Description

Technical Field

[0001] This invention relates to a refrigeration device. Background Technology

[0002] Existing refrigeration equipment typically uses air cooling to improve refrigeration efficiency. Such equipment generally includes at least a refrigerator compartment and a freezer compartment. Cold air, cooled by the evaporator, flows through ducts to the refrigerator and freezer compartments, respectively, with air outlets for the incoming cold air. Because the cold air is very cold after being cooled by the evaporator, when it enters the refrigerator compartment directly through the air outlets, items stored there, such as vegetables and fruits, are easily damaged by the extremely low temperature air, especially items placed near the air outlets. Simultaneously, the moisture in vegetables and fruits is lost more quickly, making them more prone to drying out. This is particularly problematic when a large amount of food is placed in the refrigerator compartment at once, requiring continuous cooling for extended periods; items near the air outlets are even more susceptible to freezing and drying out.

[0003] In addition, as users' storage needs gradually increase, the capacity of refrigeration equipment is also getting larger and larger. More compartments are usually set up to meet the needs. The refrigerator compartment is usually located above or to one side of the freezer compartment, while the compressor compartment and cooling compartment are usually located below the refrigeration equipment. As a result, the refrigeration air duct will occupy the entire rear space of the freezer compartment, and the return air duct of the refrigerator compartment extends throughout the entire space of the refrigeration equipment. The entire return air duct is relatively long, and the volume of the refrigerator and freezer compartments will inevitably be limited.

[0004] In view of this, it is necessary to improve the existing refrigeration equipment to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a refrigeration device that can effectively prevent frozen food in a refrigerator.

[0006] To achieve the above-mentioned objectives, the present invention provides a refrigeration device, which includes a storage room and a cooling room. The storage room includes a refrigerator room and a freezer room arranged side by side in a left-right direction. The refrigeration device further includes a mixing structure located behind the refrigerator room and defining a mixing chamber, an air supply duct connecting the cooling room and the mixing chamber to allow the cooled air in the cooling room to enter the mixing chamber, an air inlet duct connecting the refrigerator room and the mixing chamber to introduce air from the refrigerator room into the mixing chamber, and an air outlet for delivering the mixed cold air in the mixing chamber to the refrigerator room.

[0007] As a further improvement of the present invention, the air mixing structure includes a front wall and a rear wall disposed opposite to each other in the front-rear direction, and the front wall is provided with an air outlet formed by passing through it in the front-rear direction.

[0008] As a further improvement of the present invention, the air outlet includes a first air outlet located on the upper side and a second air outlet located on the lower side, with the first air outlet disposed adjacent to the upper edge of the air mixing structure.

[0009] As a further improvement of the present invention, both the first air outlet and the second air outlet are arranged to face forward, and the width of the first air outlet in the horizontal direction is greater than the width of the second air outlet in the horizontal direction.

[0010] As a further improvement of the present invention, the air mixing structure also has a partition wall located between the front wall and the rear wall in the front-rear direction, the partition wall being located on the side of the air mixing structure near the cooling chamber and separating the air supply duct and the air intake duct.

[0011] As a further improvement of the present invention, the air mixing structure also has a partition located inside the mixing chamber and connecting the front wall and the rear wall, the partition having a protrusion extending toward the air supply duct.

[0012] As a further improvement of the present invention, the partition divides the mixing chamber into a first mixing region and a second mixing region, the first mixing region and the second mixing region being connected on the side near the cooling chamber.

[0013] As a further improvement of the present invention, the cooling chamber is located on the upper side of the back of the freezer compartment, and the mixing chamber is located on the upper part of the back of the refrigerator compartment.

[0014] As a further improvement of the present invention, the air mixing structure has a drainage groove located on its lower side, the drainage groove passing through the air mixing structure in the vertical direction to discharge the condensation formed in the mixing chamber outward.

[0015] As a further improvement of the present invention, the air mixing structure has an inclined surface located on its lower side and set at an angle to the vertical plane, and the outlet end of the drainage channel is opened on the inclined surface.

[0016] The beneficial effects of the present invention are as follows: The refrigeration equipment of the present invention has a mixing structure component installed on the rear side of the refrigeration compartment. The cold air sent from the cooling compartment and the air introduced into the refrigeration compartment are mixed in the mixing chamber of the mixing structure component. The mixed cold air is then sent to the refrigeration compartment through the air outlet provided on the mixing structure component. This avoids the problem of the cold air temperature sent to the refrigeration compartment being too low, which would cause the items in the refrigeration compartment to freeze and / or dry out.

[0045] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0046] The terms used herein, such as “up,” “down,” “left,” “right,” “front,” and “back,” indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures and should not be construed as limiting the claims. Furthermore, the descriptive term “horizontal” used herein is not entirely equivalent to being perpendicular to the direction of gravity and allows for a certain angle of inclination.

[0047] Please refer to Figures 1 to 2 The diagram shown is a schematic of the refrigeration device 100 of the present invention. Figures 3 to 16 This is a first embodiment of the refrigeration device 100. Figures 17 to 19 This is a second embodiment of the refrigeration device 100, wherein... Figures 7 to 8 This is one embodiment of the refrigerated return air duct 71 of the refrigeration equipment 100. Figure 9 This is another embodiment of the refrigerated return air duct 71 of the refrigeration equipment.

[0048] Please refer to Figures 1 to 6 As shown, the refrigeration device 100 includes a storage compartment 10 and a cooling compartment 20. In the embodiment shown in this invention, the storage compartment 10 has a drawer 14 located at its lower part and a support structure 15 located at its upper part for supporting items.

[0049] Specifically, the storage room 10 includes a refrigerator compartment 11 and a freezer compartment 12 arranged side by side in the left-right direction, and the refrigerator compartment 11 and the freezer compartment 12 are separated by the central beam 13 of the refrigeration equipment 100.

[0050] The refrigeration equipment 100 is further provided with a mixing structure 30 located behind the refrigerator compartment 11 and defining a mixing chamber 301; an air supply duct 4 connecting the cooling compartment 20 and the mixing chamber 301 to allow the cooled air in the cooling compartment 20 to enter the mixing chamber 301; an air inlet duct 5 connecting the refrigerator compartment 11 and the mixing chamber 301 to introduce air from the refrigerator compartment 11 into the mixing chamber 301; and an air outlet 312 that delivers the mixed cold air in the mixing chamber 301 to the air outlet in the refrigerator compartment 11. Thus, the cooling compartment 20 and the refrigerator compartment 11 are connected through the mixing chamber 301.

[0051] In some embodiments, the air mixing structure 30 includes a front wall 31 and a rear wall 32 disposed opposite to each other in the front-rear direction, and the front wall 31 is provided with an air outlet 312 formed through it in the front-rear direction.

[0052] The air outlet 312 includes a first air outlet 3121 located on the upper side and a second air outlet 3122 located on the lower side. The first air outlet 3121 is disposed near the upper edge of the air mixing structure 30.

[0053] like Figure 9 As shown, both the first air outlet 3121 and the second air outlet 3122 are arranged facing forward, and the width of the first air outlet 3121 in the horizontal direction is greater than the width of the second air outlet 3122 in the horizontal direction. Figure 14 As shown, the opening size of the second air outlet 3122 in the height direction is smaller than the opening size of the first air outlet 3121 in the height direction. In this embodiment, there is a distance between the second air outlet 3122 and the lower end face of the air mixing structure 30.

[0054] When the refrigerator compartment 11 is provided with a functional area 112, the air outlet 312 further includes a third air outlet 3123 located below the second air outlet 3122 in the height direction, and the third air outlet 3123 is arranged to open downwards. In addition, the refrigeration equipment 100 also has a duct 75 connected to the third air outlet 3123.

[0055] The air mixing structure 30 also has a partition wall 34 located between the front wall 31 and the rear wall 32 in the front-rear direction. The partition wall 34 is located on the side of the air mixing structure 30 near the cooling chamber 20 and separates the air supply duct 4 and the air inlet duct 5.

[0056] The air supply duct 4 is located behind the air inlet duct 5, and the air supply duct 4 includes a first air supply section 41 connecting the air mixing structure 30 and the cooling chamber 20, and a second air supply section 42 formed on the air mixing structure 30. The second air supply section 42 is defined by the partition wall 34 and the rear wall 32. The side end face of the partition wall 34 near the cooling chamber 20 is not flush with the side end face of the rear wall 32 near the cooling chamber 20, and the side end face of the partition wall 34 near the cooling chamber 20 is closer to the cooling chamber 20 than the side end face of the rear wall 32 near the cooling chamber 20. That is, the partition wall 34 extends beyond the side end face of the rear wall 32 in the left-right direction toward the cooling chamber 20, so that the partition wall 34 has a stepped portion 3412 protruding from the rear wall 32.

[0057] Specifically, the partition wall 34 includes a first straight wall 341, a connecting wall 342, and a second straight wall 343 connected in sequence. The stepped portion 3412 is formed at the end of the first straight wall 341 and is located on the side of the first straight wall 341 away from the connecting wall 342. The first straight wall 341 and the second straight wall 343 are offset in the front-rear direction so that the connecting wall 342 is inclined, and the first straight wall 341 is located in front of the second straight wall 343 in the front-rear direction.

[0058] The second straight wall 343 has an end face 3431 located at one end away from the connecting wall 342. The end face 3431 is inclined, and the rear end of the end face 3431 is away from the connecting wall 342, while the front end is close to the connecting wall 342, thereby effectively preventing the cold air from the cooling chamber 20 from being blown directly out of the air inlet duct 5 without mixing.

[0059] The first air supply section 41 includes a straight section 411 connected to the second air supply section 42 and an inclined section 412 connecting the straight section 411 to the cooling chamber 20. The end of the inclined section 412 connected to the cooling chamber 20 is located in front of the end connected to the straight section 411 in the front-back direction, so that the straight section 411 is located behind the refrigeration air outlet of the cooling chamber 20.

[0060] The rear wall 32 has a recessed portion 321 on the side near the cooling chamber 20, recessed from its front surface backwards. The recessed portion 321 is spaced apart from the end face of the rear wall 32 near the cooling chamber 20 in the left-right direction. The recessed portion 321 is correspondingly positioned to the second straight wall 343 to avoid the second air supply section 42 becoming narrower at this location due to the rearward offset of the second straight wall 343. The second air supply section 42 has its largest front and rear openings at the portion adjacent to the first air supply section 41 to facilitate the reception of cold air from the first air supply section 41.

[0061] The air inlet duct 5 and the air outlet duct 4 are located on the same side of the air mixing structure 30 in the left-right direction. Specifically, the air inlet duct 5 includes a first air inlet section 51 located near the cooling chamber 20, a second air inlet section 52 located away from the cooling chamber 20, and third and fourth air inlet sections 53 and 54 located between the first air inlet section 51 and the second air inlet section 52. The first air inlet section 51 is defined by the partition wall 34 and the cover 6.

[0062] The diameter of the second air inlet section 52 in the front-to-back direction is smaller than that of the adjacent third air inlet section 53. The opening size of the first air inlet section 51 in the front-to-back direction is smaller than that of the adjacent fourth air inlet section 54 in the front-to-back direction. Furthermore, the opening size of the first air inlet section 51 in the front-to-back direction is smaller than that of the first air inlet section 51. In other words, the first air inlet section 51 is the narrowest part of the entire air inlet duct 5, thereby effectively controlling the airflow from the refrigerator compartment 11 into the mixing chamber 301.

[0063] like Figures 10 to 13 As shown, the mixing structure 30 also has a partition 35 located inside the mixing chamber 301 and connecting the front wall 31 and the rear wall 32. The partition 35 divides the mixing chamber 301 into a first mixing region 3011 and a second mixing region 3012. The first mixing region 3011 and the second mixing region 3012 are connected on the side near the cooling chamber 20.

[0064] Furthermore, the partition 35 has a protrusion 351 extending toward the air supply duct 4. In this embodiment, the protrusion 351 is disposed near the bottom end of the mixing structure 30 in the height direction, so that the receiving space of the first mixing region 3011 is larger than the receiving space of the second mixing region 3012.

[0065] The partition 35 has a first side edge 352 and a second side edge 353 that are arranged opposite each other in the height direction. The first and second side edges 352 and 353 are both concave arc shapes so as to make the mixing space on both sides of the partition 35 larger.

[0066] like Figure 15 As shown, the first air outlet 3121 is connected to the first mixing region 3011 from front to back, and the second air outlet 3122 is connected to the second mixing region 3012 from front to back. The first mixing region 3011 has a connecting channel 3013 located on its upper side and connected to the first air outlet 3121, and a first vertical channel 3014 located on its lower side and extending in a vertical direction. The connecting channel 3013 is inclined and set at an angle to the first vertical channel 3014, and the opening width of the connecting channel 3013 is greater than the opening height of the first air outlet 3121.

[0067] The second mixing region 3012 includes a second vertical channel 3015 extending vertically on its upper side and a narrowing channel 3016 located on its lower side and connected to the second air outlet 3122. The narrowing channel 3016 is connected forward to the second air outlet 3122 and downward to the third air outlet 3123. The upper part of the narrowing channel 3016 has a larger opening size in the front-back direction than the lower part has a larger opening size in the front-back direction.

[0068] Furthermore, such as Figures 1 to 4 As shown, in some embodiments, the refrigeration device 100 has a double-door structure, the cooling chamber 20 is located on the upper side of the back of the freezer chamber 12, and the mixing chamber 301 is located on the upper part of the back of the refrigerator chamber 11.

[0069] The air mixing structure 30 also has a drainage groove 36 located on its lower side, which runs through the air mixing structure 30 in the vertical direction to discharge the condensation formed in the mixing chamber outward.

[0070] In addition, the air mixing structure 30 is provided with an inclined surface 302 located on its lower side and angled to the vertical plane, and the outlet end of the drainage channel 36 is opened on the inclined surface 302. In this way, the opening of the outlet end of the drainage channel 36 is enlarged, which facilitates the rapid discharge of water.

[0071] In some embodiments, the drainage groove 36 is connected to the air inlet duct 5, and the projection of the drainage groove 36 on the horizontal plane falls within the projection of the air inlet duct 5 on the horizontal plane. The drainage groove 36 is located on the side of the second air outlet 3122 closer to the cooling chamber 20 in the left-right direction, and the lower edge of the drainage groove 36 on the inclined surface 302 is located below the second air outlet 3122. In addition, the second air outlet 3122 is located within the extension range of the inclined surface 302 in the height direction.

[0072] In some embodiments, the refrigeration system of the refrigeration device 100 is a single refrigeration system consisting of an evaporator 21 and a fan 22. Through connections such as air ducts, each temperature zone can be refrigerated independently. Furthermore, the multi-path airflow ducts for freezing and refrigeration ensure more uniform temperature distribution and less temperature fluctuation within each compartment. Additionally, the fan 22 operates intermittently; when operating normally, it blows cold air from the cooling chamber 20 into the refrigeration chamber 11 and the freezer chamber 12.

[0073] The refrigeration equipment 100 also has a refrigeration air supply duct 72 and a refrigeration air return duct 73 that connect the cooling chamber 20 and the freezing chamber 12. The refrigeration air supply duct 72 delivers the cooled air in the cooling chamber 20 to the freezing chamber 12, and the refrigeration air return duct 73 returns the air in the freezing chamber 12 to the cooling chamber 20.

[0074] The refrigeration equipment 100 also has a first return air duct that returns air from the refrigerator compartment 11 to the cooling compartment 20. The refrigerator return air duct 71 defines the first return air duct. In some embodiments, the refrigerator return air duct 71 is disposed within the central beam 13.

[0075] The upper end of the refrigerated return air duct 71 is the return air outlet 7101, and the lower end is the return air inlet 7102. The return air outlet 7101 is connected to the bottom of the cooling chamber 20 and is located on one side of the cooling chamber 20 in the left-right direction.

[0076] The refrigerated return air duct 71 has a main pipe 711 extending along the height direction and a connecting pipe 712 connected to the top end of the main pipe 711. The return air outlet 7101 is located at the end of the connecting pipe 712 connected to the cooling chamber 20. The connecting pipe 712 is set at an angle to the main pipe 711.

[0077] like Figure 4 , Figure 7 and Figure 8 As shown, the connecting pipe 712 is inclined, and the end of the connecting pipe 712 connected to the main pipe 711 is higher than the end connected to the cooling chamber 20. This allows water vapor in the connecting pipe 712 to flow downward into the water collection tray below the evaporator 21, preventing it from flowing into the refrigerator compartment 11.

[0078] In addition, the refrigerated return air duct 71 also has a branch duct 713 extending from the main duct 711. The connecting duct 712 and the branch duct 713 are respectively placed on the left and right sides of the main duct 711. When the fan 22 is running normally, the air in the refrigerated compartment 11 enters the branch duct 713 and the main duct 711 through the secondary return air inlet 7103 of the branch duct 713 and the return air inlet 7102 of the main duct 711, and then flows into the cooling compartment 20.

[0079] like Figure 8 As shown, in some embodiments of the present invention, the refrigeration compartment 11 does not need to be provided with a functional area 112. In this case, the connection part of the connecting pipe 712 and the main pipe 711 is provided with an upwardly protruding baffle 714. The baffle 714 is located inside the refrigeration return air duct 71 to partially separate the connecting pipe 712 and the main pipe 711.

[0080] Furthermore, the baffle 714 extends upward from the wall of the refrigerated return air duct 71 and extends in the front-to-back direction. Thus, when the refrigerated compartment 11 does not have the functional area 112 and when the fan 22 stops operating, the baffle 714 can prevent cold air in the cooling chamber 20 from flowing into the refrigerated return air duct 71 during defrosting of the evaporator 21.

[0081] like Figure 9 As shown, in some other embodiments of the present invention, a functional area 112 is provided in the refrigerator compartment 11. In this case, there is no need to install baffles or similar structures in the connecting pipe 712 of the refrigerator return air duct 71. When the fan 22 stops running and the evaporator 21 defrosts, the cold air in the cooling chamber 20 can sink from the refrigerator return air duct 71 and be sent to the functional area 112 located in the lower part of the refrigerator compartment 11.

[0082] In other words, when the refrigerator compartment 11 is equipped with a functional area 112, and when the fan 22 stops operating, the cooled air in the cooling chamber 20 flows into the lower part of the refrigerator compartment 11 through the refrigerator return air duct 71.

[0083] The refrigeration equipment 100 also has a drain pipe 74 connected to the cooling chamber 20 to discharge water from the cooling chamber 20 to the outside, and the refrigerated return air duct 71 is disposed close to the drain pipe 74. The water inlet of the drain pipe 74 is lower in height than the return air outlet 7101 of the refrigerated return air duct 71.

[0084] In such Figures 3 to 6 In one embodiment shown, the refrigerated return air duct 71 and the drain pipe 74 are independent of each other and arranged side by side, and the drain pipe 74 extends downward beyond the bottom end of the refrigerated return air duct 71.

[0085] In such Figure 9 and Figure 17 In another embodiment shown, the drain pipe 74 extends into the refrigerated return air duct 71 and includes a first drain section 741 located on the upper side and a second drain section 742 located on the lower side. The first drain section 741 connects the cooling chamber 20 to the refrigerated return air duct 71, and the second drain section 742 extends downward from the bottom end of the refrigerated return air duct 71. The first drain section 741 is connected to the refrigerated return air duct 71 in the left-right direction on the side closer to the cooling chamber 20.

[0086] In this invention, the refrigeration equipment 100 mixes the cold air from the cooling chamber 20 and the air introduced into the refrigeration chamber 11 in the mixing chamber 301 of the mixing structure 30 by setting the mixing structure 30 on the rear side of the refrigeration chamber 11. The mixed cold air is then sent into the refrigeration chamber 11 through the air outlet 312 provided on the mixing structure 30. This avoids the problem of the cold air temperature in the refrigeration chamber 11 being too low, which would cause the items in the refrigeration chamber to freeze and / or dry out. At the same time, it allows the airflow to circulate along the walls of the chamber in a large circulation, avoiding direct blowing.

[0087] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0088] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
