Abstract

PURPOSE:To permit to use a room heater in an optimum room heating area with an optimum room heating temperature by connecting and switching a heating body such as an electric carpet or the like properly. CONSTITUTION:In case the whole area of a carpet main body is heated with 1/2 of the full output thereof, for example, the switching terminal 6e of a changeover switch 6 is switched and connected to fixed terminals 6a, 6b, 6c, the heating bodies 4, 5 are connected in parallel with respect to an electric source 13 through a diode 14 to conduct them and the room heating is effected by 1/2 of output. When the whole area of the main body 3 is heated, the terminal 6e is switched and connected to the terminal 6b, 6c, 6d to conduct the heating bodies 4, 5 and the room is heated by the full output. In case only the center A of the main body 3 is heated, the terminal 6e is switched and connected to the terminals 6c, 6d to conduct the heating body 4 only and whereby the center A only is heated. In case the room heating is to be stopped, the terminal 6e is switched and connected to the terminal 6d only to stop the conduction of the heating body 5 and stop the room heating.

Description

[Detailed Description of the Invention] Technological Field of KUBURI J> This invention relates to electric heaters for unexploded EIljtrJ, electric carpets, electric blankets, etc., and specifically relates to electric heaters that can be used in the optimum heating condition for I/IC. be.

<Prior art> In conventional electric heaters, such as electric carpets,
A plurality of heating elements are disposed so as to heat different positions on the entire surface of the carpet body, a switch is provided to control energization of each of the plurality of heating elements, and the switch controls energization of each of the plurality of heating elements. The heating area of the carpet body can be switched to heating the entire surface or a predetermined portion as appropriate.

With an electric carpet configured as described above, the heating area of the carpet body can be switched to heating the entire surface or a predetermined part, but it is not possible to switch the heating temperature of the carpet body to a predetermined state. The drawback was that it could only be used at a heating temperature of .

<Object of the invention> The purpose of the misfire 8A is to obtain an electric heater that eliminates the above-mentioned drawbacks.

<Embodiments of the Invention> Hereinafter, a case where an embodiment of the electric heater of the present invention is applied to an electric carpet will be described with reference to the drawings.

The electric carpet of the present invention has a first heating element 4 disposed in both the lower cloth 1 and the upper cloth 2 of the carpet main body 3 so as to be located at the center A of the carpet main body 3 consisting of the lower cloth 1 and the lower cloth 2. Second heating elements 5 are disposed on both sides B of the carpet body 3 and between the lower fabric 1 and the lower fabric 2 of the carpet body 3, so as to be positioned on both sides of the first heating element 4. , a control part case 8 in which a changeover switch 6 for switching the connection state of the first heating element 4 and the second heating element 5 and switching the energization state is provided at a predetermined corner 7 of the carpet body 3;
, and the lino replacement switch 6 of the control unit case 8
The first heating element 4 and the second heating element 5 are connected to predetermined connection terminals of the
Connect the selector switch 6 of the control unit case 8.
The power supply cord 11 has a connection plug 9 at one end that is connected to a predetermined connection terminal as appropriate, and a power supply plug 10 that is connected to a power source at the other end.

The electrical connection of the electric carpet having the above configuration is as shown in FIG. is connected in the 1114 direction, and the fourth fixed terminal 6d of the changeover switch 6 is connected, and one end of the second heating member 5 is connected to the second fixed terminal 6b of the changeover switch 6, and the second heating element 5 is connected to the other end of the power source 13, one end of the first heating element 4 is connected to the third fixed terminal 6c of the changeover switch 6, and the other end of the first heating element 4 is connected to the other end of the power source 13. It is configured by connecting to the other.

In the above configuration, the first fixed terminal 6a, the second fixed terminal 6b1, the third fixed terminal 6c, and the fourth fixed terminal 6d can be appropriately switched and connected to predetermined states by the changeover switch 6t/''i changeover terminal 6e. configuration, and the changeover switch 6
The first heating element 4 and the second heating element 4 are switched by switching the switching terminal 6e.
The state of energization to the heating element 5 is as shown in the operation explanatory diagram of FIG. 3, and in this FIG. 3, the knob position is the position of the knob 6f of the switching terminal 6e of the changeover switch 6 in FIG.
Ru.

Next, the operating state of the electric carpet constructed as described above will be explained.

□First, when heating all the songs on the carpet body 3 at 1/2 of the total output, the switching terminal 6e of the switching switch 6 of the control unit case 8 is connected to the first fixed terminal 6a, the second fixed terminal 6b, and the third fixed terminal. The diode 1 is connected to the terminal 6C, and the first heating element 4 and the second heating element 5 are connected to the power source 13.
The first heating element 4 is connected in parallel via the first heating element 4.
Then, the second heating element 5 is energized, and the entire surface of the carpet body 3 is heated at the full output of 172, as shown at knob position a in FIG.

If you want to heat the entire surface of the carpet body 3 at full power, switch the switch terminal 6e of the switch 6 of the control unit case 8 to the second fixed terminal 6b1, third fixed terminal 6c, and fourth fixed terminal 6d. Then, the first heating element 4 and the second heating element 5 are connected in parallel to the power source, and the first heating element 4 and the second heating element 5 are energized, and the knobs are positioned as shown in FIG. As shown, the entire carpet body 3 is heated at full power.

When only the center A of the carpet body 3 is heated, the switching terminal 6e of the switching switch 6 of the control unit case 8 is switched and connected to the third fixed terminal 6C and the fourth fixed terminal 6d, and only the first heating element 4 is heated. is connected to a power source to energize only the first heating element 4, thereby heating only the center A of the carpet body 3, as shown by knob position C in FIG.

When heating the carpet body 3 is to be stopped (turned off), the switching terminal 6e of the switching switch 6 of the control unit base 8 is switched and connected to only the 4th i'J constant terminal 6d, and the first heating element 4 and the second heating element 5,
Heating of the carpet body 3 is stopped as shown at knob position d in FIG.

In the above case, for example, if the power consumption of the first heating element 4 and the second heating element 5 is 305 W each, the knob 11 in FIG.
The total output of the carpet body 3 shown by a is 1/of the total output.
When heating at output 2, heating is performed at 305W.
In addition, when heating the entire surface of the carpet body 3 at full power as shown by the knob position in FIG.
l1lj to heat only the center A of: heating by 305W.

In the above embodiment, a case has been described in which the heating area of only the entire surface and the center of the carpet body 3 can be switched, and the heating temperature of the entire surface can be switched. By appropriately switching the connections of the plurality of heating elements, the heating area and the heating temperature can be appropriately switched to a desired state. In addition to electric carpets, it can also be applied to floor heating, electric blankets, etc.

<Effects of Start J> Since the electric heater of Mistake J has the above-mentioned configuration, the heating area can be switched to heating the entire surface or a predetermined part as appropriate, and the heating temperature can also be switched to a predetermined state. Therefore, it can be used with the optimal heating area and heating temperature depending on the usage area and the number of users, and it can perform efficient heating. Furthermore, the power consumption of the heating element can be easily and reliably switched to a predetermined state by simply connecting the diode to the heating element as appropriate using a changeover switch.
