Description
Technical field
The present invention relates to a kind of refrigerator, wherein, reduced the heat transfer from the machine chamber to the refrigerator.
Background technology
The cold-producing medium cycle period of carrying out in refrigerator, the heat that receives from refrigerating chamber and refrigerating chamber is discharged into external environment condition by means of condenser.In conventional refrigerator, utilize the static type condenser of thermal natural convection principle work for preferred, and in frost-free refrigerator, it is preferred utilizing and forcing the coil-type condenser of thermal convection principle operation.In frost-free refrigerator, compressor and condenser are " heat " parts of cold-producing medium circulation and operate that machine chamber is known as the hatch base zone and it is usually located at the place, bottom of refrigerator main body in machine chamber.By means of the fan in machine chamber, provide heat from the condenser to the external environment condition discharging and the cooling of compressor is provided.The temperature of machine chamber because compressor and condenser have raise, then adjacent with machine chamber refrigerating chamber and refrigerating chamber also are subjected to the influence of this high temperature and need cooling, and have therefore increased energy consumption.
In Japanese patent application No. JP2006138609, explained a kind of refrigerator, wherein, be provided at the compressor operated in the machine chamber and the cooling of condenser by means of being positioned over axial fan between compressor and the condenser.
Summary of the invention
The objective of the invention is to realize a kind of refrigerator, wherein by making wherein compressor and condenser carry out the machine chamber thermal insulation of work, reduce the heat transfer of the part of near machine chamber refrigerating chamber and refrigerating chamber.
The refrigerator of realizing in order to reach purpose of the present invention is set forth in first claim and the requirement of its respective right, it comprises: machine chamber, it is arranged in the place, back bottom of its refrigerator main body and compressor and condenser operates in machine chamber, and the cooling of compressor and condenser is provided by means of axial fan.The separator plate that extends on condenser and the compressor from axial fan is arranged in machine chamber, and has the gap between separator plate and machine locular wall.Because separator is positioned at the summary below of the tip of fan leaf, the air that blows from the blade tip of fan enters in the gap between separator and machine locular wall, and by in the gap, providing air to flow to provide the thermal insulation efficiently in this zone.Thereby, reduced significantly towards the heat transfer of machine locular wall from compressor and condenser (it is " heat " parts of machine chamber), and the temperature of machine locular wall remains on the almost level of environment temperature.
In an embodiment of the present invention, thereby selected the diameter of fan to make the height of blade tip surpass the height of compressor and condenser, in other words, used with known embodiment and compared the fan with larger diameter.Thereby, by will be for example the smooth separator plate of rectangle be positioned on compressor and the condenser, the air that blows from the blade tip of fan directly is delivered to the gap.
In another embodiment of the present invention, separator is produced by plastics, and by means of the lower thermal conductivity feature of plastic material, has reduced the heat transfer towards the machine locular wall.
In another embodiment of the present invention, this refrigerator comprises: horizontal top wall, and extend vertically to the inside its back bottom from its main body, and its trip edge has warp architecture; Vertical inner wall; And separator is by bending to be positioned in machine chamber parallel with wall.
In another embodiment of the present invention, this refrigerator comprises extension, curved or inclination form, and it extends towards the center of fan from separator by bending; And its air that will blow from the tip of fan leaf is directed to the gap.The inclination angle of having determined extension is that the air that is suitable in the air stream of going out of fan flows and horizontal fans axis angulation.
In another embodiment of the present invention, at the stopping period of compressor and condenser, fan is with low-speed handing.
In refrigerator of the present invention, reduced from condenser and compressor around machine chamber wall and therefore towards the heat transfer of refrigerating chamber and refrigerating chamber, and provide the energy saving.
