Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water type floor heating apparatus for circulating hot water to a floor heating panel.

[0002]

2. Description of the Related Art Conventionally, for example, a heat source device installed outdoors and a floor heating panel laid indoors are connected by a hot water pipe, and hot water generated by the heat source device is supplied and circulated to the floor heating panel via the hot water pipe. Therefore, a hot water type floor heating device (hereinafter, simply referred to as floor heating device) for heating a room to a desired temperature is known.

In this type of floor heating system, an opening / closing valve is provided in the hot water pipe to control opening / closing of the opening / closing valve periodically. Then, as shown in FIG. 5, the heating capacity is changed by changing the open / close ratio of the open / close valve, and control is performed so as to maintain a stable room temperature with little fluctuation with respect to the set temperature.

By the way, at the time of starting the operation of the floor heating device, it takes time to warm up the water because all the water contained in the hot water pipe, the floor heating panel and the heat source unit is cold. . For this reason, the user may feel uncomfortable because the time it takes for the room temperature to reach the set temperature (rise time) is long and it does not warm up easily.

Therefore, at the time of starting the operation, there is a model in which the heating capacity is increased as compared with the normal operation and the rising operation is performed for a certain period of time. This shortens the start-up time and reduces discomfort at the start of operation.

[0006]

However, in the case of a model in which the heat source unit can be connected to a plurality of different hot water radiators (air conditioners, floor heating panels, etc.), the heat source unit is a plurality of hot water radiators. It is designed so that the hot water temperature can be generated in several stages corresponding to the required hot water temperature. For example, when an air conditioner and a floor heating panel are connected to a heat source device, the hot water temperature is 80 ° C. when operating only the air conditioner, and the hot water temperature is 60 ° C. when operating only the floor heating panel, and the air conditioner is at the same time. And when operating the underfloor heating panel,
It is generated by setting the hot water temperature to 80 ° C.

Therefore, when the rising operation of the floor heating panel is carried out, it depends on the set hot water temperature,
There was a problem that proper start-up operation could not be performed.

The present invention has been made in view of the above-mentioned conventional problems, and provides a hot water type floor heating apparatus which performs an appropriate start-up operation according to the temperature of hot water supplied from a heat source machine. With the goal.

At the time of starting, the controller is provided with a control device that performs a start-up operation in which the on-off valve is continuously opened to operate, and determines the start-up operation time according to the detected hot water temperature.

According to a second aspect of the present invention, there is provided a floor heating panel and a heat source device capable of supplying hot water via a hot water pipe connected to the floor heating panel through an on-off valve and setting the hot water temperature in several stages. In a hot water type floor heating apparatus that controls the room temperature by periodically opening and closing the on-off valve, there is a plurality of modes for operating by changing the opening time per cycle of the on-off valve. A predetermined time of rising operation is set for each mode, and a controller for controlling the rising operation time to determine the rising operation time from each of the predetermined times and the temperature difference between the room temperature and the set temperature is provided. apparatus.

According to a third aspect of the present invention, in the hot water floor heating apparatus according to the first or second aspect, the rising operation is performed by operating an operation switch for starting the operation of the hot water floor heating apparatus. It is characterized by

It has a display unit 22 for displaying the displayed contents and room temperature and the like, and the room temperature sensor 9.

The operation of the floor heating device 1 is started by pressing the switch 14 once, and the operation of the operation on / off switch 14 is stopped by pressing it again. The mode selector switch 15 has a heating capacity of strong / medium / weak
Can be set to automatic mode. When set to automatic, it automatically switches to strong / medium / weak operation mode depending on the difference between the room temperature and the set temperature.

Next, the operation of the floor heating system during normal operation will be described.

In FIG. 1, the hot water heated in the pipe-shaped heat exchanger 3 by the combustion of the combustion device 5 is a circulation pump P.
