Description

Technical Field

[0001] The invention belongs to the technical field of ice making equipment, and in particular relates to a double-cavity transparent ice mold of an ice making machine. Background Art

[0002] Most ice purchased in the market is white. This is because a certain amount of air is dissolved in the water. During the freezing process, the still water is rapidly frozen, causing its density to decrease. This allows the air to precipitate, but the trapped air cannot escape, leaving the ice. This causes the ice to appear milky white due to the refraction of light. With the development of ice-making technology, the demand for specifically shaped ice and transparent ice has gradually increased, leading to the development of various transparent ice-making machines and auxiliary devices.

[0003] For example, in a prior application with publication number CN118960279A, the applicant proposed a stirring mechanism for an ice maker, comprising a driving gear and at least one driven gear provided on the ice maker, and a first driving device for driving the driving gear to rotate, wherein the driving gear is engaged with the driven gear, and the driven gear is provided with at least one driving magnetic element; a stirring component is provided in an ice-making chamber of the ice maker, and the stirring component is provided with at least one driven magnetic element that cooperates with the driving magnetic element... The stirring mechanism stirs the liquid by driving the stirring component inside the ice-making chamber, so that bubbles in the liquid can be discharged in a timely manner, thereby producing transparent ice cubes.

[0004] For example, Chinese invention patent publication number CN120043292A provides an ice-making control system and an ice-making machine, comprising: an ice-making container having an upwardly opening storage chamber, a lid for opening or closing the storage chamber opening, the storage chamber having an ice-making height line located below the opening, a refrigeration module in contact with the outer bottom of the ice-making container, and a stirring assembly and a detection unit located above the ice-making height line in the ice-making container or the lid. The detection unit and the refrigeration module are both electrically connected to a control module. In this solution, as water in the storage chamber gradually cools and solidifies into ice cubes from bottom to top, the stirring assembly stirs the water above the ice-making height line to expel air bubbles from the water, making the ice cubes crystal clear. The detection unit detects whether the height of the ice cubes has reached the ice-making height line. When the ice cubes reach the ice-making height line, the control module controls the refrigeration module to stop operating, thereby producing ice cubes with high dimensional accuracy.

[0005] However, the above solutions all use built-in stirring components to directly stir the liquid in the ice-making chamber, which has at least the following shortcomings: 1. The stirring head has a high risk of freezing, or the detection accuracy of the freezing degree must be high; 2. It is difficult to produce relatively complete ice cubes of special shapes (such as ice balls).

[0006] Therefore, there is an urgent need for a transparent ice preparation solution that is low in cost and can take into account equipment safety, ice shape integrity and ice transparency. Summary of the Invention

[0007] The object of the present invention is to provide a double-cavity transparent ice mold for an ice maker, so as to partially alleviate or solve the above-mentioned problems and achieve safer, more efficient and high-quality transparent ice production.

[0008] In order to solve the above-mentioned technical problems, the present invention specifically adopts the following technical solutions: A double-cavity transparent ice mold for an ice maker, comprising: a bracket, a waterproof shell, a stirring mechanism and a mold; The mold is detachably mounted on the bracket, an ice-making chamber is provided inside the mold, a solution exchange port is provided at the top of the ice-making chamber, the waterproof housing is mounted on the bracket, at least a portion of the waterproof housing protrudes upward to form a stirring chamber with an opening at the bottom, and the stirring chamber is connected to the ice-making chamber via the solution exchange port; The stirring mechanism includes a stirring motor and a stirring component, wherein the stirring motor is mounted on the upper surface of the waterproof housing, an output shaft of the stirring motor passes through the waterproof housing and extends into the stirring chamber, and the stirring component is arranged at the output end of the output shaft; When the stirring motor is driven to rotate, the output shaft drives the stirring component to rotate, thereby driving the liquid in the stirring chamber to flow and exchange with the liquid in the ice-making chamber, so that the bubbles in the ice-making chamber can escape from the solution exchange port into the stirring chamber.

[0009] As an improvement, the height of the top of the stirring chamber gradually increases from the first end to the second end and then remains unchanged, forming in sequence a bubble guide area with a certain angle to the horizontal plane and a bubble buffer area parallel to the horizontal plane. The bubbles inside the stirring chamber can move along the bubble guide area to the second end of the stirring chamber and enter the bubble buffer area.

[0010] As an improvement, the mold includes a first region and a second region sequentially arranged from top to bottom, and the thermal conductivity of the first region is smaller than the thermal conductivity of the second region.

[0011] As an improvement, a reflux slope is provided on the top of the mold along the circumference of the solution exchange port, and the reflux slope gradually increases in height from the side close to the solution exchange port to the direction away from the solution exchange port to form a solution guide area with an opening facing upward.

[0012] As an improvement, an exhaust port and a liquid outlet are provided on the top of the waterproof housing, and the exhaust port and the liquid outlet are used to connect the stirring chamber with the external environment.

[0013] As an improvement, the inner wall junctions between the bubble guiding area and the bubble buffer area and other parts of the waterproof housing are connected by a chamfered structure.

[0014] As an improvement, the stirring component includes a plurality of stirring blades, the bottom of the stirring blades gradually increases in height from the inside to the outside to form a stirring slope, and the acute angle between the stirring slope and the horizontal plane is in the range of 8°-12°.

[0015] As an improvement, the acute angle between the bubble guiding area and the horizontal plane is in the range of 8°-10°.

[0016] As an improvement, the top of the stirring chamber is recessed downward to form an installation chamber, the stirring motor is arranged in the installation chamber, and the bubble guide area and the bubble buffer area are arranged around the installation chamber to form an annular guide path.

[0017] As an improvement, the height of the stirring chamber is 15 mm-23 mm.

[0018] The principles and beneficial technical effects of the present invention are: Completely different from the built-in stirring technology in the existing technology, this application proposes a diversion-type dual-cavity partitioned transparent ice production solution. Through an external stirring component, combined with the diversion effect of the bubble guide area and the reflux slope, there is no need to monitor the ice making progress in real time. It can also quickly stir across areas while avoiding the problems of untimely bubble discharge and large-scale bubble reflux, thereby achieving safer, more efficient and high-quality transparent ice (especially "complete" ball ice) production.

[0019] The transparent ice mold with the above structure operates as follows: During ice making, the transparent ice mold is mounted on the refrigeration plate of the ice maker, allowing the heat-conducting layer at the bottom of the mold to contact the refrigeration plate for heat exchange. Simultaneously, the stirring motor is activated to drive the stirring element to rotate, thereby simultaneously stirring the liquid in the partitioned stirring chamber and ice-making chamber while cooling the ice. This helps to expel bubbles from the ice-making chamber. After entering the stirring chamber, bubbles in the ice-making chamber are collected along the bubble guide area into the bubble buffer zone, preventing them from dispersing and redissolving in the liquid during the stirring process and flowing back into the ice-making chamber. Simultaneously, during the reflux process, the liquid flows smoothly back into the ice-making chamber along the reflux slope. This not only improves the liquid's reflux efficiency to a certain extent, but also further prevents the liquid from excessively colliding with the inner wall of the ice-making chamber during the stirring process, which could lead to an increase in bubble dissolution. In other words, the above process is actually a "gas-liquid diversion" process, which can simultaneously ensure stirring efficiency and reduce bubble backflow. After ice making is completed, the liquid exchange path between the ice making chamber and the stirring chamber is blocked, and the two no longer exchange heat. At this time, the stirring action only occurs in the stirring chamber, which can effectively avoid the problem of the stirring parts being solidified or the motor being damaged due to continuous refrigeration.

For example, "connected" can mean fixed, removable, or integral; it can mean mechanical, direct, or indirect through an intermediary, or it can mean internal communication between two components.

[0026] Example 1 This embodiment is basically as shown in the attached Figure 1-5 As shown: The present invention provides a double-cavity transparent ice mold for an ice maker, comprising a bracket 7, a waterproof shell 10, a stirring mechanism and a mold 33.

[0027] The mold 33 is detachably mounted on the bracket 7 , an ice-making chamber 26 is disposed inside the mold 33 , a solution exchange port 30 is disposed at the top of the ice-making chamber 26 , and the waterproof housing 10 is disposed on the bracket 7 , at least a portion of the waterproof housing 10 protrudes upward to form a stirring chamber 27 with a bottom opening, and the stirring chamber 27 is connected to the ice-making chamber 26 via the solution exchange port 30 .

[0028] The stirring mechanism includes a stirring motor 4 and a stirring component 12. The stirring motor 4 is installed on the upper surface of the waterproof shell 10. The output shaft of the stirring motor 4 passes through the waterproof shell 10 and extends into the stirring chamber 27. The stirring component 12 is arranged at the output end of the output shaft.

[0029] When the stirring motor 4 is driven to rotate, the output shaft drives the stirring component 12 to rotate, thereby driving the liquid in the stirring chamber 27 to flow and exchange with the liquid in the ice-making chamber 26, so that the bubbles in the ice-making chamber 26 can escape from the solution exchange port 30 into the stirring chamber 27.

[0030] In some embodiments, a slide groove 28 is provided on the bracket 7 along the width direction or the length direction. Correspondingly, a slider 29 is provided on the mold 33. The mold 33 is slidably set in the slide groove 28 through the slider 29. When the mold 33 is pulled, the slider 29 slides in the slide groove 28 and slides out of the slide groove 28, and the mold 33 can be quickly removed from the bracket 7.

[0031] In some embodiments, the top of the waterproof housing 10 is provided with an exhaust port 5 (preferably, the exhaust port is provided in the bubble buffer zone), and / or a liquid outlet (see Figure 3 The drain pipe 6 in the mixing chamber 27 is provided. The exhaust port and / or the liquid outlet are used to connect the mixing chamber 27 to the external environment. The mold 33 is provided with a water inlet (not shown in the figure). When water is poured into the mold, once the mold is filled, the water enters the mixing chamber 27 along the solution exchange port 30. When the mixing chamber 27 is also filled, the liquid can be discharged through the liquid outlet. During the ice-making process, bubbles in the water gradually flow from the ice-making chamber 26 to the mixing chamber 27 under the stirring action of the stirring member 12, and then are discharged from the exhaust port 5. At the same time, any excess liquid during the freezing process can also be discharged from the liquid outlet.

[0032] In summary, the present invention comprehensively provides a dual-cavity quick-detachable transparent ice-making mold with an external stirring mechanism. When ice making is required, the mold is quickly installed on the bracket. During the ice-making process, the stirring component performs indirect stirring in an independent stirring chamber. It is easy to assemble and disassemble, and can prevent the low space utilization rate in the ice-making chamber (especially the problem of incomplete shape during the production of ball ice), as well as the problem that the stirring component is easy to freeze or has high requirements for monitoring the degree of freezing, thereby realizing efficient and high-quality transparent ice production.

[0033] In some embodiments, the height of the top of the stirring chamber 27 gradually increases from the first end to the second end and then remains unchanged, sequentially forming a bubble guide area 23 with a certain angle to the horizontal plane and a bubble buffer area 24 parallel to the horizontal plane. The bubbles inside the stirring chamber 27 can move along the bubble guide area 23 to the second end of the stirring chamber 27 and enter the bubble buffer area 24. The first end to the second end of the stirring chamber 27 is referred to as Figure 4 In the direction a indicated by the middle arrow, that is, when viewed from the front, the top of the stirring chamber 27 is a slope inclined upward to the right. After entering the stirring chamber 27, the bubbles can gradually float upward and adhere to the slope. The bubbles on the slope will move along the slope to the top (i.e., the second end) and finally be gathered in the bubble buffer zone 24 to prevent the bubbles from being distributed everywhere and being brought back into the ice-making chamber 27 during the stirring process.

[0034] In some embodiments, the acute angle between the bubble guiding area and the horizontal plane is in the range of 8°-10° (preferably 8°, see Figure 2 α in ), that is, the acute angle between the slope and the horizontal plane is in the range of 8°-10°.

[0035] In some embodiments, a reflux slope 25 is provided at the top of the mold 33 along the circumference of the solution exchange port 30. The reflux slope 25 gradually increases in height from the side closest to the solution exchange port 30 toward the side away from the solution exchange port 30, thereby forming a solution guide area 31 with an upward opening. In other words, the inner diameter of the solution exchange port 30 gradually increases from bottom to top to form the solution guide area 31, thereby better connecting with the stirring chamber 27.

[0036] In some embodiments, the stirring member 12 includes a plurality of stirring blades. The bottom of the stirring blades gradually increases in height from the inside to the outside (i.e., from the end closest to the output shaft to the end farther from the output shaft), forming a stirring slope 34. The acute angle between the stirring slope 34 and the horizontal plane is in the range of 8°-12° (preferably 10°). In some embodiments, the stirring slope 34 is parallel to the reflux slope 25.

[0037] In some embodiments, the inner wall interfaces between the bubble guide area 23 and the bubble buffer area 24 and the rest of the waterproof housing 10 are connected by chamfers. Alternatively, the edges of the bubble guide area 23 and the bubble buffer area 24 are chamfered. That is, the cross-sections of the bubble guide area 23, the bubble buffer area 24, and the rest of the waterproof housing 10 are all arc-shaped. This means that the present application provides a collision-resistant, diverting stirring chamber that diverts bubbles and liquid while preventing further bubbles from forming in the first place.

[0038] In some embodiments, the waterproof housing 10 is integrally formed with the bracket 7. The ice-making chamber 26 is semi-enclosed by the inner wall of the waterproof housing 10 and the top of the mold 33, leaving only the solution exchange port 30 and the exhaust / drain port.

[0039] In some embodiments, the top of the stirring chamber 27 is recessed downward (i.e., toward the direction of the mold) to form an installation cavity 37, the stirring motor 4 is disposed in the installation cavity 37, and the bubble guide area 23 and the bubble buffer area 24 are disposed around the installation cavity 37 to form an annular guide path.

[0040] The height difference between the first end and the second end of the top of the stirring chamber 27 is 10 mm (see Figure 2 The H in the figure, i.e., the height difference between the lowest point of the bubble buffer zone and the lowest point of the bubble guide zone, is 10mm. The height of the stirring chamber (i.e., the distance from the bubble buffer zone to the top of the mold) is 15mm-23mm. In other words, this application provides a split ice-making mold for rapid ice production. By limiting the height (or volume) of the stirring chamber, the heat carried away by the liquid inside is reduced. At the same time, by coordinating the inclined stirring and reflux slopes, the mold can increase space utilization while ensuring stirring efficiency, thereby improving ice-making efficiency.

[0041] In some embodiments, a first seal 11 is provided at the connection between the stirring motor 4 and the waterproof housing 10, and a second seal 13 is also provided circumferentially at the portion where the mold 33 contacts the bracket 7 to improve the sealing of the stirring chamber 27. Both the first seal 11 and the second seal 13 can be sealing rings.

[0042] In other words, the present application actually provides a diversion-type dual-cavity partitioned transparent ice production solution. During the ice-making process, by performing "gas-liquid diversion" on the gas and liquid, while ensuring that the liquid can be quickly exchanged across regions, the bubbles can be discharged in time, thereby avoiding the problem of bubble backflow, thereby achieving safer, more efficient and high-quality transparent ice (especially "complete" ball ice) production.

[0043] In some embodiments, the mold 33 includes a first region and a second region sequentially arranged from top to bottom, and the thermal conductivity of the first region is smaller than the thermal conductivity of the second region.

[0044] In some specific embodiments, the mold 33 includes an upper mold 8 and a lower mold 9. A second seal 13 is provided at the connection between the upper mold 8 and the lower mold 9. The first region is provided in the upper half of the upper mold 8, and the second region includes the lower half of the upper mold 8 and the entire lower mold 9. In other words, a first heat-conducting layer 19 and a second heat-conducting layer 20 are provided in sequence from top to bottom within the upper mold 8, and a third heat-conducting layer 21 is provided within the lower mold 9. The thermal conductivity of the first heat-conducting layer 19 is lower than that of the second heat-conducting layer 20 and the third heat-conducting layer 21. Of course, the thermal conductivity of the second heat-conducting layer 20 and the third heat-conducting layer 21 can be the same or different. The first heat-conducting layer 19 is located in the first region, and the second heat-conducting layer 20 and the third heat-conducting layer 21 are located in the second region. While ensuring cooling efficiency, the problem of excessively low temperatures at the solution exchange port causing the liquid in the solution exchange port and the stirring chamber to freeze can be avoided.

[0045] In some embodiments, an isolation region 32 is provided between the reflow slope 25 and the first heat conducting layer 19 , that is, the reflow slope 25 is not in direct contact with the first heat conducting layer 19 , or the reflow slope 25 is only partially in contact with the first heat conducting layer 19 .

[0046] In some specific embodiments, the mold 33 also includes an insulation shell, which includes a first shell 14 and a second shell 15 corresponding to the upper mold, and the first shell 14 and the second shell 15 are enclosed outside the upper mold and form a first insulation cavity 35, and the return slope 25 is arranged on the top of the first shell 14; the insulation shell also includes a third shell 16 and a fourth shell 17 corresponding to the lower mold, and the third shell 16 and the fourth shell 17 are enclosed outside the lower mold and form a second insulation cavity 36.

[0047] In some embodiments, the isolation area 32 is communicated with the first heat preservation chamber 35 .

[0048] In some embodiments, a heating film 18 is provided on the first heat-conducting layer 19 and the second heat-conducting layer 20 of the upper mold 8 , so that the ice cubes in the upper mold 8 are heated and demolded when taking ice.

[0049] In summary, the present application also provides a restrictive zoned refrigeration and ice protection mechanism. First, the present device divides the heat-conducting layer in the ice-making chamber into zones according to the thermal conductivity. While ensuring the refrigeration efficiency, it will not cause the temperature at the solution exchange port at the top of the ice-making chamber to be too low, causing the refrigeration effect to spread to the stirring chamber. Furthermore, the first heat-conducting layer on the reflux slope and the top of the upper mold is zoned and isolated, which can effectively prevent the temperature of the first heat-conducting layer from being transferred to the reflux slope, thereby causing the stirring chamber to be continuously refrigerated and frozen.

[0050] Example 2 This embodiment also provides an ice making machine, which is applied to the transparent ice mold in Example 1. The ice making machine includes a base, a lifting rod and a lifting mechanism. A refrigeration plate is provided on the base. The bracket of the transparent ice mold is slidably provided on the lifting rod. The lifting mechanism is used to drive the transparent ice mold to move up and down on the lifting rod. When the mold is slidably installed on the bracket, the ice drives the bracket downward through the lifting mechanism, so that the heat-conducting layer at the bottom of the mold contacts the refrigeration plate, and ice making can be carried out. When ice making is completed, the bracket is driven upward by the lifting mechanism to separate the mold from the refrigeration plate, and then the mold is removed from the bracket to take out the transparent ice cubes.

[0051] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0052] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
