Description

Technical Field

[0001] The present invention relates to the field of disinfection cabinets, and in particular to a control method and system for a disinfection cabinet which performs high-temperature disinfection and drying on articles in an inner cavity of the disinfection cabinet by heating air, and the disinfection cabinet. Background Art

[0002] Traditional sterilizers often suffer from uneven temperature distribution, high energy consumption, and safety issues during high-temperature sterilization and drying processes. Items requiring high temperature control, particularly maternal and infant products like silicone nipples, teethers, and PP bottles, can easily release harmful substances and even soften and deform when temperatures exceed 110°C. Therefore, these items should not be sterilized in areas with localized overheating. Furthermore, if these items are placed in areas with insufficient temperatures, high-temperature sterilization and adequate drying will not be achieved, leading to bacterial growth during storage and compromising disinfection effectiveness.

[0003] Existing high-temperature sterilizers typically have heaters installed at the bottom or back of the sterilizer. These heaters heat the inner walls of the sterilizer, raising the overall temperature of the sterilizer cavity. For example, the utility model patent with authorization publication number CN222899752U discloses a sterilizer for mothers and infants with antibacterial storage. This uses a heating plate at the bottom of the sterilizer's inner chamber. Consequently, items near the bottom of the sterilizer are susceptible to overheating, releasing harmful substances or softening and deforming. Meanwhile, items at the top of the sterilizer, being away from the heating zone and obscured by items at the bottom, can experience poor heating. To address this issue, the invention patent with authorization publication number CN110302401B discloses a sterilization control device with heaters installed at both the bottom and back of the sterilizer. Compared to a sterilizer structure that only heats at the bottom, the addition of a back heater allows for heating of items at different heights. However, the heating effect on items near the inner walls and in the middle of the sterilizer remains uneven. Furthermore, when heating containers such as baby bottles, the drying effect within the container is often less than ideal.

[0004] To this end, some existing technologies adopt a zoned disinfection method. For example, the invention patent with publication number CN120292833A discloses an external circulation drying structure and tableware cabinet that takes into account multiple cavities. By allocating multiple cavities and setting at least one corresponding sub-duct in each cavity, it ensures that a relatively balanced drying effect is achieved in each cavity. However, this disinfection cabinet structure still has some problems: 1. Although the heating and drying effects in different cavities are relatively balanced, if only one air outlet is set in the same cavity, uneven heating will still occur; 2. In the disinfection cabinet, one cavity must be provided with at least one air duct, so the air duct structure of the disinfection cabinet is complex and the manufacturing cost is high; 3. Since different air ducts use the same drying fan to achieve hot air transportation, due to different transportation distances, the wind force close to the air outlet of the drying fan will be significantly greater than the wind force far away from the air outlet of the drying fan, which also leads to relatively poor drying effect in the cavity far away from the drying fan; 4. The drying fan can only blow out hot air. As the running time of the drying fan increases, the temperature inside the disinfection cabinet gradually increases, and the drying structure does not provide overheating protection function, nor does it provide cold air ventilation and cooling function; at the same time, the drying fan cannot dynamically adjust its wind force or wind speed according to its working mode or working status. In addition, existing high-temperature disinfection cabinets do not provide anti-scalding protection. After high-temperature disinfection, if there is no anti-scalding protection function, users can easily be scalded when taking items out of the disinfection cabinet. Summary of the Invention

[0005] Therefore, in order to solve the above problems, the present invention provides a control method and system for a disinfection cabinet and a disinfection cabinet.

[0006] The present invention is achieved through the following technical solutions: The control method of the disinfection cabinet is based on the operation of a control system, wherein the control system includes at least a controller, an air control module, a heating module, a timing module, a temperature detection module and an indication module. The air control module includes a first air control device arranged at the air inlet and a second air control device at the air outlet, which is used to control the air inlet speed R at the air inlet of the disinfection cabinet. 进 And the wind speed R at the outlet 出 The heating module is used to heat the air inlet and cooperate with the first air control device to generate a hot air flow for high-temperature disinfection and drying of items in the disinfection cabinet cavity. The temperature detection module is used to detect the air inlet temperature W 进 and outlet temperature W 出 ; The control method comprises the following steps: S1: Start the disinfection and drying function according to user instructions; S2: Entering the heating stage, the air inlet speed R 进 Start the first wind speed threshold R1, the wind speed R 出Start the second wind speed threshold R2, when the outlet temperature W 出 After the first temperature threshold W1 is reached for the first time, the heating module is turned off and the process goes to step S3; S3: Enter the constant temperature control stage, set the constant temperature time T1 and the second temperature threshold W2 (W2<W1), the air inlet speed R 进 and air outlet speed R 出 Unchanged, when W 出 When ≤W2, turn on the heating module; when W 出 ≥W1, turn off the heating module; when W 进 When ≤W1, the heating module is turned on again; the disinfection and drying function is completed after the constant temperature time T1 is reached.

[0007] Preferably, in step S2, a first fault determination time T2 is further provided. After step S2 starts, if the air outlet temperature has not reached the first temperature threshold W1 within the first fault determination time T2, the air inlet temperature W is detected. 进 Whether the first temperature threshold W1 is reached; if W 进 ≥W1, it is judged that the internal air path of the disinfection cabinet is faulty, and the air inlet speed R 进 Start the third wind speed threshold R3 (R3>R1); if W 进 If the value is less than W1, it is judged that the heating module is faulty, the red light of the indicator module alarms and the disinfection and drying function is turned off.

[0008] Preferably, in step S2, the second fault determination time T3 is set, when the inlet wind speed R 进 When the third wind speed threshold R3 is activated and the second fault judgment time T3 is reached, the outlet temperature W is detected. 出 , if W 出 ≤W1, the indicator module will light up yellow and the wind speed R 出 The fourth wind speed threshold R4 (R4>R2) is activated.

[0009] Preferably, a temperature difference threshold W0 is set. In step S3, when the air inlet temperature W 进 and outlet temperature W 出 When the temperature difference △W exceeds the temperature difference threshold W0, the wind speed R 出 The fourth wind speed threshold R4 is activated.

[0010] Preferably, set the overheating temperature threshold W max (W max >W1), after starting the disinfection and drying function, when W 进 >W max When the overheat protection is activated, the heating module is turned off until W 进 Restart the heating module after ≤W1.

[0011] Preferably, before step S2, a preheating step S2' is further included: the air inlet speed R 进 Start the preheating wind speed R0 (R0≤R1), turn on the heating module at the same time, and turn off the second wind control device at the air outlet. 出 When ≥W2, go to step S2.

[0012] Preferably, after the disinfection and drying function is started, the disinfection cabinet door is locked; when the disinfection and drying function is completed, the heating module is turned off and the air inlet temperature W is monitored in real time. 进 and outlet temperature W 出 , when W 进 and W 出 After the temperature is less than 40℃, the disinfection cabinet door is unlocked.

[0013] Preferably, the control system of the disinfection cabinet further includes an ultraviolet disinfection module. When the disinfection and drying functions are completed, the ultraviolet disinfection module is turned on and performs ultraviolet disinfection on the inner cavity of the disinfection cabinet until the disinfection cabinet door is unlocked and the ultraviolet disinfection module is synchronously turned off.

[0014] The control system of the disinfection cabinet includes: The wind control module includes a first wind control device at the air inlet and a second wind control device at the air outlet, which is used to control the air speed R at the air inlet of the disinfection cabinet. 进 And the wind speed R at the outlet 出 ; A heating module, comprising a heating device provided at the air inlet, for heating the air inlet and cooperating with the first air control device to generate a hot air flow for high-temperature disinfection and drying of items in the inner cavity of the disinfection cabinet; Timing module, including a timer, used to record working time and fault determination time; The temperature detection module includes a first temperature sensor at the air inlet and a second temperature sensor at the air outlet, which are used to detect the air inlet temperature W 进 and outlet temperature W 出 ; The ultraviolet disinfection module includes an ultraviolet disinfection lamp arranged in the inner cavity of the disinfection cabinet, which is used to perform ultraviolet disinfection on the items in the disinfection cabinet; Indication module, including an operation panel, for displaying the working status and providing function keys for user selection; The controller is respectively connected to the heating module, the timing module, the temperature detection module, the ultraviolet disinfection module and the indication module through electrical signals, and executes the control method of the disinfection cabinet as described above.

[0015] A disinfection cabinet, comprising the control system of the disinfection cabinet as described above.

[0016] The beneficial effects of the technical solution of the present invention are mainly reflected in: 1. The wind control module blows air into the air inlet of the disinfection cabinet to provide positive pressure to the inner cavity of the disinfection cabinet, and actively extracts air at the air outlet to provide negative pressure. The air pressure difference between the inlet and outlet will drive the air in the inner cavity of the disinfection cabinet to spontaneously flow from the high-pressure area to the low-pressure area, thereby forming an efficient forced convection circulation in the inner cavity of the disinfection cabinet to ensure uniform heating and drying throughout the inner cavity of the disinfection cabinet. At the same time, through the linkage control of the wind control module, heating module, timing module and temperature detection module, the heating power, air inlet and outlet wind speeds are dynamically and frequently adjusted to form a stable and uniform heat circulation field in the cabinet, so as to achieve stable, balanced and effective disinfection and drying of items in the disinfection cabinet.

[0017] 2. After starting the disinfection and drying function, the system first enters the heating stage to achieve rapid temperature increase in the disinfection cabinet. Before the heating stage, safe preheating can be performed to accelerate the heating process while ensuring that the heating temperature does not cause overheating. After the heating stage, the system enters the constant temperature control stage and dynamically adjusts multiple parameters (inlet and outlet temperature / wind speed / temperature difference) to ensure that the temperature fluctuation of the disinfection cabinet during the constant temperature control stage is limited to a very small range, thereby improving the disinfection and drying efficiency and ensuring the disinfection and drying effect.

[0018] 3. After starting the disinfection and drying function, the temperature at the air inlet and outlet is monitored in real time, and the timing function is combined to realize the fault judgment of each component. At the same time, customized fault handling methods are adopted for different fault types and fault levels. On the one hand, the faulty components can be accurately located to facilitate subsequent processing and maintenance. On the other hand, automated fault handling can avoid damage to items caused by faults or affect the current disinfection work process.

[0019] 4. During the disinfection and drying control process, you can also set the overheating temperature threshold W max This is to avoid damage to items and release of harmful substances due to overheating inside the disinfection cabinet. At the same time, when the overheating protection takes effect and detects that the temperature environment inside the disinfection cabinet has reached a safe state, it will automatically restart heating, thereby avoiding interruption of the disinfection and drying process due to overheating protection, ensuring the safety of items while ensuring the continuous and effective operation of disinfection and drying work.

[0020] 5. By adding a safety lock function, the disinfection cabinet door is locked during the disinfection and drying process and when the temperature of the disinfection cabinet cavity has not dropped after the disinfection and drying is completed, thereby preventing users from opening the disinfection cabinet door to take items when the temperature of the disinfection cabinet cavity is high and causing burns, which further improves the safety performance of the disinfection cabinet.

[0021] 6. In addition to controlling the hot air flow to disinfect items, the UV disinfection module can also be combined to perform UV disinfection on the inner cavity of the disinfection cabinet. The UV disinfection module and the disinfection and drying function are staggered to avoid the water vapor generated during the drying process blocking the UV light and affecting the UV disinfection effect. At the same time, the cooling and storage time after drying is completed and before unlocking are cleverly used for UV disinfection, thereby maximizing the disinfection efficiency.

DETAILED DESCRIPTION

[0023] To more clearly and in detail illustrate the objectives, advantages, and features of the present invention, the following non-limiting description of preferred embodiments is provided for illustration and explanation. This embodiment is merely a typical example of the application of the technical solution of the present invention. Any technical solution formed by equivalent substitution or equivalent transformation falls within the scope of protection claimed by the present invention.

[0025] Furthermore, the terms "first" and "second" in this solution are used for descriptive purposes only and should not be construed as indicating or implying a ranking of importance or implicitly specifying the number of technical features shown. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0026] The present invention discloses a control method for a disinfection cabinet, such as Figure 9 As shown, the control system operates based on the control system, which includes at least a controller, an air control module, a heating module, a timing module, a temperature detection module and an indication module, wherein the air control module, the heating module, the timing module, the temperature detection module and the indication module are respectively connected to the controller via electrical signals, thereby realizing the communication control of the controller over each module.

[0027] like Figure 5-Figure 8 As shown, the wind control module includes a first wind control device 4 provided at the air inlet 201 and a second wind control device 5 provided at the air outlet 202, which is used to control the air velocity R at the air inlet 201 of the disinfection cabinet. 进 and the wind speed R at the air outlet 202 出 In one embodiment, the first air control device 4 is an exhaust fan arranged at the air inlet 201 of the disinfection cabinet, and the exhaust fan blows external air into the inner cavity 2 of the disinfection cabinet. The second air control device 5 is an exhaust fan arranged at the air outlet 202 of the disinfection cabinet, and the exhaust fan draws the air from the inner cavity 2 of the disinfection cabinet to the outside of the disinfection cabinet. Figure 4 As shown, when the first air control device 4 and the second air control device 5 are turned on at the same time, a high-speed gas circulation is formed in the inner cavity 2 of the disinfection cabinet to ensure that the high-speed flowing gas evenly contacts all parts of the inner cavity 2 of the disinfection cabinet, and ensure that the air flow rate in each area of ​​the inner cavity 2 of the disinfection cabinet is balanced, which facilitates subsequent uniform heating of each area of ​​the disinfection cabinet.

[0028] The heating module is used to heat the air inlet 201 and cooperate with the first air control device 4 to generate a hot air flow for high-temperature disinfection and drying of items in the inner cavity 2 of the disinfection cabinet. The temperature detection module is used to detect the temperature W of the air inlet 201. 进 and the air outlet 202 temperature W 出 Since the first air control device 4 and the second air control device 5 allow the air inside the disinfection cabinet to circulate at a high speed, after the heating module is turned on, the high-speed flowing hot air can not only quickly heat and dry the items, but also ensure that the temperature in all parts of the disinfection cabinet is balanced, and there will be no problems such as local overheating or excessive temperature differences; Figure 4As shown, since the heating module is arranged near the air inlet 201, in order to avoid overheating near the heating module, the wind speed at the air inlet 201 is set to the maximum wind speed. On the one hand, it is beneficial to heat dissipation near the heating module to avoid local overheating. On the other hand, it can ensure that the hot air is blown quickly and evenly to various areas of the inner cavity 2 of the disinfection cabinet to ensure that the temperature of each area of ​​the inner cavity 2 of the disinfection cabinet is balanced.

[0029] The control method of the disinfection cabinet includes the following steps: S1: Start the disinfection and drying function according to user instructions. In some embodiments, the indication module includes an operation panel 11 arranged on the outer surface of the disinfection cabinet. By setting corresponding function buttons on the operation panel 11, it is convenient for the user to choose to start or close the disinfection and drying function and other functions.

[0030] S2: Entering the heating stage, the air inlet speed R 进 Start the first wind speed threshold R1, the wind speed R 出 Start the second wind speed threshold R2, when the air outlet 202 temperature W 出 After reaching the first temperature threshold W1 for the first time, the heating module is turned off and the process goes to step S3. In the heating stage, the temperature of the inner cavity 2 of the disinfection cabinet continues to rise. By strictly controlling the air velocity R 进 and air outlet speed R 出 , which can avoid the problems of local excessive temperature rise and uneven temperature rise; the specific value of the first temperature threshold W1 can be adjusted according to actual needs. In some embodiments, the first temperature threshold W1 suitable for a sterilization cabinet for maternal and infant products is preferably set to 80°C-100°C. When the first temperature threshold W1 is set to 80°C-100°C, it can prevent items made of silicone or PP from releasing toxic substances and softening and deforming, while also ensuring the efficiency and effect of sterilization and drying. In a preferred embodiment, the first temperature threshold W1 of the sterilization cabinet is preferably set to 80°C.

[0031] S3: Enter the constant temperature control stage, set the constant temperature time T1 and the second temperature threshold W2 (W2<W1), the air inlet speed R 进 and air outlet speed R 出 Unchanged, when W 出 When ≤W2, turn on the heating module; when W 出 ≥W1, turn off the heating module; when W 进 When ≤W1, the heating module is turned on again; the disinfection and drying function is completed after the constant temperature time T1 is reached; the temperature W of the air inlet 201 is monitored in real time. 进 and the air outlet 202 temperature W 出, the heating module can be dynamically adjusted to reduce the temperature fluctuation of the inner cavity 2 of the disinfection cabinet while avoiding overheating, thereby achieving efficient drying. The specific value of the second temperature threshold W2 can be adjusted according to actual needs. In some embodiments, the first temperature threshold W1 suitable for the disinfection cabinet for maternal and child products is preferably set to 65℃-80℃. In a preferred embodiment, the first temperature threshold W1 of the disinfection cabinet is preferably set to 65℃.

[0032] In some embodiments, before step S2, a preheating step S2' is further included: the air inlet speed R 进 Start the preheating wind speed R0 (R0≤R1), turn on the heating module at the same time, close the second wind control device 5 at the air outlet 202, when W 出 ≥W2, enter step S2; the preheating step is used to quickly heat the inner cavity 2 of the disinfection cabinet to an effective drying temperature. Rapid heating can effectively improve drying efficiency and save energy.

[0033] In some embodiments, a first fault determination time T2 is further provided in step S2. After step S2 starts, if the temperature of the air outlet 202 has not reached the first temperature threshold W1 within the first fault determination time T2, the temperature of the air inlet 201 is detected. 进 Whether the first temperature threshold W1 is reached; since the completion index of the heating stage is the air inlet 201 temperature W 进 Whether the first temperature threshold W1 is reached, and when some components of the disinfection cabinet fail, the temperature at the air outlet 202 may not reach the first temperature threshold W1. If the heating stage is not timed, then in the case of continuous heating, it is very likely to cause local overheating, resulting in damage to the items or even safety risks, or cause drying failure when the heating module fails; Therefore, after reaching the first fault judgment time T2, the following judgment and processing are performed: If W 进 ≥W1, it is judged that the internal air duct of the disinfection cabinet is faulty. The internal air duct fault may be caused by the air duct being blocked / blocked. To solve the fault, the air inlet speed R 进 Start the third wind speed threshold R3 (R3>R1), by increasing the wind speed R 进 To reduce the impact of wind path obstruction / blockage; if W 进 <W1, it means that the air inlet 201 has not been effectively heated up, so it is judged that the heating module is faulty. Since the heating module cannot operate the disinfection and drying functions normally after being damaged, the red light of the indicator module alarms and the disinfection and drying functions are turned off.

[0034] In some embodiments, in step S2, a second fault determination time T3 is set to further determine the cause of the internal air duct failure of the disinfection cabinet. 进When the third wind speed threshold R3 is activated and the second fault determination time T3 is reached, the temperature W of the air outlet 202 is detected. 出 , if W 出 ≤W1, it means that the internal air duct fault of the disinfection cabinet has not been solved. This may be due to the failure of the first air control device 4 at the air inlet 201 or the obstruction / blockage of the air duct. Therefore, it is necessary to provide a larger internal wind force through the second air control device 5 at the air outlet 202. The yellow light of the indicator module alarms and the air outlet speed R 出 The fourth wind speed threshold R4 (R4>R2) is activated.

[0035] In the above embodiment, the first fault determination time length T2 and the second fault determination time length T3 can be set and flexibly adjusted according to actual needs, and will not be described in detail here.

[0036] In a preferred embodiment, a temperature difference threshold W0 is set. In step S3, when the temperature W 进 and the temperature W at the air outlet 202 出 When the temperature difference △W exceeds the temperature difference threshold W0, the wind speed R 出 The fourth wind speed threshold R4 is started. At this time, the wind speed at the air outlet 202 increases, which can effectively reduce the temperature difference ΔW, thereby ensuring that the overall temperature difference of the disinfection cabinet is not too large, and further reducing the temperature fluctuation of each area of ​​the disinfection cabinet. The temperature difference ΔW is preferably 10℃-15℃.

[0037] like Figure 2 As shown in the figure, the temperature change curve of the air inlet and outlet of the disinfection cabinet when the existing drying control method is adopted, wherein, in the heating stage, the air inlet speed R 进 Start the first wind speed threshold R1, turn on the heating module at the same time, and do not set the second wind control device 5 at the air outlet. 出 ≥W1, it enters the constant temperature control stage; in the constant temperature control stage, when W 出 When ≤W2, turn on the heating module; when W 出 When ≥W1, the heating module is turned off; it can be clearly seen that this single-position temperature control method will inevitably lead to a delay in temperature control at the air inlet, resulting in large differences in temperature changes in various areas, especially the temperature change difference at the air inlet farthest from the air outlet will be more obvious. This drying method will cause the drying effects of various areas of the disinfection cabinet to be obviously uneven, and due to the control delay at the air inlet, the air inlet temperature may be too high, causing damage to nearby items; at the same time, since the second air control device 5 is not provided at the air outlet, high-speed airflow cannot be formed inside the disinfection cabinet, and the slow air flow rate will inevitably lead to the hot air not being evenly distributed in the disinfection cabinet, which further aggravates the problem of uneven disinfection and drying.

[0038] like Figure 3As shown in FIG. 1 , the temperature change curves of the air inlet 201 and the air outlet 202 of the disinfection cabinet when the control method of this embodiment is adopted are shown. The dynamic adjustment of the heating module according to step S3 above makes the temperature fluctuation of each area of ​​the disinfection cabinet smaller. Since the first air control device 4 and the second air control device 5 operate synchronously, the temperature difference between the air inlet 201 and the air outlet 202 of the disinfection cabinet is extremely small. At the same time, the temperature W of the air inlet 201 is controlled in real time during the constant temperature control stage. 进 and the temperature W at the air outlet 202 出 The temperature difference △W and dynamic temperature adjustment further ensure the temperature stability of each area in the disinfection cabinet cavity 2 during the constant temperature control stage.

[0039] In a preferred embodiment, an overheating temperature threshold W is also provided. max (W max >W1), after starting the disinfection and drying function, when W 进 >W max When the overheat protection is activated, the heating module is turned off until W 进 ≤W1, then restart the heating module; where the overheating temperature threshold W max The setting value can be set according to actual needs. For example, since the heating temperature of common silicone pacifiers, teethers or some PP bottles should not exceed 100°C, the overheating temperature threshold W for the sterilizer of maternal and infant products is max It can be set to 100°C. In other embodiments, the overheating temperature threshold of the disinfection cabinet is W max It can be adjusted according to actual needs and will not be described in detail here.

[0040] In one embodiment, a safety lock is provided at the door 3 of the disinfection cabinet, and the safety lock is connected to the controller by electrical signals. After the disinfection and drying function is started, the door 3 of the disinfection cabinet is locked to prevent the user from opening the door 3 of the disinfection cabinet midway and causing safety hazards. When the disinfection and drying function is completed, the heating module is turned off and the temperature W of the air inlet 201 is monitored in real time. 进 and the air outlet 202 temperature W 出 , when W 进 and W 出 After the temperature is both less than 40°C, the disinfection cabinet door 3 is unlocked, and the user will not be burned when taking out items inside the disinfection cabinet.

[0041] In some embodiments, the control system of the disinfection cabinet also includes an ultraviolet disinfection module, and the ultraviolet disinfection module includes a plurality of ultraviolet disinfection lamps 9 evenly distributed in the inner cavity 2 of the disinfection cabinet. The arrangement position of the ultraviolet disinfection lamp 9 can be adjusted according to actual needs. The arrangement position of the ultraviolet disinfection lamp 9 should not be used as a limitation on the scope of protection of the present invention, so it will not be elaborated.

[0042] The ultraviolet disinfection lamp 9 is connected to the controller electrical signal, and the switch is controlled by the controller. After the disinfection and drying function is completed, the ultraviolet disinfection module is turned on and the inner cavity 2 of the disinfection cabinet is disinfected by ultraviolet until the disinfection cabinet door 3 is unlocked and the ultraviolet disinfection module is synchronously turned off, thereby utilizing the cooling time after the disinfection and drying function is completed to further disinfect the items; in addition, when the disinfection cabinet does not turn on the disinfection and drying function, the user can select the ultraviolet disinfection function through the indication module, and the ultraviolet disinfection lamp 9 is used to disinfect the items stored in the inner cavity 2 of the disinfection cabinet; in a preferred embodiment, when the disinfection cabinet runs different functions, the indication module is used for text, mark prompts or different colors of atmosphere lights for prompts, which will not be repeated here.

[0043] The present invention also discloses a control system for a disinfection cabinet, which may specifically include but is not limited to: The wind control module includes a first wind control device 4 at the air inlet 201 and a second wind control device 5 at the air outlet 202, which is used to control the air speed R at the air inlet 201 of the disinfection cabinet. 进 and the wind speed R at the air outlet 202 出 In one embodiment, the first air control device 4 is an exhaust fan provided at the air inlet 201 of the disinfection cabinet, which blows external air into the inner cavity 2 of the disinfection cabinet, and the second air control device 5 is an exhaust fan provided at the air outlet 202 of the disinfection cabinet, which draws air from the inner cavity 2 of the disinfection cabinet to the outside of the disinfection cabinet; The heating module includes a heating device 6 provided at the air inlet 201, which is used to heat the air inlet 201 and cooperate with the first air control device 4 to generate a hot air flow for high-temperature disinfection and drying of items in the inner cavity 2 of the disinfection cabinet; Timing module, including a timer, used to record working time and fault determination time; The temperature detection module includes a first temperature sensor at the air inlet 201 and a second temperature sensor at the air outlet 202, which is used to detect the temperature W of the air inlet 201. 进 and the air outlet 202 temperature W 出 ; The ultraviolet disinfection module includes an ultraviolet disinfection lamp 9 arranged in the inner cavity 2 of the disinfection cabinet, which is used to perform ultraviolet disinfection on the items in the disinfection cabinet.

[0046] like Figure 5-Figure 8 As shown, the present invention also discloses a disinfection cabinet, including the control system of the disinfection cabinet as described above.

[0047] In a preferred embodiment, the disinfection cabinet includes an outer shell 1 and an inner cavity 2 of the disinfection cabinet arranged in the outer shell 1, a disinfection cabinet door 3 for opening or closing the inner cavity 2 of the disinfection cabinet is provided on one side of the outer shell 1, and the indication module includes an operation panel 11 provided on the disinfection cabinet door 3, and a plurality of function buttons and a data display screen are provided on the operation panel 11; the inner cavity 2 of the disinfection cabinet is divided into at least two storage layers by a storage grid 7 and / or a storage basket 8, and an ultraviolet disinfection lamp 9 is arranged on the inner wall of the disinfection cabinet corresponding to each storage layer.
