Description
Technical field
The present invention relates to a kind of safety guard of bedding fast-drying device, is at the fixing frame structure surface reload temperature monitoring regulation device of heater of the device interior that hot blast is provided specifically.
Background technology
Bedding fast-drying device is by providing the fan heater of hot air source to combine with the middle bag-shaped pad of bed clothes that is laid in of being made by textiles; in fan heater, for supporting design and installation on the micarex of heater, there are the overtemperature protection systems such as thermostat and thermal cut-off, closely directly for heater temperature, monitor and limit.This technical scheme directly transplanting is in traditional household heater, according to corresponding household heater national standard requirement, household heater device body influential position must mark " forbidding to cover " printed words, the temperature increasing degree of air outlet periphery under normal operation is also had to clearly restriction and examination criteria, reason is if the normal heat radiation of machine is obstructed, to cause built-in temperature to raise rapidly, and directly cause mechanical disorder, serious also can cause security incident.Diversely with conventional chamber internal heater using method be, fan heater for bedding flash baking must be socketed at air outlet place bag-shaped pad, from occupation mode, can conclude, occupation mode and technical standard judgement with traditional household heater, machine is overheated in fact has been transformed into normality from fortuitous event in bedding fast-drying device course of normal operation! Therefore directly transplanting is in the overtemperature protection system of traditional household heater, the security protection needs of bedding fast-drying device cannot have been met, its defect is if the household heater with traditional that operating temperature arranges is the same high, once there is non-normal use situation, heat cannot smooth and easy timely discharge in machine, and built-in temperature can sharply raise, and high temperature can cause in fan heater components and parts overheated impaired, fan heater causes working of plastics distortion, until cannot continue to use; If operating temperature arranges too low, by the speed of appreciable impact heating, drying and drying effect, particularly in winter of south China, indoor environment temperature can be low to moderate below 10 degree, if heating power is too low, the hot blast temperature blowing out is not high enough, is just difficult to play the object of Fast Heating bedding, and the moisture of wanting to dry in bed clothes is just extremely difficult especially as thought the boiled water flask of use lighter.If lacked rapid drying function, the effect of bedding fast-drying device is just equal to electric blanket; If firing rate is slow, bedding fast-drying device has more lost the comparative advantages with electric blanket.The technical scheme that the similar products such as the Guilt warming machine of selling on market adopt is to have to take the second best, setting is low to moderate the temperature limiting of 60 ℃, heating power is low to moderate 600-700W, some types for promote heating power even specially for be easily subject to high temperature injury part design Special heat dissipating fan, work out so-called double fan fan heater, this is like building a dam in barrier lake downstream, and consequence is well imagined.As can be seen here, transplant the method for directly monitoring and limiting for heater temperature in conventional chamber internal heater, owing to cannot all unusual conditions being carried out to simulated test, it is foundation that the operating temperature of setting mainly be take technical staff's experience, think at a certain temperature to be " safe temperature ", surpass a certain temperature and be considered to impact safe handling, subjective colo(u)r is dense, lack objective basis for estimation, if there is operating temperature in practical application, set too high impact safe handling, if it is too low that operating temperature is set, the contradiction that cannot be in harmonious proportion of image firing rate and drying effect.
The present invention has with applicant the technical scheme that Patent right " warm air cushion " (patent No.: ZL2004 1 0085370.6) patent of invention complete sets of Techniques is used." warm air cushion " patent of invention technology of applicant has thoroughly solved the technical barrier of the smooth and easy discharge of high-power heating heat of bedding fast-drying device.But this refers to according under the prerequisite of product description proper operation.If when violating correct operating procedure or occurring fortuitous event, the heat producing because of heater cannot smooth and easy timely discharge, the instantaneous rising of warm braw built-in temperature, and high temperature can cause components and parts fault and working of plastics distortion in machine.In order to reduce fault rate repair rate, improve customer satisfaction, the every aspect that our oral prompting in product description, fan heater shell full position, propaganda material, webpage and process of exchange etc. can be expected has been done the time, even if like this or cannot guarantee the attention that causes that all clients are enough.Market feedback information let us is for many years recognized: if could continue the consequence of use after will bearing that parts are impaired and must keeping in repair because of client's maloperation, little error, the accident that accidentally occurs, no matter for the volume production of product, or the penetration and promotion of product all can have a negative impact.Because the not smooth excess Temperature of the inner heat extraction of fan heater causes this persistent ailment of mechanical disorder to perplex us for many years, become us least to wish to encounter the technology barrier that but always cannot get around.
Summary of the invention
The object of the invention is to design a kind of brand-new safety guard, the hot blast temperature that allows fan heater blow out in normal operating conditions is enough high, and firing rate is enough fast, and drying effect exceeds user's expection, not injuring under the prerequisite of bedding physical properties of fabric, promote to greatest extent heating power; Once and there is abnormal operating state in fan heater; this brand-new safety guard can be made logic judgement in advance; before reaching far away the hurtful height of fan heater components and parts, built-in temperature starts rapidly; cut off the electricity supply; stop heating; guarantee not occur security incident; guarantee that fan heater can not be subject to high temperature injury; and after this brand-new safety guard starts; user only need pull up attaching plug; get rid of and cause after the reason of non-normal working, plug-in can recover normal work again.
The brand new technical scheme of the safety guard of the bedding fast-drying device the present invention relates to can realize by following steps; at the fixing frame structure surface reload temperature monitoring regulation device of heater of the device interior that hot blast is provided, the operating temperature of this temperature monitoring regulation device is a little more than the temperature increasing degree on the frame structure surface of the fixedly heater recording under normal operation and the high ambient temperature sum of conventionally using bedding fast-drying device.Described the equipment of hot blast is provided can be at its air outlet position, to be designed with the fan-type fan heater warmer being suitable for bag-shaped pad syndeton, can be also by connector, to connect the fan-type fan heater warmer of bag-shaped pad.The described device interior that hot blast is provided the fixedly frame structure of heater can be guiding air channel.The described relative position of surperficial reload temperature monitoring regulation device the device interior guiding air channel of hot blast is provided is limited between the front and back end points that fixing heater is installed in guiding air channel.Described temperature monitoring regulation device can be fixed on the outer surface in guiding air channel, can be also to run through wind path wall.Described temperature monitoring regulation device can be hand-resetting.Described temperature monitoring regulation device can be temp probe, temperature controller, temperature limiter, thermal protector, thermal cut-off, Thermal Cutoffs, thermostat, temperature detect switch (TDS), thermistor.
Before the present invention determines final technical solution, we simulate various non-normal use situations, and to rapid wear components and parts with easily occur that the position of thermal deformation installs temperature detection device, gather mass data and compare, be that new technical solution is found breach.According to fan heater operation principle, no matter fan heater is that air-out is obstructed, or air intake is obstructed, or be that both have both at the same time, capital expanded motor operating load, motor surface temperature should have obvious rising, but actual monitoring shows, fan heater occurs that abnormal work state rear motor surface temperature rise does not obviously change, motor surface temperature does not have the corresponding rising of air themperature of random interior instantaneous rising yet, analyzing wherein reason should be higher with motor self temperature rise in normal operation process, the hot blast temperature having blown out with fan heater is very nearly the same, therefore not high to the hot blast susceptibility pouring in down a chimney under fan heater abnormal work state.When to abnormal work state, in the monitoring of fan heater internal gas flow temperature, find, gas flow temperature is with the lengthening of fan heater abnormal work time, indentation rises, analyzing wherein reason is that high temperature can cause the temperature controller startup on heater to stop heating, now motor continues operation blowing cold air, when built-in temperature reduces, reach after the reset temperature of temperature controller, warm air machine heater recloses power supply heating, so circulation.During abnormal operating state, in machine, air themperature eustasy is frequent, be quick on the draw, but be subject to fan heater internal structure design impact, the monitored data that different monitorings position obtains differs greatly, the reason difference that occurs abnormal work state also can cause monitored data to occur significant difference ... through long term monitoring and the analysis to monitored data, final technical solution has dropped on the guiding air channel in fan heater, monitored data shows, under normal heating state, can be over 20 ℃ for the fan heater guiding wind duct temperature increasing degree of testing, for example, while testing, environment temperature is 15 ℃, under normal heating state, the temperature recording on test machine guiding air channel is not subject to the laser heating time restriction all the time can be over 35 ℃.When there is abnormal operating state, test machine guiding wind duct temperature presents with the prolongation of abnormal work time the trend that straight line rises, and temperature increasing degree is obvious, and is not subject to the impact generation temperature fluctuation of temperature controller frequent starting, is easy to monitoring.Analyzing wherein reason, is mainly that the operating temperature of temperature controller on test machine heating frame is 85 ℃, and reset temperature is 60 ℃, and reset temperature is far above the temperature in test machine guiding air channel under normal heating state; Next heat that is high-power heater produces cannot smooth and easyly be discharged, the trend that built-in temperature raises fast can not change because of the frequent movement of temperature controller, until circuit is thoroughly cut off in thermal cut-off action, on test machine heating frame, the operating temperature of thermal cut-off is 145 ℃.In practical operation, indoor environment temperature below 20 ℃ according to proper operation step use test machine, the temperature increasing degree of guiding wind duct temperature is no more than 20 ℃, the actual temperature recording should be below 40 ℃, if there is abnormal work state, the temperature in guiding air channel will be over 40 ℃, and present linearity rising with the prolongation of abnormal work time.Normally in environment temperature, just there is necessity of using bedding fast-drying device under lower than 30 ℃ of conditions, we are loosened to 50 ℃ the operating temperature that is arranged on the monitoring temperature device on fan heater guiding air channel accordingly, once monitor temperature over 50 ℃, just can be from judging that in logic fan heater is in abnormal work state, cut off the electricity supply at once, stop heating, 50 ℃ from causing, fan heater components and parts are impaired to be also far away with temperature plastic body thermal deformation, is the temperature being perfectly safe.Accordingly; can on leading air channel, fan heater install operating temperature additional and be the temperature control device of 50 ℃; and this safety guard can be by pulling up attaching plug after starting; the reason that discharge causes unusual condition to occur; again the normal operation that the plug that plugs in again can recover fan heater, realizes object of the present invention.
The new technical scheme of the present invention is brought substantive breakthroughs from two aspects, a breakthrough is that brand new technical solution proposed by the invention is that when abnormal work is appearred in bedding fast-drying device, the secondary infringement information of association is monitored, by " logic analysis ", the appearance of non-normal working situation is made the objective judgement having scientific basis, accomplished accurate, find as early as possible, action in time, cut off the electricity supply rapidly and stop heating, the fault rate that non-normal working is caused is reduced to zero theoretically, thereby for strengthening heating power, improve the built-in temperature controller operating temperature of heating frame, allow fan heater blow higher safer hot blast safety guarantee is provided.Another breakthrough is that the operating temperature of this brand-new safety guard is far below the operating temperature of the built-in temperature controller of tradition heating frame; guarantee when abnormal conditions occur can not cause parts impaired by Yin Gaowen; and with hand-reset function; after startup; user only need pull up attaching plug; get rid of and cause abnormal factor; again plug-in can recover normal work; the elbow processed of the loaded down with trivial details using method operating procedure that perfection has been held back before having solved; allow product really realize simple to operate, easy to use, safe and reliable; sturdy durable, greatly promote user satisfaction.
