Description

Technical Field

[0001] This invention relates to the technical field of testing range hoods and air conditioners, and particularly to a testing device, testing method, and storage medium for range hoods and air conditioners. Background Technology

[0002] A range hood air conditioner is a type of kitchen air conditioner used in conjunction with a range hood. It shares the same air duct as the range hood. The range hood air conditioner operates via the control panel of the range hood and does not have a separate control panel. In manufacturing, the range hood and range hood air conditioner are manufactured separately. The air duct around the condenser in the range hood air conditioner is shared with the range hood air duct. During assembly, the range hood air conditioner and range hood are joined and sealed together.

[0003] Before being put on the market, range hoods and air conditioners need to be tested to ensure they are fault-free. Current testing processes require pairing range hoods with existing ones, and employees must manually press various buttons on the range hoods, observe their operation, and manually judge the test results. This results in low efficiency, subjective and inaccurate results, and a lack of parameterized recording, making traceability difficult. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a testing method for range hoods and air conditioners, which can realize automatic testing of range hoods and air conditioners, and can quickly trace the fault location based on the output fault codes, thereby improving the maintenance efficiency of range hoods and air conditioners; and further improving the testing efficiency, accuracy and traceability of range hoods and air conditioners.

[0005] A testing method for a range hood / air conditioner includes: The testing process for the range hood and air conditioner is divided into M testing stages; M is an integer greater than 1. For each testing phase, tests are performed sequentially. If the test is passed, the process proceeds to the next testing phase; if the test fails, a fault code is output, and the process proceeds to the maintenance phase or to the next testing phase. The fault code consists of two codes arranged in sequence: the first code represents the current testing phase, and the second code represents the fault subclass.

[0006] In a preferred embodiment of the present invention, for each testing stage, the test is performed twice. If the first test fails, a fault code is output and the process enters the repair stage. After the repair, a second test is performed. If the second test passes, the process enters the next testing stage. If the second test fails, a fault code is output and the process enters the next testing stage. The fault code also includes a third code, which represents the current number of tests.

[0007] For each testing phase, the test is performed twice. If the first test fails, a fault code is output and the process enters the repair phase. After repair, a second test is performed. If the second test passes, the process enters the next testing phase. If the second test fails, a fault code is output and the process enters the next testing phase. The fault code also includes a third code, which represents the current number of tests.

[0008] In this application, if the first test fails in each testing phase, the range hood / air conditioner is repaired according to the fault code. After repair, a second test is conducted. This integrates repair and testing, allowing for simultaneous testing and repair. If the second test passes, the current testing phase is considered successful. This avoids the cumbersome process of the range hood / air conditioner going through testing, repair, and testing again after repair, improving both testing and repair efficiency. The fault codes in this application include the testing phase, number of tests, and fault subclass. These three codes can be arranged in a preset order, facilitating quick fault location by testing personnel and subsequent repairs.

[0009] In a preferred embodiment of the present invention, for each test stage, the test is performed twice. If the first test fails, a fault code is output and a second test is performed. If the second test passes, the test proceeds to the next test stage. If the second test fails, a fault code is output and the test proceeds to the next test stage. The fault code also includes a third code, which represents the current number of tests.

[0010] This application specifies that for each testing stage, if the first test fails, a second test is performed. These two tests are conducted to avoid testing errors and eliminate environmental interference, thereby improving testing accuracy. If both tests fail, the component corresponding to that stage is determined to be faulty, requiring entry into the repair stage, or until all testing stages are completed before entering the repair stage. The fault codes in this application include the testing stage, the number of tests, and the fault subclass. These three codes can be arranged in a preset order, facilitating quick fault location by testing personnel and simplifying subsequent repairs.

[0011] In a preferred embodiment of the present invention, the range hood air conditioner includes an air outlet, a control panel, an air guide plate, and a heat exchange assembly. The air guide plate is located in the air outlet and is connected to an air guide motor. The control panel covers the outside of the air outlet and is connected to a drive motor via a transmission assembly. The heat exchange assembly includes an evaporator, a compressor, and a condenser. The testing phase includes a mechanism testing phase, a swirling air testing phase, and a heat exchange testing phase. The mechanism testing phase is used to test the operating status of the drive motor and transmission components. The swirling air testing phase is used to test the operating status of the air guide motor and the operating angle of the air guide plate. The heat exchange testing phase is used to test the operating status of the evaporator, compressor, and condenser in the heat exchange components.

[0012] When the air conditioner is running, the drive motor, through a transmission assembly (such as a rack and pinion gear), moves the control panel away from the air outlet. Simultaneously, the air guide motor drives the air guide plate to rotate at a suitable angle for airflow, facilitating the output of cool or hot air into the room. When the air conditioner stops running, the air guide motor drives the air guide plate to the closed position, and the drive motor, through the transmission assembly, moves the control panel closer to the air outlet until the control panel covers the outlet, protecting it. In this application, the heat exchange components include conventional air conditioning components for cooling or heating, such as an evaporator, condenser, and compressor. The application's testing phase tests the operating status of the drive and transmission assemblies; the air sweeping test phase tests the operating status of the air guide motor and the operating angle of the air guide plate; and the heat exchange test phase tests the operating status of the evaporator, compressor, and condenser within the heat exchange components. These three test phases correspond to the operation of the control panel, air guide plate, and heat exchange components, and are performed sequentially during the air conditioner's startup and operation, completely simulating each stage of the range hood air conditioner's startup and operation. The operating status of the evaporator, compressor and condenser can be monitored by their corresponding voltage and current. If the voltage and / or current deviate from the preset range, a fault is determined to have occurred.

[0013] In a preferred embodiment of the present invention, the heat exchange assembly further includes an internal fan and an external fan, the internal fan being located on the side of the evaporator; the external fan being located on the side of the condenser, the external fan causing outdoor air to pass through the condenser and be discharged into the flue duct; The heat exchange test phase is also used to test the rotational speed of the internal fan and the external fan.

[0014] In this application, the internal fan is used to guide the cold air from the evaporator side to the air outlet, thus forming the air outlet duct between the evaporator and the air outlet; the external fan is used to guide the hot air from the condenser side to the exhaust duct, thus forming the air outlet duct between the condenser and the exhaust duct. During the heat exchange stage, the speeds of both the internal and external fans are tested simultaneously to ensure smooth airflow in the corresponding exhaust ducts.

[0015] In a preferred embodiment of the present invention, a simulation fixture is provided on the side of the range hood air conditioner. The simulation fixture is used to simulate the wind speed in the air duct of the range hood, and the wind speed is set with multiple levels. During the heat exchange test phase, the simulation fixture adjusts the wind speed by increasing or decreasing the speed, and tests the operating status of the evaporator, compressor, and condenser, as well as the rotational speed of the internal and external fans.

[0016] This application uses a simulated fixture to control the airflow speed in the range hood duct. This is because, in actual use, the condenser's outlet duct is shared with the range hood duct, and the range hood operates at different speeds, resulting in varying suction power within the duct. Therefore, this application needs to consider this dynamic change when testing the range hood to ensure that the fan speed setting does not affect its normal operation. During the heat exchange testing phase, the simulated fixture undergoes speed adjustments (both increasing and decreasing) and fixed-speed operation to test the operating status of the evaporator, compressor, and condenser under different conditions, as well as the rotational speeds of the internal and external fans. This verifies the stability of the range hood fan under transient load changes, and the application scenarios cover various scenarios of integrated range hood and range hood air conditioning products.

[0017] In a preferred embodiment of the present invention, the heat exchange assembly further includes a water pump motor, and a coolant container is provided on the outside of the condenser. The water pump motor is located inside the coolant container and is used to circulate and spray the coolant from the bottom of the coolant container to the outside of the condenser. The heat exchange test phase is also used to test the operating status of the water pumping motor.

[0018] In this application, a water-pumping motor draws coolant from the condensate solution and sprays it onto the outside of the condenser to improve the condenser's heat exchange efficiency. During the heat exchange testing phase, the operating status of the water-pumping motor is tested. The operating status of the water-pumping motor can be monitored by its corresponding voltage and current; if the voltage and / or current deviate from the preset range, a fault is determined. In actual operation, the operating status of the water-pumping motor can also be easily judged by listening to sounds, as a fault does not affect the normal operation of the entire heat exchange assembly.

[0019] In a preferred embodiment of the present invention, the heat exchange test stage is also used to test the temperature of the compressor intake pipe, the temperature of the compressor exhaust pipe, the fin temperature in the evaporator, the fin temperature in the condenser, and the indoor ambient temperature.

[0020] In the heat exchange testing phase, this application, in addition to detecting the operational status of each component, also includes temperature parameters such as the compressor inlet pipe temperature, compressor outlet pipe temperature, evaporator fin temperature, condenser fin temperature, and indoor ambient temperature within the detection range, forming a closed loop of motion state-environment feedback. This application does not use multiple temperature parameters as auxiliary data, but rather as core judgment criteria, directly correlated with the cooling effect, to verify the synergistic performance of the range hood and its air conditioner. In this application, the temperatures of the compressor inlet pipe, compressor outlet pipe, evaporator fin, condenser fin, and indoor ambient temperature can be obtained through temperature sensors installed at corresponding locations.

[0021] In a preferred embodiment of the present invention, the operating status of the evaporator, compressor, and condenser is determined by measuring the corresponding voltage and / or current values ​​of the evaporator, compressor, and condenser; when the voltage and / or current values ​​of the evaporator, compressor, and condenser deviate from a preset range, the evaporator, compressor, and condenser are determined to be faulty.

[0022] The operating status of each device is determined by current and / or voltage values. The monitoring method is efficient and convenient, requiring no additional detection devices or equipment, and can quickly determine whether the operating status is normal.

[0023] The second objective of this application is to provide a computer storage medium, the storage medium including a stored program, and a processor executing the program to implement a testing method for a range hood air conditioner as described above.

[0024] The third objective of this application is to provide a testing device for a range hood / air conditioner, comprising a receiving module, an execution module, a storage module, and a processor; wherein, the receiving module is used to receive communication signals and test data from the range hood / air conditioner; the execution module is used to start and execute the test program; the storage module records and stores test process parameter data and test judgment results; and the processor is used to execute the testing method for a range hood / air conditioner as described above.

[0025] The beneficial effects of this invention are as follows: This invention provides a testing method for range hoods and air conditioners, comprising: dividing the testing process of the range hood and air conditioner into M testing stages; performing tests sequentially for each testing stage; if the test is qualified, proceeding to the next testing stage; if the test fails, outputting a fault code, and proceeding to the maintenance stage or the next testing stage; the fault code includes two codes arranged sequentially, the first code representing the current testing stage, and the second code representing the fault subclass. This application can realize automatic testing of range hoods and air conditioners, and can quickly trace the fault location based on the output fault code, improving the maintenance efficiency of range hoods and air conditioners; thereby improving the testing efficiency, accuracy, and traceability of range hoods and air conditioners.

[0026] This application also provides a computer storage medium, the storage medium including a stored program, the processor executing the program to implement the above-described testing method for a range hood and air conditioner; it can realize automatic testing of the range hood and air conditioner, and can quickly trace the fault location based on the output fault code, thereby improving the maintenance efficiency of the range hood and air conditioner; and thus improving the testing efficiency, accuracy and traceability of the range hood and air conditioner.

[0027] This application also provides a testing device for a range hood / air conditioner, including a receiving module, an execution module, a storage module, and a processor. The receiving module receives communication signals and test data from the range hood / air conditioner. The execution module initiates and executes the test program. The storage module records and stores test process parameter data and test results. The processor executes the aforementioned testing method for a range hood / air conditioner. This testing device enables automatic testing of range hoods / air conditioners, allowing for rapid tracing of fault locations based on output fault codes, thus improving the maintenance efficiency of range hoods / air conditioners and enhancing the testing efficiency, accuracy, and traceability.

[0031] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Example 1 This application provides a testing method for a range hood / air conditioner, including: The testing process for the range hood and air conditioner is divided into M testing stages; M is an integer greater than 1. For each testing phase, tests are performed sequentially. If the test is passed, the process proceeds to the next testing phase; if the test fails, a fault code is output, and the process proceeds to the maintenance phase or to the next testing phase. The fault code consists of two codes arranged in sequence: the first code represents the current testing phase, and the second code represents the fault subclass.

[0033] In this application, the testing phase is divided according to the order in which the various components of the range hood and air conditioner operate. For example, the testing phase is divided according to the operation of the control panel, the operation of the air guide plate, and the operation of heat exchange components such as the evaporator, condenser, and compressor.

[0034] In this application, the testing phase can also be divided according to the location of each component in the range hood and air conditioner, such as testing components located inside the air conditioner panel and testing components located in the air conditioner panel.

[0035] In this application, the M test stages can be performed automatically and sequentially. After each test stage, if the test fails, the process can proceed to the maintenance stage for repair of the corresponding part, and then return to the test stage. Alternatively, all test stages can be completed sequentially, and the corresponding part can be repaired based on the output fault codes.

[0036] In this application, maintenance personnel can quickly trace the cause of a fault based on the fault code. Since the components tested in each testing phase are specific, the approximate range of faulty components can be determined based on the testing phase in the fault code, and the specific faulty component can be determined based on the code representing the fault subclass.

[0037] In this application, the types of components tested in each testing phase are pre-set, and the fault subclasses are also pre-defined. Therefore, the location of the fault can be quickly traced based on the fault code, improving maintenance efficiency.

[0038] This application enables automatic testing of range hoods and air conditioners, and can quickly trace the fault location based on the output fault codes, thereby improving the maintenance efficiency of range hoods and air conditioners; and further improving the testing efficiency, accuracy and traceability of range hoods and air conditioners.

[0039] This application also provides a computer storage medium, the storage medium including a stored program, the processor executing the program to implement the above-described testing method for a range hood and air conditioner; it can realize automatic testing of the range hood and air conditioner, and can quickly trace the fault location based on the output fault code, thereby improving the maintenance efficiency of the range hood and air conditioner; and thus improving the testing efficiency, accuracy and traceability of the range hood and air conditioner.

[0040] Example 2 This application provides a testing method for a range hood / air conditioner, including: The testing process for the range hood and air conditioner is divided into M testing stages; M is an integer greater than 1. For each testing phase, tests are performed sequentially. If the test is passed, the process proceeds to the next testing phase; if the test fails, a fault code is output, and the process proceeds to the maintenance phase or to the next testing phase. The fault code consists of two codes arranged in sequence: the first code represents the current testing phase, and the second code represents the fault subclass.

[0041] Furthermore, for each testing phase, the test is performed twice. If the first test fails, a fault code is output and the process enters the repair phase. After repair, a second test is performed. If the second test passes, the process enters the next testing phase. If the second test fails, a fault code is output and the process enters the next testing phase. The fault code also includes a third code, which represents the current number of tests.

[0042] In this application, if the first test fails in each testing phase, the range hood / air conditioner is repaired according to the fault code. After repair, a second test is conducted. This integrates repair and testing, allowing for simultaneous testing and repair. If the second test passes, the current testing phase is considered successful. This avoids the cumbersome process of the range hood / air conditioner going through testing, repair, and testing again after repair, improving both testing and repair efficiency. The fault codes in this application include the testing phase, number of tests, and fault subclass. These three codes can be arranged in a preset order, facilitating quick fault location by testing personnel and subsequent repairs.

[0043] Furthermore, for each testing phase, the test is performed twice. If the first test fails, an error code is output, and a second test is performed. If the second test passes, the test proceeds to the next testing phase. If the second test fails, an error code is output, and the test proceeds to the next testing phase. The error code also includes a third code, which represents the current number of tests.

[0044] This application specifies that for each testing stage, if the first test fails, a second test is performed. These two tests are conducted to avoid testing errors and eliminate environmental interference, thereby improving testing accuracy. If both tests fail, the component corresponding to that stage is determined to be faulty, requiring entry into the repair stage, or until all testing stages are completed before entering the repair stage. The fault codes in this application include the testing stage, the number of tests, and the fault subclass. These three codes can be arranged in a preset order, facilitating quick fault location by testing personnel and simplifying subsequent repairs.

[0045] Furthermore, the range hood air conditioner includes an air outlet, a control panel, an air guide plate, and a heat exchange assembly. The air guide plate is located in the air outlet and is connected to an air guide motor. The control panel covers the outside of the air outlet and is connected to a drive motor via a transmission assembly. The heat exchange assembly includes an evaporator, a compressor, and a condenser. The testing phase includes a mechanism testing phase, a swirling air testing phase, and a heat exchange testing phase. The mechanism testing phase is used to test the operating status of the drive motor and transmission components. The swirling air testing phase is used to test the operating status of the air guide motor and the operating angle of the air guide plate. The heat exchange testing phase is used to test the operating status of the evaporator, compressor, and condenser in the heat exchange components.

[0046] When the air conditioner is running, the drive motor, through a transmission assembly (such as a rack and pinion gear), moves the control panel away from the air outlet. Simultaneously, the air guide motor drives the air guide plate to rotate at a suitable angle for airflow, facilitating the output of cool or hot air into the room. When the air conditioner stops running, the air guide motor drives the air guide plate to the closed position, and the drive motor, through the transmission assembly, moves the control panel closer to the air outlet until the control panel covers the outlet, protecting it. In this application, the heat exchange components include conventional air conditioning components for cooling or heating, such as an evaporator, condenser, and compressor. The application's testing phase tests the operating status of the drive and transmission assemblies; the air sweeping test phase tests the operating status of the air guide motor and the operating angle of the air guide plate; and the heat exchange test phase tests the operating status of the evaporator, compressor, and condenser within the heat exchange components. These three test phases correspond to the operation of the control panel, air guide plate, and heat exchange components, and are performed sequentially during the air conditioner's startup and operation, completely simulating each stage of the range hood air conditioner's startup and operation. The operating status of the evaporator, compressor and condenser can be monitored by their corresponding voltage and current. If the voltage and / or current deviate from the preset range, a fault is determined to have occurred.

[0047] Furthermore, the heat exchange assembly also includes an internal fan and an external fan, the internal fan being located on the side of the evaporator; the external fan being located on the side of the condenser, the external fan causing outdoor air to pass through the condenser and be discharged into the flue duct; The heat exchange test phase is also used to test the rotational speed of the internal fan and the external fan.

[0048] In this application, the internal fan is used to guide the cold air from the evaporator side to the air outlet, thus forming the air outlet duct between the evaporator and the air outlet; the external fan is used to guide the hot air from the condenser side to the exhaust duct, thus forming the air outlet duct between the condenser and the exhaust duct. During the heat exchange stage, the speeds of both the internal and external fans are tested simultaneously to ensure smooth airflow in the corresponding exhaust ducts.

[0049] Furthermore, a simulation fixture is provided on the side of the range hood air conditioner. The simulation fixture is used to simulate the wind speed in the range hood duct, and the wind speed is set with multiple levels. During the heat exchange test phase, the simulation fixture adjusts the wind speed by increasing or decreasing the speed, and tests the operating status of the evaporator, compressor, and condenser, as well as the rotational speed of the internal and external fans.

[0050] This application uses a simulated fixture to control the airflow speed in the range hood duct. This is because, in actual use, the condenser's outlet duct is shared with the range hood duct, and the range hood operates at different speeds, resulting in varying suction power within the duct. Therefore, this application needs to consider this dynamic change when testing the range hood to ensure that the fan speed setting does not affect its normal operation. During the heat exchange testing phase, the simulated fixture undergoes speed adjustments (both increasing and decreasing) and fixed-speed operation to test the operating status of the evaporator, compressor, and condenser under different conditions, as well as the rotational speeds of the internal and external fans. This verifies the stability of the range hood fan under transient load changes, and the application scenarios cover various scenarios of integrated range hood and range hood air conditioning products.

[0051] Furthermore, the heat exchange assembly also includes a water pump motor, and a coolant container is provided on the outside of the condenser. The water pump motor is located inside the coolant container and is used to circulate and spray the coolant at the bottom of the coolant container to the outside of the condenser. The heat exchange test phase is also used to test the operating status of the water pumping motor.

[0052] In this application, a water-pumping motor draws coolant from the condensate solution and sprays it onto the outside of the condenser to improve the condenser's heat exchange efficiency. During the heat exchange testing phase, the operating status of the water-pumping motor is tested. The operating status of the water-pumping motor can be monitored by its corresponding voltage and current; if the voltage and / or current deviate from the preset range, a fault is determined. In actual operation, the operating status of the water-pumping motor can also be easily judged by listening to sounds, as a fault does not affect the normal operation of the entire heat exchange assembly.

[0053] Furthermore, the heat exchange test stage is also used to test the temperature of the compressor intake pipe, the temperature of the compressor exhaust pipe, the fin temperature in the evaporator, the fin temperature in the condenser, and the indoor ambient temperature.

[0054] In the heat exchange testing phase, this application, in addition to detecting the operational status of each component, also includes temperature parameters such as the compressor inlet pipe temperature, compressor outlet pipe temperature, evaporator fin temperature, condenser fin temperature, and indoor ambient temperature within the detection range, forming a closed loop of motion state-environment feedback. This application does not use multiple temperature parameters as auxiliary data, but rather as core judgment criteria, directly correlated with the cooling effect, to verify the synergistic performance of the range hood and its air conditioner. In this application, the temperatures of the compressor inlet pipe, compressor outlet pipe, evaporator fin, condenser fin, and indoor ambient temperature can be obtained through temperature sensors installed at corresponding locations.

[0055] Furthermore, the operating status of the evaporator, compressor, and condenser is determined by measuring the corresponding voltage and / or current values ​​of the evaporator, compressor, and condenser; when the voltage and / or current values ​​of the evaporator, compressor, and condenser deviate from the preset range, the evaporator, compressor, and condenser are determined to be faulty.

[0056] The operating status of each device is determined by current and / or voltage values. The monitoring method is efficient and convenient, requiring no additional detection devices or equipment, and can quickly determine whether the operating status is normal.

[0057] Example 3 like Figure 1 As shown, the range hood air conditioner in this application includes an air outlet, a control panel, an air guide plate, and a heat exchange assembly. The air guide plate is located in the air outlet and is connected to an air guide motor. The control panel covers the outside of the air outlet and is connected to a drive motor via a transmission assembly; the transmission assembly can be a gear and rack transmission assembly or similar. The heat exchange assembly includes an evaporator, a compressor, a condenser, an internal fan, an external fan, an outlet fan, and a water pump motor. The internal fan is used to guide the cold air from the side of the evaporator to the air outlet, forming an outlet air duct between the evaporator and the air outlet. The external fan is used to guide the hot air from the side of the condenser to the range hood duct for exhaust, forming an outlet air duct between the condenser and the range hood duct. The outlet fan is located on the side of the air outlet and is used to blow the cold air that has passed through the condenser out of the air outlet, forming an air duct at the air outlet to ensure that the cold air is blown out at a set angle. A coolant container is located on the outside of the condenser, and the water pump motor is located inside the coolant container to circulate and spray the coolant from the bottom of the container to the outside of the condenser. Smoke from the range hood's extraction port is guided by the exhaust fan into the hood's ductwork for discharge.

[0058] To accommodate the structure and operating status of the aforementioned range hood and air conditioner, this application divides the testing process of the range hood and air conditioner into three testing stages based on operating time: a mechanism testing stage, a sweeping air testing stage, and a heat exchange testing stage. The mechanism testing stage tests the operating status of the drive and transmission components; the sweeping air testing stage tests the operating status of the air guide motor and the operating angle of the air guide plate; and the heat exchange testing stage tests the operating status of the evaporator, compressor, condenser, and water pump motor, as well as the rotational speeds of the internal fan, external fan, and outlet fan, and the temperatures of the compressor inlet pipe, compressor exhaust pipe, evaporator fins, condenser fins, and indoor ambient temperature.

[0059] In this embodiment, the fault codes include three codes arranged in sequence. The first code represents the current test phase, the second code represents the current test number, and the third code represents the fault subclass.

[0060] The testing device for the range hood air conditioner of this application includes a receiving module, an execution module, a storage module, and a processor, such as... Figure 2 The system comprises several modules: a receiving module to receive communication signals and test data from the range hood and air conditioner; an execution module to start and execute the test program; a storage module to record and store test parameters and results; and a processor to process all instructions and data. During the testing process, the range hood and air conditioner are connected to the testing device, which in turn connects to a network platform to transmit the output test results for viewing by staff.

[0061] The testing device in this application needs to be used in conjunction with a simulation fixture during the testing process. The simulation fixture is used to simulate the wind speed in the range hood duct, and the wind speed is set with multiple levels. During the heat exchange test phase, the simulation fixture adjusts the wind speed by increasing or decreasing the levels, and tests the operating status of the evaporator, compressor, and condenser, as well as the rotational speed of the indoor and outdoor fans. This is because in the actual use of range hoods and air conditioners, the condenser's air outlet duct is shared with the range hood duct, and the range hood will have different speed settings during use. The suction power in the range hood duct corresponding to different speed settings is different. Therefore, when testing range hoods and air conditioners, this application needs to consider this dynamic change to ensure that the wind speed setting of the range hood does not affect the normal operation of the range hood and air conditioner.

[0062] like Figure 3 As shown, this application provides a testing method for a range hood / air conditioner, comprising: The assembled range hood and air conditioner are brought to the testing station. The product information is automatically identified and logged in via barcode scanning. The communication cable of the range hood and air conditioner is then connected to the communication port of the testing device. Barcode scanning refers to scanning the identification code inside the range hood and air conditioner casing. This code contains information such as the model number of the range hood and air conditioner. Each model corresponds to a pre-set test program. After scanning the code, the corresponding test program for that model can be obtained. The communication cable of the range hood and air conditioner is then connected to the communication port of the testing device. The testing equipment and the range hood / air conditioner are powered on; Turn on the automatic test switch of the test device to enter the test program; Upon entering the range hood air conditioning mechanism testing phase, the drive motor, via a transmission assembly (such as a rack and pinion gear), moves the control panel away from the air outlet. The current and voltage of the drive motor are monitored to determine its operating status; the positional changes of the rack and pinion gear are also monitored to determine their operational status. If the test is successful, the system proceeds to the air sweeping test phase. If the drive motor test fails, fault code 1.1.1 is output, where the first '1' indicates the current state of the first test phase, the second '1' indicates the first test, and the third '1' indicates a drive motor malfunction. If the rack and pinion test fails, fault code 1.1.2 is output, where the first '1' indicates the current state of the first test phase, the second '1' indicates the first test, and the third '2' indicates a rack and pinion malfunction. After the tester troubleshoots and repairs the issue, a second test is initiated, entering the mechanism testing phase for retesting. If the second test is successful, the system proceeds to the air sweeping test phase; if the drive motor test still fails the second time, fault code 1.2.1 is output, where the first '1' indicates the current state of the first test phase, the second '2' indicates the second test, and the third '1' indicates a drive motor malfunction. If the second test of the gear and rack still fails, fault code 1.2.2 will be output, where the first 1 indicates that the first test stage is underway, the second 2 indicates the second test, and the third 2 indicates a gear and rack fault; then the swing test stage will begin.

[0063] The air-sweeping test program runs, the air guide motor starts, and the air guide plate swings to perform air sweeping. The current and voltage of the air guide motor are checked to determine if its operation is normal; the swing angle of the air guide plate is checked to determine if its operation angle is normal. If the test is successful, the heat exchange test phase begins; if the air guide motor test fails, exception code 2.1.1 is output; where the first 2 indicates the current phase is the second test, the second 1 indicates the first test, and the third 1 indicates a fault in the air guide motor. If the air guide plate test fails, exception code 2.1.2 is output; where the first 2 indicates the current phase is the second test, the second 1 indicates the first test, and the third 2 indicates a fault in the air guide plate. After the tester troubleshoots and repairs, the test phase is restarted and retested, entering the air-sweeping retest phase, and recorded as the second air-sweeping test phase. If the second test is successful, the cooling test begins; if the air guide motor test fails, exception code 2.2.1 is output; where the first 2 indicates the current phase is the second test, the second 2 indicates the second test, and the third 1 indicates a fault in the air guide motor. If the air guide plate fails the test, an error code 2.2.2 will be output. The first 2 indicates that the test is in the second stage, the second 2 indicates the second test, and the third 2 indicates that the air guide plate is faulty. Then the cooling test will begin.

[0064] The heat exchange test program runs, starting the indoor fan, outdoor fan, outlet fan, compressor, and water pump motor to begin cooling and blow out cold air. The simulated fixture automatically adjusts the fan speed according to levels 1, 2, and 3. The operating status of the evaporator, compressor, condenser, and water pump motor, as well as the speeds of the indoor fan, outdoor fan, and outlet fan, and the temperatures of the compressor inlet pipe, compressor outlet pipe, evaporator fins, condenser fins, and indoor ambient temperature are monitored. If the current and voltage of the evaporator, compressor, condenser, and water pump motor are normal, they are considered to be operating normally. If the speeds of the indoor fan, outdoor fan, and outlet fan are within the preset range, they are considered to be operating normally. If the temperatures of the compressor inlet pipe, compressor outlet pipe, evaporator fins, condenser fins, and indoor ambient temperature are within the preset range, the temperature parameters are considered normal. The heat exchange test is then determined to be qualified and recorded as the first heat exchange test. If all tests pass, the comprehensive test results will be displayed. If the operating status of the evaporator, compressor, condenser and water pump motor is not up to standard, fault codes 3.1.1, 3.1.2, 3.1.3 and 3.1.4 will be output respectively; where the first 3 represents the current third test stage, the second 1 represents the first test, and the third code represents the faults of the evaporator (1), compressor (2), condenser (3) and water pump motor (4) respectively; if the speed of the internal fan, external fan and outlet fan exceeds the preset range, fault codes 3.1.5, 3.1.6 and 3.1.7 will be output respectively; where the first 3 represents the current third test stage, the second 1 represents the first test, and the third code represents the faults of the internal fan (5), external fan (6) and outlet fan (7) respectively. If the temperature of the compressor intake pipe, the temperature of the compressor exhaust pipe, the temperature of the evaporator fins, the temperature of the condenser fins, and the indoor ambient temperature exceed the preset range, fault codes 3.1.8, 3.1.9, 3.1.10, 3.1.11, and 3.1.12 will be output respectively. Among them, the first 3 represents that the current test stage is in the third test stage, the second 1 represents the first test, and the third code represents the abnormal temperature of the compressor intake pipe (8), the temperature of the compressor exhaust pipe (9), the temperature of the evaporator fins (10), the temperature of the condenser fins (11), and the indoor ambient temperature (12). After the tester investigates the cause and repairs, the test stage is restarted and the heat exchange retest is entered, and it is recorded as the second heat exchange test. If the second test is qualified, the comprehensive test result is displayed; if the second heat exchange test is still unqualified, the corresponding fault code is output, and then the comprehensive test result is displayed.

[0065] The comprehensive test result includes the results of each stage of the test. If all stages of the test are passed, the comprehensive test result is qualified; otherwise, the comprehensive test result is unqualified. The unqualified items will be displayed in detail to facilitate technicians in troubleshooting and repair.

[0066] The test process data is transmitted and recorded on the network platform, and the test data can be traced and queried.

[0067] Example 4 The difference from Example 3 is that the test procedure in this example does not include the test of the water pump motor. The operating status of the water pump motor is only judged by visual inspection and sound during the test of the range hood and air conditioner.

[0068] Example 5 The difference from Example 3 is that the test procedure in this example does not include the test of the air outlet fan. The operating status of the air outlet fan is only determined by the human perception of the air outlet wind speed during the test of the range hood and air conditioner.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components.
