Description

Technical Field

[0001] This utility model relates to the field of baby bottle cleaning machines, specifically a protective structure for the drying system of a baby bottle cleaning machine. Background Technology

[0002] Current baby bottle washing machine structures are shown in Chinese patent document, application number 202520160380.9, which discloses a drying system protection structure for a baby bottle washing machine. This structure includes a hot air channel and a hot air assembly. The hot air channel comprises a drying channel and a U-shaped air duct with its opening facing downwards. One end of the U-shaped air duct is connected to the hot air assembly, and the other end is connected to the drying channel. The hot air assembly includes a hot air fan and a heater, with the heater located between the outlet end of the hot air fan and the inlet end of the U-shaped air duct. However, in this structure, during the washing process, the high-pressure spray of water causes moisture to be generated in the inner tank. During non-drying operations, this moisture enters the hot air assembly along the hot air channel and comes into contact with the hot air fan and heater, potentially causing leakage, short circuits, or other damage to the hot air fan and / or heater, affecting the service life of the hot air assembly. Therefore, a new drying system is needed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned existing problems and provide a simple and reasonable protective structure for the drying system of a baby bottle washing machine.

[0004] A protective structure for the drying system of a baby bottle washing machine includes a hot air assembly. The hot air assembly includes a housing with a cold air inlet and a hot air outlet. A hot air duct is formed inside the housing between the cold air inlet and the hot air outlet. A centrifugal fan and a heating element are sequentially arranged in the hot air duct. A baffle plate for opening or closing the hot air duct is rotatably connected inside the housing. The baffle plate is located between the heating element and the hot air outlet.

[0005] The objective of this utility model can also be achieved by the following technical measures: As a more specific solution, the steam baffle is provided with a rotating shaft, and the steam baffle is connected to the housing through the rotating shaft. The steam baffle automatically resets by gravity to cut off the hot air duct, and the steam baffle is blown open by the wind force of the centrifugal fan to open the hot air duct.

[0006] As a further embodiment, the hot air assembly also includes a motor mounted on the housing, the output shaft of which is connected to a baffle plate, which is driven to rotate by the motor.

[0007] As a further embodiment, the rotating shaft is located at the top of the steam baffle plate, and the steam baffle plate is vertically positioned inside the hot air duct via the rotating shaft. The steam baffle plate swings left and right around the rotating shaft to open or close the hot air duct.

[0008] As a further embodiment, the hot air duct includes a horizontally arranged hot air generating duct and a vertically arranged hot air guiding duct, with the centrifugal fan and heating element disposed within the hot air generating duct; and the steam baffle is vertically disposed between the hot air generating duct and the hot air guiding duct.

[0009] As a further embodiment, the thickness of the baffle plate gradually increases from the end closer to the rotating shaft to the end farther away from the rotating shaft.

[0010] As a further embodiment, the housing is provided with a cutting-off stop surface between the hot air generating duct and the hot air guiding duct. The cutting-off stop surface is inclined towards the direction of the hot air guiding duct, and the steam baffle plate naturally abuts against the cutting-off stop surface.

[0011] As a further embodiment, the housing is provided with a guide stop surface on the windward side of the hot air generation duct. The guide stop surface is used to define a part of the hot air guiding duct. The guide stop surface is inclined.

[0014] The beneficial effects of this utility model are as follows: This utility model discloses a protective structure for the drying system of a baby bottle washing machine. After the baby bottle is washed, the hot air generated by the hot air assembly blows hot air onto the various parts of the baby bottle to achieve the drying operation. At this time, the steam baffle cuts off the hot air duct during the washing process to prevent water vapor from flowing back into the shell and contacting the centrifugal fan and heating element, thus affecting the service life of the centrifugal fan and heating element. During the drying process, the steam baffle opens the hot air duct, so that when the hot air is blown out, the air pressure of the hot air prevents water vapor from entering, thus providing better protection for the hot air assembly.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] First embodiment: refer to Figures 1 to 4 As shown, a drying system protection structure for a baby bottle washing machine includes a hot air assembly 20. The hot air assembly 20 includes a housing 22, on which a cold air inlet 2002 and a hot air outlet 2001 are provided. A hot air duct is formed inside the housing 22 between the cold air inlet 2002 and the hot air outlet 2001. A centrifugal fan 23 and a heating element 24 are sequentially arranged in the hot air duct. A baffle plate 25 for opening or closing the hot air duct is rotatably connected inside the housing 22. The baffle plate 25 is disposed between the heating element 24 and the hot air outlet 2001.

[0022] In this embodiment, the baffle plate 25 cuts off the hot air duct during the cleaning process to prevent water vapor from flowing back into the housing 22 and contacting the centrifugal fan 23 and the heating element 24, thus affecting the service life of the centrifugal fan 23 and the heating element 24. During the drying process, the baffle plate 25 opens the hot air duct, so that when the hot air is blown out, the air pressure of the hot air stops water vapor from entering, thus providing better protection for the hot air assembly.

[0023] The steam baffle 25 is provided with a rotating shaft 251. The steam baffle 25 is connected to the housing 22 through the rotating shaft 251. The steam baffle 25 automatically resets by gravity to cut off the hot air duct. The steam baffle 25 is blown open by the wind force of the centrifugal fan 23 to open the hot air duct. Specifically: the rotating shaft 251 is located at the top of the steam baffle plate 25, the steam baffle plate 25 is vertically arranged in the hot air duct through the rotating shaft 251, and the steam baffle plate 25 swings left and right around the rotating shaft 251 to realize the opening or closing of the hot air duct.

[0024] When used in conjunction with the above structure: during the non-drying stage, the baffle plate 25 can be reset by its own gravity and maintain a vertical state, thereby cutting off the hot air duct, which can simplify the structure of the hot air assembly 20 and reduce costs. During the drying stage, the centrifugal fan 23 works to generate wind force, which blows the baffle plate 25 open. Under the continuous action of wind force, the hot air duct can remain open.

[0025] The hot air duct includes a horizontally arranged hot air generating duct 221 and a vertically arranged hot air guiding duct 222. The centrifugal fan 23 and the heating element 24 are arranged inside the hot air generating duct 221. The steam baffle 25 is arranged vertically between the hot air generating duct 221 and the hot air guiding duct 222.

[0026] The thickness of the baffle plate 25 gradually increases from the end near the rotating shaft 251 to the end away from the rotating shaft 251. This structure makes the baffle plate 25 set to be lighter at the top and heavier at the bottom. This setting can ensure that the baffle plate 25 can maintain a vertical state under its own gravity during the non-drying stage, ensuring that the hot air duct is cut off.

[0027] The housing 22 is provided with a cutting stop surface 225 between the hot air generating duct 221 and the hot air guiding duct 222. The cutting stop surface 225 is inclined towards the hot air guiding duct 222, and the steam baffle plate 25 naturally abuts against the cutting stop surface 225. If both the cutting stop surface 225 and the steam baffle plate 25 are set vertically, it cannot be guaranteed that the stop surface 225 abuts against the cutting stop surface 225. Therefore, the cutting stop surface 225 is set slightly inclined so that when the steam baffle plate 25 swings down to reset, the cutting stop surface 225 stops the steam baffle plate 25 in advance, ensuring that the two abut against each other. Moreover, the edge position of the steam baffle plate 25 abuts against the cutting stop surface 225 to form a sealing contact surface, so that a gap can be maintained between the steam baffle plate 25 and the front and rear inner walls of the housing 22, preventing the steam baffle plate 25 from getting stuck between the front and rear inner walls when swinging.

[0028] The housing 22 is provided with a guide stop surface 224 on the windward side corresponding to the hot air generating duct 221. The guide stop surface 224 is used to define a part of the hot air guiding duct 222. The guide stop surface 224 is inclined. When the steam baffle 25 is blown open, it leans against the guide stop surface 224. When the steam baffle 25 is blown open, it will lean against the guide stop surface 224, but it can maintain the inclined setting of the steam baffle 25, so that the steam baffle 25 can act as a wind guide plate, which can guide the hot air from the horizontal flow to the downward flow of the hot air guiding duct 222, reducing the wind resistance of the hot air.

[0029] refer to Figure 5As shown, the baby bottle washing machine also includes an inner liner 2 that defines the washing chamber C. The hot air assembly 20 is assembled and connected to one side wall 2a of the inner liner 2, and a hot air outlet 206 communicating with the washing chamber is opened on the same side wall 2a. The hot air outlet 2001 of the hot air assembly 20 is connected to the hot air outlet 206 through the air guide component 21. After the baby bottle is cleaned, the hot air generated by the hot air assembly 20 blows hot air onto the various parts of the bottle to dry them. By arranging the hot air assembly 20 and the hot air outlet 206 on the same side wall 2a of the inner tank 2, the length of the air duct between the two can be shortened, reducing the power loss caused by the long-distance transportation of hot air in the air duct. This allows the hot air blown out of the hot air outlet 206 to maintain a high air pressure, ensuring the drying efficiency of the baby bottle washer.

[0030] The hot air outlet 206 is located below and close to the hot air outlet 2001, and is located in the lower half of the side wall 2a of the inner liner 2. The hot air assembly 20 is higher than the hot air outlet 206, which on the one hand prevents sewage from flowing into the hot air assembly 20, and on the other hand allows hot air to be blown into the cleaning chamber C from the bottom. According to the principle of hot air rising, the hot air can be evenly distributed into the cleaning chamber C, and the hot air can circulate better in the cleaning chamber.

[0031] Second embodiment: The hot air assembly 20 also includes a motor device mounted on the housing 22. The output shaft of the motor device is connected to the steam baffle 25. The steam baffle 25 is driven to rotate by the motor device. The second embodiment differs from the first embodiment in that the steam baffle 25 is driven by an electric motor to achieve full automation. In addition, this embodiment can be understood as adding a motor device on the basis of the first embodiment, so it is not shown in the drawings.

[0032] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
