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 and a humidity sensor installed inside the locker to humidify the locker. When the humidity sensor detects that the humidity inside the locker is low, the humidification module is controlled to start running. The humidification module is equipped with a small water storage box, which distributes the humid air inside the locker 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 during the humidification process in the locker, so it is necessary to replenish water in time when there is a shortage of water.

[0004] There is already a solution of automatic water filling in the prior art, which is to provide a large water storage box to replenish water for the small water storage box. However, the inventor found that the prior art has the following problems: in order to realize the automatic water filling function, it is necessary to provide a liquid level sensor 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 fill water when the small water storage box is short of water, and stop filling water in time when the small water storage box is full of water. The use of multiple liquid level sensors greatly increases the manufacturing cost of the humidification module and reduces the user's purchasing experience. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a locker and a humidification control method for the locker. By reusing the humidity sensor, the water level of the small water storage box can be monitored to prevent the small water storage box from being short of water and overflowing, thereby ensuring the normal operation of the humidification device and reducing the manufacturing cost of the humidification device.

[0065] 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.

[0066] In the description of the specification and claims, it is to be understood that the terms first, second, etc. in the specification and claims are only used for the purpose of describing the same technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, nor necessarily describing the order or time sequence. The terms are interchangeable where appropriate. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0067] 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.

[0068] 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.

[0069] 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 .

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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 humidifying fan 143; wherein, the first water storage box 141 is arranged in the cabinet 11, and is used to provide humidified moisture 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.

[0074] The first water storage box 141 is provided with an air inlet 1411 and an air outlet 1412 facing the storage compartment 12. The air outlet of the humidifying fan 143 is connected to the air inlet 1411 of the first water storage box 141. When the humidifying fan 143 is started, it supplies air to the first water storage box 141 through the air inlet 1411, blows the air of the cabinet 11 into the first water storage box 141 from the air inlet 1411, and introduces the humidified air in the first water storage box 141 into the storage compartment 12 through the air outlet 1412, thereby providing humidified air for the storage compartment 12.

[0075] The locker 10 further includes a humidity sensor 15 , which is disposed at the air outlet 1412 of the first water storage box 141 and is used to detect the compartment humidity D of the storage compartment 12 .

[0076] Furthermore, the locker 10 also includes a controller 16, which is respectively connected to the refrigeration device 13, the humidification device 14 and the humidity sensor 15 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.

[0077] Specifically, see Figure 3 , is a schematic diagram of a first working process of the controller in an embodiment of the present invention. The controller 16 is specifically used to execute steps S11 to S13:

[0078] S11, after the locker is powered on, controlling the second water storage box to perform a water injection action, and after the execution time of the water injection action reaches a first time length, controlling the second water storage box to stop the water injection action;

[0079] S12, when the compartment humidity detected by the humidity sensor is less than a first humidity threshold, controlling the humidification fan to start running, and after the running time of the humidification fan reaches a second time length, controlling the humidification fan to stop running;

[0080] S13: During the startup of the humidifying fan, when the compartment humidity detected by the humidity sensor is less than a second humidity threshold, the second water storage box is controlled again to perform water injection.

[0081] 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.

[0082] It should be noted that the target water storage capacity N1 of the first water storage box 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.

[0083] Since the process of injecting 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, so the injection speed is usually stable and can be calculated or tested by prior knowledge. Therefore, according to the preset injection speed u, the target water storage capacity N1 of the first water storage box and the preset minimum water storage capacity N min The time required for the water in the first water storage box 141 to reach the required target water storage volume N1, that is, the first time duration t1, is calculated.

[0084] Specifically, it is calculated by the following 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] It should be noted that the maximum water storage capacity N maxis the maximum amount of water that the first water storage box 141 can store, and the minimum amount of water N min ≥ 0. k is the preset safety factor value, which is used to eliminate the individual error of the water injection pump.

[0088] In the process of controlling the second water storage box 142 to inject water into the first water storage box 141 , the timing module built into the controller 16 performs timing, and when the water injection time reaches the first time t1 , the second water storage box is controlled to stop the water injection action.

[0089] At the same time, the controller 16 also obtains the compartment humidity D detected by the humidity sensor 15 in real time, and controls the start or stop of the humidification fan 143 according to the compartment humidity D. Specifically, a first humidity threshold D1 is pre-set to characterize the lower compartment humidity of the storage compartment 12. When the humidification fan 143 is not started, if the controller 16 determines that the current compartment temperature collected by the humidity sensor 15 satisfies D<D1, and determines that the current compartment humidity of the storage compartment is low and needs to be humidified and replenished with water, the humidification fan 143 is controlled to start running, and air is supplied to the inside of the first water storage box 141 through the air inlet 1411 of the first water storage box 141, so that the air in the cabinet is blown into the first water storage box from the air inlet, and the humidified air in the first water storage box is introduced into the storage compartment 12 through the air outlet 1412, thereby reducing the humidity of the storage compartment 12.

[0090] Because the humidity sensor 15 is arranged at the air outlet of the first water storage box 141, when the humidifying fan starts working, the humidity sensor 15 detects the high humidity air blown out of the first water storage box, which cannot correctly reflect the actual humidity in the storage compartment 12, that is, it cannot determine whether the actual humidity in the storage compartment 12 reaches the set target humidity threshold Ds, so it is impossible to control the humidifying fan 143 to stop working through the humidity value detected by the humidity sensor 15. In the embodiment of the present invention, the working time of the humidifying module is controlled by program setting, that is, the second time length t2 is pre-set, and when the time length of the humidifying fan 143 starting to run reaches the second time length t2, it is considered that the compartment humidity D in the current storage compartment 12 has reached the set target humidity threshold Ds, and the humidifying fan 143 is controlled to stop running.

[0091] During the startup of the humidification fan 143, the water in the first water storage box 141 will be continuously consumed, and humidified air will be blown out from the air outlet of the first water storage box 141 to provide humidity for the storage compartment 12. Therefore, if there is sufficient water in the first water storage box 141, the compartment temperature D collected by the humidity sensor 15 should be close to or maintained at the target humidity threshold Ds. Based on this, the second humidity threshold D2 is pre-set to satisfy D1≤D2<Ds. During the startup of the humidification fan 143, when the compartment temperature D collected by the humidity sensor 15 is less than D2, it indicates that the water in the first water storage box 141 has been consumed and the first water storage box 141 is in a water shortage state. Therefore, the second water storage box 142 is re-controlled to perform the water injection action to replenish water for the first water storage box 141, so as to circulate.

[0092] Optionally, the second humidity threshold D2 = (Ds-D1) / 2. Of course, the second humidity threshold D2 can also be set to other values ​​satisfying D1≤D2<Ds according to actual conditions, which is not specifically limited here.

[0093] By adopting the technical means of the embodiment of the present invention, the locker is provided with a humidifying device, wherein the humidifying fan supplies air to the inside of the first water storage box when it is started, so that the humidified air in the first water storage box is introduced into the storage compartment through the air outlet to achieve humidity adjustment in the storage compartment, and the second water storage box is used to replenish water for the first water storage box. In addition, a humidity sensor is provided at the air outlet of the first water storage box to detect the humidity of the compartment, and the humidifying fan is controlled to start running when it is detected that the humidity of the compartment is low. During the process of starting the humidifying fan, when the humidity of the compartment detected by the humidity sensor cannot reach the high humidity value, it is determined that the first water storage box is short of water, and the second water storage box is controlled to perform water injection, and the water injection is stopped when the water injection action reaches a certain duration. The embodiment of the present invention monitors the humidity of the compartment through a humidity sensor, and also monitors the water volume of the first water storage box, thereby realizing automatic water filling operation of the first water storage box, and preventing the small water storage box from being short of water and overflowing. Compared with the prior art in which multiple liquid level sensors are set to monitor the water shortage state and the water full state in the water storage box, the embodiment of the present invention can ensure the normal operation of the humidifier, effectively reduce the manufacturing cost of the humidifier, and improve the user experience.

[0094] As a preferred embodiment, the second duration t2 is calculated according to the humidification speed of the humidification fan, the preset target humidity threshold and the first humidity threshold by the following calculation formula:

[0095]

[0096] Among them, t2 is the second time length, Ds is the target humidity threshold, D1 is the first humidity threshold, v is the humidification speed of the humidification fan; Ds>D1.

[0097] In the embodiment of the present invention, the time t2 required for the humidifying fan 143 to start running can be calculated based on the difference between the preset target humidity threshold Ds and the preset first humidity threshold D1, combined with the humidifying speed v of the humidifying fan. That is, when the time for the humidifying fan 143 to start running reaches the second time t2, it is considered that the current compartment humidity inside the storage compartment 12 reaches the target humidity threshold Ds, and the humidifying fan 143 is controlled to stop running.

[0098] It should be noted that the humidification speed v of the humidification fan 143 is affected by the compartment temperature T and the compartment humidity D of the storage compartment 12 when the humidification fan is started.

[0099] The locker 10 further includes a temperature sensor, which is disposed in the storage compartment 12 and is used to detect the compartment temperature T. The humidification speed v of the humidification fan 143 is calculated by the following calculation formula based on the compartment humidity D detected by the humidity sensor and the compartment temperature T detected by the temperature sensor when the humidification fan 143 is started:

[0100] v = aD + bT + k;

[0101] Wherein, D is the humidity of the compartment, T is the temperature of the compartment; a and b are respectively the preset humidity coefficient and temperature coefficient, and k is a preset constant value.

[0102] It should be noted that the values ​​of humidity coefficient a, temperature coefficient b and constant k are obtained in advance through experimental tests. Multiple groups of compartment humidity, compartment temperature and humidification speed are collected through multiple tests, and the specific values ​​of a, b and k are determined by function fitting and other methods. No specific limitation is made here.

[0103] By adopting the technical means of the embodiment of the present invention, the humidification speed of the humidification fan is calculated taking into account the compartment temperature and the compartment humidity, which is used to realize the calculation of the required operating time t2 of the humidification fan, and effectively improves the calculation accuracy of the required operating time of the humidification fan, so as to ensure that the compartment humidity of the storage compartment can reach the target humidity threshold when the humidification fan stops running, meeting the user's requirements.

[0104] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiments. Figure 4 , is a schematic diagram of a second working process of the controller in an embodiment of the present invention. After step S14, the controller is further configured to execute steps S14 and S15:

[0105] S14, recording the cumulative number of executions of the water injection action;

[0106] S15. When the cumulative execution times of the water filling action is greater than or equal to a preset times threshold, it is determined that the second water storage box is short of water; wherein the preset times threshold is calculated based on the ratio of the target water storage capacity of the second water storage box and the water filling capacity of a single water filling action.

[0107] It should be noted that the target water storage capacity N2 of the second water storage box can be the maximum water storage capacity of the second water storage box 142, or it can be any water storage capacity less than the maximum water storage capacity set according to user needs, such as three quarters of the maximum water storage capacity of the second water storage box.

[0108] In the embodiment of the present invention, the number of times that the second water storage box 142 can fill the first water storage box 141 with water is calculated based on the target water storage capacity of the second water storage box 142 and the water injection amount of a single water injection action, which is used as the preset number threshold. Specifically, the ratio N2 / △N of the target water storage capacity of the second water storage box and the water injection amount of a single water injection action is calculated, and the preset number threshold m is obtained by rounding up. Wherein, ΔN=N1-N min , that is, the difference between the target water storage capacity and the minimum water storage capacity of the first water storage box 141.

[0109] The embodiment of the present invention accumulates the number of times the second water storage box 142 performs the water injection action. As the number of times water is replenished to the first water storage box 141 increases, the water in the second water storage box 142 is consumed. When the accumulated number of water injection actions n satisfies n≥m, 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.

[0110] By adopting the technical means of the embodiment of the present invention, the water injection action of the second water storage box is accumulated. When the accumulated number of executions of the water injection action reaches a certain threshold number, it is determined that the second water storage box is short of water, so that water can be replenished for the second water storage box in time to ensure the normal operation of the humidification device.

[0111] As a preferred embodiment, see Figures 5 to 7 , Figure 5 is a first structural schematic diagram of a first water storage box in an embodiment of the present invention, Figure 6 is a second structural schematic diagram of the first water storage box in an embodiment of the present invention, Figure 7Schematic diagram of the installation position of the humidity sensor in the embodiment of the present invention. In the embodiment of the present invention, the first water storage box 141 and the humidifying fan 143 are arranged in the compartment partition 121 of the storage compartment 12. The compartment partition 121 includes a partition body 1211 and a partition top cover 1212. The partition top cover 1212 is detachably covered on the partition body 1211. The first water storage box 141 and the humidifying fan 143 are arranged inside the partition body 1211, and the partition top cover 1212 is provided with an air outlet 1213 of the partition top cover at a position corresponding to the air outlet 1412 of the first water storage box 141, and the outlet direction is consistent with the inside of the storage compartment 12. The humidity sensor 15 is arranged at the air outlet 1213 of the partition top cover 1212.

[0112] The first water storage box also includes a humidifying fiber 1413, a moisture-conducting block and a water injection port. The second water storage box 142 injects water into the water storage part of the first water storage box through the water injection port. The moisture-conducting block is arranged in the water storage part, and the humidifying fiber is arranged above the moisture-conducting block. The water in the first water storage box 142 penetrates upward to the humidifying fiber through the moisture-conducting block, so that the humidifying fan 143 guides the humidified air in the humidifying fiber into the storage compartment 12 through the air outlet 1412.

[0113] By adopting the technical means of the embodiment of the present invention, the first water storage box and the humidification fan are arranged in the compartment partition, which does not occupy the space of the storage compartment, thereby improving the space utilization rate of the locker, and the humidification fiber is installed above the moisture-conducting block to absorb water to keep itself moist, which greatly increases the evaporation area of ​​water, thereby being more conducive to regulating the humidity in the storage compartment. In addition, due to the characteristics of the humidification fiber, even if the first water storage box is out of water, the humidification fiber can still maintain a moist state for a period of time to maintain the humidification performance, so to a certain extent, it can offset the control accuracy problem of water injection into the first water storage box caused by the water consumption calculation error.

[0114] As a preferred implementation, the present invention is further implemented on the basis of the above-mentioned embodiments. Figure 7 , 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 8 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 16, the water injection pump 144 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.

[0115] Then, 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.

[0116] It can be understood that the start time of the water injection pump is the first time period t1, and the preset water injection speed is the water pumping speed of the water injection pump 145 .

[0117] 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.

[0118] In the first alternative embodiment, see Fig. 9 , 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 through the external water pipe 146 and the water valve 147. 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. The water valve 147 is arranged 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.

[0124] S18: If yes, control the water valve to close to stop pumping water to the second water storage box.

[0125] In the embodiment of the present invention, water is replenished in the second water storage box by using an external water source. 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 current water volume 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 volume reaches the target water storage volume N2.

[0128] S16', controlling the reminding device to execute a preset reminding action; wherein the reminding action is used to remind the user to refill the second water storage box with water.

[0129] In the embodiment of the present invention, the second water storage box is replenished with water by manually adding water by the user. When it is determined that the second water storage box 142 is short of water, the controller 16 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.

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.

[0131] 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.
