Technical field

The invention belongs to the field of clothes dryers, in particular to a control method of a quick clothes dryer and a quick clothes dryer.

Background technique

Nowadays, the rhythm of people's social life is getting faster and faster. Sometimes it is necessary to quickly dry the clothes to achieve ready-to-wear, while avoiding wrinkles and affecting the appearance.

The existing household clothes drying device is mainly a drum type clothes dryer. In use, the washed clothes are put into the drum, and the drum rotates to stir the clothes, and at the same time, hot air is blown into the drum to dry the clothes. The main problem of this type of drying device is that it is designed to dry a large amount of clothes, the drying speed is slow, the clothes are accumulated in the cylinder, the drying degree of the clothes is not easy to control, and the outer clothes may be dry, but the inner clothes are not dried, and the clothes are squeezed each other. It is easy to produce wrinkles; the above-mentioned drying method relies on the drum to agitate the clothes, which easily causes the clothes to wear.

Patent CN01215349.4 provides a fully automatic gas dryer, which consists of a barrel body and a front support plate fixed to the casing, the barrel body and the front support plate are in a dynamic fit, and the front support plate is provided with clothes. Temperature thermistor, and the thermistor in the air inlet channel, but in this structure, when the exhaust port temperature and the laundry temperature are lower than the set temperature, the heating is continued, if the exhaust port temperature and the laundry temperature are higher than a certain setting At the temperature, the proportional control valve is gradually closed or until the gas switching valve and the proportional control valve are closed. In this structure, the gas switching valve and the proportional control valve are controlled by the comparison between the temperature of the laundry and the preset value, thereby adjusting the temperature, but It does not have the function of judging the degree of dryness of the clothes, and realizes the function of automatically controlling the drying process.

The present invention has been made in view of the above.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a quick drying machine control method and a quick clothes dryer for judging the degree of drying of clothes according to the temperature of the clothes and the temperature of the drying gas, and the control method The temperature of the clothes and the temperature of the drying gas are integrated, and the control is more reasonable and accurate.

In order to solve the above technical problems, the basic idea of adopting the technical solution of the present invention is:

A control method of a quick clothes dryer, which determines the dryness of the clothes according to the temperature of the clothes and the gas temperature of the drying wind, and controls the drying process.

During the drying process of the clothes, the moisture in the clothes is evaporated by heat, and the evaporation of the water takes away a large amount of heat, so that the temperature of the clothes is in a lower range. As the moisture in the laundry decreases, the temperature of the laundry gradually rises when the moisture in the laundry is completely or almost After all evaporation, the temperature of the laundry will be close to the temperature of the drying wind, indicating that the laundry has been dried, and the dryer determines the dryness of the laundry according to the temperature of the laundry and the temperature of the air of the drying wind. Preset the temperature in the dryer, compare the temperature of the laundry with the preset temperature, and set the mode (value) to be single. It cannot be adjusted according to the actual use or environmental conditions. The adaptability is poor, and the temperature of the clothes and the gas of the drying wind are The temperature is compared, the principle is more reasonable, and the control is more accurate.

The dryer calculates the temperature difference between the gas temperature and the laundry temperature, determines the degree of drying of the laundry based on the temperature difference, and controls the wind speed of the drying wind and/or the temperature of the drying air and/or the closing of the dryer during the drying process.

By calculating the temperature difference between the gas temperature and the laundry temperature, when the temperature difference is large, it indicates that the clothes are not dry yet, and the temperature difference can be used as the basis for controlling the wind speed and the temperature, so that the drying process is more intelligent, and the clothes are baked. The drying speed is faster. When the difference is 0 or the difference is very small, it indicates that the clothes have been dried and the dryer is controlled to be closed. The control method is more accurate in controlling the drying process, and the drying machine has a wider application range. .

The difference between the preset gas temperature and the laundry temperature of the clothes dryer is ΔT. According to the gas temperature value T1 and the laundry temperature T2, T1-T2 is calculated and compared with ΔT. If T1-T2≥ΔT, the drying is continued. If T1-T2 < ΔT, the drying is ended.

By presetting the difference ΔT in the dryer, the actual temperature difference between the calculated gas temperature value T1 and the laundry temperature T2 is compared with the preset ΔT, thereby realizing the automatic closing of the dryer, which is more intelligent and more convenient to use. .

The dryer presets a time threshold or a temperature threshold for calculating a difference between the gas temperature T1 and the laundry temperature T2, and when the time reaches the time threshold or the temperature rises to the temperature threshold, the dryer calculates the temperature difference T1-T2.

Since the temperature of the clothes and the temperature of the drying wind are both in the low temperature range at the beginning of the dryer, the difference between the two may be small, which may cause misjudgment of the dryer. By preset the time threshold or the temperature threshold, when the temperature or time reaches the threshold, the calculation of T1-T2 is performed to reduce the possibility of misjudgment of the dryer, so that the judgment is more accurate and reasonable, and the dryer is more intelligent.

The dryer pre-determines the minimum temperature Tc of the drying wind for calculating T1-T2. If T1 ≤ Tc, T1-T2 is not calculated and the drying is continued. If T1>Tc, the temperature difference T1-T2 is calculated.

After a period of startup, the drying air is heated to Tc, and the difference between T1 and T2 is very different, which eliminates the possibility of misjudgment when the temperature is low.

The dryer determines whether the drying air is overheated according to the gas temperature T1, and if it is overheated, reduces the temperature of the drying air.

The dryer determines whether the temperature of the drying air is too low according to the gas temperature T1, and if it is too low, raises the temperature of the drying air.

During the entire drying process, the dry clothes temperature is too high to increase the drying speed, but may cause damage to the clothes. For dryers that dry clothes by airbags, the temperature of the drying air is too high. When a person touches or is in the vicinity, it is easily burnt by the hot steam or the hot steam brought out by the drying wind. By judging the inside of the dryer Whether the temperature of the drying air is too high or too low will be baked The temperature of the dry wind is controlled at a suitable temperature to meet the needs of quick drying and to prevent burns.

The clothes dryer includes a heating device for heating the drying wind and a blowing device for conveying the drying wind. When the laundry is dried, the dryer controls the heating device to be turned off first, and the air blowing device is closed.

When the drying is completed, the heating device is turned off first, and the air blowing device is closed, so that the heated drying air is completely discharged, thereby reducing damage to the heater or the dryer.

The control method includes the following steps:

S10, turning on the clothes dryer;

S20, the dryer detects the gas temperature T1 of the drying wind;

S30, comparing T1 with Tc, when T1≤Tc, heating is continued, and when T1>Tc, then running S40;

S40, the clothes dryer detects the laundry temperature T2, compares the difference between the preset gas temperature and the laundry temperature ΔT and T1-T2, and when T1-T2≥ΔT, continues to compare the sizes of T1-T2 and ΔT. When T1-T2 < ΔT, the heating device and the air blowing device of the dryer are turned off, and the drying is completed.

A quick-drying machine having the above control method, comprising a base, an air bag provided on the base for drying clothes, and a drying device for providing a drying wind for the air bag, and a device for detecting the temperature of the drying air a first temperature detecting device, a second temperature detecting device for detecting the temperature of the laundry, and a control device, wherein the first temperature detecting device, the second temperature detecting device and the drying device are electrically connected to the control device, and the control device is based on the drying air temperature And the clothes temperature control drying device.

The above drying method is particularly suitable for a clothes dryer having an air bag. Since the drying air passes through the air bag to dry the clothes, the moisture on the clothes is taken away, and the drying wind in the air bag and the detection of the temperature of the clothes are more affected. small. For the drum type dryer, the clothes are located in the drying air, and the drying wind has a greater influence on the temperature of the clothes, and the judgment error is large. In the structure, a first temperature detecting device and a second temperature detecting device are provided to detect the gas temperature and the laundry temperature of the drying wind, respectively, and the control device controls the drying device according to the drying air temperature and the laundry temperature.

After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: in the drying process of the laundry, the moisture in the laundry is evaporated by heat, and the evaporation of the water takes away a large amount of heat, so that the temperature of the laundry is in a lower range. As the moisture in the laundry decreases, the temperature of the laundry gradually rises. When the moisture in the laundry is completely or almost completely evaporated, the temperature of the laundry approaches the temperature of the drying wind, indicating that the laundry has been dried, and the dryer is based on the temperature of the laundry. And the temperature of the gas to dry the wind, to determine the degree of dryness of the clothes. The temperature is preset in the dryer, and the temperature of the laundry is compared with the preset temperature to realize the control. However, the control method discharges all the environmental factors, and the adaptability is poor, and the temperature of the laundry is compared with the gas temperature of the drying wind, and the principle is more reasonable. The control is more accurate; by calculating the temperature difference between the gas temperature and the laundry temperature, when the temperature difference is large, it indicates that the clothes are not dry yet, and the temperature difference can be used as the basis for controlling the wind speed and the temperature, so that the drying process is more Wisdom Yes, and the drying speed of the clothes is faster. When the difference is 0 or the difference is very small, it indicates that the clothes have been dried and the dryer is controlled to be closed. The control method is more accurate in controlling the drying process, and the actual environment will be And a variety of factors are taken into consideration, dryers have a wider range of applications.

The specific embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

detailed description

The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.

Embodiment 1:

As shown in FIG. 1 to FIG. 2, a control method of the quick clothes dryer, the clothes dryer judges the dryness of the clothes according to the temperature of the clothes and the gas temperature of the drying wind, and controls the drying process.

During the drying process of the clothes, the moisture in the clothes is evaporated by heat, and the evaporation of the water takes away a large amount of heat, so that the temperature of the clothes is in a lower range. As the moisture in the laundry decreases, the temperature of the laundry gradually rises. When the moisture in the laundry is completely or almost completely evaporated, the temperature of the laundry approaches the temperature of the drying wind, indicating that the laundry has been dried.

The clothes dryer determines whether the temperature of the clothes is equal to the gas temperature of the drying wind or whether the temperature of the clothes is close to the gas temperature, determines the degree of drying of the clothes, and detects whether the clothes are finished. The determination method is more reasonable, and the clothes dryer is dry. Process The judgment is more accurate.

This structure is particularly suitable for a clothes dryer having an air bag 8, which includes an air bag 8 for supporting and drying the laundry, and a drying device that blows the drying air into the air bag 8, and the detected gas temperature is inside the air bag 8. The gas temperature or the temperature of the gas in the air duct of the drying device, and the temperature of the laundry detects the temperature of the laundry on the airbag 8. Since the drying air takes away the moisture from the laundry during the drying process, the temperature of the laundry is lowered, and the temperature is lowered. The means for detecting the temperature of the gas is generally disposed at a position away from the airbag, and the detecting end of the device for detecting the temperature of the laundry is generally opposed to or inserted into the laundry, and the temperature of the gas in the airbag 8 has less influence on the temperature of the laundry, and the determination is more accurate.

The dryer calculates the temperature difference between the gas temperature and the laundry temperature. When the temperature difference is equal to 0, that is, the gas temperature is equal to the temperature of the laundry, it indicates that the laundry has completely dried, it is judged that the drying is completed, and the dryer is controlled to be closed.

It is also possible to calculate the temperature difference between the two based on the gas temperature and the temperature of the laundry, and then compare the calculated temperature difference twice. When the temperature difference between the two is constant, it indicates that the laundry has dried.

The dryer can also calculate the temperature difference between the gas temperature and the laundry temperature. When the temperature difference is large, increase the wind speed of the drying wind and/or the temperature of the drying wind, and accelerate the drying speed. When the temperature difference is small, adjust The wind speed of the small drying wind and/or the temperature of the drying wind controls the drying process.

It is also possible to preset a smaller temperature difference range or temperature value. When the difference between the gas temperature and the laundry temperature is within the preset temperature range or less than the preset temperature value, the logo drying is completed, and the dryer is controlled. shut down.

Further, the dryer presets a difference ΔT between the gas temperature and the laundry temperature, calculates T1-T2 according to the gas temperature value T1 and the laundry temperature T2, and compares the obtained result with a preset ΔT, if T1- When T2 ≥ ΔT, the drying is continued. If T1-T2 < ΔT, the heating device 4 and the air blowing device 2 of the clothes dryer are turned off to control the drying process.

The control device 5 of the clothes dryer calculates T1-T2 and compares the obtained result with ΔT. When T1-T2≥△T, it indicates that the clothes have not been dried yet, and then continue drying, at intervals, and then The temperature of the gas detected by the dryer is different from the temperature of the laundry. The value of T1-T2 obtained is compared with ΔT. If T1-T2≥△T, the drying is continued until T1-T2<ΔT, indicating clothing. The water content in the water is small, the evaporation of water is small, the clothes have been dried, and the control device 5 of the clothes dryer turns off the heating device 4 and the air blowing device 2 of the clothes dryer.

Further, when the dryer is turned off, the control device 5 first controls to turn off the heating device 4, and then controls to turn off the air blowing device 2. If the air blowing device 2 is turned off first or both are turned off, the vicinity of the heating device 4 appears. The temperature is not easily dissipated, affecting the service life of the heating device 4, first turning off the heating device 4, and discharging the remaining temperature of the heating device 4 through the air blowing device 2, Prevent damage to the heating device 4 and the dryer.

Further, before calculating T1-T2, a precondition for performing the above calculation is preset: a time threshold or a temperature threshold for calculating the difference T1 - T2 between the gas temperature T1 and the laundry temperature T2 is preset, when the time reaches the time threshold or the temperature reaches At the temperature threshold, the dryer calculates T1-T2 and compares T1-T2 with ΔT.

At the beginning of the dryer, the temperature of the clothes and the temperature of the drying air are in the low temperature range. The values may be very close, which may result in the judgment result being T1-T2<△T, causing the dryer to make a wrong judgment and execute. The heating device 4 and the air blowing device 2 of the dryer are turned off, so it is necessary to set a prerequisite for performing the calculations T1-T2.

The precondition may be a preset temperature threshold in the dryer. When the temperature of the drying wind of the dryer is less than the temperature threshold, the calculation T1-T2 is not performed, when the temperature of the drying wind is greater than the temperature threshold. , then calculate T1-T2.

Specifically, the minimum temperature Tc of the drying wind for calculating T1-T2 is preset, and if T1≤Tc, the calculation T1-T2 is not performed, and the drying is continued. If T1>Tc, the calculation T1-T2 is performed, and T1-T2 is compared with ΔT.

The precondition may also be a preset temperature threshold in the dryer. When the laundry temperature is less than the temperature threshold, the calculation T1-T2 is not performed, and when the laundry temperature is raised to be greater than the temperature threshold, the T1 is calculated. -T2.

The precondition may also be a preset time threshold in the dryer, and calculate the drying time t of the dryer after starting the machine. When t is greater than the preset time threshold, calculate T1-T2; when t is less than the time threshold When the temperature of the dryer may not be stable, the dryer does not calculate T1-T2 and continues to dry the clothes.

During the entire drying process, the dry clothes temperature is too high to increase the drying speed, but may cause damage to the clothes. There is another drawback to the dryer for drying clothes by the air bag 8. When the temperature of the gas is too high, the user is easily burned when the user touches the air bag 8 or the clothes, especially for children, the danger is too high.

The clothes dryer determines whether the drying air is overheated according to the gas temperature T1, thereby controlling the opening and closing of the heating device 4 of the clothes dryer or adjusting the heating power of the heating device 4 of the clothes dryer;

Further, the maximum temperature Tb is preset, and when T1>Tb, the heating device 4 is turned off or the heating power of the heating device 4 is reduced.

In the drying process, the maximum temperature Tb is preset, and when the gas temperature T1>Tb, the heating device 4 is turned off or the heating power of the heating device 4 is reduced, and the temperature of the drying air is lowered.

The dryer determines whether the temperature of the drying air is too low according to the gas temperature T1, thereby controlling the opening and closing of the heating device 4 or adjusting the heating power of the heating device 4 of the dryer;

Further, when the gas temperature T1 < the lowest gas temperature Ta, the heating power of the heating device 4 is increased or the heating device 4 is restarted.

When the heating device 4 is turned off or the heating power of the heating device 4 is reduced for a period of time, the temperature of the drying air gas is lowered, and if the gas temperature is too low, it is disadvantageous for drying the laundry quickly, and therefore, by setting the minimum gas temperature Ta, when the gas When the temperature T1 < the lowest gas temperature Ta, the heating power of the heating device 4 is increased or the heating device 4 is restarted to increase the temperature of the drying air.

Through the above adjustment process, the temperature of the drying gas can be controlled to a relatively suitable temperature range, which can meet the requirements of quickly drying clothes without causing danger due to excessive temperature.

Embodiment 2:

As shown in FIG. 1, a method for controlling a quick-drying machine includes the following steps:

S10, turning on the clothes dryer;

S20, the dryer detects the gas temperature T1 of the drying wind;

S40. The clothes dryer detects the laundry temperature T2, and compares the preset gas temperature to the temperature difference ΔT of the laundry temperature and T1-T2. When T1-T2≥ΔT, the comparison of T1-T2 and ΔT is continued. The size, when T1-T2 < ΔT, turns off the heating device 4 of the dryer and the air blowing device 2, and the drying is completed.

Embodiment 3

As shown in FIG. 2, a quick clothes dryer having the control method of the first embodiment to the second embodiment includes a base 1, an air bag 8 disposed on the base 1 for drying clothes, and a drying machine for the air bag 8. Wind drying device, first temperature detecting device 9 for detecting drying air temperature, second temperature detecting device 10 for detecting laundry temperature, and control device 5, first temperature detecting device 9, second temperature detecting device Both the drying device 10 and the drying device are electrically connected to the control device 5, and the control device 5 controls the drying device according to the drying air temperature and the laundry temperature.

Specifically, the drying device includes an air blowing device 2 disposed in the base 1 , and the air blowing device 2 blows the drying air into the air bag 8 , and the air blowing device 2 communicates with the air bag 8 through the air channel 3 , and the air channel 3 A heating device 4 is provided, and the heating device 4 heats the drying air to increase the temperature of the drying air.

Further, the first detecting device is disposed in the air duct 3 or in the air bag 8, and the second detecting device is disposed on the air bag 8, and the detecting end is in contact with the clothes;

The first detecting device and the second detecting device are both temperature sensors, the air blowing device 2 is a blower, and the heating device 4 is a heater.

Further, the airbag 8 is provided with a support structure, and the lower end of the support structure is supported on the base 1 or the outlet of the air duct 3, and the upper end In opposition to the airbag 8, the first temperature detecting means 9 is disposed on the support structure and spaced apart from the airbag 8, and the second temperature detecting means 10 is disposed on the support structure and the detecting end is in contact with the laundry through the airbag 8.

Further, the support structure comprises a crossbar 7 for unfolding the laundry and a longitudinal rod 6 for supporting the laundry. The lower end of the longitudinal rod 6 is supported by the outlet on the outlet of the air duct 3, and the upper end is screwed to the crossbar 7, A temperature detecting device 9 is disposed on the longitudinal rod 6, the second temperature detecting device 10 is disposed on the crossbar 7, and the detecting end of the second temperature detecting device 10 is in contact with the laundry through the airbag 8, since the shoulder of the clothing is generally not too It is easy to be dried, and the second temperature detecting device 10 is set at this position, and it is possible to ensure that the laundry is completely dried.

Of course, the structure of the airbag 8 can also be changed in the following manner, so that the various parts of the laundry are simultaneously dried, and the setting position of the second temperature detecting device 10 is no longer limited.

As shown in FIG. 3, a plurality of air outlet portions 11 are provided on the airbag 8, and the air outlet portion 11 corresponds to a portion where the multi-layer fabric on the dried laundry overlaps or corresponds to a portion where the filler is provided on the laundry, because the clothes The portion where the upper multi-layer fabric overlaps or the portion where the filler is provided on the laundry is not easily dried, and becomes a key factor for restricting the overall drying efficiency of the laundry. By using the air outlet portion 11 corresponding to the above portion, the air outlet portion is utilized. The high gas permeability of 11 increases the gas flow rate, increases the convective heat transfer, achieves targeted drying of the clothes, and improves the overall drying speed of the clothes.

The airbag 8 is matched with the shape of the dried laundry to make the garment more conformable to the airbag 8, facilitating heat transfer and flattening.

The shape of the airbag 8 may be a humanoid airbag 8, a top garment airbag 8, or a pants airbag 8 to accommodate differently shaped garments.

The material of the airbag 8 is made of an elastic material. When the airbag 8 is charged, the elasticity of the airbag 8 is more favorable for the airbag 8 to stretch the clothes, thereby reducing the wrinkles on the clothes, and the volume of the elastic airbag 8 varies widely. Different types of clothing, such as XS-XXXL type clothes can be dried.

The airbag 8 can also be made of a gas-impermeable material, and the drying of the airbag 8 by the body of the airbag 8 is only through heat conduction, without convective heat transfer, and the drying speed is relatively slow, and more preferably made of a gas-permeable elastic material. 8 The gas permeability of the body is smaller than the gas permeability of the air outlet portion 11, so that the gas can swell the air bag 8, and the body of the air bag 8 has gas permeability, and the gas in the body portion of the air bag 8 flows and heats and dries the clothes, so that the drying speed of the clothes is faster.

The venting portion 11 is located at the shoulder and/or cuff portion of the humanoid airbag 8 and/or the collar portion and/or the pocket portion and/or the waistband portion and/or the trousers and/or the zipper portion, due to the collar, cuffs of the garment, The position of the pocket, the button button area, the zipper area or the shoulder is composed of a plurality of layers of cloth. When drying, the position of the single layer of cloth is not easily dried; and if the collar is provided with a lining, the shoulder is set. The shoulder pad is more difficult to dry at the shoulder and the collar position, and the air outlet portion 11 having good air permeability is disposed at these portions of the human air bag 8, and the drying rate of the position on the clothes is improved by using the good air permeability. To increase the drying rate of the entire garment.

The shoulder and/or cuff portion and/or the collar portion and/or the pocket portion and/or the waist portion and/or the pant and/or the zipper portion of the humanoid airbag 8 are each formed of a material having a higher gas permeability to form a wind. The cloth 11 and the air bag 8 can be connected by means of bonding, integral molding or stitching, for example, the air outlet portion 11 is made of a cloth having good air permeability, so that the air permeability of the air outlet portion 11 is higher than that of the air bag body 8. The air volume of the air outlet portion 11 is increased, and the drying efficiency is improved. The air outlet portion 11 is made of a cloth having good air permeability, and the airbag 8 is relatively closed inside and outside, thereby reducing the entry of debris, reducing the cleaning frequency of the airbag 8, and reducing the airbag. 8 wear and tear.

Each of the air outlet portions 11 may be made of the same gas permeable material, or may have different gas permeability, and the breathable material of the shoulder portion, the cuff portion, the collar portion, the pocket portion, the waist portion, the hem portion, and the zipper portion of the humanoid airbag 8 may be The gas permeability is different, and the gas permeability of the gas permeable material gradually increases as the number of layers of the fabric increases or the thickness of the filler on the garment increases, due to the shoulder, the cuff portion, the collar portion, the pocket portion, the waist portion, and the pants side of the garment. The composition and material of the zipper are not exactly the same. For example, the collar, cuffs, pockets, button areas, shoulders, etc. of the clothes are generally composed of multiple layers of fabric, which are not easily dried, and the collar is often kept in shape. The lining material is provided with a shoulder pad for maintaining the shape of the shoulder, and these parts are more difficult to dry. Therefore, in addition to providing the air outlet portion 11 at the above-mentioned non-drying portion to increase the drying speed, it is further difficult to dry according to these non-drying positions. The degree of ventilation of the air outlet portion 11 is further differentiated, for example, the air permeability of the collar portion and/or the shoulder portion of the humanoid airbag 8 is further improved, and the drying speed is improved. Increases with an increase of filler thickness of layers of fabric or clothing is gradually increased permeability of the permeable portion.

The above control method of the quick dryer:

As shown in Fig. 1, after the dryer starts working, the blower and the heater are turned on, the heater heats the air blown into the airbag 8, and the blower sends the heated drying air into the airbag 8, as the heater works. The temperature of the air in the airbag 8 is gradually increased, the first temperature sensor detects the gas temperature T1 of the drying wind, and transmits the temperature information to the control device 5, and the control device 5 monitors the temperature value T1 detected by the first temperature probe. T1-T2 is calculated when T1>Tc (Tc can select a value in the range of 40-60 °C, preferably 50 °C). The dryer is preset to ΔT, generally ΔT is between 3-5 ° C, preferably 4 ° C. The dryer compares T1-T2 with ΔT as a basis for judging the drying of the clothes: when T1-T2≥ΔT, continue heating, calculate T1-T2 again, and compare T1-T2 with ΔT, when T1-T2 <ΔT, the dryer and blower of the dryer are turned off, and the drying is completed.

When the heater and the blower are turned off, the control device 5 sequentially controls the heater to stop working, the fan stops working, and a prompt message (a prompt or a display prompt) is issued, and the drying process ends.

In the whole drying process, in order to ensure a faster drying speed and prevent the surrounding people, especially children, from accidentally contacting the surface of the airbag 8 to be burnt, the maximum temperature Tb and the minimum gas temperature Ta which can be reached by the drying wind are set, and the temperature is set. The range is set to 60-70 ° C, preferably 64-66 ° C.

When the temperature of the drying air reaches Tb (Tb temperature is preferably 66 ° C), the heater stops or reduces the heater power, the air temperature in the air bag 8 drops, and when the temperature drops to Ta (Ta is preferably 64 ° C), heating The device is then turned on or the heater power is turned up, so that the air temperature in the air bag 8 is controlled to be in the range of 64-66 ° C.

The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and any technology that is familiar with the present patent.
