Abstract
A temperature control system for the freezing chamber of a refrigerator comprises a refrigerating chamber temperature sensor for detecting the temperature of the refrigerating chamber, wherein the refrigerating chamber temperature sensor includes a single-pole double-throw switch contact KJ2. The contacts (a, c) of the KJ2 serially arranged in a compressor power circuit are connected when the temperature of the refrigerating chamber rises to a set value, and the contacts (a, b) of the KJ2 serially arranged in the power circuit of an electrothermal temperature compensating device are connected when the temperature of the refrigerating chamber decreases to a value smaller than the set value. The temperature control system is characterized in that a freezing chamber temperature sensor is arranged so as to detect the temperature of the freezing chamber, wherein a contact KJ1 of the freezing chamber sensor is serially connected with the power circuit of the electrothermal temperature compensating device (L); and the contact KJ1 is closed when the temperature of the freezing chamber rises to a set valve. The temperature control system can control the temperature of the freezing chamber directly, and can switch the electrothermal temperature compensating device according to requirement, thereby solving the problem in starting the refrigerator in winter and obviating power waste.
Description
Technical field
The utility model relates to the refrigerator temperature control system.
Background technology
At present, the temperature controller of household electric refrigerator all is arranged in the refrigerating chamber, with the temperature of refrigerator temperature sensor direct detection refrigerating chamber, and implements control according to this.And the temperature of refrigerating chamber is passive.In winter, though be provided with temperature compensation means in refrigerating chamber, temperature-compensating is very limited, often still because the temperature of refrigerating chamber can not rise to the temperature that freezer compressor is started, cause compressor to start, the quality of frozen food can not be guaranteed.
In actual the use, also exist the user and can not in time open the temperature-compensating switch in winter, and to summer fail timely closing temperature compensating switch, the former may not start the direct food quality that influences because of compressor, and the latter can cause waste of energy.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of freezer compartment of refrigerator temperature control system is provided, solve refrigerator startup in winter problem on the one hand, avoiding causing waste of energy on the other hand.
The utility model technical solution problem adopts following technical scheme:
System's setting of the utility model freezer compartment of refrigerator temperature control system comprises a refrigerator temperature sensor, be used to survey temperature of refrigerating chamber, described refrigerator temperature sensor has single-pole double-throw switch (SPDT) contact KJ2, be elevated to when setting value at temperature of refrigerating chamber, its series connection is arranged on contact ac closure in the electric power loop of compressor M; Return at temperature of refrigerating chamber and to drop to setting value when following, its series connection is arranged on the contact ab closure in the electric heating temperature compensation device L electric power loop.
Design feature of the present utility model is that a freezer temperature sensor is set, and is used to survey freezer temperature, is arranged in the electric power loop of electric heating temperature compensation device L with the contact KJ1 of described refrigerating chamber sensor series connection; When freezer temperature is elevated to setting value, contact KJ1 closure.
The utility model is to increase freezer temperature sensor contact KJ1 is set in the electric power loop of existing electric heating temperature compensation device L; and suitably strengthen the electric thermal power of electric heating temperature compensation device L; be higher than in the temperature of refrigerating chamber temperature is set; simultaneously; compressor is under the stopped status, and electric heating temperature compensation device L devotes oneself to work, and improves temperature of refrigerating chamber rapidly; make refrigerator temperature sensor detect this temperature regime, make compressor start.Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model is directly controlled freezer temperature, and as required the electric heating temperature compensation device is carried out switching, has both solved refrigerator startup in winter problem, has avoided causing waste of energy again.
Description of drawings
Fig. 1 is the utility model structural representation.
Below by the specific embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.
The specific embodiment
Referring to Fig. 1, present embodiment is to be provided with in the refrigerator temperature control system, be provided with routinely and comprise a refrigerator temperature sensor, be used to survey temperature of refrigerating chamber, refrigerator temperature sensor has single-pole double-throw switch (SPDT) contact KJ2, be elevated to when setting value at temperature of refrigerating chamber, its series connection is arranged on contact ac closure in the electric power loop of compressor M; Return at temperature of refrigerating chamber and to drop to setting value when following, its series connection is arranged on the contact ab closure in the electric heating temperature compensation device L electric power loop.
In the present embodiment, on the basis of conventional system, increase a freezer temperature sensor is set, be used to survey freezer temperature, be arranged in the electric power loop of electric heating temperature compensation device L with the contact KJ1 series connection of refrigerating chamber sensor; When freezer temperature is elevated to setting value, contact KJ1 closure.
In concrete the enforcement, because just reaching at freezer temperature, electric heating temperature compensation device L devotes oneself to work just now when being elevated to by controlling temperature, therefore, the 2-3 that can be directly the electric thermal power of electric heating temperature compensation device L be suitably added greatly existing refrigerator temperature sensor electrical thermal power doubly can quickly and reliably compensate refrigerated storage temperature like this.
Working condition:
Freezer temperature remains on below the control temperature of setting, and the contact KJ1 of freezer temperature sensor cut-offs, and the electric power loop of electric heating temperature compensation device L cut-offs;
When temperature of refrigerating chamber remains within the design temperature; compressor shutdown; the contact ac of contact KJ2 disconnects; the ab closure; at this moment; when if freezer temperature rises to the control temperature of setting; the contact KJ1 closure of freezer temperature sensor, the electric power loop of electric heating temperature compensation device L is connected, and electric heating temperature compensation device L devotes oneself to work; the refrigeration indoor temperature improves rapidly thereupon; by this temperature of refrigerator temperature sensor perception, and with the contact ac closure of the contact KJ2 of refrigerator temperature sensor; ab disconnects, compressor start; system enters the refrigeration work state; simultaneously, owing to cut-offfing of ab, the electric power loop of electric heating temperature compensation device L is cut off.
