[0035] 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 parts 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.

[0036] In order to reduce the problem of condensation inside the freezer, the air-cooled method can be used for refrigeration. The cold air is circulated by a fan to ensure that 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.

[0037] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0038] Please refer to Figures 1 - 6 , the embodiments of the present application provide an air duct module 100. The air duct module 100 provided by the embodiments of the present application is mainly applied to refrigeration equipment. The air duct module 100 provided by the embodiments of the present application can enable the cold air to flow at different heights inside the horizontal freezer 10 and can cover different areas of the horizontal freezer 10 as much as possible, thereby improving the freezing effect.

[0039] Among them, the refrigeration device can be a refrigerator or a freezer. Specifically, the freezer can be a horizontal freezer 10 or a vertical freezer. In the embodiments of the present application, for the convenience of description, it is exemplified that the refrigeration device is a horizontal freezer 10. When the refrigeration device is other devices, it can be analogized accordingly.

[0040] The horizontal freezer 10 is generally a cuboid. For the convenience of description, the height direction Z, the width direction X, and the thickness direction Y are respectively defined. Among them, in the usage 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.

[0041] 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 surface 121 in the width direction X of the horizontal freezer 10, so that the air blown out of the freezer can cover the side surface 121 formed by the height direction Z and the width direction X as much as possible. Make the air blown out of the freezer cover the inside of the entire cabinet body 200, and improve the freezing uniformity as much as possible.

[0042] Similarly, for the convenience of description, six directions such as up, down, left, right, front, and back are defined. Among them, in the height direction Z, the side close to the opening 221 is up, and the side close to the bottom surface is down. In the width direction X, the two directions are respectively left and right. The installation position of the air duct module 100 is right, and the opposite side is left. In the thickness direction Y, the connection part between the door body 230 and the main body 220 is the back, and the opposite side is the front.

[0043] In the embodiments of the present application, please refer to Figures 1 - 3 , the air duct module 100 includes a housing 120, a diversion member 130, and a wind guiding member 115. The housing 120 has an installation cavity 124, a first air outlet 112 communicating with the installation cavity 124, and a return air port 114. The diversion member 130 is installed in the installation cavity 124, and the wind guiding member 115 is arranged at the first air outlet 112.

[0044] Among them, the housing 120 has a top surface 122 and a side surface 121 arranged at an angle with the top surface 122, and the first air outlet 112 is arranged on the top surface 122 and the side surface 121.

[0045] The air duct module 100 is applied to a refrigeration device (horizontal freezer 10) and is installed inside the cabinet 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 towards the frozen items after being cooled by the evaporator. That is, 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 roughly the same, and reduce the temperature difference in the same chamber.

[0046] 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 play a protective role for structures such as the flow guiding member 130 and can reduce the damage to the flow guiding member 130 and the like by external structures.

[0047] 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, and after being cooled by the evaporator, it is blown towards the frozen items again. That is, the flow guiding member 130 can make the external gas enter the installation cavity 124 through the return air outlet 114, and the gas in the installation cavity 124 flows out of the installation cavity 124 from the first air outlet 112.

[0048] Among them, the flow guiding member 130 can be a fan. Specifically, it can be a centrifugal fan, an axial flow fan, or a cross-flow fan.

[0049] The flow guiding part is used to guide the cold air blown out from the first air outlet 112, so that the cold air can be blown out at a specific angle. The cold air can be blown out at a specific angle, or can be blown out at multiple different angles, so that the cold air can cover different areas of the horizontal freezer 10 as much as possible. The flow guiding part can cover all the first air outlets 112, so that the cold air blown out from the first air outlets 112 can be blown out at a specific angle. The flow guiding part can also cover part of the first air outlets 112, so that part of the cold air blown out from the first air outlets 112 is blown out at a specific angle. There is no limit to this.

[0050] The side surface 121 of the housing 120 is parallel to the side surface 121 in the width direction X of the horizontal freezer 10, and the top surface 122 of the housing 120 and the side surface 121 are arranged at an angle in the height direction Z. The first air outlet 112 is arranged on the top surface 122 and the side surface 121. That is, the cold air from the first air outlet 112 can blow out from the top surface 122 (upward) and can also blow out from the side surface 121 (leftward), so that the cold air blown out from the first air outlet 112 can have different directions in the height direction. Furthermore, the cold air blown out from the first air outlet 112 can blow to different heights inside the horizontal freezer 10, so that the cold air can flow at different heights inside the horizontal freezer 10 and can cover different areas of the horizontal freezer 10 as much as possible, thereby improving the freezing effect.

[0051] Moreover, under the action of the flow guiding member, the cold air can also blow out at one or more angles on the side surface 121 or the top surface 122 respectively. That is, the cold air can not only blow out from the top surface 122 and the side surface 121 simultaneously, but also the cold air can blow out at one or more angles on the side surface 121 and can also blow out at one or more angles on the top surface 122, thereby further increasing the blowing directions of the cold air in the height direction and improving the refrigeration effect.

[0052] Please refer to Figure 3 , in some embodiments, the first air outlet 112 includes a first air outlet section 112b, a second air outlet section 112c and a third air outlet section 112d. The first air outlet section 112b is arranged on the top surface 122, the third air outlet section 112d is arranged on the side surface 121, the second air outlet section 112c is arranged at the connection of the top surface 122 and the side surface 121, and the air guiding member 115 is at least arranged on the third air outlet section 112d.

[0053] Since the first air outlet section 112b is arranged on the top surface 122 and the third air outlet section 112d is arranged on the side surface 121, the cold air blown out from the first air outlet section 112b flows upward, and the cold air blown out from the third air outlet section 112d flows to the left. That is, the cold air blown out from the first air outlet section 112b mainly covers the upper region of the horizontal freezer 10, while the middle and lower regions of the horizontal freezer 10 need to be mainly covered by the cold air blown out from the third air outlet section 112d. Obviously, since the third air outlet section 112d is connected to the first air outlet section 112b located on the top surface 122, the third air outlet section 112d is also located in the upper part of the side surface 121. Therefore, the air guiding member 115 needs to be at least arranged on the third air outlet section 112d, so that the cold air blown out from the third air outlet section 112d can be adjusted in angle through the drainage of the air guiding member 115 to cover the middle and lower regions of the horizontal freezer 10 as much as possible.

[0054] Specifically, when a user places frozen items, they generally place them at the bottom first, and there will be more frozen items piled up at the bottom. Therefore, the cold air demand at the bottom is relatively large. Thus, the air guiding member 115 can divert the cold air blown out by the third air outlet section 112d downward, so that most of the cold air can be blown downward to meet the cold air demand at the bottom.

[0055] Please refer to Figure 3 , in some embodiments, at least the second air outlet section 112c is arc-shaped. That is, it can be that only the second air outlet section 112c is arc-shaped, and the first air outlet section 112b and the third air outlet section 112d are linear, or it can be that the first air outlet section 112b, the second air outlet section 112c, and the third air outlet section 112d are all arc-shaped.

[0056] Since the second air outlet section 112c is arc-shaped, and the second air outlet section 112c connects the first air outlet section 112b and the second air outlet section 112c, the entire first air outlet 112 can be made 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 housing 120, the cold air blown out by the first air outlet 112 can be blown upward and to the left, so 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 cold air blown to the left can directly blow into the area near the air duct module 100. Thus, the cold air can flow as much as possible inside the entire cabinet body 200, improving the refrigeration effect.

[0057] Please refer to Figure 3 , in some embodiments, the air guiding member 115 includes a plurality of air guiding plates 115a, and the plurality of air guiding plates 115a are arranged at intervals on the third air outlet section 112d, and the air guiding plates 115a are inclined.

[0058] The plurality of air guiding plates 115a are arranged at intervals in the height direction Z. A channel is formed between two adjacent air guiding plates 115a. The cold air blown out by the third air outlet section 112d flows out through the channel, and the air guiding plates 115a can guide the cold air blown out by the third air outlet section 112d, so that the cold air is blown out at one or more specific angles. The setting angle of the air guiding plates 115a is the blowing angle of the cold air. Since the air guiding plates 115a are inclined, the cold air can flow out along the inclined direction, so that the coverage range of the cold air is larger, improving the freezing effect.

[0059] In some embodiments, the air guiding plates 115a are inclined upward by 0 to 80° or inclined downward by 0 to 80°.

[0060] The air deflector 115a can be tilted upward or downward according to actual needs. When more cooling capacity is required in the middle or upper part of the horizontal freezer 10, the air deflector 115a is tilted upward, and the cold air blown out by the third air outlet section 112d will flow upward along the air deflector 115a. When more cooling capacity is required in the middle or lower part of the horizontal freezer 10, the air deflector 115a is tilted downward, and the cold air blown out by the third air outlet section 112d will flow downward along the air deflector 115a.

[0061] Specifically, the tilt angle of the air deflector 115a can be 20°, 30°, 40°, 50°, 60°, etc.

[0062] In some embodiments, along the vertical direction, the tilt angles of the plurality of air deflectors 115a gradually decrease or gradually increase.

[0063] That is, in the height direction Z, the tilt angles of the plurality of air deflectors 115a gradually decrease or gradually increase. That is to say, the tilt angles of the plurality of air deflectors 115a are not the same, and the angle change shows a gradual change trend. In this way, the different directions of the cold air blown out from the first air outlet 112 in the height direction Z can be further increased, so that the cold air blown out from the first air outlet 112 can further cover different areas of the horizontal freezer 10 to improve the freezing effect.

[0064] Please refer to Figure 3 , in some embodiments, the air guiding member 115 includes a plurality of air deflectors 115a, and the plurality of air deflectors 115a are arranged at intervals in the first air outlet 112, and the air deflectors 115a are inclined.

[0065] The plurality of air deflectors 115a being arranged at intervals in the first air outlet 112 means that the plurality of air deflectors 115a can be arranged in all of the first air outlet 112, so that the cold air blown out by the first air outlet section 112b, the second air outlet section 112c and the third air outlet section 112d can all adjust the angle through the diversion of the air deflectors 115a, thereby further increasing the different directions of the cold air blown out from the first air outlet 112 in the height direction Z.

[0066] The plurality of air deflectors 115a are arranged at intervals in the height direction Z, and a channel is formed between two adjacent air deflectors 115a. The cold air blown out from the first air outlet 112 flows out through the channel, and the air deflector 115a can guide the cold air blown out from the first air outlet 112, so that the cold air is blown out at one or more specific angles. The set angle of the air deflector 115a is the blowing angle of the cold air. Since the air deflector 115a is inclined, the cold air can flow out along the inclined direction, so that the coverage range of the cold air is larger and the freezing effect is improved.

[0067] The air deflector 115a can be tilted upward by 0 to 80° or downward by 0 to 80°. When more cooling capacity is required in the middle or upper part of the horizontal freezer 10, the air deflector 115a is tilted upward, and the cold air blown out from the third air outlet section 112d will flow upward along the air deflector 115a. When more cooling capacity is required in the middle or lower part of the horizontal freezer 10, the air deflector 115a is tilted downward, and the cold air blown out from the third air outlet section 112d will flow downward along the air deflector 115a. Specifically, the tilt angle of the air deflector 115a can be 20°, 30°, 40°, 50°, 60°, etc.

[0068] In the vertical direction, the tilt angles of multiple air deflectors 115a can gradually decrease or gradually increase. That is, in the height direction Z, the tilt angles of multiple air deflectors 115a gradually decrease or gradually increase. That is to say, the tilt angles of multiple air deflectors 115a are not the same, and the angle change shows a gradual change trend. In this way, the different directions of the cold air blown out from the first air outlet 112 in the height direction Z can be further increased, and then the cold air blown out from the first air outlet 112 can further cover different areas of the horizontal freezer 10 to improve the freezing effect.

[0069] In some embodiments, an air outlet grille 112a is provided at the first air outlet 112. Since the first air outlet 112 is arc-shaped and has a part facing upward, in order to ensure the cold air volume of the first air outlet 112, the opening area of the first air outlet 112 is not set to be particularly small. Also, since the first air outlet 112 is provided at the top of the cabinet body 200, it is easy for some small items to enter the interior of the housing 120 from the first air outlet 112 during the process of users taking and placing things. Setting the air outlet grille 112a on the first air outlet 112 can reduce the opening area of a single hole of the first air outlet 112, and thus can reduce the risk of small items entering the housing 120 from the first air outlet 112.

[0070] Since multiple air deflectors 115a can be provided at the entire first air outlet 112, and the air outlet grille 112a also covers the entire first air outlet 112, the air outlet grille 112a can be used as an installation component for the air deflectors 115a, that is, multiple air deflectors 115a are all provided on the air outlet grille 112a.

[0071] Please refer to Figure 1 , in some embodiments, the air return opening 114 is inclined.

[0072] That is, along the height direction Z of the horizontal freezer 10, the air return opening 114 is inclined. The inclination direction of the air return opening 114 can be towards the bottom surface of the horizontal freezer 10 or towards the opening 221 of the horizontal freezer 10.

[0073] Since the air inside the horizontal freezer 10 needs to maintain a certain flow to ensure uniform distribution of cold air, if the area of the air return opening 114 is small, it may cause poor air flow and affect the cooling efficiency of the refrigerator. The air return opening 114 is inclined so that the air return opening 114 has a certain angle in the height direction Z. This can increase the area of the air return opening 114 while occupying the same space, making the air flow smoother and improving the cooling efficiency.

[0074] Based on the same inventive concept, please refer to Figures 4 - 6 , an embodiment of the present application further provides a horizontal freezer 10. The horizontal freezer 10 includes a cabinet body 200 and an air duct module 100. The cabinet body 200 has a receiving cavity for receiving the air duct module 100, and the air duct module 100 is installed in the receiving cavity. 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 basis for structures such as the air duct module 100, compressor, evaporator, condenser, etc., and can also play a role in protecting the above-mentioned electronic components.

[0075] 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 221 of the main body 220. The receiving cavity is provided in the main body 220, and the items to be refrigerated are arranged in the receiving cavity. The cold air blown out by the air duct module 100 is used to freeze the items.

[0076] In some embodiments, along the height direction Z of the cabinet body 200, the air return opening 114 is located at 1 / 4 to 1 / 2 of the cabinet body 200. This means that in the vertical direction, the air return opening 114 is located in the area of 1 / 4 to 1 / 2 of the cabinet body 200, that is, the air return opening 114 is generally 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 receiving cavity 211. This enables the air return opening 114 to be in the bottom area near the receiving 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 receiving cavity 211 as much as possible, so that the cold air can penetrate the internal space of the entire receiving cavity 211 as much as possible, thereby improving the freezing effect.

[0077] 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.

[0078] Among them, the first air outlet 112, the second air outlet 113, and the air return opening 114 are arranged in order from high to low. The first air outlet 112 is close to the top of the receiving cavity 211, the air return opening 114 is close to the bottom of the receiving cavity 211, and the second air outlet 113 is generally arranged in the middle area of the receiving cavity 211, so that the cold air can form multiple different circulation areas and improve the refrigeration effect.

[0079] Specifically, when the user places items, they basically stack them from bottom to top. There are more items at the bottom and more cooling capacity is required. Since the first air outlet 112 is located at the top of the housing 120, the coverage of the middle and bottom regions of the horizontal freezer 10 is limited. Therefore, in order to further ensure the cold air volume in the middle and bottom regions, a second air outlet 113 is provided between the first air outlet 112 and the air return port 114, so that the cold air can roughly blow out from the middle region of the cabinet body 200 and can quickly blow to the bottom region 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 blown more evenly to different regions in the accommodation cavity 211, thereby making the refrigeration effect better.

[0080] 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 as much as possible to the other side in the width direction X in the accommodation cavity 211, 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.

[0081] 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.

[0082] 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, 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 region 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.
