Safe drying methods for sterilizers and sterilizers

Abstract

The invention discloses a sterilizer and a safe drying method for a sterilizer. Wherein, the safe drying method includes the steps of: the fan runs slowly to the first preset speed V1 within the first preset time length T1; determines the second preset speed V2 of the fan for subsequent hot air drying; PTC The heating element is powered and heated to heat the airflow blown by the fan into a hot airflow. At the same time, the fan runs at the second preset speed V2 to form hot air and blow it into the disinfection chamber for hot air drying. V1≤V2≤V0, V0 is the temperature of the fan Rated speed; the PTC heating element stops heating when it is powered off, and the fan continues to run for the third preset time T3 and then stops. Let the fan and PTC heating element be controlled separately, the fan adopts slow start and provides adjustable speed, only in the middle of the drying process, the PTC heating element is allowed to work, which improves the safety of use and the service life of the fan, and improves the user's use experience.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a sterilizer and a safe drying method for a sterilizer. Background technique [0002] This section only provides background information related to the application to facilitate those skilled in the art to understand the application more thoroughly and accurately, and it is not necessarily the prior art. [0003] The main sterilization methods existing in the field of household appliances are high temperature, ultraviolet rays or ozone, each of which has advantages and disadvantages and has different usage occasions. [0004] Take the existing baby bottle sterilizer or sterilizer on the market as an example, which generally have the functions of high-temperature disinfection and drying. The drying generally uses a fan and a heating element to work at the same time, and blows out high-temperature hot air to dry the inside of the baby bottle or the sterilized product. ...

AI Technical Summary

Problems solved by technology

Existing feeding bottle sterilizers generally only have a fixed wind speed gear, and users cannot select the gear according to their own needs; in addition, due to the non-independent control of the fan and the PTC heating element in the drying operation of the prior art, the two Either work at the same time or stop at the same time. After the drying operation is over, the disinfection chamber is in a high temperature state when the user opens the sterilizer, which is easy to burn the user, and there is a certain danger; similar problems exist in disinfection. After the disinfection is completed, the user opens the sterilizer. The disinfection chamber is in a high temperature state when the pot is in the pot, and the steam is easy to scald the user, posing a potential safety risk

[0005] For example, the Chinese patent application CN2019108596966 discloses a drying control method for an intelligent baby bottle disinfection dryer, which drives the drying device to run intermittently by controlling the intermittent operation of the motor, providing time for the steam to discharge the cache to prevent the steam from blowing out. This requires frequent start and stop of the motor, which not only consumes electric energy and affects the service life of the motor, but also has the defect of low disinfection and drying efficiency
