Description

Technical Field

[0001] This utility model belongs to the technical field of draft beer machines and relates to a suspension stirring device for a draft beer machine. Background Technology

[0002] A draft beer dispenser is a refrigeration device specifically designed for dispensing keg beer, belonging to the category of beer and beverage equipment. Its core function is to rapidly cool the beer flowing through the beer tube using a built-in compressor refrigeration system, while simultaneously using carbon dioxide pressure to stably deliver the beer, ensuring a refreshing taste and fine foam.

[0003] Existing draft beer machines, such as the water-cooled draft beer machine disclosed in Chinese patent literature [Patent No.: 201621113701.7; Application Publication No.: CN206113504U], include a housing with a refrigeration circuit including a compressor, a condenser, and refrigeration pipes inside. A water tank is located inside the housing, and the refrigeration pipes are coiled within the water tank. The housing also has a refrigeration chamber and a beer dispensing pipe. A beer dispensing tap is connected to the outside of the housing. The beer dispensing pipe is coiled within the water tank and connected to the beer dispensing tap. A refrigeration chamber is located within the refrigeration chamber, and a cold water pipe is coiled within it. The inlet and outlet of the cold water pipe are both connected to the water tank. An air inlet and an air outlet are provided on the refrigeration chamber, and a fan is located inside the refrigeration chamber.

[0004] This type of draft beer dispenser has a stirring motor mounted above the water tank. The end of the motor shaft extends downwards into the water tank, and stirring blades are fixed to the end of the motor shaft. The stirring motor drives the stirring blades to rotate, thus agitating the cooling water in the tank, making the cooling water more evenly mixed, and achieving a better cooling effect. However, because the stirring motor is located above the water tank, the motor shaft needs to be very long to deliver the stirring blades to the appropriate position. This requires a large stirring motor, resulting in a large stirring motor and consequently a large draft beer dispenser. Furthermore, the stirring motor, being located above the water tank, is susceptible to moisture contamination, making it prone to damage and reducing its service life. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a suspension stirring device for a draft beer machine. The technical problem solved is how to miniaturize the draft beer machine and improve the service life of the motor.

[0006] The objective of this utility model can be achieved through the following technical solution: a suspension stirring device for a draft beer machine, the draft beer machine including a water tank, the suspension stirring device including a motor, characterized in that, a mounting cavity is formed by an upward protrusion at the center of the bottom wall of the water tank, the mounting cavity is not connected to the inner cavity of the water tank, the motor is positioned in the mounting cavity, a driving wheel is fixedly connected to the output shaft of the motor, a first magnet is fixedly connected to the driving wheel, a positioning shaft is provided at the center of the bottom wall of the water tank, a driven wheel is rotatably sleeved on the positioning shaft, the driven wheel is located in the inner cavity of the water tank, a second magnet is fixedly connected to the driven wheel, the driving wheel and the driven wheel are arranged opposite to each other, the first magnet and the second magnet are attracted by opposite poles, and the motor drives the driving wheel to rotate, which in turn drives the driven wheel to rotate.

[0007] During operation, due to the opposing arrangement of the driving and driven wheels, the first and second magnets attract each other, meaning the driving wheel pulls the driven wheel. The motor starts, driving the driving wheel to rotate, which in turn drives the driven wheel. This suspension agitation device only requires the driven wheel to be inside the water tank and in contact with the cooling water; the motor and driving wheel remain separate. The rotating driven wheel stirs the cooling water, thus improving the cooling effect of the beer machine. A mounting cavity is formed by an upward protrusion at the center of the water tank's bottom wall. The motor is fixedly connected to this cavity, meaning it is embedded within the water tank and does not occupy external space, allowing for miniaturization of the beer machine. Since the mounting cavity is not connected to the inner cavity of the water tank, the principle of magnet attraction ensures that the rotation of the driving wheel drives the rotation of the driven wheel. This prevents the cooling water inside the water tank from contaminating the motor, reducing its risk of damage and extending its lifespan, thereby extending the lifespan of the beer machine.

[0008] In the aforementioned suspension and stirring device for a draft beer machine, the driving wheel is positioned near the bottom surface of the water tank wall, with a gap between the driving wheel and the bottom surface of the water tank wall. The driven wheel is positioned near the top surface of the water tank wall, with a gap between the driven wheel and the top surface of the water tank wall. This structure brings the driving and driven wheels closer together, while preventing friction between the driving and driven wheels and the water tank. This allows the driving wheel to better drive the driven wheel to rotate, and the driven wheel to better agitate the cooling water, thereby improving the cooling effect of the draft beer machine.

[0009] In the aforementioned suspension and stirring device for a draft beer machine, the driving wheel has several equally spaced first mounting slots, with the openings of the first mounting slots facing downwards. A first magnet is fixedly connected to each of the first mounting slots. The driven wheel has several equally spaced second mounting slots, with the openings of the second mounting slots facing upwards. A second magnet is fixedly connected to each of the second mounting slots. The first magnet and the second magnet are arranged in a one-to-one correspondence. This structure ensures that the attraction between the opposite poles of the first and second magnets is moderate, allowing the driven wheel to better agitate the cooling water, thereby improving the cooling effect of the draft beer machine.

[0010] In the aforementioned suspension stirring device for a draft beer machine, a plurality of stirring blades are fixedly connected at equal intervals on the driven wheel, and the stirring blades are spaced apart from the second magnet. The arrangement of the stirring blades improves the agitation effect of the cooling water, allowing the driven wheel to better agitate the cooling water, thereby improving the cooling effect of the draft beer machine.

[0011] In the aforementioned suspension stirring device for a draft beer machine, a bearing is provided between the driven wheel and the positioning shaft. The bearing makes the rotation of the driven wheel smoother, allowing it to better agitate the cooling water, thereby improving the cooling effect of the draft beer machine.

[0012] In the aforementioned suspension stirring device for a draft beer machine, the wall of the mounting cavity has an annular stepped surface. A mounting plate is fixedly connected to the motor, with both ends of the mounting plate abutting against the stepped surface. Fasteners are inserted into the mounting plate and the bottom wall of the water tank, suspending the motor and fixing it within the mounting cavity. This structure facilitates motor installation.

[0013] In the aforementioned suspension stirring device for a draft beer machine, a sealing plate is fixedly connected to the bottom of the water tank, preventing the mounting cavity from communicating with the outside. This structure avoids external interference with the rotation of the drive wheel, making the motor less prone to damage and extending its service life.

[0014] In the aforementioned suspension and stirring device for a draft beer machine, the water tank is equipped with cooling pipes arranged in a ring, and the driven wheel is located at the bottom of the space enclosed by the cooling pipes. This structure, with its rationally positioned driven wheel, allows for better agitation of the cooling water, thereby improving the cooling effect of the draft beer machine.

[0015] Compared with the prior art, the suspension stirring device for a draft beer machine provided by this utility model has the following advantages:

[0016] 1. The bottom wall of the draft beer machine has an upward protrusion at the center to form a mounting cavity. The motor is fixed in the mounting cavity, that is, the motor is embedded in the water tank and does not occupy external space, thus enabling the draft beer machine to be miniaturized.

[0017] 2. The motor of this draft beer machine is fixed in the mounting cavity, which is not connected to the inner cavity of the water tank. Utilizing the principle of opposite poles attracting each other, the rotation of the drive wheel can drive the rotation of the driven wheel. In other words, the cooling water in the inner cavity of the water tank will not contaminate the motor, making the motor less prone to damage and extending its service life, thereby extending the service life of the draft beer machine.
