Abstract
A main controller of a refrigerator. It is panel type, can be installed in the refrigerator or on the door of the refrigerator, and is convenient and beautiful to use. It is composed of casing, control circuit, panel, control key switch and LED display. The key switches and the light emitting diodes can be respectively provided with 3 keys and are respectively used for controlling and displaying a power supply, temperature acousto-optic alarm and low-temperature compensation and switching a refrigerating chamber into a freezing chamber. There may be 4 each, and the control and display of quick freezing are increased. It has multiple functions, long service life and high reliability. Can be widely applied to various refrigerators.
Description
The utility model relates to the refrigerator master controller, more clearly says so to be used for refrigerator it is controlled to finish the refrigerator master controller of various functions.
The control of refrigerator mainly relies on temperature controller.In the past, the temperature controller that refrigerator adopts mainly contains three kinds: double-metal sheet type, pressure type and electronic type.The bimetal chip thermostat structure is simpler, but temperature control is more coarse, and unreliable.The electronic temperature controller temperature control is more accurate, but reliability is still not high.Compression-type temperature controller is more reliable, uses quite general.But its structure, function are all fairly simple, and the function ratio that wants to further expand refrigerator is difficulty, is subjected to the restriction of master controller self.In addition, the refrigerator master controller in past adopts the neon bulb display working condition, and the service life of neon bulb is short, fragile.This will often change neon bulb, bring inconvenience to the consumer.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, provides a kind of control function more, and control accuracy is higher, and reliability is higher, and duty shows longer, not fragile, multi-functional, easy to use refrigerator master controller in service life.
In order to achieve the above object, the utility model refrigerator master controller by shell, be installed in the control circuit in the shell, gauge tap and the display element that is installed on the shell constituted.The shell front is installed with panel, and gauge tap and display element are installed on the panel.In other words, it is the panel type structure.Display element is made up of light emitting diode, and gauge tap is made up of key switch.This panel type structure both can be installed in the refrigerator, also can be directly installed on the Qianmen of refrigerator, can operate control easily, also was convenient to expand the function of control.
Key switch and light emitting diode respectively have 3, are respectively applied for control and display power supply, temperature alarming and low temp compensating and refrigerating chamber are transferred to the switch operating state of refrigerating chamber.The service life of light emitting diode is very long, replaces neon bulb as display device with it, and is not fragile, needn't often change, and reduced many troubles.Compare with the like product in past, the utility model expansion has increased temperature sound and light alarm and low temp compensating and refrigerating chamber has been transferred to the handoff functionality of refrigerating chamber.Control circuit of the present utility model is exactly in order to finish above-mentioned power supply, temperature sound and light alarm and low temp compensating and refrigerating chamber to be transferred to the control and the demonstration of 3 kinds of functions of switching of refrigerating chamber.Its control circuit can have various design.Key switch and light emitting diode also can respectively have control respectively and display power supply, temperature alarming, low temp compensating and refrigerating chamber is transferred to the switching of refrigerating chamber and 4 of quick-frozen.In fact, this has increased quick-frozen function and demonstration thereof again.
Consider that the user uses the needs of refrigerator winter, refrigerator generally all is equipped with the low temp compensating heater.The low temp compensating function can make refrigerator reach refrigerating effect preferably.When room temperature below 10 ℃ the time, the user just can start this key switch.This key switch can realize refrigerating chamber is transferred to the switching of refrigerating chamber simultaneously, to satisfy the needs that the user increases refrigeration content.
Task of the present utility model comes to this and finishes.
The utility model has 3 kinds or 4 kinds to control and Presentation Function, and function is many.Its temperature control precision is higher, and high reliability is arranged.The display device long service life, not fragile.Compare in the past, prolonged 1～3 times its service life.It uses reliable, convenient, can be widely used in the various refrigerators.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the panel schematic diagram of embodiment 2.
Fig. 3 is the electrical schematic diagram of embodiment 1.
Fig. 4 is the connection diagram of the utility model and refrigerator.
Shown in Figure 1, embodiment 1 is made of shell 1, control circuit 2, gauge tap 3,4,5, display element 6,7,8, panel 9. Display element 6,7,8 is a light emitting diode, and gauge tap 3,4,5 is a key switch.Gauge tap 3,4,5 and light emitting diode 6,7,8 are respectively applied for control, display power supply, temperature alarming and low temp compensating and refrigerating chamber are transferred to the switching of refrigerating chamber.
Shown in Figure 2,3,4,5,10 and 4 light emitting diodes 6,7,8,11 of 4 key switches control and display power supply, temperature alarming, low temp compensating and refrigerating chamber is transferred to switching and 4 kinds of duties of quick-frozen of refrigerating chamber respectively are installed on the panel 9 of embodiment 2.12 is the temperature indication and the adjusting knob of compression-type temperature controller.
Fig. 3 is the electrical schematic diagram of embodiment 1 control circuit.The overtemperature signal of pressure temperature controller is by the input of H end. Light emitting diode 6,7,8 is respectively applied for display power supply, temperature alarming and low temp compensating and refrigerating chamber is transferred to the switching of refrigerating chamber.J
1-1Upper and lower end connect pressure temperature controller output and compressor respectively.N connects the 220V zero line, and L connects the 220V live wire.
Fig. 4 is and the connection layout of refrigerator, has very clearly expressed their annexation.
Claims (2)
1, a kind of refrigerator master controller, it by shell, be installed in the control circuit in the shell, gauge tap and the display element that is installed on the shell constituted, it is characterized in that it is the panel type structure, the shell front is installed with panel, gauge tap and display element are installed on the panel, display element is a light emitting diode, gauge tap is a key switch, and key switch and light emitting diode respectively have control respectively and display power supply, temperature alarming and low temp compensating and refrigerating chamber transferred to 3 of switching of refrigerating chamber.
