Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and in particular to the structure of grease delivery pipes and cooking equipment. Background Technology

[0002] As living standards improve, people are paying more and more attention to cooking efficiency, leading to the emergence of various automatic / semi-automatic cooking equipment to enhance the automation and ease of operation of cooking. Currently, cooking equipment generally uses oil delivery pipes to add lard, vegetable oil, and other fats to meet the oil requirements of different dishes. However, in actual use, due to the high viscosity and solidification properties of oils, especially at low temperatures, oils are prone to solidification inside the delivery pipes, causing poor delivery or even blockage, affecting the continuity and stability of the cooking process.

[0003] In related technologies, the oil delivery pipe is placed outside the cooking equipment, and a heating tape is wrapped around the oil delivery pipe to prevent the oil from solidifying during transportation.

[0004] However, in the process of transporting grease, the oil delivery pipe in the relevant technology is prone to shaking, which can cause the grease to deviate from the delivery position and spill out, resulting in grease waste and increasing the difficulty of cleaning the cooking equipment.

The oil delivery pipe structure installs an oil delivery pipe inside the cooking device, with an oil guide pipe at the outlet end of the oil delivery pipe. A heating element is installed on the oil guide pipe. The cooking device supports the oil delivery pipe, and the heating element heats the oil guide pipe. This ensures the fluidity of the oil while preventing the external oil delivery pipe from shifting due to shaking, thus preventing oil spillage, waste, and contamination of the pot exterior, and improving the accuracy of oil dispensing. Furthermore, since the oil delivery pipe is installed inside the cooking device, no additional support structure is needed, improving the overall structural compactness.

[0042] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0043] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that the terms "upper," "lower," "horizontal," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In this application, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0045] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two entities at the point of connection are not connected through a transitional structure, but are simply linked together to form a whole. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0046] In this application, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0047] As living standards improve, people are paying more and more attention to cooking efficiency, leading to the emergence of various automatic / semi-automatic cooking equipment to enhance the automation and ease of operation of cooking. Currently, cooking equipment generally uses oil delivery pipes to add lard, vegetable oil, and other fats to meet the oil requirements of different dishes. However, in actual use, due to the high viscosity and solidification properties of oils, especially at low temperatures, oils are prone to solidification inside the delivery pipes, causing poor delivery or even blockage, affecting the continuity and stability of the cooking process.

[0048] In related technologies, the oil delivery pipe is placed outside the cooking equipment, and a heating tape is wrapped around the oil delivery pipe to prevent the oil from solidifying during transportation.

[0049] However, this technology has significant limitations: during the oil delivery process, the oil pipe is prone to swaying, causing the oil to deviate from its designated placement position and spill out, resulting in oil waste and increasing the difficulty of cleaning the cooking equipment. Furthermore, because the heating element is wrapped around the oil pipe, the pipe becomes thicker and harder, making it difficult to integrate and install within the cooking equipment, and difficult to support the overall structure of the oil pipe using the cooking equipment. Therefore, to prevent the oil pipe from swaying and spilling during delivery, an additional support structure must be installed to support and secure the oil pipe. This additional support structure increases manufacturing costs and occupies a significant amount of space.

[0050] To address the aforementioned issues, this application provides an oil delivery pipe structure. This structure integrates an oil delivery pipe 1 inside a cooking appliance 3. An oil guide pipe 2 is installed at the outlet end of the oil delivery pipe 1, and a heating element is mounted on the oil guide pipe 2. The cooking appliance 3 supports the oil delivery pipe 1, and the heating element heats the oil guide pipe 2. This ensures the fluidity of the oil while preventing the external oil delivery pipe 1 from shifting due to movement, thus preventing oil spillage, waste, and contamination of the pot body 34, and improving the accuracy of oil dispensing. Furthermore, since the oil delivery pipe 1 is installed inside the cooking appliance, no additional support structure is needed, improving the overall structural compactness.

[0051] Reference Figure 1 and Figure 2 In some embodiments, an oil delivery pipe structure can be applied to cooking equipment 3, which may be a stir-fry machine, a smart stew pot, an automatic noodle cooker, or other cooking equipment 3 that requires multi-pipe feeding. This application does not impose specific limitations on this.

[0052] The grease delivery pipe structure may include a delivery pipe 1, a guide pipe 2, and a heating element. The delivery pipe 1 is used to deliver grease and is installed inside the cooking equipment 3 to support it and improve its stability. The guide pipe 2 is connected to the outlet end of the delivery pipe 1, and at least a portion of the guide pipe 2 is located outside the cooking equipment 3, with its outlet end facing the feeding area on the cooking equipment 3. The heating element is disposed on the outer periphery of the guide pipe 2 and is used to heat the guide pipe 2 to ensure the fluidity of the grease at the guide pipe 2, thereby preventing the grease from solidifying and clogging the guide pipe 2 at low temperatures.

[0053] It should be noted that the oil transported by the oil pipe 1 can be lard, vegetable oil or other animal fats, and can be selected according to actual cooking needs. This application does not impose any specific restrictions on this.

[0054] It should also be noted that the heating element can be a heating belt or an electric heating wire, which can be selected and set according to actual needs. The goal is to ensure that the heating element heats the grease in the oil guide pipe 2, preventing the grease from solidifying and clogging at low temperatures, thereby ensuring the continuity and stability of grease delivery. This application does not impose specific limitations on the type of heating element. The heating element can be wrapped around the outer circumference of the oil guide pipe to achieve partial or full heating of the grease delivery path. The wrapping range of the heating element can be set uniformly or in segments according to the length and diameter of the oil guide pipe 2, ensuring that the grease in the oil guide pipe 2 is heated uniformly by the heating element.

[0055] It is understood that the oil pipeline 1 and the oil guide pipeline 2 can be connected by welding, threaded connection or flange connection, etc., and the selection and setting can be made according to actual needs. This application does not impose specific restrictions on this.

[0056] For example, the oil delivery pipe 1 and the oil guide pipe 2 are connected by a threaded connection. The oil delivery pipe 1 and the oil guide pipe 2 are detachable, which is convenient for disassembly and replacement. This is suitable for scenarios where there is a lot of grease residue during the use of the grease delivery pipe structure.

[0057] It should also be noted that the oil guide pipe 2 can be entirely located outside the cooking device 3, ensuring that the oil is transported from the outlet end of the oil guide pipe 2 to the feeding area on the cooking device 3. In this case, no additional installation space is required to install the oil guide pipe 2. The oil guide pipe 2 can also be partially located outside the cooking device 3. For example, the oil guide pipe 2 can be partially embedded in the cooking device 3 to facilitate the feeding of oil.

[0058] Reference Figure 1 and Figure 2 In some embodiments, the oil guide 2 may include: a horizontal section 21 (see...) Figure 1(x direction in the middle) and vertical segment 22 (see Figure 1 (in the y direction). The horizontal section 21 is connected to the outlet end of the oil supply pipe 1 to smoothly guide the oil from the oil supply pipe 1 to the vertical section 22. The vertical section 22 is connected to the outlet end of the horizontal section 21, and the side of the vertical section 22 away from the horizontal section 21 faces the feeding area on the cooking device 3, so as to facilitate the feeding of oil with the help of gravity and prevent the oil feeding position from deviating, causing waste or contamination of the cooking device 3.

[0059] Reference Figure 1 and Figure 2 In some embodiments, the horizontal segment 21 and the vertical segment 22 can be configured as integrally formed structural components to avoid oil leakage or blockage problems in the horizontal segment 21 and the vertical segment 22.

[0060] Understandably, in order to improve the overall structural strength of the oil guide pipe and simplify the assembly process, while preventing grease from leaking or accumulating and clogging at the connection points, the horizontal section 21 and the vertical section 22 can be set as an integrally formed L-shaped oil guide pipe, thereby avoiding assembly errors, poor sealing or grease residue problems caused by the split connection structure.

[0061] It is also understandable that the horizontal section 21 and the vertical section 22 are connected by a rounded transition section to reduce the flow resistance of grease inside the oil guide pipe 2, avoid grease retention or blockage caused by bending at the connection between the horizontal section 21 and the vertical section 22, and further improve the smoothness of grease delivery.

[0062] Reference Figure 1 and Figure 2 In some embodiments, there is an angle between the horizontal segment 21 and the vertical segment 22, and the angle can range from 85° to 95°.

[0063] It should be noted that the included angle between the horizontal section 21 and the vertical section 22 can be 85°, 90° or 95°, depending on the location of the feeding area, the viscosity of the grease, etc., as long as the grease flows out smoothly and does not cause backflow or blockage. This application does not impose specific restrictions on this.

[0064] Reference Figure 1 and Figure 2 In some embodiments, the grease delivery pipe structure may further include a protective layer. The protective layer covers the outer periphery of the oil delivery pipe 1 to enhance the wear resistance and high temperature resistance of the oil delivery pipe 1, prevent external scratches or high temperature environments from damaging the oil delivery pipe 1, thereby extending the service life of the oil delivery pipe 1.

[0065] It should be noted that the protective layer can be a metal spring tube, a metal braided sleeve, a silicone sleeve, or a high-temperature resistant plastic sleeve, and the choice can be made according to actual needs. This application does not impose specific restrictions on this. For example, the protective layer can be a metal spring tube, which covers the outer periphery of the oil pipeline. This enhances the wear resistance of the oil pipeline 1 while giving it a certain degree of elasticity and expansion capacity to accommodate the free expansion and contraction of the oil pipeline 1 during the movement of the cantilever 33, thereby preventing damage or breakage of the oil pipeline 1.

[0066] It is understandable that, in order to achieve elastic expansion and contraction of the oil pipeline 1 within the metal spring tube, the inner diameter of the metal spring tube is larger than the outer diameter of the oil pipeline 1, so that the oil pipeline 1 can slide freely along the axial direction inside the metal spring tube.

[0067] Reference Figure 1 and Figure 2 In some embodiments, a nozzle may be provided at the outlet end of the oil supply pipe 1. The nozzle is connected to both the oil supply pipe 1 and the oil guide pipe 2 to achieve concentrated spraying of grease, improve the feeding accuracy of grease, and reduce waste.

[0068] Understandably, the nozzle's outlet can be designed as a conical or tapered structure to increase the grease injection pressure and achieve more uniform and precise grease delivery.

[0069] Reference Figure 1 and Figure 2 This application also provides a cooking device 3, which can adopt the above-mentioned oil conveying pipe structure to achieve stable oil conveying and precise delivery, improve oil utilization, and reduce the cleaning difficulty of the cooking device 3.

[0070] Reference Figures 3 to 5 In some embodiments, the cooking device 3 may further include a pot body 34. The pot body 34 has a cooking cavity, and the outlet end of the oil guide pipe 2 in the oil delivery pipe structure faces the cooking cavity.

[0071] Reference Figures 3 to 5 In some embodiments, the cooking device 3 may further include a support structure. The support structure is connected to the pot body 34 to support and secure the pot body 34.

[0072] Reference Figure 2 and Figure 3 In some embodiments, the cooking apparatus 3 may further include an oil supply system. The oil supply system is connected to the oil delivery pipe 1 in the grease delivery pipe structure, and the oil supply system is used to supply grease to the oil delivery pipe 1.

[0073] For example, the oil supply system can be a grease pumping device, which can include an oil storage tank and a booster pump, through which the booster pump transports the grease in the oil storage tank to the oil pipeline 1.

[0074] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, the support structure may include a column 32 and a cantilever 33. A lid 31 is provided on the pot body 34 to cover the cooking cavity, and the outlet end of the oil guide pipe 2 extends through the lid 31 into the cooking cavity. One side of the cantilever 33 is connected to the lid 31, and the other side of the cantilever 33 is rotatably connected to the column 32.

[0075] It should be noted that the cantilever 33 can be rotatably connected to the column 32 through a rotating shaft, bearing or hinge structure, so as to realize the rotational movement of the cantilever 33 relative to the column 32, thereby driving the pot lid 31 to open or close the cooking chamber, while ensuring the stability and sealing of the oil supply pipe 1 during the movement of the cantilever 33.

[0076] For example, a fixed shaft 35 is fixedly installed on the end of the column 32 near the cantilever 33. The cantilever 33 is rotatably sleeved on the fixed shaft 35, so that the cantilever 33 can rotate around the column 32. The cantilever 33 drives the pot lid 31 to open or close, thereby realizing the opening and closing of the cooking cavity.

[0077] Reference Figure 5 and Figure 6 In some embodiments, a clearance hole may be provided at the connection between the cantilever 33 and the column 32, through which the oil supply pipe 1, which is connected to the oil supply system, extends into the cantilever 33. With this configuration, the oil supply pipe 1 can enter the cantilever 33 from inside the column 32 through the clearance hole, thereby achieving stable oil delivery and preventing the oil supply pipe 1 from being exposed, thus improving the compactness and aesthetics of the overall structure.

[0078] Reference Figure 5 and Figure 6 In some embodiments, an elastic element may be provided inside the clearance hole. With this configuration, the elastic element can guide, buffer, and seal the oil pipe 1, allowing the oil pipe 1 to move freely during the rotation of the cantilever 33, avoiding bending, pulling, or oil leakage of the oil pipe 1 due to the movement of the cantilever 33, and improving the stability and service life of the grease delivery structure.

[0079] It should be noted that the elastic element can be a soft rubber plug, a silicone sealing ring, a rubber gasket, or an elastic bellows. For example, the elastic element is set as a soft rubber plug to provide guidance and cushioning when the oil pipe 1 moves with the cantilever 33, while maintaining a seal to prevent grease leakage or the entry of external impurities.

[0080] It should also be noted that the inner diameter of the elastic element is larger than the diameter of the oil pipe 1, so that the oil pipe 1 can move freely inside the elastic element during the rotation or swing of the cantilever 33, and avoid the oil pipe 1 from bending, jamming or being pulled and damaged due to motion interference.

[0081] Reference Figure 5 and Figure 6 In some embodiments, the support structure may further include a guide fixing member. The guide fixing member is located inside the cantilever 33, with one end fixedly connected to the cantilever 33 and the other end movably connected to the oil delivery pipe 1 extending into the cantilever 33, so as to achieve the fixation and elastic support of the oil delivery pipe 1 inside the cantilever 33, so that the oil delivery pipe 1 can freely extend and retract along the axial direction during the rotation of the cantilever 33, while preventing the oil delivery pipe 1 from shifting, shaking or falling off due to vibration or external force, thereby improving the stability of grease delivery.

[0082] It should be noted that the guide fixing component can be a guide groove, a snap-fit ​​structure, or an elastic clamping component, etc.

[0083] For example, the guide fixing component is an elastic clamping component. One end of the elastic clamping component is fixed to the inner wall of the cantilever 33 by a screw, and the other end has an elastic clamping part for clamping the oil pipe 1. The elastic clamping part allows the oil pipe 1 to slide freely during the rotation of the cantilever 33, while preventing the oil pipe 1 from shaking or falling off. Specifically, the elastic clamping component can be a U-shaped elastic clamping structure. The U-shaped elastic clamping structure includes a U-shaped body and elastic arms disposed at both ends of the U-shaped body. One end of the U-shaped body is fixedly connected to the inner wall of the cantilever 33 by a screw or rivet. The elastic arms at the other end of the U-shaped body are arranged opposite each other to form a clamping space. The clamping space is used to clamp the oil pipe 1 and allows the oil pipe 1 to slide freely along the axial direction inside the clamping space.

[0084] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
