Abstract
Description
Technical Field
[0001] This utility model belongs to the field of storage cabinet technology, specifically, it relates to a takeaway cabinet with a ventilation, sterilization and disinfection system. Background Technology
[0002] With social development and increasingly convenient living, the food delivery industry has developed rapidly. As an emerging facility to solve the "last 100 meters" delivery problem, food delivery lockers have become increasingly popular in recent years. However, their hygiene management issues have become increasingly prominent. Food delivery lockers are generally poorly cleaned, with oil stains, grime, and unpleasant odors from leftover food. These hygiene hazards can easily breed bacteria (such as E. coli and mold), which can lead to food safety problems.
[0003] To ensure the safety and hygiene of takeout food, we designed a takeout locker with a ventilation, sterilization, and disinfection system. Based on the existing takeout locker, it adds purification, disinfection, deodorization, and ventilation systems. These systems are integrated into the locker's concealed design, maintaining a clean and aesthetically pleasing appearance. This design provides a safe last 100 meters for those ordering takeout.
[0004] Patent document CN222619191U discloses a ventilation structure for a self-service takeout locker, including a support mechanism and a storage mechanism for storing takeout food, which is fixed above the support mechanism. This invention, through the storage mechanism, allows the controller to operate a corresponding electric push rod after the takeout food is placed. The electric push rod retracts, causing a baffle to move, thus removing the obstruction of the activated carbon filter layer. Simultaneously, a valve on the corresponding third pipe opens, and the controller controls a single-sided fan to operate. Outside air, under negative pressure, is filtered through the filter and enters the fixed box. Air inside the fixed box, under the action of the fan, enters the first pipe, then the second pipe, and finally the third pipe into the placement chamber. As the air in the placement chamber gradually increases, some air is filtered through the activated carbon filter layer and discharged under the influence of the air pressure difference.
[0005] Although patent document CN222619191U has the function of purifying the odor inside the takeaway cabinet and preventing odor gases from spreading into the air, the activated carbon filter used in it needs to be replaced frequently, which is inconvenient to use.
[0006] To more easily and effectively eliminate residual odors in food delivery lockers, reduce manpower, and ensure a hygienic environment, this invention designs a food delivery locker with a ventilation, sterilization, and disinfection system, thus solving the aforementioned problems. Utility Model Content
[0007] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a takeaway cabinet with a ventilation, sterilization and disinfection system.
[0008] According to the present invention, a takeaway cabinet with a ventilation, sterilization, and disinfection system includes: a cabinet body with several partitioned chambers; cabinet doors are provided at the front of the corresponding chambers; an insertable sterilization and deodorization device is provided at the rear of the cabinet body; the insertable sterilization and deodorization device includes several exhaust ducts that are respectively connected to the cabinet chambers and extend to the top of the cabinet body; an exhaust fan is connected to the top of the exhaust duct to drive the air in the cabinet chambers to be discharged; electric air valves are respectively installed at the connecting ends of the exhaust ducts to the corresponding cabinet chambers; the electric air valves can individually connect or cut off the air between the exhaust ducts and the corresponding cabinet chambers; a pipe-laying interlayer is provided at the rear of the cabinet body, and the exhaust ducts are housed in the pipe-laying interlayer; negative ion disinfection devices are respectively provided in the cabinet chambers near the connecting points of the exhaust ducts.
[0009] By adopting the above technical solution, each chamber's exhaust duct is equipped with an electric air valve, which can be opened or closed individually to avoid unnecessary energy waste. At the same time, it isolates the connection between each chamber. Each chamber is equipped with a negative ion disinfection device, which actively kills bacteria and viruses by releasing high concentrations of negative ions and decomposes odor molecules, reducing the need for manual intervention.
[0010] Preferably, the insertable sterilization and deodorization device further includes exhaust branch pipes and exhaust manifolds. The exhaust branch pipes are connected to the exhaust ducts at intervals and are arranged in the horizontal or vertical rows corresponding to the cabinets. The exhaust manifolds are connected to the exhaust branch pipes at intervals and extend and connect to the cabinet chambers in the horizontal or vertical rows corresponding to the exhaust branch pipes. Electric air valves are installed at the exhaust manifolds.
[0011] By adopting the above technical solution, the exhaust manifold can be directly connected to adjacent chambers in the same horizontal or vertical row, reducing the length of the airflow path, reducing wind resistance, and enabling the effect of starting and stopping by area.
[0012] Preferably, at most one electric air valve is connected to the exhaust manifold corresponding to the exhaust branch pipe.
[0013] By adopting the above technical solution, the simultaneous operation of multiple electric air valves in the same horizontal or vertical row can be avoided, thus reducing the ventilation effect.
[0014] Preferably, the exhaust duct, exhaust branch duct, and exhaust manifold are flexible metal hoses.
[0015] By adopting the above technical solution, it can withstand greater exhaust force and avoid being flattened and deformed under negative pressure.
[0016] Preferably, the end of the exhaust duct is equipped with a rain cap.
[0017] Preferably, the exhaust fan is installed at the top of the cabinet, and the cabinet and the exhaust fan are connected by a rubber shock-absorbing pad.
[0018] Preferably, the exhaust branch pipes and exhaust manifolds are housed within the pipework interlayer.
[0019] Preferably, the exhaust end of the exhaust duct extends to the outside of the cabinet's front projection.
[0020] Preferably, the inner diameter of the exhaust manifold is 50mm.
[0021] Preferably, the cross-sectional area of the inner diameter of the exhaust manifold is 32% to 49% of the cross-sectional area of the cabinet cavity in the direction of the exhaust manifold.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] The cabinet chambers have individually connected pipes and control valves to avoid mutual interference. Due to the excellent layout of the exhaust ducts, the pipe path is reduced and the exhaust effect is improved. The gap between the cabinet doors is used to achieve rapid air exhaust. At the same time, considering environmental protection, each cavity is equipped with a disinfection device, which purifies the air through the negative ion purification function, avoiding the use of consumables and manual intervention.

[0029] Detailed Implementation
[0030] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0031] like Figure 1 , 2As shown, a takeaway cabinet with a ventilation, sterilization and disinfection system includes a cabinet body with several partitioned chambers. The cabinet body has cabinet doors in front of the corresponding chambers and an insertable sterilization and deodorization device 2 at the rear of the cabinet body. The insertable sterilization and deodorization device 2 includes an exhaust duct 5, an exhaust branch pipe 9 and an exhaust manifold 6. The exhaust duct 5 extends to the top of the cabinet body, and the top of the exhaust duct 5 is connected to an exhaust fan 1 that drives the air in the cabinet chamber to be discharged.
[0032] like Figure 1 , 2 As shown, exhaust branch pipes 9 are connected to exhaust ducts 5 at intervals, and exhaust branch pipes 9 are arranged horizontally in relation to the cabinet. Exhaust manifolds 6 are connected to exhaust branch pipes 9 at intervals, and exhaust manifolds 6 extend and connect to the cabinet chambers in the horizontal row corresponding to exhaust branch pipes 9, thereby realizing the control of several cabinet chambers through a single air source.
[0033] In one variation, the exhaust branch pipe 9 is arranged in the vertical column of the cabinet, and the exhaust manifold 6 extends and connects to the cabinet cavity in the vertical column corresponding to the exhaust branch pipe 9.
[0034] like Figure 1 , 3 As shown, each exhaust manifold 6 is equipped with an electric air valve 4. The electric air valve 4 can independently connect or cut off the air between the exhaust duct 5 and the corresponding cabinet chamber. The electric air valve 4 is normally closed to prevent cross-contamination of food odors between each takeaway cabinet. When the deliveryman delivers the takeaway and when people pick up the takeaway, they will open the takeaway cabinet. At this time, the electric air valve 4 will be interlocked and opened. The exhaust fan 1 and the insertable sterilization and deodorization device 2 will operate in conjunction with the electric air duct. The airflow will flow from the cabinet door to the cabinet and then to the exhaust port inside the takeaway cabinet, and then be discharged outdoors through the exhaust duct. The exhaust fan 1 is installed at the top of the cabinet, and the cabinet and the exhaust fan 1 are connected by a rubber shock-absorbing pad 8, thereby reducing the vibration of the exhaust fan 1 transmitted to the cabinet.
[0035] like Figure 1 , 3 As shown, each cabinet cavity is equipped with a negative ion disinfection device 3 located near the connection point of the exhaust duct 5. The disinfection device releases active negative ions, adsorbs dust, removes odors, and empties the cabinet cavity while preventing the exhaust air from polluting the external environment.
[0036] Preferably, when storing takeout, only one of the cabinet cavities corresponding to the exhaust branch pipe 9 in the same horizontal or vertical row can be opened, and at most one of the electric air valves 4 on the exhaust manifold 6 corresponding to the exhaust branch pipe 9 can be connected, thereby avoiding the simultaneous operation of multiple electric air valves 4 in the same horizontal or vertical row, which would reduce the exhaust effect.
[0037] Preferably, the exhaust duct 5, exhaust branch duct 9, and exhaust manifold 6 are flexible metal hoses, which prevents the pipes from being flattened and deformed under the negative pressure of the exhaust fan 1 and allows them to withstand greater exhaust force.
[0038] like Figure 2 , 3 As shown, a pipe-laying interlayer is provided at the rear of the cabinet. The exhaust duct 5, exhaust branch pipe 9 and exhaust manifold 6 are housed in the pipe-laying interlayer. Since the exhaust duct 5, exhaust branch pipe 9 and exhaust manifold 6 are made of metal, the pipe-laying interlayer can prevent the cabinet from colliding with the pipes during installation, which could cause the pipes to collapse and affect ventilation. It can also prevent animals such as rats from gnawing and damaging them.
[0039] like Figure 1 , 2 As shown, the end of the exhaust duct 5 is equipped with a rain cap 7 to prevent rainwater from flowing back into the exhaust duct when placed outdoors; the exhaust end of the exhaust duct 5 extends to the outside of the cabinet's front projection to prevent the air discharged from the exhaust duct from blowing up the dust covering the top of the cabinet.
[0040] Preferably, the inner diameter of the exhaust manifold 6 is 50mm, and the cross-sectional area of the inner diameter of the exhaust manifold 6 is 32% to 49% of the cross-sectional area of the cabinet cavity in the direction corresponding to the exhaust manifold 6. In this embodiment, the height and width of the cabinet cavity are 20cm*20cm and 20cm*30cm, respectively. Within this range, the diameter of the exhaust manifold 6 will not have excessive redundancy, and the problem of low exhaust efficiency due to excessively narrow diameter can also be avoided.
[0041] The takeaway lockers, through their purification, disinfection, deodorization, and ventilation systems, and their two-stage disinfection and sterilization system, not only ensure the hygiene of the lockers but also reduce bacterial growth, thereby solving the safety issues of takeaway food.
