Description

Technical Field

[0001] This invention belongs to the field of food preservation equipment technology, specifically relating to a convenient food preservation and rapid cooling device. Background Technology

[0002] In the food processing, catering, and home sectors, rapidly cooling cooked hot food to a safe refrigeration temperature is crucial for ensuring food safety and locking in flavor and nutrients. Traditional methods such as natural cooling or home refrigeration are slow, leaving food in a "dangerous temperature zone" where bacteria can easily grow for extended periods. Furthermore, these methods suffer from uneven cooling, high energy consumption, and can negatively impact other foods in the refrigerator.

[0003] In the existing technology, there are rapid cooling devices that combine fans and refrigeration systems. However, these devices usually have defects in the internal airflow organization, such as uneven airflow distribution and the existence of cooling dead zones, resulting in poor temperature field uniformity inside the chamber and inconsistent cooling effects on food in different locations.

[0004] In addition, common cooling coil structures suffer from problems such as insufficient heat exchange efficiency, high system resistance, or uneven coolant distribution. At the same time, the accumulation and poor drainage of condensate may also affect the hygiene and service life of the equipment. Therefore, this invention provides a convenient food preservation and rapid cooling device. Utility Model Content

[0005] The purpose of this invention is to provide a convenient food preservation and rapid cooling device that can solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is as follows: a convenient food preservation and rapid cooling device, including a box body, an upper mounting base fixedly connected to the top of the box body, at least one set of fan mechanisms built into the upper mounting base, and an independent inner box body fixedly connected inside the box body. The upper and lower ends of the inner box body are both outwardly flared, while its horizontal sides are inwardly constricted, forming an air duct structure for guiding airflow downward and evenly. The inner casing has an internal frame and a bottom mesh frame arranged from top to bottom. The cavity between the main casing and the inner casing is filled with a filling layer and is fixedly connected to a cooling system. The air outlet of the fan mechanism is sealed to the air inlet at the top of the inner casing through an inner guide shroud. A guide pipe is embedded at the bottom between the main casing and the inner casing.

[0007] The utility model is further configured such that: a sealing groove is provided on the front of the box, and a sealing cover is provided accordingly; a labyrinth press-fit sealing strip is provided on the inner edge of the sealing cover to cooperate with the sealing groove; and magnetic buckles are provided at the inner corner of the sealing cover and the front corner of the box.

[0008] This utility model is further configured such that: the inner box is made of food-grade stainless steel with a matte finish on the inner surface; the outer shell is made of galvanized steel sheet; and the inner wall panels are provided with vertical and horizontal reinforcing ribs.

[0009] This utility model is further configured such that: the fan mechanism is a backward-inclined centrifugal fan, and the inner guide shroud is a trapezoidal shroud structure made of food-grade silicone rubber with a corrugated layer.

[0010] This utility model is further configured as follows: the cooling system includes two sets of cooling main pipes vertically arranged on both sides of the box body and the inner box cavity, and multiple sets of vertically equidistant arc-shaped connecting pipes. The connecting pipes and cooling main pipes are arranged in a "U" shape longitudinally. The two sets of cooling main pipes are interconnected at their bottoms through a horizontal connecting pipe. The upper ends of the multiple sets of connecting pipes are all connected to one of the cooling main pipes, and the lower ends are all connected to the other cooling main pipe. The multiple sets of connecting pipes are independent of each other and are connected in parallel.

[0011] This utility model is further configured such that: the connecting pipe has raised aluminum fins on the inner surface facing the inner box; the cooling main pipe and the connecting pipe are both made of copper pipe and are connected to each other by silver brazing.

[0012] This utility model is further configured such that both the inner frame and the bottom mesh frame are made of food-grade stainless steel and have a high openwork mesh frame structure. The inner frame is fixedly connected to the inner wall of the inner box through the insertion seats at both ends.

[0013] This utility model is further configured such that the filling layer is a high-pressure integrally foamed polyurethane foam insulation layer.

[0014] This utility model is further configured such that an S-shaped water trap is provided at the end of the guide pipe.

[0015] The technical effects achieved by this utility model are as follows: This utility model presents a convenient food preservation and rapid cooling device. It provides uniform cooling without any dead zones. Based on the outward tilting of the inner chamber and the inward tilting of the sides, together with the inner guide shroud, it forms a Venturi effect air duct. Combined with the "top-supply, bottom-return" vertical laminar flow design, the forced cold air can evenly and comprehensively cover all layers of food, thereby effectively eliminating cooling dead zones and ensuring a high degree of uniformity in the temperature field inside the chamber.

[0016] This invention relates to a convenient food preservation and rapid cooling device with extremely high heat exchange efficiency. The back-mounted cooling system is located directly on the return air path, which can efficiently cool the air to be circulated. Secondly, the aluminum fins on the connecting pipes greatly increase the heat exchange area. Finally, the parallel pipe design reduces flow resistance, thereby effectively ensuring that the coolant flows evenly in each branch, thus maximizing the heat exchange efficiency.

[0017] This utility model discloses a convenient food preservation and rapid cooling device. The outward tilting structure of the bottom of the inner chamber effectively guides the condensate to collect, and the S-shaped water trap at the end of the guide pipe prevents external air from flowing back in, ensuring the airtightness of the chamber. At the same time, the combination of the labyrinth press-fit sealing strip and the magnetic buckle provides a good sealing effect, effectively isolating internal and external heat exchange, and saving energy and reducing consumption.

One end of the guide pipe 9 extends to the outside of the housing 1.

[0022] like Figure 1-2As shown, the box 1 is rectangular in shape, with a sealing cover on the front. Magnetic buckles are provided at the inner corners of the sealing cover and the front corners of the box 1. A labyrinth-type sealing strip is provided on the inner edge of the sealing cover corresponding to the sealing groove 5. The sealing strip is a hollow foamed silicone strip. The upper and lower ends of the inner box 4 are inclined outwards, while the two sides of the inner box 4 are inclined inwards. The inclined surfaces on both sides of the upper end of the inner box 4 are located below the fan mechanism 3. The sealing groove 5 is opened on the front of the box 1 along the outline of the inner box 4. The fan mechanism 3 is a backward-inclined centrifugal fan. The outer shell of the box 1 is made of galvanized steel plate with a food-contact grade epoxy resin powder coating, while the inner box 4 is made of food-grade stainless steel with a matte finish. Vertical and horizontal reinforcing ribs are provided inside the box 1.

[0023] like Figure 2-4 As shown, the inner guide shroud 8 is a trapezoidal shroud with a corrugated layer. Its upper and lower ends are sealed to the corresponding fan mechanism 3 and inner housing 4. The upper end of the inner housing 4 has a sealed opening corresponding to the inner guide shroud 8. The inner guide shroud 8 is made of food-grade silicone rubber. An S-shaped water trap is provided at the end of the guide pipe 9. Two sets of cooling main pipes 10 are vertically arranged on both sides of the cavity between the housing 1 and the inner housing 4, and are connected to the connecting pipe 11.
