[patent documentation 2] TOHKEMY 2000-271399 communique
But, in existing clothes drying device, be easy to generate the problem of the uneven drying of M such as clothing.
More at large describe with regard to the problems referred to above point below.
In above-mentioned existing apparatus, at the beginning initial stage of dry operating, heater 31 is with the 8th grade of heating of the highest heating grade, after this, when the clothing temperature that is detected as clothing temperature sensor S1 rises to the clothing critical temperature, or the delivery temperature that is detected as exhaust gas temperature sensor S2 is when rising to the exhaust critical temperature, for preventing to heat the harmful effect that brings to M such as clothings, the caloric value of heater 31 is adjusted downward to the 7th grade.In addition, even above-mentioned clothing temperature etc. have still surpassed under the situation with above-mentioned clothing critical temperature with sample value etc. with the 7th grade of heating at heater 31, reduce 6 grades → the 5th grade of the heating flow control of heater 31 further step by step ..., heat to harmful effects that M was brought such as clothings preventing.

[unitary construction]
The mechanical realization of clothes drying device and described Fig. 3, content shown in Figure 4 are identical, thus following recorded and narrated with the explanation of described prior art different content.
As shown in Figure 4, shell 1 is a rectangular shape, and having with articulated section 17 in its former configuration simultaneously is the single open-door formula switch door 13 that fulcrum rotates folding.In addition, on this switch door 13, be provided with handle 19.
As shown in Figure 3, on the warm-air supply mouth 30 of the bottom that is opened in support ring 3, be connected with the upper end open of hot gas duct 32.But these support ring 3 free rotaring ground supportings are contained in the front end of the cylinder 10 in the shell 1.This hot gas duct 32 is used to guide the burning of gas burner 31a to discharge gas.In addition, on support ring 3, dispose clothing temperature sensor S1 and electrode sensor S3.This clothing temperature sensor contacts with M such as clothing when carrying out drying process, thereby detects the clothing temperature.This electrode sensor is used for judging its degree of drying with after M such as clothing contact.Whether, by electrode sensor S3 when clothing etc. contact be "on" position, thereby the detection drying whether if as shown in Figure 5, crossing at M such as clothings under the state of two electrode K1, K2 that electrode sensor exposes.Specifically, under the low situation of humidity height, its resistance of M such as clothing, M such as clothing are as conductor conduction electrode K1, K2; And under the high situation of M dryings such as clothing, its resistance,, can not make its conducting though M such as clothing contact with electrode K1, K2.Therefore, in dry operating, the frequency that contacts and then be switched on according to electrode K1, K2 and M such as clothing, thus the drying of judging M such as this clothing is whether.
In addition, periphery is erected with endless belt 16 in the rear end of cylinder 10, and this endless belt 16 is driven by the gyroaxis 150 of the motor 15 that is disposed at the bottom in the shell 1 simultaneously.Its tension force is given by dance roller 14 in endless belt 16.In addition, driving air-breathing fan belt 21 with fan F is erected on the gyroaxis 150 of above-mentioned motor 15.
Accommodate above-mentioned air-breathing fan guard 22 with fan F and be fixed in the rear wall 11 of shell 1 by installing plate 18, the air entry 220 of this fan guard 22 is relative with the aperture group zone 101 of the central portion of the inner panel that is formed at cylinder 10 from the rear simultaneously.In addition, be connected with the aiutage 12 that is connected with atmosphere, in this aiutage 12, dispose exhaust gas temperature sensor S2 as mentioned above at the outlet 221 of fan guard 22.In addition, the face portion in aperture group zone 101 is covered by gined cotton filter 23.
In this device, when the burning of the revolution of motor 15 and gas burner 31a begins, make air-breathingly by the fan belt 21 of the gyroaxis 150 that is erected on motor 15 and endless belt 16, discharge gas from the burning of gas burner 31a simultaneously and be discharged in the atmosphere with fan F → outlet 221 → aiutage 12 through hot gas duct 32 → warm-air supply mouth 30 → cylinder 10 → aperture group zone 101 → air entry 220 → air-breathing with fan F and cylinder 10 revolutions.
[control operation]
In the control device (not shown) of above-mentioned clothes drying device, microcomputer is housed.This microcomputer has the control program of content shown in the flow chart of Fig. 1.Following flow chart according to Fig. 1 illustrates the operation of the clothes drying device of present embodiment.
When pressing the running switch 4 (with reference to Fig. 4) of the bottom that is arranged at shell 1, in the step ST1 of Fig. 1, motor 15 is driven, and is air-breathing with fan F and cylinder 10 revolutions.In addition, heating grade X is set to represent " the 8th grade " of the highest heating grade.
Then, in step ST2, the gas burner 31a of heater 31 is with heating grade X (being set to the 8th grade in step ST1) burning.Specifically, gas burner 31a burns with 3150Kcal.
Then, in step ST3, standby to setting-up time finishes.The standby of carrying out setting-up time is that the relativeness for the detected temperatures of waiting for clothing temperature sensor S1 and exhaust gas temperature sensor S2 tends towards stability.
Next, in step ST4, judge whether M such as clothing are drying regime.Specifically, contact with electrode with the state of the electrode K1, the K2 that cross over electrode sensor S3 by cylinder 10 revolution and the M such as clothing that stir, and then judge whether drying is finished.When being drying schedule number when above by the power on signal number in the setting-up time of this electrode sensor S3 output (number of signals that electric current flows through between expression electrode K1, K2), be judged as not drying regime, and when the not enough drying schedule of above-mentioned power on signal number was counted, the judgement drying was finished.
Next, in step ST5, judge whether the clothing temperature that clothing temperature sensor S1 is detected reaches t ℃ of clothing critical temperature (corresponding with " the 1st critical temperature " of the specific item of described invention), or whether the detected temperatures of exhaust gas temperature sensor S2 reaches 65 ℃ of exhaust critical temperatures.In addition, t ℃ of above-mentioned clothing critical temperature, specifically, refer to than the quantity combusted with gas burner 31a described later when the 7th grade is adjusted downward to the 6th grade, 101 ℃ of low slightly temperature of clothing critical temperature.
As shown in Figure 2, under the M such as clothing with standard volume pack the situation of cylinder 10 into, begin the initial stage at gas burner 31a with the running that the 8th grade of L8 of the highest heating grade (state of heating grade X=8) burns, the heat of discharging gas from the burning of gas burner 31a is absorbed by M such as clothings mostly, so it is big that the rising gradient of the clothing temperature T 1 that is detected at this running beginning initial stage clothing temperature sensor S1 becomes; And, consumed heat, so the rising gradient of the temperature (delivery temperature) of the wet air that exhaust gas temperature sensor S2 is detected diminishes by the heat of evaporation of the large quantity of moisture among the M such as the heat absorption of M such as above-mentioned clothing and this clothing.Promptly, the rising gradient of the former clothing temperature is bigger than the rising gradient of the temperature (delivery temperature) of the latter's wet air.In the stage at operation beginning initial stage, in the time can confirming that clothing temperature that above-mentioned clothing temperature sensor S1 is detected rises to t ℃ of clothing critical temperature by step ST5, be used to make the value of heating grade X only to reduce the calculation " X=X-1 " of " 1 " by step ST6, thus, the value of heating grade X becomes " 7 ".Then, make gas burner 31a burning (with reference to step ST7) with this heating grade X (in step ST6, becoming " 7 ") that has reduced.Specifically, gas burner 31a is burnt with 2750Kcal, prevent thus by harmful effects (also being same below the 6th grade) such as the overheated caused variable color of M such as clothings.In addition, when execution in step ST5, under the temperature of the wet air that exhaust gas temperature sensor S2 is detected reached situation more than 65 ℃, also execution in step ST6, ST7 made the heating grade downward modulation one-level of gas burner 31a, burn with 2750Kcal.When the temperature of the wet air of discharging from aiutage 12 surpasses 65 ℃, might become easily in the cylinder 10 and will heat the condition of high temperature that the harmful effect that is brought acts on M such as clothing, so based on security consideration, the heating grade of downward modulation gas burner 31a.
Then, after 1 minute, carry out the dry judgement of finishing in step ST8 standby at step ST9.This drying is finished the control that is judged to be with the same content of described step ST4.In addition, also not necessarily leave no choice but to be provided with the control program of the standby in 1 minute of step ST8, also can be behind step ST7 directly the drying of execution in step ST9 finish judgement.
In step ST9, do not finish drying if judge, judge in step ST10 then whether the clothing temperature that clothing temperature sensor S1 is detected rises to 101 ℃ of clothing critical temperatures (corresponding with " the 2nd critical temperature " of the specific item of described invention), or judge whether the detected temperatures of exhaust gas temperature sensor S2 rises to 65 ℃.At this, gas burner 31a with the clothing critical temperature in the 7th grade of when burning above-mentioned 101 ℃ than gas burner 31a above-mentioned t ℃ high slightly of the clothing critical temperature during with the 8th grade of burning.Therefore, heater 31 with above-mentioned the 8th grade of L8 heated state under, after clothing temperature that clothing temperature sensor S1 is detected rises to t ℃ of clothing critical temperature, during downward modulation heating grade, even above-mentioned clothing temperature has surpassed t ℃ of clothing critical temperature, produce toning, also needn't too worry following situation, promptly, 101 ℃ of the clothing critical temperatures of the 7th grade of L7 of the heating grade reduced when surpassing after changing initial temperature detection of heating grade and continue to heat up.Therefore, as shown in Figure 2, gas burner 31a burns reliably with the 7th grade of L7, is difficult to occur existing example (the clothing critical temperature all is set at 101 ℃) heating grade such, gas burner 31a is as shown in Figure 5 reduced 6 grades of L6 of two grades to the from the 8th grade of L8 danger.Thus, compare, owing to can there not be the problem of skipping the 7th grade of L7,, just can keep the high temperature of M integral body such as clothing so when drying is moved, do not need excessively to reduce the heating grade of heater 31 with the existing example of Fig. 5.Thus, not only surface, its central part of M such as this clothing also can be kept high temperature, can be dried to this central part fully, prevent dry inequality.
In the time can confirming that clothing temperature that clothing temperature sensor S1 is detected rise to 101 ℃ of clothing critical temperatures by step ST10, control operation is back to step ST6.
In addition, when M such as judging clothing in step ST4, ST9 is drying regime, in step ST11, make the gas burner 31a of heater 31 flame-out.After this, make cylinder 10 and air-breathing usefulness fan F action after 1 minute, the buzzer that sounds is reported drying and is finished (step ST12, ST13).
In addition, carry out at cylinder 10 that M such as a spot of clothing are packed under the situation of dry operation, the heat of discharging gas from the burning of gas burner 31a consumes on M such as heats laundry hardly, so the delivery temperature that exhaust gas temperature sensor S2 is detected promptly rises to exhaust critical temperature (65 ℃).Therefore, carrying out under a small amount of dry situation, in fact, mainly is according to the generate heat control of grade of the delivery temperature that exhaust gas temperature sensor S2 is detected.
In addition, in the above-described embodiments, though the clothing critical temperature beyond the clothing critical temperature of grade when the 8th grade switches to the 7th grade that will generate heat is set at 101 ℃, this clothing critical temperature is not defined as 101 ℃.
