Description

Technical Field

[0001] This application relates to the field of refrigerators, and in particular to a refrigerator refrigeration system cleaning device, method, and refrigerator. Background Technology

[0002] Most refrigerators on the market today use a refrigeration system with a compressor, typically located in the lower or top of the refrigerator body. The compressor compartment houses the condenser system components, which usually include the compressor, evaporator, evaporator coils, condenser, fan, and fan bracket.

[0003] The condenser in refrigerators often uses a microchannel condenser with very dense heat dissipation holes. This microchannel condenser is placed at the bottom of the refrigerator, very close to the ground. Since dust, debris, and animal hair easily accumulate on the ground, these substances also tend to accumulate on the microchannel condenser near the ground. When these substances accumulate to a certain level, they will severely affect the heat exchange of the microchannel condenser, impacting the refrigerator's cooling capacity and thus its lifespan. Therefore, how to achieve automatic cleaning of the refrigerator's refrigeration system is a pressing issue that needs to be addressed.

[0053] Most refrigerators on the market today use a refrigeration system with a compressor, typically located in the lower or top of the refrigerator body. The compressor compartment houses the condenser system components, which usually include the compressor, evaporator, evaporator coils, condenser, fan, and fan bracket.

[0054] Previously, wire-tube condensers were commonly used in refrigeration systems. However, due to their large size, wire-tube condensers have led to a shift towards microchannel condensers and vortex condensers. Compared to wire-tube condensers, microchannel and vortex condensers offer advantages such as smaller size, better heat exchange, and reduced refrigerant charge. Because of these advantages, microchannel and vortex condensers have gained popularity in the refrigerator industry, with more and more refrigerator manufacturers adopting them. Microchannel condensers, in particular, are becoming increasingly widely used.

[0055] Because microchannel condenser technology has only been introduced to the refrigerator industry for a relatively short time, it still faces many market challenges. Currently, refrigerators using microchannel condensers typically place the condenser in the compressor compartment at the bottom of the refrigerator. This compartment has ventilation holes that connect to the outside environment for heat exchange. Since the microchannel condenser is placed at the bottom, very close to the ground, dust, debris, pet hair, and other contaminants easily accumulate there. The microchannel condenser's dense ventilation holes further exacerbate this problem, causing dust, hair, and other debris to accumulate on the condenser. Furthermore, in existing refrigerators, the airflow for heat exchange is fixed from one side to the other, making dust accumulation even more pronounced. When these substances accumulate to a certain level, they severely impact the heat exchange of the microchannel condenser, affecting the refrigerator's cooling capacity and ultimately its lifespan.

[0056] Figure 1 This is a schematic diagram of refrigeration system components in the prior art. (Reference) Figure 1 The refrigeration system is equipped with a compressor 10 and a microchannel condenser 20. A fan, specifically a condenser fan 33, is fixedly installed between the compressor 10 and the microchannel condenser 20. In refrigerators using this refrigeration system, the heat exchange air is generally blown from one side of the refrigerator to the other side, usually from the microchannel condenser 20 to the compressor 10. The fixed airflow direction leads to dust accumulation, affecting the heat exchange effect and energy consumption of the refrigerator.

[0057] Therefore, there is an urgent need to develop a refrigeration system with a small condenser that is not prone to dust accumulation, capable of self-cleaning, requiring minimal human intervention, reducing the hassle for customers, and ultimately improving the heat exchange efficiency of the refrigerator, saving energy, and extending the refrigerator's lifespan.

[0058] This embodiment provides a refrigerator refrigeration system cleaning device. Figure 2 This is a schematic diagram of a refrigerator refrigeration system cleaning device provided in an embodiment of this application, for reference. Figure 2 This invention represents a low-cost design upgrade to the existing refrigeration system, enabling automatic cleaning of the refrigerator's refrigeration system, reducing dust accumulation, and improving heat exchange efficiency. The refrigerator refrigeration system includes a compressor compartment housing a compressor and a condenser; the device includes a cleaning component; the cleaning component is located between the compressor and condenser within the compressor compartment; the cleaning component includes a motor, a rotating platform, and a condenser fan; the motor is embedded in the bottom of the compressor compartment; the rotating platform is connected to the motor, and the condenser fan is fixed to the rotating platform; the motor drives the rotating platform to rotate; the rotating platform, in turn, drives the condenser fan to rotate according to the motor's rotation.

[0059] The compressor compartment has a central chamber above it. By adding a motor inside the compressor compartment, the condenser fan is fixed on a rotating platform. The motor rotates and drives the condenser fan to blow air throughout the entire compressor compartment. This ensures that the airflow is not directed in a fixed direction, but rather in all directions within the compressor compartment, reducing the accumulation of dust. By blowing air 360 degrees in every corner of the compressor compartment, dust is less likely to stick inside. Then, through directional backflushing, the dust is blown out of the compressor compartment, thus cleaning the compressor compartment and consequently the refrigerator's refrigeration system. This prevents dust accumulation in the system, improves the refrigerator's lifespan, and increases its heat exchange efficiency.

[0060] For example, the motor can be a stepper motor, or other motors that can receive signals and drive the rotary table to rotate, thereby driving the condenser fan fixedly mounted on the rotary table. Here, a stepper motor is taken as an example. In some embodiments, the motor includes a rotor; the motor is connected to the rotary table through the rotor; the motor is used to control the rotation of the rotor and drive the rotary table to rotate.

[0061] Based on the aforementioned refrigerator refrigeration system cleaning device, this embodiment provides a method for cleaning a refrigerator refrigeration system. Figure 3 This is a flowchart of a refrigerator refrigeration system cleaning method provided in an embodiment of this application. The method is applied to a refrigerator refrigeration system cleaning device according to the first aspect described above, with reference to... Figure 3 The method includes steps S310 to S340.

[0062] In step S310, in response to the cleaning command, the condenser fan is turned on and the motor is turned on to drive the condenser fan fixed on the rotating table to rotate in a preset first direction.

[0063] When cleaning the refrigerator's refrigeration system, specifically the compressor compartment, is required, the condenser fan must first be turned on according to the cleaning command. A preset pulse signal is then sent to the motor so that the motor drives the condenser fan fixed on the rotating table at a constant speed through the rotor.

[0064] At this time, the condenser fan rotates in the preset first direction. The first direction can be either clockwise or counterclockwise. Here, we take clockwise rotation as an example, that is, the forward rotation direction.

[0065] As the rotary table drives the condenser fan to rotate at a constant speed in the first direction, the condenser fan operates. Typically, the condenser fan is responsible for generating airflow around the condenser to accelerate the transfer of heat from the refrigerant to the surrounding environment. This allows the high-temperature, high-pressure gaseous refrigerant to release heat and cool down. Simultaneously, the condenser fan dissipates heat and utilizes the airflow generated during rotation to loosen dust.

[0066] Before responding to a cleaning command, the process includes: acquiring the compressor's operating status; if the compressor's operating status is determined to be in a stopped state, responding to the cleaning command; if the compressor's operating status is determined to be in a running state, acquiring the compressor's operating status again after a preset waiting time, until the operating status is in a stopped state.

[0067] Step S320: If it is determined that the rotation angle of the current condenser fan has reached the preset angle, control the condenser fan to be turned off.

[0068] When the condenser fan rotates 360 degrees in the first direction, that is, after one full rotation, it means that the airflow it generates has loosened the dust in the compressor compartment, so that the loosened dust can be blown out of the compressor compartment in the future.

[0069] In step S330, the control motor drives the condenser fan fixed on the rotating table to rotate in a preset second direction; the preset second direction is opposite to the preset first direction.

[0070] Specifically, when the condenser fan is currently rotating in a first direction and its rotation angle reaches a preset angle, a pulse signal is reapplied to the motor, causing the motor to drive the condenser fan fixed on the rotary table to rotate in a preset second direction. For example, this second direction is a counter-clockwise rotation direction, i.e., a reverse direction.

[0071] Step S340: If it is determined that the current rotation angle of the condenser fan has reached the preset angle, control the condenser fan and motor to be turned off.

[0072] Once the condenser fan has rotated 360 degrees in the second direction (i.e., one full rotation), the airflow it generates will blow the loosened dust out of the compressor compartment. At this point, the cleaning of the compressor compartment is complete. Then, the condenser fan and motor are turned off to avoid additional energy loss.

[0073] By following the steps above, the compressor compartment is rotated 360 degrees in the first and second directions respectively to blow out the dust and achieve a thorough cleaning of the compressor compartment.

[0074] In some embodiments, a first rotary table contact and a second rotary table contact are preset on the side of the rotary table near the motor; a first housing contact corresponding to the first rotary table contact and a second housing contact corresponding to the second rotary table contact are preset on the bottom of the compressor housing near the rotary table; the first rotary table contact and the second rotary table contact are located at both ends of the straight line where the center point of the rotary table is located; the preset angle includes a first preset direction angle;

[0075] Controlling the start of the condenser fan and the motor to drive the condenser fan fixed on the rotary table to rotate in a preset first direction includes: when the condenser fan rotates in the preset first direction until the first rotary table contact corresponds to the second housing contact and the second rotary table contact corresponds to the first housing contact, determining that the current rotation angle of the condenser fan reaches the first preset direction angle; and controlling the motor to shut down.

[0076] Furthermore, after controlling the motor to shut down, the process includes: after a preset first shutdown time, controlling the motor to start, causing the condenser fan to rotate in a preset first direction until the current rotation angle of the condenser fan reaches a preset angle; when the current rotation angle of the condenser fan reaches the preset angle, the first rotary table contact corresponds to the first hopper contact, and the second rotary table contact corresponds to the second hopper contact; and controlling the fan to shut down.

[0077] Figure 4 This is a cross-sectional view of the cleaning component provided in an embodiment of this application, with reference to... Figure 4 In addition to the condenser fan 33, the rotating platform 32, and the stepper motor, the cleaning component 30 also includes a fan bracket 35 for fixing the fan at a certain angle to the rotating platform 32, or fixing the fan vertically to the rotating platform 32. The stepper motor is embedded in the bottom of the compressor compartment, and contacts A and B are provided on the rotating platform 32; contact A is the first rotating platform contact in the aforementioned embodiment, and contact B is the second rotating platform contact in the aforementioned embodiment. On the bottom of the compressor compartment, near the rotating platform 32, there is a first compartment contact A1 corresponding to the first rotating platform contact, and a second compartment contact B1 corresponding to the second rotating platform contact. When the refrigerator refrigeration system is not in a cleaning state, contacts A and A1 are positioned accordingly, and contacts B and B1 are positioned accordingly.

[0078] refer to Figure 1 and Figure 4 When the compressor 10 is stopped, the condenser fan 33 is turned on and the motor 31 is turned on, so that the condenser fan 33 fixed on the rotary table 32 rotates in a preset first direction. For example, the first direction can be set to forward or reverse. Here, the first direction is set to forward as an example.

[0079] In the initial state, the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. When the rotary table 32 drives the condenser fan 33 to rotate in the preset first direction until the positions of contact A and contact B1 correspond, and the positions of contact B and contact A1 correspond, it means that the condenser fan 33 has rotated 180 degrees in the first direction. At this time, the dust on one side within this 180-degree range is loosened. At this time, the motor 31 is controlled to stop for a period of time, that is, the first stop time.

[0080] Subsequently, after the first shutdown time of the control motor 31, the control motor 31 is turned on. At this time, the control table 32 is still needed to drive the condenser fan 33 to rotate in the preset first direction until the initial state is reached, where the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. At this time, the fan is turned off. In the above stage, the dust in the compressor compartment is loosened 360 degrees, which is convenient for blowing the dust out of the compressor compartment later.

[0081] Figure 5 This is a schematic diagram of the cleaning component provided in an embodiment of this application, with reference to... Figure 5 The stepper motor is connected to the rotary table 32 via the rotor 34. The rotary table 32 is fixedly equipped with a fan bracket 35 and a condenser fan 33. The fan bracket 35 is used to fix the condenser fan 33. The A contact and the B contact are specifically set on the bottom surface of the rotary table 32. They can be set as two protrusions, or corresponding sensors can be set at the contact points to determine whether they are in contact with the contacts set on the bottom plate of the compressor compartment, or whether they correspond to the position of the contacts set on the bottom plate of the compressor compartment.

[0082] In some embodiments, after the dust in the compressor compartment is loosened by blowing, the condenser fan is turned on and the motor is turned on to drive the condenser fan fixed on the rotary table to rotate in a preset second direction. This includes: when the condenser fan rotates in the preset second direction until the first rotary table contact corresponds to the second compressor compartment contact and the second rotary table contact corresponds to the first compressor compartment contact, determining that the current rotation angle of the condenser fan has reached the second preset direction angle; and controlling the motor to turn off.

[0083] Furthermore, after the motor is shut down for a preset second shutdown time, the motor is turned on to rotate the condenser fan in a preset second direction until the current rotation angle of the condenser fan reaches the preset angle. When the current rotation angle of the condenser fan reaches the preset angle, the first rotary table contact corresponds to the first hopper contact, and the second rotary table contact corresponds to the second hopper contact. The fan is then shut down.

[0084] After loosening the dust in the compressor compartment from all angles (360 degrees), the loosened dust needs to be blown out of the compressor compartment. This requires controlling the rotary table to drive the condenser fan to rotate in a preset second direction until the positions of contact A and contact B1 correspond, and the positions of contact B and contact A1 correspond. At this point, it means that the condenser fan has rotated 180 degrees in the second direction. This achieves the blowing of dust from one side of the compressor compartment within 180 degrees in the second direction. Afterward, the motor is controlled to stop for a period of time, which is the second shutdown time.

[0085] Subsequently, after the second shutdown time of the controlled motor, the motor is turned on. At this time, it is still necessary to control the rotary table to drive the condenser fan to rotate in the preset second direction until the initial state is reached, where the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. At this time, the fan is turned off. In the above stage, the dust in the compressor compartment is blown out of the compressor compartment from 360 degrees, completing the cleaning of the compressor compartment.

[0086] This embodiment also provides a refrigerator, which includes the refrigerator refrigeration system cleaning device described in the first aspect above.

[0087] The present embodiment will be described and explained below through specific examples.

[0088] Figure 6 This is a flowchart of the refrigeration system cleaning method provided in this specific embodiment, such as... Figure 6 As shown, a stepper motor is added inside the compressor compartment, and the condenser fan is fixed on the rotating table. The rotating table has contacts A and B, and the bottom plate of the compressor compartment has corresponding contacts A1 and B1. The rotating table drives the fan to rotate through the stepper motor. When the refrigerator compartments stop cooling and the compressor stops, the self-cleaning program is activated. At this time, the fan and stepper motor are turned on. The stepper motor rotates slowly, driving the fan to rotate. The fan blows air in different directions into the compressor compartment, so that the dust that has just settled in the corners is loosened.

[0089] Specifically, when cleaning of the compressor compartment is required, it is determined whether the compressor should be stopped; if the compressor continues to operate, wait for t seconds until the compressor stops. If the compressor stops, the condenser fan is turned on, and the motor is started, causing the condenser fan, which is fixed on the rotary table, to rotate in a preset first direction. For example, the first direction can be set to forward or reverse; here, the first direction is set to forward as an example.

[0090] In the initial state, the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. When the rotary table drives the condenser fan to rotate in the preset first direction until the positions of contact A and contact B1 correspond, and the positions of contact B and contact A1 correspond, it means that the condenser fan has rotated 180 degrees in the first direction. At this time, the dust on one side within this 180-degree range is loosened. Then, the motor is controlled to stop for a period of time, that is, the first stop time t2 seconds.

[0091] When the fan rotates in the opposite direction, contact A contacts contact B1, and contact B contacts A1. At this time, the stepper motor stops rotating and pauses for t2 seconds. The dust loosened by the first blow is then blown in the opposite direction to blow it out of the compressor compartment. After blowing, the stepper motor continues to rotate slowly to blow air onto the other side of the compressor compartment to loosen the dust on that side. When contact A contacts A1 and contact B contacts B1, the 360-degree air blowing of the compressor compartment to loosen the dust is completed. The blower is then turned off. Then, the stepper motor quickly reverses and rotates to the opposite position of the fan. The blower is then turned on and blows for t3 seconds to blow the loosened dust out of the compressor compartment. After this is completed, the blower is quickly reset.

[0092] That is, after the first shutdown time of the controlled motor, the motor is turned on. At this time, it is still necessary to control the rotary table to drive the condenser fan to rotate in the preset first direction until the initial state is reached, where the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. At this time, the fan is turned off. In the above stage, the dust in the compressor compartment is loosened 360 degrees.

[0093] Afterwards, the loosened dust needs to be blown out of the compressor compartment. The rotary table needs to be controlled to drive the condenser fan to rotate in the preset second direction until the positions of contact A and contact B1 correspond, and the positions of contact B and contact A1 correspond. At this time, it means that the condenser fan has rotated 180 degrees in the second direction. This achieves the blowing of dust from one side of the compressor compartment within 180 degrees in the second direction. Afterwards, the motor is controlled to stop for a period of time, namely the second stop time t3 seconds.

[0094] Subsequently, after the second shutdown time of the controlled motor, the motor is turned on. At this time, it is still necessary to control the rotary table to drive the condenser fan to rotate in the preset second direction until the initial state is reached, where the positions of contact A and contact A1 correspond, and the positions of contact B and contact B1 correspond. At this time, the fan is turned off. In the above stage, the dust in the compressor compartment is blown out of the compressor compartment from 360 degrees, completing the cleaning of the compressor compartment.

[0095] By using the above method, a stepper motor that can drive the condenser fan to rotate in all directions is installed in the compressor compartment, realizing a low-cost design upgrade of the existing refrigeration system. This enables automatic cleaning of the refrigeration system, reduces dust accumulation, and improves the heat exchange efficiency of the refrigerator.

[0096] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here. For example, first, the rotary table is controlled to drive the condenser fan to rotate in a preset second direction until the rotation angle reaches a preset angle, i.e., 360 degrees in the second direction; then, the rotary table is controlled to drive the condenser fan to rotate in a preset first direction until the rotation angle reaches a preset angle, i.e., 360 degrees in the first direction, thereby cleaning the compressor compartment.

[0097] If the dust remains firmly adhered to the compressor compartment after the stepper motor drives the condenser fan to rotate 360 ​​degrees in the first direction, you can choose to control the stepper motor to drive the condenser fan to rotate 360 ​​degrees in the first direction again until the dust is loosened. Then, control the stepper motor to drive the condenser fan to rotate 360 ​​degrees in the second direction to blow the loosened dust out of the compressor compartment, thus cleaning the refrigerator's refrigeration system.

[0098] By employing the above cleaning method, a multi-layered, 360-degree all-around cleaning and airflow is achieved in the compressor compartment, preventing dust from easily accumulating and adhering in every corner. This automatically cleans the refrigeration system, reduces dust accumulation, improves the refrigerator's heat exchange efficiency, and extends its lifespan.
