Abstract
Description
- The present invention relates to an air-conditioning apparatus and a support system of the same. More particularly, the invention relates to an indoor unit of an air-conditioning apparatus including a remote control (in the invention, referred to as a "remote control unit") provided with an interface display and a support system of the air-conditioning apparatus including a highly functional mobile phone (smartphone).
- Hitherto, there has been many cases in which a user wonders, "Is it a malfunction?" when a situation different from normal operation is encountered or when a display not usually seen is displayed on the main body during operation of the air-conditioning apparatus. In such cases, the user is unable to immediately judge "whether it is a malfunction or whether it is not a malfunction and is a normal operating state". As such, the user makes a judgment by reading an "instruction manual" that explains how to use the air-conditioning apparatus or by viewing the "website (site on the Internet)", which is time consuming. Furthermore, it is difficult for the user to immediately check information in a case in which the user has lost the instruction manual or when the user is unable to access the website.
- Note that as regards the operation and state that causes the user to wonder, "Is it a malfunction?" of the air-conditioning apparatus, there are cases in which there is actually a malfunction in the air-conditioning apparatus leading to operation stop or abnormal operation, whereby there are cases in which although the air-conditioner seems to be operating in an abnormal way, it is not a malfunction but a normal operation (state). Further, there is a case in which the user can repair the malfunction by himself/herself when there is a malfunction and a case in which the user cannot repair the malfunction.
Accordingly, there has been demand for making the user capable of understanding (judging) "what kind of situation" the present situation is under.
Accordingly, there is disclosed a voice notification device of an air-conditioning apparatus that is capable of notifying information on the state of the air-conditioning apparatus (hereinafter, referred to as "state information") including the abnormal state, a self-diagnosis result, and the operation state of the air-conditioning apparatus by means of voice. - [Patent Literature 1] Japanese Unexamined Patent Application Publication No.
2000-81242 Fig. 3 ) - However, the voice notification device of the air-conditioning apparatus disclosed in
Patent Literature 1 has the following disadvantages: - a. Since state information is notified by voice, the voice may be drowned out by the surrounding sound or may be mixed with the surrounding sound causing a case in which the voice is unable to accurately reach the user in need of the state information, as well as the voice itself that has been notified becoming a noise to users other than the user in need of the state information, thus causing discomfort.
- b. When an error check command from the remote control is received while there is no error flag stored in the control unit, only a voice stating "No abnormality" will be produced. The user has dispatched the error check command to relieve doubts and worries caused by a situation that is rarely encountered during daily operation. Although the user will understand that there is no abnormality, ultimately, the doubts and worries will not be relieved.
-
- c. The user has dispatched the error check command from the remote control because a situation that is rarely encountered during daily operation has occurred; however, the remote control does not allow the user to designate the content (parts and situation, for example) of the doubts and worries. Accordingly, the user will be unsure if the abnormality check has been performed to the content that the user intends to know, and confidence towards the voice notification device is undermined.
- d. The user is notified by voice when operation modes are switched from automatic operation or defrosting operation, or when a cold-air-blast prevention operation is performed during heating operation. Accordingly, frequent notification of the state information becomes disturbing to the ear and becomes information of no interest to the user, thus causing discomfort.
- The invention has been made to overcome the above disadvantages and provides an air-conditioning apparatus that is capable of notifying the user of the state information of the air-conditioning apparatus in a simple and prompt manner.
- An air-conditioning apparatus of the invention includes components performing a refrigeration cycle; a body control unit controlling the components; and a remote control unit being capable of two-way communication with the body control unit, in which
the remote control unit includes a display unit that displays a predetermined projected image and a selection means to select the projected image displayed on the display unit, the projected image is provided with an inquiry menu to inquire about a state that occurs in low frequency during steady operation, and
when the inquiry menu is selected by manipulation of the selection means, a projected image explaining a content of the state is displayed subsequent to the inquiry menu on the display unit by communication between the remote control unit and the body control unit. - The air-conditioning apparatus according to the invention is provided with the inquiry menu to inquire about the state that has low frequency of occurrence during steady operation, and when the inquiry menu is selected, the projected image explaining the content of the situation is displayed by communication between the remote control unit and the body control unit; hence a user can be informed on the state of the air-conditioning apparatus surely and conveniently, in particular, the user can be promptly informed that it is not a malfunction. Accordingly, the air-conditioning apparatus is capable of promptly relieving the doubts and worries without having the user read the instruction manual or access the website, and enables comfortable use of the air-conditioning apparatus to continue.

A filter driventooth 43, which have a concave-convex pattern at even intervals, are formed on one side of thefilter frame 42 in parallel portions in the front-back direction. Further, thefilter frame 42 is formed of a flexible material and is tabular when formed; however, since it is flexible, when it is mounted in theindoor unit 100 of the air-conditioning apparatus, it can be shaped into a substantially J-shaped curve or a rollable substantially spiral-shape, when viewed from the side. - Referring to
Fig. 3 , the filter advancing and retractingdevice 50 is disposed on the upper front side (a position substantially in the middle in the top-bottom direction or in the upper portion close to the top side) of theindoor unit body 10 and includes afilter driving gear 53 that meshes with the filter driventooth 43 of thefilter 40, afilter drive shaft 52 to which thefilter driving gear 53 is fixed, and the filter advance/retraction drivingmotor box 51 that houses the drive motor (not shown) that rotatably drives thefilter drive shaft 52. Further, the filter advance/retraction drivingmotor box 51 is disposed close to the front side of theindoor unit body 10 substantially in the middle in the left-right direction.
Furthermore, one end of thefilter drive shaft 52 is rotatably supported by a bearing (not shown) that is provided in the filter advance/retraction drivingmotor box 51 and the other end of thefilter drive shaft 52 is rotatably supported by a bearing (not shown) that is provided in theindoor unit body 10. - Referring to
Figs. 4 to 6 , thefilter guide device 60 guides thefilter 40 such that the side of the filter that is on the upstream side of the air passage when thefilter 40 is advanced into the air passage becomes the downstream side when thefilter 40 is retracted (guides thefilter 40 such that the bottom side when advanced becomes the upper side when retracted).
Thefilter guide device 60 is a housing with its bottom side opened and is formed by, when viewed from the side, a substantially J-shaped guidetop plate 61 that includes a substantially liner area 61a and a substantiallyarcuate area 61b; a guidefront side plate 62 extending downwards from the front edge of the substantiallyarcuate area 61b of theguide top plate 61; a guiderear side plate 63 extending downwards from the rear edge of the substantiallyarcuate area 61b; and a pair ofguide end plates 64 that covers the end portions of the substantiallyarcuate area 61b and that are disposed in the substantiallyarcuate area 61b, the guidefront side plate 62, and the guiderear side plate 63. - Further, in each of the pair of
guide end plates 64, a surface cleaningbrush bearing 65 that slidably supports (repeats a normal rotation and a reverse rotation within a predetermined rotation angle) the corresponding one of the two ends of a surface cleaningbrush rocker shaft 73 and a mountinghole 68 in which a mountingprotrusion 75 of a dust box (equivalent to a dust chamber) 74, which forms thefilter cleaning device 70, are provided.
Furthermore, in a position corresponding to the nadir of the substantially J-shaped guidetop plate 61 when viewed from the side, dust throughholes 66 that are penetration grooves with a predetermined width are formed, and scrapingprotrusions protrusion 67") having a substantially wavy shape protruding downwards are provided on the bottom side of theguide tip plate 61 along the side edges of the dust throughholes 66 in the longitudinal direction (equivalent to the left-right direction of the indoor unit body 10) or in parallel to the side edges (with a predetermined distance from the side edges). - Additionally, when the filter advancing and retracting
device 60 is disposed in theindoor unit body 10, the upper side of theguide top plate 61 faces thefilter driving gear 53 of filter advancing and retractingdevice 50 while forming a predetermined gap therebetween. That is, one side of thefilter 40 abuts on theguide top plate 61 while the filter driventooth 43 formed on the other side are meshed with thefilter driving gear 53.
Note that thefilter 40 is detachable, and when not installed in the regular position with respect to thefilter guide device 60, a sensor (not shown) detects this and transmits the detection signal to the body control unit, which then issues a command forbidding the startup of the air-conditioning apparatus 1000. - Referring to
Fig. 1 , thefilter cleaning device 70 includes asurface cleaning brush 72 that is abuttable to the surface of thefilter 40 on the lower side that has been guided by thefilter guide device 60, a backsurface cleaning brush 71 that is abuttable to the surface of thefilter 40 on the upper side, and thedust box 74 that stores dust that has been remove from thefilter 40 therein. Note that the backsurface cleaning brush 71 may be omitted. - The
dust box 74 is a housing with a released upper side and is disposed under the surface cleaning brush 72 (equivalent to under theguide top plate 61 of the filter guide device 60). The upper end portion of the dust box is arranged in close contact with the guidefront side plate 62, the guiderear side plate 63, and the pair ofguide end plates 64 of thefilter guide device 60.
Here, since each of the mountingprotrusions 75 protruding in the left-right direction that are provided to thedust box 74 penetrate through the corresponding mountinghole 68 that is formed in theguide end plate 64, thedust box 74 does not fall off form thefilter guide device 60.
Accordingly, since thedust box 74 is in a state with a lid thereon with the substantiallyarcuate area 61b of theguide top plate 61 of thefilter guide device 60 and through the guidefront side plate 62, the guiderear side plate 63, and the pair ofguide end plates 64, dust that has dropped into thedust box 74 does not scatter to the surroundings. - The
surface cleaning brush 72 is disposed (embedded) in the surface cleaningbrush rocker shaft 73, and the surface cleaningbrush rocker shaft 73 is rotatably supported by the surface cleaningbrush bearings 65 that are disposed under the guide top plate 61 (to be exact, the substantiallyarcuate area 61b) of thefilter guide device 60. Here, thesurface cleaning brush 72 is embedded in the surface cleaningbrush rocker shaft 73 in the range of substantially 15 degrees in the circumferential direction; however, the invention is not limited to the above range and may be, preferably, in the range approximately under 90 degrees.
Further, the surface cleaningbrush rocker shaft 73 is parallel to the lowermost line of the substantiallyarcuate area 61b (to be exact, since dust through holes are formed, the imaginary lowermost line) of theguide top plate 61. - Furthermore, the surface cleaning
brush rocker shaft 73 is connected to a rocking means (not shown) and is rocked in a predetermined angular range (90 degrees in the front and back direction with respect to a vertical line, for example).
In addition, the backsurface cleaning brush 71 is disposed above theguide top plate 61 of thefilter guide device 60 and is fixed to theindoor unit box 10 with its end facing downwards.
Accordingly, when thefilter 40 slidably advances or retracts in the substantiallyarcuate area 61b, the end of thesurface cleaning brush 72 is abutted to one side of thefilter 40 while sliding in the front-back direction and the end of the backsurface cleaning brush 71 is abutted to the other side of thefilter 40 while sliding. - Accordingly, dust captured by the
filter 40 is removed with thesurface cleaning brush 72 and the backsurface cleaning brush 71 and is dropped into thedust box 74 through the dust throughhole 66.
Further, dust that is still attached to thesurface cleaning brush 72 is scraped off by the scrapingprotrusion 67 and drops into thedust box 74.
Note that thedust box 74 are detachable, and when not installed in the regular position, a sensor (not shown) detects this and transmits the detection signal to the body control unit, which then issues a command forbidding the startup of the air-conditioning apparatus 1000. - Referring to
Fig. 7 , theremote control 80 is capable of two-way communication with the body control unit. The method may be either an infrared two-way communication or a wireless two-way communication. Further, a triaxial acceleration sensor may be mounted (as for this, it will be described in detail separately).
Theremote control 80 includes an interface display unit (hereinafter, referred to as "display unit") 82, which displays a predetermined menu or a predetermined image thereon, disposed on the surface of theremote control body 81; aselection button 83 to manipulate the image displayed on thedisplay unit 82; ON/OFF button instructing a start/stop of an operation; and amode selection button 85 to select an operation mode. - The
display unit 82 is constituted by, for example, a full dot (255*160) liquid crystal display and displays characters and images (still images or moving images) described later (anything displayed is collectively referred to as "projected image" in the invention). Note that data of the above projected images (characters and images) may be pre-stored in a storage unit in theremote control 80 or may be stored in a storage unit in the body control unit and transmitted to theremote control 80 as required. - The selection button (equivalent to the selection means) 83 includes a plus button (also a cursor up button) 83a, a
menu button 83b, a minus button (also a cursor down button) 83c, and areturn button 83d that are circularly arranged in substantially equal angular intervals and a set button 8 that is arranged in the middle of the circle. The application method of each button will be described in detail separately.
The ON/OFF button 84 instructs the start or stop of the operation of the air-conditioning apparatus, and by pushing the button, switching is performed from OFF to ON or from ON to OFF.
Themode selection button 85 includes aheating selection button 85a to select a heating mode, adrying selection button 85b to select a dehumidification mode, and acooling selection button 85 to select a cooling mode. - Referring to
Fig. 7 , when the ON/OFF button is pushed and the air-conditioning apparatus is turned on, a displayed content that had been displayed on thedisplay unit 82 when the air-conditioning apparatus had been turned off previously is displayed.Fig. 7 indicates that the air-conditioning apparatus had been stopped during cooling operation when the set temperature was 27.5 degrees C and the set humidity was 50 %, and indicates that the operation will be resumed under the above conditions. Further, if the ON/OFF button is pushed to turn off the air-conditioning apparatus, the display on thedisplay unit 82 will disappear.
However, when there is a failure in a portion of the device (for example, when a temperature sensor for control is damaged) or when there is a nonconformance in which a portion of the detachable components are not installed properly (thehorizontal flaps display unit 82.
Note that although theselection button 83 is provided separately from thedisplay unit 82, the invention is not limited to this and the selection button may be provided integrally with thedisplay unit 82 by means of a touch panel. -
Figs. 8 to 14 describe the air-conditioning apparatus according toEmbodiment 1 of the invention.Figs. 8(a) and (b) are front views illustrating examples of the display unit when there is a malfunction andFig. 8(c) is a front view illustrating an example of the display unit when there is inappropriate installation.Fig. 9 is a front view illustrating an example of the display unit (procedures to remove the flaps) to solve the inappropriate installation.Fig. 10 is a front view illustrating an example of the display unit (procedures to install the flaps) to solve the inappropriate installation.Fig. 11 is a front view illustrating a menu displayed on one of the display units (the remote control).Fig. 12(a) is a front view illustrating an example of a display corresponding to the doubts and worries displayed on the display unit (the flap is in a horizontal state) of one of the display units (the remote control).Fig. 12(b) a front view illustrating an example of a display in response to the doubts and worries displayed on the display unit (water or white smoke is coming out) of one of the display units (the remote control).Fig. 13 is an organized flowchart of the flow of the display of one of the display units (the remote control).Fig. 14 is a front view illustrating an example of the display unit when there is a "content that the user wants to know".
Note that each of the drawings is schematically illustrated and the invention is not limited to the illustrated form of each drawing. -
Fig. 8 illustrates examples of the display of thedisplay unit 82 of theremote control 80 based on instructions of the body control unit in a case in which there is a malfunction or a nonconformance in a portion of the device before the operation is started, such as when the ON/OFF button is pushed and the apparatus is turned on or when theremote control 80 that is mounted with an acceleration sensor is picked up by a user and the acceleration sensor has detected that theremote control 80 has been moved, or in a case when a malfunction has occurred during a normal operation. - Referring to
Fig. 8(a) , "Failure of the temperature sensor for control Please call service center" is displayed on thedisplay unit 82. That is, since a malfunction that the user cannot deal with has occurred, it is explicitly displayed that "it is a malfunction" and "contact to the service center is required".
Here, when theset button 83d is pushed, "The address, the telephone number, fax number, and the like of the service center" is displayed on the display unit 82 (seeFig. 8(b) ). Accordingly, since the user can promptly deal with the malfunction, it will be possible to promptly resume the operation.
Note that since there are many types of malfunction, the message is changed in accordance with the content of the malfunction. Further, in order to ensure accuracy when the user contacts the service center, along with the message indicating the content of the malfunction, a malfunction code indicating the content of the malfunction may be displayed as well. Generally, when the user tries to know the meaning of the malfunction code, the user will be referring to an instruction manual; however, since the content of the malfunction is displayed as a message on thedisplay unit 82, the user does not have to refer to the instruction manual. Furthermore, by knowing the malfunction code, a richer content as compared to that displayed on thedisplay unit 82 as a message can be obtained in the service center. - In addition, when the
set button 83d is pushed, a message and a bar code (hereinafter, referred to as "QR code (registered trademark)") 89 such as "Read QR code below to display content of the malfunction" is displayed on the display unit 82 (seeFig. 8(c) ). Accordingly, the user can not only promptly deal with the malfunction but can also understand the content of the malfunction that has occurred.
That is, since aQR code 89 that stores a URL of the website for mobile phone terminals is displayed on thedisplay unit 82, by having the mobile phone read theQR code 89, the content of the malfunction that has occurred is displayed on the screen (not shown) of the mobile phone. Specifically, detailed information related to the air-conditioning apparatus that states the content in the instruction manual and that on the website is pre-registered in the above website and the malfunction code that corresponds to the content of the malfunction that the air-conditioning apparatus has determined is embedded in theQR code 89. Accordingly, the content of the malfunction that has occurred is selected from the pre-registered information and is displayed on the screen of the mobile phone.
Note that if the user does not need to know the content of the malfunction that has occurred, then the user may successively push theset button 83d to re-display the display illustrated inFig. 8(a) . - Referring to
Fig. 8(d) , "Horizontal flaps are not installed properly Please remove and reinstall the flaps" is displayed on thedisplay unit 82 when attempting to start the operation. That is, it is informed that although the air-conditioning apparatus is not operable, the situation can be dealt with by the user.
Here, when theset button 83d is pushed, procedures to resolve the inappropriate installation (a procedure for removing the flaps (seeFig. 9 ) and a procedure for installing the flaps (seeFig. 10 )) are sequentially displayed on thedisplay unit 82 by means of schematic diagrams and messages. - Referring to
Fig. 9(a) , "Push down the small flap at the back" is displayed as the first step for removing the flaps.
Referring toFig. 9(b) , a state in which "the safety stoppers are moved" is displayed as the second step for removing the flaps.
Referring toFig. 9(c) , a state in which "the small flap at the back is pulled out" is displayed as the third step for removing the flaps, and that the first step to the third step be carried out to the other flaps is displayed. - Referring to
Fig. 10(a) , a state in which "a flap is inserted" is displayed as the first step for installing the flaps.
Referring toFig. 10(b) , a state in which "the safety stoppers are surely inserted" is displayed as the second step for installing the flaps.
Referring toFig. 10(c) , "a message informing what kind of situation will occur when the flaps are not installed properly" is displayed along with a schematic diagram.
Accordingly, in a case in which the air-conditioning apparatus is not malfunctioning but is not operable, the user can understand the content and, further, can promptly and readily deal with the situation, thus it will be possible to promptly resume the operation. - Note that since there are many types of inoperable situations where it is not a malfunction (for example, the
filter 40 or thedust box 74 is not set in its regular position), the message is changed in accordance with the content thereof and the display indicating the procedure to resolve the inappropriate installation (for example, an outline for removing and installing thefilter 40 or an outline for removing and installing the dust box 74) is also changed.
Note that a "detachable component" in the invention is a general term referring to a component configured to be installable and detachable by the user, such as thedesign panel 13, thehorizontal flaps filter 40, as well as thedust box 74 when equipped with afilter cleaning device 70, collectively or individually. - Incidentally, as above, since various operations and states in which the user wonders, "Is it a malfunction?" are different from those that the user is usually accustomed to, even if it appears to be an abnormal operation or state, there are many cases in which it is not a malfunction but a normal operation or situation. Furthermore, much of the cases in which the user wonders, "Is it a malfunction?" concentrates to limited operations or states (not malfunctioning). Accordingly, the air-
conditioning apparatus 1000 allows displays as below on thedisplay unit 82 of theremote control 80 to promptly and appropriately relieve the doubts and worries of the user related to the limited operations or states. - Referring to
Fig. 11 (a) , when the user feels "there might be a malfunction", in order to relieve his/her doubt and worry, themenu button 83b in theremote control 80 is pushed. That is, when themenu button 83b is pushed during operation (in a state in which the ON/OFF button is in an on state), a plurality of menu items (for example, from first item to the sixth item) are displayed on the display unit 82 (seeFig. 11 (a) ).
Here, when theminus button 83c is pushed, the cursor displayed in the uppermost row moves down and when the cursor reaches the lowermost row and further when theminus button 83c is pushed, a new menu item (the seventh menu item) is displayed in the lowermost row and the menu items that has been displayed shifts up a row while the menu item that has been displayed in the uppermost row (the first menu item) disappears. - On the other hand, when the plus button 83a is pushed, in contrast to when the
minus button 83c was pushed, the cursor moves upwards and a new menu item is displayed in the uppermost row.
Accordingly, by further pushing themenu button 83b, the menu items from the third item to the eighth item that has been displayed before is displayed (seeFig. 11 (b) ).
Similarly, each time theminus button 83c is pushed, the menu item in the uppermost row disappears and a new menu item is displayed in the lowermost row. - Thus, by pushing the
minus button 83c or the plus button 83a, the cursor can be moved to the desired menu item (for example, the eighth item "In such a case as..." corresponds to the "inquiry menu" in the Solution to Problem) (seeFig. 11 (b) ). Here, when theset button 83e is pushed, items of the respective menu item "In such a case as..." is displayed (seeFig. 11 (c) ). In the "In such a case as..." display, two menu items, namely, "During heating operation..." and "From the outdoor unit...", are displayed while the cursor is set to either one and explain text "the content that is to be displayed on the screen next" is displayed. - Note that when the content of the doubt and worry is related to "During cooling operation" and "Indoor unit" and when the
minus button 83c is pushed, "From the outdoor unit..." is displayed on the upper row and "During cooling operation..." is displayed on the lower row on thedisplay unit 82 while the cursor is set to the lower row. When theminus button 83c is further pushed, the "During cooling operation..." is displayed on the upper row and "From the indoor unit..." is displayed on the lower row on thedisplay unit 82 while the cursor is set to the lower row (both of the above is not shown). - Referring to
Fig. 11 (c) , since the cursor is set to the "During heating operation...", "FAQ during heating operation will be displayed" is displayed, which explains the content that is to be displayed when theset button 83e is further pushed.
Referring toFig. 11 (d) , theminus button 83c has been pushed to move the cursor down from the state ofFig. 11 (c) . The cursor is set to "From the outdoor unit...", and "FAQ during related to the outdoor unit will be displayed" is displayed, which explains the content that is to be displayed when theset button 83e is further pushed. - Referring to
Fig. 12(a) , a figure and a message that are displayed on thedisplay unit 82 after theset button 83e is pushed when the cursor is set to the "During heating operation..." on thedisplay unit 82 as shown inFig. 11(c) is illustrated. That is, inFig 12(a) , "Horizontal flaps are in a horizontal state" is stated and the state is depicted in a schematic diagram.
Accordingly, if the point of doubt and worry of the user is the above, the doubt and worry of the user is relieved when the user reads "The horizontal flaps will be in a horizontal state at the start of operation, during defrosting, and when temperature has become above the set temperature It is not a malfunction" that is jointly stated. - Note that if the
horizontal flaps Fig. 12(a) , a content "During heating operation" that encounters doubts and worries the second most number of times, for example, "The filter cleaning machine is under operation because 50 hours has continuously elapsed since the heating operation. It is not a malfunction" is alternatively displayed by means of a message and a schematic diagram (not shown).
These displayed contents are preregistered in theindoor unit body 10 or theremote control 80 in a state in which the order of priority to display the content is set. Accordingly, the body control unit displays the meaningful content in line with the order of priority. That is, when thehorizontal flaps Fig. 12(a) is displayed and when the filter advancing and retractingdevice 50 has been activated, "...filter cleaning machine is under operation...It is not a malfunction" is displayed. - On the other hand, if the doubt and worry of the user are not what is displayed in
Fig. 12(a) that has been displayed in line with the order of priority, the user further pushes theset button 83e. Then, the content "During heating operation" that encounters doubts and worries the next most number of times, for example, "The filter cleaning machine is under operation because 50 hours has continuously elapsed since the heating operation. It is not a malfunction" or the like is displayed by means of a message and a schematic diagram (not shown). - Referring to
Fig. 12(b) , a figure and a message that are displayed on thedisplay unit 82 after theset button 83e is pushed when the cursor is set to the "From the outdoor unit..." on thedisplay unit 82 as shown inFig. 11 (d) is illustrated. That is, inFig 12(b) , "There is water or white smoke coming out" is stated and the state is depicted in a schematic diagram.
Accordingly, if the point of doubt and worry of the user is the above, the doubt and worry of the user is relieved when the user reads "Water and steam may come out of the outdoor unit during heating operation It is not a malfunction" that is jointly stated.
When the user further pushes the plus button 83a or theminus button 83c, "It is not a malfunction but if the wetting is causing a problem, please consult the service center for drainage work" is displayed. When the user pushes the plus button 83a or theminus button 83c again, then "Information (name, telephone number, etc.) of the service center (may include the dealer)" is displayed (not shown). - Note that if it is a situation in which water and steam could not possibly come out of the outdoor unit (for example, when during heating operation and the outdoor humidity is substantially low, or the like), then it will be meaningless to display the display in
Fig. 12(b) ; hence, similar to the above, a content encountering the next most number of doubts and worries are alternatively displayed.
Further, these displayed contents are preregistered in theindoor unit body 10 or theremote control 80 in a state in which the order of priority to display the content is set.
On the other hand, if the doubt and worry of the user are not what is displayed inFig. 12(b) , the user further pushes theset button 83e. Then, a content encountering the next most number of doubts and worries are subsequently displayed. - Note that the above operation or state that the user feels doubt and worry does not need to be displayed repeatedly once the user has understood and memorized them. Accordingly, the air-
conditioning apparatus 1000 has a function of stopping display of the contents that do not have to be displayed anymore.
That is, when theset button 83e is pushed in the state illustrated inFig. 12(a) , for example, a display "Continue to display this display?" and "Stop displaying this display?" is displayed on thedisplay unit 82. At this time, when the cursor is set to "Stop displaying this display?" by pushing the plus button 83a orminus button 83c, and theset button 83e is pushed, from then on, display illustrated inFig. 12(a) will not be displayed (both not shown). -
Fig. 13 is an organized flowchart of the above flow of the display of thedisplay unit 82. That is, in the air-conditioning apparatus 1000, when there is a malfunction or when a malfunction has occurred, without a particular inquiry by the user, the content of the malfunction is displayed (S11) and, further, the contact information and the like for the repair is displayed (S12). Accordingly, the user can promptly understand the situation and it will be possible to proceed to early repair and replacement. At this time, since theQR code 89 is displayed on thedisplay unit 83, the content of the malfunction can be displayed in further detail on the screen of the mobile phone by reading theQR code 89 into the mobile phone (S13).
Further, as for the nonconformance such as inappropriate installation that the user can deal with, the content of the nonconformance is displayed (S21) without a particular inquiry by the user and the outline to resolve the nonconformance (procedure of re-installing, etc.) is displayed (S22); hence, the user can understand the situation promptly and, furthermore, it will be possible to perform early response (re-installing, etc.). - Additionally, when the user wonders, "Is it a malfunction?" upon occurrence of an operation or state that is different from the ones the user is usually accustomed to and that is not a malfunction or nonconformance such as inappropriate installation, the user can readily understand the cause by manipulating the button of the
remote control 80; hence, doubts and worries can be relieved promptly.
At this time, among the doubts and worries that are consulted in which the user has wondered "Is it a malfunction?" to the service center, ones with higher frequency are displayed in descending-order (S32, S42); hence, the user can display the content that the user wants to know by simple manipulation of the button (S31, S41).
Further, when the doubt and worry in which the user has wondered "Is it a malfunction?" is resolved and when it is determined that it does not have to be displayed from then on (S33), the display thereof can be stopped (S34). - As above, the content of the malfunction or the content of the inappropriate installation, the resolving method, or the display relieving the doubts and worries toward various operations and states that makes the user wonder, "Is it a malfunction" are displayed on the
display unit 82 of theremote control 80 in the air-conditioning apparatus 1000.
Further, even if there is no malfunction or the like or any worries, if there is a "content that the user wants to know", the user can readily obtain the contents stated in the "instruction manual" or the "website (site on the Internet)". Accordingly, when the user has lost the instruction manual or when is unable to access the website, the user can immediately check the content that he/her wants to know and as such, convenience is improved. - Referring to
Fig. 14(a) , themenu button 83b of theremote control 80 is pushed when there is a "content the user wants to know". That is, when themenu button 83b is pushed during operation (in a state in which the ON/OFF button is in an on state), a plurality of menu items (for example, from first item to the sixth item) are displayed on the display unit 82 (equivalent toFig. 11(a) ). At this time, the cursor can be set to the "? Instruction manual" that is the desired menu item by pushing theminus button 83c or the plus button 83a (seeFig. 4(b) ).
Here, when theset button 83e is pushed, the item of the respective menu item "Read the subsequent QR code to display content of the instruction manual" is displayed. When theset button 83e is further pushed, aQR code 88 that stores a URL of the website for mobile phone terminals is displayed on the display unit 82 (seeFig. 14(d) ). - Accordingly, by having the mobile phone (not shown) read the
QR code 88, the content stated in the instruction manual is displayed on the screen of the mobile phone. That is, detailed information related to the air-conditioning apparatus that is stated in the instruction manual and the website is pre-registered in the above website.
The display "Read the subsequent QR code...(seeFig. 14(c) )" and the display "QR code 88 (seeFig. 14(d) )" may be displayed at the same time integrally on the display unit 82 (seeFig. 8(c) ). Furthermore, although theQR code 88 corresponding to the entire instruction manual is displayed, the invention is not limited to this; the user may select a segmented portion of the instruction manual (for example, "Knowing the functions", "Keeping the apparatus clean", or "Trouble shooting", etc.) and a QR code corresponding to the selected portion may be displayed. -
Figs. 15 to 18 are for explaining the support system of the air-conditioning apparatus according to Embodiment 2 of the invention,Fig. 15 is a block diagram schematically illustrating the configuration of the system, andFigs. 16 to 18 are flowcharts illustrating the operation flow. Note that like parts or equivalent parts toEmbodiment 1 are designated with like reference numerals and a portion of the description is omitted. - Referring to

screen 201 as well as displaying the "select menu" on the screen 201 (S56) to ask the user U the object of the startup of thesupport application 210. The select menu is "Read the instruction manual" and "The air-conditioner is functioning strangely", for example (S57). - Here, when the "Read the instruction manual" is selected, "Table of contents" and "Selective keyword" are displayed (S61).
Hereupon, when the User U selects the "Table of contents" (S62), the relevant selected information is transmitted from the center PC 400 (or the server 500) and the table of contents of the instruction manual is sent back to the smartphone 200 (S63).
Further, upon display of the table of contents on the screen 201 (S64), the user U selects a certain item in the table of contents (for example, "set timer" or the like) (S65) and information of the relevant item is transmitted to thecenter PC 400. The content corresponding to the relevant item in the data of the instruction manual that is stored in theserver 500 is sent back to the smartphone 200 (S66).
Then, the content of the certain item (for example, "Outline of setting the timer" or the like) is displayed on thescreen 201 in the form of still images or moving images (S67).
Further, by pushing the "End" button displayed in a corner of the screen (that is displaying the still images or moving images) (S68), thesmartphone application 210 is ended (S69). - On the other hand, when the "Selective keyword" is selected in (S61) where the "Table of contents" and "Selective keyword" are displayed, since a text box to input the "Selective keyword" is displayed on the
screen 201, the user U inputs a certain selective keyword (for example, "Before waking up" or the like) (S71). The relevant input information is transmitted to thecenter PC 400, thecenter PC 400 determines the item (for example, "timer setting" or the like) in the data of the instruction manual corresponding to the relative selected keyword, the relevant item information is transmitted to the server 500 (S72), and the content corresponding to the relevant item in the data of the instruction manual that is stored in theserver 500 is sent back to the smartphone 200 (S73).
Then, the content of the relevant item (for example, "Outline of setting the timer" or the like) is displayed on thescreen 201 in the form of still images or moving images (S74).
Further, by pushing the "End" button displayed in a corner of the screen (in which the screen is displaying the still images or moving images) (S68), thesmartphone application 210 is ended (S69). - Furthermore, when "Air-conditioner is functioning strangely" is selected in (S56), "Please take a video of the air-conditioner" is displayed on the screen 201 (S81).
Further, the video of the air-conditioner is transmitted to thecenter PC 400 and the relevant video is displayed on adisplay panel 401 of the center PC 400 (S82).
Then, a staff S (who has already been informed of the model type of the indoor unit 100) that is standing by in the support center determines the state of the air-conditioner on the basis of the relevant video, namely, whether "in a state that can be left alone", "in a state in which the user U can deal with" or "in a state in which the user U cannot deal with" (S83), and the determined result is sent back to the smart phone 200 (S84). - When it is determined to be "in a state that can be left alone", then, "Do not worry, this phenomenon will stop soon", for example, is displayed on the screen 201 (S85), thus the user U can feel relieved.
Further, when it is determined to be "in a state in which the user U can deal with", then "This Phenomenon will stop with simple manipulation. Display the manipulation guidance?", for example, is displayed on the screen 201 (S91). When the user U selects "Display" (S92), the relevant selected information is transmitted to the center PC 400 (S93), the guidance of the relevant manipulation that is stored in theserver 500 is sent back to thesmartphone 200, and a video showing the guidance of the relevant manipulation is displayed on the screen 201 (S94).
Accordingly, the user U can watch the video (or multiple still images) displayed on thescreen 201 and perform a certain manipulation, thus can recover the state of the air-conditioner to its regular state. - Furthermore, when it is determined to be "in a state in which the user U cannot deal with" in (S83) or when the user U does not select "Display" in (S92), "Service by a specialist is required", for example, is displayed on the screen 201 (S101).
At this time, when the user U selects "Request service" (S102), the request is transmitted to the center PC 400 (S103), thecenter PC 400 selects the appropriate (nearest)local service spot 600 while referring to the positional information of thesmartphone 200, and information (name, location on the map, and the like) of the relevantlocal service spot 600 is sent back to the smartphone 200 (S104). Moreover, the model type of the air-conditioning apparatus 1000, information on the status, and information on the user U is notified to the relevant local service spot 600 (S105).
Note that when the user U selects "Service not requested" in (S102), thesmartphone application 210 is ended (S69). - Accordingly, with the
support system 2000, the user U can read the content of the instruction manual, especially the content that the user wants to know the most with simple manipulation and further in the form of video without manipulation of theremote control 80. Furthermore, the user can be informed of a proper way to respond when the air-conditioner is malfunctioning. At this time, since a specialist S views the video and the diagnosis of the state of the air-conditioner is performed, a more precise judgment can be made.
