Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and more particularly to a refrigerator and a control method. Background Technology

[0002] With the increasing popularity of integrated home decoration, people's requirements for refrigerators are also gradually rising. They not only demand high aesthetic appeal and superior performance, but also that the refrigerator meets the needs of their home décor. Typically, the space around the refrigerator is well-planned, leading to the gradual phasing out of the traditional side-mounted condenser and side-cooling method. This is increasingly being replaced by a bottom-mounted condenser next to the compressor. This type of refrigerator not only possesses the functions of a regular refrigerator but also blends seamlessly with kitchen cabinetry, creating a unified and aesthetically pleasing kitchen. Currently, bottom-cooling methods mostly rely on natural ventilation or a cooling fan installed between the compressor and condenser. However, these methods suffer from slow heat dissipation and poor airflow, affecting cooling efficiency. Summary of the Invention

[0003] This application provides a refrigerator that can use the liquid flow in the cooling pipes of the cooling assembly to cool the compressor, thereby improving the heat dissipation efficiency of the compressor.

[0004] In a first aspect, this application provides a refrigerator, including a cabinet, a compressor compartment, a compressor, a condenser, and a cooling assembly, the cooling assembly being opposite to the compressor, and the cooling assembly including cooling pipes.

[0005] According to the refrigerator of this application, the compressor can be cooled by the liquid flow in the cooling pipes of the cooling assembly, thereby improving the heat dissipation efficiency of the compressor.

[0006] According to the refrigerator of this application, the cooling assembly further includes a first evaporation plate, which is disposed below at least a portion of the structure of the condenser and is in communication with the inlet end of the cooling water.

[0007] According to the refrigerator of this application, the first evaporation plate can collect the condensate dripping from the surface of the condenser and collect the condensate into the first evaporation plate. The collected condensate flows into the cooling pipe to dissipate heat from the compressor, thereby realizing the collection and effective use of condensate, and at the same time realizing a reasonable spatial layout.

[0008] Optionally, the cooling assembly further includes: The first fan is located inside the compressor chamber and is opposite to the first evaporator.

[0009] According to the refrigerator of this application, the first fan can accelerate the evaporation of defrost water in the first evaporation plate, thereby cooling the compressor and creating airflow in the compressor compartment to dissipate heat from the compressor compartment.

[0010] Optionally, the refrigerator also includes: The second evaporator is connected to the outlet end of the cooling pipe. The compressor and the condenser are arranged side by side. The second evaporator is located on the side of the compressor away from the condenser. The cooling pipe is located below the compressor.

[0011] According to the refrigerator of this application, the second evaporator allows the condensate in the first evaporator to flow into the second evaporator through the cooling pipe. The flow of cooling water in the cooling pipe helps to dissipate heat from the compressor. At the same time, the evaporation of defrost water in the first and second evaporators can also accelerate the cooling speed of the compressor and the compressor compartment, thereby further improving the heat dissipation effect of the cooling components on the compressor and the compressor compartment and improving the heat dissipation efficiency.

[0012] Optionally, the cooling assembly further includes: The third fan is located inside the compressor compartment and is opposite to the second evaporator plate.

[0013] According to the refrigerator of this application, the third fan can accelerate the evaporation of defrost water in the second evaporator plate, thereby cooling the compressor and forming airflow in the compressor compartment to dissipate heat from the compressor compartment. Moreover, the third fan can cooperate with the first fan to form an airflow path in the compressor compartment, further improving the heat dissipation effect on the compressor and the compressor compartment.

[0014] Optionally, the height of the first evaporator is higher than or equal to the height of the second evaporator.

[0015] According to the refrigerator of this application, setting the height of the first evaporator plate to be higher than or equal to the height of the second evaporator plate makes it easier for the defrosting water collected in the first evaporator plate to flow into the cooling pipes and eventually flow to the second evaporator plate.

[0016] Optionally, a second fan is provided between the compressor and the condenser, and the second fan is opposite to the compressor.

[0017] According to the refrigerator of this application, a second fan is installed between the compressor and the condenser, so that the airflow blown by the second fan can directly blow on the compressor and drive the airflow around the condenser, thereby cooperating with the cooling components under certain operating conditions to accelerate the heat dissipation speed of the compressor, condenser and compressor compartment, and improve heat dissipation efficiency.

[0018] Optionally, the compressor is provided with a first temperature sensor for detecting the temperature of the compressor, and the compressor compartment is provided with a second temperature sensor for detecting the temperature inside the compressor compartment.

[0019] According to the refrigerator of this application, a first temperature sensor is used to detect the temperature of the compressor, and a second temperature sensor is used to detect the temperature inside the compressor compartment. The start-up and shutdown of the first fan, or the second fan, or the third fan are controlled by the temperature of the compressor and the temperature inside the compressor compartment.

[0020] Secondly, this application proposes a control method for controlling the aforementioned refrigerator, comprising: Check the first, second, and third fans for any malfunctions; Detect the second temperature inside the compressor chamber; When neither the first fan nor the third fan malfunctions and the second temperature is greater than the second preset temperature, the first fan and the third fan are started and their rotation directions are reversed.

[0021] According to the control method of this application, when the second temperature is detected to be greater than the second preset temperature, it indicates that the temperature inside the compressor chamber has reached the set threshold and urgently needs heat dissipation. The first fan and the third fan are then started and their rotation directions are reversed to form an airflow path between them, thereby accelerating the cooling process.

[0022] The control method according to this application also includes: When the first fan malfunctions but the third and second fans do not malfunction, the second and third fans are controlled to start.

[0023] According to the control method of this application, when the first fan fails and neither the third fan nor the second fan fails, the second fan and the third fan are started regardless of whether the second temperature is greater than or less than or equal to the second preset temperature, so that the second fan replaces the first fan to accelerate the heat dissipation speed in the compressor chamber.

[0024] Optionally, the control method further includes: When neither the first fan nor the third fan malfunctions and the second temperature is less than or equal to the second preset temperature, control both the first fan and the third fan to start and make their rotation directions the same.

[0025] According to the control method of this application, when neither the first fan nor the third fan malfunctions, if the detected second temperature is less than or equal to the second preset temperature, it indicates that the temperature inside the compressor chamber has not exceeded the threshold and the highest level of heat dissipation control is not required. In this case, the first fan and the third fan are both started and rotated in the same direction, so that the first fan and the third fan maintain normal heat dissipation operation.

[0026] Optionally, the control method further includes: Detect the compressor's initial temperature; When the second fan is not malfunctioning and the first temperature is greater than the first preset temperature, the second fan is controlled to start.

[0027] According to the control method of this application, the first temperature of the compressor is detected. When the second fan does not malfunction, if the first temperature is detected to be greater than the first preset temperature, it indicates that the temperature of the compressor exceeds the threshold and urgently needs to dissipate heat. The second fan is then controlled to start and blow directly onto the compressor, thereby accelerating the airflow speed around the compressor, thus improving the heat dissipation efficiency of the compressor and accelerating the heat dissipation of the compressor.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] like Figures 2-5As shown, the refrigerator 1 according to the embodiment of this application includes a cabinet 101, a compressor compartment 10 is provided in the cabinet 101, a compressor 11, a condenser 12 and a cooling assembly 14 are provided in the compressor compartment 10, the cooling assembly 14 is opposite to the compressor 11, and the cooling assembly 14 includes a cooling pipe 141.

[0037] Specifically, the cooling pipe 141 is used to supply coolant. By setting the cooling component 14 next to the compressor 11 and opposite to the compressor 11, the coolant flows in the cooling pipe 141 to dissipate heat from the compressor 11, thereby improving the heat dissipation efficiency of the compressor 11.

[0038] The cooling assembly 14 can be located between the compressor 11 and the condenser 12, or above or beside the compressor 11, or below the compressor 11.

[0039] In addition, the cross-sectional shape of the cooling pipe 141 includes, but is not limited to, a circular shape, a rectangular shape, and an elliptical shape.

[0040] Furthermore, the cooling pipe 141 can be configured to extend in a straight line or in a bend. For example, in one specific embodiment, the cooling pipe 141 bends back and forth and is horizontally distributed. As in another specific embodiment, such as... Figure 2 As shown, the cooling pipe 141 includes a plurality of parallel cooling pipes 1411, and the inlet end of each cooling pipe 1411 is connected to the first evaporation plate 142.

[0041] In one specific embodiment, the refrigerator is configured as an embedded refrigerator, and the compressor 11 and condenser 12 in this application are both located inside the cabinet 101 near the bottom.

[0042] According to the refrigerator 1 of the present application embodiment, the compressor 11 can be cooled by the liquid flow in the cooling pipe 141 of the cooling assembly 14, thereby improving the heat dissipation efficiency of the compressor 11.

[0043] like Figure 4 and Figure 5 As shown, in the refrigerator 1 according to an embodiment of this application, the cooling assembly 14 further includes a first evaporation plate 142. The first evaporation plate 142 is disposed below at least a portion of the structure of the condenser 12, and is connected to the inlet end of the cooling water. Thus, the first evaporation plate 142 can collect the condensate dripping from the surface of the condenser 12, and the collected condensate flows into the cooling pipe 141 to dissipate heat from the compressor 11, thereby achieving the collection and effective utilization of condensate, while also achieving a reasonable spatial layout.

[0044] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in some embodiments, the cooling assembly 14 further includes a first fan 144, which is disposed within the compressor compartment 10 and faces the first evaporator plate 142. It is understood that the first fan 144 accelerates the evaporation of defrost water in the first evaporator plate 142, thereby cooling the compressor 11 and simultaneously creating airflow within the compressor compartment 10 to dissipate heat.

[0045] Since the first evaporator 142 is located below at least part of the structure of the condenser 12, in order to ensure the evaporation effect of the first fan 144 on the defrost water in the first evaporator 142, the first fan 144 can be located on the side of the first evaporator, that is, fixed on the wall of the compressor compartment 10, so as to drive the airflow above the first evaporator 142 as much as possible to accelerate the evaporation speed of the defrost water, thereby accelerating the heat dissipation speed in the compressor compartment 10.

[0046] like Figures 4-6 As shown, in some embodiments, the refrigerator 1 further includes a second evaporator 143, which is connected to the outlet end of the cooling pipe 141. The compressor 11 and the condenser 12 are arranged side by side. The second evaporator 143 is located on the side of the compressor 11 away from the condenser 12, and the cooling pipe 141 is located below the compressor 11.

[0047] In more detail, the defrosting water in the first evaporator 142 can enter the cooling pipe 141 and then enter the second evaporator 143 through the outlet end of the cooling pipe 141. That is to say, the second evaporator 143 allows the condensate in the first evaporator 142 to flow into the second evaporator 143 through the cooling pipe 141. The flow of cooling water in the cooling pipe 141 is used to dissipate heat from the compressor 11. At the same time, the evaporation of defrosting water in the first evaporator 142 and the second evaporator 143 can also accelerate the cooling speed of the compressor 11 and the compressor compartment 10, thereby further improving the heat dissipation effect of the cooling component 14 on the compressor 11 and the compressor compartment 10 and improving the heat dissipation efficiency.

[0048] Secondly, by placing the first evaporator 142 and the second evaporator 143 on both sides of the compressor 11, the air around the compressor 11 can be further cooled, thereby improving the heat dissipation effect of the cooling assembly 14 on the compressor 11.

[0049] like Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 6As shown, in some embodiments, the cooling assembly 14 further includes a third fan 145, which is disposed within the compressor compartment 10 and faces the second evaporator plate 143. It is understood that the third fan 145 accelerates the evaporation of defrost water in the second evaporator plate 143, thereby cooling the compressor 11 and creating airflow within the compressor compartment 10 to dissipate heat. Furthermore, the third fan 145 can cooperate with the first fan 144 to form an airflow path within the compressor compartment 10, further enhancing the heat dissipation effect on the compressor 11 and the compressor compartment 10.

[0050] To ensure the evaporation effect of the third fan 145 on the defrost water in the second evaporator 143, the third fan 145 can be located on the side of the second evaporator, that is, fixed on the wall of the compressor compartment 10, so as to drive the airflow above the second evaporator 143 as much as possible to accelerate the evaporation speed of the defrost water, thereby accelerating the heat dissipation speed in the compressor compartment 10.

[0051] In some embodiments, the height of the first evaporator 142 is higher than or equal to the height of the second evaporator 143. That is, in some embodiments, the height of the first evaporator 142 is higher than the height of the second evaporator 143, and in other embodiments, the height of the first evaporator 142 is the same as the height of the second evaporator 143. In a specific embodiment, the height of the first evaporator 142 is set to be higher than the height of the second evaporator 143. This allows the height difference between the first evaporator 142 and the second evaporator 143 to be used to accelerate the flow rate of cooling water in the cooling pipe 141, thereby improving the efficiency of the cooling water in removing heat from the compressor 11 as it passes the bottom of the compressor 11.

[0052] According to the refrigerator 1 of this application embodiment, the height of the first evaporator 142 is set to be higher than or equal to the height of the second evaporator 143, which makes it easier for the defrosting water collected in the first evaporator 142 to flow into the cooling pipe 141 and eventually flow to the second evaporator 143.

[0053] like Figure 4 and Figure 5 As shown, in some embodiments, a second fan 13 is provided between the compressor 11 and the condenser 12, and the second fan 13 is opposite to the compressor 11.

[0054] According to the refrigerator 1 of this application embodiment, a second fan 13 is installed between the compressor 11 and the condenser 12, so that the airflow blown by the second fan 13 can directly blow the compressor 11 and drive the airflow around the condenser 12, thereby cooperating with the cooling component 14 under certain operating conditions to accelerate the heat dissipation speed of the compressor 11, the condenser 12 and the compressor compartment 10, and improve the heat dissipation efficiency.

[0055] In addition, since the second fan 13 is located between the compressor 11 and the condenser 12, the high ambient temperature around it can easily lead to a higher failure rate and a shorter lifespan. By using the first fan 144 and the third fan 145 in conjunction with the corresponding evaporation plates (first evaporation plate 142 and second evaporation plate 143) located at both ends of the compressor compartment 10, when the second fan 13 fails, the first fan 144 and the third fan 145 can form an airflow path to dissipate heat from the compressor compartment 10, thus avoiding problems such as damage to the compressor 11 or food spoilage after the refrigerator 1 is powered off due to the failure of the second fan 13. Furthermore, when the temperature of the compressor compartment 10 exceeds the threshold, the airflow path generated by the first fan 144 and the third fan 145 rotating in opposite directions can be used to accelerate cooling.

[0056] In some embodiments, the compressor 11 is provided with a first temperature sensor for detecting the temperature of the compressor 11, and the compressor chamber 10 is provided with a second temperature sensor for detecting the temperature inside the compressor chamber 10.

[0057] The first temperature sensor can be installed on the outer wall of the compressor 11, and the second temperature sensor can be installed on the wall of the compressor compartment 10. It should be noted that even if the first temperature sensor is installed next to the compressor 11, as long as the first temperature sensor is used to detect the temperature of the compressor 11, the scheme is essentially the same as this scheme and there will be no fundamental difference.

[0058] According to the refrigerator 1 of this application embodiment, the temperature of the compressor 11 is detected by a first temperature sensor and the temperature inside the compressor compartment 10 is detected by a second temperature sensor. The start-up and shutdown of the first fan 144, the second fan 13, or the third fan 145 are controlled by the temperature of the compressor 11 and the temperature inside the compressor compartment 10.

[0059] like Figure 2 As shown, in some embodiments, the cooling pipe 141 includes a plurality of cooling pipes 1411 arranged in parallel, each cooling pipe 1411 being connected to the first evaporator 142 and the second evaporator 143.

[0060] According to the refrigerator 1 of the present application embodiment, the flow path of the coolant in the first evaporator 142 and the second evaporator 143 is shortened, and the cooling effect on the compressor 11 is prevented from weakening due to the coolant carrying away the heat of the compressor 11 when it flows over the bottom of the compressor 11.

[0061] like Figure 5 and Figure 6 As shown, in some embodiments, the first fan 144 and the third fan 145 are respectively located at both ends of the same side of the compressor chamber 10, and the first fan 144 and / or the third fan 145 are inclined upwards.

[0062] According to the refrigerator 1 of the present application embodiment, the first fan 144 and / or the third fan 145 are inclined upwards, which can increase the airflow disturbance area around the compressor 11, the airflow disturbance area around the first evaporator and / or the third evaporator, accelerate the evaporation rate of defrost water in the first evaporator and / or the second evaporator, thereby improving the heat dissipation efficiency in the compressor compartment 10.

[0063] The control method according to the embodiments of this application is used to control the refrigerator 1 described above, including: Step S10: Check whether there are any faults in the first fan 144, the second fan 13 and the third fan 145; Step S20: Detect the second temperature inside the compressor chamber 10; Step S31: When neither the first fan 144 nor the third fan 145 malfunctions and the second temperature is greater than the second preset temperature, control the first fan 144 and the third fan 145 to start and make the rotation directions of the first fan 144 and the third fan 145 opposite.

[0064] In step S10, the main control board of refrigerator 1 detects whether the first fan 144 and the third fan 145 are faulty, so as to determine whether the first fan 144 and the third fan 145 can respond to the corresponding control logic.

[0065] In one specific embodiment, if a fault is detected in the first fan 144, the display panel of the refrigerator 1 is controlled to display code E1; if a fault is detected in the second fan 13, the display panel is controlled to display code E2; if a fault is detected in the third fan 145, the display panel is controlled to display code E3 and the compressor 11 is turned off.

[0066] In step S20, the second temperature inside the compressor chamber 10 can be detected by the second temperature sensor, thereby determining the operating ambient temperature of the compressor 11 inside the compressor chamber 10.

[0067] It should be noted that steps S10 and S20 are not in any particular order and can be performed simultaneously, or steps S10 can be performed first and then steps S20; or steps S20 can be performed first and then steps S10.

[0068] In step S31, if neither the first fan 144 nor the second fan 13 malfunctions, it indicates that the first fan 144 and the third fan 145 can respond to the corresponding control logic. When the detected second temperature is greater than the second preset temperature, it indicates that the temperature inside the compressor chamber 10 has reached the set threshold and urgently needs heat dissipation. The system then controls the first fan 144 and the third fan 145 to start and rotate in opposite directions, creating an airflow path between them to accelerate cooling. Figure 4 The arrows in the diagram indicate the airflow path formed when the first fan 144 and the third fan 145 rotate in opposite directions.

[0069] In one specific embodiment, when the first fan 144 and the third fan 145 rotate in opposite directions, the configuration is such that the first fan 144 rotates in reverse and the third fan 145 rotates in forward.

[0070] According to the control method of this application embodiment, when the second temperature is detected to be greater than the second preset temperature, it indicates that the temperature inside the compressor chamber 10 has reached the set threshold and urgently needs heat dissipation. The first fan 144 and the third fan 145 are controlled to start and the rotation directions of the first fan 144 and the third fan 145 are reversed, so that an air path is formed between the first fan 144 and the third fan 145 to accelerate cooling.

[0071] The following steps may also include: Step S40: Detect the second temperature inside the compressor chamber 10; Step S50: When the second temperature is detected to be less than or equal to the second preset temperature, control... According to the control method of this application, it can also be: Step S10: Check whether the first fan 144 and the third fan 145 are faulty; Step S20: When neither the first fan 144 nor the third fan 145 malfunctions, control the first fan 144 and the third fan 145 to run in the same direction; Step S30: Detect the second temperature inside the compressor chamber 10; Step S40: When the second temperature is detected to be greater than the second preset temperature, control the first fan 144 and the third fan 145 to run in opposite directions.

[0072] The control method according to the embodiments of this application further includes: Step S32: When the first fan 144 fails, but the third fan 145 and the second fan 13 do not fail, control the second fan 13 and the third fan 145 to start.

[0073] In step S32, when the first fan 144 fails and the third fan 145 and the second fan 13 do not fail, the second fan 13 and the third fan 145 are started. The second fan 13 is used to start in place of the first fan 144 to form airflow in the compressor chamber 10, thereby accelerating the flow of air in the compressor chamber 10.

[0074] According to the control method of this application, when the first fan 144 fails and neither the third fan 145 nor the second fan 13 fails, regardless of whether the second temperature is greater than the second preset temperature or less than or equal to the second preset temperature, the second fan 13 and the third fan 145 are controlled to start, so that the second fan 13 runs in place of the first fan 144, thereby accelerating the heat dissipation speed in the compressor chamber 10.

[0075] In some embodiments, the control method further includes: Step S33: When neither the first fan 144 nor the third fan 145 malfunctions and the second temperature is less than or equal to the second preset temperature, control both the first fan 144 and the third fan 145 to start and rotate in the same direction. For example... Figure 5 The arrows in the diagram show the airflow path formed when the first fan 144 and the third fan 145 rotate in the same direction.

[0076] In one specific embodiment, the first fan 144 and the third fan 145 are both configured to rotate in the same direction when they are rotating in the same direction.

[0077] According to the control method of this application embodiment, when neither the first fan 144 nor the third fan 145 malfunctions, if the detected second temperature is less than or equal to the second preset temperature, it indicates that the temperature inside the compressor chamber 10 has not exceeded the threshold and the highest level of heat dissipation control is not required. In this case, the first fan 144 and the third fan 145 are both started and rotated in the same direction, so that the first fan 144 and the third fan 145 maintain normal heat dissipation operation.

[0078] In some embodiments, the control method further includes: Step S11: Detect the first temperature of compressor 11; Step S21: When the second fan 13 is not malfunctioning and the first temperature is greater than the first preset temperature, control the second fan 13 to start.

[0079] In step S11, the first temperature of the compressor 11 can be detected by the first temperature sensor.

[0080] In step S21, when the second fan 13 does not malfunction, it means that the second fan 13 can execute the corresponding control logic. When the first temperature is detected to be greater than the first preset temperature, it means that the temperature of the compressor 11 exceeds the threshold and urgently needs to dissipate heat. The second fan 13 is controlled to start and blow directly on the compressor 11 to accelerate the air flow speed around the compressor 11, thereby improving the heat dissipation efficiency of the compressor 11 and accelerating the heat dissipation of the compressor 11.

[0081] According to the control method of this application embodiment, the first temperature of the compressor 11 is detected. When the second fan 13 does not malfunction, if the first temperature is detected to be greater than the first preset temperature, it indicates that the temperature of the compressor 11 exceeds the threshold and urgently needs to dissipate heat. The second fan 13 is then controlled to start and blow directly onto the compressor 11, thereby accelerating the airflow speed around the compressor 11, thereby improving the heat dissipation efficiency of the compressor 11 and accelerating the heat dissipation of the compressor 11.

[0082] It is understandable that when the second fan 13 fails, the airflow formed by the first fan 144 and the third fan 145 can also dissipate heat from the compressor compartment 10, thus avoiding problems such as damage to the compressor 11 or food spoilage after the refrigerator 1 is powered off due to the failure of the second fan 13.
