Description

TECHNICAL FIELD The present invention relates to a method for killing harmful microorganisms such as mites attached to an electric heating cloth.

[Conventional technology]

A conventional electric heating cloth will be described with reference to FIGS. 7 to 9.

In the figure, (1) is an electric blanket that is a heating cloth, and is composed of a blanket (2) and a heat generating device (3) drawn inside the blanket (2) in a comb-like shape. As shown in FIG. 9, the heat generating device (3) has a heating wire (3
b), the outer circumference of which is coated with a heat-sensitive layer (3c) having negative resistance temperature characteristics, the outer circumference of which is wrapped with a signal wire (3d), and the outer circumference of which is covered with an outer skin (3e). ing. Reference numeral (4) is a temperature control device for controlling the heat generating device (3) and is connected to the electric blanket (1) via a cord (5) which is detachably connected. (6) is a power cord connected to the temperature control device (4). Next, the circuit configuration of the electric heating cloth will be described with reference to FIG. In the figure, (7) is a capacitor, (8) is a thyristor (semiconductor switching element), (9) is a protection resistor for this thyristor (8), (10) is a semiconductor ignition element for operating the thyristor (8), (11) is the temperature control volume, (1
2) and 13) are current limiting resistors, 14 is a power switch, and 15 is an AC power supply. The temperature control device (4)
Is a general term from (7) to (14).

Next, the operation will be described. First, the electric blanket (1) is hung on the quilt, the quilt is hung on the quilt, and then the warmer enters between the quilt and the electric blanket (1) and lays down. When the warmer turns on the power switch (14), the current flows from the power switch (14) to the temperature adjusting volume (11) current limiting resistors (12), (13), signal line (3d), capacitor. (7), flows to the heating wire (3b) and charges the capacitor (7). When the charging voltage of the capacitor (7) reaches the ignition voltage of the semiconductor ignition element (10), the charge charged in the capacitor (7) passes through the semiconductor ignition element (10) and the thyristor (8) is charged. By flowing from G (gate) to K (cathode), the thyristor (8) is turned on between A (anode) and K (cathode). As a result, the main current (heating line current) flows from the power switch (14) to the heating line (3b) through A (anode) and K (cathode) of the thyristor (8). This operation is repeated for the number of frequencies of the AC power supply (15), and the temperature of the heating wire (3b) starts to rise. As the temperature of the heating wire (3b) rises, the temperature of the heat sensitive layer (3c) also rises, and its resistance value becomes smaller as the temperature rises because it has a negative resistance temperature characteristic. When the resistance value of the heat sensitive layer (3c) becomes small, the charging current to the capacitor (7) does not pass through the capacitor (7) but goes from the signal line (3d) to the heat sensitive layer (3cf) and the heating line (3b).
It flows to the bypass circuit leading to. When the current to the bypass circuit increases and the charging current of the capacitor (7) becomes lower than the ignition voltage of the semiconductor ignition device (10), the semiconductor ignition device (10) is turned off. ) Discharge current does not flow to G (gate) of the thyristor (8). As a result, the A (anode) and K (cathode) of the thyristor (8) are turned off, and the main current does not flow to the heating wire (3b). When the main current stops flowing to the heating wire (3b), the heating wire (3b) stops its heat generation, and the temperature of the heat sensitive layer (3c) gradually drops. As the temperature drops, the resistance value of the heat sensitive layer (3c) gradually increases, and the bypass current flowing through the heat sensitive layer (3c) decreases. As a result, the condenser (7)
A large amount of charging current flows to, and the charging voltage rises. When this charging voltage rises to the ignition voltage of the semiconductor ignition element (10), the semiconductor ignition element (10) is turned on and the charge is transferred from G (gate) to K (cathode) of the thyristor (8). The thyristor (8) flows to turn on between the A (anode) and K (cathode) of the thyristor (8). The main current flows between the A (anode) and K (cathode) in the ON state and flows to the heating wire (3b). By repeating the above, the temperature is kept constant.

When the resistance value of the temperature adjusting volume (9) is set small, a high voltage is applied to the capacitor (7). Therefore, the charging voltage does not become lower than the ignition voltage of the semiconductor ignition element (10) unless the resistance value of the heat sensitive layer (3c) becomes extremely small. This results in a high temperature setting. On the contrary, when the resistance value is set large, a low voltage is applied to the capacitor (7), and the resistance value of the thermosensitive layer (3c) becomes the firing voltage or less even if the resistance value is not so small, and the temperature is set low. The temperature control range is the temperature control volume (9).
The surface temperature of the electric blanket (1) can be changed to 20 ℃
Adjusted to ~ 50 ° C.

[Problems to be Solved by the Invention]

Since the conventional electric heating cloth is configured as described above, in order to kill harmful microorganisms such as mites that live in the electric blanket (1) and cause allergic diseases such as dermatitis and bronchial asthma to the heat collector. Was going to be sun-dried. However, sun-drying has problems that it takes time and effort to put out an electric blanket (1) outdoors, and there are cases where the sun-drying becomes impossible due to the building environment, the weather, etc. There was a problem that mites could not be killed only by sun-drying because they were evacuated to the backside where the sun was not exposed during sun-drying. As a solution to this problem, as disclosed in JP-A-62-77525, the electric blanket (1) has a heating element so that the temperature and time for killing harmful microorganisms such as mites higher than the normal heating temperature can be satisfied. There is also a method of controlling the temperature, but with such a method, if a warmer mistakenly collects heat at this high temperature, there is a risk of causing injury such as burns. Moreover, even if the electric blanket (1) is at a high temperature, harmful microorganisms such as mites are still converted from the electric blanket (1) to the electric blanket (1).
When the electric blanket (1) is evacuated from the surface on which the is placed and then returns to the normal temperature, the electric blanket (1) will enter the electric blanket (1) again, so sufficient mites and other killing will not occur. I couldn't do it. However, there is a problem in that the conventional method used for the reason is dangerous and incomplete.

Regarding the temperature of killing mites, see, for example, Japanese Patent Laid-Open No. 62-
127026 has been introduced in many documents such as "Ticks die in 2-3 minutes at a temperature of 50 ° C. or higher".

The present invention has been made to solve the above problems, and an object thereof is to obtain a method for killing harmful microorganisms such as mites of an electric heating cloth, which can safely and reliably kill harmful microorganisms such as mites.

With heat resistance to withstand
Equipped with a storage device that does not allow passage of harmful microorganisms such as mites or that does not easily pass through it, folds and stores the heating cloth inside the storage device, and arranges the temperature control device outside the storage device to cover most or all of the heating cloth. The heating device is switched and controlled so that harmful microorganisms such as mites are killed.

Further, the storage device is provided with a hooking portion that can be hooked on a wall or the like.

Further, the storage device includes an opening provided at a position different from the hooking portion.

Further, the storage device is provided with a sealing means for sealing the opening.

 Further, the storage device has a heating element.

[Action]

In the method for killing harmful microorganisms such as mites of the electric heating cloth according to the present invention, heating for killing harmful microorganisms such as mites is performed after the heating cloth is stored in the storage device, so that harmful microorganisms such as mites do not escape. It can be seen at a glance that it can be surely killed and that it is in a non-heating state.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

In the figure, (1) to (11) and (13) to (15) are almost the same as the above-mentioned conventional apparatus shown in FIGS. (16) is two contact points,
It is a switch having a (16a) side (used during normal heating) and a (16b) side (used during tick mitigation function), and is provided in the temperature control device (4). (17) is the contact (18a), (18
b) and a motor (19), the contact (18a) is provided between the (16a) side contact and the temperature adjustment volume (11), and the contact (18b) is for current limiting. It is provided between the resistors (12) and (13). These contacts (18a) and (18b) are connected to the (16b) side contact and the motor (1
9) is connected in parallel with. (20) is a storage bag as a storage device made of transparent polyethylene, which has heat resistance to withstand the heat generated by the heat generating device (3) and has a length of 40 m.
It has a rectangular shape of m and width 50 mm. This storage bag (2
Since 0) is made of polyethylene, it does not pass ticks, but if the smallest size of ticks is about 1 micron, if it has a fineness of about 1 micron, it does not pass ticks. It can be said that they are doing.

(21) is a fastener provided on one side of the short side of the storage bag (20).

Next, the operation will be described. First, fold the electric blanket (1) into about eight pieces, and then from the fastener (21) to the storage bag (2
When it is loaded in (0), the storage bag (20) fits snugly with the electric blanket (1) inserted. At this time, the cord (5) is left connected to the electric blanket (1). As shown in FIG. 3, the electric blanket (1) is stored and then the fastener (21) is closed, and the power cord (6) is closed. When the switch (16) is switched to the (16b) side, the motor (19) operates and the contact (18a)
And (18b) are turned on. As a result, the temperature control volume (11) and the resistor (12) are short-circuited, and the capacitor (7) is set at a higher temperature than the normal temperature control volume (11) (resistance value 0). A high voltage can be applied and the temperature is set high. This setting value is usually set to 55 ° C while the temperature adjustment range during warming is 20 ° C to 50 ° C.

 Here, the reason why the high temperature setting is set to 55 ° C. will be described.

As mentioned above, mites die at 50 ° C in a few seconds, but it can be seen that the wiring of the heating wire (3b) is relatively rough in the case of an electric blanket, as shown in Fig. 1. Therefore, in order to make the corners of the blanket (2) farthest from the heating wire (3b) to 50 ° C to kill the mites, there is a heat loss when the heating wire (3b) itself is 50 ° C. The reason is that it does not reach 50 ℃. If the exothermic line (3b) is about 55 ° C, which is somewhat higher than the temperature, the corner can reach 50 ° C even if there is heat loss. However, electric carpets, etc.
If the heating wire wiring is relatively dense, even if the high temperature setting temperature is set to 50 ° C, 52 ° C, 53 ° C, etc., and the heating wire (3b) is heated at that temperature, that temperature is transmitted to the corners. Is.

The heating wire (3b) is energized by the contact (16) of the switch (16).
It flows from b) through the contact (18a) of the timer (17) and A (anode) and K (cathode) of the thyristor (8). After the rising temperature rise time has passed, the heating wire (3b)
At 55 ° C, the temperature is continued so that the heat reaches the end of the blanket (2) (heat conduction time). Then, when the heat spreads over the entire blanket (2), it is operated for a time (for example, 10 seconds) until the killing of the mites is completed by the heat (a predetermined time). The heat conduction time depends on the material and shape of the blanket (2), the heat distribution state of the heating wire (3b), and the like. Contact (17a) of the timer (17) after a predetermined time
And (17b) are opened and the power supply to the heating wire (3b) is stopped. As a result, the rising temperature rise time, heat conduction time,
And the tick elimination operation for a predetermined time is completed.

As described above, the electric blanket (1) may be taken out from the storage bag (20) after the mite elimination operation is completed, and the dead bodies of harmful microorganisms such as mites may be sucked and removed by an electric vacuum cleaner or the like. Also, mites that have escaped into the storage bag (20) may be similarly removed by suction with an electric vacuum cleaner.

As described above, since the electric blanket (1) is stored in the storage bag (20) and then the high temperature operation for eliminating the mites is performed, the mites in the electric blanket (1) are stored in the storage bag (20). ) Is impermeable to ticks, it is difficult to escape from here and can be surely killed. Also, by putting it in the storage bag (20), the user and the third party can know that it is in a non-heat collecting state. Therefore, a warning is given to prevent the electric blanket (1) from being mistakenly used during high temperature operation. Play a role. In addition, since the heat radiation of the heating wire (3b) is suppressed by putting it in the storage bag (20), it is possible to more effectively kill mites and the like. Further, in the above embodiment, the timer (17) is used to limit the functioning time for eliminating ticks, but it may be a reset type thermostat, an electronic circuit with a temperature sensor, or another switch.

Further, in the above embodiment, the rectangular storage bag (20) was used as the storage device, but the shape is not limited to this, and for example,
It may be circular, square, triangular, or box-shaped, and the shape is not limited to this.

Further, in the above embodiment, the accommodating device is made impermeable to mites, but is made impermeable to mites and has a small hole or the like in a part of the accommodating bag (20) or is large in size with a diameter of more than 1 micron. Fineness of the eyes that mites cannot escape, eg 5
Most mites, even those of the micron size, are effective because they can kill most mites.

Further, in the above-mentioned embodiment, the transparent storage bag (20) made of polyethylene was used as the storage device, but other materials such as synthetic resin, synthetic fiber, metal, non-metal, wood, paper, glass,
Any of ceramics, minerals, etc. that are impermeable or difficult to pass and have a heat resistant temperature that can withstand the heat generation of the heat generating device (3) may be used, and the same effects as the above effects can be obtained. In addition, if the storage device is non-breathable and a deodorant is provided to eliminate the bad odors and odors such as sweat generated during the tick elimination operation, the double effect of eliminating and deodorizing ticks can be achieved. I can.

If the storage device is provided with a drug for bag mites (eg, Fundantide) impregnated, a more reliable killing of mites can be achieved by the synergistic effect of high temperature and drug. Further, if a ring (22) as shown in FIG. 4 is provided at the corner of the storage device, it can be hung on the wall for mite elimination operation. By doing so, the rising heat of the heating wire (3b) further heats the upper blanket (2) portion, so that the heat radiation can be used more effectively and it can be hung in a high place where infants cannot reach. It can be lowered to protect infants from the risk of burns. Also, since it is hung at the corners, the weight of the blanket (2) can be received by the lower two sides, and it is difficult to bend. In addition, if you print a message such as "The electric blanket is stored in this bag and the temperature is high during tick elimination while the electricity is on, please do not use it." Become more certain. In addition, a thermometer may be provided in the storage device to notify that the temperature is high.
Also, an electric blanket (1) and a temperature control device (4) are installed in the storage device.
It is convenient to store and when you don't use it in summer. Also, if a heat insulating material is applied to the storage device, the heat radiation of the heating wire (3b) can be prevented. Further, as shown in FIG. 5, if a heating element (23) is wired in the storage device itself and connected to the temperature control device (4) to heat from the inside and outside of the electric blanket (1), more reliable mites can be obtained. Can be killed. Further, the wiring of the heating element (23) is made orthogonal to the heating wire (3b) laid on the electric blanket (1), and if the wiring of the heating element (23) is a mesh-like wiring, the blanket (2) There is an effect that the heating is uniform.

Further, since the heating element (23) is arranged in the storage bag (20) itself, the temperature control device (4) and the power cord (6) are attached to this.
If it is provided so that it can be connected independently, it will become an electric storage bag, and you can store the desired one in this and warm it. For example, put underwear for tomorrow's clothes in this and go to bed. The next morning, the timer (17) provided in the temperature control device (4) turned on the heat generation circuit from 5 o'clock, and the warm underwear was completed at 6 o'clock when waking up. Therefore, it has the effect of being very convenient and comfortable especially on cold mornings in winter.

When the mite extermination operation is performed by the heat generator (3) of the electric blanket (1) and the heat generator (23) of the storage bag (20), the temperature of the heat generator (3) and the heat generator (23) are controlled. If it is not connected to the device (4), the circuit configuration is such that the mite extermination operation cannot be performed, and the structure is such that the mite extermination operation can be performed only when the electric blanket (1) is stored in the storage device. In this way, it is possible to prevent ticks from being mistakenly driven when collecting heat, resulting in excellent safety. A magnetic material such as a magnet is provided in the storage device, and a detection device is provided in the electric blanket (1) to detect that the electric blanket (1) is stored in the storage device, and a circuit for eliminating ticks is set. It may be turned on, and the structure for allowing ticks to be eliminated only in the stored state is not limited to this. Also, if a shock sensor is provided in any of the electric blanket (1), the storage device, and the temperature control means (4), and if they are moved during tick mitigation operation, it will be mistakenly used if provided. It is safe because if you try to do so, the tick elimination drive will end automatically.

Further, as shown in FIG. 6, locking devices (24) such as buttons are provided at four corners of the storage bag (20), and the upper surface of the electric blanket (1) corresponding to the warmer's foot is correspondingly provided. If a device to be locked is provided in the box so that it can be locked when the tick elimination operation is not performed, the storage bag (20) is prevented from being lost, and the storage bag (20) is provided on the foot. This has the effect of improving the heat retention of the feet when collecting heat.

In the above embodiment, the storage bag (20) is attached to the fastener (21).
However, the opening / closing means may be an opening / closing tool in which a resin-made concave portion is provided on one side of the opening end and a resin-made convex portion to be fitted therein is provided on the other side. The opening / closing means is not limited to this. Further, if the opening side of the storage bag (20) is provided so that it can be folded and the folding end is provided between the storage bag (20) and the placing surface, the opening is closed. Therefore, the cost can be reduced without using a special opening / closing tool. Further, in the above-mentioned embodiment, the fastener (21) is provided on one side of the short side of the rectangle, but if it is provided on three sides, the storage bag (20) can be unfolded, and the carcass of the mites can be removed by a vacuum cleaner. Improves cleaning performance when suctioning. In addition, although the electric blanket (1) is folded in eight in the above-mentioned embodiment, the heat generating device (3) of the electric blanket (1) usually corresponds to the foot portion rather than the chest of the warmer. , Since the wiring is dense, when this folding is taken into consideration, if the first fold is made to face the chest and feet, and then the folds are sequentially folded, the electric blanket (1) will generate heat. Are made uniform. Further, in the above embodiment, the electric blanket (1) is folded, but it may be flat without folding or rolled and put in the storage bag (3). In addition, a temperature sensor is provided at the corner of the chest of the electric blanket (1) where the heating is slowest or at the corner of the storage device, and the tick elimination operation is terminated according to the input of this temperature sensor. A reliable tick killing can be performed.

Although the electric blanket (1) was used as the heating cloth in the above embodiment, not only the electric blanket and the electric blanket, but also the electric cushion, the electric cushion, the electric carpet, the electric knee, the electric belly, the electric futon, and the electric blanket. Needless to say, it includes all kinds of warming devices having cloth parts such as electric foot heaters, electric pads, electric seats, electric pants, etc., and the effects are almost the same. Further, the circuit configuration of the temperature control device (4) of the above embodiment is only one implementation and may have other circuit configurations, and the height and time of the set temperature are also the material shape of the heating cloth, the heating wire (3b). According to the wiring condition of
It is arbitrarily set to 50 ° C or higher. Further, in the above-mentioned example, all the mites living in the blanket (2) were killed, but even if most of the blanket (2) was left with the corners / divisions left, it was possible to increase the number of mites to the human body. There is an effect that the adverse effect of can be prevented. In addition, the end of tick elimination operation may be notified by a buzzer chime, a lamp, or the like.

[Effects of the Invention] As described above, according to the present invention, there are the following effects.

Since the heating cloth is folded and stored in the storage device and the temperature control device is arranged outside the storage device, the heat generation effect received from the heating device of the heating cloth is improved, and the ability to kill harmful microorganisms such as mites is improved. Further, since dead bodies of harmful microorganisms such as mites are stored in the bag, they can be sucked by an electric vacuum cleaner or the like and easily removed. Further, for example, a temperature control device equipped with electronic components that are weak in temperature is not heated and is not directly affected by heat from the heat generating device, and precise temperature control can be performed.

Further, since the storage device is provided with the hook portion, the storage device storing the heating cloth can be hooked on a wall or the like, and the storage device does not become an obstacle when killing harmful microorganisms such as mites.

Further, since the opening is provided in the storage device at a position different from the hook portion and the temperature control unit is arranged outside the opening, for example, the power cord provided in the temperature control device is prevented from being heated.

Further, since the sealing means for sealing the opening is provided, harmful microorganisms such as mites are prevented from escaping from the storage device.

Further, since the storage device is provided with the heating element, the heating cloth can generate heat from the heating element and the heating element, and the ability to kill harmful microorganisms such as mites can be improved.
