Description

Technical Field

[0001] This utility model relates to the field of ice maker technology, and in particular to an ice maker structure with ultrasonic defoaming function. Background Technology

[0002] In modern life and business settings, ice makers, as key equipment for providing low-temperature cold sources and ensuring the taste of beverages, are widely used in homes, restaurants, supermarkets, and other fields. However, as users' demands for ice quality, ice-making efficiency, and the diversity of ice shapes continue to increase, the defoaming technology of existing ice makers is gradually revealing its limitations, failing to meet the needs of demanding application scenarios.

[0003] Currently, ice makers primarily employ dynamic level control defoaming and continuous water flow defoaming. Dynamic level control defoaming uses a mechanical device (such as a pressure plate driven by a telescopic motor) to periodically squeeze the water supply hose, causing the water level entering the ice-making grid to fluctuate. This fluctuation disrupts the surface tension of the water, causing existing or soon-to-be-formed bubbles to burst and escape. Continuous water flow defoaming mainly involves a water pump continuously and slowly injecting water into the ice-making tank during ice making, keeping the water in a flowing state. The flowing water carries away dissolved air and small bubbles, preventing them from freezing. Simultaneously, the one-way freezing effect pushes impurities and bubbles towards the unfrozen water and carries them away, ultimately forming transparent ice. Regardless of the defoaming technology used, high precision control and component reliability are required. Mechanical fatigue can lead to a decrease in effectiveness. Furthermore, due to limitations in the defoaming structure, ice-making efficiency is relatively low, the shape and structure of the ice blocks are not diverse, and the quality of the ice blocks cannot be effectively guaranteed.

[0004] Therefore, it is necessary to design an ice maker structure with ultrasonic defoaming function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an ice maker structure with ultrasonic defoaming function. This invention effectively removes air bubbles from the liquid through an ultrasonic defoaming transducer module, ensuring the quality of the ice cubes. At the same time, the inclusion of a flip motor and a drive motor facilitates the removal of the ice cubes after ice making.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ice maker structure with ultrasonic defoaming function includes an ice maker box, which includes a square frame. The lower end of the square frame is provided with a base plate. Multiple partitions are provided inside the square frame, and the multiple partitions are perpendicular to each other. An ultrasonic defoaming transducer module is installed on the base plate. The ultrasonic defoaming transducer module includes an ultrasonic defoaming transducer body, a base, and a control board. The base plate and the square frame are rotatably connected by two hinges.

[0007] Preferably, two fixing blocks are fixedly connected to the right side of the square frame, and a first connecting rod is rotatably connected to the adjacent sides of the two fixing blocks. The adjacent sides of the two first connecting rods are fixedly connected to the pivot of the corresponding hinge. The adjacent sides of the pivot of the two hinges are jointly fixedly connected to a second connecting rod. A drive motor is installed on the fixing block located on the rear side, and the end of the output shaft of the drive motor is fixedly connected to the first connecting rod located on the rear side.

[0008] Preferably, a sealing soft adhesive is provided between the base plate and the square frame, and the sealing soft adhesive is fixedly connected to the base plate. The sealing soft adhesive is U-shaped.

[0009] Preferably, it also includes a fixed frame, the square frame is located inside the fixed frame, and rotating rods are fixedly connected to both the left and right sides of the square frame. The opposite sides of the two rotating rods are rotatably connected to the inner wall of the fixed frame. A flip motor is installed on the left side of the fixed frame, and the end of the output shaft of the flip motor is fixedly connected to the rotating rod located on the left side.

[0010] Preferably, mounting rings are fixedly connected to both the upper and lower sides of the fixed frame.

[0011] Preferably, the inner walls of the plurality of partitions are embedded with heating wires, and the plurality of partitions are made of iron sheets.

[0012] Compared with existing technologies, the advantages of this device are: Compared with existing technologies, this device achieves non-contact defoaming through an ultrasonic defoaming transducer module. The core components have no mechanical wear, and the ultrasonic energy is directionally transmitted to the water through the base plate. The continuous or intermittent working mode can be set through the control board to ensure long-term stable defoaming effect, unaffected by component aging or operating condition fluctuations. Compared with existing technologies, this device directly breaks bubbles with ultrasound or drives bubbles to float and burst, which can completely eliminate bubbles in water. The resulting ice blocks are highly transparent, bubble-free, and have a significantly increased density, thus extending the melting time. At the same time, the ice removal method, which involves opening and closing the bottom plate or flipping the ice tray, facilitates the removal of ice blocks. Compared with existing technologies, the ultrasonic defoaming module of this device can be carried out simultaneously with the condensation process, without waiting for natural defoaming. Moreover, the defoaming function is independent of the condensation system, and the condenser can be optimized according to the ice-making efficiency to improve the condensation rate. At the same time, ultrasonic defoaming directly and quickly eliminates bubbles, saving the redundant time of bubble removal in traditional technologies and significantly shortening the total ice-making cycle. The efficiency advantage is even more obvious in water bodies with high gas content or high-load ice-making scenarios. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3An ice maker structure with ultrasonic defoaming function includes an ice maker box, which comprises a square frame 1 made of food-grade 304 stainless steel. The inner wall surface of the frame 1 is polished to a roughness Ra≤0.8μm, preventing chemical reactions between water and metal surfaces that could affect water quality and reducing water adhesion to the sidewalls for easier ice removal. A base plate 4, also made of food-grade 304 stainless steel with a thickness of 2-3mm, is provided at the lower end of the square frame 1. The structure is strong enough to support the weight of the water and the installation of the ultrasonic defoaming transducer module 3, while also possessing excellent ultrasonic wave conduction performance to ensure efficient energy transfer to the water. The square frame 1 contains multiple partitions 2, each with an embedded heating wire on its inner wall. When energized, the heating wire rapidly heats the surface of the partitions 2, melting the ice layer and preventing ice from sticking to them. All partitions 2 are made of iron sheets and are perpendicular to each other. The number and spacing of the partitions 2 can be flexibly adjusted according to the required ice size; for example, three sets of horizontal partitions can be used. The partition and three sets of longitudinal partitions can form 16 square ice-making grids with a side length of 3cm to meet the needs of different scenarios. An ultrasonic defoaming transducer module 3 is installed on the base plate 4. The ultrasonic defoaming transducer module 3 can be installed individually in the center of the base plate 4, or one ultrasonic defoaming transducer module 3 can be installed at the bottom of each ice-making grid. The ultrasonic defoaming transducer module 3 includes an ultrasonic defoaming transducer body, a base, and a control board. The working frequency of the ultrasonic defoaming transducer body is set to 20-40kHz, and the output power is 100-200W. The power can be adjusted according to the gas content of the water. The base is made of ABS engineering plastic and has heat dissipation texture on the surface to disperse the heat generated by the transducer during operation. The control board integrates an MCU controller (model STM32F103), a power drive chip (model IR2110), and a button module. The continuous defoaming or intermittent defoaming mode can be preset through the button module. In the intermittent defoaming mode, the working interval can be adjusted within the range of 10-60s.

[0017] The base plate 4 and the square frame 1 are rotatably connected by two hinges 12. Two fixing blocks 9 are fixedly connected to the right side of the square frame 1. The adjacent sides of the two fixing blocks 9 are rotatably connected to the first connecting rods 10. The adjacent sides of the two first connecting rods 10 are fixedly connected to the pivot of the corresponding hinge 12. The hinge 12 includes a fixed piece, a rotating piece, and a pivot. The rotating piece is fixedly connected to the pivot. The fixed piece is installed on the square frame 1 by multiple bolts. The rotating piece is fixedly connected to the base plate 4 by multiple bolts. The adjacent sides of the pivots of the two hinges 12 are fixedly connected to the second connecting rod 11. A drive motor 13 is installed on the fixing block 9 located on the rear side. The drive motor 13 is a DC geared motor. The end of the output shaft of the drive motor 13 is fixedly connected to the first connecting rod 10 located on the rear side.

[0018] The base plate 4 and the square frame 1 are provided with a sealing soft rubber. The sealing soft rubber is made of food-grade silicone rubber, which has good elasticity and sealing performance. The sealing soft rubber is fixedly connected to the base plate 4. The sealing soft rubber is U-shaped, with its inner edge flush with the inner wall of the square frame 1 and its outer edge flush with the edge of the base plate 4. This not only ensures the sealing of the ice-making cavity and prevents water leakage, but also blocks the transmission of ultrasonic energy to the side wall of the square frame 1, avoids energy loss, and ensures that the ultrasonic energy is concentrated on the water.

[0019] The device also includes a fixed frame 7, with a square frame 1 located inside the fixed frame 7. Rotating rods 8 are fixedly connected to both the left and right sides of the square frame 1. The opposite sides of the two rotating rods 8 are rotatably connected to the inner wall of the fixed frame 7. A flip motor 5 is installed on the left side of the fixed frame 7. The output shaft end of the flip motor 5 is fixedly connected to the rotating rod 8 located on the left side. Mounting rings 6 are fixedly connected to both the upper and lower sides of the fixed frame 7. The inner wall of the mounting rings 6 is provided with internal threads, and the entire device can be fixed to the frame of the ice maker by bolts. The installation height can be flexibly adjusted according to the internal space of the ice maker.

[0020] The functional principle of this utility model can be explained through the following operation: First, structural assembly and initial preparation are carried out. The ultrasonic defoaming transducer module 3 is installed on the base plate 4 of the ice maker (it can be installed on the upper end, lower end or embedded in the base plate 4), ensuring that the module and the base plate 4 are tightly fitted to ensure energy transmission. Then, the base plate 4 and the square frame 1 are rotatably connected by two hinges 12. A U-shaped sealing soft rubber is fixed at the connection between the base plate 4 and the square frame 1 to ensure the sealing of the ice-making cavity and to block the transmission of ultrasonic energy to the side wall of the square frame 1, thus avoiding energy loss. The fixing frame 7 is fitted on the outside of the square frame 1, and the entire device is installed in the ice maker through the fixing frame 7, so that the condenser surrounds the ice maker. Finally, the working mode is preset by the control board of the ultrasonic defoaming transducer module 3 to prepare for the subsequent ice-making process.

[0021] Next, the device is started to enter the water injection and synchronous condensation and defoaming operation stage. An appropriate amount of water is injected into the ice-making grid cavity formed by the partition 2 within the square frame 1. After the water level reaches the preset height, the condenser surrounding the ice-making grid is activated. Utilizing the advantage of the condenser's surrounding layout, the water in the ice-making grid is quickly cooled and condensed, gradually pushing the water closer to the freezing point. During this process, the ultrasonic defoaming transducer module 3 on the base plate 4 is simultaneously activated. The module transmits ultrasonic energy directionally to the water in the cavity through the base plate 4: on the one hand, the ultrasonic waves directly... The ultrasonic waves act on the bubbles in the water, using high-frequency vibrations to break them up quickly. On the other hand, the ultrasonic waves drive the tiny bubbles in the water that have not been broken to rise faster until they float to the surface and come into contact with the air, where they automatically burst, completely eliminating the bubbles in the water. Throughout the process, the sealing soft rubber between the bottom plate 4 and the square frame 1 effectively isolates the energy from being conducted to the side wall of the square frame 1, ensuring that the ultrasonic energy is concentrated on the water and guaranteeing the defoaming effect. At the same time, condensation and defoaming occur simultaneously, eliminating the need to wait for natural defoaming and significantly shortening the preparation time before ice making.

[0022] Finally, the ice-making and ice-removal process begins. The condenser and ultrasonic defoaming transducer module 3 continue to run until the water in the ice tray is completely frozen into ice. At this point, ice removal can be accomplished in two ways: The first way is to start the drive motor 13 located on the rear fixed block 9. The output shaft of the drive motor 13 drives the rear first connecting rod 10 to rotate. The rear first connecting rod 10 drives the second connecting rod 11 to rotate through the pivot of the hinge 12, which in turn drives the front first connecting rod 10 to rotate synchronously. This causes the hinge 12 to cause the bottom plate 4 to flip downwards and open. Then, the ice is peeled off and discharged from the ice tray through the preset peeling structure. The second way is to start the flip motor 5 on the left side of the fixed frame 7. The output shaft of the flip motor 5 drives the left rotating rod 8 to rotate. The rotating rod 8 causes the square frame 1 to adjust its angle within the fixed frame 7, allowing the ice to tilt and be discharged from the top of the ice tray. Both ice removal methods can achieve efficient collection of ice and complete one ice-making cycle.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
