Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 shows a flow chart of a method of testing a pressure cooking appliance according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a method for testing a pressure cooking appliance, which may be, for example, an electric pressure cooker, and the method may include the following steps:
and step S110, acquiring the bottom temperature of the pot body detected by a temperature detection device arranged at the bottom of the pot body of the pressure cooking appliance.
The temperature detection device arranged at the bottom of the pot body can be a temperature sensor for detecting the bottom temperature of the pot body.
In step S110, the bottom temperature of the pot body detected by the temperature detection device can be determined according to the bottom temperature detection signal output by the temperature detection device.
And step S120, acquiring the internal pressure of the pot body detected by a pressure detection device arranged on the upper cover of the pressure cooking appliance.
The pressure detection device arranged on the upper cover of the pressure cooking appliance is used for detecting and feeding back the internal pressure of the pot body. The pressure detection device can be a pressure sensor or a temperature sensor, the pressure sensor can be directly used for detecting the internal pressure of the pot body, the temperature sensor can be used for detecting the temperature of the water vapor in the pot body, the temperature of the water vapor in the pot body corresponds to the internal pressure of the pot body, and therefore under the condition that the temperature of the water vapor in the pot body is known, the internal pressure of the corresponding pot body can be determined.
In step S120, the internal pressure of the pot body detected by the pressure detection device may be determined according to the pressure detection signal output by the pressure detection device.
And S130, acquiring the pressure state inside the pot body fed back by the zero pressure detection device, wherein the pressure state comprises a pressure starting state and a non-pressure starting state.
In the pressure cooking appliance, the zero pressure detecting means may include a zero pressure float and a zero pressure detecting element. The zero pressure float is movably arranged on the upper cover of the pressure cooking appliance along the up-down direction, and a magnetic part can be arranged on the zero pressure float. The zero pressure detection element may be a feeler element disposed above the zero pressure float. When the pressure inside the pot body is raised, the zero pressure floater moves upwards, and the movement of the zero pressure floater drives the magnetic part to move, so that the magnetic field intensity of the position of the zero pressure detection element changes, and the change of the pressure state inside the pot body can be reflected according to the change of the magnetic field intensity of the zero pressure detection element.
Step S140, testing the pressure cooking appliance according to the bottom temperature, the internal pressure and the pressure state.
In the process of testing and running of the pressure cooking appliance, the pressure state of the inside of the pot body, which is fed back by the temperature detection device, the internal pressure detected by the pressure detection device and the zero pressure detection device, is obtained in real time, whether the corresponding device and the associated parts are abnormal or not can be determined, and the automatic test of the pressure cooking appliance is realized.
When the pressure cooking appliance is tested by using the testing method of the pressure cooking appliance provided by the embodiment of the invention, a cooking function can be selected, and whether each part in the pressure cooking appliance is abnormal or not can be detected in real time in the process of executing the cooking function. The following will describe an example of a test procedure for the pressure cooking appliance with reference to fig. 2, in which the pressure cooking appliance is charged with cold water, boiled, pressurized, and depressurized.
Fig. 2 shows a flow chart of a method of testing a pressure cooking appliance according to an embodiment of the present invention. As shown in fig. 2, the pressure cooking appliance may be, for example, an electric pressure cooker, and the flow of the testing method of the pressure cooking appliance may include the following steps:
step S202, judging whether any one of the following three is satisfied: the bottom temperature is lower than a first preset temperature, the internal pressure is lower than a first preset pressure, and the inside of the pot body is in a non-pressure-starting state.
If all the three are satisfied, step S204 is executed, otherwise, step S222 is executed.
Before the pressure cooking appliance is tested, firstly, a proper amount of cold water is added into the pressure cooking appliance, the lid of the pot lid is covered, and then the pressure cooking appliance is electrified. After the test is started, whether the bottom temperature detected by the bottom temperature detection device is lower than a first preset temperature, whether the pressure inside the pot body detected by the pressure detection device is lower than a first preset pressure and whether the inside of the pot body is in a non-pressure-starting state are judged.
The first preset temperature may be set according to actual conditions, and may be the same as the temperature of the added cold water or slightly higher than the temperature of the cold water. At the beginning, the heating device of the pressure cooking appliance is not started, the bottom temperature of the pot body detected by the bottom temperature detection device is similar to the temperature of cold water, if the bottom temperature detected by the temperature detection device is higher than the first preset temperature, the fact that the temperature detection device arranged at the bottom is abnormal is indicated, step S222 is executed, and a prompt related to the test abnormity is sent.
The first preset pressure may be set according to actual conditions, and may be slightly greater than 0, for example. At the beginning, the heating device of the pressure cooking appliance is not started, the internal pressure of the pot body measured by the pressure detection device is almost zero, if the internal pressure of the pot body measured by the pressure detection device is greater than the first preset pressure, the pressure detection device arranged on the upper cover is abnormal, step S222 is executed, and a prompt about the abnormal test is sent.
At the beginning, the heating device of the pressure cooking appliance is not started, the inside of the pot body is in a non-pressure-raising state, if the zero-pressure detection device feeds back that the inside of the pot body is in the pressure-raising state, the zero-pressure detection device is abnormal, step S222 is executed, and a prompt about test abnormity is sent.
If all of the three conditions of step S202 are satisfied, it is indicated that there is no abnormality in the functions of the temperature detecting means provided at the bottom, the pressure detecting means provided at the upper cover, and the zero pressure detecting means in the initial stage, in which case the next test step can be continuously performed.
And step S204, if the three conditions in the step S202 are met, controlling the heating device to be started.
Step S206, after the heating device is controlled to be started, whether the interior of the pot body of the pressure cooking appliance is in a pressure starting state within a first preset time is judged.
The first preset time may be an appropriate value according to the amount of cold water added and the heating power of the heating means.
Under normal conditions, after the heating device is started for a period of time, water in the pot can boil, when the water boils, the zero pressure floater in the zero pressure detection device moves upwards, the zero pressure detection element feeds back a pressure rise signal in the pot body, and the pressure rise state in the pot body can be determined according to the signal. Therefore, if the inside of the pot body is not in the pressure starting state within the first preset time, which indicates that the zero pressure detection device and/or the heating device are abnormal, step S222 is executed to issue a prompt about the test abnormality. Alternatively, step S208 may be executed first, the heating device is controlled to stop heating, and then step S222 is executed.
And if the pressure inside the pot body of the pressure cooking appliance is judged to be in the pressure starting state within the first preset time, indicating that the zero pressure detection device and/or the heating device in the stage are/is in normal function, and continuing to execute the next testing step.
Step S210, judging whether the bottom temperature of the pot body is higher than a second preset temperature and whether the internal pressure of the pot body is higher than a second preset pressure when the inside of the pot body is in a pressure starting state.
When the water in the pot boils, the inside of the pot body is in a pressure-raising state, and the internal pressure of the pot body can also reach the preset pressure. Therefore, whether the temperature detection device and the pressure detection device are abnormal at the moment can be determined according to the bottom temperature of the pot body and the internal pressure of the pot body when the inside of the pot body is in the pressure starting state.
In the embodiment of the invention, the second preset temperature is higher than the first preset temperature, and the second preset pressure is higher than the second preset pressure. The second preset temperature may be the same as the boiling point of water in the pot, or may be slightly less than the boiling point of water, and the second preset pressure may be set accordingly. It will be appreciated that the boiling point of water is different at different atmospheric pressures. If the test of the pressure cooking appliance is performed under the environment of the standard atmospheric pressure, the second preset temperature may be in the range of 90 ° to 100 °, and the second preset pressure may be 55kpa to 65kpa, and preferably may be 60 kpa.
If the bottom temperature is not greater than the second preset temperature and/or the internal pressure is not greater than the second preset pressure when the interior of the pot body is in the pressure starting state, it indicates that the pressure cooking appliance is abnormal, which may be caused by the abnormality of the temperature sensor disposed at the bottom and/or the pressure detection device disposed at the upper cover, in which case step S222 may be executed to issue a prompt about the test abnormality. Alternatively, step S212 may be executed first, the heating device is controlled to stop heating, the voltage reducing device is controlled to work, and then step S222 is executed. The pressure reducing device of the pressure cooking utensil can reduce the pressure through exhaust of an exhaust valve, water cooling, semiconductor refrigeration and the like.
If the bottom temperature is higher than the second preset temperature and the internal pressure is higher than the second preset pressure when the inside of the pot body is in the pressure starting state, the temperature detection device and/or the pressure detection device in the stage are/is normal in function, and the next testing step is continuously executed.
Step S214, if the bottom temperature is higher than the second preset temperature and the internal pressure is higher than the second preset pressure when the inside of the pot body is in the pressure starting state, judging whether the internal pressure is higher than a third preset pressure or not in the heating process of the heating device.
In the embodiment of the invention, the third preset pressure is greater than the second preset pressure. The third preset pressure may preferably be set to 70kpa if the test of the pressure cooking appliance is performed under the environment of the standard atmospheric pressure.
Under the condition that the inside of the pot body is in a pressure starting state, the pressure inside the pot body is continuously increased along with the continuous heating of the heating device. If the internal pressure of the pot body is not greater than the third preset pressure, the detection is continued until the internal pressure of the pot body is detected to be greater than the third preset pressure.
And S216, if the internal pressure is greater than the third preset pressure, controlling the heating device to stop heating, and controlling a pressure reduction device of the pressure cooking appliance to work.
After the internal pressure of the pot body is greater than the third preset pressure, the heating device can be controlled to stop heating, and the pressure reduction device is controlled to work to execute the pressure reduction process.
Step S218, judging whether the interior of the pot body is in a non-pressure starting state within a second preset time.
The second preset time may be set to any suitable value according to specific situations.
Under normal conditions, after the heating device stops heating and the pressure reducing device works for a period of time, the inside of the pot body should be in a non-pressure starting state, and correspondingly, the feedback of the zero pressure detection device should also be a related signal that the inside of the pot body is in the non-pressure starting state.
If the signal fed back by the zero-pressure detection device is still in the pressure starting state within the second preset time after the heating device stops heating and the pressure reduction device starts working, which indicates that one or more of the heating device, the pressure reduction device or the zero-pressure detection device is abnormal, step S222 is executed, and a prompt about the test abnormality is sent.
And S220, if the interior of the pot body is in a non-pressure-starting state within the second preset time, sending a prompt about normal test.
In the embodiment of the invention, the prompt about normal test or abnormal test can be displayed through the display screen of the pressure cooking appliance, and when observing the prompt about normal test, a worker can determine that each function of the tested pressure cooking appliance is normal. When observing the prompt about the test abnormality, the worker can determine that the tested pressure cooking appliance is abnormal in function, and in this case, the worker can further test the tested pressure cooking appliance to determine the abnormal component.
Steps S202 to S222 describe an overall flowchart for testing the pressure cooking appliance, and during the actual testing process, a part of the flowchart may be executed to determine whether each function of the pressure cooking appliance is normal at different stages of the pressure cooking appliance according to requirements.
