[0036] A freezer is a professional storage tool for storing various items that need to be frozen, which can keep food or other items in a frozen state, and is divided into household and commercial types. The refrigeration system of the freezer consists of components such as a compressor, a condenser, a capillary tube, and an evaporator. Through the continuous circulation of the refrigerant, the heat inside the freezer is brought outside the freezer to achieve the purpose of cooling.

[0037] In order to reduce the problem of condensation inside the freezer, the air-cooling method can be used for refrigeration. The cold air is circulated by a fan to ensure that the food and beverages can maintain a roughly consistent temperature throughout the freezer. However, in the related art, the cold air method of the air duct module of the freezer is prone to a large temperature difference inside the freezer, resulting in poor refrigeration effect. The air duct module and the horizontal freezer provided by the embodiments of the present application can improve the above problems. The air duct module and the horizontal freezer provided by the embodiments of the present application can enable the cold air to flow at different heights inside the horizontal freezer and can cover different areas of the horizontal freezer as much as possible, thereby improving the freezing effect.

[0038] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0039] Please refer to Figure 1 and Figure 2, Embodiment of the present application provides an air duct module 100, which is mainly applied to refrigeration equipment. The air duct module 100 provided by the embodiment of the present application enables cold air to flow at different heights in the horizontal freezer 10, and can cover different areas of the horizontal freezer 10 as much as possible, thereby improving the freezing effect.

[0040] Among them, the refrigeration equipment can be a refrigerator or a freezer. Specifically, the freezer can be a horizontal freezer 10 or a vertical freezer. In the embodiment of the present application, for the convenience of description, it is taken as an example that the refrigeration equipment is a horizontal freezer 10. When the refrigeration equipment is other equipment, it can be analogized accordingly.

[0041] The horizontal freezer 10 is generally a cuboid. For the convenience of description, the height direction Z, width direction X, and thickness direction Y are respectively defined. Among them, in the use state of the horizontal freezer 10, the vertical direction is the height direction Z, and the projection of the horizontal freezer 10 in the vertical direction is a rectangle. The direction where the long side is located is the width direction X, and the direction where the wide side is located is the thickness direction Y.

[0042] Since the thickness of the air duct module 100 is relatively small compared to the width, and the width of the air duct module 100 is basically equal to the thickness of the horizontal freezer 10, the air duct module 100 can be installed on one 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. The air blown out of the freezer can cover the inside of the entire cabinet 200200, and the freezing uniformity can be improved as much as possible.

[0043] Similarly, for the convenience of description, six directions including up, down, left, right, front, and back are defined. Among them, in the height direction Z, the side close to the opening is up, and the side close to the bottom surface 213 is down. In the width direction X, the two directions are respectively left and right, and the installation position of the air duct module 100 is right, and the opposite side is left. In the thickness direction Y, the connection between the door body 230 and the main body 220 is the back, and the opposite side is the front.

[0044] In the embodiment of the present application, the air duct module 100 includes a housing 120 and a flow guiding member 130. The housing 120 has an installation cavity 124, a first air outlet 112 communicating with the installation cavity 124, and a return air opening 114; the flow guiding member 130 is installed in the installation cavity 124, and can enable external gas to enter the installation cavity 124 through the return air opening 114, and the gas in the installation cavity 124 flows out of the installation cavity 124 from the first air outlet 112.

[0045] Among them, the air outlet area of the first air outlet 112 is arc-shaped.

[0046] The air duct module 100 is applied to a refrigeration device (horizontal freezer 10) and is installed inside the cabinet body 200 of the refrigeration device (horizontal freezer 10). It can make the air inside the refrigeration device (horizontal freezer 10) flow, so that the air inside the refrigeration device (horizontal freezer 10) can be blown to the frozen items after being cooled by the evaporator 320. That is to say, it can be considered that the air duct module 100 is mainly used to blow cold air into the refrigeration device (horizontal freezer 10), so that the cold air can circulate inside the refrigeration device (horizontal freezer 10), and as much as possible to ensure that the temperature in the same chamber of the refrigeration device (horizontal freezer 10) is approximately the same, reducing the temperature difference in the same chamber.

[0047] The housing 120 is the basic component of the air duct module 100 and can provide an installation basis for other structures of the air duct module 100. Structures such as the flow guiding member 130 can be installed on the housing 120, so that the air duct module 100 can form a whole, which is convenient for the installation and transportation of the air duct module 100. At the same time, the housing 120 can also protect structures such as the flow guiding member 130 and reduce the damage to the flow guiding member 130 and the like by external structures.

[0048] The flow guiding member 130 is mainly used for disturbing the flow, so that the air can circulate in the refrigeration device, that is, the air inside the refrigeration device can continuously flow to the evaporator 320, and after being cooled by the evaporator 320, it is blown to the frozen items again.

[0049] The air outlet area of the first air outlet 112 being arc-shaped means that the air outlet area in the height direction Z of the horizontal freezer 10 is arc-shaped. The air outlet area in the height direction Z is arc-shaped, so that the cold air blown out from the first air outlet 112 can have multiple different directions in the height direction Z. Furthermore, the cold air blown out from the first air outlet 112 can be blown to different heights inside the horizontal freezer 10, so that the cold air can flow at different heights inside the horizontal freezer 10, and as much as possible can cover different areas of the horizontal freezer 10, thereby improving the freezing effect.

[0050] In addition, since the air duct module 100 is applied to the horizontal freezer 10, the air outlet area of the first air outlet 112 is arc-shaped in the height direction Z of the horizontal freezer 10, that is, the air outlet area of the first air outlet 112 is arc-shaped in the vertical plane.

[0051] Among them, the air outlet area of the first air outlet 112 being arc-shaped can be that the shape of the first air outlet 112 is arc-shaped, or a sweeping member can be provided at the first air outlet 112 to form an arc-shaped air outlet area through the sweeping of the sweeping member.

[0052] In some embodiments, the air duct module 100 is installed on one side of the horizontal freezer 10 in the width direction X. After the air duct module 100 is disposed within the horizontal freezer 10, the first air outlet 112 is located above the air return opening 114. The air outlet area of the first air outlet 112 is arc-shaped, such that the cold air blown out from the first air outlet 112 has an upward flow tendency. After the upward cold air is guided by the door body 230 of the horizontal door body 230, it can flow to the other side of the accommodation cavity 211 in the width direction X, so that the side of the accommodation cavity 211 away from the air duct module 100 can be blown by the cold air, thereby improving the uniformity of the cold air in the accommodation cavity 211 as much as possible, and further improving the refrigeration effect as much as possible.

[0053] Since the air outlet direction of the first air outlet 112 is arc-shaped, while having an upward air outlet direction, it also has a leftward air outlet direction, that is, the first air outlet 112 also has a substantially horizontal air outlet direction, such that the cold air blown out from the first air outlet 112 can directly blow into the area around the air duct module 100. Furthermore, the first air outlet 112 can discharge air at different levels and freeze items at different positions.

[0054] Please refer to Figure 3 and Figure 4 In some embodiments, at least a part of the first air outlet 112 is arc-shaped. The first air outlet 112 is located at the top of the housing 120. That at least a part of the first air outlet 112 is arc-shaped may mean that the entire first air outlet 112 is arc-shaped, or a part of the first air outlet 112 is arc-shaped and the other part is linear. Specifically, it may not be limited.

[0055] The first air outlet 112 is located at the top of the housing 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 also located at the top of the housing 120, the cold air blown out from the first air outlet 112 can blow upward and leftward, such that the upward cold air can flow to the left side of the cabinet body 200 after being guided by the door body 230, and the leftward cold air can directly blow into the area near the air duct module 100. Furthermore, the cold air can flow as much as possible within the entire cabinet body 200, improving the refrigeration effect.

[0056] In some embodiments, the radian of the first air outlet 112 is 80 degrees to 100 degrees. The radian of the first air outlet 112 refers to the radian in the vertical plane. Specifically, the radian of the first air outlet 112 can be 80 degrees, 82 degrees, 85 degrees, 90 degrees, 95 degrees, etc.

[0057] The radian of the first air outlet 112 is 80 degrees to 100 degrees, so that the first air outlet 112 can cover as much as possible the upper part and the left side of the air duct module 100, so that the first air outlet 112 can have an upward vertical air outlet direction at the top of the housing 120 and a horizontal upper left air outlet direction at the side of the housing 120, and at the same time, there are also multiple inclined upward and leftward air outlet directions between the vertical upward and the horizontal leftward, 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, improving the refrigeration effect.

[0058] 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 surface 126a and the second surface 126b, and the first air outlet 112 are respectively located on the first surface 126a and the second surface 126b.

[0059] Among them, the first surface 126a is located at the top of the housing 120, the second surface 126b is located at the side of the housing 120, and the first air outlet 112 extends from the first surface 126a to the second surface 126b, so that a part of the first air outlet 112 is located at the top of the housing 120, a part is located at the side of the housing 120, and the intermediate transition region is connected by an arc transition, so that the entire first air outlet 112 is arc-shaped.

[0060] In some embodiments, there are multiple first air outlets 112. The multiple first air outlets 112 are located at the same height of the air duct module 100, and 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 radian of the multiple first air outlets 112 can be the same or different, and can be set according to the actual situation.

[0061] The multiple first air outlets 112 are sequentially spaced apart in the thickness direction Y, so that the first air outlets 112 are arranged as much 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 as much as possible the plane formed by the width direction X and the thickness direction Y, improving the coverage area of the cold air, and thus improving the refrigeration effect.

[0062] In some embodiments, the first air outlet 112 is provided with an air outlet grille 112a. Since the first air outlet 112 is arc-shaped and has an upwardly disposed portion, in order to ensure the amount of cold air from the first air outlet 112, the opening area of the first air outlet 112 will not be set particularly small. Also, since the first air outlet 112 is disposed at the top of the cabinet 200, it is easy for some small-volume items to enter the interior of the housing 120 from the first air outlet 112 during the process of the user taking or placing items. The air outlet grille 112a is provided on the first air outlet 112 to reduce the opening area of a single hole of the first air outlet 112, thereby reducing the risk of small-volume items entering the housing 120 from the first air outlet 112.

[0063] In some embodiments, the air outlet grille 112a is injection-molded and connected to the housing 120. The air outlet grille 112a can be directly integrally formed with the housing 120 by injection molding, so that the air outlet grille 112a and the housing 120 form a whole, which can reduce the risk of the air outlet grille 112a falling off the housing 120, reduce the risk of the air outlet grille 112a falling into the housing 120, reduce the failure rate of the air duct module 100, and increase the service life of the air duct module 100.

[0064] In some embodiments, the air outlet grille 112a has a plurality of mesh holes 112b, the plurality of mesh holes 112b are arranged at intervals, and the maximum width of each mesh hole 112b is less than or equal to 1.5 mm.

[0065] The width of the mesh 112b may be the distance between any two points on the mesh 112b, and the maximum width is the distance between the two points in the mesh 112b that are the farthest apart. Since the length of a rice grain is approximately 1.5 mm, the maximum width of the mesh 112b is less than or equal to 1.5 mm, so as to prevent rice grains or objects of the same volume level as rice grains from entering the housing 120 as much as possible, thereby reducing the failure rate of the air duct module 100 and increasing the service life of the air duct module 100.

[0066] In some embodiments, the air outlet grille 112 a is disposed at least in an upper region of the first air outlet 112 .

[0067] The upper area of the first air outlet 112 refers to the area where the air outlet direction has an upward component, that is, the air outlet direction in the area can be vertically upward, can be inclined upward, or can be partially vertically upward and partially inclined upward. The upper area of the first air outlet 112 is arranged toward the door body 230. After the door body 230 is opened, impurities are most likely to enter the housing 120 through the upper area. The air outlet grille 112a is arranged in the upper area to minimize the risk of impurities entering the housing 120.

[0068] The air outlet grille 112a is disposed at least in the upper region of the first air outlet 112. It may be only disposed in the upper region of the first air outlet 112, or may be disposed in the upper region of the first air outlet 112 and in other regions of the first air outlet 112 except the upper region.

[0069] In some embodiments, the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 includes a first housing section 121a, a second housing section 121b, and a third housing section 121c. The second housing section 121b connects the first housing section 121a and the third housing section 121c respectively. The rear housing 123 is connected to the first housing section 121a to form an installation cavity 124. The second housing section 121b and the third housing section 121c are used to form a fixing cavity 125 for installing the evaporator 320 with the cabinet 200. Among them, the first air outlet 112 is disposed on the first housing section 121a, and the air return opening 114 is disposed on the third housing section 121c.

[0070] Please refer to Figure 1 and Figure 2 , the housing 120 includes a front housing 121 and a rear housing 123. The front housing 121 and the rear housing 123 are connected. The front housing 121 further includes a first housing section 121a, a second housing section 121b, and a third housing section 121c. The first housing section 121a is located above the second housing section 121b, and the second housing section 121b is located above the third housing section 121c. The first housing section 121a and the rear housing 123 form an installation cavity 124 for accommodating the drainage member 130. An air inlet 115 is provided on the rear housing 123, and the air return opening 114 is disposed on the third housing section 121c and communicates with the fixing cavity 125.

[0071] Among them, when the air in the accommodation cavity 211 enters the fixing cavity 125 through the air return opening 114, under the action of the drainage member 130, it will flow towards the air inlet 115, so that the air entering the fixing cavity 125 will flow through the evaporator 320 for refrigeration and then flow into the installation cavity 124, and then be blown into the accommodation cavity 211 through the first air outlet 112. That is to say, the evaporator 320 is disposed between the air return opening 114 and the air inlet 115 and refrigerates during the process of air circulation, so that the air blown out from the first air outlet 112 is always cold air, improving the refrigeration effect.

[0072] It should be noted that the evaporator 320 is fixed in the fixing cavity 125 jointly formed by the second housing section 121b, the third housing section 121c and the cabinet body 200, which facilitates the assembly of the air duct module 100 and the evaporator 320. During assembly, first assemble the air duct module 100 into a whole, assemble the evaporator 320 at the set position of the accommodating cavity 211, and then assemble the whole of the air duct module 100 into the accommodating cavity 211, so that the second housing section 121b and the third housing section 121c cover the evaporator 320 and form a closed fixing cavity 125 with the main body 220, so that the air in the accommodating cavity 211 can enter the fixing cavity 125 through the return air outlet 114, be cooled by the evaporator 320 and then flow to the first air outlet 112.

[0073] In some embodiments, the third housing section 121c protrudes from the second housing section 121b, and the return air outlet 114 is arranged at one end of the third housing section 121c away from the second housing section 121b.

[0074] The fact that the third housing section 121c protrudes from the second housing section 121b means that the third housing 120 protrudes from the second housing section 121b in the width direction X. That is, in the width direction X, the third housing section 121c is arranged to the left of the second housing section 121b, and the third housing section 121c is closer to the central area of the accommodating cavity 211. The return air outlet 114 is arranged at one end of the third housing section 121c away from the second housing section 121b and the first air outlet 112 is arranged on the first housing section 121a. It can be considered that in the width direction X, among the return air outlet 114 and the first air outlet 112, the return air outlet 114 is arranged closer to the central area of the accommodating cavity 211, so that the gas in the accommodating cavity 211 can more easily enter the fixing cavity 125 through the return air outlet 114, so that the gas can stay and grow in the fixing cavity 125, thereby increasing the heat exchange time with the evaporator 320, improving the refrigeration effect on the air, and further improving the freezing effect.

[0075] Please refer to Figure 5 and Figure 6 , based on the same inventive concept, the embodiment of the present application also provides a horizontal freezer 10, which includes a cabinet body 200 and an air duct module 100, and the cabinet body 200 has an accommodating cavity 211 for accommodating the air duct module 100.

[0076] 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, which can provide an installation foundation for structures such as the air duct module 100, the compressor 310, the evaporator 320, and the condenser, and can also play a role in protecting the above-mentioned electronic components.

[0077] Among them, the cabinet body 200 includes a main body 220 and a door body 230 connected to the main body 220. The door body 230 covers the opening of the main body 220. The accommodation cavity 211 is arranged inside the main body 220, and the items to be refrigerated are arranged in the accommodation cavity 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 foaming layer. There is an electrical cavity 215 for accommodating the compressor 310 between the inner liner 221 and the outer shell 223, and the electrical control box is also arranged in the electrical cavity 215.

[0078] The evaporator 330 can be a fin evaporator or a patch evaporator.

[0079] The air duct module 100 is arranged in the accommodation cavity 211, and both the first air outlet 112 and the air return port 114 communicate with the accommodation cavity 211. The air duct module 100 blows the cold air cooled by the evaporator 320 from the first air outlet 112 into the accommodation cavity 211. The gas in the accommodation cavity 211 can return to the vicinity of the evaporator 320 through the air return port 114, and after being cooled by the evaporator 320, it is blown into the accommodation cavity 211 again through the first air outlet 112, and so on in a cycle.

[0080] Since the horizontal freezer 10 provided by the embodiment of the present application mainly plays a refrigeration 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, it will flow downward according to its own gravity. Generally, in order to enable the cold air to circulate in the accommodation cavity 211, the first air outlet 112 is arranged near the top of the cabinet body 200, and the air return port 114 is arranged near the bottom of the cabinet body 200, that is, the first air outlet 112 is arranged above the air return port 114.

[0081] In some embodiments, the horizontal freezer 10 further includes a compressor 310, and the cabinet body 200 further has an electrical cavity 215, and the compressor 310 is installed in the electrical cavity 215.

[0082] The compressor 310 is an essential component in the refrigeration system of the horizontal freezer 10. A cavity for accommodating the compressor 310 needs to be arranged in the cabinet body 200. The electrical cavity 215 and the accommodation cavity 211 are independent cavities. The cabinet body 200 includes an inner liner 221 and an outer shell 223. The accommodation cavity 211 is arranged inside the inner liner 221, and the electrical cavity 215 is arranged between the inner liner 221 and the outer shell 223.

[0083] Since the overall appearance of the entire cabinet body 200 is generally a cuboid, after the electrical cavity 215 is provided between the inner liner 221 and the outer shell 223, the inner liner 221 is not a regular cuboid, that is, a stepped surface 214 will be formed above the electrical cavity 215. By setting the air return opening 114 at this position, the existing structure of the horizontal freezer 10 can be utilized, and there is no need to separately set a stepped surface 214 higher than the bottom surface 213 in the accommodation cavity 211. This can not only improve the problem of blockage of the air return opening 114, but also reduce the number of components in the horizontal freezer 10 and reduce the occupation of the volume of the accommodation cavity 211.

[0084] In some embodiments, the cabinet body 200 has a thickness direction Y and a width direction X. The length of the cabinet body 200 in the width direction X is greater than the length in the thickness direction Y, and the air return opening 114 is arranged facing the width direction X.

[0085] Among them, the entire air duct module 100 is installed on the right side of the accommodation cavity 211. The air return opening 114 being arranged facing the width direction X makes the air return direction roughly along the entire width direction X, so that the cold air can flow and circulate roughly within the entire cabinet body 200, improving the freezing effect.

[0086] In some embodiments, along the height direction Z of the cabinet body 200, the air return opening 114 is located at the 1 / 4 - 1 / 2 position of the cabinet body 200. This means that in the vertical direction and from bottom to top, the air return opening 114 is located within the 1 / 4 - 1 / 2 area of the cabinet body 200, that is, the air return opening 114 is roughly located in the lower area of the entire cabinet body 200 but there is still a certain distance from the bottom surface 213 of the accommodation cavity 211. This enables the air return opening 114 to be in the area close to the bottom of the accommodation cavity 211. While reducing the risk of blockage of the air return opening 114, it can make the cold air flow to the bottom of the accommodation cavity 211 as much as possible, enabling the cold air to penetrate the internal space of the entire accommodation cavity 211 as much as possible, and thus improving the freezing effect.

[0087] In some embodiments, the housing 120 is further provided with a second air outlet 113 communicating with the installation cavity 124. The first air outlet 112 is located above the second air outlet 113, and the second air outlet 113 is located above the air return opening 114.

[0088] Among them, the first air outlet 112, the second air outlet 113, and the air return opening 114 are arranged from high to low in sequence. The first air outlet 112 is close to the top of the accommodation cavity 211, the air return opening 114 is close to the bottom of the accommodation cavity 211, and the second air outlet 113 is roughly arranged in the middle area of the accommodation cavity 211, enabling the cold air to form multiple different circulation areas and improving the refrigeration effect.

[0089] Specifically, when the user is placing items, they basically stack them from bottom to top. There are more items at the bottom and more cooling capacity is required. By setting the second air outlet 113 between the first air outlet 112 and the return air outlet 114, the cold air can roughly blow out from the middle area of the cabinet body 200 and can quickly blow to the bottom area of the accommodation cavity 211. Through the cooperation of the first air outlet 112 and the second air outlet 113, the cold air can be more evenly blown to different areas in the accommodation cavity 211, thereby making the refrigeration effect better.

[0090] The air duct module 100 is arranged on one side in the width direction X of the accommodation cavity 211, and the first air outlet 112 is roughly arranged at the top of the accommodation cavity 211, and the second air outlet 113 is roughly arranged in the middle of the accommodation cavity 211. Since there is less possibility of placing items at the top of the accommodation cavity 211, the cold air blown out from the first air outlet 112 can be blown to the other side in the width direction X in the accommodation cavity 211 as much as possible, so that the area far from the air duct module 100 can be blown by the cold air. The second air outlet 113 is roughly arranged in the middle area of the accommodation cavity 211, so that the cold air blown out from the second air outlet 113 can directly blow on the items near the air duct module 100, and thus the items in the accommodation cavity 211 can be blown by the cold air as much as possible, thereby improving the refrigeration effect of the entire horizontal freezer 10.

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

[0092] Among them, the second air outlet 113 is arranged at 3 / 5 to 4 / 5 of the cabinet body 200, that is, in the height direction Z of the cabinet body 200 and in the upward direction from the bottom, 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 on the items in the accommodation cavity 211 and can freeze the items in the area near the air duct module 100, improving the refrigeration effect.

[0093] In some embodiments, the horizontal freezer 10 further includes a refrigeration component 330, and the refrigeration component 330 is wound around the outer side wall of the inner container 221 (the refrigeration component 330 is arranged between the inner container 221 and the outer shell 223), and at least wound around the area between the step surface 214 and the bottom surface 213. The refrigeration component 330 is connected in series or in parallel with the evaporator 320. Since the return air outlet 114 is arranged on the step surface 214, there may be a situation where the area between the step surface 214 and the bottom surface 213 cannot be blown by the cold air. By arranging the refrigeration component 330 in the area between the step surface 214 and the bottom surface 213, this area can be refrigerated by the refrigeration component 330, thereby ensuring the refrigeration effect of the entire horizontal freezer 10.

[0094] The refrigerating member 330 is at least wound around the area between the stepped surface 214 and the bottom surface 213, which means that the refrigerating member 330 can be only wound around the area between the stepped surface 214 and the bottom surface 213, or can be wound around the area between the stepped surface 214 and the bottom surface 213 and be disposed above the stepped surface 214 at the same time.

[0095] The refrigerating member 330 can be a refrigerating coil or a patch evaporator.
