal and vertical directions, which can adapt to the changes after the second center line L2 moves vertically. The position of the first center line L1 changes with the swing of the air guide plate 13.

[0047] Comparison Figure 2 and Figure 6 , Figure 2 In the state shown, slider 1301 is at the upper left end of slide groove 30. Figure 6 In this state, slider 1301 is located at the lower right end of slide groove 30.

[0048] See Figure 8In this embodiment, a corresponding control valve 71 is provided on each of the two second diversion pipelines 821. The pressure difference between the first chamber 201 and the second chamber 202 can be adjusted by controlling the opening degree of the 71, so that the swing angle of the two air guide plates 13 can be controlled and determined respectively.

[0049] Second embodiment of air conditioner

[0050] See Figure 9 In this embodiment, the control valve 72 is installed on the manifold section 832 of the two second branch pipes 831. With this configuration, the pressure difference between the first chamber and the second chamber of the two linear cylinders can be adjusted simultaneously by controlling the opening degree of the control valve 71, thereby making the swing angle of the two guide vanes change synchronously.

[0051] Third embodiment of air conditioner

[0052] See Figure 10 Unlike the first embodiment, the position of the first centerline L1 is fixed, while the second centerline L2 has vertical and horizontal space for movement. Specifically, in this embodiment, the air guide plate 61 is provided with a short shaft 6101 at the first centerline L1, the extended end of the first swing arm is provided with a groove 6102 inclined to the horizontal direction, the extended end of the piston rod 62 is provided with a slider 620, and the lower end of the fixing member 63 is provided with a shaft hole 630. The short shaft 6101 is rotatably connected to the shaft hole 630, and the slider 620 is placed in the groove 6102. With this configuration, the position of the centerline around which the air guide plate 61 swings, i.e., the first centerline L1, is fixed.

[0053] Fourth embodiment of air conditioner

[0054] See Figure 11 In this embodiment, the short shaft 650 on the piston rod 65 of the linear cylinder is rotatably connected to the short shaft 650 on the air guide plate 64 located at the first centerline L1, while the slider 660 at the lower end of the fixing member 66, located at the second centerline L2, is placed in the groove 6402 located at the extension end of the first extension arm. With this configuration, the position of the centerline around which the air guide plate 64 swings, i.e., the first centerline L1, is fixed.

[0055] Fifth embodiment of air conditioner

[0056] See Figure 12 and Figure 13 In this embodiment, the indoor unit 67 of the air conditioner is a wall-mounted unit, and the air outlet 670 of the wall-mounted unit is located at the lower front of the unit.

[0057] Similar to the first embodiment, it also includes two sets of linear cylinders 672 to drive two air guide plates 671. The two air guide plates 671 are located on opposite sides of the air outlet 670 and together block the air outlet 670. Unlike the first embodiment, one set of linear cylinders 672 and the fixing component are horizontally arranged.

[0058] In the above embodiments, the center lines (first center lines) around which the two air guide vanes of the indoor unit swing are parallel to each other. In other embodiments, when it is necessary to use two air guide vanes to guide air in different directions, for example, one air guide vane is used for pitch angle swing to guide air up and down, and the other air guide vane is used for horizontal angle swing to guide air left and right, in this arrangement, the center lines around which the two air guide vanes swing are not on the same plane. Note that the air outlet referred to in this invention does not simply refer to the opening of the indoor unit casing, but rather to an air outlet structure with a certain distance between the fan blades and the opening of the indoor unit. In embodiments where the center lines around which the two air guide vanes swing are not on the same plane, the two air guide vanes are arranged in a back-to-back manner, with one air guide vane closer to the fan blades and farther from the opening of the indoor unit casing than the other air guide vane.

[0059] In other embodiments, the cylinder body of the linear cylinder is movably installed inside the indoor unit. For example, the cylinder body can be oscillating. In this configuration, the linear cylinder, the air guide plate, and the fixed component are rotatably connected to each other to form a linkage mechanism.

[0060] In other embodiments, the pneumatic device is a rotary cylinder, and the rotation output end of the rotary cylinder directly drives the air guide plate to swing.

[0061] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
