Detailed Description
Embodiments of the air conditioning unit of the present disclosure are described below with reference to the drawings.
Fig. 1 to 5 show a first embodiment of an air conditioning unit of the present disclosure.
As shown in fig. 1 to 5, the air conditioning unit 1 includes a cylindrical casing 2 shown in the vertical direction in the drawing, a blower 3 provided at the lower end of the casing 2 and configured to send air into the casing 2, and a reverse bowl-shaped end cover 4 configured to close the upper end of the casing 2.
The housing 2 includes: a cylindrical casing body 5 having a blower 3 at a lower end and an external thread cylinder 5a having a diameter smaller than the outer shape at an upper end; a fastening ring 8 having an inner surface provided with an internal thread 7 screwed to the external thread 6 on the outer periphery of the external thread cylinder 5a of the housing main body 5; and a cylindrical body 9 which is fitted to the fastening ring 8 so as to be rotatable relative to each other and not movable relative to each other in the axial direction, and the upper end of which is closed by the end cap 4. The end cap 4, the housing main body 5, the fastening ring 8, and the cylinder 9 are desirably formed of a hard synthetic resin material, but some are also formed of a metal material.
The blower 3 is configured by providing a motor 11 and a fan 12 in a fan housing 10 having an expanded diameter blade portion 10a, and by abutting the expanded diameter blade portion 10a against the lower end of the housing body 5, fitting a portion on the air outlet side in the fan housing 10 into the housing body 5, and engaging an elastic engagement claw 10b provided in a portion of the fan housing 10 with an engagement protrusion 5b provided on the inner surface of the housing body 5, the blower is mounted on the housing body 5. The blower 3 rotates by the fan 12 to mainly convey air in the direction of the rotation axis of the fan.
The blower 3 may be mounted on the housing body 5 by screwing a male screw portion (not shown) provided on the outer peripheral surface of the fan housing 10 with a female screw portion (not shown) provided on the inner surface of the housing body 5 (see fig. 10).
A 1 st exhaust port 13 communicating with a duct 31 described later is provided in a part of the outer peripheral surface of the housing main body 5. The 1 st exhaust port 13 has an oval shape elongated in the circumferential direction of the housing main body 5, but may have other shapes such as a circular shape depending on the shape of the opening of the duct 31.
The fastening ring 8 has an enlarged diameter flange 8b at the lower end of a cylindrical portion 8a having a female screw portion 7 provided on the inner surface thereof. The air conditioning unit 1 can be easily attached to the attached matter by inserting the male screw cylindrical portion 5a of the housing main body 5 into an attachment hole (not shown) provided in a garment such as an air conditioning suit or other attached matter (not shown), and sandwiching the attached matter between the enlarged diameter flange 8b of the fastening ring 8 and the stepped portion 5c at the upper end of the housing main body 5, thereby fastening the fastening ring 8 to the male screw cylindrical portion 5 a. The one-dot chain line shown in fig. 1 to 4 shows the sandwiching position E of the attached matter.
An annular projection 8c is provided on the outer periphery of the upper end portion of the tubular portion 8a in the fastening ring 8, and the tubular portion 9 is relatively rotatable with respect to the fastening ring 8 and is not relatively movable in the axial direction by engagement of the annular projection 8c with the upper end of an inward stepped portion 9a provided on the inner surface of the lower end portion of the tubular portion 9.
Instead of engaging the annular ridge 8c with the upper end of the inward stepped portion 9a of the cylinder 9, the annular ridge 8c may be engaged with an annular groove (not shown) provided in the inner surface of the lower end portion of the cylinder 9, and an inward elastic engagement claw (not shown) provided in the lower end of the cylinder 9 may be engaged with an annular groove (not shown) provided in the outer peripheral surface of the cylinder portion 8a of the fastening ring 8.
The partition wall 14, which faces in a direction orthogonal to the central axis L (fig. 3) of the housing 2, is provided at the upper end portion of the cylinder 9 in the housing 2 so as to be spaced apart from the end cover 4 in the central axis L direction.
That is, the partition wall 14 is oriented in a direction perpendicular to the blowing direction of the blower 3 facing the same direction as the central axis L of the housing 2, and divides the interior of the housing 2 into a 1 st chamber a on the blower 3 side and a 2 nd chamber B on the end cover 4 side. In this way, by providing the partition wall 14 in the housing 2 so as to face in the direction orthogonal to the blowing direction of the blower 3 and providing the 1 st chamber a and the 2 nd chamber B so as to be aligned in the direction of the central axis L of the housing 2, it is possible to ensure a wide space for providing the later-described thermoelectric devices 17 in the partition wall 14 while achieving the thinning of the housing 2. Furthermore, a plurality of thermoelectric devices 17 can be provided in the narrow case 2, and the thermal efficiency can be improved.
The partition wall 14 does not have to be exactly orthogonal to the blowing direction of the blower 3 or the center axis L of the housing 2, and may be inclined to some extent.
In this embodiment, the lower surface of the outer peripheral portion of the partition wall 14 is fixed to the upper end surface of the cylinder 9 with an adhesive, the outer peripheral portion of the inverted bowl-shaped end cap 4 is brought into contact with the upper surface of the outer peripheral portion of the partition wall 14, and the end cap 4 is fixed to the partition wall 14 with a screw 15 (see fig. 4). However, the partition wall 14 may be fixed to a middle portion of the inner surface of the cylinder 9, and the end cap 4 may be detachably attached to the upper end of the cylinder 9.
A pair of right and left square holding holes 16 (see fig. 4) are provided in the center of the partition wall 14, and square plate-shaped peltier elements 18 in a thermoelectric device 17 for performing heat transfer between the air in the 1 st chamber a and the air in the B are fitted and held in the holding holes 16. The peltier element 18 is an element capable of generating a difference heat between the front and back surfaces of the peltier element by applying electric power, and the upper surface and the lower surface can be made to be a heat absorbing surface and a heat dissipating surface by switching the polarity of the electric power, whereas the upper surface and the lower surface can be made to be a heat dissipating surface and a heat absorbing surface, respectively. The lower end opening of the holding hole 16 is provided with a small-sized inward flange 16a, and a peripheral edge portion of the peltier element 18 is placed on the inward flange 16a (see fig. 4).
Each thermoelectric device 17 includes the peltier element 18, a 1 st heat sink 19 made of a copper heat sink provided on the lower surface thereof, and a 2 nd heat sink 20 made of a copper heat sink provided on the upper surface of the peltier element 18. The peltier element 18 and the 1 st heat sink 19 are contacted by a heat dissipating grease in which a metal filler, a metal oxide filler, or the like is added to the modified silicone. Similarly, the peltier element 18 and the 2 nd heat sink 20 are also in contact with each other by heat dissipation grease having excellent heat conductivity. By filling the heat dissipation grease in the contact interface, heat conduction loss due to surface roughness or the like of the contact surfaces of the peltier element 18, the 1 st heat sink 19, and the 2 nd heat sink 20 can be reduced, and heat conduction efficiency can be improved. It should be noted that a heat sink may be used instead of the heat dissipation grease. The thermoelectric devices 17 are not limited to those having the peltier elements 18, and may be any type as long as they can perform heat transfer between the air in the 1 st chamber a and the air in the 2 nd chamber B.
As shown in fig. 3, a pair of front and rear guide pieces 22 provided with a plurality of ventilation openings 21 are provided on the upper surface of the partition wall 14 so as to sandwich the two thermoelectric devices 17 from front to rear.
As shown in fig. 4, a boss portion 23 is provided between the left and right holding holes 16 on the upper surface of the partition wall 14 and at the outer side portions of the left and right holding holes 16, and a screw hole 23a is provided at the upper end of the boss portion 23.
A pressing plate 24 is disposed above the left and right thermoelectric devices 17 in the left and right directions, and a center portion thereof is screwed to the partition wall 14 by a screw 25 screwed to a screw hole 23a of the boss portion 23 in the center, so that the peltier element 18 and the 2 nd heat sink 20 in the left and right thermoelectric devices 17 are sandwiched and held by the partition wall 14 and the pressing plate 24.
The both side portions of the pressing plate 24 are screwed to the partition wall 14 by the screws 15, and are fixed to the partition wall 14 together with the end cover 4. The screws 15 pass through the end cover 4 and the pressing plate 24, and are screwed into screw holes 23a of the left and right boss portions 23.
As shown in fig. 3, the air blowing guide 26 of the radiator 19 covering the lower portions of the left and right thermoelectric devices 17 is fixed to the lower surface of the partition wall 14 by a pair of front and rear screws 27.
As shown in fig. 5, the blower guide 26 includes a bottom sheet 26a covering the blower 3 side surface of the 1 st radiator 19, side sheets 26b covering the left and right side surfaces of the 1 st radiator 19, and a front sheet 26c covering the front surface of the 1 st radiator 19. The center portion of the air guide 26 in the lateral direction is provided with a pair of front and rear boss portions 26d, 26e having screw holes 28 at the upper ends, and the air guide 26 is fixed to the partition wall 14 by screwing the screws 27 penetrating the partition wall 14 into the screw holes 28.
A rib 26f is provided at the center of the bottom plate 26a of the air guide 26 so as to extend forward from the boss portion 26e at the rear. When the air blowing guide 26 is attached to the lower surface of the partition wall 14, the rib 26f is located between the 1 st radiator 19 on the left and right.
The upper surface of the bottom plate 26a of the air guide 26 is substantially horizontal, while the lower surface is slightly inclined in the rear direction. That is, the backsheet 26a has a wedge shape with a thickened wall thickness rearward.
The rear surface of the air guide 26 is open except for the boss portion 26e, which constitutes an air inlet 29 (see fig. 5) into the air guide 26.
An elliptical duct connecting hole 30 elongated in the left-right direction is provided in the front portion of the bottom plate 26a of the air blowing guide 26, which is located forward and away from the air inlet 29, and a tip end portion of a duct 31 having an elliptical cross section is fitted and connected thereto from below.
As shown in fig. 3, the duct 31 is inclined downward toward the front, and the base end portion is formed integrally with the housing main body 5 and opens at the 1 st exhaust port 13 of the housing main body 5.
The duct 31 communicates the inside of the air guide 26 in the 1 st chamber a of the casing 2 with the outside of the casing 2, and forms a 1 st air passage C, and part of the air sent from the blower 3 is guided to the outside of the casing 2 through the 1 st air outlet 13 by the thermoelectric device 17 in the 1 st chamber a.
An oval vent 32 elongated in the left-right direction is provided at the rear of the partition wall 14, and the vent 32 guides the other part of the air sent from the blower 3 to the 2 nd chamber B.

By providing these two arrows 34 and 35, when an attached matter (not shown) such as clothing is sandwiched between the case body 5 and the fastening ring 8 is fastened to the externally threaded cylindrical portion 5a, even if the duct 31 cannot be visually recognized from the outside, the duct connection hole 30 of the blower guide 26 and the fitting portion of the tip portion integrated with the case body 5 can be fitted to each other without viewing the duct 9 and the case body 5 by holding the duct 9 at an appropriate position with respect to the case body 5 with the two arrows 34 and 35 as marks. Operability is improved.
Fig. 6 is a diagram showing an example of a power system in an air conditioning unit. In fig. 1 to 5, wiring and other power systems in the air conditioning unit 1 are omitted, but as shown in fig. 6, the peltier element 18 in each thermoelectric device 17 is connected to a power source 46 (battery) through a power switch 38, a booster circuit 47, and a peltier control circuit 37A. The motor 11 in the blower 3 is connected to a power source 46 (battery) via a power switch 38 and a motor control circuit 37B. The power switch 38 is a switch for supplying/shutting off electric power supplied from the power source 46 to the peltier element 18 and the motor 11.
The peltier control circuit 37A has the following functions: the power supplied to the peltier element 18 is adjusted by operating the voltage adjustment knob 41 connected to the peltier control circuit 37A, thereby adjusting the differential heat of both sides of the peltier element 18. That is, the characteristics of the thermoelectric device 17 can be adjusted by operating the voltage adjustment knob 41. The peltier control circuit 37A has a function of switching the polarity of the electric power supplied to the peltier element 18 by switching the polarity switching switch 40 connected to the peltier control circuit 37A.
The motor control circuit 37B has a function of adjusting the number of motor revolutions by operating the air volume adjustment knob 39 connected to the motor control circuit 37B. That is, the air volume of the blower 3 can be adjusted by operating the air volume adjustment knob 39.
The voltage boosting circuit 47 is a circuit that boosts the voltage of the electric power supplied from the power source 46, for example, a circuit that boosts from 5V to 12V. The booster circuit 47 is a circuit including an inductor and a transistor. Since the voltage of the electric power supplied from the power supply 46 to the peltier element 18 is boosted by the voltage boosting circuit 47, the difference between the front and back sides of the peltier element 18 can be increased as compared with the case where the voltage is not boosted. For this reason, the heat absorption and radiation characteristics of the peltier element 18 can be improved.
The booster circuit 47 is required to be used after cooling because the circuit generates heat by boosting. By disposing the booster circuit 47 in the 2 nd chamber B, the booster circuit 47 can be cooled by the air sent from the blower 3 through the 2 nd chamber B, and the boosting characteristic of the booster circuit 47 can be maintained for a long period of time. The booster circuit 47 may be disposed in the 2 nd air duct D. In this case, for example, when the polarity switch 40 is "positive", the booster circuit 47 is further cooled by the air sent from the blower 3 and cooled by the thermoelectric device 17, so that the boosting characteristic of the booster circuit 47 can be maintained more effectively over a long period of time. Further, when the polarity switch 40 is "reverse", the booster circuit 47 is further cooled by the air sent from the blower 3 and cooled by the thermoelectric device 17, so that the boosting characteristic of the booster circuit 47 can be maintained more effectively for a long period of time.
The booster circuit 47 may be disposed in the 1 st room a or in the 1 st air duct C. The booster circuit 47 is cooled by the air sent from the blower 3 through the 1 st chamber a or the 1 st air passage C, and the booster characteristic of the booster circuit 47 can be positioned for a long time. In this case, since the air that has cooled the booster circuit 47, that is, the air that has been warmed up, does not flow into the 2 nd air duct D, for example, when the polarity switch 40 is "positive", the temperature of the cool air sent from the 2 nd air outlet 33 of the 2 nd air duct D can be kept low.
The controller 36 includes a peltier control circuit 37A, a polarity switch 40, a voltage adjustment knob 41, a motor control circuit 37B, and an air volume adjustment knob 39. The peltier control circuit 37A, the polarity switch 40, and the voltage adjustment knob 41 may be physically different controllers from the motor control circuit 37B and the air volume adjustment knob 39. The power supply 46 may be constituted by two physically separate batteries corresponding to the respective controllers. The electronic components may be covered with a conductive member such as aluminum foil (not shown), so as to prevent electromagnetic interference generated when the voltage is increased.
Next, the operation of the air conditioner unit 1 will be described based on the block diagram of the power system shown in fig. 6. Since the operation of the air conditioning unit 1 is simple, the flow chart is omitted.
When the power switch 38 is turned on, the motor 11 and the peltier element 18 are energized.
The energization of the motor 11 is controlled to be the air volume set by the air volume adjustment knob 39.
The energization of the peltier element 18 is controlled to be a polarity set by the polarity change switch 40 or to be a voltage set by the voltage adjustment knob 41.
For example, when the polarity switch 40 is "positive", the polarity display 44 shows "positive", and the peltier element 18 absorbs heat of the air on the 2 nd air passage D side and radiates heat to the air on the 1 st air passage C side; when the polarity switch 40 is "reverse", the polarity display 44 shows "reverse", and the peltier element 18 absorbs heat of the air on the 1 st air path C side and radiates heat to the air on the 2 nd air path D side.
By the operation of the blower 3, air is sent into the casing 2, a part of which is discharged from the 1 st exhaust port 13 to the outside of the casing 2 through the 1 st ventilation path C, and another part of which is discharged to the outside through the 2 nd ventilation path D from the 2 nd exhaust port 33 provided in the end cover 4.
When the polarity switch 40 is "positive", the air passing through the 2 nd air path D is absorbed by the thermoelectric device 17, and the absorbed heat is emitted to the air passing through the 1 st air path C. Therefore, the temperature of the air discharged from the 1 st air outlet 13 is higher than the temperature of the air conveyed by the blower 3, and the temperature of the air discharged from the 2 nd air outlet 33 of the end cover 4 is lower than the temperature of the air conveyed by the blower 3.
Further, when the polarity switch 40 is "reverse", the air passing through the 1 st air path C is absorbed by the thermoelectric device 17, and the absorbed heat is radiated to the air passing through the 2 nd air path D. Therefore, the temperature of the air discharged from the 1 st air outlet 13 is lower than the temperature of the air conveyed by the blower 3, and the temperature of the air discharged from the 2 nd air outlet 33 of the end cover 4 is higher than the temperature of the air conveyed by the blower 3.
When the air conditioning unit 1 is attached to an air conditioning suit (not shown) such that the end cover 4 is positioned inside the suit and the blower 3 is positioned outside the suit, air having a temperature lower than the outside air is fed into the suit when the polarity switch 40 is set to "positive", and cooling can be performed in the suit. At this time, air having a higher temperature than the outside air is discharged from the duct 31.
When the polarity switch 40 is turned "reverse" from this state, air having a higher temperature than the outside air is supplied into the clothes, and heat can be supplied into the clothes. At this time, air having a temperature lower than that of the outside air is discharged from the duct 31.
When the power switch 38 is turned off, the energization of the motor 11 and the peltier element 18 is stopped.
Since the first embodiment of the air conditioning unit of the present disclosure is configured as above, the following specific effects can be achieved.
(1) The plurality of thin ventilation ducts C, D can be formed by only a single blower 3, and the entire apparatus can be reduced in size, thickness, and simplified in structure.
(2) Since the air supply guide 26 and the duct 31 are provided, most of the air passing through the 1 st air passage C can be in contact with the thermoelectric device 17 in the 1 st chamber a, and the heat efficiency can be improved.
(3) Since the tubular body 9 is fitted so as to be relatively rotatable with respect to the fastening ring 8 and so as to be relatively immovable in the axial direction, the air conditioning unit 1 can be easily attached to the attached matter by sandwiching clothes such as air conditioning clothes and other attached matter between the housing main body 5 and the fastening ring 8.
(4) Since the marks 34 and 35 showing the proper positional relationship between the blower guide 26 and the duct 31 and the housing main body 5 are attached to the outer peripheral surface of the housing main body 5 and the outer peripheral surface of the cylinder 9, the housing main body 5 and the cylinder 9 are joined by aligning the marks, and the duct 31 and the blower guide 26, which are difficult to be visually recognized from the outside, can be connected without being viewed, and the operability is improved.
In the second embodiment of the air conditioning unit of the present disclosure shown in fig. 10, even when the duct 31 is integrally formed with the air blowing guide 26 and the tip end portion of the duct 31 is fitted to the 1 st air outlet 13 of the housing main body 5, the housing main body 5 and the cylinder 9 are coupled by the alignment marks 34 and 35, and connection between the duct 31 and the 1 st air outlet 13 of the housing main body 5, which is difficult to be seen from the outside, can be performed without being seen, and operability is improved.
(5) Since the thermoelectric device 17 includes the peltier element 18, the 1 st radiator 19, and the 2 nd radiator 20, heat absorbed from the air in the 2 nd air passage D can be efficiently transferred to the air in the 1 st air passage C.
(6) Since the power supply 46 and the controller 36 are connected to the blower 3 and the thermoelectric device 17 by wires, and the controller 36 has the polarity switch 40 for switching the polarity of the power supplied to the thermoelectric device 17, cold air or warm air can be sent from the 2 nd air outlet 33 of the 2 nd air duct D by switching the polarity switch 40.
(7) Further, by disposing the booster circuit 47 in the 2 nd chamber B and cooling the booster circuit 47 with the air sent from the blower 3 through the 2 nd chamber B, the booster characteristic of the booster circuit 47 can be maintained for a long period of time, and the characteristic of the peltier element 18 can be maintained.
As shown in fig. 7, the controller 36 may further include a display unit that displays temperature information from a temperature sensor connected to the controller 36 as an in-clothes temperature and an outside air temperature, in addition to the air volume adjustment knob 39, the polarity change switch 40, and the voltage adjustment knob 41. The user can adjust the air volume knob 39 or the voltage knob 41 while looking at the temperature in the clothes or the temperature of the outside air. Here, fig. 7 is a schematic front view showing the controller 36 used in the air conditioning unit 1 of the present disclosure.
Fig. 8 shows other examples of power systems in an air conditioning unit.
As shown in fig. 8, the controller 36 may be configured by a general-purpose central processing unit such as a CPU. The controller 36 includes a power switch 38, an air volume control knob 39, a polarity switch 40, a voltage control knob 41, a power display lamp 42, an air volume display 43, a polarity display 44, and a voltage display 45, which are connected to the control circuit 37. The power display light 42 is an indicator that lights up when the power switch 38 is turned on. The polarity display 44 is an indicator that displays the polarity of the power supplied to the peltier element 18.
The peltier element 18 in each thermoelectric device 17 is connected to a power source 46 (battery) through a booster circuit 47 and a power semiconductor 48A. The motor 11 in the blower 3 is connected to a power source 46 (battery) via a power semiconductor 48B. The power semiconductors 48A and 48B are transistors such as FETs, and are connected to the control circuit 37, respectively, and control the power from the power source 46 by a signal from the control circuit 37 to supply the power to the peltier element 18 and the motor 11.
The energization of the motor 11 is controlled to be the air volume set by the air volume adjustment knob 39, and the air volume is displayed on the air volume display 43 such that, for example, a pointer (not shown) shows a corresponding value on a scale from small to large.
The energization of the peltier element 18 is controlled to be a polarity set by the polarity change switch 40 or to be a voltage set by the voltage adjustment knob 41.
For example, when the polarity switch 40 is "positive", the polarity display 44 shows "positive", and the peltier element 18 absorbs heat of the air on the 2 nd air passage D side and radiates heat to the air on the 1 st air passage C side; when the polarity switch 40 is "reverse", the polarity display 44 shows "reverse", and the peltier element 18 absorbs heat of the air on the 1 st air path C side and radiates heat to the air on the 2 nd air path D side.
The energization voltage of these peltier elements 18 is set by a voltage adjustment knob 41, and the voltage is displayed on a voltage display 45. The display may be performed by, for example, a pointer (not shown) showing a corresponding value in a scale from weak to strong.
Since the power semiconductors 48A and 48B also emit heat by operation, the power semiconductors 48A and 48B may be disposed in the 2 nd chamber B. With this configuration, the power semiconductors 48A and 48B are cooled by the air sent from the blower 3 through the 2 nd chamber B, and the characteristics (switching characteristics, etc.) of the power semiconductors 48A and 48B can be maintained for a long period of time. The power semiconductors 48A and 48B may be disposed in the 2 nd air duct D. In this case, for example, when the polarity switch 40 is "positive", the power semiconductors 48A and 48B are further cooled by the air sent from the blower 3 and cooled by the thermoelectric device 17, and the characteristics of the power semiconductors 48A and 48B can be maintained more effectively over a long period of time. When the polarity switch 40 is "reverse", the power semiconductors 48A and 48B are further cooled by the air sent from the blower 3 and cooled by the thermoelectric device 17, and the characteristics of the power semiconductors 48A and 48B can be maintained more effectively over a long period of time.
The power semiconductors 48A and 48B may be disposed in the 1 st chamber a or the 1 st ventilation path C. The power semiconductors 48A and 48B are cooled by the air sent from the blower 3 through the 1 st chamber a or the 1 st air duct C, and the characteristics of the power semiconductors 48A and 48B can be maintained for a long period of time. In this case, since the air that has cooled the power semiconductors 48A, 48B, that is, the warmed air does not flow into the 2 nd air duct D, for example, when the polarity switch 40 is "positive", the temperature of the cool air sent from the 2 nd air outlet 33 of the 2 nd air duct D can be kept low.
Although other examples of the power system in the air conditioner 1 have been described above, the terminal device 60 may be provided with a part of the functions of the controller 36. Fig. 9 is a schematic front view showing a terminal device 60 used in the air conditioning unit of the present disclosure; for example, an air volume adjustment knob 39 of the controller 36. The function of the voltage adjustment knob 41 may be included in the terminal device 60.
The terminal device 60 may use a general-purpose computer terminal such as a smart phone or a tablet computer. The terminal device 60 and the controller 36 may be connected by a wireless standard such as bluetooth (registered trademark).
As shown in fig. 9, the terminal device 60 displays temperature information from a temperature sensor connected to the controller 36 on the screen, and controls the energization of the motor 11 to set the air volume by sliding a gauge of "fan output" corresponding to the air volume adjustment knob as the temperature in the clothes and the outside air temperature.
Further, by inputting the set temperature, the control circuit 37 may also appropriately switch the polarity of the peltier element 18 based on the information of the outside air temperature or the temperature inside the clothes, and adjust the voltage of the electric power supplied to the peltier element 18, thereby automatically adjusting the temperature inside the clothes.
Fig. 10 shows a second embodiment of an air conditioning unit of the present disclosure. The same or similar components as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
In this air conditioning unit 1, an internal screw hole 50 is provided in the inner surface of the lower end portion of the housing main body 5 of the housing 2, and the blower 3 is detachably attached to the lower end of the housing 2 by screwing an external screw portion 51 provided on the upper portion of the expanded diameter blade portion 10a of the fan housing 10 of the blower 3 to the internal screw hole 50.
Therefore, the air conditioning unit 1 can be easily attached to the attached matter by inserting the portion of the fan housing 10 of the blower 3 on the air outlet side into the attachment hole (not shown) provided in the clothing such as air conditioning suit or other attached matter (not shown), and sandwiching the attached matter between the lower end of the housing main body 5 and the enlarged diameter blade portion 10a of the fan housing 10 of the blower 3, and fastening the male screw portion 51 of the fan housing 10 to the female screw hole 50 of the housing main body 5. The lower one-dot chain line shown in fig. 10 shows the pinching position E1 of the attached matter.
Further, by screwing the female screw portion 7 of the fastening ring 8 to the male screw portion 6 of the outer periphery of the male screw tube portion 5a at the upper end of the housing main body 5, the attached matter is interposed between the diameter-enlarged flange 8b of the fastening ring 8 and the diameter-enlarged flange 5d provided at the lower end of the male screw tube portion 5a of the housing main body 5, and the fastening ring 8 is fastened to the male screw tube portion 5a, whereby the air conditioning unit 1 can be easily attached to the attached matter. This is the same as the first embodiment. The upper one-dot chain line shown in fig. 10 shows the sandwiched position E2 of the attached matter. Therefore, depending on the state of the attached matter, the position of the attached matter to be interposed between E1 and E2 can be selected. In the case where the insertion position of the attached matter is E1, a duct (not shown) connected to the 1 st air passage C may be used to discharge air out of the attached matter.
In the second embodiment, the outer peripheral portion of the partition wall 14 and the outer peripheral portion of the end cover 4 are clamped and fastened between the upper end of the male screw cylindrical portion 5a of the housing main body 5 and the inward flange 8d provided at the upper end of the fastening ring 8, whereby the partition wall 14 and the end cover 4 are fixedly connected to the housing main body 5.
When the air conditioner unit 1 is attached to the attached matter by sandwiching the attached matter between the enlarged diameter flange 8b of the fastening ring 8 and the enlarged diameter flange 5d of the housing main body 5 and fastening the fastening ring 8 to the male screw tube portion 5a, it is preferable to attach a gasket (not shown) having the same thickness as the attached matter to the inner side of the inward flange 8d of the fastening ring 8.
The duct 31 is integrally formed with the air blowing guide 26, and the tip end portion of the duct 31 is fitted to the 1 st exhaust port 13 in the housing main body 5.
The duct 31 may be formed of a flexible soft synthetic resin material, and the upper end thereof may be fixedly attached to the lower surface of the air blowing guide 26 formed of a hard synthetic resin material or a metal material.
In the second embodiment, a cylindrical partition wall 52 concentric with the housing body 5 is provided on the lower surface of the partition wall 14 in the housing body 5, and a vent 32 is provided in a portion of the partition wall 14 outside the partition wall 52, whereby a 1 st air duct C is formed in the partition wall 52, in which a part of the air sent from the blower 3 is guided to the outside of the housing 2 through the conduit 31 by the thermoelectric device 17 in the 1 st chamber a, and a 2 nd air duct D is formed in which another part of the air sent from the blower 3 is guided to the outside of the end cover 4 through the space between the partition wall 52 and the housing body 5, the vent 32, the thermoelectric device 17 in the 2 nd chamber B, and the 2 nd air outlet 33 of the end cover 4.
By disposing the cylindrical partition wall 52 concentrically in the case main body 5 in this manner, the 1 st air passage C and the 2 nd air passage D are formed by dividing the air sent from the blower 3 into the inside and outside of the partition wall 52, and the thickness of the entire apparatus can be reduced, and the air sent from the blower 3 can be effectively utilized, and the heat efficiency can be improved.
The end of the partition wall 52 on the blower 3 side is cut obliquely so that the portion opposite to the duct 31 is closer to the blower 3 than the other portion.
With this configuration, since the rising dimension of the partition wall 52 from the partition wall 14 toward the blower 3 is larger than the portion facing the duct 31, the air sent from the blower 3 into the tubular partition wall 52 contacts the partition wall 14, and then enters the blower guide 26 through the air inlet 29 (see fig. 5) of the blower guide 26, and is smoothly guided to the duct 31. Therefore, the entire device can be further thinned, and the thermal efficiency can be improved.
Since other structures and functions are the same as those in the first embodiment shown in fig. 1 to 6, a detailed description thereof will be omitted. In the second embodiment, the parts corresponding to the cylinder 9 in the first embodiment are omitted.
The present disclosure is not limited to the above-described embodiments, but may be embodied in several variations without departing from the scope of the claims, for example.
(1) The outer shape of the housing 2 other than the male screw cylindrical portion 5a of the housing main body 5 and the female screw portion 7 of the fastening ring 8 is polygonal or other non-circular.
(2) The thermoelectric device 17 is one or more than three.
(3) In the second embodiment shown in fig. 10, a protrusion and a recess (not shown) for positioning in the circumferential direction are provided between the upper end of the male screw cylindrical portion 5a of the housing main body 5 and the lower surface of the partition wall 14, and between the upper surface of the partition wall 14 and the lower surface of the end cap 4, respectively.
Although the air conditioning unit has been described above, the air conditioning unit may be configured by using the general-purpose blower 3 and attaching the air conditioning module and the blower 3 of the present disclosure.
