[0001]

[Industrial applications]

 The present invention relates to a heating device such as a stove having a built-in floor heating function for heating from the floor of a room.

[0002]

[Prior Art]

 In the conventional type of this type, although floor heating and indoor heating are performed at the same time, the combustion amount control of the combustion burner detects the detected room temperature and room temperature detected by a room temperature sensor. The temperature was controlled so as to keep the room temperature at the set room temperature while observing the deviation from the set room temperature set by the setting means.

[0003]

[Problems to be solved by the device]

 By the way, in this conventional type, since the floor heating temperature is not taken into consideration in the combustion amount control, the room temperature rises immediately depending on the installation conditions such as the length of floor heating piping and the number of floor heating panels installed. Therefore, the combustion amount is suppressed, so that the floor heating temperature does not rise at all, or conversely, the floor heating temperature is too high, but the combustion amount is maximum. It had a defect such as.

[0004]

[Means for solving problems]

 This invention focuses on this point and solves the above-mentioned drawbacks. In particular, the structure is provided with a stove heat exchanger heated by the combustion heat of a combustion burner and a floor warming heat exchanger. A storage tank, a circulation pump, and a floor heating panel laid on the floor are connected to the heating heat exchanger to perform floor heating by circulating the heat medium, and heat between the stove heat exchanger and room air. In the case of indoor heating by replacement, the combustion control circuit that controls the combustion amount of the combustion burner has a room temperature that calculates the deviation between the room temperature detected by the room temperature sensor and the room temperature set by the room temperature setting means. The control circuit is connected to a floor temperature sensor that detects the floor heating temperature and a floor temperature control circuit that calculates the deviation between the floor temperature setting means and the floor temperature set by the floor temperature setting means. From the normal room temperature control state by the room temperature control circuit to the floor temperature control state by the floor temperature control circuit Those having a priority switching means for switching.

[0005]

[Action]

 In an operating state in which both floor heating and stove heating are used, the room temperature control circuit 25 normally detects the detected room temperature Ta detected by the room temperature sensor 19 and the set room temperature T set by the room temperature setting means 26. The temperature is kept at the set temperature T by controlling the combustion control circuit 23 according to the deviation and controlling the combustion amount of the combustion burner 1 according to this deviation. The equipment heats the floor heating heat exchanger 8 by the combustion heat of the combustion burner 1 so that the heat medium inside the floor heating heat exchanger 8 → storage tank 11 → circulation pump 15 → floor heating It circulates from the panel 16 to the floor heating heat exchanger 8 to perform floor heating. In the normal control state as described above, this floor heating is a room temperature priority control in which the combustion amount is controlled according to the room temperature. Floor temperature control is not performed, and the room temperature is prioritized and controlled to obtain a good room temperature condition. .

Next, by pressing the floor warming priority switch 21, a signal is input to the priority switching means 29, the control signal from the room temperature control circuit 25 is canceled, and the floor warming priority control circuit 27 switches to the floor temperature control circuit 27. The bed temperature Ty detected by the temperature sensor-20 and the bed temperature Tu set by the bed temperature setting means 28 are compared and calculated, and the combustion control circuit 23 is controlled by this control signal, so that the combustion amount of the combustion burner 1 becomes the bed temperature. The floor temperature is prioritized so that the desired bed temperature can always be obtained without the floor temperature being too low or too high.

[0007] Therefore, it is possible to control whether room temperature or floor temperature is prioritized according to the preference of the user, which is convenient for use, and the room temperature is rapidly controlled by the room temperature control at the start of heating. After raising the temperature, it is possible to switch to floor temperature control to achieve ideal heating of head cold foot heat. The optimum temperature control can be easily selected according to the change, and the comfort of this type of floor heating built-in heating system can be further improved.

A floor temperature sensor 20 that is provided and detects the floor heating temperature by detecting the heat medium temperature, and a floor heating priority switch that selects whether the combustion amount control of the combustion burner 1 is controlled by room temperature or floor temperature. 21 and the like are connected. Next, the control circuit 18 will be described with reference to the block diagram of FIG. 2. A micro computer 22 (hereinafter referred to as a microcomputer) including a program circuit and a combustion control circuit 23 on the stove side controlled by the micro computer 22. And a floor heating control circuit 24 on the floor heating side.

Reference numeral 25 is a room temperature control circuit in the microcomputer 22, which inputs the detected room temperature Ta detected by the room temperature sensor 19 and the set room temperature T freely set by the room temperature setting means 26, and compares and calculates both. By outputting this deviation value as a control signal to the combustion control circuit 23, combustion control according to room temperature is performed.

Reference numeral 27 denotes a floor temperature control circuit also provided in the microcomputer 22, which includes a detected bed temperature Ty detected by the floor temperature sensor-20 and a set bed temperature Tu freely set by the floor temperature setting means 28.

The detected room temperature Ta detected by −19 and the set temperature T of the room temperature setting means 26 are compared and calculated by the room temperature control circuit 25, and this deviation value is input to the priority switching means 29 as a control signal, whereby the priority switching means In 29, since the floor warming priority switch 21 is not pressed, the above control signal is directly output to the combustion control circuit 23, the driving of the electromagnetic pump 3 and the combustion fan 4 is started, and the room temperature Ta is set close to the set room temperature T. In order to achieve this, the combustion amount is controlled in 6 stages (step 32).

Then, the combustion heat generated by this combustion and the indoor air from the convection fan 6 are heat-exchanged with each other by the heat exchanger 7, and the room is satisfactorily heated by warm air heating with a stove. Since floor heating operation is also used and the floor heating damper 9 is opened, the heat medium heated by the floor heating heat exchanger 8 circulates in the floor heating circulation circuit and is radiated by the floor heating panel 16. By doing so, the floor heating is performed, but since the floor warming temperature at this time is controlled by the above step 32, the combustion amount of the combustion burner 1 is not considered at all, and the stove is not considered. The indoor heating by is given priority.

The room temperature control is not performed at this time, and when the floor warming priority switch 21 is released, the room temperature control operation is resumed.

Next, the routine proceeds to step 35, where it is judged whether the detected bed temperature Ty has risen to 3.5 ° C. or higher by the set bed temperature Tu, the process returns to step 32 with NO, the process proceeds to step 36 with YES, and the detected room temperature Ta is It is judged whether or not the temperature exceeds the set temperature T, and if YES, the process proceeds to step 37, and in order to prevent the room temperature from further rising, the stove save is extinguished once and re-ignites automatically if the room temperature falls again. If the fire is extinguished, and if NO, the routine proceeds to step 38, in which only the floor heating that has risen in temperature is stopped and the floor warming control circuit 24 is controlled to automatically switch to the stove independent operation. -9 is closed, and at this time, the circulation pump 15 is continuously driven because the floor temperature is detected. When the floor temperature Ty decreases, the floor heating damper-9 is opened again and the floor heating is not performed. Resuming or returning to step 32 Is.

Accordingly, by providing the floor warming priority switch 21, it is possible to freely select and use which of the room temperature Ta and the floor temperature Ty is controlled for combustion according to the user's preference or installation conditions. Therefore, the convenience of using this type of heating system with a built-in floor heating function can be improved, which is extremely convenient.
