Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a small cold storage energy-saving refrigeration equipment. Background Art

[0002] Cold storage is a type of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment with different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments, etc. There are many types of refrigeration equipment in cold storage. For small cold storage, air coolers are one of the most commonly used refrigeration equipment. However, the air coolers currently used in small cold storage have the following disadvantages:

[0003] Since the space of a small cold storage is small, frequent door opening will cause hot air from outside to enter the cold storage, causing the temperature inside the cold storage to rise. The air outlet of the existing air cooler is fixed, so when the air cooler is working, it can only blow cold air in one direction. It is difficult to make the temperature inside the small cold storage reach uniformity in a short time, which increases the working time of the air cooler and thus increases energy consumption. Secondly, the water receiving tray at the bottom of the air cooler is easy to freeze after receiving the defrosted water, which makes it difficult to drain the water in the water receiving tray and often requires manual cleaning. Therefore, the utility model proposes an energy-saving refrigeration device for a small cold storage. Utility Model Content

[0022] like Figure 1-Figure 4 As shown, it relates to an energy-saving refrigeration equipment for a small cold storage, including an air cooler 1, a fan 2 is fixedly connected to the air outlet of the air cooler 1, an annular plate 3 is fixedly connected to the side of the fan 2 away from the air cooler 1, an arc-shaped air duct 4 is rotatably sleeved on the surface of the annular plate 3, a bottom box 5 is fixed on the outer wall of the air cooler 1 and located below the fan 2, a rotating drive component for driving the arc-shaped air duct 4 to rotate is arranged inside the bottom box 5, a water collecting pan 8 is fixedly connected to the bottom end of the air cooler 1, a coil 10 is fixed to the inner bottom wall of the water collecting pan 8, and a heat circulation component connected to the coil 10 is installed inside the bottom box 5.

[0023] like Figure 1 As shown, a mounting frame 16 is fixed on the upper surface of the air cooler 1 .

[0024] The length of the mounting frame 16 is greater than the width of the air cooler 1, and mounting holes are provided at both ends of the mounting frame 16, through which the air cooler 1 can be fixed to the top wall of the cold storage.

[0025] like Figure 1-Figure 3 As shown, an annular groove 31 is formed on the outer wall of the annular plate 3 , and a ridge 41 is fixed on the inner wall of the arc-shaped air duct 4 near the annular groove 31 . The ridge 41 is located inside the annular groove 31 and is slidably connected to the annular groove 31 .

[0026] The convex ridge 41 is stuck in the annular groove 31 , so that the arc-shaped air guide duct 4 will not be separated from the annular plate 3 when rotating.

[0027] like Figure 1-Figure 4As shown, the rotary drive assembly includes a reduction motor 6 fixed to the inner wall of the bottom box 5, the output shaft of the reduction motor 6 passes through the side wall of the bottom box 5 and is fixedly connected to a gear 7, a gear ring 42 is fixed to the outer wall of the arc-shaped air duct 4 and close to one side of the bottom box 5, and the gear 7 is meshed with the gear ring 42.

[0028] The gear 7 is driven to rotate by the reduction motor 6, and the gear 7 drives the gear ring 42 to rotate, thereby realizing the rotation of the arc-shaped air guide duct 4 on the surface of the annular plate 3, and constantly changing the wind direction of the air blown out by the fan 2.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, the thermal circulation component includes a water tank 11 fixed to the bottom wall of the bottom box 5, a pump body 12 and a hose 13 wrapped around the outer shell surface of the reduction motor 6, one end of the hose 13 is fixedly connected to the water outlet of the pump body 12, the other end of the hose 13 is connected to one end of the coil 10, the other end of the coil 10 is fixedly connected to a return pipe 15, the other end of the return pipe 15 is connected to the top wall of the water tank 11, the water inlet of the pump body 12 is fixedly connected to a pumping pipe 14, and the pumping pipe 14 is connected to the side wall of the water tank 11.

[0030] A drain pipe 9 is fixedly connected to the bottom wall of the water receiving tray 8 .

[0031] When the reduction motor 6 is working, it generates heat, which heats the water in the hose 13. After the hot water enters the coil 10, it can prevent the water in the water receiving tray 8 from freezing, thereby ensuring that the defrosted water in the water receiving tray 8 can be smoothly discharged from the drain pipe 9.

[0032] Working principle: When the air cooler 1 is working, the reduction motor 6 starts, and the reduction motor 6 drives the arc-shaped air duct 4 to rotate on the surface of the annular plate 3 through the gear 7, so that the air outlet of the arc-shaped air duct 4 constantly changes the wind direction, so the cold air blown out by the fan 2 will be blown along the arc-shaped air duct 4 to all directions of the cold storage, so that the temperature of all parts of the cold storage is rapidly reduced and reaches uniformity. When the internal defrosting mechanism of the air cooler 1 is working, the melted water will fall into the water receiving tray 8, and the pump body 12 will start at this time. The pump body 12 will pump the water in the water tank 11 and pump it into the hose 13. The hose 13 wrapped around the surface of the reduction motor 6 will be heated by the heat generated by the reduction motor 6. Then the hot water enters the coil 10 to prevent the water in the water receiving tray 8 from freezing. Then the water in the coil 10 returns to the water tank 11 along the return pipe 15 to achieve circulation.
