Description

Technical Field

[0001] This utility model relates to the technical field of ice extrusion molding for ice makers, specifically to an ice extrusion head for ice makers and its evaporator. Background Technology

[0002] The evaporator has two tanks, an inner and an outer. The inner tank acts as an ice-making tank, and a space between the outer and inner tanks allows for the flow of the heat exchange medium. When the heat exchange medium exchanges heat with the water in the inner tank, ice is produced. The inner tank has an ice-extruding head at one end, and a rotating ice-squeezing screw inside. As the screw rotates, it conveys the ice towards the extruding head, extruding it into ice blocks. During extrusion, the scraped ice is distributed through various outlet holes on the extruding head. However, due to the randomness of the ice-scraping action of the ice blade, the ice blocks cannot be evenly distributed into all the outlet holes. Specifically:

[0003] Excessive ice buildup in some ice outlets leads to excessive extrusion pressure, resulting in overly hard extruded ice that affects quality.

[0004] Insufficient ice volume at some ice outlets → Insufficient extrusion pressure → Ice blocks cannot be formed, resulting in broken ice and reduced ice dispensing efficiency. Utility Model Content

[0005] This invention proposes an ice extrusion head and its evaporator for an ice maker. The ice extrusion head, by incorporating an ice quantity extrusion adjustment section, can dynamically adjust the uniformity of ice distribution. During the extrusion process, when excessive ice accumulates in some outlet channels due to the random scraping action of the ice blade screw, the ice can be transferred through the ice quantity extrusion adjustment section to adjacent outlet channels with less accumulated ice, thereby balancing the extrusion pressure of each outlet channel. This design effectively avoids the problem of excessively hard or broken ice caused by uneven extrusion pressure, significantly improving ice quality and efficiency. The interconnectedness of the ice quantity extrusion adjustment section allows ice to naturally transfer and distribute to areas with lower pressure, ensuring that the extrusion amount of each outlet channel tends to be consistent, thus extruding uniformly shaped ice blocks. This structure is simple and practical, achieving automatic adjustment without the need for an additional power unit, reducing the energy consumption and complexity of the ice maker.

[0006] An ice extrusion head for an ice maker designed for this purpose includes an ice extrusion head body having a plurality of ice outlet channels. Each ice outlet channel has a connected input end and an output end. The ice extrusion head body is provided with an ice quantity extrusion adjustment section for connecting the input end of adjacent ice outlet channels. During the ice extrusion process, ice is transferred and distributed from the ice outlet channel with a large amount of ice accumulation to the adjacent ice outlet channel with a small amount of ice accumulation through the ice quantity extrusion adjustment section, so that each ice outlet channel extrudes uniform ice blocks.

[0007] The ice quantity extrusion adjustment section is located near the input end of the ice outlet channel.

[0008] An ice extrusion adjustment section is provided between the sides of each pair of adjacent ice outlet channel input ends, and the ice extrusion adjustment section is connected to the adjacent ice outlet channel input ends on both sides.

[0009] Each ice outlet channel is equipped with a closed surface connected to the ice quantity extrusion adjustment section. The closed surface is annular and forms an annular ice outlet section of the ice outlet channel. The annular ice outlet sections of each ice outlet channel are kept separate from each other through the closed surface.

[0010] The closed side is provided with a notch at the ice outlet channel input end to form an ice quantity extrusion adjustment section, so that every two adjacent ice outlet channel input ends are connected, thereby realizing the distribution and adjustment of ice quantity during the ice extrusion process of the ice extrusion head body.

[0011] The notch is concave arc-shaped, and ice is transferred from the ice outlet channel with a large amount of ice accumulation to the adjacent ice outlet channel with a smaller amount of ice accumulation along the concave arc-shaped notch.

[0012] The plurality of ice outlet channels are arranged circumferentially on the ice extrusion head body.

[0013] The ice outlet channel is equipped with a guide structure at its input end for compressing and accumulating ice.

[0014] The ice outlet channel has inclined surfaces on both sides of its input end, and the distance L between the two sides of the input end of the ice outlet channel gradually decreases towards the output end of the ice outlet channel to form a guide structure for squeezing and accumulating ice.

[0015] An ice maker evaporator designed for this purpose includes an evaporator body and an ice blade screw rotatably disposed within the evaporator body. The evaporator body is provided with an ice extrusion head for the ice maker, and the ice blade screw transports ice from the evaporator body to the ice extrusion head by rotating on its own.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] The ice extrusion head of the ice maker features an ice quantity extrusion adjustment section that dynamically regulates the uniformity of ice distribution. During extrusion, if excessive ice accumulates in some outlet channels due to the random scraping action of the ice blade screw, the ice can be transferred through the ice quantity extrusion adjustment section to adjacent outlet channels with less accumulated ice, thus balancing the extrusion pressure across all outlet channels. This design effectively avoids problems such as excessively hard ice or broken ice caused by uneven extrusion pressure, significantly improving ice quality and efficiency. The interconnectedness of the ice quantity extrusion adjustment section allows ice to naturally transfer and distribute to areas with lower pressure, ensuring a consistent extrusion volume in each outlet channel, resulting in uniformly shaped ice blocks. This structure is simple and practical, achieving automatic adjustment without the need for an additional power unit, reducing the energy consumption and complexity of the ice maker.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0023] See Figures 1-3 An ice extrusion head for an ice maker includes an ice extrusion head body 2 with a plurality of ice outlet channels 1. Each ice outlet channel 1 has a connected input end and an output end. The ice extrusion head body 2 is provided with an ice quantity extrusion adjustment section 3 for connecting the input end of adjacent ice outlet channels 1. During the ice extrusion process, ice is transferred from the ice outlet channel 1 with a large amount of ice accumulation to the adjacent ice outlet channel 1 with a small amount of ice accumulation through the ice quantity extrusion adjustment section 3, so that each ice outlet channel 1 is extruded into a uniform ice block.

[0024] The ice extrusion head 2 of the ice maker, through the ice quantity extrusion adjustment section 3, can dynamically adjust the uniformity of ice distribution. During the extrusion process, when excessive ice accumulates in some ice outlet channels 1 due to the random scraping action of the ice blade screw 6, the ice can be transferred through the ice quantity extrusion adjustment section 3 to adjacent ice outlet channels 1 with less accumulated ice, thereby balancing the extrusion pressure of each ice outlet channel 1. This design effectively avoids the problem of excessively hard or broken ice caused by uneven extrusion pressure, significantly improving ice quality and efficiency. The interconnecting function of the ice quantity extrusion adjustment section 3 allows ice to be naturally transferred and distributed to areas with lower pressure, ensuring that the extrusion amount of each ice outlet channel 1 tends to be consistent, thus forming uniform ice blocks. This structure is simple and practical, achieving automatic adjustment without additional power devices, reducing the energy consumption and complexity of the ice maker.

[0025] The ice quantity extrusion adjustment section 3 is located near the input end of the ice outlet channel 1.

[0026] Placing the ice extrusion adjustment section 3 near the input end of the ice outlet channel 1 allows for a more direct response to uneven ice distribution. Since the input end of the ice outlet channel 1 is where the ice initially enters, placing the ice extrusion adjustment section 3 here allows for rapid detection of pressure differences and real-time ice distribution through the connection of two adjacent ice outlet channels 1. This layout optimizes the uniform distribution of ice while further ensuring uniform density of the extruded ice, thus improving overall ice-making quality.

[0027] An ice quantity extrusion adjustment section 3 is provided between the sides of the input ends of each pair of adjacent ice outlet channels 1. The two sides of the ice quantity extrusion adjustment section 3 are respectively connected to the input ends of the adjacent ice outlet channels 1.

[0028] An ice extrusion adjustment section 3 is provided between the input ends of every two adjacent ice outlet channels 1, enabling dynamic distribution of ice between them. This design expands the adjustment range; regardless of the randomness of the ice scraping action of the ice blade screw 6, ice is transferred from the ice outlet channel 1 with a larger ice accumulation to the adjacent ice outlet channel 1 with a smaller ice accumulation through the ice extrusion adjustment section 3. The double-sided interconnected structure of the ice extrusion adjustment section 3 enhances the dynamic distribution of ice. Simply put, the ice outlet channel 1 with a larger ice accumulation receives a smaller subsequent ice allocation, while the ice outlet channel 1 with a smaller ice accumulation receives a larger subsequent ice allocation, ensuring that the ice extrusion head body 2 maintains stable ice uniformity even when the ice blade screw 6 is randomly scraping ice.

[0029] Each ice outlet channel 1 is provided with a closed surface 1.1 connected to the ice quantity extrusion adjustment section 3. The closed surface 1.1 is annular and forms an annular ice outlet section 1.2 of the ice outlet channel 1. The annular ice outlet sections 1.2 of each ice outlet channel 1 are kept separate from each other through the closed surface 1.1.

[0030] By setting up a closed surface 1.1 and an annular ice outlet section 1.2, the independence of the ice blocks during extrusion molding is ensured, while the ice quantity distribution between adjacent ice outlet channels 1 is achieved through the ice quantity extrusion adjustment section 3. The annular structure of the closed surface 1.1 prevents ice from interfering with each other in the ice outlet section 1.2, ensuring that each annular ice outlet section 1.2 of the ice outlet channel 1 forms a complete and uniform ice block. At the same time, the ice quantity extrusion adjustment section 3 allows for ice quantity distribution adjustment at the input end of the ice outlet channel 1, while maintaining separation at the output end of the ice outlet channel 1, thus balancing distribution flexibility and molding stability.

[0031] The side of the closed surface 1.1 is provided with a notch 3.1 at the input end of the ice outlet channel 1 to form an ice quantity extrusion adjustment section 3, so that every two adjacent input ends of the ice outlet channel 1 are connected, thereby realizing the distribution and adjustment of ice quantity during the ice extrusion process of the ice extrusion head body 2.

[0032] The design of notch 3.1 clarifies the specific structure of the ice extrusion regulating section 3. As a path connecting adjacent ice outlet channels 1, it guides the ice to naturally transfer and distribute from the high-pressure zone to the low-pressure zone. The shape and size of notch 3.1 optimize the ice transfer efficiency, preventing blockages or poor distribution. The discontinuous design of the closed surface 1.1 at notch 3.1 maintains the isolation between adjacent ice outlet channels 1 while providing sufficient connectivity to ensure efficient regulation. This structure is simple and easy to manufacture.

[0033] The notch 3.1 is concave arc-shaped, and ice is transferred from the ice outlet channel 1 with a large amount of ice accumulation to the adjacent ice outlet channel 1 with a small amount of ice accumulation along the concave arc-shaped notch 3.1.

[0034] The concave arc-shaped notch 3.1 can guide ice transfer more smoothly, and its arc-shaped edge reduces the frictional resistance during ice transfer and distribution, making ice distribution more natural and efficient.

[0035] The plurality of ice outlet channels 1 are arranged circumferentially on the ice extrusion head body 2.

[0036] The ice outlet channel 1 is provided with a guide structure 4 for squeezing and accumulating ice at the input end.

[0037] The ice outlet channel 1 has inclined surfaces on both sides of its input end, and the distance L between the two sides of the input end of the ice outlet channel 1 gradually decreases towards the output end of the ice outlet channel 1 to form a guide structure 4 for squeezing and accumulating ice.

[0038] The guide structure 4 further optimizes the ice gathering and extrusion process, making the ice more compact and uniform before entering the ice outlet section of the ice outlet channel 1. The guide structure 4 can guide the ice to smoothly transition to the input end of the ice outlet channel 1, reducing the risk of blockage, while enhancing the extrusion pressure to ensure the hardness and integrity of the ice block after it is formed.

[0039] The inclined guide structure 4, with its gradually decreasing spacing L, creates a natural compression and aggregation effect, gradually compressing the ice during transport and increasing its density. This structure avoids the problem of ice breaking due to sudden pressure, while optimizing the ice's output path, allowing it to enter the ice outlet channel 1 more smoothly. The angle and length of the inclined surface can be adjusted according to the characteristics of the ice to adapt to different working conditions, enhancing the adaptability of the ice extrusion head.

[0040] See Figure 4 An ice maker evaporator includes an evaporator body 5 and an ice blade screw 6 rotatably disposed within the evaporator body 5. The evaporator body 5 is provided with an ice extrusion head for the ice maker, and the ice blade screw 6 transports ice from the evaporator body 5 to the ice extrusion head by rotating on its own.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
