Abstract

PURPOSE:To obtain quickly rising and comfortably heated space, by combining a floor heating apparatus with a high-temperature radiation heating appliance such as an electric stove, by separately sensing the floor temperature and the room temperature, and by controlling these temperatures, correlating with each other. CONSTITUTION:The floor temperature and the room temperature are respectively sensed by a floor temperature sensor 3 provided to an electric carpet 1 and by a room temperature sensor 4 equipped in the wall of a room. In accordance with the sensed floor temperature and the room temperature, and with a controlling characteritic curve A as shown in a graph, a room temperature setter 6 and a floor temperature setter 9 calculate the room setting temperature and the floor setting temperature, respectively. When heating is started and both the room temperature ta and the floor temperature tf are elevated up to the equal temperature level, OFF control signals are put into an electric stove power source circuit 8 and an electric carpet power source circuit 11 from voltage comparators 7 and 10, respectively. With such an arrangement, lack of capacity in the electric carpet is eliminated without loosing the comfortability of the electric carpet 1.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a heating device that has industrial application. □ Conventional configurations and their problems In general, floor heating is radiant heating, so it is an energy-saving and comfortable heating method that does not require extremely high room temperatures and causes little variation in temperature distribution within the room. Furthermore, it is said to be an ideal heating method because it does not cause discomfort caused by the warm air directly hitting the occupants as is the case with convection heating.

However, the actual situation is that the heating capacity is insufficient, and the temperature rises very slowly in the initial stage of heating, so that it takes a long time to provide a sufficient sense of warmth to the occupants.

Figure 1 shows a comparison of electric stoves, hot air fans, and floor heating devices regarding the sense of warmth experienced by residents in the early stages of heating.
As is clear from FIG. 1, the rise in temperature of the floor heating system is very slow compared to electric stoves that provide high-temperature radiant heating. Furthermore, the response speed of the floor heating system to disturbances during heating, such as a sudden drop in outside temperature or an increase in the amount of ventilation, is extremely slow.

Purpose of the Invention The present invention aims to solve the above-mentioned conventional problems, and to solve the lack of capacity without losing the advantages of floor heating, and to provide a comfortable heated space that starts up quickly. be.

Structure of the Invention In order to achieve the above object, the present invention provides a floor heating device that has a floor temperature detector that detects the floor temperature and that heats the floor surface to a set floor temperature, and a room temperature detector that detects the room temperature. and is combined with a high-temperature radiant heating device such as an electric stove that heats the room to a set indoor temperature, and calculates the set indoor temperature according to the floor temperature detected by the floor temperature detector, and A control device is provided that calculates the floor surface temperature setting according to the room temperature detected by the detector. According to this configuration, it is possible to create a comfortable heated space that saves energy and starts up quickly.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. FIG. 2 shows the installation state of the heating device in one embodiment of the present invention, where 1 is an electric carpet, 2 is an electric stove, 3 is a floor temperature detector disposed on the electric carpet 1, and 4 is a room temperature sensor. A room temperature detector 5 mounted on the wall calculates a set room temperature according to the floor temperature detected by the bed temperature detector 3, and sets a floor set temperature according to the room temperature detected by the room temperature detector 4. This is a control device that calculates

FIG. 3 shows a control block diagram of the heating device in the above-mentioned embodiment, and the same numbers as in FIG. 2 indicate the same parts, so the explanation thereof will be omitted. 6
7 is a room temperature setting device that calculates the indoor temperature setting according to the bed temperature detected by the bed temperature detector 3, and 7 is a room temperature setting device that compares the signal from the room temperature setting device 6 with the signal from the room temperature detector 4. , is a voltage comparator that sends an ON-FF signal to the electric stove power supply circuit 8. Further, 9 is a bed temperature setting device that calculates a set floor temperature according to the room temperature detected by the room temperature detector 4, and 1o is a signal from the bed temperature setting device 9 and a signal from the bed temperature detector 3. This is a voltage comparator that compares the signal with the signal of the electric carpet and sends an ON-OFF signal to the electric carpet power supply circuit 11.

In the above configuration, the room temperature setting device 6 and the bed temperature setting device 9 are controlled according to the control characteristic curve A shown in FIG.
calculates the indoor temperature setting and floor surface temperature setting, respectively. Then, after heating starts, as the room temperature ta and the floor temperature J rise, the set indoor temperature becomes the room temperature ta1, the floor set temperature is equal to the floor temperature 1, and the voltage comparators 7 and 10
OFF control signals are sent to the electric stove power supply circuit 8 and the electric carpet power supply circuit 11, respectively. As a result, the room temperature - and the bed temperature tl are controlled on the control characteristic curve A shown in FIG. That is,
According to this configuration, the lack of performance of the electric carpet is overcome without losing the comfort of the electric carpet, and comfortable control characteristics as shown in FIG. 4 are exhibited. In addition, as is clear from Figure 1, the temperature of an electric stove, which is a high-temperature radiant heating device, rises quickly, so when the room temperature drops due to a disturbance at the beginning of heating or during heating, the occupant's sense of warmth quickly rises. Effects of the Invention As is clear from the above description, the heating device of the present invention combines a floor heating device with a high-temperature radiant heating device such as an electric stove, and also uses the floor temperature detected by the floor temperature detector. We installed a control device that calculates the indoor temperature setting according to the room temperature detected by the room temperature detector, and also calculates the floor surface temperature setting according to the room temperature detected by the room temperature detector, so that when the room temperature drops due to disturbances during the initial stage of heating or during heating, the occupant's sense of warmth can be improved. It can be started up quickly, and as a result, it can overcome the lack of capacity of floor heating without sacrificing the energy-saving properties and comfort of floor heating, making it possible to perform heating quickly.
