Description

  The present invention relates to a heating device.

  2. Description of the Related Art Conventionally, there is known a heating device that can perform heating only by a stove and combined heating by a stove and hot water heating (see, for example, Patent Document 1). In this heating device, the heating of the stove alone or the combined heating by the stove and the hot water heating is performed by switching the flow of the combustion gas with a damper or the like.

  In hot water heating, the circulating fluid stored in a tank provided in the casing of the heating equipment is circulated by a circulation pump, and the circulating fluid heated by the heat exchanger for hot water is supplied to a radiator such as a simple floor heater. It is done by doing.

JP2013-12496A

  In the heating device described in Patent Document 1, the circulating fluid in the tank gradually evaporates while the heating operation is performed. For this reason, an injection part for replenishing the circulating fluid in the tank is provided in the upper part of the tank.

In order to always ascertain the remaining amount of circulating fluid in the tank in such a heating device, it is conceivable to attach a liquid level meter for detecting the level of circulating fluid in the tank to the upper surface of the tank.
However, in this case, if the replenishment amount of the circulating fluid is too large, the circulating fluid may overflow from the portion where the liquid level gauge is attached. The circulating fluid overflowing from the tank flows down along the surface of the tank. Here, since the tank is disposed in a relatively narrow space within the casing of the heating device, it may be difficult to perform a process such as cleaning on the overflowed circulating fluid.

  The present invention has been made in view of the above circumstances, and when a liquid level gauge is attached to a tank that stores the circulating liquid used for hot water heating, the circulating fluid is started from the portion where the liquid level gauge is attached. It is an object of the present invention to provide a heating device that can easily process the overflowing circulating fluid even when the overflowing.

  In order to solve the above problems, the present invention provides a burner for burning fuel, a heat exchanger for hot water heated by combustion gas of the burner, and a heat exchanger for connecting the hot water heat exchanger to a radiator. A heating device comprising a circulating pipe and a tank installed in the pipe, wherein the tank detects a position of a container main body for storing the circulating liquid and a level of the circulating liquid in the container main body. A liquid level gauge, and the container body has an attachment hole provided on an upper surface of the container body and to which the liquid level gauge is attached, and a wall portion standing on the upper surface of the container body. And the said tank is arrange | positioned inside the door provided in the housing | casing of the said heating apparatus so that opening and closing is possible, The said attachment hole is arrange | positioned at the said door side of the said wall part, It is characterized by the above-mentioned. .

In such a configuration, even if the circulating fluid overflows from the portion where the liquid level meter is attached by supplying too much circulating fluid to the tank, the overflowing circulating fluid is erected on the upper surface of the container body. Dammed by the wall. For this reason, the overflowing circulating fluid is suppressed from flowing down to the opposite side of the tank door, that is, the rear side of the tank, which is difficult to perform processing such as cleaning.
Therefore, even if the circulating fluid overflows from the part where the liquid level gauge is attached, the overflowing circulating fluid flows down to the tank door side, that is, the front side of the tank. It becomes easy.
That is, according to the present invention, when a liquid level gauge is attached to a tank that stores the circulating liquid used for hot water heating, even if the circulating liquid overflows from the portion where the liquid level gauge is attached, it overflows. It is possible to provide a heating device that can easily process the circulating fluid that has come out.

  In the heating apparatus, it is preferable that the wall portion is located on a parting line when the container body is molded.

  In such a configuration, a flange-like bulge generated on the mold mating surface when the container body is molded using a mold can be configured as the wall portion of the present invention. For this reason, a wall part can be formed easily, suppressing a cost increase.

  In the heating device, the liquid level gauge has a fixing portion fixed to the mounting hole, and the fixing portion has an overflow port through which circulating fluid overflows from the container body. Preferably it is.

  In such a configuration, when the circulating fluid is excessively supplied to the tank, the circulating fluid overflows from the overflow port of the fixed portion, for example, from other places such as the injection portion of the circulating fluid into the tank. It will not overflow. Therefore, the supply amount of the circulating fluid to the tank can be suppressed. Further, when the circulating fluid overflows from the tank, it overflows from the overflow port of the fixed portion, and the overflowing circulating fluid can be reliably dammed by the wall portion and flowed down to the front side of the tank.

  In the heating device, it is preferable that the overflow port is disposed on the door side of the fixed portion.

  In such a configuration, the circulating fluid overflowing from the overflow port can be guided to flow to the tank door side, that is, the front side of the tank. For this reason, it becomes easier to treat the overflowing circulating fluid.

  In the heating device, it is preferable that an electrical component is disposed on the side of the tank opposite to the door.

  In such a configuration, the circulating fluid overflowing from the part where the liquid level gauge is attached flows down to the opposite side of the tank door, that is, the back side of the tank, and the operation of the electrical components such as the motor of the circulation pump is performed. It is possible to prevent troubles.

  According to the present invention, when a liquid level gauge is attached to a tank that stores the circulating liquid used for hot water heating, even when the circulating liquid overflows from the part where the liquid level gauge is attached, A heating device that can easily process the circulating fluid can be provided.
