  The present invention relates to an air treatment device that removes odors generated by the use of an electric heater that does not involve combustion.

  There are electromagnetic cookers such as IH cooking heaters and electric heaters such as halogen heaters (hereinafter referred to as “electric heaters”) as heating cookers, and these electric heaters are harmful to the human body during cooking because they do not involve combustion during heating. It has the feature that no carbon dioxide is generated. For example, in a heating cooker with combustion, carbon dioxide generated during cooking needs to be discharged from the house, so it was discharged out of the house by a ventilator, etc. It is only a pollutant component such as oil smoke, moisture, cooking odor, etc. If the pollutant component is treated from the air containing this pollutant component (hereinafter referred to as polluted air), there is no need to exhaust outside the house.

  Therefore, as a conventional technique for treating contaminated air generated when cooking using an electric heating appliance, the odor resulting from cooking is adsorbed by a deodorizing device composed of activated carbon and the deodorized air is indoors. A cooking odor treatment apparatus for exhausting air has been proposed. In addition, when the cooking odor treatment device is not in operation, the activated odor is applied to the activated carbon to re-release the adsorbed odor, and the re-released odor is exhausted to the outside so that the deodorizing ability of the activated carbon can be maintained. It is also proposed to extend In addition, a function that promptly replaces or cleans activated carbon when a decrease in deodorizing performance is detected by an odor sensor has been proposed (see, for example, Patent Document 1).

  However, in the prior art of Patent Document 1, the period in which sufficient deodorizing ability can be maintained by re-releasing the odor adsorbed on the activated carbon to the outside is extended, but in the end, maintenance such as replacement or cleaning of the activated carbon is required. There was a problem that it was necessary. In addition, an exhaust passage for discharging the odor re-released from the activated carbon to the outside is required, and there is a problem that the installation layout of the processing apparatus is limited and the structure becomes large.

  The present invention has been made to solve the above-described problems, and provides an air treatment device capable of maintaining stable deodorization performance for a long period of time without configuring an exhaust air passage communicating with the air treatment device and the outside. It is for the purpose.

And a deodorizing means for removing at least odor from the contaminated air sucked from the suction port, a control means for controlling the operation of the blower and the heater, and the deodorizing means includes at least a deodorizing agent that adsorbs odor and oxidatively decomposes, and deodorizing The control means is configured to include a heater that heats and activates the agent, and after receiving a signal to stop the operation, the control unit operates by shifting to a low speed operation in which the number of rotations is reduced before the signal is received.

  By configuring the air treatment device according to the present invention as described above, it is possible to suppress a decrease in the deodorization performance without restricting the layout of the air treatment device, and without performing maintenance on the deodorization means. In addition, the effect of maintaining stable performance for a long time can be obtained.

[Embodiment 1]
FIG. 1 is a front view of a cabinet incorporating an air treatment device according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of the cabinet incorporating the air treatment device.
The air treatment apparatus 100 according to the first embodiment is installed in a cabinet 101 as an air treatment apparatus for a kitchen, and particularly heats the heating container 102 without burning, typified by an IH cooking heater. Then, it is a device for processing the contaminated air 104 containing oily smoke, water vapor, odor and the like, which is generated when cooking with the electric heater 103 for cooking. In the cabinet 101, an electric heating device 103 is installed on the upper side on the front side, and an air treatment device 100 is installed on the back side of the electric heating device 103.

The air treatment apparatus 100 includes a suction hood 2 having a suction port 1 that opens to the electric heater 103 side, a blower 3 that generates a suction flow that sucks contaminated air 103 from the suction port 1, and a suctioned contaminated air 104. A deodorizing device 4 (deodorizing means) that adsorbs and purifies at least odor and a blowout port 5 that discharges the purified air 105 to the periphery of the cabinet 101 outside the air processing device 100 are provided. Further, the blower 3 and the deodorizing device 4 of the air treatment device 100 are provided in the cabinet 101 so that the cabinet 101 can be used widely. In addition, a filter 6 (oil smoke / water vapor removing means) made of stainless steel, aluminum or the like that removes oil smoke / water vapor is installed in the vicinity of the intake port 1 of the intake hood 2 in a detachable manner. It is configured to be easily removed and removed by removing the cover 7 of the mouth 1. The inside of the air treatment device 100 is communicated with an intake side air passage 8 that communicates the suction port 1 and the blower 3 and an exhaust side air passage 9 that communicates the blower 3 and the blowout port 5.
The air treatment device 100 receives an operation start instruction by pressing a power switch among the plurality of switches 10 provided in the suction hood 2, and starts the operation of the blower 3. The polluted air 104 is sucked from the suction port 1 by the suction flow generated by the operation of the blower 3, and the sucked polluted air 104 is first removed most of the oil smoke and water vapor by the filter 6, and then the odor by the deodorizer 4. And the smoke and water vapor not captured by the filter 6 are also adsorbed and purified. The purified air 105 passes through the blower 3 and is exhausted from the air outlet 5 to the outside of the air processing apparatus 100. Further, the suction hood 2 is installed to be inclined toward the electric heater 103 so that the contaminated air 104 can be easily sucked. Moreover, although the air blower 3 and the deodorizing apparatus 4 of the air treatment apparatus 100 are provided in the cabinet 101 so that the cabinet 101 can be used widely, it is not restricted to this.

Next, the deodorizing apparatus 4 used in the air treatment apparatus 100 according to Embodiment 1 will be described with reference to FIGS. FIG. 3 is a front view of the deodorizing apparatus according to Embodiment 1 of the present invention, and FIG. 4 is a side view of the deodorizing apparatus.
The deodorizer 4 includes an aluminum fin 11 (metal plate) carrying a deodorizer, a rod-shaped PTC heater element 12 (heater) for heating the aluminum fin 11, and a power supply terminal 13 provided on the end face of the PTC heater element 12. A plurality of PTC heater elements 12 are arranged side by side so as to straddle the intake side air passage 8, and are fixed in contact with the aluminum fins 11 arranged in parallel to the intake side air passage 8. .

The deodorizer carried on the aluminum fin 11 uses a catalyst composed mainly of manganese oxide and a mixture of one or more of noble metals such as platinum, palladium, ruthenium and rhodium or other metal oxides. . In addition, as other metal oxides, metal oxide catalysts such as copper oxide, titanium oxide, chromium oxide, iron oxide, nickel oxide, zinc oxide, and cobalt oxide are used.
The catalyst as described above has a property of adsorbing an odor and oxidatively decomposing the adsorbed odor using ambient oxygen. Heating the catalyst activates the catalyst and has the property of improving the deodorizing performance of the catalyst.
Therefore, the deodorizing device 4 generates heat from the PTC heater element 12 by supplying power from the power supply terminal 13, conducts the heat to the aluminum fins 11, and heats and activates the catalyst carried on the aluminum fins 11, resulting in high deodorization. Has gained performance. Therefore, the gas passing through the deodorizing device 4 is heated by heat radiation from the PTC heater element 12 and the aluminum fin 11.

For example, FIG. 5 is a relationship diagram of the deodorizing performance and temperature of the catalyst used in the deodorizing apparatus according to Embodiment 1 of the present invention. When the catalyst is heated and the temperature of the catalyst exceeds around 60 ° C. (A), FIG. Activation begins and deodorization performance begins to increase. Furthermore, the deodorizing performance increases with increasing temperature from around the point where the temperature of the catalyst has passed around 100 ° C. (B), and the deodorizing performance is rapidly improved up to around 200 ° C. (C). And when the temperature of a catalyst exceeds 200 degreeC vicinity (C), the increase rate of the deodorizing performance with respect to a temperature rise will become small, and even if it raises temperature, deodorizing performance will not rise so much. Further, when the temperature of the catalyst rises to around 300 ° C. (D), the composition of the catalyst starts to change and its deodorizing performance decreases.
The catalyst can also adsorb oil smoke and water vapor, and the adsorbed oil smoke can be oxidized and decomposed by heating the temperature of the catalyst to a predetermined temperature (approximately 220 ° C.) or higher.
Further, when the amount of odor adsorbed by the catalyst in the same time is compared with the amount of odor decomposition that decomposes the odor adsorbed by the catalyst, the amount of odor adsorbed is generally larger.
Further, the relationship diagram shown in FIG. 5 is an example showing the relationship of the deodorizing performance with respect to the catalyst temperature, and the temperature zone, the increasing rate of the deodorizing performance, etc. vary depending on the type of the catalyst to be mixed and the mixing ratio. However, the effect that the deodorizing performance can be improved by heating the catalyst is obtained similarly. Similarly, the temperature at which the catalyst can decompose oil smoke also varies depending on the type and mixing ratio of the catalyst. Further, in order to obtain sufficient deodorizing performance even when the catalyst is at a low temperature, one or more kinds of adsorbents such as zeolite, activated carbon, silica gel, silicon oxide and the like that physically adsorb odorous substances in addition to the catalyst are used for the aluminum fin 11. You may use what was carry | supported to.

  Therefore, the present invention uses a catalyst that can be adsorbed and decomposed as a deodorizer for the deodorizer 4 and treats the contaminated components adsorbed by the deodorizer 4 by heating and activating the catalyst. As a result, even if the user does not perform maintenance on the deodorizing device 4, it is possible to obtain an air treatment device 100 that suppresses performance degradation due to changes over time and can maintain stable performance for a long period of time. In addition, in order to obtain a deodorizing performance sufficient to treat the contaminating component adsorbed by the catalyst, the catalyst deodorizing performance is improved by making the temperature of the catalyst faster and higher.

In the present invention, in order to make the temperature of the catalyst faster and higher, the PTC heater element 12 is brought into direct contact with the aluminum fin 11 carrying the catalyst to heat the catalyst by heat conduction. Thereby, since the heat of the PTC heater element 12 is efficiently conducted to the aluminum fins 11, the heat loss at the time of heating can be reduced. For example, the temperature of the catalyst can be increased to a higher temperature even with the same heating amount. Higher temperatures can be achieved and high deodorizing performance can be obtained. In addition, since there is little heat loss during heating, an energy saving effect can be obtained.
Further, in order to suppress the amount of heat of the PTC heater element 12 from escaping to the outside of the intake side air passage 8, a heat insulating material 14 made of a flame-retardant resin or the like is provided on the wall surface of the intake side air passage 8 in the vicinity of the PTC heater element 12. Is provided. As a result, the amount of heat escaping from the PTC heater element 12 to the outside of the intake side air passage 8 can be reduced, and the same effect as described above can be obtained. In addition, it is possible to prevent devices other than the air treatment device 100 provided inside the cabinet 101 (for example, the electric heating appliance 103 and a dishwasher (not shown)) from being unnecessarily heated and failing. In the first embodiment, the heat insulating material 14 is provided on the wall surface of the intake side air passage 8 in the vicinity of the PTC heater element 12, but the heat insulating material 14 suppresses the heat of the PTC heater element 12 from being transmitted to other than the aluminum fins 11. For example, a heat insulating material 14 is directly installed on the surface of the PTC heater element 12 other than the portion in contact with the aluminum fin 11 to suppress heat from being radiated to the surrounding air. Alternatively, conversely, the entire air treatment device 100 may be covered with the heat insulating material 14 to suppress the escape of heat to the outside of the air treatment device 100.
Moreover, since the PTC heater element 12 and the aluminum fin 11 are heated to a temperature exceeding 100 ° C., the air passing through the deodorizing device 4 is heated to a considerably high temperature. Therefore, the air passage around the deodorizing device 4 and the downstream side of the deodorizing device 4 is formed of a non-combustible material made of metal such as aluminum or stainless steel to prevent the fire from spreading due to temperature rise.

Next, the PTC heater element 12 used as a heater of the deodorizing apparatus 4 will be described. FIG. 6 is a characteristic diagram of the PTC heater element used in the deodorizing apparatus according to Embodiment 1 of the present invention.
The PTC heater element 12 used in the first embodiment is formed of an oxide semiconductor ceramic whose main component is barium titanate (BaTiO3), and its electric resistance exceeds 200 ° C. itself. It has an electrical characteristic that it suddenly increases when it comes, and it is configured so that the temperature of the PTC heater element 12 does not rise above 300 ° C. using this electrical characteristic. Therefore, by using the PTC heater element 12 as described above as a heater of the deodorizing device 4, for example, the suction port 1 is blocked by foreign matter, or the blower 3 is broken and stopped, so that the aluminum fin 11 or the PTC Even if the heat radiation from the heater element 12 is suppressed, the temperature of the PTC heater element 12 does not rise to 300 ° C. or higher, so that it is possible to reliably prevent a decrease in deodorizing performance due to a change in the composition of the catalyst. In addition, when the heater rises to an unexpected temperature, it is possible to prevent danger such as the spread of fire. For example, when a general heater represented by a sheathed heater is used instead of the PTC heater element, heater temperature detection means (not shown) for detecting the heater temperature is provided, and the heater temperature is detected by the heater temperature detection means. By controlling the energization of the heater so that it does not exceed 300 ° C., the same effect as when using the PTC heater element 12 can be obtained, but by using the PTC heater element 12, the heater temperature detecting means becomes unnecessary, The deodorization apparatus 4 can be comprised compactly.
In the first embodiment, barium titanate (BaTiO3) is used for the PTC heater element 12. For example, conductive particles such as carbon black and nickel dispersed in a low melting point polymer, crystals such as polyethylene, etc. A conductive polymer such as carbon black may be uniformly dispersed in the conductive polymer.

  In addition, although the aluminum fins 11 are evenly arranged in the first embodiment, since the wind speed near the center usually increases in the wind path, the aluminum fins 11 are densely arranged near the center of the wind path where the wind speed increases. You may arrange in. With the above configuration, the contaminated air 104 and the catalyst supported on the aluminum fin 11 can be efficiently contacted with each other, so that the deodorizing performance of the deodorizing device 4 can be improved and maintenance can be performed for a long time. The deodorizing performance of the catalyst necessary for making it unnecessary can be obtained.

FIG. 7 is a front view of a deodorizing apparatus different from the deodorizing apparatus according to Embodiment 1 of the present invention. Components having the same effects as those of the deodorizing apparatus according to Embodiment 1 are denoted by the same reference numerals.
As shown in FIG. 7, the deodorizing apparatus 4 may be configured such that the aluminum fin 11 carrying the catalyst is formed in a wave shape and connected to the PTC heater element 12. With the above configuration, the surface area of the aluminum fin 11 is increased, so that the contaminated air 104 and the catalyst supported on the aluminum fin 11 can be efficiently contacted with each other, so that the deodorizing performance of the deodorizing device 4 can be improved. Thus, the deodorizing performance of the catalyst necessary for making maintenance unnecessary for a long time can be obtained.

FIG. 8 is a cross-sectional view taken along the line AA of a cabinet incorporating an air treatment device using a deodorizing apparatus different from the deodorizing apparatus according to Embodiment 1 of the present invention. The deodorizing apparatus 4 is a deodorizing agent. And a heater that is installed in the vicinity of the deodorizing filter and heats the deodorizing filter with hot air or radiant heat. Components having the same effects as those of the deodorizing apparatus according to Embodiment 1 are denoted by the same reference numerals.
In the deodorizing apparatus 4 of FIG. 8, the PTC heater element 12 is installed on the windward side, and the deodorizing filter 15 is installed at a position facing the PTC heater element 12 on the leeward side. The deodorizing filter 15 is one in which a catalyst is supported on a base material in which the shape of the opening is formed in a corrugated shape. In addition, as the shape of the base material, a rectangular shape or a honeycomb shape is also used. As the base material, paper ceramic, cordierite, or metal is used. The base material is mainly composed of manganese oxide, and one of precious metals such as platinum, palladium, ruthenium, and rhodium or other metal oxides. A catalyst obtained by mixing the above is supported. Since the heater (PTC heater element 12) and the deodorizer (deodorization filter 15) are provided separately as described above, the processing for making the deodorizer and the heater in contact with each other is not necessary, so the processing is difficult. A material capable of improving the deodorizing performance can be used as the base material, and thereby the deodorizing performance necessary for making maintenance unnecessary for a long period of time can be obtained.

Next, a control circuit of the air treatment device in the first embodiment will be described. FIG. 9 is a control circuit schematic diagram of the air treatment device in the first embodiment.
The air treatment device 100 is provided with a control device 16 that controls the operation of the blower 3 and energization to the PTC heater element 12 by operating the switch 10. The control device 16 is provided with the air treatment device provided in the switch 10. The number of rotations of the blower 3 and the input of the PTC heater element 12 in response to an instruction from a switch that instructs operation / stop of 100 or a switch (for example, strong, medium, weak, etc.) that can designate the operation speed (air volume) of the blower 3 The power is controlled.

Next, the operation of the air treatment device in the first embodiment will be described. FIG. 10 is an operation flow diagram of the air treatment device when the user actually uses it.
First, the user operates the switch 10 of the air treatment device 100 to send a signal instructing the start of operation of the air treatment device 100 to the control device 16 (S1). Then, the control device 16 operates the blower 3 to start suction from the suction port 1, starts energization of the PTC heater element 12, generates heat, and causes the catalyst (deodorant) carried on the aluminum fin 11 to be smoked. Is activated by heating to 220 ° C. or higher so that it can be decomposed (S2).

Next, the user places the heating container 102 containing the object to be heated on the electric heater 103, and presses the power switch 103a provided on the electric heater 103 to turn it on (S3). To heat the heating container 102 and start cooking (S4). The object to be heated is cooked by the electric heater 103, and at that time, contaminated air 104 containing water vapor, oil smoke, odor and the like is generated. The generated contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3. The contaminated air 104 sucked from the suction port 1 is subjected to the removal of most of water vapor and oil smoke contained in the contaminated air 104 by the metal filter 6 installed in the suction port 4 and further flows through the intake side air passage 8. Odor contained in the contaminated air 104 is adsorbed by the catalyst supported on the aluminum fins 11 of the deodorizing apparatus 4, and water vapor and oil smoke not captured by the filter 6 are also adsorbed, so that the contaminated air 104 is purified. Thereafter, the purified air 105 passes through the blower 3, flows through the exhaust side air passage 9, and is discharged out of the cabinet 101 from the blowout port 5.
At this time, the catalyst is heated to a temperature of 220 ° C. or higher, and the catalyst is activated and exhibits a higher deodorizing performance than that at room temperature, adsorbs ambient odors and oxidizes and decomposes the adsorbed odors. Harmless, non-brominated and then released again. As a result, the catalyst can regenerate the deodorizing performance by itself, so that the sufficient deodorizing performance can be maintained for a long time without maintenance by the user. In addition, since the catalyst is heated to a temperature of 220 ° C. or higher, not only the odor but also the oily smoke can be decomposed, so that the deodorization performance of the catalyst can be maintained for a long period of time. become.

  When cooking is completed, the user presses the power switch 103a of the electric heater 103, turns off the power switch 103a, and stops the electric heater 103 (S5). Furthermore, the switch 10 of the air treatment device 100 is operated to send a signal for instructing to stop the operation of the air treatment device 100 to the control device 16 (S6). Thereby, the control apparatus 16 stops the driving | operation of the air blower 3, and the electricity supply to the PTC heater element 12 (S7).

In the first embodiment, the switch 10 is installed in the air treatment device 100. However, the switch 10 may be any device as long as it can issue an operation instruction for the air treatment device 100. For example, the switch 10 is provided separately from the air treatment device 100. It may be one using a remote control or the like. Further, the switch 10 may instruct the operation of the air treatment device 100 in conjunction with the power switch 103 a of the electric heater 103. In addition, a detection sensor (not shown) that can detect the presence or absence and the amount of contaminated air 104 is provided as the switch 10, and the operation / stop of the air processing device 100 is instructed by information from the detection sensor, or the operating speed of the blower 3. (Air volume) may be changed.
Further, the order of S1 and S3, S5 and S6 is not limited to this, as long as energization of the PTC heater element 12 is continued for a predetermined time from the end of cooking to promote activation of the catalyst. .
Moreover, although the temperature of the catalyst was raised to 220 ° C. or higher at which the oil smoke can be decomposed, it is not limited to this. If the filter 6 has sufficient oil smoke removal performance, the temperature of the catalyst will not be raised to 220 ° C. or higher. May be.

FIG. 11 is a diagram illustrating the acetaldehyde removal performance of the air treatment device according to Embodiment 1 of the present invention. The air treatment apparatus 100 was put in a box of 1 cubic meter, 10 ppm of acetaldehyde was put in the box, the air treatment apparatus 100 was operated, and the residual ratio of acetaldehyde in the box for each operation time was measured.
As a result, when the air treatment apparatus 100 was operated with the PTC heater element 12 energized and the aluminum fin 11 heated, the acetaldehyde removal rate in the box was 90% after 10 minutes of operation. Further, even when the measurement was performed again (second time), the acetaldehyde removal rate in the box was 90% after 10 minutes of operation, and no change was observed in the deodorization performance (heating deodorization 1, Heat deodorization 2).
Further, as a comparison object, when the air treatment apparatus 100 is operated without energizing the PTC heater element 12, the acetaldehyde removal rate in the box becomes 65% after 10 minutes of operation (first time at normal temperature in the figure). When the same measurement was performed again (second time), the acetaldehyde removal rate in the box was 50% after 10 minutes of operation (second time at room temperature in the figure). Thereafter, when the PTC heater element 12 was turned on again, the acetaldehyde removal rate in the box was 70% after 10 minutes of operation, and it was confirmed that the acetaldehyde removal rate recovered (after heating regeneration in the figure).
From the above results, it has been confirmed that sufficient deodorization performance can be maintained without maintenance of the deodorization apparatus 4 by heating the catalyst at a sufficient temperature and time. Therefore, it has been found that by using the air treatment device 100 of Embodiment 1, the user can maintain the stable performance for a long period of time without performing the maintenance of the deodorizing device 4, suppressing the performance deterioration due to the change with time.

FIG. 12 is a diagram comparing acetaldehyde removal performance depending on the type of catalyst used for the deodorizer in Embodiment 1 of the present invention.
FIG. 12 shows the measurement using the air treatment device 100 in which the PTC heater element 12 and the deodorizing filter 15 carrying the catalyst are separately formed as shown in FIG. The acetaldehyde removal rate calculated from the acetaldehyde concentration after passing through the deodorizing filter 15 and the acetaldehyde concentration before passing through the deodorizing filter 15 is measured by passing acetaldehyde of 10 ppm.
As a result, it can be confirmed that a catalyst in which a noble metal is mixed with manganese oxide has a better acetaldehyde removal rate than manganese oxide alone. Furthermore, it can be confirmed that the acetaldehyde removal rate is increased by heating the catalyst in which noble metal is mixed with manganese oxide to increase the temperature. It can also be confirmed that the acetaldehyde removal rate can be improved by raising the temperature of the catalyst from 100 ° C. to 200 ° C. Therefore, higher deodorization performance can be obtained by using a catalyst composed mainly of manganese oxide as a deodorizer and a mixture of one or more of noble metals such as platinum, palladium, ruthenium and rhodium or other metal oxides. You can see that

[Embodiment 2]
In addition to the air treatment device 100 shown in the first embodiment, the air treatment device 100 according to the second embodiment of the present invention includes a timer 17 that can measure the elapsed time in the control device 16 and changes its operation flow. A special effect is obtained. FIG. 13 is a schematic diagram of a control circuit of the air treatment device according to Embodiment 2 of the present invention, and FIG. 14 is an operation flow diagram of the air treatment device according to Embodiment 2 of the present invention. In the figure, the same reference numerals are given to portions having the same functions as those in the first embodiment. Hereinafter, an operation flow of the air treatment device 100 according to Embodiment 2 will be described.

First, the user operates the switch 10 of the air treatment device 100 to send a signal instructing the start of operation of the air treatment device 100 to the control device 16 (S1). Then, the control device 16 operates the blower 3 to start suction from the suction port 1, and starts energizing the PTC heater element 12 to generate heat, thereby causing the catalyst (deodorant) carried on the aluminum fin 11 to be 100. It is activated by heating to a temperature of from ℃ to 200 ℃ (S2).
Next, the user places the heating container 102 containing the object to be heated on the electric heater 103, and presses the power switch 103a provided on the electric heater 103 to turn it on (S3). To heat the heating container 102 and start cooking (S4).

The object to be heated is cooked by the electric heater 103, and at that time, contaminated air 104 containing water vapor, oil smoke, odor and the like is generated. The generated contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3. The contaminated air 104 sucked from the suction port 1 is subjected to the removal of most of water vapor and oil smoke contained in the contaminated air 104 by the metal filter 6 installed in the suction port 4 and further flows through the intake side air passage 8. Odor contained in the contaminated air 104 is adsorbed by the catalyst supported on the aluminum fins 11 of the deodorizing apparatus 4, and water vapor and oil smoke not captured by the filter 6 are also adsorbed, so that the contaminated air 104 is purified. Thereafter, the purified air 105 passes through the blower 3, flows through the exhaust side air passage 9, and is discharged out of the cabinet 101 from the blowout port 5.
At this time, the catalyst is heated and its temperature rises to 100 ° C. to 200 ° C., whereby the catalyst is activated and exhibits a higher deodorizing performance than at normal temperature, and adsorbs ambient odors and the like. At the same time, the adsorbed odor is oxidatively decomposed, harmless and brominated, and then released again. Therefore, when the air treatment apparatus 100 is operating, the catalyst performs a deodorizing action that adsorbs odors, oily smoke, water vapor, etc., and regenerates the deodorizing function by oxidizing and desorbing the adsorbed odors and releasing them again. Is going.

When cooking is completed, the user presses the power switch 103a of the electric heater 103, turns off the power switch 103a, and stops the electric heater 103 (S5). Further, the switch 10 of the air treatment device 100 is operated to send a signal for instructing to stop the operation of the air treatment device 100 to the control device 16 (S6). Then, the control device 16 reduces the rotational speed of the blower 3 while maintaining the energization of the PTC heater element 12 and shifts to the low speed operation to reduce the suction air volume, and starts recording the elapsed time by the timer 17 (S61). . Here, since the heat radiation amount of the aluminum fin 11 and the PTC heater element 12 decreases as the suction air amount from the suction port 1 decreases, the temperature of the catalyst carried on the aluminum fin 11 is higher than the temperature during cooking. The temperature rises to 220 ° C or higher. As a result, the catalyst starts decomposing the oily smoke adsorbed during cooking, changes it into harmless and odorless, and releases it again. Further, the deodorizing performance of the catalyst is further improved, and the decomposition rate of the already adsorbed odor is increased.
The reason why the blower 3 is operated at a low speed at this time is to supply the catalyst with air containing oxygen necessary for the oxidative decomposition of the catalyst. For example, instead of operating the blower 3 at a low speed, deodorization is performed. An opening (not shown) through which the outside air can flow is provided below the device 4 and air (oxygen) may be supplied to the catalyst using the rising air flow caused by the heat of the PTC heater element 12.

When the elapsed time of the timer 17 reaches a predetermined time set in advance, the control device 16 stops the operation of the blower 3 and energization of the PTC heater element 12 (S7).
Here, after operating the switch 10 to send a signal instructing to stop the operation of the air treatment device 100 to the control device 16 (S6), the heating of the blower 3 and the PTC heater element 12 is actually stopped (S7). This predetermined time may be set to a longer time, for example, to substantially decompose the odor adsorbed on the catalyst and the decomposition of oily smoke, and to reduce user discomfort and power consumption. In consideration of this, the setting time may be shortened. Further, a sensor for detecting the amount of adsorption adsorbed on the deodorant is provided, and a predetermined time is automatically set according to the result, or the sensor is used in place of the timer 17 to operate the blower 3 and energize the PTC heater element 12. (S7) The timing may be determined, or the user may set the predetermined time by himself / herself.

As described above, the air treatment device 100 according to Embodiment 2 of the present invention heats the catalyst for a predetermined time after cooking is finished and the operation of the switch 10 is instructed to stop the operation of the air treatment device 100 (S6 to S7). Sufficient time is provided to continuously decompose the odor adsorbed on the catalyst, so that a larger amount of odor generated during cooking (S3 to S5) than the odor that the catalyst decomposes. However, the odor adsorbed on the catalyst can be decomposed until sufficient deodorization performance is obtained until the next time the air treatment device 100 is used, and stable deodorization performance can be maintained for a long time. In addition, the above-described effect is obtained by energizing the PTC heater element 12 and the fan 3 for a predetermined time without shifting the blower 3 to the low speed operation for a predetermined time after the operation stop operation by the switch 10 as shown in the second embodiment. Obtained by maintaining driving.
Further, the deodorizing apparatus 4 according to the second embodiment does not need to be activated by heating the catalyst to a high temperature so as to decompose all odors generated during cooking as in the first embodiment. The heater having a smaller heating capacity than the heater of the first embodiment may be used, so that the deodorizing device 4 can be made compact, and the temperature of the purified air 105 discharged from the outlet 5 during cooking is lowered. User discomfort caused by hot air can be reduced.
Further, since the air blower 3 needs to generate a considerable air volume in order to suck the contaminated air 104 during cooking, the amount of heat released from the aluminum fins 11 and the PTC heater element 12 during cooking is large. In order to raise the temperature to 220 ° C. or higher where decomposition can be performed, it is necessary to suppress the amount of suction air during cooking to some extent or to use a heater having a very high heating power that generates heat up to 300 ° C. or higher. However, the amount of heat released from the aluminum fin 11 and the PTC heater element 12 is greatly increased by operating so as to decompose the oil smoke adsorbed on the catalyst after cooking, which is not under cooking and does not require a large suction air volume as in the second embodiment. The amount of suction air during cooking can be reduced, and sufficient deodorization performance can be stably maintained for a long period of time without using a heater with a very high heating power.

The heating container 102 is heated to start cooking (S4). The object to be heated is cooked by the electric heater 103, and at that time, contaminated air 104 containing water vapor, oil smoke, odor and the like is generated. The generated contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3.

FIG. 16 is a cross-sectional view taken along line AA of the cabinet incorporating the air treatment device according to Embodiment 4 of the present invention. In addition, in the figure, the same code | symbol is attached | subjected to the part which has the same function as Embodiment 1-2. In the fourth embodiment, the cooling means according to the third embodiment is different from the first embodiment, and hereinafter, the fourth embodiment will be described with a focus on differences from the third embodiment.
The air treatment apparatus 100 according to the fourth embodiment of the present invention is a cooling unit that cools the air discharged from the blow-out port 5, and moves the heat from one side to the other side to simultaneously perform heating and cooling. The Peltier element 19 includes a cooling surface 20 to be cooled by the Peltier element 19, an exhaust side air passage 9 downstream from the blower 3, and a heat radiating surface 21 to which heat is radiated by the Peltier element 19. 4 is provided in the intake side air passage 8 upstream of the cooling plane 20, and includes a cooling fin 20 a on the cooling surface 20 side and a radiation fin 21 a on the radiation surface 21 side. By installing the Peltier element 19 as described above, the heat of the exhaust side air passage 9 is exchanged with the intake side air passage 8. The Peltier material 19 can control the amount of heat transferred by energizing the cooling surface 20 and the heat radiating surface 21, and this energization is turned ON / OFF in conjunction with the operation of the blower 3. Further, in FIG. 16, the cooling surface 20 of the Peltier element 19 is provided on the exhaust side air passage 9 side downstream from the blower 3, but is not limited thereto, and is downstream from the deodorizing device 4 and upstream from the outlet 5. It can be installed on either side. The heat exchange device is not limited to the one using the Peltier element 19, and may be a heat exchanger, a heat pump, or an aluminum material having fins on both sides of the intake side air passage 8 and the exhaust side air passage 9.

Next, the operation of the air treatment device according to Embodiment 4 of the present invention will be described. The operation flow is similar to the third embodiment, and the same effect can be obtained in both the first and second operation flows. Here, the operation flow diagram of the air treatment device in the first embodiment is shown in FIG. The difference between the fourth embodiment and the third embodiment will be mainly described with reference to FIG.
First, the user operates the switch 10 of the air treatment device 100 to send a signal instructing the start of operation of the air treatment device 100 to the control device 16 (S1). Then, the control device 16 operates the blower 3 to start suction from the suction port 1, starts energization to the PTC heater element 12, generates heat, and causes the catalyst (deodorant) carried on the aluminum fin 11 to be generated. The oily smoke is heated and activated so that it can be decomposed to 220 ° C. or higher (S2). Here, energization of the Peltier element 19 is also started.

  Next, the user places the heating container 102 containing the object to be heated on the electric heater 103, presses the power switch 103a provided on the electric heater 103 to turn it on (S3), and turns the electric heater 103 on. The heating container 102 is operated to start cooking (S4). The object to be heated is cooked by the electric heater 103, and at that time, contaminated air 104 containing water vapor, oil smoke, odor and the like is generated. The generated contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3. The polluted air 104 sucked from the suction port 1 flows through the intake side air passage 8 after most of the water vapor and oil smoke contained in the polluted air 104 are removed by the metal filter 6 installed in the suction port 4. The Peltier element 19 is heated when passing through the vicinity of the heat dissipating fins 21a provided on the heat dissipating surface 21 side, and then reaches the deodorizing device 4 and is supported on the aluminum fin 11 of the deodorizing device 4 (deodorizing agent). ), The odor, water vapor and oily smoke contained in the contaminated air 104 are adsorbed, and the contaminated air 104 is purified.

Here, the purified air 105 that has passed through the deodorizing device 4 is heated to a high temperature by the heat radiation from the heat radiation fins 21a and the heat radiation from the aluminum fins 11 and the PTC heater elements 12 heated to a high temperature. The purified air 105 flows through the exhaust side air passage 9 after passing through the blower 3, and passes through the vicinity of the cooling fin 20 a connected to the cooling surface 20 of the Peltier element 19 provided in the exhaust side air passage 9. Then, it is discharged from the outlet 5 to the outside of the cabinet 101.
As described above, by providing the heat exchange device that exchanges the heat of the exhaust side air passage 9 to the intake side air passage 8, the same effect as in the third embodiment can be obtained, and the purified air 105 Is forcibly cooled by the Peltier element 19, so that the temperature of the air discharged from the outlet 5 can be made lower than in the third embodiment, so that discomfort felt by the user can be further reduced. In addition, since the contaminated air 104 is heated on the upstream side of the deodorizing device 4, the amount of heat released from the aluminum fins 11 and the PTC heater element 12 can be reduced, and the catalyst can be heated faster and at a higher temperature. . Thereby, the deodorizing performance of the catalyst can be improved, and thereby sufficient deodorizing performance can be maintained for a long time without maintenance. Further, since the amount of heat radiation is reduced, even when heating to the same temperature, the energization to the PTC heater element 12 is small, and the energy saving effect by this can be obtained.

FIG. 19 is a control circuit schematic diagram of the air treatment device according to the fifth embodiment of the present invention. In the figure, parts having the same functions as those in the first to fourth embodiments are denoted by the same reference numerals. In the following, the fifth embodiment will be described focusing on the differences from the second embodiment.
The air treatment device 100 according to Embodiment 5 of the present invention communicates the air outlet shutter 22 that can open and close the air outlet 5, the intake side air passage 8 upstream from the deodorizing device 4, and the exhaust side air passage 9 downstream from the blower 3. And a communication port shutter 24 that can open and close the communication port 23 and that blocks communication between the suction port 1 and the deodorizing device 4 when the communication port 23 is open. The opening and closing of the outlet shutter 22 and the communication port shutter 24 is controlled by the control device 16. Further, the communication port shutter 24 has two functions of opening / closing the communication port 23 and blocking the communication between the suction port 1 and the deodorizing device 4, but a shutter that performs each function may be provided separately.

Next, the operation of the air treatment device according to Embodiment 5 of the present invention will be described. FIG. 20 is an operation flowchart of the air treatment device according to Embodiment 5 of the present invention.
First, the user operates the switch 10 of the air treatment device 100 to send a signal instructing the start of operation of the air treatment device 100 to the control device 16 (S1). Then, the control device 16 opens the outlet shutter 22 to allow ventilation outside the exhaust side air passage 9 and the cabinet 101. In addition, the communication port shutter 24 is closed to close the communication port 23, and the suction port 1 and the deodorizing device 4 can be ventilated (S11). After that, the control device 16 operates the blower 3 to start suction from the suction port 1, and starts energization of the PTC heater element 12 to generate heat to cause the catalyst (deodorant) carried on the aluminum fin 11 to be generated. It heats and activates so that it may become 100 to 200 degreeC (S2).
Next, the user places the heating container 102 containing the object to be heated on the electric heater 103, and presses the power switch 103a provided on the electric heater 103 to turn it on (S3). To heat the heating container 102 and start cooking (S4).

The object to be heated is cooked by the electric heater 103, and at that time, contaminated air 104 containing water vapor, oil smoke, odor and the like is generated. The generated contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3. The contaminated air 104 sucked from the suction port 1 is subjected to the removal of most of water vapor and oil smoke contained in the contaminated air 104 by the metal filter 6 installed in the suction port 4 and further flows through the intake side air passage 8. Odor contained in the contaminated air 104 is adsorbed by the catalyst supported on the aluminum fins 11 of the deodorizing apparatus 4, and water vapor and oil smoke not captured by the filter 6 are also adsorbed, so that the contaminated air 104 is purified. Thereafter, the purified air 105 passes through the blower 3, flows through the exhaust side air passage 9, and is discharged out of the cabinet 101 from the blowout port 5.
At this time, the catalyst is heated and its temperature rises to 100 ° C. to 200 ° C., whereby the catalyst is activated and exhibits a higher deodorizing performance than at normal temperature, and adsorbs ambient odors and the like. At the same time, the adsorbed odor is oxidatively decomposed, harmless and brominated, and then released again. Therefore, when the air treatment apparatus 100 is operating, the catalyst performs a deodorizing action that adsorbs odors, oily smoke, water vapor, etc., and regenerates the deodorizing function by oxidizing and desorbing the adsorbed odors and releasing them again. Is going.

When cooking is completed, the user presses the power switch 103a of the electric heater 103, turns off the power switch 103a, and stops the electric heater 103 (S5). Further, the switch 10 of the air treatment device 100 is operated to send a signal for instructing to stop the operation of the air treatment device 100 to the control device 16 (S6). Then, the control device 16 reduces the rotational speed of the blower 3 while maintaining the energization of the PTC heater element 12 and shifts to the low speed operation to reduce the suction air volume, and starts recording the elapsed time by the timer 17 (S61). . Further, the control device 16 closes the outlet shutter 22 to block the exhaust from the outlet 5 to the outside of the cabinet 101. In addition, the communication port shutter 24 is opened to block intake air from the suction port 1, and the communication port 23 can be ventilated to form a circulation air passage that circulates between the deodorizing device 4 and the blower 3 (S62). By forming the circulation air passage including the deodorizing device 4, the gas that has become hot due to the heat radiation of the aluminum fins 11 and the PTC heater element 12 is not discharged outside the circulation air passage (that is, discharged outside the air treatment device 100). The temperature gradually increases, and as a result, the heat dissipation of the aluminum fin 11 and the PTC heater element 12 decreases, and the temperature of the catalyst supported on the aluminum fin 11 is 220 ° C. or higher, which is higher than the temperature during cooking. The temperature rises to As a result, the catalyst starts decomposing the oily smoke adsorbed during cooking, changes it into harmless and odorless, and releases it again. Further, the deodorizing performance of the catalyst is further improved, and the decomposition rate of the already adsorbed odor is increased. Further, in the fifth embodiment, since hot air is not discharged from the outlet 5, it is possible to prevent the user from feeling uncomfortable or unnecessarily raising the indoor temperature.
When the elapsed time of the timer 17 reaches a predetermined time set in advance, the control device 16 stops the operation of the blower 3 and energization of the PTC heater element 12 (S7).

  As described above, in addition to the configuration and the operation flow of the second embodiment, the air treatment device 100 according to the fifth embodiment of the present invention instructs the stop of the operation of the air treatment device 100 by operating the switch 10 after cooking is finished. Later (S6 to S7) By forming a circulation air passage in the air treatment device 100, in addition to the effect obtained by the second embodiment, hot air is not discharged from the outlet 5, so that the user feels uncomfortable. It is possible to prevent the indoor temperature from being raised unnecessarily.

  The present invention sucks and purifies the contaminated air 104 containing at least odor generated by the use of equipment such as an electric heater 103 provided outside the air treatment apparatus 100 without combustion, and the purified air 105 is again purified. For example, instead of the electric heating apparatus 103, the air treatment apparatus 100 can be used as an air treatment apparatus 100 that sucks and purifies odors generated by soldering work or dyeing work. In the first to fifth embodiments, a part of the air treatment device 100 is installed in the cabinet 101. However, the present invention is not limited to this. For example, the air treatment device 100 is installed above the electric heater 103. May be. The air treatment device 100 is arranged in the order of the filter 6, the deodorizing device 4, and the blower 3, but is not limited to this, and the contaminated air 104 is sucked from the suction port 1 by the suction flow generated by the blower 3. As long as it can be purified by the filter 6 and the deodorizing device 4, they may be installed in any order.
