Description

[Detailed Description of the Invention] Industrial Application Field This invention is a hot water floor heating system that heats the floor by flowing hot water heated using residual heat from a stove through a circulation passage provided in a floor panel, etc. Regarding equipment.

BACKGROUND ART A known hot water floor heating system of this type is one in which water stored in a water storage tank is heated by residual heat from a stove and then circulated to the floor surface using a pump.

Problems to be Solved by the Invention However, in the hot water type floor heating system, it takes a long time for the circulating water to reach a temperature suitable for heating, so even when the stove is lit, the floor panel does not heat up immediately. .

Furthermore, there is a problem in that, for example, in early winter or early spring, it is not possible to heat only the floor panel without igniting the heat source of the stove, that is, it is not possible to perform heating only by the floor panel.

This invention was made in order to solve the above-mentioned conventional problems.It is possible to warm up the floor panel in a relatively short time after igniting the heat source, and it is possible to use only the floor panel regardless of the heat source of the stove. The purpose of the present invention is to provide a hot water type floor heating system that can perform heating using water.

Means for Solving the Problems The hot water type floor heating device of the present invention has a circulation passage that communicates the discharge port and suction port of the pump with a heat receiver, a floor panel, and a water storage tank extending from the discharge port side to the suction port side. In a hot water floor heating system that heats the floor panel by circulating hot water received from a heat source of a stove disposed near the heat receiver in sequence, the pump in the circulation path a heating tank interposed between the heating tank and the heat receiver and provided with a heating means; a first level sensor for detecting the water level of the heating tank; and a second level sensor for detecting the water level of the water storage tank. and a time switch that controls on/off the heating means and the pump, and a temperature sensor that detects the water temperature in the heating tank, and when the water temperature in the heating tank reaches a set temperature or higher, the temperature sensor The heating means is turned off based on the detection signals from the first and second level sensors when at least one of the water surface levels of the heating tank and the water storage tank reaches a set level or below. A controller is provided for extinguishing the heat source of the stove.

Effects In the present invention, the heating means is turned on when the set time of the time switch has elapsed, thereby heating the water in the heating tank and driving the pump. Subsequently, when the heat source is ignited and the water temperature reaches the set temperature, the heating means is turned off. and,
When the heat source is ignited, that is, when the time switch is set during heating by the heat source and the pump stops, and when the time switch is set, that is, when the heat source is ignited when the pump is stopped, water will not circulate. Therefore, the first level sensor detects a state in which heat is locally received in the heat receiver, hot water in the heat receiver evaporates, and steam flows to the heating tank side where the passage resistance is small, and the heat source is extinguished.

Further, when the water level in the water storage tank falls below a set level, the second level sensor detects this and extinguishes the heat source to prevent dry cooking.

Embodiment FIG. 1 is an explanatory diagram showing the configuration of an embodiment of a hot water floor heating device according to the present invention, and in the figure, 1
is a pump, and its discharge port 10 and suction port 11 are communicated by a circulation passage 2, and in this circulation passage 2, a heat receiver 3, a floor panel 4, and a water storage are connected from the discharge port 10 side to the suction port 11 side of the pump 1. Tanks 5 are successively provided. The heat receiver 3 is constituted by a so-called heat exchanger, and is arranged near the heat source 6 of, for example, an oil stove, and is constituted by a meandering pipe equipped with a large number of fins. The floor panel 4 is formed by attaching urethane foam as a heat insulating material from the bottom to metal pipes arranged in a meandering manner, and a metal plate such as aluminum from the top. laid on the surface.

A heating tank 7 is interposed between the pump 1 and the heat receiver 3, and is provided with a heating means 8 consisting of an electric heater, and a first level sensor 9 for detecting the water surface level.
A is interposed. Further, the water storage tank 5 is also provided with a second level sensor 9B for detecting the water surface level. Reference numeral 20 denotes a controller for controlling the operation of this hot water type floor heating system, which turns off the heating means 8 based on a signal from a temperature sensor 7A that detects the water temperature in the heating tank 7, and also turns off the heating means 8 based on the signal from the temperature sensor 7A that detects the water temperature in the heating tank 7. Control is performed to extinguish the heat source 6 based on the detection signals from 9A and 9B.

A time switch 21 controls the heating means 7 and the pump 1 on and off. Reference numeral 22 is an ignition lever attached to the front of the stove body (not shown).

Next, the operation of the above configuration will be explained.

First, plug in the outlet not shown in the diagram. As a result, the water surface level detection signal from the second level sensor 9B is input to the controller 20, and if the water amount is secured, the operation described below will be performed. If a water leak or the like occurs in the circulation passage 2 and a water level shortage is detected, resulting in a drop in the water surface level, a buzzer or the like (not shown) will emit an alarm sound. Therefore, in this case, water is supplied to the water storage tank 5 to ensure a predetermined amount of water. This prevents empty cooking.

Under normal conditions where the amount of water is secured,
When the ignition lever 20 is pressed down, the power is turned on and a well-known ignition mechanism is operated to ignite the heat source 6, and the pump 1 starts to drive and the heating means 8 is turned on.

The water circulating through the circulation passage 2 by the pump 1 is rapidly warmed by the synergistic effect of receiving heat radiation from the heat source 6 via the heat receiver 3 and being heated by the heating means 8, thereby performing floor heating.

Note that when the circulating water temperature reaches, for example, 60° C., the controller 20 turns off the heating means 8 based on the detection signal of the temperature sensor 7A. Therefore, from now on, heat source 6
The circulating water is heated by

When the ignition lever 22 is returned to the upper position, the power is turned off and the pump 1 is stopped.

On the other hand, after pushing down the ignition lever 22 from the upper OFF position to the middle position, the time switch is set to a predetermined time value. When this set time has elapsed, the pump 1 is driven and the heating means 8 is turned on. Therefore, the circulating water heated by the heating means 8 warms the floor panel 4.

Therefore, by setting the time switch 21 to start at an appropriate time before waking up,
A state is obtained in which only the floor panel 4 is already warmed when waking up.

Furthermore, by simply holding the ignition lever 22 in the middle position, the pump 1 can be driven and the heating means 8 can be turned on, so that heating can be performed only by the floor panel 4 in early winter or early spring.

On the other hand, if the heat source 6 is used for heating, if the time switch 21 is set by mistake, or if the heat source 6 is ignited when the time switch 21 is set, the pump 1 will not be driven and the heat will not be received. The water in the vessel 3 is locally heated and expands and vaporizes. Since the meandering pipes are arranged relatively densely in the floor panel 4, the passage resistance on the downstream side of the heat receiver 3 is slightly larger than on the upstream side. Therefore, the steam generated in the heat receiver 3 is transferred to the upstream side where the passage resistance is low, that is, the heating tank 7.
Run to the side. In this state, the first level sensor 9A
This detection signal is input to the controller 20 to turn off the power and extinguish the heat source 6.

Therefore, problems such as the spouting of steam from the connecting portion of the circulation passage 2 and the generation of abnormal noise can be prevented.

Effects of the Invention As explained above, according to the present invention, the water can be heated by the synergistic effect of the heat source and the heating means, so that the water temperature rises steeply, and the floor surface is heated in a relatively short time after the heat source is ignited. Panels can be heated. Furthermore, since the floor panel can be warmed by operating the heating means regardless of the heat source, heating can be performed using only the floor panel in early winter or early spring.

Furthermore, it has the effect of preventing the ejection of steam and the generation of abnormal noises caused by erroneous operation, and also preventing the phenomenon of dry cooking.
