Abstract
The invention relates to a defrosting heating device for an evaporator of a refrigerator and a control method. A plurality of independently controllable heaters are arranged on the evaporator. The heaters are connected in parallel. Each heater is provided with a corresponding temperature sensing probe. When defrosting is started, all heaters work at the same time; in the defrosting process, one heater is always kept to work and other heaters are turned on or off according to temperature sensed by the corresponding temperature sensing probes; and if the temperature sensed by the temperature sensing probes exceed first temperature T1, the corresponding heaters stop working, and if the temperature sensed by the temperature sensing probes is lower than second temperature T2, the corresponding defrosting heaters start to work. The defrosting heating device has the advantages that since the defrosting heaters and the temperature sensing probes are used, the heaters can realize time-sharing and sectional heating for defrosting and heat is concentrated at incompletely defrosted positions, the goal of complete defrosting is realized and the efficiency is high; and at the same time, the temperature on exit from a defrosting mode can be reduced and the problem that the internal temperature of the refrigerator is increased because of defrosting can be partially improved.
Description
Technical field
The invention belongs to the technical field of refrigerator, particularly a kind of defroster heating and control method that is used for evaporator of refrigerator.
Background technology
Wind cooling refrigerator generally all is to add a defrost temperature-sensitive head with a heater to the defrosting on the evaporimeter in the market; Often adopt overheated heating means in order to guarantee that the evaporimeter defrost is clean; Can go up because of refrigerator the temperature inside the box that the defrost heating causes; Defrost is withdrawed from temperature than higher, so not only wastes energy consumption but also can not guarantee the defrost effect of evaporimeter, and the heater life-span is short simultaneously.
Have in the prior art for wind cooling refrigerator evaporimeter and ponding dish and set up two defrosting heaters and a temperature-sensitive head separately, different heaters is opened in timesharing, can cut down the consumption of energy to a certain extent, but its solution is the problem that ponding dish trash ice is piled up.
In order to tackle frosting situation different on the evaporimeter targetedly, be necessary to seek a kind of efficient and defrosting device of cutting down the consumption of energy.
Summary of the invention
The problem that the present invention will solve is to provide a kind of efficient to the deficiency of prior art, and defroster heating and control method that frosting situation different on the evaporator of refrigerator defrosts are tackled in timesharing targetedly.
For solving the problems of the technologies described above, first technical scheme of the present invention is:
The present invention provides a kind of defroster heating that is used for evaporator of refrigerator, and the controlled heater of a plurality of independences is set on evaporimeter, and heater is for being connected in parallel, and each heater is provided with corresponding temperature-sensitive head separately.
Further, said heater compartment of terrain is fixed on the fin of evaporimeter, and the temperature-sensitive head compartment of terrain is fixed on the pipeline of evaporimeter.
Preferably, said heater one of them be positioned at the base of evaporator position.
Further, said heater is at least 3, and the quantity of temperature-sensitive head is corresponding with heater.Preferably, said heater and temperature-sensitive head respectively are 4.
Second technical scheme of the present invention is:
The above-mentioned control method that is used for the defroster heating of evaporator of refrigerator is provided, and when defrost began, institute's having heaters was started working simultaneously; In defrost process, one of them heater keeps duty always, and other heater then breaks off according to the temperature of the temperature-sensitive head perception of correspondence or be closed: set first temperature T 1 if the temperature of temperature-sensitive head surpasses, then corresponding heater quits work; Set second temperature T 2 if the temperature of temperature-sensitive head is lower than, then corresponding Defrost heater is started working.
Preferably, wherein keep the heater of work to be positioned at the base of evaporator position always.
Further, when the temperature of all temperature-sensitive heads all surpassed design temperature T1, the said heater of duty that in defrost process, always keeps just quit work.
Further, said first temperature T 1 is 12 ℃, and second temperature T 2 is 1 ℃.
Compared with prior art, the present invention has following beneficial effect:
The present invention utilizes a plurality of Defrost heaters and temperature-sensitive head, and heater is realized timesharing, segmentation heating defrost, and heat is concentrated on the sordid place of defrost, makes defrost clean, and is efficient; Simultaneously, can accomplish that reducing defrost withdraws from temperature, part is improved the refrigerator the temperature inside the box that causes because of defrost and is gone up.The present invention compares with similar defrost mode, can farthest utilize the heat of heater, improves the temperature recovery that causes because of defrost, cuts down the consumption of energy simultaneously.The heater life-span of the present invention is long, good reliability.
Description of drawings
Fig. 1 is Defrost heater of the present invention and the distribution map of temperature-sensitive head on evaporimeter;
Fig. 2 is Defrost heater control logic figure of the present invention.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is carried out detailed description.
As shown in Figure 1, the present embodiment defroster heating comprises four heater H 1 to H4, four temperature-sensitive head S1 to S4, four switches, switch 1 to switch 4.Heater H 1 to H4 by position shown in the figure, is fixed on the fin of evaporimeter 10, and temperature-sensitive head S1 to S4 also is fixed on the pipeline of evaporimeter 10 with band.Wherein, heater H 1 is positioned at the base of evaporator position.
As shown in Figure 2, with heater H 1 to H4 parallel connection, and respectively by the 4 control disconnections of switch 1 to switch, closure.
The control method of above-mentioned defroster heating is: the temperature through four temperature-sensitive head S1 to S4 detect is controlled cut-offfing of four heater H 1 to H4 respectively.When defrost begins; Heater H 1 to H4 is started working simultaneously; In defrost process, heater H 1 keeps the state of work always, and heater H 2 to H4 is then according to the temperature of temperature-sensitive head S2 to the S4 perception of correspondence; Break off or closure: if the temperature of temperature-sensitive head surpasses design temperature T1, then corresponding heater quits work; If the temperature of temperature-sensitive head is lower than design temperature T2, then corresponding heater is started working.
As all temperature-sensitive head S1 to S4 when satisfied temperature all surpasses design temperature T1 simultaneously, heater H 1 disconnection quits work.
Wherein heater H 1 is positioned at the base of evaporator position, and its basic demand is: other heater is all quit work, also can rely on heater H 1 basic effect of heating assurance defrost separately.
Above embodiment only is used to explain technical scheme of the present invention, but not to its restriction; Although the present invention has been carried out detailed explanation with reference to preferred embodiment; The those of ordinary skill in affiliated field is to be understood that; Still can specific embodiments of the invention make amendment or the part technical characterictic is equal to replacement; And not breaking away from the spirit of technical scheme of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
