Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat transfer floor installed in the center of the floor and a warm air blowing floor provided in contact with substantially the entire circumference of the heat transfer floor. The present invention relates to a heating device including a surface and a control device for controlling the surface.

Conventional configurations and their problems In general, floor heating is radiant heating, so it is said to be one of the ideal heating methods that does not require extremely high room temperature and does not cause much variation in temperature distribution. However, the actual situation is that the heating capacity is insufficient and the temperature rises very slowly.

In order to eliminate the above-mentioned disadvantages of floor heating, convection heating and floor heating have been used together. However, when a normal convection type heater is used together with floor heating, Temperature differences and draft effects caused by hot air from convection heaters create discomfort, which negates the benefits of underfloor heating.

FIG. 1 shows the indoor vertical temperature distribution according to each heating method: floor heating A, convection heating B, and combination heating C. In the case of floor heating A, the temperature distribution is almost uniform except near the floor and ceiling surfaces, but when the floor temperature is set to 30°C in consideration of human contact, the rise in room temperature is small. In the case of convection heating B, the area near the floor is cold and the area near the ceiling is very warm, resulting in a large temperature difference between the top and bottom. In the case of heating C, which combines floor heating and convection heating, there is no temperature drop near the floor surface as seen in B, but the temperature near the ceiling similarly becomes considerably high. In this case, in order to make the temperature distribution uniform, it is possible to increase the hot air blowing speed of the convection heater, but this increases the draft area within the heated area, which may result in increased discomfort. I was getting used to it.

Purpose of the Invention In view of the above-mentioned conventional circumstances, the present invention aims to solve the insufficiency of the floor heating system and to provide a comfortable heated space with uniform room temperature distribution and no draft. .

Structure of the Invention In order to achieve the above object, the present invention includes a heat transfer floor surface installed at the center of the floor surface in a heated area, and a hot air blower provided in contact with substantially the entire circumference of the heat transfer floor surface. a control device that detects temperatures at two points, the heat transfer floor surface and the room temperature, and controls power supplied to the heat transfer floor surface and the hot air blowout floor; Air outlet ports are provided around the entire circumference of the heat transfer bed surface.

With the above configuration, it is possible to solve the insufficiency of the floor heating system, and also to obtain a comfortable heated space with uniform room temperature distribution and no draft.

Reference numeral 6 denotes a control device that controls the power supplied to the electric carpet 1 and the hot air fan 3, respectively, based on the floor temperature and room temperature detected by the floor temperature detector 4 and the room temperature detector 5, respectively.

Reference numeral 7 denotes a hot air conduit, and 8 denotes an outlet provided on the heated area side of the hot air conduit 7.

Fig. 4 shows a control block diagram of the heating device in the above embodiment, and Fig. 2, Fig. 3a,
Items with the same number as b indicate the same item,
Therefore, the explanation thereof will be omitted. In FIG. 4, reference numeral 9 denotes a room temperature setting device that adjusts the room temperature set value according to the floor temperature detected by the floor temperature detector 4;
10 is a voltage comparator that compares the signal from the room temperature setting device 9 and the signal from the room temperature detector 5; 11 is a hot air machine supply power that adjusts the power supplied to the hot air fan 3 based on the signal from the voltage comparator 10; It is a regulator. Further, 12 is a floor temperature setting device that adjusts the floor temperature set value according to the room temperature detected by the room temperature detector 5, and 13 is a signal from the floor temperature setting device 12 and a sensor for adjusting the floor temperature setting value according to the room temperature detected by the room temperature detector 5. This is a voltage comparator that compares the signals from 4. Reference numeral 14 denotes an electric carpet supply power regulator that adjusts the electric power supplied to the electric carpet 1 based on the signal from the voltage comparator 13.

In the above configuration, since the warm air blowing floor surface 2 is arranged around the electric carpet 1,
In the living area on the electric carpet 1, the start-up of the floor heating is accelerated without creating a draft due to warm air, and the lack of capacity is resolved. Moreover, the effect of energy saving is also produced due to the action of the air curtain created by the warm air blown from the hot air blowing floor surface 2.

Furthermore, when the control device 6 is used, the power supplied to the electric carpet 1 is adjusted according to the room temperature, and the power supplied to the hot air fan 3 is adjusted according to the floor temperature. Comfortable control can be performed.

That is, as shown in FIG. 5, the control characteristic is that when the room temperature is high, the floor surface temperature is low, and when the floor surface temperature is high, the room temperature is low. Furthermore, this control method can prevent excessive input of heat into the heated area, thereby making it possible to make the vertical room temperature distribution on the electric carpet uniform.

In the above-described embodiment, the hot air blowing mechanism includes a hot air fan 3, a hot air pipe 7 directly connected to the hot air fan 3, and a blower provided on the heated area side of the hot air pipe 7. Although the explanation has been made with a configuration consisting of the opening 8, a configuration in which the warm air conduit pipe 7 is not provided, the inside of the hot air blowing floor surface 2 is a space, and the blowing outlet 8 is opened on the top surface can also be used in the same manner as in the above embodiment. The following effects can be obtained.

Further, even if a high temperature heater is installed in the warm air blowing floor surface 2 to generate natural convection, the same effect as in the above embodiment can be obtained.

This makes it possible to obtain a comfortable heated space without drafts.
