Abstract
The invention relates to a refrigerator with variable freezing capacity, wherein an evaporator is respectively arranged in a refrigerating chamber and a freezing chamber, a main evaporator and an auxiliary evaporator are arranged in the freezing chamber, the branches of the main evaporator and the auxiliary evaporator are connected in parallel onto a main refrigerating loop comprising a compressor, a condenser and a capillary, and an electromagnetic valve is arranged on the branch of the auxiliary evaporator. The refrigerator has variable freezing capacity, the freezing capacity of the freezing chamber can be quickly improved under the working conditions of a large amount of stored foods and high temperature and can be adjusted under the conditions of a small amount of foods and smaller low-temperature working-condition loads, and the operating time of the compressor is reduced to reduce the energy consumption so that the refrigerator has higher energy-saving effect when in use.
Description
Technical field
The present invention relates to be used for the refrigerator refrigeration technology field, more particularly, relate to a kind of refrigerator of variable freezing capacity.
Background technology
The refrigerator of compressor cooling type is economical reliable with it, technical maturity, life-span are long, characteristics easy to use are in occupation of the most market share, it is made of critical components such as compressor, condenser, device for drying and filtering, capillary and evaporimeters, utilize the circulation of cold-producing medium to carry out heat exchange by refrigeration system, in the air of the transfer of heat in the refrigerator outside refrigerator, reach the purpose that makes cooling in the refrigerator.At present, refrigerator in use, the refrigerating capacity of refrigerator is constant substantially, user's food storage amount varies, if the refrigerating capacity of refrigerator is less, when the freezing a large amount of food of needs, icy ability can be not enough to some extent, make the temperature of food delay to lower, influenced the storage quality of food.If the food product refrigeration ability that the refrigerator design is bigger for the less occasion of food product refrigeration amount, can be wasted more electric energy, pay higher cost.The refrigeration system of this refrigerator adopts fairly simple control system usually, for example puts into food in certain warm area, may trigger refrigeration system again and start working, and causes the freeze space temperature low excessively, has influenced the storage quality of food.
Summary of the invention
The technical problem to be solved in the present invention is, at the deficiency that prior art exists, provides a kind of refrigerator of variable freezing capacity, to adapt to the needs of different occasions, reaches the effect of energy savings.
The technical solution used in the present invention is, the refrigerator of the discrete circulation of a kind of refrigerating chamber is provided, comprise the refrigeration system and the controller that constitute by compressor 1, condenser 2, capillary, evaporimeter, liquid reservoir 9, it is characterized in that, evaporimeter 5,6 and 7 is set respectively in three warm areas, the first, second, third refrigeration branch road that is made of three evaporimeter parallel connections is connected in parallel in the refrigerating circuit, also comprise the flow distributor that is subjected to described controller signals control in refrigerating circuit, flow distributor 4 is only connected one of them evaporimeter when compressor operating.
For solving the problems of the technologies described above, construct a kind of refrigerator of variable freezing capacity, in refrigerating chamber and refrigerating chamber, be respectively equipped with evaporimeter, in refrigerating chamber, be provided with main evaporator and auxiliary evaporator, described main evaporator and auxiliary evaporator branch road are connected in parallel on the refrigeration major loop of being made up of compressor, condenser, capillary, and described auxiliary evaporator branch road is provided with magnetic valve.
In the refrigerator of above-mentioned variable freezing capacity, described auxiliary evaporator comprises first auxiliary evaporator and second auxiliary evaporator, described first auxiliary evaporator and second auxiliary evaporator all are connected with magnetic valve, described first auxiliary evaporator and the second auxiliary evaporator parallel connection.
In the refrigerator of above-mentioned variable freezing capacity, described main evaporator is provided in a side of the tier rack type evaporimeter in the refrigerating chamber inner chamber, can place cold chamber drawer on each layer of main evaporator.
In the refrigerator of above-mentioned variable freezing capacity, described auxiliary evaporator is located between refrigerating chamber inner chamber and the adiabatic alveolar layer, and described auxiliary evaporator is attached on the sidewall of refrigerating chamber inner chamber.
Compared with prior art, refrigerator of the present invention has the following advantages:
The present invention improves the refrigeration system of existing refrigerator, and the user can regulate the refrigerating capacity of freezer chamber of refrigerator according to food storage amount size.By increasing second, third auxiliary evaporator, improve the refrigerating chamber refrigerating capacity, according to different operating positions, refrigeration cycle can be made accommodation, under the bigger situation of load, all can devote oneself to work in all discrete evaporimeter loops, system produces maximum refrigerating capacity, when load is less, can turn-off second, third auxiliary evaporator, only stay main evaporator to devote oneself to work, can reduce refrigerator power consumption, energy savings.
Description of drawings
Fig. 1 is the structural representation of the freezing chamber that freezes the ability refrigerator of turning cold of the present invention;
Fig. 2 is the refrigeration system schematic diagram that turns cold and freeze the ability refrigerator of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
The parts that each label is represented in the accompanying drawing are as follows:
1 compressor, 2 condensers
3 devices for drying and filtering, 4 magnetic valves
5 first auxiliary evaporators, 6 main evaporators
7 second auxiliary evaporators, 9 liquid reservoirs
Refrigeration system of refrigerator of the present invention constitutes closed circuit by compressor 1, condenser 2, filter 3, capillary, main evaporator 6, first auxiliary evaporator 5, second auxiliary evaporator 7, reservoir 9, Fig. 1 is the structure of refrigerator freezing chamber, be that the left and right sides that main evaporator 6 (refrigerating evaporator) is attached to freezing chamber is first, second auxiliary evaporator in freezing chamber, three evaporimeters are in parallel.
See Fig. 2, main evaporator 6, first auxiliary evaporator 5, second auxiliary evaporator 7 are refrigeration branch roads in parallel, are in series with magnetic valve 4 respectively on each evaporimeter branch road, are connected in parallel in the main refrigerating circuit again, form independently three evaporimeter refrigeration branch roads of parallel connection.As another kind of scheme, the magnetic valve that connects main evaporator can be cancelled.
The control system of refrigerator of the present invention comprises the break-make control to three branch roads arranged side by side, control system is provided with the gauge tap of magnetic valve 4, the user can manually opened first auxiliary evaporator 5 or the branch road of second auxiliary evaporator 7, also can open No. three evaporimeter loops simultaneously, make the refrigerating capacity of refrigerating chamber reach maximum rating.
Refrigerator storage temperature of the present invention adopts mechanical temperature-control control, and refrigerating chamber is according to the control of refrigerating chamber coupling.The present invention can improve the refrigerating capacity of refrigerating chamber rapidly, and under food and worst cold case were loaded less situation on a small quantity, refrigerating capacity can change.Because the evaporator operation of refrigerating chamber can be made accommodation according to the demand of cold, make and use energy-conserving and environment-protective more on the refrigerator simultaneously, meet green designing requirement.
