Photocatalyst dryer
Technical field
The present invention relates to a kind of photocatalyst 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 a kind of photocatalyst dryer, concrete technical scheme are as follows.
The present invention provides a kind of photocatalyst dryer different from conventional art means, including:Housing, arrangement is in the housing
For the roller of accommodating laundry, the door of clothes is picked and placeed, controls the control device of washing and drying operation, it is outer for supplying gas to
The inlet channel of bucket, inlet channel inside installation heater and fan, discharge the exhaust passage of gas, connect inlet channel
With the filtration apparatus of exhaust passage, the strainer that can be taken off for filtering is installed, strainer is except pore of divulging information in filtration apparatus
Outside surface coating photocatalyst be used to kill bacterium in circulation air, optical transmitting set is arranged on before filtration apparatus, is filtered
Device is made of clear material.
Photocatalyst dryer further includes optical receiver, optical transmitting set and optical receiver and is communicated to connect with control device, the two
After being located directly opposite before the filtering means with strainer respectively, inlet channel and exhaust passage are respectively in upper end one end of filtration apparatus
It is connected with filtration apparatus, the light that optical transmitting set is sent is received via filtration apparatus, strainer by optical receiver, light emission signal and light
Receive signal and be converted into light emitting electric signal and light-receiving electric signal, control device calculates light absorbs electric signal/light emitting telecommunications
Number 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 photocatalyst dryer according to the present invention.
Embodiment
It specific reference will be made to the photocatalyst dryer of attached drawing description according to a preferred embodiment of the invention now.
With reference to figure 1, photocatalyst dryer includes, housing 1, and arrangement is used for the roller 3 of accommodating laundry in the housing, picks and places clothing
The door 4 of clothes, control device 5, for supplying gas to the inlet channel 6 of outer barrel 2,7 He of heater is installed inside inlet channel
Fan 8, discharges the exhaust passage 9 of gas, connects the filtration apparatus 10 of inlet channel 6 and exhaust passage 9, filtration apparatus 10
In the strainer 11 that can be taken off for filtering is installed, surface coating photocatalyst of the strainer 11 in addition to pore of divulging information is used to kill
Bacterium in circulation air of going out.Optical transmitting set 12 is arranged on before filtration apparatus 10, and filtration apparatus 10 is made of clear material.
Photocatalyst dryer further includes optical receiver 13, optical transmitting set 12 and optical receiver 13 and 5 communication link of control device
Connect, after the two is located directly opposite before the filtering means with strainer 11 respectively, inlet channel 6 and exhaust passage 9 are filled in filtering respectively
Put 10 upper end front and back end to be connected with filtration apparatus 10, the light that optical transmitting set 12 is sent is via filtration apparatus 10, strainer 11 by light
Receiver 13 absorbs, and light emission signal and light receiving signal are converted into light emitting electric signal and light-receiving electric signal, control device 5
The value of light absorbs electric signal/light emitting electric signal is calculated, 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.
