Abstract
The utility model relates to a fresh-keeping energy-saving refrigerator controlling temperature precisely, which comprises a refrigerator body with an insulating layer, a door body, a refrigerating system and a control system. The refrigerating system comprises a compressor, a capillarity tube, a condenser, a refrigerating evaporator and a freezing evaporator. The refrigerating evaporator utilizes a double-channel counter flow S-shaped aluminum coil, the freezing evaporator utilizes a p-shaped threaded pipe type evaporator with uneven arranged pipelines, a temperature sensor utilizes a temperature sensing head cover plate with a porous structure, and orifices are uniformly distributed on lateral walls of a shelf approaching a container of a refrigerating chamber. The fresh-keeping energy-saving refrigerator is simple in structure and easy for application, can improve temperature field distribution and refrigeration capacity distribution inside each chamber, reduces temperature fluctuation, realizes precise temperature control, is favorable for fresh-keeping and storage of food, can simultaneously reduce power consumption of the refrigerator, and enables energy consumption of products to be superior than the national primary standard.
Description
Technical field
The utility model relates to household appliance technical field, especially relates to a kind of fresh-keeping energy-saving refrigerator of accurate temperature controlling.
Background technology
The fresh-keeping storage of food has outside the lower temperature environment except requiring the space of the few bacterium of a cleaning, and the stability of temperature and uniformity are also most important.Because the fluctuation of temperature and the temperature difference can make moisture in the food, vitamins and other nutritious components reduce greatly, and increase the generation of nitrite, harmful bacteria etc., edible back insalubrity.
Accurate temperature controlling and fresh-keeping energy-conservation be the technological difficulties of refrigerator always.Influence each other owing to pin down mutually between each factor, usually can attend to one thing and lose sight of another.For example, more energy-conservation for refrigerator, need usually to strengthen evaporator area, but this measure meeting causes the temperature fluctuation when the compressor start-stop of each chamber of refrigerator bigger, and can aggravate each indoor levels temperature difference; If by reducing the start-stop control temperature difference of compressor, make the high frequent start-stop, can reduce the fluctuation of temperature to a certain extent, but often power is very big because compressor is when just starting, frequent start and stop not only make the life-span of compressor be subjected to influencing greatly, and the power consumption of refrigerator is increased to some extent.Therefore, in the refrigerator of prior art, temporarily also fail science and reasonably solve the constant relatively problem of refrigerator temperature, the temperature difference is bigger in the case, is difficult to accurate temperature controlling.
The utility model content
The purpose of this utility model provides a kind of fresh-keeping energy-saving refrigerator of accurate temperature controlling, to solve the problem of being brought in the conventional art, provides a kind of fresh-keeping energy-saving refrigerator of energy accurate temperature controlling, makes refrigerator reach multiple effect fresh-keeping, energy-conservation, accurate temperature controlling simultaneously.
In order to achieve the above object, the technical scheme that the utility model adopted is:
The fresh-keeping energy-saving refrigerator of accurate temperature controlling comprises casing, door body, refrigeration system and control system with heat-insulation layer, and casing constitutes refrigerating chamber and refrigerating chamber with the door body, is provided with rack, fruit and vegetable box drawer and pallet in the refrigerating chamber, is provided with multi-layer drawers in the refrigerating chamber; Described refrigeration system comprises compressor, capillary, condenser, refrigeration evaporator, refrigerating evaporator; Described control system comprises master control borad, shows control plate, magnetic valve, temperature sensor, door lamp switch; Described refrigeration evaporator adopts the reverse-flow S shape of two-way aluminium coil pipe, and described refrigerating evaporator adopts the ρ shape wire-and-tube evaporator of non-homogeneous arrangement pipeline.
The fresh-keeping energy-saving refrigerator of described accurate temperature controlling, described refrigeration evaporator entrance and outlet section all are positioned at upper end of evaporator.
High-temperature region in the fresh-keeping energy-saving refrigerator of described accurate temperature controlling, described refrigerating chamber, the pipeline of ρ shape wire-and-tube evaporator is arranged close; Low-temperature space in the described refrigerating chamber, the pipeline of ρ shape wire-and-tube evaporator is arranged rare.
The fresh-keeping energy-saving refrigerator of described accurate temperature controlling is equipped with the temperature-sensitive head cover plate that adopts loose structure on the described temperature sensor; Described rack is evenly equipped with aperture near each side-walls of refrigeration chamber courage.
The fresh-keeping energy-saving refrigerator of the accurate temperature controlling that the utility model relates to, its described refrigeration evaporator adopts the reverse-flow S shape of two-way aluminium coil pipe, cold-producing medium from top to bottom flows into refrigeration evaporator by the evaporator inlet section earlier, after heat exchange, from bottom to top returns compressor from refrigeration evaporator outlet section bottom.Because evaporimeter aluminium coil pipe entrance sticks on the heat conduction aluminium sheet with the two-way parallel mode with outlet section, and aluminium coil pipe entrance is with outlet section flow of refrigerant direction difference, therefore can realize stronger heat exchange, thereby the temperature field of improving refrigeration evaporator heat conduction aluminium sheet distributes; Described refrigerating evaporator adopt non-homogeneous arrangement pipeline ρ shape wire-and-tube evaporator, the arrangement by adjusting wire-and-tube evaporator Bandaid pipe and the density mode of steel wire are carried out adequate compensation to height isothermal segment in the refrigerating chamber.
Be covered with the temperature-sensitive head cover plate of loose structure on the described temperature sensor, improve the temperature sensitivity of temperature sensor corresponding chamber; Rack is evenly equipped with aperture near each side-walls of refrigeration chamber courage, and the setting up of aperture on the shelf makes the cold air that originally might be detained in small space sink and roll mobilely, is unlikely to produce local temperature surfusion.
Compared with the prior art, the utlity model has following advantage:
1, the utility model adopts the evaporimeter of the reverse-flow S shape of two-way aluminium coil pipe and the ρ shape wire-and-tube evaporator of non-homogeneous arrangement pipeline, the temperature field that can effectively improve each chamber distributes and the cold distribution, thereby temperature is even everywhere in the maintenance case, more help the fresh-keeping storage of food, simultaneously can reduce refrigerator power consumption, make product energy consumption be better than GB 1 grade standard.
2, the utility model adopts the temperature-sensitive head cover plate and the rack of loose structure, can significantly reduce the temperature fluctuation of each chamber and the temperature difference in levels space, realizes the refrigerator accurate temperature controlling, and simple in structure, easy to implement.
