Description

  The present invention relates to a deodorizing apparatus.

  As a deodorizing apparatus, an apparatus that simultaneously heats the entire surface of the deodorizing means with a heating means has been proposed. According to this deodorizing apparatus, the deodorizing performance of the entire deodorizing means can be recovered at the same time (see, for example, Patent Document 1).

  However, in the deodorizing apparatus described in Patent Document 1 and the like, the larger the deodorizing means, the larger the heating means. For this reason, in order to recover the deodorizing performance of a large deodorizing means, a large amount of electric power is consumed.

  1 to 3, reference numeral 1 denotes a main body case. The main body case 1 is formed of a substantially rectangular parallelepiped resin or the like. As shown in FIGS. 1 and 3, a suction port 1 a is provided in substantially the entire area of one side surface of the main body case 1. The suction inlet 1a is provided along with the vertical direction in a state where the longitudinal direction is the horizontal direction. The suction port 1 a opens in the horizontal direction toward the outside of the main body case 1. As shown in FIGS. 1-3, the blower outlet 1b is formed in the upper surface of the other side of the main body case 1. As shown in FIG. The blower outlet 1b is provided so that a longitudinal direction may match the longitudinal direction of the suction inlet 1a. The blower outlet 1b opens in the vertical direction toward the outside of the main body case 1. As shown in FIG. 3, an air blowing means 2 is provided near the inside of the other surface of the main body case 1. A ventilation path R is formed in the main body case 1. The ventilation path R reaches the blower outlet 1b through the blower means 2 from the inlet 1a. However, the inlet 1a and the outlet 1b may be configured so as to allow air to flow, and are not limited to the shape and arrangement described above for design reasons.

  As shown in FIGS. 2 and 3, the deodorizing means 3 is provided over substantially the entire area inside one surface of the main body case 1. Driving means (not shown) such as a motor is attached to the deodorizing means 3. On the downstream side of the lower part of the deodorizing means 3, a heating means 4 is provided. A minute heating space 5 is formed between the deodorizing means 3 and the heating means 4. A control means (control board) 6 is provided near the inside of the upper surface of the main body case 1.

Next, the deodorizing means 3 and the heating means 4 will be described with reference to FIG.
FIG. 4 is a perspective view of a main part of the deodorizing apparatus according to Embodiment 1 of the present invention.

  As shown in FIG. 4, the deodorizing means 3 is formed in a circular shape. Depending on the deodorizing performance required for the deodorizing device and the size of the deodorizing device, a plurality of deodorizing means 3 may be arranged in the direction of the flow of the wind in the ventilation path R. The deodorizing means 3 is divided into a plurality of deodorizing areas 3a. In addition, the deodorizing area | region 3a may be attached to the deodorizing means 3 so that attachment or detachment is possible. In FIG. 4, the deodorizing means 3 is arrange | positioned so that eight fan-shaped deodorizing area | regions 3a may be located in a plane, for example. The deodorizing area 3a is formed so that air passes through it. For example, the deodorizing region 3a is formed of a honeycomb, fin, mesh, or plate metal. A catalyst is attached to the deodorizing region 3a. Note that a material other than a metal having good thermal conductivity may be used as the deodorizing region 3. The thermal conductivity is preferably 10 W / (m · k) or more.

  Between the adjacent deodorizing areas 3a, a heat insulating area 3b is arranged. Moreover, as shown in FIG. 4, the heat insulation area | region 3b is made into the structure which partitions off between the deodorizing area | regions 3a in the state adjacent to the depth direction with the same material. The heat insulation area | region 3b has heat conductivity lower than the heat conductivity of the deodorizing area | region 3a. For example, the heat insulating region 3b is formed of ceramic. The heat insulating region 3b may be formed of glass wool, rock wool, wool heat insulating material, cellulose fiber, or carbonized cork mainly used for construction or the like. The heat insulating region 3 b may be formed of a foam heat insulating material that can withstand the temperature rise of the heating means 4. The heat insulating region 3b may be formed of an air layer or a vacuum layer. When the heat insulating region 3b is formed of an air layer or a vacuum layer, a support column for fixing the deodorizing region 3a is provided.

  As shown in FIG. 4, the heating means 4 is formed in a fan shape. The central angle of the heating means 4 is wider than the central angle of each deodorizing region 3a. A heat insulating material (not shown) is provided other than the surface of the heating unit 4 facing the deodorizing unit 3. The area of the heating means 4 and the amount of heat to be applied are individually set based on the amount of heat that decreases before reaching the deodorizing means 3.

Next, operation | movement of a deodorizing apparatus is demonstrated using FIG.
FIG. 5 is a diagram showing an arrangement relationship of the heating means, the heat insulating portion, and the deodorizing means of the deodorizing apparatus in Embodiment 1 of the present invention.

  When a switch (not shown) or the like provided in the main body case 1 is operated, the control means 6 operates the air blowing means 2. By this operation, indoor air is introduced into the main body case 1 from the suction port 1a. The air is blown out from the outlet 1b via the ventilation path R. At this time, the odorous substance in the air is adsorbed by the deodorizing means 3. Due to the adsorption, the deodorizing performance of each deodorizing region 3a is lowered.

  Thereafter, the deodorizing performance recovery operation of the deodorizing region 3a is performed at a predetermined timing. The predetermined timing is, for example, after the daily deodorizing operation is finished. In this case, it carries out about only one deodorizing area 3a. Thereby, the power consumption per day by the heating means 4 can be suppressed. In addition, when giving priority to the regenerating operation, the heating operation to the deodorizing region 3a can be continuously performed on the plurality of deodorizing regions 3a. Further, as another example of the predetermined timing, when the accumulated time from the start of operation exceeds a predetermined time, or the accumulated time from the performance recovery operation of the deodorizing performance of the deodorizing means 3 performed last time exceeds the predetermined time. It may be a case. Further, the deodorizing performance recovery operation may be performed in parallel with the operation of the air blowing means 2.

  As the deodorizing performance recovery operation of the deodorizing area 3a, the control means 6 controls the relative position of the heating means 4 and the deodorizing area 3a. Specifically, as shown in FIG. 2, the control means 6 rotates the deodorizing means 3 through the driving means so that the heating means 4 faces one whole surface of the deodorizing region 3a. For example, as shown in FIG. 5, the control unit 6 rotates the deodorizing unit 3 so that one edge of the heating unit 4 overlaps the heat insulating region 3 b on one side of the deodorizing region 3 a on the vertical projection plane. Moreover, the control means 6 may rotate the deodorizing means 3 so that the heat insulation area | region 3b of the both sides of the said deodorizing means 3 is arrange | positioned inside the both edges of the heating means 4. FIG. As a result, as shown in FIG. 2, the deodorizing area 3 a is arranged to be the heating target area A. In this state, the control means 6 stops the rotation of the deodorizing means 3.

  Thereafter, the control means 6 raises the temperature of the heating means 4 to a temperature required to reach the temperature required for the regeneration of the deodorizing region 3a based on the heating control program. At this time, whether or not the target temperature has been reached may be determined by a detection result of a temperature detection means (not shown), or a temperature increase program (Δ ° C./min× You may determine by the heating time based on min).

  Thereafter, when the deodorizing means 3 raises the temperature to the target temperature, the control means 6 causes the heating means 4 to continue heating for a predetermined time. At this time, the heating temperature and the heating time are set to a temperature and time sufficient to remove the odorous substance adsorbed on the deodorizing means 3.

  At this time, the heat insulating material of the heating unit 4 suppresses heat radiation from the heating unit 4 to other than the heating space 5. For this reason, the heat retention effect of the heating target area A is enhanced. As a result, the amount of electric power consumed to bring the deodorizing means 3 to the target temperature is suppressed.

  The heat of the deodorizing area 3a in the heating target area A tends to be conducted to the deodorizing area 3a in the non-heating target area B. However, the heat insulating regions 3b are arranged on both sides of the heating target region A. For this reason, the conduction of the heat is suppressed in the heat insulating region 3b.

  When the operation by the heating control program is completed, the control means 6 rotates the deodorizing means 3 by a predetermined angle so that one whole surface of the deodorizing area 3a adjacent to the heated deodorizing area 3a faces the heating means 4.

  The above operation is determined based on various conditions such as the adsorption performance of the deodorizing means 3 and the presence or absence of catalyst attachment. For example, before the odor substance adsorption capacity of the deodorizing means 3 is exceeded, the entire deodorizing area 3a is regenerated.

  According to Embodiment 1 demonstrated above, as for the deodorizing means 3, the some deodorizing area | region 3a is divided | segmented by the heat insulation area | region 3b. For this reason, it can suppress that heat | fever conducts from the deodorizing area | region 3a of the heating object area | region A to the deodorizing area | region 3a of the non-heating object area | region B. FIG. As a result, the deodorizing means 3 can be efficiently regenerated. That is, power consumption can be suppressed when the deodorizing region 3a is heated to a temperature at which the odorous substance adsorbed on the deodorizing region 3a is removed.

  At this time, an increase in the temperature of the outlet 1b is also suppressed. That is, even if the deodorizing operation and the regeneration operation of the deodorizing area 3a are performed at the same time, the heating means 4 is insulated or the deodorizing area 3a is insulated by the heat insulating area 3b. The heat conducted to the region A is conducted to the non-heating target region B and dissipated, so that the air blown from the outlet 1b can be prevented from becoming a high temperature. For this reason, user convenience is improved.

  Further, when the heating means 4 faces each deodorizing area 3 a, the entire surface of the deodorizing area 3 a faces the heating means 4. For this reason, the said deodorizing area | region 3a can be reproduced | regenerated in a shorter time.

  Moreover, the deodorizing area | region 3a consists of a metal with high heat conductivity. For this reason, the temperature distribution of the depth direction of the deodorizing area | region 3a of the heating object area | region A can be made uniform rather than the case where the deodorizing area | region 3a is formed with a ceramic etc. with low heat conductivity. In this case, the effect of the heat insulating region 3b becomes remarkable.

  A catalyst is attached to the deodorizing region 3a. The effective temperature at the time of oxidative decomposition of the odorous substance adsorbed on the deodorizing region 3a is different for each type of catalyst. The said temperature is high temperature normally 150 degreeC or more. That is, the difference between the temperature and room temperature is large. However, since the deodorizing region 3a is insulated by the heat insulating region 3b as in the first embodiment, the heat conducted from the heating means 4 does not leak into the non-heating target region B and is in the heating target region A. It is possible to conduct efficiently and intensively with respect to the deodorizing region 3a. Thereby, the odorous substance adsorbed in the deodorizing region 3a is decomposed into water and carbon dioxide by complete oxidation. Owing to the decomposition, the re-release of odorous substances is suppressed. This suppression can suppress user discomfort. Moreover, since the heat applied to the deodorizing area 3a in the heating target area A becomes difficult to be conducted to the deodorizing area 3a in the non-heating target area B due to the presence of the heat insulating area 3b, the deodorizing in the non-heating target area B Occurrence of odor due to a substance that is not oxidized and decomposed by heating the region 3a can be suppressed.

  Moreover, the deodorizing area | region 3a is provided in the deodorizing means 3 so that attachment or detachment is possible. For this reason, if there is no dust removing means upstream of the deodorizing means 3, the deodorizing area 3a can be removed and the dust adhering to the surface of the deodorizing area 3a can be washed with water using a household sink or bucket. As a result, the hygiene of the deodorizing area 3a can be maintained.

  Further, the deodorizing means 3 is formed in a circular shape so that the plurality of fan-shaped deodorizing regions 3a are arranged in a uniform plane without being stepped. In this case, even when the inner surface of the main body case 1 is close to the deodorizing means 3, the deodorizing means 3 can be rotated. For this reason, the outer dimension of a deodorizing apparatus can be made as small as possible. Moreover, the wind by the ventilation means 2 flows uniformly with respect to the whole surface of the deodorizing means 3 in a plane direction. For this reason, odorous substances are also directed to the deodorizing means 3 uniformly. For this reason, the adsorption effective area of the deodorizing means 3 can be utilized effectively.

  The heating unit 4 is provided on the downstream side of the deodorizing unit 3. It is possible to prevent the user from touching the heating means 4 when replacing the dust removing means (not shown) in the deodorizing apparatus from the suction port 1a side.

  The heating means 4 may be provided on the upstream side of the deodorizing means 3 or on both the upstream side and the downstream side. In this case, the temperature of the deodorizing region 3a can be raised in a short time. That is, it is possible to shorten the time that the user waits for the regeneration operation of the deodorizing area 3a.
