Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bed equipped with a heating device that uses warm air to achieve an efficient and healthy heating effect.

[Prior Art] Conventionally, heating means for heating bedding such as futons include, for example, hot water bottles, electric hot water baths, or blankets and bed sheets incorporating heat transfer heaters. However, since the heating effect of hot water bottles and electric foot warmers is localized, it is difficult to obtain comfortable warmth. Furthermore, safety is also an issue because there is a risk of burns from hot water bottles leaking, and low-temperature burns from electric hot water bottles. On the other hand, although blankets and sheets that incorporate heat transfer heaters can provide an overall heating effect, it is difficult to achieve temperature distribution such as cold head and warm feet.
There are problems such as discomfort due to the weight and shape of the heat transfer wire, and bad odors caused by sweat and other substances caused by long-term use, and considering the need to wash the fabric, it is difficult to easily obtain a comfortable heating effect. Another big problem is that it is difficult to ensure safety, as there are concerns about electric shock and other problems.

[Object of the Invention] An object of the present invention is to provide a bed equipped with a heating device that has a simple configuration and provides a healthy and comfortable heating effect.

[Summary of the Invention] The gist of the present invention to achieve the above-mentioned object is to lay a plurality of ventilation panels on a substrate, and stack heat transfer plates with good thermal conductivity on these ventilation panels to create a closed space. A bed equipped with a heating device, comprising a hollow bed base having a heating device, heating means for heating air in the closed space, and means for circulating the heated air in the closed space. be.

[Embodiments of the invention] The present invention will be explained in detail based on illustrated embodiments.

FIG. 1 shows an embodiment of a bed equipped with a heating device according to the present invention, FIG. 1 is a plan view, FIG. 2 is a front view, FIG. 3 is a side view, and FIG. For example, a plurality of ventilation panels are placed on a heat-insulating substrate 2 supported by a bed support 1. 3 are closely juxtaposed as shown in FIG. 5 except for the vicinity of the head. The ventilation panels 3 are molded from a synthetic resin material such as polypropylene, and as illustrated in FIGS. 6 to 9. A large number of through holes 3b are formed in the upper wall portion 3a, and the space below the earthen wall portion 3a is held by a support body 3C consisting of an appropriate number of columnar bodies or wall-like bodies.

Further, in order to promote air flow, it is advantageous to provide a groove 3d in the upper surface of the earthen wall portion 3a that communicates with the through hole 3b.

On the upper side of the ventilation panel 3, a heat transfer plate 4 made of a material with good thermal conductivity, such as an aluminum plate, is stacked to form a hollow bed base 5 having a closed space. Heating and blowing means 6 consisting of a fan are provided. This heating and air blowing means 6 is installed in a closed space, and it is preferable to install it at a location corresponding to the toes as shown in FIGS. 1, 2, and 5. , the first
As shown in the figure, by providing a guide wall 7 to guide the flow of heated air, heating air flows from the feet to the head as shown by the arrow, deflects to both sides from near the shoulders, and returns to the feet. It is possible to create air flow. The guide wall 7 may be formed integrally with the ventilation panel 3, or may be constructed by pasting tape or the like on the side surface of the ventilation panel 3, or by sandwiching a suitable plate material between the ventilation panels 3. It can also be formed. In addition, near the head, there is a board with approximately the same thickness as ventilation panel 3.

Note that it is necessary to close the side surfaces of the outer periphery of the hollow bed base 5 by some means, but this can be done by forming side walls in advance on the ventilation panel 3 located on the outer periphery, or by applying tape or the like to the sides. This can be solved by pasting it. As the heating means installed inside the hollow bed base 5, a highly safe semiconductor heater such as the ceramic 2 heater mentioned above is most suitable, and the blower fan can be extremely small. Timely activated by temperature control operation.

In fact, in order to obtain a healthy and comfortable heating effect, it is sufficient to stack a mattress 9 etc. on the heat transfer plate 4. Air circulates in the internal space of the hollow bed base 5, and the heat is transmitted to the heat transfer plate 4 having high thermal conductivity through the through holes 3b, so that bedding such as the mattress 9 can be efficiently heated from the bottom surface.

Note that the heat transfer plate 4 does not necessarily have to be a metal plate, and even a plywood plate or the like can be used as long as the thickness is appropriately selected. Further, it is also suitable to spread a carpet or a tatami mat over the heat exchanger plate 4.

The hollow bed base 5 constructed in this manner is as follows.

The guide wall 7 creates a temperature gradient that is warm at the feet and low at the head side along the airflow as shown by the arrow in FIG. 4, thereby realizing an ideal cold head and warm foot condition, which can withstand long-term use. Note that the board 2 not only has a heat insulation effect, but also has a ventilation panel 3.
It has the effect of distributing the load applied to the support body 3C.

Regarding the number and size of the through holes 3b provided on the upper surface of the ventilation panel 3, in order to increase the contact area between the heated air inside the hollow bed base 5 and the heat transfer plate 4, the mechanical strength of the ventilation panel 3 is determined. It is advantageous to make the pore area as large as permissible. In addition, the ventilation panel 3 located at the corner of the bed has a curved guide portion 3e as shown in FIG.
However, it is necessary to change the direction of air in the ventilation panel 3 provided at this corner, so as shown in FIG. It is possible to change direction with less air resistance.

Furthermore, a space communicating with the closed space of the hollow bed stand 6 is further provided at the lower part of the hollow bed stand 6, and a heating means is arranged in this space to increase the heat capacity, thereby reducing temperature changes imparted to the load. be able to.

[Effects of the Invention] As explained above, a bed equipped with a heating device according to the present invention has a hollow bed base formed by stacking a heat transfer plate on a ventilation panel with a large number of holes in the upper surface, and Since heated air is circulated within the closed space, the temperature inside the closed space can be raised with a small amount of energy, and the heat efficiently warms the bedding through a heat transfer plate with good thermal conductivity. There is no need to worry about localized heat generation, electric shock, or fire.Also, since it uses an indirect heating method of heating with warm air through a heat transfer plate, it provides a comfortable warmth and prevents burns and low temperatures. It does not cause burns to sleeping people.
