The present invention comprises an operation unit provided in a main body for instructing the operation of the main unit, a receiving unit for receiving signals from remote operation means capable of instructing the operation of the main unit, and transmitting instructions from the operation unit and the remote operation means to the main unit. and a control unit for executing the air conditioner, the control unit notifies the abnormality and stops the operation when an abnormality of the main body is detected, the abnormality is the first abnormality, and the cause of the abnormality has been eliminated. In this case, the instruction to cancel the notification of the abnormality or start the operation from the operation unit is executed, but the cancellation of the notification of the abnormality or the instruction to start the operation from the remote control means is not executed. When the first abnormality occurs in the main body, the cause of the abnormality cannot be eliminated by the user who is far away. The operation will be started while the vehicle is still in operation, and there is a risk of impairing safety. Therefore, when the first abnormality occurs in the main body, the safety of the main body can be improved by preventing the operation of the main body from being started from the remote control means. In addition, when the cause of the abnormality is eliminated, the operation unit cancels the notification of the abnormality or instructs to start operation, so immediately after restarting the operation of the main unit, can be prevented from stopping, improving convenience.

The apparatus also includes tilt detection means for detecting tilt of the main body, and the first abnormality includes an abnormality detected by the tilt detection means. If the tilt detection means detects that the main unit is tilted or overturned, the airflow in the airflow path will change from when the main unit is installed normally, and the temperature inside the main unit may rise unexpectedly. have a nature. Safety is compromised if the operation of the main body is started in such a state. Therefore, by including the abnormality detected by the tilt detection means in the first abnormality, it is possible to prevent an unexpected temperature rise in the main body and improve the safety of the main body.

In addition, it has a suction port for taking indoor air into the main body and a blowout port for discharging air from the main body, and the first abnormality includes a malfunction in which the suction port or the blowout port is blocked. When the suction port and the blowout port are blocked, the inside of the main body becomes hot.

Therefore, by including an abnormality in which the suction port or the outlet is blocked in the first abnormality, it is possible to prevent the inside of the main body from being operated in a high temperature state, thereby improving the safety of the main body.

An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a humidifier is used as an example of an air conditioner.

FIG. 1 is an external perspective view of the humidifier of this embodiment, and FIG. 2 is a cross-sectional configuration diagram of the humidifier of this embodiment. On the upper surface of the main body 1 of the humidifier, there are provided an operation unit 2 provided with a large number of switches for instructing the operation of the humidifier, a display unit 3 for displaying the operating state, and an outlet 4 for blowing out humidified air. there is

A suction port 5 for taking indoor air into the main body 1 is provided on the rear surface of the main body 1.例文帳に追加At the bottom of the main body 1, a water tank portion 7 is supplied with water from a water tank 6 to store a certain amount of water, and a vaporization filter 8 having water absorption is arranged in the water tank portion 7. 7 and vaporization filter 8 constitute humidifying means 9 for generating humidified air. A part of the vaporization filter 8 is immersed in the water in the water tank part 7, and is moistened by sucking up this water.

A blower 12 consisting of a fan 10 and a motor 11 is provided above the evaporative filter 8 . By driving the blower 12 , air is blown through a blowing path from the suction port 5 to the blowout port 4 . A heater 13 for heating the air introduced from the suction port 5 into warm air is provided upstream of the vaporization filter 8 in the air blowing path. A main body internal temperature detecting means 25 for detecting the internal temperature is arranged.

The humidifying device is also operable by remote control means 40 (see FIG. 3) and includes a receiver 14 for receiving signals from the remote control means 40 . Note that the remote control means 40 is, for example, a remote controller attached to the humidifier, a learning remote controller that stores and uses a signal instructing the operation of the humidifying device, or a smartphone connected to the main body 1 or the learning remote controller. can be used, and the method is not particularly limited.

FIG. 3 is a block diagram of the humidifying device of this embodiment. A control unit 30 that controls the operation of the main body 1 receives instructions regarding driving from the operation unit 2 and the reception unit 14 . Various switches to be operated by the user are provided in the operation unit 2. In this embodiment, an operation switch 20 for instructing the start and stop of operation of the main body 1 and a humidity setting switch 21 for setting the indoor target humidity are provided. I have. Furthermore, information from various detection means is input to the control unit 30 . As various detection means, in this embodiment, main body temperature detection means 25 for detecting the temperature inside the main body 1, room temperature detection means 26 for detecting the temperature of the room air, and humidity detection means 27 for detecting the humidity of the room air. and a tilt detection means 28 for detecting the tilt of the main body. Various switches and various detection means are not limited to the present embodiment, and other switches and detection means may be provided.

The output side of the control section 30 is connected to the display section 3 , the blower 12 and the heater 13 . The control unit 30 sets the rotational speed of the blower 12 and the output of the heater 13 to perform the humidification operation based on the input instructions and information regarding the operation. In addition to displaying the indoor air humidity detected by the humidity detection means 27 on the display part 3, the control part 30 detects an abnormality of the main body 1 from information input from various detection means, and responds to the abnormality. Show error code. In the present embodiment, an error is notified by displaying an error code. However, the operation unit 2 may be provided with an error lamp that lights or blinks when an error occurs, or an alarm sound may be generated.

The operation of the humidifying device described above will be described. When the humidifier is instructed to start operation from the operation switch 20 or the remote control means 40, the air blower 12 is driven to draw indoor air into the main body 1 through the suction port 5. As shown in FIG. The air taken in becomes warm air while passing through the heater 13 , and the warm air becomes humidified air by passing through the vaporization filter 8 , and the humidified air is discharged into the room from the outlet 4 .

The control unit 30 performs the humidification operation based on the inputted instruction and information regarding the operation, and brings the indoor humidity close to the target humidity set by the humidity setting switch 21 . When an instruction regarding driving is executed from the operation unit 2 or the remote control means 40, a buzzer sound such as "beep" or "beep" is emitted from the main unit 1 in response to the instruction to inform the user that the instruction has been executed. Inform.

Further, the control unit 30 determines whether or not there is an abnormality in the main body 1 based on signals from various detection means, and when an abnormality is detected, notifies the main body 1 of the abnormality and stops the operation of the main body 1 . This anomaly is divided into a first anomaly and a second anomaly. The first abnormality refers to an abnormality in which the operation of the main body 1 can be started normally by the user addressing the cause of the abnormality, and a specific example of the first abnormality will be described later. A second abnormality refers to an abnormality that requires repair of the main body 1 . Even if an abnormality can be dealt with by the user, if it occurs several times in a row during a predetermined period of time or occurs at the same time as other abnormalities, it should be treated as the second abnormality instead of the first abnormality. may be

When the abnormality is the first abnormality, the control unit 30 can cause the main body 1 to cancel the notification of the abnormality from the operation unit 2 or to instruct the operation start. That is, when the user operates the operation switch 20 of the operation unit 2 after dealing with the cause of the abnormality, the notification of the abnormality is canceled and the operation is started. It should be noted that the instructions to cancel the notification of the abnormality and to start the operation may be independent instructions. be. Note that the switch operation described above is not limited to the operation switch 20, and may be performed by other switches.

By the way, when the first abnormality occurs in the main body 1, the user who is far away cannot solve the cause of the abnormality. Therefore, if the operation start instruction from the remote control means 40 is executed, the operation will be started with the first abnormality occurring in the main body 1 . It is highly likely that there is no one near the main body 1 when remote control is being performed, and if the vehicle continues to drive without dealing with the abnormality in such a situation, safety may be compromised. Therefore, when the abnormality is the first abnormality, the control unit 30 does not cause the remote control means 40 to cancel the notification of the abnormality or to instruct the start of operation. As a result, it is possible to prevent the operation of the main body 1 from being started by remote control while the first abnormality is occurring, thereby improving the safety of the main body 1 .

In particular, when the main body 1 does not have a transmission section for transmitting information regarding the abnormality of the main body 1 to the remote control means 40, the fact that the operation of the main body 1 has stopped due to the first abnormality cannot be communicated to the user who is far away. Therefore, it is conceivable that the command to start operation may be given without noticing the abnormality. However, since the control unit 30 does not execute this instruction, it can be used safely.

In addition, even if the main body 1 has a transmission unit and the fact that the operation of the main body 1 has stopped due to the first abnormality is transmitted to a user who is far away, there is a possibility that the operation start is instructed by an erroneous operation. . Even in such a case, the operation of the main body 1 can be prevented from being started, so the safety of the main body 1 can be improved.

Furthermore, if the first abnormality has occurred and the instruction from the remote control means 40 has not been executed, the main body 1 may be configured not to emit a buzzer sound. Thereby, it is possible to inform the user in the room that the instruction from the remote control means 40 has not been executed.

Further, as another embodiment, the condition for canceling the notification of abnormality or executing the instruction to start operation from the operation unit 2 is that the abnormality is the first abnormality and the cause of the abnormality has been eliminated. can also Whether or not the cause of the abnormality has been eliminated is determined by the control unit 30 based on the detection results of various detection means. As a result, it is possible to prevent the operation of the main body 1 from stopping again due to the same abnormality immediately after starting the operation of the main body 1 from the operation unit 2, thereby improving the convenience.

Here, the first abnormality will be described with a specific example.

The first abnormality may include an abnormality detected by the tilt detection means 28 . The tilt detection means 28 detects that the main body 1 is tilted by a predetermined angle or more, and detects that the main body 1 is tilted or overturned due to shaking due to an earthquake or a person hitting the main body 1. - 特許庁When this abnormality occurs, the flow of air in the blowing path changes from when the main body 1 is normally installed, and there is a possibility that the temperature inside the main body 1 rises unexpectedly. If the operation of the main body 1 is started in such a state, the safety is impaired. Also, if the circuit board is energized while the water spilled from the water tank 7 adheres to the electrical parts, the circuit board may be damaged. be. Therefore, by including the abnormality detected by the tilt detection means 28 in the first abnormality, it is possible to prevent an unexpected temperature rise and board failure in the main body 1, thereby improving safety. . Furthermore, when the operation of the main body 1 stops due to this abnormality, the user approaches the main body 1 to operate from the operation unit 2, so that the user can set the main body 1 horizontally and check the surroundings of the main body 1. can also be encouraged. The confirmation of the surroundings of the main body 1 means, for example, whether or not water is spilled from the water tank section 7 around the main body 1 .

Also, the first abnormality may include an abnormality due to blockage of the suction port 5 or the blowout port 4 . When the suction port 5 or the blowout port 4 is clogged with an object or dust accumulates, the temperature inside the main body 1 rises, and this is detected by the main body internal temperature detecting means 25. - 特許庁If the operation of the main body 1 is started without resolving this abnormality, the high temperature state inside the main body 1 will not be resolved until the abnormality is detected again and the operation of the main body 1 is stopped. Therefore, by including the abnormality due to the blockage of the suction port 5 or the blowout port 4 in the first abnormality, it is possible to prevent the inside of the main body 1 from being operated in a high temperature state, thereby improving the safety. Furthermore, when the operation of the main body 1 stops due to this abnormality, when the user approaches the main body 1 in order to operate it from the operation unit 2, it becomes easier for the user to notice objects and dust blocking the suction port 5 and the air outlet 4. You can also prompt them to take actions such as moving things or removing dust.

Besides, the first anomaly can also include an anomaly in the temperature of the room air taken in from the suction port 5 . This abnormality is detected when the room temperature detected by the room temperature detection means 26 deviates from the predetermined range.
