Description

Technical Field

[0001] The utility model relates to the technical field of ice making, in particular to an ice making component and an ice making device. Background Art

[0002] An ice maker is a mechanical device that uses heat pump technology to quickly freeze water into ice. Depending on the principle of the evaporator and the production method, the shapes of the ice cubes generated are also different. Among them, the icicles produced by the extrusion ice maker are the most popular.

[0003] Extrusion ice machines have been developed for many years, but the following problems still exist:

[0004] The first is the freezing problem. For example, when the ambient temperature is relatively low, the ice produced by the refrigeration system cannot be discharged in time, and accumulates in the ice-making chamber and freezes to the ice-squeezing screw. When the existing ice-making machine is frozen, the "ice-melting" time can reach 32 minutes.

[0005] The second is the problem of ice crushing. For example, when the ambient temperature is relatively high, the ice produced by the refrigeration system is discharged from the ice-making chamber without being fully squeezed, forming loose ice chips. Utility Model Content

[0006] In view of the shortcomings of the existing methods, the present application provides an ice-making assembly and an ice-making device. The technical solution provided by the embodiments of the present application brings at least the following beneficial effects: First, the refrigeration efficiency is maximized, and at the same time, the harmful resistance of the ice-discharging system is reduced to prevent the occurrence of freezing. Secondly, the temperature of the ice scraper is controlled by the temperature adjustment control unit, so that the temperature of the ice scraper is higher than the freezing point, thereby preventing ice chips from freezing between the ice scraper. Thirdly, through the control technology, the water for ice making is pre-cooled, so that the ice making process is minimally affected by the environment, thereby preventing the occurrence of crushed ice. In addition, through the skills of structural design, the axial force of the ice scraper is balanced on the mounting seat to prevent the drive device from being subjected to axial force, thereby simplifying the force state of the drive device and simplifying the structure of the drive device. There is no freezing in the embodiment of the present application. After it is "frozen" by human intervention, the ice melting time of this embodiment is only 12 minutes.

[0007] In view of the technical problems involved in the background technology, in the first aspect, the embodiment of the present application provides an ice-making assembly, including a cylinder, a mounting seat, an ice-squeezing member, an ice-scraping member, and a temperature control unit. The cylinder has an ice-making chamber inside, and the upper end of the cylinder serves as an ice-discharging end; the mounting seat is assembled at the lower end of the cylinder; the ice-scraping member is assembled in the ice-making chamber; the ice-scraping member includes a rotating shaft, a supporting structure arranged on the rotating shaft, and a receiving chamber extending along the axial direction of the rotating shaft; the ice-scraping member rotates relative to the cylinder under the drive of the driving device; the temperature control unit is assembled in the receiving chamber; the ice-squeezing member is assembled at the upper end of the cylinder; wherein the cross-sectional area of ​​the rotating shaft perpendicular to the axial direction of the rotating shaft gradually increases in the direction close to the mounting seat; the supporting structure is supported and connected to the mounting seat, and the axial force is avoided from being applied to the driving device by limiting the axial movement of the ice-scraping member.

In addition, if the detailed description of the known technology is unnecessary for the features of the present application shown, it will be omitted.

[0024] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a", "an", "said" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present application refers to the presence of the features, elements and / or components, but does not exclude the presence or addition of one or more other features, elements, components and / or groups thereof. The term "and / or" used herein includes all or any unit and all combinations of one or more associated listed items.

[0025] like Figure 1-4 As shown, the embodiment of the present application provides an ice-making assembly, which mainly includes a barrel 1, a mounting seat 2, an ice scraper 3, an ice squeezer 6 and a temperature control unit 4. The barrel 1 has an ice-making chamber 11 inside, and the upper end of the barrel 1 serves as an ice outlet end; the mounting seat 2 is mounted on the lower end of the barrel 1; the ice scraper 3 is mounted in the ice-making chamber 11; the ice scraper 3 includes a rotating shaft 31, a supporting structure 32 arranged on the rotating shaft 31, and a receiving chamber 33 extending axially along the rotating shaft 31; the ice scraper 3 rotates relative to the barrel 1 under the drive of the driving device; the temperature control unit 4 is mounted in the receiving chamber 33; the ice squeezer 6 is mounted on the upper end of the barrel 1; wherein, the cross-sectional area of ​​the rotating shaft 31 perpendicular to the axial direction of the rotating shaft 31 gradually increases in the direction close to the mounting seat 2; the supporting structure 32 is supported and connected to the mounting seat 2, and the axial movement of the ice scraper 3 is limited to avoid applying the axial force to the driving device.

[0026] In this embodiment, the cylinder 1 is a cylindrical structure. The cylinder 1 is vertically arranged on a horizontal plane, that is, the axis of the cylinder 1 is arranged in the vertical direction. The shell wall of the cylinder 1 is arranged to form a cylindrical ice-making chamber 11, and the top of the cylinder 1 is provided with an ice outlet connected to the ice-making chamber 11. The lower part of the cylinder 1 is provided with a water inlet end 16 connected to the ice-making chamber 11, and the water flowing into the ice-making chamber 11 through the water inlet end 16 is used to form an ice layer after cooling.

[0027] The ice scraper 3 is a columnar structure as a whole, and is vertically assembled in the ice making chamber 11. The ice scraper 3 can rotate relative to the cylinder 1. The horizontal cross section of the rotating shaft 31 gradually increases from top to bottom to form a structure with a small upper end and a large lower end. Optionally, the axial cross section of the rotating shaft 31 is an isosceles trapezoid. Optionally, the main body of the rotating shaft 31 is a conical structure, and the top and bottom ends of the cone are both flat.

[0028] A spiral scraper 37 surrounds the outer side of the rotating shaft 31, and the outer diameter of the spiral scraper 37 is close to the inner wall of the ice making chamber 11. In the ice making state, an ice layer is formed on the inner wall of the ice making chamber 11. The spiral scraper 37 rotates synchronously with the rotating shaft 31, and the outer edge of the spiral scraper 37 interferes with the ice layer to achieve the ice scraping action and obtain crushed ice. The crushed ice falls on the spiral scraper 37, and the accumulated crushed ice residue is squeezed toward the ice outlet along the spiral scraper 37.

[0029] The ice squeezing member 6 is arranged at the top end of the cylinder 1, and the ice squeezing member 6 can squeeze the crushed ice into ice cubes, so as to facilitate the formation of ice cubes.

[0030] like Figure 1 and 3 As shown, the ice scraper 3 has a receiving cavity 33 extending in the vertical direction. The receiving cavity 33 is coaxial with the rotating shaft 31 . A temperature adjustment component 4 is fixed in the receiving cavity 33 .

[0031] In some embodiments, the temperature adjustment unit 4 is a heating rod, and the heating rod is adapted to the accommodating cavity 33. The heating rod is controlled to heat up so as to control the temperature of the spiral scraper 37 to be higher than 0 degrees.

[0032] In some embodiments, the ice making assembly further includes a temperature controller, a rotating power supply component and a temperature measuring component. The controller outputs an appropriate current to heat the heating rod according to the actual temperature measured by the temperature measuring component. The temperature signal and the heating current are transmitted through the rotating power supply component.

[0033] The mounting seat 2 is mounted on the bottom of the barrel 1 and cooperates with the supporting structure 32 to support the ice scraper 3. The lower end of the ice scraper 3 is embedded in the mounting seat 2 and forms a stable support to limit the ice scraper 3 from moving in the axial direction close to the driving device.

[0034] The ice-making assembly provided in the embodiment of the present application has a support structure 32 that is supported and connected to the mounting seat 2 to limit the axial movement of the ice scraper 3, so that the axial force of the ice scraper 3 is balanced on the mounting seat 2, thereby preventing the driving device from being subjected to the axial force, simplifying the force state of the driving device, and further simplifying the structure of the driving device.

[0035] The rotating shaft 31, the spiral scraper 37 and the wall of the ice-making chamber 11 are arranged to form a spiral ice-receiving space, and the capacity of the ice-receiving space gradually increases in the direction close to the ice outlet, that is, the ice-receiving space gradually expands from bottom to top, providing sufficient space for the crushed ice near the ice outlet to gather. In this way, the ice outlet will not be affected by the increase in the diameter of the rotating shaft 31, and it is helpful to prevent the occurrence of freezing blockage.

[0036] By controlling the temperature adjustment unit 4, the temperature of the ice scraper 3 is always kept above the freezing point, thereby preventing the squeezed ice from freezing between the spiral scraper 37 and avoiding the occurrence of freezing blockage.

[0037] like Figure 1 and 3 As shown, as an optional embodiment, the ice scraper 3 further includes a sealing shaft 34 , which is coaxially connected to the rotating shaft 31 ; the supporting structure 32 is disposed at the connection between the sealing shaft 34 and the rotating shaft 31 .

[0038] Based on the above embodiments, in this embodiment, the sealing shaft 34 is connected to the large end of the rotating shaft 31. The shaft diameter of the sealing shaft 34 is smaller than the shaft diameter of the rotating shaft 31 to facilitate the installation of the mechanical sealing structure. The supporting structure 32 is located below the rotating shaft 31.

[0039] As an optional implementation, the support structure 32 is a step structure.

[0040] Based on the above embodiments, in this embodiment, the support structure 32 is an annular structure. The support structure 32 is radially protruding or recessed from the sealing shaft 34. Figure 3 FIG. 3 is a diagram showing that the support structure 32 is recessed in the sealing shaft 34 .

[0041] like Figure 1 As shown, as an optional embodiment, the ice-making assembly also includes a seal 5, which is fixed in the ice-making chamber 11, and the seal 5 is sleeved on the outside of the sealing shaft 34 and is sealed with the sealing shaft 34; the seal 5 is also supported and connected with the big end 30 of the rotating shaft 31.

[0042] Based on the above embodiments, in this embodiment, the seal 5 is an annular structure and is disposed below the rotating shaft 31, and the inner side of the seal 5 is sealed and connected to the outer side of the sealing shaft 34. The big end 30 of the rotating shaft 31 is the bottom end of the rotating shaft 31, and the top surface of the seal 5 is supported on the big end 30 of the rotating shaft 31 to achieve supporting mechanical sealing. Optionally, the top surface of the seal 5 and the bottom surface of the big end 30 of the rotating shaft 31 are both horizontal surfaces.

[0043] In a specific embodiment, the sealing member 5 includes a first ring member and a second ring member arranged from top to bottom, and the sealing shaft 34 extends into the first ring member and the second ring member. The top of the first ring member is supported on the rotating shaft 31, and the first ring member is a moving ring. The second ring member is relatively fixed to the cylinder 1, and the second ring member is a fixed ring. There is a sealing surface between the first ring member and the second ring member, and the sealing surface has a very small friction coefficient. The first ring member includes a spring, which is surrounded by the outer side of the sealing shaft 34. When the first ring member is in the rotation stage of the ice scraper 3, the spring generates an axial force to limit the movement of the first ring member, ensures that relative friction is generated between the first ring member and the second ring member, and ensures that the water does not flow out through the water film between the two, thereby achieving sealing between the two and ensuring that water does not leak from the bottom of the ice scraper 3.

[0044] In some embodiments, the bottom of the sealing member 5 is fixedly connected to the mounting base 2 to form a stable support.

[0045] like Figure 1 and 2 As shown, as an optional embodiment, the cavity wall of the ice making cavity 11 has a spiral refrigerant channel 12, which is formed by clamping and surrounds the outer side of the rotating shaft 31. The refrigerant channel 12 is provided with a refrigerant inlet end 13 and a refrigerant outlet end 14 for communicating with the outside.

[0046] Based on the above embodiments, in this embodiment, a refrigerant channel 12 is provided in the wall of the ice making chamber 11. The outer wall of the cylinder 1 is recessed to form a groove structure, and the shell is sleeved on the outer side of the groove structure to form an interlayer, that is, the refrigerant channel 12 is formed.

[0047] The refrigerant outlet 14 is higher than the refrigerant inlet 13, and the refrigerant inlet 13 is higher than the water inlet 16. The liquid refrigerant flows through the refrigerant inlet 13 into the refrigerant channel 12, flows from bottom to top along the refrigerant channel 12, absorbs the heat in the ice-making chamber 11, changes from liquid to gas, and finally flows out from the refrigerant outlet 14.

[0048] The end face shape of the vertical section of the refrigerant channel 12 is a trapezoid. The vertical cross-sectional shape of the refrigerant channel 12 is a shape obtained through thermal engineering calculations to maximize the contact area with the refrigerant and minimize the total thermal resistance. The short side of the aforementioned trapezoid is close to the ice-making chamber 11. The refrigerant channel 12 can ensure the orderly flow of the refrigerant and maximize the heat transfer area between the refrigerant and the wall of the ice-making chamber 11, thereby achieving stable ice making.

[0049] In some embodiments, the refrigerant channel 12 is an I-shaped annular groove.

[0050] As an optional embodiment, the ice squeezing member 6 has multiple ice squeezing channels 61, all of which are connected to the ice making chamber 11, each of which includes an ice inlet 62, all of which are distributed circumferentially, and the edges of adjacent ice inlets 62 are close to each other to reduce ice obstruction.

[0051] Based on the above embodiments, in this embodiment, the ice squeezing member 6 is a smooth transitional irregular body, which is cylindrical near the ice outlet end, and the resistance of the residual plane to the flow of the ice layer is minimized in the ice inlet section. This prevents the crushed ice from being squeezed into ice cubes on the residual plane. The ice inlet 62 of the ice squeezing member 6 is at the bottom, and the ice outlet is at the top. The ice inlet 62 of the ice squeezing member 6 is connected to the ice outlet of the cylinder 1. Multiple ice squeezing channels 61 are evenly arranged around the axis of the rotating shaft 31.

[0052] In some embodiments, the bottom surface of the ice squeezer 6 is a plane. The horizontal cross-section of the ice inlet 62 is a trapezoid, and the short sides of all ice inlet 62 trapezoids are inward and the long sides are outward. The waists of adjacent trapezoids are close to each other, which increases the proportion of the flow area of ​​the ice inlet 62 on the bottom surface of the ice squeezer 6, reduces the generation of plane ice resistance, and thus reduces the probability of freezing blockage.

[0053] The vertical section of the ice squeezing channel 61 is a trumpet-shaped ice squeezing section, with the large mouth of the ice squeezing section at the bottom, which can increase the amount of crushed ice entering the ice squeezing channel 61, and after a large amount of crushed ice enters, the transverse section of the ice squeezing section changes from large to small, that is, the flow area changes from large to small, which is conducive to squeezing the crushed ice to form ice cubes and improve the quality of ice output. Among them, the transverse section of the ice squeezing section can be circular, rectangular or other shapes. If the ice squeezing channel 61 is not designed properly, the crushed ice may be directly discharged due to insufficient squeezing, or it may be frozen due to excessive squeezing.

[0054] The ice making assembly further includes an ice folding member 7 disposed above the ice squeezing member 6, the outer side of the ice folding member 7 being an ice folding slope, which is used to break the ice cubes discharged from the ice squeezing channel 61. The ice folding member 7 can be detachably mounted with the ice squeezing member 6, or can be an integrally formed structure with the ice squeezing member 6, which is not specifically limited in the present application.

[0055] In some embodiments, the ice squeezing member 6 has a vertically extending, centrally disposed limiting hole 63, and a plurality of ice squeezing channels 61 surround the outer side of the limiting hole 63. A cylindrical upper bearing 64 is disposed on the inner wall of the limiting hole 63.

[0056] The ice scraper 3 also includes a limiting shaft 38, which is coaxially connected to the rotating shaft 31. The limiting shaft 38 is arranged on the side of the rotating shaft 31 opposite to the sealing shaft 34, that is, the limiting shaft 38 is arranged above the rotating shaft 31. The limiting shaft 38 extends into the limiting hole 63 of the ice squeezer 6, and the upper bearing 64 is sleeved on the outer side of the limiting shaft 38. The upper bearing 64 provides radial support for the limiting shaft 38 to keep the axis of the rotating shaft 31 vertical and avoid the axis of the rotating shaft 31 from deviating. The top of the rotating shaft 31 abuts against the bottom of the upper bearing 64 to limit the upward movement of the ice scraper 3.

[0057] As an optional embodiment, the ice scraper 3 further includes a guide shaft 36 , which is coaxially connected to the sealing shaft 34 . The guide shaft 36 is arranged on a side of the sealing shaft 34 opposite to the rotating shaft 31 to prevent the rotating shaft 31 from tilting and moving.

[0058] Based on the above embodiments, in this embodiment, the guide shaft 36 is coaxially connected to the sealing shaft 34 and is located below the sealing shaft 34. The shaft diameter of the guide shaft 36 is smaller than the shaft diameter of the sealing shaft 34, and a support structure 32 is formed at the connection between the sealing shaft 34 and the guide shaft 36;

[0059] The ice scraper 3 further comprises a power input shaft 39, which is used to connect with the driving device. The power input shaft 39 is coaxially connected with the guide shaft 36, and the power input shaft 39 is arranged on the side of the guide shaft 36 opposite to the sealing shaft 34, that is, the power input shaft 39 is arranged below the guide shaft 36.

[0060] The mounting seat 2 includes a base 21, the top of which is supported and connected to the aforementioned sealing member 5. The middle of the mounting seat 2 has a through hole extending in the vertical direction, and a lower bearing 22 is arranged in contact with the inner wall of the through hole. The guide shaft 36 of the ice scraper 3 extends into the lower bearing 22, and the power input shaft 39 extends out of the through hole. The lower bearing 22 is sleeved on the outside of the guide shaft 36, which can provide radial support for the guide shaft 36, keep the axis of the rotating shaft 31 vertical, and avoid the axis of the rotating shaft 31 from shifting; the top of the lower bearing 22 is supported and connected to the support structure 32, which can limit the downward movement of the ice scraper 3. Among them, the upper bearing 64 and the lower bearing 22 are coaxial.

[0061] In addition, it should be noted that the main body of the rotating shaft 31 is a conical structure in order to obtain a step structure without reducing the shaft diameter of the power input shaft 39 .

[0062] like Figure 1 and 3 As shown, as an optional embodiment, the ice scraper 3 has an ice-melting medium channel 35 communicating with the ice-making chamber 11 .

[0063] Based on the above-mentioned embodiment, in this embodiment, the ice-melting medium channel 35 passes through the above-mentioned limit shaft 38, the outlet end of the ice-melting medium channel 35 is located at the top of the limit shaft 38, and the inlet end of the ice-melting medium channel 35 is located at the upper part of the rotating shaft 31. In the normal ice-making stage, the ice-melting medium channel 35 is not used. After freezing and blockage occur, water enters the ice-making chamber 11 under the drive of the pump, and the continuously flowing water plays a role in quickly melting ice, effectively solving the freezing and blockage, and then the water is discharged from the ice-melting medium channel 35.

[0064] like Figure 1 and 2 As shown, as an optional embodiment, a spiral groove 15 is provided on the inner side of the cavity wall of the ice-making cavity 11 and is recessed in the cavity wall of the ice-making cavity 11 . The spiral groove 15 is provided around the outer side of the rotating shaft 31 .

[0065] Based on the above embodiments, in this embodiment, the depth of the spiral groove 15 is 0.5 mm and the width is 1.5 mm. The spiral direction of the spiral groove 15 is different from the spiral direction of the spiral scraper 37. When the spiral scraper 37 scrapes the ice layer on the inner wall of the ice making chamber 11, the spiral scraper 37 and the spiral groove 15 work together to make the ice generate a force moving toward the ice squeezing member 6 at the moment of being scraped off, thereby preventing the crushed ice from rotating with the ice scraping member 3 to form a freezing blockage.

[0066] Based on the same inventive concept, an embodiment of the present application provides an ice-making device, which includes the ice-making assembly of any one of the aforementioned embodiments.

[0067] Based on the above embodiments, in this embodiment, the ice-making device further includes a driving device, a water tank, a cooling system and an ice storage container. The driving device may be a reducer, and the output shaft of the driving device is connected to the ice scraper 3 of the ice-making assembly. The water tank is connected to the water inlet end 16 of the ice-making assembly; the cooling system is connected to the refrigerant inlet end 13 and the refrigerant outlet end 14 of the ice-making assembly. The ice storage container is used to receive the discharged ice cubes.

[0068] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0069] First, the refrigeration efficiency is maximized, and at the same time, the harmful resistance of the ice-discharging system is reduced to prevent freezing. Secondly, the temperature of the ice scraper 3 is controlled by the temperature adjustment unit 4, so that the temperature of the ice scraper 3 is higher than the freezing point, thereby preventing ice chips from freezing between the ice scraper 3. Thirdly, through control technology, the water used for ice making is pre-cooled to minimize the impact of the environment on the ice making process, thereby preventing the occurrence of crushed ice. In addition, through structural design techniques, the axial force of the ice scraper 3 is balanced on the mounting seat 2 to prevent the drive device from being subjected to axial force, thereby simplifying the force state of the drive device and simplifying the structure of the drive device. There was no freezing in the embodiment of the present application. After it was "frozen" by human intervention, the ice melting time of this embodiment was only 12 minutes.
