Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a baby bottle sterilizer, and more particularly to a baby bottle sterilizer for sterilizing baby bottles and their attached nipples and nipple caps using steam.

In general, compared to baby bottles, nipple caps aside, nipples are made of materials that are more susceptible to heat, and therefore, when steam sterilizing baby bottles and nipples, they must be sterilized under different conditions. For example, as shown in FIG. 1, a baby bottle 7 and a nipple cap 9 are housed in an inner case 4 provided directly above a steam generating section 3 heated by a heater 2, and the inner case 4 is covered. By storing the nipple 8 in a small chamber 6 provided at the upper bottom of the outer case 5, the baby bottle 7 and the nipple 8 are isolated in the disinfection chamber 1, and the amount of heat applied to the nipple 8 is transferred to the baby bottle 7 and the nipple cap 9. However, this poses a problem in that the nipple 8 must be taken in and out separately from the baby bottle 7 and the nipple cap 9, making handling time-consuming.

The present invention has been made in view of the above points, and its main purpose is to allow baby bottles, nipples, and nipple caps to be taken in and out of the sterilization room all at once, To provide a baby bottle sterilizer capable of simultaneously sterilizing a nipple molded from a heat-sensitive material by changing the amount of steam supplied to the nipple and the nipple molded from a heat-sensitive material, respectively, at temperatures suitable for each.

The present invention will be described in detail below based on embodiments shown in the figures. In this embodiment, in addition to a disinfection chamber 1 for disinfecting a baby bottle 7 and its attached nipple 8 and nipple cap 9 with steam, a hot water storage pot 31 for storing high temperature hot water and milk is provided in one housing A. A hot water chamber 30 for storing the water and keeping it at a relatively low temperature
The disinfection chamber 1 and the boiling water chamber 30 are both formed into a cylindrical shape with an open top and a closed bottom. A steam generating means B for generating steam for sterilizing the baby bottles 7, nipples 8, and nipple caps 9 housed in the disinfection chamber 1 is installed at the bottom of the disinfection chamber 1. A heat-retaining heater 42 is provided to reduce the temperature of high-temperature hot water or milk filled in the hot-water storage pot 31 by cooling it naturally, and to keep it at a predetermined low temperature. The baby bottle 7, the nipple 8, and the nipple cap 9 are held in a stand 10 that is removably housed in the disinfection chamber 3, and when the stand 10 is placed in the disinfection chamber 1, the lid plate 11 of the stand 10 is filled with disinfectant solution. The upper opening of No. 1 is closed. That is, the stand 10 is formed into a shape in which a lid plate 11 and a bottom plate 13 are connected to each other at both the upper and lower ends of a vertical wall 12, and when the stand 10 is housed in the disinfection chamber 1, the lid plate 11 closes the top opening of the disinfection chamber 1. At the same time, the inside of the disinfection chamber 1 is partitioned into two chambers, left and right, by a vertical wall 12, and the baby bottle 7 is stored in one chamber, and the nipple 8 and nipple cap 9 are stored in the other chamber. are two upper and lower holding frames 1 placed on one half of the bottom plate 13 and protruding from one side of the vertical wall 12.
The nipple 8 and nipple cap 9 are held on the stand 10 by fitting into a ring hanger 14 provided on the other side of the vertical wall 12, and the nipple 8 and the nipple cap 9 are held on the stand 10 at the upper surface of the lid plate 11. By holding the handle 18 protruding from the stand 10 to take it in and out, the baby bottle 7 and its attached nipple 8 and nipple cap 9 can be taken in and out of the sterilization room 1 all at once, making it easy to handle. . Further, the housing A is carried by using handles 19 whose both ends are pivoted to the upper ends of the peripheral wall surrounding the disinfection chamber 1. The steam generating means B includes an inner cylinder 21 that protrudes upward from approximately the center of a water tray 20 disposed over substantially the entire bottom of the disinfection chamber 1, a heater 22 housed in the inner cylinder 21, and an inner cylinder 21. It is composed of an outer cylinder 23 to cover and a water absorbent body 24 held between the outer cylinder 23 and the inner cylinder 21, and the water in the water tray 20 is sucked up to the water absorbent body 24 from the suction port at the bottom of the outer cylinder 23. In this case, the water in the water absorbing body 24 is converted into steam by the heat of the inner cylinder 21 formed of a heat conductive plate heated by the heater 22, and this steam is passed through a number of steam blowing holes provided in the peripheral wall of the outer cylinder 23. 26 into the sterilization chamber 1 to sterilize the baby bottles 7, nipples 8, and nipple caps 9, and there is a steam escape hole in the sterilization chamber 1 to prevent steam pressure from rising above a specified level. (not shown) is provided. As the water absorbing body 24, heat-resistant glass wool, asbestos, foamed metal, unglazed material, or the like is used. As shown in FIGS. 3 and 4, this steam generating means B, which is composed of a heater 22, an inner tube 21, a water absorbing body 24, and an outer tube 23, protrudes approximately at the center of the bottom of the disinfection chamber 1, and is attached to the stand 10. The baby bottle 7 is stored in a notch 17 at the bottom of the vertical wall 12, and steam is blown out from the steam blowing hole 26 into two chambers separated by the vertical wall 12. The baby bottle 7 is stored in one chamber, and the nipple 8 and nipple are stored in the other chamber. Cap 9 is disinfected at the same time. By the way, the nipple 8 and the nipple cap 9 are usually made of a material that is less resistant to heat than the baby bottle 7, and therefore, both cannot be steam sterilized under the same conditions. , as shown in FIG.
The total opening area of the steam outlet 26 that opens into the other compartment that accommodates the nipple 8 and nipple cap 9 is made smaller than the total opening area of the steam outlet 26 that opens into the compartment that accommodates the nipple 8 and the nipple cap 9, so that the latter is smaller than the former compartment. The setting is such that the amount of steam flowing into the compartment is small, and therefore, the baby bottle 7, nipple 8, and nipple cap 9 are held together on the stand 10 and housed in the sterilization room 1. Hey, baby bottle 7
Nipple 8 and nipple cap 9 with inferior heat resistance than
can be sterilized at the same time as the baby bottle 7 at a temperature suitable for these.
This has the advantage that it is not necessary to separate the teat and nipple 8 and store them in a sterilization room, making handling easier.

The heater 22 is energized by turning on the main switch 27 provided in a part of the housing A and also turning on the disinfection switch 28, and the entire amount of water in the water tray 20 is changed to steam. After that, a temperature sensor 43 installed on the back side of the water tray 20 detects a sudden rise in the temperature of the water tray 20, and the power to the heater 22 is cut off. As the temperature decreases, the baby bottle 7, nipple 8, and nipple cap 9 become dry and are stored in the disinfection room 1. The hot water storage pot 31 is housed in a hot water chamber 30 formed in one housing A adjacent to the disinfection chamber 1, and the hot water chamber 30 is divided into two chambers 3.
0a and 30b are formed, each with a hot water storage pot 31.
a and 31b are stored. Each hot water storage pot 31a,
31b is filled with boiling water, and the boiling water in each hot water storage pot 31a, 31b melts the powdered milk using the steam condensation water sent from the disinfection room 1, which is a relatively high-temperature formula water (50 to 60°C). After cooling the formula milk dissolved in Tokonoyu to Samashiyu (25-35℃), which is prepared to bring the milk to a temperature suitable for breastfeeding infants,
Each hot water chamber 30a, 30b is kept at its respective temperature by a heat insulating heater 42 provided at the inner bottom. Here, the heater 22 of the steam generating means B and the heat retaining heaters 42 are energized by turning on the main switch 27 provided on the side of the housing A, and then turning on the steam switch 28 and the heat retaining switch 29 on both sides, respectively. Both heaters 22 and 42 are designed so that their respective temperatures do not rise above a set temperature using a temperature detector. Disinfection room 1 and each hot water room 30a, 30
b is separated by a metal condensation plate, and the condensed water generated by condensation of steam generated in the disinfection chamber 1 on the surface of this condensation plate 35 flows from the receiving groove 36 at the lower end of the condensation plate 35 to the gutter 37. Through each hot water room 30a,
The condensed water is collected in a cooling tray 38 provided at the inner bottom of the hot water storage pot 31a, 31b.
It is now used as cooling water. That is, in each hot water chamber 30a, 30b, a bottomed cylindrical cooling wall 40 made of metal is housed with its outer bottom surface placed on a cooling tray 38, and the back surface of the cooling wall 40 is placed on a cooling tray 38. 4 with Frotzky processing
1 is attached, the condensed water that accumulates in the cooling tray 38 is adsorbed to the wick 41, and the latent heat of the condensed water that evaporates from the wick 41 on the back side of the cooling wall 40 removes heat from the cooling wall 40, and the cooling is done. The temperature of the hot water and milk in each of the hot water storage pots 31a and 31b, which are housed with their outer circumferential surfaces in close contact with the inner surface of the wall 40, is lowered.
