  By the way, in recent residences, many dining kitchens are constructed with a dining room and kitchen as one room. When floor heating is laid in such a dining kitchen, cooking facilities such as sinks and gas stands are installed. Since the cooking table including it is installed, the above-mentioned heat radiation panel is usually installed only on the floor of the dining room. Therefore, in the kitchen part, there is a problem that the heating under the feet is insufficient in the cold season, and it is desired to install the above-described heat radiation panel also on the floor of the kitchen part.

  However, since the conventional heat radiation panel is designed for a living room and has a large heat radiation amount (output), when it is laid on the floor of the kitchen part, a gas stand may be used. There is a problem that the temperature rises too much, causing discomfort. In addition, there is a problem that it requires a considerable construction cost by laying a similar heat radiating panel in the kitchen part in addition to the cafeteria part, and there is also a problem that the heat source device for hot water supply is enlarged.

  The present invention has been made as a result of various studies to construct an effective floor heating in a dining kitchen, and an object of the present invention is a floor heating panel laid in a dining kitchen, and a kitchen portion together with a canteen portion. It is another object of the present invention to provide a floor heating panel that can provide a comfortable heating effect and can be constructed at a lower construction cost.

  In order to solve the above problems, in the present invention, at least one main heat radiating panel is disposed in the dining room portion, and a plurality of auxiliary heat radiating panels having a smaller area than the main heat radiating panel are disposed in the kitchen portion. In the auxiliary heat dissipation panel, the water flow pipe of the auxiliary heat dissipation panel is connected in series to the downstream side of the heat dissipation pipe of the heat dissipation panel so that the hot water supplied from the heat source device flows sequentially from the main heat dissipation panel to the auxiliary heat dissipation panel. Excessive heat dissipation was suppressed, and the heating effect was demonstrated in a balanced manner in the dining room and kitchen area.

  That is, the gist of the present invention is a floor heating panel laid on the floor of a dining kitchen in which a dining room and a kitchen are configured as a single room, and the dining room part and the kitchen part are partitioned by a cooking table. Including at least one main heat dissipating panel, and a plurality of auxiliary heat dissipating panels formed in a kitchen area that is smaller in area than the main heat dissipating panel, Each of the thin plate-like foamed resin moldings is configured by arranging a water flow pipe on the front side, and is configured so that hot water can be circulated through the water flow pipe by a forward pipe and a return pipe as communication pipes extended from the heat source device. In addition, the water flow pipe of the auxiliary heat dissipation panel is connected in series to the downstream side of the water flow pipe of the main heat dissipation panel, and the hot water supplied from the heat source device flows sequentially from the main heat dissipation panel to the auxiliary heat dissipation panel. It is configured lies in the floor heating panel, wherein the.

  According to the floor heating panel according to the present invention, the hot water supplied from the heat source device sequentially flows from the main heat radiating panel to the auxiliary heat radiating panel, sufficiently dissipates heat in the main heat radiating panel, and suppresses excessive heat dissipation in the auxiliary heat radiating panel. Therefore, even when a gas stand is used, there is no uncomfortable feeling in the kitchen part, and the heating effect can be exerted in a balanced manner in the dining room part and the kitchen part, so that a comfortable heating effect can be obtained throughout the room. Moreover, it can be constructed simply by combining a main heat radiation panel similar to the conventional one with a small auxiliary heat radiation panel, and a floor heating for a dining kitchen can be constructed at a lower cost.
