Description

[Detailed explanation of the invention] This invention is a heating system that blows warm air into a room by operating a fan while circulating hot water generated in a boiler through an internal heat exchanger. Related to hot water circulation type heating radiator.

Specifically, in such a radiator, in order to prevent the fan from being activated before the circulating hot water temperature reaches the desired heating temperature, such as at the beginning of operation, cold air is blown out, causing discomfort. The present invention relates to an improvement in the mounting form of a temperature switch used for controlling fan operation.

Conventionally, the above-mentioned temperature switch was installed only on either the hot water inlet pipe or the hot water outlet pipe to the heat exchanger, but this caused the following inconveniences when constructing the piping on site. It was happening.

In other words, at the site, the inlet pipe (low temperature side) and the back (high temperature side) of the boiler were incorrectly connected to the predetermined inlet pipe (high temperature side) and back (low temperature side) of the radiator. If this happens, the hot water will flow out of the radiator's original inlet pipe and flow into the mountain's back.

Even in this case, the basic function as a radiator is still maintained, but the operation of the temperature switch will be inconsistent.

In other words, the switch turns on and the fan starts blowing cold air even though the hot water is at a low temperature that should normally keep the switch off, or vice versa. This is inconvenient because it remains in the OFF state even though the temperature has exceeded the temperature, and blowing out of warm air is delayed.

In view of this point, the present invention aims to solve the above-mentioned disadvantages by devising the mounting form of the temperature switch.

The configuration according to the gist of the present invention is to install a plate with good thermal conductivity between the hot water inlet pipe on the side that supplies wet water to the heat exchanger and the hot water outlet pipe from the heat exchanger. The installation is a hot water circulation type heating radiator with a temperature switch for controlling fan operation attached to the central part of the board in the installation direction.

In other words, instead of associating the temperature switch for controlling fan operation only with the immigration area or only with the back of the mountain,
Good thermal conductivity mounting is connected to both the entrance pipe and the back of the mountain by the plate, and by attaching it to the center of the board, it is equally connected to both the entrance pipe and the back of the mountain.

In other words, it is designed to detect the average temperature between the temperature at the entrance tube and the temperature at the back of the mountain.

Therefore, even if you accidentally connect the inlet pipe and back of the radiator to the back of the radiator and the inlet pipe and back of the boiler to the back of the radiator during piping construction on site, the state of temperature detection by the temperature switch will be correct. There is no substantial difference from the case of piping connection.

In other words, the effect of the present invention is that the temperature switch can be operated under the normal operating characteristics even if the piping is incorrectly connected, thereby avoiding the conventional inconveniences such as the delay in blowing out cold air or blowing out warm air. This means that it is possible to do so.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

As shown in FIG. 1, a hot water inlet pipe 2 and a hot water outlet pipe from the heat exchanger 1 supply hot water to a fin tube type heat exchanger 1 installed opposite to an indoor air convection fan 6. As shown in FIG. 3, a plate 4 made of aluminum or other material having good thermal conductivity is installed between the plate 3 and the plate 4 so as to be removable.

In this installation, the plate 4 is installed between the inlet pipe 2 and the mountain spine 3 outside the area of the airflow caused by the fan 6.

The mounting is done by attaching a temperature switch 5 (for example, a bimetal switch) for controlling the operation of the fan 6 to the center of the plate 4 in the installation direction.

This temperature switch 5 is connected to a second temperature switch via lead wires 7, 7.
As shown in the electric circuit shown in the figure, it is connected in series to the fan 6.

In addition, the mounting means for the plate 4 may be screwed or welded.
