Description

Technical Field

[0001] This utility model belongs to the field of ice maker technology, and in particular to an ice extrusion device. Background Technology

[0002] An ice maker is a refrigeration machine that produces ice by cooling water through an evaporator with a refrigerant in a refrigeration system. It uses a refrigeration system with water as the carrier and produces ice by passing it through a device when powered on. Depending on the principle of the evaporator and the production method, the shape of the ice produced will also be different. Ice makers are generally classified according to the shape of the ice, such as granular ice makers, flake ice makers, plate ice makers, tube ice makers, shell ice makers, etc.

[0003] Current ice makers typically use a rotating screw to expel ice cubes from the outlet. The extrusion pressure is increased by chamfering the bottom of the outlet to shape the ice cubes. However, this structure cannot guarantee the ice-making effect. The increased extrusion pressure from the chamfered bottom of the outlet alone cannot guarantee the hardness of the ice cubes, thus affecting the quality of the ice. Utility Model Content

[0004] In view of this, the present invention provides an ice-making extrusion device that can increase the hardness of ice blocks to meet industrial needs.

[0005] An ice-making extrusion device includes a drive unit and an ice-making evaporator mounted on the drive unit for transporting ice blocks. The drive unit includes a drive body and a spiral shaft mounted on the drive body. The ice-making evaporator includes an ice-making tube fixedly connected to the drive body and sleeved on the spiral shaft, a water inlet at one end of the ice-making tube, and an ice outlet assembly at the end of the ice-making tube opposite to the water inlet. The ice-making tube includes an ice-making tube body and an ice-extrusion channel disposed within the ice-making tube. The ice outlet assembly includes an ice outlet seat inserted into the end of the ice-making tube opposite to the water inlet, and a plurality of ice outlet groove-shaped through holes disposed on the sidewall of the ice outlet seat. Each ice outlet groove-shaped through hole includes an ice-extrusion section and an inlet section disposed at the end of the ice-extrusion section facing the water inlet. Both the ice-squeezing section and the inlet section are conical, with the large-diameter ends of both the inlet section and the ice-squeezing section facing the ice-squeezing channel, so that the ice in the ice-squeezing channel can flow into the ice outlet trough-shaped through hole to form ice blocks.

[0006] Furthermore, the ice-making tube also includes multiple anti-slip grooves disposed within the ice-extrusion channel, the extension direction of which is consistent with the extension direction of the ice-extrusion channel.

[0007] Furthermore, multiple anti-slip grooves are arranged in a circumferential array within the ice-squeezing channel.

[0008] Furthermore, the length of the ice-squeezing section is greater than the length of the inlet section.

[0009] Furthermore, the ice-making evaporator includes a refrigeration unit disposed outside the ice-making tube. The refrigeration unit includes a refrigeration sleeve fixedly connected to the outside of the ice-making tube, a refrigeration inlet disposed on the refrigeration sleeve, and a refrigeration outlet disposed outside the refrigeration sleeve.

[0010] Furthermore, the ice-making evaporator includes a refrigeration unit disposed outside the ice-making tube. The refrigeration unit includes a refrigeration sleeve fixedly connected to the outside of the ice-making tube, a refrigeration inlet disposed on the refrigeration sleeve, and a refrigeration outlet disposed outside the refrigeration sleeve.

[0011] Furthermore, the ice-making evaporator also includes a protective cover disposed at the end of the ice-making tube facing the ice outlet assembly.

[0012] Furthermore, each of the ice outlet groove-shaped through holes also includes a flat section disposed at the end of the ice extrusion section opposite to the inlet section, the outer contour of the flat section being rectangular.

[0013] Compared with the prior art, the ice-making extrusion device provided by this utility model extrudes ice blocks transmitted by the driving device through the ice-making evaporator, forming the ice blocks into shapes. The ice-making evaporator includes an ice-making tube fixedly connected to the driving body and sleeved on the spiral shaft, a water inlet at one end of the ice-making tube, and an ice outlet assembly at the end of the ice-making tube opposite to the water inlet. The water inlet guides the ice blocks into the extrusion channel of the ice-making tube. The driving body in the driving device drives the spiral shaft to rotate, sequentially transmitting the ice blocks to the ice outlet assembly. The ice outlet assembly has ice outlet groove-shaped through holes on the side wall of the ice outlet seat. Each ice outlet groove-shaped through hole includes an ice extrusion section and an inlet section at the end of the ice extrusion section facing the water inlet. Both the inlet section and the ice-extrusion section are conical, with their large-diameter ends facing the ice-extrusion channel. As loose ice enters and is transported within these sections, it is gradually compressed, increasing the compressive force to harden the ice and form it into a solid block. This demonstrates that the ice-making extrusion device increases the hardness of the ice, making it more compact. Attached Figure Description

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figures 1 to 3 The diagram shown is a structural schematic of the ice-making extrusion device provided by this utility model. The ice-making extrusion device includes a driving device 10, an ice-making evaporator 20 disposed on the driving device 10 and used for conveying ice blocks (not shown), and other functional modules, such as assembly components, etc., which should be known to those skilled in the art and will not be described in detail here.

[0019] The driving device 10 includes a driving body 11 and a spiral shaft 12 disposed on the driving body 11.

[0020] The driving body 11 is a drive motor, which is an electrical device that converts electrical energy into mechanical energy. The driving body 11 drives the spiral shaft 12 to rotate, and the spiral shaft 12 drives the ice block to move. The driving body 11 is a prior art and will not be described in detail here.

[0021] The driving body 11 is connected to the spiral shaft 12. The driving body 11 can drive the spiral shaft 12 to rotate. When the driving body 11 drives the spiral shaft 12 to rotate during the rotation of the spiral shaft 12, the spiral shaft 12 can transport the ice block to the ice outlet slot-type through hole 232 in the ice outlet assembly 23 to realize the formation of the ice block. The spiral shaft 12 is a screw structure that can convert rotational motion into linear motion and torque into thrust. The connection structure between the spiral shaft 12 and the driving body 11, as well as the spiral shaft 12 itself, are all existing technologies and will not be described in detail here.

[0022] The ice-making evaporator 20 includes an ice-making tube 21 fixedly connected to the drive body 11 and sleeved on the spiral shaft 12, a water inlet 22 disposed at one end of the ice-making tube 21, an ice outlet assembly 23 disposed at the end of the ice-making tube 21 facing away from the water inlet 22, a refrigeration unit 24 disposed outside the ice-making tube 21, and a protective cover 25 disposed at the end of the ice-making tube 21 facing the ice outlet assembly 23.

[0023] The ice-making tube 21 includes an ice-making tube body 211, an ice-squeezing channel 212 disposed within the ice-making tube 211, and multiple anti-slip grooves 213 disposed within the ice-squeezing channel 212.

[0024] The ice-making tube body 211 is a hollow tubular structure. One end of the ice-making tube body 211 is fixedly connected to the driving body 11, and the ice-making tube body 211 is sleeved on the spiral shaft 12. The ice-making tube body 211 is a prior art and will not be described in detail here.

[0025] The ice squeezing channel 212 is used to transport water entering through the inlet 22 through the refrigeration unit 24. During the transport process of the water in the ice squeezing channel 212, the water forms loose ice and the loose ice flows to the ice outlet assembly 23. The ice squeezing channel 212 is a prior art and will not be described in detail here.

[0026] The extension direction of the anti-slip grooves 213 is consistent with the extension direction of the ice squeezing channel 212. The anti-slip grooves 213 can guide the ice blocks to one end of the ice outlet component 23 in sequence. Multiple anti-slip grooves 213 are arranged in a circumferential array in the ice squeezing channel 212 to ensure that the ice blocks in the ice squeezing channel 212 flow evenly. The anti-slip grooves 213 are existing technologies and will not be described in detail here.

[0027] The water inlet 22 is used to inject water into the ice-making pipe 21. The water inlet 22 is a prior art and will not be described in detail here.

[0028] The ice outlet assembly 23 includes an ice outlet seat 231 inserted into the end of the ice-making tube 21 facing away from the water inlet 22, a plurality of ice outlet groove-shaped through holes 232 disposed on the side wall of the ice outlet seat 231, and a spiral shaft insertion hole 233 disposed on the ice outlet seat 231.

[0029] Each ice outlet trough-shaped through-hole 232 includes an ice-squeezing section 2321, an inlet section 2322 disposed at one end of the ice-squeezing section 2321 facing the water inlet 22, and a leveling section 2323 disposed at one end of the ice-squeezing section 2321 away from the inlet section 2322. The spiral shaft 12 transports loose ice to the inlet section 2322 and the ice-squeezing section 2321, and in the process of continuously transporting ice, it provides an upward rotational force to the ice blocks in the inlet section 2322 and the ice-squeezing section 2321, through the inlet section 2322, the ice-squeezing section 2321, and the leveling section 2323. The inlet section 2322 and the ice-squeezing section 2321 are both conical, with their large-diameter ends facing the ice-squeezing channel 212. This allows ice in the ice-squeezing channel 212 to flow into the ice-discharge through-hole 232, where it is squeezed into shape during transport by the inlet section 2322 and the ice-squeezing section 2321, ensuring the ice's hardness. Furthermore, the length of the ice-squeezing section 2321 is greater than the length of the inlet section 2322 to increase the squeezing time of the ice within the ice-squeezing section 2321, improving the squeezing effect. The flattening section 2323 has a rectangular outer contour, ensuring a smooth surface for the ice as it passes through, enhancing its appearance.

[0030] The spiral shaft insertion hole 233 is used to insert one end of the spiral shaft 12, thereby restricting the position of one end of the spiral shaft 12 so as to stabilize the spiral shaft 12 during rotation.

[0031] The refrigeration unit 24 includes a refrigeration sleeve 241 fixedly connected to the outside of the ice-making tube 21, a refrigeration inlet 242 disposed on the refrigeration sleeve 241, and a refrigeration outlet 243 disposed on the outside of the refrigeration sleeve 241. The refrigeration inlet 242 and the refrigeration outlet 243 circulate refrigerant between the refrigeration sleeve 241 and the ice-making tube 21 to reduce the temperature inside the ice-making tube 21 and achieve ice formation. The refrigeration sleeve 241, the refrigeration inlet 242, and the refrigeration outlet 243 are all existing technologies and will not be described in detail here.

[0032] The protective cover 25 is disposed at the end of the ice-making tube 21 facing the ice outlet assembly 23 to guide the ice blocks flowing out through the ice outlet assembly 23. The protective cover 25 is a prior art and will not be described in detail here.

[0033] When the ice-making extrusion device makes ice, refrigerant enters and exits through the refrigeration inlet 242 and refrigeration outlet 243 in the refrigeration unit 24, and the refrigeration unit 24 in the ice-making evaporator 20 transmits refrigerant to ensure the temperature inside the ice-making tube 21. Water enters the ice-making tube 21 through the water inlet 22. The ice-making evaporator 20 rotates the spiral shaft 12 upward. During the upward process, the water in the ice-making tube 21 is heated by the refrigerant in the refrigeration unit 24 and forms loose ice. The loose ice in the ice-squeezing channel 212 is transported to the ice outlet assembly 23 by the rotation of the spiral shaft 12. The ice outlet assembly 23 is provided with ice outlet groove-type through holes 232. Each ice outlet groove-type through hole 232 includes an inlet section 2322 and an ice-squeezing section 2321. The inlet section 2322 and the ice-squeezing section 2321 are both conical. The large diameter ends of the inlet section 2322 and the ice-squeezing section 2321 face the ice-squeezing channel 212. When the loose ice enters the inlet section 2322 and the ice-squeezing section 2321, the loose ice is gradually squeezed. By increasing the squeezing pressure, the ice block is hardened and the loose ice is squeezed into an ice block.

[0034] Compared with the prior art, the ice-making extrusion device provided by this utility model extrudes ice blocks transmitted by the driving device 10 through the ice-making evaporator 20, forming the ice blocks into shape. The ice-making evaporator 20 includes an ice-making tube 21 fixedly connected to the driving body 11 and sleeved on the spiral shaft 12, a water inlet 22 disposed at one end of the ice-making tube 21, and an ice outlet assembly 23 disposed at the end of the ice-making tube 21 opposite to the water inlet 22. The water inlet 22 guides the ice blocks into the extrusion channel 212 of the ice-making tube 21, and the driving body 11 in the driving device 10 drives the spiral shaft 12 to rotate, sequentially transmitting the ice blocks to the ice outlet assembly 23. The ice outlet assembly 23 has ice outlet groove-shaped through holes 232 on the side wall of the ice outlet seat 231. Each ice outlet groove-shaped through hole 232 includes an ice extrusion section 2321 and an inlet section 2322 located at the end of the ice extrusion section 2321 facing the water inlet 22. Both the inlet section 2322 and the ice extrusion section 2321 are conical, and the large-diameter ends of the inlet section 2322 and the ice extrusion section 2321 face the ice extrusion channel 212. When loose ice enters the inlet section 2322 and the ice extrusion section 2321, the loose ice is gradually compressed, and the ice block is hardened by increasing the compression force, thus forming an ice block. It can be seen that the ice extrusion device increases the hardness of the ice block, making the ice block more compact.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
