持を目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention is a hot water device that utilizes the waste heat of the engine's water jacket and muffler, and is characterized by an early increase in heat recovery efficiency during warm-up operation after engine startup and steady operation after warm-up. The purpose is to prevent the engine from overheating and maintain high heat recovery efficiency.
本発明者は、建物に定置したエンジンの廃熱を利用して

タジャケット及びマフラでの熱回収効率が悪い。First, as shown in Figure @4, the engine E drives the cooling water circulation pump P, and the engine side water channel A leads hot water from the water jacket W of the engine E to a hot water storage tank for heating and temperature supply. We considered a system in which the muffler side channel B, which leads hot water from the cooling water chamber of the muffler M to the hot water storage tank, is placed in parallel, but it took a relatively long time to warm up after starting, and the engine response was poor. In addition, the engine is not warm enough, so incomplete combustion tends to occur, and the heat recovery efficiency in the water jacket and muffler is poor.

By connecting the cooling water in series to the F side of I', L), the cooling water is heated in the cooling water chamber and then supplied to the water jacket, thereby speeding up engine warm-up.

There is a risk that the engine may seize due to overheating.
本発明に上記両システムの各欠点を解消するも。The present invention overcomes each of the drawbacks of both of the above systems.

熱交換を行なう。The muffler 8 consists of an air guide case 21, a catalyst case 22, and a cooling water chamber 9. The high-temperature exhaust gas that enters from the exhaust introduction hole 25 passes through the catalyst case 22 filled with two block-shaped catalysts. The unburned components are re-burned to purify the exhaust gas, and the exhaust gas sent to the cooling water chamber 9 is made higher in temperature. In this way, this high-temperature exhaust gas is divided into a number of thin tubes 24 and discharged from the exhaust pipe 25. However, at this time, heat exchange is performed in the cooling water chamber 9 with the cooling water flowing from the inlet 12 to the outlet 11.

While passing through the tank, heat exchange is performed with the water circulating throughout the tank, and the water is turned into cooling water from the return port 5 and sent to the inlet port 2 of the pump 1.

A thermostatic valve closes the outlet 17 using a built-in water temperature sensor when the temperature of the hot water flowing inside the water jacket reaches 80°C. 20 shall be attached.

At the same time, on-off valves 15 and 16 are provided in the engine side waterway A above the water jacket, the muffler side waterway B below the muffler 1111, and the starting waterway C, respectively. Switchable.

The opening/closing valve 15 of the muffler side waterway B is closed, and the opening/closing valve 16 of the starting waterway C is set to open, so that the cooling water pumped by the pump flows in series from the muffler 8 to the water jacket 7'. In addition, when the engine is in a steady operating condition, the on-off valves 15 of the engine side waterway A and the muffler side waterway B are set to open, and the on-off valve 16 of the starting waterway C is closed, so that the cooling water is muffler 8
and water jacket 7 in parallel to perform heat recovery.

。In the above-mentioned hot water apparatus, the muffler need not be limited to the catalyst-filled type as long as it is provided with a cooling water chamber. The on-off valve provided in each water channel may be switched manually, and a thermostatic valve 20 may also be attached to the outlet 17 of the water jacket to sufficiently warm the circulating cooling water for subsequent heat recovery. Although it is useful for increasing efficiency, there is no problem in omitting this valve and heating the cooling water sequentially.In addition, instead of a hot water storage tank let heat exchange type, water can be directly supplied. The hot water that has been circulated may be transferred to the outside of the system.

染全防止できる。In this way, to explain the present invention in detail, during warm-up operation after starting the engine, the starting side waterway is opened, the cooling water chamber of the muffler and the water jacket of the engine are connected in series, and the cooling water chamber of the muffler is connected in series with the water jacket of the engine. As a result of the circulating water that has undergone thermal IC11 recovery entering the water jacket, the warm-up time of the engine is shortened, and the heat recovery efficiency of the cooling water in the engine is quickly increased by V, and the response performance of the engine is also improved. This eliminates incomplete combustion and completely prevents air pollution caused by exhaust gas.
