Description
Technical field the present invention relates to the air cleaning unit in a kind of household appliance technical field.
The purification of air machine is used for room air is carried out filtration, purification, can be divided into desk-top and wall-hanging, and wall-hanging is installed on the wall, carries out straighforward operation with remote controller.Some desk-top clearing machines also with detection and the display circuit of air quality, show by air borne sensor detection air quality and by the LCD LCDs, reach the purpose that supplies the user in time to understand air quality and carry out corresponding operating.But the air cleaner (comprising the inappropriate table air cleaning machine in some installation sites) for wall-hanging, because main frame is hung on the wall, even with Detection of Air Quality and display circuit, obviously also inconvenient user watches, if and want Detection of Air Quality and display circuit are arranged on the remote controller, because air borne sensor needs larger operating current, the battery of remote controller can't be for air borne sensor normally, and prior art does not address this problem always.
Summary of the invention purpose of the present invention is the air cleaner that open a kind of like this user of convenience understands ambient air quality, and it can detect and show air quality, and allows the user observe more easily.
The present invention includes main frame and the remote controller of air cleaner, it is characterized in that: be provided with air borne sensor, detection and coding circuit and radiating circuit at main frame, the output of air borne sensor is connected to the input that detects with coding circuit, detect with the signal of coding circuit to air borne sensor and detect and the signal processing, and through launching by radio-frequency transmissions circuit or infrared transmitting circuit behind the coding; Be provided with supporting receiving circuit, decoding and drive circuit and display circuit at remote controller, receiving circuit is used for the signal of Receiving Host emission, its output is connected to decoding and drive circuit, by decoding to received signal and after display driver processes, its output is connected to display circuit, shows by LED or LCD display.
The present invention is simple and practical, the air borne sensor that power consumption is larger in air detection and the display circuit is arranged on the main frame, guaranteed the normal operation of air borne sensor by the power supply of main frame, and the display part that power consumption is small is arranged on the remote controller, both carry out signal by wireless transmission and receiving circuit and transmit, the user need not walk close to main frame, just can observe easily the demonstration of detected air quality on remote controller.
As improvement, also be provided with reception and emission linkage control circuit on the remote controller.This circuit makes receiving circuit and remote-transmitter interlock, only when remote controller carries out straighforward operation (when the button of pressing remote controller is arranged), just start the work of receiving circuit, and when not having straighforward operation, through the work of autoshutdown receiving circuit after the time-delay of certain hour.Reach the effect of saving power supply, be more suitable in the characteristics of remote controller baby battery power supply.
As another improvement, be provided with emission and receive linkage control circuit at main frame.This circuit makes radiating circuit and remote-control receiving circuit interlock, only after main frame receives the remote signal of remote controller emission and makes corresponding operation, just starts the work of radiating circuit, and close the work of radiating circuit after finishing emission work.This improvement reaches power saving and prolongs the effect in transmitting tube life-span, and can effectively avoid interfering with each other between the transmitting and receiving circuit of main frame, makes work more reliable and more stable.
Description of drawings Fig. 1 is the circuit theory diagrams of the host machine part of the embodiment of the invention.
Fig. 2 is the circuit theory diagrams of the remote controller part of the embodiment of the invention.
The present invention will be described according to accompanying drawing below the specific embodiment.
In the host machine part of Fig. 1, realize detection of the present invention and coding circuit, with remote control reception and the shared Micro-processor MCV 1 of control function treatment circuit of original host, model is PIC16C712.In order to simplify, the circuit of original technology part of main frame does not draw.KQ1 is an air mass sensor, here adopt model QS-01 commonly used, the output voltage of its 2nd pin changes along with the pollution level of air, the 2nd pin is connected to the input I/O1 with mould/number conversion function of MCU1, ADC functional module by the MCU1 the inside is carried out the A/D conversion to voltage signal, obtain the digitized signal corresponding with air quality, then by the program of MCU1 this digitized signal is encoded, deliver to the radiating circuit that is formed by Q1 and HD1 by I/O2 output again, launch by infrared emission tube HD1 after being amplified by triode Q1.
In Fig. 2 remote controller part, realize decoding of the present invention and drive circuit, share a Micro-processor MCV 2 with the original remote controlled transmitting circuit of remote controller, model also is PIC16C712, in order to simplify, the circuit of the parts such as the keyboard input of the original technology of remote controller does not draw.Three end infrared receiver module HW2 (model C HQ1838) are as receiving circuit, its output is connected to the input I/O1 of MCU2, MCU2 reads the reception signal, decode to received signal by program, solve the voltage signal corresponding with air quality, through after conversion and the display driver processing, be connected on the LCDs LCD by one group of I/O output pin again, demonstrate the detected air pollution degree of main frame air borne sensor, reach purpose of the present invention.
As improvement, in the remote controller of Fig. 2, triode Q2 and MCU2 output pin I/O2 etc. consist of " receiving and the emission linkage control circuit ", be used for the power supply of control receiving circuit HW2, at ordinary times I/O2 output high level, the Q2 cut-off, HW2 does not work, be that the user is when pressing the button of remote controller when remote controller operates, the I/O2 output low level of MCU2, the Q2 conducting starts the work of HW2 to receive signal, work through autoshutdown HW2 after the time-delay of certain hour (such as about 1 second) reaches the effect of saving energy.
In the main frame of Fig. 1, the MCU1 of main frame also takes into account the function of realization " emission and reception linkage control circuit " simultaneously.This circuit makes radiating circuit and remote-control receiving circuit interlock by program, the I/O2 of MCU1 does not export and transmits at ordinary times, only receive the remote signal of remote controller emission by HW1 at MCU1, and after making corresponding straighforward operation, the signal corresponding to air quality that just air borne sensor is detected, by I/O2 output, start the work of radiating circuit Q1 and HD1, and after finishing emission work, again close the work of radiating circuit Q1 and HD1.
The present embodiment adopts infrared emitting and reception to finish signal of the present invention and transmits and receives circuit, and practical application also can be adopted the radio frequency transmit and receive circuit, is the same for its principle of the present invention.
Disclosed in this invention, that the air mass signal that main frame detects is shown by being wirelessly transmitted on the remote controller and by LCDs, can also be with other job informations of main frame in the actual product, function such as air quantity, sterilization, purification etc. is selected information, be transmitted on the remote controller and show more convenient user's use.
Realize program of the present invention as for the Micro-processor MCV the inside, this belongs to the ordinary skill of this technical field, the professional and technical personnel in this field, and content disclosed according to the present invention just can realize its function by coding, does not do being described in detail here.
