Description

  The present invention relates to a heating device for bedding used to warm a bedding in a cold state such as winter and secure a comfortable sleeping environment.

  In the cold season such as winter, the bedclothes are in a cold state regardless of whether sleeping in a futon or bed, so it is difficult to sleep until the sleeping space rises above a certain temperature due to body temperature, and bedtime is inevitably shortened Is done. As a means for solving such a poor sleeping environment, it has been common to operate a room-type heating device such as an air conditioner or a warm air heater to heat the entire bedroom. Despite the fact that the sleeping space between the beddings is very narrow, it is possible to obtain a comfortable sleeping temperature by simply carrying out a very narrow local heating. And it is not preferable from the viewpoint of running cost. In addition, if heating is started by heating the heater immediately before going to bed, the thermal energy such as warm air is dispersed throughout the bedroom with a large volume, and the room temperature does not rise uniformly above a certain level so that the bedding is not heated. However, it takes a considerably long time for the bedding itself to reach a comfortable sleeping temperature, and there is a problem that it is not responsive.

  In order to solve the problem of bedding heating means by operating room-type heating appliances such as air conditioners in this way, conventionally, in a tare having air permeability and flexibility such as cloth, it may be crushed by the weight of the sleeping person. Lay a pad containing a hollow structure with sufficient strength (hardness) to ensure no air passage, lay it on the lower bedding such as a futon or mattress, and send warm air into the tare of this pad A bedding heating pad that heats the lower bedding has been proposed (see, for example, Patent Document 1).

  In addition, the hot air generated by the hot air generator built in the main body is inserted between the mattress and the comforter through a hose and fed into a sandwiched mat to dry both comforters. The constructed futon dryer is conventionally known (see, for example, Patent Document 2), and the drying mat in the futon dryer is removed from the hose, the tip of the hose is inserted between the upper and lower bedding, and the warm air is sent to the upper and lower bedding. It was also possible to use a futon dryer to heat the bedding, such as by blowing directly into the sleeping space and heating the sleeping space.

  JP 2004-89660 A   Japanese Patent Laid-Open No. 2002-210297

  Since the methods for heating the bedding using the conventional bedding heating pad proposed in the above-mentioned Patent Document 1 or the conventionally known futon dryer are local heating, a room-type heating appliance such as an air conditioner is used. Compared to the case of using it, there is less heat loss, and energy consumption and running cost can be reduced. However, there are the following inconveniences and disadvantages in actual use. That is, in the former bedding heating pad, warm air is not blown directly into the sleeping space between the upper and lower beddings, but after being blown into the tare containing the hollow structure, the bed is passed through the ventilation portion of the tare. Because it is blown into the space, much of the thermal energy of the hot air is absorbed by the hollow structure, and its energy consumption is less reduced, and it is crushed by the weight of the sleeper Since the hollow structure having a high strength and not disturbing the flow of hot air is housed in the tare, the hollow structure has excellent shape deformation followability. However, it is inevitable that the bedclothes such as futons inherently impair the softness and the drawability of the bedclothes and make the sleeping person feel uncomfortable, and it is difficult to ensure a truly comfortable sleeping environment.

  On the other hand, the method of heating the bedding using the latter futon dryer is capable of blowing hot air directly into the sleeping space, making it possible to use the thermal energy of the hot air most effectively and bedding. While it is possible to make the sleeping environment more comfortable compared to the former without compromising the original softness and drawability, the futon dryer was originally operated continuously for a relatively long time of, for example, 1 hour or more. Therefore, the unit time length for operation control (automatic stop) by a timer provided attached to the futon dryer is as large as about 1 hour, for example. The time interval is set. Therefore, it is very subtle and difficult to set a short driving control time until the sleeping space rises above a certain temperature due to body temperature, and it is easy to vary. There is a practical inconvenience that overheating and heating shortage are likely to be caused due to variations in the temperature. In addition, a large-diameter hose is generally used as a hose for a futon dryer in consideration of drying efficiency. When such a large-diameter hose is inserted between the upper and lower beddings, the hose insertion point is A large gap where the sleeping space communicates with the outside is generated in the part between the upper and lower bedding on both sides of the hose, and the heat escapes from this gap, and it takes a long time to raise the sleeping space to a predetermined temperature. There is a problem that the heat of the sleeping space that has been raised to a predetermined temperature escapes to the outside through the gap, and the sleeping temperature rapidly decreases in a short time.

  The present invention has been made in view of the above-mentioned circumstances, and does not impair the sleeper without any loss of comfort and the sleepiness inherent in the bedding, and can quickly bring the sleeping space to an appropriate temperature without heat loss. An object of the present invention is to provide a heating apparatus for bedding that can be efficiently raised to ensure a truly comfortable sleeping environment and that can reliably hold the comfortable sleeping environment for a necessary length of time.

  In order to achieve the above object, a heating apparatus for bedding according to the present invention includes an apparatus main body having a built-in hot air generation source, one end connected to the hot air outlet of the hot air generation source, and the other end. A heating device for bedding comprising a hot air supply hose which is inserted between the upper and lower beddings and opened to blow warm air into the sleeping space between the upper and lower beddings, When the sleeping space or the upper and lower bedding rises to a set temperature, at least means for automatically stopping the operation of the hot air generating source is provided.

  Here, as means for automatically stopping the operation of the hot air generating source, as described in claim 2, when the temperature sensor arranged in the sleeping space detects a preset temperature in advance, it is transmitted from the temperature sensor. Or a device configured to automatically stop the operation of the hot air generating source upon receiving a detection signal, or the temperature of the sleeping space or the upper and lower beddings rises to a set temperature as described in claim 3 Any of the devices configured to automatically stop the operation of the hot air generation source in response to a timing operation end signal of a timer attached to set the rated operation time length of the hot air generation source necessary for It may be.

  According to the heating apparatus for bedding according to the present invention having the above-described characteristic configuration, the warm air generated by the warm air generation source is blown directly into the sleeping space through the hose. There is no foreign object such as a hollow structure provided in a conventional pad for heating bedding, and the bedding is not only infused with the original softness and drag characteristics of the bedding, but also infused into the sleeper. It is possible to rapidly raise the narrow local area of the sleeping space to the set temperature by making the most effective use of the thermal energy of the warm air. In addition, since it is a heating device dedicated to bedding, it is sufficient to use a dedicated timer with a small unit time interval for operation control of the bedding. Compared to the case where a known futon dryer is used for bedding heating, the operation control time is set. The operation itself becomes easy, and it is possible to prevent the occurrence of overheating and insufficient heating due to variations in the set time length. Accordingly, it is possible to reliably and efficiently ensure a truly comfortable sleeping environment while sufficiently achieving the effects of reducing energy consumption and running cost. Moreover, since it is a heating device dedicated to bedding, it requires less heat energy than a futon dryer, so even if you use a hose that is smaller or flatter than the hose that comes with the futon dryer. Since the specified heating function can be fully exerted, the gap formed at the insertion point of the hose can be made very small, and the heat of the sleeping space is prevented from escaping outside through the gap as much as possible. Thus, there is an effect that the temperature in the sleeping space can be reliably maintained over the length of time necessary for the temperature of the sleeping space to rise to a comfortable temperature due to the body temperature of the sleeping person.

  In the heating device for bedding according to the present invention, as described in claim 4, when the sleeping space or the upper and lower beddings rises to a set temperature, in addition to means for automatically stopping the operation of the hot air generation source, It is preferable to include a means for automatically pulling out at least the other end of the hot air feeding hose inserted between the upper and lower bedding from between the upper and lower bedding.

  In this case, when the sleeping space or the upper and lower bedding rises to the set temperature and the operation of the hot air generating source is stopped, at least the other end of the hose inserted between the upper and lower bedding is pulled out, thereby By eliminating the gaps formed on both sides of the insertion point, the escape of heat in the sleeping space to the outside can be reduced, the temperature holding time in the sleeping space can be further increased, and foreign matter ( There is no hose end), and the comfort of the sleeping environment can be further enhanced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an external perspective view showing a first embodiment of a bedding heating apparatus according to the present invention, FIG. 2 is an external front view, and FIG. 3 is a schematic front view showing a use mode thereof. The sirocco type has a built-in hot air generating source 12 and a manual hose winding mechanism 13 which are constituted by a blower fan 10 and an electric heater 11 disposed at the blower opening portion, and a gusset on the front and side surfaces. Floor-type box-type case-like device body 2 in which air intake ports 14 (preferably these air intake ports 14 are provided with dust removing filters) are formed, and one end portion 3A is connected to the hose winding. The mechanism 13 is connected to the hot air outlet 12a of the hot air generating source 12 through the hollow rotary shaft 16 of the hose winding rotary reel 15, and the other end 3B has an upper bedding 4 such as a comforter and a mattress or the like. Mattress etc. Formed by and a hot air feed hose 3 is opened so as to blow the inserted hot air to sleeping space 6 between the upper and lower bedding 4,5 between the lower bedding 5.

  The hose winding mechanism 13 is the same as a well-known winding mechanism for winding a cord or a watering hose in a vacuum cleaner, for example. A substantially U-shaped support support 17 in which a hose winding rotary reel 15 with an auto-stopper that can be pulled out to a length and can be fixedly held is fixed in the apparatus main body 2 via the hollow rotary shaft 16 described above. It is supported in a freely rotatable manner. A winding handle 18 for rotating the rotary reel 15 in the hose winding mechanism 13 in the hose winding direction is provided outside the front surface of the apparatus main body 2. Further, an iron plate weight 19 is fixed to the bottom of the apparatus body 2 so that the heating apparatus 1 is stably installed so that the heating apparatus 1 does not fall down or move unexpectedly when installed on the floor. In the figure, reference numeral 23 is a power connection outlet, and 25 is a handle.

  As the hot air supply hose 3, a small-diameter heat-resistant hose having a diameter d of about 50 to 60 mm is used, and the device main body 2 is wound and laminated on the outer periphery of the rotary reel 15 in the hose winding mechanism 13. The other end portion 3B that is pulled out and inserted between the upper and lower beddings 4 and 5 has a channel cross-sectional area equal to the channel cross-sectional area of the other hose portion, as clearly shown in FIGS. The flat hose other end 3B is configured to be detachable from the hose 3 via a joint 3J. Here, the other end portion 3B of the hose is flattened because when the other end portion 3B of the hose is inserted between the upper and lower beddings 4 and 5, no gap is generated or generated on both sides of the insertion location. Even so, the gap is extremely small.

  As shown in FIG. 4, a temperature sensor 7 is attached to the tip of the outer surface of the flattened hose other end 3B, and this temperature sensor 7 is provided on the apparatus main body 2 side. When a preset temperature is detected by operating the temperature setting dial 8, the detected signal is sent to the control unit 20 of the hot air generation source 12 via the signal line 9 laid along the hose 3. The operation of the hot air generating source 12 is automatically stopped when transmitted. Specifically, the switch SW interposed in the electric power heater 11 and the driving power circuit 21 of the blower fan 10 constituting the hot air generation source 12 is automatically turned off.

  In the heating device 1 for bedding configured as described above, the temperature setting dial 8 is operated so that each sleeping person sets an arbitrary temperature, and only the flat hose other end 3B is placed between the upper and lower beddings 4 and 5. Insert into sleeping space 6. In this state, when the switch SW of the power supply circuit 21 is turned on to start the operation of the blower fan 10 and the electric heater 11 of the hot air generation source 12, the hot air generated by the hot air generation source 12 is supplied from the hot air outlet 12a. The temperature in the sleeping space 6 is gradually increased by being directly blown into the sleeping space 6 from the flat other end 3B through the hollow rotating shaft 16 and the hose 3 of the hose winding rotary reel 15.

  When the temperature in the sleeping space 6 or the temperature of the upper and lower beddings 4 and 5 itself reaches a preset temperature, the temperature sensor 7 performs a detection operation, and the detection signal is transmitted to the control unit 20 via the signal line 9. Then, the switch SW of the power supply circuit 21 is automatically turned off, the generation and supply of warm air are stopped, and the sleeping space 6 is warmed to the temperature set by the sleeping person.

  Since the warm air generated by the warm air generation source 12 is directly blown into the sleeping space 6 through the hose 3, no foreign matter is present in the sleeping space 6, and the original softness and slope of the bedding can be obtained. Keeping the sex as it is and not giving the sleeper any sense of incongruity, but also making the sleeping space 6 rapidly rise to the set temperature by making the best use of the thermal energy of the hot air blown in. Is possible. Moreover, since only the flat hose other end 3B is inserted between the upper and lower beddings 4 and 5, the gaps formed on both sides of the insertion location are very small, so that the warm sleeping space 6 The heat in the sleeping space 6 hardly escapes to the outside, and the temperature in the sleeping space 6 is surely ensured over the length of time necessary for the sleeping space to rise to a comfortable temperature due to the body temperature of the sleeping person. It is possible to hold.

  6 and 7 are a schematic longitudinal sectional front view and a schematic longitudinal sectional side view showing a second embodiment of the heating apparatus for bedding according to the present invention, and the heating apparatus 1 for bedding according to the second embodiment is the first embodiment. As described in the example, when the sleeping space 6 or the upper and lower beddings 4 and 5 themselves rise to a preset temperature, the detection signal of the temperature sensor 7 is transmitted to the control unit 20 and the switch SW of the power supply circuit 21 is automatically set. In addition to being configured to turn off and automatically stop the generation and supply of hot air, the flat other end 3B of the hot air supply hose 3 inserted between the upper and lower beddings 4 and 5 As means for automatically pulling out between the upper and lower beddings 4 and 5, the rotating reel 15 in the hose winding mechanism 13 built in the apparatus main body 2 is automatically driven and rotated in the winding direction of the hose 3 via the motor 22. It is configured.

  In other words, the hollow rotary shaft 16 of the rotary reel 15 in the hose winding mechanism 13 is linked to the motor 22 fixedly supported in the apparatus main body 2 via the timing belt 24, and the operation of the motor 22 is controlled by the switch SW. The power supply circuit 21 is provided with a motor switch that is turned on for a certain period of time in synchronization with the off operation. Since other configurations are the same as those of the first embodiment, the same members are denoted by the same reference numerals, and the description thereof is omitted.

  In the bedding heating apparatus 1 of the second embodiment, when the temperature in the sleeping space 6 or the upper and lower beddings 4 and 5 reaches a preset temperature, the power supply circuit 21 receives a detection signal from the temperature sensor 7. The switch SW is automatically turned off, and the generation and supply of hot air is stopped. At the same time, the motor switch is automatically turned on, and the rotary reel 15 of the hose winding mechanism 13 is driven through the motor 22 for a certain period of time. As a result, the other flat end 3B of the hot air feeding hose 3 is automatically pulled out between the upper and lower beddings 4 and 5. Therefore, the very small gaps formed on both sides of the hose insertion point are completely eliminated, the heat in the sleeping space 6 is less dissipated to the outside, and the temperature holding time in the sleeping space 6 is further increased. In addition, it is possible to eliminate the uncomfortable feeling caused by the presence of the other end 3B of the hose 3 in the sleeping space 6 and to further improve the comfort of the sleeping environment.

  In the second embodiment, the rotary reel 15 is driven and rotated so that only the flat other end 3B inserted between the upper and lower beddings 4 and 5 is pulled out from between the upper and lower beddings 4 and 5. As described above, of course, the entire hot air supply hose 3 including the flat other end 3B may be configured to be automatically wound on the rotary reel 15 of the winding mechanism 13, Since the other end portion 3B of the hot air supply hose 3 is pulled out, the other end portion 3B of the hot air supply hose 3 inserted between the upper and lower beddings 4 and 5 is not necessarily flattened. Good.

  In each of the above embodiments, the temperature sensor 7 detects that the sleeping space 6 or the upper and lower beddings 4 and 5 have reached the set temperature, and the operation of the hot air generation source 12 is automatically stopped. Although a temperature control method using a sensor is adopted, instead of this, the sleeping space 6 or the upper and lower bedding 4 is based on the theoretical warm air supply amount (heat amount) when the hot air generating source 12 is rated. , 5 is attached with a timer capable of setting the rated operating time length necessary for the temperature to rise to the set temperature, and the operation of the hot air generating source 12 is automatically stopped in response to the timing operation end signal of this timer. A so-called temperature control method using a timer (which is well known and its details are omitted) may be employed.

  Further, the hose winding mechanism 13 shown in each of the above embodiments may be omitted, and the hot air supply hose 3 is branched into a plurality of octopus legs to generate a single hot air source 12. The warm air that has been generated can be supplied to a plurality of sleeping spaces at the same time, or the other end 3B of the hose can be inserted into a plurality of locations in the sleeping space 6 so that it can be heated to a comfortable temperature in a shorter time.

  Furthermore, in each of the above embodiments, an electric heater is used as the heat source of the hot air generation source 12, but a small capacity gas heater may be used.
