Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a sterilization / drying machine for a baby bottle that can be sterilized and dried for the next use in a state where a nipple portion is removed from the bottle mouth of a separately washed baby bottle.
[0002]
[Prior art]
In a neonatal room at a maternity hospital or an infant room at a nursery school, it is necessary to appropriately sterilize a large number of washed baby bottles.
[0003]
Most typically, such baby bottles are sterilized by boiling or by immersing the baby bottle in a drug for a period of time. However, sterilization of baby bottles by boiling or soaking in chemicals requires a considerable amount of time, and requires additional drying after sterilization and special consideration for storage in a clean state after sterilization. Met.
[0004]
In view of the above, there is provided a storage for baby bottles that can store a plurality of baby bottles and has a storage chamber that can heat and store the baby bottles that are stored inside. In addition, in such a storage, a germicidal lamp for irradiating ultraviolet rays is arranged in the storage room, and the baby bottles stored in the storage room are irradiated with ultraviolet rays to simultaneously sterilize the baby bottles. is there.
[0005]
[Problems to be solved by the invention]
In such a storage, the bottle with the nipple part removed is placed in the storage room in a standing state with the bottle mouth up, and the bottle is placed in the storage room in the standing state with the bottle mouth down. There are things. In either case, a germicidal lamp is provided in the upper part of the storage room so that the ultraviolet light is irradiated from above the baby bottle.
[0006]
However, the former type has a disadvantage that the water accompanying the cleaning performed in advance is accumulated at the bottom of the baby bottle and the inside of the baby bottle is difficult to dry properly.
[0007]
In the latter type, the water accompanying the washing can flow down from the inside of the baby bottle, but the air inside the baby bottle is difficult to escape to the outside through the bottle mouth. The inside of the baby bottle could not be dried. In this latter type, it is difficult to properly sterilize the inside of the baby bottle because it is not possible to irradiate the inside of the baby bottle with ultraviolet rays.
[0008]
Accordingly, the main object of the present invention is to enable pre-cleaned baby bottles to be appropriately and efficiently dried and sterilized inside and outside, regardless of the number of baby bottles.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, the bottle sterilizer / dryer is placed in a standing state in which the bottle with the nipple portion removed from the bottle mouth is in the upright state, and through the bottle mouth. A bucket for storing the air in the baby bottle in a state capable of flowing out of the bucket; and a main body having an air inflow portion at an upper portion and a storage chamber for the bucket having an air outflow portion at a lower portion. The main body is stored in a heating air supply means for blowing heated air into the storage chamber from the upper part of the storage chamber, and in a bucket which is outside the lower part of the storage chamber and stored in the storage chamber. The baby bottle is provided with a germicidal lamp for irradiating ultraviolet rays from below.
[0010]
According to this configuration, the pre-cleaned baby bottle is stored in the bucket in an upright state and stored in the storage chamber, so that the water remaining in the baby bottle can flow down to the outside through the bucket. The baby bottle can be more easily dried.
[0011]
Further, the baby bottle stored in the bucket in a standing state can be heated and sterilized and dried by the heated air sent into the storage chamber. In such a bucket, the baby bottle is stored in a standing state with the bottle mouth down, and such heated air is sent from the bottom side of the baby bottle toward the bottle mouth side. Air inside the baby bottle, which is negatively pressurized on the bottle mouth side of the bottle and expanded by heating, flows out from the air outlet of the storage chamber through the bucket as appropriate from the bottle mouth side. As a result, air containing moisture does not stay in the inside of the baby bottle, and not only the outside of the baby bottle but also the inside of the baby bottle can be appropriately dried. The heated air is preferably supplied to the storage room so that the atmospheric temperature of the storage room is maintained at 60 degrees Celsius or higher, more preferably 75 degrees Celsius or higher. This is because bacteria, viruses, and molds are found to grow at a temperature of 5 to 47 degrees Celsius in the presence of moisture and nutrients.
[0012]
Further, the germicidal lamp can irradiate the baby bottle stored in the bucket with ultraviolet rays from the bottle mouth side. Thereby, not only the outside of the baby bottle but also the inside of the baby bottle can be sterilized by ultraviolet rays.
