The application is Application No. 2013106239844, entitled photocatalyst dryer, and the applying date is 2013 12
The divisional application of the application for a patent for invention on the moon 2.
Technical field
The present invention relates to a kind of photocatalyst dryer.
Background technology
Generally, the washing dryer with drying function includes, shell, outer barrel, the roller in outer barrel, for revolving
The motor of tumbler cylinder, for the air circulation duct of air circulation, including blower fan, filter etc..
When the washing dryer with drying function dries clothing, velveteen can be produced in clothing.Velveteen is being washed with hot gas
Wash and circulate together in dryer, and collect in filter.
In traditional washing dryer, filter does not have sterilizing function, causes the bacterium in circulation air can not be complete
It is complete to kill;Filter in use for some time, can become to block, it is necessary to user manually takes out, but washs dryer
User can not be pointed out to take out filter and clear up, cause drying efficiency to decline, or even overheat and cause fire;Or washing
Dryer judges whether filter needs to take out indirectly using air quantity, wind speed measurement, and user is reminded with this.
The content of the invention
Technical problem:Filter without sterilizing function, without blocking prompt facility or can only indirectly judge that filter is
No blocking.
In order to solve the above technical problems, the invention discloses a kind of photocatalyst dryer, concrete technical scheme is 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, the control device of control washing and drying operation is outer for supplying gas to
Heater and fan are installed in the inlet channel of bucket, inlet channel inside, discharge the exhaust passage of gas, connect inlet channel
With the filter of exhaust passage, the filter screen that can be taken off for filtering is installed in filter, filter screen is except ventilation pore
Outside surface coating photocatalyst be used to kill bacterium in circulation air, optical transmitting set is arranged on before filter, is filtered
Device is made of clear material.
Photocatalyst dryer also includes optical receiver, and optical transmitting set and optical receiver are communicated to connect with control device, the two
After being located directly opposite before the filtering means with filter screen respectively, inlet channel and exhaust passage are respectively in upper end one end of filter
It is connected with filter, the light that optical transmitting set sends is via filter, filter screen by optical receiver reception, light emission signal and light
Receive signal and be converted into light transmitting electric signal and light-receiving electric signal, control device calculates light absorbs electric signal/light transmitting telecommunications
Number value, the value be less than threshold value when, control device alarm.
Preferably, filter is made up of transparent strengthened glass.
Preferably, threshold value is set to 0.25, it is also possible to self-defined in the range of 0.1-0.6 by control panel by user.
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,
It is particularly suitable for cleaning children, infantile clothes;Absorb to detect filtering using the transmitting of light, as a result accurately, better than air quantity, wind speed
Etc. Indirect Detecting Method, it is easy to user to use.
Brief description of the drawings
The refer to the attached drawing present invention will become better understood, and the accompanying drawing is only given and is not to the present invention by way of example
Limited, wherein:
Fig. 1 is the profile for illustrating photocatalyst dryer of the invention.
Specific embodiment
Specific reference will be made to Description of Drawings photocatalyst dryer according to a preferred embodiment of the invention now.
With reference to Fig. 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, the inlet channel 6 for supplying gas to outer barrel 2, inlet channel inside is installed by the He of heater 7
Fan 8, discharges the filter 10 of the exhaust passage 9 of gas, connection inlet channel 6 and exhaust passage 9, filter 10
In be provided with for filter the filter screen 11 that can be taken off, filter screen 11 except divulge information pore in addition to surface coating photocatalyst be used for kill
Bacterium in circulation air of going out.Optical transmitting set 12 is arranged on before filter 10, and filter 10 is made of clear material.
Photocatalyst dryer also includes optical receiver 13, optical transmitting set 12 and optical receiver 13 and the communication link of control device 5
Connect, after the two is located directly opposite before the filtering means with filter screen 11 respectively, inlet channel 6 and exhaust passage 9 fill in filtering respectively
The upper end front and back end for putting 10 is connected with filter 10, and the light that optical transmitting set 12 sends is via filter 10, filter screen 11 by light
Receiver 13 absorbs, and light emission signal and light receiving signal are converted into light transmitting electric signal and light-receiving electric signal, control device 5
The value that light absorbs electric signal/light launches electric signal is calculated, when the value is less than threshold value, control device alarm.
Filter 10 is made up of transparent strengthened glass.
Threshold value can be set to 0.25, it is also possible to self-defined in the range of 0.1-0.6 by control panel by user.
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, the heating air of heater 7, fan 8 directs air through inlet channel 6 and introduces a gas into outer barrel 2
In, gas is caught through entering the impurity such as filter 10, line bits by exhaust passage 9 after passing through clothing by filter screen 11.Optical transmitting set
12 send light, through transparent filter 10 to filter screen 11, activate photocatalyst, play bactericidal action.Meanwhile, through filter screen
11 light continues across filter 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 that light absorbs electric signal/light launches electric signal, and the value is less than threshold value
When, control device alarm.
