An air purifier 100 according to an embodiment of the present invention includes a housing; a smoke passage 150 installed in the housing, one side communicates with the hood 110 and the other side communicates with the external exposed outlet 120, and is formed by bending multiple layers;

an injection nozzle 140 installed on the upper bending portion 151 of the smoke passage 150 to spray a liquid into the smoke passing through the smoke passage 150; and

Liquid receiving provided so as to communicate with the lower bending part 152 of the smoke passage 150 , and to receive the liquid sprayed from the injection nozzle 140 to maintain a constant water surface in the lower bending part 152 . The unit 160; may be configured to include.

For example, the duct system is installed in the kitchen or hall of a restaurant and the hood 110 for absorbing smoke is connected to the outlet 120 through the duct, and smoke generated when grilling meat, etc. in the kitchen or hall of the restaurant is discharged through the outlet ( 120), in this case, the air purifier 100 according to an embodiment of the present invention may be installed between the hood 110 and the outlet 120 in the duct system. Specifically, one side of the smoke passage 150 of the air purifier 100 according to the present embodiment may communicate with the hood 110 , and the other side may be connected to the duct system in communication with the outlet 120 .

In a general duct system, the smoke generated during the process of grilling meat, etc. is discharged to the outside through the duct system. In this case, the smoke containing harmful substances such as fine dust and oil is discharged to the outside as it is, which is the main culprit of air pollution By inserting and installing the air purifier 100 according to the embodiment in the duct system, it is possible to separate harmful substances from smoke and to discharge clean air to the outside through the outlet 120 .

According to an embodiment, the smoke passage 150 may be formed in a form that is bent in multiple layers. According to an embodiment, the smoke passage 150 is formed to extend upward and then bend downward to form the upper bending part 151 , and then extend downward again and then bend upward to form the lower bending part 152 . can form. That is, here, the upper bending part 151 means a portion in which the smoke passage 150 is bent from the upper side, and the lower bending portion 152 may mean a portion in which the smoke passage 150 is bent from the lower side. .

This structure generates a vortex in the flow of smoke when smoke passes through the inside of the smoke passage 150 , thereby slowing the passing speed of the smoke so that the smoke sufficiently stays inside the smoke passage 140 . Therefore, the liquid sprayed from the spray nozzle 140 can be sprayed into the smoke more uniformly and sufficiently, and the amount of collecting harmful substances such as fine dust and oil in the smoke is increased.

Since the smoke passage 150 is formed by continuously bending several layers in the upper and lower directions, the passage portion and the lower bending portion extending downwardly from the upper bending portion 151 to the lower bending portion 152 . When smoke passes from 152 to the upper bending part 151, that is, in the passage portion extending upward, the liquid sprayed from the spray nozzle 140 is sprayed downward to pass through a large amount of smoke. It can efficiently collect harmful substances such as fine dust and oil in the smoke.

This structure is possible because the injection nozzle 140 is located on the upper bending part 151 and the liquid receiving part 160 for accommodating the liquid sprayed from the injection nozzle 140 is located on the lower bending part 152 . to be.

According to an embodiment, the lower portion including the bottom surface of the housing may function as the liquid accommodating part 160 . The smoke passage 150 may be installed inside the housing, and the lower bending part 152 of the smoke passage 150 is disposed adjacent to or in contact with the bottom surface of the housing, and the lower bending part 152 is Since the lower part of the housing is in communication with the lower part of the housing, a part or all of the lower part of the bending part 152 of the smoke passage 150 is sprayed and the liquid collecting harmful substances can be accommodated while maintaining a constant water surface. have.

One side of the lower bending part 152 of the smoke passage 150 has a structure that can communicate with the bottom surface of the housing. According to an embodiment, the lower bending portion 152 and the bottom surface of the housing may communicate with each other by a structure in which a through hole is formed in the lowest portion 153 of the lower bending portion 152 of the smoke passage 150 . .

The lower bending part 152 may have a shape that is narrowed in the downward direction. Here, the through hole may be formed in the lowermost portion 153 having a shape that is narrowed in the downward direction according to an embodiment. According to an embodiment, the lower bending part 152 may have a round shape or an inclined shape. In this case, the through hole may be formed in the lowest portion 153 of a round shape or an inclined shape. In the embodiment of FIG. 1 , the lower bending part 152 has an inclined shape. The structure in which the lower bending part 152 has a shape that is narrowed in the downward direction allows the liquid sprayed from the injection nozzle 140 to be smoothly collected to efficiently maintain a constant water surface.

Here, the degree to which the liquid maintains a constant water level from the bottom of the lower bending part 152 means that the lower bending part 152 maintains a water level to the extent that the portion communicating with the lower part of the housing is submerged with the liquid. can do.

Smoke drawn in from the hood 110 rides the smoke passage 150 and moves toward the outlet 120. In this case, if the liquid does not maintain a constant water surface, the lower bending portion 152 of the smoke passage 150 and the lower housing Since the pressure leaks out to the part where the side is in communication, the pressure cannot be maintained inside the smoke passage 150 , so the smoke cannot move. Therefore, the portion where the lower bending portion 152 of the smoke passage 150 and the lower housing communicate with each other should be located under a certain water surface and blocked with liquid. When the liquid maintains a constant water surface, since the communicating portion is surrounded by the liquid and blocked, the pressure in the smoke passage 150 is maintained so that the smoke can move to the discharge port 120 .

Here, the water surface may be controlled to be maintained in a state raised to a certain height from the bottom of the lower bending part 152 . According to an embodiment, the control of the water surface may be performed by a flow control valve installed in the discharge pipe 170 . This will be described later.

According to an embodiment, a filter unit 130 connected to an upstream side of the discharge port 120 communicating with the other side of the smoke passage 150 to filter the smoke may be included.

The filter unit 130 may include a plurality of filters, and may perform a function of removing moisture from smoke. By liquid jetting, the smoke contains moisture. Therefore, the dry air can be discharged by filtering moisture before being discharged to the outside through the discharge port 120 .

According to an embodiment, the heater 200 may be installed on the lower side of the housing. The heater 200 may be installed on the bottom surface of the housing, depending on the embodiment. The heater 200 may include a heating wire embedded in the bottom surface according to an embodiment.

The heater 200 may serve to heat the liquid contained in the lower portion of the housing, that is, the liquid accommodating part 160 to raise it to a constant temperature. The sprayed liquid collects oil from the smoke and falls in the downward direction and is accommodated in the liquid accommodating part 160. In this case, pork oil may be solidified at room temperature. Therefore, it is heated through the heater 200 so that the pork oil is maintained in a liquid state so that it can be discharged through a pipeline.

According to an embodiment, the air purifier 100 according to the present invention receives the liquid discharged from the liquid accommodating part 160, separates harmful substances from the received liquid, and circulates the liquid from which the harmful substances are separated. In order to be provided to supply to the injection nozzle 140 again, one side is connected to the liquid accommodating part 160, the other side is connected to the injection nozzle 140 and a cooling line for separating the harmful substances therein ( 190) may be configured to include an installed discharge tank.

According to an embodiment, the cooling line 190 may be installed on the bottom surface of the discharge tank, and may be installed on the discharge pipe 170 connecting the liquid accommodating part 160 and the discharge tank. The cooling line 190 may be connected to the cooler 290 to circulate the cooling liquid and cool the liquid. The cooling line 190 is heated in the liquid accommodating part 160 and the liquid maintained in a liquid state is discharged and introduced into the discharge tank to lower the temperature of the liquid to solidify the pork oil and the like collected in the liquid. The reason for solidifying pork oil and the like is to separate it from the liquid. The solidified pork fat separated from the liquid sinks to the bottom, and it is easy for the operator to take it out of the discharge tank and collect it later.

According to an embodiment, the first flow control valve 270 may be installed in the discharge pipe 170 , and the second flow control valve 280 may be installed in the supply pipe 180 . The first flow control valve 270 and the second flow control valve may refer to solenoid valves that are electrically controlled and operated according to an embodiment.

A filtration device for filtering and separating fine dust, oil, etc. may be installed in the discharge tank. Here, filtration does not mean only a physical filter, but may mean removing fine dust by a chemical reaction.

Such a structure may constitute a recirculation system for recirculating the liquid. The operation method of this recirculation system will be described in detail.

When the operator opens both the first flow control valve 270 and the second flow control valve 280 , the liquid may be supplied to the injection nozzle 140 by the circulation pump 250 riding the supply pipe 180 .

The supplied liquid is sprayed from the injection nozzle 140 and comes into contact with the smoke moving through the smoke passage 150 . The liquid in contact with the smoke collects fine dust, oil, etc. contained in the smoke and falls to the liquid receiving unit 160 .

A heater 200 is installed in the liquid accommodating part 160 to heat the liquid that collects and accommodates the fallen fine dust, oil, etc. to keep the pork oil and the like in a liquid state.

The liquid that collects and accommodates fine dust, oil, etc. through the discharge pipe 170 connected to the liquid receiving unit 160 moves to the discharge tank. The liquid moving through the cooling line 190 disposed on the discharge tank or discharge pipe 170 is cooled, and oil is solidified and separated in the liquid. The separated and solidified harmful substances are accumulated on the bottom surface of the discharge tank.

On the other hand, the liquid may be filtered of harmful substances such as fine dust by a filter, etc., and the liquid purified by separating fine dust and oil is pressurized through the circulation pump 250 and rides the supply pipe 180 again through the injection nozzle 140 ) is resupplied.

When the operator closes both the first flow control valve 270 and the second flow control valve 280, the circulation of the liquid is stopped. At this time, the operator can collect and clean the solid material wrapped in the bottom surface of the discharge tank.

On the other hand, the operator controls the amount of the injected liquid and the discharged liquid by opening or closing the first flow control valve 270 and the second flow control valve 280 in an appropriate amount to be accommodated in the liquid accommodating unit 160 . It is possible to control the level of water level of the liquid constant.

According to the embodiment, the first flow path control valve 270 and the second flow path control valve 280 may be automatically controlled. The first flow control valve 270 and the second flow control valve 280 may be opened or closed according to a predetermined time interval. Also, the first flow control valve 270 and the second flow control valve 280 may be opened or closed according to the turbidity of the liquid receiving part.

For example, the first flow control valve 270 may be opened when the liquid accommodating part is accommodating the liquid for a certain period of time or when the turbidity deviates from the reference value, and the first flow control valve 270 is opened to accommodate the liquid. The liquid contained in the unit can be moved to the discharge tank through the discharge pipe.

Turbidity can be sensed by measuring the load value of the strainer installed in the pipeline, or a part of the pipeline is made transparent, and the operator visually observes the transparent part of the pipeline and the liquid visible in the pipeline is turbid over a certain level. By opening the flow path control valve 270, the liquid contained in the liquid accommodating part may be discharged.

Described as a configuration included in ). Here, the connection part 300 may also be a pipeline according to an embodiment. The coil heater 320 may be coiled along the circumferential surface of the pipeline, which is the receiving pipe portion 310 .

Here, the accommodating pipe part has a configuration corresponding to the lower part including the bottom surface of the housing functioning as the liquid accommodating part 160 in the first embodiment described above, and the flow path is blocked by the flow path control valve to accommodate the liquid. In this respect, the function is substantially the same as that of the liquid accommodating part 160 in the first embodiment.

In addition, in this embodiment, the coil heater 320 may correspond to the heater 200 installed on the lower side of the housing, that is, on the bottom surface in the above-described embodiment (meaning the first embodiment). In this embodiment, the coil heater 320 may be wrapped around the circumferential surface of the receiving pipe, not the heating wire embedded in the bottom surface of the housing.

The structure in which the coil heater surrounds the circumferential surface of the receiving pipe effectively heats the receiving pipe to effectively prevent solidification of substances such as pork oil.

In the present embodiment, the lower bending portion 152 may have a shape that is narrowed in the downward direction. Here, the connection part 300 may be connected to the lowermost part 153 having a shape that is narrowed in the downward direction according to an embodiment.
