[0037] A freezer is a specialized storage device used to store various items that require refrigeration. It keeps food and other items frozen and is available in both home and commercial formats. A freezer's refrigeration system consists of a compressor, condenser, capillary tubes, and evaporator. Through the continuous circulation of refrigerant, heat is drawn from the freezer to the outside, achieving a cooling effect.

[0038] To reduce condensation inside the freezer, air cooling can be used. The fan circulates the cold air to ensure that the food and drinks are kept at a roughly consistent temperature throughout the freezer.

[0039] In the related art, the return air path in the air duct module is short, which results in a short cooling time, thereby causing insufficient cooling capacity of the gas and poor cooling effect during the circulation process.

[0040] In the related art, the air duct module is arranged inside the refrigerator.

[0041] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0042] See also Figure 1 The embodiment of the present application provides an air duct module 100. The air duct module 100 provided in the embodiment of the present application is mainly used in refrigeration equipment. The air duct module 100 provided in the embodiment of the present application enables the gas in the refrigeration equipment to circulate and improve the refrigeration effect of the entire refrigeration equipment.

[0043] The refrigeration device may be a refrigerator or a freezer, and specifically, the freezer may be a horizontal freezer 10 or a vertical freezer. In the embodiments of the present application, for convenience of description, the horizontal freezer 10 is used as an example for explanation, and the same can be applied to other devices.

[0044] See also Figure 2 and Figure 3 The chest freezer 10 is roughly a rectangular parallelepiped. For ease of description, the height direction Z, width direction X, and thickness direction Y are defined separately. When the chest freezer 10 is in use, the vertical direction is the height direction Z, and the projection of the chest freezer 10 in the vertical direction is a rectangle. The direction along which the long side lies is the width direction X, and the direction along which the wide side lies is the thickness direction Y.

[0045] Since the thickness of the air duct module 100 is smaller than its width, and the width of the air duct module 100 is substantially equal to the thickness of the horizontal freezer 10, the air duct module 100 can be installed on a side of the horizontal freezer 10 in the width direction X, so that the air blown out of the freezer can cover the side formed by the length direction and the width direction X as much as possible. This allows the air blown out of the freezer to cover the entire interior of the cabinet 200, thereby improving the uniformity of freezing as much as possible.

[0046] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, the direction closest to the opening is up, and the direction closest to the bottom surface 213 is down. In the width direction X, the directions are left and right, respectively. The installation location of the duct module 100 is right, and the opposite side is left. In the thickness direction Y, the connection between the door 230 and the main body 220 is back, and the opposite side is front.

[0047] See also Figure 4 In some embodiments, the air duct module 100 includes: a front shell 121, a rear shell and a guide member 130. The front shell 121 includes a first shell segment 121a, a second shell segment 121b and a third shell segment 121c. The second shell segment 121b is respectively connected to the first shell segment 121a and the third shell segment 121c; the rear shell 123 is connected to the first shell segment 121a to form an installation cavity 124; the guide member 130 is arranged in the installation cavity 124, which can allow external gas to enter the installation cavity 124 and the gas in the installation cavity 124 to flow out of the installation cavity 124; wherein, the third shell segment 121c is protruded from the second shell segment 121b, and the third shell segment 121c is provided with a return air port 114.

[0048] The air duct module 100 is applied to the refrigeration equipment (horizontal freezer 10) and is installed in the cabinet 200 of the refrigeration equipment (horizontal freezer 10). It can make the air in the refrigeration equipment (horizontal freezer 10) flow, so that the air in the refrigeration equipment (horizontal freezer 10) can be blown toward the frozen items after being cooled by the evaporator 320. That is, it can be considered that the air duct module 100 is mainly used to blow cold air into the refrigeration equipment (horizontal freezer 10), so that the cold air can circulate inside the refrigeration equipment (horizontal freezer 10), and ensure that the temperature in the same chamber of the refrigeration equipment (horizontal freezer 10) is roughly the same as much as possible, thereby reducing the temperature difference in the same chamber.

[0049] The front shell 121 and the rear shell 123 form the housing 120. The housing 120 is the primary structure of the entire duct module 100 and serves as its foundation, providing a mounting base for other components of the duct module 100. Structures such as the flow guide 130 can be mounted on the housing 120, forming a cohesive unit for the duct module 100 and facilitating its installation and transportation. Furthermore, the housing 120 protects the flow guide 130 and other components, minimizing damage to them from external structures.

[0050] The flow guide 130 is mainly used for disturbing the flow so that the air can circulate in the refrigeration device, that is, the air in the refrigeration device can continuously flow to the evaporator 320, and then be blown to the frozen items again after being cooled by the evaporator 320.

[0051] The flow guiding member 130 may be a fan, specifically, a centrifugal fan, an axial flow fan, or a cross flow fan.

[0052] The third shell segment 121c protrudes from the second shell segment 121b. This means that the third housing 120 protrudes from the second shell segment 121b in the width direction X. Specifically, the third shell segment 121c is positioned to the left of the second shell segment 121b in the width direction X, closer to the center of the chest freezer 100. The return air vent 114 is positioned in the third shell segment 121c. This position can be considered closer to the center of the accommodating chamber 211 in the width direction X. This allows the gas within the accommodating chamber 211 to more easily enter the air duct module 100 through the return air vent 114. This allows the gas to remain within the air duct module 100 for an extended period, thereby increasing the heat exchange time with the evaporator 320, improving the cooling effect on the air, and thus, the freezing effect.

[0053] In some embodiments, the return air port 114 is disposed at an end of the third shell segment 121 c away from the second shell segment 121 b .

[0054] The third shell segment 121c protrudes from the second shell segment 121b, meaning that the third housing 120 protrudes from the second shell segment 121b in the width direction X. Specifically, the third shell segment 121c is positioned to the left of the second shell segment 121b in the width direction X, closer to the center of the accommodating chamber 211. The return air port 114 is positioned at the end of the third shell segment 121c away from the second shell segment 121b, and the first air outlet 112 is positioned on the first shell segment 121a. It can be considered that, in the width direction X, of the return air port 114 and the first air outlet 112, the return air port 114 is positioned closer to the center of the accommodating chamber 211. This allows the gas within the accommodating chamber 211 to more easily enter the fixed chamber 125 through the return air port 114, allowing the gas to remain in the fixed chamber 125 for an extended period. This increases the heat exchange time with the evaporator 320, improves the cooling effect on the air, and thus enhances the freezing effect.

[0055] In some embodiments, the first shell segment 121a, the second shell segment 121b, and the third shell segment 121c are integrally formed.

[0056] The integral molding of the first shell segment 121a, the second shell segment 121b, and the third shell segment 121c can be performed by injection molding or stamping, and the specific molding method is not limited. The integral molding of the first shell segment 121a, the second shell segment 121b, and the third shell segment 121c allows the entire front shell 121 to be molded in a single step, thereby reducing the assembly steps between the first shell segment 121a, the second shell segment 121b, and the third shell segment 121c, and thus reducing the cost of the entire front shell 121.

[0057] In some embodiments, the first shell segment 121a and the second shell segment 121b are coplanar, which means that the first shell segment 121a and the second shell segment 121b can be a whole, that is, the first shell segment 121a and the second shell segment 121b can be vertically arranged in the height direction Z, and the first shell segment 121a is located above the second shell segment 121b, and in the width direction X, the first shell segment 121a and the second shell segment 121b have the same thickness, so that the second shell segment 121b can occupy as little space as possible in the accommodating cavity 211 of the horizontal freezer 10, leaving more space for items to be frozen.

[0058] The first air outlet 112 is located above the second air outlet 113 , and the second air outlet 113 is located above the return air outlet 114 .

[0059] Among them, the first air outlet 112, the second air outlet 113 and the return air outlet 114 are arranged in sequence from high to low, the first air outlet 112 is close to the top of the accommodating cavity 211, the return air outlet 114 is close to the bottom of the accommodating cavity 211, and the second air outlet 113 is roughly arranged in the middle area of the accommodating cavity 211, so that the cold air can form multiple different circulation areas, thereby improving the cooling effect.

[0060] Specifically, when users place items, they basically stack them from bottom to top. There are more items at the bottom and more cooling is required. A second air outlet 113 is set between the first air outlet 112 and the return air outlet 114, so that the cold air can be discharged roughly from the middle area of the cabinet 200 and can be blown to the bottom area of the accommodating cavity 211 as quickly as possible. Through the cooperation of the first air outlet 112 and the second air outlet 113, the cold air can be blown more evenly to different areas in the accommodating cavity 211, thereby achieving a better cooling effect.

[0061] The air duct module 100 is disposed on one side of the accommodating chamber 211 in the width direction X, with the first air outlet 112 disposed approximately at the top of the accommodating chamber 211 and the second air outlet 113 disposed approximately in the middle of the accommodating chamber 211. Since it is less likely that items will be placed at the top of the accommodating chamber 211, the cold air blown out from the first air outlet 112 can be blown as far as possible toward the other side of the accommodating chamber 211 in the width direction X, allowing the cold air to reach areas farther from the air duct module 100. The second air outlet 113 is disposed approximately in the middle of the accommodating chamber 211, allowing the cold air blown out from the second air outlet 113 to blow directly onto items near the air duct module 100. This allows the cold air to reach as many items in the accommodating chamber 211 as possible, thereby improving the cooling effect of the entire horizontal freezer 10.

[0062] That is to say, in the embodiment of the present application, the first air outlet 112 is located above the second air outlet 113, and the first air outlet 112 and the second air outlet 113 can be located on the same side of the shell 120, so that the first air outlet 112 and the second air outlet 113 can discharge air along the width direction X of the cabinet 200, so that the cold air can flow in the width direction X of the cabinet 200 as much as possible, and can be blown to farther places, so that items in different areas can be blown with cold air, thereby reducing the uneven temperature inside the cabinet 200 as much as possible and improving the cooling effect.

[0063] In some embodiments, the housing 120 has a first surface 126a and a second surface 126b that are disposed at an angle to each other. The first air outlet 112 is located on the first surface 126a and the second surface 126b, respectively.

[0064] Among them, the first surface 126a is located at the top of the shell 120, the second surface 126b is located on the side of the shell 120, and the first air outlet 112 extends from the first surface 126a to the second surface 126b, so that part of the first air outlet 112 is located at the top of the shell 120 and part is located on the side of the shell 120. The middle transition area is connected by an arc transition, so that the entire first air outlet 112 is arc-shaped.

[0065] In some embodiments, there are multiple first air outlets 112, and the multiple first air outlets 112 are located at the same height of the air duct module 100. The multiple first air outlets 112 are all arc-shaped. That is, the cross-sections of the multiple first air outlets 112 in the vertical plane are all arc-shaped. The curvature of the multiple first air outlets 112 can be the same or different, and can be set according to actual conditions.

[0066] Multiple first air outlets 112 are arranged in sequence at intervals in the thickness direction Y, so that the first air outlets 112 are provided as evenly as possible in the thickness direction Y of the cabinet 200, so that the air blown out from the multiple first air outlets 112 can cover the plane formed by the width direction X and the thickness direction Y as much as possible, thereby increasing the coverage area of the cold air and thus improving the cooling effect.

[0067] In some embodiments, the second air outlet 113 is located on the second surface 126b. This allows the first air outlet 112 and the second air outlet 113 to be located on the same side of the housing, allowing the first air outlet 112 and the second air outlet 113 to discharge air along the width direction X of the cabinet 200. This allows the cold air to flow as much as possible in the width direction X of the cabinet 200 and reach further, allowing items in different areas to be blown by the cold air, thereby minimizing temperature unevenness inside the cabinet 200 and improving the cooling effect.

[0068] See also Figure 5 、 Figure 6 、 Figure 7 In some embodiments, the first air outlet 112 is at least partially curved. The first air outlet 112 is located at the top of the housing 120. The first air outlet 112 may be at least partially curved. The first air outlet 112 may be entirely curved, or part of the first air outlet 112 may be curved while the other part may be linear. The specific embodiment is not limited thereto.

[0069] The first air outlet 112 is located at the top of the shell 120 and is arc-shaped. The arc-shaped first air outlet 112 has multiple different air outlet directions. Since the first air outlet 112 is located at the top of the shell 120, the cold air blown out by the first air outlet 112 can blow upward and left, so that the upward cold air can flow to the left side of the cabinet 200 after passing through the guidance of the door body 230, and the cold air to the left can be blown directly to the area near the air duct module 100, so that the cold air can flow as much as possible inside the entire cabinet 200, thereby improving the cooling effect.

[0070] In some embodiments, the curvature of the first air outlet 112 is 80 to 100 degrees. The curvature of the first air outlet 112 refers to the curvature in the vertical plane. Specifically, the curvature of the first air outlet 112 can be 80 degrees, 82 degrees, 85 degrees, 90 degrees, 95 degrees, etc.

[0071] The curvature of the first air outlet 112 is 80 degrees to 100 degrees, so that the first air outlet 112 can cover the top and left side of the air duct module 100 as much as possible, so that the first air outlet 112 can have a vertical upward air outlet direction at the top of the shell 120 as much as possible, and a horizontal upward and left air outlet direction at the side of the shell 120. At the same time, it also has multiple inclined upward and left air outlet directions from vertical upward to horizontal left, so that the cold air can flow to different areas in the cabinet 200, so that the cold air can circulate in the cabinet 200, thereby improving the cooling effect.

[0072] See also Figure 8 In some embodiments, the return air outlet 114 is tilted, which means that the return air outlet 114 is tilted in the height direction of the cabinet 200. For the convenience of description, the return air outlet 114 is defined as having a first side 114a and a second side 114b that are relatively arranged, and the second side 114b is located above the first side 114a. Along the height direction Z of the cabinet 200, the return air outlet 114 is tilted, which means that the first side 114a and the second side 114b are staggered in the width direction X or the thickness direction Y, that is, along the height direction Z, the projections of the first side 114a and the second side 114b on the bottom surface 213 are staggered.

[0073] Specifically, the inclination direction of the return air outlet 114 can be toward the bottom surface 213 of the accommodating cavity 211 (that is, the second side 114b is set on the left side of the first side 114a), or it can be toward the opening of the accommodating cavity 211 (that is, the first side 114a is set on the left side of the second side 114b).

[0074] The return air outlet 114 is tilted so that it has a certain angle in the height direction Z. A smaller cavity can be formed below the return air outlet 114, thereby providing space for the gas in the accommodating cavity 211 to flow toward the return air outlet 114, reducing the risk of the return air outlet 114 being blocked, allowing cold air to circulate in the accommodating cavity 211, and improving the cooling effect of the entire horizontal freezer 10.

[0075] In some embodiments, the return air vent 114 is disposed toward the bottom surface 213, meaning that the return air vent 114 is disposed obliquely downward, i.e., the second side 114b is disposed above the first side 114a and to the left of the first side 114a. The return air vent 114 is disposed toward the bottom surface 213 so that the return air direction of the return air vent 114 has a downward return air direction trend.

[0076] In some embodiments, the first air outlet 112 is at least partially curved. The first air outlet 112 is located at the top of the housing 120. The first air outlet 112 is at least partially curved. The first air outlet 112 can be completely curved, or a portion of the first air outlet 112 can be curved and another portion can be linear. There is no specific limitation.

[0077] The first air outlet 112 is located at the top of the shell 120 and is arc-shaped. The arc-shaped first air outlet 112 has multiple different air outlet directions. Since the first air outlet 112 is located at the top of the shell 120, the cold air blown out by the first air outlet 112 can blow upward and left, so that the upward cold air can flow to the left side of the cabinet 200 after passing through the guidance of the door body 230, and the cold air to the left can be blown directly to the area near the air duct module 100, so that the cold air can flow as much as possible inside the entire cabinet 200, thereby improving the cooling effect.

[0078] In some embodiments, the curvature of the first air outlet 112 is 80 to 100 degrees. The curvature of the first air outlet 112 refers to the curvature in the vertical plane. Specifically, the curvature of the first air outlet 112 can be 80 degrees, 82 degrees, 85 degrees, 90 degrees, 95 degrees, etc.

[0079] The curvature of the first air outlet 112 is 80 degrees to 100 degrees, so that the first air outlet 112 can cover the top and left side of the air duct module 100 as much as possible, so that the first air outlet 112 can have a vertical upward air outlet direction at the top of the shell 120 as much as possible, and a horizontal upward and left air outlet direction at the side of the shell 120. At the same time, it also has multiple inclined upward and left air outlet directions from vertical upward to horizontal left, so that the cold air can flow to different areas in the cabinet 200, so that the cold air can circulate in the cabinet 200, thereby improving the cooling effect.

[0080] Based on the same concept, the present application also provides a horizontal refrigerator. Figure 3 and Figure 9 Based on the same inventive concept, an embodiment of the present application further provides a horizontal freezer 10 , which includes a cabinet body 200 and an air duct module 100 . The cabinet body 200 has an accommodating cavity 211 for accommodating the air duct module 100 .

[0081] The horizontal freezer 10 is mainly used for refrigerating items. The cabinet body 200 is the main body 220 structure of the entire horizontal freezer 10. It can provide an installation basis for structures such as the air duct module 100, compressor 310, evaporator 320, condenser, etc., and can also protect the above-mentioned electronic components.

[0082] The cabinet 200 includes a main body 220 and a door 230 connected to the main body 220. The door 230 covers the opening of the main body 220. A refrigerated chamber 211 is provided within the main body 220, and the items to be refrigerated are placed within the refrigerated chamber 211. The cold air blown out by the air duct module 100 freezes the items. The main body 220 includes an inner liner 221 and an outer shell 223. The space between the inner liner 221 and the outer shell 223 is filled with a foam layer. An electrical chamber 215 is located between the inner liner 221 and the outer shell 223, which accommodates the compressor 310. The electrical control box is also located within the electrical chamber 215.

[0083] The air duct module 100 is arranged in the accommodating cavity 211, and the first air outlet 112, the second air outlet 113 and the return air outlet 114 are all connected to the accommodating cavity 211. The air duct module 100 blows the cold air after being cooled by the evaporator 320 from the first air outlet 112 and the second air outlet 114 into the accommodating cavity 211. The gas in the accommodating cavity 211 can return to the vicinity of the evaporator 320 through the return air outlet 114, and after being cooled by the evaporator 320, it is blown into the accommodating cavity 211 again through the first air outlet 112 and the second air outlet 113, and the cycle is repeated.

[0084] Since the horizontal freezer 10 provided in the embodiment of the present application mainly plays a cooling role, that is, the air blown out from the air duct module 100 is cold air, and according to the characteristics of the cold air itself, it will flow downward according to its own gravity. Under normal circumstances, in order to enable the cold air to circulate in the accommodating cavity 211, the first air outlet 112 will be arranged near the top of the cabinet body 200, the second air outlet 113 will be roughly located in the middle of the cabinet body, and the return air outlet 114 will be arranged near the bottom of the cabinet body 200, that is, the first air outlet 112 will be arranged above the second air outlet 113, and the second air outlet 113 will be arranged above the return air outlet 114.

[0085] In some embodiments, the cabinet 200 has a receiving cavity 211 , the receiving cavity 211 has a bottom surface 213 and a stepped surface 214 higher than the bottom surface 213 , and the air duct module 110 is installed on the stepped surface 214 .

[0086] Because the air duct module 110 is mounted on the stepped surface 214 and the return air vent 114 is disposed on the housing 110, the return air vent 114 is also located on the stepped surface 214. The return air vent 114 is located on the stepped surface 214, and the height of the stepped surface 214 is higher than the bottom surface 213 of the accommodating chamber 211, so that the return air vent 114 and the bottom surface 213 of the accommodating chamber 211 are at a certain height. When users stack items, the return air vent 114, which has a certain height, is less likely to be blocked, thereby allowing the air in the accommodating chamber 211 to circulate, thereby improving the cooling effect of the entire horizontal freezer 10.

[0087] Among them, the return air outlet 114 is located on the step surface 214, which does not mean that the return air outlet 114 is provided on the step surface 214, but means that the position of the return air outlet 114 is on the step surface 214, that is, the return air outlet 114 can be provided above the step surface 214, or one side can be against the step surface 214.

[0088] In some embodiments, the chest freezer 10 further includes a refrigeration element 330, which is disposed around the outer wall of the inner liner 221 and at least in the area between the stepped surface 214 and the bottom surface 213. The refrigeration element 330 is connected in series or in parallel with the evaporator 320. Because the return air vent 114 is disposed on the stepped surface 214, the area between the stepped surface 214 and the bottom surface 213 may not receive cold air. The refrigeration element 330 is disposed in the area between the stepped surface 214 and the bottom surface 213, allowing the area to be cooled by the refrigeration element 330, thereby ensuring a cooling effect for the entire chest freezer 10.

[0089] The refrigeration element 330 is at least arranged in the area between the step surface 214 and the bottom surface 213, which means that the refrigeration element 330 can be arranged only between the step surface 214 and the bottom surface 213, or can be arranged between the step surface 214 and the bottom surface 213 and above the step surface 214 at the same time.

[0090] The refrigeration component 330 may be a refrigeration coil or a patch evaporator.

[0091] In some embodiments, along the height direction Z of the cabinet 200 , the second air outlet 113 is located at 3 / 5 to 4 / 5 of the cabinet 200 .

[0092] Among them, the second air outlet 113 is set at 3 / 5 to 4 / 5 of the cabinet body 200, that is, in the height direction Z of the cabinet body 200 and from bottom to top, the second air outlet 113 is roughly located at 0.6 to 0.8 of the cabinet body 200, so that the second air outlet 113 is roughly located in the middle area of the horizontal freezer 10 in the height direction Z, so that the horizontal freezer 10 can directly blow towards the items in the accommodating cavity 211, and can freeze the items in the area close to the air duct module 100, thereby improving the refrigeration effect.

[0093] In some embodiments, along the height direction Z of the cabinet 200, the return air vent 114 is located at 1 / 4 to 1 / 2 of the cabinet 200. This means that in the vertical direction and from bottom to top, the return air vent 114 is located in the 1 / 4 to 1 / 2 area of the cabinet 200, that is, the return air vent 114 is roughly located in the lower area of the entire cabinet 200 but is still a certain distance away from the bottom surface 213 of the accommodating cavity 211. This allows the return air vent 114 to be located near the bottom area of the accommodating cavity 211, reducing the risk of blockage of the return air vent 114. This allows the cold air to flow to the bottom of the accommodating cavity 211 as much as possible, allowing the cold air to penetrate the entire internal space of the accommodating cavity 211 as much as possible, thereby improving the freezing effect.

[0094] The second shell section 121b and the third shell section 121c are used to form a fixed cavity 125 with the cabinet body 200 for mounting the evaporator 320. The evaporator 320 is fixed in the fixed cavity 125 formed by the second shell section 121b, the third shell section 121c, and the cabinet body 200, which facilitates the assembly of the air duct module 100 and the evaporator 320. During assembly, the air duct module 100 is first assembled into a whole, the evaporator 320 is mounted in a set position in the accommodating cavity 211, and then the entire air duct module 100 is assembled into the accommodating cavity 211. The second shell section 121b and the third shell section 121c are then mounted on the evaporator 320, forming a closed fixed cavity 125 with the main body 220. This allows air in the accommodating cavity 211 to enter the fixed cavity 125 through the return air port 114, be cooled by the evaporator 320, and then flow to the first air outlet 112.
