Description
Technical Field
The present invention relates to an air treatment device.
Background
With the improvement of living standard, the requirements of people on the office living environment are higher and higher. For example, there is an increasing demand not only for household appliances that regulate the ambient temperature, such as cooling or heating air conditioners, but also for air treatment devices that regulate the ambient humidity, such as humidifiers or dryers.
There is a conventional air treatment apparatus in which a dehumidifying wheel is made of, for example, zeolite, and the dehumidifying wheel can realize a function of adjusting the humidity of air without using a compressor by utilizing the moisture absorption characteristics of the dehumidifying wheel (see, for example, patent document 1 below).
Patent document 1: CN202096871U
Specifically, in the above-described conventional air treatment apparatus, the dehumidification rotor can absorb moisture at normal temperature and can remove moisture at high temperature, and the electric heating device for heating and regenerating the region where the dehumidification rotor absorbs moisture is provided, thereby conveniently realizing a long-term dehumidification function. Zeolite members are generally available in the market as indirect drive for the desiccant wheel through a transmission member, such as a gear set consisting of a driving gear and a driven gear. In this way, not only can the slower rotation speed required by the zeolite member as a desiccant wheel be satisfied, but also the motor can be prevented from being disturbed by a heat source or a cold source by offsetting the motor.
However, the air treatment apparatus of the prior art described above has the following problems: since the gear train as the transmission member is generally molded from a material such as resin having a high thermal expansion coefficient, there is a possibility that a meshing failure occurs between the drive gear and the driven gear of the gear train. In addition, due to the temperature condition of the air treatment device that is constantly changing in cold and heat, the driving gear and the driven gear may be engaged too tightly (the driving gear and the driven gear are too close to each other) or too loosely (the driving gear and the driven gear are too separated or even completely separated) due to thermal expansion and cold contraction, which may cause unstable and discontinuous transmission (for example, in this case, when viewed along the direction of the rotation axis of the driving gear and/or the driven gear, the driving gear and/or the driven gear are in a non-ideal circular shape), and thus the zeolite member cannot be driven to rotate. In addition, the humidity control runner itself is also expanded with heat and contracted with cold, and when the humidity control runner is fitted to the fixed shaft without play, the humidity control runner is locked to the fixed shaft and cannot rotate, and finally the air treatment apparatus is broken down.
Accordingly, there is a need for an improvement in the structure of the prior art air treatment device described above.
Disclosure of Invention
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide an air treatment apparatus capable of preventing a humidity control runner from being locked to a fixed shaft and preventing a driving member and a driven member as a transmission unit from being excessively tightly or loosely engaged with each other, thereby reducing the failure rate of the air treatment apparatus.
In order to solve the above-described technical problem, an air treatment device of the present invention includes: the humidity control device comprises a driving assembly, a humidity control rotating wheel assembly and a supporting body, wherein a driving part in the driving assembly drives a driven part in the humidity control rotating wheel assembly to rotate, the supporting body is provided with a fixed shaft, the driven part is supported by the fixed shaft in a clearance mode, an elastic member is arranged between the supporting body and the driving assembly, and the elastic member can deform under the condition of receiving the force generated by the movement of the driven part, so that the driving part is forced to be matched with the driven part, and the driving part is kept to be matched with the driven part.
According to the above configuration, the driven member is supported by the fixed shaft with play. Thus, the humidity control rotor fixed to the driven member can be prevented from being locked to the fixed shaft and being unable to rotate, as compared with the case where the driven member is fitted to the fixed shaft without play. In addition, the resilient member is capable of deforming when subjected to forces generated by movement of the driven member, thereby forcing the driving member to maintain the driving member in engagement with the driven member. Therefore, the driving part and the driven part which are used as the transmission assembly can be prevented from being matched too tightly or too loosely, and the failure rate of the air treatment device can be reduced.
Preferably, a maximum value of the amount by which the elastic member is deformable is equal to or greater than a value of a play between the driven part and the fixed shaft.
This ensures that the backlash of the driven member is compensated for within the elastic range of the elastic member, thereby further reliably preventing the driving member from being excessively tightly fitted to the driven member.
Preferably, the driving member is a driving gear, the driven member is a driven gear that is engaged with the driving gear and is rotationally driven, and the driving gear and the driven gear are attached to the support body such that rotation axes thereof are parallel to each other.
Here, the "parallel to each other" includes not only a strict parallel relationship but also a case of "substantially parallel to each other". That is, in practical applications, the rotation axis of the driving gear and the rotation axis of the driven gear may not be completely parallel but substantially parallel due to, for example, a wobbling motion during rotation or a process error of the component itself.
According to the above structure, the drive gear as the driving part and the driven gear as the driven part are engaged with each other, and are always kept engaged with each other by the elastic member. Therefore, the driving gear and the driven gear which are used as the transmission assembly can be prevented from being meshed too tightly or too loosely, and the failure rate of the air treatment device can be reduced.
Preferably, the humidity control swivel assembly further includes: a humidity control runner which is provided coaxially with the driven member and has an axial hole at an axial center of the humidity control runner and the driven member; and a sleeve fitted with the axis hole with play, wherein the axis hole on which the sleeve is fitted is engaged with a fixed shaft provided on the support body, thereby pivotally supporting the humidity control wheel assembly on the support body.
According to the above configuration, the sleeve is loosely fitted in the center hole of the humidity control runner and the driven member. This prevents the humidity control runner from becoming unable to rotate due to too tight engagement with the sleeve due to thermal expansion and contraction, and contributes to further reducing the failure rate of the air treatment device.
Preferably, the support body comprises a fan casing to which the drive assembly is mounted.
Therefore, the driving component is arranged on the fan housing, a heat dissipation component and a supporting component for the driving component are not required to be additionally arranged, the original fan component can be directly utilized to dissipate heat of the driving component, the number of parts of the air processing device is further reduced, and the manufacturing cost is reduced while the device is miniaturized.
Preferably, the support body is provided with a first limiting portion, the driving assembly is provided with a second limiting portion, and the first limiting portion and the second limiting portion are elastically matched through the elastic member.
Therefore, the elastic matching of the two limit parts and the elastic component can prevent the driving part and the driven part from being matched too tightly or too loosely by a simple component.
Preferably, one of the first stopper portion and the second stopper portion is a columnar portion, and the other is a hollow clamping portion that is fitted to the columnar portion with the elastic member interposed therebetween.
Thus, the driving member and the driven member can be well fitted to each other with a simple structure in which the elastic member is sandwiched between the two columnar portions and the hollow sandwiching portion.
Preferably, when the outer diameter of the columnar portion is D1 and the inner diameter of the hollow clamping portion is D2, 4 mm. ltoreq.D 2-D1. ltoreq.12 mm.
Thus, by setting the dimensional relationship between the columnar portion and the hollow clamping portion as described above, the driving member and the driven member can be fitted with an appropriate degree of tightness.
Preferably, the first limiting portion is provided with a first protrusion, the second limiting portion is provided with a second protrusion, and the first protrusion and the second protrusion face each other to allow the elastic member to be sleeved with the elastic member.
Thus, by providing two protrusions facing each other, the elastic member can be reliably fitted, and the elastic member is facilitated to be restrained, so that the elastic member and the two protrusions reliably exert an elastic restraining function on the movement of the active component.
Preferably, the elastic member is capable of contracting or expanding in a state where the driving part is engaged with the driven part and rotates, and a minimum length of the elastic member in a compressed state is equal to or greater than a sum of lengths of the first projection and the second projection.
Here, the elastic member capable of contracting or extending in the case where the two gears are rotated in mesh means: when the driving part and the driven part are matched to rotate, the elastic component is always in a state of applying elastic force to the first limiting part and the second limiting part. Thereby, the elastic member can be prevented from falling off from between the first projection and the second projection, as compared with the case where the elastic member is switched between the natural length state and the contracted/extended state. In addition, under the condition that the driving assembly is inclined, when the driven part moves towards the direction far away from the driving part, the driving assembly can enable the elastic component to extend by means of self gravity to enable the driving part to be meshed with the driven part, and therefore the driving part and the driven part are further reliably prevented from being matched too tightly or too loosely.
In addition, according to the above configuration, as compared with a case where the minimum length of the elastic member in the compressed state is smaller than the sum of the lengths of the two protrusions, it is possible to avoid the first protrusion and the second protrusion from coming into contact with each other in the extreme compressed state of the elastic member, and thus it is possible to more reliably prevent the driving member from being excessively tightly fitted to the driven member.
Preferably, one of the first stopper portion and the second stopper portion is provided with a stopper protrusion, the other of the first stopper portion and the second stopper portion is provided with a stopper groove, the stopper groove is formed in a direction parallel to a direction in which the first protrusion and the second protrusion face each other, and the stopper protrusion is engaged with the stopper groove.
Therefore, the limiting protrusions and the limiting grooves which are mutually clamped are arranged in the direction parallel to the opposite direction, so that the two limiting parts can reliably reciprocate in the direction parallel to the opposite direction, the elastic component is prevented from being twisted due to the fact that the driving assembly shakes left and right, and the driving part and the driven part are reliably prevented from being excessively tightly or excessively loosely matched.
Preferably, the air treatment device has a main body part, the main body part has an air inlet, a first air outlet and a second air outlet, and is provided with a fan assembly, the humidity control rotating wheel assembly and a heating assembly, the fan assembly has a fan rotor, an air suction port, a first air supply port and a second air supply port, the axial direction of the humidity control rotating wheel assembly is consistent with the axial direction of the fan rotor of the fan assembly, and the humidity control rotating wheel assembly has a circumferentially adjacent moisture absorption area and a moisture exhaust area, when the fan assembly works, an air flow sucked from the air inlet into the main body part flows through the moisture absorption area and enters the air suction port of the fan assembly, and then the air flow is divided into two paths, one path of the air flow is blown out from the first air supply port of the fan assembly and flows through the moisture exhaust area and is exhausted from the first air outlet, and the other path of the air is blown out from the second air supply outlet of the fan assembly to the second air outlet and is discharged, and the heating assembly is provided with a heating part which heats at least one part of the humidity discharging area.
According to the structure, due to the fact that the driven part in the humidity control rotating wheel component in the air treatment device is in clearance fit with the fixed shaft, the humidity control rotating wheel fixed to the driven part can be prevented from being clamped on the fixed shaft and cannot rotate, further, the heating component is prevented from continuously heating partial areas (humidity discharging areas) of the humidity control rotating wheel in the humidity control rotating wheel component, the risk of fire disasters is reduced, and safety, reliability and stability of the device are improved.
(effect of the invention)
According to the air treatment device of the present invention, the driven member is supported by the fixed shaft with play. This prevents the humidity control runner fixed to the driven member from being locked to the fixed shaft. In addition, the resilient member is capable of deforming when subjected to forces generated by movement of the driven member, thereby forcing the driving member to maintain the driving member in engagement with the driven member. Therefore, the driving part and the driven part which are used as the transmission assembly can be prevented from being matched too tightly or too loosely, and the failure rate of the air treatment device can be reduced.

[ first embodiment ]
First, the air treatment device of the present invention will be described in detail with reference to fig. 1 to 3. As shown in fig. 1, an air treatment device 100 of the present invention includes: the humidity control device comprises a driving assembly 1, a humidity control rotating wheel assembly 2 and a supporting body 3, wherein a driving part in the driving assembly 1 drives a driven part in the humidity control rotating wheel assembly 2 to rotate, the supporting body 3 is provided with fixed shafts 31a and 32a, the driven part is supported by the fixed shafts 31a and 32a in a clearance mode, an elastic member E, E '(refer to fig. 2 and 4) is arranged between the supporting body 3 and the driving assembly 1, and the elastic member E, E' can deform under the condition of receiving the force generated by the movement of the driven part, so that the driving part is forced to be matched with the driven part, and the driving part and the driven part are kept to be matched with each other.
According to the air treatment apparatus 100 of the present invention, the driven member is supported by the fixed shafts 31a, 32a with play. Accordingly, as compared with the case where the driven member is fitted to the fixed shaft without play, the humidity control runner 2 fixed to the driven member can be prevented from being locked to the fixed shafts 31a and 32a by thermal expansion and contraction and from becoming unrotatable. In addition, the resilient member E, E' is capable of deforming when subjected to forces generated by the movement of the driven member, thereby forcing the driving member to maintain the driving member in engagement with the driven member. This prevents the driving member and the driven member as the transmission assembly from being fitted too tightly or too loosely, thereby reducing the failure rate of the air treatment apparatus 100.
Here, it should be noted that the driving member and the driven member may be: a drive sprocket and a driven sprocket in the chain drive assembly; a driving pulley and a driven pulley in the belt drive assembly; or a driving gear and a driven gear in a gear transmission assembly, etc. In the first and second embodiments described below, a gear transmission assembly is mainly described as an example.
Specifically, as shown in fig. 1 and 2, in the present embodiment, the driving member is a driving gear 11, the driven member is a driven gear 21, the driven gear 21 is engaged with the driving gear 11 and is rotationally driven, and the driving gear 11 and the driven gear 21 are attached to the support body 3 such that the rotation axes L1 and L2 are parallel to each other.
Here, the "parallel to each other" includes not only a strict parallel relationship but also a case of "substantially parallel to each other". That is, in practical applications, for example, due to a backlash in rotation or a process error of the component itself, the rotation axis L1 of the drive gear 11 and the rotation axis L2 of the driven gear 21 may not be completely parallel but may be substantially parallel.
According to the air treatment apparatus 100 of the present embodiment, the drive gear 11 as the driving member and the driven gear 21 as the driven member are engaged with each other such that the rotation axes L1 and L2 thereof are parallel to each other, for example, are aligned with each other, and are always engaged with each other by the elastic member E (see fig. 3). This prevents the drive gear 11 and the driven gear 21, which are transmission units, from being engaged too tightly or too loosely, and thus reduces the failure rate of the air treatment apparatus 100.
The overall structure of the air treatment device 100 of the present invention will be briefly described below with reference mainly to fig. 6 and 8.
As shown in fig. 6, the air treatment device 100 of the present invention mainly includes a lid portion GT and a main body portion BT, and the main body portion BT of the air treatment device 100 will be mainly described in detail below. As shown in fig. 6 to 8, the air treatment apparatus 100 includes a main body BT having an air inlet BTa, a first air outlet BT1, and a second air outlet BT2, and provided with a fan unit 4, a humidity control swivel wheel assembly 2, and a heating unit HT, the fan unit 4 having a fan rotor 4a, an air suction port 41, a first air supply port 42, and a second air supply port 43, the humidity control swivel wheel assembly 2 having an axial direction substantially coincident with an axial direction of the fan rotor 4a of the fan unit 4 (i.e., a rotation axis L4 of the fan rotor 4a is substantially parallel to a rotation axis L2 of a humidity control swivel wheel 22 (driven wheel) of the humidity control swivel wheel assembly 2), the humidity control swivel wheel assembly 2 (specifically, the humidity control swivel wheel 22) having a moisture absorption area 22a and a moisture discharge area 22b adjacent to a circumferential direction of the humidity control swivel wheel assembly 2 (specifically, and when the fan unit 4 is operated, an air flow sucked from the air inlet BTa into the main body BT flows through the moisture absorption area 22a and enters the air suction port 41 of the fan unit 4, the air is divided into two paths, one of which is blown out from the first air blowing port 42 of the fan unit 4, flows through the dehumidifying zone 22b, and is discharged from the first outlet BT1, and the other of which is blown out from the second air blowing port 43 (see fig. 8) of the fan unit 4 toward the second outlet BT2, and is discharged, and the heating unit HT has a heating portion (not shown) that heats at least a part of the dehumidifying zone 22 b.
According to the air treatment apparatus 100 of the present invention, since the driven members in the humidity control turning wheel assembly 2 in the air treatment apparatus 100 are in clearance fit with the fixed shafts 31a, 32a, the humidity control turning wheels 22 fixed to the driven members can be prevented from being locked to the fixed shafts 31a, 32a and being unable to rotate, and further, the heating unit HT is prevented from continuously heating a partial region (the dehumidification region 22b) of the humidity control turning wheels 22 in the humidity control turning wheel assembly 2, so that the risk of fire occurrence is reduced, and the safety, reliability and stability of the apparatus are improved.
Referring back to fig. 1 and 2, the configurations of the drive unit 1, the humidity control swivel assembly 2, and the like according to the present embodiment will be described in detail. The drive assembly 1 includes a drive gear 11, a drive bracket 12, and a motor M (see fig. 3 and 4). The drive gear 11 is, for example, a disk-shaped pinion gear molded from resin, and the drive holder 12 is provided with, for example, an internal space for housing a motor M having a motor shaft, and the drive gear 11 is fixed to the motor shaft so that the motor M directly drives the drive gear 11 to rotate via the motor shaft. Of course, the present invention is not limited to this, and the motor M may drive the drive gear 11 to rotate via an intermediate gear set as one of the modified examples of the present embodiment.
The humidity control swivel assembly 2 includes, in addition to the driven gear 21: a humidity control runner 22, the humidity control runner 22 being provided coaxially with the driven gear 21 as a driven member, and having an axial hole 2h formed in the axial center of the humidity control runner 22 and the driven gear 21; and a sleeve 23, the sleeve 23 being fitted with the spindle hole 2h with play, and the humidity control wheel assembly 2 being pivotally supported by the support body 3 by engaging the spindle hole 2h in which the sleeve 23 is fitted with the fixed shafts 31a, 32a provided on the support body 3.
The driven gear 21 is, for example, a disk-shaped large gear formed by resin molding, and the diameter of the driven gear 21 is much larger than that of the driving gear 11. Thus, even when a motor having a normal rotation speed is used, the humidity control runner 22 provided coaxially with the driven gear 21 can be slowly rotated by the large gear ratio between the drive gear 11 and the driven gear 21.
The humidity control runner 22 has a disk-like structure made of, for example, a zeolite material, and the humidity control runner 22 can adjust the humidity of the air by, for example, releasing moisture during heating and absorbing moisture during cooling.
Although fig. 2 shows a case where the driven gear 21 is directly fitted to the humidity control runner 22, the present invention is not limited thereto. As a modification of the present embodiment, the humidity control wheel 22 and the driven gear 21 may be rotated in synchronization with each other via a connecting member (for example, a straight rod connecting the driven gear 21 and the humidity control wheel 22) such that the driven gear 21 and the humidity control wheel 22 are spaced apart from each other by a predetermined distance.
In the present embodiment, the humidity control swivel assembly 2 includes two bushings 23 having a substantially hollow cylindrical shape, and the two bushings 23 are respectively fitted into the axial hole 2h from the top-bottom direction in fig. 2. Further, since the outer diameter of the portion of the boss 23 fitted into the spindle hole 2h is smaller than the diameter of the spindle hole 2h, the boss 23 can be fitted with play, i.e., with slight play, to the driven gear 21 and the humidity control runner 22 even when the boss 23 is fitted into the spindle hole 2 h. This prevents the humidity control runner 22 from becoming too tightly fitted to the sleeve 23 to be unable to rotate when it expands with heat and contracts with cold, and contributes to further reducing the failure rate of the air treatment apparatus 100.
As shown in fig. 1 and 2, the support body 3 includes an upper housing 31 and a lower housing 32 fixed to each other by, for example, screws, wherein an upper fixed shaft 31a of fixed shafts 31a, 32a to which a shaft hole 2h of the sleeve 23 is fitted is provided to the upper housing 31, and a lower fixed shaft 32a is provided to the lower housing 32. In the actual installation process, after the upper fixing shaft 31a and the lower fixing shaft 32a are inserted into the shaft sleeve 23 in a manner of having substantially no clearance (the term "substantially no clearance" as used herein means that no clearance is caused by process tolerance of parts and thermal expansion and contraction of plastic products is included) and fixed by screws or snaps, the upper fixing shaft 31a and the lower fixing shaft 32a are fixed to the fan housing 33 (or other components of the air treatment device 100). The upper and lower casings 31 and 32 support the driven gear 21 and the humidity control rotor 22 so as to be freely rotatable, by pivotally supporting the humidity control rotor assembly 2 by the upper and lower fixed shafts 31a and 32 a.
In addition to the upper and lower casings 31, 32, the support body 3 also comprises a fan casing 33, the drive assembly 2 being mounted to this fan casing 33. Specifically, as shown in fig. 2, the fan casing 33 has a substantially hollow ring shape, the fan unit 4 is attached directly below the fan casing 33, and the air taken in from the outside by the fan unit 4 flows downward through the drive unit 1 and the humidity control swivel assembly 2, and then flows through the hollow member of the fan casing 33. A lower casing 32 having a fan shape in plan view is attached to an upper peripheral portion of the fan casing 33 by screws, for example, and the drive unit 1 is attached to a position radially opposed to a fixed position of the lower casing 32, that is, the drive unit 1 and the humidity control swivel assembly 2 are attached to the fan casing 33 so that a part of each is exposed to a hollow portion of the fan casing 33. Thus, by mounting the drive unit 1 to the fan housing 33, the drive unit 1 can be directly radiated by the existing fan unit 4 without additionally providing a heat radiation member and a support member for the drive unit 1, which contributes to a reduction in the number of parts of the air treatment apparatus 100, and reduces the manufacturing cost while achieving a reduction in the size of the apparatus.
In the present embodiment, the support body is assembled by the upper case 31, the lower case 32, and the fan case 33 being separated by screws or the like. In the case of this separate assembly, it contributes to a reduction in the cost of manufacturing a complicated mold. However, the present invention is not limited to this, and the support member may be formed by integrally molding the upper casing 31, the lower casing 32, and the fan casing 33, for example. In this case, the integral molding contributes to a reduction in the number of parts of the air treatment device 100.
Hereinafter, a specific configuration of the first stopper portion 3S and the second stopper portion 1S according to the present embodiment will be described mainly with reference to fig. 2 and 3.
In the present embodiment, the support body 3 is provided with the first stopper portion 3S, the drive unit 1 is provided with the second stopper portion 1S, and the first stopper portion 3S and the second stopper portion 1S are elastically engaged by the elastic member E. Thus, the elastic engagement between the two stopper portions 3S and 1S and the elastic member E can prevent the driving gear 11 and the driven gear 21 from being excessively tightly or loosely engaged with each other with a simple structure.
Specifically, as shown in fig. 2, in the present embodiment, the first stopper portion 3S is a columnar portion, and the second stopper portion 1S is a hollow clamping portion that is fitted to the columnar portion with the elastic member E interposed therebetween. Thus, the driving gear 11 and the driven gear 21 can be engaged with each other well by the simple structure in which the elastic member E is sandwiched between the columnar portion and the hollow sandwiching portion.
More specifically, in the present embodiment, three columnar portions as the first stopper portions 3S are provided in the peripheral portion of the annular fan casing 33 of the support body 3, and screw holes are provided in the three columnar portions for screws to be screwed; three hollow clamping portions as second stoppers 1S are provided at corresponding positions of the drive bracket 12 of the drive unit 1, and the hollow portions of the three hollow clamping portions are formed, for example, in a substantially circular shape (i.e., a major arc) having a notch in a plan view.
Further, it is preferable that the maximum value of the amount by which the elastic member E is deformable is larger than the value of the play between the driven part (i.e., the driven gear 21) and the fixed shafts 31a, 32 a. Specifically, for example, in the present embodiment, when the rubber ring as the elastic member E is fitted to the columnar portion D1 (i.e., after the installation is completed), the allowance with which the rubber ring as the elastic member E can be further expanded or contracted is larger than the maximum distance by which the driven gear 21 can move in the direction intersecting the rotation axis L2 thereof.
More preferably, the outer diameter D1 of the columnar portion is smaller than the inner diameter D2 of the hollow clamping portion, and the following relationship is satisfied: D2-D1 is not less than 4mm and not more than 12 mm. Accordingly, by setting the dimensional relationship between the columnar portion and the hollow clamping portion as described above, the drive gear 11 and the driven gear 21 can be engaged with each other with an appropriate degree of tightness. In addition, in the present embodiment, the elastic member E is a rubber ring. Thus, the elastic fitting between the first stopper portion 3S and the second stopper portion 1S can be achieved with a simple rubber ring elastic material.
With continued reference to fig. 2 and 3, the steps of mounting the drive assembly 1 will be explained. When the driving assembly 1 is installed, firstly, a rubber ring as an elastic component E is sleeved into the three columnar parts as the first limiting parts 3S; then, three hollow clamping parts as second limiting parts 1S are sleeved in and clamp the rubber ring; finally, the three screws on which the spacers are sleeved are screwed into the threaded holes of the three columnar parts respectively, so that the driving assembly 1 is mounted.
By elastically and/or loosely attaching the drive unit 1 to the fan housing 33 of the support body 3 as described above, when the drive gear 11 of the drive unit 1 meshes with the driven gear 21 of the humidity control swivel assembly 2 similarly attached to the fan housing 33, the drive gear 11 can reciprocate in a direction intersecting the rotation axis line L1 thereof (specifically, in a direction substantially perpendicular to the rotation axis line L1, more specifically, in a direction in which the axial center of the drive gear 11 and the axial center of the driven gear 21 are connected to each other), and thereby the drive gear 11 and the driven gear 21 are prevented from being excessively tightly or loosely meshed due to the respective manufacturing tolerances, thermal expansion, and cold contraction.
Although the first embodiment in which the first stopper portion 3S is a columnar portion and the second stopper portion 1S is a hollow clamping portion has been described above, the present invention is not limited thereto. As a modification of the first embodiment, for example, the first stopper portion 3S may be a hollow clamping portion and the second stopper portion 1S may be a columnar portion. The number of the columnar portions and the hollow sandwiching portion is not limited to three, and may be two or four or more. The specific shape of the hollow clamping portion is not limited to the substantially circular shape having the notch in the plan view, and may be, for example, a complete hollow columnar shape without a notch. The elastic member E is not limited to a rubber ring, and may be, for example, an annular balloon or a member having elasticity such as a sponge.
[ second embodiment ]
Hereinafter, a specific configuration of an air treatment apparatus according to a second embodiment of the present invention will be described with reference mainly to fig. 4 to 5B. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description thereof is omitted.
As shown in fig. 4, 5A, and 5B, the second embodiment is different from the first embodiment mainly in the first stopper portion 3S ', the second stopper portion 3S ', the elastic member E ', and the like.
As shown in fig. 5A and 5B, in the present embodiment, the first stopper portion 3S ' is provided with a first projection 3S ' 1, the second stopper portion 1S ' is provided with a second projection 1S ' 1, and the first projection 3S ' 1 and the second projection 1S ' 1 face each other so that the elastic member E ' is sleeved. In addition, the first stopper portion 3S ' is further provided with a stopper projection 3S ' 2, the second stopper portion 1S ' is further provided with a stopper groove 1S ' 2, the stopper groove 1S ' 2 is opened in a direction parallel to the facing direction F of the first projection 3S ' 1 and the second projection 1S ' 1, and the stopper projection 3S ' 2 is engaged with the stopper groove 1S ' 2.
Specifically, as shown in fig. 5A, the first stopper portion 3S 'includes a first projection 3S' 1, a stopper projection 3S '2, and a first stopper portion main body 3S' 3. The first stopper body 3S' 3 is substantially L-shaped as a whole in a plan view (viewed from above in fig. 5A), and is provided in the fan housing 33 of the support body 3. The first protrusion 3S '1 is disposed on a side where a overlooking short side of the L-shaped first limiting part body 3S' 3 is located. The stopper projection 3S '2 is provided on the side of the L-shaped first stopper body 3S' 3 on which the overlooking long side is located, extending in the direction parallel to the opposing direction F.
As shown in fig. 5B, the second position-limiting portion 1S 'includes a first protrusion 1S' 1, a position-limiting groove 1S '2, and a second position-limiting portion main body 1S' 3. The second stopper body 1S' 3 is substantially L-shaped as a whole in a plan view (viewed from above in fig. 5A), and is provided to the drive bracket 12 of the drive unit 1. The stopper groove 1S '2 is provided on the side of the L-shaped first stopper main body 1S' 3 where the overlooking long side is located, extending in the direction parallel to the opposing direction F. The second protrusion 1S '1 is disposed on a plane where the overlooking short side of the L-shaped first limiting part body 1S' 3 is located.
Here, in the present embodiment, the elastic member E ' is a spring (of course, the elastic member E ' may be rubber, but hereinafter, a case where the elastic member E ' is a spring will be mainly described). Thus, the elastic fitting between the first stopper portion 3S 'and the second stopper portion 1S' can be achieved with a simple elastic material.
The mounting procedure of the drive unit 1 will be described below with reference to fig. 4. First, the drive bracket 12 of the drive assembly 1 is loosely mounted to the fan housing 33 of the support body 3 by screws so that the drive assembly 1 as a whole can be slightly moved in a direction (for example, the opposite direction F) intersecting (perpendicular to) the rotation axis L1; meanwhile, the first bulge 3S '1 and the second bulge 1S' 1 are aligned and opposite along the opposite direction F, and the limiting bulge 3S '2 is clamped in the limiting groove 1S' 2; then, both ends of a spring as an elastic member E ' are respectively fitted over the first projection 3S ' 1 and the second projection 1S ' 1, thereby completing the installation of the driving assembly 1.
According to the air treatment device 100 of the present embodiment, the two first projections 3S '1 and the two second projections 1S' 1 facing each other are provided, so that the spring can be reliably fitted, and the spring can be reliably restrained, and the spring can reliably exert the elastic restraining function on the movement of the active member together with the two projections 3S '1 and 1S' 1. Further, by providing the stopper projection 3S '2 and the stopper groove 1S' 2 engaged with each other in the direction parallel to the opposing direction F, the two stopper portions 3S ', 1S' can be reliably reciprocated in the direction parallel to the opposing direction F, and the spring torsion caused by the left and right rocking of the drive unit 1 can be avoided, thereby reliably preventing the drive gear 11 and the driven gear 21 from being excessively tightly or loosely engaged with each other.
Further, after the driving assembly 1 is mounted, the elastic member E' (i.e., the spring) can be contracted or extended in a state where the driving gear 11 is engaged with the driven gear 21 and rotated. That is, when the drive gear 11 and the driven gear 21 rotate in mesh, the spring is always in a state of applying an elastic force to the first stopper portion 3S 'and the second stopper portion 1S'. Thereby, as compared with the case where the spring is switched between the natural length state and the contracted/expanded state, the spring can be prevented from falling out from between the first projection 3S '1 and the second projection 1S' 1, thereby further reliably preventing the driving gear 11 and the driven gear 21 from being engaged too tightly or too loosely.
As a modification of the present embodiment, the drive unit 1 may be inclined with respect to the humidity control swivel assembly 2 (for example, inclined so that the center of gravity of the drive unit 1 is biased toward the humidity control swivel assembly 2), and an engaging structure (for example, a bump or a sheet protruding perpendicularly to the opposing direction F) for fixing a spring may be provided at the first protrusion 3S '1 and the second protrusion 1S' 1. In this case, when the driven part moves away from the driving part, the driving assembly 1 may extend the elastic member by its own weight to engage the driving part with the driven part, thereby further reliably preventing the driving part from being fitted too tightly or too loosely with the driven part.
In addition, in the present embodiment, the minimum length of the elastic member E ' (i.e., the spring) in the compressed state is equal to or greater than the sum of the lengths (of the first projection 3S ' 1 and the second projection 1S ' 1 (projecting in the opposing direction F). Thus, as compared with the case where the minimum length of the spring in the compressed state is smaller than the sum of the lengths of the two projections 3S '1, 1S' 1, the first projection 3S '1 and the second projection 1S' 1 can be prevented from abutting against each other in the extreme compressed state of the elastic member, and damage and noise due to collision caused by the abutment can be avoided, thereby further reliably preventing the drive gear 11 and the driven gear 21 from being excessively tightly meshed.
Here, it should be noted that the maximum value of the amount by which the elastic member E' can be deformed is larger than the value of the play between the driven member (i.e., the driven gear 21) and the fixed shafts 31a, 32 a. Specifically, for example, in the present embodiment, in a case where the elastic member E 'is fitted over the first projection 3S' 1 and the second projection 1S '1 (i.e., after the mounting is completed), the allowance by which the spring as the elastic member E' can be further extended or contracted is larger than the maximum distance by which the driven gear 21 can move in the direction intersecting the rotation axis L2 thereof.
This ensures that the backlash of the driven gear 21 is compensated for within the elastic range of the elastic member E', thereby further reliably preventing the drive gear 11 from meshing too tightly with the driven gear 21.
Although the second embodiment in which the first stopper portion 3S 'is provided with the stopper projection 3S' 2 and the second stopper portion 1S 'is provided with the stopper groove 1S' 2 has been described above, the present invention is not limited thereto. As one modification of the second embodiment, for example, the first stopper portion 3S 'may be provided with a stopper groove and the second stopper portion 1S' may be provided with a stopper projection.
In the present invention, the embodiments may be freely combined, or may be appropriately modified or omitted within the scope of the present invention.
