Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, specifically to an ice maker evaporator. Background Technology

[0002] With the popularity of cold drinks, ice makers, as a device for making ice cubes, have been widely used. When making ice, the refrigerant exchanges heat with room temperature water, causing the room temperature water to condense into ice cubes. The condensed ice cubes can be added to different drinks to meet users' needs for cold drinks. The evaporator is the "heart" of the ice maker, and its performance directly determines the ice-making efficiency, energy consumption, and equipment lifespan.

[0003] A prior patent (publication number: CN211233489U) discloses a drum-type ice maker, comprising a rotatable drum shell and a conveying pipe for conveying refrigerant; characterized in that: a heat exchange jacket is provided on the drum shell, and the conveying pipe is at least partially covered by the heat exchange jacket; one or both ends of the conveying pipe are coaxially engaged with the drum shell, and one or both ends of the conveying pipe are exposed outside the drum shell and connected to a rotary joint; the conveying pipe is arranged in a coil form inside the heat exchange jacket. Alternatively, the conveying pipe is arranged in a tubular form inside the heat exchange jacket. Alternatively, a heat exchange chamber is provided inside the heat exchange jacket; the conveying pipe includes an inlet pipe and an outlet pipe; the inlet end of the inlet pipe is connected to the rotary joint, and the outlet end of the inlet pipe is connected to the heat exchange chamber; the inlet end of the outlet pipe is connected to the heat exchange chamber, and the outlet end of the outlet pipe is connected to the rotary joint.

[0004] Although the aforementioned patent allows the refrigerant to pass through different positions on the heat exchange jacket under the guidance of the delivery pipe, and the refrigerant's delivery trajectory is controllable, the refrigerant uses the heat exchange jacket to uniformly absorb heat and make ice, effectively ensuring the uniformity of ice making, and the area on the drum shell that can make ice is large; the refrigerant energy loss during the initial delivery process is small, thereby improving the refrigerant utilization rate and enhancing the ice-making effect, it still has certain shortcomings in use. The refrigerant is introduced into the heat exchange jacket through the inlet pipe and then flows out through the outlet pipe. During this period, some refrigerant does not fully contact the heat exchange jacket before flowing out from the outlet pipe, resulting in uneven cooling inside the heat exchange jacket, which in turn leads to uneven cooling of the heat exchange layer and affects the overall ice-making effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an evaporator for an ice maker, which has the advantage of uniform cooling and solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an evaporator for an ice maker, comprising an outer cylinder, an inner cylinder disposed inside the outer cylinder, a sleeve fitted onto the outer side of the inner cylinder, a cavity disposed between the inner cylinder and the sleeve, the sleeve being inserted into the outer cylinder, two vent holes being formed on the outer surface of the sleeve, the vent holes being connected to the cavity, two spiral pipes disposed inside the outer cylinder, multiple exhaust ports being formed on the outer side of the spiral pipes along the spiral direction, a vertical pipe being fixedly connected to the air inlet end of the spiral pipe, a sealing ring being installed at the end of the vertical pipe, and the vertical pipe being connected to its corresponding vent hole.

[0007] Furthermore, a movable ring is fitted onto the outer surface of the sleeve, and slots are provided at both ends of the movable ring. The vertical pipe is fixed to the movable ring through the slots.

[0008] The above scheme allows the movement of the moving ring to move the vertical pipe, which in turn moves the spiral pipe, thus facilitating the loading and unloading of the spiral pipe.

[0009] Furthermore, two sets of supports are fixed to the outer surface of the movable ring, and the other end of each set of supports is fixed to its corresponding spiral pipe.

[0010] The above method uses brackets to support and fix the spiral pipe, maintaining its stability during use.

[0011] Furthermore, a slider is fixed to the outer surface of the sleeve, and a groove is formed on the inner wall of the movable ring, with the slider slidably connected to the groove.

[0012] The above scheme limits the movement of the ring by sliding the slider and the groove, preventing it from rotating around the sleeve and maintaining the stability of the ring.

[0013] Furthermore, a fixing ring is fixed to the outer surface of the sleeve, and a mounting groove is provided on the side of the fixing ring and the moving ring that are close to each other, and a magnet is installed in the mounting groove.

[0014] With the above scheme, when the moving ring moves to one end and contacts the fixed ring, the vertical pipe is connected to the corresponding vent.

[0015] Furthermore, a side plate is installed at the left end of the outer cylinder, and a bracket corresponding to the output end of the external drive device is fixed on the left side of the side.

[0016] The above scheme uses an external drive device to rotate the side plate, which in turn drives the outer cylinder to rotate.

[0017] Furthermore, an air inlet pipe is fixed to the right end of the sleeve, the air inlet pipe is connected to the cavity, and the other end of the air inlet pipe is connected to an external pump.

[0018] Through the above method, an external pump delivers refrigerant to the intake pipe and into the cavity through the intake pipe.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This ice maker evaporator uses an external pump to deliver refrigerant into the cavity between the inner cylinder and the outer sleeve. The refrigerant then enters the corresponding spiral pipe through a vent and is discharged through multiple exhaust ports on the outer surface of the spiral pipe. The exhaust ports face the inner wall of the outer cylinder, and in conjunction with the rotation of the outer cylinder during use, ensures that the inner wall of the outer cylinder is in contact with the refrigerant, thereby achieving uniform cooling of the outer cylinder and avoiding cooling dead zones.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3 An ice maker evaporator in this embodiment includes an outer cylinder 1, an inner cylinder 2 inside the outer cylinder 1, a sleeve 3 fitted onto the outer side of the inner cylinder 2, and a cavity between the inner cylinder 2 and the sleeve 3. The left end of the inner cylinder 2 is located inside the outer cylinder 1, and the right end of the inner cylinder 2 is connected to an external collection device. The sleeve 3 is inserted into the outer cylinder 1, and two vent holes 4 are opened on the outer surface of the sleeve 3. The vent holes 4 are connected to the cavity. Two spiral pipes 5 are arranged inside the outer cylinder 1. Multiple exhaust ports 6 are opened on the outer side of the spiral pipes 5 along the spiral direction. The air inlet end of the spiral pipe 5 is fixedly connected to a vertical pipe 7. A sealing ring is installed at the end of the vertical pipe 7, and the vertical pipe 7 is connected to its corresponding vent hole 4.

[0031] Please see Figure 3 , Figure 4 and Figure 5 A movable ring 8 is fitted onto the outer surface of the sleeve 3. The movable ring 8 has slots at both ends. The vertical pipe 7 is fixed to the movable ring 8 through the slots. The movement of the movable ring 8 can drive the vertical pipe 7 to move, thereby driving the spiral pipe 5 to move, which facilitates the loading and unloading of the spiral pipe 5. Two sets of brackets 9 are fixed on the outer surface of the movable ring 8. The other end of each set of brackets 9 is fixed to its corresponding spiral pipe 5. The brackets 9 support and fix the spiral pipe 5 to maintain the stability of the spiral pipe 5 during use.

[0032] Please see Figure 3 , Figure 4 and Figure 6 A slider 10 is fixed on the outer surface of the sleeve 3. A groove is provided on the inner wall of the moving ring 8. The slider 10 is slidably connected to the groove. The sliding connection between the slider 10 and the groove limits the movement of the moving ring 8, preventing it from rotating around the sleeve 3 and maintaining the stability of the moving ring 8. A fixed ring 11 is fixed on the outer surface of the sleeve 3. An installation groove is provided on the side of the fixed ring 11 that is close to the moving ring 8. A magnet block 12 is installed in the installation groove. When the moving ring 8 moves to one end and contacts the fixed ring 11, the vertical pipe 7 is connected to the corresponding vent hole 4.

[0033] Please see Figure 3 , Figure 4 and Figure 5 A side plate 13 is installed on the left end of the outer cylinder 1. A bracket 14 corresponding to the output end of the external drive device is fixed on the left side of the side. The external drive device drives the side plate 13 to rotate, thereby driving the outer cylinder 1 to rotate. An air inlet pipe 15 is fixed on the right end of the sleeve 3. The air inlet pipe 15 is connected to the cavity. The other end of the air inlet pipe 15 is connected to an external pump. The external pump pumps the refrigerant to the air inlet pipe 15 and into the cavity through the air inlet pipe 15.

[0034] It should be noted that during use, the refrigerant flow and inlet pressure must be strictly controlled according to the design requirements. Before the first operation, it is necessary to check whether there are any leaks in the refrigerant pipeline to avoid a sudden drop in ice-making efficiency due to insufficient refrigerant. At the same time, the pumping pressure of the pump should be adjusted so that each exhaust port can discharge refrigerant.

[0035] The working principle of the above embodiment is as follows: During use, the refrigerant is pumped to the inlet pipe 15 by an external pump. The refrigerant reaches the cavity between the inner pipe and the sleeve through the inlet pipe 15, and then enters the vertical pipe 7 through the vent hole 4. The sealing ring installed at the end of the vertical pipe 7 can prevent the refrigerant from leaking directly into the interior of the outer cylinder 1. The refrigerant enters the spiral pipe 5 along the vertical pipe 7. Under the pressure, the refrigerant is discharged from the exhaust port 6 of the spiral pipe 5. By adjusting the external pumping pressure, the exhaust ports 6 opened on the side of the spiral pipe 5 can discharge the refrigerant. At the same time, the outer cylinder 1 is rotated by an external drive device, so that the inner wall of the outer cylinder 1 must be in contact with the refrigerant, thereby achieving uniform cooling of the outer cylinder 1 and avoiding the occurrence of cooling dead zones. Then the refrigerant in the outer cylinder 1 is discharged through the inner cylinder 2.
