[0029] Furthermore, the kitchen appliances in the embodiments of the present invention may be dishwashers, dryers, or even cooking equipment such as integrated stoves and multi-function all-in-one machines. The specific use shall be subject to actual usage, and the embodiments of the present invention are not limited to this.

[0030] For ease of understanding, Figure 1 A structural block diagram of a test device is shown, such as Figure 1 As shown, the testing device in the embodiment of the present invention includes: a detection device 10 and a fixing device 20.

[0031] The fixing device 20 is used to fix the control board to be tested ( Figure 1(not shown in the figure), the control board to be tested is the control board of a kitchen appliance; the detection device 10 is used to connect to the control board to be tested to simulate the actual working signal of the kitchen appliance and generate an analog signal, transmit the analog signal to the control board to be tested, and indicate the response signal generated after the control board to be tested responds to the analog signal, thereby allowing maintenance personnel to check whether the function of the control board to be tested is normal through the indication, and when a fault occurs, the fault type can be effectively determined.

[0032] Furthermore, the above-mentioned detection device includes: a power supply module, a detection module, a test switch assembly and an indication module; wherein the power supply module is used to supply power to the test equipment; the test switch assembly is used to respond to the selection operation for the test function, generate an analog signal of the sensor of the kitchen appliance corresponding to the test function, and transmit the analog signal to the control board to be tested; the detection module is used to output an output signal corresponding to the response signal generated after the control board to be tested responds to the analog signal; and the indication module is used to indicate based on the output signal.

[0033] Therefore, the above-mentioned testing equipment of the embodiment of the utility model can be used to test the control function of the control board to be tested.

[0034] In actual use, the detection device is configured with a housing within which the detection device is disposed; a fixing device is disposed at a predetermined position outside the housing. When the control board to be tested is secured to the fixing device, a fixing fixture can be used to secure the control board to be tested, and a wiring harness can be used to connect the control board to the detection device, thereby conveniently and quickly securing the control board to be tested.

[0035] Moreover, the control board to be tested in the embodiment of the present invention can be different types of control boards of the same kitchen appliance, or control boards of different kitchen appliances. The specific use shall be based on actual usage, and the embodiment of the present invention is not limited to this.

[0036] Furthermore, in order to enable the detection device to simulate the actual working signals of kitchen appliances and generate simulated signals corresponding to the actual working signals, the above-mentioned detection device can generally be configured according to the corresponding kitchen appliances. For example, taking a dishwasher as an example, the detection device may include other circuit boards in addition to the dishwasher control board. These circuit boards can constitute a detection module to simulate the actual working signals of the corresponding functions.

[0037] Furthermore, the above-mentioned test switch assembly includes at least one test control, and each test control corresponds to a test function of the test device.

[0038] To facilitate understanding, taking a dishwasher as an example, usually, several commonly used test functions of the dishwasher's control panel include a drain pump, a water inlet pump, a water diversion valve, drying and heating, various sensor signals, and switch signals, etc. Therefore, for the dishwasher's test equipment, a corresponding test control can be configured for each test function, and the corresponding sensor signal can be simulated to output the corresponding analog signal and transmit it to the control board to be tested. The control board to be tested can respond to the analog signal, thereby enabling the detection module to simulate the actual working signal of the dishwasher and detect the response and functional output of the control board to be tested to determine whether the control board to be tested has a fault, as well as the type of fault, etc.

[0039] Furthermore, the above-mentioned indication module usually includes an indication unit corresponding to each test function, specifically, such as an indicator light, which can be used to display the output of each function of the control board, and the fault location can be determined by the function represented by the indicator light.

[0040] Furthermore, the above-mentioned testing equipment also includes an interactive panel connected to the detection device; the interactive panel is used to respond to the start operation after determining the test function, generate a start signal, send the start signal to the detection device and the control board to be tested, so that the detection device and the control board to be tested are started, and the test function is tested; and, the test process of the test function is displayed.

[0041] Specifically, the interactive panel includes an interactive control and a display unit; the interactive control is used to respond to the start operation; and the display unit is used to display the test process of the test function.

At the same time, the interactive panel usually includes a main chip, and a characteristic test program can be burned into the main chip to control the interactive controls and display units, thereby realizing automatic control of the functional output of the control board to be tested.

[0043] Furthermore, for ease of understanding, Figure 1 On the basis of Figure 2 A schematic diagram of the three-dimensional structure of a test device is also shown. Taking a dishwasher as an example, the test device is further explained. Figure 2 As shown, it includes a housing 201 and a fixing device 20, and the detection device is located in the cavity of the housing 201. Further, Figure 2 Also shown are an interactive panel 202, an interactive control 203 and a display unit 204, as well as a power module 205, a plurality of test controls 206 of the test switch assembly, and a plurality of indication units 207 of the indication module.

[0044] further, Figure 2In the embodiment, the fixing device 20 is in the form of a fixing bracket, and the fixing device 20 is also provided with a protective cover plate; the protective cover plate is used to provide safety protection for the control board to be tested fixed to the fixing device.

The second cover 209 is disposed on one side of the fixture and extends to the surface of the housing. The first cover is openable and closable relative to the fixture.

[0045] In actual use, the above-mentioned second cover plate is arranged on the side of the fixing device and used as a side plate, that is, the first cover plate and the second cover plate are arranged in an "L" shape, which can provide safety protection for the entire test equipment. In addition, the first cover plate and the second cover plate can be made of transparent insulating materials, such as acrylic plates, etc., which will not increase the weight of the test equipment too much while providing safety protection.

[0046] Furthermore, a first through hole and a second through hole are provided at preset positions of the shell; the test switch assembly is provided on the outer surface of the shell corresponding to the first through hole; and the indication module is provided on the outer surface of the shell corresponding to the second through hole.

[0047] In addition, the above-mentioned shell can also be provided with other through holes, such as wiring harness through holes, etc., which can be specifically set according to actual usage conditions, and the embodiment of the present utility model does not limit this.

[0048] Furthermore, considering that dishwashers are usually equipped with a washing pump, the above Figure 2 In the embodiment, a washing pump motor 210 is also provided, which can be used as a part of the detection module to test the motor control function of the control board to be tested.

[0049] Further, based on Figure 2 The test equipment shown, Figure 3 A functional schematic diagram of a test device is also shown, such as Figure 3 As shown, it includes a test device 300 and a control board 301 to be tested, as well as an interactive panel 202 , a power module 205 , an indication unit 207 , a test control 206 , and a washing pump motor 210 .

[0050] Taking the dishwasher as an example, Figure 3 In the example, the power module 205 can input AC 220V voltage and transmit it to the control board to be tested, that is, Figure 3 The interaction between the test device 300 and the control board 301 under test includes the interaction of the AC220V voltage signal. Figure 3As shown, taking a dishwasher as an example, the interaction between the test device 300 and the control board 301 to be tested also includes the response signal generated after the control board to be tested responds to the analog signal, including the drain pump signal, the water inlet valve signal, the water softening signal, the water diversion valve signal, the drying and heating signal, the sensor signal and the switch signal, etc. After these signals are transmitted to the detection module, the detection module can output the corresponding output signal, and then indicate it through the indication unit of the indication module.

[0051] Therefore, based on Figure 2 and Figure 3 Taking a dishwasher as an example, the test process of the test equipment of the embodiment of the present invention may include the following steps:

[0054] (3) Connect the interactive panel, which can automatically control the functional output of the control board to be tested by burning a specific test program into the interactive panel.

[0055] (4) Turn on the power of the test equipment. After the product is powered on, press the start interactive control on the interactive panel, and the test equipment will begin functional testing and fault diagnosis; through the test control in the test switch assembly, the sensing and control signals of the dishwasher are simulated, so that the control board to be tested starts the corresponding functional output.

[0056] (5) The indicator light on the test equipment corresponding to the functional output will light up. If the indicator light does not light up, it means that the corresponding functional output is abnormal. Maintenance personnel can quickly identify and judge the fault based on the test results of the test equipment, and take targeted maintenance measures for the control board under test.
