Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a steam valve cover assembly, a cover structure of a cooking device, and the cooking device. Background Art

[0002] The prior art discloses an electric rice cooker having a cover structure provided with a steam inlet, a steam flow passage, a steam outlet, and a steam valve cover covering the steam outlet. The cover structure is further provided with a motor, a gear, a rotating seat, and a push rod connected to the rotating seat. The other end of the push rod is connected to the steam valve cover. The motor drives the gear to rotate, which in turn drives the rotating seat to rise and fall. The rotating seat pushes the push rod to rise and fall, thereby driving the steam valve cover to rise and fall, thereby achieving variable steam outlet area. When the steam outlet area reaches a maximum, even if high-power heating is continuously performed, rice soup will not overflow from the steam valve, thereby enabling the electric rice cooker to achieve continuous high-power heating, greatly improving the cooking speed of the electric rice cooker and enhancing the user experience. However, the steam valve cover of the electric rice cooker is integrally provided with the push rod and cannot be removed for cleaning. Long-term use will cause dust to accumulate on the steam valve cover, which may breed bacteria during cooking, affecting the health of the user. Summary of the Invention

[0028] A third aspect of the present invention provides a cooking device comprising the cover structure as described above.

[0029] The cooking device is an electric rice cooker.

[0030] The technical solution of the present invention has the following advantages:

[0031] 1. The steam valve cover assembly provided by the present invention is provided with a driving device and a transmission mechanism, so that under the drive of an external force, the transmission mechanism has a second state in which it remains connected to the push rod of the cover structure, which can ensure the connection between the steam valve cover assembly and the push rod, so that the valve cover structure is fixedly connected to the push rod, and the push rod can drive the steam valve cover assembly to perform lifting movements to ensure the normal operation of the steam valve. At the same time, when an external force acts on the driving device, the driving device can drive the transmission mechanism to move, so that the transmission mechanism has a first state in which it is disconnected from the push rod, so that the steam valve cover assembly can be disconnected from the cover structure. The steam valve cover assembly can be removed from the cover structure and cleaned when needed, thereby ensuring the cleanliness of the steam valve cover assembly, ensuring the normal use of the cooking equipment, and then ensuring the health of the user, thereby improving the user's comfort and experience.

[0032] 2. The steam valve cover assembly provided by the present invention provides a transmission rod on the valve cover structure, so that when the driving device drives the transmission rod to move, the transmission rod can have a support, and the movement can be more stable.

[0033] 3. The steam valve cover assembly provided by the present invention forms a lever structure by arranging a support portion on the valve cover structure, and the support portion clamps both sides of the transmission rod. The support portion is the fulcrum for the movement of the transmission rod. When the driving device drives one end of the transmission rod, the other end of the transmission rod can be driven in the opposite direction. For example, when the driving device presses one end of the transmission rod downward, the other end of the transmission rod will tilt upward. Since the other end of the transmission rod is engaged with the push rod, the transmission rod can be easily disconnected from the push rod. The structural setting is relatively simple and the operation is relatively convenient.

[0034] 4. The steam valve cover assembly provided by the present invention has at least three supporting parts, which are spaced apart around the driving device, so that the connection between the transmission mechanism and the push rod is more secure and the driving device is more stable when driving.

[0035] 5. The steam valve cover assembly provided by the present invention makes the connection between the transmission mechanism and the push rod simpler and more convenient to assemble and disassemble by clamping the other end of the transmission mechanism with the push rod.

[0036] 6. The steam valve cover assembly provided by the present invention has a simpler structure by configuring the driving device to include a driving member and a biasing member. When the external force acts on the driving member during operation, the force can be transmitted to one end of the transmission rod and the biasing member. When the other end of the transmission rod is disconnected from the biasing member, the external force is removed and the biasing member can realize the resetting of the transmission rod, thereby preparing for the next engagement of the transmission rod and the push rod.

[0037] 7. The steam valve cover assembly provided by the present invention facilitates the arrangement of the transmission mechanism and the biasing member by configuring the valve cover structure as an upper cover and a lower cover that are detachably connected.

[0038] 8. The cover structure of the cooking device provided by the present invention is configured by arranging a first step surface on the push rod. The first step surface is arranged outside the accommodating hole and is offset against the accommodating hole, so that when the driving assembly drives the push rod to move, the push rod can directly drive the steam valve cover assembly to move up and down, and prevent the push rod from excessively moving into the valve cover structure.

DETAILED DESCRIPTION

[0051] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0052] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] like Figure 1 - Figure 8 As shown, this embodiment provides a steam valve cover assembly suitable for being arranged on a cover structure of a cooking device. The cover structure is provided with a push rod 1 connected to the steam valve cover assembly to drive the steam valve cover assembly to move up and down, including:

[0056] Valve cover structure;

[0057] A driving device is provided on the valve cover structure;

[0058] The transmission mechanism has one end connected to the driving device and the other end suitable for being connected to the push rod 1. When an external force acts on the driving device, the driving device drives the transmission mechanism to move, so that the transmission mechanism has a first state in which it is disconnected from the push rod 1, and has a second state in which the transmission mechanism remains connected to the push rod 1 under the drive of the external force.

[0059] By setting up a driving device and a transmission mechanism, the transmission mechanism has a second state in which it remains connected to the push rod 1 of the cover structure under external force, which can ensure the connection between the steam valve cover assembly and the push rod 1, so that the valve cover structure is fixedly connected to the push rod 1, and the push rod 1 can drive the steam valve cover assembly to move up and down, ensuring the normal operation of the steam valve. At the same time, when external force acts on the driving device, the driving device can drive the transmission mechanism to move, so that the transmission mechanism has a first state in which it is disconnected from the push rod 1, so that the steam valve cover assembly can be disconnected from the cover structure, and the steam valve cover assembly can be removed from the cover structure and cleaned when needed, thereby ensuring the cleanliness of the steam valve cover assembly, ensuring the normal use of the cooking equipment, and then ensuring the health of the user, thereby improving the user's comfort and experience.

[0060] The transmission mechanism in this embodiment includes a transmission rod 2, which is provided on the valve cover structure. One end of the transmission rod 2 is connected to the driving device, and the other end of the transmission rod 2 is suitable for connecting to the push rod 1. By providing the transmission rod 2 on the valve cover structure, the driving device can support the transmission rod 2 when driving the transmission rod 2, and the movement can be more stable.

[0061] like Figure 2 and Figure 3 As shown, the valve cover structure of this embodiment is provided with three support portions 17. The support portions 17 are provided on both sides of the transmission rod 2 and are suitable for clamping the transmission rod 2 so that the transmission rod 2 forms a lever structure with the support portions 17 as the fulcrum. By providing the support portions 17 on the valve cover structure and clamping the support portions 17 on both sides of the transmission rod 2, the transmission mechanism forms a lever structure. The support portions 17 are the fulcrums for the movement of the transmission rod 2. When the driving device drives one end of the transmission rod 2, it can perform the opposite action on the other end of the transmission rod 2. For example, when the driving device presses one end of the transmission rod 2 downward, the other end of the transmission rod 2 will tilt upward. Since the other end of the transmission rod 2 is engaged with the push rod 1, the transmission rod 2 can be easily disconnected from the push rod 1. The structure is relatively simple and the operation is relatively convenient. As a convertible embodiment, it is also possible that the driving device drives one end of the transmission rod 2 to move, and horizontally drives the other end of the transmission rod 2 to connect to the push rod 1 or move away from the push rod 1 to achieve connection or disconnection with the push rod 1.

[0062] Three support portions 17 are evenly spaced around the drive mechanism, each supporting portion 17 sandwiching a transmission rod 2. The other end of each transmission rod 2 is connected to a push rod 1. Providing three support portions 17, evenly spaced around the drive mechanism, strengthens the connection between the transmission mechanism and the push rod 1, and provides greater stability during operation of the drive mechanism. Alternatively, four or more support portions 17 may be provided, or their arrangement may be tailored to the specific space available in the valve cover structure.

[0063] Specifically, each support portion 17 in this embodiment includes: opposing support units 3, each of which is provided with a semicircular receiving groove; opposing support columns 4, each of which is disposed within the receiving groove, and the opposing support columns 4 sandwiching the two sides of the transmission rod 2. The support units 3 and support columns 4 sandwich the two sides of the transmission rod 2, providing a more secure support for the transmission rod 2, while also simplifying the structure and facilitating assembly.

[0064] like Figure 5 As shown, the other end of the transmission rod 2 in this embodiment is suitable for being engaged with the push rod 1. Specifically, the other end of the transmission rod 2 is a buckle structure 5, as shown in FIG. Figure 9As shown, push rod 1 is provided with a groove 6 that engages with a snap structure 5. The snap structure 5 comprises a handle extending downward from the other end of the transmission rod 2 and a hook extending from the end of the handle away from the transmission rod 2 toward the groove 6. By snapping the other end of the transmission rod 2 to push rod 1, the connection between the two is simplified and assembly and disassembly are more convenient. Alternatively, the other end of the transmission rod 2 may be grooved, and push rod 1 may be provided with a snap structure that engages with the groove.

[0065] like Figure 1 As shown, the drive device in this embodiment includes: a driver, disposed at one end of the valve cover structure; a biasing member, disposed at the other end of the valve cover structure opposite the driver, with one end of the transmission mechanism disposed between the biasing member and the driver. The biasing member is adapted to provide a reset force for the transmission mechanism after the external force acting on the driver ceases. Specifically, in this embodiment, the driver is a button 8, and the biasing member is a spring 9. By configuring the drive device to include the driver and the biasing member, the drive device structure is simplified. During operation, external force acting on the driver transmits the force to one end of the transmission rod 2 and the biasing member. When the other end of the transmission rod 2 is disconnected from the biasing member, the external force is removed, and the biasing member resets the transmission rod 2, preparing for the next engagement of the transmission rod 2 with the push rod 1. As an alternative embodiment, the drive device may be a resilient button. When the user presses the button once, the resilient button moves downward, and when the user presses the button a second time, the resilient button moves upward to reset.

[0066] Three mounting feet 7 are provided on one side of the button 8 near the spring 9. Each mounting foot 7 corresponds to each transmission rod 2. The mounting foot 7 abuts one end of the transmission rod 2. A protrusion is provided on one end of the transmission rod 2, and the protrusion is inserted into the spring 9. As an alternative embodiment, the specific number of mounting feet 7 can also be set according to the specific number of transmission rods 2.

[0067] The valve cover structure in this embodiment includes an upper cover 10 and a lower cover 11 connected by snaps. A space for accommodating the transmission rod 2 and the biasing member is formed between the upper and lower covers 10, 11. By configuring the valve cover structure as a detachably connected upper and lower covers 10, 11, the installation of the transmission rod 2 and the biasing member is facilitated. Alternatively, the upper and lower covers 10, 11 may be connected by screws or other detachable connection methods known in the art. This will not be discussed in detail here.

[0068] Specifically, a through hole 20 is provided at the upper end of the upper cover 10, and a button 8 is provided in the through hole 20. A spring 9 is provided on the lower cover 11. The spring 9 is arranged corresponding to the mounting feet 7 on the button 8. The three mounting feet 7 are evenly spaced around the through hole 20. The mounting feet 7 on the button 8 abut against one end of the transmission rod 2, and the protrusion below one end of the transmission rod 2 is inserted into the spring 9. As a convertible embodiment, it is also possible that on one side of the upper cover 10, when the push rod 1 is arranged on the right side of the upper cover 10, a through hole 20 can be provided on the left side of the upper cover 10, a spring 9 is provided on the right side of the upper cover 10, and a button 8 is provided in the through hole 20. The button 8 is connected to one end of the transmission rod 2 and the free end of the spring 9, and the other end of the transmission rod 2 is provided with a snap structure 5. When the button 8 is not pressed, the snap structure 5 of the transmission rod 2 remains connected to the groove 6 on the push rod 1. When the user presses the button 8, the transmission rod 2 moves to the right, and the snap structure 5 is separated from the groove 6, thereby realizing the disconnection of the steam valve cover assembly from the push rod 1. When the user moves his hand away from the button 8, the spring 9 resets the button 8 and the transmission rod 2.

[0069] When the steam valve is working normally, the buckle structure 5 on the other end of the transmission rod 2 on the steam valve cover assembly is buckled and connected with the groove 6 on the push rod 1, so that the push rod 1 and the steam valve cover assembly form a whole. When the push rod 1 moves up and down, it can drive the steam valve cover assembly to move up and down, so that the area of the steam outlet 14 can be changed. When the steam valve cover assembly needs to be cleaned, the button 8 on the upper cover 10 can be pressed down. The button 8 will drive one end of the transmission rod 2 to move downward, and then the other end of the transmission rod 2 will move upward, so that the buckle structure 5 of the transmission rod 2 and the groove 6 on the push rod 1 are buckled and connected. After the cleaning is completed, the user presses the button 8 and the spring 9 on the bottom of the steam valve cover to release the spring 9 from the pressure on the steam outlet 14, and the buckle structure 5 on the other end of the transmission rod 2 will automatically engage with the groove 6 on the push rod 1, thereby realizing the second state in which the steam valve cover assembly and the push rod 1 remain connected, thereby ensuring the normal operation of the steam valve.

[0070] like Figure 5-Figure 9 As shown, this embodiment also provides a cover structure of a cooking device, including:

[0071] Inner cover body 12;

[0072] A steam valve is provided on the inner cover body 12 and has a steam inlet 13, a steam outlet 14, and a steam passage provided between the steam inlet 13 and the steam outlet 14. The steam inlet 13 is connected to the pot body of the cooking device, and the steam valve cover assembly 19 is provided at the steam outlet 14.

[0073] The driving assembly is arranged on the inner cover body 12 and includes a push rod 1. The push rod 1 is detachably connected to the other end of the transmission mechanism. The driving assembly drives the push rod 1 to drive the steam valve cover assembly 19 to move up and down.

[0074] Among them, the driving component, such as the background technology part, includes a motor, a gear, a rotating seat, and a push rod 1 connected to the rotating seat. The other end of the push rod 1 is connected to the steam valve cover assembly 19. The motor drives the gear to rotate, and the gear drives the rotating seat to rotate while driving the rotating seat to rise and fall. The rotating seat pushes the push rod 1 to rise and fall, and then drives the steam valve cover assembly 19 to rise and fall, so as to realize the variable size of the steam outlet 14 area.

[0075] like Figure 9 As shown, the push rod 1 in this embodiment is a metal guide column, and a first step surface 15 is provided on the push rod 1. Figure 1 As shown, the lower cover 11 of the valve cover structure is provided with a receiving hole 18, and the first step surface 15 is provided outside the receiving hole 18 and abuts against the lower end of the receiving hole 18. By providing the first step surface 15 on the push rod 1, the first step surface 15 is provided outside the receiving hole 18 and abuts against the receiving hole 18, so that when the drive assembly drives the push rod 1 to move, the push rod 1 can directly drive the steam valve cover assembly 19 to move up and down, and prevent the push rod 1 from excessive movement into the valve cover structure.

[0076] A second step surface 16 is provided on the push rod 1. The second step surface 16 is provided above the first step surface 15 and is located in the accommodating space of the valve cover structure. The length of the second step surface 16 in the horizontal direction is smaller than that of the first step surface 15. A groove 6 is formed on the second step surface 16 to cooperate with the snap structure 5 of the transmission rod 2.

[0077] This embodiment also provides a cooking device, including the cover structure as described above.

[0078] Specifically, the cooking device is an electric rice cooker. As a convertible embodiment, it can also be that the cooking device is an electric pressure cooker.

[0079] The electric rice cooker is used for cooking rice by rotating the gear driven by the motor. The gear drives the rotating seat to rotate while driving the rotating seat to rise and fall. The rotating seat pushes the push rod 1 to rise and fall. Since the transmission rod 2 of the steam valve cover assembly 19 is connected to the push rod 1 by a buckle, the steam valve cover assembly 19 can be driven to rise and fall, so as to realize the variable size of the steam outlet 14 areas and ensure the speed of cooking. When the service life is long and the steam valve cover assembly 19 needs to be cleaned, the user can press the button 8 on the upper cover 10 so that the buckle structure 5 of the transmission rod 2 of the steam valve cover assembly 19 is disengaged from the groove 6 of the push rod 1, so as to realize the separation of the steam valve cover assembly 19 and the inner cover body 12 of the electric rice cooker. The user can remove the steam valve cover assembly 19 for cleaning. After cleaning is completed, the steam valve cover assembly 19 can be assembled downwards to the steam outlet 14 by force, so that the buckle structure 5 of the transmission rod 2 is buckled in the groove 6 of the push rod 1, so as to realize that the steam valve cover assembly 19 remains connected with the push rod 1 to ensure the normal cooking function of the subsequent electric rice cooker. Since the steam valve cover assembly 19 in this embodiment can be connected to and disconnected from the inner cover body 12 of the rice cooker, it can be cleaned in time when needed, ensuring the cleanliness of the steam valve cover assembly 19, thereby ensuring the cleanliness of the rice cooker and the health of the user.

[0080] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
