In this embodiment, when the water vapor shutoff device is disposed inside the first housing. In the process of circulating the hot air, the water vapor intercepting device can intercept water vapor in the hot air which flows circularly; meanwhile, as the water vapor cut-off device is arranged inside the first shell, the space inside the first shell can be effectively utilized, and the situation that more milk bottles and other structures cannot be placed due to the fact that the space inside the sterilizer occupies too much when the water vapor cut-off device is arranged inside the sterilizer is avoided. It should be noted that the water vapor shut-off device itself may be arranged in the region between the first housing and the second housing, or may be arranged inside the second housing.

The position of zone of heating is provided with heating plate 5, realizes the heating operation to kettle 7 after heating plate 5 starts, is provided with the controller simultaneously on warm milk sterilizer, and the controller self has the function of adjusting the temperature, rising temperature and accuse temperature, can realize rising to 100 ℃ with the temperature, perhaps stabilizes the temperature at 45 ℃, 50 ℃ etc. can directly be used for the temperature of dashing milk.

The working process of the milk warming sterilizer provided in the present embodiment is as follows, as shown in fig. 10:

firstly, a certain amount of clean water is put into the water containing tray 4, the control device is started, the hot air generating device 3 is started, the heating body 305 and the impeller 306 inside the hot air generating device 3 are started, air inside the hot air generating device 3 is heated, and cold air is sucked from the second air inlet 301 and then flows out from the second air outlet 302 and further flows into the sterilizer 2.

And (3) disinfection procedure:

when the temperature sensing bulb detects that the temperature inside the sterilizer rises to 40 ℃, the heating plate 5 is controlled to be started, the heating plate 5 heats the water inside the water containing plate 4 and forms water vapor, and the temperature inside the sterilizer rises rapidly at the moment. Meanwhile, as the hot air generating device 3 continuously introduces the water vapor into the interior of the sterilizer for heating, the water vapor is heated for the second time to form superheated steam (the temperature is more than 100 ℃), the integral temperature of the sterilizer is higher than 100 ℃, the steam lasts for 15 minutes, and the standard of the sterilizer in one star is achieved.

After the heating plate 5 is started, because it takes a period of time for the water to be heated from normal temperature to be boiled to generate steam, the water cannot be directly converted into steam, auxiliary heating can be performed through the hot air generating device 3 in the period of time, and the temperature in the sterilizer is raised to about 55 ℃. After a period of time, the water is boiled and the sterilizer 2 is heated by the steam, at which point a rapid temperature rise phase is initiated. The steam is heated secondarily by the hot air generator 3 to form superheated steam with a temperature exceeding 100 ℃. After about 5 minutes of heating, the sterilizer temperature exceeded 100 ℃ for 15 minutes, which reached the one-star standard for a sterilizer, for a total of about 23 minutes. Compare prior art, singly use the dish that generates heat and produce steam, the temperature can't reach 100 ℃, and the disinfection time is also less than 15 minutes, and the effect of the disinfection procedure that this embodiment provided is more showing.

And (3) disinfection procedure:

after the disinfection is finished, the heating plate 5 stops working, the hot air generating device 3 is continuously opened, at the high temperature, condensed water in the disinfector can be naturally evaporated, the temperature in the disinfector slowly reduces along with the time, and finally the temperature is stabilized at about 70 ℃. Because the condensed water in the sterilizer 2 and the feeding bottle inside the sterilizer is naturally evaporated in a high-temperature environment, the whole sterilization cavity is in a positive pressure state, and although the steam outlet is directly communicated with the outside and overflows from the steam outlet of the upper cover of the sterilizer, the outside air cannot enter to cause pollution. After a period of time, the sterilizer is completely dry.

After a period of time, the sterilizer 2 and the feeding bottle are thoroughly dried, and the drying process is completed. Then, enter a custody program: the hot air generating device 3 works for 1 minute every 5 minutes, and the inside of the sterilizer 2 and the feeding bottle are kept dry, so that bacteria are prevented from breeding.

It should be noted that, the time and the temperature involved in the above working process may be adjusted according to different working conditions, and are not mentioned here.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
