A float 5 for controlling the amount of cleaning liquid stored and a heater 6 for raising the temperature of the cleaning liquid were attached to the bottom of the cleaning liquid storage container 4. The suction port 8 of the pump 7 is connected to the cleaning liquid storage container 4 via a filter 9 with a hose 10, and the cleaning liquid discharged from the discharge port 11 of the pump 7 is directed to the bottom wall 1 of the smoke evacuation device main body 1.
Each cleaning nozzle 14 is
The cleaning fluid is sent to the main body 1 of the smoke evacuation device, is ejected, and returns to the cleaning fluid storage container 4 again, following a circulation route.

However, in the above structure, since the cleaning liquid storage container 4 is integrated with the smoke evacuation device main body 1, the workability of mounting the float 5 and the heater 6 into the cleaning liquid storage container 4 is very poor. Furthermore, the oil and dust that adheres to the wall surface when the oil smoke passes through the wind cylinder 3 is washed away with cleaning liquid, and the cleaning liquid that has been used several times is replaced with a new one, but oil and dust adhere to the float etc. This is difficult to avoid, causing frequent malfunctions of the float, and at the same time, repair work is difficult to perform, and maintenance and inspection such as replacement of the filter 9 also poses operational problems.

Purpose of the Invention The present invention solves these conventional problems, improves workability during assembly, simplifies maintenance and inspection such as replacing filters, and improves the reliability of the operation of floats, etc. It provides a smoke device.

Structure of the Invention The smoke evacuation device of the present invention includes a main body of the smoke evacuation device in which a wind cylinder is formed, a plurality of cleaning nozzles disposed inside the main body of the smoke evacuation device and ejecting a cleaning liquid, and a plurality of cleaning nozzles that spray the cleaning liquid into each cleaning nozzle. and a cleaning liquid storage container for storing cleaning liquid, the cleaning liquid storage part being removably attached to the lower part of the smoke evacuation device main body, and a heater attached to the cleaning liquid storage container; The float, filter, etc. can be combined into a unit as a cleaning liquid reservoir, which improves workability, eases maintenance, and improves reliability.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 3, 20 is the main body of the smoke evacuation device, which has a wind cylinder 22 formed therein through which oil smoke sucked in from the oil smoke intake port 21 passes, and 23 is a smoke evacuation device body disposed inside the wind cylinder 22 through a piping route 24, through which cleaning liquid is passed. The jetting cleaning nozzle 25 has a guide rod 26, and this guide rod 2
A float 27 that moves up and down along line 6 to detect when the cleaning liquid is full and empty, and a heater 2 that raises the temperature of the cleaning liquid.
8 is attached to the cleaning liquid storage container for storing cleaning liquid, and is detachable from the cleaning liquid reservoir part 33. A pump 29 is fixed to a cleaning liquid reservoir 33 and is removably connected to the cleaning liquid storage container 25 through a suction port 30, and has a water outlet 31 removably connected to an end portion 32 of the piping route 24 via a seal. , 33 are the pump 29 and the cleaning liquid storage container 25.
A cleaning liquid reservoir is provided with chuck portions 35 on the upper left and right side walls that are elastic and engage with protrusions 34 at the bottom of the smoke evacuation device main body 20, and are removably attached to the bottom of the smoke evacuation device main body 20. Department. In addition, if you press the lower part of the chuck part 35, the cleaning liquid reservoir part 3 will be released.
3 can be easily removed from the main body 20 of the smoke evacuation device. 36 is a filter fitted into the communication port 38 in the bottom plate portion 37 of the smoke evacuation device main body 20, and 39 is a plurality of buttfuls arranged in a staggered manner in the wind body 22 to forcibly bend the flow of oil smoke passing through it. be.
Note that the communication port 38 communicates the inside of the smoke evacuation device main body 20 and the cleaning liquid storage container 25.

Next, in the above configuration, when the blower (not shown) on the upper part of the smoke evacuation device main body 20 is operated, oily smoke is sucked in from the intake port 21, and when it passes through the wind barrel 22, the flow is forced by the baffle 39. The oil particles collide and adhere to the inner wall surface of the wind cylinder due to their inertia, and the oil smoke from which most of the oil and fat has been separated and removed is exhausted. This attached oil and fat is removed by pump 29, which pumps the cleaning liquid in cleaning liquid storage container 25 heated by heater 28.
It is washed away by being ejected from the cleaning nozzle 23 onto the inner wall surface of the wind cylinder. The cleaning liquid that has cleaned the inner wall surface of the wind cylinder returns to the cleaning liquid storage container 25 from the communication port 38 through the filter 36, and is again sent to the cleaning nozzle 23 by the pump 29 for circulation. In this way, the cleaning liquid used for several cleanings is drained through a drain valve (not shown), and new cleaning liquid is supplied. The above-mentioned cleaning process is automatically carried out in a certain cycle, but when supplying and discharging the cleaning liquid in the cleaning liquid storage container 25, the amount of cleaning liquid is detected by the float 27, and the end point of water supply and drainage can be determined. .

In addition, in the above structure, the cleaning liquid reservoir 33 can be assembled as a unit separately from the assembly of the smoke evacuation device main body 20, making it easy to install the float, heater, etc., and the work efficiency during assembly is further improved. At the same time, since the cleaning liquid reservoir 33 is easy to attach and detach, maintenance and inspection including filter replacement, float cleaning, pump and other repairs are easy. Since the cleaning liquid flowing from the communication port 38 passes through the filter 36, dust and the like do not adhere to the float, thereby improving reliability.

FIG. 4 shows still another embodiment, in which a swirl chamber 40 of a pump 29 is placed in a cleaning liquid storage container 25 and attached via a side wall 41, and a piping path 24 that can be attached and detached to a water outlet 31 of the swirl chamber 40 is shown in FIG. The filter 3 is stretched over the communication port 38 provided in the bottom plate portion 37.
It passes through 6. In addition to the effects of the previous embodiment, this embodiment eliminates the need for a seal 42 at the portion where the end portion 32 of the piping route 24 penetrates the bottom plate portion 37 of the smoke evacuation device main body 20, which is advantageous in terms of cost. This has the effect of improving reliability.

In each of the above embodiments, the end point of water supply and drainage of the cleaning liquid was detected using a float, but a means such as a pressure switch may also be used, and the device means of the cleaning liquid reservoir may also be fixed with screws or the like. The effect remains the same. In short, it is sufficient that the cleaning liquid reservoir is separated from the main body of the smoke evacuation device and that the cleaning liquid reservoir is supported in a detachable manner.

Effects of the Invention As is clear from the above embodiments, the smoke evacuation device of the present invention separates the cleaning liquid reservoir from the main body of the smoke evacuation device, and integrates components such as the cleaning liquid storage container and the pump with the cleaning liquid reservoir. By supporting the main body in a detachable manner, workability during assembly is improved, and filter replacement and maintenance and inspection of the float, pump, etc. can be easily performed.
