[0046] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0047] Reference below Figure 1-Figure 6 The air duct assembly provided in an embodiment of the present application is described, and the air duct assembly includes an inner tank, a shell 100, and a temperature sensing element 200.

[0048] The material of the liner includes but is not limited to ABS (acrylonitrile-butadiene-styrene copolymer) or modified polystyrene (HIPS), which has the characteristics of corrosion resistance and light weight. It should be noted that the shape and size of the liner can be designed according to actual needs, and this embodiment does not make specific restrictions on this.

[0049] The housing 100 is installed on the inner tank and forms a ventilation channel and a storage cavity, and the ventilation channel has a return air port, which is used to connect the ventilation channel and the storage cavity. It should be noted that the size and shape of the ventilation channel, the storage cavity and the return air port can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0050] It can be understood that the shell 100 is installed in the inner tank to divide the internal space of the inner tank into a ventilation channel and a storage cavity, and the gas is exchanged between the ventilation channel and the storage cavity through the return air port.

[0051] It should be noted that the ventilation channel also has an air supply port, that is, the gas with a lower temperature (i.e., cold air) in the ventilation channel enters the storage cavity from the air supply port, and at the same time, the gas with a higher temperature in the storage cavity enters the ventilation channel from the return air port, thereby realizing heat exchange between the ventilation channel and the storage cavity.

[0052] In this embodiment, the air supply port is located above the air return port.

[0053] It is understandable that since the density of low-temperature air flow is greater than that of high-temperature air flow, when the cold air enters the storage cavity from the air supply port, it will settle downwards. At this time, the original air in the storage cavity will passively flow upwards due to its relatively low temperature. The air supply port is set higher, and the cold air flows from high to low due to its relatively high density. A return air port is set at a low position, and the gas flowing out of the storage cavity flows to the ventilation channel through the return air port before passively flowing upwards, so that the storage cavity can be cooled more efficiently, and the cold air can also more easily cover the entire space of the storage cavity.

[0054] The temperature sensing element 200 is disposed in the ventilation passage and adjacent to the return air outlet. The connection relationship between the temperature sensing element 200 and the ventilation passage includes but is not limited to threaded connection, buckle 611 connection or gluing, etc. It should be noted that the size, quantity and specific position of the temperature sensing element 200 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0055] It should be noted that the temperature sensing element 200 is a key component for detecting and controlling temperature. It can convert temperature changes into electrical signals to achieve temperature perception and control. The temperature sensing element 200 includes but is not limited to thermistor sensors, thermocouple sensors, IC temperature sensors and resistance temperature detectors.

[0056] It can be understood that, on the one hand, by providing the temperature sensing element 200, the air duct assembly can adjust the ventilation volume according to the temperature change of the storage cavity, so that the temperature in the storage cavity can always be maintained within an appropriate range. On the other hand, since the temperature sensing element 200 is located in the ventilation channel and adjacent to the return air outlet, the influence of the placement of objects in the storage cavity on the temperature measurement accuracy of the temperature sensing element 200 can be avoided, thereby ensuring the refrigeration effect and extending the preservation time as much as possible.

[0057] According to the air duct assembly provided in the embodiment of the present application, by placing the temperature sensing element 200 in the ventilation channel and adjacent to the return air outlet, the influence of the placement of items in the storage cavity on the temperature measurement accuracy of the temperature sensing element 200 can be avoided, the refrigeration effect can be ensured, and the preservation time can be extended as much as possible.

[0058] In some embodiments, Figures 1 to 5As shown, the housing 100 includes an air duct cover 110 and an air duct cover plate 120, the air duct cover 110 is connected to the inner liner, and a part of the ventilation channel is formed between the air duct cover 110 and the inner liner; the air duct cover plate 120 is arranged at the lower part of the air duct cover 110, the temperature sensing element 200 is arranged on the air duct cover plate 120, and the bottom of the cover plate is spaced from the inner liner to form a return air port, and another part of the ventilation channel is formed between the cover plate and the inner liner. The materials of the air duct cover 110 and the air duct cover plate 120 can include but are not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. The connection method between the air duct cover 110 and the air duct cover plate 120 includes but is not limited to welding, bolt connection, rivet connection or buckle 611 connection.

[0059] It can be understood that the air duct cover 110 is connected to the inner tank, which realizes the formation of the ventilation channel and also plays a certain protective role for the inner tank. At the same time, the air duct cover 120 is located at the lower part of the air duct cover 110, and its bottom is spaced apart from the inner tank to form a return air port, so as to facilitate the gas to enter the ventilation channel from the bottom of the storage cavity and the return air port, extend the flow path of the gas for heat exchange, and make the temperature in the entire storage cavity as uniform as possible.

[0060] In this embodiment, an inner cavity for accommodating the fan 300 is formed in the air duct cover 110, so that the fan 300 accelerates the flow rate of gas flowing out of the ventilation channel from the air supply port and flowing into the ventilation channel from the air return port, thereby improving the cooling effect.

[0061] It should be noted that when the storage device is cooled, the fan 300 is turned on, and the cold energy output by the refrigeration device in the storage device enters the storage cavity through the partial ventilation channel formed between the air duct cover 110 and the inner tank after passing through the air supply port under the action of the fan 300. At the same time, the gas in the storage cavity returns to the partial ventilation channel formed between the air duct cover 120 and the inner tank through the return air port of the air duct cover 120, forming a circulating flow of cold air.

[0062] Exemplarily, the refrigeration device includes, but is not limited to, an evaporator.

[0063] In some embodiments, Figures 1 to 5 As shown, the inner wall of the air duct cover plate 120 close to the inner container is arc-shaped.

[0064] In some embodiments, Figures 1 to 5As shown, a plurality of baffles 400 are provided on the air duct cover plate 120, the baffles 400 are located in the ventilation channel, and the plurality of baffles 400 are spaced apart along the length direction of the air duct cover plate 120, for diverting the gas flowing into the ventilation channel from the return air port. The material of the baffle 400 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy, etc. The connection method between the baffle 400 and the air duct cover plate 120 includes but is not limited to welding, bolt connection, rivet connection or snap connection, etc. It should be noted that the shape, quantity and specific distribution of the baffle 400 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0065] It can be understood that by arranging a plurality of baffles 400 on one side of the air duct cover 120 close to the inner tank, the gas flowing in from the return air port can be effectively diverted in the ventilation channel, and the gas flow path and contact area can be increased, thereby reducing the turbulence and vibration of the air flow in the ventilation channel, thereby improving the ventilation efficiency, reducing the air flow noise, and further improving the cooling effect. At the same time, the structural stability of the air duct cover 120 is enhanced to prevent damage caused by air flow impact.

[0066] In this embodiment, the air duct cover plate 120 and the baffle plate 400 are integrally formed to ensure the overall structural strength of the housing 100 .

[0067] It is understandable that the duct cover plate 120 and the baffle plate 400 can be formed into an integral structure by injection molding, but different materials can also be used in the injection molding process to facilitate satisfying the different functions of the duct cover plate 120 and the baffle plate 400. For example, the duct cover plate 120 can be made of PP or PVC, and the baffle plate 400 can be made of silicone.

[0068] In some embodiments, Figures 1 to 5 As shown, the lower surface of the temperature sensing element 200 is flush with the lower surface of the baffle 400 .

[0069] It can be understood that by making the lower surface of the temperature sensing element 200 flush with the lower surface of the baffle 400, the temperature sensing element 200 is ensured to be located in the ventilation channel and adjacent to the return air outlet, while avoiding the baffle 400 from affecting the accuracy of the temperature measurement of the gas by the temperature sensing element 200 due to the diversion of the gas. It can also simplify the operation to facilitate subsequent cleaning and inspection, thereby improving maintenance efficiency.

[0070] In some embodiments, Figures 1 to 5 As shown, the temperature sensing element 200 is detachably connected to the housing 100 .

[0071] It can be understood that the detachable connection between the temperature sensing element 200 and the housing 100 provides many advantages such as easy maintenance, flexible adaptation, rapid fault diagnosis, simplified production and assembly, and optimized performance.

[0072] In this embodiment, Figures 1 to 5 As shown, a limiter 500 is also provided on the air duct cover plate 120, and the limiter 500 is provided adjacent to one of the baffles 400 and is located in the ventilation channel, so that a clamping space is formed between the air duct cover plate 120, the baffle 400 and the limiter 500, the top surface of the temperature sensing element 200 abuts against the inner wall of the air duct cover plate 120, and the outer side wall of the temperature sensing element 200 abuts against the side of the baffle 400 and the limiter 500 that are close to each other. The material of the limiter 500 includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. The connection method between the limiter 500 and the air duct cover plate 120 includes but is not limited to welding, bolt connection, rivet connection or buckle 611 connection. It should be noted that the shape and specific position of the limiter 500 can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0073] It can be understood that since the limiting member 500 is arranged on a side of the air duct cover 120 close to the inner tank and is spaced apart from one of the baffles 400, it limits the temperature sensing element 200 in the horizontal direction, and the top surface of the temperature sensing element 200 abuts against the inner wall of the air duct cover 120 to limit the temperature sensing element 200 in the vertical direction, ensuring that the limiting member 500 can only be inserted into the clamping space from below, ensuring the installation quality and performance of the temperature sensing element 200, preventing the temperature sensing element 200 from moving or vibrating in the ventilation channel, so as to achieve the accuracy of temperature measurement of the temperature sensing element 200, and also making the installation and disassembly of the temperature sensing element 200 simple, which helps to reduce maintenance costs and improve maintenance efficiency.

[0074] In this embodiment, the air duct cover plate 120 and the limiting member 500 are integrally formed to ensure the overall structural strength of the housing 100 .

[0075] It is understandable that the air duct cover plate 120 and the stopper 500 can be formed into an integral structure by injection molding, but different materials can also be used in the injection molding process to facilitate satisfying the different functions of the air duct cover plate 120 and the stopper 500. For example, the air duct cover plate 120 can be made of PP or PVC, and the stopper 500 can be made of silicone.

[0076] In some embodiments, Figures 1 to 4 As shown, along the length direction of the air duct cover plate 120 , the distance between the temperature sensing element 200 and the end of the air duct cover plate 120 is l, satisfying the following condition: 1 / 4L≤l≤3 / 4L, where L is the length of the air duct cover plate 120 .

[0077] It is understandable that, considering that defrosting may occur at the end of the air duct cover 120, a certain distance is created between the temperature sensing element 200 and the end of the air duct cover 120 by setting 1 / 4L≤l≤3 / 4L, thereby ensuring the accuracy and reliability of temperature measurement by the temperature sensing element 200.

[0078] In some embodiments, Figures 2 to 6 As shown, the air duct assembly further includes a wire harness 600, which is disposed on the housing 100 and is used to constrain the wire 700 connected to the temperature sensing element 200. The connection between the wire harness 600 and the housing 100 includes but is not limited to welding, bolt connection, rivet connection or buckle 611 connection.

[0079] It can be understood that the wiring harness 600 can effectively restrain the wires 700 of the temperature sensing element 200, prevent the wires 700 from being loose or entangled inside the air duct, and protect the wires 700 from mechanical damage, thereby reducing the risk of short circuit or electric shock, ensuring the continuous and stable operation of the temperature sensing element 200, improving the safety of the entire air duct assembly, and facilitating installation, maintenance and inspection work.

[0080] In some embodiments, Figure 2 and Figure 4 As shown, there are at least two wire harness parts 600, and at least two wire harness parts 600 are arranged on the duct cover plate 120 at intervals along the length direction of the duct cover plate 120, and the duct cover plate 120 is provided with avoidance holes, so that the wires 700 can pass through the avoidance holes and be constrained by the wire harness parts 600. It should be noted that the number and specific distribution of the wire harness parts 600 and the shape of the avoidance holes can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0081] In this embodiment, two wire bundling parts 600 are provided, and the wire bundling parts 600 and the avoidance opening 121 are both located at the upper part of the air duct cover plate 120 .

[0082] In some embodiments, Figures 2 to 6 As shown, the cable harness portion 600 includes a fixing seat 610 and a fitting member 620 . The fixing seat 610 is mounted on the housing 100 . Both ends of the fitting member 620 are respectively connected to the fixing seat 610 to form a cable harness ring, and the wire 700 is passed through the cable harness ring.

[0083] It can be understood that the fixing base 610 is installed on the air duct cover 120, which helps to reduce the displacement or damage of the wire 700 caused by vibration or other mechanical movement, and the wire harness ring formed by connecting the two ends of the matching piece 620 with the fixing base 610 can realize orderly management of the wire 700, avoid the wire 700 from being disorganized, and reduce the difficulty of maintenance and inspection.

[0084] In some embodiments, Figures 2 to 6As shown, the fixing base 610 and the housing 100 are detachably connected.

[0085] It can be understood that the detachable connection between the fixing base 610 and the air duct cover 120 provides many advantages such as easy maintenance, flexible adaptation, rapid fault diagnosis, simplified production and assembly, and optimized performance.

[0086] In this embodiment, Figures 2 to 6 As shown, one of the fixing base 610 and the air duct cover 120 is provided with a buckle 611, and one of the fixing base 610 and the shell 100 is provided with a slot 122, and the slot 122 is engaged with the buckle 611 to realize quick disassembly and assembly of the fixing base 610 and the air duct cover 120.

[0087] In this embodiment, the buckle 611 is in the shape of an arrow.

[0088] It is understandable that the arrow shape has a clear directionality, is easy to identify and operate, and reduces the possibility of misoperation. At the same time, the arrow-shaped buckle 611 can naturally guide the operation when inserting or removing, ensuring that the buckle 611 is correctly aligned and smoothly enters the corresponding slot 122, reducing errors during installation. In addition, the arrow-shaped buckle 611 can also provide a better grip and locking mechanism, ensuring that the connection between the buckle 611 and the slot 122 is more secure, and optimizing stress distribution: when the buckle 611 is subjected to force, it can more effectively disperse and transfer stress, reduce damage to the buckle 611 or the slot 122, and extend the service life.

[0089] In some embodiments, Figures 2 to 6 As shown, the inner diameter of the cable tie ring is adjustable.

[0090] It can be understood that by making the inner diameter of the wiring loop adjustable, on the one hand, it can accommodate wires 700 of different thicknesses, ensuring compatibility and flexibility. On the other hand, it can also adjust the inner diameter to adapt to the size of the wire 700 to more tightly fix the wire 700 and reduce the movement and vibration of the wire 700 inside the ventilation channel, thereby reducing the risk of failure caused by the instability of the wire 700 and providing flexibility for installation and maintenance.

[0091] In this embodiment, Figures 2 to 6 As shown, a slide groove 612 is provided on the fixing seat 610 , one end of the matching piece 620 is fixedly connected to the fixing seat 610 , and the other end is slidably connected to the slide groove 612 .

[0092] It is understandable that by making one end of the fitting 620 fixedly connected to the fixing seat 610 and the other end slidingly connected to the slide groove 612 in the up-down direction, the inner diameter of the cable tie ring can be quickly adjusted, which is convenient for installation and maintenance, and the design of the sliding connection can also reduce the wear between the fitting 620 and the fixing seat 610, which helps to extend the service life of the cable tie portion 600. It should be noted that although the fitting 620 can slide in the slide groove 612, it can also include the relative fixation between the fitting 620 and the slide groove 612 after the fitting 620 is properly positioned in the slide groove 612 by friction or other locking members, so as to ensure the fixing effect of the wire 700.

[0093] The embodiment of the present application also provides a storage device.

[0094] The storage device comprises a cabinet and the above-mentioned air duct assembly, and the air duct assembly is arranged in the cabinet.

[0095] It should be noted that the storage equipment in the embodiment can be understood as refrigeration storage equipment in a broad sense, including but not limited to refrigerators, freezers, display cabinets, beverage cabinets, wine cabinets, fresh-keeping cabinets, refrigerated vending machines and other refrigeration storage equipment. The storage equipment has various structural forms and a wide range of applications.

[0096] The cabinet body forms a placement cavity with a cabinet opening, and the placement cavity is used to install the air duct component. The material of the cabinet body includes but is not limited to hard plastic, stainless steel, aluminum alloy or titanium alloy. It should be noted that the shape and size of the cabinet body, the cabinet opening and the placement cavity can be designed according to actual needs, and this embodiment does not impose specific restrictions on this.

[0097] According to the storage device provided in the embodiment of the present application, by placing the temperature sensing element 200 in the air duct assembly in the ventilation channel and adjacent to the return air outlet, the influence of the placement of items in the storage cavity on the temperature measurement accuracy of the temperature sensing element 200 can be avoided, thereby ensuring the refrigeration effect and extending the preservation time as much as possible.

[0098] In some embodiments, the storage device further comprises a refrigeration device to obtain cold air. The refrigeration device includes but is not limited to a compressor, a condenser, an evaporator, a throttling device and other refrigeration accessories.

[0099] In this embodiment, the evaporator is disposed in the housing 100 .
