Description

Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to an air duct structure and a wine cabinet. Background Technique

[0002] With the improvement of living standards, consumers' demands for wine cabinets are no longer limited to the basic refrigeration function, but pay more attention to the accuracy of temperature control, the energy efficiency ratio, and the flexibility of storage space. Most of the existing wine cabinets use fixed-structured partitions to separate different temperature zones. The air duct designs inside these partitions are often relatively simple or there is no air duct design, and they cannot be flexibly adjusted according to actual needs.

[0003] Traditional air duct designs often lack a flexible adjustment mechanism, resulting in uneven air volume distribution between different temperature zones. Especially in the case of multi-layer partitions, the temperature difference between the upper layer and the lower layer may increase significantly due to uneven air volume distribution, affecting the preservation effect of wine products.

[0004] Therefore, an air duct structure and a wine cabinet are provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide an air duct structure and a wine cabinet, at least to solve one of the problems raised in the above background technique.

[0006] The technical solution of the utility model is as follows:

[0007] An air duct structure, comprising:

[0008] A housing, on which an air inlet and an air outlet are provided;

[0009] An air duct, which is located inside the housing. The air duct includes a communicating air inlet area and an air outlet area. The air inlet area is communicated with the air inlet, and the air outlet area is communicated with the air outlet. The air inlet area includes parallel first and second air inlet sides. The first air inlet side is close to the air inlet, and the second air inlet side is close to the air outlet area. The width of the first air inlet side is greater than the width of the second air inlet side. The air outlet area includes parallel first and second air outlet sides. The first air outlet side is close to the air inlet area, and the second air outlet side is close to the air outlet. The width of the second air outlet side is greater than the width of the first air outlet side;

[0010] A damper, which is arranged between the air inlet area and the air outlet area.

[0011] Further, there is one air inlet, and it is arranged at one end of the first air inlet side close to the air inlet.

[0012] Further, a wind-cutting block is provided in the air inlet area, and the wind-cutting block is arranged near one end of the first air inlet side away from the air outlet.

[0013] Further, fixing protrusions are provided on the wind-cutting block, and fixing grooves are provided on the housing corresponding to the fixing protrusions. The fixing grooves and the fixing protrusions cooperate to fix the wind-cutting block in the air duct.

[0014] Further, two air inlets are provided, and the two air inlets are evenly spaced on the first air inlet side of the air inlet area.

[0015] Further, both the air inlet area and the air outlet area are trapezoidal, the air outlet area is larger than the air inlet area, the air inlet area uniformly transitions from the first air inlet side to the second air inlet side, and the air outlet area uniformly transitions from the first air outlet side to the second air outlet side.

[0016] Further, the air inlet is opened on the rear plate of the housing, and the air outlet is opened on the upper plate of the housing.

[0017] Further, the air damper is an electric air damper.

[0018] The present utility model further provides a wine cabinet herein, including the above-mentioned air duct structure. At least two compartments are provided in the wine cabinet, and each compartment is separated by the air duct structure.

[0019] Further, the air duct communicates with the evaporator chamber of the wine cabinet through the air inlet, and the air duct communicates with each compartment in the wine cabinet through the air outlet.

[0020] The present utility model provides an air duct structure and a wine cabinet by improvement herein. Compared with the prior art, it has at least the following improvements and beneficial effects:

[0021] 1. The present utility model is provided with one or two air inlets for occasions where different air volumes need to be provided. When one air inlet is provided, the air inlet is arranged near one end of the first air inlet side. By arranging the air inlet near one end of the first air inlet side instead of in the center of the first air inlet side, customers can flexibly adjust the quantity and position of the air inlet according to actual needs. For example, when it is necessary to enhance the ventilation effect in a local area, a new air inlet can be opened at one end of the first air inlet side to meet the ventilation requirements in different scenarios. Without the need to replace the housing additionally, customers can operate by themselves, which is more flexible and convenient to use.

[0022] II. The utility model is provided with a wind-cutting block. By installing or not installing the wind-cutting block, the air duct can adapt to a single air inlet or two air inlets. When using a single air inlet, due to the shielding of the wind-cutting block, the cold air will directly flow to the air damper. The wind-cutting block can guide the cold air to form a more scientific and reasonable air flow path. This helps to reduce the resistance and eddy current during the cold air flow, enabling the cold air to enter the air outlet area more smoothly and quickly, thereby improving the overall efficiency of the air duct.

[0035] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0037] The present utility model provides a duct structure and a wine cabinet by improvement herein. The technical solution of the present utility model is as follows:

[0038] As Figure 1 shown,

[0039] A duct structure includes: a housing 1, a duct, and a damper 3. The duct is used for air intake and outlet, and the damper 3 is used to control the opening and closing of the duct.

[0040] An air inlet 11 and an air outlet 12 are formed on the housing 1. The air inlet 11 is used to send cold air into the duct, and the air outlet 12 is used to send the cold air in the duct out.

[0041] As Figure 2 and Figure 3 shown, the duct is located inside the housing 1, and the duct includes a communicating air inlet area 21 and an air outlet area 22. The air inlet area 21 is communicated with the air inlet 11, and the air outlet area 22 is communicated with the air outlet 12.

[0042] As Figure 2As shown, the air inlet area 21 includes a parallel first air inlet side 211 and a second air inlet side 212. The first air inlet side 211 is close to the air inlet 11, and the second air inlet side 212 is close to the air outlet area 22. The width of the first air inlet side 211 is greater than the width of the second air inlet side 212. By setting the width of the first air inlet side 211 to be greater than the width of the second air inlet side 212, the cold air in the air inlet area 21 can be gathered and directed to the air door 3. The air outlet area 22 includes a parallel first air outlet side 221 and a second air outlet side 222. The first air outlet side 221 is close to the air inlet area 21, and the second air outlet side 222 is close to the air outlet 12. The width of the second air outlet side 222 is greater than the width of the first air outlet side 221. By setting the width of the second air outlet side 222 to be greater than the width of the first air outlet side 221, the cold air can escape more evenly from the air outlet 12, without staying only in a local area, making the air outlet more uniform.

[0043] As Figure 3 As shown, both the air inlet area 21 and the air outlet area 22 are set to be trapezoidal. The air outlet area 22 is larger than the air inlet area 21. The air inlet area 21 uniformly transitions from the first air inlet side 211 to the second air inlet side 212, and the air outlet area 22 uniformly transitions from the first air outlet side 221 to the second air outlet side 222. The air inlet area 21 and the air outlet area 22 form a funnel shape. By reducing the cross-section where the air inlet area 21 enters the air outlet area 22, the flow rate of the gas increases when passing through. The increase in flow rate will cause the pressure to decrease, but at the outlet, due to the sharp reduction of the cross-section, the local pressure will be higher than that at the inlet, thus realizing the increase in air pressure, enabling more cold air to quickly enter the air outlet area 22.

[0044] The air door 3 is arranged between the air inlet area 21 and the air outlet area 22. The air door 3 is an electric air door 3, and the specific model is not limited in this embodiment.

[0045] As Figure 2 As shown, there is one air inlet 11, which is used for occasions where less air volume needs to be provided. The air inlet 11 is arranged at one end close to the first air inlet side 211. By arranging the air inlet 11 at one end close to the first air inlet side 211 instead of in the center of the first air inlet side 211, customers can flexibly adjust the number and position of the air inlets 11 according to actual needs. For example, when it is necessary to enhance the ventilation effect in a local area, a new air inlet 11 can be opened at one end of the first air inlet side 211 to meet the ventilation requirements in different scenarios. Without replacing the housing separately, customers can operate by themselves, which is more flexible and convenient to use.

[0046] It is easy to understand that if the air inlet 11 is arranged at one end of the first air inlet side 211, eddies and dead zones often occur when the cold air enters the air inlet area 21. The cold air in the air inlet area 21 does not flow smoothly, resulting in uneven temperature distribution and affecting the overall refrigeration effect. At the same time, the eddies will increase the turbulence intensity of the air flow, further reducing the refrigeration efficiency. To ensure that the air inlet area 21 of the air duct can adapt to the air inlet 11 arranged at one end of the first air inlet side 211 without affecting the air guiding effect. Therefore, a wind cutting block 23 is arranged in the air inlet area 21, and the wind cutting block 23 is arranged near one end of the first air inlet side 211 away from the air outlet 12. The wind cutting block 23 is used to block a part of the air inlet area 21. To avoid the situation that when only one air inlet 11 is set, the cold air will flow to the position where the wind cutting block 23 is located instead of directly flowing to the air door 3, and resistance and eddies will be generated during the flow of the air. Through the shielding of the wind cutting block 23, the cold air will directly flow to the air door 3, and the wind cutting block 23 can guide the cold air to form a more scientific and reasonable air flow path. This helps to reduce the resistance and eddies during the flow of the cold air, enabling the cold air to enter the air outlet area 22 more smoothly and quickly, thereby improving the overall efficiency of the air duct.

[0047] In some embodiments, fixing protrusions are arranged on the wind cutting block 23. As Figure 3 shown, the housing 1 is provided with a fixing groove 13 corresponding to the fixing protrusion, and the fixing groove 13 and the fixing protrusion cooperate to fix the wind cutting block 23 in the air duct. The fixing groove 13 and the fixing protrusion can be adhered by glue, or the fixing protrusion can be clamped by interference fit, or structures such as buckles can be provided for fixing. The specific fixing method is not limited in this embodiment.

[0048] As Figure 4 shown, two air inlets 11 are arranged, and the two air inlets 11 are evenly spaced on the first air inlet side 211 of the air inlet area 21. By arranging two air inlets, the air intake is more, which is suitable for use scenarios that require more air volume.

[0049] As Figure 1 shown, the air inlet 11 is opened on the rear plate of the housing 1, and the air outlet 12 is opened on the upper plate of the housing 1.

[0050] As Figure 5As shown in the figure, the present utility model further provides a wine cabinet 4 herein, which includes the above-mentioned air duct structure. At least two compartments 41 are provided in the wine cabinet 4, and each compartment 41 is separated by the air duct structure. The air duct is communicated with the evaporator chamber of the wine cabinet 4 through the air inlet 11, and the air duct is communicated with each compartment 41 in the wine cabinet 4 through the air outlet 12. The air inlet 11 sends the cold air generated in the evaporator chamber of the wine cabinet 4 into the air duct, and the air outlet 12 then sends the cold air into the compartment 41 to complete the cold air delivery.

[0051] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
