Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiment is not intended to limit the present invention, and structural, methodological, or functional modifications of the invention according to the embodiment are included in the scope of the invention.
Referring to fig. 1, the refrigerator 100 provided by the invention comprises a box body 101, a door body 102 and a weighing sensor 103 arranged on the box 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 keys; the load cell 102 may also be communicatively coupled to a control system of the refrigerator 100 and store relevant data via the control system.
The case 101 is formed with a storage compartment opened forward; the door 102 is used for opening or closing the storage compartment; the load cell 103 may be generally disposed proximate to the bottom wall of the storage compartment. The load cell 103 may cause abnormal operation of the load cell 103 due to extrusion, impact or foreign matter intrusion; 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, where the components may cause abnormal use of the weighing sensor 103 once they interfere with the weighing sensor 103 during use.
In order to realize the working state test of the weighing sensor 103, improve the weighing accuracy and avoid the abnormal weighing, 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 a calibration weight M of the weighing sensor 103;
comparing the calibration weight M with the calibration weight M0;
if N1 is less than or equal to M-M0 is less than or equal to N2, judging that the weighing sensor 103 works normally, and replacing the calibration weight M0 with the calibration weight M;
if M-M0 is less than N1 or M-M0 is more than N2, the load cell 103 is judged to be abnormal.
The calibration detection can be performed on the weighing sensor 103 during the operation of the refrigerator 100 by the above method, wherein the calibration weight M refers to the 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 is data stored in a register of the load cell 103 or a control system of the refrigerator 100 and used for comparing with the calibration weight M; n1 and N2 are thresholds for determining M-M0, and obviously N1 < N2 and N1 is a negative value.
Here, when the difference between the calibration weight M and the calibration weight M0 is between N1 and N2, it is determined that the load cell 103 is operating normally, and the calibration weight M0 is replaced by 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 storing the calibration weight M as a new calibration weight M0 and deleting the original calibration weight M0. When the load cell 103 performs calibration detection, the corresponding calibration weight M0 is the calibration weight M when the load cell 103 performs the last calibration detection and determines that the operation is normal. By the design, the deviation of the weighing sensor 103 caused by abrasion and the like during long-time use is avoided.
The test method further includes analyzing the error type and transmitting error information when it is determined that the load cell 103 is abnormal. Specifically, the "resolving error type" includes generating an error code according to the detection result of the load cell 103; and comparing the error code with pre-stored data to determine the error type.
The step of sending error information is to send 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 first error information;
if M-M0 > N2, sending out a second error message, wherein the first error message generally refers to structural interference causing other supporting forces of the weighing sensor 103; conversely, the second error message generally means that the load cell 103 is subjected to other pressures. The error information may be conveyed to the user in particular by means of sound, text or images, etc.
In another embodiment of the invention, which is distinguished from the previous example, as shown in fig. 3, is characterized in that: the test method further comprises the step of detecting the weight M1 of the first balancing weight by adopting the weighing sensor 103 when the calibration weight M is not less than N1 and not more than M0 and not more than N2;
if N3 is less than or equal to M1 and less than or equal to N4, judging that the weighing sensor 103 works normally, and replacing the calibration weight M0 with the calibration weight M;
if M1 is less than N3 or M1 is more than N4, the load cell 103 is judged to be abnormal.
The first balancing weight has a predetermined weight, N3 and N4 are thresholds corresponding to the first balancing weight, and the essence of "N3 is less than or equal to M1 is less than or equal to N4" means that the actual weight M1 of the first balancing weight detected by the weighing sensor 103 meets a predetermined error requirement. It is further checked by the above-mentioned test procedure whether the load cell 103 is functioning properly.
Similarly, the test method further includes parsing the error type and transmitting an error message when it is determined that the load cell 103 is abnormal. The step of sending error information specifically includes:
if M-M0 is less than N1 or M1 is less than N3, sending out first error information;
if M-M0 > N2 or M1 > N4, a second error message is sent.
Considering the calibration weight M0 used when the first calibration detection is performed after the shipment of the load cell 103, the predetermined data M0 of the load cell 103 of the corresponding model may be used. The calibration weight M0 may be obtained by initially detecting the weight sensor 103 before the refrigerator 100 leaves the factory.
Referring to fig. 4, the initial detection process includes:
charging working current to the assembled weighing sensor 103;
detecting and acquiring the initial weight m of the load cell 103;
comparing the initial weight m with the set data m0;
if n1 is less than or equal to M-M0 is less than or equal to n2, judging that the weighing sensor 103 is assembled normally, and storing the initial weight M as a calibration weight M0;
if m-m0 < n1 or m-m0 > n2, the abnormal assembly of the load cell 103 is judged.
Here, the predetermined data M0 of the weighing sensor 103 with the corresponding model may be regarded as the calibration weight M0 in the initial detection process; n1 and n2 are thresholds set correspondingly. That is, after the completion of the assembly of the load cell 103, the initial power-on detection is performed to determine whether the load cell 103 is assembled normally. Similarly, the testing method further comprises the step of sending corresponding error information to field personnel when the weighing sensor 103 is judged to have abnormal assembly, so that rapid investigation is facilitated, and assembly adjustment is performed.
The initial detection process may further use a second balancing weight to perform further detection and verification on whether the weighing sensor 103 is assembled normally, and specifically includes:
when the initial weight M is not less than n1 and not more than M-M0 and not more than n2, detecting the weight M2 of the second balancing weight by adopting the weighing sensor 103;
if n3 is not less than M2 and not more than n4, judging that the weighing sensor 103 is assembled normally, and storing the initial weight M as a calibration weight M0;
if M2 is less than n3 or M2 is more than n4, the abnormal assembly of the load cell 103 is judged.
The second balancing weight and the first balancing weight can be set to be the same or different, and n3 and n4 are weight thresholds corresponding to the second balancing weight.
In the practical application process of the refrigerator 100, the testing method further includes prompting the user to calibrate and detect the weighing sensor 103 every predetermined time interval, so as to ensure the weighing precision.
In summary, with the refrigerator 100 and the testing method thereof according to the present invention, a user can conveniently detect and calibrate the weighing sensor 103 by calibrating the weight M0, thereby ensuring the accuracy of weighing food materials, and also can timely find out the possible abnormal working condition of the weighing sensor 103, so as to perform maintenance processing and improve user experience.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
