A refrigeration device with odor removal function

Abstract

This utility model discloses a freezing device with odor removal function, relating to the field of food freezing technology. It includes an insulated outer wall, with a cover plate rotatably connected to one side of the top of the insulated outer wall. A circulation pipe is connected to the cover plate, and an exhaust motor is fixedly connected to the top of the circulation pipe. A set of exhaust fan blades is connected to the output end of the exhaust motor. This utility model, through the arrangement of the circulation pipe and exhaust fan blades, draws gas from inside the freezer into the circulation pipe, and then returns it to the freezer through an adsorption frame filled with adsorbent material, forming a circulating airflow. This allows the air in the freezer to fully pass through the adsorption frame, causing odor molecules in the air to be adsorbed by the adsorption material inside the adsorption frame, thereby removing odors from the freezer and preventing cross-contamination of flavors from the long-term storage of various foods. Furthermore, the exhaust motor is located outside the circulation pipe and the freezer, preventing the heat generated by the exhaust motor during operation from affecting the low-temperature environment inside the freezer.

Description

Technical Field

[0001] This utility model relates to the field of food freezing technology, specifically a freezing device with odor removal function. Background Technology

[0002] Freezing equipment refers to an auxiliary device that uses modern freezing technology to lower the temperature of food to a temperature below its freezing point in the shortest possible time. This causes most of the water content of the food to form tiny ice crystals as heat dissipates from the food's interior, thus maximizing the preservation of the food's original natural quality. However, when storing different types of food, odors can accumulate in the freezer and affect the flavor of other foods, thus requiring deodorization. Existing freezing equipment with deodorization functions (publication number: CN221724668U) has at least the following defects in use:

[0003] The above solution involves installing a fan, a first deodorizer and a second deodorizer inside the refrigeration unit. The first and second deodorizers release active oxygen and negative ions, which can quickly capture and decompose odor molecules in the refrigerator, thus eliminating odors. However, in actual use, the fan generates heat when running inside the unit, affecting normal refrigeration operations and increasing refrigeration energy consumption. Therefore, a refrigeration unit with odor removal function needs to be developed. Utility Model Content

[0004] The main purpose of this invention is to provide a refrigeration device with odor removal function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A refrigeration device with odor removal function includes an insulated outer wall. A cover plate is rotatably connected to one side of the top of the insulated outer wall. Two symmetrically distributed circulation vents are opened on the top side of the cover plate. A circulation pipe is fixedly connected between the inner walls of the two circulation vents.

The bottom side of the compression chamber is provided with multiple evenly distributed casters.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

Furthermore, the exhaust motor is located outside the circulation pipe and the freezer to prevent the heat generated by the exhaust motor from affecting the low-temperature environment inside the freezer.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A refrigeration device with odor removal function includes an insulated outer wall 101. A cover plate 201 is rotatably connected to one side of the top of the insulated outer wall 101. Two symmetrically distributed circulation air ports 206 are opened on the top side of the cover plate 201. A circulation pipe 202 is fixedly connected between the inner walls of the two circulation air ports 206. A suction motor 204 is fixedly connected to the top side of the circulation pipe 202. The output end of the suction motor 204 extends to the inner wall of the circulation pipe 202 and is fixedly connected to a set of suction fan blades 203. An adsorption frame 303 is arranged between the inner walls of the circulation pipe 202. Multiple evenly distributed vent holes 304 are opened on both sides of the adsorption frame 303. The inner walls of the adsorption frame 303 are filled with adsorbent material. In this embodiment, the adsorbent material is generally activated carbon. The operation of the suction motor 204 generates a circulating airflow, which adsorbs odor molecules in the air inside the insulated outer wall 101 through the activated carbon inside the adsorption frame 303, thereby achieving the purpose of odor removal.

[0024] An adsorption port is provided on one side of the adsorption frame 303, extending through the adsorption port to the outside of the circulation pipe 202. A handle 302 is fixedly connected to the end of the adsorption frame 303 extending to the outside of the circulation pipe 202. An adsorption flap 301 is rotatably connected to the top side of the end of the adsorption frame 303 extending to the outside of the circulation pipe 202. The outer edge of the top side of the adsorption flap 301 is slidably connected to the inner wall of the top side of the circulation pipe 202. A sealing block 305 is provided at the end of the adsorption flap 301 facing the inside of the circulation pipe 202, and the sealing block 305 is engaged with the top of the corresponding side of the adsorption frame 303. A heat-insulating flap 205 is rotatably connected to the top of the side of the cover plate 201 facing away from the heat-insulating outer wall 101 and the side where the cover plate 201 is connected. The inner wall of the heat-insulating flap 205 covers the circulation pipe 202. In this embodiment, after opening the heat insulation cover 205, the adsorption frame 303 can be pulled out through the handle 302 to replace the activated carbon in the adsorption frame 303 and maintain the odor adsorption effect.

[0025] A compression chamber 106 is fixedly connected to the bottom side of the insulated outer wall 101. A compressor is installed inside the compression chamber 106. An air inlet is located on one side of the compression chamber 106, and a ring of air inlet pipes 105 is arranged between the inner walls of the air inlet. The air inlet pipes 105 are connected to the compressor input end, and an air inlet grille 104 is arranged between the inner walls of the air inlet pipes 105. Multiple evenly distributed heat transfer pipes 102 are embedded inside the insulated outer wall 101. Each heat transfer pipe 102 connects to the inside of the compression chamber 106 and is connected to the compressor output end. Multiple evenly distributed casters 103 are provided on the bottom side of the compression chamber 106. In this embodiment, the heat transfer pipes 102 have a D-shaped cross-section, and their straight surfaces resemble the inside of the insulated outer wall 101, improving the heat transfer effect. The compressor then operates to perform the refrigeration process.

[0026] It should be noted that this utility model, as a refrigeration device with odor removal function, draws gas from inside the freezer into the circulation pipe 202 through the circulation pipe 202 and the exhaust fan blade 203. The gas then returns to the freezer through the adsorption frame 303 filled with adsorbent material, forming a circulating airflow. This allows the air in the freezer to pass fully through the adsorption frame 303, causing odor molecules in the air to be adsorbed by the adsorption filler inside the adsorption frame 303, thereby removing odors from the freezer and preventing cross-contamination of flavors from the long-term storage of various foods. Furthermore, the exhaust motor 204 is located outside the circulation pipe 202 and the freezer to prevent the heat generated by the exhaust motor 204 from affecting the low-temperature environment inside the freezer.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
