Description

  The present invention relates to a bathroom ventilation drying and heating system for performing ventilation, drying, and heating of a bathroom.

  When installing a bathroom ventilation drying and heating system equipped with a device main body that is fitted into a wall or ceiling of a bathroom and a remote controller that functions as an input device of the device main body, without removing the device main body from the installation location In many cases, inspection ports are provided in parallel on the wall or ceiling so that inspection and repair can be performed, but sufficient maintenance space may not be secured around the inspection port and its surroundings. For this reason, the maintenance work of the apparatus main body is relatively difficult to perform even when the inspection port is provided as well as when the inspection port is not provided. In some cases, the necessity of maintenance cannot be determined without looking inside the apparatus main body. In such a case, it takes time to disassemble and reassemble the apparatus main body, resulting in high maintenance costs.

  For example, as in the gas clothes dryer described in Patent Document 1, a measuring unit that measures aged information on a predetermined member, and a warning when the value of the aged information measured by the measuring unit exceeds a predetermined value If the warning means to be issued is provided in the bathroom ventilation drying / heating system, the maintenance staff can easily grasp the place where the maintenance is desired, so that the maintenance work is facilitated.

  In addition, as in the remote management system described in Patent Document 2, a device that detects trouble and transmits trouble data, and first information related to maintenance determined according to the type of trouble and things required for past maintenance Even if the bathroom ventilation / drying / heating system is provided with a means for displaying the second information about the maintenance, the maintenance work can be easily performed.

  Furthermore, as in the automatic test run monitoring device described in Patent Document 3, even if the function of displaying the execution result of the program at that time on the monitor and performing the automatic test run at the time of failure repair is provided in the bathroom ventilation drying heating system, It becomes easy to perform maintenance work.

Japanese Patent Laid-Open No. 7-80197 JP-A-8-317072 JP 2001-241690 A

  However, even if the above-described means or function in the devices described in Patent Documents 1 to 3 are given to the bathroom ventilation drying and heating system, the means or function is present when the value of aged information exceeds a predetermined value. Since a warning or predetermined information is displayed for the first time when a trouble or failure occurs, a quick maintenance service may not be available depending on the time zone during which the warning or predetermined information is displayed. For example, even if a regular maintenance contract is concluded, a trouble or failure may occur immediately after the maintenance staff visits, even though no warning or predetermined information is displayed. When this happens, trust in the product and maintenance service is impaired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to obtain a bathroom ventilation drying / heating system that facilitates efficient maintenance and improves the reliability of maintenance.

  The bathroom ventilation drying and heating system according to the present invention that achieves the above object includes a ventilation unit that ventilates the bathroom, a heat source unit that heats the atmosphere of the bathroom, and an apparatus main body that includes an air blowing unit that creates an airflow in a predetermined direction. A remote controller that is arranged apart from the apparatus main body and functions as an input device of the apparatus main body and also functions as a display device, and a storage unit that stores operation histories of the ventilation unit, the heat source unit, and the air blowing unit. And a history display control unit that reads out the operation history of each of the ventilation unit, the heat source unit, and the blower unit from the storage unit and displays the operation history on the remote controller in accordance with a command input from the remote controller. .

  In the bathroom ventilation drying and heating system of the present invention, the operation history of the ventilation unit, the heat source unit, and the air blowing unit can be displayed on the remote controller by inputting a predetermined command from the remote controller. When visiting, display the above operation history on the remote controller to judge whether repair, inspection, parts replacement, etc. are necessary without looking inside the device body, and select the next visit time at an appropriate time. It becomes easy to do. Also, when it is determined that repair or inspection is necessary, the corresponding location can be determined from the operation history displayed on the remote controller, so repair and inspection can be performed in a relatively short time compared to when the corresponding location is unknown. Is possible. Therefore, in the bathroom ventilation drying heating system of this invention, it is easy to perform maintenance efficiently and to improve the reliability of maintenance.

Embodiment 2. FIG.
The bathroom ventilation drying / heating system of the present invention determines whether there is a part in the apparatus main body whose operation has changed to a level that requires maintenance based on the operation history stored in the storage unit, and requires the maintenance When it is determined that there is a maintenance determination unit, it is possible to add a maintenance determination unit that instructs the remote controller to notify.

  FIG. 5 is a functional block diagram schematically illustrating an example of a bathroom ventilation drying / heating system having a maintenance determination unit. A bathroom ventilation drying / heating system 70B shown in the figure includes an apparatus main body 50B instead of the apparatus main body 50A shown in FIG. 2, and the configuration of the apparatus main body 50B includes a control unit 30B including a maintenance determination unit 27. Except for this point, it is the same as the configuration of the apparatus main body 50A shown in FIG. Among the constituent elements shown in FIG. 5, the same constituent elements as those shown in FIG. 2 are designated by the same reference numerals as those used in FIG.

  The above-mentioned maintenance determination unit 27 determines whether there is a component in the apparatus main body 50B whose operation has changed to a level that requires maintenance, and the operation history of each functional unit 1, 5, 10, 20 stored in the storage unit 35. When it is determined that there is a part requiring maintenance, the remote controller 60 is instructed to notify via the transmission / reception processing unit 40.

  The storage unit 35 includes an exhaust fan that configures the ventilation unit 1, a heater that configures the heat source unit 5, an air supply fan that configures the blower unit 10, and a water supply / drainage device and a mist generation unit that configure the mist generation unit 20 For each total operation time (not shown), a threshold value for which maintenance is desired is set by the manufacturer of the bathroom ventilation drying / heating system 70B and stored in advance. Further, the threshold value for which maintenance is desired for the rotational speed of the exhaust fan, the heating rate of the heater, the rotational speed of the air supply fan, the water consumption speed in the mist generating unit 20, and the like is a bathroom ventilation drying heating system It is set by the manufacturer of 70B and stored in advance. In other words, even if the operation of the apparatus main body 50B is continued as it is, these threshold values are set so that the time until the apparatus main body 50B is failed is ensured. It is preferable to select so that the person in charge of maintenance can be called.

  The maintenance determination unit 27 obtains the operation history of each function unit 1, 5, 10, and 20 stored in the storage unit 35 and the above threshold value, for example, periodically or for each function unit 1, 5, 10, 20. It is read out every time a predetermined time has elapsed from the start of operation, and it is determined whether or not there is a part requiring maintenance. When it is determined that there is a part requiring maintenance, the remote controller 60 is instructed to notify via the transmission / reception processing unit 40 as described above. The remote controller that has received the above instruction from the maintenance determination unit 27 blinks or lights a predetermined display lamp, for example, or displays a predetermined message such as “Call” on the display panel unit 59a (see FIGS. 3 and 4). Is displayed to notify the user that maintenance is desired.

  The bathroom ventilation drying / heating system 70B configured as described above has the same technical effect as the bathroom ventilation drying / heating system 70A described in the first embodiment. In addition, since the above-described maintenance determination unit 27 is included, the user can call a maintenance person before a failure occurs in the apparatus main body 50B and the bathroom ventilation drying / heating system 70B becomes inoperable. There is also a technical effect that it is easy to avoid a situation in which the bathroom ventilation drying / heating system 70B cannot be used due to a failure. As a result, the reliability can be improved.

  The procedure of the processing by the maintenance determination unit 27 in the bathroom ventilation drying / heating system 70B that exhibits these technical effects can be appropriately selected. Hereinafter, an example of a processing procedure performed by the maintenance determination unit 27 will be specifically described with reference to FIGS. 6 and 7 while appropriately quoting the reference numerals used in FIG.

  FIG. 6 is a flowchart schematically showing an example of a processing procedure by the maintenance determination unit in the bathroom ventilation drying / heating system shown in FIG. 5. In the example shown in the figure, when the apparatus main body 50B starts operation, the maintenance determination unit 27 (see FIG. 5) performs a predetermined step of steps S1 to S8, and the maintenance target item based on the operation history of a predetermined part. It is determined whether A requires maintenance.

  In step S1 performed first, the storage target item A is read from the storage unit 35 (see FIG. 5). Next, in step S2, which is performed, it is determined whether or not the maintenance target item A exceeds the first threshold value X. The first threshold value X is an upper limit value for determining that the collection target part of the maintenance target item A is normal. When the first threshold value X is exceeded, it is determined that an abnormality or failure has occurred in the above part. Is done.

  When it is determined in step S2 that the maintenance target item A exceeds the first threshold value X, the process proceeds to step S3, and a predetermined signal is sent to the remote controller 60 (see FIG. 5) via the transmission / reception processing unit 40. The remote controller 60 is caused to perform a display operation indicating that an abnormality has occurred. Further, a signal for prohibiting the operation of the apparatus main body 50B is sent to the main control unit 21 (see FIG. 5), and the process is terminated. On the other hand, when it is determined that the maintenance target item A does not exceed the first threshold value X, the process proceeds to step S4.

  In step S4, it is determined whether or not the maintenance target item A exceeds the second threshold Y. The second threshold Y is an upper limit value for determining that maintenance is not yet required for the collection target component of the maintenance target item A. When the second threshold Y is exceeded, the above-described component maintenance is performed. Is determined to be desirable. As described above, it is preferable to select the second threshold value Y so that a person in charge of maintenance can be called before the apparatus main body 50B breaks down even if the operation of the apparatus main body 50B is continued.

  When it is determined in step 4 that the maintenance target item A exceeds the second threshold Y, the process proceeds to step S5, where a predetermined signal is sent to the remote controller 60 via the transmission / reception processing unit 40, and maintenance is desired. Is notified to the user by causing the remote controller 60 to perform a display operation (maintenance alert display). Even if the maintenance target item A exceeds the second threshold Y, the operation and operation of the apparatus main body 50B can be performed. Therefore, after performing Step S5, the process proceeds to Step S6, and the start or continuation of the commuting operation is controlled mainly. The unit 21 is instructed. On the other hand, when it is determined in step 4 that the maintenance target item A does not exceed the second threshold Y, the process proceeds to step S6 described above.

  Thereafter, the process proceeds to step S7, and it is determined whether or not the main control unit 21 has received a command for instructing the end of the operation of the apparatus main body 50B from the controller 60. When it is determined that the above command has not yet been received, the process returns to step S1 to repeat step S1 and subsequent steps. When it is determined that the above command has been received, the process proceeds to step S8, and the maintenance item A This determination process ends.

  The maintenance determination unit 27 determines whether or not maintenance is required for a maintenance target item set in advance for each functional unit based on the operation history of each functional unit 1, 5, 10, and 20 constituting the apparatus main body 50B. The determination is performed sequentially or in parallel as described above. Hereinafter, the process by the maintenance determination unit 27 will be described more specifically by taking as an example the determination of necessity of maintenance for the mist generation unit.

  FIG. 7 is a perspective view schematically showing an example of a mist generating unit in the bathroom ventilation drying / heating system shown in FIG. 5. The mist generating unit 20 shown in FIG. 1 includes a water storage tank 11 that stores water W that is a source of mist, a water supply pipe 12 a that supplies water to the water storage tank 11, and a drain pipe 12 b that discharges water from the water storage tank 11. And a total of four mist generators 13a to 13c that are arranged in the water tank 11 to generate mist, and 2 that are arranged in the water tank 11 at different height positions to detect water changes in the water tank 11. It has two water level detectors 14a and 14b, and a humidification promoting member 15 that is disposed in the water storage tank 11 and promotes the generation of mist.

  Moreover, although illustration is abbreviate | omitted in FIG. 7, the mist generation | occurrence | production part 20 also has the water supply pump arrange | positioned in the middle of the water supply pipe 12a, and the drainage pump arrange | positioned in the middle of the drainage pipe 12b. A water supply pump and a drainage pump comprise a water supply / drainage apparatus with the water supply pipe 12a and the drainage pipe 12b. The operation of the water supply / drainage device is controlled by the main control unit 21 (see FIG. 5). The said mist generating part 20 is arrange | positioned in the ventilation path of the air supply fan 7 which comprises the ventilation part 10 (refer FIG. 5), and discharge | releases mist in a bathroom. In FIG. 7, the air blowing direction by the air supply fan 7 is indicated by an arrow Db.

  In the mist generating unit 20 configured as described above, first, water is supplied to the empty water storage tank 11 from the water supply pipe 12a, and after the water level detector 14b arranged at the lower part of the water storage tank 11 detects the water W. When the water level detector 14a arranged at the upper part of the water storage tank 11 detects the water W, the main control unit 21 determines that the water is full and terminates the water supply. Thereafter, when the mist generating unit 20 starts operation, the mist generating devices 13a to 13d are operated to make the water W in the water storage tank 11 mist, and the water level in the water storage tank 11 gradually decreases. Water supply is performed again when the water level detector 14b stops detecting water.

  A part of the water W that has become mist passes through the humidification promoting material 15 and is released into the bathroom 100. However, as the use period of the humidification promoting material 15 increases, the humidification promoting material 15 may gradually become blocked. is there. When the humidification promoting member 15 is clogged, the amount of mist discharged from the apparatus main body 50B (see FIG. 5) is reduced, and the water level lowering rate in the water storage tank 11 is reduced. In order to detect the rate of decrease, the history management unit 23 (see FIG. 5) includes a mist generating unit 20 from when the water level detector 14a stops detecting the water W until the water level detector 14b stops detecting water W. The operation time is always counted, and the operation time is stored in the storage unit 35 as one of the operation histories of the mist generation unit 20.

  The maintenance determination unit 27 reads the above operation time stored in the storage unit 35, and when it is determined that the operation time has exceeded the first threshold, for example, a time corresponding to 150% of the initial operation time When it is determined that the threshold value is exceeded, the remote controller 60 is caused to display a notification that an abnormality or failure has occurred. Further, when it is determined that the second threshold is exceeded, for example, when it is determined that the time corresponding to 130% of the initial operation time has been exceeded, the remote controller 60 is caused to perform a maintenance alert display.

  Even if the maintenance alert display is displayed on the remote controller 60, the apparatus main body 50B (see FIG. 5) can be operated as usual for a while, so that a decrease in convenience can be suppressed compared to a case where the apparatus cannot be used suddenly. .

Embodiment 3 FIG.
The bathroom ventilation drying / heating system according to the present invention can be provided with a test operation control unit that causes the apparatus main body to perform a test operation in accordance with a command input from a remote controller. If this test operation control unit is added, it is difficult for the maintenance staff to be present when it is difficult to determine whether maintenance is necessary by only displaying the operation history, or when there is doubt about the judgment result of the maintenance judgment unit. It is possible to actually operate the main body of the apparatus below and have the maintenance staff judge the necessity of maintenance on the spot.

  FIG. 8 is a functional block diagram schematically illustrating an example of a bathroom ventilation drying / heating system having a test operation control unit. The bathroom ventilation drying / heating system 70C shown in the figure includes an apparatus main body 50C instead of the apparatus main body 50B shown in FIG. 5, and the configuration of the apparatus main body 50C includes a control unit 30C including a test operation control unit 29. Except for the point that it has, it is the same as the configuration of the apparatus main body 50B shown in FIG. Among the constituent elements shown in FIG. 8, the same constituent elements as those shown in FIG. 5 are denoted by the same reference numerals as those used in FIG.

  The test operation control unit 29 shown in FIG. 8 performs a test operation for each functional unit of the ventilation unit 1, the heat source unit 5, the blower unit 10, and the mist generation unit 20 when a predetermined command is input from the remote controller 60. Let it begin. During this time, the test operation control unit 29 controls the operation of the history management unit 23 and does not store the operation history of each of the function units 1, 5, 10, 20 in the storage unit 35, while The necessity of maintenance at 1, 5, 10, 20 is determined. When the maintenance determination unit 27 determines that there is a part that requires maintenance, the maintenance determination unit 27 instructs the remote controller 60 to notify the user. When it is determined that there is no part that requires maintenance, it is determined that there is no abnormality. The maintenance determination unit 27 notifies the remote controller 60.

  FIG. 9 is a flowchart schematically showing an example of a processing procedure during a test operation in the bathroom ventilation drying / heating system shown in FIG. 8. In the example shown in the figure, when the apparatus main body 50C (see FIG. 8) starts operation, the maintenance determination unit 27 or the test operation control unit 29 performs predetermined steps among steps S11 to Sn, and performs test operation and maintenance. Necessity determination is performed.

  In step S11 performed first, the test operation control unit 29 determines whether or not there has been an input operation of a test operation start command, such as a special operation using the remote controller 60, that is, double pressing or long pressing of the operation button. When it is determined that there is no special operation, the process proceeds to step S12 and the main control unit 21 starts normal operation. When it is determined that there is a special operation, the process proceeds to step S13 and the test operation control unit 29 executes the test operation. .

  When the test operation is executed, first, the process proceeds to step S14, and a test operation (indicated as “A operation” in FIG. 9) for obtaining an operation history for the item A among the plurality of maintenance target items to be subjected to the maintenance determination. The test operation control unit 29 causes a predetermined function unit 1, 5, 10, or 20 to execute. In the next step S15, the maintenance determination unit 27 determines whether or not the maintenance target item A requires maintenance based on the operation history obtained by performing step S14.

  If it is determined in step S15 that it is desirable to perform maintenance on the maintenance target item A, the process proceeds to step S16, and the maintenance determination unit 27 sends a predetermined signal to the remote controller 60 (see FIG. 8) via the transmission / reception processing unit 40. Then, the user is notified by causing the display unit to perform a maintenance alert display for the maintenance target item A.

  Since it is possible to operate and operate the apparatus main body 50C even if it is determined that it is desirable to perform maintenance on the maintenance target item A, the process proceeds to step S17 after performing step S16, and the operation history for the maintenance target item B The test operation control unit 29 causes the predetermined functional unit 1, 5, 10, or 20 to execute a test operation (indicated as “B operation” in FIG. 9) to obtain On the other hand, when it is determined in step 15 that the maintenance target item A does not require maintenance, the process proceeds to step S17 described above.

  In the next step S18, the maintenance determination unit 27 determines whether or not the maintenance target item B needs maintenance based on the operation history obtained by performing step S17. If it is determined in step S18 that it is desirable to perform maintenance on the maintenance target item B, the process proceeds to step S19, where the maintenance determination unit 27 sends a predetermined signal to the remote controller 60 via the transmission / reception processing unit 40, The user is notified by causing the display unit to perform maintenance alert display for item B. Thereafter, the process proceeds to step S20. The process also proceeds to step S20 when it is determined in step S18 that the maintenance target item B does not require maintenance.

  In step S20, the test operation control unit 29 performs a test operation (denoted as “C operation” in FIG. 9) to obtain an operation history for the item C among the plurality of maintenance target items to be subjected to the maintenance determination. 1, 5, 10, or 20 Thereafter, the same step as the above-described step S15, and if necessary, the same step as the above-described step S16 are performed, and further, up to the last item X of the plurality of maintenance target items to be subjected to the maintenance determination. Similar processing is repeated.

  In step S (n-2), the maintenance determination unit 27 determines whether or not maintenance is necessary based on the operation history obtained by performing the test operation for the maintenance target item X. If it is determined that it is desirable to perform the operation, the process proceeds to step S (n−1). In this step S (n-1), the maintenance determination unit 27 sends a predetermined signal to the remote controller 60 via the transmission / reception processing unit 40 to cause the display unit to perform a maintenance alert display for the maintenance target item X, Inform the user. Thereafter, the process proceeds to Step Sn. Further, when it is determined in step S (n−2) that maintenance is not required for the maintenance target item X, the process also proceeds to step Sn.

  In step Sn, the maintenance determination unit 27 sends a predetermined signal to the remote controller 60 via the transmission / reception processing unit 40 to cause the display unit to display that there is no abnormality in the apparatus main body 50C and notify the user. To do. By performing up to step Sn, the process at the time of test operation is completed.

  For example, when the test operation is performed on the mist generating unit 20 shown in FIG. 7, water supply to the water storage tank 11, drainage from the water storage tank 11, mist discharge operation, etc. are sequentially performed, and the drainage time and water level decrease in the process. Maintenance target items such as speed are measured. Then, the necessity of maintenance is determined for each maintenance target item, and when it is determined that maintenance is desired, the remote controller 60 performs a maintenance alert display. When maintenance alerts are displayed on the remote controller 60, the maintenance staff determines whether or not parts related to the item need to be cleaned, repaired, or replaced, and performs maintenance work.

  The bathroom ventilation drying / heating system 70C having the test operation control unit 29 described above has the same technical effect as the bathroom ventilation drying / heating system 70B described in the second embodiment, and is actually performed in the presence of a maintenance person. In addition, since the apparatus main body can be operated and the maintenance person can determine whether or not the maintenance is necessary on the spot, there is also a technical effect that the maintenance person can easily make an accurate determination.

  The bathroom ventilation drying / heating system of the present invention has been described with reference to the embodiment. However, as described above, the present invention is not limited to the above-described embodiment. For example, whether or not the mist generating unit is provided in the apparatus main body can be appropriately selected.

  In addition, the history management unit that stores the operation history of each functional unit in the apparatus main body in the storage unit includes a storage unit related to the parts and maintenance target items that are subject to the maintenance work when the maintenance work is performed. A function for resetting the operation history can be added. When this function is added to the history management unit, the operation history before maintenance is displayed on the display unit of the remote controller even after maintenance, and the maintenance person misunderstood, or the maintenance judgment unit was mistaken based on the operation history before maintenance. This makes it easier to prevent problems such as the user making a misunderstanding by making a determination and displaying a maintenance alert on the remote controller.

  The operation history is reset by the history management unit by providing a detector in the apparatus body for detecting that the maintenance work has been performed, and bathroom ventilation so that the history management unit automatically performs based on the detection result of the detector. A drying / heating system (apparatus main body) can be configured, or the bathroom ventilation drying / heating system can be configured to be performed by the history management unit in response to a command from the remote controller. In order to prevent the operation history from being reset due to an erroneous operation of the remote controller when the bathroom arousing drying and heating system is configured so that the history management unit resets the operation history in response to a command from the remote controller. In addition, it is preferable to make the command input operation relatively complicated, or to add a predetermined authentication function when inputting the command. Note that whether or not to make the history management unit independent from other units in the control unit can be selected as appropriate. For example, the function of the history management unit can be added to the main control unit, the history display control unit, etc., and the history management unit can be omitted.

  The history management unit described in the first embodiment, the second embodiment, or the third embodiment, the storage unit that stores the operation history of each functional unit, the history display control unit, the maintenance determination unit, and the test operation control unit However, at least one of them may be provided in the remote controller. About the bathroom ventilation drying heating system of this invention, a various deformation | transformation, modification, combination, etc. are possible besides having mentioned above.

  The present invention can be preferably applied to a bathroom ventilation drying heating system for home use or business use.
