[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3 , the utility model provides a technical solution:

[0022] Embodiment 1:

[0023] See also Figure 1 A composite electrical appliance performance testing room includes a testing room body 1, an air outlet assembly 2 is arranged inside the testing room body 1, and the air outlet assembly 2 includes a servo motor 201 fixedly installed on the inner bottom wall of the testing room body 1, and the driving end of the servo motor 201 is connected to a connecting rod 202, and the outer wall of the connecting rod 202 is provided with two fixed disks 203, and the outer wall of the fixed disk 203 is fixedly installed with a plurality of fan blades 204, and the inner wall of the testing room body 1 is fixedly installed with a fixed plate 205, and the inner wall of the testing room body 1 is fixedly installed with a baffle 206, and the baffle 206 is provided with a plurality of apertures 207, one of the fixed disks 203 is located between the baffle 206 and the inner top wall of the testing room body 1, and the other fixed disk 203 is located between the fixed plate 205 and the inner bottom wall of the testing room body 1, and the fixed plate 205 is used to receive the product to be tested.

[0024] The servo motor 201 drives the connecting rod 202 to rotate. When the connecting rod 202 rotates, it drives the fixed plate 203 and the plurality of fan blades 204 to rotate. After the fan blades 204 above the baffle plate 206 rotate, the wind blown out will be transmitted to the top of the fixed plate 205 through the plurality of holes 207 opened in the baffle plate 206. The fixed plate 205 is used to support the product to be tested, thereby realizing longitudinal blowing;

[0025] When the multiple fan blades 204 under the fixed plate 205 rotate, the wind generated will blow upward from both sides of the fixed plate 205, and then blow toward the top of the fixed plate 205 from both sides of the inner wall of the detection chamber body 1, thereby realizing lateral blowing. Through lateral and longitudinal air outlets, it can adapt to products with different requirements for air outlet methods, thereby improving the test range of the detection chamber body 1.

[0026] See also Figure 1 A protective frame 3 is fixedly installed on the inner bottom wall of the detection chamber body 1, the servo motor 201 is located inside the protective frame 3, the outer wall of the connecting rod 202 is rotatably connected to the protective frame 3, and the connecting rod 202 is rotatably connected to the fixed plate 205 and the baffle 206.

[0027] The protection frame 3 protects the servo motor 201 and at the same time provides a certain support for the connecting rod 202 to prevent the weight of the connecting rod 202 from falling entirely on the servo motor 201. The connecting rod 202 is rotatably connected to the fixed plate 205 and the baffle 206, so that the connecting rod 202 can maintain the rotation effect and will not be affected by the fixed plate 205 and the baffle 206.

[0028] See also Figure 1Two fixing frames 5 are fixedly installed on the top of the fixing plate 205 . The fixing frames 5 are provided with ventilation holes 6 , which are connected to the ventilation slots 7 .

[0029] The wind from below enters between the fixing frame 5 and the detection chamber body 1 through the ventilation slots 7 , and then enters the top of the fixing plate 205 through the ventilation holes 6 opened in the fixing frame 5 .

[0030] See also Figure 1 A plurality of blocking plates 4 are arranged above the protective frame 3, one of the blocking plates 4 is fixedly mounted on the top of the protective frame 3, and the other two blocking plates 4 are fixedly mounted on the outer wall of the connecting rod 202. The lower fixed plate 203 is arranged on the top of one of the blocking plates 4 and below one of the blocking plates 4, and the upper fixed plate 203 is arranged below one of the blocking plates 4.

[0031] The blocking plate 4 limits the two fixed disks 203 to prevent the high-speed rotating fixed disks 203 from deflecting. The upper blocking plate 4 prevents the fixed disks 203 from sliding out of the connecting rod 202, and the two lower blocking plates 4 prevent friction between the fixed disks 203 and the protective frame 3 or the fixed plates 205.

[0032] See also Figure 1 A water tank 8 is fixedly installed on the outer wall of the detection chamber body 1, and a chamber 9 is opened in the water tank 8. A water pump 10 is fixedly installed on the inner bottom wall of the water tank 8. A water pipe 11 is connected between the water pump 10 and the detection chamber body 1. One end of the water pipe 11 away from the water pump 10 extends to the interior of the detection chamber body 1. The interior of the water tank 8 is used to hold water.

[0033] When testing products that require water, such as ice machines, water with constant temperature and pressure is required. The water tank 8 is used to store water. The gas in the chamber 9 is extracted by a vacuum pump to form a vacuum environment in the chamber 9. The vacuum environment can effectively prevent the occurrence of heat conduction and convection. In a vacuum state, the gas becomes very thin, and heat conduction and convection are almost impossible. Therefore, the heat can be well maintained in the container, so that the water in the water tank 8 can be kept warm. Then, one end of the water pipe 11 is connected to the water inlet of the ice maker, and then the water pump 10 is turned on to transport water to the water pipe 11 through the water pump 10.

[0034] Embodiment 2:

[0035] See also Figure 1-Figure 3 A plurality of triangular blocks 12 are fixedly mounted on the inner wall of the fixed disk 203, and two circular mounting plates 13 are fixedly mounted on the outer wall of the connecting rod 202. The circular mounting plates 13 are located inside the fixed disk 203, and a clamping block 14 is connected to the outer wall of the circular mounting plate 13. A spring 15 is connected between the clamping block 14 and the circular mounting plate 13. The triangular blocks 12 in the two fixed disks 203 are oriented in opposite directions to the clamping blocks 14.

[0036] The triangular blocks 12 and the clamping blocks 14 in the two fixed plates 203 are oriented in different directions. Therefore, when the connecting rod 202 drives the circular mounting plate 13 to rotate, the spring 15 in the upper fixed plate 203 is on the left side of the clamping block 14. Therefore, when longitudinal blowing is required, the circular mounting plate 13 is rotated counterclockwise, so that the end of the clamping block 14 away from the circular mounting plate 13 will abut against the outer wall of the triangular block 12.

[0037] Then, when the circular mounting plate 13 rotates counterclockwise, the clamping block 14 can drive the triangular block 12 and the fixed disk 203 to rotate, thereby rotating the upper fixed disk 203. The upper fixed disk 203 rotates to blow air to the product below the baffle 206. At the same time, since the lower spring 15 is located on the right side of the clamping block 14, when the circular mounting plate 13 rotates counterclockwise, the side of the clamping block 14 away from the spring 15 will abut against the triangular block 12, and then the clamping block 14 will squeeze the spring 15.

[0038] When the block 14 squeezes the spring 15 and comes close to the outer wall of the circular mounting plate 13, the triangular block 12 will pass over the block 14, so the block 14 will not drive the lower fixed disk 203 to rotate. If the lower fixed disk 203 does not rotate, horizontal ventilation cannot be achieved. When the connecting rod 202 and the circular mounting plate 13 rotate clockwise, the upper fixed disk 203 will not rotate, while the lower fixed disk 203 will rotate, thereby achieving horizontal blowing while longitudinal blowing cannot be achieved. In this way, the adjustment of longitudinal and transverse winds can be achieved. If you want to blow both longitudinally and transversely, one of the fixed disks 203 can be turned over so that the triangular blocks 12 and the block 14 in the two fixed disks 203 are in the same direction.

[0039] Working principle:

[0040] The servo motor 201 drives the connecting rod 202 to rotate. When the connecting rod 202 rotates, it drives the fixed plate 203 and the plurality of fan blades 204 to rotate. After the fan blades 204 above the baffle plate 206 rotate, the wind blown out will be transmitted to the top of the fixed plate 205 through the plurality of holes 207 opened in the baffle plate 206. The fixed plate 205 is used to support the product to be tested, thereby realizing longitudinal blowing;

[0041] When the multiple fan blades 204 under the fixed plate 205 rotate, the wind generated will blow upward from both sides of the fixed plate 205, and then blow toward the top of the fixed plate 205 from both sides of the inner wall of the detection chamber body 1, thereby realizing lateral blowing. Through lateral and longitudinal air outlets, it can adapt to products with different requirements for air outlet methods, thereby improving the test range of the detection chamber body 1.

[0042] The triangular blocks 12 and the clamping blocks 14 in the two fixed plates 203 are oriented in different directions. Therefore, when the connecting rod 202 drives the circular mounting plate 13 to rotate, the spring 15 in the upper fixed plate 203 is on the left side of the clamping block 14. Therefore, when longitudinal blowing is required, the circular mounting plate 13 is rotated counterclockwise, so that the end of the clamping block 14 away from the circular mounting plate 13 will abut against the outer wall of the triangular block 12.

[0043] Then, when the circular mounting plate 13 rotates counterclockwise, the clamping block 14 can drive the triangular block 12 and the fixed disk 203 to rotate, thereby rotating the upper fixed disk 203. The upper fixed disk 203 rotates to blow air to the product below the baffle 206. At the same time, since the lower spring 15 is located on the right side of the clamping block 14, when the circular mounting plate 13 rotates counterclockwise, the side of the clamping block 14 away from the spring 15 will abut against the triangular block 12, and then the clamping block 14 will squeeze the spring 15.

[0044] When the block 14 squeezes the spring 15 and comes close to the outer wall of the circular mounting plate 13, the triangular block 12 will pass over the block 14, so the block 14 will not drive the lower fixed disk 203 to rotate. If the lower fixed disk 203 does not rotate, horizontal ventilation cannot be achieved. When the connecting rod 202 and the circular mounting plate 13 rotate clockwise, the upper fixed disk 203 will not rotate, while the lower fixed disk 203 will rotate, thereby achieving horizontal blowing while longitudinal blowing cannot be achieved. In this way, the adjustment of longitudinal and transverse winds can be achieved. If you want to blow both longitudinally and transversely, one of the fixed disks 203 can be turned over so that the triangular blocks 12 and the block 14 in the two fixed disks 203 are in the same direction.
