Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a longitudinal flow directional defoaming valve and a rice cooker. Background Technology

[0002] The rice cooker's efficient and fast cooking method has led to its rapid popularization, making it a common cooking appliance in daily life. It is generally used for cooking rice and porridge. When cooking porridge, the high temperature will cause the rice water to boil and produce bubbles. To address this, rice cookers are generally equipped with a steam box or bubble deflator to separate the air mixed in with the rice water, reducing the possibility of boiling over.

[0003] Most existing bubble breaker components have horizontal bubble-breaking fan blades inside, which break up and divert the gas and bubbles generated when the rice cooker is working.

[0004] However, such structures also have some drawbacks. If the structure is relatively simple, the bubble-breaking effect is not obvious in actual use; if the structure is relatively complex and the exhaust valve can have a significant bubble-breaking effect, it will have problems with inadequate cleaning due to the difficulty in disassembly. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, one of the objectives of this utility model is to invent a longitudinal flow directional defoaming valve with a simple structure and obvious defoaming effect.

[0006] One of the purposes of this utility model is to invent an electric rice cooker.

[0007] One of the objectives of this utility model is achieved through the following technical solution:

[0008] A longitudinal flow directional defoaming valve, comprising:

[0009] The valve body includes a base and a valve cover, the valve cover being mounted on the base and cooperating with the base to form a cavity;

[0010] A bubble-breaking assembly is installed in the cavity. The bubble-breaking assembly includes a bubble-breaking fan and two fixed plates. The two fixed plates are spaced apart on the base. The bubble-breaking fan is disposed between the two fixed plates and is rotatably connected to the two fixed plates.

[0011] An air inlet pipe is disposed within the cavity, with the air outlet of the air inlet pipe facing the direction of the bubble-breaking component, and the air outlet direction of the air inlet pipe being tangential to the rotation direction of the bubble-breaking fan.

[0012] An air vent is provided on the valve cover to allow the cavity to communicate with the outside.

[0013] Furthermore, the air intake pipe is located below the bubble-breaking fan, and the rotation direction of the bubble-breaking fan is tangent to the direction of gravity.

[0014] Furthermore, the air outlet of the air inlet pipe has an arc-shaped surface adapted to the movement path of the bubble-breaking fan.

[0015] Furthermore, it also includes an airflow baffle, which is longitudinally disposed in the cavity and divides the cavity into an installation cavity and a connecting cavity. The bubble breaking component and the air inlet pipe are disposed in the installation cavity, the air outlet is connected to the connecting cavity, and the connecting cavity is connected to the installation cavity.

[0016] Furthermore, the bubble-breaking fan includes a rotating shaft, a hub, and multiple fan blades. The hub is disposed between the two fixed plates and is rotatably connected to the two fixed plates through the rotating shaft. The multiple fan blades are evenly arranged along the axial direction of the hub. The fixed plates are made of plastic material.

[0017] Furthermore, the vertical cross-section of the fan blade is arc-shaped, and the cross-section of the fan blade is a rhombus shape with smaller sides and a larger middle.

[0018] Furthermore, a connecting rod is provided between adjacent fan blades.

[0019] Furthermore, the valve body also includes a sealing ring disposed between the base and the valve cover to seal the gap between the base and the valve cover.

[0020] Furthermore, the sealing ring is sleeved on the outside of the base, a sealing ring is formed on the inner side of the sealing ring, and an annular protrusion adapted to the sealing ring is formed on the outer side of the base.

[0021] The second objective of this utility model is achieved through the following technical solution:

[0022] An electric rice cooker includes a cooker body, a cooker lid, and the aforementioned longitudinal flow directional defoaming valve. The cooker lid is rotatably mounted on the cooker body. The cooker lid has mounting holes. The base is disposed in the mounting holes. Multiple fixing blocks are spaced apart on the outer side of the valve cover. Multiple fixing posts corresponding to the fixing blocks are disposed on the cooker lid. The fixing blocks are connected to the fixing posts by bolts.

[0023] Beneficial effects:

[0024] In this invention, the air outlet direction of the air inlet pipe is tangent to the rotation direction of the bubble-breaking fan, so that the contact surface between the fan blades and the gas-liquid mixture in the bubble-breaking fan changes from the original inclined surface to a flat surface. This increases the contact area between the fan blades and the gas-liquid mixture in the bubble-breaking fan, thereby improving the bubble-breaking effect, reducing liquid overflow, and improving safety during use. Furthermore, the bubble-breaking component consists of two parts: the bubble-breaking fan and the fixing plate, which has a simple structure and is easy to clean. Attached Figure Description

[0039] like Figure 1-6 As shown, a longitudinal flow directional defoaming valve includes...

[0040] Valve body 10, the valve body 10 includes a base 101 and a valve cover 102, the valve cover 102 is mounted on the base 101 and cooperates with the base 101 to form a cavity 103;

[0041] A bubble-breaking component 20 is installed in the cavity 103. The bubble-breaking component 20 includes a bubble-breaking fan 201 and two fixing plates 202. The two fixing plates 202 are spaced apart on the base 101. The bubble-breaking fan 201 is disposed between the two fixing plates 202 and is rotatably connected to the two fixing plates 202.

[0042] An air inlet pipe 30 is disposed in the cavity 103. The air outlet end of the air inlet pipe 30 is disposed in the direction of the bubble breaking component 20, and the air outlet direction of the air inlet pipe 30 is tangent to the rotation direction of the bubble breaking fan 201.

[0043] An air vent 40 is provided on the valve cover 102 to facilitate communication between the cavity 103 and the outside.

[0044] In this embodiment, during operation, the gas-liquid mixture is injected into the cavity 103 through the air inlet pipe 30, and the bubble breaking component 20 breaks the bubbles in the gas-liquid mixture before it is discharged through the air outlet 40.

[0045] Specifically, since the air outlet direction of the air inlet pipe 30 is tangent to the rotation direction of the bubble-breaking fan 201, when the gas pressure inside the rice cooker is low, the gas-liquid mixture is ejected from the air inlet pipe 30 at a low speed, which is insufficient to drive the bubble-breaking fan 201 to rotate. At this time, the fan blades 2013 in the bubble-breaking fan 201 act as a baffle. When the gas-liquid mixture flows through the bubble-breaking component 20, it will directly collide with the fan blades 2013 in the bubble-breaking fan 201, causing the bubbles in the gas-liquid mixture to break. Then, it passes over the fan blades 2013 and is discharged through the air outlet 40.

[0046] When the gas pressure inside the rice cooker is high, the gas-liquid mixture is ejected from the air inlet pipe 30 at a high speed, which can drive the bubble-breaking fan 201 to rotate. After the bubble-breaking fan 201 rotates, each of its blades 2013 will participate in blocking. At this time, the relative function of the blades 2013 is to break the bubbles and intercept most of the starch particles, thereby purifying the steam. Furthermore, through the rotation of the blades 2013, the gas-liquid mixture fully fills the entire cavity 103 and is then discharged to the outside through the air outlet 40 of the exhaust valve cover 102, improving the bubble-breaking efficiency, reducing liquid overflow, and enhancing safety.

[0047] In this invention, the air outlet direction of the air inlet pipe 30 is tangent to the rotation direction of the bubble-breaking fan 201, so that the contact surface between the fan blade 2013 and the gas-liquid mixture in the bubble-breaking fan 201 changes from the original inclined surface to a flat surface, thereby increasing the contact area between the fan blade 2013 and the gas-liquid mixture in the bubble-breaking fan 201, thereby improving the bubble-breaking effect, reducing liquid overflow, and improving safety during use.

[0048] Preferably, in order to further improve the bubble breaking effect, in this embodiment, the air inlet pipe 30 is set below the bubble breaking fan 201, and the rotation direction of the bubble breaking fan 201 is tangent to the direction of gravity. With this setting, the gas-liquid mixture sprayed from the air inlet pipe 30 can be completely sprayed onto the fan blades 2013 of the bubble breaking fan 201, thereby improving the bubble breaking efficiency.

[0049] Furthermore, in order to increase the contact rate between the gas-liquid mixture ejected from the intake pipe 30 and the bubble-breaking fan 201, and to reduce the escape of the gas-liquid mixture from the intake pipe 30 to the bubble-breaking fan 201, in this embodiment, an arc-shaped surface adapted to the movement path of the bubble-breaking fan 201 is formed at the outlet end of the intake pipe 30, so that the intake pipe 30 can fit against the bubble-breaking fan 201, thereby reducing the distance between the intake pipe 30 and the bubble-breaking fan 201, and thus reducing the escape of the gas-liquid mixture.

[0050] Furthermore, to further improve the bubble-breaking effect, this embodiment also includes an airflow baffle. The airflow baffle is longitudinally arranged in the cavity 103 and divides the cavity 103 into an installation cavity 1031 and a connecting cavity 1032. The bubble-breaking component 20 and the air inlet pipe 30 are arranged in the installation cavity 1031. The air outlet 40 is connected to the connecting cavity 1032, and the connecting cavity 1032 is connected to the installation cavity 1031. This arrangement can extend the movement path of the gas-liquid mixture in the valve body 10 and increase the contact area between the gas-liquid mixture and the inner surface of the valve body 10. After the gas-liquid mixture comes into contact with the inner surface of the valve body 10 and the airflow baffle, some of the bubbles in it will directly contact the inner surface of the valve body 10 and the airflow baffle and break, thereby improving the bubble-breaking effect.

[0051] Preferably, in this embodiment, the bubble-breaking fan 201 includes a rotating shaft 2011, a hub 2012, and multiple fan blades 2013. The hub 2012 is disposed between the two fixed plates 202 and is rotatably connected to the two fixed plates 202 through the rotating shaft 2011. The multiple fan blades 2013 are evenly arranged along the axial direction of the hub 2012. The fixed plates 202 are made of plastic material. This arrangement is simple in structure and convenient for users to disassemble and clean. During cleaning, users can separate the bubble-breaking fan 201 from the two fixed plates 202 by partially bending the fixed plates 202 for deep cleaning.

[0052] In addition, to increase the contact area between the fan blade 2013 and the gas-liquid mixture, the vertical cross-section of the fan blade 2013 is set in an arc shape in this example. At the same time, to facilitate the user to clean the fan blade 2013, the cross-section of the fan blade 2013 is set in a rhombus shape with smaller sides and a larger middle, so that the user can directly remove the stains on the surface of the fan blade 2013 by rinsing.

[0053] Meanwhile, in order to improve the overall strength of the bubble-breaking fan 201, in this embodiment, a connecting rod 2014 is provided between adjacent fan blades 2013 to connect multiple fan blades 2013 into one unit, thereby improving the overall strength of the bubble-breaking fan 201.

[0054] In order to prevent the gas-liquid mixture from flowing out from the gap between the base 101 and the valve cover 102, in this embodiment, the valve body 10 also includes a sealing ring, which is disposed between the base 101 and the valve cover 102 to seal the gap between the base 101 and the valve cover 102.

[0055] In order to make the sealing ring and the base 101 fit more tightly, in this embodiment, the sealing ring is sleeved on the outside of the base 101, and a sealing ring is formed on the inside of the sealing ring. An annular protrusion adapted to the sealing ring is formed on the outside of the base 101.

[0056] like Figure 7-8 As shown, an electric rice cooker includes a cooker body, a cooker lid 100, and the aforementioned longitudinal flow directional defoaming valve. The cooker lid 100 is rotatably mounted on the cooker body. The cooker lid 100 is provided with mounting holes. The base 101 is disposed in the mounting holes. A plurality of fixing blocks 1021 are spaced apart on the outer side of the valve cover 102. A plurality of fixing posts 1001 corresponding to the fixing blocks 1021 are provided on the cooker lid 100. The fixing blocks 1021 are connected to the fixing posts 1001 by bolts.

[0057] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
