Abstract
The utility model relates to a refrigerator, in particular to a refrigerator with an electric heater, which can effectively provide multi-level protection for the heater. The refrigerator comprises a heater, a heater switch, a temperature limiting switch, a compressor and a compressor switch, wherein the compressor switch and the compressor are connected in series, the heater switch, the temperature limiting switch and the heater are connected to form a heater branch, the heater branch is connected in parallel with the two ends of the compressor, and one end of the heater is connected between the compressor switch and the compressor. The utility model is suitable for the single system, the dual-temperature zone or the multi-temperature zone of the refrigerator for high cooling capacity. The electric heater is adhered to the refrigeration evaporator.
Description
Technical field
The utility model relates to a kind of refrigerator, specifically, relates to a kind of refrigerator that electric heater is set.
Background technology
Electrical heating is very crucial parts on the refrigerator, and universal design is that the electricity consumption heater switch is directly controlled electrical heating, and stricter requirement is thermoswitch or the fuse that one of serial connection plays the effect of limit temperature on the electrical heating loop.If this heater circuit switch damages, protect badly will cause that heating causes food to degenerate unusually, even the more serious generation that causes fire.Therefore, the quality to the electrical heating protection is one of key factor that causes the generation of refrigerator significant trouble.
Summary of the invention
The purpose of this utility model is to overcome above defective, and a kind of refrigerator that the electric heater that multiple protective is set can be provided for refrigerator heater effectively is provided.
The technical scheme that the refrigerator of the electric heater of being with multiple protective is set of the present utility model is such: it comprises heater, heater button, temperature limit switch, compressor, compressor switch; compressor switch and compressor series connection; heater button, temperature limit switch and heater are connected the back and form the heater branch road; the heater branch road is connected in parallel on the two ends of compressor, and heater one end is connected between compressor switch and the compressor.
The refrigerating circuit of mechanical refrigerator of the present utility model, in the process of carrying out the refrigerator refrigerating capacity, in the process of press start, make the auxiliary electrical heating work simultaneously, improve the temperature of refrigerating chamber, prolong the available machine time of compressor, the temperature of refrigerating chamber can be lowered the temperature always, thereby reach the effect that improves refrigerating capacity.Solved the general big inadequately problem of this mechanical type refrigerator refrigerating capacity.
Description of drawings
Fig. 1 is the structural representation of the refrigerating circuit of mechanical refrigerator of the present utility model.
The specific embodiment
As shown in Figure 1; of the present utility model be provided with the band multiple protective electric heater refrigerator it comprise heater R, heater button K2, temperature limit switch K3, compressor M, compressor switch K1; compressor switch K1 and compressor M series connection; heater button K2, temperature limit switch K3 are connected the back and form the heater branch road with heater 4; the heater branch road is connected in parallel on the two ends of compressor M, and heater R one end is connected between compressor switch K1 and the compressor M.
On hardware, electrical heating K switch 2 is concatenated in the loop of compressor switch K1, necessary the compressor M that whether works also of electrical heating R works like this, in the time of electrical heating R work, compressor M is simultaneously in refrigeration, when design guaranteed compressor M work, the heating temp of electrical heating R was in the safe temperature scope.The work of electrical heating R is compressed the restriction that machine M must work like this, and simultaneously, the switch of control electrical heating R must be opened, and plays the K switch 3 of limit temperature effect or three kinds of guarantees that fuse must be connected.
On software, detect electrical heating, when electrical heating reaches the heating-up temperature of setting, close electrical heating.Simultaneously, the electrically heated whole maximum operating time is limited, be operated in the time of qualification when electrical heating after, no matter whether temperature reaches the positive closing electrical heating.And if the electrical heating temperature sensor breaks down, mandatory requirement is closed electrical heating.
The design is fit to be applied to the occasion of refrigerator single system, two warm area or the big refrigerating capacity of many warm areas requirement.Electrical heating is attached on the refrigeration evaporator.
