Present refrigeration compartment is generally through cold-stored sensor come the indoor temperature of control room, under this condition, when very high food of temperature is placed near temperature sensor, can lead to near temperature sensor local temperature higher, the refrigerator walk-in can request refrigeration always this moment, thereby lead to other regional temperature of walk-in low excessively, cause food to freeze, the scheduling problem freezes, influence the fresh-keeping effect of food, on the other hand, cold storage plant is in order to the quick cooling with article, need increase compressor load, lead to the refrigeration effect decline of refrigeration sources such as compressor, cause cold storage plant's energy consumption to rise, can shorten the working life of refrigeration source under the serious condition, power consumption increases simultaneously, can't satisfy energy-concerving and environment-protective requirement.
According to the refrigeration compartment temperature control method provided by the invention, when a temperature sensor detects that high-temperature food is put into the refrigeration compartment, the refrigeration compartment enters a high-temperature mode, and when the refrigeration compartment enters the high-temperature mode, the refrigeration of the compartment is controlled through the acquired starting time and the stopping time of the refrigeration cycle in the normal mode, so that the temperature in the compartment is regulated, the temperature control of the refrigeration compartment is not carried out according to the temperature measured by the sensor, the situation that the measured high-temperature is reduced to the stopping temperature by the continuous refrigeration of a refrigeration source, the food is frozen due to the fact that the temperature of other areas is too low, the food preservation effect of the food is further influenced is prevented, the food stored in the refrigeration compartment is prevented from being damaged due to the fact that the temperature is too low, the quality of the food stored in the refrigeration compartment is improved, the refrigeration reliability of the refrigeration compartment is improved, meanwhile, unnecessary energy consumption.
Referring to fig. 1, fig. 1 is a flowchart of a method for controlling a temperature of a refrigerating compartment according to an embodiment of the present invention, including the following steps:
step 1, obtaining the starting-up refrigeration time and the shutdown waiting time of the refrigeration cycle in the normal mode of the refrigeration chamber.
Specifically, the starting-up refrigeration time of the refrigeration chamber is the starting-up time of the refrigeration source, the shutdown waiting time of the refrigeration chamber is the shutdown time of the refrigeration source, the refrigeration control in the normal mode is temperature control, the starting-up temperature is the starting temperature at which the refrigeration source starts to work, and the shutdown temperature is the temperature at which the refrigeration source stops working, that is, the starting-up temperature and the shutdown temperature are respectively the starting point and the ending point of the operation of the refrigeration source. When the temperature sensor in the compartment detects that the temperature in the compartment is greater than or equal to the preset starting temperature of the refrigeration source, the refrigeration source starts to work to refrigerate the compartment, so that the temperature in the compartment is reduced; and when the temperature of the compartment measured by the temperature sensor is less than or equal to the preset shutdown temperature of the refrigeration source, the refrigeration source stops working. For example, the preservation temperature of the refrigeration chamber is 3-7 ℃, the refrigeration source is a compressor, after food is put in, when the temperature sensor detects that the temperature of the chamber is 12 ℃, the temperature of the chamber is reduced to 3 ℃ after the compressor works for 10 minutes, at the moment, the compressor stops working, after the compressor stops working for 60 minutes, the temperature is increased to more than 7 ℃ again, the compressor starts refrigeration again to carry out circulation, and the main control board obtains the starting time and the stopping time of the refrigeration cycle in the normal mode.
And 2, when the refrigerating chamber is detected to be in the door opening state, acquiring a first temperature value T1 acquired by a temperature sensor arranged in the refrigerating chamber.
Specifically, be provided with the door lamp switch in the refrigeration room, when opening the door, the lamp can be lighted, can detect out that refrigeration room is in the state of opening the door, utilizes the door lamp switch to gather the signal of opening the door. In this step, the first temperature value is a compartment temperature measured by the temperature sensor when the door opening operation is detected.
And 3, when the refrigerating chamber is detected to be in a door closing state, acquiring a second temperature value T2 sensed by a temperature sensor in the refrigerating chamber after the refrigerating chamber enters the door closing state for a first preset time.
The door closing state is a state that the refrigerating chamber enters through a door closing action after being in a door opening state.
The first preset time is 2-5 minutes, the specific time is determined according to the ambient temperature, for example, the ambient temperature is 14 ℃, the preservation temperature of the refrigeration chamber is 3-7 ℃, the temperature of the sensor rises due to fluctuation of the temperature in the refrigeration chamber after the door is opened, in one case, the temperature rises due to the fact that outdoor hot air enters the chamber after the door is opened and closed, the temperature sensor detects the temperature rise, the refrigeration source works after the door is closed, and the temperature detected by the sensor is reduced to the preservation temperature for at most 2 minutes; and the other condition is caused by placing hot food in the chamber, if the food is placed in the chamber, the temperature measured by the sensor is still higher than the preservation temperature after 2 minutes of refrigeration, so that the leading factor of the temperature rise of the sensor is determined through time delay detection, the second temperature value is obtained, and the accuracy of the detection result is ensured.
Step 4, if the temperature difference between the second temperature value T2 and the first temperature value T1 is greater than or equal to a first preset temperature, the refrigeration compartment enters a high-temperature mode, and the refrigeration frequency of the refrigeration compartment is the starting refrigeration duration and the stopping waiting duration of one refrigeration cycle in the normal mode;
preferably, the first preset temperature is 5-10 ℃, for example, the preservation temperature is 3-7 ℃, the first temperature value is 6 ℃, and the first preset temperature is 5 ℃, when the temperature difference is greater than or equal to 5 ℃, that is, the second temperature value is greater than or equal to 11 ℃, assuming that the working time of the refrigeration source for reducing the temperature from 11 ℃ to 3 ℃ is half an hour, if the normal mode is adopted for refrigeration, the refrigeration source will be stopped for half an hour to cause freezing damage of food in other areas of the compartment, therefore, when the temperature difference is greater than or equal to 5 ℃, it is considered that high-temperature food is placed in the compartment, so that the compartment enters the high-temperature mode, the refrigeration time of the refrigeration source is controlled by the time length of the refrigeration cycle before opening the door and the stop time length, the temperature in the compartment is adjusted (for example, the start time length of the refrigeration cycle before opening the door is 10 minutes, the stop time length is 60 minutes, and then the compartment enters the high-temperature mode, the starting time and the stopping time of the refrigeration cycle are 10 minutes and 60 minutes), and the working time of the refrigeration source is shortened through a high-temperature mode, so that the temperature of the refrigeration room is not too low, food is not frozen, the refrigeration effect can be ensured, and the satisfaction degree of users is improved.
In order to ensure the cooling efficiency, in one embodiment, the cooling compartment temperature control method further includes:
and 5, after the high-temperature mode is operated for a second preset time, acquiring a third temperature value T3 sensed by a temperature sensor in the compartment, judging whether the temperature difference between the third temperature value T3 and the first temperature value T1 is greater than or equal to a second preset temperature, if so, continuing to maintain the high-temperature mode, and if not, entering a normal mode.
Specifically, the second preset time is 2-4 hours, the second preset temperature is 4-6 ℃, for example, after the high-temperature mode operates for 3 hours, the temperature sensor detects and acquires a third temperature value in the current compartment, when the temperature difference between the third temperature value and the first temperature value is greater than or equal to 5 ℃, the temperature of the placed food is still considered to affect normal refrigeration, so that the high-temperature mode is continuously maintained until the temperature difference is reduced to be lower than 5 ℃, the high-temperature mode exits, the normal mode is entered, and the normal refrigeration efficiency is maintained, and the refrigeration effect and the refrigeration quality in the compartment are ensured by switching between the normal mode and the high-temperature mode.
It should be noted that the preset time and the preset temperature may be set by receiving a control instruction from a user, or may be factory settings.
