The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art. In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1, the refrigerator of the present embodiment includes a refrigerator body 1, a refrigerating compartment is formed in the refrigerator body 1, the refrigerating compartment of the present embodiment includes a refrigerating chamber 21 and a freezing chamber (not marked in the figure), and a door body (not shown in the door body of the refrigerating chamber 21) for closing the refrigerating compartment is provided on the refrigerator body 1, and the refrigerating compartment is used for storing articles.
In the present embodiment, a refrigeration compartment is taken as an example of the refrigerating compartment 21, and as shown in fig. 1 and 2, the refrigerator of the present embodiment includes:
a first temperature sensor 4, a second temperature sensor 5, and a third temperature sensor (not shown) are located in the refrigerating compartment 21 for detecting the temperature in the refrigerating compartment 21.
The first temperature sensor 4 and the second temperature sensor 5 are close to the mouth of the container to detect the temperature at the mouth of the container, so as to ensure that the first temperature sensor 4 and the second temperature sensor 5 can timely detect the temperature change when food is put into the refrigerating chamber 21. When the temperature detected by the first temperature sensor 4 or the second temperature sensor 5 rises to set a threshold value, the refrigerating chamber 21 is controlled to start refrigerating so as to ensure the timeliness of refrigerating the refrigerating chamber 21 and solve the problem of hysteresis of the position detection temperature of the temperature sensor in the prior art.
A third sensor is located inside the refrigeration compartment 21 (which may be located on a side wall or rear wall of the refrigeration compartment), detecting the internal temperature of the refrigeration compartment 21.
Further, the first temperature sensor 4 and the second temperature sensor 5 are arranged at a certain distance, so that a certain distance difference exists between the newly-placed food and the first temperature sensor 4 and the second temperature sensor 5, a certain temperature difference exists between the first temperature sensor 4 and the second temperature sensor 5, the quantity of the placed food is judged according to the relation of the temperature difference, the refrigerating state of the refrigerator is controlled according to the quantity of the food, and the refrigerating requirement of the food is fully met.
The refrigerating compartment 21 includes a partition for partitioning the refrigerating compartment 21 into at least two subspaces including a first subspace 211 and a second subspace 212, the first temperature sensor 4 being located in the first subspace 211, and the second temperature sensor 5 being located in the second subspace 212.
In the present embodiment, the partition is a partition 3 for partitioning the refrigerating compartment 21 into at least two subspaces arranged in the up-down direction, and the first subspace 211 is located above the second subspace 212. Since the first temperature sensor 4 is located in the first subspace 211 and the second temperature sensor 5 is located in the second subspace 212, the first temperature sensor 4 is located above the second temperature sensor 5.
The arrangement mode of the temperature sensor of the refrigerating chamber can improve the accuracy of detecting the quantity of food put into a user. When the user puts food into the first subspace 211, the temperature change sensed by the first temperature sensor 4 is stronger than that sensed by the second temperature sensor 5, when the food is put into the second subspace 212, the temperature change sensed by the second temperature sensor 5 is stronger than that sensed by the first temperature sensor 4, and the temperature difference change between the first temperature sensor 4 and the second temperature sensor 5 can accurately reflect the food put into the user.
The control module is used for acquiring the temperatures of the first temperature sensor 4 and the second temperature sensor 5 when the compressor is stopped and calculating the temperature difference X.
The control module is used for controlling the refrigerating chamber to start refrigerating when the temperature detected by the first temperature sensor 4 or the second temperature sensor 5 rises to set a threshold value after the compressor is stopped. The threshold value is set to any value of 3 to 7 ℃.
The control module is used for indicating that when the third temperature sensor does not reach the shutdown temperature after the set time, a user opens the door and puts food, and the food causes the temperature of the refrigerating chamber to rise, so that the third temperature sensor does not reach the shutdown temperature. The control module controls the refrigerating chamber to be in a refrigerating strengthening state so as to quickly cool the refrigerating chamber and offset the influence of newly-placed food on the temperature of the refrigerating chamber. The setting time is any value within 10-17 min.
Furthermore, the control module controls the refrigerating chamber to be in the enhanced refrigerating state and comprises a first enhanced refrigerating state and a second enhanced refrigerating state, and the refrigerating effect of the first enhanced refrigerating state is greater than that of the second enhanced refrigerating state.
In the embodiment, the amount of food put into the refrigerator by the user is judged according to the relationship between the increase of the temperature difference between the first temperature sensor 4 and the second temperature sensor 4 and the amplitude of the X and the set increase, and the refrigeration effect of the refrigerator is controlled according to the amount of food put into the refrigerator by the user, so that the refrigeration requirement of the product is further ensured.
Specifically, when the increase of the temperature difference between the first temperature sensor 4 and the second temperature sensor 5 and the increase of the X is larger than the set increase, the control module indicates that more food is put into the refrigeration compartment, and controls the refrigeration compartment to be in the first enhanced refrigeration state, otherwise, indicates that less food is put into the refrigeration compartment, and controls the refrigeration compartment to be in the second enhanced refrigeration state. For example, the amplification is set to 2 ℃.
For the direct cooling refrigerator, the first strengthening refrigeration state is that the compressor runs at high speed for the first set time; the second enhanced cooling state is that the compressor runs at high speed for a second set time.
For the air-cooled refrigerator, the first enhanced refrigeration state is that a fan corresponding to a compressor and a refrigeration chamber runs at a high speed for a first set time; the second enhanced refrigeration state is that the fan corresponding to the compressor and the refrigeration compartment runs at a high speed for a second set time.
The first set time is greater than the second set time.
The control module is used for controlling the refrigerating chamber to exit from the enhanced refrigerating state when the third temperature sensor reaches the shutdown temperature.
Because the refrigerator leads to the frosting amount of evaporimeter or the hidden danger of frosting increases after strengthening the refrigeration state, therefore, in order to guarantee the refrigeration effect of refrigerator, control module is used for controlling the first end temperature of defrosting process after first strengthening the refrigeration state and second strengthening the refrigeration state all to be higher than the end temperature of normal defrosting process, and further, the end temperature of first defrosting process after first strengthening the refrigeration state is higher than the end temperature of first defrosting process after the second strengthening the refrigeration state, guarantees that the defrosting state adjusts according to the regulation of refrigeration state, and is high at refrigeration intensity, when frosting is many, the time of defrosting is long, and is low at refrigeration intensity, when frosting is few, and the time of defrosting is few, guarantees the defrosting effect.
For example, the end temperature of the first defrosting process after the first enhanced cooling state is 3 ℃ higher than the end temperature of the normal defrosting process, and the end temperature of the first defrosting process after the second enhanced cooling state is 2 ℃ higher than the end temperature of the normal defrosting process

when the third temperature sensor does not reach the shutdown temperature after the set time, judging whether the amplification of the temperature difference between the first temperature sensor and the second temperature sensor and the temperature difference X is greater than the set amplification, if so, controlling the refrigeration chamber to be in a first enhanced refrigeration state, otherwise, controlling the refrigeration chamber to be in a second enhanced refrigeration state;
and controlling the refrigerating chamber to exit from the enhanced refrigerating state when the third temperature sensor does not reach the shutdown temperature.
The first enhanced refrigeration state is that the compressor runs at a high speed for a first set time or the compressor and a fan corresponding to the refrigeration chamber run at a high speed for a first set time; the second enhanced refrigeration state is that the compressor runs at a high speed for a second set time or the fan corresponding to the compressor and the refrigeration chamber runs at a high speed for a second set time, wherein the first set time is longer than the second set time.
And controlling the ending temperature of the first defrosting process after the first enhanced refrigerating state and the second enhanced refrigerating state to be higher than the ending temperature of the normal defrosting process.
And controlling the ending temperature of the first defrosting process after the first enhanced cooling state to be higher than the ending temperature of the first defrosting process after the second enhanced cooling state.
Specifically, as shown in fig. 3, the control flow of the air-cooled refrigerator of the present embodiment is as follows:
and S1, normally operating the refrigerator. The control module controls components such as a compressor, a fan, an air door and the like according to the actual temperature of the refrigerating chamber and the refrigerating requirement temperature, so that the refrigerating chamber meets the refrigerating requirement temperature.
And S2, acquiring the temperatures of the first temperature sensor and the second temperature sensor when the compressor is stopped and calculating the temperature difference X.
And S3, controlling the cooling chamber to start cooling when the temperature rise detected by the first temperature sensor or the second temperature sensor sets a threshold value. Specifically, the compressor is controlled to start and the fan is controlled to operate.
And S4, after the set time, judging whether the third temperature sensor reaches the shutdown temperature, if so, indicating that the user only opens the door and does not put food, and entering the step S1, otherwise, entering the step S5.
S5, judging whether the increase of the temperature difference between the first temperature sensor and the second temperature sensor and the temperature difference X is larger than the set increase, if so, indicating that the user puts more food, entering a step S6, controlling the refrigerating chamber to be in a first enhanced refrigerating state, otherwise, indicating that the user puts less food, entering a step S9, and controlling the refrigerating chamber to be in a second enhanced refrigerating state.
And S6, enabling the fans corresponding to the compressor and the refrigerating chamber to run at high speed for a first set time. Since the refrigerating intensity is increased and the frosting amount of the evaporator is increased, the first defrosting end temperature after the first intensive refrigerating state is higher than the end temperature of the normal defrosting process in the present embodiment.
And S7, judging whether the third temperature sensor reaches the shutdown temperature, if so, entering the step S8, otherwise, entering the step S6.
S8, since the refrigerating intensity is increased and the frost formation amount of the evaporator is increased, the first defrosting end temperature after the first intensive refrigerating state is higher than the end temperature of the normal defrosting process by 3 ℃. The process advances to step S1.
And S9, the fans corresponding to the compressor and the refrigerating chamber run at high speed for a second set time. Since the refrigerating intensity is increased and the frosting amount of the evaporator is increased, the first defrosting end temperature after the second intensive refrigerating state is higher than the end temperature of the normal defrosting process in the present embodiment.
And S10, judging whether the third temperature sensor reaches the shutdown temperature, if so, entering the step S11, otherwise, entering the step S9.
