Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and in particular to an evaporating cylinder and an ice maker. Background Art

[0002] The emergence of ice cubes allows people to enjoy cool drinks in the hot summer. Ice cubes are produced by ice making machines. The main working principle of common ice making machines is mainly based on refrigeration technology, which lowers the temperature of water by circulating refrigerant to make it freeze. Specifically, in the refrigeration system, the refrigerant circulates in the side wall pipes of the evaporator tube, and water is introduced into the evaporator tube (usually called an evaporator) through a water pump. There is a screw mechanism in the evaporator tube to make the water move up along the evaporator tube. Because the temperature in the evaporator tube is low (usually around minus 20 degrees Celsius), the water will quickly freeze into ice, and the screw mechanism will squeeze the ice out of the evaporator tube. This process will be repeated continuously to achieve continuous ice making. However, when the ice is continuously discharged, the ice cubes often rotate together with the screw mechanism and cannot rise and squeeze out, which eventually causes the evaporator tube to be blocked by ice cubes. Therefore, it is necessary to optimize and improve the existing technology. Utility Model Content

[0003] The utility model provides an evaporating cylinder and an ice maker, which solve the problem in the related art that when continuously discharging ice, ice cubes often rotate together with a screw mechanism and cannot rise and be squeezed out, resulting in the evaporating cylinder being blocked by ice cubes.

[0004] The technical solution of the utility model is as follows:

[0005] An evaporation cylinder is used to freeze the water flowing into it into ice and then discharge it. The evaporation cylinder comprises a cylinder body, wherein the cylinder body has an ice-forming channel, wherein the ice-forming channel has an inlet and an outlet, wherein the inner wall of the ice-forming channel has ridges or grooves, wherein the ridges and grooves are arranged in multiple circles.

[0006] As a further technical solution, the cylinder has an ice-making space, the outlet is located at one end of the cylinder, and the inlet is arranged on the side wall of the cylinder, located at an end away from the inlet of the cylinder.

[0007] As a further technical solution, the cylinder body further comprises a cooling cavity, the cooling cavity is located outside the ice-forming channel, and the cooling cavity comprises a cooling inlet and a cooling outlet.

[0008] As a further technical solution, the cooling cavity is a spiral cavity with a rectangular cross-section.

[0009] As a further technical solution, the cooling cavity is a spiral cavity with a semicircular cross-section.

[0010] As a further technical solution, the convex ridge is in a straight line, a spiral or an oblique line shape, and the groove is in a straight line, a spiral or an oblique line shape.

[0011] As a further technical solution, the ice forming channel further comprises a first flange seat connecting hole and a second flange seat connecting hole, and the first flange seat connecting hole and the second flange seat connecting hole are respectively located at two ends of the ice forming channel.

[0012] As a further technical solution, the first flange seat connection holes are arranged in a plurality of circles, and the second flange seat connection holes are arranged in a plurality of circles.

[0013] As a further technical solution, a screw conveyor is also included, and the screw conveyor is rotatably arranged in the ice forming channel.

[0014] An ice making machine includes an evaporating cylinder.

[0015] The working principle and beneficial effects of the utility model are that the cylinder has an ice-forming channel, water flows in from the entrance of the ice-forming channel, and is condensed into ice in the ice-forming channel under the drive of the spiral conveyor. Taking into account that during the condensation process in the ice-forming channel, the ice may rotate synchronously with the spiral conveyor and cannot be discharged, the present scheme provides a plurality of circumferentially arranged ridges or grooves on the inner wall of the ice-forming channel. The frozen ice can be discharged from the ice-forming channel under the guiding action of the ridges or grooves and the conveying action of the spiral conveyor, thereby avoiding the problem that the device cannot produce ice normally due to the inability of the spiral conveyor to discharge the ice normally due to water condensation and being blocked in the ice-forming channel, and at the same time avoiding damage to the device caused by ice blockage.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1~Figure 4 As shown, this embodiment proposes an evaporation cylinder for freezing the incoming water into ice and then discharging it, including a cylinder body 1 having an ice-forming channel 101 with an inlet 102 and an outlet 103, and the inner wall of the ice-forming channel 101 has ridges 104 or grooves 105, and the ridges 104 and the grooves 105 are both arranged in multiple circles.

[0024] In this embodiment, a cylinder 1 is provided, and the cylinder 1 has an ice-forming channel 101. Water flows in from the inlet 102 of the ice-forming channel 101, and is condensed into ice in the ice-forming channel 101 driven by the screw conveyor 2. Taking into account that during the condensation process in the ice-forming channel 101, the ice may rotate synchronously with the screw conveyor and cannot be discharged. In this scheme, a plurality of circumferentially arranged ridges 104 or grooves 105 are provided on the inner wall of the ice-forming channel 101. The frozen ice can be discharged from the ice-forming channel 101 under the guiding action of the ridges 104 or grooves 105 and the conveying action of the screw conveyor 2, thereby avoiding the problem that the device cannot produce ice normally due to the inability of the screw conveyor 2 to discharge the ice normally due to water condensation and being blocked in the ice-forming channel 101, and at the same time avoiding damage to the device caused by ice blockage.

[0025] Furthermore, the cylinder 1 has an ice-making space 106 , the outlet 103 is located at one end of the cylinder 1 , and the inlet 102 is arranged on the side wall of the cylinder 1 , at an end away from the inlet 102 of the cylinder 1 .

[0026] In this embodiment, the ice-making space 106 is provided with an inlet 102 on the side wall of the cylinder 1. The inlet 102 is arranged on the side wall, and the cooling liquid flows into the ice-making space 106 more smoothly and is not easy to flow back. The outlet 103 of the ice-making space 106 is arranged at one end of the cylinder 1, and the cooling liquid flows slowly and smoothly inside the cylinder 1, so that the cooling liquid can be used more efficiently, thereby improving the ice-making efficiency of the ice maker.

[0027] Furthermore, the cylinder 1 also has a cooling cavity 107 , which is located outside the ice forming channel 101 , and has a cooling inlet 108 and a cooling outlet 109 .

[0028] In this embodiment, a cooling chamber 107 is arranged outside the ice-forming channel 101, and the cooling chamber 107 has a cooling inlet 108 and a cooling outlet 109. The coolant flows in from the cooling inlet 108 and flows out from the cooling outlet 109. During the flow, the low temperature of the coolant is used to cool the water in the ice-forming channel 101 to make it freeze. The coolant remains in a flowing state, so that the coolant always maintains a low temperature, maintains a high cooling efficiency in the ice-making space 106, and keeps the cooling function and effect of the entire device in an efficient and stable state.

[0029] Furthermore, the cooling cavity 107 is a spiral cavity with a rectangular cross section.

[0030] In this embodiment, the cooling chamber 107 can be configured as a spiral chamber with a rectangular cross section, and a spiral chamber with a rectangular cross section can achieve a uniform cooling effect. By guiding the coolant circulation to various parts of the device, it can be ensured that each part can be sufficiently cooled to avoid hot spot concentration and uneven temperature. Compared with a one-way cooling system, the spiral chamber liquid pipeline with a rectangular cross section can be arranged more compactly in the device. This can save space, make the overall size of the device smaller, and provide better cooling efficiency when the space of the device is limited.

[0031] Furthermore, the cooling cavity 107 is a spiral cavity with a semicircular cross section.

[0032] In this embodiment, the cooling chamber 107 can also be set as a spiral chamber with a semicircular cross section. The spiral chamber with a semicircular cross section can effectively reduce the flow rate and pressure change of the liquid in the pipeline by increasing the length of the pipeline. This can reduce the pressure drop of the liquid, reduce the energy consumption of the system, and help improve the flow stability of the coolant. The design of the spiral coolant pipeline can provide a uniform flow and cooling effect, reducing the possibility of stagnation or dead corners of the coolant in certain parts. This helps to prevent the generation of bubbles and dirt, improve the stability and reliability of the coolant refrigeration of the water flow in the ice making space 106, and can also achieve a reduction in the flow of the coolant while ensuring sufficient cooling efficiency, improve the utilization efficiency of the materials in the overall device and achieve energy-saving effects.

[0033] Furthermore, the ridge 104 is in a straight line, a spiral or an oblique line shape, and the groove 105 is in a straight line, a spiral or an oblique line shape.

[0034] In this embodiment, the ridges 104 or grooves 105 arranged on the inner wall of the ice-forming channel 101 are straight, spiral or oblique. The ridges 104 or grooves 105 arranged on the inner wall of the ice-forming channel 101 are straight, which can make the formed ice slide and fall quickly through the straight ridges 104 or grooves 105 to prevent the occurrence of blockage. The ridges 104 or grooves 105 arranged on the inner wall of the ice-forming channel 101 are spiral or oblique. The formed ice rotates and slides down along the ridges 104 or grooves 105 in the ice-forming channel 101, which can effectively avoid the ice from condensing and sticking to the inner wall of the ice-forming channel 101, thus preventing the occurrence of blockage.

[0035] Furthermore, the ice forming channel 101 also has a first flange seat connecting hole 110 and a second flange seat connecting hole 111 , and the first flange seat connecting hole 110 and the second flange seat connecting hole 111 are respectively located at two ends of the ice forming channel 101 .

[0036] In this embodiment, the cylinder 1 is vertically arranged on the ice maker. Taking into account the instability of the cylinder 1 during the ice making process, the cylinder 1 is connected to the ice maker through a flange, and the ice forming channel 101 is provided with a flange seat connecting hole for fixing the flange connecting seat so that the fixing flange can be tightly fixed on the cylinder 1, so that the cylinder 1 can be more stably fixed on the ice maker.

[0037] Furthermore, the first flange seat connection holes 110 are arranged in a plurality of circles, and the second flange seat connection holes 111 are arranged in a plurality of circles.

[0038] In this embodiment, a plurality of flange seat connection holes are arranged circumferentially, so that the flange seat can be more conveniently and stably arranged on the cylinder body 1.

[0039] Furthermore, the invention also includes a spiral conveying member 2 rotatably disposed in the ice forming channel 101 .

[0040] In this embodiment, a spiral conveyor 2 is rotatably arranged in the ice-forming channel 101. The spiral conveyor 2 conveys water from the inlet 102 to the outlet 103 through the rotation of the spiral blade. In the process, the water is cooled into ice by contacting with the cooling chamber 107, and the formed ice is smoothly conveyed from one end to the other end of the ice-forming channel 101. The spiral conveyor 2 can bear enough resistance to effectively convey the produced ice, and the conveying speed can be further increased, including an evaporation cylinder.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
