Description

Technical Field

[0001] The present invention relates to the field of air-conditioning measuring devices, in particular to an air-conditioning refrigeration effect detection device. Background Art

[0002] Air conditioners typically have a sweep function. When the guide vanes at the air outlet rotate, a sweep zone is formed diagonally below the outlet. The wind speed at the front and rear extremes of the sweep zone, as well as the temperature drop within the sweep zone, are key factors in determining the air conditioner's cooling performance. Therefore, after air conditioners are manufactured, the wind speed at the extremes of the sweep zone and the temperature drop within the sweep zone need to be measured to evaluate the cooling performance.

[0003] In the existing technology, inspection personnel generally hold a thermometer and anemometer in their hands to measure the temperature and wind speed within the air sweeping range of the air conditioner. This requires the inspection personnel to move back and forth, which is time-consuming and labor-intensive, and has low inspection efficiency. Summary of the Invention

[0004] The present invention provides an air conditioner refrigeration effect detection device to solve the problem of low efficiency in the prior art air conditioner air outlet wind speed and temperature detection.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: An air conditioning cooling effect detection device comprises a support frame, a connecting member body (1) is provided on the support frame, a temperature sensor (9) is provided on the connecting member body (1), two symmetrical sides of the connecting member body (1) are respectively provided with a slide groove (3), the slide grooves (3) on both sides are parallel to and symmetrical to each other, and a slider (4) is slidably installed in the slide groove on each side; Mounting plates (7) are respectively provided on the two symmetrical sides of the connector body (1), and each mounting plate (7) is provided with a plurality of through holes, and an impeller (8) is rotatably mounted in each through hole through an impeller shaft, and each impeller shaft is equipped with a speed sensor. The mounting plate (7) on each side is connected to the slider (4) on the corresponding side of the connector body (1) through a scissor-type linkage mechanism. When the slider (4) slides in the corresponding slide groove (3), the scissor-type linkage mechanism causes the mounting plate (7) on the corresponding side to move toward or away from the connector body (1).

[0006] Furthermore, the support frame is a height-adjustable support frame.

[0007] Furthermore, the connector body (1) is provided with a driving mechanism at a position corresponding to each slide groove (3), and the driving mechanism drives the slider (4) in the corresponding slide groove (3) to slide.

[0008] Furthermore, the driving mechanism includes a screw rod (10) rotatably mounted in the slide groove (3), and the slider (4) is assembled on the screw rod (10) through a threaded through hole. The screw rod (10), the slider (4) and the slide groove (3) on each side constitute a screw rod and slider mechanism.

[0009] Furthermore, the screws in the screw slider mechanisms on both sides are connected through a pulley mechanism.

[0010] Furthermore, the scissor-type connecting rod mechanism includes a first straight arm (5), a second straight arm (13) and a connecting rod (14), wherein the first straight arm (5) and the second straight arm (13) are intersected and rotatably connected at the intersection, one end of the first straight arm (5) is rotatably connected to the slider (4) on the corresponding side, and the other end of the first straight arm (5) is rotatably connected to the mounting plate (7) on the corresponding side, one end of the second straight arm (13) is rotatably connected to the connecting member body (1), and the other end of the second straight arm (13) is rotatably connected to one end of the connecting rod (14), and the other end of the connecting rod (14) is rotatably connected to the mounting plate (7) on the corresponding side.

[0011] During testing, the device is placed within the sweeping range of the air conditioner being tested. The two mounting plates are then moved to their respective front and rear extremes. The impeller in each mounting plate rotates in response to the airflow from the corresponding position. A speed sensor measures the windage at that position, while a temperature sensor on the connector between the two mounting plates measures the temperature within the sweeping range.

[0012] Compared to existing technologies, the present invention eliminates the need for extensive human involvement during testing, saving time and effort and improving testing efficiency. Furthermore, the movable positions of the two mounting plates can be determined based on the airflow range of different air conditioners, making it suitable for a variety of air conditioners with different airflow ranges.

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, this embodiment discloses an air-conditioning cooling effect detection device, which includes a support frame, a connector body 1 , two sets of scissor-type linkage mechanisms, and two mounting plates 7 .

[0019] The support frame is a liftable support frame, which includes a lower support frame 16 and an upper movable frame 15. The lower support frame 16 and the upper movable frame 15 are both vertical. The side of the lower support frame 16 is connected to a number of legs, each of which is supported on the ground. The upper movable frame 15 is vertically slidably installed in the lower support frame 16, and the upper end of the upper movable frame 15 passes through the top of the lower support frame 16. The upper movable frame 15 is provided with a number of through holes along the radial direction, each of which is located at a different height position of the upper movable frame 15. The lower support frame 16 is provided with mounting through holes along the radial direction. When a through hole of the upper movable frame 15 is aligned with a mounting through hole of the lower support frame 16, the upper movable frame 15 and the lower support frame 16 are connected and fixed by bolts passing through the mounting through hole of the lower support frame 16 and the aligned through hole of the upper movable frame 15. Therefore, the support frame in this embodiment can be adjusted in height as needed.

[0020] The bottom center of the connector body 1 is fixed to the upper end of the upper movable frame 15 in the support frame. A temperature sensor 9 is installed at the right end of the connector body 1. The front and rear sides of the connector body 1 respectively have side seats 2. Each side seat 2 is respectively provided with a rectangular slide 3. Each slide 3 extends in the left and right horizontal directions respectively. The slides 3 on both sides are parallel and symmetrical to each other. A rectangular slider 4 is respectively slidably installed in each slide 3.

[0021] A screw rod 10 is rotatably connected between the left and right ends of each chute 3, with its axis running horizontally to the left and right. The slider 4 is screwed onto the screw rod 10 via a threaded through hole. The slider 4, screw rod 10, and chute 3 on each side form a screw-slider mechanism. The screw rod 10 forms a driving mechanism. When the screw rod 10 rotates, it drives the slider 4 on the same side to perform reciprocating linear motion within the chute 3.

[0022] The screw rods 10 on both sides are coaxially fixed with pulleys 11 at one end in the same direction. The pulleys 11 installed on the screw rods 10 on both sides are connected by a transmission belt 12. A motor is installed at the position corresponding to one of the pulleys 11 in the connector body 1. The motor output shaft is connected to the pulley at the corresponding position. The pulley 11 and the transmission belt 12 form a pulley mechanism. The motor drives the two screw rods 10 to rotate synchronously through the pulley mechanism.

[0023] One of the two mounting plates 7 is located in front of the side seat 2 on the front side of the connector body 1, and the other is located behind the side seat on the rear side of the connector body 1. Each mounting plate 7 is vertical, with one side facing the corresponding side seat 2, and a connecting seat 6 is fixed to the side facing the corresponding side seat 2 of each mounting plate 7.

[0024] Each mounting plate 7 is provided with a plurality of mounting through holes which pass through the plate body front to back. An impeller 8 is rotatably mounted in each mounting through hole through an impeller shaft which is axially horizontal front to back, and each impeller shaft is equipped with a speed sensor.

[0025] Of the two sets of scissor-type linkage mechanisms, one set of scissor-type linkage mechanisms is arranged between one mounting plate 7 and the side seat 2 on the corresponding side, and the other set of scissor-type linkage mechanisms is arranged between the other mounting plate and the side seat on the corresponding side.

[0026] Each scissor-type linkage mechanism includes a first straight arm 5, a second straight arm 13, and a connecting rod 14. In each scissor-type linkage mechanism, the first straight arm 5 and the second straight arm 13 intersect and are rotatably connected at the intersection via an axially vertical rotating shaft. One end of the first straight arm 5 is rotatably connected to the slider 4 on the corresponding side via the axially vertical rotating shaft, and the other end of the first straight arm 5 is rotatably connected to the connecting seat 6 on the mounting plate 7 on the corresponding side via the axially vertical rotating shaft. One end of the second straight arm 13 is rotatably connected to the side seat 2 on the corresponding side of the connector body 1 via the axially vertical rotating shaft, and the other end of the second straight arm 13 is rotatably connected to one end of the connecting rod 14 via the axially vertical rotating shaft. The other end of the connecting rod 14 is rotatably connected to the connecting seat 6 on the mounting plate 7 on the corresponding side.

[0027] Therefore, when the motor is working, the screw rods 10 on both sides rotate. When the screw rods 10 rotate, the corresponding sliders 4 slide in the slide grooves 3. When the sliders 4 move, the corresponding scissor-type linkage mechanism drives the mounting plates 7 on the corresponding sides to move closer to or away from the connector body 1.

[0028] When the present embodiment is tested, the device of the present embodiment is placed in the wind sweeping range according to the wind sweeping range of the air conditioner to be tested, and then the two mounting plates 7 are respectively moved to the front and rear limit positions of the wind sweeping range. The impeller in each mounting plate 7 rotates under the wind force of the air conditioner at the corresponding position, and the wind force at the corresponding position can be obtained through the speed sensor. At the same time, the temperature within the wind sweeping range can be collected by the temperature sensor 9 on the connector body 1, thereby realizing the detection of the cooling effect of the air conditioner.
