Description

  The present invention relates to an apparatus for controlling an air conditioner by a programmed microcomputer, and more particularly to control during long-term use.

  Generally, household electric appliances including air conditioners have a standard design use period, and if the use is continued beyond the use period, there is a possibility that an unforeseeable malfunction or failure may occur.

  Conventionally, this type of air conditioner control device uses an inspection time when the integrated value of the operating time of the entire system or the integrated value of the energization time of the main components exceeds a predetermined value. If the operation time or energization time exceeding the inspection time reaches a predetermined time, the operation is forcibly stopped and the subsequent operation is prohibited (see, for example, Patent Document 1).

  FIG. 3 shows a flowchart of a program executed by the microcomputer of the conventional air conditioner control device described in Patent Document 1. In FIG. 3, only when the operation is in step 301, the process proceeds to step 302 and the operation time (T) is integrated and stored in the nonvolatile memory. When the integrated value of the operation time (T) exceeds the designed standard use period (T1) in step 303, the operation proceeds to step 304 to stop the operation, and then the light emitting element of the display unit blinks in step 305. Then, the arrival of the inspection time is notified, and only when the operation is in operation in step 306, the operation proceeds to step 307 and the operation time (T) is integrated and stored in the nonvolatile memory. When the integrated value of the operation time (T) exceeds the total of the standard use period (T1) and the predetermined time (T2) in step 308, the process proceeds to step 309 and the subsequent operation is prohibited.

  However, in the above-described conventional configuration, if the user continues to use the alarm when the inspection time has not been correctly understood by the user, the user will suddenly become unable to drive, resulting in dissatisfaction with the user. It is expected that

  The present invention solves the above-mentioned conventional problem, and when the operation is not possible without being aware of the arrival of the inspection time and the operation cannot be performed, until the inspection is completed after the inspection is requested, or An object of the present invention is to provide a control device for an air conditioner that allows a user to continue using it after recognizing the risk until a new air conditioner is purchased and installed.

  In order to solve the above-described conventional problems, the air conditioner control device of the present invention is only operated by reducing the upper limit of the compressor operating frequency only by a method other than remote control operation after prohibiting normal operation. Is something that can be started.

  This makes it possible to perform emergency operation with reduced air-conditioning performance by checking the instruction manual or contacting the manufacturer's repair consultation service or the purchase shop even after operation is disabled. .

  The control device for an air conditioner according to the present invention continues to be used without noticing the arrival of the inspection time, and when the operation becomes impossible, the inspection is requested and the inspection is completed, or new air is used. Until the harmonic machine is purchased and installed, the user can continue to use it after recognizing the risk, and can strongly encourage inspection or replacement.

The flowchart of the program which the microcomputer of the control apparatus of the air conditioner in Embodiment 1 of this invention performs Flowchart of program executed by microcomputer of conventional air conditioner control device

  The present invention is an apparatus for controlling an air conditioner by means of a programmed microcomputer, the detection means for detecting that the standard use period in the design of the air conditioner has arrived, and the inspection when the standard use period has come And a notification means for notifying that it is time, and once the detection means detects the arrival of the standard use period, the operation is temporarily stopped, and thereafter, the notification means continuously notifies the inspection time, and the standard When the usage time after the usage period reaches a predetermined time, normal operation is prohibited, and after that, only operation with the upper limit of the compressor operation frequency lowered can be started only by a method other than remote control operation. By doing so, even after operation became impossible, if you look at the instruction manual or contact the manufacturer's repair consultation service or the store where you purchased it, the air conditioning performance deteriorated The user is aware of the risks until he / she can perform an emergency operation in the state, until he / she requests an inspection and completes the inspection or purchases and installs a new air conditioner. Use can be continued, and can be strongly encouraged to check or replace.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
1 is a block diagram showing a configuration of an air conditioner control device according to Embodiment 1 of the present invention, and FIG. 2 is a program executed by a microcomputer of the air conditioner control device according to Embodiment 1 of the present invention. It is a flowchart.

  In FIG. 1, 1 is an indoor unit, 2 is a remote controller, 3 is a microcomputer for controlling the indoor unit, 4 is a program executed by the microcomputer 3, 5 is a receiving unit for receiving a signal from the remote control 2, and 6 is a power source being cut off. Is a rewritable non-volatile memory capable of holding data, 7 is a display unit on which a light emitting element for informing operation status and setting is arranged, and 8 is an emergency operation switch for starting emergency operation. In general, the user operates the remote controller 2 to transmit signals such as turning off / on and temperature setting to the indoor unit 1, and the indoor unit 1 is controlled as an air conditioner in conjunction with an outdoor unit (not shown). Perform the action.

  The operation of the program 4 shown in FIG. 1 will be described below according to the flowchart of FIG. In addition, about the step same as the past, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  When the microcomputer 3 detects the start of emergency operation in step 201 after prohibiting operation in step 309, the microcomputer 3 proceeds to step 202 and permits operation, and in step 203, the upper limit of the compressor operation frequency is set lower than normal. (For example, 50% of normal time).

  In general, the emergency operation switch 8 is disposed inside the front panel of the indoor unit 1 so that the user cannot easily operate it. Therefore, it is very troublesome for the user to operate the emergency operation switch 8 every time the air conditioner is operated. In addition, when the upper limit of the compressor operating frequency is set to 50% of the normal time, the air conditioning performance is significantly lowered. Therefore, comfort is significantly impaired in the hot and cold season. Therefore, these two factors can prevent the user from continuing to use without requesting inspection.

  As described above, in the present embodiment, after the operation is prohibited in step 309, the start of the emergency operation is detected in step 201, the operation is permitted in step 202, and the upper limit of the compressor operating frequency is determined in step 203. Even after the operation has become impossible by setting the value lower than normal, if you check the instruction manual or contact the manufacturer's repair consultation service or the store where you purchased the Emergency operation can be performed, and until the inspection is completed after the request is made, or until a new air conditioner is purchased and installed, the user will continue to use the product while being aware of the risks. Can be strongly encouraged to check or replace.

  In the present embodiment, the driving start method other than the normal remote control operation is the emergency driving start by the emergency operation switch 8, but other methods may be used as long as the user feels troublesome. Moreover, the upper limit set value of the compressor operating frequency in step 203 is an example, and does not limit the present invention.

  As described above, when the air conditioner control device according to the present invention continues to be used without noticing the arrival of the inspection time and cannot be operated, the inspection is requested and the inspection is completed. Until the user purchases and installs a new air conditioner, it is possible for the user to recognize the risk and continue using it, and it is possible to strongly encourage inspection or replacement. It can also be applied to household electrical equipment.
