Abstract
The utility model relates to an automatic refrigerator temperature compensating device and is characterized in that a low temperature chamber of the refrigerator is provided with an automatic on-off temperature detection switch which is connected in series with a compensating heater to form an automatic compensating branch circuit. The utility model automatically controls the operation of the compensating heater according to the temperature in the low temperature chamber, which effectively improves the response characteristics of a refrigerator temperature control system to food storage and fetching, increases response rate and dramatically improves the self adaptation capability of the refrigerator temperature control system in low environment temperature. The utility model reduces energy consumption and ensures food storage quality.
Description
Technical field:
The utility model relates to the refrigerator temperature control device.
Background technology:
Refrigerator of the prior art, because the irrationality that the attemperating unit structure is provided with is brought following problem:
1, the conventional refrigerator that is provided with is that the leading portion with evaporimeter is that refrigerating chamber or ice greenhouse freeze to chamber between low temperature, and the back segment with evaporimeter freezes to refrigerating chamber simultaneously.And the temperature-sensitive of its temperature control equipment point is arranged in the refrigerating chamber.When we will put between low temperature behind the chamber near the food of environment temperature, the temperature of condenser, evaporimeter can raise suddenly, the back segment that is positioned at the evaporimeter of refrigerating chamber will be in superheat state in a period of time, thereby the working time of compressor prolongs, cause the overshoot of refrigerator temperature-controlling system to increase, not only bring the loss of energy, and the food in the refrigerating chamber often is damaged by frost in this process.
2,, when the environment for use temperature is low, can cause the rising of its low temperature room temperature degree because compressor is shut down for a long time because the temperature-sensitive point of attemperating unit is arranged in the refrigerating chamber, and the Homes Using TV of freezer compressor can be followed the reduction of environment temperature and be descended.In order to satisfy the low temperature requirement of chamber between low temperature, compensating heating device is set, enter after winter, compensating heating device is opened in the requirement of user's palpus by specification, the refrigerator Homes Using TV is risen, to keep freezing low temperature.And after environment temperature raises, again compensating heating device is closed.This compensation mode of heating makes cryogenic temperature cross low and increases power consumption.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid existing weak point in the above-mentioned prior art, provide a kind of refrigerator temperature autocompensation installation, to improve the freezer temperature control system to the response characteristic of access food operation and to hanging down the adaptive ability of environment for use temperature.
Design feature of the present utility model is the indoor temperature inspection switch that auto switching is set between refrigerator low temperature, and described temperature inspection switch is connected with compensating heater to be provided with and constituted compensation branch road automatically.
Compared with the prior art, the beneficial effects of the utility model are embodied in: the utility model utilization has the auto switching temperature inspection switch of high temperature conducting low temperature disjunction function, and its reasonable Arrangement is indoor between low temperature, and the setting of connecting with compensating heater.Automatically control the working condition of compensating heater according to the temperature of chamber between low temperature.When temperature indoor between low temperature is raised to temperature inspection switch start point, because the conducting of temperature inspection switch, the compensating heater that is located in the refrigerating chamber will be connected automatically, the service factor of refrigeration system increases thereupon, realized the quick response of system, owing to the effect of compensating heater, the temperature of refrigerating chamber was unlikely to low, and had limited the overshoot of system simultaneously.When environment temperature is low,, avoided existing compensation mode of heating to make cryogenic temperature cross low and defective increase power consumption because the rising of refrigerator low temperature room temperature degree can excite the compensation arrangement self-starting equally.
The drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is another embodiment structural representation of the utility model.
The specific embodiment:
Present embodiment is the indoor temperature inspection switch WJ that auto switching is set between refrigerator low temperature, and this temperature inspection switch WJ has the switching function of high temperature conducting low temperature disjunction.Temperature inspection switch WJ connects with compensating heater BJ to be provided with and constitutes compensation branch road automatically.WJ controls the working condition of compensating heater BJ automatically according to the temperature of chamber between low temperature by temperature inspection switch, and then passes through freezer temperature control device WK control compressor bank working condition.Improve the freezer temperature control system effectively to the response characteristic of access food operation and to hanging down the adaptive ability of environment for use temperature.
Embodiment shown in Figure 1 is to compensate branch road automatically and freezer temperature control device WK branch road is arranged in parallel in same electric power loop.When temperature controller WK connected, compensating heater BJ was not because of being worked by short circuit; Compensation circuit is controlled by temperature inspection switch WJ during temperature controller WK disjunction.The characteristics of this version are to make the freezer temperature control system have the adaptive ability of low environment for use, and the disturbance rejection ability of system is strong.
Embodiment shown in Figure 2 is to compensate branch road and freezer temperature control device WK branch road automatically independently to be arranged in separately the electric power loop.Compensating heater BJ in this version is not subjected to the influence of temperature controller WK duty, and the overshoot that can more effectively control system is to guarantee the memory requirement of chilled food.
