Description
Technical Field
[0001] The utility model relates to the technical field of disinfection cabinets, in particular to a disinfection cabinet with a hot air system. Background Art
[0002] Existing disinfection cabinets typically incorporate a heating device within the inner chamber for high-temperature disinfection. However, this inner chamber is equipped with a pull-out basket, which holds items to be disinfected. This results in higher temperatures near the heating device, far exceeding the required disinfection standard, while temperatures farther from the heating device are lower, failing to meet the required disinfection standard. Typically, the heating device is installed inside the inner chamber, resulting in lower temperatures near the cabinet door, failing to meet disinfection standards. Therefore, disinfection cabinets are typically divided into two chambers with different disinfection levels, reducing the volume of the chamber to accommodate the heating device and achieve disinfection standards.

[0006] The internal circulation flow channel of the utility model can make the temperature of the inner cavity of the disinfection liner basically consistent. At the same time, the fan is in the external circulation air duct with lower temperature, ensuring the service life of the fan. The fan does not affect the use and installation of the disinfection liner pull-out basket, avoiding the fan reducing the disinfection effect.
[0007] Furthermore, the first heating device is arranged in front of the air outlet, and the fan blows the air flow horizontally toward the first heating device.

The fan does not affect the use and installation of the disinfection liner pull-out basket, and prevents the fan from reducing the disinfection effect of the disinfection lamp. The disinfection liner is easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0033] Example 1, see Figure 1-3 As shown, a disinfection cabinet with a hot air system includes a housing 1 and a disinfection liner 2 disposed within the housing 1. A first heating device 5 is disposed within the disinfection liner 2. A mounting cavity 11 is formed between the back of the disinfection liner 2 and the housing 1. An air duct cover 3 is disposed within the mounting cavity 11. The air duct cover 3 has an open front and is sealed against the back of the disinfection liner 2. An external circulation air duct 30 is disposed between the air duct cover 3 and the disinfection liner 2. Preferably, the first heating device 5 is a heat pipe or a light wave tube.
[0034] In this embodiment, a fan 4 is provided at the bottom of the outer circulation air duct 30. The back of the air duct cover 3 is tilted backward from top to bottom, so that the width of the outer circulation air duct 30 corresponding to the area above the fan 4 gradually decreases from bottom to top.
[0035] An air outlet 21 is provided at the bottom of the back of the sterilization liner 2, corresponding to the bottom of the external circulation air duct 30. An air inlet 22 is provided at the middle of the back of the sterilization liner 2, corresponding to the top of the external circulation air duct 30. A fan 4 blows the airflow in the external circulation air duct 30 into the sterilization liner 2. The airflow in the sterilization liner 2 is then sucked into the external circulation air duct 30 through the air inlet 22, forming an internal circulation flow channel 20 within the sterilization liner 2.
[0036] A first cover body 6 is provided in the disinfection liner 2 in front of the air outlet 21. A first heating device 5 is fixed in the first cover body 6 and is placed at the air outlet 21. A first through hole 61 is provided on the front of the first cover body 6, and a second through hole 62 is provided on the top surface of the first cover body 6. Preferably, the aperture of the first through hole 61 is larger than the aperture of the second through hole 62. An air guide plate 63 is bent upward on the back of the first cover body 6 to form an opening, and the opening of the first cover body 6 faces the air outlet 21. The air guide plate 63 guides the airflow out of the air outlet 21 into the first cover body 6.
[0037] A disinfection lamp 7 is provided on the top of the disinfection liner 2. Preferably, the disinfection lamp 7 is an ultraviolet disinfection lamp 7.
[0038] When the disinfection cabinet is in operation, the disinfection lamp 7 is turned on. At the same time, the fan 4 blows the airflow in the outer circulation duct 30 horizontally toward the first heating device 5. The first heating device 5 heats the airflow. The heat-carrying airflow is divided into two paths through the first cover 6. One path flows through the front of the first through hole 61 to the cabinet door of the shell 1, and the other path flows upward through the second through hole 62. Then, both paths of air flow upward to the top of the disinfection liner 2. The airflow cools and then settles to the middle and rear part of the disinfection liner 2 and is sucked into the air inlet 22 to form the inner circulation flow channel 20. The overall temperature of the disinfection liner 2 is relatively consistent, meeting the national standard GB17988. The airflow in the outer circulation duct 30 and the air inlet 22 to the fan 4 gradually slows down.
[0039] Example 2, see Figure 4-6 As shown, the difference from the first embodiment is that a second heating device 8 is provided in the disinfection liner 2, and the second heating device 8 is arranged at the air inlet 22. Preferably, a second cover body 9 is provided in the disinfection liner 2 corresponding to the air inlet 22, and the second heating device 8 is fixed in the second cover body 9. The front and top surfaces of the second cover body 9 are provided with a plurality of through holes 91, and the bottom of the second cover body 9 is open. The second heating device 8 heats the disinfection liner 2 and the air flow flowing through the air inlet 22. Preferably, the second heating device 8 is a heating tube or a light wave tube. A windshield 92 is provided on the back of the second cover body 9 facing the air inlet 22. The windshield 92 prevents the air flow heated by the second cover body 9 from directly entering the external circulation air duct 30.
[0040] When the airflow in the disinfection liner 2 reaches the air inlet 22, the temperature is low, that is, the temperature of the disinfection liner 2 near the air inlet 22 is low. The second heating device 8 can ensure that the temperature near the air inlet 22 is increased, thereby further making the overall temperature of the disinfection liner 2 relatively consistent, avoiding the existence of sterilization dead corners.
