Abstract
The utility model relates to a kind of dust alarm structures of domestic air conditioning.It includes indoor host computer, indoor host computer is equipped with circuit board and return air inlet, filter screen is equipped at return air inlet, infrared transmitting tube and infrared receiving tube are located at the inner side and outer side of filter screen, and filter screen is between infrared transmitting tube and infrared receiving tube, when the dust of filter screen reaches certain thickness, when infrared receiving tube can not receive the optical signal of infrared transmitting tube, circuit board sends alarm signal to warning circuit, and warning circuit sounds an alarm, to remind user to clean filter screen in time.The utility model is by being respectively set infrared receiving tube and infrared transmitting tube inside and outside the filter screen of the return air inlet of domestic air conditioning, and using infrared signal come the dust thickness on real-time detection filter screen, when the thickness of filter screen reaches a certain level, the utility model can sound an alarm, to remind user to clean filter screen in time.
Description
Technical field
The utility model relates to domestic air conditioning technical field, the dust alarm structure of especially a kind of domestic air conditioning.
Background technique
With the continuous extension of infrared signal transmission application field, the market demand is growing, while household electric appliances are also opened
The infrared science and technology of application that begins realizes the prompt of security risk.Household electrical appliances safety operation is carried out with infrared tube, is that modern household electrical appliances are a kind of
One of advanced infrared technique.General domestic air conditioning only realizes remote control output optical signal, is converted by receiving optical signal
Electric signal is to realize air-conditioning normal operation.
Common sky wither use or unused strainer can still accumulate dust, if not in time cleaning will affect air-conditioning
Using and function.Even if being such case occur, people may not necessarily also have found in time, but then continue to using air-conditioning, from
And substantially reduce the reliability used product.
Utility model content
The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide that a kind of structure is simple, closes
The dust for the domestic air conditioning managed, the dust thickness on real-time detection filter screen, and user is reminded to clean filter screen in time, which is alarmed, to be tied
Structure.
Purpose of the utility model is realized as follows:
A kind of dust alarm structure of domestic air conditioning, including indoor host computer, indoor host computer are equipped with circuit board and return air inlet,
Filter screen is equipped at the return air inlet, the circuit board is equipped with infrared receiving circuit, infrared transmitting circuit and warning circuit,
Infrared receiving circuit is equipped with infrared receiving tube, and infrared transmitting circuit is equipped with infrared transmitting tube, characterized in that the infrared hair
Penetrate pipe and infrared receiving tube be located at the inner side and outer side of filter screen, filter screen be located at infrared transmitting tube and infrared receiving tube it
Between, the infrared transmitting tube and infrared receiving tube are in same horizontal line, infrared when the dust of filter screen reaches certain thickness
When reception pipe can not receive the optical signal of infrared transmitting tube, circuit board sends alarm signal to warning circuit, warning circuit hair
Alarm out, to remind user to clean filter screen in time.
The beneficial effects of the utility model are as follows:
(1) the utility model inside and outside the filter screen of the return air inlet of domestic air conditioning by being respectively set infrared connect
Closed tube and infrared transmitting tube, and using infrared signal come the dust thickness on real-time detection filter screen, when the thickness of filter screen
When reaching a certain level, the utility model can be sounded an alarm, to remind the ash of the domestic air conditioning of user's cleaning filter screen in time
Dirt alarm structure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the dust alarm structure of the utility model domestic air conditioning.
Fig. 2 is the circuit diagram of the utility model domestic air conditioning.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
As shown in Fig. 1 to Fig. 2, a kind of dust alarm structure of domestic air conditioning, including indoor host computer 1 is set on indoor host computer 1
There are circuit board and return air inlet 11, filter screen 13 is equipped at the return air inlet 11, the circuit board 14 is equipped with infrared receiving circuit
15, infrared transmitting circuit 16 and warning circuit 17, infrared receiving circuit 15 are equipped with infrared receiving tube 151, infrared emission electricity
Road 16 is equipped with infrared transmitting tube 152, and the infrared transmitting tube 152 and infrared receiving tube 151 are located at the interior of filter screen 13
Side and outside, filter screen 13 is between infrared transmitting tube 152 and infrared receiving tube 151, the infrared transmitting tube 152 and infrared
Reception pipe 151 is in same horizontal line, and when the dust of filter screen 13 reaches certain thickness, infrared receiving tube 151 can not be received
To infrared transmitting tube 152 optical signal when, circuit board 14 sends alarm signal to warning circuit 17, and warning circuit 17 issues police
Report, to remind user to clean filter screen 13 in time.
Working principle of the utility model is:
The utility model is by being respectively set infrared connect inside and outside the filter screen 13 of the return air inlet 11 of domestic air conditioning
Closed tube 151 and infrared transmitting tube 152, and work as filtering using infrared signal come the dust thickness on real-time detection filter screen 13
When the thickness of net 13 reaches a certain level, circuit board 14 sends alarm signal to warning circuit 17, and warning circuit 17 can issue police
Report, to remind the dust alarm structure of the domestic air conditioning of user's cleaning filter screen 13 in time.
