One kind washing dryer
Technical field
The present invention relates to one kind to wash dryer.
Background technology
In general, the washing dryer with drying function includes, and shell, outer barrel, the roller in outer barrel, for revolving
The driving motor of tumbler cylinder, for the air circulation duct of air circulation, including wind turbine, filtration apparatus etc..
When the washing dryer with drying function dries clothing, velveteen can be produced in clothing.Velveteen is being washed with hot gas
Wash in dryer and circulate together, and collect in filtration apparatus.
In traditional washing dryer, filtration apparatus does not have sterilizing function, causes the bacterium in circulation air cannot be complete
It is complete to kill;Filtration apparatus in use for some time, can become to block, it is necessary to which user manually takes out, but washs dryer
User cannot be prompted to take out filtration apparatus and cleared up, cause drying efficiency to decline, or even overheat and cause fire;Or washing
Dryer judges whether filtration apparatus needs to take out indirectly using air quantity, wind speed measurement, and user is reminded with this.
The content of the invention
Technical problem:Filtration apparatus is no to block prompt facility or judge that filtration apparatus is indirectly without sterilizing function
No blocking.
In order to solve the above technical problems, the invention discloses one kind to wash dryer, concrete technical scheme is as follows.
The present invention provides a kind of washing dryer different from conventional art means, including:Housing, outer barrel, is arranged in outer
It is used for the roller of accommodating laundry in bucket, picks and places the door of clothes, the control device of control washing and drying operation, for gas to be supplied
To the inlet channel of outer barrel, heater and fan are installed inside inlet channel, discharge the exhaust passage of gas, connects air inlet
The filtration apparatus of passage and exhaust passage, the strainer that can be taken off for filtering is provided with filtration apparatus, strainer is except ventilation
Surface coating photocatalyst outside pore is used to kill the bacterium in circulation air, and optical transmitting set is arranged on before filtration apparatus,
Filtration apparatus is made of clear material.
Washing dryer further includes optical receiver, optical transmitting set and optical receiver and is communicated to connect with control device, the two point
After not being located directly opposite before the filtering means with strainer, inlet channel and exhaust passage respectively upper end one end of filtration apparatus with
Filtration apparatus connects, and the light that optical transmitting set is sent is received via filtration apparatus, strainer by optical receiver, and light emission signal and light connect
The collection of letters number is converted into light emitting electric signal and light-receiving electric signal, and control device calculates light absorbs electric signal/light emitting electric signal
Value, when which is less than threshold value, control device alarm.
Preferably, filtration apparatus is made of transparent strengthened glass.
Preferably, threshold value is set to 0.25, can also by user by control panel in the range of 0.1-0.6 it is self-defined.
Preferably, control device is alarmed by acousto-optic devices such as buzzer/displays.
Preferably, optical transmitting set and optical receiver are fixed on shell bottom plate or side plate by fixing device such as screw, card
In order to demolition and maintenance.
Beneficial effect of the present invention:Using the present invention, sterilization processing can be carried out to circulation air, it is ensured that the cleaning of clothing,
Particularly suitable for cleaning children, infantile clothes;Absorbed using the transmitting of light to detect filtering, as a result accurately, better than air quantity, wind speed
Etc. Indirect Detecting Method, used easy to user.
Brief description of the drawings
The refer to the attached drawing present invention will become better understood, and the attached drawing is given only in an example and is not to the present invention
Limited, wherein:
Fig. 1 is the profile for illustrating washing dryer according to the present invention.
Embodiment
It specific reference will be made to the washing dryer of attached drawing description according to a preferred embodiment of the invention now.
With reference to figure 1, washing dryer includes, housing 1, outer barrel 2, is arranged in the roller 3 for being used for accommodating laundry in outer barrel 2,
The door 4 of clothes is picked and placeed, control device 5, for supplying gas to the inlet channel 6 of outer barrel 2, heating is installed inside inlet channel
Device 7 and fan 8, discharge the exhaust passage 9 of gas, connect the filtration apparatus 10 of inlet channel 6 and exhaust passage 9, filtering
The strainer 11 that can be taken off for filtering, surface coating photocatalyst of the strainer 11 in addition to pore of divulging information are installed in device 10
For killing the bacterium in circulation air.Optical transmitting set 12 is arranged on before filtration apparatus 10, and filtration apparatus 10 is by transparent material
It is made.
Washing dryer further includes optical receiver 13, optical transmitting set 12 and optical receiver 13 and is communicated to connect with control device 5,
After the two is located directly opposite before the filtering means with strainer 11 respectively, inlet channel 6 and exhaust passage 9 are respectively in filtration apparatus 10
Upper end front and back end be connected with filtration apparatus 10, the light that optical transmitting set 12 is sent is via filtration apparatus 10, strainer 11 by light-receiving
Device 13 absorbs, and light emission signal and light receiving signal are converted into light emitting electric signal and light-receiving electric signal, and control device 5 calculates
The value of light absorbs electric signal/light emitting electric signal, when which is less than threshold value, control device alarm.
Filtration apparatus 10 is made of transparent strengthened glass.
Threshold value can be set to 0.25, can also by user by control panel in the range of 0.1-0.6 it is self-defined.
Control device is alarmed by acousto-optic devices such as buzzer/displays.
Optical transmitting set 12 and optical receiver 13 can be fixed on shell bottom plate or side plate by fixing device such as screw, card
In order to demolition and maintenance.
During drying operation, heater 7 heats air, and fan 8 directs air through inlet channel 6 and introduces a gas into outer barrel 2
In, gas is passed through by exhaust passage 9 into filtration apparatus 10 after passing through clothing, and the impurity such as line is considered to be worth doing are caught by strainer 11.Optical transmitting set
12 send light, through transparent filtration apparatus 10 to strainer 11, activate photocatalyst, play bactericidal effect.Meanwhile through strainer
11 light continues across filtration apparatus 10, is received by optical receiver 13, and transmitting optical signal and reception optical signal are converted to electricity
Control device 5 is transferred to after signal, control device 5 calculates the value of light absorbs electric signal/light emitting electric signal, which is less than threshold value
When, control device alarm.
