Description

Technical Field

[0001] This application belongs to the field of shaved ice processing technology, and particularly relates to a rotary receiving tray and a shaved ice machine. Background Technology

[0002] A shaved ice machine is a machine used to make shaved ice (also called shaved ice or slush). It creates a snowflake-like texture by shaving ice into fine shavings, and is commonly used in desserts and cold drinks. Currently, existing shaved ice machines typically lack a rotating receiving tray, causing the shaved ice to tend to accumulate in one spot on the container, resulting in uneven distribution. For example, a cold drink device disclosed in Chinese patent application CN120323553A has a detachable, non-rotating receiving tray at the lower front of its housing assembly. When making shaved ice, the container is placed on the tray, leading to localized accumulation and even overflow of the shaved ice, making even distribution impossible. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application embodiment is to provide a rotating receiving tray with uniform material receiving.

[0004] The technical solution adopted in this application embodiment is a rotary receiving tray for use in a shaved ice machine, the rotary receiving tray comprising:

[0005] A tray assembly is located below the ice outlet of the slush ice machine;

[0006] A turntable assembly is disposed on the tray assembly, and the upper part of the turntable assembly is exposed outside the top of the tray assembly;

[0007] A transmission assembly, one end of which is connected to a power mechanism located inside the shaved ice machine, and the other end of which is connected to the turntable assembly, is used to transmit the power of the power mechanism to the turntable assembly so that the turntable assembly rotates.

[0008] In an optional embodiment, the tray assembly includes a tray and a top cover. The top of the tray is open, and the top cover is removably disposed over the open top of the tray. The top cover has a through-hole for exposing the top of the turntable assembly. By providing a through-hole in the top cover to expose the top of the turntable assembly, it supports and drives the ice-receiving container to rotate.

[0009] In an optional embodiment, the turntable assembly includes a turntable and a turntable shaft. The turntable is located within a through hole in the top cover, and the upper surface of the turntable protrudes from the upper surface of the top cover. The turntable shaft is connected to the lower surface of the turntable and is also connected to the transmission assembly. The turntable assembly has a simple and reasonable structure and is capable of supporting and driving the ice-receiving container to rotate.

[0010] In an optional embodiment, a turntable gear is provided at the lower end of the turntable shaft;

[0011] The transmission assembly includes a transmission shaft and a transmission gear located at the first end of the transmission shaft. The transmission gear meshes with the turntable gear. The second end of the transmission shaft is connected to the power mechanism. When the power mechanism drives the transmission shaft to rotate, the transmission shaft drives the transmission gear and the turntable gear to rotate, and the turntable gear drives the turntable shaft and the turntable to rotate. In this way, the power from the power mechanism in the shaved ice machine is transmitted to the turntable, realizing the rotation of the turntable. The structure is simple and reasonable, and easy to implement.

[0012] In an optional embodiment, the transmission assembly further includes a connector located at the second end of the transmission shaft; the output shaft of the power mechanism is provided with an output device exposed to the shaved ice machine. When the rotating receiving tray is installed in the shaved ice machine, the connector is coupled to the output device so that when the power mechanism is started, the transmission shaft is driven to rotate through the coupled connector and the output device. The connection between the transmission shaft and the power mechanism is simple and reliable, and can transmit power smoothly and effectively.

[0013] In an optional embodiment, the tray is provided with a support base, the top of the support base is provided with an annular boss that protrudes upward from the top surface of the support base, and the inner circumferential side of the annular boss is provided with an annular groove.

[0014] The turntable has an annular protrusion on its outer periphery, and the turntable is located within the cavity formed by the annular protrusion, with the annular protrusion extending into the annular groove. This ensures that the turntable will not shift or wobble during rotation.

[0015] In an optional embodiment, the support base is provided with a shaft seat, the shaft seat is provided with a shaft hole, and the drive shaft passes through the shaft hole to be supported on the shaft seat.

[0016] In an optional embodiment, the drive shaft is arranged laterally, and the drive gear at the first end of the drive shaft is a bevel gear;

[0017] The turntable shaft is vertically oriented, and the turntable gear at the lower end of the turntable shaft is a bevel gear. Through the meshing of the two bevel gears, the rotation of the drive shaft around the horizontal axis is converted into the rotation of the turntable shaft and the turntable around the vertical axis.

[0018] This application also provides a slush ice machine, including a main unit, a power mechanism disposed within the main unit, and a slush ice-making module disposed on the upper part of the main unit. The slush ice-making module has an ice outlet with a downward opening. The slush ice machine also includes a rotating receiving tray as described in any of the above embodiments. The rotating receiving tray is disposed below the ice outlet and connected to the power mechanism, which drives the turntable assembly of the rotating receiving tray to rotate. This slush ice machine can achieve a uniform filling effect.

[0019] In an optional embodiment, the outer side of the main unit near the bottom is recessed inward to form a groove, and a first buckle is protruding on the bottom wall of the groove;

[0020] The power mechanism includes a motor, one end of the motor's output shaft passing through the bottom wall and extending into the slot cavity and connected to the output device;

[0021] The tray assembly has a second latch on its first side, and one end of the transmission component extends out of the first side of the tray assembly and connects to the connector. When the rotating receiving tray is installed on the main unit with the first side of the tray assembly facing the cavity, the second latch engages with the first latch, and the connector couples with the output device. The rotating tray assembly is detachably connected to the main unit, facilitating its removal and cleaning.

[0022] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: This application uses the power mechanism of the snow ice machine to provide power to the rotating receiving tray, which not only achieves the purpose of uniform material receiving, but also improves the safety of cleaning by preventing water from entering the rotating receiving tray during ice receiving and cleaning, since there are no electronic components inside the rotating receiving tray.

[0023] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this application.

[0043] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0044] This application provides a rotating receiving tray for use in a shaved ice machine. For example... Figures 1 to 3 As shown, the rotating receiving tray includes a tray assembly 1, a turntable assembly 2, and a transmission assembly 3. The tray assembly 1 is located below the ice outlet 61 of the shaved ice machine. The turntable assembly 2 is located on the tray assembly 1, and the upper part of the turntable assembly 2 is exposed outside the top of the tray assembly 1. One end of the transmission assembly 3 is connected to a power mechanism located inside the shaved ice machine, and the other end of the transmission assembly 3 is connected to the turntable assembly 2. The transmission assembly 3 is used to transmit power from the power mechanism to the turntable assembly 2, so that the turntable assembly 2 rotates.

[0045] The rotating receiving tray of this application embodiment can drive the ice receiving container placed on it to rotate through the rotatable turntable assembly 2, so as to solve the problem of uneven receiving. Moreover, since the power mechanism is set on the slush ice machine, there are no electronic components and power supply on the turntable assembly 2, so there is no safety problem such as water ingress risk during the use and cleaning of the rotating receiving tray.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the tray assembly 1 includes a tray 11 and a top cover 12. The top of the tray 11 is open, and the top cover 12 is detachably installed over the open top of the tray 11 to form a cavity 111 with the tray 11. The top cover 12 has a through hole 121 communicating with the cavity 111. The turntable assembly 2 is disposed inside the tray 11, and the top of the turntable assembly 2 is exposed outside the through hole 121 so that when the ice receiving container is placed on the rotating receiving tray, it can be supported by the top of the turntable assembly 2 and rotate with the turntable assembly 2. By providing a through hole 121 on the top cover 12, the top of the turntable assembly 2 is exposed to support the ice receiving container, and the structure is reasonably designed.

[0047] like Figure 1 and Figure 2 As shown, the through hole 121 is roughly located near the center of the top cover 12. A drainage hole 122 is provided around the through hole 121 on the top cover 12. When ice is discharged, the splashed ice water from the ice-collecting container enters the cavity 111 through the drainage hole 122 for collection. A removable bottom cover 13 can be provided at the bottom of the tray 11, making it easier to clean the inside of the tray 11 by removing the bottom cover 13.

[0048] In some embodiments, such as Figure 2 As shown, the turntable assembly 2 includes a turntable 21 and a turntable shaft 22. The turntable 21 is located within the through hole 121 of the top cover 12, and the upper surface of the turntable 21 protrudes from the upper surface of the top cover 12 (see Figure 1). Figure 1 The turntable shaft 22 is connected to the lower surface of the turntable 21. The turntable shaft 22 is located in the cavity 111 of the tray 11 and is connected to the transmission assembly 3. The turntable assembly 2 has a simple structure. Through the upper surface of the turntable 21 protruding from the through hole 121, it can support and drive the ice-receiving container to rotate.

[0049] like Figure 4 As shown, a turntable gear 23 is fixedly mounted on the lower end of the turntable shaft 22. The transmission assembly 3 includes a transmission shaft 31 and a transmission gear 32 located at the first end of the transmission shaft 31. The transmission gear 32 meshes with the turntable gear 23. The second end of the transmission shaft 31 is connected to the power mechanism. When the power mechanism drives the transmission shaft 31 to rotate, the transmission shaft 31 drives the transmission gear 32 and the turntable gear 23 to rotate. The turntable gear 23 drives the turntable shaft 22 and the turntable 21 to rotate. In this way, the power of the power mechanism in the shaved ice machine is transmitted to the turntable 21, realizing the rotation of the turntable 21. The structure is simple and reasonable, and easy to implement.

[0050] In some embodiments, such as Figure 2 and Figure 4 As shown, the transmission assembly 3 also includes a connector 33 located at the second end of the transmission shaft 31. The power mechanism may include a motor 5, and an output device 51 is provided on the output shaft of the motor 5, which is exposed outside the main body 4 of the shaved ice machine. When the rotating receiving tray is mounted on the main body 4 of the shaved ice machine, the connector 33 at the second end of the transmission shaft 31 is coupled to the output device 51 on the output shaft of the motor 5, so that when the motor 5 is started, the transmission shaft 31 is driven to rotate through the coupled output device 51 and connector 33. The connection between the transmission shaft 31 and the power mechanism is simple and reliable, and can transmit power smoothly and effectively.

[0051] In some embodiments, such as Figure 5As shown, a support seat 112 is provided inside the cavity 111 of the tray 11. The top of the support seat 112 has an annular boss 113 protruding upwards from its top surface, forming a cavity. An annular groove 1131 is provided on the inner circumference of the annular boss 113. An annular ridge is provided on the outer circumference of the turntable 21. The turntable 21 is located within the annular cavity, and the annular ridge extends into the annular groove 1131. (See also...) Figure 4 The annular protrusion and the annular groove 1131 work together to limit the rotation of the turntable 21, ensuring that the turntable 21 rotates smoothly around the turntable axis 22 and preventing deviation.

[0052] like Figure 5 As shown, one end of the support base 112 is connected to the inner wall of the first side of the tray 11, and the other end of the support base 112 is spaced from the second side of the tray 11, with the second side of the tray 11 being opposite to the first side. The support base 112 is a hollow cuboid extending from the first side to the second side of the tray 11. An annular boss 113 is located near the second end of the support base 112, approximately in the center of the tray 11. The turntable 21 is circular, and the cavity enclosed by the annular boss 113 is a circular cavity adapted to the turntable 21. The circular cavity communicates with the inner cavity of the support base 112, allowing the turntable shaft 22 connected to the lower surface of the turntable 21 to be placed within the inner cavity of the support base 112.

[0053] For example, such as Figure 4 As shown, a bearing seat 114 is provided in the inner cavity of the support base 112. The bearing seat 114 has a shaft hole, through which the drive shaft 31 passes to be supported on the bearing seat 114. By providing the bearing seat 114 in the support base 112, the drive shaft 31 can be supported, avoiding the drive shaft 31 from being suspended in the air with only connection points at both ends, which would lead to unstable rotation.

[0054] like Figure 4 As shown, the drive shaft 31 is arranged horizontally, and the drive gear 32 at the first end of the drive shaft 31 is a bevel gear. The turntable shaft 22 is arranged vertically, and the turntable gear 23 at the lower end of the turntable shaft 22 is a bevel gear. By meshing the two bevel gears, the direction of rotation is changed, transforming the rotation of the drive shaft 31 around the horizontal axis into the rotation of the turntable shaft 22 and the turntable 21 around the vertical axis, so as to drive the ice-receiving container to rotate around the vertical axis.

[0055] To support the laterally positioned drive shaft 31, the support base 112 is provided with two shaft seats 114. The first shaft seat 114 is located in the inner cavity of the support base 112 and is connected to the inner side of the top wall of the support base 112. The end of the support base 112 corresponding to the first side of the tray 11 is open and sealed by the first side of the tray 11. The second shaft seat 114 is located on the inner wall of the first side of the tray 11. The first side of the tray 11 has a through hole that communicates with and is coaxial with the shaft hole of the second shaft seat 114. The axes of the shaft holes of the two shaft seats 114 are collinear and approximately horizontal.

[0056] Since the rotational speed of the drive shaft 31 is relatively slow, a bearing is not required between the drive shaft 31 and the shaft hole of the bearing seat 114; a clearance fit is sufficient.

[0057] This application also provides a shaved ice machine, such as... Figure 3 , Figure 6 and Figure 7 As shown, the shaved ice machine includes a main unit 4, a power mechanism disposed within the main unit 4, and a shaved ice making module 6 disposed on the upper part of the main unit 4. The shaved ice making module 6 has an ice outlet 61 with its opening facing downwards. The shaved ice machine also includes a rotating receiving tray as described in any of the above embodiments. The rotating receiving tray is disposed below the ice outlet 61 and connected to the power mechanism, which drives the turntable assembly 2 of the rotating receiving tray to rotate. Because the shaved ice machine of this embodiment has a rotating receiving tray below its ice outlet 61, when an ice container is placed on the rotating receiving tray, the shaved ice coming out of the ice outlet 61 will fall evenly into the ice container, preventing it from accumulating in one position within the ice container, thus achieving a uniform filling effect.

[0058] In some embodiments, such as Figure 6 As shown, the outer side of the main unit 4 near the bottom is recessed inward to form a groove 41, and a first buckle 42 is protruding on the bottom wall (the wall opposite the groove opening) of the groove 41. The power mechanism includes a motor 5, one end of the output shaft of the motor 5 passes through the bottom wall and extends into the groove 41 and is connected to the output device 51, which is located inside the groove 41.

[0059] like Figure 1 As shown, a second latch 115 is provided on the first side of the tray 11, and one end of the drive shaft 31 of the transmission assembly 3 extends out of the first side of the tray 11 and connects to the connector 33. Figure 6 As shown, when the rotating receiving tray is mounted on the main unit 4 with the first side of the tray 11 facing the cavity 41, the second latch 115 engages with the first latch 42, and the connector 33 couples with the output device 51. Figure 6 The direction of the middle arrow indicates the loading direction of the rotating receiving tray. Figure 6The opposite direction of the middle arrow indicates the direction for removing the rotating receiving tray. The rotating tray assembly 2 is detachably connected to the main unit 4 via two latches, facilitating its removal and cleaning. Furthermore, since the rotating tray assembly 2 does not contain electronic components, there are no safety risks such as water ingress during cleaning.

[0060] Continue to combine Figure 1 The drive shaft 31 extends from the center of the first side of the tray 11, so that the connector 33 is approximately located in the middle of the first side of the tray 11. Two second latches 115 are provided, located on either side of the connector 33. Figure 6 As shown, the bottom wall of the cavity 41 is provided with two first buckles 42 located on both sides of the output device 51. The two first buckles 42 and the two second buckles 115 are fastened in a one-to-one correspondence, so that the rotating receiving tray can be stably connected to the main unit 4.

[0061] When using the shaved ice machine, first install the rotating receiving tray on the lower side of the main unit 4, below the ice outlet 61. The connector 33 of the transmission component 3 is coupled to the output 51 of the motor 5. The shaved ice machine starts to make shaved ice. The electronic control module 7 of the shaved ice machine drives the motor 5 to rotate. The output 51 of the motor 5 transmits power to the transmission shaft 31 assembly through the connector 33. The transmission shaft 31 assembly transmits power to the turntable assembly 2 through the turntable gear 23, realizing the rotation of the turntable assembly 2. At this time, the ice receiving container is placed on the turntable 21 of the turntable assembly 2 and rotates with the turntable 21 to achieve uniform filling.

[0062] After the shaved ice is made, the rotating receiving tray can be removed from the main unit 4 for cleaning. Since there are no electrical components inside, the top cover 12 and / or bottom cover 13 can be opened to rinse with clean water or wipe with a cloth without any safety hazards.

[0063] Understandably, during the ice-making process, the rotation of the turntable assembly 2 can be controlled by opening and closing the power mechanism as needed. In other words, the ice-receiving process can be carried out in either a rotating or non-rotating state.

[0064] In addition, to achieve a better uniform loading effect, the ice receiving container can be set in the center or off-center on the turntable assembly 2, depending on the needs.

[0065] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
