Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration and fresh-keeping, and more precisely to a refrigeration box. Background Art

[0002] With society's increasing demands for the quality of fresh food and medicine, and the booming development of the food cold chain and fresh food e-commerce, the market demand for cold chain has significantly expanded. However, as the weak link in the cold chain, the last mile of the cold chain has always been a headache for fresh food distributors and sellers. Intercity cold chain logistics vehicle technology is basically mature, but after delivery to the target city logistics center, it is interrupted. Electric tricycles without any refrigeration effect are responsible for the end-to-end delivery task. The cold chain logistics has not formed a complete closed loop, and the cold chain quality cannot be guaranteed, resulting in an increase in cargo damage rate. Small new energy refrigerated trucks fill this gap. Therefore, small new energy refrigerated trucks came into being.

[0003] Refrigerated boxes are important components of cold chain vehicles to ensure the cold chain transportation of food and medical supplies. The refrigeration and heat preservation effects of refrigerated boxes directly affect the quality of the materials transported in the box. The refrigerated boxes in the prior art include a box body, on which a refrigerator is provided. When working, the refrigerator blows cold air into the box body to keep the materials in the box body warm. However, the refrigerated boxes in the prior art have the following defects: since there are many items stacked in the box body, they are generally stacked relatively high, which will block the air outlet of the refrigerator. In this way, the cold air blown out by the refrigerator will be blocked by the items and cannot be quickly diffused to other parts of the box body. The cold air distribution is prone to unevenness, resulting in lower temperatures near the air outlet and higher temperatures far away from the air outlet, which makes the overall cooling effect of the box body poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a refrigerated box, wherein when the refrigerated box is in use, the cold air inside is evenly distributed, thereby effectively improving the refrigeration effect of the box body.

[0005] The technical solution of the present utility model is to provide a refrigerator with the following structure, including a box body, a refrigerator installed on the box body, an air outlet of the refrigerator arranged in the box body, an air guide plate provided at the air outlet of the refrigerator, and a plurality of guide grooves provided on the inner wall of the box body; the cold air blown out from the air outlet of the refrigerator blows into the guide grooves, and the guide grooves can guide the cold air to various places in the box body.

With this structure, the first guide grooves extend along the length of the top plate, guiding the cold air from the front end of the housing to the rear end of the housing, thereby effectively distributing the cold air.

[0010] Further preferably, the inner wall of the bottom plate of the cabinet is provided with a plurality of mutually parallel second guide grooves, extending along the length of the bottom plate. The cold air at the rear of the cabinet can flow back through the second guide grooves to the return air outlet of the refrigerator, thereby forming a circulation.

[0011] Further preferably, a plurality of mutually parallel third guide grooves are provided on the inner wall of the front side panel of the cabinet. The third guide grooves extend along the height direction of the front side panel and can guide the cold air to the return air outlet of the refrigerator. With this structure, the cold air in the cabinet is more evenly distributed.

[0012] Further preferably, a plurality of mutually parallel fourth guide grooves are respectively provided on the left and right inner walls of the box, and the fourth guide grooves extend along the length direction of the inner wall. With this structure, the cold air in the box is more evenly distributed.

[0013] Preferably, the refrigerator is located on the upper side of the front end of the box, the air outlet is located at the rear end of the refrigerator housing, and the return air outlet is located at the lower side of the refrigerator housing.

[0014] Further preferably, the air guide plate is provided with an air guide groove, one end of the air guide plate is fixedly connected to the rear end surface of the refrigerator housing, the side wall of the air guide plate opposite the air outlet is an inclined wall, the side walls on both sides of the air guide plate are connected to the top of the housing, and an air duct is formed between the air guide plate and the inner wall of the housing. With this structure, the inclined wall guides the cold air, and the air guiding effect is better.

[0015] Preferably, the front end of the top plate of the box body is provided with a boss, and the refrigerator is mounted on the boss; the side walls on both sides of the air guide plate are provided with splicing grooves that match the boss, and the splicing grooves abut the boss. With this structure, the splicing effect between the air guide plate and the boss is better, and air leakage will not occur.

[0016] Further preferably, the sidewalls of both sides of the air deflector are provided with first flanges near the ends of the refrigerator, and the first flanges are fixedly connected to the rear end surface of the refrigerator housing. With this structure, the air deflector is fixedly connected to the refrigerator housing via the first flanges, resulting in a simple connection structure and easy assembly.

[0017] Further preferably, the side walls on both sides of the air deflector are provided with second flanges, and the second flanges are fixedly connected to the boss. With this structure, the air deflector is fixedly connected to the boss via the second flanges, and the connection structure is simple and easy to assemble. BRIEF DESCRIPTION OF THE DRAWINGS
