[0002] The liquid level switch and the water pump are mainly applied to the models of air conditioners that need to discharge condensed water. The liquid level switch mainly monitors the water level inside the air conditioner through the position of the float. After reaching the designed water level, it feeds back a signal to the controller for relevant command operations. The water pump mainly pumps water according to some commands of the controller.

[0003] For the detection method of the water pump, it mostly adopts power-on and idling, and it is impossible to realize the on-off verification in the use environment and the related medium load experiment.

[0037] (1) Start the control box 1 and check whether the control box 1 starts normally. If so, the indicator light is always on, otherwise it is off; (2) Set the total number of tests;

[0038] (3) The water pump in the second water tank 62 is started, while the water pump in the first water tank 61 is turned off. Check whether the water pump can work properly.

[0042] A computer-readable storage medium stores a computer program. When the computer program is executed, it can implement the above-mentioned combined test method for a liquid level switch and a water pump for an air conditioner.

[0043] Example:

[0044] The test component is divided into two areas, namely the first water tank 61 and the second water tank 62. The two containers are independent and not connected, and the two containers have the same volume, which is convenient for controlling the on-off time of the water pump. There are multiple water pump fixing frames 65 and liquid level switch fixing frames in the two containers. The fixing frames adopt a non-destructive installation method. The medium between the two containers is water that is pollution-free and non-corrosive, and the medium between the two containers is transported through the water pipes connecting the water pumps.

[0045] In the test component part of the test device, the water pumps in the medium-driven water pumps synchronously arrange the test samples (test objects), and the reliability tests of two components (water pumps and liquid level switches) can be completed at one time, with high test efficiency and reduced test costs.

[0046] The entire test device is powered by a 220V power supply. The internal components work under this power supply. The front panel part consists of two timers 2, six dual-channel counters 3, a power switch, and an indicator light. Above is the docking pin socket, which forms two water pump docking pin sockets 4 and twelve liquid level switch dockings.

[0047] The timer 2 mainly controls the pumping working time of the medium driving device through timing, so as to control the liquid level heights of the water in the first water tank 61 and the second water tank 62. That is, when the liquid level height in the first water tank 61 reaches the action point of the liquid level switch therein, the test water pump in the first water tank 61 stops pumping water, and the test water pump in the second water tank 62 starts pumping water until the liquid level height in the second water tank 62 reaches the action point of the liquid level switch therein. This cycle is repeated to realize the repeated on-off test of the water pump and the liquid level switch, so as to achieve the purpose of the reliability test.

[0048] The counter 3 mainly records the on-off test data of the liquid level switch, and stops recording data in the case of abnormal conduction of the liquid level switch, so as to achieve the purpose of collecting reliability data. At the same time, for the samples with specified test times in the test, the relevant test times can be controlled.

[0049] The power switch controls the on-off of the power supply of the entire test system to achieve free on-off control and ensure the safety of the experiment. The indicator lamp monitors the power-on of the test system and whether the system is normal. It is normally open in the case of normal power-on and goes out in the case of abnormality to monitor the working state of the system. The docking pin base mainly docks the water pump and the liquid level switch to be tested of the test component to achieve non-destructive docking.

[0050] In summary, after reading the documents of the present invention, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present invention, and all of them fall within the scope protected by the present invention.
