Description
Technical Field
The present invention relates to a circulator and a circulator system for stirring indoor air.
Background
The circulator fixes the blown-out air flow in the direction directly below during heating, and makes the warm air staying at the upper part of the room descend to the vicinity of the floor, thereby making the temperature distribution in the room uniform. On the other hand, in cooling, the blown air flow is moved without being fixed in one direction, so that the cooled air is efficiently diffused over a wide range, and the temperature distribution in the room is made uniform.
Therefore, the circulator used throughout the year requires a position detection function and a panning operation function in the right-down direction.
The circulator disclosed in patent document 1 inputs an output of a photo interrupter for detecting a position of a fan housing driven by a geared motor to a microcontroller in a control board, and detects the position of the fan housing. That is, in the invention disclosed in patent document 1, the blowing direction is fixed directly below by position detection using the photo interrupter.

Detailed Description
Hereinafter, a circulator and a circulator system according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.
Detailed description of the preferred embodiments
Fig. 1 is a perspective view of a circulator according to an embodiment of the present invention. Fig. 2 is a sectional view of the circulator of the embodiment. In fig. 1, the top surface of the housing 10 is not shown, and the structure inside the circulator 20 is visually shown. The circulator 20 of the embodiment includes: a rectangular parallelepiped frame 10 having an open bottom; a cross flow fan 1 which is a centrifugal fan that generates an air flow in a direction orthogonal to a rotation axis; a fan casing 2 that determines the blowing direction of the airflow generated by the cross flow fan 1; and an oscillating mechanism portion 3 that oscillates the fan casing 2 to perform an oscillating motion and changes the blowing direction. The intake airflow 4 is formed by taking in air from the gap between the frame 10 and the fan casing 2, and is blown out from the outlet 2a of the fan casing 2 as the blown airflow 5.
The circulator 20 of the embodiment is provided with a control unit 11 for controlling the oscillating motion. The control unit 11 is connected to a remote controller 12 that receives user operations. When the user operates the remote controller 12, an operation instruction is transmitted from the remote controller 12 to the control unit 11.
Fig. 3 is an enlarged view of the oscillating mechanism portion of the circulator according to the embodiment. The oscillating mechanism 3 includes: a geared motor 6 which is a driving source for oscillating movement of the fan housing 2; and a crank 9 that converts the rotational motion of the shaft of the geared motor 6 into a reciprocating motion and transmits it to the fan housing 2.
A position detection plate 7 is attached to the shaft of the geared motor 6. Further, a photo interrupter 8 is provided across the position detection plate 7. The position detection plate 7 and the photo interrupter 8 constitute a position detection unit that detects the panning stop position of the fan housing 2.
Fig. 4 is a side view of a position detecting plate of the circulator of the embodiment. The position detection plate 7 has a plurality of protrusions 71 that shield the photo interrupter 8 from light. The projection 71a, which is one of the plurality of projections 71, is wider than the other projections 71 b. Further, the width of the projection 71 refers to the dimension in the rotational direction of the position detection plate 7. Therefore, the protrusion 71a being wider than the protrusion 71b means that the size of the protrusion 71a is larger than the size of the protrusion 71b when the sizes of the position detection plate 7 in the rotation direction are compared. The protrusions 71 form a light-transmitting portion 72 that does not block light from the photo interrupter 8. By the position detection plate 7 rotating together with the shaft of the geared motor 6, the position detection unit alternately repeats a light-shielding state in which light of the photo interrupter 8 is shielded and a light-transmitting state in which light of the photo interrupter 8 is not shielded during driving of the geared motor 6. Fig. 5 is a diagram showing a waveform of an output signal of the photo interrupter of the circulator according to the embodiment. The vertical axis represents voltage, and the horizontal axis represents time. The photo interrupter 8 outputs a low-level signal when in a light transmitting state and outputs a high-level signal when in a light blocking state.
Fig. 6 is a diagram showing changes in the output signal of the photo interrupter of the circulator according to the embodiment. The vertical axis represents voltage, and the horizontal axis represents time. The projection 71a is wider than the other projections 71b, and therefore, the time for blocking the light of the photo interrupter 8 is longer than the other projections 71 b. Therefore, a period in which the protrusion 71a outputs a high-level signal when the light from the photo interrupter 8 is blocked is longer than a period in which the protrusion 71b outputs a high-level signal when the light from the photo interrupter 8 is blocked.
The control section 11 is inputted with an output signal of the optical interrupter 8. The control unit 11 detects the panning stop position when the output signal of the photo interrupter 8 falls when detecting a low level signal for X seconds or longer and then detecting a high level signal for Y seconds or longer. Here, a period T1 in which a period immediately before the projection 71b blocks the light of the photo interrupter 8 and detects a high-level signal are added together is shorter than Z seconds. On the other hand, a period T2 in which a low-level signal is detected immediately before the projection 71a blocks the light of the photo interrupter 8 and a period T when a high-level signal is detected by the projection 71a blocking the light of the photo interrupter 8 is Z seconds or more. Therefore, when the sum of the period during which the low-level signal is detected and the period during which the high-level signal is detected is Z seconds or longer, the control unit 11 can recognize that the portion of the position detection plate 7 where the protrusion 71a is provided has passed through the portion where the photointerrupter 8 is provided. In fig. 4, when the position detection plate 7 rotates in the direction indicated by the arrow a, when the portion indicated by the arrow BC passes through the portion provided with the photointerrupter 8, the sum of the period during which the low-level signal is detected and the period during which the high-level signal is detected is Z seconds or longer.
Fig. 7 is a diagram showing a configuration of a remote controller connected to the circulator of the embodiment. The remote controller 12 includes: an airflow direction changing switch 121 that outputs a command to change the blowing direction to the control unit 11 when an operation is received; a right-lower fixed switch 122 that outputs a command to change the blowing direction to the right lower direction to the control unit 11 when receiving an operation; and a display unit 123 that displays the currently set blowing direction. The display unit 123 selectively displays one of a plurality of arrows indicating different blowing directions. Each time the airflow direction changing switch 121 is operated, the direction of the arrow displayed on the display unit 123 also changes to a direction indicating the currently set blowing direction. When the direct lower fixed switch 122 is operated, the arrow displayed on the display portion 123 changes to an arrow indicating that the blowing direction is direct lower.
Fig. 8 is a diagram showing a relationship between the oscillating stop position and the blowing direction of the circulator according to the embodiment. Here, the position detection plate 7 has 12 protrusions 71 of nos. 1 to 12. The projection 71a of No.1 is wider than the projections 71b of nos. 2 to 12. The circulator 20 of the embodiment includes 7 kinds of oscillation stop positions corresponding to the respective protrusions 71 of nos. 1 to 12. The projection 71b of No.2 and the projection 71b of No.12 correspond to the same pan stop position. The corresponding head stop positions of projection 71b of No.3 and projection 71b of No.11 are the same. The corresponding head stop positions of projection 71b of No.4 and projection 71b of No.10 are the same. The corresponding pan stop positions of projection 71b of No.5 and projection 71b of No.9 are the same. The corresponding pan stop positions of projection 71b of No.6 and projection 71b of No.8 are the same.
Fig. 9 is a diagram showing a relationship between the angle of the gear motor and the blowing direction angle of the circulator according to the embodiment. The vertical axis represents the blowing direction angle, and the horizontal axis represents the angle of the geared motor. The blowing direction directly below the circulator 20 is 0 °, and if the blowing direction angle is a positive value, the airflow is blown out toward the front of the apparatus, and if the blowing direction angle is a negative value, the airflow is blown out toward the rear of the apparatus. Here, the swing motion in the direction in which the blowing direction changes from the front to the rear of the apparatus is defined as the forward movement, and the swing motion in the direction in which the blowing direction changes from the rear to the front of the apparatus is defined as the backward movement. That is, the swing motion in which the value of the blowing direction angle decreases is an outward path, and the swing motion in which the value of the blowing direction angle increases is a return path.
When a command for specifying the blowing direction is input from the remote controller 12 and the oscillating motion of the fan housing 2 is stopped at a specified oscillation stop position, the control unit 11 continues the oscillating motion without stopping the fan housing 2 at the oscillation stop position when the oscillating mechanism unit 3 moves the fan housing 2 in the direction opposite to the predetermined direction, and stops the fan housing 2 at the oscillation stop position when the oscillating mechanism unit 3 moves the fan housing 2 in the predetermined direction. In the present embodiment, the case where the oscillating mechanism portion 3 moves the fan casing 2 in the predetermined direction is an outward path, and the case where the oscillating mechanism portion 3 moves the fan casing 2 in the direction opposite to the predetermined direction is a return path.
For example, when a command for designating the blowing direction as directly below is input, if the panning operation is stopped at the panning stop position at which the projection 71b of No.4 or the projection 71b of No.10 blocks the light of the photo interrupter 8, the blowing direction is directly below. However, the control unit 11 stops the panning operation at the panning stop position at which the projection 71b of No.10 blocks the light of the photo interrupter 8, and stops the panning operation at the panning stop position at which the projection 71b of No.4 blocks the light of the photo interrupter 8. Thus, when the swing motion is restarted after the blowing direction is fixed, the swing direction after the swing motion is restarted is fixed.
In the above description, the control unit 11 stops the swing motion at the swing stop position that is the designated blowing direction during the swing motion of the outward path, but may stop the swing motion during the return path. Further, the user may be allowed to set whether to stop the oscillation motion during the forward path or to stop the oscillation motion during the backward path.
Fig. 10 is a diagram showing a configuration of a circulator system using the circulator of the embodiment. The circulator system 30 is configured by connecting a plurality of circulators 20 to the remote controller 12.
In the circulator system 30 using the circulators 20 of the embodiment, a command for designating the blowing direction is input from the remote controller 12 to the plurality of circulators 20, the oscillating operation is stopped at the same oscillating stop position, and then, when the oscillating operation is started again, the oscillating operation of the plurality of circulators 20 is performed in the same direction. Thus, the circulator system 30 using the circulators 20 of the embodiment can synchronize the oscillating motions of the plurality of circulators 20 in the oscillating motion performed after the blowing direction is fixed. Therefore, the circulator system 30 of the embodiment can prevent the blown air flow from interfering with each other and causing a reduction in the cycle efficiency.
In the above description, the projection 71a as one of the plurality of projections 71 is wider than the other projections 71b, but the position detection plate 7 is not limited to the structure described in the above embodiment as long as a specific position of the position detection plate 7 can be detected. Therefore, the width of one of the projections 71 may be narrower than the width of the other projections 71. Further, one of the light transmission portions 72 may be wider or narrower than the other light transmission portions 72. That is, at least one of the projection 71 and the light transmission portion 72 may be different in size from the other projection 71 or the other light transmission portion 72 in the rotation direction of the position detection plate 7.
The functions of the control unit 11 of the above embodiment are realized by a processing circuit. That is, the control unit 11 includes a processing circuit that performs: when the oscillating motion of the fan housing 2 is stopped at the oscillation stop position, the fan housing 2 is stopped while the oscillating mechanism 3 moves the fan housing 2 in a predetermined direction. The processing circuit may be dedicated hardware or may be an arithmetic device that executes a program stored in a storage device.
Where the processing circuitry is dedicated hardware, the processing circuitry may be a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an integrated circuit for a specific use, a field programmable gate array, or a combination thereof. Fig. 11 is a diagram showing a configuration in which the function of the control unit of the circulator according to the embodiment is realized by hardware. The processing circuit 19 is loaded with a logic circuit 19a that implements the following processing: when the oscillating motion of the fan housing 2 is stopped at the oscillation stop position, the fan housing 2 is stopped while the oscillating mechanism 3 moves the fan housing 2 in a predetermined direction.
When the processing circuit 19 is an arithmetic device, the processing for stopping the fan casing 2 while the oscillating mechanism 3 moves the fan casing 2 in a predetermined direction when the oscillating motion of the fan casing 2 is stopped at the oscillation stop position is realized by software, firmware, or a combination of software and firmware.
Fig. 12 is a diagram showing a configuration in which the function of the control unit of the circulator according to the embodiment is realized by software. The processing circuit 19 includes an arithmetic device 191 that executes the program 19b, a random access memory 192 that is used by the arithmetic device 191 in a work area, and a storage device 193 that stores the program 19 b. The arithmetic unit 191 expands the program 19b stored in the storage unit 193 onto the random access memory 192 and executes the program, thereby realizing a process of stopping the fan casing 2 while the oscillating mechanism 3 moves the fan casing 2 in a predetermined direction when the oscillating motion of the fan casing 2 is stopped at the oscillation stop position. The software or firmware is written in a programming language and stored in the storage 193. The arithmetic unit 191 may be exemplified by a central processing unit, but is not limited thereto.
The processing circuit 19 realizes each process by reading out and executing the program 19b stored in the storage device 193. That is, the circulator 20 includes the storage device 193 for storing the program 19b, and when the program 19b is executed by the processing circuit 19, the program will consequently execute the step of stopping the fan casing 2 while the oscillating mechanism 3 moves the fan casing 2 in the predetermined direction when the oscillating motion of the fan casing 2 is stopped at the oscillation stop position. The program 19b may be a program for causing a computer to execute the above-described steps and method.
Note that, when stopping the oscillating motion of the fan housing 2 at the oscillation stop position, the process of stopping the fan housing 2 while the oscillating mechanism portion 3 moves the fan housing 2 in the predetermined direction may be partly realized by dedicated hardware, and partly realized by software or firmware.
In this way, the processing circuit 19 can implement the above-described functions by hardware, software, firmware, or a combination thereof.
The configuration described in the above embodiment is an example of the contents of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or modified within a range not departing from the gist of the present invention.
