Abstract

PROBLEM TO BE SOLVED: To enable reduction of cost by utilizing off-peak rate power and to enable rearrangement of mats for all or a necessary number of tatamis already provided, by constituting the mat out of upper and lower mat elements and a heating wire interlaid between them and by providing input and output terminals for electric connection to the heating wire on the outer lateral sides of the mat. SOLUTION: A mat A is composed of an upper mat element 1 and a lower mat element 2 prepared by filling liquid 1b and 2b such as water in closed vessel bodies 1a and 2a made of resin. The mat A is formed in dimensions for one tatami and terminals 5 and 6 for connection of a heating wire 3 are provided on the outer lateral sides of the mat. A desired number of mats A are laid on the floor surface and the terminals of the mats A are connected in series. In this case, a temperature control is conducted automatically by a thermostat detecting the temperature of the mat A and by a controller controlling a set temperature. In this way, heat is stored in the mat A by heating the water in the upper and lower mat elements 1 and 2 by utilizing off-peak rate power, and floor heating in the daytime is conducted by utilizing the energy of this stored heat.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat storage mat for laying on a floor of a house, and more particularly to a heat storage mat for floor heating which can be used as a substitute for a tatami mat. It is.

[0002]

2. Description of the Related Art In recent years, due to the tightness of power demand and the difficulty of constructing a new power plant, a power load standardization system for effectively using nighttime power, suppressing the use of daytime power, and conserving energy has been proposed. Technology development is required. As part of this, thermal storage heating systems using nighttime electricity are being used.

[0003]

However, such a heat storage and heating system is composed of a series of various systems such as installation of a heat storage tank, construction of a circulation pipe connected to the heat storage tank, insulation work of the pipe, and a heat radiating device at a required place. This requires not only expensive equipment, but also retrofitting work to existing houses and buildings, in particular, involves complicated work and expensive work and time. It had the following.

The present invention is in line with the social demand for the technical development of the electric power load standardization system, and is simply laid on a floor requiring heating and in an appropriate required area as a substitute for a tatami mat. The main object of the present invention is to provide a low-cost heat storage mat for floor heating that can be used as a heat storage device that can store heat using electric power at night and dissipate this heat during the day to be used as heating heat. It is.

Another important object of the present invention is to eliminate the need for intensive large heat storage tanks and piping work.
Anyone can easily lay it on the floor without special skills, and according to the size of the room or at an appropriate part of the room, all or the desired number of tatami mats already laid It is an object of the present invention to provide a floor heating heat storage mat which can be used in place of the above.

[0006]

To achieve the above object, a floor heating heat storage mat according to the present invention is provided with an upper mat element 1 having a substantially square shape and a liquid inside, and an upper mat element 1 having a substantially rectangular shape. A mat A is constituted by a lower mat element 2 having a substantially quadrangular shape applied to a lower part of the element and a heating wire 3 interposed between the upper part and the lower mat elements 1 and 2. The input and output terminals 5 and 6 for electrical connection to the heating wire 3 are provided.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In implementing a floor heating heat storage mat according to the present invention having such a configuration, the planar size of the mat A is, for example, one tatami mat or a half tatami mat. The size is about one-quarter of the tatami mat area, such as about one-fourth the size of a tatami half-tatami mat, or one sixth, one eighth, one ninth, etc. It is preferable to form the mat so that the area where the mat is laid can be increased or decreased as desired. When the mat is used together with the tatami mat, the thickness of the upper and lower mat elements 1 and 2 or the thickness of the mat A on which the outer covering material 4a or the outer cover 4 is applied is set to a thickness substantially equal to the thickness of the tatami mat. It is preferable to carry out the process so as not to cause a step at the boundary with the tatami mat.

It is preferable that the material constituting the upper mat element 1, the material 4a, and the material constituting the outer cover 4 are designed so as to maintain appropriate hardness and flexibility. Further, the upper mat element 1 can be embodied as provided with a reinforcing rib, a reinforcing material, or a partition wall, if necessary, in order to maintain appropriate strength. In addition, if the upper surface of the upper mat element 1 is formed in a tatami mat shape, a tatami mat is used as the surface covering material 4a, or a material such as a blanket or a carpet material is laminated, a product that does not require an overlay is used. It can be used as it is.

The lower mat element 2, like the upper mat element 1, may be a flat container having a liquid sealed therein, in which case the upper mat element 1 is substantially formed.
The lower mat element 2 may be a container in which a liquid is sealed inside, and the upper and lower containers may have different thicknesses in the vertical direction. However, the present invention is not limited to this. For example, it may be formed of foamed heat insulating material 2A such as urethane foam or styrofoam. In this case, a foamed material of closed cells is preferable to a foamed material of open cells because it has a better heat insulating effect. Further, it may be formed by a single layer such as a rubber sheet material, a nonwoven fabric or a raised fabric, or a laminate of a sheet-like or board-like material made of a synthetic resin or other materials. Or a material and form having an effect of blocking heat radiation to the lower side and the side.
