Detailed Description
The embodiment firstly provides a refrigeration control method for a refrigerator, which can simplify a control flow, effectively prolong the working time of a refrigeration system, improve the refrigeration capacity after a new article is put in, and quickly reduce the temperature of the new article. Fig. 1 is a schematic view of a cooling control method of a refrigerator according to an embodiment of the present invention. As shown in fig. 1, the refrigeration control method of the refrigerator may perform the following steps:
step S102, a door closing signal of the refrigerator is obtained;
step S104, judging whether a new article is put into the storage chamber of the refrigerator, if so, executing step S106;
and step S106, adjusting both the starting temperature and the shutdown temperature of the storage chamber to a preset temperature and continuing for a preset time.
It should be noted that, the refrigerator to which the refrigeration control method of the refrigerator of the present embodiment is applied may generally include: a box body and a door body. The refrigerator body is internally limited with storage compartments, the number and the structure of the storage compartments can be configured according to requirements, and the storage compartments are configured into a cold storage compartment, a freezing compartment, a temperature changing compartment or a fresh-keeping compartment according to different purposes. Each storage compartment can be divided into a plurality of storage areas by a partition plate, and the articles are stored by racks or drawers. The door body is pivotally connected to the front side of the box body so that a user can open and close the storage compartment; the door bodies can be arranged corresponding to the storage chambers, namely, each storage chamber is provided with one or more door bodies correspondingly.
The refrigerator further includes: and the refrigerating system is configured to provide cold energy to the storage compartment. The refrigeration system may be a refrigeration cycle system including a compressor, a condenser, a throttle device, an evaporator, and the like. In some embodiments, the storage compartment may include a refrigeration compartment or a freezing compartment, and the refrigeration system provides different amounts of refrigeration to the refrigeration compartment and the freezing compartment such that the temperatures within the refrigeration compartment and the freezing compartment are also different. Wherein the temperature in the refrigerated compartment is generally between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. The temperature in the freezer compartment is typically in the range of-22 deg.C to-14 deg.C. In the prior art, a refrigeration system starts to work when the temperature in a storage room reaches a starting temperature, and stops working when the temperature in the storage room reaches a shutdown temperature. For example, if the startup temperature of the refrigerating chamber is 8 ℃ and the shutdown temperature is 3 ℃, the refrigerating system starts to work when the temperature of the refrigerating chamber reaches 8 ℃, the refrigerating system supplies cold energy to the refrigerating chamber, the temperature of the refrigerating chamber is reduced, and the refrigerating system stops working until the temperature of the refrigerating chamber reaches 3 ℃.
In the above steps, the door closing signal of the refrigerator obtained in step S102 may pass through a door detector, and the door detector may be a magnetic sensitive switch matched with the door and configured to change its switching signal according to the switching state of the door. The magnetic sensitive switch can also be replaced by a contact switch such as a sector switch. The door body detector can sense the opening and closing of the corresponding refrigerator door body, and only the corresponding storage chamber opened by the refrigerator door body judges whether a new article is put into the storage chamber, and if the door body is not opened, the new article cannot be put into the storage chamber.
In step S104, it is determined whether a new article is placed in the storage compartment of the refrigerator, and specifically, a weight measurement value of a weight sensor disposed at each storage area supporting portion in the storage compartment may be obtained, and it is determined whether a new article is placed according to a change in the weight measurement value. The weight-sensitive sensors are respectively arranged at the supporting parts of the storage areas, such as the supporting frames arranged at both sides of the refrigeration rack and the supporting frame of the freezing drawer. The weight-sensitive sensors measure the weight of the storage areas to determine the storage areas from the weight variations of each storage area. The weight change of each storage area has a preset value, and when the weight change value measured by the weight induction sensor is greater than or equal to the preset value, the occurrence of the operation of taking and placing the articles can be judged; and if the weight change value measured by the weight induction sensor is smaller than the preset value, the operation of taking and placing the articles is not considered to be generated. Specifically, the weight measured by the weight sensing sensor increases, and it is determined that an article is put into the refrigerator; the weight measured by the weight sensing sensor is decreased, and it is judged that the article is taken out of the refrigerator. The preset value can be configured according to the measurement error of the weight sensing sensor, so that misjudgment caused by the measurement error is prevented.
And S106, under the condition that the new articles are placed, the starting temperature and the shutdown temperature of the storage chamber are both reduced to preset temperatures and are continued for a preset time. In a specific embodiment, the preset temperature may be 2 ℃, that is, in the case where it is determined that a new article is put in, both the start-up temperature and the shut-down temperature of the storage compartment may be reduced by 2 ℃ for a preset time period. It should be noted that the specific values of the preset temperature are only examples, and are not limiting to the present invention, and in some other embodiments, the preset temperature may be set to other values.
According to the refrigeration control method of the refrigerator, the starting temperature and the shutdown temperature of the storage chamber are both reduced by the preset temperature under the condition that the new articles are determined to be put in, so that the refrigeration system can be started earlier and shut down later than the original switch and temperature, the control flow is simplified, the working time of the refrigeration system is effectively prolonged, the refrigerating capacity is increased after the new articles are put in, and the temperature of the new articles can be rapidly reduced. The startup and shutdown temperature is adjusted downwards and lasts for a preset time, and the startup and shutdown temperature is actually kept in a state after being adjusted downwards within the preset time, so that the reliability of prolonging the working time of the refrigeration system is ensured.
In some optional embodiments, the refrigerator may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the refrigeration control method of the refrigerator according to this embodiment in conjunction with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of a part of steps may be modified according to specific implementation requirements. Fig. 2 is a detailed flowchart of a cooling control method of a refrigerator according to an embodiment of the present invention, the cooling control method of the refrigerator including the steps of:
step S202, a door closing signal of the refrigerator is obtained;
step S204, acquiring weight measurement values of weight induction sensors arranged at supporting parts of all storage areas in the storage room;
step S206, judging whether a new article is put in according to the change of the weight measurement value, if so, executing step S208, and if not, executing step S216;
step S208, determining the weight of the new article according to the change of the weight measurement value;
step S210, acquiring a first temperature in the storage room and a second temperature outside the refrigerator;
step S212, calculating the product of the difference value of the second temperature and the first temperature, the weight of the new article and a preset adjusting coefficient as a preset duration;
step S214, the starting temperature and the shutdown temperature of the storage chamber are both reduced to preset temperatures and are continued for preset duration;
and step S216, keeping the starting temperature and the shutdown temperature of the storage compartment unchanged.
In the above steps, the preset adjustment coefficient in step S212 is inversely proportional to the cooling capacity of the refrigerator. That is, the stronger the refrigerating capacity of the refrigerator is, the smaller the preset adjustment coefficient is; the weaker the refrigerating capacity of the refrigerator is, the larger the preset adjustment coefficient is. Since the preset time length is the product of the difference between the second temperature and the first temperature, the weight of the new article and the preset adjustment coefficient, under the precondition that the difference between the second temperature and the first temperature and the weight of the new article are the same, if the refrigerating capacity of the refrigerator is weaker, the preset time length which lasts after the startup temperature and the shutdown temperature are adjusted down in step S214 needs to be longer, and therefore the preset adjustment coefficient can be set to be larger; if the refrigerating capacity of the refrigerator is stronger, the preset duration after the start-up temperature and the shutdown temperature are adjusted downward in step S214 needs to be shorter, so the preset adjustment coefficient can be set to be smaller.
It should be noted that, on the premise that the difference between the second temperature and the first temperature and the weight of the new article are positive numbers, the product of the difference between the second temperature and the first temperature, the weight of the new article and the preset adjustment coefficient is calculated as the preset duration. If the difference between the second temperature and the first temperature is less than 0, the second temperature outside the refrigerator is lower than the first temperature in the storage compartment, and the starting temperature and the shutdown temperature do not need to be adjusted downwards, so that the difference can be calculated according to 0. Similarly, if the weight of the new article is less than 0, it indicates that the weight measured by the weight sensing sensor is reduced, and the new article is not put into the refrigerator but taken out of the refrigerator, and at this time, the turn-on temperature and the turn-off temperature do not need to be adjusted downward, so the weight of the new article can be calculated as 0.
The refrigeration control method of the refrigerator of the embodiment determines the preset duration of the down-regulation startup and shutdown temperature according to the weight of a new article to be put in, the indoor and outdoor temperature difference of the storage room and the preset adjustment coefficient, so that the preset duration is matched with the weight of the new article to be put in, the indoor and outdoor temperature difference of the storage room and the refrigeration capacity of the refrigerator, the improvement of the whole refrigerating capacity of the storage room is ensured, the temperature of the new article is effectively reduced, the storage requirements of all the articles in the storage room can be met, the storage effect is improved, and the use experience of a user is improved.

Among the above modules, the signal acquiring module 310 may be configured to acquire a door closing signal of the refrigerator. Specifically, a door closing signal of the refrigerator can be obtained through a door detector, and the door detector can be a magnetic sensitive switch matched with a door and configured to change a switch signal of the door according to a switch state of the door. The magnetic sensitive switch can also be replaced by a contact switch such as a sector switch. The door body detector can sense the opening and closing of the corresponding refrigerator door body, and only the corresponding storage chamber opened by the refrigerator door body judges whether a new article is put into the storage chamber, and if the door body is not opened, the new article cannot be put into the storage chamber.
The article determination module 320 may be configured to determine whether a new article is placed in the storage compartment of the refrigerator. Specifically, the weight measurement value of the weight induction sensor arranged at each storage area supporting part in the storage compartment can be obtained, and whether a new article is put in or not is judged according to the change of the weight measurement value. The weight-sensitive sensors are respectively arranged at the supporting parts of the storage areas, such as the supporting frames arranged at both sides of the refrigeration rack and the supporting frame of the freezing drawer. The weight-sensitive sensors measure the weight of the storage areas to determine the storage areas from the weight variations of each storage area. The weight change of each storage area has a preset value, and when the weight change value measured by the weight induction sensor is greater than or equal to the preset value, the occurrence of the operation of taking and placing the articles can be judged; and if the weight change value measured by the weight induction sensor is smaller than the preset value, the operation of taking and placing the articles is not considered to be generated. Specifically, the weight measured by the weight sensing sensor increases, and it is determined that an article is put into the refrigerator; the weight measured by the weight sensing sensor is decreased, and it is judged that the article is taken out of the refrigerator. The preset value can be configured according to the measurement error of the weight sensing sensor, so that misjudgment caused by the measurement error is prevented.
The temperature adjustment module 330 may be configured to adjust both the start-up temperature and the shut-down temperature of the storage compartment down by a preset temperature for a preset duration when a new item is placed in the storage compartment. The refrigerating system is started earlier and shut down later than the original switch and temperature, the control flow is simplified, the working time of the refrigerating system is effectively prolonged, the refrigerating capacity is increased after new articles are put in, and the temperature of the new articles can be rapidly reduced. The startup and shutdown temperature is adjusted downwards and lasts for a preset time, and the startup and shutdown temperature is actually kept in a state after being adjusted downwards within the preset time, so that the reliability of prolonging the working time of the refrigeration system is ensured.
Fig. 4 is a block diagram illustrating a refrigeration control apparatus 300 of a refrigerator according to another embodiment of the present invention, in which a set weight determining module 340, a temperature acquiring module 350, and a time period calculating module 360 may be flexibly added on the basis of the above embodiment.
The article determining module 320 in this embodiment may be further configured to: the weight measurement value of the weight induction sensor arranged at the supporting part of each storage area in the storage room is obtained, and whether a new article is put into the storage room is judged according to the change of the weight measurement value. The weight determination module 340 may be configured to determine the weight of the new item based on a change in the weight measurement. The temperature acquisition module 350 may be configured to acquire a first temperature inside the storage compartment and a second temperature outside the refrigerator.
The time period calculation module 360 may be configured to calculate a product of a difference between the second temperature and the first temperature, a weight of the new item, and a preset adjustment coefficient as the preset time period, wherein the preset adjustment coefficient is inversely proportional to a refrigerating capacity of the refrigerator. That is, the stronger the refrigerating capacity of the refrigerator is, the smaller the preset adjustment coefficient is; the weaker the refrigerating capacity of the refrigerator is, the larger the preset adjustment coefficient is. Because the preset time length is the product of the difference between the second temperature and the first temperature, the weight of the new article and the preset adjustment coefficient, under the precondition that the difference between the second temperature and the first temperature and the weight of the new article are the same, if the refrigerating capacity of the refrigerator is weaker, the continuous preset time length after the startup temperature and the shutdown temperature are adjusted downwards needs to be longer, and therefore the preset adjustment coefficient can be set to be larger; if the refrigerating capacity of the refrigerator is stronger, the preset duration after the startup temperature and the shutdown temperature are adjusted downwards needs to be shorter, so that the preset adjustment coefficient can be set to be smaller.
The refrigeration control device 300 of the refrigerator of the embodiment reduces the starting temperature and the shutdown temperature of the storage compartment to preset temperatures, so that the refrigeration system can be started earlier and shut down later than the original switch and temperature, the control flow is simplified, the working time of the refrigeration system is effectively prolonged, the refrigerating capacity is increased after new articles are put in, and the temperature of the new articles can be rapidly reduced. The startup and shutdown temperature is adjusted downwards and lasts for a preset time, and the startup and shutdown temperature is actually kept in a state after being adjusted downwards within the preset time, so that the reliability of prolonging the working time of the refrigeration system is ensured.
