Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a convenient assembly structure of a refrigeration evaporator. Background Art

[0002] A smoothie maker (also called a snow melting machine) is a device capable of making smoothies. For example, a snow melting machine disclosed in an invention application with Chinese patent number CN202410556731.8 stores a liquid food in a storage cover, and an evaporator is located in the storage cover. During use, the cold on the evaporator cools the liquid food so that an ice crystal mixture is formed on the outer wall of the evaporator. At the same time, a driving motor drives a scraper to rotate on the outer wall of the evaporator and stir the formed ice crystal mixture to form smoothies.

[0003] The existing such evaporators mainly consist of an inner barrel, a copper tube wound around the outer periphery of the inner barrel, and an outer barrel sleeved outside the inner barrel and the copper tube. At the same time, in order to better transfer cold, the inner barrel, the copper tube, and the outer barrel rely on each other. However, the outer walls of the outer barrel and the inner barrel both extend linearly, resulting in difficulty in aligning the inner wall of the outer barrel with the outer walls of the inner barrel and the copper tube when the outer barrel is assembled by sleeving, causing assembly difficulties. Even if the outer barrel can be aligned with the inner barrel and the copper tube, it is very difficult for the outer barrel to be slidably sleeved, and even if the outer barrel can be slidably sleeved on the inner barrel and the copper tube, wear will occur due to the similar inner and outer dimensions of each other. Therefore, it is necessary to further improve. Content of the Utility Model

[0021] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model 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 connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0022] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1 - 5, The convenient assembly structure of this refrigeration evaporator includes an inner barrel 40, an outer barrel 50 and a connecting pipe 60. The inner barrel 40 is cylindrical, and the outer wall size thereof is tapered with the front being smaller and the rear being larger. The connecting pipe 60 is spirally wound around the outer wall of the inner barrel 40 and is arranged in a tapered shape with the front being smaller and the rear being larger after winding. The outer barrel 50 is cylindrical, and the inner wall size thereof is tapered with the front being smaller and the rear being larger. There is an outer barrel rear opening 50.1 at the rear end of the outer barrel 50, and the size of the outer barrel rear opening 50.1 is larger than the front end size of the connecting pipe 60 after winding. The outer barrel 50 is aligned with the front ends of the inner barrel 40 and the connecting pipe 60 through the outer barrel rear opening 50.1 and is sleeved around the outer periphery of the inner barrel 40 and the connecting pipe 60.

[0024] In this embodiment, the outer walls of the inner barrel 40 and the outer barrel 50 are respectively arranged in a tapered shape with the front being smaller and the rear being larger, and the connecting pipe 60 is spirally wound around the outer wall of the inner barrel 40, so that a tapered arrangement with the front being smaller and the rear being larger is also formed on the outer periphery of the connecting pipe 60 after winding. Since the size of the outer barrel rear opening 50.1 at the rear end of the outer barrel 50 is larger than the front end size of the connecting pipe 60 after winding, during assembly, the outer barrel rear opening 50.1 can conveniently align with the front ends of the inner barrel 40 and the connecting pipe 60 and can be assembled around the outer periphery of the inner barrel 40 and the connecting pipe 60 by means of sliding sleeving, thereby effectively improving the assembly convenience of the inner barrel 40, the outer barrel 50 and the connecting pipe 60. In addition, during the sliding sleeving process of the outer barrel 50, a dimensional difference will be formed with the outer wall of the connecting pipe 60 and there will be no mutual friction problem, thereby effectively avoiding the wear between the outer barrel 50 and the connecting pipe 60 during sliding sleeving, improving the service life of the product, and at the same time reducing the problem of displacement of the connecting pipe 60 after assembly caused by external force and ensuring the accuracy of the assembly position of the connecting pipe 60.

[0025] The inner wall of the connecting pipe 60 and the outer wall of the inner barrel 40 rely on each other, and / or the outer wall of the connecting pipe 60 and the inner wall of the outer barrel 50 rely on each other.

[0026] In this embodiment, the inner wall and the outer wall of the connecting pipe 60 rely on the outer wall of the inner barrel 40 and the inner wall of the outer barrel 50 respectively, so as to better enable the cold quantity to be transferred on the outer wall of the outer barrel 50.

[0027] An outer barrel rear outer extension edge 50.2 extends around the outer barrel rear opening 50.1, and a plurality of outer barrel rear fixing holes 50.3 are arranged at intervals on the outer barrel rear outer extension edge 50.2. Thereby, fixing members can be arranged on the plurality of outer barrel rear fixing holes 50.3 to realize the fixation of the outer barrel 50, and further complete the installation of the entire refrigeration evaporator.

[0028] Inside the inner barrel 40, a partition barrel 40.1 is provided, and the first inner barrel cavity 40.2 and the second inner barrel cavity 40.3 which are independent of each other are separated by the partition barrel 40.1. The front end of the first inner barrel cavity 40.2 is sealed, and the rear end is provided with a rear opening 40.4 of the first inner barrel cavity. The front end and the rear end of the second inner barrel cavity 40.3 are respectively provided with a front opening 40.5 and a rear opening 40.6 of the second inner barrel cavity.

[0029] The connecting pipe 60 is provided with a connecting pipe inlet 60.1 and a connecting pipe outlet 60.2. The connecting pipe inlet 60.1 is located at the rear end of the inner barrel 40 and extends outward through the rear opening 40.4 of the first inner barrel cavity and the rear opening 50.1 of the outer barrel. The front end of the connecting pipe 60 is bent around and positioned on the front opening 40.5 of the second inner barrel cavity, and the connecting pipe outlet 60.2 extends outward toward the rear opening 40.6 of the second inner barrel cavity and the rear opening 50.1 of the outer barrel.

[0030] In this embodiment, the connecting pipe inlet 60.1 and the connecting pipe outlet 60.2 extend outward respectively and are communicated with the refrigerant end respectively, so that the refrigerant enters the connecting pipe 60 through the connecting pipe inlet 60.1 and is discharged from the connecting pipe outlet 60.2. At the same time, since the connecting pipe 60 is spirally wound, it is beneficial to increase the evaporation area, not only making the refrigeration more uniform and rapid, improving the evaporation efficiency, but also being more energy-saving and efficient.

[0031] The front end of the inner barrel 40 is provided with a front end cover plate 70. The front end of the connecting pipe 60 is positioned on the front end cover plate 70. The front end cover plate 70 is provided with a front end cover plate opening 70.1, and the front end cover plate opening 70.1 corresponds to the front opening 40.5 of the second inner barrel cavity. The front end cover plate 70 and / or the inner barrel 40 are provided with a bending positioning groove 71. The front end of the connecting pipe 60 is bent toward the front end cover plate opening 70.1 and the front opening 40.5 of the second inner barrel cavity, and its bending position is positioned on the bending positioning groove 71.

[0032] In this embodiment, the front end cover plate 70 and the inner barrel 40 are both provided with bending positioning grooves 71. Using the front end cover plate 70 to position the front end of the connecting pipe 60 wound around can avoid the problem that the front end of the connecting pipe 60 is displaced after assembly. At the same time, using the bending position of the connecting pipe 60 can be positioned on the bending positioning groove 71, which not only avoids damage to the bending position of the connecting pipe 60, but also further improves the stability of the assembly position of the front end of the connecting pipe 60.

[0033] A rear cover plate 80 is provided at the rear end of the inner barrel 40. The rear cover plate 80 covers the rear opening 40.6 of the second inner barrel cavity and the rear opening 50.1 of the outer barrel.

The first opening 80.1 of the rear cover plate is located on one side of the second opening 80.2 of the rear cover plate.

[0034] The rear end of the connecting pipe 60 is wound around and positioned on the rear cover plate 80.

[0035] In this embodiment, the rear end of the connecting pipe 60 wound around is positioned by the rear cover plate 80, which can avoid the problem of displacement of the rear end of the connecting pipe 60 after assembly. That is, after the connecting pipe 60 is assembled, its front and rear ends are respectively positioned by the front cover plate 70 and the rear cover plate 80, so as to ensure that the connecting pipe 60 can be stably wound around the outer wall of the inner barrel 40, thereby improving the assembly stability of the position of the connecting pipe 60.

[0036] The front end of the outer barrel 50 is provided with a front opening 50.4 of the outer barrel. A bearing 90 is provided on the front opening 50.4 of the outer barrel, and a transmission shaft 10 is rotatably connected through the bearing 90.

The front positioning member 20 is positioned on the front opening 50.4 of the outer barrel and is cooperatively connected with the bearing 90. A positioning member opening 20.1 is provided on the front positioning member 20. The transmission shaft 10 is located in the second inner barrel cavity 40.3 and is rotatably arranged on the bearing 90. The front end of the transmission shaft 10 penetrates through the positioning member opening 20.1, and the rear end penetrates through the second opening 80.2 of the rear cover plate.

[0038] In this embodiment, after the front end of the transmission shaft 10 penetrates through the positioning member opening 20.1, it can be drivingly connected with the stirring blade sleeved on the outer wall of the outer barrel 50. After the rear end of the transmission shaft 10 penetrates through the second opening 80.2 of the rear cover plate, it can be drivingly connected with the driving motor arranged at the rear end of the outer barrel 50.
