Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an air duct structure for a baby bottle cleaning machine. Background Technology

[0002] Currently, most baby bottle washing machines are equipped with drying systems or dehydration systems. These systems use fans and PTC heaters, along with appropriate piping, to deliver hot air into the washing chamber, allowing the cleaned bottles to dry faster or remain dry, thus preventing bacterial growth.

[0003] Its structure is similar to that of Chinese invention CN109674428B, "A Drying System for a Baby Bottle Washing Machine and a Baby Bottle Washing Machine," which includes: a fan for supplying air to the washing chamber of the baby bottle washing machine and the baby bottles positioned within the washing chamber; a lower air duct, in which the fan is disposed, with the air inlet of the lower air duct communicating with the air inlet of the fan, and the air outlet of the lower air duct communicating with the air outlet of the fan; a side air duct, having a vertical extension section, with the air inlet of the side air duct communicating with the air outlet of the lower air duct, and also communicating with the air outlet of the side air duct through the vertical extension section; an inner air duct, installed within the washing chamber, with the air inlet of the inner air duct communicating with the air outlet of the side air duct, and the air outlet of the inner air duct extending into the bottle opening; and an air heater, through which the temperature of the air discharged by the fan is increased.

[0004] To prevent hot and humid air or water from flowing back to the fan during the rinsing of baby bottles, it is proposed that a check valve be installed in the side air duct, especially the simple design of the air damper set at the high position of the inverted U-shaped structure, effectively prevent hot and humid air inside the washing chamber from flowing to the outside of the washing chamber.

[0005] However, when rinsing the baby bottles, the wastewater in the washing chamber will enter the air duct. The wastewater often carries milk stains and other dirt that cause the air duct to become dirty. The aforementioned check valve can only block the wastewater at the high position of the inverted U-shaped structure, and cannot keep the air duct clean. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-8 A duct structure for a baby bottle washing machine includes a housing 1 with a washing chamber 101, and a drying system is provided on the housing 1. The drying system is used to deliver hot air into the washing chamber 101 so that the cleaned items (such as baby bottles) can be quickly dried or kept dry.

[0022] In some embodiments, the drying system includes an air duct, a fan 2, and an air heater 3. The air duct is connected to the cleaning chamber 101, the fan 2 supplies air into the cleaning chamber 101 through the air duct, and the air heater 3 heats the air supplied into the cleaning chamber 101 to form hot air.

[0023] In some embodiments, the air heater 3 includes a PTC heater disposed in the air duct.

[0024] In some embodiments, the drying system can also be used to deliver high-temperature hot air for high-temperature sterilization.

[0025] In some embodiments, the air duct includes a first air duct 4 arranged vertically, the lower end of the first air duct 4 is connected to the cleaning chamber 101, and the air delivered by the fan 2 flows from top to bottom through the first air duct 4 and is finally sent into the cleaning chamber 101.

[0026] In some embodiments, the air duct further includes a second air duct 6 that connects the air duct 5 and the upper and lower air ducts 6, and the upper air outlet of the second air duct 6 is connected to the upper air outlet of the first air duct 4 through the air duct 5.

[0027] The air delivered by the fan 2 flows upward through the second air duct 6, then through the connecting air duct 5 to reach the first air duct 4, and then flows downward through the first air duct 4 before finally being sent into the cleaning chamber 101.

[0028] In some embodiments, the connecting duct 5 is arranged in an inverted U-shape.

[0029] In some embodiments, the air duct further includes a drainage air duct 7, one end of which is connected to the lower end of the second air duct 6.

[0030] The drainage duct 7 and the second duct 6 are bent at a certain angle to form a bend 701 at the connection between the drainage duct 7 and the second duct 6.

[0031] For example, the drainage duct 7 is set horizontally, and the drainage duct 7 and the second duct 6 are set at a 90° bend.

[0032] The air outlet of the fan 2 is connected to the air outlet at the other end of the drainage duct 7, and the air heater 3 is installed inside the drainage duct 7 and away from the bend 701.

[0033] A water stop 702 is provided at the bottom of the bend 701. When water flows downward in the second air duct 6 after passing through the first air duct 4 and the connecting air duct 5, the bend 701 and the water stop 702 allow the downward-flowing water to be discharged at the bend 701, reducing the impact of the water on the air heater 3 and the fan 2. In some embodiments, a water-blocking protrusion 703 is provided in the drainage duct 7 near the bend 701. The water-blocking protrusion 703 forms a certain degree of water level resistance, so that the water flowing down to the bend 701 is less likely to continue flowing to the fan 2 and the air heater 3 due to the resistance of the water-blocking protrusion 703.

[0034] In some embodiments, the drying system further includes a plasma generator 8, the plasma generated by the plasma generator 8 being sent into the cleaning chamber 101 along with the air.

[0035] In some embodiments, the plasma generator 8 is disposed within the drainage duct 7.

[0036] In some embodiments, the drying system further includes an overflow prevention component that allows gas to be delivered into the cleaning chamber through the air duct and restricts water in the cleaning chamber from overflowing through the air duct.

[0037] In some embodiments, the side of the cleaning chamber 101 has a connecting vent 102 corresponding to the lower end vent of the first air duct 4.

[0038] The overflow prevention component includes a first baffle plate 9 installed at the lower end of the ventilation opening or the first air duct.

[0039] The upper part of the first baffle plate is rotatably connected to the upper edge of the connecting vent; or the lower end of the first air duct is horizontally inserted into the connecting vent, and the upper part of the first baffle plate is rotatably connected to the upper edge of the lower end air vent of the first air duct.

[0040] The first water baffle 9 can be flipped downwards under the action of gravity to cover the lower air vent of the connecting vent or the first air duct.

[0041] After the first baffle plate 9 covers the lower air vent of the connecting vent or the first air duct, when the first baffle plate 9 is subjected to external pressure (such as water pressure), the first baffle plate 9 rotates in the direction that it is more securely covered on the connecting vent or the lower air vent.

[0042] After the first baffle plate 9 covers the connecting vent or the lower air outlet, when the fan 2 delivers air, the wind force correspondingly pushes the first baffle plate 9 to rotate, so that there is an air outlet gap between the first baffle plate 9 and the connecting vent or the lower air outlet of the first air duct, so as to deliver air smoothly.

[0043] In this embodiment, the first baffle plate 9 is designed to block water at the end of the air duct (i.e., the connection with the cleaning chamber), thereby preventing water from entering the air duct as much as possible. This includes blocking splashing water generated during rinsing and blocking water with water pressure when the water level is high.

[0044] like Figure 7 , 8 As shown, in some embodiments, when the first baffle plate 9 is configured to be located at the connecting vent, and the upper part of the first baffle plate 9 is rotatably connected to the upper edge of the connecting vent: the upper edge of the connecting vent can be formed with a pivot seat 103.

[0045] The first baffle plate 9 is provided with a rotating shaft that cooperates with the rotating shaft seat 103, so that the first baffle plate 9 can be flipped down to cover the lower air vent of the connecting vent or the first air duct.

[0046] In some embodiments, when the lower end of the first air duct is laterally inserted into the ventilation opening, and the upper part of the first baffle plate is rotatably connected to the upper edge of the lower end air opening of the first air duct: the lower end of the first air duct may be formed with a pivot seat, and the first baffle plate is provided with a pivot that cooperates with the pivot seat, so that the first baffle plate can be flipped down to cover the lower end air opening of the first air duct.

[0047] In some embodiments, the overflow prevention assembly further includes a second baffle plate 10 disposed within the second air duct 6.

[0048] The inner wall of the second air duct 6 is formed with a circumferential water-blocking protrusion 11 that extends horizontally along the circumference of the second air duct. The circumferential water-blocking protrusion 11 has a connecting channel 12 in the middle that corresponds to the channel of the second air duct 6. A hinge seat 13 is provided at the top of the circumferential water-blocking protrusion 11. One side of the second water baffle 10 is rotatably connected to the hinge seat 13. The second water baffle 10 can be flipped downwards under the action of gravity to cover the circumferential water baffle 11, thus blocking the second air duct 6.

[0049] After the second baffle plate 10 covers the circumferential water-blocking protrusion, when the fan 2 delivers air, the wind force correspondingly pushes the second baffle plate 10 to rotate, so that the connecting channel 12 between the second baffle plate 10 and the circumferential water-blocking protrusion has an air outlet gap, so as to deliver air smoothly.

[0050] After the second baffle plate 10 covers the circumferential water-blocking protrusion 11, the second baffle plate 10 will remain covered by the circumferential water-blocking protrusion 11 in the absence of any external force other than gravity. When the steam or water in the cleaning chamber 101 flows to the second air duct 6, the second baffle plate 10 can maintain a good covering state to block the steam or water.

[0051] In this embodiment, the first baffle plate 9 and the second baffle plate 10 are combined to form a lateral baffle and a vertical baffle, which makes the water blocking effect better; and when the casing is tilted to the side, the combination of the above-mentioned lateral baffle and vertical baffle can better deal with the water blocking and steam blocking when tilted to the side.

[0052] In some embodiments, the second air duct 6 may be formed by connecting at least two halves of the housing, and the drainage air duct 7 may be formed by connecting at least two halves of the housing, so as to facilitate the installation of structural components located inside them.

[0053] In some embodiments, a temperature sensor is also provided in the air duct to detect the temperature of the air heater or to detect the air temperature.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
