Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As before, in the use process of the refrigeration equipment, water vapor suddenly cools in a refrigeration chamber and is condensed into frost, if the water vapor is not processed in time, a thick layer of ice is formed, the refrigeration capacity and the preservation capacity are affected, and the power consumption of the refrigeration equipment is increased.
At present, a defrosting method of refrigeration equipment mainly comprises the following steps: and (3) starting the defrosting mode by presetting the defrosting time, and closing the defrosting mode when the preset defrosting time is reached. However, this solution does not allow an accurate determination of whether the device has finished defrosting. If the set time is too long, the compressor stops after the defrosting mode is entered, the defrosting heater is electrified to work, the temperature in the refrigeration equipment is increased, and the defrosting time is too long, so that the temperature rise of the freezing chamber is too high, the food material fresh-keeping is affected, and the power consumption is increased; and if the defrosting time is too short, incomplete defrosting is easily caused, and the refrigeration efficiency is influenced. Therefore, it is important to accurately determine the defrosting mode exit condition in time.
Based on this, the scheme considers that whether the current refrigeration equipment container defrosting is finished or not is further judged according to the weight of the defrosting water by collecting the weight of the water generated by defrosting, and then whether the defrosting mode is exited or not is determined. Whether the defrosting is finished or not can be accurately determined, the fresh-keeping and the power consumption increase of objects cannot be influenced due to the overlong defrosting time, and the insufficient defrosting of the refrigeration equipment cannot be realized due to the overlong defrosting time.
The defrosting method and apparatus provided by the present invention will be described in further detail below.
As shown in fig. 1, an embodiment of the present invention provides a defrosting method, which may include the following steps:
step 101: collecting the weight of defrosting water in a water storage box according to a preset time interval; the water storage box is used for receiving water generated by the refrigeration equipment during defrosting;
step 102: determining the execution state of defrosting in the refrigeration equipment according to the weight of defrosting water;
step 103: when the execution state is defrosting completion, controlling the refrigeration equipment to exit a defrosting mode; and when the execution state is that defrosting is not finished, controlling the refrigeration equipment to be continuously in a defrosting mode.
In the embodiment of the invention, after the defrosting mode is started, the weight of defrosting water in the water storage box is collected according to the preset time interval, and then the defrosting execution state in the refrigeration equipment is determined according to the weight of the defrosting water, so that when the defrosting execution state is determined to be the defrosting completion state, the refrigeration equipment can be controlled to exit the defrosting mode, otherwise, the refrigeration equipment is continuously in the defrosting mode. Therefore, the weight of the water generated during defrosting is analyzed, whether defrosting is completed or not can be judged, and whether the defrosting mode needs to be quitted or not is determined, so that the defrosting in the refrigeration equipment can be thoroughly guaranteed, the defrosting mode can be timely quitted after defrosting is completed, the fresh-keeping of the internal materials of the equipment is prevented from being influenced due to overhigh temperature rise in the refrigeration equipment, and the power consumption is increased.
The scheme considers that the water storage box is placed in the refrigeration equipment, for example, the water storage box is arranged at the bottom of the refrigeration equipment. When defrosting, the frost layer on the evaporator is gradually melted and flows into the water storage box. Whether defrosting is finished or not can be judged by detecting the weight of the water storage box.
To gathering the weight of the defrosting water in the water storage box, can be through installing gravity sensor on the water storage box to gather through gravity sensor defrosting water weight. When the weight is collected, the time interval of response can be set according to different application equipment and application scenes. For defrosting of a refrigerator, for example, the time interval may be set to 15s, that is, the weight of the defrosting water in the water storage box is collected every 15 s.
Step 102 may consider setting a weight threshold when determining the execution state of defrosting in the refrigeration apparatus according to the weight of the defrosting water. For example, in some application scenarios, when the weight of the defrosting water reaches 400g, the defrosting can be considered to be completed, and then the weight threshold can be set to 400 g. By comparing the weight of the collected defrosting water with 400, when the weight of the collected defrosting water is larger than 400, the refrigeration equipment is considered to be defrosted completely, the defrosting mode can be exited, and otherwise, the refrigeration equipment is continuously in the defrosting mode.
Of course, in another possible implementation manner, the step 102 may also be implemented by the following manner when determining the defrosting execution state in the refrigeration equipment according to the weight of the defrosting water:
aiming at the weight of the defrosting water collected every time, the following steps are carried out:
calculating the difference value between the weight of the currently collected defrosting water and the weight of the defrosting water collected at the previous time;
and determining the defrosting execution state in the refrigeration equipment according to the difference value and a preset first weight difference threshold value.
In this embodiment, it is considered that, when the weight of the defrosting water is collected each time, a difference between the collected weight of the defrosting water and the previous collected weight of the defrosting water is calculated, and whether defrosting in the current refrigeration equipment is completed or not can be determined by comparing the difference with the set first weight difference threshold.
Of course, in the case of collecting the weight of the defrosting water for the first time, the weight of the defrosting water collected for the previous time may be defaulted to 0 g.
In a possible implementation manner, when determining the execution state of defrosting in the refrigeration equipment according to the difference value and a preset first weight difference threshold, the implementation manner may be specifically implemented as follows:
determining the magnitude relation between the difference value and a preset first weight difference threshold value;
if the difference value is larger than the first weight difference threshold value, determining that the defrosting execution state in the refrigeration equipment is that defrosting is not finished;
and if the difference value is smaller than the first weight difference threshold value, determining that the defrosting execution state in the refrigeration equipment is defrosting completion.
For example, the weight of the currently collected defrosting water is 500g, the weight of the previously collected defrosting water is 400g, and the first weight difference threshold is 20g, it is obvious that the difference value between the current weight of the defrosting water and the previous weight of the defrosting water is greater than the first weight difference threshold, it can be determined that defrosting inside the refrigeration equipment is not completed, and therefore the defrosting mode should be continuously executed to ensure thorough defrosting inside the refrigeration equipment; for another example, the weight of the currently collected defrosting water is 500g, the weight of the previously collected defrosting water is 485g, and the first weight difference threshold is 20g, it is obvious that the difference between the weight of the currently collected defrosting water and the weight of the previously collected defrosting water is smaller than the first weight difference threshold, so that it can be determined that defrosting inside the refrigeration equipment is completed, and thus the defrosting mode can be exited, and the influence on the freshness preservation of the materials inside the equipment due to the overhigh temperature rise inside the refrigeration equipment and the increase in power consumption caused by the overhigh temperature rise inside the refrigeration equipment are avoided.
In another possible implementation manner, when determining the defrosting execution state in the refrigeration equipment according to the difference value and the preset first weight difference threshold, the defrosting execution state in the refrigeration equipment can be further implemented by the following manner:
determining the magnitude relation between the difference value and a preset first weight difference threshold value;
if the difference values obtained after the weight of the defrosting water is continuously collected for N times are smaller than the first weight difference threshold value, determining that the defrosting execution state in the refrigeration equipment is defrosting completion;
otherwise, determining that the defrosting execution state in the refrigeration equipment is incomplete.
In order to further improve the accuracy of determining whether defrosting is completed, in this embodiment, a size relationship between the determination difference and the first weight difference threshold is considered, and if the difference obtained after the weights of defrosting water are collected for multiple times continuously is smaller than the first weight difference threshold, it may be determined that defrosting in the refrigeration equipment is completed, otherwise, defrosting is not completed. Therefore, after the defrosting water intermediate quantity is continuously collected for multiple times, whether the difference value is smaller than the first weight difference threshold value or not can be judged, the condition that the execution state is judged by mistake due to the fact that defrosting efficiency of a defrosting water weight collecting device for two times is not high can be avoided, and therefore the accuracy of judging whether defrosting is finished or not can be further improved.
For example, when N is 5, 4 sets of difference values obtained after continuously collecting the weights of the defrosting water for 5 times are respectively 100g, 50g, 50g and 60g, and the first weight difference threshold value is 20g, and obviously, if the 4 sets of difference values are greater than the first weight difference threshold value, it is determined that defrosting is not completed. For another example, when N is 5, 4 groups of difference values obtained after continuously collecting the weights of the defrosting water for 5 times are respectively 11g, 10g, 5g and 3g, and the first weight difference threshold value is 20g, and obviously, the 4 groups of difference values are all smaller than the first weight difference threshold value, and it is determined that defrosting is completed.
In one possible implementation, the water storage cartridge may be full of water due to defrosting, thus allowing for a reminder to be given to the user when the defrosting water reaches a certain weight. For example, after the refrigeration device is controlled to exit the defrosting mode, the following method may be specifically implemented:
collecting the weight of defrosting water in a water storage box;
judging whether the weight of the defrosting water reaches a preset second weight threshold value or not;
if the weight of the defrosting water reaches a second weight threshold value, sending alarm information;
in this embodiment, after the refrigeration equipment exits the defrosting mode, the weight of the water storage box is collected again, then the magnitude relation between the weight and the preset second weight threshold is judged, and if the weight of the defrosting water reaches the second weight threshold, it indicates that the water storage box is full or is about to be full, so that the user is reminded to clean the defrosting water in the water storage box in time by sending alarm information.
Of course, it is also contemplated to place a high pressure tube in the water storage compartment of a refrigeration device such as a refrigerator or merchandiser. Used for evaporating the defrosting water collected by the water storage box. For example, after the alarm message is sent, the high-pressure pipe is automatically started to evaporate the defrosting water in the water storage box.
In a possible implementation manner, when the execution state is that defrosting is not completed, before controlling the refrigeration equipment to continue to be in the defrosting mode, the method further includes:
collecting the weight of defrosting water in a water storage box;
judging whether the weight of the defrosting water reaches a preset second weight threshold value or not;
if the weight of the defrosting water reaches a second weight threshold value, sending alarm information and exiting the defrosting mode; and the number of the first and second groups,
and according to a preset time interval, acquiring the weight of the defrosting water, judging whether the weight reaches a second weight threshold value, stopping sending alarm information until the weight of the defrosting water is smaller than the second weight threshold value, and restarting a defrosting mode.
In this embodiment, when the defrosting mode is in, it is also determined whether the weight of the defrosting water in the water storage box reaches the threshold, and if the weight of the defrosting water in the water storage box reaches the threshold, an alarm message is sent out, and the defrosting mode is exited. And then continuously collecting the weight of the defrosting water according to a preset time interval, and judging the relation between the weight of the defrosting water and a second weight threshold value to determine whether the defrosting water in the water storage box is cleaned. And when the defrosting water is determined to be cleaned, stopping sending the alarm information, and restarting the defrosting mode again. Therefore, the refrigeration equipment is prevented from overflowing to the refrigeration equipment due to the fact that the water storage box is full in the defrosting process.
