Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

It should be noted that, in the embodiments of the present invention, "of", "corresponding" and "corresponding" may be sometimes used in combination, and it should be noted that, when the difference is not emphasized, the intended meaning is consistent.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used for distinguishing the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like are not limited in number or execution order. All humidity in this application refers to relative humidity.

At present, in a high-end refrigerator product with a condenser (bottom condenser) arranged outside the bottom, a refrigerant firstly passes through the condenser and then enters a dew removing pipe to remove dew on the outer surface of the refrigerator, and meanwhile, a corresponding condensing fan is arranged on the condenser and used for blowing air to the condenser so as to fully dissipate heat of the condenser. But present condensation fan's accurate speed is either invariable or according to the ambient temperature adjustment rotational speed of refrigerator (ambient temperature is higher, the rotational speed is big more), so, though guaranteed the radiating effect of condenser, but if external ambient temperature is unchangeable, the rotational speed of condensation fan is invariable so, make the temperature that gets into the refrigerant that removes the dew pipe also can not have great change, so to the environment that ambient humidity is different, the dew removal effect that removes the dew pipe can have great difference, guarantee refrigerator surface that can not be fine is not dew, user experience is not good.

In view of the above problem, referring to fig. 1, an embodiment of the present application provides a refrigerator 01, including: the device comprises a condenser 11, a condensing fan 12, a dew removing pipe 13, an environment detection device 14 and a main control board 15; wherein, the condensing fan 12 is used for blowing air to the condenser 11; the inlet of the dew-removing pipe 13 is connected with the outlet of the condenser 11; the environment detection device 14 is used for detecting the environment temperature and the environment humidity of the refrigerator; the main control board 15 is configured to: acquiring the ambient temperature and the ambient humidity of the refrigerator through the ambient detection device 14, and determining a target operation mode of the condensing fan 12 according to the ambient temperature and the ambient humidity detected by the ambient detection device 14; the target pre-rotation mode is any one of a plurality of preset operation modes; the operation modes correspond to the environmental temperature and the environmental humidity which meet different conditions one by one; the condensing fan 12 is controlled to perform a target operation mode to adjust the temperature of the dew condensation removing duct 13.

Illustratively, referring to fig. 1, in practice, the refrigerator 01 further includes: a compressor 16 and an evaporator 17 provided in a storage chamber inside the refrigerator; the outlet of the compressor 16 is connected to the condenser 11, and the inlet of the compressor 16 is connected to the evaporator 17. When the refrigerator 01 normally performs refrigeration, the compressor 16 compresses a refrigerant (refrigerant) into high-temperature and high-pressure gas, the compressor 16 sends the high-temperature and high-pressure refrigerant to the condenser 11 to be condensed into medium-temperature and high-pressure liquid, the medium-temperature and high-pressure liquid refrigerant enters the evaporator 17 through the dew-removing pipe 13 to absorb heat and evaporate into low-temperature and low-pressure gas, and finally returns to the compressor 16 again to complete a refrigeration cycle. In particular, taking three storage chambers including a refrigerating chamber, a freezing chamber and a temperature changing chamber as an example, a piping diagram of the interior of the refrigerator provided by the embodiment of the present application can be seen with reference to fig. 2, wherein, the air outlet of the compressor 16 is connected with the inlet of the condenser 11, the outlet of the condenser 11 is connected with the inlet of the freezing dew-removing pipe 13-1 corresponding to the freezing chamber, the inlet of the variable temperature dew-removing pipe 13-2 corresponding to the variable temperature chamber and the inlet of the refrigerating dew-removing pipe 13-3 corresponding to the refrigerating chamber, the outlet of the freezing dew-removing pipe 13-1, the outlet of the variable temperature dew-removing pipe 13-2 and the outlet of the refrigerating dew-removing pipe 13-3 are respectively connected with the inlet of the freezing evaporator 17-1 corresponding to the freezing chamber, the inlet of the variable temperature evaporator 17-2 corresponding to the variable temperature chamber and the inlet of the refrigerating evaporator 17-3 corresponding to the refrigerating chamber through an electric valve 18; the outlet of the freezing evaporator 17-1, the outlet of the temperature changing evaporator 17-2 and the outlet of the refrigerating evaporator 17-3 are connected to the air inlet of the compressor 16 through an air return pipe 19; the condensing fan 12 is disposed between the compressor 16 and the condenser 11 to blow air to the condenser 11. When the refrigerator works normally, the flow direction of the refrigerant is as follows: the compressor 16 → the condenser 11 → the freezing dew-removing pipe 13-1 → the temperature-changing dew-removing pipe 13-2 → the refrigerating dew-removing pipe 13-3 → the electric valve 18 → the evaporator 17 (the refrigerating evaporator 17-1, the freezing evaporator 17-2 and the temperature-changing evaporator 17-3 are divided in three ways) → the air return pipe 19 → the compressor 16.

Optionally, in practice, the environment detection device 14 may be a temperature and humidity sensor for simultaneously detecting the environment temperature and the environment humidity of the refrigerator, or may be a temperature sensor and a humidity sensor for respectively detecting the environment temperature and the environment humidity of the refrigerator, which is not particularly limited in this application. Illustratively, and as shown in FIG. 3, the environment sensing device 14 may be disposed within a hinge box at the top of the refrigerator.

In the technical scheme provided by the embodiment of the application, because the dew removing pipe is mostly arranged near the door frame of the refrigerator, the dew on the outer surface of the refrigerator is removed through the temperature of the medium-temperature and high-pressure liquid refrigerant flowing in the dew removing pipe. And in the technical scheme that this application provided, the difference of the operation mode of condensation fan can make the difference of condenser heat dissipation capacity, so get into the temperature that removes the middle temperature high pressure liquid refrigerant of dew pipe just also different, because the operation mode is closely related with the ambient temperature and the ambient humidity of refrigerator again, so the temperature that removes the dew pipe just also has been directed against the ambient temperature and the ambient humidity of refrigerator, can play the condensation effect of preventing to the refrigerator surface.

Optionally, in practice, if the compressor of the refrigerator is started to correspondingly control the temperature of the dew removing pipe, the heat dissipation of the condenser may be insufficient, so that the refrigeration effect of each storage chamber of the refrigerator is poor, and the user experience is more affected, therefore, the precondition of correspondingly controlling the temperature of the dew removing pipe is to ensure that the refrigeration effect of each storage chamber in the refrigerator reaches the required standard (stable operation), so the main control board 15 is specifically configured as: when the storage room in the refrigerator satisfies the stable operation condition, the ambient temperature and the ambient humidity of the refrigerator are acquired by the environment detecting device 14.

Further optionally, the refrigerating effect of each storage chamber in the refrigerator meets the required standard, which generally means that the temperature in the storage chamber is already low to a certain degree and the refrigerating effect can be completed without reducing the temperature, so that the temperature sensor is arranged in the storage chamber in the refrigerator provided by the embodiment of the application and used for detecting the temperature of the storage chamber; the stable operation condition includes at least a temperature of the storage chamber being equal to or lower than a first preset temperature. For example, the first preset temperature may be a temperature lower than the temperature set by the user in the storage room, for example, the temperature set by the user is 8 ℃, and then the first preset temperature may be 5 ℃. Of course, in practice, the stable operation condition may be that other parameters that can indicate that the refrigeration effect of the storage chamber reaches the preset standard reach the preset standard, and is not limited herein.

Optionally, because there may be measurement errors in the detection effect of the environment detection device 14 in practice, and the current environment state can be accurately determined by measuring for multiple times, the main control board 15 is specifically configured to: controlling the environment detection device 14 to continuously detect the environment temperature and the environment humidity for multiple times, wherein the time interval between two continuous detections is a first preset time; and determining the target operation mode of the condensing fan 12 according to the detection result of the environment detection device 14 on the environment temperature and the environment humidity for a plurality of times. For example, the first preset time period may be 1min (for example only, and may also be other similar values), and the plurality of times may be three times (for example only, and may also be other similar values).

In another possible implementation manner, after controlling the environment detecting device 14 to continuously detect the environment temperature and the environment humidity for a plurality of times, the main control board 15 may be further configured to: determining a target operation mode of the condensing fan 12 according to an average value of the detection results of the environment detection device 14 for the environment temperature for a plurality of times and an average value of the detection results of the environment humidity for a plurality of times; for a specific judgment manner, reference may be made to the following description, as long as "the detection results of a plurality of consecutive times" is replaced with "the average value of the detection results of a plurality of consecutive times", all of "greater than" is replaced with "greater than", all of "less than" is replaced with "less than", and this scheme is not specifically described in the following. .

Optionally, the preset multiple operation modes may include: a first operation mode, a second operation mode and a third operation mode; the main control board 15 is specifically configured to:

when the detection results of the environmental temperature and the environmental humidity which are continuously detected for multiple times are determined to meet a first preset condition, determining a first operation mode as a target operation mode; the first preset condition is that the detection results of the environmental temperature for a plurality of times are all larger than the second preset temperature, and/or the detection results of the environmental humidity for a plurality of times are all smaller than the first preset humidity; for example, the second preset temperature may be 37 ℃ (for example only, and may be other similar values), and the first preset humidity may be 50% (for example only, and may be other similar values); when the ambient temperature and the ambient humidity satisfy the first preset condition, the ambient state of the refrigerator may have two conditions, one is a high-temperature harsh environment in which the ambient temperature is high (greater than the second preset temperature), and the other is a low-humidity use environment in which the ambient humidity is low (less than the first preset humidity).

When the detection results of the environmental temperature and the environmental humidity which are continuously detected for multiple times are determined to meet a second preset condition, determining a second operation mode as a target operation mode; the second preset condition is as follows: the detection results of the continuous and multiple times of the environmental temperature are all smaller than a second preset temperature, and the detection results of the continuous and multiple times of the environmental humidity are all larger than a second preset humidity; an exemplary second predetermined humidity may be 70% (for example only, and other similar values are also possible); when the ambient temperature and the ambient humidity satisfy the second preset condition, the ambient state of the refrigerator should be a high-humidity use environment in which the ambient humidity is high and condensation is easy.

When the detection results of the environmental temperature and the environmental humidity which are continuously detected for multiple times are determined to meet a third preset condition, determining a third operation mode as a target operation mode; the third preset condition is as follows: the detection results of the continuous and multiple times of the environment temperature are all smaller than the second preset temperature, and the detection results of the continuous and multiple times of the environment humidity are all larger than the first preset humidity and are all smaller than the second preset humidity. When the ambient temperature and the ambient humidity satisfy the third preset condition, the ambient state of the refrigerator should be a medium-humidity use environment with moderate ambient humidity.

Further optionally, the first operating mode at least comprises: the condensing fan continuously operates when a compressor of the refrigerator works; therefore, when the main control board 15 determines that the first operation mode is the target operation mode, the main control board 15 is specifically configured to: the condensing fan 12 is controlled to continuously operate while the compressor 16 of the refrigerator is operated. Because the two corresponding conditions of the first operation mode are a high-temperature harsh environment and a low-humidity environment respectively, for the high-temperature harsh environment, because the control of the refrigerator on the compressor is in relation with the temperature of the external environment, when the environment temperature is higher, the compressor can increase the power for better ensuring the refrigeration effect in the refrigerator, the temperature of the high-temperature high-pressure refrigerant gas generated by the compressor is higher, the temperature of the refrigerant entering the dew removing pipe after the heat dissipation of the condenser is higher, and the anti-condensation effect of the outer surface of the refrigerator can be ensured, so for the refrigerator in the high-temperature harsh environment, the condensing fan does not need to be specially controlled, and the temperature of the refrigerant in the dew removing pipe can achieve the better anti-condensation effect only by controlling the compressor to continuously operate at a preset rotating speed when the compressor operates; for a low-humidity environment, because the environment humidity is very low, the refrigerator is not easy to generate condensation, and the temperature of the refrigerant flowing out of the condenser is enough to achieve the condensation preventing effect, the condensation fan does not need to be specially controlled at the moment, and the compressor is controlled to continuously run at a preset rotating speed only when running, so that the temperature of the refrigerant in the condensation removing pipe can achieve the good condensation preventing effect.

Further optionally, the second operation mode at least comprises: when the compressor of the refrigerator works, the condensing fan stops for a third preset time when running for a second preset time; the third preset time length is longer than the second preset time length; when the main control board 15 determines that the second operation mode is the target operation mode, the main control board is configured to: controlling the condensing fan 12 to stop for a third preset time period every second preset time period when the compressor 16 of the refrigerator works; the third preset time is longer than the second preset time. For example, the second preset duration may be 5min (for example only, and other similar values are also possible), and the third preset duration may be 10min (for example only, and other similar values are also possible). Because the environment state corresponding to the second operation mode is a high-humidity use environment, the refrigerator is easy to generate condensation under the environment state, so that the condensation can achieve a better condensation preventing effect only by the high temperature of the condensation removing pipe under the condition, at the moment, the condensation fan is controlled to operate for a certain time (second preset time) when the compressor operates, then the condensation fan is stopped for a longer time (third preset time), and then the circulating operation process is carried out; and when the condensation fan moves, the radiating effect of condenser is better, then the condenser flows in the temperature that removes the dew pipe also be lower, and when the condensation fan stopped, the radiating effect of condenser is relatively poor, then the condenser flows in the temperature that removes the dew pipe also be higher, so when the operation mode that stops again according to the operation through control condensation fan, can make the refrigerant in removing the dew pipe be higher at the average temperature of the in-process of compressor operation, just also can guarantee its better condensation effect of preventing. For example, the verification chart of the experimental verification of the temperature of the dew-removing pipe in the second operation mode provided by the above embodiment is shown in fig. 4, in which the horizontal direction represents a time axis and the vertical direction represents a temperature axis, and it can be seen that when the condensing fan operates in the second operation mode, the temperature of the dew-removing pipe has a certain fluctuation, and the average temperature thereof is inevitably higher than the temperature thereof when the condensing fan continuously operates (a part of the curve corresponding to the lower temperature is approximately regarded as the temperature curve of the dew-removing pipe when the condensing fan continuously operates).

Further optionally, the third operating mode at least comprises: when the compressor of the refrigerator works, the condensing fan stops for a fourth preset time when running for a fourth preset time; therefore, when the main control board determines that the third operation mode is the target operation mode, the main control board is specifically configured to: and controlling the condensing fan to stop for a fourth preset time when the condensing fan operates for the fourth preset time when a compressor of the refrigerator works. Illustratively, the fourth preset duration may be 5mim (for example only, and other similar values are also possible). In practice, the main control board may further control the condensing fan to stop for a target preset time that is not approximately equal to the fourth preset time every time the fourth preset time is operated when the compressor operates, for example, when the fourth preset time is 5min, the target preset time may be 4min or 6 min. Since the environment state corresponding to the third operation mode is a medium-humidity environment, which has a low environmental humidity relative to the high-humidity environment but is not too low, the refrigerator may be prone to dew condensation in the medium-humidity environment, but the probability of dew condensation is lower than that in the high-humidity environment, and therefore, in this case, the temperature of the dew removing pipe needs to be increased, but does not need to be increased as high as that in the high-humidity environment; therefore, in this case, although the condensing fan needs to be controlled to operate for a certain time (the fourth preset time period) and then stop for a certain time (the fourth preset time period), the stop time does not need to be longer than the operation time in the high-humidity environment, and therefore, when the environment state is the medium-humidity environment, the main control board controls the condensing fan to execute the third operation mode (the fourth preset time period is stopped when the compressor operates without operating for the fourth preset time period), so that the temperature of the dew removing pipe can reach the requirement of fully preventing condensation.

It should be noted that, the fact that the detection results of the environmental temperature for a plurality of consecutive times are all equal to the second preset temperature may be attributed to the fact that the detection results of the environmental temperature for a plurality of consecutive times are all less than the second preset temperature, or may also be attributed to the fact that the detection results of the environmental temperature for a plurality of consecutive times are all greater than the second preset temperature, which is not limited herein. The same principle is that the detection results of the environmental humidity continuously for a plurality of times are equal to the first preset humidity and the environmental humidity is equal to the second preset humidity.

Further optionally, because the environmental state of the refrigerator may change after a certain time, the operation mode needs to be determined again after the main control board controls the condensing fan to operate in a certain operation mode for a certain time to ensure that the temperature of the dew removing pipe changes in time according to the environmental state, so the main control board 15 is further configured to: when the condensing fan 12 is operated in the target operation mode for the sixth preset time period, the environment temperature and the environment humidity of the refrigerator are obtained again through the environment detection device, and the target operation mode of the condensing fan is determined according to the obtained environment temperature and environment humidity. For example, the sixth preset time period may be 3h (for example only, other values may also be used, and is determined according to actual conditions).

Further optionally, because the main control board determines that the whole process of the operation of the condensing fan is relatively consuming computing resources according to the ambient temperature and the ambient humidity, and the ambient state of the condensing fan does not necessarily change after the condensing fan is operated for the sixth preset time period in an accumulated manner, if the target operation mode of the condensing fan is determined according to the environment temperature and the ambient humidity acquired again after the condensing fan is operated for the sixth preset time period in an accumulated manner every time, some unnecessary computing resources are wasted, so the main control board is configured to: when the condensing fan 12 is operated in the target operation mode for the sixth preset time period, the environment temperature and the environment humidity of the refrigerator are acquired again through the environment detection device 14; when it is determined that the conditions that the reacquired ambient temperature and ambient humidity satisfy do not correspond to the target operation mode, the target operation mode of the condensing fan 12 is determined according to the reacquired ambient temperature and ambient humidity. Therefore, only when the situation that the environment state changes after the condensation fan is operated for the sixth preset time in an accumulated mode when the condensation fan executes the target operation mode is determined, the main control board determines the target operation mode of the condensation fan according to the acquired environment temperature and environment humidity, and computing resources are saved. Of course, in practice, when the main control board determines that the condensing fan performs the target operation mode after running for the sixth preset time in an accumulated manner, and determines the target operation mode of the condensing fan according to the environment temperature and the environment humidity acquired again, it may be determined whether the target operation mode satisfies the environment state corresponding to another operation mode different from the last determined target operation mode only according to the environment temperature and the environment humidity acquired again, so as to determine the target operation mode required to be determined at present more quickly.
