  However, in the conventional configuration, the intake air flow generated in the vicinity of the air inlet 32 by the blower 30 is weak, it becomes difficult to directly suck the odor of the generation source, and the odor is diffused and diffused at 360 degrees. The odor will be sucked and deodorized. In other words, in order to reduce the uniformly diffused odor concentration, it is necessary to deodorize over a long period of time, and during that time, the high concentration of odor is surely diffused into the space, and the human olfactory organ, the nose. There was a risk of reaching.

  Further, if the suction air volume is increased in order to increase the odor suction amount, a large amount of foreign matter such as dust is sucked together with the odor. When the sucked dust or the like adheres to the deodorizing element, not only the deodorizing power of the deodorizing element is deteriorated but also a problem of a decrease in the air volume due to an increase in the intake resistance occurs, and the deodorizing effect as the deodorizing device is reduced. It is obvious from the fact that foreign matter such as dust is generally accumulated on the floor surface, this is more remarkable as the intake port is closer to the floor surface.

  This invention solves the subject of the said prior art, and is providing the deodorizing apparatus with a high deodorizing effect by attracting | sucking an odor quickly.

  In order to achieve the above object, the present invention provides a main body case having an air inlet at the lower part and an air outlet at the upper part, and a main body case, respectively. A deodorizing element that removes odors contained therein, a blower that sucks air from the intake port, blows out the air from the outlet, and returns to the deodorizing element, and a control unit that controls the blower and the like. The deodorizing apparatus is configured so that a downward intake flow is generated and sucked before diffusion, and a prefilter for preventing clogging of dust and the like in the deodorizing element is provided detachably.

  By the above means, the odor from the odor source can be sucked by the intake air flow downward from the intake port and deodorized before diffusion, and the odor is sucked from the lower part of the main body to the nose where the odor is human olfaction. It can be sucked in such a way that it does not reach it, and it can be deodorized with almost no odor. Here, due to the action of the pre-filter, there is no adhesion of dust etc. to the deodorizing element, it is possible to keep the deodorizing power of the deodorizing element, and it is possible to remove dust etc. by making a removable pre-filter, and the intake resistance Decrease in air volume due to an increase in the amount can be prevented, and the deodorizing efficiency of the deodorizing apparatus can be maintained. Further, the prefilter can ensure safety because the deodorizing device cannot be operated when the storage cover is open.

  As described above, according to the present invention, it is possible to suck and deodorize before odor is diffused, so that a deodorizing apparatus capable of performing quick and efficient deodorization is obtained.

  The first invention provides a main body case provided with an air inlet at the lower part and an air outlet at the upper part, respectively, and an odor contained in the air by allowing air from the inlet to pass through. A deodorizing element using a honeycomb-like adsorbing element to remove air, a blower that sucks air from the intake port, blows out from the blowout port and returns to the deodorizing element, and a control unit that controls the blower and the like. It is constructed so that a downward intake air flow is generated and sucked before the odor inside diffuses upward, and a prefilter that prevents clogging of dust etc. into the deodorizing element, and the prefilter is detachably stored, and A storage cover that can be opened and closed on the intake side is provided so that the prefilter is not attached to the storage cover or cannot be operated when the storage cover is open. The decrease in the amount, by secure attachment of the pre-filter is prevented by preventing the clogging of dust, etc. into the deodorizing device, it is possible to prevent secular decrease in deodorizing effect.

  The second invention is configured to detect a change in the rotational speed of the blower or a change in the power input amount of the blower, determine adhesion of dust or the like to the prefilter, and notify the cleaning or replacement timing of the prefilter. Yes, by detecting a decrease in the intake air amount in the deodorization device, a change in the rotation speed of the blower or a change in the power input amount of the blower can be avoided to reduce the deodorization effect during use, and the prefilter should be periodically cleaned and replaced By doing so, the deterioration of the deodorizing effect over time can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
1 is a schematic sectional side view of a deodorizing apparatus according to a first embodiment of the present invention, and FIG. 2 is a schematic front view in which a main part of the deodorizing apparatus is cut away.

  The main body case 1 is provided with an air inlet 2 at the lower front portion of the main body case 1 and an air outlet 3 at the upper portion of the main body case 1 extending from the front upper end to the upper surface. The main body case 1 has a honeycomb-like deodorizing element 4 that removes odors contained in the air by passing air sucked from the air inlet 2, and air is sucked from the air inlet 2 as a downward intake air flow. 3 and a control unit 6 for controlling the blower and the like, and the intake port 2 and the blower 5 have a downward intake flow before the generated odor is diffused upward. It is configured to generate and suck.

  The deodorizing element 4 is composed of a quadrilateral honeycomb body of an adsorbing element in which the thickness in the air aeration direction is removed to remove odor contained in the air by passing air through a large number of honeycomb-shaped cells, and the upper end portion is formed. The bottom end of the upper surface of the main body case 1 is positioned at the lower end of the lower surface of the front surface of the main body case 1 and the upper case 2 occupies approximately 2/3 of the main body case 1 at an oblique angle. doing. Therefore, the deodorizing element 4 faces the air outlet 3 on the upper side of the main body case 1 provided from the upper end of the front surface of the main body case 1 to the upper surface diagonally upward and on the downstream side.

  In order to reduce the pressure loss of the air passage, the deodorizing element 4 sets a value obtained by dividing the ventilation area of the honeycomb body by the thickness in the ventilation direction of the honeycomb body to 3000 or more, and honeycomb cells per inch square The number is 250 or less.

  The blower 5 is constituted by a cross flow fan having a motor 7 and is provided on the upstream side of the deodorizing element 4. That is, the blower 5 is opposed to the full width of the intake port 2 and is located directly below the deodorizing element 4 so as to be fully under the intake port 2. The intake side is connected to the intake port 2 and the exhaust side is connected to the deodorizing element 4 side, and the tongue portion 9 for controlling the intake flow is sucked in from the intake port 2 obliquely downward with respect to the horizontal so that the downward intake flow is generated. Arranged to occur.

  The pre-filter 10 is provided at the intake port 2 to prevent clogging of dust in the deodorizing element 4, and a storage cover 11 that is pivotally supported at the lower end of the main body case 1 and attached to the intake port 2 so that it can be opened and closed to the front side. It is stored in a removable manner. Therefore, when removing the attached dust, as shown by the dotted line, the storage cover 11 is opened on the front side of the main body case 1 and the prefilter 10 is taken out, and the regenerated prefilter 10 is stored in the storage cover 11 again. Thus, the storage cover 11 is closed.

  Reference numeral 12 denotes a filter attachment detection means such as a microswitch that electrically contacts the prefilter 10 received in the storage cover 11 closed to the intake port 2 and electrically sends a signal to the control unit 6. It is provided in the main body case 1. Therefore, the control unit 6 is configured so that the blower 5 cannot be operated when the storage cover 11 is closed with the prefilter 10 not attached or when the storage cover 11 is opened even when the prefilter 10 is attached. .

  Further, the control unit 6 detects the degree of dust adhesion to the pre-filter 10 based on a change in the rotational speed of the blower 5 or a change in the power input amount of the blower, and compares and determines the detected value. When the value of the power input amount change exceeds the set value, the cleaning or replacement time of the pre-filter 10 is notified. It should be noted that the rotational speed change of the blower 5 is detected by a hall element provided in the motor 7, and the power input amount change of the blower 5 is configured to detect the value of the current flowing to the motor 7 due to the work amount of the blower 5. Yes.

  Reference numeral 13 denotes an entire operation unit of the deodorizing apparatus connected to the control unit 6, which faces the front surface of the main body case 1, and is partially operated when the prefilter 10 is not attached to the storage cover 11 or the storage cover 11 is opened. Display when the control unit 6 is controlling so that it cannot be performed, and display when the control unit 6 determines the cleaning or replacement timing of the prefilter 10 by determining the degree of dust adhesion to the prefilter 10 Etc. are provided. In addition, the arrow in a figure shows the flow of the air at the time of deodorizing.

  Next, operation | movement of the deodorizing apparatus comprised as mentioned above is demonstrated. When an operation signal is input from the operation unit 13, an operation signal is sent from the control unit 6 to the motor 7 based on a sequence set in advance according to the input. At this time, the control unit 6 determines that the pre-filter 10 is normally attached based on the detection signal of the filter attachment detection means 12, and if it is not attached, the operation is stopped. Going inside.

  The blower 5 rotated by the operation of the motor 7 sucks the generated odor in the air through the pre-filter 10 from the lower air inlet 2 of the main body case 1. That is, the arrangement of the casing 8 and the tongue 9 of the blower 5 with respect to the air intake 2 causes an obliquely downward intake flow to be generated in the air intake 2 at the lower part of the main body case 1, before the odor is diffused, and the human olfaction Before the odor reaches the nose, the body case 1 can be inhaled.

  The inhaled odor passes through the air passage in the main body case 1 and passes through the deodorizing element 4 disposed obliquely to be deodorized. At this time, the deodorizing element 4 is composed of a honeycomb-shaped adsorbing element and is thin in the direction of air flow, so that there is little pressure loss in the air passage, and the fan 5 of the crossflow fan reduces noise and generates a large amount of air. Inhalation is possible.

  In addition, since the deodorizing element 4 is provided in the main body case 1 obliquely upward just above the blower 5, it can be arranged in a thin and space-saving manner. As a result, the main body case 1 can be made compact, and the air outlet 3 is provided. Since it can be provided at a high position above the main body case 1, it is possible to provide a deodorizing device in which a short circuit with the intake port 2 below the main body case 1 hardly occurs.

  Further, since the cross flow fan can secure a long air path on the downstream side, a large air volume can be stably generated without impairing the performance of the blower 5.

  Further, the blower 5 constituted by a cross flow fan can be provided at the upstream side of the deodorizing element 4 to increase the flow speed on the intake side, and the odor in the air can be surely received at the intake port 2 below the main body case 1. Can inhale. Moreover, since the change in the air path on the downstream side of the blower 5 can be reduced, a deodorizing device with low air flow pressure loss and low blowing noise can be obtained.

  Moreover, since the blower outlet 3 is arrange | positioned in the upper surface which is the upper part of the main body case 1, the air which passed the deodorizing element 1 goes to the ceiling of the room which has installed the apparatus from the blower outlet 3 of the upper part of the main body case 1. It is discharged and convects downward from the ceiling through the wall surface, which promotes the diffusion of residual odor and promotes the reduction of the odor level in the indoor space.

  Moreover, when dust adheres to the pre-filter 10 in the deodorizing device, the amount of blown air is reduced and the deodorizing ability is reduced. When dust adheres to the prefilter 10 of the deodorizing device to suppress this to the minimum and the air flow rate decreases, the control unit 6 detects a change in the rotational speed of the blower 5 or a change in the power input amount of the air blower, and the prefilter 10 The cleaning or replacement time is displayed on the notification unit 14. Thereby, it can be set as the deodorizing apparatus with which the deodorizing capability was stabilized.

  As described above, according to the present invention, the following operational effects can be obtained.

  According to the present invention, the main body case includes a deodorizing element that removes odors contained in the air by allowing air to pass through, and a blower that recirculates air to the deodorizing element, and the intake port is provided on the bottom surface of the main body case or the lower front portion. The air outlet is provided on the upper surface of the main body case or the upper part of the front surface and sucked with the downward intake flow before the odor diffuses upward, so that a strong downward intake flow is generated at the lower portion of the main body case. The odor can be sucked and deodorized before diffusion. Therefore, it is possible to perform deodorization quickly and efficiently, and by generating an intake air flow downward, it is possible to inhale before the odor reaches the human nose, and deodorization can be performed with almost no odor. .

  Further, according to the present invention, the intake port is provided on the lower front surface of the main body case, and the intake port and the air blower that make the intake air flow from the intake port an obliquely downward intake flow are provided. By having a downward velocity vector due to the duct configuration of the blower, the odor of the generation source can be effectively sucked by the suction flow of the blower, and a main body structure that can suck the odor before diffusion can be obtained.

  Further, according to the present invention, by providing the blower on the upstream side of the deodorizing element, even if the blower is provided on the upstream side of the deodorizing element having a relatively large area, the intake port of the blower can be configured to be small, A strong and fast flow at the intake can be generated. Thereby, the odor of the generation source can be strongly sucked. Also, on the downstream side of the blower, the flow velocity decreases according to the area of the deodorizing element, but widening the air passage until exhausting at the air outlet reduces the change in flow velocity to the air outlet, reducing pressure loss and increasing the air volume. A low-noise deodorizing device can be obtained.

  In addition, according to the present invention, since the deodorizing element uses a honeycomb-shaped adsorption element, the pressure loss in the air passage can be reduced, so that the deodorizing speed is improved by increasing the air volume, and the air volume is increased and the noise is reduced to a compact size. The structure of the deodorizing apparatus with a blower is attained.

  Further, according to the present invention, the deodorizing element is a honeycomb body having a thin air ventilation direction, and the value obtained by dividing the ventilation area of the honeycomb body by the ventilation thickness of the honeycomb body is set to 3000 or more. Since the air flow direction of the honeycomb body can be reduced and the pressure loss in the air passage can be reduced, the deodorizing speed can be improved by increasing the air volume, and the deodorizing apparatus can be configured with a compact air blower with a larger air volume and lower noise.

  Further, according to the present invention, since the number of cells per inch square is 250 or less in the honeycomb-shaped deodorizing element, the pressure loss of the air passage can be reduced, so that the deodorizing speed is improved by increasing the air volume, and the larger air volume is increased. Therefore, it is possible to construct a deodorizing apparatus with a low-noise and compact blower.

  Moreover, according to this invention, since the air blower was comprised with the cross flow fan, it can be set as a compact deodorizing apparatus with a large air volume and low noise.

  Further, according to the present invention, the deodorizing element is disposed at an angle with respect to the direction of wind flow in the main body case, so that the deodorizing apparatus can be moved even when a deodorizing element having a larger area is used. And a deodorizing device that ensures a large air volume and deodorizing efficiency with a large deodorizing element.

  Further, according to the present invention, the deodorizing device includes a prefilter for preventing clogging of dust on the deodorizing element and a storage cover that can store the prefilter and can be easily attached and detached, and the prefilter is not mounted. Or, since the storage cover cannot be operated when the storage cover is in the open state, it is possible to prevent a decrease in the intake air amount in the deodorizing device by preventing the clogging of the deodorizing element by securely attaching the prefilter, and the deodorizing effect over time. The deodorizing device can be configured to prevent a general decrease.

  Further, according to the present invention, a configuration for detecting a change in the rotational speed of the blower or a change in the power input amount of the blower, determining adhesion of dust to the prefilter of the deodorizing device, and displaying a cleaning or replacement time of the prefilter Therefore, it is possible to avoid a decrease in the deodorizing effect during use by detecting a decrease in the intake air amount in the deodorization device, a change in the rotation speed of the blower or a change in the power input amount of the blower, and periodically cleaning and replacing the prefilter By performing the above, it is possible to obtain a configuration of a deodorizing apparatus that can prevent aged deterioration of the deodorizing effect.

  As described above, the deodorization apparatus according to the present invention can suck and deodorize before odor is diffused, and can perform quick and efficient deodorization.
