Detailed Description
The following describes embodiments with reference to the drawings. In the following description, terms indicating specific directions or positions (for example, terms including "upper", "lower", "side" and "end") are used as necessary, but these terms are used for easy understanding of the present invention with reference to the drawings, and the technical scope of the present invention is not limited by the meaning of these terms. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. The drawings are schematic, and the ratio of the dimensions and the like do not necessarily match reality.
As shown in fig. 1, the air conditioner of the present embodiment includes an indoor unit 1, an outdoor unit 2, and a remote controller 3.
In the indoor unit 1, as shown in fig. 2, an indoor heat exchanger 5, an indoor fan 6, a frame 7, a control unit 8 (see fig. 1), and the like are housed in a main body casing 4.
The main body casing 4 includes an internal space surrounded by a plurality of surfaces including an upper surface 9, a front surface 10, an inclined lower surface 11, and a horizontal lower surface 12, and accommodates the indoor heat exchanger 5 and the like.
The front portion 10 is formed of a front panel extending substantially in the vertical direction. The front panel is attached to the upper portion 9 so as to be rotatable about a support shaft, not shown. The front panel is rotated by driving a motor, not shown.
The upper surface portion 9 is inclined downward gradually from the rear toward the front surface portion 10 side, and an unillustrated suction port is formed therein.
As shown in fig. 3, the inclined lower surface portion 11 has a receiving recess 13 recessed upward on the lower surface. A lower edge of the inclined lower surface portion 11 forms a part of the air outlet 16, and an upper flap 14, which is one of the air direction adjusting members, is attached to the vicinity thereof so as to be rotatable about a support shaft 14 a. The upper surface of the upper baffle 14 is formed by a curved surface having the most concave central portion, and the lower surface is formed substantially flat. Although not shown, a driven gear is integrally formed at one end of the support shaft 14a of the upper flap 14. The drive gear integrated with the rotation shaft of the first motor 15 is meshed with the driven gear via a plurality of intermediate gears. Thus, when the first motor 15 is driven to rotate forward and backward, the upper baffle 14 is rotated by the gears.
The upper flap 14 is positioned by being rotated to a closed position (fig. 2) in which it is accommodated in the accommodation recess 13 to constitute a part of the lower surface of the main body case 4 and other positions (for example, a maintenance open position shown in fig. 3) and stopping the first motor 15 at each position. That is, when the first motor 15 is stopped, the rotation shaft cannot rotate, and the upper flap 14 cannot be opened manually because the plurality of gears are in a meshed state. Therefore, in the present embodiment, when the user cleans each of the flaps by manual work, the first motor 15 needs to be driven to rotate the upper flap 14, as will be described later.
Horizontal lower surface portion 12 forms air outlet 16 with inclined lower surface portion 11. A lower flap 17 is rotatably attached around a support shaft 17a near the inner edge of the blow-out port 16, which is the front end of the horizontal lower surface portion 12. The lower flapper 17 is rotated by the driving of the second motor 18, but the power transmission mechanism from the rotation shaft of the second motor 18 to the fulcrum shaft of the lower flapper 17 is performed by a driving gear, a plurality of intermediate gears, and a driven gear, which are not shown, in the same manner as the upper flapper 14. The lower baffle 17 is also positioned by rotating to a closed position (fig. 2) for closing the air outlet 16 and another position (for example, an open position for maintenance shown in fig. 3), and stopping the second motor 18 at each position. However, the maintenance open position of the lower shutter 17 is set such that the angle of rotation from the closed position is larger than that of the upper shutter 14. Here, the maintenance open position of the upper shutter 14 is set as follows. That is, the angle θ 1 formed by the horizontal plane and the straight line connecting the rotation center and the end position of the top wall 14 is set to, for example, about 18 °. The maintenance open position of the lower shutter 17 is set as follows. That is, the angle θ 2 between the horizontal plane and the straight line connecting the rotation center and the end position of the lower flapper 17 is set to, for example, about 32 °. That is, in the maintenance open position, the lower surface of the upper shutter 14 is not parallel to the upper surface of the lower shutter 17 but gradually expands toward the tip.
The indoor heat exchanger 5 is arranged in a substantially C-shape in fig. 2, and exchanges heat with air passing through the outside by flowing through the inside of the heat exchange medium. The indoor heat exchanger 5 is attached to a frame 7 described later.
The indoor fan 6 is a cross flow fan and is rotatably attached to a frame 7 described later. The indoor fan 6 is rotated by driving a motor, not shown, to suck indoor air from the suction port, exchange heat with the heat exchange medium in the indoor heat exchanger 5, and blow the air into the room from the blow-out port 16.
The frame 7 is fixed to the main body casing 4 inside the suction port, and constitutes a part of the outlet flow path extending from the indoor heat exchanger 5. The indoor heat exchanger 5 and the indoor fan 6 are fixed to a frame 7, respectively.
The control unit 8 is disposed above the inclined lower surface portion 11, and performs rotation control of the indoor fan 6, rotation control of the upper and lower flaps 14 and 17, and the like, in accordance with an operation of the remote controller 3, which is an example of an operation unit.
The outdoor unit 2 includes a compressor 19, an outdoor fan 20, an outdoor heat exchanger 21, and the like. The outdoor unit 2 has the same configuration as the conventional one, and the description thereof is omitted.
As shown in fig. 4, the remote controller 3 includes a display screen 22 and a plurality of operation buttons 23. On the display screen 22, the air-conditioning state is displayed in accordance with the operation of the operation button 23. The operation buttons 23 are constituted by various buttons (first button group 24) for performing general settings for air conditioning control. A cover 25 is provided on the lower half of the remote controller 3, and when the cover 25 is opened, various buttons (second button group 26) for performing more detailed settings, which are not used at ordinary times, are provided as shown in fig. 5. The second button group 26 includes a "menu" button 27, an "arrow" button 28, an "ok" button 29, and an "end/cancel" button 30, which function as the operation unit of the present embodiment.
Next, the operation of the air conditioner configured as described above will be described.
Since the air conditioner of the present embodiment is characterized in the operation of each component in the maintenance process, the description of the other air conditioning processes will be omitted, and only the maintenance process will be described in detail below.
(maintenance start processing by remote controller 3)
In the maintenance start processing by the remote controller 3, as shown in the flowchart of fig. 6, when the user opens the cover 25 on the lower side of the remote controller 3 and detects that the "menu" button 27 is operated (step S1), the menu mode is started and predetermined menu contents are displayed on the display screen 22 (step S2). In the menu mode, one (initial menu) of a plurality of menus (7 in this case) is displayed in the central portion of the display screen 22. Further, an upward arrow "a" is displayed on the upper side of the display screen 22, and a downward arrow is displayed on the lower side of the display screen 22
When the "end/cancel" button 30 is operated (step S3) or the next operation is not performed for a predetermined time (step S4), the menu mode is ended (step S5). When the "arrow" button 28 is operated (step S6), the menu displayed at the center is changed (step S7). The menu is displayed in only one display, and the display corresponds to the display on the small display screen 22 (the display change area 22a in which the displayed characters can be freely changed is a part of the upper side in the case of the "heating and dehumidifying" display in fig. 4) by displaying the arrows in the vertical direction.
When the "ok" button 29 is operated in a state where the menu displayed at the center is changed to the character "maintenance" shown in fig. 10 by the operation of the "arrow" button 28 in the menu mode (step S8), the display is changed from "maintenance" showing the maintenance mode to "set by pressing ok 2 seconds" showing the next operation method in fig. 11 (step S9). In this state, when the "ok" button 29 is pressed for 2 seconds or more (step S10), a maintenance signal for the maintenance process is transmitted from the remote controller 3 to the control unit 8 of the indoor unit 1 (step S11). By displaying the character "set by pressing for 2 seconds", the user can be notified what operation to perform next. Further, by continuing the pressing operation of the button for a predetermined time, the user can be made aware of the execution of the maintenance process, and the erroneous operation can be prevented. As shown in fig. 12, the display screen 22 displays "maintenance" and "release: the text of the menu "is changed to the upper and lower two-stage display (step S12). At this time, "release: the text of the menu "highlights, informing the user: when the maintenance process is currently performed and the maintenance process is released, the "menu" button 27 should be operated. While the screen is displayed, the operation of the other operation button 23 is not accepted.
(maintenance treatment in indoor Unit 1)
As shown in the flowchart of fig. 7, when the controller 8 receives the maintenance signal from the remote controller 3 (step S21), it determines whether or not at least the indoor fan 6 is stopped (step S22). When the indoor fan 6 is stopped, the process proceeds directly to step S24, and when the indoor fan 6 is not stopped, the drive of the indoor fan 6 is stopped (step S23). Here, the driving of the compressor 19 and the outdoor fan 20 is also stopped, and the air conditioning is stopped. Further, the first motor 15 and the second motor 18 are driven to rotate the upper flap 14 and the lower flap 17 once to the closed position (step S24). That is, the rotational positions of the upper and lower shutters 14 and 17 are reset. Next, the first motor 15 and the second motor 18 are driven to rotate the upper flap 14 and the lower flap 17 to the maintenance open position (step S25). Whether or not the upper and lower shutters 14 and 17 have been pivoted to the maintenance open position is performed by encoders (not shown) provided to the first motor 15 and the second motor 18, respectively. The reason for resetting the rotational positions of the upper and lower shutters 14 and 17 is to accurately measure by the encoder. If a decision is made that the top gate 14 and the bottom gate 17 have been pivoted to the maintenance open position (step S26), the driving of the first motor 15 and the second motor 18 is stopped (step S27), and the top gate 14 and the bottom gate 17 are brought into a non-pivotable state.
If the upper and lower flaps 14 and 17 are positioned at the maintenance open position, the user can wipe dew or the like adhering to the upper and lower flaps 14 and 17 with a cloth or the like. The upper baffle 14 is not parallel to the lower baffle 17, and they are positioned in a state where the distal end sides are spread apart. Therefore, the user can easily perform the cleaning operation of wiping each flapper.
When the maintenance process is released, the release process is performed as follows.
(maintenance release processing by remote controller 3)
On the display screen 22 of the remote controller 3, "maintenance" and "release" are displayed in the upper and lower two stages: the characters of the menu are highlighted, and the characters have the following characters: text of menu ". In the maintenance release process by the remote controller 3, as shown in the flowchart of fig. 8, it is determined whether or not the "menu" button 27 is operated (step S31). When the "menu" button 27 is operated, the displayed characters are changed from "maintenance release: the menu "changes to" released by pressing for a certain 2 seconds "shown in fig. 13 (step S32). In this state, when the "ok" button 29 is pressed for 2 seconds or more (step S33), a maintenance release signal for releasing the maintenance process is transmitted to the control unit 8 of the indoor unit 1 (step S34). Further, the display screen 22 is set to the off state without any display (step S35).
(maintenance releasing treatment in indoor machine 1)
As shown in the flowchart of fig. 9, when the maintenance release signal is received from the remote controller 3 (step S41), the controller 8 drives the first motor 15 and the second motor 18 to rotate the upper flap 14 and the lower flap 17 from the maintenance open position to the closed position (step S42). In this state, as described above, since all the driving portions are stopped, the air conditioner stops operating until the remote controller 3 is operated next time.
In this way, when the maintenance process is started, the air conditioning process is not started even if the other operation button 23 is operated, as long as the above-described release process is not executed even if the remote controller 3 is operated. Therefore, there is no problem that the user erroneously operates the upper and lower shutters 14 and 17 during the wiping operation, for example, the indoor fan 6 is driven and the cloth is caught.
In the case where the maintenance process is performed, if air conditioners such as "heating", "cooling", and "dehumidification" are being performed, these air conditioners are forcibly stopped, but only the indoor fan 6 may be stopped.
Further, the maintenance process can be executed even in the high temperature prevention setting. Here, the high temperature prevention means "notification mode" and "forced operation mode". The "notification mode" is a mode in which, when the indoor temperature and the indoor humidity are in a dangerous area outside the predetermined range, the start of operation or the content of the operation content is automatically notified by sound. The "forced operation mode" is a mode in which the start of operation or the change of the operation content is forcibly executed when the indoor temperature and the indoor humidity are in a dangerous area outside the predetermined range. When the maintenance process is executed in the high temperature prevention setting, the process may be returned to the high temperature prevention setting again and the display screen 22 may display the result when the maintenance process is completed.
In the case where "timer on" or "timer off" is set by the remote controller 3, if the "timer on" or "timer off" time has elapsed during the maintenance process, the execution time has elapsed, but a signal for starting or stopping the operation of the air conditioner may not be transmitted.
The air conditioner of the present invention is not limited to the configuration described in the above embodiment, and various modifications are possible.
In the above embodiment, the operation unit is configured by various buttons provided on the remote controller 3, but the operation unit may be provided directly on the outdoor unit 2. In this case, the operation portion may be provided at a portion exposed by rotating the front panel. Since the operation unit provided at this position is not normally operated, it is not necessary to perform a complicated button operation as in the case of the remote controller 3. Therefore, the maintenance button and the release button for releasing the maintenance button may be used, or the maintenance button may be used to open and close the device. Note that, when the maintenance processing is started by such a button, the operation of the remote controller 3 is not accepted at all, which is similar to the above-described embodiment.
In the above embodiment, the start and release of the maintenance process are performed by pressing the "ok" button 29 for 2 seconds or more, but the time can be freely set. Further, it is also possible to operate the "ok" button 29 a plurality of times. Mainly, the user may perform an operation (irregular operation) that is not normally performed by the remote controller 3.
