The conventional condenser 58 cools the atmospheric gas A by the suction air C of the cooling fan 61 provided on the side surface thereof.

[0006]

However, since the condenser 58 of the conventional garbage disposer 51 is of an air-cooled type, the heat energy released from the atmospheric gas A by the condenser 58 is exhausted as warm air to the outside air. , It was difficult to use it effectively. In addition, if the garbage disposer 51 is installed indoors, the room temperature rises due to the warm air, which is not very preferable.

Further, in the air cooling system, the cooling efficiency is affected by the outside air temperature, so that the cooling efficiency is reduced in summer and the capacity may be insufficient.

Accordingly, the present invention has been devised to solve the above-mentioned problem. The object of the present invention is to make it possible to effectively use heat energy, not to be affected by the outside air temperature, and to further influence the outside environment. An object of the present invention is to provide a garbage disposer that does not give the garbage.

The water jacket 31 comprises a box 34 that covers the condenser 8 in a watertight manner. In the box 34, openings 35 through which the circulation path 7 penetrates in a watertight manner are formed at two locations on the upstream side and the downstream side of the atmospheric gas A, respectively.

At the upper end of the water jacket 31, a cooling water inlet 36 and a cooling water outlet 32 are formed. The cooling water inlet 36 is connected to the water supply. Cooling water outlet 3

In addition to the control method described above, a temperature sensor for detecting the steam G temperature is provided at the outlet of the condenser 8, and the opening and closing valve 39 is controlled to open and close so that the steam G temperature becomes substantially constant. It may be something.

According to this, the cooling water heated to a substantially constant temperature can be supplied to a water heater or the like.

The on-off valve 39 is proportional to the steam G temperature.
May be controlled so as to increase or decrease the flow rate of the cooling water by adjusting the opening degree of the cooling water.

Next, the operation of the garbage disposer according to the present invention will be described.

First, raw garbage is put into the processing tank 2, and the garbage is crushed while being stirred by the rotation of the stirring blades 3, and is heated by the heat of the heater 16 to evaporate the water. This reduces the weight and volume of the garbage.

The atmospheric gas A in the processing tank 2 is supplied to the suction pipe 19
Is sucked into the condenser 8 through. When the temperature of the atmospheric gas A exceeds 60 ° C., the temperature sensor 41 detects the temperature and sends a signal to the controller 43, which opens the on-off valve 39. Thereby, the cooling water flows into the water jacket 31, and the atmosphere gas A is cooled.

At this time, the cooling water once flows downward along the partition plate 37, passes through the gap between the lower end of the partition plate 37 and the bottom surface of the water jacket 31, flows upward, and flows through the cooling water outlet 32. , It can circulate in the water jacket 31 and come into contact with the pipe 21 and the radiating fins 22 in many areas. Therefore, thermal energy can be efficiently transferred from the atmospheric gas A to the cooling water through the pipe 21 and the radiation fins 22.

The cooling water, which has been transferred by the heat energy and heated, flows through a hot water flow path 33 to a hot water supply side such as a water heater, where it is further heated or used as it is as it is.

As described above, by making the condenser 8 water-cooled and flowing the cooling water to the hot water supply side, about 70% of the energy consumed by the heater 16 can be recovered as hot water, and its effective utilization can be achieved. Can be achieved.

According to the present invention, as in the prior art,
Since no hot air is emitted, even if the garbage disposer 1 is installed in the room, the room temperature does not rise and the external environment is not affected.

Further, since tap water is used as the cooling water, the temperature of the cooling water is not so high even if the outside air temperature is high, and the atmosphere gas A can be appropriately cooled even in summer. There is no shortage of abilities.
