Description

Technical Field

[0001] The present invention relates to the technical field of cleaning and disinfecting equipment for early childhood educational toys, and in particular to a cleaning and disinfecting machine suitable for early childhood educational toys. The machine can also be used for cleaning and disinfecting medium- and low-risk items in medical institutions. Background Art

[0002] In order to cultivate children's sensory cognition of spatial structure, color and sound, and at the same time improve their thinking, hands-on and expression abilities, childcare institutions in various places are equipped with many types of toys for children to learn while playing and play while learning, laying a solid foundation for their future in-depth learning. At the same time, as children play with toys at a high frequency and high turnover rate, the surface of the toys will inevitably be sticky with sweat and bacteria and viruses from the hands of different children. Coupled with the dust in the attached environment, a large number of bacteria and viruses will often grow on the surface of the toys. Especially during epidemics of infectious diseases, toys often become an important medium for virus transmission in kindergartens.

[0003] To protect the health of young children, my country's current "Nursery and Kindergarten Health Care Work Standards" has made strict regulations on kindergarten health care work. The appendix "Preventive Disinfection Methods for Child Care Institution Environment and Articles" clearly stipulates that toys must be "disinfected with sodium hypochlorite disinfectants. The concentration used is 100-250 mg / L of effective chlorine, wipe the surface, and soak for disinfection for 10-30 minutes. Depending on the pollution situation, disinfection should be carried out at least once a week." When infectious diseases are prevalent, cleaning and disinfection are required once a day. However, there is currently no special cleaning and disinfection equipment for early childhood educational toys in China that meets the requirements of the above regulations, including publicly authorized related toy cleaning and disinfection patent products, such as "A fully automatic plastic toy building block particle cleaning device" with application number 201711411323.X, "A toy drum disinfection machine" with application number 201720975862.5, and "A cleaning and disinfection machine for children's toys" with application number 202322901778.7. None of them meet the statutory cleaning and disinfection requirements for early childhood educational toys. Therefore, kindergartens across the country now generally use manual methods to clean and disinfect toys. Manual cleaning and disinfection generally have three major defects: first, the labor intensity is high and the work efficiency is low; second, the quality of cleaning and disinfection is affected by the operating skills and professional ethics of the cleaning staff and is difficult to guarantee; third, the disinfection process and effect are difficult to monitor effectively. As a result, the cleaning and disinfection of kindergarten toys has fallen into the dilemma of "high standard requirements" and "low technical support", which seriously restricts the implementation of preschool education hygiene standards. It is urgent to establish a "precision control-standardized process-digital monitoring" technical system through the research and development and production of special cleaning and disinfection equipment for preschool education toys, to help effectively implement preschool education health care regulations and protect the health of young children.

[0049] Disinfectant stock solution dilution: The control module of the electrical control box 10 simultaneously opens the disinfectant stock solution control valve 35 and the disinfectant stock solution flowmeter 36. Under the action of gravitational potential energy, the disinfectant stock solution flows from the disinfectant stock solution tank 12, through the disinfectant stock solution control valve 35 and the disinfectant stock solution flowmeter 36, into the reservoir inlet pipe 22, and then flows down the reservoir inlet pipe 22 into the reservoir 7. The corresponding path is shown in the disinfectant stock solution flow direction 41. After the disinfectant stock solution flow rate reaches the system-set threshold, the disinfectant stock solution control valve 35 and the detergent stock solution flowmeter 36 are immediately closed. At the same time, the system opens the clean water control valve 24 and the clean water flowmeter 25. External clean water flows into the reservoir inlet pipe 22 and then flows down the reservoir inlet pipe 22 into the reservoir 7. The corresponding path is shown in the clean water flow direction 43. After the input clean water flow rate reaches the system-set threshold, the clean water control valve 24 and the clean water flowmeter 25 are simultaneously closed, completing the disinfectant stock solution dilution operation.

[0050] Disinfectant circulation disinfection: The control module of the electrical control box 10 simultaneously turns on the circulating spray pump 14, the infusion control valve 27, the rotary spray arm control valve 29, and the ultrasonic cleaning and disinfection tank control valve 30. The disinfectant in the liquid storage tank 7 enters from the inlet of the pipette 26, flows through the circulating filter 13, the circulating spray pump 14, the infusion control valve 27, the infusion tube 28, the rotary spray arm control valve 29, and the ultrasonic cleaning and disinfection tank control valve 30, and enters the rotary spray arm 16 and the ultrasonic cleaning and disinfection tank 18 for disinfection with the disinfectant; the rotary spray arm 16 sprays the disinfectant onto the toys in the carrier 19 or the rotary net bucket 17 while rotating. At the same time, the disinfectant continuously falls to the bottom of the cabin under the action of gravity and gathers into the liquid storage tank 7; when the ultrasonic cleaning and disinfection tank 18 is performing the immersion disinfection operation, the ultrasonic cleaning and disinfection tank discharge control valve 31 remains closed. After the immersion disinfection is completed, the system opens the ultrasonic cleaning and disinfection tank discharge control valve 31, and the disinfectant flows into the liquid storage tank 7 under the action of gravity; the corresponding path of the disinfectant flow is shown in the disinfectant flow direction 42; according to the system setting, this cycle is repeated, and the duration reaches the disinfection time requirement specified in the "Preventive Disinfection Method for Environment and Articles of Child Care Institutions" (for example, 10 to 30 minutes), and the cyclic disinfection operation can be completed.

[0051] Discharge of disinfectant waste liquid: After completing the above-mentioned toy disinfection, the system simultaneously starts the drainage pump 15 and the drainage control valve 34, and the disinfectant waste liquid in the liquid storage tank 7 is discharged outside the machine and enters the external drainage network; the corresponding path is shown in the disinfectant flow direction 42.

[0052] Rinse with clean water to remove the residual disinfectant: To remove the residual disinfectant, the toys need to be rinsed with clean water after disinfection. The specific process is the same as the process of rinsing with clean water to remove the residual detergent.

[0053] Hot air dehumidification and drying: After completing the operation of flushing the disinfectant residue with clean water, the system immediately starts the electric blower 8 and the one-way exhaust vent 9 to dehumidify and dry the water adsorbed or attached to the toys. During this period, the rotating net barrel 17 keeps rotating at a low speed; when the system shows that the humidity in the cleaning and disinfection chamber drops to the set threshold to ensure the drying of the toys, the system turns off the electric blower 8 and the one-way exhaust vent 9 to complete the dehumidification and drying operation; at this point, the cleaning and disinfection operation of a single batch of toys is completed.
