Description

Technical Field

[0001] This utility model relates to the field of air curtain machine technology, specifically to an air curtain machine for central kitchens. Background Technology

[0002] Air curtain machines, also known as air curtain systems, are highly efficient air isolation devices widely used at entrances or passageways in shopping malls, hotels, factories, central kitchens, and other places. By generating a high-speed airflow curtain, they form an invisible air door, effectively blocking indoor and outdoor air convection and preventing the intrusion of external pollutants, insects, dust, and harmful gases. In central kitchens, as food processing areas, the invisible air door formed by the high-speed airflow curtain of air curtain machines not only effectively blocks external pollutants and insects from entering the central kitchen and reduces indoor and outdoor air exchange, thus ensuring the cleanliness and stable temperature and humidity of the food processing area, but also prevents cooking fumes from spreading to the living and dining areas outside the central kitchen, thereby providing consumers with a better dining experience.

[0003] However, existing air curtain machines have some significant shortcomings in installation and use. First, most air curtain machines, after being fixed to the wall by mounting brackets, typically have a fixed air outlet angle, making it impossible to quickly adjust the airflow direction according to changes in the work area or seasonal needs, thus affecting the effectiveness of use.

[0004] Secondly, central kitchen environments are typically characterized by high humidity and a lot of oil fumes, so air curtain machines require frequent cleaning and maintenance. However, existing air curtain machines are often directly fixed with bolts during installation, which leads to many inconveniences in subsequent cleaning and maintenance.

[0005] Therefore, it is necessary to design an air curtain machine for central kitchens that can be easily installed and disassembled and whose air outlet angle can be flexibly adjusted, in order to overcome the above-mentioned defects. Utility Model Content

[0006] The technical implementation scheme of this utility model is as follows: a central kitchen air curtain machine, comprising: two mounting plates, which are mounted on a wall, and the number of mounting plates is set to two; two adjusting seats, which are respectively mounted on both ends of the air curtain machine body; a connecting block, which is detachably mounted on the mounting plate; a mounting frame, one end of which is fixedly mounted on the connecting block, and the other end is connected to an arc-shaped plate; an arc-shaped locking block, which is rotatably mounted on the mounting frame and is adapted to the arc-shaped plate, the arc-shaped locking block and the arc-shaped plate enclosing and holding the adjusting seat; and a locking screw, which passes through the arc-shaped plate and the arc-shaped locking block from bottom to top, and is threadedly connected to a first locking nut provided on the arc-shaped locking block.

[0007] Optionally, the locking screw is threaded through the first locking nut and then wound with a spring, and the end of the locking screw is threadedly connected to a second locking nut.

[0008] Optionally, an adjustment block is installed on the adjustment seat.

[0009] Optionally, the adjustment block is set as a regular polygon.

[0010] Optionally, the adjustment block has a regular polygonal slot.

[0011] Optionally, the mounting plate is equipped with a hook on its front side, and the connecting block is provided with a hanging hole that matches the hook. The connecting block is detachably connected to the mounting plate through the cooperation of the hook and the hanging hole.

[0012] Optionally, a scale is provided on the arc-shaped plate, and a pointer is provided on the adjustment seat.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The angle of the air curtain machine body can be adjusted by rotating the adjustment seat through the adjustment block, so as to achieve the effect of flexibly and conveniently adjusting the angle of the air curtain machine body according to the use needs, thereby meeting diverse use needs and improving the adaptability of the air curtain machine body.

[0014] 2. The design of the hook and hanging hole allows the connecting block and the mounting plate to form a detachable connection, which greatly simplifies the installation and disassembly process of the air curtain machine and facilitates daily cleaning, maintenance or replacement.

[0015] 3. The arc-shaped locking block and the arc-shaped plate effectively enclose and fix the adjusting seat through the threaded engagement of the locking screw and the first locking nut. With the cooperation of the spring and the second locking nut, the stability of the connection between the locking screw and the first locking nut is enhanced, ensuring that the air curtain machine remains stable during long-term operation and reducing displacement or loosening caused by vibration.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: An air curtain machine for a central kitchen, such as Figures 1-6 As shown, the system includes a mounting plate 2, a connecting block 3, a mounting bracket 4, an arc-shaped locking block 5, a locking screw 6, a first locking nut 7, and an adjusting seat 10. The mounting plate 2 is installed on the wall 100, and two plates are provided. Two adjusting seats 10 are respectively installed at both ends of the air curtain machine body 1. The connecting block 3 is detachably mounted on the mounting plate 2. An "L"-shaped hook 21 is installed on the front of the mounting plate 2, and the hook 21 is integrally formed with the mounting plate 2. The connecting block 3 has a hanging hole 31 that matches the hook 21. The connecting block 3 is detachably connected to the mounting plate 2 through the cooperation of the hook 21 and the hanging hole 31, thereby enabling the connecting block 3 to be quickly suspended on or quickly removed from the mounting plate 2, thus achieving detachable mounting of the air curtain machine body 1. The mounting bracket 4 is installed to facilitate convenient maintenance and cleaning of the air curtain machine body 1. One end of the mounting bracket 4 is fixed to the connecting block 3 by bolts, and the other end is connected to the arc plate 41, with the arc opening of the arc plate 41 facing upwards. The arc locking block 5 is rotatably mounted on the mounting bracket 4 by hinge, and it is adapted to the arc plate 41 of the mounting bracket 4. The arc locking block 5 and the arc plate 41 surround and hug the adjusting seat 10. The locking screw 6 passes through the arc plate 41 and the arc locking block 5 from bottom to top, and is threadedly connected to the first locking nut 7 set on the arc locking block 5. Through the cooperation of the locking screw 6 and the first locking nut 7, the arc plate 41 and the arc locking block 5 tightly hug the adjusting seat 10, thereby realizing the effective connection between the adjusting seat 10 and the mounting bracket 4.

[0025] like Figure 5 As a result, after the locking screw 6 passes through the first locking nut 7, a spring 9 is wound around it. The end of the locking screw 6 is threadedly connected to a second locking nut 8. The spring 8 provides preload force, so that the locking screw 6 maintains elastic pressure when tightened, reducing loosening caused by vibration. The second locking nut 8 is an anti-loosening nut, which further effectively locks the locking screw 6, ensuring that the long-term connection between the locking screw 6 and the first locking nut 7 is stable and reliable.

[0026] like Figure 4 As shown, an adjustment block 11 is installed on the adjustment base 10. The adjustment block 11 is a regular polygon, preferably a regular hexagon, which makes it easy to match with a standard wrench and thus conveniently adjust the angle of the air curtain machine body 1.

[0027] like Figure 4 As shown, the adjusting block 11 has a regular polygonal groove, preferably a regular hexagonal groove, which facilitates its adaptation to the internal hex wrench, thereby achieving its adaptation and compatibility with a variety of tools.

[0028] like Figures 4-6 As shown, a scale 12 is provided on the arc plate 41 and a pointer 13 is provided on the adjustment seat 10. Through the cooperation of the scale 12 and the pointer 13, the air outlet angle of the air curtain machine body 1 can be accurately and intuitively adjusted.

[0029] During installation, firstly, the mounting plate 2 is pre-installed onto the wall 100 according to the pre-installation position of the air curtain machine body 1. Then, the mounting bracket 4 is rotated onto the hook 21 via the connecting block 3, thereby facilitating the convenient installation of the air curtain machine body 1. Next, the adjusting seat 10 is installed at both ends of the air curtain machine body 1. Then, the adjusting seat 10 is placed on the arc plate 41. The arc locking block 5 is then flipped over and surrounds the arc plate 41. The locking screw 6 is passed through the arc plate 41 and the arc locking block 5 from bottom to top and locked with the first locking nut 7. This effectively fixes the adjusting seat 10 onto the arc plate 41, thereby installing the air curtain machine body 1 onto the wall 100.

[0030] When it is necessary to change the airflow direction of the air curtain machine, first, loosen the locking screw 6, and then use a tool to drive the adjusting block 11 to rotate, thereby driving the adjusting seat 10 to rotate, thereby adjusting the angle of the air curtain machine body 1. The angle of the air curtain machine can be precisely adjusted by using the scale 12 and pointer 13. After the adjustment is completed, tighten the locking screw 6 and the first locking nut 7 again, thereby efficiently adjusting the airflow angle of the air curtain machine body 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
