Description
Affiliated technical field
The utility model relates to a kind of refrigerator, relates in particular to a kind of apparatus for controlling of refrigerant circulation of refrigerator.
Background technology
The existing refrigerator that is provided with new temperature band refrigerating chamber is that the refrigerator of-18～-3 ℃ of temperature controls adopts single cycle or binary cycle system usually, single round-robin system cooling system and double round robin cooling system refrigeration precision are inaccurate, temperature error is big, and the food fresh-keeping degree is bad, even causes food spoilage.For addressing the above problem, three circulatory systems that the manufacturer who has adopts, a kind of three circulating refrigerating devices are disclosed as Chinese patent 01279707, point out in the disclosed technical scheme in the specification of this patent document that three circulating refrigerating devices comprise compressor, condenser, magnetic valve, evaporimeter, the outlet of compressor connects the import of condenser, the outlet of condenser meets reversing solenoid valve A, one of them outlet of described reversing solenoid valve A connects reversing solenoid valve B, another outlet connects the inlet of evaporimeter A by capillary, and two outlets of described reversing solenoid valve B are connected with evaporimeter C with evaporimeter B by capillary respectively, after the outlet of two evaporimeter B that have the evaporimeter A of override control and preferentially control in described three evaporimeters was connected the import of the evaporimeter C with inferior preferential control, the outlet of passing through the evaporimeter C of lowest priority again linked to each other with the import of compressor.
Although can realize the temperature of chamber between three refrigerators in the technique scheme controls comparatively accurately, but because in this technical scheme, " outlet of self cooling condenser meets reversing solenoid valve A; one of them outlet of described reversing solenoid valve A connects reversing solenoid valve B ", be that reversing solenoid valve A is connected in series with reversing solenoid valve B, when magnetic valve A breaks down, whole cooling cycle system is ineffective, as can not in time fixing a breakdown, as user's long period of refrigerator outside, cause damage for the refrigerator user.
Summary of the invention
The utility model has overcome the shortcoming that the existing refrigerator that is provided with three circulating refrigerating devices exists, a kind of electric refrigerator with three-circulation refrigerating system that improves apparatus for controlling of refrigerant circulation is provided, this refrigerator in use, after the part control device breaks down, but other parts are operate as normal still, even can not in time get rid of breakdown of refrigerator, also can reduce refrigerator user's loss.
For solving the technical problem that the existing refrigerator that is provided with three circulating refrigerating devices exists, the utility model has adopted following technical proposals.
The utility model discloses a kind of apparatus for controlling of refrigerant circulation of refrigerator, this refrigerator comprises refrigerating chamber, refrigerating chamber and new temperature band refrigerating chamber; The compressor that is connected by the liquid pipe is set in the described refrigerator, condenser, capillary, refrigerator evaporator, new temperature band freezer evaporator, freezer evaporator and control refrigerator evaporator respectively, new temperature band freezer evaporator, the magnetic valve of freezer evaporator kind of refrigeration cycle, it is characterized in that: the liquid pipe that described flash-pot is drawn links to each other with the inlet of magnetic valve B with magnetic valve A respectively after being divided into two-way, the outlet of described magnetic valve A links to each other with refrigerator evaporator by capillary, the outlet of described magnetic valve B links to each other with new temperature band freezer evaporator by capillary, another outlet of described magnetic valve A links to each other with another inlet of described magnetic valve B by the liquid pipe, the liquid pipe of drawing on described magnetic valve A and the liquid pipe that magnetic valve B links to each other by capillary with behind refrigerator evaporator and liquid manifold collection that the outlet of new temperature band freezer evaporator is drawn, link to each other with freezer evaporator.
In the technique scheme, owing to meet magnetic valve A and magnetic valve B respectively after the liquid pipe that the outlet of flash-pot the is drawn shunt, link to each other by the liquid pipe with magnetic valve B owing to magnetic valve A again, therefore break down and when not working as electromagnetism A or magnetic valve B, but the magnetic valve that does not wherein break down is operate as normal still, two evaporimeters form kind of refrigeration cycle because magnetic valve A and magnetic valve B can be wherein respectively at least, therefore when one of them breaks down, can keep the temperature that suits between two of refrigerator in the chamber, avoid storing the food spoilage in this chamber, reduce refrigerator user's loss.
On the liquid pipe before the shunt that common described evaporimeter and described flash-pot are drawn device for drying and filtering is set.
Description of drawings
Fig. 1 is the structural representation that is provided with the refrigerator control endless form specific embodiment of three-circulation refrigerating system.
The specific embodiment
Three circulation refrigeration system of refrigerator as shown in Figure 1, refrigeration system comprises the compressor 1 that is connected successively by the liquid pipe, condenser 2, device for drying and filtering 3, the liquid pipe that self-desiccation filter 3 is drawn is divided into two-way, one the tunnel is connected with the inlet of magnetic valve A41, another road links to each other with the inlet of magnetic valve B42, the outlet of magnetic valve A41 links to each other with refrigerator evaporator 5 by capillary 51, the outlet of magnetic valve B42 links to each other with new temperature band freezer evaporator 6 by capillary 61, another outlet of magnetic valve A41 links to each other with another inlet of magnetic valve B42 by the liquid pipe, from the liquid pipe 11 of drawing on magnetic valve A and the liquid pipe 10 that magnetic valve B links to each other by capillary 71 with behind refrigerator evaporator and liquid manifold collection that new temperature band freezer evaporator is drawn, link to each other with freezer evaporator 7, the liquid pipe of drawing from freezer evaporator 7 and the inlet of compressor 1 are connected to form refrigeration cycle.
Refrigerator is when refrigeration in the above-mentioned specific embodiment, by control circuit control magnetic valve A, B, refrigerator evaporator 5 is preferentially freezed, because refrigerator evaporator 5 links to each other with freezer evaporator 7, therefore in to the refrigerating chamber refrigeration, also be the refrigerating chamber refrigeration, having time new temperature band freezer evaporator 6 of preferential control refrigeration simultaneously links to each other with freezer evaporator 7 equally, therefore when giving new temperature band refrigerating chamber refrigeration, also be the refrigerating chamber refrigeration, when refrigerating chamber with after newly temperature band refrigerating chamber reaches the control temperature, can be refrigerating chamber refrigeration so refrigerator temperature precise control separately by control circuit control.
In the above-mentioned specific embodiment, because magnetic valve A and magnetic valve B parallel connection, when one of them magnetic valve breaks down, the magnetic valve that does not break down still can be refrigerating chamber and one of them chamber refrigeration of new temperature band refrigerating chamber, and be the refrigerating chamber refrigeration simultaneously, therefore in the loss that does not have in time to find can reduce under the situation of breakdown of refrigeration system the refrigerator user.
The above-mentioned specific embodiment is not the qualification to the utility model protection domain, and according to inventive concept of the present utility model, the specific embodiment can be done various variations.
