The damper passage 3 has opposite ends connected to the refrigerating chamber 1 and the freezing chamber, respectively. The opposite ends of the damper passageway 3 are a refrigerating air port 31 and a freezing air port 32, respectively, the refrigerating air port 31 is connected to the refrigerating chamber 1, and the freezing air port 32 is connected to the freezing chamber.

The inside of the refrigerator body is provided with a fan, cold air in the refrigerating chamber is conveyed into the air door channel 3 through the rotation of the fan, and is guided into the refrigerating chamber 1 through the air door channel 3, so that the temperature in the refrigerating chamber 1 is reduced, and the temperature in the refrigerating chamber 1 is regulated to be suitable for preserving food.

Note that, since the damper passage 3 of the refrigerator is provided between the refrigerating chamber 1 and the freezing chamber, it is used to communicate the refrigerating chamber 1 and the freezing chamber. A damper is provided in the damper passage 3 to communicate the refrigerating chamber 1 with the freezing chamber by opening the damper. After the damper is opened, the cold energy in the freezing chamber flows into the refrigerating chamber 1 through the damper channel 3 under the drive of the fan.

Because the condensation plate 5 corresponds to the cold storage air port 31, the water vapor in at least part of the air door channels 3 flows through the condensation plate 5 after flowing out of the cold storage air port 31, and is condensed into condensed water on the condensation plate 5 after encountering the condensation plate 5 with relatively cold temperature, and the condensed water is guided into the guide channel 6 through the condensation plate 5, thereby avoiding the increase of the humidity in the cold storage chamber 1, avoiding the unbalance of the temperature and the humidity in the cold storage chamber 1, providing accurate temperature and humidity control for the preservation of food, and simultaneously saving water resources.

In the present embodiment, a humidifier 7 is provided on the cavity wall of the refrigerating chamber 1, and the humidifier 7 is used for humidifying the refrigerating chamber 1. One end of the flow guide channel 6, which is far away from the condensation plate 5, is communicated to the humidifier 7, and the flow guide channel 6 is used for guiding the condensed water on the condensation plate 5 into the humidifier 7.

The refrigerating chamber 1 is provided with a first cavity 2 and a second cavity 21 on the walls.

When the humidifier 7 is disposed outside the cavity wall of the refrigerating chamber 1, one end of the flow guide passage 6 passes through the first cavity hole 2 to be connected to the humidifier 7. When the humidifier 7 is disposed in the first cavity hole 2 of the chamber of the refrigerating chamber 1, one end of the flow guide passage 6 is connected to the humidifier 7.

In some embodiments, a steam hole 711 is provided at one end of the humidifying channel 71 penetrating the second cavity hole 21, the steam hole 711 can scatter the steam generated by the humidifier 7, and the steam generated by the humidifier 7 is diffused into the refrigerating chamber 1 through the steam hole 711 to improve the air humidity in the refrigerating chamber 1.

In some embodiments, the condensation plate 5 is rotatably connected to the diversion channel 6, and a driving motor 8 is disposed on the cavity wall of the refrigerating chamber 1, and the driving motor 8 can be fixedly connected to the cavity wall of the refrigerating chamber 1 through a fastener. The drive motor 8 has a motor output shaft 81, and the motor output shaft 81 is rotatable. By connecting the motor output shaft 81 of the driving motor 8 with the condensation plate 5, the motor output shaft 81 can drive the condensation plate 5 to rotate relative to the diversion channel 6 when the motor output shaft 81 of the driving motor 8 rotates.

When the heating wire 4 is started to heat, the drive motor 8 drives the condensation plate 5 to rotate to a position corresponding to the refrigerating tuyere 31. The heating wire 4 heats condensed water or frosted frost layer condensed at the air door channel 3, the condensed water or frosted frost layer is evaporated into water vapor through heating, the water vapor can flow to the condensation plate 5 corresponding to the refrigeration air opening 31 through the refrigeration air opening 31 under the drive of the fan, the water vapor is condensed into condensed water on the condensation plate 5 after encountering the condensation plate 5 with relatively cold temperature, and the condensed water is guided into the guide channel 6 through the condensation plate 5, thereby avoiding the increase of the humidity in the refrigeration chamber 1, avoiding the unbalance of the temperature and the humidity in the refrigeration chamber 1 and providing accurate temperature and humidity control for the preservation of food.

When the heating wire 4 is turned off for heating, the drive motor 8 drives the condensation plate 5 to rotate in a direction away from the refrigerating tuyere 31. It can be arranged that after the heating wire 4 is closed for heating, the drive motor 8 drives the condensation plate 5 to rotate to a position avoiding the air outlet of the cold storage air inlet 31, so that the condensation plate 5 is vertically arranged, and the blocking of the air outlet of the cold storage air inlet 31 is reduced. And at the same time, the space occupied by the stored articles in the refrigerating chamber 1 can be reduced.

Referring to fig. 10-20, in some embodiments, the motor output shaft 81 is connected to a first gear 9, and the condensation plate 5 is connected to a second gear 91, and the second gear 91 cooperates with the first gear 9 to achieve a meshing transmission.

Referring to fig. 1 to 11, in some embodiments, a first humidity sensor 10 and a second humidity sensor 11 are further provided within the refrigerating compartment 1. The first humidity sensor 10 is disposed near the refrigerating tuyere 31 and is disposed corresponding to the refrigerating tuyere 31. The first humidity sensor 10 is used for detecting the temperature and humidity at the refrigerating tuyere 31 in real time. The second humidity sensor 11 is disposed away from the refrigerating tuyere 31 relative to the first humidity sensor 10, and the second humidity sensor 11 is used for detecting the temperature and humidity in the refrigerating chamber 1 in real time. It may be provided that the second humidity sensor 11 is provided at the middle of the refrigerating compartment 1 in order to make the detected value of the second humidity sensor 11 more representative of the average value of the refrigerating compartment 1.

The heating wire 4 is controlled to be turned on and turned off by the temperature and humidity value detected by the first humidity sensor 10. Because condensation can occur before frosting, if the nearby air door channel 3 is not condensed, the air door air channel can not frost.

The controller stores a database of the mapping relation between the relative humidity detected by the first humidity sensor 10 and the relative temperature, that is, when the relative humidity detected by the first humidity sensor 10 is the first humidity, the second humidity, and the third humidity, the corresponding condensation temperature is the first temperature, the second temperature, and the third temperature, respectively, and the data are pre-stored in the controller.

When the refrigerator starts to operate, the controller acquires the humidity value detected by the first humidity sensor 10 and the temperature value detected by the first humidity sensor 10 at this time. If the temperature value is equal to or smaller than the temperature value under the corresponding humidity, the condensation is possibly caused, and the controller controls the heating wire 4 to start heating at the moment, so that the condensation or frost layer in the air door channel 3 is evaporated. If the temperature value is greater than the temperature value at the corresponding humidity at this time, the heating wire 4 is turned off to stop heating.

In some embodiments, the relative humidity detected by the first humidity sensor 10 and the relative temperature relative thereto are stored in the controller, the relative temperature being provided with a deviation value Δt, and the controller increases or decreases the deviation value Δt on the basis of the relative temperature when the first humidity sensor 10 transmits the detected real-time temperature to the controller.

If the real-time temperature is less than or equal to the relative temperature + -DeltaT, it indicates that condensation is possible, and the controller controls the heating wire 4 to start heating to evaporate the condensation or frost layer in the air door channel 3.

If the real-time temperature is larger than the relative temperature + -delta T, which indicates that the temperature does not reach the condensation temperature at the moment, the controller controls the heating wire 4 to be disconnected to stop heating.

The embodiment provides a refrigerator, a heating device is arranged on an air door channel 3 of the refrigerator, a controller obtains a door frame condensation condition corresponding to the real-time humidity of the current air door channel 3 according to a preset corresponding relation between the real-time humidity and the relative temperature of the current air door channel 3 by obtaining the real-time humidity and the real-time temperature of the current air door channel 3, and judges whether the condensation condition of the air door channel 3 is met currently or not according to the real-time humidity of the air door channel 3 and the real-time temperature of the air door channel 3. If yes, the heating wire 4 is controlled to be in a starting running state; if not, the heating wire 4 is controlled to be in a stop operation state. By adopting the embodiment of the utility model, whether the current air door channel 3 has the condensation phenomenon or not is judged by detecting the real-time humidity and the real-time temperature of the current air door channel 3 in real time so as to control the start and stop of the heating wire 4, thereby heating the air door channel 3 when the condensation occurs so as to evaporate the condensation, avoiding the phenomenon that the air door of the air door channel 3 is frosted and frozen, providing a good running environment for the refrigerator and providing a good refrigerator use experience for users.

In some embodiments, the controller always controls the heater wire 4 to be turned off because of erroneous judgment that may be caused by the failure of the first humidity sensor 10, such that the heater wire 4 is always turned on or the damper passage 3 has frosted but the controller always does not acquire the real-time temperature value detected by the first humidity sensor 10.

Under the worst condition obtained by experimental data, how long the heating wire 4 needs to be started to enable the frost layer to be clean, the time is defined as the first protection time, when the heating wire 4 is started, the time is counted at the same time, if the first protection time is exceeded, the heating wire 4 is forcedly closed, and the air door channel 3 is prevented from being burnt out by long-time dry burning. The air door channel 3 does not need to be opened for heating the heating wire 4 to heat the frostless time under the optimal state tested by experimental data, the frostless time is defined as the second protection time, the controller counts the time when the heating wire 4 is disconnected and stops heating, and if the second protection time is exceeded, the heating wire 4 is forcedly opened to perform forceful defrosting, so that the air door is prevented from being opened for a long time to cause frosting of the air door channel 3 and influence the temperature control of the refrigerating chamber 1.

When the first protection time or the second protection time is reached, the controller counts the fault sign of the first humidity sensor 10 for one time, when the fault sign of the first humidity sensor 10 is counted for three times, the fault of the first humidity sensor 10 is indicated, the controller sends out a warning to remind a user to detect the first humidity sensor 10, after the fault of the first humidity sensor 10 is eliminated, the fault is eliminated when the refrigerator is powered on again, and the refrigerator operates normally again.

In some embodiments, the height of the end of the top plate 511 away from the connection end 52 is higher than the height of the end of the top plate 511 near the connection end 52, and the top plate 511 extends from the end of the top plate 511 away from the connection end 52 to the end of the top plate 511 near the connection end 52, so that the condensed water on the top plate 511 can be guided to the guide channel 6 along the top plate 511 with gradually reduced height, and the condensation on the condensation plate 5 can be prevented from dripping in the refrigerating chamber 1.

In some embodiments, the second gear 91 is connected to the connection end 52 of the condensation plate 5, so that when the driving motor 8 rotates to drive the first gear 9 to rotate, the first gear 9 drives the condensation plate 5 to rotate around the connection end 52 thereof through meshing transmission with the second gear 91, so that when the heating wire 4 is turned on, the condensation plate 5 is rotated to a position corresponding to the refrigerating tuyere 31 to perform condensation, and humidity in the refrigerating chamber 1 is reduced. When the heating wire 4 is disconnected and stops opening, the condensation plate 5 is rotated to a position avoiding the cold storage air port 31, so that air blown out of the cold storage air port 31 is prevented from being blocked, and the storage space is prevented from being occupied.

The humidifier 7 can utilize the condensation plate 5 to guide the condensed water in the humidifier 7 to humidify the refrigerating chamber 1 so as to save water resources and realize the reutilization of the water resources.
