Description
Technical field
The present invention relates to and the dried object such as clothes, towel is rotated in rotating cylinder while made the clothes drier of its dry this form by hot blast.
Background technology
Structure as existing clothes drier is, such as with reference to Fig. 7, when making motor 31 and 36 action of fuel gas buring unit, drive rotating cylinder 2 to rotate, make the burning and gas-exhausting from fuel gas buring unit 36 be supplied in rotating cylinder 2 from warm-air supply mouth 10 by hot air hose 34 simultaneously.Burning and gas-exhausting in rotating cylinder 2, by the steam vent 21 rotating through inwall 29 of exhaust fan 22, is discharged to outside from blast pipe 20.Thus, the dried object M such as clothes, towel dropped in rotating cylinder 2 is stirred while shower hot blast, makes it in rotating cylinder 2, carry out high temperature drying.After dry operation, in order to make the temperature in rotating cylinder 2 reduce, the cooling implementing to send into cold wind runs.And, be provided with near the door 11 of rotating cylinder 2 for judging the inner temperature of dried object M, the clothes temperature sensor 12 of drying regime.
But this clothes drier, does not put into rotating cylinder 2 by the dried object M that oil content is removed completely in washing, after carrying out high temperature drying, if be placed on for a long time in this condition in rotating cylinder 2, then there is the possibility that nature is on fire by hot blast.This be due to, run even if high temperature drying implements cooling after running and the temperature in rotating cylinder 2 is reduced, also heat can be produced because remaining in the oxidation reaction of the oil content of dried object M, heat suppresses the part in overlap, and cause exceeding the temperature on fire of oil, imflammable gas that the oil content remained in dried object M produces is on fire.Based on this, substantially, the dried object M that attached to oil can not carry out drying in clothes drier.Therefore, in general family, dry cannot attached to the dried object M such as the clothes of the oil of the food materials such as fried oil, fish, and, in hair dressing beautifying shop, beauty salon's (エ ス テ サ ロ Application) etc., even if every day produces the dried object M that attached to solvent, oil content etc. in a large number and can not be dried, such clothes drier is not handy.
So, even if attached to oil content as dried object M also can carry out dry clothes drier, known, in rotating cylinder 2, gas concentration sensor is set, when temperature in rotating cylinder 2 after the technology (Japanese Unexamined Patent Publication 9-56995 publication) of stopping running when above-mentioned gas concentration sensor detects the gas concentration exceeding setting value, rundown exceedes setting value, rotating cylinder 2 rotated and the heat suppressed in dried object M is released, preventing technology (Japanese Unexamined Patent Publication 2-74300 publication) on fire.
Summary of the invention
But, the clothes drier that above-mentioned Japanese Unexamined Patent Publication 9-56995 publication is recorded, cannot detect for during trace when being attached to the oil content on dried object M, excessively reduce detectable concentration to detect it, then the oil content that there will be maloperation or only adhere to minute quantity just can not carry out dry problem to dried object M.
In addition, the clothes drier recorded in Japanese Unexamined Patent Publication 2-74300 publication, owing to causing on fire because of the oxidation of oil in the inside of the dried object M such as stacking clothes, so, when detecting that the temperature in rotating cylinder 2 probably there occurs fire when exceeding setting value in storehouse, can not detect before on fire.And, there is the problem of maloperation the temperature existed when being irradiated to the setting sun in rotating cylinder 2 rises.
The present invention proposes in view of this problem, even if its problem is to provide and a kind of the dried object such as the clothes containing oil content, towel is placed in rotating cylinder for a long time, also reliably can prevent oil content from causing, in rotating cylinder, nature clothes drier on fire occur.
The clothes drier that the present invention relates to, for the hot blast blown by heating devices heat to dried object such as the clothes be housed in cylindric rotating cylinder that front opens is while stir the clothes drier that this dried object makes the form of its drying, wherein,
The assigned position in described rotating cylinder can be communicated to, arrange by through air be at least formed as the oxygen permeation membrane of oxygen enrichment state,
Be provided with make the air in described rotating cylinder by after described oxygen permeation membrane towards the pump that described rotating cylinder is discharged outward,
This clothes drier is configured to, and makes described pump action, the oxygen concentration of the air in described rotating cylinder is reduced to the degree that cannot maintain combustion reaction in described rotating cylinder after dry rundown during the action of clothes drier stops.
According to above-mentioned formation, the air becoming oxygen concentration low air displacement in rotating cylinder is until cannot maintain the degree of combustion reaction.Therefore, after the action of clothes drier stops, even if the dried object of remaining oil content is placed on for a long time also can not be naturally on fire under the state in rotating cylinder.
Also can being that above-mentioned clothes drier is configured to, making when making described pump action described rotating cylinder rotate and again stir inner dried object.
Even if the oxygen concentration in reduction rotating cylinder, also the air of the inside of replacing overlapped dried object is difficult to, so, again stirring dried object by making rotating cylinder rotate, the air of overlapped dried object inside also can be replaced as the low air of oxygen concentration.Therefore, being placed on remaining oil content in the dried object in rotating cylinder after can reliably preventing clothes drier action from stopping further causing nature on fire.
Also can be, in above-mentioned clothes drier, be provided with and contact with the dried object in described rotating cylinder and detect the clothes temperature sensor of its temperature,
Described clothes drier is configured to, and after dry rundown, implements to make described rotating cylinder rotate and again stir the stirring operation of dried object or the cooling that cold wind is sent in described rotating cylinder is run,
To run or after described cooling operation in described stirrings of enforcement, make described pump action when the detected temperatures of described clothes temperature sensor exceedes a reference value based on natural hazard of catch fire temperature.
Thus, run or cooling operation even if implement to stir, also only make pump action when the temperature of dried object exceedes a reference value and make to become hypoxia in rotating cylinder.Pump and oxygen permeation membrane is used when needs just to preventing nature on fire, so, the life-span that can not only extend oxygen permeation membrane and the electric power consumed that can reduce for driving pump.
Above-mentioned clothes drier is preferably, and stops the action of described pump under the state that the oxygen concentration in described rotating cylinder is reduced to 12% ~ 17%.
Can not flame be formed when oxygen concentration in air is less than 17%, so, by oxygen concentration is set in less than 17%, can prevent in rotating cylinder on fire.And the oxygen concentration in air is more than 12% would not cause significant impact to human body.
Another clothes drier that the present invention relates to, for the hot blast blown by heating devices heat to dried object such as the clothes be housed in cylindric rotating cylinder that front opens is while stir the clothes drier that this dried object makes the form of its drying, wherein,
Described heater is gas burner,
This clothes drier is configured to, using the burning and gas-exhausting of the burning of described gas burner generation as warm-air supply in rotating cylinder,
By making described gas burner again burn and be full of burning and gas-exhausting in described rotating cylinder during clothes drier action stops after dry rundown.
Thus, the air displacement in rotating cylinder is become burning and gas-exhausting, make in rotating cylinder, to become the low state of oxygen concentration after the action of clothes drier stops.Therefore, even if dried object also will cause nature on fire because of the oil content remained in dried object under long-time state of placing in rotating cylinder after the action of clothes drier stops.
As mentioned above, according to the clothes drier that the present invention relates to, by reducing the oxygen concentration in rotating cylinder, and making the oil content remained in dried object be difficult to occur oxidation reaction, can prevent in rotating cylinder, nature occurring after clothes drier action stops on fire.Therefore, even if also can not be naturally on fire under the high state of the temperature after clothes drier action stops in rotating cylinder, and, even if also can not breaking out of fire in rotating cylinder when making the temperature in rotating cylinder rise because of the setting sun etc. after clothes drier action stops.Therefore, according to the present invention, the clothes drier that security is high can be provided.
In addition, also can not be naturally on fire under the state that the temperature in rear rotating cylinder is high even if stop in clothes drier action, so the cooling need not implementing to be undertaken by cold wind after dry rundown is run.Therefore, run owing to not implementing cooling, so there will not be cooling to run the unfavorable condition causing condenses moisture in dried object and dried object of getting wet, the dried object of heat can be removed, really carried out drying so can conscientiously experience.

Detailed description of the invention
Illustrate with reference to the accompanying drawings and implement preferred forms of the present invention.
(embodiment 1)
Fig. 1 represents the overall structure of the clothes drier as embodiments of the present invention 1.
Clothes drier shown in Fig. 1, the door 11 of single open-type is rotatably supported on a sidepiece in the front openings portion of casing 1, rotating cylinder 2 is provided with in casing 1, exhaust fan 22, they are carried out to the motor 31 of rotary actuation, embed opening portion before rotating cylinder 2 and the bracing ring 15 that the open end, front 28 of rotating cylinder 2 is supported, be formed in the warm-air supply mouth 10 of the bottom of this bracing ring 15, be used for by hot air hose 34, the burning and gas-exhausting becoming hot blast being supplied to the fuel gas buring unit 36 of warm-air supply mouth 10, be used for the burning and gas-exhausting in rotating cylinder 2 by the blast pipe 20 of exhaust fan 22 to airborne release, with control device 13.
The inwall 29 of rotating cylinder 2 is formed the multiple steam vents 21 be connected with blast pipe 20, and the axle portion 17 outstanding by the center from this inwall 29 rotatably supports rotating cylinder 2.And the open end, front 28 of rotating cylinder 2 is rotatably nested in the periphery of the bracing ring 15 be fixed on casing 1.
Rotating cylinder 2 is connected with power delivery status with motor 31 respectively by first, second driving belt 32,33 with exhaust fan 22, by the driving of motor 31, makes rotating cylinder 2 and exhaust fan 22 rotate respectively.
Be provided with in the fixed position, bottom of bracing ring 15 and contact and the clothes temperature sensor 12 of its temperature of perception with dried object M such as the clothes in rotating cylinder 2, in assigned position, top, by suction pump 30 make through the air oxygen permeation membrane 3 that at least becomes oxygen enrichment state be arranged to the inside and outside state be communicated with.
At this, oxygen permeation membrane 3 comprise the oxygen only only transmitted in air oxygen permeation membrane, make oxygen in air than nitrogen through more oxygen permeation membrane etc.As this oxygen permeation membrane 3, such as can use by the gas separation membrane of the oxygen in air and nitrogen separation or when through usual air (oxygen is about 21%, nitrogen be about 79% air) time become the oxygen concentration oxygen enrichment air higher than this usual air (oxygen is about 30%, nitrogen be about 70% air) oxygen enrichment film etc.When the gas separation membrane of oxygen and nitrogen separation is used as oxygen permeation membrane 3, as long as rotating cylinder 2 is arranged to make nitrogen gas component turn back in rotating cylinder 2, make oxygen gas component discharge outside rotating cylinder 2.
When the dried object M clothes driers such as clothes are carried out drying, dried object M is accommodated in rotating cylinder 2, operation run switch (not shown), drives fuel gas buring unit 36 and motor 31 and carry out drying operation.So the gas burner 37 of fuel gas buring unit 36 burns, and first, second driving belt 32,33 that is rotated through of motor 31 is delivered to rotating cylinder 2 and exhaust fan 22, and rotating cylinder 2 and exhaust fan 22 rotate.From the burning and gas-exhausting of gas burner 37, as shown in the white arrow of Fig. 1, in rotating cylinder 2, supply hot blast from warm-air supply mouth 10 by hot air hose 34.Be supplied to above-mentioned burning and gas-exhausting in rotating cylinder 2 by after steam vent 21 from hot air hose 34, be discharged to air from blast pipe 20.Thus, the dried object M be put in rotating cylinder 2 is stirred while be subject to the burning and gas-exhausting of the high temperature from gas burner 37 in the rotating cylinder 2 rotated, thus dried gradually.
After dry rundown, make gas burner 37 not carry out burning and driving exhaust fan 22, the cooling implementing flowing cold wind in rotating cylinder 2 thus runs.Thus, the temperature in storehouse is made to decline.Now, also carrying out by making rotating cylinder 2 rotating and again stirring dried object M, opening wide by the heat suppressed in the dried object M that overlap.
During cooling rundown, detect the temperature of dried object M with clothes temperature sensor 12.Now, if the detected temperatures Y of clothes temperature sensor 12 at a reference value t DEG C (such as 20 DEG C) based on dangerous temperature naturally on fire below, then dried object M is placed in rotating cylinder 2 also passable in this condition.But the temperature Y that temperature sensor 12 of pledging clothes detects is when exceeding a reference value t DEG C, may there is oxidation reaction in the oil content be attached on dried object M, on fire because of the heat had in dried object M.Said reference value t DEG C can set arbitrarily according to the natural hazard of catch fire temperature corresponding with the kind of the remaining oil content be attached on dried object M.
When the detected temperatures Y of clothes temperature sensor 12 exceedes a reference value t DEG C, make suction pump 30 action and carry out deoxygenation operation.Now, by exhaust fan 22 is placed in OFF state, the air in rotating cylinder 2 can not initiatively move towards blast pipe 20 effluent, but as shown in the black arrow of Fig. 1, flows to suction pump 30 side, by oxygen permeation membrane 3, thus the oxygen in rotating cylinder 2 is discharged towards the outside.Like this, by being attracted the air in rotating cylinder 2 by suction pump 30, and the oxygen concentration of the air in rotating cylinder 2 is reduced gradually.
Due to really can not fire be formed when oxygen concentration is below 17%, so, make suction pump 30 action be used for making the oxygen concentration in rotating cylinder 2 become the deoxygenation time (such as, carrying out a hours) of the regulation of 12% ~ 17%.The deoxygenation time is different because of the size, kind etc. of the volume in rotating cylinder 2, oxygen permeation membrane 3, the traffic attraction of suction pump 30 etc., also can be decided by test etc.
In addition, in above-mentioned deoxygenation running, make rotating cylinder 2 rotate once above, stirring dried object M, just the air suppressed in the intersection of dried object M also can be replaced as hypoxic air.Thus, even if attached to the occasion of oil content on dried object M, also can reliably prevent in rotating cylinder 2 on fire.
The microcomputer of the control program of content shown in the flow chart having Fig. 2 is assembled in control device 13.Below, the action of the clothes drier related to by the process description present embodiment 1 of Fig. 2.
When pressing is disposed in run switch (not shown) in the front of casing 1, with reference to Fig. 2, in step S1, by the driving of motor 31, exhaust fan 22 and rotating cylinder 2 are rotated, make the gas burner 37 of fuel gas buring unit 36 burn simultaneously and start to carry out drying operation.In step S2, run until carry out drying through the drying time of the regulation needed for super-dry, after drying time, judge dry rundown in step S3 and gas burner 37 is put out a fire.Drying time can set by corresponding drying mode automatically, also can be set arbitrarily by configuration switch drying time (not shown).
In step S4 thereafter, carry out cooling and run until pass through the cool time of regulation.Cooling operates to, and makes gas burner 37 put out a fire in step s3, but the rotation of exhaust fan 22 and rotating cylinder 2 is also in continuation, so cold wind is delivered in rotating cylinder 2 from outside by hot air hose 34.And, in step s 4 which after cool time, make the rotation of exhaust fan 22 and rotating cylinder 2 stop in step s 5, and the cooling that ends run.Cool time can set corresponding above-mentioned drying time automatically, also can be set arbitrarily by configuration switch cool time (not shown).
Then, in step s 6, during cooling rundown, being detected the temperature of dried object M by clothes temperature sensor 12, making when judging that detected temperatures Y is below a reference value t DEG C whole actions of this clothes drier end.
On the other hand, in step s 6, when the detected temperatures Y of temperature sensor 12 of pledging clothes exceedes a reference value t DEG C, suction pump 30 action is made in the step s 7, and, make rotating cylinder 2 again rotate and carry out deoxygenation operation.Carrying out deoxygenation operation in step s 8, until have passed through the regulation deoxygenation time making the oxygen concentration in rotating cylinder 2 become 12% ~ 17%, when have passed through after the deoxygenation time, making suction pump 30 and rotating cylinder 2 stop in step s 9.Thus whole actions of this clothes drier are ended.
Below, the relation of the temperature based on the oxygen concentration in the operating rotating cylinder 2 of above-mentioned control program and dried object M is described by the relevant icon of Fig. 3.
As shown in the correlation graph of Fig. 3, dropping into the occasion of the dried object M of standard volume in rotating cylinder 2, in the drying making gas burner 37 burn runs, a large amount of burning and gas-exhausting flows in rotating cylinder 2, so, as shown in the X curve in chart, the rapid decline of oxygen concentration.And the major part from the heat of the burning and gas-exhausting of gas burner 37 is absorbed by dried object M, so the upstroke slope of the temperature of the dried object M that clothes temperature sensor 12 detects becomes large as shown in the Y curve in chart.
When forwarding cooling operation to when dry rundown, in step S3, the burning of gas burner 37 is stopped, burning and gas-exhausting does not flow in rotating cylinder 2, so the oxygen concentration X in rotating cylinder 2 gets back to nature, meanwhile, the temperature Y of dried object M reduces gradually.After cooling rundown, suction pump 30 is placed in ON and carries out deoxygenation operation, thus, by the oxygen in rotating cylinder 2 is discharged towards the outside from oxygen permeation membrane 3, thus the oxygen concentration X in rapid reduction rotating cylinder 2.Under state oxygen concentration X being reduced to can not to form fire in rotating cylinder 2 less than 17%, suction pump 30 is placed in OFF, makes deoxygenation rundown, stop the action of clothes drier.
Run by above deoxygenation, make the oxygen concentration in rotating cylinder 2 be reduced to less than 17%, thus, make the oil content remained on dried object M be difficult to oxidation reaction occurs, can prevent that after the action of clothes drier stops nature occurring in rotating cylinder 2 on fire.Therefore, though the action of clothes drier stop after temperature height in rotating cylinder 2 also nature can not to occur on fire, and, even if also can not breaking out of fire in rotating cylinder 2 when clothes drier action causes the temperature in rotating cylinder 2 to rise because of the setting sun etc. after stopping.And, because oxygen concentration remains on more than 12%, even if so immediately door 11 is opened after suction pump 30 is placed in OFF and also can not cause significant impact to human body.Therefore, the clothes drier that security can be provided high.
In addition, even if place under the state of clothes drier action stopping, outer gas also can not initiatively be admitted in rotating cylinder 2, so the oxygen concentration in rotating cylinder 2 can maintain low state, but just recovers nature gradually after some times.Under this occasion, when the oxygen concentration in rotating cylinder 2 returns to the concentration that can form flame time, the temperature of dried object M has been reduced to impossible generation temperature naturally on fire, so, even if dried object M attached to oil content also can not be on fire in rotating cylinder 2.
In addition, preferably in 1, in step s 6, only make suction pump 30 action when the detected temperatures Y of clothes temperature sensor 12 is judged as and exceedes a reference value t DEG C, make oxygen in rotating cylinder 2 by oxygen permeation membrane 3 towards the outside through, so, suction pump 30 can be reduced and drive the electric power consumed, and the life-span of oxygen permeation membrane 3 can be extended.
In above-mentioned embodiment 1, suction pump 30 is arranged on than oxygen permeation membrane 3 more by rotating cylinder 2 side, be configured to the air be attracted after pump 30 attracts is discharged by oxygen permeation membrane 3, but, also can be as shown in Figure 4, instead, oxygen permeation membrane 3 is disposed on bracing ring 15, and suction pump 30 is arranged on the outside of oxygen permeation membrane 3.In this occasion, the air in rotating cylinder 2 by oxygen permeation membrane 3, was discharged to outside in this condition before being attracted pump 30 attraction.
And above-mentioned embodiment 1, heater also can replace gas burner 37, and is implemented as the clothes drier of the electric using the electric heaters such as heater.This occasion, burning and gas-exhausting can not be admitted in rotating cylinder 2, so in dry operation, as shown in the X curve of Fig. 3, oxygen concentration can not reduce, and the air in rotating cylinder 2 is all nature until making oxygen till with pump action.
(embodiment 2)
In embodiment 1, have employed oxygen permeation membrane 3 and suction pump 30 to make the oxygen concentration in rotating cylinder 2 reduce, but in embodiment 2, do not adopt these oxygen permeation membranes 3 and suction pump 30, and the oxygen concentration in rotating cylinder 2 is reduced.
Fig. 5 is the flow chart of run action of the clothes drier representing this embodiment 2, and Fig. 6 is the correlation diagram of the temperature of oxygen concentration in above-mentioned operating rotating cylinder 2 and dried object M.Run action shown in the flow chart of Fig. 5 is realized by control device 13.
In embodiment 2, in flowchart process shown in Fig. 5, identical to step S6 from the step S1 of the control of the embodiment 1 shown in step S11 to step S16 and Fig. 2, under the detected temperatures Y of clothes temperature sensor 12 exceedes the occasion of a reference value t DEG C in step s 16, while in step S17, gas burner 37 is lighted a fire again, the deoxygenation implementing rotating cylinder 2 is rotated again runs.Now, exhaust fan 22 is made to carry out more weak rotation.At this, when the rotating speed of the more weak rotation of exhaust fan 22 is dry operation exhaust fan 22 rotating speed about 10% ~ 50%.By making gas burner 37 burn, burning and gas-exhausting invades in rotating cylinder 2, and the air in rotating cylinder 2 is pushed out from blast pipe 20 by the exhaust fan 22 being in more weak rotation status.By exhaust fan 22 is maintained in more weak rotation status, thus during the deoxygenation time, in rotating cylinder 2, be full of burning and gas-exhausting in step S18.
Thus, burning and gas-exhausting is sent in rotating cylinder 2, thus, with reference to the correlation diagram of Fig. 5, after cooling rundown, oxygen concentration rapid reduction as shown in X curve of the air in rotating cylinder 2, meanwhile, the temperature of dried object M rises slightly as shown in Y curve.And, through the deoxygenation time of regulation, oxygen concentration in the rotating cylinder 2 being filled with burning and gas-exhausting become can not cause more than 12% of significant impact to human body and for can not form flame less than 17% when, in step S19, make the rotation of exhaust fan 22 and rotating cylinder 2 stop, and gas burner 37 is put out a fire, stop the action of clothes drier.
In such embodiment 2, also in the same manner as embodiment 1, run by above-mentioned deoxygenation, make the oxygen concentration in rotating cylinder 2 reduce and make the oil content remained on dried object M be difficult to cause oxidation reaction, can prevent in rotating cylinder 2 naturally on fire after clothes drier action stops.Therefore, the clothes drier that security can be provided high.
And then, in the clothes drier of embodiment 2, in order to make the oxygen concentration in rotating cylinder 2 reduce, do not need to arrange oxygen permeation membrane 3 and suction pump 30, so may be provided in this low clothes drier.
(other embodiment)
In the respective embodiments described above 1,2, in the control program shown in Fig. 2 and Fig. 5, carry after the cooling of step S4, S14 runs, the step S6 of the temperature of dried object M, S16 is detected with clothes temperature sensor 12, but, the non-essential setting of this step S6, S16, also can cooling rundown after, with the oxygen concentration that temperature independently carries out step S7, the deoxygenation of S17 runs and reduces in rotating cylinder 2 of dried object M.
And then, reliably can reduce the oxygen concentration in rotating cylinder 2 in the step S7 shown in Fig. 2 and Fig. 5, S17, therefore, even if also do not worry oil content oxidation reaction and cause on fire under the state that the temperature of dried object M is higher.Therefore, the enforcement that the cooling in the step S4 shown in Fig. 2 and Fig. 5, S14 runs can also be omitted.After drying runs, do not carry out cooling run, would not occur because making the unfavorable condition of being got wet by the dried object M shower cold wind of high temperature drying, can take out from rotating cylinder 2 warm for dried object M after dry rundown, be easy to the drying experiencing dried object M.
And then the present invention also can be implemented as the functions/drying device of scrubbing-and-drying unit.
