Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. The present invention is not limited to the embodiment, and structural, methodological, or functional changes made by one of ordinary skill in the art according to the embodiment are included in the scope of the present invention.
Referring to fig. 1, a refrigerator 100 provided by the present invention includes a refrigerator body 101, a door body 102, and a load cell 103 disposed on the refrigerator body 101 or the door body 102.
The weighing sensor 102 can be used as an independent module for weighing, and the weighing sensor 103 can be provided with a corresponding register, an operation interface or a key; the load cell 102 may also be communicatively coupled to a control system of the refrigerator 100 and store pertinent data via the control system.
The box body 101 is provided with a storage compartment which is opened forwards; the door 102 is used for opening or closing the storage compartment; the load cell 103 may be generally disposed proximate a bottom wall of the storage compartment. The load cell 103 may be abnormally operated due to extrusion, impact or intrusion of foreign matter into the load cell 103; the refrigerator 100 may further include a shelf and a drawer for holding food materials, and the weighing sensor 103 may also be provided with a tray for holding food materials to be weighed, which may also cause abnormal use of the weighing sensor 103 once the components interfere with the weighing sensor 103 in the use process.
In order to realize the working state test of the weighing sensor 103, improve weighing accuracy and avoid weighing abnormity, the application provides a test method of the refrigerator 100.
Referring to fig. 2, the method for testing the refrigerator 100 includes:
detecting and acquiring the calibration weight M of the weighing sensor 103;
comparing the calibration weight M to a calibration weight M0;
if the N1 is not less than M-M0 is not less than N2, judging that the weighing sensor 103 works normally, and replacing the calibrated weight M0 with a calibrated weight M;
and if the M-M0 is less than N1 or the M-M0 is more than N2, judging that the weighing sensor 103 is abnormal.
By the method, the weighing sensor 103 can be calibrated and detected in the operation process of the refrigerator 100, wherein the calibration weight M refers to a detection result when no article is placed on the weighing sensor 103, and can be understood as the gross weight of the weighing sensor 103; the calibration weight M0 refers to data stored in a register of the load cell 103 or in a control system of the refrigerator 100 and used for comparison with the calibration weight M; n1 and N2 are thresholds for judging M-M0, and obviously, N1 < N2 and N1 are negative values.
Here, when the difference between the calibration weight M and the calibration weight M0 is between N1 and N2, the load cell 103 is judged to be functioning properly, and the calibration weight M0 is replaced with the calibration weight M. In other words, the calibration weight M0 is not a constant value, and the "replacing the calibration weight M0 with the calibration weight M" means that the calibration weight M is stored as a new calibration weight M0, and the original calibration weight M0 is deleted. When the weighing sensor 103 performs calibration detection, the corresponding calibration weight M0 is the calibration weight M when the weighing sensor 103 performs the last calibration detection and determines that the work is normal. Through the design, the deviation of the weighing sensor 103 caused by abrasion and the like in the long-time use process is avoided.
The testing method further comprises the steps of analyzing the error type and sending error information when the weighing sensor 103 is judged to be abnormal. Specifically, the "resolving the error type" includes generating an error code from the detection result of the load cell 103; and comparing the error codes with prestored data to determine the error type.
The step of sending error information refers to sending out error information matched with the error type, wherein the error information comprises first error information and second error information;
if M-M0 is less than N1, sending out a first error message;
if M-M0 is greater than N2, a second error message is sent, wherein the first error message is usually that structural interference causes other supporting force to appear on the weighing sensor 103; in contrast, the second error message generally means that the load cell 103 is subjected to another pressure. The error information may be specifically conveyed to the user by means of sound, text, or image.
Referring to fig. 3, in another embodiment of the present invention, it is characterized by the following features in the previous embodiment: the test method further comprises detecting a weight M1 of a first counterweight block by using the load cell 103 when the calibration weight M satisfies N1 ≦ M-M0 ≦ N2;
if the weight M1 is not less than N3 and not more than N4, judging that the weighing sensor 103 works normally, and replacing the calibrated weight M0 with a calibrated weight M;
and if M1 is less than N3 or M1 is more than N4, judging that the load cell 103 is abnormal.
The first weight block has a predetermined weight, N3 and N4 are thresholds corresponding to the first weight block, and the fact that the actual weight M1 of the first weight block detected by the load cell 103 meets a predetermined error requirement is substantially indicated by the fact that "N3 is not less than M1 is not less than N4". Whether the weighing sensor 103 works normally is further detected through the test steps.
Similarly, the test method further comprises the steps of resolving the error type and sending error information when the weighing sensor 103 is judged to be abnormal. The step of sending error information specifically comprises the following steps:
if M-M0 < N1 or M1 < N3, sending a first error message;
if M-M0 > N2 or M1 > N4, a second error message is issued.
Considering the calibration weight M0 used in the first calibration detection after the load cell 103 leaves the factory, the set data M0 of the load cell 103 of the corresponding model may be used. The weighing sensor 103 may perform initial detection before the refrigerator 100 leaves the factory, and obtain the calibration weight M0.
Referring to fig. 4, the initial detection process includes:
working current is introduced into the assembled weighing sensor 103;
detecting and acquiring the initial weight m of the weighing sensor 103;
comparing the initial weight m with the established data m 0;
if n1 is not less than M-M0 is not less than n2, judging that the assembly of the weighing sensor 103 is normal, and storing the initial weight M as a calibrated weight M0;
and if m-m0 is less than n1 or m-m0 is more than n2, judging that the assembly of the weighing sensor 103 is abnormal.
Here, the set data M0 of the load cell 103 of the corresponding model can also be regarded as the calibration weight M0 in the initial detection process; n1 and n2 are correspondingly set thresholds. That is, after the assembly of the load cell 103 is completed, the initial power-on detection is performed to determine whether the assembly of the load cell 103 is normal. Similarly, the test method further comprises the step of sending corresponding error information to field personnel when the weighing sensor 103 is judged to be abnormally assembled, so that quick troubleshooting and assembly adjustment can be conveniently carried out.
The initial detection process may further adopt whether the second counterweight symmetric retransmission sensor 103 is normally assembled for further detection and verification, specifically including:
when the initial weight M meets the condition that n1 is not less than M-M0 is not less than n2, detecting the weight M2 of the second balancing weight by using the weighing sensor 103;
if the n3 is not less than M2 is not less than n4, judging that the assembly of the weighing sensor 103 is normal, and storing the initial weight M as the calibrated weight M0;
and if M2 is less than n3 or M2 is more than n4, judging that the assembly of the load cell 103 is abnormal.
The second balancing weight and the first balancing weight can be arranged to be the same or different, and n3 and n4 are weight thresholds corresponding to the second balancing weight.
In the actual application process of the refrigerator 100, the test method further includes prompting a user to perform calibration and detection of the weighing sensor 103 every predetermined time interval, so as to ensure weighing accuracy.
In summary, with the refrigerator 100 and the testing method thereof of the present invention, a user can conveniently perform detection and calibration on the weighing sensor 103 through the calibration weight M0, so as to ensure accuracy of weighing food materials, and also can timely find out possible abnormal working conditions of the weighing sensor 103, so as to perform maintenance processing, and improve user experience.
