All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and are not of specific significance per se. Thus, "module" and "component" may be used in combination.
Refrigerators, which are a kind of refrigerating apparatus for maintaining a constant low temperature, and also a kind of products for maintaining foods or other articles in a constant low temperature cold state, have been introduced into home households, becoming one of indispensable components of home appliances. In the using process of the refrigerator, when people store food and open the refrigerator, indoor air and air in the refrigerator are freely exchanged, moisture in the cleaned food such as vegetables and fruits is evaporated, and the food can be condensed into frost after being cooled and is frozen on the inner wall of the refrigerator, so that the refrigerator is often required to be defrosted. When defrosting, all foods in the refrigerator in a preservation state need to be temporarily emptied, and defrosting is accelerated by hot water or a blower, so that part of the foods in the refrigerator are easy to melt or deteriorate, and the time is long.
In order to solve the problems mentioned in the background art, according to an aspect of an embodiment of the present application, there is provided a defrosting method of a refrigerator, as shown in fig. 1, including:
Step 101, detecting a storage state of a containing compartment of a refrigerator, wherein the refrigerator comprises a plurality of mutually independent containing compartments, and a heater is arranged in each containing compartment;
step 103, under the condition that the storage state is detected to be converted from the placement state to the empty state, acquiring first frosting data of the accommodating compartment;
Step 105, generating a defrosting strategy corresponding to the first frosting data;
Step 107, controlling the heater according to the defrosting strategy to defrost the receiving compartment.
The application is applied to the field of intelligent home, in particular to defrosting of a refrigerator.
The frosting of the refrigerator can reduce the refrigerating efficiency of the refrigerator, not only can the food preservation be influenced, but also the operation of an air conditioner can be influenced.
When the refrigerator is determined to be required to defrost, all foods are required to be taken out for defrosting, so that the food preservation can be influenced, and the whole operation flow is troublesome. The refrigerator provided by the application is provided with a plurality of containing compartments, and each containing compartment is internally provided with the heater, so that the frosting state of the containing compartment can be detected after food is taken out, and then a defrosting strategy is further determined when frosting exists, so that each containing compartment without food is independently defrosted, and therefore, the defrosting can be performed in time, and the preservation of normal food is not influenced.
Under the condition that the storage state is detected to be converted from the placement state to the empty state, the first frosting data of the accommodating compartment can be immediately acquired, and the first frosting data can be acquired at intervals of a preset time length. Because after the food is taken out, if moisture remains, frosting may still occur.
Optionally, in the case that the storage state is detected to be converted from the placement state to the empty state, whether residual moisture exists in the accommodating compartment or not may be detected, and if the residual moisture exists, the moisture is removed by using the dehumidifying device, so that frosting and even icing are avoided.
As an alternative embodiment, generating the defrost policy corresponding to the first frosting data comprises: acquiring frosting thickness and frosting area from the first frosting data; determining the heating time length and the heating temperature of the heater by utilizing the frosting thickness and the frosting area; the strategy of controlling the heater to heat the receiving compartment at the heating temperature for the heating period is determined as a defrost strategy.
In general, the heating time is proportional to the frost thickness and the frost area, and the heating temperature is proportional to the frost thickness and the frost area.
Specifically, the heating time length and the heating temperature corresponding to each frosting thickness are different, the heating time length and the heating temperature corresponding to each frosting area are also different, and the heating time length and the heating temperature corresponding to the combination of different frosting thicknesses and frosting areas are also different, so that the heating time length and the heating temperature corresponding to the three conditions can be determined through experiments in advance, namely, the defrosting strategy is determined. For example, conventional defrost strategies and flash defrost strategies, which have the same frost formation thickness and/or frost formation area, may be heated for a shorter period of time than the flash defrost strategy, and/or may be heated at a lower temperature than the flash defrost strategy.
The defrost strategy obtained through the test can be very varied and is not limited to the examples of the present application.
Alternatively, the heater may be replaced by a valve connected to the cool air output passage and the hot air discharge passage of the compressor, and the valve may be switched between three states of opening the cool air output passage, opening the hot air discharge passage, and closing all the same, so as to regulate the temperature of the accommodating compartment.
As an alternative embodiment, a dehumidifying apparatus is provided in each of the accommodating compartments in the refrigerator, and controlling the heater according to a defrost strategy to defrost the accommodating compartment includes: setting the use state of the accommodating compartment to be an unavailable state, and controlling the heater to heat the accommodating compartment according to the heating temperature; removing moisture left in the accommodating compartment after defrosting by using a dehumidifying device after the heater is turned on for a heating period; acquiring second frosting data of the dehumidified accommodating compartment; and under the condition that the second frosting data determines that the containing compartment does not have frosting, converting the using state of the containing compartment into an available state so as to prompt the target object to complete defrosting of the containing compartment.
The setting of the usage status of the accommodating compartment to the unavailable status is to prompt the user that the accommodating compartment needs to be defrosted, and the usage status of the accommodating compartment may be indicated by the color of the indicator light on the accommodating compartment, for example, the indicator light is green to indicate that the accommodating compartment is in the available status, and the indicator light is red to indicate that the accommodating compartment is in the unavailable status.
After defrosting, moisture may remain, so we need to remove the moisture in the compartment with a dehumidifying device, and then further determine whether the compartment is frosted.
Under the condition that the second frosting data determines that the containing compartment is not frosted, the defrosting is determined to be completed, and the using state of the containing compartment is converted into an available state so as to prompt a user that the containing compartment is in a frostless state, and the device can be normally used.
Optionally, the bottom of the accommodating compartment may be set to be in an inclined state, and the bottommost end is provided with a plurality of openings so that water can flow out by itself.
As an alternative embodiment, the method further comprises moving the plurality of accommodation compartments to the same target area in case it is detected that the storage states of the plurality of accommodation compartments are simultaneously changed from the set state to the empty state; acquiring third frosting data of a plurality of accommodating compartments in the target area; generating a target defrosting strategy by using the third frosting data; defrosting the plurality of containment compartments in the target area according to the target defrost strategy.
For example, a plurality of accommodating compartments requiring defrosting may be determined first, and then the accommodating compartments are moved to a target area to perform collective heat supply for defrosting.
Specifically, the method for generating the target defrosting policy by using the third frosting data is similar to the method for generating the defrosting policy corresponding to the first frosting data, and will not be described herein.
The heater is then controlled to defrost the plurality of receiving compartments in the target area in accordance with the target defrost strategy.
The collective defrosting can uniformly control the heaters of all the accommodating compartments needing defrosting, and the defrosting strategy is not required to be independently generated for each accommodating compartment, so that the energy consumption caused by defrosting can be reduced.
As an alternative embodiment, detecting a storage state of a receiving compartment of a refrigerator includes: detecting the placement weight of the accommodating compartment; under the condition that the placing weight is detected to be reduced from large to small, collecting point cloud data of the accommodating compartment; determining a current volume of the containment compartment using the point cloud data; and under the condition that the current volume is equal to the target volume, determining that the accommodating compartment is converted from the accommodating state to the empty state, wherein the target volume is the volume when the accommodating compartment is not frosted and is in the empty state.
Optionally, the pressure sensor detects the placing weight of the accommodating compartment, and when the placing weight is detected to be changed from large to small, it can be determined that food is taken out by the user, then it can be further determined whether the food in the accommodating compartment is taken out completely according to the point cloud data in the compartment, if all the food is taken out, the accommodating compartment is determined to be converted from the placing state to the empty state, and if not taken out completely, the accommodating compartment is determined to be still in the placing state.
Optionally, the millimeter wave radar is used to collect point cloud data of the accommodating compartment, the millimeter wave radar can be arranged on a panel of the accommodating compartment which can be opened and closed, and the accommodating compartment is separated from the accommodating compartment by a heat insulation board, so that four faces of the accommodating compartment, namely, an upper face, a lower face, a left face and a right face, are compartment planes (namely, the heat insulation board), a moving track can be arranged behind the accommodating compartment for moving the accommodating compartment, a switch panel is arranged in front of the accommodating compartment, and a user can directly open or close the switch panel to take and put food.
In particular, it is common to determine the current volume of the compartment using point cloud data, and the technical solution of calculating the volume of space from the point cloud data is not particularly limited here.
Since if frost is present, the frost necessarily interferes with the acquired point cloud data, affecting the current volume calculated from the point cloud data, it may be determined that the current compartment is not holding any food and is not frosted if the current volume is equal to the target volume.
Then in case the current volume is smaller than the target volume it should be further determined whether the occupied volume is food or frost, as will be explained below.
As an alternative embodiment, after determining the current volume of the receiving compartment, the method further comprises: determining a volume difference between the current volume and the target volume when the current volume is smaller than the target volume; under the condition that the volume difference value is smaller than or equal to a preset volume threshold value, utilizing a preset identification model to identify whether the point cloud data comprises frost layer data or not; if the point cloud data comprises frost data, judging that food is not stored in the accommodating compartment, and determining that the accommodating compartment is converted from the placing state to the empty state.
Specifically, if the current volume is much smaller than the target volume, it can be directly determined that the occupied volume is food, so a preset volume threshold needs to be set to determine whether the cloud data further includes frost layer data, the preset volume threshold is set according to the target volume of the accommodating compartment, for example, one fiftieth of the target volume, and the application is not limited to specific values.
In the embodiment provided by the application, the frost layer data in the point cloud data are identified through a preset identification model, and the method comprises the following steps: clustering the acquired point cloud data to obtain point cloud data with depth characteristics; and inputting the point cloud data with the depth characteristics into a preset identification model, and outputting the point cloud category of the point cloud data through the preset identification model.
If the point cloud class output by the preset identification model comprises frost layer point clouds, the situation that the accommodating compartment is frosted can be determined.
The application further provides a method for training the neural network model to obtain the preset recognition model, which is described below.
As an alternative embodiment, the method further comprises training a preset recognition model in the following way: acquiring target point cloud data of a containing compartment, and training an initial model by taking the target point cloud data as a training set to output a point cloud class of the target point cloud data through the initial model, wherein the target point cloud data comprises frost layer point cloud data and compartment plane point cloud data, the frost layer point cloud data carries class labels of the frost layer point cloud, and the compartment plane point cloud data carries class labels of the compartment Ping Miandian cloud; comparing the point cloud type output by the initial model with the type label carried by the target point cloud data to obtain a comparison result; and determining the initial model as a preset recognition model under the condition that the comparison result indicates that the recognition accuracy of the initial model is greater than or equal to the accuracy threshold.
The foregoing description of the method for collecting point cloud data has been described, and will not be repeated here. The target point cloud data herein is different from the above point cloud data in that: the target point cloud data are marked point cloud data, and the marked content is carried type labels.
The method comprises the steps of identifying the category of target point cloud data by training an initial model, comparing the identified category with category labels carried by the target point cloud data, and determining the probability of the category labels in an identification result, so that the identification accuracy of the initial model is determined.
Optionally, the accuracy threshold is any value approaching 100%, and may be set according to practical situations.
And under the condition that the comparison result indicates that the recognition accuracy of the initial model is smaller than the accuracy threshold, adjusting parameters of the initial model, and continuing to train the initial model by using the training set until the recognition accuracy of the initial model reaches the accuracy threshold, and determining the initial model as a preset recognition model.
The application provides a defrosting method of a refrigerator, comprising the following steps: detecting a storage state of a containing compartment of the refrigerator, wherein the refrigerator comprises a plurality of containing compartments which are mutually independent, and a heater is arranged in each containing compartment to acquire first frosting data of the containing compartment under the condition that the storage state is detected to be converted from a placing state to an empty state; generating a defrosting strategy corresponding to the first frosting data; the heater is controlled in accordance with a defrost strategy to defrost the receiving compartment.
