Description

<DP=1>²Ventilating Device²BACKGROUND OF THE INVENTION ² Field of the Invention ²The present disclosure relates to a ventilating device and more particularly ²to a ventilating²device with a temperature / humidity sensor.² Description of the Related Art ²Fig.1 is a schematic diagram of a connection between a sensor and a circuit ²board box in a ²ventilating device in a related art. As shown in Fig.1, in the ventilating ²device 10 of the related ²art, in order to more accurately detect temperature or humidity of air ²entering from an air inlet, a ²sensor 1 that senses the temperature or humidity is provided at a place ²proximate to the air inlet.²However, since the sensor 1 needs to be connected with the circuit board so as ²to be controlled ²and be powered by the same, in the related art, a circuit board (not shown) ²with a terminal (not ²shown) is provided in a circuit board box 2, and a lead 3 is used to connect ²the sensor 1 to a ²terminal.²However, since the circuit board and the sensor 1 are connected via the lead ²3, when the²sensor needs maintenance, the lead 3 connected to the circuit board should be ²removed before ²removing the sensor 1 from a frame 4. Similarly, when the circuit board needs ²maintenance, the ²lead 3 connected to the sensor 1 should be removed before removing the circuit ²board box 2 ²provided with the circuit board. That is, work or operation may not be ²performed conveniently ²before the maintenance is actually performed.² SUMMARY OF THE INVENTION ²(I) Technical problems to be solved²As described above, the ventilating device, the sensor, or the circuit board ²box in the related²art is laborious to install and remove such that it has a low convenience in ²the maintenance or²replacement thereof.²In order to solve the above problems, the present disclosure provides a ²ventilating device ²that may use less components, facilitate assembly and disassembly of ²components, and improve ²convenience in maintenance.²(II) Technical solution²The present disclosure provides a ventilating device, comprising: a frame ²formed with an²external profile; an air inlet provided in the frame; an air outlet provided ²in the frame; an air²CA 3010809 2018-07-06²<DP=2>²blower for guiding air from the air inlet to the air outlet; a control circuit ²board connected to the ²air blower and configured to control operation of the air blower; and a ²circuit board box for ²housing the control circuit board; wherein the circuit board box comprises an ²integrally formed ²sensor storage unit for storing a sensor connected to the control circuit ²board and capable of² sensing humidity or temperature.²In an embodiment of the present disclosure, the ventilating device further ²comprises a ²terminal connected to the air blower and provided on the control circuit ²board, the control circuit ²board and a lead of the air blower being connected to each other through the ²terminal; and an ²operation opening provided in the circuit board box and opposite to the ²terminal.²In an embodiment of the present disclosure, the ventilating device further ²comprises a cover²for covering the operation opening; and an insertion opening for guiding the ²lead to the circuit ²board box.²In an embodiment of the present disclosure, the air blower comprises: a motor; ²a first air ²suction port provided proximate to the motor; a second air suction port ²opposite to the first air²suction port; an air discharge port for discharging air from the air blower; ²and a fan configured to²guide air from the first air suction port and the second air suction port into ²the air blower and ²discharge the air from the air blower via the air discharge port ²simultaneously.²In an embodiment of the present disclosure, the frame comprises: a first side ²surface ²provided with the air inlet; a second side surface opposite to the first side ²surface and provided²with the air outlet corresponding to the air discharge port; a top surface ²adjacent to the first side²surface and facing the first air suction port; a bottom face adjacent to the ²first side surface and ²facing the second air suction port; and a third side surface and a fourth side ²surface that are ²adjacent to the top surface and the bottom surface, respectively; wherein, the ²circuit board box is ²provided between the third side surface and the air blower or between the ²fourth side surface and²the air blower.²In an embodiment of the present disclosure, the ventilating device further ²comprises a first ²air path for communicating the air inlet with the first air suction port; and ²a second air path for ²communicating the air inlet with the second air suction port; wherein a ²distance from the first air ²suction port to the top surface is greater than a distance from the second air ²suction port to the²bottom surface, and the sensor storage unit is provided at a second air path ²side.²In an embodiment of the present disclosure, the sensor storage unit is ²provided with an air²entrance port provided in a face of the sensor storage unit facing the air ²inlet and configured to²guide the air into the sensor storage unit.²In an embodiment of the present disclosure, a first end of the sensor storage ²unit is provided²on a wall of the circuit board box, and a second end of the sensor storage ²unit extends outwards²from the circuit board box.²In an embodiment of the present disclosure, the air entrance port is provided ²at the second²2²CA 3010809 2018-07-06²<DP=3>²end.²(III) Benefits²As can be seen from the above technical solution, the ventilating device of ²the present² disclosure has at least one of the following beneficial effects:²(1) The circuit board box and the sensor storage unit are integrally formed ²into one piece. ²When the sensor or the control circuit board needs to be maintained or ²removed, by only ²removing the circuit board box integrally molded with the sensor storage unit, ²the sensor or the ²control circuit board may be maintained or replaced as required without being ²assembled or²disassembled separately, thereby easing their replacements and reducing labor-²hours. At the²same time, only one mold may be used to create the sensing unit and the ²circuit board box, ²which can save the mold cost. It can be seen that with such a design, it can ²simultaneously ²achieve the effects of easy assembly and disassembly of the components, ²improving the ²convenience of maintenance and saving cost.²(2) The circuit board box is disposed in a space between the third side ²surface and the air²blower, or a space between the fourth side surface and the air blower, that ²is, the circuit board ²box is disposed in a space with a small air flow, and the effect of the ²circuit board box upon the ²air flow may be minimized, so that the circuit board box may be provided ²without affecting an ²air volume.²(3) In order to facilitate maintenance of the circuit board box, an operation ²opening is²provided at a position opposite to the terminal provided on the control ²circuit board, and the lead ²connected with the air blower can be freely attached to or detached from the ²control circuit board ²through the operation opening.²When it is necessary to remove the circuit board box, as long as the cover ²covered on the²operation opening is opened, the terminal connected with the lead will be ²exposed, and the²maintenance personnel may remove the lead from the terminal through the ²operation opening. In ²this way, the circuit board box is no longer connected to the air blower, and ²the maintenance ²personnel may entirely remove the circuit board box from the frame. In ²addition, the lead may be ²inserted into the circuit board box through the insertion opening provided on ²the wall of the²circuit board box, and the lead may be fixed on the insertion opening by ²pressing the cover on an²opened portion of a notch, thereby facilitating assembly and maintenance.²(4) The distance Li from the first air suction port to the top surface is ²greater than the ²distance L2 from the second air suction port to the bottom surface. With such ²a design, the ²sensor storage unit is provided in the second air path.²When the motor is disposed at the first air suction port side, and the ²distance from the first²air suction port to the top surface is greater than the distance from the ²second air suction port to ²the bottom surface, the amount of air entering the air blower from the first ²air suction port is less²3²CA 3010809 2018-07-06²<DP=4>²than that entering the air blower from the second air suction port, that is, ²the air volume flowing ²through the first air path is less than the air volume flowing through the ²second air path. In ²addition, since the motor is disposed in the first air path, the resistance of ²the first air path is ²relatively larger and the turbulence is relatively more. Since the air volume ²flowing through the²second air path is more and the turbulence is relatively less, the sensor ²storage unit is disposed in²the second air path, so that the humidity and the temperature may be correctly ²sensed, thereby ²improving the accuracy of the temperature and humidity sensed by the sensor ²storage unit.²(5) The first end of the sensor storage unit is disposed on the wall of the ²circuit board box, ²and the second end extends outwards from the circuit board box, and the air ²entrance port is²disposed at the second end. With the above structure, the air entering the ²frame from the air inlet²flows directly to the air entrance port opposite to the air inlet. The ²humidity and temperature of ²the air entering the frame may be more quickly and accurately detected by the ²sensor provided in ²the sensor storage unit. In addition, the air entrance port is provided on the ²second end of the ²sensor storage unit extending outwards from the circuit board box. In this ²way, the second end is²closer to the air blower or the air inlet side, and more air enters the sensor ²storage unit. Therefore,²although the circuit board box is provided in a space with a small air flow, ²the sensor may ²accurately detect the humidity and temperature of the air entering the frame, ²ensuring the ²accuracy of the temperature and humidity sensed by the sensor.² BRIEF DESCRIPTION OF THE DRAWINGS ²Fig.1 is a schematic diagram of a connection between a sensor and a circuit ²board box in a ²ventilating device in the related art.²Fig.2 is a schematic structural view of a ventilating device with a bottom ²surface removed ²according to an embodiment of the present disclosure.²Fig.3 is a schematic diagram of the ventilating device shown in Fig.2 with a ²top surface and²a filter unit removed and viewed from the top surface side.²Fig.4 is a side sectional view of the ventilating device shown in Fig.2.²Fig.5A is a schematic structural diagram of a circuit board box in the ²ventilating device²shown in Fig.2.²Fig.5B is a schematic view of the circuit board box shown in Fig.5A with a ²cover removed²and viewed from another angle.²Fig.6A is a schematic diagram of an air blower, a circuit board box, and a ²sensor storage²unit in the ventilating device shown in Fig.2.²Fig.6B is an enlarged view of the sensor storage unit of Fig.6A.²Fig.7 is an internal schematic diagram of the sensor storage unit in the ²ventilating device²shown in Fig.2.²4²CA 3010809 2018-07-06²<DP=5>²Description of Main Components of Embodiments of the Present Disclosure in the²Drawings²100-frame;²111-top surface; 112-first side surface;² 113-second side surface;²114-third side surface; 115-fourth side surface; 116-bottom surface;²A-air inlet; B-air outlet;²200-air blower; 210-motor;²220-fan; 230-casing;²231-first air suction port; 232-second air suction port; 234-air discharge ²port;²L I- distance from first air suction port to top surface111;²L2- distance from second air suction port to bottom surface116;²300-first air path; 400-second air path;²600-filter unit;² 610-filter screen; 620-filter screen frame;²700-circuit board box;²711-operation opening; 711'-cover;²712-insertion opening;²720-control circuit board; 721-terminal;²722-lead;²800-sensor storage unit²811-air entrance port; 812-air exit port;²815- lid;²813- first end of sensor storage unit;²814- second end of sensor storage unit;²820-sensor; 822-sensor circuit board.²DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE IVENTION ²The present disclosure provides a ventilating device that can use less ²components, facilitate²assembly and disassembly of components, and improve maintenance convenience by ²reasonably²setting the positions of the circuit board box and the sensor storage unit.²To make the purpose, technical solutions, and advantages of the present ²application clearer, ²the following further describes the present disclosure in detail with ²reference to specific ²embodiments and the accompanying drawings.²In an exemplary embodiment of the present disclosure, a ventilating device is ²provided.²Fig.2 is a schematic structural view of a ventilating device with a bottom ²surface removed ²according to an embodiment of the present disclosure. Fig.3 is a schematic ²diagram of the²5²CA 3010809 2018-07-06²<DP=6>²,²ventilating device shown in Fig.2 viewed from the top surface side with a top ²surface and a filter ²unit removed. As shown in Fig.2, the ventilating device in this embodiment ²includes a frame 100, ²an air blower 200, a sensor 820, a filter unit 600, a circuit board box 700, ²and a sensor storage ²unit 800. Among them, the circuit board box 700 and the sensor storage unit ²800 are integrally²molded into one piece. Among them, the circuit board box 700 is configured to ²store the control²circuit board 720. The sensor storage unit 800 is configured to store a sensor ²820 connected to ²the control circuit board 700 and capable of sensing humidity or temperature.²With the above configuration, when the sensor or the control circuit board ²needs to be ²maintained or removed, by only removing the circuit board box 700 integrally ²molded with the²sensor storage unit 800, the sensor 800 or the control circuit board 720 then ²may be maintained²or replaced as required without being assembled or disassembled separately, ²thereby easing their ²replacements and reducing labor-hours. At the same time, only one mold may be ²used to create ²the sensing unit and the circuit board box, which can save the mold cost. Due ²to easy assembly ²and disassembly of the components and the convenient maintenance, it may ²achieve the effect of² saving cost.²The various components of the ventilating device in the present embodiment ²will be²described in detail with reference to the accompanying drawings.²Refereeing to Figs. 2 and 3, the frame 100 is of a hollow rectangular ²parallelepiped shape,²including a top surface 111, a bottom surface 116 facing the top surface 111, ²and four side²surfaces adjacent to the bottom surface 116 and the top surface 111, which are ²a first side surface²112, a second side surface 113, a third side surface 114 and a fourth side ²surface 115. The first ²side surface 112 and the second side surface 113 are opposite to each other, ²and the third side ²surface 114 and the fourth side surface 115 are opposite to each other.²The frame 100 is provide with an air inlet A that allows air to enter the ²frame 100 and an air²outlet B that allow the air to be discharged from the frame 100. For example, ²when the²ventilating device is set on a ceiling, the air inlet A is disposed at the ²first side surface 112; and ²the air outlet B is disposed at the second side surface 113 opposite to the ²first side surface 112 ²provided with the air inlet A.²As shown in Fig.2, the filter unit 600 has a three-dimensional rectangular ²shape, and is²provided on an upstream side of the air blower 200. The filter unit 600 ²includes a filter screen²610 and a filter screen frame 620, and may purify the air sucked from the air ²inlet A and block ²the entry of dust and fine particles.²Among them, the filter screen frame 620 has a three-dimensional rectangular ²parallelepiped ²shape for fixing the filter screen 610. The filter screen 610 is installed in ²the filter screen frame²620 and includes a filter screen achieving one or more filter effects or a ²plurality of filter screens²each achieving one or more filter effects, Such as dust filter screen, ²deodorizing filter screen, or ²dust and deodorizing filter screen.²6²CA 3010809 2018-07-06²<DP=7>²Referring to Fig.3, the air blower 200 includes: a motor 210, a fan 220, and a ²casing 230, ²wherein after the motor 210 is energized, a rotary shaft is driven to rotate. ²The fan 220 is ²connected to the rotary shaft so as to generate an air flow via the rotation ²of the fan 220 driven ²by the rotary shaft of the motor 210. The fan 220 and the motor 210 are ²contained in the casing.²The casing 230 has an air suction port and an air discharge port, and in this ²casing 230, a wind²flow from the air suction port to the air discharge port is generated due to ²the rotation of the fan ²220.²Fig.4 is a side sectional view of the ventilating device shown in Fig. 2. As ²shown in Fig.4, ²in the air blower 200, the air suction port is an opening that draws the air ²from the frame 100 into²the casing 230. The casing 230 includes a first air suction port 231 and a ²second air suction port²232 acting as air suction ports, and an air discharge port that allows air to ²be discharged from the ²air blower 200. Among them, the first air suction port 231 and the second air ²suction port 232 ²provided on the casing 230 are opposite to each other. Under the action of the ²fan 220, air enters ²the air blower 200 from the first air suction port 231 and the second air ²suction port 232, and² then is discharged from the air blower 200 via the air discharge port.²The first air suction port 231 is located at the motor 210 side of the casing ²230 and faces the ²top surface 111. The air is sucked into the casing 230 from the back side of ²the casing 230, that is, ²from the top surface of the casing 230. The second air suction port 232 is ²opposed to the first air ²suction port 231. The air is sucked into the casing 230 from the front side of ²the casing 230, that²is, from the bottom surface of the casing 230.²In particular, it should be noted that the distance from the first air suction ²port 231 to the top ²surface 111 of the frame 100 is greater than the distance from the second air ²suction port 232 to ²the bottom surface 116, which will be related to the setting position of the ²sensor storage unit in ²the present embodiment.²Referring to Fig.4 continuously, the ventilating device in this embodiment ²further includes a²first air path 300 and a second air path 400. The first air path 300 ²communicates the air inlet A ²with the first air suction port 231, that is, after the air is introduced from ²the air inlet A, it flows ²along the air path towards the first air suction port 231. The second air path ²400 communicates ²the air inlet A with the second air suction port 232, that is, after the air ²is introduced from the air².. inlet A, it flows along the air path towards the second air suction port ²232.²Referring to Figs.2, 3 and 4, the circuit board box 700 is disposed inside the ²frame 100 and ²is adjacent to the outer side of the casing 230. A control circuit board 720 ²is disposed therein. For ²example, the circuit board box 700 is disposed between the third side surface ²114 of the frame ²and the air blower 200 or between the fourth side surface 115 of the frame and ²the air blower²200.²When the ventilating device is activated, the air enters the frame 100 through ²the air inlet A,²and then enters the air blower 200 through the first air suction port 231 and ²the second air²7²CA 3010809 2018-07-06²<DP=8>²suction port 232, respectively, and then reaches the air outlet B through the ²air discharge port ²234 and is discharged from the frame 100 via the air outlet B.²After the air enters the space between the air inlet A and the air blower 200 ²from the air ²inlet A, most of the air flows directly to the first air suction port 231 and ²the second air suction²port 232. That is, most of the air flows through the space between the top ²surface 111 and the²first air suction port 231 and the space between the bottom surface 116 and ²the second air suction ²port 232, only a small amount of the air flows through the space between the ²third side surface ²114 and the air blower 200 or the space between the fourth side surface 115 ²and the air blower ²200.²Therefore, the circuit board box 700 is disposed in the space between the ²third side surface²114 and the air blower 200, or the space between the fourth side surface 115 ²and the air blower ²200, that is, the circuit board box 700 is disposed in a space with a small ²air flow. The effect of ²the circuit board box 700 upon the air flowing through the above space may be ²minimized, so ²that the circuit board box may be provided without affecting the air volume.²Fig. 5A is a schematic structural diagram of a circuit board box in the ²ventilating device²shown in Fig. 2. Fig. 5B is a schematic view of the circuit board box shown in ²Fig.5A with the ²cover removed and viewed from another angle.²As shown in Figs. 5A, 5B and Fig.3, the circuit board box 700 is provided with ²an operation²opening 711 and an insertion opening 712. The control circuit board 720 is ²provided with a² terminal 721.²The terminal 721 is connected to the air blower 200 through a terminal lead ²722. After ²receiving an electrical signal, the control circuit board 720 controls the ²operation of the air ²blower 200 through the lead 722. The terminal 721 serves as a medium for ²connecting the lead ²722 to the control circuit board 720.²The operation opening 711 is provided as an opening on a position opposite to ²the terminal²721 so that there is enough open area for the maintenance personnel to unplug ²or install the lead. ²The operation opening 711 is provided with a cover 711'.²In order to prevent dust from entering the operation opening 711, the cover ²711' is fixed to ²the circuit board box 700 by the screw and latch structure so as to cover the ²operation opening² 711.²The insertion opening 712 is an opening for allowing the lead 722 to be ²inserted into the ²circuit board box 700, and is disposed in form of a notch on the wall of the ²circuit board box 700 ²adjacent to the operation opening 711. After the lead is inserted into the ²notch, the lead 722 may ²be fixed on the insertion opening 712 by pressing the cover 711' on an opened ²portion of the²notch.²The lead 722 may not only be a wire connecting the circuit board box 700 and ²the air²blower 200, but also may be a wire that provides power for the control circuit ²board 720 and the²8²CA 3010809 2018-07-06²<DP=9>²,²operation of the air blower 200.²In this embodiment, In order to facilitate maintenance of the circuit board ²box, the operation ²opening 711 is provided at a position opposite to the terminal 721 provided on ²the control circuit ²board, and the lead 722 connected with the air blower can be freely attached ²to or detached from² the control circuit board 720 through the operation opening 711.²When it is necessary to remove the circuit board box 700, as long as the cover ²711' covered ²on the operation opening 711 is opened, the terminal 721 connected with the ²lead will be ²exposed, and the maintenance personnel may remove the lead from the terminal ²721 through ²operation opening 711. In this way, the circuit board box 700 is no longer ²connected to the air²blower 200, and the maintenance personnel may entirely remove the circuit ²board box 700 from²the frame 100. In addition, the lead 722 may be inserted into the circuit ²board box 700 through ²the insertion opening 712 provided on the wall of the circuit board box 700, ²and the lead 722 ²may be fixed on the insertion opening 712 by pressing the cover 711' on the ²opened portion of ²the notch, thereby facilitating assembly and maintenance.²Fig.6A is a schematic diagram of the air blower, the circuit board box, and ²the sensor²storage unit in the ventilating device shown in Fig.2. Fig.6B is an enlarged ²view of the sensor ²storage unit of Fig.6A. As shown in Figs. 6A and 6B, the sensor storage unit ²800 is formed ²outside the circuit board box 700, and is integrally molded into one piece ²with the circuit board ²box 700, and houses the sensor 820 and the sensor circuit board 822 therein. ²The sensor storage²unit is covered by a lid 815.²As described above, the distance Li from the first air suction port 231 to the ²top surface 111²is greater than the distance L2 from the second air suction port 232 to the ²bottom surface 116.²With such a design, the sensor storage unit is provided in the second air path ²400.²When the motor is disposed at the first air suction port 231 side, and the ²distance Li from²the first air suction port 231 to the top surface is greater than the distance ²L2 from the second air²suction port 232 to the bottom surface, the amount of air entering the air ²blower from the first air ²suction port 231 is less than that entering the air blower from the second air ²suction port 232, ²that is, the air volume flowing through the first air path 300 is less than ²the air volume flowing ²through the second air path 400. In addition, since the motor is disposed in ²the first air path 300,²the resistance of the first air path 300 is relatively larger and the ²turbulence is relatively more.²Since the air volume flowing through the second air path 400 is more and the ²turbulence is ²relatively less, the sensor storage unit is disposed in the second air path, ²so that the humidity and ²the temperature may be correctly sensed, thereby improving the accuracy of the ²temperature and ²humidity sensed by the sensor storage unit²Fig.7 is an internal schematic diagram of the sensor storage unit in the ²ventilating device²shown in Fig.2. As shown in Fig.7, the sensor 820 is stored inside the sensor ²storage unit 800 and ²is connected with the sensor circuit board 822. The sensor 820 detects the ²humidity or / and the²9²CA 3010809 2018-07-06²<DP=10>²temperature of the air passing through the sensor storage unit.²The lid 815 is a cover that covers the sensor 820 and the sensor circuit board ²822 stored in ²the sensor storage unit and constitutes a cap for a sensor storage unit. The ²sensor circuit board ²822 is housed inside the sensor storage unit and controls the sensor 820.²Wherein, please refer to Fig.7, the sensor storage unit 800 includes an air ²entrance port 811²and an air exit port 812. The air entrance port 811 is provided on the lid 815 ²of the sensor storage ²unit, that is, on a surface of the sensor storage unit 800 facing the air ²inlet A, and is an opening ²provided for allowing the air from the frame to enter the sensor storage unit. ²The air exit port 812 ²is an opening provided on the sensor storage unit and configured to allow the ²air to be discharged² from the sensor storage unit 800.²It should be noted that the first end 813 of the sensor storage unit is ²disposed on the wall ²of the circuit board box, and the second end 814 of the sensor storage unit ²extends outwards ²from the circuit board box, and the air entrance port 811 is disposed at the ²second end 814. With ²the above structure, the air entering the frame 100 from the air inlet A flows ²directly to the air²entrance port 811 opposite to the air inlet A. The humidity and temperature of ²the air entering the²frame 100 may be more quickly and accurately detected by the sensor 820 ²provided in the sensor ²storage unit. In addition, the air entrance port 811 is provided on the second ²end 814 of the ²sensor storage unit 800 extending outwards from the circuit board box. In this ²way, the second ²end 814 is closer to the air blower or the air inlet side, and more air enters ²the sensor storage unit²800. Therefore, although the circuit board box is provided in a space with a ²small air flow, the²sensor 820 may accurately detect the humidity and temperature of the air ²entering the frame 100, ²ensuring the accuracy of the temperature and humidity sensed by the sensor²Heretofore, the embodiments of the present disclosure have been described in ²detail with ²reference to the accompanying drawings.
