[0002] According to the air circulation mode, refrigerators are generally divided into direct cooling refrigerators and air-cooling refrigerators. Air-cooling refrigerators use fans to blow cold air generated by the refrigeration system into the refrigeration chamber to cool the food in the refrigeration chamber. In order to solve the problem of drying caused by cold air blowing towards the food, air-cooling refrigerators are usually equipped with a humidifying device for humidifying the refrigeration chamber to increase the humidity in the refrigeration chamber.

[0003] In the related art, the humidifier is usually provided with a water storage part for storing water, and the user is required to regularly add water to the water storage part to ensure the humidification function of the humidifier. However, when the water in the water storage part is exhausted and the user forgets to add water to the water storage part, the humidification function of the humidifier will fail. Summary of the invention

[0004] The embodiment of the present application provides a refrigerator and a control method thereof, which can solve the technical problem that when the water in the water storage part is exhausted and the user forgets to add water to the water storage part, the humidification function of the humidification device will fail.

[0007] A door body, connected to the box body, used to open or close the access opening;

[0008] A humidifying device, comprising a water storage member for storing water, the humidifying device being further configured to make the water in the water storage member form water vapor and release it into the refrigeration chamber;

[0009] An air water extraction device, comprising:

[0010] A second shell body connected to the box body or the door body and having a second accommodating cavity, wherein the second shell body is provided with a first air inlet and a first air outlet connected to the second accommodating cavity, and the bottom of the second shell body is connected to the water storage member;

[0011] A driving fan, which is disposed in the second accommodating chamber and is configured to allow external air to enter the second accommodating chamber through the first air inlet and flow out through the first air outlet to form a water intake airflow;

[0012] A semiconductor refrigeration sheet is arranged in the second accommodating cavity, and has a cooling end and a heat dissipation end opposite to each other. The cooling end is in contact with the water intake air flow so that the moisture in the water intake air flow condenses at the cooling end and falls into the bottom of the second shell and then flows into the water storage member.

[0013] The refrigerator of the embodiment of the present application is provided with an air water intake device, which includes a second shell, a driving fan and a semiconductor refrigeration plate. The second shell is connected to the outside through the first air inlet and the first air outlet. The driving fan and the semiconductor refrigeration plate are located in the second shell. The driving fan drives the external air to enter the second shell through the first air inlet and flow out from the first air outlet to form a water intake airflow. The cooling end of the semiconductor refrigeration plate is in contact with the water intake airflow, which can condense the water vapor in the water intake airflow to form water droplets, and slide to the bottom of the second shell, and then flow into the water storage part to add water to the water storage part for use by the humidification device. Even if the user forgets to add water to the water storage part, the humidification function of the humidification device can be guaranteed.

[0014] In some embodiments of the application, the semiconductor refrigeration plate is vertically arranged in the second accommodating cavity, a top air duct is formed between the semiconductor refrigeration plate and the inner top wall of the second shell, and the driving fan is located in the top air duct; the refrigeration end and the second shell are surrounded by a refrigeration air duct, and the first air inlet is connected to the refrigeration air duct; the heat dissipation end and the second shell are surrounded by a heat dissipation air duct, and the heat dissipation air duct is connected to the refrigeration air duct through the top air duct, and the first air outlet is connected to the heat dissipation air duct; the water intake air flow flows through the refrigeration air duct, the top air duct and the heat dissipation air duct in sequence.

[0015] In this arrangement, the cooling end of the semiconductor refrigeration sheet is located in the cooling air duct, and the heating end is located in the heat dissipation air duct. When the water intake air flow flows through the cooling air duct, the water vapor in the water intake air flow condenses when it encounters cold, so that the temperature of the water intake air flow decreases. When the water intake air flow further flows through the heat dissipation air duct, the heat dissipation end can be cooled, thereby enhancing the heat dissipation effect of the heat dissipation end, thereby reducing or eliminating the influence of the heat dissipation end of the semiconductor refrigeration sheet on the refrigeration effect of the refrigerator.

[0016] In some embodiments of the present application, the second shell includes a accommodating portion, and an air inlet portion and an air outlet portion, the accommodating portion is constructed with the second accommodating cavity, and a second air inlet and a second air outlet are respectively provided on both sides of the bottom of the accommodating portion, the second air inlet is communicated with the refrigeration air duct, and the second air outlet is communicated with the heat dissipation air duct; the air inlet portion is connected to the accommodating portion, an air inlet channel is formed in the air inlet portion, a first end of the air inlet channel is the first air inlet, and a second end of the air inlet channel is connected to the second air inlet; the air outlet portion is connected to the accommodating portion, an air outlet channel is formed in the air outlet portion, a first end of the air outlet channel is the first air outlet, and a second end of the air outlet channel is connected to the second air outlet.

[0017] In this arrangement, the external air enters the air inlet channel through the first air inlet, enters the accommodating portion through the third air inlet, enters the air outlet channel through the third air outlet, and then flows out from the first air outlet to form a water intake airflow. Compared with the accommodating portion, the aperture size of the air inlet channel and the air outlet channel is smaller, which can increase the flow rate of the water intake airflow, thereby increasing the renewal speed of the air in the accommodating portion, thereby increasing the amount of water condensed on the refrigeration end, and improving the water intake efficiency of the air water intake device.

[0019] With such an arrangement, water droplets condensed at the refrigeration end can fall into the water collecting trough, which can collect water. The collected water can enter the connecting pipe through the water outlet and enter the water storage member along the connecting pipe, which can increase the amount of water entering the water storage member, thereby further ensuring the humidification function of the humidification device.

[0020] In some embodiments of the present application, the distance between two opposite groove walls in the water receiving groove gradually increases in the vertical upward direction.

[0021] With such arrangement, the two opposite side groove walls of the water receiving trough are inclined relative to the vertical center line of the water receiving trough, and the two groove walls can guide water so that the water can flow to the bottom of the water receiving trough, thereby improving the water collection efficiency of the water receiving trough.

[0023] In this way, external air can enter the second accommodating cavity of the second shell through the third air inlet and the first air outlet, and flow out of the second accommodating cavity through the third air outlet and the first air outlet to form a water intake airflow, thereby ensuring the water intake effect of the air water intake device. In addition, the second shell is arranged in the door body and is wrapped by the foaming layer, which reduces the influence of the air water intake device on the refrigeration effect of the refrigerator.

[0024] In some embodiments of the present application, the cooling end faces the inner tank, and the heat dissipation end faces the outer shell.

[0095] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0096] refer to Figure 1 The refrigerator of the embodiment of the present application may include a refrigerator body and a humidifying device 300. The refrigerator body is configured with at least one refrigerating chamber, and the refrigerating chamber is used to place food. The humidifying device 300 is connected to the refrigerator body. The humidifying device 300 is provided with a water storage member 320 for storing water. The humidifying device 300 can make the water in the water storage member 320 form water vapor and release it into the refrigerating chamber to increase the humidity in the refrigerating chamber, prevent the food in the refrigerating chamber from drying out, and enhance the food preservation effect.

[0097] Exemplarily, the refrigerator body may include a cabinet 100 and a door 200. The cabinet 100 may be configured with at least one refrigeration chamber having an access opening. The door 200 is connected to the cabinet 100 and is used to open or close the access opening. For example, the door 200 may be connected to a side of the cabinet 100 where the access opening is provided by a hinge, and the door 200 may rotate relative to the cabinet 100, and the access opening may be opened or closed by rotating the door 200. Figure 1 As shown, there may be multiple refrigeration chambers, and each refrigeration chamber may be provided with a corresponding door body 200. In some implementations of the embodiment of the present application, multiple refrigeration chambers may also be provided with a corresponding door body 200.

[0098] The humidifying device 300 is disposed in the refrigerator body, for example, the humidifying device 300 can be disposed in the refrigeration chamber of the cabinet 100. Figure 2 The humidifying device 300 may also be connected to the door body 200 to avoid occupying the space for placing food.

[0099] For example, reference Figure 3 , Figure 4 and Figure 5 The humidifying device 300 may include a first shell 310, and a water storage member 320 and an atomizing assembly 330 located in the first shell 310. The first shell 310 may be connected to the housing 100 or the door 200. For example, the first shell 310 may be connected to the door 200 via a connecting frame 314. The first shell 310 is configured with a first accommodating cavity. The first shell 310 may be a detachably connected split structure so that the first shell 310 can be opened and closed, thereby facilitating the installation of components in the first shell 310.

[0100] The water storage member 320 may include a water storage box 321 and a water storage bottle 322. The capacity of the water storage bottle 322 may be greater than that of the water storage box 321. The top of the water storage box 321 has an opening and may be mounted on the inner bottom wall of the first housing 310. A mounting portion 323 may be provided in the water storage box 321. The water storage bottle 322 may be inverted and detachably inserted in the mounting portion 323. The mounting portion 323 is configured to allow the water in the water storage bottle 322 to flow into the water storage box 321 when the amount of water in the water storage box 321 decreases, so as to replenish the water in the water storage box 321. There is no need to frequently add water to the water storage box 321, thereby improving the convenience of the humidifier 300 when in use. When the water in the water box 321 and the water bottle 322 is exhausted, the user can first open the first shell 310, remove the water bottle 322 from the mounting portion 323, add water to the water bottle 322, and then install the water bottle 322 on the mounting portion 323.

[0101] The atomizing assembly 330 is used to convert the water in the water storage member 320 into water vapor and release it into the refrigeration chamber. For example, the atomizing type of the atomizing assembly 330 can be blowing atomization. Figure 5 , the atomizing fan 331 can be arranged above the water storage bottle 322, and an air inlet 311 can be arranged in the area of ​​the top wall of the first shell 310 opposite to the atomizing fan 331. A drainage air duct 312 can also be arranged in the first shell 310, and the air inlet 311 of the drainage air duct 312 is opposite to the air outlet direction of the atomizing fan 331, and the side wall of the drainage air duct 312 is also provided with an air outlet 313 connected to the refrigeration chamber. The airflow generated by the atomizing fan 331 can enter the drainage air duct 312 through the air inlet 311, and then flow out from the air outlet 313 to form an atomizing airflow, thereby improving the atomization efficiency. For example Figure 5 As shown, the direction indicated by the dotted arrow is the flow direction of the atomized airflow. The bottom of the water absorbent 332 can be inserted into the water storage box 321 to contact the water in the water storage box 321, thereby absorbing the water. The water absorbent 332 itself has a diffusion effect, and the water absorbed by the bottom of the water absorbent 332 can be diffused to other parts of the water absorbent 332. Exemplarily, the material of the water absorbent 332 can be absorbent fiber or absorbent cotton. Part of the water absorbent 332 can extend into the drainage air duct 312 so that the water absorbent 332 is inserted in the atomized airflow. The atomized airflow can flow through the water absorbent 332, and take away the moisture in the water absorbent 332, and release it into the refrigeration chamber through the air outlet 313.

[0102] In some implementations of the embodiments of the present application, reference is made to Figure 6 and Figure 7 The atomizing device may also be provided with an electrolytic water component 340, which is used to electrolyze the water in the water storage box 321. The electrolytic water component 340 may be connected to the water storage box 321 via a water pipe 341. The electrolyzed water is atomized by the atomizing component 330 and then released into the refrigeration chamber, which can sterilize the refrigeration chamber and is beneficial to enhancing the preservation effect of food.

[0103] In some implementations of the embodiments of the present application, the atomization type of the atomization component 330 may also be ultrasonic atomization, which will not be described in detail here.

[0104] Exemplarily, the humidifying device 300 may further include an ion sterilization component 350, which is disposed in the drainage air duct 312, and the atomized airflow may flow through the ion sterilization device. The ion sterilization component 350 may generate charged water molecules, positive and negative ions, or hydroxyl free radicals and other action factors, and the atomized airflow may bring the action factors into the refrigeration chamber to sterilize or deodorize the refrigeration chamber, thereby improving the freshness-keeping performance of the refrigerator.

[0105] refer to Figure 8 and Fig. 9 , the refrigerator of the embodiment of the present application may further include an air water intake device 400. The air water intake device 400 may be connected to the refrigerator body and communicated with the water storage member 320 of the humidifying device 300. The air water intake device 400 is configured to obtain moisture from the air and store it in the water storage member 320 for use by the humidifying device 300. By providing the air water intake device 400 to obtain moisture from the air and store the moisture in the water storage member 320 of the humidifying device 300 for use by the humidifying device 300, even if the user forgets to add water to the water storage member 320, the humidifying function of the humidifying device 300 can be guaranteed.

[0106] For example, reference Fig.10 , Fig.11 , Fig.12 and Fig.13 The air water intake device 400 may include a second shell 410, a driving fan 420 and a semiconductor refrigeration sheet 430. The second shell 410 is connected to the box body 100 or the door body 200, and is configured with a second accommodating cavity. The second shell 410 is provided with a first air inlet 411 and a first air outlet 412 connected to the second accommodating cavity, and the bottom of the second shell 410 is connected to the water storage member 320. The driving fan 420 is disposed in the second accommodating cavity, and is configured to allow external air to enter the second accommodating cavity through the first air inlet 411 and flow out through the first air outlet 412 to form a water intake airflow. For example Fig.12 and Fig.13 As shown, the direction indicated by the dotted arrow is the flow direction of the water intake airflow. The semiconductor cooling sheet 430 is arranged in the second accommodating cavity, and the semiconductor cooling sheet 430 has a cooling end and a heat dissipation end opposite to each other. The cooling end contacts the water intake airflow, so that the water in the water intake airflow condenses at the cooling end and falls into the bottom of the second shell 410 and then flows into the water storage member 320.

[0107] The refrigerator of the embodiment of the present application is provided with an air water intake device 400, and the air water intake device 400 includes a second shell 410, a driving fan 420 and a semiconductor cooling sheet 430. The second shell 410 is connected to the outside through a first air inlet 411 and a first air outlet 412. The driving fan 420 and the semiconductor cooling sheet 430 are located in the second shell 410. The driving fan 420 drives the external air to enter the second shell 410 through the first air inlet 411, and flows out from the first air outlet 412 to form a water intake airflow. The cooling end of the semiconductor cooling sheet 430 contacts the water intake airflow, which can condense the water vapor in the water intake airflow to form water droplets, and slide to the bottom of the second shell 410, and then flow into the water storage part 320, so as to add water to the water storage part 320 for use by the humidification device 300. Even if the user forgets to add water to the water storage part 320, the humidification function of the humidification device 300 can be guaranteed.

[0108] The second housing 410 is used to provide a space for accommodating and installing other components of the air water intake device 400. Fig.12 and Fig.13 , and combined with Fig.14 , Fig.15 , Fig.16 and Fig.17 , the semiconductor cooling sheet 430 can be arranged vertically in the second accommodating cavity, and a top air duct 413 is formed between the semiconductor cooling sheet 430 and the inner top wall of the second shell 410, and the driving fan 420 can be located in the top air duct 413. The cooling end and the second shell 410 are surrounded by a cooling air duct 414, and the first air inlet 411 is connected to the cooling air duct 414. The heat dissipation end and the second shell 410 are surrounded by a heat dissipation air duct 415, and the heat dissipation air duct 415 is connected to the cooling air duct 414 through the top air duct 413, and the first air outlet 412 is connected to the heat dissipation air duct 415. The water intake air flow flows through the cooling air duct 414, the top air duct 413 and the heat dissipation air duct 415 in sequence. The cooling end of the semiconductor cooling sheet 430 is located in the cooling air duct 414, and the heating end is located in the heat dissipation air duct 415. When the water intake air flow flows through the cooling air duct 414, the water vapor in the water intake air flow condenses when it encounters cold, so that the temperature of the water intake air flow is reduced. When the water intake air flow further flows through the heat dissipation duct 415, it can cool the heat dissipation end, thereby enhancing the heat dissipation effect of the heat dissipation end, thereby reducing or eliminating the influence of the heat dissipation end of the semiconductor refrigeration plate 430 on the refrigeration effect of the refrigerator.

[0109] For example, reference Figures 14 to 16The second housing 410 may include a housing portion 417, an air inlet portion 418 and an air outlet portion 419. The housing portion 417 is configured with a second housing cavity, and a second air inlet 4171 and a second air outlet 4172 are respectively provided on both sides of the bottom of the housing portion 417. The second air inlet 4171 is communicated with the cooling air duct 414, and the second air outlet 4172 is communicated with the heat dissipation air duct 415. The air inlet portion 418 is connected to the housing portion 417, and an air inlet channel 4181 is formed in the air inlet portion 418. The first end of the air inlet channel 4181 is the first air inlet 411, and the second end of the air inlet channel 4181 is connected to the second air inlet 4171. The air outlet portion 419 is connected to the housing portion 417, and an air outlet channel 4191 is formed in the air outlet portion 419. The first end of the air outlet channel 4191 is the first air outlet 412, and the second end of the air outlet channel 4191 is connected to the second air outlet 4172. External air can enter the air inlet channel 4181 through the first air inlet 411, enter the accommodating portion 417 through the third air inlet 221, enter the air outlet channel 4191 through the third air outlet 222, and then flow out from the first air outlet 412 to form a water intake airflow. Compared with the accommodating portion 417, the aperture size of the air inlet channel 4181 and the air outlet channel 4191 is smaller, which can increase the flow rate of the water intake airflow, thereby increasing the renewal speed of the air in the accommodating portion 417, thereby increasing the amount of water condensed at the refrigeration end, and improving the water intake efficiency of the air water intake device 400.

[0110] The inner bottom side of the second shell 410 may be provided with a water receiving groove 4173, the water receiving groove 4173 is located below the cooling air duct 414, and the bottom of the water receiving groove 4173 is provided with a water outlet 4174, and the water outlet 4174 is located above the water storage member 320. The air water intake device 400 also includes a connecting pipe 440, and the connecting pipe 440 connects the water outlet 4174 and the water storage member 320. Water droplets condensed at the cooling end may fall into the water receiving groove 4173, and the water receiving groove 4173 may collect water. The collected water may enter the connecting pipe 440 through the water outlet 4174 and enter the water storage member 320 along the connecting pipe 440, which may increase the amount of water entering the water storage member 320, thereby further ensuring the humidification function of the humidification device 300.

[0111] The distance between the two opposite groove walls in the water receiving groove 4173 can be gradually increased in the vertical upward direction. In other words, the groove walls on both sides of the water receiving groove 4173 are inclined relative to the vertical center line of the water receiving groove 4173, and the two groove walls can guide the water so that the water can flow to the bottom of the water receiving groove 4173, thereby improving the water collection efficiency of the water receiving groove 4173.

[0112] refer to Figure 2 and Figure 6The door body 200 may include an outer shell 220 and an inner liner 210 connected to each other, the outer shell 220 and the inner liner 210 are arranged to form a third accommodating chamber, the outer shell 220 is connected to the box body 100, and the outer shell 220 is provided with a third air inlet 221 and a third air outlet 222 connected to the third accommodating chamber. The second shell 410 is located in the third accommodating chamber, the first air inlet 411 of the second shell 410 is connected to the third air inlet 221, and the first air outlet 412 of the second shell 410 is connected to the third air outlet 222. The door body 200 also includes a foaming layer, which is filled in at least part of the space of the third accommodating chamber not occupied by the second shell 410. External air can enter the second accommodating chamber of the second shell 410 through the third air inlet 221 and the first air outlet 412, and flow out of the second accommodating chamber through the third air outlet 222 and the first air outlet 412 to form a water intake airflow, thereby ensuring the water intake effect of the air water intake device 400. Moreover, the second shell 410 is arranged in the door body 200 and is wrapped by the foam layer, which reduces the influence of the air water intake device 400 on the refrigeration effect of the refrigerator.

[0113] Exemplarily, the cooling end faces the inner tank 210, and the heat dissipation end faces the outer shell 220. The cooling end faces the inner tank 210, and the cold energy generated by the cooling end can be released to the inner tank 210 and the refrigeration chamber. The heat dissipation end faces the shell, and the heat generated by the heat dissipation end can be dissipated through the outer shell 220, further reducing the influence of the air water intake device 400 on the refrigeration effect of the refrigerator.

[0114] refer to Fig.12 and Fig.18 The air water intake device 400 further includes a condensing fin 431 and a heat dissipation fin 432. The condensing fin 431 is connected to the cooling end, and the heat dissipation fin 432 is connected to the heat dissipation end. The condensing fin 431 and the heat dissipation fin 432 are both inserted in the water intake airflow. The cooling end can contact the water intake airflow through the condensing fin 431, and the heat dissipation end can contact the water intake airflow through the heat dissipation fin 432, which increases the contact area between the cooling end and the heat dissipation end and the water intake airflow, thereby enhancing the condensation effect of the cooling end and the heat dissipation effect of the heat dissipation end.

[0115] refer to Fig.19 The refrigerator of the embodiment of the present application may further include a controller 500, which may be electrically connected to the humidifying device 300 and the air water intake device 400 to control the humidifying device 300 and the air water intake device 400. Exemplarily, the refrigerator may further include a humidity sensor 510 and a liquid level sensor 520. The humidity sensor 510 may be installed in the refrigeration chamber to measure the humidity in the refrigeration chamber. The humidity sensor 510 may be electrically connected to the controller 500, and the controller 500 may obtain the humidity value measured by the humidity sensor 510.

[0116] Exemplarily, the refrigerator may further include a liquid level sensor 520, which is used to detect the liquid level in the water storage box 321. The liquid level sensor 520 may be electrically connected to the controller 500, and the controller 500 may obtain the humidity value measured by the liquid level sensor 520.

[0117] refer to Fig. 20 The embodiment of the present application also provides a refrigerator control method, which is applied to the refrigerator as described above, and the method comprises the following steps:

[0118] S110, obtaining a first liquid level height of a water storage element in the humidification device.

[0119] For example, the controller 500 may control the liquid level sensor 520 to measure a first liquid level height in the water storage box 321 .

[0120] S120: If the first liquid level is lower than the first liquid level preset value, generate a first control signal and a second control signal.

[0121] The controller 500 can obtain the first liquid level height and determine the first liquid level height. If the first liquid level height is lower than the first liquid level preset value, it can be determined that the water in the water storage box 321 is exhausted. The controller 500 generates a first control signal and a second control signal.

[0122] S130, sending a first control signal to the semiconductor refrigeration plate, and sending a second control signal to the driving fan, the first control signal is used to instruct the semiconductor refrigeration plate of the air water intake device to operate, and the second control signal is used to instruct the driving fan of the air water intake device to operate.

[0123] After the controller 500 generates the first control signal, it sends the first control signal to the semiconductor cooling chip 430. The first control signal can be used to instruct the semiconductor cooling chip 430 of the air water intake device 400 to operate. After receiving the first control signal, the semiconductor cooling chip 430 starts to operate.

[0124] After the controller 500 generates the second control signal, it sends the second control signal to the driving fan 420, and the second control signal is used to instruct the driving fan 420 of the air water intake device 400 to operate. After receiving the second control signal, the driving fan 420 starts to be powered on and operates together with the semiconductor cooling sheet 430, so that the air water intake device 400 can obtain moisture from the air.

[0125] The method of the embodiment of the present application determines whether the water in the water storage part 320 is exhausted by obtaining the liquid level height in the water storage part 320. If exhausted, the semiconductor refrigeration plate 430 and the driving fan 420 are instructed to operate to start the air water intake device 400 to obtain moisture from the air for use by the humidification device 300. Even if the user forgets to add water to the water storage part 320, the humidification function of the humidification device 300 can be guaranteed.

[0126] In some implementations of the embodiments of the present application, reference is made to Fig.21 , the refrigerator control method may include the following steps:

[0127] S210, the refrigerator is powered on and operates.

[0128] Connect the refrigerator to a power source and turn on power to the refrigerator.

[0129] S220, detecting whether the liquid level in the water storage box is lower than a first liquid level preset value.

[0130] The controller 500 can control the liquid level sensor 520 to measure the first liquid level in the water storage box 321. The controller 500 obtains the first liquid level and determines whether the first liquid level is lower than the first liquid level preset value. The first liquid level preset value can be used as a threshold to determine whether the water in the water storage box 321 is exhausted.

[0131] S230, if the liquid level in the water storage box is lower than the first liquid level preset value, stop the humidification device, and start the air water intake device to run for a first time period;

[0132] If the controller 500 determines that the first liquid level height is lower than the first liquid level preset value, it is determined that the water in the water storage box 321 is exhausted, and the humidification device 300 is stopped, and the air water intake device 400 is started to run for a first time period. Exemplarily, the controller 500 can send a first control signal to the semiconductor cooling plate 430 of the air water intake device 400, and send a second control signal to the driving fan 420 of the air water intake device 400 to control the operation of the semiconductor cooling plate 430 and the driving fan 420, so as to perform air water intake.

[0133] S240, detecting whether the liquid level in the water storage box is higher than or equal to a second liquid level preset value, and the second liquid level preset value is greater than the first liquid level preset value.

[0134] After the air water intake device 400 runs for the first time, the controller 500 can control the liquid level sensor 520 to measure the liquid level of the water storage box 321 again to obtain a second liquid level height. The controller 500 determines the second liquid level height to determine whether the second liquid level height reaches the second liquid level preset value. The second liquid level preset value can be greater than the first liquid level preset value. The second liquid level preset value can be used as a threshold for determining whether the water in the water storage box 321 is full.

[0135] S250: If the liquid level in the water storage box is higher than or equal to the second liquid level preset value, the operation ends.

[0136] If the second liquid level reaches the second liquid level preset value, it is determined that the water in the water storage box 321 is full. The controller 500 can send a stop instruction to the air water intake device 400 to instruct the semiconductor cooling plate 430 and the driving fan 420 of the air water intake device 400 to stop running.

[0137] S260: If the liquid level in the water storage box is lower than the second liquid level preset value, remind the user to add water.

[0138] If the second liquid level height does not reach the second liquid level preset value, it is determined that the water in the water storage box 321 is not full. The controller 500 can generate a reminder signal to remind the user to add water to the water storage bottle 322, thereby adding water to the water storage box 321.

[0139] Exemplarily, after reminding the user to add water, steps S220 to S240 may be repeatedly performed until the water in the water storage box 321 is filled, and the operation of the air water intake device 400 is stopped.

[0140] In some other implementations of the embodiments of the present application, reference is made to Fig. 22 , the refrigerator control method may include the following steps:

[0141] S310, the refrigerator is powered on and operates.

[0142] Connect the refrigerator to a power source and turn on power to the refrigerator.

[0143] S320: Detect whether the humidity in the refrigeration chamber is less than a preset humidity.

[0144] The controller 500 can control the humidity sensor 510 to measure the humidity in the refrigeration chamber and obtain a humidity value. The controller 500 obtains the humidity value and determines whether the humidity value is less than a preset humidity. The preset humidity can be used as a threshold value for determining whether the humidity in the refrigeration chamber is low. If the humidity value is less than the preset humidity, it is determined that the humidity in the refrigeration chamber is low. If the humidity value is greater than the preset humidity, it is determined that the humidity in the refrigeration chamber is sufficient.

[0145] S330: If the humidity in the refrigeration chamber is lower than the preset humidity, detect whether the door of the refrigerator is opened.

[0146] If the controller 500 determines that the humidity value is less than the preset humidity, it determines that the humidity in the refrigeration chamber is low.

[0147] After determining that the humidity value of the refrigeration chamber is less than the preset humidity, the controller 500 may obtain information on whether the door 200 is opened. Exemplarily, the refrigerator may further include a memory, and the information on whether the door 200 is opened may be stored in the memory. The controller 500 may obtain information on whether the door 200 is opened in the memory to detect whether the door 200 of the refrigerator is opened.

[0148] S340: If the door of the refrigerator is opened, the atomizing fan and the electrolytic water component of the humidifying device are controlled to operate for a second time period.

[0149] If the door 200 of the refrigerator is opened, the controller 500 may generate a third control signal and a fourth control signal, and send the third control signal to the atomizing fan 331 and the fourth control signal to the electrolytic water assembly 340. The third control signal is used to instruct the atomizing fan 331 to operate for a second duration, and the fourth control signal is used to instruct the electrolytic water assembly 340 to operate for a second duration to generate electrolytic water, thereby humidifying and sterilizing the refrigeration chamber at the same time.

[0150] S350: If the door of the refrigerator is not opened, control the atomizing fan of the humidifying device to operate for a third time period.

[0151] If the door 200 of the refrigerator is not opened, the controller 500 may generate a third control signal and send the third control signal to the atomizing fan 331 to instruct the atomizing fan 331 to operate for a third time period.
