[0029] As people's living standards improve, refrigerators have become a necessity in people's lives. Refrigerators use refrigeration to keep the interior of their storage chamber at a low temperature, thereby better preserving food. However, there are many types and brands of refrigerators, which makes consumers have many choices. How to win the favor of consumers and improve product competitiveness has become an issue that refrigerator manufacturers are paying more and more attention to.

[0030] In the related art, the evaporator of the refrigerator is an important part of the refrigerator's refrigeration system, and the performance of the evaporator affects the performance of the refrigerator's refrigeration system. Therefore, it is necessary to perform various performance tests on the evaporator. However, the current performance tests on the evaporator only place the evaporator in the test device. During the test, the comprehensive impact of various factors such as the air duct structure design and the fan operation on the evaporator's heat exchange capacity is not considered. It is impossible to accurately restore the working scene of the evaporator when exchanging heat inside the refrigerator. Therefore, there is a gap between the test data obtained and the actual situation. This leads to inaccurate performance test results of the evaporator.

[0031] Based on this, the present disclosure provides a detection device, which can simulate the working scene of the evaporator in the refrigerator and detect the heat exchange amount of the evaporator. The detection result of the evaporator by the detection device is more accurate.

[0032] like Figure 1 as well as Figure 2As shown, in some embodiments, the detection device 10 includes a first housing assembly 100, a second housing assembly 200, a third housing assembly 300, a first airflow generating assembly 400 and a detection assembly 500. The first housing assembly 100 is provided with a test cavity 110 and a plurality of connection ports 120 communicating with the test cavity 110. The test cavity 110 can simulate the environment in which the air duct of the refrigerator is located. The second housing assembly 200 includes a first air duct 210 and an air inlet 220 and an air outlet 230 communicating with the first air duct 210. The second housing assembly 200 is arranged in the test cavity 110. The evaporator 20 can be fixed in the first air duct 210. The third housing assembly 300 includes a second air duct 310 and a first interface 320 and a second interface 330 communicating with the second air duct 310, and the first interface 320 and the second interface 330 are arranged in the connection port 120 and are connected to the air inlet 220 and the air outlet 230 respectively, so that the second air duct 310 is connected to the first air duct 210. The first airflow generating assembly 400 is disposed in the second air duct 310. The first airflow generating assembly 400 can generate airflow in the first air duct 210 and the second air duct 310. The detection assembly 500 is disposed in the first air duct 210 and is used to detect the heat exchange amount of the evaporator 20.

[0033] In this way, when the detection device 10 is working, the evaporator 20 can be fixed in the first air duct 210 of the second housing assembly 200, and the detection assembly 500 is arranged in the first air duct 210 to detect the heat exchange capacity of the evaporator 20. The first air duct 210 can simulate the actual air duct of the refrigerator, so that the working scene of the evaporator 20 in the detection device 10 is closer to the working scene of the refrigerator, thereby improving the detection reliability of the heat exchange capacity of the evaporator 20. And the second housing assembly 200 is arranged in the test cavity 110 of the first housing assembly 100, so as to simulate the scene of the evaporator 20 and the air duct working in the refrigerator, so as to further improve the detection reliability of the heat exchange capacity of the evaporator 20. In the second air duct 310 of the third shell component 300, the first interface 320 and the second interface 330 are passed through the connecting port 120 and connected to the air inlet 220 and the air outlet 230 respectively, so that the first air duct 210 and the second air duct 310 are connected. The first air flow generating component 400 arranged in the second air duct 310 can simulate the air flow in the air duct of the refrigerator, thereby further improving the detection reliability of the heat exchange capacity of the evaporator 20.

[0034] It should be noted that the test cavity 110 can simulate the environment of the refrigerator air duct, such as temperature, humidity, etc. The second housing assembly 200 capable of simulating the refrigerator air duct is arranged in the test cavity 110, so that the detection device 10 can better simulate the actual working environment of the evaporator 20 in the refrigerator.

[0035] Researchers have found in practice that return air is generated in the air duct of the refrigerator. Figure 1As shown, in some embodiments, the detection device 10 further includes a second airflow generating component, which is disposed in the first air duct 210. Thus, by disposing the second airflow generating component in the first air duct 210, the scene of the evaporator 20 working in the refrigerator air duct is more closely simulated, and the supply and return air in the refrigerator air duct is simulated. Thus, the reliability of the detection of the heat exchange amount of the evaporator 20 is improved.

[0036] It should be noted that there may be many specific implementations of the first airflow generating component 400 and the second airflow generating component, including fans, blowers, and the like.

[0037] It should be noted that the first airflow generating component 400 and the second airflow generating component may be one or more and may be arranged according to implementation requirements, and are not further limited herein.

[0038] like Figure 1 as well as Figure 2 As shown, in some embodiments, the first interface 320 and the second interface 330 of the third housing assembly 300 are respectively connected to the air inlet 220 and the air outlet 230 of the second housing assembly 200 to form a closed loop. In this way, the design can better simulate the supply and return air in the refrigerator air duct and improve the reliability of the detection of the heat exchange of the evaporator 20.

[0039] like Figure 1 as well as Figure 2 As shown, in some embodiments, the air inlet 220 and the air outlet 230 are detachably connected to the first interface 320 and the second interface 330, respectively, so that the second housing assembly 200 can be detachably arranged in the test cavity 110. In this way, during the detection process of the detection device 10, the second housing assembly 200 is detachably arranged in the test cavity 110, so that the tester can replace the first air duct 210 where the evaporator 20 is located according to actual conditions, so that the detection device 10 can detect the heat exchange of the evaporator 20 in different air duct structures, and the heat exchange of the evaporator 20 when it is actually working in the refrigerator is more accurate.

[0040] Specifically, Figure 1 The second housing assembly 200 framed by the dotted line can be removed from the detection device.

[0041] In some embodiments, the second housing component 200 is an air passage used by a refrigerator. Thus, by directly using the air passage of the refrigerator as the second housing component 200 of the detection device 10, the evaporator 20 can better simulate the actual working scene in the refrigerator. Thus, the heat exchange detected by the detection device 10 is closer to the heat exchange of the evaporator 20 when working in the refrigerator, and the reliability of the detection result is improved.

[0042] In practice, researchers have found that the airflow in the air duct of most existing refrigerators flows along the direction of gravity. Therefore, in order to further improve the reliability of the detection results, in some embodiments, the air outlet 230 and the air inlet 220 are arranged in a spaced relationship along the direction of gravity. In this way, the direction of the airflow entering the first air duct 210 through the air inlet 220 flows along the direction of gravity, thereby more realistically simulating the scene of the evaporator 20 working in the refrigerator, and improving the reliability of the detection results.

[0043] In some embodiments, the detection device 10 further includes a refrigeration element (not shown), which is used to provide a refrigerant. The evaporator 20 is provided with a first inlet 21 and a first outlet 22. The refrigeration element is connected to the evaporator 20 through the first inlet 21 and the first outlet 22, so that the refrigerant flows in the evaporator 20. In this way, when the detection device 10 detects the evaporator 20, it only needs to connect the first inlet 21 and the first outlet 22 of the evaporator 20 to the refrigeration element to make the evaporator 20 work, thereby detecting the heat exchange amount of the evaporator 20. When there are multiple evaporators 20 to be detected, it is convenient to replace them.

[0044] like Figure 1 As shown, in some embodiments, the outer wall of the third housing assembly 300 is respectively fitted with the inner walls of the plurality of connection ports 120 to close the test cavity 110. In this way, the outer wall of the third housing assembly 300 is fitted with the inner wall of the connection port 120, and the first interface 320 and the second interface 330 of the third housing assembly 300 are penetrated through the connection port 120 and connected with the air inlet 220 and the air outlet 230, so that the test cavity 110 is closed. Thus, it is closer to the external environment of the air duct of the refrigerator, so that the heat exchange detected by the detection device 10 is closer to the heat exchange of the evaporator 20 when working in the refrigerator, and the reliability of the detection result is improved.

[0045] In some embodiments, the detection device 10 further includes a control device (not shown), which is connected to the first airflow generating assembly 400, and the control device can control the size of the airflow generated by the first airflow generating assembly 400. In this way, when the detection device 10 is detecting the heat exchange capacity of the evaporator 20, the tester can flexibly control the size of the airflow through the control device to better simulate the size of the airflow in the refrigerator. This improves the reliability of the detection structure of the detection device 10.

[0046] It should be noted that there may be many specific implementations of the control device, including but not limited to a PLC controller, a PID controller, and the like.

[0047] In some embodiments, the control device includes a memory and a processor. The memory is used to receive and store information. The processor is used to perform the above functions.

[0048] It should be noted that the processor may be a micro-controller unit (MCU), a central processing unit (CPU) or a digital signal processor (DSP), etc.

[0049] like Figure 2 As shown, in some embodiments, the detection assembly 500 includes a first humidity detector 510 and a second humidity detector 520, one of which is disposed on the inner wall of the air inlet 220 to detect the humidity of the incoming air. The other is disposed on the inner wall of the air outlet 230 to detect the humidity of the outgoing air. In this way, when the detection device 10 is working, the first humidity detector 510 and the second humidity detector 520 can respectively detect the humidity of the incoming air and the humidity of the outgoing air of the second housing assembly 200, thereby obtaining the humidity difference before and after the airflow passes through the evaporator 20.

[0050] It should be noted that one of the first humidity detector 510 and the second humidity detector 520 is arranged on the inner wall of the air inlet 220, and the other is arranged on the inner wall of the air outlet 230, including the first humidity detector 510 is arranged on the inner wall of the air inlet 220 and the second humidity detector 520 is arranged on the inner wall of the air outlet 230, or the second humidity detector 520 is arranged on the inner wall of the air inlet 220 and the first humidity detector 510 is arranged on the inner wall of the air outlet 230.

[0051] It should be noted that the first humidity detector 510 and the second humidity detector 520 may be one or more, which is not further limited herein.

[0052] like Figure 2 As shown, in some embodiments, the detection assembly 500 includes a first temperature detector 530 and a second temperature detector 540, one of which is disposed on the inner wall of the air inlet 220 to detect the temperature of the incoming air. The other is disposed on the inner wall of the air outlet 230 to detect the temperature of the outgoing air. In this way, when the detection device 10 is working, the first temperature detector 530 and the second temperature detector 540 can respectively detect the temperature of the air inlet 220 and the temperature of the air outlet 230 of the second housing assembly 200, so as to obtain the heat exchange amount of the evaporator 20 through the temperature difference between the air inlet 220 and the air outlet 230.

[0053] It should be noted that one of the first temperature detector 530 and the second temperature detector 540 is arranged on the inner wall of the air inlet 220, and the other is arranged on the inner wall of the air outlet 230, including the first temperature detector 530 is arranged on the inner wall of the air inlet 220 and the second temperature detector 540 is arranged on the inner wall of the air outlet 230, or the second temperature detector 540 is arranged on the inner wall of the air inlet 220 and the first temperature detector 530 is arranged on the inner wall of the air outlet 230.

[0054] It should be noted that the first temperature detector 530 and the second temperature detector 540 may be one or more, which is not further limited herein.

[0055] It should be noted that there are many specific implementations of the temperature detector, including a thermistor sensor, an infrared temperature detector, a gas temperature sensor, a semiconductor temperature sensor, and the like.

[0056] It should be noted that the above embodiments can complement each other if there is no conflict.

[0057] The components included in the "component", "device" and "equipment" disclosed in the present invention can also be flexibly combined, that is, modular production can be carried out according to actual conditions and modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device.

[0058] The division of the above components in the present disclosure is only one of the embodiments, for the convenience of reading, rather than limiting the scope of protection of the present disclosure. As long as the above components are included and have the same function, it should be understood that they are equivalent technical solutions of the present disclosure.

[0059] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0060] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
