Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating bed having a function of heating a sleeping person on a bed together with bedding.

[0002]

2. Description of the Related Art As a means for warming a person sleeping in a bed, an electric blanket used in combination with a bedding such as a futon has been conventionally used. In addition, a water bed having a function of warming a sleeping person on the bed by heating the bed with warm water has been developed.

[0003] By using such a heating means, it becomes possible to sleep in a warm and comfortable state even in the winter season when the indoor temperature decreases, so that the elderly or sick persons who are not good at the cold in winter or It is effective in ensuring a good night's sleep for people with coldness.

[0004]

In the case of an electric blanket, since a sleeping person is warmed by laying it on a mattress, there is a possibility that a sufficient heating effect cannot be obtained due to a shift during sleeping. Since the protective layer of the heater, which is a heat source, is thin in structure, the heater may be broken by an external impact and may be damaged. Furthermore, in the case of the conventional electric blanket, it is not possible to sufficiently warm a bed under the electric blanket, and thus it is not possible to prevent the occurrence of ticks or the like.

On the other hand, in the case of a water bed in which a bed can be heated with warm water, the effect of heating a sleeping person is sufficient, but the equipment is large and cannot be easily adopted.

In order to solve such a problem, it has been developed as a component for floor heating equipment and the like.

Japanese Utility Model Application Laid-Open No. 61-93709 and Japanese Utility Model Application Laid-Open No. 62-1315.
No. 34, Japanese Unexamined Utility Model Publication No. 63-52287, etc., using a sheet heating element or a plate heating element,
It is conceivable to form a heated bed.

However, in the case of these planar heating elements or plate-shaped heating elements, a reinforcing material or the like is provided to prevent the heating elements from being damaged by an external impact or the like. Since the distance to the heat generating surface is often large, the heating efficiency is low, and a uniform and sufficient heating effect may not be obtained.

Accordingly, an object of the present invention is to provide a heating bed which has high heating efficiency, can obtain a uniform heating effect, and has excellent impact resistance.

[0009]

In order to solve the above-mentioned problems, a heating bed according to the present invention comprises a bed support on which a lower cushioning material, a heat insulating material, a sheet heating element, an upper cushioning material and a heat transfer member are placed. , The sheet heating element and the heat transfer member are connected by a heat conductive material, and a cotton-like body is placed on the upper surface of the heat transfer member.

[0010] With this configuration, the sheet heating element is sandwiched between the lower cushioning material and the heat insulating material and the upper cushioning material. Is less likely to be damaged, and the impact resistance is improved. In addition, since the heat of the sheet heating element is efficiently transmitted to the heat transfer member by the heat conductive material, the heating efficiency is increased, and the cotton-like body on the upper surface of the heat transfer member can be uniformly heated, and the uniformity can be obtained. A heating effect can be obtained.

In this case, it is possible to use a sheet heating element which generates heat when energized, but a sheet heating element having a property of increasing electric resistance as the temperature rises, that is, having a so-called self-temperature control function. In this case, the heat generation temperature can be maintained substantially constant without providing a temperature control circuit or the like. Further, if a planar heating element having a self-temperature control function and a temperature controller are used in combination, it is possible to perform more accurate and stable temperature control. If the maximum heating temperature of the sheet heating element is set at about 50 ° C.,
The occurrence of pests such as mites can be prevented.

Here, a slit is formed in the upper cushioning material,
A structure in which a heat conductive material is arranged through the slit can be adopted. With such a structure, the heat of the planar heating element can be efficiently transmitted to the heat transfer member located above the heat generating member via the heat conductive material without impairing the strength and function as the cushioning material. As a result, the heating efficiency is increased, and a uniform heating effect can be obtained.

In this case, since the heat transfer member and the heat conductive material are formed of an aluminum sheet material, the heat transfer member and the heat conductive material are relatively lightweight, have high heat conductivity, and are excellent in corrosion resistance. The heating efficiency is increased, the durability is improved, and the bed can be reduced in weight.

Further, the flocculent fiber may be coated or impregnated with a powder of an object generating negative ions and far infrared rays. The fluffy body is coated or impregnated with powders of natural minerals such as tourmaline, ceramics, bamboo charcoal, and other objects that generate one or both of negative ions and far-infrared rays. Removal of accumulated cations, heat retention effect, cell activation effect, etc. can be obtained.
