Technical Field

[0001] The utility model relates to the technical field of ice making, and particularly relates to a flooded ice making evaporator and an ice maker. Background Art

[0002] With the popularity of cold drinks, as a device for making ice cubes, ice makers are widely used. When making ice, the ice maker makes the refrigerant (i.e., the refrigerant) exchange heat with room temperature water, so that the room temperature water condenses into ice cubes. The ice cubes formed after condensation can be added to different drinks to meet the user's demand for cold drinks. At present, when making ice, the following problems exist in the ice maker: the refrigerant circulates relatively fast, and the effective contact time with the cylinder body is less, which affects the heat exchange efficiency and the ice making efficiency. There are a large number of bubbles in the made ice cubes, showing a non-transparent state, and the visual effect is poor. The made ice cubes are easy to stick and accumulate to block the ice outlet.

In the accompanying drawings of the embodiments of the present utility model, a coordinate system XYZ is set, where the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the upper, and the negative direction of the Z-axis represents the lower

[0026] The embodiment of the present utility model provides a flooded ice-making evaporator, in combination with Figures 1-6 As shown, a flooded ice-making evaporator includes a base 1, an inner cylinder 2, and an outer cylinder 3 disposed around the inner cylinder 2. An inner flow channel 33 for refrigerant circulation is formed between the inner cylinder 2 and the outer cylinder 3. The inner flow channel 33 includes a plurality of flow zones distributed from top to bottom. The outer cylinder 3 is provided with an input pipe 31 and an output pipe 32 for refrigerant circulation. Both the input pipe 31 and the output pipe 32 are connected to the inner flow channel 33. The refrigerant enters the inner flow channel 33 through the input pipe 31, flows through each flow zone from top to bottom, and then flows out through the output pipe 32

[0027] As shown Figure 1 in the figure, the cylinder body includes a base 1 and an inner cylinder 2. The base 1 is welded to the inner cylinder 2 or integrally formed. An outer cylinder 3 is disposed around the inner cylinder 2, and an inner flow channel 33 is formed between the outer cylinder 3 and the inner cylinder 2. The base 1 is used to fixedly install the evaporator in the ice maker, and the inner cylinder 2 and the outer cylinder 3 cooperate to make ice. A water inlet pipe 21 is provided on the inner cylinder 2. The position of the input pipe 31 in the vertical direction is higher than that of the output pipe 32, so as to facilitate the smoother flow of the refrigerant under the action of gravity. The position of the output pipe 32 in the vertical direction is higher than that of the water inlet pipe 21.

[0028] In this embodiment, the input pipe 31 is a copper pipe, the output pipe 32 is a capillary copper pipe, and the water inlet pipe 21 is a silicone tube. Both the input pipe 31 and the output pipe 32 are welded to the outer cylinder 3. The inner cylinder 2 and the base 1 are laser welded, and the inner cylinder 2 and the outer cylinder 3 are laser welded. The inner cylinder 2 is integrally formed, reducing the processing procedures, improving the manufacturing efficiency, and reducing the cost.

[0029] In the full liquid ice making evaporator of the present utility model, by providing a plurality of flow zones distributed from top to bottom, the refrigerant passes through different flow zones, and the refrigerant passes through each flow zone from top to bottom, thereby prolonging the time for the refrigerant to pass through the inner flow channel 33, making the inner cylinder 2 receive cold for a longer time, having a better ice making effect, and increasing the heat exchange efficiency and ice making efficiency.

[0030] The inner flow channel 33 includes a plurality of partition rings distributed up and down. The partition rings are used to separate different flow zones. Flow ports for communicating the flow zones are provided on the partition rings, and adjacent two flow ports are staggered in the up and down directions.

[0031] As Figure 4 and 5 shown in the figure, in this embodiment, the partition rings divide the inner flow channel 33 into four flow zones. The refrigerant passes through each layer of partition ring from top to bottom through the flow ports, thereby prolonging the time for the refrigerant to pass through the inner flow channel 33, and thus making the inner cylinder 2 receive cold for a longer time and having a better ice making effect.

[0032] As Figure 4 and 5As shown, in this embodiment, there are three separating rings, which are the first separating ring 331, the second separating ring 332, and the third separating ring 333 from top to bottom. There are three flow ports, which are the first flow port 334, the second flow port 335, and the third flow port 336 from top to bottom. The first separating ring 331 and the upper end wall of the outer cylinder 3 cooperate to form a first flow area. The first separating ring 331 and the second separating ring 332 cooperate to form a second flow area. The second separating ring 332 and the third separating ring 333 cooperate to form a third flow area. The third separating ring 333 and the lower end wall of the outer cylinder 3 cooperate to form a fourth flow area.

[0033] The refrigerant flows through the first flow area, the second flow area, the third flow area, and the fourth flow area in sequence from top to bottom, thereby prolonging the residence time of the refrigerant in the inner flow channel 33 and making the ice-making effect of the inner cylinder 2 better.

[0034] The projections of the first flow port 334 and the third flow port 336 on the horizontal plane coincide, and the projections of the first flow port 334 and the second flow port 335 on the horizontal plane are distributed at both ends of the outer cylinder 3.

[0035] As Figure 4 and 5 shown, setting the positions of the flow ports in this way can allow the refrigerant to fully flow through each separating ring, thereby further prolonging the residence time of the refrigerant in the inner flow channel 33 and making the ice-making effect of the inner cylinder 2 better.

[0036] The flooded ice-making evaporator further includes an ice pushing member 4. The ice pushing member 4 is accommodated in the cylinder body. An opening 42 is provided at the upper end of the ice pushing member 4. An exhaust cavity 45 is provided inside the ice pushing member 4. An exhaust hole 44 communicating with the cylinder body is provided on the side wall of the ice pushing member 4. The exhaust cavity 45 communicates with the opening 42 and the exhaust hole 44 to discharge the gas generated during the ice-making process in the cylinder body.

[0037] The flooded ice-making evaporator further includes a speed reducer (not shown). The ice pushing member 4 includes a rotating shaft portion 41. A square hole 46 is provided at the lower end of the rotating shaft portion 41. The square shaft of the speed reducer is connected to the square hole 46, and the speed reducer drives the ice pushing member 4 to rotate.

[0038] As Figure 2 and 3As shown, in this embodiment, the ice pushing member 4 is received in the inner cylinder 2, and the exhaust hole 44 communicates with the inner cylinder 2 to discharge the gas generated in the inner cylinder 2 during the ice making process. The exhaust cavity 45 is coaxially arranged with the ice pushing member 4. The exhaust cavity 45 is provided in the rotating shaft portion 41, which does not occupy extra space and does not affect the ice making of the inner cylinder 2, and the structure is simple and ingenious. The ice making cavity 23 in the inner cylinder 2 communicates with the exhaust cavity 45 through the exhaust hole 44. At the same time, the exhaust hole 44 rotates with the rotating shaft portion 41, and can discharge the gas at various angles in the inner cylinder 2.

[0039] The air bubbles in the ice cubes are caused by the change in the solubility of air during the phase change of water. When water changes from a liquid state to a solid state, the gas dissolved in the air separates from the water due to the sudden change in solubility, forming air bubbles. These air bubbles are trapped in the ice cubes, resulting in air bubbles in the ice cubes and thus presenting a relatively turbid appearance. By providing the exhaust cavity 45 in the ice pushing member 4, the present utility model can discharge the gas generated in the inner cylinder 2 during the ice making process through the exhaust cavity 45, so that the ice cubes produced have no air bubbles and can present a transparent state, giving users a better visual experience, and the structure is simple and ingenious.

[0040] The full liquid type ice making evaporator further includes a connecting member 6 connected to the upper end of the ice pushing member 4. The connecting member 6 penetrates up and down and communicates with the opening 42.

[0041] As Figure 1 and 2 shown, in this embodiment, a part of the connecting member 6 is in a cylindrical structure and is connected to the upper end of the rotating shaft portion 41 through the cylindrical structure. The gas inside the exhaust cavity 45 is discharged through the upper part of the connecting member 6.

[0042] The connecting member 6 is provided with an ice breaking portion 61. The connecting member 6 is fixedly connected to the ice pushing member 4 and rotates synchronously with the ice pushing member 4. The ice breaking portion 61 is used for breaking the ice cubes and at the same time stirring the ice cubes to prevent adhesion and accumulation.

[0043] As Figure 1 and 2 shown, in this embodiment, the ice breaking portion 61 is L-shaped. The ice cubes are extruded from the ice outlet 51 of the ice outlet mold 5 and are broken when they encounter the rotating ice breaking portion 61 above, thereby preventing the produced ice cubes from being too large. At the same time, during the rotation of the ice breaking portion 61, the ice cubes will be stirred, thereby avoiding adhesion and accumulation of the ice cubes at the ice outlet 51.

[0044] The full liquid type ice making evaporator further includes an ice outlet mold 5. The ice outlet mold 5 is detachably connected to the upper end of the cylinder body. A spiral scraper 43 is provided on the ice pushing member 4. The ice pushing member 4 is driven by an external force to rotate, and the spiral scraper 43 pushes the ice cubes in the cylinder body to be extruded through the ice outlet mold 5.

[0045] As Figure 1As shown, the ice discharging mold 5 is connected to the upper end of the inner cylinder 2 by threads, and the spiral scraper 43 pushes the ice cubes in the inner cylinder 2 to be extruded through the ice discharging mold 5. A plurality of ice discharging ports 51 are provided on the ice discharging mold 5, and the ice breaking member is arranged above the ice discharging ports 51. In this embodiment, there are six ice discharging ports 51, and the shape of the ice discharging ports 51 determines the shape of the ice cubes produced.

[0046] The ice discharging mold 5 and the inner cylinder 2 are connected by threads. The flooded ice making evaporator further includes a bushing 7. The upper end of the rotating shaft portion 41 passes through the ice discharging mold 5 and is connected to the connecting member 6. The bushing 7 is arranged between the rotating shaft portion 41 and the ice discharging mold 5. At the same time, the bushing 7 is arranged around the upper end of the rotating shaft portion 41 to make the rotation of the rotating shaft portion 41 smoother.

[0047] The spiral scraper 43 is arranged on the side wall of the rotating shaft portion 41, and the ice pushing member 4 is integrally formed. The reduction gear drives the rotating shaft to rotate, and the spiral scraper 43 spirally pushes the ice cubes in the inner cylinder 2 upward and extrudes them from the ice discharging ports 51.

[0048] A spiral track 22 adapted to the spiral scraper 43 is recessed on the inner wall of the cylinder body, and the spiral scraper 43 is slidably connected to the spiral track 22. Thus, the rotation of the spiral scraper 43 is smoother and the structure is more stable. As Figure 2 and 3 shown, the spiral track 22 is recessed on the inner wall of the inner cylinder 2.

[0049] Another embodiment of the present invention provides an ice maker, including the flooded ice making evaporator as described above.

[0050] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
