Description

Dew removal device, method for controlling dew removal device, device, and refrigerator

[0001] This application is based on the Chinese patent application with application number 202311126230.8 and application date September 1, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0002] The present application relates to the technical field of refrigerator dehumidification control, for example, to a dehumidification device and a method, device, and refrigerator for controlling the dehumidification device. Background Art

[0003] Currently, most refrigerators have a dew duct to prevent condensation at the junction of the refrigerator's front panel and door seal under high temperature and humidity. The dew duct acts as a part of the condenser, and the heat it dissipates increases the refrigerator's heat load, further increasing its power consumption.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] In related art, regardless of whether condensation prevention is required, the de-condensation pipe continues to heat up during refrigerator cooling, increasing the refrigerator's heat load, which in turn increases the compressor's operating time and energy consumption. However, completely omitting the de-condensation pipe for energy conservation can lead to condensation leaking from the refrigerator in homes with high temperatures and high humidity. This makes it difficult to achieve both energy conservation and accurate condensation prevention.

[0006] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application.

A fan is arranged on one side of the condenser, and the fan 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. A solenoid valve is arranged between the condenser and the dew removal pipe, and the solenoid valve is configured to be controlled to open a first valve or a second valve; when the first valve is opened, the solenoid valve allows the refrigerant to flow through the dew removal pipe; when the second valve is opened, the solenoid valve prevents the refrigerant from flowing through the dew removal pipe.

[0011] In some embodiments, the method for controlling a dehumidification device includes: obtaining ambient humidity, and controlling a solenoid valve and a fan according to the ambient humidity.

[0012] In some embodiments, controlling a solenoid valve and a fan based on ambient humidity includes matching a solenoid valve state and a fan duty cycle corresponding to the ambient humidity from a preset database. The preset database stores a correspondence between ambient humidity, solenoid valve state, and fan duty cycle. The solenoid valve state indicates whether the solenoid valve is opening a first valve or a second valve. The solenoid valve and the fan are controlled based on the solenoid valve state and the fan duty cycle.

[0013] In some embodiments, controlling the solenoid valve and the fan according to the ambient humidity includes: obtaining the ambient temperature, obtaining the dew point temperature according to the ambient temperature and the ambient humidity, and controlling the solenoid valve and the fan according to the dew point temperature.

[0014] In some embodiments, obtaining the dew point temperature based on the ambient temperature and ambient humidity includes: matching the dew point temperature corresponding to the ambient temperature and ambient humidity from a preset database; the preset database stores the correspondence between the ambient temperature, ambient humidity and dew point temperature.

[0015] In some embodiments, controlling the solenoid valve and the fan based on the dew point temperature includes: obtaining a temperature difference between the dew point temperature and a preset temperature threshold, obtaining a solenoid valve state and a fan duty cycle corresponding to the temperature difference, and controlling the solenoid valve and the fan based on the solenoid valve state and the fan duty cycle.

The solenoid valve and the fan are controlled based on the solenoid valve state and the fan duty cycle, respectively.

[0017] In some embodiments, obtaining the solenoid valve state based on the comparison result includes: if the comparison result shows that the dew point temperature is greater than or equal to a preset temperature threshold, determining that the solenoid valve state is to open the first valve; and / or if the comparison result shows that the dew point temperature is less than the preset temperature threshold, determining that the solenoid valve state is to open the second valve.

[0020] The dehumidification device, method, device, and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects: a refrigerant circulation pipeline includes a compressor, a condenser, and an evaporator, and the refrigerant circulation pipeline is configured to utilize refrigerant discharged from the compressor for cooling. A dehumidification pipe is disposed between the condenser and the evaporator. The dehumidification pipe is configured to operate when refrigerant flows through the dehumidification pipe and / or to be inoperative when refrigerant does not flow through the dehumidification pipe. A fan is disposed on one side of the condenser and is configured to be controlled to be turned on or off. When the fan is turned on, it dissipates heat from the condenser. A solenoid valve is disposed between the condenser and the dehumidification pipe and is configured to control the opening of either a first valve or a second valve. When the first valve is open, the solenoid valve allows refrigerant to flow through the dehumidification pipe. When the second valve is open, the solenoid valve prevents refrigerant from flowing through the dehumidification pipe. Thus, by disposing the solenoid valve between the condenser and the dehumidification pipe to control the refrigerant flow direction, the dehumidification pipe operates only when refrigerant flows through it and is inoperative when refrigerant does not flow through it. It can prevent condensation more accurately. At the same time, the fan dissipates heat from the condenser, reducing the heat in the dehumidification pipe. This reduces the heat load of the refrigerator, thus achieving more accurate condensation prevention while saving energy.

[0030] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The accompanying drawings are for reference only and are not used to limit the embodiments of the present disclosure.

However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0031] In the description and claims of the embodiments of the present disclosure, as well as in the accompanying drawings, the terms "first," "second," and the like are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate to describe the embodiments of the present disclosure herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0032] Unless otherwise stated, the term "plurality" means two or more.

[0033] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0034] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0035] 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.

[0036] In conjunction with Figures 1 to 3, Figure 1 is a schematic diagram of the structure of a dehumidification device provided in an embodiment of the present disclosure. Figure 2 is a schematic diagram of the structure of a dehumidification device provided in an embodiment of the present disclosure in which refrigerant flows through a dehumidification pipe. Figure 3 is a schematic diagram of the structure of a dehumidification device provided in an embodiment of the present disclosure in which refrigerant does not flow through a dehumidification pipe.

[0037] The dehumidification device includes a refrigerant circulation pipeline 1, a dehumidification pipe 2, a fan 3 and a solenoid valve 4. The refrigerant circulation pipeline 1 includes a compressor 5, a condenser 6 and an evaporator 7.

[0038] The refrigerant circulation pipeline 1 is configured to utilize the refrigerant discharged by the compressor 5 for cooling. The dew-removing pipe 2 is disposed between the condenser 6 and the evaporator 7. The dew-removing pipe 5 is configured to operate when refrigerant flows through it. It is inoperative when no refrigerant flows through it. A fan 3 is disposed on one side of the condenser 6 and is configured to be controlled to open or close. When turned on, the fan 3 dissipates heat from the condenser 6. A solenoid valve 4 is disposed between the condenser 6 and the dew-removing pipe 2. The solenoid valve 4 is configured to control the opening of either the first valve or the second valve.

[0039] 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 of the solenoid valve 4 is open, the refrigerant flows through the dew-removing pipe 2. When the second valve of the solenoid valve 4 is open, the refrigerant does not flow through the dew-removing pipe 2. In this way, by providing a solenoid valve between the condenser and the dew-removing pipe to control the refrigerant flow direction, the dew-removing pipe is only in operation when refrigerant flows through it, and is inoperative when no refrigerant flows through it. This allows for more accurate condensation prevention. At the same time, the fan dissipates heat from the condenser, reducing the heat in the dew-removing pipe. This reduces the heat load of the refrigerator, thereby achieving more accurate condensation prevention while saving energy.

[0040] In Figure 2, when the refrigerator is cooling, with the first valve of solenoid valve 4 open, the refrigerant in the dehumidification device flows as follows: the compressor 5 discharges the refrigerant, which then flows through the condenser 6, the first valve of solenoid valve 4, and into the dehumidification pipe 2. The refrigerant then passes through the evaporator 7 and returns to the compressor 5.

[0041] In Figure 3, when the refrigerator is refrigerating, when the second valve of the solenoid valve 4 is open, 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, enters the evaporator 7 through the second valve of the solenoid valve 4, and then returns to the compressor 5.

[0042] 4 , an embodiment of the present disclosure provides a method for controlling a dew removal device, including:

[0043] Step S401: The refrigerator obtains the ambient humidity.

[0044] In step S402, the refrigerator controls the solenoid valve and the fan according to the ambient humidity.

[0045] By adopting the method for controlling the de-condensation device provided in the embodiment of the present disclosure, by adding a solenoid valve between the de-condensation pipe and the condenser, and collecting the ambient humidity to control the solenoid valve and the fan, anti-condensation control can be performed at the appropriate time in different environments, thereby achieving more accurate anti-condensation while saving energy.

[0046] Furthermore, the refrigerator controls the solenoid valve and fan based on the ambient humidity, including: the refrigerator matches the solenoid valve state and fan duty cycle corresponding to the ambient humidity from a preset database, wherein the preset database stores the correspondence between the ambient humidity, the solenoid valve state, and the fan duty cycle. The solenoid valve state indicates whether the solenoid valve is opening the first valve or the second valve. The solenoid valve and fan are controlled according to the solenoid valve state and the fan duty cycle.

[0047] In some embodiments, when the ambient humidity is ≥ 90%, the refrigerator uses a preset database to match the solenoid valve state to "first valve open" and the fan duty cycle to "≤ 50%" corresponding to the ambient humidity. This prevents condensation in high-humidity environments. Furthermore, a fan duty cycle of ≤ 50% reduces heat dissipation in the condenser and increases heat dissipation in the dehumidification pipe, thereby improving condensation prevention.

[0048] 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 a preset database. This ensures that condensation does not occur in the refrigerator even in high-humidity environments.

[0049] In some embodiments, when the ambient humidity (RH) of the refrigerator is within the range of 60% < RH ≤ 75%, the solenoid valve state corresponding to the ambient humidity (RH) is matched from a preset database to: "first valve open" from the moment the compressor starts to the end of cooling the refrigerator's refrigerator compartment; "second valve open" from the end of cooling the refrigerator's refrigerator compartment and the freezer compartment alone until the compressor stops; and the fan duty cycle is "≥75%." Alternatively, when the ambient humidity (RH) of the refrigerator is within the range of 60% < RH ≤ 75%, the solenoid valve state corresponding to the ambient humidity (RH) is matched from a preset database to: "second valve open" from the moment the compressor starts to the end of cooling the refrigerator's refrigerator compartment; "first valve open" from the end of cooling the refrigerator's refrigerator compartment and the freezer compartment alone until the compressor stops; and the fan duty cycle is "≥75%." In this way, from the time the compressor starts to the time it stops, the refrigerant flows in both directions under the control of the solenoid valve, saving energy while preventing condensation.

[0050] In some embodiments, when the ambient humidity is ≤ 60%, the refrigerator matches the solenoid valve state to "second valve open" and the fan duty cycle to "≥ 75%" from a preset database. This eliminates the need for condensation prevention when the ambient humidity is ≤ 60%, and refrigerant does not flow through the de-condensation pipe. This reduces the heat load on the refrigerator, and combined with the high-duty-cycle cooling fan's heat dissipation from the condenser, the refrigerator achieves significant energy savings. This reduces the refrigerator's heat load at room temperature, improving energy efficiency and achieving energy savings.

[0051] 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, controlling 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 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 embodiments of the present disclosure can adapt to the environment in which the refrigerator is located.

[0052] Furthermore, the refrigerator obtains the dew point temperature based on the ambient temperature and ambient humidity, including: the refrigerator matches the dew point temperature corresponding to the ambient temperature and ambient humidity from a preset database. The preset database stores the correspondence between the ambient temperature, ambient humidity, and dew point temperature.

[0053] 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 according to the solenoid valve state and the fan duty cycle respectively.

[0054] Furthermore, the refrigerator controls the solenoid valve and the fan based on the dew point temperature, including: obtaining a comparison result between the dew point temperature and a preset temperature threshold, obtaining a solenoid valve state based on the comparison result, and obtaining a fan duty cycle based on the ambient humidity. The solenoid valve and the fan are controlled according to the solenoid valve state and the fan duty cycle, respectively.

[0055] Furthermore, the refrigerator obtains a 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 a correspondence between the ambient humidity and the fan duty cycle.

[0056] 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 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 dew 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 by the embodiment of the present disclosure can adapt to the environment in which the refrigerator is located.

[0057] 5 , an embodiment of the present disclosure provides a method for controlling a dew removal device, including:

[0058] Step S501: The refrigerator obtains ambient humidity and ambient temperature.

[0059] In step S502, the refrigerator obtains the dew point temperature according to the ambient temperature and humidity.

[0060] Step S503: The refrigerator obtains a temperature difference between the dew point temperature and a preset temperature threshold.

[0061] In step S504, the refrigerator obtains the solenoid valve state and fan duty cycle corresponding to the temperature difference.

[0062] In step S505 , the refrigerator controls the solenoid valve and the fan according to the solenoid valve state and the fan duty cycle.

[0063] The method for controlling the dehumidification device provided by the embodiment of the present disclosure is adopted. By adding a solenoid valve between the dehumidification pipe and the condenser, the dew point temperature is determined by collecting the ambient humidity and 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, it is possible to achieve more accurate anti-condensation while saving energy. At the same time, it can meet the dehumidification needs in different environments and control the dehumidification 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 in which the refrigerator is located.

The processor 604 can call the logic instructions in the memory 601 to execute the method for controlling the dew removal device of the above embodiment.

[0065] By adopting the control device for the de-condensation device provided in the embodiment of the present disclosure, by adding a solenoid valve between the de-condensation pipe and the condenser, and collecting the ambient humidity to control the solenoid valve and the fan, anti-condensation control can be performed at the appropriate time under different environments, thereby achieving more accurate anti-condensation while saving energy.

[0066] In addition, the logic instructions in the memory 601 can be implemented in the form of software functional units and can be stored in a computer-readable storage medium when sold or used as an independent product.
