Description

Heater for sleeping

The present invention is a heater for sleeping, is characterized in that temperature adjustment is simple and easy to do.

We are that example illustrates existing heater for sleeping with the electric mattress, h.d., the person to go to bed is transferred to the high temperature scale to the thermoregulation knob of temperature setting device, about one hour of preheating, after treating that quilt is warm, again the thermoregulation knob of temperature setting device is transferred to suitable temperature scale.Therefore, particularly the elderly's trival matters are various, if health feels cold behind the last toilet of getting up at night, thermoregulation knob is not enough on this temperature still.In this case, health is promptly warm comes in order to make, and must be transferred to the high temperature scale to thermoregulation knob from this time, and electric mattress is heated up.But, carrying out high temperature in this way when setting, can not fall asleep before coming in that health is warm, because also will make knob return to original position through after the certain hour always.And be under knob is in the state of high temperature scale, just to fall asleep under many situations, waking up with after heat lowers temperature again.This situation is very disadvantageous for obtaining comfortable sleep.

As a kind of solution, the someone has proposed the high-temperature start-up mode.In other words, as long as click the high-temperature start-up switch of electric mattress controller, the position when the setting scale of knob just can remain on common sleep had both made the temperature of electric mattress in a single day be raised to high temperature, also can automatically drop to the temperature of knob scale.Knob-operated in the time of like this, just can making preheating becomes simple.Temperature recovery on also the someone considers to be used for the mode of this high-temperature start-up switch at night behind the toilet.The shortcoming of this mode is: in a single day electric mattress is raised to high temperature, and the person to go to bed can promptly place oneself in the midst of in the bedding of high temperature.Therefore, should avoid adopting this mode as far as possible.In addition,, perhaps make health too warm, utilize the quilt of electric mattress preheating will seem awfully hot owing to drinking or having a bath if room temperature is higher.In this case, must after being transferred to the low temperature scale, setting knob go to bed on the contrary.But to early morning can be frozen awakely again, must regulate the temperature setting knob again.And the elderly does not just see the literal on the knob if do not use presbyopic glasses, operation knob gropingly in the dream, and the result transfers temperature too highly, is exactly low, is difficult to the temperature that obtains suiting, and this is also very inconvenient.

United States Patent (USP) 4,277 discloses a kind of temperature control system that is used for electronic heating apparatus No. 670.This temperature control system comprises a device, and the temperature that detects heater when temperature sensor is lower than when temperature is set, and this device raises the temperature of heater to reach up to it temperature is set.But, this temperature control system is not provided with and heater is higher than be provided with the temperature of temperature to be reduced to the device that temperature is set, therefore, this temperature control system can not arbitrarily be adjusted the temperature of heater, thereby the user can not enjoy the comfort temperature that is fit to the arbitrary state of user.

The present invention makes every effort to eliminate these existing problems.Therefore, the object of the present invention is to provide heater for sleeping such as a kind of electric mattress like this, where necessary, can make the temperature of electric heater temporarily depart from the preference temperature that setting device sets and raise or reduce, can automatically return to original preference temperature then.So, easy to use, be easy to obtain comfortable sleep simultaneously.

In order to reach this purpose,, possess a kind of in the following circuit at least: to the switch on control circuit of control of electric heater according to heater for sleeping of the present invention; The temperature that above-mentioned electric heater is set from the said temperature setting device heats up in required time, and then returns to the intensification timing circuit of design temperature; The temperature that above-mentioned electric heater is set from the said temperature setting device is lowered the temperature in required time, and then returns to the cooling timing circuit of design temperature.

According to the present invention, when health is felt to feel cold or adstante febre,, then heat up or the cooling state keeps just can returning to normal temperature after the regular hour if connect intensification timing circuit or cooling timing circuit as required.So the user need not wait until that health feels warm or nice and coolly just can fall asleep, and uses very convenient.

In an embodiment, controller heats up or the button of cooling switch can be done more greatly, as long as and to click button just passable.So, need not see that the literal of knob operates with sleepy eyes, particularly the people of eyes presbyopic can remove from and wear the trouble that presbyopic glasses is watched literal on the knob, and needn't not see owing to eyes, has estimated operation knob with regard to the sensation that only relies on finger tip.

In addition, both having made is normal people, also need not be intended to make the knob of controller to point to the operation of higher or lower temperature according to the temperature on the same day, point at knob on the situation of normal temperature, press as required and heat up or the cooling switch, just can raise in the temperature of heater for sleeping or reduce under the state of a period of time and fall asleep.As mentioned above, utilize the present invention can be operated, easy and be easy to reach the heater for sleeping of the comfortable purpose of sleep.

31 is power supply, and 32,33,34 is resistance, the 35th, and with the temperature adjustment variable resistor of 2 interlocks of knob among Fig. 1.48 is the temperature-sensitive electric heater, its structure is well-known, is wound with heating wire 37 around the heart yearn, covers the temperature sensor (plastics thermistor) 38 with negative impedance temperature characterisitic above, wind with holding wire 36 outside again, and pattern in accordance with regulations is contained on the electric mattress then.39 are the pulse producing component, and 40 is pulse transformer, and 41 is thyristor.42 are the change over switch of intensification timing circuit 46, if click button 3, then temporarily connect change over switch 42, make 46 startings of intensification timing circuit, the contact 47 of intensification switch disconnects the regular hour, and the temperature of temperature-sensitive electric heater is risen, and the temperature of electric mattress also increases.43 change over switches for cooling timing circuit 44, if press button 4,43 temporary transient connections of change over switch, make 44 startings of cooling timing circuit, the contact 45 of cooling switch is connected the regular hour, and the temperature of temperature-sensitive electric heater 48 is descended, and the temperature of electric mattress decreases.The effect of control circuit is, when change over switch 42,43 was not worked, supply voltage was by the series circuit dividing potential drop of resistance 32,33,34, and the voltage on the resistance 32 is reduced to the X volt, (is assumed to A with the voltage of the low X volt of supply voltage ₁Volt) A ₁Volt, the impedance by variable resistor 35 and temperature sensor 38 is dividing potential drop once more, and this voltage is added on the pulse producing component 39 that is connected between holding wire 36 and the heating wire 37.During low temperature, the impedance of temperature sensor is higher, so, voltage between holding wire 36 and the heating wire 37 is also higher, makes 39 conductings of pulse producing component, therefore, the pulse signal is added to the control utmost point of thyristor 41 by pulse transformer 40, make thyristor 41 conductings, so heating wire 37 heatings, the temperature of temperature-sensitive electric heater 48 rises.If the temperature of temperature-sensitive electric heater 48 raises, the impedance of temperature sensor 38 then descends, and its voltage drop reduces, therefore pulse producing component 39 not conductings, thyristor 41 also remains on nonconducting state, so heating wire 37 stops heating, the temperature of thermal heater 48 descends.Repeat aforesaid operations, just can be transferred to according to the determined temperature of the resistance of variable resistor 35.This illustrates heating wire 37 and temperature sensor 38 structure as one, when heating wire 37 and temperature sensor 38 adopt other kind structural shapes, also can carry out same temperature control.

Secondly, the change over switch 42 of intensification timing circuit 46 is once connection, intensification timing circuit 46 is just reset, and the contact 47 of intensification switch is remained on open-circuit condition according to time with timing setting in advance, set resistance 33 that the circuit of variable resistor 35 is connected in parallel and 34 series circuit thereby disconnect with temperature.Because above-mentioned A ₁Only rise X volt of volt voltage, so impedance step-down (high temperature side) at temperature sensor 38, its impedance decrement and X lie prostrate when suitable, the voltage of temperature sensor makes pulse producing component 39 stop conductings, and stop to the temperature-sensitive heating installation power supply, therefore, can be transferred to the high temperature suitable to the temperature of electric mattress with above-mentioned decrement.If change over switch 43 closures of cooling switch, the cooling timing circuit just recloses, and the contact 45 of cooling switch is according to predefined time closure, so, in this section resistance 34 short circuits in the time, set the resistance value that the circuit of variable resistor 35 is connected in parallel with temperature and reduce, therefore, above-mentioned A ₁Just in time descend y volt of volt voltage, it equals the voltage drop of resistance 34, and opposite when closed with the change over switch 42 of above-mentioned intensification switch, the temperature of control electric mattress makes it the numerical value that keeps lower.For change over switch 42 or 43, click button 3 or 4, contact is just closed; If the relieving knob, contact just disconnects.

When intensification switch person lowers the temperature switch work, the excursion that heats up or lower the temperature is preferably elected 2 ℃-6 ℃ as, this be because, for the people in the quilt, the scope of comfort temperature narrow (32 ℃～35 ℃), if depart from this scope, will feel sultry or cold, so need not strengthen excursion.Therefore, strengthen range of temperature in short-term, for example, when making temperature short time after the intensification identical with the high temperature scale value, perhaps the temperature value after the cooling is low to below 20 ℃ the time, perhaps because of timer breaks down can not return to original temperature the time, will feel tangible discomfort; The situation of feeling cold or generating heat when health felt that cold or overheated degree was just more obvious more after a little while.
