Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, in particular to a refrigerator control method and a refrigerator. Background Art

[0002] In recent years, affected by the epidemic, users' demand for large-capacity refrigerators has increased significantly. As the functional areas of refrigerators become more and more diverse, the ingredients in users' refrigerators are not limited to fruits, vegetables, and meats. More ingredients are put into the refrigerator, such as breast milk, milk powder, wild delicacies, tea, medicines, cosmetics...

[0003] In this case, once the refrigerator has problems such as poor refrigeration or non-refrigeration, it may cause damage to the ingredients in the user's refrigerator, causing huge losses to the user and leading to user complaints.

[0004] The condensation and heat dissipation methods of large-capacity refrigerators are usually divided into three types: side plate condenser heat dissipation, bottom condenser heat dissipation, and side plate condenser heat dissipation + bottom condenser heat dissipation; for the latter two heat dissipation methods, in autumn and winter, when the heating is turned on in the user's home, the indoor environmental temperature is usually between 18°C and 30°C. To keep the indoor ventilation, it is necessary to often open the windows for ventilation; when the windows are opened in winter, the outside cold air will enter the room, and the cold air will sink and gather at the bottom of the room, resulting in the temperature at the bottom of the position where the refrigerator is located being much lower than the temperature at the top, and even the temperature difference being more than 10°C. Due to the large environmental temperature difference between the upper and lower parts of the position where the refrigerator is located, the amount of liquid refrigerant entering the evaporator will be reduced, and the vaporization heat absorption capacity will be reduced, resulting in poor refrigeration or non-refrigeration of the refrigerator.

[0005] In addition, the control logic of most existing refrigerators is that the condensation fan does not work at low ambient temperatures (there are differences in settings for different products, such as below 7°C or below 13°C). Usually, the ambient temperature sensor of the refrigerator is set around the top of the refrigerator and cannot sense the actual ambient temperature around the bottom of the refrigerator, resulting in the condensation fan of the refrigerator being controlled to operate according to a higher ambient temperature working condition.

[0006] If the operation of the condensation fan introduces air at a lower ambient temperature to condense the bottom condenser, it will cause a reduction in the gas-liquid two-phase refrigerant entering the capillary tube, thereby reducing the vaporization heat absorption capacity of the evaporator, and the refrigerator will have problems such as poor refrigeration or non-refrigeration.

[0007] Therefore, it is necessary to study a refrigerator control method and a refrigerator to solve the above problems. Summary of the Invention

[0008] The present invention aims to provide an easy-to-implement, simple and convenient refrigerator control method.

[0009] To achieve the above objectives, an embodiment of the present invention provides a refrigerator control method, including:

[0010] Obtain the continuous operation time t of the refrigerator compressor 连续 , and judge t 连续 whether it satisfies t 连续 ≥t 预设1 , where t 预设1 is the first preset threshold for the continuous operation of the compressor, which is set according to the refrigeration rate of the refrigerator in the normal refrigeration mode;

[0011] When t 连续 satisfies t 连续 ≥t 预设1 , obtain the compartment temperature T of the storage compartment of the refrigerator 间室 and the evaporation temperature T at the evaporator of the refrigerator 蒸发 , and judge the difference T 间室 between the compartment temperature T 蒸发 and the evaporation temperature T 间室 -T 蒸发 whether it satisfies T 间室 -T 蒸发 <T 预设1 , where T 预设1 is the minimum temperature difference threshold that the compartment temperature T 间室 and the evaporation temperature T 蒸发 can reach in the normal refrigeration mode of the refrigerator;

[0012] When T 间室 -T 蒸发 satisfies T 间室 -T 蒸发 <T 预设1 , set the refrigerator to enter the "condenser fan shutdown mode", where the refrigerator entering the "condenser fan shutdown mode" means that the condenser fan of the refrigerator stops working.

[0013] As a further improvement of an embodiment of the present invention, after the refrigerator enters the "condenser fan shutdown mode", judge whether the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 , where the target refrigeration temperature T 目标 refers to the target refrigeration temperature value set by the user to be reached;

[0014] When the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 , set the compressor to stop, and set the refrigerator to exit the "condenser fan shutdown mode", where the refrigerator exiting the "condenser fan shutdown mode" means that the condenser fan resumes its working state in the normal refrigeration mode of the refrigerator.

[0015] As a further improvement of an embodiment of the present invention, when the compartment temperature T 间室 does not reach the target refrigeration temperature T 目标When the temperature of the compartment T 间室 and the evaporation temperature T 蒸发 the difference T 间室 -T 蒸发 Whether it satisfies T 间室 -T 蒸发 ≥T 预设2 , where T 预设2 >T 预设1 ;

[0016] When the difference T 间室 between the temperature of the compartment T 蒸发 and the evaporation temperature T 间室 -T 蒸发 satisfies T 间室 -T 蒸发 ≥T 预设2 obtain the shutdown time t 停机 of the condensing fan, and judge whether the shutdown time t 停机 satisfies t 停机 ≥t 预设3 , where t 停机 starts counting from when the refrigerator enters the "condensing fan shutdown mode", and t 预设3 is the third preset time, which is the first threshold for setting the shutdown time of the condensing fan on the premise of ensuring the refrigeration depth of the refrigerator;

[0017] When the shutdown time t 停机 satisfies t 停机 ≥t 预设3 set the refrigerator to exit the "condensing fan shutdown mode", where the refrigerator exiting the "condensing fan shutdown mode" means that the condensing fan resumes its working state in the normal refrigeration mode of the refrigerator.

[0018] As a further improvement of an embodiment of the present invention, when the difference T 间室 between the temperature of the compartment T 蒸发 and the evaporation temperature T 间室 -T 蒸发 satisfies T 间室 -T 蒸发 <T 预设2 obtain the shutdown time t 停机 of the condensing fan, and judge whether the shutdown time t 停机 satisfies t 停机 ≥t 预设4 , where t 预设4 is the fourth preset time, t 预设4 >t 预设3 ;

[0019] When the shutdown time t 停机 whether it satisfies t 停机 ≥t 预设4, set the refrigerator to exit the "condenser fan shutdown mode".

[0020] As a further improvement of an embodiment of the present invention, t 预设3 is 2 h, and t 预设4 is 3 h.

[0021] As a further improvement of an embodiment of the present invention, T 预设1 ≤2°C, 3°C ≤ T 预设2 ≤10°C.

[0022] As a further improvement of an embodiment of the present invention, the aforementioned condenser fan restores the working state of the refrigerator in the normal refrigeration mode according to the ambient temperature and the target refrigeration temperature T 目标 to control the opening and closing of the condenser fan.

[0023] As a further improvement of an embodiment of the present invention, 2 h ≤ t 预设1 ≤ 3 h.

[0024] Another technical solution adopted by the present invention is:

[0025] A refrigerator, comprising a box body, a door body, a refrigeration system and a collection unit;

[0026] The refrigeration system includes a compressor, a condenser, a throttling component, and an evaporator connected in sequence;

[0027] The box body includes a storage compartment, an evaporator compartment for accommodating the evaporator, and a compressor compartment for placing the compressor and the condenser;

[0028] The door body is used to open or close the storage compartment;

[0029] The compressor compartment is also provided with a condenser fan for dissipating heat from the condenser;

[0030] The collection unit includes a compartment sensor disposed in the storage compartment and a defrost sensor disposed in the evaporator compartment and close to the evaporator;

[0031] The refrigerator further includes a control system electrically connected to the collection unit;

[0032] Wherein, the control system includes a memory and a processor, the memory stores a computer program that can run on the processor, and when the processor executes the computer program, it implements the steps in the refrigerator control method described above.

[0033] As a further improvement of an embodiment of the present invention, after the condenser fan stops working, when the control system obtains the compartment temperature T 间室 reaches the target refrigeration temperature T set by the user 目标 , the control system is based on the ambient temperature and the target refrigeration temperature T目标 to control the opening and closing of the condensation fan.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: The refrigerator control method and refrigerator provided by the present invention do not require any additional components. When the continuous operation time t of the compressor 连续 ≥t 预设1 it is determined that the refrigerator has a refrigeration failure. Then, by obtaining the temperature difference between the compartment temperature T 间室 and the evaporation temperature T 蒸发 it is judged that the control logic of the condensation fan causes the refrigeration failure. Therefore, it enters the "condensation fan shutdown mode", the condensation fan stops working, and the refrigerant in the gaseous state in the condenser increases, so that the gas-liquid two-phase refrigerant entering the capillary increases, improving the vaporization heat absorption capacity of the evaporator, increasing the heat exchange amount of the evaporator, and thus improving the refrigeration efficiency of the refrigerator. The implementation of this technical solution does not require any modification to the original refrigerator structure. Only by obtaining the compartment temperature T 间室 and the evaporation temperature T 蒸发 and using a reasonable control method, the phenomenon of poor refrigeration or non-refrigeration of the refrigerator can be solved. In addition, by means of various method steps to exit the "condensation fan shutdown mode", the working state of the refrigerator in the normal refrigeration mode is restored, and at the same time, it is also a self-check of the previous refrigeration failure judgment, having the advantages of easy implementation of the control method, cost reduction, ensuring refrigeration depth, and improving refrigeration efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The following elaborates on the preferred embodiments of the present invention in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0040] The terms "comprise" and "have" and any variations thereof in the present invention are intended to cover non-exclusive inclusion. The mention of "embodiment" herein means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears at various positions in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0041] Combined with Figure 1 As shown, in this embodiment, the present invention mainly relates to: a refrigerator, comprising a box body 1, a door body 2 for opening or closing the box body 1, a refrigeration system 3 provided in the box body 1, and a collection unit.

[0042] Combined with Figure 2 As shown, the refrigeration system 3 includes a compressor 31, a condenser 32, a throttling component 35, and an evaporator 36 connected in sequence. Preferably, the throttling component 35 is a capillary tube.

[0043] Furthermore, the refrigeration system 3 further includes a return air pipe connected to the outlet end of the evaporator 36.

[0044] Among them, the compressor 31, the condenser 32, the capillary tube, and the evaporator 36 are connected in sequence to form a refrigeration circuit. The refrigerant is compressed by the compressor 31 and then enters the condenser 32. After being condensed into a gas-liquid two-phase refrigerant, it comes out of the condenser 32 and enters the capillary tube for throttling. The temperature and pressure of the refrigerant are reduced to the required evaporation temperature and then enter the evaporator 36 for heat exchange with the heat load of the invention. The refrigerant at the outlet end of the evaporator 36 is in a superheated gas state. At this time, the refrigerant in the superheated gas state enters the return air pipe and finally returns to the compressor 31 to improve the heat exchange efficiency of the evaporator 36, improve the energy efficiency ratio, and improve the refrigeration efficiency.

[0045] Furthermore, the refrigeration system 3 further includes a drying filter 34 connected between the condenser 32 and the capillary tube, and an anti-dew pipe 33 connected between the condenser 32 and the drying filter 34. The anti-dew pipe 33 is arranged at the opening of the box body 1. The compressor 31, the condenser 32, the anti-dew pipe 33, the drying filter 34, the capillary tube, the evaporator 36, and the return air pipe are connected in sequence to form a refrigeration circuit.

[0046] After the refrigerant is compressed, it flows through the pipeline to the condenser 32 and then through the anti-dew pipe 33. The refrigerant heats the opening of the box body 1 in the anti-dew pipe 33. Both the condenser 32 and the anti-dew pipe 33 play a role in condensing the refrigerant. After the refrigerant is cooled, it flows to the drying filter 34. After drying and filtering, the moisture and impurities of the refrigerant are reduced.

[0047] The box body includes a storage compartment, an evaporator bin for accommodating the evaporator 36, and a compressor compartment 11 for placing the compressor 31 and the condenser 32. Among them, the door body 2 is used to open or close the storage compartment.

[0048] The compressor compartment 11 is formed at the bottom of the box body 1. The compressor compartment 11 is also provided with a condensation fan for dissipating heat from the condenser 32. The condensation fan is arranged close to the condenser 32, and the air of the condensation fan forms a heat exchange co-current with the condenser 32, with high heat exchange efficiency.

[0049] The acquisition unit includes a compartment sensor arranged in the storage compartment and a defrost sensor arranged in the evaporator bin and close to the evaporator 36. The compartment sensor is used to obtain the temperature in the compartment, and the defrost sensor is used to obtain the temperature at the evaporator 36 in the evaporator bin. The functions of the compartment sensor and the defrost sensor are conventional technical means in the art and will not be elaborated here.

[0050] Combined Figure 3 As shown, the refrigerator further includes a control system electrically connected to the acquisition unit. Among them, the control system includes a memory and a processor. The memory stores a computer program that can run on the processor. When the processor executes the computer program, the steps in the following refrigerator control method are realized.

[0051] Further, after the condensation fan stops working, when the control system obtains the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 set by the user, the control system controls the opening and closing of the condensation fan according to the ambient temperature and the target refrigeration temperature T 目标 .

[0052] A refrigerator control method includes the following steps:

[0053] Obtain the continuous operation time t 连续 of the compressor of the refrigerator, and judge whether t 连续 satisfies t 连续 ≥t 预设1 , where t 预设1 is the first preset threshold for the continuous operation of the compressor, which is set according to the refrigeration rate of the refrigerator in the normal refrigeration mode;

[0054] When t 连续 satisfies t 连续 ≥t 预设1 , obtain the compartment temperature T 间室 of the storage compartment of the refrigerator and the evaporation temperature T 蒸发 at the evaporator 36 of the refrigerator, and judge the difference T 间室 between the compartment temperature T and the evaporation temperature T 蒸发 , where T 间室 -T 蒸发Whether T is satisfied 间室 -T 蒸发 <T 预设1 , where T 预设1 The refrigerator is in normal refrigeration mode, and the compartment temperature T 间室 and evaporation temperature T 蒸发 The minimum temperature difference threshold that can be achieved; when T 间室 -T 蒸发 Meet T 间室 -T 蒸发 <T 预设1 When the refrigerator is set to enter the "condensing fan stop mode", the refrigerator entering the "condensing fan stop mode" means that the condensing fan of the condenser 32 of the refrigerator stops working.

[0055] Preferably, t 预设1 ≥2h.

[0056] Furthermore, 2 h≤t 预设1 ≤3h, in this embodiment, t 预设1 Set to 2h.

[0057] Preferably, T 预设1 ≤2℃, in this embodiment, T 预设1 Set to 2°C.

[0058] Specifically, if the compressor runs continuously for ≥2 hours, it means that during this period of time, the compartment temperature T 间室 The target cooling temperature T has not yet been reached 目标 , where the target cooling temperature T 目标 It refers to the target refrigeration temperature value set by the user, at which point the refrigerator is judged to have a refrigeration failure.

[0059] And T 间室 -T 蒸发 When the temperature is lower than 2°C, it is determined that the refrigeration temperature of the evaporator bin has not reached the lowest temperature value of the refrigerator in the normal refrigeration mode, the vaporization heat absorption capacity of the evaporator 36 is reduced, and it is inferred that the gas-liquid two-phase refrigerant entering the capillary tube is too little, so it is determined that the control logic of the condensing fan has caused the refrigeration failure, so the "condensing fan shutdown mode" is entered, the condensing fan stops working, and the gaseous refrigerant in the condenser 32 increases, so that the gas-liquid two-phase refrigerant entering the capillary tube increases, the vaporization heat absorption capacity of the evaporator 36 is increased, and the heat exchange capacity of the evaporator 36 is increased, thereby improving the refrigeration efficiency of the refrigerator. The implementation of this technical solution does not require any changes to the original refrigerator structure, and only requires obtaining the compartment temperature T 间室 , evaporation temperature T 蒸发 , with reasonable control methods, the problem of poor refrigeration or no refrigeration in the refrigerator can be solved.

[0060] Further, after the refrigerator enters the "condenser fan shutdown mode", it is determined whether the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 , where the target refrigeration temperature T 目标 refers to the target refrigeration temperature value set by the user to be achieved;

[0061] When the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 , the compressor is set to stop, and the refrigerator is set to exit the "condenser fan shutdown mode", where the refrigerator exiting the "condenser fan shutdown mode" means that the condenser fan resumes its working state in the normal refrigeration mode of the refrigerator.

[0062] Specifically, when the refrigerator enters the "condenser fan shutdown mode", if the compartment temperature T 间室 reaches the target refrigeration temperature T 目标 , it indicates that the aforementioned refrigeration fault of the refrigerator has been alleviated. Therefore, at this time, the condenser fan can resume its working state in the normal refrigeration mode of the refrigerator, and at the same time, it is a self-verification of the previous refrigeration fault judgment, with the advantages of easy implementation of the control method and cost reduction.

[0063] Further, when the compartment temperature T 间室 does not reach the target refrigeration temperature T 目标 , it is determined whether the difference T 间室 between the compartment temperature T and the evaporation temperature T 蒸发 satisfies T 间室 -T 蒸发 ≥T 间室 -T 蒸发 ≥T 预设2 , where T 预设2 >T 预设1 ;

[0064] When the difference T 间室 between the compartment temperature T and the evaporation temperature T 蒸发 satisfies T 间室 -T 蒸发 ≥T 间室 -T 蒸发 ≥T 预设2 , the shutdown time t 停机 of the condenser fan is obtained, and it is determined whether the shutdown time t 停机 satisfies t 停机 ≥t 预设3 , where t 预设3 is the third preset time, which is the first threshold for setting the shutdown time of the condenser fan on the premise of ensuring the refrigeration depth of the refrigerator;

[0065] When the shutdown time t 停机 satisfies t 停机 ≥t 预设3When it is time, set the refrigerator to exit the "condenser fan shutdown mode", where t 停机 Start timing from when the refrigerator enters the "condenser fan shutdown mode". The refrigerator exiting the "condenser fan shutdown mode" means that the condenser fan resumes its working state in the normal refrigeration mode of the refrigerator.

[0066] And when the condenser fan resumes its working state in the normal refrigeration mode of the refrigerator, t 停机 Is reset to zero.

[0067] Preferably, 3°C ≤ T 预设2 ≤ 10°C. In this embodiment, T 预设2 Is set to 5°C.

[0068] Preferably, t 预设3 Is set to the shortest shutdown time of the condenser fan on the premise of ensuring the refrigeration depth of the refrigerator. In this embodiment, t 预设3 Is 2h.

[0069] Specifically, when T 间室 -T 蒸发 ≥ 5°C, at this time, the heat exchange capacity of the evaporator 36 can fully meet the heat exchange requirements of the items in the storage room, indicating that the aforementioned refrigeration fault of the refrigeration system has been alleviated. Therefore, at this time, the condenser fan can resume its working state in the normal refrigeration mode of the refrigerator, which has the advantages of simple and convenient control method, ensuring the refrigeration depth and improving the refrigeration efficiency.

[0070] Furthermore, when the difference T 间室 between the compartment temperature T 蒸发 and the evaporation temperature T 间室 -T 蒸发 meets T 间室 -T 蒸发 < T 预设2 , obtain the shutdown time t 停机 of the condenser fan, and judge whether the shutdown time t 停机 meets t 停机 ≥ t 预设4 , where t 预设4 is the fourth preset time, t 预设4 > t 预设3 ;

[0071] When the shutdown time t 停机 meets t 停机 ≥ t 预设4 , set the refrigerator to exit the "condenser fan shutdown mode".

[0072] Preferably, t 预设4 is set to the longest shutdown time of the condenser fan. In this embodiment, t 预设4 is set to 3h.

[0073] Specifically, when T 间室 -T 蒸发 <5 °C, the downtime t 停机 reaches the longest downtime of the condensing fan. To prevent the temperature in the compressor compartment from becoming too high due to the condensing fan not working for a long time, which may cause damage to other components in the compressor compartment and force the refrigerator to exit the "condensing fan shutdown mode".

[0074] Furthermore, the aforementioned condensing fan resumes the working state of the refrigerator in the normal refrigeration mode according to the ambient temperature and the target refrigeration temperature T 目标 to control the opening and closing of the condensing fan.

[0075] Compared with the prior art, the refrigerator control method and refrigerator provided by the present invention do not require any additional components. When the continuous operation time t 连续 ≥t 预设1 of the compressor, it is determined that the refrigerator has a refrigeration failure. Then, by obtaining the temperature difference between the compartment temperature T 间室 and the evaporation temperature T 蒸发 , it is judged that the control logic of the condensing fan causes the refrigeration failure. Therefore, it enters the "condensing fan shutdown mode", the condensing fan stops working, and the refrigerant in the gaseous state in the condenser 32 increases, so that the gas-liquid two-phase refrigerant entering the capillary tube increases, improving the vaporization heat absorption capacity of the evaporator 36, increasing the heat exchange amount of the evaporator 36, and thus improving the refrigeration efficiency of the refrigerator. The implementation of this technical solution does not require any modification to the original refrigerator structure. Only by obtaining the compartment temperature T 间室 and the evaporation temperature T 蒸发 , with a reasonable control method, the problem of poor refrigeration or non-refrigeration of the refrigerator can be solved. In addition, by means of various method steps to exit the "condensing fan shutdown mode", the working state of the refrigerator in the normal refrigeration mode is restored, which is also a self-verification of the previous refrigeration failure judgment, having the advantages of easy implementation of the control method, cost reduction, ensuring the refrigeration depth, and improving the refrigeration efficiency.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
