Description

Technical Field

[0001] The utility model relates to the technical field of food machinery, and particularly relates to an automatic dripping mechanism for liquid sauce of a barbecue machine. Background Art

[0002] An automatic barbecue machine generally refers to a device that can automatically control the barbecue process and is usually used for barbecuing food. These devices can have multiple functions, such as setting the barbecue time and temperature, automatically turning the food for even cooking, monitoring the doneness of the food, and sprinkling ingredients. During the operation of an automatic barbecue machine, evenly and accurately dripping liquid sauce is a necessary baking step. However, many liquid sauces, such as cooking oil, are highly flammable. During the spraying process, if the cooking oil is atomized and combined with the high temperature of the barbecue furnace, dangerous situations such as rapid deflagration will occur. If oil, sauce, water, etc. in the pipeline produce backflow or leakage, it will cause problems such as waste and hygiene, and form an empty pipeline. When spraying is required again, it cannot meet the requirements of timely and accurate dripping. Content of the Utility Model

[0003] The purpose of the utility model is to provide an automatic dripping mechanism for liquid sauce of a barbecue machine to solve the problems that the current spraying of liquid sauce is prone to dangerous situations such as deflagration, and the pipeline will have backflow or leakage to form an empty pipeline, affecting the re-dripping of the sauce.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: An automatic dripping mechanism for liquid sauce of a barbecue machine includes a confluence pipe, a branch pipe, and a sauce pump for transporting liquid sauce to the confluence pipe. The branch pipe includes a check pipe, a shunt pipe, and a dripping pipe that are connected in sequence from top to bottom. A check member is provided at the check pipe, and when the dripping of liquid sauce stops, the liquid sauce is kept in the branch pipe under the action of atmospheric pressure.

[0005] Principle of this scheme: The sauce pump pressurizes and transports the liquid sauce to the confluence pipe, and then the liquid sauce enters the check pipe, the shunt pipe, and the dripping pipe in sequence from the confluence pipe and drips from the dripping pipe; after dripping is completed, the check member is used to control the disconnection between the confluence pipe and the check pipe to ensure no waste and no messy dripping causing cleaning problems; to avoid the empty pipe phenomenon caused by liquid backflow, when spraying again, oil, sauce, water, etc. can be dripped in time to meet the requirements of timely and accurate dripping. At the same time, the liquid sauce has a certain viscosity, and the inner diameter of the dripping pipe is usually small, making it difficult for the liquid sauce to flow, reducing the occurrence of liquid sauce dripping.

[0006] Advantages of this scheme: This scheme drips through the dripping pipe, avoiding the deflagration risk caused by the atomization of flammable liquid sauce spraying and preventing deflagration accidents; at the same time, the check member is used to timely control the disconnection between the check pipe and the confluence pipe to ensure no waste and no messy dripping causing cleaning problems, avoiding the empty pipe phenomenon caused by liquid backflow, and when spraying again, oil, sauce, water, etc. can be dripped in time to meet the requirements of timely and accurate dripping.

[0007] Preferably, the check member includes a solenoid valve for controlling the connection and disconnection between the check pipe and the manifold pipe. The connection and disconnection between the check pipe and the manifold pipe are controlled by controlling the solenoid valve switch.

[0008] Preferably, the check member includes a steel ball. A check section is connected in series on the check pipe. The check section is located above the manifold pipe and the flow direction of the liquid slurry inside is upward. The check section is in an inverted conical shape, and the steel ball is located inside the conical section of the check pipe. After stopping the dripping of the liquid sauce, since the steel ball is located above the manifold pipe, the steel ball will naturally fall and block the check section, disconnecting the connection between the manifold pipe and the shunt pipe.

[0009] Preferably, the shunt pipe is transparent, so that it is convenient to observe whether there is sauce.

[0010] Preferably, a bracket is further included. The manifold pipe is arranged on the bracket, and the manifold pipe is installed and fixed through the bracket.

[0011] Preferably, a material spreading chamber is provided inside the bracket. A material spreading mechanism for spraying solid seasonings is installed in the material spreading chamber, and a material spreading port is provided at the bottom of the material spreading chamber. Solid seasonings and liquid sauces can be added, which is more convenient for users to use.

[0012] Preferably, the cross-section of the bracket is V-shaped. The solid seasonings in the material spreading chamber converge at the material spreading port at the bottom, which is convenient for sprinkling solid seasonings on the skewers.

[0013] Preferably, the opening position of the dripping pipe is matched with the position of the material spreading port, so as to facilitate sprinkling solid seasonings and liquid sauces on the barbecue skewers respectively.

[0014] Preferably, a baffle for controlling the distance between the dripping pipe and the bracket is further provided on the bracket. The distance between the dripping pipe and the bracket is controlled by the baffle, and the cleaning dead angle of the bracket is minimized as much as possible, which is convenient for cleaning the bracket and the dripping pipe.

[0018] Figure 3 It is a schematic structural diagram of the manifold pipe and the check pipe with a steel ball in Embodiment 2 of the present invention. Detailed Description of the Invention

[0019] The following is a further detailed description through specific embodiments:

[0020] The reference numerals in the accompanying drawings of the specification include: a manifold 1, a check valve pipe 2, a shunt pipe 3, a drip pipe 4, a baffle 5, and a bracket 6.

[0021] Embodiment 1:

[0022] An automatic drip mechanism for liquid sauce of a barbecue machine, as shown in the attached... Figure 1 and the attached... Figure 2 shown, includes a manifold 1, a branch pipe, and a sauce pump (not shown in the figure) for delivering liquid sauce to the manifold 1. The sauce pump pressurizes and delivers the liquid sauce to the manifold 1, and then the liquid sauce is discharged from the manifold 1 and the branch pipe. The liquid sauce includes oil, sauce, water, etc. By adjusting the pressurization amount of the sauce pump, it is ensured that the liquid sauce such as oil and self-prepared sauce is in a dripping mode, avoiding the risk of deflagration and ensuring the accurate dripping amount.

[0023] The branch pipe includes: a check valve pipe 2, a shunt pipe 3, and a drip pipe 4 that are connected in sequence from top to bottom. The check valve pipe 2 is an inverted U-shaped pipe. After the check valve pipe 2 is connected to the manifold 1, a part of the check valve pipe 2 is located above the manifold 1.

[0024] A check member is provided at the check valve pipe 2, and under the action of atmospheric pressure, the liquid sauce is kept in the branch pipe when the dripping of the liquid sauce stops. In this embodiment, the check member includes an electromagnetic valve, which is used to control the connection and disconnection between the check valve pipe 2 and the manifold 1. After the dripping of oil, sauce, water, etc. ends, when the electromagnetic valve stops the dripping of the liquid in time, it ensures that there is no waste and no messy dripping causing cleaning problems; it avoids the phenomenon of an empty pipe caused by liquid backflow, and can drip oil, sauce, water, etc. in time when spraying again, meeting the requirements of timely and accurate dripping.

[0025] Among them, the shunt pipe 3 is transparent, which is convenient for observing whether there is sauce. In this embodiment, the shunt pipe 3 is a transparent flexible pipe, which is convenient for connecting the check valve pipe 2 and the dripping pipe 4. The inner diameters of the dripping pipe 4 and the check valve pipe 2 are both smaller than the inner diameter of the shunt pipe 3, and the inner diameter of the dripping pipe 4 is smaller than the diameter of the shunt pipe 3. In this embodiment, since the liquid sauce has a certain viscosity, the diameter of the dripping pipe 4 is usually relatively small. When the diameter of the dripping pipe 4 is small, when the high-viscosity liquid flows in the thin pipe, the internal friction and the friction with the pipe wall are both large, and the flow becomes more difficult, avoiding the empty pipe phenomenon caused by the natural dripping of the liquid sauce due to gravity when the liquid sauce stops dripping. When spraying again, oil, sauce, water, etc. can be dripped in time, meeting the requirements of timely and accurate dripping. In this embodiment, the dripping pipe 4 is preferably a thin pipe such as a capillary tube. When the liquid enters the capillary tube, due to the action of surface tension, the liquid molecules will form a continuous thin layer on the inner wall of the pipe. When the liquid rises, the capillary phenomenon makes the liquid in a static equilibrium state, and this equilibrium state makes the liquid unable to drip naturally, minimizing the liquid dripping phenomenon in the dripping pipe 4. Under the action of atmospheric pressure, the liquid sauce in each branch pipe will remain in the branch pipe, avoiding the phenomenon of leakage and dripping.

[0026] It also includes a bracket 6. The confluence pipe 1 is arranged on the bracket 6. In this embodiment, the confluence pipe 1 is symmetrically arranged on the bracket 6. In this embodiment, two confluence pipes 1 are symmetrically arranged on the bracket 6. Each confluence pipe 1 is connected to a plurality of branch pipes. In this embodiment, each confluence pipe 1 is connected to 6 branch pipes, and the specific number of branch pipes can be set according to actual situations.

[0027] There is a seasoning chamber in the bracket 6, and a seasoning mechanism for spraying solid seasonings is installed in the seasoning chamber. This seasoning mechanism refers to the prior art and will not be described in detail here. There is a seasoning outlet at the bottom of the seasoning chamber. The cross-section of the bracket 6 is V-shaped, so that the solid seasonings in the seasoning chamber converge at the seasoning outlet at the bottom, which is convenient for sprinkling solid seasonings on the skewers.

[0028] The shunt pipe 3 is V-shaped with the opening facing inwards, which matches the shape of the bracket 6, and the bracket 6 has a better supporting effect on the shunt pipe 3.

[0029] The opening position of the dripping pipe 4 matches the position of the seasoning outlet, so that the opening position of the dripping pipe 4 and the position of the seasoning outlet are on the same side, which is convenient for synchronously spraying solid seasonings and liquid sauces, and at the same time, the spraying positions are set in the same direction, which is convenient for simultaneously cleaning the liquid sauce seasoning outlet and the solid seasoning outlet.

[0030] There is also a baffle 5 on the bracket 6 for controlling the distance between the dripping pipe 4 and the bracket 6. The baffle 5 is U-shaped, and the baffle 5 is specifically fixed on the bracket 6 by bolts. By controlling the distance between the dripping pipe 4 and the bracket 6 through the baffle 5, the cleaning dead angle of the bracket 6 is minimized as much as possible, which is convenient for cleaning the bracket 6 and the dripping pipe 4.

[0031] In this embodiment, "automatically" means setting the duration and specific amount of seasoning sprinkling according to different seasonings and specific skewers. The specific control device can be implemented with reference to the prior art and will not be described in detail.

[0032] The specific implementation process is as follows:

[0033] The sauce pump pressurizes and conveys the liquid sauce to the confluence pipe 1, and then the liquid sauce is discharged from the confluence pipe 1 and the branch pipes; the dripping time and amount of the liquid sauce are set according to the actual skewers; after the dripping is completed, the solenoid valve is controlled to disconnect the check pipe 2 from the confluence pipe 1 to ensure no waste and no messy dripping causing cleaning problems; to avoid the phenomenon of empty pipes caused by liquid backflow, when spraying again, oil, sauce, water, etc. can be dripped in time to meet the requirements of timely and accurate dripping; at the same time, when the diameter of the dripping pipe 4 is small, when the high-viscosity liquid flows in the thin pipe, the internal friction force and the friction force with the pipe wall are both large, and the flow becomes more difficult, avoiding the phenomenon of empty pipes caused by the natural dripping of the liquid sauce due to gravity when the liquid sauce stops dripping. When spraying again, oil, sauce, water, etc. can be dripped in time to meet the requirements of timely and accurate dripping.

[0034] This solution uses the dripping method to avoid the risk of deflagration caused by the atomization of flammable liquid sauce spraying and will not cause deflagration accidents; using the dripping method to avoid the risk of deflagration caused by the atomization of flammable liquid sauce spraying and will not cause deflagration accidents.

[0035] Embodiment 2:

[0036] The difference between this embodiment and Embodiment 1 is that the check member includes a steel ball. As shown in the appendix Figure 3 A check section is connected in series on the check pipe 2. The check section is located above the confluence pipe 1 and the flow direction of the liquid slurry inside it is upward. The check section is in an inverted conical shape. The steel ball is located in the conical section of the check pipe 2. In this embodiment, the check pipe 2 and the confluence pipe 1 are connected through a conical valve block, and the steel ball is located inside this valve block. The density of the steel ball is greater than the density of the liquid sauce. In this way, when the dripping of the liquid sauce stops, the steel ball naturally falls to block the check section, disconnecting the connection between the confluence pipe 1 and the shunt pipe 3, preventing the liquid in the check pipe 2 from flowing back and avoiding the phenomenon of empty pipes when the dripping of the liquid sauce stops.

[0037] In this solution, a steel ball or a solenoid valve can also be separately set on the check pipe 2 for check, or these two structures can be used simultaneously in different check pipes 2 to avoid the occurrence of check phenomena.
