Abstract
Description
Technical Field
[0001] This utility model relates to a slush bucket, specifically a slush bucket with a plastic inner liner. Background Technology
[0002] Most existing slush buckets consist of inner and outer shells. The inner shell is often made of copper, which is expensive. The outer wall of the inner shell is machined with spiral channels for refrigerant flow. The outer edge of the spiral channels needs to be welded to the inner wall of the outer shell. However, welding the outer edge of the spiral channels is very difficult and prone to localized incomplete welding. This can easily cause air leakage between adjacent channels. Once air leakage occurs between channels, the cooling effect on the local surface of the slush bucket will be greatly reduced, affecting the overall quality. Therefore, designing a slush bucket with a plastic inner liner is particularly important to solve the above problems. Summary of the Invention
[0003] To solve the above problems, this utility model designs a slush bucket with a plastic inner liner structure. The plastic inner cylinder is directly tightened onto the inner wall of the outer shell through a fitting, eliminating the need to weld the outer edge of the spiral refrigerant channel. This greatly simplifies the processing, improves processing efficiency, and replaces the traditional copper spiral channel, thus reducing costs.
[0004] To solve the above-mentioned technical problems, this utility model provides a slush bucket with a plastic inner liner structure. The slush bucket includes an outer shell and a plastic inner liner structure disposed within the outer shell. The plastic inner liner structure is composed of a plastic inner cylinder and an inner shell. The front and rear ends of the inner shell are welded and fixed to the inner wall of the outer shell. The plastic inner cylinder is fitted onto the outer wall of the inner shell. A spiral refrigerant channel is provided on the outer wall of the plastic inner cylinder. The spiral outer edge of the refrigerant channel is tightly attached to the inner wall of the outer shell. Two adjacent refrigerant channels prevent cross-contamination through the fit between the spiral outer edge and the inner wall of the outer shell. The refrigerant channel is also connected to a refrigerant inlet pipe and a refrigerant outlet pipe. One end of the refrigerant inlet pipe and the refrigerant outlet pipe respectively passes through the inner shell and connects to the inner wall of the plastic inner cylinder.
[0005] Further: The refrigerant inlet pipe is connected to the inner wall at the rear end of the plastic inner cylinder and communicates with one end of the spiral refrigerant flow channel; the refrigerant outlet pipe is connected to the inner wall at the front end of the plastic inner cylinder and communicates with the other end of the spiral refrigerant flow channel; the connection between the refrigerant inlet pipe and the plastic inner cylinder is located at the top of the plastic inner cylinder; and the connection between the refrigerant outlet pipe and the plastic inner cylinder is located on the inner wall at the upper end of the plastic inner cylinder.
[0006] Furthermore: the inner shell is composed of a cylindrical body and annular protrusions at the front and rear ends of the body. The annular protrusions at the front and rear ends of the body are fixed to the inner wall of the outer shell by welding. The body has through holes that facilitate the insertion of the refrigerant inlet pipe and the refrigerant outlet pipe. The plastic inner cylinder is fitted onto the body between the annular protrusions at the front and rear ends, and the length between the annular protrusions at the front and rear ends matches the length of the plastic inner cylinder.
[0007] Furthermore, the rear end of the outer shell is provided with an annular positioning and fixing plate integrated therewith. Five U-shaped grooves for installation and fixing are opened around the annular positioning and fixing plate, and two semi-circular positioning grooves are also opened on the outer wall of the annular positioning and fixing plate.
[0008] With the above structure, this utility model can directly tighten the plastic inner cylinder onto the inner wall of the outer shell through a through-fit, eliminating the need to weld the outer edge of the spiral refrigerant flow channel, which greatly simplifies the processing, improves the processing efficiency, and can also effectively prevent cross-ventilation between adjacent flow channels due to poor welding seal; in addition, this design replaces the traditional copper spiral flow channel, which helps to reduce costs.

[0013] like Figure 1 and Figure 2The slush bucket shown includes an outer shell and a plastic inner liner structure disposed within the outer shell. The plastic inner liner structure is composed of a plastic inner cylinder 2 and an inner shell 3. The front and rear ends of the inner shell are welded and fixed to the inner wall of the outer shell. The plastic inner cylinder is fitted onto the outer wall of the inner shell. A spiral refrigerant channel 2-1 is provided on the outer wall of the plastic inner cylinder. The spiral outer edge of the refrigerant channel of the plastic inner cylinder is tightly attached to the inner wall of the outer shell. Two adjacent refrigerant channels prevent air leakage through the fit between the spiral outer edge and the inner wall of the outer shell. The refrigerant channel is also connected to a refrigerant inlet pipe 4 and a refrigerant outlet pipe 5. One end of the refrigerant inlet pipe and the refrigerant outlet pipe respectively passes through the inner shell and is connected to the inner wall of the plastic inner cylinder. This invention directly tightens the plastic inner cylinder onto the inner wall of the outer shell through a flexible fit, eliminating the need to weld the outer edge of the spiral refrigerant flow channel. This greatly simplifies processing, improves processing efficiency, and effectively prevents cross-contamination between adjacent flow channels due to incomplete welding. Furthermore, this design replaces the traditional copper spiral flow channel, thus reducing costs.
[0014] like Figure 2 and Figure 3 The refrigerant inlet pipe is connected to the inner wall at the rear end of the plastic inner cylinder and is connected to one end of the spiral refrigerant flow channel. The refrigerant outlet pipe is connected to the inner wall at the front end of the plastic inner cylinder and is connected to the other end of the spiral refrigerant flow channel. The connection between the refrigerant inlet pipe and the plastic inner cylinder is located at the top of the plastic inner cylinder, and the connection between the refrigerant outlet pipe and the plastic inner cylinder is located on the inner wall at the upper end of the plastic inner cylinder.
[0015] like Figure 2 and Figure 3 The inner shell shown is composed of a cylindrical body 3-1 and annular protrusions 3-2 at the front and rear ends of the body. The annular protrusions at the front and rear ends of the body are fixed to the inner wall of the outer shell by welding. The body has through holes that facilitate the insertion of the refrigerant inlet pipe and the refrigerant outlet pipe. The plastic inner cylinder is fitted onto the body between the annular protrusions at the front and rear ends. The length between the annular protrusions at the front and rear ends matches the length of the plastic inner cylinder.
[0016] like Figure 1 The rear end of the outer casing is provided with an annular positioning and fixing plate 6 integrated therewith. Five U-shaped grooves 7 for installation and fixing are formed around the annular positioning and fixing plate, and two semi-circular positioning grooves 8 are also formed on the outer wall of the annular positioning and fixing plate. This design facilitates installation.
