A front cover plate of the refrigeration air duct is designed, including a baffle mechanism, by setting a rotatable baffle at the air outlet. When the fan is working, the wind blows the baffle to send air and cools down; when the fan is not working, the baffle droops the air outlet to prevent heat from entering the freezing room.
It effectively avoids defrost heat entering the freezing room, reduces the load pack temperature rise in the freezing room, and improves food storage conditions.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator refrigeration, and particularly relates to a front cover plate of a freezing air duct. Background Technique
[0002] The freezing air duct is an important part of the refrigerator refrigeration system, including a front cover plate of the freezing air duct, a rear cover plate of the freezing air duct, air duct foam, a sensor, a fan, etc. The main function of the freezing air duct is to evenly blow the cold of the fin evaporator to the entire freezing compartment through the air outlet.
[0003] Currently in the refrigerator industry, the air outlets of the freezing air ducts are always in an open state, resulting in the heat of the heater naturally convecting to the freezing compartment during the defrosting period, causing a relatively high temperature rise in the load package temperature of the freezing compartment, which is not conducive to food storage during the actual use process of users. Content of the Utility Model
[0004] The purpose of the utility model is to provide a front cover plate of a freezing air duct to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A front cover plate of a freezing air duct includes a freezing air duct cover plate. One side of the surface of the freezing air duct cover plate is fixedly connected with an installation mechanism. The installation mechanism includes an installation plate, an air outlet part, connection columns, clamping blocks, and a wire harness fixing block. One side surface of the freezing air duct cover plate is fixedly connected with an installation plate. The top surface of the installation plate is fixedly provided with an air outlet part. Both sides of the surface of the installation plate are fixedly connected with a plurality of connection columns. Both sides of the bottom end of the installation plate are fixedly connected with clamping blocks. One side surface of the installation plate is fixedly provided with a wire harness fixing block.
[0007] One side of the air outlet part is fixedly connected with a baffle mechanism. The baffle mechanism includes an air outlet, a baffle, a rotating shaft, and an installation hole. A plurality of air outlets are fixedly opened on the top surface of the freezing air duct cover plate. Installation holes are fixedly opened on both sides of the air outlet. The inner wall of the installation hole is movably connected with a rotating shaft. A baffle is fixedly connected to the surface of the rotating shaft.
[0008] Preferably, the baffle is sleeved on the rotating shaft and is rotatably arranged in the installation hole through the rotating shaft. By sleeving the baffle on the surface of the rotating shaft, the baffle can rotate to block the wind at the air outlet to avoid dust accumulation when not in use.
[0009] Preferably, there are two installation holes, and the two installation holes are symmetrically opened on the laterally opposite sides of the air outlet. The symmetrical installation of the two in opposite directions enables the baffle to rotate in the installation holes.
[0010] Preferably, the length of the shaft is greater than the lateral width of the baffle; a through hole is provided in the upper portion of the baffle, one end of the shaft is fixed in one of the mounting holes, and the other end of the shaft passes through the through hole and is fixed in another mounting hole. By arranging a baffle at the air outlet of the freezing air duct cover, when the fan is working, the wind blows open the baffle to supply air to the freezing chamber for cooling, and the refrigeration is normal; when the fan is not working, the baffle droops due to gravity and blocks the air outlet.
[0011] Preferably, the baffle further includes: a chamfered portion, which is arranged on the side of the baffle close to the through hole and away from the windward side; a right-angled portion, which is arranged on the side of the baffle away from the through hole and on the same side as the chamfered portion. By providing a baffle with a chamfered portion, jamming during rotation can be avoided.
[0012] Preferably, a fan is fixedly connected to one side of the surface of the freezing air duct cover plate, and the fan can be provided to blow cold air into the refrigerator body through the air outlet.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The front cover of the freezing air duct is provided with a mounting mechanism for the freezing air duct cover. The freezing air duct cover can be mounted on the inner wall surface of the refrigerator through connecting columns and clamping blocks. The fan of the freezing air duct cover can be powered on through a reserved wiring harness fixing block, thereby achieving the purpose of portable disassembly and assembly and centralized wiring harness arrangement.
[0015] 2. The front cover of the freezing air duct is provided with a baffle mechanism on one side of the freezing air duct cover, which is rotatably arranged at the air outlet through a baffle. By arranging the baffle at the air outlet of the freezing air duct cover, when the fan is working, the wind blows open the baffle to supply air to the freezing chamber for cooling and normal refrigeration; when the fan is not working, the baffle droops due to gravity to block the air outlet, thereby preventing defrosting heat from entering the freezing chamber, thereby solving the technical problem in the prior art that the air outlet of the freezing air duct is always open, resulting in heat convection to the freezing chamber during defrosting, which is not conducive to food storage.
