Description

  The present invention relates to an air cleaning equipment for purifying air, and more particularly to an air cleaning equipment having a gas adsorption filter that is assumed to be regenerated by heating.

  In general, it is desirable that the gas adsorption filter mounted on equipment such as air cleaning equipment should have adsorption performance for a wide variety of gases, and can be regenerated by heating assuming long-term use. Is desirable. When the deodorizing function of the filter is mainly considered, examples of the target gas include sulfur compounds, nitrogen compounds, aldehydes, aromatic hydrocarbons, fatty acids, ketones, esters, and the like. As a filter that realizes a deodorizing function for various gases as described above, it is common to use activated carbon in which pores of various sizes are mixed. However, activated carbon desorbs odor components by heating and the like. Since it cannot be disassembled, it is difficult to use multiple times. In order to deal with such problems, the conventional technology improves the adsorption performance by mixing and adsorbing a highly active manganese compound such as manganese dioxide and an inorganic adsorbent such as zeolite, and oxidative decomposition performance during heating. It has been proposed to use a deodorizing filter with an improved value (for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-137591

  However, when the conventional deodorizing filter described in Patent Document 1 is applied to air cleaning equipment, the following problems arise. That is, in a general deodorization catalyst, in order to heat acetaldehyde, which is one of odor components generated in cooking at home, for example, to decompose it into harmless carbon dioxide, a high temperature of 140 ° C. or higher is required. . On the other hand, the casing of home appliances is made of a plastic that is highly fluid and easy to mold, such as PP, PS, PET, ABS, and the like. When these plastics are heated above 100 ° C., they often deteriorate such as deformation and discoloration.

  For this reason, when a conventional deodorizing filter is mounted on an air purification equipment, a special structure is required to shield the heated part of the filter with metal or to insulate the heated part. However, there is a problem of increasing the size and weight. In addition, in the air cleaning equipment, it is difficult to avoid temperature unevenness during heating due to the configuration of the product. For this reason, if it is going to heat the whole reproduction | regeneration location of a deodorizing filter to 140 degreeC or more, there exists a possibility of causing an overheating state locally and causing the ignition of the gas component adsorbed by the filter. On the other hand, if an attempt is made to avoid an overheated state, a low-temperature site where gas components are not completely decomposed is generated, and harmful gases such as acetic acid and carbon monoxide may be released to the outside from this site.

  The present invention has been made in order to solve the above-described problems, and has a function of decomposing odor gas even at a low temperature, and a deodorizing filter that can be regenerated in a low temperature range even if there is temperature unevenness. An object is to provide a small and lightweight air purifying equipment.

The deodorizing filter includes an adsorbent containing at least zeolite and manganese oxide having an OMS-2 structure.

  According to the present invention, it is possible to realize a deodorizing filter that has a function of decomposing odor gas even at a low temperature and can be regenerated in a low temperature range even if there is temperature unevenness, and is equipped with such a deodorizing filter. Thus, it is possible to provide a small and lightweight air cleaning equipment.

FIG. 10A is a perspective view of the heating unit as viewed from the rear, and FIG. 10B is a perspective view of the heating unit as viewed from the front.

  As shown in FIGS. 9 and 10, the heating unit 63 includes a heater unit 63a as a heater and a unit case 63b as a heater holding portion. The heater unit 63a is a heating unit that heats the deodorizing filter 62, and is housed inside the unit case 63b. The heater unit 63a is formed in a fan shape that is slightly smaller than the lid 65d of the middle partition plate 65, and in a state facing the lid 65d with the deodorizing filter 62 interposed therebetween, Arranged at overlapping positions. The heater unit 63 a is electrically connected to the control unit 47, and the heat generation amount of the heater unit 63 a is controlled according to the energized state from the control unit 47.

  Further, as shown in FIG. 9, the heater unit 63a includes a heating element 63f formed of a fan-shaped flat plate and, for example, two heater elements 63g attached to the rear surface portion of the heating element 63f. The heating element 63f is heated by the heater element 63g. The front surface portion of the heat generating body 63f is a portion facing the lid body 65d of the intermediate partition plate 65 with the deodorizing filter 62 interposed therebetween, and this front surface portion is provided to improve the emissivity of heat received from the heater element 63g. For example, a black heat-resistant coating is applied. Accordingly, the heater unit 63a radiates the heat generated by the heater element 63g from the entire plate-like heating element 63f toward the deodorization filter 62, thereby efficiently reducing the portion of the deodorization filter 62 that faces the heater unit 63a. Heating well can suppress uneven heating of the deodorizing filter 62.

  The heater element 63g is composed of, for example, a PTC heater which is a semiconductor ceramic mainly composed of barium titanate. The PTC heater has self-temperature controllability and does not require temperature control from the outside. Therefore, the PTC heater can be used at a stable temperature without performing intermittent control unlike a thermostat. When the heater unit 63a faces the lid body 65d of the intermediate partition plate 65 with the deodorizing filter 62 interposed therebetween, a gap with a predetermined dimension is formed between the heating element 63f and the deodorizing filter 62. In this state, the heater unit 63a has a function of heating a portion of the deodorizing filter 62 facing the heating element 63f to a prescribed temperature by being energized for a predetermined time. Here, the specified temperature is a temperature at which the odor component adsorbed by the deodorizing filter 62 can be removed.

The unit case 63b includes a recessed portion 63c that holds the heater unit 63a inside, and a flange portion 63d that protrudes outward from the opening periphery of the recessed portion 63c. The concave portion 63 c is formed in a fan shape corresponding to the outer shape of the heater unit 63 a and opens at a position facing the deodorizing filter 62. The flange portion 63d is formed with a plurality of screw holes 63e through which screws for fixing the unit case 63b are inserted.

  Next, the drive mechanism 64 will be described with reference to FIG. The drive mechanism 64 changes the relative positional relationship between the heating unit 63 and the deodorizing filter 62, thereby changing position changing means for changing the heating target portion of the deodorizing filter 62 that the heating element 63f of the heating unit 63 faces. It is composed. The drive mechanism 64 includes a motor 64a and a bracket 64b that holds the motor 64a. A drive gear is fixed to the rotation shaft of the motor 64a, and this drive gear is configured to mesh with the gear portion 62b of the deodorizing filter 62. The motor 64 a is electrically connected to the control unit 47, and the rotation angle is controlled by the control unit 47. Thereby, the drive mechanism 64 rotates the deodorizing filter 62 around the shaft 65j of the partition plate 65, and moves all parts of the deodorizing filter 62 to positions facing the heater unit 63a according to the rotation angle. Can do.

  Next, assembly of the deodorizing unit 60 will be described with reference to FIGS. 4, 7, and 8. When the deodorizing unit 60 is assembled, the deodorizing unit 60 is assembled by attaching the deodorizing filter 62, the heating unit 63, and the drive mechanism 64 to the frame body 61 so that the state shown in FIG. 8 is changed to the state shown in FIG. Specifically, first, the lid body 65d is attached to the partition plate 65 of the frame body 61, and then the deodorizing filter 62 is fitted from the rear surface side of the frame body 61 to the inner peripheral side of the guide portion 65e. The shaft 65j of the frame body 61 is fitted into the opening 62c of the 62.

  Next, each filter holding part 65f is attached to the guide part 65e from the rear surface side of the deodorizing filter 62. Thereby, the deodorizing filter 62 is held between the filter holding surface 65k and each filter holding portion 65f at a position facing the opening 65a of the intermediate partition plate 65, and is attached to the frame body 61. In this state, the filter holding surface 65k and the filter holding portion 65f position the deodorizing filter 62 with respect to the axial direction with such a gentleness that does not hinder the rotation of the deodorizing filter 62. The “axial direction” is the extending direction of the shaft 65j and corresponds to the front-rear direction of the air conditioner 1.

  In the next process, the heating unit 63 is attached to the frame body 61 at a predetermined position (the sector area) that covers a part of the deodorizing filter 62. At this time, the heating unit 63 is screwed to the center support body 65 b exposed at the position of the opening 62 c of the deodorizing filter 62 and an attachment portion formed on the partition plate 65 outside the deodorizing filter 62. Accordingly, the heating element 63f of the heater unit 63a constituting the heating unit 63 is opposed to the deodorizing filter 62 in the axial direction in the fan-shaped region, and is opposed to the lid 65d in the axial direction with the deodorizing filter 62 interposed therebetween. It becomes. That is, a part of the deodorizing filter 62 is placed in a heating space formed between the heating unit 63 and the lid body 65d. In this state, axial gaps having appropriate dimensions are secured on both sides of the deodorizing filter 62.

  As a result, the deodorizing filter 62 can rotate about the shaft 65j of the partition plate 65, and the portion of the deodorizing filter 62 that faces the heating element 63f and the lid 65d changes according to the rotation angle of the deodorizing filter 62. Configured to do. In the present embodiment, the case where the deodorizing filter 62 is configured to be rotatable by fitting the shaft 65j of the frame 61 into the opening 62c of the deodorizing filter 62 has been exemplified. However, in the present invention, the opening 62c and the shaft 65j are not necessarily provided. For example, an annular groove or the like is provided on the inner peripheral side of the guide part 65e of the intermediate partition plate 65, and the deodorizing filter 62 is held by the groove. The deodorizing filter 62 may be configured to be rotatable.

  Thus, in the present embodiment, a part of the deodorizing filter 62 can be disposed in the heating space formed between the heating unit 63 and the lid 65d facing each other, and heat is accumulated in the heating space. A part of the deodorizing filter 62 can be efficiently heated. When the heating element 63f and the lid 65d of the heating unit 63 are coated to improve the heat emissivity, the heat generated by the heater element 63g is efficiently radiated to the heating space, and the deodorizing filter 62 Heating can be performed more efficiently. Thus, the heating unit 63 is configured to efficiently heat the portion of the deodorizing filter 62 that is disposed in the heating space.

  On the other hand, the drive mechanism 64 is attached to the rear surface portion of the intermediate partition plate 65 in a state where the motor 64a is fixed to the bracket 64b. In FIG. 8, this attachment position is, for example, a position between the opening 65a and the corner 65g of the middle partition plate 65. In this state, the drive gear of the motor 64a is meshed with the gear portion 62b of the deodorizing filter 62. Thereby, when the drive mechanism 64 is disposed, the dead space generated in the vicinity of the corner 65g can be effectively utilized around the opening 65a of the rectangular partition plate 65. The drive mechanism 64 is preferably mounted between any one of the four corners 65g provided in the middle partition plate 65 and the opening 65a. Thereby, the heating unit 63 and the drive mechanism 64 can be arranged separately from the lower side and the upper side with respect to the center of the opening 65a, and the heat generated by the heating unit 63 is prevented from affecting the drive mechanism 64. Can do.

  Next, the assembly of the air conditioner 1 will be described with reference to FIG. When the air conditioner 1 is assembled, first, the rear case 40 with the front opening 41 facing forward is attached to the rear side of the front case 20. At this time, the fan opening 44d of the blower fan 44 attached to the rear case 40 and the rear opening 24 formed in the partition plate 23 of the front case 20 are arranged to overlap each other in the front-rear direction. The opening center of the rear opening 24 is arranged coaxially with the rotation axis of the blower fan 44.

  Next, the deodorizing part 60 is attached to the front case 20 by inserting the frame 61 of the deodorizing part 60 into the front opening 22 of the front case 20 and fitting the outer periphery of the frame 61 into the front case 20. As described above, in a state where the deodorizing unit 60 is attached to the front case 20, the rear surface side (heating unit 63 side) of the deodorizing unit 60 is disposed so as to face the rear opening 24 of the front case 20. A heating unit 63 is disposed between the openings 24. In this state, the partition plate 23 and the rear opening 24 that form a bell mouth around the fan opening 44d of the blower fan 44, and the deodorizing filter 62, as shown in FIG. Are arranged so as to face each other. This interval D is formed so as not to hinder the flow of air flowing from the deodorizing filter 62 to the rear opening 24. The heating unit 63 is disposed in a space corresponding to the interval D formed in this way.

  In the next process, the HEPA filter 12 and the pre-filter 13 are arranged inside the frame body 61 of the deodorizing unit 60. Then, on the front side of the pre-filter 13, the front panel 10 is attached so as to be sandwiched between the upper protruding portion 28 and the lower protruding portion 25 of the front case 20. Thereby, the air conditioner 1 can be assembled. It should be noted that the above description of the assembly describes only main parts.

(Air cleaning operation)
Next, a normal air cleaning operation executed by the air conditioner 1 will be described with reference to FIG. First, when the user performs a predetermined operation using the operation unit 26, the control unit 47 starts the air cleaning operation by operating the blower fan 44. Thereby, indoor air is sucked in from the suction port 11, and this air is purified while circulating along the air path R shown in FIG. More specifically, the air sucked from the suction port 11 first sequentially passes through the prefilter 13 and the HEPA filter 12. As a result, large dust in the air is removed by the pre-filter 13, and small dust is removed by the HEPA filter 12.

  The air that has passed through the HEPA filter 12 flows into the deodorizing unit 60 and passes through the deodorizing filter 62. When the air passes through a large number of openings formed in the honeycomb core of the deodorizing filter 62, the air comes into contact with the catalyst applied to the wall surface of each opening. Therefore, if an odor component is contained in the air, the odor component is adsorbed by the catalyst and removed from the air. Note that “removing odor components in the air with the deodorizing filter 62” means at least reducing the odor components in the air, and includes a state in which the odor components are not completely removed.

  Next, the air that flows out from the deodorizing unit 60 flows into the blower fan 44 via the rear opening 24 of the front case 20 and is sucked into the fan opening 44 d from the front side of the blower fan 44. The air is blown in the radial direction from the outer peripheral side of the blower fan 44 and then guided to the upper portion of the rear case 40 by the partition member 45. And it passes through the louver 46 and is blown out into the room from the blower outlet 42 upward in a state where the wind direction is adjusted. Thus, according to the air cleaning operation, dust and odor components contained in the indoor air can be removed, and the air can be purified.

  As described above, the air conditioner 1 according to the present embodiment extends in the horizontal direction from the suction port 11 opened in the front surface of the casing 2 toward the partition member 45 on the rear side, and faces upward at the position of the partition member 45. And a wind path R leading to the air outlet 42 is provided. In the air path R, a dust filtration filter including the prefilter 13 and the HEPA filter 12 is disposed on the upstream side of the deodorizing filter 62 with reference to the air flow. Further, the air passage R is bent upward from the horizontal direction on the downstream side of the deodorizing filter 62, and a blower fan 44 made of a sirocco fan is disposed at a bent portion of the air passage R.

  Since the sirocco fan blows out the air sucked in from the axial direction of the fan in the radial direction, it forms a linear flow of sucking indoor air backward from the front surface of the casing 2, and this air flow direction is defined by the air outlet 42. Can be changed efficiently. Further, the front surfaces of the deodorizing filter 62, the pre-filter 13, the HEPA filter 12, and the fan opening 44 d of the blower fan 44 are arranged perpendicular to the flow direction of the air flowing through the air path R. Thereby, since the flow of air is straight to the deodorizing filter 62 and the air passes perpendicularly to each of the filters 12, 13, 62, air can be sucked and filtered efficiently.

  Here, the opening 65 a of the middle partition plate 65 is disposed at the center in the vertical direction when viewed from the front of the casing 2. And the front view WHEREIN: The relationship between the projection area X of the casing 2 and the projection area Y of the opening 65a is comprised so that the following (1) Formula may be satisfy | filled. Thereby, the opening area of the opening 65 a can be sufficiently secured with respect to the size of the casing 2, and air can be efficiently circulated in the casing 2.

Y ≧ 0.6X (1)

(Filter regeneration operation)
On the other hand, when the air cleaning operation is performed, the adsorbed odor component is accumulated in the deodorization filter 62, and the deodorization performance of the deodorization filter 62 decreases as the accumulation amount of the odor component increases. For this reason, the control unit 47 executes a filter regeneration operation for recovering the deodorizing performance of the deodorizing filter 62. Hereinafter, the filter regeneration operation will be described.

  The filter regeneration operation is executed by the control unit 47 at a predetermined timing. This timing is, for example, the cumulative operation time since the start of the air cleaning operation, or the cumulative operation time of the air cleaning operation after the end of the previous filter regeneration operation has exceeded the preset regeneration required time. This is the case. More specifically, for example, it is preferable to perform the filter regeneration operation once or more in 24 hours.

  In the filter regeneration operation, first, the heating unit 63 is energized in the state where the air cleaning operation is finished and the blower fan 44 is stopped. Thereby, the part which opposed the heating unit 63 among the deodorizing filter 62 is heated, and the temperature of this part is kept in the state raised to the specified temperature. This state is continued for a specified time. The specified temperature and the specified time at this time are obtained, for example, by actual measurement, and are set to values sufficient to remove the odor component adsorbed by the deodorizing filter 62. Here, there is a temperature difference between the temperature of the heating unit 63 and the temperature of the deodorizing filter 62 due to air or the like existing between the two. In consideration of this, it is necessary to set the deodorizing filter 62 to a value sufficient to regenerate. Specific temperature control will be described later.

  Here, as described above, the heating target portion of the deodorizing filter 62 is heated while being covered from both sides by the heating element 63f and the lid body 65d that have been coated to increase the emissivity of heat. Thereby, the deodorizing filter 62 can be efficiently heated by the heat generated from the heater unit 63a and the heat radiated from the lid body 65d. Further, the heat released from the heating element 63f and the lid 65d can be stored in a narrow heating space between them. As a result, the heating efficiency of the deodorizing filter 62 disposed in the heating space can be further increased.

  After the partial regeneration of the deodorizing filter 62 is completed by the above heat treatment, the controller 47 energizes the motor 64a of the drive mechanism 64 to operate the drive mechanism 64. As a result, the driving force of the motor 64a is transmitted to the deodorizing filter 62 via the driving gear and the gear portion 62b, and the deodorizing filter 62 rotates around the shaft 65j of the partition plate 65. The deodorizing filter 62 is rotated by the unit movement angle.

  Here, the unit movement angle means that a part of the deodorizing filter 62 that has been subjected to the heating process moves in a rotational direction from a position facing the heating unit 63, and a new part that has not been subjected to the heating process is connected to the heating unit 63. This is the angle to move to the facing position. The unit movement angle is preferably set to coincide with the central angle of the heater unit 63a formed in a fan shape around the shaft 65j, or set to an angle smaller than the central angle of the heater unit 63a.

  As described above, the present embodiment includes the drive mechanism 64 that changes the relative positional relationship between the deodorizing filter 62 and the heating unit 63 by rotating the deodorizing filter 62. Thereby, in the filter regeneration operation, the deodorizing filter 62 can be rotated once by the drive mechanism 64 while the deodorizing filter 62 is partially heated by the heating unit 63. Thereby, heat processing can be performed with respect to the whole deodorizing filter 62, and the whole deodorizing performance can be reproduced | regenerated. In the filter regeneration operation, the timing for rotating the deodorizing filter 62 may be immediately after the completion of the heat treatment for one part, or immediately before the air cleaning operation that is performed first after the heat treatment for the part is completed. It may be.

  Next, with reference to FIG. 11, the heating control when heating the deodorizing filter 62 will be described. FIG. 11 is a characteristic diagram showing the temperature characteristics of the deodorizing filter realized by the filter regeneration operation in the first embodiment of the present invention. In the heating control, in order to efficiently recover the performance of the deodorizing filter 62, the heating operation by the heating unit 63 is performed intermittently. That is, in the heating control, the temperature of the deodorizing filter 62 is raised to the above-mentioned specified temperature α, but at the set temperatures a and b in the middle, the energization to the heating unit 63 is temporarily stopped and the heating is interrupted. The set temperatures a and b are set as temperatures lower than the specified temperature α, and the heating interruption time at the set temperatures a and b is set to, for example, about 4 and 5 minutes.

  When the temperature of the deodorizing filter 62 reaches the set temperatures a and b and the heating is interrupted, the temperature is detected by, for example, a temperature detecting means (not shown) arranged in the heating unit 63 and the heating unit 63 is suddenly changed. Make sure that there is no temperature rise. Here, “rapid temperature rise” means, for example, the rate of temperature rise detected by the temperature detecting means when the rate of temperature rise due to heating of the heater unit 63a is a reference rate of about 3 to 5 ° C. per 10 seconds. Means that the speed exceeds the reference speed.

  Since the deodorizing filter 62 is heated by the heater unit 63a, normally, a certain amount of temperature increase may occur due to residual heat after the energization to the heater unit 63a is stopped, but a reference speed temperature increase may not occur. it is conceivable that. Accordingly, when a sudden temperature rise is detected, the heating unit 63 is immediately stopped to end the filter regeneration operation, and an error message is transmitted to notify the user of the abnormality. On the other hand, when a rapid temperature rise is not detected, resumption of energization to the heater unit 63a is permitted.

  Then, after the temperature of the deodorizing filter 62 reaches the specified temperature α, a process of intermittently energizing the heater unit 63a is performed while monitoring the occurrence of a rapid temperature increase. This process is continued until the above-mentioned specified time t has elapsed. The length of the specified time t is set based on, for example, the usage environment of the air conditioner 1, the temperature, the odor component to be deodorized, whether or not the catalyst is attached to the deodorizing filter 62, the type of catalyst, and the like. The measurement is started from the starting point of the heating control or the reaching point of the specified temperature α.

  Next, with reference to FIG. 12, the specific process of the heating control performed in each part of the deodorizing filter 62 during the filter regeneration operation will be described. FIG. 12 is a flowchart showing an example of heating control for heating and regenerating the deodorizing filter in Embodiment 1 of the present invention. In the heating control shown in this figure, first, in step S1, energization to the heater unit 63a is started, and heating of the deodorizing filter 62 is started.

  Next, in step S2, it is determined whether or not the temperature detected by the temperature detecting means is higher than the set temperature a described above. If this determination is established, the process proceeds to step S3 to energize the heater unit 63a. To stop. On the other hand, if the determination in step S2 is not satisfied, the determination in step S2 is continued until the determination is satisfied. Next, in step S4, it is determined whether or not a rapid temperature rise has occurred based on the detected temperature. If this determination is established, the process proceeds to step S16 to notify an error. On the other hand, if the determination in step S4 is not established, the process proceeds to step S5, and energization to the heater unit 63a is started.

  Next, in step S6, it is determined whether or not the temperature detected by the temperature detecting means is higher than the set temperature b described above. If this determination is established, the process proceeds to step S7 to energize the heater unit 63a. To stop. On the other hand, if the determination in step S6 is not satisfied, the determination in step S6 is continued until the determination is satisfied. Next, in step S8, it is determined whether or not a rapid temperature rise has occurred based on the detected temperature. If this determination is satisfied, the process proceeds to step S16 to notify an error. On the other hand, if the determination in step S8 is not established, the process proceeds to step S9, and energization to the heater unit 63a is started.

  Next, in step S10, it is determined whether or not the temperature detected by the temperature detection means has reached a specified temperature α. If this determination is not satisfied, the determination in step S10 is continued until the determination is satisfied. When the determination in step S10 is established, the process proceeds to step S11, the energization to the heater unit 63a is stopped, and it is determined whether or not a rapid temperature increase has occurred in step S12. When the determination in step S12 is established, the process proceeds to step S16 to notify an error. If the determination in step S12 is not established, the process proceeds to step S13.

  Next, in step S13, it is determined whether or not the temperature detected by the temperature detecting means is equal to or lower than the specified temperature α. If this determination is established, the process proceeds to step S14 and energization of the heater unit 63a is started. To do. If the determination in step S13 is not established, the determination is continued until the determination is established. Next, in step S15, for example, it is determined whether or not the specified time t has elapsed since the energization of the heater unit 63a was started in step S1. When this determination is established, it is determined that sufficient heat treatment has been performed on the portion of the deodorizing filter 62 that faces the heater unit 63a, the heater unit 63a is stopped, and the heating control is terminated. On the other hand, if the determination in step S15 is not established, the process returns to step S10, and the processes in steps S10 to S15 are repeated.

  By performing the above processing, the temperature characteristics shown in FIG. 11 can be obtained. In step S15, the case where the starting point of the specified time t is the start of energization of the heater unit 63a (step S1) is illustrated. However, the present invention is not limited to this, and the starting point of the specified time t may be the time when the temperature detected by the temperature detecting means reaches the specified temperature α (the time when the determination in step S10 is established).

  Moreover, in the heating control shown in FIG.11 and FIG.12, the process which interrupts heating twice with preset temperature a and b until it reaches | attains specified temperature (alpha) was illustrated. However, the present invention is not limited to this, and the temperature and frequency at which heating is interrupted may be set to an arbitrary value according to the usage environment of the air conditioner 1, the physical property value of the odor component to be processed, and the like. . Moreover, it is preferable to increase the frequency | count of interrupting heating, so that the specific temperature (alpha) is high.

  As a specific example, when the air conditioner 1 is used in an environment where acetaldehyde is high and the specified temperature α is equal to or higher than the minimum temperature α ′ in the temperature range suitable for removing acetaldehyde, the minimum temperature is set as the set temperature for interrupting heating. Three temperature values that are 50 to 60%, 75 to 85%, and 90 to 98% of the temperature are set. In the heating control, heating of the deodorizing filter 62 may be performed in three stages while the heating is interrupted at these temperature values and a sudden temperature rise is detected.

  When the specified temperature α is lower than the minimum temperature α ′, two temperature values that are 35 to 45% and 50 to 60% of the minimum temperature are set as the set temperatures for interrupting heating. In the heating control, heating of the deodorizing filter 62 may be performed in two stages while heating is interrupted at these temperature values. In addition, the specific value of the set temperature mentioned above is an example, and the specific ratio of the set temperature to the minimum temperature α ′ is the magnitude relationship between the specified temperature α and the minimum temperature α ′ and the physical property value of the odor component to be processed. What is necessary is just to set to arbitrary values according to etc.

  Further, during the execution of the filter regeneration operation described above, it is preferable to stop the blower fan 44, particularly after the temperature of the deodorizing filter 62 reaches the specified temperature α. Thereby, the temperature of the deodorizing filter 62 can be raised efficiently, and the state which reached | attained regulation temperature (alpha) can be hold | maintained stably.

From the above, according to the present embodiment, the following effects can be obtained. First, the deodorizing filter 62 includes an inorganic adsorbent that does not cause combustion and ignition due to heating by using zeolite, silica or the like as a main component, and an MnO ₂ catalyst having at least an OMS-2 type crystal structure, It is provided with a honeycomb core that is a base material that is free from the risk of combustion and ignition by using stainless steel, aluminum, ceramic, or the like as a raw material. The inorganic adsorbent and the MnO ₂ catalyst are applied or impregnated into the honeycomb core. Thereby, the deodorizing filter 62 has a high heat resistance and is configured to be regenerated by heating.

Most metal oxide catalysts including MnO ₂ catalyst exhibit a catalytic function of converting ethanol, acetaldehyde, etc. to CO ₂ in a high temperature region of 140 ° C. or higher. On the other hand, the MnO ₂ catalyst having the OMS-2 structure can convert CO ₂ from a low temperature region around 90 ° C. For example, in a one-pass flow system in which ethanol is passed to the catalyst, when the catalyst is heated to 100 ° C., the CO ₂ conversion of a general MnO ₂ catalyst is 0%, whereas the MnO ₂ catalyst having an OMS-2 structure is used. It has been confirmed that the CO ₂ conversion is 3%. Further, it has been confirmed that the amorphous OMS-2 has a CO ₂ conversion rate of 10% depending on the concentration.

That is, according to the present embodiment, by using the deodorization filter 62 supporting the MnO ₂ catalyst having the OMS-2 structure, the odor component is efficiently removed even in a low temperature state of 100 ° C. or less, and the deodorization filter 62 is heated. In addition, the reproduction process can be performed stably. At this time, since parts other than the catalyst of the deodorizing filter 62 are formed of a material having high heat resistance, it is possible to reliably suppress the occurrence of combustion and ignition during the filter regeneration operation regardless of the heating temperature. And high reliability can be realized.

In this Embodiment 1, since it aims at the reproduction | regeneration processing of the deodorizing filter 62 by which the odor component was adsorbed, if it has a function which can be decomposed | disassembled even if it is 1%, for example, it will adjust CO2 by adjusting heating time. It is possible to perform decomposition up to ₂ . In the decomposition process, ethanol generates intermediate organisms such as acetic acid and acetaldehyde as odor components. In particular, since acetaldehyde is contained in various daily odors such as cooking odor and tobacco odor, in a deodorizing device for the purpose of removing daily odors, by using a MnO ₂ catalyst having an OMS-2 structure. The reproduction effect can be sufficiently obtained.

Whether or not the MnO ₂ catalyst has an OMS-2 structure can be specified by X-ray analysis. FIG. 13 is a characteristic diagram showing a waveform pattern when a MnO ₂ catalyst having an OMS-2 structure is measured by XRD. As shown in this figure, it is a feature of the MnO ₂ catalyst having the OMS-2 structure that has peaks appearing in the vicinity of 5,15,29,37 (2 theta / degree). Therefore, based on the waveform pattern shown in FIG. 13, it can be determined whether or not the MnO ₂ catalyst having the OMS-2 structure is included.

  In addition, since the deodorizing filter 62 is configured to be regenerated by heating, it is desirable that there is no fear of ignition and combustion due to heating. Since the use environment of the first embodiment is various and there is a possibility of sucking in things that may accumulate heat and self-ignite, the spread of combustion from the heating location and the risk of fire etc. are as much as possible This is because it needs to be reduced. In particular, since the deodorizing filter 62 is often heated inside the air conditioner 1 as in the present embodiment, a part or non-combustible material that has been subjected to flame retardant treatment is disposed around the deodorizing filter 62. It is desirable to use parts using

  Next, the advantage that the regeneration temperature of the deodorizing filter 62 is 100 ° C. or less will be described. If the deodorizing filter 62 is at a low temperature of 100 ° C. or lower, it is not necessary to use metal for the holding parts that hold the deodorizing filter 62 and the heater unit 63a. For example, in addition to the above-mentioned high density PE, PP, PC, resin materials such as ABS, PS, PET, POM (acrylonitrile / butadiene / styrene copolymer synthetic resin, polystyrene, polyethylene terephthalate, polyacetal) are about 100 ° C. The holding component can be formed using these resin materials. In the present embodiment, the holding components include a unit case 63b that holds the heater unit 63a, a partition plate 65 (a guide portion 65e, a filter holding surface 65k, a filter holding portion 65f) that holds the deodorizing filter 62, and the like. is there.

  Furthermore, when the regeneration temperature of the deodorizing filter 62 is 80 ° C. or less, the holding component is formed using all the resin materials except a part of, for example, PVC, PVAL (polyvinyl chloride, polyvinyl alcohol) and the like. Therefore, a metal material for holding the deodorizing filter 62 is not required. Thereby, size reduction and weight reduction of the air conditioner 1 can be promoted, and components of the air conditioner 1 can be easily formed by resin molding or the like.

  In addition, it is possible to replace the HEPA filter 12 mounted in the first embodiment with a coarser filter having a low pressure loss. When heating at 100 ° C. or higher, there was a risk of combustion due to heat generation even with small dust due to the high temperature. However, if the temperature is lowered to 100 ° C. or lower, particularly 80 ° C. or lower, there is no risk of combustion, and even if dust adheres, it is not necessary to consider the risk of ignition.

  Further, when the regeneration temperature of the deodorizing filter 62 is 100 ° C., in the actual filter regeneration operation, the specified temperature α is set to 100 ° C., and the heater unit 63a needs to be heated to the specified temperature α or higher. For example, since the deodorizing filter 62 has a constant thickness in the axial direction, the surface of the deodorizing filter 62 is specified so that the internal temperature of the deodorizing filter 62 becomes the specified temperature α in the filter regeneration operation. Heat to temperature α or higher. Thereby, heat can penetrate into the inside of the deodorizing filter 62 and the inside can be maintained at the specified temperature α. In particular, when ceramic or the like is used as a base material of the deodorizing filter 62, it is preferable that the heating temperature by the heater unit 63a is set high because the surface heat is difficult to be transmitted to the inside.

The adsorbent used for the deodorizing filter 62 is, for example, zeolite in which silica and alumina are mixed at an appropriate ratio. It is desirable that this zeolite is mixed with more silica than alumina and has a hydrophobic property. A MnO ₂ catalyst having an OMS-2 structure tends to deteriorate in performance in a state where a large amount of moisture is retained. As a specific example, when air having a relative humidity of about 50% is circulated through a MnO ₂ catalyst having an OMS-2 structure, the CO ₂ conversion rate may be halved compared to when air in a dry state is circulated. . Therefore, it is preferable that the deodorizing filter 62 does not contain moisture, and the adsorbent is preferably hydrophobic. Furthermore, it is desirable that the pore diameter is 5 mm or more as the center diameter. This is because it is necessary to support from the target gas component to a gas component having a benzene ring, and there must be a substance having a larger pore size than benzene or the like.

  Next, the effect of the air conditioner 1 provided with the deodorizing filter 62 will be described. The air conditioner 1 includes a heating unit 63 that heats the deodorizing filter 62 to a high temperature of 80 ° C. or higher, and a blower fan 44 that causes air to flow through the deodorizing filter 62. Heating at 80 ° C. or higher is a minimum temperature condition necessary for regenerating the deodorizing filter 62. Below this temperature, it becomes difficult to regenerate the deodorizing filter 62. The blower fan 44 has a function of efficiently bringing odor components in the air into contact with the deodorizing filter 62, and releases the odor that cannot be felt by human odor from the deodorizing filter 62, thereby extending the deodorizing filter 62. It also has an effect.

  The blower fan 44 may be configured to continue to operate during the filter regeneration operation (when the heating unit 63 is activated). During the filter regeneration operation, part of the odor component desorbed from the deodorizing filter 62 by heating may be adsorbed by the deodorizing filter 62 again. On the other hand, if the blower fan 44 is operating, the deodorized odor component can be moved to a position away from the deodorization filter 62 by the wind of the blower fan 44, and the regeneration of the deodorization filter 62 by heating is efficiently performed. It can be carried out.

  Moreover, in this Embodiment, it is set as the structure which can heat the fan-shaped heating object site | part which is a part of the deodorizing filter 62 formed circularly by the heating unit 63, and the deodorizing filter 62 is rotated by the drive mechanism 64. By changing the part to be heated, the entire deodorizing filter 62 is heated. As a result, the entire deodorizing filter 62 can be divided into a plurality of parts, and the heating unit 63 can heat each part separately. Therefore, it is possible to suppress the amount of the odor component that is desorbed from the deodorizing filter 62 by one heating, and to maintain a good surrounding environment during the filter regeneration operation. In addition, since the heating unit 63 only needs to be able to heat only a part of the deodorizing filter 62 by one heating, the heating unit 63 can be downsized as compared with the size of the deodorizing filter 62.

  In the present embodiment, a gas sensor may be arranged near the suction port 11. The deodorizing filter 62 has a regeneration function for daily odors, particularly odor components such as aldehydes and alcohols. However, the deodorization filter 62 is used for linear polymer gas components such as decane and dodecane generated by burning kerosene. On the other hand, the playback function tends to be low. For this reason, in a low-temperature area using a gas fan heater or the like, it is necessary to separately install a replaceable exclusive removal filter in front of the deodorizing filter 62. Therefore, if the gas sensor for detecting such a linear polymer gas component is provided, the blower fan 44 can be stopped when the gas sensor detects the polymer gas component. Thereby, it is possible to prevent the regeneration function of the deodorizing filter 62 from deteriorating without using a dedicated filter or the like. Therefore, the size and weight reduction of the air conditioner 1 can be further promoted.

  In the present embodiment, a dust sensor that detects dust may be disposed in the vicinity of the suction port 11. As a result, since the air volume of the blower fan 44 can be reduced or the blower fan 44 can be stopped according to the detected amount of dust, the influence when the configuration in which the HEPA filter 12 is omitted is further reduced. it can. Therefore, the size and weight reduction of the air conditioner 1 can be further promoted.

  From the above, according to the present embodiment, it is possible to realize the deodorizing filter 62 that has a function of decomposing odor gas even at a low temperature and can be regenerated in a low temperature range even if there is temperature unevenness. A small and lightweight air conditioner 1 equipped with such a deodorizing filter 62 can be provided.

  The first embodiment is merely an example of the configuration according to the present invention, and the present invention is not limited to this configuration. That is, the present invention only needs to include a deodorizing filter that regenerates at a low temperature of 100 ° C. or less, a blower, and a heating regeneration mechanism. Specifically, the air purifying equipment of the present invention includes, for example, ceiling installation equipment such as a range hood fan, cooking equipment such as an IH cooking heater, air conditioning equipment such as an air conditioner, and blower equipment such as a fan. Moreover, the deodorizing filter of this invention is not limited to the deodorizing filter 62, The various filters mounted in said each apparatus are included.
