The heat conducting plate 20 can be installed at any position in the refrigerator, and a first space and a second space having a temperature difference are formed at both sides of the heat conducting plate 20, so that condensation can be generated on the surface of the heat conducting plate 20. The type of the first space and the second space is not limited, for example, the first space may be an air-cooled space provided with an evaporator, and the second space may be a storage space for storing articles such as a refrigerating chamber, a freezing chamber, and a temperature-changing chamber.

In this embodiment, specifically, the refrigerator includes a container and a heat conducting plate 20 installed in the container, the heat conducting plate 20 divides the inner space of the container into an air-cooling space and a storage space for storing articles, and the heat conducting plate 20 is provided with an air guiding hole for penetrating the air-cooling space and the storage space; the heat transfer plate 20 is provided with an air guide unit 10 controlled by a controller 1001, the air guide unit 10 is movable to open, partially open, or close the air guide hole, and when the air guide hole is opened, air in the air-cooled space can flow to the storage space and blow to the heat transfer plate 20.

In the technical scheme provided by the invention, the heat conducting plate 20 divides the inner space of the refrigerator liner into an air cooling space and a storage space. The heat conducting plate 20 can be made of a metal plate with good heat conducting performance, and then low temperature generated by the air cooling space can be conducted to the storage space through the heat conducting plate 20, so that the storage space is cooled. It can be understood that, in the refrigeration process of the refrigerator, due to the temperature difference between the two sides of the heat conducting plate 20, condensation may be generated on the surface of the heat conducting plate 20 on the side opposite to the air cooling space, which further affects the humidity of the storage space and affects the preservation performance of the refrigerator.

In this embodiment, the heat conducting plate 20 is provided with air guiding holes, one side of the heat conducting plate 20 facing the storage space is provided with the air guiding assembly 10, and the air guiding assembly 10 can move to open or close the air guiding holes, so that when the air guiding holes are opened, the air in the air cooling space can circulate to the storage space and blow to the heat conducting plate 20; when the air guide hole is closed, the air in the air cooling space can not enter the storage space, so that the air cooling space and the storage space are two independent spaces. Therefore, by providing the air guide assembly 10, the air flow between the air-cooled space and the storage space can be controlled according to the cooling condition of the refrigerator. The fan is disposed in the air-cooling space to circulate air in the air-cooling space, and the air in the air-cooling space can be blown to the surface of the heat-conducting plate 20 through the air-guiding holes and the air-guiding assembly 10, so that condensation generated on the surface of the heat-conducting plate 20 can be effectively dried, and the humidity of the storage space can be ensured.

Referring to fig. 3, the air guide assembly 10 includes an air guide bar 11 and a movable member 12, the air guide bar 11 is disposed on one side of the heat conduction plate 20 facing the storage space, the movable member 12 is disposed on one side of the heat conduction plate 20 facing the air cooling space, and the movable member 12 can move along the surface of the heat conduction plate 20; the air guide bar 11 is provided with an air guide groove 113 penetrating the air guide hole so that the air passing through the air guide hole is blown to the heat guide plate 20. That is to say, the air guide strip 11 and the heat conducting plate 20 are fixedly connected, the air guide strip 11 cannot move, and the movable member 12 is located in the air cooling space and can move along the surface of the heat conducting plate 20, so as to achieve the purpose of opening or closing the air guide hole. It can be understood that the connection surface of the movable member 12 and the heat conductive plate 20 can be a horizontal surface, and the movable member 12 moves close to the surface of the heat conductive plate 20, so that when the movable member 12 moves to cover the air guiding hole, the purpose of closing the air guiding hole can be better achieved, and air in the air cooling space is prevented from entering the storage space. The air guide bar 11 is provided with an air guide groove 113 communicated with the air guide hole, when the moving part 12 moves far away from the air guide hole, air in the air cooling space enters the air guide groove 113 through the air guide hole under the action of the fan and is blown to the surface of the heat guide plate 20 through the air guide groove 113, so that condensation formed on the surface of the heat guide plate 20 is dried, the surface of the heat guide plate 20 is prevented from generating condensation, and the humidity of the storage space is ensured.

In an embodiment of the present invention, the air guiding strip 11 includes a first side 111, a second side 112 and a third side connected in sequence, the second side 112 is connected to the heat conducting plate 20; the air guiding groove 113 penetrates the first side surface 111, the second side surface 112 and the third side surface, and the flow direction of the air guiding groove 113 is perpendicular to the extending direction of the air guiding strip 11. In this embodiment, the air guide strip 11 is disposed horizontally, the air guide groove 113 is disposed opposite to the air guide hole, and the flow direction of the air guide groove 113 is vertical. That is, the air entering the air guide groove 113 from the air guide hole can be blown upward or downward by the fan, so that the air passing through the air guide strip 11 can cover the surface of the heat conducting plate 20 to a greater extent.

Referring to fig. 5, in another embodiment of the present invention, the air-guiding strip 11 includes a first side 111, a second side 112 and a third side connected in sequence, the second side 112 is connected to the heat-conducting plate 20, and the air-guiding groove 113 penetrates through the first side 111 and the second side 112; the number of the air guide assemblies 10 is at least one, one air guide assembly 10 is arranged at the edge of the heat conducting plate 20, and the notch of the air guide groove 113 on the air guide strip 11 faces the heat conducting plate 20. In this embodiment, the heat conducting plate 20 is square, the number of the air guiding assemblies 10 is four, and the four air guiding assemblies 10 are correspondingly disposed on four edges of the square heat conducting plate 20. That is, the heat conducting plate 20 is provided with four movable members 12 at one side facing the air cooling space, the heat conducting plate 20 is provided with four air guide strips 11 at one side facing the storage space, and the connecting lines of the four air guide strips 11 are square. The air guiding groove 113 penetrates through two adjacent side faces of the air guiding strip 11, and the air guiding groove 113 comprises a notch facing the air guiding hole and another notch for ventilation, that is, the air guiding strip 11 is ventilated on one side. The wind-guiding mouth on the wind-guiding strip 11 is towards the heat-conducting plate 20 middle part, also makes four wind-guiding strips 11 all blow towards the heat-conducting plate 20 middle part, and then can play the air-dry effect to the surface of heat-conducting plate 20 more intensively, prevents the production of condensation.

Further, the number of the air guiding holes and the number of the air guiding grooves 113 are both multiple, and the number of the air guiding grooves 113 is the same as the number of the air guiding holes. Specifically, one air guiding hole corresponds to one air guiding groove 113, and a plurality of air guiding holes are arranged in parallel on the heat conducting plate 20. For example, the plurality of air guiding holes arranged side by side are a set of air guiding holes, and the heat conducting plate 20 may include a plurality of sets of air guiding holes, so that the air in the air cooling space can enter the storage space more, and the air in the air cooling space can be blown to the surface of the heat conducting plate 20 more orderly, thereby better performing the functions of air drying and condensation prevention on the heat conducting plate 20.

Referring to fig. 4, a plurality of protrusions 121 are disposed on a side of the movable element 12 facing the heat conducting plate 20, the number of the protrusions 121 is equal to the number of the air guiding holes, and the protrusions 121 can be accommodated in the air guiding holes along with the movement of the movable element 12 to block the air guiding holes. Specifically, the size of the protrusion 121 on the movable member 12 is matched with the size of the air guide hole, so that when the protrusion 121 is accommodated in the air guide hole, the effect of closing the air guide hole can be achieved, and air in the air cooling space is prevented from entering the storage space through the air guide hole.

With reference to fig. 4, the air guiding assembly 10 further includes a driving device 13, and the driving device 13 is used for driving the movable element 12 to move along the surface of the heat conducting plate 20 in parallel. In this embodiment, the driving device 13 includes a motor and a gear, the gear is connected to the movable member 12, the motor is connected to a controller 1001 of the refrigerator, and the power on/off and the current direction of the motor are controlled by the controller 1001. It will be appreciated that the motor causes the direction of rotation of the gear to change by a change in the direction of the current. For example, a forward current causes the gear to rotate in a forward direction and a reverse current causes the gear to rotate in a reverse direction. The gear respectively drives the movable member 12 to move upwards or downwards through positive rotation and negative rotation, so that the movable member 12 can open or close the air guide hole. It can be understood that parameters such as the rotation period and the rotation rate of the motor can be set by the controller 1001 of the refrigerator, so that the movable member 12 realizes the periodic movement, and the intelligent control of the movable member 12 is realized.

Referring to fig. 2, a partition plate 21 is further disposed on one side of the heat conducting plate 20 facing the air cooling space, the air cooling space is divided into a main air duct and a return air duct by the partition plate 21, and a through hole is formed in the partition plate 21 so that air in the air cooling space circularly flows between the main air duct and the return air duct; the movable member 12 penetrates the through hole and is movable within the through hole.

In this embodiment, the partition 21 is vertically disposed, the moving member 12 is horizontally disposed, and the moving member 12 penetrates through the through hole and can move up and down in the through hole. That is, the size of the through hole is larger than that of the moving member 12, so that a gap is left after the moving member 12 is accommodated in the through hole, and air circulation between the main air duct and the return air duct is facilitated.

Preferably, the mobile element 12 is perpendicular to the partition 21. For example, when the partition 21 is disposed in the lateral direction, the movable member 12 is disposed in the vertical direction. It should be noted that the height of the movable member 12 is smaller than the height of the partition 21, that is, the end of the movable member 12 away from the heat conducting plate 20 does not abut against the tank, and the arrangement of the movable member 12 does not obstruct the circulation of air in the main air duct or the return air duct.

Furthermore, the extension length of the air guide strip 11 is less than or equal to the length of the edge of the heat conducting plate 20, and the extension length of the movable piece 12 is less than or equal to the length of the edge of the heat conducting plate 20. In this embodiment, the extension length of the air guide strip 11 is equal to the length of the edge of the heat conducting plate 20, and the extension length of the movable element 12 is equal to the length of the edge of the heat conducting plate 20. With such an arrangement, the air guide assembly 10 can guide the air in the air cooling space into the storage space over a larger area and blow the air onto the surface of the heat conduction plate 20, thereby ensuring that the surface of the heat conduction plate 20 can be covered with the air, and further ensuring the air drying effect of the air guide assembly 10 on the condensation generated on the surface of the heat conduction plate 20.

The movable part 12 and the air guide strip 11 can be plastic or metal parts, and the air guide strip 11 can be fixed with the heat conducting plate 20 by adopting a screw connection, bonding or clamping manner.

When the current humidity data is larger, the ventilation area of the air guide hole can be increased, so that the air quantity is conveyed faster, and a faster condensation air drying effect is achieved; on the contrary, when the current humidity data is smaller, the ventilation area of the air guide holes can be adjusted to be smaller, so that the air quantity is conveyed more slowly, the condensation air-drying effect can be achieved, and the humidity in the storage space can be prevented from falling below the lower limit value of the allowable humidity in a short time.

Further, in the present invention, the air guiding assembly 10 can move up and down to open or close the air guiding hole, when the air guiding opening is opened, the cold air in the air cooling space is blown to the storage space through the air guiding opening, and the air guiding assembly 10 is provided with the air guiding strip 11 to blow the air to the heat guiding plate 20. The condensation of the heat conducting plate 20 is prevented or the condensation is dried by forced convection of air. When the humidity conditions of the storage space are different, the upward movement distance of the air guide assembly 10 is different, and the opening size of the air guide opening is also different.

Referring to fig. 8, based on the first embodiment of the anti-condensation control method for the refrigerator of the present invention, in the second embodiment of the anti-condensation control method for the refrigerator of the present invention, the step S20 specifically includes:

step S21, acquiring a plurality of preset humidity level intervals;

step S22, comparing the current humidity data with the humidity level interval to determine the current humidity level interval corresponding to the current humidity data;

step S23, controlling the air guiding assembly to move on the air guiding hole according to the current humidity level interval, so as to correspondingly adjust the ventilation area of the air guiding hole, thereby adjusting the air exchange amount between the first space and the second space.

The number of humidity level sections may be set as needed, and in this embodiment, the number of humidity level sections is M. M is any positive integer. The upper limit value and the lower limit value of each humidity level interval can be set according to needs, and the difference between the upper limit value and the lower limit value of each humidity level interval can be equal or unequal. In this embodiment, the larger the current humidity data is, the higher the corresponding humidity level interval is, and meanwhile, the larger the ventilation area of the air guide hole can be; the smaller the current humidity data is, the lower the corresponding humidity level interval is, and meanwhile, the smaller the ventilation area of the air guide hole can be.

Further, the anti-condensation control method of the refrigerator may further include the steps of:

after the step S23, the method further includes:

The first mapping relation table stores a plurality of humidity level interval data and a plurality of ventilation time data, and each humidity level interval can correspond to a unique ventilation time in the first mapping relation table. The first mapping relation table is stored in the system so as to preset the ventilation time corresponding to each humidity level interval in the system, and the ventilation time can be set according to the needs of a user or is set in a default mode. The user may also adjust the respective ventilation times.

Referring to fig. 9, based on the second embodiment of the anti-condensation control method for the refrigerator according to the present invention, in the third embodiment of the anti-condensation control method for the refrigerator according to the present invention, the step S23 specifically includes:

step S23a, acquiring a second mapping relation table of humidity level intervals and ventilation gears, wherein the ventilation areas of the air guide holes corresponding to the ventilation gears are different;

step S23b, determining the current ventilation gear of the wind guide assembly to the wind guide hole according to the current humidity level interval and the second mapping relation table;

step S23c, according to the current ventilation gear, controlling the air guide assembly to move on the air guide hole, so that the ventilation area of the air guide hole is consistent with the ventilation area corresponding to the current ventilation gear.

The second mapping relation table stores a plurality of humidity level interval data and a plurality of ventilation gear data, and each humidity level interval can correspond to a unique ventilation gear in the second mapping relation table. The second mapping relation table is stored in the system. Wherein the plurality of humidity level section data in the second mapping table may be the same as the plurality of humidity level section data in the first mapping table. In this embodiment, the air guiding hole is completely closed, and the corresponding ventilation gear is the 0 gear. The air guiding assembly 10 can move from a state of completely closing the air guiding hole to a state of completely opening the air guiding hole. Specifically, the air guiding assembly 10 completely opens the air guiding hole when moving M steps in the set direction from the position where the air guiding hole is completely closed, and the corresponding ventilation gear is the M gear at this time. When the air guide assembly 10 runs in the set direction for X (X is more than 0 and less than M), the air guide opening is opened by X/M, and at the moment, the corresponding ventilation gear is an X gear. The ventilation areas of the air guide holes corresponding to the ventilation gears are different, so that the understanding is easy, in the embodiment, the larger the ventilation gear is, the larger the ventilation area is, and the faster the condensation drying speed is; conversely, the smaller the ventilation gear is, the smaller the ventilation area is, and the slower the condensation drying speed is.

The anti-condensation control method can be specifically carried out by referring to the following control modes:

the initial position of the air guiding assembly 10 is a position of completely closing the air guiding hole, that is, the air guiding hole is closed, and this position corresponds to the 0 th gear.

Detecting whether the current humidity data of the storage space is less than or equal to N1, when the humidity of the storage space is less than or equal to N1, the air guide assembly 10 moves to 1 gear, the size of an air guide opening is 1/M, and the opening time is T1.

When the current humidity data of the storage space is larger than N1, detecting whether the current humidity data of the storage space is smaller than or equal to N2, and when the current humidity data of the storage space is smaller than or equal to N2, the air guide assembly 10 moves to 2 grades, the size of an air guide opening is 2/M, and the opening time is T2.

……

When the current humidity data of the storage space is larger than N (M-2), whether the current humidity data of the storage space is smaller than or equal to N (M-1) is detected, and when the current humidity data of the storage space is smaller than or equal to N (M-1), the air guide assembly 10 moves to an opening position of an air guide opening of an M-1 gear, wherein the opening time is T (M-1)/M.

When the current humidity data of the storage space is larger than N (M-1), the air guide assembly 10 moves to an M gear, the air guide opening is completely opened, and the opening time is TM.

Wherein, the humidity data is N1 < N2 < N3 < … … < N (M-1) < NM; t1 and T2 … … TM can be set according to specific situations, and have no specific size relationship. In this embodiment, as the gear is higher, the ventilation area of the air guiding opening may be larger, and therefore, the opening time of the air guiding opening may be reduced step by step.

Referring to fig. 10, in a fourth embodiment of the anti-condensation control method for a refrigerator according to any one of the first to third embodiments of the anti-condensation control method for a refrigerator of the present invention, after step S20, the method further includes:

step S30, temperature data of the second space after the ventilation time of the air guide hole reaches a first set time is obtained;

step S40, comparing the temperature data with a set temperature of the second space to determine a difference between the temperature data and the set temperature;

and step S50, controlling the air guide assembly to close the air guide hole when the difference value is larger than or equal to a set value.

When the air guide hole is opened, the air in the first space enters the second space to reduce the temperature in the second space, and particularly, the cold air in the air cooling space enters the storage space to reduce the temperature in the storage space. In order to maintain the storage condition in the storage space, the temperature value in the storage space can only be allowed to decrease by a set value at a set temperature value. In order to prevent the temperature value in the storage space from exceeding the set range, the temperature data in the storage space may be acquired once every first set time, and when the difference between the temperature data in the storage space and the set temperature is greater than or equal to the set value, the air guide assembly 10 is controlled to reset to the 0-gear, that is, the air guide assembly 10 is controlled to close the air guide hole.

The set value can be set according to the requirement, and in this embodiment, the range of the set value can be 1 ℃ to 4 ℃, for example, the set value is 2 ℃. The set value can be set according to the specific conditions such as the climate type or the energy-saving mode. The value of the first set time T may be set as required, and in this embodiment, T may be T1-TM.

Referring to fig. 11, in a fifth embodiment of the anti-condensation control method for a refrigerator according to any one of the first to fourth embodiments of the anti-condensation control method for a refrigerator of the present invention, after step S20, the method further includes:

step S60, humidity data of the second space after the ventilation time of the air guide hole reaches a second set time is obtained;

and step S70, controlling the air guide assembly to close the air guide hole when the humidity data reaches the set humidity lower limit value of the second space.

The air in the first space entering the second space changes the humidity conditions in the second space. For example, the air in the air-cooled space is drier and less humid than the air in the storage space. Therefore, the air in the air-cooled space enters the storage space, and the humidity of the storage space is affected to some extent. In this embodiment, a lower limit humidity value may be set, and when it is detected that the humidity data in the storage space reaches the lower limit humidity value, the air guiding assembly 10 may be controlled to reset to 0 th position to close the air guiding hole.

Referring to fig. 12, in a sixth embodiment of the anti-condensation control method for the refrigerator, based on any one of the first to fifth embodiments of the anti-condensation control method for the refrigerator according to the present invention, the first space is an air-cooled space, and the second space is a storage space in the refrigerator; before the step S10, the method further includes:

step S80, detecting whether the door body of the second space is opened;

when the door body of the second space is closed, the step S10 is executed: and acquiring current humidity data in the second space.

In order to make the condensation prevention control more effective, the movement of the air guide assembly 10 may be controlled when a predetermined condition is satisfied. In the present embodiment, whether or not the door of the storage space is open is defined as a control condition for moving the air guide unit 10. When the storage space is a refrigerating chamber, the door body of the storage space is a refrigerating chamber door.

The storage space is in the open state when the door body is opened, and the open storage space is not beneficial to blow-dry condensation, so that when the door body is opened, the air guide assembly 10 can be kept in the state of closing the air guide hole, or the air guide assembly 10 can be reset to the state of closing the air guide hole from other positions. Specifically, the state of the door body of the storage space may be detected once every set time.

Referring to fig. 13, according to a sixth embodiment of the anti-condensation control method for the refrigerator of the present invention, in a seventh embodiment of the anti-condensation control method for the refrigerator, when the door of the storage space is closed, the anti-condensation control method for the refrigerator further performs the following steps:

step S90, detecting whether the evaporator in the first space is in a defrosting state;

when the evaporator is not in the defrosting state, the step S10 is executed: and acquiring current humidity data in the second space.

When the evaporator of the air-cooled space is in a defrosting state, the temperature in the air-cooled space is high, and at this time, if the air in the air-cooled space is introduced into the storage space, the temperature in the storage space will be increased, thereby reducing the storage effect. Therefore, when the door body of the storage space is confirmed to be closed, whether the evaporator in the air-cooling space is in a defrosting state or not can be further detected, and whether the condensation prevention control is required or not can be further judged.

Of course, the step of detecting whether the evaporator in the first space is in the defrosting state is not necessarily performed after the door body of the second space is confirmed to be closed, but may be performed after the evaporator in the first space is confirmed not to be in the defrosting state, and then the door body of the second space is detected to be closed, and the anti-condensation control is performed when two conditions that the evaporator in the first space is not in the defrosting state and the door body of the second space is in the closing state are simultaneously achieved.

Further, it is also possible to provide only step S90 before step S10, and perform step S10 when the evaporator is not in the defrosting state.

Referring to fig. 14, according to the seventh embodiment of the anti-condensation control method for the refrigerator of the present invention, in the eighth embodiment of the anti-condensation control method for the refrigerator, when the evaporator is not in the defrosting state, the anti-condensation control method for the refrigerator further performs the following steps:

step S100, detecting whether a damper of the second space is opened;

when the damper of the second space is opened, the step S10 is performed: and acquiring current humidity data in the second space.

When the air door of the storage space is not opened, even if the air guide hole is opened, no air enters the storage space from the air cooling space. It is easily understood that, in other embodiments of the present invention, any one of the steps S80, S90, and S100 may be separately provided before the step S10 to become a condition for determining whether to perform the anti-condensation control; alternatively, any two of steps S80, S90, and S100 may be provided before step S10 to be a condition for determining whether to perform the anti-condensation control, and the execution order of the respective steps is not limited. Further, if the steps S80, S90 and S100 are provided before the step S10, the execution order of these three steps may be changed as needed.
