An easy-to-clean sausage tube and its grilling machine

Abstract

This utility model discloses an easy-to-clean sausage tube and barbecue machine, including a tube body, an insert, and a rotating shaft. The inner wall of the tube body is provided with continuous spiral protrusions, which protrude radially along the inner wall of the tube body and extend spirally along the axial direction of the tube body. The two ends of the spiral protrusions extend to both ends of the tube body. The insert also has drain holes for draining liquid from the tube. This utility model can induce the cleaning liquid to rotate and flow on the spiral protrusions, generating centrifugal force to remove oil stains and guide the accumulated liquid to the drain holes at both ends of the tube body for discharge. The internal liquid can be fully drained by manually shaking the sausage tube, or the sausage tube can be placed on the barbecue machine and rotated at a relatively high speed to ensure thorough cleaning. Therefore, this utility model solves the problem of insufficient cleaning of sausage tubes in previous barbecue machines, avoids bacterial growth caused by long-term oil accumulation, and ensures food safety.

Description

Technical Field

[0001] This utility model relates to the field of household appliances and kitchenware, specifically to an easy-to-clean sausage tube, and a barbecue machine including such an easy-to-clean sausage tube. Background Technology

[0002] Sausages, hot dogs, and similar flavored foods are primarily cooked using sausage grilling machines. The main working principle of a sausage grilling machine is as follows: an internal drive motor controls multiple cylindrical grilling tubes to rotate at a constant speed. The sausage is placed in the gap between two adjacent grilling tubes, where it is supported by the two tubes. The rotation of the grilling tubes causes the sausage to rotate at a constant speed, continuously turning it over. Simultaneously, the heating elements inside the machine heat the sausage, thus cooking it.

[0003] Due to the composition of sausages, they contain a large amount of oil and meat. During heating, the sausage continuously releases oil, which flows and drips along the surface of the grilling tube. Although the grilling tube could be made into a solid, sealed structure, the drive motor needs to continuously rotate multiple tubes. Since sausage grilling machines are portable small devices (often used at mobile stalls, family gatherings, etc.), solid, heavy tubes would significantly increase the load and energy consumption. Therefore, using hollow tubes would be more beneficial in reducing load and energy consumption. However, under prolonged use, oil inevitably seeps into the interior of the grilling tubes, and moisture generated by heating cannot escape in time. Once the oil seeps into the tubes, it forms stubborn grease and grime over time, easily breeding large amounts of bacteria, compromising food safety and potentially endangering health. Even after rinsing the grilling tubes, the liquid inside is difficult to drain completely, resulting in incomplete cleaning.

[0004] Therefore, the cleaning of sausage tubes remains a pressing issue in the sausage grilling equipment industry. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, one objective of this utility model is to provide an easy-to-clean sausage tube, and another objective is to provide a barbecue machine that includes such a sausage tube, which can solve the problem that existing sausage tubes are difficult to clean completely.

[0006] This utility model is achieved through the following technical solution:

[0007] An easy-to-clean sausage tube includes: a tube body, an insert, and a rotating shaft; the tube body is a hollow structure with a hollow cavity inside, and the two ends of the hollow cavity are through holes; the insert is fitted into both ends of the tube body, and the rotating shaft is fixedly connected to the insert so that the rotating shaft drives the insert and the tube body to rotate; the inner sidewall of the tube body is also provided with a continuous spiral protrusion, the spiral protrusion protruding along the radial direction of the inner sidewall of the tube body and extending spirally along the axial direction of the tube body, with both ends of the spiral protrusion extending to both ends of the tube body; the insert is also provided with a drain hole for draining liquid from the tube.

[0008] Furthermore, the inner wall of the tube is machined with a number of raised spherical protrusion structures, which are evenly spaced apart.

[0009] Furthermore, the surface of the spiral protrusion is also recessed with a spiral shallow groove, which is a long groove structure, and the spiral shallow groove extends along the direction of the spiral protrusion.

[0010] Furthermore, the spiral protrusion is uniformly coated with a hydrophobic coating.

[0011] Furthermore, the hydrophobic coating is a PTFE layer.

[0012] Furthermore, the insert is also provided with mounting holes for connecting the rotating shaft; there are two drainage holes, which are located on both sides of the mounting holes.

[0013] Furthermore, the insert is detachably fitted to both ends of the tube.

[0014] Furthermore, the rotating shaft is a square shaft structure, and the mounting hole of the insert is a matching square hole structure; the rotating shaft is inserted into the square hole structure to drive the insert to rotate.

[0015] Furthermore, the insert is a silicone insert.

[0016] A barbecue grill, comprising the aforementioned easy-to-clean sausage tube.

[0017] Compared with existing technologies, the beneficial effects that this utility model can achieve are as follows:

[0018] When cleaning the sausage tube, its surface can be rinsed (or it can be soaked in cleaning solution). After cleaning, the liquid inside the tube can be drained through the drain holes at both ends. During the drainage process, the continuous spiral protrusions inside the tube extend axially along the inner wall of the tube, inducing the cleaning solution to rotate and flow on the spiral protrusions, generating centrifugal force, and shaking off the oil stains, guiding the liquid to the drain holes at both ends of the tube for discharge. When the oil stains are small or thin, the internal cleaning liquid can be fully drained by manually shaking the sausage tube. When the oil stains are large and the accumulation layer is thick, after rinsing or soaking, the sausage tube can be placed on a sausage grilling machine and rotated at a relatively high speed. The output rotation of the sausage grilling machine will then fully shake out the cleaning liquid inside the tube, thus ensuring that both the exterior and interior of the sausage tube are thoroughly cleaned. Therefore, this invention solves the problem of insufficient cleaning of sausage tubes in previous barbecue machines, avoids bacterial growth caused by long-term oil stain accumulation, and ensures food safety.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this utility model, it should be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] See Figures 1-5 This utility model discloses an easy-to-clean sausage tube, which is used in barbecue equipment such as sausage grilling machines. Figure 6 .

[0031] See Figures 1-5This utility model includes: a tube body 10, an insert 20, and a rotating shaft 30. The tube body 10 is a hollow tube with an internal hollow cavity and through holes at both ends. The insert 20 is fitted into the through holes at both ends of the tube body 10, and the rotating shaft 30 is fixedly connected to the insert 20. Thus, the rotating shaft 30, insert 20, and tube body 10 are relatively fixed in the radial direction, allowing the rotating shaft 30 to drive the tube body 10 to rotate. It can be understood that the rotating shaft 30 is also connected to the rotating mechanism of the equipment, such as a rotary drive module consisting of a rotating gear and a drive motor. The sausage 40 is placed in the gap between two adjacent sausage tubes, supported by the two sausage tubes. The sausage 40 is rotated evenly and flipped by the rotation of the sausage tubes. The tube body 10 has a continuous spiral protrusion 11 on its inner wall. The spiral protrusion 11 protrudes radially along the inner wall of the tube body 10 in the height direction and extends spirally along the axial direction of the tube body 10 in the length direction. The two ends of the spiral protrusion 11 extend to the two ends of the tube body 10, respectively. The insert 20 also has a drain hole 21 for draining liquid from the tube, and the two ends of the spiral protrusion 11 are close to the drain hole 21.

[0032] When cleaning the sausage tube is necessary, its surface can be rinsed (or it can be soaked in cleaning solution). After cleaning, the liquid inside the tube can be drained through the drain holes 21 at both ends. During the drainage process, the continuous spiral protrusions 11 inside the tube extend axially along the inner wall of the tube body 10, inducing the cleaning solution to rotate and flow on the spiral protrusions 11, generating centrifugal force, and removing oil stains, guiding the liquid to the drain holes 21 at both ends of the tube body 10 for discharge. When the oil stains are small or thin, the internal cleaning liquid can be fully drained by manually shaking the sausage tube. When there are many oil stains and the accumulation layer is thick, after rinsing or soaking, the sausage tube can be placed on a sausage roasting machine and rotated at a relatively high speed, so that the cleaning liquid inside the tube can be fully shaken out by the output rotation of the sausage roasting machine. In this way, both the exterior and interior of the sausage tube are thoroughly cleaned. Therefore, this invention solves the problem of insufficient cleaning of the sausage tubes in previous barbecue machines, avoids bacterial growth caused by long-term oil accumulation, and ensures food safety.

[0033] To further enhance drainage performance, preferably, refer to Figures 3-5 Several raised spherical protrusion structures 13 are also machined on the inner wall of the pipe body 10. The spherical protrusion structures 13 are evenly distributed at a certain interval. By setting regular micro-protrusions, the laminar flow can be disrupted and the local turbulence can be enhanced, thereby improving the turbulence effect, avoiding the accumulation of cleaning fluid in the pipe, and making the liquid easier to be thrown off.

[0034] To further enhance drainage performance, preferably, refer to Figures 3-5Furthermore, a shallow spiral groove 12 can be protruded on the surface of the spiral protrusion 11. The shallow spiral groove 12 is a long, narrow groove structure with a shallow depth, similar to rifling. The spiral grooves run in the same direction as the spiral protrusion 11. By machining shallow grooves on the spiral protrusion 11, the cleaning fluid on the spiral protrusion 11 can be induced to rotate and flow, further reducing the adsorption force of the accumulated fluid on the spiral protrusion 11, thus making it easier to remove the cleaning fluid from the pipe.

[0035] Preferably, a hydrophobic coating can also be applied to the spiral protrusion 11 to increase its hydrophobicity and prevent liquid from accumulating on the spiral protrusion 11. Specifically, the hydrophobic coating should be made of a material with good heat resistance and strong chemical stability, such as a PTFE coating.

[0036] Specifically, see Figures 1-2 The number of drainage holes 21 can be set to two. The insert 20 also has mounting holes for connecting the rotating shaft 30, with the drainage holes 21 located on both sides of these mounting holes. Of course, the number of drainage holes 21 can also be set to other specific quantities, which can be set as needed without specific limitations.

[0037] Preferably, the insert 20 and the tube body 10 are detachably connected, with the insert 20 detachably fitted onto both ends of the tube body 10. This allows the insert 20 to be removed from both ends of the tube body 10 for direct flushing of the interior of the tube body 10, separate cleaning of the insert 20, or direct replacement with a new insert 20. More specifically, the insert 20 can be made of silicone material, facilitating a tight fit onto the ends of the tube body 10 and a tight wrap around the rotating shaft 30.

[0038] Preferably, the rotating shaft 30 is a square shaft, and the mounting hole of the insert 20 is a matching square hole structure. The rotating shaft 30 is inserted into the square hole structure, so that the rotational motion of the rotating shaft 30 can be stably transmitted to the insert 20 and the tube 10.

[0039] See Figure 6 This utility model also discloses a barbecue grill, including the aforementioned easy-to-clean sausage tube. Any barbecue grill that uses the same or substantially the same sausage tube should be within the protection scope of this utility model.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
