[0002] 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 a compressor, a condenser, a capillary tube, an evaporator, etc. Through the continuous circulation of the refrigerant, the heat inside the freezer is brought outside the freezer to achieve the purpose of cooling.

[0003] In order to reduce the problem of condensation inside the freezer, the air-cooled method can be used for refrigeration. A housing 120 is provided in the freezer. An air outlet and an air return opening are provided on the housing 120. The cold air is circulated between the air outlet and the air return opening through a fan to achieve cooling. In order to enable the cold air to form multiple different circulation areas and improve the refrigeration effect, more than one air outlet can be provided on the housing 120. However, in the related art, affected by the positions of different air outlets, the temperature difference inside the freezer is likely to be large, resulting in poor refrigeration effect. Summary of the Utility Model

[0004] This application aims to at least solve the technical problem of poor refrigeration effect to a certain extent. For this purpose, this application provides an air duct module and a horizontal freezer.

[0008] Wherein, the area ratio of the first air outlet to the second air outlet is greater than 1.2.

[0009] The first air outlet is located above the second air outlet, and the second air outlet is located above the air return opening. That is, the first air outlet is closer to the top opening of the horizontal freezer than the second air outlet. Therefore, the cold loss of the cold air blown out from the first air outlet is greater than that of the cold air blown out from the second air outlet. Since the total area ratio of the first air outlet to the second air outlet is greater than 1.2, the cold air volume blown out from the first air outlet is more. Thus, the cold loss at the first air outlet can be compensated to a certain extent, the temperature difference of the cold air at the first air outlet and the second air outlet is reduced, the temperature inside the freezer is made more uniform, and the refrigeration effect is improved.

[0010] In some embodiments, the area ratio of the air return opening to the first air outlet and the second air outlet is greater than 1.2.

[0011] In some embodiments, the second air outlet is provided with an air outlet panel, and the air outlet panel has a plurality of air guiding rib strips, and the air guiding rib strips are arranged obliquely downward.

[0033] 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.

[0034] In order to reduce the problem of condensation inside the freezer, an air-cooling method can be used for refrigeration. A housing 120 is provided in the freezer, and an air outlet and an air return opening are provided on the housing 120. The cold air is circulated between the air outlet and the air return opening by a fan to achieve cooling. In order to enable the cold air to form multiple different circulation areas and improve the refrigeration effect, more than one air outlet can be provided on the housing 120. However, in the related art, affected by the positions of different air outlets, the temperature difference inside the freezer is likely to be large, 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 compensate for the cold air loss at the first air outlet to a certain extent, reduce the temperature difference of the cold air at the first air outlet and the second air outlet, make the temperature inside the freezer more uniform, and improve the refrigeration effect.

[0035] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0036] Please refer to Figures 1-6 , an air duct module 100 is provided in an embodiment of the present application. The air duct module 100 provided in the embodiment of the present application is mainly applied to a refrigeration device. The air duct module 100 provided in the embodiment of the present application can compensate for the cold loss at the first air outlet 112 to a certain extent, reduce the temperature difference of the cold air at the first air outlet 112 and the second air outlet 113, make the temperature inside the freezer more uniform, and improve the refrigeration effect.

[0037] 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 embodiment 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.

[0038] 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 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.

[0039] 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 of the horizontal freezer 10 in the width direction X, so that the air blown out of the freezer can cover the side surface formed by the length direction and the width direction X as much as possible. Make the air blown out of the freezer cover the inside of the entire cabinet 200, and improve the uniformity of freezing as much as possible.

[0040] 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 left and right respectively, 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.

[0041] Please refer to Figure 1 and Figure 2, 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, a second air outlet 113, and a return air inlet 114 that communicate 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 return air inlet 114; the flow guiding member 130 is installed in the installation cavity 124 and can enable external air to enter the installation cavity 124 through the return air inlet 114, and the air in the installation cavity 124 to flow out of the installation cavity 124 from the first air outlet 112 and / or the second air outlet 113;

[0042] Among them, the area ratio of the first air outlet 112 to the second air outlet 113 is greater than 1.2.

[0043] The air duct module 100 is applied to a refrigeration device (horizontal freezer 10) and is installed in the cabinet 200 of the refrigeration device (horizontal freezer 10). It can make the air in the refrigeration device (horizontal freezer 10) flow, so that the air in the refrigeration device (horizontal freezer 10) can be blown to the frozen items after being cooled by the evaporator. 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 roughly the same, and reduce the temperature difference in the same chamber.

[0044] 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 of external structures to the flow guiding member 130 and the like.

[0045] 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 in the refrigeration device can continuously flow to the evaporator, and after being cooled by the evaporator, it is blown to the frozen items again.

[0046] 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.

[0047] The first air outlet 112, the second air outlet 113, and the return air inlet 114 are arranged in order from high to low. The first air outlet 112 is close to the top of the cabinet 200, the return air inlet 114 is close to the bottom of the cabinet 200, and the second air outlet 113 is roughly arranged in the middle area of the cabinet 200, so that the cold air can form multiple different circulation areas and improve the refrigeration effect.

[0048] 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. By providing a second air outlet 113 between the first air outlet 112 and the air return opening 114, the cold air can be made to flow out approximately from the middle area of the cabinet body 200 and can quickly blow towards the bottom area of the cabinet body 200. Through the cooperation of the first air outlet 112 and the second air outlet 113, the cold air can be blown more evenly towards different areas inside the cabinet body 200, thereby making the refrigeration effect better.

[0049] The top of the cabinet body 200 has an opening 221 for the user to take items. When the opening 221 is in the open state, some of the cooling capacity inside the cabinet body 200 will be lost to the outside of the cabinet body 200 through the opening 221. Since 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, that is, the first air outlet 112 is closer to the opening 221 of the cabinet body 200 than the second air outlet 113. Therefore, when the opening 221 is open, the loss of the cooling capacity of the cold air blown out from the first air outlet 112 will be greater than that of the cold air blown out from the second air outlet 113, making the temperature in the upper part of the cabinet body 200 higher than that in the lower part, and the temperature is uneven. Since the area ratio of the first air outlet 112 to the second air outlet 113 is greater than 1.2, that is, the area of the first air outlet 112 is larger than the area of the second air outlet 113 and is more than 1.2 times the area of the second air outlet 113, the amount of cold air blown out from the first air outlet 112 is more. Thus, the loss of the cooling capacity at the first air outlet 112 can be compensated to a certain extent, reducing the temperature difference between the cold air at the first air outlet 112 and the second air outlet 113, making the temperature inside the freezer more uniform and improving the refrigeration effect.

[0050] Specifically, the area ratio of the first air outlet 112 to the second air outlet 113 can be 1.3, 1.4, 1.5, 1.6, 1.7, etc.

[0051] In some embodiments, the area ratio of the air return opening 114 to the first air outlet 112 and the second air outlet 113 is greater than 1.2.

[0052] The area ratio of the air return opening 114 to the first air outlet 112 and the second air outlet 113 is greater than 1.2, that is, the area of the air return opening 114 is greater than the total area of the first air outlet 112 and the second air outlet 113 combined, and the area of the air return opening 114 is more than 1.2 times the total area of the first air outlet 112 and the second air outlet 113 combined. Since the air inside the cabinet 200 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. Therefore, the area of the air return opening 114 being greater than the total area of the first air outlet 112 and the second air outlet 113 combined can make the air flow more smoothly and improve the cooling efficiency of the refrigerator.

[0053] Moreover, the area of the air return opening 114 being greater than the total area of the first air outlet 112 and the second air outlet 113 combined can also improve the situation where cold air accumulates in some areas, resulting in too low local temperature while other areas may have insufficient cooling.

[0054] Specifically, the area ratio of the air return opening 114 to the first air outlet 112 and the second air outlet 113 can be 1.3, 1.4, 1.5, 1.6, 1.7, etc.

[0055] Please refer to Figure 1 and Figure 3 , in some embodiments, the second air outlet 113 is provided with an air outlet panel 116, and the air outlet panel 116 has a plurality of air guiding rib strips 116a, and the air guiding rib strips 116a are arranged to incline downward.

[0056] To ensure the cold air volume of the second air outlet 113, the area of the opening 221 of the second air outlet 113 is not set to be particularly small. Also, since the second air outlet 113 is provided at the top of the cabinet 200, during the process of users taking and placing things, it is easy for some small-sized items to enter the inside of the housing 120 from the second air outlet 113. Setting the air outlet panel 116 on the second air outlet 113 can reduce the opening area of a single hole of the second air outlet 113, and thus can reduce the risk of small-sized items entering the housing 120 from the second air outlet 113. The air outlet panel 116 is an air outlet grille, and a plurality of air guiding rib strips 116a are arranged at intervals along the Z direction.

[0057] When the opening 221 of the horizontal freezer 10 is opened, it is vulnerable to the attachment of humid air to form condensed water. The condensed water will flow downward along the surface of the housing 120 under the action of gravity. If the condensed water flows into the second air outlet 113, in the frozen state, the condensed water is likely to freeze and block the second air outlet 113. Therefore, a plurality of air guiding rib strips 116a are arranged to incline downward, which can provide guidance for the condensed water flowing into the second air outlet 113, so as to facilitate the flow of the condensed water, make the condensed water flow downward along the air guiding rib strips 116a to the outside of the second air outlet 113, reduce the condensed water staying in the second air outlet 113, and thus improve the situation that the condensed water freezes and blocks the second air outlet 113.

[0058] In some embodiments, the included angle between the air guiding rib strip 116a and the horizontal plane is 0° to 80°.

[0059] That is, the downward inclination angle of the air guiding rib strip 116a is 0° to 80°. Therefore, when the condensed water flows into the second air outlet 113, it will flow downward along the air guiding rib strip 116a to the outside of the second air outlet 113, reduce the condensed water staying in the second air outlet 113, and thus improve the situation that the condensed water freezes and blocks the second air outlet 113. Specifically, the included angle between the air guiding rib strip 116a and the horizontal plane can be 15°, 25°, 45°, 55°, 75°, etc., and there is no limitation on this.

[0060] In some embodiments, a diversion rib strip 117 is arranged on the periphery of the second air outlet 113. The diversion rib strip 117 protrudes relative to the air outlet panel 116, and at least part of the diversion rib strip 117 is located above the air outlet panel 116.

[0061] Since the diversion rib strip 117 protrudes relative to the air outlet panel 116 and at least part of the diversion rib strip 117 is located above the air outlet panel 116, when the condensed water flows to the diversion rib strip 117 above the air outlet panel 116, under the limiting action of the diversion rib strip 117, most of the condensed water cannot continue to flow into the second air outlet 113, but flows along the diversion rib strip 117. That is, before the condensed water flows into the second air outlet 113, the diversion rib strip 117 blocks the condensed water, so the condensed water flowing into the second air outlet 113 is greatly reduced, and the situation that the condensed water freezes and blocks the second air outlet 113 is improved.

[0062] The diversion rib strip 117 can be arranged around the periphery of the air outlet panel 116, that is, the diversion rib strip 117 can be annular and surround the air outlet panel 116. In this way, the periphery of the air outlet panel 116 is protected and limited by the diversion rib strip 117, so that the condensed water flowing into the second air outlet 113 can be further reduced, and the situation that the condensed water freezes and blocks the second air outlet 113 is improved.

[0063] In some embodiments, the diversion rib 117 has a diversion surface 117a that is inclined downward, and at least a part of the diversion surface 117a is located above the air outlet panel 116.

[0064] Since the diversion surface 117a is inclined downward and at least a part of the diversion surface 117a is located above the air outlet panel 116, when the condensed water flows to the diversion rib 117 above the air outlet panel 116, the diversion surface 117a will provide guidance to the condensed water, causing the condensed water to flow downward along the diversion surface 117a. Under the guiding action of the diversion surface 117a, the flow of the condensed water can be accelerated, thereby further reducing the retention of the condensed water at the second air outlet 113 and reducing the condensed water flowing into the second air outlet 113.

[0065] In some embodiments, the angle between the diversion surface 117a and the horizontal plane is 0° to 60°.

[0066] That is, the angle of the diversion surface 117a inclined downward is 0° to 60°. Therefore, when the condensed water flows to the diversion rib 117 above the air outlet panel 116, the diversion surface 117a can provide guidance to the flow of the condensed water, reducing the retention of the condensed water at the second air outlet 113. Specifically, the angle between the diversion surface 117a and the horizontal plane can be 10°, 20°, 30°, 40°, 50°, etc.

[0067] In some embodiments, please refer to Figure 1 and Figure 2 , the air outlet area of the first air outlet 112 is arc-shaped.

[0068] 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 being arc-shaped enables the cold air blown out from the first air outlet 112 to have multiple different directions in the height direction Z. Furthermore, the cold air blown out from the first air outlet 112 can blow to different heights inside the horizontal freezer 10, allowing the cold air to flow at different heights inside the horizontal freezer 10 and covering different areas of the horizontal freezer 10 as much as possible, thereby improving the freezing effect.

[0069] 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.

[0070] 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.

[0071] In some embodiments, at least a portion of the first air outlet 112 is arc-shaped.

[0072] 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 deflected by the door body 230 of the horizontal door body 230, it can flow to the other side of the accommodation cavity in the width direction X, so that the side of the accommodation cavity 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 as much as possible, and further improving the refrigeration effect as much as possible.

[0073] Since the air outlet direction of the first air outlet 112 is arc-shaped, it has an upward air outlet direction and also a leftward air outlet direction at the same time, 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 blow out air at different levels and can freeze items at different positions.

[0074] In some embodiments, at least a portion 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 portion of the first air outlet 112 is arc-shaped may mean that the entire first air outlet 112 is arc-shaped, or a portion of the first air outlet 112 is arc-shaped and the other portion is linear. Specifically, it may not be limited.

[0075] 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 deflected 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.

[0076] Based on the same inventive concept, please refer to Figures 4-6 , an embodiment of the present application further provides a horizontal freezer 10, including a cabinet body 200 and an air duct module 100. The air duct module 100 is installed within the cabinet body 200, and the first air outlet 112 is located at the top of the cabinet body 200.

[0077] 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, compressor, evaporator, condenser, etc., and can also play a role in protecting the above-mentioned electronic components and the like.

[0078] 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 main body 220 has a receiving cavity 211, and the items to be refrigerated are arranged in the receiving cavity 211. The cold air blown out by the air duct module 100 freezes the items. The main body 220 includes an inner liner and an outer shell. The inner liner and the outer shell are filled with a foaming layer. There is an electrical cavity for accommodating the compressor between the inner liner and the outer shell, and the electrical control box is also arranged in the electrical cavity.

[0079] The air duct module 100 is arranged in the receiving cavity 211, and both the first air outlet 112 and the air return port 114 are communicated with the receiving cavity 211. The air duct module 100 blows the cold air cooled by the evaporator from the first air outlet 112 into the receiving cavity 211. The gas in the receiving cavity 211 can return to the vicinity of the evaporator through the air return port 114, and after being cooled by the evaporator, it is blown into the receiving 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. According to the self - 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 receiving 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, along the height direction of the cabinet body 200, the second air outlet 113 is located at 3 / 5 - 4 / 5 of the cabinet body 200.

[0082] Among them, the second air outlet 113 is arranged at 3 / 5 - 4 / 5 of the cabinet body 200, that is, along the height direction Z of the cabinet body 200, the second air outlet 113 is approximately located at 0.6 - 0.8 of the cabinet body 200, so that the second air outlet 113 is approximately located in the middle area of the horizontal freezer 10 in the height direction Z, enabling the horizontal freezer 10 to directly blow on the items in the receiving cavity 211 and freeze the items in the area near the air duct module 100, improving the refrigeration effect.
