Background
With the continuous change of the requirements of the refrigerator users, the functions of the refrigerator are also more and more abundant. In order to satisfy different storage purposes of users, the existing refrigerator is provided with a plurality of compartments, and the temperatures of the compartments are different. Each compartment is determined to be refrigerated or not according to the requirements of users. When the temperature requirements of the compartments are different, the temperature of each compartment is controlled through a refrigerator air door. The temperature control of the refrigerator air door is mainly realized through an air door motor, the cold air flow can be adjusted by the work of the air door motor, and further the control of the compartment temperature is realized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.
In order to avoid the situation that the refrigerator air door is frozen due to the fact that the humidity of accessories of the refrigerator is too high and the condensation problem occurs, the method for controlling the freezing prevention is provided.
Fig. 1 is a flowchart of a method for controlling anti-freezing of a damper of a refrigerator according to an embodiment of the present invention. Referring to fig. 1, a method for controlling anti-freezing of a damper of a refrigerator includes:
step 101: and acquiring the target refrigerating temperature of the refrigerator compartment set by a user. When a user needs to change the temperature of a certain compartment in the refrigerator, the compartment refrigerating temperature required by the user is input through a temperature adjusting button on the refrigerator, and the input temperature information input by the user can be received by the refrigerator after the input, namely the target refrigerating temperature.
Step 102: and judging whether to execute a preset continuous heating mode according to the target refrigerating temperature. And judging whether the temperature is different from the last temperature input by the user or not according to the target refrigeration temperature, if so, indicating that the user demand is changed, and executing the continuous heating mode at the moment.
Step 103: and if the continuous heating mode is executed, controlling the heating part arranged on the refrigerator air door to continuously work for a set time, and heating the refrigerator air door. The heating component is installed on the air door component of the refrigerator air door, and when the continuous heating mode is judged to be needed, a control command is generated to the heating component, so that the heating component works continuously, namely, the heating is continued for a period of time. In this embodiment, the setting time is 15 min. The specific selection of the set time is not exclusive and can be determined according to parameters such as the model of the refrigerator.
Step 104: and if the continuous heating mode is not executed, determining the on-off rate of the heating component according to the acquired humidity of the position of the refrigerator air door so as to heat the refrigerator air door according to a preset intermittent heating mode. When the target refrigerating temperature is judged and the temperature requirement of a user is not changed, the heating part does not need to be heated continuously, the on-off rate of the heating part is determined according to the humidity near the refrigerator air door, and the heating part works according to the on-off rate. The on-off ratio refers to the relationship of the heating element being turned on and off. For example, the duty cycle of the heating element in this application is 10s, and the 30% on-off ratio refers to: on 3s, off 7 s.
According to the method, whether the user demand changes or not is judged according to the target refrigeration temperature set by the user, if yes, the heating component is controlled to continuously heat for a period of time, and if the user demand does not change, the on-off rate of the heating component is determined according to the humidity near the refrigerator air door, and heating is carried out according to the on-off rate. According to the method, the working mode of the heating part of the refrigerator air door is selected according to the temperature set by the user, and when the user demand changes, the heating part is heated for a period of time continuously, so that frost on the air door caused by the change of the temperature can be completely purified, and the freezing prevention efficiency of the refrigerator is improved. Simultaneously when user's demand does not change, utilize near humidity of refrigerator air door to decide heating element's on-off ratio to this guarantees that heating part can not work the heating always in refrigerator normal use, can heat according to the actual condition of frosting of refrigerator air door, with this work energy consumption that has greatly reduced the refrigerator, has improved user experience.
Meanwhile, in order to describe the anti-freezing control method in the above embodiment in more detail, the present application further provides another embodiment, which is as follows:
fig. 2 is a flowchart of a method for controlling anti-freezing of a damper of a refrigerator according to another embodiment of the present invention. Referring to fig. 2, a method for controlling anti-freezing of a damper of a refrigerator includes:
step 201: and acquiring and storing the target refrigerating temperature of the refrigerator compartment set by a user. When the user sets the temperature on the refrigerator, the set temperature of the user can be acquired in real time, and the temperature set by the user is stored.
Step 202: and determining the target refrigerating temperature set by the user last time as the original refrigerating temperature. After the user sets the temperature, the time that the user set the temperature can also be recorded when receiving the temperature that the user set up, and then can transfer the temperature of setting each time of user and the corresponding time of setting according to time information. When the user resets every time, the last setting time can be called up, and then the last set temperature, namely the last set target refrigeration temperature of the user can be called up according to the setting time.
Step 203: and judging whether the newly acquired target refrigeration temperature is consistent with the original refrigeration temperature. When the target refrigeration temperature set by the user latest is not consistent with the original refrigeration temperature, the change of the user requirement is indicated, and if the target refrigeration temperature and the original refrigeration temperature are consistent, the change of the user requirement is not indicated.
Step 204: and when the target refrigerating temperature is inconsistent with the original refrigerating temperature, executing the continuous heating mode, namely controlling a heating component arranged on the refrigerator air door to continuously work for a set time to heat the refrigerator air door. When the user's demand changes, the heating member needs to be operated for a certain period of time. Thereby avoiding the serious condensation problem caused by the temperature change. It should be noted that the default heating section enters the intermittent heating mode after the heating section continues to heat for a set time.
Step 205: and acquiring the humidity at the set position of the refrigerator air door. The refrigerator air door accessory is provided with a humidity sensor for detecting the humidity near the refrigerator air door.
Step 206: and determining the on-off rate of the heating component by combining a preset corresponding rule with the humidity. And determining the on-off rate of the heating component according to the humidity near the air door of the refrigerator and the preset corresponding relation of humidity and the on-off rate.
When a user sets a new temperature, an action instruction is sent to the refrigerator air door, after the refrigerator air door receives the action instruction, the heating component is started for 15min, and the refrigerator air door acts again, so that the problem that the instruction fails because the air door is frozen is solved. When the refrigeration requirement of any compartment is not changed, namely the air door does not need to act, the refrigerator air door works according to the corresponding relation of humidity and on-off rate near the heating part, and the condition that the refrigerator air door is frozen due to condensation caused by excessive humidity near the refrigerator air door is avoided. The on-off rate of the heating component is in direct proportion to the humidity near the refrigerator air door, and the higher the humidity is, the higher the on-off rate is.
Above-mentioned embodiment is after receiving the temperature that the user set up, transfer the last temperature that sets up of user, whether need continuously heat according to twice temperature setting decision heater block, if need, then the heater block continuously heats the settlement time, if need not, then acquire the humidity that near refrigerator air door humidity transducer detected, then decide heating element's on-off ratio according to this humidity, heating element works with this on-off ratio, thereby avoid the condition that the refrigerator air door takes place to freeze, avoid simultaneously because of the heating wire waste electric energy of long-time work when humidity is little, perhaps heat the work effect under the condition of high humidity and lead to near the condensation of air door, and then freeze the air door, make the air door unable action.
Still further, the method in the present application further comprises: receiving user operation information; and executing the continuous heating mode according to the user operation information. In the embodiment, the user can directly select to execute the continuous heating mode, for example, when the user feels that the refrigerator air door is likely to cause the refrigerating effect of the refrigerator to be less than ideal because of condensation, the user can autonomously select to make the heating component perform the continuous heating mode.
Meanwhile, in order to avoid stopping the continuous heating mode because the frost formation of the refrigerator air door is not completely purified, the present embodiment further includes: acquiring frost layer thickness information sent by preset air door frost layer detection equipment; and judging whether to stop the continuous heating mode according to the frost layer thickness information. A frost layer thickness detection component is arranged outside the refrigerator air door, and can detect the frost layer thickness on the refrigerator air door, so that the condensation and frost conditions of the refrigerator air door can be more clearly known, and whether the heating component executes the continuous heating mode or not is controlled according to the actual conditions.
According to the embodiment, the heating part continuous heating mode can be selected more autonomously according to the requirements of a user, the autonomous control of the user on the continuous heating of the heating part is realized, the frost layer thickness of the refrigerator air door can be detected, the heating mode of the heating part is controlled according to the actual condition of the thickness, and the practicability and the efficiency of freezing prevention of the refrigerator air door are greatly improved.
To describe the implementation process of the anti-freezing control method in the present application in more detail, the following description is given by way of example:
a user sets the temperature of one chamber in the refrigerating chamber to be 4 ℃ through a temperature adjusting button on a refrigerator door at 15:12 time division, and after the user sets the temperature, the refrigerator receives the temperature information set by the user, wherein the temperature information is 4 ℃ and the setting time is 15: 12. And then, calling the previously stored temperature set by the user, and traversing the stored historical data to obtain that the last time the temperature of the user is adjusted is 10:15 minutes, and the set temperature is 6 ℃. Since the user sets the temperature to 4 degrees this time and the temperature set for the last time is 6 degrees, the set temperatures of the two times are different and changed. At this time, the heating wire is controlled to work, and the heating is continued for 15 min. And after the heating is continuously carried out for 15min, the default heating wire enters an intermittent heating mode, the humidity sensor arranged at the refrigerator air door can detect the humidity near the refrigerator air door, the humidity near the refrigerator air door is 65% after detection, the on-off rate of the heating part is determined to be 30% according to the humidity-on-off rate contrast relation set when the refrigerator leaves a factory, the heating wire is controlled to work for 3s at the moment, and the heating wire is stopped for 7s, so that the refrigerator air door is ensured not to be frozen.
