Description

Technical Field

[0001] This application relates to the field of table tennis cabinet manufacturing technology, and in particular to a barrel-type table tennis cabinet air duct structure for maintaining temperature uniformity. Background Technology

[0002] Ice cream scooping cabinets are commercial refrigeration equipment specifically designed for storing and displaying ice cream and facilitating scooping operations. They are widely used in various commercial venues such as ice cream shops, dessert shops, cafes, supermarkets, and restaurants.

[0003] With the continuous development of the frozen dessert industry and the upgrading of consumption, consumers have placed higher demands on the quality, taste, and purchasing experience of ice cream. To meet market needs, ice cream scooping cabinets have emerged. Their design fully considers the storage characteristics of ice cream and the convenience of scooping. They typically employ professional refrigeration systems that can precisely control the internal temperature between -18℃ and -22℃. This temperature range effectively ensures that the ice cream is in its optimal firmness, facilitating scooping and maintaining its good taste.

[0004] Currently, ice cream scooping cabinets still have two prominent problems in temperature control: First, it is difficult to ensure temperature uniformity between adjacent ice cream buckets inside the cabinet, which can easily lead to differences in the hardness of ice cream in different buckets; Second, along the height of the bucket, there is a significant temperature gradient between the upper and lower layers inside the cabinet, resulting in uneven texture of ice cream in the upper and lower parts of the same bucket. This not only increases the difficulty of scooping but may also affect the taste of the product due to local melting or overfreezing. These uneven temperature distribution problems not only reduce operational efficiency but also pose a challenge to the stability of ice cream quality. Utility Model Content

[0005] This device provides an air duct structure for a barrel-type ball-playing cabinet that maintains a uniform temperature. The specific implementation method is as follows: A cooling duct structure for a barrel-type sports cabinet that maintains a uniform temperature includes: The cabinet has several ball-playing drums arranged in a matrix inside the refrigerator compartment, and the top of the refrigerator compartment is a lift-up door; The cold storage room is divided into upper and lower layers by partitions. The bottom of the ball-hitting drum is located on the lower layer, and the top opening of the ball-hitting drum is located on the upper layer. The upper layer is divided into several sub-cold storage spaces by the central beam between each longitudinally adjacent ball-hitting drum. The air supply structure located in the lower layer of the cold storage compartment has a hollow central beam with second air intake grilles on both sides. The air outlet of the air supply structure is connected upward to the hollow part of the central beam. The refrigeration unit cools the cold storage compartment, and the air supply structure and central beam deliver the cold air from the lower layer of the cold storage compartment to each sub-cold storage space to maintain a balanced temperature.

[0006] Based on the above technical solutions, the structural design of the cold storage space effectively isolates the longitudinally adjacent ball buckets by setting up a central beam component. A hollow central beam structure is also adopted to create a dedicated channel for cold air circulation. To further improve the temperature stability of each sub-cold storage space, an air supply structure is designed. This structure guides the low-temperature cold air from the lower layer into the hollow part of the central beam. After entering the hollow channel, the cold air is evenly distributed to each sub-cold storage space along the longitudinal extension direction of the central beam. Through this "lower layer cooling - hollow center cooling - zoned cooling" design, the vertical temperature stratification problem commonly found in traditional cold storage spaces is effectively solved. This ensures that the temperature in each sub-cold storage space remains within a set range, with the temperature difference between the upper and lower areas controlled within a very small range. Ultimately, this achieves a high degree of vertical temperature balance in each sub-cold storage space, providing a stable temperature guarantee for the storage quality of items inside the ball buckets.

[0007] Preferably, the refrigeration unit is located below the cabinet, and the evaporator coil of the refrigeration unit is arranged around the outer perimeter of the refrigerator.

[0008] Preferably, the air supply structure includes a mounting base located on the lower layer of the cold storage compartment, and a fan is provided on the top of the mounting base.

[0009] Preferably, the central beam has a U-shaped structure, and its top abuts against the upper lifting door via an abutment block.

[0010] Based on the above technical solutions, the refrigeration unit is a conventional technology in this field. Through the coordinated work of the compressor, condenser and evaporator components, the refrigerant is compressed, condensed and throttled, and then efficient heat exchange is completed in the evaporator to continuously generate low-temperature cold air.

[0011] Preferably, the partition has an installation through hole for inserting the ball barrel, and the two ends of the partition have a first air intake grille facing upwards.

[0012] Preferably, the first air intake grille has barbs at both ends, which are engaged with the bottom of the second air intake grille.

[0013] Preferably, the first air intake grille and the second air intake grille are arranged in a staggered manner on the upper layer of the refrigerator compartment.

[0014] Based on the above technical solutions, by setting the first air intake grille and the second air intake grille in a staggered manner, the cold air is divided into two streams and enters the sub-refrigeration space along channels at different heights, avoiding direct airflow collision, reducing pressure loss, ensuring that the cold air is delivered in a smoother and more stable state, and improving the overall cooling efficiency. The staggered design ensures that the openings of the two grilles do not overlap, and the cold air will form a "three-dimensional diffusion" in the sub-refrigeration space, rather than a "planar coverage" with the grilles flush with each other.

[0015] Preferably, the upper side wall of the cold storage compartment is provided with a positioning block, and the barbs of the end partition are engaged with the positioning block.

[0016] Preferably, each air supply structure is arranged at the center of the cross of each ball-playing tube in a matrix shape.

[0017] Based on the above technical solutions, from the perspective of airflow coverage efficiency, the matrix-distributed air supply structure forms interconnected cold air coverage areas. The cross-shaped center distance between two adjacent air supply structures is exactly matched with the matrix spacing of the ball pit, so that the cold air coverage range of a single air supply structure can form a cold air coverage layer with the coverage range of the surrounding air supply structures in the entire plane.

[0018] In summary, this application includes the following beneficial technical effects: 1. This utility model isolates each longitudinally adjacent ball bucket from each other through a central beam. At the same time, the central beam is hollow, and the cold air from the lower part of the cold storage compartment is sent to each sub-cold storage space through the hollow part of the central beam by means of the air supply structure, so as to maintain the vertical temperature balance of each sub-cold storage space. 2. This utility model has a simple structure. By setting the first air intake grille on the partition, not only is the assembly of the partition on the middle beam and positioning block realized, but the combination with the second air intake grille also realizes the staggered introduction of cold air. 3. This utility model arranges each air supply structure at the center of the cross of each ball bucket in a matrix, so that the cold air coverage of a single air supply structure can form a cold air coverage layer with the coverage of the surrounding air supply structures in the entire plane.
