Detailed Description
FIG. 1A is a first general schematic diagram of an embodiment, and FIG. 1B is a second general schematic diagram of an embodiment; fig. 2 is a sectional view of the embodiment.
As shown in fig. 1A, 1B and 2, an air cleaning device 100 includes a frame 10 having an inlet 11 and an outlet 12, a control unit 20, and an electrostatic dust collection unit 60 disposed inside the frame 10, wherein an opening/closing curtain 40 is installed on the outlet 12 side through a rotating shaft 30, the opening angle of the opening/closing curtain 40 is controlled by the amount of air flowing to the outlet 12, the opening/closing curtain 40 is linked with the control unit 20, and the control unit 20 is triggered to control the opening/closing of the electrostatic dust collection unit 60 by the degree of the opening angle of the opening/closing curtain 40.
The air cleaning device 100 of the present invention may be used in combination with a ventilation device such as a heat exchanger or a blower, or may be used independently with an internal fan and a motor. In this embodiment, a fan is installed in a heat exchanger, and the air cleaning apparatus 100 installed on a ceiling is used in connection with the heat exchanger.
In the present embodiment, the control unit 20 is provided in the frame 10 of the air cleaning device 100, but the control unit 20 is not necessarily provided in the frame 10, and may be provided at a remote place for control.
Air is sucked from the outdoor side by the fan in the heat exchanger, and the air passes through the suction port 11 and the discharge port 12 of the air purification device 100, the air inlet and the air outlet of the heat exchanger in sequence and finally enters the indoor space.
The opening and closing curtain 40 is installed on the side of the discharge port 12 through the rotating shaft 30, and the opening angle of the opening and closing curtain 40 is controlled by the amount of air flowing to the discharge port 12, that is, the opening and closing curtain 40 can rotate around the rotating shaft 30 along with the air blown by the fan in the heat exchanger. The opening angle of the curtain 40 is the angle a between the curtain 40 and the plane of the discharge opening 12. When the fan is turned off, the curtain 40 is in a closed state (i.e. an initial state of sealing the outlet 12 of the air cleaning device 100, in this embodiment, the included angle a is 35 degrees). When the fan is started, the air volume is gradually increased, and the opening and closing curtain 40 is gradually blown away from the discharge port 12 around the rotating shaft 30. If the air volume decreases, the opening and closing curtain 40 gradually returns to the closed state.
As background art, when the heat exchanger is normally operated and the air channel is not abnormal, the larger air quantity can ensure the ozone concentration in the safe range. At this time, the curtain 40 is opened by the wind blown from the fan inside the heat exchanger, and the curtain 40 is opened by the linkage of the control unit 20 and the curtain 40, and the control unit 20 controls the electrostatic dust collecting unit 60 to start operating. Specifically, when the opening/closing curtain 40 is opened to a predetermined angle, the opening/closing of the control unit 20 is triggered, the electric circuit is completed, and the electrostatic dust collection unit 60 is started.
When abnormal conditions occur, such as the failure of a fan inside the heat exchanger or the blockage of foreign matters in an air duct, the air quantity is reduced, and the ozone concentration begins to increase. At this time, the low air volume cannot blow the opening/closing curtain 40 to such an extent that the opening/closing of the control unit 20 is triggered, the opening/closing curtain 40 is gradually closed, the electric circuit is disconnected, and the electrostatic dust collection unit 60 is closed. After the electrostatic dust collecting unit 60 is turned off, ozone is not generated any more, and the ozone concentration is maintained within a safe range.
FIG. 3 is a schematic spring diagram of an embodiment; FIG. 4 is a schematic view at the axis of rotation of the embodiment.
As shown in fig. 2-4, the shaft 30 is provided with a protrusion 31, the control unit 20 includes a micro switch 21 disposed near the shaft 30, a circuit board 22 and a circuit board box 23 surrounding the circuit board 22, when the shaft 30 rotates to a certain angle, for example, when the curtain 40 rotates with the shaft 30 to an included angle a of 45 degrees or more, the protrusion 31 presses an actuating reed 211 of the micro switch 21, the circuit of the electrostatic dust collection unit 60 is connected, and the electrostatic dust collection unit 60 operates.
When the heat exchanger normally operates and the air duct is not abnormal, the ozone concentration can be ensured within a safe range by the large air quantity. With the above structure, at this time, the opening/closing curtain 40 is blown open by the wind blown from the fan inside the heat exchanger, the rotating shaft 30 rotates to a certain angle with the opening of the opening/closing curtain 40, the protrusion 31 of the rotating shaft 30 gradually approaches and contacts and presses the actuation reed 211 of the microswitch 21 of the control unit 20, the circuit connected to the electrostatic dust collection unit 60 is conducted, and the electrostatic dust collection unit 60 is started.
The spring 50 rotating with the rotating shaft 30 is provided at the periphery of the rotating shaft 30, and when the wind power is smaller than the elastic force of the spring 50, the spring 50 drives the switch curtain 40 to rotate towards the initial position.
The initial position refers to the position of the curtain 40 when the fan is turned off (the position of the curtain 40 closing the outlet 12 of the air purification apparatus 100. in this embodiment, the included angle a between the plane of the curtain 40 and the plane of the outlet 12 is 35 degrees).
When abnormal conditions occur, such as a fan in the heat exchanger fails or a foreign object is blocked in the air duct, the air volume is reduced, the ozone concentration begins to increase, at this time, the wind power generated by the fan is smaller than the elastic force of the spring 50, the spring 50 drives the rotating shaft 30 to rotate back, the switch curtain 40 rotates to the initial position along with the rotation of the rotating shaft 30, the protruding part 31 of the rotating shaft 30 leaves the microswitch 21 of the control part 20, the circuit connected with the electrostatic dust collection unit 60 is disconnected, and the electrostatic dust collection unit 60 is closed. After the electrostatic dust collecting unit 60 is turned off, ozone is not generated any more, and the ozone concentration is maintained within a safe range. Thereby preventing the high concentration ozone from flowing into the room when the air quantity is low.
As shown in fig. 2 to 4, a mounting groove 13 for accommodating the rotating shaft 30 is formed in the frame 10, and the rotating shaft 30 can rotate in the mounting groove 13; a first end of the spring 50 is formed with a rear hook 51 to be caught on the wall of the mounting groove 13; the second end of the spring 50 forms a front hook 52 fixed in the rotation shaft 30 to rotate with the rotation shaft 30.
A spiral cylinder 53 is formed between the front hook 52 and the rear hook 51, the spiral cylinder 53 wraps the rotating shaft 30, a groove 41 is formed on the outer surface of the rotating shaft 30 along the axial direction of the rotating shaft 30, the front hook 52 is bent inward along the radial direction of the spiral cylinder 53 and then extends outward along the axial direction of the spiral cylinder 53, the front hook is inserted into the groove 41 formed on the rotating shaft 30 and fixed on the rotating shaft 30, and the rear hook 51 protrudes outward from the spiral cylinder 53.
For convenience of explanation, the embodiment of the present invention refers to the wall of the mounting groove 13 that catches the rear hook 51 as the "catching wall 131".
When the fan inside the heat exchanger is operated, wind is generated to blow the curtain 40 open, and the shaft 30 is rotated as the curtain 40 is opened. At this time, since the front hook 52 of the spring 50 is inserted into the groove 41 of the shaft 30, the rotation of the shaft 30 can rotate the front hook 52 of the spring 50, but the rear groove 51 of the spring 50 is caught by the engaging wall 131 and cannot rotate, so the spring 50 is in a state of being deformed by being forced. When the air volume is reduced and the elasticity of the spring 50 is larger than the wind power, the spring 50 is gradually restored to drive the rotating shaft 30 to rotate, the protruding part 31 of the rotating shaft 30 leaves the microswitch 21 of the control part 20, the circuit communicated with the electrostatic dust collection unit 60 is disconnected, and the electrostatic dust collection unit 60 is closed. After the electrostatic dust collecting unit 60 is turned off, ozone is not generated any more, and the ozone concentration is maintained within a safe range.
The mounting groove 13 for receiving the rotation shaft 30 is integrally formed on the circuit board case 23. Since the microswitch 21 is connected to the circuit board 22 by an electric wire, the microswitch 21 is generally disposed near the circuit board 22 and can be easily wired. Since the protrusion 31 of the rotating shaft 30 is interlocked with the microswitch 21, the rotating shaft 30 is disposed in the vicinity of the microswitch 21. Directly, the mounting groove 13 for accommodating the rotating shaft 30 is integrally formed on the circuit board box 23, so that the rotating shaft 30, the micro switch 21 and the circuit board 22 are located at adjacent positions, and compared with the mounting groove 13 additionally arranged inside the frame 10, the number of parts is reduced, the assembling steps of the air purification device 100 are also reduced, and the assembly is convenient.
A prompter (not shown) connected with the control part 20 is arranged in the room, and when the air volume is reduced, the rotating shaft 30 of the switch curtain 40 is separated from the microswitch 21, and the circuit is disconnected, the prompter gives out a prompt.
The prompt sent by the prompter can be that an indicator light is on, or a reminding sound is sent out, etc. Through the structure, after the user receives the prompt, the air purification device 100 or the heat exchanger can be checked or cleaned in time, so that the air purification device 100 or the heat exchanger can be recovered to a normal use state. Further preventing high concentration ozone from flowing into the room when the air quantity is low.
As shown in fig. 1A and 1B, the horizontal surface of the frame 10 close to the roof is a top surface 14, the horizontal surface of the frame 10 close to the indoor space is a bottom surface 15, the surface connecting the top surface 14 and the bottom surface 15 is a side surface, the side surface provided with the suction port 11 is a first side surface 16, the side surface provided with the discharge port 12 is a second side surface 17, and the side surface connecting the first side surface 16 and the second side surface 17 is a third side surface 18 and a fourth side surface 19. The point detection plate of the air cleaning device 100 is located on one of the third side 18 and the fourth side 19.
The point detection plate of the air purification device 100 is located on one of the third side 18 and the fourth side 19, rather than on the bottom surface 15 of the frame 10, so that when a user opens the point detection plate, components inside the frame 10 fall down indoors, and the user is prevented from being injured. The safety is improved.
The rotary shaft 30 of the opening and closing curtain 40 is disposed perpendicular to the top surface 14 or the bottom surface 15 of the frame 10, and the opening and closing curtain 40 rotates in a direction parallel to the top surface 14 or the bottom surface 15. Because the checkup boards are located on the third side 18 or the fourth side 19, the ceiling beside the checkup boards of the frame 10 needs to be removed to leave a checkup opening for checkup, and the user removes the checkup boards of the frame 10 in the checkup opening for daily cleaning or maintenance. However, if the air cleaning device 100 is installed with the point inspection plate located beside the wall, there is no space beside the point inspection plate as a point inspection opening. In this case, the air cleaning apparatus 100 needs to be rotated 180 degrees in a direction in which the bottom surface 15 faces upward and the top surface 14 faces downward, so that the position of the point inspection board near the wall is shifted to the opposite side of the wall. On the other hand, if the rotation shaft 30 of the opening/closing curtain 40 is disposed parallel to the top surface 14 or the bottom surface 15 of the frame 10 and the opening/closing curtain 40 is rotated in the direction perpendicular to the top surface 14 or the bottom surface 15, the opening/closing curtain 40 is opened by its own weight even without wind power after the air cleaning apparatus 100 is rotated 180 degrees in the direction in which the bottom surface 15 faces upward and the top surface 14 faces downward, and thus the effect of preventing the high concentration ozone from flowing into the room cannot be achieved.
Therefore, the rotation shaft 30 of the opening/closing curtain 40 is disposed perpendicular to the top surface 14 or the bottom surface 15 of the frame 10, and the opening/closing curtain 40 is rotated in a direction parallel to the top surface 14 or the bottom surface 15, so that the opening/closing curtain 40 is not opened or closed by gravity even if the air cleaning apparatus 100 is rotated 180 degrees in a direction in which the bottom surface 15 faces upward and the top surface 14 faces downward. The spot inspection is convenient.
The air cleaning device 100 may be used with a ventilator having a fan therein, and the control unit 20 of the air cleaning device 100 is provided with a connection terminal for cooperating with the ventilator.
With the above structure, the air cleaning device 100 and the ventilator are simultaneously opened or closed. When the ventilator is turned off (no wind state), the electrostatic dust collection unit 60 in the air cleaning device 100 is prevented from continuing to operate, so that the ozone concentration is increased and the ozone flows into the room when the ventilator is turned on next time. Further preventing high concentration ozone from flowing into the room when the air quantity is low.
Further, an air guide wall 101 is provided between the electrostatic dust collection unit 60 and the discharge port 12, and the air guide wall 101 is provided to be inclined from the edge of the electrostatic dust collection unit 60 toward the discharge port 12. Since the air passage area of the discharge port 12 is smaller than that of the electrostatic dust collection unit 60, when the air is blown from the electrostatic dust collection unit 60 to the discharge port 12, a part of the air collides with the second side surface 17, and turbulence occurs. Since the opening angle of the opening/closing curtain 40 is controlled by the amount of air flowing to the discharge port 12, the turbulent flow may cause unstable opening/closing of the opening/closing curtain 40. By providing the air guide wall 101, the air is guided to the discharge port 12 along the air guide wall 101, and the air is intensively blown to the opening/closing curtain 40 on the discharge port 12 side, so that the opening/closing of the opening/closing curtain 40 is stabilized.
