Description

Technical Field

[0001] This utility model relates to the field of shaved ice machine technology, and in particular to an evaporator structure for a shaved ice machine. Background Technology

[0002] Frozen ice machines are a type of ice maker. The ice produced by these machines is finer, below freezing, highly malleable, and easy to handle and stack. The resulting ice is irregularly shaped like snowflakes or thin strips of crushed ice, widely used in the food and beverage industry. Frozen ice machines produce ice by condensing beverages or liquid ingredients through an evaporator structure, rapidly solidifying them into frozen ice. Existing evaporator structures are quite complex. For example, Chinese utility model patent CN217110115U discloses an evaporator and refrigeration shaft structure for a frozen ice machine. However, its air inlet and outlet are both located radially on the refrigeration shaft, forming an angle between them. This structure is overly complex and cumbersome to manufacture and install, resulting in low production efficiency and incompatibility with other frozen ice machine models, leading to high production costs. Therefore, there is a need to develop a simplified evaporator structure that is easy to manufacture and install and suitable for commercially available frozen ice machines, facilitating its widespread adoption in the industry.

[0003] There are many parts. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structure for an evaporator in a snow ice machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An evaporator structure for a slush ice machine includes an evaporator drum and a cooling shaft component. One end of the evaporator drum is connected to an external power source, and the other end is fitted over the cooling shaft component. The evaporator drum and the cooling shaft component are sealed together by a sealing movable component. One end of the cooling shaft component has an air inlet and an air return port, and the other end has an air outlet. The air return port and the air outlet are interconnected. The air inlet and air return port are respectively arranged in the radial and axial directions of the cooling shaft component, or respectively in the axial and radial directions of the cooling shaft component, but they are not directly connected to each other. The cooling shaft component has an air jet hole, which communicates with the air inlet.

[0007] Furthermore, one end of the evaporator drum is provided with a first connecting shaft, which is hollow and communicates with the sealed end of the evaporator drum; the first connecting shaft is provided with a locking hole, and one end of the fastener enters the interior of the first connecting shaft through the locking hole and abuts against the connecting shaft of the external power source, thereby fixing the connecting shaft of the external power source inside the first connecting shaft.

[0008] Furthermore, the fastener has an external thread on its outer wall and an internal thread on its locking hole that matches the external thread; the two are installed by threaded engagement.

[0009] Furthermore, the other end of the evaporator drum is provided with a second connecting shaft, which is hollow and communicates with the interior of the evaporator drum; the second connecting shaft is sleeved on the sealing movable member and is sealed and movably connected to the refrigeration shaft component.

[0010] Furthermore, the sealing assembly includes a bearing and a sealing sleeve. The bearing and the sealing sleeve are coaxially sleeved on the refrigeration shaft component. The bearing is installed inside the evaporator drum to cooperate with the rotation of the evaporator drum. The sealing sleeve is located at the front end of the bearing and is sleeved inside the evaporator drum to achieve a seal.

[0011] Furthermore, the end of the return air port away from the refrigeration shaft component is provided with a return air interface, which is gradually narrowed in a "trumpet shape" so that the inner diameter of the return air interface is smaller than the inner diameter of the return air port.

[0012] Furthermore, the end of the air inlet away from the cooling shaft component is provided with an air inlet interface, which is "trumpet-shaped" and gradually narrows outward, so that the inner diameter of the air inlet interface is smaller than the inner diameter of the air inlet.

[0013] Furthermore, a limiting step is provided at the end of the first connecting shaft away from the evaporator drum. The limiting step is coaxially arranged with the first connecting shaft and the outer diameter of the limiting step is smaller than the outer diameter of the first connecting shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. The air inlet is set in the radial direction of the refrigeration shaft, while the air outlet is set in the axial direction of the refrigeration shaft. This structure facilitates demolding during production, and the structure is more reasonable, which facilitates the layout and connection of the connecting pipes inside the shaved ice machine.

[0016] 2. The first connecting shaft is provided with a locking hole and fasteners are installed to limit and fix the external power source connecting shaft, so as to prevent axial movement during operation, which could lead to dislocation and damage to parts.

[0017] 3. The structure of the cooling shaft is more streamlined, as detailed in the instruction manual. Attached Figure Description

[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1-Figure 4 As shown, an evaporator structure for a slush ice machine, installed on the machine for condensation and ice making, includes an evaporator drum 1 and a refrigeration shaft component 2. One end of the evaporator drum 1 is connected to an external power source, and the other end is fitted over the refrigeration shaft component 2. In this embodiment, the external power source is preferably a motor, which drives the evaporator drum 1 to rotate. The evaporator drum 1 and the refrigeration shaft component 2 are sealed together by a sealing movable component 3.

[0032] One end of the evaporator drum 1 is provided with a first connecting shaft 11, and the end of the first connecting shaft 11 away from the evaporator drum 1 is provided with a limiting step 13. The limiting step 13 is coaxially arranged with the first connecting shaft 11 and the outer diameter of the limiting step 13 is smaller than the outer diameter of the first connecting shaft 11. The limiting step 13 is used to install a flange (not shown in the figure) and limit the flange.

[0033] The evaporator drum 1 has a second connecting shaft 12 at the end away from the first connecting shaft 11. A sealing ring 121 is fitted on the second connecting shaft 12, and it is mounted on the shaved ice machine through flanges, snap rings, bearings, etc., to achieve a fixed installation. It works in conjunction with an external power source to achieve transmission. This fixing and transmission structure is existing technology and should be understood by those skilled in the art, so it will not be described in detail in this embodiment. It should be noted that in this embodiment, the first connecting shaft 11, the evaporator drum 1, and the second connecting shaft 12 are all coaxially arranged.

[0034] Further, such as Figure 4As shown, the first connecting shaft 11 is hollow for insertion into the connecting shaft of an external power source. The first connecting shaft 11 has a locking hole 111. One end of the fastener 4 enters the first connecting shaft 11 through the locking hole 111 and abuts against the connecting shaft of the external power source, locking the connecting shaft of the external power source and fixing it inside the first connecting shaft 11, thus realizing the transmission of the external power source to the evaporator drum 1. Specifically, the outer wall of the fastener 4 has an external thread 41, and the locking hole 111 has an internal thread 112 that matches the external thread 41. The depth of the fastener 4 entering the first connecting shaft 11 is adjusted by the threads. Furthermore, in order to lock the connecting shaft of the external power source, ensure the tight connection between the external power source and the first connecting shaft 11, prevent it from moving axially during operation and causing dislocation, and at the same time increase the contact area between the fastener 4 and the connecting shaft of the external power source, and make them more tightly connected, the connecting shaft of the external power source is provided with a limiting surface 5, and the end of the connecting shaft of the external power source away from the external power source is provided with a limiting protrusion 51. The limiting surface 5 is a plane, and the cross-section of the external power source connecting shaft at the limiting surface 5 is "D" shaped and matches the bottom end of the fastener 4. During installation, the fastener 4 is screwed downwards into the first connecting shaft 11 until its bottom end abuts against the limiting surface 5. At this time, the downward force of the fastener 4 limits the external power source connecting shaft in the radial direction, while the cooperation between the limiting protrusion 51 and the fastener 4 limits the external power source connecting shaft in the axial direction, thereby fixing the external power source connecting shaft in the first connecting shaft 11. When it rotates, it drives the first connecting shaft 11 to rotate, that is, drives the evaporator drum 1 to rotate.

[0035] Furthermore, the second connecting shaft 12 is hollow and communicates with the interior of the evaporator drum 1; the second connecting shaft 12 is sleeved on the sealing movable member 3 and is sealed and movably connected to the refrigeration shaft member 2.

[0036] Further, such as Figure 2 , Figure 3As shown, the sealing assembly 3 includes a bearing 30 and a sealing sleeve 31. The bearing 30 and the sealing sleeve 31 are coaxially fitted onto the refrigeration shaft component 2. The bearing 30 is installed inside the evaporator drum 1 to cooperate with the rotation of the evaporator drum 1. The sealing sleeve 31 is located at the front end of the bearing 30 and is fitted inside the evaporator drum 1 to achieve a seal. Specifically, both the bearing 30 and the sealing sleeve 31 are installed inside the second connecting shaft 12, and the outer diameter of the sealing sleeve 31 is equal to the outer diameter of the bearing 30. It is tightly fitted against the front end of the bearing 30 to prevent axial movement of the bearing 30 on the refrigeration shaft component 2, thus playing a limiting role. This ensures the installation stability and precise positioning between the refrigeration shaft component 2 and the evaporator drum 1, ensuring that both can work normally, thereby extending the service life of the shaved ice machine. Meanwhile, since the sealing sleeve 31 is made of rubber or silicone, it has elastic and stretchable properties. When the evaporator drum 1 rotates, its elasticity can increase wear compensation and can be used to seal between the second connecting shaft 12 and the refrigeration shaft component 2, preventing refrigerant in the evaporator drum 1 from leaking out from the space between the evaporator drum 1 and the refrigeration shaft component 2. Furthermore, the outer surface of the sealing sleeve 31 is provided with several outer grooves 311. The outer grooves 311 are arranged around the circumference of the sealing sleeve 31, reducing the adhesion of the sealing sleeve 31 to the inner wall of the evaporator drum 1, ensuring the normal rotation of the evaporator drum 1. At the same time, the outer grooves 311 also act as partitions, dividing the sealing sleeve 31 into several sealing rings. Utilizing the elastic properties of its material, these rings seal the space between the second connecting shaft 12 and the refrigeration shaft component 2 respectively, further improving the sealing performance.

[0037] The exhaust pipe 25 has an inlet 21 and a return port 22 at one end, and an outlet 23 at the other end. The return port 22 and the outlet 23 are coaxially arranged and interconnected. Specifically, the inlet 21 is connected to an external compressor via a pipe, and the return port 22 is connected to an external refrigeration tank via a pipe. To facilitate installation and ensure smooth piping between connections, the inlet 21 is arranged radially in the refrigeration shaft component 2, and the return port 22 is arranged axially in the refrigeration shaft component 2. Compared with existing refrigeration shafts, this design simplifies the structure, makes production and installation faster, and achieves high efficiency, practicality, ease of processing, and improved production efficiency.

[0038] Furthermore, to improve the sealing and stability of the connection between the refrigeration shaft component 2 and the compressor and refrigeration tank, a return gas interface 222 is provided at the end of the return gas port 22 away from the refrigeration shaft component 2. The return gas interface 222 is gradually narrowed in a "trumpet shape," making its inner diameter smaller than that of the return gas port 22. Similarly, an air inlet interface 211 is provided at the end of the air inlet 21 away from the refrigeration shaft component 2. The air inlet interface 211 is gradually narrowed outwards in a "trumpet shape," making its inner diameter smaller than that of the air inlet 21. This design effectively limits the movement of the interconnected pipes, preventing axial or radial movement. Moreover, both the return gas interface 222 and the air inlet interface 211 are preferably fixed to the pipes by welding.

[0039] The cooling shaft component 2 is provided with a jet hole 24, which is connected to the air inlet 21.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. All technical solutions that those skilled in the art can obtain based on the concept of the present utility model and on the basis of the prior art through logical analysis, reasoning or limited experiments should be within the protection scope determined by the claims.
