[0049] 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.

[0050] The present application provides a storage device 10 .

[0051] Among them, the storage device 10 may include but is not limited to a refrigerator, a vending cabinet, a vending machine, a retail cabinet, a storage cabinet, a display cabinet, a wine cabinet or an express cabinet, etc., and is not limited here.

[0052] Reference below Figure 1-Figure 4 A storage device 10 according to an embodiment of the present application is described.

[0053] In some embodiments, Figure 1 and Figure 3 As shown, the storage device 10 includes: an outer shell 11, an inner tank 13, a refrigeration chamber 15, a refrigeration circuit 19 and a purification system 16.

[0054] The inner liner 13 is installed in the outer shell 11, and the inner liner 13 forms a compartment 131; the refrigeration chamber 15 is arranged in the inner liner 13, and the refrigeration chamber 15 is connected with the compartment 131 through the air supply duct 143 and the return air duct 132; the evaporator 193 of the refrigeration circuit 19 is installed in the refrigeration chamber 15; the purification system 16 is installed in the outer shell 11, and the purification system 16 includes a separated fresh air channel 1612 and an exhaust channel 1613, and the fresh air channel 1612 and the exhaust channel 1613 can be selectively connected with the external environment. The purification system 16 has a first state and a second state. In the first state, the fresh air channel 1612 and the exhaust channel 1613 are both disconnected from the external environment. In the second state, the purification system 16 separates the refrigeration chamber 15 and the return air duct 132, the fresh air channel 1612 connects the refrigeration chamber 15 with the external environment, and the exhaust channel 1613 connects the return air duct 132 with the external environment.

[0055] The compartment 131 may include but is not limited to a refrigeration compartment, a freezing compartment or a temperature-changing compartment, etc., which is not limited here.

[0056] For example, in some embodiments, compartment 131 is a refrigerated compartment.

[0057] For example, in other embodiments, the compartment 131 includes a refrigeration compartment and a freezing compartment.

[0058] like Figure 1-Figure 3 As shown, the compartment 131 has an air inlet 1311 and an air outlet 1312 that are spaced apart from each other, the air supply duct 143 is connected between the air inlet 1311 and the refrigeration chamber 15, and the return air duct 132 is connected between the air outlet 1312 and the refrigeration chamber 15. The refrigeration chamber 15, the air supply duct 143, the compartment 131 and the return air duct 132 are connected end to end to form a loop, and the internal circulating air circulates in this loop.

[0059] like Figure 3 As shown, the refrigeration circuit 19 includes but is not limited to a compressor 191, a condenser 192, an evaporator 193 and a drying filter 194. The refrigeration circuit 19 achieves a refrigeration effect through an internal refrigerant circulation. The evaporator 193 installed in the refrigeration chamber 15 is used to cool the internal circulating air flowing through the refrigeration chamber 15, thereby achieving the supply of cold air to the compartment 131.

[0060] In the related art, some storage devices are provided with vents for selectively connecting the compartment with the outside environment. When the storage device is ventilated, fresh air from the outside environment enters the compartment through the vents, and odorous gas in the compartment is also discharged through the vents. However, in actual application of the above ventilation method, since the fresh air and the exhaust gas share the same vent, the two are mixed for a long time, resulting in the ventilation effect far from the expected.

[0061] In actual implementation, Figure 1 and Figure 2 As shown, Figure 1 Arrows are used to indicate the flow path of the gas in the first state. Figure 2 Arrows are used to indicate the flow path of the gas in the first state. In the first state, that is, when the storage device 10 does not start the purification and ventilation function, the purification system 16 is disconnected from the external environment to maintain the sealing of the internal environment of the storage device 10. In other words, the internal circulating air circulates in the loop formed by the refrigeration chamber 15, the supply air duct 143, the compartment 131 and the return air duct 132 to maintain the normal cooling of the compartment 131. In the second state, that is, when the storage device 10 starts the purification and ventilation function, the purification system 16 can cut off the air path connection between the refrigeration chamber 15 and the return air duct 132 by physical isolation means, the fresh air duct 1612 connects the refrigeration chamber 15 with the external environment, and the exhaust duct 1613 connects the return air duct 132 with the external environment. In this case, fresh air can enter the refrigeration chamber 15 from the fresh air duct 1612, and the evaporator 193 in the refrigeration chamber 15 absorbs a large amount of heat from the fresh air, and the low-temperature fresh air passes through the supply air duct 143. And the air inlet 1311 is sent into the compartment 131; at the same time, the odorous exhaust gas in the compartment 131 is discharged into the return air duct 132, and finally the exhaust gas is released into the external environment through the exhaust duct 1613. In this process, based on the separation of the fresh air duct 1612 and the exhaust duct 1613, and the isolation between the refrigeration chamber 15 and the return air duct 132, the mixing of the fresh air and the odorous exhaust gas is significantly reduced, so that the storage device 10 can quickly achieve the expected air exchange and purification effect in a short time after switching to the second state.

[0062] It should be noted that the storage device 10 may include a control panel, and the user may control the purification system 16 to switch between the first state and the second state by clicking the control panel.

[0063] The storage device 10 provided in the embodiment of the present application, through the above-mentioned independent fresh air channel 1612 and exhaust channel 1613, and the switchable purification system 16 state, minimizes the mixing between fresh air and odorous exhaust gas, realizes rapid and large-scale air replacement, significantly shortens the air exchange time, optimizes the air exchange effect, and at the same time, in the second state, sends fresh air into the compartment 131 through internal circulation, without increasing additional energy consumption, taking into account the purification demand and cooling demand of the compartment 131.

[0064] In some embodiments, Figure 1 and Figure 2 As shown, a heat-insulating layer 12 is provided between the outer shell 11 and the inner liner 13 ; the purification system 16 includes: a pre-buried pipe 161 .

[0065] The embedded pipe 161 passes through the thermal insulation layer 12 , and is provided with a partition rib 1611 to form a separated fresh air passage 1612 and an exhaust air passage 1613 .

[0066] In actual implementation, the assembly process of the embedded pipe 161 is as follows: before forming the insulation layer 12, the embedded pipe 161 is pre-installed between the inner liner 13 and the outer shell 11, and then the foaming material is filled between the inner liner 13 and the outer shell 11. After the foaming material is solidified to form the insulation layer 12, the embedded pipe 161 is not easy to move under the wrapping of the insulation layer 12.

[0067] In this embodiment, if Figure 1-Figure 4 As shown, the fresh air channel 1612 and the exhaust channel 1613 are formed in the same pipe, namely the embedded pipe 161. A partition rib 1611 is arranged inside the embedded pipe 161. The partition rib 1611 is used to divide the internal space of the embedded pipe 161 into independent fresh air channel 1612 and exhaust channel 1613 so that the fresh air and exhaust gas do not interfere with each other in the embedded pipe 161.

[0068] In other embodiments, the fresh air channel 1612 and the exhaust channel 1613 may also be formed in different pipes respectively.

[0069] The storage device 10 provided in the embodiment of the present application reduces the material usage and thus reduces the production cost through the structural design of integrating the fresh air duct 1612 and the exhaust duct 1613 into the embedded pipe 161 through the partition rib 1611. At the same time, the wrapping of the thermal insulation layer 12 reduces the risk of damage to the embedded pipe 161 due to temperature changes or physical pressure, and there is no need to introduce additional connectors, which greatly simplifies the assembly process and is conducive to promotion and use.

[0070] In some embodiments, Figure 1 and Figure 2 As shown, the partition rib 1611 is made of a heat-conducting material, and the airflows in the fresh air channel 1612 and the exhaust channel 1613 exchange heat with each other through the partition rib 1611 .

[0071] The thermally conductive material may be metal, rubber filled with ceramic particles, graphene or boron nitride, etc., which is not limited here.

[0072] For example, in some embodiments, the partition ribs 1611 are made of metal.

[0073] The partition rib 1611 physically separates the fresh air passage 1612 from the exhaust passage 1613 , while allowing the airflow in the fresh air passage 1612 and the exhaust passage 1613 to exchange heat through the partition rib 1611 .

[0074] In actual implementation, Figure 1 and Figure 2As shown, when fresh air is introduced into the fresh air channel 1612, the temperature of the fresh air is usually close to the external environment temperature, while the exhaust gas discharged from the exhaust channel 1613 still has a relatively low temperature because it has just left the compartment 131. Through the heat conduction effect of the partition rib 1611, the high-temperature fresh air in the fresh air channel 1612 can exchange heat with the low-temperature exhaust gas in the exhaust channel 1613. Before the fresh air enters the refrigeration chamber 15, the residual coldness of the exhaust gas is used to pre-cool the fresh air, thereby realizing energy recovery and utilization.

[0075] The storage device 10 provided in the embodiment of the present application is designed to exchange heat between the air flows in the fresh air channel 1612 and the exhaust channel 1613 through the partition ribs 1611. The fresh air that has not yet entered the refrigeration chamber 15 can absorb the remaining coldness of the exhaust gas, thereby realizing energy recovery and reuse, thereby significantly improving energy utilization efficiency and reducing the operating cost of the storage device 10.

[0076] In some embodiments, Figure 4 As shown, the end of the partition rib 1611 close to the external environment is provided with a first guide portion 16111 protruding toward the fresh air passage 1612 and a second guide portion 16112 protruding toward the exhaust passage 1613 .

[0077] In this embodiment, if Figure 1-Figure 4 As shown, the embedded pipe 161 and the partition rib 1611 are both extended in the front-to-back direction. Since the air inlet 1311 is located at the upper part of the compartment 131 and the air outlet 1312 is located at the lower part of the compartment 131, the fresh air channel 1612 is also arranged above the exhaust channel 1613 during design, so as to facilitate the layout of the air path in the second state. The first air guide 16111 can be designed in a triangular slope shape. Specifically, the protruding area of ​​the first air guide 16111 gradually increases from one end close to the compartment 131 to one end close to the external environment, so that the air inlet area of ​​the fresh air channel 1612 is in a constricted shape from the inside to the outside; the second air guide 16112 can be designed in a triangular slope shape. Specifically, the protruding area of ​​the second air guide 16112 gradually increases from one end close to the compartment 131 to one end close to the external environment, so that the air outlet area of ​​the exhaust channel 1613 is in a constricted shape from the inside to the outside. Therefore, under the guidance of the first guide part 16111, the inlet direction of the fresh air is inclined upward, and under the guidance of the second guide part 16112, the outlet direction of the exhaust gas is inclined downward, further reducing the mixing between the fresh air and the exhaust gas.

[0078] The storage device 10 provided in the embodiment of the present application reduces the intersection of fresh air during the entry process and exhaust gas during the exhaust process through the design of the above-mentioned first guide part 16111 and the second guide part 16112, increases the angle between the entry direction of the fresh air and the exit direction of the exhaust gas as much as possible, further reduces the mixing between the fresh air and the exhaust gas, and thus improves the cleanliness of the fresh air delivered to the chamber 131.

[0079] In some embodiments, Figure 1 and Figure 2 As shown, the storage device 10 also includes an air duct shell 14, which is arranged in the inner liner 13, and the refrigeration chamber 15 is located between the back wall of the inner liner 13 and the air duct shell 14, the air duct shell 14 forms an air supply duct 143, and a return air duct 132 is formed between the air duct shell 14 and the inner liner 13; the purification system 16 also includes: a partition 162 and a driving mechanism 163.

[0080] like Figure 1 and Figure 2 As shown, the partition 162 is movably mounted on the air duct housing 14 , and the partition 162 is suitable for moving to abut against the partition rib 1611 in the second state to separate the refrigeration chamber 15 and the return air duct 132 ; the driving mechanism 163 is used to drive the partition 162 to move.

[0081] The movable modes of the partition 162 include but are not limited to sliding, rotating, or sliding combined with rotating, etc., which are not limited here.

[0082] For example, in some embodiments, Figure 1 and Figure 2 As shown, the partition 162 moves in a sliding manner.

[0083] The driving method of the driving mechanism 163 may include but is not limited to electric, pneumatic or hydraulic, etc., which is not limited here.

[0084] For example, in some embodiments, the driving mechanism 163 is driven electrically.

[0085] In this embodiment, if Figure 1 and Figure 2As shown, the air duct housing 14 includes an air duct front cover 141 and an air duct rear cover 142, the air duct front cover 141 and the air duct rear cover 142 cover each other to define an air supply duct 143, and the bottom of the air duct front cover 141 and the bottom of the inner liner 13 define a return air duct 132. The partition 162 can be designed as a plate-like structure, the partition 162 and the partition rib 1611 both extend in the front-to-back direction and are arranged oppositely, the partition 162 can be movably mounted on the air duct rear cover 142, and the driving mechanism 163 can be installed in the air duct housing 14. In the first state, the partition 162 and the partition rib 1611 can be spaced apart by a certain distance, and the airflow in the return air duct 132 can enter the refrigeration chamber 15 through the gap between the partition 162 and the partition rib 1611; in the second state, the driving mechanism 163 drives the partition 162 to continuously move toward the partition rib 1611 until the partition 162 stops at the partition rib 1611, so that the original air path between the refrigeration chamber 15 and the return air duct 132 is completely blocked by the partition 162, and the refrigeration chamber 15 and the return air duct 132 are blocked by the partition 162 in the up and down directions.

[0086] The storage device 10 provided in the embodiment of the present application can quickly separate the refrigeration chamber 15 and the return air duct 132 when air change is required through the arrangement of the above-mentioned partition 162 and the driving mechanism 163, so that fresh air can directly enter the refrigeration chamber 15 without being affected by the exhaust gas in the return air duct 132, thereby improving the efficiency of air purification in the compartment 131.

[0087] In some embodiments, Figure 4 As shown, the driving mechanism 163 includes an electromagnetic push rod 1631 and a reset member 1632 .

[0088] like Figure 1 , Figure 2 and Figure 4 As shown, the electromagnetic push rod 1631 is installed on the air duct shell 14, and the electromagnetic push rod 1631 is configured to push the partition 162 to abut the partition rib 1611 when powered on; the reset member 1632 is elastically connected between the air duct shell 14 and the partition 162, and the reset member 1632 is used to drive the partition 162 to reset when the electromagnetic push rod 1631 is powered off.

[0089] The push rod portion of the electromagnetic push rod 1631 is directly or indirectly connected to the partition 162 so that the partition 162 can be pushed to move when power is turned on. The connection between the electromagnetic push rod 1631 and the partition 162 can be achieved through a mechanical connector (such as a connecting rod, a pin, etc.) or by direct embedding, which is not limited in this application.

[0090] like Figure 1 and Figure 2As shown, one end of the reset member 1632 can be connected to the air duct front cover 141, and the other end can be connected to the partition 162. The connection between the reset member 1632 and the partition 162 can be achieved by gluing or snapping, etc., and this application does not limit this.

[0091] The reset member 1632 may be an elastic element, such as a spring, an elastic sheet or an elastic rubber sleeve, etc., which is not limited here. The reset member 1632 can be deformed after being subjected to an external force, and return to its original state after the external force disappears.

[0092] For example, in some embodiments, Figure 4 As shown, the reset member 1632 is a spring.

[0093] In actual implementation, Figure 1 , Figure 2 and Figure 4 As shown, the user can send instructions to the purification system 16 by clicking on the control panel. After receiving the instructions, the purification system 16 switches from the first state to the second state. At this time, the electromagnetic push rod 1631 is connected to the power supply. The electromagnetic push rod 1631 in the power-on state pushes the partition 162 in the direction close to the partition rib 1611, that is, pushes the partition 162 outward. During the pushing process, the elastic force of the reset member 1632 gradually increases until the end of the partition 162 abuts against the end of the partition rib 1611, and the elastic force of the reset member 1632 reaches a maximum value. The push rod continues to provide thrust to keep the partition 162 in the position where it stops at the partition rib 1611. The ventilation process ends, and the control system of the storage device 10 can send instructions to the purification system 16. After receiving the instructions, the purification system 16 switches from the second state back to the first state, the electromagnetic push rod 1631 is disconnected from the power supply, and the electromagnetic push rod 1631 in the power-off state retracts, the thrust disappears, and the partition 162 returns to its original position driven by the reset member 1632.

[0094] It should be noted that in order to improve the movement accuracy and reliability of the partition 162, a limiting structure can be set at one end of the partition 162 close to the chamber 131. When the thrust exerted on the partition 162 is too large, the limiting structure can stop the air duct rear cover 142 to prevent the partition 162 from being directly pushed out of the air duct shell 14, thereby reducing the risk of failure of the purification system 16.

[0095] The storage device 10 provided in the embodiment of the present application realizes dynamic control of the partition 162 through the coordinated work of the above-mentioned electromagnetic push rod 1631 and the reset member 1632. The user can change the position of the partition 162 at any time by controlling the power-on state of the electromagnetic push rod 1631, thereby improving the overall response speed of the purification system 16. The use of the reset member 1632 enables the partition 162 to maintain a stable posture or position when the electromagnetic push rod 1631 loses power, thereby solving the problem of damage to the storage device 10 caused by failure of the electromagnetic push rod 1631, thereby improving the stability and reliability of the storage device 10.

[0096] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the purification system 16 also includes: a first fan 166 .

[0097] The first fan 166 is disposed in the exhaust passage 1613 , and is used to drive the gas in the chamber 131 to flow to the external environment.

[0098] like Figure 1 and Figure 2 As shown, the storage device 10 further includes a second fan 18 , which is installed in the air duct housing 14 and is used to drive the gas in the refrigeration chamber 15 to flow toward the compartment 131 .

[0099] It is understandable that, since the interior of the storage device 10 is a low-pressure environment, after the air exchange begins, some of the fresh air from the outside will enter the chamber 131, but the original exhaust gas in the chamber 131 is difficult to be discharged in large quantities in a short period of time due to pressure balance. The time taken for the air exchange to be effective is too long, which seriously affects the air exchange efficiency.

[0100] In the case where the purification system 16 includes the first fan 166, based on the first fan 166 being located in the exhaust passage 1613, in the second state, the first fan 166 is turned on, so that at this time the exhaust passage 1613 is in a low-pressure state, thereby prompting the exhaust gas in the compartment 131 to diffuse rapidly to the exhaust passage 1613 driven by the pressure difference, thereby reducing the residence time of the exhaust gas in the compartment 131, and based on the second fan 18 being installed in the air duct shell 14, the air supply duct 143 is in a low-pressure state, thereby prompting the fresh air in the refrigeration chamber 15 to diffuse rapidly to the compartment 131 driven by the pressure difference. By the above-mentioned fresh air pouring into the compartment 131 in large quantities driven by the second fan 18, and the exhaust gas being discharged from the compartment 131 in large quantities driven by the first fan 166, the mixing between the fresh air and the exhaust gas is minimized to further optimize the purification effect.

[0101] In some embodiments, Figure 1 and Figure 2 As shown, the storage device 10 further includes a ventilation door 17 .

[0102] The ventilation door 17 can selectively block the inlets of the fresh air passage 1612 and the exhaust passage 1613 .

[0111] The first filter device 164 can be connected to the embedded pipe 161 through a flange, a snap or other connectors, and the first filter device 164 needs to be replaced or cleaned regularly.

[0112] Among them, the first filtering device 164 can adopt a variety of filtering technologies, such as mechanical filtration, electrostatic filtration or activated carbon adsorption, to remove pollutants such as dust, bacteria, and odor in the fresh air.

[0113] The storage device 10 provided in the embodiment of the present application realizes purification and cleaning of the fresh air coming in from the external environment through the setting of the above-mentioned first filtering device 164, which can significantly improve the air quality inside the storage device 10, help reduce the risk of contamination of stored items, improve the quality and shelf life of stored items, thereby enhancing the user's sense of use and experience.

[0116] The second filter device 165 may be integrated at the outlet or inside of the exhaust passage 1613 to filter the exhaust gas from the compartment 131 by physical or chemical means to improve the cleanliness of the exhaust gas entering the external environment.

[0117] The second filter device 165 can be connected to the embedded pipe 161 through a flange, a buckle or other connectors, and the second filter device 165 needs to be replaced or cleaned regularly.

[0118] The second filter device 165 may use a variety of filtering technologies, such as mechanical filtration, electrostatic filtration or activated carbon adsorption, to remove pollutants in the exhaust gas, such as odor, moisture, harmful gases, etc.

[0119] The storage device 10 provided in the embodiment of the present application realizes purification and cleaning of the exhaust gas discharged from the compartment 131 through the setting of the above-mentioned second filtering device 165, which helps to reduce the pollutants discharged into the external environment by the storage device 10, reduces the impact on the surrounding environment, and improves the air quality of the external environment, thereby helping to improve the user's comfort and experience.

At the same time, it helps to simplify the overall structure of the storage device 10, reduce intermediate links such as pipes and connectors, reduce the complexity and failure rate of the purification system 16, and improve the overall performance and stability of the purification system 16. On the other hand, placing the purification system 16 and the refrigeration chamber 15 behind the compartment 131 can optimize the overall spatial layout of the storage device 10. This design makes the storage space more spacious and convenient for users to store and retrieve items. At the same time, it helps to reduce interference and complexity with the front of the storage device 10, and improve the overall aesthetics and ease of use of the storage device 10. On the other hand, the purification system 16 and the refrigeration chamber 15 may generate certain noise and vibration during operation. Placing the two behind the compartment 131 can minimize the impact of these interferences on stored items and users. At the same time, this layout also helps to reduce the overall noise level of the storage device 10 and improve the user experience. On the other hand, placing the purification system 16 and the refrigeration chamber 15 behind the compartment 131 can make these functional components more centralized and easy to access, which helps to simplify the maintenance and maintenance of the storage device 10, such as replacing filters, cleaning components or troubleshooting, etc. At the same time, this design also facilitates professionals to conduct regular inspections and repairs of the equipment to maintain the long-term stable operation of the storage device 10.

[0122] The storage device 10 provided in the embodiment of the present application, through the layout design that the above-mentioned purification system 16 and the refrigeration chamber 15 are both located behind the compartment 131, accelerates the flow efficiency of fresh air and exhaust gas, reduces intermediate links such as pipelines and connectors, thereby reducing the complexity and failure rate of the purification system 16, and further improves the overall performance and stability of the purification system 16, while helping to reduce the overall noise level of the storage device 10, thereby improving user experience and improving the maintainability of the entire storage device 10.
