Description

  The present invention relates to a purification device that generates ozone and purifies a room and a grease trap using the ozone.

  Drainage discharged from restaurants and kitchens contains a large amount of oil, and cannot be drained as it is from the viewpoint of preventing water pollution. In view of this, an oil separator called a grease wrap is installed in the kitchen and its surroundings, the oil is removed by putting the waste water into the grease wrap at once, and the waste water is drained to the sewer in that state.

  In this grease trap, the drainage and the oil separated from the drainage exist, and the presence of the drainage and the oil makes it easy for insects such as microorganisms and flies to breed. And, when these microorganisms and insects are propagated, it has an adverse effect on hygiene and gives off a bad odor from this grease trap.

Therefore, in order to solve such a problem, a purification device that generates ozone, sends air containing the ozone into the grease trap, sterilizes and kills the microorganisms and insects, and purifies the grease strap. Have been developed (for example, Patent Document 1).

  In the purification device, the range of the purification effect is mainly in the grease trap, and the purification effect hardly reaches other parts. Moreover, when the air containing ozone is sent into the grease trap, a part of the waste water in the grease strap is scattered into the atmosphere by the air, and the microorganisms and the like are also brought into the atmosphere as a result. There is a risk of scattering. Therefore, particularly when a grease trap is installed on the floor of a room such as a kitchen, the purification effect on the entire range including the grease strap and the room is not perfect, and this purification effect was further improved. There was a need for a purification device.

  Therefore, the present invention provides a purification device that further improves the purification effect on the entire range including the oil separator represented by the grease trap and the room, and further improves the purification effect with only one ozone generation unit.

An ozone generation amount control unit that controls the amount to be generated, and the heater control unit heats the heater when the ozone generation amount control unit is controlled not to generate the ozone. It is configured to remove moisture in the dehumidifying unit.

  According to the first aspect of the present invention, the purification device includes not only the first discharge portion that discharges ozone to the oil separator, but also the second discharge portion that discharges ozone into the atmosphere. , Ozone can be released not only into the oil separator but also into the atmosphere. Therefore, even when the microorganisms or the like are scattered in the atmosphere when performing the purification operation in the oil separator, these microorganisms can be sterilized and purified.

  Furthermore, since the ratio of the amount of ozone discharged from the first discharge section and the second discharge section can be controlled by the discharge amount control section, the discharge amount control section can control the oil separator and the atmosphere. By appropriately adjusting the amount of ozone released therein, the oil separator and the atmosphere can be more effectively purified.

  According to the invention of claim 2, since the discharge amount control unit is configured to switch the ozone to be released to the outside air after releasing the ozone to the oil separator.

Therefore, even when the microorganisms or the like are scattered in the atmosphere when performing the purification operation in the oil separator, these microorganisms can be sterilized and purified.

  According to the invention concerning Claim 3, since the ventilation part which assists discharge | release of the said ozone is provided in the said purification apparatus, discharge | release of ozone to the said oil separator and the said outside air more reliably is performed. I can do it. Furthermore, since the flow for diffusing the ozone in the oil separator and in the outside air can be created by the blowing section, a more effective purification effect can be obtained.

  According to the invention of claim 4, the generation of ozone is performed by being discharged by a discharge unit provided in the ozone generation unit, and the air in which this discharge is performed is dehumidified in advance by the dehumidifier.

The air containing ozone is discharged into the grease trap 20 through the first discharge pipe 31, the blower 40, and the second discharge pipe 32.

  Next, the wiring situation of this purification apparatus 1 will be described with reference to FIG.

  The power source Vs is an AC power source, and a circuit in which a power switch 111, a first switch SW1, a second switch SW2, and a discharge unit 128 are connected in series is connected between terminals of the power source Vs.

  A circuit in which the fourth switch SW4 and the heater 127 are connected in series, a circuit in which the pump 122 is disposed, and a circuit in which the blower 126 is disposed are connected in parallel with the second switch SW2 and the discharge unit 128. Yes.

In addition, a circuit in which the third switch SW3 and the electromagnetic valve 125 are connected in series is connected in parallel with the discharge unit 128, and the blower 40 is connected in parallel with the electromagnetic valve 125.

  Next, operation | movement of this purification apparatus 1 is demonstrated using FIG.

  First, the power switch 111 is turned on, and three times T1, T2, and T3 are set by the timer 112 or the like. At this time, the first to third switches SW1, SW2, and SW3 are on, and the fourth switch SW4 is off.

  In such a state, the discharge unit 128, the counter 113, the pump 122, and the blower 126 are operated, and the electromagnetic valve 125 and the blower 40 are also operated. That is, air is supplied to the inside of the apparatus main body 10 from the intake port 116 via the pump 122, ozone is generated by the discharge unit 128 in the ozonizer 124 using this air, and the air containing ozone is supplied to the solenoid valve 125. The exhaust gas is discharged to the grease strap 20 through the side exhaust port 115, the blower 40, and the second discharge pipe 32.

  When the time T1 elapses after the above operation is performed, the third switch SW3 is turned off by a control signal from the control unit 50, and the operations of the electromagnetic valve 125 and the blower 40 are stopped accordingly. That is, the air containing ozone is released from the front exhaust port 114 into the indoor atmosphere via the electromagnetic valve 125 and the blower 126.

  Further, when the time T2 has elapsed from the start of the operation, the second switch SW2 is turned off and the fourth switch SW4 is turned on by the control signal from the control unit 50, and the operations of the discharge unit 128 and the counter 113 are stopped. The heater 127 is heated. That is, moisture contained in the moisture absorbent in the dehumidifying unit 123 is evaporated by the heater 127, and this evaporated moisture is supplied to the inside of the apparatus main body 10 via the pump 122 by the ozonizer 124, the electromagnetic valve 125, It is discharged from the front exhaust port 114 through the blower 126. By performing this operation, the moisture of the hygroscopic material in the dehumidifying part 123 is removed, and the hygroscopic capacity of the hygroscopic material is recovered. Furthermore, in such a case, ozone is not generated in the ozonizer 124, and ozone contained in the air sucked from the intake port 116 is decomposed by the activated carbon filter 121, so that ozone contained in the room is decomposed. Will be promoted.

  Further, when the time T3 has elapsed from the start of the operation, the first switch SW1 and the fourth switch SW4 are turned off by the control signal from the control unit 50, the operations of the pump 122 and the blower 126 are stopped, and the heater 127 is heated. Also stop.

  According to the above configuration, the ozone-containing air can release ozone not only to the grease trap 20 but also to the indoor atmosphere. Further, since the controller 50 and the electromagnetic valve 125 are configured to switch the air containing ozone to the grease trap 20 so as to release the air into the indoor atmosphere, After purifying the room, the room can be purified. Therefore, even when microorganisms or the like are scattered in the indoor air when performing the purification work in the grease strap 20, these microorganisms can be sterilized and purified, and a purification effect can be obtained more reliably. It becomes.

  Further, since the blower 126 for assisting the discharge of the air containing ozone from the front exhaust port 114 and the blower 40 for assisting the discharge of the air to the grease trap 20 are provided, the grease trap 20 and the indoor space are provided. Ozone can be released more reliably into the atmosphere. Furthermore, the presence of the blower 126 can create a flow for diffusing the ozone into the indoor atmosphere, and the presence of the blower 40 creates a flow for diffusing ozone in the grease trap 20. This makes it possible to obtain a more effective purification effect.

  In addition, since the air introduced into the ozonizer 124 has been previously dehumidified by the dehumidifying unit 123, when the discharge unit 128 is operated to generate ozone, the moisture contained in the air causes the air to be introduced. It is possible to prevent the discharge unit 128 from being damaged. Therefore, the durability of the purification device 1 can be improved.

  In addition, although the dehumidifying function of the moisture absorbent in the dehumidifying unit 123 decreases as moisture in the air is absorbed, according to the configuration of the present embodiment, the moisture of the moisture absorbent is heated by heating the heater 127. Therefore, it is possible to prevent the dehumidifying function in the dehumidifying unit 123 from being lowered.

  Further, since the heater 127 is heated when ozone is not generated in the ozonizer 124, dehumidification in the dehumidifying unit 123 can be performed using a time during which ozone is not generated, and the dehumidifying unit 123 is more efficiently dehumidified. Can be done.
