Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sheet-shaped warming tool for warming an electric blanket and sleeping.

[0002]

[Prior Art]

 Conventionally, electric bed blankets and electric blankets have been widely used as sheet heating devices such as electric heating appliances for sleeping, but a function as a heating device to warm the body is sufficient to obtain a comfortable sleeping environment. Was insufficient, and what could provide a better environment was desired.

Conventionally, as a measure for improving such an environment, a means for generating sound, music, fragrance, etc. has been placed in a bedroom and used, but it was not satisfactory. (See, for example, Japanese Utility Model Publication No. 63-179868 and Japanese Utility Model Publication No. 63-181360).

[0004]

[Problems to be solved by the device]

 In recent years, there has been a growing interest in obtaining a comfortable sleeping environment, and various engineers have been working on it. Of these, various products have been announced for voice, as they have a great effect on sleep. However, all of them have a volume that is slightly audible to the ears of music recorded on CDs or tapes and environmental sounds. , Listening creates a comfortable sleeping environment. However, if the volume is reduced, the sound quality will deteriorate and it will be difficult to hear, and the sound will spread to the surroundings with commonly used speakers, etc., and it will be annoying to people around who do not need music. At the same time, the speaker itself had to be installed at the bedside, and its use was limited in a small bedroom environment.

[0007] Although it is possible to use a small speaker such as an earphone, it is uncomfortable because it is inserted into the ear canal, and the cord may be an obstacle, which rather hinders sleep.

[0006]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems and to provide a comfortable sleeping environment. A sound generating device in which a vibrating element that generates sound is attached to a vibrating body is used at the time of sleeping. The heater wire is installed so that it is located in the section, and the heater wire for collecting heat is installed in a meandering manner so that it is located from the shoulder to the foot, and is integrally configured.

[0007]

[Action]

 With such a configuration, it is possible to listen to music and environmental sounds from below the head with a volume that is faintly heard while collecting heat.

In addition, since the voice generator is installed under the head of the sheet-shaped warming tool, the voice is strongly transmitted in the upward direction and is difficult to be transmitted in the lateral direction. It is possible to prevent annoyance to other people and to obtain a comfortable sleeping environment.

【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a simplified structural view of an embodiment of the present invention, and FIG. 2 is a sectional view of part A thereof.

The structure of the present invention is basically a planar heating tool main body including a heat generating portion 1, a sound generating device 3 built in the upper end of the heat generating portion 1, and a connecting portion 4 thereof. Make up 5.

The heating portion 1 has a tunnel-shaped connecting portion formed between napped fabrics, and the heater wire 2 is arranged in a meandering shape. The terminal portion of the heater wire 2 is electrically connected to the connection portion 4 as a whole, and is connected to a controller portion having a control circuit for controlling the temperature to receive power.

On the other hand, in the sound generating device 3, one or a plurality of thin plate-shaped vibrating elements 6 having a high mechanical strength using a piezoelectric element or the like are connected to cause vibration to the flexible resonator 7. It is attached and fixed so that it can propagate efficiently. Since the resonator 7 is used by being built in the sheet heating device main body 5 used as bedding, it has sufficient flexibility so that it does not feel uncomfortable even under a pillow or the like when used. At the same time, it is necessary to select a material that can resonate efficiently with the vibration from the vibrator 6 and obtain a large sound pressure. For this material, for example, a synthetic resin foam, a non-woven fabric, a thin plate, or the like can be used to obtain sufficient performance. The sound generating device 3 is arranged so that two pairs of left and right, or one of them is directed upward in the range of the upper end portion d of the planar warming tool main body 5 of about 30 cm. That is, the pillow is placed so that it is located under the pillow and under the head when sleeping. When using right and left sound sources such as a stereo, the left and right resonators 7 are separately arranged in order to separate the vibrations, and the connection cords 8 and the like are used to connect the vibration-resistant materials. The signal to the voice generating device 3 is configured to be received by the plug portion which is integrated with the connection portion 4 or separately provided.

The voice generator 3 is built in the head of the main body 5, but is easily attached and detached when the main body 5 needs to be washed, such as when it becomes dirty, or when it needs to be repaired due to a failure or the like. For this reason, the accommodating portion of the main body 5 is formed in a bag shape, and the sound generating device 3 can be fixed by a fastener and a simple fixing device, which is easy to handle. Next, the operation of this embodiment having the above configuration will be described below.

As shown in FIG. 1, in the sheet heating device having the above-mentioned configuration, when the connecting portion 4 is connected and the power supply is started, the heater wire 2 is energized and heated, and the heat is passed from the shoulder to the foot through the cloth. And the entire body except the head becomes warm, and a comfortable sleeping environment can be obtained as the temperature environment inside the bed.

Further, by inputting a signal of a favorite sound source to the connecting portion 4 of the connection plug of the sound generating device 3, the vibrating element 6 vibrates in accordance with the signal, and further vibrates greatly together with the resonator 7. Make a sound. At this time, since the voice generator 3 is under the head, the voice propagates as a vibration through the pillow to the entire head, and at the same time, the voice is generated very close to both ears. Since the device 3 is arranged, even if the volume of the sound is reduced so that the sound is slightly audible, the sound can be heard clearly due to the synergistic effect. Furthermore, regarding the influence on the surroundings, the sound as vibration is weak in energy, so it is attenuated before being propagated to the surroundings, and the amount of propagation is small. Since sound waves are also arranged in a plane so that the propagation direction is stronger in the upward direction, the transmission of sound waves in the lateral direction is structurally small, and the influence on the surroundings is extremely small.

[0017]

[Effect of the device]

 As described above, according to the present invention, it is normally used as a warming device at bedtime, and has a function of a warming bed which gives a warming effect to the body as a warming tool when the temperature is low. The sound generator incorporated in the device can generate a desired sound to promote sleep and create a comfortable sleeping environment.

Further, since the structure is such that only the voice generating device can be attached and detached, the above-mentioned effect is obtained when the voice is heard without disturbing the surroundings even after bedtime. Can be used as an effective means.
