[0055] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0056] Example 1
[0057] In order to meet the user's requirements for the moisture of food ingredients, an independent fruit and vegetable storage compartment is generally set up in the refrigerator, which is specifically used for the preservation of fruits and vegetables. In order to improve the preservation effect, the fruit and vegetable storage compartment will be humidified. However, if the humidity in the fruit and vegetable storage compartment is too high and the temperature is too low, condensation will be produced. Due to the effect of gravity, these condensations will converge into water flows and gather at the bottom of the fruit and vegetable storage compartment. Soaking in water for a long time will accelerate the decay of fruits and vegetables.
[0058] In view of the problem in the prior art that when the humidity in the fruit and vegetable storage compartment of a refrigerator is too high, condensation is easily generated, which accelerates the decay of fruits and vegetables, this embodiment provides a humidity control device, which is applied to the fruit and vegetable storage compartment of the refrigerator. A humidifier is arranged in the fruit and vegetable storage compartment. Figure 1 : is a structural diagram of a humidity control device according to an embodiment of the present invention, Figure 1 As shown, the humidity control device includes: an air inlet door 1, which is connected to the outlet 2 of the air inlet duct of the fruit and vegetable storage compartment; a baffle 3, which is arranged at the outlet 2 of the air inlet duct, and a fan 6 is also arranged in the air inlet duct near the outlet 2 of the air inlet duct; an air outlet door 4, which is connected to the inlet 5 of the air outlet duct of the fruit and vegetable storage compartment; a controller, which connects the air inlet door 1, the baffle 3 and the driving mechanism of the air outlet door 4, the heat exchanger (not shown in the figure) and the humidifier (not shown in the figure) in the air inlet duct, and the controller controls the opening and closing of the air inlet door 1, the opening and closing of the air outlet door 4, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier and the angle of the baffle 3 according to the condensation condition at the bottom of the fruit and vegetable storage compartment and the humidity in the fruit and vegetable storage compartment.
[0059] The operating states of the heat exchanger include cooling and stopping cooling. When the heat exchanger is cooling, the temperature in the fruit and vegetable storage room continues to drop, and the risk of condensation increases. After the humidifier is turned on, the humidity in the fruit and vegetable storage room increases, and the risk of condensation also increases. If the angle of the baffle at the outlet of the air inlet duct is tilted upward, the temperature and humidity can be evenly distributed. If the angle of the baffle is tilted downward, it is conducive to removing condensation. The opening and closing of the air inlet door and the opening and closing of the air outlet door determine the inflow or outflow of gas in the fruit and vegetable storage room, which in turn affects the inflow and outflow of water vapor, thereby affecting the humidity in the fruit and vegetable storage room. In summary, according to the condensation situation at the bottom of the fruit and vegetable storage room and the humidity in the fruit and vegetable storage room, the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle at the outlet of the air inlet duct can be controlled to obtain appropriate humidity, and at the same time, the condensation generated at the bottom of the fruit and vegetable storage room when the humidity is too high can be removed in time.
[0060] The humidity control device of this embodiment is provided with an air inlet door 1 and an air outlet door 4 in the fruit and vegetable storage compartment, the air inlet door 1 is connected to the outlet 2 of the air inlet duct of the fruit and vegetable storage compartment, a baffle is provided at the outlet 2 of the air inlet duct, and the air outlet door 4 is connected to the inlet 5 of the air outlet duct of the fruit and vegetable storage compartment; the controller controls the opening and closing of the air inlet door 1, the opening and closing of the air outlet door 4, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle 3 of the air outlet door according to the condensation condition at the bottom of the fruit and vegetable storage compartment and the humidity in the fruit and vegetable storage compartment, thereby ensuring the humidity of the fruit and vegetable storage compartment and removing the condensation in time, so as to ensure the moisture of the food and prevent the food from being soaked in water and rotting.
[0061] In order to detect the condensation at the bottom of the fruit and vegetable storage compartment so as to remove the condensation in time and prevent the fruits and vegetables from rotting, the above device also includes a condensation detection circuit. Figure 2 is a structural diagram of a condensation detection circuit according to an embodiment of the present invention, as shown in Figure 2 As shown, the condensation detection circuit includes: a first conductive terminal a and a second conductive terminal b, as mentioned above Figure 1 As shown in , the first conductive terminal a and the second conductive terminal b are arranged at intervals at the bottom of the fruit and vegetable storage compartment, as shown in Figure 2 As shown, the first conductive terminal a is connected to a voltage source (+5V), and the second conductive terminal b is grounded through a first resistor R1; the switch tube Q, its control end (G pole) is connected between the first resistor R1 and the second conductive terminal b, its input end (D pole) is connected to the voltage source through a second resistor R2, and its output end (S pole) is grounded; a detection terminal JS is led out between the input end of the switch tube Q and the second resistor R2, and connected to a controller; the controller determines whether condensation occurs at the bottom of the storage compartment according to a voltage signal output by the detection terminal.
[0062] The working principle of the condensation detection circuit of this embodiment is as follows: two conductive terminals are set and installed at the bottom of the fruit and vegetable storage compartment. The first conductive terminal a is connected to the voltage source (+5V), and the second conductive terminal b is grounded through the first resistor R1. When condensation occurs at the bottom of the fruit and vegetable storage compartment, the first conductive terminal a and the second conductive terminal b are immersed in water. The two conductive terminals are connected due to the conductivity of water. The conduction impedance between the two conductive terminals is between several hundred Ω and 1MΩ. After the voltage provided by the 5V voltage source is divided by the first resistor R1, a voltage value is output. The voltage value exceeds the switch tube Q The switch tube Q is turned on, and the 5V voltage provided by the voltage source passes through the second resistor R2 in turn, and the switch tube Q flows to the reference ground, and the detection terminal JS is grounded through the switch tube Q, and the detection terminal JS outputs a low level; when no condensation is generated at the bottom of the fruit and vegetable storage compartment, there is no conduction between the first conductive terminal a and the second conductive terminal b. On the one hand, the voltage provided by the 5V voltage source will not be output to the control end of the switch tube Q, so the switch tube Q is disconnected. On the other hand, the 5V voltage provided by the voltage source passes through the second resistor R2 in turn and flows to the detection terminal JS, and the detection terminal JS outputs a high level. The detection terminal JS is connected to the controller, and the changes in the high and low levels are fed back to the mainboard of the controller.
[0063] Based on the above principle, the controller is specifically used to: when the voltage signal output by the detection terminal JS is at a high level, determine that no condensation is generated at the bottom of the fruit and vegetable storage compartment; when the voltage signal output by the detection terminal JS is at a low level, determine that condensation is generated at the bottom of the fruit and vegetable storage compartment.
[0064] In order to filter the voltage output by the voltage source, the condensation detection circuit further includes: a third resistor R3, which is arranged between the control end of the switch tube Q and the second conductive terminal b; a first capacitor C1, whose first end is connected between the third resistor R3 and the control end of the switch tube Q, and whose second end is grounded; the third resistor R3 and the first capacitor C1 form an RC filter circuit to filter the voltage output by the voltage source. In addition, the third resistor R3 also has a voltage limiting function, which can limit the voltage input to the control end of the switch tube Q.
[0065] In order to filter the voltage at the input end of the switch tube Q, the condensation detection circuit further includes: a second capacitor C2, a first end of which is connected to the input end of the switch tube Q, and a second end of which is grounded.
[0066] Example 2
[0067] This embodiment provides a refrigerator, including a fruit and vegetable storage compartment, and also includes the humidity control device of the above embodiment.
[0068] Example 3
[0069] This embodiment provides a humidity control method, which is applied to the humidity control device of the above embodiment. Figure 3 : is a flow chart of a humidity control method according to an embodiment of the present invention. Figure 3 As shown, the humidity control method includes:
[0070] S101, obtaining the condensation condition at the bottom of the fruit and vegetable storage room and the humidity inside the fruit and vegetable storage room.
[0071] In specific implementation, the condensation at the bottom of the fruit and vegetable storage compartment can be detected by the condensation detection circuit, and a humidity sensor can be arranged inside the fruit and vegetable storage compartment to detect the humidity inside the fruit and vegetable storage compartment.
[0072] S102, controlling the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle at the outlet of the air inlet duct according to the condensation condition at the bottom of the fruit and vegetable storage room and the humidity inside the fruit and vegetable storage room.
[0073] The operating states of the heat exchanger include cooling and stopping cooling. When the heat exchanger is cooling, the temperature in the fruit and vegetable storage room continues to drop, and the risk of condensation increases. After the humidifier is turned on, the humidity in the fruit and vegetable storage room increases, and the risk of condensation also increases. If the angle of the baffle at the outlet of the air inlet duct is tilted upward, the temperature and humidity can be evenly distributed. If the angle of the baffle is tilted downward, it is conducive to removing condensation. The opening and closing of the air inlet door and the opening and closing of the air outlet door determine the inflow or outflow of gas in the fruit and vegetable storage room, which in turn affects the inflow and outflow of water vapor, thereby affecting the humidity in the fruit and vegetable storage room. In summary, according to the condensation situation at the bottom of the fruit and vegetable storage room and the humidity in the fruit and vegetable storage room, the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle at the outlet of the air inlet duct can be controlled to obtain appropriate humidity, and at the same time, the condensation generated at the bottom of the fruit and vegetable storage room when the humidity is too high can be removed in time.
[0074] The humidity control method of this embodiment controls the opening and closing of the air inlet door and the air outlet door of the fruit and vegetable storage compartment, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle of the air outlet door according to the condensation at the bottom of the fruit and vegetable storage compartment and the humidity inside the fruit and vegetable storage compartment, thereby ensuring the humidity of the fruit and vegetable storage compartment and removing the condensation in time, thereby ensuring the freshness of the food stored in the refrigerator and preventing the food from being soaked in water and rotting.
[0075] If there is no condensation at the bottom of the fruit and vegetable storage room, the risk of fruit and vegetable rotting and deterioration is low. At this time, the humidity in the fruit and vegetable storage room should be guaranteed based on the need for freshness preservation. However, if condensation is generated at the bottom of the fruit and vegetable storage room, the risk of fruit and vegetable rotting and deterioration is high. At this time, the need for anti-rot should be given priority, and the condensation at the bottom of the fruit and vegetable storage room should be cleared first. Therefore, according to the condensation at the bottom of the fruit and vegetable storage room and the humidity in the fruit and vegetable storage room, the opening and closing of the air inlet door, the opening and closing of the air outlet door, and the operation of the heat exchanger in the air inlet duct should be controlled. The method comprises: judging whether condensation is generated at the bottom of the fruit and vegetable storage room; if so, controlling the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle according to the first control strategy according to the humidity in the fruit and vegetable storage room; if not, controlling the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle according to the second control strategy according to the humidity in the fruit and vegetable storage room.
[0076] Specifically, according to the humidity in the fruit and vegetable storage room, the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle are controlled according to the first control strategy, including: judging whether the humidity reaches a preset threshold value; if yes, it indicates that condensation is generated at the bottom of the fruit and vegetable storage room, and the humidity in the fruit and vegetable storage room is relatively high. At this time, the air inlet door is controlled to be opened, the air outlet door is controlled to be opened, the heat exchanger is controlled to stop cooling, the humidifier is controlled to be closed, and the baffle is controlled to tilt downward, so as to promote the condensation at the bottom of the fruit and vegetable storage room to evaporate as soon as possible, and take away the evaporated water vapor in time through the air outlet door; if no, it indicates that condensation is generated at the bottom of the fruit and vegetable storage room, and the humidity in the fruit and vegetable storage room is relatively low, and it is only necessary to control the condensation at the bottom of the fruit and vegetable storage room to evaporate into the air in the fruit and vegetable storage room as soon as possible, so the air inlet door is controlled to be closed, the air outlet door is controlled to be closed, the heat exchanger is controlled to stop cooling, the humidifier is controlled to be closed, and the baffle is controlled to tilt downward.
[0077] Specifically, according to the humidity in the fruit and vegetable storage room, the opening and closing of the air inlet door, the opening and closing of the air outlet door, the operating state of the heat exchanger in the air inlet duct, the opening and closing of the humidifier, and the angle of the baffle are controlled according to the second control strategy, including: judging whether the humidity reaches a preset threshold value; if yes, it indicates that no condensation is generated at the bottom of the fruit and vegetable storage room, but the humidity in the fruit and vegetable storage room is relatively high, and the air inlet door is controlled to be opened, the air outlet door is controlled to be opened, the heat exchanger is controlled to stop cooling, the humidifier is controlled to be closed, and the baffle is controlled to tilt upward to dehumidify by blowing normal temperature air; if no, it indicates that no condensation is generated at the bottom of the fruit and vegetable storage room, and the humidity in the fruit and vegetable storage room is relatively high, and the air inlet door is controlled to be opened, the air outlet door is controlled to be opened, the heat exchanger is controlled to cool, the humidifier is controlled to be opened, and the baffle is controlled to tilt upward to increase the humidity in the fruit and vegetable storage room.
[0078] Example 4
[0079] This embodiment provides another humidity control method. Figure 4 is a flow chart of a humidity control method according to another embodiment of the present invention. Figure 4 As shown, the humidity control method includes:
[0080] S1, after the refrigerator detects that fruits and vegetables are placed in the fruit and vegetable storage compartment, the fan starts working, blowing cold air for humidification and controlling the baffle to tilt upward to ensure that the cold air blows upward.
[0081] Blowing cold air upwards prevents uneven temperature and the bottom temperature from being too low.
[0082] S2, controls the condensation detection circuit and controls the humidity sensor to start.
[0083] S3, determining whether condensation is generated at the bottom of the fruit and vegetable storage compartment, if yes, executing step S4, if no, executing step S7.
[0084] S4, determining whether the humidity of the fruit and vegetable storage compartment reaches a preset threshold; if yes, executing step S5, if no, executing step S6.
[0085] S5, controls the heat exchanger to stop cooling, the humidifier to stop humidifying, controls the air inlet door and the air outlet door to remain open, and controls the baffle to tilt downward.
[0086] Through the above operation, it is ensured that the wind blows toward the bottom of the fruit and vegetable storage room to speed up the removal of condensation. At this time, the fan blows normal temperature air to remove condensation and dehumidify, and takes away water vapor through the air outlet.
[0087] S6, controls the heat exchanger to stop cooling, the humidifier to stop humidifying, controls the air inlet door and the air outlet door to close, and controls the baffle to tilt downward.
[0088] The air inlet and outlet doors are controlled to be closed to prevent the humidity from decreasing when the air is exchanged with the outside air. The baffle is controlled to tilt downward to ensure that the wind blows to the bottom to accelerate the removal of condensation. At this time, the fan blows normal temperature air to remove condensation but does not dehumidify.
[0089] S7, determining whether the humidity of the fruit and vegetable storage compartment reaches a preset threshold; if yes, executing step S8, if no, executing step S9.
[0090] S8, controls the heat exchanger to stop cooling, the humidifier to stop humidifying, the air inlet door and the air outlet door to remain open, and controls the baffle to tilt upward.
[0091] Through the above operation, the fan can blow normal temperature air for dehumidification.
[0092] S9, controls the heat exchanger to cool, the humidifier to humidify, the air inlet door and the air outlet door to remain open, and controls the baffle to tilt upward.
[0093] Through the above operations, refrigeration and humidification are achieved.
