Description

  The present invention relates to a bathroom air conditioner that is attached in a state of being embedded in a ceiling of a bathroom.

  As an equipment device installed in a house and air-conditioned by a built-in fan, there is known a device in which the operation time of the device is integrated and notified in order to notify the inspection time. As the operation time, it has been proposed to count the time during which the fan is rotating, or to count the time during which the device is energized.

  In addition, the operation time is stored in a non-volatile non-volatile memory so that it will not be lost even if the power supply to the equipment is cut off. Even if the control unit of the remote control unit is built in the remote control unit equipped with input means, even if the control unit of the device main body is replaced during maintenance, the operation time stored in the control unit on the remote control side is taken over. The device which prevents the memory | storage value of driving | running time from being lost is performed (patent document 1).

JP 2009-14302 A

  According to the prior art document 1, backup storage to the non-volatile memory on the remote control side is performed even when the operation is stopped. Therefore, at the time of maintenance, the remote controller brought by the maintenance operator is temporarily connected to the main body of the operation. When stopping after starting, the stored value of the non-volatile memory of the temporary remote controller is updated by the value stored in the non-volatile memory on the device body side, and the stored remote control is in another field, When connected to a device main body equipped with a new non-volatile memory, there is a problem that the device main body non-volatile memory is rewritten with the non-volatile memory value on the remote control side.

  The present invention has been made to solve the above problems, and an object of the present invention is to operate a non-volatile memory built in a remote controller in a temporary connection state between the air conditioner body and the remote controller during maintenance work. This prevents the stored value of the time from being overwritten by the operation time stored in the air conditioner body, and allows maintenance workers to perform maintenance work using the same remote control at many sites. .

In order to solve the above problems, according to the bathroom air conditioner according to the present invention, a device main body having a fan that sucks air in the bathroom, and a main body control unit that controls the operation of the fan, and the device main body, A remote controller that can communicate with each other and includes an input unit that is operated by a user and a remote control unit that transmits an operation command of the fan to the device main body based on the operation of the input unit; The main body control unit includes a main body clocking unit that counts the accumulated current time after the start of energization, and a nonvolatile main body nonvolatile memory that stores the energized accumulated time measured by the main body clocking unit, In the remote control unit, the bathroom air conditioner having a non-volatile remote control non-volatile memory that stores the energization integration time transmitted from the main body control unit, the main body control unit, The energization accumulated time stored in the body non-volatile memory is transmitted to the remote control unit, the energization accumulated time transmitted from the remote control unit is received, and the received energization accumulated time is received by the main body non-volatile memory. If the value is longer than the energization integration time stored in the memory, the energization integration time stored in the main body non-volatile memory is updated to the received energization integration time, and the remote controller control unit For a predetermined period of time, the storage processing in the remote controller nonvolatile memory based on the energization integration time transmitted from the main body control unit is prohibited, and the remote controller includes display means, and the remote control unit is supplied with power. During the predetermined time from the start, the energization integration time transmitted from the main body control unit can be displayed by the display means. And inhibits the storage process to the remote control memory of the current accumulation time has come.

  Therefore, the remote controller control unit brings in the maintenance contractor by prohibiting update storage in the remote controller non-volatile memory during the predetermined time from the start of power supply by the energization integration time transmitted from the device body. The operating time stored in the remote control non-volatile memory can be kept at zero. Therefore, it is not necessary to forcibly reset the non-volatile memory of the remote controller to zero when connecting the tentatively connected remote controller to another air conditioner body at another maintenance site, improving the maintenance workability. Forgetting the zero reset, the main body non-volatile memory is rewritten with the memory value on the remote control side, and an alarm is not generated based on the incorrect total energization time.

Further, it is possible to check the current integration time of the air-conditioner main body, it is possible to perform the maintenance work in accordance with the energization integrated time.

Further, according to the bathroom air conditioner according to the present invention, the remote control unit, when a specific input accompanying the end of the maintenance work is performed by the input means during a predetermined time after the start of power feeding, The energization integration time transmitted from the main body control unit at the time is updated and stored in the remote controller nonvolatile memory.
Accordingly, when the end of the maintenance work is input, the remote control nonvolatile memory is forcibly updated and stored, so that the stored contents of the main body nonvolatile memory can be reliably backed up in the remote control nonvolatile memory.

Further, according to the bathroom air conditioner according to the present invention, when the specific input accompanying the end of the maintenance work is performed by the input means, the remote control unit stores it in the remote controller nonvolatile memory as status information. When the accumulated energization time stored in the remote controller non-volatile memory exceeds a predetermined time, an alarm is displayed if status information is not stored, and no alarm is displayed if status information is stored. It is characterized by that.
Accordingly, since the status information is also stored in the remote controller nonvolatile memory and inherited, the maintenance work can be easily performed by calling the status information.

  According to the present invention, even when the control unit of the apparatus main body is replaced during maintenance, the maintenance operator can reliably perform integrated energization even if the maintenance is performed using the maintenance remote controller without special attention. There is an effect that time can be taken over.

It is a block diagram which shows the whole structure of the bathroom air conditioner in connection with this invention. . It is a flowchart which shows operation | movement of the apparatus main body of this invention. It is a flowchart which shows operation | movement of the remote control of this invention.

  FIG. 1 is a block diagram showing an overall configuration of a bathroom air conditioner A related to the present technology.

As shown in FIG. 1, the bathroom air conditioner A is composed of a device main body 1 installed in a bathroom Y driven by a commercial power source, and a remote controller 9 that is fed from the device main body 1 and can communicate with the device main body 1. ing.
The device main body 1 is installed on the ceiling of the bathroom Y, the remote controller 9 is installed in the washroom S, and both are wired. Although illustration is omitted here, AC 100 V commercial power is supplied to the device main body 1, and DC 5 V rectified and stepped down inside the device main body is supplied as drive power for the remote controller 9.

  The apparatus main body 1 includes a fan 6 that sucks air in the bathroom Y, a load 6 including a processing unit that heats the air sucked by the fan with an electric heater, a main body microcomputer 3 that controls the operation of the load 6, and the main body. The main body timing means 4 for measuring the energization time to the microcomputer 3, the non-volatile main body nonvolatile memory 5 for accumulating and storing the energization time from the main body timing means 4, and the energization time read from the main body nonvolatile memory 5 Is provided as a control board in a replaceable manner.

When the user operates the input unit 16 such as a push button, the remote controller 9 generates a control signal based on the operation by the remote control microcomputer 12 and transmits the control signal to the device body 1 by the communication unit 11.
In addition, the remote controller 9 is provided with a remote controller control unit 10 including a nonvolatile remote controller nonvolatile memory 14, a remote controller RAM 13, and a remote controller display means 15 so as to be exchangeable as a control board.

The energization time is counted up in units of one hour by the main body timing means 4 of the device main body 1.
When the energization time accumulated by the main body time counting means 4 is counted up, the device main body 1 stores the counted energization time in the main body non-volatile memory 5 and the energization counted up by the communication means 2. The time is transmitted to the remote controller 9. The remote controller 9 writes the energization time received from the device body 1 in the remote controller nonvolatile memory 14.
As described above, the energization time accumulated by the main body timing unit 4 is stored in two locations, the main body nonvolatile memory 5 and the remote controller nonvolatile memory 14.

  When the commercial power supply is supplied again after the supply of the commercial power supply is stopped, the device main body 1 reads the energization time stored in the main body nonvolatile memory 5 and stores it in the main body RAM 8. Similarly, the remote controller 9 reads the energization time stored in the remote controller nonvolatile memory 14 and stores it in the remote controller RAM 13.

  Thereafter, the device main body 1 instructs the remote controller 9 to transmit the energization time through the communication unit 2. When receiving an instruction to transmit the energization time, the remote control 9 transmits the energization time stored in the remote control RAM 13 to the device main body 1.

The device main body 1 compares the energization time stored in the main body memory 1 with the energization time sent from the remote controller 9, stores the larger time in the main body memory 1, and Send time.
The remote controller 9 stores the energization time sent from the main body in the remote control RAM 13.

  After the comparison of the energization time by the device main body 1, if both the device main body 1 and the remote controller 9 store the compared energization times in the respective storage means, the energization time stored in the main body nonvolatile memory 5 Is zero when shipped from the factory. Therefore, when the main body control unit of the device main body is replaced, the energization time stored in the remote controller is greater than the energization time stored in the main body nonvolatile memory 5. Therefore, the energization time stored in the remote control storage means 10 is handed over to the replaced new main body control unit.

  However, if the maintenance operator brings another remote controller for the purpose of identifying the failure location, etc., and temporarily operates with the device main body, it is stored in the main body non-volatile memory 5 of the device main body 1. The stored value of the remote controller non-volatile memory 14 of the provisional remote controller is updated by the stored value, and the stored remote controller is connected to the main body of the device equipped with the new main body non-volatile memory 5 at another site. Then, the main body non-volatile memory 5 is rewritten by the remote control non-volatile memory 14.

  Therefore, the device main body 1 and the remote controller 9 reset the energization time stored in each memory for 2 hours after the respective control units are reset, that is, after the commercial power is supplied, By not performing the update, the problem that the energization time stored in the remote controller nonvolatile memory 14 of the remote controller brought by the maintenance worker is updated is solved.

When two hours have elapsed from the reset, the device main body 1 compares the energization time stored in the main body RAM 8 with the energization time stored in the main body non-volatile memory 5, and if the values are different, the device main body 1 stores it in the main body RAM 8. The energized time being stored is stored in the main body nonvolatile memory 5.
In a bathroom air conditioner, since commercial power is usually supplied at all times, even if the main body control unit or remote control is replaced due to maintenance, the larger energization time, that is, the energization of the equipment after 2 hours. Time is stored in the storage means of both the main body control unit and the remote controller.

The remote controller 9 has a function of displaying the energization time stored in the remote control RAM 13 on the remote control display means 15, and the remote control RAM 13 stores the energization time as a result of comparison by the device body 1. On the display means 11 of the remote controller 9, the result of comparison by the device main body 1 is displayed.
Thereby, the maintenance worker can confirm the energization time of an apparatus.

  Here, the main body nonvolatile memory 5 and the remote controller nonvolatile memory 14 store not only the energization time but also status information. The status information is information indicating whether or not the inspection has been completed. If the energization time is 10 years or more and before the inspection is completed, the remote control display means 15 is displayed to prompt the inspection. , Do not display to prompt inspection.

  Further, when the inspection work is completed, the maintenance worker makes a specific input at the end of the work with the input means 16 of the remote controller 9. When a specific input operation is performed, the remote controller 9 changes the status information to “completed inspection” and transmits the status information to the device main body 1 by the communication unit 11.

However, since the inspection work is performed with the breaker shut off and the supply of commercial power stopped,
As described above, since the nonvolatile memory is not updated within 2 hours from the reset, if the maintenance worker shuts down the breaker for some reason after the work is completed, the work completion information is correctly nonvolatile. Although it is not stored in the memory and the inspection is completed, a display prompting the inspection is displayed on the remote control display unit 15 again.

  Therefore, the device body 1 and the remote controller 9 store the energization time and the status information in the storage means when the status information has changed even within 2 hours from the reset.

  Next, the operation based on the flowchart will be described. FIG. 2 is an operation flow of the device main body 1, and FIG.

At the time of reset, the device body 1 resets the 2-hour measurement timer to 0 (S201). This timer is used for the purpose of preventing the energization time and status information from being written in the main body nonvolatile memory 5 within 2 hours from the reset.
Similarly, the remote controller 9 also resets the 2-hour measurement timer to 0 when reset (S301).

Next, the device main body 1 reads the energization time and the status information from the main body nonvolatile memory 5 and stores them in the main body RAM 8 (S202).
Similarly, the remote controller 9 reads the energization time and status information from the remote controller nonvolatile memory 14 and stores them in the remote controller RAM 14 (S302).

Next, the device body 1 transmits a command to transmit the energization time and status information to the remote controller 9 (S203).
This is the part that is executed only once at reset.

When receiving a power-on time and status information transmission instruction command from the device main body 1, the remote controller 9 transmits the power-on time and status information stored in the remote control RAM 13 to the device main body 1.
Immediately after the reset, the remote controller RAM 13 contains the value stored in the remote controller nonvolatile memory 14, so the remote controller 9 transmits the energization time and status information stored in the remote controller nonvolatile memory 14. Become.

Upon receiving the energization time and status information from the remote controller 9 (S204), the device body 1 checks whether there is a change in the status information (S205). When the status is changed, the device main body 1 overwrites the status information stored in the main body RAM 8 with the status information received from the remote controller 9 (S206), regardless of whether two hours have passed since the reset. First, status information is written in the main body non-volatile memory 5 (S207).
As for the energization time, the energization time stored in the main body RAM 8 is compared with the time received from the remote control 9 (S208). If the time received from the remote control 9 is larger, the energization time stored in the main body RAM 8 is compared. The time is overwritten with the energization time received from the remote controller 9 (S209). At this time, the apparatus main body 1 writes the energization time in the main body non-volatile memory 5 only when two hours or more have passed since the reset (S210).
Thus, immediately after resetting, that is, immediately after supplying commercial power, the larger energization time is stored in the main body RAM 8 between the energization time stored in the main body nonvolatile memory 5 and the energization time stored in the remote control nonvolatile memory 14. Although stored, the energization time stored in the main body nonvolatile memory 5 is not updated.

Upon receiving the energization time and status information from the remote controller 9 (S204), the device main body 1 receives the energization time and status stored in the main body RAM 8 regardless of whether or not the status has changed and whether the energization time has been determined. Information is transmitted to the remote controller 9 (S212).
When receiving the energization time and status information from the device body 1 (S307), the remote controller 9 stores them in the remote controller RAM 13 (S308). At this time, the value of the device main body RAM 8 and the value of the remote control RAM 13 are always the same value.

At this time, the remote controller 9 writes the energization time in the remote controller nonvolatile memory 14 only when two hours or more have passed since the reset (S309) (S310).
Thus, immediately after resetting, that is, immediately after supplying commercial power, the larger energization time is stored in the remote control RAM 14 between the energization time stored in the main body nonvolatile memory 5 and the energization time stored in the remote control nonvolatile memory 14. Although stored, the energization time stored in the remote control nonvolatile memory 14 is not updated.

The energization time is counted up in units of one hour by the main body timing unit 4 of the main body 1 (S213, S214). At this time, when the energization time is counted up, if 2 hours or more have elapsed since the reset, the energization time is stored in the main body nonvolatile memory 5 (S216).

  When the energization time is counted up, the device main body 1 transmits the energization time and status information stored in the main body RAM 5 to the remote controller 9 (S217).

  In this way, the energization time and status information stored in the main body RAM 5 of the device main body 1 and the energization time and status information stored in the remote control RAM 13 of the remote control 9 are always set to the same value. .

  Here, if the energization time is 10 years or more and the status information is before inspection (S315), the remote controller 9 displays an alarm for prompting inspection on the remote control display means 15 (S316).

After the inspection is completed, when the maintenance person performs an inspection completion operation by the input means 16 (S303), the status information stored in the remote controller RAM 13 becomes the inspection completed (S304). At this time, it is assumed that two hours or more have passed even if two hours have not passed since the reset (S305).
At the same time, the energization time and status information stored in the remote control RAM 13 is transmitted to the device body 1 (S305).

  Upon receiving the energization time and status information from the remote controller 9, the device main body 1 performs the processing as described above (S204 to S211), and the remote control 9 stores the energization time and status information stored in the main body RAM 8. Transmit (S212). At this time, the status information stored in the main body RAM 8 is a value sent from the remote controller 9, that is, the inspection has been completed.

  As described above, since the remote controller 9 has passed two hours or more (S305), when the energization time and status information are received from the device body 1, the received energization time and status information are stored in the remote controller nonvolatile memory 14. Write to.

  When the energization time display operation is performed by the input means 16 (S313), the remote controller 9 displays the energization time stored in the main body RAM 8 on the remote control display means 15 (S314).

  With the above processing, even when the main body control unit on the main body side is replaced during maintenance, the maintenance operator can reliably take over the operation time even if the maintenance work is performed without paying special attention.
