The elevating nozzle 70 rises by the water pressure supplied to the vertical pipe 73, and when the water pressure is lost, it descends by its own weight or the load of the weight 72. As the steel ball B is coupled to the groove-shaped guide rail 73a, the elevating nozzle 70 ascends and descends while rotating spirally during elevation. Therefore, the elevating nozzle 70 is sprayed while rotating the washing water sprayed from the nozzle hole 75h. Thus, every corner of the baby bottle is smoothly washed.

The elevating nozzle 70 may have vortex blades 75a on an outer circumferential surface of the head 75 as shown. The vortex blades 75a are rotated when the vertical pipe 73 is raised and lowered to form a vortex in the washing water stored in the washing tub 10. Thus, the inside of the baby bottle is more smoothly cleaned.

The embodiment of the present invention configured as described above is operated in the process of preliminary washing → basic washing → whirlpool washing → heating sterilization → drying, by opening the drain pipe (D) with the control valve (DV) of the drain during the preliminary washing and basic washing Continuously, washing is performed while draining the washing water in the washing tank 10, and washing and sterilization are performed while storing washing water in the washing tank 10 during vortex washing and/or heating sterilization. And, the difference between the preliminary washing and the basic washing is that only the number of spraying water jets is configured differently. That is, the basic washing is configured to have a greater number of injections than the primary washing. For example, the basic washing is composed of 10 times at 2 second intervals when the number of injections of the prime washing is 5 times at 2 second intervals.

First, referring to the preliminary washing, as shown in FIGS. 11 and 15 , hot water from the second washing water tank W2 is supplied to the lower part of the valve housing 21 constituting the distributor. From the distributor, hot water is first supplied to the upper sub-nozzle pipe 5a or the lower sub-nozzle pipe 6a of the sub-washing unit 20 by rotating the multi-way valve 23 of the valve housing 21. At this time, the controller of the controller (not shown) rotates the multi-way valve 23 to the set position as the cam CM provided in the valve housing 21 operates the micro limit switch LS. That is, the control unit can check the rotation angle of the multi-way valve 23 by the operation signal of the micro limit switch LS, which is operated by pressing the cam CM among the micro limit switches LS. The directional valve 23 can be rotated to the normal position. Accordingly, in the multi-way valve 23, the valve hole 23h is connected to the port 21h of the valve housing 21 corresponding to the upper sub-nozzle pipe 5a or the lower sub-nozzle pipe 6a by a fixed position operation. coincide Therefore, hot water is supplied to the upper sub-nozzle pipe 5a or the lower sub-nozzle pipe 6a of the sub-cleaning unit 20 .

The sub-cleaning unit 20 sprays water jets through the second nozzles N to clean nipples (not shown) provided in the cage-type tray CG. The sub cleaning unit 20 cleans the inside and outside of the nipple by spraying water jets to the top and bottom of the nipple through the nozzles N of the upper sub-nozzle tube 5a or the lower sub-nozzle tube 6a.

Then, when the teat washing is completed, the multi-way valve 23 is rotated again in the above-described manner for washing the baby bottle to supply hot water to the main nozzle pipe 43 of the main washing part 40. The main nozzle pipe 43 injects a water jet through a plurality of first nozzles Na. The main nozzle pipe 43 supplies washing water to only one or two of the first nozzles NA by the rotating distribution valve 47 to spray water jets. That is, the main nozzle pipe 43 supplies washing water only to the first nozzle Na at which the discharge orifice 47h of the distribution valve 47 coincides. Accordingly, the main cleaning unit 40 can maximize the water pressure by preventing the water pressure sprayed to the first nozzles Na from being dispersed. The main cleaning unit 40 sprays water jets in all directions when the nozzle holes of the first nozzle Na are radially formed in all directions at the upper end. Therefore, the oil inside the baby bottle is evenly and smoothly removed.

Subsequently, when the washing of the baby bottle is completed, the multi-way valve 23 is rotated again to wash the baby products, and the second upper sub nozzle pipe 5b or the lower sub nozzle pipe 5b piped on the opposite side of the washing tub 10 Hot water is supplied to the nozzle pipe 6b. Therefore, the second upper sub-nozzle tube 5b or the lower sub-nozzle tube 6b passes through the second nozzle N in the same manner as the above-described upper sub-nozzle tube 5a or lower sub-nozzle tube 6a. Wash baby products. At this time, the second nozzles (N) spray water jets to the top and bottom of the child care products to wash the child care products.

Here, among the aforementioned second nozzles N, the upper second nozzle N and the lower second nozzle N spray water jets simultaneously or alternately and separately according to the operation of the multi-way valve 23. You can also spray water jets. In addition, the above-described first nozzles Na spray water jets one by one or in pairs alternately by the operation of the distribution valve 47 so that the water pressure of the sprayed water jets is maintained. That is, when the first nozzles Na are injected all at once, the water pressure is weakened, but when only one or a part of the first nozzles Na is injected, it is possible to prevent the water pressure from being weakened as much as possible. Accordingly, the first nozzles Na smoothly clean the inside of the baby bottle.

As shown in FIG. 24, the first nozzle (Na) and the second nozzle (N) are the main nozzle pipe 43 or the sub-nozzle pipes 5a, 5b, 6a, and 6b, and are used for cleaning the washing container CL. Detergent may be introduced and supplied through the detergent control solenoid valve (V). Since the supply of such a detergent is a common technique that can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

Next, basic washing is performed when the preliminary washing is completed in the same manner as described above. This basic washing proceeds in the same way as the above-mentioned preliminary washing, but proceeds in the same way as the preliminary washing with only the number of washings increased.

Then, when the basic washing is completed by the above method, washing water is filled in the washing tub 10 and swirl washing is performed for about 30 seconds to 60 seconds. In the swirl washing, washing water is stored in the washing tank 10 through the first nozzle Na or the second nozzle N described above. As shown in FIGS. 10 and 24 , in the washing tub 10 , the washing water is stored at a water level at which the screw SC provided inside the washing tub 10 is submerged. At this time, it is preferable that the washing water is heated to a medium temperature and stored. When the washing water is stored, the screw (SC) rotates in a forward or reverse direction while at least partially submerged in the washing water, compressing the stored washing water (SC) in the rotational direction to generate a vortex. Therefore, the baby bottles, nipples, and baby products are soaked by the stored washing water, and foreign substances such as oil, which have been called by the impact of the vortex when the vortex is generated, are easily washed.

Subsequently, when the swirl washing is completed, the stored washing water is drained to the drain, and then heating sterilization is performed for about 20 to 40 seconds. Heat sterilization is performed by re-spraying or storing washing water at about 75° C. into the washing tank 10 through the first nozzle (Na) or the second nozzle (N). Heat sterilization is preferably sprayed with a water jet rather than water storage to improve the sterilization effect.

Finally, after the heat sterilization is completed, the blowing fan 91 of the dryer 90 is operated to blow air into the washing tub 10 to dry the baby bottle, nipple, or baby products. At this time, the dryer 90 blows air to the washing tub 10 through the air supply duct 93 and exhausts the air from the washing tub 10 to the exhaust duct 95 . When a heater is provided for rapid drying and sterilization, the dryer 90 blows hot air together through the heater.

Meanwhile, when the first nozzle Na is configured as the elevating nozzle 70 shown in FIGS. 33 to 38, the main cleaning unit 40 spirally lifts and moves the first nozzle Na into a swirling water jet. to inject Accordingly, the inside of the baby bottle is washed with almost no blind spots. In addition, since the elevating nozzle 70 moves up and down according to the size (length) of the baby bottle in the main washing unit 40, the baby bottle is easily installed.

The elevating type nozzle 70 rises by water pressure, but when it descends, it descends by its own weight or the load of the weight 72. In addition, the elevating nozzle 70 forms a vortex in the washing water stored in the washing tub 10 as the vortex blades 75a formed on the outer circumferential surface of the head 75 are rotated during elevation. Thus, the inside of the baby bottle is more smoothly cleaned.

In the embodiment of the present invention as described above, the washing water can be alternately supplied to the main washing part 40 or the sub washing part 20 through the distributor, and the washing water can be saved through this alternating operation, Since the water jet is sprayed, oil can be easily removed.

Also, since the distribution valve 47 can alternately supply the washing water from the main nozzle pipe 43 to the first nozzles Na in an alternating state, it is possible to prevent the water pressure of the water jet ejected from the first nozzle Na from being weakened. In addition, since the distribution valve 47 is composed of a tube for communicating the washing water, it is possible to prevent the water pressure of the washing water from being reduced due to the conventional bottleneck phenomenon.

In addition, when the first nozzle Na is composed of the elevating nozzle 70, the sprayed water jet may be sprayed in a vortex form or generate vortexes in the stored washing water, and in addition, the steel ball B and the guide rail 73a Since the elevating nozzle 70 is rotated and lifted through ), the elevating nozzle 70 can be easily lifted, and furthermore, when the vortex blades 75a are provided in the head 75, the vortex is formed more smoothly can do.

In addition, since the multi-way valve 23 of the distributor rotates inside the valve housing 21 and selectively opens at least one port 21h among the ports 21h of the valve housing 21, washing water is easily supplied. The direction can be changed, and since the multi-way valve 23 is formed in a tubular shape and the washing water is communicated, it is possible to prevent the water pressure of the washing water from being reduced due to a bottleneck phenomenon as in the past.

In addition, by rotating the screw (SC) inside the washing tub 10, waves can be generated inside the washing tub 10, and through this, swirl washing can be performed, so that the nipple or baby bottle that has already been washed with the water jet can be cleaned. It is possible to easily remove foreign substances such as the second.

In addition, washing products can be quickly dried through the dryer 90 or sterilized through hot air, and since the air blown to the air supply duct 93 of the dryer 90 is exhausted through the exhaust duct 95, the air can be smoothly discharged. It is possible to circulate, and it is possible to prevent the washing water of the washing tub 10 from flowing backward to the air supply duct 93 through the backflow prevention baffle 93a provided in the air supply duct 93.

Moreover, since the washing water tanks W1 and W2 are composed of a plurality, the washing water can be smoothly supplied, and thus washing products can be prevented from being contaminated by the washing water already used for washing, and the washing water can be heated to a high temperature through a heater. It can be heated and supplied.
