The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the disclosure and together with the description, serve to explain the principles of the disclosure. It will be apparent to those of ordinary skill in the art that the drawings in the following description are merely examples of the disclosure and that other drawings may be derived from them without undue effort. In the drawings:
fig. 1 is a schematic view of an ice making apparatus provided in some embodiments of the present disclosure;
FIG. 2 is a schematic diagram of an ice making apparatus according to another view angle provided by some embodiments of the present disclosure; and

Detailed Description
For the purpose of promoting an understanding of the principles and advantages of the disclosure, reference will now be made in detail to the drawings, in which it is apparent that the embodiments described are only some, but not all embodiments of the disclosure. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.
It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a product or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such product or apparatus. Without further limitation, an element defined by the phrase "comprising" does not exclude the presence of other like elements in a commodity or device comprising such element.
In the related art, commercial ice making machines are large in size and cannot be used for home use, and heat generated in the ice making process is large, so that water cooling and heat dissipation are mostly needed. The bullet ice maker or the granular ice maker has low ice output per unit time and low speed. In particular, the limited number of ice molds for bullet ice makers results in low yields, and the limited water refrigeration mode of particle ice makers (e.g., the space between the screw and the sleeve is used to make ice chips) results in low yields. In addition, the size and/or hardness of ice cubes produced by an associated ice maker is generally not adjustable to the needs of the user.
To overcome the drawbacks in the related art, the present disclosure provides an ice making apparatus including: an ice dust preparation assembly configured to prepare raw water into ice dust; and an ice pressing assembly configured to receive ice dust and make the ice dust into ice cubes, the ice pressing assembly comprising: the ice pressing mold is provided with at least one mold unit, and the at least one mold unit is configured to be sequentially and circularly switched among a filling station, an ice pressing station and an ice removing station; the ice pressing push rod corresponds to the ice pressing station and is configured to push ice scraps in a die unit of the ice pressing station to press ice blocks; and an ice-removing push rod corresponding to the ice-removing station and configured to push ice cubes in a mold unit of the ice-removing station to be separated from the mold unit. The preparation rate of the ice chip raw materials in unit time is improved by arranging the independent ice chip preparation assembly, and the ice chip is made into ice cubes in a pushing mode by matching the ice pressing push rod with the die unit in the ice pressing die, so that the ice making rate of the granular ice is improved. Unlike the formation of ice dust on the inner wall of the screw sleeve of the screw ice making device in the related art, in some embodiments of the present disclosure, ice dust is formed on the outer wall of the element of the ice dust preparation assembly, which makes full use of the characteristic that the outer wall surface is large in size, increases the contact area between the refrigeration surface and the raw material water, and improves the heat exchange efficiency, thereby significantly improving the preparation efficiency of ice dust, and finally solving the problem of slow supply of ice dust raw material when making ice with granular ice in the related art.
Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.
Fig. 1 is a schematic structural view of an ice making apparatus according to some embodiments of the present disclosure, and fig. 2 is a schematic structural view of an ice making apparatus according to another view angle of some embodiments of the present disclosure. Fig. 3 is a schematic structural view of an ice pressing assembly according to some embodiments of the present disclosure.
As shown in fig. 1 to 3, some embodiments of the present disclosure provide an ice making apparatus 100, for example, a compression molding type ice making apparatus, the ice making apparatus 100 including an ice dust preparation assembly 10 and an ice pressing assembly 20. Wherein the ice chip preparation assembly 10 is configured to make raw water into ice chips and the ice pressing assembly 20 is configured to make the ice chips into ice cubes. Specifically, the ice pressing assembly 20 presses the ice dust into granular ice, for example, by pressing.
As shown in fig. 1 to 3, the ice pressing assembly 20 includes an ice pressing mold 21, an ice pressing push rod 22, and an ice removing push rod 23. The ice pressing mold 21 has at least one mold unit 211, and the number of the mold units 211 may be 1 or more. Each of the mold units 211 is configured to be sequentially cyclically switched among the filling station a, the ice pressing station B, and the ice removing station C. The mold unit 211 loads ice dust at the filling station a; at the ice pressing station, the ice dust in the mold unit 211 is pressed into ice pieces; at the ice removing station C, the ice cubes pressed in the mold unit 211 are separated from the mold unit 211. For each of the mold units 211, it passes through the filling station a, the ice pressing station B, and the ice removing station C in sequence during the ice making process, and is cycled back and forth. The mold unit 211 sequentially passes through the filling station a, the ice pressing station B, and the ice removing station C in each cycle, completing the steps of loading the ice chips, pressing the ice cubes, and removing the ice cubes.
The ice pressing push rod 22 corresponds to the ice pressing station B, and applies a pushing force in a vertical direction, for example. The ice pressing push lever 22 is configured to push the ice dust located in the die unit 211 of the ice pressing station B to press ice cubes, i.e., granular ice. For example, the ice pressing push rod 22 may be moved toward the ice pressing mold 21 in a vertical direction to press the ice chips located in the mold unit 211 of the ice pressing station B to be pressed into ice cubes, and after the ice pressing operation is finished, the ice pressing push rod 22 may be moved away from the ice pressing mold 21 in a vertical direction to retract to a non-pressing position, and the mold unit 211 having completed the ice pressing operation may be switched to the ice removing station C to perform the ice removing operation.
The de-icing push rod 23 corresponds to the de-icing station C, for example, pushing force is applied in a vertical direction, and the de-icing push rod 23 is configured to push ice cubes located in the die unit 211 of the de-icing station C out of the die unit 211 of the de-icing station C. For example, the ice-removing push rod 23 may be moved toward the ice-pressing mold 21 in the vertical direction to push ice cubes located in the mold unit 211 of the ice-removing station C to be separated from the mold unit 211 located in the ice-removing station C, and after the ice-removing operation is finished, the ice-removing push rod 23 may be moved away from the ice-pressing mold 21 in the vertical direction to be retracted to a non-pushing position, and the mold unit 211 having completed the ice-removing operation may be switched to the filling station a to perform the ice chip filling operation, and the next ice-making cycle is entered.
In some embodiments, as shown in fig. 1 to 3, the ice pressing mold 21 includes a rotating mold plate 212 and a fixed mold plate 213.
A rotary die plate 212 configured to rotate about an axis thereof, for example, extending in a vertical direction, a die unit 211 being provided on the rotary die plate 212, the die unit 211 being of a unitary or separate structure with the rotary die plate 212. When of unitary construction, the mold unit 211 has a mold aperture 2111 extending through the rotating mold disc 212; in the case of the split structure, the mold holes of the mold unit 211 communicate with the through holes of the rotary mold tray 212. That is, in the above two structures, the die hole of the die unit communicates with the through hole of the rotary die plate. The mold holes 2111 may be square, circular, oval, etc., for example, which determine the shape of the pressed ice cubes. Illustratively, in an integrated structure, the rotating mold plate 212 has an aperture (or referred to as a through hole) adjacent to and surrounding the sidewall of the mold unit 211 and extends outwardly from the rotating mold plate 212 in a direction substantially perpendicular to the rotating mold plate 212, the aperture defined by the sidewall of the mold unit 211 and the aperture of the rotating mold plate 212 together forming the mold aperture 2111 of the mold unit 211.
The fixed die plate 213 is coaxially stacked with the rotary die plate 212, is provided on a side of the rotary die plate 212 away from the ice pressing push rod 22 and the ice removing push rod 23, is fixedly provided, and has an opening 2131. The opening 2131 may be a through hole or a notch, and penetrates the fixed die plate 213. The opening 2131 shown in fig. 3 is exemplified by a notch. The rotary die plate 212 rotates about its axis relative to the stationary die plate 213 such that the die units 211 on the rotary die plate 212 can be sequentially switched between the filling station a, the ice pressing station B, and the ice removing station C.
The opening 2131 corresponds to the ice removing station C, that is, the opening 2131 is located at the ice removing station C. When the mold unit 211 is positioned at the ice removing station C, an orthographic projection of the mold holes 2111 of the mold unit 211 on the fixed mold tray 213 falls into the opening 2131. The size of the opening 2131 may be slightly larger than the size of the mold hole 2111 so that the ice cubes pressed in the mold unit 211 can be smoothly pushed out of the mold hole 2111 by the ice-removing push rod 23 to avoid obstruction when the ice-removing operation is performed at the ice-removing station C.
In some embodiments, as shown in fig. 1 to 3, the end of the ice pressing push rod 22 near the ice pressing mold 21 substantially conforms to the shape and size of the mold hole 2111 of the mold unit 211, so that the ice pressing push rod 22 can press the ice dust into ice cubes in the mold unit 211.
In some embodiments, as shown in fig. 1 to 3, the ice pressing assembly 20 further includes a limiting member 27 having one end sleeved on the ice removing push rod 23 and the other end sleeved on a guide post 28, and the guide post can slide along the vertical direction, so as to control the ice removing push rod 23 to move along the vertical direction, and prevent the moving direction from deviating from the vertical direction.
In some embodiments, the ice pressing assembly 20 further includes an ice outlet passage 24 connected to the opening 2131, configured to receive ice cubes detached from the mold unit 211, and guide the ice cubes to be output to the outside.
In some embodiments, as shown in fig. 3, the area of the fixed mold tray 213 corresponding to the filling station a and the ice pressing station B is a solid structure, and when the mold unit 211 is located at the filling station a or the ice pressing station B, the fixed mold tray 213 may block the mold hole 2111 of the mold unit 211 or block the through hole of the rotating mold tray. As much as possible, the mold unit 211 prevents leakage from the contact surface of the fixed mold tray 213 and the rotating mold tray when the filling station a performs the filling of the ice chips or the ice pressing station B performs the ice pressing.
In some embodiments, as shown in fig. 1 to 3, the number of the mold units 211 is, for example, 3, and the three mold units 211 are uniformly disposed around the circumference of the rotary mold disc 212. The three mold units 211 are configured to be located at the filling station a, the ice pressing station B, and the ice removing station C, respectively. For example, when the first mold unit 211 is in the filling station a to perform the ice dust filling operation, the second mold unit 211 is in the ice pressing station B to perform the ice pressing operation, and the third mold unit 211 is in the de-icing station C to perform the de-icing operation. When the respective operations of the three mold units 211 are completed, the rotary mold tray 212 is rotated, for example, by 120 degrees counterclockwise, so that the first mold unit 211 is switched to the ice pressing station B to perform the operation of pressing ice cubes, the second mold unit 211 is switched to the ice removing station C to perform the ice removing operation, and the third mold unit 211 is switched to the filling station a to perform the ice chip filling operation. When the respective operations of the three mold units 211 are completed again, the rotary mold tray 212 is rotated again, for example, by 120 degrees counterclockwise, so that the first mold unit 211 is switched to the ice removing station C to perform the ice removing operation, the second mold unit 211 is switched to the filling station a to perform the ice chip filling operation, and the third mold unit 211 is switched to the ice pressing station B to perform the ice pressing operation. When the respective operations of the three mold units 211 are completed again, the rotary mold tray 212 is rotated again, for example, by 120 degrees counterclockwise, so that the first mold unit 211 is switched to the filling station a to perform the ice dust filling operation, the second mold unit 211 is switched to the ice pressing station B to perform the ice pressing operation, and the third mold unit 211 is switched to the ice removing station C to perform the ice removing operation. When the ice making device continuously works, the actions of the three stations (namely, filling ice scraps, compressing ice cubes and removing ice cubes) are performed simultaneously, so that 3 compressed ice cubes, namely, granular ice, can be produced after the rotary die plate 212 rotates for one circle, and the production efficiency is improved.
In some embodiments, as shown in fig. 1 to 3, the ice pressing push rod 22 is disposed parallel to and rigidly connected to the ice removing push rod 23, and when the ice pressing push rod 22 and the ice removing push rod 23 are in a retracted state, an end of the ice removing push rod 23 near the ice pressing mold 21 is closer to the ice pressing mold 21 than an end of the ice pressing push rod 22 near the ice pressing mold 21. For example, the ice pressing push rod 22 and the ice removing push rod 23 are detachably and rigidly connected, and both can be provided with pushing force by the pushing component 25, can simultaneously move towards the ice pressing mold 21 to apply pushing force under the action of the pushing component 25, and can simultaneously retract to a non-pushing position under the action of the pushing component 25 so as to facilitate the rotation of the rotary mold disc 212. The ice pressing push rod 22 and the ice removing push rod 23 are rigidly connected to realize linkage, so that the number of transmission mechanisms can be reduced, and the cost can be reduced. In some embodiments, the pushing strokes of the ice pressing push rod 22 and the ice removing push rod 23 may be the same or different. In the solution shown in fig. 1-3, the pushing stroke of the ice pushing rod 22 is the same as that of the ice pushing rod 23, in which case, when the ice pushing rod 22 and the ice pushing rod 23 are in the retracted state, the end of the ice pushing rod 23 close to the ice pressing mold 21 is closer to the ice pressing mold 21 than the end of the ice pushing rod 22 close to the ice pressing mold 21, which is advantageous for the ice pushing rod 23 to push ice cubes out of the mold unit 211.
In other embodiments, the ice pressing push rod 22 and the ice removing push rod 23 may not be driven by different driving devices.
In some embodiments, as shown in fig. 1-3, the rotating mold disc 212 is rotated about its axis by the mold rotation motor 90. For example, the mold rotating motor 90 rotates the rotating mold disc 212 in a gear engagement.
In some embodiments, the ice making apparatus 100 further includes an ice dust collector 30, for example, in a funnel shape, the ice dust collector 30 corresponding to the filling station a and configured to collect and transfer ice dust produced by the ice dust preparation assembly 10 into a mold unit 211 located at the filling station a, the ice dust collector 30 having a valve at a bottom thereof and configured to switch between open and closed. The bottom of the ice dust collector 30 is aligned with the mold unit 211 at the filling station a. When the valve is in an open state, the ice dust collected in the ice dust collector 30 is filled into the mold unit 211 located at the filling station a, and an ice dust filling operation is performed.
In some embodiments, the ice making apparatus 100 further includes an electronic control part 40, the electronic control part 40 being configured to control opening and closing of the valve, and to control movement of the pushing part 25, thereby controlling pushing and retraction of the ice pressing push rod 22 and the ice removing push rod 23 in a vertical direction. By the design, the three stations of the filling station A, the ice pressing station B and the ice removing station C (namely, filling ice scraps, compressing ice cubes and removing ice cubes) can be executed simultaneously, so that the ice making efficiency is improved.
In some embodiments, the ice pressing assembly 20 further includes an ice scraping member 26, the ice scraping member 26 being disposed between the filling station a and the ice pressing station B and configured to remove excessive ice dust on top of the mold unit 211 after passing through the filling station a. After the mold unit 211 fills the ice dust at the filling station a, excessive ice dust may protrude from the top surface of the mold unit 211, and during the process of rotating the mold disc 212 to drive the mold unit 211 loaded with the ice dust to switch from the filling station a to the ice pressing station B, the ice scraping member 26 is attached to the top surface of the mold unit 211, for example, to remove the excessive ice dust at the top of the mold unit 211, so that the amount of the ice dust in the mold unit 211 switched to the ice pressing station B is kept stable, and the quality of ice cubes obtained by pushing the ice dust is basically equal.
In some embodiments, the ice scraping member 26 may be moved up and down in a vertical direction, and lowered to a predetermined height to scrape off excessive ice dust at the top of the mold unit 211 when only an ice scraping operation needs to be performed.
In some embodiments, the ice making apparatus 100 further includes a recycling bin 50, where the recycling bin 50 is disposed at a side of the ice pressing mold 21 away from the ice pressing push rod 22 and the ice removing push rod 23, and is configured to recycle ice fragments falling off during operation of the ice pressing assembly 20, such as ice fragments scraped off by the ice scraping member 26, and the like. The recycling bin 50 may also recycle raw water formed by melting ice dust or ice cubes during the manufacture of ice cubes by the ice pressing assembly 20.
The ice dust collected in the recycling bin 50 absorbs ambient heat so that the ice dust preparing assembly 10 and the ice pressing assembly 20 are in a low temperature environment, further reducing the rate of melting of the ice dust or ice cubes during the manufacture of the ice dust and the pressing of the ice dust to form ice cubes, and thus ensuring the quality of the granular ice obtained.
Raw water collected in the recovery box 50 can be pumped into a raw water tank described later through a pipeline, so that the raw water can be fully utilized.
In some embodiments, the pushing stroke of the ice pushing rod 22 is adjustable, at the ice pressing station B, the ice scraps in the compression mold unit 211 of the ice pushing rod 22 are gradually hardened into blocks, the compression ratio is determined by the taste of ice cubes selected by a user, and the compression ratio is related to the pushing stroke of the ice pushing rod 22, and different compression ratios are obtained by adjusting different compression strokes of the ice pushing rod 22, so that a soft or firm taste is obtained. In addition, the pushing stroke of the ice pressing push rod 22 also determines the size of the pressed ice cubes, and the pushing stroke of the ice pressing push rod 22 can be adjusted to adjust the size of the pressed ice cubes.
In some embodiments, the pushing force and the dwell time applied by the ice pressing push rod 22 are adjustable, and in the process of adjusting the taste or hardness of the ice cubes, the extrusion force and the dwell time of the ice pressing push rod need to be reasonably controlled, so that the extrusion force can be transmitted from the extrusion contact surface to the interior of the ice cubes, and the overall density of the ice cubes is substantially equal, so that the ice cubes with uniform taste are obtained. Illustratively, the dwell time may be a time period during which the ice pushing lever 22 pushes the ice dust, and maintains a pressure applied to the ice dust for a certain period of time after the ice dust is moved to a predetermined position; or the ice pressing pushrod 22 presses the ice dust at a constant pressure or pressure range for a certain period of time, etc.
As can be seen from the above description, the present disclosure ensures uniform shape of the granular ice through shaping of the mold. The problem that the ice strips are broken by extrusion to form granular ice in the related art, so that the breaking position is uncontrollable and the shape and the size of the granular ice are unstable is solved.
In some embodiments, as shown in fig. 1 to 3, the ice dust preparation assembly 10 includes a water tray 11, an ice making roller 12, and a scraper 13.
The water dipping tray 11, for example, a box-shaped container with an open top surface, is configured to receive the raw water, and a depth of the raw water in the water dipping tray 11 is maintained within a predetermined range to ensure that a portion of the ice making roller 12 adjacent to the water dipping tray 11 can contact the raw water received in the water dipping tray.
The ice making roller 12 is located above the water tray 11 and is configured to rotate along its axis, for example, extending in a horizontal direction perpendicular to the vertical direction. A part of the ice making roller 12, which is close to the water soaking tray 11, is configured to contact the raw water contained in the water soaking tray, and a refrigerant is introduced into the ice making roller 12, so that the ice making roller 12 forms an ice layer on the rotating surface 121 of the ice making roller 12 in the rotating process.
A scraper 13 is provided at one side of the ice making roller 12 and configured to scrape ice dust from a rotation surface 121 of the ice making roller 12.
When the ice dust preparation assembly 10 is used for preparing ice dust, the refrigerant is sent into the inner cavity of the ice making roller 12 through the pipeline, so that the circumferential inner side walls of the ice making roller 12 are uniformly contacted with the refrigerant. For example, the ice-making roller 12 may be made of metal, such as food grade stainless steel, which not only ensures food safety, but also provides good heat transfer properties. The ice making roller 12 made of a metal material has substantially the same temperature of the circumferential side wall during the preparation of the ice dust, and thus, as the ice making roller 12 rotates, water adhered to the rotating surface 121 of the ice making roller 12 exchanges heat with the refrigerant, thereby forming an ice layer on the circumferential outer wall of the ice making roller 12, and the ice layer is gradually frozen during the rotation to form a stable ice layer. Then, as the ice making roller 12 rotates, the scraper 13 scrapes ice dust from the ice layer on the rotating surface 121 of the ice making roller 12, forming snowflake-like fine ice dust.
Based on the above arrangement, the mode of adopting the ice making roller to rotationally dip in raw material water and introducing refrigerant into the ice making roller can form a uniform ice layer on the surface of the ice making roller rapidly, the contact area of the refrigerant and the raw material water is large, the heat transfer efficiency is high, and compared with a screw ice maker in the related art, the ice making area is larger and the ice making speed is faster. The scraping knife is used for scraping the ice scraps from the ice layer on the rotating surface of the ice making roller, so that even and fine ice scraps can be quickly formed. The embodiment of the disclosure fully utilizes the characteristic of large surface size of the outer wall of the ice making roller, increases the contact area of the refrigeration surface and raw water, and improves the heat exchange efficiency, thereby obviously improving the preparation efficiency of ice scraps and finally solving the problem of slow supply of ice scraps raw material when the granular ice is made in the related technology.
The production efficiency of the ice dust preparation assembly adopted in the disclosure per unit time is greatly improved compared with that of a granular ice maker (or referred to as an ice maker) in the related art, so that the ice dust production efficiency per unit time is improved, and the requirement of a user for a large amount of granular ice (nugget ice) in a short time is met.
The scraper 13 is located substantially above the ice dust collector 30, and the ice dust scraped by the scraper 13 falls substantially into the ice dust collector 30 to be supplied to the ice pressing assembly 20.
In some embodiments, as shown in fig. 1 to 3, the scraper 13 and the ice dust collector 30 are both positioned above the recycling bin 50, and the ice dust scraped by the scraper 13 and not collected by the ice dust collector 30 may fall into the recycling bin 50 for recycling.
In the ice making roller 12, the refrigerant after heat exchange is sent to the heat exchange member 60, such as a compressor, a condenser, etc., and is changed into a low-temperature medium after heat exchange, and is sent to the refrigeration roller 12 again in a circulating manner. The exchanged heat is diffused to the external environment through the heat radiating member 70. The heat sink 70 may include, for example, heat sink fins, heat pipes, and/or fans.
In some embodiments, the ice making roller 12 may be driven by a roller motor 80, and the gear portion 81 of the roller motor 80 is connected to the gear portion 122 of the ice making roller 12, for example, through a chain, so that the ice making roller is driven to rotate by the roller motor 80.
In some embodiments, the ice chip preparation assembly 10 further includes a raw water tank 14, the raw water tank 14, for example, located above the ice making roller 12, configured to provide raw water into the water tray 11.
In some embodiments, the raw water tank 14 supplies raw water to the water tray 11 through a water pipe 141. The float valve is arranged in the water dipping tray 11, when the raw water in the water dipping tray 11 is lower than a preset water level, the float valve enables the water pipe 141 to be conducted so as to supplement the raw water to the water dipping tray 11, and when the raw water in the water dipping tray 11 reaches a target water level, the float valve enables the water pipe 141 to be cut off. The predetermined water level is less than or equal to the target water level. The floating ball valve is arranged to automatically feed water when the water level of the roller dipping tray 11 is low and automatically stop feeding water when the water level is high, so that the water level in the water dipping tray 11 is kept at a certain height, and the water dipping requirement when the ice making roller 12 rotates is met. The water level control is realized through a mechanical structure, so that the safety problem and the waterproof sealing problem of the circuit caused by using the circuit control are avoided, and the production cost is reduced.
The following specifically explains the operation principle of the ice making apparatus provided by some embodiments of the present disclosure, which includes an ice dust preparation process and an ice cubes preparation process.
In the process of preparing ice scraps, raw water required for ice making is stored in the raw water tank 14 through a filling opening at the top of the equipment, the lower part of the raw water tank 14 stretches into the water dipping tray 11 through a water pipe 141 of the raw water tank, a floating ball valve is connected to the lower part of the water pipe 141, water can be automatically fed when the water dipping tray 11 is low in liquid level, water feeding is automatically stopped when the water dipping tray is high in liquid level, and therefore the water level in the water dipping tray 11 is kept at a certain height, and the water dipping requirement of the ice making roller when the rotary surface 121 works is met.
When the ice making roller 12 rotates, the refrigerant is sent into the inner cavity of the ice making roller 12 through the pipeline, so that the circumferential inner side walls of the ice making roller 12 are contacted with the refrigerant. The temperature of the circumferential wall surface of the ice making roller 12 is substantially the same, and water adhered to the ice making roller 12 exchanges heat with the refrigerant to form an ice layer on the circumferential outer wall of the ice making roller 12, i.e., the rotation surface 121. The roller motor 80 drives the ice making roller 12 to rotate, and the ice layer is gradually frozen during the rotation process to form a stable ice layer, and the stable ice layer is scraped at the scraper 13 during the rotation process of the ice making roller 12 to form snowflake fine ice dust.
During the ice making process, the ice scraps scraped by the scraper 13 are collected in the ice scraps collector 30, the top opening of the ice scraps collector 30 is used for collecting the scraped ice scraps, and the bottom of the ice scraps collector 30 is provided with a valve, and the valve is electrically connected with the electric control part 40. When the bottom opening of the ice dust collector 30 is aligned with the mold unit 211 of the ice pressing mold 21 at the filling station a, the valve is opened and the ice dust slides down into the mold unit 211 by gravity. The rotary die plate 212 is switched over at three stations at a rotation step of 120 ° counterclockwise under the drive of the die turning motor 90. When the ice dust is filled for a certain time, the rotary die plate 212 is controlled to rotate for 120 degrees, so that the other die unit 211 switched to the filling station A continuously receives the ice dust, and the die unit 211 just filled with the ice dust is switched to the ice pressing station B, and in the switching process, the excessive ice dust on the die unit 211 just filled with the ice dust is scraped by the ice scraping component 26, so that the injected ice dust amount is kept stable. At the ice pressing station B, the electronic control part 40 controls the ice pressing push rod 22 to start pushing downward, and the ice dust of the compression mold unit 211 is gradually hardened into a block. After the ice cubes are compressed, the ice pressing push rod 22 is controlled to retract, and the rotary die plate 212 is controlled to rotate to switch the die unit 211 carrying the compressed ice cubes to the ice removing station C, where the ice removing push rod 23 pushes down, so that the ice cubes made in the die unit 211 are provided to the user through the ice discharging passage 24.
The ice making machine adopts the combination of ice making scraps with water dipping by the rollers and ice making in a multi-station pushing mode, and can improve the ice making efficiency of the ice scraps and the ice making efficiency of ice cubes. Specifically, the characteristics that the outer wall surface of the ice-making roller is large in size are fully utilized, the contact area between the refrigerating surface and raw water is increased, and the heat exchange efficiency is improved, so that the preparation efficiency of ice scraps is remarkably improved, and actions of three stations (namely filling of the ice scraps, compression of ice cubes and ice cube removal) in a multi-station pushing mode are simultaneously carried out, so that 3 compression of ice cubes can be produced when the rotary die plate rotates for every circle, and the production efficiency is improved.
