By maximizing the utilization of the heat source of the waste exhaust gas, the use of heat energy required to heat the water supply for cooking can be reduced, thereby further improving the energy efficiency of the cooking pot, and for the sanitary management of the discharge device. It relates to an exhaust gas exhaust device for a cooker having a hot water supply structure using a new type of waste heat that can prevent damage to various components such as motors and exhaust fans during water cleaning, thereby stably maintaining clean and sanitary conditions of the exhaust device. .

In general, a cooking pot is used where a large amount of food is required, such as a group meal, and cooks a large amount of food at a time.

The cooking pot as described above includes a pot unit (1) in which food to be cooked is contained, a pot housing (3) that surrounds the outer surface of the lower side of the pot section (1) to form a heating and exhaust passage (2), and the pot housing A gas burner (4) provided at the lower part of (3) to heat the bottom of the pot for cooking, and a pot housing (3) so that the exhaust gas discharged through the exhaust passage (2) can be discharged to the outside. It is made of an exhaust hole (5) formed in the.

On the other hand, in the cooking pot, exhaust gas at a high temperature of 300 ° C to 500 ° C is discharged through the exhaust hole 5 during the cooking process, and the exhaust gas discharged as described above rises along the outer surface of the pot housing 3 . It comes into contact with the upper end of the pot (1) and is then released into the air. At this time, the emitted exhaust gas locally heats the upper end of the cooking pot, causing warping deformation, raising the surrounding temperature, and contaminating the surrounding air. In recent years, a cooking pot ventilation induction duct has been developed and used to induce exhaust gas discharged from the cooking pot to the side of the ventilation unit provided on the ceiling.

In order to solve the above problems, in recent years, an exhaust fan is formed inside the exhaust device to forcibly exhaust the exhaust gas generated during cooking. Patent Registration No. 10-1833302 (registration date: 2018) February 22) The pot exhaust device, in the exhaust device for discharging exhaust gas generated from the cooking pot to the hood, is spaced apart from the exhaust gas outlet protruding from the side of the cooking pot, and has an open front. It is made of a fan-shaped frame, and an inner frame spaced apart from the outer surface is formed, and a plurality of diaphragms spaced apart from the inner frame are inclined toward the rear center to collect the exhaust gas toward the rear center. An exhaust inlet comprising an exhaust inlet, and an exhaust communication portion formed of a double pipe having an inner tube having a diameter smaller than an outer tube and made of a communication extending from the center of the rear surface of the exhaust inlet to the upper portion, and the exhaust communication portion is coupled to the upper portion of the inner tube A motor covered with a cap installed between a funnel-shaped exhaust discharge part that widens toward the upper part and a pedestal installed in the center of the exhaust exhaust part and made of a plurality of plates having a predetermined height at the lower part of the exhaust exhaust part and an exhaust fan connected to, wherein a lower diameter of the exhaust outlet is larger than a diameter of an inner tube installed under the exhaust outlet, and an exhaust hole is formed between the pedestals installed with a plurality of plates spaced apart from each other in the center of the exhaust outlet. It is characterized by being

In addition, since the high-temperature exhaust gas is forcibly discharged and removed, when hot water for cooking food or washing a cooking container is required, the use of heat energy is required a lot by using a burner to heat the supplied water. .

On the other hand, in recent years, a technology to use water supply as hot water by using the high-temperature exhaust gas that is thrown away has been developed. The waste heat recovery boiler device equipped with a pot has a double-wall structure composed of an inner wall and an outer wall, a heating space through which waste heat flows is formed between the inner wall and the outer wall, and a cooking space for accommodating food is formed at the upper portion of the inner wall. A rotary pot with a rotating protrusion communicating with the heating space is formed on the outer peripheral surface of the outer wall, a rotating shaft is formed on the outer peripheral surface of the outer wall corresponding to the rotating protrusion, and an insertion hole is formed in the lower part of the outer wall; It is formed in a pair to be spaced apart from each other at a predetermined interval, and the rotary pot support part having a through hole in which the rotary protrusion and the rotary shaft are inserted and coupled on both sides is formed, and the rotary pot is connected to the insertion hole and the pipe by a pipe to heat the lower part of the inner wall A gas burner, a rotary handle connected to the rotary shaft of the rotary pot to rotate the rotary pot, an inlet through which cold water is put in a hollow shape is formed on the upper outer surface, and a waste water outlet through which waste water is discharged is formed on the lower outer surface. There is a hot water outlet formed between the inlet and the wastewater outlet, through which the hot water is discharged, and a storage space for storing the water supplied through the inlet is formed therein. A waste heat passage is formed, and a plurality of heating pipes are formed to circulate the water stored in the storage space at predetermined intervals along the longitudinal direction of the waste heat passage, and a hot water unit is formed, and one end of the rotating protrusion of the rotary pot and It communicates, the other end is in communication with the waste heat passage of the hot water part characterized in that it is composed of a guide tube for guiding the waste heat discharged through the rotary protrusion to the waste heat passage.

However, the waste heat recovery boiler device of the above configuration has a problem in that the boiler device is integrally connected to the rotary pot, so that a lot of cost is incurred in installing the boiler, and there is a problem that it is impossible to install it in an existing installed cooking pot. There are problems in that it is difficult to popularize and the installation cost is high, making it difficult to commercialize.
