Description

Technical Field

[0001] The present invention relates to the technical field of humidification products, and in particular to a storage cabinet and a humidification control method of the storage cabinet. Background Art

[0002] As people's living standards improve, different items will be stored in different lockers, and the storage conditions of the lockers will be controlled to meet the storage needs of the items, such as wine cabinets, medicine cabinets, refrigerators, etc. Different items have different requirements for their own storage temperature and humidity. For items with higher storage humidity requirements, the humidity inside the locker cannot be too low, otherwise it may affect the quality of the stored items.

[0003] Existing lockers usually have a humidification module installed inside the cabinet to ensure the humidity requirements inside the cabinet. A small water storage box is installed in the humidification module. The humidified air is distributed inside the cabinet through natural evaporation of the small water storage box or by means of fan-assisted blowing to achieve a suitable humidity environment. The water in the small water storage box will be consumed in the process of humidifying the locker, so it is necessary to replenish water in time when there is a shortage of water. In the prior art, there is already a solution of automatic water injection, which replenishes water for the small water storage box by setting a large water storage box and a solenoid valve. The solenoid valve opens when the power is turned on, so that the water in the large water storage box flows to the small water storage box, reducing the number of manual water injections by the user. In order to realize the automatic water injection function, a liquid level sensor needs to be installed at the bottom and the opening of the small water storage box to monitor the water volume of the small water storage box, control the large water storage box to automatically inject water when the small water storage box is short of water, and stop injecting water in time when the small water storage box is full of water. In addition, it is necessary to set a liquid level sensor at the bottom of the large water storage box to monitor whether the large water storage box is short of water, or by recording the number of times the solenoid valve is energized. When the number of times the solenoid valve is energized exceeds a first preset number of times and the water level state of the small water storage box determined after each solenoid valve is energized is a water shortage state, it is confirmed that the large water storage box is short of water to remind the user to add water to avoid untimely replenishment of the small water storage box.

[0004] However, the inventors found that the prior art has the following problems: the method of setting multiple liquid level sensors in the prior art greatly increases the manufacturing cost of the humidification module and reduces the user's purchasing experience. In addition, by judging that the small water storage box is short of water and then controlling the large water storage box to replenish water, when the large water storage box is also short of water and cannot be replenished in time, the humidification device will not work for a period of time, affecting the normal operation of the locker.

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1 , is a first structural schematic diagram of a locker provided by an embodiment of the present invention. The embodiment of the present invention provides a locker 10, including a cabinet 11, wherein a storage compartment 12 is formed in the cabinet, and the storage compartment 12 is used to store items. The storage compartment 12 can be configured as a plurality of storage layers, a plurality of storage compartments, etc., or other formats according to user needs, which does not affect the beneficial effects of the present invention.

[0060] It should be noted that the storage cabinet 10 can be used in a variety of scenarios to store different types of items, such as a wine cabinet, a medicine cabinet, a merchandise cabinet or a refrigerator, thereby providing a storage environment with corresponding conditions for different types of items.

[0061] Typically, in order to ensure a suitable ambient temperature and humidity inside the storage compartment 12 , the locker 10 is further provided with a refrigeration device 13 and a humidification device 14 connected to the storage compartment 12 .

[0062] The refrigeration device 13 is used to provide cold capacity for the storage room 12 to reduce the compartment temperature of the storage room 12 and keep the storage room 12 at a low temperature. The refrigeration device 13 can be a compressor refrigeration, a semiconductor refrigeration or other refrigeration methods. The output cold capacity of the refrigeration device 13 can be adjusted according to actual needs. The adjustment of the output cold capacity is adjusted according to the system demand load, and is determined by comprehensively adjusting the ambient temperature, the compartment temperature and the humidity of the compartment, so as to control the temperature and humidity of the storage room to meet the requirements. Among them, when the compressor refrigeration method is adopted, the purpose of adjusting the output cold capacity can be achieved by adjusting the operating speed and / or operating frequency of the compressor. When semiconductor refrigeration is adopted, the purpose of adjusting the output cold capacity can be achieved by adjusting the input voltage. Of course, if other refrigeration methods are adopted, the output cold capacity can also be adjusted according to actual conditions, which will not be repeated here.

[0063] As an optional implementation, the refrigeration device 13 adopts a compressor refrigeration method, and the refrigeration device 13 includes components such as a compressor, a condenser, a drying filter, a capillary tube and an evaporator. The working structure of the refrigeration device 13 includes a compression process, a condensation process, a throttling process and an evaporation process. Among them, the compression process is: when the locker is powered on, when there is a refrigeration demand in the storage room, the compressor starts to work, and the low-temperature and low-pressure refrigerant is sucked into the compressor, and is compressed into a high-temperature and high-pressure superheated gas in the compressor cylinder and then discharged into the condenser; the condensation process is: the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, the temperature continues to drop, and is gradually cooled to a saturated vapor at room temperature and high pressure, and further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this time is called the condensation temperature. The pressure of the refrigerant remains almost unchanged during the entire condensation process; the throttling process is: the condensed refrigerant saturated liquid is filtered out of water and impurities by the drying filter and flows into the capillary tube, through which it is throttled and depressurized, and the refrigerant becomes wet steam at room temperature and low pressure; the evaporation process is: it then begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, repeating the above process, transferring the heat in the storage room to the air outside the cabinet, achieving the purpose of refrigeration.

[0064] Of course, the specific form of the refrigeration device and its refrigeration method involved in the above scenario are only examples. In actual applications, they can be set according to actual conditions and are not specifically limited here.

[0065] See also Figure 2 , is a schematic diagram of the first structure of the humidifying device in the embodiment of the present invention. The humidifying device 14 is used to provide moisture for the storage compartment 12, and plays a role in adjusting the compartment humidity of the storage compartment. It can start or stop running according to control requirements. Specifically, the humidifying device 14 includes a first water storage box 141, a second water storage box 142 and a liquid level sensor 143; wherein, the first water storage box 141 is arranged in the cabinet 11, and is used to provide humidified water for the storage compartment 12. The second water storage box 142 is arranged in the cabinet 11, for example, it can be arranged at the bottom of the cabinet, and is connected to the first water storage box 141, and is used to replenish water for the first water storage box 141. Usually, the capacity of the second water storage box 142 is greater than that of the first water storage box 141.

[0066] In some embodiments, Figure 2As shown, at least a first storage compartment and a second storage compartment are formed in the cabinet 11, and the first storage compartment and the second storage compartment are separated by a first compartment partition, and the humidifying device 14 also includes a first humidifying fan and a second humidifying fan. The first water storage box 141 is built into the first compartment partition; the first water storage box is provided with a first air outlet toward the first storage compartment and a second air outlet toward the second storage compartment, respectively, and the first humidifying fan supplies air to the first water storage box when it is started, and guides the humidified air in the first water storage box to the first storage compartment through the first air outlet; the second humidifying fan supplies air to the first water storage box when it is started, and guides the humidified air in the first water storage box to the second storage compartment through the second air outlet.

[0067] Preferably, the first water storage box comprises a water storage box body and a water storage box cover, and the water storage box cover is detachably covered on the opening of the water storage box body. An isolation component is provided on a surface of the water storage box cover close to the water storage box body, and the vertical height of the isolation component is less than the depth of the water storage box body; the isolation component and the water in the water storage box body form an air isolation layer to divide the water storage box body into a first water storage part and a second water storage part that are connected;

[0068] The first water storage part is provided with a first air inlet and a first air outlet facing the first storage compartment, and the air outlet of the first humidifying fan is connected to the first air inlet; when the first humidifying fan is started and operated, air is supplied to the first water storage box 141, and the humidified air in the first water storage box 141 is guided to the first storage compartment through the first air outlet; the second water storage part is provided with a second air inlet and a second air outlet facing the second storage compartment, and the air outlet of the second humidifying fan is connected to the second air inlet; when the second humidifying fan is started and operated, air is supplied to the first water storage box 141, and the humidified air in the first water storage box 141 is guided to the second storage compartment through the second air outlet.

[0069] By adopting the technical means of this embodiment, the first water storage box of the humidifying device is arranged in the compartment partition of the adjacent first storage compartment and the second storage compartment, and air is supplied to the first water storage box through two humidifying fans, so that the high-humidity air in the first water storage box enters the corresponding compartment from the first air outlet and the second air outlet respectively, and then the humidity of the corresponding compartment is adjusted. That is, the humidity of multiple storage compartments can be adjusted through one water storage box for humidification, thereby reducing the manufacturing cost of the humidification module and improving the user experience.

[0070] In addition, an insulating component is provided on the cover of the first water storage box, and there is a certain gap between the insulating component and the bottom of the body of the first water storage box, so that the water stored in the first water storage box can circulate. At the same time, the insulating component and the water form an air insulating layer, so that only water circulates but air does not circulate between the first water storage part and the second water storage part divided by the first water storage box, thereby preventing air convection between the first storage compartment and the second storage compartment, and avoiding the situation where the temperature and humidity of the first storage compartment and the second storage compartment are set at different levels, and the temperature and humidity interfere with each other due to air exchange.

[0071] Furthermore, a third storage compartment is provided in the cabinet, the third storage compartment is separated from the second storage compartment by a second compartment partition, and the third storage compartment is close to the bottom of the cabinet; the second water storage box 142 is located below the third storage compartment, the second water storage box is provided with a third air outlet facing the third storage compartment, and the humidified air in the second water storage box is guided to the third storage compartment through the third air outlet.

[0072] By adopting the technical means of this embodiment, the second water storage box 142 is used to replenish water for the first water storage box 141, and is also reused to provide moisture for the third storage compartment, and the humidity in the third storage compartment is adjusted by replenishing humidity to the third storage compartment through the third air outlet through natural evaporation of a large area of ​​liquid surface. By reusing the second water storage box, there is no need to set up an additional small water storage box with the same function as the first water storage box in the third storage compartment for humidification, which further simplifies the structure of the humidification device and reduces the manufacturing cost of the humidification device.

[0073] Furthermore, the liquid level sensor 143 is disposed at the liquid level height of the target water storage volume N1 of the first water storage box 141, and is used to send a full water signal when the water storage volume of the first water storage box 141 reaches the target water storage volume N1.

[0074] It should be noted that the target water storage capacity N1 may be the maximum water storage capacity of the first water storage box 141 , or may be any water storage capacity less than the maximum water storage capacity set according to user needs.

[0075] The liquid level sensor 143 can be a sensor constructed based on the principle of liquid level pressure detection. When the water level in the first water storage box 141 rises to the position of the liquid level sensor 143, the liquid level sensor 143 detects the change in liquid pressure and sends out the full water signal; of course, the liquid level sensor 143 can also be a sensor constructed based on the principle of obstacle obstruction. When the water level in the first water storage box 141 rises to the position of the liquid level sensor 143, the liquid level sensor 143 detects obstruction and sends out the full water signal; of course, the liquid level sensor 143 can also be set based on other detection principles, as long as it can realize the function of sending a full water signal when the water storage capacity of the first water storage box 141 reaches the target water storage capacity N1, it will not affect the beneficial effects achieved by the present invention.

[0076] Optionally, in the humidifying device 14, the humidified air can be distributed in the cabinet by natural evaporation of the first water storage box or by fan-assisted blowing, or a plurality of humidifying jet holes can be provided on the inner wall of the storage compartment 12. When the humidifying device 14 is started, the water in the first water storage box is sprayed out from the jet holes to form a fine spray-like mist to achieve the humidification effect. Of course, other humidification methods can also be used or combined without affecting the beneficial effects achieved by the present invention.

[0077] Furthermore, the locker 10 also includes a controller 15, which is connected to the refrigeration device 13 and the humidification device 14 respectively to realize information collection, calculation and analysis, and issuance of control instructions, thereby controlling the operating parameters of the refrigeration device 13, the start-up or shutdown of the humidification device 14 and other working states.

[0078] Specifically, see Figure 3 , is a schematic diagram of the first working process of the controller in an embodiment of the present invention. The controller 15 is specifically used to execute steps S11 to S13:

[0079] S11, after the locker is powered on, controlling the second water storage box to perform a water filling action to replenish water for the first water storage box;

[0080] S12, if the full water signal is received within a first time period after the water filling action starts, control the second water storage box to stop the water filling action; after the water filling stops and a second time period has passed, control the second water storage box to perform the water filling action again;

[0081] S13: If the full water signal is not received within a first period of time after the water filling action starts, it is determined that the second water storage box is short of water.

[0082] In the embodiment of the present invention, after the locker 10 is powered on, the humidifier 14 also starts to operate in response to the corresponding control command. When the humidifier 14 starts to operate for the first time, water is first added to the second water storage box 142. The water injection method can be manual water injection by the user or water injection through an external water source. The amount of water injected into the second water storage box 142 generally does not exceed three quarters of the maximum capacity of the second water storage box 142. Then, after the second water storage box 142 is injected with water, the second water storage box 142 is controlled to perform the water injection action to replenish water for the first water storage box 141. The liquid level sensor 143 detects in real time whether the water storage in the first water storage box 141 has reached the liquid level height of the corresponding target water storage volume N1.

[0083] In the embodiment of the present invention, a first time duration t1 is set to characterize the maximum filling time of the first water storage box 141, and the maximum filling time is calculated based on the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the preset water filling speed. Since the process of filling water into the first water storage box 141 is achieved by extracting static water from the second water storage box, the water flow rate is stable, and the water filling flow rate is usually stable, and the first time duration t1 can be calculated based on the preset water filling speed. After the second water storage box 142 performs the water filling action of replenishing water to the first water storage box 141, the timing module built into the controller 15 starts timing. If a full water signal sent by the liquid level sensor 143 is received within the first time duration t1, it indicates that the water filling process is normal and the water storage capacity in the second water storage box 142 is also sufficient. After receiving the full water signal, the second water storage box 142 is controlled to stop the water filling action. Thereafter, the humidification device 14 works normally, consuming the water in the first water storage box 141 to provide humidity for the storage compartment 12.

[0084] Preferably, the first duration is calculated according to the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the preset water filling speed by the following calculation formula:

[0085]

[0086] Wherein, t1 is the first time length, N1 is the target water storage capacity of the first water storage box, N min is the preset minimum water storage capacity, u is the preset water injection speed, k is the preset safety factor, 0<k<(N max –N1) / u,N max The preset maximum water storage capacity.

[0087] The embodiment of the present invention sets a second time length t2 to characterize the fastest water consumption time of the first water storage box 141, that is, the time required to consume the water in the first water storage box 141 assuming that the humidification device is in continuous operation. The second time length is calculated based on the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the water consumption rate. The water consumption rate can be calculated and tested based on prior knowledge. The preset minimum water storage capacity refers to the minimum water storage capacity required to be retained in the first water storage box 141. After the water injection action of the second water storage box 142 is completed, that is, after the water injection into the first water storage box 141 is stopped, the timing module starts timing, and after the second time length t2 has passed, the second water storage box 142 is controlled again to perform the water injection action to replenish water for the first water storage box 141, and this cycle is repeated.

[0088] As the number of times water is replenished to the first water storage box 141 increases, the water in the second water storage box is consumed. If the second water storage box 142 performs a water filling action and no full water signal is received from the liquid level sensor 143 within the first time duration t1, it indicates that the water in the second water storage box 142 is consumed, and it is determined that the second water storage box 142 is short of water.

[0089] Preferably, the second duration is calculated according to the target water storage capacity of the first water storage box, the preset minimum water storage capacity and the water consumption rate by the following calculation formula:

[0090]

[0091] Wherein, t2 is the second time length, N1 is the target water storage capacity of the first water storage box, N min is the preset minimum water storage capacity, and v is the water consumption rate.

[0092] By adopting the technical means of the embodiment of the present invention, the first water storage box is arranged in the storage room for humidity adjustment, and the second water storage box is arranged to replenish water for the first water storage box. By arranging a liquid level sensor on the first water storage box to monitor the water filling process of the first water storage box and the second water storage box at the same time, the water filling process of the first water storage box is terminated in time when the first water storage box is full of water, so as to prevent the small water storage box from being short of water and overflowing, and it is possible to monitor whether the second water storage box is short of water, so as to add water to the second water storage box in time. Compared with the prior art of monitoring the water shortage state and the full water state in the large water storage box and the small water storage box by arranging multiple liquid level sensors, the embodiment of the present invention can reduce the manufacturing cost of the humidification device, and the present invention determines that the second water storage box is short of water by judging that the first water storage box is not full of water within a certain period of time. At this time, there is usually residual water in the first water storage box, which can ensure that the humidification device continues to work normally in a short time, thereby improving the user experience.

[0093] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiments. Figure 4 , is a second structural diagram of a humidifying device in an embodiment of the present invention, wherein the humidifying device 14 further comprises a water injection pipe 144 and a water injection pump 145, and the second water storage box 142 is connected to the first water storage box 141 via the water injection pipe 144 and the water injection pump 145. Figure 4 As shown, one end of the water injection pipe 144 is inserted into the water injection port of the first water storage box 141, and the other end is inserted into the water outlet of the second water storage box 142, and the water injection pump 145 is arranged on the water injection pipe 144. Under the control of the controller 15, the water injection pump 145 is turned on at regular intervals to extract water from the second water storage box 142 and inject it into the first water storage box 141.

[0094] Then in steps S11 and S12, the controlling the second water storage box to perform the water filling action is specifically: controlling the water filling pump to start, so as to pump water from the second water storage box to the first water storage box through the water filling pipe.

[0095] As a preferred implementation, the embodiment of the present invention is further implemented on the basis of any of the above embodiments, and the embodiment of the present invention optimizes the way of injecting water when the second water storage box is short of water.

[0096] In the first alternative embodiment, see Figure 5 , is a third structural schematic diagram of a humidifying device in an embodiment of the present invention, wherein the humidifying device 14 further comprises an external water pipe 146 and a water valve 147, and the second water storage box 142 is connected to an external water source via the external water pipe 146 and the water valve 147. Figure 5 As shown, one end of the external water pipe 146 is inserted into the water injection port of the second water storage box 142, and the other end is connected to an external water source, such as a reservoir, a pool, etc. A water valve 147 is provided on the external water pipe 146, and the water valve 147 is used to control the start and stop of the water injection process of the second water storage box 142. The water valve 147 is started or stopped under the control of the controller 15, and the water in the external water source is extracted and injected into the second water storage box 142 when it is started.

[0097] See Figure 6 , is a schematic diagram of a second working process of the controller in an embodiment of the present invention. In step S13, that is, after determining that the second water storage box is short of water, the controller is further configured to execute step S14:

[0098] S14, controlling the water valve to open so as to pump water from the external water source to the second water storage box through the external water pipe.

[0099] Preferably, the humidifying device further comprises a flow meter, which is arranged on the external water pipe and is used to monitor the real-time water injection flow of the external water pipe.

[0100] Then in step S14, that is, after controlling the water valve to open so as to pump water from the external water source to the second water storage box through the external water pipe, the controller is further configured to execute steps S15 and S16:

[0101] S15, judging whether the current water storage capacity of the second water storage box reaches the target water storage capacity corresponding to the second water storage box according to the real-time water injection flow rate and the accumulated opening time of the water valve;

[0102] S16: If yes, control the water valve to close to stop pumping water to the second water storage box.

[0103] In the embodiment of the present invention, water is replenished for the second water storage box by using an external water source. The target water storage capacity N2 corresponding to the second water storage box may be the maximum water storage capacity of the second water storage box 142, or any water storage capacity less than the maximum water storage capacity set according to user needs. Since the external water source may be affected by regional water pressure differences and the water flow rate is unstable, a flow meter is set to monitor the water injection flow in real time, and the capacity of the water currently injected into the second water storage box 142 is calculated based on the real-time water injection flow and the accumulated opening time of the water valve, and then the water injection is stopped when the current water storage capacity reaches the target water storage capacity N2.

[0104] In the embodiment of the present invention, the water injection pump 145 is used to pump water from the second water storage box 142 into the first water storage box 141. Therefore, the preset water injection speed u, that is, the pumping speed of the water injection pump 145, can be obtained by pre-testing. The maximum working time of the water injection pump each time, that is, the first time length, is Among them, the setting of k value is used to eliminate the individual error of the water pump.

[0105] The embodiment of the present invention ensures that the liquid level sensor 143 will definitely detect the full water signal during the maximum working time of the water filling pump. Whenever the liquid level sensor detects the full water signal, the water filling pump is immediately stopped to terminate the water filling process of the small water box.

[0106] The embodiment of the present invention maintains the water storage amount N in the first water storage box at N1>N>N by designing the setting position of the liquid level sensor, the maximum working time of the water injection pump (the first time length t1) and the water injection time interval (the second time length t2). minThis ensures that the first water storage box will not overflow with water, and that air will not circulate in the first water storage box, causing the room temperature and humidity to interfere with each other and the first water storage box to be short of water. At the same time, because the water injection pump will start to extract water from the second water storage box to replenish the first water storage box at intervals of t2, when the water volume of the second water storage box is sufficient, the liquid level sensor will definitely detect a full water signal within the maximum working time t1 of the water injection pump. Therefore, when the liquid level sensor still does not detect a full water signal after the water pump starts working for a certain period of time, it can be determined that the second water storage box is short of water at this time, and the water valve is controlled to open to inject water into the second water storage box, realizing that one liquid level sensor monitors and simultaneously detects the water level status of the large and small water boxes.

[0107] As a preferred embodiment, see Figure 7 , is a second structural diagram of a locker provided in an embodiment of the present invention, wherein the locker further comprises an alarm device 16, and the alarm device 16 is used to execute a preset fault alarm action.

[0108] See Figure 8 , is a third working flow diagram of the controller in an embodiment of the present invention. In step S16, that is, after controlling the water valve to close to stop pumping water to the second water storage box, the controller is further configured to execute step S17:

[0109] S17: If the full water signal is still not received after the third period of time has passed, control the alarm device to execute a preset fault alarm action.

[0110] After the second water storage box 142 is replenished with water, the second water storage box 142 will continue to perform the water filling action for the first water storage box 141, and stop the water filling action when receiving the full water signal from the liquid level sensor 143. In the embodiment of the present invention, if the second water storage box is filled with water, that is, after pumping water to the second water storage box is stopped, after the third time t3, the full water signal sent by the liquid level sensor 143 is still not received, indicating that the water filling process has a fault, then the control alarm device 16 executes a preset fault alarm action to remind the user to check and repair.

[0111] Optionally, the alarm device 16 can be set in the form of a display screen to realize fault alarm by displaying preset text information; the alarm device 16 can also be set in the form of a voice module to realize fault alarm by playing preset voice content; the alarm device 16 can also be set in the form of an LED light group to realize fault alarm according to a set display frequency or display color, etc.; the alarm device 16 can also be set in the form of a buzzer to realize fault alarm by emitting a whistle sound with a set frequency or a set volume. Of course, the alarm device 16 can also be any two of the above forms or a combination of two forms, or other fault alarm forms, all of which do not affect the beneficial effects achieved by the present invention.

[0112] In the second alternative embodiment, see Fig. 9 , is a third structural diagram of a locker provided in an embodiment of the present invention, wherein the locker further comprises a reminder device 17, and the reminder device 17 is used to execute a preset reminder action.

[0113] See Fig.10 , is a fourth working flow diagram of the controller in an embodiment of the present invention. In step S13, that is, after determining that the second water storage box is short of water, the controller is further configured to execute step S14':

[0114] S14', controlling the reminder device to execute a preset reminder action; wherein the reminder action is used to remind the user to refill the second water storage box with water.

[0115] In the embodiment of the present invention, the user manually adds water to replenish the second water storage box. When it is determined that the second water storage box 142 is short of water, the controller 15 controls the reminder device 17 to start running and execute the corresponding reminder action. After receiving the reminder content, the user manually adds water to the second water storage box through the water filling port 1421 on the second water storage box.

[0116] Optionally, the reminder device 17 can be set in the form of a display screen, and the water replenishment reminder is realized by displaying preset text information; the reminder device 17 can also be set in the form of a voice module, and the water replenishment reminder is realized by playing preset voice content; the reminder device 17 can also be set in the form of an LED light group, and the water replenishment reminder is realized according to a set display frequency or display color, etc.; the reminder device 17 can also be set in the form of a buzzer, and the water replenishment reminder is realized by emitting a whistle sound with a set frequency or a set volume. Of course, the reminder device 17 can also be any two of the above forms or a combination of two forms, or it can be other reminder forms, all of which do not affect the beneficial effects achieved by the present invention.

[0117] Preferably, the locker further includes an alarm device 16; after controlling the reminder device to perform a preset reminder action, the controller is further configured to perform step S15':

[0118] S15', if the full water signal is still not received after the fourth time period has passed, control the alarm device to execute a preset fault alarm action.

[0119] After issuing a reminder action to remind the user to refill water, if the user refills the second water storage box 142 in time, the second water storage box 142 will continue to perform the water filling action for the first water storage box 141, and stop the water filling action when receiving the full water signal from the liquid level sensor 143. In the embodiment of the present invention, if the reminder device 17 performs the reminder action and after the fourth time period t4 has passed, it still has not received the full water signal sent by the liquid level sensor 143, indicating that the user has not refilled water, or the water filling process has a fault, then the alarm device 16 is controlled to perform a preset fault alarm action to remind the user to check and repair.

[0120] It should be noted that the humidifying device 14 can also replenish water for the second water storage box in two ways: an external water source and manual water addition by the user, which does not affect the beneficial effects achieved by the present invention.
