refrigerator

Abstract

The present invention provides a refrigerator, comprising: a box body defining a first cooling chamber, a second cooling chamber, a first storage compartment, a second storage compartment and a third storage compartment; the first The storage compartment and the second storage compartment are arranged side by side above the first cooling chamber; the second cooling chamber is arranged on the upper side of the third storage compartment; the first evaporator is arranged in the first cooling chamber; The second evaporator is arranged in the second cooling chamber; the first storage compartment is formed with at least one first air return port communicated with the first cooling chamber on its left side wall, so that the return air flow of the first storage compartment Enter the first cooling chamber through the first air return port for cooling; the second storage compartment is formed with at least one second air return port communicated with the first cooling chamber on its right side wall, so that the second storage compartment The return air flow enters the first cooling chamber through the second air return port for cooling; the lower surface of the second cooling chamber is provided with a third return air port communicating with the third storage compartment.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing devices, in particular to a refrigerator. Background technique [0002] The refrigerating air duct of traditional side-by-side refrigerators is usually placed on the rear side wall. Since the air duct composed of the first evaporator itself, the air supply fan, and the front and rear cover plates of the air duct is relatively thick, it occupies the space at the rear of the compartment, resulting in The usable volume is greatly reduced. At the same time, the cold air is sent to the storage compartment through the air supply fan. Due to the large space of the freezer compartment, the air volume transmission path is long and the cooling capacity loss is large. The farther away from the air outlet, the smaller the air volume. At the same time, in order to allow the defrosting water to flow out smoothly, the water receiving tray is usually designed as a funnel, and the existing refr...

AI Technical Summary

Problems solved by technology

At the same time, in order to make the defrosting water flow out smoothly, the water receiving tray is usually designed as a funnel, and the existing refrigerators do not use this part of the space, losing the effective volume

Moreover, in an air-cooled refrigerator, when the air is returned, especially when the refrigerator is returned, the moisture carried by the corresponding evaporator will condense on the surface, resulting in a continuous decrease in the humidity of the compartment and drying of the food; at the same time, in practical applications, especially for For the refrigerator room, the cold air inside the refrigerator sinks, and the traditional way of returning air makes insufficient use of the cooling capacity. At the same time, the hot air moves upwards, resulting in the highest temperature in the upper space, which is not good for food preservation in this area, and the utilization rate of the upper space is insufficient. , resulting in a waste of space

In addition, the evaporator in the refrigerating room mostly adopts a multi-row parallel structure, which is installed at the rear of the refrigerating room, and the fan is placed on the upper end of the refrigerating evaporator. This design mode has certain shortcomings, such as the thickness of the multi-row refrigerating evaporator is large, The depth of the compartment is reduced, and the usable space is reduced. The fan is installed at the upper end of the refrigeration evaporator. After the cooled air passes through the fan, it needs to pass through a long air duct to enter the compartment to exert the cooling effect. The loss in the air duct Most of the cold energy cannot be used by the compartment, which reduces the cooling capacity of the refrigerated evaporator

It can also lead to uneven temperature distribution in the refrigerator
