[0033] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "inner," "outer," "vertical," "horizontal," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0036] Figure 1 This is a schematic diagram of the structure of a drum evaporator 100' in the related art. Please refer to the related art for further details. Figure 1 The evaporator 100' includes a drum 1', a feed pipe 2', and a discharge pipe 3'. The drum 1' and feed pipe 2' are rotatably connected, as are the drum 1' and discharge pipe 3'. The feed pipe 2' is used to introduce the refrigerant, which is sprayed onto the inner wall of the drum 1', causing it to evaporate and form a gaseous state. The gaseous refrigerant is discharged to the outside through the discharge pipe 3'. During evaporation, the refrigerant absorbs heat from the drum. When the outer surface of the drum 1' comes into contact with the liquid, the liquid on the outer surface of the drum 1' condenses into ice. To reduce the risk of refrigerant leakage, dynamic sealing rings 4' are installed between the drum 1' and feed pipe 2', and between the drum 1' and discharge pipe 3'.

[0037] However, in related technologies, because the roller 1' needs to rotate continuously, the dynamic seal ring 4' is prone to wear, which leads to a deterioration in the sealing performance between the roller 1' and the feed pipe 2' or between the roller 1' and the discharge pipe 3', thereby increasing the risk of leakage of the cold medium.

[0038] To at least partially solve the above problems, this application provides an evaporator and ice-making equipment that can reduce the risk of refrigerant leakage.

[0039] The specific structure and function of this application will be described in detail below.

[0040] Please see Figure 2 and Figure 4The evaporator 100 includes a refrigeration stator 10, a refrigeration rotor 11, a heat-conducting rod 12, a feed pipe 13, and an exhaust pipe 14. The refrigeration rotor 11 is sleeved on the refrigeration stator 10, and at least a portion of the refrigeration stator 10 is housed inside the refrigeration rotor 11. The refrigeration rotor 11 is configured to rotate relative to the refrigeration stator 10. The heat-conducting rod 12 is disposed between the refrigeration stator 10 and the refrigeration rotor 11, and both the refrigeration stator 10 and the refrigeration rotor 11 abut against the heat-conducting rod 12, so that heat can be transferred between the refrigeration stator 10 and the refrigeration rotor 11 through the heat-conducting rod 12. The feed pipe 13 is at least partially inserted into the interior of the refrigeration stator 10. The feed pipe 13 is used to introduce a cold medium, so that the cold medium evaporates into a gas inside the refrigeration stator 10, thereby absorbing heat from inside the refrigeration stator 10. That is, the cold medium absorbs heat from the refrigeration rotor 11 in sequence through the refrigeration stator 10 and the heat-conducting rod 12, thereby causing the liquid on the surface of the refrigeration rotor 11 to condense into ice. The exhaust pipe 14 is located in the refrigeration stator 10. When the refrigerant evaporates in the refrigeration stator 10 to form gas, the gas can be discharged from the exhaust pipe 14.

[0041] For the aforementioned cooling stator 10, please refer to... Figure 2 and Figure 4 The refrigeration stator 10 is generally cylindrical and includes an evaporation chamber 101 and a first peripheral wall 102, which forms part of the boundary of the evaporation chamber 101. A feed pipe 13 is at least partially housed within the evaporation chamber 101, and the portion of the feed pipe 13 housed within the evaporation chamber 101 has an outlet 131, allowing the refrigerant to flow out from the outlet 131 and contact the first peripheral wall 102. When the refrigerant contacts the first peripheral wall 102, it absorbs heat from the refrigeration stator 10 and evaporates into a gas. The aforementioned exhaust pipe 14 communicates with the evaporation chamber 101, allowing the gaseous refrigerant to be discharged from the exhaust pipe 14.

[0042] In some embodiments, the portion of the feed pipe 13 housed in the evaporation chamber 101 is provided with a plurality of discharge ports 131, which are spaced apart. By providing a plurality of discharge ports 131, it is beneficial to spray the refrigerant more evenly onto the first peripheral wall 102.

[0043] For the aforementioned refrigeration rotor 11, please refer to... Figure 2 and Figure 4The refrigeration rotor 11 is generally cylindrical and has a second peripheral wall 111. A first peripheral wall 102 is located inside the second peripheral wall 111. Specifically, the second peripheral wall 111 is located outside the first peripheral wall 102 and surrounds the first peripheral wall 102 when viewed along the axial direction of the refrigeration rotor 11. A thermally conductive gap is formed between the first peripheral wall 102 and the second peripheral wall 111. The aforementioned heat-conducting rod 12 is located within the thermally conductive gap. One end of the heat-conducting rod 12 abuts against the first peripheral wall 102, and the other end abuts against the second peripheral wall 111. The heat-conducting rod 12 can rotate relative to the first peripheral wall 102 and the second peripheral wall 111. Therefore, during the rotation of the refrigeration rotor 11, the friction between the heat-conducting rod 12 and the first peripheral wall 102, as well as between the heat-conducting rod 12 and the second peripheral wall 111, can be reduced. When the cooling medium evaporates at the first peripheral wall 102, it can absorb heat from the second peripheral wall 111 through the first peripheral wall 102 and the heat-conducting rod 12 in sequence. The surface of the second peripheral wall 111 facing away from the first peripheral wall 102 is used to contact the liquid, thereby condensing the liquid on the outer surface of the second peripheral wall 111 into ice. In this embodiment, by sleeved refrigeration rotor 11 on refrigeration stator 10, and by allowing refrigeration rotor 11 to rotate relative to refrigeration stator 10, and by housing at least a portion of feed pipe 13 in evaporation chamber 101, and by communicating exhaust pipe 14 with evaporation chamber 101, neither feed pipe 13 nor exhaust pipe 14 needs to rotate relative to refrigeration stator 10. This helps reduce the risk of wear between feed pipe 13 and refrigeration stator 10, and between exhaust pipe 14 and refrigeration stator 10, and improves the sealing performance between feed pipe 13 and refrigeration stator 10, and between exhaust pipe 14 and refrigeration stator 10, thereby reducing the risk of refrigerant leakage. In addition, by providing heat-conducting rod 12 between the first peripheral wall 102 and the second peripheral wall 111, with both the first peripheral wall 102 and the second peripheral wall 111 abutting against the heat-conducting rod 12, the heat-conducting rod 12 can improve the heat transfer efficiency between the first peripheral wall 102 and the second peripheral wall 111, thereby improving ice-making efficiency.

[0044] In some embodiments, the surface of the heat-conducting rod 12 is coated with lubricating oil, thereby reducing the friction between the heat-conducting rod 12 and the first peripheral wall 102 and between the heat-conducting rod 12 and the second peripheral wall 111, and reducing the wear of the heat-conducting rod 12, the first peripheral wall 102 and the second peripheral wall 111.

[0045] In some embodiments, please refer to Figure 4 and Figure 5The system comprises multiple heat-conducting rods 12, all housed within the aforementioned heat-conducting gap, and spaced apart along the circumferential direction of the first peripheral wall 102. One end of each heat-conducting rod 12 abuts against the first peripheral wall 102, and the other end abuts against the second peripheral wall 111. Each heat-conducting rod 12 is rotatable relative to both the first and second peripheral walls 102 and 111. In this embodiment, by providing multiple heat-conducting rods 12, the heat transfer efficiency between the first and second peripheral walls 102 can be improved. The spaced distribution of multiple heat-conducting rods along the circumferential direction of the first peripheral wall 102 helps improve the coaxiality between the cooling rotor 11 and the cooling stator 10 during rotation, thereby enhancing the stability of the cooling rotor 11 during rotation.

[0046] In some embodiments, please refer to Figure 4 The refrigeration rotor 11 is provided with a top wall 112 and a bottom wall 113, which are arranged opposite to each other. The top wall 112 is connected to one end of the second peripheral wall 111, and the bottom wall 113 is connected to the other end of the second peripheral wall 111. The top wall 112, the second peripheral wall 111, and the bottom wall 113 together enclose a receiving cavity 114, in which the refrigeration stator 10 is at least partially housed.

[0047] Specifically, the first peripheral wall 102 of the cooling stator 10 is housed in the receiving cavity 114.

[0048] It is worth noting that the ice on the outer surface of the second peripheral wall 111 is usually scraped off by an ice scraper 700. Specifically, the ice scraper 700 is fixed at a predetermined distance from the second peripheral wall 111. As the refrigeration rotor 11 rotates, the ice scraper 700 can scrape off the ice on the second peripheral wall 111. In related technologies, since the refrigerant absorbs heat from both the top wall 112 and the bottom wall 113 during the evaporation process in the evaporation chamber 101, when there is liquid or water vapor on the surface of the top wall 112 or the bottom wall 113, ice is easily formed on the surface of the top wall 112 or the bottom wall 113, which increases the load on the refrigeration rotor 11 and thus increases energy consumption.

[0049] To at least partially solve the above problems, in some embodiments, the evaporator 100 further includes a first heat insulation member 15. The first heat insulation member 15 is disposed on the side of the top wall 112 near the bottom wall 113 and is located between the top wall 112 and the refrigeration stator 10. The first heat insulation member 15 is used to block heat transfer between the top wall 112 and the refrigeration stator 10, thereby reducing the risk of icing at the top wall 112, and further reducing the risk of increased load on the refrigeration rotor 11, which is beneficial to reducing the energy consumption of the evaporator 100.

[0050] In some embodiments, the evaporator 100 further includes a second heat insulation member 16, which is disposed on the side of the bottom wall 113 near the top wall 112 and is located between the bottom wall 113 and the refrigeration stator 10. The second heat insulation member 16 is used to block heat transfer between the bottom wall 113 and the refrigeration stator 10, thereby reducing the risk of icing at the bottom wall 113 and further reducing the risk of increased load on the refrigeration rotor 11, which is beneficial to reducing the energy consumption of the evaporator 100.

[0051] In some embodiments, the first insulation element 15 is made of foam.

[0052] In some embodiments, the second insulation element 16 is made of foam.

[0053] In some embodiments, please refer to Figure 4 The refrigeration stator 10 is provided with a rotating shaft portion 104, which passes through the top wall 112 and at least partially protrudes from the side of the top wall 112 away from the bottom wall 113, so as to fix the rotating shaft portion 104 to other components (such as the housing, bracket, etc. of the ice-making equipment). The top wall 112 and the rotating shaft portion 104 are rotatably engaged so that the refrigeration rotor 11 can rotate around the rotating shaft portion 104.

[0054] In some embodiments, the feed pipe 13 passes through the rotating shaft portion 104, and at least a portion of the feed pipe 13 is housed in the evaporation chamber 101 after passing through the rotating shaft portion 104. That is, the feed pipe 13 extends from the rotating shaft portion 104 into the evaporation chamber 101. This arrangement can reduce the risk of the feed pipe 13 interfering with the rotation of the refrigeration rotor 11.

[0055] In some embodiments, the exhaust pipe 14 is at least partially inserted into the rotating shaft portion 104 and communicates with the evaporation chamber 101, so that the refrigerant, after evaporating into gas in the evaporation chamber 101, can be discharged from the exhaust pipe 14. By providing the exhaust pipe 14 in the rotating shaft portion 104, the risk of the exhaust pipe 14 interfering with the rotation of the refrigeration rotor 11 can be reduced.

[0056] In some embodiments, a heat insulation layer (not shown) is provided between the feed pipe 13 and the exhaust pipe 14. The heat insulation layer is used to prevent heat transfer between the feed pipe 13 and the exhaust pipe 14, which helps to reduce the transfer of cold energy of the cold medium in the feed pipe 13 to the exhaust pipe 14, thereby reducing the risk of frost forming inside the exhaust pipe 14 and clogging the exhaust pipe 14.

[0057] In some embodiments, please refer to Figure 4 and Figure 6The evaporator 100 includes a first bearing 17, which is sleeved on the rotating shaft 104 and is also connected to the top wall 112 so that the refrigeration rotor 11 can be rotatably connected to the rotating shaft 104 through the first bearing 17.

[0058] In some embodiments, the first bearing 17 is provided with a first bearing inclined surface 171 at the end away from the bottom wall 113, and the top wall 112 is provided with a first limiting inclined surface 1121 at the end near the bottom wall 113. The first bearing inclined surface 171 and the first limiting inclined surface 1121 abut against each other. With this arrangement, the first bearing inclined surface 171 can restrict the sliding of the refrigeration rotor 11 along the shaft portion 104, which is beneficial to improving the stability of the refrigeration rotor 11 rotating around the shaft portion 104.

[0059] In some embodiments, please refer to Figure 4 and Figure 7 The cooling stator 10 has a positioning protrusion 105 at the end away from the rotating shaft 104, and the cooling rotor 11 has a positioning groove 1131 at the end of the bottom wall 113 near the top wall 112. The positioning protrusion 105 is at least partially received in the positioning groove 1131, and the positioning protrusion 105 and the positioning groove 1131 are rotatably engaged. In this embodiment, by providing the positioning protrusion 105 and the positioning groove 1131, the positioning between the cooling stator 10 and the cooling rotor 11 is facilitated, thereby facilitating the assembly of the cooling stator 10 and the cooling rotor 11. In addition, the rotatable engagement between the positioning protrusion 105 and the positioning groove 1131 helps to improve the stability of the cooling rotor 11 during rotation.

[0060] In some embodiments, the positioning protrusion 105 is coaxial with the rotating shaft portion 104.

[0061] In some embodiments, please refer to Figure 4 and Figure 7 The evaporator 100 also includes a second bearing 18, which is at least partially housed in the positioning groove 1131 and sleeved on the positioning protrusion 105. This arrangement helps to further improve the stability of the refrigeration rotor 11 during rotation relative to the refrigeration stator 10.

[0062] In some embodiments, the positioning protrusion 105 is provided with a second limiting slope 1051, and the end of the second bearing 18 near the top wall 112 is provided with a second bearing slope 181. The second bearing slope 181 abuts against the second limiting slope 1051 so that the second limiting slope 1051 can restrict the refrigeration rotor 11 from sliding along the first direction X through the second bearing 18, which is beneficial to improving the stability of the refrigeration rotor 11 during rotation. The first direction X is parallel to the axis of the refrigeration stator 10.

[0063] In some embodiments, a third limiting slope 182 is provided at the end of the second bearing 18 away from the top wall 112, and a third bearing slope 1133 is provided at the end of the bottom wall 113 near the top wall 112. The third bearing slope 1133 forms part of the inner wall of the positioning groove 1131. The third limiting slope 182 abuts against the third bearing slope 1133 so that the third bearing slope 1133 carries the second bearing 18, and the third bearing slope 1133 can generate a force on the second bearing 18. One component of this force is directed toward the top wall 112. This component is balanced with the component force generated by the positioning protrusion 105 on the second bearing 18 in the axial direction of the cooling stator 10, thereby limiting the risk of the second bearing 18 moving in the axial direction of the cooling stator 10.

[0064] In some embodiments, a drive shaft 1132 is provided at one end of the bottom wall 113 of the refrigeration rotor 11 away from the top wall 112. The drive shaft 1132 is coaxial with the rotating shaft 104 and is used to connect to the output shaft (not shown) of the motor so that the motor can drive the refrigeration rotor 11 to rotate through the drive shaft 1132.

[0065] In this embodiment, by sleeved refrigeration rotor 11 on refrigeration stator 10, and by allowing refrigeration rotor 11 to rotate relative to refrigeration stator 10, and by housing at least a portion of feed pipe 13 within evaporation chamber 101, and by communicating exhaust pipe 14 with evaporation chamber 101, neither feed pipe 13 nor exhaust pipe 14 needs to rotate relative to refrigeration stator 10. This reduces the risk of wear between feed pipe 13 and refrigeration stator 10, and between exhaust pipe 14 and refrigeration stator 10, and improves the sealing performance between feed pipe 13 and refrigeration stator 10, and between exhaust pipe 14 and refrigeration stator 10, thereby reducing the risk of refrigerant leakage. In addition, by providing heat-conducting rod 12 between the first peripheral wall 102 and the second peripheral wall 111, with both the first peripheral wall 102 and the second peripheral wall 111 abutting against the heat-conducting rod 12, the heat-conducting rod 12 can improve the heat transfer efficiency between the first peripheral wall 102 and the second peripheral wall 111, thereby improving ice-making efficiency and reducing cold loss.

[0066] This application also provides embodiments of ice-making equipment; please refer to [link / reference]. Figure 4 and Figure 8The ice-making equipment includes a compressor 200, a condenser 300, a throttle valve 400, and the aforementioned evaporator 100. The outlet of the compressor 200 is connected to the inlet of the condenser 300, the inlet of the throttle valve 400 is connected to the outlet of the condenser 300, the feed pipe 13 is connected to the outlet of the throttle valve 400, and the exhaust pipe 14 is connected to the inlet of the compressor 200. The refrigerant is compressed into a high-temperature, high-pressure gas in the compressor 200. When it flows into the condenser 300, the condenser 300 condenses the high-temperature, high-pressure gas into a high-pressure, low-temperature liquid. This liquid then flows into the throttle valve 400 to form a low-temperature, low-pressure liquid, which then flows into the evaporation chamber 101 of the evaporator 100 and evaporates back into gas. The gas then flows back into the compressor 200 through the exhaust pipe 14, forming a circulating flow of the refrigerant. During the evaporation of the refrigerant in the evaporator 100, it absorbs heat from the refrigeration rotor 11, causing the liquid on the surface of the second peripheral wall 111 of the refrigeration rotor 11 to condense into ice, thus achieving ice production.

[0067] In some embodiments, the ice-making apparatus includes a water tank 600 for storing water. The second peripheral wall 111 of the refrigeration rotor 11 is at least partially housed in the water tank 600 such that the outer surface of the second peripheral wall 111 can contact the water in the water tank 600, thereby freezing the water into ice.

[0068] In some embodiments, please refer to Figure 9 The ice-making equipment also includes a mounting bracket 500 and an ice scraper 700. The ice scraper 700 is fixed at a preset distance from the second peripheral wall 111 so that when the refrigeration rotor 11 rotates, the ice scraper 700 can scrape the ice off the second peripheral wall 111 without having to manually scrape it off.

[0069] In some embodiments, the preset distance can be 0.1 to 1 cm.
