Abstract

PURPOSE:To produce a cooling effect when a surface temperature goes too high and to promote convection heat transfer, by a method wherein, in response to signals from a position detecting sensor and a surface temperature sensor mounted on the surface of a floor heating panel, a blower and a discharge direction of the air through a supply opening are controlled. CONSTITUTION:When the surface temperature of a floor heating panel 1 is high, a thermistor 11 detects a surface temperature, and the position of a user on the floor heating panel 1. Signals from the sensors causes driving of a step motor 7 and a blower 5 through the working of an amplifying circuit 13, a relay 14, etc. The forward and the reverse running position of the step motor 7 are determined by the actuation of specific elements out of a number of piezo-electric elements 12 on the floor heating panel 1, and thus, a vane 10 of a supply opening 6 changes its angle properly, and the air is discharged in the direction of a user's position. This increased an airflow around the user to produce a cooling effect, to immediately relieve the user of heat. The air discharged at this time causes promotion of convention heat transfer on the surface of the floor heating panel to increase a room temperature also.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a control device for floor heating.

BACKGROUND OF THE INVENTION Conventionally, this type of technology has often been constructed with a flat plate 15 having a heating element 16 inside, as shown in FIG.

Problems to be Solved by the Invention However, with the above configuration, even if the heating element is controlled, the user is not fully satisfied. That is, what is commonly experienced while using a conventional floor heating system is that the surface humidity of the floor heating system becomes too high, causing discomfort. In this case, even if the user were to adjust the temperature of the heating element, the adjustment itself is complicated and the response speed is slow. Additionally, when the above adjustments were made, when the room temperature dropped, the radiation effect from the surface of the floor heating system to the human body also decreased, causing the body as a whole to feel colder. .

Means for Solving the Problems In order to solve the above problems, the floor heating system of the present invention includes a blower at one end of the floor heating panel that has a heating element inside.
A box body having an air outlet provided with a means for changing the air blowing direction is installed, and in response to signals from a position detection sensor and a surface temperature sensor provided on the surface of the floor heating panel,
The air blower is configured to include a control circuit that controls the air blower and the blowing direction of the air outlet.

Function: With the above-described configuration, the present invention detects the position of the user when using the floor heating panel with a position detection sensor, detects the surface temperature of the floor heating panel with the surface temperature sensor, and sends the signal to the air outlet. This information is transmitted to the control circuit that controls the blower and blow direction. If the surface temperature is higher than the set value, the blower is activated and the blowing direction of the blower outlet is set toward the user. This increases the wind speed around the user, creating a cooling effect that immediately relieves the heat. In addition, the air blown out at this time promotes convective heat transfer on the surface of the floor heating panel, raising the room temperature.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings. In Figures 1 and 2, 1 is the floor heating panel body;
It has a heating element 2 inside, a large number of piezoelectric elements 12 on the floor heating panel 1 as a position detection sensor, and a thermistor 11 as a surface temperature sensor. 3 is a box installed at one end of the floor heating panel 1, and has a blower 4, an inlet 5, and an outlet 6. The blower outlet 6 moves the support rod 9 up and down via its shaft 8 by normal rotation and reverse rotation of the step motor 7, and as a result, the blades 10 are rotated.

In FIG. 3, when the surface temperature of the floor heating panel 1 is high, the thermistor 11 detects the surface temperature and also detects the position of the user on the floor heating panel 1. Signals from these sensors drive the blower 5 and step motor 7 via the amplifier circuit 13, relay 14, etc. It is assumed that the normal rotation and reverse rotation positions of the step motor 7 are determined in advance depending on which position of the many piezoelectric elements 12 on the floor heating panel 1 is activated. Therefore, the blades 10 of the air outlet 6 change their angle appropriately and blow out the air in the direction of the user's position as shown in (a), (o), or (c) in FIG.

Effects of the Invention As described above, the floor heating apparatus of the present invention provides the following effects.

(1) The air blower inside the box pair and the blowing direction are controlled according to the signals from the user's position detection sensor and the surface temperature sensor installed on the surface of the floor heating panel, so the temperature on the surface of the floor heating panel is controlled. If the temperature gets too high, a cooling effect can be obtained immediately.

(2) Since the air blown out from the air outlet promotes convective heat transfer on the surface of the floor heating panel, the room temperature does not rise and the user does not feel cold.
