Description

Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a heating curtain that has a curtain body and a heater and performs heating by dissipating heat from the curtain body.

(Prior art) Generally, inside openings such as windows indoors, light shielding and
Curtains are installed for purposes such as cold protection and decoration, but in recent years, various heating curtains have been proposed in which linear or planar heaters are attached to the entire surface or interior of the curtain body. Development is underway.

Although heating curtains like this improve the insulation effect of wall materials, they also locally heat openings such as windows, which are relatively weak points in terms of insulation, and prevent cold air from entering between them. In addition to having the function of heating the room at the same time, it also has the advantage of eliminating the need for a dedicated space for arranging heating equipment. Space-saving heating curtains based on such multiple functions are extremely promising as fixtures for indoor spaces in recent years, where various fixtures are arranged in a limited space, and further development is expected.

In addition, with the recent diversification of lifestyles, the decorative nature of indoor fixtures has become particularly important, and curtains are also placed not only inside openings, but also on the inside of walls, or as partitions between indoor spaces. Its use for various purposes is expanding. On the other hand, with this tendency to emphasize decorativeness, curtains with a wide variety of designs have become popular, and in particular, curtains of a type that have increased decorativeness due to the opening/closing structure of the curtain body are attracting attention.

For example, the recent spread of so-called Roman shade style curtains, in which the curtain body is rolled up, and roll style curtains, in which the curtain body is rolled up,
Demand for roll-type curtains, which can be installed anywhere, are easy to handle, and have excellent decorative properties, is increasing rapidly.

(Problems to be Solved by the Invention) By the way, when a heater is attached to a roll-type curtain, the following drawbacks occur. That is,
If the operator accidentally starts winding the curtain body while the heater is still energized, the density of the heater will become extremely high due to the heat generated by the energization, and the curtain body will overheat, which can be dangerous. be.

Note that this drawback is not limited to roll-type curtains, but also Roman shade-type curtains in which the curtain body is rolled up in one direction, curtains in which the curtain body is folded horizontally multiple times, etc. Curtains with various storage structures generally exist.

Furthermore, even in curtains that do not have a storage structure, abnormal overheating may occur for some reason.

The present invention was proposed in order to solve the following two problems of the prior art, and its purpose is to provide a highly safe and excellent solution that can quickly and reliably eliminate abnormal overheating. The purpose is to provide heated curtains.

In particular, when a heater is attached to a roll-type curtain, the objective is to improve safety by preventing the curtain body from overheating even if winding is accidentally started without turning off the power. There is one.

Furthermore, as with general heating equipment, one of the purposes is to improve heating efficiency.

[Structure of the Invention] (Means for Solving the Problems) A heating curtain according to the present invention has a heating power tens that includes a curtain body and a heater that is disposed on or inside the curtain body and generates heat when energized. It is characterized by having temperature sensors arranged at a plurality of locations on the main body, and a control circuit that controls energization of the heater based on the temperatures detected by the plurality of temperature sensors or the temperature difference thereof.

Further, in a roll-type curtain that is rolled up with the upper end of the curtain body as the center of winding, it is desirable to arrange temperature sensors at the upper and lower parts of the curtain body, respectively.

Furthermore, a high-emission material layer with high far-infrared radiation efficiency is provided on the side of the space to be heated in the curtain body, and a heat insulating material layer is provided on the opposite side, and a heater is placed between these high-emission material layers and the heat insulating material layer. This is desirable.

(Function) In the heating curtain of the present invention having the above-described configuration, the temperature sensor detects the temperature at multiple locations of the curtain body instead of the heater, and the control circuit detects the temperature based on the detected temperature or the temperature difference. Since the energization of the heater can be controlled, abnormal overheating of the curtain body can be quickly and reliably detected and the energization of the heater can be stopped.

Specifically, in a roll-type curtain that is rolled up with the upper end of the curtain body as the center of winding, if temperature sensors are placed at a part and a lower part of the curtain body, the operator may accidentally If the curtain body is rolled up while the heater is still energized, the heater density at the center of the winding becomes high and the temperature becomes high at the center of the winding. There is a difference in the detected temperature between the temperature sensor placed at the top of the curtain body and the temperature sensor placed at the bottom of the curtain body, which is located on the outer periphery of the winding or is still in the unfolded state. Based on this temperature difference, control is performed. The circuit can quickly cut off the current. Therefore, the current supply can be reliably interrupted at an early stage before overheating of the center of the winding progresses.

Furthermore, if a high-emission material layer and a heat-insulating material layer are provided on both sides of the curtain body, and a heater is placed between them, the far-infrared rays emitted from the heater will be efficiently radiated into the space to be heated by the high-emission material layer. At the same time, the insulation layer can prevent heat radiation to the space on the opposite side, which is not to be heated, so the radiation from the heater can be effectively used.
Highly efficient heating can be performed.

(Embodiment) An embodiment in which the heating curtain according to the present invention is applied to a roll-type curtain will be specifically described below with reference to FIGS. 1 to 4.

First, FIG. 1 is a perspective view showing the entire heating curtain.

As shown in FIG. 1, the curtain body 1 is attached at its upper end to a rotating rod (winding core) 3 rotatably fixed to a support bracket 2, and is wound by rotating the rotating rod 3 in one direction. ”It's starting to get worse. This rotating rod 3 is urged in the winding direction by an elastic member (not shown), and is fixed by a locking device (also not shown) when no external force is applied.

On the other hand, a support member 4 is attached to the lower part of the curtain body 1, and a puller 5 is attached to the center of the support member 4. By pulling down the puller 5 with a predetermined force or more, the above-mentioned lock is activated. When it comes off, the curtain body 1 is pulled down and unfolded, and when the puller 5 stops being pulled down (with more than a predetermined force), the locking device operates and the curtain body 1 is fixed in that state. It is now possible to do so.

Furthermore, if the puller 5 is released immediately after the locking device is released by pulling down the puller 5 slightly, the rotating rod 3 will rotate in the winding direction due to the biasing force of the elastic member, and the curtain body 1 will be rolled up. It has become.

Further, a connector 6 is provided at the lower right end of the curtain body 1, and is connected to a connector 8 provided at one end of a power cord 7. Among these, the connector 6 of the curtain body 1 is connected to the heater 13 (FIG. 2) and the signal line 14, 15 (FIG. 2) built into the curtain body 1, and the connector 8 of the power cord 7 is It is connected to a power supply conductor (not shown) and a signal line (not shown) built into the power cord 7, and these connectors 6.
By the connection 8, the heater 13 and the power supply conductor wire of the power cord 7 are connected, and the signal wire of the curtain body 1 and the signal wire of the power cord 7 are connected, thereby forming a signal transmission path. It looks like this. Note that the other end of the power cord 7 is provided with a power plug 9 that is connected to an AC power source.

A controller 10 is provided in the middle of the power cord 7, and an upper temperature sensor 11 and a lower temperature sensor 12 are provided at the upper end of the curtain body 1, which is the center end of the winding, and the lower end, which is the outer peripheral end of the winding. is established,”-

A detection signal is sent to the controller 10 via a signal transmission path formed by the connection of the two. This controller 10 includes an arithmetic circuit 2, as described later.
2 (FIG. 4), a control circuit 23 (FIG. 4), and a cutoff switch 24 (FIG. 4).

Next, FIG. 2 is a front perspective view showing the arrangement pattern of the heater 13 with respect to the curtain body 1. As shown in FIG.

As shown in FIG. 2, the heaters 13 are arranged so that their horizontally long parts are lined up in multiple stages below the winding center. The arrangement density is higher at the lower part of the curtain body 1 on the supinated circumference side. In addition, the curtain body 1
In consideration of windability, a portion where the heater 13 is not placed is provided at the two end portions. Both ends of the heater 13 arranged in this way are connected to a connector 6 provided at the lower right end of the curtain body 1, and via this connector 6, a power cord is connected as shown in FIG. 7, and power is supplied from an external power supply.

Further, as shown in FIG. 2, the two-part temperature sensor 11 and the lower temperature sensor 12 are arranged at a predetermined distance from the heater 13, and the signal lines 14.
15 to the connector 6. As described above, these signal lines 14.15 are connected to the corresponding signal lines of the power cord 7 shown in FIG. 1 via the connectors 6.8 to form a signal transmission path. There is.

Next, FIG. 3 is an enlarged sectional view of the curtain body 1, and shows the surface side of the curtain body 1, that is, the space S to be heated.
On the 1 side, a curtain fabric 16 and a far-infrared high-emission fabric (high-emission material layer) 17 with high far-infrared radiation efficiency are placed one on top of the other on the front and back sides, and the back side of the curtain body 1, that is,
Highly insulating felt (insulating material layer) 18 is placed on the heating target space 1 and S2 side.
is arranged, and on the surface of this felt 18, an aluminum foil 1 is placed.
9 and lining 20 are sequentially overlapped. and,
A heater 1 is placed between the far-infrared high radiation cloth 17 and the felt 18.
3 is placed. This heater 13 is a known linear heater made of copper wire coated with vinyl chloride. Note that these components of the curtain body 1, namely, the curtain fabric 16, the far-infrared high radiation cloth 17, and the felt 18
, aluminum foil 19, lining 20, and heater 13 are bonded together.

Furthermore, FIG. 4 is a block diagram showing a heater control configuration based on temperature detection.

That is, as shown in this FIG. has been done. The calculation circuit 22 calculates the temperature difference between the detection signals from the upper and lower temperature sensors 11 and 12, and sends the calculation result (detected temperature difference) to the control circuit 23. The control circuit 23 has a fixed reference temperature difference set in advance, and compares this reference temperature difference with the obtained detected temperature difference. If the detected temperature difference is less than the reference temperature difference, the cutoff switch 24 is activated. without operating
The power supply to the heater 13 is continued, and if the detected temperature difference exceeds the reference temperature difference, the cutoff switch 24 is operated to cut off the power supply to the heater 13.

The operation of this embodiment having the configuration as shown below is as follows.

First, during heating, as shown in FIGS. 1 and 2, the curtain body 1 is fully unfolded, and the connector 8 of the power cord 7 is connected to the connector 6 as shown in FIG. At the same time, by connecting the power plug 9 of the power cord 7 to an AC power source, the heater 13 is energized and starts generating heat.

The heat generated by the heater 13 radiates heat from the curtain body 1, warming the surrounding space.

In this case, in particular, in this embodiment, as shown in FIG. 2, the arrangement density of the heaters 13 below the curtain body 1- is high, so that heat convection is generated by heating the lower part of the room intensively. It is possible to equalize the indoor temperature by generating heat, which is comfortable for the body and also improves heating efficiency.
- also leads to.

In addition, in this embodiment, as shown in FIG. 3, far-infrared high radiation cloth 17 and felt 18 are provided on both sides of the curtain body 1, and the heater 13 is placed between them, so that the radiation from the heater 13 is removed. The far infrared rays can be efficiently radiated to the heating target space S1 by the far infrared high radiation cloth 17, and the highly insulating felt 18 can prevent heat radiation to the non-heating target space S2 which is not to be heated. Therefore, by effectively utilizing the radiation from the heater 13,
It has the advantage of being able to improve heating efficiency.

Furthermore, in this embodiment, since one aluminum foil is provided on the surface of the fers l-1 and 8, far-infrared radiation transmitted through the foot 19 can be reflected toward the space S1 to be heated by this aluminum foil 19. Therefore, the effect of preventing heat radiation to the non-heating target space S2 is further improved.

Note that during such heating, the lower temperature sensors 11 and 12 are in a temperature detection state, and transmit detection signals to the arithmetic circuit 22 continuously or intermittently. In this case, the detected temperature difference calculated by the arithmetic circuit 22 is
If the control circuit 23 determines that the temperature difference is below the reference temperature difference, the control circuit 23 continues supplying power to the heater 13 without operating the cutoff switch 24.

On the other hand, if the control circuit 23 determines that the detected temperature difference calculated by the arithmetic circuit 22 exceeds the reference temperature difference, that is, the temperature difference is determined to be due to an inconvenience such as excessive heater heat generation or abnormal overheating due to other causes. ,'' If the temperature detected by the two-part temperature sensor 11 is higher than the temperature detected by the lower temperature sensor 12 by more than the reference temperature difference (or vice versa), the control circuit 23 operates the cut-off switch 24. Then, the power supply to the heater 13 is stopped. Therefore, in the event of an inconvenience such as abnormal overheating of the curtain body 1, the heater 13
It can stop the heat generation and has excellent safety.

On the other hand, when unwinding the curtain body 1 in the non-heating state, disconnect the power cord 7, pull down the pull handle 5 slightly to release the locking device (not shown) on the rotating rod 3, and then pull it immediately. If you let go of hand 5, the rotating rod 3 will
The curtain main body 1 is rotated in the unwinding direction by the biasing force of an elastic part (not shown), and the curtain body 1 is unrolled.

By the way, the operator forgot to disconnect the power cord 7 and performed the winding operation as described above with the power cord 7 still connected, that is, with the heater 13 still generating heat. In this case, since the heaters 13 are concentrated at the center of the winding, the space between the windings becomes overheated. In this case, the temperature detected by the two-part temperature sensor 11 installed at the upper end of the curtain body 1, which is the central part of the winding, is at the outer periphery of the winding or at the bottom of the curtain body which is still in the unfolded state. The temperature increases over time with respect to the temperature detected by the lower temperature sensor 12 arranged therein. Then, based on the detection signals sent from each temperature sensor 11 and 12, the calculation circuit
When the control circuit 23 determines that the detected temperature difference calculated in step 2 exceeds the reference temperature difference, the control circuit 2
3 operates the cut-off switch 24 to stop supplying electricity to the heater 13. Therefore, the power supply to the heater 13 can be reliably cut off at an early stage before overheating of the center of the winding progresses, resulting in excellent safety.

In addition, when unfolding the tension tension curtain main body 1 which has been removed from the winding 11 by the second winding operation, if the puller 5 is pulled down by a predetermined amount of force, the lock will be released and the curtain main body 1 will be opened again. is lowered. Then, when the pulldown is stopped at a desired location, the locking device operates and the tension tension main body 1 is fixed in the desired deployed state.

Furthermore, such a state where the curtain body 1 is in the middle of being unfolded,
That is, even if the operator accidentally connects the power cord 7 and attempts to start heating while a part of the curtain body 1 is wound around the rotating rod 3, the operation will be interrupted in the same way as when starting the winding.
The control circuit 23 quickly determines whether the center of the winding is overheated, and the cutoff switch 24 shuts off the power to the heater 13. Electricity can be cut off reliably.

In the above embodiment, the control circuit 23 was operated based only on the difference between the temperatures detected by the detection sensors 11 and 12, but an arbitrary control temperature is further set in the control circuit 23, and this control temperature and Of course, it is also possible to add a configuration in which temperature control is performed by comparing each detected temperature individually.

Furthermore, the present invention is not limited to the above embodiments,
It can be similarly applied to curtains with various storage structures other than the roll type, for example, it can be applied to Roman shade type curtains or curtains with a structure that can be folded multiple times in the horizontal direction. The number and location of the temperature sensors to be provided can be selected as appropriate, but the temperature sensors are installed at least on the inner surface of the folding start end where the heater is concentrated due to folding, the outer surface of the final folding end, or the outer surface portion that is not folded. It is desirable to place them in both.

Furthermore, the present invention is equally applicable to curtains that do not have a storage structure.

Similarly, the control configuration on the control circuit side can be freely selected, and various fixed or variable reference temperatures or reference temperature differences can be set, and multiple detected temperature data can be used to turn on/off the energization. It is possible to freely select and use the means or means for switching the amount of current.

In addition, the temperature sensor and control circuit of the present invention can be used not only for current interruption in the event of abnormal overheating, but also for normal temperature control. By setting the reference temperature value,
It enables fine-grained temperature control and contributes to the realization of comfortable indoor heating.

On the other hand, the specific materials of the heater and each component of the curtain body can be selected as appropriate; for example, the heat insulating material is not limited to felt.

[Effects of the Invention] As explained above, in the present invention, abnormal overheating of the curtain body can be prevented by arranging temperature sensors at multiple locations on the curtain body and providing a control circuit for controlling the energization of the heater. It is detected by multiple temperature sensors and the control circuit can cut off the power to the heater, so abnormal overheating of the curtain body can be quickly and reliably resolved.
It is possible to provide a highly safe and excellent heating curtain.

In particular, in roll-type curtains, temperature sensors are
If they are placed at the top and bottom of the curtain body, even if you accidentally start winding without turning off the power, the control circuit can immediately cut off the power to the heaters based on the temperature difference. can prevent overheating.

Furthermore, if a high-emission material layer and a heat-insulating material layer are provided on both sides of the curtain body, and a heater is placed between them, the far-infrared rays emitted from the heater will be efficiently radiated into the space to be heated by the high-emission material layer. At the same time, the insulation layer can prevent heat radiation to the space on the opposite side, which is not to be heated, so the radiation from the heater can be effectively used.
It can greatly contribute to improving heating efficiency.

The configuration including the temperature sensor and control circuit of the present invention can be used not only for current interruption in the event of abnormal overheating, but also for normal temperature control, and the location of the temperature sensor can be freely set. By setting various reference temperature values, it is possible to perform fine-grained temperature control, contributing to the realization of comfortable indoor heating.
