Description

[Detailed description of the invention] (Technical field) The present invention relates to electric carpets.

(Background Art) Two types of conventional electric carpets have been proposed: a type in which the temperature controller section (operation section) is separated from the electric carpet body, and a so-called direct-mount type in which the temperature controller section is adjacent to the electric carpet body. .

By the way, conventional temperature controllers have functions related to heating, such as a temperature control function and a timer function, but do not take into account drying of the air that accompanies heating.

That is, an electric carpet with a humidifying function has not yet been proposed.

(Objective of the Invention) The present invention was proposed in view of the above points, and it is possible to provide an electric carpet with a humidifying function section, and to not only perform heating, which is the purpose of the electric carpet itself, but also to reduce the dryness of the air caused by heating. The aim is to provide a controllable electric carpet.

(Disclosure of the Invention) The present invention will be described in detail below with reference to the drawings showing embodiments.

FIG. 1 is a perspective view showing the main parts of an electric carpet according to an embodiment of the present invention. This is a humidifying function section. The humidifying function section 3 is formed at a position where it does not have any influence on the heater section of the electric carpet main body 1, that is, where it does not get in the way. That is, the mounting position of the humidifying function section 3 is set so that it can operate even when a carpet cover is used or when an electric gotatsu is used together.
It is provided in the end line direction (edge) of the electric carpet main body 1.

In addition, although the figure shows a case where the temperature controller section 2 is provided with the humidification function section 3, a type in which the temperature controller section 2 is separated,
Alternatively, even if the temperature controller section 2 is directly attached, the humidifying function section 3 may be provided on the electric carpet main body 1 separately from the temperature controller section 2. The humidifying function section 3 is formed to be detachable from the temperature controller section 2 or the electric carpet main body 1.

FIGS. 2A to 2C show an example of setting the positions of the temperature controller and the humidifying function section in the electric carpet main body, and the same reference numerals indicate the same parts as in FIG. 1. That is, 1 is the electric carpet main body, 2 is a temperature controller section, and 3 is a humidifying function section.

Therefore, in all of the usage forms shown in FIG. ).

Next, the temperature controller section 2 and the humidification function section 3
The internal configuration of is explained below.

FIG. 3 is a block diagram showing the electrical configuration of the entire electric carpet. In the figure, 4
is a carpet heater, and both ends are connected to AC power supply via relay contact 7 and power switch PSW.
Temperature control is performed by appropriately turning on and off the relay contact 7. Further, 6 is a heat-sensitive electrode adjacent to the carpet heater 4 via the nylon thermistor 5, and by applying the oscillation signal (control signal) of the oscillator OS to the heat-sensitive electrode 6, the impedance of the nylon thermistor 5 changes, that is, the temperature changes. A signal corresponding to the
The noise is removed by a filter circuit F, the level is determined by a switching circuit SW, and temperature control is performed by driving a relay.
Note that CV is a power supply circuit for supplying power to the circuit section, and T is a transformer for supplying stepped-down AC voltage to the power supply circuit CV.

On the other hand, 3' is a humidifying function block, which consists of a humidifying circuit H, a transistor Q, a humidifying heater 8, and a humidifying tank 9. By heating the humidifying tank 9 with the humidifying heater 8, the water in the humidifying tank 9 is turned into steam. It is designed to diffuse into the atmosphere above the electric carpet.

Regarding operation, when the user turns on the power switch PSW of temperature controller section 2,
The carpet heater 4 generates heat, the impedance of the nylon thermistor 5 changes, and the signal voltage level of the heat-sensitive electrode 6 gradually changes. This signal is then input to the switching circuit SW and the humidifying circuit H through the filter circuit F for noise removal.

The humidifying circuit H operates when the signal from the filter circuit F exceeds a certain level (for example, the temperature of the electric carpet body 1 exceeds a certain value), causes the humidifying heater 8 to generate heat, and cools the water in the humidifying tank 9. is converted into steam and diffused into the atmosphere. Note that the operation regarding temperature control is as described above.

In this way, when the temperature of the electric carpet rises above a certain level, the humidity in the room decreases, and the air begins to dry, the humidifying operation is performed, keeping the room air-conditioned comfortably. can.

Although the dedicated humidifying heater 8 is used as the heat source for humidification in FIG. 3, the carpet heater 4 may also be used.

(Effects of the Invention) As described above, in the present invention, in an electric carpet equipped with a temperature controller section for controlling temperature, a humidifying function section that operates depending on the temperature is provided at the edge of the electric carpet main body. So,
In addition to the original heating function, humidity can also be controlled by temperature, which has the effect of maintaining good air conditioning in rooms where electric carpets are used.
