Description

The control panel of refrigerator

The utility model relates to the household electrical appliance parts, more clearly says so to be used on the refrigerator control panel to its refrigerator of controlling.

The old-fashioned refrigerator in past, the temperature of its refrigerating chamber and refrigerating chamber are to be controlled by the temperature controller that is installed on the refrigerating chamber sidewall.The setting of general temperature is divided into 1 to 5 grade cursorily, and the temperature in the refrigerator is gradually low successively.The user can transfer temperature controller on different gears according to the needs of oneself.The setting of this temperature is not only coarse, precision is low, and will open refrigerator and could regulate, and is very inconvenient.In addition, how many temperature of refrigeration formula and refrigerating chamber is actually, can not measure, and can not show.Occurred control panel in recent years and be positioned at refrigerator on the shell, the regulation and control of its temperature and the switch of refrigerator use all very convenient.But the setting of temperature is still coarse, and still can not show the actual temperature of refrigeration and refrigerating chamber.

The purpose of this utility model, be to overcome above-mentioned shortcoming deficiency, thereby provide a kind of being installed in to be convenient to the operation regulation and control on the outer case of refrigerator, the actual temperature of refrigerating chamber and refrigerating chamber shows that with numeral the temperature of refrigerating chamber and refrigerating chamber can be by the control panel of the refrigerator that once increased and decreased setting.

In order to achieve the above object, the utility model by the panel on the shell that is installed in refrigerator, be installed in be positioned at the wiring board of panel back on the shell of refrigerator and be installed in wiring board and panel on electronic circuit constitute.A transparent face mask is installed on the panel, and five displays and a locking indicator lamp of electronic circuit are positioned at the transparent face mask back.Power button, quick-frozen button, temperature setting or display button, the refrigeration setting value that electronic circuit also is installed on the panel adds a button, refrigeration setting value and subtracts that a button, freezing setting value add a button, freezing setting value subtracts one by subtracting key and being positioned at power button and the power supply indicator and the quick-frozen indicator lamp of quick-frozen button top.

Electronic circuit link to each other with three indicator light circuits, with singlechip controller by five displays that are installed in two temperature sensors in refrigerating chamber and the refrigerating chamber, the singlechip controller that links to each other with temperature sensor, the key control circuit that links to each other with singlechip controller respectively, link to each other with singlechip controller and and then the relay drive circuit that links to each other with magnetic valve with compressor and the power circuit of powering to above-mentioned circuit appliance constitute.Singlechip controller is made of DIP281 type single-chip microcomputer.Key control circuit has power button, quick-frozen button, temperature setting or display button, refrigeration setting value to add a button, refrigeration setting value to subtract that a button, freezing setting value add a button, freezing setting value subtracts a button totally 7 buttons.Three indicator light circuits comprise power supply indicator, quick-frozen indicator lamp and locking indicator lamp.

During use, pinned power button 3 seconds, then close general supply, all indicator lamps extinguish, and refrigerator is shut down.Click power button again, power connection then, the relay drive circuit is connected compressor and magnetic valve, and refrigerator recovers normal operating conditions.

Press the quick-frozen button, the quick-frozen indicator lamp is bright, and refrigerating chamber enters the quick-frozen state.By a quick-frozen button, the quick-frozen indicator lamp goes out again, and refrigerating chamber withdraws from the quick-frozen state.Pin this key 3 seconds continuously, can between quick-frozen and non-quick-frozen, change.

Press quick-frozen button and temperature simultaneously and set or display button, then show " CC ".As pressing simultaneously 3 seconds, it is bright then to lock indicator lamp, and temperature value is locked, adds one or to subtract a button all reactionless by any refrigeration or freezing setting value again.Pressed simultaneously 3 seconds, the locking indicator lamp goes out again, and lock-out state is disengaged.

At unlock state, press that temperature is set or display button, five displays then show refrigeration, freezing design temperature.From left to right, the front two of five displays is the refrigerated storage temperature number of degrees, and middle one is the negative sign of cryogenic temperature, and back two is the cryogenic temperature number of degrees.Change design temperature as need, whenever click the refrigeration setting value and subtract a button, the refrigeration setting value then once subtracts.Touch the bottom 2 ℃ the time, then reactionless by this key again.Whenever add a button by once refrigeration setting value, the refrigeration setting value then once adds.Peak 9 ℃ the time, show " EE " by this key again, the expression refrigerating chamber is closed.Continue by this key then reactionless this moment.Whenever click freezing setting value and subtract a button, freezing setting value once subtracts.When reaching minimum-31 ℃, then reactionless by this key again.Whenever click freezing setting value and add a button, freezing setting value once adds.When reaching peak-18 ℃, then reactionless by this key again.If do not make the temperature setting operation in 30 seconds, then recovery temperature shows automatically.As set by temperature again or display button once, but also displays temperature.Five displays this moment front two demonstration from left to right refrigerating chamber actual temperature, back two demonstration refrigerating chamber actual temperatures, middle one is negative sign, the expression freezer temperature is subzero.When above-mentioned button operation, whenever click effective key, all be attended by buzzer toot one.Buzzer links to each other with power supply with singlechip controller.

After refrigeration and freezing setting value were set, refrigerator was just carried out this instruction.At this moment, two temperature sensors that are arranged in refrigeration formula and refrigerating chamber are delivered to five displays demonstrations with temperature value through singlechip controller on the one hand, on the other hand temperature value is sent singlechip controller and setting value to compare, comparison signal passes through the relay drive circuit by singlechip controller operation back, send operational order to compressor and magnetic valve, refrigerator is finished regulation and control.The core of this electronic circuit is a DIP281 type single-chip microcomputer, and its CPU is the intelligent centre of whole circuit.

Task of the present utility model comes to this and finishes.

The utility model provides a kind of control panel of intelligentized refrigerator.It is installed on the shell of refrigerator, operates, regulates and control very convenient.Its refrigeration and the setting value of cryogenic temperature and actual value all can charactron or the demonstrations of LCD numeral, and be fully aware of, accurate, eye-catching.Refrigeration and cryogenic temperature setting value can once increase and decrease, and accurately made things convenient for.It can be widely used in refrigerator, ice box and other is with in the electric appliances.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further narration.
