Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator which detects the presence and position of a human body and automatically turns on and off to adjust the blowing time, the direction and state of the wind.

[0002]

2. Description of the Prior Art Conventional air conditioner space ventilators or general fan ventilators typically use a set of control vanes that can be manually or automatically operated to direct in the direction of air flow. But,
The direction of air flow cannot be changed to follow the movement of the human body;
In other words, the blast direction is either fixed or moving within a span, which can cause unnecessary power consumption when no one is in that blast area, or can enjoy blast only in those areas. .. In particular, when the air conditioner or cooler / heater power is positively on, the room temperature is already on average not heated or cooled but feels sudden cooling or heating as the person in the room walks around; homogenized It takes time to produce a total room temperature, consumes energy; moreover, a person has his desired temperature or blast state ... ie constant temperature and blast intensity cannot meet their respective preferences. In order to save energy economically, it is not necessary to cool / heat the entire room; in fact, the ventilation system follows the movements of the human body and the wind with respect to the wind strength, temperature and (relative) humidity of the person's preference. As long as the air is blown, the demand is satisfied.
Even when some people are in the room, the ventilator may blow air towards each of them instead of unintentionally blowing the air at the same rate over the entire area; Turns on when enters a room and turns off automatically when a person exits. The strength of the blast that follows the movement of the human body varies depending on the preference of the person receiving the wind and the distance from the wind source to the person receiving the wind, (the wind speed reaching the position of the recipient is exactly what is required. The above actions are all automatic and meet the energy saving policy.

Moreover, the ventilation outlets of conventional air conditioners are normally open. When the air conditioner is not in use, it collects dust and insects; when the air conditioner is turned on the next time it blows out impurities and the user feels uncomfortable; Moreover, if impurities enter the heat exchanger It has a negative effect on the efficiency of the exchanger. Thereby it is necessary to close all ventilation outlets to keep the air conditioner clean and efficient while not in use.

[0004]

SUMMARY OF THE INVENTION In order to solve these problems mentioned above, the present invention is mainly to provide a ventilator capable of automatically turning on and off and changing the air blowing direction according to the position of the human body. It is a second object of the present invention to provide a ventilation device that can change the air flow direction and strength based on personal preference and the distance from the human body to the device.

A third object of the invention is that the blasting conditions (constant or variable intensity, wind temperature and humidity, direct or indirect blasting, etc.) and the duration of the blasting can be varied according to the individual requirements of the person. It is to provide a ventilation device. A fourth object of the invention is to allow the ventilation device to close all ventilation outlets while power is off to avoid dust entering the device.

A fifth object of the present invention is to provide a ventilator having a human body sensor located on a horizontally movable grill and integrally following the turning of the human body sensor to detect and measure the presence and position of the human body. A sixth object of the present invention is to ventilate the air directly toward the physical position of the human body, or to vent the air around the human body, and avoid the direct venting of air towards the human body. Is to provide.

[0007]

To achieve the above object, the ventilator of the present invention controls a wind source, a sensor unit and ON / OFF to determine the speed of the wind source, the blowing condition and the wind direction. It consists of a group of control units that change the. The sensor unit detects / measures the number and position of the human body in the ventilation area, then when the first person enters the room, turns on the wind source and associated control unit and the last person leaves the room When operating the control unit to turn them off. When the control unit is on, the air flow direction and intensity are varied based on the position of the user; the sensor unit further tracks the particular target that may cause the control unit to provide the desired ventilation. When the ventilator stops rotating, the outlet is closed to avoid dust and impurities.

[0008]

The present invention will be better understood from the following description of specific embodiments with reference to the accompanying drawings. As shown in FIG. 1, the ventilation device T of the present invention mainly controls the wind source 1, the sensor unit 3 and ON / OFF, or changes the speed of the wind source 1 and changes the blowing state and the wind direction. And the control device 2. The sensor unit 3 has a user P1,
Detect / measure if P2s are present and their position;
If the sensor unit 3 senses someone in the area, it turns on the wind source 1 and the controller 2 and sends a message (like a microcomputer) that can change the direction and intensity of the air flow based on the user's position. Send to controller 20;
(As shown in FIG. 1, a weak wind W1 is sent to the user P1 near the wind source 1 and a strong wind W2 is sent to the user P2 far from the wind source 1) and if no one is in the ventilation area, the wind is generated. Allows the source 1 and the controller 2 to be turned off. The sensor unit 3 further tracks the specific user and enables the control device 2 to supply the specific wind required by the user. For example, when two users P1 and P2 use the controller 20 to set each request of low temperature or high temperature air, the wind source 1 generates the desired air at a constant temperature and humidity, and the controller 2 Follows the users P1 and P2 and supplies a strong wind for a long time and a weak wind for a short time respectively; or the wind source 1 separately provides winds of different temperature and humidity to the users P1 and P2. The structure and function of the above device is described in detail in the examples below.

FIG. 2 shows the basic structure of the electric circuit of the embodiment of the present invention including the sensor unit 3 and the controller 20. The sensor unit 3 consists of one or several sensors 39 (only one sensor is shown in the figure) facing each sensing area; the sensors 39 are like thermoelectric infrared sensors which sense the infrared radiation Pr of the human body. Conventional techniques can be used. The output signal generates a pulse signal through the amplifier 391 and the comparator 392 check, and then the inverter 393.
(Optional) causes the controller 20 to generate an interrupt signal, and finally the wind source 1 and the controller 2 begin to perform the desired operation based on the programming of the unlisted software program.

FIG. 3 shows the structure and function of the first embodiment of the present invention. The wind generation source 1 mainly includes a fan under the control of the controller 20, and generates a proper amount of wind. Ventilation area A1,
Numerous ventilation passages 22 facing A2, A3, A4, A5, etc.
Each air passage 22 has a control valve 21 under the control of the controller 20, which can change the ventilation volume of each air passage 22. Each valve can be fully opened to supply a large amount of wind Wf, half-opened or partially opened or completely closed to supply a small amount of wind Wn. The sensor unit 3 has the same number of transducers 311, 312, 313, 314, 315, etc. as the ventilation passages 22 which may be ultrasonic, infrared or laser units. Each converter has ventilation areas A1, A2, A3, A4, A
Corresponding to each ventilation channel 22, such as 5, can thus send an encoded signal to each ventilation area. For example, in the area A2, the human body Pf
If there is a person, the signal sent from the transmitter 312 is
reflected by f and received by receiver 32, area A
It is determined by the controller 20 which can detect the user Pf and the distance Df of 2; therefore a strong wind Wf is blown. The gentle wind Wn is blown when the user Pn is within the short distance Dn of the area A4. The control device 2 controls each ventilation path 22 according to the movement of the human body. Therefore, the human body follows wherever it moves to economically perform on / off and ventilation; when no one is in the ventilation area, the controller 2 controls the wind source 1 to turn it off. The controller 20 also has a user interface that allows the user to input desired ventilation conditions such as wind speed, temperature, humidity, natural wind, simulation and direct or indirect ventilation to the user. The sensor unit 3 follows the user and enables the control device 2 to supply an appropriate wind based on a specific request. For example, when the user not shown in the area A1 uses the user interface 29 through a wired or wireless control to input a specific ventilation request, the wind source 1 and the air volume control valve 21 corresponding to the area A1 are controlled by the controller. It is moderately controlled by 20, so area A1 obtains the required ventilation. When the user moves from the area A1 to the area A2 (the receiver 32 senses that the signal from the reflective transmitter 311 disappears and the signal from the transmitter 312 is generated), the ventilation of the area A1 is stopped. Ventilation of area A2 continues. If the user's request is not to direct the user in area A2, but to ventilate closer, the controller 2 controls the ventilation that blows to areas A1 and A3 or alternatively the upper area above the user. To do.

In the natural wind simulation, the parameters are
Prints that are recorded and digitized from the natural environment
By controlling the wind source 1 and the control valve 21 in the mode
Can be achieved. Therefore, the user selects the mode and
You can enjoy the simulated natural wind. Figure 4

Aerated air 15 is obtained. Therefore, the temperature of each mixed air 15
As for humidity and air, the air 13 and 140 are controlled by the valves 21 and 231.
Change according to each flow rate Q1, Q2 passing through each ventilation path 22 below
Can be done.

FIG. 6 shows an embodiment of the present invention exemplifying the wind flow and the blowing direction controlled by the controller 2. The flow output of the wind source 1 is controlled by the ventilation passage 22 and the control valve 21. Each control valve 21 has a ventilation passage wall 22 that simultaneously swings to open / close the ventilation passage 22 as indicated by an arrow X in the figure.
It consists of two flaps 221 and 212 which are pivotally supported at 1. The air passage 22 has a fully open S1, a half open S3, a half open S3 and a certain degree of opening S4 to allow necessary air to flow into the conduit, and is fixed in a specific direction of the air passage wall 22 and the air passage. Oriented by a grill 222 which is operated.

FIG. 7 illustrates a further embodiment of the vent passage 22 of FIG. 8 is a cross-sectional view taken along the line 8-8 of FIG. In this embodiment, each conduit 22 has a shaft 224 for the passage wall 2 in addition to the passage wall 221 and a fixed grill 222 oriented in a specific direction (usually at a specific angle in the horizontal plane).
It is shown that there are several parallel movable grilles 223 pivoted at 21 and capable of directing air flow in another axial direction (eg vertical direction), as indicated by arrow Y. Another function of the movable grill 223 is that it is in the closed state 2 as shown in FIG.
When located at 23c, it may prevent dust or impurities from entering the device when the machine is stopped.

FIG. 9 shows the structure and function of the second embodiment of the present invention. In this embodiment, the same controller 20, user interface 29, wind source 1, controller 2 and sensing unit 3 are included as in the first embodiment shown in FIG. 2; Consists of two sets of parallel movable grills 25 and 26 to regulate the flow of water in two orthogonal directions (eg horizontal and vertical). The sensing unit 3, which senses the angle A of human presence and its location, enables the controller 20 to adjust the air source 1 and the controller 2 for proper air supply as shown. When the sensing unit 3 senses the users P1 and P2 at the same position of the angle A, the control device 2 blows the wind Ws in only one direction. When there are one or more persons in different directions (for example, the user P3 is in a different position), the control device 2 swings the grills 25 and 26 so that the wind flow Wr is variably directed to the range "a". To do. Besides, the grill 25
If the machine is not used, it may be in a close position 25c to avoid dust and impurities.

FIG. 10 shows a control device 2 according to the second embodiment of the present invention.
It is a modified example of. In this embodiment, different wind flow regions B1
And two (or more) sets of movable grills 251, 261 and 252 which can be independently swung to cover B2 and B2.
262 is included. As a result, the entire effective area is expanded,
Each grill set does not rock in the extended range, thus improving overall efficiency.

The air volume control valves 21 (FIGS. 3 and 4), 211 and 212 (FIG. 6), the mixed air valve 231 (FIG. 5) and the movable grill 223 (FIGS. 7 and 8) 25 and 25 of the above embodiment.
1, 252, 26, 261 and 262 (FIGS. 9 and 10) are operated by actuators (motors, solenoids, gears, screws, connecting rods, etc.) (not shown) controlled by the controller 20. The controller 20 is basically a microcomputer consisting of a software program which carries out the functions described in the above embodiments; the sensor unit 3 and each actuating device are also based on it. These actuators and microcomputers are easily obtained by conventional techniques and will not be described below.

4 or a polygonal mirror 35, including a sensor 33, such as an infrared sensor. (It can be one or two dimensional. Sensor 33 can also be implemented as a rotary scanner). For example, in the figure, a user P1 is sensed at an angle θ1 and another user P2 is sensed at an angle θ2. The controller 20 controls the rotation of the mirror 34 or 35 and also processes the signals sensed by the sensor 33. As shown in FIG. 12, the control 20 processes the signal Sd detected by comparing it with a reference signal Sr obtained from a region A of the human body where there is no human body. (It may include stationary heat sources such as machines, appliances, etc.). Controller 20
During operation, first, the reference signal Sr is stored in the memory and the non-human heat body is removed (ignored). Therefore, the signals Sd at angles θ1 and θ2 are compared with the reference signal Sr to see if there is a clear difference; if there is no clear difference, the non-human point θx is ascertained to be empty.

FIG. 13 is a view showing the external appearance of another embodiment having a human body sensor attached to a horizontally movable grill.
The ventilator of this embodiment is an automatic atmospheric controller that regulates the internal atmosphere or is part of a conventional air conditioner 100. The main engine is located between the inner space and the outer space and provides different air control including circulation of the inner air, discharges the inner air to the outer space or sucks the outer air into the inner space. The two-way communication remote control unit 290 is used to send and receive signals between the user and the main machine. Main engine 10
0 has a display unit 290 for displaying the operating state of the main machine. The human sensor 39 may be a pyroelectric infrared sensor, and is for detecting / measuring the presence of a human body in order to perform automatic on / off. On the left and right sides of the frame 8 are inward vents 9 with blades that can be opened and closed. The frame 8 has a vent hole on the back side (not shown) in the outward direction. The vent hole is provided in the inner chamber of the main engine 100 (not shown), and air is appropriately sucked, discharged, and circulated according to the opening / closing operation of the blade of the vent hole. Can be adjusted.
Its structure and operation are not claimed and need not be discussed at length in the present invention.

The internal air (return air) 15A is the main engine 1
00 ventilator through the top and side gaps of the front panel. There, the air is discharged as outlet air 25A from the outlet 250 via a filter and appropriate temperature and humidity adjustment. The outer portion of the outlet 250 is provided with a closure device 255 that can be opened and closed and closes the outlet when not in use. The outlet 250 is further provided with a direction adjusting device for adjusting the horizontal and vertical directions of the discharged air 25A. The directing device includes a set of vertically movable grills 26 (as shown in FIG. 14) that can control the vertical direction of the discharged air and a set of horizontally movable grills that can control the horizontal direction of the discharged air. A human sensor 30, which may be a narrow range pyroelectric infrared sensor, is integrally attached to the horizontally movable grill 25. The human sensor 30 follows the turning of the horizontally movable grill 25 and detects the presence and position of the human body for each turning. The signal generated in response to the detection can be used to control the direction and duration of the air emitted. Its operation is further shown in FIG.

FIG. 14 is a view for explaining the function of the sensor 30 of the embodiment shown in FIG. The user input unit 295 is
At least a mode of emitted air that includes at least one of air emitted directly toward humans and "following" movement of the human body or air emitted "around" humans. Used to receive requests. This request, after being received by the controller 20, can be used as a reference for adjusting the operation and drive of the associated fan motor 11, vertically movable grill 26, and horizontally movable grill 25. The human sensor 30 scans the ventilation area A while following the turning of the horizontally movable grill. Angle A
At 1, it detects the presence of human P1 and generates a corresponding signal, as shown in FIG. While receiving this signal, the controller 20 controls the horizontal movable grill 25 so as to stop the turning at the angle A1 for an appropriate period when the user's request for the discharging mode directly discharges to the human and follows the movement of the human body. (While the vertically movable grill 26 is adjusted in an appropriate direction), it provides the discharge airflow W1 directed to the physical position of the human P1 for an appropriate period. Then turn continues. Angle A
In 2, the human sensor 30 senses the presence of the human P2, and the controller 20 stops the horizontally movable grill 25 for an appropriate period so that the airflow W2 is emitted directly toward the human body P2. The duration of this air flow can be a constant value or can be proportionally adjusted according to the number of people in the ventilation area, for example the stoppage of each turn can be reduced while there are many people in the ventilation area. The operation of the "following" mode of air release will be further described with reference to FIG.

In the present embodiment, the number of people is calculated from the sensed signal from the average of the round trips (right scan plus left scan) or more scans. And the value of the number of people in the ventilation area can also be used to determine the demand for fresh air outside the room. FIG. 15 is a diagram illustrating a ventilation function in adjusting the release of air to the human body. At the start of scanning from left to right, the discharge air that follows the direction of the movable grill 25 moves at a certain speed (M1). While the sensor 30 (FIG. 14) detects the presence of the person P1, its movement is stopped and the airflow W11 is emitted directly toward the person P1 for a certain period (M2). Then horizontal movement continues (M
3). Until the presence of another person is detected, this action is stopped again and the airflow is ejected directly towards the second person.
Upon turning to the rightmost point, the sensor and grille scan back from right to left to continue all these movements.

Operation in the "ambient" mode of air release is described with reference to FIGS. Horizontal movable grill 2
5 (FIG. 14) detects the human P1 in the motion (M1), and the air emitted is directly directed toward the human from the direction directly around the human P1 through the motion of the vertically movable grill 26 (FIG. 14). Can be controlled to direct the air released to the upper position (M2) or the lower position (M2 ′) of the human body so that the human P1 does not receive the direct air flow W12 (or W12 ′) and recognizes the air flow by the return flow. do not do. After a suitable period, the horizontally movable grill 25 continues to turn and the human sensor 30 follows its movement (M3). While the absence of humans is detected, the vertically movable grill 26 returns to its normal position to have a horizontal airflow. Grill 25 is M4 for a further period
During this period, the generation of the airflow W14 around the human P1 is controlled to stop. Then, the motion and scanning (M5) is continued until a human is detected. While this movement reaches the rightmost point in the ventilation area, the system swivels backwards from the rightmost to the leftward scanning.

Indeed, the rotation of the fan motor 11 (FIG. 14) is controlled to achieve a "following" mode of air release and may be accompanied by the characteristics of an integral swivel of the human sensor and a horizontally movable grill. While the human sensor 30 detects the presence of a person, the controller 20 stops the pivoting of the horizontally movable grill 25 and also a large volume of emitted air (or periodic airflow velocity changes or simulated natural wind). The above is achieved by increasing the rotation of the fan motor 11 to provide After a suitable period of time, the rotation of the fan motor 11 is changed to a suitable value and the turning and scanning are continued until another person is detected.

In the "ambient" mode of discharge of air, if the ventilation area does not comprise a set of grills that direct the ventilation direction, it achieves the same effect by varying the rotational speed of the fan motor 11. While the human sensor 30 follows the turning of the horizontally movable grill 25 to detect the presence of the human body, the controller 20 adjusts the rotation speed of the fan motor 11 to change the output volume of the airflow from the original normal value. By changing to an appropriate value, the human does not sense the direction of air release, or at the same time changes the turning speed of the horizontal movable grill 25 so as to enhance indirect air release.

Although the present invention has been described with respect to particular embodiments chosen for purposes of illustration, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope and spirit of the invention.
