Abstract
The utility model discloses a multi temperature-zone converting double-door refrigerator. The double-door refrigerator comprises a freezing chamber and a refrigerating chamber. Evaporators are respectively arranged in the freezing chamber and the refrigerating chamber, and the evaporators are connected with a compressor and a condenser to form a refrigerating circuit. A circuit system comprises a refrigerating temperature controller, a compensation switch, a freezing temperature controller, a temperature control switch, a starter, a protector, a refrigerating lamp, a door lamp switch and a compensating heater. The double-door refrigerator is characterized in that: the refrigerating temperature controller, the compensation switch, the freezing temperature controller and the temperature control switch are connected with a power supply and the compressor in parallel; wherein the compensating heater is connected with the refrigerating temperature controller in parallel after being connected with the compensation switch in series; the double-door refrigerator can be converted from two temperature zones into another two temperature zones, so as to lead the refrigerator to be more practical; therefore, not only multiple needs of users are satisfied, but also the fresh-keeping problem of food is solved; moreover, electric energy is saved.
Description
Technical field
The utility model relates to a kind of refrigerator, belongs to household electrical appliance technical field, is specially a kind of many warm area conversion two-door refrigerators.
Background technology
At present, the two-door many warm areas refrigerator on the market is two-door two temperature single control 2 warm areas or two-door two control 3 warm areas, can not satisfy the needs of the many warm areas of user.And the above refrigerator of 4 warm areas mostly is computer control greatly, cost height and complicated operation.
The utility model content
The utility model provides a kind of many warm areas refrigerator with translation function, promptly is convertible into other 2 warm areas by 2 warm areas, makes refrigerator more practical, has not only satisfied user's multiple needs, and has solved the fresh-keeping problem of food, has also saved electric energy.
For achieving the above object, be achieved by the following technical solution:
A kind of many warm area conversion two-door refrigerators; include refrigerating chamber and refrigerating chamber; evaporimeter is set respectively in refrigerating chamber and the refrigerating chamber; evaporimeter and compressor; condenser connects and composes refrigerating circuit; Circuits System includes refrigeration thermostat; compensating switch; freezing temperature controller; temperature detect switch (TDS); starter; protector; the refrigeration lamp; door lamp switch; compensating heater; it is characterized in that: refrigeration thermostat; compensating switch; freezing temperature controller; temperature detect switch (TDS) is connected with compressor parallel with power supply; the refrigeration lamp; door lamp switch and circuit are connected in series, and are connected in parallel with refrigeration thermostat after wherein compensating heater is connected with compensating switch.
Compared to existing technology, advantage of the present utility model is:
1, function is suitable for, and select the more: 2 warm areas can convert other 2 warm area refrigerators to, and just 4 warm areas are changed mutually, and each warm area adapts to the storage needs of different food products.
2, simple in structure, easy to operate, cost is low, wherein refrigerating chamber adopt not have is regulated temperature controller, need not to regulate one-touch switch control, just can reach the conversion of many warm areas.
3, it is low to have an energy consumption: during conversion because the freezing higher temperature that do not need, the adiabatic bed thickness of refrigerating chamber, the control available machine time is short, downtime is long, energy-saving effect is obvious.
Description of drawings
Fig. 1 is a schematic diagram of refrigerating of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model;
Fig. 3 is a refrigerator conversion concrete operations schematic diagram of the present utility model.
The specific embodiment
In conjunction with the accompanying drawings the utility model is described further.
As shown in Figure 1, be refrigeration system of the present utility model, include compressor, left and right sides condenser, dew eliminating tube, refrigeration evaporator, refrigerating evaporator, device for drying and filtering, capillary and muffler, above-mentioned parts connect by series system.
As shown in Figure 2; circuit control system; include refrigeration thermostat 1, compensating switch 2, freezing temperature controller 3, temperature detect switch (TDS) 4, starter 5, protector 6, refrigeration lamp 7, door lamp switch 8, compensating heater 9; wherein refrigeration thermostat 1, compensating switch 2, freezing temperature controller 3, temperature detect switch (TDS) 4 are connected in parallel with power supply and compressor 10; refrigeration lamp 7, door lamp switch 8 are connected in series with circuit, are connected in parallel with refrigeration thermostat 1 after wherein compensating heater 9 is connected with compensating switch 2.
Many warm areas transfer principle has two states:
First kind of state: closing cold room temperature controller, connect freezing temperature controller, electrical system is connected, and refrigeration system is started working, freezing temperature controller is controlled at 12～15 ℃ (this temperature is fit to red wine and stores) with temperature of refrigerating chamber, and refrigerating chamber is-4～-7 ℃ (meat is cut immediately).Because temperature controller is controlled the freezing higher temperature that do not need of refrigerating chamber, the adiabatic bed thickness of refrigerating chamber is controlled the available machine time weak point during conversion, and downtime is long, and energy-saving effect is obvious.
Freezing temperature controller operating temperature characterisitic parameter is as follows: freezing temperature controller model: WPF12
Change freezing temperature controller control refrigerator temperature scope:
| Refrigerating chamber | Refrigerating | |
| Storage temperature | ||
| 12℃≤t 1，t 2，t 3≤15℃ | -4℃≤t 1，t 2，t 3≤-7℃ |
Second kind of state: close the refrigerating chamber temperature controller, connect refrigeration thermostat, electrical system is connected, and refrigeration system is started working, and refrigeration thermostat is controlled at 0～10 ℃ with temperature of refrigerating chamber, refrigerating chamber≤-18 ℃.
Refrigeration thermostat operating temperature characterisitic parameter is as follows: refrigeration thermostat model: WDF23
Conversion refrigeration thermostat control refrigerator temperature scope:
| Refrigerating chamber | Refrigerating | |
| Storage temperature | ||
| 0℃≤t 1，t 2，t 3≤10℃?t m≤5℃ | ≤-18℃ |
Can normally freeze at refrigerator under-10 ℃ of ambient temperature conditions: when environment temperature is lower than-10 ℃, open compensating switch, make temperature controller temperature-sensitive point reach start point temperature by compensating heater, thereby refrigerator is normally freezed.
As shown in Figure 3, for refrigerator conversion concrete operations schematic diagram, have soft freezing temperature detect switch (TDS) 11, temperature-compensating switch 12 and temperature controller release handle 13 in the refrigerator.
