[0039] The above and other aspects, features and advantages of the present application will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

[0040] Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present application, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present application. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as a basis and representative basis for the claims to teach those skilled in the art to use the present application in a variety of ways with substantially any suitable detailed structure.

[0041] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present application.

[0042] The control method of the storage cabinet in the embodiment of the present application obtains the current temperature and current humidity of the storage cabinet, determines the comparison result between the current temperature and the corresponding temperature, and the comparison result between the current humidity and the corresponding humidity, and then controls the evaporating fan, heater and humidifier according to the state of the compressor, so that the temperature and humidity in the storage cabinet can reach the corresponding target temperature and target humidity, thereby realizing precise adjustment of the temperature and humidity of the storage cabinet and improving the reliability of the storage cabinet.

[0043] like Figure 1 As shown, the following steps are included:

[0044] Step S101, obtaining the current temperature of the storage cabinet through the temperature sensor of the storage cabinet.

[0045] In this embodiment, the storage cabinet can provide a constant temperature and humidity storage environment, and its storage objects can include, for example, one or more of food, red wine, medicine, medicinal materials, tea, documents, etc. The storage cabinet is provided with a temperature sensor, a humidity sensor, a compressor, an evaporating fan, an evaporator, a heater, and a humidifier. The storage cabinet is also provided with a condenser, and the compressor, evaporator, and condenser are connected through a refrigerant circulation loop. The refrigerant in the evaporator evaporates and absorbs heat, which can achieve cooling and dehumidification of the surrounding air.

[0046] The evaporating fan can transport the air in the storage space of the storage cabinet to the evaporator and heater of the storage cabinet and return to the storage space. The evaporator can dehumidify and cool the passing air after the compressor is turned on, and the heater can heat the passing air after it is turned on.

[0047] The current temperature of the storage cabinet can be obtained in real time or periodically through a temperature sensor.

[0048] Optionally, the humidifier can be composed of a humidifying fan and a fan channel, which can evaporate the water in the water tank by blowing air downwards, thereby achieving a humidification effect. The humidifier can also be composed of an ultrasonic atomizer, which uses electronic high-frequency oscillation through the high-frequency resonance of the atomizing sheet to break up the liquid water molecular structure and produce a natural and elegant water mist, thereby achieving a humidification effect.

[0049] Optionally, the evaporation fan and the evaporator may be provided separately, or the evaporation fan may be integrated on the evaporator.

[0050] Optionally, the temperature sensor and the humidity sensor may be provided independently, or the two may be integrated into one component.

[0051] Step S102, obtaining the current humidity of the storage cabinet through the humidity sensor of the storage cabinet.

[0052] In this embodiment, the current humidity of the storage cabinet is obtained in real time or periodically through a humidity sensor.

[0053] Step S103, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is greater than the first humidity, determine the state of the compressor of the storage cabinet, wherein the first humidity is greater than the target humidity, and execute step S104 or step S105.

[0054] In this embodiment, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is greater than the first humidity, it means that the current temperature is suitable and the current humidity is high. In this case, the state of the compressor is determined to determine whether to turn on the heater.

[0055] Step S104: if the compressor is in operation, the evaporation fan of the storage cabinet is turned on or the evaporation fan is kept running, the heater of the storage cabinet is turned on, and the humidifier of the storage cabinet is turned off.

[0056] In this embodiment, if the compressor is in operation, the evaporator fan of the storage cabinet is turned on or kept running to start or continue to use the evaporator to dehumidify the storage cabinet. In order to avoid the temperature of the storage cabinet being too low during the dehumidification process, the heater of the storage cabinet is turned on to heat the air, and the humidifier is turned off to avoid further increase in humidity.

[0057] Step S105, if the compressor is in a shutdown state and the shutdown time reaches a first time, start the compressor, start the evaporation fan, start the heater, and turn off the humidifier.

[0058] In this embodiment, in order to avoid frequent startup of the compressor and overheating of the compressor motor, after shutting down the compressor, the compressor can be restarted only after the shutdown time reaches the first time. If the compressor is in a shutdown state and the shutdown time reaches the first time, the compressor can be started and the evaporation fan can be started to start dehumidification. In order to avoid the temperature of the storage cabinet being too low during the dehumidification process, the heater is turned on to heat the air, and the humidifier is turned off to prevent the humidity from further increasing.

[0059] In the specific application scenario of the present application, the first temperature = target temperature + 1, the first humidity = target humidity + 5%, and the first duration is 5 minutes.

[0060] It should be noted that the current temperature and the current humidity are both the current temperature and the current humidity in the storage cabinet. In some embodiments, they are the current temperature and the current humidity of the storage space in the storage cabinet.

[0061] The control method of the storage cabinet of the embodiment of the present application includes: obtaining the current temperature of the storage cabinet through the temperature sensor of the storage cabinet; obtaining the current humidity of the storage cabinet through the humidity sensor of the storage cabinet; if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is greater than the first humidity, determining the state of the compressor of the storage cabinet, wherein the first humidity is greater than the target humidity; if the compressor is in the running state, turning on the evaporation fan of the storage cabinet or keeping the evaporation fan running, turning on the heater of the storage cabinet, and turning off the humidifier of the storage cabinet; if the compressor is in the shutdown state and the shutdown time reaches the first time, turning on the compressor, turning on the evaporation fan, turning on the heater, and turning off the humidifier; wherein the evaporation fan can transport the air in the storage space of the storage cabinet to the evaporator and heater of the storage cabinet, and return to the storage space, the evaporator can dehumidify and cool the passing air after the compressor is turned on, and the heater can heat the passing air after it is turned on. Thus, the temperature and humidity in the storage cabinet reach the corresponding target temperature and target humidity, and the precise adjustment of the temperature and humidity of the storage cabinet is achieved, and the reliability of the storage cabinet is improved.

[0062] In some embodiments of the present application, Figure 2 As shown, the method further comprises the following steps:

[0063] Step S106, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, determine the state of the compressor and the evaporating fan, wherein the second humidity is less than the target humidity.

[0064] In this embodiment, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, it means that the current temperature and the current humidity are appropriate. At this time, the status of the compressor and the evaporating fan is determined to determine whether dehumidification is in progress.

[0065] In the specific application scenario of the present application, the second humidity=target humidity-5%.

[0066] Step S107: if the compressor and the evaporating fan are both in operation, the heater is turned on intermittently according to the target start-stop strategy, and the humidifier is turned off.

[0067] In this embodiment, if the compressor and the evaporation fan are both in operation, it means that the evaporator is being used for dehumidification. In order to prevent the temperature of the storage cabinet from being too low during the dehumidification process, the heater is turned on intermittently according to the target start-stop strategy, and the humidifier is turned off to prevent the humidity from further increasing. Among them, the target start-stop strategy intermittently turning on the heater can prevent the temperature from being too low and reduce the energy consumption of the heater. For example, the target start-stop strategy can be to turn on the heater for 5 seconds and stop for 3 seconds to turn it on intermittently.

[0068] Step S108, if the compressor and the evaporation fan are not both in operation, turn off the compressor, turn off the evaporation fan for a target delay time, turn off the heater, and turn off the humidifier.

[0069] In this embodiment, if the compressor and the evaporation fan are not both in operation, it means that dehumidification is not performed. In this case, the compressor can be turned off, and the evaporation fan can be turned off for a period of time according to the target delay time, so that the air can continue to circulate in the storage cabinet for a period of time through the fan to improve the uniformity of temperature and humidity. The heater and humidifier are turned off to maintain the current temperature and humidity. The target delay time can be, for example, 1.5 minutes.

[0070] When the temperature and humidity of the storage cabinet are appropriate, the compressor, evaporating fan, heater and humidifier are controlled in a corresponding manner according to the status of the compressor and the evaporating fan, thereby ensuring the stability of the temperature and humidity of the storage cabinet.

[0071] In some embodiments of the present application, Figure 3 As shown, the method further comprises the following steps:

[0072] Step S109: if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is not less than the third humidity and less than the second humidity, determine the states of the compressor and the evaporating fan.

[0073] In this embodiment, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is not less than the third humidity and less than the second humidity, it means that the current temperature is appropriate, and the current humidity is low but no humidification is required. At this time, the status of the compressor and the evaporating fan is determined to determine whether dehumidification is in progress.

[0074] In the specific application scenario of the present application, the third humidity=target humidity-10%.

[0075] Step S110, if the compressor and the evaporation fan are both in operation, turn off the compressor, turn off the evaporation fan for a delay time according to the target delay time, turn off the heater, and turn off the humidifier.

[0076] In this embodiment, if the compressor and the evaporator fan are both in operation, it means that the evaporator is being used for dehumidification. In order to prevent the temperature and humidity from further decreasing, the compressor is turned off, the evaporator fan is turned off according to the target delay time, and the heater and humidifier are turned off to maintain the current temperature and humidity.

[0077] Step S111: if the compressor is in an off state and the evaporation fan is in a delayed off state, the evaporation fan is turned off when the target delay time is reached, the heater is turned off, and the humidifier is turned off.

[0078] In this embodiment, if the compressor is in the off state and the evaporating fan is in the delayed off state, it is necessary to turn off the evaporating fan when the target delay time is reached so that the air can continue to circulate in the storage cabinet for a period of time through the fan to improve the uniformity of temperature and humidity. Then, the heater and humidifier are turned off to maintain the current temperature and current humidity.

[0079] Step S112: if the compressor is in the off state and the evaporation fan is not in the delayed off state, turn off the evaporation fan, turn off the heater, and turn off the humidifier.

[0080] In this embodiment, if the compressor is in the off state and the evaporating fan is not in the delayed off state, it means that the evaporating fan has completed the delayed off state, and the evaporating fan, the heater and the humidifier are turned off to maintain the current temperature and the current humidity.

[0081] When the temperature of the storage cabinet is appropriate and the humidity is low, the compressor, evaporating fan, heater and humidifier are controlled in a corresponding manner according to the status of the compressor and the evaporating fan, thereby ensuring the stability of the temperature and humidity of the storage cabinet.

[0082] In some embodiments of the present application, Figure 4 As shown, the method further comprises the following steps:

[0083] Step S113: if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is less than the third humidity, determining the states of the compressor and the evaporation fan.

[0084] In this embodiment, if the current temperature is not less than the target temperature and less than the first temperature, and the current humidity is less than the third humidity, it means that the current temperature is appropriate, but the current humidity is too low and humidification is required. At this time, the status of the compressor and the evaporating fan is determined to determine whether dehumidification is in progress.

[0085] Step S114, if the compressor and the evaporation fan are both in operation, turn off the compressor, turn off the evaporation fan for a delay time according to the target delay time, turn off the heater, and turn on the humidifier.

[0086] In this embodiment, if the compressor and the evaporator fan are both in operation, it means that the evaporator is being used for dehumidification. The compressor is turned off, and the evaporator fan is turned off for a delay of a target delay time to prevent the temperature and humidity from further decreasing. The heater is turned off to maintain the current temperature, and the humidifier is turned on for humidification to increase the humidity.

[0087] Step S115: if the compressor is in the off state and the evaporation fan is in the delayed off state, the evaporation fan is turned off when the target delay time is reached, the heater is turned off, and the humidifier is turned on.

[0088] In this embodiment, if the compressor is in the off state and the evaporating fan is in the delayed off state, the evaporating fan needs to be turned off when the target delay time is reached so that the air can continue to circulate in the storage cabinet for a period of time through the fan to improve the uniformity of temperature and humidity, and the heater is turned off to maintain the current temperature, and the humidifier is turned on for humidification to increase the humidity.

[0089] Step S116: if the compressor is in the off state and the evaporation fan is not in the delayed off state, turn off the evaporation fan, turn off the heater, and turn on the humidifier.

[0090] In this embodiment, if the compressor is in the off state and the evaporator fan is not in the delayed off state, it means that the evaporator fan has completed the delayed off state, the evaporator fan and the heater are turned off to maintain the current temperature, and the humidifier is turned on for humidification to increase the humidity.

[0091] When the temperature of the storage cabinet is appropriate and the humidity is very low, the compressor, evaporating fan, heater and humidifier are controlled in a corresponding manner according to the status of the compressor and the evaporating fan to increase the humidity and ensure the stability of the temperature and humidity of the storage cabinet.

[0092] In some embodiments of the present application, Figure 5 As shown, the method further comprises the following steps:

[0093] Step S117, if the current temperature is lower than a second temperature, turn off the compressor, turn on the evaporation fan, turn on the heater, and turn off the humidifier, wherein the second temperature is lower than the target temperature.

[0094] In this embodiment, if the current temperature is lower than the second temperature, it means that the current temperature is low and needs to be heated up. The compressor is turned off to prevent the temperature from further decreasing. The evaporating fan is turned on, the heater is turned on, the humidifier is turned off, and the air heated by the heater is circulated to quickly increase the temperature in the storage cabinet.

[0095] In the specific application scenario of the present application, the second temperature = target temperature - 1.

[0096] In some embodiments of the present application, Figure 6 As shown, the method further comprises the following steps:

[0097] Step S118, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is greater than the first humidity, turn off the compressor, turn on the evaporating fan after a first delay, turn off the humidifier, and after a second delay, turn on the heater intermittently according to the target start-stop strategy.

[0098] In this embodiment, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is greater than the first humidity, it means that the current temperature is low and needs to be heated, and the current humidity is high but does not need to be dehumidified, the compressor is turned off to prevent the temperature from further decreasing, and the evaporation fan is turned on after a first delay, the humidifier is turned off, and after a second delay, the heater is turned on intermittently according to the target start-stop strategy, and the air heated by the heater is circulated to increase the temperature in the storage cabinet. Among them, turning on the heater intermittently according to the target start-stop strategy can reduce the energy consumption of the heater while increasing the temperature. The target start-stop strategy can, for example, turn on the heater intermittently for 5 seconds and stop for 3 seconds.

[0099] The optional first duration may be different from the second duration, such as both being 5 minutes, or may be different from the second duration.

[0100] Step S119, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, turn off the compressor, turn on the evaporating fan after a first delay, maintain the state of the humidifier unchanged, and after the second delay, turn on the heater intermittently according to the target start-stop strategy.

[0101] In this embodiment, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, it means that the current temperature is low and needs to be heated up. The current humidity is appropriate, so the compressor is turned off to avoid further temperature drop, and the evaporating fan is turned on after a first delay, maintaining the state of the humidifier unchanged. After a second delay, the heater is turned on intermittently according to the target start and stop strategy, and the air heated by the heater is circulated to increase the temperature in the storage cabinet.

[0102] Step S120, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is less than the second humidity, turn off the compressor, turn on the evaporating fan, turn on the humidifier, and intermittently turn on the heater according to the target start-stop strategy.

[0103] In this embodiment, if the current temperature is not less than the second temperature and less than the target temperature, and the current humidity is less than the second humidity, it means that the current temperature and the current humidity are low, and heating and humidification are required. The compressor is turned off to avoid further temperature drop, the evaporating fan and the humidifier are turned on, and the heater is turned on intermittently according to the target start and stop strategy to increase the temperature and humidity in the storage cabinet.

[0104] When the temperature of the storage cabinet is low, the compressor, evaporating fan, heater and humidifier are controlled in a corresponding manner according to different humidity to increase the temperature inside the storage cabinet and ensure the stability of the temperature and humidity of the storage cabinet.

[0105] In some embodiments of the present application, Figure 7 As shown, the method further comprises the following steps:

[0106] Step S121, if the current temperature is not less than the first temperature, and the current humidity is greater than the first humidity, turn off the heater, turn on the compressor, turn on the evaporating fan, and turn off the humidifier.

[0107] In this embodiment, if the current temperature is not less than the first temperature, and the current humidity is greater than the first humidity, it means that the current temperature is high and needs to be cooled, and the current humidity is high and needs to be dehumidified. At this time, the heater is turned off, the compressor is turned on, the evaporating fan is turned on, and the humidifier is turned off to use the evaporator for dehumidification and cooling.

[0108] Step S122, if the current temperature is not less than the first temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, turn off the heater, turn on the compressor, turn on the evaporating fan, and maintain the state of the humidifier unchanged.

[0109] In this embodiment, if the current temperature is not less than the first temperature, and the current humidity is not less than the second humidity and not greater than the first humidity, it means that the current temperature is high and needs to be cooled. The current humidity is appropriate. At this time, the heater is turned off, the compressor is turned on, the evaporating fan is turned on, and the state of the humidifier is maintained unchanged so that the evaporator can be used for cooling.

[0110] Step S123, if the current temperature is not less than the first temperature, and the current humidity is less than the second humidity, turn off the heater, turn on the compressor, turn on the evaporating fan, and turn on the humidifier.

[0111] In this embodiment, if the current temperature is not less than the first temperature and the current humidity is less than the second humidity, it means that the current temperature is high and needs to be cooled, and the current humidity is low and needs to be humidified. The heater is turned off, the compressor is turned on, and the evaporating fan is turned on to use the evaporator for cooling, and the humidifier is turned on to increase the humidity.

[0112] When the temperature of the storage cabinet is high, the compressor, evaporating fan, heater and humidifier are controlled in a corresponding manner according to different humidity to reduce the temperature inside the storage cabinet and ensure the stability of the temperature and humidity of the storage cabinet.

[0113] In some embodiments of the present application, the control method of the heater includes at least one of the following:

[0114] controlling the heater according to a target start-stop strategy;

[0115] The on-time rate of the compressor is periodically obtained according to a target time interval, and the target operating voltage of the heater is determined according to the on-time rate, so that the heater operates at the target operating voltage, wherein the on-time rate is determined by the ratio of the operating time of the compressor to the operating time of the storage cabinet.

[0116] In this embodiment, the heater can be controlled in two ways. One way is to control the heater according to the target start-stop strategy. The target start-stop strategy can be to turn off the heater after running for a fixed time each time, or to turn on the heater intermittently according to the specified running time and off time. Another way is to determine the target operating voltage of the heater according to the start-up rate of the compressor, and operate the heater according to the target operating voltage. Specifically, the start-up rate is determined by the ratio of the running time of the compressor to the running time of the storage cabinet. The start-up rate of the compressor is regularly obtained according to the target time interval, and the target operating voltage of the heater is determined according to the start-up rate obtained each time, so as to realize dynamic adjustment of the heater voltage.

[0117] The heater can be controlled in two ways, which enables more flexible control of the heater.

[0118] In some embodiments of the present application, determining the target operating voltage of the heater according to the startup rate includes:

[0119] obtaining a current operating voltage of the heater;

[0120] If the on-rate is not less than the first on-rate, determining the target operating voltage according to the current operating voltage and the lowest operating voltage of the heater, so that the target operating voltage is less than the current operating voltage;

[0121] If the power-on rate is less than the first power-on rate and not less than the second power-on rate, determining the current operating voltage as the target operating voltage;

[0122] If the on-rate is less than the second on-rate and not less than zero, determining the target operating voltage according to the current operating voltage and the highest operating voltage of the heater, so that the target operating voltage is greater than the current operating voltage;

[0123] The lowest operating voltage is lower than the rated operating voltage of the heater, and the highest operating voltage is higher than the rated operating voltage of the heater.

[0124] In this embodiment, the current operating voltage of the heater is obtained, and when the heater is turned on for the first time, the heater can be started based on the rated voltage of the heater and operated at the rated voltage.

[0125] If the startup rate is not less than the first startup rate, it means that the compressor needs to run for a long time and needs to be cooled frequently. At this time, the target operating voltage is determined according to the current operating voltage and the minimum operating voltage of the heater, so that the target operating voltage is less than the current operating voltage. Specifically, half of the sum of the current operating voltage and the minimum operating voltage can be used as the target operating voltage, so that the heater can be operated at a lower power, thereby slowly increasing the temperature while reducing the power consumption of the heater.

[0126] If the startup rate is less than the first startup rate and not less than the second startup rate, the current operating voltage is determined as the target operating voltage, indicating that the operating time of the compressor is normal, so that the heater maintains the current operating voltage, thereby heating up at a normal heating rate.

[0127] If the startup rate is less than the second startup rate and is not less than zero, it means that the operating time of the compressor is short and frequent cooling is not required. The target operating voltage is determined according to the current operating voltage and the maximum operating voltage of the heater, so that the target operating voltage is greater than the current operating voltage. Specifically, half of the sum of the current operating voltage and the maximum operating voltage can be used as the target operating voltage, so that the heater can be operated at a higher power to quickly increase the temperature.

[0128] According to the start-up rate of the compressor, the target operating voltage of the heater is dynamically controlled so that the heater generates heat that matches the actual environment in the storage cabinet, thereby improving the accuracy of temperature regulation.

[0129] In the specific application scenario of the present application, the target operating voltage of the heater is V, the rated operating voltage of the heater is Vm, the minimum operating voltage of the heater is Vl, the maximum operating voltage of the heater is Vh, the target time interval is T, the start-up rate of the compressor is W, the first start-up rate is w1, and the second start-up rate is w2. Figure 8 The control process flow chart of the heater of the embodiment of the present application is shown, which includes the following process:

[0130] After the cabinet is turned on, the heater is turned on, and the rated voltage Vm of the heater is used as the target operating voltage V, V=Vm. Then the compressor start-up rate W is calculated according to the target time interval T. If W≥w1, then V'=(V+Vl) / 2, and the target operating voltage V=V' for this round. If w2≤W<w1, then V'=V, and the target operating voltage V=V' for this round. If 0≤W2<w2, then V'=(V+Vh) / 2, and the target operating voltage V=V' for this round.

[0131] The present application also provides a storage cabinet, which is controlled by the control method of the storage cabinet as described above. Fig. 9 and Fig.10 As shown, the storage cabinet includes:

The evaporation fan 40 can transport the air in the storage space 111 of the storage cabinet to the evaporator 30 and the heater 50 of the storage cabinet, and return to the storage space 111. The evaporator 30 can dehumidify and cool the air passing through after the compressor 20 is turned on, and the heater 50 can heat the air passing through after it is turned on. The heater 50 is arranged in the air duct 112 and is located at the lower part of the evaporator 30, so that the operation of the heater 50 can avoid affecting the evaporator 30, and ensure the dehumidification and cooling efficiency of the evaporator 30.

[0142] The humidifier 60 is arranged at the lower part of the cabinet 10.
