[0033] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0034] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0035] Combination Figures 1 to 3 As shown, Figure 1 It is a structural schematic diagram of a dew removal device provided in an embodiment of the present disclosure. Figure 2 It is a structural schematic diagram of a refrigerant flowing through a dehumidification pipe in a dehumidification device provided in an embodiment of the present disclosure. Figure 3It is a structural schematic diagram of a dehumidification device provided by an embodiment of the present disclosure in which the refrigerant does not flow through the dehumidification pipe.

[0036] The dehumidification device comprises a refrigerant circulation pipeline 1, a dehumidification pipe 2, a fan 3 and a solenoid valve 4. The refrigerant circulation pipeline 1 comprises a compressor 5, a condenser 6 and an evaporator 7.

[0037] The refrigerant circulation pipeline 1 is configured to perform refrigeration using the refrigerant discharged when the compressor 5 is in operation. The dew-removing pipe 2 is arranged between the condenser 6 and the evaporator 7, and the dew-removing pipe 5 is configured to be in a working state when the refrigerant flows through the dew-removing pipe. It is in a non-working state when no refrigerant flows through the dew-removing pipe. The fan 3 is arranged on one side of the condenser 6, and the fan 3 is configured to be controlled to be turned on or off. When the fan is turned on, it is used to dissipate heat from the condenser 6. The solenoid valve 4 is arranged between the condenser 6 and the dew-removing pipe 2, and the solenoid valve 4 is configured to be controlled to open the first valve or the second valve.

[0038] A refrigerant pipeline is provided between the condenser 6 and the evaporator 7. One end of the refrigerant pipeline is connected to the evaporator 7, and the other end is connected to the second valve of the solenoid valve 4. When the first valve is opened, the solenoid valve 4 allows the refrigerant to flow through the dew-removing pipe 2. When the second valve is opened, the solenoid valve 4 prevents the refrigerant from flowing through the dew-removing pipe 2. In this way, the refrigerant flow direction is controlled by providing a solenoid valve between the condenser and the dew-removing pipe. The dew-removing pipe is in a working state only when the refrigerant flows through it, and is in a non-working state when no refrigerant flows through it. Condensation prevention can be performed more accurately. At the same time, the heat of the dew-removing pipe can be reduced by dissipating heat from the condenser through the fan. Thereby reducing the heat load of the refrigerator, and thus achieving more accurate dew prevention while saving energy.

[0039] Figure 2 In the refrigerator, when the first valve of the solenoid valve 4 is open, the refrigerant in the dehumidification device flows as follows: the compressor 5 discharges the refrigerant when it is running, and the refrigerant flows through the condenser 6 and then enters the dehumidification pipe 2 through the first valve of the solenoid valve 4. Then, the refrigerant passes through the evaporator 7 and returns to the compressor 5.

[0040] Figure 3 In the refrigerator, when the refrigerator is refrigerating, when the second valve of the solenoid valve 4 is opened, the flow direction of the refrigerant in the dew removal device is: the refrigerant is discharged when the compressor 5 is running, the refrigerant flows through the condenser 6 and then enters the evaporator 7 through the second valve of the solenoid valve 4, and then returns to the compressor 5.

[0041] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for controlling a dew removal device, comprising:

[0042] Step S401: The refrigerator obtains the ambient humidity.

[0043] Step S402: The refrigerator controls the solenoid valve and the fan according to the ambient humidity.

[0044] By adopting the method for controlling the dew removal device provided in the embodiment of the present disclosure, a solenoid valve is added between the dew removal pipe and the condenser, and the ambient humidity is collected to control the solenoid valve and the fan. This allows anti-condensation control to be performed at the appropriate time under different environments, thereby achieving more accurate anti-condensation while saving energy.

[0045] Furthermore, the refrigerator controls the solenoid valve and the fan according to the ambient humidity, including: the refrigerator matches the solenoid valve state and the fan duty cycle corresponding to the ambient humidity from a preset database, and the preset database stores the corresponding relationship between the ambient humidity, the solenoid valve state and the fan duty cycle. The solenoid valve state is used to characterize whether the solenoid valve opens the first valve or the second valve. The solenoid valve and the fan are controlled respectively according to the solenoid valve state and the fan duty cycle.

[0046] In some embodiments, when the ambient humidity RH is ≥ 90%, the solenoid valve state corresponding to the ambient humidity RH is matched from the preset database as "first valve open" and the fan duty cycle is "≤ 50%". This can ensure that no condensation occurs in the refrigerator in a high humidity environment. At the same time, the fan duty cycle ≤ 50% can reduce the heat dissipation of the condenser and increase the heat of the dehumidification pipe. Thereby improving the anti-condensation effect.

[0047] In some embodiments, when the ambient humidity RH of the refrigerator is within the range of 75%<RH<90%, the solenoid valve state corresponding to the ambient humidity RH is matched to "first valve open" and the fan duty cycle is matched to "random value" from the preset database. This can ensure that condensation does not occur in the refrigerator in a high humidity environment.

[0048] In some embodiments, when the ambient humidity RH of the refrigerator is within the range of 60%<RH≤75%, the state of the solenoid valve corresponding to the ambient humidity RH is matched from the preset database as "the first valve is open" during the period from the start of the compressor to the end of the refrigeration of the refrigerator's refrigerator compartment, and "the second valve is open" during the period from the end of the refrigeration of the refrigerator's refrigerator compartment and the freezer compartment is refrigerated separately to the compressor stopping, and the fan duty cycle is "≥75%". Or, when the ambient humidity RH of the refrigerator is within the range of 60%<RH≤75%, the state of the solenoid valve corresponding to the ambient humidity RH is matched from the preset database as "the second valve is open" during the period from the start of the compressor to the end of the refrigeration of the refrigerator's refrigerator compartment, and "the first valve is open" during the period from the end of the refrigeration of the refrigerator's refrigerator compartment and the freezer compartment is refrigerated separately to the compressor stopping, and the fan duty cycle is "≥75%". In this way, during the process from the start of the compressor to the shutdown, the refrigerant flow direction takes into account both flow directions under the control of the solenoid valve, and anti-condensation is achieved while saving energy.

[0049] In some embodiments, when the ambient humidity RH is ≤60%, the refrigerator matches the solenoid valve state corresponding to the ambient humidity RH as "second valve open" and the fan duty cycle as "≥75%" from the preset database. In this way, when the ambient humidity RH is ≤60%, there is no need to consider anti-condensation, and the refrigerant does not flow through the dew removal pipe, which reduces the heat load of the dew removal pipe on the refrigerator. The high duty cycle cooling fan dissipates heat from the condenser, making the refrigerator fully energy-saving. Reduce the heat load of the refrigerator at normal temperature, improve energy efficiency, and achieve energy saving.

[0050] Furthermore, the refrigerator controls the solenoid valve and the fan according to the ambient humidity, including: the refrigerator obtains the ambient temperature, and obtains the dew point temperature according to the ambient temperature and the ambient humidity. The solenoid valve and the fan are controlled according to the dew point temperature. In this way, the control of the solenoid valve and the fan by the dew point temperature can meet the dew removal needs in different environments. According to the different dew point temperatures of the environment in which the refrigerator is located, the dew removal pipe achieves dew removal while saving energy by matching the refrigerant flow direction and the fan duty cycle. Therefore, regardless of different working areas or changes in seasons, the dew removal device and the method for controlling the dew removal device provided in the present application can adapt to the environment in which the refrigerator is located.

[0051] Furthermore, the refrigerator obtains the dew point temperature according to the ambient temperature and the ambient humidity, including: the refrigerator matches the dew point temperature corresponding to the ambient temperature and the ambient humidity from a preset database. The preset database stores the correspondence between the ambient temperature, the ambient humidity and the dew point temperature.

[0052] Furthermore, the refrigerator controls the solenoid valve and the fan according to the dew point temperature, including: the refrigerator obtains the temperature difference between the dew point temperature and a preset temperature threshold, obtains the solenoid valve state and the fan duty cycle corresponding to the temperature difference, and controls the solenoid valve and the fan respectively according to the solenoid valve state and the fan duty cycle.

[0053] Furthermore, the refrigerator controls the solenoid valve and the fan according to the dew point temperature, including: the refrigerator obtains a comparison result between the dew point temperature and a preset temperature threshold, obtains the solenoid valve state according to the comparison result, and obtains the fan duty cycle according to the ambient humidity. The solenoid valve and the fan are controlled respectively according to the solenoid valve state and the fan duty cycle.

[0054] Furthermore, the refrigerator obtains the fan duty cycle according to the ambient humidity, including: the refrigerator matches the fan duty cycle corresponding to the ambient humidity from a preset database. The preset database stores the corresponding relationship between the ambient humidity and the fan duty cycle.

[0055] Furthermore, the refrigerator obtains the state of the solenoid valve according to the comparison result, including: when the comparison result is that the dew point temperature is greater than or equal to the preset temperature threshold, the refrigerator determines that the state of the solenoid valve is to open the first valve. And / or, when the comparison result is that the dew point temperature is less than the preset temperature threshold, the state of the solenoid valve is determined to open the second valve. In this way, controlling the solenoid valve by the temperature difference can meet the dew removal needs in different environments. According to the temperature difference of the environment in which the refrigerator is located, the dew removal pipe removes moisture or saves energy by matching the refrigerant flow direction. Therefore, regardless of the different working areas or the changes in seasons, the dew removal device and the method for controlling the dew removal device provided in the present application can adapt to the environment in which the refrigerator is located.

[0056] Combination Figure 5 As shown, the embodiment of the present disclosure provides a method for controlling a dew removal device, comprising:

[0057] Step S501: The refrigerator obtains ambient humidity and ambient temperature.

[0058] Step S502: The refrigerator obtains the dew point temperature according to the ambient temperature and ambient humidity.

[0059] Step S503: the refrigerator obtains the temperature difference between the dew point temperature and a preset temperature threshold.

[0060] Step S504, the refrigerator obtains the solenoid valve state and fan duty cycle corresponding to the temperature difference.

[0061] Step S505, the refrigerator controls the solenoid valve and the fan respectively according to the solenoid valve state and the fan duty cycle.

[0062] By adopting the method for controlling the dew removal device provided by the embodiment of the present disclosure, a solenoid valve is added between the dew removal pipe and the condenser, the dew point temperature is determined by collecting the ambient humidity and the ambient temperature, and the solenoid valve and the fan are controlled according to the temperature difference between the dew point temperature and the preset temperature threshold, so that more accurate anti-condensation can be achieved while saving energy. At the same time, it can meet the dew removal needs in different environments, and the dew removal is controlled with matching solenoid valve states and fan duty cycles when the temperature difference is different. Whether it is different working areas or changes in seasons, it can adapt to the environment where the refrigerator is located.
