Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric floor heating appliance such as an electric carpet.

[0002]

2. Description of the Related Art In recent years, electric carpets have tended to become high-grade and large-sized, and in particular, it is required to quickly warm a portion where a user is sitting without increasing the maximum power consumption.

A conventional electric floor heating apparatus is Japanese Patent Publication No. 60-21.
There is a structure shown in Japanese Patent No. 470. The configuration will be described below with reference to FIGS. 5 and 6. As shown in the figure, the electric floor heating apparatus includes main heating elements 21 and 22,
It is composed of auxiliary heating elements 23 and 24 and an on / off switch 25 of the auxiliary heating elements 23 and 24.

In the above electric floor heating apparatus, the switch 25 is turned on at the initial stage of energization and the main heating elements 21 and 22 and the auxiliary heating elements 23 and 24 are simultaneously energized, so that the user can warm up faster. ing.

[0005]

However, in the above-mentioned conventional configuration, particularly in a large electric floor heating apparatus of 4 tatami mats or more, which consumes a large amount of power, the main heating elements 21 and 22 are provided at the initial stage of energization.
If both the auxiliary heating elements 23 and 24 are energized at the same time, power consumption of 1 kW or more is required, and with a general parallel outlet, the limit is 1.7 kW (the inrush power is 2 kW and the breaker jumps). If you are using other electrical appliances from the, breaker breaks and cannot be used together. In addition, electric floor heaters with a capacity of 6 tatami mats or more have a problem that even if the power consumption is 1.7 kW, it may take a while to warm up at the beginning of energization, depending on the surface material.

On the other hand, looking at electric carpets, which are typical of recent electric floor heating appliances, there is a trend toward higher quality and larger size. For surface materials, electric carpets made of thick Wilton or dango are also on sale, which are very interior-friendly and have a good texture. Since these high-grade surface materials are thick, it is difficult for the heat from the heating element to pass through, and the warming speed is slow. Furthermore, in recent homes, the living space has become wider, and the number of large electric carpets of 4 tatami mats or more has increased accordingly. However, large electric carpets require high power consumption.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to quickly warm the portion where the user is sitting without increasing the power consumption so much.

[0008]

In order to achieve the above object, the present invention provides one or more main heating elements and a unit of the main heating element in a partial area where the main heating element is arranged. An auxiliary heating element having a heating value larger than the heating value per area is provided, and an energization control section for controlling energization of the main heating element and the auxiliary heating element is provided, and the energization control section energizes the auxiliary heating element. The main heating element in the area where the auxiliary heating element is disposed is configured so as not to be energized when it is on.

[0009]

When the auxiliary heating element is energized by the energization control section, the electric floor heating apparatus of the present invention is operated so as not to energize the main heating element in the area where the auxiliary heating element is arranged. The overall power consumption will be kept low.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG.
The description will be made with reference to FIG.

FIG. 1 shows a wiring state of a heating element of an electric floor heating apparatus. As shown in the figure, the electric floor heating apparatus has main heating elements 1 and 2, an auxiliary heating element 3, and an energization control section. 4 and.

FIG. 2 is an electric circuit diagram of the electric floor heating apparatus. The energization control unit 4 connects the heating elements 1, 2,
Control the energization of No. 3. Main heating elements 1 and 2 are 5 each
It has a power consumption of 00W. The auxiliary heating element 3 has a power consumption of 700 W, and the area A in which the auxiliary heating element 3 is contained has a heating value larger than the heating value per unit area of the main heating elements 1 and 2.

In the above structure, the main heating unit 2 and the auxiliary heating unit 3 are energized by the energization control unit 4 at the beginning of use.
The main heating element 1 is not energized. The total power consumption at this time is 1200 W, and the power consumption in the area A in which the auxiliary heating element 3 is contained is 700 W, and the person using the area A can warm up quickly. At this time, if all the heating elements 1, 2 and 3 are energized, the power consumption will be 1700 W, and the breaker will break. When the area A reaches a predetermined warmth, the energization control unit 4 stops energizing the auxiliary heating element 3 and energizes the main heating element 1. The total power consumption at this time is 100
It becomes 0 W, and the entire electric floor heating appliance is heated with the same amount of heat generated per unit area.

As described above, according to the electric floor heating apparatus of the first embodiment of the present invention, the auxiliary heating element 3 is controlled by the energization control section 4.
Since the main heating element 1 in the area A in which the auxiliary heating element 3 is arranged is not energized when the auxiliary heating element 3 is energized, the area A in which the auxiliary heating element 3 is placed can be warmed quickly. In addition, the power consumption of the entire device can be kept low.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Figure 3
Shows the wiring condition of the heating element of the electric floor heating equipment,
As shown in the figure, the main heating element 11, the auxiliary heating element 12, and the energization control unit 13 are included. FIG. 4 is an electric circuit diagram of the electric floor heating appliance. Each heating element 11, 12 has a power consumption of 900 W, and the auxiliary heating element 1
The area B containing 2 has a larger calorific value than the calorific value per unit area of the main heating element 11. At the beginning of use, the energization control unit 13 energizes the auxiliary heating element 12 and does not energize the main heating element 11. At this time, if all heating elements 1
When power is supplied to 1 and 12, the power consumption becomes 1800 W and the breaker flies. When the area B reaches a predetermined warmth, the energization control unit 13 stops energizing the auxiliary heating element 12 and energizes the main heating element 11. The total power consumption at this time is 900 W, and the entire electric floor heating appliance is heated.

As described above, according to the electric floor heating apparatus of the second embodiment of the present invention, the energization control unit 13 controls the auxiliary heating element 1.
When the second heating element is energized, the main heating element 11 is not energized, so that the area B containing the auxiliary heating element 12 can be warmed quickly and the power consumption of the entire apparatus can be reduced. You can hold it down.

[0017]

As is apparent from the above description of the embodiments, the electric floor heating apparatus of the present invention can be warmed immediately by using the area containing the auxiliary heating element when it is desired to warm up quickly on a cold morning. .. In addition, by not energizing the main heating element in the area where the auxiliary heating element is arranged, the power consumption of this electric floor heating appliance can be kept low. It has the effect of being comfortable to use. Especially, the effect is great in the recent large electric heating appliances of 4 tatami mats or more using a thick surface cloth material having an interior property.
