Description

Technical Field

[0001] This invention belongs to the field of refrigerator technology, specifically relating to a refrigerator heat dissipation structure, a refrigerator, and a control method. Background Technology

[0002] Built-in refrigerators have become increasingly popular with consumers in recent years due to their space-saving, aesthetically pleasing, and practical features.

[0003] A refrigerator is disclosed in the prior art, including a compressor compartment and a fan. The compressor compartment contains a compressor, a condenser, and a drip tray. The condenser is located in the drip tray so that the water in the drip tray can be used to dissipate heat and cool the condenser. The compressor compartment has an air inlet and is connected to a heat dissipation duct. When the fan is running, it drives the airflow in the compressor compartment, so that the compressor compartment draws in air through the air inlet and exhausts air through the heat dissipation duct to accelerate the heat dissipation of the compressor compartment.

[0004] When the refrigerator is working, the condenser heats the water in the drip tray into steam. When the fan is turned on, the steam flows into the compressor compartment and is then discharged through the cooling duct. However, as the steam flows through the compressor compartment, it passes over the electronic components and can corrode them, affecting their lifespan. Therefore, this problem needs to be addressed. Summary of the Invention

[0005] Therefore, the present invention provides a refrigerator heat dissipation structure, a refrigerator, and a control method. The main technical problem to be solved is: how to reduce the corrosion of electronic components in the compressor compartment by water vapor in the drip tray.

[0006] To solve the above problems, the present invention provides a refrigerator heat dissipation structure for heat dissipation of the refrigerator. The refrigerator has a compressor compartment for installing a compressor. The compressor compartment is also provided with a water collection tray and a condenser. The condenser is located in the water collection tray.

[0007] The refrigerator heat dissipation structure includes a water collection tray cover, a first air outlet duct, and a first fan. The water collection tray cover is used to fasten to the opening of the water collection tray or to house the water collection tray cover inside, so that the interior of the water collection tray is in communication with the interior of the water collection tray cover.

[0009] In some embodiments, the refrigerator heat dissipation structure further includes a second air outlet duct and a second fan, wherein the second air outlet duct is used to communicate with the space inside the compressor compartment outside the water receiving tray cover.

[0010] The space inside the compressor compartment outside the water receiving tray cover is designated as the first chamber. The water receiving tray cover is used to separate the compressor within the first chamber. The first chamber has a second air inlet. The second fan is used to drive the airflow so that the first chamber receives air through the second air inlet and exhausts air through the second air outlet duct.

[0011] In some implementations, the first air outlet duct and the second air outlet duct are capable of heat exchange.

[0012] In some embodiments, the refrigerator heat dissipation structure further includes a heat exchanger having a first heat exchange channel and a second heat exchange channel that can exchange heat with each other, the first heat exchange channel being connected in series with the first air outlet duct, and the second heat exchange channel being connected in series with the second air outlet duct.

[0013] In some embodiments, the second air outlet duct has a heat exchange duct section, which is disposed on the freezer compartment of the refrigerator to exchange heat with the freezer compartment; wherein, there are two or more heat exchange duct sections, which are arranged in parallel.

[0014] In some embodiments, when there are two heat exchange duct sections, the two heat exchange duct sections are a first heat exchange duct section and a second heat exchange duct section, and the second outlet duct has a connecting duct section located upstream of both the first heat exchange duct section and the second heat exchange duct section. The connecting duct section has an air outlet, and a diverting block is provided at the air outlet. The diverting block divides the air outlet into a first air outlet and a second air outlet. The connecting duct section is connected to the air inlet of the first heat exchange duct section through the first air outlet, and is connected to the air inlet of the second heat exchange duct section through the second air outlet.

[0015] In some embodiments, the air outlet has opposing first and second sidewalls, the diverting block has opposing first and second guide plates, the diverting block is disposed in the middle of the air outlet, and the first guide plate is opposite to the first sidewall to form the first air vent between them; and the second guide plate is opposite to the second sidewall to form the second air vent between them.

[0016] Wherein, the air outlet's air outlet direction is different from the air inlet direction of the first heat exchange duct section, and the first guide plate is arc-shaped to guide the air from the air outlet into the first heat exchange duct section through the first air inlet; and / or, the air outlet's air outlet direction is different from the air inlet direction of the second heat exchange duct section, and the second guide plate is arc-shaped to guide the air from the air outlet into the second heat exchange duct section through the second air inlet.

[0017] In some embodiments, each of the heat exchange duct sections is formed by a recessed first duct cover plate covering the first support beam of the freezer chamber.

[0018] In some embodiments, the first air outlet duct and the second air outlet duct both exhaust air through the same exhaust port, the exhaust port is located on the front side of the refrigerator, and a third fan is provided at the exhaust port.

[0019] In some embodiments, the air inlet of the second air outlet duct is connected to the air outlet of the first chamber, so that the second air outlet duct communicates with the first chamber; wherein, the second fan is disposed at the air inlet of the second air outlet duct, and the air inlet of the second air outlet duct gradually narrows inward along the air outlet direction.

[0020] In some embodiments, the air inlet of the first air outlet duct is connected to the air outlet of the water receiving tray cover, so that the first air outlet duct is connected to the water receiving tray cover; wherein, the first fan is disposed at the air inlet of the first air outlet duct, and the air inlet of the first air outlet duct gradually narrows inward along the air outlet direction.

[0021] In some embodiments, the first air outlet duct has another heat exchange duct section, which is disposed on the freezer compartment of the refrigerator to exchange heat with the freezer compartment; wherein, the other heat exchange duct section is formed by a concave second duct cover plate covering the second support beam of the freezer compartment.

[0022] The present invention also provides a refrigerator, which includes the refrigerator heat dissipation structure described in any one of the above-mentioned methods.

[0023] The present invention also provides a control method for the refrigerator described above. When the refrigerator's heat dissipation structure further includes a second air outlet duct and a second fan, and the second air outlet duct is used to communicate with the space inside the compressor compartment outside the water collection tray cover; the space inside the compressor compartment outside the water collection tray cover is taken as a first chamber, the water collection tray cover is used to separate the compressor within the first chamber, and the first chamber has a second air inlet; the second fan is used to drive airflow, so that the first chamber receives air through the second air inlet and exhausts air through the second air outlet duct; and both the first air outlet duct and the second air outlet duct exhaust air through the same exhaust outlet, and a third fan is provided at the exhaust outlet; and the refrigerator also has an anti-condensation heater for heating the freezer compartment, the control method includes:

[0024] When the compressor starts running, it controls the first fan, the second fan, and the third fan to start running; when the compressor stops running, it controls the first fan, the second fan, and the third fan to each run for a preset time before stopping; when the first fan, the second fan, and the third fan all stop, it controls the anti-condensation heater to start.

[0025] The refrigerator heat dissipation structure, refrigerator, and control method provided by this invention have the following beneficial effects:

[0026] 1. This invention adds a water collection tray cover inside the press chamber, which is fastened to the opening of the water collection tray or placed inside the water collection tray cover, thus connecting the interior of the water collection tray with the interior of the water collection tray cover. Moisture in the water collection tray flows into the water collection tray cover under the drive of the first fan and is discharged separately through the first air outlet duct. This reduces the corrosion of electronic components inside the press chamber by moisture in the water collection tray, thereby improving the service life of the electronic components inside the press chamber.

[0027] 2. The second air outlet duct and the second fan work together to dissipate heat from the compressor compartment, quickly expelling heat from the compressor compartment and preventing overheating of the compressor compartment, thereby improving the refrigerator's cooling efficiency.

[0028] 3. The first and second air outlet ducts exchange heat, allowing the compressor's heat to heat the moisture in the first air outlet duct. This prevents the moisture in the first air outlet duct from condensing and accumulating in the duct or drip tray, which would create a damp environment inside the refrigerator, breed mold, and affect the refrigerator's lifespan and cooling performance.

[0029] 4. The contact area between each heat exchange air duct section and the freezer chamber in this invention is relatively large. Compared with the line contact of traditional freezer anti-condensation pipes, the surface contact of the air duct can transfer heat more evenly, thereby better suppressing the formation of condensation.

[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 Figure 1-7 As shown, according to an embodiment of the present invention, a refrigerator heat dissipation structure is provided for heat dissipation of a refrigerator 1. The refrigerator 1 has a compressor compartment 5, which houses a compressor 51, a drip tray 59, and a condenser 56. The condenser 56 is located within the drip tray 59. The refrigerator heat dissipation structure includes a drip tray cover 511, a first air outlet duct 54, and a first fan 55. The drip tray cover 511 is used to fasten to the opening of the drip tray 59 or to cover the drip tray 59 internally, so that the interior of the drip tray 59 communicates with the interior of the drip tray cover 511. The drip tray cover 511 also covers the condenser 56 internally. The drip tray cover 511 has a first air inlet 510 and communicates with the first air outlet duct 54. The first fan 55 drives airflow, allowing air to enter the drip tray cover 511 through the first air inlet 510 and exit through the first air outlet duct 54.

[0045] In the above example, the present invention adds a water receiving tray cover 511 inside the press chamber 5, which is fastened to the opening of the water receiving tray 59, or covers the water receiving tray 59 inside, so that the interior of the water receiving tray 59 is connected to the interior of the water receiving tray cover 511. Water vapor in the water receiving tray 59 flows into the water receiving tray cover 511 driven by the first fan 55, and is discharged separately through the first air outlet duct 54. This reduces the corrosion of electronic components inside the press chamber 5 by water vapor in the water receiving tray 59, and improves the service life of the electronic components inside the press chamber 5.

[0046] In addition, since the first air outlet duct 54 can promptly discharge the water vapor evaporated from the water tray 59, it can reduce the humid environment on the side of the refrigerator 1, such as the back, and prevent mold growth from affecting the service life and cooling performance of the refrigerator 1.

[0047] It should be noted that: Refrigerator 1 has a defrost water drain pipe 57, which passes through the drip tray cover 511 and connects to the inside of the drip tray 59 to drain the defrost water inside the refrigerator 1 into the drip tray 59. The defrost water flowing into the drip tray 59 can cool the condenser 56. The defrost water drain pipe 57 is located above the drip tray 59 so that the defrost water can flow into the drip tray 59 under the influence of gravity. The aforementioned condenser 56 can be a finned condenser, with its bottom located inside the drip tray 59 but not in contact with it.

[0048] The aforementioned drip tray cover 511 has an opening at one end. In one example, the drip tray cover 511 is used to fasten to the opening of the aforementioned drip tray 59 through the opening. In another example, the drip tray cover 511 is used to fasten to the bottom plate 58 of the compressor chamber 5 through the opening, so as to cover the drip tray 59 inside. The drip tray cover 511 has a lid-like structure and can be fastened to the opening of the drip tray 59 or to the bottom plate 58 of the compressor chamber 5. The fitting of the drip tray cover 511 with the drip tray 59 or the bottom plate 58 of the compressor chamber 5 forms a ventilated space on the side near the defrost water drain pipe 57 and the part fitted with the first air outlet duct 54, while the remaining sides are enclosed.

[0049] In some implementations, such as Figure 1 As shown, the aforementioned refrigerator heat dissipation structure also includes a second air outlet duct 52 and a second fan 53. The second air outlet duct 52 is used to communicate with the space inside the compressor compartment 5 outside the drip tray cover 511. The space inside the compressor compartment 5 outside the drip tray cover 511 is called the first chamber. The drip tray cover 511 is used to separate the aforementioned compressor 51 into the first chamber. The first chamber has a second air inlet 41. The second fan 53 is used to drive airflow, so that the first chamber receives air through the second air inlet 41 and exhausts air through the second air outlet duct 52.

[0050] In the above example, the second air outlet duct 52 and the second fan 53 work together to dissipate heat from the compressor chamber 5, so as to quickly expel the heat inside the compressor chamber 5, avoid overheating of the compressor chamber 5, and improve the cooling efficiency of the refrigerator 1.

[0051] In some embodiments, the aforementioned first air outlet duct 54 and second air outlet duct 52 are capable of heat exchange.

[0052] In this example, the heat emitted by the compressor 51 is higher than that emitted by the condenser 56. Through heat exchange between the first air outlet duct 54 and the second air outlet duct 52, the second air outlet duct 52 can utilize the heat from the compressor 51 to heat the water vapor in the first air outlet duct 54. This prevents the water vapor in the first air outlet duct 54 from condensing into water and accumulating in the duct or drip tray 59, which would cause the internal environment of the refrigerator 1 to be humid and breed mold, affecting the service life and cooling performance of the refrigerator 1.

[0053] In order to enable heat exchange between the aforementioned first air outlet duct 54 and second air outlet duct 52, in some embodiments, such as Figure 1 As shown, the aforementioned refrigerator heat dissipation structure also includes a heat exchanger 711. The heat exchanger 711 has a first heat exchange channel 71 and a second heat exchange channel 72 that can exchange heat with each other. The first heat exchange channel 71 is connected in series with the first air outlet duct 54, and the second heat exchange channel 72 is connected in series with the second air outlet duct 52.

[0054] Both the first heat exchange channel 71 and the second heat exchange channel 72 described above can be heat pipes made of thermally conductive materials such as metal. The first heat exchange channel 71 and the second heat exchange channel 72 are arranged side by side and in contact, and the first heat exchange channel 71 and the second heat exchange channel 72 exchange heat through the contacting duct walls. The first heat exchange channel 71 can be located above the second heat exchange channel 72.

[0055] In some implementations, such as Figure 1 As shown, the aforementioned second air outlet duct 52 may have a heat exchange duct section 6, which is installed on the freezer compartment 3 of the refrigerator 1 to exchange heat with the freezer compartment 3. The heat exchange duct section 6 can utilize the heat from the compressor 51 to heat the freezer compartment 3, thereby preventing condensation from occurring in the freezer compartment 3.

[0056] In some embodiments, the aforementioned heat exchange duct sections 6 can be two or more, and arranged in parallel. By providing a larger number of heat exchange duct sections 6, the heat exchange area between the heat exchange duct sections 6 and the freezer chamber 3 can be increased, further preventing condensation in the freezer chamber 3. Furthermore, the parallel arrangement of the heat exchange duct sections 6 can increase the air outlet area and improve airflow, thus also improving heat exchange and further preventing condensation in the freezer chamber 3.

[0057] In a specific application example, such as Figure 1As shown, when there are two heat exchange duct sections 6, these two heat exchange duct sections 6 are the first heat exchange duct section 6a and the second heat exchange duct section 6b, respectively. The second outlet duct 52 also has a connecting duct section located upstream of both the first heat exchange duct section 6a and the second heat exchange duct section 6b. This connecting duct section can be the aforementioned second heat exchange channel 72. The connecting duct section has an outlet 70, and a diverter block 66 is provided at the outlet 70, which divides the outlet 70 into a first outlet 701 and a second outlet 702. The connecting duct section is connected to the inlet of the first heat exchange duct section 6a through the first outlet 701, and the connecting duct section is connected to the inlet of the second heat exchange duct section 6b through the second outlet 702.

[0058] In the example above, by setting the diversion block 66, the air outlet 70 of the connecting air duct section is divided into two air outlets that respectively supply air to the first heat exchange air duct section 6a and the second heat exchange air duct section 6b. This can achieve parallel connection of the air inlets of the first heat exchange air duct section 6a and the second heat exchange air duct section 6b, and make the air intake of the first heat exchange air duct section 6a and the second heat exchange air duct section 6b more orderly, thereby improving the air intake efficiency of both.

[0059] In some implementations, such as Figure 2 As shown, the aforementioned air outlet 70 has opposing first sidewalls 7a and second sidewalls 7b. The aforementioned diverter block 66 has opposing first guide plates 661 and second guide plates 662. The diverter block 66 is disposed in the middle of the air outlet 70, and the first guide plate 661 is opposite to the first sidewall 7a to form the aforementioned first air vent 701 between the first guide plate 661 and the first sidewall 7a. The second guide plate 662 is opposite to the second sidewall 7b to form the aforementioned second air vent 702 between the second guide plate 662 and the second sidewall 7b.

[0060] In this configuration, the air outlet 70 has an air outlet direction different from the air inlet direction of the first heat exchange duct section 6a. The first guide plate 661 is arc-shaped to guide the air from the air outlet 70 into the first heat exchange duct section 6a via the first air inlet 701. Alternatively, the air outlet 70 has an air outlet direction different from the air inlet direction of the second heat exchange duct section 6b. The second guide plate 662 is arc-shaped to guide the air from the air outlet 70 into the second heat exchange duct section 6b via the second air inlet 702.

[0061] In the above example, when the air outlet direction of the connecting air duct section is different from the air inlet direction of the first heat exchange air duct section 6a and the second heat exchange air duct section 6b, designing the first guide plate 661 and the second guide plate 662 as arc shapes is beneficial for guiding the air and reducing the resistance of the air during the turning process.

[0062] In some implementations, such as Figure 1As shown, each of the aforementioned heat exchange duct sections 6 can be formed by the concave first duct cover plate 7 covering the first support beam of the freezer chamber 3. This can increase the contact area between the heat exchange duct section 6 and the freezer chamber 3. Compared with the line contact of the traditional freezer anti-condensation pipe, the surface contact of the heat exchange duct section 6 can transfer heat more evenly, thereby better suppressing the formation of condensation on the freezer chamber 3.

[0063] The first air duct cover 7 can be fixed to the first support beam by adhesive bonding. In some embodiments, such as... Figure 6 As shown, the aforementioned first support beam may include a middle beam 31, a first vertical beam 34, a second vertical beam 35, and a lower front beam 33. The first vertical beam 34 connects one end of both the middle beam 31 and the lower front beam 33, and the second vertical beam 35 connects the other end of both the middle beam 31 and the lower front beam 33. The aforementioned first heat exchange duct section 6a has a first section 65, a second section 64, and a third section 61 connected sequentially along the air outlet direction. The duct cover plate of the first section 65 covers the lower front beam 33, and the two are bonded together; the duct cover plate of the second section 64 covers the first vertical beam 34, and the two are bonded together; the duct cover plate of the third section 61 covers the middle beam 31, and the two are bonded together. The aforementioned first heat exchange duct section 6a and second heat exchange duct section 6b are symmetrically arranged.

[0064] During production, each heat exchange duct section 6 is subjected to expansion and compression from the insulation material of refrigerator 1, resulting in a good duct sealing effect. The turning points of each heat exchange duct section 6 are transitioned by an arc, and the ratio of the arc radius r to the width d of the heat exchange duct section 6, r / d, is 1.5 to 2. Within this range, the airflow turning resistance is minimized, which can reduce airflow resistance.

[0065] In some implementations, such as Figure 1 and Figure 6 As shown, the aforementioned first air outlet duct 54 and second air outlet duct 52 can both exhaust air through the same exhaust port 310, thus making the overall structure more compact. A third fan 62 can be installed at the exhaust port 310 to accelerate exhaust and improve heat dissipation efficiency. The third fan 62 can be fixed inside the exhaust port 310. When the third fan 62 is activated, it can utilize the siphon principle to exhaust heat and moisture from the exhaust port 310 through both the first and second air outlet ducts 54.

[0066] The aforementioned exhaust vent 310 can be located on the front side of the refrigerator 1 to make the exhaust space more spacious, improve heat dissipation and dehumidification, reduce the humid environment at the back of the refrigerator 1, prevent mold growth, and effectively solve the problem of heat and moisture accumulation in the compressor compartment 5 of the embedded refrigerator 1, which is difficult to exhaust.

[0067] like Figure 6As shown, the exhaust vent 310 can be located in the middle of the central beam 31 of the refrigerator 1. A cover plate 311 can be provided at the exhaust vent 310, and the cover plate 311 can be mesh-shaped.

[0068] In some implementations, such as Figure 1 As shown, the air inlet 521 of the aforementioned second air outlet duct is connected to the air outlet of the first chamber, so that the second air outlet duct 52 is connected to the first chamber. The aforementioned second fan 53 is located at the air inlet 521 of the second air outlet duct, and the air inlet 521 of the second air outlet duct gradually narrows inward along the air outlet direction.

[0069] In the example above, the structure of the air inlet 521 of the second air outlet duct gradually shrinking inward along the air outlet direction has a wind-gathering effect, which can increase the wind speed and facilitate rapid air outlet heat dissipation.

[0070] The air inlet 521 of the aforementioned second air outlet duct can be opposite to the compressor 51, which facilitates the rapid extraction of heat dissipated by the compressor 51. In a specific application example, such as Figure 1 As shown, the air inlet 521 of the second air outlet duct can be located behind the compressor 51. The end of the air inlet 521 of the second air outlet duct is mounted on the lower base plate 58 of the compressor chamber 5, and the starting position of the end of the air inlet 521 of the second air outlet duct is flush with the vertical direction of the lower base plate 58. The aforementioned first fan 55 is mounted on the end face of the air inlet 521 of the second air outlet duct, and the first fan 55 can abut against the end face of the air inlet 521 of the second air outlet duct.

[0071] In some implementations, such as Figure 1 As shown, the air inlet 541 of the aforementioned first air outlet duct is connected to the air outlet of the water receiving tray cover 511, so that the first air outlet duct 54 is connected to the water receiving tray cover 511. The aforementioned first fan 55 is located at the air inlet 541 of the first air outlet duct, and the air inlet 541 of the first air outlet duct gradually narrows inward along the air outlet direction.

[0072] In the example above, the structure of the air inlet 541 of the first air outlet duct gradually shrinking inward along the air outlet direction has a wind-gathering effect, which can increase the wind speed and facilitate rapid air outlet heat dissipation.

[0073] In a specific application example, the air inlet 541 of the aforementioned first air outlet duct can be mounted on the lower base plate 58 of the compressor chamber 5, and the end face of the air inlet 541 of the first air outlet duct, i.e., the starting position, is flush with the vertical direction of the lower base plate 58. The second fan 53 is mounted at the starting position of the air inlet 541 of the first air outlet duct, and the second fan 53 can abut against the end face of the air inlet 541 of the first air outlet duct. The second fan 53 is located above the water receiving tray 59.

[0074] In some implementations, such as Figure 1 As shown, the aforementioned first air outlet duct 54 may have another heat exchange duct section 63, which is installed on the freezer compartment 3 of the refrigerator 1 to exchange heat with the freezer compartment 3. This other heat exchange duct section 63 can utilize the heat from the condenser 56 to heat the freezer compartment 3, thereby preventing condensation from occurring in the freezer compartment 3.

[0075] like Figure 1 and Figure 6 As shown, the other heat exchange duct section 63 can be formed by the concave second duct cover plate 8 covering the second support beam 32 of the freezer chamber 3. This can increase the contact area between the other heat exchange duct section 63 and the freezer chamber 3. Compared with the line contact of the traditional freezer anti-condensation pipe, the surface contact of the other heat exchange duct section 63 can transfer heat more evenly, thereby better suppressing the formation of condensation on the freezer chamber 3.

[0076] The second air duct cover 8 can be fixed to the second support beam 32 by adhesive bonding. The second support beam 32 can be the middle vertical beam of the refrigerator 1, and it can connect between the aforementioned middle beam 31 and lower front beam 33. The second air duct cover 8 can be fixed to the second support beam 32 by adhesive bonding. By placing another heat exchange air duct section 63 on the middle vertical beam of the refrigerator 1, the travel distance of water vapor can be shortened, preventing water vapor from recondensing in the air duct.

[0077] In some implementations, such as Figure 7 As shown, the aforementioned compressor chamber 5 has a rear cover 4, on which a reserved air vent 42 is provided. The first air inlet 510 on the aforementioned water tray cover 511 is opposite to the reserved air vent 42, allowing air to enter through the reserved air vent 42. When the aforementioned first fan 55 is turned on, the first air inlet 510 on the water tray cover 511 enters through the reserved air vent 42 on the rear cover 4, and the airflow carries the heat emitted by the condenser 56 and the water vapor evaporated from the defrost water in the water tray 59 into the first air outlet duct 54. The second air inlet 41 of the aforementioned first chamber can be provided on the rear cover 4. When the aforementioned second fan 53 is turned on, it can draw the heat generated by the compressor 51 into the aforementioned second air outlet duct 52.

[0078] In some implementations, such as Figure 3 As shown, a first one-way airflow baffle 512 may be provided inside the air inlet 541 of the aforementioned first air outlet duct, allowing air to enter only through the air inlet 541 of the first air outlet duct, so that the airflow is not obstructed and returns. A second one-way airflow baffle may be provided inside the air inlet 521 of the aforementioned second air outlet duct, allowing air to enter only through the air inlet 521 of the second air outlet duct, so that the airflow is not obstructed and returns.

[0079] In some embodiments, the present invention also provides a refrigerator 1, which may include the refrigerator heat dissipation structure described above. Because the refrigerator 1 employs the aforementioned refrigerator heat dissipation structure, the present invention, by additionally adding a water collection tray cover 511 inside the compressor chamber 5 to cover the water collection tray 59 and the condenser 56 within the water collection tray 59, and by separately discharging the water vapor inside the water collection tray cover 511 through the first air outlet duct 54, can reduce the corrosion of electronic components inside the compressor chamber 5 by the water vapor inside the water collection tray 59, thereby improving the service life of the electronic components inside the compressor chamber 5.

[0080] In some embodiments, the refrigerator 1 described above can be a built-in refrigerator. The refrigerator 1 also has a cold storage compartment 2.

[0081] In some embodiments, the present invention also provides a control method for the refrigerator 1 described above. When the refrigerator's heat dissipation structure further includes a second air outlet duct 52 and a second fan 53, and the second air outlet duct 52 is used to communicate with the space inside the compressor compartment 5 outside the water tray cover 511; the space inside the compressor compartment 5 outside the water tray cover 511 is taken as a first chamber, the water tray cover 511 is used to separate the compressor 51 within the first chamber, and the first chamber has a second air inlet 41; the second fan 53 is used to drive airflow, so that the first chamber receives air through the second air inlet 41 and exhausts air through the second air outlet duct 52; and both the first air outlet duct 54 and the second air outlet duct 52 exhaust air through the same exhaust port 310, and a third fan 62 is provided at the air outlet 70; and the refrigerator 1 also has an anti-condensation heater for heating the freezer compartment 3, the above control method includes:

[0082] When compressor 51 starts running, the first fan 55, the second fan 53, and the third fan 62 are activated to quickly dissipate the heat emitted by compressor 51 and condenser 56, preventing overheating of compressor compartment 5 and improving refrigeration efficiency. When compressor 51 stops running, the first fan 55, the second fan 53, and the third fan 62 are each delayed for a preset time before stopping to dissipate residual heat from compressor 51 and condenser 56. After the first fan 55, the second fan 53, and the third fan 62 all stop, the anti-condensation heater is activated to compensate for insufficient heat in the first and second air outlet ducts 54 and 52 during the compressor 51 shutdown period, which makes it difficult to suppress condensation formation in the freezer compartment 3.

[0083] It should be noted that the aforementioned anti-condensation heater can be attached to the heat exchange duct section 6 of the aforementioned second air outlet duct 52 and / or installed in another heat exchange duct section 63 of the aforementioned first air outlet duct 54.

[0084] In this invention, the design of the fan and air outlet duct enables the rapid discharge of heat emitted by the compressor 51 and condenser 56, preventing overheating of the compressor compartment 5 and improving refrigeration efficiency. Simultaneously, water vapor evaporated from the drip tray 59 is discharged through the first air outlet duct 54, reducing the humid environment at the back of the refrigerator 1 and preventing mold growth. Furthermore, the design of the heat exchange duct sections 6 on both the first and second air outlet ducts 54 replaces the traditional anti-condensation pipe, utilizing the hot air discharged from the compressor compartment 5 to prevent condensation in the freezer compartment 3. The larger contact area between each heat exchange duct section 6 and the freezer compartment 3, compared to the line contact of traditional anti-condensation pipes, allows for more uniform heat transfer, thus better suppressing condensation formation.

[0085] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.
