JPS59215530A - Exhaust gas processing device - Google Patents

Abstract

PURPOSE:To obtain a processing device of exhaust gas which is economical and superior in handiness and can be applied to home use also, by a method wherein a soot removing part and a washing part having a pump are formed, a water tank having a heater on the lower part of the soot removing part is pushed up and a suction port of the soot removing part is closed. CONSTITUTION:When a water tank 17 provided on the lower part of a soot removing part 6 is pushed upward (a locking mechanism is not illustrated herein), a microswitch (not illustrated) is worked, a fan 25 is suspended irrespective of selection of a control button 27 of an air quantity and a heater 26 is electrified simultaneously with a turning of a pump 13. A suction port 16 is closed through an upward movement of the water tank 17. As a water level of the water tank 17 becomes above the suction port 14 of the pump 13, water (hot water) containing detergent is sucked up through an elastic pipe 15 without sucking in air from the suction port 14.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a smoke evacuation device having a collision-type oil smoke removal function and a oil smoke removal section cleaning function.

Conventional structure and problems Conventionally, this type of collision-type smoke evacuation device bends the direction of the sucked air with a buckle plate, causing the oil and fat in the air to collide with the inner wall of the smoke evacuation device body using inertial force. Attach it and remove it.
The remaining oil and fat inside the main body was removed by spraying hot water containing detergent from a spray nozzle installed inside.

This is mainly limited to commercial kitchen equipment and has not spread to general households. The reason for this is that, as shown in Figure 1, the system for the smoke evacuation system is similar to the one shown in Figure 1. In order to pressurize hot water with pump 1 to clean the oil smoke removal section and then drain it, a large amount of hot water and detergent are required. It is conceivable that equipment such as a pump for pressurizing the hot water, a hot water supply equipment 2 for supplying a large amount of hot water, etc. will be large. In addition, although this is not a big problem for commercial use, there is the problem of steam during cleaning, which may become a problem when used for home use. In other words, since hot water is used to clean the oil smoke removal section, steam may flow back into the room from the suction port 3 and cause dew condensation. Therefore, the conventional smoke evacuation device cannot be used as is for home use.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a smoke evacuation device that is compact, economical, and easy to use, and can be used for household purposes as well.

The smoke evacuation device of the present invention includes a smoke removal section and a cleaning section having a pot in the main body of the smoke evacuation device, which is provided at a certain distance above the oven, and a heater below the oil smoke removal section. By pushing up the water tank with the oil smoke removal unit and closing the intake port of the oil smoke removal section, cleaning can be started. At the same time, the water level of the water tank is raised higher than the pump intake port. This reduces the amount of detergent and water consumed when cleaning the oil smoke removal section, prevents steam and water droplets from flowing back into the room, and makes the smoke exhaust system more compact.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 4, 4 is a smoke evacuation device main body provided at a certain distance from the range 6, and is composed of a smoke removal section 6 and its cleaning section. 30 for range 5
There is a heating section 8 consisting of a stove or the like and its operation section 9, and an oven 10ρ is installed below the range 6. On the other hand, the front surface of the oil smoke removal section 6 of the smoke evacuation device main body 4 above the range 6 is a smoke guide plate 11 which also serves as a shelf, on which a microwave oven 12 or the like is placed, for example. A pump 13 for circulating cleaning water is provided inside the cleaning section 7, and its suction port 14 is connected to a water storage tank 17 provided below the suction port 16 of the oil smoke removal section 6 through a telescopic pipe 15. There is.

The water tank 17 can be moved up and down, and when lowered, the intake port 16
is opened, and when rising, the intake port 16 is closed and the water level is positioned higher than the intake port 14 of the pump 13. A pipe 21 connects a discharge port 18 of the pump 13 to a nozzle 19, 20 in the oil smoke removal section 6. A plurality of huffles 22, 23 are provided in the passage 6a of the oil smoke removal section 6.
．． 24, and a fan 26 is provided at the upper end to discharge the air that has passed through the baffle plates 22 to 24 to the outside.

26 is a heater provided in the water tank 17, 27 is an air volume control button for the fan 25, and 28 is a drain cock for the water tank 17.

The operation in the above configuration will be explained. First, the case of exhausting smoke will be explained based on FIG. The fan 26 (which may be configured to rotate at an optimum air volume) rotates, and the air containing oil smoke enters the oil smoke removal section 6 of the smoke evacuation device main body 4 from the intake port 16 along the smoke guide plate 11.

The air that has entered the oil smoke removal section 6 passes through the baffle plate 24°26
．． The oil smoke particles rise while being bent in direction at 26, but among the oil smoke particles, particles with a size of several 10/l to several 100 microns collide and adhere to the inner wall surface of the smoke evacuation device 4 due to inertial force when being bent. The air from which most of the oil and fat content has been removed is discharged from the fan 25 to the outside.

Next, the case of cleaning the oil smoke removal section 6 will be explained based on FIG. 4. When the water tank 17 provided below the oil smoke removal section 6 is pushed up to one side (the locking mechanism is not shown), a microswitch (not shown) is activated, regardless of the selection of the air volume control button 27. At the same time as the fan 25 stops and the pop 13 rotates, the heater 26 is energized.

In addition, the intake port 16 is closed by the upward movement of the water tank 17.

At this time, the water level in the water tank 17 is higher than the suction port 14 of the pump 13, so water (hot water) containing detergent passes through the expandable pipe 16 without sucking air through the suction port 14.
is absorbed. The water pressurized by the pump 13 passes through the pipe 21 from the discharge port 18 to the nozzles 19 and 2.
Inner wall and baffle plate 2 inside oil smoke removal method 6
4, 26.

The oil and fat deposited on 26 is cleaned. The cleaning water then washes along the inner wall of the smoke removal section 6 and returns to the water tank 17. During this time, the water is heated by the heater 26 and turns into hot water, which powerfully cleans oil and fat. After cleaning for a certain period of time, the pump 13 and heater 26 are automatically de-energized.

Water containing detergent after being used for several months may be drained from the drain 38 and fresh water containing detergent may be supplied from the intake port 16.

Effects of the Invention As shown in the above embodiments, the smoke evacuation device of the present invention has the following effects.

(1) Since water (hot water) containing detergent is circulated and used repeatedly, there is less wastage of detergent and water, and a large hot water supply facility is not required, making the smoke exhaust system more compact.

(2) Since the intake port is opened while the oil smoke removal section is being cleaned, steam and water droplets do not flow back into the room and form dew condensation.

(3) By pushing the water tank upward, the water level in the water tank is higher than the pump's suction port, and the water is sucked up without sucking in air, eliminating the need for a large self-sufficient tank like a self-contained pump, and cleaning the water tank. As a result, the smoke evacuation system as a whole becomes more compact.
