Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and more specifically, to a cooking utensil feeding device and a cooking utensil. Background Technology

[0002] Currently, some cooking machines use a multi-burner system, which typically includes multiple burners and feeders, usually in a 1:1 ratio, or uses a feeding arm to feed different burners. The 1:1 burner-to-feeder ratio requires multiple feeders, which are expensive, thus significantly increasing the overall cost of the multi-burner system. As for the feeding arm system, its exposed moving parts negatively impact reliability and safety. Utility Model Content

[0003] The main purpose of this utility model is to provide a cooking utensil feeding device and a cooking utensil to solve the problem of high cost of multi-burner cooking machines in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a cooking utensil feeding device is provided, comprising: a housing having an outer feeding port and an outer feeding port, wherein there are at least two outer feeding ports; a switching member movably disposed within the housing, the switching member having a feeding channel having an inner feeding port and an inner feeding port, the inner feeding port being connected to the outer feeding port, the inner feeding port being connected to the outer feeding port, and the inner feeding port being able to be connected to the outer feeding port by moving the switching member; and a driving member drivingly connected to the switching member and driving the switching member to move within the housing to change the outer feeding port that is connected to the inner feeding port.

[0005] Furthermore, the switching element is rotatably disposed within the housing, and the axis of each discharge port is eccentrically disposed relative to the rotation axis of the switching element.

[0006] Furthermore, the axes of each external and internal discharge port are set parallel to the rotation axis of the switching component, and each external discharge port is arranged circumferentially along the rotation axis of the switching component.

[0007] Furthermore, the axes of the outer feed inlet and the inner feed inlet are set to coincide with the rotation axis of the switching component.

[0008] Furthermore, the outer feed inlet and the outer discharge outlet are located on opposite sides of the outer casing, while the inner feed inlet and the inner discharge outlet are located on opposite sides of the switching component.

[0009] Furthermore, a gap is provided between the inner wall of the outer casing and the outer wall of the switching component, forming a balance channel between the two. The outgoing material outlet has a connected state with the inner outgoing material outlet, and the outgoing material outlet in the non-connected state is connected to the balance channel. The outer casing has an air inlet, which is connected to the balance channel. The air inlet inputs gas to the outgoing material outlet through the balance channel, so that the outgoing material outlet maintains positive pressure.

[0010] Furthermore, the air intake is located on the end face or circumferential sidewall of the casing.

[0011] Furthermore, the side surface of the switching component facing the outlet has a protrusion and a first recess, the inner outlet is located on the surface of the protrusion, and the first recess forms at least a partial balance channel between the inner wall surface of the outer casing.

[0012] Furthermore, the air inlet and the discharge outlet are located on opposite sides of the outer casing, and an annular gap is formed between the circumferential side of the switching component and the outer casing. The side surface of the switching component facing the air inlet has an annular second recess, and the air inlet is located at the second recess. The first recess, the annular gap, and the second recess are connected and together form a balance channel.

[0013] Furthermore, the cooking appliance feeding device also includes a sealing element, which is disposed between the switching element and the outer shell and seals the circumferential gaps at the junction of the outer feeding port and the inner feeding port, and at the junction of the outer feeding port and the inner discharging port.

[0014] Furthermore, the side surface of the switching component facing the outer feed port has a sealing protrusion, and the sealing component at the inner feed port is fitted onto the sealing protrusion and protrudes from the end face of the sealing protrusion. When the switching component is connected to the housing, the switching component squeezes the sealing component, causing the sealing component to deform to seal the gap between the switching component and the housing.

[0015] Furthermore, multiple seals are provided between the external discharge port and the internal discharge port, including fixed seals and movable seals. The fixed seals are connected to the inner end face of the outer shell, and the movable seals are set on the end face of the switching member and move synchronously with the switching member. When the switching member docks with the outer shell, the seal at the internal inlet squeezes the switching member, so that the movable seals and the fixed seals are sealed together.

[0016] Furthermore, the fixed seal and / or movable seal are ceramic parts or ceramic composite parts.

[0017] Furthermore, the cooking appliance feeding device also includes a positioning component, which is disposed between the outer shell and the switching component. When the switching component moves to a predetermined position, the outer shell and the switching component are positioned and engaged by the positioning component.

[0018] Furthermore, the positioning component includes a sensed element and a sensor. The sensed element is disposed on the switching element and moves synchronously with the switching element. The sensor is disposed on the housing and can sense the position of the sensed element to determine the position of the switching element.

[0019] Furthermore, the positioning component includes: a ball, which is movably disposed within the housing and is capable of extending into or out of the switching member; an elastic member, which abuts against the ball and provides elastic force for the ball to extend into the switching member; when the switching member moves under the drive of the drive member, it pushes the ball out of the switching member; when the switching member moves to a predetermined position, the ball extends into the switching member.

[0020] According to another aspect of the present invention, a cooking utensil is provided, including the above-described cooking utensil feeding device.

[0021] By employing the technical solution of this utility model, a switching component with a material conveying channel is installed inside the outer casing. A driving component can move the switching component within the casing, allowing the inner discharge port on the switching component to selectively switch between outer discharge ports. This changes the outer discharge port that mates with the inner discharge port. Material enters the conveying channel from the outer inlet through the inner inlet and exits from the inner discharge port through the corresponding specific outer discharge port, achieving discharge at a specific location. When the discharge location needs to be changed, the driving component simply actuates the switching component, causing the inner discharge port to change its corresponding outer discharge port, allowing material to be discharged from that port. This configuration allows the feeding device to feed different furnace heads, achieving a one-to-many structure. This reduces the required number of components, thus lowering costs. Furthermore, since most components, including the switching component, are housed within the outer casing, exposed moving parts are avoided, effectively ensuring reliability and safety, and achieving stable operation while balancing cost.

[0034] To address the high cost of existing multi-burner cooking machines, this invention provides a cooking utensil feeding device and a cooking utensil. The cooking utensil includes the following feeding device.

[0035] like Figures 1 to 6The cooking appliance feeding device shown includes a housing 10, a switching element 20, and a driving element 30. The housing 10 has an outer feeding port 11 and an outer feeding port 12, with at least two outer feeding ports 12. The switching element 20 is movably disposed within the housing 10 and has a feeding channel 21. The feeding channel 21 has an inner feeding port 22 and an inner feeding port 23. The inner feeding port 22 is connected to the outer feeding port 11, and the inner feeding port 23 is connected to the outer feeding port 12. The inner feeding port 23 can be changed to connect with the outer feeding port 12 by moving the switching element 20. The driving element 30 is drivenly connected to the switching element 20 and drives the switching element 20 to move within the housing 10 to change the outer feeding port 12 that is connected to the inner feeding port 23.

[0036] In this embodiment, a switching element 20 is provided inside the outer casing 10. The switching element 20 is provided with a material conveying channel 21. The driving element 30 can drive the switching element 20 to move inside the outer casing 10, so that the inner discharge port 23 on the switching element 20 can selectively switch between the outer discharge port 12, thereby changing the outer discharge port 12 that is connected to the inner discharge port 23. In this way, after the material enters the material conveying channel 21 from the outer feed port 11 through the inner feed port 22, it is output from the inner discharge port 23 through the corresponding specific outer discharge port 12, thereby achieving the effect of discharging material at a specific position. When it is necessary to change the discharge position, the driving element 30 only needs to drive the switching element 20 to move, so that the inner discharge port 23 changes the corresponding outer discharge port 12, and the material can be discharged from the outer discharge port 12. The above configuration allows the feeding device to feed materials to different furnace heads, thus achieving a one-to-many structure. This reduces the required number of components, which helps to lower costs. Furthermore, most components, such as the switching component 20, are housed within the outer casing 10, preventing exposed moving parts and effectively ensuring reliability and safety. This approach balances cost considerations with stable operation.

[0037] This embodiment uses a stir-fry machine as an example of a cooking appliance. Of course, the food feeding device can also be applied to other types of cooking appliances, as long as it can meet the needs of feeding different materials.

[0038] like Figure 4 and Figure 5As shown, the switching component 20 in this embodiment is in the form of a rotating body, rotatably disposed within the outer casing 10. Since the inner outlet 23 needs to switch positions to mate with different outer outlets 12 when the switching component 20 rotates, this embodiment uses an eccentric arrangement of the axes of each outer outlet 12 and the inner outlet 23 relative to the rotation axis of the switching component 20. Thus, when the switching component 20 rotates, the inner outlet 23 can rotate around the central axis of the switching component 20, thereby switching positions between the eccentrically arranged outer outlets 12 and achieving the effect of mating with different outer outlets 12. Of course, in addition to the rotatable arrangement, other arrangements such as a movable arrangement can also be used.

[0039] In this embodiment, the axes of each outgoing discharge port 12 and the inner discharge port 23 are arranged parallel to the rotation axis of the switching member 20, and the distance between them and the rotation axis of the switching member 20 is approximately equal. This ensures that the inner discharge port 23 can accurately engage with each outgoing discharge port 12 when its position changes, guaranteeing smooth material transport. Preferably, each outgoing discharge port 12 is arranged at equal intervals along the circumference of the rotation axis of the switching member 20. In this way, the outgoing discharge ports 12 are approximately symmetrically arranged relative to the circumference of the switching member 20, allowing the switching member 20 to achieve engagement between the inner discharge port 23 and another outgoing discharge port 12 with each fixed rotation angle, facilitating control.

[0040] Unlike the eccentric arrangement of the external discharge port 12 and internal discharge port 23 described above, in this embodiment, the axes of the external feed port 11 and internal feed port 22 coincide with the rotation axis of the switching member 20. That is, both the external feed port 11 and internal feed port 22 are located on the rotation axis of the switching member 20. Thus, even if the switching member 20 rotates, the position of the internal feed port 22 will not change, and the internal feed port 22 can always maintain a proper connection with the external feed port 11. Therefore, there is no need to consider the possibility of misalignment between the external feed port 11 and internal feed port 22 due to the rotation of the switching member 20, ensuring stable and reliable feeding. Of course, similar to the arrangement of the external discharge port 12 and internal discharge port 23 described above, the external feed port 11 and internal feed port 22 can also be arranged in a one-to-many configuration.

[0041] like Figure 2 and Figure 3As shown, in this embodiment, the outer shell 10 adopts a hollow cylindrical structure, and its two ends can be sealed by integral sealing or by cover plates. In this embodiment, the outer shell 10 adopts an integral sealing at one end and a cover plate at the other end, which facilitates the installation of internal components such as the switching component 20. The switching component 20 also adopts a cylindrical structure, and the geometric axis of the outer shell 10 is approximately coincident with the geometric axis of the switching component 20. The external feed inlet 11 and the external discharge outlet 12 are located on opposite sides of the outer casing 10, more specifically, on the end faces of both sides. Similarly, the internal feed inlet 22 and the internal discharge outlet 23 are also located on opposite end faces of the switching member 20. The external feed inlet 11 and the internal feed inlet 22 are located on the end face of the same side of the outer casing 10, while the external discharge outlet 12, the internal discharge outlet 23, and the driving member 30 are located on the end face of the other side of the outer casing 10. In this way, during material conveying, the material is conveyed from one end face of the outer casing 10 into the conveying channel 21 and then conveyed out from the other end face. Moreover, due to the above arrangement, when the conveying channel 21 is curved, its curvature is small, and it is not necessary to have a curvature exceeding 90 degrees, thereby ensuring smooth material conveying. Of course, the specific positions of the above-mentioned openings and driving components 30 can be adjusted as needed. For example, the outer feed port 11, the outer discharge port 12, the inner feed port 22 and the inner discharge port 23 can be set on the same side of the outer casing 10, while the driving component 30 can be set on the other side.

[0042] In this embodiment, the driving component 30 is a motor. Of course, other driving components can also be used. The output shaft of the motor is coaxial with the geometric axis of the switching component 20, and the driving component 30 can be disposed outside the housing 10, thereby realizing the driving component 30 to drive the rotation of the switching component 20.

[0043] like Figure 4As shown, in this embodiment, a gap is provided between the inner wall of the outer shell 10 and the outer wall of the switching component 20, forming a balance channel between them. The outgoing material outlet 12 has a connected state that is connected to the inner material outlet 23 and a non-connected state that is separated from the inner material outlet 23. The outgoing material outlet 12 in the non-connected state is connected to the balance channel. The outer shell 10 has an air inlet 13 that is connected to the balance channel. When conveying material, the air inlet 13 inputs gas to the outgoing material outlet 12 through the balance channel. Specifically, considering that when materials are conveyed through the conveying channel 21, gas will be input into the outgoing outlet 12 that is connected to the inner outlet 23, while the outgoing outlet 12 that is not connected to the inner outlet 23 will be affected by pressure and leak material, this embodiment is provided with a balancing channel and an air inlet 13. The unused outgoing outlet 12 and the air inlet 13 are connected together through the balancing channel, so that when conveying materials, an external device can be used to input gas into the unused outgoing outlet 12 through the air inlet 13 and the balancing channel, so that the unused outgoing outlet 12 and the pipe connected to it maintain positive pressure, achieve the effect of maintaining stable material feeding, and prevent water vapor, oil fumes and other substances caused by the kitchen environment from entering the pipe.

[0044] Optionally, the specific form of the balancing channel can be set as needed, and the position of the air inlet 13 can also be adjusted as needed. For example, the air inlet 13 can be located on the end face or circumferential side wall of the outer casing 10, as long as it can ensure that the air inlet 13 is connected and cooperates with the unused outlet 12 through the balancing channel. In this embodiment, the side surface of the switching member 20 facing the outlet 12 has a protrusion 24 and a first recess 25. That is, the end face of the switching member 20 facing the outlet 12 is not a completely flat surface, but has axial undulations. The surface of the protrusion 24 is basically in close contact with the inner wall of the outer casing 10, and the inner outlet 23 is set at the protrusion 24, so that the inner outlet 23 can maintain a close contact with the specific outlet 12 when the switching member 20 is rotated. The first recess 25, due to its recessed form, naturally forms a space with the inner wall surface of the outer casing 10. The space where the first recess 25 is located serves as at least part of the balancing channel.

[0045] When the air inlet 13 is located on the side where the outlet 12 is located, only the first recess 25 mentioned above is needed to achieve the connection and cooperation between the air inlet 13 and the outlet 12. Considering that the drive unit 30, external pipes and other structures are installed on the side where the outlet 12 is located, in this embodiment, the air inlet 13 is located on the side of the housing 10 away from the outlet 12. That is, the air inlet 13 and the outlet 12 are located on opposite sides of the housing 10, and the air inlet 13 and the external inlet 11 are located on the same side of the housing 10. This facilitates the connection and cooperation between the air inlet 13 and the external equipment. Meanwhile, based on the above-mentioned structural form, in this embodiment, the circumferential side of the switching component 20 and the circumferential inner wall of the outer shell 10 are also separated by a gap to form an annular gap 26. Moreover, similar to the first recessed portion 25, the side surface of the switching component 20 facing the air inlet 13 has an annular second recessed portion 27, and the air inlet 13 is located at the second recessed portion 27. In this way, the first recessed portion 25, the annular gap 26, and the second recessed portion 27 are sequentially connected to form a balance channel, thereby realizing the connection and cooperation between the air inlet 13 and the unused outlet 12.

[0046] In this embodiment, the first recess 25 is set to be relatively large, so that it can simultaneously connect with multiple outlet ports 12. Preferably, all outlet ports 12 not connected with the inner outlet port 23 are connected to the first recess 25, so that gas can be simultaneously input into unused outlet ports 12. With the arrangement of the annular gap 26 and the annular second recess 27, the air inlet 13 can maintain a connection with the second recess 27 regardless of the angle to which the switching member 20 rotates. This ensures that the air inlet 13 can always maintain a connection with the unused outlet ports 12, without having to adjust the position of the air inlet 13 separately due to the rotation of the switching member 20.

[0047] like Figure 2 and Figure 3 As shown, in this embodiment, the cooking appliance feeding device also includes a sealing element 40. The sealing element 40 can be in the form of a sealing ring, sealing gasket, or other structures. The sealing element 40 is disposed between the switching element 20 and the outer shell 10, and seals the circumferential gaps at the joints of the outer feed port 11 and the inner feed port 22, and at the joints of the outer feed port 12 and the inner discharge port 23, preventing material from leaking out from the gaps between the joint surfaces when the feed ports are joined. Specifically, when using gas to transport seasonings, gas needs to be kept flowing into the conveying channel 21. The flow of gas carries the seasonings from the outer feed port 11 to the outer feed port 12. At this time, the conveying channel 21, the outer feed port 11, and the outer feed port 12 need to maintain a good seal to better achieve gas transport. The setting of the sealing element 40 also ensures the sealing of the gas transport pipeline, thus better transporting the seasonings.

[0048] Specifically, multiple sealing elements 40 are provided between the outlet 12 and the inner outlet 23. In this embodiment, two ceramic plates are provided as sealing elements 40 on the end face of the switching element 20 facing the outlet 12. These are a larger fixed sealing element and a smaller movable sealing element. The fixed sealing element is fixedly installed on the inner end face of the outer casing 10 and has a clearance hole corresponding to the outlet 12. The movable sealing element is located on the end face of the protrusion 24 and rotates synchronously with the switching element 20. The movable sealing element also has a clearance hole corresponding to the inner outlet 23. The movable sealing element and the fixed sealing element are tightly fitted together. When the switching element 20 rotates, the movable sealing element rotates with the switching element 20, but the movable sealing element and the fixed sealing element always maintain a tight sealing relationship. Thus, the sealing effect at the outlet 12 and the inner outlet 23 is achieved through the cooperation between the fixed sealing element and the movable sealing element.

[0049] In this embodiment, a sealing ring is provided as a sealing element 40 on the end face of the switching element 20 facing the external feed port 11. Due to the setting of the second recess 27, the central part of the end face of the switching element 20 forms an annular sealing protrusion. The central part of the sealing protrusion has a material conveying channel 21. A stepped structure is formed between the sealing protrusion and the second recess 27, and the sealing ring is sleeved on the stepped structure. The sealing ring protrudes from the end face of the sealing protrusion. When the switching element 20 is installed, a part of the sealing protrusion can be mated with the external feed port 11. At this time, the inner end face of the outer shell 10 and the end face of the switching element 20 cooperate with each other, and the two together squeeze the sealing ring, causing the sealing ring to deform. This makes the sealing ring tightly fit with the surface of the second recess 27 and the inner end face of the outer shell 10, achieving the effect of sealing the gap between the switching element 20 and the outer shell 10.

[0050] Meanwhile, the seals 40 at the external inlet 11 and the external outlet 12 cooperate with each other. Specifically, due to the deformation and compression of the sealing ring at the external inlet 11, when the switching member 20 is connected to the outer shell 10, the seal 40 at the internal inlet 22 compresses the switching member 20, causing the switching member 20 to tend to move towards the end where the external outlet 12 is located. This makes the sealing fit between the fixed seal and the movable seal at the external outlet 12 tighter, further improving the sealing effect.

[0051] Of course, the specific configuration of the above-mentioned sealing element 40 can also be adjusted as needed, as long as reliable sealing can be guaranteed.

[0052] Optionally, the specific material of the seal 40 can be set as needed. In this embodiment, the fixed seal and / or the movable seal are ceramic or ceramic composite parts, while the sealing ring is a rubber part.

[0053] The cooking appliance feeding device of this embodiment also includes a positioning component, which is disposed between the outer shell 10 and the switching member 20. The positioning component plays a positioning and engagement role. When the switching member 20 moves to a predetermined position, the outer shell 10 and the switching member 20 are positioned and engaged by the positioning component, thereby ensuring that the position between the switching member 20 and the outer shell 10 remains stable to a certain extent and preventing accidental rotation. It should be noted that the positioning component does not obstruct the rotation of the switching member 20; its main function is to detect and assist in positioning when the switching member 20 rotates. The specific structural form of the positioning component can be set as needed; this embodiment adopts the following structural form.

[0054] like Figure 2 and Figure 6 As shown, in this embodiment, the positioning component includes a sensed element 50 and a sensor 60. The sensed element 50 is disposed on the switching element 20 and moves synchronously with the switching element 20. The sensor 60 is disposed on the outer casing 10 and can sense the position of the sensed element 50 to determine the position of the switching element 20. In this embodiment, the sensed element 50 is a magnet, and the sensor 60 is a Hall element. The Hall element can sense the position of the magnet, thereby determining the rotation angle of the switching element 20 based on the position of the magnet, and thus obtaining the docking state of the inner discharge port 23, realizing the monitoring of the discharge position. In this embodiment, a sensed element 50 is disposed on the switching element 20, and a sensor 60 is disposed at each discharge port 12. When the sensor 60 detects the sensed element 50, it indicates that the discharge port 12 corresponding to the sensor 60 is discharging material. At the same time, the cooperation between the sensor 60 and the sensed element 50 can also play a role in initial positioning. By adjusting the positions of the sensed element 50 and the sensor 60, the inner discharge port 23 is docked with an discharge port 12 when they are aligned. Of course, the sensing element 50 and the sensing element 60 can also be other components. The number and position of the two can be adjusted as needed. For example, only one sensing element 50 and one sensing element 60 can be set. After the initial positioning, the driving angle of the driving element 30 can be controlled by the circumferential arrangement angle between the outgoing material outlets 12 to achieve the effect of accurate switching of the inner material outlet 23 between each outgoing material outlet 12.

[0055] like Figure 5As shown, in this embodiment, the positioning component further includes a ball bearing 70 and an elastic element 80. In this embodiment, the ball bearing 70 and the elastic element 80 are disposed on the end face of the switching member 20 facing the outer feed port 11. Specifically, the ball bearing 70 is movably disposed within the housing 10, and an arc-shaped groove is provided on the protrusion of the switching member 20. The groove can accommodate part of the ball bearing 70, thereby allowing the ball bearing 70 to extend into or retract from the switching member 20. The elastic element 80 can be a component such as a spring, which is embedded in the housing 10, with one end abutting against the housing 10 and the other end abutting against the ball bearing 70, thereby providing the ball bearing 70 with the elastic force to extend into the switching member 20. The ball bearing 70 and the elastic element 80 work together to provide auxiliary positioning. When the switching element 20 rotates under the drive of the drive element 30, the groove squeezes and pushes the ball bearing 70, causing it to exit the groove. At this time, the switching element 20 can rotate smoothly. The groove, under the action of the elastic element 80, will abut against the end face of the switching element 20, but it will not significantly affect the rotation of the switching element 20. When the switching element 20 moves to the predetermined position, that is, when the inner discharge port 23 and the outer discharge port 12 are aligned, the ball bearing 70 and the groove are also aligned. At this time, the ball bearing 70 can extend into the groove under the action of the elastic element 80, thus achieving the auxiliary positioning function. It should be noted that the ball bearing 70 only provides auxiliary positioning and has virtually no impact on the rotation of the switching element 20.

[0056] This embodiment also provides a cooking appliance feeding control method. Using the above-mentioned cooking appliance feeding device, the cooking appliance feeding control method includes: a driving member 30 driving a switching member 20 to move, causing the inner outlet 23 of the switching member 20 to change the docking outlet 12; during the movement of the switching member 20, the driving member 30 first drives the switching member 20 to move with a first driving force, and after the switching member 20 has moved for a predetermined time, the driving member 30 then drives the switching member 20 to continue moving with a second driving force, wherein the first driving force is greater than the second driving force.

[0057] The reason for adopting the above-described control method in this embodiment is that when the switching component 20 switches to the outlet 12, it initially requires a larger force, but the force required for subsequent rotation is smaller. Specifically, due to the structure of the ball bearing 70, the initial rotation of the switching component 20 requires pushing the ball bearing 70 out of the groove. Therefore, in use, the driving component 30 can be controlled to first use a larger first driving force to drive the switching component 20 to overcome the resistance of the ball bearing 70 being squeezed and rotate. After the switching component 20 has moved for a predetermined time, the ball bearing 70 has already exited the groove. Then, a smaller second driving force is used to drive the switching component 20 to rotate until the switching component 20 rotates to the correct position and the ball bearing 70 is stuck when it enters another groove. The control process of the driving component 30 is coordinated with the detection of the sensing component 60. Therefore, in this embodiment, the sensing component 60 and the driving component 30 are provided with a signal connection to achieve their coordinated operation. In this embodiment, the driving force is achieved by controlling the power of the driving component 30.
