Description

Technical Field

[0001] The present application relates to the technical field of ice making, and in particular to an evaporator of an ice making machine. Background Art

[0002] In the related art, the evaporator of the ice maker usually has a scraper installed in a sleeve, and the bottom of the scraper is connected to a driving assembly for driving the scraper to rotate. Water enters the sleeve from the bottom of the sleeve and forms a water film on the scraper blade. The liquid water film exchanges heat with the refrigerant during the rising process, thereby condensing to form solid ice. Under the push and squeeze of the scraper, the solid ice is squeezed out through the ice head at the top of the sleeve.

[0003] When ice making is finished, the ice at the scraper position inside the sleeve will freeze the scraper. When the ice maker is started again, the scraper cannot rotate, and the ice cubes cannot be squeezed out of the ice head, causing inconvenience to the ice making operation and reducing the ice making efficiency. Utility Model Content

[0004] In order to improve the situation where the scraper is frozen and cannot rotate to push ice, and to improve the ice-making efficiency of the ice-making machine, the present application provides an evaporator for an ice-making machine.

[0005] The present application provides an evaporator for an ice maker, which adopts the following technical solution:

[0006] An evaporator of an ice-making machine comprises a sleeve, a screw scraper arranged inside the sleeve, an ice-discharging head and an ice breaker, wherein the ice-discharging head is coaxially arranged above the sleeve, a water inlet pipe is arranged on the side wall of the sleeve, the water inlet pipe is fixedly connected to the lower part of the sleeve and communicated with the inside of the sleeve, the ice breaker is coaxially arranged with the screw scraper and the ice-discharging head, and the ice breaker passes through the ice-discharging head and is fixedly connected to the screw scraper;

[0007] A first flow channel for water to pass through is opened at the center of the screw scraper, and a water inlet connecting the first flow channel and the inside of the sleeve is provided on the screw scraper;

[0008] A second flow channel communicating with the first flow channel is provided at the center axis of the ice breaker, and a water outlet communicating with the second flow channel is provided on the side wall of the ice breaker.

[0009] By adopting the above technical solution, a first flow channel for water supply is opened at the center of the screw scraper, and a water inlet connecting the first flow channel and the inside of the sleeve is set on the screw scraper. The ice breaker is coaxially arranged with the screw scraper and the ice outlet head, and a second flow channel connected to the first flow channel is opened at the center axis of the ice breaker, and a water outlet is set on the side wall. After the water flows into the inside of the sleeve, it can enter the first flow channel in the center of the screw scraper and the second flow channel in the center of the ice breaker from the water inlet, and then flow out from the water outlet. After the ice maker stops making ice, the screw scraper inside the sleeve is frozen by the icicles. When the ice maker is started again, water from the outlet can fall above the ice-discharging head, flushing the contact surface between the ice and the ice-discharging head to reduce ice adhesion. The water then enters the sleeve from the ice-discharging head to assist in melting the icicles, providing space for the rotation of the screw scraper, improving the situation where the scraper is frozen and cannot rotate to push ice, so that the ice maker can quickly enter the ice-making operation state when it is started again, thereby improving the ice-making efficiency of the ice maker.

[0010] Furthermore, the ice breaker includes an ice-breaking cone platform and a connecting column, the connecting column passes through the ice-discharging head and is fixedly connected to the screw scraper, the ice-breaking cone platform is coaxially arranged and integrally connected to an end of the connecting column away from the screw scraper, and the second flow channel is opened at the center axis position of the connecting column and the ice-breaking cone platform and passes through to the end surface of the ice-breaking cone platform away from the connecting column.

[0011] By adopting the above technical solution, the ice-breaking cone has a gradually expanding shape, and can exert a more uniform force when it contacts the ice. When the ice-breaking cone cuts the ice, it can effectively separate the contact surface between the ice and the ice outlet head, peel the ice from the ice outlet head, and improve the efficiency of ice cutting. The second flow channel runs through the end surface of the ice-breaking cone, which helps to balance the internal air pressure of the first flow channel and the second flow channel, and at the same time ensures that the water flow can directly flush the area where the ice-breaking cone contacts the ice, reducing ice adhesion.

[0012] Furthermore, the sleeve includes a barrel and a mounting seat arranged below the barrel, and a driving seat for driving the screw scraper is coaxially arranged on the mounting seat. The driving seat is rotatably connected to the mounting seat and is located inside the sleeve.

[0013] By adopting the above technical solution, the drive seat is coaxially arranged and rotatably connected to the mounting seat and is located in the sleeve, making the entire drive structure more stable and compact, which helps to reduce the breakage and waste of ice cubes caused by vibration or shaking. The drive seat and the screw scraper ensure that the screw scraper can operate efficiently under the drive of the drive seat, thereby improving the ice making efficiency.

[0014] Furthermore, the screw scraper includes a screw and a spiral push piece fixedly connected to the outer wall of the screw, one end of the screw is coaxially penetrated and fixedly connected to the drive seat, and the connecting column is fixedly connected to the end of the screw away from the drive seat;

[0015] The spiral pushing piece abuts against the inner wall of the cylinder.

[0016] By adopting the above technical solution, the continuous spiral structure of the spiral pushing piece can ensure that the ice cubes are evenly stressed during the pushing process. The spiral pushing piece is tightly in contact with the inner wall of the cylinder. When the screw rotates, the spiral pushing piece can push the ice cubes from the inner wall of the cylinder to the ice outlet head, ensuring that the ice cubes can be pushed out evenly, avoiding the situation where the ice cubes are trapped or blocked in the cylinder, and also reducing the possibility of ice cube breakage and deformation, keeping the shape of the ice cubes intact.

[0017] Furthermore, a spiral groove for water to pass through is provided on the inner wall of the cylinder, and the spiral groove extends spirally along the length direction of the sleeve and is opposite to the spiral direction of the spiral push piece.

[0018] By adopting the above technical solution, after the water flows from the water outlet into the top of the ice outlet head, the spiral groove can provide a spiral flow path for the water flow, so that the water flow can smoothly flow into the space between the inner wall of the sleeve and the icicle, thereby achieving the effect of assisting the melting of the icicle. At the same time, the spirally arranged groove structure can increase the contact area between the water flow and the icicle, thereby improving the ice melting efficiency. The spiral groove and the spiral push piece have opposite rotation directions, thereby preventing the spiral push piece from incorrectly engaging, thereby improving the stability of the equipment.

[0019] Furthermore, the screw is also provided with a thrust ring plate and a support seat for preventing the scraper from moving downward. The thrust ring plate is coaxially arranged and fixedly connected to the lower part of the screw and is located between the spiral push plate and the driving seat. The support seat is sleeved on the lower part of the screw and is rotatably connected to the screw. The support seat abuts between the driving seat and the thrust ring plate.

[0020] By adopting the above technical solution, the thrust ring plate is coaxially arranged and fixedly connected to the lower part of the screw rod to play a stabilizing effect between the spiral push piece and the drive seat. During the operation of the screw scraper, due to the resistance of the ice cubes, the screw scraper will have a tendency to move downward. The thrust ring plate prevents the screw scraper from moving downward through the interaction with the drive seat and the spiral push piece, so that the screw scraper can also remain stable during the rotation operation, avoiding failures caused by vibration or shaking, which helps to improve the pushing efficiency of the screw scraper, thereby improving the overall ice making efficiency of the ice maker.

[0021] Furthermore, a plurality of ice extrusion outlets are formed on the circumferential direction of the ice outlet head, and the ice extrusion outlets are communicated with the sleeve.

[0022] By adopting the above technical solution, a plurality of ice extrusion outlets are opened on the circumference of the ice outlet head, so that ice cubes can be pushed out from the ice outlet head from multiple directions at the same time, thereby improving the ice outlet efficiency, enabling the ice maker to produce a large amount of ice cubes in a short time, thereby improving the overall ice making efficiency of the ice maker and meeting the needs during peak hours.

[0023] Furthermore, the ice-extrusion outlet is provided with an extrusion section and a shaping section in sequence from the side of the ice-extrusion head close to the screw scraper to the side away from the screw scraper, the diameter of the extrusion section gradually decreases, and the diameter of the shaping section is the same as the minimum diameter of the extrusion section.

[0024] By adopting the above technical solution, the diameter of the extrusion section gradually decreases, so that the shape of the ice cube gradually becomes regular when passing through the extrusion section, reducing the irregular protrusions or depressions on the surface of the ice cube. At the same time, the extrusion section can make the ice cube be subjected to a gradually increasing extrusion force when it is pushed out, which helps the ice cube to be smoothly and completely pushed out of the ice outlet head. The ice cube then enters the shaping section with the same diameter as the minimum diameter of the extrusion section, further ensuring the integrity and consistency of the shape of the ice cube. Through the coordinated setting of the extrusion section and the shaping section, the ice cube is fully squeezed and shaped when it is pushed out, making the surface of the ice cube smoother and flatter, and improving the overall quality of the ice cube.

[0025] Furthermore, a notch for guiding ice debris into the extrusion section is provided on one side of the ice outlet head close to the sleeve, and the notch is opened on the wall surface of the extrusion section and is recessed toward one side of the shaping section.

[0026] By adopting the above technical solution, the design of the notch allows the ice debris to be smoothly guided into the extrusion section, and is pushed out after being squeezed into an icicle, thereby preventing the ice debris from being difficult to enter the ice outlet when it is pushed to the ice outlet head, causing uneven distribution of ice debris in the ice outlet or even blockage, reducing the amount of ice debris remaining inside the ice outlet head, and helping to improve the overall ice-making efficiency of the ice maker.

[0027] Furthermore, the thickness of the spiral push piece on the side close to the inner wall of the sleeve is smaller than the thickness of the side where the spiral push piece is connected to the screw rod.

[0028] By adopting the above technical solution, reducing the thickness of the spiral push piece on the side close to the inner wall of the sleeve can reduce the resistance of the ice-water mixture passing through, thereby improving the ice-making efficiency. The thickness of the side of the spiral push piece connected to the screw is sufficient to ensure that the spiral push piece can withstand the torque and thrust from the screw, thereby improving the structural strength of the screw scraper.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:.

[0030] 1. The first flow channel in the center of the screw scraper and the second flow channel in the center of the ice breaker are arranged in coordination, so that water can flow from the inside of the sleeve to the ice breaker, and then flow out through the water outlet and enter the ice outlet to wash and assist in melting the icicles, thereby reducing the adhesion of ice cubes to the inner wall of the sleeve and the screw scraper, and improving the ice making efficiency;

[0031] 2. The spiral push piece is tightly against the inner wall of the cylinder, which can ensure that the ice cubes are pushed out evenly and avoid ice retention or blockage. The spiral groove on the inner wall of the cylinder is opposite to the spiral direction of the spiral push piece, which not only provides a spiral flow path for the water flow and improves the ice melting efficiency, but also prevents the spiral push piece from incorrectly engaging with the sleeve, thereby improving the stability of the equipment.

[0032] 3. The support seat can enhance the connection stability between the screw scraper and the drive seat, and the thrust ring plate prevents the screw scraper from moving downward during operation, ensuring the stable operation of the screw scraper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-4 And embodiments, the present application is further described in detail.

[0039] The embodiment of the present application discloses an evaporator of an ice maker. The expressions such as "upper" and "lower" in the embodiment are all determined with reference to the placement and installation position of the ice maker when it is in normal use.

[0040] Reference Figure 1 and Figure 2 The ice maker comprises a sleeve 1, a screw scraper 2, an ice discharging head 3 and an ice breaker 4. The screw scraper 2 is arranged in the sleeve 1 to push the solid ice upward in a spiral manner, the ice discharging head 3 is installed above the sleeve 1, and the ice breaker 4 passes through the ice discharging head 3 and is fixedly connected to the screw scraper 2.

[0041] The sleeve 1 includes a cylinder 12 and a mounting seat 13. The mounting seat 13 is horizontally arranged to provide a stable mounting base for the ice maker. The cylinder 12 is vertically fixedly connected to the mounting seat 13. A water inlet pipe 11 is vertically fixedly connected to the outer wall of the cylinder 12 close to the mounting seat 13. The water inlet pipe 11 is connected to the inside of the sleeve 1. A drive seat 14 for driving the screw scraper 2 to rotate axially is coaxially arranged on the mounting seat 13. The drive seat 14 is coaxially arranged and rotatably connected to the top of the mounting seat 13.

[0042] The screw scraper 2 includes a screw 21 and a spiral push piece 22, one end of the screw 21 is vertically fixedly connected to the central axis of the drive seat 14. The spiral push piece 22 is integrally connected to the outer wall of the screw 21 and spirally rises along the length direction of the screw 21. The spiral push piece 22 abuts against the inner wall of the cylinder 12, and the thickness of the spiral push piece 22 close to the cylinder 12 is less than the thickness of the side connected to the screw 21.

[0043] A spiral groove 121 is provided on the inner wall of the cylinder 12, and the spiral groove 121 provides a spiral path for the water flow on the inner wall of the cylinder 12. The spiral ascending direction of the spiral groove 121 is opposite to the spiral direction of the spiral push piece 22, thereby preventing the spiral push piece 22 from being engaged incorrectly.

[0044] The ice breaker 4 includes an ice-breaking cone platform 42 and a connecting column 43 which are coaxially arranged and integrally connected. The minimum diameter of the ice-breaking cone platform 42 is the same as the diameter of the connecting column 43. The connecting column 43 vertically passes through the ice outlet head 3. The end of the connecting column 43 away from the ice-breaking cone platform 42 is threadedly connected to the screw 21. The ice-breaking cone platform 42 is located above the ice outlet head 3.

[0045] Reference Figure 2 and Figure 3 The lower part of the screw 21 is provided with a thrust ring and a support seat 24 for preventing the screw scraper 2 from moving downward. The thrust ring is coaxially arranged with the screw 21 and connected as a whole, and the thrust ring is located between the spiral push piece 22 and the drive seat 14. The support seat 24 is sleeved and fixedly connected to the outer wall of the screw 21 and abuts between the thrust ring and the drive seat 14.

[0046] A first flow channel 211 is provided at the center axis of the screw 21, and a water inlet hole is provided on the side wall of the screw 21, which can connect the first flow channel 211 with the inside of the cylinder 12. A second flow channel 41 is provided at the center axis of the ice breaker 4, and the second flow channel 41 is provided to the upper end surface of the ice-breaking cone 42, and the first flow channel 211 and the second flow channel 41 are connected to each other. A water outlet 431 is provided on the outer wall of the connecting column 43 protruding from the ice-discharging head 3, and the water outlet 431 is located between the ice-breaking cone 42 and the ice-discharging head 3 and is connected to the second flow channel 41.

[0047] Reference Figure 2 and Figure 4 The ice outlet head 3 is provided with a plurality of ice extrusion outlets 31 perpendicular to the end surface, and each ice extrusion outlet 31 is evenly circumferentially arranged on the ice outlet head 3. The ice extrusion outlets 31 are provided with an extrusion section 311 and a shaping section 312 from bottom to top, and the inner diameter at the position of the extrusion section 311 gradually decreases from bottom to top, and the inner diameter at the position of the shaping section 312 is the same as the minimum inner diameter of the extrusion section 311.

[0048] A notch 3111 is provided on one side of the ice outlet head 3 close to the sleeve 1. The notch 3111 is provided on the wall surface of the extrusion section 311 and is recessed toward one side of the shaping section 312. When ice debris is pushed to the position of the ice outlet head 3, it is difficult for the ice debris to enter the ice outlet. The notch 3111 can guide the ice debris, so that the ice debris can be smoothly guided and enter the extrusion section 311 and the shaping section 312 in turn, avoiding blockage caused by the ice debris in the ice outlet 31 and reducing ice debris residue.

[0049] The implementation principle of the evaporator of an ice-making machine in the embodiment of the present application is as follows: water flows into the cylinder 12 through the water pipe, and under the action of the refrigerant, the liquid water gradually freezes from the outside to the inside, and the ice-water mixture in the freezing process is pushed up by the screw scraper 2, and the solid ice residue in the ice-water mixture is squeezed and shaped by the ice-discharging head 3 to form an icicle. After the icicle is pushed out of the ice-discharging head 3, it abuts against the cone surface of the ice-breaking cone platform 42, and the effect of cutting the icicle is achieved due to the force of the lower part continuing to push up.

[0050] When the ice maker stops running, the ice-water mixture in the cylinder 12 is completely solidified and freezes the screw scraper 2. At this time, the water flows into the first flow channel 211 and the second flow channel 41 in sequence from the water inlet 212, and finally flows out from the water outlet 431 and falls onto the ice-discharging head 3. The water flow can first separate the contact surface between the ice cube and the ice-discharging head 3, and peel the ice cube from the ice-discharging head 3. Secondly, the water flow flows into the cylinder 12 through the spiral flow path provided by the spiral groove 121, which helps the ice column melt and provides space for the screw scraper 2 to rotate.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
