Description

Technical Field

[0001] This utility model relates to the field of air conditioning performance testing technology, and in particular to a quick air duct guiding device and an air supply performance testing device for air conditioners. Background Technology

[0002] During the research and development or maintenance phase of air conditioners, testing the air delivery quality of the indoor unit is crucial. These tests include evaluating key indicators such as air volume, air temperature, and air humidity to ensure that the air conditioner's cooling and heating effects meet expected standards, thereby comprehensively assessing its performance. To conduct these tests, a testing device with an air inlet is typically used, connected to the air outlet of the indoor unit via a duct structure. This design allows the air exhausted from the indoor unit to smoothly enter the testing device, facilitating accurate testing of the air conditioner's air delivery quality. Currently, constructing the duct structure usually involves cutting and assembling several air guide plates into a suitable duct for performance testing. In the process of developing the prior art, the inventors discovered:

[0003] If the duct structure remains consistent, it will be difficult to accommodate various air outlets of different shapes and sizes. When performing performance tests on multiple air conditioners with different air outlet shapes and sizes, ducts matching each outlet must be prepared, which undoubtedly increases the cost of performance testing and leads to significant resource waste. Furthermore, errors in dimensional cutting are prone to occur, which not only severely delays the testing schedule but also reduces testing efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a quick air guiding device for air ducts and an air supply performance testing device for air conditioners, thereby overcoming the shortcomings of the prior art.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] The first aspect of this utility model provides a quick air guiding device for a duct, including a duct shell and a duct frame. The duct shell wraps around the duct frame to form a duct with an air outlet and an air inlet. The duct interface portion of the duct frame near the air outlet and the air inlet is a telescopic structure that can expand and contract along its own circumference. The portion of the duct shell that wraps around the telescopic structure of the duct frame is flexible. The shape and area of ​​the air outlet and the air inlet can change with the expansion and contraction of the telescopic structure.

[0007] Furthermore, the air duct interface portion includes n support rods connected end to end, wherein at least one of the support rods is telescopic.

[0008] Furthermore, the support rod includes an outer tube and an inner tube, with the inner tube sleeved inside the outer tube and slidably connected to the outer tube.

[0009] Furthermore, a self-locking mechanism is provided on the inner wall of the outer tube, and multiple grooves are provided axially spaced on the outer wall of the inner tube. The self-locking mechanism is partially rotated and locked into the grooves, so that the inner tube and the outer tube cannot slide relative to each other axially.

[0010] Furthermore, the support rod is provided with a scale for measuring the extension length.

[0011] Furthermore, a support structure is provided on the air duct frame, which supports the air duct frame and extends and retracts synchronously with the telescopic structure.

[0012] In a more specific embodiment, the support structure includes multiple metal wires that are cross-hinged to form an elastic telescopic mesh, which expands and contracts synchronously with the airflow outlet and the airflow inlet duct interface. Preferably, the diameter of the metal wires is 2 mm.

[0013] In a more specific embodiment, the support structure includes multiple metal wires, each with an adjustment buckle for synchronously extending and retracting with the air duct interface portions of the airflow outlet and the airflow inlet.

[0014] The second aspect of this utility model provides an air conditioner air supply performance testing device, including an air conditioner, an air supply performance testing device, and a duct quick air guide device, wherein the air conditioner supplies air to the air supply performance testing device through the duct quick air guide device.

[0015] Compared with the prior art, the advantages of this utility model include at least the following:

[0016] First, the present invention provides a duct quick-access air guiding device. The interface portion of the duct frame, near the air outlet and air inlet, is designed to be circumferentially expandable. The duct shell covers the expandable portion of the frame and is made of flexible material. Therefore, the shape and area of ​​the air outlet and air inlet can be adjusted accordingly to the changes in the expandable structure, thereby adapting to air outlets of different shapes and sizes, simplifying the duct manufacturing process, shortening production time, and effectively improving work efficiency.

[0017] Secondly, the present invention provides a quick air guiding device for air ducts, wherein metal wires are wound on the air duct frame for synchronous expansion and contraction with the telescopic structure, which can make the length and width of the airflow channel consistent, and at the same time play a role in supporting the air duct shell, preventing the air duct shell from collapsing, generating wind resistance, and affecting test performance.

[0018] Third, the present invention provides a quick-access air guiding device for air ducts, wherein the air duct interface is composed of n support rods connected end to end, and both its air inlet and outlet are designed as retractable rectangular structures. This design is more suitable for air supply systems, is easy to install, and does not affect the wind speed, thereby improving the accuracy of testing. Attached Figure Description

[0025] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0026] Please refer to Figure 1 This embodiment provides a quick air guiding device for air ducts, including an air duct shell and an air duct frame. The air duct shell is wrapped around the air duct frame to form an air duct with an airflow outlet and an airflow inlet.

[0027] Along the AB direction, the air duct is used for gas flow. The outer shell of the air duct facilitates the installation of heat insulation panels thereon.

[0028] The duct frame near the airflow outlet and the airflow inlet is a telescopic structure that can expand and contract along its own circumference. The part of the duct shell that encloses the telescopic structure of the duct frame is flexible. The shape and area of ​​the airflow outlet and the airflow inlet can change with the expansion and contraction of the telescopic structure according to the size of the air outlet to be measured.

[0029] Specifically, the telescopic structures of the airflow outlet and the airflow inlet are fixed to the duct interface and can be made relatively narrow so as not to affect the airflow output. Their thickness can also be made relatively thin so as not to affect the overall aesthetics.

[0030] In a preferred embodiment, the duct interface includes n end-to-end support rods, at least one of which is telescopic. The length of the support rods ranges from 0.5 to 2 meters. Specifically, the telescopic structure of the airflow inlet includes a first support rod 11, a second support rod 12, a third support rod 13, and a fourth support rod 14, and the telescopic structure of the airflow outlet includes a fifth support rod 15, a sixth support rod 16, a seventh support rod, and an eighth support rod. This telescopic rectangular structure for both the airflow inlet and outlet is more suitable for air distribution structures, facilitating installation and preventing obstruction of the control surface, thus not affecting wind speed and improving testing accuracy.

[0031] Preferably, the support rod includes an outer tube and an inner tube, the inner tube being sleeved inside the outer tube and slidably connected to the outer tube. For example... Figure 2 The dotted line represents the overlapping portion of the inner and outer tubes, which is the telescopic concealment distance of the telescopic rod. The shape and area of ​​the airflow outlet and inlet can be changed using the telescopic support rod, adapting to various air outlets of different shapes and sizes. This is simple, quick, reduces ductwork fabrication time, and improves work efficiency.

[0032] In a preferred embodiment, a self-locking mechanism is provided on the inner wall of the first support rod 11, the second support rod 12, the third support rod 13, the fourth support rod 14, the fifth support rod 15, the sixth support rod 16, the seventh support rod, and the eighth support rod. Multiple grooves are spaced axially on the outer wall of the inner tube of each of the first support rod 11, the second support rod 12, the third support rod 13, the fourth support rod 14, the fifth support rod 15, the sixth support rod 16, the seventh support rod, and the eighth support rod. The self-locking mechanism partially rotates and engages with these grooves, preventing the inner and outer tubes from sliding relative to each other axially. This self-locking mechanism can be a push-button type. For example, please refer to... Figure 3 It can be pressed and fastened (19).

[0033] In a preferred embodiment, the first support rod 11, the second support rod 12, the third support rod 13, the fourth support rod 14, the fifth support rod 15, the sixth support rod 16, the seventh support rod, and the eighth support rod are provided with scales for measuring the telescopic length.

[0034] In a preferred embodiment, a support structure is provided on the duct frame. This support structure supports the duct frame and extends / retracts synchronously with the telescopic structure. Preferably, the support structure comprises multiple metal wires, which are interlocked to form an elastic telescopic net that extends / retracts synchronously with the duct interface portions at the airflow outlet and airflow inlet. Stainless steel wires can be used here. The stainless steel wires are interlocked to form an elastic telescopic net that surrounds the airflow channel, with the surrounding direction of the stainless steel wires perpendicular to the gas flow direction.

[0035] For details, please refer to Figure 4 Stainless steel wire is wound around the first panel 20, the second panel 21, the third panel 22, and the fourth panel 23, and the winding direction of the stainless steel wire is perpendicular to the airflow direction. Preferably, the diameter of the wire is 2 mm.

[0036] In a preferred embodiment, the duct housing is a rubber duct housing.

[0037] This embodiment also provides an air conditioner air supply performance testing device, including an air conditioner, an air supply performance testing device, and a duct quick air guide device, wherein the air conditioner supplies air to the air supply performance testing device through the duct quick air guide device.
