Description

Technical Field

[0001] The present invention relates to the technical field of air conditioner testing, and in particular to an air conditioner performance testing tool and an air conditioner performance testing system. Background Art

[0002] At present, some air conditioners need to be subjected to performance tests before they leave the factory and during the development process. Currently, the air conditioners are usually directly assembled on tooling structures such as test benches, and then the test system (such as enthalpy difference laboratory) is directly connected to the air conditioners to realize the test function.

[0003] In the prior art, for air conditioners whose actual final installation position is at the top of the room and whose air inlets and outlets are in a vertically downward direction (such as ceiling units and some duct units), it is usually necessary to install the air conditioner to be tested on the top of a tooling and assemble it downward. During the assembly process, due to the blind spot on the lower side of the air conditioner to be tested, it is necessary to continuously calibrate under the tooling during assembly. At the same time, it is also necessary to calibrate under the tooling during the test process to prevent the air inlet and outlet from being blocked, which greatly consumes manpower and affects the work efficiency of testers and R&D personnel. Summary of the invention

[0004] The problem solved by the present invention is how to accurately assemble the air conditioner to be tested, avoid blind spots in the field of vision, and enable the tester to observe the lower side of the air conditioner to be tested during the assembly process, thereby improving the assembly efficiency.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] An air conditioner performance test tool comprises an installation test bench, a first reflector and a second reflector, wherein an assembly installation position for assembling an air conditioner to be tested is arranged on the top of the installation test bench, an observation port extending through the top of the installation test bench is opened at the bottom of the installation test bench, and the assembly installation position is arranged around the observation port so that the projection of the air conditioner to be tested on the installation test bench at least partially falls into the observation port; the first reflector is arranged below the observation port, the second reflector is used to be arranged on a test surface spaced from the installation test bench, and the first reflector is inclined relative to a horizontal plane, and is used to receive a first light in the observation port and reflect a second light toward the second reflector, and the second reflector is used to receive the second light and reflect a third light toward the top of the installation test bench, so that an observer located on the installation test bench can observe the air conditioner to be tested through the observation port.

[0007] The present invention provides an air conditioner performance test tool, which sets a first reflector below the installation test bench and sets a second reflector on the test surface separated from the installation test bench, and the first reflector is set at an angle. Through the double reflection effect of the first reflector and the second reflector, the assembler on the installation test bench can observe the bottom side of the air conditioner to be tested through the observation port, eliminating the visual blind spot of the bottom side of the air conditioner to be tested during the assembly process, so that the bottom side of the air conditioner to be tested can be conveniently and accurately aligned with the assembly installation position, so that the air conditioner to be tested can be quickly assembled in place. Compared with the prior art, the air conditioner performance test tool provided by the present invention can accurately assemble the air conditioner to be tested, avoid the visual blind spot, and enable the tester to observe the bottom side of the air conditioner to be tested during the assembly process, avoiding repeated calibration and improving assembly efficiency.

[0008] Further, the angle α between the first reflector and the horizontal plane satisfies the following relationship:

[0009]

[0010] tanβ=H T / L T ;

[0011] tanγ=H B / L B ;

[0012] The line connecting the observed point T on the air conditioner to be tested and the reflection point A on the first reflector is AT, and the line connecting the reflection point A on the first reflector and the reflection point B on the second reflector is AB, where β is the angle between AT and the horizontal plane, γ is the angle between AB and the horizontal plane, and H B is the height of B relative to the horizontal plane where A is located, L B is the projection length of AB on the horizontal plane, H T is the height of T relative to the horizontal plane where A is located, L T is the projection length of AT on the horizontal plane.

[0013] Furthermore, a height HB of the reflection point B on the second reflector relative to the horizontal plane where the reflection point A on the first reflector is located is greater than half a height of the top of the installation test bench relative to the horizontal plane where the reflection point A on the first reflector is located.

[0014] The air conditioner performance testing tool provided by the present invention sets the second reflector at a height greater than half of the top of the installation test bench, so that assemblers can more easily observe the situation in the observation port through the second reflector, further facilitating the assembly of the air conditioner.

[0015] Furthermore, a midpoint of a side of the installation test bench close to the second reflector, a geometric center point of the second reflector, and a geometric center point of the first reflector are coplanar.

[0016] The air conditioner performance testing tool provided by the present invention arranges the first reflector and the second reflector at the position of the plane where the midpoint of the installation test bench is located, so that the first reflector and the second reflector can reflect most of the light in the observation port near the middle of the installation test bench, thereby improving the observable range and further facilitating the assembly of the air conditioner.

[0017] Furthermore, the second reflector is in a disk shape, and a reflective area of ​​the second reflector is equal to a reflective area of ​​the first reflector.

[0018] The air conditioner performance testing tool provided by the present invention can provide a wider field of view within the same area through the disc-shaped second reflector, thereby eliminating the need for an overly large second reflector, saving material for the second reflector and reducing costs.

[0019] Furthermore, a sampling bracket is arranged below the observation port, the top end of the sampling bracket extends into the observation port, and the first reflector is arranged at the bottom end of the sampling bracket.

[0020] The air conditioner performance testing tool provided by the present invention provides support for the first reflector by arranging the first reflector at the bottom end of the sampling bracket, which can avoid the need to additionally arrange a mounting bracket for the first reflector and also ensure the stability of the first reflector.

[0021] Furthermore, a light source is provided at the top of the sampling bracket, and the light source is used to illuminate the air conditioner to be tested that falls into the observation port.

[0022] The air conditioner performance testing tool provided by the present invention can further illuminate the empty strip device to be tested in the observation port by arranging a light source at the top of the sampling bracket, increase the light intensity of the reflected light, and enable the observer to observe a clearer and brighter image, further facilitating the assembly of the air conditioner.

[0023] Furthermore, the sampling bracket includes a support rod and a chassis, the chassis is arranged at the bottom of the support rod for supporting the support rod, and the side of the chassis close to the second reflector has a stepped slope, and the surface of the stepped slope is coated with a reflective layer for forming the first reflector.

[0024] An air conditioner performance test system includes an air conditioner to be tested and an air conditioner performance test tool, the air conditioner performance test tool includes a mounting test bench, a first reflector and a second reflector, the top of the mounting test bench is provided with an assembly installation position, the bottom of the mounting test bench is provided with an observation port extending through the top, and the projection of the air conditioner to be tested on the mounting test bench at least partially falls into the observation port; the first reflector is arranged below the observation port, the second reflector is used to be arranged on a test surface spaced from the mounting test bench, and the assembly installation position is arranged around the observation port, and is used to receive a first light in the observation port and reflect a second light toward the second reflector, and the second reflector is used to receive the second light and reflect a third light toward the top of the mounting test bench, so that an observer located on the mounting test bench can observe the air conditioner to be tested through the observation port. The air conditioner to be tested is mounted on the assembly installation position, and the air conditioner to be tested at least partially falls into the observation port.

[0026] Furthermore, the shape of the observation port matches the shape of the air inlet of the air conditioner to be tested, so that the air inlet overlaps with the observation port.

[0027] The air-conditioning performance testing system provided by the present invention has an air inlet and an observation port that overlap, thereby preventing the air inlet from being blocked by the installation test bench. At the same time, the alignment of the edge contour of the air inlet and the edge contour of the observation port also provides an assembly reference, thereby enabling more accurate installation of the air conditioner to be tested.

DETAILED DESCRIPTION

[0034] As disclosed in the background technology, for the performance test of ceiling air conditioners, some duct air conditioners, etc., the existing test tooling has a blind spot during installation, which makes it difficult for the assembler to assemble the air conditioner to be tested in place at one time. Since the test tooling needs to test air conditioners of different models and sizes, it is difficult to know the precise assembly position after multiple assembly and set the relevant fixed structures such as the installation slot of fixed size on the installation table of the tooling. Therefore, the existing solution usually requires the assembler to constantly calibrate back and forth above and below the installation table until the air conditioner is assembled in place, which is very time-consuming and laborious. At the same time, during the test, if the assembly is not in place, the tester needs to connect the power cord above the wind receiving chamber, place the air conditioner, and then drill to the position below the installation table for secondary adjustment. The adjustment process is repeated, and the air duct needs to be inspected to prevent the air duct from being blocked during installation. This undoubtedly greatly increases the workload of the testers and R&D personnel and affects the work efficiency.

[0035] The present invention solves the problem of blind spots in the assembly process through the principle of optical reflection, so that assemblers and testers can achieve accurate installation of the air conditioner without having to calibrate up and down. The assembly process is efficient and convenient, which reduces workload and improves work efficiency.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0037] First embodiment

[0038] See also Figure 1 and Figure 2 The present embodiment provides an air conditioner performance testing tool 100, which is used to assemble the air conditioner 200 to be tested and is connected to a testing device. When assembling the air conditioner 200 to be tested, the blind spot of the field of vision during assembly can be eliminated, so that the tester can observe the lower side of the air conditioner 200 to be tested during the assembly process, thereby avoiding repeated calibration and improving assembly efficiency.

[0039] The air conditioner performance test tool 100 provided in this embodiment includes a test bench 110, a first reflector 130 and a second reflector 150. The top of the test bench 110 is provided with an assembly installation position 111 for assembling the air conditioner 200 to be tested. The bottom of the test bench 110 is provided with an observation port 170 extending through the top, and the assembly installation position 111 is arranged around the observation port 170 so that the projection of the air conditioner 200 to be tested on the test bench 110 at least partially falls into the observation port 170. The first reflector 130 The second reflector 150 is arranged below the observation port 170 and is used to be arranged on a test surface 151 spaced apart from the installation test bench 110, and the first reflector 130 is arranged to be inclined relative to the horizontal plane, and is used to receive the first light in the observation port 170 and reflect the second light toward the second reflector 150, and the second reflector 150 is used to receive the second light and reflect the third light toward the top of the installation test bench 110, so that an observer located on the installation test bench 110 can observe the air conditioner 200 to be tested through the observation port 170.

[0040] It is worth noting that in this embodiment, the test surface 151 is a vertical plane, specifically, the wall where the power supply terminal is located. In actual installation, the test bench 110 is installed at intervals from the wall, and the second reflector 150 is attached to the wall, so that the second reflector 150 is kept in a vertical direction. In this embodiment, the first light refers to all the light from the point to be observed to the first reflector 130, the second light refers to all the light from the point to be observed reflected by the first reflector 130, and the third light refers to all the light from the point to be observed reflected by the second reflector 150, that is, the second light is obtained by reflecting the first light, and the third light is obtained by reflecting the second light.

[0041] In this embodiment, the air conditioner 200 to be tested is a ceiling air conditioner, whose air inlet and air outlet are both at the bottom, and the air inlet corresponds to the observation port 170, so that air can enter through the observation port 170, and the observation port 170 is located at the center of the installation test bench 110, and its shape matches the air inlet. Of course, the air conditioner 200 to be tested here can also be other air conditioners with air outlets facing downward, such as duct air conditioners, etc., which are not specifically limited here.

[0042] In this embodiment, the observation port 170 is used as an air inlet channel to supply air to the air inlet of the ceiling machine. In addition, the top surface of the installation test bench 110 also has a plurality of air inlet openings. After the ceiling machine is assembled in place, the plurality of air inlet openings respectively correspond to the plurality of air outlets of the ceiling machine. The plurality of air inlet openings are used to direct the air outlet of the ceiling machine to the test device, such as the enthalpy difference laboratory, so as to achieve the test of the air outlet performance. A separating ring plate is provided between the plurality of air inlet openings and the observation port 170. After the ceiling machine is assembled in place, the ring plate will not block the air inlet or the air outlet, so that the air inlet and outlet of the ceiling machine will not be blocked, which is more conducive to obtaining accurate test data.

[0043] In this embodiment, support frames 113 are arranged around the bottom of the installation test bench 110, and an air inlet cavity is formed in the middle. A first reflector 130 is arranged at the bottom of the air inlet cavity, and the support frame 113 does not block the reflected light path of the first reflector 130, so that the first reflector 130 can reflect light onto the second reflector 150.

[0044] The present embodiment provides a ceiling machine performance test tool, which arranges a first reflector 130 below an installation test bench 110, and arranges a second reflector 150 on a test surface 151 spaced apart from the installation test bench 110, and the first reflector 130 is arranged at an angle. Through the double reflection effects of the first reflector 130 and the second reflector 150, the assembler on the installation test bench 110 can observe the bottom side of the ceiling machine to be tested through the observation port 170, thereby eliminating the blind spot of the bottom side of the ceiling machine to be tested during the assembly process, so that the bottom side of the ceiling machine to be tested can be conveniently and accurately aligned with the assembly installation position 111, so that the ceiling machine to be tested can be quickly assembled into place.

[0045] It is worth noting that in the present embodiment, the field of view conversion is achieved through secondary reflection by the first reflector 130 and the second reflector 150. In other preferred embodiments, a third reflector or even a fourth reflector may be provided according to the actual installation environment to achieve field of view conversion through multiple reflections. The specific structure and installation position relationship will not be introduced in detail again.

[0046] It should be noted that the top surface of the installation test bench 110 is planar. The assembly installation position 111 in this embodiment refers to the planar area around the observation port 170, which does not have a limiting function. When assembling the ceiling machine to be tested, its position is mainly fixed by the deadweight of the ceiling machine, and the position of the ceiling machine can be moved under the action of external force, so that the ceiling machine can be assembled to a predetermined position. After being assembled in place, the position of the ceiling machine can be fixed by an adhesive structure to prevent the ceiling machine from shifting during the test, for example, by bonding the ceiling machine to the installation test bench 110 around with tape, or by other detachable tooling to fix the ceiling machine.

[0047] It should also be noted that, in this embodiment, “falling into the observation port 170 ” refers to the projection on the horizontal plane overlapping with the observation port 170 , so that the relevant structure can be observed through the observation port 170 .

[0048] See also Figure 3 In this embodiment, the angle α between the first reflector 130 and the horizontal plane satisfies the following relationship:

[0049]

[0050] tanβ=H T / L T ;

[0051] tanγ=H B / L B ;

[0052] The line connecting the observed point T on the air conditioner 200 to be tested and the reflection point A on the first reflector 130 is AT, and the line connecting the reflection point A on the first reflector 130 and the reflection point B on the second reflector 150 is AB, where β is the angle between AT and the horizontal plane, γ is the angle between AB and the horizontal plane, and H B is the height of B relative to the horizontal plane where A is located, L B is the projection length of AB on the horizontal plane, H T is the height of T relative to the horizontal plane where A is located, L T is the projection length of AT on the horizontal plane.

[0053] Specifically, in this embodiment, the angle α between the first reflector 130 and the horizontal plane can be calculated by the light reflection theory, where the height H of the reflection point B on the second reflector 150 is B and the horizontal length L compared to point A B All of them are determined according to the actual laboratory conditions and obtained through measurement. At the same time, the height H of the observation point T T and horizontal distance L T It can also be known through measurement that, when the positions of point T and point B are known, it is not difficult to obtain the specific angle value of the angle α between the first reflector 130 and the horizontal plane through the above formula.

[0054] It should be noted that the point to be observed on the air conditioner 200 to be tested here refers to a point on the boundary line between the bottom side of the ceiling unit to be tested and the edge contour of the observation port 170. When the first reflector 130 and the second reflector 150 have sufficient areas, the assembler can observe the entire top structure of the air conditioner 200 to be tested that falls into the observation port 170 through the first reflector 130 and the second reflector 150. In this embodiment, it is preferred that the first reflector 130 can reflect the edge contour boundary line close to the second reflector 150 onto the second reflector 150 and be observed by the assembler.

[0055] In this embodiment, the angle α between the first reflector 130 and the horizontal plane is 45°, so that the blind spot of the visual field can be eliminated. The specific value of the angle α between the first reflector 130 and the horizontal plane is not specifically limited here.

[0056] In this embodiment, the height H of the reflection point B on the second reflector 150 relative to the horizontal plane where the reflection point A on the first reflector 130 is located is B The height of the second reflector 150 is greater than half of the height of the top of the test bench 110 relative to the horizontal plane where the reflection point A on the first reflector 130 is located. By arranging the second reflector 150 at a height greater than half of the top of the test bench 110, the assembler can more easily observe the situation in the observation port 170 through the second reflector 150, which further facilitates the assembly of the air conditioner.

[0057] In this embodiment, the midpoint of the side of the installation test bench 110 close to the second reflector 150, the geometric center point of the second reflector 150, and the geometric center point of the first reflector 130 are coplanar. By arranging the first reflector 130 and the second reflector 150 at the position of the plane where the midpoint of the installation test bench 110 is located, the first reflector 130 and the second reflector 150 can reflect most of the light in the observation port 170 close to the middle of the installation test bench 110, thereby improving the observable range and further facilitating the assembly of the air conditioner.

[0058] In this embodiment, the second reflector 150 is in a disc shape, and the reflection area of ​​the second reflector 150 is equal to the reflection area of ​​the first reflector 130. The disc-shaped second reflector 150 can provide a wider field of view within the same area, thereby eliminating the need for an overly large second reflector 150, saving material for the second reflector 150 and reducing costs.

[0059] It should be noted that the larger the area of ​​the second reflector 150 is, the more comprehensive the observation field of view is. For economic considerations, the area of ​​the second reflector 150 in this embodiment is the same as that of the first reflector 130, which can save materials and reduce costs while eliminating blind spots in the field of view.

[0060] See also Figure 4 A sampling bracket 190 is disposed below the observation port 170, the top of the sampling bracket 190 extends into the observation port 170, and the first reflector 130 is disposed at the bottom of the sampling bracket 190. Specifically, a sampling module is also disposed at the top of the sampling bracket 190, and the sampling function can be realized by extending the top of the sampling bracket 190 into the observation port. By disposing the first reflector 130 at the bottom of the sampling bracket 190, support is provided for the first reflector 130, and an additional mounting bracket for the first reflector 130 can be avoided, while also ensuring the stability of the first reflector 130.

[0061] In this embodiment, a light source 195 is further provided at the top of the sampling bracket 190, and the light source 195 is used to illuminate the air conditioner 200 to be tested that falls into the observation port 170. By providing the light source 195 at the top of the sampling bracket 190, the air conditioner to be tested in the observation port can be further illuminated, the light intensity of the reflected light can be increased, and the observer can observe a clearer and brighter image, which further facilitates the assembly of the air conditioner.

[0062] The sampling bracket 190 includes a support rod 191 and a chassis 193. The chassis 193 is arranged at the bottom of the support rod 191 to support the support rod 191, and the side of the chassis 193 close to the second reflector 150 has a stepped slope, and the surface of the stepped slope is coated with a reflective layer for forming the first reflector 130.

[0063] In this embodiment, the chassis 193 is in the shape of a trapezoidal boss, and a step slope is provided on the side close to the wall, and the reflective layer is directly provided on the step slope by plating a reflective material. Specifically, the reflective layer can be formed by plating silver or aluminum on the step slope and covering it with a layer of transparent glass.

[0064] In summary, the air conditioner performance test tool 100 provided in this embodiment, when actually assembling the ceiling machine, first place the ceiling machine on the assembly installation position 111. Due to the double reflection effect of the first reflector 130 and the second reflector 150, the test assembly personnel can observe the structure of the bottom of the ceiling machine on the test installation table, so as to facilitate the adjustment of the position of the ceiling machine and avoid blind spots in the field of vision. This embodiment uses basic optical principles to achieve the conversion of the field of vision, so that after the test personnel have connected the wires on the experimental table, they can adjust the position of the ceiling machine in one go according to the field of vision in the second plane mirror, which reduces the work of the experimental test personnel and reduces the error rate of unreasonable placement of the ceiling machine.

[0065] Second embodiment

[0066] An air conditioning performance testing system includes an enthalpy difference test chamber, an air conditioner 200 to be tested, and an air conditioner performance testing tool 100, wherein the basic structure and principle of the air conditioner performance testing tool 100 and the technical effect produced are the same as those of the first embodiment. For the sake of brief description, for parts not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.

[0067] The air conditioner performance test tool 100 includes a test bench 110, a first reflector 130 and a second reflector 150. The top of the test bench 110 is provided with an assembly installation position 111. The bottom of the test bench 110 is provided with an observation port 170 extending through the top, and the projection of the air conditioner 200 to be tested on the test bench 110 at least partially falls into the observation port 170. The first reflector 130 is provided below the observation port 170, and the second reflector 150 is used to be provided on a test surface 151 spaced apart from the test bench 110. The test bench 110 is provided with an assembly installation position 111 arranged around the observation port 170, for receiving the first light in the observation port 170 and reflecting the second light toward the second reflector 150, and the second reflector 150 is used to receive the second light and reflect the third light toward the top of the test bench 110, so that an observer located on the test bench 110 can observe the air conditioner 200 to be tested through the observation port 170. The air conditioner 200 to be tested is assembled on the assembly installation position 111, and the air conditioner 200 to be tested at least partially falls into the observation port 170. The enthalpy difference test chamber is connected to the test bench 110, and is used to perform performance tests on the air conditioner 200 to be tested.

[0068] The air conditioner performance testing system provided in this embodiment solves the problem of blind spots in the field of vision through the combination of the first reflector 130 and the second reflector 150 , thereby improving assembly efficiency and further improving testing efficiency.

[0069] In this embodiment, the air conditioner 200 to be tested is a ceiling unit, whose air inlet and air outlet are both at the bottom, and the air inlet corresponds to the observation port 170, so that air can enter through the observation port 170, and the observation port 170 is located at the center of the installation test bench 110, and the shape of the observation port 170 matches the shape of the air inlet of the air conditioner 200 to be tested, so that the air inlet and the observation port 170 overlap.

[0070] In this embodiment, the observation port 170 is used as an air inlet channel to supply air to the air inlet of the ceiling machine. In addition, the top surface of the installation test bench 110 also has multiple air inlet openings. After the ceiling machine is assembled in place, the multiple air inlet openings correspond to the multiple air outlets of the ceiling machine respectively. The multiple air inlet openings are used to guide the air outlet of the ceiling machine to the enthalpy difference laboratory, thereby realizing the test of the air outlet performance. A separating ring plate is provided between the multiple air inlet openings and the observation port 170. After the ceiling machine is assembled in place, the ring plate will not block the air inlet or the air outlet, so that the air inlet and outlet of the ceiling machine will not be blocked, which is more conducive to obtaining accurate test data.

[0071] In the air conditioning performance testing system provided by the present invention, the air inlet overlaps with the observation port 170, which can avoid the installation test bench 110 from blocking the air inlet. At the same time, the alignment of the edge contour of the air inlet and the edge contour of the observation port 170 also provides an assembly reference, which can more accurately install the air conditioner 200 to be tested.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
