Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to floor heaters such as electric carpet floor heaters and electric mantle heaters.

Conventional configuration and its problems When an overcarpet with a relatively short pile length is used, the human body comes close to the heater unit. At this time, the closer you are to the heating part of the heater, the more directly you will be affected by the heat, and there is a risk of burns due to intense lovemaking. Therefore, the user has no choice but to lower the scale of the controller. However, even if the scale is lowered, since the human body is in contact with the heater, the sensation of stimulation from the heater is only slightly weakened. Therefore, if you shorten the length of time the heater is energized, the irritation will be reduced, but the overall amount of heat generated will also decrease, and the heating effect will be insufficient.

In the above case, especially if a Yagura Kotatsu is used at the same time, the heat from the Kotatsu will be directly received by the heater unit surface, so the person's feet will feel warm but their buttocks will feel cold. It turns out. This is because the heat from the kotatsu activates the temperature sensor in the heater unit, which stops the power supply to the heater, so the bottom of the kotatsu receives cold heat from the floor through the heater unit's insulation. Especially if it is installed above the floorboards, it will feel cold because it is susceptible to the cold air under the floor. The folded top has a relatively good insulation effect, so it doesn't get cold. However, if aluminum foil is used to enhance the heat dissipation effect of the heater unit, it will easily absorb body heat and radiate heat to the insulating material, making you feel a strong sense of cold air around your buttocks.

1. Electric carpets are always turned on during the cold winter months, but in early spring or when it is relatively warm, such as when you are hungry, you can use other heat sources (for example, kerosene stoves) as the main heating device in the room. When there is no need to energize the electric carpet, the temperature of the entire floor becomes low, and the wide areas in particular feel cold.

Therefore, in many cases, a heat insulating mat is installed on the underside of the heater unit's insulating material or on the underside of the overcarpet.

In other words, if it is installed under the heater unit, it will only have the same insulation effect as a tatami mat, which is insufficient, and if it is installed under the overcarpet,
Although it is highly effective in insulating heat from the Yagura Kotatsu, it is also highly effective in insulating heat from the heater unit, so it is not ideal.

OBJECTS OF THE INVENTION The present invention solves the above problems and provides comfort.

Structure of the Invention In order to achieve the above object, the present invention provides a heat storage mat between the heater unit and the overcarpenter.

This heat storage mat is constructed by laminating a fibrous layer and a stiff fibrous layer on a metal-containing layer.

DESCRIPTION OF EMBODIMENTS A in FIG. 1 is a heater unit, and B is a heat storage mat. C is an overcarpet.

As shown in Fig. 2, the heater unit A includes a heating heater 1, a temperature sensor 1', a metal foil 3 such as aluminum foil, and a surface cloth 4.
It consists of Each part is joined using hot melt or adhesive.

Heat storage mano L-B is made of metal foils such as aluminum foil and copper foil, metal-containing resins made by mixing aluminum powder and copper powder into acrylic resin, and metal-plated fibers coated with copper. A metal layer 5, a fiber layer 6 in which synthetic fibers such as polyester fibers and natural fibers such as wool are mixed into a felt shape, and low melting fibers such as polyester fibers and polyethylene fibers are mixed depending on the hardness of the surface part. It is composed of a stiff cotton layer 7 with a different ratio. The thickness of each of these 5 to 7 layers is determined by solidifying the molten fibers using a hot press, compressing the entire fiber with heat, and deforming it by heat. Furthermore, the heat conduction performance can be selected by changing the constituent parts of the metal-containing layer 5 depending on the purpose. For example, if heat absorption is to be increased, a metal foil may be used, and if cost or flexibility is required, a metal-containing resin layer may be selected.

Thermal conductivity is determined by the content of metals.

In addition, heat retention and comfort when a person sits on the floor are achieved by making the fiber layer 6 thicker, and by changing the density of the fibers.In particular, for cushioning properties, increasing the denier of the fibers It is effective because it increases the elastic repulsion force.

The overcarpet C is composed of a pile 8, a base fabric 9, and a backing agent 10.

In the above structure, FIG. 3 shows a conventional example without a heat storage mantle 1-B, and in this embodiment as well, the person sits on the overcarpenter 1-c as shown in FIG. Then, the pile 8 falls down and the wide part comes into contact with the base fabric 9. At this time, the temperature of the x section becomes as shown in FIG.

■ indicates the temperature characteristics when using heat storage mano)B,
@ indicates the temperature characteristics when the heat storage mano [・ is not used (state in Figure 3), ○ indicates the temperature characteristics when the Yagura Kotatsu is used together with heat storage mat B, and O indicates the temperature characteristics when the Yagura Kotatsu is used. The table below shows the temperature characteristics when the heat storage mat B is not used and the Hayagura Kotatsu is not used, the heat storage mat B is not used, and the heater unit A is also turned off, and the floor temperature is 10. It shows the temperature characteristics at °C.

Effects of the Invention In the present invention, since the heat storage cloak is installed between the heater unit and the overcarpet, heat is stored in the fiber layer due to the heat receiving effect of the metal-containing layer, which has particularly good thermal conductivity, and the stored warm air is transferred to the stiff layer. has appropriate breathability,
Convection heat is radiated to the overcarpet, providing comfortable heating.

In addition, in the embodiment, the stiff cotton layer 7 is made of a mixture of low-melting type fibers and the fibers are fused and bonded, which increases tear strength and prevents fuzz from occurring on the surface fibers, reducing pilling caused by shifting of the overcarpet C. .

Since the binding force between the fibers is still strong, the uneven surface of the backing agent 10 is caught, thereby increasing the frictional resistance and also having the effect of reducing the displacement of the overcarpet Cj.

Further, by using a thick denier fiber layer 6, the impact resilience can be further increased, and the cushioning properties are also improved.

In particular, the heat from the Yagura Kotatsu passes through the stiff cotton layer 7, but it is not reflected by the metal layer 5, so the heater unit outer fabric 4
The heating element 1 is not thermally affected, and the heating heater 1 is heated by energization.
