Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of refrigerators, and particularly relates to a refrigerator and a control method thereof. BACKGROUND

[0002] With the gradual improvement of people's living quality, the trend of kitchen appliance integration is increasingly obvious, and people's demand for embedded refrigerators is also increasing. However, when embedding the embedded refrigerator into the wall or cabinet, there is usually no reserved space at the bottom and side wall of the refrigerator, which limits the heat dissipation condition. At present, the embedded refrigerator mainly dissipates heat through the condenser arranged in the compressor chamber at the bottom of the refrigerator. The condenser and compressor in the compressor chamber emit a large amount of heat, and due to the small space of the compressor chamber, the air circulation is not smooth, and the heat in the compressor chamber cannot be discharged in time, which seriously affects the refrigeration effect and equipment life of the refrigerator.

[0003] The prior art discloses a refrigerator, the bottom of the refrigerator is provided with a compressor chamber, the side of the refrigerator is provided with an air outlet air duct in communication with the compressor chamber, and a fan is arranged in the air outlet air duct. When the fan is turned on, it drives the compressor chamber to take in air from the air inlet, and the air is discharged through the air outlet air duct. The compressor chamber discharges air through a single air outlet channel, and the air discharge efficiency is low, which affects the heat dissipation efficiency of the compressor chamber. Although additional air outlet air ducts and fans can be added to improve the air discharge and heat dissipation efficiency of the compressor chamber, the fans in each air outlet air duct are likely to interfere with each other when they operate simultaneously, which will affect the air discharge efficiency of each air outlet air duct and reduce the heat dissipation efficiency of the compressor chamber. Therefore, the problem needs to be solved. SUMMARY

[0004] Therefore, the present application provides a refrigerator and a control method thereof, which mainly solves the technical problem of how to improve the heat dissipation efficiency of the compressor chamber.

[0005] In order to solve the above problems, the present application provides a refrigerator, which comprises a refrigerator body, a partition plate, a first fan and a second fan. The bottom of the refrigerator body is provided with a compressor chamber. The partition plate is used to separate the compressor chamber into a first chamber for accommodating a compressor and a second chamber for accommodating a first condenser. The first chamber has a first air inlet, and the second chamber has a second air inlet. The first chamber is communicated with a first air outlet air duct, and the second chamber is communicated with a second air outlet air duct. The first fan is used to drive the air in the first chamber to flow out through the first air outlet air duct, and the second fan is used to drive the air in the second chamber to flow out through the second air outlet air duct.

[0006] In some embodiments, the compressor chamber has an air inlet, and the partition plate separates the air inlet into the first air inlet and the second air inlet.

[0007] The position of the partition is adjustable so that the size of the first air inlet and the second air inlet can be adjusted separately, so that when one of the first air inlet and the second air inlet becomes larger, the other becomes smaller.

[0008] In some embodiments, the refrigerator further includes a drive mechanism having a drive cylinder, which drives the partition to move to adjust the position of the partition.

[0009] In some implementations, the rotational speeds of both the first and second fans can be adjusted independently.

[0010] In some embodiments, the compressor compartment has a base plate, the base plate including a compressor base plate section and an air inlet plate section, the air inlet plate section and the compressor base plate section being arranged sequentially along the width direction of the refrigerator, the compressor being mounted on the compressor base plate section, and the second air inlet being disposed on the air inlet plate section;

[0011] The refrigerator body has a first side plate adjacent to the bottom plate at one end in the length direction. The first side wall of the first compartment is located on the first side plate. The first side wall is provided with a first air vent. The first compartment is connected to the first air outlet duct through the first air vent.

[0012] In the refrigerator body, along its length, the first air vent is opposite to the compressor, and there is a gap between the compressor and the first air vent. The air inlet section has a first region opposite to the gap and a second region opposite to the compressor, and the first air inlet is located in the second region.

[0013] In some embodiments, the refrigerator body has a first side and a second side. A first air outlet duct is disposed on the first side and extends along the height direction of the first side to the top of the refrigerator body for air outlet. A second air outlet duct is disposed on the second side and extends along the height direction of the second side to the top of the refrigerator body for air outlet. The first air outlet duct dissipates heat to the first side through internal airflow, and the second air outlet duct dissipates heat to the second side through internal airflow.

[0014] In some embodiments, the first side has a first side plate, the first side plate forms the first air outlet duct, the first compartment wall is provided with a first air passage that extends into the first air outlet duct, and the first compartment is connected to the first air outlet duct through the first air passage.

[0015] The first fan has a first centrifugal fan and a first hood seat mounted on the first centrifugal fan. The first hood seat is provided with a first A air inlet and a first air outlet. The first centrifugal fan takes in air through the first A air inlet and exits air through the first air outlet. The center line of the first A air inlet is perpendicular to the center line of the first air outlet. The first fan is disposed in the first air outlet duct, and the first A air inlet is opposite to the first air outlet. The first air outlet faces the air outlet of the first air outlet duct.

[0016] In some embodiments, the first side and the second side are opposite sides of the refrigerator body; wherein the first air outlet duct and the second air outlet duct are symmetrically arranged, and the first fan and the second fan are also symmetrically arranged.

[0017] In some embodiments, a second condenser is provided in the first air outlet duct, and a third condenser is provided in the second air outlet duct.

[0018] In some embodiments, the second condenser is a tubular condenser, and a first support seat is provided in the first air outlet duct. The first support seat is provided with a first buckle, which is used to engage with the condenser tube of the second condenser.

[0019] And / or, the third condenser is a tubular condenser, and a second support is provided in the second air outlet duct. The second support is provided with a second buckle, which is used to engage with the condenser tube of the third condenser.

[0020] In some embodiments, the refrigerator further includes a compressor, a throttling device, and an evaporator, wherein the compressor, first condenser, third condenser, second condenser, throttling device, and evaporator are connected end-to-end to form a refrigerant circulation loop.

[0021] In some embodiments, the second compartment is provided with a water tray, the refrigerator body has a defrost water discharge channel for discharging defrost water into the water tray, and the first condenser is disposed in the water tray.

[0022] In some embodiments, the present invention also provides a control method for the above-mentioned refrigerator, the control method comprising: detecting the difference ΔT1 between the temperature T1 at the compressor and the ambient temperature T; if ΔT1 is greater than a first preset temperature, adjusting the first fan to high speed; if ΔT1 is less than or equal to the first preset temperature and greater than or equal to a second preset temperature, adjusting the first fan to medium speed; if ΔT1 is less than the second preset temperature, adjusting the first fan to low speed.

[0023] And / or, when the second compartment is provided with a drip tray, the refrigerator body has a defrost water discharge channel for draining defrost water to the drip tray, and the first condenser is located in the drip tray, the control method includes: detecting the difference ΔT2 between the temperature T2 at the third condenser and the ambient temperature T; if ΔT2 is greater than a first preset temperature, adjusting the second fan to high speed; if ΔT2 is less than or equal to the first preset temperature and greater than or equal to the second preset temperature, adjusting the second fan to medium speed; if ΔT2 is less than the second preset temperature, adjusting the second fan to low speed.

[0024] The refrigerator and its control method provided by the present invention have the following beneficial effects:

[0025] 1. Compared to the existing technology where the compressor compartment exhausts air through a single air outlet duct, the compressor compartment of this invention exhausts air simultaneously through two air outlet ducts, namely the first air outlet duct and the second air outlet duct. Because the compressor compartment exhausts air through a larger number of air outlet ducts, its exhaust and heat dissipation efficiency is improved. Furthermore, this invention divides the compressor compartment into an independent first compartment and an independent second compartment by setting a partition, and places the compressor and the first condenser, which generate significant heat, in separate compartments. The first compartment is connected to the first air outlet duct for independent exhaust, and the second compartment is connected to the second air outlet duct for independent exhaust. This prevents interference between the airflow in each compartment when the first and second fans are running simultaneously, thereby improving the exhaust efficiency of each compartment and enhancing the overall exhaust efficiency of the compressor compartment, thus improving its overall heat dissipation efficiency.

[0026] 2. By adjusting the position of the partition, the size of the first air inlet and the second air inlet can be adjusted separately, which can balance the heat dissipation of the compressor and the first condenser and prevent the temperature of the compressor and the first condenser from being too high, thus affecting the refrigeration effect and equipment life of the refrigerator.

[0027] 3. Since the speeds of both the first and second fans can be adjusted independently, precise temperature control and energy-saving operation can be achieved in both the first and second compartments. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0042] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0044] See also Figures 1-7 As shown, according to an embodiment of the present invention, a refrigerator is provided, comprising a refrigerator body 24, a partition 16, a first fan 6a, and a second fan 6b. A compressor compartment 1 is provided at the bottom of the refrigerator body 24. The partition 16 divides the compressor compartment 1 into a first compartment 101 for accommodating a compressor 11 and a second compartment 102 for accommodating a first condenser 141. The first compartment 101 has a first air inlet 51, and the second compartment 102 has a second air inlet 52. The first compartment 101 is connected to a first air outlet duct 17, and the second compartment 102 is connected to a second air outlet duct 18. The first fan 6a drives the air in the first compartment 101 to flow out through the first air outlet duct 17. The second fan 6b drives the air in the second compartment 102 to flow out through the second air outlet duct 18.

[0045] Compared to the existing technology where the compressor compartment exhausts air through a single air outlet duct, the compressor compartment 1 of this invention exhausts air simultaneously through two air outlet ducts, namely the first air outlet duct 17 and the second air outlet duct 18. Because the compressor compartment 1 exhausts air through a larger number of air outlet ducts, its exhaust and heat dissipation efficiency is improved. Furthermore, because this invention uses a partition 16 to divide the compressor compartment 1 into an independent first compartment 101 and an independent second compartment 102, and separates the compressor 11 (which generates significant heat) and the first condenser... The compressor chamber 141 is installed in different chambers, with the first chamber 101 connected to the first air outlet duct 17 for independent exhaust, and the second chamber 102 connected to the second air outlet duct 18 for independent exhaust. This prevents the air in each chamber from interfering with each other when the first fan 6a and the second fan 6b are running at the same time, thereby improving the exhaust efficiency of the first chamber 101 and the second chamber 102, improving the overall exhaust efficiency of the compressor chamber 1, and thus improving the overall heat dissipation efficiency of the compressor chamber 1.

[0046] In some implementations, such as Figure 6 As shown, the aforementioned compressor chamber 1 has an air inlet 5, and a partition 16 divides the air inlet 5 into the aforementioned first air inlet 51 and the aforementioned second air inlet 52. The position of the partition 16 is adjustable so that the size of the first air inlet 51 and the second air inlet 52 can be adjusted separately, so that when one of the first air inlet 51 and the second air inlet 52 becomes larger, the other becomes smaller.

[0047] In the above example, the compressor 11 and the first condenser 141 are respectively located in different compartments. When the refrigerator operates under different conditions, the temperatures of the compressor 11 and the first condenser 141 are different. Specifically, when the temperature of the compressor 11 is higher than that of the first condenser 141, it is necessary to increase the heat dissipation of the compressor 11 to prevent damage caused by high-temperature operation. To address this, the present invention can adjust the position of the partition 16 to enlarge the first air inlet 51 and reduce the size of the second air inlet 52. This increases the airflow entering the first compartment 101 through the first air inlet 51, thereby increasing heat dissipation for the compressor 11 and cooling it down. Although the second air inlet 52 is smaller, the lower temperature of the first condenser 141 means that the smaller airflow through the second air inlet 52 is still sufficient to meet the heat dissipation requirements of the first condenser 141. When the temperature of the compressor 11 is low while the temperature of the first condenser 141 is high, it is necessary to increase the heat dissipation of the first condenser 141 to prevent damage caused by high-temperature operation. To address this, the present invention adjusts the position of the partition 16 to enlarge the second air inlet 52 and reduce the size of the first air inlet 51. This increases the airflow entering the second compartment 102 through the second air inlet 52, thereby increasing heat dissipation from the first condenser 141 and cooling it down. Although the first air inlet 51 is smaller, the lower temperature of the compressor 11 means that the reduced airflow through the first air inlet 51 is still sufficient to meet the compressor's heat dissipation requirements.

[0048] In summary, by adjusting the position of the partition 16, the present invention can adjust the size of the first air inlet 51 and the second air inlet 52 respectively, thereby balancing the heat dissipation of the compressor 11 and the first condenser 141 and preventing the compressor 11 and the first condenser 141 from overheating and affecting the refrigeration effect and equipment life of the refrigerator.

[0049] In order to adjust the position of the aforementioned partition 16, in some embodiments, the refrigerator may further include a drive mechanism for driving the partition 16 to move, thereby adjusting the position of the partition 16. Preferably, the drive mechanism may have a drive cylinder, which may be a pneumatic cylinder or a hydraulic cylinder, etc. The drive mechanism drives the partition 16 to move via the drive cylinder to adjust the position of the partition 16.

[0050] In some implementations, such as Figure 2As shown, the aforementioned partition 16 can be disposed in the middle of the compressor chamber 1 along its length. The upper end of the partition 16 is slidably sealed to the upper wall of the compressor chamber 1, and the lower end of the partition 16 is slidably sealed to the lower wall of the compressor chamber 1. The aforementioned air inlet 5 extends along the length of the compressor chamber 1, and the partition 16 is used to move along the length of the compressor chamber 1 to adjust the size of the first air inlet 51 and the second air inlet 52.

[0051] In some embodiments, the rotational speeds of both the first fan 6a and the second fan 6b can be independently adjusted. This allows for individual regulation of the exhaust efficiency of the first chamber 101 and the second chamber 102. For example, when the temperature on the compressor 11 is high, the rotational speed of the first fan 6a can be increased to improve the exhaust efficiency of the first chamber 101, thereby cooling the compressor 11. Similarly, when the temperature on the first condenser 141 is high, the rotational speed of the second fan 6b can be increased to improve the exhaust efficiency of the second chamber 102, thereby cooling the first condenser 141.

[0052] In the above example, since the rotational speeds of both the first fan 6a and the second fan 6b can be adjusted independently, precise temperature control and energy-saving operation can be achieved in the first compartment 101 and the second compartment 102.

[0053] In some implementations, such as Figures 6-7 As shown, the aforementioned compressor compartment 1 has a base plate 15, which is fixed to the bottom of the refrigerator body 24. The base plate 15 includes a compressor base plate section 151 and an air inlet plate section 152. The air inlet plate section 152 and the compressor base plate section 151 are arranged sequentially along the width direction of the refrigerator. The aforementioned compressor 11 is mounted on the compressor base plate section 151, for example, fixed to the compressor base plate section 151. The aforementioned second air inlet 52 is provided on the air inlet plate section 152. The refrigerator body 24 has a first side plate 2 adjacent to the base plate 15 at one end in the length direction. The first side wall of the first compartment 101 is located on the first side plate 2, and a first air passage 19 is provided on the first side wall. The first compartment 101 is connected to the first air outlet duct 17 through the first air passage 19.

[0054] Among them, such as Figure 7 As shown, along the length of the refrigerator body 24, the aforementioned first air inlet 19 is opposite to the compressor 11, and there is a gap 25 between the compressor 11 and the first air inlet 19. The air inlet section 152 has a first region 512 opposite to the gap 25 and a second region 511 opposite to the compressor 11. The aforementioned first air inlet 51 is located in the second region 511. Thus, the air flowing into the first compartment 101 from the first air inlet 51 can flow through the compressor 11, and then flow from the first air inlet 19 into the first air outlet duct 17 for discharge. The path is as follows.Figure 7 a2 in the above. If the first area 512 is also provided with an air inlet, the incoming air will flow directly into the first air outlet 19 through the aforementioned interval 25, as shown in the path. Figure 7 In case of error b, the cold air will not flow through the compressor 11 and will not be able to effectively dissipate heat and cool the compressor 11.

[0055] In the example above, the above settings can prevent cold air entering the first compartment 101 from flowing into the first air vent 19 and being exhausted without cooling the compressor 11.

[0056] like Figure 6 As shown, the aforementioned base plate 15 also has a front base plate section 153, which is disposed on the side of the air inlet plate section 152 opposite to the compressor base plate section 151. There is a predetermined interval between the front base plate section 153 and the compressor base plate section 151, and the air inlet plate section 152 is disposed at this predetermined interval. The air inlet plate section 152 can be a dustproof air inlet plate. The aforementioned air inlet 5 is disposed on the air inlet plate section 152. Cold air enters the compressor compartment 1 through the air inlet plate section 152 from the bottom of the refrigerator body 24. Specifically, cold air enters the first compartment 101 through the first air inlet 51 and enters the second compartment 102 through the second air inlet 52. The aforementioned air inlet 5 can have a mesh structure to achieve a dustproof effect.

[0057] In some implementations, such as Figures 1-2 As shown, the refrigerator body 24 has a first side and a second side. The first air outlet duct 17 is disposed on the first side and extends along the height direction of the first side to the top of the refrigerator body 24 for air outlet. Figure 1 As shown, the air outlet 221 of the first air outlet duct is located at the top of the refrigerator body 24. The aforementioned second air outlet duct 18 is located on the second side and extends along the height direction of the second side to the top of the refrigerator body 24 for air outlet. Figure 1 As shown, the air outlet 321 of the second air outlet duct is located on the top of the refrigerator body 24. The first air outlet duct 17 dissipates heat to the first side through internal airflow, and the second air outlet duct 18 dissipates heat to the second side through internal airflow.

[0058] In the above example, the first air outlet duct 17 and the second air outlet flow through different sides of the refrigerator body 24 and both exit from the top of the refrigerator body 24, which can increase the heat dissipation area of ​​the refrigerator and improve the heat dissipation efficiency of the refrigerator.

[0059] In some implementations, such as Figures 1-2As shown, the aforementioned first side has a first side plate 2, and the aforementioned first air outlet duct 17 is formed inside the first side plate 2. The wall of the first compartment 101 is provided with a first air passage 19 that extends into the first air outlet duct 17. The first compartment 101 is connected to the first air outlet duct 17 through the first air passage 19. The first fan 6a has a first centrifugal fan 61 and a first shroud seat 71 covering the first centrifugal fan 61. The first centrifugal fan 61 can be fixed to the first shroud seat 71 by fasteners such as screws. The first shroud seat 71 is provided with through holes 711 for the screws to pass through. The first shroud seat 71 is provided with a first A air inlet 713 and a first air outlet 712. The first centrifugal fan 61 takes in air through the first A air inlet 713 and exits air through the first air outlet 712. The center line of the first A air inlet 713 is perpendicular to the center line of the first air outlet 712. The first fan 6a is installed inside the first air outlet duct 17, and the first fan 6a can be fixed to the first preset slot 223 on the inner wall of the first air outlet duct 17 by the first fan cover seat 71 (e.g., Figure 5 (As shown). The first air inlet 713 is opposite to the first air outlet 19, and the first air outlet 712 faces the air outlet 221 of the first air outlet duct.

[0060] In the above example, since the first compartment 101 is located at the bottom of the refrigerator body 24 and the first air outlet duct 17 is located on the side of the refrigerator body 24, the first compartment 101 and the first air outlet duct 17 together form an L-shaped structure. By designing the first fan 6a as a centrifugal fan, and utilizing the characteristics of centrifugal fans that allow axial air intake and radial air exhaust, the air in the first compartment 101 can be smoothly drawn into the first air outlet duct 17 for discharge, thereby improving the exhaust efficiency of the first compartment 101. In addition, since the first fan 6a is located inside the first air outlet duct 17, it also avoids the first fan 6a being directly exposed to the high-temperature environment of the first compartment 101, which would affect its service life.

[0061] like Figure 5 As shown, there can be more than two first air outlets 712. The farther the first air outlet 712 is from the first centrifugal fan 61, the larger the opening area is, so as to balance the air volume of each first air outlet 712. When the second condenser 142 is provided in the first air outlet duct 17, the second condenser 142 can be cooled evenly.

[0062] In a specific application example, such as Figure 1 As shown, the aforementioned first side and second side are opposite sides of the refrigerator body 24. The first air outlet duct 17 and the second air outlet duct 18 are symmetrically arranged, and the first fan 6a and the second fan 6b are also symmetrically arranged, which helps to improve the overall heat dissipation uniformity of the refrigerator.

[0063] like Figure 1As shown, the aforementioned second side has a second side plate 3, and the aforementioned second air outlet duct 18 is formed inside the second side plate 3. A second air passage 20 is provided on the wall of the second compartment 102, extending into the interior of the second air outlet duct 18. The second compartment 102 communicates with the second air outlet duct 18 through this second air passage 20. The second fan 6b includes a second centrifugal fan 62 and a second hood seat 72 covering the second centrifugal fan 62. The second hood seat 72 has a second A air inlet 723 and a second air outlet 722. The second centrifugal fan 62 takes in air through the second A air inlet 723 and exits through the second air outlet 722. The centerline of the second A air inlet 723 is perpendicular to the centerline of the second air outlet 722. The second fan 6b is located inside the second air outlet duct 18, with the second A air inlet 723 opposite to the second air passage 20, and the second air outlet 722 facing the air outlet 321 of the second air outlet duct.

[0064] like Figure 5 As shown, both the first side plate 2 and the second side plate 3 can be component structures. The first side plate 2 may include a first side plate base 22 and a first cover plate 21, which are fixedly connected and form the aforementioned first air outlet duct 17. Similarly, the second side plate 3 may include a second side plate base 32 and a second cover plate 31, which are fixedly connected and form the aforementioned second air outlet duct 18. Both the first air outlet duct 17 and the second air outlet duct 18 may have baffles 8 on both sides in the width direction to prevent air leakage. Each baffle 8 may have screw fixing holes 81, and both the first side plate base 22 and the second side plate base 32 may have screw holes 224. Screws can pass through the screw fixing holes 81 to fix each baffle 8 to the corresponding screw hole 224 position.

[0065] In some implementations, such as Figures 4-5 As shown, a second condenser 142 may be provided in the first air outlet duct 17, and a third condenser 143 may be provided in the second air outlet duct 18. In this way, the second condenser 142 and the third condenser 143 cooperate with the first condenser 141 to effectively increase the heat dissipation area of ​​the condenser and improve the heat dissipation efficiency of the refrigerator.

[0066] In some implementations, such as Figures 4-5As shown, the aforementioned second condenser 142 can be a tubular condenser. A first support 9a can be provided within the aforementioned first air outlet duct 17. This first support 9a has a first latch 91, which engages with the condenser tube of the second condenser 142 to fix its position. The first support 9a can be fixed at a second pre-set slot 222 within the first air outlet duct 17. There can be two or more first support 9as to improve the fixing effect on the second condenser 142.

[0067] Similarly, such as Figure 5 As shown, the aforementioned third condenser 143 can be a tubular condenser, and a second support 9b can be provided inside the aforementioned second air outlet duct 18. The second support 9b has a second latch for engaging with the condenser tube of the third condenser 143 to fix its position. The second support 9b can be fixed to a pre-reserved slot within the second air outlet duct 18. There can be two or more second support 9b to improve the fixing effect on the third condenser 143.

[0068] In some implementations, such as Figure 8 As shown, the aforementioned refrigerator also includes a compressor 11, a throttling device 40, and an evaporator 50. The compressor 11, the first condenser 141, the third condenser 143, the second condenser 142, the throttling device 40, and the evaporator 50 are connected end to end to form a refrigerant circulation loop.

[0069] like Figure 8 As shown, the aforementioned throttling device 40 can be a throttling valve or a capillary tube, etc. A dryer filter 30 is also provided in the aforementioned refrigerant circulation loop, which is connected in series between the aforementioned second condenser 142 and third condenser 143.

[0070] like Figure 8 As shown, the aforementioned refrigerant circulation loop is also equipped with an anti-condensation pipe 23, which is connected in series between the aforementioned third condenser 143 and the second condenser 142. The aforementioned refrigerator body 24 has a freezer compartment, and the anti-condensation pipe 23 is installed on the freezer compartment to exchange heat with the freezer compartment and prevent condensation from occurring in the freezer compartment.

[0071] In this system, the refrigerant is discharged from the compressor 11 as a high-temperature, high-pressure gas. Upon entering the first condenser 141, the refrigerant is still at a high temperature, and the first condenser 141 undertakes the primary task of heat dissipation. After passing through the first condenser 141, the refrigerant reaches the third condenser 143, where it has been partially cooled and becomes a medium-temperature, high-pressure liquid. From the third condenser 143, it flows to the anti-condensation pipe 23, which cools the refrigerant through heat exchange within the refrigerator body 24. Finally, the refrigerant flows to the second condenser 142, where its temperature has decreased. This system design ensures a relatively uniform heat distribution on the left and right sides of the refrigerator, avoiding the problem of heat concentration on one side.

[0072] In some implementations, such as Figure 3 As shown, the aforementioned second compartment 102 may be equipped with a drip tray 13, and the refrigerator body 24 has a defrost water discharge channel 12 for draining defrost water into the drip tray 13. The aforementioned first condenser 141 is disposed within the drip tray 13.

[0073] In the above example, by placing the first condenser 141 inside the water receiving pan 13, the defrosting water flowing into the water receiving pan 13 can cool and dissipate heat from the first condenser 141, thereby improving the heat dissipation efficiency of the first condenser 141.

[0074] The defrost water discharge channel 12 can be a drain pipe, and the first condenser 141 can be fixed inside the water receiving tray 13, which can be fixed to the compressor base plate section 151. The first condenser 141 can be a microchannel condenser or a vortex condenser.

[0075] like Figure 5 As shown, the aforementioned refrigerator body 24 also has a back panel 4. The aforementioned compressor compartment 1 has a rear cover 10, which can be fixed to the back panel 4 by fasteners such as screws to seal the compressor compartment 1.

[0076] In some implementations, the aforementioned refrigerator may be an embedded refrigerator.

[0077] In some implementations, such as Figure 9As shown, the present invention also provides a control method for the above-mentioned refrigerator. This control method includes: detecting the difference ΔT1 between the temperature T1 at the compressor 11 and the ambient temperature T, where ΔT1 = T1 - T. If ΔT1 is greater than a first preset temperature, it indicates that the temperature at the compressor 11 is high. In this case, the first fan 6a is adjusted to run at a high speed to accelerate the heat dissipation of the compressor 11. If ΔT1 is less than or equal to the first preset temperature and greater than or equal to a second preset temperature, it indicates that the temperature at the compressor 11 is moderate. In this case, the first fan 6a is adjusted to run at a medium speed. If ΔT1 is less than the second preset temperature, it indicates that the temperature at the compressor 11 is low. In this case, the first fan 6a is adjusted to run at a low speed.

[0078] In the above example, due to the design of the system, since the second condenser 142 is the end of the refrigerant flow and has a lower temperature, the main heat in the air duct formed by the first compartment 101 and the first air outlet duct 17 is concentrated at the compressor 11. By detecting the temperature reduction at the compressor 11 and combining it with the ambient temperature, the speed of the first fan 6a can be dynamically adjusted to achieve precise temperature control and energy-saving operation of the compressor 11.

[0079] In some embodiments, when a drip tray 13 is provided in the second compartment 102, and the refrigerator body 24 has a defrost water discharge channel 12 for draining defrost water to the drip tray 13, and the first condenser 141 is located in the drip tray 13, the aforementioned control method includes: detecting the difference ΔT2 between the temperature T2 at the third condenser 143 and the ambient temperature T, where T2 = T2 - T; if ΔT2 is greater than a first preset temperature, it indicates that the temperature at the third condenser 143 is high, and the second fan 6b is adjusted to high speed to accelerate the heat dissipation of the third condenser 143. If ΔT2 is less than or equal to the first preset temperature and greater than or equal to the second preset temperature, it indicates that the temperature at the third condenser 143 is moderate, and the second fan 6b is adjusted to medium speed. If ΔT2 is less than the second preset temperature, it indicates that the temperature at the third condenser 143 is low, and the second fan 6b is adjusted to low speed.

[0080] In the above example, due to the system design, the first condenser 141 is set in the water receiving pan 13, and the frozen defrosting water has already cooled it for the first time. Then, it is cooled a second time by the cold air entering from the bottom front. Therefore, the main heat in the air duct formed by the second compartment 102 and the second air outlet duct 18 is concentrated at the third condenser 143. By detecting the temperature reduction at the third condenser 143 and combining it with the ambient temperature, the speed of the second fan 6b can be dynamically adjusted to achieve precise temperature control and energy-saving operation of the third condenser 143.

[0081] In a specific application example, the aforementioned first preset temperature can be 20℃, and the second preset temperature can be 10℃. The operating speed of the first fan 6a and the second fan 6b at high speed can be 2500 RPM, the operating speed of the first fan 6a and the second fan 6b at medium speed can be 1200 RPM, and the operating speed of the first fan 6a and the second fan 6b at low speed can be 800 RPM.

[0082] It should be noted that: the first temperature sensor can be used to detect the temperature T1 at the compressor 11, the second temperature sensor can be used to detect the temperature T2 at the aforementioned third condenser 143, and the third temperature sensor can be used to detect the ambient temperature T.

[0083] For ease of understanding, the overall structure of the present invention will be described below, and its working principle will be explained.

[0084] In this invention, by using a first condenser 141 located in the second compartment 102 and second condensers 142 and third condensers 143 located on both sides of the refrigerator body 24, the refrigerator has three condenser sections, effectively increasing the heat dissipation area. The second condenser 142 and third condenser 143 are respectively located on both sides of the refrigerator body 24. The aforementioned first compartment 101, in conjunction with the first air outlet duct 17, forms a first heat dissipation air path, and the second compartment 102, in conjunction with the second air outlet duct 18, forms a second heat dissipation air path. The compressor compartment 1, in conjunction with the first air outlet duct 17 and the second air outlet duct 18, forms a heat dissipation path where air enters from the bottom, cools in the compressor compartment 1, then cools on the sides, and exits from the top, effectively improving the refrigerator's heat dissipation efficiency.

[0085] like Figure 1As shown, cold air enters the compressor compartment 1 through the air inlet 5 on the air inlet section 152 at the bottom of the refrigerator body 24. The partition 16 divides the cold air into two parts. One part enters the first compartment 101 to cool the compressor 11. Then, under the action of the first fan 6a, the cold air enters the first air outlet duct 17 inside the first side panel 2 through the first air vent 19 on the side. The first air outlet duct 17 is formed by the first hood seat 71, the first side panel base 22, the first cover plate 21, and the baffle plate 8. The cold air flows upward through the first air outlet 712 on the first hood seat 71 under the action of the first fan 6a, cooling the second condenser 142, and then is discharged from the top of the first side panel 2. Another portion of the cold air enters the second chamber 102 to dissipate heat from the first condenser 141. Then, under the action of the second fan 6b, the air enters the second air outlet duct 18 through the second air vent 20 on the side. It forms a sealed second air outlet duct 18 through the second hood seat 72, the second side plate base 32, the second cover plate 31 and the baffle plate 8. Under the action of the second fan 6b, the air flows upward from the second air outlet 722 set on the second hood seat 72 to cool the third condenser 143, and then is discharged from the top of the second side plate 3.

[0086] The present invention also uses temperature sensors located at the compressor 11 and the third condenser 143 to dynamically adjust the speed of the first fan 6a and the second fan 6b in combination with the ambient temperature, thereby achieving precise temperature control and energy-saving operation.

[0087] This invention features a multi-stage cooling and heat dissipation system for an embedded refrigerator. This system includes a first condenser 141 within the compressor compartment 1, and second condensers 142 and third condensers 143 on either side of the refrigerator. The refrigerant is designed to travel from the compressor 11 to the first condenser 141, then to the third condenser 143 on the right, then to the second condenser 142 on the left, and finally back to the compressor 11. This multi-stage cooling path achieves bottom air intake, compressor compartment 1 cooling, side condenser heat dissipation, and top air exhaust, forming a highly efficient and stable cooling system and improving overall heat dissipation efficiency. To create a side heat dissipation path, a first fan 6a and a second fan 6b are positioned on either side of the compressor compartment 1. These fans recycle air from the compressor compartment 1 and allow it to enter the side condensers for cooling. This improves air utilization while preventing the first and second fans 6a and 6b from being directly exposed to high temperatures, thus extending their lifespan. In addition, the control method designed in this invention analyzes the location of heat accumulation in the system and sets a temperature sensor at the corresponding location. By comparing the temperature at the heat accumulation location with the ambient temperature, the rotation speed of the first fan 6a and the second fan 6b is dynamically controlled. This achieves good heat dissipation while reducing energy consumption, improving the overall stability and energy-saving performance of the refrigerator, and enhancing the user experience.
