Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, especially to a shaving ice machine. BACKGROUND

[0002] With the improvement of living standards, the types and functions of household appliances are increasing, and the shaving ice machine can be used in combination with the ice making function of the refrigerator to break the ice blocks to obtain a device for making various slush beverages.

[0003] The ice crushing device and the refrigerator disclosed in Chinese patent CN111829239A include a shell assembly including a shell and an ice bucket supported in the shell; an ice crushing mechanism arranged in the ice bucket, the ice crushing mechanism including an ice cutter shaft, a plurality of movable ice cutters and a plurality of fixed ice cutters arranged on the ice cutter shaft; a driving mechanism for rotating the ice bucket or the ice cutter shaft; the shell assembly further includes a ice discharging base plate arranged at the bottom of the ice bucket, the ice discharging base plate is provided with an ice discharging port communicated with the ice bucket, the ice blocks produced by the ice making machine are crushed by the ice crushing mechanism and then discharged from the ice discharging port; a stopper assembly is arranged in the ice bucket; when the ice crushing device is in a first state, the stopper assembly is in an initial state and forms a stop surface at the ice discharging port to prevent the ice blocks from falling; when the ice crushing device is in a second state, the stopper assembly changes position or shape under the action of an external force to remove the stop surface, and after the external force disappears, the stopper assembly returns to the initial state and forms the stop surface again.

[0004] The ice crushing device in the above-mentioned prior art crushes ice by cooperation of movable ice cutters and fixed ice cutters, and the overall structure is relatively complex. In use of the existing shaving ice device, the ice crushing blades cut the ice blocks by rotating, and the cutting probability is limited by the number of blades, the running speed, and the random distribution of ice blocks. The shaving ice machines on the market generally have low shaving ice efficiency and high ice block residue.

[0005] Therefore, the prior art needs to be improved and developed. UTILITY MODEL CONTENT

[0006] The utility model aims at the defects and deficiencies of the prior art, and provides a shaving ice machine with reasonable structure, high ice crushing efficiency and less residue.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0008] The present invention discloses an ice shaving machine, comprising a main body, an ice receiving component, and a drive component. The main body is mounted on the ice receiving component, and a base is provided at the bottom of the main body. A centering column is provided on the base, and an ice bucket rotatably connected to the centering column is provided inside the main body. A pusher is provided inside the ice bucket. The drive component is drivenly connected to the ice bucket. The portion of the upper surface of the base inside the lower port of the ice bucket forms a working surface, and an ice outlet and a shaver blade are provided on the working surface. An ice shaving blade is provided at the ice outlet.

[0009] The centering column is located at the center of the working surface, that is, concentrically arranged with the rotation center axis of the ice bucket. The drive assembly drives the ice bucket to rotate on the upper surface of the base, thereby defining the working surface. Specifically, an annular sleeve is provided on the base, and the lower end of the ice bucket passes through the sleeve, so that its lower port is concentric with the base and can rotate relative to it. At the same time, a sealing structure can be provided between the lower port of the ice bucket and the sleeve or the base to prevent ice fragments from spilling out of the ice bucket.

[0010] Understandably, under the influence of gravity, the ice blocks inside the ice bucket always exert a pressure that tends towards the working surface. As the ice bucket rotates, the pusher causes the ice blocks to rotate linearly around the centering column. That is, the ice blocks at the bottom of the ice bucket slide on the working surface, thereby continuously impacting the shaver blade and the ice-shaving blade.

[0011] The shaver blade can create deep scratches on the surface of the ice block when it collides with the ice block, or break the ice block into several pieces. Then, when the ice block rotates to the ice outlet, it hits the shaver blade, which can cut the ice block better and improve the shavering effect and efficiency.

[0012] According to the above scheme, the ice bucket is equipped with a bushing, which is rotatably connected to a centering column. The pusher is a propeller blade, which is disposed between the outer wall of the bushing and the inner wall of the ice bucket. When the ice bucket rotates, the propeller blade can drive the ice blocks inside the ice bucket toward the working surface, and the propeller blade can also drive the ice blocks inside the ice bucket to slide on the working surface. It can be understood that the propeller blade plays a spiral compression role. The spiral direction of the propeller blade is consistent with the rotation direction of the ice bucket. The pitch of the propeller blade is greater than the size of the ice block. Simply put, if the ice block is square, the pitch of the propeller blade is greater than the side length of the ice block; if the ice block is round, the pitch of the propeller blade is greater than the diameter of the ice block.

[0013] Furthermore, the ice bucket is rotatably connected to the centering column via a bushing, and the propeller blades are connected to the bushing and the ice bucket respectively. The aforementioned drive assembly drives the ice bucket to rotate around the centering column, and the propeller blades can squeeze the ice blocks to always tend towards the working surface, preventing the ice blocks from spinning empty inside the ice bucket and improving the ice shaving efficiency.

[0014] According to the above scheme, the ice shaving knife includes a first knife holder and a shaving blade. The shaving blade passes through the ice outlet and is fixedly connected to the bottom surface of the base through the first knife holder. The shaving blade forms an angle C with the working surface, and the blade edge extends out of the working surface. The ice outlet is arranged radially along the working surface. The shaving blade is inclined so that its blade passes through the ice outlet and extends out of the working surface. The blade edge is relatively parallel to the working surface. When ice blocks slide along the working surface, they can impact the blade edge and be cut by the shaving blade to form ice shavings and ice sand. The first knife holder is the assembly structure of the shaving blade on the base. The first knife holder is a conventional technology and only needs to meet the installation and fixing requirements of the shaving blade, so it will not be described in detail here.

[0015] According to the above scheme, the blade of the planer is provided with several fracture points, thereby making the blade serrated. Furthermore, the serrated blade reduces the contact area between the planer and the ice, which can increase the cutting force of the planer, making it easier to cut and break the ice.

[0016] According to the above scheme, the crushing blade includes a second blade holder and a plurality of crushing heads. The plurality of crushing heads are fixedly connected to the bottom surface of the base through the second blade holder, and the upper ends of the plurality of crushing heads protrude from the working surface. The second blade holder is used to mount the crushing heads on the base. Specifically, the second blade holder is provided with a plurality of crushing heads. The second blade holder is fixed to the bottom surface of the base. The base needs to be provided with some through holes so that the crushing heads can pass through the base and protrude from the working surface, so that when the ice block slides along the working surface, it can collide with the crushing heads.

[0017] According to the above scheme, the plurality of crushing heads are arranged radially and spaced apart along the working surface. A first crushing blade is provided on one side of each crushing head, and the first crushing blade is positioned opposite to the rotation direction of the ice bucket and perpendicular to the working surface. It can be understood that the spaced arrangement of the crushing heads can expand the effective range of the crushing blades on the working surface. When the ice bucket rotates, the ice at the bottom of the ice bucket moves linearly around the centering column on the working surface, with the first crushing blade facing the direction of the ice. Under the action of the propeller blades and gravity, the ice has pressure tending towards the working surface. The linearly moving ice collides with the crushing heads, and the first crushing blade can scratch the surface of the ice or directly shatter it. As the ice continues to rotate and passes through the ice outlet, it can be more easily broken or cut by the ice shaving blades to form slush.

[0018] According to the above scheme, the upper end of the shattering head is provided with a second shattering blade, which can deepen the scratch and increase the probability of the shattering head breaking ice, thereby improving the ice shaving efficiency.

[0019] According to the above scheme, the ice receiving component includes a base and an ice cup. A stirrer is installed inside the ice cup, and a centering shaft is located at the bottom of the ice cup. The lower end of the stirrer is rotatably connected to the centering shaft. A rotatable drive shaft passes through the centering shaft, and the upper end of the drive shaft is fixedly connected to a bushing. The lower end of the drive shaft passes through the base and has an output interface. When the ice cup is inserted into the base, it is paired with the ice outlet, and the upper end of the stirrer is engaged with the output interface. It can be understood that the base has an open space, allowing the ice cup to be inserted into the base and paired with the ice outlet on the base. The ice cubes in the ice bucket are crushed and fall directly into the ice cup. Preferably, the ice cup contains a stirrer, and the ice bucket can drive the stirrer to rotate as a whole via the drive shaft. Ingredients are added into the ice cup, and as the slush continuously falls in, the stirrer mixes the slush with the ingredients in the ice cup, thus creating a slushy beverage.

[0020] According to the above scheme, the bottom of the base is provided with a spiral lifting groove, and the bottom of the ice cup is provided with a spiral slider. The spiral slider is inserted into the spiral lifting groove and engages with it, thereby connecting the stirrer inside the ice cup to the output interface. The spiral lifting groove is equivalent to a circular track with an opening on its side. When the ice cup is placed into the base, the spiral slider is inserted into the spiral lifting groove along the opening and engages with it. The ice cup is rotated at a certain angle, and through the threaded transmission of the spiral slider and the spiral lifting groove, the ice cup is lifted so that its upper end contacts the connecting piece on the bottom surface of the base, and the upper end of the stirrer engages with the output interface to achieve a transmission connection.

[0021] This utility model discloses an ice shaving machine with a simple and compact overall structure. When the ice bucket rotates, the pusher pushes the ice blocks inside to slide on the working surface to prevent them from spinning dry. The ice blocks are scratched by the impact of the crushing blade, and the ice blocks are broken into pieces or torn. When they are hit by the ice shaving blade again, they are easily crushed, which can effectively improve the ice shaving efficiency and reduce ice residue. Attached Figure Description

[0029] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-5 As shown, the ice shaving machine of this utility model includes a main body 1, an ice receiving component, and a drive component. The main body 1 is mounted on the ice receiving component. A base 2 is provided at the bottom of the main body 1, and a centering column 21 is provided on the base 2. An ice bucket 12, rotatably connected to the centering column 21, is provided inside the main body 1, and a pusher is provided inside the ice bucket 12. The drive component is drivenly connected to the ice bucket 12. The portion of the upper surface of the base 2 within the lower port of the ice bucket 12 forms a working surface 22, and an ice outlet 221 and a shaver blade are provided on the working surface 22. The centering column 21 is located at the center of the working surface 22, that is, it is concentrically arranged with the rotation center axis of the ice bucket 12. The drive component drives the ice bucket 12 to rotate on the upper surface of the base 2, thereby defining the working surface 22. Specifically, an annular sleeve 25 is provided on the base 2, and the lower end of the ice bucket 12 passes through the sleeve 25, so that its lower port is concentric with the base 2 and can rotate relative to it. At the same time, a sealing structure can be provided between the lower port of the ice bucket 12 and the sleeve 25 or the base 2 to prevent ice fragments from spilling out of the ice bucket 12.

[0031] Understandably, under the influence of gravity, the ice blocks inside the ice bucket 12 always have a pressure that tends towards the working surface 22. As the ice bucket 12 rotates, the pusher drives the ice blocks to make linear rotational motion around the centering column 21. That is, the ice blocks at the bottom of the ice bucket 12 slide on the working surface 22, thereby continuously impacting the breaking blade and the ice shaving blade.

[0032] The shaver blade can create deep scratches on the surface of the ice block when it collides with the ice block, or break the ice block into several pieces. Then, when the ice block rotates to the ice outlet 221, it hits the shaver blade, which allows the shaver blade to cut the ice block better, improving the shaver effect and efficiency.

[0033] The ice bucket 12 is equipped with a bushing 13, which is rotatably connected to a centering column 21. The pusher is a propeller blade 14, which is disposed between the outer wall of the bushing 13 and the inner wall of the ice bucket 12. When the ice bucket 12 rotates, the propeller blade 14 can drive the ice blocks inside the ice bucket 12 toward the working surface 22, and the propeller blade 14 can also drive the ice blocks inside the ice bucket 12 to slide on the working surface 22. It can be understood that the propeller blade 14 plays a spiral extrusion role. The spiral direction of the propeller blade 14 is consistent with the rotation direction of the ice bucket 12. The pitch of the propeller blade 14 is greater than the size of the ice block. Simply put, if the ice block is square, the pitch of the propeller blade 14 is greater than the side length of the ice block; if the ice block is round, the pitch of the propeller blade 14 is greater than the diameter of the ice block.

[0034] Furthermore, the ice bucket 12 is rotatably connected to the centering column 21 via the bushing 13, and the propeller blades 14 are connected to the bushing 13 and the ice bucket 12 respectively. The aforementioned drive assembly drives the ice bucket 12 to rotate around the centering column 21, and the propeller blades 14 can squeeze the ice blocks to always tend towards the working surface 22, preventing the ice blocks from spinning empty inside the ice bucket 12 and improving the ice shaving efficiency.

[0035] The ice shaver includes a first blade holder 222 and a blade 223. The blade 223 passes through the ice outlet 221 and is fixedly connected to the bottom surface of the base 2 via the first blade holder 222. The blade 223 forms an angle C with the working surface 22, and the blade edge of the blade 223 extends beyond the working surface 22. The ice outlet 221 is arranged radially along the working surface. The blade 223 is inclined so that its blade passes through the ice outlet 221 and extends beyond the working surface 22. The blade edge of the blade 223 is relatively parallel to the working surface 22. When ice blocks slide along the working surface 22, they can impact the blade edge of the blade 223 and be cut by the blade 223 to form ice shavings and shaved ice. The first blade holder 222 is the assembly structure of the blade 223 on the base 2. The first blade holder 222 is a conventional technology that only needs to meet the installation and fixing requirements of the blade 223, so it will not be described in detail here.

[0036] The blade of the planer 223 has several fracture points 224 on its cutting edge, making the blade 223 serrated. Furthermore, the serrated cutting edge reduces the contact area between the planer 223 and the ice, which can increase the cutting force of the planer 223, making it easier for the planer 223 to cut and break the ice.

[0037] The crushing blade includes a second blade holder 225 and a plurality of crushing heads 226. The plurality of crushing heads 226 are fixedly connected to the bottom surface of the base 2 via the second blade holder 225, and the upper ends of the plurality of crushing heads 226 protrude from the working surface 22. The second blade holder 225 is used to mount the crushing heads 226 on the base 2. Specifically, the second blade holder 225 is provided with a plurality of crushing heads 226. The second blade holder 225 is fixed to the bottom surface of the base 2. The base 2 needs to be provided with some through holes so that the crushing heads 226 can pass through the base 2 and protrude from the working surface 22, so that when the ice block slides along the working surface 22, it can collide with the crushing heads 226.

[0038] The plurality of crushing heads 226 are arranged radially and spaced apart along the working surface 22. A first crushing blade 227 is provided on one side of each crushing head 226. The first crushing blade 227 is positioned opposite to the rotation direction of the ice bucket 12 and perpendicular to the working surface 22. It is understood that the spaced arrangement of the crushing heads 226 expands the effective range of the crushing blade on the working surface 22. When the ice bucket 12 rotates, the ice at the bottom of the ice bucket 12 moves linearly around the centering column 21 on the working surface 22, with the first crushing blade 227 facing the direction of the ice. Under the action of the propeller blade 14 and gravity, the ice has pressure tending towards the working surface 22. The linearly moving ice impacts the crushing head 226, and the first crushing blade 227 can scratch the surface of the ice or directly shatter it. As the ice continues to rotate and passes through the ice outlet 221, it is more easily broken or cut by the ice shaving blade to form slush.

[0039] The upper end of the shattering head 226 is provided with a second shattering blade 228, which can deepen the scratch and increase the probability of the shattering head 226 breaking ice, thereby improving the ice shaving efficiency.

[0040] The ice receiving assembly includes a base 3 and an ice cup 4. The ice cup 4 contains a stirrer 41, and a centering shaft 42 is located at its bottom. The lower end of the stirrer 41 is rotatably connected to the centering shaft 42. A rotatable drive shaft 23 passes through the centering column 21, and its upper end is fixedly connected to a bushing 13. The lower end of the drive shaft 23 passes through the base 2 and has an output interface. When the ice cup 4 is inserted into the base 3, it is paired with the ice outlet 221, and the upper end of the stirrer 41 is engaged with the output interface. It is understood that the base 3 has an open space, allowing the ice cup 4 to be inserted into the base 3 and paired with the ice outlet 221 on the base 2. Ice cubes in the ice bucket 12 are crushed and fall directly into the ice cup 4. Preferably, the ice cup 4 is equipped with a stirrer 41, and the ice bucket 12 can drive the stirrer 41 to rotate through the drive shaft 23, so that the ingredients can be added into the ice cup 4. As the ice slush is continuously poured in, the stirrer 41 mixes the ice slush with the ingredients in the ice cup 4, thereby making an ice slush beverage.

[0041] The base 3 has a spiral lifting groove 31 at its bottom, and the ice cup 4 has a spiral slider 43 at its bottom. The spiral slider 43 is inserted into the spiral lifting groove 31 and engages with it, thereby connecting the stirrer 41 inside the ice cup 4 to the output interface. The spiral lifting groove 31 is equivalent to a circular track with an opening on its side. When the ice cup 4 is placed into the base 3, the spiral slider 43 is inserted into the spiral lifting groove 31 along the opening and engages with it. The ice cup 4 is rotated at a certain angle, and through the threaded transmission between the spiral slider 43 and the spiral lifting groove 31, the ice cup 4 is lifted so that its upper end contacts the connecting piece on the bottom surface of the base 2, and the upper end of the stirrer 41 engages with the output interface to achieve a transmission connection.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
