Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating tatami, which has a heat storage type heating element built into a tatami mat to comfortably warm a human body and bedding from below.

[0002]

[Prior art]

 In conventional floor heating systems, an electric heater, warm air, and hot water are passed under the floor between the boards to directly heat the floor boards, such as those with floor heating equipment and electric carpets with surface heating elements. Some people use a contact-type heating system that touches the human body and lays it on the floor.

[0003]

[Problems to be solved by the device]

 However, in order to heat a Japanese-style room underfloor, since the room itself has high air permeability, floor heating that heats the underfloor is inefficient, and especially in a Japanese-style room, tatami mats with poor thermal conductivity are spread over the floor. The heat for heating the underfloor is difficult to transfer to the person sitting in the room by direct heat transfer. Western-style electric carpets are provided as contact-type floor heating, but they do not fit in a Japanese-style room and may interfere when not in use.

The present invention provides a heating tatami mat that directly heats a person living in a room without damaging the landscape of the room in a Japanese style and reduces heat dissipation when no person is present. And is intended.

[0005]

[Means for Solving the Problems]

 The present invention encloses a latent heat storage material in a flat bag, and a heating element formed by superimposing an electric heater unit on the lower surface of the bag, and a heating element provided above the heating element, which is relatively thin and flexible. A first heat insulating plate, a second heat insulating plate provided below the heat generating element and having a thickness thicker than that of the first heat insulating plate and having a high bending strength, and a second heat insulating plate provided around the heat generating element and having substantially the same thickness as the heat generating element. By providing a spacer having the same heat insulating property and hardness as the second heat insulating plate and the tatami mat stretched on the upper surface of the first heat insulating plate, the above-mentioned problems can be solved.

[0006]

[Action]

 The tatami of the present invention automatically heats the latent heat storage material from below to an appropriate temperature by an electric heater unit to store heat, and when a person sits on the tatami, the upper insulation material is compressed to improve heat dissipation. Then, the heat stored in the heat storage material is radiated toward the human body.

【Example】

 The drawings show an embodiment of the present invention. The heating tatami mat (A) has the standard size of a tatami mat, (1) is a tatami mat, and (2) is a helicopter. The material of the first heat insulating plate (3), which is covered with the tatami mat (1) and has a small thickness (8 mm), is highly elastic and flexible, and has a high heat retaining property in a non-compressed state, such as porous material. It is a flexible polyurethane foam.

The lowermost layer of the heating tatami mat (A) is provided with a substrate (4) made of a material such as a particle board, a pan or a board, which is relatively lightweight and has a high degree of heat insulation and bending rigidity, and the upper surface thereof. A second heat insulating plate (5) having a bending strength higher than that of the first heat insulating plate (3) and a hardness higher than that of the first heat insulating plate (3) and having a large thickness (20 mm) is provided.

The second heat insulating plate (5) may be made of the same material as the first heat insulating plate (1), but the hardness of the second heat insulating plate (5) is made harder so that it can be easily pressed by a finger. Hard enough not to dent. A spacer (6) made of the same material as the second heat insulating plate (5) but slightly thicker (22 mm) than the second heat insulating plate (5) is narrowed between the first heat insulating plate (1) and the second heat insulating plate (5). It is set up. The second heat insulating plate (5) and the spacer (6) may be made of rigid polyurethane foam and integrally molded.

A plurality of heating elements (3 in the embodiment) surrounded by the first and second heat insulating plates (3) and (5) and the spacer (6) contain the following heating elements (7). Has been done.

The heating element (7) is a sodium acetate-based latent heat storage agent having a large latent heat of dissolution and a transformation temperature of about 50 ° C. in a strong and flat bag (8) made of a synthetic resin film having high heat resistance. (9) and an impregnated base material (10) such as polyester felt, and the lower surface is covered with a heat-resistant insulating material such as silicon rubber, and the heating wire is bent in a meandering shape (11) When the aluminum foil (12) is attached to the upper and lower outer surfaces of the bag (8) with an adhesive, it is sealed between the bag and the bag (8).

The cord heater (11) of each heating element (7) is provided with a temperature switch (13) that opens at about 60 ° C. and closes at about 40 ° C. at the key points, and the cord heaters (11) are connected in parallel. The connector (14), the cord (15) and the plug (16) can be connected to the power source.The cord heater (11), temperature switch (13), cord (15), plug (16) ), Etc. form the heater unit.

In the above-mentioned heating tatami of the present invention, when each cord heater (11) is energized, the generated heat is stored as latent heat while each latent heat storage agent (9) is heated and liquefied to store each latent heat storage. When the agent (9) liquefies and ends heat storage, the temperature rises rapidly and each temperature switch (13) automatically opens to stop energization.

After the latent heat storage material (9) has stored heat, the energization is stopped by a required switch, or even if the plug (16) is pulled out from the power source, the latent heat is released according to the ambient temperature. The latent heat is continuously released until each latent heat storage agent (9) solidifies. Normally, it is controlled by the temperature switch (13), so when the latent heat is completely discharged, the temperature of the latent heat storage agent (9) drops rapidly, and the temperature switch (13) automatically closes and is energized. The heat of (9) is stored again.

The first heat insulating plate (3) in the upper part of the heating tatami mat (A) has a relatively high heat retention property in the normal non-compressed state, and the upper heat insulating plate (3) from the heating element (7) to the tatami mat (1). The amount of heat released is kept small to accelerate the heating of the latent heat storage material (9), and after the end of the heat storage of the latent heat storage material (9), the heat dissipation is kept relatively low.

When a person resides in the room, the first heat insulating material (3) on which the person is placed and pressed increases the heat dissipation due to the compression, and the heat is transferred to the pressed portion. A person usually sits on this pressing portion or sleeps with a bunten, so the heat of the latent heat storage material (9) is transferred to the person who lives in the room, and the efficiency is improved. High heating can be performed.

The second heat insulating plate (5) prevents the stored heat from leaking unnecessarily toward the floor, and the substrate (4) made of particle board imparts rigidity to the heating tatami (A) and heat The aluminum foil (12) keeps the temperature of each part of the latent heat storage agent (9) in each heat-generating body (7) uniform due to its high thermal conductivity to prevent heat generation. Move the body (7) efficiently.

As the heat storage agent (9), polyethylene glycol or the like can be effectively used instead of the sodium acetate type.

[0019]

[Effect of device]

 The present invention has the following effects. (a) When a person lives in the room, heat is transmitted to the person, so efficient heating can be performed. (b) The appearance of the heating tatami mat of the present invention is exactly the same as that of the conventional tatami mat, so it does not spoil the view of the Japanese-style room. (c) Since it does not heat the air in a Japanese room with high ventilation, it does not consume unnecessary power and has high heating efficiency.
