Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a smoke evacuation device that separates fats and oils from the air by inertial collision using a baffle plate provided within the main body.

Conventional configuration and its problems As a smoke exhaust system for places that generate oil smoke containing a large amount of oil and fat, such as a range in a commercial kitchen, a baffle plate is used to bend the direction of the oil smoke and remove the oil and fat in the oil smoke. A so-called grease extractor is effective and has recently become popular, which separates the body by inertial collision with the body's internal walls and buckle plate, and then sprays detergent-containing hot water from a spray nozzle installed inside the body to clean the body's internal walls and baffle plate. . Conventional grease extractors are large-sized equipment and expensive, making them unsuitable for household use. As a small, low-cost smoke evacuation device for home use, detergent liquid is stored in a detergent liquid reservoir provided at the bottom of the main unit, and after smoke evacuation is finished, the detergent liquid is repeatedly sprayed on the internal walls and baffle plate of the main unit. A device that cleans the oil and fat adhering to the inner walls and baffle plates is being considered, but since it is cleaned with a detergent solution at room temperature, it is said that if the adhering oil and fat hardens or accumulates over time, it will not be able to clean it sufficiently. There was a problem.

OBJECTS OF THE INVENTION The present invention obviates these conventional drawbacks,
To provide a smoke exhaust device that improves cleaning performance by softening hardened oils and fats adhering to the surface of a baffle plate and at the same time increasing the temperature of a detergent liquid sprayed on the baffle plate.

Structure of the Invention The smoke evacuation device with cleaning device of the present invention includes a cleaning device main body, a plurality of baffle plates provided in the main body, and a spray nozzle for spraying a detergent solution onto the baffle plates and the inner wall of the main body. A heater is installed on the plate to improve the cleaning performance of oils and fats adhering to the panful plate and the inner wall of the main body.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1
is a microwave oven placed on a stand 2, and a main body 3 of the smoke evacuation device is installed above the rear end of the microwave oven 1. Reference numeral 4 denotes an intake port, which sucks oily smoke generated during cooking into the main body of the smoke evacuation device.

Reference numeral 5 denotes a smoke guiding plate, which is provided in the shape of an eave above the intake port 4. An exhaust 77 tank 6 is installed in the upper part of the main body 3 to exhaust purified air from the exhaust lower. Inside the main body 3, there are a plurality of powerful plates 8 that bend the airflow, a plurality of spray nozzles 10 that spray detergent liquid onto the baffle plate 8 and the inner wall of the main body 3, and a detergent liquid that supplies the detergent liquid to the spray nozzles 10. A supply pipe 9 is provided. Furthermore, a heater 11 is installed inside each of the buckle plates 8. This heater 11 may also be installed on the inner wall of the main body 3 if necessary. The bottom of the main body 3 serves as a detergent liquid reservoir 12, and the upper part thereof is a flow port 1 that prevents evaporation of the detergent liquid and returns the detergent liquid flowing down the inner wall of the main body to the detergent liquid reservoir.
It is covered with a partition plate 13 having a diameter of 4.

15 is a drain valve. Reference numeral 16 denotes a thermostat provided in the detergent liquid reservoir 12, which controls the heater 11 installed on the baffle plate 8, and is installed so that its detection part enters the detergent liquid. A detergent tank 17 for supplying detergent solution to the detergent reservoir 12 is provided on the side wall of the main body 3, and a pump 18 for pumping the detergent solution from the detergent reservoir 12 to the detergent solution supply pipe 9.
A box body 19 containing a detergent liquid tank 1Y is attached.
The detergent liquid inside is set in a detergent liquid tank 17 in the box body 19, so that a fixed amount of detergent liquid is supplied to the detergent liquid reservoir 12 of the main body 3.

The front face of the box body 19 is provided with an exhaust fan 6, a pump 18, an operation switch 2o for the heater 11 installed on the baffle plate 8, and a pilot lamp 21.

Next, its operation will be explained. When cooking in the microwave oven 1, when the exhaust fan 6 is activated by the operation switch 20, the oily smoke generated during cooking is sucked into the main body 3 through the intake port 4.
The direction can be bent by the baffle plate 8. However, the oil particles in the oil smoke are separated by inertial collision and adhere to the inner wall surface of the main body 3 and the baffle plate, and purified air is discharged from the exhaust lower. In this way, the oil and fat particles in the oil and fat in the oil smoke are sufficiently captured within the main body 3, but in order to keep the inside of the main body 3 clean at all times, the oil and fat adhering to the inner wall surface of the main body 3 and the baffle plate 8 are cleaned. It's okay if you do it. Here, cleaning inside the main body 3 will be explained. When the operation switch 20 is switched to cleaning, the pump 18 is driven, and at the same time, a voltage is applied to the heater 11 installed on the baffle plate 8. The detergent liquid in the detergent liquid reservoir 12 is supplied to the detergent liquid reservoir 12, the pump 18, the detergent liquid supply pipe 9, the spray nozzle 10. The water is repeatedly sprayed from the spray nozzle 1o along the circulation path on the inner wall of the main body 3 to clean the inside of the main body 3 and the baffle plate 8. At this time, the temperature of the detergent liquid in the detergent liquid reservoir 12 is sensed by the thermostat 16, and when the temperature is less than 40 degrees (a temperature that provides a cleaning effect and is not limited to this temperature), The heater 11 is automatically energized to raise the temperature of the baffle plate 8 to a temperature higher than the temperature at which the fats and oils adhering to the surface are softened (for example, about 40 to 10Q°C). This heating to the baffle plate 8 is performed by a powerful plate. It not only softens the oil and fat attached to the spray nozzle 10 and makes it easier to clean.
This also has the effect of increasing the temperature of the detergent liquid sprayed from the water to clean the baffle plate 8, thereby increasing the cleaning performance of the inner wall of the main body 3 and the baffle plate 8. In addition, if the inner wall of the main body 3 or the baffle plate 8 is left unwashed with oil and fat attached to it, the amount of oil and fat deposited increases and the oil and fat hardens, but even in this case, the baffle plate 8 is heated by a heater 11, and the heat softens the oil and also heats the detergent solution, making it possible to easily wash and remove the deposited and hardened oil. Although explained by placing heaters on each of the baffle plates 8, the baffle plate closest to the intake port 4 is the one where oil and fat are most likely to adhere, so even if the heater is installed only on this baffle plate, it will not be effective in cleaning oil and fat a. can play.

Effects of the Invention As described above, in the smoke exhaust device of the present invention, a heater is disposed on the baffle plate, and the oil and fat attached to the buckle plate surface is softened by the heat of the heater, making it easier to clean. The cleaning performance can be improved by raising the temperature of the detergent solution during repeated spraying, making it extremely useful in practice.
