Abstract
The utility model discloses an improvement to the refrigerator that current unit double capillary refrigeration control system constitutes. The refrigerator is characterized in that a change-over switch (11) is arranged in the control system and is respectively connected with the electromagnetic valve (4) and the refrigeration temperature controller (7), so that the refrigeration function is switched, the storage capacity of frozen food is improved, and the refrigerator is convenient for users to use.
Description
The utility model is a kind of refrigeration control system that is used for refrigerator.
At present, the direct-cooling type double-door and dual-temperature refrigerator in the society mainly contains two types.A kind of is the single press single loop system that is suitable for less freezing volume, and another kind is the double-pressing machine binary cycle system that is suitable for bigger freezing volume.Chinese patent discloses a kind of refrigerating system of single press double capillary closed circuit for No. 89205679.7, has solved the difficult problem that single press is realized big freezing volume refrigerator." Qindao-Liebherr " board BCD-220 type refrigerator is exactly a typical products of using this technology.Though this product has bigger refrigerating chamber, but still can not satisfy consumer's demand to freezing compartment during the Spring Festival.The consumer presses for a kind of freezing volume at the 50-100 liter, and freezing under special circumstances volume can reach more than 100 liters, even the double-door refrigerator of 200 liters.
It is a kind of simple in structure that the purpose of this utility model just is to provide, and installs easily, easy and simple to handle, refrigerating chamber can be switched to the New Refrigerating control system of refrigerating chamber under special circumstances.
The utility model is achieved in that in the refrigerating circuit of being made up of compressor, condenser, device for drying and filtering, evaporimeter, be serially connected with a two-position three way magnetic valve, two ports of export of magnetic valve link to each other with two capillaries respectively, and two capillaries link to each other with refrigeration evaporator with freezing respectively.
In the control system of forming by compressor, freezing temperature controller, refrigeration thermostat, magnetic valve, be serially connected with a change-over switch, the one end is connected with magnetic valve, and the other end is connected with refrigeration thermostat.
Owing to adopt technique scheme, both can realize the function of common double door refrigerator, can temperature of refrigerating chamber be controlled at below 0 ℃ by change-over switch again, increased the ability of freezer storage frozen food.
Be described further below in conjunction with accompanying drawing.
Accompanying drawing one is for using refrigeration system circulation schematic diagram of the present utility model.
Accompanying drawing two is for using change-over circuit schematic diagram of the present utility model.
Part in addition in the accompanying drawing is numbered (1) compressor, (2) condenser, (3) device for drying and filtering, (4) magnetic valve, (5) I capillary, (6) refrigeration evaporator, (7) refrigeration thermostat, (3) II capillary, (9) refrigerating evaporator, (10) freezing temperature controller, ［ 11 ］ change-over switch.
Referring to accompanying drawing, when change-over switch ［ 11 ］ was connected, the duty of magnetic valve (4) was by refrigeration thermostat (7) and freezing temperature controller (10) control.At this moment, if temperature of refrigerating chamber does not reach requirement, refrigeration thermostat (7) is failure to actuate, magnetic valve (4) is not being worked under the electriferous state, and cold-producing medium is walked the I road, after temperature of refrigerating chamber reaches requirement, refrigeration thermostat (7) action, magnetic valve (4) commutation is worked under electriferous state, and cold-producing medium is walked the II road.
When change-over switch ［ 11 ］ disconnects, magnetic valve (4) is not controlled by temperature controller, be in not electriferous state forever, cold-producing medium is walked the I road, even after temperature of refrigerating chamber reaches requirement, magnetic valve (4) does not commutate yet, compressor (1) still works on, make freezer temperature continue to descend, finally reach freezing temperature controller (10) the fixed temperature requirement of taking the photograph, the temperature of refrigerating chamber will be controlled in below 0 ℃ this moment.Frozen food all can be stored in the chamber between two of whole refrigerator.
Claims (3)
1, a kind of double capillary refrigeration control system, comprise compressor (1), condenser (2), device for drying and filtering (3), magnetic valve (4), I capillary (5), II capillary (3), refrigeration evaporator (6), refrigerating evaporator (9), refrigeration thermostat (7), freezing temperature controller (10) is characterized in that having in the control system change-over switch [11].
2, refrigeration control system according to claim 1 is characterized in that change-over switch ［ 11 ］ one ends are connected in magnetic valve (4), and the other end links to each other with refrigeration thermostat (7).
3, refrigeration control system according to claim 1 is characterized in that temperature controller (7) is the frozen type temperature controller for refrigeration-type temperature controller, temperature controller (10).
