Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to heating cooking utensils, and more specifically, it concerns the cooking surface during heating. Heating cooking utensils such as hot plates that can collect oil from the oil smoke generated by Regarding.

0002

[Conventional technology]

Hot plates and other devices that allow you to easily heat and cook meat, etc. at the dining table. Although thermal cooking utensils are becoming more common, oil smoke is produced when cooking indoors with insufficient ventilation. There was a problem that the oil and odor would adhere to the ceiling, walls, etc. This measure There is a way to install an air purifier on the dining table, but large ones may interfere with the meal. This is because small ones cannot absorb the rapidly rising oil smoke. Oil can be separated and recovered from oil smoke and can be used without worrying about indoor contamination. There was a desire to develop heating cooking utensils that could do this.

0003

[Problem that the idea aims to solve]

This invention solves the above-mentioned drawbacks and collects oil from the oil smoke generated during cooking, thereby reducing indoor pollution. The purpose of the present invention is to provide a heating cooking utensil that can prevent staining.

0004

[Means to solve the problem]

In order to solve the above problems, the present invention has developed a heating cooking appliance body with the top surface as the cooking surface. It is located above the cooking surface, with an exhaust port in the center of the top and an open bottom surface. A smoke collection tube with an oil gutter equipped with an oil drain on the inner side of the periphery of the opening; a plurality of struts connecting the main body; a heat exchanger connected to the exhaust port; Located below the exhaust port, it receives oil dripping from the exhaust port and guides the oil to the oil gutter. an oil pan and an oil sump located below the oil outlet to receive oil dripping from the oil outlet. A heating cooking utensil was constructed. Then, the heat exchanger is connected to an inner cylindrical portion corresponding to the exhaust port. and an outer cylindrical part provided on the outer periphery of the inner cylindrical part. Each has a fin. Further, a blower was provided at the exhaust port.

[0005]

[Effect]

According to the above configuration, the oil smoke generated from the cooking surface becomes an upward air current and is directed upward. reaches the opening of the smoke collection tube. The smoke collection tube forms a ventilation path from the opening to the exhaust port. , a heat exchanger that sucks oil smoke into the smoke collection pipe due to the chimney effect and connects it to the exhaust port. Sends oil smoke into the inner cylinder of the exchanger. The fins inside the inner cylinder cool the passing oil smoke and The fins on the outside of the cylinder cool the inner cylinder, etc., which are heated by heat exchange with high-temperature oil smoke. . The cooled oil smoke condenses and falls into the oil pan and is led to the oil gutter or inside the smoke collection pipe. The oil is guided to the oil gutter, and is collected in the oil sump via the oil outlet.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 to 3 , 1 is a heating cooking appliance body that houses a heater 2 therein, and has a cooking surface 3 on a stepped portion of the top surface. There is. Reference numeral 4 denotes a substantially umbrella-shaped smoke collection tube provided above the cooking surface 3 with a space 18 in between. , an exhaust port 5 is provided in the center of the upper part and the bottom surface is opened, and oil is provided inside the periphery of the opening 6. Gutter 7 is installed around it. The oil gutter 7 is inclined so that the oil flows in one direction. It is equipped with an oil drain port 8 at the bottom. 9 connects the smoke collection pipe 4 and the main body 1. A plurality of pillars having lower ends outside the main body 1 and upper ends outside the smoke collecting pipe 4, respectively. It is fixed with screws. 10 is a heat exchanger that can be freely ventilated and is connected to the exhaust port 5. In the exchanger, an inner cylindrical part 11 corresponding to the exhaust port 5 and an outer periphery of the inner cylindrical part 11 are integrally installed. The inner cylinder part 11 (inside the inner cylinder) has fine fins. 13. The outer cylinder portion 12 (outside the inner cylinder) is provided with coarse fins 14, respectively. 15 is located below the exhaust port 5, and receives the oil dripping from the exhaust port 5 and flows into the oil gutter 7. An oil receiver that guides oil to the pipe, and is integrally attached to the inside of the smoke collection pipe 4 via a plurality of supports 16. I'm being kicked. 17 is removably screwed onto the oil drain port 8, and is located below the oil drain port 8. This is an oil sump to catch dripping oil.

[0007] With the above configuration, the operation of this heating cooking appliance will be explained next. First of all, The oily smoke generated from the cooking surface 3 becomes an updraft and flows through the opening of the smoke collection pipe 4 located above. Reach 6. The smoke collection tube 4 forms a ventilation path from the opening 6 to the exhaust port 5, and improves the chimney effect. A heat exchanger that sucks oil smoke into the smoke collection tube 4 and is connected to the exhaust port 5. Oil smoke is sent into the inner cylinder part 11 of 10. The fins 13 of the inner cylinder part 11 prevent the passing oil smoke from passing through. The fins 14 of the outer cylindrical part 12 are heated by heat exchange with the high temperature oil smoke. The cylindrical portion 11 is cooled. The cooled oil smoke condenses, falls into the oil pan 15, and is guided to the oil gutter 7. It is guided to the oil gutter 7 along the inside of the smoke collection pipe 4, and then is drawn to the oil sump via the oil outlet 8. It will be collected on the 17th.

[0008] FIG. 4 shows another embodiment of the present invention, in which a blower 1 is installed above the heat exchanger 10. The configuration is the same as that of the previous embodiment except that 9 is provided. According to this collection The chimney effect of the chimney tube 4 is increased and the diffusion of oil smoke can be prevented, and the heat exchanger 10 cooling power can be increased.

[0009]

[Effect of the idea]

As described above, according to the present invention, the oil smoke generated from the cooking surface is connected to the smoke collection tube above. It can be cooled in a placed heat exchanger and the oil components can be collected by condensation. Therefore, it is possible to prevent oil smoke from adhering to the ceiling, walls, etc. Also, heat exchanger It has a double structure with an inner cylinder part and an outer cylinder part, and a blower is installed on the top of the heat exchanger. In addition to increasing the suction power of oil smoke into the smoke collection tube, the cooling power of the heat exchanger is also increased to circulate the oil. Yield capacity can be increased.
