Abstract
The present invention provides a refrigerator with the power cut memory function. The present invention comprises a temperature control system. The present invention is characterized in that the temperature control system comprises a temperature judgment program with the power cut memory function. After the power is cut and is supplied again, the temperature control system collects the temperature T in the refrigerator at the moment by a temperature sensing element. On the basis of the temperature T, according to the preset judgment condition, the temperature judgment program automatically senses, judges and enters the temperature control state before the power cut or approaching to the power cut state to operate. The power cut memory time is long, and the present invention has no need of adding electronic elements of capacitors (or batteries), memory chips, etc., has low cost, and is accurate and reliable to control.
Description
Technical field
The invention belongs to refrigerator, is a kind of refrigerator with outage memory specifically.
Background technology
Present various electronic program control refrigerator is in order to satisfy the multipurpose function, and its temperature controllable scope is wide, and temperature is set and usually striden multiple functional status (generally stride refrigeration, littlely freeze, freezing function state).The default conditions that entered can only be wherein a certain functional statuses but machine powers on for the first time.
The outage memory function that general refrigerator uses is to realize the memory of certain hour by memory chip (providing the energy by battery or capacitor discharge).Electric capacity (or battery) capacity determines the length of memory time.Increase electronic components such as electric capacity (or battery), memory chip because of need, the cost height, and grow up to memory time originally high more more.Be subjected to cost impact, be generally about 2h its memory time.Adopt electric capacity (or battery), because electric capacity (battery) discharge has certain critical condition, if at the critical condition incoming call, will cause the temperature-controlling system disturbance of memory, the judgement that makes a mistake loses the memory of function, poor reliability in its memory process.Send a telegram here after existing refrigerator exceeds memory time, temperature-controlling system control automatically enters default conditions, and the range of set temperature of not necessarily starting shooting.Like this, food does not just reach predetermined refrigeration or refrigerating effect, even can damage, go bad.
Summary of the invention
The objective of the invention is to provide a kind of refrigerator with outage memory at the deficiencies in the prior art, its outage is longer memory time, need not to set up electronic components such as electric capacity (or battery), memory chip, cost is low, incoming call back temperature-controlling system can enter temperature (or near the temperature before the outage) the state of a control operation before the outage, precise control, reliable automatically.
The objective of the invention is to be achieved through the following technical solutions: a kind of refrigerator with outage memory, comprise temperature-controlling system, can carry out temperature to a preset temperature interval of selecting in a plurality of temperature ranges controls automatically, it is characterized in that containing in the described temperature-controlling system outage memory temperature decision procedure, job step is as follows:
When after the refrigerator outage, sending a telegram here again, temperature-controlling system is gathered temperature T in the refrigerator case this moment by temperature-sensing element, by outage memory temperature decision procedure according to this temperature T, judge by the decision condition of presetting which kind of default decision condition is temperature T satisfy, and make the temperature state of a control operation before refrigerator enters the preceding or approaching outage of outage.
When the present invention sent a telegram here after outage again, the job step of concrete outage memory temperature decision procedure was as follows:
When sending a telegram here again after the outage, the temperature T that temperature-controlling system is gathered in the refrigerator case by temperature-sensing element is judged, whether program judge T＞0 ℃, if temperature-controlling system enters the operation of artificial intelligence refrigeration state of a control, if not, whether program judge T≤-8 ℃, if temperature-controlling system enters the freezing state of a control operation of artificial intelligence, if not, temperature-controlling system enters-5 ℃ of design temperature state of a control operations.
When the present invention sent a telegram here after outage again, the job step of the concrete outage memory temperature decision procedure of another kind of refinement was as follows:
When sending a telegram here again after the outage, the temperature T that temperature-controlling system is gathered in the refrigerator case by temperature-sensing element is judged, whether program judge T＞0 ℃, if, temperature-controlling system enters the operation of artificial intelligence refrigeration state of a control, and if not, whether program judge T＞-3 ℃, if temperature-controlling system enters-5 ℃ of design temperature state of a control operations; If not, whether program judge T＞-8 ℃, if temperature-controlling system enters-8 ℃ of design temperature state of a controls operations, if not, enters the artificial intelligence freezing state.
The present invention compared with prior art has many advantages and good effect:
1, the present invention utilizes refrigerator design itself to have good heat-insulating property, the box house temperature is gone up to exceed certain warm area needs and is quite grown one (about 10 hours rise period after outage, even tens of hours) this characteristic, in temperature-controlling system, set certain decision procedure, when after outage, sending a telegram here again, temperature-controlling system is gathered temperature T in the refrigerator case this moment by temperature-sensing element, and according to temperature T, by default decision condition, the temperature state of a control operation of outage preceding (or before the most approaching outage) is responded to, judges and entered to program automatically.Its outage is longer memory time, need not increase elements such as electric capacity (or battery), memory chip, only increases decision condition and get final product in program, and is with low cost.
2, the actual temp value in the Yu She decision condition can be decided according to actual conditions, temperature range can be segmented as required, system running state can be to greatest extent near state before the outage when guaranteeing to send a telegram here again after the outage, precise control is reliable, reaches predetermined food refrigerated or refrigerating effect easily.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is the logic diagram of a kind of memory temperature decision procedure that cuts off the power supply of the present invention;
Fig. 2 is the logic diagram of the another kind of outage of the present invention memory temperature decision procedure.
The specific embodiment
Referring to Fig. 1, when sending a telegram here again after the outage, the temperature T that temperature-controlling system is gathered in the refrigerator case by temperature-sensing element judges, whether program judge T＞and 0 ℃, if, temperature-controlling system enters the operation of artificial intelligence refrigeration state of a control, and if not, whether program judge T≤-8 ℃, if, temperature-controlling system enters the freezing state of a control operation of artificial intelligence, and if not, temperature-controlling system enters-5 ℃ of design temperature state of a control operations.
Referring to Fig. 2, when sending a telegram here again after the outage, the temperature T that temperature-controlling system is gathered in the refrigerator case by temperature-sensing element is judged, whether program judge T＞0 ℃, if temperature-controlling system enters the operation of artificial intelligence refrigeration state of a control, if not, whether program judge T＞-3 ℃, if temperature-controlling system enters-5 ℃ of design temperature state of a controls operations; If not, whether program judge T＞-8 ℃, if temperature-controlling system enters-8 ℃ of design temperature state of a controls operations, if not, enters the artificial intelligence freezing state.
