Description
Technical field
The present invention relates to refrigerating plant, relate in particular to a kind of refrigerating plant door sealing structure and refrigerating plant.
Background technology
Global energy is in short supply day by day serious, energy-conservation significant to national economy sustainable development and environmental protection.China has become the manufacture base of world's household electrical appliances maximum and maximum consumption market, along with strengthening gradually and the implementation of national step price policy of consumer's energy-conserving and environment-protective consciousness, has energy-conservationly become the large problem that China household electrical appliances industry faces.
At present mainly by adopt frequency-variable efficient press, condenser-reboiler optimal design, set up throttling arrangement, improve heat insulation layer structure, adopt efficient door seal technology to reduce the energy consumption of refrigerating plant, reach energy-conservation object.
The leakage thermic load of refrigerating plant directly affects the size of energy consumption, the leakage thermic load of refrigerating plant is mainly casing leaking heat, the leaking heat that opens the door, storing leaking heat and other (illumination, fan, anti-condensation pipe) leaking heat, and wherein casing leaking heat comprises again by the leaking heat of casing and door body heat-insulation layer, by the leaking heat of box structure and by the leaking heat of door seal.It is generally acknowledged, the leaking heat of common simple gate envelope accounts for 10% left and right of refrigerating plant total heat duties, reaches energy-conservation object for reducing leaking heat, need make particular design to door seal.Adopt efficient door seal technology can effectively reduce the leaking heat of refrigerating plant; strengthen the heat insulation effect of refrigerating plant; thereby the time that reduces on the one hand compressor operating is reduced energy consumption, reduces on the other hand the startup-shutdown number of times of refrigerating plant, reduces the unnecessary energy consumption causing in startup-shutdown process.Door sealing structure can make door lining and casing liner combine closely, and reduces leaking heat, and on the other hand, gasket itself also can hinder the transmission of heat, reduces leaking heat.
Current efficient door seal refers to double door seal structure, generally on energy-saving refrigerating device, has configuration, mainly comprises twice door seal, i.e. outer door sealer and interior door seal ensures the low leakage of cold with Double door seal.Outer door sealer is the gasket that is configured in doorframe position inside refrigerator door body, this gasket contains magnetic stripe, for magnetic force door seal, can be pull-in on the metal hemming edge of casing, interior door seal is arranged on the inner side of magnetic force door seal, in it, not containing magnetic stripe, do not realize sealing effectiveness with magnetic attraction, interior door seal and the direct press seal of box liner of door body while being mainly closed by outer door sealer.Interior door seal has reduced the transmission temperature difference of main door seal both sides, further intercepts the leakage of cold.
Though above-described double door seal structure can make leaking heat effectively reduce, it is still 5% left and right that door seal is leaked thermal ratio.
Summary of the invention
The object of this invention is to provide a kind of good sealing effect, the refrigerating plant door sealing structure that can make the leaking heat of refrigerating plant effectively reduce.
Another object of the present invention is to provide a kind of good sealing effect, the refrigerating plant that can make the leaking heat of refrigerating plant effectively reduce.
Refrigerating plant door sealing structure of the present invention, comprises the first door seal and the second door seal that are arranged on refrigerator door body inner side, and described the second door seal is arranged on the first door seal inner side;
On described door body, offer the groove between the first door seal and the second door seal, the position that the casing of described refrigerating plant is corresponding with described groove is provided with the projection with described groove fit, is provided with the 3rd door seal at the matching part of described groove and projection;
Or the position that described door body is positioned between the first door seal and the second door seal is provided with projection, on the casing of described refrigerating plant, the position corresponding with described projection is provided with the groove coordinating with described projection, is provided with the 3rd door seal at the matching part of described groove and projection.
